Background: Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a rare autoimmune demyelinating disorder of the central nervous system. Optic neuritis (ON) is the most common clinical manifestation of MOGAD in adults. In 2023, new MOGAD diagnostic criteria were proposed, highlighting the importance of supplemental criteria when MOG-immunoglobulin G (IgG) titers are unavailable.

Objective: To investigate the applicability of the 2023 MOGAD criteria in patients diagnosed with MOGAD and treated before the availability of MOG-IgG titers.

Methods: We conducted a retrospective chart review of patients classified as MOGAD between 2010 and 2023 at Rabin Medical Center. Patient demographics as well as clinical and imaging data were collected, including visual acuity, expanded disability status score, core demyelinating events, antibody status, and brain and optic nerve magnetic resonance imaging data. Patients fulfilling the 2023 MOGAD criteria were reported as definite MOGAD.

Results: Fifteen patients met the 2023 MOGAD diagnostic criteria despite lack of MOG-IgG titer. The most common supplemental criterion meeting the 2023 MOGAD criteria was optic disc edema (n=12, 80%), followed by longitudinal optic nerve involvement (53%), bilateral ON (40%), and perineural optic sheath enhancement (33%).

Conclusions: All patients with a clinical diagnosis of MOG-ON in our cohort fulfilled the 2023 MOGAD criteria despite the lack of antibody titers. The 2023 MOGAD criteria can be reliably applied to Israeli cohorts, prior to availability of MOGAD IgG titers, with particular attention to additional supplemental criteria. Since the 2023 MOGAD criteria were published, MOGAD IgG titers have been added to routine testing at our facility.

Since the introduction of the international study group (ISG) criteria for the diagnosis of Behçet's disease (BD) in the early 1990s by Yazici and colleagues [1] and the international criteria for BD (ICBD) by Davatchi and colleagues in 2014 [2], great progress has been achieved in the diagnosis of BD with fairly high sensitivity and specificity rates. However, a small, but very challenging and unique minority might not fulfill these criteria, at least at presentation. These patients are most challenging as they may present with life-threatening vascular or neurological manifestations. If the diagnosis BD is delayed, the risk for morbidity and even mortality might be increased. Therefore, we should aim for early diagnosis and prompt treatment.

Background: Syncope is a common reason for emergency department (ED) visits; however, the decision to admit or discharge patients after a syncopal episode remains challenging for emergency physicians. Decision rules such as the Boston Syncope Criteria have been developed in an attempt to aid clinicians in identifying high-risk patients as well as those who can be safely discharged, but applying these rules to different populations remains unclear.

Objectives: To determine whether the Boston Syncope Criteria are valid for emergency department patients in Israel.

Methods: This retrospective cohort convenience sample included patients who visited a tertiary care hospital in Jerusalem from August 2018 to July 2019 with a primary diagnosis of syncope. Thirty-day follow-up was performed using a national health system database. The Boston Syncope Criteria were retrospectively applied to each patient to determine whether they were at high risk for an adverse outcome or critical intervention, versus low risk and could be discharged.

Results: A total of 198 patients fulfilled the inclusion criteria and completed follow-up. Of these, 21 patients had either an adverse outcome or critical intervention. The rule detected 20/21 with a sensitivity of 95%, a specificity of 66%, and a negative predictive value of 99%.

Conclusions: The Boston Syncope Criteria may be useful for physicians in other locations throughout the world to discharge low-risk syncope patients as well as identify those at risk of complications

Background: The lack of organs for liver transplantation has prompted transplant professionals to study potential solutions, such as the use of livers from donors older than 70 years. This strategy is not widely accepted because potential risks of vascular and biliary complications and recurrence of hepatitis C.

Objectives: To examine the efficacy and safety of liver grafts from older donors for transplantation.

Methods: A retrospective analysis of data on 310 adults who underwent deceased donor liver transplantation between 2005 and 2015 was conducted. We compared graft and recipient survival, as well as major complications, of transplants performed with grafts from donors younger than 70 years (n=265, control group) and those older than 70 years (n=45, older-donor group), followed by multivariate analysis, to identify risk factors.

Results: There was no significant difference between the control and older-donor group at 1, 5, and 10 years of recipient survival (79.5% vs. 73.3%, 68.3% vs. 73.3%, 59.2% vs. 66.7%, respectively) or graft survival (74.0% vs. 71.0%, 62.7% vs. 71.0%, 54.8% vs. 64.5%, respectively). The rate of biliary and vascular complications was similar in both groups. Significant risk factors for graft failure were hepatitis C (hazard ratio [HR] = 1.92, 95% confidence interval [95%CI] 1.16–2.63), older donor age (HR = 1.02, 95%CI 1.007–1.031), and male gender of the recipient (HR = 1.65, 95%CI 1.06–2.55).

Conclusion: Donor age affects liver graft survival. However, grafts from donors older than 70 years may be equally safe if cold ischemia is maintained for less than 8 hours.

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative. These patients are recognized as seronegative Obs-APS.

