Objectives: To determine the effect of the Dead Sea climatotherapy on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Methods: A total of 119 patients participated in an observational prospective study carried out at the Deutsches Medizinisches Zentrum clinic, a medical skin care center specializing in climatotherapy. The patients completed questionnaires (Skindex-29) to quantify their quality of life at different time points: the day of arrival, the day of departure, and 3 and 6 months after the end of treatment.

Results: Marked improvement in the quality of life scores was measured between the time of arrival to time of departure and to 3 months after the end of treatment.

Conclusions: Dead Sea climatotherapy has a significant positive influence on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

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: Head lice move easily from head to head. The lack of safe, effective repellents leads to reinfestation.

Objectives: To test the efficacy of a slow-release citronella formulation as a repellent against the head louse.

Methods: During 4 months in 2003 a randomized, placebo-controlled double-blind clinical study was conducted in four elementary schools; 103 children were treated with the test formulation and 95 with a placebo.

Results: A significant difference was observed during the second examination 2 months later, when 12.0% of the children treated with the test repellent and 50.5% of those treated with placebo were infested with lice. A significant difference was also observed at the third examination 2 months later, when 12.4% of the children treated with the test repellent and 33.7% treated with placebo were infested. Overall, there were significant differences between those treated with the repellent and those treated with the placebo (15.4% and 55.1% respectively, P < 0.0001). Side effects were observed in 4.4% of children who disliked the odor of the formulation, and an additional 1.0% who complained of a slight itching and burning sensation.

Conclusions: Use of an effective repellent could significantly lower the incidence of reinfestations, which would lower expenditure on lice control, including pediculicides, combs and products for nit removal, and the time spent on treatment and removal of the nits.

Background: Head louse infestations are prevalent worldwide. Over the past 20-25 years, 15-20% of all children in Israel between 4 and 13 years of age have been infested with head lice; This is mainly due to the existence of ineffective pediculicides on the market.

Objective: To examine the pediculicidal efficacy and safety of a natural remedy (”Chick-Chack") and to compare it in an open clinical study with a known pesticide spray.

Methods: The natural remedy, which contains coconut oil, anise ail and ylang ylang oil:, was applied to the hair of infested.children three times at 5 day intervals. Each treatment lasted for 15 minutes. The control pediculicide was a spray, formulation containing permethrin, malathion, piperonyl butoxide, isododecane and propellant gas, which was applied twice for 10 minutes with a 10 day interva1 between applications.

Results: Of 940 Children, aged 6-14 years, from six schools in Jerusalem who were examined for head louse infestastion,199 (21:.2÷/) were infested with lice and eggs, while 164 (17.4% ) were infested only  with nits. Altogether, 119 children were randomly treated with either the natural remedy or the control product. Treatment was successful with the natural remedy  in 60 children (92.3%) and with the control pediculicide in 59 children (92.2%). There were no significant side effects associated with either formulation.

Conclusions: The natural remedy was very effective in controlling  louse infestations under clinical conditions and caused no serious side effects.
