Objectives: To evaluate health utilization patterns in two primary care clinics in southern Israel: one under continuous attacks of Qassam rockets as compared with a similar clinic not under a rocket threat.

Methods: We conducted a retrospective cross-sectional study in two primary care clinics in southern Israel, with 11,630 persons listed in the two clinics during the entire study period. The primary outcome measures were total annual number of visits per person to the clinic and for specific diagnoses, and the number of drug prescriptions issued, emergency room (ER) visits, hospitalization days, cardiac catheterizations and coronary bypass surgeries.

Results: In both clinics there was an increase over time in the mean annual number of visits per person. During the years of severe attacks there was an increase in visits with a chief complaint of depression and anxiety and an increase in the number of anxiolytic prescriptions in the study clinic compared with the control. During the same period there was a decrease in the number of ER visits in the study clinic compared with the control.

Conclusions: The population under continuous life-threatening events showed more depression and anxiety problems. Under severe bombardment, the residents prefer not to leave home, unless necessary.

Objectives: To evaluate the clinical course of four children with cricopharyngeal achalasia presenting to our clinic.

Methods: We conducted a 5 year retrospective chart review in a tertiary referral center.

Results: Four children were diagnosed with primary cricopharyngeal achalasia between 2006 and 2010. Diagnosis was established by videofluoroscopy and all underwent uneventful cricopharyngeal myotomy. Three children recovered completely and one child showed partial improvement. For residual UES spasm in a partially improved patient, botulinum toxin was injected into the UES which led to further improvement. Dysphagia recurred in one child who was successfully treated with botulinum toxin injection.

Conclusions: Cricopharyngeal myotomy is a safe procedure in infants and young children. Botulinum toxin injection of the UES was found to be effective in refractory cases. 

Methods: We assessed 25 patients with insomnia who were enrolled in a hypnotic study but prior to the study were asked to undergo two full nights in lab polysomnography studies: with and without a placebo. Although they were not explicitly told that they were receiving a placebo, the participants knew that the results of these studies would determine whether they met the criteria to participate in the pharmaceutical study.

Results: Although the participants acknowledged that they were given a placebo, almost all measures of their sleep improved. With placebo, sleep latency was shortened from 55.8 ± 43.5 to 39.8 ± 58.5 minutes (P < 0.05); total sleep time was extended from 283 ± 72.5 to 362.9 ± 56.3 minutes, and sleep efficiency improved from 59.57 ± 14.78 to 75.5 ± 11.70% (P < 0.05). Interestingly, placebo had no effect on the relative sleep stage distribution (percentage of total sleep time), except for a trend toward increased percentage of REM[1] sleep.

Conclusions: Our findings how a clear and significant beneficial effect of placebo on insomnia, despite participants' understanding that they were receiving placebo. These results emphasize the importance of the patients' perception and belief in insomnia treatment, and suggest that in some cases placebo may serve as a treatment.

Objectives: To investigate current smoking trends among Israeli physicians.

Methods: All practicing physicians at a tertiary university-affiliated medical center in central Israel were invited to complete a Web-based questionnaire on smoking habits and smoking-related issues via the institutional email. Findings were compared to those in the general population and between subgroups.

Results: Of the 90 responders (53 male, 88 Jewish), 54 (60%) had never smoked, 21 (23.3%) were past smokers, and 15 (16.7%) were current smokers. The rate of current smokers was lower than in the general population. The proportion of current smokers was higher among residents than attending physicians and among physicians in surgical compared to medical specialties. Past smokers accounted for 17.9% of the residents (average age at quitting 26.2 years) and 28.1% of the attending physicians (average age at quitting 33.0 years). Non-smokers more frequently supported harsh anti-smoking legislation.

Conclusions: The rate of smoking is lower in physicians than in the general population but has not changed over the last 15 years. Anti-smoking programs should particularly target physicians in surgical specialties. 

Objectives: To compare the incidence rate of overall and site-specific cancers among Israeli Arabs with T2DM to that of Israeli Arabs without.

Methods: A retrospective cohort study of all adult Arab members of Clalit Healthcare Services in northern Israel was conducted over a 10 year period (1999–2008).

