The prevalence of syphilis in pregnant women in Akwa Ibom State, Southern Nigeria

Background: Treponema pallidum, the causative organism of syphilis has been a public health challenge for centuries. Syphilis is a significant cause of morbidities and mortalities in pregnant women, and information regarding its prevalence in Nigerian pregnant women is scanty particularly from the south‑south zone.Objective: To determine the prevalence of syphilis in women receiving antenatal care in twelve health care centres in Akwa Ibom State, Nigeria.Methodology: Pre‑coded structured questionnaires were administered to 911 participants over an eight week period. Venous blood samples were collected from each participant and tested with a Treponema pallidum immunochromatographic test.Results: There were about 18 women (1.98%) tested positive to syphilis. Prevalence rates in urban and rural areas were 2.63% and 1.32% respectively. The women from urban areas had a 3.22 (95% CI 1.05‑9.85) increased risk of acquiring syphilis when compared to the rural dwellers. Women with tertiary level of education had a significantly reduced risk of acquiring syphilis compared to those with primary level education while having an unemployed husband increased the risk of acquiring the infection by 10 times.Conclusion: Though VDRL is part of routine antenatal care screening, a policy of its use in the screening of all women receiving antenatal care in Akwa Ibom state should emphasized and it should be incorporated into the state Government’s free antenatal care program. Preferably, a single rapid test should be employed for screening, so that women testing positive could be treated at same clinic visit. Economic empowerment of women should be accorded priority and the practice of safe sex and use of contraception, especially barrier methods should be promoted.Keywords: Akwa Ibom state; antenatal attendees; prevalence; syphili

A review of the prevalence and rate of utilisation of measures offered to HIV-positive women during delivery in a tertiary hospital in south-south Nigeria

Background: Vertical or mother-to-child transmission of HIV which accounts for over 90% of paediatric HIV infection is increasingly becoming a major mode of transmission in  developing countries. Aim: To determine the prevalence of HIV infection among pregnant women that deliver at the University of Uyo Teaching Hospital and also review the interventions they are offered when they present in labour. Methods: The case records of all HIV positive patients who delivered between 1st July 2005 and 31st December 2007 were reviewed. Results: There were 2,851 deliveries out of which 188 patients were HIV positive giving a prevalence of 6.6%. The modal age group of the HIV-positive patients was 26-30 years (40.4%). Most (68.6%) of the patients were multiparous and 89.3% of them had regular antenatal care in the hospital. HIV was diagnosed in the antenatal clinic in 71.8% of the patients.  Most (72.3%) of them had a single dose of nevirapine in labour while 5.8% received highly active anti-retroviral therapy. About 63.8% of the patients had spontaneous vertex delivery while 33.5% were delivered by Caesarean section. All the babies had single doses of nevirapine within 72 hours of birth. Most (84.0%) of the mothers chose to feed their babies exclusively with breast milk substitutes. There were 3 maternal (1.6%) and 16 (8.5%) perinatal deaths. Conclusion: The prevalence of HIV infection among women who deliver in our hospital (6.6%) is relatively high. The treatment of HIV positive pregnant women in labour with respect to the prevention of mother-to-child transmission fell short of acceptable standards in some of our patients. Efforts should be made to ensure the adoption of anti-retroviral therapy as recommended in the Nigerian national guidelines.   Keywords: HIV prevalence, Delivery, Vertical transmission, Prevention, Uy

Contraceptive practice in a tertiary hospital in south-south Nigeria

Background: The high maternal and infant mortality in sub-Saharan Africa has been associated with unplanned pregnancy, high parity and short birth intervals. Use of effective contraceptive methodssignificantly reduce maternal and infant mortality and improved quality of life. This study determines the contraceptive practice among clients in a tertiary hospital. Method: The record cards of all clients that accepted contraceptive methods in the family planning clinic at the University of Uyo Teaching Hospital, Uyo over a 7-year period were reviewed. Results: There were 1094 new contraceptive acceptors during the study period. The modal age group of the clients was 25 – 34 years (59.3%); majority of the clients were multiparous (59.8%), christians (99.6%) and 71.0% had at least secondary school education. The most commonly accepted contraceptive methods were the intrauterine contraceptive device (45.0%) and oral contraceptive pills (28.1%), while clinic personnel (63.1%), and friends and relatives (20.1%) were the most common sources of information on contraception. Conclusion: Intrauterine contraceptive device and oral contraceptive pills were the most frequently accepted methods of contraception. We advocate increase in the contraceptive options including implants. The print and electronic media should be more involved in the awareness programs on contraception

