“…In this study, the average age for a diagnostic confirmation identified by the TRUE TEST panel, is similar to that reported in other countries such as Spain, 16 Chile, 15 and Malaysia. 17 Possible differences with other regions, 14 , 18 could be related to the fact that a considerable proportion of patients presented clinical manifestations during a specific period of time and were initially diagnosed and treated in a primary or secondary level of care, up until a partial treatment response requiring a referral to a third level of care.…”

“…The main allergens causing contact dermatitis vary depending on the region; large countries may have differences in allergens between regions 15 (see Table 2 ). However, in general terms, the major European studies described nickel, cobalt, and chromium sulfate as the main triggers.…”

“…In recent years, different regions have reported an increase in the incidence and prevalence of contact dermatitis, 10 , 11 , 12 North America reported nickel, the CI + Me-Isothiazolinone (Kathon CG), and the mixture of fragrances as the main causal agents of allergic contact dermatitis; 9 some of these agents coincide with what has been reported in Latin American studies. 13 , 14 The Latin American Region has reported a predominance in the involvement of hands, as well as a higher frequency of the condition in females 13 , 14…”

Background It is estimated that 20% of the general population is sensitized to some kind of contact allergen. Contact dermatitis is one of the major occupational diseases worldwide. This disease has a higher prevalence in the female gender and is more frequently observed in the third or fourth decade of life. The main objective of this study was to describe the main sociodemographic and clinical characteristics of patients with contact dermatitis treated in the Allergy Unit of the San Juan De Dios Hospital – Caja Costarricense de Seguro Social. Methods Clinical records of contact dermatitis outpatients from a single hospital were analyzed, in a 4-year retrospective observational study. Results At the time of the patch testing, patients showed a mean age of 42.2 years. Disease frequency was higher in the female population (female/male ratio of 4.2:1) and in patients mostly dedicated to household workchores. Most patients presented several years of disease history, and the hands were the highest affected body part. Patch testing revealed that nickel sulfate, Cl+Me-Isothiazolinone (Kathon CG), and thimerosal were allergens regularly associated with contact dermatitis in the analyzed population. Conclusions To a great extent, sociodemographic and clinical characteristics identified in these patients resemble what is reported in other regions, including the Americas and worldwide. It is worth highlighting a high female proportion rate probably related to cultural aspects, a smaller percentage of irritant contact dermatitis that may be associated to institutional patient management, and a slight difference in the most common allergens when compared to other published studies.

“…The explanation can be that the general public has become increasingly aware that offended agents such as nickel sulfate and cobalt chloride are to be avoided. In contrast, there are far more cosmetic, and odour products used in our daily life, that is making us have more reactive to these allergens [8], [9].…”

BACKGROUND:Hand eczema is a common chronic and relapsing skin disease with various clinical features. Hand eczema aetiology can be allergic contact dermatitis (ACD), irritant contact dermatitis (ICD), atopic dermatitis (AD) and unknown or combination causes. If the causative agents are not detected treatment of hand eczema will be a failure. A patch test can be useful to detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema. In Vietnam, patch test has not been used before, so we conduct this study.AIM:To identify causative allergens by using patch test with 28 standard allergens in consecutive patients.METHODS:A group of 300 HE patients from the National Hospital of Dermatology and Venereology (NHDV) in Vietnam were enrolled in this study. They were divided into 4 groups-ACD, ICD, AD and unknown aetiology. The patient was patch tested with 28 standard allergens to identify the causative agents.RESULTS:Among the 300 HE enrolled patients, ACD accounted for 72.7%, AD and ICD had the same rate of 12.7%. 39.3% of the patients had a positive patch test. Reaction to nickel sulfate was the most common (10.3%), followed by potassium dichromate (9.7%), cobalt (4%) and fragrance mix (3.1%). About one-third of the cases had relevant clinical reactions correlated with the contact agents and clinical history. Males reacted to cement, thiuram mix and formaldehyde more than females, while females reacted to a nickel more than males.CONCLUSIONS:Hand eczema has variable clinical features and diverse aetiology. ACD is an important cause of hand eczema that can be managed with a patch test to detect causative allergens. Nearly 40% of HE cases had positive patch test. Relevant patch test reactions were seen in one-third of the patients. We propose using patch test detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema.
