| primary care physicians' refusal to care for patients infected with the human immunodeficiency virus. | we conducted a telephone survey of a random sample of office-based primary care physicians in los angeles county to determine their practice experiences with patients infected with the human immunodeficiency virus (hiv). telephone interviews included questions related to the physicians' experiences evaluating patients for hiv infection during the past 6 months and the presence of hiv-infected patients in their practices. those without hiv-infected patients were asked if this was because they had ... | 1992 | 1734595 |
| determinants of condom use among junior high school students in a minority, inner-city school district. | condoms reduce the risk of human immunodeficiency virus (hiv) transmission; however, their use among adolescents has been inconsistent. little is known about factors which motivate consistent condom use, particularly among younger adolescents. in a study designed to identify such factors, 1899 inner-city junior high school students were surveyed. in june 1988, students completed an anonymous self-report questionnaire assessing hiv-related knowledge, attitudes, and behaviors. among sexually activ ... | 1992 | 1734383 |
| behavioral risk factor survey of vietnamese--california, 1991. | since 1975, an estimated 979,700 refugees from vietnam and other southeast asian countries have immigrated to the united states (l. bussert, office of refugee resettlement, u.s. department of health and human services, personal communication, 1991). although public health agencies have reported extensively on the occurrence of infectious diseases in these populations (1-4), the prevalence of risk factors for noninfectious health concerns (e.g., heart disease, cancer, and unintentional injuries) ... | 1992 | 1732712 |
| update: influenza activity--united states, 1991-92 season. | from october 23, 1991, through january 18, 1992, 46 state health departments reported regional or widespread influenza activity for 1 or more weeks. for the week ending january 4, 34 states reported regional or widespread activity, the most during any single week this season. from late october through mid-december, influenza outbreaks reported from 11 states involved primarily school children. reports of outbreaks among adults began in mid-november and continued through january and involved pers ... | 1992 | 1731184 |
| prevalence of hepatitis c virus antibodies among patients infected with human immunodeficiency virus. | a study was undertaken to determine the prevalence and risk factors for serological evidence of hepatitis c virus (hcv) infection in patients infected with the human immunodeficiency virus (hiv). tests for anti-hcv antibody were carried out by enzyme-linked immunoassay (eia) on 101 hiv-infected patients from two university-based outpatient clinics. anti-hcv antibody reactive samples were tested by using a recombinant immunoblot assay (riba) for hcv antibodies. fourteen of 101 (13.9%) hiv-infecte ... | 1991 | 1715384 |

| htlv-i-associated myelopathy in a californian: diagnosis by reactivity to a viral recombinant antigen. | a male patient developed leg numbness and weakness, and bowel, bladder, and erectile dysfunction. examination revealed an isolated thoracic myelopathy, with lower-extremity spasticity, decreased vibration and position sense, hyperreflexia, and babinski's signs. serum and csf showed antibody reactivity to human t-cell lymphotropic virus type i or ii (htlv-i/ii), suggesting htlv-i-associated myelopathy. antibody reactivity to a unique htlv-i recombinant protein provided definitive diagnosis of htl ... | 1991 | 1706492 |
| high fecundity of amenorrhoeic women in embryo-transfer programmes. | there is uncertainty over whether the steady decline in human fertility with increasing maternal age is due to quality of the oocyte or of the endometrium. to clarify the issue age-related implantation and pregnancy rates in two embryo-transfer programmes were examined in relation to embryo quality and type of menstrual cycle. in both the uk and the us programmes rates were higher in previously amenorrhoeic (acyclic) women than in eugonadal women, irrespective of age and number of embryos replac ... | 1991 | 1677120 |
| determinants of genital human papillomavirus infection in young women. | carcinoma of the cervix has several well-established epidemiologic risk factors, including multiple sexual partners and early age at first intercourse. human papillomavirus (hpv) infection appears to have an etiologic role in the development of cervical neoplasia, but evidence linking hpv infection to known risk factors for cervical cancer has been inconsistent. the lack of expected correlations may be due to the inaccuracy of hpv assays previously used. a polymerase chain reaction dna amplifica ... | 1991 | 1649312 |
