Design and application of a kind of anti-bedsore turning pad / 中华危重病急救医学

Patients who are bedridden are for a long-time prone to develop bedsores, especially in the hip and sacral areas and limbs, which causes eczema, ulcers, infection and other complications, resulting in pain and more medical costs. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a kind of anti-bedsore turning pad, and has obtained the national utility model patent (ZL 2021 2 3004923.9), which is suitable for various long-term bedridden patients. The anti-bedsore turning pad includes the center axis of the turning pad, and ventilation pad 1 and ventilation pad 2 designed on the left and right of turning pad center axis. Under the ventilation pad 1 and the ventilation pad 2, the air pad 1 and the air pad 2 are respectively designed. There is a bedspread connected with ventilation pad 1 and ventilation pad 2 on the inflatable pad 1 and the inflatable pad 2. Through the design of inflatable pad 1 and inflatable pad 2, the left and right of the anti-bedsore turning pad can be lowered or raised independently, which is convenient for the patient's body to tilt and turn over, and can significantly reduce the number of nursing staff and the burden of nursing staff when turning over. In addition, it is convenient to replace the force site at any time and reduce the occurrence of pressure ulcers caused by long-term pressure on the force site. Through the design of ventilation cushion 1 and ventilation cushion 2, the internal gas flow of the turning pad can be made, and the ventilation between the patient and the turning pad can be kept dry, so as to reduce the occurrence of eczema, ulcers or infection and other complications, and ultimately reduce the occurrence of bedsores. In addition, through the design of the most superficial limb pad, the patient's limb can be appropriately elevated or massaged, which increases the comfort of the patient. The anti-bedsore turning pad is simple and effective, and can be widely used in long-term bedridden patients.

A Randomized Clinical Trial on Therapeutic Effects of Myrtus communis L. Cream on Chronic Skin Lesions and Quality of Life of Sulfur Mustard-exposed Veterans

Abstract: Sulfur mustard is one of the chemical warfare agent. It rapidly reacts with the cutaneous tissues and other tissues, leading to various devastating long-term effects on human health. Mustard-exposed veterans suffer from its chronic skin problems, including itching, burning sensation, and eczema. We aimed to evaluate the protective effects of Myrtus communis L. (myrtle) on chronic skin lesions and quality of life of sulfur mustard-exposed veterans. In this randomized, double-blind clinical trial, 60 sulfur mustard-exposed patients were evaluated. Thirty patients received myrtle essence 5% cream (case group) and 30 patients received Eucerin cream (placebo group) twice in a day for one month. Then, We assessed the chronic skin problems and itching-related parameters (such as the itching time, severity, distribution, frequency, and calculated itching score), duration of sleep, number of waking up at night, and quality of life in the both groups. Our analysis of data revealed that application of myrtle cream effectively decreased skin problems including; itching and burning sensation. Additionally, myrtle markedly decreased skin lesion symptoms such as excoriation in the case group as compared with before treatment. Noticeably, myrtle cream significantly improved quality of life of the patients in the case group. The present study provides more in-depth information regarding the protective role of myrtle on the sulfur mustard-induces skin complication. Also, myrtle effectively improved quality of life of the sulfur mustard-exposed veterans.

Effect of acupuncture and moxibustion on skin barrier function in guinea pigs with eczema of skin damp-heat accumulation / 中国针灸

