Wound Complications Following Laparoscopic Surgery in a Nigerian Hospital

Background: Different complications may occur at laparoscopic port sites. The incidence of these varies with the size of the ports and the types of procedure performed through them. Objectives: The aim was to observe the rate and types of complications attending laparoscopic port wounds and to identify risk factors for their occurrence. Patients and Methods: This is a prospective descriptive study of all patients who had laparoscopic operations in one general surgery unit of a University Teaching Hospital in Nigeria between January 2009 and December 2012. Results: A total of 236 (155 female and 81 male) patients were included. The laparoscopic procedures include 63 cholecystectomies, 49 appendectomies, 62 diagnostic, biopsy and staging procedures, 22 adhesiolyses, six colonic surgeries, eight hernia repairs and 22 others. Port site complications occurred in 18 (2.8%) ports on 16 (6.8%) patients including port site infections in 12 (5.1%) and hypertrophic scars in 4 (1.7%) patients, while one patient each had port site bleeding and port site metastasis. Nine of 11 infections were superficial, while eight involved the umbilical port wound. Conclusion: Port site complications are few following laparoscopic surgeries in our setting. We advocate increased adoption of laparoscopic surgeries in Nigeria to reduce wound complications that commonly follow conventional open surgeries.Keywords: Laparoscopy, Nigeria, wound complication

"Why not bathe the baby today?": A qualitative study of thermal care beliefs and practices in four African sites

BACKGROUND: Recommendations for care in the first week of a newborn's life include thermal care practices such as drying and wrapping, skin to skin contact, immediate breastfeeding and delayed bathing. This paper examines beliefs and practices related to neonatal thermal care in three African countries. METHODS: Data were collected in the same way in each site and included 16-20 narrative interviews with recent mothers, eight observations of neonatal bathing, and in-depth interviews with 12-16 mothers, 9-12 grandmothers, eight health workers and 0-12 birth attendants in each site. RESULTS: We found similarities across sites in relation to understanding the importance of warmth, a lack of opportunities for skin to skin care, beliefs about the importance of several baths per day and beliefs that the Vernix caseosa was related to poor maternal behaviours. There was variation between sites in beliefs and practices around wrapping and drying after delivery, and the timing of the first bath with recent behavior change in some sites. There was near universal early bathing of babies in both Nigerian sites. This was linked to a deep-rooted belief about body odour. When asked about keeping the baby warm, respondents across the sites rarely mentioned recommended thermal care practices, suggesting that these are not perceived as salient. CONCLUSION: More effort is needed to promote appropriate thermal care practices both in facilities and at home. Programmers should be aware that changing deep rooted practices, such as early bathing in Nigeria, may take time and should utilize the current beliefs in the importance of neonatal warmth to facilitate behaviour change

Current Neonatal Skin Care Practices in Four African Sites

Data for this study on skin care practices and emollient use in four African sites were collected using in-depth interviews, focus-group discussions and observations. Respondents were mothers, grandmothers, fathers, health workers, birth attendants and people selling skin-care products. Analysis included content and framework analyses.Emollient use was a normative practice in all sites, with frequent application from an early age in most sites. There were variations in the type of emollients used, but reasons for use were similar and included improving the skin, keeping the baby warm, softening/strengthening the joints/bones, shaping the baby, ensuring flexibility and encouraging growth and weight gain. Factors that influenced emollient choice varied and included social pressure, cost, availability and deep-rooted traditional norms. Massage associated with application was strong and potentially damaging to the skin in some sites.Given the widespread use of emollients, the repeated exposure of newborns in the first month of life and the potential impact of emollients on mortality, trials such as those that have been conducted in Asia are needed in a range of African settings

Bacterial isolates from blood cultures of children with suspected septicaemia in Calabar, Nigeria

BACKGROUND: Septicaemia is a common cause of morbidity and mortality among children in the developing world. This pattern has changed little in the past decade. Physical signs and symptoms, though useful in identifying possible cases have limited specificity. Definitive diagnosis is by bacteriologic culture of blood samples to identify organisms and establish antibiotic susceptibility. These results are usually not available promptly. Therefore a knowledge of epidemiologic and antimicribial susceptibility pattern of common pathogens is useful for prompt treatment of patients. This report highlights the pattern of bacterial isolates in our environment from a retrospective study of our patients' records. METHODS: One thousand, two hundred and one blood samples were analysed from children aged 0–15 years, admitted into the children's wards of the University of Calabar Teaching Hospital, Calabar, Nigeria with features suggesting septicaemia. Samples were collected under aseptic conditions and cultured for aerobic and anaerobic organisms. Isolates were identified using bacteriologic and biochemical methods and antibiotic sensitivity determined by agar diffusion method using standard antibiotic discs. RESULTS: Bacteria was isolated in 552 (48.9%) of samples with highest rates among newborns (271 : 50.8). The most frequent isolates were Staphylococcal aureus (48.7%) and Coliforms (23.4%). Results showed high susceptibilities to the Cephalosporins (Ceftriazone- 100%:83.2%, Cefuroxime-100%:76.5%) and Macrolides (Azithromycin-100%:92.9%) for S. aureus and coliforms respectively. This study underscores the importance of septicaemia as a common cause of febrile illness in children and provides information on common prevalent aetiologic agents and drug susceptibilities of the commonest pathogens. CONCLUSION: Staphylococcus aureus and coliforms were the leading causes of septicaemia in children in this locality, and the third generation cephalosporins and azithromycin were shown to be effective against these pathogens

