ABSTRACT

Introdução: as queratoses actínicas são lesões pré-malignas com risco de transformação para carcinoma espinocelular invasivo. Não há correlação identificada entre classificação clínica e grau histológico destas lesões. Objetivos: correlacionar as características clínicas das queratoses actínicas dos antebraços e dorso das mãos com o grau de atipia histológica (Keratinocyte Intraepidermal Neoplasia); desenvolver e validar uma escala de gravidade clínica correlacionada ao grau histológico das queratoses actínicas. Métodos: estudo transversal com 162 queratoses actínicas avaliadas clinicamente quanto a diâmetro, eritema, infiltração, hiperqueratose e exulceração; biopsiadas 34 lesões com diferentes padrões. As características clínicas foram correlacionadas com o grau de atipia histológica e a expressão de p53 e Ki-67. Resultados: apenas o diâmetro das lesões correlacionou-se significativamente com o grau de atipia (p=0,04), e apenas o eritema, a hiperqueratose e o diâmetro correlacionaram-se com as marcações imuno-histoquímicas. Foi desenvolvido um escore clínico incluindo o diâmetro, a hiperqueratose e a exulceração, o qual se correlacionou significativamente com o grau de atipia (Rho de Spearman=0,43; p=0,01). Conclusões: desenvolveu-se um escore composto por diâmetro, hiperqueratose e exulceração correlacionado com o grau histológico das queratoses actínicas dos membros superiores.


Introduction: Actinic keratoses are premalignant lesions with a risk of transformation to invasive squamous cell carcinoma. There is no identified correlation between clinical classification and histological grade of these lesions. Objectives: To correlate the clinical characteristics of actinic keratoses of the forearms and back of the hands with the degree of histological atypia (Keratinocyte Intraepidermal Neoplasia); to develop and validate a clinical severity scale correlated with the histological grade of actinic keratoses. Methods: Cross-sectional study with 162 actinic keratoses clinically evaluated for diameter, erythema, infiltration, hyperkeratosis, and exulceration and 34 lesions with different patterns were biopsied. Clinical features were correlated with the degree of histological atypia and p53 and Ki-67 expression. Results: Only the diameter of the lesions was significantly correlated with the degree of atypia (p=0.04), and only the erythema, hyperkeratosis, and the diameter linked with the immunohistochemical markings. A clinical score including diameter, hyperkeratosis, and exulceration was developed, which associated significantly with the degree of atypia (Spearman's Rho=0.43; p=0.01). Conclusions: A score composed of diameter, hyperkeratosis, and exulceration correlated with the histological grade of actinic keratoses of the upper limbs was developed.

ABSTRACT

Introducción: se buscó analizar la prevalencia de enfermedades dermatológicas de la población de un asentamiento urbano precario próximo al vertedero municipal de Asunción (Paraguay), atendiendo a la exposición de las condiciones socioambientales. Materiales y métodos: estudio descriptivo y transversal con una muestra no probabilística intencional que incluyó a 77 personas de entre 5 meses y 76 años. Resultados: en el momento del examen físico, el 96.2 % de las personas presentó, al menos, una lesión cutánea, y el 79.2 %, una o más enfermedades infecciosas de piel; sin embargo, el 77.9 % no había recu-rrido a consulta médica. Las más sobresalientes fueron las micosis (35.1 %), las bacterianas (35.1 %) y las ectoparasitosis (27.3 %). Se identificó que la prevalencia de enfermedades bacterianas de piel apunta a una posible mayor exposición a condiciones adversas como: un clima subtropical de altas temperaturas y húmedo, una alta relación de convivientes en el hogar por dormitorio, problemas de provisión de agua y suelos de arena en los hogares, así como un sistema de evacuación de excretas deficiente, la presencia de animales con escasa vigilancia sanitaria, la proximidad a arroyos y cauces al aire libre depositarios de materia cloacal y el impacto recurrente de raudales los días de intensa lluvia. Conclusión: los resul-tados sugieren que la alta prevalencia de enfermedades cutáneas infecciosas podría relacionarse con una mayor exposición a condiciones socioambientales locales adversas, que son factores relevantes por tener en cuenta para mejorar la atención a la salud de las enfermedades dermatológicas de la población urbana que habita en un asentamiento urbano precario