OBJECTIVE@#To observe the effect of acupuncture and moxibustion on the water content of stratum corneum (WCSC), expression of serum inflammatory factors and aquaporin 3 (AQP3) in skin, lung and rectum in guinea pigs with eczema of skin damp-heat accumulation, and to explore the possible mechanism of acupuncture and moxibustion for regulating skin barrier function.@*METHODS@#A total of 24 male albino guinea pigs were randomly divided into a blank group (n=6) and a modeling group (n=18). The guinea pigs in the modeling group were induced by 2,4-dinitrochlorobenzene (DNCB) to establish the eczema model of skin damp-heat accumulation. The guinea pigs with successful modeling were further randomly divided into a model group, a medication group and an acupuncture-moxibustion group, 6 guinea pigs in each group. The guinea pigs in the medication group were treated with loratadine tablets (0.8 mg/kg) by gavage, once a day for 7 days; the guinea pigs in the acupuncture-moxibustion group were treated with acupuncture at "Feishu" (BL 13), "Pishu" (BL 20), "Quchi" (LI 11), "Zusanli" (ST 36) and "Xuehai" (SP 10); at the same time, moxibustion was applied at "Feishu" (BL 13) and "Zusanli" (ST 36), moxibustion intervention for 10 min and needle retaining for 15 min at each acupoint, once a day for 7 days. The eczema area and severity index (EASI) score was evaluated before and After intervention, and WCSC and trans-epidermal water loss (TEWL) were measured by skin tester. After intervention, The HE staining was used to observe the changes of skin histomorphology in each group; ELISA was used to measure the contents of serum immunoglobulin E (IgE), interleukin (IL)-4 and IL-17; Western blot was used to measure the protein expression of AQP3 in skin, lung and rectum.@*RESULTS@#Before the intervention, compared with the blank group, the EASI scores and TEWL were increased in the remaining groups (P<0.01), and the WCSC was decreased (P<0.01). After the intervention, compared with the model group, the EASI scores and TEWL were decreased (P<0.05, P<0.01), and WCSC was increased (P<0.01) in the medication group and the acupuncture-moxibustion group. The epidermal structure in the blank group was complete and the fibers in the dermis were arranged orderly; in the model group, epidermal hyperkeratosis, proliferation of granular layer, spinous cell layer and basal layer, and disordered arrangement of dermal fibers and infiltration of inflammatory cells were observed. The morphological performance in the medication group and the acupuncture-moxibustion group was better than that in the model group. Compared with the blank group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 and the protein expression of AQP3 in skin, lung and rectum were decreased in the model group (P<0.01, P<0.05). Compared with the model group, the contents of serum IgE and IL-17 were decreased and the contents of serum IL-4 were increased in the medication group and the acupuncture-moxibustion group (P<0.01), and the protein expression of AQP3 in skin, lung and rectum in the acupuncture- moxibustion group were increased (P<0.05). Compared with the medication group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 was decreased (P<0.01) in the acupuncture-moxibustion group.@*CONCLUSION@#Acupuncture and moxibustion could improve the epidermal water metabolism and skin tissue morphology in guinea pigs with eczema of skin damp-heat accumulation. Its mechanism may be related to regulating inflammatory factors, up-regulating the expression of AQP3, and then repairing the skin barrier function.

Evaluación de afección en calidad de vida en adultos con dermatitis atópica / Assessment of quality of life illness in adult patients with atopic dermatitis

Introducción: la dermatitis atópica (DA) es una enfermedad con repercusión en la calidad de vida (CV) del paciente. Para la evaluación de la gravedad clínica de la enfermedad se han diseñado diversas herramientas como el Eczema Area and Severity Index (EASI), mientras que para la evaluación de la CV se han creado instrumentos específico, como el Dermatology Life Quality Index (DLQI) y el Quality of Life Index for Atopic Dermatitis (QoLIAD). Objetivo: definir cuál es la mejor herramienta para evaluar la afección a la CV de pacientes adultos con DA, en relación con el EASI. Material y métodos: se seleccionaron pacientes con DA (> 18 años) que aceptaran responder a los cuestionarios DLQI y QoLIAD, así como tener una exploración dermatológica reportada según el EASI. Se ajustaron tres modelos de regresión lineal simple para poder cuantificar la asociación entre el EASI con el DLQI y el QoLIAD. Un valor de p < 0.05, se consideró de significancia estadística. El modelo de afección a CV con el valor más alto de pseudo R2, se consideró como el que tuvo mayor asociación con EASI. Resultados: se captaron en total 72 pacientes. Los modelos de regresión cuantílica simple revelaron un coeficiente de regresión de 0.243 para DLQI (p = 0.002) y 0.252 para QoLIAD (p = 0.003). Los valores de pseudo R2 fueron de 0.15 para DLQI y 0.10 para QoLIAD, por lo que el DLQI tuvo una mayor correlación con el EASI. Conclusiones: el DLQI resultó ser el mejor instrumento para evaluar la afección a la CV en pacientes adultos con DA.

