Characteristics of heart rate variability in alcohol-dependent subjects and nondependent chronic alcohol users.

Heart rate variability (HRV) is an objective and sensitive measure of integrated physiological functioning reflective of heart rhythm responsivity to internal and external demands. Reduced HRV is associated with vulnerability to stress and deterioration of medical and/or psychiatric conditions, while increased HRV is associated with a favorable treatment response and recovery from various medical and/or psychiatric conditions. Our previous review found that acute alcohol consumption caused decreased parasympathetic and increased sympathetic HRV effects in both nonalcoholic and chronic alcohol users. This review investigates the effects of chronic alcohol consumption on HRV in alcohol-dependent subjects and nondependent users. MEDLINE, Scopus, and PubMed were searched for human experimental and clinical trials that measured the effects of chronic alcohol use on HRV. Only publications that included a description of their study designs and clearly stated methodologies for data collections, and outcome measures were reviewed. We have reviewed a total of 24 articles. In nondependent users, low dose (approximating the recommended daily amount of 1 standard drink in women and 2 in men) use is associated with increased HRV parameters compared to those who drink less frequently or abstain altogether. A further increase in consumption is associated with decreased HRV compared to both abstainers and more moderate drinkers. HRV changes during withdrawal generally follow the same negative direction but are more complex and less understood. In dependent subjects, an improvement in HRV was seen following abstinence but remained reduced compared to nonalcoholic controls. This review demonstrates that HRV changes associated with chronic use follow a J-shaped curve. It supports recommendations that limit daily alcohol intake to no more than 2 drinks for men and 1 drink for women. Future studies should investigate HRV as a biomarker of alcoholism development and treatment response as well as the physiological basis for alcohol effects on HRV.

Changes in heart rate variability associated with acute alcohol consumption: current knowledge and implications for practice and research.

Alcohol consumption is associated with a broad array of physiologic and behavioral effects including changes in heart rate. However, the physiologic mechanisms of alcohol effects and the reasons for individual differences in the cardiac response remain unknown. Measuring changes in resting heart rate (measured as beats/min) has not been found to be as sensitive to alcohol's effects as changes in heart rate variability (HRV). HRV is defined as fluctuations in interbeat interval length which reflect the heart's response to extracardiac factors that affect heart rate. HRV allows simultaneous assessment of both sympathetic and parasympathetic activity and the interplay between them. Increased HRV has been associated with exercise and aerobic fitness, while decreased HRV has been associated with aging, chronic stress, and a wide variety of medical and psychiatric disorders. Decreased HRV has predictive value for mortality in general population samples and patients with myocardial infarction and used as an indicator of altered autonomic function. A significant inverse correlation was found between HRV and both the severity of depression and the duration of the depressive episode. HRV analysis provides insights into mechanisms of autonomic regulation and is extensively used to clarify relationships between depression and cardiovascular disease. This article will review the methodology of HRV measurements and contemporary knowledge about effects of acute alcohol consumption on HRV. Potential implications of this research include HRV response to alcohol that could serve as a marker for susceptibility to alcoholism. At present however there is almost no research data supporting this hypothesis.

Impact of dopamine agonists on compulsive behaviors: a case series of pramipexole-induced pathological gambling.

BACKGROUND: Dopamine agonists (DAs), long used in treating Parkinson's disease and effective in relieving symptoms of restless legs syndrome, have frequently been reported to induce problematic compulsive behaviors (e.g., obsessive gambling, hypersexuality) in individuals who had never had difficulties with such behaviors before. OBJECTIVE: The authors report two cases that add to a small-but-growing literature suggesting that these drugs be dispensed with appropriate caution. METHOD: The authors describe two patients seen in a psychiatric setting-one, after a suicide attempt, and one with depression-both resulting from intractable compulsive gambling. RESULTS: In both instances, control of gambling was achieved: in one, when pramipexole was discontinued, and in the other, after substitution of ropinirole and addition of spiritual and support-group approaches. DISCUSSION: DAs stimulate pathways that govern reward behavior, including pleasure and addiction. Other reward behaviors, such as eating and sexual activity, may also be affected by DAs. These cases demonstrate a clear temporal relationship between initiation and behavioral change; patients and their caregivers should be alerted to the possibility of such changes.

