Background: Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives: To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods: A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results: We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.

Background: The MitraClip procedure is becoming an acceptable alternative for high-risk patients with mitral regurgitation (MR) due to functional (FMR) or degenerative (DMR) disease and suitable mitral anatomy.

Objectives: To evaluate the results of MitraClip at our institute in carefully selected patients.

Methods: We conducted a retrospective analysis of medical records and echocardiography data from January 2012 to December 2017.

Results: A total of 39 MitraClip procedures in 37 patients (aged 75 ± 12 years, 9 women) was performed. Twenty-four patients presented with FMR, 12 with DMR, and 1 with combined pathology. One-day post-procedure MR was moderate to low in 86.1% of patients, with immediate device success in 88.8%. MR at 1 year was moderate to low in 79% at 1 year. Survival at 1 year was 86% and at 2 years 69.4%. Peri-procedural (< 1 week) death and MitraClip failure occurred in one and three patients, respectively. New York Heart Association score improved to class 1 or 2 in 37% of patients at 1 year vs. one patient at baseline. Post-procedural systolic pulmonary pressure was reduced from 53 (range 48–65) to 43 (range 36–52) mmHg at 1 month with a subsequent plateau at follow-up, to 41 (34–57) mmHg at 6 months, and to 47 (38–50) at 12 months.

Conclusions: MitraClip in severe MR resulted in modest improvement in functional status and pulmonary pressure with a small risk of immediate procedural complications. Outcomes are encouraging considering the natural course of MR and the risks of surgical intervention.

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: 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: The Israel Poison Information Center (IPIC), Rambam Health Care Campus, provides 24-hour telephone consultations on clinical toxicology and drug and reproductive toxicology. It participates in research, teaching and regulatory activities, and provides laboratory services. In 2014, nurse specialists in poison information joined the IPIC.

Objectives: To report the epidemiology of poison exposures in Israel.

Methods: We present computerized queries and a descriptive analysis of the medical records database of the IPIC for 2017.

Results: A total of 39,928 poison exposure cases were recorded, reflecting increases of 226.3% and 26.7% compared with 1995 and 2012, respectively. Children < 6 years of age were involved in 47.0% of cases; 80.4% of calls were made by the public and 17.8% by physicians; 74.2% of exposures were unintentional and 7.3% intentional. Pharmaceuticals were involved in 51.4% of cases, chemicals in 36.9%, bites and stings in 2.2%, and plants and mushrooms in 1.5%. Substances most frequently involved were analgesics, cleaning products, and antimicrobials. Clinical severity was moderate/major in 3.3%, mainly due to insecticides, drugs of abuse, and corrosives. Three fatalities were recorded (due to colchicine, organophosphates, and volatile substance inhalant abuse).

Conclusions: Poison exposures and poisonings have markedly increased in Israel, contributing substantially to morbidity. The IPIC prevented unnecessary referrals to emergency departments. Its database is a valuable national resource for collecting and monitoring poisoning exposure cases. It can be used as a real-time surveillance system for the benefit of public health. It is recommended that reporting to the IPIC become mandatory, and its activities adequately supported by national resources.

Background: Pericardial biopsies are rarely performed during the diagnosis and management of pericardial diseases. The circumstances and clinical profile of patients undergoing pericardial biopsies are largely uncharacterized.



Objectives: To examine the circumstances in which pericardial biopsies are obtained and to evaluate their diagnostic yield.



Methods: We studied a total of 100 cases (71% males, mean age 60.8 years, range 8.1–84.5 years) of surgically resected pericardium specimens obtained from 2000 to 2015 at Sheba Medical Center, the largest medical center in Israel. Patients were classified into groups according to four major histological etiologies: idiopathic pericarditis, constrictive pericarditis, malignant pericarditis, and post-cardiac injury syndrome (PCIS). The clinical history and course, laboratory, echocardiography, and histological results were reviewed retrospectively.



Results: Causes of pericarditis according to histological definitions included idiopathic pericarditis (29%), constrictive pericarditis (29%), PCIS (9%), and malignant pericarditis (26%). Overall sensitivity of the pericardial biopsy in patients with malignancy was 57.7%. During the study period, we found a trend toward an increased number of biopsies due to constrictive pericarditis and PCIS, along with a decrease in the number of biopsies performed in patients with malignant or idiopathic pericarditis. The diagnosis following biopsy did not change for any of the patients.



Conclusions: Our findings suggest a low diagnostic yield from pericardial biopsies, especially in malignant pericarditis. This conclusion, along with novel therapies, resulted in the infrequent use of pericardial biopsy in recent years.

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: The currently accepted treatment for idiopathic sudden sensorineural hearing loss (ISSHL) is systemic steroids as first-line and intratympanic steroids as salvage therapy. Intratympanic (IT) treatment is applied worldwide in many different ways with no universally accepted protocol.

Objectives: To present the current disparity in ISSHL management and to discuss the necessity for establishing a common national protocol.

Methods: In 2014 we conducted a national survey by sending questionnaires on ISSHL management to otologists in every otolaryngology department in the country.

Results: The majority of otolaryngology departments (56%) admit patients with sudden sensorineural hearing. Almost two-thirds (61%) of departments recommend supplementary initial treatment in addition to systemic steroids. None of the medical centers offer intratympanic steroid treatment as primary therapy, but 94% offer this treatment as a salvage therapy. Fewer than half the medical centers (44%) consider the maximal period for intratympanic therapy to be 4 weeks since hearing loss appears. Almost half (48%) the departments use intratympanic steroids once every 5–7 days, usually in an ambulatory setting. Almost half (44%) the medical centers tend to use not more than four courses of IT steroids. In 44% of departments an audiogram is performed at the beginning and at the end of the intratympanic course.

Conclusions: Our results demonstrate a variability among Israeli medical centers in many aspects of intratympanic treatment. We believe this reinforces the need for a comparative international study in order to establish a standard protocol.
