IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition. Accumulated research and data since 2003 have increasingly affirmed its classification as a systemic disease. Although IgG4-RD generally presents with involvement of one or several organ systems, it can affect almost any organ. The disease manifests gradually with the development of tumor-like lesions.

Constitutional symptoms, such as systemic fever and elevated inflammatory markers, are generally absent in association with this pathological condition. However, it is common for patients to exhibit allergy characteristics in addition to a slight increase in peripheral blood eosinophilia. The clinical manifestations of the disease exhibit variability on the specific organ system affected. Specific involvement of organs can ultimately result in organ failure. For example, retroperitoneal fibrosis commonly leads to post-renal failure [1]. The 2020 Revised Comprehensive Diagnostic (RCD) criteria for IgG4-RD include three components for diagnosis: clinical and radiological components (1), serological diagnosis (2), and unique pathological diagnosis (3). When all three are present it is a definitive diagnosis. The presence of components 1 + 3 constitutes a probable diagnosis, while the presence of components 1 + 2 indicates possible diagnosis [2].

Testicular involvement of IgG4-RD has been described in a few case reports. However, the uniqueness of our case is the manifestation of a testicular mass as a different target organ of relapse in a patient in remission from retroperitoneal fibrosis.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1-RA) are new antidiabetic drugs that are recommended by current guidelines as a class I novel glucose-lowering treatment that improves cardiovascular outcome in type 2 diabetes mellitus (T2DM), particularly in patients with cardiovascular disease.

Objectives: To evaluate adherence to the current guidelines for treatment with SGLT2i and GLP1-RA drugs in patients referred to ambulatory consultant cardiology clinics with pre-existing T2DM.

Methods: We studied consecutive new patients with a pre-existing diagnosis of T2DM who were referred to the Clalit Health Services ambulatory consultant cardiology clinic over a 6-month period. The recorded information included demographics, co-morbidities, and prescribed drugs at patient admission.

Results: During the study period, 1782 patients visited our outpatient cardiology clinic. At screening, T2DM was present in 428 patients (24%); 77 (18%) were being treated with SGLT2i, and 39 (9.1%) with GLP1-RA. Patients receiving SGLT2i and GLP1-RA were younger and had more coronary artery disease, lower mean left ventricular ejection fraction, and higher mean estimated glomerular filtration rates than those who were not receiving these drugs. HbA1C was > 7 in 205 (47.9%) patients and > 7.5 in 136 patients (31.8%). Body mass index was > 30 kg/m² in 231 (54%) patients.

Conclusions: GLP1-RA and SGLT2i drugs were found to be administered more frequently than previously reported, but they are not yet satisfactorily prescribed.

Background: Patients admitted to the hospital after successful resuscitation from sudden cardiac death (SCD) are treated with therapeutic hypothermia (TH) to facilitate brain preservation. The prognostic significance of J (Osborn) waves (JOW) in the 12 leads electrocardiogram in this setting has not been elucidated as yet.

Objectives: To ascertain retrospectively the prognostic significance of JOW recorded during TH in SCD survivors.

Methods: The study comprised 55 consecutive patients who underwent TH. All patients achieved a core temperature of 33°C at the time of electrocardiogram analysis. We compared 33 patients with JOW to 22 patients without JOW. The endpoints were in-hospital, long-term all-cause mortality, and irreversible anoxic brain injury (IABI).

Results: Patients with JOW compared to patients without JOW were younger (55.1 ± 11.6 vs. 64.5 ± 11.7 years, respectively, P < 0.006), with a lower incidence of hypertension (52% vs. 86%, P < 0.007), diabetes mellitus (15% vs. 50%, P < 0.005), and congestive heart failure (15% vs. 45%, P < 0.013). In-hospital and long-term mortality were significantly higher in patients without JOW (86% vs. 21%, 91% vs. 24%, respectively, P < 0.000001). Among patients without JOW who survived hospitalization, 66.7% presented with IABI versus 7.7% of the patients with JOW (P < 0.0001). In multivariate analysis, the absence of JOW was a significant predictor for poor prognosis.

Conclusions: The absence of J (Osborn) waves on electrocardiograms obtained during TH is associated with poor prognosis among SCD survivors

Background: The cold season seems to be a trigger for atrial fibrillation (AF). Some reports are controversial and demonstrate variability according to the climatic characteristics in different regions.

Objective: To analyze whether meteorological factors contribute to seasonal variation of exacerbation of AF diagnosed in patients referred to the emergency department (ED) of our hospital.

