FDA Tries to Bridge Data Divide With New Antidepressant Warnings
March 3rd 2007The FDA finds itself straddling a data divide as it decides how to rewrite the black box warnings on the labels of SSRI antidepressants. The agency will almost certainly mandate that the existing black box warning, which addresses suicidality in children and adolescents, be expanded to include young adults up to age 25 or 30. But in what might be a pioneering move for the FDA, the agency will probably also include new verbiage in the warning related to the benefits of antidepressants to people over the age of 30 years.
Drug Effects: Do Test Results Correlate With Clinical Gains?
March 3rd 2007There are any number of ways to measure the effects of psychoactive medications, ranging from objective assessments of behavioral change to neuropsychological testing to subjective global ratings by physicians or patients. Several recent studies have examined the question of whether medication-induced improvements in neuropsychological test performance correlated with gains in healthful functioning.
New Data on Violent Deaths Available
March 1st 2007According to the Centers for Disease Control and Prevention (CDC), there are approximately 50,000 violent deaths each year in the United States. Until recently, there were no comprehensive data available to the public regarding these deaths. It was with this in mind that the National Violent Death Reporting System (NVDRS) was created, not only to provide statistics of reported violent deaths, but also to educate and possibly prevent more violent deaths from occurring.
Panic Disorder: Telemedicine Gives Encouraging Results
March 1st 2007Treatment interventions via telephone, Internet, and through other telemedical services are gaining popularity, especially in rural areas where licensed clinicians might not be available. Dr Per Carlbring and colleagues recently evaluated a 10-week, Internet-based, self-help program with weekly telephone calls for patients who had panic disorder with or without agoraphobia. The results were published in the December 2006 issue of the American Journal of Psychiatry.
Increased Plasma Cortisol Levels Associated With Alzheimer Progression
March 1st 2007Increased plasma cortisol levels (correlated with increased hypothalamic-pituitary-adrenal axis activity) may be associated with more rapid disease progression in Alzheimer-type dementia (AD). In a study conducted at the Washington University School of Medicine in St Louis, Dr John Csernansky and colleagues assessed 33 patients with very mild or mild AD and 21 persons without AD annually for up to 4 years, using the Clinical Dementia Rating Scale and various neuropsychological tests. Plasma was obtained from each patient and assessed for cortisol level.
A New and Better Search Engine for Psychiatrists
March 1st 2007In 2006, Psychiatric Times upgradedits Web site (www.PsychiatricTimes.com) to make it more user-friendlyand to provide more features of interestto our readers. As another step to enhancethe value of the Web site, PsychiatricTimes recently introduced a newsearch engine SearchMedica/Psychiatry.
Major Depression on the Rise in the United States
March 1st 2007Treatment interventions via telephone, Internet, and through other telemedical services are gaining popularity, especially in rural areas where licensed clinicians might not be available. Dr Per Carlbring and colleagues recently evaluated a 10-week, Internet-based, self-help program with weekly telephone calls for patients who had panic disorder with or without agoraphobia. The results were published in the December 2006 issue of the American Journal of Psychiatry.
Mental Health Drugs at Issue in Part D Debate
March 1st 2007The price and availability of psychiatric drugs is expected to be one of the major issues as Congress decides whether to try to find a way to force pharmaceutical manufacturers to lower the prices they charge Medicare Part D drug plans. Antidepressants, antipsychotics, and anticonvulsants are among the 6 categories for which Part D formularies must make available "all or substantially all" medications. As a result, the formularies are unable to bring to bear the drug price reduction strategies they use in other categories.
Damage to Part of the Brain May Aid Smoking Cessation
March 1st 2007Damage to part of the brain may cause persons addicted to nicotine to "forget" to smoke, a recent press release from the National Institute on Drug Abuse (NIDA) claims. Preliminary research showed that smokers may find it easier to quit after suffering damage to the insula.
Treatment-Resistant Depression: Figure Clarification
March 1st 2007I was disappointed to see the Figure titled Olanzapine and fluoxetine in the treatment of TRD in the article Treatment-Resistant Depression: Strategies for Management" ( Psychiatric Times, page 34) in the October 2006 special bonus edition.
Pediatric Cancer Survivors at Risk for Stroke
March 1st 2007Childhood survivors of brain tumors and leukemia are at particular risk for stroke later in life, according to research conducted through the University of Texas (UT) Southwestern Medical Center at Dallas.1 The medical center is one of 26 facilities involved in the Childhood Cancer Survivor Study (CCSS), a large, ongoing research investigation on the long-term effects of cancer and its treatment in the pediatric population.
Looming Technological Imperatives and the Physician-Patient Relationship
March 1st 2007The past decade has seen an explosion of new drugs, procedures, and technology. This upward trajectory of health care breakthroughs shows no sign of slowing; such innovations as molecular imaging and pharmacogenetics are within years of going prime time.
News From The International Stroke Conference 2007, San Francisco, February 7-9, 2007
March 1st 2007Although current guidelines require physicians to confirm whether a patient’s platelet count is 100,000/µL or higher before administering tissue plasminogen activator (tPA), researchers concluded that this testing might be a poor use of precious time. Bryon P. Jackson, MD, an intern, and colleagues at the University of Pennsylvania Medical Center, Philadephia, conducted a retrospective record review of patients with ischemic stroke. He and coresearchers determined which patients had a platelet count lower than 100,000/µL and whether these patients had a known history of thrombocytopenia or conditions associated with this disorder, such as metastatic cancer, hematologic malignancy, or recent bleeding, or presentation with sepsis or shock.