Introduction: This study analyzes the prevalence of dermatological diseases in the population of a precarious urban settlement near the municipal landfill of Asunción (Paraguay), in relation to expo-sure to socio-environmental conditions. Materials and methods: descriptive, cross-sectional study with a non-probabilistic purposive sample that included 77 people aged between 5 months and 76 years. Results: at the time of physical examination, 96.2% of the people presented at least one skin lesion and 79.2% one or more infectious skin diseases, but 77.9% had not consulted a doctor. The most prominent were mycoses (35.1%), bacterial (35.1%) and ectoparasitoses (27.3%). It was identified that the preva-lence of bacterial skin diseases points to possible increased exposure to adverse conditions such as: a subtropical climate with high temperatures and humidity, a high ratio of people living in the household per bedroom, water supply problems and sandy soils in homes, as well as a deficient excreta disposal system, the presence of animals with poor sanitary surveillance, proximity to streams and open-air waterways that deposit sewage and the recurrent impact of floods on days of heavy rainfall. Conclusion:the results suggest that the high prevalence of infectious skin diseases could be related to increased exposure to adverse local socio-environmental conditions, which are relevant factors to be taken into to improve the health care of skin diseases in the urban population living in a slum settlement


Introdução: este estudo analisa a prevalência de doenças dermatológicas na população de um assen-tamento urbano precário próximo ao aterro sanitário municipal de Asunción (Paraguai) em relação à exposição às condições socioambientais. Materiais e métodos: estudo descritivo, transversal, com uma amostra não-probabilística de propósito que incluiu 77 pessoas com idade entre 5 meses e 76 anos. Resultados: no momento do exame físico, 96,2% das pessoas tinham pelo menos uma lesão de pele e 79,2% tinham uma ou mais doenças infecciosas de pele, mas 77,9% não tinham consultado um médico. As mais importantes foram micoses (35,1%), bacterianas (35,1%) e ectoparasitoses (27,3%). A preva-lência de doenças bacterianas da pele foi identificada como apontando para um possível aumento da exposição a condições adversas tais como: um clima subtropical com altas temperaturas e umidade, uma alta proporção de pessoas vivendo na casa por quarto, problemas de abastecimento de água e solos arenosos nas habitações, bem como um sistema de eliminação de excrementos deficiente, a presença de animais com vigilância sanitária deficiente, proximidade a riachos e cursos de água abertos que depositam águas residuais, e o impacto recorrente de enchentes em dias de chuvas fortes. Conclusão:Os resultados sugerem que a alta prevalência de doenças infecciosas de pele pode estar relacionada ao aumento da exposição a condições sócio-ambientais locais adversas, que são fatores relevantes a serem considerados para melhorar os cuidados com doenças de pele na população urbana que vive em uma favela

ABSTRACT

ABSTRACT Objective To analyze the pattern of triggering and exacerbation of dermatological diseases between March and July 2020 and to compare this pattern to the corresponding period of 2019. Methods This was a quantitative, descriptive, comparative and documentary study that was carried out through the retrospective analysis of medical records (March to July 2019 and 2020) of individuals assisted at a private dermatology practice service located in the southern area of the city of São Paulo (SP). Results We evaluated 992 medical consultations in 2019 and 1,176 in 2020. In 2020, we observed a significant increase in cases of telogen effluvium (276%), psoriasis (1,400%), atopic dermatitis (178%), seborrheic dermatitis (200%), herpes zoster (1,200%) and vitiligo (433%). All diseases had stress as a possible initial trigger. In addition, fragile nail syndrome and contact dermatitis, pathologies associated with behavioral measures, also had an important increase in the prevalence (6,400% and 5,500%, respectively). However, the number of aesthetic procedures decreased by approximately 54% during the pandemic period. Conclusion During the pandemic period, the pattern of incidence of dermatoses had changed compared with the previous year. An emphasis was observed on diseases triggered by a psychological component, as well as those pathologies that have behavioral measures as the main cause. For this reason, the impacts of COVID-19 is greater than only among those infected.