Background: Atopic dermatitis (AD) is a disease with an im- pact on the patient's quality of life (QoL). Several tools have been designed to assess the clinical severity of the disease, such as the Eczema Area and Severity Index (EASI), while specific instruments have been created to assess QoL, such as the Dermatology Life Quality Index (DLQI) and the Quality of Life Index for Atopic Dermatitis (QoLIAD). Objective: To define which tool is the best to assess the QoL condition of adult patients with AD in relation to the EASI. Material and methods: Patients with AD (> 18 years old) were selected who agreed to complete the DLQI and QoLIAD questionnaires, as well as to have a dermatologic examination reported according to the EASI. Three simple linear regression models were fitted in order to quantify the association between EASI with DLQI and QoLIAD. A value of p < 0.05 was considered statistically significant. The CV condition model with the highest pseudo R2 value was considered to have the strongest association with EASI. Results: A total of 72 patients were included. Simple quantile regression models revealed a regression coefficient of 0.243 for DLQI (p = 0.002) and 0.252 for QoLIAD (p = 0.003). The pseudo R2 values were 0.15 for DLQI and 0.10 for QoLIAD, so DLQI had a higher correlation with EASI. Conclusions: DLQI proved to be the best instrument to assess CV impairment in adult patients with AD.

Síndrome de hiperinmunoglobulinemia E: dermatitis atópica como manifestación inicial. A propósito de un caso / Hyper IgE syndrome: atopic dermatitis as first manifestation. Case report

La dermatitis atópica es la forma más frecuente de eccema durante el primer año de vida; sin embargo, cuando la presentación es atípica o se asocia a infecciones, constituye un desafío diagnóstico para el pediatra. Es importante mantener un índice alto de sospecha para detectar inmunodeficiencias primarias asociadas a eccemas graves desde el período neonatal. Un ejemplo de estas es el síndrome de hiperinmunoglobulinemia E (hiper-IgE) autosómico dominante. Este cuadro se caracteriza por la presencia de infecciones cutáneas y respiratorias recurrentes, dermatitis atópica, eosinofilia y aumento de IgE. Se reporta el caso clínico de una niña de 1 mes y 29 días con diagnóstico de hiper-IgE con afección cutánea desde el nacimiento.

Atopic dermatitis is the most common form of eczema often developed before the first year of life. Nevertheless, when the presentation is atypical or related to infections the diagnostic represents a challenge for the pediatricians. It is important to maintain a high index of suspicion for the detection of primary immunodeficiency associated to severe eczema. One of them is the autosomal dominant hyper-IgE syndrome characterized by recurrent skin and respiratory infections, atopic dermatitis, eosinophilia, and high serum IgE concentrations. In this paper, we report a 1 months and 29 days old baby girl diagnosed with hyper-IgE and a skin involvement since birth.

Alergia à Metilisotiazolinona: Relato de caso / Methylisothiazolinone Allergy: Case Report

A metilisotiazolinona (MI) é um conservante presente em produtos químicos de limpeza e cosméticos na forma isolada ou associada à metilclorotiazolinona (MCI/MI). Seu uso tem sido associado ao aumento progressivo de casos de dermatite alérgica de contato (DAC) no mundo, constituindo uma das principais causas dessa entidade. O diagnóstico padrão-ouro de DAC a essa substância é realizado pelo teste de contato. No Brasil, a bateria padrão contempla apenas o composto MCI/MI, não avaliando isoladamente a MI. Relatamos caso clínico de uma paciente com eczema crônico predominante em mãos, que possuía nexo ocupacional com utilização de produtos de limpeza, tendo apresentado teste de contato, através da bateria Latino-Americana, fortemente positivo (+++) à MI 0,2% e negativo para MCI/MI. Objetivamos demonstrar a importância da inclusão da metilisotiazolinona, de forma isolada, na bateria padrão brasileira para maior sensibilidade diagnóstica, além da necessidade de especificação da presença desse conservante em produtos de limpeza.

