Curative Effect of 30% Supramolecular Salicylic Acid Combined with Yufa Spray Dressing on Moderate to Severe Scalp Seborrheic Dermatitis

Objective:To observe the clinical efficacy of 30%supramolecular salicylic acid combined with Yufa spray dressing in the treatment of moderate to severe seborrheic dermatitis(seborrheic dermatitis of the scalp,SDS).Methods:From January 2020 to December 2021,150 patients with SDS,who were treated in the Dermatology Clinic of the First Affiliated Hospital of Xi’an Medical University,were randomly divided into two groups,a treatment group and a control group,with 75 cases in each group.The treatment group was given 30%supramolecular salicylic acid combined with Yufa spray dressing on the basis of external medicine given to the control group,while the control group was given oral medicine combined with external medicine.Results:The difference in scores of erythema,scales,pruritus,and folliculitis of the treatment group before and after treatment was significant(P<0.01),indicating that supramolecular salicylic acid combined with Yufa spray dressing can relieve the symptoms of SDS.The difference in scores of erythema of the control group before and after treatment was significant as well(P<0.05),indicating that traditional antibiotics are also effective in treating SDS;however,there was no significant difference(P>0.05)in the scores of other signs and symptoms,such as scales,pruritus,and folliculitis,before and after treatment,indicating that traditional antibiotics have no obvious curative effect on SDS.After 12 weeks of treatment,the improvement in erythema,scaling,and folliculitis was significantly greater in the treatment group compared with the control group(P<0.05).Curative effect comparison showed that the total effective rate of the treatment group was 80.00%,compared with 25.67%of the control group,and the difference was statistically significant(P<0.05).Conclusion:30%supramolecular salicylic acid combined with Yufa spray dressing can significantly improve the therapeutic effect in moderate to severe SDS;the recurrence rate is lower,the course of treatment is shorted,and patients generally feel better;thus,it is a new option for the treatment of dermatitis.

Identification of core compositions of traditional Chinese medicine for Seborrheic Dermatitis using data mining techniques

Objective:To explore the clinical medication rule of seborrheic dermatitis in modern Chinese medicine by data mining,in order to benefit the clinical treatment of seborrheic dermatitis in traditional Chinese medicine.Methods:From January 1,2010 to September 4,2019,articles on Chinese medicine for seborrheic dermatitis were searched systematically in CNKI,VIP and Wan Fang databases.Prescription databases were established through the Chinese Medicine Inheritance assistant system to mine and analyze the rules of data.Results:69 researches were screened out,72 prescriptions for seborrheic dermatitis.13 drugs were used more than or equal to 15 times,and 9 pairs of commonly used drugs with correlation coefficient above 0.045 were selected.Six core combinations and two new prescriptions were obtained.Conclusion:Data mining method was used to analyze the high-frequency drugs and drug pairs,which reflected the treatment principle of clearing heat and removing dampness,nourishing blood and moistening dryness,promoting qi and strengthening spleen in the clinical treatment of seborrheic dermatitis,and provided more intuitive research evidence for the follow-up clinical treatment.

High Staphylococcus epidermidis Colonization and Impaired Permeability Barrier in Facial Seborrheic Dermatitis

