Aggressive angiomyxoma of renal pelvis in a horseshoe-shaped kidney: Rare tumor at an unusual site

Mesenchymal neoplasm is rare in renal pelvic region. Aggressive angiomyxomas are the neoplasms seen predominantly in female genital region. These tumors are locally aggressive with rare cases presenting with metastasis. Its occurrence in renal pelvis is extremely rare with only five cases reported in the literature. The present case is the sixth case reported in a 15-year-old girl who presented to the surgery department as a case of horseshoe kidney. The mass was excised and a diagnosis of aggressive angiomyxoma was rendered.

Utility of FNAC in Dermatological Manifestations of Metastatic Cancer with the Review of the Literature

Objectives

Cutaneous metastasis (CM) though rare, indicates a terminal event in any malignancy and has a grave outcome. The present study reiterates the role of fine needle aspiration cytology (FNAC) in the diagnosis of metastatic cutaneous nodules.

Materials and Methods

From 2015 to 2017, the department received 22,000 cases for FNAC. Among these cases, aspirations from the skin and subcutaneous region were performed on 6,083 cases. After excluding primary tumors of skin/subcutis, 25 cases on cytology were suggestive of metastasis. Clinicoradiological and histopathological profiles in these cases were reviewed.

Results

Among these 25 patients, the male to female ratio was 1:1.09 (F, 12; M, 13) in the age group of 18-72 years. Most common primary malignancy in females was of breast and in males was gall bladder. The most common manifestation was a palpable skin nodule, with the abdominal wall being the predominant site. The most common diagnosis, on cytology, was metastatic adenocarcinoma.

Conclusion

FNAC is a minimally invasive method, which aides in prompt detection and appropriate management of cases presenting with skin nodules and clinically unsuspected of malignancy. Whereas in known primary tumor, it indicates dismal prognosis by diagnosing CM; in cases with unknown primaries, cytomorphology in conjunction with clinicoradiological findings often gives a clue to the possible primary site.

Haemophilic pseudotumour: surgical management of a rare case

Haemophilia is a common cause of genetically inherited bleeding disorders. Pseudotumours occur in 1-2 % of persons with severe forms of haemophilia. These are a result of repeated haemorrhage into soft tissues, subperiosteum or a site of bone fracture with inadequate resorption of the extravasated blood. There are a number of therapeutic alternatives for this dangerous condition: surgical removal, percutaneous management, irradiation, embolization etc. In this case report, we describe the natural history, clinical course and successful surgical management of a patient with haemophilia who presented with a massive pseudotumour. We also briefly review the relevant literature on the various therapeutic modalities that have been implemented in the management of this rare complication. Though surgeons may be averse to operate on haemophiliacs, primary surgical management as done in our case may prove to be the definitive treatment option for such patients.

Squamous cell carcinoma of the scrotum - still an occupational hazard

Squamous cell carcinoma (SCC) of the scrotum was one of the first occupational diseases to be described, and acquired its eponym from Sir Percivall Pott. The condition has now become rare owing to the establishment of industrial health norms. A 45-year-old male with a history of long-term exposure to petrochemicals presented to our institution with a scrotal lesion and underwent wide-local excision of the same. Histopathology revealed well-differentiated SCC involving the epididymis. Treatment options included excision with ilio-inguinal bloc dissection (in the event of lymphadenopathy) with subsequent chemotherapy and/or radiotherapy. Tumors following occupational exposure thus continue to contribute to the rapidly decreasing incidence of scrotal carcinoma.

Video-assisted thoracoscopic decompression of tubercular spondylitis: clinical evaluation

STUDY DESIGN

A prospective, observational study using a novel procedure of video-assisted thoracoscopy and conventional, long spinal instruments for decompression of dorsal tubercular spondylitis.

OBJECTIVES

To assess the efficacy of video-assisted thoracoscopic decompression of dorsal tubercular spondylitis and compare it with the published data of classic thoracotomy procedures.

SUMMARY OF BACKGROUND DATA

Surgical decompression of dorsal tubercular spine with the transpleural transthoracic method is a standard procedure. It is a major surgery with significant morbidity in terms of blood loss, intensive care unit (ICU) and hospital stay, postoperative incision pain, and chest tube insertion. A procedure that has the potential to achieve comparable recovery in patients with dorsal tubercular spondylitis but with a surgery of lesser magnitude and morbidity has immense potential.

