Background: The continuity equation (CE) used for evaluating aortic stenosis (AS) is based on values obtained from transthoracic echocardiography (TTE) with the assumption that the left ventricular outflow tract (LVOT) has a circular shape. Transesophageal echocardiography (TEE) may be used for accurate measurement of the LVOT cross-sectional area (CSA). Previous studies have focused on fusion from TEE for LVOT-CSA measurement and TTE for velocity time integrals (VTI) calculations.

Objectives: To assess aortic valve area (AVA) using parameters obtained exclusively from TEE as an alternative approach.

Methods: Thirty patients with equivocal AS based on TTE were evaluated using TEE for further assessment.

Results: The mean pressure gradient across the aortic valve (AV) was 38 ± 5.9 and 37.9 ± 7.6 mmHg in TTE and TEE, respectively, P = 0.42. LVOT-CSA was larger in TEE (3.6 ± 0.3 vs. 3.4 ± 0.3 cm², P = 0.049). VTI over the AVA was similar (98.54 ± 22.8 and 99.52 ± 24.52 cm in TTE and TEE, respectively, P = 0.608), while VTI across the LVOT was higher when measured by TTE (24.06 ± 5.8 vs. 22.03 ± 4.3 cm, P < 0.009). Using the CE, AVA was 0.82 ± 0.3 vs. 0.83 ± 0.17 cm² in TEE vs. TTE, respectively, P = 0.608. Definitive grading was achieved in all patients (26 patients defined with severe AS and 4 with moderate).

Conclusions: In equivocal cases of AS, full assessment using TEE may be a reliable modality for decision making.

Background: In the past decade, numerous new imaging and laboratory tests have been implemented that significantly contribute to improved medical diagnostic capabilities. However, inappropriate utilization, which occurs on a large scale, has significant ramifications for both patient care and health systems.

Objectives: To assess the impact of a novel clinical decision support system (CDSS) applied to our electronic medical records on abdominal ultrasonography utilization pattern.

Methods: We conducted a retrospective cohort study comparing patterns of abdominal ultrasound utilization in cases of liver enzyme elevation, with and without CDSS, between February and May in 2017 (before CDSS implementation) and during the same months in 2018 (after CDSS implementation). The following parameters were collected: number of tests ordered according to the guidelines, tests with a diagnostic value, and order forms completed with any data or a diagnostic question. The comparison was conducted using chi-square test.

Results: Of 152 abdominal ultrasound tests, 72 were ordered in the pre-implementation period and 80 in the post-implementation period. The system failed to reach statistical significance regarding the rates of ordered tests according to the guidelines and/or tests with a diagnostic value. However, the use of the CDSS had a statistically significant impact regarding completing the order form with data, including a specific diagnostic question.

Conclusions: The effect of the system on the efficiency of test utilization was partial. However, our findings strongly suggested that CDSS has the potential to promote proper usage of complementary technologies.

Cognitive impairment due to different types of anemia is well-known. We reviewed the links between different types of anemia and the mechanism of cognition impairment as well as the direct involvement of micronutrients such as iron, vitamin B12, folic acid, and copper on cognitive function. Anemia can lead to cognitive impairment, yet the current health policy usually requires patient involvement in the treatment decision-making. Therefore, can an anemic patient be a partner to shared decision-making concerning the recommended treatment?

Background: In 2019, 1 mg subcutaneous semaglutide was registered for the treatment of diabetes in Israel. Recognition of its effect on weight has led to its use as a treatment for obesity.

Objectives: To explore physicians’ pre-therapy considerations, therapy practices, and attitudes regarding subcutaneous semaglutide for weight loss.

Methods: A 22-item questionnaire was disseminated to physicians who prescribed semaglutide 1-mg for weight loss using an authorized off-label path.

Results: In total, 127 physicians completed the questionnaire. As for pretreatment requirements, in the absence of diabetes, 30% requested a minimal body mass index of 30 kg/m². Additional requirements were documented lifestyle-change effort (67%) and prior weight loss medication use (13%). Half of the physicians regarded calorie restriction, and 23% considered physical activity as necessary for weight loss while on therapy. As for dose, most physicians (78%) started with a 0.25-mg weekly injection, 57% doubled the dose monthly, and all others recommended doubling when side effects subsided. Regarding weight loss goal, 43% of the physicians set a personal goal with each patient while 26% limited the goal to 10% of initial weight. Fewer than 50% of physicians discussed treatment duration with their patients, and 52% of patients discontinued therapy in the first 3 months. The main reasons for discontinuation were price, lack of effect, and fear of long-term side effects.

Conclusions: The diverse approaches regarding off-label use of semaglutide for weight reduction highlight the necessity to guide physicians and standardize treatment regimen.

Background: In recent years, major progress has been made in treating the wet form of age-related macular degeneration (AMD) with anti-vascular endothelial growth factors, which reportedly stabilize and improve vision.

