Role of the IL8 rs4073 polymorphism in central nervous system toxicity in patients receiving multidrug-resistant tuberculosis treatment / Papel do polimorfismo rs4073 do gene IL8 na toxicidade do sistema nervoso central em pacientes em tratamento para tuberculose multirresistente

ABSTRACT Objective: To determine the role of the IL8 rs4073 polymorphism in predicting the risk of central nervous system (CNS) toxicity in patients receiving standard pharmacological treatment for multidrug-resistant tuberculosis (MDR-TB). Methods: A cohort of 85 consenting MDR-TB patients receiving treatment with second-line antituberculosis drugs had their blood samples amplified for the IL8 (rs4073) gene and genotyped. All patients were clinically screened for evidence of treatment toxicity and categorized accordingly. Crude and adjusted associations were assessed. Results: The chief complaints fell into the following categories: CNS toxicity; gastrointestinal toxicity; skin toxicity; and eye and ear toxicities. Symptoms of gastrointestinal toxicity were reported by 59% of the patients, and symptoms of CNS toxicity were reported by 42.7%. With regard to the genotypes of IL8 (rs4073), the following were identified: AA, in 64 of the study participants; AT, in 7; and TT, in 11. A significant association was found between the dominant model of inheritance and CNS toxicity for the crude model (p = 0.024; OR = 3.57; 95% CI, 1.18-10.76) and the adjusted model (p = 0.031; OR = 3.92; 95% CI, 1.13-13.58). The AT+TT genotype of IL8 (rs4073) showed a 3.92 times increased risk of CNS toxicity when compared with the AA genotype. Conclusions: The AT+TT genotype has a tendency to be associated with an increased risk of adverse clinical features during MDR-TB treatment.

RESUMO Objetivo: Determinar o papel do polimorfismo rs4073 do gene IL8 na previsão do risco de toxicidade do sistema nervoso central (SNC) em pacientes em tratamento farmacológico padrão para tuberculose multirresistente (TBMR). Métodos: Amostras de sangue de uma coorte de 85 pacientes com TBMR que assinaram um termo de consentimento livre e esclarecido e que estavam recebendo tratamento com medicamentos antituberculosos de segunda linha foram amplificadas para o gene IL8 (rs4073) e genotipadas. Todos os pacientes foram avaliados clinicamente quanto a evidências de toxicidade do tratamento e categorizados de acordo com os achados. Foram avaliadas as associações brutas e ajustadas. Resultados: As principais queixas enquadraram-se nas seguintes categorias: toxicidade do SNC; toxicidade gastrointestinal; toxicidade cutânea; e toxicidade ocular e ototoxicidade. Sintomas de toxicidade gastrointestinal foram relatados por 59% dos pacientes, e sintomas de toxicidade do SNC foram relatados por 42,7%. Foram identificados os seguintes genótipos de IL8 (rs4073): AA, em 64 dos participantes; AT, em 7; TT, em 11. Houve associação significativa entre o modelo dominante de herança e toxicidade do SNC no modelo bruto (p = 0,024; OR = 3,57; IC95%: 1,18-10,76) e no ajustado (p = 0,031; OR = 3,92; IC95%: 1,13-13,58). O genótipo AT+TT do gene IL8 (rs4073) apresentou risco 3,92 vezes maior de toxicidade do SNC que o genótipo AA. Conclusões: O genótipo AT+TT tende a se associar a um maior risco de características clínicas adversas durante o tratamento da TBMR.

Outpatient prevention counseling for malaria in northwest Nigeria: A single-centre descriptive cross-sectional study

To assess the proportion of caregivers of children and patients who received malaria prevention counseling from their healthcare provider at the time of outpatient malaria treatment. Methods: This was a descriptive cross-sectional study involving 353 randomly selected adult patients and caregivers of children attending the general and paediatric outpatient clinics of a Nigerian hospital. An interviewer-administered questionnaire was used to collect data on participants' sociodemographics and last malaria-episode characteristics. Chi square test and logistic regression analysis were used to determine factors associated with and predictors of receiving malaria-prevention counseling, respectively. Results: The mean age of the respondents was (33.6±9.6) years; they were predominantly females (257, 72.8%). Most had at least secondary-level education (304, 86.1%); the family size was mostly 1-6 persons in 202 (57.2%) respondents. They were treated mostly by doctors 256 (72.5%), but only 132 (37.4%) received malaria prevention counseling. Educational-level (χ

Prevalence of hyperhomocysteinemia and hypovitaminosis B12 among acute ischemic stroke patients

Background: Deficiency of Vitamin B12 can lead to hyperhomocysteinemia. Hyperhomocysteinemia constitutes an abnormally high level of homocysteine in the serum, above the upper limit of normal for an environment. The two conditions are significant risk factors for the development of stroke. There is a paucity of data on the prevalence of these biochemical risk factors in stroke patients in our environment which brought about this study. Objective: The objective of the study was to determine how prevalent hyperhomocysteinemia and hypovitaminosis B12 are in acute ischemic stroke patients in Zaria. Materials and Mthods: This is a cross­sectional prospective study conducted from February 2014 to March 2015 in ABUTH Zaria. One hundred patients with clinical diagnosis of first­ever ischemic stroke confirmed by brain computed tomography scan, and another apparently healthy age­ and sex­matched one hundred controls were recruited. Their fasting serum homocysteine and Vitamin B12 were determined using the enzyme­linked immunosorbent assay technique. Prevalence of high homocysteine and low Vitamin B12 was determined.Results: Thirty­four percent (34%) of patients had high and 66% patients had normal serum homocysteine, whereas 81% of patients had low and 19% of patients had normal serum Vitamin B12, and the difference was found to be statistically significant (P < 0.05).There was significant negative correlation between serum homocysteine and Vitamin B12 among cases with P = 0.04 and r = −0.198.Conclusion: The Prevalence rates of hyperhomocysteinemia and hypovitaminosis B12 among ischemic stroke pateints were 34% and 81%, respectively

