Nova ocorrência de lepidopterismo por Hylesia nigricans (Berg, 1875) (Lepidoptera: Saturniidae) no Rio Grande do Sul, Brasil / New occurrence of lepidopterism by Hylesia nigricans (Berg, 1875) (Lepidoptera: Saturniidae) in Rio Grande do Sul, Brazil

Adult forms of lepidopterans can cause health problems. This type of incident is known as Lepidopterism, which is caused by contact with urticating setae released by adults, such as those from the Hylesia Hübner (Saturniidae) genus. In this study, the objective is to document a new occurrence of lepidopterism caused by specimens of Hylesia nigricans(Berg, 1875) (Lepidoptera: Saturniidae). The outbreak took place in the summer of 2017 in the municipality of Três Coroas, Rio Grande do Sul, Brazil. During this period, approximately 300 people were affected by dermatitis in the municipality.The outbreak resulted from the release of two types of urticating setae by female moths in the area. We want to emphasize that in case of proliferation of this moth species, it is essential to instruct the population to avoid direct contact with these insects. Monitoring these groups of lepidopterans is fundamental in facilitating decision-making and ensuring public health. (AU)

Formas adultas de lepidópteros podem causar problemas de saúde. Esse tipo de acidente é conhecido como lepidopterismo, causado pelo contato com cerdas urticantes liberadas por adultos, como as do gênero Hylesia Hübner (Saturniidae). Neste estudo, o objetivo é registrar uma nova ocorrência de lepidopterismo causado por espécimes de Hylesia nigricans (Berg, 1875) (Lepidoptera: Saturniidae). O surto ocorreu no verão de 2017, no município de Três Coroas, Rio Grande do Sul, Brasil. No período, aproximadamente 300 pessoas foram acometidas por dermatite no município. O surto foi causado pela liberação de dois tipos de setas urticantes das mariposas fêmeas no ambiente. Ressaltamos que na ocorrência da proliferação dessa espécie de mariposa, é importante instruir a população a evitar o contato direto com esses insetos. O monitoramento desses grupos de lepidópteros é fundamental para facilitar a tomada de decisões e garantir a saúde pública. (AU)

Relationship between atherogenic index of plasma and childhood asthma / 中国当代儿科杂志

OBJECTIVES@#To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma.@*METHODS@#This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis.@*RESULTS@#The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686).@*CONCLUSIONS@#AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

Associations of genetic variations in pyroptosis related genes with acute adverse events in postoperative rectal cancer patients receiving concurrent chemoradiotherapy / 中华肿瘤杂志

Objective: This study aims to investigate the associations between genetic variations of pyroptosis pathway related key genes and adverse events (AEs) of postoperative chemoradiotherapy (CRT) in patients with rectal cancer. Methods: DNA was extracted from the peripheral blood which was collected from 347 patients before CRT. Sequenom MassARRAY was used to detect the genotypes of 43 haplotype-tagging single nucleotide polymorphisms (htSNPs) in eight pyroptosis genes, including absent in melanoma 2 (AIM2), caspase-1 (CASP1), caspase-4(CASP4), caspase-5 (CASP5), caspase-11 (CASP11), gasdermin D (GSDMD), gasdermin E (GSDME) and NLR family pyrin domain containing 3 (NLRP3). The associations between 43 htSNPs and AEs were evaluated by the odd ratios (ORs) and 95% confidence intervals (CIs) by unconditional logistic regression models, adjusted for sex, age, clinical stage, tumor grade, Karnofsky performance status (KPS), surgical procedure, and tumor location. Results: Among the 347 patients with rectal cancer underwent concurrent CRT with capecitabine after surgery, a total of 101(29.1%) occurred grade ≥ 2 leukopenia. rs11226565 (OR=0.41, 95% CI: 0.21-0.79, P=0.008), rs579408(OR=1.54, 95% CI: 1.03-2.29, P=0.034) and rs543923 (OR=0.63, 95% CI: 0.41-0.98, P=0.040) were significantly associated with the occurrence of grade ≥ 2 leukopenia. One hundred and fifty-six (45.0%) had grade ≥ 2 diarrhea, two SNPs were significantly associated with the occurrence of grade ≥ diarrhea, including CASP11 rs10880868 (OR=0.55, 95% CI: 0.33-0.91, P=0.020) and GSDME rs2954558 (OR=1.52, 95% CI: 1.01-2.31, P=0.050). In addition, sixty-six cases (19.0%) developed grade ≥2 dermatitis, three SNPs that significantly associated with the risk of grade ≥2 dermatitis included GSDME rs2237314 (OR=0.36, 95% CI: 0.16-0.83, P=0.017), GSDME rs12540919 (OR=0.52, 95% CI: 0.27-0.99, P=0.045) and NLRP3 rs3806268 (OR=1.51, 95% CI: 1.03-2.22, P=0.037). There was no significant difference in the association between other genetic variations and AEs of rectal cancer patients (all P>0.05). Surgical procedure and tumor location had great impacts on the occurrence of grade ≥2 diarrhea and dermatitis (all P<0.01). Conclusion: The genetic variants of CASP4, CASP11, GSDME and NLRP3 are associated with the occurrence of AEs in patients with rectal cancer who received postoperative CRT, suggesting they may be potential genetic markers in predicting the grade of AEs to achieve individualized treatment of rectal cancer.

