Experimental and clinical data suggest a causal relationship between immunological and inflammatory processes and heart failure. Inflammatory processes may be involved in the pathogenesis of heart failure and may play a role in the progression of ventricular dysfunction. In the last decade several immunological methods were developed that tried to address these questions and overcome the inflammatory and immunological insults. We hope that the present review will increase awareness of new treatment options and encourage researchers and physicians to investigate this novel approach to treat patients with heart failure.

Ten years ago we published a review updating current knowledge on heart failure. We summarized that heart failure is a neuro-humoral and inflammatory syndrome, and that pro-inflammatory cytokines are involved in cardiac depression and in the complex syndrome of heart failure. We suggested that understanding the involvement of these cytokines may enable us to reverse cardiac depression and heart failure. Now we know that there are several mechanisms involved in this syndrome, including inflammation, nitric oxide-dependent pathways, apoptosis, reactive oxygen species, and mitochondrial energy metabolism. This review will focus on the up-to-date mechanistic aspects of heart failure, including clinical trials that have contributed to our better understanding of this entity.

Background: The Beer Sheva Psoriasis Severity Score is a novel instrument for the assessment of psoriasis severity, designed for use in routine clinical conditions.

Objective: To identify the main factors of the BPSS[1].

Methods: The sample used to study the BPSS comprised 70 patients with psoriasis vulgaris treated by climatotherapy at the Dead Sea. Psoriasis severity was assessed using BPSS and PASI (Psoriasis Area and Severity Index). Factor analysis was used to identify the main factors of BPSS. Internal consistency analysis was performed. Correlation matrices were generated to compare BPSS factors.

Results: Factor analysis demonstrated that BPSS included six factors that explained 74.0% of the variance as follows: patient assessment 26.0%; physician assessment 13.2%; palms and soles involvement 11.9%; genitals, nails, and pruritus 9.0%; face involvement 7.3%; and scalp involvement 6.6%. Total scale Cronbach’s alpha was 0.76; alpha for the factors ranged between 0.39 and 0.81.

Conclusion: The major factors of BPSS were identified. BPSS may be used as a comprehensive tool for measuring psoriasis severity.

Background: Rehabilitation camps can improve exercise tolerance and nutrition in cystic fibrosis patients.

Objectives: To assess weight gain, pulmonary function tests and daily symptoms in European CF[1] patients attending a rehabilitation camp at the Dead Sea, Israel.

Methods: We conducted a retrospective study assessing 94 CF patients who participated in winter camps held at the Dead Sea, Israel from 1997 to 2000. The camp program included daily physiotherapy, physical activities, and a high caloric diet. We assessed weight gain, pulmonary function tests, oxyhemoglobin saturation and daily symptoms before (pre), on departure (dep), and up to 3 months after the 3 week rehabilitation camp post). All data were analyzed by ANOVA for repetitive measurements. P < 0.05 was considered significant.

Results: Lung function tests and oxyhemoglobin saturation taken before, on departure and 3 months after camp were available for 35 patients. Forced expiratory volume in the first second (% predicted, average ± SD) improved by 8.2 ± 2.3% (pre, dep, post, P < 0.05). Oxyhemoglobin saturation mildly improved (1 ± 0.3%, pre, dep, post, P < 0.05). Forced vital capacity (% predicted) increased by 3.9 ± 1.2%, but was not significant (P = 0.19). Total body weight of 89 patients improved by 1.9 ± 0.9% during the camp time (P < 0.05, t-test), and in a group of 24 patients weight continuously increased up to 5.0 ± 1.7% at 3 months after the camp (P = 0.004, ANOVA).

Conclusions: In this attrition-limited retrospective study, European CF patients improved their pulmonary function and gained weight during and up to 3 months after a 3 week rehabilitation winter camp at the Dead Sea, Israel.

Background: Most Israeli males aged 16–17 undergo a thorough medical examination prior to recruitment into the army. During the last 50 years, extensive data have been gathered enabling a study of time trends in the prevalence of common diseases in this age group.

Objectives: To examine the current prevalence of common diseases, compare the results with those of previous cohorts, and assess the influence of the massive immigration during the 1990s.         

Methods: The health examination at the recruitment centers includes a medical history, complete physical examination, and review of medical documentation provided by the family physician. If needed, additional tests and referral to specialists are ordered. The prevalence of selected diseases and severity was drawn from the computerized database of the classification board. Two cohorts, 1992–94 and 2003–04, were examined and compared with three previous cohort studies in 1957–61, 1977–78 and 1982–84. Data were stratified according to origin and country of birth.

