To estimate the number of adults medically eligible to donate blood, the percent of the general population over the age of 16 deferrable by 13 current American Red Cross donor guidelines was calculated using the best available United States data. Categories examined included age, weight, hematocrit, pregnancy, blood pressure, heart disease, diabetes requiring insulin, male homosexual activity since 1977, intravenous drug use, sexual partner of high-risk group member, recent transfusion, history of cancer, and other (medical, surgical, travel history). Sex-specific total eligibility rates were estimated by serial multiplication of individual eligibility rates (1.0 minus deferral rates) to account for the proportionate overlap of independent categories, with corrections for expected associations between categories. The resultant eligibility rates for women (57%) and men (70%) indicate fewer eligible donors than commonly stated. Surrogate testing (ALT, anti-HBc) for non-A, non-B hepatitis would further reduce the percent of eligible donors to 55 and 67%, respectively. Based on the actual numbers of women and men in the population, these calculations indicate that an equal number of women and men are medically eligible to donate.

A 48 year-old-man, with fulminant hepatitis complicated with myocarditis was treated. Despite intensive care, he died of fulminant hepatitis associated with hepatitis B virus infection. Electrocardiography (ECG) showed myocardial infarction-like changes when he went into a deep coma. Microscopically, scattered foci of myocardial cell damage and cell death associated with clusters of inflammatory cells were present in the heart at autopsy. However, there were no findings related to myocardial infarction and staining for hepatitis B surface antigen and core antigen were nil. The concentration of plasma catecholamine was elevated concomitantly with high level of ECG changes. We consider that abnormal ECGs may reflect a hypersecretion of catecholamine and suggest that our patient had a catecholamine cardiopathy.

In 1814, George Maton, first recognized that a mild illness characterized by rash, adenopathy, and little or no fever was a discrete entity. Henry Veale, in 1866, named the disease rubella. The illness attracted little attention until 1942, when Norman Gregg noticed that first-trimester maternal rubella caused serious birth defects. The full spectrum and impact of rubella embryopathy remained unclarified until rubella virus was isolated in tissue culture in 1962 by two independent groups: Parkman, Buescher, and Artenstein; and Neva and Weller. Using the new tools of the virus laboratory, many investigators concentrated on the consequences of a severe rubella epidemic in 1964, which affected approximately 1% of pregnancies. Newly recognized transient manifestations of congenital rubella infection (CRI) include neonatal thrombocytopenic purpura, hepatitis, bone lesions, and meningoencephalitis and late-emerging sequelae such as diabetes mellitus and progressive rubella panencephalitis added to the cataract, heart disease, mental retardation, and deafness previously defined as due to CRI. Sharp contrasts were documented between the patterns of virus excretion and immune response of postnatal vs. congenital rubella. Licensure and widespread distribution of attenuated rubella virus vaccines in 1969 have prevented epidemic rubella. Pockets of illness remain, even in the United States. Continued effort will be required to eliminate the rubella problem.

To determine the outcome of chronic hepatitis in ESRD we studied all 358 renal transplant recipients and 295 hemodialysis patients treated for greater than 1 year since 1970. The incidence of chronic hepatitis (elevated SGOT for greater than 1 year) was 15% (N = 54) in transplanted and 3.4% (N = 10) in dialysis patients. Forty-eight percent (26) of transplanted and 50% (5) of dialysis patients were HBsAg positive. In the transplanted group, the clinical outcome of chronic hepatitis was significantly better in HBsAg-negative compared to HBsAg-positive patients; 11% died, none from liver disease, and 32% remitted after a mean follow-up from start of liver disease of 77.3 +/- 8.2 months, whereas in the HBsAg-positive group 54% (14) died, nine from liver disease, and one remitted after a follow-up of 90.2 +/- 8.9 months. Adverse prognostic factors (age, duration of diabetes, and heart disease) present before ESRD treatment began were similar in both groups, as was duration of follow-up. Only 14% (2/14) of HBsAg-negative patients progressed to chronic active hepatitis on liver biopsy compared to 71% (15/21) of HBsAg-positive patients. Histological stability in those with serial biopsies occurred in 66% (4/6) of HBsAg-negative patients, but in only 18% (13/16) of HBsAg-positive patients with a similar duration of follow-up. No dialysis patients died from liver disease. We conclude that chronic hepatitis occurs more frequently in transplanted than dialyzed patients, and that HBsAg-negative chronic hepatitis has a more benign, clinical, and histological outcome than chronic HBsAg-positive hepatitis in renal transplant recipients.

Fibrin glue Beriplast was used during cardiovascular surgery in 97 patients. The fibrin seal was used for hemostasis on anastomoses, patches and suture lines. Moreover, the glue was applied for epicardial fixation of aorto-coronary vein grafts to prevent postoperative graft kinking. Following extrapleural ligation of patent duct in premature infants, the parietal pleura was fastened to the thoracic wall to prevent extrapleural pneumothorax or hemorrhage. After accidental dissection of the thoracic duct in infants, leakage of chyle could be sealed successfully in 6 cases. Hemorrhage from the sealed surfaces of suture lines was not observed. Viral hepatitis occurred postoperatively in 2 patients (3% of the operations for acquired heart disease), both of whom had also received clotting factor concentrate and blood transfusion because of postoperative hemorrhage not related to fibrin sealed surfaces. A causal relation between the hepatitis and application of the pasteurized fibrin glue seems very unlikely. Although fibrin glue certainly cannot replace the surgical suture, it appears to be a valuable aid under special conditions.

