Background: Cloacal malformation represents the rarest and most complex congenital anorectal malformation in females and is characterized by the convergence of urinary, gynecological, and intestinal systems within a single common channel. Three-dimensional computed tomography reconstruction (3D CT cloacagram) has emerged as a valuable method for anatomical assessment and preoperative planning.

Objectives: To evaluate our experience with 3D CT cloacagram and assess its results.

Methods: This retrospective case series included all patients with cloacal malformation who underwent preoperative 3D CT cloacagram at a single institution during 2019–2023. Collected data included patient characteristics, timing of the 3D CT cloacagram, results of the 3D CT cloacagram, comparison with endoscopic results, surgical procedures, and postoperative outcome.

Results: Six patients with cloacal malformation were included in this study, including two with posterior cloaca. The median common channel length on 3D CT cloacagram was 24.5 mm (range 9–48 mm) and the median urethral length was 15.5 mm (range 13-24 mm). The surgical approach involved a combined abdominoperineal approach in three patients and posterior sagittal anorectal vaginal urethral plasty in one patient. Two patients were awaiting surgical reconstruction at the time of publication.

Conclusions: Our implementation of 3D cloacagram has facilitated precise measurements of both the urethra and common channel lengths, two key factors in formulating surgical strategies for cloacal reconstruction. Moreover, this technique has markedly improved our capacity for surgical planning contributing to colorectal, gynecological, and urological perspectives.

Kidney involvement in systemic sclerosis (SSc) is common with altered kidney function present in approximately half of the patients [1]. Scleroderma renal crisis (SRC), the most severe kidney manifestation, occurs in about 20% of patients with this autoimmune disorder [1]. SRC mainly affects patients with the diffuse cutaneous systemic sclerosis (dcSSc) subtype of the disease, and particularly in those who are seropositive to anti RNA polymerase III antibodies [2]. In recent years, the prevalence of SRC has decreased following the initiation of medication therapy with angiotensin-converting-enzyme inhibitors (ACE-i). Previously, SRC mortality rates were as high as 78%. Contemporary studies in the post-ACE-i era suggest lower rates, with mortality rate ranging from 30% to 36% [3]. Nevertheless, progression to end-stage renal disease (ESRD) is evident and may require renal replacement therapies (RRTs). While renal transplant rates in SSc have increased, they constitute a small proportion of SSc-SRC patients (3–8%) and SSc-ESRD patients (4–17%).

War is a chaotic situation for most of the public sectors in the countries involved. These sectors also include the medical systems, especially medical education, of which medical communication is often neglected or forgotten due to objective and subjective causes on either side of the involved countries. By planning lessons on various aspects of medicine for countries at war and close mentoring and utilization of modern communications technologies, these difficulties can be minimized without jeopardizing the quality of medical studies nor medical communication. In this perspective article, we describe the objective and subjective measures taken by our team to achieve these goals during the Iron Swords war in our region.

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.

Idiopathic eosinophilic vasculitis is a newly recognized form of hypereosinophilic syndrome. While little is understood about the condition, criteria for its definition have been proposed. We aimed to determine whether three patients with eosinophilia and vasculitis could be retrospectively diagnosed with this condition. We performed a retrospective descriptive analysis on three cases with hypereosinophilia and vasculitis who were treated in Sheba Medical Center, Sourasky Medical Center, and Meir Medical Center in Israel between 2009 and 2021. A thorough review of all three cases was conducted. The findings were compared to the suggested criteria for idiopathic eosinophilic vasculitis.

All patients shared the symptoms of progressive limb ischemia, eosinophilic rash, and peripheral neuropathy that are consistent with vasculitis. No lower or upper respiratory abnormalities or the presence of anti-neutrophil cytoplasmic antibodies (ANCA) autoantibodies associated with eosinophilic granulomatosis with polyangiitis were detected. Primary monoclonal abnormalities, drug interactions, infections, allergy, and other secondary causes of hypereosinophilia were excluded. After a thorough review, we suggest that our three patients with previously unexplained hypereosinophilia and vasculitis fit the diagnosis of idiopathic eosinophilic vasculitis. These results highlight the existence of this novel condition and the importance of its recognition and consideration as part of the differential diagnosis in patients with marked eosinophilia and vasculitis. Further research for elucidating the mechanisms and treatment approach for this potentially severe condition is urgently needed.

Background: Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics.

Objectives: To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora.

Methods: We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology.

Results: Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855).

Conclusions: Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.

Takotsubo syndrome (TTS) or Takotsubo cardiomyopathy (TCM) is a cardiomyopathy that develops rapidly and is usually caused by mental or physical stress. It is usually a transient cardiomyopathy. The presumed cause of the onset of the syndrome is the increase and extreme secretion of adrenaline and norepinephrine due to extreme stress. An infectious disease such as sepsis can also be the cause [1].

