Correctional health care as a vital part of community health.

Correctional facilities afford health professionals an opportunity to serve a segment of society that may not otherwise come into contact with the health care system. This article illustrates why it is imperative that screenings for infectious diseases be conducted in correctional facilities and/or treatment administered before detainees are released back into the general population. Correctional facilities should be included as alternative health stations to improve community health.

Primary and secondary syphilis in the metropolitan area of Nashville and Davidson County, Tennessee: 1996 to 1998 epidemic described.

BACKGROUND: Metropolitan Nashville, Tennessee experienced a syphilis epidemic from 1996 to 1998. GOAL: This study describes the syphilis epidemic during this period. DESIGN: Descriptive analyses of syphilis surveillance data (1988-1998) were performed, with emphasis on the current epidemic (1996-1998), and were stratified by age, gender, race, and census tracts. RESULTS: Five features were observed regarding the 1996 to 1998 syphilis epidemic: (1) males and females were almost equally affected, with a delay in diagnosis in female patients; (2) the 30-39-year age group was most affected; (3) the 15-19-year age group had the highest percentage increase in incidence; (4) African Americans were the most affected population subgroup; and (5) downtown Nashville and the surrounding areas were most affected. CONCLUSION: Although talk of eradicating syphilis has surfaced nationally, Nashville has continually faced syphilis as a public health problem. During each of the past 3 years (1996-1998), the incidence of syphilis in this community has reached epidemic proportions.

Effect of acetabular component orientation on recurrent dislocation, pelvic osteolysis, polyethylene wear, and component migration.

We retrospectively reviewed 75 total hip arthroplasties to examine the effect of acetabular component position. In group A, 38 of the components were implanted according to manufacture's instructions with all peripheral fins in contact with acetabular bone; as such, the acetabular components were in a relatively vertical position with a mean angle of inclination of 61.9 degrees. Three of these patients developed recurrent dislocations necessitating revision of the acetabular component. In group B, 37 hips, a more horizontal orientation was used despite the fact that all of the peripheral fins of the acetabular component did not engage acetabular bone; in this group the mean angle of inclination was 49.7 degrees. Only one of these hips recurrently dislocated and required revision. There were no problems in this group associated with provisional component stability caused by inadequate peripheral fixation. Radiographs of all patients were obtained at 4 years after surgery (range, 4.0-4.3 years). Pelvic osteolysis had occurred in 24% of hips in group A and 13% of group B. Asymmetric polyethylene wear was observed in 5.1% of the hips in group A; no hip in group B showed wear asymmetry. Acetabular component migration developed in 19% of group A hips and 5% of group B hips. The Mayo clinical hip score was excellent in both groups: group A 71/80, group B 73/80. At an intermediate follow-up it is clear that significant problems can be encountered when this component is positioned in a relatively vertical position to facilitate engaging all four peripheral fins in bone. We have addressed this problem by placing the cup in a more anatomic position of inclination while maintaining provisional rim fixation. This has resulted in a decreased incidence of pelvic osteolysis and fewer complications overall.

Morphologic, hemodynamic and coronary perfusion characteristics in severe left ventricular hypertrophy secondary to systemic hypertension and evidence for nonatherosclerotic myocardial ischemia.

Patients with the clinical diagnosis of ischemic heart disease who were found to be free of significant coronary artery atherosclerotic disease (n = 150) underwent coronary vasodilator reserve testing, 2-dimensional echocardiography, and dipyridamole limited-stress thallium testing. After exclusions (predominantly for technically poor coronary artery Doppler signals or suboptimal echocardiography), 100 patients formed the study population. The purpose was to characterize typical cardiac and coronary artery findings in hypertensive patients with severe left ventricular (LV) hypertrophy (n = 15) and to investigate the evidence for myocardial ischemia unrelated to coronary atherosclerosis in early and advanced hypertensive heart disease. Normotensive and hypertensive control groups without LV hypertrophy (n = 12 and 34, respectively) were used for comparison. Severe LV hypertrophy was defined as LV mass index greater than or equal to 50% above established gender specific norms using 2-dimensional-directed M-mode echocardiography and the cube equation corrected to agree with necropsy estimates of mass. Clinical characteristics more often associated with severe LV hypertrophy were black race (67%), diabetes mellitus (33%), proteinuria (47%) and elevated creatinine (1.5 +/- 0.9 mg/dl). Baseline electrocardiograms and dipyridamole limited-stress thallium scans were highly likely to be abnormal (94 and 73%, respectively). Both eccentric and concentric cardiac hypertrophies were found in the severe group. Ejection fraction was significantly lower (0.51 vs 0.68, p = 0.002) and basal coronary flow velocity higher (12.0 vs 5.0 cm/s, p = 0.0004) among these patients when compared with normotensive control patients. Coronary flow reserve did not differ between control groups but was significantly depressed in patients with severe LV hypertrophy (2.5 vs 3.9, p = 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Congestive heart failure with normal ejection fraction. A different mechanism requiring different therapy.

