Background: The coronavirus disease 2019 (COVID-19) pandemic caused significant global turmoil, including changes in social and societal conduct such as lockdowns, social isolation, and extensive regulations. These changes can be major sources of stress. The first wave of the pandemic (April–May 2020) was a time of global uncertainty. We evaluated symptom severity among 29 Israeli children and adolescents with obsessive-compulsive disorder (OCD). Our previous study found that most of these participants did not experience an exacerbation of symptoms.

Objective: To re-evaluate the OCD symptoms of 18 participants from the original group of 29 children and adolescents during three time points: before the pandemic, during the first wave, and 2 years later.

Methods: Obsessive-compulsive symptoms (OCS) were assessed using the Clinical Global Impression Scale (CGI), a functional questionnaire, and the Obsessive-Compulsive Inventory-child version (OCI-CV).

Results: OCS in patients did not change significantly during the three time points. Participants reported minimal changes in their general functioning 2 years after the outbreak of COVID-19 and showed minimal change in OCI-CV scale scores.

Conclusions: Our results indicated clinical stability of OCD symptoms among most of the participants.

Background: Advanced heart failure (HF) carries a high rate of recurrent HF hospitalizations and a very high mortality rate. Mechanical devices and heart transplantation are limited to a select few. Dialysis may be a good alternative for advanced HF patients with volume overload despite maximal pharmacological therapy.

Objectives: To assess the net clinical outcome of peritoneal dialysis or hemodialysis in patients with advanced HF.

Methods: We analyzed all advanced HF patients who were referred for dialysis due to volume overload in our institution. Patients were followed for complications, HF hospitalizations, and survival.

Results: We assessed 35 patients; 10 (29%) underwent peritoneal dialysis and 25 (71%) underwent hemodialysis; 71% were male; median (interquartile range) age was 74 (67–78) years. Estimated glomerular filtration rate was 20 (13–32) ml/min per 1.73 m². New York Heart Association functional capacity was III. Median follow-up time was 719 days (interquartile range 658–780). One-year mortality rate was 8/35 (23%) and overall mortality rate was 16/35 (46%). Three patients (9%) died during the first year due to line or peritoneal dialysis related sepsis, and 6 (17%) died during the entire follow-up. The median number of HF hospitalizations was significantly reduced during the year on dialysis compared to the year prior to dialysis (0.0 [0.0–1.0] vs. 2.0 [0.0–3.0], P < 0.001).

Conclusions: Dialysis is reasonably safe and significantly reduced HF hospitalization in advanced HF patients. Dialysis could be a good alternative for advanced HF patients with intractable volume overload.

Background: Evaluation of children's anthropometrics poses challenges due to age-related changes. The main focus is on height and weight. However, since weight is height-dependent, body mass index (BMI) is the best surrogate measurement of adiposity. Israel has not developed national growth tables; therefore, researchers and clinicians utilize either World Health Organization (WHO) or U.S. Centers for Disease Control and Prevention (CDC) tables as benchmarks.

Objectives: To evaluate the anthropometrics of Israeli children benchmarked by CDC and WHO tables.

Methods: A retrospective review was conducted of the 1987–2003 birth cohort (age 4–18 years) from Clalit Health Services databases. Anthropometrics were retrieved twice: at study entry and one year later. We evaluated them as separate cohorts. Gender-specific age-matched median height and BMI were compared with CDC and WHO height and BMI tables.

Results: The study consisted of 15,650, mean age at study entry 9.5 years (range 4–18). Gender-specific median heights of the Israeli children were similar to CDC and WHO values at younger ages, but were slightly shorter than the age-matched CDC and WHO toward the age of final height in both cohorts. However, gender-specific median BMI was considerably and statistically significant higher compared to CDC and WHO values consistently along the entire age range in both cohorts.

Conclusions: Israeli children were slightly shorter toward the age of final height, compared to WHO and CDC. However, BMI in Israeli children was significantly higher compared to the CDC and WHO consistently along the age range, which raises an alarm regarding obesity patterns

Background: Understanding the mechanism and the main components involved in rheumatic mitral regurgitation (MR) associated with dominant pliable mitral stenosis (MS) may improve our ability to repair some mixed rheumatic mitral valve pathologies.

Objectives: To assess mitral valve structural components in pure mitral stenosis versus mitral stenosis associated with mild regurgitation

Methods: Using two-dimensional echocardiography, we performed mitral valve structural analysis in two groups of patients prior to balloon mitral valvuloplasty (BMV). The first group, consisting of 13 females and 2 males (mean age 39 ± 5 years), suffered from pure pliable mitral stenosis (PPMS), while the second group, with 22 females and 2 males (mean age 44 ± 5 years), had mixed mitral valve disease (MMVD) characterized by mild MR in the presence of dominant pliable MS. All echocardiographic measurements relating to the mechanism of MR were undertaken during the systolic phase.

