Background: Although minimally invasive surgery for Crohn’s disease has been validated in previous studies, most of those reports have referred to laparoscopic-assisted procedures with an extra-corporeal anastomosis.

Objectives: To evaluate the short- and long-term outcomes of total laparoscopic ileocolic resection with an intracorporeal anastomosis for Crohn’s disease patients.

Methods: We conducted a single-center retrospective review of all patients who underwent primary ileocolic resection for Crohn’s disease between 2010 and 2021. Group A included 34 patients who underwent total laparoscopic ileocolic resection with intracorporeal anastomosis. Group B comprised 144 patients who underwent an open or laparoscopic-assisted procedure.

Results: No differences were noted in operative time (mean 167 minutes vs. 152 minutes, P = 0.122), length of stay (median 6.4 days vs. 7.5 days, P = 0.135), readmission rates (11.8% vs. 13.2%, P = 1), and microscopic involvement of surgical margins (7.7% vs. 18.5%, P = 0.249). Group A had significantly fewer postoperative surgical site infections (2.9% vs. 22.2% respectively, P = 0.013), with no differences in other complications prevalence. After a median follow-up of 46 months, there were similar rates of endoscopic recurrence (47.1% vs. 51.4%, P = 0.72), clinical recurrence (35.3% vs. 47.9%, P = 0.253), and surgical recurrence (2.9% vs. 4.9%, P = 0.722).

Conclusions: Total laparoscopic ileocolic resection with intracorporeal anastomosis for Crohn’s disease is safe and resulted in favorable outcomes in terms of postoperative wound healing. The long-term disease recurrence rates were like those of laparoscopic-assisted and open ileocolic resection.

Background: The prevalence of pregestational diabetes mellitus (PGDM) in women of reproductive age has surged globally, contributing to increased rates of adverse pregnancy outcomes. Hemoglobin A1c (HbA1c) is a crucial marker for diagnosing and monitoring PGDM, with periconceptional levels influencing the risk of congenital anomalies and complications.

Objectives: To evaluate the association between periconceptional HbA1c levels and perinatal complications in pregnant women with poorly controlled PGDM.

Methods: We conducted a retrospective analysis of prospectively collected data of pregnancies between 2010 and 2019, HbA1c > 6% at 3 months prior to conception or during the first trimester. Outcomes of periconceptional HbA1c levels were compared.

Results: The cohort included 89 women: 49 with HbA1c 6–8%, 29 with HbA1c 8–10%, and 11 with HbA1c > 10%. Higher HbA1c levels were more prevalent in type 1 diabetics and were associated with increased end-organ damage risk. Women with elevated HbA1c levels tended toward unbalanced glucose levels during pregnancy. The cohort exhibited high rates of preterm delivery, hypertensive disorders, cesarean delivery, and neonatal intensive care unit admission. Overall live birth rate was 83%. While a significant correlation was found between HbA1c levels and preterm delivery, no consistent association was observed with other adverse outcomes.

Conclusions: Periconceptional glycemic control in PGDM pregnancies is important. Elevated HbA1c levels are associated with increased risks of adverse outcomes. Beyond a certain HbA1c level, risks of complications may not proportionally escalate.

Background: The recreational use of nitrous oxide (N₂O) has increased in recent years with a noticeable surge in the incidence of nitrous oxide-related myeloneuropathy.

Objectives: To raise awareness of increasing myeloneuropathy due to recreational nitrous oxide misuse in Israel.

Methods: We conducted a case series documenting the clinical and investigative features of eight patients presenting with nitrous oxide-induced myeloneuropathy who were admitted to our departments.

Results: Paresthesia was the chief complaint in all patients, with sensory gait ataxia being a common feature, which was often accompanied by Romberg's sign and mild lower limb weakness. Vitamin B12 levels were below the normal range in seven patients, accompanied by elevated homocysteine and methylmalonic acid levels. Magnetic resonance imaging scans revealed hyperintense signals in the dorsal columns of the cervical spine. All patients improved following vitamin B12 injections.