Patología dermatológica facial asociada al uso de la mascarilla durante la pandemia causada por el virus Sars-CoV-2 / Facial dermatological pathology associated with use of the mask during the pandemic caused by the Sars-CoV-2 virus

The use of facemask has become a key element to prevent the infection of Covid-19. Its prolonged use, both, by health personnel and the general population, has caused the appearance of multiple adverse effects at the facial level; highlighting the report of symptoms such as discomfort with the mask, facial itching, redness, erythema, among others. The appearance of dermatological diseases such as acne, allergic and irritative contact dermatitis, and exacerbation of pre-existing pathologies such as acne, rosacea and seborrheic dermatitis are also frequent. Knowledge of these complications is important for their prevention and proper management. (AU)

Allergic contact hand dermatitis due to constituents of nitrile gloves

Purpose: This report of a case of allergic contact hand dermatitis due to constituents of nitrile gloves is to bring to the attention of practitioners four important practice points: 1) allergic contact dermatitis may occur due to exposure to chemicals in nitrile gloves; 2) skin patch testing is used to identify the causative allergens; 3) targeted allergens may be necessary in addition to the baseline European standard series if the standard series is unhelpful; and 4) there are potential interventions to manage nitrile glove dermatitis. Findings: A laboratory analyst had occupational exposure to several allergens and had worn latex gloves. She was exposed to laboratory chemicals and powdered ore dust, containing precious metals. She developed hand dermatitis and was relocated to administrative duties not requiring glove use. Her dermatitis cleared but recurred when she returned to the laboratory and started using nitrile gloves. On history, nitrile gloves and platinum group metal ore dust were consistently associated with her hand dermatitis, but laboratory chemicals were not. Latex-specific immunoglobulin E (IgE) was negative, as were skin patch tests for 13 allergens in the metal series, including salts of platinum group metals. She had positive allergic reactions to cobalt chloride, formaldehyde, nickel sulphate, and quaternium 15 in the European standard series patch tests. She did not react to the rubber chemicals in the European standard series, including thiuram mix. The patient was then tested with the rubber additives series because of the glove-relatedness of her hand dermatitis. She had positive reactions to three thiuram compounds used as accelerators in rubber gloves. The patient went on vacation during which time her dermatitis improved. She was relocated to a position without glove use or ore contact and her dermatitis did not recur. Conclusions: An analytic laboratory worker developed hand allergic contact dermatitis due to nitrile glove constituents. The diagnosis is supported by the improvement in her dermatitis after cessation of glove use, negative metal series patch tests, and positive patch tests to accelerators found in rubber gloves. Nevertheless, a contribution to the dermatitis by metals in the platinum group metal ore dust cannot be excluded. Recommendations: Nitrile glove constituents should be considered in wearers who develop hand dermatitis. Skin patch testing is recommended to investigate putative agents. Specific patch test series for more targeted testing may be required

