Prediction Of Breast Tumor Size By Ultrasound: A Comparison With Pathology, David Toyis Wanyonyi

Theses & Dissertations

Background: Tumor size is one of the most important prognostic factors in breast cancer and its accurate assessment is critical in planning appropriate treatment. Although histology is often regarded as the definitive way of establishing tumor size, radiological techniques, particularly ultrasonography, are usually relied upon to give an estimate of the tumor size for prognostication and treatment planning. Correlations between mammography, ultrasonography, magnetic resonance imaging (MRI) and pathology size have been performed in different populations with varying results however no prospective study has been done to establish the agreement between sonographic tumor size and histopathological tumor size in our …

Surgical Site Infection Rates In Breast Cancer Surgery At A University Hospital In Nairobi, Kenya, Andrew Nyangau Nyaoncha

A Double-Blind Randomized Controlled Trial Comparing Effectiveness Of 0.2% Topical Nifedipine Versus 0.2% Topical Glyceryl Trinitrate In The Treatment Of Chronic Anal Fissure, Mark Michael Wekundah Siboe

Theses & Dissertations

Background: The medical management of chronic anal fissure varies among clinicians because no single treatment has yet approached an overall healing rate similar to lateral sphincterotomy. However, chemical sphincterotomy has the advantage of not carrying the presumed high risk of faecal incontinence.

Glyceryl Trinitrate is commonly used in our practice with varied response.

This study set out to evaluate the effectiveness of a locally compounded preparation of 0.2% topical Nifedipine in the treatment of chronic anal fissure and to compare the investigational product to 0.2% Glyceryl Trinitrate in overall healing rate and relieving pain.

Design: Single centre, parallel, double-blind …

Androgen Receptor Expression And Associated Clinico-Pathologic Features In Primary Breast Cancer From Kenya, Joshua Kibera Chege

Theses & Dissertations

Introduction: Breast cancer is a heterogeneous group of diseases classified into various subtypes according to clinical, histological and molecular features as well as by the expression of prognostic and predictive biomarkers. New biomarkers are being studied which may be therapeutic targets in various breast cancer subtypes particularly triple-negative breast cancer. Recent studies show that androgen receptor (AR) expression can be used as a prognostic marker and there is evidence that anti-androgen therapy may be beneficial in oestrogen receptor negative breast cancer. Retrospective studies show that patients with breast cancers co-expressing androgen receptor and oestrogen receptor have a favourable prognosis and …

Association Between Parity And Rubella Seropositivity Among Older Reproductive-Age Women, Ibtisam Salim Awadh

Theses & Dissertations

Background: Rubella virus when it infects a non-pregnant adult or child usually causes a mild febrile rash illness. However, infection in the first 12 weeks of pregnancy causes miscarriages, stillbirths or foetal anomalies known as congenital rubella syndrome (CRS). Factors associated with rubella immunity include age and parity. No studies have been done to isolate the association of parity independent of age.

Objectives: To determine the seroprevalence of rubella IgG antibodies among nulliparous and multiparous women of the same age-group attending various clinics in Aga Khan University Hospital, Nairobi,

Design: A cross-sectional study of women attending a tertiary hospital, Nairobi, …

Hospital-Acquired Malnutrition In Children In A Tertiary Care Hospital, Del-Rossi Sean Quadros

Theses & Dissertations

Introduction: Hospital-acquired Malnutrition occurs as a result of reduction in food intake, increased dietary loss and/or increased calorie requirements as a result of disease-induced high catabolic state. A child's nutritional status often deteriorates after admission to the hospital resulting in longer duration of hospital stay and increased risk of complications, which also increases treatment cost. Hospital-acquired Malnutrition is usually assessed using anthropometric measurements and/or serum pre-albumin.

Objectives: This study sought to investigate the incidence of Hospital-acquired Malnutrition using anthropometric measurements and to determine diagnostic utility of serum pre-albumin in predicting weight change. A secondary objective was to identify …

The Heart Weight–Body Weight Coefficient In Kenyans Aged 14 Years And Above, Mbayah Etabale

Theses & Dissertations

Background: The heart size has traditionally been assessed using absolute reference weights. But the heart weight (HW) has been shown to depend on one’s body size hence a better measure is the ratio of the HW to the body weight (BW) – the HW-BW coefficient. Initially noted to be 0.43% and 0.40% in males and females respectively, recent studies have shown an increase of up to 0.51%.

Objective: To determine the HW-BW coefficient in Kenyans aged 14 years and above.

Methods: One hundred and four deceased Kenyans aged 14 years and above, with no heart or chronic lung disease, were …

Racecadotril For The Treatment Of Severe Acute Watery Diarrhoea In Children Admitted To The Kenyatta National Hospital - A Randomised Double Blinded Placebo Controlled Trial, Jaspreet Singh Gharial

Theses & Dissertations

Background: Diarrhoeal disease is the second most common cause of death in children under 5 years of age in Kenya. Treatment with Oral Rehydration Solution (ORS), elemental zinc and continued feeding (as recommended by the World Health Organisation) led to a significant reduction in mortality in the 1970s and 1980s, which has slowed since then. Adjunctive treatments have however, not gained much popularity either due to modest improvements in morbidity and mortality or unacceptable adverse effect profiles. Racecadotril, an enkephalinase inhibitor, has been used for over 2 decades in parts of Europe but is only recently gaining recognition in …

The Prevalence Of Malaria And Assessment Of The Uptake Of Malaria Prevention Measures In Blood Donors In Two Regional Blood Transfusion Centres In Kenya, Valerie Magutu

Theses & Dissertations

Transfusion transmitted malaria is one of the most common transfusion transmissible infections and is a threat to blood safety and malaria control in Sub-Saharan African countries where malaria is endemic. The majority of healthy adults living in malaria endemic areas have some degree of immunity to the disease and an asymptomatic low-level parasitaemia is known to exist in a subset of this population. Blood donors recruited from the population are screened using a donor-selection criteria that includes age, weight, self-declared well-being and measurement of vital signs but not history of recent malaria infection or treatment. The Kenya National Blood Transfusion …

Psychosocial Factors Associated With Exclusive Breastfeeding Among Pregnant Women On Follow Up In A Tertiary Maternity Hospital, Cornelia Akinyi Ochola

Theses & Dissertations

Introduction: Exclusive breastfeeding during the first six months of life is the ideal form of infant feeding. Health benefits of exclusive breastfeeding to infant and mother are well documented in literature. Despite this, the rate of exclusive breastfeeding in the first six months of infants‘ life in Kenya remains low. National nutrition strategy for maternal, infant and young child has set its 2017 target for exclusive breastfeeding at 80% from 32%. To achieve this target, new strategies are needed to complement current exclusive breastfeeding initiatives. Application of theory of planned behaviour model was used to determine the psychosocial factors associated …
