ABSTRACT

La exóstosis del conducto auditivo externo (ECAE), también conocida como oído de surfista, es una alteración del tejido óseo del oído externo, principalmente causada debido a la sobrexposición al frío. Considerando que los practicantes de deportes acuáticos como el surf y bodyboard de las costas del pacífico sur se exponen a aguas con temperaturas entre 12-16 °C, se busca determinar, en este estudio, la prevalencia y grado de ECAE en practicantes de surf y bodyboard de las localidades de Reñaca y Concón durante el año 2018. Se realizó una evaluación del CAE mediante video-otoscopía a 67 personas (134 oídos) practicantes de surf y bodyboard de las playas de Reñaca y Concón, y se les aplicó un cuestionario respecto a sus hábitos de práctica. Como resultado, se observó una prevalencia de ECAE del 77,6%, siendo el 61,2% ECAE bilateral y el 16,4% ECAE unilateral. Se pudo determinar, además, que el 62,3%de los participantes no usa protecciones. A partir de estos hallazgos, es posible concluir que existe una alta prevalencia de la ECAE en practicantes de surf y bodyboard en las costas centrales chilenas, lo que debería alertar tanto a la población practicante como a profesionales de la salud auditiva con el fin de promover una vida saludable en esta población.


External auditory canal exostosis (ECAE), also known as surfer's ear, is an alteration of the bone tissue of the external ear, mainly caused due to overexposure to cold. Considering that those who practice water sports such as surfing and bodyboarding on the Pacific coast are exposed to waters with temperatures between 12-16 °C,. We seek to determine, in this study, the prevalence and degree of ECAE in surfers and bodyboarders from the coast of the south of Pacific Ocean, Reñaca and Concón, during the year 2018. An evaluation of the ECAE was carried out by means of video-otoscopy in 67 people (134 ears) who practiced surfing and bodyboarding from the beaches of Reñaca and Concón, and a questionnaire was used to collect information about their practice habits. As a result, a prevalence of ECAE of 77.6% was observed, with 61.2% bilateral ECAE and 16.4% unilateral ECAE. It was also possible to determine that 62.3% of the participants do not use protections. Based on these findings, it is possible to conclude that there is a high prevalence of ECAE in surfers and bodyboarders on the central Chilean coasts, which should alert both the practicing population and hearing health professionals to promote a healthy life in this population.

ABSTRACT

SUMMARY: The aim of this study was to survey oral exostoses in human populations that belonged to the same region encompassing five periods over 6000 years, to determine the prevalence and its changing trend over time. A total of 306 human jaws belonging to the modern Xi'an region and four archeological sites, Banpo (6700-5600 years BP), Shaolingyuan (3000 years BP), Shanren (2200 years BP) and Chang'an (1000-1300 years BP), were investigated. The degree of buccal exostosis (BE), torus mandibularis (TM) and torus palatinus (TP) and the TP shape were recorded. The prevalence of BE, TM, and TP in the five groups was 20.8 %-62.5 %, 17.5 %-71.5 %, and 31.7 %-74.2 %, respectively. The differences in the three types of exostoses among the five groups were all statistically significant, but only TM and TP showed a decreasing trend over time. A high and quite diverse prevalence of oral exostoses was found in the five groups of samples. Decreasing trends in relation to time for TM and TP were detected.


RESUMEN: El objetivo de este estudio fue sondear las exostosis orales en poblaciones humanas que pertenecían a la misma región abarcando cinco períodos durante 6000 años, para determinar la prevalencia y su tendencia cambiante a lo largo del tiempo. Un total de 306 mandíbulas humanas pertenecientes a la moderna región de Xi'an y cuatro sitios arqueológicos, Banpo (6700-5600 años AP), Shaolingyuan (3000 años AP), Shanren (2200 años AP) y Chang'an (1000-1300 años AP) BP), fueron investigados. Se registró el grado de exostosis bucal (EO), torus mandibular (TM) y torus palatino (TP) y la forma de TP. La prevalencia de EO, TM y TP en los cinco grupos fue 20,8 % -62,5 %, 17,5 % -71,5 % y 31,7 % -74,2 %, respectivamente. Las diferencias en los tres tipos de exostosis entre los cinco grupos fueron todas estadísticamente significativas, pero solo TM y TP mostraron una tendencia decreciente con el tiempo. Se encontró una prevalencia alta y bastante diversa de exostosis oral en los cinco grupos de muestras. Se detectaron tendencias decrecientes en relación al tiempo para TM y TP.

