1. Analysis of radiopacity, pH and cytotoxicity of a new bioceramic material
AbstractObjective RetroMTA® is a new hydraulic bioceramic indicated for pulp capping, perforations or root resorption repair, apexification and apical surgery. The aim of this study was to compare the radiopacity, pH variation and cytotoxicity of this material to ProRoot® MTA.Material and Methods Mixed cements were exposed to a digital x-ray along with an

2. Tympanomastoidectomy: comparison between canal wall-down and canal wall-up techniques in surgery for chronic otitis media
INTRODUCTION: Chronic otitis media (COM) is an inflammatory condition associated with otorrhea as well as large and persistent perforations of the tympanic membrane in some cases. COM can also lead to cholesteatoma. Surgical treatment with canal wall-down and canal wall-up tympanomastoidectomy is considered for both types of illness. The choice of technique

3. Estudo imunoistoquímico, tomográfico e histológico sobre a remodelação de enxertos ósseos onlay. Parte II (Calota Craniana) / Immunoshistochemical, tomographic and histological study on onlay bone grafts remodeling. Part II - Calvarial bone
Several studies have discussed factors that govern the longevity of onlay bone grafts. However, little information has been made available on molecular events that occur over time. Cranial bone grafts have been reported to produce greater responses compared to other donor regions in maxillofacial reconstructions, but necessary scientific verification was sti

4. Estudo do buraco macular fechado cirurgicamente: avaliação da relação entre a integridade da camada de fotorreceptores e a acuidade visual final por meio da tomografia de coerência óptica / Optical coherence tomography evaluation of surgically closed macular holes: photoreceptor layer integrity analysis and its correlation with final visual outcome
Introdução: O tratamento do buraco macular idiopático ainda é acompanhado de incertezas em relação ao seu prognóstico. Ao longo dos últimos anos, têm sido utilizados o tempo de história, o tamanho e a acuidade visual pré-operatória dos buracos como critérios de orientação quanto ao resultado visual final. O aspecto final da parte mais externa

5. Tratamento transureteroscópico do cálculo ureteral com HOLMIUM: YAG laser / Transureteroscopic treatment of ureteral stones with the Holmium:YAG laser
Objetive: Holmium:YAG laser is the more recently method of intracorporeal lithotripsy of urinary calculi introduced in our area. The purpose of this study is to analyze the technique and to evaluate the immediate results and complications in the treatment of patients with ureteral calculi. Casuistry and Methods: Sixteen patients were treated, nine men and se

6. Mechanisms of gastric and esophageal perforations during laparoscopic Nissen fundoplication.
OBJECTIVE: The purpose of this study was to determine possible mechanisms of 17 gastric and esophageal perforations that occurred during laparoscopic Nissen fundoplication. METHODS: Specific details of each perforation relating to mechanism of injury, surgeon experience, diagnosis, treatment, and outcome were obtained. For each perforation, an attempt was ma

7. Instrumental perforations of the oesophagus and their management.
The records of 39 patients who had developed a perforation of the oesophagus after instrumentation were reviewed. Ten (group A) had cervical and 29 (group B) thoracic oesophageal perforation. Twenty three perforations occurred during dilatation of an oesophageal stricture, 10 during oesophagoscopic removal of a foreign body, and six during diagnostic oesopha

8. Emergency operations for gastric and duodenal ulcers in high risk patients.
With routine endoscopy, histamine antagonists, proximal gastric vagotomy (PGV) and declining prevalence of duodenal ulcers, morbidity and mortality of ulcer surgery should have declined. Two hundred thirty-four ulcer operations performed since 1976 were compared with 778 between 1961 and 1971. The hospital mortality rate has increased from 2.7 to 14.5%. Incr

9. Highly selective vagotomy in duodenal ulceration and its complications. A 12-year review.
Highly selective vagotomy (HSV) was performed in 509 patients over 12 years for the surgical management of duodenal ulceration; 103 HSVs were carried out during the treatment of complications. The overall rate of ulcer recurrence was 7%, ranging from 10% in the first 4 years to 4% in the 6 years between 1975 and 1980. Highly selective vagotomy was performed