Results: The mean Wilkins scores of the PPMS and MMVD groups were 7 ± 1 and 8 ± 1 respectively (P = 0.004). No significant differences were found between the MMVD group and the PPMS group regarding annular circumference (15.5 ± 1.4 cm vs. 15.4 ± 1.6 cm, P = 0.84), annular diameter (36 ± 4 mm vs. 38 ± 5 mm, P = 0.18), and chordae tendinae length directed to the anterior mitral leaflet (AML) (10 ± 2 mm vs. 11 ± 2 mm, P = 0.137). However, anterior vs. posterior mitral leaflet length during systole was significantly lower in the MMVD than in the PPMS group (2.2 ± 0.5 vs. 2.8 ± 0.4, P = 0.02), whereas the AML thickness at the co-aptation point was greater in the MMVD than in the PPMS group (7 ± 1 vs. 5 ± 1 mm, P = 0.0004).

Conclusions: In rheumatic valves, thickening and shortening of the AML are the main factors determining the appearance of mild MR in the presence of dominant pliable MS.

Background: Children report various types of fear in the context of hospitalization, such as fear of separation from the family, having injections and blood tests, having to stay in the hospital for a long time, and being told “bad news” about their health.

Objectives: To examine the effects of the “Teddy Bear Hospital” method on preschool children’s fear of future hospitalization.

Methods: The study group comprised 41 preschool children aged 3–6.5 years (mean 5.1 ± 0.7 years), and 50 preschool children, age matched and from a similar residential area, served as the control group. Assessment included a simple one-item visual analog scale of anxiety about hospitalization. This was assessed individually one day prior to the intervention and again a week after the intervention in both groups

Results: While baseline levels of anxiety were not different between groups [t(89) = .4, NS], children in the “Teddy Bear Hospital” group reported significantly lower levels of anxiety than the control group at follow-up

Conclusions: Our results indicate that by initiating a controlled pain-free encounter with the medical environment in the form of a “Teddy Bear Hospital,” we can reduce children’s anxiety about hospitalization.

Objectives: To determine whether there is an association between the presence and severity of adult calcific aortic stenosis and Chlamydia pneumoniae seropositivity

Methods: Forty adult patients (23 women, 17 men) were divided into three groups according to echocardiographic aortic valve area: Group A – 7 symptomatic subjects (age 67 ± 7 years) with normal aortic valve and normal coronary angiogram, Group B – 16 patients (age 73 ± 6) with moderate ACAS[1] (AVA[2]> 0.8 £ 1.5 cm²), and Group C – 17 patients (age 76 ± 7) with severe ACAS (AVA £ 0.8 cm²). We tested for immunoglobulins M, G and A as retrospective evidence of C. pneumoniae infection using the micro-immunofluorescence method. Past C. pneumoniae infection was defined by IgG titer > 16 £ 512.

Results: No patients in Group A showed positive Ig[3] for C. pneumoniae. IgM was not detected in any of the patients with ACAS (groups B and C) while 2 of 17 patients (12%) in group C showed IgA for the pathogen. High titers of IgG were found in 14 of 33 (42%) of the patients with moderate or severe ACAS: 5 of 16 (31%) in group B and 9 of 17 (53%) in group C (P = 0.2). Both groups had the same prevalence of coronary artery disease (66%). AVA was lower in IgG-seropositive patients than in the seronegative group (0.88 ± 0.3 cm² vs. 1.22 ± 0.4 cm², respectively, P = 0.02).

Conclusions: Past C. pneumoniae infection may be associated with a higher prevalence and greater severity of ACAS.

Background: Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization.

Objective: To analyze the reasons for urgent cardiac surgery and mortality in the different phases of our laboratory’s activity in the last 11 years, and examine the impact of the new interventional and therapeutic modalities on the current need for on-site cardiac surgical backup.

Methods: We retrospectively reviewed the mortality and need for urgent cardiac surgery (up to 12 hours post-catheterization) through five phases of our laboratory’s activity: a) diagnostic (years 1989–2000), b) valvuloplasties and other non-coronary interventions (1990–2000), c) percutaneous-only balloon angioplasty (1992–1994), d) coronary stenting (1994–2000), and e) use of IIb/IIIa antagonists and thienopiridine drugs (1996–2000).

Results: Forty-eight patients (0.45%) required urgent cardiac surgery during phase 1, of whom 40 (83%) had acute coronary syndromes with left main coronary artery stenosis or the equivalent, and 8 (17%) had mechanical complications of acute myocardial infarction. Two patients died (0.02%) during diagnostic procedures. In phase 2, eight patients (2.9%) were referred for urgent cardiac surgery due to either cardiac tamponade or severe mitral regurgitation, and two patients (0.7%) died. The combined need for urgent surgery and mortality was significantly lower in phase 4 plus 5 as compared to phase 3 (3% vs. 0.85%, P = 0.006).

Conclusion: In the current era using coronary stents and potent antithrombotic drugs, after gaining experience and crossing the learning curve limits, complex cardiac therapeutic interventions can safely be performed without on-site surgical backup.
