Background: Radical cystectomy is a complicated surgery with significant risks. Complications of Clavien–Dindo grade 3–4 range from 25% to 40% while risk of mortality is 2%. Pelvic surgery or radiotherapy prior to radical cystectomy increases the challenges of this surgery.

Objectives: To assess whether radical cystectomy performed in patients with prior history of pelvic surgery or radiation was associated with increased frequency of Clavien–Dindo grade 3 or higher complications compared to patients without prior pelvic intervention.

Methods: We retrospectively evaluated all patients who underwent radical cystectomy at our center over a 7-year period. All patients with pelvic radiation or surgery prior to radical cystectomy comprised group 1, while group 2 included the remaining patients.

Results: In our study, 65 patients required radical cystectomy at our institution during the study period. Group 1 was comprised of 17 patients and group 2 included 48 patients. Four patients from group 2 received orthotopic neobladder, while an ileal conduit procedure was performed in the remaining patients. Estimated blood loss and the amount of blood transfusions given was the only variable found to be statistically different between the two groups. One patient from group 1 had four pelvic interventions prior to surgery, and her cystectomy was aborted.

Conclusions: Radical cystectomy may be safely performed in patients with a history of pelvic radiotherapy or surgery, with complication rates similar to those of non-irradiated or operated pelvises.

Background: Little is known regarding the impact of the coronavirus disease-2019 (COVID-19) pandemic on the incidence of hip fractures among older adults

Objectives: To compare the characteristics of patients with a hip fracture following a fall during the COVID-19 pandemic year and during the preceding year.

Methods: We conducted a retrospective cohort study of older patients who had undergone surgery for hip fracture repair in a major 495-bed hospital located in northern central Israel following a fall. Characteristics of patients who had been hospitalized in 2020 (pandemic year, n=136) and in 2019 (non-pandemic year, n=151) were compared.

Results: During the pandemic year, patients were less likely to have fallen in a nursing facility, to have had muscle or balance problems, and to have had a history of falls and fractures following a fall. Moreover, the average length of stay (LOS) in the hospital was shorter; however, the average time from the injury to hospitalization was longer. Patients were less likely to have acquired a postoperative infection or to have died. During the pandemic year, postoperative infection was only associated with prolonged LOS.

Conclusions: The COVID-19 pandemic may have had a positive impact on the behavior of older adults as well as on the management of hip fracture patients. However, healthcare providers should be aware of the possible reluctance to seek care during a pandemic. Moreover, further research on the impact of the change in management during COVID-19 on hip fracture survival is warranted

Background: In recent years, treatment for Achilles tendon rupture (ATR) went through radical changes: from the conservative non-weight bearing approach to a functional protocol. This functional protocol allows complete weight bearing after only 2 weeks by placing the foot in a plastic boot in tapered down equines and using interchangeable wedges under the heel. This change of approach has dramatically lowered the rate of re-rupture.

Objectives: To describe our preliminary results with this functional protocol and to assess outcome measures in the functional conservative treatment.

Methods: The study comprised 15 people who were evaluated clinically and by sonograph. We measured calf circumference, ankle joint range of motion (ROM), and single-leg heel-rise test (SLHRT). In addition, standard scoring methods (Achilles Tendon Rupture Score and Physical Activity Scale) were examined.

Results: In our cohort 14 people successfully gained SLHRT. The mean Achilles Tendon Rupture Score functional questionnaire and Physical Activity Scale physical activity questionnaire score was 85.6 of 100, and 4.7 of 6, respectively. There were no significant differences in ankle ROM compared to the uninjured limb. There was statistically significant reduction in the calf circumference and soleus muscle thickness sonographically.

Conclusions: It seems that the conservative functional treatment of ATR demonstrates good functional outcomes, with the patients returning to close to normal activity, although noted muscle wasting and weakness. This protocol presents a true alternative to surgery and should be considered for most non-insertional Achilles tendon tears

Background: With diagnostic imaging, such as a duplex of the carotid arteries, finding of stenosis and atherosclerotic plaque and consequent end arterectomy may be important for decreasing the danger of developing cerebrovascular accident after transient ischemic attack (TIA).

Objectives: To measure performance rates of duplex of carotid arteries within 72 hours of TIA diagnosis.