| arboviral infections in the united states. | arboviruses are important considerations in the differential diagnosis of encephalitis and other acute infections. alterations in the environment and in human behaviors contribute to changing patterns of arboviral transmission. these trends, the periodic epidemic resurgence of arboviral diseases such as st. louis encephalitis, and the discovery of new arboviruses present a continued challenge to infectious disease clinicians. | 1991 | 1646839 |
| cholesterol treatment practices of primary care physicians. | the active involvement of primary care physicians is necessary in the diagnosis and treatment of elevated blood cholesterol. empirical evidence suggests that primary care physicians generally initiate dietary and pharmacological treatment at threshold values higher than is currently recommended. to determine current treatment thresholds and establish factors that distinguish physicians who are more likely to initiate therapy at lower cholesterol values, 119 primary care physicians in four northe ... | 1992 | 1641441 |

| the nuts and bolts of organizing and initiating a pediatric transport team. the sutter memorial experience. | specialized interfacility transport teams are capable of delivering critical care medicine to the patient at the referring hospital and while en route to the tertiary care center. to do so effectively, however, requires adequate financial and human resources; management of equipment, supplies and personnel; ongoing education for transport team members; and an aggressive quality assurance program. team members and team management should always be prepared for worst-case scenarios, and develop a m ... | 1992 | 1638435 |
| typhus and typhuslike rickettsiae associated with opossums and their fleas in los angeles county, california. | the recent discovery of cat fleas (ctenocephalides felis) infected with a typhuslike rickettsia (designated the elb agent) raises the question of whether similar rickettsial infections exist in wild cat flea populations. we verified the presence of the elb agent and rickettsia typhi in urban and suburban areas of los angeles, calif. opossums trapped in close proximity to the residences of human murine typhus cases in los angeles county and other areas within the city of los angeles were tested f ... | 1992 | 1629332 |
| risk of needlesticks and occupational exposures among residents and medical students. | occupational exposure to human immunodeficiency virus (hiv) disease is a problem of concern to all health care workers, especially those in large urban teaching hospitals with large numbers of hiv-positive patients. | 1992 | 1627024 |
| compliance with infection control procedures among california orthodontists. | we conducted a survey of a random sample of california orthodontists and of general dentists to compare their infection control procedures. questionnaires were returned by 124 orthodontists (56% response rate) and 126 general dentists (61% response rate). eighteen questions were asked covering practice profile, perception of risk from hepatitis b virus (hbv) and human immunodeficiency virus (hiv), exposure to blood, barrier protection used, and sterilization and disinfection procedures. gloves a ... | 1992 | 1626533 |
| first isolation of borrelia burgdorferi in southern california. | the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was isolated from the blood of a dusky-footed wood rat, neotoma fuscipes baird, in the san bernardino mountains of southern california. antigenic, protein, and molecular analyses demonstrated that the isolate varied slightly from most isolates of b. burgdorferi from northern california and was clearly distinct from other species of borrelia that are endemic to the state. this is the first reported iso ... | 1992 | 1625299 |
| epidemiologic studies on human and feline toxoplasmosis. | human serological profiles, and feline serological and fecal profiles were used to study the epidemiology of toxoplasmosis in santa clara county, california. the prevalence of human toxoplasmosis was determined to be 42.9% in a test population of 147 women. the prevalence of feline toxoplasmosis was indicated to be 34.8% based on serological analysis of 158 felines. of 107 cats tested, 6.5% were shedding toxoplasma gondii - like oocysts in their feces. statistical analyses of questionnaire data ... | 1992 | 1619292 |
| communication campaigns to change health-related lifestyles. | the north karelia project in finland and the stanford heart disease prevention program in california are 2 communication campaign examples for achieving health-related life styles. in 1972, health workers began a heart disease risk reduction program in north karelia which had the highest levels of cardiovascular disease in finland which in turn had the highest rate in the world as a pilot project to test the feasibility of involving the local community. in 1971, the stanford heart disease prog ... | 1992 | 1618514 |
| human rabies--california, 1992. | on may 8, 1992, an 11-year-old boy died of rabies encephalitis in fresno county, california. this was the 10th case of human rabies in the united states since 1980 known to be acquired outside the country and the first case reported in california since 1987. this report summarizes the investigation of the case. | 1992 | 1608395 |
