ABSTRACT
BACKGROUND/OBJECTIVE: Psoriatic arthritis (PsA) is a chronic inflammatory illness. Approximately, 15% of psoriasis patients have undiagnosed PsA. In Mexico, we found no related studies. Our objective was to investigate the clinical-epidemiological characteristics of PsA in psoriasis patients in western Mexico. METHODS: A cross-sectional study including Mexican patients with clinical and histopathological diagnosis of psoriasis. Physical examination, rheumatoid factor analysis and radiographies of axial and peripheral skeleton were performed. The prevalence of PsA using the CASPAR criteria, age, sex; clinical variants of PsA, psoriasis type and the Psoriasis Area and Severity Index (PASI), were assessed. Descriptive and inferential statistics were used. RESULTS: Of 90 patients with psoriasis, 48 met the criteria for PsA, with a prevalence of 53%, and average age of 50 ± 15 years. Predominating were, the female sex in 29 (60%), the axial variant of PsA in 24 (50%), and psoriasis plaques in 40 (83%). The average PASI was 12 ± 11. All cases were rheumatoid factor negative. These variables were not significantly different when comparing subjects with and without PsA, except for the female sex (60% vs. 7%; P < 0.001). CONCLUSIONS: Patients with psoriasis should intentionally be evaluated jointly Dermatologists and Rheumatologists searching joint involvement given the high prevalence of PsA previously undiagnosed.

BACKGROUND: The diagnostic approaches and therapeutic strategies of atopic dermatitis (AD) are generally inconsistent among physicians and health institutions. OBJECTIVE: To develop a consensus statement among experts to reduce the variations in practice regarding the diagnosis and treatment of patients ≥ 12 years with AD to improve their care. METHODS: Systematic literature search in PubMed and GREAT. With methodological support and using the Delphi method, a formal consensus was developed among 16 experts in Dermatology and Allergology, based on the current evidence and its applicability in the Mexican context. Apart from intense electronic communication, several issues of disagreement were discussed in two face-to-face meetings. RESULTS: The clinical experts reached consensus on 46 statements related to the definition, classification, diagnostic strategies and treatment of AD. For the diagnosis we suggest the Williams criteria and for severity scoring the SCORAD (by the doctor) and POEM (by the patient). In addition to general care and treatment education (workshops), we suggest four steps for treatment, depending on severity: 1. Topical treatment with anti-inflammatory agents (and systemic: antihistamines/antileukotrienes -low level evidence-) 2. Phototherapy, 3. Cyclosporin A and 4. Dupilumab, with the possibility of managing this biological earlier on if a fast effect is needed. In extrinsic AD we suggest evaluating the addition of allergen immunotherapy or an elimination diet, if there is an IgE-mediated respiratory or food allergy, respectively. CONCLUSION: The panel of experts reached consensus on relevant aspects of AD with a focus on the transcultural adaptation of recent evidence.
Antecedentes: Los abordajes diagnósticos y las estrategias terapéuticas de la dermatitis atópica generalmente son inconsistentes entre los médicos y entre las instituciones de salud. Objetivo: Consensar las opiniones de expertos para reducir las variaciones en la práctica respecto al diagnóstico y tratamiento de pacientes ≥ 12 años con dermatitis atópica para mejorar su cuidado. Métodos: Búsqueda sistemática de la literatura en PubMed y GREAT. Con apoyo metodológico y utilizando el método Delphi se desarrolló un consenso formal entre 16 expertos en dermatología y alergología, basándose en la evidencia actual y su aplicabilidad en el contexto mexicano. A parte de una comunicación electrónica intensa, se discutieron los puntos en desacuerdo en dos reuniones presenciales. Resultados: Los expertos clínicos alcanzaron consenso en 46 declaraciones relacionadas con la definición, clasificación, estrategias de diagnóstico y tratamiento de la dermatitis atópica. Para el diagnóstico sugerimos se usan los criterios de Williams y el SCORAD (por parte del médico) y POEM (por parte del paciente) para definir la gravedad. Aunado a cuidados generales y educación terapéutica, sugerimos cuatro pasos para tratamiento, según gravedad: 1. Manejo tópico con antiinflamatorio (y sistémico: antihistamínico/antileucotrieno evidencia reducida) 2. Fototerapia, 3. Ciclosporina A y 4. Dupilumab, con la posibilidad de manejarlo antes si se necesita efecto rápido. En la dermatitis atópica extrínseca sugerimos agregar inmunoterapia con alérgenos o una dieta de eliminación si existe una alergia IgE-mediada, inhalatoria o alimentaria, respectivamente. Conclusión: El panel de expertos realizó consenso en aspectos relevantes de la dermatitis atópica con enfoque en la adaptación transcultural de evidencia reciente.

