Background: Recent guidelines have emphasized the importance of the diagnosis and treatment of obesity in all healthcare settings. However, obesity rarely appears as a chronic diagnosis during hospitalization, and there are few reports of targeted interventions.

Objective: To assess obesity-related diagnoses and interventions during pediatric acute hospitalization.

Methods: A retrospective cohort study was conducted in a pediatric ward. Hospitalization records of all patients aged 2–18 years were retrieved during a 30-month period. Weight percentile for patient age was calculated using the U.S. Centers for Disease Control and Prevention (CDC) age- and sex-adjusted charts. Patients with a weight-percentile-for-age of ≥ 95% were classified as suspected obesity. The characteristics of obesity-diagnosed patients were compared to obesity-overlooked patients.

Results: Of the hospitalized patients, 245/2827 (8.6%) had weight-percentile-for-age of ≥ 95%. Of these, 91/245 (37.4%) had obesity-related references in their medical record; 65/245 (26.5%) had a mean body mass index of 97.66% ± 2.6. Only 38/245 (15.5%) were diagnosed with obesity; weight-related recommendations only appeared in the discharge letter for 44/245 (17.9%). Multivariate analysis indicated that obesity was significantly more overlooked in preschoolers than in adolescents (adjusted odds ratio [OR] 11.78, 95% confidence interval [95%CI] 4.71–29.42), P < 0.001) and in patients, regardless of age, whose chief complaint was not abdominal (OR 7.7, 95%CI 1.92–30.8, P = 0.004).

Conclusions: Low rates of obesity-related diagnoses during pediatric acute hospitalization, especially in younger patients, are frequent. Pediatric staff should note obesity in patients and be trained in non-stigmatizing intervention during hospitalization.

Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommends a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) of less than 70% (FEV1/FVC < 0.7) after bronchodilators as the criteria for obstruction. However, because the FEV1/FVC ratio decreases with age, using a fixed ratio may lead to overdiagnosis of obstruction in the geriatric population. Using the lower limit of normal (LLN) as threshold for obstruction has been suggested.

Objectives: To determine the rate of overdiagnosis using the GOLD criteria compared to LLN in patients aged 60 and older. To find a better threshold with a minimal rate of over- and underdiagnosis.

Methods: The study population included adults aged 60 years and older who performed pulmonary function test (PFT) at Shaare Zedek Medical Center between 2014 and 2019 with results of FEV1/FVC < 0.7.

Results: We included 430 patients aged 60 years and older, 273 males (63.5%) and 157 females (36.5%). Mean age was 72 ± 8 years. Overdiagnosis was found in 35.6% of patients (95% confidence interval 31.1–40.3%) by using the GOLD criteria compared to the LLN. Overdiagnosis was reduced to 6.4% with the 0.65 threshold. The ideal point of the FEV1/FVC ratio where overdiagnosis and underdiagnosis were at their lowest rates was 0.638.

Conclusions: Use of the GOLD criteria for airflow obstruction may be associated with an overdiagnosis of more than 35% in patients older than 60 years. Lowering the FEV1/FVC ratio to < 0.65 might be more accurate in this population.

Nail psoriasis (NP) is a common manifestation of psoriasis, affecting up to 80–90% of patients with psoriatic arthritis and up to 60% of those with cutaneous psoriasis. Isolated NP also occurs in 5–10% of cases. It significantly impacts quality of life and may indicate or precede psoriatic arthritis. In this review, we summarized the clinical features of NP, highlighting patterns of matrix and nail bed involvement, and discussed differential diagnosis with onychomycosis. We outlined current topical, intralesional, systemic, and non-pharmacological treatment options, and proposed an evidence-based approach to diagnosis and management.

Psoriasis is a chronic immuno-inflammatory skin disorder characterized by rapid keratinocyte proliferation, forming thick, red patches with silvery scales. It affects 2–3% of the population, impacting skin, nails, and joints. Pathogenesis involves genetic, environmental, and immunological factors [1]. Triggers such as infections (especially Streptococcus), skin injuries, medications, stress, and alcohol can initiate or worsen the condition [1]. Psoriasis may follow a stable course or present in cycles of flare-ups and remissions. Skin involvement may manifest in any body area but is most common on the knees, elbows, trunk, and scalp [1]. Nail involvement appears in up to 60% of those with cutaneous psoriasis and 80% of those with psoriatic arthritis (PsA), with an 80–90% lifetime incidence [2,3]. Isolated nail psoriasis (NP), defined as nail changes without cutaneous psoriasis or with limited body surface involvement (< 5%), occurs in 5–10% of patients [4,5].

Background: Chest radiograph is a standard procedure for diagnosis of pneumonia; however, interpretation shows considerable variability among observers.

