Background: With advances in myelodysplastic syndromes (MDS), patient cohorts from different time periods might be different.

Objectives: To compare presentation and outcomes between two cohorts.

Methods: Data were collected from George Washington University Medical Center, Washington, DC, USA 1986–1987 (DC), and Tel Aviv Medical Center, Israel 1999–2009 (TA).

Results: The study comprised 227 patients (139 TA, 88 DC). TA patients were older (75.4 ± 9.8 vs. 63.8 ± 14.3 years, P < 0.001) and had more cardiovascular diseases (56.8% vs. 14.8%, P < 0.001), fewer cytopenias (1.67 ± 0.82 vs. 2.0 ± 0.93, P = 0.003), and lower mean corpuscular volume (94.3 ± 9.9 fl vs. 100.5 ± 15.3 fl, P < 0.001). Hemoglobin, leukocyte, neutrophil, and platelet counts were similar. More TA patients had dysplasias. Bone marrow cellularity and cytogenetics were similar, but more TA patients had blasts < 5% (73.4% vs. 50.6%, P = 0.003). More TA patients had early French-American-British (FAB) disease (66.9% vs. 40.9%, P < 0.001) and lower risk disease per International Prognostic Scoring System (81% vs. 50%, P < 0.001). The 5 year survival (5YS) of TA patients was not significantly greater (62% vs. 55%). 5YS by FAB was also slightly greater for TA patients (77% vs. 65% for early FAB; 43% vs. 37% for advanced FAB, P > 0.05).

Conclusions: Although patients diagnosed with MDS at a later period were older and had more cardiovascular co-morbidities, they had fewer cytopenias, tended to have earlier disease, and had minimally greater, but not significant, 5YS.

Background: Contemporary data on clinical profiles and long-term outcomes of young adults with coronary artery disease (CAD) are limited.

Objectives: To determine the risk profile, presentation, and outcomes of young adults undergoing coronary angiography.

Methods: A retrospective analysis (2000–2017) of patients aged ≤ 35 years undergoing angiography for evaluation and/or treatment of CAD was conducted.

Results: Coronary angiography was performed in 108 patients (88% males): 67 acute coronary syndrome (ACS) and 41 non-ACS chest pain syndromes. Risk factors were similar: dyslipidemia (69%), positive family history (64%), smoking (61%), obesity (39%), hypertension (32%), and diabetes (22%). Eight of the ACS patients (12%) and 29 of the non-ACS (71%) had normal coronary arteries without subsequent cardiac events. Of the 71 with angiographic evidence of CAD, long-term outcomes (114 ± 60 months) were similar in ACS compared to non-ACS presentations: revascularization 41% vs. 58%, myocardial infarction 32% vs. 33%, and all-cause death 8.5% vs. 8.3%. Familial hypercholesterolemia (FH) was diagnosed in 25% of those with CAD, with higher rates of myocardial infarction (adjusted hazard ratio [HR] 2.62, 95% confidence interval [95%CI] 1.15–5.99) and revascularization (HR 4.30, 95%CI 2.01–9.18) during follow-up. Only 17% of patients with CAD attained a low-density lipoprotein cholesterol treatment goal < 70 mg/dl.

Conclusions: CAD in young adults is associated with marked burden of traditional risk factors and high rates of future adverse cardiac events, regardless of acuity of presentation, especially in patients with FH, emphasizing the importance of detecting cardiovascular risk factors and addressing atherosclerosis at young age.

Background: Nail-patella syndrome (NPS) is characterized by changes in the nails, knees, and elbows, as well as the presence of iliac horns detected by X-ray of the pelvis. A higher occurrence of psychiatric disorders has also been suggested in NPS. Heterozygous mutations in the gene encoding the LIM-homeodomain transcription factor (LMX1B) are identified in most patients with typical clinical findings of NPS.

Objective: To report on the association between NPS and schizophrenia.

Methods: Genomic DNA were isolated from a patient's venous blood and collected on ethylenediaminetetraacetic 5% with the Gentra Puregene Blood Kit. All exons and flanking regions of the LMX1B gene (LMX1B: NM_001174146.1) were amplified by standard polymerase chain reaction and analyzed by direct DNA sequencing with BigDye Terminators on an ABI 3100 sequencer. Sequence chromatograms were analyzed using SeqScape software version 1.1. Mutation analysis and characterization of variants was performed with the Alamut Software Version 2.1.

Results: We report a patient presenting to the psychiatry department with schizophrenia. Clinical examination revealed characteristic findings consistent with NPS. Since NPS was suspected, based on clinical findings, sequencing of all coding exons of LMX1B gene was completed. Results revealed a novel heterozygous mutation in the proband: c.546_547insACCG(het); p.Glu183Thrfs*11.

Conclusions: Based on LMX1B expression in brain regions that are implicated in neuropsychiatric illness, and especially in the development of dopaminergic neurons, we hypothesize that schizophrenia may be part of the clinical spectrum of NPS.

Background: A patient`s individual chance of being diagnosed with cardiovascular disease can be determined by risk scores.

Objectives: To determine the risk score profiles of patients presenting with a first acute coronary event according to pre-admission risk factors and to evaluate its association with long-term mortality.

Methods: The research was based on a retrospective study of a cohort from the 2010 and 2013 Acute Coronary Syndrome Israeli Surveys (ACSIS). Inclusion criteria included first event and no history of coronary heart disease or cardiovascular disease risk equivalent. The Framingham Risk Score, the European Systematic COronary Risk Evaluation (SCORE), and the American College of Cardiology/American Heart Association/ (ACC/AHA) risk calculator were computed for each patient. The risk profile of each patients was determined by the three scores. The prognostic value of each score for 5 year survival was evaluated.

