ABSTRACT
La piel y sus anexos tienen amplia relación con todos los órganos y sistemas. Los cambios presentes en estos pueden ser el primer hallazgo en un paciente con enfermedad hepática, encontrándose hasta en el 20 % de los casos, por lo que las manifestaciones extrahepáticas adquieren importancia, y aunque muchas de estas no son específicas, algunos marcadores dermatológicos pueden ayudar al diagnóstico de la enfermedad y se pueden correlacionar con su severidad. El desarrollo de las lesiones cutáneas en los pacientes con cirrosis hepática se genera principalmente por hipertensión portal y exceso de estrógenos circulantes, por lo tanto, su tratamiento se basa en el manejo de la patología hepática subyacente. En el presente artículo se hace una revisión de la literatura y se describe un amplio espectro de manifestaciones dermatológicas asociadas a cirrosis hepática, con sus características y etiopatogénesis, siendo las más frecuentes la ictericia, el prurito, los nevus en araña, el eritema palmar, las venas en cabeza de Medusa, y los cambios de uñas y del vello, entre otras.
The skin and its annexes have a broad relationship with all organs and systems. Changes present in these can be the initial finding in a patient with liver disease, occurring in up to 20% of cases, therefore the extrahepatic manifestations become important, and although many of these are not specific, some dermatological markers can help in the diagnosis of the disease and may correlate with its severity. The development of cutaneous lesions in patients with liver cirrhosis is mainly generated by portal hypertension and excess of circulating estrogens, therefore their treatment is based on managing the underlying liver pathology. This article reviews the literature and describes a wide range of dermatological manifestations associated with liver cirrhosis, with their characteristics and etiopathogenesis, being the most frequent jaundice, pruritus, spider nevus, palmar erythema, caput Medusae veins, nail and hair changes, among others.

Abstract Background: Pemphigus constitutes a group of autoimmune bullous diseases. A reduction in the incidence of endemic pemphigus foliaceus and an increase in pemphigus vulgaris has been described, but there are no studies in Minas Gerais that address the subject. Objective: To describe the epidemiological and clinical profile of patients with pemphigus treated at the Dermatology Service of a public University Hospital in the state of Minas Gerais, Brazil. Methods: An observational, descriptive, and cross-sectional study was carried out of cases of endemic pemphigus foliaceus and pemphigus vulgaris, for a period of six months. A questionnaire was filled out with epidemiological and clinical data on the disease. Results: A total of 122 patients were included in the study, 64 with endemic pemphigus foliaceus and 58 with pemphigus vulgaris. When comparing patients with endemic pemphigus foliaceus and those with pemphigus vulgaris, a statistical difference was observed between the median age of initial disease manifestation (p = 0.001), patient occupation (p = 0.010), area of residence (p = 0.000), forests (p = 0.000) and rivers/streams close to the dwelling (p = 0.001) and the number of systemic medications required to control the disease (p = 0.002). When comparing patients with endemic pemphigus foliaceus to those evaluated in a study carried out at the same service in 2008, there was a statistical difference in the area of residence (p = 0.030). Study limitations: The assessed population comes from a tertiary care service that is not a reference for the entire state. Conclusions: Patients with endemic pemphigus foliaceus and pemphigus vulgaris maintain statistically significant differences regarding their main variables in the literature, such as age and area of residence. Historically, there has been a reduction in cases of endemic pemphigus foliaceus and an increase in cases of pemphigus vulgaris in this population.
