Socio-demographic, pattern of presentation and management outcome of breast cancer in a semi-urban tertiary health institution.

INTRODUCTION: breast cancer is the most common malignancy in females worldwide and a major cause of cancer-related deaths in both developing and developed countries. The objective of this study was to determine the socio-demographics, pattern of presentation and management outcome of breast cancer patients. METHODS: clinical records of confirmed breast cancer patients between January 2011 and December 2015 at the Ekiti State University Teaching Hospital, Ado-Ekiti, Nigeria were reviewed. RESULTS: eighty two breast cancer patients were seen. Their ages ranged from 26-95 years (mean 48.9 ± 14.9 years, median 47.5 years). Eighty one (98.8%) were females and the majority (65.4%) were premenopausal. The peak age of incidence was in the 4th decade. All patients presented with breast lump with mean duration of 9.49±6.1 months and size ranging from 2 to 16cm (mean 7.9±3.4 cm). Ten (12.2%) patients presented early, 61 (74.4%) were locally advanced while 11 (13.4%) had distant metastases. Fifty one (62.2%) patients had mastectomy. Only 38 (46.3%) patients completed six courses of chemotherapy. None had immunohistochemistry but they all routinely took tamoxifen. Only 4 (4.9%) had radiotherapy. Nineteen (23.2%) died within a year of presentation. The follow-up period ranged between 1 and 44 months (mean, 10.3 months). Thirty one (37.8%), 19 (23.2%) and 8 (9.8%) patients were seen during the first, second and third year of follow up respectively. CONCLUSION: breast cancer mostly affects young premenopausal women presenting in advanced stage in our setting. The generally poor outcome is not unconnected with late presentation and inadequate diagnostic and treatment facilities.

How COVID-19 pandemic is changing the Africa's elaborate burial rites, mourning and grieving.

There are diverse burial rites in Africa which have been practiced for decades depending on the deceased place of origin, culture, religion and the position held in the community. Unlike the developed countries where burials are usually conducted as private ceremonies, funerals in Africa are elaborate and are usually public ceremonies involving the entire members of families, friends and well-wishers. Religion and culture are usually the deciding factors when decisions are made on how the deceased should be buried but generally cremation is not commonly practiced in Africa. COVID-19 pandemic was generally accepted to originate from Wuhan in China and this pandemic has extended to Africa. Most countries in Africa responded to the COVID-19 pandemic by adopting the same strategies used by the Western countries in curbing the spread of the virus through the imposition of restrictions on movements, lock down and the introduction social distancing rules which are align to Africa way of living. These control strategies had put a lot of pressures on the weak mortuary services in Africa, altered the traditional methods of observing burial rites, mourning and grieving. COVID-19 pandemic has changed the various traditional ways Africans mourn grief and bury their love one. The dead bodies of people suspected or confirmed to have COVID-19 should be treated with respect, ensuring the rights of the dead to a dignifying burial are upheld while adhering to standard precautions including use of appropriate PPEs, hand hygiene before and after the burial procedure.

Aspirin-Induced Gastric Lesions Alters EGFR and PECAM-1 Immunoreactivity in Wistar Rats: Modulatory Action of Flavonoid Fraction of Musa Paradisiaca.

AIM: In this study, Epithelial Growth Factor Receptor and Platelet Endothelial Cell Adhesion Molecule-1 were localised to investigate the healing effects of a flavonoid-rich fraction of M. paradisiaca fruit in the gastric corpus of Wistar rats following aspirin-induced gastric lesion. MATERIALS AND METHODS: Mature, unripe fruits of M. paradisiaca were peeled; air dried, pulverised, extracted with 70% methanol, concentrated and partitioned. Ninety male Wistar rats were randomly assigned into 6 groups of 15 rats each. The gastric lesion was induced in groups B, C, D, E and F rats by administration of 400 mg/kg aspirin in distilled water. Group A received distilled water. After 24 hours, flavonoid fraction of M. paradisiaca was administered to groups C, D and E at 100, 200 and 400 mg/kg respectively for 21 days. Group F rats received omeprazole at 1.8 mg/kg for 21 days. Five rats from each group were anaesthetized with ketamine on days 14, 21 and 28. Gastric tissues were excised and fixed in Neutral buffered formalin. This was followed by paraffin wax embedding method and sections stained with haematoxylin and eosin and for immunolocalisation of EGFR and PECAM-1. Data were analysed using descriptive and inferential statistics. RESULTS: There was a significant difference in the ulcer index in the corpus of control and treated rats throughout the experimental period (p = 0.0001). H&E stained sections showed a gradual restoration of the epithelial lining in the treated groups. Immunohistochemical examination showed that M. paradisiaca significantly increased (p < 0.05) reactivity for both EGFR and CD31 across the treatment groups. CONCLUSION: The efficacy of Musa paradisiaca in attenuating the damaging effects of aspirin on the gastric mucosa was observed as there was a significantly increased reactivity for EGFR and PECAM-1 in the gastric corpus in a dose-dependent manner.

The pathogenicity of Staphylococcus epidermidis on the intestinal organs of rats and mice: an experimental investigation.

BACKGROUND: Staphylococcus epidermidis is the most frequently isolated species of the coagulase negative staphylococci from human stool. However, it is not clear how its presence in the gut affects the cellular structures and functions of this organ. In this study therefore, the pathogenicity of strains of S. epidermidis which were isolated from the stool samples of apparently healthy children was investigated in mice and rats. METHODS: The albino mice (22-30 g) and albino rats (100-155 g) of both sexes were infected orally and intraperitoneally with graded doses of the bacteria and subjected to behavioral and histopathological examinations. RESULTS: Acute infection in these animals caused temporary behavioural changes as shown by restlessness and abdominal stretchings but did not result in death even at a dosage of 2 × 109 cfu/kg. Daily administration of the same dose for 14 days resulted in the death of 11 out of 21 (52.4%) mice. Histopathological examination of the affected organs showed congestions, aggregations and multinucleated hepatocytes in the liver, infiltration of the kidney tubule interstitial by chronic inflammatory cells, coagulative necrosis of the kidney, spleen, intestine and stomach cells as well as marked stroma fibrosis of the spleen. Coagulative necrosis of cells was the most frequently occurring pathological alteration. Lethality and pathological effects reflected the virulence factors expressed by the organism which are biofilm formation, haemagglutination properties and capsule production. CONCLUSIONS: The results indicate that strains of S. epidermidis colonising the gut can cause serious pathological changes on certain organs such as kidney, liver, intestine, stomach and spleen which, depending on their severity, could be fatal.
