[The metaraminol provocation test in the diagnosis of familial Mediterranean fever].

Familial Mediterranean Fever (FMF) is a cyclic inflammatory disease of unknown pathogenesis and autosomal recessive inheritance. Diagnosis is notoriously difficult by the lack of specific signs or laboratory tests although early diagnosis is mandatory to avoid developmental delay or possibly fatal amyloidosis by treatment with colchicine. In adults, Metaraminol Provocative Test (MPT) has been described as specific and highly sensitive in the diagnoses of FMF. We tested 18 children, 9 of whom suffered from FMF. They were ill for 5 years and had been treated as in-patients for 3 months without improvement (median values). 5 of the children with FMF had a positive test results. 4 children with FMF were negative. All 9 children with other disorders were negative, too. During the course of diagnosis, they had been suspected of suffering from FMF. So, in childhood, MPT is specific for FMF but does not identify all children with FMF. However, a positive MPT may be a great help in diagnosing FMF.

Influence of trauma system implementation on process of care delivered to seriously injured patients in rural trauma centers.

BACKGROUND: Statewide trauma systems are implemented by health care policy makers whose intent is to improve the process of care delivered to seriously injured patients. In Oregon, Advanced Trauma Life Support (ATLS) training was mandated for all physicians employed in the emergency department of trauma centers. The purpose of this study was to test the hypothesis that mandatory ATLS training favorably influenced processes of care. METHODS: Seriously injured patients treated at 9 rural Level 3 and Level 4 hospitals were studied before (PRE) and after (POST) implementation of Oregon's trauma system. The processes of care evaluated on the basis of chart review were 20 diagnostic and therapeutic interventions advocated in the ATLS course. A cumulative process score (CPS) between 0 and 1 was assigned on the basis of the processes of care delivered. A CPS of 1 indicated optimal process of care. RESULTS: Mean CPS for 506 PRE period patients (0.44 +/- 0.27) was significantly lower than the mean CPS for 512 POST period patients (0.57 +/- 0.27) with an unpaired t test (P <.001). For the subgroup with injury severity score of 16 to 34, the mean CPS of survivors (0.67 +/- 0.19) was significantly higher than the mean CPS of decedents (0.57 +/- 0.25). CONCLUSIONS: Process of care for seriously injured patients improved after categorization of rural trauma centers in Oregon. Evidence shows improved process of care may have benefitted patients with serious but survivable injuries. Measurement of process of care is an alternative to mortality analysis as an indication of the quality of care.

HIV prevalence in pregnant women in Europe: differences in assessment methods and prevalence levels across countries.

OBJECTIVE: To describe methods used to assess HIV prevalence and to assess prevalence levels and time trends among pregnant women in various European countries. METHODS: We used the European HIV Prevalence Database to examine annual HIV prevalence data in pregnant women for the years 1990 to 1996 (20 countries). RESULTS: In Western Europe, prevalences were generally obtained through unlinked anonymous surveys, whereas in most Central, and Eastern European countries, they were based on testing programs (voluntary or mandatory). Prevalences (per 10,000) were highest (i.e., 10-30/10,000) in large western urban areas including Amsterdam, Barcelona, London, Milan, Paris, and Rome; between 1 and 2 in Scandinavian countries; and down to 0.5/10,000 in Central and Eastern European countries (except Ukraine, 1996: 5/10,000). Prevalences decreased in Rome, whereas they increased in London, the Czech Republic, and since 1995 in Russia and Ukraine; elsewhere, no time trends were detected. CONCLUSIONS: Methodologic differences and potential biases should be considered when comparing these data. HIV prevalence in pregnant women is useful for monitoring the AIDS epidemic and for assessing and improving prevention. Efforts should be made to offer voluntary counseling and testing to women at risk for HIV and provide treatment to those who are infected.

Ebola (subtype Reston) virus among quarantined nonhuman primates recently imported from the Philippines to the United States.

