Mediastinal Parathyroid Adenoma Causing Primary Hyperparathyroidism, Farhat Abbas, Syed Raziuddin Biyabani, Amanullah Memon, Jamsheer Jehangir Talati Feb 2007

Mediastinal Parathyroid Adenoma Causing Primary Hyperparathyroidism, Farhat Abbas, Syed Raziuddin Biyabani, Amanullah Memon, Jamsheer Jehangir Talati

Section of Urology

An ectopically placed parathyroid adenoma in the anterior mediastinum is a rare cause of persistent or recurrent primary hyperparathyroidism (PHPT) and is recognized as an important cause of failed primary neck exploration. We encountered 3 such cases amongst 70 surgically treated patients with PHPT (4.3%) over a 20-year period. In 2 cases, the offending adenoma could be removed at first exploration whereas in the 3rd case, it was successfully removed with mediastinal exploration after 2 failed neck explorations. In established cases of PHPT with equivocal preoperative localization studies or negative neck explorations, an ectopically placed parathyroid adenoma should be considered …

Extent Of Lymphadenectomy In Radical Cystectomy For Bladder Cancer, Muhammad Hammad Ather, Sadaf Fatima, Orhun Sinanoglu Jul 2005

Extent Of Lymphadenectomy In Radical Cystectomy For Bladder Cancer, Muhammad Hammad Ather, Sadaf Fatima, Orhun Sinanoglu

Section of Urology

Background: The benefit of pelvic lymphadenectomy in patients with cancer of the urinary bladder remains controversial. Though the inclusion of lymph node dissection in conjunction with radical cystectomy for patients with clinically negative nodes is well accepted, however, the extent of the nodal dissection remains contentious, particularly in patients with gross disease and T1G3 cancer. The extent of the primary bladder tumor, number of lymph nodes removed and the lymph node tumor burden are important prognostic variables in patients undergoing cystectomy. We analyzed the impact of the extent of lymphadenectomy during radical cystectomy on survival in the contemporary literature.
Methods: …

Expression Of Ps2 In Prostate Cancer Correlates With Grade And Chromogranin A Expression But Not With Stage, Hammad Ather, Farhat Abbas, Nuzhat Faruqui, M Israr, Shahid Pervez

Department of Pathology and Laboratory Medicine

Background: The biological potential of prostate cancer is extremely variable. Particular interest is focused on markers not expressed in normal prostatic tissues. pS2 protein expression has been demonstrated in a range of malignant tissues in an oestrogen-independent pathway. Recently, it has been demonstrated that pS2, in prostate cancer, is closely associated with neuro-endocrine differentiation. In the present study, we have analyzed, the potential of Neuro-endocrine and pS2 (TFF1) expression in human prostate cancer determined by immunohistochemistry, in primary adenocarcinoma of the prostate and attempted to correlate this with the clinico-pathologic features of the patient and neuroendocrine expression.

Methods: Ninety-five malignant …

Post-Chemotherapy Residual Mass In Stage Iic Seminomatous Testicular Tumor, N A. Ahmad, S R. Biyabani, Farhat Abbas

Section of Urology

Introduction

The management of patients with residual masses following chemotherapy for advanced seminoma remains a difficult problem with no clear guidelines. While most patients with advanced seminoma achieve a complete or partial response with cisplatin based chemotherapy1, a significant number will reveal a residual mass on follow up CT scan or MR imaging2,3. Management options for post chemotherapy residual mass in a case of seminoma include close observation, radiation therapy and excisional surgery. While 80 to 85% of residual masses represent either fibrosis or necrotic tissue needing no further therapy, 10 to 15% may contain viable …

Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel Jun 1997

Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel

Department of Pathology and Laboratory Medicine

Prostate cancer is an enigmatic disease. Although prostatic-intraepithelial neoplasia appears as early as the third decade and as many as 80% of 80 year old men have epithelial cells in their prostate that fit the morphological criteria for cancer, only about 10% of men will ever have the clinical disease and less than 3% will die from it. There have been no significant proven interventions which have altered the natural history of the disease since hormone down regulation was introduced in the 1940s and new research has been poorly supported. There is however an urgent need to develop new criteria …

Role Of Thymectomy In Myasthenia Gravis, Sohaila Mohsin Ali, Aziz Sonawalla, Irfan Altafullah, Hizbullah Sheikh

Section of Urology

Thirteen patients with myasthenia gravis underwent total thymectomy between January, 1988 and December, 1991. The duration of symptoms prior to surgery varied from 2 months to 20 years. In a follow-up ranging from 2 months to 4 years, 11 patients showed a significant improvement with either complete discontinuation of medication of a marked reduction in doses. One patient with a small benign thymoma showed some improvement but subsequently required stepping up of anticholinesterase medication and addition of steroids and immune suppressants; another patient with atrophic thymic tissue had complete remission after thymectomy but developed myasthenic symptoms six months later requiring …


Sertoli Cell Only Syndrome (Secos): Lessons From Case Studies, Jamsheer J Talati, Hizbullah Sheikh Sep 1991

Sertoli Cell Only Syndrome (Secos): Lessons From Case Studies, Jamsheer J Talati, Hizbullah Sheikh

Section of Urology

Between June 85 and December 87, 69 testicular biopsies were submitted for histopathological examination during investigation of infertility; ten (14%) patients had a Sertoli cell only syndrome. The history, clinical features, and hormonal profiles were analyzed in an attempt to categorize these patients on aetiological basis. Two followed treatment of malignancy--one by radiation for testicular cancer and one by cyclophosphamide for a lymphoma. One had unilateral cryptorchidism. Mumps was etiological factor in one patient. FSH levels determined in 6 patients were elevated in all suggesting a possible dependence of (sick) Sertoli cells on spermatogenic cells for production of inhibin. Alternative …


Extracorporeal Shock Wave Lithotripsy, Jamsheer J Talati Jan 1990

Extracorporeal Shock Wave Lithotripsy, Jamsheer J Talati

Section of Urology

After circumcision the first operations done on man were for bladder stone. Done by charlatans the operation often resulted in loss of life and caused the early lithotomists to maintain a peri­patetic existence, vanishing from the town the night after surgery was performed. About two centuries ago stones became a common disease amongst kings: surgeons took over from the charlatans and commenced blind skilful mechanical lithotripsy where a curved instrument was introduced per urethram, its jaws opened to engage the stone which was then crushed by a mechanical (screw driven) closure of the jaws. Now-a-days urinary bladder lithotripsy is done …
