This expert group recommends prompt withdrawal of the culprit drug, meticulous supportive care, and judicious and early (preferably within 72 h) initiation of moderate to high doses of oral or parenteral corticosteroids (prednisolone 1-2 mg/kg/day or equivalent), tapered rapidly within 7-10 days. Cyclosporine (3-5 mg/kg/day) for 10-14 days may also be used either alone, or in combination with corticosteroids. Owing to the systemic nature of the disease, a multidisciplinary approach in the management of these patients is helpful.
Introduction:Alopecia in male is considered as a genetically determined disorder characterized by increased level of local androgen metabolite and increase androgen receptor binding in balding areas. Frequent deviations of hormones from normal values have been reported in men diagnosed with premature androgenetic alopecia (AGA) especially for androgens, gonadotropins and sex hormone binding globulin (SHBG). Different studies in the past have inferred that premature baldness before the age of thirty in males could be considered equivalent to the polycystic ovary syndrome (PCOS) in female.Materials and Methods:Hormonal profile of 50 men with severe premature balding before 30 years of age were compared with same numbers of age matched controls. The serum concentrations of total testosterone, dehydroepiandrosterone sulfate, luteinizing hormone, follicle stimulating hormone, SHBG, insulin and fasting blood sugar were estimated. Statistical analysis was performed with paired Student's t-test for cases and controls.Results:Decreased levels of SHBG with high free androgen index were found in cases when compared with the controls.Conclusion:Though altered hormonal profile may coexist in some of men with premature AGA it can’t be considered as male equivalent to PCOS in female or the metabolic syndrome.
Waldenström's macroglobulinaemia (WM) is a plasma-cell dyscrasia characterized by the monoclonal proliferation of lymphoplasmacytes. A 48-year-old man presented with a 4-year history of multiple painful, hyperkeratotic deep-seated papules over the pressure areas of both soles. He had a 1-year history of Raynaud's phenomenon, intermittent epistaxis, recurrent vomiting, tingling and numbness, and visual disturbances. Histological examination of a skin biopsy found amyloid-like deposits in the upper and mid dermis involving dermal blood vessels, but apart from periodic-acid-Schiff, various stains gave negative results for amyloid. Direct immunofluorescence was positive for IgM antibody. Hence, a diagnosis of WM with cutaneous macroglobulinosis was made. Immunoelectrophoresis found monoclonal IgM kappa antibody, and bone-marrow examination revealed a lymphoplasmacytoid malignancy. The patient's systemic systems were attributed to hyperviscosity syndrome associated with WM and the cutaneous papules were identified as deposits of excess IgM antibodies. The patient received five cycles of chemotherapy, resulting in nearly complete resolution of the skin lesions and systemic symptoms.
Causality assessment essentially means finding a causal association or relationship between a drug and drug reaction. Identifying the culprit drug or drugs can be lifesaving or helpful in preventing the further damage caused by the drug to our body systems. In dermatology practice, when it comes to cutaneous adverse drug reaction, this is much more important and relevant because many aetiologies can produce a similar cutaneous manifestation. There are multiple criteria or algorithms available as of now for establishing a causal relationship in cases of adverse drug reaction (ADR), indicating that none of them is specific or complete. Most of these causality assessment tools (CATs) use four cardinal principles of diagnosis of ADR such as temporal relationship of drug with the drug reaction, biological plausibility of the drug causing a reaction, dechallenge, and rechallenge. The present study reviews some of the established or commonly used CATs and its implications or relevance to dermatology in clinical practice.
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.
