Background: Surgery is considered the mainstay of treatment for esophageal carcinoma. Transhiatal esophagectomy with cervical esophagogastric anastomosis is considered relatively safe with an oncological outcome comparable to that using the transthoracic approach.

Objectives: To review the results of the first 100 transhiatal esophagectomies performed in a single Israeli center.

Methods: The records of all patients who had undergone transhiatal esophagectomy during the period 2003–2009 were reviewed. The study group comprised the first 100 patients. All patients who had undergone colon or small bowel transposition were excluded. Indications for surgery included esophageal cancer, caustic injury and achalasia.

Results: The median follow-up period was 19.5 months. The anastomotic leakage rate was 15% and all were managed successfully with local wound care. The benign stricture rate was 10% and all were managed successfully with endoscopic balloon dilation. Anastomotic leakage was found to be a risk factor for stricture formation. Overall survival was 54%. Response to neoadjuvant therapy was associated with a favorable prognosis.

Conclusions: Transhiatal esophagectomy is a relatively safe approach with adequate oncological results, as long as it is performed in a high volume center.
 

Background: Some specialists and policy makers advocate progression of the mental health reform in Israel by transferring beds from psychiatric to general hospitals.

Objectives: To compare the demographic, diagnostic and psychopathological profiles of psychiatric inpatients hospitalized in psychiatric and general hospitals, as well as their patterns of drug abuse and to estimate the preparedness of general hospitals for the possible expansion of their psychiatric services.

Methods: Between 2002 and 2006 a total of 250 patients were consecutively admitted to the Jerusalem Mental Health Center-Kfar Shaul Hospital and 220 to the psychiatric department of Sheba Medical Center, a general hospital in central Israel; the patients’ ages ranged from 18 to 65. The two groups were compared for demographic features, psychiatric diagnoses and severity of psychopathology (utilizing PANSS, HAD-21, YMRS rating scales). Drug abuse was diagnosed by urine analyses and self-report.

Results: The patients in the psychiatric hospital were significantly younger, predominantly male, and more dependent on social security payments. In the general hospital, diagnoses of affective and anxiety disorders prevailed, while in the psychiatric hospital schizophrenic and other psychotic patients constituted the majority. The patients in the general hospital were decidedly more depressed; in the psychiatric hospital, notably higher rates of manic symptoms as well as positive, negative and general schizophrenic symptoms were reported. For the most abused substances (opiates, cannabis and methamphetamines) the rates in the psychiatric hospital were significantly higher.

Conclusions: The differences between the two groups of inpatients were very pronounced, and therefore, the transferring of psychiatric beds to general hospitals could not be done without serious and profound organizational, educational and financial changes in the psychiatric services of general hospitals. Since each of the two inpatient systems has particular specializations and experience with the different subgroups of patients, they could coexist for a long time.
 

Background: The effect of anti-platelet drugs on surgical blood loss and perioperative complications has not been studied in depth and the management of surgical patients taking anti-platelet medications is controversial.

Objective: To assess the effect of anti-platelet therapy on perioperative blood loss in patients undergoing appendectomy either laparoscopically or via open surgery.

Methods: We reviewed the files of all patients > 40 years old who underwent open or laparoscopic appendectomies from 2007 to 2010. Excluded were patients with short hospitalization and no follow-up of hemoglobin level, patients on warfarin treatment and patients who underwent additional procedures. Estimation of blood loss was based on decrease in hemoglobin level from admission to discharge. Risk factors for blood loss, such as anti-platelet therapy, age, gender, surgical approach, surgical time, surgical findings and complications, were analyzed.

Results: The final cohort included 179 patients (mean age 61 ± 14 years, range 40–93) of whom 65 were males. The mean perioperative hemoglobin decrease was 1.59 ± 1.07 mg/dl (range 0–5 mg/dl). Thirty-nine patients received anti-platelet therapy prior to surgery and 140 did not. No significant differences in decrease of hemoglobin level were found between patients receiving anti-platelet therapy and those who were not (1.73 ± 1.21 vs. 1.55 ± 1.02 mg/dl, P = 0.3). In addition, no difference was found between patients on anti-platelet therapy operated laparoscopically and those operated in an open fashion (1.59 ± 1.18 vs. 2.04 ± 1.28 mg/dl, P = 0.29). Five patients required blood transfusions, two of whom were on anti-platelet therapy. Blood loss was significantly greater in patients with a perforated appendicitis and in those with an operative time of more than one hour.

