Reduced recurrence rate and comparable functionality after wide resection and reverse total shoulder arthroplasty with allograft-prosthetic composite versus curettage for proximal humeral giant cell tumor: a multicenter retrospective study

BACKGROUND

Giant cell tumors of bone (GCTBs) are rare, aggressive tumors, and the proximal humerus is a relatively rare location for GCTBs; limited evidence exists on which surgical approaches and reconstruction techniques are optimal. In the largest case series to date, we evaluated the recurrence rate of proximal humeral GCTBs and the functional outcomes of different resection and reconstruction options in this multicenter study.

METHODS

All 51 patients included in this study received initial surgical treatment for proximal humeral GCTBs from January 2007 to December 2020, with a minimum 2-year follow-up period. Local recurrence and functional outcomes were statistically analyzed in relation to demographic, clinical, and primary surgical variables. Functional outcomes were reported by patients and were assessed by the Musculoskeletal Tumor Society score and QuickDASH instrument (shortened version of the Disabilities of the Arm, Shoulder and Hand instrument).

RESULTS

The mean follow-up period was 81.5 months (range, 30-191 months), and the overall recurrence rate was 17.6% (9 of 51 patients). The majority of recurrences (n = 7) occurred in the first 2 years of follow-up. The intralesional curettage group (n = 23) showed a statistically significant difference in the recurrence rate compared with the en bloc resection group (n = 28) (34.8% vs. 3.6%, P = .007). Among shoulders receiving en bloc resection, 16 were reconstructed with hemiarthroplasty; 8, reverse total shoulder arthroplasty (rTSA) with allograft-prosthetic composite (APC) reconstruction; and 4, arthrodesis. On the basis of intention-to-treat analysis, the mean functional Musculoskeletal Tumor Society scores of the groups undergoing curettage, rTSA with APC, hemiarthroplasty, and arthrodesis were 26.0 ± 3.1, 26.0 ± 1.7, 20.3 ± 2.8, and 22.5 ± 1.3, respectively (P < .001 [with P < .001 for curettage vs. hemiarthroplasty and P = .004 for rTSA with APC vs. hemiarthroplasty]) and the mean QuickDASH scores were 14.0 ± 11.0, 11.6 ± 4.5, 33.1 ± 11.8, and 21.6 ± 4.7, respectively (P < .001 [with P < .001 for curettage vs. hemiarthroplasty and P = .003 for rTSA with APC vs. hemiarthroplasty]).

CONCLUSIONS

On the basis of our data, en bloc resection followed by reverse shoulder arthroplasty showed a lower recurrence rate and no significant difference in functional outcome scores for proximal humeral GCTBs compared with intralesional curettage. Therefore, we believe that rTSA with APC may be reasonable for the initial treatment of proximal humeral GCTBs.

Time to full weight-bearing with the use of a calcium sulfate-calcium phosphate bone substitute as a bone void filler following extended curettage in the treatment of primary benign bone tumours

PURPOSE

The primary objective of this study was to determine time to full weight-bearing after the use of a calcium-sulfate-calcium phosphate bone substitute (CaSO4/CaPO4) as a bone void filler in the treatment of primary benign bone tumours following intralesional curettage. The secondary objectives were to determine surgical complications and recurrence rates.

METHODS

Retrospective review of patients identified from a surgeon-specific orthopaedic oncology database, who underwent curettage of benign bone tumours and subsequent bone void filling with CaSO4/CaPO4.

RESULTS

A total of 39 patients (20 males, 19 females) met inclusion criteria with an average age of 31 years (range: 13 to 62 years), a median follow-up of 3.7 years, and a maximum follow-up of 11 years. The most common tumour diagnosis was giant cell tumour of bone (GCT) (n = 19), and the most common location was the proximal tibia (n = 9). The mean volume of tumour excised was 74.1 cm3 including extraosseous bone expansion due to tumour growth, with a mean of volume of 21.4 mL of CaSO4/CaPO4 used to fill the intraosseous cavitary defects to restore normal bone anatomy. None of the lesions required additional internal fixation. The primary outcome measure, average time to full weight-bearing/full range of motion, was 11 weeks and 6 weeks for upper and lower extremity lesions, respectively. Secondary outcomes included tumour recurrence requiring reoperation in five patients and infection requiring reoperation in two patients.

CONCLUSION

This study demonstrates that CaSO4/CaPO4 is a viable option as a bone void filler in the reconstruction of cavitary defects following removal of primary benign bone tumours. CaSO4/CaPO4 provides sufficient bone regeneration early in the post-operative period to allow progression to full weight-bearing within weeks without the need for internal fixation. There were no graft-specific complications noted.

Evaluating Extended Curettage and Adjuvant Therapy Against Wide Resection and Reconstruction in the Management of Distal Radius Giant Cell Tumors: A Systematic Review and Meta-analysis

BACKGROUND

The management of distal radius giant cell tumors (GCTs) remains challenging, and the optimal approach is still a matter of debate. This systematic review and meta-analysis aimed to compare the outcomes of extended curettage and wide resection, the mainstays of treatment.

METHODS

Medline (via PubMed), Cochrane Library, Web of Science, Google Scholar, ClinicalTrials.gov, and Embase databases were searched for comparative studies that assessed extended curettage with adjuvant therapy and wide resection with reconstruction in patients with GCTs of the distal radius up to April 2023. Data were collected and analyzed on rates of local recurrence, metastasis, overall complications, and functional outcomes. The Newcastle-Ottawa scale was used to appraise the risk of bias within each study.

RESULTS

Fifteen studies (n = 373 patients) were included and analyzed. Patients who underwent curettage were more likely to develop recurrence (risk ratio [RR] = 3.02 [95% confidence interval; CI, 1.87-4.89], P < .01), showed fewer complications (RR = 0.32 [95% CI, 0.21-0.49], P < .01), and showed greater improvement in Visual Analog Scale and lower Disabilities of the Arm, Shoulder, and Hand scores (P < .00001) than those who underwent wide resection. No significant difference was found regarding metastasis (RR = 1.03 [95% CI, 0.38-2.78], P = .95).

CONCLUSIONS

Regarding the surgical approach to GCT of the distal radius, curettage with adjuvant therapy was associated with a higher likelihood of recurrence compared with wide resection with reconstruction. Nevertheless, the curettage approach resulted in significantly lower rates of operative complications, decreased pain scores, and better functional outcomes in comparison to the resection group.

Current Concepts in the Treatment of Giant Cell Tumor of Bone: An Update

Curettage is recommended for the treatment of Campanacci stages 1-2 giant cell tumor of bone (GCTB) in the extremities, pelvis, sacrum, and spine, without preoperative denosumab treatment. In the distal femur, bone chips and plate fixation are utilized to reduce damage to the subchondral bone and prevent pathological fracture, respectively. For local recurrence, re-curettage may be utilized when feasible. En bloc resection is an option for very aggressive Campanacci stage 3 GCTB in the extremities, pelvis, sacrum, and spine, combined with 1-3 doses of preoperative denosumab treatment. Denosumab monotherapy once every 3 months is currently the standard strategy for inoperable patients and those with metastatic GCTB. However, in case of tumor growth, a possible malignant transformation should be considered. Zoledronic acid appears to be as effective as denosumab; nevertheless, it is a more cost-effective option. Therefore, zoledronic acid may be an alternative treatment option, particularly in developing countries. Surgery is the mainstay treatment for malignant GCTB.

Extended curettage for tumour-induced osteomalacia in the bone

BACKGROUND

extended curettage is generally used to treat infiltrative bone tumours. However, the extent of the curettage performed in previous studies remains unclear. This study aimed to investigate the efficacy of extended curettage for bone tumour-induced osteomalacia.

METHODS

we included 12 patients with tumour-induced osteomalacia who underwent extended curettage at our hospital between 2000 and 2022. Extended curettage was applied in cases where tumour resection could cause functional impairment or necessitate complex reconstruction. We investigated patients' clinical and oncological outcomes.

RESULTS

patients had a mean age of 55 (24-81) years, and the median follow-up duration after surgery was 3.9 (1.0-14.0) years. The causative tumours were located in the pelvis and lumbar spine. Imaging revealed the tumours to be of the sclerotic, intertrabecular, lytic and mixed types. Intraoperative 3D fluoroscopy was used in 10 patients. Extended curettage with high-speed burring and adjuvant therapy with cauterization using an electric scalpel and ethanol resulted in a remission rate of 83%; no recurrence or metastasis was observed in cases of early postoperative biochemical remission. In cases where the causative tumour was at the lumbar spine and ischium close to the acetabulum, no postoperative biochemical remission was observed, and conservative treatment was continued. Except for one patient with a tumour in the lumbar spine, all patients could walk without a cane.

