Background: The role of routine active surveillance cultures (ASCs) in predicting consequent blood stream infections is unclear.

Objectives: To determine prospectively whether routine screening ASCs obtained on admission to the intensive care unit (ICU) can predict the causative agent of subsequent bloodstream infections.

Methods: We prospectively studied a cohort of 100 mechanically ventilated patients admitted consecutively to a 16-bed ICU. On admission, ASCs were obtained from four sites: skin cultures (swabs) from the axillary region, rectal swabs, nasal swabs, and deep tracheal aspirates. Thereafter, cultures were obtained from all four sites daily for the next 5 days of the ICU stay.

Results: Of the 100 recruited patients 31 (31%) had culture-proven bacteremia; the median time to development of bacteremia was 5 days (range 1–18). Patients with bacteremia had a longer median ICU stay than patients without bacteremia: 14 days (range 2–45) vs. 5 days (1–41) (P < 0.001). ICU and 28 day mortality were similar in patients with and without bacteremia. Most ASCs grew multiple organisms. However, there was no association between pathogens growing on ASCs and eventual development of bacteremia.

Conclusions: ASCs obtained on ICU admission did not identify the causative agents of most subsequent bacteremia events. Therefore, bloodstream infections could not be related to ASCs.

Background: Tinea pedis is a common chronic skin disease; the role of contaminated clothes as a possible source of infection or re-infection has not been fully understood. The ability of ultraviolet light to inactivate microorganisms has long been known and UV is used in many applications.

Objectives: To evaluate the effectivity of sun exposure in reducing fungal contamination in used clothes.

Methods: Fifty-two contaminated socks proven by fungal culture from patients with tinea pedis were studied. The samples were divided into two groups: group A underwent sun exposure for 3 consecutive days, while group B remained indoors. At the end of each day fungal cultures of the samples were performed.

Results: Overall, there was an increase in the percentage of negative cultures with time. The change was significantly higher in socks that were left in the sun (chi-square for linear trend = 37.449, P < 0.0001).

Background: A high prevalence of iron deficiency anemia persists in Bedouin Arab and Jewish pediatric populations in southern Israel.

Objectives: To compare the effect of daily use of multiple micronutrient supplementation (MMS), "Sprinkles," a powdered formulation of iron, vitamins A and C, folic acid and zinc, with liquid iron and vitamins A and D on iron deficiency at 12 months of age.

Methods: The 621 eligible Bedouin and Jewish infants in the study were assigned to the MMS and control arms and received their supplementations from age 6 to 12 months. We examined the change in hemoglobin, hematocrit, mean cell volume, red blood cell distribution, serum ferritin and transferrin saturation. In addition, we used the high Iron Deficiency Index (IDI) if two or more of the above six parameters showed abnormal levels. 

Results: Rates of anemia decreased significantly over the 6 month period, from 58.8% to 40.6% among Bedouin infants (P = 0.037) and from 40.6 to 15.8% among Jewish infants (P = 0.017). In Bedouin infants the prevalence of high IDI decreased significantly from 79.2% to 67.4% (P = 0.010) in the MMS group, but there was no change in the controls. Among Jewish infants, the high IDI prevalence decreased from 67% to 55.6% with no statistically significant difference in the two study arms. In the multivariate analysis in Bedouin infants MMS use was associated with a reduced risk of 67% in high IDI at age 12 months as compared to controls (P = 0.001). Fewer side effects in the intervention groups in both ethnic populations were reported.

Conclusions: MMS fortification of home food can be recommended as an effective and safe method for preventing iron deficiency anemia at 12 months of age.

Background: Over the past 20 years, advances in endoscopic sinus surgery (ESS) techniques have led to widespread applications of this technology in both adult and pediatric populations with better results and lower morbidity.

Objectives: To update data regarding the rate of minor and major complications following ESS procedures that used powered instrumentation.

Methods: We retrospectively reviewed the charts of all patients who, with general anesthesia, underwent ESS utilizing powered instrumentation between January 1996 and December 2006. Age, gender, indication for surgery, length of hospitalization, and type and rate of surgical complications were recorded.

Results: A total of 1190 patients were included in our study (1309 surgeries). The male:female ratio was 1.7:1.0 and the average age was 39 years (range 4–86 years). The most common indication for surgery was chronic rhinosinusitis. The rate of major complications was 0.31% and that of minor complications 1.37%. The only major complication that occurred was cerebrospinal fluid leak. The minor complications included epistaxis, periorbital emphysema, ecchymosis and mucocele formation.

Conclusions: Compared to previously published series, the rate of major and minor complications in our study was low. The results indicate that the use of powered instruments during ESS is safe.

Background: The VEGFR/PDGFR inhibitor sunitinib was approved in Israel in 2008 for the treatment of metastatic renal cell carcinoma (mRCC), based on an international trial. However, the efficacy of sunitinib treatment in Israeli mRCC patients has not been previously reported.

Objectives: To report the outcome and associated factors of sunitinib treatment in a large cohort of Israeli mRCC patients.

Methods: We conducted a retrospective study of an unselected cohort of mRCC patients who were treated with sunitinib during the period 2006–2013 in six Israeli hospitals. Univariate and multivariate analyses were performed to determine the association between treatment outcome and clinicopathologic factors.