In April 1996, laboratory testing of imported nonhuman primates (as mandated by quarantine regulations) identified 2 cynomolgus macaques (Macaca fascicularis) infected with Ebola (subtype Reston) virus in a US-registered quarantine facility. The animals were part of a shipment of 100 nonhuman primates recently imported from the Philippines. Two additional infected animals, who were thought to be in the incubation phase, were identified among the remaining 48 animals in the affected quarantine room. The other 50 macaques, who had been held in a separate isolation room, remained asymptomatic, and none of these animals seroconverted during an extended quarantine period. Due to the rigorous routine safety precautions, the facility personnel had no unprotected exposures and remained asymptomatic, and no one seroconverted. The mandatory quarantine and laboratory testing requirements, put in place after the original Reston outbreak in 1989-1990, were effective for detecting and containing Ebola virus infection in newly imported nonhuman primates and minimizing potential human transmission.

Barriers to interlock implementation.

This commentary reviews current and past vehicle interlock programs for impaired driving offenders with a focus on the challenges that courts and motor vehicle departments face in attempting to implement mandatory programs as required by current federal legislation. There are few offenders in interlock programs compared to the large number of impaired drivers arrested each year. This suggests that, to increase participation, courts will have to threaten more severe sanctions for those offenders who reject interlock programs. A combination of electronic house arrest with interlock programs is suggested as a method of maximizing interlock use.

Special Supplemental Nutrition Program for Women, Infants, and Children (WIC): bloodwork requirements. Food and Nutrition Service, USDA. Final rule.

This final rule amends regulations governing the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) to allow State agencies the option to defer the collection of blood test data for up to 90 days after the date of certification, so long as the applicant is determined to have at least one qualifying nutrition risk factor at the time of certification. In addition, this final rule will expand the current regulatory standard of the maximum age of blood test data used to assess nutritional risk for WIC certification. Although blood tests may no longer be a mandatory part of each WIC applicant's certification intake process, such tests are still required for the purposes of assessing nutritional status, nutrition surveillance, providing nutrition education, further tailoring food packages to meet nutritional needs, and referring to appropriate health and social services in the community.

[On-site testing for drug abuse in urine].

BACKGROUND: There is an increasing interest in on-site testing for drugs of abuse. METHODS: Based upon our own experience and published literature, we have reviewed advantages and disadvantages of such tests. On-site testing is also evaluated in relation to the recommendations for urinary testing of drugs of abuse from the Norwegian Health Authorities. RESULTS: The most significant advantage with on-site testing is provision of rapid results, usually within 5-10 minutes. Disadvantages are the risks of false positive and false negative results, the fact that numerous drugs cannot be tested for, and the limited possibilities to detect manipulation. According to Norwegian regulations, on-site testing can be used for medical purposes, but cannot be used as the only method if a positive result may cause sanctions such as e.g. exclusion from school, job dismissal or loss of parental rights. There are also special requirements for the organization of such testing. INTERPRETATION: Before starting on-site testing for drugs of abuse, it should be considered if such testing is allowed or discouraged in the specific case. It is mandatory to know how the specific test works and to have routines for follow-up of positive test results.

Platelet function testing in apheresis products: flow cytometric, resonance thrombographic (RTG) and rotational thrombelastographic (roTEG) analyses.

