RESUMEN

Introduction: Self medication is a component of self care and it is considered as primary public health resource in health care system. It can be defined as use of non-prescription medicines by people on their own initiative. Dentists, together with doctors and veterinarians, comprise the professional classes that may and must prescribe medications for their patients. On the other hand, the nursing professionals are the ones who more administer drugs to patients in the ambulatory and hospital. Objective: This study was aimed to find out the frequency of self medication in selected university students, to find out the difference in the proportions of self medication between dentistry and nursing students, as well to evaluate the students' knowledge of harmful effects of self medication and common problems of students that use the self medication. Material and methods: We were applied 209 questionnaires among dentistry students from the 3rd to 8th semesters at the Paulista University/Goiânia and 542 among nursing students from the 3rd to 8th semesters at the Estacio de Sa University of Goiás. Results and conclusion: In the present study was observed a high rate of self-medication among undergraduate students in the health area, particularly among the dentistry and nurse students. The result was alarming because the professional him/herself who should educate patients and dissuade them from this practice is a habitual user; it makes it more difficult to aspire to the future inhibition and reduction of this practice that is so harmful to health.

RESUMEN

Introduction. Dental treatment performed in patients receiving continuous oral anticoagulant drug therapy is becoming increasingly common in dental offices. For these patients it is imperative to carry out careful anamnesis, as well as a multiprofessional clinical evaluation with regard to the risk and control of hemorrhagic or thromboembolic episodes. Objectives and Material and Methods. The aim is to evaluate postextraction hemorrhagic or thromboembolic episodes in patients who have been on anticoagulant medications for an uninterrupted period of 48 months. Results. Among the 108 patients evaluated, 215 extractions were performed in which there was only one case of postoperative bleeding. Warfarin was used by 98 patients; Warfarin associated with salicylic acetic acid by 9 patients and salicylic acetic acid in only 1 patient. As regards the serologic tests performed, International Normalized Ratio (INR) ranged from 0.8 to 4.9, with a mean of 3.15. Conclusion. Extractions in patients on oral anticoagulants must be performed in the least traumatic manner possible. It is not necessary to stop anticoagulant therapy to perform extractions. Local hemostasis techniques, such as obliterative sutures alone are sufficient to prevent hemorrhagic complications.

RESUMEN

INTRODUCTION: Chronic graft versus host disease (cGVHD) is the most common consequence of allogeneic bone marrow transplantation, and it is associated with morbidity and mortality. Oral manifestations are diagnosed in approximately 80 percent of patients with chronic GVHD. OBJECTIVE: To present a case of chronic GVHD with scleroderma-like lesions in skin and oral cavity CASE REPORT: A 27-year-old female was admitted, in a Hematology Center, in 1997, with previous diagnosis of chronic myeloid leukemia since 1994. Over past four months after allogeneic BTM she developed cGVHD in eyes, mouth, liver, lungs and skin. The patient presented sclerotic skin changes, hyperkeratosis of hands and xerophthalmia. CONCLUSION: Clinical manifestations of chronic GVHD are similar to autoimmune collagen vascular disease and the two main types of cutaneous chronic GVHD are lichenoid and sclerodermatous.

RESUMEN

INTRODUCTION: Epidermoids cysts are benign and rare lesions in oral cavity. It presents as a nodular lesion of sessile base, soft to palpation. In the oral cavity, it most happens on the floor of the mouth's midline. Without treatment, these lesions can lead to dysphagia, dysphonia and dyspnea due to reach a large size. OBJECTIVE: To report a case of a 12-year-old boy presenting a lesion on the tongue's ventral surface causing difficult to swallow. CASE REPORT: The patient was referred to the School of Dentistry of Paulista University, complaining about an asymptomatic nodule on the tongue's ventral surface, lasting for 10 months. Clinical examination showed the extensive fibrous mass on the tongue's medium anterior ventral surface. CONCLUSION: With a clinical diagnosis of dermoid, epidermoid cyst, or lipoma, an excisional biopsy was performed. Histological examination was consistent to the diagnosis of epidermoid cyst. The patient was followed up and 2 years after surgery there was no sign of recurrence.

