ABSTRACT
Tinea of vellus hair is caused by dermatophyte infection of vellus hairs, and commonly affects children. It usually occurs on the face, and clinically manifests as annular or semi-annular erythema gradually spreading to the surrounding area, with central clearing and a slightly elevating border covered with papules and papulovesicles. Intense inflammation, which may manifest as pustules, erosions, exudation, scales and crusts, can be observed in patients with severe tinea of vellus hair. Direct microscopy of fungi showed abundant hyphae and/or spores on vellus hairs. Topical antifungal therapy is usually ineffective, and systemic antifungal therapy should be considered. In order to reduce the high rate of missed diagnosis and misdiagnosis, and to improve clinicians′ understanding of this disease, this review summarizes the incidence, clinical manifestations, diagnosis and treatment of tinea of vellus hair.
ABSTRACT
Objective To explore the value of simple exercise provocation test ( 6?minute running test) combined with small airway function test in early diagnosis of cough variant asthma ( CVA ) in children.Methods Ninety?four children with chronic cough from September 2017 to September 2018 in the pediatric clinic of the Affiliated Hospital of Xuzhou Medical University were selected for routine pulmonary ventilation function examination,simple exercise stimulation test and questionnaire survey.The differences of pulmonary function,clinical manifestations and allergens between positive and negative children with simple exercise stimulation test were compared and analyzed.Results The forced expiratory volume in one second (FEV1) of 94 children with chronic cough were all more than 70% by routine pulmonary function test,and the exercise provocation test was successfully completed.Among them,32 (34.04%) were positive in simple exercise provocation test.Among the positive patients,30 cases ( 93.75%) were diagnosed as CVA after further examination,clinical treatment and follow?up.In CVA group, FEV1 ( 81.52 ± 14.22)%,forced vital capacity (FVC) (89.00 ± 14.31)%, peak expiratory flow ( PEF) ( 65.05 ± 15.10)%, one?second rate (FEV1／FVC) (92.18±13.59)%,and instantaneous flow at 50% forced expiratory flow were observed after exercise.The vital capacity ( FEF50 ) ( 57.57 ± 22.49 )%, forced expiratory flow at 75% vital capacity (FEF75) (41.15±18.28)%,maximum expiratory flow ( MMEF75／25) (53.14±22.53)% were significantly lower than those before exercise ((94.07±9.69)%,( 92.30± 13.60)%,(80.73± 17.85)%,(101.07± 13.79)%,(66.71±19.29)%,(51.32±18.38)%,(63.75±19.43)%),(t values were 8.592 ,2.617 , 10.246 ,5.428,3.590 ,3.646 ,3.687 ,respectively,all P＜0.05)) In routine examination of pulmonary ventilation function,FEF50 (66.71 ± 19.29)% and FEF75 ( 51.32 ± 18.38)% in the positive group were significantly lower than those in the negative group (( 79.75 ± 21.94)%、( 69.08 ± 29.28)%),( t values were －2.841,－3.123,all P＜0.01).The proportion of night cough,morning cough and severe dry cough in positive group was significantly higher than that in negative group,while the proportion of day cough and wet cough was significantly lower than that in negative group ( P＜0.01).The proportion of eczema history in positive group was significantly higher than that in negative group ( P＜0.01).Conclusion Patients with CVA have high airway responsiveness and small airway dysfunction.Combination of simple motor stimulation test and small airway function test has important clinical value in the early diagnosis of CVA.
ABSTRACT
Objective To analyze the effect of Huashi Xingyu Qingre decoction therapy through identification of the differentially expressed saliva proteins of oral lichen planus. Method The saliva of OLP patients before and after treatment were collected. Total saliva proteins were extracted. The differentially expressed saliva proteins were screened by two-dimensional fluorescence difference gel electrophoresis and identified by liquid chromatography-mass spectrometry. The differentially expressed proteins were analyzed by Western-blot. Results Six differentially expressed proteins were identified as salivary amylase, serum albumin, IgM, carbonic anhydrase VI, zinc-α2- glycoprote and sIgA. The expression level of serum albumin, IgM, carbonic anhydrase VI and zinc-α2-glycoprotein after treatment were lower than that before. However, the expression level of sIgA was higher. The differences were statistically significant. Conclusions Some differentially expressed saliva proteins of OLP before and after Huashi Xingyu Qingre decoction therapy are characterized, and they may play a vital part in the occurrence and development of OLP.
ABSTRACT
Objective Oral lichen planus ( OLP) is a common complaint in the oral mucosa , for which there is no definite therapy hitherto.This article aimed to investigate the possible effect of Huashi Xingyu Qingre Decoction (HXQD) on OLP. Methods This study included 30 randomly selected cases of OLP treated with HXQD .Fasting venous blood and total serum protein were obtained before and after medication for screening and identification of OLP-related differential proteins by two-dimensional fluorescence differ-ence gel electrophoresis (2D DIGE) and liquid chromatography-mass spectrometry (LC-MS), followed by Western blot validation . Results Haptoglobin , antithrombin Ⅲ, C1 complement , and vitamin D binding protein were differentially expressed in the serum of the OLP patients before and after treated with HXQD .Compared with the baseline , the expression of haptoglobin was significantly in-creased (103.086 ±27.536 vs 159.704 ±24.228, P<0.05) while that of antithrombin Ⅲ remarkably decreased after treatment (150.00 ±54.04 vs 98.00 ±28.04, P<0.05). Conclusion Haptoglobin, antithrombin Ⅲ, C1 complement, and vitamin D binding protein are differentially expressed in the serum of OLP patients before and after HXQD medication , which may be associated with the development and progression of OLP .
ABSTRACT
ObjectiveTo explore the potential hazards and preventive measures in patients with dysphagia after brain stem infarction.Methods Seventy-eight patients with dysphagia after brain stem infarction were divided into indwelling gastric canal group(57 cases) and none-indwelling gastric canal group(21 cases).The pulmonary infection,respiratory tract obstruction,alimentary tract hemorrhage and deglutition function recovery were compared between the two groups.Results The rate of pulmonaryinfection in indwelling gastric canal group was significantly lower than that in none-indwelling gastric canal group [26.3％ (15/57) vs.81.0％ (17/21),P ＜ 0.01 ].The weight in indwelling gastric canal group was significantly higher than that in none-indwelling gastric canal group [ (65.3 ± 13.5 ) kg vs.(56.2 ± 13.2) kg,P ＜ 0.05 ].Two patients in none-indwelling gastric canal group occurred respiratory tract obstruction.There was no significant difference in deglutition function recovery and alimentary tract hemorrhage (P ＞ 0.05).ConclusionPulmonary infection,respiratory tract obstruction,gastrointestinal dysfunction and malnutrition are the potential hazards of dysphagia after brain stem infarction,and indwelling gastric canal,strengthening expectoration and promoting functional recovery are effective preventive measures.
