Background: Serum ferritin is a sensitive inflammatory biomarker reflecting cell damage and oxidative stress in inflammatory rheumatic diseases. The use of ferritin for assessment of systemic sclerosis (SSc) activity, severity, and prognosis has not been fully elucidated.

Objectives: To assess the correlation between serum ferritin levels and SSc disease parameters, complications, and outcome.

Methods: Demographic, clinical, and laboratory data, including blood levels of ferritin, were collected from files of patients with SSc who were treated at the Rheumatology Institute at Rambam Health Care Campus from January 2004 to July 2021. The study compared SSc patients with elevated levels of ferritin to those with normal levels.

Results: We extracted data of 241 SSc patients (80% female, 60% with diffuse SSc, mean age 54 ± 15.4 years, mean disease duration 6.8 ± 4.5 years). During follow-up, 39% died. Elevated ferritin levels positively correlated with male sex; short disease duration; lung, heart, and kidney involvement; higher modified Rodnan skin score; anemia; elevated levels of creatinine kinase, C-reactive protein, creatinine, and troponin; reduced pulmonary function tests (forced vital capacity and diffusion capacity of the lung for carbon monoxide); and left ventricular ejection fraction. There were no correlations between ferritin levels and pulmonary hypertension or gastrointestinal involvement. Levels of ferritin negatively correlated with anti-centromere antibodies.

Conclusions: In SSc, ferritin can serve as a marker for ongoing systemic inflammation and prognosis, particularly in patients with lung and heart involvement. Further studies on serial ferritin measurement in the management of SSc patients are warranted.

Background: Pelvic organ prolapse in pregnancy is rare. Consequent complications include cervical infection, spontaneous abortion, and premature birth. Conservative management by means of a pessary have been described as improving maternal symptomatology and minimizing gestational risk. The delivery mode is controversial.

Objective: To describe the clinical courses of patients diagnosed with pelvic organ prolapse during pregnancy, and to present our multidisciplinary approach.

Methods: In this retrospective case series, we summarized the obstetrical outcomes of women diagnosed with pelvic organ prolapse during pregnancy in a single university-affiliated hospital.

Results: We identified eight women with advanced uterine prolapse at a mean age of 30.3 years. Seven were diagnosed with advanced uterine prolapse (Pelvic Organ Prolapse Quantification [POPQ] stage ≥ 3). All were treated by pessary placement, which was tolerable and provided symptomatic relief. The pessary type was chosen according to the prolapse stage. In women with cervical prolapse POPQ stage > 2 and cervical edema, a support pessary was less beneficial. However, the prolapse was well-controlled with a space-filling Gellhorn pessary. Low complication rates were associated with vaginal deliveries. The few complications that were reported included minor cervical laceration, postpartum hemorrhage, and retained placenta.

Conclusions: Treatment of pelvic organ prolapse during pregnancy must be individualized and requires a multidisciplinary approach of urogynecologists, obstetricians, dietitians, pelvic floor physiotherapists, and social workers. Conservative management, consisting of insertion of a vaginal pessary when prolapse symptoms appeared, provided adequate support for the pelvic floor, improved symptomatology, and minimized pregnancy complications. Vaginal delivery was feasible for most of the women.

The prevalence of difficult-to-treat rheumatoid arthritis (D2T RA) varies between 5% and 25%, with females comprising the majority of patients and no difference in patient age between D2T and non-D2T RA cohorts. While several attempts to subclassify D2T RA patients into defined subgroups have been tried, the inclusion of an individual D2T RA patient to one of the predefined subgroups can be difficult or impossible as multiple factors are usually involved in the mechanisms of rheumatoid arthritis (RA) refractoriness, with the complex interplay of inflammatory, structural, social, and psychological factors being unique for each patient. More severe disease at presentation, including seropositivity and early erosion formation, and insufficiently aggressive initial treatment can both contribute to the eventual development of D2T RA. No single test or study can replace the holistic clinical approach to the diagnosis and understanding of the causation of D2T RA. Traditional in-depth clinical history and thorough clinical examination remain sine qua non in managing D2T RA patients. Multifaceted contributions of inflammatory and non-inflammatory components create the uniqueness of D2T RA and dictate a comprehensive approach to the management, including both pharmacologic and non-pharmacological therapeutic strategies. Mean annual total costs for D2T RA patients have been estimated as being about twice as high as that of patients with non-D2T RA.

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.

Idiopathic eosinophilic vasculitis is a newly recognized form of hypereosinophilic syndrome. While little is understood about the condition, criteria for its definition have been proposed. We aimed to determine whether three patients with eosinophilia and vasculitis could be retrospectively diagnosed with this condition. We performed a retrospective descriptive analysis on three cases with hypereosinophilia and vasculitis who were treated in Sheba Medical Center, Sourasky Medical Center, and Meir Medical Center in Israel between 2009 and 2021. A thorough review of all three cases was conducted. The findings were compared to the suggested criteria for idiopathic eosinophilic vasculitis.