Conclusions: Enhancing awareness, prompting the use of appropriate investigations, and advocating for timely treatment are needed to overcome the risks associated with nitrous oxide misuse.

Background: Pregnant women are at higher risk for severe coronavirus disease 2019 (COVID-19). Since the release of the BNT162b2 messenger RNA vaccine (Pfizer/BioNTech), there has been accumulated data about the three vaccine doses. However, information regarding obstetric and neonatal outcomes of pregnant women vaccinated with the third (booster) vaccine is limited and primarily retrospective.

Objectives: To evaluate the obstetric and early neonatal outcomes of pregnant women vaccinated during pregnancy with the COVID-19 booster vaccine compared to pregnant women vaccinated only by the first two doses.

Methods: We conducted a cross-sectional study of pregnant women who received the BNT162b2 vaccine during pregnancy. Obstetric and neonatal outcomes were compared between pregnant women who received only the first two doses of the vaccine to those who also received the booster dose.

Results: Overall, 139 pregnant women were vaccinated during pregnancy with the first two doses of the vaccine and 84 with the third dose. The third dose group received the vaccine earlier during their pregnancy compared to the two doses group (21² vs. 31⁵ weeks, respectively, P < 0.001). No differences in obstetric and early neonatal outcomes between the groups were found except for lower rates of urgent cesarean delivery in the third dose group (adjusted odds ratio 0.21; 95% confidence interval 0.048–0.926, P = 0.039).

Conclusions: Compared to the first two doses of the BNT162b2 vaccine given in pregnancy, the booster vaccination is safe and not associated with an increased rate of adverse obstetric and early neonatal outcomes.

Background: Presentation of intoxicated patients to hospitals is frequent, varied, and increasing. Medical toxicology expertise could lead to important changes in diagnosis and treatment, especially in patients presenting with altered mental status.

Objectives: To describe and analyze clinical scenarios during a 1-year period after the establishment of a medical toxicology consultation service (MTCS).

Methods: Cases of 10 patients with altered mental status at presentation were evaluated. Medical toxicology consultation suggested major and significant changes in diagnosis and management.

Results: Of 973 toxicology consultations performed during the study period, bedside consultation was provided for 413 (42%) patients. Of these 413, 88 (21%) presented with some level of altered mental status. We described 10 patients in whom medical toxicology consultation brought about major and significant changes in diagnosis and management.

Conclusions: Benefits may be derived from medical toxicology consultations, especially in patients with altered mental status. Medical toxicology specialists are well positioned to provide high value and expedited patient care.

A 42-year-old healthy man collapsed suddenly in the street while walking. The patient received 2 minutes of basic life support until an automatic external defibrillator was brought and detected ventricular fibrillation (VF), which was successfully terminated by a single shock. The patient regained consciousness and was transferred to the hospital.

The patient’s physical examination was normal with no neurologic deficit. Blood pressure was 147/102 mmHg. Brain computed tomography showed normal findings. The first troponin I measurement within 1 hour of the event was in the normal range (19.6 ng/L, normal < 20 ng/L) and rose to 99.9 ng/L after 3 hours.

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.

Infectious endocarditis (IE) remains challenging to treat, with substantial morbidity and mortality rates. Antibiotics are the mainstay of treatment; however, patients with large vegetations often do not respond to antibiotics. Moreover, large vegetations carry an increased risk of embolization. In such cases, guidelines recommend considering surgical treatment [1]. Surgery itself introduces potential complications and high mortality rates [2], and if performed during active infection, the technical possibilities are hindered by a catastrophic recurrence on prosthetic material. Emerging percutaneous solutions to large IE vegetations have been described in recent years to overcome the surgical limitations. Currently, several devices are available. The different debulking mechanisms are based on percutaneous mechanical, either motor or manual aspiration. While becoming more available, percutaneous treatment options are not mentioned in guidelines and data are limited. This report describes a case of percutaneous tricuspid valve (TV) vegetation aspiration using Inari Flowtriever (Inari Medical, Irvine, CA, USA). The case is followed by a review of the literature.

