Introduction: Leprosy is a chronic disease that affects skin and peripheral nerves. Disease complications include reactional episodes and physical impairment. One World Health Organization (WHO) goal of leprosy programs is to decrease the number of grade 2 impairment diagnoses by 2015. This study aims to evaluate clinical factors associated with the occurrence of leprosy reactions and physical impairment in leprosy patients. Methods: We conducted a retrospective study of data from medical records of patients followed in two important centers for the treatment of leprosy in Aracaju, Sergipe, Brazil, from 2005 to 2011. We used the chi-square test to analyze associations between the following categorical variables: gender, age, operational classifi cation, clinical forms, leprosy reactions, corticosteroid treatment, and physical impairment at the diagnosis and after cure. Clinical variables associated with multibacillary leprosy and/or reactional episodes and the presence of any grade of physical impairment after cure were evaluated using the logistic regression model. Results: We found that men were more affected by multibacillary forms, reactional episodes, and grade 2 physical impairment at diagnosis. Leprosy reactions were detected in a total of 40% of patients and all were treated with corticosteroids. However, physical impairment was observed in 29.8% of the patients analyzed at the end of the treatment and our multivariate analysis associated a low dose and short period of corticosteroid treatment with persistence of physical impairments. Conclusions: Physical impairment should receive an increased attention before and after treatment, and adequate treatment should be emphasized.
The objective of this study was to investigate whether red cell indices mean cell volume (MCV) and mean cell haemoglobin (MCH) were lower in frequent blood donors and hence, indirectly, able to predict impending iron depletion. Serum ferritin and/or soluble transferrin receptor levels can be used to evaluate iron status but are not practical for routinely screening blood donors prior to donation. Hb, MCV and MCH were measured on venous blood from 886 blood donors using a Sysmex E-5000. Full details were obtained for all donors of each earlier donation over the previous 3 years. MCV and MCH levels were lowest in donors with the highest frequency of previous blood donation. There was a significant negative correlation between MCV and number of donations in males and females and between MCH and number of donations in females, over the 3 year period 1995-97. Similar trends were observed when only the previous year's donations (1997) were considered with all categories showing significant negative correlations and additionally, Hb levels in females showed negative correlation with number of donations in 1997. In conclusion, increased frequency of blood donations is associated with lower MCV and MCH. These red cell indices, or more sophisticated parameters such as percentage hypochromic cells, should be used to monitor early onset of iron depletion in frequent blood donors.
Ostraceous psoriasis is a rare form of psoriasis, characterized by lesions with firmly adhered thick scales, in various colors, with surfaces resembling oysters shells. The protracted course of clinical presentation allied with peculiar lesions and histopathological examination permit the diagnosis. Lesions are usually resistant to topical medications, requiring systemic treatment. It is important that dermatologists are able to diagnose the unusual forms of psoriasis to avoid iatrogeny. We report the case of a patient with ostraceous psoriasis treated with methotrexate.
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.