INTRODUCCIÓN: La acantosis nigricans es un marcador de resistencia a la insulina, la cual se asocia con alteraciones metabólicas y cardiovasculares. OBJETIVO: Investigar la frecuencia de síndrome metabólico y aterosclerosis carotídea subclínica en niños y adolescentes mexicanos con acantosis nigricans y comparar los resultados entre sexos. MÉTODO: Estudio transversal. Se incluyeron 30 sujetos masculinos y 30 femeninos con diagnóstico de acantosis nigricans, menores de 18 años. Se investigó síndrome metabólico (criterios de Cook), riesgo cardiovascular (proteína C reactiva ultrasensible [PCRus]) y aterosclerosis carotídea (grosor íntima-media). Para el análisis de datos se utilizó estadística descriptiva e inferencial. RESULTADOS: La frecuencia de síndrome metabólico fue de 43 % (sexo masculino 42 % versus femenino 58 %, p = 0.58). Todos presentaron niveles anormales de PCRus: 67 % fue clasificado con riesgo cardiovascular moderado y 27 % con riesgo alto. Frecuencia de aterosclerosis carotídea 98 % (masculino 49 % versus femenino 51 %, p = 0.45). La severidad de la acantosis nigricans no influyó en los resultados. CONCLUSIONES: La búsqueda intencionada de síndrome metabólico y aterosclerosis carotídea subclínica en niños y adolescentes mexicanos con acantosis nigricans, independientemente del sexo o severidad de la enfermedad, permitirá implementar medidas para disminuir la morbimortalidad en la edad adulta. INTRODUCTION: Acanthosis nigricans is a marker of insulin resistance that is associated with metabolic and cardiovascular alterations. OBJECTIVE: To investigate the frequency of metabolic syndrome and subclinical carotid atherosclerosis in children and adolescents with acanthosis nigricans, and to compare the results between genders. METHOD: Cross-sectional study, where 30 male and 30 female subjects younger than 18 years of age diagnosed with acanthosis nigricans were included. The presence of metabolic syndrome (Cook's criteria), cardiovascular risk (ultrasensitive C-reactive protein and [us-CRP]), and carotid atherosclerosis (intima-media thickness [IMT]) was investigated. Descriptive and inferential statistics was used for data analysis. RESULTS: The frequency of metabolic syndrome was 43% (males 42 % versus females 58%, p = 0.58). All patients showed us-CRP abnormal levels: 67% were classified with moderate cardiovascular risk and 27% with high risk. The prevalence of carotid atherosclerosis was 98% (males 49% versus females 51%, p = 0.45). Acanthosis nigricans severity did not influence on the results. CONCLUSIONS: Intentional search for metabolic syndrome and subclinical carotid atherosclerosis in Mexican children and adolescents with acanthosis nigricans, regardless of gender or disease severity, will enable the implementation of measures to decrease the morbidity and mortality seen in adult age.

Protothecosis is a rare infection caused by achlorophyllic algae that are members of the genus Prototheca. They are ubiquitous in nature in organic material. The clinical manifestations can be acute or chronic and local or disseminated. The disease is classified as cutaneous, causing bursitis or disseminated/systemic, affecting both immunocompetent and immunosuppressed patients, with more severe and disseminated infections occurring in immunocompromised individuals. Prototheca wickerhamii and Prototheca zopfii are the most frequent organisms reported in humans. Diagnosis is made by observing asexual sporangia (thecas) on histopathological examination of tissue. Medical and surgical treatment should be considered. Ketoconazole, itraconazole, fluconazole, voriconazole, posaconazole, and amphotericin B are the most commonly used antifungals. Voriconazole and amphotericin B are highly effective against Prototheca spp. Treatment failure is not uncommon because of the comorbidities that limit the therapeutic outcome.

The present work reviews a total lower-eyelid reconstruction technique that is currently not widely in use but which, in some cases, has proven to be of great utility in the field of reconstructive plastic surgery of the palpebral area. We performed an observational, longitudinal, descriptive and retrospective follow-up study. A total of 34 cases of non-melanoma skin cancer in which the lower eyelid was completely reconstructed using one flap taken from the cheek (modified Fricke's cheek flap) were reviewed. The follow-up time for the patients ranged from several months to 5 years. Analysis was performed using the Pearson's chi-square statistical test in an effort to examine the association between the technique's range of functionality and aesthetic variables. Results were considered significant with a p<0.05. The functional result was regular for 91.2%, poor for 8.8% and excellent for 0% (p<0.05). The aesthetic result was regular for 88.2%, poor for 11.8% and excellent for 0% (p<0.05). The main complications were scleral exposure and temporary ocular chemosis. Fricke's lower cheek flap is an easy-to-perform, important and often-necessary technique that, in some cases, has yielded positive functional and aesthetic results. This procedure is performed on an outpatient basis and is optimal for aged patients who present with skin cancer and who require total lower-eyelid reconstruction. The use of this technique is associated with a low complication rate and low morbidity.

Se estudiaron 30 pacientes con enfermedad de Hansen multibacilar (BL o LL) que terminaron el tratamiento controlado según el esquema de la OMS. Se valoraron las baciloscopias de cada paciente en sus índices bacteriológico, morfológico y tintorial durante el inicio, primer año y segundo a lo del tratamiento. Al final del tratamiento 40 por ciento de los pacientes (12) negativizó su índice bacteriológico, el resto de ellos permaneció positivo, por lo que sugerimos que los pacientes con Hansen multibacilar prolonguen por más tiempo el esquema de tratamiento que ha implantado la OMS, para evitar futuras recaídas
