RESUMO

Ductal papillomas are rare benign lesions of the salivary glands with two distinctive types, intraductal and inverted. The rarest anatomical location where intraductal papillomas occur is the major salivary glands. In the present study, we report an intraductal papilloma of the left sublingual gland with the relevant clinical, imaging, and histopathological findings and postoperative follow-up. To our knowledge, this is the fourth case of an intraductal papilloma of a sublingual gland to be reported in the international literature. We present this rare case because of its clinical and radiological imitation of a ranula.

RESUMO

PURPOSE: The aims of this study were to assess the accuracy of the presurgical TNM staging of patients with oral squamous cell carcinoma who underwent neck dissection, to explore the relation between the site of the primary tumor and the histopathologically determined neck metastasis, and to perform survival analysis in relation to the histopathologic neck status. PATIENTS AND METHODS: A retrospective chart review with prospective follow-up of oral squamous cell carcinoma patients who underwent neck dissection was performed. Presurgical clinical neck status (cN) and postsurgical histopathologic neck status (pN) were recorded. Sensitivity, specificity, and likelihood ratios were calculated. Kaplan-Meier survival analysis was performed. RESULTS: The patients clinically staged as cN+ have more than 2-fold odds of having a pN+ neck. Those staged as cN0 have 4 times less odds of a pN+ neck. The mean follow-up was 45.8 months. The median overall survival was 27 months (41 mo in the patients with pN0 and 19.5 mo in the patients with pN+). For the patients with pN0, the 1-year overall survival probability was 95%, falling to 90% at 2 years and 81.8% at 5 years. In the patients with pN+, the 1-year overall survival probability was 72.2%, falling to 44.4% at 2 years and 26.7% at 5 years. Disease-specific and disease-free survival exhibited similar trends. CONCLUSIONS: No means of presurgical assessment either clinical or imaging was sufficiently sensitive and specific enough to predict the metastatic status of the neck. An approximately 50% decrease in the 5-year overall survival rate may be expected when regional metastasis is confirmed.

RESUMO

PURPOSE: To investigate the penetration of cefuroxime into the parotid saliva after short-term intravenous administration in patients undergoing various maxillofacial surgical procedures. PATIENTS AND METHODS: A total of 12 patients, 10 males and 2 females, with a mean age of 41 ± 21.2 years, participated in the present study. Each patient received 1.5 g of intravenous cefuroxime every 8 hours. Blood and parotid saliva samples were collected concomitantly, on the third day of therapy, just before the infusion of the first morning dose, and 0.5 hour after its end. All samples were analyzed using high-performance liquid chromatography. RESULTS: The cefuroxime concentration in plasma and saliva before infusion was 2.08 ± 1.05 mg/L and 0.46 ± 0.33 mg/L, respectively. At 30 minutes after the end of infusion, the corresponding concentrations were 55.54 ± 20.24 mg/L and 14.50 ± 7.85 mg/L. The saliva/plasma ratio was 0.25 ± 0.18 before and 0.26 ± 0.12 after the infusion. CONCLUSIONS: Cefuroxime is excreted in saliva in high levels shortly after infusion but is detected in far lower levels 8 hours after infusion. Taking into consideration the minimum inhibitory concentration values of common pathogens, we have concluded that the saliva concentrations of the drug are sufficient against some, but not all, pathogens involved in the oral-maxillofacial area.

RESUMO

BACKGROUND: Head and neck cutaneous squamous cell carcinoma (HNCSCC) although rarely fatal has significant adverse public health effects due to high medical costs, compromised quality of life, functional impairment and other serious consequences. The present longitudinal cohort study of HNCSCC was designed to determine whether certain clinical-pathologic features of HNCSCC are associated with reduced overall and recurrence-free survival, as suggested by previous data. PATIENTS: The cohort sample consisted of 315 consecutive patients presenting with primary HNCSCC of the head and neck. Life-table analysis and Kaplan-Meier survival analysis were performed. Multivariate Cox's proportional hazards regression models were used to assess the effects of covariates on the length of the interval. RESULTS: There were 145 male and 170 female Caucasian patients. At the time of analysis, 222 patients were alive. The mean follow-up time of a patient after enrolment has been 46.7 months (range, 12-124 months). Broder's differentiation grade, perineural involvement, the presence of inflammation and T-stage were independent adjusted predictors for overall survival. pT and N-stage, inflammation and perineural involvement were significant predictors for recurrence-free survival while adjuvant irradiation was associated with a 92% reduced risk for recurrence. Life-table analysis showed that 87% and 69% study patients were free from recurrence at years 3 and 5, respectively. CONCLUSIONS: Certain clinico-pathological predictors can be used to discriminate subsets of high-risk patients that could benefit from long-term follow-up. After excision in negative margins, patients with HNCSCC should be referred to specialised multidisciplinary oncology clinics for counselling on adjuvant radiotherapy and follow-up.
