Urinary tract infection in full-term newborn infants: risk factor analysis

OBJECTIVE: To analyze the correlation of risk factors to the occurrence of urinary tract infection in full-term newborn infants. PATIENTS AND METHODS: Retrospective study (1997) including full-term infants having a positive urine culture by bag specimen. Urine collection was based on: fever, weight loss > 10 percent of birth weight, nonspecific symptoms (feeding intolerance, failure to thrive, hypoactivity, debilitate suction, irritability), or renal and urinary tract malformations. In these cases, another urine culture by suprapubic bladder aspiration was collected to confirm the diagnosis. To compare and validate the risk factors in each group, the selected cases were divided into two groups: Group I - positive urine culture by bag specimen collection and negative urine culture by suprapubic aspiration, and Group II - positive urine culture by bag specimen collection and positive urine culture by suprapubic aspiration . RESULTS: Sixty one infants were studied, Group I, n = 42 (68.9 percent) and Group II, n = 19 (31.1 percent). The selected risk factors (associated infectious diseases, use of broad-spectrum antibiotics, renal and urinary tract malformations, mechanical ventilation, parenteral nutrition and intravascular catheter) were more frequent in Group II (<0.05). Through relative risk analysis, risk factors were, in decreasing importance: parenteral nutrition, intravascular catheter, associated infectious diseases, use of broad-spectrum antibiotics, mechanical ventilation, and renal and urinary tract malformations. CONCLUSION: The results showed that parenteral nutrition, intravascular catheter, and associated infectious diseases contributed to increase the frequency of neonatal urinary tract infection, and in the presence of more than one risk factor, the occurrence of urinary tract infection rose up to 11 times.

Urinary tract infection in full-term new-born infants: value of urine culture by bag specimen collection

Objetivo : avaliar a eficacia da cultura de urina obtida atraves do saco coletor na deteccao de infeccao do trato urinario no periodo neonatal. Estudo retrospectivo (1997), englobando recem-nascidos de termo com urocultura positiva (>100000UFC/ml) colhida em saco coletor. Nesses recem-nascidos foi realizada puncao supra-pubica, coletando-se urina para cultura, para confirmacao diagnostica. Os recem-nascidos foram divididos em tres grupos, de acordo com a idade do recem-nascido na ocasiao da coleta...

Ulcera gastrica perfurada: doenca em ascensao em UTI neonatais? Particularidades neste periodo e relato de quatro casos / Perforated gastric ulcer: an ascending pathology in neonatal ICU?

A doenca peptica e pouco valorizada no periodo neonatal. Seu diagnostico e tratamento sao postergados ate que o neonatologista esteja frente a graves complicacoes, como perfuracao, hemorragia grave e morte. Este relato visa alertar sobre a presenca desta doenca no recem-nascido internado em UTI, salientando os possiveis fatores de risco para seu desenvolvimento e demonstrar sua importancia na etiologia das perfuracoes gastrointestinais deste periodo