Results: The prevalence of asthma increased dramatically during the years from 10.2 per 1000 examinees in 1957–61 to 111.6 per 1000 examinees in 2003–04. The prevalence of tuberculosis declined and then increased from 0.6 per 1000 adolescents in 1982–84 to 2.4 per 1000 adolescents in 2003–04. The prevalence of type 1 diabetes mellitus increased from 0.2 cases per 1000 examinees in 1957–61 to 0.8 cases in 1977–78 and 1982–84 and 0.9 cases per 1000 examinees in 2003–04. The prevalence of severe heart defects and severe epilepsy declined in the last 20 years (1.4 and 1.7 cases per 1000 examinees in the 1982–84 cohort to 0.4 and 0.3 cases per 1000 examinees in the 2003–4 cohort respectively). The patterns of disease prevalence were different for immigrants: tuberculosis was more common while asthma and allergic rhinitis were less prevalent.

Conclusions: The prevalence of common diseases among adolescents in Israel has changed over the last 50 years. There is a different pattern for immigrants and for those born in Israel.

 Background: Previous assessments of maternal group B Streptococcus carrier rates in women delivering at Shaare Zedek Medical Center ranged between 3.5 and 11% with neonatal sepsis rates of 0.2–0.9/1000 live births. Because of low colonization and disease rates, routine prenatal cultures of GBS[1] were not recommended, and intrapartum prophylaxis was mainly based on maternal risk factors.

Objectives: To determine whether this policy is still applicable. 

Methods: We performed prospective sampling and follow-up of women admitted for labor and delivery between February 2002 and July 2002. Vaginal and rectal cultures were obtained before the first pelvic examination. GBS isolation was performed using selective broth medium, and identified by latex agglutination and serotyping. Demographic data were collected by means of a standardized questionnaire. Data on the newborns were collected throughout 2002.

Results: Of the 629 sampled women, 86 had a positive culture and a carrier rate of 13.7%. A borderline significantly higher carriage rate was observed among mothers of North American origin (21% vs. 13.1%, P = 0.048), and a higher attack rate in their infants (3.8/1000 compared with 0.5/1000 live births in our general maternal population, P = 0.002). Eight newborns had early-onset neonatal GBS sepsis (a rate of 0.8/1000 live births), but none of them benefited from intrapartum antibiotic prophylaxis.

Conclusions: An increased neonatal disease rate was observed in a population with a higher colonization rate than previously seen. In lieu of the higher carrier rates, we now recommend routine prenatal screening for GBS in our perinatal population.

Background: Metastatic melanoma is an aggressive and highly malignant cancer. The 5 year survival rate of patients with metastatic disease is less than 5% with a median survival of only 6–10 months. Drugs like dacarbazin (DTIC) as a single agent or in combination with other chemotherapy agents have a response rate of 15–30%, but the duration of response is usually short with no impact on survival. Interleukin-2-based immunotherapy has shown more promising results. The National Institutes of Health recently reported that lymphodepleting chemotherapy, followed by an adoptive transfer of large numbers of anti-tumor specific tumor-infiltrating lymphocytes, resulted in an objective regression in 51% of patients.

Objectives: To introduce the TIL[1] technology to advanced metastatic melanoma patients in Israel.

Methods: We generated TIL cultures from tumor tissue, choosing those with specific activity against melanoma and expanding them to large numbers.

Results: TIL cultures from nine patients were established and examined for their specific activity against the patients' autologous tumor cells. Twelve TIL cultures derived from 5 different patients showed the desired anti-tumor activity, making those 5 patients potential candidates for the therapy.

Conclusions: Pre-clinical studies of the TIL technology in a clinical laboratory set-up were performed successfully and this modality is ready for treating metastatic melanoma patients at the Sheba Medical Center's Ella Institute.

 Background: As complementary and alternative medicine is gaining popularity among health consumers, diagnostic screening tools based on neuroreflexology are also being developed. These techniques, which are based on the rationale that measurement of electrical impedance of specific dermatomes reflects corresponding internal organ pathologies, have not yet been the subject of conventional scientific research.

Objectives: To determine the effectiveness of a neuroreflexology-based screening test, specifically the Medex device (Medex Screen Ltd.), for diagnosing patients undergoing conventional internal organ assessment, in a hospital setting.

Methods: Patients admitted to an internal medicine department, who met the inclusion criteria and agreed to participate, underwent conventional medical evaluation that included past medical history and physical examination. Another examination was conducted by a second physician using the Medex device to determine internal organ pathologies. A third researcher compared the actual “conventional” diagnosis with the Medex device output using standard statistical analysis.   

Results: Overall, 150 patients participated in the study. Correlation was significant for all categories (P < 0.01) except for blood and lymphatic disease. A high sensitivity (>70%) was measured for cardiovascular, respiratory, gastrointestinal and genitourinary diseases. The highest measure of agreement, as represented by the Cohen-Kappa factor, was found for respiratory disease (0.57).

Conclusions: Although the exact mechanism is not entirely clear, measurement of electroskin impedance of dermal-visceral zones has the potential to serve as a screening tool for inner organ pathologies. Further research should be conducted to create more evidence to support or dispute the use of this technique as a reliable diagnostic tool.