ABSTRACT

Considerando que las huellas dactilares son impresiones de las crestas epidérmicas de los dedos con un patrón único, irrepetible y permanente, estas son la base del método biométrico más empleado en la actualidad. Entre sus diversos usos destaca la identificación para múltiples actividades como acceder al trabajo o a teléfonos celulares, la operación de cuentas bancarias, las investigaciones criminales, etcétera. La ausencia o deterioro de las crestas epidérmicas, denominada adermatoglifia, impide la identificación por biometría dactilar. La adermatoglifia se origina por múltiples causas, incluyendo las enfermedades dermatológicas, lesiones traumáticas de los dedos, denervación, envejecimiento, quimioterapia, entre otras. Abordamos brevemente el origen, usos y sistemas para el registro de las huellas dactilares. El objetivo principal es enfatizar la existencia de personas con incapacidad para registrar sus huellas, una condición relevante por el riesgo potencial de discriminación, especialmente cuando el registro de las huellas es obligatorio.


Considering that fingerprints are impressions of the epidermal ridges of the fingers with a unique, unrepeatable, and permanent pattern, they are the basis of the biometric identification method most used today. Among its various uses stand out identification for multiple activities such as authentication to access work and cell phones, operation of bank accounts, criminal investigations, etc. The absence or deterioration of the epidermal ridges, called adermatoglyphia, prevents identification by finger biometrics. Adermatoglyphia originates from multiple causes, including several skin diseases, traumatic injuries of the fingers, denervation, aging, chemotherapy, among others. The origin, uses, and systems for fingerprints verification are briefly addressed here. The main objective is to emphasize the existence of people with fingerprint verification failure, a relevant condition due to the potential risk of discrimination, especially when fingerprint verification is mandatory.

ABSTRACT

Abstract Lipoid proteinosis is a rare autosomal recessive disease, characterized by hyaline deposits of PAS-positive material in tissues due to mutations in the ECM1 gene. This study evaluated the ultrastructure of the skin of a 6-year-old child affected by this condition. The light microscopy identified PAS-positive hyaline deposits, which were more intense in the papillary dermis. Scanning electron microscopy of the dermis showed a compact papillary dermis and fibrillar deposits in the middle dermis. Transmission electron microscopy clearly showed the deposition of fibrillar material in the dermis, forming clusters adherent to elastic fibers, between the collagen bundles and the collagen fibers, and also filling up the cytoplasm of dermal fibroblasts.

ABSTRACT

Abstract In addition to the infestations and bacterial infections reported in part I, the study of entomodermoscopy also involves descriptions of dermoscopic findings of a growing number of viral and fungal infections, among others. In this article, the main clinical situations in viral infections where dermoscopy can be useful will be described, that is in the evaluation of viral warts, molluscum contagiosum, and even in recent scenarios such as the COVID-19 pandemic. As for fungal infections, dermoscopy is particularly important, not only in the evaluation of the skin surface, but also of skin annexes, such as hairs and nails. The differential diagnosis with skin tumors, especially melanomas, can be facilitated by dermoscopy, especially in the evaluation of cases of verruca plantaris, onychomycosis and tinea nigra.

ABSTRACT

Abstract Dermoscopy is an essential in vivo diagnostic technique in the clinical evaluation of skin tumors. Currently, the same can also be said about its implications when approaching different clinical situations in Dermatology. A growing number of reports on dermatological scenarios and diseases have been published, in which dermoscopy has been of great diagnostic help. The term ‟entomodermoscopy" was coined to describe dermoscopic findings in skin infestations and also in dermatoses of infectious etiology. In part I of this article, the main dermoscopic descriptions of zoodermatoses and bacterial infections will be addressed. In many of them, such as scabies, pediculosis, myiasis, and tungiasis, it is possible to identify the pathogen and, consequently, attain the diagnosis more quickly and use the technique to follow-up therapeutic effectiveness. In other situations that will be described, dermoscopy can allow the observation of clinical findings with greater detail, rule out differential diagnoses, and increase the level of confidence in a clinical suspicion.