CONCLUSIONS

extended curettage for bone tumour-induced osteomalacia is oncologically and functionally favourable, especially in cases where resection of the causative tumour could cause functional impairment or necessitate complex reconstruction.

Intralesional curettage and surgical adjuvants in the treatment of giant cell tumor of bone: meta-analysis and systematic review

BACKGROUND

The ideal treatment for giant cell tumor of bone (GCTB) is still controversial. Various surgical adjuvants have been introduced following intralesional curettage to improve local control rates. However, findings from relevant studies are inconsistent, and no consensus has been reached. The purpose of this study is to determine what intraoperative adjuvant is effective in decreasing the recurrence of GCTB.

METHODS

We performed a systematic review and meta-analysis of articles published in the PubMed and Embase electronic databases which assessed the recurrence rate of GCTB following intralesional curettage with or without various surgical adjuvants. Two authors independently evaluated all publications. Meta-analysis was performed with Stata/MP (Version 17.0, StataCorp LLC, TX, USA) and Review Manager (RevMan, Version 5.4.1, The Cochrane Collaboration, 2020). Pooled risk ratio (RR) was used for analysis, with P values less than 0.05 considered statistically significant.

RESULTS

Twenty-four studies involving 2,579 patients were included in this analysis. The overall recurrence rates for patients treated with or without high-speed burring (HSB) are 11.9% (26/218) and 47.7% (92/193), respectively. The pooled RR for tumor recurrence is 0.33 (95% CI: 0.22 to 0.49, P<0.001). In the meanwhile, the overall recurrence rates for patients treated with or without chemical adjuvants are 23.5% (77/328) and 26.1% (73/280), respectively, with a pooled RR of 0.84 (95% CI: 0.63 to 1.10, P=0.89). Additionally, the overall recurrence rates for patients treated with or without polymethyl methacrylate (PMMA) are 20.4% (205/1,006) and 33.4% (314/939), respectively, with a pooled RR of 0.59 (95% CI: 0.50 to 0.69, P<0.001).

CONCLUSIONS

Intraoperative application of HSB or PMMA has an additional antitumor effect, while the use of phenol or H2O2 fails to make any significant difference (PROSPERO: CRD42022344262).

Aneurysmal bone cysts: A UK wide tumor center experience

BACKGROUND AND OBJECTIVES

This multicenter retrospective series of consecutive extra-spinal aneurysmal bone cysts aims to identify risk factors for treatment failure.

METHODS

Aneurysmal bone cysts treated within seven collaborating centers with over 12-months follow-up were eligible for inclusion. Survival analyses were performed to identify variables associated with recurrence using log-rank tests and Cox proportional hazard regression.

RESULTS

One hundred and fifteen (M:F 60:55) patients were included. Median age at presentation was 13 years and median follow-up was 27 months. Seventy-five patients underwent surgical curettage and 27% of these required further intervention for recurrence. Of the 30 patients who underwent biopsy with limited percutaneous curettage as initial procedure, 47% required no further treatment. Patients under 13 years (log-rank p = 0.006, HR 2.3, p = 0.011) and those treated who had limited curettage (log-rank p = 0.001, HR 2.7, p = 0.002) had a higher risk of recurrence/persistence.

CONCLUSIONS

There is a high risk of recurrence following surgical treatment for aneurysmal bone cysts and this risk is higher in young patients. However, the cyst heals in a substantial number of patients who have a limited curettage at the time of biopsy.

Improved Patient Outcomes with Electrocauterization Following Wedge Resection and Curettage for Ingrown Toenails: A Prospective Comparative Study

Background  Ingrown toenail is a common condition that results in chronic pain, recurrent infections, and difficulty in performing daily activities. Our aim is to compare two surgical methods for the treatment of ingrown toenails: wedge resection with curetting versus wedge resection curetting followed by electrocauterization of the nail bed. Methods  A prospective, comparative study that included 130 patients with ingrown toenails. All patients had stage II or III disease. We divided the participants into two groups according to the type of surgery and all patients were followed up for 6 months. The outcomes measured were the incidence of postoperative bleeding and infection, recovery time, patient satisfaction, and recurrence rate 6 months after surgery. Results  Of the 130 patients included, 59 (45.4%) underwent excision and curetting of the nail matrix (group 1) and 71 (54.6%) underwent excision, curetting, and electrocauterization of the nail matrix (group 2). The postoperative infection rates were 20.3 and 4.2% in the first and second groups, respectively ( p  = 0.004). Patient satisfaction was 76.3% among the first group, while 91.5% of patients in the second group were satisfied with the results of surgery. Six months postoperatively, recurrence rates were 25.4 and 4.2% in the first and second groups, respectively ( p  = 0.001). Conclusion  Wedge excision and curettage, followed by electrocauterization of the ingrown toenail is a safe treatment modality with a high success rate, that is evident by a lower recurrence rate, and greater patient satisfaction, with no effect on postoperative pain score or recovery time.

Diagnosis and Current Treatment of Aneurysmal Bone Cysts

The purpose of this review is to increase awareness about the evolution and development of current trends in the diagnosis and treatment of aneurysmal bone cysts (ABCs). ABCs are benign, but locally aggressive bone tumors that mainly affect children. ABCs comprise 1% of all primary bone tumors and occur most frequently during the first two decades of life. The diagnosis is made using a variety of imaging modalities and has the characteristic features of an expansile, radiolucent lesion that is often seen in the metaphyseal region of the bone and has fluid-fluid levels that are apparent on MRI. In the pediatric population, telangiectatic osteosarcoma and unicameral bone cyst (UBC) are the main differential diagnoses of an ABC. Giant cell tumors (GCTs) also include in differential diagnosis, which often manifest in patients older than 15 and do not penetrate the open physis although they develop after the physeal closure. Imaging alone cannot rule out telangiectatic osteosarcoma; therefore, a biopsy is recommended. A variety of treatment options have been described; traditionally, most patients are treated with curettage and bone grafting. Curettage alone, however, usually results in tumor recurrence following excision. A variety of adjuvants have been utilized with varying degrees of effectiveness to reduce the risk of local recurrence. When a cyst is in the pelvis, its location and size are such that surgery is a very risky option. Selective arterial embolization has significantly contributed to the development of effective treatments for these situations. Embolization or radiation, as well as denosumab therapy, are widely used as therapies for ABCs in anatomic locations where surgery would significantly increase morbidity.

Updates in the Management of Congenital Melanocytic Nevi

Congenital melanocytic nevi (CMN) carry an increased risk of melanoma and may be disfiguring, and consensus regarding treatment recommendations is lacking. While clinical monitoring is the standard of care, many caregivers are interested in its removal to prevent psychosocial burden or to decrease risk. Although melanoma can occur regardless of CMN removal, there are a variety of treatments that may offer improved cosmesis or local symptom control, including surgical excision, laser therapy, and other superficially destructive techniques. Regardless of the selected management, these patients are monitored for ongoing melanoma risk. An extensive discussion with families regarding the risks and benefits of observation versus active intervention is essential. To facilitate these discussions, we herein summarize current CMN management strategies and considerations.

Clinical efficacy and risk factors for suction curettage and hysteroscopy in patients with type I and II cesarean scar pregnancy

OBJECTIVE

To investigate the clinical efficacy and evaluate risk factors for suction curettage (SC) and hysteroscopy in the treatment of type I and II cesarean scar pregnancy (CSP).

METHODS

This was a retrospective study including 100 women diagnosed with type I/II CSP. Patients were treated with either ultrasound-guided SC (SC group) or hysteroscopy resection (surgery group). The success rates, mean operation time, hospitalization duration, hospitalization cost, risk factors, adverse events, and complications were analyzed.

