Background: Rising rates of antibiotic resistance pose a major challenge in the treatment of Helicobacter pylori (H. pylori) infection. Current treatment guidelines emphasize the importance of acquiring local resistance data to select an effective empirical regimen.

Objectives: To analyze trends in H. pylori antibiotic resistance over two decades in Israel.

Methods: Data from Clalit Health Services for H. pylori isolates cultured from gastric biopsies between January 2007 and December 2023 were included. Susceptibility to clarithromycin, amoxicillin, metronidazole, tetracycline, and levofloxacin was determined using E-tests. Demographic and clinical variables were retrieved to identify predictors of resistance.

Results: We identified 2521 H. pylori isolates (71.6% females, mean age 44.4 ± 15.8 years). Most individuals were residents of central Israel (84.6%) and of Jewish ethnicity (87.8%). Antibiotic resistance was observed in 71.6% of isolates for clarithromycin, 64.3% for metronidazole, and 19.4% for levofloxacin. Resistance to tetracycline and amoxicillin was minimal (0.2% and 1.2%, respectively). Dual clarithromycin-metronidazole resistance occurred in 50.4%, and triple resistance (clarithromycin-metronidazole-levofloxacin) was found in 12.0%. Between 2007 and 2012, clarithromycin resistance increased 5.3% annually, then tapered (odds ratio [OR] 1.05, 95% confidence interval [95%CI] 3.84–6.85, P < 0.001). Age and prior antibiotic use were predictors of resistance for all antibiotics, with the greatest effect observed for drugs in the same class. Female sex was associated with higher resistance to levofloxacin (OR 1.62, 95%CI, 1.28–2.05, P < 0.001).

Conclusions: Antibiotic resistance to H. pylori is high in our geographical region. Nevertheless, resistance rates have remained steady over recent years.

Background: Ramadan, one of the core tenets of Islam, requires a rigorous fasting regimen from dawn until sunset, during which practitioners abstain from all forms of food and drink. This substantial alteration in daily habits raises pertinent questions regarding its potential implications for cardiovascular health.

Objectives: To analyze the incidence of myocardial infarction (MI) throughout the Ramadan fasting period.

Methods: We retrospectively compared the incidence of MI occurring during Ramadan with that observed during the corresponding non-Ramadan months from 2010 to 2021 using medical records of Muslim patients admitted to the Galilee Medical Center. Ramadan's timing varies from year to year. We used a 3-year comparative framework to ensure seasonal alignment.

Results: During the study period and within a well-defined geographic region, we found that among Muslims, there were 405 MIs: 201 during Ramadan and 204 during non-Ramadan periods, P = 0.282.

Conclusions: The incidence of MI during Ramadan remained stable, indicating that the fasting practice does not significantly heighten the risk of MI.

Background: Locally advanced gastric adenocarcinomas are treated with neoadjuvant chemotherapy, surgery, and adjuvant chemotherapy. Since 2019 the standard of care for perioperative chemotherapy has been FLOT protocol. Concerns regarding the use of FLOT in elderly patients ≥ 65 years of age emerged due to the relatively high toxicity of this protocol.

Objectives: To evaluate the toxicity profile of FLOT and clinical outcome in elderly patients.

Methods: We conducted a retrospective analysis of patients with locally advanced gastric adenocarcinomas treated with FLOT between 2017–2023 at the Sheba Medical Center. The cohort was stratified by age (≥ or < 65 years). The primary outcome was overall survival (OS). Secondary outcomes were treatment-related toxicity. Kaplan-Meier analysis and Cox proportional hazard regression model were used to analyze the effect of exposure variables on OS.

Results: The study cohort included 91 patients. The median age was 60 years (IQR 50–67); 32 patients were included in the ≥ 65 years group, and 59 patients were included in the < 65 years group. Median follow-up was 40 months (IQR 17–58). Patients ≥ 65 years old received fewer cycles of FLOT compared to those < 65 years old (4.5 vs. 7 cycles, respectively, P = 0.03). Despite the difference in treatment intensity and cumulative chemotherapy dose, there was no difference in median OS between patients ≥ 65 years old compared with those < 65 years old (P = 0.68).

Conclusions: Elderly patients with locally advanced gastric adenocarcinomas received fewer cycles of perioperative FLOT without compromising clinical outcomes.

Pre-Ramadan fasting planning before the month of Ramadan represents a golden opportunity for better glucose control during the month of Ramadan among patients with type 2 diabetes mellitus (T2DM). Pre-Ramadan begins 1–2 months earlier and represents a crucial period when healthcare practitioners can provide medical instructions, risk assessment, and stratification to minimize the associated risks such as postprandial hyperglycemia and hypoglycemia during Ramadan fasting. This review focuses on two important classes of drugs that are widely used in Israel incretin-based therapy, particularly the glucagon-like peptide-1 receptor (GLP-1Rc) agonists class and the sodium-glucose cotransporter-2 inhibitors (SGLT-2i) class. In addition, we provide data regarding specific populations such as elderly patients and Bedouins living in the Negev area who require specific recommendations for safe Ramadan fasting. Our data are based on previously published guidelines, consensus statements, and our experience.

