Serum zinc level in children with febrile convulsion and its comparison with that of control group

Febrile convulsion is the most common disorder in childhood with good prognosis. There are different hypotheses about neurotransmitters and trace element [such as zinc] changes in cerebrospinal fluid and serum, which can have a role in pathogenesis of febrile convulsion. The aim of the present prospective analytical case-control study was to determine whether there was any changes in serum zinc level in children with febrile convulsion during seizure. Ninety-two children aged 6 months to 5 years were divided into three groups: group A, 34 children with febrile convulsion, group B, 40 children having fever without convulsion, and group C, and 18 children with non-febrile convulsion. Serum zinc levels for the three groups were estimated by atomic absorption spectrophotometry [AAS]. Data were analyzed to compare zinc level among the three groups using appropriate statistical tools employing SPSS 13. Serum zinc levels of groups A, B, and C had a mean value of 76.82 +/- 24.36mg/1, 90.12 +/- 14.63 mg/1 and 94.53 +/- 17.39 mg/l, respectively. Serum zinc level of group A was lower than those of the other two groups [P < 0.006]. It was also lower in group B than in group C [P < 0.006]. These findings revealed that serum zinc level decreases during infection; this decrease was more significant in patients with febrile convulsion

Niveles de zinc en líquido prostático de pacientes con patologías de próstata / Zinc levels in prostatic fluid of patients with prostate pathologies

La próstata es una glándula que rodea la uretra posterior en el hombre, junto a las vesículas seminales, produce los líquidos prostático y seminal. La prostatitis, la hiperplasia benigna y el cáqncer de próstata son las patologías más frecuentes que la afectan. El zinc es un elemento importante en la composición química del líquido prostático y juega un papel fundamental en la inmunología de los fenómenos infecciosos y neoplásicos. El objetivo de la presente investigación fue determinar las concentraciones de zinc en líquido prostático de pacientes con patología de dicha glándula a fin de que sirva como parámetro para su diagnóstico y fundamento para una nueva forma terapéutica. Se estudiaron 30 pacientes con patología de próstata y 10 sujetos sanos, de quienes se obtuvo una muestra de líquido prostático mediante masaje prostático para luego determinar la concentración de zinc a través de espectrometría de absorción atómica con atomización electrónica (ETA-AAS). En los 11 pacientes con hiperplasia de próstata se encontró una concentración promedio de zinc de 15.087,78 µmol/dL, los 10 pacientes con prostatitis tuvieron una concentración de 863,33 µmol/dL y los 9 pacientes con diagnóstico de cáncer de próstata presentaron una concentración de zinc de 1.027,60 µmol/dL. La concentración promedio de zinc en el grupo control (10 personas) fue de 7.467,52 µmol/dL. En conclusión, la concentración baja de zinc en los pacientes con prostatitis y cáncer de próstata, con respecto al grupo control, permite plantear la posibilidad de utilizar suplementos de zinc como terapia complementaria en los pacientes con prostatitis, y la determinación de zinc, junto al antígeno prostático, representa un nuevo elemento para los casos en que exista dudas sobre el diagnóstico de cáncer de próstata y de hiperplasia prostática benigna.

Cytokines and zinc levels in serum and cerebrospinal fluid of children with febrile seizures and encephalitis

The present study was proposed in an attempt to understand the role of serum and cerebrospinal fluid [CSF] levels of proinflammatory cytokines [TNF-alpha, IL-1beta and IL-6] and zinc in children with febrile convulsions and cases with encephalitis in comparison with normal ranges. Fifty patients were enrolled in the study, 15 with febrile convulsions, 15 patients with acute encephalitis and a control group of 20 patients with febrile illness but no convulsions. Serum and CSF levels of TNF-alpha, IL1-Beta and IL-6 were significantly higher in cases with encephalitis than in cases with febrile convulsions and control. There were no significant differences between cases with febrile convulsions and controls. On comparing cases with febrile convulsions and cases with encephalitis, serum and CSF levels of pro-inflammatory cytokines were significantly higher in cases with encephalitis. It was also found that children with febrile convulsions had decreased serum and CSF levels of zinc much less than in both cases with encephalitis and control groups. The correlation between serum and CSF levels of pro-inflammatory cytokines was significantly positive for cases with febrile convulsions and encephalitis, while there was no correlation between serum and CSF zinc levels in both groups
