[A case of ASD with SLE treated with Carmeda BioActive surface circuit in cardiopulmonary bypass system].

A 61-year-old woman of ASD complicated with SLE was operated on. We used a heparin coating Carmeda BioActive Surface (CBS) in cardiopulmonary bypass circuit for the purpose to prevent the postoperative complications due to the reduced complement activation by SLE. This system could prevent the decline of the reduced complement activation during cardiopulmonary bypass and after operation. The management of steroid therapy for SLE patient, usefulness of heparin coating CBS system for hypocomplement disease were discussed.

[Valvular surgery for the patients 70 years old or older].

From January 1986 to June 1993, twenty one patients aged 70 years or older with valvular heart disease underwent open heart surgery. There were 12 males and 9 females with a mean age of 71.2 years (range 70 to 76). Eight patients were in NYHA class III, and 4 in class IV preoperatively. AVR was performed in 10 patients, MVR, MVR with TAP, OMC, AVR with MAP, DVR with TAP in 4, 4, 1, 1, and 1, respectively. Mechanical and bioprosthetic valves were replaced in 11, and 9 patients respectively. There were 6 early death (4 operative, 2 hospital). Longer duration of cardiopulmonary bypass (p < 0.05) and aortic crossclamp time (p < 0.05) were the risk factors independently for early mortality. Follow-up of 15 hospital survivors was 100% (8 months-7.7 years, mean: 3.2 years) and cumulative follow-up was 47.6 patients years (PY). There was one late death, and one prosthetic valve endocarditis (2.1%/PY). No other valve-related complications was occurred. Actuarial survival rate and freedom from valve-related morbidity at seven years were 83.3%, and 93.3%, respectively. These results show that operative mortality of valvular disease in elderly patients remains high, but the late results is acceptable one. Valve surgery for these elderly patients is reasonably acceptable.

Atypical liver alcohol dehydrogenase in the Spanish population: its relation with the development of alcoholic liver disease.

The presence of atypical liver alcohol dehydrogenase (ADH) was determined in samples of liver tissue from 222 alcoholic and nonalcoholic subjects to determine its prevalence in the Spanish population, and to evaluate the possible relationship between the presence of this isoenzyme and the development of alcoholism and alcoholic liver disease. Alcoholic patients were classified into the following groups: control subjects, with normal liver pathology (group 1), patients with noncirrhotic liver disease (group 2), and patients with cirrhosis of the liver (group 3). Nonalcoholic subjects were also divided, following the same criteria, into groups 4, 5, and 6, respectively. The prevalence of atypical ADH in the population analyzed was 16.2%. Atypical ADH was present in 14.9% of alcoholics and in 17.4% of nonalcoholics (p = NS). There were no significant differences when the prevalence of atypical ADH of alcoholic and nonalcoholic patients with similar degrees of liver pathology was compared (group 1 vs. 4, group 2 vs. 5, and group 3 vs. 6). The prevalence of atypical ADH was also similar in cirrhotic patients with respect to those of noncirrhotic liver disease and control patients, either in alcoholic or nonalcoholic groups. Our findings indicate that the prevalence of atypical ADH in the Spanish population is similar to that reported for other Caucasian groups. Moreover, the presence of atypical ADH does not play a role in the development of alcoholism nor in the development of alcoholic liver disease in the population analyzed.

[Syncope as presentation form of pulmonary thromboembolism. Study of 15 cases].

BACKGROUND: To evaluate the prevalence of syncope as a form of presentation of pulmonary thromboembolism (PTE) in the emergency department of a general hospital. METHODS: All the cases of PTE having gone to the emergency department between May 1983 and July 1989 were collected. A radiography of the thorax, arterial gasometry, an electrocardiogram and a pulmonary perfusion scintigraphy were performed in each patient. Ventilation scintigraphy and/or pulmonary DIVAS were also carried out when necessary. RESULTS: Of a total of 63 patients, 15 (24%) had a syncope as a primary manifestation. No significant differences were observed in regards to predisposing factors between the syncope group (S) and the non-syncope group (NS) with there being a predominance of women in the S group (p less than 0.05). Furthermore, the S group had a greater prevalence of tachycardia, hypotension, electrocardiographic changes, pleural effusion and perfusion defect greater than 50% in the pulmonary scintigraphy. CONCLUSIONS: PTE should be discarded in any patient with a clinical picture of syncope with hypotension and tachycardia, especially if female. When PTE is presented as a syncope it is generally a massive embolism.

Spontaneous bacterial peritonitis due to Salmonella enteritidis in cirrhotic ascites.

Spontaneous bacterial peritonitis due to Salmonella is uncommon. We report three patients with ascites infected by Salmonella. All three patients had advanced chronic liver disease, typically cirrhosis with portal hypertension. Salmonella enteritidis grew in the ascite fluid culture of the three patients. There was no clinical or microbiological evidence of Salmonella infection other than in the ascitic fluid. One patient died before antibiotic treatment was started, but the other two were treated with different combinations of antimicrobial drugs. One of them died on the fourteenth day of hospitalization, and the other survived.

[Ambulatory control and follow-up of patients carrying a unicameral pacemaker].

The follow-up schedule after pacemaker implantation should be arranged to allow close monitoring during the immediate post-implant period, and frequent observations during the life of the system. Such follow-up has as major goals the evaluation of the electrical functions of the pacing system to detect malfunctions or imminent power source depletion and the evaluation of the patient cardiac status so that reprogramming can be accomplished.

[Surgical treatment of infant atrial septal defect: report of two cases].

The operation for the isolated secundum type of atrial septal defect (ASD) is usually conducted electively in the older age. Small number of cases, however, inevitably require surgical treatment for the reason of intractable heart failure. We have experienced such two infants with the isolated secundum type of ASD, whose conservative treatment was ineffective.

Thoracoabdominal aortic aneurysms repair under abdominal cavity cooling with visceral shunting technique--a case report.

Mild hypothermia induced by abdominal cavity cooling together with a selective visceral shunting technique can be a useful adjunct for thoracoabdominal aortic aneurysm repair. The authors adopted this combined technique for repair of selected Crawford type III and type IV aneurysms to reduce visceral ischemic damage and minimize the incidence of postoperative complications.
