Psychometric properties of a self-assessment fear scale in children aged 4 to 12 years. Scary Scale.

BACKGROUND: Caregivers encounter difficulties differentiating fear and pain experienced by children and tend to interpret what children may feel, often resulting in inadequate pain management. While many pain self-assessment scales are available, there is no validated self-assessment fear scale for children. METHODS: The aim of this prospective study was to validate, in children aged 4 to 12 years, the psychometric properties of our scale. In a first part, in a school setting, five exercises were given to 484 children in order to validate the expression of fear, grade the intensity of the faces, the ability to discriminate the faces and the equality of the intervals. The scale's reproducibility was studied by assessing the children's fear in everyday situations at two different time points. In a second part, in a hospital setting, the aim was to test the scale's feasibility. Sixty children admitted to one emergency care department self-assessed their fear with the Scary Scale. FINDINGS: The expression of fear was validated by 57.64% (p < 0.0001) of the children in comparison with three other emotions (pain, surprise, sadness).The 7-9 year-olds validated the other properties (gradation, discrimination, equality, reproducibility). The 4-6 year-olds failed to validate the gradation exercise, but succeeded with the others. In the hospital, 95% of children self-assessed their fear using the scale. DISCUSSION: Our self-assessment fear scale was validated in children aged 7-12 years specifically and was readily feasible in the hospital. We recommend its use in that age group in every care situation triggering fear. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02675504.

[Heart failure due to non-infectious causes in developing countries: etiologic approach and therapeutic principles]. / Insuffisance cardiaque d'origine non infectieuse en zone tropicale: approche étiologique et principes thérapeutiques.

Cardiovascular disease is a major worldwide health problem with a growing impact in developing countries. Heart failure is the clinical manifestation of many advanced cardiac disorders. It can have numerous etiologies and the incidence of non-infectious causes is increasing with socio-economic development, thus illustrating the global nature of this epidemiologic transition. Several of the numerous non-infectious causes of heart failure involve cardiac diseases specific to tropical areas including dilated cardiomyopathy, endomyocardial fibrosis, and peripartum cardiomyopathy. Other widespread disorders are becoming more common as a result of the epidemiologic transition. Cardiovascular risk factors are changing particularly with regard to the incidence of coronary artery disease, ischemic cardiomyopathy, and hypertension-related complications. The purpose of this article is to provide an overview of non-infectious causes of heart failure in terms of frequency, onset, and therapeutic requirements. Symptomatic treatment of heart failure is same as in developing countries but is often delayed due to shortcomings in the care system.

[Diabetes mellitus in sub-Saharan Africa: epidemiological aspects and management issues]. / Le diabète sucré en Afrique subsaharienne aspects épidémiologiques, difficultés de prise en charge.

In contradiction with long-standing conventional wisdom that it is a rich country's disease, diabetes mellitus is increasingly a major concern in developing countries, especially in sub-Saharan Africa. Care facilities have not kept pace with the sharp increase in diabetes mellitus. The WHO has predicted a worldwide rise in the prevalence of diabetes that is expected to affect 300 million people by 2025. This progression is more flagrant in developing countries particularly in sub-Saharan Africa. In these countries, the expansion of diabetes is part of a broader epidemiological transition from transmissible diseases to non-transmissible diseases. A number of factors are causing this transition including aging of the population, sedentary lifestyle, and obesity. Aside from obesity, arterial hypertension is the main cardiovascular risk factor associated with diabetes. Alone or in association with other risk factors, diabetes mellitus accounts for high morbidity especially due to cardiovascular and kidney complications. Management in sub-Saharan Africa faces a number of issues: poor understanding of the extent of the problem, high cost of medications, socio-economic setting that is poorly suited to maintaining a proper diabetic diet, and limitations in infrastructure and personnel. The rapid increase in the prevalence of diabetes mellitus in sub-Saharan Africa is a serious challenge. There is an urgent need to obtain accurate figures about the extent of the pandemia as a basis for training an adequate number of health care personnel and implementing sufficient resources to allow local management. Meeting this challenge will require enhancement of the awareness and participation of all players involved in public health.

[General surgery and closed mitral commissurotomy: when necessity makes the rules]. / Chirurgien généraliste et commissurotomie mitrale à coeur fermé: ou quand la nécessité fait loi.

Since emergency transfer of patients from Africa to European cardiovascular facilities is difficult, surgeons at the Principal Hospital in Dakar, Senegal, have reevaluated closed mitral commissurotomy. The purpose of this study was to ascertain patient selection criteria, optimal operative conditions, immediate and middle-term outcome, and cost of closed mitral commissurotomy. From June 1995 to March 1998, closed mitral commissurotomy was carried out on 21 patients (13 women and 8 men). Inclusion criteria were symptomatic mitral stenosis with a mitral surface less than 1.5 square centimeters. Exclusion criteria were associated valve disease, Wilkins score higher than 8, severe pulmonary artery hypertension, and evidence of mitral thrombus. One patient died on the fourth postoperative day and one patient developed transient hemiparesis. Twenty patients showed significant functional improvement. Mean mitral surface increased from 0.87 to 1.8 square centimeters. Follow-up at one-year confirmed stable results. Only one patient developed grade 3 mitral insufficiency but it was well tolerated and did not require valve replacement. The cost of the procedure was 1,000,000 F CFA in second category and 820,000 F CFA in third category. The findings of this study show that closed mitral commissurotomy can be performed without circulatory assistance equipment in African facilities such as the Principal Hospital in Dakar, that immediate and middle-term results are excellent, and that African surgeons should continue to learn the technique.