Objectives: To examine the effect of dietary supplementation, as recommended by the Age-Related Eye Disease Study 2 (AREDS2), on the number of anti-vascular endothelial growth factor injections administered to patients with wet AMD.

Methods: A retrospective study was conducted with 57 participants (27 participants in the study group and 30 in the control group) receiving injections of anti-vascular endothelial growth factors. The study group received dietary supplements for at least one year before the treatment was initiated, while the control group did not. Primary outcome was the number of injections a patient received over a 3-year period. Secondary outcomes were central macular thickness and visual acuity.

Results: The average number of injections per patient after 3 years was 21.89 ± 7.85 in the study group and 26.00 ± 5.62 in the control group (P = 0.083). Final visual acuities were 0.45 ± 0.45 and 0.8 ± 0.73 (P = 0.09), and final central macular thicknesses were 288.26 ± 55.38 and 313.12 ± 107.36 (P = 0.38) in the study and control groups, respectively.

Conclusions: The average number of injections after 3 years was lower in the study group, but this difference did not reach statistical significance. No statistically significant difference was found in final visual acuity or central macular thickness between the groups.

Background: The French AmbUlatory Cesarean Section (FAUCS) technique was introduced to the Galilee Medical Center in September 2021. FAUCS was performed electively for interested women who meet the criteria.

Objectives: To evaluate the learning curve of senior surgeons performing FAUCS, the procedure short-term outcomes, and complications.

Methods: This retrospective study included 50 consecutive women who underwent FAUCS from September 2021 until March 2022 at our facility. Preoperative, intraoperative, postoperative, and demographic data were retrieved from patient electronic charts.

Results: The mean duration of surgery was 53.26 ± 11.62 minutes. This time decreased as the surgical team's experience increased: from a mean 58.26 ± 12.25 minutes for the first 15 procedures to a mean 51.17 ± 9.73 minutes for subsequent procedures. The mean visual analogue scale score for 24 hours was 1.08 ± 0.84 (on a 10-point scale). The rate of neonatal cord pH < 7.2 was 6%, and there were 11.3% cases of vacuum assisted fetal extraction. In total, 44% of the women were able to mobilize and urinate spontaneously by 4–6 hours. Complications included bladder injury (n=1), endometritis (n=1), and incisional hematoma (n=1). Overall, the maternal satisfaction rate was high; 94% of the women would recommend FAUCS to others.

Conclusions: FAUCS is a feasible procedure with a high satisfaction rate. Following the first 15 procedures performed by one surgical team, the operative time decreased considerably. Further randomized controlled studies are needed to compare this procedure to regular cesarean section and evaluate neonatal outcomes.

Psoriatic arthritis can present with significant hand and wrist deformity and dysfunction [1]. The development of newer biological therapies has resulted in higher rates of remission [2]. However, surgical intervention is still indicated in pain, disability, and severe deformation cases. The management of patients with rheumatic diseases has a controversial history, characterized by rheumatologists and hand surgeons debating the efficacy of surgical interventions. Some surgeons attribute the controversial results to “too little and too late” referral of patients from rheumatologists [3]. While the availability of new and more effective medication has changed the indications and postponed surgical intervention, it is important to remember that surgery is often more effective when used preventively in the early stages than when forced to salvage. In the following case, we present a patient with psoriatic arthritis who presented with advanced-stage debilitating hand deformity and was treated surgically.

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.

Background: During combined phacovitrectomy, it is common practice to suture the main corneal incision to prevent intraoperative and postoperative wound leak. However, it may be possible to avoid suturing using a self-sealing corneal incision technique as in standard cataract surgery.

Objectives: To evaluate the clinical outcome, safety, and complications of combined phacovitrectomy without preventive suturing.

Methods: This retrospective case series study included consecutive patients who underwent combined phacovitrectomy between January 2018 and June 2019 for mixed indications. Surgeries were performed at a tertiary university hospital. All surgeries were performed by the same two retinal surgeons. Cataract surgery was performed first, followed by insertion of trocars and vitrectomy. Corneal sutures were not planned but were used at the discretion of the surgeon.

Results: The cohort included 106 eyes of 102 patients. Suturing of the main corneal incision was deemed necessary in five cases (5%) because of a main incision leak or anterior chamber shallowing during trocar insertion. No other complications related to the absence of prophylactic corneal sutures were encountered during surgery or follow-up.

Conclusions: Preventive corneal suturing may not be necessary in combined phacovitrectomy surgery and can be used in the few cases in which it is indicated during surgery.

Background: Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] ³ 50 kg/m²) are scarce.

Objectives: To compare perioperative morbidity and long-term outcomes between patients with SO and non-SO (NSO).

Methods: Patients with SO who underwent primary bariatric surgery with a follow-up ³ 5 years were age- and gender-matched with NSO patients in a retrospective, case-control study. Data included demographics, BMI, co-morbidities, early outcomes, current and nadir weight, co-morbidity status, and general satisfaction.

