Background: Prophylactic intravenous antibiotics are not routinely administered prior to direct peroral cholangiopancreatoscopy. The frequency of post-procedure bacteremia has not been well studied.

Objectives: To evaluate the risk of bacteremia following endoscopic retrograde cholangiopancreatography (ERCP) with cholangiopancreatoscopy. To assess the prevalence of other infectious complications and the effect of real-life practices regarding prophylactic antibiotic administration.

Methods: We conducted a retrospective analysis on consecutive patients (2016–2022) who underwent cholangiopancreatoscopy using the single-operator SpyGlass System (Boston Scientific Corporation, USA). Prophylactic antibiotic treatment was administered based on clinical discretion. Demographic and clinical data, including procedure indication, procedure reports, blood culture results, pre- and post-procedure antibiotic treatment, hospital length, mortality, and infectious and non-infectious complications, were collected.

Results: Our single-center cohort included 75 patients who underwent ERCP with direct cholangiopancreatoscopy. We involved 63 patients in the analysis. In 17/63 patients (27%), post-procedural blood cultures were drawn based on clinical suspicion of infection. Positive cultures were found in 4/17 (23.5%) of all cultures and 4/63 (6.3%) of the entire cohort; 2/63 (3.2%) had clinically significant bacteremia. Antibiotic prophylaxis was administered to 35 patients (55.6%), with no evidence of significant reduction in bacteremia, cholangitis, hospitalization length, or mortality rates when compared to patients who did not receive prophylactic antibiotics (P > 0.05). Post-procedural cholangitis was observed in 5/63 patients (7.9%). There were no cases of acute cholecystitis or liver abscess.

Conclusions: The prevalence of bacteremia and cholangitis following ERCP with direct cholangiopancreatoscopy was 6.3% and 7.9%, respectively. Prophylactic antibiotics did not reduce post-procedural infectious adverse events.

Background: Diverticulitis is a common cause of acute abdominal conditions, often requiring urgent or elective surgical intervention. Both psoas muscle area (PMA) and bone mineral density (BMD) have been linked to postoperative outcomes, but their role in diverticulitis remains unclear.

Objectives: To evaluate the relationship between PMA, BMD, and their combined effect on surgical outcomes in patients undergoing colectomy for diverticulitis.

Methods: In this retrospective, single-center study, we analyzed patients who underwent colectomy for diverticulitis. PMA and BMD were measured using preoperative computerized tomography. Statistical analysis assessed the association between postoperative outcomes and PMA, BMD, and their combined product (PMA × BMD).

Results: The cohort included 66 patients; median age 68.5 years (range 34–94); 41 (62.12%) females. Of the cases, 42 (63.63%) were urgent. Postoperative complications occurred in 38 patients (57.58%). Patients who developed major postoperative complications had lower PMA (1116.74 ± 716.31 mm² vs. 1948.01 ± 0.01 mm², P = 0.02). The area under the curve (AUC) for major postoperative complications was 0.94 for BMD. The AUC for postoperative ileus was 0.73, 0.69, and 0.76 for PMA, BMD, and PMA × BMD, respectively. The AUC for 30-day mortality was 0.66, 0.7, and 0.73. The AUC for ostomy reversal was 0.71, 0.71, and 0.76.

Conclusions: PMA and BMD were associated with postoperative complications after colectomy for diverticulitis. Their combined assessment may improve predictive accuracy. Current evidence regarding the impact of body composition on surgical outcomes in diverticulitis remains limited and inconsistent. Further research is warranted.

Background: Primary achalasia is a rare disorder but a significant cause of esophageal motor dysfunction. The pathophysiology of achalasia is still unknown, although an autoimmune etiology is suspected.

Objectives: To examine the presence of autoantibodies against autonomic nervous system receptors among primary achalasia patients.

Methods: In this observational cross-sectional study, we measure the levels of serum autoantibodies targeting G protein-coupled receptors of the autonomic nervous system, including adrenergic, muscarinic, endothelin, and angiotensin receptors. The study included 40 primary achalasia patients and 40 healthy controls without known history of achalasia, autoimmune diseases, or symptoms of an esophageal motility disorder.

Results: A statistically significant low level of autoantibodies against the M2 muscarinic receptor was observed in the serum of primary achalasia patients compared with the control group (P < 0.009). When exploring the two common achalasia types, a statistically significant low level of autoantibodies against type M1, M2, and M5 muscarinic receptors was observed among type 2 achalasia patients compared to patients with type 1 achalasia.

Conclusions: The finding of reduced levels of autoantibodies targeting the M2 muscarinic receptor in the serum of primary achalasia patients provides a valuable insight into the underlying pathogenesis of the disease.

