Background: Horse riding has become increasingly popular in recent years and is a common activity among children. As a result, pediatric horse-related injuries are frequently encountered in emergency departments.

Objectives: To examine the characteristics of horse-related injuries in the pediatric population.

Methods: We collected and analyzed the data on all pediatric horse-related injuries presented to a tertiary hospital, level one trauma center, during the years 2006–2016.

Results: A total of 53 children with horse-related injuries were documented. Forty-two patients were male (79%) and their mean age was 11.13 ± 4.72 years. The most common mechanism of injury was falling off a horse (31 patients, 58%) and the most common type of injury was skeletal (32 patients, 60%). Head injuries occurred in 16 patients (30%) and facial injuries in 12 (23%). The mean Injury Severity Score (ISS) was 10.5 ± 6.32, and 15 patients (28%) had severe trauma (ISS > 15). Twenty-nine patients (55%) required trauma team intervention, 12 (23%) were admitted to the intensive care unit, and 24 (45%) required surgery. The mean length of hospitalization was 4.3 ± 3.14 days.

Conclusions: Our study suggests that horse-related trauma may involve serious injuries and it exhibits typical injury patterns. Young boys are at highest risk. The potential severity of these injuries merits a thorough evaluation. We suggest that these injuries be triaged appropriately, preferably to a medical facility with proper trauma capabilities.

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: Rheumatic mitral stenosis (MS) is a relatively rare diagnosis in the developed countries and its treatment during pregnancy is challenging due to hemodynamic changes. With the demographic changes due to recent waves of immigration an increase in the prevalence of rheumatic heart disease is expected.

Objective: To evaluate maternal and neonatal complications in patients with mitral stenosis.

Methods: During the years 2006–2017, 22 women who underwent 31 pregnancies were followed at the Sheba Medical Center in Israel. We collected on regarding hemodynamic changes and their clinical course. MS was classified as mild, moderate, or severe according to mitral valve area by echocardiography. Maternal and fetal adverse events were evaluated according to severity of MS and compared by Poisson regression modeling.

Results: MS was severe in 7 pregnancies (22.6%), moderate in 9 (29%), and mild in 15 (48.4%). Twenty patients were managed conservatively and 2 underwent a successful percutaneous mitral balloon valvuloplasty (PBMVP) during pregnancy. All pregnancies ended with a liveborn neonate and with no maternal mortality. Peak and mean mitral pressure gradients increased during pregnancy from 13.3 ± 5.3 to 18.6 ± 5.1 mmHg and from 5.9 ± 2.3 to 9.6 ± 3.4 mmHg respectively (P < 0.05). Eight pregnancies (25.8%) were complicated by pulmonary congestion, 2/15 (13.3%) with mild MS, 2/9 (22.2%) with moderate, and 4/7 (57.1%) with severe MS. The adverse event rate was higher among patients with severe MS compared with moderate and mild MS [hazard ratio (HR) 3.15, 95% confidence interval (95%CA) 1.04–9.52 and HR 4.06, 95%CI 1.4–11.19 respectively, P < 0.05]. Nine of 31 deliveries were vaginal; 6 of 22 cesarean sections (27.3%) were performed for cardiac indications.

Conclusions: The number of total adverse events were higher among patients with severe MS. Patients with moderate and mild MS should be treated attentively, but good obstetric and maternal outcome can be expected.

Background: Contemporary data on clinical profiles and long-term outcomes of young adults with coronary artery disease (CAD) are limited.

Objectives: To determine the risk profile, presentation, and outcomes of young adults undergoing coronary angiography.

Methods: A retrospective analysis (2000–2017) of patients aged ≤ 35 years undergoing angiography for evaluation and/or treatment of CAD was conducted.

Results: Coronary angiography was performed in 108 patients (88% males): 67 acute coronary syndrome (ACS) and 41 non-ACS chest pain syndromes. Risk factors were similar: dyslipidemia (69%), positive family history (64%), smoking (61%), obesity (39%), hypertension (32%), and diabetes (22%). Eight of the ACS patients (12%) and 29 of the non-ACS (71%) had normal coronary arteries without subsequent cardiac events. Of the 71 with angiographic evidence of CAD, long-term outcomes (114 ± 60 months) were similar in ACS compared to non-ACS presentations: revascularization 41% vs. 58%, myocardial infarction 32% vs. 33%, and all-cause death 8.5% vs. 8.3%. Familial hypercholesterolemia (FH) was diagnosed in 25% of those with CAD, with higher rates of myocardial infarction (adjusted hazard ratio [HR] 2.62, 95% confidence interval [95%CI] 1.15–5.99) and revascularization (HR 4.30, 95%CI 2.01–9.18) during follow-up. Only 17% of patients with CAD attained a low-density lipoprotein cholesterol treatment goal < 70 mg/dl.

