Department of Pathology and Laboratory Medicine

Abstract

Objective: To see the morphological pattern of benign and malignant ovarian neoplasms. Method: Retrospective study of all consecutive cases of ovarian neoplasms diagnosed at Aga Khan University Hospital between 1st January 1993 and 30th September 1998. Setting: The Section of Histopathology, AKUH, Karachi. Observation: Of 855 ovarian tumours 506 (59.18%) were benign and 349(40.81%) malignant. Surface epithelial - stromal tumours comprised 63.50% of all tumours. Benign cystic teratoma was the commonest benign tumour (35.17% of all benign tumours) and serous cystadenocarcinoma was the commonest malignant tumour (33.33% of all malignant tumours). Mucinous cystadenocarcinomas are more common in our population …

Genetic Diversity Of Beta-Thalassemia Mutations In Pakistani Population, B Khateeb, T Moatter, A M. Shaghil, S Haroon, G N. Kakepoto

Department of Pathology and Laboratory Medicine

Background:
beta-thalassemia is one of the most common inherited single gene disorder in Pakistan. It is characterized by reduced or absent beta-globin gene expression resulting in abnormal maturation and survival of red blood cells. Due to high prevalence of this disease in the local population, it has become important for the health care providers to encourage people to utilize laboratory facilities for carrier and prenatal genetic testing.
Objective:
To study the frequency of beta-thalassemia mutations in Pakistani population.
Setting:
A tertiary care teaching hospital.
Methods:
Blood samples of 72 couples and chorionic villus (CV) biopsy specimen collected at the Aga …

Increased Levels Of Multiple Forms Of Dihydrofolate Reductase In Peripheral Blood Leucocytes Of Cancer Patients Receiving Haematopoietic Colony-Stimulating Factors: Interim Analysis, M P. Iqbal, I A. Burney, F Sultana, N Mehboobali, T Siddiqui

Department of Biological & Biomedical Sciences

The precise mechanism whereby granulocytes proliferate when haematopoietic colony stimulating factors (CSFs) are used in neutropenic cancer patients is poorly understood. The purpose of this study was to investigate whether these cytokines bring about leucocyte proliferation by increasing the levels of multiple forms of dihydrofolate reductase (DHFR). Blood samples were collected from 36 cancer patients (25 males and 11 females) with chemotherapy-induced neutropenia. One sample of blood from each patient was obtained before therapy either with CSF, such as granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF) or with placebo, and another one at the time of …

Association Of Epstein Barr Virus (Ebv) With Nasopharyngeal Carcinoma (Npc), S H. Shah, I N. Soomro, S Haroon, T Moatter

Department of Pathology and Laboratory Medicine

Aim:
To observe the frequency of nasopharyngeal carcinoma (NPC) and its association with Epstein Barr Virus (EBV) infection.
Setting:
This study included consecutive cases of nasopharyngeal carcinoma, which were diagnosed in the Department of Pathology at the Aga Khan University Hospital, Karachi in the period of two years (1996-97).
Methods:
These tumors were initially evaluated on H&E stained sections. The tumors showing evidence of keratinization were excluded from the study. The Epstein Barr Virus was detected with the help of Polymerase chain reaction in formalin fixed, paraffin embedded tissue sections.
Results:
During the study period, seventeen cases of nasopharyngeal carcinoma …

Morphological Pattern Of Testicular Tumors, M S. Gill, S H. Shah, I N. Soomro, Naila Kayani, Sheema H. Hasan

Department of Pathology and Laboratory Medicine

Objective:
To find out the mode of presentation, age distribution and the prevalence of various histological subtypes of testicular tumors.
Method:
All consecutive cases of testicular tumors diagnosed in the department of pathology, the Aga Khan University Hospital, Karachi, during the period of eight years (1991-98) were included in this study. Relevant clinical details such as age, clinical presentation and side of involvement of the testis were also recorded, where available.
Results:
During the span of eight years (1991-98), 170 cases of testicular tumors were diagnosed at the Aga Khan University Hospital, Karachi. Most of the tumors were diagnosed in …