ABSTRACT
ABSTRACT BACKGROUND: The prevalence of chronic kidney disease (CKD) has increased in the recent decades, along with the number of patients in the terminal stages of this disease, requiring transplantation. Some skin disorders are more frequent in patients with CKD and in renal transplant recipients (RTR). OBJECTIVES: To evaluate the frequency of skin diseases in RTR and patients with CKD receiving conservative treatment. DESIGN AND SETTING: This observational cross-sectional study recruited consecutive patients with CKD and RTR from a nephrology clinic at a teaching hospital in Brazil between 2015 and 2020. METHODS: Quantitative, descriptive, and analytical approaches were used. The sample was selected based on convenience sampling. Data were collected from dermatological visits and participants' medical records. RESULTS: Overall, 308 participants were included: 206 RTR (66.9%, median age: 48 years, interquartile range [IQR] 38.0-56.0, 63.6% men) and 102 patients with CKD (33.1%, median age: 61.0 years, IQR 50.0-71.2, 48% men). The frequency of infectious skin diseases (39.3% vs. 21.6% P = 0.002) were higher in RTR than in patients with CKD. Neoplastic skin lesions were present in nine (4.4%) RTR and in only one (1.0%) patient with CKD. Among the RTR, the ratio of basal cell carcinoma to squamous cell carcinoma was 2:1. CONCLUSIONS: This study revealed that an increased frequency of infectious skin diseases may be expected in patients who have undergone kidney transplantation. Among skin cancers, BCC is more frequently observed in RTR, especially in those using azathioprine.
ABSTRACT
ABSTRACT Objective: The objective of this study was to describe a case of cutaneous lichen planus (LP) that appeared following COVID-19 infection. Case description: We report a case of extensive cutaneous classic familial LP in a 4-year-old male child after an asymptomatic serologically confirmed COVID-19 infection. The patient developed intensely itchy, purple, flat-topped papules and plaques, mainly on the dorsal surface of the hands, feet, forearms, and shins. Histopathological examination of the skin biopsy showed vacuolar and apoptotic degeneration of the basal cell layer with a band-like lymphocyte infiltrate at the dermo-epidermal junction and confirmed the diagnosis of LP. Comments: LP could be considered among the differential diagnoses of pediatric post-COVID inflammatory skin lesions, either in the patients recovering from COVID-19 infection or in the suspicious asymptomatic cases in close contact with COVID-19-infected patients.
RESUMO Objetivo: Descrever um caso de líquen plano cutâneo (LP) após infecção por COVID-19. Descrição do caso: Relatamos um caso de LP familiar clássico extenso cutâneo em uma criança de quatro anos de idade após uma infecção por COVID-19 assintomática e sorologicamente confirmada. O paciente desenvolveu pápulas e placas intensamente pruriginosas, roxas e achatadas, principalmente na superfície dorsal das mãos, pés, antebraços e canelas. O exame histopatológico da biópsia de pele mostrou degeneração vacuolar e apoptótica da camada basal com infiltrado de linfócitos em faixa na junção dermoepidérmica e confirmou o diagnóstico de líquen plano. Comentários: O líquen plano pode ser considerado entre os diagnósticos diferenciais de lesões cutâneas inflamatórias pós-COVID pediátricas, tanto em pacientes em recuperação de infecção por COVID-19 quanto em casos assintomáticos suspeitos em contato próximo com pacientes infectados por COVID-19.

El síndrome de Sweet es un tipo de dermatosis neutrofílica infrecuente, caracterizado por un cuadro febril agudo con aparición de lesiones en piel tipo pápulas y placas eritematosas y dolorosas, con neutrofilia periférica acompañante, que mejora con el uso de corticoides. Se presenta el caso de una paciente de 22 años, con vitíligo como enfermedad de base, que acude por un cuadro de 1 semana de evolución de sensación febril no graduada y aparición insidiosa de lesiones en piel foto expuesta. Se realizó estudios laboratoriales e histopatológicos llegando al diagnóstico de síndrome de Sweet. Con los resultados de los estudios paraclínicos se inició tratamiento con corticoides sistémicos y tópicos con excelente respuesta.
Sweet syndrome is a rare type of neutrophilic dermatosis, characterized by an acute febrile picture with the appearance of painful erythematous papules and plaques on the skin, with accompanying peripheral neutrophilia, which improves with the use of corticosteroids. The case of a 22-year-old patient, with vitiligo as the underlying disease, is presented. She attended for a 1-week history of ungraded feverish sensation and insidious appearance of lesions on photo-exposed skin. Laboratory and histopathological studies were carried out, leading to the diagnosis of Sweet syndrome. With the results of the paraclinical studies, treatment with systemic and topical corticosteroids was started with an excellent response.
