Treatment by a moisturizer of xerosis and cracks of the feet in men and women with diabetes: a randomized, double-blind, placebo-controlled study.

AIM: To evaluate a moisturizer containing urea, glycerine and petrolatum for healing deep open fissures on the feet of people with diabetes. If left untreated, open fissures, an entry point for bacteria, can lead to infection, ulceration and further complications. METHODS: This randomized, double-blind, multicentre study at 19 hospitals, general practices and diabetologists in France and Belgium included participants with diabetes and a deep open target fissure on their heel. Participants were randomized to test cream or placebo (1 : 1) for 4 weeks. Complete target fissure healing after 4 weeks (primary criterion) and 2 weeks, target fissure closure, overall fissure healing and xerosis were assessed. RESULTS: Some 167 participants were randomized (80 to test cream; 87 to placebo); all were included in the efficacy analyses. The percentage of participants with complete target fissure healing after 4 weeks was higher with test cream than placebo (46.3% vs. 33.3%): the difference did not reach statistical significance (P = 0.088). Fewer participants still had a deep open target fissure with test cream than placebo, the difference was statistically significant and clinically relevant after 2 (24.7% vs. 42.7%, P = 0.027) and 4 weeks (6.4% vs. 24.1%, P = 0.002). The difference in overall fissure healing between test cream and placebo was significant (P < 0.001) and test cream resulted in greater xerosis improvement (P < 0.001 and P = 0.002 at 2 and 4 weeks, respectively). CONCLUSION: The activity of the test cream for treating feet fissures of people with diabetes was confirmed by an improvement in open fissure healing and xerosis. The cream was well tolerated.

Eau thermale d'Avène et dermatite atopique: Avène's thermal water and atopic dermatitis.

Atopic dermatitis (AD) is the most frequent disease treated at the Avène hydrotherapy center. Children represent a large part of the population due to the high prevalence of AD in early childhood. Avène thermal spring water (ATSW) has been known for its therapeutic effects since the middle of the 18th century. It has been greatly studied over the last decades, with a comprehensive fundamental, pharmaco-clinical and clinical approach. Cohort studies using the Scoring Atopic Dermatitis (SCORAD) clinical score and the Dermatology Life Quality Index (DLQI) or the Children's Dermatology Life Quality Index [CDLQI]) quality of life scores, allowed to confirm the clinical results obtained from the previous studies. These results were corroborated by clinical trials conducted in atopic patients outside the Avène hydrotherapy center, allowing to demonstrate the specific effect of the ATSW. Pharmacological and pharmaco-clinical studies evidenced several effects that could explain the healing effect of ATSW: effect on histamine release, anti-inflammatory effects on standardized models, immuno-modulation of some cytokines involved in DA physiopathology (interferon [INF], interleukin 2 and 4 [IL-2, IL-4]), improvement of keratinocyte differentiation, effect on the skin microbioma by promoting the development of a diversified non-pathogenic flora. In addition, an original microorganism, Aquaphilus dolomiae, never described in another medium, has very recently been identified in the ATSW. Aquaphilus dolomiae is responsible for significant pharmacological activities on inflammation, pruritus and enhancement of innate immunity. This set of works confirms the medical significance of the hydrotherapy which should be considered as a complementary care in the sometimes difficult management of AD.

[General practice management of obstructive sleep apnea in the Midi-Pyrénées]. / Prise en charge du syndrome d'apnées obstructives du sommeil en médecine générale en Midi-Pyrénées.