ABSTRACT

Resumen Objetivo: Este artículo tiene como objetivo realizar un análisis comparativo de la prevalencia de enfermedades dermatológicas, antecedentes en salud y medidas de protección de seguridad y salud en el trabajo entre la población recicladora y no recicladora que vive alrededor del vertedero municipal de la ciudad de Asunción, en Paraguay. Metodología: Estudio descriptivo y transversal, con una muestra no aleatoria intencional en cuatro microterritorios, que incluyó 40 personas de entre 15 y 76 años: 22 recicladores y 18 no recicladores. Resultados: Se encontró que los recicladores presentaron mayor prevalencia de enfermedades dermatológicas en el examen físico y en antecedentes de salud, entre los cuales se identificó un 63,7 % con tres o más lesiones en piel (en contraste con un 16,6 % de los no recicladores), y pronunciados porcentajes en enfermedades infecciosas cutáneas: micosis (50 %) y de origen bacteriano (31,8 %). En antecedentes cutáneos, los recicladores resultaron con mayores proporciones en heridas por corte (59,1 %), forúnculos (59,1%), tunga penetrans (40,9 %), larva migrans cutánea (36,4 %), heridas infectadas por corte (27,3 %), fotodaño (22,7 %), tinea pedis (13,6 %) y heridas por punción de jeringa (9,1 %). Estos reportaron también mayores porcentajes respecto a frecuentes problemas respiratorios, gastrointestinales, cefaleas y dolores musculoesqueléticos. Se constataron insuficientes medidas de protección de seguridad y salud en los trabajadores dedicados a la actividad del reciclado. Conclusión: Estos resultados sugieren un mayor potencial de exposición del grupo de recicladores a una variedad de fuentes de riesgos en salud relacionadas con las condiciones precarias de su actividad laboral, lo cual apunta a un desafío prioritario para la salud pública.


Abstract Objective: This article aims to perform a comparative analysis of the prevalence of dermatological diseases, past medical history and, safety and health conditions at work among a recycling and a non-recycling population living around the municipal landfill in Asunción, Paraguay. Methodology: A descriptive and cross-sectional study, with a non-random sample chosen intentionally in four micro-territories was carried out, which included 40 people aged between 15 and 76 years: 22 recyclers and 18 non-recyclers. Results: Recyclers showed a higher prevalence of dermatological diseases based on physical examinations and review of their past medical history; among them 63.7% were identified with three or more skin lesions (in contrast to 16.6% of non-recyclers) and high percentages of cutaneous infectious diseases: mycotic (50 %) and bacterial (31.8%). Regarding their past medical history of cutaneous diseases, recyclers reported cut wounds (59.1 %), boils (59.1%), tunga penetrans (40.9 %), cutaneous larva migrans (36.4 %), infected cut wounds (27.3 %), photodamage (22.7 %), tinea pedis (13.6 %) and puncture wounds (syringe) (9.1 %). They also reported frequent respiratory and gastrointestinal problems, headaches and musculoskeletal pain. Additionally, insufficient safety and health protection measures were found in workers engaged in recycling. Conclusion: These results indicate a greater exposure to a variety of risk factors related to the precarious work conditions of the recycling group, and this aspect becomes a challenge for public health as well.

