Chinese herbal medicine for seborrheic dermatitis complicated by allergy to topical agent: A case report

Seborrheic dermatitis is a common inflammatory dermatosis.Conventional medical treatments include corticosteroids,calcineurin inhibitors,and other therapeutic modalities.However,the use of the conventional medicine sometimes is limited by adverse effects,such as allergic reaction.We report the case of a 13-year-old girl with seborrheic dermatitis,who was allergic to topical agents and was cured successfully with Chinese herbal medicine.Her Chinese medical syndrome pattern was diagnosed as wind-heat invading the skin and herbs with wind-dispelling and heat-clearing properties were prescribed.Chinese herbal medicine is an alternative modality that can be considered for seborrheic dermatitis,in particular for cases complicated by adverse reactions from conventional topical agents.

Xylooligosaccharides Alleviate Inflammatory Dermatoses and Related Depression-Like Behaviors in Atopic Dermatitis Mice Induced by 2,4-Dinitrofluorobenzene

Objective:To investigate the influence of xylooligosaccharides on skin inflammation,behavioral characteristics,neurotransmitters,and gut flora in a mouse model of atopic dermatitis(AD)induced by 2,4-dinitrofluorobenzene(DNFB).Methods:The AD mouse model was created by administration of DNFB for 14 consecutive days.The scoring atopic dermatitis index,enzyme-linked immunosorbent assay(ELISA),histopathology,and immunohistochemical analyses were used to assess inflammation and depression-like behaviors.Furthermore,high-throughput 16S rRNA gene sequencing was used to determine the composition of fecal microbiota.Results:Xylooligosaccharides treatment reduced the number of scratches and skin thickness,mast cell infiltration and the levels of immunoglobulin(Ig)E and T-helper cytokines compared with the AD model group.Meanwhile,xylooligosaccharides treatment reduced the immobility time of mice in the forced swimming test and increased the total movement distance and movement distance in the center area in the open-field test.Furthermore,5-hydroxytryptamine and dopamine expression in the brain was increased following xylooligosaccharides treatment.Using network pharmacology,Gene Ontology analysis showed that the targets were mainly enriched in phosphatase binding and the regulation of leukocyte differentiation,which ameliorated AD mainly through the hypoxia inducible factor-1 and phosphatidylinositide 3-kinase-protein kinase B pathways.16S rRNA gene sequencing,diversity indices,and gut microbial taxonomic composition analysis showed DNFB-induced changes in intestinal microbiota diversity in AD mice.Comparative analysis indicated that xylooligosaccharides intake improved the gut microbiome by dramatically enhancing the concentration of Lactobacillus while decreasing the concentration of Bacteroides in mice.Conclusion:Xylooligosaccharides reduce inflammatory dermatosis and related depression-like behaviors via regulating intestinal homeostasis,having medicinal value as a nutritional and functional ingredient.

Outcome of Nurses with Occupational Dermatitis

Background: Occupational dermatitis is considered as the second most common occupational disease. It accounts for 25% of all lost workdays. Several international studies reported a prevalence of occupational dermatitis in healthcare workers between 17% and 55%. This study aims to identify factors that affect the professional outcome of nurses suffering from occupational dermatitis. Methods: This was a multicenter cross-sectional study concerning nurses declared having occupational dermatitis in the central region of Tunisia. A synoptic sheet related to socio-professional and administrative data was completed. A self-administered Questionnaire going over medical and occupational characteristics was completed during a direct interview. Results: The study involved forty nurses working in four public hospitals in the center of Tunisia. Only 37 workers were included in the study. A professional reclassification was introduced among 19 workers (51% of study population). Work-station adaptation was requested in 14 cases (38%). Exposure to allergens in the workplace was eliminated in 20 cases. Two study participants were transferred to other departments (5.4%) and three people retired (8.1%). A statistically significant association was found between professional reclassification and a history of allergic manifestations (p = 0.003). Similarly, a significant association was found between professional reclassification and the allergic agent (p = 0.014). Workstation layout was significantly associated with a history of allergic manifestations (p = 0.039), the palm hand location (p = 0.04), professional eviction (p Conclusion: This study identified the main factors influencing the occupational outcome of nurses suffering from occupational dermatitis. This outcome depended on a history of atopy (especially allergic rhinitis) and sensitization to allergens (thiuram mix).

