Hepatitis support groups: meeting the information and support needs of hepatitis patients.

An estimated 5 million Americans are chronically infected with hepatitis B or C. They face socially and clinically significant reductions in mental and physical health. Improved coping and compliance with clinical therapies and harm-reducing behaviors can improve quality of life and, potentially, treatment outcomes. Motivation to join, participation, use, and usefulness of online and in-person hepatitis support groups was examined through observation and survey of group members and group leaders. Members joined primarily to get information particularly about treatments, diet, and treatment side effects. They also joined to get support. All received support that was often hard to get elsewhere. Healthcare providers were generally the most used source of information, yet support groups were the most useful source of information. Members used the information and support obtained to make treatment and lifestyle changes such as initiating or ceasing treatment, eliminating alcohol consumption, increasing openness with family and friends, and discussing side effects with healthcare providers. Providers caring for hepatitis patients should consider recommending support groups to their patients and also participate in the groups to ensure that valid and reliable information is provided.

Practice parameter: treatment of postherpetic neuralgia: an evidence-based report of the Quality Standards Subcommittee of the American Academy of Neurology.

A systematic review of the literature on postherpetic neuralgia was performed. The authors identified studies using the National Library of Medicine's Medline database and Cochrane Library database. The authors determined absolute reduction rate, number needed to treat (NNT), 95% CI for NNT, and number needed to harm (NNH) for successful therapies of postherpetic neuralgia. Tricyclic antidepressants, gabapentin, pregabalin, opioids, and lidocaine patch were found to be effective in reducing the pain of postherpetic neuralgia.

Preventive health care, 2000 update: prevention of child maltreatment.

OBJECTIVES: To update the 1993 report from the Canadian Task Force on the Periodic Health Examination (now the Canadian Task Force on Preventive Health Care) by reviewing the evidence for the effectiveness of interventions aimed at preventing child maltreatment described in the scientific literature over the past 6 years. OPTIONS: Screening: a variety of techniques including assessment of risk indicators. PREVENTION: programs including home visitation; comprehensive health care programs; parent education and support, combined services and programs aimed specifically at preventing sexual abuse. OUTCOMES: Occurrence of one or more of the subcategories of physical abuse, sexual abuse, neglect and emotional abuse in childhood. EVIDENCE: MEDLINE, PSYCINFO, ERIC and several other databases were searched, experts were consulted, and published recommendations were reviewed. Original research articles and overviews that examined screening for or prevention of child maltreatment were included in the update. No meta-analysis was performed because the range of manoeuvres precluded comparability. BENEFITS, HARMS AND COSTS: Because of the high false-positive rates of screening tests for child maltreatment and the potential for mislabelling people as potential child abusers, the possible harms associated with these screening manoeuvres outweigh the benefits. Two randomized controlled trials showed a reduction in the incidence of childhood maltreatment or outcomes related to physical abuse and neglect among first-time disadvantaged mothers and their infants who received a program of home visitation by nurses in the perinatal period extending through infancy. It is expected that a reduction in incidence of child maltreatment and other outcomes will lead to substantial government savings. Evidence remains inconclusive on the effectiveness of a comprehensive health care program, a parent education and support program, or a combination of services in preventing child maltreatment. Education programs designed to teach children prevention strategies to avoid sexual abuse show increased knowledge and skills but not necessarily reduced abuse. VALUES: The systematic review and critical appraisal of the evidence were conducted according to the evidence-based methodology of the Canadian Task Force on Preventive Health Care. RECOMMENDATIONS: There is further evidence of fair quality to exclude screening procedures aimed at identifying individuals at risk of experiencing or committing child maltreatment (grade D recommendation). There is good evidence to continue recommending a program of home visitation for disadvantaged families during the perinatal period extending through infancy to prevent child abuse and neglect (grade A recommendation). The target group for this program is first-time mothers with one or more of the following characteristics: age less than 19 years, single parent status and low socioeconomic status. The strongest evidence is for an intensive program of home visitation delivered by nurses beginning prenatally and extending until the child's second birthday. There is insufficient evidence to recommend a comprehensive health care program (grade C recommendation), a parent education and support program (grade C recommendation) or a combination of home-based services (grade C recommendation) as a strategy for preventing child maltreatment, but these interventions may be recommended for other reasons. There is insufficient evidence to recommend education programs for the prevention of sexual abuse (grade C recommendation); whether such programs reduce the incidence of sexual abuse has not been established. VALIDATION: The members of the Canadian Task Force on Preventive Health Care reviewed the findings of this analysis through an iterative process. The task force sent the final review and recommendations to selected external expert reviewers, and their feedback was incorporated. SPONSORS: The Canadian Task Force on Preventive Health Care is funded through a partnership between the Provincial and Territorial Ministries of Health and Health Canada.

