Background: The fish-eating habits of Israelis who present with impacted fish bones in the aerodigestive tract are unknown.

Objectives: To retrospectively investigate the relation between an impacted fish bone in the aerodigestive tract, the species of fish, and the place of occurrence in an Israeli population.

Methods: The current prospective observational study included all patients with aerodigestive impacted fish bones who were treated in our emergency department from 1 September 2008 to 30 September 2009. The data retrieved from their medical records included age, gender, place of event (at home or elsewhere), species of fish, and method of removing the bone.

Results: A total of 108 patients aged 1.5–87 years (median 48 years), 52.8% female, met the study criteria. Most (87%) of the events occurred at home, and 50.9% occurred during the weekend (Friday- Saturday). The bones were from low-priced fish (e.g., carp, hake) in 62% of the cases, high-priced fish (e.g., salmon, red snapper) in 30.5%, and of unknown species in 10.2%. The proportion of cases in which the fish bone belonged to a high-priced fish eaten out of the home was significantly higher than the cases in which a low-priced fish was eaten at home (64.3% vs. 22.3%, P = 0.04). One hundred bones were removed during direct oral inspection and 8 bones were removed under general anesthesia by endoscopy.

Conclusions: Most fish bone impactions in the aerodigestive tract in central Israel involve low-priced fish and take place at home over the weekend.
 

Background: The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life.

Objectives: To present the feasibility, reliability, and validity of the Hebrew version of the EQ-5D[1].

Methods: We conducted face-to-face interviews with a representative sample (n=1666) of the Israeli Jewish population. The data collected included demographic and medical information, and self-valuation of health using the EQ-5D descriptive system, Visual Analogue Scale and Time Trade-Off. Construct validity was assessed by assuming that older individuals, those with a greater burden of diseases, and those reporting experience with their own severe illness would have lower EQ-5D indexes, VAS[2] and TTO[3] values. Test-retest reliability was assessed in a small sample (n=50) that was reevaluated after a 3 week interval.

Results: Test-retest reliability of the EQ-5D and VAS was very high (r ≥ 0.85). Reliability of the TTO was moderate (r = 0.48). There were significant differences in the EQ-5D index, profiles, VAS and TTO between healthy and sick respondents and younger and older respondents, indicating good validity of the instrument.

Conclusions: The Hebrew translation of the EQ-5D is a practical, reliable and valid instrument for assessing the health-related quality of life of the general Israeli Jewish population.

Background: Coronary CT angiography is an accurate imaging modality; however, its main drawback is the radiation dose. A new technology, the "step and shoot," which reduces the radiation up to one-eighth, is now available.

Objectives: To assess our initial experience using the "step-and-shoot" technology for various vascular pathologies.

Methods: During a 10 month period 125 consecutive asymptomatic patients (111 men and 14 women aged 25–82, average age 54.9 years) with various clinical indications that were appropriate for step-and-shoot CCTA[1] (regular heart rate < 65 beats/minute and body weight < 115 kg) were scanned with a 64-slice multidetector computed tomography Brilliance scanner (Philips, USA). The preparation protocol for the scan was the same as for the regular coronary CTA. All examinations were interpreted by at least one experienced radiologist and one experienced interventional cardiologist. The quality of the examinations was graded from 1 (excellent imaging quality of all coronary segments) to 4 (poor quality, not diagnostic). There were 99 patients without a history of coronary intervention, 13 after coronary stent deployment (19 stents), and 3 after coronary artery bypass graft.

Results: Coronary interpretation was obtained in 122 examinations (97.6%). The imaging quality obtained was as follows: 103 patients scored 1 (82.4%), 15 scored 2 (12%), 4 scored 3 (3.2%) and 3 scored 4 (2.4%). The grades were unrelated to cardiac history or type of previous examinations. Poor image quality occurred because of sudden heart rate acceleration during the scan (one patient), movement and respiration (one patient), and arrhythmia and bad scan timing (in one). Two patients were referred to percutaneous coronary intervention based on the CCTA findings, which correlated perfectly.

Conclusions: Step-and-shoot CCTA is a reliable technique and CCTA algorithm comparable to the regular CCTA. This technique requires the lowest radiation dose, as compared to other coronary imaging modalities, that can be used for all CCTA indications based on the inclusion criteria of low (> 65 bpm) and stable heart rate.

Background: The criteria for tonsillectomy for recurrent tonsillitis were established by prospective studies in the pediatric population and are applied to adults as well. No studies have been conducted to assess whether these guidelines are followed. 

Objectives: To examine the eligibility for tonsillectomy of tonsillectomized patients who were referred because of recurrent acute tonsillitis.