Modern contraceptive methods are discussed, with special emphasis on oral contraceptives, which are regarded as the most effective. They are also regarded as generally safe, although there are contraindications and the drugs should only be prescribed after careful examination. The need for selecting the drug most suitable for the individual patients, mainly on the basis of the characteristics of the menstrual cycle (suggesting a predominance of estrogen or progestin, within safety limits, such as 50 mcg of estrogen), is emphasized. The examinations required include a general clinical, gynecological, and breast examination, cytology tests, evaluation of the menstrual flow pattern, measurements of arterial pressure, weight, glucose, cholesterol and triglyceride levels, and urine tests. They should be repeated at 6-month intervals, or 3-month intervals in the case of high-risk patients (varicose veins, obesity, heavy smokers, high cholesterol and triglyceride levels, history of jaundice, slight heart condition, clinical or potential diabetes, porphyria or predisposition to uterine myoma). Oral contraceptives are contraindicated in cases presenting a history of thromboembolism, phlebitis, cerebral apoplexy; sickle cell anemia, which indicates a predisposition to thromboembolic accidents; serious liver disease or recent hepatitis; serious heart disease; hormone-dependent neoplasia (breast cancer); predisposition to uterine cancer; erythematous lupus; metorrhagia of unknown origin; psychic disorders, especially of a depressive type. They should also be avoided for 3-4 years after puberty, in order to avoid interfering with the development of the hypothalamus and with growth. A carcinogenic effect of the pill and an increase in the risk of giving birth to abnormal children can be ruled out, although the incidence of abortions due to chromosome anomalies after suspending treatment is rather high (due to the previous inhibition of ovulation, a situation similar to repeated pregnancies at short intervals, which involve the same risk).

Among 2175 patients seen over the last three years in a non-specialized department of internal medicine with no intensive care unit, 100 had supranormal serum lactic dehydrogenase activities. These patients' case-reports have been analyzed. Nearly half the patients (47/100) had a malignant disease (cancer or hemopathy). Among the remaining patients, 19 had a hepatic disorder (alcohol hepatitis in 10, viral hepatitis in 8, and isoniazide hepatitis in 1), 7 had a heart disease (heart failure with hepatomegaly in 5, myocardial infarction in 2), and 27 had various other conditions (including hemolysis in 6 and polymyositis en 3). The value of serum LDH assay is obvious in situations other than acute conditions such as myocardial infarction of pulmonary embolism; these are better known and have not been studied here as their prevalence was low among the patients enlisted in our study. In comparison to other enzymes (alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), transaminases (GOT, GPT) that were also routinely assayed in our patients, abnormal serum LDH activities are much less common and their significance is quite different. An increase in serum and their significance is quite different. An increase in serum LDH activity indicates a serious condition, often with a fatal outcome. The "various other conditions" group includes patients with hemolysis, hepatitis and myositis; the other patients in this group either had severe infectious diseases or died suddenly in the first few days of their hospitalization before diagnosis had been established. Each etiologic group has been analyzed to asses the characteristics of patients with increased LDH activity according to each etiology. Analysis of coincident abnormalities of the other enzymes listed above shows marked differences between etiologic groups; diagnostic accuracy can thus be enhanced in certain conditions. Most patients with malignancies had poorly differentiated tumors, with metastases: 28 had an epithelial tumor, with hepatic and/or bone metastases in 23 cases, 5 had cancer of the liver, 10 had a malignant hemopathy (2 lymphomas, 5 myeloproliferative syndromes, 3 acute leukemias), and 4 had a sarcoma. Cancer of the lung is the most common malignancy (10 cases) and may be responsible for increased serum LDH activity even in patients without metastases. Serum LDH assay is of value for monitoring the course in patients with initially increased activities as it falls under effective therapy and rises during exacerbations.

Myocarditis may be a serious extrahepatic complication of hepatitis. In this fatal case of serologically documented hepatitis B viral hepatitis, acute myocarditis was present, with histologic features consistent with a viral pathogenesis. Hepatitis B surface antigen was demonstrated by immunoperoxidase methods in small intramyocardial vessels, suggesting that hepatitis B virus infected the heart. The resulting inflammatory heart disease may have been caused either directly, by virus infecting the myocardium, or indirectly, by an immune-mediated mechanism.

Patients with renal failure have characteristic systemic and oral conditions that require special precautions during dental treatment. Drugs must be administered with caution and patients undergoing hemodialysis must receive special consideration. Both hemodialysis and transplant patients must be protected against infection. This is achieved by early, aggressive, and thorough dental treatment. Use of antibiotics during dental treatment is essential in transplant patients and is often necessary in hemodialysis patients to protect them against bacteremia. Bacterial endocarditis is a concern in patients with renal failure and with heart disease and, in these patients, antibiotic prophylaxis is essential. Hepatitis is often present in patients with renal failure, and precautions should be taken against its spread. Before dental treatment of patients with renal failure is begun, the dentist should consult the patient's physician regarding specific precautions. A treatment plan should be constructed which best restores the patient's dentition and protects from potentially severe infection of dental origin.

Q fever is an important zoonosis caused by the rickettsial organism Coxiella burnetii, which can result in life threatening illness, especially in those with an underlying cardiac defect. C. burnetii infections in England and Wales reported to the PHLS Communicable Disease Surveillance Centre between 1984 and 1994 were reviewed. A total of 1117 cases were reported, a third of which came from the South Western region. The annual totals fell over this period. The mean age of cases was 45 years, and 74% were men. Reports peaked in the month of May. Contact with animals, mainly cattle and sheep, was reported in 60 cases. Occupationally acquired infection was reported for 24 cases including abattoir workers, farmers, veterinary surgeons, hide handlers, and butchers. Forty-seven per cent of cases presented with respiratory symptoms, 7% with heart disease, and 5% with hepatitis. Seven per cent of cases reported travel abroad before becoming ill. Joint veterinary and medical investigations should be undertaken to establish the natural history of C. burnetii infection in England and Wales and formulate policies to prevent acute and chronic infections.
