Socio-demographic characteristics are related to the advanced clinical stage of oral cancer.

BACKGROUND: Social determinants may be associated with the onset and progression of the clinical stage of oral cancer. AIM: To evaluate the impact of socio-demographic characteristics on the prevalence of advanced clinical stage of oral cancer. MATERIAL AND METHODS: Information about 51,116 cases of oral cancer, from all Brazilian states, between 2000 and 2012, was obtained from the Cancer Registry Information System. The clinical stage of oral cancer (dependent variable) was classified as initial (stages I and II) or advanced (stages III and IV). The relationship between the clinical stage of oral cancer and the following independent variables was analyzed: sex, age, schooling, marital status, family history of cancer, and origin of referral. Analyses on frequency distribution and multivariate binary logistic regression model were performed (α<0.05). RESULTS: Compared to individuals with no schooling, those who attended elementary to high school (OR=2.461) and college education (OR = 3.050) had a higher prevalence of advanced cases of oral cancer. Individuals without a partner (OR = 14,209) demonstrated a higher prevalence compared to married individuals. Subjects aged 20-44 years (OR = 4.081) and 45-64 years (OR = 14.875) had a higher prevalence compared to those aged 15-19 years. The variables gender, family history of cancer and origin of referral integrated the binary model of logistic regression, but did not present statistical significance. CONCLUSIONS: Socioeconomic factors may be related to the advanced clinical stage of oral cancer.

Síndrome de dirección inadecuada del humor acuoso refractario: una posible complicación de la queratoplastia penetrante / Refractory aqueous misdirection syndrome: A possible complication of penetrating keratoplasty

Caso clínico: Una mujer de 85 años presentó atalamia del ojo izquierdo e hipertensión ocular grave con ecografía normal al día siguiente de la queratoplastia penetrante (QP). Este estado clínico no ha respondido a la terapia médica máxima, con láser y a la vitrectomía 23 G completa. La paciente rechazó otras intervenciones quirúrgicas y la percepción de la luz se perdió después de 6 meses de seguimiento. Discusión: Esta es la primera descripción de síndrome de dirección inadecuada del humor acuoso refractario tras la QP no precedida de trasplante corneal previo. A pesar de los esfuerzos médicos y quirúrgicos máximos, el síndrome de dirección inadecuada del humor acuoso tras QP puede tener una evolución catastrófica (AU)

Clinical case: An 85 year-old woman presented with a flat anterior chamber of the left eye, severe ocular hypertension, and a normal ultrasound examination in the day following a penetrating keratoplasty (PK). The clinical status did not respond to maximum medical therapy, laser posterior capsulotomy, anterior hyaloidotomy, and complete 23 G vitrectomy. The patient refused further intervention, and light perception was lost after 6 months of follow-up. Discussion: This is the first report of refractory aqueous misdirection syndrome following primary PK. Despite maximum medical and surgical management efforts, aqueous misdirection syndrome subsequent to primary PK may have a catastrophic outcome (AU)

Draft genome sequence of Kocuria sp. SM24M-10 isolated from coral mucus

Here, we describe the genomic features of the Actinobacteria Kocuria sp. SM24M-10 isolated from mucus of the Brazilian endemic coral Mussismilia hispida. The sequences are available under accession number LDNX01000000 (http://www.ncbi.nlm.nih.gov/nuccore/LDNX00000000). The genomic analysis revealed interesting information about the adaptation of bacteria to the marine environment (such as genes involved in osmotic and oxidative stress) and to the nutrient-rich environment provided by the coral mucus.