Conclusions: CAD in young adults is associated with marked burden of traditional risk factors and high rates of future adverse cardiac events, regardless of acuity of presentation, especially in patients with FH, emphasizing the importance of detecting cardiovascular risk factors and addressing atherosclerosis at young age.

Background: Recent studies have suggested that urgent cholecystectomy is the preferred treatment for acute cholecystitis. However, initial conservative treatment followed by delayed elective surgery is still common practice in many medical centers.

Objectives: To determine the effect of percutaneous cholecystostomy on surgical outcome in patients undergoing delayed elective cholecystectomy.

Methods: We conducted a retrospective analysis of all patients admitted to our medical center with acute cholecystitis who were treated by conservative treatment followed by delayed cholecystectomy between 2004 and 2013. Logistic regression was calculated to assess the association of percutaneous cholecystostomy with patient characteristics, planned surgical procedure, and the clinical and surgical outcomes.

Results: We identified 370 patients. Of these, 134 patients (36%) underwent cholecystostomy during the conservative treatment period. Patients who underwent cholecystostomy were older and at higher risk for surgery. Laparoscopic cholecystectomy was offered to 92% of all patients, yet assignment to the open surgical approach was more common in the cholecystostomy group (16% vs. 3%). Cholecystostomy was associated with significantly higher conversion rates to open approach (26% vs. 13%) but was not associated with longer operative time, hemorrhage, surgical infections, or bile duct or organ injuries.

Conclusions: Treatment with cholecystostomy is associated with higher conversion rates but does not include other major operative-related complications or poorer clinical outcome.

Background: Mortality and decrease in function after hip fracture are significantly related to patient factors including age, gender, co-morbidities, and mental status. Several studies demonstrated ethnic disparities in incidence, mortality, and functional outcome after hip fractures in the United States.

Objectives: To assess the relationship between ethnicity and hip fracture incidence and outcomes of mortality, functional change, and perioperative complications in the Israeli population.

Methods: We reviewed our institutional hip fracture registry for all patients from 2014–2015. Patients with incomplete data, < 60 years of age, or pathologic and periprosthetic fractures were excluded. Our study comprised 693 patients. Ethnicity was based on country of birth. Specifically, for those born in Israel, the nationality of either Jewish or Arab was further dichotomized. Perioperative complications, mortality, and mobility status at 1 year follow-up were recorded. The ethnicities of 27,130 patients admitted to the medicine and surgical wards during the same time interval served as a control group for the hip fracture cohort.

Results: Immigrants from Europe and America had the highest incidence of hip fractures. Fracture types varied in incidence in groups with 70% of extracapsular hip fractures occurring in Arabs and immigrants from Eastern countries, compared to 60% in immigrants from Western countries and the former Soviet Union. Mortality, perioperative complications, and mobility at 1 year were similar in all ethnic groups.

Conclusion: Our study demonstrated significant differences in incidence and fracture characteristic among ethnicities, but no difference in patient outcome. These findings differed from the available North American studies.

Background: Heart transplantation (HT) is the treatment of choice for patients with end-stage heart failure. The HT unit at the Sheba Medical Center is the largest of its kind in Israel.

Objectives: To evaluate the experience of HT at a single center, assess trends over 3 decades, and correlate with worldwide data.

Methods: Between 1990 and 2017, we reviewed all 285  adult HT patients. Patients were grouped by year of HT: 1990–1999 (decade 1), 2000–2009 (decade 2), and 2010–2017 (decade 3).

Results: The percentage of women undergoing HT has increased and etiology has shifted from ischemic to non-ischemic cardiomyopathy (10% vs. 25%, P = 0.033; 70% vs. 40% ischemic, for decades 1 vs. 3, respectively). Implantation of left ventricular assist device as a bridge to HT has increased. Metabolic profile has improved over the years with lower low-density lipoprotein, diabetes, and hypertension after HT (101 mg/dl, 27%, and 41% at decade 3, respectively). There has been a prominent change in immunosuppressive treatments, currently more than 90% are treated with tacrolimus, compared with 2.7% and 30.9% in decades 1 and 2, respectively (P < 0.001). Cardiac allograft vasculopathy (CAV) rates have declined significantly (47% vs. 17.5% for decades 1 and 2, P < 0.001) as have the combined endpoint of CAV/death. Similarly, the current incidence of acute rejections is significantly lower.

Conclusions: Our analysis of over 25 years of a single-center experience with HT shows encouraging improved results, which are in line with worldwide standards and experience.

Background: Ptyalism gravidarum (PG) is a condition of hypersalivation that affects pregnant women early in gestation. Symptoms include massive saliva volumes (up to 2 liters per day), swollen salivary glands, sleep deprivation, significant emotional distress, and social difficulties.