All patients shared the symptoms of progressive limb ischemia, eosinophilic rash, and peripheral neuropathy that are consistent with vasculitis. No lower or upper respiratory abnormalities or the presence of anti-neutrophil cytoplasmic antibodies (ANCA) autoantibodies associated with eosinophilic granulomatosis with polyangiitis were detected. Primary monoclonal abnormalities, drug interactions, infections, allergy, and other secondary causes of hypereosinophilia were excluded. After a thorough review, we suggest that our three patients with previously unexplained hypereosinophilia and vasculitis fit the diagnosis of idiopathic eosinophilic vasculitis. These results highlight the existence of this novel condition and the importance of its recognition and consideration as part of the differential diagnosis in patients with marked eosinophilia and vasculitis. Further research for elucidating the mechanisms and treatment approach for this potentially severe condition is urgently needed.

A 90-year-old female with a medical history of untreated gout presented to the emergency department with acute low back pain. On physical examination, the area over the 4th lumbar spinous process was extremely tender. Serum C-reactive protein was 184 mg/L, and uric acid was 8.3 mg/dl.

Conventional [Figure 1A] and dual-energy computed tomography (DECT) [Figure 1B] studies of the lumbar spine showed multiple tophi-engulfing posterior vertebral structures of the involved vertebral unit, including the spinous and transverse processes and facet joints. This condition is schematically shown in Figure 1C with asterixis indicating tophi-induced erosion and osteolysis of the spinous process.

The patient was treated for a suspected acute gouty attack with prednisone and colchicine followed by allopurinol treatment with rapid and uneventful recovery.

Axial gout is an underdiagnosed and potentially curable cause of recurrent low back pain [1,2]. Referral to DECT should be considered in patients with uncontrolled gout and concurrent back pain.

We read with interest the retrospective study by Ohana Sarna and colleagues [1] titled Clinical Characteristics, Etiology, and Outcomes of Hypothermia in Well-appearing Children Referred to the Emergency Department. The study comprised 99 children younger than 16 years of age who presented to pediatric emergency department (PED) with hypothermia (temperature of < 36.5°C). The authors evaluated the incidence of serious bacterial infection (SBI) in 15 infants aged 0–3 months, 71 children aged 3–36 months, and 13 children older than 36 months. They concluded that the incidence of SBI in infants younger than 3 months of age was low and the older children had a benign course and outcome. As pediatric endocrinologists, we would like to mention another important cause of hypothermia, especially in infants but also in children: congenital and acquired hypothyroidism.

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.

Inflammatory myopathies include polymyositis, necrotizing autoimmune myositis, dermatomyositis, juvenile inflammatory myopathy, and inclusion body myositis. These diseases are classified based on the different clinical and pathological characteristics unique to each of them [1]. Dermatomyositis is a rare disease with an incidence of 6–10 cases/1,000,000 a year with the highest incidence in the 7th decade of life as reported by a Norwegian cohort in a Caucasian population [2].

Diagnosis of dermatomyositis is based on typical signs and symptoms combined with laboratory results, imaging, and electromyography findings and muscle biopsy. Historically, the diagnosis of dermatomyositis was based on the classification criteria named after Bohan and Peter published in 1975. Many other classification criteria were proposed subsequently, the latter by the European League Against Rheumatism/American College of Rheumatology (EULAR/ACR), which were published in 2020 [3].

The clinical features of dermatomyositis are diverse. Skin manifestations can accompany or precede muscle weakness. Classical skin findings include periorbital heliotrope rash and a rash of the upper chest, back, and shoulders, known as the V sign and shawl sign respectively, as well as the Gottron's papules on the knuckles. Another skin appearance is subcutaneous calcifications that break periodically through the skin causing ulcerations. Dermatomyositis usually manifests as a symmetrical proximal muscle weakness but can present with preserved strength called amyopathic dermatomyositis [1].

Background: The cavum septi pellucidi (CSP) is a brain-enclosed cavity located on the midline between the two leaflets of the septum pellucidum that separates the lateral ventricles. This structure develops in the fetus from week 18 and can be seen up to week 37 in almost all cases and then begins to disappear.

Objectives: To measure and determine the normative values of the CSP volume in fetuses between 20 to 40 weeks of gestation.

Methods: The study comprised 161 consecutive pregnant women between 20 to 40 weeks of gestation with single viable fetuses. All patients had normal, disease-free pregnancies. Transvaginal or transabdominal ultrasound was used according to the fetal presentation. The fetal head was assessed in mid-sagittal sections. Once the CSP was visualized, its volume was measured using three-dimensional ultrasound with Virtual Organ Computer-aided Analysis software. The width of the CSP was also measured at the biparietal diameter (BPD) plane.

Results: Of the 161 fetuses, the CSP volume was measured in 158. In three patients the CSP was not identified. The CSP volume correlated poorly with gestational age (r=0.229) and with the BPD (r=0.295). The mean CSP volume was 0.508 ± 0.372 ml (range: 0.03-1.78 ml). The simple measurement of the CSP width correlated better with gestational age (r=0.535) and the BPD (r=0.484).