RESUMEN

The pleomorphic adenoma or mixed benign tumor is the most common benign neoplasia of the salivary gland in human beings. It preferentially occurs in the superficial lobe of the parotid gland. In the oral cavity, associated with the minor salivary glands, it has a greater predilection for the palate region, with slight predisposition in women between the 3rd and 4th decades of life. The radicular cyst is an odontogenic inflammatory cyst resulting from pulp lesions caused by traumas or caries. In spite of being relatively common, there are no reports of association with salivary gland tumors. The aim of this work is to report a case of a 36-year-old woman patient, who presented with synchronous development of a pleomorphic adenoma and periapical cyst within the same region. The option taken was to perform enucleation of both lesions,followed by local curettage. The patient has been followed-up clinically and radiographically for around 18 months without signs of recurrence.

O adenoma pleomórfico ou tumor misto benigno é a neoplasia benigna mais comum primária de glândula salivar. Ocorre preferencialmente no lobo superficial da glândula parótida. Na cavidade oral, associado com as glândulas salivares menores, tem uma maior predileção para a região do palato, com ligeira predisposição em mulheres entre a 3 ª e 4 ª décadas de vida. O cisto radicular é um cisto odontogênico inflamatório decorrente de lesões causadas por traumas ou cárie. Apesar de ser relativamente comum, não há relatos de cistos periapicais associados com tumores de glândula salivar. O objetivo deste artigo é relatar um caso de uma paciente de 36 anos de idade com desenvolvimento sincrônico de adenoma pleomorfo e cisto periapical em uma mesma região. A opção tomada foi a de realizar a enucleação de ambas as lesões, seguido de curetagem local. A paciente está sendo acompanhada clínica e radiograficamente por cerca de 18 meses sem sinais de recidiva.

RESUMEN

The calcifying cystic odontogenic tumor (CCOT) is a rare odontogenic lesion derived from the remaining odontogenic epithelium of the maxilla or mandible. Its occurrence in the maxilla and mandible is similar, however, the canine region is the most affected when compared with other regions. The aim of this paper is to relate the case of a patient who presented a CCOT in the left region of the maxilla, between the canine and the first premolar, characterized by an increase in volume that was painful on palpation. The lesion presented a well circumscribed radiolucent radiographic image, however, presented no root resorption and radiopacities suggestive of dystrophic calcification, common signs in this tumor. With the diagnostic hypothesis of a lateral periodontal cyst, enucleation of the lesion was performed. The patient has been followed-up for around 15 months without signs of recurrence.

O tumor odontogênico císto calcificante (TOCC) é uma lesão odontogênica rara derivada do epitélio odontogênico remanescente da maxila ou mandíbula. Possui ocorrência semelhante em maxila e mandíbula, porém a região de canino é a mais afetada quando comparada com outras regiões. O objetivo deste estudo é relatar um caso de um paciente que apresenta um TOCC em região esquerda de maxila, entre o canino e o primeiro pré-molar, caracterizado com aumento de volume doloroso à palpação. Radiograficamente a lesão apresentava imagemradiográfica radiolúcida bem circunscrita, no entanto não apresentava reabsorção radicular e radiopacidades sugestivas de calcificação distrófica, sinais comuns neste tumor. Com hipótese diagnóstica de cisto periodontal lateral, foi feita enucleação da lesão. O paciente está em acompanhamento há cerca de 15 meses sem sinais de recorrência.

RESUMEN

Cleidocranial dysplasia is a developmental anomaly of the skeleton and teeth. It can be inherited as an autosomal dominant characteristic with high penetrance and variable expressivity. It occurs with equal frequency in both genders and races. The clinical appearance of cleidocranial dysplasia is pathognomonic. The stature is mildly to moderately shortened, with neck appearing long and narrow and the shoulders markedly drooped. Maxillary hypoplasia gives the mandible a relatively prognathic appearance, although some patients may show variable mandibular prognathism due to increased length of the mandible in conjunction with short cranial base. The head and neck features are very variable. Herein, we are described one cleidocranial dysplasia case, in an 84 year female patient, with the dentigerous cyst, which she were not kwon the diagnosis of the her congenital syndrome.

A displasia cleidocraniana é uma alteração de desenvolvimento do esqueleto e dos dentes. É uma desordem autossômica dominante com alta penetrância e expressibilidade variada. Ocorre em igual frequência em ambos os gêneros e raças. Suas características clínicas são patognomônicas. Apresenta estatura baixa a moderada, com aparência do pescoço longo e os ombros caídos. Hipoplasia da maxila gera um aparente prognatismo. As características clinicas em cabeça e pescoço são muito variadas. Este relato descreve um caso de uma paciente de 84 anos com displasia cleidocraniana associada a cisto dentígero a qual não sabia ser portadora de tal síndrome congênita.

