Background: Selective management of stable patients with anterior abdomen stab wounds (AASWs) has become a gold standard management approach throughout the world. Evidenced-based options for supporting selective management include clinical follow-up, local wound exploration with or without diagnostic peritoneal lavage, diagnostic laparoscopy, and abdominal computerized tomography. The presence of multiple AASWs might signify a more aggressive attack and limit the safety of a selective management approach.

Objectives: To evaluate whether multiple AASWs are associated with an increased risk of intra-abdominal injury requiring emergency surgery.

Methods: We retrospectively reviewed all AASW patients admitted to Assaf Harofeh Medical Center, Zerifin, Israel, and Hillel Yaffe Medical Center in Hadera, Israel, from 2007 to 2015. Patients were divided into two groups based on the number of stab wounds: single or multiple. Data were coded for demographics, severity of injury, presence of intra-abdominal injury, laparotomy rate, length of hospital stay (LOS), length of stay in the intensive care unit (LICU), and survival.

Results: The study included 169 patients. Of these, 143 patients had a single AASW and 26 had multiple AASWs. There were no differences between the groups regarding demographics, severity of injury, intra-abdominal penetration, specific organ injury, LOS, or LICU. There was no difference in the percentage of patients requiring laparotomy. The overall mortality was 2.36% (4/169). There was no significant difference in the mortality rate between the groups (P = 0.11).

Conclusions: The presence of multiple AASWs is not a risk factor for increased frequency and severity of intra-abdominal injury.

Background: Reports of longevity in Holocaust survivors (HS) conflict with excess prevalence of chronic diseases described among them. However, data on their long-term risk of cardiovascular diseases (CVD) are limited. Clinical data on large representative groups of HS who were exposed to severe persecution are also limited.

Objectives: To determine the prevalence of CVD and the risk factors in a large cohort of elderly HS compared to elderly individuals who were not exposed to the Holocaust (NHS).

Methods: CVD prevalence rates and risk factors data from the computerized system of the central district of Clalit Health Services, the largest Israeli health maintenance organization (HMO) in Israel were evaluated in a retrospective observational study. The study was comprised of 4004 elderly HS who underwent direct severe persecution. They were randomly matched by identification numbers to 4004 elderly NHS.

Results: HS were older than NHS and 51% of them were older than 85 years. The prevalence rate of ischemic heart disease (IHD) was significantly higher among HS. HS underwent significantly more cardiac interventions (20% vs. 15.7%, P < 0.05). HS status was an independent risk factor for increased IHD and for more coronary interventions.

Conclusions: Despite having a higher prevalence of CVD, a substantial number of HS live long lives. This finding may imply both unique resilience and ability to cope with chronic illness of the survivors as well as adjusted medical services for this population. These findings may help in planning the treatment of other mass trauma survivors.

Background: Multidisciplinary biopsychosocial rehabilitation for patients presenting with rheumatic diseases has been shown to produce better results in a warm climate. Dead Sea Climatotherapy (DSC) has been successfully used for decades to treat many patients with rheumatic diseases.

Objectives: To evaluate the short-term improvement of Norwegian patients who presented with chronic pain following a multidisciplinary biopsychosocial approach to treatment combined with DSC. Both objective and subjective clinical parameters were evaluated.

Methods: This retrospective study included a statistical analysis of 938 patients presenting with rheumatoid arthritis and ankylosing spondylitis (n=105), osteoarthritis (n=342), fibromyalgia (n=374), and other orthopedic conditions (n=117). Clinical assessments were conducted before and after a 3 week treatment program at the Dead Sea.

Results: Six parameters improved significantly in the rheumatoid arthritis and ankylosing spondylitis group as well as in the osteoarthritis group. Five parameters in the fibromyalgia group improved, while two improved in the orthopedic conditions group. Overall, major significant changes occurred in the pain self-assessment, joint motility, and daily activities scores.

