Hope for Glioblastoma: Resection and New Treatments
June 1st 2007Glioblastoma multiforme (GBM) is one of the most common brain tumors and is a significant cause of morbidity and mortality.1 Primary tumors of the brain occur in about 16,000 persons and account for around 13,000 deaths annually (a mortality rate of 6 per 100,000) in the United States.
Mass Killings Are Not Incomprehensible
June 1st 2007On Monday, April 16, Seung-Hui Cho, a 22-year-old English major at Virginia Tech, shot and killed 27 students and 5 teachers before taking his own life. The reaction to this latest mass shooting included the opinion that what this young man did was beyond comprehension.
Understanding the Mind of Your Bipolar Child
May 1st 2007Childhood bipolar disorder is a devastating illness that affects emotional, social, and cognitive development. In recent years, increased attention devoted to the study of bipolar disorder in childhood has resulted in greater information regarding the cause, phenomenology, and treatment of the disorder.
The Therapeutic Potential of Neural Stem Cells
May 1st 2007The following must be one of the strangest comments I have ever heard on television. An Iraqi businessman uttered it shortly after a wave of missile strikes during the Gulf War. "The rocket flew down my street and took a left," he said in English. It had smashed into its target, a nearby building--leaving his adjacent shop completely undisturbed.
Intermittent Explosive Disorder and the Like: Overappreciated?
May 1st 2007In "Intermittent Explosive Disorder: Common but Underappreciated"(Psychiatric Times,January 2007, page 1), Arline Kaplan wrote that intermittent explosive disorder (IED) "is not just another name for bad behavior." She quoted Dr Coccaro from the University of Chicago as asserting that patients with IED who react with rage to minor irritants have been shown to have reduced down-regulation of certain cortical nuclei that should be reined in by inhibitory stimuli from the frontal cortex.
Informed Consent and Civil Commitment in Emergency Psychiatry
May 1st 2007Medical school graduation usually involves taking the Hippocratic oath, in which physicians vow not to intentionally harm their patients. Keeping patients safe is another basic principle of patient care. Physicians are charged with ensuring that their patients are in a safe environment and minimizing risks to their patients by carefully selecting treatment options.
Biopsychosocial Model: Helpful or Hindering?
May 1st 2007The points made by Dr G. Scott Waterman in his article, "Does the Biopsychosocial Model Help or Hinder Our Efforts to Understand and Teach Psychiatry?" are right on target. Unfortunately, the biopsychosocial model of psychiatry is not merely conceptual; it is woven into the delivery of care at every level. Institutions of government, insurance, and hospital and outpatient services separate "behavioral" medicine from all other medicine and further separate substance abuse disorders from those deemed "psychiatric."
How to Write a Suicide Note: Practical Tips for Documenting the Evaluation of a Suicidal Patient
May 1st 2007Proper suicide assessment is probably the most important part of a clinician's job; appropriately, heavy emphasis is placed on this in our education. Unfortunately, psychiatrists receive comparatively little practical guidance in documenting the history and physical examination (H&P) of a suicidal patient.
Physical Aggression in Dementia Patients
May 1st 2007In patients with dementia who are physically aggressive and dangerous to themselves or others, the use of intramuscular haloperidol or lorazepam may be appropriate. Because haloperidol causes less drowsiness and cognitive impairment than lorazepam, it is preferred in patients with dementia and delirium. The usual dose of haloperidol for elderly patients with dementia is 0.5 to 1 mg; this dose can be repeated every 25 to 30 minutes until the patient is no longer dangerous to self or others. If benzodiazepine or alcohol withdrawal is suspected, lorazepam is the preferred medication. Physical restraints may be appropriate until the medication takes effect.
Specificity of NMO Marker Confirmed
May 1st 2007Is neuromyelitis optica (nmo) igg autoantibody unique to NMO or is it expressed in multiple sclerosis (MS) as well? Recent studies have confirmed the autoantibody’s specificity and are shedding more light on how NMO IgG's autoantigen, the water channel aquaporin-4 (AQP4), uniquely behaves in NMO and MS.
Physicians, Proceed with Caution with Newer Aeds
May 1st 2007Patients who experience seizure 24 hours after stroke onset may be at increased risk for death, according to Angela Rackley, MD, a clinical neurophysiology fellow in epilepsy, and coresearchers at the University of Cincinnati. Rackley presented an abstract on the incidence of seizures within 24 hours after acute stroke at the annual meeting of the American Epilepsy Society in San Diego this past December. She and colleagues found a higher 30- day mortality rate among patients who had a seizure within hours of stroke compared with patients who did not experience poststroke seizure.
Partners of Combat Vets With PTSD Show Psychological Distress
May 1st 2007It is not uncommon for combat veterans to exhibit a wide range of psychological conditions, from schizophrenia to depression to posttraumatic stress disorder (PTSD), but how do these disorders affect domestic partners, who often serve as veterans' caregivers?
House and Senate Parity Bills: Differences Complicate Passage Prospects
May 1st 2007The introduction of a House mental health parity bill in March has scrambled prospects for congressional passage of a bill that President Bush could sign. The introduction of the Paul Wellstone Mental Health and Addiction Equity Act (HR 1424) by Reps Patrick J. Kennedy (D, RI) and Jim Ramstad (R, Minn) threatens to split both the mental health community and the House and Senate.
FDA Approval of Vagus Nerve Stimulation
May 1st 2007FDA Approval of Vagus Nerve Stimulation I am a triple-boarded, long-practicing psychiatrist and have used vagus nerve stimulation (VNS) in several patients so far. I have followed the controversies within the FDA and articles in the national media and was quite impressed by and appreciative of Dr Daniel J. Carlat's article on the sponsorship issues involved in FDA approval of VNS ("Conflict of Interest in Psychiatry: How Much Disclosure Is Necessary?"
Antipsychotics and Weight Gain
May 1st 2007The reason that antipsychotic medications cause weight gain is that there is increased activity of the enzyme AMP-kinase in the hypothalamus, the area of the brain that controls hunger. The increase in AMP-kinase levels occurs because antipsychotic medications interfere with the protein histamine. For some time it has been suspected that histamine plays a significant role in weight control, and these findings, from a study conducted in mice by scientists at Johns Hopkins University, confirm this. The researchers hope that these findings will contribute to the development of a new class of effective antipsychotics that do not cause weight gain.