Background: Modern medicine has improved survival rates in burn care. However, this progress has led to a new challenge of sepsis, which has become the leading cause of death in burn patients, accounting for over 50% of mortality. The diagnosis and treatment of sepsis in the burn care unit pose significant challenges due to the hypermetabolic state of the patient, which can mask septic signs and symptoms. This situation underscores the urgent need for improved strategies in sepsis management in burn patients.

Objectives: To assess the predictors of morbidity and mortality among severe burn patients.

Methods: Rambam Health Care Campus is the referral center for burn patients in northern Israel. We reviewed 5 years of patient records, noting information regarding sepsis, laboratory results, infections, and overall morbidity and mortality. In addition, a comparative cohort of burn patient records without sepsis was compared.

Results: Thirty patients had recorded sepsis. Total and direct bilirubin were associated with higher mortality (P < 0.05). Elevated white blood cell count and platelet count at admission were also associated with mortality (P < 0.05). The most prominent burn areas were the arms, head, and legs. The leading cause of injury was fire, followed by an explosion. Burns of total body surface area ≥ 40% was associated with sepsis.

Conclusions: Sepsis is a complex challenge when diagnosing and treating burned patients. Identifying specific traits and prognostic factors is crucial to adequately treat these patients. Research in burn care and sepsis management is essential.

Background: Soft-tissue defects of the lower limb pose a reconstructive challenge. Soft tissue loss with exposed bone, tendon, or cartilage often requires free flap reconstruction. Dermal substitutes are used for treatment of extensive burns to replace damaged skin and may be ideal for lower limb reconstruction in selected cases.

Objectives: To present our experience with reconstruction of lower limb wounds using Integra® Bilayer Wound Matrix (Integra LifeSciences Corp., Plainsboro, NJ, USA) and MatriDerm® (MedSkin Solutions Dr. Suwelack AG, Billerbeck, Germany).

Methods: This single center retrospective study comprised 10 patients who underwent reconstruction of extensive tissue defects of the distal lower limbs with dermal matrices and split-thickness skin grafts.

Results: All patients were successfully reconstructed and resumed normal ambulation. Six patients had complete and four partial graft takes that was treated conservatively until full wound healing. Older patients with medical co-morbidities or history of wound infection were more likely to have partial graft take. One postoperative infection was recorded in the study.

Conclusions: Dermal substitutes are easy to apply and safe, show minimal donor site morbidity, provide good functional and aesthetic outcomes, and should be used for reconstruction of complex lower limb wounds.

Background: Abdominoplasties are among the most common procedures in aesthetic plastic surgery. The target audience are patients after massive weight loss who are left with excess skin and post-partum patients. Due to the efficacy of abdominoplasties in improving the abdominal contour, it became a mainstay procedure in plastic surgery. Claims have been made that abdominal surgeries can be safely combined with breast surgeries, and thereby decrease the risk associated with anesthesia for two separate procedures as well as the recovery period. The benefits of the combined procedures led to a surplus of patients seeking consultations.

Objectives: To examine the safety of the mommy makeover procedure compared to sole abdominoplasty.

Methods: Patients who previously underwent abdominoplasty by the senior author were divided into two groups based on whether breast surgery was performed in addition to the abdominoplasty. Groups were compared based on demographical, clinical, and surgical variables.

Results: The study cohort included 726 patients, of whom 15% underwent "Mommy-makeovers". Groups differed only in liposuction volume, resection weight and number of drains. Regarding surgical outcomes, surgical site infections were seen at a greater rate in the isolated abdominoplasty procedure. Further analyses accounting for potential confounders found no difference between the groups in terms of adverse events.

Conclusions: Mommy makeovers do not display a safety concern when compared to isolated abdominoplasties. Surgeons must consider various patient characteristics to ensure optimal results.

Background: Identifying drug–drug interactions (DDIs) in dermatology can be cumbersome and time-consuming using traditional methods.

Objectives: To explore the potential of ChatGPT-4o, an artificial intelligence (AI)-based chatbot, to streamline the identification process.

Methods: ChatGPT-4o was tasked with assessing DDIs among commonly prescribed dermatological medications. The accuracy and reliability of the chatbot's outputs were compared against established references for 43 interactions.

Results: ChatGPT-4o successfully identified all evaluated interactions. It accurately described the interaction effects in 42 cases, with only one example of misdescription.

Conclusions: The findings highlight the potential of ChatGPT to serve as an effective and efficient alternative for identifying and understanding DDIs in dermatology, despite one noted error that emphasizes the need for ongoing verification against trusted references. Further research is needed to validate its use across a broader range of medications and clinical scenarios.