[Roller driver in the treatment of lower jaw deviation after resection].

The unilateral resection of the lower jaw results into displacement of the fragment preserved. Usually a driving device of the lower jaw is worked out for the treatment of the deviation that slides along the vestibular surfaces of the upper lateral teeth and restricts the articular disturbances. The authors task is to determine clinically the harmful forces of friction, proposing, at the same time, an original roller driver for their reduction.

A randomised placebo-controlled clinical trial of an acupressure device for weight loss.

OBJECTIVE: To provide a randomized placebo-controlled trial to determine the efficacy of an auricular acupressure device. DESIGN: Subjects were randomly assigned to either treatment or placebo. The treatment group received the acupressure device and were instructed to use the device in their dominant ear. The placebo group received an acupressure device for their wrist. Participants were followed for 12 weeks. SETTING: Outpatient core of the New York Obesity Research Center. SUBJECTS: 96 obese adult volunteers, 80 females and 16 males, between 19 and 70 years of age. MEASUREMENTS: Weight, body fat, and blood pressure measured every two weeks. RESULTS: All subjects combined lost, on average, 0.96 kg. There was no significant difference between the two groups on weight loss (mean wt loss = 1.28 [s.d. = 2.74] kg for treatment and 0.63 [s.d. = 3.26] kg for placebo) regardless of whether all subjects were examined or only the most compliant subjects were examined. Similarly, there were no significant differences between the two groups regarding fat loss or blood pressure reduction. CONCLUSION: The acupressure device appears to be a safe device (did not cause any harmful side effects). However, it did not promote significantly greater weight or fat loss, or declines in blood pressure than placebo.

Risks and benefits of long-term treatment with estrogens.

The goal of contemporary hormone replacement is to minimize net predictable lifetime risk; success therefore depends upon quantitative assessments of the net quality of life, of net morbidity and of net mortality. Estrogens ameliorate menopausal symptoms, maintain bone integrity, and produce endometrial cancer; these facts and their quantitative aspects can be stimulated. Other links are gradually becoming clear: estrogens increase biliary disease, but prevent heart disease, and, it now seems, stroke. Conventional wisdom to the contrary notwithstanding, a critical review suggests that breast cancer is probably increased in frequency by long-term estrogen use; the increase is modest as a risk factor but because breast cancer is a common disease, it is substantial in absolute terms. The addition of progestin seems attractive as a method of opposing undesirable estrogenic effects on the endometrium. In fact, there is reason for concern about the effect of an added progestin upon the risks from breast cancer, heart disease, and stroke; even the magnitude of the expected reduction in endometrial cancer may not be great when the hormone is administered sequentially. Using a simple deterministic model of post-menopausal life with hormone replacement, we have inserted available estimates of the regimen-specific relative risk for each outcome, and translated each net impact into common denominators of morbidity and mortality. While estrogens probably increase net morbidity, as measured by either the number of hospitalizations to be anticipated or by the more arbitrary measure of expected days of disability, these negative changes are mostly due to gallbladder disease and endometrial cancer, both largely treatable conditions. Largely because of protection against heart disease, estrogen replacement in modest dose is likely to reduce substantially the number of deaths to be expected in women treated through age 75 and even into more advanced age. Hormone replacement which includes systemic progestin supplementation has not been empirically tested; it may be beneficial, but it is at least as likely to be harmful. Either a modest increment in the number of additional breast cancers produced by estrogens, a modest reduction in the number of cardiac events prevented by estrogens, or a simultaneous minor shift in the same direction for each condition, would have the effect of shifting the net reduction in cumulative deaths into an increase in the number of deaths as a result of treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