RESULTS

The success rate of the SC and surgery groups were 85% and 100%, respectively, and the difference was statistically significant (P = 0.032). There was one case of type I CSP and eight cases of type II CSP that failed SC treatment. No failed cases were found in the surgery group. Analysis of the causes of treatment failure revealed that diameter of the gestational sac was a risk factor for SC failure (odds ratio, 19.66 [95% confidence interval {CI}, 1.70-227.72], P = 0.017). Comparing the clinical outcomes between the SC and surgery groups, although the mean operation time of the SC group was significantly shorter than the surgery group (15 [CI, 15-20] vs. 30 [CI, 27-40], P = 0.001), the cost and duration of hospitalization were significantly lower in the surgery group than that in the SC group. No significant differences were observed for adverse events and complications between the two groups (P > 0.05).

CONCLUSION

Hysteroscopy is an effective and economical method for treating type I/II CSP. Moreover, SC is not recommended for patients with type I/II CSP with a gestation age ≥8 weeks.

Post-traumatic Brodie's Abscess of the Tarsal Cuboid: A Case Report and Review of the Literature

Brodie's abscess of the tarsal cuboid is a relatively rare presentation of this disease. In this study, we present the case of a 20-year-old male with post-traumatic Brodie's abscess of the tarsal cuboid that was left untreated for three years after the traumatic episode (penetrating injury with a sharp piece of wood). The patient presented pain over the injured area, limping, while plain foot radiographs showed a small lytic cavitary area in the cuboid. The magnetic resonance imaging revealed the presence of the abscess in a 2-cm diameter cavity in the cuboid bone and chronic inflammation of the surrounding plantar musculature. The treatment regime included curettage of the cavity, debridement of the inflammatory tissues, and administration of antibiotics, according to the cultures harvested intraoperatively, for six weeks. During this period, symptoms completely resolved.

Primary Aneurysmal Bone Cyst in the Iliac Bone: A Case Report

Introduction

Aneurysmal bone cysts (ABCs) are non-neoplastic expansile, vascular, osteolytic benign tumors in the long bone, spine, and sternum. The location in the pelvis is sparse.

Case Report

A 12-year-old female presented with pain in her left pelvis for 6 months. On radiological examination, we found an expansile balloting lytic lesion involving almost the whole ilium and sparing the hip joint. There were multiple fluid levels seen on magnetic resonance imaging. The initial biopsy suggested ABC. Curettage and bone grafting were done along with electrocauterization and chemical cauterization. At 1-year follow-up, she is doing well without any complaints.

Conclusion

This case report demonstrates a rare ABC of the ilium that was managed with curettage and bone grafting.

Intraoperative cone-beam computed tomography-guided curettage for osteoid osteoma

Recently, cone-beam computed tomography (CBCT)-guided surgeries have been developed for bone and soft tissue tumors. The present study aimed to evaluate the efficacy of CBCT-guided curettage for osteoid osteoma. Our study population included 13 patients who underwent primary curettage for osteoid osteoma using intraoperative CBCT in a hybrid operating room between April 2019 and November 2022. We collected the following data: sex, age, follow-up period, symptom onset to time of surgery, tumor size and location, length of skin incision, operating time, radiation dose, recurrence, postoperative complications, and visual analog scale for pain during the last follow-up. There were 10 male and 3 female patients, and the mean age was 25.0 years (range, 9-49 years). The mean follow-up period was 10.6 months (range, 0.4-24.0 months). The locations of the tumors were the proximal femur in 6 patients, the acetabular region in 2 patients, and the ilium, tibial shaft, calcaneus, cuboid, and talus in 1 patient each. The mean time of symptoms onset to surgery was 18.7 months (range, 2.3-69.9 months). The mean maximum diameter of the tumor was 5.9 mm (range, 3.5-10.0 mm). The mean length of the skin incision was 2.2 cm (range, 1.5-3.5 cm). The mean operating time was 96.9 minutes (range, 64-157 minutes). The mean dose of radiation was 193.2 mGy (range, 16.3-484.0 mGy). No recurrences, postoperative complications, and reoperation were observed in this study. All the patients reported 0 mm on the visual analogue scale for pain on the last follow-up. CBCT-guided curettage for osteoid osteoma was minimally invasive and reliable. This procedure can be effective for the treatment of lesions found in deep locations such as the pelvic bone and proximal femur or an invisible lesion that cannot be detected by regular fluoroscopy.

Asymptomatic fetal bone retention detected 12 years after termination of pregnancy: case report

Intrauterine retention of fetal bone fragments is a rare complication that can be seen after pregnancy termination, especially in advanced gestational weeks. Here, we present a case of intrauterine fetal bone retention detected during routine gynecological examination in an asymptomatic woman whose pregnancy was terminated 12 years ago. Under local anesthesia and ultrasound guidance, the fetal bone was removed with a grasper. This case report highlights the importance of post-curettage ultrasound examination to ensure that no fetal tissue is left behind after termination of pregnancy.

Late recurrence in surgically managed pediatric atypical mycobacterial lymphadenitis: A case report and review of the literature

Objective

The purpose of this study is to identify existing literature on recurrent atypical mycobacterial cervicofacial lymphadenitis to augment our understanding of a unique patient who presented to our tertiary-care center 5-years posttreatment with recurrence following curettage.

Data Sources

OVID Medline, Scopus, and Web of Science.

Methods

A literature search was conducted yielding 49 original articles which were screened twice by two independent reviewers resulting in 14 studies meeting inclusion criteria for data extraction using Covidence software. Two independent reviewers extracted data on recurrence of atypical mycobacterial cervicofacial lymphadenitis and consensus was reached on data points from all included studies.

Results

This study illuminated the paucity of recurrence reporting in the literature regarding atypical mycobacterial lymphadenitis. Sixteen studies identified in our review included discussions on recurrence with few elaborating beyond the rate of recurrence to describe their management. Fourteen out of sixteen studies provided recurrence rates for their cohort, 11 out of 14 specified the initial treatment modality, and only five out of eight studies that described initial treatment with surgery differentiated recurrence rates between complete and incomplete excision. The mean length of follow-up in the included studies was 20 months. There was one previously reported case of late recurrence at 5-years.

Conclusions

We identified few reports that discussed the management of recurrence of atypical mycobacterial cervicofacial lymphadenitis. There was minimal data on recurrence rates between surgical treatment modalities. The case discussed in our study showcases that treatment with curettage has the potential to present with late recurrence.

Association of menstrual blood volume and reproductive outcomes in patients with caesarean scar pregnancy managed using uterine artery embolization and curettage

This study aimed to assess the association of menstrual blood volumes (MBV) and reproductive outcomes in patients after uterine artery embolization (UAE) combined with curettage for caesarean scar pregnancy (CSP). This retrospective observational study enrolled women who underwent UAE plus curettage for CSP at the Interventional Department of Henan Provincial People's Hospital between December 2012 and December 2017. The primary outcome was pregnancy rate and the secondary outcomes were live birth rate (LBR) and interpregnancy interval. This study finally included 37 women (16 women with normal MBV and 21 women with decreased MBV) with pregnancy intention after UAE plus curettage for CSP. The pregnancy rate in women with normal MBV was higher than those with decreased MBV (81.3% vs. 47.6%; P = 0.048). There were no differences between the two groups regarding the interpregnancy interval (18.4 ± 8.7 vs. 22.2 ± 10.0 months, P = 0.233), and LBR (63% vs. 38%, P = 0.191). In conclusion, Women with normal MBV after UAE combined with curettage for CSP management might have a higher pregnancy rate compared with patients with decreased MBV, but there were no differences in LBR between the two groups.

Pulmonary embolism after diagnostic curettage in patient with adenomyosis and hysteromyoma: A case report and brief review of literature

RATIONALE

Pulmonary embolism (PE) is a common cause of cardiovascular death whose major acquired risk factors include postoperative states, pregnancy, malignancy, and age. We report a case of PE that occurred after diagnostic curettage for abnormal uterine bleeding, with a medical history of adenomyosis and hysteromyoma.

PATIENT CONCERNS AND DIAGNOSES

A 31-year-old Han Chinese female was referred to our hospital with menstrual disorders, increased menstrual flow, and severe anemia. After admission, the patient was treated with a blood transfusion, iron supplementation, and erythropoietin, and diagnostic curettage was performed the following day. On the first postoperative day, the patient developed pulmonary embolism with dyspnea and fever diagnosed by CT pulmonary angiography and significantly elevated D-dimer.

INTERVENTIONS AND OUTCOMES

Molecular weight heparin was administered for PE for 2 weeks, dyspnea was relieved significantly after 2 days of treatment and the uterine bleeding did not increase; and gonadotropin-releasing hormone agonists were administered for adenomyosis after 1 week of anticoagulant therapy to reduce bleeding. We followed up for 6 months, and the patient had no recurrence of thrombosis and uterine bleeding had improved.

