Background: Isolated peripheral artery aneurysms are very rare, appearing in fewer than 2% of the general population. The literature reports a few case reports of poliomyelitis patients presenting with unilateral leg paralysis that presented with peripheral aneurysms in the contralateral leg.

Objectives: To compare lower limb arterial diameters in poliomyelitis patients and screen these patients for peripheral aneurysms.

Methods: Poliomyelitis patients older than 55 years of age with unilateral leg paralysis since childhood were prospectively screened by ultrasound duplex during scheduled visits to the outpatient rehabilitation center. These results were compared to the control group. The control groups consisted of healthy adults and patients with childhood poliomyelitis without lower limb paralysis or symmetric bilateral limb paralysis. We measured the diameter of nine arteries in each participant (aorta, bilateral common iliac artery, bilateral common femoral artery, bilateral superficial femoral artery, and bilateral popliteal artery).

Results: The study cohort included 77 participants: 40 poliomyelitis patients with unilateral leg paralysis, 18 poliomyelitis patients with bilateral leg paralysis or without leg paralysis, and 19 non-poliomyelitis patients without leg paralysis. We demonstrated a significant difference between averaged arterial diameters of lower limb arteries in poliomyelitis patients, favoring the strong leg. We were unable to demonstrate an arterial aneurysm in any of the patients.

Conclusions: There is a significant difference between arterial diameters of lower limb arteries in poliomyelitis patients with unilateral leg paralysis in favoring the strong leg.

Background: Patients with mechanical prosthetic heart valves must be treated with vitamin K antagonists (VKA) due to an increased risk of valve thrombosis and systemic embolism.

Objectives: To assess the effects of the COVID-19 pandemic on VKA treatment control in patients with mechanical prosthetic heart valves.

Methods: We conducted a retrospective nationwide cohort study using the Clalit Health Services database. The cohort included patients who underwent either aortic or mitral valve replacement using a prosthetic mechanical valve. The primary outcomes included the overall time in therapeutic range (TTR) and the percent of patients with a TTR < 50% during the first year of the COVID-19 pandemic compared to preceding year.

Results: The cohort included 2381 patients. The percentage of patients who had at least two international normalized ratio (INR) tests during the first year of the COVID-19 pandemic was significantly lower compared to the year preceding the pandemic (81% and 87%, respectively, P < 0.001). In both years, the percentage of patients without any documented INR test was high (31.5% in the first COVID-19 pandemic year and 28.9% in the preceding year, P < 0.001). TTR was significantly lower during the 1st year of the COVID-19 pandemic compared to the preceding year (68.1% ± 26 and 69.4% ± 24, P = 0.03). A TTR > 50% was demonstrated in 78% and 81% during the pandemic and the preceding year, P = 0.009.

Conclusions: We noted overall poor VKA control in patients with mechanical heart valves. During the COVID-19 pandemic, VKA control became even worse as reflected by significantly lower TTR and INR tests rates.

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.

Background: The coronavirus disease 2019 (COVID-19) pandemic caused significant global turmoil, including changes in social and societal conduct such as lockdowns, social isolation, and extensive regulations. These changes can be major sources of stress. The first wave of the pandemic (April–May 2020) was a time of global uncertainty. We evaluated symptom severity among 29 Israeli children and adolescents with obsessive-compulsive disorder (OCD). Our previous study found that most of these participants did not experience an exacerbation of symptoms.

Objective: To re-evaluate the OCD symptoms of 18 participants from the original group of 29 children and adolescents during three time points: before the pandemic, during the first wave, and 2 years later.

Methods: Obsessive-compulsive symptoms (OCS) were assessed using the Clinical Global Impression Scale (CGI), a functional questionnaire, and the Obsessive-Compulsive Inventory-child version (OCI-CV).

Results: OCS in patients did not change significantly during the three time points. Participants reported minimal changes in their general functioning 2 years after the outbreak of COVID-19 and showed minimal change in OCI-CV scale scores.

Conclusions: Our results indicated clinical stability of OCD symptoms among most of the participants.

Background: At the beginning of 2020, the coronavirus disease 2019 (COVID-19) pandemic presented a new burden on healthcare systems.

Objectives: To evaluate the impact of the COVID-19 pandemic on the outcome of non-COVID patients in Israel.

Methods: We conducted a retrospective observational cohort study at a tertiary medical center in Israel. From December 2018 until June 2022, 6796 patients were hospitalized in the internal medicine wards. Patients were grouped based on their admission date: admitted during COVID waves (waves group), admitted between waves (interim group), and admitted during the same months in the previous year (former-year group).

