Correlation of nipple eczema in pregnancy with atopic dermatitis in Northern India: a study of 100 cases.

BACKGROUND: Nipple eczema is a less common presentation of atopic dermatitis. No studies in the literature have correlated nipple eczema in pregnancy as a manifestation of atopic dermatitis. OBJECTIVE: To evaluate whether nipple eczema presenting in pregnancy is a manifestation of atopic dermatitis. METHODS: This was a prospective observational study including 100 women who presented with nipple eczema for the first time during pregnancy. The exclusion criteria were any patient with previous history of nipple eczema, those already on oral or topical treatment for atopic dermatitis or nipple eczema, and other disorders mimicking eczema. Patients were divided into two groups ‒ nipple eczema with atopic dermatitis and without atopic dermatitis. Demographic data, clinical features, total leukocyte count, differential leukocyte count, absolute eosinophil counts, and serum IgE levels were compared between the two groups to detect association between nipple eczema in pregnancy and atopic dermatitis. RESULTS: Out of 100 patients, 39 were diagnosed with atopic dermatitis, whereas 61 were ruled out to have any features suggestive of atopic dermatitis. There were no statistically significant differences in mean age, mean duration of symptoms, and serum IgE levels. In patients with atopic dermatitis, bilateral symptoms were noted more commonly than in patients without the disease, but this was statistically insignificant. STUDY LIMITATIONS: Lack of long term follow-up and no large studies in literature to compare results. CONCLUSION: Nipple eczema in pregnancy follows a similar pattern as in other age groups. The clinical profile of patients is similar in cases with and without atopic dermatitis.

Expression of heat shock and cold shock proteins in the gorgonian Leptogorgia virgulata.

In this study, we analyzed the response of the temperate, shallow-water gorgonian, Leptogorgia virgulata, to temperature stress. Proteins were pulse labeled with (35)S-methionine/cysteine for 1 h to 2 h at 22 degrees C (control), or 38 degrees C, or for 4 h at 12.5 degrees C. Heat shock induced synthesis of unique proteins of 112, 89, and 74 kDa, with 102, 98 and 56 kDa proteins present in the control as well. Cold shock from 22 degrees C-12.5 degrees C induced the synthesis of a 25 kDa protein, with a 44 kDa protein present in the control as well. Control samples expressed unique proteins of 38, and 33 kDa. Non-radioactive proteins expressed under the same conditions as above, as well as natural field conditions, were tested for reactivity with antibodies to heat shock proteins (HSPs). HSP60 was the major protein found in L. virgulata. Although HSP47, HSP60, and HSP104 were present in all samples, the expression of HSP60 was enhanced in heat stressed colonies, while HSP47 and HSP104 expression were greatest in cold shocked samples. Inducible HSP70 was expressed in cold-shocked, heat-shocked, and field samples. Constitutively expressed HSP70 was absent from all samples. The expression of HSP90 was limited to heat shocked colonies. The expression of both HSP70 and HSP104 suggests that the organism may also develop a stress tolerance response.