| maxillary canine/third premolar transposition in a prehistoric population from santa cruz island, california. | canine/premolar transposition is rare in both historic and prehistoric homo sapiens with a known occurrence of less than 0.10%. this report describes a prehistoric population sample from one site (scri-3) on santa cruz island, california in which the rate of c/p3 transposition is greater than eight percent, based on nine of 106 adult crania which exhibit the anomaly either uni- or bilaterally. as a means of investigating the etiology of this anomaly, the location of the canine root in adult cran ... | 1992 | 1605313 |
| lyme disease in california: a novel enzootic transmission cycle of borrelia burgdorferi. | knowledge of zoonotic transmission cycles is essential for the development of effective strategies for disease prevention. the enzootiology of lyme disease in california differs fundamentally from that reported from the eastern united states. woodrats, not mice, serve as reservoir hosts, and ixodes neotomae, a nonhuman-biting tick, maintains the agent of lyme disease, borrelia burgdorferi, in enzootic cycles. the western black-legged tick, ixodes pacificus, is the primary vector to humans, but i ... | 1992 | 1604318 |
| impact of height and weight on life span. | the study was conducted to evaluate one aspect of the entropy theory of aging, which hypothesizes that aging is the result of increasing disorder within the body, and which predicts that increasing mass lowers life span. the first evaluation of the impact of human size on longevity or life span in 1978, which was based on data for decreased groups of athletes and famous people in the usa, suggested that shorter, lighter men live longer than their taller, heavier counterparts. in 1990, a study of ... | 1992 | 1600586 |
| occupational exposure to human immunodeficiency virus and hepatitis b virus: a comparative analysis of risk. | to estimate the occupational risk from infection with the human immunodeficiency virus (hiv) in terms of loss of (quality-adjusted) life expectancy, and to compare that risk to those posed by other hazards faced by health care workers. | 1992 | 1580297 |
| hormone pattern in pharmacologically feminized male transsexuals in the california state prison system. | the hormonal profile of 40 transsexual inmates from a pool of 86 inmates in the california state prison system was studied before and after therapy with feminizing hormones. clinical and social data were obtained on all 86 inmates; the incidence of human immunodeficiency virus (hiv) seropositivity was examined in 76 of the 86 individuals. despite similar degrees of feminization in all 40 individuals in whom hormonal studies were performed, variable suppression of serum testosterone concentration ... | 1992 | 1578499 |
| prioritizing candidate reproductive/developmental toxicants for evaluation. | to provide a rational method for the timely evaluation of possible reproductive/developmental toxicants, a prioritization scheme was developed by the california department of health services to select chemicals for consideration by the proposition 65 scientific advisory panel. initially, four ascertainment methods were used to identify and construct a master list of 164 candidate agents. using two criteria, the potential for human exposure and the perceived reproductive/developmental hazard as j ... | 1992 | 1562806 |
| a comparison of hiv-1, hbv, and htlv-i/ii seroprevalence rates of injured patients admitted through california emergency departments. | to determine the seroprevalence rates of hepatitis b virus (hbv) and human t-lymphotropic virus (htlv-i/ii) and to compare these rates with the hiv-1 seroprevalence rate in a sample of injured patients admitted through ten california emergency departments. | 1992 | 1554177 |
| uncertainties in health-risk assessment: an integrated case study based on tetrachloroethylene in california groundwater. | population risk to an environmental contaminant is represented as the product of a source term; the exposure function, which converts the source into a lifetime-equivalent contact rate in the population; the fraction metabolized; the toxic potency associated with the delivered dose; and the size of the exposed population. using case studies for contamination of groundwater in california with tetrachloroethylene (pce), the combined uncertainty in exposure and dose-response models is characterized ... | 1992 | 1553416 |
| argas (argas) monolakensis, new species (acari: ixodoidea: argasidae), a parasite of california gulls on islands in mono lake, california: description, biology, and life cycle. | argas (argas) monolakensis, n. sp., is described from adults, nymphs, and larvae collected from under and around nests of california gulls, larus californicus lawrence, on islands in mono lake, mono county, calif., and from specimens reared in the laboratory. this species is closely related to a. cooleyi kohls & hoogstraal, a parasite of cliff swallows, hirundo pyrrhonota vieillot, but is easily distinguished by hypostome dentition and roof of haller's organ in all stages and chaetotaxy of the l ... | 1992 | 1552533 |

