Background: Heart failure (HF) patients with reduced ejection fraction (HFrEF) are frequently treated with sub-optimal doses of angiotensin converting enzyme-inhibitors (ACE-Is), angiotensin receptor blockers (ARBs), and beta blockers (BBs).

Objectives: To determine factors associated with attaining upper-range doses in patients with HFrEF.

Methods: We examined treatment in patients with left ventricular ejection fraction (LVEF) ≤ 40% in a community-based, dedicated heart-failure clinic. Upper-range doses were defined as ≥ 75% of target recommended doses by heart failure society guidelines.

Results: The majority of the 215 patients were men (82%); median age at presentation 73 years (interquartile range [IQR] 65–78) and LVEF of 30% (IQR 25–35%). Following the up-titration program, 41% and 35% of patients achieved upper-range doses of ACE-Is/ARBs and BBs, respectively. Higher body mass index (BMI) was the only parameter found to be associated with achieving upper-range doses of ACE-I/ARBs (odds ratio [OR] 1.13, 95% confidence interval [95%CI] 1.05–1.22, P = 0.001). More patients achieved this target as BMI increased, with a sharp decline in the highest obesity category (BMI ≥ 40 m²/kg). Attaining upper-range doses of BBs was associated with pre-existing diabetes mellitus (DM) (OR 2.6, 95%CI 1.34–5.19, P = 0.005); women were associated with attaining lower BBs doses (OR 0.34, 95%CI 0.13–0.90, P = 0.031).

Conclusions: Achieving upper-range doses of ACE-Is/ARBs and BBs in HFrEF outpatients in a treatment up-titration program were associated with greater BMI and DM, respectively. These findings may serve as benchmarks for up-titration programs.

Background: In February 2020, the World Health Organisation designated the name COVID-19 for a clinical condition caused by a virus identified as a cause for a cluster of pneumonia cases in Wuhan, China. The virus subsequently spread worldwide, causing havoc to medical systems and paralyzing global economies. The first COVID-19 patient in Israel was diagnosed on 27 February 2020.

Objectives: To present our findings and experiences as the first and largest center for COVID-19 patients in Israel.

Methods: The current analysis included all COVID-19 patients treated in Sheba Medical Center from February 2020 to April 2020. Clinical, laboratory, and epidemiological data gathered during their hospitalization are presented.

Results: Our 162 patient cohort included mostly adult (mean age of 52 ± 20 years) males (65%). Patients classified as severe COVID-19 were significantly older and had higher prevalence of arterial hypertension and diabetes. They also had significantly higher white blood cell counts, absolute neutrophil counts, and lactate dehydrogenase. Low folic acid blood levels were more common amongst severe patients (18.2 vs. 12.9 vs. 9.8, P = 0.014). The rate of immune compromised patients (12%) in our cohort was also higher than in the general population. The rate of deterioration from moderate to severe disease was high: 9% necessitated non-invasive oxygenation and 15% were intubated and mechanically ventilated. The mortality rate was 3.1%.

Conclusions: COVID-19 patients present a challenge for healthcare professionals and the whole medical system. We hope our findings will assist other providers and institutions in their care for these patients.

Background: Pancreatic injuries during nephrectomy are rare, despite the relatively close anatomic relation between the kidneys and the pancreas. The data regarding the incidence and outcome of pancreatic injuries are scarce.

Objectives: To assess the frequency and the clinical significance of pancreatic injuries during nephrectomy.

Methods: A retrospective analysis was conducted of all patients who underwent nephrectomy over a period of 30 years (1987–2016) in a large tertiary medical center. Demographic, clinical, and surgical data were collected and analyzed.

Results: A total of 1674 patients underwent nephrectomy during the study period. Of those, 553 (33%) and 294 patients (17.5%) underwent left nephrectomy and radical left nephrectomy, respectively. Among those, four patients (0.2% of the total group, 0.7% of the left nephrectomy group, and 1.36% of the radical left nephrectomy) experienced iatrogenic injuries to the pancreas. None of the injuries were recognized intraoperatively. All patients were treated with drains in an attempt to control the pancreatic leak and one patient required additional surgical interventions. Average length of stay was 65 days (range 15–190 days). Mean follow-up was 23.3 months (range 7.7–115 months).

Conclusions: Pancreatic injuries during nephrectomy are rare and carry a significant risk for postoperative morbidity.