ABSTRACT
Background: The prevalence of skin diseases has increased over the last few decades, and they contribute to a significant burden on health-care systems across the world. Aims/Objective: This report looks at the burden of skin and subcutaneous diseases in terms of years lived with disability and age-standardised years lived with disability in India using the Global Burden of Disease Study results from 2017. Methods: Data were obtained from the Global Burden of Disease online interactive tool. Updated estimates of the world’s health for 359 diseases and injuries and 84 risk factors from 1990 to 2017 are available in this interactive tool. Results: Years lived with disability due to skin and subcutaneous diseases accounted for 4.02% of the total years lived with disability in India in 2017. There was an increase of 53.7% in all age standardised years lived with disability for all the skin and subcutaneous diseases from 1990 to 2017. Among skin and subcutaneous diseases, dermatitis contributed maximum years lived with disability (1.40 million; 95% uncertainty interval, 0.82–2.21) in 2017, followed by urticaria (1.02 million; 95% uncertainty interval, 0.06–1.44) with percentage increases of 48.9% and 45.7% respectively. Conclusion: The burden due to infectious skin diseases (e.g., scabies, fungal skin disease and bacterial skin disease) and non-infectious diseases (e.g., dermatitis, urticaria and psoriasis) has increased over the past three decades, however the age-standardised years lived with disability for leprosy, scabies, fungal infections, sexually transmitted infections and non-melanoma skin cancer (basal cell carcinoma) has decreased. The high burden of skin and subcutaneous diseases demand that they be given due importance in the national programmes and health policy of India.
ABSTRACT
Background: Skin diseases occur in all age groups in developed and developing countries. Various types of skin diseases are found worldwide and depend on factors like environment, surrounding ecology, dietary habits, socioeconomic status, mental health, and literacy. Health-related quality of life (HRQOL) improves after treatment or cure of the diseases. Objectives: To estimate the pattern of skin disease. To find out the quality of life and association of skin disease with sociodemographic factors among patients. Methods: This observational cross-sectional study was done in skin OPD at the tertiary care center, Banda district of Uttar Pradesh, India from May 2022 to July 2022. All patients who attended to skin OPD during study period were included in the study after taking informed verbal consent. Results: Skin diseases had further divided in subcategories which were infectious conditions, pigmentary disorders, inflammatory dermatoses, miscellaneous skin conditions, benign tumor and other lesions with their percentage 44.8, 10.5, 28.6, 7.1, 2.9 and 6.2%, respectively in this study Classes of DQLI where major portion of patients (49.52%) were in ‘Small effect on patient’s life’ category. The relation of age, religion, education and member of household with history of skin disease were found to be highly statistically significant. Conclusion: Infectious skin diseases were found more common in study area. Male populations were more commonly affected. Skin diseases were more common in age group of 18–60 years. Study participants showed no predominant effect on quality of life. But small effect class had major effect on participant’s quality of life.
ABSTRACT
Introduction: The present report describes the case of a 12-year-old patient with 17-year follow-up who was previously diagnosed with Papillon-Lefèvre Syndrome (PLS), which is a rare autosomal recessive irregularity in the cathepsin C gene (CTSC) characterized by palmoplantar hyperkeratosis and premature loss of primary and permanent teeth. Case Report: A specific mutation in the c.203 T > G gene inducing loss of function leading to PLS was detected, as was a mutation in the HLA-DRB1*11 allele, which is associated with this syndrome. There is no consanguinity of the parents, and the siblings are entirely healthy. Early identification of the main characteristics of this syndrome is imperative. Accurate diagnosis by genetic analysis allows differential diagnoses and timely comprehensive dental treatment. Conclusions: Additionally, it allows consultation with a dermatologist to maintain or improve the quality of life of patients with this condition due to progressive worsening and severity of the main physical manifestations. Keywords: Papillon-Lefevre Disease; Keratoderma, Palmo-plantar; Cathepsin C; Periodontitis; Skin Diseases, Genetic; Case reports
Introducción: El presente reporte describe el caso de un paciente de 12 años de edad con 17 años de seguimiento a quien previamente se le diagnosticó Síndrome de Papillon-Lefèvre (PLS), el cual es una rara irregularidad autosómica recesiva en el gen de la catepsina C (CTSC) caracterizada por hiperqueratosis palmoplantar y pérdida prematura de dientes primarios y permanentes. Reporte de Caso: Se detectó una mutación específica en el gen c.203 T > G que induce pérdida de función que conduce a PLS, así como una mutación en el alelo HLA-DRB1*11, que se asocia a este síndrome. No presenta consanguinidad de los padres, padres y hermanos totalmente sanos. La identificación temprana de las principales características de este síndrome es imperativa. El diagnóstico certero por análisis genético permite diagnósticos diferenciales y tratamientos odontológicos integrales oportunos.

