Melgao, Camilo A.;Penna, Letícia M.;Seraidarian, Paulo I.;
Revista Brasileira de Otorrinolaringologia , 2003, DOI: 10.1590/S0034-72992003000300016
Abstract: during temporal bone development and formation it is noted the presence of a foramen in the medial portion of the external auditory canal (foramen of huschke). this foramen is normally present until the age of 4 or 5 years old, but in some people it persists throughout life. the persistence of this foramen and its clinical implications related to the temporomandibular joint, ear and nearby structures has been reported by many authors. therefore, it is important that dentists, otorhinolaryngologists, speech pathologist and physiotherapists have a wide knowledge about the consequences of the presence and persistence of the foramen of huschke.

Revista Brasileira de Otorrinolaringologia , 2003,
Abstract: Durante a forma o e desenvolvimento da por o timpanica do osso temporal, podemos verificar a presen a de um forame na regi o central da parede posterior da fossa articular (parede anterior do meato acústico externo). Este forame (forame de Huschke) está presente em todos os indivíduos, e sua luz oblitera-se por um processo natural de calcifica o ao redor dos 5 anos de vida, podendo persistir, em uma porcentagem da popula o, na idade adulta. A persistência do forame de Huschke foi relatada por diversos autores como sendo possível etiologia de diversas altera es, distúrbios e patologias relacionadas com as articula es temporomandibulares (ATM), ouvidos e estruturas adjacentes. Tendo em vista suas implica es e importancia clínica, torna-se fundamental que profissionais da saúde que atuam nestas regi es reconhe am as conseqüências da presen a e persistência do forame de Huschke.

Melgao, Camilo Aquino;Araújo, M?nica Tirre de Souza;
Dental Press Journal of Orthodontics , 2012, DOI: 10.1590/S2176-94512012000200025
Abstract: introduction: extraction decisions are extremely important in during treatment planning. in addition to the extraction decision orthodontists have to choose what tooth should be extracted for the best solution of the problem and the esthetic/functional benefit of the patient. objective: this article aims at reviewing the literature relating the advantages, disadvantages and clinical implications of asymmetric extractions to orthodontics. methods: keywords were selected in english and portuguese and the endnote 9 program was used for data base search in pubmed, web of science (wsc) and lilacs. the selected articles were case reports, original articles and prospective or retrospective case-control studies concerning asymmetrical extractions of permanent teeth for the treatment of malocclusions. conclusion: according to the literature reviewed asymmetric extractions can make some specific treatment mechanics easier. cases finished with first permanent molars in class ii or iii relationship in one or both sides seem not to cause esthetic or functional problems. however, diagnosis knowledge and mechanics control are essential for treatment success.

Abstract: objective: the purpose of this study is to evaluate the alterations caused by mandibular setback surgery combined or not with maxillary surgery in the upper airways. methods: preoperative and immediate postoperative lateral cephalometric radiographs of 17 class iii patients were evaluated. measurements of the diameter of air space (as) in the sagittal plane were performed in regions corresponding to the hypopharynx and oropharynx; changes in the position of the hyoid bone were also registered. the paired t test and pearson coefficient were used to provide possible associations between skeletal changes and those occurred in the as. results: there was a statistically significant reduction of as in the hypopharynx region (average of 3.10 mm, p = 0.024). the hyoid bone moved backward and downward after the surgery, and the distance between this bone and the anterior region of mandible decreased. it was not possible to correlate, quantitatively, the anteroposterior reduction of the as after the mandibular setback. however, there was a strong correlation between the initial diameter of as and the amount of reduction seen at the hypopharynx; this correlation was found to be moderate at the oropharynx level. conclusions: the mandibular setback surgery can cause significant narrowing of the upper airways, especially in hypopharynx region. therefore, it is important to evaluate this structure during treatment planning of combined orthodontic and surgical cases. possible deleterious effects of these changes on individuals' functions were not yet discarded.