Methods: The denominator included all patients who were admitted to emergency departments because of TIA, and the numerator included those who underwent duplex within 72 hours of admission. Inclusion criteria included all patients older than 18 years who were admitted because of TIA according to the ICD9 codes.

Results: Measuring this indicator started in 2015 with 5504 patients and a 58% success rate. The figures for the years 2016, 2017, and 2018 were 5309, 5447, and 5278 patients with success rates of 73%, 79%, and 83%, respectively. Six of 26 hospitals (23.0%) reached the target of 80% in 2018. From 2015 to 2018 a total of 21,538 patients were admitted to emergency departments in Israel and diagnosed with TIA. Of these, 15,722 (72.9%) underwent duplex within 72 hours. The mortality rate within 30 days from diagnosis was 0.81% in patients who performed duplex within 72 hours of diagnosis and 2.37% in patients who did not, odds ratio 2.676, 95% confidence interval 2.051–3.492, P < 0.0001. These results indicate a statistically significant decrease of 65.82%.

Conclusions: A significant decrease in mortality was noted in patients with a new diagnosis of TIA who underwent duplex within 72 hours of diagnosis

Background: The coronavirus disease-2019 (COVID-19) outbreak had an effect on healthcare.

Objectives: To evaluate the presentation and management of patients with acute appendicitis.

Methods: A retrospective study was conducted of all patients presenting with acute appendicitis to the emergency department of a large tertiary center during March and April 2020. Clinical features, diagnostic workup, and management were compared.

Results: Seventy-four patients presented with acute appendicitis during the pandemic compared to 60 patients during the same time the year before. There were no significant differences in patient demographics: age (P = 0.65), gender (P = 0.73), smoking status (P = 0.48). During COVID-19 patients were more likely to complain of right lower quadrant pain (100% vs. 78.3%, P < 0.01). Rates of surgical treatment was similar (83.8% vs. 81.7%, P = 1); mean operative time was longer during COVID-19 (63 ± 23 vs. 52 ± 26 minutes, P = 0.03). There were no significant differences in intra-operative findings including the presence of appendiceal perforation (16.3% vs. 14.5%, P = 0.8), abscess (6.1% vs. 9.7%, P = 0.73), or involvement of cecum or terminal ileum (14.28% vs. 19.63%, P = 1). Postoperative treatment with antibiotics was more prevalent during COVID-19 (37.1% vs. 18%, P = 0.04). Length of stay (1.82 ± 2.04 vs. 2.74 ± 4.68, P = 0.2) and readmission rates (6% vs. 11.3%, P =0.51) were similar.

Conclusion: The COVID-19 pandemic did not significantly affect the presentation, clinical course, management, and outcomes of patients presenting with acute appendicitis.

Background: Pancreatic trauma is uncommon in pediatric patients and presents diagnostic and therapeutic challenges. While non-operative management (NOM) of minor pancreatic injuries is well accepted, the management of major pancreatic injuries remains controversial.

Objectives: To evaluate management strategies for major blunt pancreatic injury in children.

Methods: Data were retrospectively collected for all children treated for grade III or higher pancreatic injury due to blunt abdominal trauma from 1992 to 2015 at two medical centers. Data included demographics, mechanism of injury, laboratory and imaging studies, management strategy, clinical course, operative findings, and outcome.

Results: The cohort included seven boys and four girls aged 4–15 years old (median 9). Six patients had associated abdominal (mainly liver, n=3) injuries. The main mechanism of injury was bicycle (handlebar) trauma (n=6). Five patients had grade III injury and six had grade IV. The highest mean amylase level was recorded at 48 hours after injury (1418 U/L). Management strategies included conservative (n=5) and operative treatment (n=6): distal (n=3) and central (n=1) pancreatectomy, drainage only (n=2) based on the computed tomography findings and patient hemodynamic stability. Pseudocyst developed in all NOM patients (n=5) and two OM cases, and one patient developed a pancreatic fistula. There were no differences in average length of hospital stay.

Conclusions: NOM of high-grade blunt pancreatic injury in children may pose a higher risk of pseudocyst formation than OM, with a similar hospitalization time. However, pseudocyst is a relatively benign complication with a high rate of spontaneous resolution with no need for surgical intervention.