ABSTRACT

CONCLUSIONS: External ear canal exostosis is more prevalent in northern coastal groups than in the highlands, suggesting that ocean activities facilitate the appearance of exostosis. However, southern coastal groups exposed to colder ocean water have a lesser incidence of exostosis, possibly due to less duration of exposure. There was a high incidence of otitis media in all groups of native population in Chile. One coastal group had a higher incidence, presumably due to racial factors. BACKGROUND: This is a paleopathological and paleoepidemiological study in temporal bones which assesses external ear canal exostosis and otitis media in prehistoric and historic native populations in Chile. MATERIALS AND METHODS: A total of 460 temporal bones were evaluated for exostosis (ex) and 542 temporal bones were evaluated for otitis media (om). The study involved four groups: (1) Prehistoric Coastal (400-1000 AD) populations in Northern Chile (Pisagua-Tiwanaku) (22 temporal bones ex; 28 om); (2) Prehistoric Highland (400-1000 AD) populations in Northern Chile (292 temporal bones ex; 334 om); (3) Pisagua-Regional Developments (coastal) in Northern Chile (1000-1450 AD) (66 temporal bones ex; 82 om); and (4) Historic (1500-1800 AD) coastal populations in Southern Chile (80 temporal bones ex: 18 Chonos, 62 Fuegians. 98 om: 22 Chonos, 76 Fuegians). Skulls were evaluated visually and with an operating microscope. In addition, the otitis media group was evaluated with Temporal bone radiology - -lateral XRays-Schuller view - to assess pneumatization as evidence of previous middle ear disease. RESULTS: Prehistoric northern coastal groups had an incidence of exostosis of 15.91%, the northern highlands group 1.37%, and the southern coastal group 1.25%. There were changes suggestive of otitis media in: Pisagua/Tiwanaku 53.57%; Pisagua/Regional Developments 70.73%; Northern Highlands population 47.90%; Chonos 63.64%; and Fuegian tribes 64.47%.

ABSTRACT

DESIGN: Report of cases. OBJECTIVE: Review of the cases in a period of 10 years with bone and soft tumors in foot and ankle, to knowing epidemilogical, clinic and patologic anatomy parameters to describe the behavior. MATERIALS AND METHODS: Review of 166 cases from 1991 to 2000 and been analyze with descriptive statistic, association measurment for inside stratum, with odds ratio, hipótesis test with chi square for qualitative date and t to Student for quantitative date. RESULTS: 166 patients within 2 years to 78 years old, 81 with bone tumors and 79 with soft tumors, mostly benign, the most frequent was in the soft tissue ganglion and oseal benign exostosis in bone, 6 different malignant tumors, the principal affected zone were the toes, as a difference to literature, the most affected age group was 10 to 20 years followed to the 30 to 40 years old, we report 42 different patological diagnostics results to soft tissue and osseous tissue. CONCLUSION: clinical features is not a useful parameter to differentiate between malign or benign tumors and does not allow to establish the biological behavior, we propose the diagnostic algorithm that includes the intentional clinical probe, comparative X-ray in three projections with soft technique, in suspicion to malignant lesion may require CT scan, MRI, osseous scan and finally biopsy which will improve the final outcome.

ABSTRACT

El estudio es de tipo descriptivo retrospectivo. La muestra fue de 368 historias clínicas que se escogieron aleatoriamente del archivo de la Facultad de Odontología. A cada historia se le diligenció un formato y una vez analizado, se obtuvieron los siguientes resultados: 1. La presencia de torus estuvo en el 61 por ciento de la muestra. 2. Estadísticamente no se encontró diferencia significativa en cuanto al sexo y a la presencia de torus (p>0.05). 3. Fue más frecuente en pacientes de tez morena. 4. En pacientes de la región atlántica 5. Con mayor frecuencia en los pacientes entre los 15 y los 25 años de edad. 6. El torus palatino fue el que más se presentó, ubicándose en tercio medio y posterior. Los torus mandibulares se encontraron en mayor proporción de manera bilateral, ubicándose en zona de premolares y contrario a lo que reporta la literatura en el estudio realizado, no se presentó ningún torus mandibular en zona de molares. Se concluye que la prevalencia de torus palatino fue mayor que la del torus mandibular. El torus se presentó con mayor frecuencia en personas de tez morena y en pacientes entre los 12 y los 25 años de edad. Torus Palatino/ Prevalencia de Torus.

ABSTRACT

AIM: To study the prevalence of tori amongst dental outpatients, the ethnic and sex variations in their distribution, and their clinical features. SETTING: The School of Dentistry, St. Augustine, Trinidad & Tobago. PARTICIPANTS: 667 consecutive dental outpatients representing three different ethnic groups of the country. METHODS: Clinical examination for and recording of tori indicating their location, extent and clinical features and the age, sex and ethnic grouping of the patient. RESULTS: The overall prevalence of tori was 12.3 per cent. CONCLUSIONS: There were no significant differences in the prevalence among the African, Indian or mixed ethnic groups of patients examined. There seemed to be strong link between the coexistence of palatal and mandibular tori.

