Background: Statin-induced myalgia is defined as muscle pain without elevation of serum creatine phosphokinase levels and is a well-known complaint among statin users. Chronic pain syndromes affect a high percentage of the population. These pain syndromes may confound the reports of statin-induced myalgia.

Objectives: To compare the occurrence of chronic pain among patients on statin therapy who developed myalgia with those who did not.

Methods: This study included 112 statin-treated patients, who were followed at the lipid center at Sheba Medical Center. Fifty-six patients had a diagnosis of statin-associated muscle symptoms (SAMS) and 56 did not. Verified questionnaires were used to assess the diagnoses of fibromyalgia, pain intensity, functional impairment, anxiety, and depression in the study population.

Results: Patients with statin myalgia were more likely to fulfil the diagnostic criteria for fibromyalgia than patients without statin myalgia (11 [19.6%] vs. 0, respectively). Patients in the SAMS group exhibited higher levels of anxiety and depression compared with the control group. Female sex, higher scores on the Brief Pain Inventory pain intensity scale, and a Hamilton rating scale level indicative of an anxiety disorder were found to be significant predictors for fibromyalgia in patients presenting with statin myalgia.

Conclusions: A significant percentage of patients diagnosed with statin myalgia fulfilled the diagnostic criteria for fibromyalgia depression or anxiety disorder. Detection of these patients and treatment of their primary pain disorders or psychiatric illnesses has the potential to prevent unnecessary cessation of effective statin therapy.

Backgrounds: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression.

Objectives: To evaluate the association between BD and depression, adjusting for established risk factors for depression.

Methods: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex.

Results: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37–2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39–2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18–39 years of age), low and high socioeconomical status, and non-smokers.

Conclusions: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Background: Fibromyalgia syndrome (FMS) is characterized by widespread musculoskeletal pain and tenderness with associated neuropsychological symptoms such as fatigue, unrefreshing sleep, cognitive dysfunction, anxiety, and depression. Osteoporosis is defined as a reduction of bone density. Previous studies to determine an association of FMS with osteoporosis showed mixed results, partially due to small sample sizes and lack of statistical power.

Objectives: To evaluate the association of FMS with osteoporosis.

Methods: We conducted a case-control study utilizing the database from Israel’s largest health maintenance organization. FMS patients were compared to age- and sex-matched controls. Data were analyzed using chi-square and t-tests. Multivariable logistic regression models assessed the association between osteoporosis and FMS. Spearman’s rho test was used for correlation.

Results: We utilized data from 14,296 FMS patients and 71,324 age- and sex-matched controls. Spearman's rho test showed a significant correlation between FMS and osteoporosis (correlation coefficient 0.55, P < 0.001). A logistic regression for osteoporosis showed an odds ratio [OR] of 1.94 (95% confidence interval [95%CI] 1.83–2.06, P < 0.001) for FMS compared to controls and found higher body mass index to be slight protective (OR 0.926, 95%CI 0.92–0.93, P < 0.001).

Conclusions: There is a significant correlation between FMS and osteoporosis. Early detection of predisposing factors for osteoporosis in FMS patients and implementation of suitable treatments and prevention measures (such as dietary supplements, resistance or weight bearing exercise, and bone-mineral enhancing pharmacological therapy) may reduce both occurrence rate and severity of osteoporosis and its complications, such as fractures.

Background: Statins have anti-inflammatory effects that are independent of their lipid-lowering activity.

Objectives: To examine whether prior statins therapy affects the clinical course of the first episode of acute idiopathic pericarditis (AIP) as the 1-year recurrence and length of hospitalization (LOH).

Methods: This retrospective study included 148 subjects with first episode AIP admitted between the years 2015 and 2019. Data were collected from two hospitals in Northern Israel. We divided the patients in into two groups: 117 those without statins use and 31 those with prior statins use. We compared age, sex, co-morbidities, drugs, laboratory data, 1-year recurrence, and LOH.