Methods: A retrospective case series in an ambulatory military otolaryngology clinic was conducted, and the medical records of 44 tonsillectomized patients who suffered from throat infections in the year before surgery were analyzed. The number of tonsillar infections that met the referral criteria was counted.

Results: The average number of throat infections that met the referral criteria was 1.89 per year. The average number of visits to the clinic due to upper respiratory tract infection was 12.92 (range 2–36) per year. The average number of visits for any cause was 45.13 (range 6–64) per year. One patient with eight documented throat infections met the criteria of more than six infections in the last year.

Conclusion: Although the referral criteria were not strictly met, we speculate that surgery was probably beneficial. This study shows that the indications for tonsillectomy referral are not strictly followed, and that new criteria for referral of adults for tonsillectomy need to be established.

Background: On-site cardiac surgery is not widely available in developing countries despite a high prevalence of coronary artery disease.

Objectives: To analyze the safety, feasibility and cost-effectiveness of transradial percutaneous coronary intervention without on-site cardiac surgery in a community hospital in a developing country.

Methods: Of the 174 patients who underwent PCI[1] for the first time in our center, we analyzed two groups: stable coronary disease and acute myocardial infarction. The primary endpoint was the rate of complications during the first 24 hours after PCI. We also analyzed the length of hospital stay and the rate of hospital readmission in the first week after PCI, and compared costs between the radial and femoral approaches.

Results: The study group comprised 131 patients with stable coronary disease and 43 with acute MI[2]. Among the patients with stable coronary disease 8 (6.1%) had pulse loss, 12 (9.16%) had on-site hematoma, and 3 (2.29%) had bleeding at the site of the puncture. Among the patients with acute MI, 3 (6.98) had pulse loss and 5 (11.63%) had bleeding at the site of the puncture. There were no cases of atriovenous fistula or nerve damage. In the stable coronary disease group, 130 patients (99%) were discharged on the same day (2.4 ± 2 hours). In the acute MI group, the length of stay was 6.6 ± 2.5 days with at least 24 hours in the intensive care unit. There were no hospital readmissions in the first week after the procedure. The total cost, which includes equipment related to the specific approach and recovery room stay, was significantly lower with the radial approach compared to the femoral approach (US$ 500 saving per intervention).

Conclusions: The transradial approach was safe and feasible in a community hospital in a developing country without on-site cardiac surgery backup. The radial artery approach is clearly more cost effective than the femoral approach.

Background: Previous pregnancies may influence the success of medical termination of pregnancy.

Objectives: To determine the effect of parity and gravidity on the successful termination of pregnancy using mifepristone and misoprostol.

Methods: The medical files of all patients attending a department of obstetrics and gynecology during the years 2006 and 2007 for the purpose of medical termination of pregnancy at ≤ 49 days of gestation were analyzed retrospectively. The medical history, previous pregnancies and deliveries were recorded. Mifepristone was administered orally followed by 400 mg of misoprostol 48 hours later. A second dose of misoprostol was offered 2 weeks later if uterine content thickness was more than 15 mm. Then, after 24 hours, if uterine content thickness was more than 15 mm the uterus was evacuated by dilation and curettage.

Results: Of 403 women, 349 (86.6%) aborted following the basic regime; 207 (51.4%) (group A) were primiparous while 196 (48.6%) (group B) had at least one prior pregnancy. Uterine curettage was performed in 17 patients (8.2%) in group A and in 37 (18.9%) in group B (P = 0.002). When patients with a history of a previous abortion were excluded from group B, 32 of 143 (22.4%) required curettage (P < 0.001). When patients without a history of previous cesarean section were excluded, 10 of 52 (19.2%) underwent curettage (P = 0.038).

Conclusions: Previous pregnancies negatively affect the success of medical termination of pregnancy, especially in women with a previous term pregnancy. This information is important when counseling women about the method of pregnancy termination.
 