ABSTRACT

Over one thousand prehistoric crania (n = 1,149) from northern Chile were analyzed to determine if the presence of external auditory exostosis (EAE) was a type of subsistence-induced pathology, a consequence of habitual fishing in the cold water of the Pacific Ocean, rather than genetically determined. To test this occupational hypothesis, the sample was divided according to chronology, type of economy, site elevation, and sex. The crania came from 43 sites, including the coast, lowland valleys (100-2,000 m), and highlands (2,000 to 4,000 m) with a time frame of 7,000 B.C. to the Inca era (1500 A.D.). There was a significant association between EAE, environment, and sex. The coastal inhabitants had the highest prevalence of EAE with 30.7% (103/336), followed by 2.3% (6/24) for the valley people and 0% (0/549) for highlanders. Coastal and valley men were significantly more affected than their female counterparts. Contrary to expectations, there was no significant association between EAE and economy and/or chronology. In the Arica area, the early Chinchorro fishers, without agriculture, had 27.7% (26/94) EAE, the subsequent agro-pastoralists, 42.7% (32/75), and the late Arican agro-pastoral fishers had 35.6% (36/101) EAE. Apparently, with the advent of agriculture, the coastal Arican populations increased their ocean harvests, rather than decreased them, to gain a surplus in order to trade with nonmaritime groups.

ABSTRACT

En el presente estudio se examinó 500 niños de 6 a 17 años de edad; 250 varones y 250 mujeres, de los cuales el 41 por ciento torus palatinus (varones 41.6 por ciento y mujeres 40.4 por ciento), 3.8 por ciento torus mandibularis (varones 4.4 por ciento y mujeres 3.2 por ciento) y 1.8 por ciento ambos torus a la vez (varones 2 por ciento y mujeres 1.6 por ciento); sin encontrar diferencia significativa entre edad y sexo. Fué observado también una mayor frecuencia de torus palatinus fusiformes con 59.5 por ciento, al igual que torus palatinus pequeños con 74.2 por ciento, siendo el 47.8 por ciento de los torus palatinus diagnosticados a la palpación; sin demostrar diferencia significativa con la edad y sexo. Sin embargo pareceexistir una relación entre la morfología del torus y su visualización. Los torus mandibulares con mayor frecuencia observados fueron los simples unilaterales, con 57.9 por ciento, y los clínicamente visibles con 89.5 por ciento. Se encontró además que el lado más afectado fue el izquierdo con 93.3 por ciento. No se pudo demostrar la existencia de una correlación entre la aparición del torus palatinus y del torus mandibularis a la vez.

ABSTRACT

En dos muestras de 261 cráneos (149 masculinos y 112 femeninos) y en 224 cráneos con sus respectivas mandíbulas (114 masculinos y 110 femeninos) del Perú Precolombino, se registró la frecuencia de torus palatinus y torus mandibularis respectivamente. Del primer grupo de cráneos se encontró una frecuencia del 48,7 por ciento de torus palatinus; el 44,9 por ciento de los casos de torus palatinus fueron pequeños; el 48 por ciento y el 52 por ciento representaron las formas plana y fusiforme; y se concluyó que casi no hubo relación con la edad, el sexo y con la altura del paladar, lo cual es contrario al alto porcentaje encontrado en relación con el arco alveolar convergente (50,6 por ciento). Del segundo grupo de cráneos, la frecuencia de torus mandibularis fue del 11,6 por ciento; el 46 por ciento y el 8 por ciento presentaron sólo torus palatinus y sólo torus mandibularis; el 3,6 por ciento presentaron ambas variaciones a la vez, y el 53,8 por ciento de los torus mandibularis fueron simples unilaterales y localizados más en el lado derecho. Por último, no se encontró correlación entre la presencia de ambas variaciones anatómicas

ABSTRACT

The frequency of auditory exostoses was examined by latitude. It was found that discrete bony lesions of the external auditory canal were, with very few exceptions, either absent or in very low frequency (less than 3.0%) in 0-30 degrees N and S latitudes and above 45 degrees N. The highest frequencies of auditory exostoses were found in the middle latitudes (30-45 degrees N and S) among populations who exploit either marine or fresh water resources. Clinical and experimental data are discussed, and these data are found to support strongly the hypothesis that there is a causative relationship between the formation of auditory exostoses and exploitation of resources in cold water, particularly through diving. It is therefore suggested that since auditory exostoses are behavioral rather than genetic in etiology, they should not be included in estimates of population distance based on nonmetric variables.

ABSTRACT

Six hundred and eithty-one dried human skulls of different ethnic backgrounds or localities were examined for the presence of palatal exostosis in the molar region. Of these samples, 276 (40.53%) exhibited some form of palatal exostosis. Chi-square analysis shows that the occurrence of exostosis is: (a) Dependent upon the locality in which the subject lives; (b) Influenced by age; (c) In any age group, dependent upon the locality; (d) Dependent upon the type or class of exostosis; (e) In any type, influenced by locality. The result of this investigation may become clinically important. It suggests, for the clinicians in the field of periodontics, certain diagnostic guidelines for treatment planning of periodontal surgical procedures in the palatal molar region. Thus, an awareness of the patients' ethnic background, as well as age, may be essential in order to minimize or avoid unnecessary postoperative healing complications.

ABSTRACT

The incidence and morphology of torus platinus and mandibularis was verified in 200 Indians, residents of two Brazilian Indian Reserves in São Paulo State, Brazil. A low incidence of both types of exostoses was observed, with torus palatinus occurring more frequently than mandibularis. These structures did not occur in individuals less than 10 years of age. Flattened torus palatinus predominated in relation to the other forms.