ABSTRACT

Nevo epidérmico verrucoso inflamatório linear e diagnóstico diferencial com a psoríase linear: a respeito de um caso RELATO DE CASOMaria Isabel Muniz Zemero1, Maria Amélia Lopes dos Santos1, Alena Margareth Darwich Mendes1, Carla Andrea Avelar Pires1,O nevo epidérmico verrucoso inflamatório linear (NEVIL) é uma variedade clínica rara de nevo epidérmico verrucoso, que se manifesta no início da infância, como lesões inflamatórias de superfície ceratósica, que coalescem e se distribuem em faixa, acompanhando as linhas de Blaschko. Faz diagnóstico diferencial com a psoríase linear, sendo difícil a diferenciação, dado os aspectos clínicos e histopatológicos comuns aos dois, enfantizando-se a necessidade de conhecer as características específicas de cada um. O objetivo deste relato é demonstrar uma afecção relativamente rara, descrita em uma menina de 5 anos, evoluindo desde os primeiros dias de vida com placas papuloceratósicas dispostas linearmente, acompanhadas de sinais inflamatórios e áreas erosadas ocupando grandes lábios, períneo e face interna e superior da coxa esquerda. Também pápulas e placas ceratósicas na região cervical posterior e borda lateral externa da planta do pé esquerdo, ascendendo ao longo da região posterior deste membro. Os critérios clínicos e histopatológicos corroboram o diagnóstico de NEVIL na diferenciação com a psoríase linear, ressaltando a importância do estabelecimento de critérios/ ferramentas que auxiliem na diferenciação destas duas dermatoses visando agilizar o diagnóstico, otimizar o tratamento e minimizar o desconforto para esses pacientes. O acompanhamento a longo prazo dos portadores é sugerido pela possibilidade ainda que mínima de malignização do NEVIL. (AU)


Inflammatory linear verrucous epidermal nevus and differential diagnosis with linear psoriasis: about a caseCASE REPORTMaria Isabel Muniz Zemero1, Maria Amélia Lopes dos Santos1, Alena Margareth Darwich Mendes1, Carla Andrea Avelar Pires1,Inflammatory Linear Verrucous Epidermal Nevus (ILVEN) is a rare clinical variety of verrucous epidermal nevus that manifests in early childhood as inflammatory lesions of keratosis surface, which coalesce and spread in band, following Blaschko lines. It makes a differential diagnosis with Linear Psoriasis; it is difficult to differentiate them given the clinical and histopathological aspects common to both, emphasizing the need to know the specific characteristics of each. The purpose of this report is to demonstrate a relatively rare affection, expressed in a 5-year-old girl, evolving from the first days of life with papulokeratosic plaques arranged linearly, followed by inflammatory signs and eroded areas, placed linearly, overtaking labia majora, perineum, the inner and upper face of the left thigh. Also, the patient showed keratotic papules and plaques in the posterior cervical region and external lateral border of the left foot plant, ascending along the posterior region of this limb. The clinical and histopathological criteria corroborate the diagnosis of ILVEN in differentiation with linear psoriasis, emphasizing the importance of establishing criteria/instruments to assist in distinguishing these two dermatoses in order to expedite the diagnosis, to optimize the treatment and minimize patients' discomfort. Long-term follow-up of patients with this disease is suggested due to the possibility, albeit minimal, of ILVEN malignancy. (AU)

ABSTRACT

Abstract Glomus tumors are rare benign neoplasms arising from the neuromyoarterial structure called glomus body. They present as angiomatous papules, soft and painful, especially to cold and pressure. In general, they are solitary and affect the extremities, located mainly the subungual bed. Extradigital lesions are rare and can constitute a diagnostic challenge. This is the report of a patient with an extradigital lesion on the left arm, and its dermoscopic aspects, including angiomatous lagoons circumscribed by a pale halo, a structure not previously described in the two reports of extradigital glomus tumor with dermoscopic features, found in the literature.

ABSTRACT

Abstract Carney complex is a rare genodermatosis characterized by cardiac and cutaneous myxomas, among other tumors. In the majority of cases, cutaneous myxomas precede the diagnosis of cardiac myxomas, which are the main cause of death in these patients. Despite the fact that the diagnosis of cutaneous myxomas is histopathological, high-frequency ultrasonography plays an essential role in the differential diagnosis with other cutaneous and subcutaneous tumors. The authors of the present study describe, for the first time in the literature, the ultrasonographic features of both variants of cutaneous myxomas, superficial and subcutaneous, in a patient with a Carney complex.

