Between 1964 and 1984, 430 patients with complex reflux problems were managed by a modified Collis gastroplasty and partial fundoplication. The indications for selecting the addition of gastroplasty were as follows: (1) obvious acquired shortening due to peptic esophagitis and stricture, and (2) subtler degrees of acquired shortening frequently encountered(More)
Using the recent standardization of the pathologic definitions for acute lung rejection, we prospectively evaluated 66 consecutive bronchoalveolar lavage (BAL) and transbronchial biopsy (TBB) specimens in 32 patients after lung transplantation. Clinical indications for bronchoscopies were surveillance (n = 44), rejection (n = 18), and infection (n = 4).(More)
We evaluated the use of total thoracic esophagectomy and replacement with stomach in a group of 21 patients between 1976 and 1986 who had undergone multiple unsuccessful esophageal operations. All patients had between one and four unsuccessful operations for benign esophageal disorders. Sixteen patients had primary motor disorders: achalasia in nine and(More)
Between March 1988 and March 1991, 17 patients underwent bilateral lung transplantation for end-stage lung disease caused by cystic fibrosis. There were 11 male and six female patients. Ages ranged from 19 to 41 years (mean age 28 years). Preoperative mean arterial oxygen tension with the patient breathing room air was 54 +/- 6 mm Hg; forced vital capacity,(More)
Between November 1983 and March 1991, we performed 50 single and 40 double lung transplants in 82 recipients. Early deaths occurred in six (13%) single and in eight (21%) double lung transplant recipients. Late deaths occurred in 11 (28%) single and in one (3%) double lung recipients. Twenty-three of 37 (62%) single and 17 of 24 (71%) double lung transplant(More)
A qualitative and quantitative histological analysis of minor salivary glands was carried out in 60 alcoholics (20 alcoholics with liver damage, 20 without liver damage, 20 young alcoholics) and 20 matched control patients. A sialographic study was carried out in the same 60 alcoholic patients and in 40 non-alcoholic control individuals. Minor salivary(More)
Drawing from social comparison theory, we examine how perceptions of friends’ body sizes may influence adolescents’ subjective evaluations of their own body (e.g., how accurate they are in judging their weight, how much body dissatisfaction they feel), particularly for adolescent females. Participants were low-income, minority adolescents (Study 1: N = 194(More)
A clinical reality since 1981, lung transplantation is now generally accepted as a useful procedure for patients with end-stage lung disease. Early attempts at lung transplantation were marked by infection, rejection, and, in particular, bronchial dehiscence. Obliterative bronchiolitis, an airway-targeted form of chronic rejection, continues to be a(More)
We study by density functional theory the hydrolysis of a chlorambucil analogue. Three SN(1) and one SN(2) mechanisms have been compared. Results show that the most likely mechanism involves the formation of an aziridinium ion via a first-order reaction subject to an energy barrier of 24.8 kcal/mol. Additionally, a kinetic study, using the thermodynamic(More)
