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 assess the nature of joint problems encountered in a geriatric inpatient population and evaluate the contribution of a rheumatologist.

Methods: We reviewed the rheumatology consultations that were conducted in a geriatric medical center over a 10 year period.

Results: A total of 474 consultations were held; most of these patients (86%) were hospitalized in the acute geriatric departments, 10% in the rehabilitation ward and 4% in the long-term care wards. Some patients were seen more than once. The rheumatologic joint problem was the main reason for hospitalization in 53% of these patients. Monoarthritis was the most frequent complaint (50%), followed by pauci-articular arthritis (two to five joints) in 30% of patients. Arthrocentesis, diagnostic and therapeutic, was performed in 225 patients, most of them on knee joints (81%). The most frequent diagnosis was osteoarthritis with acute exacerbation (28%), followed by gout (18%), pseudo-gout (9%) and rheumatoid arthritis (9%). In 86 cases (18%) the diagnosis was a non-specific rheumatologic problem: arthralgia, non-specific generalized pain, or fibromyalgia.

Conclusions: Prompt and appropriate evaluation, as well as arthrocentesis and treatment initiation, including local injections, were made possible by the presence of an in-house rheumatologist. 

Methods: In this retrospective multicenter open-label study we examined the efficacy and tolerability of VNS in patients in five adult and pediatric epilepsy centers in Israel. All patients had drug-resistant epilepsy and after VNS implantation in 2006–2007 were followed for a minimum of 18 months. Patients were divided into two age groups: < 21 and > 21 years old.

Results: Fifty-six adults and children had a stimulator implanted in 2006–2007. At 18 months post-VNS implantation, none of the patients was seizure-free, 24.3% reported a reduction in seizures of ≥ 75%, 19% reported a 50–75% reduction, and 10.8% a 25–50% reduction. The best response rate occurred in patients with complex partial seizures. Among these patients, 7 reported a ≥ 75% reduction, 5 patients a 50–75% reduction, 3 patients a 25–50% reduction, and 8 patients a < 25% reduction. A comparison of the two age groups showed a higher reduction in seizure rate in the older group (< 21 years old) than the younger group.

Conclusions: VNS is a relatively effective and safe palliative method for treating refractory epilepsy in both adults and children. It is an alternative treatment for patients with drug-resistant epilepsy, even after a relatively longed disease duration, who are not candidates for localized epilepsy surgery.

Objectives: To assess the preliminary results of transcatheter mitral valve leaflet repair (TMLR) in a single academic center.

Methods: Data were collected prospectively in the cardiology department of Rabin Medical Center in 2012. Ten consecutive patients (age 69.3 ± 15.9 years, ejection fraction 36.5 ± 9.4) who were poor surgical candidates with severe functional MR underwent general anesthesia, followed by trans-septal puncture and a TMLR procedure using the MitraClip device.

Results: All 10 patients were considered to have severe functional MR prior to TMLR treatment and were all symptomatic; the mean New York Heart Association (NYHA) class was 3.4 ± 0.5. The MR severity was 4 ± 0. There were no immediate complications or failures of the procedure. One patient died on day 5 due to massive gastrointestinal bleeding. Immediately following TMLR all 10 patients showed a profound MR reduction to a mean severity grade of 1.6 ± 0.6. At one month after the procedure, NYHA had decreased to an average of 1.7 ± 1.0 and was at least grade 2 in all but one patient. After 6 months the MR remained ≤ 2 in six of eight patients, with a NYHA average of 1.4 ± 0.5.

Conclusions: The MitraClip procedure was shown to be relatively safe, providing significant clinical benefits to a relatively sick population with severe MR. It is therefore an important alternative to surgery in these high risk patients.

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%).

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: Sudden death in athletes can occur during sport activities and is presumably related to ventricular arrhythmias.

Objectives: To investigate the long-term follow-up of athletes with ventricular arrhythmias during an exercise test.

Methods: From a database of 56,462 athletes we identified 192 athletes < 35 years old who had ventricular arrhythmias during an exercise test. Ninety athletes had ≥ 3 ventricular premature beats (VPB) (group A) and 102 athletes had ventricular couplets or non-sustained ventricular tachycardia (NSVT) during an exercise test (group B). A control group of 92 athletes without ventricular arrhythmias was randomly selected from the database (group C). Of the 192 athletes 39 returned for a repeat exercise test after a mean follow-up period of 70 ± 25 months and they constitute the study population.

Results: Twelve athletes from group A, 21 from group B and 6 from group C returned for a repeat exercise test. The athletes reached a significantly lower peak heart rate during their follow-up exercise test (P = 0.001). More athletes were engaged in competitive sports during their initial exercise test than in the follow-up test (P = 0.021). Most of the athletes who had VPB and/or ventricular couplets and/or NSVT during their initial exercise test had far fewer ventricular arrhythmias in the follow-up exercise test (P = 0.001).

Conclusions: Athletes engaged in competitive sports are more likely to develop ventricular arrhythmias during exercise. These arrhythmias subside over time when athletes are engaged in non-competitive sports.
