Immune thrombocytopenia (ITP), driven by autoantibodies targeting platelet antigens, is an acquired disorder posing considerable challenges, particularly in pregnancy, where its prevalence escalates to 1–3 per 10,000 women, a tenfold increase compared to the general population [1]. Predominantly characterized by a heightened risk of bleeding, particularly during pregnancy, the incidence of significant hemorrhagic events stands at approximately 18%, mostly non-severe [1]. Despite its rarity, thrombosis can manifest as a complication, especially when accompanied by antiphospholipid antibodies, which amplify the propensity for arterial and venous thrombotic events alongside obstetric complications and thrombocytopenia [2,3].

In this case report, we present the case of a young female with primary unexplained infertility, complicated by ITP and antiphospholipid syndrome (APS), predisposing her to increased bleeding and thrombotic risks. During a multidisciplinary consultation, the medical staff navigated the intricate landscape of fertility treatments and pregnancy options, carefully considering the delicate balance between risks and benefits to optimize patient outcomes.

Background: Inflammatory and thrombotic markers play crucial roles in risk stratification for various diseases.

Objectives: To investigate the relative importance of inflammation, measured by C-reactive protein (CRP), and platelet turnover, indicated by immature platelet fraction (IPF), in predicting outcomes for patients with cardiovascular disease, coronavirus disease 2019 (COVID-19), and bacterial infections.

Methods: In this retrospective observational study, we analyzed data from 1473 individuals admitted to the Samson Assuta Ashdod University Hospital between 2018 and 2022. Patients were categorized based on CRP and IPF levels, with a focus on 280 patients in the high CRP/low IPF or high IPF/low CRP tertiles.

Results: The high CRP low IPF group demonstrated significantly higher mortality rates compared to the low CRP high IPF group (13.5% vs. 0.8%, P < 0.001). Logistic regression analysis revealed that the high CRP and low IPF combination was the strongest predictor of mortality (odds ratio 12.951, 95% confidence interval 1.409–119.020, P = 0.024).

Conclusions: The combination of inflammatory (CRP) and thrombotic (IPF) markers provides superior prognostic information compared to individual disease diagnoses in patients with cardiovascular disease, COVID-19, and bacterial infections.

Background: Allergic contact dermatitis (ACD), a prevalent skin disorder marked by delayed hypersensitivity reactions to specific allergens, is commonly diagnosed through patch testing. Previous studies have indicated lower rates of positive patch tests in summer months compared to winter months.

Objectives: To investigate whether there is a difference in the proportion of positive patch test results between summer and winter months.

Methods: A retrospective study was performed on 1128 patients, with 14 individuals undergoing two tests each, resulting in a total of 1142 patch tests. The tests were conducted at a major tertiary referral center between 2016 and 2020. The data set encompassed patient demographics and comprehensive patch test results.

Results: Of the 1142 tests conducted, 808 (70.8%) yielded a positive response. The most frequently administered test series was the European standard series, conducted for 1135 (99.3%) of the tests, with 559/1135 (49.2%) showing positive results, followed by the cosmetics series (394/1120, 35.1%) and fragrances series (61/118, 51.7%). No statistically significant difference was observed in the proportion of positive patch tests between summer and winter months (313/419, 74.7% vs. 175/245, 71.4%, respectively; P-value = 0.35). There was no statistically significant difference in the rate of testing each specific series between the summer and winter months, except for the fragrances series.

Conclusions: We found no significant difference in the positive patch test rates between the summer and winter months. Therefore, patch testing can be reliably conducted during the summer without an increased risk of false-negative results.

Anifrolumab is a monoclonal antibody approved by the U.S. Food and Drug Administration in 2021 for the treatment of moderate-to-severe systemic lupus erythematosus (SLE) (excluding renal or neurological involvement). The drug inhibits the type 1 interferon receptor. Its safety and efficacy were evaluated through three placebo-controlled studies [1]. Clinical studies have demonstrated the beneficial effects of anifrolumab as an adjunct to standard therapy for SLE with cutaneous manifestations. Common side effects include upper respiratory tract infections, infusion-related reactions, herpes zoster, and hypersensitivity phenomena. Importantly, no serious skin reactions have been previously associated with the use of anifrolumab [2].