During storage of platelet concentrates, quality control of the units is mandatory. This includes the important testing of the hemostatic function of platelets. So far, mostly platelet aggregation analyses have been performed. In this study, new approaches were tested to evaluate the applicability of modern techniques for quality monitoring. Plateletpheresis was performed with two different cell separators (AMICUS cell separator, Fenwal, Baxter Healthcare, Deerfield, USA; COBE Spectra, COBE BCT, Lakewood, USA). In each procedure split products (n = 22) were prepared and stored for 1-2 days (n = 22) or 3 5 days (n = 22). Platelet hemostatic capacity was tested by applying flow cytometry. platelet aggregation (platelet-rich-plasma [PRP]+agonist), resonance thrombography (RTG; PRP, no agonist) and rotational thrombelastography (roTEG; PRP+agonist). Flow cytometric analyses did not reveal significant changes in structural (CD41a. CD42b) or activation-dependent antigens (CD62p, CD63, LIBS, RIBS). Also, differences in the data from the flow cytometric reactivity tests were not significant between the two groups. In platelet aggregation assays, shape change (p = 0.8), maximum aggregation (p = 0.4), and maximum gradient (p = 0.8) did not show significant differences between the two groups. In the RTG test, differences between r-time (reaction time; p = 0.4), and f-time (clot formation time [fibrin influence]; p = 0.3), and in roTEG r-time (coagulation time; p = 0.1) and k-time (clot formation time; p = 1.0) were not significant. P-time (clot formation time [platelet influence]) and M (maximum amplitude) in RTG, and k-time and MA (maximum amplitude) in roTEG showed a slight decrease in platelet function (p < or = 0.05). We conclude that platelet function is well maintained during storage. This is reflected by the results of immunological and platelet function assays. Rotational thrombelastography (in the case of PRP) and especially resonance thrombography represent promising methods for quality control of platelet concentrates and rapidly provide information about the status of platelet function and the whole clotting process.

Employee testing raises workplace privacy issues.

With increasing frequency, employers are considering mandatory screening for substance abuse and AIDS. These tests are focusing attention on an area of growing concern for hospitals--employees' right to privacy in the workplace--and prompting trustees to define an institutional philosophy for their hospital.

Attitudes of persons at risk for Huntington disease toward predictive testing.

Attitudes of 69 persons at risk for Huntington disease (HD) were obtained by means of semistructured interviews and questionnaires. About 79% of the individuals said that they would use a presymptomatic predictive test if it were available. All believed that the test should be made available even though there was no cure for HD. Nearly 2/3 of subjects would use the test for prenatal diagnosis, and of these 71% would terminate a pregnancy if the fetus was found to carry the HD gene. Most subjects believed that pretest counseling should be mandatory and many said that testing should be withheld from persons who were psychologically unstable or were threatening self-harm. The data suggest that about 2-6% of persons at risk for HD may have severe psychiatric or suicidal responses to a positive outcome of predictive testing. This underscores the need for adequate pretest counseling and the availability of professional and community resources to deal with the impact of predictive testing on individuals and their relatives.

HIV infection and zidovudine use in childbearing women.