Preparation of anti-canine interleukin-31 receptor alpha polyclonal antibody and evaluation of its therapeutic efect in canine atopic dermatitis

Canine atopic dermatitis(CAD)is a prevalent genetically susceptible infammatory and pruritic allergic skin condition afecting not only the health of dogs but also the quality of life of their owners.Interleukin-31(IL-31)and interleukin-31 receptor alpha(IL-31RA)are essential for the development of pruritus in primates and mice.Hence,it is expected that inhibiting IL-31RA will be an efective approach to alleviate pruritus.The purpose of the study was to produce anti-canine IL-31RA polyclonal antibodies(anti-IL-31RA pAbs)and evaluate their efcacy in inhibiting house dust mite(HDM)-evoked pruritic responses.Dogs were immunized with antigens formed by IL-31RA recombinant short peptides coupled to BSA to produce anti-IL-31RA pAbs.The CAD model was developed by using HDM allergen stimulation,and the efects of IL-31RA pAbs on the reduction of pruritus in CAD model dogs were examined.The Canine Atopic Dermatitis Extent and Severity Index(CADESI)-4 and pruritus Visual Analog Scale(pVAS)were utilized to evaluate pruritic responses,and skin tissue samples were collected from the inguinal area for pathological assessment of skin infammatory cell infltration.The results showed that anti-IL-31RA pAbs with high titers(1:128,000)and specifcity were efectively produced.In the CAD model group,the severity of skin damage,pruritus score,infammatory cell infltration and level of infammatory factors were considerably elevated.Anti-IL-31RA pAbs relieved pruritic behavior and dermatitis in dogs compared to placebo-treated dogs.In conclusion,anti-IL-31RA pAbs efectively suppressed CAD in vivo and are anticipated to be an efective novel treatment for pruritic skin disorders such as CAD.

Blue Cap Is Effective and Safe for the Treatment of Atopic Dermatitis in Children

Background: Atopic dermatitis (AD) is the most common inflammatory skin disease in children. Treatment of AD is based on skin barrier repair and reduction of inflammation. We analyzed the efficacy and safety of activated piroctone olamine (APO)—Blue Cap—in children with AD. Materials and Methods: An open-label interventional clinical study was carried out at three clinical centers in Serbia. A total of 58 patients with AD, aged between 3 and 18 years were included and treated with Blue Cap Foam (100 ml;CATALYSIS S.L. Madrid)—Activated Piroctone Olamine—applied twice a day in the affected areas with eczema for 30 days and final assessment at 45 days from baseline. Photographic documentation, clinical evaluation, therapy effectiveness and safety questionnaires were assessed at baseline, 15, 30 and 45 days. Results: Our results demonstrated a significant reduction in signs (erythema, scaling, infiltration, excoriations, xerosis) and symptoms (pruritus) at weeks 2 and 4 of the study. At the end of the study, most patients had moderate (28.6%) to great (62.5%) disappearance of manifestations and moderate (25%) to great (71.4%) skin quality improvement. The effect and tolerability of the therapy were evaluated as very good in 66.1 % and 67.9% and good in about 14.3% and 17.9%, assessed by the investigator and patient, respectively. Three patients experienced a burning sensation at the beginning of the study, the side-effects were resolved as the patients continued applying the foam. After two weeks of cessation of the investigated foam, a significant percentage of patients experienced worsening in the final assessment done by the investigator as well as the participant. In the final assessment, a significantly high percentage (57.1%) of patients had a total reduction of manifestation, and a significant number of participants considered the applied product as treatment success, assessed by the investigator (62.5%) as well as the participants (66.4%). Conclusions: Blue Cap is effective and safe in children with AD, although further large-scale randomized controlled trials should confirm our study findings.

Acupoint catgut-embedding therapy ameliorates DNCB-induced atopic dermatitis in BALB/c mice by regulating Th2 type immune response and reducing infiltration of CD4^(+)and CD8^(+)cells