Results: Mortality during hospitalization and 30-day mortality were higher in the waves group compared to the interim and former-year groups (41.4% vs. 30.5% and 24%, 19.4% vs. 17.9% and 12.9%, P < 0.001). In addition, 1-year mortality was higher in the interim group than in the waves and former-year group (39.1 % vs. 32.5% and 33.4%, P = 0.002). There were significant differences in the readmissions, both at 1 year and total number. The waves group had higher rates of mechanical ventilation and noradrenaline administration during hospitalization. Moreover, the waves group exhibited higher troponin levels, lower hemoglobin levels, and more abnormalities in liver and kidney function.

Conclusions: Hospitalized non-COVID patients experienced worse outcomes during the peaks of the pandemic compared to the nadirs and the preceding year, perhaps due to the limited availability of resources. These results underscore the importance of preparing for large-scale threats and implementing effective resource allocation policies.

Background: Computed tomography (CT) is the main diagnostic modality for detecting pancreatic adenocarcinoma.

Objectives: To assess the frequency of missed pancreatic adenocarcinoma on CT scans according to different CT protocols.

Methods: The medical records of consecutive pancreatic adenocarcinoma patients were retrospectively collected (12/2011–12/2015). Patients with abdominal CT scans performed up to a year prior to cancer diagnosis were included. Two radiologists registered the presence of radiological signs of missed cancers. The frequency of missed cancers was compared between portal and pancreatic/triphasic CT protocols.

Results: Overall, 180 CT scans of pancreatic adenocarcinoma patients performed prior to cancer diagnosis were retrieved; 126/180 (70.0%) were conducted using pancreatic/triphasic protocols and 54/180 (30.0%) used portal protocols. The overall frequency of missed cancers was 6/180 (3.3%) in our study population. The frequency of missed cancers was higher with the portal CT protocols compared to the pancreatic/triphasic protocols: 5/54 (9.3%) vs. 1/126 (0.8%), P = 0.01. CT signs of missed cancers included small hypodense lesions, peri-pancreatic fat stranding, and dilated pancreatic duct with a cut-off sign.

Conclusions: The frequency of missed pancreatic adenocarcinoma is higher on portal CT protocols. Physicians should consider the cancer miss rate on different CT protocols.

Background: Perivascular cuffing as the sole imaging manifestation of pancreatic ductal adenocarcinoma (PDAC) is an under-recognized entity.

Objectives: To present this rare finding and differentiate it from retroperitoneal fibrosis and vasculitis.

Methods: Patients with abdominal vasculature cuffing were retrospectively collected (January 2011 to September 2017). We evaluated vessels involved, wall thickness, length of involvement and extra-vascular manifestations.

Results: Fourteen patients with perivascular cuffing were retrieved: three with celiac and superior mesenteric artery (SMA) perivascular cuffing as the only manifestation of surgically proven PDAC, seven with abdominal vasculitis, and four with retroperitoneal fibrosis. PDAC patients exhibited perivascular cuffing of either or both celiac and SMA (3/3). Vasculitis patients showed aortitis with or without iliac or SMA cuffing (3/7) or cuffing of either or both celiac and SMA (4/7). Retroperitoneal fibrosis involved the aorta (4/4), common iliac (4/4), and renal arteries (2/4). Hydronephrosis was present in 3/4 of retroperitoneal fibrosis patients. PDAC and vasculitis demonstrated reduced wall thickness in comparison to retroperitoneal fibrosis (PDAC: 1.0 ± 0.2 cm, vasculitis: 1.2 ± 0.5 cm, retroperitoneal fibrosis: 2.4 ± 0.4 cm; P = 0.002). There was no significant difference in length of vascular involvement (PDAC: 6.3 ± 2.1 cm, vasculitis: 7.1 ± 2.6 cm, retroperitoneal fibrosis: 8.7 ± 0.5 cm).

Conclusions: Celiac and SMA perivascular cuffing can be the sole finding in PDAC and may be indistinguishable from vasculitis. This entity may differ from retroperitoneal fibrosis as it spares the aorta, iliac, and renal arteries and demonstrates thinner walls and no hydronephrosis.

