Backgrounds: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression.

Objectives: To evaluate the association between BD and depression, adjusting for established risk factors for depression.

Methods: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex.

Results: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37–2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39–2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18–39 years of age), low and high socioeconomical status, and non-smokers.

Conclusions: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Background: Fibromyalgia syndrome (FMS) is characterized by widespread musculoskeletal pain and tenderness with associated neuropsychological symptoms such as fatigue, unrefreshing sleep, cognitive dysfunction, anxiety, and depression. Osteoporosis is defined as a reduction of bone density. Previous studies to determine an association of FMS with osteoporosis showed mixed results, partially due to small sample sizes and lack of statistical power.

Objectives: To evaluate the association of FMS with osteoporosis.

Methods: We conducted a case-control study utilizing the database from Israel’s largest health maintenance organization. FMS patients were compared to age- and sex-matched controls. Data were analyzed using chi-square and t-tests. Multivariable logistic regression models assessed the association between osteoporosis and FMS. Spearman’s rho test was used for correlation.

Results: We utilized data from 14,296 FMS patients and 71,324 age- and sex-matched controls. Spearman's rho test showed a significant correlation between FMS and osteoporosis (correlation coefficient 0.55, P < 0.001). A logistic regression for osteoporosis showed an odds ratio [OR] of 1.94 (95% confidence interval [95%CI] 1.83–2.06, P < 0.001) for FMS compared to controls and found higher body mass index to be slight protective (OR 0.926, 95%CI 0.92–0.93, P < 0.001).

Conclusions: There is a significant correlation between FMS and osteoporosis. Early detection of predisposing factors for osteoporosis in FMS patients and implementation of suitable treatments and prevention measures (such as dietary supplements, resistance or weight bearing exercise, and bone-mineral enhancing pharmacological therapy) may reduce both occurrence rate and severity of osteoporosis and its complications, such as fractures.

Worldwide, students of healthcare professions attend clinical rotations at medical facilities. Much research, and consequently scientific publications, is produced during their studies, bearing the fruits of student–faculty collaboration. To the best of our knowledge, no previous contract has been proposed detailing the fine print to pre-determine mutual responsibilities and privileges of students and faculty. Our objective was to present such a contract to the relevant students and faculty. We conducted a literature review to study existing proposals and solutions for this dilemma. Appropriate guidelines were also scanned. We included a proposal for a standard contract as the basis for student–faculty agreement for conducting research and publishing collaborative work. Questions regarding the relative contribution of students and subsequent authorship often arise. Vague rules and absent regulations in this realm can, at times, can be disadvantageous to students. We foresee a future role for our proposed agreement.

Background: Rare incidence cases are part of the routine work of pediatric surgeons. Cecal anomalies in children are an example of such cases.

Objectives: To describe the presentation, workup, management and outcome of rare cecal anomalies in children and to analyze the skills needed for their successful treatment.

Methods: A retrospective chart review was conducted of all cases of cecal anomalies managed by the pediatric surgical service at a tertiary hospital from June 2017 to January 2020. Data regarding demographics, clinical presentation, radiological studies, surgical treatment, pathology, complications, and outcome were collected.

Results: Five cases of cecal anomalies were encountered over a period of 32 months, including a cecal volvulus, cecal duplication, cecal intussusception, and two cecal masses (one ulcerated lipoma and one polyp). All patients, except the patient with cecal duplication, presented acutely and were managed surgically. Long-term follow-up of 17–24 months was unremarkable in all cases.

Conclusions: A wide knowledge base, careful judgment, and creativity enable pediatric surgeons to successfully treat rare conditions such as rare cecal anomalies. These skills should be part of the education of pediatric surgery trainees.

Background: Hospitalization is an inherently serious event in the oldest-old, as the risk of complications associated with it increases exponentially with age and can lead to death. Despite the size of the problem, few studies have been dedicated to determining mortality predictors among hospitalized older patients, particularly among the oldest-old.

Objectives: To examine in-hospital mortality predictors in the oldest-old adults hospitalized in an acute geriatric ward.

