Journal of the Nigerian Optometric Association , 2005,
Abstract: Infections of the external eye account for a significant percentage of ocular inflammations, some of which lead to visual losses as result of corneal involvement. This study purely isolated and identified the microorganisms most prevalent in external eye infections in Owerri urban (as seen Mercy Eye clinic). With the aid of sterile swabsticks, specimenswere collected from the lidmargins, conjunctiva and corneal surfaces, as the casemaybe, from infected eyes and streaked immediatelyon bloodandMacConkey plates for culture and analysis. The laboratory results revealed staphylococcus species 23.8%, Escherichia coli, 15.5%and admixture of bothmicroorganisms, 60.7%.

Indian Journal of Ophthalmology , 1991,
Abstract: One hundred consecutive cases of dry eye were studied to comment upon its epidemiological aspects. The incidence of dry eye amongst ophthalmic outpatients was 0.46% with a male:female ratio of 1:1.22. Fifty seven percent of the patients were above 50 years of age. The incidence was higher amongst outdoor workers and people from rural areas with poor socioeconomic status. The influence of hot and dry climate and nutritional status on dry eye incidence is discussed.

Journal of Food Technology , 2013, DOI: 10.3923/jftech.2012.50.58
Abstract: The influence of municipal wastes from selected dump sites in Imo State Nigeria, on the mineral and proximate contents of some crops found at the dumps was studied. The dump sites were located at Egbu-Timber road (5°31'57"N, 7°3'55"E) and World Bank layout (5°28'25"N, 7°1'10"E) in Owerri (both in Imo State, Nigeria). The Egbu Timber road dump is a tertiary dump site while the World Bank layout dump is a primary dump site. At the Egbu sample sites, the dump soil chromium content was 91.33% higher than that of the soil of the nearby normal farm. The farm crops also picked significant quantities of chromium. The nickel contents of crops should be watched as a substantial quantity was observed among the samples in relation to the soil nickel contents. There was also no substantial uptake of lead by the plants at this dump site. At the Owerri World Bank Housing Estate sample sites, some of the plants picked up some quantity of lead. There was a significant (p<0.05) pickup of vanadium by the dump pawpaw. The potassium contents of the crops at all the sample sites had the mineral values of the normal farm crops being much higher than those at the dump.

Abstract: Background: Timber workers, especially in developing countries, are faced with challenges of prevention and control of work place hazards and illnesses. Objective: To determine the awareness of occupational hazards, effects, safety and hygienic practices among timber workers in a South Eastern State in Nigeria. Methods: A cross sectional descriptive design that used the total population of timber workers involved in the processing and marketing of wood in three major timber markets in a South Eastern State in Nigeria. Data was collected using a pretested semistructured questionnaire. Descriptive analyses were done with frequencies and summary statistics. Results: The majority of the respondents were aware of the hazardous nature of wood dust (96%) and their main source of awareness was from personal experiences (55%). In spite of the fact that the predominant hazard effects in the majority were nose, throat irritation and cough (33%), the majority were of the opinion that the respirator was not important. Only 13% of the respondents that use personal protective equipment (PPE) always use them and the main reason for not using PPE is forgetfulness (38%). Proper hygiene and sanitation was poorly practiced, as all respondents indiscriminately disposed of waste wood (100%) and about one third (33%) did not have a bath after work each day. Conclusion: Timber workers in our environment are faced with increased risks of diseases, accidents and challenges of protection and safety. As a consequence, there is a need for proper education and enforcement of consistent use of the different protective devices.

Abstract: To determine the prevalence and pattern of occupational ocular injuries in sawmill workers in Nigeria. A cross-sectional study of sawmill workers was carried out using pretested questionnaires. Ocular examination was done on site with a pen torch, portable hand-held slit lamp bio-microscope and direct ophthalmoscope. The Statistical Package for Social Sciences (SPSS 16) was used to analyze the data obtained; p<0.05 was taken as significant. A total of 553 saw mill workers were studied of which 449 (81.2%) and 104 (18.8%) were technical and administrative sawmill workers respectively. There were 496 (89.7%) males giving a male to female ratio of 8.7:1. The mean age and standard deviation w as 38.9 years ± 12.8, respectively. The prevalence of work related ocular trauma was 10.7% with the technical worker being more likely to develop ocular injury than administrative worker (Odds ratio 15.3, p<0.001). Superficial foreign body, 42 (71.2%) was the most common presentation while anterior uveitis, 12 (2.2%) was the most common ocular disorder arising from trauma. Wood, 25 (42.4%) was the main agent implicated in the aetiology of the injury. Use of protective eye wear was in 7 (1.6%) technical workers while monocular blindness arising from injury at work occurred in 5 (0.9%) workers. Work related ocular injuries in sawmill workers in N igeria can be preventable if adequate safety practices are enforced.