We reviewed evidence of non-criteria Obs-APS and discuss a case of a woman with a diagnosis of active systemic lupus erythematosus (SLE) and non-criteria Obs-APS with four consecutive pregnancy losses. After an accurate diagnosis the patient received prenatal counseling and benefited from the optimal treatment of Obs-APS that led to a successful pregnancy. The applicability of this successful experience about outcomes in women with non-criteria, or seronegative, Obs-APS is also evaluated.

 

In recent years, salivary gland ultrasonography (SGUS) has emerged as a promising tool for the diagnosis and prognostic stratification of patients with primary and secondary Sjögren’s syndrome. Several studies have emphasized that salivary ultrasonography could be a highly specific tool for the diagnosis of the disease. However, before it can be used in daily clinical practice the SGUS procedure needs standardization and validation in larger disease-control groups. In this review we provide an update on the role of SGUS in the diagnostic algorithm of primary Sjögren’s syndrome.

Background: A new approach for assessing non-cognitive attributes in medical school candidates was developed and implemented at the Hebrew University Medical School. The non-cognitive tests included a biographical questionnaire, a questionnaire raising theoretical dilemmas and multiple mini-interviews.

Objectives: To evaluate the effects of the change in the admission process on students' demographics and future career choices.

Methods: A questionnaire including questions on students’ background and future residency preferences was administered to first-year students accepted to medical school by the new admission system. Results were compared with previous information collected from students admitted through the old admission process.

Results: Students accepted by the new process were significantly older (22.49 vs. 21.54, P < 0.001), and more had attended other academic studies before medical school, considered other professions besides medicine, and majored in humanities combined with sciences in high school. Significantly more students from small communities were admitted by the new system.  Differences were found in preferences for future residencies; compared with the old admission process (N=41), students admitted by the new system (N=85) had a more positive attitude towards a career in obstetrics/gynecology (41% vs. 22%, P < 0.001) and hematology/oncology (11.7% vs. 4.8%, P < 0.001), while the popularity of surgery and pediatrics had decreased (34.5% vs. 61%, P < 0.001 and 68.7% vs. 82.5%, P < 0.001 respectively).

Conclusions: Assessment of non-cognitive parameters as part of the admission criteria to medical school was associated with an older and more heterogenic group of students and different preferences for future residency. Whether these preferences in first-year students persist through medical school is a question for further research.
 

Background: The criteria for tonsillectomy for recurrent tonsillitis were established by prospective studies in the pediatric population and are applied to adults as well. No studies have been conducted to assess whether these guidelines are followed. 

Objectives: To examine the eligibility for tonsillectomy of tonsillectomized patients who were referred because of recurrent acute tonsillitis.

Methods: A retrospective case series in an ambulatory military otolaryngology clinic was conducted, and the medical records of 44 tonsillectomized patients who suffered from throat infections in the year before surgery were analyzed. The number of tonsillar infections that met the referral criteria was counted.

Results: The average number of throat infections that met the referral criteria was 1.89 per year. The average number of visits to the clinic due to upper respiratory tract infection was 12.92 (range 2–36) per year. The average number of visits for any cause was 45.13 (range 6–64) per year. One patient with eight documented throat infections met the criteria of more than six infections in the last year.

Conclusion: Although the referral criteria were not strictly met, we speculate that surgery was probably beneficial. This study shows that the indications for tonsillectomy referral are not strictly followed, and that new criteria for referral of adults for tonsillectomy need to be established.

Background: Hip fracture rates are increasing worldwide, and the risk for a second hip fracture is high. The decision to administer antiresorptive treatment is based mainly on bone mineral density and/or a history of previous osteoporotic fractures.

Objectives: To evaluate the contribution of BMD[1], previous fractures, clinical and laboratory parameters to hip fracture risk assessment.

Methods: The study population included 113 consecutive hip fracture patients, aged 72.5 ± 9.4 years, discharged from the Department of Orthopedic Surgery113 consecutive patients, 87 women and 26 men, aged 50-90 years, mean ag. BMD was assessed at the lumbar spine, femoral neck and total hip. The results were expressed in standard deviation scores as T-scores – compared to young adults and Z-scores – compared to age-matched controls. Plasma or serum levels of parathyroid hormone, 25-hydroxyvitamin 3 and urinary deoxypyridinoline cross-links were evaluated.

Results: We observed T-scores ≤-2.5 in 43 patients (45.3%) at the lumbar spine, in 47 (52.2%) at the femoral neck and in 33 (38%) at the total hip. Twenty-eight patients (29.5%) had neither low BMD nor previous osteoporotic fractures. Using a T-score cutoff point of (-1.5) at any measurement site would put 25 (89%) of these patients into the high fracture risk group. Mean DPD level was 15.9 ± 5.8 ng/mg (normal 4–7.3 ng/mg creatinine). Vitamin D inadequacy was observed in 99% of patients.

Conclusions: Using current criteria, about one-third of elderly hip fracture patients might not have been diagnosed as being at risk. Lowering the BMD cutoff point for patients with additional risk factors may improve risk prediction yield.