CONCLUSION

We speculate that the occurrence of pulmonary embolism was closely related to adenomyosis, hysteromyoma, and curettage in this patient. Treating the presence of both menstrual bleeding and thromboembolism is challenging, and careful management is necessary to avoid therapeutic contradictions.

Giant Cell Tumor: A Case Series of Seven Patients with GCT at Atypical Sites

Introduction

Giant cell tumor (GCT) represents 5% of all primary bone tumors and 20% of biopsy analyzed benign tumors. More than half of these lesions occur in the 3rd and 4th decades of life. There is no absolute treatment method selection. Techniques ranging from intralesional curettage to wide resection can be used. Goal is to eradicate the tumor, preserve limb function, and prevent local recurrence and distant metastasis.

Case Report

We are presenting seven cases of GCT at five different and rare sites involving tibia, calcaneum, metatarsal, proximal humerus, and clavicle with tumor being limited to bone in all seven cases not involving the soft tissue. There were three male patients and four female patients. Six patients underwent intralesional curettage using high-speed burr and curette, along with adjuvant irrigation with hydrogen peroxide and normal saline followed by polymethyl methacrylate reconstruction. One patient with GCT clavicle underwent wide resection.

Results

In all seven cases, we were able to able to remove the tumor completely. Six patients had a gradual and complete recovery with return to near normal activity within 6 month-1 year after surgery. One patient with proximal humerus GCT had a recurrence which got resolved with injection denosumab. All patients have been followed up for a minimum duration of 2 years.

Conclusion

Intervention in the early stages can avoid radical procedures such as wide local excision or amputation. We recommend aggressive surgical approach with close follow-up to detect recurrence if any, at an early stage.

Curettage and colour-A technique for defining tumour depth on the ear in the Mohs and non-Mohs setting

For tumours of the ear that are suspected to involve auricular cartilage, precise definition of the extent of involved deep margin can be difficult. As large resections of cartilage can be cosmetically disfiguring with limited repair options, we propose a simple and effective technique to facilitate a targeted deep margin resection using a curette and a surgical marking pen.

Pregnancy Rates after Hysteroscopic Endometrial Polypectomy versus Endometrial Curettage Polypectomy: A Retrospective Study

Background and Objectives: A relationship between endometrial polypectomy and in vitro fertilization (IVF) pregnancy outcomes has been reported; however, only a few studies have compared polyp removal techniques and pregnancy rates. We investigated whether different polypectomy techniques with endometrial curettage and hysteroscopic polypectomy for endometrial polyps affect subsequent pregnancy outcomes. Materials and Methods: Data from 434 patients who had undergone polypectomy for suspected endometrial polyps using transvaginal ultrasonography before embryo transfer in IVF at four institutions between January 2017 and December 2020 were retrospectively analyzed. Overall, there were 157 and 277 patients in the hysteroscopic (mean age: 35.0 years) and curettage (mean age: 37.3 years) groups, respectively. Single-blastocyst transfer cases were selected from both groups and age-matched to unify background factors. Results: In the single-blastocyst transfer cases, 148 (mean age: 35.0 years) and 196 (mean age: 35.9 years) were in the hysteroscopic and curettage groups, respectively, with the 148 cases matched by age. In these cases, the pregnancy rates for the first embryo transfer were 68.2% (odds ratio (OR): 2.14) and 51.4% (OR: 1.06) in the hysteroscopic and curettage groups, respectively; the resulting OR was 2.03. The pregnancy rates after up to the second transfer were 80.4% (OR: 4.10) and 68.2% (OR: 2.14) in the hysteroscopic and curettage groups, respectively, in which the OR was 1.91. The live birth rates were 66.2% (OR: 1.956) and 53.4% (OR: 1.15) in the hysteroscopic and curettage groups, respectively, in which the odds ratio was 1.71. These results show the effectiveness of hysteroscopic endometrial polypectomy compared to polypectomy with endometrial curettage. No significant difference was found regarding the miscarriage rates between the two groups. Conclusions: Hysteroscopic endometrial polypectomy resulted in a higher pregnancy rate in subsequent embryo transfer than polypectomy with endometrial curettage. Therefore, establishing a facility where polypectomy can be performed hysteroscopically is crucial.

Aneurysmal Bone Cyst of the Pelvis in Children and Adolescents: Effectiveness of Surgical Treatment with Curettage, Cryotherapy and Bone Grafting

BACKGROUND

Aneurysmal bone cysts (ABCs) are benign but locally aggressive cystic lesions of the bone. Pelvic ABCs are extremely rare and hard to treat due to their high risk of local recurrence and the tough access to pelvic bones.

METHODS

In this retrospective study, we evaluated pediatric cases with pelvic ABC treated with curettage, cryotherapy and bone grafting treated in our institution between 2016 and 2022. Complications were recorded, as well as local recurrences. Patients' post-operative functionality was assessed with the MSTS score.

RESULTS

Fourteen consecutive cases were included in our study. Their mean age at surgery was 13.5 years. The mean lesion size was 55 mm. The mean follow-up was 38 months. Two cases (11.8%) had local recurrences, which were successfully treated with further curettage. At their latest FU, 13 cases were continuously disease free (CDF), and one had no evidence of disease (NED). Only one case had a post-operative compilation (wound dehiscence). Patients' mean post-operative MSTS score was 29.6.

CONCLUSIONS

Pelvic ABCs are a challenge, even for the most experienced orthopedic surgeon. Our study suggests that the association of an accurate curettage, intraoperative cryotherapy and bone grafting can be a reliable and effective therapeutic option for large-sized ABCs of the pelvis.

Radicular Cyst Presenting in a Female Child: A Case Report

A radicular cyst, also known as a periapical cyst or root end cyst, is usually associated with permanent dentition and its association with deciduous teeth is an infrequent phenomenon. Radicular cyst typically arises from inflammation of the pulp and periapical tissues of a non-vital tooth. This article presents a case report of a six-year-old female with an apical periodontal cyst associated with deciduous and permanent teeth in the maxillary posterior region of the jaw. Early diagnosis of the lesion might have resulted in a conservative treatment plan. This text's purpose is to emphasize the pedodontist's role in the early analysis of such lesions.

The Rare Occurrence of Giant Cell Tumor of the Proximal Tibia With Pathological Fracture in an Elderly Male: A Case Report

Giant cell tumor of the bone (GCTB) is a benign bone tumor that can occasionally progress to malignancy, usually in chronic cases. It is a common benign and aggressive bone tumor that affects patients aged between 20 and 45 years. The most common location is the knee joint. It manifests as a painless or occasionally painful swelling over the affected area. A case of giant cell tumor (GCT) of the proximal tibia in a 72-year-old male is reported here, which was difficult to diagnose as it is rarely found in the geriatric age group. The patient came with a chief complaint of pain and swelling over his left knee for two months with a history of trauma to the knee a couple of times. On clinical examination, the patient had grade 3 tenderness and swelling on the anterolateral aspect of the knee extending toward the proximal tibia. The swelling was well-defined, smooth, firm, and uniform in consistency with dimensions of 15 cm × 12 cm. The swelling was moveable sideways, and the movement of the knee suggested that it was not attached to the underlying bone. As per the age and history of the rapid-growing lesion, we suspected malignancy, but clinical findings were pointing toward benign tumor. X-ray of the affected knee was done, which revealed a soft tissue mass with the involvement of the bone. Magnetic resonance imaging (MRI) of the knee revealed a soft tissue mass with the cortical breach. An open biopsy was done for the confirmation of the diagnosis, which was later reported and confirmed as a giant cell tumor of the proximal tibia. As bone tumor is associated with a cortical breach and pathological fracture, it was classified under Campanacci grade 3, for which an en bloc resection and open reduction and internal fixation with plate osteosynthesis with bone cementing and bone grafting were done followed by knee bending physiotherapy and gradual weight-bearing. Finally, the knee function was improved with pain relief.