Differentiating suicide from life-ending acts and end-of-life decisions: a model based on chronic kidney disease and dialysis.

BACKGROUND: Technological advances continue to yield life-prolonging treatments that complicate the occurrence of death. Until recently, refusal to submit to recommended care was considered suicide. OBJECTIVE: Physicians must now decide how to respond to requests for hastened dying. METHOD: The authors propose a four-square grid distinguishing true suicide from behaviors such as treatment termination and lethal noncompliance. RESULTS: One axis characterizes whether actions hasten death. The other identifies how the patient's social and medical network collaborate in the decision-making process. CONCLUSION: Using chronic kidney disease to model intent and collaboration, treatment is framed within a paradigm that reflects both end-of-life decision-making complexities and contemporary conceptualizations of suicide.

The lifetime risk of suicide in schizophrenia: a reexamination.

BACKGROUND: The psychiatry literature routinely quotes a lifetime schizophrenia suicide prevalence of 10% based on 1 meta-analysis and 2 studies of chronic schizophrenics. OBJECTIVES: To build a methodology for extrapolating lifetime suicide prevalence estimates from published cohorts and to apply this approach to studies that meet inclusion criteria. DATA SOURCES: We began with a MEDLINE search (1966-present) for articles that observed cohorts of schizophrenic patients. Exhaustive bibliography searching of each identified article brought the total number of articles reviewed to 632. STUDY SELECTION: Studies included in the meta-analysis observed a cohort of schizophrenic patients for at least 2 years, with at least 90% follow-up, and reported suicides. Articles are excluded for systematic age bias (ie, adolescents). DATA EXTRACTION: Extracted data included sample size, number of deaths, number of suicides, percentage of follow-up, and diagnostic system used. Data were extracted independently by 2 of us, and differences were resolved by consensus after re-review. DATA SYNTHESIS: Studies were divided into 2 groups: 32 studies of schizophrenics enrolled at various illness points (25 578 subjects) and 29 studies of schizophrenics identified at either illness onset or first admission (22 598 subjects). Regression models of the intersection of proportionate mortality (the percentage of the dead who died by suicide) and case fatality (the percentage of the total sample who died by suicide) were used to calculate suicide risk in each group. The estimate of lifetime suicide prevalence in those observed from first admission or illness onset was 5.6% (95% confidence interval, 3.7%-8.5%). Mixed samples showed a rate of 1.8% (95% confidence interval, 1.4%-2.3%). Case fatality rates showed no significant differences when studies of patients diagnosed with the use of newer systems were compared with studies of patients diagnosed under older criteria. CONCLUSION: This study estimates that 4.9% of schizophrenics will commit suicide during their lifetimes, usually near illness onset.

Benzodiazepine Use in Older Adults: Dangers, Management, and Alternative Therapies.

Several major medical and psychiatric organizations, including the American Geriatrics Society, advise against using benzodiazepines or nonbenzodiazepine hypnotics in older adults. Despite these recommendations, benzodiazepines continue to be massively prescribed to a group with the highest risk of serious adverse effects from these medications. This article summarizes legitimate reasons for prescribing benzodiazepines in the elderly, serious associated risks of prescribing them, particularly when not indicated, barriers physicians encounter in changing their prescription patterns, and evidence-based strategies on how to discontinue benzodiazepines in older patients. Although more research is needed, we propose several alternatives for treating insomnia and anxiety in older adults in primary care settings. These include nonpharmacological approaches such as sleep restriction-sleep compression therapy and cognitive behavioral therapy for anxiety or insomnia, and as well as alternative pharmacological agents.

The use of electroencephalography in psychiatry of the medically ill.

The psychiatrist considering recommending an EEG should look for acute changes in the history or examination suggestive of an organic cause. If he or she judges that the EEG will help to clarify or confirm the diagnostic impression already formulated, it is worth considering whether adding provocative maneuvers could increase the yield. The authors cannot overemphasize the importance of using the EEG in correlation to further inform old-fashioned clinical detective work already in process, particularly when the EEG could rule out a potential organic contributor to a psychiatric phenotype. For routine screening without an elevated index of suspicion or for thoughtless "fishing expeditions," EEG results will surely disappoint.

Hospitalized patients and alcohol: who is being missed?

