Is Psychiatry Dishonest?

1305_SBR_BOOKOFWOE_ILLO

Illustration by Lisa Hanawalt

When I think of psychiatry, my first thoughts are unkind. I think of mildly sad people on antidepressants. I think of upper-middle-class parents putting their kids on Ritalin as soon as they flunk math, or misremember the lyrics to Dave Matthews songs. Pills seem so overabundant in our country that it?s possible to forget there are Americans who really and desperately need a pharmacological fix for an illness of the mind.

Early in The Book of Woe: The DSM and the Unmaking of Psychiatry, Gary Greenberg describes one such American, a patient who locks himself in a hotel room and gibbers into the phone that his family has sucked out his bones. People like this look to psychiatry for salvation, and so, Greenberg argues, we must save the profession from overreach and corruption. These twin problems have become so dire in the last few years that even pillars of the psychiatric establishment have started to howl in protest. The Book of Woe is the behind-the-scenes story of the new, fifth edition of the American Psychiatric Association?s bible, the DSM-5, and it?s entertaining in some of the same ways that Moby-Dick is entertaining. The psychiatrists Greenberg interviews are willful, sharp-tongued men?they are mostly men?stuck on the same rickety ship, trying to chart a common course, and bound for disaster.

Greenberg quotes Melville, declaring that too many psychiatrists ?cherish expectations with regard to some mode of infallibly discovering the heart of man.? (Melville was referring to ?earnest psychologists,? but that?s because psychiatry didn?t yet exist as a profession.) He wants them to stop acting like they know the truth about their patients? minds. The repository of their contested knowledge is the DSM, which stands for Diagnostic and Statistical Manual of Mental Disorders, a wildly profitable taxonomy of illnesses that costs $189 and projects an air of medical authority by defining disorders with lists of criteria. The problem with these disorders, Greenberg argues, is that they treat the mind like the body. Trying to make their profession look like any other branch of medicine, psychiatrists treat undefinable mental states like ?anxiety? as if they were scarlet fever.

For example, as of June 2011, the first three criteria for Generalized Anxiety Disorder (GAD) in a draft of the DSM-5 were:

A. Excessive anxiety and worry (apprehensive expectation) about two (or more) domains of activities or events (e.g., family, health, finances, and school/work difficulties).

B. The excessive anxiety and worry occurs on more days than not, for 3 months or more.

C. The anxiety and worry are associated with one or more of the following symptoms:

1. restlessness or feeling keyed up or on edge

With scarlet fever, you can trace the symptoms to the presence of strepococcus bacteria in the body. With GAD, you must hope that you and your patient are properly measuring unquantifiables like ?excessive,? ?restlessness,? and ?keyed up.? Greenberg is a psychotherapist?as well as a widely published journalist and author?and he believes psychiatrists must make clear to patients that such disorders are not diseases but ?provisional categories.? This, he predicts, will mean ?fewer patients, more modest claims about what [psychiatry] treats, less clout with insurers, and reduced authority to turn our troubles into medical problems simply by adding the word disorder to their description.?

He sees this humbling of the discipline as the path to an ?honest psychiatry.? A nimble rhetorician, Greenberg implies that in its current state psychiatry is like the titular swindler of Melville?s The Confidence-Man, from which that ?heart of man? quotation is drawn. Psychiatrists, he says, must learn restraint. They must say ?I don?t know? more often. Because, from some angles, the profession looks like a confidence game. If it?s a scientific study of the mind, rather than simply a mirror of our cultural values, why was homosexuality listed as a disorder in the DSM until 1973? Go back even further in the annals of mental illness, and you find drapetomania, proposed by the New Orleans physician Samuel Cartwright in 1850: ?the disease causing negros to run away.?

Lest you believe we are in an era free from politically fraught mental disease, Greenberg notes that the DSM-5 looks set to apply Hoarding Disorder to people who collect piles of old newspapers, but not to people who collect astounding compensation packages while laying off employees. And lest you deem these concerns academic, Greenberg points out that psychiatrists hungry for grants from Big Pharma can, for instance, revise the boundaries of bipolar disorder so that disobedient toddlers are prescribed antipsychotics. Harvard psychiatrist Joseph Biederman advanced the notion of childhood bipolar disorder while accepting research funds from Johnson & Johnson, manufacturer of one of the antispsychotics often prescribed to the allegedly bipolar children. Eventually Sen. Chuck Grassley of Iowa ordered an investigation of Biederman?s activities and Harvard determined that Biederman violated its policies.?