La sarcoidosis es una enfermedad granulomatosa sistémica de causa desconocida, con mayor prevalencia en el sexo femenino, entre los 20 a 40 años de edad; caracterizada por la formación de granulomas no caseificantes en distintos órganos. La afectación cutánea de forma exclusiva es rara, pues se describe solo en el 4-5 % de los pacientes, ya que las lesiones en piel pueden aparecer antes o después del compromiso sistémico, o bien coincidir con este. Se presenta el caso de una paciente de 35 años con lesiones en piel de cuatro años de evolución. Considerando el cuadro clínico y la histopatología, se concluyó con el diagnóstico de sarcoidosis cutánea, crónica y asintomática. Se trata de una enfermedad muy polimorfa en sus manifestaciones cutáneas, lo cual la convierte en una gran simuladora, y su diagnóstico constituye un reto para el dermatólogo.
Sarcoidosis is a systemic granulomatous disease of unknown cause, with a higher prevalence in females, between 20 and 40 years of age; characterized by the formation of non-caseating granulomas in different organs. Exclusive skin involvement is rare, as it is described in only 4-5% of patients, since skin lesions may appear before or after systemic involvement, or coincide with it. The case of a 35-years-old patient with skin lesions of four years of evolution is presented. Considering the clinical case and histopathology, the diagnosis of chronic and asymptomatic cutaneous sarcoidosis was concluded. It is a very polymorphic disease in its skin manifestations, which makes it a great simulator, and its diagnosis constitutes a challenge for the dermatologist.
ABSTRACT
Objetivo: Determinar las características clínicas y demográficas de los pacientes con lesiones de piel atendidos en un hospital general de Trujillo, Perú. Material y métodos: Estudio transversal, descriptivo, observacional y retrospectivo. Se hizo la revisión microscópica de 385 biopsias de piel de los archivos de Patología y de las historias clínicas de pacientes atendidos en el Hospital del Belén de Trujillo, durante el periodo comprendido entre enero del 2018 y diciembre del 2019. Resultados: La lesión más frecuente fue el carcinoma basocelular, localizado en alguna parte del rostro y de presentación mayor a edades de 60 años o más. En segundo lugar, carcinoma epidermoide. Las lesiones malignas afectaron al 66,7% de pacientes entre 55 y 79 años, con edad promedio de 67 años. En su mayoría (65,8%) fueron varones desocupados. De las lesiones benignas, la más frecuente fue el quiste de inclusión epidérmica y se ubicó en el tronco de varones entre 20 y 24 años. En segundo lugar, el pilomatrixoma se ubicó en los miembros superiores de menores de 10 años. Afectaron al 59,6%, entre los 30 y 54 años, con edad promedio de 44,1 años. En su mayoría (63,7%), se reportaron como ama de casa. Procedieron en su mayor parte de los distritos de Trujillo. No fue posible establecer el agente injuriante. Conclusiones: En personas de piel trigueña o cobriza, las lesiones tanto benignas como malignas tuvieron un patrón de presentación similar a la de otros estudios, tanto en localización, grupo etario y sexo. La procedencia y la ocupación no fueron contributorias.