Conclusions: Anti-platelet therapy does not pose a risk for increased blood loss following emergent appendectomy performed either laparoscopically or in an open fashion.
 

Background: Music therapy has been recommended as an adjuvant therapy for both preterm infants and mothers during their stay in the neonatal intensive care unit (NICU), and has been shown to have beneficial effects.

Objectives: To study the usefulness of combining live harp music therapy and kangaroo care (KC) on short-term physiological and behavioral parameters of preterm infants and their mothers in the NICU setting.

Methods: Included in this study were stable infants born between 32 and 37 weeks of gestation, with normal hearing .Mother-infant dyads were randomly assigned to KC and live harp music therapy or to KC alone. Using repeated measures, neonatal and maternal heart rate, oxygen saturation and respiratory rate were recorded along with neonatal behavioral state and maternal anxiety state. Maternal age, ethnicity, education, and love of music were documented.

Results: Fifty-two mother-infant dyads were tested. Compared with KC alone, KC and live harp music therapy had a significantly beneficial effect on maternal anxiety score (46.8 ± 10 vs. 27.7 ± 7.1, respectively, P < 0.01). Infants’ physiological responses and behavior did not differ significantly. No correlation was found between mothers’ age, ethnicity, years of education and affinity for music, and anxiety scores (P = 0.2 to 0.5 for all four variables).

Conclusions: KC combined with live harp music therapy is more beneficial in reducing maternal anxiety than KC alone. This combined therapy had no apparent effect on the tested infants’ physiological responses or behavioral state.
 

Background: Fractures of the humerus in neonates can pose a diagnostic challenge, especially when the fracture occurs in the proximal or distal epiphysis.

Objectives: To review our experience in the diagnosis and treatment of birth-related humeral fractures.

Methods: Between the years 2001 and 2009, seven newborn patients and two patients treated in the neonatal intensive care unit sustained a fracture of the humerus. Four of the fractures occurred in the humeral shaft, three in the proximal epiphysis and two in the distal epiphysis. In all the newborn patients the diagnosis was made on the first day of life using radiography and ultrasonography. The fractures of the shaft and of the distal epiphysis were treated by gentle manipulation and casting, and the fractures of the proximal epiphysis were treated by swaddling.

Results: All of the patients demonstrated fracture union within 2 weeks, and radiographs at the age of 6 months demonstrated complete remodeling of the fracture.

Conclusions: Ultrasonography is a simple, readily available and inexpensive modality for the diagnosis of birth-related fractures of the humerus, especially in the yet unossified epiphyses.

This medical history essay claims a medical fraud committed by the authorities, and used as a pretext for the November 1938 anti-Jewish Kristallnacht pogrom throughout the Third Reich. The suggested conspiracy covered up the real cause of death of the German Embassy's secretary in Paris. Baron Ernst vom Rath had been shot by a Jewish teenager who was frantic because of the plight of his family. A surgical analysis of the victim's injuries, and of the medical attention he received, suggests the likelihood of medical malpractice which led to his preventable demise.
 

Background: Diarrhea is a leading cause of child mortality worldwide. Rotavirus is one of the most common causes of severe diarrhea and dehydration in children.

Objectives: To compare the demographic, clinical and laboratory characteristics of patients with rotavirus gastroenteritis to those with other causes of gastroenteritis.

Methods: The medical records of children aged 0–18 years hospitalized with acute gastroenteritis in our facility between 1 January 2004 and 31 March 2006 were retrieved. Patients with rotavirus gastroenteritis were compared with patients who were rotavirus negative.

Results: The study group comprised 533 patients; 202 tested positive for rotavirus and 331 tested negative. Compared to patients with rotavirus-negative gastroenteritis, patients with rotavirus-positive gastroenteritis had a higher incidence of vomiting (185/202 vs. 212/331, 92% vs.  64%, P < 0.001), lethargy (67 vs. 51, 33% vs. 15%, P < 0.001), and dehydration (81 vs. 78 vs. 40% vs. 24%, P < 0.001). The need for intravenous rehydration therapy and the duration of hospitalization were higher in patients with rotavirus gastroenteritis.

