Malignant melanoma is one of the most extensively studied diseases in the last few decades. The outcome of these studies and the treatment changes that followed have dramatically altered the landscape of not only melanoma therapy, but all solid tumors. In this review we presented the recent advances of surgical and adjuvant management of patients with cutaneous malignant melanoma. This review focuses on stage III melanoma since this stage of disease requires surgical treatment as well as adjuvant therapy

Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing. Once found, fetal CAVB is almost always irreversible, despite aggressive immunotherapy. This poor outcome prompted some research groups to address this situation. All groups followed anti-Ro/SS-A seropositive pregnancies on a weekly basis during the second trimester of pregnancy and tried to detect first degree atrioventricular block (AVB) using accurate echocardiographic tools, assuming they may characterize the initiation of the immune damage to the A-V conduction system, at which point the process might still be reversible. Some of the groups treated fetuses with first degree AVB with maternal oral fluorinated steroids. We summarized the results of all groups, including our group. We describe a case of a fetus that developed CAVB 6 days after normal sinus rhythm (NSR), who under aggressive dexamethasone therapy gradually reverted to NSR. This fetus had a previous sibling with CAVB. We assumed the immune damage to the conduction system in this small group of fetuses with a previous CAVB sibling may have occurred more quickly than usual. We therefore recommend a twice-weekly follow-up with these fetuses

Background: Patients with severe chronic obstructive pulmonary disease (COPD) experience frequent exacerbations and need to be hospitalized, resulting in an economic and social burden. Although data exist regarding reasons of frequent hospitalizations, there is no data available about the impact on the length of stay (LOS).

Objectives: To characterize the causes of prolonged hospitalizations in COPD patients.

Methods: A retrospective study was conducted of patients who were diagnosed and treated in the pulmonary department for severe COPD exacerbations. All patient demographic data and medical history were collected. Data regarding the disease severity were also collected (including Global Initiative for Obstructive Lung Disease [GOLD] criteria, pulmonologist follow-up, prior hospitalizations, and LOS).

Results: The study comprised 200 patients, average age 69.5 ± 10.8 years, 61% males. Of these patients, 89 (45%) were hospitalized for up to 4 days, 111 (55%) for 5 days or more, and 34 (17%) for more than 7 days. Single patients had longer LOS compared with married patients (48% vs. 34%, P = 0.044). Multivariate analysis showed that the number of prior hospital admissions in the last year was a predictor of LOS (P = 0.038, odds ratio [OR] = 0.807, 95% confidence interval [95%CI] = 0.659–0.988), as well as the use of non-invasive respiratory support by bilevel positive airway pressure (BiPAP) during the hospitalization (P = 0.024, OR = 4.662, 95%CI = 1.229–17.681).

Conclusions: Fewer previous hospitalizations due to COPD exacerbations and the need for non-invasive respiratory support by BiPAP were found as predictors of longer LOS.

Background: The reported mortality rates of patients with polymyositis and dermatomyositis are highly variable worldwide. The excess mortality of patients with polymyositis/dermatomyositis has not been evaluated in an Israeli population.

Objectives: To investigate the overall mortality in a large and well-established cohort of patients with polymyositis/dermatomyositis as compared to the mortality expected in the matched general population in a tertiary medical center.

Methods: In this retrospective cohort study, the mortality of 166 patients with polymyositis/dermatomyositis was compared to age- and sex-matched control subjects in the general population. All-cause standardized mortality ratios (SMRs) were estimated.

Results: Overall, 47 (28.3%) deaths were observed among patients with polymyositis/dermatomyositis during a mean follow-up period of 5.8 ± 4.8 years, which was 7 times higher than in the control group (SMR 7.4, 95% confidence interval [95%CI] 5.5–9.8). The SMRs were comparable in patents with polymyositis (7.7, 95%CI 4.8–12.3) and dermatomyositis (7.2, 95%CI 5.0–10.3). The 1-, 5-, 10-, and 15-year overall survival rates were 90.0%, 82.8%, 51.5%, and 26.1%, respectively, in patients with polymyositis, and 80.3%, 59.6%, 40.0%, and 17.1%, respectively, in patients with dermatomyositis.

Conclusions: The overall mortality among Israeli patients with polymyositis/dermatomyositis is 7.4 times greater than for the general population. Although long-term mortality was comparable between patients with dermatomyositis and polymyositis, patients in the former group died at a notably earlier stage.