Background: Perianal abscesses require immediate incision and drainage (I&D). However, prompt bedside drainage is controversial as it may compromise exposure and thorough anal examination.

Objectives: To examine outcomes of bedside I&D of perianal abscesses in the emergency department (ED) vs. the operating room (OR).

Methods: We conducted a retrospective review of all patients presented to the ED with a perianal abscesses between January 2018 and March 2020. Patients with Crohn’s disease, horseshoe or recurrent abscesses were excluded.

Results: The study comprised 248 patients; 151 (60.89%) underwent I&D in the OR and 97 (39.11%) in the ED. Patients elected to bedside I&D had smaller abscess sizes (P = 0.01), presented with no fever, and had lower rates of inflammatory markers. The interval time from diagnosis to intervention was significantly shorter among the bedside I&D group 2.13 ± 2.34 hours vs. 10.41 ± 8.48 hours (P < 0.001). Of patients who underwent I&D in the OR, 7.3% had synchronous fistulas, whereas none at bedside had (P = 0.007). At median follow-up of 24 months, recurrence rate of abscess and fistula formation in patients treated in the ED were 11.3% and 6.2%, respectively, vs. 19.9% and 15.23% (P = 0.023, 0.006). Fever (OR 5.71, P = 0.005) and abscess size (OR 1.7, P = 0.026) at initial presentation were risk factors for late fistula formation.

Conclusions: Bedside I&D significantly shortens waiting time and does not increase the rates of long-term complications in patients with small primary perianal abscesses.

Background: Implantable loop recorders (ILRs) are a central tool in the evaluation of unexplained syncope. These devices record and store electrocardiograms, both automatically and on patient-dependent activation. Therefore, obtaining optimal diagnostic results relies on a patient's comprehension and collaboration.

Objectives: To evaluate the effect of ethnic background and mother-tongue language on the diagnostic yield (DY) of ILRs.

Methods: Patients at two medical centers in Israel, who had ILRs as part of syncope workup were included. Inclusion criteria were age over 18 years and an ILR for at least one year (or less if the cause of syncope was detected). Patient demographics, ethnic background, and previous medical history were recorded. All findings from ILR recordings, activation mode (manual vs. automatic), and treatment decisions (none, ablation, device implantation) were collected.

Results: The study comprised 94 patients, 62 Jews (i.e., ethnic majority) and 32 non-Jews (i.e., ethnic minority). While baseline demographic characteristics, medical history, and drug therapy were similar in both groups, Jewish patients were significantly older at the time of device implantation: 64.3 ± 16.0 years of age vs. 50.6 ± 16.9, respectively; (P < 0.001). Arrhythmias recorded in both groups as well as treatment decisions and device activation mode were similar. Total follow-up time from device implantation was longer in the non-Jewish vs. the Jewish group (17.5 ± 12.2 vs. 24.0 ± 12.4 months, respectively; P < 0.017).

Conclusions: The DY of ILR implanted for unexplained syncope did not seem to be influenced by patient's mother-tongue language or ethnicity.

The prevalence of choroidal nevi associated with choroidal neovascular membrane (CNV) is estimated to range between 0.58% and 8.6% [1]. The pathogenesis of CNV is not completely understood. Researchers have suggested that damage caused to the choroid capillaries above the nevi affects the overlying retinal pigment epithelium and triggers production of angiogenic factors that, in turn, cause the development of CNV [2,3]. Hypoxia and inflammation may be involved in the process. Data have been inconsistent with both theories [4].

Background: Acquired hepatocerebral degeneration (AHD) is a neurologic complication of severe chronic liver disease (CLD) with portosystemic shunts. The proposed etiology is manganese accumulation in the brain tissue, especially in the basal ganglia. Combination of clinical manifestation, mostly extrapyramidal movement disorders, and hyperintensities on T1-weighted brain magnetic resonance imaging (MRI) is diagnostic. Although liver transplantation controversial, it is suggested for AHD.

