RESUMO
Salivary gland tumors generate considerable interest because of their heterogeneous and variable histology, grade of malignancy, and clinical behavior. Fine needle aspiration cytology (FNAC) is considered the first diagnostic modality for salivary neoplasms due to its ready availability and ease of performance. However it cannot always be relied upon in isolation, and should be used in conjunction with other investigations like incisional biopsy. We present two cases, which highlight the drawbacks of relying on FNAC alone, which resulted in misdiagnosis of adenoid cystic carcinoma as pleomorphic adenoma.
RESUMO
Cemento-ossifying fibroma (COF) is a benign fibro osseous lesion of the jaws which has been described as a demarcated or rarely encapsulated neoplasm consisting of fibrous tissue and varying amounts of mineralized material resembling bone and/or cementum (Dinkar et al. in IJDA 2(4):45-47, 2010). Majority of lesions occur in the mandible and only few cases of COFs of the maxillary sinus and bilateral COFs of the mandible have been reported in literature (Dinkar et al. in IJDA 2(4):45-47, 2010; Tamiolakis et al. in Acta Stomatol Croat 39(3):319-321, 2005; Hamner et al. in Oral Surg Oral Med Oral Pathol 26(4):579-587, 1968; Gunaseelan et al. in Oral Med Oral Pathol Oral Radiol Endod 104:e21-e25, 2007). These lesions have a very low recurrence rate (Ertug et al. in Quintessence Int 35(10):808-810, 2004) and are generally treated by enucleation. In this paper we present a rare case of COF occurring in both the maxilla and mandible of the same patient. Only one such case (Takeda and Fujioka in Int J Oral Maxillofac Surg 16(3):368-371, 1987) has been reported in literature so far.
RESUMO
OBJECTIVES: To retrospectively analyze all patients who were diagnosed with Osteomyelitis of jaws in our unit. STUDY DESIGN: 31 patients with Osteomyelitis of jaws were analyzed retrospectively from 2002 to 2008 at the Department of Oral & Maxillofacial Surgery, S.D.M College of dental sciences and hospital, Dharwad, India. Parameters considered were age, gender, jaws involved, clinical features, surgical management & complications. RESULTS: Of the 31 patients, maxilla was involved in 16 patients and mandible was involved in the remaining 15. 11 out of the 16 patients with maxillary osteomyelitis were immuno-compromised. The predominant etiology noted was odontogenic infection. With the treatment protocol we have adopted, all our patients showed satisfactory resolution of the condition by 6 weeks. CONCLUSION: Incidence of maxillary osteomyelitis & their association with diabetes mellitus was higher in our series compared to others. The cause for this high incidence was analyzed in our study. Based on our results we conclude that a conservative surgical method with an attempt to preserve vital bone and an appropriate antibiotic therapy with the correction of the underlying medical problems is adequate to treat Osteomyelitis of jaws.
RESUMO
BACKGROUND: Lignocaine hydrochloride is the most widely used and easily available local anaesthetic agent. Adrenaline is frequently combined with lignocaine to enhance the duration of anaesthesia, decrease toxicity, to achieve vasoconstriction and to provide a bloodless field. AIM AND OBJECTIVE: This study was conducted to do the comparative evaluation of local anaesthesia with adrenaline and without adrenaline on blood glucose concentration in patients under going tooth extraction. MATERIALS AND METHOD: The study was conducted on 120 patients comprising of 60 healthy and 60 diabetic patients. All these patients were in need of multiple extractions. The patients were in the age group of 18-50 years. On their first visit the patients were given plain lignocaine and tooth extraction was carried out. One week later the same patient was given lignocaine with 1:80,000 adrenaline to carry out tooth extraction. Serial blood glucose estimations were done at definite intervals (prior to administration of local anaesthetic, immediately after injecting the LA, 10 and 20 min following the injection of LA) on both the occasions. RESULTS: The mean blood glucose concentration increased from the base line level of 84.81 to 85.09 mg/dl in healthy patients and from 206.82 to 207.09 mg/dl in diabetic patients 10 min following the injection of 2% plain lignocaine. This increase in blood glucose concentration following the administration of plain lignocaine was statistically not significant (P > 0.05). There was statistically significant (P < 0.005) increase in the blood glucose concentration from 88.81 to 105.55 mg/dl in healthy, and 208.77 to 242.46 mg/dl in diabetic patients 20 min following the injection of lignocaine with adrenaline. INTERPRETATION AND CONCLUSION: While assessing the generalized effects of local anaesthetic solutions, metabolic as well as haemodynamic responses should be investigated. Adrenaline containing LA should be used with caution in Type 2 diabetics as adrenaline causes suppression of insulin release.
