Background: Polymorphic Light Eruption (PLE) has been found to be associated with thyroid function abnormalities. Aim: To study and compare thyroid function tests in cases of polymorphic light eruption. Methods: The study included 35 cases of PLE and age-and sex-matched controls attending a skin outpatient department. Both cases and controls were tested for Thyroid-Stimulating Hormone (TSH). In case of abnormality in TSH, Triiodothyronine (T3) and Tetraiodothyronine (T4) levels were estimated. Results: TSH was elevated in 6 cases and 1 control. T3 and T4 were decreased in 4 cases and normal in 1 each in case and control. Hypothyroidism was seen among 6 cases and 1 control. Conclusion: Cases of PLE should be examined clinically for thyroid disorder and also tested for TSH to find any association and prevent serious consequences. % within Group 5.7% 2.9% 4.3% Total % within Group Count 35 35 70 100.0% 100.0% 100.0%Chi square-1.5, df-2, P value -0.21 (NS)
Background: Acne is a disease that affects almost 100% of the population. The clinical presentation ranges from comedones, papules, pustules and nodules. Various systemic treatment modalities like oral antibiotics, retinoids, hormonal therapy and corticosteroids, are available with varied benefits and side effects. Aims: To study and compare the efficacy and safety profile of three low dose isotretinoin regimens in the treatment of mild to moderate acne vulgaris. Methods: 75 patients having mild to moderate acne vulgaris were randomized into three different low dose isotretinoin regimens. Each was consisting of 25 patients. Group A was prescribed 5 mg, Group B 10 mg and Group C 20 mg isotretinoin for 4 months. Clinical improvement and side effects were recorded. Results: All regimens showed clinical improvement in 4 months of therapy. Isotretinoin 20 mg was found to be superior in later half of therapy. But isotretinoin 10 mg and 20 mg both were statistically equally efficacious in mild to moderate acne vulgaris. Side effects were higher in Group C as compared to Group A and B. Conclusion: We conclude that all three low dose regimens were efficacious in mild to moderate acne vulgaris. Isotretinoin 10 mg was found to be an effective and safe treatment option in such cases.
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.
