Background: Immunoglobulin G4-related disease (IgG4-RD) is a chronic, immune-mediated condition characterized by fibro-inflammatory lesions with lymphoplasmacytic infiltration. Diagnosis traditionally relies on histopathological findings, including the presence of IgG4+ plasma cells. However, due to challenges in biopsy accessibility, additional measures are needed to facilitate diagnosis.

Objectives: To identify additional parameters for characterizing IgG4-RD patients.

Methods: We compared several circulating factors between a cohort of patients with IgG4-RD disease seen at our hospital between 2017 and 2023 and healthy controls.

Results: Among 16 suspected patients, 13 were confirmed to have IgG4-RD, and 3 were classified as highly likely. Comparison with controls revealed differences in white blood cell count (WBC) (Folf change (FC) 1.46, P < 0.05), plasmablasts (FC 3.76, P< 0.05), plasmablasts CD38 (FC 1.43, P < 0.05), and CD27 (FC 0.66, P = 0.054), thus highlighting potential markers for IgG4-RD diagnosis. Treatments with steroids/rituximab tend to reduce plasmablast (FC 0.6) and IgG4 (FC 0.28) levels and to increase Gal-3 levels.

Conclusions: Levels of plasmablasts are a significant diagnostic feature in IgG4-RD. Healthy individuals have a lower level of plasmablasts. Elevated Gal-3 in serum of patients with IgG4-RD suggests a role in plasmablast activation. CD38/CD27 expression by plasmablasts emerges as a potential marker. Further research on a larger cohort is needed to confirm these findings.

Late arrival ST-segment elevation myocardial infarction (STEMI) is defined as a patient-related delay > 12 hours. It is estimated to represent a significant portion of STEMI patients. As reflected by society guidelines, this group of patients impose great therapeutic challenge, namely due to controversy in the literature regarding optimal care, together with major adverse clinical outcomes [1]. In addition to a possible myocardial infarction (MI), mechanical complications include ventricular septal defect (VSD), left ventricular (LV) free wall, or papillary muscle rupture. Prompt diagnosis and intervention are crucial to improve outcomes as post-infarction ventricular septal defect (PIVSD) carries a high mortality rate. We describe the successful management of a large VSD complicated by cardiogenic shock in a latecomer STEMI patient with complex coronary artery disease (CAD).

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease involving apocrine gland-bearing regions. There is an under-representation of non-Caucasians in epidemiologic studies of HS. The characteristics of HS in Israeli Arabs have not yet been studied.

Objectives: To investigate the demographic and clinical profile of HS in the Israeli Arab population.

Methods: A retrospective analysis was conducted in two cohorts of patients with HS in Israel. The patients were derived from the database of a large health management organization (n=4191, 639 Arabs; population-based) and a major tertiary medical center (n=372, 49 Arabs). Demographic and clinical data were compared between ethnic groups.

Results: The prevalence of HS in Israeli Arabs was found to be 0.5%, fivefold higher than in Jews. Arab patients were younger (35.3 vs. 40.5 years, P < 0.001) and mostly male (52% vs. 35.7%, p < 0.001), with lower rates of co-morbidities, including smoking (40.8% vs. 55.7%, p < 0.001), hyperlipidemia, and depression as well as a higher rate of dissecting cellulitis (10.2% vs. 1.9%, p = 0.008). HS was more severe in Arabs, but of shorter duration, with mainly axillary involvement (79.6% vs. 57.9%, p = 0.004). Treatment with hormones was more common in Jews, and with biologic agents in Arabs.

Conclusions: The findings suggest a different phenotype of HS in Arabs, warranting further study.

Background: Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics.

Objectives: To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora.

Methods: We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology.

Results: Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855).

Conclusions: Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.

Background: The prevalence of Group A streptococcus (GAS) carriage among adults is studied less than in children. The variability of reported carriage rates is considerably large and differs among diverse geographic areas and populations.

Objectives: To evaluate the prevalence of GAS carriage among adults in Israel.

Methods: In this prospective study, conducted in a large healthcare maintenance organization in Israel, we obtained pharyngeal cultures from adults attending the clinic without upper respiratory tract complaints or fever. Patient data included sex, age, number of children, and religious sectors.