Background:This study aimed to assess how acupoint catgut-embedding therapy influences Th2-type immune response and the infiltration of CD4^(+)and CD8^(+)cells in DNCB-induced atopic dermatitis in BALB/c mice.It also conducted an initial examination of the underlying molecular mechanisms.Methods:Seventy-two mice were randomly divided into four groups:normal control,DNCB-induced atopic dermatitis model(AD),AD with acupoint catgut-embedding treatment(ADA),and AD with sham-acupoint catgut-embedding treatment.After DNCB challenge to induce AD,the ADA group received acupoint catgut-embedding therapy treatment at Zusanli(ST 36)and Quchi(LI 11)acupoints every other week from day 8.Mice in the AD with sham-acupoint catgut-embedding treatment group underwent the same procedure as the ADA group but without catgut implantation.Severity was assessed using SCORAD on treatment days 1,10,and 20.On day 18,nine mice per group were euthanized,and the remaining on day 28.Histopathological changes were observed using hematoxylin-eosin and immunohistochemistry staining.TNF-α,IL-4,IL-6,and IL-13 levels were analyzed by ELISA,and GATA3 and STAT6 protein levels by western blot.Results:After 20 days of acupoint catgut-embedding therapy treatment,mice showed reduced dermatitis scores compared to DNCB-induced AD-like mice.Significant decreases occurred in serum IL-4,IL-6,IL-13,and TNF-αlevels.Skin analysis revealed marked reductions in CD4^(+)and CD8^(+)cell infiltration,as well as GATA3 and STAT6 protein levels.Conclusion:Acupoint catgut-embedding therapy may effectively alleviate atopic dermatitis by suppressing Th2 immune responses via the STAT6-GATA3 pathway and reducing CD4^(+)and CD8^(+)T cell infiltration in skin lesions.

Preprocessing and Efficacy Analysis of Comprehensive Anti-Inflammatory Treatment for Lymphedema in Patients with Irritating Contact Dermatitis

Objective: To explore the pre-treatment and efficacy analysis of comprehensive anti-inflammatory treatment for lymphedema in patients with irritating contact dermatitis. Method: Convenience sampling method was used to observe the skin of 160 patients with upper limb lymphedema admitted to the lymphedema outpatient department of our hospital. They were divided into an observation group (80 cases) and a control group (80 cases), and both groups received a course of comprehensive anti-inflammatory treatment (20 treatments). The control group received routine skin care;On the basis of the control group, the observation group received pre-treatment of the affected limb skin: Laofuzi herbal ointment was applied externally to the prone areas of irritating contact dermatitis (such as the upper arm, inner forearm, and cubital fossa). Result: The incidence of irritating contact dermatitis in the observation group was significantly lower than that in the control group (P 0.05). Patients in the observation group felt significantly better in terms of comfort, skin moisture, and itching relief after being wrapped with low elasticity bandages than those in the control group (P Conclusion: Preventive treatment can effectively reduce the incidence of irritating contact dermatitis, prolong the time of stress treatment, thereby increasing efficacy and improving patient compliance.

Advancements in the application of natural extracts for atopic dermatitis treatment

Atopic dermatitis,a common chronic inflammatory skin disease,has an unclear etiology and may involve multiple factors such as genetic predisposition,immune abnormalities,and impaired skin barrier function.Currently,there is no specific medication available for the complete cure of atopic dermatitis.The current treatment approaches mainly focus on symptom relief and control rather than curative treatment.Some commonly used medications for atopic dermatitis,such as topical corticosteroids and immunosuppressants,may have certain adverse reactions and side effects.This review summarizes the research progress on natural extracts in the treatment of atopic dermatitis,aiming to provide a foundation for the development of safe and side-effectfree medications.

Correlation Analysis Between Children with Atopic Dermatitis and Asthma and Factors Affecting Intestinal Flora

Objective:In order to reveal the potential association between intestinal flora and atopic dermatitis with asthma,the study compares the changes in intestinal flora before and after treatment with antibiotics in children and explores the risk factors for the disease development in children.The differences between asthma-controlled children and healthy children were also analyzed to investigate whether there was a correlation between the level of control and intestinal flora in asthmatic children.Methods:367 children with atopic dermatitis and asthma were selected,and the control group was healthy children who did not have other skin diseases.Fecal samples were collected from healthy children and children with asthma,and the intestinal flora was tested at Beijing Nebula Medical Testing Laboratory Co.At the same time,50 children were selected according to the inclusion and exclusion criteria to take amide antibiotics during hospitalization,and stool samples were collected before and after taking antibiotics.Results:The proportion of Gram-positive cocci increased and the proportion of Gram-positive bacilli decreased after the administration of antibiotics in children with atopic dermatitis and asthma(P<0.05),and no significant difference was shown in the gender and age of the children(P>0.05).The proportion of family history of atopic dermatitis with asthma was higher in the experimental group(P<0.05).Conclusion:The use of antibiotics in children with atopic dermatitis with asthma showed a positive correlation with changes in intestinal flora.The use of antibiotics may lead to changes in intestinal flora and increase the risk of atopic dermatitis with asthma.Antibiotic use in infancy and childhood is also recognized as a risk factor for atopic dermatitis with asthma.Therefore,the use of antibiotics should be minimized in preventing and treating atopic dermatitis with asthma.

