ABSTRACT
Prematurity has been associated with Autism Spectrum Disorders (ASD), and the early diagnosis is relevant for this population. This study compares the frequency of positive screening for ASD signs using M-CHAT at 18-24 months (n = 60) and ABC questionnaires at 30-36 months (n = 58) of corrected age in toddlers born prematurely with birth weight < I500g and investigates ASD diagnosis in suspected cases. Toddlers screened positive were evaluated with a DSM-5 diagnostic protocol. 6.7% of toddlers screened positive for M-CHAT and 5.2% for ABC. ASD diagnosis was confirmed for 3.3% of children. An agreement between M-CHAT and ABC questionnaires was low (k = 0.241, p = 0.063). The frequency of suggestive signs of ASD detected by the M-CHAT and the ABC at different moments was similar, and the diagnosis rate of ASD was high. The screening at I8-24 month added to the screening at 30-36 months increased the frequency of positive screening for signs of ASD in preterm.
Prematuridade tem sido associada com Transtorno do Espectro do Autismo (TEA). Diagnóstico precoce é relevante para essa população. Este estudo comparou a frequência de rastreamento positivo para sinais de TEA utilizando os questionários M-CHAT aos 18-24 meses (n = 60) e ABC aos 30-36 meses (n = 58) de idade corrigida em prematuros nascidos com peso < 1.500 g e investigou diagnóstico de TEA nos casos suspeitos com protocolo diagnóstico seguindo DSM-5. Dos prematuros, 6,7% foram positivos para M-CHAT e 5,2% para ABC. Diagnóstico de TEA foi confirmado para 3,3% das crianças. Houve baixa concordância entre M-CHAT e ABC (k = 0,241, p = 0,063). A frequência de sinais sugestivos de TEA detectada pelos dois instrumentos em diferentes momentos foi similar; e a taxa de diagnóstico de TEA, alta. O rastreamento aos 18-24 meses, acrescido de rastreamento aos 30-36 meses, aumenta a frequência de rastreamento positivo para sinais de TEA em prematuros.

Diagnóstico de TEA fue confirmado en 3,3% de los prematuros. Hubo baja concordância entre M-CHAT y ABC (k = 0,241, p = 0,063).

El rastreo a los 18-24 meses, sumado al rastreo a los 30-36 meses aumenta la frequência de rastreo positivo para senales de TEA en prematuros.

Objective To study the etiology and antibiotic resistance of bloodstream infections in low birth weight preterm infants .Methods A total of 95 cases of bloodstream infections in low birth weight preterm infants were treated in our hospital from January 2011 to April 2014 .The clinical data of these patients were analyzed retrospectively .Results A total of 96 pathogens were isolated ,including 57 strains of gram‐negative bacilli ,38 strains of gram‐positive cocci ,and 1 strains of Trichosporon asahii .The most frequently isolated pathogens were Klebsiella pneumoniae (40 strains)and coagulase‐negative Staphylococcus(31 strains).All gram‐negative bacilli were sensitive to carbapenems such as imipenem and panipenem . Streptococcus isolates were sensitive to most antibiotics .Most Staphylococcus isolates were methicillin‐resistant ,which were highly resistant to common antibiotics but all sensitive to linezolid , vancomycin and teicoplanin . Conclusions The most important pathogens responsible for bloodstream infections in low birth weight preterm infants in our hospital are K lebsiella pneumoniae and coagulase‐negative Staphylococcus . Early identification of responsible pathogen and rational antimicrobial therapy are critical for good prognosis of bloodstream infections in low birth weight preterm infants .
