Urinary Tract Infection in Infants <1 Month of Age: Demographic, Clinical, and Microbiological Characteristics.

BACKGROUND: This cross-sectional study was conducted on 232 infants aged <1 month with proven UTI admitted to three major teaching hospitals for the period 2010-2018 to assess clinical, demographic, and laboratory findings of urinary tract infection in this age group. METHODS: All information was extracted from the medical records. Urinary tract infection was defined as ≥ 50,000 colony-forming units per milliliter of a single uropathogen isolated from a catheterized or suprapubic aspiration or greater than 100,000 colony-forming units per milliliter from a midstream, clean-catch sample. RESULTS: The most common pathogen isolated was E. coli (78.4%), followed by Enterobacter and Klebsiella, accounting for 12.1 and 4.7% respectively. The main presenting clinical manifestation was jaundice, which was found in 54.7% of cases; it was followed by restlessness (45.6%) and fever (40%). CONCLUSION: During infancy, the signs and symptoms of UTI are often nonspecific and although urine culture is a gold standard diagnostic tool specimen collection is challenging and urine contamination is common in children, therefore it makes the diagnosis difficult. UTI in infants may indicate underlying genitourinary abnormalities; therefore, appropriate diagnosis and immediate initiation of antibiotic therapy are crucial to decrease long-term complications like renal scarring. According to our study, the most common clinical features were jaundice, restlessness, and fever, therefore it is suggested that urine culture should be performed for all infants presenting with these signs and symptoms.

Complications of COVID-19 Vaccines during Pregnancy; a Systematic Review.

Introduction: Rare serious complications have been documented after COVID-19 vaccination as clinical research proceeded and new target populations, such as children and pregnant women, were included. In this study, we attempted to review the literature relevant to pregnancy complications and maternal outcomes of COVID-19 immunization in pregnant women. . Methods: We searched the databases of PubMed, Scopus, Cochrane, and Web of Science on 31 August 2022. The records were downloaded and underwent a two-step screening; 1) title/abstract and then 2) full-text screening to identify the eligible studies. We included English original studies that evaluated the adverse effects of COVID-19 vaccines during pregnancy. Information such as the type of study, geographical location, type of vaccine injected, gestational age, maternal underlying diseases, and complications following the vaccination were extracted into pre-designed tables. Results: According to the findings of included studies, in most of them vaccination had a positive impact and no negative effects were observed. Also, no medical history was reported in 11 articles, and pregnant women had no underlying diseases. Some serious adverse events were reported after vaccination, including miscarriage, paresthesia, uterine contraction, vaginal bleeding, preterm birth, major congenital anomalies, intrauterine growth restriction, and seizure. . Conclusion: Because of limited data availability and the cross-sectional design of most studies, we could neither infer causation between vaccines and incidence of adverse effects nor comment with certainty about any possible adverse outcome of COVID-19 vaccines in vaccinated pregnant women. Consequently, more longitudinal and experimental studies are needed to define the exact adverse effects of COVID-19 vaccines in pregnant women.
