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.

Objectives: To report the first results from the Serbian National Cohort study, which was started in January 2000.

Methods: Our study included 374 patients: 260 primary APS patients and 114 SLE patients with secondary APS. Antiphospholipid antibody (aPL) analysis included detection of anticardiolipin antibodies (aCL) (immunoglobulin G and M), ß₂-glycoprotein 1, and lupus anticoagulant. Echocardiography was performed in all patients, and data on myocardial infarction, unstable angina, chronic cardiomyopathy and acute heart failure were collected.

Results: There were 30.7% secondary APS patients and 9.2% primary APS patients with pseudo-infective endocarditis (P = 0.0001). Cardiac manifestations were observed in 28.7% of patients who had more than one type of antibody (category I), in 24.1% with category IIa, in 23.1% with category IIb, and in 27.8% with category IIc (P = 0.78). Age was confirmed as a significant factor for cardiac manifestations in APS patients (52.3 and 43.3 years, respectively, P = 0.001). aCL IgG and IgM positivity was related to valvular changes in all APS patients and high levels of those antibodies increased the risk of these manifestations.

Conclusions: Patients with secondary APS had a higher prevalence of valvular lesions, and some aPL types and high levels of aPL were risk factors for specific cardiac manifestations in APS patients.

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. 

Objectives: To present our initial experience with MitraClip implantation in 20 high risk patients at Sheba Medical Center.

Methods: Twenty high surgical risk patients with symptomatic significant MR underwent MitraClip implantation. Clinical and echocardiographic parameters were recorded at baseline and at follow-up.

Results: The patients’ mean age was 76 years and 65% were male. Coronary artery disease was present in 85% and 45% had previous bypass surgery. Renal failure was present in 65%, atrial fibrillation in 60%, and 30% had an implantable cardioverter defibrillator/cardiac resynchronization therapy device. Mean left ventricular ejection fraction was 36%. Grade III-IV MR was present in all patients with the vast majority suffering from functional MR secondary to ventricular remodeling. New York Heart Association (NYHA) class was III-IV in 90%. Patients were followed for a mean of 231 days. Acute reduction of MR grade to ≤ 2 was accomplished in 19 of the 20 patients (95%) with a 30 day mortality of 5%. At follow-up MR was reduced to ≤ 2 in 64% of patients, and NYHA class improved in 70% of patients. An additional 2 patients (11%) died during follow-up.

Conclusions: MitraClip implantation is feasible and safe in high risk highly symptomatic patients with significant MR. Acute and mid-term results are comparable to similar high risk patient cohorts in the literature. Continued surveillance and longer follow-up are needed to elucidate which patients are most likely to benefit from the procedure.

Objectives: To measure the tumor-to-breast volume ratio using MRI in order to assess whether there is a correlation between this ratio and the type of surgery selected (breast-conserving or mastectomy).

Methods: The volumes of the tumor and the breast and the tumor-to-breast volume ratio were retrospectively calculated using preoperative breast MRI in 76 patients who underwent breast-conserving surgery or mastectomy.

Results: Breast-conserving surgery (lumpectomy) was performed in 64 patients and mastectomy in 12. The average tumor-to-breast volume ratio was 0.06 (6%) in the lumpectomy group and 0.30 (30%) in the mastectomy group (P < 0.0001).

Conclusion: The tumor-to-breast volume ratio correlated with the type of surgery. As measured on MRI, this ratio is an accurate means of determining the type of surgery best suited for a given patient. It is recommended that MRI-determined tumor-to-breast volume ratio become part of the surgical planning protocol for patients diagnosed with breast cancer.

Objectives: To demonstrate the efficacy of rhTSH in radioiodine thyroid ablation in patients with differentiated thyroid cancer.

Methods: We conducted a retrospective study of patients who underwent total thyroidectomy for well-differentiated thyroid cancer with different levels of risk, treated with rhTSH prior to remnant ablation with radioiodine.  

Results: Seventeen patients with thyroid cancer were studied and followed for a median of 25 months (range 8–49 months). Ablation (defined as stimulated thyroglobulin < 1 mg/ml, negative neck ultrasonography, and radioiodine scan) was successful in 15 patients (88.2%). One of the patients was lost to follow-up.

Conclusions: The use of rhTSH with postoperative radioiodine ablation may be an efficient tool for sufficient thyroid remnant ablation, avoiding hypothyroidal state in the management of thyroid cancer patients.

Objectives: To describe a single-center experience with fenestrated and branched endografts for the treatment of complex aortic aneurysms.

Methods: We reviewed all cases of complex aortic aneurysms treated with branched or fenestrated devices in our center. Data collected included device specifics, perioperative morbidity and mortality, re-intervention rates and mid-term results.

Results: Between 2007 and 2012 nine patients were treated with branched and fenestrated stent grafts. Mean age was 73 years. Mean aneurysm size was 63 mm. Perioperative mortality was 22% (2/9). During the follow-up, re-interventions were required in 3 patients (33%). Of 34 visceral artery branches 33 remained patent, resulting in a patency rate of 97%. Sac expansion was seen in a single patient due to a large endoleak. No late aneurysm- related deaths occurred.

Conclusions: Branched and fenestrated stent grafts are feasible and relatively safe alternatives for the treatment of complex aortic aneurysms involving the visceral segment. Further research is needed to determine the long-term durability of this new technology.
