The treatment of perinatal addiction. Identification, intervention, and advocacy.

Women of reproductive age who use and abuse psychoactive drugs and alcohol present a special challenge to primary care physicians. There are compelling medical reasons for identifying and intervening with pregnant women who are addicted or have alcoholism. The teratogenicity of all drugs of abuse and alcohol, the risk of infection with the acquired immunodeficiency syndrome (AIDS), and the potential for full recovery of a pregnant woman from addiction are some of the reasons that identification and intervention in the problem are indicated. Whether encountered in the clinic setting or in private practice, chemically dependent pregnant or postpartum women are usually responsive to appropriate physician interventions that include a detailed and caring confrontation- and advocacy-oriented support. Complex legal and ethical issues surround perinatal addiction including the role of toxicologic screening, reports to child welfare services, issues in noncompliance, and interdisciplinary case management.

Identification and management of potential heart transplant recipients.

Transplantation should be performed to improve the quality and duration of life in patients with end-stage cardiac disease. Symptoms, left ventricular ejection fraction, previous and present medications, and an exercise tolerance test serve as basic screening information to identify potential transplant candidates. Patients need to have a psychological, financial, and behavioral profile that will allow them to withstand the rigors of the entire transplantation process, and have no other medical problems that would jeopardize their survival following transplant surgery. Maintenance of the patient's status while awaiting a cardiac donor begins with patient education and a search into the causes of underlying ventricular dysfunction. Medications subsequently used include diuretic agents, vasodilators, digitalis, anticoagulants, antiarrhythmics, and possibly beta-blocker therapy. When standard measures fail, potent inotropes and even mechanical assist devices are sometimes necessary. Future donor heart allocations will require more rigid criteria for the selection of cardiac transplant candidates.

Cognitive function in patients with symptomatic dilated cardiomyopathy before and after cardiac transplantation.

Pre- and postoperative cognitive performance of candidates for heart transplantation was examined by means of an extensive battery of neuropsychological measures. A total of 54 patients completed the preoperative cognitive protocol, 20 of whom also completed postoperative testing. Age (less than 50 or greater than or equal to 50 years of age) and the primary cause of cardiac deterioration (idiopathic, ischemic disease or rheumatic/congenital defects) were the major classification variables. The main findings of this study were: 1) Preoperative neuropsychological measures revealed a high frequency of impaired performance, particularly in measures of memory, higher level processing of information and motor speed. A pattern consistent with diffuse rather than focal or lateralized cerebral deficits was observed. Significant differences were not found on the basis of the cause of cardiac disease, but some were observed for age (the older group was more impaired). 2) A comparison of pre- and postoperative cognitive scores failed to show significant cognitive improvement despite greatly improved physical health. The cause of cardiac deterioration was not differentially associated with postoperative cognitive performance, and there was equivocal evidence for age effects. These findings may have implications for the selection of transplant recipients and the timing of transplantation surgery.

Endogenous Nocardia asteroides subretinal abscess diagnosed by transvitreal fine-needle aspiration biopsy.

The authors report a case of an endogenous Nocardia asteroides subretinal abscess in an immunosuppressed cardiac transplant recipient. On clinical grounds, the metastatic subretinal abscess was initially thought to be a fungal, atypical bacterial, or viral lesion. Transvitreal fine-needle aspiration biopsy of the lesion yielded a sufficient specimen for immediate preliminary identification of the microorganism and permitted prompt initiation of an appropriate antibiotic regimen. The definitive diagnosis was based on culture of the organism from the needle aspirate.

Managing congestive heart failure.

Congestive heart failure, a constellation of signs and symptoms that result from the heart's inability to provide sufficient oxygenated blood to metabolizing tissues, is a major cause for concern in the elderly. The prognosis is ominous, with a 10% per year mortality rate after the initial CHF episode, and a 30 to 60% per year rate for patients who remain symptomatic despite digitalis and diuretic treatment. Common etiologies in CHF are discussed, and a case history illustrating CHF symptomatology is provided. The role of diuretics, digitalis, ACE-inhibitors, and other pharmacologic agents is reviewed and updated, and the value of patient education is discussed.

