Objective To investigate Schistosoma haematobium morbidity in infected pre‐school age children and establish their disease burden. Methodology Pre‐school age children (1–5 years) who were lifelong residents of the study area and had no other infections were included in the study. Participants underwent a physical examination with clinicians blinded to their infection status. Diagnosis of S. haematobium was by urine filtration. Results The prevalence of S. haematobium was 35.1% (146/416). The clinical features observed in patients with Schistosoma haematobium were as follows: wheezes (morbidity attributable factor (AF = 93.9%), haematuria (AF = 92.6%), ascites (AF = 91.5%), atopy (AF = 76.9%), inguinal lymphadenopathy (AF = 68.4%), stunting (AF = 38.2), malnutrition (MUAC)(AF = 20%) and weight for height scales (AF = 5%). Schistosoma. haematobium infected children were at greater odds ratio of presenting with inguinal lymphadenopathy (AOR)=99.2(95% CI 24.2 to 854.5), wheezes in the chest (AOR = 35.4 95% CI 15.3 to 94.2), Distended abdomen with ascites (AOR = 23.9 95% CI 11.4 to 54), haematuria (AOR = 12.6 95% CI 11.6 to 14.1), atopy history (AOR = 5.6 95% CI 1.85 to 20.2), malnutrition (AOR = 2.3 95% CI 1.4 to 3.2) and stunting (AOR = 1.9 95% CI 1.1 to2.7). Conclusion The study is novel as it demonstrates for the first time clinical morbidity markers associated with S. haematobium infection in pre‐school age children. Furthermore the study adds scientific evidence to the call for inclusion of pre‐school age children in schistosomiasis control programmes. These morbidity markers highlight the need for early diagnosis and screening for S. haematobium in pre‐school age children.
Introduction: Africa has many untreated neurosurgical cases due to limited access to safe, affordable, and timely care. In this study, we surveyed young African neurosurgeons and trainees to identify challenges to training and practice.Methods: African trainees and residents were surveyed online by the Young Neurosurgeons Forum from April 25th to November 30th, 2018. The survey link was distributed via social media platforms and through professional society mailing lists. Univariate and bivariate data analyses were run and a P-value < 0.05 was considered to be statistically significant.Results: 112 respondents from 20 countries participated in this study. 98 (87.5%) were male, 63 (56.3%) were from sub-Saharan Africa, and 52 (46.4%) were residents. 39 (34.8%) had regular journal club sessions at their hospital, 100 (89.3%) did not have access to cadaver dissection labs, and 62 (55.4%) had never attended a WFNS-endorsed conference. 67.0% of respondents reported limited research opportunities and 58.9% reported limited education opportunities. Lack of mentorship (P = 0.023, Phi = 0.26), lack of access to journals (P = 0.002, Phi = 0.332), and limited access to conferences (P = 0.019, Phi = 0.369) were associated with the country income category.Conclusion: This survey identified barriers to education, research, and practice among African trainees and young neurosurgeons. The findings of this study should inform future initiatives aimed at reducing the barriers faced by this group.
BackgroundLow-and middle-income countries (LMICs) are disproportionately affected by neurosurgical burden of disease. This health inequity causes constraints in decision-making. Neurosurgical ethics helps us to assess the moral acceptability and effectiveness of clinical decisions. We aimed to assess ethical neurosurgical care and its effect on patient satisfaction in Cameroon.MethodsTwo questionnaires hosted on Google Forms were administered among inpatients and staff at two Cameroonian neurosurgery centers. The questionnaires covered the factors influencing health outcomes and ethics. Data were collected from November 11, 2020, to March 11, 2021 and analyzed with SPSS v 26 to generate non-parametric tests with a threshold of significance at 0.05.ResultsSeventy patients and twenty healthcare providers responded to the survey. Most patients faced financial hardship (57.1%; 95% CI = 45.7–68.6%), and felt that this affected the care they received (P = 0.02). Patients noticed changes in the care plan and care delivery attributable to the neurosurgical units' lack of resources. According to the patients and caregivers, these changes happened 31.0–50.0% of the time (42.9%, 95% CI = 5.7–21.4%). The majority of patients were pleased with their involvement in the decision-making process (58.6%; 95% CI = 47.1–70.0%) and felt their autonomy was respected (87.1%; 95% CI = 78.6–94.3%).ConclusionMultiple challenges to neurosurgical ethical care were seen in our study. Multimodal interventions based on the four ethical principles discussed are necessary to improve ethical neurosurgical decision-making in this low resource setting.
