RESUMO

The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry.

RESUMO

The purpose of this study is to determine preoperative predictors of the severity of the hypocalcaemia following parathyroidectomy. The case records of 70 patients who underwent parathyroidectomy for primary hyperparathyroidism from 2000 to 2013 was retrospectively studied. Their symptoms at presentation, biochemical parameters serum calcium, parathyroid hormone, alkaline phosphatase and parathyroid size on ultrasound were compared with their serial post-operative serum calcium levels at 24, 48, 72 and 96 h. For the purpose of analysis, patients were divided into three groups. Group 1-asymptomatic, biochemically normal (serum calcium always ≥8.5 mgs%); Group 2-asymptomatic, biochemically below normal (at least one reading <8.5, but none <8.0); Group 3-symptomatic (any one reading <8.0). No correlation was found between the severity of the presenting symptoms, pre-operative serum calcium levels or the parathyroid size with the post-operative calcium levels in the three groups. Though preoperative serum alkaline phosphatase levels were higher in Group 3, it was not statistically significant (p = 0.069). However, preoperative serum parathyroid hormone levels significantly correlated with postoperative serum calcium levels in all three groups (p = 0.006). Pre-operative serum parathyroid hormone levels may serve as a marker for severe post-operative hypocalcaemia and thus identify patients requiring closer monitoring and longer hospitalization following parathyroidectomy.

RESUMO

BACKGROUND: Squamous cell carcinoma of tongue (SCCT) is expected to harbor unique clinico-pathological and molecular genetic features since a significant proportion of patients are young and exhibit no association with tobacco or alcohol. METHODS: We determined P53, epidermal growth factor receptor, microsatellite instability, human papilloma virus infection and loss of heterozygosity status at several tumor suppressor loci in one hundred and twenty one oral SCCT (SSCOT) samples and analyzed their association with clinico-pathological features and patient survival. RESULTS: Our results revealed a significantly higher incidence of p53 nuclear stabilization in early (as against late) onset SCCOT. FHIT loss was significantly associated with p53 nuclear stabilization and the association was stronger in patients with no history of tobacco use. Samples harboring mutation in p53 DNA binding domain or exhibiting p53 nuclear stabilization, were significantly associated with poor survival. CONCLUSION: Our study has therefore identified distinct features in SCCOT tumorigenesis with respect to age and tobacco exposure and revealed possible prognostic utility of p53.

RESUMO

UNLABELLED: Micro vascular free tissue transfer scores over the traditional myocutaneous flaps by providing better cosmesis and function. However, the increased operating tine and costs and the necessity for two operating teams sometimes, negate these advantages and even where this facility is freely available, myoentancous flaps continue to be widely used.To determine the ideal choice of reconstruction in patients after oral resection, we compared our experience with these two methods of reconstruction. Since 1997, when we first started micro vascular reconstruction, 17 patients have undergone this procedure for oral reconstruction. During this same period, 40 patients had pectoralis major myocutaneous flap reconstruction of the oral cavity. These two groups are compared with regard to cosmetic and functional results (as measured by patient's level of satisfaction) operating time, duration of hospitalization, cost and complications. RESULTS: Eightv seven percent of the patients in the micro vascular group and 75% in the myocutaneous group were satisfied with the cosmetic and functional results. In the microvascular group, average operating time was increased by 4 hours; hospitalization by 3 days and average cost of treatment was doubled. Flap failures and re-explorations were significantly higher in the micro vascular group.Based on these results, we would like to suggest the ideal method of reconstruction of the oral cavity in specific subgroups of patients in a corporate hospital setting.
