Addiction & Substance Use

Grand mal convulsive seizures are characterized by the sudden loss of consciousness and motor inhibition, followed by tonic flexion and extension, repetitive clonic movements, and motor relaxation and lassitude. Seizures are elicited in all vertebrates that have been tested. The loss of both vigilance and the defenses of fight or flight incur life-threatening risks to the individual. In evolutionary history, we would expect this behavior to be extinguished. Its persistence prompts the query: What are the benefits of seizures?

After wading through the initial shock and horror of the murder of 32 students and faculty at Virginia Tech on April 16 by student Seung-Hui Cho, there is a natural impulse to rush to enact laws to prevent this type of tragic event from ever happening again in our schools. As professionals, as parents, as concerned members of a community, we have a felt need for an immediate response to ensure that schools are safe and secure places to learn and grow. Action is demanded. Not only must this opportunity/obligation not be squandered, but we must make sure that by our actions we do not make things worse.

Four physicians work on the same patient for days at a time, continually returning to a white board, where they list the patient's changing symptoms and their own differential diagnoses. They think inside and outside the box. As data come in from tests and as interventions succeed or fail, they remain flexible in their way of thinking. The attending physician's main lesson to his 3 fellows is to remain unencumbered by preconceived notions and to constantly revise their thinking to fit the data. Only then, he tells his trainees, is there any chance of a correct diagnosis and medical treatment.

Delirium is characterized by an altered level of consciousness, decreased attention span, acute onset, and fluctuating course. Approximately 15% of elderly patients admitted to the hospital have delirium as a presenting or associated symptom. Delirium will develop in another 15% of elderly patients during hospitalization.

In the aftermath of the tragic events at Virginia Tech, we would like to suggest some ways in which psychiatrists, psychologists, and college personnel can help identify and treat students who have severe psychiatric disorders--and perhaps prevent another mass murder.

One of the most hotly debated questions within oncology over the past decade has been whether the promotion of psychological wellness can extend survival for patients with advanced cancer. The converse--that psychiatric disorder shortens survival--seems true, with mechanisms of poor self-care and reduced adherence to anticancer treatments resultant from depressive or psychotic disorders explaining this outcome.

The 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.

The highly readable and informativesecond edition of Substance Use Disorders,by Stuart Gitlow, is a valuablehandbook for treatment providers ofall specialties.

In "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.

Medical 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.

The Science of Sleep. A quirky Indy motion picture by that title was in theaters last year. The plot concerned an odd but wildly creative and endearing fellow who ran into problems in his interpersonal relationships, in part, because he often couldn't distinguish between being awake and asleep. Wake and dream episodes mirrored each other, creating a penchant for the surreal and a personal narrative for the protagonist that wasn't quite in sync with that of the characters around him.

Personality Traits Early Clue to Distinguishing LBD From AD. Lewy body dementia (LBD) is often difficult to distinguish from Alzheimer disease (AD) but subtleties in symptoms provide clues to the differential diagnosis.

The 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.

In the first part of this column (Psychiatric Times, February 2007), I reviewed treatments whose beneficial effects are probably achieved through a discrete biological or pharmacological mechanism of action. These included dietary modifications; supplementation with specific vitamins, minerals, and amino acids; and medicinal herbs. In this part, I will review the evidence for approaches that reduce the risk of relapse, diminish craving, or mitigate withdrawal symptoms but for which there is no evidence for direct biological or pharmacological effect.

Asthma is one of the most impairing diseases of childhood, affecting more than 6% of children. Each year, it is responsible for 14 million lost school days and $3 billion in treatment costs.

Making the Connection: A Parent's Guide to Medication in AD/HD is a concise, user-friendly book intended for parents of children with attention-deficit/hyperactivity disorder (ADHD).

There were only 3 Jewish students in my high school, and I was one of them. In the small, western New York town where I grew up, most people were tolerant. But a small clique of anti-Semites made life tough for us Jewish kids. Most of the time, we just shrugged off the jokes and insults or came right back at these louts with a snappy retort. Sometimes, the bigotry grew more menacing.

A 79-year-old woman recently died in a fire at her Washington, DC, row house when "pack rat conditions" prevented firefighters from reaching her in time. A few days later, 47 firefighters from 4 cities spent 2 hours fighting a fire in a Southern California home before they were able to bring it under control. Floor-to-ceiling clutter had made it nearly impossible for them to enter the house.

"There must be some way out of here," said the joker to the thief."There's too much confusion, I can't get no relief. . . .""No reason to get excited," the thief, he kindly spoke,"There are many here among us who feel that life is but a joke.But you and I, we've been through that, and this is not our fate,So let us not talk falsely now, the hour is getting late."From "All Along the Watchtower," Bob Dylan

In The Perfect Storm, Sebastian Junger describes the desperate plight of sailors and fisherman who, in the fall of 1991, were caught out in the Atlantic Ocean as 2 powerful storms converged into 1.1 Like those mariners, emergency department (ED) clinicians find themselves at the confluence of 2 powerful trends in modern society.

The following cases highlight some of the challenges clinicians face when treating patients in whom malingerling is suspected. One key aspect of these evaluations is not overlooking signs or symptoms that point to serious illness.

aytime sleepiness is common in patients with parkinsonism but has little to do with the amount of sleep these patients get and everything to do with dopaminergic dysfunction, according to David B. Rye, MD, PhD, associate professor of neurology at Emory University in Atlanta. "The idea is that if I sleep a lot, I shouldn't be so sleepy the next day, and if I sleep little, I should be very sleepy. This is doesn't hold true for patients with Parkinson disease [PD]. The loss of dopamine disrupts that banking system, or the sleep-wake homeostat," he said during a presentation at the 9th annual meeting of the American Society for Experimental Therapeutics, which met March 8 to 10 in Washington, DC. Addressing dopa- minergic tone during sleep might help ameliorate daytime symptoms of parkinsonism in general.

Intensive therapy over short periods provides better outcomes than less intensive regimens performed over longer periods." This was the take-home message about rehabilitation for patients with aphasia from Ronald M. Lazar, PhD, professor of clinical neuropsychology in neurology and neurological surgery, and codirector of the Levine Cerebral Localization Laboratory at the Neurological Institute of New York at Columbia University College of Physicians and Surgeons.

The role of every emergency clinician is to determine whether the patient has a condition that threatens life or limb. Determining this in patients who malinger can be quite a challenge, because the malingering patient presents with false or exaggerated symptoms for secondary gain.
