Neonatal Risk Factors for Colonization with Extended-Spectrum Beta-Lactamase-Producing Bacteria in the Neonatal Intensive Care Unit.

BACKGROUND: Extended-spectrum beta-lactamase (ESBL) production is the most common antimicrobial resistance mechanism in the neonatal intensive care unit (NICU), with colonization and blood stream infections being a major threat to this population. Since 2013, all NICU admissions at our facility were screened twice weekly for ESBL colonization. OBJECTIVES: To determine independent risk factors for colonization of infants with ESBL-producing bacteria in the NICU. METHODS: A retrospective case study of ESBL-colonized infants vs. controls (matched by date of birth and gestational age) was conducted in the NICU of Soroka University Medical Center, Israel, between 2013 and 2014. Epidemiological, laboratory, and clinical data were extracted from medical files. Univariable and multivariable analyses were used to assess associations between ESBL colonization and possible clinical risk factors. RESULTS: Of 639 admissions during the study period, 87 were found to be ESBL-colonized (case infants) and were matched to 87 controls. Five case infants became infected (5.7%) with ESBL strains. Klebsiella pneumoniae was the most common isolated bacteria. The mean time from admission to colonization was 15 days. Univariable analysis showed an association of male gender and highest Apgar score at 1 and 5 minutes with ESBL colonization (P < 0.05). Multivariable analysis yielded only a possible association of higher Apgar score at 1 and 5 minutes (hazard ratio [HR] 1.515, 95% confidence interval [95%CI] 0.993-2.314; HR 1.603, 95%CI 0.958-2.682, respectively) with ESBL colonization. CONCLUSIONS: Future studies should focus on maternal colonization and possible strategies for preventing vertical transmission of ESBL strains to high-risk neonates.

Epidemiologic, clinical, laboratory, and therapeutic characteristics of influenza A/H1N1 in Moslem Bedouin and Jewish children hospitalized in southern Israel during 2009.

A total of 739 (225 H1N1(+)) children with a diagnosis of acute respiratory infection were hospitalized during July to December 2009. The H1N1(+) children were compared with 225 randomly enrolled H1N1(-) children with an influenza-like illness. As compared with influenza-like illness patients, patients with 2009 influenza A/H1N1 were characterized by older age, more vomiting, less hypoxemia and wheezing, lower white blood cell counts, less neutrophilia, and severe lymphopenia.

The prevalence of human papillomavirus and cervical cytology abnormalities in women infected with human immunodeficiency virus in southern Israel.

BACKGROUND: Concomitant human immunodeficiency virus (HIV) and human papillomavirus (HPV) infection increases both HPV persistence and the risk of invasive cervical cancer. An estimation of HPV prevalence among HIV-positive women in Israel would contribute to improving care for this population and preventing morbidity and mortality related to cervical cancer. OBJECTIVES: To determine the prevalence of HPV infection and cervical cytology abnormalities, and to assess the possible influence of HIV infection on HPV carriage in HIV-positive women attending the Infectious Disease Clinic at Soroka University Medical Center. METHODS: The study population included 84 HIV-seropositive women. They were examined by a gynecologist and screened for HPV genotyping, and Pap smears were obtained for cervical cytology. Demographic, behavioral, and HIV infection variables were also recorded and analyzed. RESULTS: Forty-nine (58.3%) of the study participants were HPV-positive; 34 of them had oncogenic genotypes. Young age (< 16 years) at first sexual intercourse was the only variable significantly associated with HPV infection (P < 0.05). Abnormal cervical cytology was present in 17 women (20.3%); 21 women were referred to colposcopy, which was abnormal in 9 (10.7%). CONCLUSIONS: The prevalence of HPV carriage among HIV-positive woman in our study was slightly higher than published elsewhere. The prevalence of pathological cervical cytology was much higher than in the general population. An extremely high prevalence of pathological colposcopies requiring further treatment was found. Screening for HPV and premalignant changes in the uterine cervix is highly recommended in the HIV-seropositive population. We suggest that colposcopy be considered part of the routine workup in HIV-seropositive woman.

Terlipressin facilitates transport of septic patients treated with norepinephrine.

BACKGROUND: Transport of hemodynamic unstable septic patients for diagnostic or therapeutic interventions outside the intensive care unit is complex but sometimes contributes to increasing the chance of survival. OBJECTIVES: To report our experience with terlipressin treatment for facilitation of transport to distant facilities for diagnostic or therapeutic procedures in septic patients treated with norepinephrine. METHODS: We conducted a retrospective analysis of the records of our ICU, identifying the patients with septic shock who required norepinephrine for hemodynamic support. RESULTS: Terlipressin was given to 30 septic shock patients (15 females and 15 males) who were on high dose norepinephrine (10 microg/min or more) in order to facilitate their transport outside the ICU. The dose of terlipressin ranged from 1 to 4 mg, with a mean of 2.13+/-0.68 mg. The dose of norepinephrine needed to maintain systolic blood pressure above 100 mmHg decreased following terlipressin administration, from 21.9+/-10.4 microg/min (range 5-52 microg/min) to 1.0+/-1.95 (range 0-10) (P < 0.001). No patients required norepinephrine dose adjustment during transport. No serious complications or overshoot in blood pressure values were observed following terlipressin administration. Acrocyanosis occurred only in eight patients receiving more than 1 mg of the drug. The overall mortality rate was 50%. CONCLUSIONS: Our data suggest that terlipressin is effective in septic shock. Because it is long-acting and necessitates less titration it might be indicated for patient transportation.
