Tactile Acuity among Commercial Motorcyclists in Uturu, Nigeria.

Aims: To determine and compare tactile acuity of commercial motorcyclists with that of their age and sex matched controls. Study Design: Cross sectional study. Place and Duration of Study: The study was done in Uturu, a suburban university town in South Eastern Nigeria, from July 2014 to August 2014. Methodology: We determined two point discrimination threshold distances on the right thumbs of two hundred (200) consenting commercial motorcyclists aged between 18 to 60 years and two hundred (200) of their age and sex matched controls. Results: The mean values of two point discrimination threshold distances were 6.03 mm (Standard Deviation = 2.484) and 4.31 mm (Standard Deviation = 2.046) in the test and control subjects respectively (t =7.558; p < .001). There was positive linear association between two point discrimination threshold distance and the age of the subjects, and their duration of operation as commercial motorcyclists (r = .752; p < .001 and r = .770; p < .001), respectively. Duration of service as a commercial motorcycle operator (p < .001), age (p = .004) and impaired sense of fine touch (p < .001) were independent predictors of deficits in tactile acuity. Conclusion: Tactile acuity was impaired in the assessed Nigerian commercial motorcycle operators compared with their controls. Measures of mitigating effects of the occupation on tactile acuity should be explored.

Footcare practices among Nigerian diabetic patients presenting with foot gangrene

Diabetic foot ulceration and gangrene is a major cause of morbidity andmortality. This study has examined potential preventive footcare practices in a cohort of diabetic patients presenting with foot gangrene. One hundred and two (102) diabetic emergencies presented during the study period. Diabetic foot gangrene accounted for 27 (26%) of these cases. There were 18 males and 9 females (M:F = 2:1), with a mean age of 52+13 years. The mean duration of ulceration was 4±3 weeks and mean ulcer­gangrene interval was 1.2±0.5 weeks. Only 9 patients (33%) had been exposed to any form of footcare education, 15 patients (55%) treated their ulcers by unorthodox means, and 63% of the patients practiced no significant footcare. More widespread education and awareness is needed to prevent the continuing and serious problem of diabetic foot gangrene and consequent lower limb amputation
