The aim of this paper is to describe the case of a 53-year-old female patient, with renal failure who has been on dialysis for 6 years and developed severe secondary hyperparathyroidism and brown tumor of the maxilla and mandible, confirmed by incisional biopsy. Parathyroidectomy was indicated as a result of rapid growth of the tumor and the maintenance of laboratory findings. Despite the normalization of serum parathyroid hormone and alkaline phosphatase, tumor regression was slow and patient's important functional and esthetic deficits persisted. Excision of the mandible tumor was conservative. Osteoplasty was recommended because during a 5-year follow-up there was regression of the lesion, decreased pain, bleeding, and tooth mobility.
Injuries in the parotid and masseter region can cause serious impairment secondary to damage of important anatomical structures. Sialocele is observed as facial swelling associated with parotid duct rupture due to trauma. The aim of this paper is to report a case of a giant traumatic sialocele in the parotid gland, secondary to a knife lesion in a 40-year-old woman. Conservative measures could not promote clinical resolution and a surgical intervention for the placement of a vacuum drain was selected. Under local anesthesia, a small incision was performed adjacent to parotid duct papilla, followed by muscular divulsion and draining of significant amount of saliva. An active vacuum suction drain was placed for 15 days, aiming to form a new salivary duct. This technique was shown to be a safe, effective and low-cost option, leading to complete resolution and no recurrence after 28 months of follow up.
Snake bite envenomation has considerable medical importance because of its frequency and severity. An updated standardization of diagnosis and treatment conduct is essential. At no time did the patient develop respiratory insufficiency, neurotoxicity, or renal failure. Tongue damage rapidly resolved after early and aggressive treatment. The preserved tongue remained well perfused and viable, and tongue mobility was good. The aim of the present study was to describe a rare case of snake bite envenomation in the tongue, emphasizing risk factors, the patient's clinical evolution, and the importance of early, multidisciplinary treatment.
<span class="texto">A Displasia Cemento Óssea Florida (DCOF) é uma lesão controvertida em relação ao seu diagnostico, pelos seus aspectos clínicos e radiográficos muito semelhantes a outras lesões ósseas esclerosantes. Acomete principalmente a mandíbula de mulheres negras com idade acima de quarenta anos. Apresenta um aspecto radiográfico de massas densamente radiopacas, entremeadas por faixas radiolúcidas, sem limite definido. Pode desenvolver expansão óssea alveolar, supuração e fistulação, caso esteja associada à infecção secundaria (osteomielite), que ocorre devido à exposição da massa óssea avascular à cavidade bucal.</span>
