    Background: Peripheral arterial disease (PAD) is rarely sought for and generally underdiagnosed even in diabetics in developing countries like Nigeria. PAD is easily detected and diagnosed by the ankle-brachial index, a simple and reliable test. Objectives: To determine the prevalence of PAD in diabetic subjects aged 50–89 years and the value of ankle-brachial index measurement in the detection of PAD. Method: A cross-sectional descriptive study of 219 diabetic subjects aged 50–89 years was carried out. The participants were administered a pre-tested questionnaire and measurement of ankle-brachial index (ABI) was done. The ankle-brachial index < 0.90 was considered equivalent to peripheral arterial disease. Results: The overall prevalence of PAD was 52.5%. The prevalence of symptomatic PAD was 28.7% whilst that of asymptomatic PAD was 71.3%. There were a number of associations with PAD which included, age (p < 0.05), sex (p < 0.05), and marital status (p < 0.05). The use of the ankle-brachial index in the detection of PAD was clearly more reliable than the clinical methods like history of intermittent claudication and absence or presence of pedal pulses. Conclusion: The prevalence of PAD is relatively high in diabetic subjects in the southwestern region of Nigeria. Notable is the fact that a higher proportion was asymptomatic. Also the use of ABI is of great value in the detection of PAD as evidenced by a clearly more objective assessment of PAD compared to both intermittent claudication and absent pedal pulses

    Background: Hysterosalpingography (HSG) is a valuable radiological procedure for imaging the female reproductive tract. This study highlights the spectrum of HSG findings among women presenting for gynaecological imaging in a tertiary health institution in Ado-Ekiti, South western Nigeria.Methods: A prospective cross sectional study was conducted between October 2014 and September 2015. The study population consisted of 134 women presenting at the Radiology department with request forms for HSG. Pelvic ultrasonography was done using a 3.5MHz transducer prior to HSG. Imaging findings were documented, results were entered into a spread sheet and analysed using SPSS version 20. Chi square was used to determine association between tubal occlusion, age, type of infertility and previous history of surgery. Statistical significance was set at p-values &lt;0.05.Results: The age range of the study participants was between 23 to 50 years with a mean age of 34.9±5.53years. Age group 30-34 years (n=43, 32.1%) constituted a majority. Secondary infertility (n=84, 62.7%) was the most common clinical indication for HSG. The predominant relevant past surgical history was uterine evacuation (n= 41, 30.6%). Normal HSG findings were seen in 34 (25.4%) of the patients while others (n=100, 74.5%) had various abnormalities, the most common of which were tubal pathologies (n=89, 66.4%). There was a significant association between age and tubal occlusion (P=0.02).Conclusions: HSG is still a relevant gynecological imaging modality in resource limited settings. Tubal occlusion was the most common abnormal HSG finding in this study. There is a need for continuous advocacy on preventive measures targeted at reducing the incidence of tubal pathologies among women in developing countries

    Air drying polyesteramide-urethanes resins were synthesized from Thevetia peruviana seed oil commonly known as Yellow oleanda (a tropical ornamental shrub) having about 68.8% unsaturated and 30.9% saturated fatty acids. The physico- chemical characterization of the optimized unsaturated FAME such as hydroxyl value, iodine value, saponification value, refractive index, inherent viscosity were carried out using standard methods. Through condensation reaction the N,N'- bis(2-hydroxyethyl) Thevetia peruviana (HETA) prepared from the FAME reacted with isophthalic acid to form polyesteramide. The latter undergo urethanation with H1 ' 2MDI. The structural elucidation of the moisture cured polyesteramide-urethane coating was based on FTIR, 1H-NMR and 13C-NMR spectroscopic methods. The coatings films were evaluated for its antihacterial activity and thermal stability properties on TGA and DSC. The SEM of the --uating films was also examined

    The use of renewable resources for the development of coating materials is a viable means to reduce environmental impact and support sustainability efforts. This paper describes a novel antimicrobial polyesteramide-urethane-silica- Zinc Oxide (ZnO) hybrid coatings based on milk bush seed oil as renewable resource. Initially ZnO nanoparticles were modified with aminopropyltrimethoxysilane to get silica grafted ZnO composite particles. The milk bush oil based polyesteramide were reacted with excess H12MDI to get NCO terminated polyesteramide-urethanes and the excess NCO was reacted with silica grafted ZnO composite particles to get the reactive hybrid prepolymers. These prepolymers were casted on tin foil and cured under atmospheric moisture to get eco-friendly moisture curing polyesteramide-urethane-silica- Zinc Oxide (ZnO) hybrid coatings films. The coatings films were evaluated for its antimicrobial and thermo mechanical properties while coated steel specimen were used for corrosion studies. The techniques such as FTIR, TGA, DSC, DMTA, SEM and XRD have been used in this study. The hybrid coating films has shown very good antibacterial and antifungal propertie$, higher thermal stability and better thermo mechanical properties. The improvement in the properties was dependent" on the concentration of ZnO composite particles in the coating films. The antibacterial experiments show that the ZnO doped films exhibit excellent antibacterial activity, especially for E.coli. The salt spray test on coated specimen show good corrosion resistance properties for hybrid coating