Treatment of Recurrent Giant Cell Tumor of Bones: A Systematic Review

The giant cell tumor of bones (GCTB) is a benign bone tumor with high postoperative recurrence potential. No specific treatment protocol has been developed to date in case of tumor recurrence, and the kind of re-operative surgery depends upon the surgeon's preferences. The aim of this systematic review is to determine the second recurrence rate and the respective functional results of the available treatment options applied to recurrent GCTB. Medline/PubMed and Scopus were searched to identify articles published until March 2023. Twelve studies fulfilled the inclusion criteria, comprising 458 patients suffering from recurrent GCTB. The overall incidence of second recurrence was 20.5%, at a mean interval of 28.8 months after the first surgery, and it was more evident after intralesional curettage (IC) surgery than en-bloc resection (EBR) (p = 0.012). In the IC group of patients, the second recurrence rate was lower and the functional outcome was greater when polymethylmethacrylate cement (PMMAc) was used as an adjuvant instead of bone grafting (p < 0.001 for both parameters). Reconstruction of the created bone defect after EBR with a structural allograft provided a better outcome than prosthesis (p = 0.028). According to this systematic review, EBR (first choice) and IC with PMMAc (second choice) are the best treatment options for recurrent GCTB.

Long-term Follow-up Results of Primary Canaliculitis Patients

Objectives

To evaluate the demographic characteristics, clinical presentation, microbiologic profile, and treatment results of patients with primary canaliculitis.

Materials and Methods

Patients diagnosed and treated for primary canaliculitis between May 2014 and May 2021 were analyzed retrospectively.

Results

There were 26 patients with primary canaliculitis, including 17 females (65.4%) and 9 males (34.6%) with a mean age of 50.6±16.4 years (range: 9-80 years). Canaliculitis affected the right eye in 11 patients, the left eye in 13 patients, and bilateral involvement was seen in 2 patients. Inferior canaliculus involvement was more frequent (73%). The most common complaint was epiphora (46.1%). Five patients (19.2%) were wrongly diagnosed as chronic conjunctivitis. The time interval between the beginning of symptoms and canaliculitis diagnosis was 18.2±14.3 months (range: 1-60 months). Canaliculotomy and curettage of canalicular content with dacryolith removal were performed in 23 patients. After surgery, antibiotic irrigation of the canaliculus was added to the treatment regimen in 12 of these 23 patients. Intracanalicular antibiotic therapy was administered to the remaining 3 patients. The most cultured organism was Actinomyces (6 patients). Gemella (1 patient), Porphyromonas (1 patient), Candida parapsilosis (1 patient), Citrobacter koseri (1 patient) were also grown in culture. The follow-up time of patients was 26.2±23.7 months (range: 6-83 months). All symptoms and findings resolved in all patients in one month. In two patients, recurrence occurred at 4 and 16 months after surgical treatment. With appropriate treatment, no further recurrence was seen in either patient over 24-month follow-up. One patient presented with iatrogenic canaliculus blockage during follow-up.

Conclusion

Primary canaliculitis is often overlooked and can be misdiagnosed. The most common symptom was epiphora. All patients with epiphora and chronic conjunctivitis should be examined carefully for canaliculitis.

A Rare Giant Cell Tumour in the Distal Radius of a Seven-Year-Old Girl: A Case Report

A giant cell tumour (GCT) is a benign and locally aggressive tumour that is usually observable in a skeletally mature patient involving the end of long bones. The reported incidence of this tumour in a skeletally immature patient is extremely rare. However, we report one such case in the distal radius of a seven-year-old female patient. Having presented with painful swelling of the right distal forearm, she underwent clinical and radiological examination, and a diagnosis of distal radius GCT was made. The tumour was treated with curettage, fibular graft, and synthetic bone graft. This case report shows the importance of including GCT in children as a differential diagnosis. This tumour may have a good prognosis if diagnosed and treated early.

A Case Report of Giant Aneurysmal Bone Cyst of Distal Tibia with a Non-healing Fungating Mass and its Management in a 30-year-old Male

Introduction

Aneurysmal bone cyst (ABC) is a benign, expansible, non-neoplastic tumor of usually long bones and is identified by blood vessels and spaces that are most often differentiated by fibrous septae. It is challenging to treat these rare, giant ABCs as they have a damaging effect on the bones and compress the nearby structures, especially in load-bearing bones of the body.

Case Report

We report a case of a giant ABC in the distal tibia one-third with soft tissue component of a 30-year-old male. The patient presented to our outpatient department with complaints of pain and swelling over left ankle for 1 year. The size of the swelling was 15 cm × 10 cm × 10 cm over medial aspect of ankle with 3 discharging sinuses which present over swelling. His blood parameters were suggestive of low hemoglobin count. X-rays showed cystic lesions over medial aspect of left ankle. Computed tomography scan and magnetic resonance imaging reports were suggestive of ABC.

Conclusion

Our case report is unique as it reminds us that when presented with a case of ABC, excision of fungating soft tissue with curettage followed by cementing can be a preferable and better treatment option. ABC was extensively curetted out, the formed cavity was packed with bone cement, and fixation with 3 cortico cancellous screws was carried out. At 4-month follow-up, the lesion had receded, and the patient was walking without pain and any deformity. We suggest that this method of treatment is beneficial for ABC at this site and at this age.

A Rare Case of Cemento-Ossifying Fibroma: A Case Report

Benign fibro-osseous lesions are a group of pathological conditions characterized by the replacement of normal bone with cellular fibrous connective tissue that undergoes mineralization. The most common types of benign fibro-osseous lesions include fibrous dysplasia, ossifying fibroma, and osseous dysplasia. However, diagnosing these lesions can be challenging due to their overlapping clinical, radiological, and histological features, which can cause a diagnostic dilemma for surgeons, radiologists, and pathologists. One rare type of benign fibro-osseous lesion is the cemento-ossifying fibroma (COF), which is a definitive form of a benign fibro-osseous tumor that affects the craniofacial region, particularly the jaws (70%). Here, we present a case of COF in a 61-year-old female patient in the maxillary anterior region. Due to a clear distinction between the lesion and healthy bone, the lesion was treated with conservative surgical excision followed by curettage and primary closure. However, differential diagnosis of COF can be highly challenging for clinicians due to its overlapping features with other fibro-osseous lesions like Paget's disease and fibrous dysplasia. Ossifying fibroma and fibrous dysplasia often present a histopathological, clinical, and radiological overlap. The post-operative follow-up after eight months was unpredictable, with a radiological picture showing the increased thickness of the frontal bone, parietal bone, and maxilla with obliteration of marrow spaces, alteration of the trabecular pattern with a cotton wool/ground glass appearance, and reduced maxillary sinus space. Proper evaluation and diagnosis of fibro-osseous lesions are necessary before arriving at a final conclusion. Cemento-ossifying fibroma in the maxillofacial skeleton is uncommon, and after eight months, the recurrence rate is rare. This case highlights the importance of considering COF as a differential diagnosis for fibro-osseous lesions in the maxillofacial region and the necessity for proper evaluation and diagnosis to determine the appropriate treatment plan and prognosis. In summary, the diagnosis of benign fibro-osseous lesions can be challenging due to their overlapping features, but early diagnosis and proper evaluation are essential for successful treatment outcomes. COF is a rare type of benign fibro-osseous lesion where other fibro-osseous lesions in the maxillofacial region should be considered as a differential diagnosis, and the necessary steps should be taken to confirm the diagnosis before arriving at a final conclusion.