| fear of dying and hiv infection vs hepatitis b infection. | accidental exposure to the blood of hepatitis b patients produced less fear than does accidental exposure today to the human immunodeficiency virus (hiv), even though both have an approximately equal overall risk of death (approximately 1%). subjects responding to hypothetical insect-exposure and disease-exposure scenarios chose to avoid the hiv-type risk of 1% chance of exposure/100% chance of death. fear of certain death seems to account for the greater concern about exposure to hiv than to he ... | 1992 | 1546780 |
| seroprevalence of hiv-type 1 in a northern california health plan population: an unlinked survey. | we conducted an unlinked seroprevalence survey for human immunodeficiency virus-type 1 (hiv-1) of 9821 persons who had a routine personal health appraisal examination in 1989 while members of the kaiser permanente medical care program in northern california. an outside laboratory performed enzyme immunoassay (eia) analyses, and the california viral and rickettsial diseases laboratory confirmed eia-reactive samples by immunofluorescent assay and western blot assay. only 20 specimens (0.2%) were c ... | 1992 | 1546773 |
| augmentation mammaplasty and breast cancer: a 5-year update of the los angeles study. | we have previously reported on the risk of breast cancer in women during the first few years following cosmetic augmentation mammaplasty and are now presenting results after longer exposure. long-term carcinogenicity of breast implants in humans has not been assessed previously. we conducted a retrospective cohort study of 3112 patients with a median of 10.6 years of postimplant experience (range 0.1 to 31.7 years). patients were enrolled from surgeons' records, and cancer outcomes were monitore ... | 1992 | 1546077 |
| evaluation of domestic pigeons as sentinels for detecting arbovirus activity in southern california. | flocks of sentinel domestic pigeons (columbia livia) detected increases in st. louis encephalitis (sle) and western equine encephalomyelitis (wee) virus activity in southern california concurrently with flocks of sentinel chickens. however, occasional low-titered, transient seroconversions to both wee and sle viruses also occurred in pigeons during periods when virus activity was not detected by seroconversions in sentinel chickens, by virus isolation from culex mosquitoes, or by human disease. ... | 1992 | 1536386 |

| regulation of priority carcinogens and reproductive or developmental toxicants. | in california, 370 carcinogens and 112 reproductive/developmental toxicants have been identified as a result of the state's safe drinking water and toxic enforcement act of 1986. they include pesticides, solvents, metals, industrial intermediates, environmental mixtures, and reactive agents. occupational, environmental, and consumer product exposures that involve these agents are regulated under the act. at levels of concern, businesses must provide warnings for and limit discharges of those che ... | 1992 | 1463026 |
| men's disclosure of hiv test results to male primary sex partners. | we evaluated disclosure of human immunodeficiency virus (hiv) antibody status to a main sex partner and the impact on the relationship in men who have sex with men and who are enrolled in the acquired immunodeficiency syndrome (aids) community demonstration projects cohorts. eighty-nine percent of both seronegative and seropositive men disclosed the results to their main sex partner. seventy percent of the seronegative men and 82% of the seropositive men who did so reported that the relationship ... | 1992 | 1456347 |
| aids (hiv) risk assessment in an inner-city women's clinic. | risk assessment and antibody testing are potential modalities through which interventions to reduce heterosexual and perinatal transmission of human immunodeficiency virus (hiv) can occur. more than 98% of women attending inner-city adult gynecology, adult contraception and teen family planning clinics successfully completed self-administered hiv (aids) risk assessment questionnaires and received individual counseling, risk-reduction education and referral for antibody testing. fourteen percent ... | 1992 | 1453406 |
| screening women of childbearing age for human immunodeficiency virus. a cost-benefit analysis. | in light of the increasing problem of perinatal human immunodeficiency virus (hiv) transmission, the issue of screening women for hiv is receiving considerable attention. we analyzed the costs and benefits of screening women of childbearing age for hiv. the analysis was based on a dynamic model of the hiv epidemic that incorporated disease transmission and progression, behavioral changes, and effects of screening and counseling. we found that the primary benefit of screening programs targeted to ... | 1992 | 1444682 |