Background：Seborrheic dermatitis （SD） is a common inflammatory skin condition.The etiology is unclear,although overgrowth of Malassezia on the skin has been suggested to cause SD.This study investigated whether colonization with Staphylococcus plays a role in facial SD,which was not well addressed previously.Methods：The study was conducted from September 1,2011 to February 20,2012 in the First Hospital of China Medical University.In the first phase,the study evaluated the level of transepidennal water loss （TEWL） and the number of colony-forming units （CFU） of Staphylococcus in defined skin areas of SD patients who were human immunodeficiency virus （HIV） seropositive （HIV [＋] SD [＋] group,n =13）,classical SD （HIV [-] SD [＋] group,n =24） patients,H IV seropositive-non-SD （HIV [＋] SD [-] group,n =16） patients,and healthy volunteers （HIV [-] SD [-] group,n 16）.In the second phase,we enrolled another cohort of HIV （-） SD （＋） patients who applied topical fusidic acid （n =15）,tacrolimus （n =16）,or moisturizer （n =12）.Changes in the Seborrheic Dermatitis Area Severity Index （SDASI）,TEWL,and Staphylococcus density were evaluated 2 weeks later.Comparisons of each index were performed using analysis of variance （ANOVA） and least significant difference method.Results：The level of TEWL was greater through lesional sites in the HIV （＋） SD （＋） group than that in HIV （＋） SD （-） and HIV （） SD （-） groups （95% confidence interval [CI]：18.873-47.071,P 〈 0.001 and 95% CI：28.755-55.936,P 〈 0.001,respectively）.The number of CFU of Staphylococcus was greater in the HIV （＋） SD （＋） group than that in HIV （＋） SD （-） and HIV （-） SD （-） groups （95% CI：37.487-142.744,P =0.001 and 95% CI：54.936-156.400,P 〈 0.001,respectively）.TEWL was significantly more improved in patients treated with tacrolimus and fusidic acid than that in those treated with moisturizers （95% CI：7.560 38.987,P =0.004 and 95% CI：4.659-37.619,P =0.01 1,respectively）.Topical tacrolimus and fusidic acid were significantly associated with decreased SDASI as compared with moisturizer （95% CI：0.03-0.432,P =0.025 and 95% CI：0.033 0.44,P =0.024,respectively）.Conclusions：High colonization with Staphylococcus epidermidis,along with impaired skin permeability barrier function,contributes to the occurrence of SD.

Case report of seborrheic dermatitis

One case of seborrheic dermatitis,male patient,aged 73 years is reported.After treated with acupuncture,penetrating moxibustion and bloodletting therapies,skin lesions on the neck and shoulder regions disappeared,the epidermis returned to normal and itching disappeared.There was no recurrence in the follow-up visit 3 months later.Hence,acupuncture,combined with penetrating moxibustion and bloodletting has a definite effect on this case in the patient and it is worthy of promotion and application in clinical practice.

Prevalence of Cutaneous Disorders in Patients with Polycystic Ovary Syndrome

Purpose: To determine the prevalence of cutaneous disorders of PCOS and indicate the specific cutaneous lesions that have reliable association with PCOS. Methods: 134 female participants had met the criteria to be diagnosed as PCOS. Dermatological examination regarding hirsutism, acne, androgenic alopecia and acanthosis nigricans as well as any other cutaneous manifestations and assessment of each as regards duration, distribution and scoring was done. Hormonal assay for FSH/LH was done together with ultrasound examination. Results: The study included 134 female participants who had met the criteria to be diagnosed as PCOS; the range of age was 18 - 35 years, with a mean (26.31 ± 4.47 years). Among the PCOS patients at least one cutaneous disorder was found in 18 patients (13.4%), two cutaneous disorders in 44 patients (32.8%), three cutaneous disorders in 47 patients (35.1%), four cutaneous disorders in 24 (17.9%) and five cutaneous disorders were found in only one patient (0.7%). Statistically, there was a significant positive correlations between hirsutism, acne, acanthosis nigricans and LH/F.S.H ratio (p < 0.001), and total testosterone level (p = 0.019, p < 0.001, p < 0.001) respectively. Statistically, there was non-significant difference between patients with and without seborrheic dermatitis regarding LH/F.S.H ratio and total testosterone level (p > 0.5). Conclusions: The current study showed the possible association of hirsutism, acne, acanthosis nigricans, and seborrheic dermatitis with PCOS. These cutaneous manifestations could be relied upon as potential cutaneous indicator of PCOS. Using Rotterdam criteria women who met criteria of PCOS had a higher prevalence of hirsutism, acne, AN, androgenic alopecia and seborrheic dermatitis.