Psoriasis is a chronic, immune-mediated skin disease characterized by inflammatory lesions and systemic co-morbidities. Emerging evidence highlights the significant role of the microbiome in psoriasis pathogenesis. Dysbiosis of the skin and gut microbiota has been linked to increased disease severity and co-morbidities such as psoriatic arthritis and cardiovascular disease. In this review, we explored the microbiome's influence on immune responses in psoriasis and its potential as a therapeutic target. Microbial therapies, such as probiotics and fecal microbiota transplantation, hold promise for restoring microbial balance and improving outcomes. We also discuss how the microbiome modulates drug efficacy and toxicity, offering insights for personalized treatment approaches. While challenges remain in establishing causality and translating findings into clinical practice, leveraging the gut-skin axis may optimize psoriasis management and improve patient outcomes.

Pott’s Puffy tumor (PPT) is a rare complication of frontal sinusitis, involving a subperiosteal abscesses with associated osteomyelitis of the frontal sinus anterior table. It mainly affects children and adolescents but can also occur in adults. It presents with localized forehead swelling, pain, fever, headache, and sometimes intracranial complications like epidural or subdural abscesses [1,2]. The standard treatment for PPT typically involves surgical drainage under general anesthesia and broad-spectrum intravenous antibiotics. During the coronavirus disease 2019 (COVID-19) pandemic (March–June 2020), delayed surgeries and resource limitations led to the use of minimally invasive techniques [3] such as needle aspiration without general anesthesia. In this study, we present three adult PPT cases from Nottingham University Hospitals, United Kingdom, treated with early abscess aspiration during this period.

We conducted retrospective study of PPT cases presented during the early COVID-19 pandemic. Following patients’ consent, case notes were reviewed for baseline demographics, previous treatments, presenting symptoms, and examination findings.

Standup paddleboard surfing (SUP) is a sports activity in which a person stands upright on a surfboard and propels the board using a single paddle. It is an emerging recreational activity that is attracting public attention and gaining popularity because it promotes fitness, strength, and improved balance. In this review, we discuss the outcomes after severe cardiac events in SUP surfers. We report on six fit individuals (five males and one female, age range 41–69 years) who experienced sudden cardiac arrest (n=3) or acute myocardial infarction occurring during SUP. Cardiopulmonary resuscitation was initiated in three patients on presentation due to ventricular fibrillation. In four patients the culprit coronary artery was the left anterior descending artery treated by percutaneous coronary intervention. All patients were discharged alive. A review of the literature showed a paucity of scientific evidence to substantiate the proposed health benefits of SUP surfing. Our cluster of acute cardiac events occurring during this activity calls for heightened public awareness to better understand the physical demand required to practice SUP. There is a need for more data regarding the cardiovascular clinical aspects of this water activity, and the risks it entails.

Nail-patella syndrome (NPS, OMIM: #161200), also known as Fong disease, hereditary osteo-onychodysplasia (HOOD), and Turner-Kieser syndrome, is a rare pleiotropic, multisystemic condition with an estimated incidence of 1 per 50,000. It is characterized mainly by developmental defects of dorsal limb structures due to symmetrical mesodermal and ectodermal abnormalities. It manifests as a classic clinical tetrad of distal digital abnormalities and fingernail dysplasia, which are typically bilateral and symmetrical, hypoplasia or absence of the patella, presence of iliac horns, and elbow deformities. It can also affect other structures (e.g., tendons, ligaments, and muscles), and may impact ophthalmic (glaucoma, increased ocular pressure and subsequent blindness), renal (nephropathy), neurological, orthopedic, and gastrointestinal systems. NPS can lead to sensorineural hearing loss and vasomotor problems [1,2]. Clinical manifestations vary greatly in frequency and severity. The prognosis is relatively good when clinical features are mild and cause no disability. However, serious and even life-threatening complications can occur. NPS is usually clinically diagnosed based on physical examination and radiological imaging. Genetic testing and renal biopsy can also assist in diagnosis confirmation.

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].

Gaucher disease (GD) is an inherited autosomal recessive genetic disorder caused by mutations in the glucocerebroside (GBA1) gene [1]. These variants result in decreased activity of the lysosomal enzyme β-glucocerebrosidase (GCase), which is essential for breaking down glucocerebroside into glucose and ceramide. Consequently, activated macrophages, known as Gaucher cells, accumulate undegraded glucocerebroside. The phagocytic role and naturally high-level GCase activity of macrophages may partly explain why these cells are particularly affected in GD. The accumulation of glucocerebroside in macrophages causes an expansion in the population of these cells, leading to symptoms like hepatosplenomegaly, thrombocytopenia, anemia, bleeding tendency, growth retardation, and bone issues. Bone marrow infiltration may result in bone infarction, episodes of bone crises, and osteonecrosis, mainly of large joints and less commonly as pathological fractures. These latter skeletal complications are the most critical irreversible consequence of untreated GD, significantly impacting the quality of life of patients, and hence should be avoided by early administration of specific therapy. The accumulation of glucocerebroside in lysosomes has been linked to a pro-inflammatory state [2]. In addition, the misfolding and retention of mutant GCase within the endoplasmic reticulum (ER) has been associated with ER stress and activation of the unfolded protein response, contributing to GD phenotypic heterogeneity, inflammation, and immune dysregulation [3].

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.