Methylisothiazolinone (MI) is a preservative present in cleaning and cosmetic products, in the isolated form or associated to methylchloroisothiazolinone (MCI/MI). Its use has been associated with the progressive increase in cases of allergic contact dermatitis (ACD) in the world, constituting one of the main causes of this entity. The gold standard diagnosis of ACD for this substance is performed by the patch test. In Brazil, the baseline series only includes the MCI / MI compound, not evaluating the MI alone. We case report of a patient with predominant chronic eczema on the hands, who had an occupational nexus with the use of cleaning products, having presented a patch test, through the Latin American series, extremely positive for 0.2% MI (+++) and negative for the MCI/MI. We aim to demonstrate the importance of including methylisothialzoninone, in isolation, in the Brazilian baseline series for greater diagnostic sensitivity, in addition to the need to specify the presence of this preservative in products.

Analysis of animal model of atopic dermatitis based on characteristics of clinical symptoms traditional Chinese and Western medicine / 中国中药杂志

Based on the clinical characteristics of atopic dermatitis( AD) in traditional Chinese medicine( TCM) and Western medicine,the existing animal models were analyzed,and the coincidence degree,advantages and disadvantages between the models and the clinical manifestations of AD were evaluated,so as to provide reference for establishing a rational animal model. After consulting relevant literatures in recent years and summarizing the existing modeling methods,it is found that spontaneous,transgenic/gene knockout models were highly consistent,but with high breeding conditions and expensive prices. The hapten-induced model was low in cost and fast in modeling. It revealed the corresponding mechanism of AD to a certain extent,but did not fully reflect the state of the entire process of AD. The modeling method was guided by Western medicine,but with a lack of pathogenic factors of traditional Chinese medicine,and so has certain limitations in TCM research. Therefore,it is necessary to combine the etiology,pathogenesis and clinical mani-festations of AD with traditional Chinese and Western medicine,so as to improve the coincidence degree between the model and the characteristics of clinical symptoms and lay the foundation for in-depth studies on AD.

Mechanism of Mahuang Lianqiao Chixiaodou Decoction in treating eczema by network pharmacology and molecular docking technology / 中国中药杂志

To study the molecular mechanism of Mahuang Lianqiao Chixiaodou Decoction in the treatment of eczema by means of network pharmacology and molecular docking. First, the TCMSP database was used to excavate the active ingredient of each drug in Mahuang Lianqiao Chixiaodou Decoction and predict its target, and the Uniprot database was used to standardize the names of target proteins, in order to obtain the disease targets of eczema through GeneCards, OMIM, PharmGkb, DrugBank and other databases. And next, the potential targets on which drug targets and disease targets work together were selected to make a Venn diagram, the Cytoscape 3.6.1 software was used to screen out and construct the "active ingredient-core targets" network. STRING database was used to construct a protein-protein interaction(PPI) network, and the R language was used to perform GO enrichment analysis and KEGG pathway analysis. Finally, the molecular docking verification of main active ingredients and core targets of the drug was performed by AutoDock software. The study showed that 74 active ingredients and 103 targets of Mahuang Lianqiao Chixiaodou Decoction for the treatment of eczema were screened. The main active ingredients included quercetin, luteolin, wogonin, kaempferol, and the main targets included PTGS1, ESR1, PPARG, and MAPK3. In addition, eight key targets, including MAPK8, MAPK3, JUN, MAPK14, TP53, MAPK1, ESR1 and RELA, were calculated by PPI network. GO enrichment analysis involved 2 024 biological processes, 81 cell components, and 140 molecular functions. KEGG pathway enrichment analysis was performed to screen out 158 eczema-related pathways, which mainly acted on AGE-RAGE signaling pathway, IL-17 signaling pathway, virus-related pathways, and the results of molecular docking showed that the main active compounds could respectively bind to representative targets and exhibit a good affinity. The study proved that the treatment of eczema with Mahuang Lianqiao Chixiaodou Decoction involved multiple signaling pathways and biological processes, and the combination of main active ingredients(such as quercetin, luteolin, wogonin, kaempferol) and key targets(such as MAPK8, MAPK3, JUN, MAPK14, TP53, MAPK1, ESR1, RELA) may be one of the important mechanisms of action.

