ABSTRACT
OBJECTIVE: To determine the most frequent dermatoses in patients with kidney transplant in the dermatology consultation, Hospital de Especialidades, Centro Médico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, in Mexico City, in the period from March 2016 to March 2020. METHOD: Descriptive, cross-sectional study that included 153 patients with a complete medical history with prior informed consent and authorization from the hospital ethics committee. RESULTS: All patients presented one or more dermatoses. The most frequent were infectious (mycosis, viral) and, in decreasing order, other dermatoses (keratosis pilaris, melasma), tumorous (benign), inflammatory (seborrheic dermatitis, eczema), probably secondary to drugs and autoimmune (alopecia areata). CONCLUSIONS: All kidney transplant patients presented at least one dermatosis, predominantly those of infectious origin. We recommend dermatological evaluation prior to transplantation for timely diagnosis and treatment of dermatoses that could increase the morbi-mortality of patients.
OBJETIVO: Determinar las dermatosis más frecuentes en pacientes con trasplante renal en la consulta de dermatología del Hospital de Especialidades, Centro Médico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, en Ciudad de México, en el período de marzo de 2016 a marzo de 2020. MÉTODO: Estudio descriptivo, transversal que incluyó 153 pacientes con historia clínica completa, previo consentimiento informado y autorización del comité de ética del hospital. RESULTADOS: Todos los pacientes presentaron una o más dermatosis. Las más frecuentes fueron las infecciosas (micosis, virales) y, en orden decreciente, otras dermatosis (queratosis pilar, melasma), tumorales (benignas), inflamatorias (dermatitis seborreica, eccemas), probablemente secundarias a fármacos y autoinmunitarias (alopecia areata). CONCLUSIONES: Todos los pacientes receptores de trasplante renal presentaron al menos una dermatosis, predominando las de origen infeccioso. Recomendamos una valoración dermatológica previa al trasplante para el diagnóstico y el tratamiento oportuno de las dermatosis que podrían aumentar la morbimortalidad de los pacientes.

New desulfurizing bacteria able to convert dibenzothiophene into 2-hydroxybiphenyl and sulfate were isolated from contaminated soils collected in Mexican refineries. Random amplified polymorphic DNA analysis showed they were different from previously reported Rhodococcus erythropolis desulfurizing strains. According to 16S rRNA gene sequencing and fatty acid analyses, these new isolates belonged to the genus Rhodococcus. These strains could desulfurize 4,6-dimethyldibenzothiophene which is one of the most difficult dibenzothiophene derivatives to remove by hydrodesulfurization. A deeply hydrodesulfurized diesel oil containing significant amounts of 4,6-dimethyldibenzothiophene was treated with Rhodococcus sp. IMP-S02 cells. Up to 60% of the total sulfur was removed and all the 4,6-dimethyldibenzothiophene disappeared as a result of this treatment.
