Abstract
The sesquiterpene lactones (SLs) are secondary plant metabolites, which are widespread in the Compositae/Asteraceae plant family. The first SLs were detected more than 100 years ago, and allergic contact dermatitis from Compositae has been reported since the beginning of the 1900s, but it was not until the late 1960s and early 1970s that a collaboration between dermatologists, chemists and botanists led to the detection of SLs as the main allergens of Compositae plants. In the 1980s, the SL mix, consisting of equimolar amounts of alantolactone, costunolide and dehydrocostus lactone, was developed as a screening agent for Compositae sensitisation. Today, after inclusion of SL mix in the baseline series, the mean prevalence of reactions in Europe is around 1%, and in North America 0.8%. In countries outside Europe and North America, the prevalence ranges between 0% and 10.7%. The detection rate of SL mix is lower than that of some plant extracts, and ideally, SL mix should be supplemented with a mix of SLs from locally prevalent allergenic plants. The prevalence of positive reactions to SL mix suggests continued baseline testing in most European countries, North America, New Zealand, Australia and probably some Chinese centres.

Abstract
BACKGROUND Hand dermatitis (HD) is inflammation of the skin of the hands. It ranges in severity and has a significant impact on quality of life (QoL). The physical and psychosocial burden of the disease is comparable with psoriasis in impairment of the QoL of the patient and depression. Quality of life correlates with disease severity. AIM To evaluate the management outcome of HD with a disease severity tool by the physician and quality of life index. MATERIALS AND METHODS This was a cross-sectional study of a cohort of patients with HD over 24 weeks in the dermatology clinic of a tertiary hospital in Nigeria. Disease severity and quality of life were measured using the physician global assessment (PGA) and dermatology life quality index (DLQI), respectively. These were re-administered 6 weeks after treatment. Results were collated and analyzed. RESULTS One hundred and seventy-seven (13.3%) of 1,329 patients had HD with F/M ratio of 1.2: 1; a mean age of 34.6 ± 7.4 years. Comparing PGA scores at baseline and 6 weeks, a statistically significant improvement was noted P < 0.001. The mean DLQI score at baseline was 10.38 and reduced to 3.02 post-treatment. The difference between the two means of the DLQI was ≥5 from baseline signifying improved quality of life. The domain of symptoms and feelings was the most affected at baseline and most improved afterward. CONCLUSION HD has a significant impact on its sufferers and this correlates with disease severity. Appropriate management improves disease outcome and patients' quality of life.

Abstract
Abstract
As other causes decline in importance, chromium-tanned leather has become a more important source for chromium allergy, which affects around 1% of the general population. The aim of this review is to give suggestions on how to minimize the risk of leather-related allergic contact dermatitis, which can be elicited in chromium-allergic persons by hexavalent and trivalent chromium released from leather. Hexavalent chromium is the more potent chromium form and requires a lower skin dose to elicit allergic reactions. It is formed on the surface of some, antioxidant-free, leathers at dry conditions (< 35% relative humidity) and is influenced by the tanning process and other conditions, such as UV irradiation, contact with alkaline solutions, and leather age. Trivalent chromium is the dominant form released from chromium-tanned leather and its released amount is sufficient to elicit allergic reactions in some chromium-allergic individuals when they are exposed repetitively and over longer time (days – months). A low initial test result (< 3 mg/kg) for hexavalent chromium with the current standard test (ISO 17075) does not guarantee a low release of chromium from the leather or a low release of hexavalent chromium under typical exposure conditions during the service life of the leather. Information, labels, and certificates regarding leather products are often insufficient to protect chromium-allergic individuals. Correct labelling and information on the possible content of different allergens, as well as different tanning alternatives for certain leather products, are crucial.