Objectives: To depict clinical and neuroimaging characteristics and response to treatments in patients diagnosed with AHD at Sheba Medical Center.

Methods: Review of patients with AHD diagnosis at the Liver Diseases Center at Sheba Medical Center between 2012 and 2017, data of clinical and neuroimaging, follow-up, and response to treatments, including liver transplantation were recorded.

Results: Five patients with diagnosis of AHD were identified, median age at diagnosis 55 years (range 45–64 years). Four patients had cirrhosis at the time of AHD diagnosis. The main risk factor for AHD was the presence of portosystemic shunts. The most prevalent clinical manifestations were movement disorders, specifically a combination of extrapyramidal and cerebellar signs including instability, rigidity, tremor, bradykinesia, and cognitive impairment. Brain MRI revealed hyperintensities on T1-weighted images in the basal ganglia in all patients. Administration of antiparkinsonian drugs showed clinical improvement, whereas liver transplantation performed in two patients was not associated to neurological improvement.

Conclusions: AHD is related to portosystemic shunts. The combination of Parkinsonism and cerebellar signs and MRI pallidal lesions should alert physicians to the diagnosis. The role of liver transplantation in AHD is still controversial.

Background: The prognosis of long-term clinical outcomes for each patient is of utmost importance.

Objectives: To evaluate the association between rates of family attendance during rounds and long-term outcomes.

Methods: We conducted a historic cohort study.

Results: We followed 200 consecutive patients for a median of 19 months. Within the group of patients that had family members present in > 75% of rounds, the 30-day re-hospitalization rate was tenfold higher (P = 0.017). The overall prognosis (including median survival length) of patients who had the highest rates of family attendance (> 75%) was significantly worse compared to patients who had lower rates (P = 0.028). High rates of family attendance were found to correlate with other established risk factors for long-term mortality, including advanced age (r = 0.231, P = 0.001) and in-hospital delirium.

Conclusions: High family attendance during physician rounds in an internal medicine department is associated with worse patient prognosis.

Coronavirus disease 2019 (COVID-19) affects different people in different ways. Most infected people develop mild to moderate illness and recover without hospitalization. This case report presents a patient who had difficulty eradicating the corona virus due to being treated with rituximab, which depletes B lymphocytes and therefore disables the production of neutralizing antibodies. The regen-COV-2 antibody cocktail consists of two monoclonal antibodies, casirivimab and imdevimab. This cocktail successfully helped the patient's immune system eradicate the virus without auto specific severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody production. In vitro studies confirm that eradication of the intact the virus. This case report emphases the importance of providing external antiviral antibodies regularly, like the regen-COV-2 antibody cocktail, as post- and even pre- SARS-CoV-2 infection prophylaxis in patients treated with rituximab.

Background: Most dyspneic patients in internal medicine departments have co-morbidities that interfere with the clinical diagnosis. The role of brain natriuretic peptide (BNP) levels is well-established in the acute setting but not in hospitalized patients.

Objectives: To evaluate the additive value of BNP tests in patients with dyspnea admitted to medical wards who did not respond to initial treatment.

Methods: We searched the records of patients who were hospitalized in the department of internal medicine D at Sheba Medical Center during 2012 and were tested for BNP in the ward. Data collected included co-morbidity, medical treatments, diagnosis at presentation and discharge, lab results including BNP, re-hospitalization, and mortality at one year following hospitalization.

Results: BNP results were found for 169 patients. BNP was taken 1.7 ± 2.7 days after hospitalization. According to BNP levels, dividing the patients into tertiles revealed three equally distributed groups with a distinctive character. The higher tertile was associated with higher rates of cardiac co-morbidities, including heart failure, but not chronic obstructive pulmonary disease. Higher BNP levels were related to one-year re-hospitalization and mortality. In addition, higher BNP levels were associated with higher rates of in-admission diagnosis change.

Conclusions: BNP levels during hospitalization in internal medicine wards are significantly related to cardiac illness, the existence of heart failure, and patient prognosis. Thus, BNP can be a useful tool in managing dyspneic patients in this setting.