Conclusions: Vomiting and dehydration are more common in hospitalized children with rotavirus gastroenteritis than in children with gastroenteritis due to other causes.
 

Background: Major changes in the evaluation and treatment of curable colorectal cancer (CRC) have emerged in the last two decades. These changes have led to better patient outcome over time.

Objectives: To evaluate the impact of these changes as reflected in the difference in long-term outcome of a consecutive group of recently laparoscopically operated curable CRC[1] patients and a consecutive group of patients operated 20 years earlier in the same department.

Methods: Data of the new group were taken from our prospectively collected data of patients who underwent elective laparoscopic surgery for CRC in recent years. Data regarding patients operated on 20 years ago were retrieved from previous prospectively collected data on the long-term survival of CRC patients operated in the same department.

Results: The recently operated group comprised 203 patients and the previous group 199 patients. Perioperative mortality was 0.5% in the new group versus 1.5% in the old group (not significant). There were more early-stage and more proximal tumors in the recently operated group. A Kaplan-Meier 5-year survival analysis revealed no difference between stage I patients of the two groups. However, there was a significant increase in 5-year survival in the new group for stage II (85% vs. 63%, P = 0.004) and for stage III patients (57% vs. 39%, P = 0.01). This trend was maintained after removing the rectal cancer patients from the calculated data.

Conclusions: We have demonstrated improved survival for stage II and III CRC patients over a 20-year period in the same medical center. This change most likely reflects advances both in imaging techniques leading to more accurate staging and in adjuvant treatments.

Background: Ultraviolet B (UVB) rays are required by the skin for the production of vitamin D. The intensity of UVB at the Dead Sea area is the lowest in the world. Low vitamin D levels are often associated with musculoskeletal symptoms.

Objectives: To assess the effectiveness of climatotherapy at the Dead Sea on the production of vitamin D in Norwegian patients suffering from various rheumatic diseases and to investigate possible associations between increased vitamin D serum levels, musculoskeletal symptoms and disease severity.

Methods: Sixty Norwegian patients who came to the Dead Sea area for 21 days of medical rehabilitation were divided into three groups according to their diagnosis: chronic pain syndromes, i.e., low back pain or fibromyalgia (Group 1, n=33); rheumatoid arthritis (Group 2, n=16); and osteoarthritis (Group 3, n=11). Serum 25-hydroxyvitamin D (25-OH-D) levels were determined at arrival and prior to departure. The treatment protocol included daily sun exposure (climatotherapy), bathing in the Dead Sea and mineral spring water (balneotherapy), mud applications and fitness classes.

Results: 25-OH-D serum levels increased significantly from 71.3 ± 26.6 nM at arrival to 89.3 ± 23.2 nM prior to departure (P < 0.001). Adjusted for the initial levels of pain (assessed by a visual analog scale) and disease severity, a direct correlation was observed between increased 25-OH-D serum levels and pain reduction (P = 0.012) and reduction of disease severity (P = 0.02).

Conclusions: Climatotherapy at the Dead Sea induces significant changes in vitamin D. Increased 25-OH-D serum levels are associated with reduced musculoskeletal pain and disease severity.
 

Background: Esophageal perforations and postoperative esophageal leaks are associated with substantial morbidity and mortality and pose a difficult therapeutic challenge. 

Objectives: To evaluate the outcome of removable self-expanding metallic stents (SEMS) as a treatment for postoperative leaks and perforations of the esophagus and stomach.

Methods: We conducted a retrospective study of all patients in one medical center who underwent temporary insertion of a covered plastic stent for postoperative leaks and perforations of the esophagus and stomach from June 2009 to February 2010. Data were retrieved from hospital and outpatient clinical data charts. Data included indication for insertion, post-insertion outcome including stent complications, and follow-up after stent removal.

Results: The indications for stent insertion were postoperative leak in four patients and postoperative esophagopleural fistula in one patient. Three of the patients had a leak at the gastro-esophageal junction following laparoscopic sleeve gastrectomy. In all cases the stent insertion was completed successfully. In three patients the stent migrated distally. In two of these three it was repositioned or replaced endoscopically, and in the third it was excreted in the feces. Stents were removed electively after 6 to 7 weeks. All patients recovered fully and were discharged from the hospital.