Background: In Israel, critically ill patients are ventilated and managed in intensive care units or general wards.

Objectives: To compare the mortality rates and long-term cognitive and functional outcomes of ventilated patients who underwent tracheostomy insertion in the Medical ICU (MICU) versus those cared for in the in-patient wards.

Methods: The study comprised 170 patients who underwent percutaneous dilatational tracheostomy (PDT) over an 18-month period in the MICU (n=102) and in in-patient wards (internal medicine and neurology) (n=68). Telephone interviews were conducted with living patients and/or their relatives at least 6 months after discharge from the hospital.

Results: Ward patients were 10 years older than ICU patients undergoing PDT (P = 0.003). The length of stay (LOS) in the wards was longer than in the ICU (P < 0.001), whereas the total LOS in the hospital was similar (P = 0.43). ICU mortality was lower than in the wards (P = 0.001) but hospital mortality was comparable between the two groups (P = 0.17). At 6 months follow-up more ICU patients were fully conscious, weaned from ventilation, and decannulated. More patients in the ICU group were at home and were independent or had mildly impaired activities of daily living. More patients in the ward group were residing in long-term care facilities with functional limitations.

Conclusions: MICU patients who undergo tracheostomy may have a good long-term functional and cognitive outcome. More studies are needed to further assess long-term outcomes in these patients.

Background: The safe completion of cholecystectomy is dependent on proper identification and secure closure of the cystic duct. Effecting this closure poses a great challenge when inflammatory changes obscure the anatomy. Subtotal cholecystectomy allows for near complete removal of the gallbladder and complete evacuation of the stones while avoiding dissection in the hazardous area.

Objectives: To describe experience with laparoscopic subtotal cholecystectomy.

Methods: Subtotal cholecystectomy was performed when the critical view of safety could not be achieved. Surgical technique was similar in all cases and included opening the Hartmann’s pouch, removing stones obstructing the gallbladder outlet, and identifying the opening of the cystic duct, as well as circumferential transection of the gallbladder neck, closure of the gallbladder stump, and excision of the gallbladder fundus. Data retrieved from patient charts included demographics, pre-operative history, operative and postoperative course, and late complications. No bile duct injuries were observed in this series.

Results: A total of 53 patients underwent laparoscopic subtotal cholecystectomy (2010–2018). Ten patients were operated during the acute course of the disease and 43 electively. Acute cholecystitis was the leading cause for gallbladder removal. Cholecystostomy tube was placed in 18 patients during acute hospitalization. The gallbladder remnant was closed and a drain was placed in most patients. Of the 53 patients, 42 had an uneventful postoperative course.

Conclusions: Laparoscopic subtotal cholecystectomy is an effective surgical technique to avoid bile duct injury when the cystic duct cannot safely be identified. Subtotal cholecystectomy has acceptable morbidity and obviates the need for conversion in these difficult cases.

Background: In 2006, the International Society for Heart and Lung Transplantation amended the guidelines for the upper age limit of heart transplantation (HTx) from 55 years to 70 years and older for carefully selected patients. However, the relation of age to outcomes following of HTx has not been well studied.

Objectives: To investigate the impact of recipient age on the occurrence of rejections, vasculopathy, and mortality after HTx.

Methods: Study population comprised all consecutive 291 patients who underwent HTx between 1991–2016 and were followed at our center. Patients were categorized by age tertiles: < 46 years (mean 31.4 ± 11.7, range 16–45, n=90), 46–57 years (mean 51.4 ± 3.2, range 46–56, n=92), and ≥ 57 years (mean 61.6 ± 3.4, range 57–73, n=109).

Results: Patients aged ≥ 57 years were more often males and had more pre-HTx co-morbidities including hypertension, diabetes, dyslipidemia, and history of smoking (P < 0.05) compared to the younger age groups. Kaplan-Meier analysis by age tertiles showed the rates of major rejections and vasculopathy at 15 years were similar among the three age groups. Mortality rates at 15 years were directly related to the age groups (39%, 52%, 62% log-rank, P = 0.01). However, the association between age and mortality was no longer statistically significant after multivariate analysis (hazard ratio 1.01, 95% confidence interval 1.00–1.03).

Conclusions: In a contemporary cohort of patients undergoing HTx, recipient age does not significantly impact the risk of major rejections, vasculopathy, and long-term mortality.