Azathioprine: its uses in dermatology

Abstract This is a narrative review of azathioprine. This medication is immunomodulatory and immunosuppressive, and it has been used widely through different medical specialties to modify disease. It has been proven useful for several dermatoses and it has encountered success when used as an off-label indication for other dermatologic diseases. Its mechanism of action is described thoroughly, as well as precautions for monitoring adequate levels in patients using it. Dermatologists should also be aware of the possible adverse events it may present. In dermatology it can be used in bullous and autoimmune diseases, and in other conditions, including intractable pruritus, atopic dermatitis, photodermatoses, psoriasis, and others. Azathioprine offers an alternative as a steroid-sparing agent and this review helps dermatologists prescribe it safely to all patients who require it.

Hiperplasia gengival durante uso de ciclosporina / Gingival hyperplasia during cyclosporine use

Paciente do sexo masculino, com 24 anos, portador de dermatite atópica desde o primeiro ano de vida. Começou a evoluir com forma grave da dermatite atópica aos 17 anos, e devido à refratariedade clínica ao tratamento convencional tópico, foi encaminhado para serviço de referência. Após otimizar os cuidados com uso de emolientes, corticoides tópicos e cursos de antibioticoterapia, manteve persistência de eczema generalizado, com SCORAD oscilando entre 40 e 50 no período de 4 meses. Dessa forma, optou-se por terapia sistêmica, sendo iniciado o uso de ciclosporina oral na dose de 200 mg. A resposta terapêutica com a ciclosporina foi percebida após 4 semanas, sendo refletida na redução do escore de gravidade (SCORAD=10). Durante o seguimento, além da melhora clínica, eram monitorados potenciais eventos adversos. O paciente fez uso da ciclosporina durante 5 anos sem apresentar eventos adversos, com necessidade de aumento de dose para 300 mg/dia dois anos após início da medicação. Porém, neste quinto ano de uso da ciclosporina, o paciente apresentou hipertrofia gengival importante. Assim, optou-se por reduzir a dose de ciclosporina de 300 para 200 mg/dia. Nenhum outro sinal ou sintoma foi observado, e os exames laboratoriais também não mostraram qualquer toxicidade. O paciente se mostrou resistente à redução da medicação, pois o temor de piora das lesões de pele o aflige muito. Orientamos sobre a necessidade de melhorar a higiene bucal de forma disciplinada, e agendamos reavaliação clínica mensal. Além disso, foi encaminhado para avaliação odontológica.

A 24-year-old man had atopic dermatitis since the first year of life. He first developed a severe form of atopic dermatitis at the age of 17, and because of clinical refractoriness to conventional topical treatment, he was referred to an excellence center. After care was optimized with emollients, topical corticosteroids and courses of antibiotic therapy, generalized eczema persisted, with Scoring Atopic Dermatitis (SCORAD) score oscillating between 40 and 50 in a period of 4 months. Thus, systemic therapy was chosen, with use of oral cyclosporine at a dose of 200 mg. Therapeutic response with cyclosporine was observed after 4 weeks, with a reduction in the severity score (SCORAD = 10). During followup, in addition to clinical improvement, potential adverse events were monitored. The patient used cyclosporine for 5 years with no adverse events, requiring a dose increase to 300 mg 2 years after initiating the medication. However, in the 5th year of cyclosporine use, the patient had significant gingival hyperplasia. Thus, we decided to reduce the dose of cyclosporine from 300 to 200 mg. No other signs or symptoms were observed and laboratory tests also showed no toxicity. The patient was resistant to reducing the medication, as he feared the skin lesions would aggravate. We advised him on the need to improve oral hygiene in a disciplined manner and scheduled a monthly clinical reevaluation. In addition, he was referred to dental evaluation.

