Sino - nasal surgery in the sub-Saharan Africa: A critical appraisal

Background: Sino - nasal surgery poses a great challenge to practicing ear, nose and throat surgeons in the sub- Saharan Africa where facilities are inadequate and most patients are distantly located from the few hospitals available in this region. Method: A retrospective study of 79 patients who had nasal and paranasal sinuses surgery at the university of Maiduguri teaching hospital (UMTH) between January 1997 to December 2001. Results: The most common indication for surgery was infection/allergy in 49 (62%) patients, followed by tumours in 16 (22.3%) patients. In the infection/allergy subgroup, intranasal antrostomy and nasal polypectomy were the most common procedures done constituting 63.3% and 32.7% respectively. Nasal surgeries as a result of trauma and congenital anomalies were quite few. Conclusion: This rather low figure is unexpected considering the few available services in this region. Therefore health education and community awareness on health matters should be stressed. Key Words: Nasal surgery, intranasal antrostomy, nasal polypectomy Annals of African Medicine Vol.3(2) 2004: 66-6

Metallointercalator [Ru(dppz)2(PIP)]2+ Renders BRCA Wild-Type Triple-Negative Breast Cancer Cells Hypersensitive to PARP Inhibition

There is a need to improve and extend the use of clinically-approved poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi), including for BRCA wild-type triple-negative breast cancer (TNBC). The demonstration that ruthenium(II) polypyridyl complex (RPC) metallo-intercalators can rapidly stall DNA replication fork progression provides the rationale for their combination alongside DNA damage response (DDR) inhibitors to achieve synergism in cancer cells. The aim of the present study was to evaluate use of the multi-intercalator [Ru(dppz)2(PIP)]2+ (dppz = dipyrido[3,2-a:2′,3′-c]phenazine, PIP = (2-(phenyl)imidazo[4,5-f][1,10]phenanthroline, Ru-PIP) alongside the PARP inhibitors (PARPi) olaparib and NU1025. Cell proliferation and clonogenic survival assays indicated a synergistic relationship between Ru-PIP and olaparib in MDA-MB-231 TNBC and MCF7 human breast cancer cells. Strikingly, low dose Ru-PIP renders both cell lines hypersensitive to olaparib, with a 300-fold increase in olaparib potency in TNBC; the largest non-genetic PARPi enhancement effect described to date. Negligible impact on the viability of normal human fibroblasts was observed for any combination tested. Increased levels of DNA double-strand break (DSB) damage and olaparib abrogation of Ru-PIP activated pChk1 signalling is consistent with PARPi-facilitated collapse of Ru-PIP-associated stalled replication forks. This results in enhanced G2/M cell-cycle arrest, apoptosis and decreased cell motility for the combination treatment compared to single-agent conditions. This work establishes that an RPC metallo-intercalator can be combined with PARPi for potent synergy in BRCA-proficient breast cancer cells, including TNBC

Hepatitis b, c and hiv serological markers in children with sickle cell anaemia in a tertiary hospital, Gusau, North-Western Nigeria

Sickle Cell Anaemia patients are considered to be among the high-risk groups for hepatitis B and C viral infections. These viruses and HIV share common routes of transmission and similar risk factors and their infections coexist. Objective: This study was aimed at determining the seroprevalence of hepatitis B, C and HIV viral markers of infections in children with SCA. Methodology: A cross sectional Hospital based study conducted on 89 confirmed SCA Children aged 6 months – 13 years in steady state attending Haematology Clinic in a Specialist Hospital Gusau from July 2017 to March 2018. Approval for the study was obtained from the Research and Ethics Committee of the Hospital. The age, gender, history of blood transfusion, traditional scarification, uvulectomy, circumcision and immunization of the subjects were recorded. Serological test was carried out to determine the prevalence of hepatitis B, C and HIV using the viral markers and HIV 1& 2 rapid test kits. Results: Eighty-nine subjects were recruited with 46(51.7%) males and 43(48.3%) females. The mean age was 5.06 ±3.4 years. The seroprevalence of HBsAg, HBsAb, HBcAb, HBeAg, HBeAb, AntiHCV and HIV 1& 2 were 3(3.4%), 3(3.4%), 5(5.7%), 1(1.1%), 6(6.9%) and 0% respectively. No co-infection among the studied subjects. There is no significant difference in the age or gender distribution and seroprevalence of the viruses among SCA children. p = > 0.05 Conclusion: Hepatitis C infection is found to be high as opposed to Hepatitis B which is lower among SCA Children in this community