Objectives: To assess the extent of agreement between pediatric residents and board-certified radiologists in interpretation of chest radiography for detection of pneumonia. To evaluate the impact of resident experience, patient age, and signs of infection on this phenomenon.

Methods: The cohort included 935 patients with suspected pneumonia admitted to the pediatric emergency department at a non-tertiary medical center in Israel 2019–2021. All patients had chest radiographs interpreted by a resident and a radiologist. Interobserver agreement was assessed using Κ and prevalence-adjusted bias-adjusted κ (PABAK) with 95% confidence intervals (95%CI). Results were stratified by resident experience (junior or senior), patient age (≤ 3 vs. > 3 years), white blood cells (≤ 15,000 vs. > 15,000 cells/ml), C-reactive protein (≤ 5 vs. > 5.0 mg/dl), and temperature (< 38.0°C vs. ≥ 38.0°C).

Results: Moderate agreement between pediatric residents and radiologists was demonstrated for diagnosis of pneumonia (κ= 0.45). After adjustment for disease prevalence, the extent of agreement increased to near-substantial (PABAK= 0.59, 95% confidence interval 0.54–0.64). The extent of agreement was higher for children over 3 years of age and in patients without clinical or biochemical features of pneumonia, especially when diagnosis of pneumonia was ruled out.

Conclusions: A second reading of chest radiographs by an experienced radiologist should be considered, particularly for patients younger than 3 years of age and in those with signs of infection and an initial diagnosis of pneumonia.

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.

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: Laryngopharyngeal reflux (LPR) refers to the backflow of acidic stomach content into the larynx, pharynx, and upper aerodigestive tract. The diagnosis of LPR is based on the patient's history and findings of the laryngoscopy associated with LPR. Other possible manifestations consistent with LPR symptoms include laryngeal cancer, vocal fold granulomas, Reinke's space edema, and vocal polyps. In this study, we compared the characteristics of patients with LPR symptoms and incidental laryngeal findings (ILF) in the laryngoscopic evaluation to those without ILF (WILF).

Objectives: Determine the characteristics of LPR-symptomatic patients with ILF versus WILF.

Methods: In this retrospective study, we examined 160 medical charts from patients referred to the otolaryngology clinic at Galilee Medical Center for LPR evaluation 2016–2018. The reflux symptoms index (RSI), reflux finding score (RFS), and demographics of the patient were collected. All patients with a positive RSI score for LPR (RSI > 9) were included, and the profiles of patients with versus without ILF on laryngoscopy examination were compared.

Results: Of the 160 patients, 20 (12.5%) had ILF during laryngoscopy. Most had vocal cord findings such as leukoplakia (20%), polyps (15%), and nodules (20%). Hoarseness, throat clearing, swallowing difficulty, breathing difficulties, and total RSI score were significantly higher in patients with ILF.

Conclusions: Evaluation of LPR symptoms may provide otolaryngologists with a tool to identify patients with other findings on fiberoptic laryngoscopy. A laryngoscopic examination should be part of the examination of every patient with LPR to enable diagnosis of incidental findings.

Background: Computed tomography (CT) is the main diagnostic modality for detecting pancreatic adenocarcinoma.

Objectives: To assess the frequency of missed pancreatic adenocarcinoma on CT scans according to different CT protocols.

Methods: The medical records of consecutive pancreatic adenocarcinoma patients were retrospectively collected (12/2011–12/2015). Patients with abdominal CT scans performed up to a year prior to cancer diagnosis were included. Two radiologists registered the presence of radiological signs of missed cancers. The frequency of missed cancers was compared between portal and pancreatic/triphasic CT protocols.

Results: Overall, 180 CT scans of pancreatic adenocarcinoma patients performed prior to cancer diagnosis were retrieved; 126/180 (70.0%) were conducted using pancreatic/triphasic protocols and 54/180 (30.0%) used portal protocols. The overall frequency of missed cancers was 6/180 (3.3%) in our study population. The frequency of missed cancers was higher with the portal CT protocols compared to the pancreatic/triphasic protocols: 5/54 (9.3%) vs. 1/126 (0.8%), P = 0.01. CT signs of missed cancers included small hypodense lesions, peri-pancreatic fat stranding, and dilated pancreatic duct with a cut-off sign.

Conclusions: The frequency of missed pancreatic adenocarcinoma is higher on portal CT protocols. Physicians should consider the cancer miss rate on different CT protocols.