Objectives: To examine maternal and fetal characteristics and pregnancy outcomes of patients with PG.

Methods: Patients diagnosed with PG in our clinic during the years 2001–2016 were identified and contacted. Demographic data were extracted from patient charts and clinical and outcome data was collected via telephone interviews.

Results: The incidence of PG was 1/963 (0.09%) in our sample. Eleven out of 22 women (40%) with PG were also diagnosed with hyperemesis gravidarum. Fetal gender did not increase the risk. Of the mothers presenting with PG, 37% had a positive family history for this condition. There was no associated increase in the rate of fetal or maternal complications. Two women reported a resolution of the symptoms immediately following hypnosis with acupuncture treatment.

Conclusions: Although PG represents an unpleasant mental and physical condition, it does not pose any specific risk to the health of the mother or increase adverse perinatal outcomes for the fetus. Alternative medicine could play a role in the treatment of PG.

Background: Cardiac damage caused by oncological therapy may manifest early or many years after the exposure.

Objectives: To determine the differences between sub-acute and late-onset cardiotoxicity in left ventricular ejection fraction (LVEF) recovery as well as long-term prognosis.

Methods: We studied 91 patients diagnosed with impaired systolic function and previous exposure to oncological therapy. The study population was divided according to sub-acute (from 2 weeks to ≤ 1 year) and late-onset (> 1 year) presentation cardiotoxicity. Recovery of LVEF of at least 50% was defined as the primary end point and total mortality was the secondary end point.

Results: Fifty-three (58%) patients were classified as sub-acute, while 38 (42%) were defined as late-onset cardiotoxicity. Baseline clinical characteristics were similar in the two groups. The mean LVEF at presentation was significantly lower among patients in the late-onset vs. sub-acute group (28% vs. 37%, respectively, P < 0.001). Independent predictors of LVEF recovery were trastuzumab therapy and a higher baseline LVEF. Although long-term mortality rates were similar in the groups with sub-acute and late-onset cardiotoxicity, improvement of LVEF was independently associated with reduced mortality.

Conclusions: Our findings suggest that early detection and treatment of oncological cardiotoxicity play an important role in LVEF recovery and long-term prognosis.

Background: Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Objectives: To evaluate our experience with aortic valve repair (AVr) in patients with bicuspid or unicuspid aortic valves.

Methods: Eighty patients with BAV or unicuspid aortic valve (UAV) underwent AVr. Mean patient age was 42 ± 14 years and 94% were male. Surgical technique included: aortic root replacement with or without cusp repair in 43 patients (53%), replacement of the ascending aorta at the height of the sino-tubular junction with or without cusp repair in 15 patients (19%), and isolated cusp repair in 22 patients (28%).

Results: The anatomical structure of the aortic valve was bicuspid in 68 (85%) and unicuspid in 12 patients (15%). Survival rate was 100% at 5 years of follow-up. Eleven patients (13.7%) underwent reoperation, 8 of whom presented with recurrent symptomatic aortic insufficiency (AI). Late echocardiography in the remaining 69 patients revealed mild AI in 63 patients, moderate recurrent AI in 4, and severe recurrent AI in 2. Relief from recurrent severe AI or reoperations was significantly lower in patients who underwent cusp repair compared with those who did not (P = 0.05). Furthermore, the use of pericardial patch augmentation for the repair was a predictor for recurrence (P = 0.05).

Conclusions: AVr in patients with BAV or UAV is a safe procedure with low morbidity and mortality rates. The use of a pericardial patch augmentation was associated with higher repair failure.

Background: Supracondylar humerus fractures are the most common elbow fractures in the pediatric population.

Objectives: To evaluate the outcomes of French's corrective osteotomy for correction of post-traumatic cubitus varus deformity in children.

Method: We conducted a retrospective review of medical charts of all patients who had undergone French's corrective osteotomy in our institution from 1998 to 2012. We recorded range of motion, cosmetic deformity, carrying angle, lateral cortex prominence index, hyperextension, and lateral cortex step before and after the surgery.

Results: Seven patients were enrolled the study. Average follow-up time was 4.6 years (range 2–9 years). An average of 18.3º of limited flexion (range 5º–35º) compared to the healthy elbow was recorded in three patients. Lateral condylar prominence was recorded in one patient. The average preoperative carrying angle was -20.5º (range -15º–30º) and postoperative angle was 9.6º (range 7º–13º). In comparison, the average carrying angle in the healthy elbow was 8.5º (range 4º–13º). No lateral cortex prominence was recorded. An average of 27.5º (range 15º–35º) of hyperextension of the distal fragment was recorded immediately postoperatively in four patients; however, during postoperative follow-up, the hyperextension was corrected spontaneously in all patients.

Conclusions: As described by French, osteotomy has the ability to correct the varus deformity only in the coronal plane. However, our research supports the assumption that hyperextension in the sagittal plane might be corrected spontaneously.