Successful treatment of lichen amyloidosis coexisting with atopic dermatitis by dupilumab:Four case reports

BACKGROUND Lichen amyloidosis(LA)is a chronic,severely pruritic skin disease,which is the most common form of primary cutaneous amyloidosis.The treatment of LA has been considered to be difficult.LA may be associated with atopic dermatitis(AD),and in this setting,the treatment options may be more limited.Herein,we report four cases of LA associated with AD successfully treated by dupilumab.CASE SUMMARY In this article,we describe four cases of patients who presented with recurrent skin rash accompanied by severe generalized intractable pruritus,diagnosed with refractory LA coexisting with chronic AD.Previous treatments had not produced any apparent improvement.Thus,we administered dupilumab injection subcutaneously at a dose of 600 mg for the first time and 300 mg every 2 wk thereafter.Their lesions all markedly improved.CONCLUSION Dupilumab may be a new useful treatment for LA coexisting with AD.

Dupilumab for treatment of severe atopic dermatitis accompanied by lichenoid amyloidosis in adults:Two case reports

BACKGROUND Lichenoid amyloidosis(LA)is a subtype of primary cutaneous amyloidosis characterized by persistent multiple groups of hyperkeratotic papules,usually on the lower leg,back,forearm,or thigh.LA may be associated with several skin diseases,including atopic dermatitis(AD).The treatment of LA is considered to be difficult.However,as there is some overlap in the etiopathogenesis of LA and AD,AD treatment may also be effective for LA.CASE SUMMARY Case 1:A 70-year-old man was diagnosed with severe AD with LA based on large dark erythema and papules on the trunk and buttocks and dense hemispherical millet-shaped papules with pruritus on the extensor side of the lower limbs.He had a long history of the disease(8 years),with repeated and polymorphic skin lesions.Given the poor efficacy of traditional treatments,this patient was recommended to receive dupilumab treatment.At the initial stage,300 mg was injected subcutaneously every 2 wk.After 28 wk,the drug interval was extended to 1 mo due to the pandemic.Follow-up observations revealed that the patient reached an Eczema Area Severity Index of 90(skin lesions improved by 90%compared with the baseline)by the end of the study.Moreover,Investigator's Global Assessment score was 1,and scoring atopic dermatitis index and numeric rating scale improved by 97.7%and 87.5%compared with the baseline,respectively,with LA skin lesions having largely subsided.Case 2:A 30-year-old woman was diagnosed with severe AD with LA,due to dense and substantial papules on the dorsal hands similar to changes in cutaneous amyloidosis,and erythema and papules scattered on limbs and trunk with pruritus,present for 25 years.After 16 wk of dupilumab treatment,she stopped,and skin lesions completely subsided,without recurrence since the last follow-up.CONCLUSION Dupilumab shows rational efficacy and safety in the treatment of severe AD with LA,in addition to benefits in the quality of life of the patients.

Cryotherapy versus Hydrogen Peroxide in the Treatment of Seborrheic Keratosis

Seborrheic keratosis has a varying degree of pigmentation. In pigmented seborrheic keratosis, the proliferating keratinocytes trigger the activation of neighboring melanocytes by secreting melanocyte-stimulating cytokines. The etiology of seborrheic keratosis is not known. Epidermal growth factors or their receptors have been implicated in the development of seborrheic keratosis. Seborrheic keratoses can safely be left alone, but ugly or easily traumatized ones can be removed with cryotherapy, electrodesiccation, curettage, or shave excision. The present work aims to compare two modalities of treatment for seborrheic keratosis, namely cryotherapy and hydrogen peroxide (30%). Methods: 30 patients with seborrheic keratosis were included in this study. They were divided into two groups, each with 15 patients. The treatment modalities that have been used include cryotherapy and hydrogen peroxide in three different concentrations (30%, 35%, and 40%). Result: The cryotherapy group consisted of 15 patients, 7 males and 8 females. Their ages ranged from 38 to 80 years, with a mean of 56.1 ± 11.4. Clinical and photographic assessments showed complete removal in all 15 patients in this group (100%). As regards the hydrogen peroxide group, this group included 15 patients, distributed among 7 males and 8 females. Their ages ranged from 39 to 90 years, with a mean of 53.9 ± 14.4. Clinical and photographic assessments showed response in only one small superficial lesion in one patient (6.7%) and no response in 14 patients (93.3%). Conclusion: Cryotherapy is an effective, easy, and relatively cheap method for treating seborrheic keratosis.

