Methods: We evaluated 11 patients with catastrophic APS – 8 of them with a probable diagnosis of catastrophic APS and 3 with a definite diagnosis – admitted to Beilinson hospital during the period 2003–2011.

Results: Overall venous events numbered 18 and overall arterial events 10. The event duration per patient was 2.6 ± 1.2 weeks (mean ± SD). Deep vein thrombosis of the legs was quite common (7 events), as was venous intraabdominal thrombosis (10 events). Eight patients had microangiopathic anemia with schizocytes seen in the blood smear. The mean ± SD hemoglobin level was 10.3 ± 3.6 g/dl and the mean ± SD creatinine level 0.98 ± 0.78 mg/dl. All our patients had high acute-phase reactant and all had lupus anticoagulant positivity, The most common positive antibodies were immunoglobulin G anticardiolipin (8 patients) and IgG[1] β2-glycoprotein (7 patients). During the events warfarin was stopped and the patients were given intravenous heparin. All the patients received steroids in variable doses. Five patients underwent plasma exchange, two patients received rituximab and two patients intravenous immunoglobulin.

Conclusions: Catastrophic APS, a rare syndrome, is important because of its major morbidity and mortality among young 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. 

Objectives: To evaluate the long-term outcome of indwelling voice prostheses inserted during (primary procedure) or after (secondary procedure) total laryngectomy.

Methods: The study group included 90 patients who underwent total laryngectomy and tracheoesophageal puncture (TEP) with placement of voice prosthesis at a tertiary medical center during the period 1990–2008. Background, clinical and outcome data were collected by medical file review. Findings were compared between patients in whom TEP was performed as a primary or a secondary procedure.

Results: TEP was performed as a primary procedure in 64 patients and a secondary procedure in 26. Corresponding rates of satisfactory voice rehabilitation were 84.4% and 88.5% respectively. There was no association of voice quality with either receipt of adjuvant radiation/chemoradiation or patient age. The average lifetime of the voice prosthesis was 4.2 months for primary TEP and 9.06 months for secondary TEP (p = 0.025).

Conclusions: Primary TEP provides almost immediate and satisfactory voice rehabilitation. However, it is associated with a significantly shorter average prosthesis lifetime than secondary TEP. Chemoradiotherapy and patient age do not affect voice quality with either procedure.

Background: The pathophysiology of aortic stenosis (AS) involves inflammatory features including infiltration of the aortic valve (AV) by activated macrophages and T cells, deposition of lipids, and heterotopic calcification.

Objectives: To evaluate the correlation between white blood cell (WBC) differential count and the occurrence and progression of AS.

Methods: We identified in our institutional registry 150 patients with AS who underwent two repeated echo studies at least 6 months apart. We evaluated the association between the average of repeated WBC differential counts sampled during the previous 3 years and subsequent echocardiographic AS indices.

Results: There was no significant difference in total WBC, lymphocyte or eosinophil count among mild, moderate or severe AS groups. There was a progressive decrease in monocyte count with increasing AS severity (P = 0.046), more prominent when comparing the mild and severe groups. There was a negative correlation between AV peak velocity or peak or mean gradient and monocyte count in the entire group (r = -0.31, -0.24, and -0.25 respectively, all P ≤ 0.01). Similar partial correlations controlling for age, gender, hypertension, smoking, dyslipidemia and ejection fraction remained significant. The median changes over time in peak velocity and peak gradients in AS patients were 0.44 (0–1.3) m/sec/year and 12 (0–39) mmHg/year, respectively. There was no correlation between any of the WBC differential counts and the change in peak velocity or peak gradient per year.

Conclusions: Severe AS is associated with decreased total monocyte count. These findings may provide further clues to the mechanism underlying the pathogenesis of aortic stenosis.

Background: The articular surface replacement (ASR) total hip arthroplasty (THA) was recently recalled from the market due to high failure rates. This modality was used frequently by surgeons at our medical center.

Objectives: To assess the clinical and radiographic outcomes in patients following the surgery and determine the revision rate in our cohort.

Methods: Between 2007 and 2010 139 hips were operated on and evaluated in our clinic. All patients underwent a clinical interview, function and pain evaluation, as well as physical examination and radiographic evaluation. When necessary, patients were sent for further tests, such as measuring cobalt-chromium levels and magnetic resonance hip imaging. Results: With an average follow-up of 42 months the revision rate was 2% (3/139). Patients reported alleviation of pain (from 8.8 to 1.7 on the Visual Analog Scale, P < 0.001), good functional outcomes on the Harris Hip Score, and improved quality of life. Overall satisfaction was 7.86 on the reversed VAS[1]. For patients who required further tests, clinical and radiographic outcomes were significantly poorer than for the rest of the cohort. Average blood ion levels were high above the normal (cobalt 31.39 ppb, chromium 13.32 ppb), and the rate of inflammatory collection compatible with pseudotumors on MRI was 57%.

Discussion: While our study favors the use of the ASR implant both clinically and radiographically, some patients with abnormal ion levels and inflammatory collections on MRI might require revision in the future. 

Objectives: To evaluate health utilization patterns in two primary care clinics in southern Israel: one under continuous attacks of Qassam rockets as compared with a similar clinic not under a rocket threat.

Methods: We conducted a retrospective cross-sectional study in two primary care clinics in southern Israel, with 11,630 persons listed in the two clinics during the entire study period. The primary outcome measures were total annual number of visits per person to the clinic and for specific diagnoses, and the number of drug prescriptions issued, emergency room (ER) visits, hospitalization days, cardiac catheterizations and coronary bypass surgeries.

Results: In both clinics there was an increase over time in the mean annual number of visits per person. During the years of severe attacks there was an increase in visits with a chief complaint of depression and anxiety and an increase in the number of anxiolytic prescriptions in the study clinic compared with the control. During the same period there was a decrease in the number of ER visits in the study clinic compared with the control.

Conclusions: The population under continuous life-threatening events showed more depression and anxiety problems. Under severe bombardment, the residents prefer not to leave home, unless necessary.

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 compare the incidence rate of overall and site-specific cancers among Israeli Arabs with T2DM to that of Israeli Arabs without.

Methods: A retrospective cohort study of all adult Arab members of Clalit Healthcare Services in northern Israel was conducted over a 10 year period (1999–2008).

Results: During the study period 752 and 2045 incident cases of cancer were diagnosed among 13,450 adults with diabetes and 74,484 without, respectively. The follow-up time involved 817,506 person-years. Diabetes was associated with a standard incidence ratio (SIR) of 3.27 (95%CI 1.49–5.05) and 2.87 (95%CI 1.25–4.50) for pancreatic cancer in men and women, respectively. A significantly reduced SIR (0.67, 95%CI 0.36–0.99) was observed for esophageal, stomach and intestinal cancers in men.

Conclusions: Our findings support an association between T2DM and increased risk of cancer of the pancreas in Arab men and women. A significantly reduced risk of all other cancers was observed only in Arab men. Our findings underscore the need for effective diabetes and cancer prevention and intervention programs.