Abstract: The density mean value of raw cow’s milk was studied from 1,049 samples collected in fifty litters brasses from Goiania’s region. The samples were obtained during the morning and evening milkings. That way, one established the mean regional values, which are useful because the implications they show on the nutritional and industrial production and because they contribute to the improvement of the control quality measurements. The found values, using the Thermolactodensimeter, were: morning, l.032±0.001g/ml (1.030 - 1.034); evening, 1.031±0.001g/ml (1.029 - 1.033); mean general value, l.032±0.001g/ml (1.030 - 1.034). The greater frequency of the density values, remained between the limits 1.031 and 1.032/ml performing 71.6% of the total samples. The density showed minor value during the summer and the breed of the animals also affected the mean value of the milk density. The statistics analyses did not reveal any significant statistical difference when it was studied the lactation time effect and the annual variation. O valor médio da densidade do leite cru bovino foi estudado em 1.049 amostras coletadas a partir de lat es de 50 litros provenientes da regi o leiteira de Goiania e obtidas das ordenhas matutinas e vespertinas. Objetivou-se o estabelecimento de valores padr o regionais úteis devido a sua importancia no rendimento industrial e nutricional dos produtos lácteos. Tais valores contribuem ainda para o aperfei oamento das medidas de controle de qualidade no que se refere à interpreta o legal dos padr es previstos na legisla o vigente. Utilizando-se o termolactodensímetro foram encontrados os seguintes valores: matutino, 1,032±0,001g/ml(1,030-1,034) vespertino, l,031±0,001(1,029-1,033); valor médio geral, 1,032±0,001g/ml (1,030-1,034). A maior freqüência dos valores da densidade do leite permaneceu entre os limites 1,031g/ml e 1,032g/ml representando 71,6% do total de amostras. A densidade apresentou valores inferiores no ver o, sendo que a ra a dos animais também afetou o valor médio da densidade. A análise da variancia n o revelou diferen a estatisticamente significante quando se estudou o efeito do tempo de lacta o e a varia o anual.

Abstract: 749 raw milk samples were collected from milk cans at the reception platform of dairy industries, distributed over Goiania and in the interior of the State of Goiás, from April, 1984 to July, 1985. It was found out a prevalence of 7.47% of antimicrobian residues in this food. This value indicates the lack of worry by the Federal Inspection, A. M. , dairy industries, etc., with the quality of this product and with the public health. The comparative results related to the types of federal inspection existing at the dairy industries, approximate distance, in kilometers from farm to the reception platform, milk cans arrival time, dry and rainy periods, showed that the higher frequency of positive samples appeared in the dairies industries with permanent federal inspection, in the farms located 50 km from the dairy industries, and in the milk cans which arrived late to the reception platform. On the other hand, it was found the voluntary addition of antimicrobians in the milk by the conveyor to avoid its acidification. This result may explain a higher positive frequency of cases observed during dry period, instead of rainy period, as expected. No período compreendido entre abril de 1984 a junho de 1985 colheu-se 749 amostras de leite cru de lat es nas “plataformas de recep o” das indústrias laticinistas localizadas na bacia leiteira de Goiania e postos de resfriamento no interior do Estado de Goiás. Naquela oportunidade, encontrou-se uma prevalência de 7,47% de resíduos de antimicrobianos nesse alimento o que evidenciou a inexistência de uma preocupa o maior por parte do Servi o de Inspe o Federal — Ministério da Agricultura, estabelecimentos de leite, assim como, dos produtores com a qualidade do produto e conseqüentemente com a saúde pública, em rela o à presen a desses resíduos. Os resultados comparativos relacionados aos tipos de inspe o federal existentes nos estabelecimentos de leite, distancia aproximada, em km, da propriedade à “plataforma de recep o”, horário de chegada dos lat es à mesma e períodos de seca e chuva mostraram que a maior freqüência de amostras positivas ocorreu nas indústrias de laticínios sob inspe o federal permanente, nas propriedades localizadas a uma distancia de até 50 km da indústria e nos lat es que chegaram tarde à “plataforma de recep o". Por outro lado, constatou-se a adi o voluntária e fraudulenta de antimicrobianos no leite, por parte do transportador, para evitar sua acidifica o. Isto pode ter refletido na maior freqüência de casos positivos observados no período de seca em vez do período de chuva como era esp
