 Background: Postoperative pain is a common problem after cesarean deliveries.

Objectives: To characterize common obstetric anesthesia practices after cesarean deliveries in Israel in order to standardize postoperative pain relief protocols.

Methods: A questionnaire was completed during an interview with every obstetric anesthesia unit in all 25 delivery wards in Israel. Data were gathered on intraoperative anesthesia and analgesia protocols as well as postoperative pain relief protocols. A sub-analysis compared units whose director completed a formal obstetric anesthesia training program with those whose directors did not.

Results: Neuraxial morphine was used routinely in 12% of hospitals. No unit providing intrathecal morphine complied with American Society of Anesthesiologists guidelines for respiratory monitoring after use of neuraxial opioids. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) were used routinely in only half the wards, while patient-controlled analgesia was used infrequently. Postoperative verbal analog scores were not recorded routinely in 71% of units on postoperative day 1. The unit director's training significantly influenced the unit protocols.

Conclusions: Intrathecal morphine, the gold standard of care in cesarean deliveries, is rarely used, mainly due to shortage of staff and lack of formal obstetric anesthesia training. In addition, NSAIDs are also underused. There is a need for more formal training for obstetric anesthesiologists in Israel.

 Background: Physicians are often insufficiently trained in bedside teaching and mentoring skills. Objectives: To develop, implement and assess a simulation-based training program designed to improve clinical teaching among physicians.

Methods: We developed a one-day tutor training program based on six simulated scenarios with video-based debriefing. The program's efficacy was assessed using questionnaires completed by the participating physicians and their students. Main outcome measures were self-perceived teaching skills at baseline, after participation in the program, and following completion of the tutor role. Secondary outcome measures were the students' perceptions regarding their tutor skills.

Results: Thirty-two physicians (mean age 35.5, 56% females) participated in the program. Self-assessment questionnaires indicated statistically significant improvement following the program in 13 of 20 measures of teaching skills. Additional improvement was observed upon completion of the tutor role, leading to significant improvement in 19 of the 20 measures. Questionnaires completed by their students indicated higher scores in all parameters as compared to a matched control group of tutors who did not participate in the program, though not statistically significant. Most participants stated that the program enhanced their teaching skills (88%), they implement program-acquired skills when teaching students (79%), and they would recommend it to their peers (100%). Satisfaction was similar among participants with and without previous teaching experience.

Conclusions: A novel one-day simulation-based tutor training program was developed and implemented with encouraging results regarding its potential to improve clinical teaching and mentoring skills.

Background: Bisphosphonates reduce the overall risk of fractures among patients with osteoporosis, and this beneficial effect is long-lasting. However, since bisphosphonates inhibit bone remodeling, they may enhance the formation and propagation of micro-cracks over time and patients may therefore be prone to atypical fatigue fractures, mainly in the subtrochanteric region and femoral shaft.

Objectives: To present two cases of subtrochanteric fractures related to bisphosphonate treatment and review of the current literature.

Conclusions: Despite the overall beneficial effect of bisphosphonates, further research is required to prevent this significant complication.

 With our increased understanding of cancer cell biology, molecular imaging offers a strategic bridge to oncology. This complements anatomic imaging, particularly magnetic resonance (MR) imaging, which is sensitive but not specific. Among the potential harms of false positive findings is lowered adherence to recommended surveillance post-therapy and by persons at increased cancer risk. Positron emission tomography (PET) plus computed tomography (CT) is the molecular imaging modality most widely used in oncology. In up to 40% of cases, PET-CT leads to changes in therapeutic management. Newer PET tracers can detect tumor hypoxia, bone metastases in androgen-sensitive prostate cancer, and human epidermal growth factor receptor type 2 (HER2)-expressive tumors. Magnetic resonance spectroscopy provides insight into several metabolites at the same time. Combined with MRI, this yields magnetic resonance spectroscopic imaging (MRSI), which does not entail ionizing radiation and is thus suitable for repeated monitoring. Using advanced signal processing, quantitative information can be gleaned about molecular markers of brain, breast, prostate and other cancers. Radiation oncology has benefited from molecular imaging via PET-CT and MRSI. Advanced mathematical approaches can improve dose planning in stereotactic radiosurgery, stereotactic body radiotherapy and high dose-rate brachytherapy. Molecular imaging will likely impact profoundly on clinical decision making in oncology. Molecular imaging via MR could facilitate early detection, especially in persons at high risk for specific cancers.