Hypoglycemia in a child with tramadol poisoning

Tramadol is a central acting analgesic of the opioid group used for moderate to severe pain. Tramadol overdose can be accidental or intentional and is more common in adolescent and adult males. We report the case of a 4-year-old boy presenting with hypoglycemia following tramadol poisoning with loss of consciousness and convulsion; he was managed conservatively and made remarkable improvement without any sequelae

Hand washing practices and techniques among health professionals in a tertiary hospital in Kano

Background: The simple act of hand washing has been proven to reduce the risk of acquiring hospital infection; especially with the current concern of Ebola viral disease. Hospital acquired infections have contributed significantly to overall mortality and morbidity and health care cost. They report that hand washing remains at an unacceptable low level in most medical environments; with large numbers of doctors and nurses routinely forgetting to wash their hands before touching patients. Transmission of health-care-associated infections often occurs via the contaminated hands of health care workers. Materials and Methods: It was a descriptive cross-sectional study carried out among randomly selected doctors and nurses in Aminu Kano Teaching Hospital; Kano. The questionnaires were administered to the respondents during their ward rounds or clinic sessions. Results: One hundred and forty health professionals comprising 98 nurses and 42 doctors were studied. About 64.4% of them were aware of the World Health Organization (WHO) global hand washing day but only 15% stated the date correctly. About 99.3% of them believed that if hand washing is done correctly it can reduce the risk of infection. All (100%) of the health professionals use water and soap or hand rubs as agents of hand washing. About 93.6% were taught hand washing technique and 47% were aware of the five moments in hand washing but only 17% of them could list the five moments in hand washing. Only 25.7% health professionals knew the correct steps of hand washing (?2 = 2.444; df = 2; P = 0.295). Ninety-one percent of the health professionals had seen posters on hand washing. Majority (72.1%) adhered to principles of hand washing (?2 = 0.015; df = 1; P = 0.902) while 82.1% wash their hands before touching patients (?2 = 2.841; df = 1; P = 0.092). However; most of them (95%) washed their hands after touching patients and 97% washed their hands after handling body fluids or secretions from patients. On the other hand; only 39% health professionals washed hands before wearing hand gloves (?2 = 0.321; df = 1; P = 0.571) but 95% washed hands after removing the hand gloves. Ninety-nine percent washed their hands after visiting or using the restroom. Conclusion: This study underscores the need for continuous information and education of health professionals on the importance WHO global hand washing day. As doctors and nurses are important in the health care team; it is important to provide the appropriate knowledge and training regarding preventive practices of infectious diseases. Training and retraining of health professionals on correct steps of hand washing will encourage and remind them on the importance of washing hands before wearing gloves and before touching patients to reduce the risk of infection and cross infection

Childhood pulmonary tuberculosis with digital clubbing

Tuberculosis is prevalent in the tropics and sub-tropics; late treatment may result in severe morbidity and mortality. Digital clubbing has been associated with several diseases including pulmonary tuberculosis though the exact mechanism is poorly understood; this has been linked mostly with severe adult pulmonary tuberculosis associated with cavitations, hypoalbuminemia and smear-positive sputum, but the case of an 11-year-old boy who presented with digital clubbing and leukonychia with absence of cavitary lesion or hypoalbuminemia is reported

Acute psychosis following diabetic ketoacidosis in an 11-year-old, management challenges in a resource-limited setting

Diabetes mellitus [DM] is the most common endocrine disorder in children and type 1 DM is the most common; however increasing incidence of type 2 DM is being reported, especially in western societies. Occurrence of psychiatric disorders has been associated with type 2 DM but is rare in those with type 1 DM; therefore the case of an 11-year-old girl who was treated for diabetic ketoacidosis, but suddenly developed acute psychotic symptoms shortly after regaining consciousness is reported. Atypical antipsychotic medications were avoided in this case for concerns of their risk of causing abnormal glucose metabolism

It was first described by Alfred Poland in 1840 and may occur with different gravity. Our patient is an eight‑year‑old Nigerian girl with left‑sided anterior chest wall defect with no detectable structural heart abnormality but presented with repeated episodes of syncopal attacks following minor trauma to the anterior chest wall.

Multiple nasal polyps in an 11 year old asthmatic child: a case report

Childhood asthma is a common chronic respiratory disease; it may be associated with other co-morbidities which may influence its severity. Among these is chronic rhino sinusitis, conjunctivitis, or gastroesophageal reflux disease. However, nasal polyps are rare in asthmatic children, being more common in those more than 20 years. Its exact cause is not completely understood and it has been associated with sensitivity to non-steroidal anti-inflammatory drugs. In this communication we report a case of a 11-year-old boy with multiple nasal polyps and difficult to manage asthma