Ocular manifestations of children with atopic dermatitis in Saudi Arabia

AIM:To examine the incidence of ocular abnormalities in children with atopic dermatitis(AD)in Saudi Arabia and its association with the severity of AD.METHODS:This is a cross-sectional study on 50 children with AD who were between 5 and 16 years of age.The severity of AD was evaluated using the SCORing Atopic Dermatitis(SCORAD)index.All the children underwent slit lamp exams,visual acuity assessment,intraocular pressure measurement,and corneal topography.The children were considered to have an ophthalmic abnormality if one or more of the following signs were present:glaucoma,keratoconus suspicion,in addition to lid,conjunctival,corneal,lenticular,or retinal abnormalities.RESULTS:Based on the SCORAD severity index,14%of children had mild AD(7/50),38%had moderate AD(19/50),and nearly half had severe AD.More than half the children exhibited facial involvement,and half had peri-orbital signs.The mean SCORAD index was 35.75.The mean age was 10.48±3.6y,and the cohort showed a slight male predominance(54%males).Both eyes of the 50 children in the cohort were studied.Based on the ocular examinations,92%of the patients showed ocular abnormalities:lid abnormalities(27/50)followed by keratitis(22/50).Four patients had moderate risk for keratoconus in one eye and eight patients were suspected to have keratoconus.However,SCORAD severity index was not associated with age,sex,or the number or presence of ophthalmic abnormalities.CONCLUSION:This is the first study in Saudi Arabia to evaluate the prevalence of ocular manifestations in children with AD.The results indicate that the majority of children with AD have ocular abnormalities that mainly include lid abnormalities.Based on these findings,larger scale studies are needed to affirm whether regular screening for ophthalmic abnormalities would be beneficial for children with AD in terms of early intervention and prevention of sight-threatening complications.

Investigation of possible relationship between atopic dermatitis and salivary biomarkers,stress,and sleep disorders

Atopic dermatitis(AD)is a chronic,relapsing,multifactorial inflammatory disease with genetic,environmental,and immunological characteristics.The quality of life and sleep of patients and their families are affected by AD,which triggers stress,described as one of the factors that worsens AD.Salivary biomarkers such as cortisol,alpha-amylase,chromogranin A,and melatonin have been associated with stress and sleep disturbances.Therefore,the evaluation of stress and sleep disorders using salivary biomarkers in AD patients is important.This review aims to describe the possible relationship between atopic dermatitis and stress,sleep disorders,and salivary biomarkers,seeking to contribute to better understanding and clinical management of AD.This descriptive study is characterized as a narrative literature review.A literature search was conducted of studies published in English and Portuguese between January 2012 and October 2022 that are available in electronic media from various databases,such as Scientific Electronic Library Online,Latin American and Caribbean Literature on Health Sciences,and PubMed.AD is associated with different degrees of impact on the lives of individuals who present with the disease.Psychological stress may induce changes in saliva composition and worsen AD;at the same time,the severity of the disease may be associated with emotional impact.Further studies are needed to assess and correlate AD severity,stress,and sleep disturbances with salivary biomarkers in order to better understand this association.

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.

Digital Dermatitis in Dairy Cattle Is Still a Serious Problem in Western Europe

Bacterial infections are quite common in dairy cattle,and frequently related to internal organ systems like e.g.respiratory,intestinal and udder infections.Lameness in dairy cattle is mainly caused by both infectious and non-infectious hoof problems and these have different etiological background.At the moment(2018)the major infectious hoof disorders are DD(Digital Dermatitis)and IP(Interdigital Phlegmon).These are all due to infection from the area where dairy cows normally live and more or less intensive contact with“contaminated”manure.This paper gives insight in these different dermatitis problems cows are daily confronted with,with a focus on infectious hoof disorders as a more or less permanent problem in today’s dairy farming.

A Novel Regimen for Perioral Dermatitis by Photodynamic Therapy

Some patients with perioral dermatitis are not relieved despite many medications. These patients confront pain, psychological bother and social/occupational limitations. Being efficient for a wide variety of diseases including infectious inflammative degenerative or tumoral, photodynamic therapy holds a good chance to cure diseases of unknown origin, such as perioral dermatitis. This study presents the results of three women with chronic perioral dermatitis that persisted for years with partial response to medical regimen. They asked for photodynamic treatment to ease off their suffering. The duration of follow-up was up to five years. Following PDT （photodynamic therapy）, the patients discontinued medications, redness decreased and eruption disappeared. In these patients, a single PDT treatment provided prolonged relief of perioral dermatitis for up to three years. These data are encouraging but not sufficient. Further study is warranted.
