RESUMO

OBJECTIVE: Maggot debridement therapy (MDT) is an emerging procedure involving the application of sterile maggots of the Dipteran species (commonly Lucilia sericata) to effect debridement, disinfection and promote healing in wounds not responding to antimicrobial therapy. Data on MDT in sub-Saharan Africa (including Nigeria) are scarce. This study aimed to use medicinal grade maggots as a complementary method to debride hard-to-heal necrotic ulcers and thereby promote wound healing. METHOD: In this descriptive study, we reported on the first group of patients who had MDT at Aminu Kano Teaching Hospital (AKTH), a tertiary hospital in northern Nigeria. The first instar larvae of Lucilia sericata were applied using the confinement (free-range) maggot therapy dressing method under aseptic conditions. RESULTS: Diabetic foot ulcer (DFU) grade III-IV constituted more than half of the wounds (53.3%), followed by necrotising fasciitis (30%), and post-traumatic wound infection (10%). Others (6.7%, included pyomyositis, surgical site infection and post traumatic wound infection). The median surface area of the wounds was 56cm2. Of the 30 patients, half (50%) had two MDT cycles with a median time of four days. Of the wounds, 22 (73%) were completely debrided using maggots alone while eight (27%) achieved complete debridement together with surgical debridement. Wound culture pre-MDT yielded bacterial growth for all the patients and Staphylococcus aureus was the predominant isolate in 17 wounds (56.7%) while Pseudomonas aeruginosa and Streptococcus pyogenes were predominant in five wounds (16.7%) each. Only four (13.3%) wound cultures yielded bacterial growth after MDT, all Staphylococcus aureus. CONCLUSION: A good prognosis was achieved post-MDT for various wounds. MDT effectively debrides and significantly disinfects wounds involving different anatomical sites, thus enhancing wound healing and recovery. MDT is recommended in such wounds.

RESUMO

BACKGROUND: Hand hygiene (HH) is a proven low-cost means to curtail the problem of hospital-acquired infection (HAI). However, a low HH compliance rate of 17.1% was found among surgical health workers at Ahmadu Bello University Teaching Hospital (ABUTH) in Zaria, Nigeria. METHODS: This was an intervention study conducted utilizing mixed methods to investigate the effectiveness of the World Health Organization (WHO) multimodal strategy to improve the HH compliance rate of doctors at ABUTH Zaria. The study was conducted between June and August 2022 and included delivering a behavioural change HH workshop to doctors followed by data collection in the surgical wards that had received environmental modification through the provision of an alcohol-based hand rub (ABHR), HH posters and nurses for visual and/or verbal reminders. RESULTS: The cumulative HH compliance rate was 69% (n=1774) and was significantly different from the baseline HH compliance rate of 17.1% (confidence interval 45.5 to 57.7, p<0.001). Observed HH was highest in the ward with both visual and verbal reminders (78%) and lowest (59%) where neither visual nor verbal reminders were provided (n=444 per ward). All respondents reported motivation to perform HH with the presence of ABHR. CONCLUSIONS: The WHO multimodal strategy is good for enhancing HH among health workers in the context of low- and middle-income countries. More research is needed to understand how much of a reduction in HAI is directly associated with efficient HH by health workers.

RESUMO

Monkeypox is a viral zoonosis caused by the monkeypox virus, an enveloped, double-stranded DNA virus belonging to the Orthopoxvirus genus in the Poxviridae family. Monkeypox has become a disease of global public health significance. Pregnant women are unfortunately among the those at an increased risk for exposure to monkeypox because their immune system is altered during pregnancy. They may also be at risk for more severe disease or a worse outcome than others. During pregnancy or while breastfeeding when consideration is given for pre-exposure or postexposure vaccination, nonreplicating (Modivied Vaccinia Ankara - Bavarian Nordic) or minimally replicating (LC16, KM Biologics) vaccines are preferred. The ACAM2000 vaccine is contraindicated in pregnancy because it contains live virus particles that can cause fetal vaccinia and fetal death. There are no data to support the use of tecovirimat in pregnant women. However, no fetal adverse effects were noticed when tecovirimat was used in animal studies.