To the best of our knowledge, this is the first reported case of drug-induced bullous pemphigoid (DIBP) following treatment with anifrolumab.

Infantile hemangioma (IH) is the most common benign vascular tumor in infancy. Recent advances, particularly in beta-blocker therapy, have significantly improved the management of IHs. Early identification and treatment of IH may help reduce morbidity and associated complications. In this review, experts in pediatric dermatology in Israel who have experience in treating IH formulated national guidelines for the diagnosis and treatment of IHs, providing evidence-based recommendations for selecting appropriate therapeutic approaches. These Israeli national guidelines provide a structured approach to the diagnosis and treatment of IH, emphasizing early referral, appropriate treatment selection, and careful monitoring. The guidelines serve as a critical resource for pediatricians and dermatologists, ensuring optimal patient outcomes while minimizing complications.

Background: High prevalence of hepatitis C (HCV) among people with severe mental illness (SMI) is attributed mostly to current or past intravenous (IV) drug use. However, such history may disappear from patient files over time, especially in chronic SMI with prolonged psychiatric admissions.

Objectives: To explore HCV and SMI cross-morbidity (HCV/SMI) in a hospitalized population.

Methods: In this observational, retrospective, historical computerized study we examined prevalence, characteristics, and outcomes of patients with HCV/SMI compared to HCV alone in patients admitted to an Israeli hospital 1 January 2005 to 31 December 2020.

Results: Of 1638 eligible HCV patients, 219 (13.4%) were HCV/SMI. Significantly more native Israelis showed HCV/SMI than HCV alone (36.1% vs. 18.1%, P = 0.013) and history of IV drug use (60.3% vs. 32.4%, P < 0.001). Among Israeli natives, more Jews were SMI/HCV compared to HCV only (67.1% vs. 45%, P < 0.01). Among non-native Israelis, immigration age was lower in SMI/HCV compared to HCV only (27.97 vs. 37.23 years, P < 0.001). No differences were found in mortality or cirrhosis, although HCV/SMI patients experienced earlier mortality compared to HCV alone (61.42 ± 14.3 vs. 72.8 ± 14.6 years, P < 0.001). Cirrhosis among HCV/SMI patients was a risk factor for early mortality (hazard ratio 5.528, 95% confidence interval 3.721–8.213).

Conclusions: HCV/SMI is related to early mortality, particularly with cirrhosis. There is significantly high SMI prevalence in hospitalized HCV patients, representing a unique at-risk population. Identification during hospitalization and medical recommendations at discharge may fill the gaps.

Background: Uninterrupted antithrombotic treatment (ATT) during cardiac implantable electronic device (CIED) implantation increases bleeding and device-related infections (DRI) risk. The wide-awake-local-anesthesia-no-tourniquet (WALANT) technique, using large-volume local anesthesia and adrenaline, is successful in hand surgeries but its potential to mitigate bleeding risk in CIED implantations remains unknown.

Objectives: To investigate whether WALANT protocol for CIED implantations reduces clinically significant pocket hematoma in patients with a high bleeding risk or is a contraindication for interrupting ATT.

Methods: We conducted a prospective, double-blind, randomized controlled trial with CIED surgery patients on uninterrupted ATT. They received WALANT protocol (lidocaine 1% with adrenaline 1:100,000) or standard protocol (lidocaine 1%). Following implantation, patients were blindly monitored in the ward and pacemaker clinic. Patients were monitored for bleeding outcomes post-implantation.

Results: Forty-six consecutive patients (73.6 ± 9 years, 72% male) were enrolled. In the WALANT group (n=24) no intra-pocket pro-hemostatic agents were needed, compared to 45% in the control group (P = 0.0002). Postoperative pressure dressings were used in 12.5% vs. 68% (P = 0.0002). WALANT patients had smaller hematoma areas (median 3.7 cm² IQR [1–39] vs. 46 cm² [IQR 24–76], P = 0.0004) 1-day postoperative. ATT interruption occurred in 12.5% vs. 18% (P = 0.7). Superficial skin infection rates were 4% vs. 9% (P = 0.6). No DRI occurred. No WALANT-related side effects were observed.

