Exposure of Petrol Station Attendants and Auto Mechanics to Premium Motor Sprit Fumes in Calabar, Nigeria
A
population-based-cross-sectional survey was carried
out to investigate the potential risk of exposure to
premium motor spirit (PMS) fumes in Calabar,
Nigeria, among Automobile Mechanics (AM), Petrol
Station Attendants (PSA) and the general population.
Structured questionnaire was administered on the
randomly chosen subjects to elicit information on
their exposure to PMS. Duration of exposure was taken
as the length of work in their various occupations.
Venous blood was taken for methaemoglobin (MetHb) and
packed cells volume (PCV). Mean MetHb value was higher
in AM (7.3%) and PSA (5.8%) than in the
subjects from the general population (2.7%). PCV
was lower in PSA (30.8%), than AM (33.3%) and
the subjects from the general population (40.8%).
MetHb level was directly proportional, and PCV
inversely related, to the duration of exposure. The
study suggested increased exposure to petrol fumes
among AM, PSA, and MetHb as a useful biomarker in
determining the level of exposure to benzene in petrol
vapour
EFFECT OF PROCESSED HORSE EYE BEAN (MUCUNA URENS L.) ON THE HORMONAL MILIEU OF MALE RATS
ARTICLE INFO ABSTRACT Purpose: To investigate the effect of processed horse eye bean (Mucuna urens L.), a soup thickener on serum level of some sex hormones: testosterone, follicle stimulating hormone (FSH), luteinizing hormone/interstitial cell stimulating hormone (LH/ICSH), estradiol and prolactin in male rats. Methods: Twenty male albino rats of 12 weeks old with similar body weights were assigned to four groups of 6 rats each and treatment with processed horse eye bean at 0, 100, 200 and 300 mg/kg body weight respectively daily for 8 weeks. Blood samples collected through cardiac puncture were assayed for levels of hormones. Results: There were dose-dependent effects of the processed horse eye bean on the serum concentration of the hormones. The treatment significantly reduced the levels of testosterone and FSH in the serum while it significantly increased the levels of estradiol, LH/ICSH and prolactin. Conclusions: Processed horse eye bean had strong capability to disrupt hormonal functions. Hence, its indiscriminate use as soup thickener could increase the risk of infertility in males
BIOLOGICAL RESPONSE OF MALE RATS TO AQUEOUS EXTRACT OF GINGER (Zingiber officinale ROSCOE)
ABSTRACT Purpose: To investigate the biological response of male rats to treatment with aqueous extract of ginger. Methods: Eighteen healthy and sexually mature male albino rats of 12 weeks old were used as the mammalian model for this study. They were assigned to three groups of six rats each and treated with aqueous extract of ginger at 0, 100 and 200 mg/Kg BW/day respectively for 7 days intraperitoneally. Blood was collected by cardiac puncture for hormonal assay. Cauda epididymes were dissected out, weighed and processed for epididymal sperm count. Results: Aqueous extract of ginger increased significantly (P<0.05) the weight of epididymes and epididymal sperm count. It also increased the serum levels of testosterone and follicle stimulating hormone (FSH), while it decreased the serum levels of estradiol, prolactin and luteinizing hormone/interstitial cell stimulating hormone (LH/ICSH). Conclusions: The androgenic and pro-fertility effect of the aqueous extract of ginger in the mammalian model makes it a possible fertility booster

Knowledge of HIV/AIDS Among Secondary School Adolescents in Calabar -Nigeria
Background:Awareness about HIV/AIDS has been created through the media,
workshops, and peer education and printed materials. The aim of this
study was to establish the impact of these awareness programmes on
student. Method:An observational study using structured questionnaire
among secondary school students. Results:About 181 (31.2%) of the
adolescents did not know the aetiological agents of HIV/AIDS. Majority,
522 (90%) knew HIV/AIDS was transmitted through sexual intercourse.
This level of knowledge was related to sex and class of study. Only 78
(13.4%) of them knew that HIV carriers might look normal. Majority, 519
(89.5%) did not know the features of AIDS. Only a few, 281 (48.4%) of
the adolescents knew that avoidance of sex, keeping one sexual partner,
15 (2.6%), use of condom 101 (17.4%) and screening blood before
transfusion, 31 (5.3%) could prevent HIV/AIDS transmission. Mass media
was the main source of information on HIV/AIDS to these adolescents.
About 191, (32.9%) of them believed HIV/AIDS cannot be prevented; 228
(39.3%) felt HIV/AIDS is common among the uneducated; 127 (21.9%)
thought it is not common in Nigeria and 143 (24.7%) believed it is not
common among the youths. Conclusion:Although awareness on HIV/AIDS is
high among Secondary School adolescents in Calabar, the knowledge of
the disease is still poor. Mass media as a source of information does
not allow in-depth knowledge of the disease. Parents, teachers, as well
as Health workers should be more involved in educating the youth on
this dreaded disease.Fond: la Conscience de VIH/SIDA a \ue9t\ue9 cr\ue9e par la

