Objectives: To evaluate the safety and applicability of the Elekta Synergy-S radiation unit for the treatment of spinal tumors.

Methods: We retrospectively reviewed all patients treated with stereotactic radiosurgery to spinal tumors between November 2007 and June 2011.

Results: Thirty-four patients were treated for 41 lesions. Treatment indications were local tumor control and pain palliation. The mean follow-up was 10.8 ± 11.6 months (range 0.5–38 months). No acute radiation toxicity or new neurological deficits occurred during the follow-up period. Local tumor control was achieved in 21 of the 24 lesions (87.5%) available for radiological follow-up at a median of 9.8 months (range 3–32 months). Good analgesia was achieved in 24/30 lesions (80%) that presented with intractable pain.

Conclusions: The safety and feasibility of delivering single and multiple-fraction stereotactic spinal irradiation was demonstrated and became a standard treatment option in our institution. 

Objectives: To assess the first national simulation-based communication skills training for neurosurgical residents.

Methods: Eight scenarios covering different aspects of neurosurgery were developed by our team: 1) obtaining informed consent for an elective surgery, 2) discharge of a patient following elective surgery, 3) dealing with an unsatisfied patient, 4) delivering news of intraoperative complications, 5) delivering news of a brain tumor to parents of a 5 year old boy, 6) delivering news of brain death to a family member, 7) obtaining informed consent for urgent surgery from the grandfather of a 7 year old boy with an epidural hematoma, and 8) dealing with a case of child abuse. Fifteen neurosurgery residents from all major medical centers in Israel participated in the training. The session was recorded on video and was followed by videotaped debriefing by a senior neurosurgeon and communication expert and by feedback questionnaires.

Results: All trainees participated in two scenarios and observed another two. Participants largely agreed that the actors simulating patients represented real patients and family members and that the videotaped debriefing contributed to the teaching of professional skills.

Conclusions: Simulation-based communication skill training is effective, and together with thorough debriefing is an excellent learning and practical method for imparting communication skills to neurosurgery residents. Such simulation-based training will ultimately be part of the national residency program.

Methods:  Between February 2004 and June 2012, 100 patients in our department suffering from aortic aneurysm with aortic valve regurgitation underwent elective aortic valve-sparing surgery. Of them, 30 had Marfan syndrome, were significantly younger (30 ± 13 vs. 53 ± 16 years), and had a higher percentage of root aneurysm, compared with ascending aorta aneurysm in their non-Marfan counterparts. We evaluated the safety, durability, clinical and echocardiographic mid-term results of these patients.

Results: While no early deaths were reported in either group, there were a few major early complications in both groups. At follow-up (ranging up to 8 years with a mean of 34 ± 26 months) there were no late deaths, and few major late complications in the Marfan group. Altogether, 96% and 78% of the patients were in New York Heart Association functional class I-II in the Marfan and non-Marfan groups respectively. None of the Marfan patients needed reoperation on the aortic valve. Freedom from recurrent aortic valve regurgitation > 3+ was 94% in the Marfan patients.

Conclusions: Aortic valve-sparing surgery in Marfan symdrome patients is safe and yields good mid-term clinical outcomes.

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 investigate the predictive value of BNP levels regarding the severity of the postoperative course in infants undergoing surgical repair of congenital heart disease.

Methods: We conducted a prospective comparative study. Plasma BNP levels in infants aged 1–12 months with congenital heart disease undergoing complete repair were measured preoperatively and 8, 24 and 48 hours postoperatively. Demographic and clinical data included postoperative inotropic support and lactate level, duration of mechanical ventilation, intensive care unit (ICU) and hospitalization stay.

Results: Cardiac surgery was performed in 19 infants aged 1-12 months. Preoperative BNP level above 170 pg/ml had a positive predictive value of 100% for inotropic score ≥ 7.5 at 24 hours (specificity 100%, sensitivity 57%) and 48 hours (specificity 100%, sensitivity 100%), and was associated with longer ICU stay (P = 0.05) and a trend for longer mechanical ventilation (P = 0.12). Similar findings were found for 8 hours postoperative BNP above 1720 pg/ml. BNP level did not correlate with measured fractional shortening.

Conclusions: In infants undergoing heart surgery, preoperative and 8 hour BNP levels were predictive of inotropic support and longer ICU stay. These findings may have implications for preplanning ICU loads in clinical practice. Further studies with larger samples are needed.

Objectives: To review our use of ECMO over a 10 year period.

Methods: All children supported with ECMO from 2000 to 2010 were reviewed. Most of these children suffered from cardiac anomalies. The patients were analyzed by age, weight, procedure, RACHS-1 when appropriate, length of support, and outcome.

Results: Sixty-two children were supported with ECMO; their median age was 3 months (range 0–216 months) and median weight 4.3 kg (range 1.9–51 kg). Thirty-four patients (52.3%) needed additional hemofiltration or dialysis due to renal failure. The children requiring ECMO support represented a wide spectrum of cardiac lesions; the most common procedure was arterial switch operation 27.4% (n=17). ECMO was required mainly for failure to separate from the heart-lung machine (n=55). The median duration of ECMO support was 4 days (range 1–14 days); 29 (46.7%) patients were weaned successfully from ECMO during this time period, and 5 of them died during hospitalization, yielding an overall hospital survival rate of 38.7%.

Conclusions: ECMO support has significant survival benefit for patients with post-cardiotomy heart failure. Its early deployment should be considered in cardiopulmonary resuscitation.