Life experiences and coping mechanisms among breast cancer patients in an urban Malaysian hospital : a qualitative study

Breast cancer is top-ranking cancer that affects the quality of life among women in Malaysia. Although it is very difficult to define the quality of life (QoL) precisely, it has a broad concept that affects global life satisfaction, which includes good health, adequate housing, employment, personal and family safety, interrelationships, education, and leisure pursuits. In this study, we aimed to discuss the life changes upon being diagnosed with breast cancer and their perception of social support. We also discussed the spirituality factor in patients’ coping mechanism with their health condition. This study was carried out using a purposive sampling method. The perception of social support, quality of life, and religiosity factor is discussed through the perspectives of nine breast cancer patients with an interview consisting of semi-structured questions. Basic interpretive qualitative methodology was applied to analyse the perception of social support and religiosity factor as a coping mechanism. The results showed that all the breast cancer patients reported good social support from family and friends except for one patient. Five themes were identified, namely patterns of life, supportive atmosphere, decision making and confidence, expectation, as well as psychological defences and spirituality. Seven out of nine patients reported that their religion helped them to cope with the disease by maintaining self-esteem, providing a sense of meaning and purpose, giving emotional comfort, and providing a sense of hope. In conclusion, social support and religious factor are very important in the lives of breast cancer patients in dealing with their health condition

Presenting features and long-term effects of growth hormone treatment of children with optic nerve hypoplasia/septo-optic dysplasia

<p>Abstract</p> <p>Background</p> <p>Optic nerve hypoplasia (ONH) with/or without septo-optic dysplasia (SOD) is a known concomitant of congenital growth hormone deficiency (CGHD).</p> <p>Methods</p> <p>Demographic and longitudinal data from KIGS, the Pfizer International Growth Database, were compared between 395 subjects with ONH/SOD and CGHD and 158 controls with CGHD without midline pathology.</p> <p>Results</p> <p>ONH/SOD subjects had higher birth length/weight, and mid-parental height SDS. At GH start, height, weight, and BMI SDS were higher in the ONH/SOD group. After 1 year of GH, both groups showed similar changes in height SDS, while weight and BMI SDS remained higher in the ONH/SOD group. The initial height responses of the two groups were similar to those predicted using the KIGS-derived prediction model for children with idiopathic GHD. At near-adult height, ONH/SOD and controls had similar height, weight, and BMI SDS.</p> <p>Conclusions</p> <p>Compared to children with CGHD without midline defects, those with ONH/SOD presented with greater height, weight, and BMI SDS. These differences persisted at 1 year of GH therapy, but appeared to be overcome by long-term GH treatment.</p

Financing Higher Education in Sub-Saharan Africa: A Proposed Model Based on the Experiences of Ugandan Higher Education Institutions and Exemplary Practices from the Asian Tigers

Financing higher education has become one of the most contentious educational issues in both developed and third world countries. Among the causes highlighted by researchers are changing fiscal policies and government resource allocation priorities, coupled with rapid increases in college-going populations. Today, there is an upsurge in the numbers of colleges and enrollments all over the world. This upsurge and the forces of globalization, which put demands on institutions in terms of international rankings and the need to adopt the latest technologies, are putting enormous fiscal pressure on higher education institutions and their funders. Increasing enrollments without sufficient funding lead to substandard facilities and a decline in academic standards. To close that funding gap, institutions have resorted to privatization, which includes (inter alia) tuition charges and other fees. This has effectively turned the traditional model of higher education upside down. The challenge is: How do universities ensure they admit only the most qualified students and provide them with the best instruction, using state-of-the-art facilities, in a learning system run by highly qualified and motivated faculty staff? Against that background, this chapter analyzes best practices for financing higher education in developing countries that have vibrant higher education sectors (such as Malaysia), together with the challenges, practices, and experiences of funding Ugandan higher education institutions. The chapter ultimately suggests a suitable framework for higher education financing in Uganda and similar sub-Saharan African countries
