[What is the cost of treatment of diabetic retinopathy by argon laser in Yaoundé?] / Quel coût pour le traitement de la rétinopathie diabétique par laser argon à Yaoundé ?

PURPOSE: To evaluate the total cost of treatment of diabetic retinopathy by argon laser for a patient when indicated. PATIENTS AND METHOD: Prospective cross-sectional and descriptive survey, carried out in the angiography and laser center of the Yaoundé Central Hospital from October 2014 to October 2015. All consecutive diabetic patients with retinopathy and suitable indication for argon laser treatment were included. The costs related to the initial and final fluorescein angiography, the appointment for follow-up, round-trip transportation costs from the patient's home and the cost of laser treatment were included. RESULTS: Included were 43 (13 %) patients out of 330 with diabetic retinopathy. The mean age was 55.67±8.40years. There were 25 women (58.1 %) and 18 men (41.9 %) for a M/F ratio of 0.7. Unemployed patients were represented by 28 (65.1 %) versus 15 employed (34.9 %). Twenty-seven patients (62.8 %) were self-pay for all their expenses, 14 (32.6 %) were assisted by their families, and 2 (4.6 %) were insured. On average, the total expenditure was 86002±67197 f CFA per eye, corresponding to 131±102 euros with an exchange rate of 1 euro for 656 f CFA. CONCLUSION: The cost of treatment of diabetic retinopathy by argon laser is high, mostly increased by the additional costs related to transportation in our area. The creation of satellite centers in the 10 regions of Cameroon would reduce these costs.

Congenital rubella still a public health problem in Italy: analysis of national surveillance data from 2005 to 2013.

In accordance with the goal of the World Health Organization Regional Office for Europe, the Italian national measles and rubella elimination plan aims to reduce the incidence of congenital rubella cases to less than one case per 100,000 live births by the end of 2015. We report national surveillance data for congenital rubella and rubella in pregnancy from 2005 to 2013. A total of 75 congenital rubella infections were reported; the national annual mean incidence was 1.5/100,000 live births, including probable and confirmed cases according to European Union case definition. Two peaks occurred in 2008 and 2012 (5.0 and 3.6/100,000 respectively). Overall, 160 rubella infections in pregnancy were reported; 69/148 women were multiparous and 38/126 had had a rubella antibody test before pregnancy. Among reported cases, there were 62 infected newborns, 31 voluntary abortions, one stillbirth and one spontaneous abortion. A total of 24 newborns were unclassified and 14 women were lost to follow-up, so underestimation is likely. To improve follow-up of cases, systematic procedures for monitoring infected mothers and children were introduced in 2013. To prevent congenital rubella, antibody screening before pregnancy and vaccination of susceptible women, including post-partum and post-abortum vaccination, should be promoted. Population coverage of two doses of measles-mumps-rubella vaccination of ≥ 95% should be maintained and knowledge of health professionals improved.

Assessment of varicella underreporting in Italy.

We conducted a study to assess the degree of varicella underreporting in Italy, and its distribution by age group and geographical area. Underreporting in individuals from 6 months to 20 years of age was computed as the ratio between the varicella seroprevalence in 1996 and the 1996 lifetime cumulative incidence based on statutory notifications. The degree of underreporting at the national level was 7.7 (95% CI 7.4-7.9); underreporting was greater in older age groups and in southern Italy. Quantification of underreporting can contribute to better understanding of the burden of varicella and to evaluating the potential impact of mass vaccination.

Evaluation of the SIMI system, an experimental computerised network for the surveillance of communicable diseases in Italy.

In Italy, the current communicable disease notification system is organised as follows: in each region, Local Health Units (LHU) fill in and forward case report forms (CRF) to the Regional Health Authority, which send aggregated and individual notifications to several central-level institutions. In most regions, all data are recorded manually on hardcopy. Although most relevant data from CRFs are eventually entered into a computerised database at the National Institute of Statistics (ISTAT), the national database is only available 3-4 years later and no data-quality control is performed at that time. To improve the quality and timeliness of notification, in 1994, the Istituto Superiore di Sanità (the National Institute of Health) began to develop an experimental computerised surveillance network for communicable diseases (referred to as 'SIMI'). Specifically, a software was created and distributed to the LHUs and the Regional Health Authorities; staff training was performed; and feedback and analyses of collected data was promoted. SIMI was evaluated in the 13 regions that were participating in 1997 (out of a total of 20 regions in Italy), using criteria commonly used for surveillance systems (i.e., completeness and coherence of data, case definitions, costs, timeliness, and feedback). SIMI was implemented at a limited cost and the data collected were observed to have had a high degree of completeness and internal consistency. The SIMI system has since been adopted for the routine notification of communicable diseases in nearly all regions. Similar evaluations will be necessary for assessing the performance of the various notification systems used across Europe and to include them in a European network.

Health problems and socio-demographic findings in elderly Nigerians.

Nine hundred and fifty-one persons aged 60 years and over, living at home in four locations in southwestern Nigeria were studied. The cohort representing urban and rural dwellers, constituted 7.8% of the total population. Female residents had higher widowhood rates and lower levels of educational attainment than males. Multigenerational living arrangements were popular. Ninety-five percent of the cohort had no physical impairment on assessment of activities of daily life. Only 6.4% were on a regular pension (males more than females, P < 0.001) and income for 75% was less than the estimated poverty line (females more than males P < 0.001). Estimated crude death rate was also higher than the national average. The effects of these socio-demographic factors on health are diverse. Comparisons were made with similar studies in other cultures.

Attitude to aging among different groups in Nigeria.

Attitude to aging and the aged was surveyed in three groups of Nigerians, 1) caregivers living at home with the elderly, 2) various categories of hospital workers, and 3) the general public. Based on scores of an eleven-item questionnaire the best attitude was in caregivers, and the poorest in hospital workers. Years of education had an overall negative effect on attitudinal measurement. An inference from this study is that the elderly are still valued, but caregivers could be under some stress and would appreciate assistance. It is important for developing countries like Nigeria to begin to think seriously of what types of public assistance the elderly and their families would need.

Sonographic estimation of fetal liver weight: an additional biometric parameter for assessment of fetal growth.

A single fetal ultrasonogram was obtained between the 20th and 40th weeks of gestation in 327 pregnancies. Fetal body weight was calculated with standard methods and fetuses were classified as appropriate for gestational age (303 fetuses), large for gestational age (four fetuses), or small for gestational age (20 fetuses). Fetal liver weight was estimated on the basis of longitudinal, anteroposterior, and cephalocaudal liver dimensions multiplied by a constant (k) of 0.42 determined experimentally in a previous study of adult livers. Estimated liver weights in appropriate for gestational age fetuses were not statistically different from published standards based on autopsy findings (P < 0.005). Similar findings were obtained in two other normal pregnancies examined serially until delivery. Estimation of fetal liver weight appears to be an accurate and reproducible method and may enhance sonographic assessment of fetal growth abnormalities and conditions with fetal liver involvement.