Hospitalization of ulcerative colitis patients is needed in severe exacerbation of the disease or for managing complications. In this systematic review and meta-analysis the prevalence of hospitalization in ulcerative colitis and possible predictive factors are discussed. A systematic literature search of English language publications that were published before 31 December 2019 was conducted. Retrospective cohort studies describing hospitalizations of UC patients were included. Meta-analysis was performed by using comprehensive meta-analysis software. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated for the number of patients hospitalized. Seven studies and 15 datasets were found that fulfilled the inclusion criteria. In total, the studies included 2067 patients from six countries. The event rates for the number of patients hospitalized in a follow-up duration of 42,320 patient-years and for the number of patients underwent operation in a follow-up of 24,650 patient-years were 0.065 (95%CI 0.063–0.068) and 0.019 (95%CI 0.017–0.021), respectively. More studies during the era of biologics need to be performed to identify the factors predictive of hospitalization and surgery with UC. Prevention of inflammation and UC complications may prevent hospitalization and the need for surgical treatment

Background: The novel coronavirus disease (COVID-19) pandemic changed medical environments worldwide.

Objectives: To evaluate the impact of the COVID-19 pandemic on trauma-related visits to the emergency department (ED).

Methods: A single tertiary center retrospective study was conducted that compared ED attendance of patients with injury-related morbidity between March 2020 (COVID-19 outbreak) and pre-COVID-19 periods: February 2020 and the same 2 months in 2018 and 2019.

Results: Overall, 6513 patients were included in the study. During the COVID-19 outbreak, the daily number of patients visiting the ED for acute trauma declined by 40% compared to the average in previous months (P < 0.01). A strong negative correlation was found between the number of trauma-related ED visits and the log number of confirmed cases of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Israel (Pearson's r = -0.63, P < 0.01). In the COVID-19 period there was a significant change in the proportion of elderly patients (7% increase, P = 0.002), admissions ratio (12% increase, P < 0.001), and patients brought by emergency medical services (10% increase, P < 0.001). The number of motor vehicle accident related injury declined by 45% (P < 0.01).

Conclusions: A significant reduction in the number of trauma patients presenting to the ED occurred during the COVID-19 pandemic, yet trauma-related admissions were on the rise

Background: The antibiotic resistance profile of Helicobacter pylori (H. pylori) is constantly changing. Up-to-date and reliable data for the effectiveness of first-line H. pylori treatment protocols are necessary to provide evidence-based best-practice guidelines.

Objectives: To determine the effectiveness, compliance and safety of first-line treatment for H. pylori in Israel.

Methods: An observational, prospective, multicenter study was conducted in tertiary referral centers in Israel, as part of the European registry on H. pylori management (Hp-EuReg). H. pylori-infected patients were included from 2013 to March 2020. Data collected included demographics, clinical data, diagnostic tests, previous eradication attempts, current treatment, compliance, adverse events, and treatment outcome result.

Results: In total, 242 patients were registered, including 121 (50%) who received first-line therapy, 41% of these individuals received clarithromycin based triple therapy and 58.9% received a four-drug regimen. The overall effectiveness of first-line therapy was 85% and 86% by modified intention-to-treat and per protocol analyses, respectively. The effectiveness of both sequential and concomitant therapies was 100% while clarithromycin-based triple therapy achieved an eradication rate of 79%. Treatment eradication was higher among patients who received high dose proton pump inhibitor (PPI) compared to those treated with low dose PPI (100% vs. 81.5% respectively, P < 0.01). No difference in treatment effectiveness was found between 7-, 10-, and 14-day treatment.

Conclusions: The effectiveness of clarithromycin-based triple therapy is suboptimal. First-line treatment of H. pylori infection should consist of four drugs, including high dose PPI, according to international guidelines.

Background: The World Health Organization classified coronavirus disease-19 (COVID-19) as a pandemic and recommends strict restrictions regarding most aspects of daily activities.

Objectives: To evaluate whether the pandemic has changed the prenatal care and pregnancy outcome in pregnant women without COVID-19.