Lesión dermatológica en zona de tatuaje / Dermatological lesion in tattoo area

Los tatuajes representan una situación in vivo única en la que una gran cantidad de sales metálicas y tintes orgánicos permanecen en la piel durante toda la vida. Como resultado de un mayor número de tatuajes realizados, la incidencia de complicaciones cutáneas asociadas a los tatuajes ha aumentado también. En los últimos 30 años se ha evidenciado un aumento de reportes de tumores cutáneos en los tatuajes; sin embargo, muchos autores siguen considerándolo un evento fortuito. Los posibles efectos cancerígenos locales de los tatuajes siguen sin estar claros. Se cree que este efecto podría ser multifactorial y que combina traumatismo de la aguja, inflamación local crónica, factores externos como la exposición a los rayos ultravioleta (UV) y un posible efecto pro-cancerígeno de las tintas. Se necesitan estudios epidemiológicos y clínicos a gran escala para demostrar esta asociación. Se presenta un caso de un hombre de 40 años, conocido sano, quien 2 meses después de tatuarse el hombro derecho, desarrolla una lesión con características clínicas de un queratoacantoma y a quien se le realiza el diagnostico histológico de un carcinoma espinocelular bien diferenciado e invasor.

Tattoos represent a unique in vivo situation where many metallic salts and organic dyes remain on the skin for a lifetime. As a result of a greater number of tattoos performed, the incidence of skin complications associated with tattoos has increased. In addition, in the last 30 years, there has been an increment in reports of skin tumors within tattoos; however, many authors continue to consider it is a coincidental event. The possible local carcinogenic effects of tattoos remain unclear. It is believed that this effect could be multifactorial, combining needle trauma, chronic local inflammation, external factors such as an ultraviolet rays (UV) exposure and a possible pro-cancer effect of the inks. Large-scale epidemiological and clinical studies are needed to demonstrate this association. A case of a known healthy 40-year-old male is presented, in whom 2 months after a tattoo was performed on his right shoulder, he developed a lesion with clinical characteristics of a keratoacanthoma in which the histological diagnosis of a well differentiated and invasive squamous cell carcinoma was made.

Infestação por piolhos Felicola subrostratus em felino domiciliado no município de Parnaíba, Piauí / Infestation by Felicola subrostratus in a feline domiciled in the municipality of Parnaíba, Piauí / Infestación de piojos Felicola subrostratus en felino domiciliado en el municipio de Parnaíba, Piauí

O piolho da espécie Felicola subrostratus é um inseto mastigador responsável por causar a pediculose em felinos e, apesar de ser cosmopolita, tem sua ocorrência pouco descrita na rotina clínica. A transmissão ocorre através do contato direto entre os animais ou por fômites contaminados. Os gatos parasitados podem ser assintomáticos quando em baixa parasitemia, porém em altas infestações podem apresentar prurido, alopecia, dermatites e possibilitar a ocorrência de infecções secundárias. O objetivo deste trabalho foi relatar a infestação por piolhos da espécie Felicola subrostratus em um felino domiciliado no município de Parnaíba, Piauí. O animal era um macho castrado, de dois anos de idade, sem raça definida (SRD), que foi atendido em uma clínica veterinária da cidade, apresentando como queixa principal uma dermatite por lambedura no membro posterior direito, além de prurido, alopecia, apatia, diminuição de apetite e perda de peso. No exame físico, observou-se a dermatite no membro, sendo realizado raspado cutâneo e coleta de pelos da região, verificando a presença de ectoparasitos. Os insetos foram colocados em recipientes com álcool 70ºGL e enviados ao Laboratório de Parasitologia da Universidade Federal do Piauí, que por meio da morfologia revelou ser piolhos da espécie Felicola subrostratus, confirmando o diagnóstico primário de pediculose felina, sendo essencial um diagnóstico precoce para direcionar a um tratamento adequado.(AU)

The lice from the Felicola subrostratus species is a chewing insect responsible for causing pediculosis in felines and, despite being cosmopolitan, its occurrence has been little described in the clinical routine. Transmission occurs through direct contact between animals or through contaminated fomites. The parasitized cats can be asymptomatic when in low parasitemia, but in high infestations, they can present pruritus, alopecia, dermatitis and allow the occurrence of secondary infections. The purpose of this study was to report the infestation by lice of the Felicola subrostratus species in a feline domiciled in the municipality of Parnaíba, in the state of Piauí, Brazil. The animal was a neutered male, two years old, of mixed breed, which was treated at a veterinary clinic in the city, presenting as main complaint a lick dermatitis on the right hind limb, in addition to pruritus, alopecia, apathy, decreased appetite and weight loss. On physical examination, dermatitis was observed on the limb. Skin scraping was performed and fur was collected from the region, verifying the presence of ectoparasites. The insects were placed in recipients with 70ºGL alcohol and sent to the Parasitology Laboratory at the Federal University of Piauí, which through morphology revealed to be lice of the Felicola subrostratus species, confirming the primary diagnosis of feline pediculosis, being essential an early diagnosis to guide the appropriate treatment.(AU)

