An unusual case of nasopalatine cyst in Brazilian population / Um caso incomum de cisto nasopalatino na população brasileira

The nasopalatine duct cyst (NPDC) is the most common non-odontogenic cyst typically found in middle-aged Caucasian female in Brazil, however the present report describes a case in a 35 year-old black male. NPDC are usually asymptomatic and are discovered incidentally during routine radiological examination. A cone-beam computed tomography (CBCT) is a valuable tool to localize a cyst within the nasopalatine canal. CBCT enables analysis of the dimension of the NPDC, analysis of the involvement of neighboring anatomical structures and assists in treatment planning. The authors at this case highlight the importance of clinical examination with an unbiased view of age, gender and ethnicity.

O cisto do ducto nasopalatino (CDNP) é o mais comum dos cistos não-odontogênicos geralmente encontrado em mulheres brancas de meia idade no Brasil, embora o presente relato descreva um caso em um homem negro de 35 anos de idade. Os CDNP são usualmente assintomáticos e são descobertos acidentalmente durante o exame radiográfico de rotina. A tomografia computadorizada por feixe cônico(TCFC) é uma ferramenta válida para localizar o cisto dentro do canal nasopalatino. A TCFC permite análise da dimensão do CDNP, análise do envolvimento das estruturas anatômicas vizinhas e auxilia no planejamento do tratamento. Os autores neste caso alertam para a importância do exame clinico, com uma visão embasada na idade, gênero e grupo étnico.

Ear nose and throat diseases in the Bedouin of the South Sinai Desert: a cross-sectional survey and discussion of healthcare needs.

In the summer of 2000, a team of medical and affiliated workers visited the South Sinai Desert to assess the medical problems and needs of the Bedouin population. This paper reports on the ENT diseases of this population, and discusses their healthcare needs.

Evaluation of nasal cavity by acoustic rhinometry in Chinese, Malay and Indian ethnic groups.

Acoustic rhinometry (AR) evaluates the geometry of the nasal cavity by measuring the minimum cross-sectional area (MCA) and nasal volume (V) by means of acoustic reflection. Understanding the normal and pathologic conditions of the internal nasal cavity using AR is important in the diagnosis of structural abnormalities in patients. The aim of this study was to investigate the normal range of AR parameters in healthy volunteers from three ethnic groups in Singapore: Chinese, Malay and Indian. We also attempted to evaluate the role of these measurements in the documentation of structural abnormalities in the nose. A total of 189 Singaporeans, aged > or = 18 years, were recruited from a nationwide survey study. They comprised 83 Chinese, 35 Malays and 71 Indians. Eighty-nine subjects had a rhinoscopically normal nose (Group 1), 77 had significant septal deviation (Group 2) and 23 had inferior turbinate hypertrophy (Group 3). AR was performed to measure the MCA at the anterior 1-5 cm from the nostril and the volume (V) between points at the nostril and 5 cm into the nose. A mean MCA (mMCA; equal to (L + R)/2) and a total volume (Vt; equal to L + R) were then calculated for each subject, where L and R refer to the measurements made for the left and right nostrils, respectively. The results showed that there was no statistically significant difference in mMCA (p = 0.80) and Vt (p = 0.60) among the three ethnic subgroups of Group 1. Statistically significant differences were found only between Groups 1 and 3 (p < 0.001 for both mMCA and Vt) and between Groups 2 and 3 (p = 0.001 for mMCA and p = 0.013 for Vt). Although there was no significant difference between Groups 1 and 2, significant differences in MCA (p = 0.001) and V (p = 0.040) were found between the narrower sides (smaller volume) and the wider sides in Group 2, indicating volume compensation between the nasal cavities. In conclusion, our study demonstrates that there is no significant difference in the normal range of AR measurements among Chinese, Malay and Indian ethnic groups. AR is able to determine the structural abnormality of the internal nasal cavity caused by septal deviation and inferior turbinate hypertrophy.
