Analysis Of Terminal Duct Lobular Unit Involution In Luminal, Her-2enriched And Triple Negative Breast Cancer Subtypes, Joseph Nyaguti Kiwinga

Theses & Dissertations

Introduction: The terminal duct lobular unit (TDLU) of the breast is the most common origin of most breast cancers (BC). With increasing age and menopause, physiologic involution of TDLU occurs with a reduction in both the number and size of the lobules. Reduced TDLU involution is associated with a higher mammographic breast density (MBD) which by itself is a strong breast cancer risk factor. Recent studies have shown that TDLU involution is associated with a reduced risk of breast cancer and involution also differs with molecular subtypes of BC.

Studies have shown that the etiology, pathogenesis and prognosis of the …

Von Willebrand Disease Among Women Of African Descent Attending The Aga Khan University Hospital Nairobi, With Menorrhagia, Angela Nabutilu Munoko

Theses & Dissertations

Introduction: Von Willebrand Disease (VWD) is the most common heritable bleeding disorder with equal prevalence reported across the races. Women are more likely to present with excessive bleeding due to menstruation and child bearing. Studies have found that 5-24% of women presenting with menorrhagia have VWD.

Glycogen Storage Diseases-Time To Flip The Outdated Diagnostic Approach Centered On Liver Biopsy With The Molecular Testing, Sibtain Ahmed, Bushra Afroze

Department of Pathology and Laboratory Medicine

The glycogen storage diseases (GSDs) are a group of inherited metabolic disorders that result from a defect in any one of several enzymes required for either glycogen synthesis or glycogen degradation. The traditional diagnostic approach is based on the invasive hepatic or muscle biopsies, which are neither cost effective nor convenient. Molecular (gene testing) has emerged over the course of past few years as a robust alternative diagnostic tool, which not only confirms the diagnosis of GSDs but also clearly differentiates the types of GSDs allowing the initiation of the type-specific appropriate treatment for the particular type of GSDs. The …

Sensitivity analysis for factors outside the health sector influencing health outcomes was conducted to refine …

Etiologies Of Lower Respiratory Tract Infections Among Adult Patients Presenting To A Tertiary Institution In Nairobi, Mary Achakolong

Theses & Dissertations

Background: Lower respiratory tract infections continue to contribute significantly to morbidity and mortality across all age groups globally. Viral pathogens in isolation or as co-infections are an important cause of pneumonia and associated with several life threatening syndromes that warrant appropriate and timely lifesaving diagnosis. Many viral respiratory infections demonstrate substantial regional and seasonal variations which are poorly understood. In addition, there are very few studies in sub-Saharan Africa that have examined the role of viruses as causes of community acquired pneumonia. The availability of molecular techniques such as multiplex PCR that are much more sensitive than traditional methods and …

Perceptions Of Surgeons On Surgical Antibiotic Prophylaxis Use At Aga Khan Hospital, Dar Es Salaam., Elizabeth Elibariki Mmari

Theses & Dissertations

Introduction: Surgical site infections are a major cause of morbidity and mortality among operated patients. The use of antibiotic prophylaxis in prevention and reduction of incidence of surgical site infection is widespread. In spite of the accessibility of universal and national guidelines for surgical prophylaxis, recent studies surveying the present routine of prophylaxis have demonstrated overutilization of a wide range antibacterial medications for a single patient. Few studies have shown qualitatively factors influencing this, and perceptions of surgeons on surgical antibiotic prophylaxis use. Unfortunately, none of these studies have been done in Tanzania.

Objective: To describe the perceptions of surgeons …