One of the most widespread diagnostic tools is the revised version of Mayo Clinic Diagnostic Criteria for TTS (2008) [2], which incorporates transient wall-motion abnormalities, absence of a potential coronary culprit, myocarditis, and pheochromocytoma. The prognosis for TTS is usually favorable and resolves with complete recovery in 4–8 weeks in more than 90% of patients.

Background: The Gaza–Israeli conflict poses challenges for unbiased reporting due to its complexity and media bias. We explored recent scientific publications to understand scholarly discourse and potential biases surrounding this longstanding geopolitical issue.

Objectives: To conduct a descriptive bibliometric analysis of PubMed articles regarding the recent Gaza–Israeli conflict.

Methods: We reviewed 1628 publications using keywords and medical subject headings (MeSH) terms related to Gaza, Hamas, and Israel. We focused on articles written in English. A team of researchers assessed inclusion criteria, resolving disagreements through a third researcher.

Results: Among 37 publications, Lancet, BMJ, and Nature were prominent journals. Authors from 12 countries contributed, with variety of publication types (46% correspondence, 32% news). Pro-Gaza perspectives dominated (43.2%), surpassing pro-Israel (21.6%) and neutral (35.1%) viewpoints. Pro-Gaza articles exhibited higher Altmetric scores, indicating increased social media impact. Pro-Israel publications were predominantly authored by Israelis.

Conclusions: The prevalence of pro-Gaza perspectives underscores challenges in maintaining impartiality. Higher social media impact for pro-Gaza publications emphasizes the need for nuanced examination. Addressing bias is crucial for a comprehensive understanding of this complex conflict and promoting balanced reporting.

Background: Unfractionated heparin is the preferred anticoagulant used during open heart surgeries, including left ventricular assist device (LVAD) implantation. In cases in which patients are heparin-induced thrombocytopenia positive (HIT+), the accepted practice has been to substitute heparin with bivalirudin. This practice may be associated with significant bleeding and adverse outcomes.

Objectives: To review our experience with HIT+ patients who were heparin-induced thrombocytopenia with thrombosis negative (HITT-) and who underwent HeartMate 3 LVAD implantation using heparin intraoperatively rather than bivalirudin.

Methods: From 2016 to 2022, 144 adult patients were implanted with HeartMate 3 LVAD at our center. Among them, 7 were detected as HIT+ but HITT- and therefore were prescribed intraoperatively with heparin and treated pre- and postoperatively with bivalirudin. We reviewed the preoperative, intraoperative, and postoperative characteristics as well as short-term mortality and the complication rates of these HIT+ patients.

Results: The median age of our cohort was 56 years (51–60), 71% were male (n=5), all were INTERMACS Level 1, and most were bridged to transplant (n=6, 86%). The 30-day mortality rate post-implantation was 0%. The average 24-hour chest drain postoperative output was 1502.86 ± 931.34 ml. There were no intraoperative pump thromboses, perioperative thromboses, cerebrovascular accidents, or gastrointestinal bleeding within the first 24 hours postoperative. One patient required a revision due to bleeding.

Conclusions: Intraoperative unfractionated heparin may be administered to patients who are HIT+ and HITT- while undergoing LVAD implantation. However, further investigation is required.

Background: While several studies have noted smell impairment in schizophrenia, it is unclear whether this impairment extends to acute psychosis and whether it is associated with more severe illness as expressed in extended hospitalization.

Objectives: To evaluate the olfactory function of patients in an acute psychotic state and correlate it with clinical symptomatology and length of hospitalization.

Methods: Olfactory function was assessed in 20 patients with schizophrenia in their first week of hospital admission for acute psychosis compared with matched controls. Olfaction was evaluated via three stages: threshold, discrimination, and identification of different odors utilizing the Sniffin' Sticks test battery.

Results: Schizophrenia patients scored significantly lower on total smell score, discrimination, and identification abilities. A significant association was observed between hospitalization duration and total smell score and smell discrimination. No significant associations between smell and clinical symptomatology were observed.

Conclusions: Study observations confirm impaired sense of smell in schizophrenia patients and suggest that smell impairment may be a potential marker of more serious illness as expressed in longer hospital stay.

Background: During coronavirus disease 2019 (COVID-19) pandemic, less isolation of common winter viruses was reported in the southern hemisphere.

Objectives: To evaluate annual trends in respiratory disease-related admissions in a large Israeli hospital during and before the pandemic.

Methods: A retrospective analysis of medical records from November 2020 to January 2021 (winter season) was conducted and compared to the same period in two previous years. Data included number of admissions, epidemiological and clinical presentation, and isolation of respiratory pathogens.

Results: There were 1488 respiratory hospitalizations (58% males): 632 in 2018–2019, 701 in 2019–2020, and 155 in 2020–2021. Daily admissions decreased significantly from a median value of 6 (interquartile range [IQR] 4–9) and 7 per day (IQR 6–10) for 2018–2019 and 2019–2020, respectively, to only 1 per day (IQR 1–3) in 2020–2021 (P-value < 0.001). The incidence of all respiratory viruses decreased significantly during the COVID-19 pandemic, with no hospitalizations due to influenza and only one with respiratory syncytial virus. There was also a significant decline in respiratory viral and bacterial co-infections during the pandemic (P-value < 0.001).