Oxidation of fugitive methane in ground water linked to bacterial sulfate reduction.

When fugitive methane migrates upward along boreholes of oil and gas wells, it may migrate into shallow ground water or pass through overlying soil to the atmosphere. Prior to this study, there was little information on the fate of fugitive methane that migrates into ground water. In a field study near Lloydminster, Alberta, Canada, we found hydrogeochemical evidence that fugitive methane from an oil well migrated into a shallow aquifer but has been attenuated by dissimilatory bacterial sulfate reduction at low temperature ( approximately 5 degrees C) under anaerobic conditions. Evidence includes spatial and temporal trends in concentrations of methane and sulfate in ground water and associated trends in concentrations of bicarbonate and sulfide. Within 10 m of the oil well, sulfate concentrations were low, and sulfate was enriched in both 34S and 18O. Sulfate concentrations had a strong positive correlation with delta13C values of bicarbonate, and sulfide was depleted in 34S compared to sulfate. These data indicate that bacterial sulfate reduction occurred near the production well. Near the oil well, elevated concentrations of bicarbonate were observed, and the bicarbonate was depleted in 13C. Modeling indicates that the main source of this excess 13C-depleted bicarbonate is oxidized methane. In concert with the sulfate concentration and isotope data, these results support an interpretation that in situ bacterial oxidation of methane has occurred, linked to bacterial sulfate reduction. Bacterial sulfate reduction may play a major role in bioattenuation of fugitive natural gas in ground water in western Canada.

[The effects of midazolam on the general circulation, cerebral blood-flow and cerebral oxygen consumption in man (author's transl)].

The effects of midazolam, 0.2 mg/kg b.w., on cerebral blood flow, cerebral oxygen consumption and brain metabolism were studied in 8 patients scheduled for intracranial aneurysm surgery. All patients were anesthetized with fentanyl and N2O; arterial pCO2 and pO2 were maintained within the normal range by controlled ventilation. Midazolam produced minimal effects on the general circulation. Cerebral blood-flow decreased about 11% while cerebral oxygen consumption essentially remained unchanged. Cerebral perfusion pressure slightly decreased due to a reduction in mean aortic pressure. In three patients with elevated intracranial pressure midazolam decreased intracranial pressure significantly while there was no change in the other patients. It is concluded that midazolam is of no harm in patients with intracranial aneurysms. Furthermore this rapidly acting drug in addition to other measures might be of some benefit in patients with elevated intracranial pressure when immediate reduction of cerebral blood volume is desired.

Intravenous indomethacin for preventing mortality and morbidity in very low birth weight infants.

BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: Indomethacin is used to treat symptomatic patent ductus arteriosus and may prevent or limit intraventricular haemorrhage in the neonatal period. This review examines the effectiveness of prophylactic intravenous indomethacin in reducing the mortality and morbidity associated with these conditions in infants weighing less than 1750 grams at birth. SEARCH STRATEGY: A literature search from January 1980 to October 1994 was made in three computerised data bases: Medline; Embase; and the Oxford Database of Perinatal Trials. The search was updated in February 1997. SELECTION CRITERIA: Strict selection criteria were applied to clinical trials: the population had to be newborn infants of birth weight < 1751 grams; the intervention had to be prophylactic intravenous indomethacin; the trial had to be randomised and controlled; and at least one of several prespecified outcomes had to be reported in the results. DATA COLLECTION AND ANALYSIS: The methodological quality of each study was assessed using explicit criteria. Data on relevant outcome measures were extracted on two separate occasions and, where appropriate, the results of individual trials were combined using meta-analysis techniques to provide a pooled estimate of effect. MAIN RESULTS: There is a trend towards reduced neonatal mortality in infants receiving prophylactic indomethacin, pooled relative risk (RR) = 0. 85 [95% CI 0.66 to 1.09]. The incidence of symptomatic patent ductus arteriosus is significantly reduced in treated infants, pooled RR = 0.35 [0.26 to 0.47] but there is no evidence that treatment affects respiratory outcomes. Prophylactic indomethacin significantly reduces the incidence of Grade 3 and 4 intraventricular haemorrhage in treated infants, pooled RR = 0.60 [0.43 to 0.83]. There is no evidence to suggest prophylactic indomethacin is associated with any long term adverse effect although there is a trend in treated infants towards an increased incidence of necrotizing enterocolitis, and some evidence that treatment may transiently impair renal function. There is no evidence that haemostasis is disturbed. REVIEWER'S CONCLUSIONS: Prophylactic treatment with indomethacin has a number of immediate benefits, in particular a reduction in symptomatic patent ductus arteriosus and severe intraventricular haemorrhage. There is no evidence at present of long-term harm. Further trials are needed to assess more precisely the effects, both beneficial and harmful, on short and long-term outcomes.

Extended-duration prophylaxis against venous thromboembolism after total hip or knee replacement: a meta-analysis of the randomised trials.

BACKGROUND: The optimum duration of prophylaxis against venous thromboembolism after total hip or knee replacement is uncertain. Our primary objective was to establish the efficacy of extended-duration prophylaxis on symptomatic venous thromboembolic events. METHODS: We identified randomised trials comparing extended-duration prophylaxis using heparin or warfarin with placebo or untreated control in patients undergoing elective total hip or knee replacement by searching electronic databases (MEDLINE, EMBASE), references from retrieved articles, and abstracts from conference proceedings, and by contact with pharmaceutical companies and investigators. Two reviewers independently extracted data on study design, symptomatic and symptomless venographic venous thromboembolism, death, and bleeding outcomes. Results from individual trials were combined with the Mantel-Haenszel method. FINDINGS: Nine studies met our inclusion criteria (3999 patients), eight with low molecular weight heparin, and one with unfractionated heparin. Extended-duration prophylaxis for 30-42 days significantly reduced the frequency of symptomatic venous thromboembolism (1.3% vs 3.3%, OR 0.38; 95% CI 0.24-0.61, numbers needed to treat [NNT]=50), with no statistical evidence of heterogeneity (x(2) test, p=0.69). There was a greater risk reduction in patients undergoing hip replacement (1.4% vs 4.3%, 0.33; 0.19-0.56, 34) compared with knee replacement (1.0% vs 1.4%, 0.74; 0.26-2.15, 250). A significant reduction in symptomless venographic deep vein thrombosis was also observed (9.6% vs 19.6%, 0.48; 0.36-0.63, 10). There was no increase in major bleeding but extended-duration prophylaxis was associated with excess minor bleeding (3.7% vs 2.5%, 1.56; 1.08-2.26, numbers needed to harm [NNH]=83). INTERPRETATION: Among patients undergoing total hip or knee replacement, extended-duration prophylaxis significantly reduces the frequency of symptomatic venous thromboembolism. The reduction in risk is equivalent to about 20 symptomatic events per 1000 patients treated.

Treatment of hypertension in the 1990s. Optimizing the benefit of blood pressure reduction by minimizing risk factors for cardiovascular disease.