Background: Progress in the treatment of breast cancer has led to substantial improvement in survival, but at the cost of increased side effects, with cardiotoxicity being the most significant one. The commonly used definition is cancer therapeutics-related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction reduction of > 10%, to a value below 53%. Recent studies have implied that the incidence of CTRCD among patients with breast cancer is decreasing due to lower doses of anthracyclines and low association to trastuzumab and pertuzumab treatment.

Objectives: To evaluate the prevalence of CTRCD among patients with active breast cancer and to identify significant associates for its development.

Methods: Data were collected as part of the Israel Cardio-Oncology Registry, which enrolls all patients who are evaluated at the cardio-oncology clinic at our institution. Patients were divided to two groups: CTRCD and no-CTRCD.

Results: Among 103 consecutive patients, five (5%) developed CTRCD. There were no significant differences in the baseline cardiac risk factors between the groups. Significant correlations of CTRCD included treatment with trastuzumab (P = 0.001) or pertuzumab (P < 0.001), lower baseline global longitudinal strain (GLS) (P = 0.016), increased left ventricular end systolic diameter (P < 0.001), and lower e’ septal (P < 0.001).

Conclusions: CTRCD is an important concern among patients with active breast cancer, regardless of baseline risk factors, and is associated with trastuzumab and pertuzumab treatment. Early GLS evaluation may contribute to risk stratification and allow deployment of cardioprotective treatment

Background: The incidence of gestational diabetes mellitus (GDM) is increasing in parallel to the worldwide obesity and type 2 diabetes pandemic. Both GDM and pre-gestational diabetes mellitus (PGDM) are associated with short- and long-term consequences in the offspring. There are few recent studies addressing outcomes of newborns born to women diagnosed with GDM and PGDM in Israel.

Objectives: To assess perinatal complications in offspring of women with GDM and PGDM.

Methods: The authors conducted a single-center retrospective case-control study of outcomes of all newborns whose mothers had been diagnosed with diabetes in pregnancy compared to randomly assigned controls born on the same date, whose mothers had no diabetes.

Results: In the study period 2015–2017, 526 mothers diagnosed with GDM or PGDM and their newborn infants were identified. The authors randomly assigned 526 control infants. The rate of women with diabetes in pregnancy was 5.0%. Mothers with GDM and PGDM had higher rates of pre-eclampsia, multiple pregnancies, and preterm deliveries. Mothers with PGDM had significantly higher rates of intrauterine fetal demise (4.3%), congenital anomalies (12.8%), and small-for-gestational-age neonates (10.6%) compared to controls (0%, 3.2%, and 4.2%, respectively, P < 0.001). The risks for preterm or cesarean delivery, large-for-gestational-age neonate, respiratory morbidity, hypoglycemia, and polycythemia were increased in offspring of mothers with diabetes, especially PGDM.

Conclusions: Despite all the advancements in prenatal care, diabetes in pregnancy, both PGDM and GDM, is still associated with significant morbidities and complications in offspring. Better preconception and inter-pregnancy care might reduce these risks

Background: Stress hyperglycemia (SH) is a common finding in patients in pediatric emergency departments (PED) and has been related to increased morbidity and mortality.

Objectives: To assess the incidence of SH among children visiting the PED. To identify which diseases predispose patients to SH and whether they indicate a worse outcome.

Methods: Data were collected retrospectively from the medical records of all children aged 0–18 years who visited the PED during the years 2010–2014 and who had a glucose level of ≥ 150 mg/dl. Data collected included age, gender, weight, blood glucose level, presence or absence of a pre-existing or a new diagnosis of diabetes mellitus, and previous treatment with medications affecting blood glucose levels or with intravenous fluids containing dextrose. Data were collected regarding hospitalization, duration of hospitalization, discharge diagnosis, and survival status.

Results: The study population included 1245 children with SH, which comprised 2.6% of all patients whose blood glucose level was measured in the PED during the study period. The mean age of children with SH was 49 months; 709 (56.9%) were male. The mean blood glucose level was 184 mg/dl. The rate of hospitalization was 57.8%. The mean duration of hospital stay was 5.6 days and mortality rate was 0.96%. The majority were diagnosed with a respiratory illness.

Conclusions: SH is a common phenomenon among children evaluated in the PED and is associated with a high incidence of hospitalization. It may serve as an additional clinical indicator of disease severity.

Background: Coronary artery bypass grafting (CABG) for primary reperfusion in patients with ST elevation myocardial infarction (STEMI) has largely been superseded byf primary percutaneous coronary intervention (PCI) and is estimated to be performed in ≤ 5% of STEMI cases.