 Background: Transcatheter aortic valve implantation (TAVI) has recently become an alternative to surgical aortic valve replacement in selected patients with high operative risk.

Objectives: To investigate the 30 day clinical outcome of the first 300 consecutive patients treated with transfemoral TAVI at the Tel Aviv Medical Center.

Methods: The CoreValve was used in 250 patients and the Edwards-Sapien valve in 50 patients. The mean age of the patients was 83 ± 5.3 years (range 63–98 years) and the mean valve area 0.69 ± 0.18 cm2 (range 0.3–0.9 cm2); 62% were women.

Results: The procedural success rate was 100%, and 30 day follow-up was done in all the patients. The average Euro-score for the cohort was 26 ± 13 (range 1.5–67). Total in-hospital mortality and 30 day mortality were both 2.3% (7 patients). Sixty-seven patients (22%) underwent permanent pacemaker implantation after the TAVI procedure, mostly due to new onset of left bundle brunch block and prolonged PR interval or to high degree atrioventricular block. The rate of stroke was 1.7% (5 patients). Forty-one patients (13.7%) had vascular complications, of whom 9 (3%) were defined as major vascular complications (according to the VARC definition).

Conclusions: The 30 day clinical outcome in the first 300 consecutive TAVI patients in our center was favorable, with a mortality rate of 2.3% and low rates of stroke (1.7%) and major vascular complications (3%).

 Background: Osteoporosis is considered the most common bone disease in humans and the most common cause of fractures.

Objectives: To identify possible risk factors associated with a decreased level of care for osteoporosis among patients presenting acutely with the major types of fragility fractures, but also among patients who remain undertreated following their discharge.

Methods: We conducted a retrospective questionnaire-based cohort study. We searched our databases for patients admitted acutely with proximal humerus, distal forearm, thoracolumbar spine, and proximal femur fractures. A questionnaire was used to evaluate osteoporotic care including a referral to DEXA and any associated prescribed medication.

Results: The study group included 114 patients or their caregivers. The osteoporosis care rate rose from 56.1% (n=64) before admission to 71% (n=81) at follow-up. Significant risk factors associated with a decreased care rate prior to admission were the presence of fewer than three comorbidities, and a combination of male gender and young age. Continued neglect at follow-up was associated with the opposite risk factors, such as older age, multiple comorbidities, and polypharmacy. An additional finding was that treated patients had a significantly increased likelihood of presenting with vertebral fractures.

Conclusions: While the association of osteoporosis with the elderly may decrease its screening rates among younger and healthier patients, fragility fractures may be viewed as “end-stage” bone disease, rendering osteoporotic care inefficient.

Background: Stentless aortic bioprostheses were designed to provide improved hemodynamic performance and potentially better survival.

Objectives: To report the outcomes of patients after aortic valve replacement with the Freestyle® stentless bioprosthesis in the Tel Aviv Medical Center followed for ≤ 15 years.

Methods and Results: Between 1997 and 2011, 268 patients underwent primary aortic valve replacement with a Freestyle bioprosthesis, 211 (79%) of them in the sub-coronary position. Mean age, Charlson comorbidity index and Euro-score were 71.0 ± 9.2 years, 4.2 ± 1.5 and 10.2 ± 11 respectively, and 156 (58%) were male. Peak and mean trans-aortic gradient decreased significantly (75.0 ± 29.1 vs. 22.8 ± 9.6 mmHg, P < 0.0001; and 43.4 ± 17.2 vs. 12.1 ± 5.4 mmHg, P < 0.0001 respectively) in 3 months of follow-up. Mean overall follow-up was 4.9 ± 3.1 years and was complete in all patients. In-hospital mortality was 4.1% (n=11) but differed significantly between the first 100 patients operated before 2006 and the last 168 patients operated after January 2006 (8 vs. 3 patients, 8.0% vs. 1.8%, P = 0.01). Overall, 5 and 10 year survival rates were 85 ± 2.5% and 57.2 ± 5.7%, respectively. Five year survival was markedly improved in patients operated after January 2006 compared to those operated in the early years of the experience (92.3 ± 2.3% vs. 76.0 ± 4.4%, P = 0.0009). All the 21 octogenarians operated after January 2006 survived surgery, with excellent 5 year survival (85.1 ± 7.9%). Six patients required reoperation during follow-up: structural valve deterioration in five and endocarditis in one.