RESUMEN

Objetivo - A Doença do Enxerto contra o Hospedeiro crônica (DECHc) é uma das mais frequentes complicações tardias do transplante de medula óssea alogênico. A cavidade bucal é o local de maior acometimento desta patologia. Métodos - Este estudo visa investigar a incidência de DECHc, os locais de acometimento, assim como o tipo de lesão em cavidade bucal. Foram avaliados, retrospectivamente, através de prontuários médicos, 98 pacientes que foram submetidos a transplante de medula óssea alogênico no Hemocentro/Unicamp, em um período de um ano. Foram analisadas a presença ou ausência da DECH crônica, os sítios de maior acometimento das lesões e, quando em cavidade bucal, os locais e aspecto clínico mais importantes. Resultados e Conclusões - Dos 98 pacientes, 64 apresentavam DECHc. Destes, 51 apresentavam envolvimento bucal. Em boca, 27 foram em mucosa bucal e a forma clinica mais frequente foi a liquenóide. Nenhum fator encontrado pode contribuir com a severidade da DECHc em cavidade bucal assim como suas manifestações clínicas.

Objective - Chronic graft versus host disease (cGVHD) is the most common late complication of allogeneic bone marrow transplantation. Oral cavity is the most common site of involvement of cGVHD. Methods - This study sought to investigate the incidence of cGVHD, the site of involvement, as well as the kind of oral lesions that resulted. They had been evaluated through medical handbooks, 98 patients who had been submitted the blood marrow alogenic transplant in the Hemocentro/Unicamp, in a period of one year. The presence or absence of the chronic GVHD had been analyzed, the side of the body injuries and, when in oral cavity, the more important places and clinical aspect. Results and Conclusions - Of ninety eight patients, sixty four were cGVHD. Fifty one patients presented oral involvement. On the oral cavity, twenty seven were on buccal mucosa and the clinic features most prevalent was the lichenoid type. No factor that could contribute to the severity of cGVHD oral lesions was found.

RESUMEN

Telangectasia Hemorrágica Hereditária, também conhecida como síndrome de Rendu-Osler-Weber, é uma alteração caracterizada por uma displasia fibrovascular associada com a presença de telangectasias e malformações arteriovenosas. Acomete preferencialmente a pele, mucosas, pulmão e cérebro. No passado, era considerada uma doença rara, sem grandes conseqüências na vida dos indivíduos afetados. Entretanto, nos dias atuais, é reconhecida como uma entidade não tão incomum, e quando envolve o cérebro e os pulmões, está associada a altas taxas de mortalidade e morbidade destes pacientes. O objetivo deste estudo foi relatar um caso de telangectasia hemorrágica hereditária no qual a suspeita do diagnóstico foi feita pela detecção de telangectasias intrabucais

RESUMEN

BACKGROUND: Human herpesvirus 6 (HHV6) is the etiologic agent of exanthem subitum. The virus is latent in salivary glands and saliva is the main form of viral transmission. The objective of this study was to assess HHV6 incidence in the fluids from healthy individuals using a standardised technique for collecting and extracting viral DNA from gingival crevicular fluid, whole saliva and parotid gland saliva. DESIGN: Samples of oral fluids and peripheral blood were collected from 28 blood donors and HHV6 was detected using PCR assay. Parotid gland saliva and gingival crevicular fluid were collected by endodontic paper cones in order to not contaminate these fluids with whole saliva. RESULTS: Of the 28 donors, 20 (71.4%) presented positive results in at least one of the three oral fluids researched. Whole saliva was positive in 19 (67.8%) volunteers, while only four (14.2%) samples of gingival crevicular fluid and four of parotid gland saliva proved to be positive. CONCLUSIONS: The results suggest that HHV6 is present in the saliva of a large proportion of the healthy adult population. The use of endodontic paper cones for oral fluid collection and viral extraction was efficient, simple, cheap and painless. In spite of, the small number of cases studied it was possible to demonstrate that neither gingival crevicular fluid nor parotid gland saliva were the principal source of HHV6 in whole saliva.