Objectives: To compare early CABG (within 30 days following admission) and primary PCI outcomes following STEMI.

Methods: We analyzed a retrospective cohort of patients hospitalized with acute STEMI for early reperfusion therapy between January 2008 and June 2016. Short- and long-term outcomes were assessed for patients with STEMI undergoing primary PCI vs. early CABG as reperfusion therapy.

Results: The study comprised 1660 STEMI patients, 38 of whom (2.3%) underwent CABG within 30 days of presentation. Unadjusted 30-day mortality was more than twice as high in the CABG group (7.5%) than in the PCI group (3.3%); however, it did not reach statistical significance. Similar results were demonstrated for mortality rates beyond 30 days (22% vs. 14%, P = 0.463). All patients undergoing CABG beyond 72 hours following admission survived past 2 years. Multivariate analysis found no differences between the two groups in long-term mortality risk. propensity score matched long-term mortality comparison (30 days–2 years) yielded a 22% mortality rate in the CABG groups compared with 14% in the PCI group (P < 0.293).

Conclusion: Early CABG was performed in only a minority of STEMI patients. This high-risk patient population demonstrated worse outcomes compared to patients undergoing PCI. Performing surgery beyond 72 hours following admission may be associated with lower risk.

Background: Behçet's disease is a multi-systemic chronic relapsing inflammatory disease, classified among the vasculitides. The heterogeneity of clinical manifestations challenges the disease management.

Objectives: To assess efficacy and safety of adalimumab in patients with active persistent Behçet's arthritis who did not respond to disease-modifying anti-rheumatic drugs and to assess the impact of treatment on the cytokine milieu.

Methods: Our cohort comprised 10 patients with active arthritis who received adalimumab in a 24-week investigator-initiated prospective open-label study. Patients who relapsed within 12 weeks following adalimumab discontinuation could enter a 3-year extension study. The patients underwent a comprehensive assessment including questionnaires and measurement of inflammatory cytokines, adalimumab serum levels, and anti-drug antibodies.

Results: A significant improvement was observed in arthritis, disease activity visual analogue scales, Behçet's disease current activity form, and interleukin-6 (IL-6) levels, but not in health assessment questionnaire and functional assessment of chronic illness therapy fatigue scale questionnaire. Resolution of oral and urogenital ulcers was achieved in all patients. Significant reduction of pain was reported by 40% of patients. The disease relapsed in 9 of 10 patients, within 2–6 weeks following adalimumab discontinuation. Of the 7 patients who continued the study, arthritis was resolved in 5. Two patients with high neutralizing antidrug antibodies titer relapsed.

Conclusions: Adalimumab treatment achieved a significant improvement in arthritis, mucocutaneous manifestations, and IL-6 levels in all study patients but only 40% reported significant pain reduction. The arthritis relapsed in 90% of patients following adalimumab discontinuation and long-term treatment was required.

Background: Transurethral prostatectomy is the gold standard surgical treatment of bladder outlet obstruction due to benign enlargement of the prostate, with more than 30,000 procedures performed annually in the United States alone. The success rate of this minimally invasive procedure is high and the results are durable. The development of urethral stricture is a long-term complication of the procedure and is noted in about 2% of patients. The stricture narrows the urethral lumen, leading to re-appearance of obstructive urinary symptoms. Traditionally, the evaluation of the stricture was performed by retrograde urethrography. Advancements in the fields of flexible endoscopy allowed rapid inspection of the urethra and immediate dilatation of the stricture in selected cases.

Objectives: To compare the efficacy of urethrography versus cystoscopy in the evaluation of urethral strictures following transurethral prostatectomy.

Methods: A retrospective review was conducted of a series of 32 consecutive patients treated due to post-transurethral resection of prostate (TURP) urethral stricture.

Results: Twenty patients underwent both tests. In 16 there was concordance between the two tests. Four patients had no pathological findings in urethrography but had strictures in cystoscopy. All strictures were short (up to 10 mm) and were easily treated during cystoscopy, with no complaints or re-surgery needed in 24 months follow-up.

Conclusions: Cystoscopy was superior to urethrography in the evaluation of post-TURP strictures. Strictures where often short and treated during the same procedure. We recommend that cystoscopy be the procedure of choice in evaluating obstructive urinary symptoms after TURP, and retrograde urethrography be preserved for selected cases.