Methods: The authors conducted a cross-sectional study to describe changes in outpatient clinic visits and to compare the rates of cesarean and instrumental deliveries between two periods of time: March–April 2020 (during the COVID-19 outbreak) with March–April of the preceding year, 2019.

Results: During the COVID-19 outbreak, visits to obstetric triage, gynecologic triage, high-risk clinic, and ultrasound units decreased by 36.4%, 34.7%, 32.8%, and 18.1%, respectively. The medical center experienced a 17.8% drop in the total number of births (610 births) compared with March and April 2019 (742 births). During the outbreak women were more likely to be nulliparous (33.3% vs. 27.6%, P = 0.02) and present with hypertensive disorders during pregnancy (7.5% vs. 4%, P = 0.005) or gestational diabetes (13% vs. 10%, P = 0.03). More epidural analgesia was used (83.1% vs. 77.1%, P = 0.006). There were more operative vaginal deliveries during the outbreak (16.7% vs. 6.8%, P = 0.01). All other maternal and neonatal outcomes were comparable between the two periods.

Conclusions: The medical facility experienced a major decline in all aspects of the routine obstetrics activities during the time of the pandemic. The higher rate of operative vaginal deliveries among nulliparous may be associated with the pandemic effect on the rate of high-risk patients

Background: The introduction of pneumococcal conjugate vaccine-13 (PCV-13) has reduced the burden of invasive pneumococcal disease.

Objective: To characterize true positive blood cultures of children who presented to our hospital following implementation of the PCV-13 vaccine.

Methods: A retrospective study was conducted on positive blood cultures of children presenting with fever from 2010–2017. Subjects were divided into two age groups: a younger group 3–36 months and an older group 3–18 years. Patients were classified as either having or not having a focus of infection at the time of their bacteremia. Pneumococcal isolates were typed at Israel's Streptococcal Reference Laboratory.

Results: The samples included 94 true positive blood cultures. Focal infection with concomitant bacteremia was more common than bacteremia without a focus both overall: 67/94 (71%) vs. 27/94 (28.7%), P <0.001 as well as in the two groups: 32/48 (66%) vs. 16/48 (33%), P = 0.02 in the younger group and 35/46 (76%) vs. 11/46 (24%), P = 0.001 in the older group. Streptococcus pneumoniae was the most common pathogen overall, 27/94 (29%), and in the younger group, 21/48 (44%), but rare in the older group, 6/46 (13%). In the latter, Brucella species predominated, 12/46 (26%), along with Staphylococcus aureus 12/46 (26%).

Conclusions: Our findings are consistent with other studies reporting decreased pneumococcal bacteremia, bacteremia primarily accompanying focal infection, and changing etiological agents among PCV-13-vaccinated children. Brucella species was prominent in older children with osteoarticular infections. Ongoing surveillance is warranted to better understand the implications of PCV-13.

Despite advances in therapeutic modalities, especially with biologic treatments, the number of hospitalizations due to complications for Crohn's disease did not decrease. We examined the prevalence and possible predictive factors of hospitalizations in Crohn's disease. A systematic literature search was conducted until 31 October 2018. Relevant studies were screened according to established protocol. Retrospective cohort studies describing hospitalizations of Crohn's disease patients were included. Meta-analysis was performed by using comprehensive meta-analysis software. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated for the number of patients hospitalized. Twelve studies published before 31 March 2018 fulfilled the inclusion criteria and were comprised of 23 data-sets and included 4421 patients from six countries. A funnel plot demonstrates a moderate publication bias. We reported the event rates for the number of patients hospitalized, in a follow-up survey of 20,987 patient-years, and for the patients who underwent surgery in a follow-up of 5061 patient-years, with ORs of 0.233 with 95%CI 0.227–0.239, and 0.124 with 95%CI 0.114–0.135 (P < 0.001), respectively. Thus, when collecting the data from 12 cohort studies we found that hospitalization takes place in 23.3% of the patients, and operation in 12.4% along their disease duration. Patients with Crohn's disease may be hospitalized due to exacerbation of their inflammatory disease, because of non-inflammatory disease (such as fistula or stricture), or due to medical complications. The goal of therapy should be to keep the Crohn's disease patients in their natural environment and out of the hospital and to prevent surgery as much as possible.
