Background: As the lowest natural site on earth (-415 meters), the Dead Sea is unique for its high pressure and oxygen tension in addition to the unparalleled combination of natural resources. Furthermore, its balneotherapeutic resorts have been reported to be beneficial for patients with various chronic diseases.

Objectives: To evaluate the safety, quality of life (QoL), exercise capacity, heart failure, and arrhythmia parameters in patients with systolic congestive heart failure (SCHF) and implantable cardioverter defibrillator (ICD) following descent and stay at the Dead Sea.

Methods: The study group comprised patients with SCHF, New York Heart Association functional class II-III after ICD implantation. The following parameters were tested at sea level one week prior to the descent, during a 4 day stay at the Dead Sea, and one week after return: blood pressure, O2 saturation, ejection fraction (echocardiography), weight, B-type natriuretic peptide (BNP), arrhythmias, heart rate, heart rate variability (HRV), and QoL assessed by the Minnesota Living with Heart Failure questionnaire.

Results: We evaluated 19 patients, age 65.3 ± 9.6 years, of whom 16 (84%) were males and 18 (95%) had ICD-cardiac resynchronization therapy. The trip to and from and the stay at the Dead Sea were uneventful and well tolerated. The QoL score improved by 11 points, and the 6 minute walk increased by 63 meters (P < 0.001). BNP levels slightly increased with no statistical significance. The HRV decreased (P = 0.018). There were no significant changes in blood pressure, weight, O2 saturation or ejection fraction.

Conclusions: Descent to, ascent from, and stay at the Dead Sea resort are safe and might be beneficial in some aspects for patients with sCHF and an ICD.

Background: Transjugular kidney biopsy (TJKB) was first described in 1990. Indications for TJKB include uncorrectable bleeding disorders and conditions precluding the prone position. Objectives: To describe our initial experience with TJKB.

Methods: Between February 2008 and December 2009 all patients in whom percutaneous biopsy was contraindicated or unsuccessful underwent image-guided TJKB using a standard set with a 19 gauge core biopsy needle. Prospectively collected data included indication, number of needle passes, contrast dose, tissue yield, and complications.

Results: Twelve patients, age range 15–76 years (mean 55), underwent 14 TJKB procedures. Indications for the transjugular route included bleeding diathesis, dyspnea, ventral hernia, ascites, marked obesity, need for concomitant liver biopsy or concomitant insertion of tunneled dialysis catheter, discrepant kidney size, and failed percutaneous attempt. Thirteen biopsies were performed in 11 patients; in one patient TJKB was abandoned due to unfavorable renal vein anatomy. Four patients were premedicated with desmopressin and one with platelet transfusion, due to prolonged bleeding time. Three to six passes (mean 3.8) were made per biopsy, with an overall yield of 9.6 ± 8.2 glomeruli, providing a definite diagnosis in nine patients and a probable diagnosis in two. In two patients the first biopsy attempt yielded insufficient tissue, necessitating a repeat procedure. There were two minor bleeding episodes not requiring intervention. Serum creatinine was unchanged after the procedure and hemoglobin levels asymptomatically dropped by 0.3 ± 1.0 g/dl within 48 hours, requiring no treatment.

Conclusions: TJKB appears to safely allow adequate tissue diagnosis in patients at increased risk for complications from or contraindications to percutaneous renal biopsy.

Background: Meningiomas are frequently detected incidentally. Their natural history has not yet been established because it is difficult to predict the growth pattern. Therefore, the management, after the radiological diagnosis, is still controversial.

Objectives: To evaluate the clinical outcome and growth rate of conservatively treated meningiomas at our tertiary center, identify prognostic factors of tumor growth, and suggest guidelines based on the available data and our experience.

Methods: We reviewed the clinical records of 56 patients with 63 untreated meningiomas. Most were diagnosed incidentally. Clinical features and imaging findings at diagnosis and during follow-up were compared between growing and non-growing tumors. Potential patient- and tumor-related predictive factors for growth were analyzed.

Results: The study group included 46 women (52 meningiomas) and 10 men (11 meningiomas) aged 39–83 years. Mean tumor size was 18 ± 11 mm (range 3–70 mm) at diagnosis and 22 ± 11 mm (range 8–70 mm) at last follow-up; mean follow-up time was 65 ± 34 months (range 15–152 months). During follow-up 24 tumors (38%) grew at a rate of 4 mm per year; none became symptomatic. Only two prognostic factors were statistically significantly associated with low growth rate: older age and tumor calcifications.

