The epidemiology and outcome of rosacea among local patients were studied. Rosacea is more common among certain racial groups such as Chinese, Caucasian, and other races. The clinical subtypes also seem to be related to races of certain skin colors and might be related to varied natural intrinsic responses to the sun among different racial groups.
We report an unusual case of drug-associated granulomatous CD30 + T-cell pseudolymphoma secondary to amlodipine. A 55-year-old Chinese man presented with a 6-month eruption of disseminated erythematous dermal papulonodules and annular infiltrated plaques over his neck and limbs symmetrically. Histopathology revealed a perivascular and interstitial infiltrate of histiocytes, eosinophils and morphologically normal lymphocytes associated with CD30 expression. The eruption improved rapidly after discontinuation of amlodipine and did not recur.
Introduction: Sun exposure increases skin cancer risk. Studies have shown that demographic factors influence sun safety behaviour but there is a paucity of such data in Singapore. We aimed to identify sociodemographic predictors of sun safety habits in Singapore. Materials and Methods: A total of 2328 adults participated in a cross-sectional survey on time spent under the sun and sun safety habits (using protective headgear, body attire, umbrellas and sunscreens). A composite Sun Protection Score (higher scores represented better habits [range, 0–15]) and the average daily hours (ADH) of sun exposure were derived from the data. The relationship between the Sun Protection Score and ADH of sun exposure with sociodemographic factors was analysed using univariate (Mann-Whitney U or Kruskal-Wallis tests), multiple linear and logistic regression analyses. Results: The following statistically significant variables predicted a lower Sun Protection Score: men (β = -1.48, P <0.001), Indians (β = -1.04, P <0.001), history of diabetes (β = -0.60, P = 0.007) and people who do not consume alcohol (β = 0.31, P = 0.03). Younger adults (β = -0.2, P <0.001), men (β = 0.80, P <0.001), darker skin type (β = 0.27, P <0.001) and lower education level (β = -0.18, P <0.001) were statistically significant variables that predicted a longer ADH of sun exposure. Conclusion: The study has identified sociodemographic predictors of sun safety habits in Singapore.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
