ABSTRACT
Objective: The aim of this study is to compare specific three-institution, cross-country data that are relevant to the Global Surgery indicators and the functioning of health systems. Methods: We retrospectively reviewed the clinical and socioeconomic characteristics of pediatric patients who underwent cerebrospinal fluid (CSF) diversion surgery for hydrocephalus in three different centers: the University of Tsukuba Hospital in Ibaraki, Japan (HIC), the Jose R. Reyes Memorial Medical Center in Manila, Philippines [low-to-middle-income country (LMIC)], and the Federal Neurosurgical Center in Novosibirsk, Russia (UMIC). The outcomes of interest were the timing of CSF diversion surgery and mortality. Statistical tests included descriptive statistics, Cox proportional hazards model, and logistic regression. Nation-level data were also obtained to provide the relevant socioeconomic contexts in discussing the results. Results: In total, 159 children were included, where 13 are from Japan, 99 are from the Philippines, and 47 are from the Russian Federation. The median time to surgery at the specific neurosurgical centers was 6 days in the Philippines and 1 day in both Japan and Russia. For the cohort from the Philippines, non-poor patients were more likely to receive CSF diversion surgery at an earlier time (HR = 4.74, 95% CI 2.34-9.61, p <0.001). In the same center, those with infantile or posthemorrhagic hydrocephalus (HR = 3.72, 95% CI 1.70-8.15, p = 0.001) were more likely to receive CSF diversion earlier compared to those with congenital hydrocephalus, and those with postinfectious (HR = 0.39, 95% CI 0.22-0.70, p = 0.002) or myelomeningocele-associated hydrocephalus (HR = 0.46, 95% CI 0.22-0.95, p = 0.037) were less likely to undergo surgery at an earlier time. For Russia, older patients were more likely to receive or require early CSF diversion (HR = 1.07, 95% CI 1.01-1.14, p = 0.035). External ventricular drain (EVD) insertion was found to be associated with mortality (cOR 14.45, 95% CI 1.28-162.97, p = 0.031). Conclusion: In this study, Filipino children underwent late time-interval of CSF diversion surgery and had mortality differences compared to their Japanese and Russian counterparts. These disparities may reflect on the functioning of the health systems of respective countries.
ABSTRACT
@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Pediculosis continues to be a common yet neglected public health problem especially in children. Trials to test for effectiveness for head lice interventions are heterogeneous, and a recent systematic review recommended the use of cluster randomization and centralized administration (e.g. school) of permethrin for pediculosis trials.</p> <p style="text-align: justify;"><strong>OBJECTIVE:</strong> To compare the effectiveness of a school-based to a home-based intervention using permethrin 1% shampoo in treating pediculosis capitis. </p> <p style="text-align: justify;"><strong>METHODS:</strong> We conducted a pragmatic, cluster-randomized trial at the Makati Elementary School. All Grade Four students (n = 211), belonging to a total of five class sections, were invited to participate in the study. Students with a known allergic reaction to permethrin 1% shampoo, with open wounds on the scalp, or were absent on Days 1 or 10 of the intervention period were excluded. The five class sections were randomized to receive permethrin 1% shampoo to be applied either in school, or at home. The students were classified as having none, light, medium, or heavy infestation prior to Day 1 and after Day 10 treatment. Prevalence, incidence, and treatment outcomes were measured.</p> <p style="text-align: justify;"><strong>RESULTS:</strong> The baseline prevalence of pediculosis capitis was 58.4%. General characteristics of students were similar between groups. No significant clustering in pediculosis classification was observed. The school-based group had the same prevalence in pediculosis at Days 1 and 10, had no incident cases, and were limited to light infestation by Day 10, but had no treatment success outcomes. The home-based group had increased prevalence by Day 10, poor compliance with Day 1 and 10 shampoo, incident cases, although it registered a higher treatment success rate.</p> <p style="text-align: justify;"><strong>CONCLUSION:</strong> Compared to standard home based intervention, a school-based strategy resulted in less incident cases (0% vs. 37%), reduction in pediculosis severity (p = 0.007), and higher compliance (100% vs. 58.3%). Control of pediculosis in this specific community is largely warranted because of its high prevalence rate of 59.7%.</p> <p style="text-align: justify;"> </p>
