Background: Ritual circumcision in neonates may cause a urinary tract infection within 2 weeks of the procedure.

Objectives: To evaluate the prevalence of urinary tract infection among Jewish male circumcised neonates (¡Ü 28 days old) evaluated for fever in the emergency room.

Methods: All available medical records of neonates presenting to the pediatric emergency room for evaluation of fever over a 10 year period were reviewed. Data included gender, ethnic background, age in days on presentation to the emergency room, age in days when circumcision was performed (in males ¡Ý 8 days of age), and results of urine, blood and cerebrospinal fluid cultures. Families of males older than 8 days of age who had a UTI[1] were contacted by telephone to verify the circumcision status when the infant presented to the ER[2], to ascertain whether the circumcision was performed ritually by a mohel* or by a physician, and, when not recorded in the chart, to verify the day of life on which circumcision was performed.

Results: Among neonates older than 8 days of age, 60 (24.7%) of the 243 febrile Jewish males had a UTI, as compared to 12 (8.4%) of 143 females (P < 0.0001). In 39 of 54 male neonates (72%) for whom circumcision was performed ritually on the eighth day of life, UTI occurred within 9 days of the circumcision. For females, there was no such clustering of UTI cases in the second week of life, nor during any other time period.

Conclusions: Febrile male neonates who have undergone ritual circumcision have a high prevalence of UTI and must be evaluated and treated accordingly.

Objectives: To define the incidence of congenital CMV infection in two different subpopulations, as a model for the entire population of Israel.

Methods: Urine specimens were randomly collected from 2,000 newborns in Shaare Zedek Medical Center, Jerusalem, and HaEmek Medical Center, Afula (1,000 specimens each). These hospitals have many characteristic differences, presumably representing the diverse population of Israel. Urine specimens were subjected to a CMV PCR[2] reaction and positive specimens were validated by urine viral culture. Maternal seroprevalence was determined in a representative sample of the mothers in each hospital. Epidemiologic characteristics of the mothers were extracted from hospital records and compared.

Results: The population in Shaare Zedek Medical Center was mostly Jewish (95.8%) and urban (87.0%), as compared to that of HaEmek Medical Center (49.2% and 61.0%, respectively, P < 0.01). Nevertheless, CMV seroprevalence was similar: 81.5% and 85%, respectively. Ten (1.0%) and 4 (0.4%) newborns, respectively, were found to have congenital CMV infection (not significant).

Conclusions: The combined incidence of congenital CMV infection in the study population was 0.7% (95% confidence interval 0.3–1.0%). If this rate is extrapolated to the entire population of Israel, then a total of 945 cases of congenital CMV can be expected among the 135,000 annual deliveries. A nationwide screening program for congenital CMV should be considered.

Background: Nasal colonization with methicillin-resistant Staphylococcus aureus in the community is being increasingly reported, but there is a general lack of data on MRSA[1] colonization in children in chronic care institutions and on colonization rates in Israeli children.

Objectives: To define the rate of MRSA nasal colonization in a generally healthy pediatric population in Jerusalem, to compare it with that of children in chronic care institutions, to define risk factors for colonization, and to compare community and hospital-acquired MRSA strains.

Methods: Anterior nares culture for the presence of methicillin-sensitive and methicillin-resistant S. aureus was taken from 831 healthy children attending primary pediatric clinics or emergency department and 118 children hospitalized in three chronic care institutions in Jerusalem.

Results: Of the 831 healthy children, 195 (23.5%) were colonized with S. aureus, as compared to 43 of 118 (36.4%) chronically institutionalized children (P < 0.005). Five of the 195 S. aureus isolates from healthy children (2.6%) were MRSA, as compared to 9 of 43 (21%) from chronically institutionalized children (P < 0.001). Older age and a family member who is a healthcare worker were associated with S. aureus colonization in the population of healthy children, and older age was associated with MRSA colonization in the chronically institutionalized children. The antibiotic susceptibility pattern was similar for both groups, and pulsed field gel electrophoresis of the isolates showed a wide and random distribution in both groups.

Conclusions: MRSA colonization in the studied pediatric community in Jerusalem was very low, whereas that of patients hospitalized in chronic care institutions was significantly higher. In the small number of isolates detected, no significant differences were found in antibiotic susceptibility or PFGE[2] pattern between hospital-acquired and community-acquired strains.

Background: Cefuroxime is a second-generation cephalosporin antibiotic used widely for the treatment of various infections.

Objectives: To assess the appropriateness of cefuroxime usage as well as the long-term impact of re-feeding the results to prescribing physicians.

Methods: Drug utilization evaluation involved three data-collecting periods, each comprising 6 weeks, during which all patients receiving cefuroxime were evaluated. Results of phase I were distributed to all physicians in a newsletter and departmental lectures; phase II was announced and conducted 6 months later. An identical phase III was unannounced and conducted one year after phase II. The study included all patients receiving cefuroxime during the three phases. The main outcome measure was appropriateness of initiation, and continuation beyond 3 days, of empirical treatment. Appropriateness was determined according to a prepared list of indications based on the literature and the hospital's protocols.

Results: Cefuroxime was initiated appropriately in 104 of 134 patients (78%) in phase I, in 85 of 100 (85%) in phase II, and in 93 of 100 (93%) in phase III (P<0.001). Cefuroxime was continued appropriately after 3 days in 58/134 (43%), 57/100 (57%) and 70/100 (70%) respectively (P<0.001). The total number of appropriate treatment days out of all treatment days increased from 516 of 635 (81%) in phase I, to 450 of 510 (88%) in phase II, to 485 of 509 (95%) in phase III (P<0.001). The principal reason for cefuroxime usage was community-acquired respiratory tract infection.

Conclusion: Drug utilization evaluation may provide valuable data on the usage of a particular drug. This information, once re-fed to physicians, may improve utilization of the particular drug. This positive effect may be prolonged beyond the immediate period of observation.
