Background: Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory skin disease associated with a heavy burden of morbidity and cost.

Objectives: To provide standardized estimates of trends in HS incidence and prevalence among patients in Israel between 2016 and 2019.

Methods: We conducted a population-based analysis of routinely collected electronic health records data from Clalit Health Services, the largest nationwide public health service provider in Israel. Age- and sex-adjusted rates were reported by using the standard European population as a reference.

Results: The study included 3488 HS incident cases. The mean ± SD age of onset was 30.3 years and was similar in males and females. HS was more common among Jews with low and medium socioeconomic status. The annual HS incidence rate increased throughout the study period. HS prevalence increased from 0.12% in 2016 to 0.17% in 2019.

Conclusions: HS prevalence and incidence rates steadily rose among the Israeli population between 2016 and 2019. Awareness of these findings can help provide an optimal allocation of healthcare resources by policymakers and health service providers and prevent delays in diagnosis.

Neuroendocrine tumors (NETs) are a group of rare, heterogenous neoplasms that maintain unique morphologic and clinical features of neuroendocrine neoplasia and account for approximately 0.5% of all newly diagnosed malignancies. NETs are divided into two groups based on their histopathological morphology: well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Well differentiated NETs are classified as G1, G2, or G3 based on their proliferation rate, whereas NECs are highly proliferative and poorly differentiated by definition [1]. Neuroendocrine neoplasms can occur almost anywhere in the body; however, they are most often seen in the gastrointestinal tract, pancreas, and lungs [2]. The extrahepatic bile duct is one of the rarest primary sites for NETs, accounting for 0.1% to 0.2% of NETs of the gastrointestinal tract [3]. Signet ring cell bile duct NETs are extremely uncommon and have no established incidence and prognosis due to their rarity. There is sparse information available regarding these tumors, and only a few cases have been reported in the literature to date. In this report, we presented the clinical course and surgical management of a 31-year-old female patient with a Klatskin signet ring cell NET.

In this study, we analyzed computed tomography (CT) radiological findings from trauma treated at a single hospital in the aftermath of the terror attack in Israel on 7 October 2023. The study includes images from 34 consecutive patients, consisting of 33 males and 1 female, ranging in age from 19 to 68 years. The majority of these patients underwent both chest-abdominal-pelvic (76%) and head and neck CT scans (64.7%). Key findings highlight a high incidence of head and neck injuries (55.9%), chest trauma (44.1%), and various injuries such as soft tissue lacerations (100%), fractures particularly skull fractures at 32.4%, and brain hemorrhages (23.5%). The limitations of this study include its single-center scope and the focus on stable patients, which may bias the representation of injury types. This case series provides critical insights into the radiological impacts of large-scale terror events, emphasizing the importance of comprehensive preparedness and research in the field of mass-casualty incident response.

Background: Solid organ transplant recipients (SOTRs) are at increased risk for both skin and internal malignancies (IM). The risk of IM after the occurrence of non-melanoma skin cancer (NMSC) has been studied in the general population but very little is known about this association in SOTRs.

Objectives: To evaluate the risk of IM following a prior diagnosis of post transplantation NMSC in SOTRs.

Methods: This single center retrospective cohort study included a study population of 329 SOTRs from Rabin Medical Center who had a post-transplant diagnosis of skin malignancy, internal malignancy, or both from 2012 to 2018.

Results: In total, 135 (41.03%) SOTRs were diagnosed with IM without a preceding diagnosis of NMSC while only 42 (12.76%) patients diagnosed with IM had a preceding diagnosis of NMSC. SOTRs with a diagnosis of NMSC showed a significantly decreased risk of developing subsequent IM (hazard ratio [HR] 0.64, 95% confidence interval [95%CI] 0.44–0.94, P = 0.02) compared to those without a prior NMSC diagnosis. Liver and lung transplant patients showed a significantly decreased risk of developing subsequent IM after a diagnosis of NMSC (HR 0.09 and 0.43, respectively). When stratified by type of IM, only patients who were diagnosed with a hematological malignancy had a significantly lower risk of developing this malignancy if they had a prior NMSC (HR 0.26).

Conclusions: The findings of this study suggest a protective effect of NMSC on subsequent IM in the organ transplant population.

Background: Infants born very prematurely have functionally and structurally immature gastrointestinal tracts.

Objectives: To assess the safety and tolerability of administration of enteral recombinant human (rh) insulin on formula fed preterm infants and to assess whether enteral administration of rh-insulin enhances gastrointestinal tract maturation by reducing the time to reach full enteral feeding.

Methods: A phase 2, multicenter, double-blind, placebo-controlled, randomized study was conducted. Premature infants (26–33 weeks gestation) were randomized 1:1 to receive insulin 400 μU/ml mixed with enteral feeding or placebo added to their formula. The primary efficacy outcome measure was the number of days required to achieve full enteral feeding. Safety outcomes included adverse events and blood glucose levels.

Results: The study consisted of 33 infants randomized for the safety population and 31 for efficacy analysis. The mean time to full enteral feeding was 6.37 days (95% confidence interval [95%CI] 4.59–8.15) in the enteral rh-insulin treatment group (n=16) and 8.00 days (95%CI 6.20–9.80) in the placebo group (n=15), which represents a statistically significant reduction of 1.63 days (95%CI 0.29–2.97; P = 0.023). There was no difference in blood glucose levels between the groups and none of the participants experienced hypoglycemia. Adverse events occurred in 9/17 (53%) infants in the enteral rh-insulin group and 12/16 (75%) in the placebo group.

