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: 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: Treatment of patients with childhood growth hormone deficiency is usually terminated at the end of puberty. Follow-up into adult age is rare, even more so in patients with congenital isolated growth hormone deficiency (cIGHD).

Objectives: To assess the clinical and social characteristics of adults with cIGHD who received growth hormone (hGH) treatment in childhood.

Methods: Thirty-nine patients (23 men, 16 women) diagnosed in our clinic with cIGHD at 7 ± 4.2 years, and treated with hGH during childhood for 2–18 years, were followed into adulthood (mean age 30.7 ± 13.3 years). Ascertained detailed data were found for 32 patients.

Results: Mean ± SD height for males was 160.2 ± 10.6 cm and for females 146.4 ± 5.4 cm. All patients achieved full sexual development and 14 were married. After cessation of GH treatment and with advanced age all exhibited a progressive increase in adiposity to the degree of obesity. Twelve patients suffered from hyperlipidemia, 4 developed diabetes mellitus, and 5 have cardiovascular diseases. One patient died in an accident. None developed cancer. Of the 39 patients, 22 have an education level of high school or higher, and 2 are in special institutions. Most are employed in manual labor.

Conclusions: Patients with congenital IGHD who do not receive early and regular replacement treatment are prone to lag in achieving normal height and suffer from educational and vocational handicaps.

Background: Temporal trends in the incidence of inflammatory bowel disease (IBD) in the Arab and Jewish populations in Israel have been poorly described.

Objectives: To compare the annual incidence and prevalence rates of Crohn's disease (CD) and ulcerative colitis (UC) in the Arab and Jewish populations in Israel between the years 2003 and 2008.

Methods: We applied a common case identification algorithm to the Clalit Health Services database to both determine trends in age-adjusted incidence and prevalence rates for IBD in both populations during this period and estimate the burden of IBD in Israel.

Results: The incidence of CD in the Arab population increased from 3.1/100,000 in 2003 to 10.6/100,000 person-years in 2008, compared with a decrease in the Jewish population from 14.3/100,000 to 11.7/100,000 person-years for the same period. The incidence of UC in the Arab population increased from 4.1/100,000 in 2003 to 5.0/100,000 person-years in 2008, a low but stable rate, compared with a decrease from 16.4/100,000 to 9.5/100,000 person-years for the same time period in the Jewish population. The prevalence of both diseases increased due to the accumulation of incident cases but remained much lower among Arabs.

Conclusions: Understanding the factors underlying the differences in incidence and prevalence of IBD in the Jewish and Arab populations may shed light on the genetic and environmental factors associated with these diseases.

Background: Unilateral renal agenesis is a rare finding. There are no large-scale studies reporting this finding in early pregnancy.

Objectives: To evaluate the incidence of unilateral renal agenesis (URA) and of associated anomalies diagnosed by early prenatal trans-vaginal sonography.

Methods: We performed a retrospective chart review of all 59,382 trans-vaginal scans performed at 14–16 weeks gestation by a single operator at different clinics during the period 1994–2013.

Results: The incidence of URA was 1:1212 (49/59382 cases). Associated anomalies were diagnosed in 22 cases (45%). Renal anomalies were diagnosed in 22.4%. Extra-renal anomalies (with exclusion of a single umbilical artery or nuchal edema as isolated findings) were diagnosed in 24.5%. Ambiguous genitalia were diagnosed in 8.2%.

Conclusions: URA is a rare finding in early trans-vaginal sonography. Associated anomalies are very common and should be sought.

Background: Ga-prostate-specific membrane antigen positron emission tomography/computerized tomography (Ga-PSMA PET/CT) is part of the initial workup of patients with intermediate and high-risk prostate cancer provided by the Israeli national health services.

Objectives: To assess the incidence of metastatic spread in consecutive patients with newly diagnosed cancer, and the potential added value of Ga-PSMA PET/CT to the staging imaging algorithm.

Methods: Patients with newly diagnosed intermediate- and high-risk prostate cancer were referred for initial staging by Ga-PSMA PET/CT between May 2016 and April 2017. Blood prostate-specific antigen (PSA) levels, clinical history, imaging reports and histopathological reports (including Gleason scores) were obtained. Maximal standardized uptake values (SUVmax) were determined for the primary lesions detected within the prostate.

