    Abstract The shortage of organ availability in recent years has made it necessary to use grafts from advanced-aged donors to maintain the rate of renal transplantation in our country. The objective of this study was to evaluate the graft function and patient survival using kidneys from deceased donors of over 65 year of age. From 2005 until 2010, we compared the outcomes of patients who received grafts from donors over 65 years old vs less than 65 years. We observed no significant difference in sex, time on dialysis, or cold ischemia time between the groups. As expected the recipient age was significantly different. For the analysis of survival, we used the Tablecloth-Haenzel test and the Kaplan-Meier survival estimator. Actuarial survivals at 3 years after transplantation showed 84.8% among patients transplanted with kidneys from donors over 65 years old versus 97.5% in the control group. The graft survival was 78.8% among expanded criteria versus 86.85% in the control group. When we analyzed graft survival using an "exitus-censured" analysis, we obtained graft survivals of 89.1% in the expanded criteria kidney group versus 88.6% among the controls. We concluded that the use of kidney from donors over 65 years of age allows us to increase the rate of renal transplantation to about 15 to 20 per million population, with good graft and patient survivals provided that the protocol for expanded criteria organs ensured proper macroscopic and microscopic evaluation of the organ for transplantation.

    Title translation A bronchogenic cervical cyst. A case report.
    Abstract The bronchogenic cyst is a tracheobronchial tree congenital malformation, normally intrathoracic. Usually presenting as an acute respiratory insufficiency (especially during infancy) or as recurrent respiratory infections or may be an accidental finding in asymptomatic patients. We present a rare case of cervical localization which began as an acute respiratory distress following a tonsilar infection.

    Title translation Aspergillosis of maxillary sinus: a case report.
    Abstract A case of semi-invasive maxillary aspergillosis that presented with epiphora and responded well to surgical treatment is reported. Sixteen percent of cases of chronic sinusitis are produced by mycosis (particularly aspergillosis). The infection may be limited to the affected sinus (non-invasive forms) or may destroy the sinus wall, without tissue invasion (semi-invasive forms) or with tissue invasion (invasive forms). The diagnosis is mainly histological. Cultures present a high percentage of false positives and negatives. Treatment consists of surgical debridement of the sinus. Systemic amphotericin B is reserved for invasive aspergillosis (particularly fulminant cases).

    Title translation The study of the evolution of laryngeal premalignant lesions.
    Abstract Hyperkeratosis of the laryngeal epithelium is considered a clinically premalignant lesion that develops into invasive carcinoma in about 7-20% of cases. We reviewed 125 cases of patients with laryngeal keratosis in biopsy obtained by direct laryngocopy over a 10-year period. The evolution of these lesions to malignancy was conditioned by age, the presence of atypias in the initial lesions, and smoking; smoking is a modifiable factor. Surgery is the treatment of choice, with periodic follow-up for three to five years. The literature was reviewed.

    Title translation Myringoplasty: onlay vs. underlay. Review of 460 cases.
    Abstract A retrospective review was made of 460 myringoplasties performed in our department from 1984 to 1990. In 80%, the perforation closed successfully. There were no differences in site, size, cause, or previous operations. Results were statistically better with the onlay technique than with the underlay technique, particularly in large perforations. Poorer results were obtained in younger patients, a difference that almost reached statistical significance. Hearing improved in 64% of patients with closed perforations and hearing deteriorated in 29% (2.1% complete hearing loss).

    Title translation Mediastinitis secondary to Ludwig's angina. One case report.
    Abstract Ludwig's angina is a cellulitis, usually of odontogenic origin, involving the submandibular space. The number of cases has been heavily lowered since the introduction of antibiotherapy. The treatment consists in an aggressive antibiotherapy and, sometimes, surgical drainage. Complications are: acute respiratory obstruction and spreading of the infection through the neck spaces till the mediastinum. We report one cas complicated with mediastinitis which diagnosis was based in radiological data, basically provided for TAC, The treatment required surgical drainage and antibiotherapy.

    Title translation Acute respiratory obstruction caused by laryngeal rheumatoid arthritis.
    Abstract We present a case of acute upper airway obstruction due to cricoarytenoid arthritis in severe rheumatoid arthritis. Although laryngeal involvement is common in severe rheumatoid arthritis, the upper airway obstruction is a very rare complication. The endotracheal intubation may be very difficult in these patients, thus fiberotopic bronchoscopy may be useful. Surgery is the final treatment.