| high-risk sexual behavior and condom use among gay and bisexual african-american men. | little is known about the human immunodeficiency virus (hiv) high-risk sexual practices of gay and bisexual african-american men. these data are needed so that better interventions can be developed and implemented in this population. | 1992 | 1443298 |
| health care use by human immunodeficiency virus-infected students at a california student health service. | we report characteristics of 16 college students with human immunodeficiency virus (hiv) infection but without the acquired immunodeficiency syndrome who received care at a student health center at a major university in california. sociodemographic and clinical data and medical expenditures were obtained retrospectively from medical charts and computerized billing records. all 16 students were men who had sex with men, and 3 had also used intravenous drugs. dermatologic conditions, upper respira ... | 1992 | 1413741 |
| risk for aids in multiethnic neighborhoods in san francisco, california. the population-based amen study. | to examine the actual and potential spread of human immunodeficiency virus (hiv) from an acquired immunodeficiency syndrome (aids) epicenter to surrounding neighborhoods, we studied the prevalence of the viral infection and aids risk behaviors from 1988 to 1989 in a representative sample of unmarried whites, african americans, and hispanics living in san francisco. we surveyed 1,770 single men and women aged 20 to 44 years (a 64% response rate) in a random household sample drawn from 3 neighborh ... | 1992 | 1413740 |
| the risk management of infections. | unfortunately, risk management, that is avoiding lawsuits, is a retro-active pastime instead of being pro-active. what this means is that we often take action only after a problem has manifested itself, rather than identifying potential problems and correcting them. this is, however, only human nature and occurs in most other walks of life. in dental malpractice, what appears to have been happening during the past few years in california is that plaintiff's lawyers have identified a problem and ... | 1992 | 1389588 |
| molecular cloning and sequence analysis of an isolate of hepatitis c virus from southern california, u.s.a. | we obtained a cdna clone representing a partial rna sequence of a human hepatitis c virus (hcv) isolate from southern california. rna was extracted from the liver tissue of a patient with post-transfusion hepatitis, and used for cdna synthesis and polymerase chain reaction (pcr) amplification using oligonucleotide primers specific for the prototype hcv rna. the cdna clone obtained contains 585 base pairs of hcv sequences and represents the region encoding the putative nonstructural protein ns3 o ... | 1992 | 1364214 |
| seroepidemiology of california and bunyamwera serogroup bunyavirus infections in humans in california. | several human populations in california were surveyed cross-sectionally and longitudinally for neutralizing antibodies to selected arthropod-borne bunyaviruses in the california and bunyamwera serogroups. overall, the prevalence of antibodies to california serogroup viruses was 6.4% in 702 individuals sampled during 1963-1988. comparative antibody titers in individual sera indicated that 4.1% and 1.6% of these infections were caused by viruses similar or identical to jamestown canyon and califor ... | 1992 | 1357960 |
| forecasts of the costs of medical care for persons with hiv: 1992-1995. | this study concludes that the cumulative (national) cost of treating all persons with the human immunodeficiency virus (hiv) rose considerably over the past year and will continue to rise over the next several years. it is forecast that the cumulative cost of treating all persons with hiv will increase 48% from 1992 to 1995 (from $10.3 billion to $15.2 billion). it is estimated that the average yearly cost of treating a person with aids is $38,300 and of treating an infected person without aids ... | 1992 | 1356925 |
| serum epoxide hydrolase (preneoplastic antigen) in human and experimental liver injury. | reports of an increase in a serum epoxide hydrolase (seh), immunochemically related to microsomal eh in humans and rats with hepatocellular carcinoma (hcc), suggested its use as a serum marker for this disease. we have now measured seh levels (as either immunochemically determined content or enzyme activity) in a number of human and experimental models of liver disease. seh was elevated above the normal range in at least 50% of individuals with hcc, including: 3 of 6 northern californians; 4 of ... | 1992 | 1339049 |
| comparison of indirect immunofluorescence and membrane fluorescence assays for the differentiation of antibodies to human immunodeficiency virus types 1 and 2. | serum samples from 20 human immunodeficiency virus type 1 (hiv-1)- and 30 hiv-2-infected and 7 dually infected individuals were reacted by using the indirect immunofluorescence assay (ifa) and membrane fluorescence assay in order to determine whether these methods were useful for typing hiv-1 and hiv-2 antibodies. although 41 of 50 (82%) of the hiv-1- and hiv-2-positive specimens cross-reacted to some extent with the heterologous antigen in the ifa, the antigen with the higher titer correlated c ... | 1992 | 1328285 |