Introduction Prompt diagnosis of acute schistosomiasis benefits the individual and provides opportunities for early public health intervention. In endemic areas schistosomiasis is usually contracted during the first 5 years of life, thus it is critical to look at how the infection manifests in this age group. The aim of this study was to describe the prodromal signs and symptoms of early schistosomiasis infection, correlate these with early disease progression and risk score to develop an easy to use clinical algorithm to identify early Schistosoma haematobium infection cases in resource limited settings. Methodology Two hundred and four, preschool age children who were lifelong residence of a schistosomiasis endemic district and at high risk of acquiring schistosomiasis were followed up from July 2019 to December 2019, during high transmission season. The children received interval and standard full clinical evaluations and laboratory investigations for schistosomiasis by clinicians blinded from their schistosomiasis infection status. Diagnosis of S. haematobium was by urine filtration collected over three consecutive days. Signs and symptoms of schistosomiasis at first examination visit were compared to follow-up visits. Signs and symptoms common on the last schistosomiasis negative visit (before a subsequent positive) were assigned as early schistosomiasis infection (ESI), after possible alternative causes were ruled out. Logistic regression identified clinical predictors. A model based score was assigned to each predictor to create a risk for every child. An algorithm was created based on the predictor risk scores and validated on a separate cohort of 537 preschool age children. Results Twenty-one percent (42) of the participants were negative for S. haematobium infection at baseline but turned positive at follow-up. The ESI participants at the preceding S. haematobium negative visit had the following prodromal signs and symptoms in comparison to non-ESI participants; pruritic rash adjusted odds ratio (AOR) = 21.52 (95% CI 6.38–72.66), fever AOR = 82 (95% CI 10.98–612), abdominal pain AOR = 2.6 (95% CI 1.25–5.43), pallor AOR = 4 (95% CI 1.44–11.12) and a history of facial/body swelling within the previous month AOR = 7.31 (95% CI 3.49–15.33). Furthermore 16% of the ESI group had mild normocytic anaemia, whilst 2% had moderate normocytic anaemia. A risk score model was created using a rounded integer from the relative risks ratios. The diagnostic algorithm created had a sensitivity of 81% and a specificity of 96.9%, Positive predictive value = 87.2% and NPV was 95.2%. The area under the curve for the algorithm was 0.93 (0.90–0.97) in comparison with the urine dipstick AUC = 0.58 (0.48–0.69). There was a similar appearance in the validation cohort as in the derivative cohort. Conclusion This study demonstrates for the first time prodromal signs and symptoms associated with early S. haematobium infection in pre-school age children. These prodromal signs and symptoms pave way for early intervention and management, thus decreasing the harm of late diagnosis. Our algorithm has the potential to assist in risk-stratifying pre-school age children for early S. haematobium infection. Independent validation of the algorithm on another cohort is needed to assess the utility further.
Background Schistosomiasis is known to affect the cognitive functions of children, however, but there is paucity of information on its impact on early childhood development in developing countries where the disease is endemic. This study aimed at determining the effects of schistosomiasis due to Schistosoma haematobium on early childhood development in children below 5 years old from Murewa District, Zimbabwe, including the benefits of treatment. Methods Preschool age children (PSAC) under the age of 5 years were screened at baseline and at 6 months post-treatment for S. haematobium infections diagnosed using the urine filtration method. Cognitive domains were assessed using the Griffith Mental Developmental Scales III on 136 PSAC. Multivariate logistic regression was used to determine the level of association between S. haematobium infection and performance in the cognitive domains adjusting for confounding factors (i.e. nutrition, hemoglobin levels, gender and age). Median Development Quotient scores of each cognitive domain at baseline and at 6 months post-treatment were compared and quantified. Results After adjusting for confounding factors, PSAC infected with S. haematobium had greater odds of having lower scores in the Foundation of Learning Domain (OR = 3.9, p = 0.008), Language and Communication Domain (OR = 3.2, p = 0.017), Eye-Hand Coordination Domains (OR = 10.7, p = 0.001), Personal-Social-Emotional Domain (19.3, p = 0.001) and in the Overall General Development Domain (7.2, p = 0.011). Improvement of cognitive performance was observed at 6 months post treatment in the following Domains; Language and Communication Domain (p = 0.003), Eye-Hand Coordination Domain (p = 0.02) and General Development Domain (p = 0.006). Conclusion The study showed that S. haematobium infection in PSAC is associated with lower cognitive scores in the Foundation of Learning, Language and Communication, Eye-Hand Coordination, Personal-Social-Emotional and in the Overall General Development domains. Our results strengthen the call for inclusion of PSAC in routine deworming programs for the control of urinary schistosomiasis and the need to develop locally validated tools to monitor early child development in endemic areas where resources are limited.
Background:Chronic subdural hematomas (CSDHs) usually occur in elderly patients following minor head trauma. Their occurrence is usually linked to cerebral atrophy secondary to alcohol, old age, or human immunodeficiency virus (HIV) infection. Spontaneous CSDHs have also been documented but are rare. They are usually caused by coagulopathies and various pathologies resulting in intracranial hypotension.Cases:We have observed a number of spontaneous CSDHs in HIV patients with normal platelet counts and no appreciable cerebral atrophy possibly caused by platelet dysfunction, hence we report about two such cases. To the best of our knowledge, no such cases have been reported in literature before.Conclusion:It is important to include CSDHs in the differential diagnosis of HIV patients presenting with neurological deficits even without a history of trauma.
Background:Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is associated with an increased prevalence of some malignancies. However, some observational studies have revealed an ever-decreasing prevalence of HIV in glioma patients. The relationship between HIV and brain gliomas has not been well established.Methods:A cross-sectional study was carried out in sub-Sahara Africa, a high HIV prevalence setting, to determine the prevalence of HIV among all glioma patients over a 2-year period.Results:A markedly reduced prevalence of HIV was found in glioma patients (8.3%) in comparison to the general population (14.3%). The presumably “antiglioma effect” of HIV and/or its treatment resulted in a 42% decrease in glioma occurrence in HIV positive patients compared to HIV negative individuals. Age and sex-adjusted prevalence were also lower among glioma patients with the protective effect observed more in younger patients and female sex.Conclusion:Our results corroborate the protective effect of HIV positivity vis-à -vis gliomas. This “antiglioma effect” could be attributed to either the HIV, its treatment, or both. Future studies focused on this “effect” may help unveil better preventative and possible therapeutic avenues for gliomas.