Results: The mean age of participants was 43.1 ± 19.4 years. Comparisons between subjects without statins and with prior statins use were made according to age (37.5 ± 16.7 years vs. 64.4 ± 12.7 years, P < 0.01), C-reactive protein (50 ± 40 vs. 48 ± 35 mg/dl, P = 0.9), LOH (5.4 ± 2.85 vs. 8.03 ± 4.92 days, P < 0.01), 1-year recurrence of pericarditis (23 vs. 6 cases, P = 0.95), respectively. Multivariate logistic regression analysis revealed that 1-year recurrence (odds ratio [OR] 0.8, 95% confidence interval [95%CI 0 0.6–1.1, P = 0.41), was not associated with prior statin use, while LOH (OR 2.56, 95%CI 2.08–2.75, P = 0.01) was prolonged with prior statins use in patients with first episode of AID.

Conclusions: Prior statins use in patients with the first episode of AIP did not reduce the 1-year recurrence of pericarditis and prolong the LOH.

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia. Previous studies showed that rhythm and rate control strategies are associated with similar rates of mortality and serious morbidity. Beta blockers (BB) and calcium channel blockers (CCB) are commonly used and the selection between these two medications depends on personal preference.

Objectives: To compare real-time capability of BB and CCB for the treatment of rapid AF and to estimate their efficacy in reducing hospitalization duration.

Methods: We conducted a retrospective cohort study of 306 patients hospitalized at Soroka Hospital during a 5-year period with new onset AF who were treated by a rate control strategy.

Results: A significant difference between the two groups regarding the time (in hours) until reaching a target heart rate below 100 beats/min was observed. BB were found to decrease the heart rate after 5 hours (range 4–14) vs. 8 hours (range 4–18) for CCB (P = 0.009). Patients diagnosed with new-onset AF exhibited shorter duration of hospitalization after therapy with BB compared to CCB (median 72 vs. 96 hours, P = 0.012) in the subgroup of patients discharged with persistent AF. There was no significant difference between CCB and BB regarding the duration of hospitalization (P = 0.4) in the total patient population.

Conclusions: BB therapy is more potent for rapid reduction of the heart rate compared to CCB and demonstrated better efficiency in shortening the duration of hospitalization in a subgroup of patients. This finding should be reevaluated in subsequent research.

Mesenteric venous thrombosis (MVT) refers to acute, subacute, or chronic thrombosis and occlusion of the mesenteric veins. MVT is an uncommon disorder, with an estimated incidence of is 2.7 per 100,000 patient-years. It accounts for 1 in 5000 to 15,000 inpatient admissions [1,2].

Background: Hospitalization is an inherently serious event in the oldest-old, as the risk of complications associated with it increases exponentially with age and can lead to death. Despite the size of the problem, few studies have been dedicated to determining mortality predictors among hospitalized older patients, particularly among the oldest-old.

Objectives: To examine in-hospital mortality predictors in the oldest-old adults hospitalized in an acute geriatric ward.

Methods: We retrospectively surveyed electronic hospital health records of 977 elderly patients, aged ³ 90 years, admitted between January 2007 and December 2010 from the emergency department to the acute geriatrics department. We compared the characteristics of the patients who survived to those who died during the hospital stay.

Results: The patients mean age was 93.4 years. In-hospital mortality rate was about 11.6%. Mortality predictors were female sex, on-admission pneumonia, co-morbid congestive heart failure and cerebrovascular accident, high troponin I levels, lower levels of albumin, and higher level of urea (P = 0.032, P < 0.0001, P = 0.0015, P = 0.0049, P = 0.0503, P < 0.0001 and P < 0.0001, respectively). Consumption of ³ 5 drugs and the number of hospitalizations in the last year were inversely associated with death (P = 0.0145 and P < 0.0001, respectively).

Conclusions: Careful evaluation of mortality predictors might be useful for therapeutic planning and identification of potential inpatients for specific interventions. Awareness of in-hospital mortality predictors might contribute to reducing in-hospital death.