ABSTRACT

Abstract Autoimmune bullous dermatoses are a heterogeneous group of diseases with autoantibodies against structural skin proteins. Although the occurrence of autoimmune bullous dermatoses during pregnancy is low, this topic deserves attention, since the immunological and hormonal alterations that occur during this period can produce alterations during the expected course of these dermatoses. The authors review the several aspects of autoimmune bullous dermatoses that affect pregnant women, including the therapeutic approach during pregnancy and breastfeeding. Gestational pemphigoid, a pregnancy-specific bullous disease, was not studied in this review.

ABSTRACT

Abstract The species of the Cryptococcus neoformans complex show different epidemiological patterns in the infection of immunosuppressed or immunocompetent individuals, and a common tropism peculiarity for the central nervous system. Primary cutaneous cryptococcosis is a rare clinical entity, with manifestations that are initially restricted to the skin through fungal inoculation, and the absence of systemic disease. The authors report in the present study the case of a 61-year-old immunocompetent man, with a rapidly evolving mucoid tumor on abrasions in contact with bird droppings on the forearm. The early identification of the polymorphic skin manifestations and treatment are crucial for the favorable prognosis of the infection, which can be life-threatening.

ABSTRACT

Abstract A 56-year-old male, HIV-positive, presented with a 3-day history of multiple indurated erythematous nodules with superficial and well-defined erosions on his right gluteus. Skin biopsy showed ballooning-necrotic keratinocytes and cultures were positive for herpes simplex 2. Genital herpes simplex infection recurrences may not be restricted to the anterior part of the genitalia and clinical presentation in the lumbar area or gluteus must be differentiated from varicella-zoster virus infection. Tumor-like presentation is a very rare manifestation of HSV cutaneous infection. It is important to take this morphological variant into consideration not to delay the diagnosis of a viral infection, especially in an immunosuppressed patient.

ABSTRACT

Abstract The study of skin, the science of dermatology, has undergone significant transformations throughout the centuries. From the first descriptions of skin diseases in Egyptian papyri and in Hippocratic writings to the first treatises on dermatology, important individuals and discoveries have marked the specialty. In the 18th and 19th centuries, the specialty consolidated itself as a field of medical study based on the first classifications of dermatoses, diagnostic methods, and drug treatments. In the 20th century, the scientific and technological revolution transformed dermatological practice, incorporating new therapeutic resources, as well as surgical and aesthetic procedures. In the face of such a vigorous process, it is important to provide a historical synthesis for the medical community to recognize and understand the origins that supported one of the most relevant specialties in the current medical scenario.

ABSTRACT

A vasculopatia livedoide é uma doença cutâneo-vascular que surge devido à oclusão trombogênica de vasos da derme. Apresenta-se por meio de máculas ou pápulas eritematosas e purpúricas, em membros inferiores, que podem levar à ulceração dolorosa crônica e recorrente. Com a evolução, pode haver cicatrização, o que leva ao aparecimento de áreas de fibrose e cicatrizes atróficas, irregulares e esbranquiçadas, dando nome à patologia. Relata-se o caso de uma paciente com vasculopatia livedoide de acometimento de membros inferiores.


Livedoid vasculopathy is a vascular skin disease resulting from thrombogenic occlusion of dermal blood vessels. It presents with erythematous, purpuric macules or papules on the lower limbs, which can lead to chronic and recurrent painful ulceration. With its progression, there may be scarring leading to the appearance of areas of fibrosis and atrophic, irregular, and whitish scars, which gave this name to the pathology. The case of a patient with livedoid vasculopathy affecting the lower limbs is reported.