Results: The study population comprised 1338 patients enrolled in the prospective ACSIS survey. The ACC/AHA score was the most accurate in identifying patients as high risk based on pre-admission risk factors (73% of the subjects). The Framingham algorithm identified 53%, whereas SCORE recognized only 4%. After multivariate adjustment for clinical factors at presentation, we found that no scores were independently associated with 5 year mortality following the first acute coronary event.

Conclusions: Patients with first acute coronary event had a higher pre-admission risk scores according to the ACC/AHA risk algorithm. No risk scores were independently associated with 5 year survival after an event.

Delusional parasitosis (DP) is a somatic type of delusional disorder, usually mono-symptomatic, in which the patients are convinced they are being infested with animal parasites while no objective evidence exists to support this belief. The complaints are usually about skin infestation, but involvement of the gastrointestinal tract has also been described. Numerous samples are brought for examination from skin, clothes, and environmental sources, while a detailed description of the “parasite” is given. In primary DP, the delusion arises spontaneously as a mono-delusional disorder, while in secondary DP, the delusional disorder arises secondary to another major medical, neurological, or psychiatric disorder. Practically all patients refuse psychiatric help. Shared psychotic disorder – folie à deux – is a known mode of presentation in delusional parasitosis. More than one member within a family may experience the same delusional state. For diagnosis and treatment of DP, a close collaboration among dermatologists, psychiatrists, and parasitologists is essential. Patients whose delusion of parasitosis is not severe can sometimes be relieved of their symptoms by establishing a reliable and meaningful therapeutic relationship. Symptomatic medication may be prescribed for the relief of pruritus, pain, and other symptoms. In more severe cases, such patients should be treated with psychopharmacological agents.

Background: Williams syndrome (WS) is a neurogenetic syndrome characterized by a variety of medical conditions and cognitive deficits along with distinct psychiatric and behavioral characteristics. To the best of our knowledge, no studies to date have comprehensively reported the prevalence of medical, cognitive deficits, and psychiatric disorders in one cohort of people with WS in one study.

Objectives: To detail the prevalence of the various clinical features of WS in a large nationwide Israeli cohort. To examine potential risk factors for attention deficit hyperactivity disorder (ADHD) in WS.

Methods: We investigated the effects of cardiovascular anomalies, intellectual quotient (IQ), and phonophobia (fear of sounds) on the likelihood of ADHD. The study included 80 participants with WS (mean age 7.76 years). Relevant medical information from medical records was obtained retrospectively. In addition, IQ testing and psychiatric assessments using structured tools were conducted. The association between ADHD and cardiovascular anomalies, IQ, and phonophobia was analyzed using a logistic regression.

Results: Supravalvular aortic stenosis and supravalvular pulmonary stenosis are the prevalent cardiovascular anomaly in WS. Phonophobia and ADHD are the most prevalent psychiatric diagnoses in people with WS. Phonophobia was significantly associated with the risk for ADHD in WS participants.

Conclusions: Our findings regarding the type and prevalence of medical, cognitive, and psychiatric characteristics in WS correspond to results in previous publications. We also showed a potential link between phonophobia and ADHD that merits further research.

Background: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE).

Objectives: To conduct the first nationwide survey focused on BrS patients with documented AE.

Methods: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2).

Results: The cohort comprised 31 patients: 25 in group 1, 6 in group 2. Group 1: 96% male, mean CA age 38 years (range 13–84). Nine patients (36%) presented with arrhythmic storm and three had a lethal outcome; 17 (68%) had spontaneous type 1 Brugada electrocardiography (ECG). An electrophysiology study (EPS) was performed on 11 patients with inducible ventricular fibrillation (VF) in 10, which was prevented by quinidine in 9/10 patients. During follow-up (143 ± 119 months) eight patients experienced appropriate shocks, none while on quinidine. Group 2: all male, age 30–53 years; 4/6 patients had familial history of sudden death age < 50 years. Five patients had spontaneous type 1 Brugada ECG and four were asymptomatic at ICD implantation. EPS was performed in four patients with inducible VF in three. During long-term follow-up, five patients received ≥ 1 appropriate shocks, one had ATP for sustained VT (none taking quinidine). No AE recurred in patients subsequently treated with quinidine.

Conclusions: CA from BrS is apparently a rare occurrence on a national scale and no AE occurred in any patient treated with quinidine.

Background: Eosinophilic fasciitis (EF) is a rare disease characterized by scleroderma-like skin, inflammation of deep muscle fascia, hypergammaglobulinemia, peripheral eosinophilia, and elevated erythrocyte sedimentation rate.

Objectives: To present our experience in diagnosis and treatment of seven biopsy-proven EF patients in a large tertiary medical center.

Methods: We screened all patients who were admitted to our tertiary medical center and diagnosed with EF by tissue biopsies from January 2000 to January 2016. We analyzed relevant patient files regarding diagnosis, treatment, and outcome parameters. A comprehensive framework was presented based on the results of our observations and the corresponding literature.

Results: We identified seven patients (six males; one child). Mean age at diagnosis was 37.4 years (range 10–67 years). Underlying autoimmune disorders were observed in three patients (42.8 %). Disease anatomical distribution was noted in lower and upper limbs (85.7% and 57.1%, respectively) as well as neck and shoulders (14.3% each). Three patients (42.8%) had a history of initial misdiagnosis. The mean time period from first clinical presentation to histopathological diagnosis was 150.3 days (range 16–602 days). Treatment included oral glucocorticoids (71.4%), pulse methylprednisolone (14.2%), and methotrexate (42.8%). Recovery from symptoms related to EF was observed in six patients.

Conclusions: Diagnosis of EF is primarily based on clinical and histopathological findings. As eradication of this disease can be expedited with early treatment, it is important to increase awareness in the medical community.