Conclusions: WALANT protocol in CIED implantation with uninterrupted ATT reduced pro-hemostatic agents, pressure-dressing need, and hematoma size. Larger studies are needed to assess its impact on infection rates.

A 71-year-old man with a history of hypertension, type 2 diabetes mellitus, and dyslipidemia was admitted for unstable angina. He subsequently underwent coronary angiography. Approximately 2 hours after successful percutaneous coronary intervention (PCI), he reported a burning and itching sensation on his buttocks. The patient had no history of atopy or drug hypersensitivity. Physical examination revealed a bilateral erythematous, warm, tender, blistering rash localized to his buttocks [Figure 1A].

Infant botulism is a rare and potentially fatal condition caused by intestinal colonization with Clostridium botulinum. Enteric toxin causes intestinal immobility and progressive descending paralysis due to the effect on acetylcholine release at the neuromuscular junction and other cholinergic nerve terminals, particularly in the gut [1].

We present a case of infant botulism, describe the characteristics of the disease, and focus on early diagnosis.

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.

Background: Understanding medical guidelines can be challenging for patients and their families, leading to incorrect use or dosages due to inadequate or unclear explanations. Graphic organizers are tools that can help improve comprehension of medical guidelines.

Objectives: To assess the effectiveness of using designed graphic organizers to enhance comprehension of medical guidelines.

Methods: A prospective randomized controlled study was conducted at Soroka University Medical Center between 2015 and 2017. Parents of children aged 1–7 years, admitted for asthma exacerbation requiring the use of an inhaler with a spacer or for febrile convulsion requiring rectal diazepam, were enrolled. Participants were randomly assigned to receive instructions through a graphic organizer (intervention group) or plain text (control group). An assessment form was administered to evaluate the understanding of the correct steps for using the inhaler with a spacer or administering rectal diazepam. A follow-up telephone assessment was conducted after 30–60 days to evaluate recollection.

Results: Seventy-four parents with similar demographic characteristics were enrolled (intervention group [38], control group [36]). There was no significant difference in comprehension between the two groups when using medical guidelines for the two interventions. However, there was a correlation between maternal education level and long-term recollection, with an average score of 24%, 42%, and 48% among mothers with less than 8 years, 8–12 years, and over 12 years of education, respectively (P = 0.004).

Conclusions: The use of graphic organizers did not improve parent comprehension of pediatric medical guidelines. However, long-term recollection was positively correlated with maternal education level.

A full-term 1-month-old female was brought to our pediatric emergency department (ED) due to 3 days of increasing respiratory distress. She was born at term to healthy, consanguineous (2nd degree) Bedouin parents after a pregnancy that lacked adequate monitoring. At birth, a physical examination revealed an imperforate anus and a recto-vestibular fistula, left hydronephrosis, large patent ductus arteriosus (PDA), and an atrial septal defect (ASD). The diagnosis of VACTER association was made. Importantly, she had no respiratory difficulties, nor hemivertebra or tethered cord.

On admission to the ED, she presented with severe respiratory distress, tachypnea, dyspnea, and hypoxemia without evidence of upper airway obstruction or stridor. Due to impending respiratory failure, she was transferred to the pediatric intensive care unit and started on non-invasive respiratory support through a high-flow nasal cannula (HFNC), which partially relieved her work of breathing. The nasal swab for respiratory viruses was positive for enterovirus, and her urine culture grew Escherichia coli. She was transferred to the pediatric ward after clinical improvement on day 3. Echocardiography performed for evaluation of pulmonary hypertension estimated normal pressures but revealed a vascular ring anomaly. A computed tomography (CT) angiography performed confirmed the presence of an aberrant left pulmonary artery also referred to as a left pulmonary artery sling (LPAS) [Figure 1A].

Background: On 7 October 2023, an armed conflict erupted between Hamas and Israel, leading to numerous combat casualties.