Abstract Introduction: The most frequent clinical manifestations of Human Herpesvirus 6 (HHV-6) in children under 2 years of age are roseola-like skin lesions and sudden rash. In adults, the clinical manifestations associated with HHV-6 are highly variable and can overlap with other conditions. Objective: To present a case series of patients diagnosed with active HHV-6 infection, who showed neurological, dermatological and chronic fatigue manifestations. Materials and methods: An analysis of medical records of 6 patients who were diagnosed with active HHV-6 infection through molecular methods was performed. Results: 6 patients were diagnosed with active HHV-6 infection using molecular methods, who had common clinical manifestations such as fever, headache, depression, tiredness, loss of memory and concentration, fibromuscular pain, polyarticular pain, nonrestorative sleep, rash, ruby nevus, lichen planus and paresthesia. Conclusions: This case series highlights the importance of identifying active HHV-6 infection through molecular methods and creating awareness in the medical community of the role that the virus plays on the development of diverse pathologies.

ABSTRACT

Objective:To deliver understanding of the latest research progress on clinical trials and approval of dermatological drugs in China in 2020.Methods:A registration and information disclosure platform for drug clinical studies and a query system for domestic and imported drugs in the National Medical Products Administration of China were searched for registered clinical trials and approved dermatological drugs, respectively. The number and stages of clinical trials, indications and classification of involved products, and listed dermatological drugs in 2020 were summarized and depicted.Results:There were 157 dermatological drug trials registered in China in 2020, accounting for 6.16% of all the 2 548 clinical drug trials, including 127 (80.9%) initiated by Chinese pharmaceutical enterprises and 25 (15.9%) international multicenter trials. Among the 127 drug trials initiated by Chinese pharmaceutical enterprises, bioequivalence trials were mostly common, accounting for 55.9% (71/127) . Compared with global pharmaceutical enterprises, domestic pharmaceutical companies initiated significantly decreased proportions of international multicenter trials (1.9% [3/157] vs. 14.0% [22/157], P < 0.001) , but significantly increased proportions of phaseⅠclinical trials and bioequivalence trials (24.4% [31/127] vs. 10.0% [3/30], 55.9% [71/127] vs. 0, respectively, both P < 0.001) . Totally, 90 kinds of dermatological drug were involved in all the trials, psoriasis, atopic dermatitis and melanoma were the most common indications, and innovative drugs accounted for 53.3% (48/90) ; the proportion of innovative drugs was significantly lower in domestic pharmaceutical companies than in global pharmaceutical companies (43.2% [32/74] vs. 16/16, P < 0.001) . In addition, 28 dermatological drugs developed by 22 pharmaceutical companies were approved in China in 2020, of which 21 drugs were developed by domestic pharmaceutical companies. Conclusion:Clinical drug trials carried out by domestic pharmaceutical companies mostly focus on generic drugs, and it is still necessary for domestic pharmaceutical companies to further improve the innovation ability.

ABSTRACT

A 2-year- and 2-month-old girl developed recurrent eczema-like rashes 7 days after birth, followed by the occurrence of poikiloderma and hair loss. Cholestasis occurred at the age of 1 month and 10 days, which was improved but serum transaminase levels were elevated after 4 months. The patient usually presented with slight sweating, heat intolerance, and delayed gross motor development. Skin examination showed generalized mottled hypo- and hyper-pigmented patches, especially in the exposed areas, and sparse hair and eyebrows. Her parents had no similar clinical manifestations. Whole-exome sequencing showed a mutation c.1883G>A (p.Ser628Asn) in the FAM111B gene in the child, which was not found in her parents. According to the typical skin lesions, abnormal liver function and genetic testing results, this patient was diagnosed with hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis, and the mutation c.1883G>A in the FAM111B gene may be the cause of the patient′s clinical manifestations. The patient received hepatoprotective therapy, sun screen intervention, rehabilitation training, etc. After 10-month follow-up, the patient still presented with skin lesions and elevated transaminases, but without other discomforts.

ABSTRACT

Photodynamic therapy (PDT) is the first-line treatment of some intractable skin diseases, such as actinic keratosis, condyloma acuminatum and moderate to severe acne vulgaris. In clinical practice, radiation parameters and light sources are important for the efficacy of PDT. This review focuses on the selection of radiation parameters and light sources for PDT in terms of the wavelength and type of light sources and dose of radiation, and summarizes research progress in new light sources for PDT.