Conclusions: A 3-week multidisciplinary biopsychosocial program combined with DSC induced positive changes in the clinical parameters of Norwegian patients presenting with chronic musculoskeletal pain.

Background: Lower extremities ulcers (LEU) are associated with considerable morbidity and mortality. With longer life expectancy, the prevalence of LEU in developed countries is assumed to grow, necessitating an increased demand for treatment by specialists. 

Objectives: To compare the effectiveness of a telemedicine video conferencing modality with the conventional face-to-face treatment of LEU. 

Methods: The study was conducted in conjunction with a two-million member healthcare organization in Israel (Maccabi Healthcare Services). Consecutive visits of patients to wound care specialists during a 12-month observation period reviewed in 2015 were valuated. A nurse-assisted setting was implemented during all treatment sessions. The same specialist supervised patients in both modalities. 

Results: A sample of 111 patients (n=55 in the telemedicine group; n=56 in the face-to-face group) with 593 visits was analyzed. No significant difference in healing of LEU (78.2% in telemedicine vs. 75.0% in face-to-face) was detected, P = 0.823. A reduced number of visits in telemedicine (4.36 ± 2.36) compared to the face-to-face care (6.32 ± 4.17) was shown, P = 0.003. Non-inferiority of telemedicine demonstrated within the Δ = 15% range limits and 80% statistical power was demonstrated. 

Conclusions: Compared to the usual face-to-face method, synchronous video conferencing-based telemedicine may be a feasible and efficient method for LEU management. 

 

Background: Falls while turning are associated with increased risk of hip fracture in older adults. Reliable and clinically valid methods for turn ability assessments are needed.

Objectives: To explore the inter-observer reliability and known group validity of the TURN 180 test.

Methods: We divided 78 independent older adults (mean age 76.6 ± 6.5 years) into three groups: non-fallers, infrequent fallers (1–2 falls per year), and recurrent fallers (> 2 falls per year). Participants underwent performance-based tests: Timed Up and Go (TUG), Performance Oriented Mobility Assessment (POMA), and Berg Balance Scale (BBS). TUG was videotaped for later analysis of the TURN 180 test by two blinded observers.

Results: A significant difference was found in the TURN 180 test parameters among the groups (P < 0.04). TURN 180 was highly correlated with TUG (r = 0.81–0.89, P < 0.001) and BBS (r = -0.704–0.754, P < 0.0001) and moderately with POMA (r = -0.641–0.698, P < 0.0001). The number of steps was found to be the strongest parameter to determine fallers among older adults (specificity 96.3%, sensitivity 40%). Inter-rater reliability (intraclass correlation coefficient 0.91–0.96, P < 0.0001) was found to be excellent for the number of steps, time taken to accomplish a turn, and total test score categories.

Conclusions: The TURN 180 test is highly reliable and can identify the older adults who fall. Our results show that the TURN 180 test can serve as a good performance-based examination for research or clinical setting.

Background: The number of patients undergoing shoulder arthroplasty is increasing yearly.

Objectives: To evaluate the results of a consecutive series of patients who underwent shoulder replacement for a variety of indications in a single medical center in Israel.

Methods: All shoulder arthroplasties performed in our institution between 2006 and 2015 were retrospectively reviewed. The functional outcomes and satisfaction of 180 shoulder arthroplasties were evaluated for objective and subjective parameters using the American Shoulder and Elbow Surgeons Shoulder Score (ASES), the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, and the Short Form Health Survey (SF-12).

Results: The indications for surgery were osteoarthritis (n=35), rotator cuff arthropathy (n=32), fractures (n=99), and other reasons (n=14). The mean follow-up was 52 months. The scores improved markedly among the patients who underwent surgery later in the study period. The mean DASH score before 2012 was 48.8 and improved to 37.2 after 2013. The respective ASES also improved from 54.2 to 68.6. The use of hemiarthroplasty decreased from 85% to 33% as of 2013, while the use of total shoulder arthroplasty increased.