Curettage or Resection? A Review on the Surgical Treatment of Low-Grade Chondrosarcomas

Introduction Low-grade chondrosarcomas (LG-CS), including atypical cartilaginous tumors (ACT), are locally aggressive lesions. The focus of the discussion sits on the differential diagnosis between benign lesions or aggressive cartilaginous tumors and on their treatment: intralesional curettage or wide resection. This study presents the results obtained in the surgical treatment of 21 cases of LG-CS. Methods This retrospective study includes 21 consecutive patients from a single center with LG-CS who underwent surgery from 2013 to 2021. Fourteen were located in the appendicular skeleton, and seven in the axial (shoulder blade, spine, or pelvis). Mortality rate, recurrence, metastatic disease, overall survival, recurrence-free survival, and metastatic disease-free survival were analyzed for each type of procedure and each disease location. Operative complications and residual tumors were also recorded in cases where resection was performed. Survival was calculated using the Kaplan-Meier method. Results Thirteen patients underwent intralesional curettage (11 appendicular and 2 axial lesions), and eight underwent wide resection (5 axial and 3 appendicular). There were six recurrences during the follow-up, 43% of the axial lesions recurred, rising to 100% in axial curetted ones. Appendicular LG-CS recurred in 21% of cases, and only 18% of curetted appendicular lesions were not eradicated. The overall survival for the entire follow-up is 90.5%, and the 5-year survival rate is 83% (12 patients have adequate follow-up). Recurrence-free and metastasis-free survival were higher in resection cases, with 75% and 87.5%, vs. curettage 69.2% and 76.9%, respectively. In 9% of cases, the preoperative biopsy was inconsistent with the pathology of the surgical specimen. Discussion LG-CS and ACT are described as having high survival and low potential for metastatic disease. For this reason, these lesions are subject to a change in treatment philosophy to reflect these characteristics. Intra-lesional curettage is advocated as a less invasive technique for eradicating atypical cartilage tumors and has fewer and less severe complications, which was in accordance with our findings. Diagnosis, however, is challenging; misgrading is frequent and should be considered. Because of this risk of under-treating higher-grade lesions, some authors still defend wide-resection as the treatment of choice. We observed a trend towards longer survival, less recurrence, and metastatic disease with wide resection. Metastatic disease was higher than expected, present in 19% of cases, and always associated with local recurrence. Conclusion LG-CS is still a diagnostic and treatment challenge; patient selection is fundamental. Overall survival is high, independent of treatment choice or lesion location. We found a higher rate of metastatic disease than described in the literature; this, coupled with a misgrading rate of 9%, reflects the difficulty of preoperative diagnosis and the risk of treating high-grade chondrosarcomas as a low-grade lesion. More studies should be carried out with larger samples to obtain statistically robust results.

Effectiveness of Nitrous Oxide versus Pethidine/Midazolam for Pain Relief in Minor Gynecological Operative Procedures: A Randomized Controlled Trial

Aim and Objective: To compare the analgesic effectiveness of the patient-controlled inhaled nitrous oxide (Entonox^®) with intravenous opioids (pethidine/midazolam) in reducing pain during minor gynecological operative procedures, including manual vacuum aspiration (MVA), fractional curettage and dilatation and curettage. Materials and Methods: Patients undergoing minor gynecological procedures from August 2021 to December 2022 were randomized to receive nitrous oxide or intravenous pethidine (50-75 micrograms) plus midazolam (2 mg). Pain scores during and post-procedure, satisfaction level, and side effects were assessed and compared. Results: A total of 106 patients met the inclusion criteria, including 53 in the pethidine/midazolam group and 53 in the nitrous oxide group. Baseline characteristics were comparable (p-value > 0.05). Pain scores during, immediately and 30 min after procedures were not significantly different in two groups (4.94 ± 3.15, 2.74 ± 2.57, 1.58 ± 2.13 vs. 5.47 ± 2.80, 2.98 ± 2.70, 1.64 ± 2.70; p-value: 0.174, 0.634, 0.889, for pethidine/midazolam vs. nitrous oxide group, respectively. Satisfaction scores were comparable in both groups (p-value > 0.05). However, the rate of side effects was significantly lower in the nitrous oxide group (3.8% vs. 28.3%; p-value 0.001). Additionally, the discharge scores showed a significantly faster recovery time in the nitrous oxide group at 60 and 90 min after the procedure; median (IQR): 10 (9-10) vs. 9 (8-10) and 10 (10-10) vs. 10 (8.5-10); p-value 0.002 and 0.029, respectively). Conclusions: Nitrous oxide is as effective as pethidine/midazolam for pain relief in minor gynecological operative procedures but associated with significantly lower side effects and significantly faster recovery time.

Surgical treatment of a rare case of atypical polypoid adenomyoma of the uterus in a menopausal patient: a case report

Atypical polypoid adenomyoma is a rare benign tumor of the uterus that usually affects women of reproductive age and has an increased risk of progression into endometrial cancer. The pathogenetic mechanism has not been completely clarified. Due to the rarity of the tumor, current experience regarding the diagnostic and therapeutic approach is limited. For menopausal patients, hysterectomy seems to be the main treatment option. Our case concerns an asymptomatic menopausal patient with a vaginal delivery in her obstetric history and no hereditary history of gynecological cancer who came to the outpatient clinic for a gynecological examination. Transvaginal ultrasound revealed the presence of a large, round solid mass with increased vascularity within the endometrial cavity. A diagnostic dilation and curettage of the endometrium was performed. Histological examination of the endometrial biopsy showed an atypical polypoid adenomyoma, and it was decided to perform a total abdominal hysterectomy with bilateral adnexectomy. Histological examination of the surgical specimen of the uterus revealed no residual disease, no coexisting foci of atypical endometrial hyperplasia or endometrial cancer. The postoperative course was uneventful. The patient remains to this day under regular follow-up. The present case report highlights the significant difficulties involved in the preoperative diagnosis of atypical polypoid adenomyoma of the uterus and the difficult differential diagnosis from atypical endometrial hyperplasia and endometrial cancer, particularly in menopausal patients. At the same time, it is pointed out that despite its rarity, the early diagnosis of atypical polypoid adenomyoma, especially in young women, must be the main concern of the modern gynaecologist, in order to design the optimal treatment aimed at preserving fertility while avoiding the risk of recurrence of damage or malignant progression into endometrial cancer.

Application of NGS molecular classification in the diagnosis of endometrial carcinoma: A supplement to traditional pathological diagnosis

OBJECTIVE

This study aims to demonstrate the advantages of NGS molecular classification in EC diagnosis and to assess whether molecular classification could be performed on curettage specimens and its concordance with subsequent hysterectomy specimens.

METHODS

80 patients with hysterectomy specimens and 35/80 patients with paired curettage specimens were stratified as POLE mut, MSI-H, TP53 wt, or TP53 abn group by NGS panel. Histotype, tumor grade, IHC results, and other pathological details were taken from original pathological reports.

RESULTS

The correlation analysis of 80 patients with hysterectomy specimens between NGS molecular classification and clinicopathological characters displayed that the POLE mut group was associated with EEC (87.5%) and TP53 abn subtype was correlated to a later stage (Stage II-IV, 47.6%), G3 (76.2%), serous histology (61.9%) and myometrial invasion ≥50% (47.6%). A favorable concordance (31/32, 96.9%) was shown in MSI analysis and MMR IHC results, and the agreement rate of p53 IHC and TP53 mutation was 81.5% (53/65). Compared with the p53 IHC abnormal group, the TP53 mutation group had a higher correlation with high-risk factors. A high level of concordance (31/35, 88.0%) of NGS molecular classification was achieved between curettage specimens and hysterectomy specimens while grade and histotype (including unclassified group) from curettage specimens and hysterectomy specimens showed only moderate levels of agreement, 54.3% (19/35) and 68.6% (24/35), respectively.

CONCLUSION

NGS molecular classification achieved on curettage samples showed high concordance with the final hysterectomy specimens, demonstrating superior to the conventional pathological assessment of grade and histotype and potential utilization in clinical practice.

The treatment of aneurysmal bone cysts

PURPOSE OF REVIEW

Aneurysmal bone cysts are rare, locally aggressive bone tumors. Optimal treatment of ABCs is still matter of debate as therapies including sclerotherapy, selective arterial embolization and systemic treatment with denosumab are increasingly utilized, in addition to or instead of traditional curettage. The purpose of this review is to discuss current concepts and difficulties in diagnosing and treating primary ABCs, based on latest available literature.

RECENT FINDINGS

In diagnostics, multiple new fusion partners of USP-6 have been described on next-generation sequencing specifically for primary ABCs. In a recent systematic review, failure rates of percutaneous injections and surgery were comparable. In a literature review, the use of denosumab seemed effective but resulted in multiple cases of severe hypercalcemia in children.

SUMMARY

Accurately diagnosing primary ABC is crucial for treatment decisions. Curettage remains a valid treatment option, especially with adjuvant burring, autogenous bone grafting and phenolization. Percutaneous sclerotherapy represents a solid alternative to surgery, with polidocanol showing good results in larger studies. Systematic therapy with denosumab exhibits favorable results but should be reserved in the pediatric population for unresectable lesions, as it may result in severe hypercalcemia in children. When selecting a treatment option, localization, stability and safety should be considered.