Exantema intertriginoso y flexural simétrico por fármacos: presentación de un caso / Symmetrical drug-related intertriginous and flexural exanthema: a case report

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a benign, self-limited, immune-mediated, symmetric erythematous rash involving the buttocks and other intertriginous/flexural areas, observed after systemic exposure to a drug in an individual with or without prior sensitization. We present a 70-year old patient, who presented SDRIFE after the administration of piperacillin-tazobactam which improved rapidly after its suspension.

El exantema intertriginoso y flexural simétrico relacionado con fármacos (SDRIFE, por su sigla en inglés) es una erupción eritematosa simétrica, inmunomediada, benigna y autolimitada, que compromete glúteos y otras áreas intertriginosas, flexurales o ambas, y que se observa luego de la exposición sistémica a un fármaco en un individuo con sensibilización previa o sin ella. Se comenta el caso clínico de un paciente de 70 años de edad, que presentó SDRIFE posterior a la administración de piperacilina-tazobactam y que mejoró rápidamente luego de su suspensión.

Uso de terapêutica homeopática em dermatites recorrentes na rotina clínica de animais de companhia: uma revisão / use of homeopathic therapeutics in recurrent dermatitis in the clinical routine of companion animals: a review

Na clínica veterinária as patologias chamadas afecções dermatológicas representam uma porcentagem significativa dos atendimentos, podendo ser de cunho multifatorial ou unifatorial como infecciosa, alérgena ou psicogênica e acometem felinos e caninos de todas as idades. Comumente os medicamentos homeopáticos são usados como último recurso após insucessos consecutivos com a utilização da terapia alopática. Desta forma, esse artigo visa trazer uma revisão bibliográfica de trabalhos científicos que confirmam a eficácia de terapêuticas que utilizam intervenções homeopáticas para o tratamento de dermatites em animais de companhia. Tem-se, portanto, o intuito de propiciar uma maior divulgação das possibilidades de ação/utilização da homeopatia pela comunidade médica veterinária, evitando-se com isso possíveis efeitos adversos devido à utilização de medicações alopáticas.

In the veterinary clinic, the pathologies called dermatological illnesses represent a significant percentage of the consultations, being of a multifactorial or unifactorial nature such as infectious, allergenic or psychogenic and affect felines and canines of all ages. Homeopathic medicines are commonly used as a last resort after consecutive failures with the use of alopathic therapy. Thus this article aims to bring a bibliographic review of scientific papers that confirm the efficacy of therapies that use homeopathic interventions for the treatment of dermatitis in company animals. Therefore it is intended to provide a greater dissemination of the possibilities of action/use of homeopathy by the veterinary medical community thereby avoiding possible adverse effects due to the use of alopathic medications.

Dermatite néonatale: à propos de 116 cas recueillis dans un CHU d'Abidjan / Newborns dermatitis: about 116 cases collected in a university hospital in Abidjan