Clinicians must remain undaunted when history, physical examination, and chest radiography suggest congestive heart failure but left ventricular systolic function is normal. Many of these patients have diastolic dysfunction, and standard therapy for left ventricular systolic dysfunction is often ineffectual or detrimental. Noninvasive testing is subject to many pitfalls but may confirm a clinical suspicion and provide indications to treat or to proceed with invasive testing. In the absence of clinical signs and symptoms of congestive failure, however, abnormal diastolic indexes should not be interpreted as diagnostic of diastolic dysfunction and are not an indication to treat.

Management of coronary heart disease in the elderly.

The prevalence of coronary heart disease (CHD) increases rapidly with advancing age and remains the major cause of death among elderly Americans. The number of elderly has doubled in the last 30 years and is projected to continue growing at more than twice the rate of the general population. The resources required in managing CHD in this population will reach astronomical levels during the next few decades and will severely tax our ability to provide adequate medical care to all citizens, unless cost effective diagnostic and therapeutic strategies are developed which do not severely compromise health care. Risk factors for CHD should be identified and modified as early in life as possible. Modification of risk factors begun at advanced age appears to confer benefit, however. Anti-ischemic drug therapy is the treatment of choice for patients with mild or moderate stable angina. Select elderly may be willing to accept the increased risks of coronary revascularization to achieve relief from debilitating angina or prolongation of life. Physicians must use care in planning diagnostic and therapeutic strategies. Quality of life and independence are often more important considerations than longevity in this age group.

Pathophysiology and management of unstable angina.

Significant progress has been made in recent years in unraveling the dynamic mechanisms involved in the production of unstable angina. This knowledge, and advances in medical and interventional therapy allow the formulation of treatment strategies aimed at specific pathogenic mechanisms and promise to reduce mortality and morbidity. This review covers the diagnosis, pathogenesis, risk stratification, and therapy of unstable angina.

A national survey of complications associated with suction lipectomy: a comparative study.

In March of 1988, a survey form was sent to all 2695 U.S. and Canadian members of the American Society of Plastic and Reconstructive Surgeons. Nine-hundred and thirty-five members responded, for a response rate of 34.7 percent. The purpose of the survey was to ascertain the total number of major liposuction, dermatolipectomy, and abdominoplasty procedures performed from January of 1984 to January of 1988 and to compare nine specific complications that are associated with these three procedures. The 935 surgeons reported a total of 112,756 procedures performed: major liposuction (75,591), dermatolipectomy (10,603), and abdominoplasty (26,562). Nine major complications were surveyed: mortality, myocardial infarction, cerebrovascular accident or transient ischemic attack, pulmonary thromboembolism, fat embolism, major skin loss, anesthesia complication, transfusion complications, and deep venous thrombosis. The findings in this survey showed, when comparing these three procedures and the nine types of complications, that the complication rate for major suction lipectomy was 0.1 percent, for dermatolipectomy 0.9 percent, and for abdominoplasty 2.0 percent. Fat emboli did not prove to be a significant factor associated with any of the three procedures. However, of the 15 reported deaths (major liposuction 2, dermatolipectomy 2, and abdominoplasty 11), pulmonary thromboembolism was the causative factor in 9 deaths (60 percent). Based on these analyzed data, we feel that major suction lipectomy has a low complication rate and is a reasonably safe procedure.