Low infection rates after 34,361 intramedullary nail operations in 55 low- and middle-income countries: Validation of the Surgical Implant Generation Network (SIGN) Online Surgical Database
Background: The Surgical Implant Generation Network (SIGN) supplies intramedullary (IM) nails for the treatment of long bone fractures free of charge to hospitals in low- and middle-income countries (LMICs). Most operations are reported to the SIGN Online Surgical Database (SOSD). Follow-up has been reported to be low, however. We wanted to examine the pattern of follow-up and to assess whether infection rates could be trusted. Patients and methods: The SOSD contained 36,454 IM nail surgeries in 55 LMICs. We excluded humerus and hip fractures, and fractures without a registered surgical approach. This left 34,361 IM nails for analysis. A generalized additive regression model (gam) was used to explore the association between follow-up rates and infection rates. Results: The overall follow-up rate in the SOSD was 18.1% (95% CI: 17.7–18.5) and national follow-up rates ranged from 0% to 74.2%. The overall infection rate was 0.7% (CI: 0.6–0.8) for femoral fractures and 1.2% (CI: 1.0–1.4) for tibial fractures. If only nails with a registered follow-up visit were included (n = 6,224), infection rates were 3.5% (CI: 3.0–4.1) for femoral fractures and 7.3% (CI: 6.2–8.4) for tibial fractures. We found an increase in infection rates with increasing follow-up rates up to a level of 5%. Follow-up above 5% did not result in increased infection rates. Interpretation: Reported infection rates after IM nailing in the SOSD appear to be reliable and could be used for further research. The low infection rates suggest that IM nailing is a safe procedure also in low- and middle-income countries.publishedVersio

REPRODUCTIVE TOXICITY OF PROCESSED SEEDS OF HORSE EYE BEAN (MUCUNA URENS L.) IN MALE RATS
ABSTRACT Purpose: To investigate the effect of processed horse eye bean (Mucuna urens L.), on weight of testes and epididymes, conception rate, sperm count, sperm viability and sperm head abnormality. Methods: Seventy-two mature albino rats (24 males and 48 females) of 12 weeks old with similar body weights were assigned to four groups of 6 male rats each and treated with processed horse eye bean at 0, 100, 200 and 300 mg/kg body weight respectively daily for 8 weeks. The male rats were made to sire the untreated female rats in the ratio of 1:2 for fertility test. The male rats were then sacrificed and the testes and epididymes were dissected out and weighed. The epididymes were processed for epididymal sperm count, viability and sperm head abnormality test. Results: Rats treated with processed horse eye bean showed no significant (P>0.05) effect on the weight of testes and epididymes, but treatment reduced the epididymal sperm count and sperm viability in dose-dependent manner when compared to the control. While it significantly (P<0.05) increased sperm head abnormality. The conception rates were significantly (P<0.05) reduced in a dosedependent manner and directly proportional to sperm viability and sperm count; and inversely proportional to sperm head abnormality in all the treatment groups. Conclusions: Processed horse eye bean still has some toxic effect on reproductive endpoints as well as conception rate. Hence, its indiscriminate use as soup thickener could result in reduction of spermatogenic activities and ultimately resulting in infertility, reproductive toxicity and dysfunctions
Social determinants of alcohol use among drivers in Calabar
Objective: Hazardous use of alcohol is a public health problem which accounts for 4.0% of global disease burden. Although the prevalence of alcohol use among drivers of commercial vehicles in Nigeria has been documented, not much is known about its social determinants. This study was, therefore, aimed at assessing the social determinants of alcohol use among drivers of commercial vehicles in Calabar. Materials and Methods: A cross-sectional descriptive study was conducted among 360 male commercial drivers. A semistructured questionnaire, which included the World Health Organization Alcohol Use Disorders Identification Test, was administered at interview. Binary and multinomial logistic regression analyses were used to identify social determinants of any and hazardous alcohol use. Results: Determinants of any alcohol use (binary logistic) were history of use by parents (adjusted odds ratios (AOR)=2.7; 95% CI=1.1–6.3), friends (AOR=3.2; 95% CI=1.3–7.8) and ready availability (AOR=4.1; 95% CI=1.9–8.8) while determinants of hazardous use (multinomial logistic) were history of use by parents (AOR=5.8; 95% CI=2.0–16.9), siblings (AOR=7.0; 95% CI=2.6–16.9), friends (AOR=6.6; 95% CI=1.8–24.4), hostile upbringing environment (AOR=3.8; 95% CI=1.3–11.1), use of other drugs (AOR=55.6, 95% CI=14.5–200), and respondents who had fathers with a maximum of primary or no formal education (AOR=4.6; 95% CI=1.8–11.8). Conclusion: Alcohol use was associated with family use, friends’ use, and use of other drugs. Multiple health education interventions are needed to tackle these challenges.Key words: Alcohol use, alcohol use disorders identification test, commercial vehicle driver