Uso de probióticos e/ou prebióticos na prevenção de eczema em crianças com alto risco de atopia: uma revisão sistemática / Probiotics and/or prebiotics use on the prevention of eczema in children with high risk of atopy: a systematic review

O objetivo deste estudo foi encontrar a relação do uso de probióticos e/ou prebióticos na prevenção do desenvolvimento de eczema atópico em crianças com alto risco. Foram utilizadas para esta revisão as bases de dados MEDLINE, via PubMed, SciELO e LILACS, com os seguintes descritores "(probiotics OR prebiotics) AND (allergy) AND (eczema)". Foram selecionados ensaios clínicos randomizados publicados até janeiro de 2020, sem restrição de idioma, em humanos, desde o nascimento até os 18 anos de idade. Foram recuperados 247 artigos, sendo cinco utilizados para análise. Quatro estudos não demonstraram relação entre o uso de probióticos e/ou prebióticos e a prevenção de eczema atópico em crianças de alto risco. Em contrapartida, um dos trabalhos obteve associação positiva, porém restrito a crianças com alergia à proteína do leite de vaca. Foi concluído nesta revisão que não existe relação entre o uso de probiótico e/ ou prebióticos em crianças de alto risco de atopia na prevenção de eczema, com possível exceção em crianças com alergia ao leite da vaca, com o desenvolvimento de eczema. É necessário a realização de mais estudos em longo prazo para a confirmação de real associação.

The aim of this study was to assess the relationship between the use of probiotics and/or prebiotics and the onset of eczema in children with high risk of atopy. PubMed, SciELO, and LILACS databases were used with the following descriptors: "(probiotics OR prebiotics) AND (allergy) AND (eczema)." Randomized clinical trials published up to January 2020, with no language restriction, involving humans from birth to 18 years of age were included. In total, 247 articles were found, and five were included in the analysis. Four trials did not show a relationship between the use of probiotics and/or prebiotics and the prevention of atopic eczema in high-risk children. In contrast, one clinical trial reported a positive association, but restricted to children with cow's milk allergy. In conclusion, there is no relationship between the use of probiotics and/or prebiotics and the onset of eczema in children with high risk of atopy, with a possible exception for children with cow's milk allergy. Additional long-term studies are necessary to confirm whether this association is true.

A 5-year retrospective review of children with peanut allergy in the largest paediatric hospital in Singapore

BACKGROUND: The prevalence of peanut allergy (PA) among children has increased significantly over the past decade. Even though the prevalence of PA in Singapore is considered low, peanut is the top trigger for food-induced anaphylaxis in Singaporean children.OBJECTIVE: To describe the demographic characteristics and clinical features of children with PA.METHODS: This is a 5-year retrospective review of children diagnosed with PA based on clinical history coupled with a positive skin prick test to peanut or positive oral food challenge results.RESULTS: There were 269 patients (53.9% males) with a clinical diagnosis of PA. The median age at first allergic presentation for the PA group was 24 months old, with interquartile range of 13–39 months. The most common form of peanut introduced was roasted peanut. The rate of peanut anaphylaxis was 7.1%. Concomitant tree nut sensitization was found in 32.3% of this cohort, predominantly to cashew nut. Majority of them have a personal history of atopy – 75.8% with eczema, 63.6% with allergic rhinitis, and 19.7% with asthma.CONCLUSION: This is the first large review of peanut-allergic children in Singapore. Prospective population-based studies are needed to establish the true prevalence and risk factors associated with the development of this potentially life-threatening condition.