Results: From May to December 2022, eight family physicians collected a total of 172 throat swabs (86% response rate). The median age was 37 years (range 18–65); 72.7% were females, 22.7% were ultra-Orthodox Jewish, and 69.2% had children. The prevalence of GAS carriage was 6.98%, 95% confidence interval (95%CI) 3.7%–11.9%. GAS carriers were younger (31.7 vs. 39.3 years, P = 0.046), and the majority were ultra-Orthodox Jews (58.3% vs. 20%, P = 0.006). All GAS carriers were from lower socioeconomic status. When assessing risk factors for GAS carriage using multivariate analysis, only being an ultra-Orthodox Jew was positively related to GAS carriage (adjusted odds ratio 5.6, 95%CI 1.67–18.8).

Conclusion: Being an ultra-Orthodox Jew was the single variable associated with a GAS carriage, which may be related to having many children at home and living in overcrowded areas. Primary care physicians in Israel should recognize this situation when examining patients with sore throats, mainly ultra-Orthodox Jews.

Takotsubo syndrome (TTS) or Takotsubo cardiomyopathy (TCM) is a cardiomyopathy that develops rapidly and is usually caused by mental or physical stress. It is usually a transient cardiomyopathy. The presumed cause of the onset of the syndrome is the increase and extreme secretion of adrenaline and norepinephrine due to extreme stress. An infectious disease such as sepsis can also be the cause [1].

One of the most widespread diagnostic tools is the revised version of Mayo Clinic Diagnostic Criteria for TTS (2008) [2], which incorporates transient wall-motion abnormalities, absence of a potential coronary culprit, myocarditis, and pheochromocytoma. The prognosis for TTS is usually favorable and resolves with complete recovery in 4–8 weeks in more than 90% of patients.

The ancient, Biblical, holy Ten Commandments were presented to humanity to serve as guidelines for relationships between individuals and the deity they worship as well as a benchmark for living in civilized communities, irrespective of religious affiliation. The commandments are also embedded in medical education taught to medical students and other health professions throughout the world. Thus, the Ten Commandments are embedded in the medical communications curriculum at Adelson School of Medicine, Ariel University, Ariel, Israel. Unfortunately, most of these commandments were desecrated during the violent, hostile, merciless, and ruthless attack inflicted by the Hamas terror organization on villages, rural communities, and cities in southern Israel on 7 October 2023. We define the Ten Commandments in terms of medical education and describe their desecration by Hamas terrorists before and during the Iron Swords war.

Background: The Gaza–Israeli conflict poses challenges for unbiased reporting due to its complexity and media bias. We explored recent scientific publications to understand scholarly discourse and potential biases surrounding this longstanding geopolitical issue.

Objectives: To conduct a descriptive bibliometric analysis of PubMed articles regarding the recent Gaza–Israeli conflict.

Methods: We reviewed 1628 publications using keywords and medical subject headings (MeSH) terms related to Gaza, Hamas, and Israel. We focused on articles written in English. A team of researchers assessed inclusion criteria, resolving disagreements through a third researcher.

Results: Among 37 publications, Lancet, BMJ, and Nature were prominent journals. Authors from 12 countries contributed, with variety of publication types (46% correspondence, 32% news). Pro-Gaza perspectives dominated (43.2%), surpassing pro-Israel (21.6%) and neutral (35.1%) viewpoints. Pro-Gaza articles exhibited higher Altmetric scores, indicating increased social media impact. Pro-Israel publications were predominantly authored by Israelis.

Conclusions: The prevalence of pro-Gaza perspectives underscores challenges in maintaining impartiality. Higher social media impact for pro-Gaza publications emphasizes the need for nuanced examination. Addressing bias is crucial for a comprehensive understanding of this complex conflict and promoting balanced reporting.

Higher potency bisphosphonates, typically intravenous formulations, are given at lower doses for postmenopausal women. The treatment has improved compliance compared to daily oral therapy. Since bisphosphonates are exclusively excreted via the kidneys, intravenous formulation has been associated with deterioration of renal function, specifically in the setting of preexisting renal disease or concomitant use of nephrotoxic agents [1].

Anti-tumor necrosis factor-alpha (anti-TNFα) medications are the most frequently used biologicals to treat inflammatory bowel disease (IBD). Little is known about the ocular side effects of this drug category. We present a case series of six young patients with Crohn disease (CD) and no previous ophthalmologic manifestations who developed blepharitis after commencing treatment with anti-TNFα therapy. Six otherwise healthy patients with CD, with no history of allergies or prior ocular complaints, developed blepharitis at a median of 7.5 months after the initiation of anti-TNFα therapy. All ophthalmic findings were treated topically. The ocular symptoms of two of the patients resolved shortly after discontinuation of the anti-TNFα treatment. The other four presented with relapsing-remitting symptoms. Blepharitis is a common ocular disease in the general population and an extra-intestinal manifestation in patients with IBD. It may be an adverse effect of anti-TNFα therapy in this patient population.