Objectifs : Déterminer le profil épidémiologique des dermatoses du nouveau-né et de décrire les différents aspects cliniques des dermatoses néonatales observées. Matériel et méthodes : L'étude s'est déroulée au Centre hospitalier universitaire de Cocody (Abidjan). L'étude était transversale, à visée descriptive et analytique, réalisée sur la base d'un recrutement prospectif. Ont été inclus, les nouveau-nés ayant été vus en consultation externe ou en hospitalisationdu 4 avril 2018 au 23 août 2018 chez qui le médecin pédiatre avait observé des lésions cutanées et/ou muqueuses.Ensuite,le diagnostic était posé par le dermatologue référant de l'étude. Résultats : Pendant la période d'étude, 116 nouveau-nés ont été recensés. La moyenne d'âge était 16,86 ± 8,4 jours avec un âge médian de 19 jours. Lesex ratio (H/F) était de 1. Dans plus de la moitié (53,5%) des cas, les lésions évoluaient depuis moins de 5 jours. Une dermatose transitoire était diagnostiquée dans plus de la moitié des cas (51,7%) et dans près du tiers des cas (32,6%) une dermatose infectieuse. Les dermatoses transitoires du nouveau-né étaient dominées par la miliaire sudorale (40%), l'érythème toxique (23%), la desquamation néonatale (10,7%) et l'hyperplasie néonatale (10,7%). Les taches mongoloïdes représentaient3,3% des cas. Les dermatoses infectieuses étaient essentiellement représentées par des infections mycosiques (68,4%) et bactériennes (31,6%). Les autres dermatoses néonatales observées étaient dominées par dermite du siège (64,3%) et les nævi congénitaux (21,5%). Plus de la moitié (57,1%) des cas d'érythème toxique néonatal survenaient entre le 6e et le 10e jour de vie. L'âge moyen des patients présentant une dermatose transitoire était de 14,31 jours contre 19,41 jours pour ceux présentant les autres dermatoses. La différence observée au niveau de l'âge était statistiquement significative (p < 0,05). Conclusion: Les dermatoses néonatales sont multiples et variées. Certaines sont transitoires, ne nécessitant pas toujours de prise en charge thérapeutique. Leur diagnostic n'est pas toujours évident pour le pédiatre d'où la nécessité d'une étroite collaboration entre pédiatres et dermatologues afin d'améliorer la démarche diagnostique et parfois thérapeutique

Aims: To determine the epidemiological profile of newborn dermatitis and to describe the different clinical aspects of the observed neonatal dermatitis. Procedure: The study took place at the University Hospital of Cocody (Abidjan). The study was cross-sectional, descriptive and analytical, carried out on the basis of prospective recruitment. The study included newborns who were seen in outpatient or inpatient settings by 4 april 2018 to 23 August 2018 and in whom the pediatrician had observed cutaneous and/or mucosal lesions. The diagnosis was made with the collaboration of a dermatologist. Results: During the study period, 116 newborns were identified. The age of the patients seen in pediatrics with dermatitis varied from 1 to 28 days, with a mean of 16.86 ± 8.4 days. The median age was 19 days. The most representative age range (32.8%) was 24-28 days. The sex ratio (M/F) was 1. In almost 2/3 of the cases, the children were born at term, 29.3% were premature and 5.2% were born after term. In almost 2/3 of the cases (63.8%), the newborns had a birth weight of more than 2500 g. Only 3.4% of newborns seen in pediatric consultations were referred for a dermatitis. The age of the lesions at the time of consultation varied from 1 to 26 days, with a mean of 06.19 days ± 5.13. In more than half (53.5%) of the cases, the lesions had evolved for less than 5 days. Transient dermatitis was more frequent (51.7%), followed by infectious dermatitis (32.8%). Transient dermatitis of the newborn was dominated by sweaty miliaria (40%). Infectious dermatitis were mainly represented by mycotic (68.4%) and bacterial (31.9%) infections. Bacterial dermatitis were composed of neonatal impetigo (83.3%) and folliculitis (16.7%). In almost half of the cases (46.1%) the mycotic dermatitis were represented by candidosis intertrigo and in 38.5% of the cases there was oral candidiasis. The other neonatal dermatitis observed were dominated by diaper rash (64.3%) (Photo 2) and congenital nevi (21.5%). More than half (57.1%) of the cases of toxic erythema neonatorum occurred between days 6 and 10 of life. Nearly half (41.6%) of the cases of sudoral miliaria occurred between birth and day 5 of life. More than half (57.1%) of the cases of sebaceous hyperplasia occurred before the 5th day of life. All cases of neonatal scaling and mongoloid spots were already present between birth and day 5 of life. The mean age of patients with transient dermatitis was 14.31 days compared with 19.41 days for those with the other dermatitis. The difference in age was statistically significant (p < 0.05). The transient dermatitis predominated in male neonates while the other dermatitis predominated in females, however the difference observed at the level of sex was not statistically significant (p > 0.05). Conclusion: The diagnosis of neonatal dermatitis is not always obvious, especially on black skin where few publications have been published

