BRCA1 and BRCA2 mutations and their clinical relevance in selected women diagnosed with triple-negative breast cancer in Kenya: a descriptive cross-sectional study.

Introduction: triple-negative breast cancer (TNBC) is a heterogeneous breast cancer type with a poor prognosis. About 25% of TNBC patients carry breast cancer susceptibility genes 1 and 2 (BRCA1 and BRCA2) mutations. Screening for BRCA mutations would facilitate early detection and initiation of personalized therapy, thus improving prognosis.

Cytomorphological patterns of breast lesions among women with palpable breast lumps attending select teaching and referral hospitals in Kenya: a descriptive cross-sectional study.

Introduction: breast lumps account for a greater number of lesions in women attending surgical clinics in the developing world. Breast cancer which mostly presents as a breast lump is the leading cancer in Kenya, with an incidence of 12.5%.

Utility of p16INK4a expression for the interpretation of uterine cervical biopsies in Kenya.

Introduction: histologic interpretation of hematoxylin and eosin-stained cervical biopsies is subject to substantial discordance among pathologists. Immunohistochemical staining for p16INK4a can reduce inter-observer disagreement. We did a cross-sectional study to evaluate the utility of p16INK4a staining in the assessment of cervical biopsies in Nairobi, Kenya.

Acceptability and feasibility of inter-related activities to improve agency among African district health managers: A four-country study.

District health managers (DHMs) lead and manage Ministry of Health programmes and system performance. We report on the acceptability and feasibility of inter-related activities to increase the agency of DHMs in Kenya, Nigeria, South Africa and Uganda using a cross-sectional rapid appraisal with 372 DHMs employing structured questionnaires. We found differences and similarities between the countries, in particular, who becomes a DHM.

The potential of RNA as a target for national screening of pre-cancer.

Whole national screening of pre-cancer is done only in some few countries, dominated by The Netherlands, Denmark, UK, Norway and Finland. These national screenings are done combining national cancer registry, national public health and national medical bodies or hospitals. Until some few years ago national screening was only done using morphological or visual methods or technology.

Task Sharing and Shifting to Provide Pathology Diagnostic Services: The Kenya Fine-Needle Aspiration Biopsy Cytology and Bone Marrow Aspiration and Trephine Biopsy Training Program.

Purpose: Fine-needle aspiration biopsy (FNAB) cytology is a simple, inexpensive, and accurate diagnostic test for benign, infectious, and malignant lesions of the breast, thyroid, lymph nodes, and other organs. Similarly, bone marrow aspiration and trephine (BMAT) biopsy procedures are relatively simple and inexpensive techniques that are important for diagnosing and monitoring many hematologic diseases including leukemias and lymphomas. However, the scarcity of pathologists in Kenya limits patient access to these simple diagnostic tests.

Curriculum and training needs of mid-level health workers in Africa: a situational review from Kenya, Nigeria, South Africa and Uganda.

Background: Africa's health systems rely on services provided by mid-level health workers (MLWs). Investment in their training is worthwhile since they are more likely to be retained in underserved areas, require shorter training courses and are less dependent on technology and investigations in their clinical practice than physicians. Their training programs and curricula need up-dating to be relevant to their practice and to reflect advances in health professional education.

Esophageal cytology sponge diagnostic test results in kenyatta national referral hospital, kenya.

Objective: To describe the cytological findings of the esophagus using sponge cytology as a triage test in patients referred for esophageal endoscopy at Kenyatta National Hospital.

Study Design: A cross-sectional descriptive study was undertaken to obtain specimens from the esophagus for cytological evaluation using a sponge. The cellular yield and pattern of esophageal cytological findings was described by cytopathologists using the Bethesda system.

The prevalence of human papillomavirus infection in Mombasa, Kenya.

Objectives: A human papillomavirus (HPV) prevalence survey was done in Mombasa, Kenya, to improve the knowledge of HPV prevalence and genotype distribution in sub-Saharan African countries overall, and in women of different ages.

Methods: HPV prevalence was assessed using PCR in women older than 15 years attending family planning and mother-child care services.

Results: Among 496 women, HPV prevalence was high (42.

Progesterone, estradiol and their receptors in leiomyomata and the adjacent normal myometria of black Kenyan women.

The contents of progesterone and oestrogen, and their respective receptors in uterine leiomyomata and adjacent normal myometrial tissue in indigenous black women in Kenya were studied. A random selection of twenty women undergoing hysterectomy for uterine fibroids at Kenyatta National Hospital was used for the studies. The myometria contained higher levels of E(2 ) (181% : P < 0.

Routine assessment of hormonal receptor and her-2/neu status underscores the need for more therapeutic targets in Kenyan women with breast cancer.

Objective: To report the expression of estrogen receptors, progesterone receptors and human epidermal growth factor receptor (Her-2/neu) in 158 Kenyan women with breast cancer and correlation with other prognostic indicators in this high-risk group. This study stressed the importance of routine assessment of the steroid receptors and Her-2/neu as a mode of therapeutic selection of patients for antihormonal or targeting monoclonal antibody (Herceptin) therapy, directed at the juxtamembrane domain of Her-2/neu protein in the developing countries such as Kenya.

Study Design: The study population consisted of 158 female patients with histologically confirmed breast carcinoma seen at the pathology department of The Nairobi Hospital.

Distribution of human papillomavirus in a family planning population in nairobi, kenya.

Background: In sub-Saharan Africa, cervical cancer is the leading cancer among women. The causative role of different human papillomavirus (HPV) types in cervical cancer is established, but the distribution of HPV types within this region is largely unknown.

Goal: The goal was to study the distribution of HPV among family planning clinic attendees in Nairobi, Kenya.
