Abstract: Pityriasis rosea (PR) is an acute, self‐limiting papulosquamous disorder of unknown etiology. Published studies of childhood PR are scarce and most are reviews. The aim of this study was to determine the demographic and clinical features of childhood PR. 相似文献

Review of 20 patients with glucocorticoid deficiency (three cases also with salt loss) associated with absent tear secretion (19 cases) and achalasia of the cardia (15 cases) revealed neurological abnormalities in 17 including hyper-reflexia, muscle weakness, dysarthria, and ataxia together with impaired intelligence and abnormal autonomic function, particularly postural hypotension. These findings indicate that significant neurological problems are common in this multisystem disorder. 相似文献

The Paced Auditory Serial Addition Task (PASAT) is a cognitive task purported to measure working memory, speed of information processing, and sustained and divided attention (Spreen, O. & Strauss, E. (1998). A compendium of neuropsychological tests: administration, norms, and commentary (2nd ed.). New York, NY: Oxford University Press.) The current study examined whether treating late responses on the PASAT as correct or as incorrect can significantly affect the outcome of the test in individuals with Multiple Sclerosis (MS). Subjects consisted of 59 individuals with MS and 37 healthy controls (HC). Scoring method was found to affect the number of individuals who were considered impaired on the PASAT. When participants were penalized for late responses significantly more participants, in both groups, were found to be impaired on the 2s trial of the task (MS: p<0.01; HC: p<0.05). Results indicate that that the specific scoring of the PASAT should be reported in studies that use the test. 相似文献

A study was performed in different areas of S?o José do Rio Preto which include the Family Health Program (FHP) and the Dengue Control Program, and the results of integration between the two programs were evaluated. In addition to other responsibilities, community health agents instructed residents on dengue control measures, encouraging the population to adopt the practices in areas with the FHP. Vector control agents were responsible for breeding site control and instructed local residents on the Dengue Control Program. From 2001 to 2003, surveys were conducted to measure residents' dengue control knowledge and practices. The proportions of residents in the FHP area that reported health services as a source of information increased significantly as compared to the other area. There were significant changes concerning the increase in information about the disease and reduction in vector breeding sites. The results show that integration between the programs is possible and could help optimize resources, avoiding duplicity of procedures and fostering greater community involvement in dengue control. 相似文献

Background and purpose:
β-Arrestins are critical scaffold proteins that shape spatiotemporal signalling from seven transmembrane domain receptors (7TMRs). Here, we study the association between neuropeptide Y (NPY) receptors and β-arrestin2, using bimolecular fluorescence complementation (BiFC) to directly report underlying protein–protein interactions.Experimental approach:
Y1 receptors were tagged with a C-terminal fragment, Yc, of yellow fluorescent protein (YFP), and β-arrestin2 fused with the complementary N-terminal fragment, Yn. After Y receptor–β-arrestin association, YFP fragment refolding to regenerate fluorescence (BiFC) was examined by confocal microscopy in transfected HEK293 cells. Y receptor/β-arrestin2 BiFC responses were also quantified by automated imaging and granularity analysis.Key results:
NPY stimulation promoted association between Y1–Yc and β-arrestin2–Yn, and the specific development of BiFC in intracellular compartments, eliminated when using non-interacting receptor and arrestin mutants. Responses developed irreversibly and were slower than for downstream Y1 receptor–YFP internalization, a consequence of delayed maturation and stability of complemented YFP. However, β-arrestin2 BiFC measurements delivered appropriate ligand pharmacology for both Y1 and Y2 receptors, and demonstrated higher affinity of Y1 compared to Y2 receptors for β-arrestin2. Receptor mutagenesis combined with β-arrestin2 BiFC revealed that alternative arrangements of Ser/Thr residues in the Y1 receptor C tail could support β-arrestin2 association, and that Y2 receptor–β-arrestin2 interaction was enhanced by the intracellular loop mutation H155P.Conclusions and implications:
The BiFC approach quantifies Y receptor ligand pharmacology focused on the β-arrestin2 pathway, and provides insight into mechanisms of β-arrestin2 recruitment by activated and phosphorylated 7TMRs, at the level of protein–protein interaction. 相似文献58.