INTRODUCTION: Obstructive sleep apnoea syndrome (OSAS) is a significant public health problem. In the French care system general practitioners have an important role to play in its management especially in the field of early diagnosis. METHODS: The first part of this work is a descriptive case-control study looking at health resource usage of OSAS patients treated with continuous positive airway pressure (CPAP) in the MidiPyrénées area. The second part is a descriptive study which involved by interviewing 100 general practitioners settled in the area in order to evaluate their knowledge and their practice regarding OSAS. Results were compared with a previous study (1) performed in 2002 with similar methodology. RESULTS: Our results confirm that OSAS remains to a large extent undiagnosed (mean OSAS patients was less than 6 per physician) and underline the close connection between OSAS and cardiovascular diseases. A low degree of knowledge concerning the symptoms, main complications and treatment of OSAS was observed in this group of physicians. There was, however a relative improvement in the answers compared to the study performed in 2002. Two or more complications were mentioned by 67% of practitioners (33% in 2002) and only 13% of them were unable to identify at least one possible complication of OSAS (50% in 2002). CONCLUSION: This study confirms the impact on health of OSAS, characterized by a higher consumption of various medications than in non OSAS patients. Knowledge of OSAS remains low in general practitioner population in France. An important effort has to be made to improve learning of this disease by continuous medical training and during initial medical course.

Nutritional intake and recreational physical activity in healthy elderly women living in the community.

PURPOSE: Recreational physical activity, which increases energy expenditure, may help to maintain proper food intake. To compare the nutritional intake of inactive, active and very active healthy elderly women. METHODS: Eighty-two women were recruited in the community. Participants had to be > or = 65 years and in good health (< or = 2 drugs, < or = 1 major illness, < or = 1 surgical operation, no disability in basic or instrumental activities of daily living and no cognitive impairment). We compared food intakes between the 26 inactive (age 73.9 +/- 7.7 y, BMI 24.3 +/- 3.2 kg/m2), the 29 active (age 71.5 +/- 5.6 y, BMI 23.2 +/- 3.5 kg/m2) and the 27 very active (age 70.9 +/- 4.8 y, BMI 24.3 +/- 3.2 kg/m2) healthy women. The nutritional intake was evaluated by a three-day food record. Macronutrient, mineral and vitamin content were derived from tables. Self-reported type, duration and frequency of recreational physical activities during the last month were converted into energy expenditures. RESULTS: Despite high levels of energy intake (mean 1743.9 kcal/d), mean intakes of calcium, vitamin B1, E and folic acid were lower than Recommended Dietary Allowances (-26.2%, -12%, -50.8%, -2.4% respectively) in the whole sample. There were no significant differences of energy intake and quantities of nutrients between the groups except for calcium intake which was significantly higher in inactive women (p=0.04). CONCLUSION: Active healthy elderly women do not have a better nutritional profile than their inactive peers.

Evaluation of the moisturizer Pédimed(®) in the foot care of diabetic patients.

AIM: Xerosis is one of the most common abnormalities observed in the diabetic foot, promoting ulceration through the development of fissures and hyperkeratosis. Its treatment is therefore paramount and must be implemented early on. The objective of this study was to assess the moisturizing properties of Pédimed(®) cream in the treatment of foot xerosis in diabetic patients. METHODS: In this randomized double-blind study, Pédimed(®) and its placebo were randomly allocated to the right/left foot of each patient (one active/one control side). Products were applied twice daily for 4 weeks. Xerosis was assessed using the clinical Xerosis Assessment Scale (XAS), corneometry (skin hydration measurement) and D-Squame(®) (scale sample analysis) after 14 (D14) and 28 (D28) days of treatment. RESULTS: Twenty-four men and 30 women, aged 57.0±12.7 years, with type 1 or type 2 diabetes and moderate-to-severe foot xerosis were included. A dramatic decrease in XAS score that was more marked with Pédimed(®) than with placebo was observed from D14 (38.1% vs 20.9%, P<0.0001), reaching 61.9% vs 34.9% at D28 (P<0.0001). The number of feet with fissures was greatly reduced with Pédimed(®) compared with placebo at both D14 (11.1% vs 22.2%, P=0.031) and D28 (5.6% vs 18.5%, P=0.039). Skin hydration increased by 48.9% with Pédimed(®) vs 31.7% with placebo at D14 (P=0.0002), reaching 57.3% vs 36.5% at D28 (P<0.0001). All D-Squame(®) parameters showed greater improvement with Pédimed(®). Product tolerability was excellent. CONCLUSION: Validated clinical and paraclinical tools demonstrated the efficacy of Pédimed(®) in improving xerosis and reducing fissures of the feet in diabetic patients.