Research and clinical experience have shown that alcohol use disorders are neither sufficiently identified nor addressed in hospitalized patients. This study sought to quantify and localize these missed opportunities. The setting was an urban medical center with a Level 1 trauma designation. The only eligibility requirement was a Blood Alcohol Level (BAL) greater than 300 ng/dl upon hospital admission, a "nonsubtle" value more than three times the legal intoxication limit. Charts [58] were retrospectively reviewed for treating service (medical, trauma services, or psychiatric) and evidence of psychological signs or behavioral symptoms of withdrawal. Also assessed were the presence or absence of withdrawal monitoring, withdrawal prophylaxis orders, inpatient addictions consultation, and referral for addictions aftercare. Numerous patients with admission BALs >300 failed to be identified as needing assessment for alcohol-related disorders. Patients admitted to medical or psychiatric services were significantly more likely to be diagnosed than those on trauma services (P =.02). Patients on medical or psychiatric services were also more likely to be assessed for withdrawal and referred for after-care (P <.0001) than those cared for on trauma services. The delivery of care for alcohol-related disorders was deficient, particularly for patients with traumatic injuries, even among patients severely intoxicated at admission. Failure to identify such patients represented a missed opportunity to address this vital contributor to trauma. It is suggested that both the origins of this shortfall and its resolution depend not just upon trauma providers but upon the entire medical system.

TRAM flap breast reconstruction: tumescent technique reduces blood loss and transfusion requirement.

The tumescent technique has been shown to be efficacious in reducing both operative and postoperative bleeding without significant deleterious side effects in suction lipectomy. In this study, the effects of the tumescent technique on postoperative complications in transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction are investigated. All women who underwent a TRAM flap breast reconstruction by the senior author (J.B.) at the Emory Clinic during the years 1990 to 1996 were pooled (n = 386). Any woman who had a preincision infiltration of 0.25% epinephrine-containing saline solution (>200 cc) around the donor site was included in the tumescent group (n = 59). Medical records were reviewed, and rates of partial flap loss, fat necrosis (> or =10 percent flap volume), flap full-thickness skin loss, donor-site complication (skin loss, hernia, or infection), and blood transfusion were determined. Group rates were compared. The infiltrated group had a significantly lower transfusion rate as compared with the control group (0.34 units versus 1.32 units, p < 0.001). The rates of partial flap loss and fat necrosis were less in the tumescent group, but not significantly (0 percent versus 4 percent, p = 0.232; and 1.7 percent versus 10.4 percent, p = 0.058). There were no significant differences in the incidence of full-thickness skin loss or donor-site complications. Donor-site infiltration before incision with a 0.25% epinephrine-containing saline solution significantly reduced the transfusion requirement in TRAM flap breast reconstruction patients without adversely affecting either breast mound or abdominal donor-site complication rates.

The role of reduction mammaplasty in reconstructing partial mastectomy defects.

The management of breast tumors in women with macromastia can be challenging. Reconstructive options are limited and breast conservation therapy is often not indicated or results in poor cosmetic outcomes. The purpose of this report was to present a series of women with macromastia who underwent simultaneous reconstruction of a partial mastectomy defect with bilateral reduction mammaplasty. A retrospective review was performed and included all women who underwent partial mastectomy with simultaneous reduction mammaplasty. Data points included patient demographics, preoperative assessment, operative intervention, adjuvant treatment, and outcomes. Twenty women were included in the series (mean age, 43 years; range, 11 to 72 years) with an average body mass index of 32.6 (range, 24.9 to 44.1). Tissue diagnosis was ductal carcinoma (n = 8), ductal carcinoma in situ (n = 6), fibroadenoma (n = 4), and benign breast tissue (n = 2). The various reduction mammaplasty techniques were documented with regard to tumor size and location. The superior medial and inferior pedicles seemed to be the most versatile techniques. One patient required completion mastectomy with autologous tissue reconstruction given positive margins. All patients were disease-free at follow-up (mean, 23 months) and postoperative cancer surveillance was not impaired by the combined procedures. The versatility of reduction mammaplasty allows this procedure to be performed in conjunction with partial mastectomy for any tumor location. Combining these procedures in patients with macromastia provides numerous therapeutic benefits at low cost, while reducing breast distortion and preserving symmetry.

Trends in unilateral breast reconstruction and management of the contralateral breast: the Emory experience.

