Cost analyses of alternative health examination modes.

Health examinations have become an essential service for a health maintenance organization to provide to ambulatory patients for determining their health status and care needs. Three methods were studied for providing health examinations to 6,285 examinees. Compared with the traditional physical examinations customarily provided by physicians, it was determined that either of two alternative systemized modes proved more economical with regard to both physician time and total resource costs for similar patient groups standardized by age, sex, and health status. The most efficient method of providing health examinations to large numbers of people used multiphasic health testing, followed by physical examinations provided by nurse practitioners supervised by physicians; this required 68% less physician time and resulted in a decrease in total examination costs of 30% as compared with traditional examinations.

Epidemic streptococcal sore throat following a community picnic.

Following a picnic, nearly half of the persons who attended became ill. Sixty-three of 139 throat cultures were positive for group A beta-hemolytic streptococci. Forty-seven of the positive cultures were available for typing, 34 of which harbored the epidemic strain, group A beta-hemolytic Streptococcus type T-3/13/B3264. This contrasted with two of 204 controls who had not attended, but harbored the epidemic strain. Food preferences and illness rates implicated the potato salad, and from it the epidemic strain was isolated. The attack rate and case-to-infection ratio among those who attended the picnic was significantly greater for persons over 10 years of age. Prompt institution of chemoprophylaxis could possibly have prevented at least 50% of the cases.

Evaluation of an ambulatory medical-care delivery system.

We designed a medical-care-delivery system specifically to relieve the impaired access to care that has invariably assompanied the elimination of personal fees by prepaid plans, Medicare and other third-party payment plans. The solution involved the entry of patients through a paramedically staffed health-evaluation servece that effectively separated patients into three basic health-status groups-the well and worried well (68.4 per cent); the asymptomatic sick (3.9 per cent); and the sick (27.7 per cent)--a process that permitted matching the needs of each group with appropriate services. The system achieved increased physician accessibility to new patients by 20 times, reduced the waiting time for new appointments from six to eight weeks to a day or two, saved physician time and costs for entry work to a day or two, saved physician time and costs for entry work-up by 70 to 80 per cent reduced total resources used throughout the year by +32,550 per 1000 entrants, and proved very satisfactory to patients and generally so to staff.

Vascularization induced in the cheek pouch of the Syrian hamster by tumor and nontumor substances.

We tested fresh amelanotic and dry amelanotic melanoma tissue, gelatin, embryo and adult connective tissue, fresh and dry liver, fibrinogen, fibrin, pouch membrane, starch, dry hamster embryo and placental tissue, and glycogen in the transparent cheek pouch chamber of the Syrian hamster to explore the specificity of tumor angiogenesis and the mechanism that may selectively inhibit proliferation of blood vessels in the pouch membrane. Differences between the proliferations induced by tumor and normal tissues, various proteins, and polysaccharides were qualitative as well as quantitative. The glucocorticoid 6 alpha-methylprednisolone (MPS) decreased and sometimes totally inhibited the vascularization phenomenon. Dry tumor tissue induced capillary proliferation in seven of eight chambers 3 days after surgery; two of seven chambers of MPS-treated animals showed a reaction 10 days after the operation. MPS suppressed (in some cases only partially) capillary proliferation in chambers with implants of adult connective tissue, fresh liver, starch, or glycogen.

Staphylococcal bacteremia and hexachlorophene bathing. Epidemic in a newborn nursery.

An outbreak of staphylococcal bacteremia in healthy, full-term neonates occurred in the newborn nursery at a large county hospital not employing prophylactic hexachlorophene bathing. Seven infants had staphylococcal bacteremia and one had omphalitis. Two of the three isolates obtained for phage typing were type 86, and the other was 3c/71. Staphylococcal colonization rate in the nursery was 64% when the outbreak was recognized; 86% of these isolates were type 86. No predominant phage type was isolated from nursery personnel. The outbreak followed a six-month preliminary study that showed a rise in staphylococcal colonization rate from 2.2% with hexachlorophene bathing to 67% with a nonhexachlorophene-containing preparation. In a community survey of infants born during the two months prior to the epidemic, seven of eight babies with lesions were infected with Staphylococcus aureus type 86.

The tumbling bullet sign in a post-traumatic bone cyst.

Various hypotheses for the etiology of unicameral bone cysts are discussed. The unique documentation of a lesion which developed as a result of a bullet wound appears to lend credence to trauma as an inciting agent.