Effects of low dose enoximone for chronic congestive heart failure.

To examine the short-term hemodynamic and long-term clinical effects of oral enoximone at low doses, 12 patients with severe, chronic congestive heart failure (CHF) were given 1 mg/kg oral enoximone and followed with serial hemodynamic measurements for 24 hours. Control cardiac index was 1.9 +/- 0.5 liters/min/m2 and it increased significantly by 1 hour, with a peak effect at 2 hours to 2.4 +/- 0.4 liters/min/m2 (p less than 0.05). Similarly, wedge pressure, 22 +/- 8 mm Hg at control, decreased to 16 +/- 10 by 1 hour (p less than 0.05). Six of the 12 patients received 1 mg/kg of enoximone on day 1 and 2 mg/kg on day 2. The higher dose of enoximone caused no further improvement in cardiac performance but prolonged the salutary hemodynamic effect. Subsequently, 79 patients (18 in New York Heart Association class III and 61 in class IV) with CHF (ejection fraction 17 +/- 8%) were followed over a 3 year period; the average enoximone dose was 1.7 +/- 0.7 mg/kg 3 times daily. Improvement of at least 1 functional class occurred in 55 patients (70%) at 1 month, 27 patients (34%) at 6 months and 19 (24%) maintained their improvement for over 1 year. Enoximone was discontinued in 20 patients (25%); in 5 (6%) for adverse effects and in 13 patients because of no clinical benefit. Adverse effects occurred in 14 patients (18%); 6% of all patients required discontinuation of drug. Six month survival was 50%, 42% at 1 year and 30% at 2 years.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of chronic pulmonary hypertension on left ventricular size, function, and interventricular septal motion.

The effect of right ventricular pressure overload secondary to chronic pulmonary arterial hypertension on left ventricular size and function and on interventricular septal motion was studied in 13 patients in whom coronary artery disease, hypertension, and hypoxemia were excluded. Regional and global left ventricular function were assessed by computer-assisted analysis of two-dimensional directed M-mode echocardiograms obtained within 24 hours of a hemodynamic study. Septal position and motion were further analyzed by delineating seven points along the right and left sides of the septum during a single cardiac cycle. All echocardiographic data were compared to those of 10 normal subjects. Mean values for right ventricular systolic, mean pulmonary artery and pulmonary capillary wedge pressures were: 71 +/- 26 mm Hg, 46 +/- 16 mm Hg, and 7 +/- 1 mm Hg, respectively. Septal motion was interpreted from the M-mode echocardiograms as normal in seven patients (group I) and abnormal in the remaining six patients (group II). The only hemodynamic parameter which distinguished these two patterns was delta P, the transseptal systolic pressure gradient across the interventricular septum, which was significantly different (p less than 0.02) in group I (delta P = 65 +/- 16 mm Hg) from that of group II (delta P = 21 +/- 24 mm Hg). As a result of abnormal septal position, the septal-free wall dimensions of the left ventricle were reduced, but there was no evidence of depressed left ventricular performance in these patients. We conclude that resting left ventricular function is well preserved in patients with pulmonary hypertension, despite significant alterations in septal position and left ventricular size.(ABSTRACT TRUNCATED AT 250 WORDS)

Therapeutic jurisprudence: judicial and corrections panel.

Innovative therapeutic initiatives for the treatment of persons with substance abuse problems have been implemented in the criminal justice systems of California and Arizona. Judicial perspectives and reflections on these programs reveal the multiple issues inherent in innovation and day-to-day operations, from collaboration to implementation, including attitudinal shifts, resource allocation, client issues, and the changing role of judges who practice therapeutic jurisprudence. A pioneering program of treatment for dual disorders among male offenders addresses multiple issues in the provision of psychological services in a forensic setting in California.

Addiction in women: prevalence, profiles, and meaning.

Biologic predisposition, stressors in the environment, and the extent and quality of social support in part explain the development of alcoholism and other drug dependencies in women. The nurse's approach to patients and use of effective tools for assessment of alcohol and drug use can result in increased identification and referrals for treatment.