Methods: We retrospectively surveyed electronic hospital health records of 977 elderly patients, aged ³ 90 years, admitted between January 2007 and December 2010 from the emergency department to the acute geriatrics department. We compared the characteristics of the patients who survived to those who died during the hospital stay.

Results: The patients mean age was 93.4 years. In-hospital mortality rate was about 11.6%. Mortality predictors were female sex, on-admission pneumonia, co-morbid congestive heart failure and cerebrovascular accident, high troponin I levels, lower levels of albumin, and higher level of urea (P = 0.032, P < 0.0001, P = 0.0015, P = 0.0049, P = 0.0503, P < 0.0001 and P < 0.0001, respectively). Consumption of ³ 5 drugs and the number of hospitalizations in the last year were inversely associated with death (P = 0.0145 and P < 0.0001, respectively).

Conclusions: Careful evaluation of mortality predictors might be useful for therapeutic planning and identification of potential inpatients for specific interventions. Awareness of in-hospital mortality predictors might contribute to reducing in-hospital death.

Background: Freeze dried plasma (FDP) is a commonly used replacement fluid in the prehospital setting when blood products are unavailable. It is normally administered via a peripheral intravenous (PIV) line. However, in severe casualties, when establishing a PIV is difficult, administration via intraosseous vascular access is a practical alternative, particularly under field conditions.

Objectives: To evaluate the indications and success rate of intraosseous administration of FDP in casualties treated by the Israel Defense Forces (IDF).

Methods: A retrospective analysis of data from the IDF-Trauma Registry was conducted. It included all casualties treated with FDP via intraosseous from 2013 to 2019 with additional data on the technical aspects of deployment collected from the caregivers of each case.

Results: Of 7223 casualties treated during the study period, intravascular access was attempted in 1744; intraosseous in 87 of those. FDP via intraosseous was attempted in 15 (0.86% of all casualties requiring intravascular access). The complication rate was 73% (11/15 of casualties). Complications were more frequent when the event included multiple casualties or when the injury included multiple organs. Of the 11 failed attempts, 5 were reported as due to slow flow of the FDP through the intraosseous apparatus. Complications in the remaining six were associated with deployment of the intraosseous device.

Conclusions: Administration of FDP via intraosseous access in the field requires a high skill level.

Background: Handheld ultrasound devices present an opportunity for prehospital sonographic assessment of trauma, even in the hands of novice operators commonly found in military, maritime, or other austere environments. However, the reliability of such point-of-care ultrasound (POCUS) examinations by novices is rightly questioned. A common strategy being examined to mitigate this reliability gap is remote mentoring by an expert.

Objectives: To assess the feasibility of utilizing POCUS in the hands of novice military or civilian emergency medicine service (EMS) providers, with and without the use of telementoring. To assess the mitigating or exacerbating effect telementoring may have on operator stress.

Methods: Thirty-seven inexperienced physicians and EMTs serving as first responders in military or civilian EMS were randomized to receive or not receive telementoring during three POCUS trials: live model, Simbionix trainer, and jugular phantom. Salivary cortisol was obtained before and after the trial. Heart rate variability monitoring was performed throughout the trial.

Results: There were no significant differences in clinical performance between the two groups. Iatrogenic complications of jugular venous catheterization were reduced by 26% in the telementored group (P < 0.001). Salivary cortisol levels dropped by 39% (P < 0.001) in the telementored group. Heart rate variability data also suggested mitigation of stress.

Conclusions: Telementoring of POCUS tasks was not found to improve performance by novices, but findings suggest that it may mitigate caregiver stress.

Background: Recent studies show a high risk of developing malignancy in patients with Fanconi anemia. The most common solid tumor in this condition is head and neck squamous cell carcinoma (HNSCC) and there is often uncertainty and about disease behavior as well as chemotherapy and radiation response.

Objectives: To describe and characterize HNSCC among Fanconi anemia patients on the Israeli Fanconi Registry

Methods: Our study population included patients in Israel's inherited bone marrow failure registry who were diagnosed with Fanconi anemia between1980 and 2016. Demographic, clinical, and laboratory data were collected from patient charts.