Predictive factors analysis of cesarean scar pregnancy treated by local injection of Lauromacrogol combined with curettage

To explore factors related to local injection of Lauromacrogol combined with curettage in the treatment of cesarean scar pregnancy. A total of 24 successful and 8 unsuccessful cases were included. The age, gravidity, parity, times of cesarean section, interval from the last cesarean section, preoperative human chorionic gonadotropin (HCG), HCG on the first day after operation, decreasing rate of HCG on the first day after operation, average diameter of gestational sac, and preoperative vaginal bleeding days were analyzed. There were no significant differences of age, gravidity, parity, previous cesarean section times between groups. The differences of preoperative HCG, HCG on the first day after operation, the decreasing rate of HCG, gestational sac diameter, preoperative vaginal bleeding days were statistically significant between groups. The interval from the last cesarean section and the decreasing rate of HCG were protective factors, while the mean diameter of gestational sac and period of vaginal bleeding before operation were risk factors for the success of the treatment. The mean diameter of gestational sac owned the best predictive value.

Comparison of prognosis of patients with endometrial cancer after hysteroscopy versus dilatation and curettage: A multicenter retrospective study

Introduction

Hysteroscopy is a useful procedure for diagnosing endometrial cancer. There is controversy regarding whether hysteroscopy affects the prognosis of endometrial cancer by prompting cancer cell into intraperitoneal dissemination. Our purpose was to confirm whether hysteroscopy could be a risk factor of the tumor stage, recurrence and survival rate of endometrial cancer.

Methods

This multicenter retrospective study included all consecutive patients who had endometrial carcinoma diagnosed preoperatively with hysteroscopy and directed endometrial biopsy (HSC, group A) and dilatation and curettage (D&C, group B) between February 2014 and December 2018 at the Fujian Provincial, China. We compared the demographic feature, clinical characteristics and prognosis between the two groups.

Results

A total of 429 patients were included in the study (Group A, n = 77; Group B, n = 352). There was no significant difference between their baseline characteristics [including age, BMI, histological type and International Federation of Gynecology and Obstetrics (FIGO) stage]. By comparing several pathological conditions that may affect prognosis, there were no significant differences between the two groups in the peritoneal cytology, depth of myometrial invasion, the positivity of lymph nodes, lymphovascular space invasion and paraaortic lymph node dissection. Finally, no significant difference was found between the two groups in overall survival (OS) (P = 0.189) or recurrence free survival (RFS) (P = 0.787).

Conclusion

Under certain inflation pressure and distension medium, hysteroscopic examination and lesion biopsy ensure the safety and have no adverse effects on prognosis compared to conventional curettage.

Unicystic ameloblastoma - A case series

Ameloblastoma is a benign, locally aggressive neoplasm that constitutes about 1-3% of the tumors of the jaw. Wide surgical excision with adequate safe margin is the most common treatment of choice. The study aimed to manage cases with unicystic ameloblastoma while preserving the continuity of the mandible (without resection). This article presents a series of cases ranging from 18 to 40 years old patients of both sexes with unicystic ameloblastoma, especially in the mandible showing more male predilection than female. All the cases presented in this article were treated by enucleation and curettage. None of the patients presented post-operative paresthesia. None of the cases went in for resection. Post-operative recovery was uneventful in all the patients. All the patients were followed up for a period of 3.5-5 years. None of the cases reported recurrence at the date of publication.

Clinical efficacy and safety analysis of different treatment options for Cervical pregnancy

OBJECTIVE

To compare the efficacy and safety of different treatment options for cervical pregnancy (CP).

MATERIALS AND METHODS

A total of 74 patients diagnosed with CP at Hunan Provincial Maternal and Child Health Care Hospital between January 2016 and September 2022 were retrospectively analyzed. Among them, 31 were treated with uterine artery embolization (UAE) followed by hysteroscopic curettage, 34 were treated with hysteroscopic curettage alone, and nine were treated with high-intensity focused ultrasound (HIFU) followed by hysteroscopic curettage. Medical records and pregnancy outcomes were analyzed.

RESULTS

There were no significant differences in age, gravidity, parity, abortion, or preoperative hemoglobin levels among the patients in the three groups; however, significant differences in gestational age, gestational sac diameter, preoperative β-hCG, and presence of cardiac pulsation were observed (p < 0.05). After treatment, there was no conversion to laparotomy, and the uterus was preserved in all patients. Significant differences in blood loss during curettage, hospitalization costs, hospital days, menstrual recovery interval, β-hCG decline rates, retained products of conception, and intrauterine adhesions rate among the three groups were observed (p < 0.05). There were no significant differences in the placement of the uterine Foley balloon, effective curettage rate, pre-and postoperative hemoglobin decline, live birth rate, or proportion of subsequent pregnancies among the three groups.

CONCLUSION

Our results showed that hysteroscopic curettage, HIFU, and UAE followed by hysteroscopic curettage are safe and effective for treating patients with CP. Compared with the UAE, HIFU has the advantages of lower hospitalization costs, shorter hospital stays, and shorter menstrual recovery intervals.

Effectiveness, complications, and reproductive outcomes after cesarean scar pregnancy management: a retrospective cohort study

BACKGROUND

There is a dramatic rise in cesarean deliveries worldwide, leading to higher complication rates in subsequent pregnancies. One of these complications is a cesarean scar pregnancy. During the last decades, treatment options for cesarean scar pregnancies have changed, and less invasive interventions have been employed to preserve fertility and reduce morbidity. However, the optimal treatment approach and the influence of various treatments on reproductive outcomes have to be determined.

OBJECTIVE

This study aimed to evaluate the short- and long-term outcomes after cesarean scar pregnancy management.

STUDY DESIGN

We conducted a retrospective cohort study of women determined to have a cesarean scar pregnancy from 2010 to 2021 at a tertiary referral center, the Amsterdam University Medical Center, in the Netherlands. Outcomes of the following management strategies were compared: expectant management, methotrexate, curettage with temporary cervical cerclage, or a laparoscopic niche resection. We performed a curettage if the cesarean scar pregnancy did not cross the serosal line of the uterus, and a laparoscopic niche resection was performed if the cesarean scar pregnancy crossed the serosal line. The main outcomes were treatment efficacy and time to subsequent ongoing pregnancy or pregnancy leading to a live birth.

RESULTS

Of the 60 included women, 5 (8.3%) were managed expectantly, 8 (13.3%) were treated with methotrexate, 31 (51.8%) were treated with a curettage, and 16 (26.7%) with a laparoscopic niche resection. The groups were not comparable. The gestational age and human chorionic gonadotropin levels were generally higher in women who received methotrexate or a laparoscopic niche resection. Additional treatment in the conservative group was needed for 4 (80%) women after expectant management and for 7 (87.5%) women after methotrexate treatment. In the surgical group, all 31 women treated with a curettage and all 16 treated with a laparoscopic niche resection did not require additional treatment. The subsequent ongoing pregnancy rate after cesarean scar pregnancy management was 81.1% (30/37) among women who wished to conceive, with a live birth rate of 78.4% (29/37); 1 woman was in her third trimester of pregnancy at the time of analyses. The time between cesarean scar pregnancy management and subsequent ongoing pregnancy was 4 months (interquartile range, 3-6; P=.02) after expectant management, 18 months (interquartile range, 13-22) after initial methotrexate treatment, 5 months (interquartile range, 3-14; P=.01) after a curettage, and 6 months (interquartile range, 4-15; P=.03) after a laparoscopic niche resection.

CONCLUSION

Surgical treatment of a cesarean scar pregnancy led to a high success rate without additional interventions, high pregnancy rates with a short time interval between treatment, and subsequent pregnancy leading to an ongoing pregnancy or live birth. Conservative management, both with expectant management and methotrexate treatment, led to high (re)intervention rates. Different management approaches are indicated for different types of cesarean scar pregnancies.

Curettage and sclerotherapy technique: A hybrid approach to superficial lymphatic malformation

OBJECTIVE

To describe the curettage and sclerotherapy technique, a hybrid approach to treatment for superficial lymphatic malformations.

METHODS

A retrospective analysis of a lymphatic malformation data base was performed. Patients with superficial lymphatic malformation treated by curettage and sclerotherapy technique with bleomycin were included in this study. Safety and efficacy of the curettage and sclerotherapy technique with bleomycin were evaluated.

RESULTS

Between September 2019 and October 2021, 10 consecutive patients (male/female ratio: 4:6; mean age, 10.9 years; range, 3-35 years) presented with superficial lymphatic malformations that were subsequently treated by curettage and sclerotherapy technique with bleomycin. All lesions were located on the trunk and extremities. Each patient received one treatment session and a mean follow-up of 12 months. We observed minor complications. No postoperative infections occurred in this series. No patient developed skin ulceration or necrosis. Scarring and recurrence occurred in one patient. Complete regression was confirmed for all 10 patients by photographic evaluation.