Phytochemical Screening and Antibacterial Activities of Aframomum melegueta (K. Schum) Seed Extracts on Salmonella typhi and Klebsiella pneumoniae

The phytochemical screening and antibacterial effects of Aframomum melegueta (K. Schum)on Salmonella typhi and Klebsiella pneumoniae was carried out. The phytochemical screening revealed the presence of alkaloids, flavonoids, tannins, saponins, steroids, anthraquinones, terpenoids, glycosides  and phenols in the seed extract. The susceptibility test showedzones of inhibition (ZOI) of S. typhi (11.0mm) and K. pneumonia (13.0mm)with methanolic seed extract (MSE), while the hot aqueous seed extract (HASE) recorded 3.0mmas ZOI for both test organisms. The Minimum  inhibitory concentration (MIC) of 200mg/ml and 100mg/ml were recorded against S. typhi and K. pneumoniae respectively with MSE, while HASE indicated 400mg/ml and 200mg/ml MICs against S. typhi and K. pneumoniae respectively. The Minimum Bactericidal Concentration (MBC) obtained from MSE were 200 mg/ml and 25mg/ml for S. typhiand K. pneumoniae, while HASE had > 400mg/ml for test microbes. The effectiveness of different concentrations of the test plant extracts on the test organisms was significant (P<0.05). Further trials involving other clinical isolates and botanicals at different concentrations be conducted, to optimize theprocess.

Assessment of Biodiesel Fuel Potentials of Seed Crude Oil Extracts of Balanites aegyptiaaca (L.) Del

Study on assessmentof biodiesel fuel potentials of seed crude oil extracts of Balanites aegyptiaaca (L.) Del was carriedout. Standard methods of the Association of Official and Analytical Chemist (AOAC) were adopted to evaluate the proximate, physico-chemical properties and fatty acid  compositions of crude seed oil extracts of the test plant. The proximate constituents of the crude seed oil extract gave crude protein (22.09%), crude fat (56.75%), moisturecontent (1.35%), ash (4.70%), crudefiber (12.75%) and carbohydrate (2.36%). The crude oil physicochemical properties included saponification value(216.439mgKOH/g), peroxide value(4.84meq/kg), acid value(2.18mgKOH/g), iodine value(77.08g/100g), viscosity  value(150.3@30°C) and cetane number(54.08), refractive index(1.487 @30°C), relative density (0.949g/cm3) while calorific value was 39.03(MJ/kg). The fatty acids composition of crude kernel oil extract of B. aegyptiaca indicated the presence of four (4) fatty acids, with relative percentage abundance (RPA) in the order of 67.17% (9,12-Octadecanoic acid (C19 H3402)) > 16.22% (Pentadecanoic acid (C17H3402)) > 11.8kg% (Heptacosanoic acid (C28H5602)) > 4.72% (Oleic acid(C18H3402)). These properties conferred relative prospects on the crude oil of the test plant as a suitable  potential biodiesel substrate and consequently, large scale aforestation efforts be renewed, to guarantee ready availability of the raw materials.

Sarcopenia: its assessment, etiology, pathogenesis, consequences and future

Sarcopenia is a loss of muscle protein mass and loss of muscle function. It occurs with increasing age, being a major component in the development of frailty. Current knowledge on its assessment, etiology, pathogenesis, consequences and future perspectives are reported in the present review. On-going and future clinical trials on sarcopenia may radically change our preventive and therapeutic approaches of mobility disability in older peopleY. Rolland, S. Czerwinski, G.