Background: Unfractionated heparin is the preferred anticoagulant used during open heart surgeries, including left ventricular assist device (LVAD) implantation. In cases in which patients are heparin-induced thrombocytopenia positive (HIT+), the accepted practice has been to substitute heparin with bivalirudin. This practice may be associated with significant bleeding and adverse outcomes.

Objectives: To review our experience with HIT+ patients who were heparin-induced thrombocytopenia with thrombosis negative (HITT-) and who underwent HeartMate 3 LVAD implantation using heparin intraoperatively rather than bivalirudin.

Methods: From 2016 to 2022, 144 adult patients were implanted with HeartMate 3 LVAD at our center. Among them, 7 were detected as HIT+ but HITT- and therefore were prescribed intraoperatively with heparin and treated pre- and postoperatively with bivalirudin. We reviewed the preoperative, intraoperative, and postoperative characteristics as well as short-term mortality and the complication rates of these HIT+ patients.

Results: The median age of our cohort was 56 years (51–60), 71% were male (n=5), all were INTERMACS Level 1, and most were bridged to transplant (n=6, 86%). The 30-day mortality rate post-implantation was 0%. The average 24-hour chest drain postoperative output was 1502.86 ± 931.34 ml. There were no intraoperative pump thromboses, perioperative thromboses, cerebrovascular accidents, or gastrointestinal bleeding within the first 24 hours postoperative. One patient required a revision due to bleeding.

Conclusions: Intraoperative unfractionated heparin may be administered to patients who are HIT+ and HITT- while undergoing LVAD implantation. However, further investigation is required.

Nocardia species are gram-positive aerobic bacteria, usually acquired by inhalation or traumatic percutaneous inoculation [1,2]. It is a rare opportunistic infection that mainly occurs in immunocompromised hosts, patients with human immunodeficiency virus (HIV), organ transplant recipients, and long-term corticosteroid treated patients [1,2]. It is associated with high morbidity and mortality rates. The increased use of tumor necrosis factor (TNF) inhibitors has been accompanied by increased risk of different opportunistic infections including reactivation of tuberculosis, viral hepatitis B and C, listeria, fungal and bacterial infections [3,4]. To date, there are scarce case reports regarding nocardial infection with anti-TNF, particularly during the first 6 months of treatment.

We present a case of nocardial tenosynovitis of the hand in a patient with psoriatic arthropathy who was followed in our rheumatology clinic in Meir medical center in Israel after treatment with an anti TNF therapy.

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: 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: Nasal obstruction is one of the most common complaints in the practice of rhinology.

Objective: To adapt the Nasal Obstruction Scale Evaluation (NOSE) questionnaire to Hebrew (H-NOSE) and to assess its sensitivity and specificity.

Methods: Candidates for surgical intervention due to isolated nasal obstruction and healthy volunteers (controls) were included in the validation. The English NOSE questionnaire was translated into Hebrew and re-translated for translation validity. Patients completed the H-NOSE questionnaire before and after surgery for nasal obstruction. The same questionnaire was completed by the controls. Test–retest reliability was performed within 2 weeks. Psychometric properties (reliability, reproducibility, validity, and responsiveness) were assessed by a test–retest procedure, internal consistency, correlation to the Hebrew Sino-Nasal Outcome Tool 22 (He-SNOT-22), and response sensitivity.

Results: In total, 179 patients with nasal obstruction and 74 controls completed the questionnaire. Cronbach's alpha score was 0.93 for internal consistency. The receiver operating characteristic curve demonstrated high sensitivity and specificity (< 90%) and area under the curve was 0.97. We found no significant difference in test–retest reliability. The difference between the pre- and postoperative questionnaire scores was highly significant (13.9 ± 4.0 vs. 3.2 ± 4.1, respectively, P < 0.001).

Conclusions: The H-NOSE questionnaire demonstrated reliable internal consistency, sensitivity, specificity, and reliability. The Hebrew version differentiated between patients and heathy controls and was easy to administer. This instrument is useful for Hebrew speaking patients who undergo surgery for nasal obstruction.