Conclusions: Shoulder arthroplasty represents an effective treatment modality with satisfactory functional outcomes. Our current study demonstrates a shift from hemiarthroplasty to total shoulder arthroplasty, with the number of procedures increasing yearly. Surgeon experience and the expanding volume of operations had a direct positive effect on the functional outcomes of shoulder arthroplasties.

Background: Although women comprise only a minority of patients hospitalized due to violence-related injury, the circumstances of attacks against women may make their injuries more severe.

Methods: We conducted a retrospective study using data of 9173 patients with stabbing-related injuries from 19 trauma centers participating in the Israeli National Trauma Registry between 1 January 1997 and 31 December 2014. Male and female patients were compared in terms of demographic and circumstantial factors, clinical characteristics, and outcomes.

Results: Women were found to have greater injury severity according to the Injury Severity Scale (ISS) – 18% vs. 11% of severe (ISS 16+) injuries – requiring more hospital resources. Injuries that contributed most to injury severity in the female population were head and severe abdominal trauma. Women also sustained injuries to more body sites than men; however, regression analysis showed that the contribution of this factor to the overall difference in injury severity was less important than the injured sites. Regression analysis among severely injured patients pointed at injury to lower extremities as an independent factor related to female mortality. Different from men, among women the stabbing injuries to the upper extremities were not a protective factor in terms of mortality.

Conclusions: There are significant differences in the injury profiles of male and female stabbing victims, which can be explained by the different circumstances of the injury event.

Background: Gender differences in adolescent idiopathic scoliosis (AIS) have been documented in curve progression, response to bracing, and outcomes of surgical treatment. However, limited information is available about the relation between gender and scoliosis curve patterns and radiographical characteristics.

Objectives: To evaluate the effect of gender on curve pattern and compare clinical and radiographical characteristics between male and female patients with AIS.

Methods: We conducted a retrospective review of prospectively collected data that compared clinical and radiographical characteristics between male and female surgical candidates. Demographic and clinical data including age at presentation, gender, family history of scoliosis, brace treatment history, clinical coronal balance, shoulder asymmetry, and hump size were recorded. All patients graded their pain with the use of a visual analogue scale (VAS) on a scale from 0 to 10. Radiographs of the spine were reviewed to determine the type of curve according to the Lenke classification, Cobb angle, thoracic kyphosis angle, and the Risser sign. Radiologic coronal balance was recorded. Curve flexibility was determined by measuring the thoracic and lumbar curves magnitude on side bending radiographs

Results: The study included 163 patients with AIS including 35 males and 128 females patients. Although a trend toward more flexible major thoracic curves in females was noticed, there was no statistically significant difference between the 2 groups.

Conclusions: In this study we were not able to demonstrate any clinical nor radiological statistical differences between male and female patients who are candidate for surgical treatment.

Background: A history of childhood sexual abuse (CSA) has been linked to a variety of physical and psychiatric illnesses, including ischemic heart disease and post-traumatic stress disorder (PTSD).

Objectives: To determine the prevalence of past CSA and re-traumatization among hospital psychiatric consultations and to determine whether a CSA group in a hospital setting shared characteristics with community samples described in the literature.

Methods: We divided 228 consecutive psychiatric consultations into two groups. One group comprised patients with a past history of CSA while the other group had no such history. Both groups were further divided into a subgroup that presented with features of re-traumatization.

Results: In the cohort, 38% described a history of CSA. Twenty patients were identified as presenting with features of re-traumatization. There were significant differences between the two groups. The patients with a history of CSA were more likely to have arrived at the emergency department (ED) during the preceding 12 months with a diagnosis of PTSD, personality disorder, and substance use disorder. There was a greater proportion of patients in the CSA group who had grown up in an ultra-Orthodox Jewish household and who currently identified as being secular.

Conclusions: The characteristics of the patients with past CSA in this study are similar to community-based samples, except for a significant gender difference. To the best of our knowledge, this study is the first to investigate CSA history during hospital ED psychiatric consultations. A history of CSA should be considered during psychiatric consultations in a general hospital ED admission.

