Recognizing myocarditis is a diagnostic and therapeutic challenge due to the heterogeneity of its clinical presentation and the wide range of etiologies. There is a lack of uniformity among position papers and guidelines from various professional societies regarding the definition and diagnostic workout, including recommendations for performing endomyocardial biopsy (EMB) and medical management, especially the use of immunosuppressive regimens [1-3]. Moreover, there is significant variability among medical centers in Israel in the diagnostic and therapeutic approaches to acute myocarditis. The purpose of this position paper is to present ways to standardize the management of acute myocarditis in Israel [4] by providing up-to-date definitions of the clinical categories of myocarditis, diagnostic criteria, and therapeutic approaches that correspond to the realities of our healthcare system.

In the position statement on the definition and diagnosis of acute myocarditis on page XXX of this issue of the Israel Medical Association Journal (IMAJ), we discussed contemporary criteria for definition of acute myocarditis and inflammatory cardiomyopathy [1-6]. We also addressed current diagnostic methods including indications for endomyocardial biopsy (EMB) [7-21]. In this position statement, we discuss the management approaches during hospitalization and following hospital discharge, including specific forms of myocarditis and recommendations for returning to physical activity after myocarditis [21-36].

Background: Peripartum cardiomyopathy (PPCM) is a rare but potentially devastating complication of pregnancy. Although the pathophysiology of PPCM is not fully understood, there are known risk factors for developing PPCM, which are maternal and gestation related. In the first wave of the coronavirus disease 2019 (COVID-19) pandemic, we witnessed an elevated incidence of PPCM among COVID-19 survivors.
Objectives: To present a single-center case series of three patients diagnosed with peripartum cardiomyopathy after recovered from COVID-19 during the index pregnancy.
Methods: In this single center case study, all patients diagnosed with PPCM at our institute during the examined time frame were included. Electronic medical records were studied.
Results: Three patients previously diagnosed with asymptomatic or mildly symptomatic COVID-19 disease during pregnancy presented with PPCM before or shortly after delivery. Patients underwent testing to rule out residual COVID-19 myocarditis, were treated pharmacologically and with wearable defibrillators as needed, and were examined in follow-up 1–9 months after delivery.
Conclusions: Residual endothelial damage due to COVID-19 disease, even if originally mild in presentation, could predispose pregnant patients to PPCM and should be considered as a risk factor when assessing patients with new onset symptoms of heart failure. Further research is needed to confirm this hypothesis and fully determine the underlying pathophysiology. These preliminary findings warrant a high index of suspicion for PPCM in COVID-19 recoverers.

Background: Brucellosis is an endemic infection affecting the Mediterranean Basin, Arabian Peninsula, India, Mexico, and South America. Data on brucellosis infections in children are limited.
Objectives: To review and characterize the clinical presentation of pediatric patients diagnosed with brucellosis in a tertiary medical center.
Methods: Retrospective data analysis was conducted on all pediatric patients from January 2010 to December 2020 admitted to the pediatric department with a diagnosis of brucellosis based on a positive serology test or growth of Brucella bacteria in blood culture.
Results: The study comprised 53 children aged 0–18 years. The mean age at presentation was 11.01 ± 4.91 years; 39 male (73.6%). Pre-infection exposure to unpasteurized milk or unvaccinated livestock was reported in 37 (69.8%). Fever was present in 64.6%, followed by arthralgia (49%), loss of appetite (42.3%), and weight loss (24.6%). Gastrointestinal symptoms were reported in 52.8% and included abdominal pain (34.6%), nausea (28.3%), vomiting (24.5%), and diarrhea (2.6%). Eight patients experienced pancytopenia (15.1%). The median length of intravenous antibiotic treatment was 7 days (range 3–14 days) and for oral antibiotic treatment 6 weeks (range 2–24 weeks). Most patients were initially treated with intravenous gentamycin (90.5%) and long-term oral antibiotics, most commonly doxycycline. Two (3.7%) required admission to the pediatric intensive care unit. No mortality was documented, and all cases of relapses were successfully treated.
Conclusions: Pediatric brucellosis is an acute febrile disease often associated with rheumatologic complaints. Patients 8–18 years of age also presented with headache, weight loss, and night sweats.

