Leiomyosarcoma Presenting As A Spontaneously Ruptured Renal Tumor-Case Report, Mohammad Moazzam, M Hammad Ather, Akber S. Hussainy
Leiomyosarcoma Presenting As A Spontaneously Ruptured Renal Tumor-Case Report, Mohammad Moazzam, M Hammad Ather, Akber S. Hussainy
Department of Pathology and Laboratory Medicine
Background:
Ruptured renal neoplasms can be a catastrophic clinical presentation. Angiomyolipoma is the commonest renal tumor which presents in this fashion. Renal sarcomas are rare renal neoplasms. Renal leiomyosarcomas are the most common histological subtype of renal sarcomas, accounting for approximately 50-60% of the reported cases. These tumors are usually peripherally located and appear to arise from either the renal capsule or smooth muscle tissue in the renal pelvic wall.
Case presentation:
A 70 years old male, with hypertension and ischemic disease, developed acute left flank pain. The general physician evaluated this using ultrasound, which showed a solid left renal …

Csf Oligoclonal Bands In Multiple Sclerosis, I Siddiqui, S Aleem, N Kayani, S Baig
Department of Pathology and Laboratory Medicine
Objective:
To study the significance of oligoclonal bands in neurological disorders, specifically in Multiple Sclerosis (MS).
Methods:
The study was designed to assess the sensitivity and specificity of the test methodology of CSF electrophoresis by performing the retrospective analysis of CSF samples sent for oligoclonal bands (OCB). A total of 603 samples were received by the Clinical Laboratories, Department of Pathology of The Aga Khan University, during a period of 54 months (January 1993-June 1997). All of these samples were analyzed by performing CSF protein electrophoresis. One hundred thirty three out of 603 samples showed evidence of OCB. Out …
Characterization Of Pathogenic Mutations In 21-Hydroxylase Gene Of Pakistani Patients With Congenital Adrenal Hyperplasia And Their Family Members--A Preliminary Report, A H. Khan, M I. Nasir, T Moatter
Characterization Of Pathogenic Mutations In 21-Hydroxylase Gene Of Pakistani Patients With Congenital Adrenal Hyperplasia And Their Family Members--A Preliminary Report, A H. Khan, M I. Nasir, T Moatter
Department of Pathology and Laboratory Medicine
Objective:
To characterize specific mutations within the 21-hydroxylase gene (CYP21-B) using ARMS-PCR assay in patients with congenital adrenal hyperplasia (CAH) and to compare it with that reported in other populations.
Subjects and Methods:
Five families, having an index case with CAH diagnosed on the basis of clinical and biochemical findings volunteered to give blood samples for analysis. A strategy, based on ARMS-PCR (Amplified Refractory Mutation System) was employed for the detection of mutations in 21-hydroxylase gene. The products of ARMS-PCR were resolved on agarose gels and the PCR products were visualized over ultra violet illumination.
Results:
Twenty-six specimens were analyzed …

In this study the anti-proliferative effect of curcumin (curcuma longa) that is the active ingredient of ground dried rhizome has been studied against three local and three reference leishmanial strains, Leishmania major, Leishmania tropica and Leishmania infantum (Pakistani isolate). Curcumin has shown an average IC50 of 5.3mM against promastigotes of various leishmanial strains which is much lower as compared with pentamidine that is one of the basic treatments against leishmaniasis. The main draw back attributed to these assays performed on promastigotes is the heterogeneity of results compared with those obtained with intracellular amastigotes or with in vivo effect. We also …
