Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and methicillin-resistant Staphylococcus aureus and Candida species).
Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.
Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members.
Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.
Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible.

Background: Two types of growth curves are commonly used to diagnose fetal growth disorders: neonatal birth weight (BW) and sonographic estimated fetal weight (EFW). The debate as to which growth curve to use is universal.
Objectives: To establish sonographic EFW growth curves for the Israeli population and to assess whether the use of the BW growth curves currently adapted in Israel leads to under-diagnosis of intrauterine growth disorders.
Methods: Biometric data collected during a 6 year period was analyzed to establish sonographic EFW growth curves between 15–42 weeks of gestation for the Israeli population. Growth curves were compared to previously published sonographic EFW growth curves. A comparison with the Israeli BW growth curves was performed to assess the possibility of under-diagnosis of intrauterine growth disorders.
Results: Out of 42,778 sonographic EFW studies, 31,559 met the inclusion criteria. The sonographic EFW growth curves from the current study resembled the EFW curves previously published. The comparison of the current sonographic EFW and BW growth curves revealed under-diagnosis of intrauterine growth disorders during the preterm period. Four percent of the fetuses assessed between 26–34 weeks would have been suspected of being growth restricted; 2.8 percent of the fetuses assessed between 30–36 weeks would have been suspected of having macrosomia, based on the BW growth curves.
Conclusions: New Israeli sonographic EFW growth curves resemble previously published sonographic EFW curves. Using BW growth curves may lead to the under-diagnosis of growth disorders. We recommend adopting sonographic EFW growth to diagnose intrauterine growth disorders.

Background: Preterm birth is the leading cause of morbidity and mortality among neonates in the United States. Early recognition of sepsis in this population is a challenging task since overt clinical signs can be difficult to determine. C-reactive protein (CRP), one of the most frequently non-specific used laboratory test, can indirectly aid the diagnosis of neonatal sepsis.
Objectives: To evaluate the relationship between histological findings in the placenta of preterm newborns born after prolonged rupture of membranes, CRP levels, and blood cultures.
Methods: Medical records were reviewed of all preterm newborns born after prolonged premature rupture of membranes at a medical center in Israel between 2011 and 2014.
Results: Of 128 newborns with prolonged rupture of membranes, 64 had evidence of histological chorioamnionitis (HCA). Gestational age, birth weight, and Apgar scores were significantly lower, while CRP levels (on admission and 10–12 hours post-delivery) were significantly higher in preterm newborns born to mothers with histological evidence of chorioamnionitis, but values were within normal ranges. Duration of the rupture of membranes and white blood cell counts did not differ between groups.
Conclusions: CRP levels taken on admission and 10–12 hours after delivery were higher when HCA was present, but since there was a substantial overlap between those with and without HCA and the values for most were within normal range, the differences were not enough to serve as a tool to diagnose placental histological chorioamnionitis in preterm infants born after prolonged premature rupture of membranes and exposed to intrapartum antibiotics.

Background: Neoadjuvant chemo-radiation therapy (CRT) dosages in locally advanced non-small cell lung cancer (NSCLC) were traditionally limited to 45 Gray (Gy).
Objectives: To retrospectively analyze outcomes of patients treated with 60 Gy CRT followed by surgery.
Methods: A retrospective chart review identified patients selected for CRT to 60 Gy followed by surgery between August 2012 and April 2016. Selection for surgery was based on the extent of disease, cardiopulmonary function, and response to treatment. Pathological response after neoadjuvant CRT was scored using the modified tumor regression grading. Local control (LC), disease free survival (DFS), and overall survival (OS) were estimated by the Kaplan–Meier method.
Results: Our cohort included 52 patients: 75% (39/52) were stage IIIA. A radiation dose of 60 Gy (range 50–62Gy) was delivered in 82.7%. Surgeries performed included: lobectomy, chest-wall resection, and pneumonectomy in 67.3%, 13.4%, and 19.2%, respectively. At median follow-up of 22.4 months, the 3 year OS was 74% (95% confidence interval [CI] 52–87%), LC was 84% (95%CI 65–93), and DFS 35% (95%CI 14–59). Grade 4–5 postoperative complications were observed in 17.3% of cases and included chest wall necrosis (5.7%), bronco-pleural fistula (7.7%), and death (3.8%). A major pathologic regression with < 10% residual tumor occurred in 68.7% of patients (36/52) and showed a trend to improved OS (P = 0.1). Pneumonectomy cases had statistically worse OS (P = 0.01).
Conclusions: Major pathologic regression was observed 68.7% with 60 Gy neoadjuvant CRT with a trend to improved survival. Pneumonectomy correlated with worse survival.