Background: Male breast cancer (MBC) is a rare disease that is poorly understood. Treatment protocols are widely extrapolated from breast cancer in women.

Objectives: To review the experience with MBC of a single center in Israel over a period of 22 years.

Methods: This single center retrospective study evaluated all patients diagnosed with MBC over a period of 22 years (1993–2015). Data were extracted from patient medical charts and included demographics, clinical, surgical, and oncological outcomes.

Results: The study comprised 49 patients. Mean age at diagnosis was 64.1 ± 13.5 years. The majority were diagnosed at early stages (1A–2A) (54.4%), 30.6% were stage 3B mostly due to direct skin and nipple involvement, and 59.2% of the patients had node negative disease. All of the patients were diagnosed with invasive ductal carcinoma and 30.6% had concomitant ductal carcinoma in situ. Estrogen receptor (ER) status was predominantly positive and luminal B (HER2-) was the most common subtype. Of the patients, 18.4% were BRCA carriers. The majority of patients underwent mastectomy. Radiotherapy was delivered to 46.9% and hormonal therapy to 89.8%. Chemotherapy was administered to 42.9%. Overall survival was 79.6% with a median survival of 60.1 (2–178) months; 5- and 10-year survival was 93.9% and 79.6%, respectively. Progesterone receptor (PR)-negative patients had a significantly improved overall survival.

Conclusions: MBC has increasing incidence. PR-negative status was associated with better overall survival and disease-free interval. Indications to radiotherapy and hormonal therapy need standardization and will benefit from prospective randomized control trials.

Background: Temporary abdominal closure (TAC) surgical technique relates to a procedure in which the post-surgical abdominal wall remains open in certain indications. The Bogota bag (BB) technique is a tension-free TAC method that covers the abdominal contents with a sterilized fluid bag. There are very few reports of pediatric patients treated with this technique.

Objectives: To describe our institution’s 15 years of experience using the BB technique on pediatric patients.

Methods: A retrospective cohort study describing our experience treating patients with BB was conducted. The medical files of 17 pediatric patients aged 0–18 years were reviewed.

Results: Between January 2000 and December 2014, 17 patients were treated with BB at our medical center (6 females, median age 12 years). Indications for BB were a need for a surgical site re-exploration, mechanical inability for primary abdominal closure, and high risk for ACS development. Median BB duration was 5 days and median bag replacement was 2 days. Median ICU length of stay (LOS) was 10 days and hospital LOS was 27 days. The ICU admission and BB procedure was tolerated well by 6 patients who were discharged home without complications. Of the remaining 11 patients, 6 patients died during the admission (35%) and the others presented with major complications not related to the BB but to the patient's primary disease.

Conclusions: This report represents the largest series of children treated with BB. The technique is simple to perform, inexpensive, and has very few complications.

Falling from a height accounts for 14.1% of all hospital admissions for traumatic injury. In 5% of cases, the injury is severe or critical, and in 1.5%, it is fatal. The dangers of falling have been recognized since time immemorial. Indeed, the Bible instructs us to build a parapet around the roof of our home so that, “…you may not bring the guilt of bloodshed on your house if someone falls from it” (Deuteronomy 22:8). This commandment highlights the relatively simple and practical means by which we can prevent falls. It is also one of a series of ethical laws that are presented to help us understand and obey the larger Biblical precepts of loving one’s neighbor and guarding the sanctity of life. The concept teaches us that it is the responsibility of all individuals to be cognizant of others and to avoid harming people through negligence or carelessness. The aim of this article is to explain the commandment to build a parapet in the context of the risk of falling from a height and to expand on its wider implications. The present work was prompted in part by the alarming increase in fatal and near-fatal accidents in Israel in two particular populations.

Giacomo Ceruti was a renowned painter in northern Italy during the middle third of the 18th century, although he is not well-known today. He produced pictures in several different genres but his reputation after his death was based primarily on his portrayal of beggars and poor working people; hence, his posthumous nickname, il Pitocchetto, the little beggar. Of medico-artistic interest is the realism with which he depicted the hands of his impoverished subjects, a quality that enables them to be examined for signs of pathology or trauma.

The present article displays some representative examples of hand deformities in Ceruti’s paintings, thus extending into the 18th century the authors' previous research on medical aspects of art works from the 15th to the 17th century.