Conclusions: Our trial demonstrated that administration of enteral rh-insulin as supplement to enteral nutrition significantly reduced time to achieve full enteral feeding in preterm infants with a gestational age of 26–33 weeks.

Background: The coronavirus disease-2019 (COVID-19) pandemic forced drastic changes in all layers of life. Social distancing and lockdown drove the educational system to uncharted territories at an accelerated pace, leaving educators little time to adjust.

Objectives: To describe changes in teaching during the first phase of the COVID-19 pandemic.

Methods: We described the steps implemented at the Technion–Israel Institute of Technology Faculty of Medicine during the initial 4 months of the COVID-19 pandemic to preserve teaching and the academic ecosystem. 

Results: Several established methodologies, such as the flipped classroom and active learning, demonstrated effectiveness. In addition, we used creative methods to teach clinical medicine during the ban on bedside teaching and modified community engagement activities to meet COVID-19 induced community needs. 

Conclusions: The challenges and the lessons learned from teaching during the COVID-19 pandemic prompted us to adjust our teaching methods and curriculum using multiple online teaching methods and promoting self-learning. It also provided invaluable insights on our pedagogy and the teaching of medicine in the future with emphasis on students and faculty being part of the changes and adjustments in curriculum and teaching methods. However, personal interactions are essential to medical school education, as are laboratories, group simulations, and bedside teaching

Background: Patients with critical limb ischemia (CLI) involving the below-the-knee (BTK) arteries are at increased risk of limb loss. Despite improvement in endovascular modalities, it is still unclear whether an aggressive approach results in improved limb salvage.

Objectives: To assess whether an aggressive approach to BTK arterial disease results in improved limb salvage.

Methods: A comparative study of two groups was conducted. Group 1 included patients treated between 2012 and 2014, primarily with transfemoral angioplasty of the tibial arteries. Group 2 included patients treated between 2015–2019 with a wide array of endovascular modalities (stents, multiple tibial artery and pedal angioplasty, retrograde access). Primary endpoint was freedom from amputation at 4 years.

Results: A total of 529 BTK interventions were performed. Mean age was 71 ± 10.6 years, 382 (79%) were male. Patients in group 1 were less likely to be taking clopidogrel (66% vs. 83%, P < 0.01) and statins (72 % vs. 87%, P < 0.01). Several therapeutic modalities were used more often in group 2 than in group 1, including pedal angioplasty (24 vs. 43 %, P = 0.01), tibial and pedal retrograde access (0 vs. 10%, P = 0.01), and tibial stenting (3% vs. 25%, P = 0.01). Revascularization of two or more tibial arteries was performed at a higher rate in group 2 (54% vs. 50%, P = 0.45). Estimated freedom from amputation at 40 months follow-up was higher in group 2 (53% vs. 63%, P = 0.05).

Conclusions: An aggressive, multimodality approach in treating BTK arteries results in improved limb salvage.

Background: The incidence of gestational diabetes mellitus (GDM) is increasing in parallel to the worldwide obesity and type 2 diabetes pandemic. Both GDM and pre-gestational diabetes mellitus (PGDM) are associated with short- and long-term consequences in the offspring. There are few recent studies addressing outcomes of newborns born to women diagnosed with GDM and PGDM in Israel.

Objectives: To assess perinatal complications in offspring of women with GDM and PGDM.

Methods: The authors conducted a single-center retrospective case-control study of outcomes of all newborns whose mothers had been diagnosed with diabetes in pregnancy compared to randomly assigned controls born on the same date, whose mothers had no diabetes.

Results: In the study period 2015–2017, 526 mothers diagnosed with GDM or PGDM and their newborn infants were identified. The authors randomly assigned 526 control infants. The rate of women with diabetes in pregnancy was 5.0%. Mothers with GDM and PGDM had higher rates of pre-eclampsia, multiple pregnancies, and preterm deliveries. Mothers with PGDM had significantly higher rates of intrauterine fetal demise (4.3%), congenital anomalies (12.8%), and small-for-gestational-age neonates (10.6%) compared to controls (0%, 3.2%, and 4.2%, respectively, P < 0.001). The risks for preterm or cesarean delivery, large-for-gestational-age neonate, respiratory morbidity, hypoglycemia, and polycythemia were increased in offspring of mothers with diabetes, especially PGDM.

Conclusions: Despite all the advancements in prenatal care, diabetes in pregnancy, both PGDM and GDM, is still associated with significant morbidities and complications in offspring. Better preconception and inter-pregnancy care might reduce these risks

Background: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) is associated with decreased perioperative morbidity and mortality.

Objectives: To report the outcomes of EVAR among patients older than 80 years of age.

Methods: In this retrospective study, we reviewed patients older than 80 years of age who underwent elective EVAR at our institution between 2007 and 2017. The demographics, perioperative morbidity and mortality, and long-term results are reported.

Results: During the study period, 444 patients underwent elective EVAR for AAAs. Among them 128 patients (29%) were > 80 years of age. Mean age was 84 ± 3.4 (range 80–96) years, and 110 patients (86%) were male. The EVAR was technically successful in 127 patients (99%) and there were intraoperative mortalities. Within 30 days of the surgery, nine patients (7%) died. Major and minor adverse events occurred in 26 (20%) and 59 (46%) patients, respectively. Factors associated with increased risk of perioperative morbidity and mortality included chronic kidney disease, peripheral artery disease, and the existence of three or more co-morbidities.

Conclusions: EVAR in the elderly can be performed with a high rate of success; however, it is associated with a substantial rate of morbidity and mortality, particularly when patients present with multiple co-morbidities. When performing EVAR in this population group, the risk of rupture must be considered opposed to the life expectancy of these patients and the risk of perioperative morbidity and mortality.