Resumen La pitiriasis liquenoide varioliforme aguda (PLEVA) pertenece a un grupo de enfermedades categorizadas como pitiriasis liquenoides, junto con la enfermedad febril úlcero-necrótica de Mucha-Habermann y la pitiriasis liquenoide crónica (PLC). Se caracteriza por la aparición aguda de múltiples pápulas eritemato-violáceas con posterior necrosis, discromía residual y cicatrices varioliformes. Dentro de las teorías patogénicas propuestas se encuentra el posible papel de agentes infecciosos, trastornos linfoproliferativos, complejos inmunes e incluso, asociación a medicamentos. Se presenta un casode una mujer adulta con un cuadro típico de PLEVA con confirmación histopatológica, cuyas lesiones aparecieron posteriormente al inicio de eritropoyetina.
Abstract Pityriasis lichenoides et varioliformes acuta (PLEVA) is part of a group of diseases clustered as pityriasis lichenoides, next to febrile ulceronecrotic Mucha-Habermann disease and pityriasis lichenoides chronica. It's characterized by a sudden onset of multiple erythematous and violaceous papules which develop necrosis, leaving residual dyschromia and varioliform scars. It's been hypothesized the possible role of infectious agents, lymphoproliferative diseases, immune complexes and drugs. We present the case of a woman with a typical PLEVA with histopathological confirmation, whose lesions appeared after therapy with erythropoietin.
ABSTRACT
La leishmaniasis resulta una enfermedad infectocontagiosa causada por un protozoo del género Leishmania. Esta constituye un problema de salud importante para diversas regiones de América Latina. El aislamiento social impuesta a raíz de la pandemia de COVID-19 favoreció que disminuyera la incidencia de esta entidad, pero las actividades sociales de la normalidad se retomaron paulatinamente, imponiéndose que se retomen las medidas de seguimiento y control correspondientes.
Leishmaniasis is an infectious disease caused by a protozoan of the genus Leishmania. Leishma-niasis constitutes a significant health problem for various regions of Latin America. The social isolation imposed because of the COVID-19 pandemic favored a decrease in the incidence of this entity. However, regular social activities were gradually resumed, imposing the correspon-ding monitoring and control measures.

ABSTRACT
O filtrado de fermentação, (FF), um subproduto de leveduras rico em nutrientes, é usado cosmeticamente no leste da Ásia desde a década de 1970. Revisamos sistematicamente os efeitos deste ativo tópico na saúde da pele e determinamos as limitações nos estudos disponíveis. A literatura recente mostrou evidências na redução do tamanho dos poros, e tambem da aspereza, hiperpigmentação e vermelhidão. No entanto, esses estudos são limitados em eficácia devido ao pequeno tamanho da amostra, muitas variáveis e capacidade limitada de validação externa. Devido ao aumento de produtos cosméticos contendo esse ingrediente, é necessária uma análise crítica da literatura disponível e futura para evitar a desinformação do consumidor
Ferment filtrate (FF), a by-product of nutrient-rich yeast, is believed to be used cosmetically in East Asia since the 1970s. We systematically reviewed the topical effects of ferment filtrate on skin health and determined limitations in the available studies. Recent literature has shown evidence in reducing the baseline fluctuation of pore size, roughness, hyperpigmentation, and redness. However, these studies are limited in efficacy due to their small sample size, their confounding variables, and their limited generalizability. Because of the increase of cosmetic products containing this ingredient, critical analysis of the available and future literature is necessary to prevent consumer misinformation.
