Background: Snakebite is a major public health problem among impoverished rural populations causing considerable morbidity and mortality in West Africa. Despite the huge burden of snakebite in this region, psycho-social impairment following snakebite has not been evaluated. In this study, we assessed for features of posttraumatic stress disorder and psycho-social impairment among rural snakebite victims in Northeastern Nigeria. Methods: Individuals with previous snakebite managed in our facility, defined as exposed to snakebite, and their matched relatives not exposed to snakebite were invited to participate in the study following community mobilization. A retrospective cohort study was conducted evaluating the presence of psycho-social functioning, posttraumatic stress disorder, quality of life, social disability, cognitive impairment, and psychological morbidity using standard tools administered by the investigators, trained nurses, and community health workers. Results: The prevalence of features of posttraumatic stress disorder among those exposed to snakebite compared to those not exposed to snakebite was 43% and 28%, respectively (risk ratio = 1.53; 95% confidence interval: 1.04–2.24; p = 0.024). Subjects exposed to snakebite had significantly poorer quality of life score in the psychological and social domains (p < 0.05). Other psycho-social complications associated with snakebite were impaired family/school functioning and psychological morbidity. No difference in cognitive functioning was observed between the two groups. Conclusions: Snakebite is complicated by features of posttraumatic stress disorder, poor quality of life, and psycho-social impairments in northeastern Nigeria. Detection, monitoring, and appropriate management interventions should be provided and made more accessible to snakebite victims to ameliorate mental and psychological impairment.

Despite the high prevalence of Helicobacter pylori infection in Nigeria, in the North-West there are no studies on the antibiotic sensitivity pattern of this organism. This study aims to determine the antibiotic sensitivity pattern of this bacterium as well as bridge the gap in knowledge. The study was cross-sectional in design. Questionnaires were administered in dyspeptic patients to obtain the relevant data. Two sets of gastric biopsy specimens were taken during upper gastrointestinal (GI) endoscopy. One set was sent to the histopathology laboratory for assessment and H. pylori identification, while the other set for culture was minced and plated on Columbia blood agar media (Oxoid Ltd, England) incubated at 37°C in an anaerobic jar containing CampyGen (Oxoid Ltd) to provide the required micro-aerobic environment. The disc diffusion method was used in determining the sensitivity pattern of isolates. Pre-treatment and post-treatment stool samples were collected from each patient for a H. pylori faecal antigen test to assess eradication rate. The sensitivity of H. pylori to amoxicillin was 9.2%, and 100% for both clarithromycin and levofloxacin. Tetracycline, metronidazole, cefuroxime, tinidazole and ciprofloxacin were 100% resitant. The prevalence of H. pylori at histology was 81.7%. Only 101 subjects had a positive H. pylori stool antigen test. This study showed a high amoxicillin resistance; however, there is high sensitivity (100%) to clarithromycin and levofloxacin. We recommended that levofloxacin be adopted in preference to amoxicillin as part of triple therapy in Nigeria. [ABSTRACT FROM AUTHOR]

Background: Snakebite though neglected, affects 5 million people yearly. More neglected is the psychological effect of envenomation. We determined prevalence and pattern of depression among patients admitted into snakebite wards of Kaltungo General Hospital Nigeria, and percentage recognized by clinicians. We also assessed for factors associated with depression. Methods: In a descriptive hospital based study, we used Patient Health questionnaire (PHQ-9) to make diagnosis of depression among the patients. We reviewed patients' clinical records to determine clinicians' recognition of depression. Results: Of 187 interviews analyzed, 47 (25%) had depression with none recognized by attending clinicians. Patients with snakebite complications (odd ratio [OR] 3.1, 95% CI 1.1-8.5), and previous history of snakebites (OR 2.7, 95% CI 1.1-6.1) were associated with mild depression. Worrying about family welfare (OR 31.5, 95% CI 6.5-152.9), financial loss (OR 14.6, 95% CI 1.8-121.5) and time loss (OR 14.6, 95% CI 1.8-121.5), past history of snakebites (OR 8.3, 95% CI 1.9-36.5) and lower income (Mean difference –25,069 [84 USD], 95% CI 35,509 [118 USD]-14,630 [49 USD]) were associated with severe depression. Conclusion: A quarter of in-patients of snakebite wards of the general hospital had comorbid depression that went unrecognized. Independent predictors of depression such as past history of snakebite, worrying about relations and having snakebite complications could help clinicians anticipate depression among patients. We recommend training of clinicians in the hospital on recognition of common psychological disorders like depression. [ABSTRACT FROM AUTHOR]

Background: This study was aimed at describing the profile of bacterial aetiology of secondary pneumonia in pulmonary tuberculosis (PTB) patients. Methods: A 22-month analysis of patients with PTB and secondary bacterial pneumonia was conducted. Data on isolates recovered and the antimicrobial susceptibility profile were recorded. Results: Of the 141 patients, there were 79 (56%) males and the mean age was 35.98±15.93. Gram-negative bacilli were isolated with equal frequency as Streptococcus pneumoniae (63 [44.7%]). Most of the isolates tested were sensitive to levofloxacin, ceftriaxone or chloramphenicol. Conclusion: Gram-negative bacilli are a major cause of pneumonia in patients with PTB on treatment.

HIV-associated Neurocognitive Disorders (HAND) are common among HIV-positive individuals. This study explored the prevalence and correlates of HAND in Nigeria. 80 HIV-positive and 40 HIV-negative adults selected from Aminu Kano Teaching Hospital (AKTH) received comprehensive evaluations. A multidomain neuropsychological test (MDNPT) battery assessing 7 domains was administered to the participants and their performance was combined with measures of functional status to classify impairments into various grades of HAND. Univariate and multivariate analyses were performed to identify correlates of symptomatic HAND. Among the HIV-positive individuals, 50% were highly active antiretroviral therapy-experienced (HAART+) and 50% were highly active antiretroviral therapy naive (HAART−). Symptomatic HAND was found among 40% of the HAART− individuals and 30% of the HAART+ individuals. Respective prevalence of HIV-associated dementia (HAD) was 23% and 5%, respectively (p=0.0002). In a binary logistic regression model, only fewer years of education independently predicted symptomatic HAND [Odds Ratio (OR) = 1.2, 95% confidence interval (CI) = 1.04–1.44, p=0.016]. The prevalence of HAND in Nigeria is high with HAD being commoner among HAART− patients. Provision of HAART and strict monitoring of patients at risk of HAND are needed to scale down the burden of the disease. [ABSTRACT FROM AUTHOR]