Background: The growing popularity of trampoline jumping in the past years has led to an increase in trampoline-related injuries. The risk is particularly high in large trampoline parks, which are attended by many individuals of various sizes and ages.

Objective: To describe a tertiary pediatric center experience in Israel.

Methods: The database of a tertiary pediatric medical center was retrospectively reviewed for all trampoline-associated admissions to the emergency department in 2015–2018. Data were collected on patient demographics and injury characteristics with an emphasis on type and venue.

Results: Of the 23,248 admissions for orthopedic trauma during the period, 244 children were admitted for 246 trampoline-related injuries. Injuries involved the lower limb in 130 children (53%), upper limb in 87 (36%), spine in 20 (8%), and other sites in 9 (3%). Almost half of the injuries (113/246, 46%) were fractures, 27% required either closed or open reduction in the operating room. Large trampoline centers were responsible for half of the cases.

Conclusions: Trampoline injuries accounted for 1.05% of all emergency department admissions at a tertiary pediatric hospital in 2015–2018. Nearly half of the trampoline-related injuries were fractures. Large trampoline centers pose a potential risk for more serious injuries. We raise awareness of the risks of trampoline jumping, considering increasing popularity of trampoline parks, and encourage the authorities to implement safety regulations.

Background: Little is known about the success of multidisciplinary thyroid eye disease (TED) clinic.

Objectives: To present the characteristics, treatments, and outcomes of patients treated in a multidisciplinary TED clinic.

Methods: A medical record review of all patients who attended a TED clinic was performed. Data included demographics, medical history, laboratory tests, visual function tests, ocular examinations, clinical activity score (CAS), and assessment of quality-of-life (QOL).

Results: Clinic visits included 132 patients seen during 385 appointments at a TED clinic (mean 12 appointments per patient). Management of TED included medical treatments for 48 patients (36.3%) and surgical treatment for 56 (42.4%). There was a positive significant correlation between the CAS and thyroid-stimulating immunoglobulin (TSI) activity at the first visit and at the last follow-up visit (P < 0.01 and P < 0.02, respectively). However, no correlation was found between the CAS and the thyroid-stimulating hormone levels or between the free triiodothyronine (fT3) and fT4 levels at the first or last visit. There was a significant negative correlation between the CAS and color vision (-0.347, P < 0.01, Pearson correlation) at the first visit, but not between the CAS and visual acuity and visual field at either the first or last visit. Changes in the QOL and the CAS scores were significantly negatively correlated (-0.240, P < 0.01).

Conclusions: Treatment and management decisions for TED should be based on multiple parameters including clinical examinations by ophthalmologists and endocrinologists, laboratory tests, and CAS and QOL scores.

Background: Coronavirus disease 2019 (COVID-19) led to two nationwide lockdowns in Israel, reducing both supply and demand for medical services in the Israel Defense Force (IDF). IDF soldiers serve on bases within Israel, and most of them return home at the end of the day, similar to other armies in the world.

Objectives: To analyze the health services provided by the IDF with regard to policy changes during lockdowns.

Methods: We compared medical encounters between different services provided by the IDF Medical Corps. We related them to specific time periods: pre-first lockdown, first lockdown (and corresponding timeframes of the previous 3 years), between lockdowns, second lockdown, and post-second lockdown.

Results: Compared to past periods, we found a similar reduction of 27–30% in primary care medical encounter rates during the two lockdowns: 42–43% in sick days and 50–54% in referrals to the emergency department. Referral rates to all specialist medical encounters and elective surgeries decreased significantly during the first lockdown period and increased 1.2–3.5 times during the second lockdown.

Conclusions: A continuance of the shift to telehealth is required to withstand a future lockdown, with a full supply of secondary medical services attuned to core medical issues relevant for combat personnel. A liberal sick leave policy is required to eliminate unnecessary in-person visits, thus reducing the risk of infection.