Conclusions: Given our finding of a low growth incidence of meningiomas in the elderly, we support conservative management in patients aged 70 years or older. Calcifications into the meningioma are also indicative of slow growth, suggesting a conservative strategy. Surgery is recommended in younger patients in whom tumor growth occurs more often and a longer follow-up is necessary.

Background: The criteria for tonsillectomy for recurrent tonsillitis were established by prospective studies in the pediatric population and are applied to adults as well. No studies have been conducted to assess whether these guidelines are followed. 

Objectives: To examine the eligibility for tonsillectomy of tonsillectomized patients who were referred because of recurrent acute tonsillitis.

Methods: A retrospective case series in an ambulatory military otolaryngology clinic was conducted, and the medical records of 44 tonsillectomized patients who suffered from throat infections in the year before surgery were analyzed. The number of tonsillar infections that met the referral criteria was counted.

Results: The average number of throat infections that met the referral criteria was 1.89 per year. The average number of visits to the clinic due to upper respiratory tract infection was 12.92 (range 2–36) per year. The average number of visits for any cause was 45.13 (range 6–64) per year. One patient with eight documented throat infections met the criteria of more than six infections in the last year.

Conclusion: Although the referral criteria were not strictly met, we speculate that surgery was probably beneficial. This study shows that the indications for tonsillectomy referral are not strictly followed, and that new criteria for referral of adults for tonsillectomy need to be established.

Background: Mucositis and dermatitis are frequently encountered in patients treated with radiochemotherapy. Dead Sea products that contain minerals and different substances have proved effective in treating various skin diseases.

Objectives: To evaluate the effectiveness of Dead Sea products in reducing acute radiochemotherapy‑induced side effects in patients with head and neck cancer.

Methods: In this phase 2 study we compared the outcomes in 24 treated patients and 30 conventionally treated patients matched for age, tumor site, and type of treatment. The Dead Sea products comprised a mouthwash solution (Lenom®) and a skin cream (Solaris®) used three times daily for 1 week before, during, and up to 2 weeks after completion of radiotherapy. Mucositis and dermatitis were evaluated using common toxicity criteria.

Results: Thirteen treated patients (54%) had grade 1-2 and none had 3-4 mucositis, while 17 controls (57%) had grade 1-2 and 4 (13%) had grade 3-4 mucositis. Thirteen treated patients (54%) had grade 1-2 dermatitis; there was no instance of grade 3-4 dermatitis, while 11 patients in the control group (37%) had grade 1-2 and 5 (17%) had grade 3-4 dermatitis. More patients in the control arm needed a break than the patients in the treatment arm (P = 0.034[T1]).

Conclusions: The two Dead Sea products tested decreased skin and mucosal toxicity in head and neck cancer patients receiving radiochemotherapy.

Background: The association between antibiotic use in the community and antimicrobial resistance is known. Attention has recently focused on the type of agents being prescribed.

Objectives: To implement, evaluate and compare the efficacy of two community interventions programs – continuous versus seasonal medical education – oriented to primary care physicians with emphasis on appropriate use of antimicrobial drugs.

Methods: From October 2000 to April 2003 we conducted two interventions: a) a monthly educational campaign in selected clinics promoting appropriate diagnosis of common infectious diseases and prudent antibiotic use (continuous intervention group); and b) a massive educational campaign, conducted before two consecutive winters, promoting the judicious use of antibiotics for treating respiratory infections (continuous intervention group and seasonal intervention group). Sixteen similar clinics were randomized (8 to each group). The total antibiotic use was measured as defined daily dose/1000 patients/day, and compared between the groups. 

Results: The total use of antibiotics decreased between 1999-2000 and 2002-2003 in both groups, but slightly more significantly in the continuous intervention group. The DDD/1000 patients/day for the seasonal group in 1999-2000 was 27.8 vs. 23.2 in 2002-2003; and for the continuous group 28.7 in 1999-2000 vs. 22.9 in 2002-2003, a reduction of 16.5% and 20.0% respectively (p<0.0001). The main change in antibiotic use was noted for broad-spectrum antibiotics.

Conclusions: We present a successful community intervention program aimed to reduce unnecessary antibiotic use. Amplification of this type of intervention is imperative to stop the increase in antimicrobial resistance.

