Unexplained neonatal jaundice as an early diagnostic sign of urinary tract infection
SummaryBackgroundHyperbilirubinemia is one of the presenting signs of bacterial infection in newborns, and the association of neonatal jaundice with urinary tract infection (UTI) has been particularly emphasized. The aim of this study was to determine the prevalence of UTI in asymptomatic jaundiced neonates younger than 4 weeks old.MethodsWe prospectively evaluated 120 asymptomatic jaundiced and 122 healthy neonates without jaundice younger than 4 weeks old for UTI. Patients with UTI, defined as >10 000 colony-forming units of a single pathogen per milliliter urine obtained by bladder catheterization, were evaluated for sepsis.ResultsOf 120 asymptomatic jaundiced neonates with a mean age of 7 ± 4 days, 15 (12.5%) had a UTI. Of 122 healthy neonates, positive urine cultures from a urine bag were found in eight cases; however on reevaluation, urine cultures from bladder catheterization were negative. The most common pathogen isolated from the UTI cases was Klebsiella pneumoniae. Also, unconjugated hyperbilirubinemia was detected in all jaundiced patients with UTI.ConclusionUTI was found in 12.5% of the asymptomatic jaundiced neonates with the onset of unconjugated hyperbilirubinemia in the first week of life. Therefore, we suggest that urine culture should be considered as a part of the diagnostic evaluation of jaundiced neonates older than 3 days with an unexplained etiology
Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections among pregnant women and eye colonization of their neonates at birth time, Shiraz, Southern Iran
Abstract Background Chlamydia trachomatis and Neisseria gonorrhoeae are the two common transmissible pathogens from pregnant women to their neonates. Given the lack of routine screening and treatment of pregnant women in some areas, the possibility of transmission rises. This study seeks to determine the prevalence of C. trachomatis and N. gonorrhoeae in the pregnant women with no clinical symptoms and the vertical transmission rate to their neonates. Methods The study was conducted on endocervical and eye swab samples of 239 pregnant women and their neonates. Identification was based on PCR method. Results The prevalence rates of C.trachomatis in women and neonates were 37/239 (15.5%) and 28/239 (11.7%), and for N. gonorrhoeae 3/239 (1.3%), 1/239 (0.4%), respectively. The vertical transmission rates to the neonates were 28/37(75.6%) for C. trachomatis and 1/3 for N. gonorrhoeae. Conclusions In the areas with a high prevalence of chlamydial or gonococcal infections, and in the absence of screening and treatment of the pregnant women, ocular prophylaxis with antibiotics is suggested as a part of routine neonatal care program for the prevention of chlamydial and gonococcal ophthalmia
Early cholestasis in neonatal lupus erythematosus
Neonatal lupus erythematosus is an immune-mediated disease caused by transplacental passage of maternal autoantibodies, primarily anti-Ro (SSA) and anti-La (SSB). The major clinical manifestations are congenital heart block, cutaneous lupus lesions, and hematologic problems. Hepatic, pulmonary, and neurological involvements are rare. We report a 5-day-old male neonate, born to a clinically asymptomatic mother, presenting with conjugated hyperbilirubinemia, cutaneous lupus lesions, congenital heart block, and thrombocytopenia. Both the neonate and his mother had high titers of antinuclear antibodies (1:640), anti-Ro (SSA), and anti-La (SSB) antibodies. The thrombocytopenia improved with prednisolone (2 mg/kg/day) for 14 days. The skin lupus rashes and bilirubin resolved 2 months later, and liver enzymes were completely normal by 6 months