RESUMO

OBJECTIVES: There are currently no national guidelines regarding bladder cancer treatment and clinical care pathways in Nigeria. The aim of this scoping review was to identify any gaps in the knowledge of epidemiology, clinical care and translational research in order to aid the development of a defined clinical care pathway and guide future research. METHODS: A scoping review was conducted by searching Medline, Ovid Gateway, The Cochrane library and Open Grey literature using predefined search terms from date of inception to June 2020. Studies were included if they discussed the epidemiology or treatment pathway of bladder cancer. All data were charted and were analysed in a descriptive manner. A consultation phase was also conducted consisting of a multidisciplinary team of clinicians and bladder cancer survivors. RESULTS: A total of 19 studies were deemed suitable for inclusion. The themes included the epidemiology of bladder cancer (high prevalence of schistosomiasis), research surrounding the biology of the disease and translational research including potential biomarkers. The consultation phase highlighted some possible sociocultural and infrastructural issues relating to both the diagnosis and treatment of bladder cancer, with poor knowledge of bladder cancer and its symptoms within the general population identified as a key issue. CONCLUSION: Even though the factors surrounding the relationship between schistosomiasis and the histopathology of bladder cancer remain unclear, there is potential for screening for schistosomiasis in endemic regions of sub-Saharan Africa. Other key areas for future research include the dissemination of information to the general population surrounding bladder cancer and its symptoms to encourage prompt diagnosis.

RESUMO

BACKGROUND: In line with global standards and progress made in Prevention of Motherto- Child Transmission (PMTCT), an assessment of the outcome of Early Infant Diagnosis in northern Nigeria is necessary to evaluate progress towards zero Human immunodeficiency Virus (HIV) infection among children. OBJECTIVES: This study assessed the infection rate and risk factors for mother-to-child HIV transmission among HIV-exposed children in Kano, northwest Nigeria. METHODS: Using a retrospective cohort design, pregnant HIV-positive women and their exposed infants were recruited over a period of six years (2010 to 2016). Participants were enrolled during pregnancy or at delivery in the PMTCT clinic of a tertiary health facility in Kano, Nigeria. The main outcomes for the study were Early infant diagnosis positivity for HIV at 6 weeks and risk factors for positivity. RESULTS: Of the 1,514 infants studied, early infant diagnosis was positive for HIV among 13 infants (0.86%). Infants whose mothers did not have antiretroviral therapy (adjusted Prevalence Ratio aPR = 2.58, 95%CI (1.85- 3.57)), who had mixed feeding (aPR = 12.06, 95%CI (9.86- 14.70)), and those not on antiretroviral prophylaxis (aPR = 20.39, 95%CI (16.04- 25.71)) were more likely to be infected with HIV. HIV-exposed infants on nevirapine and zidovudine prophylaxis were 95% and 74%, respectively, less likely to be infected with HIV. CONCLUSION: HIV infection rate remains high among HIV-exposed infants whose mothers did not receive PMTCT services. Scaling up proven interventions of early commencement of antiretroviral treatment for mothers, adherence to antiretroviral prophylaxis, and avoidance of mixed feeding among HIV-exposed infants would protect future generations from HIV infection.

RESUMO

Background: Hospital-acquired infections (HAIs) are an important cause of morbidity and mortality. This study examined the epidemiology, clinical outcomes and microbiological profile of HAIs. Methods: This prospective study was carried out on patients identified to have developed HAIs while admitted to the medical wards, surgical wards, dialysis unit and intensive care unit (ICU) of the hospital. Patients were recruited consecutively until the target study population was reached. A clinical evaluation and relevant laboratory investigations were carried out. Results: A total of 100 patients who had 144 episodes of HAIs were studied. Rates of HAIs were 7.16%, 18.63% and 1.75% in the medical wards, ICU and surgical wards, respectively. The most common HAI was urinary tract infection caused by Escherichia coli. High-level resistance to commonly prescribed antibiotics, especially ampicillin and ceftriaxone, was observed among causative bacteria. Conclusion: The burden of HAIs is high and similar to other parts of Nigeria. There is a need for continued surveillance of HAIs in all the wards of the hospital in order to fully describe the extent of the problem.

RESUMO

OBJECTIVE: Hospital-acquired infections (HAI) are a global problem and a major public health concern in hospitals throughout the world. Quantification of HAI is needed in developing countries; hence we describe the results of a 2-year surveillance data in a tertiary hospital in Nigeria. METHODOLOGY: This study is a 2-year review using secondary data collected at a tertiary referral center in northwestern Nigeria. The data was collected using surveillance forms modeled based on the Centre for Disease Control (CDC) protocol. Descriptive statistics were used to present results as frequencies and percentages. RESULT: 518 patients developed HAI out of 8216 patients giving an overall prevalence of 6.3%. The mean age of the patients was 35.98 years (±15.92). Males constituted 281 (54.2%). UTI 223 (43.1%) was the most prevalent HAI. Overall, E. coli 207 (40.0%) was the most frequent isolates followed by P. aerugenosa 80 (15.4%). There was a high prevalence of cloxacillin resistant S. aureus (67.9%) and gram-negative rods resistant to third-generation cephalosporins. Trimethoprim-sulfamethoxazole resistance across the board was more than 90%. CONCLUSION: There is a high burden of HAI especially UTI in our hospital with resistance to commonly used antibiotics documented.