METHODS

There were 16 patients with mid-dorsal tubercular spondylitis with paraplegia/paraparesis requiring surgery who were included in the study. Every patient had a recent paradiscal disease at a single level. A soft tissue shadow was visible on plain radiographs of the spine, and conservative treatment for at least 3 weeks had shown no recovery. Patients with obvious respiratory insufficiency and likely to have significant pleural adhesions were excluded from the study. Single lung anesthesia and ipsilateral lung collapse using a double-lumen tube were administered. A 3-portal thoracoscopy approach was used, and conventional but long spinal instruments were used through an open port to decompress the spine. Patients were assessed for blood loss, duration of surgery, postoperative incision pain, duration of chest tube insertion, ICU and hospital stay, and neurologic recovery. Patients were observed for a minimum of 6 months.

RESULTS

Of 16 patients, 14 (88%) had good neurologic recovery. In 1 patient, thoracoscopy was abandoned, and open thoracotomy was performed because of persistent bleeding. Another patient did not recover, and anterolateral decompression was performed 10 weeks after thoracoscopy. She recovered subsequently. Other complications included fracture of the sixth rib in 1 patient and breakage of suction tip in another. Adequate tissue biopsy for histopathologic examination could be obtained in all patients. Duration of surgery was 223 minutes (+/-56), blood loss was 497 ml (+/-302), and blood transfusion was required in 3 patients (3 U in 1 and 1 U in 2). Postoperative analgesic (tramadol) was 243 mg (+/-70) for 2-4 days (median 3), median hospital stay was 5.5 days (range 4-9), chest tube requirement was 3 days (range 2-7), and 2 patients were required to stay in the ICU for 1 day each.

CONCLUSION

Video-assisted thoracoscopic decompression of tubercular dorsal spondylitis is a viable option to achieve significant neurologic recovery with less morbidity, blood requirement, and hospital stay compared to the open thoracotomy procedures.

Randomized controlled trial to compare the early and mid-term results of stapled versus open hemorrhoidectomy

BACKGROUND

The new technique of circular stapler for the treatment of hemorrhoids has shown early promise in terms of minimal or no postoperative pain, early discharge from hospital, and quick return to work. This study was designed to compare stapled technique with the well-accepted conventional Milligan Morgan hemorrhoidectomy.

METHODS

After fulfilling the selection criteria, 84 patients were randomly allocated to the stapled (n = 42) or open group (n = 42). All patients were operated on under spinal anesthesia. The 2 techniques were evaluated with respect to the operative time, pain scores, complications, day of discharge, return to work, and level of satisfaction.

RESULTS

The mean age of patients was 46.02 years (SD, 12.33) in the stapled group and 48.64 years (14.57) in the open group. Grade III or IV hemorrhoids were more common in men (ie, 80.9% and 85.7% in the stapled and open group, respectively). The mean operative time was shorter in the stapled group 24.28 minutes (4.25) versus 45.21 minutes (5.36) in the Milligan-Morgan group (P < .001). The blood loss, pain scores and requirement of analgesics was significantly less in the stapled group. Mean hospital stay was 1.24 days (0.62) and 2.76 days (1.01) (P < .001) in the stapled and open group, respectively. The patients in the stapled group returned to work or routine activities earlier (ie, within 8.12 days [2.48]) as compared with 17.62 (5.59) in the open group. Only 88.1% of patients were satisfied by the open method compared with 97.6% after the stapled technique. The median follow-up period was 11 months with a maximum follow-up of 19 months (range 2-19 months).

CONCLUSIONS

Stapled hemorrhoidectomy is a safe and effective day-care procedure for the treatment of grade III and grade IV hemorrhoids. It ensures lesser postoperative pain, early discharge, less time off work, complications similar to the open technique, and in the end a more satisfied patient with no perianal wound. However, more such randomized trials are essential to deny any long-term complication.

Open port placement of the first laparoscopic port: a safe technique

BACKGROUND

Blind insertion of the Veress needle and of the first trocar is a significant cause of complications in laparoscopic surgery. Despite this risk, the closed technique is still more popular than the open one. Our aim is to report the results of our experience with the routine use of the modified open technique in laparoscopic surgery and to describe the technical details of the creation of pnuemoperitoneum by the open technique that we used.

METHODS

A prospective study was conducted in the department of surgery at Maulana Azad Medical College and associated Lok Nayak Hospital, New Delhi. A modified method of open laparoscopy was performed on 755 consecutive patients requiring laparoscopy or laparoscopic surgery over a 5-year period from August 1998 to February 2003 in 1 surgical unit.

