Section of Neurosurgery

Background: After 2 decades of focused efforts to eradicate polio, the impact of eradication activities on health systems continues to be controversial. This study evaluated the impact of polio eradication activities on routine immunization (RI) and primary healthcare (PHC).
Methods: Quantitative analysis assessed the effects of polio eradication campaigns on RI and maternal healthcare coverage. A systematic qualitative analysis in 7 countries in South Asia and sub-Saharan Africa assessed impacts of polio eradication activities on key health system functions, using data from interviews, participant observation, and document review.
Results: Our quantitative analysis did not find compelling evidence of widespread and …


Leishmania Donovani Bodies In Bone Marrow, Natasha Ali, Shabneez Hussain Oct 2014

Leishmania Donovani Bodies In Bone Marrow, Natasha Ali, Shabneez Hussain

Department of Pathology and Laboratory Medicine

We report a case of a 5-year-old female, resident of Afghanistan, who presented with fever and massive splenomegaly. Bone marrow revealed Leishmania donovani bodies (LD bodies) in macrophages characterized by a kinetoplast and characteristic double dot appearance. She was diagnosed as visceral leishmaniasis which is transmitted by sandflies (Phlebotomus).

Chromosomal Abnormalities In Primary Myelodysplastic Syndrome, Anila Rashid, Mohammad Khurshid, Usman Shaikh, Salman Adil

Department of Pathology and Laboratory Medicine

Objective: To determine the frequency of cytogenetic abnormalities in patients diagnosed as primary myelodysplastic syndrome (MDS) using conventional karyotyping. Study Design: Case series. Place and Duration of Study: The Clinical Laboratory, The Aga Khan University Hospital, Karachi, between January 2006 - June 2012. Methodology: Patients of all ages and either gender who fulfilled WHO criteria for MDS were included. Cytogenetic analysis was conducted at the time of diagnosis. Patients who had secondary MDS were excluded from analysis. Chromosome identification and karyotype description was done according to the International System for Chromosome Nomenclature (ISCN, 1995) and described as frequency percentage. Results: …

Mycobacterium Tuberculosis Central Asian Strain (Cas) Lineage Strains In Pakistan Reveal Lower Diversity Of Miru Loci Than Other Strains, Asho Ali, Zahra Hasan, Sana Jafri, Raunaq Inayat, Rumina Hasan Jun 2014

Mycobacterium Tuberculosis Central Asian Strain (Cas) Lineage Strains In Pakistan Reveal Lower Diversity Of Miru Loci Than Other Strains, Asho Ali, Zahra Hasan, Sana Jafri, Raunaq Inayat, Rumina Hasan

Department of Pathology and Laboratory Medicine

Mycobacterium tuberculosis (MTB) Central Asian Strain (CAS) lineage strains are predominant in South Asia. Mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) typing is an effective way of determining genetic diversity of strains. A maximum of 24 loci-based MIRU-VNTR typing can be used, however, it is important to investigate the relevance of specific MIRU loci for regional strains for more cost-effective MIRU typing. MIRU-VNTR typing was performed on MTB strains from Pakistan. Strains were comprised of CAS (n=113) and non-CAS lineages (n=87) - both multi-drug resistant (MDR) and drug susceptible. Hunter Gaston Discriminatory Index (HGDI) for each MIRU loci …


Galectin-1 In Early Acute Myocardial Infarction, Suhail Al-Salam, Satwat Hashmi Jan 2014

Galectin-1 In Early Acute Myocardial Infarction, Suhail Al-Salam, Satwat Hashmi

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most serious manifestation of coronary artery disease and the cause of significant mortality and morbidity worldwide. Galectin-1(GAL-1), a divalent 14.5-kDa protein, is present both inside and outside cells, and has both intracellular and extracellular functions. Hypoxia inducible factor-1 alpha (HIF-1α) is a transcription factor mediating early and late responses to myocardial ischemia. Identification of the pattern of expression of GAL-1 and HIF-1α in the heart during the first 24 hours following acute MI will help in understanding early molecular changes in this event and may provide methods to overcome serious complications. Mouse model of MI …