Conclusions: The CSP volume had a poor correlation with gestational age; however, the volume did not exceed 2 ml regardless of gestational age. This information can be used to assess pathologies involving the CSP.

 

Background: Survivors of critical illness are at increased risk of long-term impairments, referred to as post-intensive care unit (ICU) syndrome (PICS). Post-traumatic stress disorder (PTSD) is common among ICU survivors with reported rates of up to 27%. The prevalence of PTSD among Israeli ICU survivors has not been reported to date.

Objectives: To evaluate the prevalence of new onset PTSD diagnosed in a post-ICU clinic at a tertiary center in Israel.

Methods: We conducted a retrospective, single center, cohort study. Data were collected from medical records of all patients who visited the Tel Aviv Sourasky Medical Center post-ICU clinic between October 2017 and June 2020. New onset PTSD was defined as PTSD diagnosed by a certified board psychiatrist during the post-ICU clinic visit. Data were analyzed using descriptive statistics.

Results: Overall, 39 patients (mean age 51 ± 17 years, 15/39 females [38%]) attended the post-ICU clinic during the study period. They were evaluated 82 ± 57 days after hospital discharge. After excluding 7 patients due to missing proper psychiatric analysis, 32 patients remained eligible for the primary analysis. New PTSD was diagnosed in one patient (3%).

Conclusions: We found lower incidence of PTSD in our cohort when compared to existing literature. Possible explanations include different diagnostic tools and low risk factors rate. Unique national, cultural, and/or religious perspectives might have contributed to the observed low PTSD rate. Further research in larger study populations is required to establish the prevalence of PTSD among Israeli ICU survivors.

Artificial intelligence (AI) has emerged as a powerful technology in medicine, with a potential to revolutionize various aspects of disease management. In recent years, substantial progress has been made in the development and implementation of AI algorithms and models for the diagnosis, screening, and monitoring of retinal diseases. We present a brief update on recent advancements in the implementation of AI in the field of retinal medicine, with a focus on age-related macular degeneration, diabetic retinopathy, and retinopathy of prematurity. AI algorithms have demonstrated remarkable capabilities in automating image analysis tasks, thus enabling accurate segmentation and classification of retinal pathologies. AI-based screening programs hold great promise in cost-effective identification of individuals at risk, thereby facilitating early intervention and prevention. Future integration of multimodal imaging data including optical coherence tomography with additional clinical parameters, will further enhance the diagnostic accuracy and support the development of personalized medicine, thus aiding in treatment selection and optimizing therapeutic outcomes. Further research and collaboration will drive the transformation of AI into an indispensable tool for improving patient outcomes and enhancing the field of retinal medicine.

Background: Pregnant women are at higher risk for severe coronavirus disease 2019 (COVID-19). Since the release of the BNT162b2 messenger RNA vaccine (Pfizer/BioNTech), there has been accumulated data about the three vaccine doses. However, information regarding obstetric and neonatal outcomes of pregnant women vaccinated with the third (booster) vaccine is limited and primarily retrospective.

Objectives: To evaluate the obstetric and early neonatal outcomes of pregnant women vaccinated during pregnancy with the COVID-19 booster vaccine compared to pregnant women vaccinated only by the first two doses.

Methods: We conducted a cross-sectional study of pregnant women who received the BNT162b2 vaccine during pregnancy. Obstetric and neonatal outcomes were compared between pregnant women who received only the first two doses of the vaccine to those who also received the booster dose.

Results: Overall, 139 pregnant women were vaccinated during pregnancy with the first two doses of the vaccine and 84 with the third dose. The third dose group received the vaccine earlier during their pregnancy compared to the two doses group (21² vs. 31⁵ weeks, respectively, P < 0.001). No differences in obstetric and early neonatal outcomes between the groups were found except for lower rates of urgent cesarean delivery in the third dose group (adjusted odds ratio 0.21; 95% confidence interval 0.048–0.926, P = 0.039).

Conclusions: Compared to the first two doses of the BNT162b2 vaccine given in pregnancy, the booster vaccination is safe and not associated with an increased rate of adverse obstetric and early neonatal outcomes.

A 52-year-old man with a history of gout presented to the emergency department with painful purulent ulcers on the left index finger. Serum C-reactive protein was elevated to 112 mg/L. Hand radiographs [Figure 1A] demonstrated almost complete osteolysis of the two distal phalanges of the involved finger (asterisk), with multiple typical gouty erosions with sclerotic margins and overhanging edges in a marginal and juxta-articular distribution (white arrows), and soft tissue tophi (black arrows). Osteomyelitis of the index finger was suspected, and the finger was amputated.

Idiopathic inflammatory myopathies (IIM) are a group of rare, autoimmune, systemic diseases with a large spectrum of clinical phenotypes. The diagnosis and management of myositis demand an integrated evaluation of different clinical, laboratory, and pathological findings in various organs. Recent developments in IIM research, especially in the serological testing and pathology fields, has led to a new classification and better recognition of patients with early or extra-muscular disease, with improvement in clinical care and prognosis.
