摘要:
A marked increase in the number of cases of shigellosis was reported in Kentucky in 1988. To examine reasons for this increase, we reviewed the 389 cases of shigellosis reported from 1986 through 1989. Ninety-three percent (285/305) of cases due to known species were due toShigella sonnei.Sixty-two percent (243/389) of cases occurred in children less than 10 years of age. The annual incidence for blacks (6.8 cases per 100 000) was nearly four times that for whites (1.8 per 100 000). The increased number of cases in 1988 was due to outbreaks in five areas of the state, which accounted for 85% (200/234) of the cases. Three of the five outbreaks involved day-care centers. The primary mode of transmission appeared to be person-to-person; there was no evidence of a common source of infection from food or water. To prevent future outbreaks, cases of shigellosis need to be reported promptly to ensure appropriate investigation and control by local health departments.

摘要:
Invasive pulmonary aspergillosis was diagnosed in two patients with HIV infection, one with prolonged neutropenia and another receiving corticosteroid therapy. We found 17 additional cases in the literature. A known predisposing risk factor for invasive aspergillosis, eg, neutropenia, corticosteroid use, or intravenous drug abuse, was present in 79% of the cases. That the known immunologic defect of AIDS is not a major host defense againstAspergillusis supported by the empiric observation of the relative rarity of aspergillosis in patients with AIDS. The lung was the most common site ofAspergillusinfection (75%), and transbronchial biopsy is diagnostically useful. Central nervous system involvement was seen in 55% and appears to be more frequent in HIV-infected patients than in other immunosuppressed patients with invasive aspergillosis. Prognosis is grim. Despite early institution of amphotericin B therapy in a few cases, the disease was uniformly fatal. Efficacy of therapy with amphotericin B plus rifampin or itraconazole remains to be evaluated. We conclude that aspergillosis is not an AIDS-related opportunistic infection.

摘要:
Invasive pulmonary aspergillosis is a well-recognized complication in immunocompromised patients, especially those with neutropenia. We report four cases of invasive pulmonary aspergillosis in patients whose main underlying disease was chronic obstructive pulmonary disease (COPD). Two patients had an acute fatal course, one had chronic necrotizing pulmonary aspergillosis ending in an acute fatal course, and the other had a semiacute disease that responded to amphotericin B. Autopsy on three patients showed invasive pulmonary aspergillosis in both lungs, and tissue invasion was documented by transbronchial biopsy in the patient who survived. Retrospective review of all cultures that grewAspergillusspecies from bronchoscopic specimens showed no false-positive results, and this procedure proved to be the most useful maneuver in making the diagnosis. Invasive pulmonary aspergillosis should be in the differential diagnosis in patients with COPD and unexplained pulmonary infiltrates.

摘要:
To clarify the role of Epstein-Barr virus (EBV) infection and the value of EBV antibody testing in evaluating patients with chronic fatigue, we studied 200 consecutive patients with chronic fatigue (mean duration, 9 years). Complete EBV serologic panels were obtained for 154 patients, 35 (23%) of whom met serologic or clinical criteria for chronic or reactivated EBV infection. We compared these patients with chronic EBV infection (CEBV cases) to 35 age- and sex-matched patients who were selected from the same cohort of fatigued patients but who did not meet the criteria (CEBV control subjects). We found few differences between groups in demographic characteristics, clinical features, and symptoms; CEBV cases were more likely to meet criteria for the proposed chronic fatigue syndrome (14% vs 0%), and to report that they suffered from an influenza-like illness at the onset of their fatigue syndrome (34% vs 12%), that they lost their job because of their fatigue (37% vs 11%), and that their fatigue was improved by recreational activity (26% vs 3%). Physical examination and laboratory testing showed few abnormalities in either group. Psychiatric morbidity was common in both groups, including mood disorders (63% of CEBV cases vs 54% of CEBV controls), anxiety (11% vs 9%) and somatization disorder (9% in each group). We conclude that EBV serologic patterns have little clinical usefulness in evaluating patients with chronic fatigue.

