Field experiments were carried out to assess the impact of 100% NPK fertilizer recommendation (300 kg NPK 20:10:10), 100% Tithonia compost (TC), 75% NPK + 25% TC, 50% NPK + 50% TC, 25% NPK + 75% TC and control (non-fertilized plant) on the growth, fruit yield, nutritional and lycopene contents of three tomato varieties (Raoma VF; Ogbomoso local and Califonia wonder). The experiment was a split plot fitted into a randomized complete block design replicated three times. Data were collected on growth and reproductive parameters, fruit and seed attributes, and fruit proximate and nutritional contents. Data collected were subjected to analysis of variance to determine significant means. Significant varietal differences were observed among the tomato varieties in terms of growth, fruit yield and nutritional attributes. The plant dry matter yield was highest in Ogbomoso local and least in Roma VF. Fruit yield obtained with Ogbomoso local was 45 and 56% higher than what was obtained for Roma VF and Califonia wonder, respectively. In terms of vitamin C content, Roma VF fertilized with 50% NPK + 50% TC gave the highest value which is 23 to 67% higher than values obtained from the other treatment combinations. Again, irrespective of variety, organically grown tomato contains higher content of lycopene. It was also observed that the higher the proportion of TC compost in the treatments, the better the lycopene content. It could be concluded that the use of organic fertilizer has potential in improving the growth, fruit yield and nutritional contents of any of the three tomato varieties studied.

Objective: To assess the occupational exposure to needlestick and sharps injuries and hepatitis B vaccination status among dental auxiliaries. Subjects and Methods: A descriptive cross-sectional survey of 83 dental auxiliaries was conducted that included 12 technologists, 11 therapists, 53 nurses/surgical assistants, and 7 record officers. The survey included demography, history of needlestick and sharps injury, hepatitis B vaccination, knowledge and attitude towards HIV-infected patients, and the dental auxiliaries’ information needs on HIV-related issues. Results: Of the 83 dental auxiliaries, 34 (41%) had experienced needlestick and sharps injury in the last 12 months. At the time of the study, only 43 (51.8%) had been immunized against hepatitis B. 62 (74.7%) of the respondents thought that it was easier to contract HIV than hepatitis B through needlestick in a dental clinic. 21 (25.3%) would not assist dentists treating HIV-positive patients. However, 76 (91.6%), a majority, agreed that they needed more information on HIV-related issues, with 59 (71.1%) specifying a single area of need and 17 (20.5%) more than one area of need. The single areas of need specified in descending order were infection control (n = 22, 26.5%), HIV counseling (n = 12, 14.5%), oral manifestations of HIV/AIDS (n = 11, 13.3%), postexposure prophylaxis (n = 9, 10.8%), and antiretroviral therapy (n = 5, 6.0%). Conclusion: The data from this survey underscore the urgent need for educational interventions to encourage safe work practices. Hepatitis B vaccination, HIV-related knowledge and proper postexposure prophylaxis are needed to prevent occupational transmission of blood-borne viruses.

Introduction:The number of deaths due to trauma from road traffic accidents (RTAs), and from the use of firearms either for homicide or armed robbery, ethnic conflicts, and other events, such as flooding, explosions from petroleum products, and religious violence, is on the rise in Nigeria. This preliminary study is a comparative analysis of the frequency of deaths caused by RTAs and the deaths caused by the use of firearms during armed robbery. The study sought to identify the number of traumatic deaths caused by RTAs or armed robbery as well as the number of victims who sustained injuries in the process of RTA or armed robberies.Methods:An indigenous, non-governmental organization (NGO) network was used to abstract data for the frequency of RTAs associated with death or injuries and for deaths caused by armed robberies and was supplemented with data obtained from the Nigerian police.Results:For RTAs, the victims included drivers, passengers, and pedestrians. In 3,032 cases of RTAs, the total number of deaths was 1,239 (29.1%): one Nigerian dies for every three to four crashes. The total number of deaths due to RTAs was significantly higher than was the number of deaths due to the use of firearms in commission of robbery.Police reports relative to the use of firearms during armed robberies indicate that of a total of the 652 victims who were killed, 348 (68.1%) were the armed robbers, 134 (26.2%) were bystanders, and 29 (5.7%) were policemen.Conclusions:The enormity of the problems of traumatic deaths from RTAs and armed robberies in a developing country has been highlighted.

Periapical granuloma appears to be a less common periapical lesion in this study compared to the previous reports. In contrast to reports that relate to an acute flare of the lesion with abundant neutrophilic infiltration, this study has shown marked foamy macrophages and lymphocytes at the acute phase, which are significantly associated with the clinical diagnosis of acute apical periodontitis. We recommend the classification of periapical granuloma into early, intermediate, and late stages of the lesion, based on the associated inflammatory cells.