Methods: We retrospectively reviewed medical data of consecutive patients admitted to the ED with symptomatic acute onset AF from 1 January 2016 to 31 December 2018. We recorded the mean monthly outdoor temperature, barometric pressure, and relative humidity during the study period.

Results: During the study period, 1492 episodes of AF were recorded. New onset AF were 639 (42.8%) and paroxysmal atrial fibrillation (PAF) were 853 (57.2%) (P = 0.03). The number of overall admission of AF episodes was not distributed uniformly through the year. Incidence of AF episodes peaked during December and was lowest in June (P = 0.049). Of 696 episodes (46.6 %) the patients were hospitalized and for 796 (53.4%) the patients were discharged (0.01). The number of hospitalizations was not distributed uniformly through the year (P = 0.049). The highest number of hospitalizations happened in December and the lowest in May. Outdoor temperature and barometric pressure (but not relative humidity) may mediate a monthly fluctuation in AF episodes with highest number of ED visits in December and the lowest in June.

Conclusions: Meteorological conditions influence exacerbation of AF episodes and hospitalization. Outdoor temperature and barometric pressure may mediate a monthly fluctuation in AF

Background: Survival of patients who were discharged from the hospital following out-of-hospital cardiac arrest (OHCA) has not been well defined.

Objective: To verify predictor variables for prognosis of patients following OHCA who survived hospitalization.

Methods: We retrospectively reviewed clinical, demographic, and outcome data of consecutive patients who were hospitalized from January 1, 2009, through December 31, 2014, into the intensive coronary care unit (ICCU) after aborted OHCA and discharged alive. The patients were followed until December 31, 2015.

Results: Of the 180 patients who were admitted into ICCU after OHCA, 64 were discharged alive (59.3%): 55 were male (85.9%), 14 died 16.5 ± 18 months after their discharge. During 1 year follow-up, nine patients (14.1%) died after a median period of 5.5 months and 55 patients (85.9 %) survived. Diabetes mellitus and chronic renal failure (CRF) were more frequent in patients who died within 1 year after their hospital discharge than those who survived. Ventricular fibrillation, such as initial arrhythmia, and opening of occluded infarct related artery were more frequent in survivors.

Conclusions: Most of the patients who were discharged after OHCA were alive at the 1 year follow-up. The risk of death of cardiac arrest survivors is greatest during the first year after discharge. CRF remains a poor long-term prognostic factor beyond the patients' discharge. Ventricular fibrillation, as initial arrhythmia, and opening of occluded infarct related artery have a positive impact on long-term survival.

A flowering plant of variegated ingredients and psychoactive qualities, cannabis has long been used for medicinal and recreational purposes. Currently, cannabis is approved in several countries for indications of symptomatic alleviation. However, limited knowledge on the benefits and risks precludes inclusion of cannabis in standard treatment guidelines. This review provides a summary of the available literature on the use of cannabis and cannabinoid-based medicines in palliative oncology. Favorable outcomes are demonstrated for chemotherapy-induced nausea and vomiting and cancer-related pain, with evidence of advantageous neurological interactions. Benefit in the treatment of anorexia, insomnia and anxiety is also suggested. Short- and long-term side effects appear to be manageable and to subside after discontinuation of the drug. Finally, cannabinoids have shown anti-neoplastic effects in preclinical studies in a wide range of cancer cells and some animal models. Further research is needed before cannabis can become a part of evidence-based oncology practice.

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: The incidence of cardiovascular disease increases with age, and visits by elderly patients to the outpatient cardiac clinic are becoming more frequent.

Objectives: To characterize cardiovascular pathologies of patients 70 years of age and over who visit the outpatient cardiac clinic.

Methods: We investigated cardiovascular pathologies, risk factors, and medications in new patients over a 2 month period.

Results: The study population comprised 290 patients: 139 (47.9%) were older than 70 years. Among the cardiovascular pathologies, aortic stenosis, angina pectoris, congestive heart failure, s/p coronary artery bypass graft, and stroke were more frequent in the elderly patients than in those under age 70. Among the risk factors for ischemic heart disease, only hypertension was more frequent in the elderly population, whereas fewer in this group were active smokers. The mean number of medications administered was 3.51 ± 1.63 among the elderly patients compared to 1.99 ± 1.71 among the younger ones (P = 0.0001). Beta-blockers were the most frequently used cardiovascular drugs both in the elderly (59.7%) and in the younger patients (43%) (P = 0.0046).

Conclusions: Patients over age 70 represent about half the visits in our outpatient clinic. Their multiple cardiovascular pathologies and therapeutic requirements raise the issue of developing the cardiology service to meet the special needs of geriatric patients.
 

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.
