          Abstract

          OBJECTIVE: Early neurodevelopment disabilities (END) such as cerebral palsy (CP), deafness, blindness, epilepsy, and mental retardation (MR) are very important public health concerns. Although no strong data on END can be obtained in Mexico, the few papers concerning END epidemiology deserve systematic and critical review. Thus, this was the objective of the present paper. METHOD: We performed a systematic review of papers published reporting on the prevalence of END in Mexico. We performed a search in several medical data bases such as PubMed, Artemisa, ImBioMed, and LiLaCS. Each paper was downloaded, read and discussed. We only selected papers published between 1999 and 2008. RESULTS: No data on CP and epilepsy prevalence in infants have been found. Data on deafness prevalence report hearing loss in 0.65/1,000 healthy newborns, and in 2.6/100 in high-risk very premature infants. With regard to blindness, prevalence of retinopathy of premature infants in any stage was reported at ca 10.61 and 22.2/100 in high-risk premature infants. Congenital hypothyroidism (CH) prevalence in infants was found in 4.2/10,000 live newborns after a national universal screening survey. CONCLUSION: No universal data regarding the prevalence of END in Mexico have been investigated, with the exception of CH. Mexico needs more research to determine epidemiologic data focused on designing actions to prevent, treat, and rehabilitate END.

          OBJETIVO: Las neuro-discapacidades tempranas (NDT) como la parálisis cerebral (PC), hipoacusia, debilidad visual, epilepsia y retardo mental (RM) son problemas muy importantes de salud pública. Aunque no existen suficientes datos sobre la prevalencia de NDT en México, el objetivo de este trabajo es hacer comentarios sistemáticos y críticos sobre los ya estudios existentes. MÉTODO: Realizamos una búsqueda sistemática de artículos publicados sobre NDT en México. La búsqueda comprendió las siguientes bases de publicaciones: PubMed, Artemisa, ImBioMed y LiLaCS. Cada artículo fue descargado, leído cuidadosamente y comentado. Se seleccionaron aquellos trabajos publicados entre 1999-2008. RESULTADOS: No se han publicado datos sobre la prevalencia de PC y epilepsia en niños mexicanos. La prevalencia de hipoacusia se ha reportado entre 0.65/1,000 en recién nacidos sanos y 2.6/100 en recién nacidos de alto riesgo. La prevalencia de retinopatía de la prematurez como indicador de debilidad visual ha sido reportada entre 10.61-22.2/100 recién nacidos de alto riesgo. La prevalencia de hipotiroidismo congénito (HC) como indicador de RM ha sido encontrada en 4.2/10,000 recién nacidos en el estudio nacional de tamizaje. CONCLUSIÓN: No hay datos sobre la prevalencia de NDT con la excepción del HC en México. Se necesita más investigació

          Retinopathy of prematurity: a global perspective of the epidemics, population of babies at risk and implications for control.

          Globally at least 50,000 children are blind from retinopathy of prematurity (ROP) which is now a significant cause of blindness in many middle income countries in Latin American and Eastern Europe. Retinopathy of prematurity is also being reported from the emerging economies of India and China. The characteristics of babies developing severe disease varies, with babies in middle and low income countries having a much wider range of birth weights and gestational ages than is currently the case in industrialized countries. Rates of disease requiring treatment also tend to be higher in middle and low income countries suggesting that babies are being exposed to risk factors which are, to a large extent, being controlled in industrialised countries. The reasons for this "third epidemic" of ROP are discussed as well as strategies for control, including the need for locally relevant, evidence based criteria which ensure that all babies at risk are examined.

            Comparison of Epidemiological Data on Congenital Hypothyroidism in Europe with Those of Other Parts in the World

            The actual worldwide incidence of congenital hypothyroidism (CH) is based on the results of screening in parts of the world where screening is mandatory, i.e. most of Europe, USA, Canada, Cuba, Australia, New Zealand and Japan. In other parts of the world, some indications are given by the results of pilot studies. In Europe, mean overall incidence (1985-1990) for the countries included in our inquiry is 1/3801 – in each country for the same period: Austria 1/3,930, Belgium 1/3,750, Czechoslovakia 1/6,037, Denmark 1/3,777, Finland 1/3,969, France 1/4,132, FRG 1/3,827, Greece 1/3,314, Hungary 1/5,632, Israel 1/3,152, Italy 1/3,150, The Netherlands 1/3,723, Norway 1/3,069, Portugal 1/3,139, Spain 1/3,216, Switzerland 1/3,913, UK 1/3,398 and Turkey (pilot study 1989-1992) 1/2,943. In comparison, the figures for the USA for the whole country are similar for the mean overall incidence (1988-1990): 1/4,119. But large variations exist between the states, the reasons of which are perhaps related either to technical problems or to the ethnic background in each state. In Canada and Japan, modifications of screening procedures have led to similar figures for the last years in our possess, Canada (1986-1988) 1/3,884 and Japan (1990) 1/3,856. The figures (mean overall incidence) for Cuba (1987-1991) 1/2,325, for Australia (1985-1990) 1/1/3,331 and for New Zealand (1987-1990) 1/4,496 are quite comparable. So in these countries where the screening is established, no great variations are noted as in certain parts of the world with pilot studies: Argentine (Buenos Aires; 1985-1990) 1/4,407, Chile (1991-1992) 1/2,514, Brazil (Porto Alegre; 1987-1991) 1/4,429. In Mexico (1990-1991), it is 1/1,480; however, the overall incidence is higher, in the two pilot studies carried out in Ecuador. On the other hand, a pilot study carried out in São Paulo (1982-1991) on 1,794,051 tests is 1/14,352; the low incidence should be related to the ethnic background or/and techniques of screening.

              Prevalence of prelingual deafness in Italy.

              Neonatal hearing loss is the most frequent sensorial congenital defect in newborns. No data are available on worldwide prevalence of congenital deafness. World Health Organization (WHO) data indicate 1-4 cases per 1000 individuals, with a considerable increase in developing countries. A prevalence exceeding 1 per 1000 however, indicates a serious public health problem calling for urgent attention. Aim of the study was the evaluate the prevalence of prelingual deafness in the Italian population and determine the socio-demographic characteristics of the condition. Data were provided by the National Institute of Social Insurance (INPS) and the Italian Central Statistics Institute (ISTAT) and were collected in 18 out of the 20 Italian regions (98.2% of total population). All subjects recognized as deaf-mute by a special medical committee were included. According to law No. 509/1988, they had to present a mean bilateral sensorineural-hearing impairment, detected in neonatal age, which caused the damage in speech development and equal to 60 dB or more for 500-, 1000- and 2000-Hz frequency tones in the better ear. Prevalence rates were calculated according to region and age bracket using updated population data from census 2001. Statistical analyses were performed using the SPSS statistical software package. A total of 40,887 cases of prelingual profound sensorineural hearing loss > or =60 dB were detected in Italy in 2003, for a total prevalence rate of 0.72 per 1000. The hearing impairment prevalence differs according to sex. The overall prevalence is 0.78 per 1000 for males and 0.69 per 1000 for females (p 64 age groups reached 1.27 and 1.15, respectively. This phenomenon may have been due, in part, to the epidemic incidence of maternal rubella which occurred in the 40's and 50's (in Italy, the rubella vaccination was only recommended starting from 1972), and, in part, to the habit of contracting consanguineous marriages. Data from the Vatican Archives on 520,492 consanguineous marriages, for which dispensation was requested in the period 1911-1964, indicate that in the years 1935-1939, in small villages in South Italy (Basilicata, Calabria, Sicily) consanguineous marriages accounted for over 40% of marriages.