Background: Frozen section (FS) is often performed when histopathological evaluations are urgently required for implementation of therapeutic measures. In dermatology, this method is most commonly used to evaluate excision margins of tumors. FS are also routinely employed to differentiate toxic epidermal necrolysis from staphylococcal scalded skin syndrome. However, little is currently known about the performance of FS in the diagnosis of inflammatory dermatoses.

Objectives: To compare histopathological diagnoses in a series of patients with a clinical diagnosis of an inflammatory dermatosis for which FS and paraffin-section (PS) specimens were obtained on the same day.

Methods: We conducted a single-center retrospective analysis of 43 cases. All histological slides were reviewed by a single dermato-pathologist. Concordance was calculated between FS and PS.

Results: Patients were divided into three groups according to diagnosis: papulosquamous diseases (group I), drug eruptions (group II), and a heterogeneous group (group III) that included cases of bullous vasculitis and Sweet syndrome. Among the three groups, the results of FS and of PS were discordant only in five cases (5/43, 11.6%). Compared to PS, FS had a sensitivity of 92.9% [95% confidence interval (95%CI) 64.17–99.63%] and a specificity of 100% in group I, sensitivity of 90.9% (95%CI 57.12–99.52%) and specificity of 100% in group II, and sensitivity of 83.33% (95%CI 60.78–94.16%) and specificity of 100% in group III. The degree of agreement between the results of the FS and of the PS was almost perfect (kappa = 0.95, 0.93 and 0.85 respectively).

Conclusions: This study suggests that FS is a valid approach for the rapid diagnosis of inflammatory dermatoses. This method is as specific as PS, although it is less sensitive.

Background: Hyperchloremia is frequent in adult surgical patients and is associated with renal dysfunction. Studies in surgical pediatric patients are lacking.

Objectives: To identify both the incidence of postoperative hyperchloremia in children undergoing surgery for idiopathic and non-idiopathic scoliosis, and the association of postoperative hyperchloremia with intraoperative fluid management and postoperative diuresis.

Methods: The records of 74 children and adolescents who underwent elective scoliosis surgery were retrospectively evaluated. The primary endpoint was the incidence of serum chloride level ≥ 110 mEq/L at the end of surgery and 12 hours postoperatively. Secondary endpoints were the type and volume of administered fluids, 12 hours postoperative diuresis, and the incidence of postoperative oliguria.

Results: Hyperchloremia occurred in 55% of the patients at the end of surgery and in 52% 12 hours postoperatively. Hyperchloremic patients received larger intraoperative volume of 0.9% NaCl diluted cell-saver blood and 10% HAES than did normochloremic patients [median (interquartile range) 6.8 (2.5–11.0) ml/kg vs. 0 (0–7.3), P = 0.003 and 10.0 (0–12.8) vs. 4.4 (0–9.8), P = 0.02, respectively]. Additionally, when compared with normochloremic patients, diuresis during the first 12 hours postoperatively was lower in hyperchloremic patients. Postoperative oliguria (urine output < 0.5 ml/kg/hr for 12 hours) was diagnosed in 7 children (9%), of whom 6 were hyperchloremic at the end of surgery.

Conclusions: Early postoperative hyperchloremia is common in children undergoing scoliosis repair surgery and may be attributed to the administration of 0.9% NaCl diluted cell-saver blood and 10% HAES. Postoperative hyperchloremia might be associated with postoperative oliguria.

Background: Respiratory syncytial virus (RSV)-related bronchiolitis is a common cause of morbidity in young infants. The recommendations for its passive prevention by palivizumab are currently under intensive debate.

Objectives: To elucidate the optimal prevention strategy by studying the morbidity of RSV disease under the current recommendations for palivizumab prophylaxis in Israel.

Methods: We collected demographic and clinical data of all children hospitalized with microbiologically confirmed RSV bronchiolitis during 2015–2016 at Schneider Children's Medical Center. The seasonality of RSV disease was also studied for the period 2010–2017 in sentinel clinics scattered throughout Israel.