Conclusions: Aortic valve replacement with the Freestyle bioprosthesis provides good long-term hemodynamic and clinical outcomes, even in octogenarians. Valve calcification is the major (and rare) mode of valve deterioration leading to reoperation in these patients.

 Background: Predicting mortality is important in treatment planning and professional duty towards patients and their families.

Objectives: To evaluate the predictive value regarding patients' survival once the diagnosis of “general deterioration” replaces an ICD-9 diagnosis upon re-admission.

Methods: In a retrospective cohort case-control study, we screened the records of patients re-admitted at least three times during the past 2 years. For each patient's death during the third hospitalization, we matched (for age and gender) a patient who survived the third hospitalization. We evaluated 14 parameters potentially accountable for increased risk of mortality, e.g., length of stay at each admission, interval to re-admission, etc. We applied a multifactorial analysis using logistic regression to predict the risk of mortality during the third hospitalization as potentially affected by the aforementioned parameters.

Results: The study included 81 study patients and 81 controls. Of the 14 parameters potentially explaining an increased risk of mortality during the third hospitalization, several were found to be statistically significant. The most significant was the diagnostic switch from a specific ICD-9 diagnosis on first admission to the non-specific diagnosis of “general deterioration” at the second hospitalization. In such cases, the risk of death during the third hospitalization was increased by 5300% (odds ratio = 54, P = 0.008). The increased risk of mortality was not restricted to patients with malignancy as their background diagnosis.

Conclusions: At re-admission, a switch from disease-specific diagnosis to the obscure diagnosis “general deterioration” increases the subsequent risk of mortality.

 Background: Smoking is a serious health issue worldwide. Smoking trends among physicians predict similar trends in the general population. Little is known about current smoking rates among physicians.

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.

 Background: Colon cancer is common, affecting mostly older people. Since age is a risk factor, young patients might not be awarded the same attention as older ones regarding symptoms that could imply the presence of colon cancer.

Objectives: To investigate whether young patients, i.e., under age 50, complain of symptoms for longer than older patients until the diagnosis of colon cancer is established.

Methods: In this retrospective cohort study, patients were divided into two groups: < 50 years old (group 1) and ≥ 50 (group 2). All had undergone surgery for left or right colon cancer during the 1 year period January 2000 through December 2009 at one medical center. Rectal and sigmoid cancers were excluded. Data collected included age, gender, quantity and quality of complaints, duration of complaints, in-hospital versus community diagnosis, pathological staging, the side of colon involved, and overall mortality. The main aim was the quality and duration of complaints. Secondary outcomes were the pathological stage at presentation and the mortality rate.

Results: The study group comprised 236 patients: 31 (13.1%) were < 50 years old and 205 (86.9%) were ≥ 50 years. No significant difference was found in the quantity and quality of complaints between the two groups. Patients in group 1 (< 50 years) complained for a longer period, 5.3 vs. 2.4 months (P = 0.002). More younger patients were diagnosed with stage IV disease (38.7% vs. 21.5%, P = 0.035) and fewer had stage I disease (3.2% vs. 15.6%, P = 0.06); the mortality rates were similar (41.9% vs. 39%). Applying a stepwise logistic regression model, the duration of complaints was found to be an independent predictor of mortality (P = 0.03, OR 1.6, 95% CI 1–3.6), independently of age (P = 0.003) and stage (P < 0.001).

Conclusions: Younger patients are more often diagnosed with colon cancer later, at a more advanced stage. Alertness to patients’ complaints, together with evaluation regardless of age but according to symptoms and clinical presentation are crucial. Large-scale population-based studies are needed to confirm this trend.