Results: From the collected data, HNSCC was confirmed in 6/111 (5.4%) Fanconi anemia patients; 1 (17%) had classic HNSCC risk factors of tobacco abuse and 4 (56%) had undergone primary surgery. The 3 (50%) receiving concurrent chemoradiotherapy had mild side effects, while half developed metachronous primary malignancy, and all developed > 2 primary malignancies. The overall median survival of the patients in our study was 14 (0.5–57) months.

Conclusions: Fanconi anemia patients have a very high risk of developing HNSCC. Proactive screening for malignancies is needed for the head and neck regions. We also found that chemoradiotherapy can be used safely in high-stage cancers.

Background: Diabetes mellitus (DM) is one of the risk factors for progression from latent to active tuberculosis. However, the effect of DM on subsequent tuberculosis treatment is still inconclusive.

Objectives: To compare tuberculosis treatment outcomes and the rate of drug resistance of tuberculosis patients with or without DM.

Methods: This case-control study was conducted between 2005 and 2015 at the only tuberculosis ward in Israel. All 80 tuberculosis patients who had DM and were hospitalized during the study period were included in this study, as were a randomized sample of 213 tuberculosis patients without DM. Demographic, clinical, and laboratory data were collected from patient files in the hospital and clinics after discharge.

Results: Tuberculosis patients with DM were more often older and more likely to be Israeli citizens with a lower socioeconomic status than patients without DM. No statistically significant differences were found in clinical presentation, radiological findings, and sputum smear tests between the two groups. Culture converting times were prolonged in patients with DM compared to normoglycemic patients. Multidrug drug resistance tuberculosis was more common among normoglycemic tuberculosis patients than tuberculosis patients with DM (9.2% vs. 1.6%, P = 0.12). Treatment success rates were 76.2% and 83.1% for tuberculosis patients with or without DM, respectively (P = 0.18). DM was not statistically significant in the multivariate analysis predicting treatment success, which controlled for age, citizenship, compliance, addictions, and chronic diseases.

Conclusions: The presence of DM does not necessarily affect tuberculosis treatment outcomes as long as treatment compliance is optimal.

Background: Laparoscopic removal of ovarian dermoid cysts has been associated with increased risk for recurrence.

Objectives: To investigate the risk factors associated with recurrence of dermoid cysts.

Methods: We conducted a retrospective review of all women who underwent cystectomy for ovarian dermoid cysts by laparoscopy or laparotomy. At discharge, patients were instructed to undergo a yearly ultrasound exam. A follow-up telephone call was conducted to assess whether an additional surgery for dermoid cysts was required and whether ultrasound recurrence of dermoid cysts was suspected.

Results: The study cohort included 102 participants (92 [90.2%] operated by laparoscopy and 10 [9.8%] by laparotomy). The mean follow-up from the index surgery to the interview was 72.1 ± 38.2 months. The rates of recurrent surgery were similar among women who underwent laparoscopic cystectomy compared with laparotomy (5/92 [5.4%] vs. 1/10 [10.0%], respectively; P = 0.5), while the rates of reported ultrasound recurrence were significantly lower in the laparoscopy group compared with the laparotomy group (10/102 [10.9%] vs. 4/10 [40.0%], respectively; P = 0.03). Additional factors including age, cyst diameter, diagnosis of torsion, intraoperative cyst spillage, estimated blood loss, intraperitoneal adhesions, and postoperative fever were not associated with recurrence.

Conclusions: Ultrasound recurrence of dermoid cysts is not uncommon and could be associated with the surgical approach.

Background: National registries for acromegaly and population-based data make an important contribution to disease understanding and management. Data concerning the epidemiology of acromegaly in Israel is scanty.

Objectives: To evaluate the epidemiology of acromegaly in different industrial areas in northern Israel.