| clinical, epidemiologic, and virologic studies in four clusters of the chronic fatigue syndrome. | the purpose of this study is to provide a case definition of chronic fatigue syndrome in an outbreak occurring in the nevada-california region to evaluate candidate etiologic agents and observe the natural history of the illness. | 1992 | 1323246 |
| arboviral disease--united states, 1991. | during 1991, state and local health departments reported 122 cases of human arboviral encephalitis to cdc. more than half (69) of the cases resulted from outbreaks of st. louis encephalitis (sle) in arkansas and texas. in addition, an epizootic of eastern equine encephalitis (eee) extending from the atlantic and gulf coasts into the upper midwest caused sporadic human cases and a substantial loss of livestock. this report summarizes the reported cases of arboviral encephalitis in the united stat ... | 1992 | 1321947 |
| seroepidemiology of viral infections among intravenous drug users in northern california. | intravenous drug users are frequently exposed to parenterally transmitted viral infections, and these infections can spread to the general population through sexual activity. we investigated the prevalence of serologic markers for human immunodeficiency virus type 1 (hiv-1), human t-cell lymphotropic virus type i/ii (htlv-i/ii), hepatitis b virus (hbv), and hepatitis c virus (hcv) in intravenous drug users and their sexual contacts. of 585 drug users from northern california tested for these ser ... | 1992 | 1310362 |
| hiv prevention and the two faces of partner notification. | in the cases of medical patients with sexually transmitted diseases (particularly those with the human immunodeficiency virus), two distinct approaches exist to notifying sexual and/or needle-sharing partners of possible risk. each approach has its own history (including unique practical problems of implementation) and provokes its own ethical dilemmas. the first approach--the moral "duty to warn"--arose out of clinical situations in which a physician knew the identity of a person deemed to be a ... | 1992 | 1304728 |
| epidemiology of influenza in the elderly: evidence of virus recycling. | during the hong kong influenza epidemic of 1968-1969 the attack rate among persons born prior to 1890 was about one-third the rate among persons born after 1899. during an asian influenza epidemic in the same community two years earlier there was no apparent age effect. most persons born before 1890 had detectable pre-epidemic antibody against a/hong kong/68 whereas most persons born after 1899 had no detectable pre-epidemic antibody. the lower attack rate in the older age group is consistent wi ... | 1976 | 1251831 |
| a code of ethics for a community mental health program. | the orange county department of mental health developed a code of ethics to give its variety of employees a single set of standards for patient care and professional behavior in a community mental health program. the need for the code grew from problems of role definition and interdisciplinary collaboration that repeatedly arose during the program's development. general principles for the code were extracted from various professional codes, from issues arising in the day-to-day workings of the p ... | 1976 | 1245312 |
| [computerized patient-monitoring in the o.r (author's transl)]. | the routinely performed data-aquisition and its analysis by means of a computerized patient-monitoring-system will reduce the repetitive and often monotonous task of data collection accompanied by accuracy and objectivity as much as possible. another and equally important point for the anesthesiologists is to remove some of the pencil-and-paper burden, reduce the possibilities of human errors in reading instruments and note-taking and the rapid retrieval of monitored and stored data for the purp ... | 1975 | 1233480 |

| the bcg for measuring cardiac output in a california gray whale. | resting cardiac output can be predicted reasonably accurately from body mass in man and other mammals. we measured the stroke volume of a 4,500-kg whale and found that iberall's formula holds true even when body mass is very large. in addition, the bcg acceleration trace and cardiac indices were remarkably similar to those of 20-gram and 70-kg mammals, mouse and man. | 1976 | 985341 |
| the allergic theory of radiocontrast agent toxicity: demonstration of antibody activity in sera of patients suffering major radiocontrast agent reactions. | an allergic, immunologic mechanism for certain adverse reactions to radiocontrast agents has been postulated on the basis of clinical and theoretical considerations. one obstacle to the acceptance of this allergic theory has been the inability to demonstrate significant antibodies with specificity for these agents. in our studies, rabbits were immunized with 4 analogues of radiocontrast agents which induced igg or ige antibodies specific for the contrast media analogues. then, to determine if an ... | 1976 | 977260 |