Correlation of nipple eczema in pregnancy with atopic dermatitis in Northern India: a study of 100 cases

Abstract Background Nipple eczema is a less common presentation of atopic dermatitis. No studies in the literature have correlated nipple eczema in pregnancy as a manifestation of atopic dermatitis. Objective To evaluate whether nipple eczema presenting in pregnancy is a manifestation of atopic dermatitis. Methods This was a prospective observational study including 100 women who presented with nipple eczema for the first time during pregnancy. The exclusion criteria were any patient with previous history of nipple eczema, those already on oral or topical treatment for atopic dermatitis or nipple eczema, and other disorders mimicking eczema. Patients were divided into two groups ‒ nipple eczema with atopic dermatitis and without atopic dermatitis. Demographic data, clinical features, total leukocyte count, differential leukocyte count, absolute eosinophil counts, and serum IgE levels were compared between the two groups to detect association between nipple eczema in pregnancy and atopic dermatitis. Results Out of 100 patients, 39 were diagnosed with atopic dermatitis, whereas 61 were ruled out to have any features suggestive of atopic dermatitis. There were no statistically significant differences in mean age, mean duration of symptoms, and serum IgE levels. In patients with atopic dermatitis, bilateral symptoms were noted more commonly than in patients without the disease, but this was statistically insignificant. Study limitations Lack of long term follow-up and no large studies in literature to compare results. Conclusion Nipple eczema in pregnancy follows a similar pattern as in other age groups. The clinical profile of patients is similar in cases with and without atopic dermatitis.

O teste de contato (patch test) na avaliação de sensibilização por alimentos em pacientes com dermatite atópica ­ estudo piloto / Patch testing in the evaluation of food sensitization in patients with atopic dermatitis ­ a pilot study

Objetivos: Investigar o papel do patch test na avaliação da sensibilização por alimentos e no diagnóstico de alergia alimentar em pacientes com dermatite atópica (DA) e comparar duas distintas apresentações do teste. Métodos: Esse estudo prospectivo envolveu 20 crianças (mediana de idade de 8,4 anos) com dermatite atópica moderada ou grave que foram submetidas ao teste cutâneo de hipersensibilidade tardia (patch test ) com alimentos frescos e extratos comerciais, seguidos de teste de provocação oral (TPO) nos casos de resultado positivo, no intuito de avaliar a correlação clínica. Resultados: Entre os 20 pacientes avaliados, somente 4 (20%) apresentaram resultados positivos para o patch test, com maior positividade para os extratos comerciais (3/4), em comparação aos alimentos in natura. Não se observou concordância dos resultados obtidos entre as duas apresentações comparadas. Do total de 7 TPO realizados, 4 foram positivos (soja e milho para um paciente e amendoim para outros dois), com piora das lesões da DA (valor preditivo positivo de 57%). Apenas uma criança apresentou efeito adverso mais significativo. Conclusões: Embora tenha sido encontrada baixa sensibilização aos alérgenos alimentares na população estudada e discordância entre os resultados dos patch tests com alimentos frescos e extratos comerciais, o teste mostrou-se seguro. Para uma melhor análise estatística, recomenda-se estudo em população maior.

Objective: To evaluate the use of patch testing in determining food sensitization and allergy in patients with atopic dermatitis (AD) and compare two distinct assays. Method: Twenty children (median age, 8.4 years) with moderate-to-severe AD were prospectively evaluated by atopy patch test with commercial extracts and fresh food allergens. Positive results were further investigated by oral food challenge (OFC). Results: Only 4/20 patients (20%) had positive patch results, mostly to commercial extracts (3/4) compared to fresh food. There was no agreement between the results of the two presentations tested. Four of seven OFCs were positive (one patient to soy and corn, two others to peanut), with worsening AD eczema (positive predictive value of 57%). One child had a more significant side effect. Conclusion: In spite of poor sensitization rates in the study population and no observed correlation between the two presentations tested, atopy patch testing was safe. Studies with a broader population are needed for better conclusions.