Due to the potency and multiple actions of available agents, current antihypertensive therapy can control blood pressure in virtually every patient with hypertension. In the past, physicians were primarily concerned with blood pressure reduction; the side effects of antihypertensive agents were a matter of lesser concern. Today, however, drugs can be selected for therapy on the basis of providing optimal antihypertensive efficacy and minimal harmful side effects. Furthermore, now that blood pressure can be effectively managed and the overall incidence of stroke has been reduced, perhaps the aim of therapy in patients with hypertension should include the reduction of coronary heart disease incidence. Three broad categories of antihypertensive agents are available: diuretics, antisympathetic agents, and vasodilators. Each class of drugs has its own pattern of action and produces optimal efficacy in identifiable patient populations, and each has a distinct side-effect profile. Knowledge of these variables and a scheme that can identify patients likely to benefit from a specific agent are paramount considerations in the treatment of hypertension.

Air versus oxygen for resuscitation of infants at birth.

BACKGROUND: 100% oxygen is the commonly recommended gas for the resuscitation of infants at birth. There is growing evidence from both animal and human studies that room air is as effective as 100% oxygen and that 100% oxygen may have adverse effects on breathing physiology and cerebral circulation. There is also the theoretical risk of tissue damage due to free oxygen radicals when 100% oxygen is given. The use of room air has, therefore, been suggested as a safer and possibly more effective alternative. OBJECTIVES: In newborn infants requiring resuscitation, does the use of room air reduce the incidence of death, neurological disability and short term morbidity when compared with the use of 100% oxygen? SEARCH STRATEGY: This included searches of the Oxford Database of Perinatal Trials, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2004) and MEDLINE PubMed 1966 to December 2003, and handsearches of reference lists of relevant articles and conference proceedings. SELECTION CRITERIA: All randomised and quasi-randomised studies comparing the use of room air or any other concentration of oxygen versus 100% oxygen in the resuscitation of infants at birth. DATA COLLECTION AND ANALYSIS: Three authors assessed the methodological quality of eligible trials and extracted data independently. When appropriate, meta-analysis was conducted to provide a pooled estimate of effect. For categorical data the relative risk (RR), risk difference (RD) and number needed to treat (NNT) with 95% confidence intervals (CI) were calculated. Continuous data were analysed using weighted mean difference (WMD). MAIN RESULTS: Five studies were identified which enrolled a total of 1302 infants. In two studies allocation was randomised and the caregivers were blinded to intervention group. In the other three studies, allocation was quasi-randomised and the caregivers were not blinded. Pooled analysis of the four trials reporting effect on death showed a significant reduction in the rate of death in the group resuscitated with room air [typical RR 0.71 (0.54, 0.94), typical RD -0.05 (-0.08, -0.01), NNT 20 (12, 100)]. There were no significant differences between the groups with respect to rates of grade 2 or 3 hypoxic ischaemic encephalopathy. One of the four trials reported a statistically significant difference in median 5 minute Apgar scores, favouring the group allocated to room air. However, the absolute difference between the medians was small and there were no significant differences in the median 10 minute Apgar scores in the three trials reporting this outcome. One trial followed up a selected subgroup of survivors to 18-24 months. There were no significant differences in rates of adverse neurodevelopmental outcomes including cerebral palsy and failure to achieve various milestones; however, the proportion of eligible patients seen was less than 70%. Analyses that were planned for this review, but not able to be carried out because of lack of published data, included a sub-analysis stratified by gestational age and assessments of the effect on bronchopulmonary dysplasia and retinopathy of prematurity. REVIEWERS' CONCLUSIONS: There is insufficient evidence at present on which to recommend a policy of using room air over 100% oxygen, or vice versa, for newborn resuscitation. A reduction in mortality has been seen in infants resuscitated with room air, and no evidence of harm has been demonstrated. However, the small number of identified studies and their methodologic limitations dictate caution in interpreting and applying these results. We note the use of back-up 100% oxygen in more than a quarter of infants randomised to room air. Therefore, on the basis of currently available evidence, if one chooses room air as the initial gas for resuscitation, supplementary oxygen should continue to be made available.