Conclusions: There was a significant decline in pediatric respiratory admission rates during the COVID-19 pandemic. Possible etiologies include epidemiological factors such as mask wearing and social distancing, in addition to biological factors such as viral interference. A herd protection effect of adults and older children wearing masks may also have had an impact.

Background: Anal squamous cell carcinoma (ASqCC) is a rare malignancy, traditionally treated with combined chemoradiation, with a continuous infusion of 5-fluorouracil (5-FU) and mitomycin C (MMC). Replacing intravenous (IV) 5-FU with oral capecitabine (oral fluoropyrimidine) has been reported as a non-inferior treatment option. However, these data are scarce, with variable results.

Objectives: To examine the outcome of patients with ASqCC treated with either IV 5-FU or capecitabine concomitantly with radiation therapy. To compare treatment side effects, local recurrence, and general outcome.

Methods: We reviewed charts of patients who were diagnosed with stage I–III ASqCC. All participating patients received chemoradiation at the Assuta Medical Center between 2011 and 2019.

Results: In this study, 43 patients with ASqCC were eligible; 14 received 5-FU and 29 were treated with capecitabine. Basic characteristics were similar between the two groups, with longer follow-up for the 5-FU group. Six months following treatment, 100% (13/13 with adequate follow-up) of the 5-FU group had complete clinical response, compared to 84% in the capecitabine group (21/24), P = 0.143. The local recurrence incidence was higher in the 5-FU group at 23% (7, 10, 26 months following therapy, and none in the capecitabine group (P = 0.088). Although local and hematological toxicities were similar between groups, one patient receiving capecitabine died during chemoradiotherapy.

Conclusions: Oral capecitabine demonstrated non-inferior disease control in ASqCC treated with chemoradiotherapy. We recommend oral capecitabine over continuous IV 5-FU in locally and locally advanced ASqCC. Close monitoring of side effects is required to reduce major toxicity.

Takotsubo syndrome (TTS) often develops following stressors such as cardiac surgery. It may be fatal in rare cases. Our 70-year-old female patient presented with a rare case of tricuspid valve papillary fibroelastoma, which was complicated by fatal TTS after successful resection. The patient had a right atrial mass that was investigated with computed tomography and transesophageal echocardiography (TTE). She was scheduled for surgery. Pathology findings were consistent with papillary fibroelastoma of the tricuspid valve. Three weeks after successful surgery, the patient was admitted due to cardiogenic shock with echocardiographic findings of apical ballooning and left ventricular outflow tract obstruction consistent with TTS. The patient died one hour after her admission despite optimal medical therapy.

Background: Polyp detection rate (PDR) is a convenient quality measure indicator. Many factors influence PDR, including the patient's background, age, referral (ambulatory or hospitalized), and bowel cleansing.

Objectives: To evaluate whether years of professional experience have any effect on PDR.

Methods: A multivariate analysis of a retrospective cohort was performed, where both patient- and examiner-related variables, including the experience of doctors and nurses, were evaluated. PDR, as the dependent variable was calculated separately for all (APDR), proximal (PPDR), and small (SPDR) polyps.

Results: Between 1998 and 2019, 20,996 patients underwent colonoscopy at a single center. After controlling for covariates, the experience of both doctors and nurses was not found to be associated with APDR (odds ratio [OR] 0.99, 95% confidence interval [95%CI] 0.98–1.00, P = 0.15 and OR 1.03, 95%CI 1.02–1.04, P < 0.0001, respectively). However, after 2.4 years of colonoscopy experience for doctors, and 9.5 years of experience for nurses, a significant increase in APDR was observed. Furthermore, results revealed no association for PPDR and SPDR, as well.

Conclusions: Years of colonoscopy experience for both doctors and assisting nurses were not associated with APDR, PPDR, and SPDR. In doctors with 2.4 years of experience and nurses with 9.5 years of experience, a significant increase in APDR was observed.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in more than four million deaths globally. In addition to the lower respiratory system, a wide range of major organ injuries have been reported among patients infected with COVID-19. These injuries include cardiac involvement. The spectrum of cardiac manifestations includes cardiac injury, heart failure, cardiogenic shock, acute coronary syndrome, myocarditis, tachyarrhythmias, and bradyarrhythmia [1]. Different degrees of atrioventricular blocks have been reported [2].

The pathogenesis of these complications is not fully understood. Differentmechanisms are proposed, including direct myocyte injury, interstitial inflammation and fibrosis, cytokine storm, plaque destabilization, and and/or hypoxia [3]. Many countries have worked toward mass vaccination using the Pfizer BioNTech (BNT162b2) COVID-19 vaccine, including Israel. We report a case of high degree atrioventricular block (AVB) following vaccination with the COVID-19 BNT162b2 vaccine.