OBJECTIVE: The risk of vertical HIV transmission from mother to child has been shown to be markedly decreased through HIV education, counseling, testing, and zidovudine (ZDV) use. The US Public Health Service published guidelines in 1994 for the use of ZDV on the basis of results of the AIDS Clinical Trials Group Protocol, a multicenter clinical trial of ZDV. The Public Health Service followed these guidelines with recommendations for routine HIV counseling and testing with informed consent for all pregnant women. New Jersey adopted these guidelines as the standard of care and created a program implementing the standard in all hospitals with maternity units. The purpose of this report was to study the trends in the rate of HIV infection in childbearing women over the past decade and to follow patterns of use of ZDV in the HIV-positive women, as a marker for the success of New Jersey's policy and program to reduce mother-to-child transmission. METHODS: Since 1988 in New Jersey, blood from heel-stick filter papers has been tested for the presence of HIV antibody through anonymous, unlinked surveys. Excess blood from screening for inborn errors of metabolism for all infants who were born in the state from July through September of each year was tested using a Food and Drug Administration-approved HIV-1 and Western blot test. Age, race, and ethnicity were recorded, as well as the results from the HIV-1 and Western blot tests. Since 1994, specimens confirmed to be HIV-1 positive by Western blot test were tested for the presence of ZDV, and the results were recorded. RESULTS: The number of New Jersey women included in the study for the period 1990 through 2002 numbered 372305. The percentage of childbearing women who tested positive for HIV declined by 55% during the period, although the declines were not uniform in all subgroups. In the early 1990s, women who were <30 years old had higher infection rates than older women, but this has not been a consistent pattern during the period. Younger women again had a higher rate in 2002. When HIV-positive rates are examined by 5-year age groups, the declines are dramatic for younger women. The rate per 100 women 20 through 24 years decreased from 0.46 per 100 tested women in 1990 to 0.29 in 2002 and for women 25 through 29 years from 0.51 per 100 in 1990 to 0.25 in 2002. The rate for women 30 through 34 years of age declined from 0.54 in 1990 to 0.13 in 2002. During the same time period, the rate per 100 tested women 35 though 39 years of age increased from 0.23 to 0.33. Black non-Hispanic women who give birth to live infants have the highest HIV-positive rates, followed by Hispanic women and white non-Hispanic women. In 2002, this rate was 0.74 per 100 in black non-Hispanic women, 0.22 per 100 in Hispanic women, and 0.08 in white non-Hispanic women. Although major disparities continue, the infection rate in black non-Hispanic women demonstrated the greatest decrease during the period, followed by the decline among Hispanic women. The use of ZDV in HIV-positive women increased dramatically during the period, from 13.3% in 1994, when it was first tested in New Jersey, to an all-time high of 88.5% in 2002. CONCLUSIONS: Reducing perinatal HIV transmission is a priority for the New Jersey Department of Health and Senior Services. Reducing perinatal transmission can be accomplished by reducing the number of infants who are exposed perinatally or decreasing the percentage of exposed infants for whom transmission occurs or both. The decrease in prevalence of HIV-positive status in childbearing women is in opposition to an overall increasing trend in prevalence rates. This decrease is thought to be attributable in part to the positive impact of numerous education and prevention programs but may also be the result of a voluntary decision on the part of HIV-infected women not to become pregnant or not to carry to term. In addition, the cohort of women who became infected in the early years of the epidemic may be aging out of their childbearing years, may have more advanced disease with a concomitant difficulty with fertility and carrying to term, or may have died. In New Jersey, a greater proportion of women with newly diagnosed HIV disease are past their childbearing years as compared with earlier years. Increased use of ZDV is thought to be attributable to several factors: dissemination of information to health care providers via continuing medical education activities; dissemination of information to the public, in particular to women; outreach via community-based organizations; and New Jersey Department of Health and Senior Service regulations and policies for mandatory counseling and voluntary testing of all pregnant women. A recent addition to New Jersey's comprehensive program to decrease perinatal transmission occurred in 2002 with dissemination to hospitals of the department's standard of care for women who present in labor with unknown HIV status. Physicians, nurses, and hospitals play vital roles in preventing vertical transmission of HIV by providing preconception and postconception counseling, testing with consent of pregnant women, and treatment for HIV-positive mothers, including administration of ZDV. This study not only provides an estimate of the prevalence of HIV infection in the population of childbearing women but also provides a means of examining the vertical transmission of HIV infection from mother to child. Continued research on this subpopulation as well as on other groups will provide additional knowledge to help in the overall goal of reducing HIV prevalence.

Survey of physician attitudes toward HIV testing in pregnant women in Ohio.

HIV infection among women of childbearing age is still increasing in the United States. In most states, HIV testing of women or neonates during pregnancy is not mandatory. The current study assessed HIV prenatal testing practices among obstetrician-gynecologists and primary care physicians listed in a regional physician referral data base in a predominantly rural region. Between December 2000 and March 2001 a 20-question survey was sent by mail to regional physicians in obstetrics/gynecology and primary care regarding physician practice demographics and prenatal HIV testing practices. Of 1116 surveys sent, 431 were returned (38.6% response). Only 42% of physicians offered universal HIV prenatal testing. Factors associated with universal testing (p < 0.5) included obstetrics/gynecology as the practice specialty (90%) physicians' age younger than 50 years, and a practice with predominantly Medicaid or African American patients. Further educational and public health initiatives may be needed to increase nonselective, universal HIV testing in pregnant women.

Addressing the public's concerns about human immunodeficiency virus transmission in health-care settings.