Hormonal contraception, sexual behaviour and HIV prevalence among women in Cameroon

<p>Abstract</p> <p>Background</p> <p>Data on the effect of contraceptive methods, other than the condom, on HIV acquisition is not clear. The aim of this study was to describe hormonal contraceptive use, sexual behaviour and HIV prevalence among women in Cameroon in order to provide baseline information for future analytical studies.</p> <p>Methods</p> <p>This is a cross-sectional descriptive study based a nationally representative sample of 4486 sexually active women aged 15–49 years who participated in the 2004 Cameroon Demographic and Health Survey.</p> <p>Results</p> <p>The overall HIV prevalence was 7.4% (332/4486). The HIV prevalence was higher in the 25–35 year age group (10.03%), urban residents (9.39%), and formerly married (18.48%), compared to their compatriots. The prevalence was lower in women with five or more living child (3.67%), women in the low wealth index category (3.79%) and women who had no formal education (3.37%). The HIV prevalence was higher among women who had two or more partners in the last 12 months (10.26%) and women who reported to have had four or more partners in their lifetime (12.40%). The prevalence of HIV was higher among current hormonal contraceptive users (6.63%) compared to the current non-users (3.06%), among ever users of hormonal contraception (13.27%) compared to the never users (7.11%).</p> <p>Conclusion</p> <p>We conclude that the prevalence of HIV among sexually active women in Cameroon varies according to sociodemographic characteristics, sexual behaviour and hormonal contraceptive use. Our findings underscore the need to counsel women using hormonal contraception to be aware that hormonal methods do not protect against HIV infection. Given the biologic plausibility of the link between hormonal contraception and HIV infection, future research should focus on carefully designed prospective studies to establish the temporal relationship and estimate the incidence of HIV infection among women using and not using hormonal contraceptive methods.</p

Antenatal corticosteroids for women at risk of imminent preterm birth in low-resource countries: the case for equipoise and the need for efficacy trials

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials-the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial-have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns. In this article, we briefly present an appraisal of the current evidence around ACS, how these findings informed WHO's current recommendations on ACS use, and the knowledge gaps that have emerged in the light of new trial evidence. Critical considerations in the generalisability of the available evidence demonstrate that a true state of clinical equipoise exists for this treatment option in low-resource settings. An expert group convened by WHO concluded that there is a clear need for more efficacy trials of ACS in these settings to inform clinical practice

Evaluation studies on the efficacy of pyrethrum based insecticide (Tyrax®) in the control of mange in goats

Two studies were conducted in assessing the efficacy of a pyrethrnm based insecticide (Tyrax®) as a control for mange in West African Dwarf (WAD) goats. In the first study, an on-station trial, four goats infested with mange at the neck, sternum and scrotum were treated with tyrax solution (1:20 dilution) by surface application at 3 day interval for four weeks. Mange bad completely disappeared in two of the four goats while the efficacy was 70% in the others at 4 weeks of treatment. In the second study, an on-farm trial, 41 goats in 17 households were treated with tyrax (1:20 and 1:40 dilution rates) and ivermectin (ivomec), injected subcuteneously (1 ml/50kg body weight). Infested areas of goats included various parts of the body and the entire body. Observations were made at two periods after treatments (2 and 4 weeks). The efficacy was very high for all the treatments at 2 weeks but this was apparent at 4 weeks (P&lt;0.05). Significant difference (P&lt;0.05) was noticed only with ivomec® treatment between the two periods. Based on this work, tyrax® can be used in the treatment of localized mange infestation.Keywords: Efficacy, Goats, Mange, Prethru

Survey of teaching, research and conference experiences of paediatric surgical trainees in Nigeria

Aim: To determine the teaching methods used by residents in paediatric surgery in Nigeria and their exposure to research and conferences. Materials and Methods: A structured questionnaire was administeredto trainees in paediatric surgery in Nigeria seeking information regarding different teaching methods used, frequency of use, involvement in research and participation in conferences.Results: There were 11 respondents (91.6%) of 12 questionnaires that were distributed. All of them were training in accredited teaching hospitals in Nigeria. All of them had been involved in teaching medical students. Ten residents were involved in teaching in wards/bedside two timesor more in a week and all were involved in teaching at the clinics. Only one resident used audiovisual aid at least once a week to teach students. Eight trainees used tutorial or seminar group discussion as a teachingtool once a week. Four trainees had not used written essay as a way of teaching students while five had never given students lectures in a classroom before. All the respondents had participated in retrospectiveresearch while nine had been involved in prospective research. Nine residents had attended conferences nationally while two had attended international conferences. Six trainees presented a paper or moreat national conferences while one presented at an international conference. Conclusion: Trainees in paediatric surgery in Nigeria are significantly involved in the teaching of undergraduate medical students and clinical research. This should be encouraged and further enhanced by motivating the trainees to attend international conferences
