Background: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) is associated with decreased perioperative morbidity and mortality.

Objectives: To report the outcomes of EVAR among patients older than 80 years of age.

Methods: In this retrospective study, we reviewed patients older than 80 years of age who underwent elective EVAR at our institution between 2007 and 2017. The demographics, perioperative morbidity and mortality, and long-term results are reported.

Results: During the study period, 444 patients underwent elective EVAR for AAAs. Among them 128 patients (29%) were > 80 years of age. Mean age was 84 ± 3.4 (range 80–96) years, and 110 patients (86%) were male. The EVAR was technically successful in 127 patients (99%) and there were intraoperative mortalities. Within 30 days of the surgery, nine patients (7%) died. Major and minor adverse events occurred in 26 (20%) and 59 (46%) patients, respectively. Factors associated with increased risk of perioperative morbidity and mortality included chronic kidney disease, peripheral artery disease, and the existence of three or more co-morbidities.

Conclusions: EVAR in the elderly can be performed with a high rate of success; however, it is associated with a substantial rate of morbidity and mortality, particularly when patients present with multiple co-morbidities. When performing EVAR in this population group, the risk of rupture must be considered opposed to the life expectancy of these patients and the risk of perioperative morbidity and mortality.

Background: Older age is an independent predictor of worse outcome from traumatic brain injury (TBI). No clear guidelines exist for the management of TBI in elderly patients.

Objectives: To describe the outcomes of elderly patients presenting with TBI and intracranial bleeding (ICB), comparing a very elderly population (≥ 80 years of age) to a younger one (70–79).

Methods: Retrospective analysis of the outcomes of elderly patients presenting with TBI with ICB admitted to a level I trauma center.

Results: The authors analyzed 100 consecutive patients aged 70–79 and 100 patients aged 80 and older. In-hospital mortality rates were 9% and 21% for groups 70–79 and ≥ 80 years old, respectively (P = 0.017). Patients 70–79 years old showed a 12-month survival rate of 73% and a median survival of 47 months. In patients ≥ 80 years old, 12-month survival was 63% and median survival was 27 months (P = NS). In patients presenting with a Glasgow Coma Scale score of ≥ 8, the in-hospital mortality rates were 41% (n=5/12) and 100% (n=8/8). Among patients ≥ 80 years old undergoing emergent surgical decompression, in-hospital mortality was 66% (n=12/18). Survivors presented with a severe drop in their functional score. Survival was dismal in patients ≥ 80 years old who were treated conservatively despite recommended operative guidelines.

Conclusions: There is a lack of reliable means to evaluate the outcome in patients with poor functional status at baseline. The negative prognostic impact of severe TBI is profound, regardless of treatment choices.

In non-ambulatory patients with cerebral palsy, the presence of scoliosis has a major impact on health and quality of life. The aim of this review is to raise awareness of caregivers from various professions to the extent of the problem, to explain the natural history of neuromuscular scoliosis and its pathophysiology, and to describe up-to-date optional conservative and surgical treatments.

Background: Recently, Israel established the first national-level adult cardiac surgery database, which was linked to the Society of Thoracic Surgeons (STS).

Objectives: To validate and compare the STS predicted risk of mortality (PROM) to logistic EuroSCORE I (LESI) and EuroSCORE II (ESII) in Israeli patients undergoing cardiac surgery.

Methods: We retrospectively studied 1279 consecutive patients who underwent cardiac surgeries with a calculable PROM. Data were prospectively entered into our database and used to calculate PROM, LESI, and ESII. Scores were normalized and correlated using linear regression and Pearson's test. To examine model calibration, we plotted the total observed versus expected mortality for each score and across five risk-score subgroups. Model discrimination was assessed by measuring the area under the receiver operating curves.