ABSTRACT
Introducción: Se denomina ántrax a la infección de varios folículos pilosos contiguos y es provocada por gérmenes patógenos muy invasivos. Es causado, generalmente, por el Staphylococcus aureus y puede tener repercusión sistémica. Los factores de riesgo para desarrollar esta lesión son: diabetes, obesidad, falta de higiene, inmunosupresión, hiperhidrosis, dermatitis preexistentes. Objetivo: Presentar un paciente con diagnóstico de ántrax gigante. Caso clínico: Paciente femenina de 66 años de edad, con antecedentes de diabetes mellitus tipo 2 en tratamiento, que asistió al servicio de Cirugía General por presentar una picadura de insecto en la región inferior de la espalda, la cual fue tratada en el área de salud con antimicrobianos y no resolvió. Se ingresó con el diagnóstico de ántrax gigante y con la administración de anestesia general endovenosa se realizó necrectomía. El postoperatorio transcurrió sin complicaciones y egresó a los siete días. Conclusiones: La rápida atención médica fundamentada en la administración de antimicrobianos de amplio espectro de forma parenteral, las curas locales y el seguimiento ininterrumpido en consulta externa de la paciente con ántrax gigante, asegura la eficacia del tratamiento quirúrgico con total recuperación, sin tener que aplicar injertos.
Introduction: Anthrax is the name given to the infection of several contiguous hair follicles and is caused by highly invasive pathogenic germs. It is generally caused by Staphylococcus aureus and can have systemic repercussions. The risk factors for developing this lesion are: diabetes, obesity, lack of hygiene, immunosuppression, hyperhidrosis, pre-existing dermatitis. Objective: To make the clinical presentation of a patient diagnosed with giant anthrax. Case report: This is a 66-year-old woman, with a history of type 2 diabetes mellitus under treatment, who attended the General Surgery service for presenting an insect bite in the lower region of the back, which was treated in the health area with antimicrobials and did not resolve. She was admitted with a diagnosis of giant anthrax and with the administration of general intravenous anesthesia, a necrectomy was performed. The postoperative period was uncomplicated and she was discharged after seven days. Conclusions: The immediate medical care based on the parenteral administration of broad-spectrum antimicrobials, local cures and uninterrupted follow-up in the outpatient clinic of the patient with giant anthrax, ensures the effectiveness of the surgical treatment with full recovery, without having to apply grafts.
ABSTRACT
ABSTRACT A male infant presented with progressive jaundice immediately after birth. Fecal acholia and choluria associated with extensive bullous skin lesions in his trunk, abdomen, and upper and lower limbs developed during phototherapy. Several diagnostic hypotheses were presented, including neonatal porphyria, hemochromatosis, Alagille syndrome, and neonatal lupus. A 24-hour urine sample for the dosage of urinary porphyrins was collected, showing high results (1823.6µg in 100mL). At 50 days of life, fluorescence spectroscopy using a Wood's lamp revealed simultaneous bright red fluorescence of urine-stained diapers and sample blood. A definitive diagnosis of congenital erythropoietic porphyria was made following identification of a mutation of the uroporphyrinogen synthetases III gene on genetic testing. The patient was subsequently maintained in a low light environment since then, resulting in improvement of the lesions. Congenital erythropoietic porphyria is a disease of the group of porphyrias that presents shortly after birth with blistering occurring in regions exposed to the sun or other ultraviolet light. Atrophic scars, mutilated fingers, and bright red fluorescence of the urine and teeth may also be observed. There is no specific treatment, and prophylaxis comprising a total avoidance of sunlight is generally recommended. A high degree of suspicion is required for diagnosis. An early diagnosis can lead to less damage. Here, we present the case of a newborn with congenital erythropoietic porphyria diagnosed after presenting with bullous lesions secondary to phototherapy.
ABSTRACT
Abstract Background Although traditionally used for the diagnosis of skin tumors, in the past few years dermoscopy as a clinical diagnostic aid for inflammatory and infectious skin manifestations has also received more and more attention. The clinical variability of cutaneous sarcoidosis (CS) often makes its correct diagnosis challenging. Dermoscopy can be used as an auxiliary examination method. Objective Our aim was to evaluate the role of dermoscopy in the diagnosis and differential diagnosis of CS. Methods This was a retrospective analysis of 39 CS clinical and dermoscopic images collected in the Department of Dermatology, Huashan Hospital Affiliated with Fudan University from August 2013 to February 2021. Results Retrospective dermoscopic evaluation revealed small grouped, translucent orange globular structures in all 39 cases. Variable diameter linear vessels were found in 38 cases. A central scar-like area was seen in 26 cases. Bright white streaks were seen in 30 cases. The follicular plugs were seen in 15 cases. Study limitations First, the number of cutaneous sarcoidosis cases the authors collected is small. Second, due to the lack of a control group, the sensitivity and specificity of the proposed criteria were not calculated. Finally, since our study mainly includes suspicious lesions that were biopsied for diagnostic purposes, there may be a selection bias. Conclusion Lesions showing on dermoscopy grouped translucent orange ovoid structures associated with linear vessels should raise the suspicion of CS. Central scar-like areas and bright white streaks are also helpful in the diagnosis of CS.