摘要:
Two hundred fifty-eight patients were admitted to the hospital for suspected acute myocardial infarction. Electrocardiograms recorded on admission (initial ECG) and the most recent available electrocardiogram recorded before admission (previous ECG) were compared to determine whether changes from the previous to initial ECG predicted acute myocardial infarction or complications of coronary artery disease. Initial ECGs were classed as either positive or negative, with positive indicating either infarction, injury, ischemia, strain, left ventricular hypertrophy, left bundle branch block, or paced rhythm. Negative ECGs were those that did not include any of the positive criteria. Positive and negative ECGs were subgrouped as showing change or no change from previous ECG. We found that patients with a negative initial ECG that had changed from the previous ECG had a 2.1 times greater risk for requiring interventions than those patients whose ECGs were unchanged. We also found that patients with a positive initial ECG that had changed from the previous ECG had a greater risk for interventions (2.0 times), complications (2.6 times), life-threatening complications (4.2 times), and acute myocardial infarction (6.6 times) than the sum of patients in all other ECG categories. We conclude that change is a useful predictor for interventions in patients with negative initial ECGs and a useful predictor for interventions, complications, and acute myocardial infarction in patients with positive initial ECGs.

摘要:
This is a retrospective study of cardiac patients with noncardiac chest pain referred for evaluation of esophageal motility. Sixty-eight patients with heart disease were compared with 210 patients without heart disease according to findings from symptom questionnaires and a psychologic test (Brief Symptom Inventory). More than 70 % of each group qualified for an anxiety or depressive diagnosis on the symptom questionnaire. These diagnoses were supported by significant elevations of scores on the anxiety and depression scales of the Brief Symptom Inventory. Male gender and a diagnosis of panic disorder occurred significantly more often in the patients with heart disease. “Stress” was cited as the cause of illness in about half the sample, but this led to less than satisfactory rates of psychiatric evaluation or pharmacotherapy. This is of particular concern for the cardiac patients because of the known adverse effect of anxiety and depression in those with heart disease.

摘要:
Immunohistochemical and biochemical assays for estrogen and progesterone receptors were done on 20 breast carcinomas, and results were correlated with various histologic features. The slide-based immunohistochemical technique demonstrated several distinct advantages relative to the tissue homogenization required by the traditional biochemical assay. With the use of frozen tissue sections, the immunohistochemical technique permitted direct visualization of antireceptor binding to tumor cells. Receptor staining of reactive stroma, necrotic tumor, and intermingled benign parenchyma was easily distinguished from receptor staining of the actual carcinoma. This separation is not possible with the biochemical assay. In addition, in situ and invasive components and different morphologic subtypes were evaluated independently. Receptor content of the most aggressive portion of the neoplasm is likely to have the greatest clinical relevance and prognostic significance. Careful correlation of histochemical scores with biochemical assay concentrations is needed to permit the application of this technique to patients entering cancer treatment protocols.

摘要:
The importance of hormone receptors in the management and prognosis of breast cancer is well established, but difficult to apply to the growing numbers of very small breast cancers being detected. To assess the feasibility of applying estrogen receptor immunocytochemical assay (ER-ICA) to cytologic specimens, we prospectively studied 100 patients who had fine needle aspiration biopsy (FNAB) of mammographically detected nonpalpable breast lesions. All 100 patients also had surgical excision of these nonpalpable lesions immediately after cytologic aspiration. Twenty malignancies were ultimately diagnosed by histology; 17 of them had been cytologically diagnosed. Using specific monoclonal antibody for estrogen receptor, we applied ER-ICA to cytologic preparation of 15 malignant neoplasms with sufficient cellular material available for the assay. Positive immunostaining was demonstrated in nine cases. No ER expression was seen in six cases. Immunocytochemical assay was also done on frozen tissue of the corresponding surgically removed tumors, with 86.6% concordance between the two results. This study is the first to demonstrate that ER-ICA can be effective in assessing hormone receptor content of mammographically directed cytologic aspirates.

摘要:
Breast cancer remains a major cause of death among women in South Carolina. Mammography, breast self-examination, and clinical breast examination are effective methods for early detection and subsequent mortality reduction. The Tricounty Breast Cancer Screening Survey assessed knowledge of these methods and recommendations among 503 women in the Charleston area. While 57% of all respondents reported performing breast self-examination at least once per month, 13% of blacks and 6% of whites reported that they do not know how to perform the procedure. Clinical breast examinations within the past year were reported by 69%, yet 11% of blacks and 4% of whites reported that they had never had the examination. More than one third (40%) of all 503 women reported ever having had a mammogram, and 22% reported having had one within the past year. However, 18% of the blacks and 5% of whites reported never having heard of the procedure. The major barriers to mammography appear to be the belief that women do not need regular mammograms and the lack of recommendations by their physicians. Survey results support the need for educating women about what the procedures are, the importance of using them regularly, and the means to comply with them.
