| the vasectomy decision-making process. | vasectomy is greatly underutilized in most countries, in part because it is the least promoted of all modern contraceptive techniques. if providers have favorable attitudes toward vasectomy, a good understanding of the decision making process that leads to vasectomy enhances their ability to encourage the use of this method. furthermore, thorough counseling of vasectomy seekers will significantly increase acceptance. the purpose of this article is to define the decision making process and to ... | 1983 | 6845392 |

| usual interstitial pneumonia following texas a2 influenza infection. | in two patients a documented texas a2 influenza infection was associated with the development of interstitial pulmonary disease. one patient had an acute fulminating process resulting in respiratory failure and necessitating ventilatory assistance. open lung biopsy revealed a histologic picture consistent with usual interstitial pneumonia (uip). the other patient had a subacute course, and the pulmonary histology showed uip with features of desquamative interstitial pneumonia. the influenza viru ... | 1981 | 6941880 |
| considerations of the risk of influenza in children and indications for prophylaxis. | the development of effective prophylaxis against influenza virus infections presents a special challenge. stimulation of a protective response apparently requires more than one exposure to the virus. the virus may then change its surface antigens to render ineffective previously acquired immunity. ideally, artificial prophylaxis should stimulate better protection than does natural infection and should anticipate antigenic change. children experience the highest morbidity, accompanied by consider ... | 1980 | 6997968 |
| mortality experience of 161 employees exposed to ethylene dibromide in two production units. | animal studies have indicated the carcinogenic potential of ethylene dibromide (edb). examination of the mortality experience of employees exposed to edb in two production units operated from 1942 to 1969 and from the mid-1920s to 1976, respectively, showed that in the first unit two deaths from malignant neoplasms were observed against 3.6 expected (based on us white male mortality), and in the second unit, where there was potential exposure to various organic bromide products, five deaths from ... | 1980 | 7000159 |
| genetic epidemiology: four strategies. | human genetics has long been preoccupied with the study of simple, single locus traits and, indeed, it is still asserted that "the primary goal of human genetic analysis should be the detection and estimation of single gene effects" (102). but there is increased recognition that the greater portion of the human burden of disease and disability stems not from such conditions but rather those in which the appearance of the disorder is only the last stage in a lifelong train of prodromal states. th ... | 1980 | 7000532 |
| infection with influenza a/victoria virus in houston families, 1976. | in 1976, an epidemic caused by infections with an influenza virus antigenically similar to a/victoria/75 (h3n2) occurred in houston, texas. during this outbreak, 37 families (155 members) enrolled in the houston family study were under observation. the families lived throughout the metropolitan area (houston, texas), and were representative of low income groups. the overall frequency of infection in family members was 27.7%. the frequency of infection was the highest for infants under one year o ... | 1981 | 7016989 |