In the 1950s, ionizing radiation to the scalp was commonly used in Israel as a treatment for tinea capitis. Decades later, epidemiological studies identified an increased incidence of head and neck malignancies, particularly basal cell carcinoma, as well as intracranial tumors such as meningiomas among individuals who underwent this therapy in childhood. In addition to the oncologic risk, irradiated scalp skin presents significant reconstructive challenges due to chronic skin atrophy, hypovascularity, fibrosis, and impaired wound healing. In this study, we present our clinical experience with a modified, skin-sparing surgical protocol for managing reconstruction post excision of non-melanoma skin cancer of the scalp in patients previously irradiated for tinea capitis. The surgical strategy is tailored according to lesion size, depth, periosteal involvement, and scalp tissue quality. It incorporates components of the reconstructive ladder as appropriate. We present three representative cases highlighting key surgical challenges and considerations in this complex population.

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.

We summarized the role of lung ultrasound for diagnosing and monitoring various pediatric respiratory diseases. We began with an overview of the basics of the tool, followed by describing its use in conditions such as pneumonia, pleural effusion, bronchiolitis, atelectasis, pneumothorax, bronchiectasis, and interstitial lung disease. We highlighted the sensitivity and specificity of lung ultrasound for the various diseases described. Furthermore, we included a comparison of this modality to other commonly used imaging techniques.

Background: Prior to the coronavirus disease 2019 (COVID-19) pandemic, bronchiolitis caused by respiratory syncytial virus (RSV) was primarily observed during the winter months. Recently, however, an increase in incidence during the warmer months has been noted. This trend suggests an interaction between RSV and coronavirus, as well as the impact of public health measures, such as hand hygiene, mask-wearing, and social distancing.

Objectives: To characterize bronchiolitis cases in children under 2 years old caused by RSV during the COVID-19 pandemic in Israel from 2018 to 2022.

Methods: We conducted retrospective study by analyzing medical records of children hospitalized with bronchiolitis from January 2018 to December 2022. A comparison was made between cases before and after the first COVID-19 lockdown.

Results: A total of 922 children with bronchiolitis were studied: 276 cases occurred before the lockdown and 646 cases afterward. We found an increase in bronchiolitis frequency during the summer following the lockdown and a decrease during the winter (P < 0.0001). In addition, there was a shift in the pathogenic profile, with a notable rise in mixed infections after the lockdown (P < 0.0001). No significant differences in clinical presentation were observed between pre- and post-lockdown periods.

Conclusions: There was a change in bronchiolitis seasonality after the lockdown, with a significant increase in cases during the summer and a rise in mixed infections. Further studies are needed to assess whether this shift is a lasting consequence of the pandemic or a temporary change.

Background: Community-acquired pneumonia (CAP) is a prevalent bacterial infection in children. Lung ultrasound (LUS) is gaining popularity as a diagnostic tool for pneumonia, with the added potential for monitoring disease progression. However, research on the benefits of this modality for monitoring disease progression remains limited.

Objectives: To categorize the follow-up sonographic findings of lung inflammation in pediatric patients performed 10–14 days after being diagnosed with CAP.

Methods: We conducted a prospective observational study of children aged 0–18 years, diagnosed with CAP between 2020 and 2022. LUS findings at the time of diagnosis and 10–14 days later were recorded and documented.

Results: In total, 47 children were recruited, and 22 were included in the analysis. At the time of diagnosis, 20 patients (90%) had B-lines. Air bronchograms were found in all patients, and consolidation findings were observed in seven of the examined patients (32%). At the follow-up LUS 10–14 days later, B-lines were observed in six patients (27%). Air bronchograms were observed in eight patients, and consolidation findings were observed in six (27%). In 13 patients (59%), the follow-up LUS was completely normal. These patients were younger and had lower body weights. Pathological findings persisted in 41% of the patients.

Conclusions: For most patients, LUS demonstrated a resolution. Further large-scale studies are needed to validate the findings and determine the role of LUS in pediatric CAP.

Diabetes mellitus (DM) is a serious and growing global health challenge. The number of people diagnosed with diabetes continues to rise, and it is projected that by 2035 more than 592 million individuals worldwide will have diabetes [1]. DM can impact the heart through various mechanisms. Vascular complications are associated with diabetes and include both epicardial coronary artery and small vessel disease. Cardiomyopathy and heart failure may also occur. Insulin resistance causes cardiomyocytes to have a reduced capacity for glucose utilization, leading to increased uptake of free fatty acids. This, in turn, results in triglyceride storage and lipotoxicity, which contribute to impaired cardiac contractility [2].