Recent trends in breast reconstruction have transitioned toward the skin-sparing type of mastectomy and immediate reconstruction using autologous tissue. This study was designed to document trends in the management of patients with unilateral breast cancer and to determine how they influence management of the contralateral breast. All patients who underwent unilateral breast reconstruction at Emory University Hospitals from January of 1975 to December of 1999 were reviewed. The cohort was stratified by timing of reconstruction (immediate versus delayed), method of reconstruction, and mastectomy type (skin-sparing versus non-skin-sparing). The methods of reconstruction included implant, latissimus dorsi flap, and transverse rectus abdominis musculocutaneous (TRAM) flap. Contralateral procedures to achieve symmetry included augmentation, mastopexy, augmentation/mastopexy, and reduction. A total of 1394 patients were evaluated, including 689 delayed and 705 immediate reconstructions. Sixty-seven percent of delayed-reconstruction patients (462 of 689) had a symmetry procedure performed on the opposite breast, compared with 22 percent for the immediate-reconstruction patients (155 of 705) (p

Significance of intraabdominal compartment pressures following TRAM flap breast reconstruction and the correlation of results.

Abdominal wall closure after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction is often performed under considerable tension and may theoretically cause a component of abdominal compartment syndrome. This prospective study examined intraabdominal pressure after TRAM reconstruction and correlated the findings with clinical course and outcome. All patients who underwent pedicled TRAM flap breast reconstruction from November of 1999 to December of 2000 (n = 77) were included and compared with nonoperative controls (n = 24). Intraabdominal pressures were measured indirectly using the urinary catheter in the postanesthesia care unit on postoperative days 1 and 2. Outcome measures included vital signs, urinary output, net 24-degree fluid balance, and complications. The preoperative variables were age, body mass index, parity, and presence of an epidural. For statistical analysis, the TRAM patients were divided into three groups on the basis of type of closure (bipedicle, unipedicle, and mesh), which were compared by analysis of variance. A multivariate logistic regression was performed to identify risk factors for patients with intraabdominal pressures > or =20 mmHg who were thought to have a component of abdominal compartment syndrome. The incidence of complications was compared by chi-square, with statistical significance determined for p < 0.05. Average intraabdominal pressures were significantly higher in the bipedicled TRAM (14.1 mmHg) and unipedicle TRAM (9.9 mmHg) groups when compared with the mesh group (5 mmHg) and controls (3.7 mmHg; p < 0.001). Increased intraabdominal pressure was transient and peaked on postoperative day 1. Elevated pressure was associated with decreased urinary output, decreased net fluid balance, and increased respiratory rate. Patients with intraabdominal pressures > or =20 mmHg (n = 10) had a higher incidence of complications (60 percent) compared with patients who had pressures <20 mmHg (18 percent; p < 0.05). Elevated intraabdominal pressures were strongly associated with donor-site and general complications. Positive predictive factors for elevated pressure included body mass index and type of closure (bipedicled or bilateral). Multiple pregnancies seemed to have a protective effect.A transient component of abdominal compartment syndrome does exist after TRAM flap breast reconstruction. Bipedicle closure, nulliparous women, and increased body mass index were risk factors for elevated intraabdominal pressures. Tension-free mesh closure seemed to have a protective effect. Symptomatic trends and certain complications were associated with, and possibly explained by, an elevated intraabdominal pressure.

The Challenge of Empathy: A Pilot Study of the Use of Standardized Patients to Teach Introductory Psychopathology to Medical Students.

This pilot study compares standardized and actual psychiatric patients used to teach introductory psychopathology. In a blinded manner, students and psychiatric faculty interviewed both types of patients, using a small group format. Before and after the course, students and faculty completed a questionnaire about expectations and effectiveness. Students were divided in their opinions of standardized patients but generally preferred actual patients. Faculty were initially noncommittal, but after the course they strongly preferred actual patients. Although standardized patients offer some advantages over actual patients, limitations included difficulty developing empathy. Standardized patients could potentially be trained to convey emotions realistically, but further study of this is needed.

Temporal competency in catatonia.