Abstract
Objectives: Sensitization of allergens varies among societies and also it is influenced by various factors, such as age and gender. It may even change over the years. In this study, we aimed to evaluate the patch test results in patients with contact dermatitis (CD) in our center. Methods: European standard series patch test results of patients with CD between 2017 and 2018 were evaluated retrospectively. Results: Of the 135 patients, 65 (48.1%) were males, 70 (51.9%) were females. The mean age of patients was 41.43±14.26 (11-78) years. In 78 (57.8%) patients, a positive reaction against at least one allergen was detected. The most common allergens were nickel sulfate (27.4%), potassium dichromate (14.8%), cobalt chloride (11.9%), textile dye mix (8.1%), fragrance mix i, ii (6.7%) and balsam of Peru (4.4%). The sensitization of nickel sulfate was higher in females and sensitization of cobalt chloride and potassium dichromate in males (p=0.03, 0.05, 0.03, respectively). In the multivariate logistic regression analysis, age was independently related to a positive reaction against at least one allergen. Conclusion: Nickel sulfate, potassium dichromate, cobalt chloride and textile dye mix were the most common allergens. Legal regulations should be made to decrease exposure to allergens.

Clinico-etiologic profile of hand dermatitis and patch response of patients at a tertiary hospital in Lagos, Nigeria: results of a prospective observational study. Int J Dermatol 2018; 57:149-155.

Abstract
BACKGROUND Hand dermatitis is an acute or chronic inflammation of the skin of the hands from a multifactorial cause which may be endogenous, exogenous, or a combination of both. With a wide range in severity and recurrent periods of flares, it has significant impact on the quality of life of its sufferers. A history of atopy predisposes patients to hand dermatitis, but contact dermatitis, either allergic or irritant, is the more commonly implicated factor in the etiology of hand dermatitis. Patch testing is an important tool in identifying the allergen responsible for allergic hand dermatitis, and this knowledge will contribute to improved management. AIM AND OBJECTIVES This study was undertaken to evaluate the clinical and etiologic profile and review the patch responses of patients who presented with hand dermatitis at a foremost tertiary skin clinic in the most populous state of the most populous country in Africa. METHODS A prospective, observational study in which consecutive walk-in patients who fulfilled the inclusion criteria were enrolled. Ethical clearance was obtained. Study tools included self-administered questionnaires, physical examination, and patch tests (European Hermal series), amongst others. The patch tests were carried out. Results were documented, and treatment was individualized based on clinical and investigation findings. The results were collated and analyzed with SPSS® 17.0 edition (SPSS II). RESULTS Hand dermatitis was seen in 177 (13.3%) patients who presented during the study period. The mean age was 34.6 + 17.4 years. Almost two-thirds of patients (119; 67.2%) had chronic hand dermatitis, while 53 (32.8%) presented acutely. Patch responses were positive in 65 (36.7%) patients with paraphenylenediamine identified as the most frequent cause. Respondents had at least one (+) response to 20 of the 28 allergens, while there was no response to eight of the allergens in the European series. CONCLUSION The study reveals that hand dermatitis is present in a younger age group and a variety of subtypes coexist. Locally sourced allergens are needed to improve the yield of patch responses.

Abstract
Background and Aim. Contact dermatitis (CD) is the most prevalent occupational skin disease with a significant impact on quality of life. Patch testing is used for the identification of responsible allergens which may improve protective and preventive measures in the workplace. Herein, we aim to identify the demographic characteristics and occupation of patients with early diagnosis of occupational CD and compare patch test results. Materials and Methods. The study included 330 patients referred to our clinic between April 2009 and April 2011 and who were patch-tested with 28-allergen European Standard Test. Results. 126 (38%) patients were female and 204 (62%) were male with a mean age of 36.12 (±13.13) years. Positive allergic reactions were observed in 182 (55%) patients. Nickel sulphate (41/126) and potassium dichromate (39/204) were significantly the most common allergens in women and men, respectively (P < 0.005). Additionally, the most common occupation in women was household activities (83/126) and in men was manufacturing (80/204). Conclusion. The allergens to which people become sensitized differ according to their working environment and occupation. Classification of occupations is important for identification of sensitization risks and monitoring of changes in allergen distribution of different occupations.
