RESUMO
Pathological scar tissues and normal skin tissues were differentiated by screening for differentially expressed genes in pathologic scar tissues via gene expression microarray. The differentially expressed gene data was analyzed by gene ontology and pathway analyses. There were 5001 up- or down-regulated genes in 2-fold differentially expressed genes, 956 up- or down-regulated genes in 5-fold differentially expressed genes, and 114 up- or down-regulated genes in 20-fold differentially expressed genes. Therefore, significant differences were observed in the gene expression in pathological scar tissues and normal foreskin tissues. The development of pathological scar tissues has been correlated to changes in multiple genes and pathways, which are believed to form a dynamic network connection.

Los abscesos renales son patologías infrecuentes, pero de alta morbi-mortalidad si no son diagnosticados temprano y tratados precozmente. Su vaga e inespecífica sintomatología: dolor abdominal o lumbar, fiebre o mal estado general hacen que su diagnostico sea a veces tardío. La ecografía y/o la TAC dan el diagnóstico en el 100 por ciento de los casos lo que hace posible su tratamiento temprano. El objetivo de este artículo es poner de relieve que el absceso renal es una causa de urgencia urológica a tener presente en pacientes fundamentalmente del sexo femenino, con síntomas de dolor abdominal o fiebre sin clara focalidad urológica.MATERIAL Y MÉTODOS: Se presenta el caso de una adolescente de 16 años con antecedente reciente de forunculosis cutánea supurada en rodilla derecha, que acudió a urgencias por dolor en flanco derecho y fosa iliaca derecha de 10 días de evolución sin fiebre ni síntomas miccionales. Se nos consultó para su valoración, siendo la ecografía el método diagnóstico que se utilizó para la localización de un absceso renal derecho subcapsular de 44 mm en polo superior, y posteriormente para su drenaje percutáneo al no responder porcompleto al tratamiento antibiótico i.v. El cultivo del material purulento del drenaje percutáneo aisló un Staphyloccocus aureus no meticilin resistente. El tratamiento antibiótico i.v asociado a drenaje percutáneo seguido de cloxacilina oral a su alta, curó a la paciente. A raíz de este caso se revisan las series y revisiones sobre abscesos renales de los últimos 10 años, con un total de 179 pacientes, y las publicaciones sobre abscesos renales por Staphyloccocus aureus con tan sólo 13 casos. CONCLUSIONES: Los abscesos renales han de tenerse en cuenta entre las urgencias urológicas. Su diagnóstico y tratamiento percutáneo es mayormente radiológico, reservándose la cirugía abierta o la nefrectomía para abscesos > de 5 cm o pacientes sépticos...
Renal abscesses are infrequent pathologies, but with a high morbidity-mortality if they are not diagnosed and treated early. Its vague and unspecific symptomatology: abdominal or lumbar pain, fever or poor general state, make its diagnosis late sometimes. The ultrasound and/or TAC provide a 100 percent diagnosis of the cases where its early treatment is possible. The objective of this article is to give importance to the fact that renal abscess is a cause of an urological emergency to keep in mind in patients, particularly females with symptoms of abdominal pain or fever without a clear urological focus. MATERIAL AND METHODS: The case of a 16-year-old adolescent is presented with a recent history of festered cutaneous furunculosis on the right knee. She went to the emergency room due to pain on the right side and right illiac fosa with 10 days evolution without fever or urinary symptoms. She came to us for its evaluation, an ultrasound was used for diagnosis to locate a right subcapsular renal abscess of 44 mm on the superior pole, and later for its percutaneous drainage when it did not completely responded to I.V. antibiotic treatment. The culture of the purulent material of the percutaneous drainage isolated a resistant non-methicillin Staphyloccocus aureus. The I.V. antibiotic treatment associated to percutaneous drainage followed by oral cloxacillin upon release cured the patient. CONCLUSIONS: Renal abscesses have to be taken into account among the urological emergencies. Their diagnosis and percutaneous treatment is mainly radiological, leaving open surgery or nephrectomy for abscesses > 5cm or with septic patients...

We report two male adolescents who developed septic thrombosis of the cavernous sinuses after manipulation of a furuncle on the nasal dorsum. We noted in both patients, besides the clinical findings of a generalized infectious process, palpebral edema, proptosis, ptosis, altered pupillary reactivity and bilateral III, IV and VI nerve palsies, as well as dysfunction of the ophthalmic branch of the fifth cranial nerve. One of the patients also had bacterial meningitis. Their cerebral angiograms demonstrated narrowing of the intracavernous portion of both internal carotid arteries. They improved with the antimicrobial treatment, but were left with ptosis and ocular palsies as sequelae. The adequate management of facial furuncle to prevent such a serious complication is emphasized.
