In children, kwashiorkor is rare but malnutrition is observed mainly in female babies between 1 and 3 years. It is caused by on the one hand a too late and too rapid weaning, and on the other hand to ancestral habits giving priority care to male babies. In adult populations, the main fact observed is an over-weight in women, with subsequently, a higher rate of blood hypertension and cerebro-vascular accidents than in men. This over-weight is a symbol of wealthiness and resorts to a traditional pattern of feminine beauty. Public health service and nutrition education can promote the use of a larger variety of foods which has little possibility of changing quickly an esthetic mode. But this concept will slowly recess, according to new ways of life.

Its purpose was to evaluate the importance of xerophthalmia. 3.002 children under 10 years of age were surveyed for two different periods: in 1984 after the drought striking the Sahelian zone and in 1985 after a normal crop. Computerization of the results according to nutritional circumstances and geographical distribution demonstrated that avitaminosis is a true Public Health problem, whatever climatic zones, food products and nutritional conditions are. However situation worsens during a drought and calls for an emergency distribution of vitamin A to the most-in-need populations.

Two of them are children and in two cases there had been a local traumatism.

Participants: Consecutive patients undergoing surgery for age-related cataract between December 2016 and August 2017 at two non-governmental organization (NGO) hospitals (Lagdo and Kousseri) in northern Cameroon. Methods: The Better Operative Outcome Software Tool (BOOST) app was used to collect data on visual acuity (VA) before and one day after surgery. Reasons for poor visual outcomes were recorded for 20 consecutive patients returning >6 weeks after surgery with VA<6/60. Main outcome measures: Proportion of patients with good (VA ≥ 6/18), borderline (VA 6/60–6/18), and poor (VA<6/60) results, and cause of poor results: refractive problems, surgical complications or presence of ocular comorbidities. Results: In total, 148 patients (148 eyes) in Lagdo and 91 patients (91 eyes) in Kousseri were evaluated. Mean (Standard deviation [SD]) age was 62.1 (8.0) years (54.1% male) in Lagdo and 65.7 (11.1) years (56% male) in Kousseri. Most patients (63.4% in Lagdo, 64.9% in Kousseri) were blind in the surgical eye pre-operatively. Good, borderline and poor surgical outcomes were present on Day 1 in 6.8%, 62.1%, and 31.1% in Lagdo (3rd percentile among BOOST users) and 2.2%, 65.9% and 31.9% in Kousseri (2nd percentile). Main reasons for poor surgical outcomes were ocular comorbidities in Lagdo (19 among 21 patients) and refractive errors in Kousseri (8 among 13 patients). Conclusions: BOOST placed surgical results into context, and identified main causes of poor outcomes in each center.

The objective of the study was to assess the impact of installing water supply boreholes on the incidence of trachoma. A prospective group of 4 villages, where boreholes were sunk at the beginning of the study, was compared to a control group of 4 villages where there are no boreholes. The examination concerned children below the age of 10 years (N = 700) and was carried out using binocular loupes, according to the simplified procedure for trachoma grading proposed by the WHO. Our results show that in the prospective group, the annual rate of incidence of inflammatory trachoma was 8% (cl: 5.8-10.7) while in the control group it was 14% (cl: 9.6-10.9). RR: 0.58 (0.37-0.90). Likewise the rate of spontaneous healing was 12% (Cl: 9.1-14.9) in the prospective group and 5% (cl: 2.4-9) in the control group. Relative Risk was 2.60 (1.36-4.9). These statistically significant results show that the risk of contracting trachoma is reduced by half in the villages where a borehole has been sunk.

Une evaluation retrospective (1995 a 2001) du nombre de cataractes operees par secteurs d’activite, par centres de soins oculaires et par millions d’habitants ( Cataract surgery rate, CSR) est menee a partir des registres des centres de soins (nombre de cataractes operees), de la direction des Statistiques (population des regions) et le CSR est calcule. Entre 1995 et 2001, 3 885 cataractes ont ete operees. Le secteur public concentre 53,05 % des interventions (n = 2 061) suivi du confessionnel, 37,1 % (n = 1 443), les soins decentralises 6,2 % (n = 241) et le secteur prive 3,4 % (n = 143). Cinq cent cinquante-cinq cataractes sont operees par an et 43 par centre. Le CHU de Tokoin concentre 32,5 % des operes (n = 1 262), suivi de l’hopital confessionnel de Glei 27,2 % (n = 1 058). La repartition des services de soins est inegale avec 41 % (n = 1 586) des operes a Lome ou le CSR moyen est de 334. Le CSR moyen global est de 126 et de 181, 112, 80, 79 et 52 respectivement pour la region des Plateaux, Kara, Centrale, Savanes et Maritime (sans Lome). Les indicateurs de la chirurgie de la cataracte au Togo sont inferieurs aux donnees regionales subsahariennes. On a observe une legere augmentation du nombre de cataractes depuis 1999. La prise en charge de la cecite par cataracte au Togo reste insuffisante. Il faut augmenter les ressources, developper les soins decentralises et motiver les malades pour qu’ils se fassent operer.

From 1990 to 1995, a total of 22 cases of corneal ulcers involving Acanthamoeba sp. were diagnosed at the IOTA. To improve our understanding of the epidemiological characteristics of these lesions in tropical areas, we attempted to identify healthy carriers of Acanthamoeba sp. by studying the normal eye flora of 149 patients examined at the IOTA in February 1996. Acanthamoeba sp. was not detected in any sample. Fungi were detected in 22.15 p. 100 of the samples. Thus, it would appear that, unlike fungi, Acanthamoeba sp. is not present in normal eye flora in Mali. This findings suggests that the occurrence of Acanthamoeba in corneal ulcers is not an accident. Our results also emphasize the need for screening to detect Acanthamoeba in developing countries such as Mali. However, further study will be needed to confirm these findings in a larger group of subjects more closely matched with the patients presenting the corneal ulcers diagnosed at the IOTA, especially with regard to geographical origin.