Background: Chest trauma is among the most common types of trauma, corresponding to 10% of trauma patients admitted to hospitals. In the military setting, thoracic trauma was reported as a significant cause of death. With well-timed treatment, chest trauma is regarded as survivable. Emergency thoracotomy (ET) is considered when the patient with trauma to the chest needs immediate resuscitation. Survival rate is reported as low as 1% in some reports and 20% in others. The survival rate depends on injury mechanism, protocols for intervention, and other decompressive procedures.

Objectives: To determine parameters that may impact survival of ET.

Methods: We conducted a retrospective cohort study to compare prehospital and in-hospital data regarding ET in the emergency department (ED) versus the operating room (OR).

Results: Between 2009 and 2017, 6532 casualties presented to the ED; 1125 with trauma to the chest. Fifty-four of those with chest trauma underwent ET in the hospital (4.8%), 22 (41%) in the ED, and 32 (59%) in the OR. The overall mortality of the ET subgroup was 48%. With regard to thoracotomies, 19/22 of patients (86%) who underwent ET in the ED died compared to 2/28 in the OR (13%).

Conclusions: Utilizing ET after chest trauma with appropriate clinical indications, well-trained personnel, and prompt transportation poses a significant challenge, but may be associated with better survival than that reported previously with military casualties. Adoption of indications and timed allocation to the OR may improve outcomes with chest trauma casualties.

Background: Pain control in trauma is an integral part of treatment in combat casualty care. More soldiers injured on the battlefield need analgesics for pain than life-saving interventions (LSIs). Early treatment of pain improves outcomes after injury, while inadequate treatment leads to higher rates of post-traumatic stress disorder (PTSD).

Objective: To describe the experience of the Israel Defense Forces (IDF) Medical Corps with prehospital use of analgesia.

Methods: All cases documented in the IDF-Trauma Registry between January 1997 and December 2019 were examined. Data collection included analgesia administered, mechanism of injury, wound distribution, and life-saving interventions performed.

Results: Of 16,117 patients, 1807 (11.2%) had at least one documented analgesia. Demographics included 91.2% male; median age 21 years. Leading mechanism of injury was penetrating (52.9%). Of injured body regions reported, 46.2% were lower extremity wounds. Most common types of analgesics were morphine (57.2%) and fentanyl (27%). Over the two decades of the study period, types of analgesics given by providers at point of injury (POI) had changed. Fentanyl was introduced in 2013, and by 2019 was given to 39% of patients. Another change was an increase of casualties receiving analgesia from 5–10% until 2010 to 34% by 2019. A total of 824 LSIs were performed on 556 patients (30.8%) receiving analgesia and no adverse events were found in any of the casualties.

Conclusions: Most casualties at POI did not receive any analgesics. The most common analgesics administered were opioids. Over time analgesic administration has gained acceptance and become more commonplace on the battlefield.

Background: Freeze dried plasma (FDP) is a commonly used replacement fluid in the prehospital setting when blood products are unavailable. It is normally administered via a peripheral intravenous (PIV) line. However, in severe casualties, when establishing a PIV is difficult, administration via intraosseous vascular access is a practical alternative, particularly under field conditions.

Objectives: To evaluate the indications and success rate of intraosseous administration of FDP in casualties treated by the Israel Defense Forces (IDF).

Methods: A retrospective analysis of data from the IDF-Trauma Registry was conducted. It included all casualties treated with FDP via intraosseous from 2013 to 2019 with additional data on the technical aspects of deployment collected from the caregivers of each case.

Results: Of 7223 casualties treated during the study period, intravascular access was attempted in 1744; intraosseous in 87 of those. FDP via intraosseous was attempted in 15 (0.86% of all casualties requiring intravascular access). The complication rate was 73% (11/15 of casualties). Complications were more frequent when the event included multiple casualties or when the injury included multiple organs. Of the 11 failed attempts, 5 were reported as due to slow flow of the FDP through the intraosseous apparatus. Complications in the remaining six were associated with deployment of the intraosseous device.

Conclusions: Administration of FDP via intraosseous access in the field requires a high skill level.