Pancreaticopleural fistula (PPF) is a rare complication of pancreatitis and usually constitutes a diagnostic challenge. There are many causes for recurrent and chronic pancreatitis, with the main etiology being alcohol and choledocholithiasis [1]. However, the association between pancreatic divisum (PD), a common congenital anomaly of the pancreas that is rarely symptomatic, and complications of pancreatitis is still not firmly established [2]. Furthermore, the optimal management of PPF is still uncertain due to its rarity [3]. We describe a rare case of a 45-year-old woman with recurrent pancreatitis that presented with a PPF on the background of PD, successfully managed with conservative treatment. The purpose of this report is to highlight the rare association between PPF and PD together with the excellent response to conservative therapy.

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: In late 2019, a new strain of coronavirus (coronavirus disease 2019 [COVID-19]) spread rapidly throughout the world. The American Society of Plastic Surgeons reported a pandemic-related surge in the demand for aesthetic surgery compared to the same popularity of procedures prior to the pandemic.

Objectives: To determine whether this phenomenon also occurred in Israel.

Methods: We collected data from three leading private medical centers in Tel Aviv. Data were compared for the years 2019 and 2020 by surgical procedure. Number of orthopedic, gynecologic, and hand procedures served as control data.

Results: We present a detailed pandemic-related timeline relevant to aesthetic surgery in Israel. Overall, the demand for aesthetic surgery increased, with a marked trend toward body contouring procedures.

Conclusions: The Israeli aesthetic surgery market was affected by the COVID-19 pandemic, with a post-closure surge. The popularity and number of procedures are unique to the Israeli market.

Background: Chronic suppurative otitis media is a long-standing middle ear infection with a perforated tympanic membrane. Tympanoplasty is the mainstay of treatment. Most surgeons prefer to operate on dry ears; however, this may be difficult to achieve.

Objectives: To investigate the effect of otorrhea and positive cultures on the outcome of tympanoplasty.

Methods: This retrospective analysis reviewed patients with chronic suppurative otitis media who underwent tympanoplasty 2008–2015. Patients were divided into three groups: active discharge and bacterial growth, active discharge without bacterial growth, and no ear discharge. Surgical outcomes were compared among the groups.

Results: Among 101 patients included, 43 ears (42.6%) had discharge preoperatively, 58 (57.4%) were dry. Overall closure rate was 81.2% (82/101). Preoperative active discharge closure rate was 88.3% (38/43) and without discharge 75.9% (44/58). There were 38 positive cultures preoperatively and five negative cultures. Cultures were not obtained in 58 cases. Success rates were 89.5%, 80%, and 75.9%, respectively. No significant difference was found between patients who had positive or negative cultures before the procedure (P > 0.48) or among the three groups (P = 0.25). The most common bacteria were Pseudomonas aeruginosa (n=17), followed by Staphylococcus species (n=10). None was significantly associated with operative failure (P = 0.557). The postoperative air threshold difference was not affected by culture results (P = 0.3).

Conclusions: Tympanoplasty success rates and postoperative air threshold differences were not affected by the presence of preoperative otorrhea or positive ear cultures. Surgery can be performed even when the ear is not dry.

Background: Gestational hypertensive (GH) disorders remain a major obstetric problem.

Objective: To evaluate the incidence of gestational hypertensive disorders among participants undergoing intrauterine insemination (IUI) after exposure to various levels of sperm from sperm donation (SD).

Methods: A retrospective case-control study was conducted at a single tertiary medical center between 2011 and 2019. Participants conceived via IUI using SD from a single sperm bank and had a successful singleton birth. Group 1 conceived during 1–2 cycles of IUI from the same sperm donor; whereas Group 2 after 3+ cycles.

Results: Overall 171 patients (Group 1 = 81, Group 2 = 90) met inclusion criteria. Participants showed no differences in age, chronic medical conditions, or history of pregnancy complications. The groups differed in gravidity and parity. The factors positively associated with Group 1 included either preeclampsia or GH (11 [13.5%] vs. 1 [1.1%], P = 0.001) and GH alone (8 [9.9%] vs. 1 [1.1%], P = 0.014). Newborns from Group 1 had a statistically significant lower birth weight than those from Group 2 (3003 grams ± 564.21 vs. 3173 grams ± 502.59, P = 0.039). GH was more prevalent in Group 1 (P = 0.008) than a control group of 45,278 participants who conceived spontaneously. No significant differences were observed between Group 2 and the control group.

Conclusions: The incidence of GH and preeclampsia in participants was higher among those exposed to 1–2 cycles than those exposed to 3+ cycles of IUI.

