Objective To evaluate the effects of marginal adaptation with different materials on restoring dental wedge-shaped defects. Methods From January 2016 to July 2016,80 patients with 172 wedge -shaped defect teeth in Stomatological Hospital of Haishu District were chosen and randomly divided into three groups accord-ing to random number table method,26 patients with 55 defect teeth were treated with Fuji glass ionomer( group A) , 23 patients with 59 defect teeth were treated with Carey charismatic light-cured composite resin( group B) ,and the other 31 patients with 58 defect teeth were treated with beautifil flow plus reinforced polymer F03(group C). Marginal adaptation of three groups of different materials of the teeth were measured. Results The micro -leakage depth among the three groups had statistically significant difference(H=7. 036,P=0. 035). The micro-leakage depth of group A,B and C were (1. 10 ± 0. 05) mm,(0. 96 ± 0. 05) mm,(0. 78 ± 0. 06) mm,respectively. There was statisti-cally significant difference among the three groups(F=22. 371,P=0. 005). Conclusion The marginal adaptation of beautifil flow plus reinforced polymer F03 is superior to FujiⅡglass-ionome and Charisma composite resin,and has benefits for treatment of wedge-shaped defects.

Objective@#To explore the feasibility of mandibular distraction for the treatment of airway obstruction in neonates with Braddock-Carey syndrome.@*Methods@#From August 2007 to November 2017, 6 neonates with Braddock-Carey syndrome were treated in our center. All patients experienced the combined thrombopoietic treatment before operation. Bilateral oblique mandibular osteotomy was performed by extraoral approaches and the distraction was initiated on postoperative day 3 at a rate of 1.2 mm/d. It usually took around 2 weeks to get required length of distraction. Distractor was removed after 3-months fixation at second stage.@*Results@#The distraction distance of 6 cases was from 12 to 20 mm. The CT scan showed a widening gap of the airway by 6-10 mm, and the average width was around 7 mm. 5 patients had no bleeding and infection after the operation, while one patient experienced bleeding for 4 times treated by regional compression. All neonates felt painful during distraction, and got relieved after reduction of the frequency and pace. With mandibular advancement, all patients′ face type improved, while paroxysmal bruising, inspiratory dyspnea and difficulty in breastfeeding disappeared. After 6 months of follow-up, all patients′ weight and face type were basically the same as normal children.@*Conclusions@#With the treatment of thrombocytopenia before operation, complete hematischesis during the operation, and postoperative treatment of thrombocytopenia, mandibular distraction osteogenesis was a feasible and safe management of upper airway obstruction in neonates with Braddock-Carey syndrome.
Résumé
Resumen La información cuantitativa disponible es escasa para la tortuga carey (Eretmochelys imbricata) en zonas de alimentación en el Pacifico Oriental, donde esta especie representa una de las poblaciones de tortugas marinas más amenazadas del mundo. Entre agosto de 2010 y marzo de 2013 capturamos individuos de tortuga carey utilizando redes de enmalle en los bordes de los manglares y los pastos marinos del Golfo Dulce, Costa Rica. Un total de 62 tortugas carey fueron capturadas, incluyendo 14 recapturas, de las cuales 46 (74.19 %) fueron juveniles (LCC<66cm) y 16 (25.81) fueron adultas. La captura por unidad de esfuerzo (CPUE, 1 unidad: 100m de red por 7h) durante el estudio oscilo entre 0.03 y 0.07. El Golfo Dulces es altamente turbio durante la época lluviosa (mayo-noviembre), particularmente en nuestra área de estudio, debido a la intensa escorrentía que acarrea sedimentos que producen aguas poco cristalinas. La probabilidad de detección de tortugas carey fue considerablemente superior en la época seca (diciembre - abril) comparado con la época lluviosa, lo que sugiere que las tortugas prefieren hábitats con aguas cristalinas. Ninguna de las tortugas capturadas presentaba marcas externas o internas que hicieran concluir que habían sido marcadas en otros sitios de alimentación o reproducción. Un total de 28 (45.16%) individuos fueron hospederos de un ectoparásito (Stephanolepas muricata), el cual puede ser dañino en altas concentraciones al limitar la movilidad de órganos y extremidades. A pesar de que el registro de tortugas carey en agua sigue siendo escaso en el Pacífico Tropical, hasta la fecha este estudio representa el conjunto de datos de monitoreo más largo y robusto para la especie en la región. Nuestros resultados demuestran la relevancia del Golfo Dulce como sitio de alimentación importante para la tortuga carey en el Pacífico Oriental y enfatiza en la necesidad de monitorear y proteger este hábitat, para ayudar a la recuperación de esta población de tortugas marinas que esta críticamente amenazada.
Abstract Limited quantitative information is available for hawksbill turtles (Eretmochelys imbricata) at foraging grounds in the Eastern Tropical Pacific (ETP), where the species composes one of the most endangered marine turtle populations on the planet. Between August 2010 and March 2013 we captured individual hawksbill turtles using entanglement nets along the edges of mangroves and seagrasses of the Golfo Dulce, in southwest Pacific Costa Rica. A total of 62 hawksbills were captured, including 14 recaptures, of which 46 (74.19%) were juveniles (CCL<66cm) and 16 (25.81%) were adults. The catch per unit effort (1 unit: 100m of net for 7h) during the study ranged between 0.03 and 0.07. The Golfo Dulce is highly turbid during the rainy season (May-November), particularly at our study area, as high sediment loads due to intensive runoff lead to poor water clarity. The probability of detection of hawksbills was considerably higher in the dry season (December-April) compared to the rainy season, suggesting these turtles may prefer waters with higher clarity. None of the individuals captured had evidence of internal or external tags, making it possible to conclude that they had not been previously marked at other feeding or breeding sites. A total of 28 (45.16%) individuals were found to host the ectoparasitic barnacle Stephanolepas muricata, which in high concentrations can be harmful by limiting the mobility of organs and limbs. Although consistent in-water quantification of hawksbills in the ETP remains scant, this study represents the longest and most robust marine monitoring dataset for hawksbills in the region to date. Our findings highlight the relevance of the Golfo Dulce as an important foraging ground for hawksbill turtles in the ETP and emphasize the need to monitor and protect this habitat to aid efforts to recover this critically endangered marine turtle population.

OBJECTIVE: To analyze the initial experience of the Division of Urology from HCFMRP-USP on the transperitoneal laparoscopic adrenalectomy. METHODS: We analyze retrospectively 11 cases of laparoscopic adrenalectomy carried out from February of 1,999 to March of 2,003. The sample included all patients operated on through this method in such period and was composed of 3 (27%) men and 8 (73%) women with a mean age of 40,2 ± 13,1 years. The patients had the following diagnosis: adenoma - 5, Cushing's syndrome - 3, feocromocytoma - 1, Conn's syndrome - 1 and Carey's syndrome - 1. RESULTS: The adrenalectomy was bilateral in 5 (45.4%) patients and unilateral in 6 (54.6%) being 4 (36.4%) on the right side and 2 (18.2%) on the left side. The mean hospital stay was 3,6 ± 1,1 days and the mean operating time was 220,5 ± 103,7 minutes. Conversion to open surgery was required in 2 patients (18.2%). CONCLUSION: The results of laparoscopic adrenalectomy were similar to those reported elsewhere and corroborate the safety and efficacy of the method resulting in an acceptable surgical time, faster postoperative recovery and shorter hospital stay.