Gossypiboma Diagnosed Fifteen Years After A Cesarean Section: A Case Report, Abdul Rehman, Noor Ul-Ain Baloch, Muhammad Awais Jan 2014

Gossypiboma Diagnosed Fifteen Years After A Cesarean Section: A Case Report, Abdul Rehman, Noor Ul-Ain Baloch, Muhammad Awais

Department of Biological & Biomedical Sciences

Gossypiboma, a retained surgical sponge, is a rare complication following any surgical procedure and is primarily a result of human error. Such patients often have vague clinical presentations and the diagnosis often comes as a surprise. We present the case of a 40-year-old woman who had a long-standing history of lower abdominal discomfort. She was diagnosed with a gossypiboma fifteen years after a cesarean section. All general physicians, surgeons and radiologists must be aware of this rare but clinically significant entity.


Pleomorphic Lobular Carcinoma Of The Male Breast With Axillary Lymph Node Involvement: A Case Report And Review Of Literature, Muhammad Nauman Zahir, Khurram Minhas, Munira Shabbir-Moosajee Jan 2014

Pleomorphic Lobular Carcinoma Of The Male Breast With Axillary Lymph Node Involvement: A Case Report And Review Of Literature, Muhammad Nauman Zahir, Khurram Minhas, Munira Shabbir-Moosajee

Department of Pathology and Laboratory Medicine

Background: Carcinoma of the male breast is responsible for less than 1% of all malignancies in men but the incidence is rising. Invasive ductal carcinoma is the most common histological subtype while invasive lobular carcinoma is responsible for only 1.5% of the total cases of which pleomorpic lobular carcinoma is an extremely rare variant. We report the case of a gentleman with node positive, pleomorphic lobular carcinoma of the breast.
Case Presentation: An elderly gentleman with a past history of type 2 diabetes and long term ethanol use presented to us with a self-discovered palpable lump in the left breast. …

Ovarian Sex Cord Stromal Tumours In Children And Young Girls - A More Than Two Decade Clinicopathological Experience In A Developing Country, Pakistan, Saroona Haroon, Romana Idrees, Aleena Zia, Aisha Memon, Saira Fatima, Naila Kayani

Department of Pathology and Laboratory Medicine

Background: Ovarian sex-cord stromal tumours (SCST) are rare, and relatively infrequent in children. These have to be distinguished from more common germ cell tumors in children and also from benign epithelial neoplasms.
Objectives: The purpose of our study was to report the clinical and pathological findings in young patients with these tumours in our population.
Material and Methods: The present observational cross-sectional study included all subjects SCST, in Aga Khan University Hospital Histopathology Laboratory, Karachi, Pakistan, from January 1992 till July 2013.
Results: Of the total of 513 SCSTs presented during the study period, 39 fulfilled inclusion criteria and were …


Culturable Aerobic And Facultative Anaerobic Intestinal Bacterial Flora Of Black Cobra (Naja Naja Karachiensis) In Southern Pakistan, Junaid Iqbal, Mehwish Sagheer, Nazneen Tabassum, Ruqaiyyah Siddiqui, Naveed Ahmed Khan Jan 2014

Culturable Aerobic And Facultative Anaerobic Intestinal Bacterial Flora Of Black Cobra (Naja Naja Karachiensis) In Southern Pakistan, Junaid Iqbal, Mehwish Sagheer, Nazneen Tabassum, Ruqaiyyah Siddiqui, Naveed Ahmed Khan

Department of Biological & Biomedical Sciences

Using morphological analysis and biochemical testing, here for the first time, we determined the culturable gut bacterial flora (aerobes and facultative anaerobes) in the venomous Black Cobra (Naja naja karachiensis) from South Asia. The findings revealed that these snakes inhabit potentially pathogenic bacteria including Serratia marcescens, Pseudomonas aeruginosa, Shewanella putrefaciens, Aeromonas hydrophila, Salmonella sp., Moraxella sp., Bacillus sp., Ochrobactrum anthropi, and Providencia rettgeri. These findings are of concern, as injury from snake bite can result in wound infections and tissue necrosis leading to sepsis/necrotizing fasciitis and/or expose consumers of snake meat/medicine in the community to infections.