 Background: Monoclonal gammopathy of undetermined significance is defined by the presence of: low serum and/or urine monoclonal protein level; less than 10% plasma cells in bone marrow; normal serum calcium, creatinine and hemoglobin levels; and no bone lesions on full skeletal X-ray survey.

Objectives: To study the necessity of bone marrow examination for the diagnosis and clinical course of MGUS[1].

Methods: We retrospectively screened the medical records of all patients in whom monoclonal protein was found in the serum during 2001–2002 in the medical laboratories of Sapir Medical Center. Asymptomatic patients who had serum monoclonal immunoglobulin G < 3.0 g/dl or IgA[2] < 2.0 g/dl or IgM < 1.0 g/dl without anemia, renal failure, hypercalcemia or any bone lesions on skeletal survey were eligible. Full records of patients who were evaluated in the hematology clinic were available (group 1). The remaining patients were followed by their family physicians; thus we had access only to their electronic files including laboratory results and new diagnoses (group 2). Demographic and clinical parameters as well as clinical course were evaluated.

Results: Both groups (57 and 255 patients, respectively) had similar demographic, laboratory and clinical characteristics. Bone marrow examination was performed in 30 of 57 patients (group 1): 16 were normal, 8 had an excess of normal plasma cells, and 6 had excess of pathologic plasma cells. However, only in two of the latter six could a diagnosis of multiple myeloma be established. All group 1 patients were followed for 22 ± 11 months and only two developed overt multiple myeloma. During the same period, 6 of 255 patients (group 2) were diagnosed as multiple myeloma and 3 as MGUS in other hospitals. The rest had a stable course with no change in their laboratory values.

Conclusions: Our findings suggest that bone marrow examination should not be performed routinely in patients who fulfill strict clinical and laboratory criteria of MGUS.

 Background: Thrombosis is a major cause of morbidity and mortality in polycythemia vera. Hypercoagulability is principally due to hyperviscosity of the whole blood, an exponential function of the hematocrit. PV[1] is also associated with endothelial dysfunction that can predispose to arterial disease. Reduction of the red cell mass to a safe level by phlebotomy is the first principle of therapy in PV. This therapy may have some effect on the arterial compliance in PV patients.

Objectives: To estimate the influence of phlebotomies on large artery (C1) and small artery compliance (C2) in PV patients by using non-invasive methods.

Methods: Short-term hemodynamic effects of phlebotomy were studied by pulse wave analysis using the HDI-Pulse Wave CR2000 (Minneapolis, MN, USA) before and immediately after venesection (300–500 ml of blood). We repeated the evaluation after 1 month to measure the long-term effects.

Results: Seventeen PV patients were included in the study and 47 measurements of arterial compliance were performed: 37 for short-term effects and 10 for long-term effects. The mean large artery compliance (C1) before phlebotomy was 12.0 ml/mmHg x 10 (range 4.5–28.6), and 12.6 ml/mmHg x 10 (range 5.2–20.1) immediately after phlebotomy (NS). The mean small artery compliance (C2) before and immediately after phlebotomy were 4.4 mg/mmHg x 10 (range 1.2–14.3) and 5.5 mg/mmHg x 10 (range 1.2–15.6) respectively (delta C2–1.1, P < 0.001). No difference in these parameters could be demonstrated in the long-term arm.

Conclusions: Phlebotomy immediately improves arterial compliance in small vessels of PV patients, but this effect is short lived.

 Background: Full medical coverage may often result in overuse. Cost-sharing and the introduction of a co-payment have been shown to cause a reduction in the use of medical services.

Objectives: To assess the effects of the recently introduced co-payment for consultant specialist services on patients' utilization of these services in southern Israel.

Methods: Computerized utilization data on specialists' services for 6 months before and 6 months after initiation of co-payment were retrieved from the database of Israel's largest health management organization.

Results: A decrease of 4.5% was found in the total number of visits to Soroka Medical Center outpatient clinics and of 6.8% to community-based consultants. An increase of 20.1% was noted in the number of non-actualized visits at the outpatient clinics. A decrease of 6.2% in new visits was found in the hospital outpatient clinics and of 6.5% in community clinics. A logistic regression model showed that the residents of development towns and people aged 75+ and 12–34 were more likely not to keep a prescheduled appointment.

Conclusion: After introduction of a modest co-payment, a decrease in the total number of visits to specialists with an increase in "no-shows" was observed. The logistic regression model suggests that people of lower socioeconomic status are more likely not to keep a prescheduled appointment.
