Drinking good quality water is essential for better health. It is therefore essential to assess the radiological quality of all water consumed in the District of Abidjan in order to prevent related hazards. Thus, the objective of this study was to assess the risk of cancer due to the ingestion of alpha and beta emitting radionuclides in the different types of water consumed in the region. A total of 63 water samples with 43 tap water samples, 5 bottled mineral water and 15 sachet water samples was collected and taken to GAEC laboratory for analysis. The low background Gas-less Automatic Alpha/Beta counting system (Canberra iMaticTM) was used to determine alpha and beta activity concentrations. Activity concentrations of both gross alpha and gross beta obtained in water sample were respectively lower than the WHO recommended limits of 0.1 Bq/l and 1 Bq/l. Also, the annual effective dose and total equivalent effective dose found in mineral bottled water samples were higher than in other types of water. The assessment of radiological lifetime risk has shown values of cancer risk due to ingestion alpha and beta emitters lower than recommended limit. These results indicate that there is no health hazard associated to consumption of water in the District of Abidjan.

Prolapsed Juvenile Polyp of the Anus in 2 Cases

Open Journal of Pediatrics 2023年第6期13卷 785-790页

Introduction :Rectal polyps are well-circumscribed, sessile or pedunculated formations that develop on the digestive mucosa. Juvenile polyps are seen in 4% - 12% of cases during pediatric colonoscopies. In children, rectal bleeding is a frequent warning sign, often a recurrent bleed with no impact on general condition. Diagnosis is based on clinical, imaging and digestive investigations, but anatomopathological examination remains the only means of confirmation. There are a number of treatment options, ranging from abstention to surgical excision. We report two (2) cases of isolated hemorrhagic juvenile polyp prolapsed to the anus in order to analyze the diagnostic and therapeutic features of this pathology. Patients and observations: A 7-year-old female patient presented to the pediatric emergency department of the Donka National Hospital with a hemorrhagic anal mass. On clinical examination, the patient was found to be in satisfactory general condition, with a hemorrhagic pedicle mass prolapsed to the anus. The mass was removed under general anesthesia. Postoperative management was straightforward. Conclusion: Juvenile polyps are the most common proctological condition in this age group. Clinical examination must be meticulous, as certain signs may point to a particular pathology. Colonoscopy is the diagnostic test of choice, and can also be used as a therapeutic tool.

Looking of finding an alternative to the use of chemical fertilizers to increase yields of cassava (Manihot esculenta), trials were carried out in the Lamto zone in central Côte d’Ivoire. Thus, the effects of compost and ash from cocoa shell and NPK were tested on the agronomic parameters of cassava. The trial was conducted for two years with four varieties of cassava: Yacé, Alleda agba, Six mois and Bonoua, grown on elementary plots treated with one of these fertilizers. The experimental design was complete randomized blocks with three replicates. Analysis of the results showed that the Six mois variety gave the longest stems (131, 67 cm) with the cocoa shell compost. The Bonoua variety, on the other hand, gave the largest diameter of the stem base (21.56 mm), a higher number of leaves (77.30) and a large wingspan (136.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease deadly. In Africa, little data exists on this condition and the form familial is the most common with a younger age of onset. Our observations relate to three brothers, born from a consanguineous marriage. The diagnosis of amyotrophic lateral sclerosis was certain placed in all patients according to the criteria of Awaji. The average age of patients was 16.66 years, and the average age of onset of symptoms was 10.33 years old. The female gender was the most represented with a sex ratio of 0.5. Our patients benefited from rilusole, vitamin D and physiotherapy. A only patient presented with dysphagia. However, no cases have been observed at this day.
