Peculiar Histopathological Features Of Giardiasis In Distal Duodenal Biopsies, Z Abbas, A A. Qureshi, H Sheikh, S M. Jafri, A H. Khan Sep 1994

Peculiar Histopathological Features Of Giardiasis In Distal Duodenal Biopsies, Z Abbas, A A. Qureshi, H Sheikh, S M. Jafri, A H. Khan

Department of Pathology and Laboratory Medicine

Histological changes in 20 Giardia positive duodenal biopsies (Group A) were compared with 50, Giardia negative duodenal biopsies (Group B), taken during the same period. Stool examinations in Group B were negative for Giardia. Surface epithelium, villous and crypt architecture and cellular infiltrates were examined and compared between the groups. Atrophic changes in the villi were more common in Group A as compared to B(P < 0.0001). Intraepithelial neutrophil infiltration (P < 0.001), infiltration of the lamina propria with plasma cells (P < 0.5), and presence of eosinophils in the lamina propria (P < 0.001) were significant findings in group A. Some of the changes were related to the density of Giardia colonization e.g., the goblet cell depletion (P < 0.05) and the density of plasma cell infiltration in lamina propria (P < 0.01). Erosions and ulcerations were less commonly seen in group A. Thus we conclude that giardiasis manifests its peculiar features in the distal duodenal mucosa and a biopsy of this region is an important diagnostic tool for detection of this disease.

Immunohistochemical Estrogen Receptor Determination In Human Breast Carcinoma: Correlation With Histologic Differentiation And Age Of The Patients, Shahid Pervez, S. Shaikh, F. Aijaz, S. A. Aziz, M. Naqvi, Sheema H. Hasan

Department of Pathology and Laboratory Medicine

An immunohistochemical assay for the measurement of estrogen receptor (ER) has been evaluated on 290 consecutive human breast biopsy and mastectomy specimens in the year 1992 at The Aga Khan University Hospital laboratories. Immunohistochemical localization of estrogen receptor on frozen/paraffin section was scored in a semi-quantitative fashion incorporating both the intensity and the distribution of specific staining. Histologic grading of the tumour was performed according to Bloom’s method. In this study, 21% of the tumours were estrogen receptor negative, 15% were weak positive, 25% intermediate positive and 39% strong positive. Fifty percent of the well differentiated tumours showed strong ER …


Amoebic Appendicitis--A Rare Entity, Raheem Ahmed, Hizbullah Shaikh, Muhammad Siddiqui, M Ahmed Apr 1994

Amoebic Appendicitis--A Rare Entity, Raheem Ahmed, Hizbullah Shaikh, Muhammad Siddiqui, M Ahmed

Department of Pathology and Laboratory Medicine

Appendectomy is the most common surgical procedure performed in routine general surgical practice. However, not all the appendices removed, are submitted for histopathological examination in this part of the world. We reviewed 1400 appendices received by our department from within our hospital and from outside the hospital. Of these 13 cases were reported as amoebic appendicitis. These patients did not have any different clinical presentation from the patients who were reported as acute appendicitis without amoebae. Microscopically these appendices had minimal neutrophil polymorph infiltration accompanied by tissue necrosis and amoebic trophozoites within the appendiceal wall. After histological diagnosis, different tests …

A View Of Hiv--Infection In Karachi, Naila Kayani, Aamir Sheikh, Asif Khan, Chhotoobhai Mithani, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

A prospective study on the prevalence of HIV-l infection in Karachi, Pakistan was conducted over a period of six years (1986-1992). Over 15,000 individualsamples and more than 32,000 donor units of individuals residing in Karachi at the time of sample co llection were tested for HIV-I infection by our screening test EIA which revealed a positivity rate of 0.23% and 0.003% in individual and donor units respectively by Western Blot. We divided patients into four groups A,B,C and D based on the most plausible cause of transmission. The largest number of positive patients belonged to group B, who were of …

Pattern Of Dyslipoproteinemia In Selected Population Of Karachi, Erum Khan, Ayesha Molla, Naila Kayani, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

Pattern of dyslipoproteinemia was studied ,over a period of 3-1/2 years in 487(394 males, 93 females) cases aged 4 to above 70 years. Type IV hyperlipoproteinemia was most prevalent (36%) followed by type V (15%)