Conclusions: SEMS insertion may have an important role in the management of postoperative leaks and perforations of the esophagus and stomach and should be considered in such cases.
 

Background: Diabetic retinopathy is a leading cause of adult blindness and accounts for about 10% of cases of legal blindness in Israel. Only about half of the patients with diabetes in Israel have regular eye examinations.

Objectives: To evaluate, for the first time in southern Israel, a new service for diabetic retinopathy screening that uses a mobile non-mydriatic mobile fundus camera in primary care patients.

Methods: Diabetic members of the largest health fund in southern Israel and over 18 years old were invited for non-mydriatic fundus examination between January and October 2009. Screening was performed by a trained photographer using the Topcon TRC NW-6S non-mydriatic camera in nine primary care centers.

Results: A total of 4318 diabetic patients were screened, of whom 53% were classified as normal. The incidence of diabetic retinopathy was 15.8% (1.2% had proliferative retinopathy and 2.4% had suspected macular edema and were referred for laser treatment). Other possible sight-threatening conditions were detected in 9.3%. Fundus pictures were inadequate for assessment in 16% of cases.

Conclusions: Diabetic retinopathy screening with a mobile non-mydriatic fundus camera improved the quality of care for diabetic patients in southern Israel. This screening method identified patients requiring prompt referral to the ophthalmologist for further complete eye examination. Extending this screening program to other areas in the country should be considered.
 

Background: Acute renal failure (ARF) is a common complication in critically ill children. It is known as an important predictor of morbidity and mortality in this population. Data on the factors affecting the choice of renal replacement therapy (RRT) modality and its impact on mortality of children with ARF[1] are limited.

Objectives: We retrospectively studied 115 children with ARF necessitating RRT[2] during the period 1995–2005 to evaluate the effect of several prognostic factors as well as RRT type on their immediate outcome.

Methods: The data collected from charts included demographics, primary disease, accompanying medical conditions, use of vasopressor support, indications for dialysis, RRT modality, and complications of dialysis. Categorical variables were analyzed using chi-square or Fisher’s exact tests. Variables associated with mortality (P < 0.1) at the univariable level were studied by a multivariable logistic regression model.

Results: The most common cause of ARF was congenital heart disease (n=75). RRT modalities included peritoneal dialysis (PD) (n=81), hemodialfiltration (HDF) (n=31) and intermittent hemodialysis (IHD) (n=18). Median RRT duration was 4 days (range 1–63 days). Overall mortality was 52.2%. IHD[3] was associated with the best survival rate (P < 0.01 vs. PD[4] and HDF[5]), while children treated with HDF had the worse outcome. Hemodynamic instability and systemic infections were associated with greater mortality, but the rate of these complications did not differ between the study groups.

Conclusions: Our results suggest that IHD[6] when applied to the right patient in an appropriate setting may be a safe and efficient RRT modality in children with ARF. Randomized prospective trials are needed to further evaluate the impact of different RRT modalities on outcome in children with ARF.

Background: During military escalations emergency departments provide treatment both to victims of conflict-related injuries and to routine admissions. This requires special deployment by the hospitals to optimize utilization of resources.

Objectives: To evaluate “routine” visits to the ED[1] during Operation Cast Lead in Israel in 2008–2009.

Methods: We obtained data regarding routine visits to the ED at Soroka University Medical Center throughout OCL[2]. The visits one month before and after OCL and the corresponding periods one year previous served as controls.

Results: The mean number of daily visits throughout the study period (126 days) was 506 ± 80.9, which was significantly lower during OCL (443.5 ± 82) compared with the reference periods (P < 0.001). Compared to the reference periods, during OCL the relative rates were higher among Bedouins, visitors from the region closest to the Gaza Strip (< 30 km), patients transported to the ED by ambulance and patients of employment age; the rates were lower among children. No difference in the different periods was found in the rate of women patients, distance of residence from Beer Sheva, rate of patients referred to the ED by a community physician, and hour of arrival. The overall in-hospital admission rate increased during OCL, mainly in the internal medicine and the obstetric departments. There was no change in the number of in-hospital births during OCL; however, the rate of preterm labors (32–36 weeks) decreased by 41% (P = 0.013).

Conclusions: Throughout OCL the number of routine ED visits decreased significantly compared to the control periods. This finding could help to optimize the utilization of hospital resources during similar periods.