CONCLUSION

A curettage and sclerotherapy technique is proposed to treat superficial lymphatic malformation in this study. This technique seems to be safe and highly effective.

When Less Is More - Pipelle Endometrial Sampling for Quantification of Uterine Natural Killer Cells in Patients With Recurrent Implantation Failure or Habitual Abortion

Despite recent advancements in reproductive medicine, recurrent implantation failure and habitual abortion remain ongoing issues. One of the most important aspects of successful implantation is the intricate immune response and regulation necessary for the acceptance of the hemiallogenic embryo. The most numerous immune cells in the decidua are uterine natural killer cells (uNK). Studies suggest that changes in the uNK count and physiology may be responsible for the aforementioned pathological conditions. Thus, testing for uNK may provide valuable insights into their pathogenesis. The study compared Pipelle endometrial sampling with conventional curettage to find out whether the less invasive Pipelle method is a viable alternative of tissue collection. Tissue samples from 14 patients obtained by both methods were examined. The average size of tissue samples obtained with Pipelle was 17 mm2, samples obtained with curettage had on average 34 mm2. Using immunohistochemical visualization of CD56 (NK cells) and granzyme B antigens (serine protease-expressing activation state of NK cells), it was found that the average total count of CD56 / mm2 was for Pipelle 115 and 120 for curettage, respectively. The study also proved a correlation between granzyme B positivity and identification of NK cells clusters. The results indicated that Pipelle endometrial sampling seems a suitable method of tissue harvesting for the purpose of uNK cells examination. Pipelle endometrial sampling is safe, cost-effective and can be performed on an outpatient basis without the need of anesthesia or analgesia. Several issues remain yet to be solved: how to standardize the subsequent uNK testing, how to interpret the results and finally yet importantly, how to use this knowledge in personalized treatment protocols.

Grade 3 Giant Cell Tumour of the Distal Humeral Epiphysis Treated with Intralesional Curettage, High Speed Burring and Bone Grafting: A Case Report

Giant cell tumours of bone are benign but locally aggressive neoplasms involving the epi- and metaphysis of long bones. Tumours of the distal humeral epiphysis with cortical disruption and invasion into the joint and the soft tissues are rare and generally treated with wide resection and joint reconstruction. We present the case of a 19-year-old woman in whom such a tumour was successfully treated with intralesional curettage, high speed burring and autologous bone grafting. The patient underwent regular clinical and radiological follow-up. Ten years after the procedure she had no signs of tumour recurrence or degenerative changes, and she was pain free and had a normal elbow function.

Traumatic Bone Cyst of the Anterior Mandibular Region: A Case Report

A traumatic bone cyst (TBC) is an unusual non-neoplastic pseudocystic cavity in the bone that is often asymptomatic and slow-growing. It is unexpectedly detected by regular radiography imaging. These lesions are more common in the mandible than they are in the maxilla, and they are often seen in patients older than 40 years of age. A radiolucent unilocular lesion with scalloped margins is the most common radiographic appearance. If the hollow is found to contain blood or straw-colored fluid, surgical exploration is the only way to make a conclusive diagnosis of this uncommon condition. We present a case of an asymptomatic, incidentally diagnosed (on radiograph) traumatic bone cyst in a young patient involving the mandibular anterior region with periapical radiolucency. The case was diagnosed by radiographs and histopathological evaluation.

Intralesional curettage and cementation of low-grade chondrosarcomas of the appendicular skeleton: Long-term results from a single center

OBJECTIVE

The purpose of this study was to investigate the results and complications in patients who had low-grade chondrosarcomas in the appendicular skeleton and were treated by intralesional curettage and cementation within the scope of 25 years of experience in a single center.

METHODS

Ninety-one patients (72 female and 19 male) were retrospectively analyzed. The median at the time of surgery was 43 (17-78) years, and the median follow-up was 102 (26-288) months. All patients were treated by intralesional curettage followed by cementation with high-viscosity bone cement (polymethylmethacrylate). Complications and local recurrence rates, as well as clinical outcome scores were recorded.

RESULTS

Five patients (5.49%) developed local recurrence at an average of 6.6 (6-9) months postoperatively. Four were treated with local wide excision and reconstruction with tumor prosthesis. One patient received recurettage and cementation. Two recurred patients were dedifferentiated into grade II chondrosarcomas in the last intervention. No major postoperative complication was identified in the series. Patients achieved an average Musculoskeletal Tumor Society scoring system of 92.4% (standard deviation 5.2; range 80-100) in the sixth postoperative month. Musculoskeletal Tumor Society scores in the recurrent patients decreased from an average of 90% to 75.3% after the final intervention.

CONCLUSION

Intralesional curettage and cementation seem safe and reliable techniques with low recurrence and complication rates in treating low-grade chondrosarcomas of the appendicular skeleton. Clinical, radiological, and pathological evaluations are mandatory before surgical intervention, and a multidisciplinary approach is crucial. A strict follow-up regimen in the early postoperative period is needed and strongly recommended to detect local recurrence.

Experience in management of cesarean scar pregnancy and outcomes in a single center

OBJECTIVE

This study aimed to describe our experience of managing cesarean scar pregnancy (CSP) and outcomes depending on ultrasound imaging features.

METHODS

A retrospective, cohort observational study was performed on 31 consecutive patients with CSP at 6 to 9 weeks of gestation from April 2015 to January 2021. All patients were evaluated for the residual myometrial thickness (RMT), growth direction of the gestational sac (GS), blood flow, and chorionic parenchyma using ultrasonography. Patients underwent curettage or methotrexate (MTX) combined with curettage in CSP depending on the age of the GS. Blood loss of >500 mL with curettage was considered major bleeding.

RESULTS

Twenty-five (80.6%) patients had successful treatment, and six (19.4%) patients had major bleeding. The incidence of major bleeding was significantly higher in patients with >7 weeks of gestation, types II and III CSP, mixed and exogenous types of the growth direction of the GS, an RMT < 2 mm, and multiple lacunae formation in thickened chorionic parenchyma.

CONCLUSIONS

The exogenous and mixed types of the GS, an RMT < 2 mm, and multiple lacunae in thickened chorionic parenchyma may be high-risk factors for major hemorrhage by curettage in CSP.

Proximal Phalanx Enchondroma with Pathological Fracture Treated with Curettage and Bone Substitute Placement - A Case Report

Introduction

Enchondromas are predominantly seen in short tubular bones and are usually symptomless and the onset of pain may indicate a pathological fracture in most cases or malignant transformation in rare instances. Here, we report a case of proximal phalanx enchondroma with pathological fracture treated with synthetic bone substitute placement.

Case Report

A 19-year-old girl presented to the outpatient department with complaints of swelling over the right little finger. She was evaluated for the same and a roentgenogram revealed a well-defined lytic lesion in the right little finger proximal phalanx. She was planned for conservative management, but she presented 2 weeks later with an increase in pain following trivial trauma.

Conclusion

Synthetic bone substitutes are excellent materials for filling the void in benign conditions as they form resorbable scaffolds which have good osteoconductive properties and are associated with no donor site morbidity.

Giant Cell Tumor of Talus - A Case Report

Introduction

A giant cell tumor (GCT) is a benign tumor of bones which commonly arises from epiphysis of long bones. The tumor is locally aggressive and rarely metastasizes to the lungs. GCT of small bones of the foot and ankle is very rare. The GCT of the talus is very rare, and only a few case reports and series are described in the literature. In general, the GCT is monostotic, and few incidences of multicentricity have been described in the foot and ankle bones literature. Here are the findings of our case GCT of talus and reviews of earlier literature.

Case Report

We present a case of a GCT of the talus in a 22-year-old female. Patient presented with pain in ankle with mild swelling and tenderness at ankle. Radiograph and Computer tomography scan conformed an eccentric osteolytic lesion on anterolateral part of talus body. Magnetic resonance imaging showed no extra osseous extension or articular surface breach. Biopsy conformed the lesion to be giant cell tumor. The tumor was reated with curettage and bone cement filling.

Conclusion

Giant cell tumor of talus is extremely rare and presentation of these tumor may change. Curettage and bone cementing are an effective method of treatment. It gives early weight bearing and rehabilitation.
