Use of oral rehydration therapy in the treatment of childhood diarrhoea in Douala, Cameroon

Introduction The use of oral rehydration solutions in our context remains limited. This study was conducted to analyze the rate of this use in Douala, Cameroon and thereby determine the factors associated with it. Method A cross-sectional survey was administered to parents of children aged five years and younger during a six-month study period. The studied variables focused on the socio-demographic data of the population, data on diarrhoea and its severity, data on oral rehydration salts (ORS), and data related to other interventions for diarrhoea. The chi-square test was used to qualify associations between variables, with the significance level being set at 5%. Results Overall, 672 people agreed to participate in the study. Among them, 418 (62.2%) correctly defined diarrhoea. When their children develop diarrhoea, the majority of the parents (348, 51.8%) reported seeking hospital assistance before any intervention, while 225 parents (33.5%) preferred the use of ORS first. Four hundred seventy-five parents (70.7%) had heard of ORS and among them 313 (65.9%) had actually given ORS to their children as treatment during these children’s most recent episodes of diarrhoea. Of the parents who had given their children ORS, 217 (69.3%) knew how to prepare it, and 122 (39.0%) knew how to administer it. One hundred thirty-five parents (20.1%) had administered metronidazole to treat their children’s diarrhoea. The age of the children, the parents’ level of education, and the number of children in the household significantly influenced the use or non-use of ORS (respectively, p < 0.001, p = 0.003 and p < 0.0001). Rehydration was correctly identified by 234 parents (34.8%) as the purpose of administering ORS. Conclusion The knowledge and the use of ORS in diarrhoea by the study sample was insufficient. The role of ORS was poorly known. Awareness campaigns can be carried out in order to improve the use of this effective intervention for diarrhoea.

Influence of factors in the oral mucosa maturation pattern: a cross-sectional study applying multivariate analyses

Aim: To evaluate the association between oral health status, socio-demographic and behavioral factors with the pattern of maturity of normal epithelial oral mucosa. Methods: Exfoliative cytology specimens were collected from 117 men from the border of the tongue and floor of the mouth on opposite sides. Cells were stained with the Papanicolaou method and classified into: anucleated, superficial cells with nuclei, intermediate and parabasal cells. Quantification was made by selecting the first 100 cells in each glass slide. Sociodemographic and behavioral variables were collected from a structured questionnaire. Oral health was analyzed by clinical examination, recording decayed, missing and filled teeth index (DMFT) and use of prostheses. Multivariable linear regression models were applied. Results: No significant differences for all studied variables influenced the pattern of maturation of the oral mucosa except for alcohol consumption. There was an increase of cell surface layers of the epithelium with the chronic use of alcohol. Conclusions: It is appropriate to use Papanicolaou cytopathological technique to analyze the maturation pattern of exposed subjects, with a strong recommendation for those who use alcohol - a risk factor for oral cancer, in which a change in the proportion of cell types is easily detected.

Oral glutamate intake reduces acute and chronic effects of ethanol in rodents

Purpose: To assess the effects of oral glutamate intake on acute motor effects and chronic intake of ethanol in rodents. Methods: The acute effects of ethanol on motor function were studied in ICR mice by giving 2 or 6 g/kg of ethanol 2 h after distilled water or 2.5 g/kg glutamate per os. Thirty minutes after ethanol treatment, behavioral assays, including rotarod tests and foot print analysis were monitored. In chronic ethanol treatment, male Wistar rats were trained to consume ethanol-sucrose solution during a 2-h period daily, starting with 2 % ethanol/10 % sucrose and gradually increasing to 10 % ethanol/5 % sucrose solution over 56 days. After training session, the drug treatment phase was done for 10 days. The animals were force-fed 50 mg/kg/day topiramate or 2.5 g/kg/day glutamate 2 h before ethanol treatment sessions. Each day, ethanol intake, water intake, food intake and body weight were recorded. Results: Mice that received 2 or 6 g/kg of ethanol orally, showed a significant reduction in time on the rod in the rotarod test and a significant increase in both forelimb and hindlimb stride lengths when compared to control. Oral treatment with 2.5 g/kg of glutamate reversed the acute motor effects of ethanol. In chronic ethanol treatment, the intake of 10 % ethanol/5 % sucrose, accessible for 2 h, was significantly decreased in rats treated with either topiramate or glutamate. Conclusion: These results provide evidence that oral glutamate administration help to reduce the acute motor effects of ethanol in mice and ethanol intake in the chronic ethanol drinking rats.
