Background: Wounds of the lower extremities are a significant problem, being severe and costly to treat. Adjunctive treatment with hyperbaric oxygenation (HBOT) has proven to be a useful and cost-effective means of treating ischemic wounds, mainly in diabetic patients.

Objectives: To describe patients with ischemic wounds treated at the Rambam and Elisha Hyperbaric Medical Center and their wound improvement following HBOT.

Methods: We conducted a retrospective cohort study of all patients (N=385) treated in the center during 1998–2007 for ischemic non-healing wounds in the lower extremities.

Results: The mean age of the patients was 61.9 years (SD 13.97). Most of them were diabetic (69.6%) and male (68.8%). Half of the subjects had a wound for more than 3 months prior to undergoing pre-HBOT transcutaneous oximetry (TcPO₂) testing. Most of the wounds were classified as Wagner degree 1 or 2 (39.1% and 46.2% respectively). The median number of treatments per patient was 29. Only 63.1% of patients had continuous treatments. Approximately 20% of patients experienced mild side effects. An improvement occurred in 282 patients (77.7%) following HBOT: 15.2% fully recovered, 42.7% showed a significant improvement (and were expected to heal spontaneously), and 19.8% a slight improvement.

Conclusions: HBOT can benefit the treatment of non-healing ischemic wounds (especially when aided by pretreatment TcPO₂ evaluation; data not shown). Our experience shows that this procedure is safe and contributes to wound healing.

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: Multiple sclerosis (MS) is a common demyelinating disorder of the central nervous system (CNS) and although it is a well-established autoimmune disease its ethiopathogenesis has yet to be fully elucidated. The disease may present in several clinical forms that are closely associated with disease morbidity. In recent years various environmental and hormonal factors have been implicated in the pathogenesis of autoimmunity.

Objectives: To evaluate ferritin and prolactin levels in MS patients and their correlation with clinical manifestations of the disease.

Methods: Serum samples from 150 multiple sclerosis patients were evaluated for demographic characteristics, clinical parameters as well as prolactin and ferritin levels utilizing the Liaison chemiluminescent immunoassays (DiaSorin, Italy). Sera from 100 matched healthy donors were used as controls.

Results: Hyperprolactinemia was documented in 10 of 150 MS patients (6.7%) and hyperferritinemia in 12 (8%), both of which were significantly more common in this group compared with healthy controls (P ≤ 0.01 and P = 0.02 respectively). Among female MS patients, elevated prolactin levels were related to the secondary progressive type of disease (P = 0.05), whereas hyperferritinemia was associated with male gender (P = 0.03) and with the relapsing progressive type of the disease (P = 0.02). An inverse association was found between hyperferritinemia and the relapsing-remitting type of MS in male patients (P = 0.05)

Conclusions: Our results suggest a plausible association between these biomarkers and certain clinical types and gender among MS patients. Further studies combining clinical data, CNS imaging and these markers are warranted.
 

Background: Hypovitaminosis D has been shown to be extremely common in various regions around the world, mostly at high latitudes. Israel is characterized by certain features – cultural (e.g., ethnic isolates) and geographic (e.g., sunny climate) – that have been identified for their possible association with vitamin D status.

Objectives: To conduct an ecological study on a representative sample of the population of Israel, testing vitamin D status across age groups, genders, ethnic groups, and seasons.

Methods: We obtained serum samples from 195 healthy Israeli volunteers representing a broad demographic spectrum. Serum concentrations of 25(OH)D were measured with the commercial kit Liaison 25(OH)D Assay (DiaSorin, Italy).

Results: The mean vitamin D level for the entire cohort was surprisingly low (22.9 ± 10.1 ng/ml), with 149 subjects (78%) suffering from vitamin D insufficiency (< 30 ng/ml). Vitamin D status was better in infants than in older age groups. Differences by gender were significant only in the infant age group (i.e., vitamin D status was worse among females) and were not prominent across older ages. Israelis of Ashkenazi origin had higher vitamin D mean levels than those of Sephardic origin, who, in turn, had higher vitamin D levels than Arab subjects (31.4 ± 12, 24.1 ± 10, and 17.6 ± 9 ng/ml respectively). With regard to season, there were no differences between the samples collected in winter and the samples collected in summer.

Conclusions: The results suggest that hypovitaminosis D is common across all ages, genders and seasons in Israel, a country characterized by a sunny Mediterranean climate. Specific ethnic groups may be at especially high risk.

Background: Open repair of the Achilles tendon is still the gold standard for treating rupture. This technique has the disadvantage of a long and problematic operative scar and thickly scarred Achilles tendon. To improve the surgical outcome minimally invasive techniques have been developed.

Objectives: To analyze our results of Achilles tendon repair using the Achillon® device and compare them with published studies.

Methods: We performed surgical repair of the Achilles tendon in 28 patients during a 4 year period (2004–2008): 14 patients were treated with the Achillon device, 12 with the open suture technique and 2 with the percutaneous method. Fourteen patients were available for follow-up: the tendon was repaired in 9 patients with the Achillon device, in 3 patients with open suturing and in 2 patients with the percutaneous technique. Follow-up ranged from 1 to 4 years.

Results: The average score of the AOFAS Ankle-Hindfoot Scale for the group treated with the Achillon device was 95.6 points (range 84–100) and for the group treated with the open method, 90 points (range 84–98). The length of the scar in patients operated with a minimally invasive technique was 3.81 cm (range 1–6 cm) as compared to 9.16 cm (range 8–10.5 cm) with the open suture.

Conclusions: This is the first review on this procedure in Israel. Excellent functional results were achieved with this technique. Our outcomes were similar to those of two other studies.
 

Background: According to the Israeli immunization schedule 1 year old babies should receive two concomitant vaccinations: MMR (measles-mumps-rubella), and DTap-Hib-IPV (diphtheria tetanus acellular pertussis-Haemophilus influenzae type b-poliomyelitis). However, about one-third of infants in Israel receive these vaccinations separately. Nurses at a primary care prevention clinic in Israel observed that the separate mode of vaccination is associated with a lower rate of side effects.

Objectives: To validate this observation and determine whether it represents an exception or the rule.

Methods: A nested prospective follow-up study was conducted in a primary care clinic in Israel. The survey included 191 mothers and their offspring born during 2004/2005. The mothers were interviewed over the telephone 2 weeks after the day of vaccination.

Results: The rate of adverse effects in children who received the injections separately was significantly lower than among those who were vaccinated simultaneously (40% vs. 57%).

Conclusions: It may be necessary to reconsider the current vaccination policy regarding concomitant injections.