Afrimedic Journal , 2012,
Abstract: Background: A stillbirth is a calamity and causes great distress both to parents and to the attending obstetrician or midwife. There is a paucity of information about stillbirths in Imo State, Nigeria. Aim : This study is to determine the causes and rate of stillbirths in Federal Medical Centre Owerri, Imo State, Nigeria. Method: This is a retrospective study of 296 stillbirths at st Federal Medical Centre, Owerri, between 1 of January2000 st and December 31 2004. Results: The stillbirth rate was 59.6/1000 deliveries. Most cases,208(72.7%), occurred in unbooked patients and nullipara accounted for 34.4% of cases. Most 126(44.1%) cases were in the 26-30 year age range and the major risk factors were pre-eclampsia 40(13.9%),abruptio placentae 39(13.6%), prolonged obstructed labour 30(10.5%)and prolonged pregnancy 28(9.8%). Conclusion: Most cases of stillbirth were preventable and could be avoided by simple measures like antenatal care booking, delivery under the care of skilled personnel and early referral to centres that could perform caesarean section. The role of congenital abnormalities needs to be researched as the absence of postmortem examination made it impossible to determine their contribution.

Journal of Medical and Biomedical Sciences , 2012,
Abstract: Because mining is an important industrial sector in many parts of the world, substantial progress has been made in the control of occupational health hazards associated with it. However, there are possibilities for further risk reduction. A cross-sectional study was conducted at Goldfields (Gh.) Ltd., Tarkwa to find out the prevalence of self reported eye diseases among the miners and visual hazards in the mine using standardized questionnaires. Four hundred and six (406) workers en-gaged in mining activity were conveniently sampled for the study. They all answered a question-naire that solicited information on their socio-demographic data, health history, vital eye safety information and eye screening. Tests performed included visual acuity and pinhole examination. Overall, 117 (28.8%) confirmed previous diagnosis of an eye disease with presbyopia as the most reported eye condition in 5.2% of the subjects. While visual impairment was found in 28.1% of the study population only 1.4% reported previous history of refractive errors. Flying dust was named as the potential eye hazard in the mine by 39.7% of the workers. Only 10% of the workers had had some form of eye injuries. Chemical usage was 41.1% among the respondents while 7.9 % com-plained about intensity of light at the workplace. Eye diseases and visual impairments were reported among miners. Visual hazards were also found in the mine. Eye protection controls should be strengthened and an occupational eye safety and health programmes integrated into the general safety programme of the mine.
Assisting the Blind and Visually Impaired: Guidelines for Eye Health Workers and Other Helpers
Sue Stevens
Community Eye Health Journal , 2003,
Abstract: As eye health workers, we give much attention to learning and teaching the importance of health education and the prevention and treatment of eye disease. Despite our gained knowledge, sadly, our efforts are not always successful and we are presented with the responsibility and challenge of caring for people who have to cope with visual impairment, perhaps for the rest of their lives. We have to understand their difficulties, recognise their abilities and learn how to cooperate and communicate with them in a social as well as hospital environment. It is often within the eye hospital itself that the lack in education of health workers and their understanding of the assistance needs of blind and visually impaired patients is all too evident.

Abstract: The research investigated the quality of ground waters in boreholes used as potable water (drinking water and other domestic purposes) in Owerri, Imo State, Nigeria. Three boreholes were randomly selected from numerous boreholes in Owerri. Water analyses were carried out for their physicochemical parameters, major ions, nutrients and bacteriological quality. The obtained average values from the analyses are: total iron (Fe) (mg/L) = 0.03, pH = 5.9, nitrate (mg/L) = 3.0, nitrate (mg/L) = nil. The observed average values were compared with standard values of the World Health Organization (WHO) for potable water. The results showed that the groundwater qualities from the selected borehole samples are generally low in dissolved constituents and therefore it recommends that borehole waters from areas around Owerri are generally acceptable as potable water for human consumption.