BACKGROUND: The 1990 report of a cluster of patients infected with the human immunodeficiency virus (HIV) associated with a Florida dentist with acquired immunodeficiency syndrome attracted considerable media coverage and legislative attention. A number of polls found that the public favored mandatory HIV-antibody testing of health-care workers. The Centers for Disease Control and Prevention, Atlanta, Ga, conducted a two-phase study to understand how public concerns regarding potential HIV transmission in health-care settings can be addressed by the medical and public health communities. METHODS: Sixteen focus group discussions in nine US cities were conducted to explore the public's perceptions, concerns, and behavioral responses regarding HIV transmission in health-care settings. Using this information, a questionnaire was developed and administered to a nationwide probability telephone sample of 1150 adults. RESULTS: Concern about contracting HIV in health-care settings was highest for emergency department treatment and lowest for treatment by a personal physician. Two factors directly related to patient care, ie, the health-care professional's willingness to discuss acquired immunodeficiency syndrome and the presence of acquired immunodeficiency syndrome educational materials in the waiting room, were considered useful factors for determining potential risk of transmission of HIV in a health-care setting. CONCLUSIONS: Public concern about the potential for HIV transmission in health-care settings remains high. Active steps on the part of health-care professionals, such as providing educational materials and initiating discussions about infection control procedures and about HIV and acquired immunodeficiency syndrome, could likely have positive effects in terms of alleviating these concerns.

Postoperative irradiation treatment and bioresorbable implants in orthopaedic surgery: an experimental in vitro study.

The influence of applied radiation on the degradation of a polyglycolide (PGA) test specimen was studied in vitro. There was no significant difference in the time-dependent degradation behaviour between the irradiated test specimen and controls. Mandatory irradiation of an operation site following surgery therefore does not contradict the employment of bioresorbable implants in orthopaedic surgery.

Measuring residual solvents in pharmaceutical samples using fast gas chromatography techniques.

Residual process solvents in pharmaceutical samples are monitored using gas chromatography (GC) with either flame ionization detection (FID) or mass spectrometry. Based on good manufacturing practices, measuring residual solvents is mandatory for the release testing of all active pharmaceutical ingredients and is routinely performed on samples of process intermediates. General GC methods have been developed to monitor solvents routinely used in the drug synthesis process. It is now possible to take advantage of GC equipment with faster temperature ramping capabilities, in combination with shorter capillary GC columns, to achieve a considerable gain in efficiency and a reduction in analysis turnaround time. In this paper, the development and implementation of fast GC methods for residual solvents testing will be discussed. Continued efforts to improve the efficiency of gas chromatography using existing technologies such as, the ThermoOrion Flash GC will also be discussed.

Syncope in the pediatric patient. The cardiologist's perspective.

The evaluation of syncopal children or adolescents relies heavily on a thorough, detailed history and physical examination. All syncope associated with exercise or exertion must be considered dangerous. The ECG is mandatory, but other laboratory tests are generally of limited value unless guided by pertinent positives or negatives in the history and physical examination. The ECG allows screening for dysrhythmias, such as Wolff-Parkinson-White syndrome, heart block, and long QT syndrome, as well as hypertrophic cardiomyopathies and myocarditis. Tilt table testing can be useful in selecting therapy by demonstrating the physiologic response leading to syncope in an individual patient. The most common type of syncope in otherwise healthy children and adolescents is neurocardiogenic or vasodepressor syncope, which is a benign and transient condition. Because syncope can be a predictor of sudden cardiac death, it must be taken seriously, and appropriate screening must be performed.

Eugenics and genetic testing.

Pressures to lower health-care costs remain an important stimulus to eugenic approaches. Prenatal diagnosis followed by abortion of affected fetuses has replaced sterilization as the major eugenic technique. Voluntary acceptance has replaced coercion, but subtle pressures undermine personal autonomy. The failure of the old eugenics to accurately predict who will have affected offspring virtually disappears when prenatal diagnosis is used to predict Mendelian disorders. However, when prenatal diagnosis is used to detect inherited susceptibilities to adult-onset, common, complex disorders, considerable uncertainty is inherent in the prediction. Intolerance and the resurgence of genetic determinism are current pressures for a eugenic approach. The increasing use of carrier screening (to identify those at risk of having affected offspring) and of prenatal diagnosis could itself generate intolerance for those who refuse the procedures. Genetic determinism deflects society from social action that would reduce the burden of disease far more than even the maximum use of eugenics.