Results: During the study period 752 and 2045 incident cases of cancer were diagnosed among 13,450 adults with diabetes and 74,484 without, respectively. The follow-up time involved 817,506 person-years. Diabetes was associated with a standard incidence ratio (SIR) of 3.27 (95%CI 1.49–5.05) and 2.87 (95%CI 1.25–4.50) for pancreatic cancer in men and women, respectively. A significantly reduced SIR (0.67, 95%CI 0.36–0.99) was observed for esophageal, stomach and intestinal cancers in men.

Conclusions: Our findings support an association between T2DM and increased risk of cancer of the pancreas in Arab men and women. A significantly reduced risk of all other cancers was observed only in Arab men. Our findings underscore the need for effective diabetes and cancer prevention and intervention programs. 

Background: The number of patients treated with intravitreal injections has increased significantly over the past few years, mainly following the introduction of anti-vascular endothelial growth factor antibody intraocular medications. Bevacizumab is mostly used in this group of medications.

Objectives: To describe persistent elevation of intraocular pressure (IOP) following intravitreal injection of bevacizumab.

Methods: We reviewed consecutive cases of persistent IOP elevation after intravitreal bevacizumab injection for exudative age-related macular degeneration (AMD). A total of 424 patients (528 eyes) met the inclusion criteria and received 1796 intravitreal injections of bevacizumab. Persistent IOP elevation was found in 19 eyes (3.6%, 19/528) of 18 patients (4.2%, 18/424) with IOP elevated 30–70 mmHg, 3–30 days after injection.

Results: Mean IOP was 42.6 mmHg (range 30–70); IOP elevations occurred after an average of 7.8 injections of bevacizumab (range 3–13). Injected eyes (19/528) had a significantly higher incidence of elevated IOP than uninjected eyes (fellow eyes), 1/328, P < 0.001.

 Conclusions: Like other anti-vascular endothelial growth factor (VEGF) substances reported in a few recent studies, intravitreal injection of bevacizumab for neovascular AMD may be associated with persistent IOP elevation. Providers should be aware that significant IOP elevation might occur after repeated treatments. 

Objectives: To devise a protocol to reduce the loss of pathology specimens.

Methods: In this study, 7105 specimens excised by one plastic surgeon were sent to the pathology laboratory using a strict protocol, which included: using a carefully labeled specimen container, inserting the specimen into the container immediately after excision (not at the end of the procedure), positioning the specimen container close to the surgical field during the surgery, and both the nurse and surgeon signing their names on the container at the end of the procedure to confirm the contents and labeling.

Results: One Mohs specimen was accidentally thrown away by a pathology laboratory technician after the frozen section report was written (an incidence of 1/7105, 0.00014%). All specimens arrived in the pathology department and no lesions were lost in the operating room.

Conclusions: A strict written protocol for specimen handling significantly reduces loss of pathology specimens.

Objectives: To define preoperative predictors for MPC in prostatectomy specimens and to examine the accuracy of such prediction.

Methods: Data collected on 1526 consecutive radical prostatectomy patients operated in a single center between 2003 and 2008 included: age, body mass index, preoperative prostate-specific antigen level, biopsy Gleason score, clinical stage, percentage of positive biopsy cores, and maximal core length (MCL) involvement. MPC was defined as < 5% of prostate volume involvement with organ-confined Gleason score ≤ 6. Univariate and multivariate logistic regression analyses were used to define independent predictors of minimal disease. Classification and Regression Tree (CART) analysis was used to define cutoff values for the predictors and measure the accuracy of prediction.

Results: MPC was found in 241 patients (15.8%). Clinical stage, biopsy Gleason`s score, percent of positive biopsy cores, and maximal involved core length were associated with minimal disease (OR 0.42, 0.1, 0.92, and 0.9, respectively). Independent predictors of MPC included: biopsy Gleason score, percent of positive cores and MCL (OR 0.21, 095 and 0.95, respectively). CART showed that when the MCL exceeded 11.5%, the likelihood of MPC was 3.8%. ;Conversely, when applying the most favorable preoperative conditions (Gleason ≤ 6, < 20% positive cores, MCL ≤ 11.5%) the chance of minimal disease was 41%.

Conclusions: Biopsy Gleason score, the percent of positive cores and MCL are independently associated with MPC. While preoperative prediction of significant prostate cancer was accurate, clinical prediction of MPC was incorrect 59% of the time. Caution is necessary when implementing clinical data as selection criteria for active surveillance.
