ABSTRACT
Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65%,69.16% and 65.49% of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72%,42.40% and 18.25% of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P<0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P<0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value <0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.
ABSTRACT
Objective To evaluate the efficacy of Qingpeng ointment for the treatment of asteatotic eczema and its effect on skin barrier function.Methods A self-controlled clinical study was performed.Totally,78 patients with asteatotic eczema symmetrically located on both lower extremities were enrolled into this study.The left and right lower extremities of these patients were treated with Qingpeng ointment (Qingpeng group) and hydrocortisone butyrate ointment (hydrocortisone butyrate group) respectively,twice a day for 4 consecutive weeks.At the end of treatment,therapeutic effect and skin barrier function were compared between the 2 groups.Results The response rate was significantly higher in the hydrocortisone butyrate group than in the Qingpeng group after 1-and 2-week treatment (week 1:58.97% vs.39.74%,x2 =5.77,P < 0.05;week 2:76.92% vs.60.26%,x2 =5.03,P < 0.05),but insignificantly different between the 2groups after 4-week treatment (80.77% vs.87.18%,P > 0.05).Compared with the hydrocortisone butyrate group,theQingpeng group showed significantly increased water content of the stratum corneum after 4-week treatment (P < 0.05),and decreased transepidermal water loss after 2-and 4-week treatment (both P < 0.05).Conclusion Qingpeng ointment is safe and effective for the treatment of asteatotic eczema with gradually increasing and stable effects,and also has a favoring effect on the restoration of skin barrier function.
ABSTRACT
Objective To investigate the incidence and risk factors of surgical site infection(SSI)in neurosurgical patients in a tertiary first-class hospital,and provide reference for the prevention and control of SSI.Methods 47 neurological patients with SSI (49 patients developed SSI,2 were excluded from study due to the lack of appropriate control subject)from December 31 ,2011 to December 31 ,2012 were as infected group,and 94 patients without SSI (1 ∶2 matching)were as non-infected group,risk factors for SSI were analyzed retrospectively.Results There was no significant difference in general condition of two groups of patients (all P >0.05 );among 3 708 patients,49 (1 .32%)developed SSI;intracranial infection was the main type of SSI (89.80%);27 patients were performed ce-rebrospinal fluid (CSF)bacteriological detection,6 (22.22%)of whom were positive for CSF bacteriological detec-tion.Univariate conditional logistic regression analysis showed that risk factors for SSI in neurosurgical patients were operational risk assessment score (OR =2.04),frequency of preoperative antimicrobial use(OR =3.15 ),fre-quency of intraoperative antimicrobial use(OR=2.58),duration of operation(OR=2.70),surgical blood loss(OR=1 .72),indwelling drainage tube(OR=4.30),duration of indwelling drainage tube after operation(OR=2.06),and time for initial dressing change(OR=1 .66);Multivariate conditional logistic regression analysis showed that the in-dependent risk factors for SSI were frequency of preoperative antimicrobial use(P =0.03,OR =4.86),duration of operation(P =0.05,OR = 2.89 ),and time for initial dressing change after operation (P = 0.01 ,OR = 1 .92 ). Conclusion Risk factors for SSI in department of neurosurgery are multiple,duration of operation,duration of in-dwelling drainage tube after operation,and time for initial dressing change after operation are major risk factors.