Common variable immunodeficiency (CVID) is a heterogeneous primary immune deficiency disorder characterized mainly by defective B lymphocyte differentiation, leading to hypogammaglobinemia and defective antibody production. It is often combined with cellular immune defects. A minority of patients present during childhood and adolescence. Infections are most often sinopulmonary but can affect any system. The noninfectious complications include progressive lung disease, autoimmunity, gastrointestinal inflammatory disease, liver disease, granulomatous disease, lymphoid hyperplasia and infiltrative disease, and the development of lymphoma and other cancers. In addition to recurrent infections and bronchiectasis, patients may develop chronic interstitial lung disease, granulomatous lung disease, lymphoma, and pulmonary hypertension.

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.

Recognizing myocarditis is a diagnostic and therapeutic challenge due to the heterogeneity of its clinical presentation and the wide range of etiologies. There is a lack of uniformity among position papers and guidelines from various professional societies regarding the definition and diagnostic workout, including recommendations for performing endomyocardial biopsy (EMB) and medical management, especially the use of immunosuppressive regimens [1-3]. Moreover, there is significant variability among medical centers in Israel in the diagnostic and therapeutic approaches to acute myocarditis. The purpose of this position paper is to present ways to standardize the management of acute myocarditis in Israel [4] by providing up-to-date definitions of the clinical categories of myocarditis, diagnostic criteria, and therapeutic approaches that correspond to the realities of our healthcare system.

Background: Jejunal disease is associated with worse prognosis in Crohn's disease. The added value of diffusion weighted imaging for evaluating jejunal inflammation related to Crohn's Disease is scarce.

Objectives: To compare diffusion weighted imaging, video capsule endoscopy, and inflammatory biomarkers in the assessment of Crohn's disease involving the jejunum.

Methods: Crohn's disease patients in clinical remission were prospectively recruited and underwent magnetic resonance (MR)-enterography and video capsule endoscopy. C-reactive protein and fecal-calprotectin levels were obtained. MR-enterography images were evaluated for restricted diffusion, and apparent diffusion coefficient values were measured. The video capsule endoscopy-based Lewis score was calculated. Associations between diffusion weighted imaging, apparent diffusion coefficient, Lewis score, and inflammatory biomarkers were evaluated.

Results: The study included 51 patients, and 27/51 (52.9%) with video capsule endoscopies showed jejunal mucosal inflammation. Sensitivity and specificity of restricted diffusion for video capsule endoscopy mucosal inflammation were 59.3% and 37.5% for the first reader, and 66.7% and 37.5% for the second reader, respectively. Diffusion weighted imaging was not statistically associated with jejunal video capsule endoscopy inflammation (P = 0.813).

Conclusions: Diffusion weighted imaging was not an effective test for evaluation of jejunal inflammation as seen by video capsule endoscopy in patients with quiescent Crohn's disease.

Children affected with Poland syndrome are born with missing or underdeveloped muscles (typically pectoralis major) on one side of the body. Breast abnormalities such as unilateral hypoplasia or agenesis of the breast and nipple may also occur. Other muscles on the affected side, including other muscles in the chest wall, shoulder, arm, and hand, may be missing or underdeveloped [1]. Ribs may be noticeable due to the loss of subcutaneous fat. Sparse or absent axillary and pectoral hairs are a common manifestation of this syndrome.

Fetal hydrops is a life-threatening condition defined as abnormal accumulation of fluid in two or more fetal compartments: ascites, pleural effusion, pericardial effusion, or generalized skin edema [1]. Fetal hydrops may also be associated with polyhydramnios and placental edema [2].

Based on pathophysiology results, fetal hydrops is classified as either immune or non-immune. The frequency of immune fetal hydrops has decreased dramatically since the development of Rh (D) immunization given to mothers at risk. Nonimmune hydrops fetalis (NIHF) accounts for almost 90% of cases [1]. The etiology of NIHF is further classified as cardiovascular (17–35%), chromosomal (7–16%), hematologic (4–12%), infectious (5–7%), and unknown (15–25%). Inborn errors of metabolism account for only 1–2% of NIHF cases [1]. NIHF is commonly progressive. Complete resolution of NIHF before birth is rare.

Global developmental delay (GDD), defined as a significant delay in two or more developmental domains (e.g., gross/fine motor, cognitive, speech/language, personal/social, activities of daily living), affects 1–3% of children. According to the Israeli Ministry of Health, thyroid function studies are not indicated in children with GDD unless there are systemic features suggestive of thyroid dysfunction (https://www.health.gov.il/hozer/mr36_2012.pdf). This approach also exists in other countries with newborn screening programs for congenital hypothyroidism.

We present the case of an infant with GDD, who despite normal newborn screening tests, underwent a repeated extended thyroid function analysis (including T₃ levels) leading to a diagnosis of Allan-Herndon-Dudley syndrome, a rare genetic neurodevelopmental syndrome.