Temperament and character during the course of unipolar depression among inpatients.

Cloninger has developed a novel approach concerning relationships between psychopathological syndromes and personality by his biosocial theory. Increased levels of harm avoidance (HA) were consistently found in unipolar disorders. The present study was conducted to cross-validate, in part, previous findings that high harm avoidance (HA) persisted in the course of disorder and to explore the distinct role of character dimensions. One hundred and twenty-six inpatients with an unipolar depressive disorder and 126 healthy controls, strictly matched for age and gender have been included in the study. Our findings underline that higher harm avoidance among unipolar depressives compared to healthy controls persisted after treatment even if a significant reduction could be observed. Recurrent disorders and comorbidity with anxiety disorders seem to be related to a relatively immature character in terms of consistently lower scores for the character dimensions (e.g. self-directedness and cooperativeness) of the patients classified into these groups both at admission and at discharge compared with their healthy counterparts.

A method for separating bound versus unbound label during radioiodination.

An inexpensive, highly effective, and safe method for the removal of bound versus unbound label during radiolabeling of proteins is described. The technique employs the use of membrane ultrafiltration technology and returns in one step a highly reproducible product of quality superior to that attained by gel chromatography. Advantages of this technique are a reduction in the quantity of liquid and solid radioactive waste and a significant limitation of potentially harmful manipulation and exposure times.

Animal protection and toxicity testing regulations.

Safety testing illustrates a very real ethical dilemma between our moral obligations to protect humans and to protect animals from harm. The pragmatic approach to resolving this conflict is to pursue the 3 Rs of Replacement, Reduction and Refinement. Safety tests set out in regulation protocols often conflict with this ethic, being wasteful in numbers of animals used, having unnecessarily severe end-points and resulting in duplication. Suggestions for refinement of these tests are discussed. It is concluded that such refinement could lead to the generation of more meaningful data, thus improving both animal protection and human safety.

The renin angiotensin system as a therapeutic target to prevent diabetes and its complications.

The role of the RAAS in development and maintenance of blood pressure is well established. In addition, the deleterious effects of angiotensin II on the heart, vasculature, and kidneys have been clearly defined. There seems to be a close relationship between endothelial dysfunction, insulin resistance (a precursor to diabetes and coronary artery disease) and angiotensin II. The signaling pathways for insulin in the vascular wall interacts with the angiotensin signaling, giving rise to potential mechanisms for development of diabetes and resulting harmful effects. A large number of clinical trials using ACE inhibitors or ARBs have shown significant reduction in secondary endpoints in the development of new onset of diabetes. Ongoing prospective studies involving ARBs (eg, the Nateglinide and Valsartan Impaired Glucose Tolerance Outcomes Research trial) and ACE inhibitors (eg, the Diabetes Re-duction Assessment with Ramipril and Rosiglita-zone Medication trial) are testing the ability of certain agents to prevent type 2 diabetes. In the meantime, it is important to recognize insulin resistance and metabolic syndrome as entities that increase the risk for cardiovascular disease. In addition to lifestyle modifications, managing endothelial dysfunction and protecting the vasculature will help prevent diabetes and cardiovascular disease.

New therapies for alcohol problems: application to primary care.

Primary care physicians are frequently involved in the longitudinal care of patients with alcohol problems and in helping patients to decrease their alcohol consumption. Recent clinical trials provide evidence in support of new treatment strategies for these patients. Brief interventions have been used successfully to reduce alcohol consumption in patients with hazardous and harmful drinking. Twelve-step facilitation, cognitive behavioral, and motivational enhancement therapies have produced sustained drinking reductions in patients with alcohol dependence. Pharmacologic therapies, such as naltrexone and acamprosate, have been effective in decreasing alcohol consumption when provided along with psychosocial counseling in patients with alcohol dependence. The current review highlights the application of these new therapies to primary care physicians' efforts on behalf of their patients with alcohol problems.
