Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive, soft-tissue sarcoma. The treatment is surgical and includes wide local excision (WLE) or Mohs micrographic Surgery (MMS). There is no consensus regarding the preferred type of surgery.

Objectives: To compare the outcomes of the two types of surgery (WLE and MMS).

Methods: This retrospective cohort study was based on the medical records of 59 patients with DFSP treated at Sheba Medical Center (using the WLE method) or Assuta Medical Center (using the MMS method) between 1995 and 2018. The data included demographics, clinical presentations, imaging, types of wound closures, pathological margin status, surgical defect sizes, recurrences, and follow-up.

Results: Of the 59 included patients, 18 (30.5%) underwent WLE and 41 (69.5%) underwent MMS. The mean age at diagnosis was 40.1 ± 14.4 years. The male-to-female ratio was 1.5:1. The main tumor location was the trunk (50% for WLE and 41.5% for MMS). The main type of closure for both procedures was primary closure. In 72.2% of WLE and 78.8% of MMS cases, the margins were free. The difference between the final surgical defect and the original tumor size was statistically significantly smaller in patients who underwent MMS. The median duration of follow-up was 6.6 years. There was no significant difference in the rate of recurrence.

Conclusions: MMS enables better tissue preservation and results in a minor surgical defect compared to WLE, with no difference in tumor recurrence between the two methods.

Background: Allergic rhinitis (AR) is a common illness. Worldwide prevalence varies between 5% and 50% depending on self-reported surveys, test-based studies, geographic location, and age. Despite the clinical relevance of AR in the Israeli population, few studies have characterized the sensitization profiles and key pollen aeroallergen.

Objectives: To describe the most common aeroallergens eliciting a positive skin prick test (SPT) in AR patients across three different main climate zones in Israel.

Methods: We evaluated SPT of aeroallergen sensitization in 1308 AR patients from three topographically and climatically different areas of Israel, describing humidity levels, temperature, and urbanization.

Results: The overall prevalence of positive SPT among patients presenting with AR symptoms was 86%. Indoor aeroallergen sensitization was observed in 76% of patients. Monosensitization was noted in 20% of patients, and polysensitization was noted in 65%. Among the 1308 cases of AR, the top four aeroallergens were mites, olive tree pollen, grass pollen, and cat dander. The top aeroallergen in Israel's central district were mites (62%), olive tree pollen (36%), and grass pollen (30%). In the coastal plains, mites (92%), cat dander (36%), and olive tree pollen (33%) were most prevalent, and in the south mites (77%), olive tree pollen (30%), and grass pollens (26%) were most common.

Conclusions: The top four aeroallergens eliciting a positive SPT were mites, olive tree pollen, grass pollen, and cat dander. Identification of a major aeroallergen can tailor the allergist's SPT panels and specify which aeroallergen should be used for immunotherapy.

Background: Cardiac implantable electronic devices (CIEDs) with endocardial leads crossing the tricuspid valve can lead to or worsen tricuspid regurgitation (TR), causing substantial morbidity and mortality. Despite a recent randomized controlled study revealing a low short-term incidence of device-related TR (DRT) post-CIED implantation, uncertainties persist regarding the efficacy of intra-procedural 2-dimensional transthoracic echocardiography (2DTTE) in preventing long-term TR.

Objectives: To conduct a long-term follow-up study on patients with CIED implants based on a previous study conducted at our hospital.

Methods: In a retrospective study at Assuta Ashdod Medical Center (2018-2019), patients undergoing de-novo CIED implantation with (n=39, group 1) or without (n=51, group 2) intra-procedural 2DTTE were analyzed. Clinical, demographic, and long-term (> 1 year) echocardiographic data were collected and compared.

Results: The study included 90 patients (mean age 72.3 ± 11.0 years, 63% male, 23% ICD, 50% active leads, follow-up 32.8 ± 11 months). TR aggravation was found in 25% of patients (13 in group 1, 10 in group 2), with no statistical difference between groups. Multivariate analysis identified a history of atrial fibrillation (AF) as the sole significant factor in long-term TR deterioration (OR=3.44, 95%CI 1.13-10.43, P = 0.029). Other clinical, demographic, echocardiographic, and device-related factors did not significantly contribute to long-term DRT.

Conclusions: After one-year post-CIED implantation, the incidence of DRT significantly increases. Intra-procedural 2DTTE does not effectively reduce long-term DRT, suggesting that implantation-related mechanisms are less likely the primary cause. AF likely plays a major role in the pathogenesis of long-term TR in this subset post-CIED implantation.