Background: One-stage direct-to-implant post-mastectomy breast reconstruction has been gaining popularity over the traditional two-stage/tissue-expander approach.

Objectives: To evaluate the outcome of the two post-mastectomy breast reconstruction procedures in terms of patient satisfaction.

Methods: Clinical data were collected by file review for patients who underwent mastectomy with immediate breast reconstruction at two tertiary medical centers in 2010–2013. Patients were asked to complete the BREAST-Q instrument, sent to them by post with a self-addressed, stamped, return envelope. Scores were compared by type of reconstruction performed.

Results: Of the 92 patients who received the questionnaire, 59 responded: 39 had one-stage breast reconstruction and 20 underwent two-stage reconstruction. The two-stage reconstruction group was significantly older, had more background diseases, and were followed for a longer period. The one-stage reconstruction group had a higher proportion of BRCA mutation carriers. There was no significant between-group difference in postoperative complications. Mean BREAST-Q scores were similar in the two groups for all dimensions except satisfaction with information, which was higher in the patients after one-stage reconstruction. Women with more background diseases had better sexual well-being, and married women had better psychological well-being. Breast satisfaction was lower among patients treated with radiation and higher among patients with bilateral reconstruction; the latter subgroup also had higher physical well-being. Complications did not affect satisfaction.

Conclusions: Patients were equally satisfied with the outcome of one- and two-stage breast reconstruction. The choice of technique should be made on a case-by-case basis. Cost analyses are needed to construct a decision-making algorithm.

Background: Gender-related differences (GRD) exist in the outcome of patients with cardiac resynchronization therapy (CRT).

Objectives: To assess GRD in patients who underwent CRT.

Methods: A retrospective cohort of 178 patients who were implanted with a CRT in a tertiary center 2005–2009 was analyzed. Primary outcome was 1 year mortality. Secondary endpoints were readmission and complication rates.

Results: No statistically significant difference was found in 1 year mortality rates (14.6% males vs. 11.8% females, P = 0.7) or in readmission rate (50.7% vs. 41.2%, P = 0.3). The complication rate was only numerically higher in women (14.7% vs. 5.6%, P = 0.09). Men more often had CRT-defibrillator (CRT-D) implants (63.2% vs. 35.3%, P = 0.003) and had a higher rate of ischemic cardiomyopathy (79.2% vs. 38.2%, P < 0.001). There was a trend to higher incidence of ventricular fibrillation/ventricular tachycardia in men before CRT implantation (29.9% vs. 14.7%, P = 0.07%). A higher proportion of men upgraded from implantable cardioverter defibrillator (ICD) to CRT-D, 20.8% vs. 8.8%, P = 0.047. On multivariate model, chronic renal failure was an independent predictor of 1 year mortality (hazard ratio [HR] 3.6; 95% confidence interval [95%CI] 1.4–9.5), CRT-D had a protective effect compared to CRT-pacemaker (HR 0.3, 95%CI 0.12–0.81).

Conclusions: No GRD was found in 1 year mortality or readmission rates in patients treated with CRT. There was a trend toward a higher complication rate in females. Men were implanted more often with CRT-D and more frequently underwent upgrading of ICD to CRT-D.

Background: Management of patients with hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) is evolving worldwide. Evaluating the Israeli experience may provide valuable insights.

Objectives: To compare demographics and icatibant treatment patterns and outcomes in patients with C1-INH-HAE enrolled in the Icatibant Outcome Survey (IOS) in Israel with those in other countries.

Methods: The IOS is an ongoing observational study that prospectively monitors real-world icatibant safety/tolerability and treatment outcomes.

Results: By July 2016, 58 patients from Israel and 594 patients from other countries were enrolled. Median age at diagnosis (16.7 vs. 21.3 years, P = 0.036) and median delay between symptom onset and diagnosis (0.8 vs. 6.6 years, P = 0.025) were lower in Israel compared with other countries, respectively. Differences in attack severity were not significant (P = 0.156); however, during follow-up, Israeli patients were less likely to miss > 7 days of work/school due to C1-INH-HAE-related complications (P = 0.007). A trend was also shown in Israel for earlier time to treatment (median 0.5 vs. 1.3 hours, P = 0.076), attack duration was shorter (median 5.0 vs. 9.0 hours, P = 0.026), and patients more often self-administered icatibant (97.2% vs. 87.5%, P = 0.003), respectively. However, Israeli patients were less likely to treat attacks (P = 0.036). Whereas patients in Israel reported exclusive use of danazol for long-term prophylaxis, those in other countries used various agents, including C1-INH.

Conclusions: Recognition of C1-INH-HAE and timeliness of icatibant treatment appear more favorable, and attack duration shorter, in Israel compared with other countries.
