1/7. cheilitis caused by contact urticaria to mint flavoured toothpaste.A 26-year-old woman presented with a 12-month history of persistent dermatitis of the lips. She had failed to respond to cosmetic avoidance and therapeutic measures. Patch testing was negative, including her toothpaste and toothpaste flavours. She defied diagnosis until an acute flare followed immediately after dental treatment with a mint flavoured tooth cleaning powder. This led us to prick test her to mint leaves and this was positive. Her cheilitis settled after changing from her mint-flavoured toothpaste. A diagnosis of contact urticaria should be considered in cases of cheilitis of unknown cause.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
2/7. Actinic prurigo, tropical (South-East Asian) variant.Actinic prurigo is a chronic familial photodermatitis found predominantly among the Amerindians. It has been reported from North and south america, Britain and japan. We report a case of actinic prurigo seen in singapore. A 20-year-old Malay female presented with a persistent pruriginous eruption in the sun-exposed parts and on her abdomen. She also had lower lip cheilitis and thinning of the outer eyebrows, features often seen in actinic prurigo. The minimal erythema dose to ultraviolet A (UVA) and UVB were persistently lowered. We propose that this condition be called actinic prurigo, tropical (South-East Asian) variant.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
3/7. acrodermatitis enteropathica in saudi arabia.Four patients with acrodermatitis enteropathica (AE) are presented from three Saudi families. The clinical picture in these patients is basically similar to that described elsewhere. These patients, however, showed different degrees of involvement of various body systems. In all cases, low serum zinc levels were documented, and they responded well to zinc supplementation. In the follow-up evaluation, angular cheilitis was observed as a feature that appears to herald the relapse of disease. Interestingly, when patients are treated, it was the last sign to disappear. Current information on zinc is summarized.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
4/7. Actinic prurigo of the lower lip. review of the literature and report of five cases.Actinic prurigo (AP) is a chronic, familial, photodermatitis that primarily affects American Indians. It is more prevalent in young females and may be evident clinically as a pruritic lower lip cheilitis that typically does not respond to conventional therapy. Other clinical features associated with AP include conjunctivitis, alopecia of the eyebrows, and formation of pterygia. The histologic features of AP have been described as nonspecific. We are presenting five cases of AP in which the major clinical manifestation was a pruritic, unsightly lower lip cheilitis. All of our patients were American Indians. Three patients were from the same family. The youngest patient was 10 years old and the oldest was 69 years old. All five cases were characterized histologically by numerous germinal centers within the lamina propria and a dense perivascular plasma cell infiltrate. In four of the five cases, there was a moderate to dense infiltrate of eosinophils. All five patients had been generally unresponsive to conventional therapy. With the exception of the youngest patient, all had had the disease for at least several years. One patient, now deceased, had the lower lip lesion surgically removed for cosmetic reasons. To our knowledge, this is the first report in the dental literature that describes the clinical and histologic features of AP of lower lip.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
5/7. Lipstick dermatitis due to C18 aliphatic compounds.An 18-year-old girl developed cheilitis. She had a past history of lip cream dermatitis, but the cause was not found. patch tests with 2 lipsticks were strongly positive. Tests with the ingredients were positive to 2 aliphatic compounds, glyceryl diisostearate and diisostearyl malate. Impurities in the materials were suspected as the cause. Analysis by gas chromatography detected 3 chemicals in glyceryl diisostearate and 1 in diisostearyl malate as impurities. Patch testing with the impurities and glyceryl monoisostearate 0.01% pet in glyceryl diisostearate and isostearyl alcohol 0.25% pet in diisostearyl malate were strongly positive. The characteristics common to the 2 chemicals were liquidity at room temperature, branched C18 aliphatic compound and primary alcohol. Chemicals lacking any of the above 3 features did not react.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
6/7. No evidence of contact sensitization to acyclovir in acute dermatitis of the lips following local application of Zovirax cream.We report 4 patients with acute contact dermatitis of the lips following application of Zovirax cream. patch tests with pure acyclovir, and combinations of the ingredients of the cream base, with and without acyclovir, provided no evidence of sensitization to any constituents of the cream.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
7/7. Methylmalonic acidemia, cobalamin C type, presenting with cutaneous manifestations.BACKGROUND: Erosive dermatitis resembling the skin lesions of acrodermatitis enteropathica has been described in a number of aminoacidopathies and organic acidemias. In some, the dermatitis is a manifestation of untreated disease, while in others, including methylmalonic acidemia, skin lesions have been ascribed to nutritional deficiency due to therapeutic amino acid restrictions. OBSERVATIONS: We report 2 cases of methylmalonic acidemia presenting with cutaneous manifestations in the perinatal period before restrictive nutritional interventions. The cutaneous involvement consisted of cheilitis and diffuse erythema with erosions and desquamation. Methylmalonic acidemia, cobalamin C type, was subsequently diagnosed in both cases. CONCLUSIONS: An erosive, desquamating dermatitis with histopathologic characteristics resembling acrodermatitis enteropathica may be a presenting sign in cobalamin C methylmalonic acidemia, even in the absence of long-standing nutritional restrictions or deficiency.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