RESULTS

The mean time taken was 4 minutes (range, 2 to 10). No intraoperative complications occurred during trocar insertion. Forty-nine (6.49%) patients had minor umbilical sepsis, 22 (2.91%) had periumbilical hematoma, but none had umbilical hernia during 3 months of follow-up after surgery.

CONCLUSION

Based on our own experience, we recommend open laparoscopy as a safe and easy approach for routine laparoscopic interventions.

A difficult laparoscopic cholecystectomy that requires conversion to open procedure can be predicted by preoperative ultrasonography

A prospective study was conducted from March 1999 to April 2000 that included 73 patients who underwent elective laparoscopic cholecystectomy for uncomplicated gallstone disease. The study was conducted at one surgical unit in the Department of Surgery and Department of Radio-diagnosis and one surgical unit in the Department of Surgery, Maulana Azad Medical College and the associated Lok Nayak Hospital, which is the largest referral hospital in northern India and is located in the capital of India. A preoperative ultrasound was performed just prior to surgery, and 4 ultrasonographic parameters were analyzed. namely gallbladder wall thickness, contracted gallbladder, impaction of gallstones at the neck of the gallbladder, and common bile duct stones. The surgical findings were objectively graded as difficult or easy laparoscopic cholecystectomy according to 5 operative parameters, namely total time taken for the surgery, time taken to dissect gallbladder bed, spillage of stones, tear of gallbladder during dissection, and conversion to the open procedure. Of the 73 cases, 17 (23.3%) were conversions to the open procedure. Of the 21 (28.76%) cases predicted to be difficult, 17 (23.3%) were technically difficult, of which 13 (17.8%) were converted to the open procedure. Of the 52 (71.23%) cases predicted to be easy on ultrasonography, only 7 (9.38%) were found to be difficult on surgery, of which only 4 (5.48%) had to be converted to the open procedure. Based on our results, we conclude that preoperative ultrasonography is of great value in selecting patients preoperatively for laparoscopic cholecystectomy and minimizing complications and conversion to the open procedure.

Experiences with ESR (endolymphatic sac revascularization) in cases of sensorineural hearing-loss

Experience based on 14 cases of severe-to-total sensorineural deafness, treated with endolymphatic sac revascularization, operation, is presented. Changes seen in the endolymphatic sacs and lateral sinuses of these patients have been detailed. Irrespective of the degree and duration of deafness, significant hearing gain (with good improvement in speech discrimination) was obtained in nine out of 14 cases (64.28 per cent). There was no improvement at all in one out of 14 (7.14 per cent), and there was a relapse of the hearing-loss two months post-operatively in one case (7.14 per cent). Tinnitus disappeared in the operated ear in three out of five cases (60 per cent) and vertigo improved considerably in four out of six cases (66.66 per cent). The follow-up in this series has been up to two years.

Absorption spectra of bone

Absorption spectra of human bone and its two major constituents (collagen and apatite) were obtained in the wavelength region extending from 2000 to 12,000 A. In the last two cases a minimum transmission (maximum absorption) was uniformly observed in the ultraviolet region. The two samples after exposure to ultraviolet radiations show a shift in the peak positions. Absorption peaks in the total bone spectra are not reproducible in its two constituents. After exposure to UV radiations the position of maximum absorption is displaced. A possible interpretation of the observed results is presented.

Bilateral Vidian neurectomy--indications and results

Indications and results of 125 Vidian neurectomies done in 64 patients have been presented. The indications were grouped as: Rhinorrhoea (37.5%), Nasal Polyposis (3.12%); Headaches and Faceaches (45.32%); and Bronchial Asthma (14-06%). Four initial Vidian neurectomies were done unilaterally and produced only partial relief in symptoms. Bilateral Vidian neurectomy relieved completely all the rhinorrhoea cases, all the nasal polyposis cases, 79-3% of headache and faceache cases and 55-5% of bronchial asthma cases.

The effect of ultraviolet radiation on the electrical conductivity of human bone

The electrical conductivity of intact bone, collagen and apatite mineral was determined in the region of moderately high fields. After exposure to ultraviolet (UV) radiation the conductivity of the specimens was redetermined. Following exposure marked decreases in electrical conductivity occurred in all specimens. The possible modes of interaction of UV radiation with bone are discussed. It is suggested that protonic conduction may be an important mode of charge transport in bone.
