SUMMARYThe objective is to assess the influence of sociodemographic, professional and clinical variables on the choice of treatment of work-related carpal tunnel syndrome (CTS). An exhaustive and trans-sectional study was conducted over a period of eight years, from 1st January 2006 to 31 December 2013 in the Department of Occupational Medicine at University Hospital of Mahdia, Tunisia. The study population was represented by patients with work-related carpal tunnel syndrome. Data collection was based on a questionnaire sheet, describing social, occupational and medical characteristics of patients. The study population was characterized by a large female dominance, representing 95.3% with an average age of 42±7.8 years. Patients medically treated represented 38.7% and 61.3% had had surgical treatment. After binary logistic regression, surgical indication of CTS was significantly correlated to diabetes (p=0.017), other musculoskeletal disorders (p=0.02), functional signs of CTS (acrocyanosis p=0.05; muscle weakness p=0.015; radiating pain p=0.01; painful discomfort of the hand, the forearm or arm p=0.027) and to the atrophy of thenar muscles (p=0.018). According to this study, the choice of therapy for occupational CTS depends only on clinical data. More detailed studies will be needed to refine these results.

Amaç: Yama test sonuçları üzerinde yaşın etkisini incelemek ve yaş gruplarına göre deri duyarlaştırıcılarının profillerini karşılaştırmaktır. Yöntemler: Bu sekiz yıllık retrospektif çalışma, Tunus, Sousse Üniversite Hastanesi, Meslek Hekimliği Bölümü, Dermatoloji ve Alergoloji Ünitesi'nde alerjik kontakt dermatit hastalarının tüm tıbbi kayıtlarını içermektedir. Çalışma popülasyonu iki yaş grubuna ayrıldı (grup 1: <40 yaş hastalar; grup 2: >40 yaş hastalar). İstatistiksel anlamlılık derecesi p<0,05 olarak kabul edildi. Bulgular: Beş yüz altmış sekiz hasta en az bir yama testine pozitif reaksiyon vermiştir. Yaşlı bireylerin en az bir yama testine pozitif yanıt vermeleri gençlere göre 1,1 kat daha muhtemeldir. İki grupta da görülen en yaygın alerjenler: potasyum dikromat (%34,2, %38), tiuram karışımı (%6, %11), kobalt klorür (%27, %28,8), Peru balsamı (%6, %11,3) ve nikel sülfattır (%41, %27,3). Potasyum dikromat ile deri reaksiyonlarının intansitelerinde belirgin bir varyasyon not edildi (p=0,00). Sonuç: Yama test sonuçları üzerinde yaş etkisinin fizyolojik mekanizmasının aydınlığa kavuşturulması ve European Standard Battery'yi alerji tipi ve uygun konsantrasyonlar açısından her yaş grubuna uyarlamak için daha fazla çalışmaya gereksinim vardır.

Methods: It is an 8-year retrospective study involving entire medical records of the patients with allergic contact dermatitis at the Unity of Dermatology and Allergology in the Department of Occupational Medicine, University Hospital of Sousse in Tunisia. Study population was divided into two age groups (group 1: patients <40 years; group 2: patients >40 years). The statistical significance level was taken as p<0.05. Results: Among the patients, 586 have had at least one positive reaction to the patchtest. Older individuals were 1.1 times more likely to have at least one positive reaction to the patch-test than younger ones. The most common allergens in both groups are potassium dichromate (34.2% vs. 38%), thiuram mix (6% vs. 11%), cobalt chloride (27% vs. 28.8%), balsam of Peru (6% vs. 11.3%) and nickel sulphate (41% vs. 27.3%). A significant variation was noted for potassium dichromate in terms of intensity of skin reaction (p=0.00). Conclusion: More research is needed to elucidate the physiologic mechanisms of age on the patch-test results and to adapt the European Standard Battery to each age group in term of allergen type and their appropriate concentration.