Results: We identified 145 patients; the median age was 65 years, 63% were male, 80% had a nephrectomy, and 28% had prior systemic treatment. Seventy-nine percent (n=115) had clinical benefit (complete response 5%, n=7; partial response 33%, n= 48; stable disease 41%, n=60); 21% (n=30) were refractory to treatment. Median progression-free survival (PFS) was 12 months and median overall survival 21 months. Factors associated with clinical benefit were sunitinib-induced hypertension: [odds ratio (OR) 3.6, P = 0.042] and sunitinib dose reduction or treatment interruption (OR 2.4, P = 0.049). Factors associated with PFS were female gender [hazard ratio (HR) 2, P = 0.004], pre-sunitinib treatment neutrophil to lymphocyte ratio ≤ 3 (HR 2.19, P = 0.002), and active smoking (HR 0.19, P < 0.0001). Factors associated with overall survival were active smoking (HR 0.25, P < 0.0001) and sunitinib-induced hypertension (HR 0.48, P = 0.005). To minimize toxicity, the dose was reduced or the treatment interrupted in 39% (n=57). 

Conclusions: The efficacy of sunitinib treatment for mRCC among Israeli patients is similar to that of international data.

 Background: Modifications to conventional laparoscopic cholecystectomy (CLC) are aimed at decreasing abdominal wall trauma and improving cosmetic outcome. Although single-incision laparoscopic surgery (SILS) provides excellent cosmetic results, the procedure is technically challenging and expensive compared to the conventional laparoscopic approach.

Objectives: To describe a novel, hybrid technique combining SILS and conventional laparoscopy using minimal abdominal wall incisions.

Methods: Fifty patients diagnosed with symptomatic cholelithiasis were operated using two reusable 5 mm trocars inserted through a single 15 mm umbilical incision and a single 2–3 mm epigastric port. This technique was dubbed “minimal incision laparoscopic cholecystectomy” (MILC).

Results: MILC was completed in 49 patients (98%). In five patients an additional 3 mm trocar was used and in 2 patients the epigastric trocar was switched to a 5 mm trocar. The procedure was converted to CLC in one patient. Mean operative time was 29 minutes (range 18–60) and the average postoperative hospital stay was 22 hours (range 6–50). There were no postoperative complications and the cosmetic results were rated excellent by the patients.

Conclusions: MILC is an intuitive, easy-to-learn and reproducible technique and requires small changes from CLC. As such, MILC may be an attractive alternative, avoiding the cost and complexity drawbacks associated with SILS.

Background: A growing number of Eritrean and Sudanese refugees seek medical assistance in the labor and delivery ward of our facility. Providing treatment to this unique population is challenging since communication is limited and pregnancy follow-up is usually absent.

Objectives: To compare the perinatal outcome of refugees and Israeli parturients.

Methods: The medical and financial records of all refugees delivered between May 2010 and April 2011 were reviewed. Perinatal outcome was compared to that of native Israeli controls.

Results: During this period 254 refugees were delivered (2.3% of deliveries). Refugees were significantly younger and leaner. They had significantly more premature deliveries under 37 weeks (23 vs. 10, P = 0.029) and under 34 weeks gestation (9 vs. 2, P = 0.036) with more admissions to the neonatal intensive care unit (15 vs. 5, P = 0.038). Overall cesarean section rate was similar but refugees required significantly more urgent surgeries (97% vs. 53%, P = 0.0001). Refugees had significantly more cases of meconium and episiotomies but fewer cases of epidural analgesia. There were 2 intrauterine fetal deaths among refugees, compared to 13 of 11,239 deliveries during this time period (P = 0.036), as well as 7 pregnancy terminations following sexual assault during their escape. Sixty-eight percent of refugees had medical fees outstanding with a total debt of 2,656,000 shekels (US$ 767,250).

Conclusions: The phenomenon of African refugees giving birth in our center is of unprecedented magnitude and bears significant medical and ethical implications. Refugees proved susceptible to adverse perinatal outcomes compared to their Israeli counterparts. Setting a pregnancy follow-up plan could, in the long run, prevent adverse outcomes and reduce costs involved in treating this population.

Background: Prescription errors are common in hospitalized patients and result in significant morbidity, mortality and costs. Electronic prescriptions with computerized physician order entry systems (CPOE) and integrated computerized decision support systems (CDSS providing online alerts) reduce prescription errors by approximately 50%. However, the introduction of CDSS is often met by opposition due to the flood of alerts, and most prescribers eventually ignore even crucial alerts (“alert fatigue”). 

Objectives: To describe the implementation and customization of a commercial CDSS (SafeRx®) for electronic prescribing in Internal Medicine departments at a tertiary care center, with the purpose of improving comprehensibility and substantially reducing the number of alerts to minimize alert fatigue. 

Methods: A multidisciplinary expert committee was authorized by the hospital administration to customize the CDSS according to the needs of six internal medicine departments at Sheba Medical Center. We assessed volume of prescriptions and alert types during the period February–August 2012 using the statistical functions provided by the CDSS. 

Results: A mean of 339 ± 13 patients per month per department received 11.2 ± 0.5 prescriptions per patient, 30.1% of which triggered one or more CDSS alerts, most commonly drug-drug interactions (43.2%) and dosing alerts (38.3%). The review committee silenced or modified 3981 alerts, enhancing comprehensibility, and providing dosing instructions adjusted to the patient’s renal function and recommendations for follow-up. 

Conclusions: The large volume of drug prescriptions in internal medicine departments is associated with a significant rate of potential prescription errors. To ensure its effectiveness and minimize alert fatigue, continuous customization of the CDSS to the specific needs of particular departments is required.