Results: Of the 426 hospitalized children, 106 (25%) had underlying diseases but were not eligible for palivizumab prophylaxis according to the current criteria in Israel. Their course was severe, with a mean hospital stay of 6.7 days and a 12% admission rate to the pediatric intensive care unit (PICU). Palivizumab-eligible children who did not receive the prophylaxis before hospitalization had the most severe course, with 22% admitted to the PICU. More children were diagnosed with RSV disease in October than in March among both hospitalized and ambulatory children; 44% of the palivizumab-eligible hospitalized children were admitted in the last 2 weeks of October, before 1 November which is the recommended date for starting palivizumab administration in Israel.

Conclusions: According to the results of the present study we suggest advancing RSV prophylaxis in Israel from 1 November to mid-October. The precise palivizumab-eligible categories should be reconsidered.

Background: Catheter ablation (CA) is a well-established therapeutic option for patients with recurrent symptomatic atrial fibrillation (AF). Data on gender-related differences are limited with regard to baseline characteristics and long-term success rates of catheter ablation for AF.

Methods: We analyzed a cohort of 251 consecutive patients who underwent a first catheter ablation for AF in our institute during the period 2008 through 2015. All patients were followed by regular annual clinic visits, electrocardiograms, periodic 24–48 hour Holter monitoring, and loop recorders. The primary endpoint was first recurrence of AF during 1 year of follow-up.

Results: The cohort comprised 26% women (n=65), who were older (62.1 ± 9.6 vs. 54.4 ± 11.3 years, P < 0.01) and had a higher proportion of diabetes mellitus (23.1 vs. 5.4%, P < 0.001) than male patients. No other significant differences were evident. At 1 year follow-up, the cumulative survival free of AF was significantly higher in women compared with men (83% vs. 66%, respectively, log rank P value = 0.021). Subgroup analysis showed an interaction between female and small indexed left atrial diameter (LADi < 23 mm/m²).

Conclusions: Our findings suggest that women experience a significantly lower rate of AF recurrence post-CA compared with men. This gender-related advantage appears to be restricted to women without significant left atrial enlargement. It further implies that left atrial enlargement has a stronger negative impact on post-CA AF recurrence in females than in males. Due to the relatively small sample number of females further research is warranted to validate our conclusions.

Background: The aggregation of autoimmune diseases in relatives (AID-R) of patients with systemic sclerosis (SSc) has been reported.

Objectives: To analyze the prevalence of autoimmune diseases in SSc relatives and to compare their features to those of SSc patients without AID-R (controls).

Methods: A case-control analysis compared SSc patients with AID-R to those without AID-R (25 patients) with similar disease duration.

Results: Among 322 patients, 25 (7.7%; 21 females, 41.4 ± 15.6 years of age, disease duration 11 ± 8.6 years) had AID-R (21 had a first-degree relative, 4 had a second-degree relative, and 2 had both). Fourteen patients (56%) and five controls (20%) had an additional autoimmune disease (P < 0.009). Diffuse SSc (48% vs. 24%) and arthritis (72% vs. 28%) were more frequent among the patients with AID-R than the controls (P < 0.05). No significant differences were found regarding lung, heart, vascular, and digestive system involvement. The mean number of additional autoimmune diseases was 0.84 ± 0.94 in AID-R vs. 0.24 ± 0.52 in controls (P < 0.038). The mean number of autoantibodies was 2.8 ± 1.5 and 2.2 ± 0.9 (P < 0.047). Five patients died during follow-up, four of whom had AID-R. Relatives of SSc patients had diverse autoimmune diseases; the prevalence of SSc in scleroderma relatives was 1.86% (2 in first-degree and 6 in second-degree relatives). SSc patients with AID-R had an obvious tendency to polyautoimmunity.

Conclusion: A precise family history is an important clue in prognosis and prediction of autoimmune diseases in SSc patients and their relatives.