Comportamiento clínico-epidemiológico del eritema nudoso en el Hospital Provincial Docente Clínico Quirúrgico León Cuervo Rubio / Epidemiological clinical behavior of erythema nodosum at the Provincial Teaching Clinical Surgical Hospital Leon Cuervo Rubio

RESUMEN Introducción: el eritema nudoso es la variante clínico-patológica más frecuente de la paniculitis. Es una reacción cutánea inmunológica en respuesta a un amplio espectro de agentes etiológicos. Objetivo: caracterizar el comportamiento clínico-epidemiológico del eritema nudoso. Materiales y métodos: se realizó un estudio descriptivo, prospectivo y longitudinal en pacientes con diagnóstico de eritema nudoso, ingresados en el Hospital Provincial Docente Clínico Quirúrgico León Cuervo Rubio, de Pinar del Río, en el período de enero de 2017 a diciembre de 2018. El universo estuvo constituido por 34 pacientes con diagnóstico clínico de eritema nudoso, hospitalizados en los servicios de Medicina Interna y Dermatología. Para la recogida de la información se utilizaron la historia clínica, el examen físico y los exámenes de laboratorio. Se utilizaron métodos teóricos, empíricos y estadísticos; de los últimos se empleó la estadística descriptiva a través de frecuencias absolutas y porcentaje. Resultados: el mayor grupo de pacientes estuvo entre 30 y 39 años, y fue del sexo femenino. Las lesiones fueron más frecuentes en los meses de invierno. El tipo de eritema nudoso idiopático prevaleció. Predominó el tiempo de evolución de 1 a 3 meses. Como causa secundaria predominaron las infecciones, y los tratamientos más usado fueron los antiinflamatorios no esteroideos. Conclusiones: se trata de una importante enfermedad de salud, cuyo un diagnóstico etiológico temprano permite un tratamiento adecuado. Resulta difícil su identificación y manejo tanto en la atención primaria como en la secundaria (AU).

ABSTRACT Introduction: erythema nodosum is the most common clinical-pathological variant of panniculitis. It is an immunological skin reaction in response to a wide spectrum of etiologic agents. Objective: to characterize the clinical-epidemiological behavior of erythema nodosum. Materials and methods: a descriptive, prospective and longitudinal study was carried out in patients with diagnosis of erythema nodosum, admitted to the Provincial Teaching Clinical Surgical Hospital León Cuervo Rubio, of Pinar del Río, in the period January 2017 to December 2018. The universe was formed by 34 patients with clinical diagnosis of erythema nodosum, hospitalized in the services of Internal Medicine and Dermatology. Medical records, physical examination and laboratory tests were used for the collection of information. Theoretical, empirical and statistical methods were used; descriptive statistics was used through absolute frequencies and percentage. Results: the largest group of patients was between 30 and 39 years, and they were female. Injuries were more frequent in the winter months. The type of idiopathic erythema nodosum prevailed. The time of evolution prevailed from 1 to 3 months. Infections predominated as a secondary cause, and the most commonly used treatments were non-steroidal anti-inflammatory drugs. Conclusions: it is an important health condition, whose early etiological diagnosis allows the proper treatment. Its identification and management in both primary and secondary care is difficult (AU).

Síndrome de Cushing secundario a administración tópica decorticoesteroides / Cushing Syndrome due to topical corticosteroid misuse

Los corticoesteroides tópicos son drogas muy comunes, frecuentemente utilizadas en patologías dermatológicas. Su mal uso puede causar efectos sistémicos, como el síndrome de Cushing y la supresión del eje hipotalámico ­ hipofisiario ­ adrenal. Presentamos un caso de un lactante menor de siete meses quien desarrolla un síndrome de Cushing secundario al uso de Clobetasol por una dermatitis en el área del pañal, por tiempo prolongado, sin prescripción médica. Al examen físico se evidencia obesidad a predominio central, con fascie de luna llena, hipertricosis en región frontal, telangiectasias aisladas en mejillas y cuello de búfalo. Los paraclínicos demuestran una hipercolesterolemia, hipertrigliceridemia, elevación de las transaminasas y cortisol sérico en la mañana disminuido. Se concluye que se debe informar a los padres de los efectos adversos sistémicos de los esteroides tópicos y se sugiere evitar en pacientes pediátrico(AU)