Results: The observed 30-day operative mortality was 1.95%. The median (IQ1; IQ3) PROM, LESI, and the ESII scores were 1.45% (0.69; 3.22), 4.54% (2.28; 9.27), and 1.88% (1.18; 3.54), respectively, with observed over expected ratios of 0.63 (95% confidence interval [95%CI] 0.42–0.93), 0.59 (95%CI 0.40–0.87), and 0.24 (95%CI 0.17–0.36), respectively, (STS vs. ESII P = 0.36, STS vs. LESI P = 0.0001). There was good correlation among all scores. All models overestimated mortality. Model discrimination was high and similar for all three scores. Model calibration of the STS, PROM, and ESII were more accurate than the LESI, particularly in higher risk subgroups.

Conclusions: All scores overestimated mortality. In Israeli patients, the STS, PROM, and ESII risk-scores were more reliable metrics than LESI, particularly in higher risk patients.

Background: Whole-body integrated positron emission tomography / contrast-enhanced computed tomography (PET/CT) scan is increasingly used in cutaneous lymphomas. However, the value of PET/CT in the detection of cutaneous lesions in primary cutaneous B-cell lymphoma (PCBCL) has barely been investigated.

Objectives: To investigate the diagnostic accuracy of PET/CT in tracking cutaneous involvement in PCBCL.

Methods: A retrospective study was conducted on 35 consecutive patients diagnosed with cutaneous B-cell lymphoma according to the World Health Organization classification who were evaluated with PET/CT as the initial staging procedure before treatment.

Results: Thirty-five patients met the study criteria. In two patients extracutaneous disease was detected by PET/CT and CT and confirmed by biopsy. Of the 33 patients with PCBCL, 26 (79%) had small cell PCBCL (18 marginal-zone, 8 follicle-center lymphoma) and 7 (21%) had large cell PCBCL (3 follicle-center, 3 leg-type, 1 indeterminate). PET/CT detected skin lesions in 3 of 26 patients (12%) with small-cell PCBCL as compared to 6 of 7 patients with large-cell PCBLC (86%), a 7.4-fold detection risk (95% confidence interval, 2.4–22, P = 0.004). The PET-positive subgroup was characterized by larger lesion size (P < 0.001) and a higher Ki-67 proliferation index (P < 0.001).

Conclusions: The sensitivity of PET/CT for detecting cutaneous involvement of lymphomas is low for small-cell PCBCL but high for large-cell types, and thus may facilitate therapeutic strategies.

Background: Fibromyalgia is a syndrome of unknown etiology that is characterized by widespread pain, which severely impairs quality of life. Several forms of occupational and alternative therapy have demonstrated beneficial effects in fibromyalgia patients.

Objective: To assess the effects of participation in a floral design course on physical and psychiatric symptoms in a cohort of fibromyalgia patients.

Methods: This study was conducted as an observational study. Women diagnosed with fibromyalgia over the age of 18 were recruited to participate in one of two 12-week flower design (floristry) courses. Demographic details, disease activity indices, and anxiety and depression scores were calculated for all participants at baseline, week 12, and study completion. Physical and mental health of the two groups were compared throughout the study time-points.

Results: The study was completed by 61 female fibromyalgia patients who were included in the final analyses; 31 patients participated in the first floristry course and 30 in the second. Significant improvements in the 36-Item Short Form Survey physical and mental health components, visual analog scale, Fibromyalgia Impact Questionnaire, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale scores for the entire study population and for each group separately could be seen following participation in each floristry course.

Conclusions: Participation in a floristry course may lead to a significant improvement in pain and psychiatric symptoms in fibromyalgia patients. These findings highlight the potential benefit of utilizing occupational therapy programs, such as a floristry course, for improving quality of life in fibromyalgia.

Background: Cannabinoid hyperemesis syndrome (CHS) is under-recognized by clinicians. It is characterized by nausea, severe abdominal pain, and cyclical vomiting in the context of chronic cannabis use. Oral benzodiazepine is a proposed treatment for CHS. It decreases activation of Cannabinoid Type 1 Receptor (CB1) in the frontal cortex, has a sedative and hypnotic effect and reduces the anticipation of nausea and vomiting. These effects on the central nervous system (CNS) might explain its beneficial antiemetic effect for this syndrome.