ABSTRACT
Abstract Background Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are subtypes of pemphigus with distinct clinical and laboratory features. The transition between these two subtypes has rarely been reported previously. Methods The data of PV patients who exhibited clinical and immunoserological transition to PF during the follow-up period were retrospectively evaluated regarding their demographical, clinical, and laboratory characteristics. Results Among 453 patients diagnosed with PV, 13 (2.9%) patients exhibited clinical and immunoserological transition from PV to PF. The mean age of PV patients at the time of diagnosis was 39.8 ± 14.7 (19‒62) years and 7 (53.8%) of them were female. These patients showed clinical and immunoserological transition from PV to PF after a period ranging from 4 months to 13 years (mean 36.2 ± 41 months). In addition to typical clinical features of PF, all patients had positive anti-desmoglein-1 and negative anti-desmoglein-3 antibody levels after the clinical transition had occurred without any mucosal involvement. During a mean 7.8 ± 5.8 (2‒21) years of follow-up period after the transition from PV to PF, only one female patient had experienced a re-transition to PV characterized by a relapse of disease involving mucosal surfaces with positive anti-desmoglein-3 antibody levels following a 5-year period of remission period without treatment. Study limitations Single-center study with a retrospective study design. Conclusion Our series is the largest group of patients reported to show the transition from PV to PF to date with a long follow-up period. The reason behind the disappearance of anti-desmoglein-3 antibodies and the pathogenesis of this phenomenon is not yet elucidated.
ABSTRACT
Abstract Background In hospital settings, dermatology can offer substantial clinical support for the diagnosis and management of skin conditions, reducing morbidity and mortality. Thus, the study aimed to analyze the profile of referrals and consultations performed by the Dermatology Service of the Santa Casa de Misericordia de Porto Alegre, from August 2018 to January 2020. Methods This study is descriptive, quantitative, and retrospective, conducted through data collection and review of medical records and referrals. The variables included were clinical data of referrals, in-patients profiles, dermatological diagnoses, complementary exams, therapeutic conduct, and recommended follow-ups. Results A total of 1020 referrals were analyzed, which resulted in 641 consultations (328 men, 313 women). The most prevalent skin disease groups were 'Dermatitis and Eczema' (33.1%) and 'Other infectious skin diseases (21.8%), while the most frequent ICD-10 were 'Drug eruptions - L27' (9.9%) and 'Other and unspecified dermatitis - L30' (6.6%). Corticoids were the most recommended treatments (27.7%), followed by antifungals (13.1%). 'Consultation Discharge' (44%) and 'Outpatient' Dermatology follow-up (27%) were the most frequent causes for ending consultation. Study limitations Among the study limitations, the authors highlight its retrospective nature, with data analysis based on referrals and medical records, which may present inaccurate or incomplete information. In addition to this, the study may demonstrate a certain degree of subjectivity due to the review and interpretation process conducted by the researchers. However, the definition of objective criteria based on previous studies attenuates such possible bias. Furthermore, considering that the Dermatology teams are composed of a preceptor dermatologist and residents, the established diagnoses were not submitted to third-party verification, except in the cases of skin biopsies and cultures. Thus, the professional's experience and skills may have influenced the dermatological diagnoses. Conclusions These findings underlie the importance of Dermatology in hospital assistance, contributing to the management of a wide range of skin conditions.