Background: Anastomotic leakage (AL) is a major complication following colorectal surgery, with many risk factors established to date. The incidence of AL varies in the medical literature and is dependent on research inclusion criteria and diagnostic criteria.

Objectives: To determine the incidence of and the potential risk factors for AL following colorectal surgery at a single academic medical center.

Methods: We retrospectively reviewed all operative reports of colorectal procedures that included bowel resection and primary bowel anastomosis performed at Sheba Medical Center during 2012. AL was defined according to the 1991 United Kingdom Surgical Infection Study Group criteria. Data were assessed for leak incidence within 30 days. In addition, 17 possible risk factors for leakage were analyzed. A literature review was conducted.

Results: This cohort study comprised 260 patients, and included 261 procedures performed during the study period. The overall leak rate was 8.4%. In a univariate analysis, male sex (odds ratio [OR] 3.37, 95% confidence interval [95%CI] 1.21–9.43), pulmonary disease (OR 3.99, 95%CI 1.49–10.73), current or past smoking (OR 2.93, 95%CI 1.21–7.10), and American Society of Anesthesiologist score ≥ 3 (OR 3.08, 95%CI 1.16–8.13) were associated with an increased risk for anastomotic leakage. In a multivariate analysis, male gender (OR 3.62, 95%CI 1.27–10.33) and pulmonary disease (OR 4.37, 95%CI 1.58–12.10) were associated with a greater risk.

Conclusions: The incidence of AL in the present study is similar to that found in comparable series. Respiratory co-morbidity and male sex were found to be the most significant risk factors.

Background: The use of oral midazolam as premedication to induce anxiolysis before surgical procedures under local anesthesia is widely accepted in plastic surgery. Rhinoplasty performed under local anesthesia is known to generate high levels of perioperative anxiety, thus the use of appropriate premedication is important. Oral midazolam has been shown to be safe in various procedures. However, the safety of oral midazolam before rhinoplasty has not been evaluated.

Objectives: To evaluate the safety of premedication with oral midazolam prior to rhinoplasty by analyzing the intraoperative blood oxygen saturation levels as predictors of adverse respiratory events.

Methods: We retrospectively reviewed the anesthesia records of 62 patients who underwent rhinoplasty under local anesthesia and received premedication with oral midazolam for anxiolysis between March 2017 and December 2017. The median age of the patients was 25.4 years, and they were all classified as American Society of Anesthesiologists class 1. The patients received 10 mg midazolam hydrochloride orally 1 hour prior to the procedure. Oxygen blood saturation was monitored using a pulse oximeter and recorded every 15 minutes.

Results: All the patients maintained blood oxygen saturation levels above 95% (median peripheral capillary oxygen saturation 99%) on room air, and they did not require supplemental intraoperative oxygen. There were no transient hypoxemic events during and following the procedure.

Conclusions: Our study confirmed the safety of oral midazolam premedication to reduce perioperative anxiety when performing rhinoplasty under local anesthesia.

Background: Pneumatic sleeves (PS) are often used during laparoscopic surgery and for prevention of deep vein thrombosis in patients who cannot receive anticoagulation treatment. There is very little information on the hemodynamic changes induced by PS and their effect on brain natriuretic peptide (BNP) in patients with severely reduced left ventricular ejection function (LVEF).

Objectives: To determine the safety and hemodynamic changes induced by PS and their effects on brain natriuretic peptide (BNP).

Methods: This study comprised 14 patients classified as New York Heart Association (NYHA) II–III with severely reduced LVEF (< 40%). We activated the PS using two inflation pressures (50 or 80 mmHg, 7 patients in each group) at two cycles per minute for one hour. We measured echocardiography, hemodynamic parameters, and BNP levels in each patient prior to, during, and after the PS operation.

Results: The baseline LVEF did not change throughout the activation of PS (31 ± 10% vs. 33 ± 9%, P = 0.673). Following PS activation there was no significant difference in systolic or diastolic blood pressure, the pulse measurements, or central venous pressure. BNP levels did not change after PS activation (P = 0.074).

Conclusions: The use of PS, with either low or high inflation pressures, is safe and has no detrimental effects on hemodynamic parameters or BNP levels in patients with severely reduced LVEF following clinical stabilization and optimal medical therapy.