Methods: Data from adult patients diagnosed with acromegaly from 2000 to 2020, living in Haifa and the western Galilee District were collected using the electronic database and medical records from Clalit Health Services. The prevalence of acromegaly in three distinct areas and overall were reported. In addition, other epidemiological data including associated co-morbidities, pituitary tumor size, and treatment modalities were collected.

Results: We identified 77 patients with a confirmed diagnosis of acromegaly. The overall prevalence was 155 cases/10⁶ inhabitants without statistically significant differences between the three areas. The mean age at diagnosis was 50 ± 1.8 years and the male to female ratio was 1.1. Macroadenoma and microadenoma were identified in 44 (57%) and 25 (33%), respectively. The frequency rate of acromegaly-associated co-morbidities such as diabetes, hypertension, carpal tunnel syndrome, and osteoporosis was similar to previously reported studies. The mean body mass index (BMI) was 29 ± 5.6 kg/m² .Obesity, with a BMI ≥ of 30 kg/m², was found in 29 patients (38%). The majority of patients underwent transsphenoidal surgery 67 (87%). Normalized insulin-like growth factor 1 was reported in 64 (83%).

Conclusions: A high prevalence of acromegaly was found in northern Israel. The pituitary microadenoma frequency rate is the highest reported.

Background: Low serum albumin is known to be associated with mortality in sepsis, as it reflects effects of nutrition, catabolism, and edema.

Objectives: To examine the association of albumin levels with in-hospital mortality in adults with sepsis, stratified by age groups.

Methods: This nationwide retrospective cohort study comprised patients admitted with sepsis to intensive care units in seven tertiary hospitals during 2003–2011. Only patients with available serum albumin levels at hospital admission and one week after were included. Patients with an intra-abdominal source of sepsis were excluded. The association between sepsis and mortality was analyzed using multivariate logistic regression models.

Results: The study included 3967 patients (58.7% male, median age 69 years). Mean serum albumin levels were 3.1 ± 0.7 g/dl at admission and 2.4 ± 0.6 g/dl one week later. In a multivariate logistic regression model, serum albumin one week after admission was inversely associated with in-hospital mortality (odds ratio [OR] 0.64, 95% confidence interval 0.55–0.73 per 1 g/dl). In an age-stratified analysis, the association was stronger with younger age (OR 0.44 for patients aged < 45 years, 0.60 for patients aged 45–65 years, and 0.67 for patients aged > 65 years). Serum albumin on admission was not associated with in-hospital mortality.

Conclusions: The decline in serum albumin one week after admission is a stronger predictor of mortality in younger patients. Older patients might have other reasons for low serum albumin, which reflect chronic co-morbidity rather than acuity of disease.

Background: Lower extremity amputation related to diabetes is a serious outcome, which can have devastating effects on the patient and family. The epidemiology of amputations has recently been used as a possible measure of the adequacy of medical prevention and treatment of diabetes and diabetic foot complications.

Objectives: To report on patients undergoing amputations at one medical center in Israel, their co-morbidities, and the outcomes.

Methods: A retrospective chart study was conducted of amputees operated between 1 September 2017 and 30 September 2018.

Results: The study population comprised 72 patients who had major amputations for diabetes and/or ischemia, mean age 72 ± 10 years, 74% males, 93% with type 2 diabetes. Mean age corrected Charlson Comorbidity Index was 8.2 ± 2.1 with 90% (65 patients) presenting with a score of 6 or higher. Before the recent deterioration, fewer than 20% of the patients exited their home routinely and 24% had an official diagnosis of dementia. There were 31 below knee amputations (BKA) and 41 above knee amputations (AKA). The 30-day, 3-month, 1-year, and 2-year mortality rates were 15.3%, 27.8%, 43.1%, and 54.2% respectively. Median survival period was 20 months. Survival after AKA was 13.4 ± 20, which was significantly less than after BKA (25.4 ± 2.7, P = 0.097).

Conclusions: Factors other than the quality of management of patients with diabetes and complications may contribute to amputation rates; thus, making speculations from international comparisons of raw amputation rates problematic. This population was less healthy than reported in most studies.