The introduction of novel targeted therapies into the clinic in recent years has had a considerable impact on the management of several neoplastic diseases – such as gastrointestinal stromal tumors, hepatocellular carcinomas and renal cell carcinomas – considered until recently refractory to systemic therapies. We describe here two such novel biological agents, sunitinib and sorafenib, as a paradigm of the successful clinical application of new concepts. Sunitinib and sorafenib are small molecule tyrosine kinase inhibitors that target vascular endothelial growth factor receptor, platelet-derived growth factor receptor, C-Kit and others. Both agents are administered orally; sunitinib is typically given in cycles for 4 consecutive weeks with 2 weeks off, while sorafenib is given continually. Side effects occur in most patients, similar for both agents; they may affect several systems and organs but are mostly mild and easily manageable, rarely requiring discontinuation of the drug. However, these toxicities require prompt attention and intervention. The most frequently observed effects are hypertension, nausea, anorexia, asthenia and cutaneous manifestations; cardiac abnormalities may include congestive failure. Sunitinib, and markedly less frequently sorafenib, may cause thyroid gland dysfunction, mainly hypothyroidism. Antitumor activity has been shown for renal cell carcinoma in pivotal trials, for sunitinib as first-line treatment and for sorafenib in previously treated patients as second-line. Sunitinib is now approved as second-line therapy for patients with GIST[1] refractory to imatinib; sorafenib has resulted in a significant prolongation in median survival in patients with hepatocellular carcinoma. Ongoing clinical trials will further define the spectrum of these agents' antitumor activity, their role in combination with other drugs, as well as their optimal dose and schedule of administration.

Background: In compliance with public health measures initiated by the Israel Ministry of Health following an outbreak of influenza, amantadine was administered to all patients in the psychogeriatric department of Lev Hasharon Mental Health Center to reduce transmission and illness severity in this susceptible population.

Objectives: To evaluate the potential beneficial effects of amantadine on elderly hospitalized patients with persistent schizophrenia.

Methods: We conducted a retrospective case review of the treatment effects of amantadine on the mental, cognitive and clinical states of elderly chronic schizophrenic patients who received concomitant amantadine treatment and were routinely evaluated with the Positive and Negative Syndrome Scale, the Mini Mental State Examination, and Sandoz Clinical Assessment Geriatric Scale.

Results: No significant differences before and after amantadine treatment were noted. Conclusion: Amantadine did not influence the mental, cognitive and clinical states of elderly schizophrenia patients and thus can be considered as an anti-influenza preventive measure for this population, when indicated.

Background: Trans-aortic pressure gradient in patients with aortic stenosis and left ventricular systolic dysfunction is typically low but occasionally high.

Objectives: To examine the distribution of trans-aortic PG[1] in patients with severe AS[2] and severe LV[3] dysfunction and compare the clinical and echocardiographic characteristics and outcome of patients with high versus low PG.

Methods: Using the echocardiographic laboratory database at our institution, 72 patients with severe AS (aortic valve area ≤ 1.0 cm²) and severe LV dysfunction (LV ejection fraction ≤ 30%) were identified. The characteristics and outcome of these patients were compared.

Results: PG was high (mean PG ≥ 35 mmHg) in 32 patients (44.4%) and low (< 35 mmHg) in 40 (55.6%). Aortic valve area was slightly smaller in patients with high PG (0.63 ± 0.15 vs. 0.75 ± 0.16 cm² in patients with low PG, P = 0.003), and LV ejection fraction was slightly higher in patients with high PG (26 ± 5 vs. 22 ± 5% in patients with low PG, P = 0.005). During a median follow-up period of 9 months 14 patients (19%) underwent aortic valve replacement and 46 patients (64%) died. Aortic valve replacement was associated with lower mortality (age and gender-adjusted hazard ratio 0.19, 95% confidence interval 0.05–0.82), whereas trans-aortic PG was not (P = 0.41).

Conclusions: A large proportion of patients with severe AS have relatively high trans-aortic PG despite severe LV dysfunction, a finding partially related to more severe AS and better LV function. Trans-aortic PG is not related to outcome in these patients.

Background: The growing numbers of H1N1 "swine influenza" cases should prompt national health systems to achieve dual preparedness: preparedness of clinicians to recognize and treat cases of human H1N1 flu, and national preparedness for an influenza pandemic. This is similar to recent contingency planning for an avian flu pandemic.

Objectives: To evaluate hospital personnel's knowledge on avian flu (zoonotic, sporadic, pandemic), comparing among nurses, residents and faculty, and between those who attended lectures or other educational modalities targeted at avian flu and those who did not.

Methods: A 14 item multiple choice questionnaire was designed to test crucial points regarding preparedness for human avian flu. The directors of 26 general hospitals were instructed by the Ministry of Health to improve knowledge of and preparedness for different avian flu scenarios, and to expect an official inspection. As part of this inspection, we distributed the questionnaires to nurses, residents and senior physicians.

Results: Altogether, 589 questionnaires were collected from the 26 hospitals. Examinees who participated in training modules (course, lecture or any training provided by the hospital) did somewhat better (scoring 78 points out of 100) than those who did not attend the training (70 points) (P < 0.05). Differences in nurses’ knowledge were even more striking: 66 points for the non-attendants compared to 79 for nurses who attended the lecture (P < 0.05).  Residents had significantly lower scores compared to nurses or senior physicians: 70 compared to 77 and 78 respectively (P < 0.05).
