A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Medicine in Diagnostic Radiology Johannesburg, 2019 / INTRODUCTION Breast cancer is one of the leading causes of cancer deaths worldwide. Triple negative breast Cancer (TNBC) is an aggressive subtype, commonly described as presenting at a younger age, in women of African descent and in low socioeconomic groups. Commonly it demonstrates benign imaging features making diagnosis a challenge. Early detection and treatment is imperative. AIM To determine the common imaging features of TNBC in South Africa. METHOD A retrospective study was conducted at a tertiary institution in South Africa. the study population included all biopsy proven TNBC patients presenting between 01/01/2012 – 30/06/2016. All the initial mammograms were re-read by three independent radiologists using a data collection sheet. Illegible or incomplete reports were excluded from the study. RESULTS In our population, TNBC commonly presented in African women with an average age of 54.2 and range 25-95 years, with 47% being pre-menopausal. Typical mammographic features were an oval (27%) or irregular (27%) shaped mass with well circumscribed margins (33%). Our lesions were much larger than those reported in the literature (1). Global asymmetry and architectural distortion were commonly associated features. On ultrasound, the lesions were mostly irregularly shaped (56%) with spiculated borders (29%) and hypoechoic (80%) with axillary adenopathy (81%). CONCLUSION The majority of our patient population presented with a clinically palpable mass, that was larger and had more aggressive features than usually described in the literature. This can be attributed to delayed presentation, due to numerous factors. In order to improving the detection rate and reduce mortality, education and screening programs play a major role. / E.K. 2019

Purpose: The objectives of this pilot study for women breast cancer survivors with lymphedema was 1) to evaluate recruitment rates, retention rates, adherence to Bowenwork (a noninvasive complementary therapy involving gentle muscle movements), home exercises, safety and comfort; 2) determine the effect of Bowenwork on quality of life (QOL), functional status, perceived pain, range of motion (ROM), arm/ankle circumference (to assess for localized and systemic changes). Methods: Participants received 4 Bowenwork sessions with home exercises. Initial and post assessments included QOL, functional status, and pain. ROM, arm/ankle circumference and pain measures were recorded before each session. Results: Twenty-one women enrolled in the study; 95% completion; adherence 100%; home exercises 95%; no adverse events. The intervention improved mental health (SF-36-MCS); breast cancer-related functional (FACT-B); increased ROM; reduced arm circumferences. P value set at <0.05. Conclusions: The Bowenwork intervention was safe and acceptable for women breast cancer survivors with lymphedema.

A thesis submitted to the Faculty of Health Sciences, University of the Witwatersrand, in fulfilment of the requirements for the degree of Doctor of Philosophy Johannesburg, February 2015 / Androgen Insensitivity Syndrome (AIS) is an X-linked disorder caused by mutations in the androgen receptor (AR) gene. The phenotype is variable and ranges from a complete feminine syndrome to simple gynecomastia. The phenotypes are described in terms of complete, partial and mild forms (CAIS, PAIS and MAIS). We describe novel and previously reported (recurrent) mutations in the AR gene for a family in which segregation of breast cancer (BC) and gynecomastia/MAIS is present. Methods: We studied a family of 16 members spanning four generations. Based on the presentation of symptoms, the family was divided into affected, unaffected, and control groups. Seven patients (six males diagnosed with MAIS and one female diagnosed with BC) formed the affected group, four genetically related individuals (two males and two females) formed the unaffected group and five genetically unrelated family members (one male and four females) served as controls. In each of these individuals, PCR amplification, cloning and the sequencing of exon 1 were carried out. Exons 2-8 were sequenced directly after PCR amplification. Exon 1 (CAG)n and (GGN)n repeats were classified according to their length: short (S) (n<23), long (L) (n>23) and wild type (WT) (n=23). Results: Part 1-The (CAG)n repeats varied among individuals and generations. In the 2nd generation, the unaffected male was S and the control female was WT. In the 3rd generation, three affected males were S, 2 of the controls were WT, one control was L and the other S. In the 4th generation, the 4 affected individuals were L, 1 of the unaffected was WT and the other 2 unaffected were L. Part 2- The (GGN)n variations also differed among individuals and generations. In the 2nd generation, the unaffected male and the control were S. In the 3rd generation, all three affected family members were S and among the controls, 1 was WT, 1 was L and 2 were S. In the 4th generation, 3 of the affected were S and one was WT and among the 3 unaffected, 2 were S and one was WT. Part 3- 30 unreported (novel) mutations as well as 13 recurrent (previously reported) mutations in exon 1 of the AR gene were identified. 17 novel and 5 reported mutations were identified in the affected group, 8 novel and 5 reported mutations, including one premature stop codon mutation, were identified in the related unaffected group and 7 novel and 4 reported mutations were found in the controls. Of the above-mentioned mutations, four mutations were identified in the activation function-1 (AF-1) domain of exon 1 in 4 members (3 affected: M-2, F-1 and 1 unaffected: F-1) of the family. All the point mutations identified were somatic in nature and were present in heterogeneous form i.e wild and mutant (mixture) as determined by cloning. The analysis of exons 2 through 8 revealed completely WT sequences. Conclusions: The (CAG)n and (GGN)n repeat analysis showed an indeterminate association with MAIS and BC in the family. Generation specific patterns of (CAG)n were detected and suggest generation specific modulation of the AR. Novel mutations including AF-1 region mutations were identified in exon 1. The disruption of the AF-1 domain may affect the transactivation activity of the AR.
