Odontogenic tumors: clinical and pathology study of 238 cases

SummaryOdontogenic tumors are neoplasms that develops exclusively in the gnathic bones; they originate from odontogenic tissues, by epithelial or mesenchymal proliferation, or both.AimTo evaluate the incidence of odontogenic tumors in a specific institution, and to compare these findings with other studies in the literature.Study formatA cross-sectional cohort retrospective study.Material and methodThe sample was obtained from the files of patients with odontogenic tumors diagnosed between January 1992 and March 2007 (15 years). Cases in which the diagnosis could be adapted to the new World Health Organization (WHO) of 2005 were included. Data such as gender, age, anatomical site, histological type and symptomatology were analyzed.ResultsOdontogenic tumors were 4.76% of all biopsied lesions within the studied period. The mean age was 30.7 years; 57% of the patients were male. The keratocystic odontogenic tumor was the most prevalent histological type (30%), followed by the ameloblastoma (23,7%). The rate of asymptomatic cases was 75.7%.ConclusionOdontogenic tumors occurred more frequently in females, in the second and third decades of life, and more commonly in the mandible; most cases were asymptomatic

Impacted foreign bodies in orbital region: review of nine cases

Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. Management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. Metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reaction and lead to serious complications. Despite the modern imaging methods, it is often difficult to identify and locate organic intraorbital foreign bodies. This paper presents a review of nine cases of impacted foreign bodies in the orbital region and discusses the diagnosis and treatment of this kind of injury. The following data were collected: age, gender, etiology of injury, occurrence of fracture, anatomical location of fracture, type of object, signs and symptoms, type of imaging exam used, approach, transoperative complication and occurrence of death. Foreign body injuries in the orbital region can be treated with a combination of clinical suspicion, basic knowledge and diagnostic tests and depend on the skill and experience of the surgeon, thereby decreasing the surgical risk of iatrogenic injury in relation to the inherent risk of retaining an organic intraorbital foreign body

Horizontal Maxillary Osteotomy Approach for Resection of Juvenile Nasopharyngeal Angiofibroma

Juvenile angiofibroma is a benign fibroangiomatous tumor of relatively rare occurrence, developing most frequently in male adolescents. It has local characteristics of aggressiveness and expansion. The treatment of choice is surgical excision. In this article, the advantages and disadvantages of the surgical technique using the Le Fort I osteotomy are described, and the literature correlated with 2 case reports

Stevens-Johnson syndrome associated with antimicrobial agent

Among the severe reactions to medications, immune-mediated Mucocutaneous Disorders are widely represented. Steven-Johnson’s syndrome, or great multiform erythema, appears as a systemic disturbance, involving the skin and mucous membranes, and is related to several factors, such as, viral or bacterial infections and particularly the administration of medicines, in general painkillers and antibiotics. The objective of this article is report the onset of ulcerative vesicle –blister lesions in the regions of the lips, gums, tongue and genital mucosa membrane in a 26 year-old patient, a leukoderm man, being treated with sulfamethoxazole trimethoprim for a respiratory infection, after being diagnosed as having the Steven-Johnson syndrome.

Effectiveness and satisfaction evaluation of patients submitted to TMJ arthrocenthesis: a case series

The aim of this study was to evaluate the effectiveness and level of satisfaction of patients who underwent TMJ arthrocentesis under local anesthesia by considering the following parameters: joint pain, mouth opening, mastication, and satisfaction. Fourteen patients (13 women and one man; mean age, 37.6 years with TMJ arthralgia were selected. The patients underwent arthrocentesis under local anesthesia, and pain intensity was measured before, during, and 1 year after treatment using a visual analog pain scale (VAS 0–100 mm). A Likert scale was used to assess patients’ opinion regarding the improvement of mouth opening and mastication. After treatment, patients were questioned on levels of satisfaction provided by arthrocentesis in regard to their quality of life. At the end of 1 year, patients showed a marked improvement in their pain clinical picture (p < 0.0001). Mouth opening and mastication, evaluated separately and then correlated (R2 = 0.925, p < 0.0001), also showed a marked improvement. When questioned, all patients reported being satisfied with the treatment outcome

Influence of Helmet Use in Facial Trauma and Moderate Traumatic Brain Injury Victims of Motorcycle Accidents

Objective: The objective of this research was to study the influence of the use of helmet in facial trauma victims of motorcycle accidents with moderate traumatic brain injury. Methods: We retrospectively reviewed the incidence of facial injuries in helmeted and nonhelmeted victims with moderate traumatic brain injury at a referral trauma hospital. Results: The sample consisted of 272 patients predominantly men (94.5%) and between 21 and 40 years old (62.9%). The majority of patients were using helmet (80.1%). The occurrence of facial fractures was most frequent for zygomatic bone (51.8%), followed by mandible (18.8%) and nasal bones (9.2%). Conclusions: Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them
