The extent of the problem differs among age groups, social-economic classes, and country to country. However, there is a dearth of information on the pattern of poisoning in adolescents in Nigeria. Objective: The study aims to assess the poisoning pattern among adolescent patients admitted into Tertiary Care Hospitals in Nigeria. Methods: In this study, a critical, constructive analysis of relevant literature on the subject areas of poisoning cases in tertiary care hospitals in Nigeria was carried out. Published cases between the periods of 2000 and 2019 were analysed. Results: The study showed that 24 patients made up of 13 females and 11 males were involved in poisoning cases during the studied period (2000–2019). About 85% of the patients were aged 10–15 years, while 12.5% were aged 16–30 years. Most of the poisoning cases (83%) occurred at home. Accidental cases were 29.16%, while 70.8% of the cases were intentional. Among the 17 intentional cases, 28.6% were ingested for the hallucinating effect and 17.6%) were suicidal cases. The agents used for poisoning included organophosphates, plant extracts, alcohol, drugs, food, kerosene and herbal mixture, among others. Some reasons for poisoning or suicidal intent observed in the study include peer influence, edgy relationships in the family system, disagreement with parents, failure in examination, and clashes with the boyfriend. Conclusion: There is a need for the government to establish poisoning control centres in each region of the country for proper profiling of the poisoning epidemic. Furthermore, parents and guardians are strongly advised to closely observe their teenage children and educate them about the dangers of any poisoning. Also, schools should provide friendly and accommodating environments to minimize and possibly eliminate suicidal intentions in youths and adolescents.

Age-related reduction in fertility is linked with decreased rate of fertility, increased risk of miscarriage, pregnancy complications, and birth defects. The impact of senescence on male fertility is attributed to the production of poor quality and quantity of spermatozoa that can lead to increased risk of abnormal pregnancy, induction of genetic defect in spermatozoa, and transmission of germ-line mutation to offspring. In recent times, women tend to delay childbearing because of education and career opportunities, and some believed they would achieve pregnancy irrespective of their age through assisted reproduction technology. In this chapter the effects of senescence, oxidative stress, and apoptosis on fertility would be discussed as factors that are interrelated in fertility. Published articles used for this review were obtained from PubMed and Google scholar using senescence, oxidative stress, apoptosis, and fertility as search phrase. Evidences suggest that senescence, apoptosis, and oxidative stress are associated with fertility in both males and females. Senescence may influence increase generation of oxidants, induce apoptosis, and can negatively impact on fertility. It is therefore suggested that couples should have their children early and those with fertility challenges should seek early medical attention, that is, within their reproductive age range. Also, adequate precaution would need to be adhered to when selecting germ cells for use in assisted reproduction procedures.

Resveratrol (RES) is a natural polyphenol with antioxidant and anti-inflammatory properties. This study was carried out to evaluate the protective role of RES in Fe and Cu sulphate-induced oxidative stress in Drosophila melanogaster. MethodsAdult wild type flies were fed Cu2+ and Fe2+ (1 mM each) and/or RES (30 and 60 mg/kg diet) for 7 days. Survival, negative geotaxis and emergence rate were evaluated by daily recording of fruit fly mortality and final analysis. Fruit flies were anaesthetized using CO2 gas, homogenized and centrifuged at 4,000 rpm for 10 minutes at 4 °C. Aliquots of the supernatants were used for the estimation of biochemical markers using spectrophotometry. ResultsFruit flies co-treated with FeSO4 + CuSO4 (1 mM each) + RES (30 and 60 mg/Kg) significantly elevated H2O2, NO, lipid ...

E-waste management practices in Nigeria have remained completely primitive until date; and e-waste workers have little or no occupational safety knowledge and devices. The thousands of chemicals in e-waste have been reported to be toxic to human health in any degree of exposure. The present study has assessed the risk of liver damage in workers occupationally exposed to e-waste in Benin City, South-south Nigeria in 2014. Serum activities of liver enzymes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyltransferase (GGT) and alkaline phosphatase (ALP)]; and levels albumin (ALB), total bilirubin (T/Bil) and conjugated bilirubin (C/Bil) were determined using standard colorimetric methods. Serum Alpha fetoprotein (AFP) was determined using ELISA in Nigerian e-was...

Benzene is a component of many petrochemicals and a ubiquitous environmental pollutant. Phenol is one of its principal metabolites and serves as a biomarker of exposure to benzene. The mechanism of its toxicity is incompletely elucidated. Benzene’s interaction with key micronutrients; copper (Cu), iron (Fe), and zinc (Zn) in the haemopoietic system has only been poorly explored, particularly in the developing countries where their status is variable and uncertain, with attendant intense exposure to petrochemicals. Material and Methods: Two groups of 50 gasoline dispensers (GDs) and 50 non-occupationally exposed participants were selected from Oye Local Government Area, Nigeria. The duration of occupational exposure was 2–10 years. Serum levels of Cu, Fe, and Zn were determined using flame atomic absorption spectrophotometry while heme and phenol were de...
