Malignant, fungating giant-cell tumor of the tendon sheath (GCT-TS) of the foot: A case report

Giant-cell tumors of the tendon sheath (GCT-TS) are relatively common benign tumors that arise in close proximity to joints and tendons. Malignant GCT-TS are extremely rare. Surgery with wide resection remains the cornerstone for treating malignant giant-cell tumors of the tendon sheath especially in large tumor cases.

Osteosarcoma of the distal fibula and reconstruction of the ankle using inverted fibula, a case report

INTRODUCTION AND IMPORTANCE

Osteosarcomas are malignant primary bone tumors of mesenchymal origin producing osteoid material and has peak incidence in adolescents. Distal lower limb tumors are rare and can negatively affect ankle joint stability.

CASE PRESENTATION

A 24-year-old female who has newly graduated from college presented with distal fibular mass measuring around 5 × 15 cm located on the lateral aspect of the right ankle over a period of 2 months. The mass located on the lateral aspect of the right ankle that was hard, oval and measuring around 5 × 15 cm and originating from the fibula. The overlying skin was normal with no discharging sinuses. Distal neurovascular examination was normal with no lymphadenopathy. Imaging using X-rays and MRI as well as pathological examinations thereafter has proven the diagnosis. She was planned for wide surgical resection at distal fibula and ankle reconstruction after neoadjuvant chemotherapy, then for adjuvant chemotherapy. Ankle reconstruction using fibular autograft was used after its reversal and was then stabilization by syndesmotic screws. She has clinically good outcome.

CLINICAL DISCUSSION

Surgery with extensive and meticulous dissection remains the cornerstone for treating osteosarcomas affecting distal fibula. Neoadjuvant and adjuvant chemotherapy are important for managing micro-metastasis. Ankle reconstruction and be performed using different methods with good outcomes.

CONCLUSION

Lesson learnt is that ankle reconstruction using fibular autograft can be used after reversal and stabilization by screws with good outcome for managing distal fibular osteosarcomas. However, this finding needs to be strengthened with future reports.

Misdiagnosis of Ewing’s sarcoma, A tragedy of a young female initially diagnosed with chronic osteomyelitis and ended with disarticulation (Case report).. [DOI: 10.22541/au.165331806.69833732/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

We report a case of a 9-year-old girl with Ewing’s who was initially thought to have osteomyelitis. As part of osteomyelitis management, an attempt of drilling the cortex has paved the way for the tumor to extend to all thigh compartments which was beyond salvage. Disarticulation was the final result.

Clinical Characteristics and Risk Factors Associated with Severe Disease Progression among COVID-19 Patients In Wad Medani Isolation Centers: A Multicenter Retrospective Cross-Sectional Study

Background

Since December 2019, (COVID-19) has had a significant impact on global health systems. Because little is known about the clinical characteristics and risk factors connected with COVID-19 severity in Sudanese patients, it is vital to summarize the clinical characteristics of COVID-19 patients and to investigate the risk factors linked to COVID-19 severity.

Objectives

We aimed to assess the clinical characteristics of COVID-19 patients and look into risk factors associated with COVID-19 severity.

Methods

This is a retrospective cross-sectional study that took place in two Isolation Centers in Wad Medani, Gezira State, Sudan. Four hundred and eighteen patients were included between May 2020 and May 2021. All COVID-19 patients over the age of 18 who were proven COVID-19 positive by nucleic acid testing or had characteristics suggestive of COVID-19 on a chest CT scan and had a complete medical record in the study period were included.

Results

The participants in this study were 418 confirmed COVID-19 cases with a median age of 66.313 years. There were 279 men (66.7%) among the patients. The most prevalent comorbidities were hypertension (n = 195; 46.7%) and diabetes (n = 187; 44.7%). Fever (n = 303; 72.5%), cough (n = 278; 66.5%), and dyspnea (n = 256; 61.2%) were the most prevalent symptoms at the onset of COVID-19. The overall mortality rate (n = 148) was 35.4%. Patients with severe illness had a mortality rate of 42.3% (n = 118). Older age, anemia, neutrophilia, and lymphocytopenia, as well as higher glucose, HbA1c, and creatinine levels, were all linked to severe COVID-19, according to the chi-square test and analysis of variance analysis.

Conclusion

Sixteen variables were found to be associated with COVID-19 severity. These patients are more prone to go through a serious infection and as a result have a greater death rate than those who do not have these characteristics.

Health system and patient-level factors serving as facilitators and barriers to rheumatic heart disease care in Sudan

BACKGROUND

Rheumatic heart disease (RHD) remains a leading cause of morbidity and mortality in Sub-Saharan Africa despite widely available preventive therapies such as prophylactic benzathine penicillin G (BPG). In this study, we sought to characterize facilitators and barriers to optimal RHD treatment with BPG in Sudan.

METHODS

We conducted a mixed-methods study, collecting survey data from 397 patients who were enrolled in a national RHD registry between July and November 2017. The cross-sectional surveys included information on demographics, healthcare access, and patient perspectives on treatment barriers and facilitators. Factors associated with increased likelihood of RHD treatment adherence to prophylactic BPG were assessed by using adjusted logistic regression. These data were enhanced by focus group discussions with 20 participants, to further explore health system factors impacting RHD care.