Objectives: To increase the index of suspicion for CHS, a unique syndrome that requires a unique treatment with benzodiazepines and not antiemetics.

Methods: We describe a series of four patients with documented cannabis use, who were admitted to an internal medicine department of Meir Medical Center due to symptoms consistent with abdominal pain, nausea, and vomiting. They were initially treated with conventional antiemetics and proton pump inhibitors without response. Intensive investigations were conducted to exclude common and sometimes urgent gastrointestinal or CNS syndromes.

Results: After excluding urgent gastrointestinal and CNS origins for the vomiting, we suspected CHS. All four patients experienced similar symptoms and failure of conventional treatment with antiemetics and proton pump inhibitors. They experienced relief after administration of benzodiazepines.

Conclusions: A high index of suspicion for CHS allows for rapid, appropriate treatment with benzodiazepines, which in turn may lead to cessation of the debilitating symptoms caused by this syndrome.

Background: Pulmonary embolism (PE) is the third most frequently occurring cardiovascular disease. However, the clinical presentation in patients with PE is variable.

Objectives: To evaluate the prevalence of radiological findings detected in contrast-enhanced computed tomography angiography (CTA) and their significance in patients with PE; and to assess whether the CTA findings differed in patients receiving tissue plasminogen activator (tPA) therapy from those who did not.

Methods: We retrospectively reviewed CTA scans of 186 patients diagnosed with acute PE. Incidental findings on CTA scan were assessed, including mediastinal and parenchymal lymph nodes, pleural effusion, space-occupying lesions, consolidations, emphysema, and pericardial effusion.

Results: Patients receiving tPA (19.9%) were less likely to have pleural effusion (29.7% vs. 50.3%, P = 0.024). Other CTA findings did not differ between the tPA and non-tPA groups, including lung infiltrates (40.5% vs. 38.9, P = 0.857), space-occupying lesions (5.4% vs. 6.7%, P = 1), pericardial effusion (8.1% vs. 8.7%, P = 1), emphysema (21.6% vs. 17.4%, P = 0.557), lung (18.9% vs. 24.2%, P = 0.498), and mediastinal ( 24.3% vs. 25.5%, P = 0.883) lymph nodes, respectively.

Conclusion: The prevalence of pleural effusion (unilateral or bilateral) was higher in patients not treated with tPA. Therefore, in patients with a borderline condition, the presence of pleural effusion could support the decision not to give tPA treatment.

Background: Adverse drug events (ADEs) are a major cause of morbidity and mortality worldwide. Hence, identifying and monitoring ADEs is of utmost importance. The Trigger Tool introduced by the Institute of Healthcare Improvement in the United States has been used in various countries worldwide, but has yet to be validated in Israel.

Objective: To validate the international Trigger Tool in Israel and to compare the results with those generated in various countries.

Methods: A retrospective descriptive correlative analysis surveying four general hospitals in Israel from different geographical regions was conducted. Patient medical charts (n=960) were screened for 17 established triggers and confirmed for the presence of an ADE. Trigger incidence was compared to the actual ADE rate. Further comparison among countries was conducted using published literature describing Trigger Tool validation in various countries.

Results: A total of 421 triggers in 279 hospitalizations were identified, of which 75 ADEs in 72 hospitalizations (7.5%) were confirmed. In addition, two ADEs were identified by chart review only. Mean positive predictive value was 17.81% and overall sensitivity was 97%. We found 1.54 ADEs for every 100 hospitalization days, 7.8 ADEs per 100 admissions, and 1.81 ADEs for every 1000 doses of medication. Of the 77 ADEs identified, 22.7% were defined as preventable.

Conclusions: Our results support the Trigger Tool validity in Israel as a standardized method. Further studies should evaluate between hospital and region differences in ADE rate, in particular for the preventable events.