Results: Of 178 patients, 49.4% were male, mean age 44.5 ± 14 years. Mean preoperative BMI was 54.7 ± 3.6 and 41.8 ± 3.8 kg/m² in SO and NSO, respectively (P = 0.02). Groups were similar in preoperative characteristics. Depression/anxiety was more prevalent in NSO (12.4% vs. 3.4%, P = 0.03). Obstructive sleep apnea was higher in SO (21.3% vs. 10.1%, P = 0.04). Sleeve gastrectomy was performed most often (80.9%), with a tendency toward bypass in SO (P = 0.05). Early complication rates were: 13.5% in SO and 12.4% in NSO (P = 0.82). Mean follow-up was 80.4 ± 13.3 months. BMI reduction was higher in SO (31.8 ± 5.9 vs. 26.8 ± 4.2 kg/m², P < 0.001) and time to nadir weight was longer (22.1 ± 21.3 vs. 13.0 ± 12.0 months, P = 0.001). Co-morbidity improvement and satisfaction were similar.

Conclusions: Patients with SO benefited from bariatric surgery with reduced BMI and fewer co-morbidities. No added risk of operative complications was found compared to patients with NSO.

Adenoid surgery (adenoidectomy) is one of the most common pediatric surgical procedures. Complications of this surgery include anesthetic issues, bleeding, pain, dysphagia, and velopharyngeal insufficiency. The intraoperative complications are usually the most urgent and therefore require prompt identification and resolution. Tension pneumothorax (TPX) is a rare intraoperative. We present the first case in the English literature, to the best of our knowledge, of TPX during adenoid/tonsil surgery.

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.

Biological therapies with monoclonal antibodies have revolutionized the management of many inflammatory and autoimmune diseases. Combining biological treatments is very rarely indicated and may theoretically result in severe adverse effects, specifically, an increased tendency toward infectious diseases. We present the case of a woman in whom combination therapy with canakinumab for familial Mediterranean fever (FMF) and mepolizumab for chronic eosinophilic pneumonia was successfully employed.

Background: Morbidly adherent placentation (MAP) increases the risk for obstetric hemorrhage. Cesarean hysterectomy is the prevalent perioperative approach. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive and relatively simple endovascular procedure to temporarily occlude the aorta and control below diaphragm bleeding in trauma. It has been effectively used to reduce obstetric hemorrhage.

Objectives: To evaluate whether REBOA during cesarean delivery (CD) in women with morbidly adherent placentation is a safe and effective treatment modality.

Methods: We introduced REBOA for CD with antepartum diagnosis of MAP in 2019 and compared these patients (RG) to a standard approach group (SAG) treated in our center over the preceding year, as a control. All relevant data were collected from patient electronic files.

Results: Estimated blood loss and transfusion rates were significantly higher in SAG; 54.5% of SAG patients received four RBC units or more vs. one administered in RG. No fresh frozen plasma, cryoprecipitate, or platelets were administered in RG vs. mean 3.63, 6, and 3.62 units, respectively in SAG. Ten SAG patients (90.9%) underwent hysterectomy vs. 3 RG patients (30%). Five SAG patients (45%) required post-surgical intensive care unit (ICU) admission vs. no RG patients. Bladder injury occurred in five SAG cases (45%) vs. 2 RG (20%). One RG patient had a thromboembolic event. Perioperative lactate levels were significantly higher in SAG patients.

Conclusions: Use of REBOA during CD in women with MAP is safe and effective in preventing massive bleeding, reducing the rate of hysterectomy, and improving patient outcome.

Background: Abdominal pathology in pregnant patients is a frequent challenge for emergency department physicians. Ultrasound is the imaging modality of choice but is inconclusive in approximately one-third of cases. Magnetic resonance imaging (MRI) is becoming increasingly available, even in acute settings. Multiple studies have defined the sensitivity and specificity of MRI in this population.

Objectives: To evaluate the use of MRI findings in pregnant patients presenting with acute abdominal complaints to the emergency department.

Methods: This retrospective cohort study was conducted at a single institution. Data were collected on pregnant patients who underwent an MRI for acute abdominal complaints between 2010 and 2019 at a university center. Patient demographics, diagnosis at admission, ultrasound and MRI findings, and discharge diagnosis were recorded and evaluated.

Results: In total, 203 pregnant patients underwent an MRI for acute abdominal complaints during the study period. MRI was found without pathology in 138 cases (68%). In 65 cases (32%), the MRI showed findings that could explain the patient's clinical presentation. Patients presenting with long-standing abdominal pain (> 24 hours), fever, leukocytosis, or elevated C-reactive protein values were at a significantly increased risk of having an acute pathology. In 46 patients (22.6%), MRI findings changed the primary diagnosis and management while in 45 patients (22.1%) MRI findings improved characterization of the suspected pathology.

Conclusions: MRI is helpful when clinical and sonographic findings are inconclusive, leading to changes in patient management in more than one-fifth of patients.