Background: To mitigate the spread of coronavirus disease 2019 (COVID-19), national guidelines, in accordance with international health authorities, mandated 14 days of quarantine for every close contact of a confirmed COVID-19 patient. Although health benefits are obvious, consequences are profound, especially for organizations required to maintain operational preparedness.

Objectives: To present the Israel Defense Force (IDF) experience with outbreaks regarding quarantined individuals. To weigh the consequences of quarantined individuals needed for workforce and operation.

Methods: All positive COVID-19 cases in the IDF, as measured by a positive rRT-PCR test result, between 29 February and 18 May 2020 were evaluated. Numbers of positive individuals, quarantined individuals, and confirmatory exams conducted were collected. We compared the events in four units with the largest outbreaks and assessed the impact of confirmed cases, tests conducted, and workforce loss due to quarantine.

Results: Of the 187 soldiers who tested positive for COVID-19, source of infection was traced to 140 soldiers (75%). Almost no medical treatment was delivered, and hospitalization was rare. We found a median of 15.2% (interquartile range 5.3–34) for decline in unit workforce due to quarantine measures. Maximum reduction reached 47% of the workforce in one unit.

Conclusions: Despite a relatively small number of confirmed cases, units underwent a substantial change in mode of operation due to the toll of quarantined individuals. In certain populations and organizations, perhaps a more liberal application of isolation and contact tracing is suitable due to the heavy economic burden and consequences in term of operational readiness.

Background: Data on how the coronavirus disease 2019 (COVID-19) affected consultations in ophthalmic departments are sparse.

Objectives: To examine the epidemiology of ophthalmic consultations in a large pediatric emergency medicine department (PED) during the first nationwide COVID-19 lockdown in Israel.

Methods: The database of a tertiary pediatric medical center was retrospectively reviewed for patients aged < 18 years who attended the PED from 17 March to 30 April 2020 (first COVID-19 lockdown) and the corresponding period in 2019. Background, clinical, and disease-related data were collected from the medical charts and compared between groups.

Results: The study included 757 PED visits. There were no significant differences in demographics between the groups. The 2020 period was characterized by a decrease in PED visits (by 52%), increase in arrivals during late afternoon and evening (P = 0.013), decrease in visits of older children (age 5–10 year), and proportional increase in younger children (age 1–5 years) (P = 0.011). The most common diagnoses overall and during each period was trauma followed by conjunctivitis and eyelid inflammation. The mechanisms of trauma differed (P = 0.002), with an increase in sharp trauma and decrease in blunt trauma in 2020 (P < 0.001 for both). In 2020, 95% of traumatic events occurred in the home compared to 54% in 2019 (P < 0.001).

Conclusions: Parents need to learn appropriate preventive and treatment measures to prevent serious and long-term ophthalmic injury while minimizing their exposure to the COVID-19. PEDs and ophthalmic pediatric clinics should consider increasing use of telemedicine and the availability of more senior physicians as consultants during such times.

Background: The influence of the coronavirus disease 2019 (COVID-19) pandemic caused countries worldwide to implement lockdowns. Elective surgeries were temporarily suspended, with surgeries being performed only for emergent/urgent medical conditions such as hip fractures where early surgical intervention has shown decreased rates of morbidity/mortality.

Objectives: To assess the indirect influence of the COVID-19 pandemic and associated lockdown on hip fracture patients, considering factors such as time to surgery, early postoperative complications, and ambulation status.

Methods: A comparative retrospective study was conducted on consecutive patients presenting to our emergency department (ED) with hip fractures that were treated surgically (N=29) during a 1-month period during the government lockdown due to the COVID-19 pandemic. The treatments were compared to consecutive patients who presented with hip fractures and were treated surgically (N=44) during the same timeframe in the previous year (control). Comparisons were made using t-test, ANOVA test, Fisher's exact test, and chi-square test.

Results: The COVID-19 group was operated on sooner (20.34 vs. 34.87 hours), had fewer early postoperative complications (10.3% vs. 31.8%), had better ambulatory status at discharge, and experienced a shorter hospital stay (5.93 vs. 8.13 days) with more patients being discharged home (72.4% vs. 22.7%).

Conclusions: Patients presenting with hip fractures to our ED during the COVID-19 pandemic lockdown indirectly benefited from this situation by undergoing earlier surgical treatment, thus experiencing fewer early postoperative complications, faster ambulation, and sooner discharge.