Topical corticosteroids are very common drugs used in the treatment of inflammatory skin diseases. Prolonged ormisuse of them may cause systemic adverse effects, including Cushing syndrome and hypothalamic-pituitary-adrenal axissuppression. We present a case of a seven months old maleinfant who developed iatrogenic Cushing syndrome after diaperdermatitis treatment through misuse of Clobetasol, withoutdoctor's prescription. We observe redness and a moon face, abuffalo hump, central obesity and hirsutism. Laboratory values revealed hypercholesterolemia, hypertriglyceridemia, elevationin liver enzymes and low early morning cortisol. To conclude,parents must be informed by physicians about the adverse effect of steroids and the should be avoided in very young infant(AU)

Neutrophilic dermatosis of the dorsal hands related to cocaine abuse

Abstract Neutrophilic dermatoses encompass a wide spectrum of diseases characterized by a dense infiltration mainly composed of neutrophils. Neutrophilic dermatosis of the dorsal hands is currently considered a localized variant of Sweet syndrome. Cocaine abuse has been related to a wide range of mucocutaneous manifestations, including neutrophilic dermatoses such as pyoderma gangrenosum. The authors of this study present a patient with neutrophilic dermatosis of the dorsal hands, in which cocaine abuse was identified as a probable trigger.

Giant perianal condyloma successfully treated with podophyllin at 25% in solid petrolatum

Purpose: Giant perianal condyloma (GPC) is a rare condition. The effective treatment is a multidisciplinary challenge; topical treatments are usually ineffective, and surgical resection has significant morbidity. Podophyllin at 25% in solid petrolatum (25%PSP) can be an effective treatment option for GPC. The aim of the present study was to assess its response and tolerability. Methods: This retrospective, single-center case series evaluated the clinical response of 14 patients with GPC treated with 25%PSP in a public hospital in Buenos Aires between December 2015 and December 2019. After obtaining a full history and performing a physical exam, the lesions were measured and photographed. Biopsies were performed to exclude malignancy, as well as exams to rule out pregnancy. Podophyllin at 25% in solid petrolatum was administered topically in cases of GPC and washed off by the patients at home after 4 hours. The patients underwent at least 4 weekly visits, which included interval history, photodocumentation of the lesions, and provider-applied 25%PSP. The response rate was assessed by comparingmeasurements and the overall decrease in volume of the GPC based on photos from the first and last sessions. Adverse outcomes were noted. Results: In total, 10 men, 3 women, and 1 transgender woman with GPC unresponsive to prior treatments and a mean age of 34.5 years were included. A total of 12 patients were immunosuppressed. All the perianal lesions were circumferential and measured between 8 cm and 20 cm. Overall, 7 patients had genital condyloma outside of the anus and perianus; the histology showed low-grade squamous intraepithelial lesions in all cases. While on treatment, 7 patients reported dermatitis, and 71% of the patients had 75% reduction in lesion size. Conclusions: Podophyllin at 25% in solid petrolatum is an effective, well-tolerated topical treatment option for GPC. (AU)

Peristomal dermatitis: treatment with green banana peel (Musa sapientum) powder / Dermatite periestomal: tratamento com pó de casca de banana verde (Musa sapientum)

Objective: To develop green banana peel (Musa sapientum) powder for the treatment of peristomal dermatitis, and to evaluate its effectiveness and healing time. Methods: A clinical, analytical and longitudinal study. In total, 44 volunteers of both genders, aged>18 years, with intestinal ostomy, who presented peristomal dermatitis, participated in the research. The sample was divided into two groups: the study group used a powder containing 10% of green banana peel, and the control group used ostomy powder. The research was approved by the Ethics in Research Committees (Comitês de Ética em Pesquisa, CEP, in Portuguese) under opinion n° 2.381.904. Results: The healing time of the study group was shorter than that of the control group (p=0.022). To analyze the results, we used the two-sample t-test (mean days until healing for both study groups). Conclusion: The powder containing 10% of green banana peel was developed, and effective healing of the peristomal dermatitis was observed. Compared to the ostomy powder, it presented a shorter healing time. (AU)