Raising the Bar on ALS Care: It's Possible and Appreciated
March 1st 2007Presenting a diagnosis of amyotrophic lateral sclerosis (ALS) is one of the most difficult tasks that a neurologist may have to undertake. Despite the tragic quality of the news, experts in ALS care are exhorting fellow neurologists not to give up on patients in whom ALS is diagnosed.
The Clinical Management of Amyotrophic Lateral Sclerosis
March 1st 2007Amyotrophic lateral sclerosis (ALS) is a progressive, debilitating, fatal disease that involves degeneration of upper and lower motor neurons. Patients often initially present with limb or bulbar weakness, atrophy, and spasticity, followed by progressive loss of ambulation and, ultimately, respiratory failure, which is the most common cause of death.
Parent Project Muscular Dystrophy: Advocacy and Support
March 1st 2007The diagnosis of Duchenne muscular dystrophy (DMD) is devastating for patients and their families. There is no standardized treatment and no cure, and boys with this disorder typically die by age 25 years because of respiratory failure or failure of the heart muscle. Until 13 years ago, parents of boys with DMD had nowhere to turn for support and no concerted efforts in clinical research were being made. This changed in 1994 with the founding of Parent Project Muscular Dystrophy (PPMD), a grassroots organization started by parents with the goal of creating awareness of DMD and generating interest and funding for research.
Stroke Complications: Hiding in Plain Sight?
March 1st 2007Despite the enormous progress made in stroke diagnosis and treatment in recent years, patients continue to experience stroke-related deficits that clinicians-even those working on stroke rehabilitation units-do not always recognize or record. In a recent study of 53 patients who underwent screening tests within 10 days of admission to a stroke unit, every impaired patient had at least 1 undocumented cognitive or sensory deficit. The authors suggested that without formal testing with standardized assessments, much stroke-related impairment goes unrecognized and perhaps untreated.
Nondrug Treatments for Neuropsychiatric Symptoms in Dementia
March 1st 2007Given the lack of a good evidence base for pharmacological treatment of neuropsychiatric symptoms of dementia, are there any effective treatments for such problems as agitation, aggression, delusions, hallucinations, repetitive vocalizations, and wandering? A recent review suggests that nondrug interventions that address behavioral issues and unmet needs may be helpful, as may caregiving interventions and the use of bright light therapy.
Recognition of Amygdala Abnormalities in ASDs Spurs Rehabilitative Modalities
March 1st 2007Recent imaging studies have shown that patients with autism spectrum disorders (ASDs) who were presented with images of human faces had lower responses in amygdala activity than controls. These studies strengthen the connection between the amygdala and the abnormal social-emotional behavior seen in patients with ASDs, said Chris Ashwin, PhD, senior research associate at the Autism Research Centre in the Department of Psychiatry at the University of Cambridge, UK.
Comorbidity of Bipolar and Panic Disorders and Its Consequences
March 1st 2007Panic disorder occurs in about 1 in 5 individuals who have bipolar disorder. Anxiety amplifies the distress caused by depression and mania, but pharmacological approaches are tricky and under-studied. Frequent comorbidity and evidence of a possible genetic relationship of bipolar and panic disorders are suggestive of a causal relationship between the 2. Thus, it may be fruitful to look more closely at evidence for common biological abnormalities in both disorders to find a pathophysiological mechanism that links mania, depression, and panic attacks. Mood episodes and panic attacks can both be modeled as the result of deficits in amygdala-mediated emotional conditioning. From this model, some insight may be gained for potentially helpful treatment strategies for the 2 disorders when they occur together.
Broken Sleep May Be Natural Sleep
March 1st 2007Once again your patient, an accountant and tax specialist, is complaining about his sleep. More nights than not he awakens at about 2 am. An hour goes by, sometimes 2, before he returns to sleep. You've prescribed 4 different hypnotics. Each gave the same unsatisfactory result. For 2 weeks, your patient got the 8 hours of uninterrupted sleep he-and you-seek, but then the old pattern returned. Following your instructions, he avoids caffeine, doesn't exercise after 6 pm, and confines his activities in bed to sleep, but to no avail. You refer him to a sleep laboratory, and the results there are entirely consistent with what he's been telling you. In the sleep lab he falls asleep at 11 pm, awakens at 2:30 am, returns to sleep at 4 am, and awakens for good at 7:30 am. He does not have sleep apnea, restless legs syndrome, or depression.
STAR*D Starts to Resemble Practice
March 1st 2007When clinical practice appears to diverge from evidence-based medicine, is the clinician departing from science, or are the data not applying to practice? The challenge of developing clinical research data to inform treatment strategies for the inconstant course of psychiatric illness was recently considered by Susan Murphy, PhD, of the University of Michigan's Institute for Social Research, with colleagues from the MCATS (Methodology for Constructing Adaptive Treatment Strategies) network, and John Rush, MD, of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) investigators group.