Diabetes may lead to the production of advanced glycation end (AGE) products, resulting in an accumulation of reactive oxygen species. This accumulation triggers inflammation that can cause myocyte apoptosis and mitochondrial dysfunction. AGE can also contribute to cardiac fibrosis, which increases myocardial stiffness and results in heart failure with preserved ejection fraction (HFpEF) [2].

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.

Esophageal lung is a rare congenital malformation. We present a case of a full-term infant with an esophageal lung presenting as a white lung combined with VACTERL association (vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities) and dysmorphic features. A right pneumonectomy was successfully performed.

Liver transplantation (LT) remains the only definitive treatment for most types of liver failure. However, it is considered a highly technically complex surgery performed in a critically ill patient population and is, hence, associated with significant morbidity and mortality. Peroneal neuropathy with foot drop has been intermittently reported as a complication following LT, with an incidence ranging from 1.4% to 13.3% [1-4]. This debilitating condition is characterized by an inability to lift the forefoot due to paralysis or significant weakness of the dorsiflexor muscles. While it may not appear to be a serious complication, it can significantly impair gait, increase the risk of falls, and ultimately affect ambulation and the ability to perform daily activities [5].

In this case communication, we described two cases of foot drop following LT at Rabin Medical Center (Beilinson Campus), Petah Tikva, Israel. Our research joins a growing body of evidence and raises awareness about foot drop as an underreported yet debilitating complication. It underscores the importance of increased vigilance and describes our preventive measures adopted to reduce future incidents.

Background: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce.

Objectives: To study the effects of actions to limit the spread of COVID-19 on AT management.

Methods: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020–2 August 2021, group A) to a parallel period (2019–2020, group B), and a 9-year period preceding the pandemic (March 2011–February 2020, group C).

Results: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06–0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39–0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014).

Conclusions: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

Hiatal hernia is defined as a protrusion of abdominal contents through the hiatal foramen into the thoracic cavity. Etiology is presumed to be a congenital malformation, trauma, or iatrogenic like prior surgical dissection of the hiatus during surgery for esophageal or gastric etiology. Age, sex, hormonal changes, body habitus (i.e., kyphosis, scoliosis), and increased body weight are key risk factors. Most hiatal hernias are asymptomatic and discovered incidentally. Surgical repair of hiatal hernia is indicated in symptomatic patients with dysphagia, weight loss, respiratory symptoms such as aspirations, and recurrent pneumonia events [1]. Complications arising from laparoscopic repair of hiatal hernia are generally minor and do not typically necessitate surgical intervention. Major complications include pneumothorax, splenic laceration, esophageal rupture, and pericardial injury. Other complications include recurrence of hernia, vagal nerve injury, gastroesophageal reflux disease, and gastroparesis. The utilization of mesh in repair procedures introduces additional complications such as mesh migration and mesh infection. Previously reported recurrence rates following the repair of a hiatal hernia with mesh range from 10–30%. In this case communications, we presented a case involving the early recognition and treatment of postoperative cardiac tamponade.

Background: Obliterative vaginal procedures may offer lower perioperative morbidity and equal success rates as reconstructive procedures for frail and elderly women who no longer desire future coital function. The combination of vaginal hysterectomy with either reconstructive or obliterative vaginal procedures has not yet been investigated.

Objectives: To compare peri- and postoperative outcomes of vaginal hysterectomy with pelvic floor reconstruction (VHR) vs. vaginal hysterectomy with colpocleisis (VHC).

Methods: We conducted a retrospective study comparing medical and surgical data of patients undergoing either VHR or VHC between 2006 and 2015. Data were obtained from inpatient and outpatient medical records including peri- and postoperative course, as well as long-term (24 months) follow-up data.

Results: We identified 172 patients who underwent VHR and 44 who underwent VHC. Patients in the VHC group were significantly older (71.3 ± 4.5 vs. 68.6 ± 6.5 years, P = 0.01), and more likely to have medical co-morbidities (P = 0.001 and P = 0.029, respectively). Patients in the VHC group experienced shorter operative time (2.3 ± 0.58 vs. 2.7 ± 1.02 hours, P = 0.007), lower perioperative blood loss (P < 0.0001), shorter hospital stay (P < 0.0001), and lower rates of postoperative urinary retention. Long-term pelvic organ prolapse (POP) recurrence rates were significantly higher among the VHR group. Postoperative resolution of both stress urinary incontinence and overactive bladder were common in both groups.

Conclusions: VHC is associated with lower perioperative blood loss, shorter operative time, shorter hospital stay, shorter time with an indwelling catheter, and lower long-term objective POP recurrence rates.