Objectives: To describe computed tomography (CT) findings of combat casualties at a tertiary medical center during the first 3 months of the conflict.

Methods: A retrospective observational study was conducted on patients admitted between 7 October 2023 and 7 January 2024. Adults with conflict-related trauma who underwent chest, abdomen, and pelvis (body) trauma protocol CT scans were included.

Results: Of 272 patients who underwent body trauma protocol CT, 112 combat-related adults were included, mean age of 27 years and one female. In total, 82 patients (73%) underwent additional scans of the head and neck or extremities. Fractures were observed in 53 patients (47%). Vascular injuries were present in 40 patients (35%). Limb injuries were most common, affecting 37 patients (33%), which prompted a protocol update. Lung injuries were the most common in body CT: 30 patients (27%). Head and neck injuries were seen in 21 patients (18%). Multisystem trauma was present in 24 patients (21%). A total of 83 patients (74%) underwent surgery, mostly orthopedic/soft tissue surgeries (63%); 15 (13%) underwent abdominal surgery, with bowel injuries confirmed in eight cases.

Conclusions: CT scans are an important tool in conflict trauma management. Limb injuries were the most frequent, necessitating protocol adjustments. Lung injuries were the most common body injury; 21% of patients had multisystem trauma. Most patients required surgery.

Background: Prognostication is complex in patients critically ill with coronavirus disease 2019 (COVID-19).

Objectives: To describe the natural history of ventilated critical COVID-19 patients.

Methods: Due to our legal milieu, active withdrawal of care is not permitted, providing an opportunity to examine the natural history of ventilated critical COVID-19 patients. This retrospective cohort included COVID-19 ICU patients who required mechanical ventilation. Respiratory and laboratory parameters were followed from initiation of mechanical ventilation for 14 days or until extubation, death or tracheostomy.

Results: A total of 112 patients were included in the analysis. Surviving patients were younger than non-survivors (62 years [range 54–69] vs. 66 years [range 62–71], P = 0.01). Survivors had a shorter time to intubation, shorter ventilation duration, and longer hospital stay. Respiratory parameters at intubation were not predictive of mortality. Nevertheless, on ventilation day 10, many of the ventilatory parameters were significantly better in survivors. Regarding laboratory parameters, neutrophil counts were significantly higher in non-survivors on day 1 and C-reactive protein levels were significantly lower in survivors on day 10. Modeling using a generalized estimating equation showed small dynamic differences in ventilatory parameters predictive of survival.

Conclusions: In ventilated COVID-19 patients when there is no active care withdrawal, prognostication may be possible after a week; however, differences between survivors and non-survivors remain small.

Background: Little is known about audiovestibular function in psoriasis, a chronic systemic inflammatory disease that affects 2% of the world’s population.

Objective: To investigate audiovestibular function in patients with psoriasis.

Methods: In this prospective case-control trial, we enrolled 33 patients with psoriasis and 30 healthy controls. Audiologic testing included audiometry, tympanometry, and otoacoustic emissions recording. The vestibular investigation consisted of a dizziness handicap inventory questionnaire, a complete clinical vestibular examination, and video head impulse testing.

Results: The psoriasis group showed significantly higher average hearing thresholds in both ears at all frequencies. Otoacoustic measurements differed significantly at 3000 Hz in the right (P = 0.026) and left ear (P = 0.034). The average dizziness handicap score was considerably higher in the psoriasis group, with a mean difference of 7.70 (P = 0.025). The number of patients with abnormal right anterior semicircular canal gain values was significantly higher in the psoriasis group (P = 0.047). Saccade analysis in the psoriasis group showed significantly higher number of patients with covert corrective saccades of the left posterior canal (P = 0.037) and significantly higher number of patients with abnormal interaural difference of corrective saccades in the plane of the right anterior-left posterior canals (P = 0.035).

Conclusions: The study demonstrates an association between psoriasis and audiovestibular impairment, which can affect quality of life. These results suggest that patients with psoriasis may be evaluated with audiometry for possible hearing loss. Vestibular testing may be pursued as clinically indicated.