Results: The study included 137 consecutive patients with intermediate- and high-risk disease who underwent Ga-PSMA PET/CT staging. Of these, 75 had Ga-PSMA uptake in both prostate lobes, 57 had unilateral uptake, and 5 patients had no uptake. SUVmax in the primary tumor correlated significantly with PSA levels. Thirty-five patients had increased uptake compatible with metastatic disease involving lymph nodes, bone, and viscera. Twenty-seven patients had available bone scintigraphy results: 18 (69%) of their 26 bone metastases detected by Ga-PSMA PET/CT were missed on bone scintigraphy.

Conclusions: Ga-PSMA PET/CT shows promise as a sole whole-body imaging modality for assessing the presence of soft tissue and bone metastases in the setting of prostate cancer.

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.

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: Drooling is the unintentional loss of saliva from the mouth, usually caused by poor coordination of the swallowing mechanism. It is commonly seen in patients with chronic neurologic disorders, such as Parkinson's disease, amyotrophic lateral sclerosis (ALS), cerebral palsy, and stroke, as well as in patients with cognitive impairment and dementia.

Objectives: To evaluate the efficacy and safety of ultrasound-guided botulinum toxin injections into the parotid and submandibular salivary glands for the treatment of drooling.

Methods: We conducted a retrospective analysis of the medical records of 12 consecutive patients treated with botulinum toxin injections into the parotid and submandibular glands for the first time. The primary outcome variable was the subjective improvement of drooling on a 5-point scale. Secondary outcome variables were duration of the therapeutic effect, request to undergo additional treatment, and adverse events.

Results: Of 12 patients, 8 (67%) reported considerable improvement after treatment, 3 reported slight improvement, and 1 reported development of dry mouth. All patients stated that they felt the effects 1 week after the injections; the mean duration of the therapeutic effect was 4.5 months (range 3–9 months). One patient suffered from local hematoma and ecchymosis that did not require medical care. Another patient complained of difficulty swallowing, which did not require medical treatment and resolved spontaneously within 1 month.

Conclusions: Ultrasound-guided botulinum toxin injections into the parotid and submandibular glands seem to be a safe and effective therapy for the treatment of drooling. Further long-term prospective studies with varying doses are warranted.

Background: Dialysate purity contributes to the inflammatory response that afflicts hemodialysis patients.

Objectives: To compare the clinical and laboratory effects of using ultrapure water produced by a water treatment system including two reverse osmosis (RO) units in series, with a system that also includes an ultrapure filter (UPF).

Methods: We performed a retrospective study in 193 hemodialysis patients during two periods: period A (no UPF, 6 months) and period B (same patients, with addition of UPF, 18 months), and a historical cohort of patients treated in the same dialysis unit 2 years earlier, which served as a control group.

Results: Mean C-reactive protein, serum albumin and systolic blood pressure worsened in period B compared to period A and in the controls.

Conclusions: A double RO system to produce ultrapure water is not inferior to the use of ultrapure filters.

Background: Burn injury pathophysiology is characterized by severe catabolic state and poor glycemic control. A tight glycemic control protocol using insulin for burn victims has yielded inconsistent mortality and morbidity outcomes.

Objectives: To compare the effect of standard and tight glycemic control protocols on mortality and hypoglycemia events in critical care burn patients.

Methods: We conducted a case-control study of burn victims admitted to the burn intensive care unit between 2005 and 2011. Patients were assigned to either a standard or a tight glycemic control protocol.

Results: Of the 38 burn patients in the study, 28 were under a tight glycemic control protocol. No differences in glucose area-under-the-curve per day levels were observed between the groups (148.3 ± 16 vs. 157.8 ± 16 mg/dl in the standard and tight glycemic control protocol groups respectively, P < 0.12). The hypoglycemic event rate was higher in the tight glycemic control protocol group (46.4% vs. 0%, P < 0.008). No difference in mortality rate was noted (67.9% vs. 50%, P < 0.31). Mortality-independent risk factors found on multivariate analysis included total body surface area (adjusted hazard ratio [AHR] 1.039, 95% confidence interval  [95%CI] 1.02–1.06, P < 0.001), white blood cell count on admission (AHR 1.048, 95%CI 1.01–1.09, P < 0.02) and surgery during hospitalization (AHR 0.348, 95%CI 0.13–0.09, P < 0.03).

Conclusions: The tight glycemic control protocol in burn patients was associated with higher rates of hypoglycemic events, and no association was found with improved survival in the acute setting of burn trauma care.