Background: Among the most frequent complications following transcatheter aortic valve replacement (TAVR) is hemostasis imbalance that presents either as thromboembolic or bleeding. Deviations in platelet count (PC) and mean platelet volume (MPV) are markers of hemostasis imbalance.
Objectives: To determine the predictive value of pre- and post-procedural PC and MPV fL 1-year all-cause mortality in patients who underwent TAVR.
Methods: In this population-based study, we included 236 TAVR patients treated at the Tzafon Medical Center between 1 June 2015 and 31 August 2018. Routine blood samples for serum PC levels and MPV fL were taken just before the TAVR and 24-hour post-TAVR. We used backward regression models to evaluate the predictive value of PC and MPV in all-cause mortality in TAVR patients.
Results: In this study cohort, MPV levels 24-hour post-TAVR that were greater than the cohort median of 9 fL (interquartile range 8.5–9.8) were the strongest predictor of 1-year mortality (hazard ratio 1.343, 95% confidence interval 1.059–1.703, P-value 0.015). A statistically significant relationship was seen in the unadjusted regression model as well as after the adjustment for clinical variables.
Conclusions: Serum MPV levels fL 24-hour post-procedure were found to be meaningful markers in predicting 1-year all-cause mortality in patients after TAVR.

Background: The parasympathetic system and its main neurotransmitter, acetylcholine, contributes to homeostasis of inflammation. Cholinergic dysregulation is thought to contribute to the pathogenesis of inflammatory rheumatic diseases. Cholinesterase activity in patients with psoriatic arthritis (PsA) has not been investigated.
Objectives: To compare the cholinesterase activity in patients with PsA and immunocompetent controls and to explore the correlation between cholinergic status (CS) and PsA disease activity.
Methods: Serum acetylcholinesterase (AChE) and total cholinesterase activity were measured in patients with PsA (n=88) and matched controls (n=84). Cholinergic activity before and 3–6 months after the initiation of a biologic treatment was evaluated in seven patients with PsA.
Results: The levels of AChE and CS were similar in both PsA patients and controls. PsA patients treated with biologics had significantly lower levels of AChE and CS compared to patients treated with non-biologics: 447.4 vs. 526 substrate hydrolyzed/min/ml, P = 0.005, and 1360.9 vs. 1536, P = 0.029, respectively. We found an association between C-reactive protein levels, AChE activity (r = 0.291, P = 0.008), and cholinergic status (r = 0.247, P = 0.026) in patients with PsA but not in controls. No correlation between AChE activity, cholinergic status, and the indices of PsA disease activity was found. After initiating or switching biologic treatment in 7 patients, AChE levels remained stable.
Conclusions: We demonstrated similar cholinesterase activity in patients with psoriatic arthritis and controls, highlighting a potential effect of biologic treatment on cholinergic activity in patients with PsA.

Background: Jejunal disease is associated with worse prognosis in Crohn's disease. The added value of diffusion weighted imaging for evaluating jejunal inflammation related to Crohn's Disease is scarce.
Objectives: To compare diffusion weighted imaging, video capsule endoscopy, and inflammatory biomarkers in the assessment of Crohn's disease involving the jejunum.
Methods: Crohn's disease patients in clinical remission were prospectively recruited and underwent magnetic resonance (MR)-enterography and video capsule endoscopy. C-reactive protein and fecal-calprotectin levels were obtained. MR-enterography images were evaluated for restricted diffusion, and apparent diffusion coefficient values were measured. The video capsule endoscopy-based Lewis score was calculated. Associations between diffusion weighted imaging, apparent diffusion coefficient, Lewis score, and inflammatory biomarkers were evaluated.
Results: The study included 51 patients, and 27/51 (52.9%) with video capsule endoscopies showed jejunal mucosal inflammation. Sensitivity and specificity of restricted diffusion for video capsule endoscopy mucosal inflammation were 59.3% and 37.5% for the first reader, and 66.7% and 37.5% for the second reader, respectively. Diffusion weighted imaging was not statistically associated with jejunal video capsule endoscopy inflammation (P = 0.813).
Conclusions: Diffusion weighted imaging was not an effective test for evaluation of jejunal inflammation as seen by video capsule endoscopy in patients with quiescent Crohn's disease.