RESULTS

Our quantitative analysis revealed that only 32% of the study cohort reported optimal prophylaxis adherence. Younger age, reduced primary RHD healthcare facility wait time, perception of adequate health facility staffing, increased treatment costs, and high patient knowledge about RHD were significantly associated with increased odds of treatment adherence. Qualitative data revealed significant barriers to RHD treatment arising from health services factors at the health system level, including lack of access due to inadequate healthcare staffing, lack of faith in local healthcare systems, poor ancillary services, and patient lack of understanding of disease. Facilitators of RHD treatment included strong interpersonal support.

CONCLUSIONS

Multiple patient and system-level barriers to RHD prophylaxis adherence were identified in Khartoum, Sudan. These included patient self-efficacy and participant perception of healthcare facility quality. Strengthening local health system infrastructure, while enhancing RHD patient education, may help to improve treatment adherence in this vulnerable population.

Abdominal cocoon syndrome, a case report of a rare disease entity causing intestinal obstruction

INTRODUCTION AND IMPORTANCE

Abdominal cocoon syndrome is a rare condition characterized by small bowel encapsulation by a fibrous membrane or a cocoon-like sac. It is an uncommon cause of intestinal obstruction. Less than 300 cases have been reported from all over the world. This is the first case of such a disease entity to be reported from Sudan.

CASE PRESENTATION

A young female patient, presented with features of intestinal obstruction that was managed conservatively. Failure of the conservative management has warranted a laparotomy.

CLINICAL FINDINGS AND INVESTIGATIONS

Her features were suggestive of intestinal obstruction that was confirmed radiologically.

INTERVENTIONS AND OUTCOME

Laparotomy revealed a membrane-like fibrous material and extensive multiple loops adhesions, findings consistent with primary sclerosing encapsulating peritonitis (PSEP), also known as abdominal cocoon's disease. The membrane was excised and adhesiolysis was done. Intestinal obstruction was relieved after surgery and the patient showed good outcome.

CONCLUSIONS

Abdominal cocoon syndrome is a rare cause of intestinal obstruction.

RELEVANCE AND IMPACT

The takeaway lesson from this case would be that the PSEP should be sought in any patient with no clear cause for obstruction can be identified. A contrast-enhanced CT scan is the diagnostic modality of choice. Finally, we think that the disease is underreported from Africa and more efforts should be carried out to increase patients' access to healthcare especially in rural areas with no access to hospitals in order to bring more cases to light. This case report has been reported in line with the SCARE Criteria (Agha et al., 2020 [17]).

Endoscopic ultrasound-guided drainage of abdominal fluid collections after pancreatic surgery: Efficacy and long-term follow-up

BACKGROUND/PURPOSE

Endoscopic ultrasound-guided drainage (EUS-GD) of postoperative abdominal fluid collections (POFC) following pancreatic surgery is used as an alternative or complement to percutaneous drainage (PD) procedure. The present single-center retrospective study evaluates its efficacy and safety.

METHOD

We included consecutive cases with POFC treated by EUS-GD between September 2009 and November 2014 in our department. Technical success, long-term clinical success, recurrence rate and need for surgery were analyzed.

RESULTS

24 procedures in 20 patients (95 % after pancreatic resection) were assessed. Indications for surgery included tumors/lesions located in the pancreas (15/20), chronic pancreatitis (3/20) and duodenal adenoma not completely resectable endoscopically (2/20). EUS-GD was performed within a median of 30 days (IQR: 8.25) for a median fluid collection size of 72.5 mm (IQR: 46.25), requiring a mean of 1.2 sessions with placement of a mean of 2.1 plastic stents (7 Fr/10 Fr) per patient for a mean of 89 days (IQR: 127). Microbiology of aspirated fluid revealed positive cultures in 13 patients, mostly polymicrobial, isolated positive for fungal and 3 multidrug-resistant gram negative (MRGN) in 4 cases. An additional transpapillary drainage was inserted in 1/20 patients. 4/20 patients received PD, mostly before EUS-GD. Technical and clinical success was achieved in 20/20 (100 %) and 18/20 (90 %) patients, respectively, while 2 patients required re-operation. During follow-up (median 630 days after stent removal, range: 45 - 2160), recurrence occurred in 1/18 (5.5 %) patient that was referred for surgery. No death or severe adverse events were noted.

CONCLUSION

EUS-GD is an effective, minimally invasive and safe method for therapy of POFC after pancreatic surgery offering long-term remission in about 95 % of cases.

Chlorination byproducts in drinking water produced from thermal desalination in United Arab Emirates

Oil activities in the Arabian Gulf can potentially affect the quality of the intake water available for coastal desalination plants. This paper addresses such situation by investigating the quality of intake water and desalinated water produced by a desalination plant located near a coastal industrial complex in United Arab Emirates (UAE). Analyses of the organic compounds on the intake seawater reported non-detected levels in most samples for the three tested organic groups; namely Polyaromatic Hydrocarbons (PAHs), Phenols, and Polychlorinated Biphenyls (PCBs). Trihalomethanes (THMs) and Haloacetic Acids (HAAs) were also tracked in the intake sea water, throughout the desalination processes, and in the final produced drinking water, to evaluate the undertaken pre- and post chlorination practices. The levels of considered Chlorination Byproducts (CBPs) were mostly found below the permissible international limits with few exceptions showing tangible levels of bromoform in the intake seawater and in the final produced drinking water as well. Lab-controlled experiments on the final produced distillate showed little contribution of its blending with small percentage of seawater upon the formation of trihalomethane and in particular, bromoform. Such results indicate that the organic precursors originated in the seawater are responsible for bromoform formation in the final distillate.