Background: Medication reconciliation (MR) at hospital admission, transfer, and discharge has been designated as a required hospital practice to reduce adverse drug events.
Objectives: To perform MR among elderly patients admitted to the hospital and to determine factors that influence differences between the various lists of prescribed drugs as well as their actual consumption.
Methods: We studied patients aged 65 years and older who had been admitted to the hospital and were taking at least one prescription drug.
Results: The medication evaluation and recording was performed within 24 hours of admission (94%). The mean number of medications was 7.8 per patients, 86% consumed 5 or more medications. Mismatching between medication prescribed by a primary care physician (PCP) and by real medication use (RMU) was found in 82% of patients. In PCP the most common mismatched medications were cardiovascular drugs (39%) followed by those affecting the alimentary tract, metabolism (24%), and the nervous (12%) system. In RMU, the most commonly mismatched medications were those affecting the alimentary tract and metabolism (36%). Among all causes of mismatched medications, discrepancies in one drug were found in 67%, in two drugs in 21%, and in three drugs in 13%. The mismatching was more common in females (85%) than in males (46%, P = 0.042).
Conclusions: This study provided evidence in a small sample of patients on differences of drug prescription and their use on admission and on discharge from hospital. MR processes have a high potential to identify clinically important discrepancies for all patients.

Background: Several studies have addressed the issue of undetected uterine pathology in women undergoing hysterectomy for pelvic organ prolapse (POP). However, these studies differ largely with respect to the incidence of malignancy found, study population, and preoperative evaluation.
Objectives: To assess the risk of unexpected pre-malignant and malignant uterine pathological findings after vaginal hysterectomy for POP repair, in a single medical center in Israel.
Methods: A retrospective study was performed of all patients who underwent vaginal hysterectomy due to symptomatic POP between January 1990 and April 2015 in a single tertiary medical center. Selected clinical and pathological data were retrieved from the computerized medical records. All specimens were routinely sent for histopathological assessment. All women were managed according to a uniform protocol that required the presence of a preoperative normal Pap smear, and included preoperative transvaginal sonography and endometrial biopsy when indicated. Patients in whom premalignant or malignant lesions were found preoperatively were not included in the study.
Results: The study comprised 667 patients. The overall rate of malignant or significant premalignant pathologies (6 cases) was 0.89%, including one (0.14%) case of endometrial carcinoma. All premalignant and malignant pathologies were found only in post-menopausal patients. The rate of significant endometrial pathological lesions found in asymptomatic post-menopausal women was only 0.35%.
Conclusions: The rate of preoperatively undetected abnormal histopathological findings in patients who undergo vaginal hysterectomy due to POP is very low, and therefore more extensive preoperative evaluation is not warranted in them.

Background: Invasive cervical cancer is caused by human papillomavirus (HPV).
Objectives: To describe the prevalence and genotype distribution of HPV types in women at risk for cervical neoplasia.
Methods: Our study summarized HPV types detected in 6654 samples that were sent to the serology laboratory from cervical clinics in northern Israel between 2006–2014. The HPV test was performed during investigation of atypical squamous cells of undetermined significance (ASCUS) results on Pap tests or due to complaints suggestive of cervical neoplasia. HPV types were classified as high risk (HPV-HR) and low risk (HPV-LR).
Results: Of the samples, 46.4% (3085/6654) were HPV-HR positive. Of women with cervical intraepithelial neoplasia 2-3 (CIN 2-3) or cancer, 292/318 (91.8%) and 137/145 (94.5%), respectively, were HPV-HR positive. HPV 16 and HPV 18 were detected in 11.8% of the total samples and in 48.2% and 64.9% of the women with CIN 2-3 and with cancer, respectively. HPV was negative in 8/145 (5.5%) and 26/318 (8.2%) of women with cervical cancer and CIN 2-3, respectively.
Conclusions: This study shows the prevalence of HPV types in women at risk for cervical neoplasia. The sensitivity of all HPV types for CIN 2-3 and cervical cancer was 91.8% and 94.5%, respectively; and of HPV-HR types, 89% and 92.4%, respectively. Triage of HPV-HR types should be considered in women with ASCUS because HPV-HR types were discovered in only 36.7%. The distribution of HPV types in our population is similar to that reported for other developed countries.
