ObjectiveWe assessed the impact of political conflict (Boko Haram) on tuberculosis (TB) case notifications in Adamawa State in North-east Nigeria.DesignA retrospective analysis of TB case notifications from TB registers (2010–2016) to describe changes in TB notification, sex and age ratios by the degree of conflict by local government area.SettingAdamawa State.Participants21 076 TB cases notified.Results21 076 cases (62% male) were notified between 2010 and 2016, of which 19 604 (93%) were new TB cases. Areas affected by conflict in 2014 and 2015 had decreased case notification while neighbouring areas reported increased case notifications. The male to female ratio of TB cases changed in areas in conflict with more female cases being notified. The young and elderly (1–14 and >65 years old) had low notifications in all areas, with a small increase in case notifications during the years of conflict.ConclusionTB case notifications decreased in conflict areas and increased in areas without conflict. More males were notified during peace times and more female cases were reported from areas in conflict. Young and elderly populations had decreased case notifications but experienced a slight increase during the conflict years. These changes are likely to reflect population displacement and a dissimilar effect of conflict on the accessibility of services. TB services in conflict areas deserve further study to identify resilient approaches that could reach affected populations.
Background Intraoperative bleeding during functional endoscopic sinus surgery (FESS) poses a challenge to both surgeon and anesthetist. The primary aim of this study was to evaluate the effectiveness of local, intravenous and combined use of tranexamic acid (TA) in improving the surgical field quality during FESS. Methods We conducted a randomized controlled double‐blinded prospective trial on 120 patients scheduled for elective FESS. After induction of general anesthesia, patients were randomly and evenly assigned to one of four groups; IV TA, local TA, both IV and local TA, and placebo. Surgical field was assessed using five‐point Boezaart scale. Total fentanyl and esmolol consumption, operative time, recovery time, and postoperative complications were recorded. Results Surgical field quality score was the best in IV and local TA group compared to others (p < 0.001). Mean operative time was found significantly shorter in IV and local TA group than placebo one. Total fentanyl consumption was significantly lower in IV and local TA group comparing to others (p = 0.025). Mean recovery time was significantly shorter for IV and local TA group compared to others. Total fentanyl consumption was significantly lower in IV and local TA group comparing to others. No significant differences were found of mean arterial pressure and heart rate decline in four groups. None of the patients in four groups required esmolol administration. No statistically significant differences were found in change of hemoglobin, hematocrit, prothrombin time, and partial thromboplastin time over time in all groups. Conclusion The combined use of topical and intravenous TA provided the best surgical field in FESS, less fentanyl consumption, and less recovery time without causing significant side effects.
SummaryBackgroundDegranulation of mast cells (MCs) releases several mediators such as vascular endothelial growth factor (VEGF), chymase, tryptase, histamine, and cytokines, which all have important roles in the severity of dengue infection. We aimed to investigate the role of MCs in severity of dengue.MethodsWe searched for relevant studies in 10 databases on 15 August 2016. Meta‐analysis (MA) was conducted by R version 3.5.0.ResultsWe included 24 studies. in vivo and in vitro studies showed higher MC products released from infected mice/cells with dengue virus. In addition, when administering MC stabilizers or antihistaminic drugs, there was a decrease in vascular/capillary permeability. In human and at early stages, studies revealed an insignificant difference in VEGF levels in dengue fever (DF) versus dengue hemorrhagic fever (DHF) (standardized mean difference [SMD] 0.145; 95% confidence interval [CI], −0.348‐0.638). Meanwhile, at acute stages and compared with healthy controls, high heterogeneity with an inconclusive difference in VEGF levels were noted in DF and DHF. However, pooled serum and plasma levels of VEGF were increased significantly in dengue shock syndrome (DSS) versus healthy controls (SMD 0.65; 95% CI, 0.3‐0.95). There were also significantly higher chymase levels in DHF patients compared with DF during the acute phase (MD −6.531; 95% CI, −12.2 to −0.9).ConclusionVEGF and chymase levels are mediators in dengue pathogenesis. However, limited data were available to support their role in severe dengue cases. Further studies are needed to evaluate the function of other mediators in dengue severity.
The Patient Protection and Affordable Care Act (PPACA) addresses consumer protection, employer-provided insurance coverage, as well as the government’s role in providing health care access to the most vulnerable populations. Within the practice of neurology, the PPACA has the challenging goal of reconciling the needs of the growing elderly population with the financial barriers to costly yet available health care services. To bridge that gap, all health care professionals working in the field of neurology must reflect on the effect previous Medicare reimbursement policies have had on the current practice of neurology, and utilize lessons learned in recent years. The test of time will tell whether the PPACA will achieve the goal of decreasing in health care spending while ensuring quality universal healthcare services.
