Jael syndrome: removal of a knife blade impacted in the maxillofacial region under local anaesthesia.

The presence of retained foreign bodies in the maxillofacial region as a consequence of penetrating injuries from knives is poorly documented in the scientific literature. This manuscript reports the case of a 30-year-old Caucasian with a knife blade lodged in the maxillofacial skeleton. Following clinical and radiographic exams, it was determined that the object had penetrated through the left nostril and nasal septum, in the direction of the right maxillary sinus, and remained impacted without causing injury to important anatomical structures.

Report of a case of solitary fibrous tumour of the orbit.

Background: Solitary fibrous tumors of the orbit are uncommon lesions, only one relatively large series having been published. Neoplasms, formerly considered as separate entities, including hemangiopericytoma, are presently encompassed as solitary fibrous tumors, a unifying designation. There is a tendency towards recurrence and some cases are malignant.

Epidemiologic profile and quality of life of patients treated for oral cancer in Juiz de Fora, Minas Gerais, Brazil.

Objectives: To assess the quality of life of patients treated for oral cancer, analyzing their physical, social/family, functional and emotional well-being; to identify socioeconomic and clinical functional variables that may potentially influence their quality of life; to describe the patients' epidemiologic profile (sex and age) and tumor features (histopathology, anatomical location and stage); to identify the frequency of risk factors associated with the malignancy.

Study Design: Observational cross-sectional study-case series study undertaken in 2 cancer treatment institutions in Juiz de Fora, Minas Gerais, Brazil, between 2000 and 2007.

Results: Of the 88 registered oral cancer patients, 16 were selected for the study sample.

Juvenile ossifying fibroma of the jaw.

Juvenile ossifying fibroma is a benign lesion with aggressive local growth. It is similar to an ossifying fibroma, although it is more aggressive and of earlier onset. Some cases of ossifying fibroma are part of a syndrome that includes hyperparathyroidism (caused by adenoma or carcinoma) and renal lesions, possibly caused by a recently discovered genetic mutation.

Effectiveness of nasopalatine nerve block for anesthesia of maxillary central incisors after failure of the anterior superior alveolar nerve block technique.

The purpose of this study was to assess the effectiveness of nasopalatine nerve block for anesthesia of maxillary central incisors after failure of the anterior superior alveolar nerve (ASAN) block technique. Secondarily, the possible innervation of the maxillary central incisors by the nasopalatine nerve was also investigated. Twenty-seven healthy, young adult volunteers (age: 17-26 years; gender: 9 males and 18 females) were enrolled in this study.

Ketamine reduces mortality of severely burnt rats, when compared to midazolam plus fentanyl.

Ketamine can provide protective effects, through its anti-inflammatory properties, as shown in animal models of septic shock and endotoxemia, and has elicited the heat-shock response (HSR) in experimental studies. The HSR has reduced the mortality after severe burns in rats. This study has tested the hypothesis that ketamine could be protective in experimental burns and that it could generate the HSR.