A catatonic patient without known relatives or advance directives faced possible death without electroconvulsive treatment (ECT). The authors describe using medication to restore capacity to permit the patient to give critical history and consent to potentially life-saving treatment. Even had a proxy been available, the jurisdiction in which he fell ill forbade substituted judgment for ECT, permitting only recipients themselves to consent. While emergent ECT was not specifically forbidden in this jurisdiction, a full curative course presumably could not have been administered without some form of consent. THus, the intervention prevented a treatment delay while the court was petitioned and also avoided having to insert a judge into the doctor-patient relationship. This case focuses on a specific condition, medication, and jurisdiction, but it outlines a general paradigm of pharmacologic intervention to restore temporary capacity. We encourage physicians to identify situations in which medication can create temporary "lucid intervals," thereby restoring patient autonomy and self-determination that would otherwise be lost to proxies or courts of law.

The pediatric surgeon-patient relationship.

Though technical aspects of surgical practice are commonly emphasized, communication is the most frequent "procedure" employed by surgeons. A good patient-physician relationship enhances the quality of surgical care by improving outcomes and patient and family satisfaction. There are general principles that can enhance communication with all children and families. Employing a developmentally sensitive approach that adjusts communication style based on a child's cognitive abilities and emotional concerns can further enhance the relationship with children of different ages. These communication skills can be learned and are improved by practice and self-reflection.

Do cheap internet drugs threaten the safety of the doctor-patient relationship?

During traditional office visits, trusted physicians give their patients careful and leisurely diagnostic attention, communicate sound and understandable clinical impressions and, more often than not, write prescriptions that can be filled at convenient neighborhood pharmacies. Or do they? In reality, harried doctors rush through appointments, leaving patients confused about prescriptions they cannot afford, either because their insurance plans do not cover the recommended medication or because they lack the cash to pay out of pocket for obscenely priced products. Internet pharmaceutical acquisition offers a cheap alternative. Or does it?

Do SSRIs cause suicide in children? The evidence is underwhelming.

After regulatory agencies in the United Kingdom and United States recommended severe restrictions on antidepressant use in children, many lessons were learned, although one was not that these drugs cause suicide. We learned that pharmaceutical companies selectively released data that reflected positively on their products and that combining suppressed and published data suggested that most of these medications had questionable efficacy. We also learned that the studies lacked uniformity both in which age groups constituted children and which behavior was considered suicidal. Several recent, large nonindustry studies indicated that rates of suicide and suicidal behavior were actually reduced in children who used antidepressants, despite piteous anecdotal tales in the popular press purporting that selective serotonin reuptake inhibitors (SSRIs) caused children to kill themselves. Patients in pharmaceutical trials probably do not represent typical patients in routine clinical practice. Emerging implications are that suicidal behavior-if it does occur-is most likely soon after starting antidepressant use and that prescribers must be both vigilant in educating patients and families about warning signs and available to manage worrisome behavior.

Impacting quality of life for patients with advanced cancer with a structured multidisciplinary intervention: a randomized controlled trial.

PURPOSE: The primary goal of this study was to evaluate the feasibility and effectiveness of a structured, multidisciplinary intervention targeted to maintain the overall quality of life (QOL), which is more comprehensive than psychosocial distress, of patients undergoing radiation therapy for advanced-stage cancer. PATIENTS AND METHODS: Radiation therapy patients with advanced cancer and an estimated 5-year survival rate of 0% to 50% were randomly assigned to either an eight-session structured multidisciplinary intervention arm or a standard care arm. The eight 90-minute sessions addressed the five domains of QOL including cognitive, physical, emotional, spiritual, and social functioning. The primary end point of maintaining overall QOL was assessed by a single-item linear analog scale (Linear Analog Scale of Assessment or modified Spitzer Uniscale). QOL was assessed at baseline, week 4 (end of multidisciplinary intervention), week 8, and week 27. RESULTS: Of the 103 participants, overall QOL at week 4 was maintained by the patients in the intervention (n = 49), whereas QOL at week 4 significantly decreased for patients in the control group (n = 54). This change reflected a 3-point increase from baseline in the intervention group and a 9-point decrease from baseline in the control group (P = .009). Intervention participants maintained their QOL, and controls gradually returned to baseline by the end of the 6-month follow-up period. CONCLUSION: Although intervention participants maintained and actually improved their QOL during radiation therapy, control participants experienced a significant decrease in their QOL. Thus, a structured multidisciplinary intervention can help maintain or even improve QOL in patients with advanced cancer who are undergoing cancer treatment.