Greenberg?s case is compelling. But he smartly devotes equal time to an alternative rescue plan advocated by Allen Frances, chief architect of the DSM?s previous edition, the DSM-IV. (The APA has switched from Roman to Arabic numerals.) Much of the drama in The Book of Woe flows from the tortured intellectual bromance of Greenberg and Frances, who are a bit like Ishmael and Ahab. Frances has a white whale he wants to slay, the DSM-5, which he considers rife with imprecision. He has launched a ferocious publicity campaign against it, arguing that its methodology must be overhauled if psychiatrists are to retain their credibility. Greenberg, like Ishmael, plays the bemused outsider. He?s not sure there should be a DSM at all. His role is mostly to stand by and watch the bloody spectacle.

As presented by Greenberg, Frances? view is that psychiatry can maintain the public trust and protect patients by being both more stringent and more open about the way mental disorders are defined. The DSM needs better field trials, clearer boundaries for many mental illnesses, and less deference to well-placed experts who want to get their off-the-cuff diagnoses in the book. He believes the manual-in-progress is full of the mischief he regrets allowing in DSM-IV: sloppy, poorly tested diagnostic categories and pet disorders promoted by insiders. Frances wants a ?black-box warning about the dangers of overdiagnosis.?

But?and this is where it gets really interesting?Greenberg depicts Frances as having much the same doubts about psychiatry?s fundamental scientific validity as Greenberg himself. He suspects that Frances, despite having supervised the writing of the DSM-IV, knows just as well as he does that psychiatry is ?built on air.?

But Frances says that if patients come to understand the limitations of psychiatry, they might fail ?to do the calculation.? They might fail to conclude, ?Well, maybe this isn?t perfect, but it?s still the best way available, and we shouldn?t just throw it out.? They might ?get disillusioned and stop taking their medicine.? Frances wants to maintain the prestige of the profession until neuroscience improves, and ?the complexity begins to clarify out of the mist.?? Until then, ?the full truth is usually best, but sometimes we may need a noble lie.? Frances, whom the New York Times once called ?perhaps the most powerful psychiatrist in America,? understands, according to Greenberg, that because we cannot yet create ?a taxonomy of disorders validated by biochemical findings,? psychiatry as we know it is a collection of fictions.

Penguins set tone with 5-0 romp over Islanders

PITTSBURGH (AP) ? The rookie scored. So did the enforcer. The Norris Trophy-candidate defenseman too. And the underrated forward in the midst of a career season did it twice.

Not bad for a team missing arguably the best player on the planet.

The Pittsburgh Penguins crushed the New York Islanders 5-0 in their playoff opener on Wednesday night, looking very much like a Stanley Cup contender even with captain Sidney Crosby relegated to well-dressed cheerleader due to a broken jaw that isn't quite healed.

And maybe that ? and not the way the Penguins toyed with an eighth-seed making its first playoff appearance in six years ? is the scary part.

"He's Sid so it will be amazing when we do get him back," forward Jarome Iginla said. "It speaks for itself. He controls games with his speed and everything he does; it will be great when we do get him back. Hopefully, it's the next game. I know he's close. The focus is just to keep trying to play well as a group."

So far, so very good.

Pascal Dupuis scored twice, Marc-Andre Fleury tied a franchise record with his sixth career shutout and the Penguins showed few weaknesses in their quest to bookend the Stanley Cup they won in 2009.

Not that Pittsburgh is getting ahead of itself after three straight early exits from the postseason.

"It's one win," Dupuis said. "We definitely feel good about it but we've just got to put this one behind us and get ready to work for the next one. They'll definitely look at tape and come out harder, that's for sure."

The Islanders will have to have any hope of making the series competitive. Looking to win a playoff series for the first time in 20 years, New York fell behind less than 5 minutes in and never recovered.

"I thought some guys worked hard and played a good game," Islanders coach Jack Capuano said. "Again, with our club we need all 20 guys going, and we didn't have all 20."

That isn't an issue for the staggeringly deep Penguins.

Rookie Beau Bennett, grinder Tanner Glass and defenseman Kris Letang also scored for Pittsburgh.

The Penguins wasted no time in pouncing on the Islanders, beating Evgeni Nabokov four times in the game's first 22 minutes, including goals by Letang and Dupuis 32 seconds apart early in the second period. That sent Nabokov to the bench after he stopped just 11 shots.

Kevin Poulin came on in relief and surrendered a soft goal to Glass. Capuano said it is too early to decide who will start in goal for Game 2 on Friday night.

Whoever it is will need help from the guys in front of him. The Islanders' playoff drought soon will be at 21 years if they can't keep Pittsburgh's skaters in check.

"When you make it easy on them, they're going to light you up," New York forward Matt Martin said. "For most of the game we made it pretty easy on them, and if you do that they're just going to run up the score on you."

Pittsburgh rolled to the top of the East even though Crosby missed the final quarter of the season. The Penguins have been bolstered by the arrival of trade deadline acquisitions Iginla, Brenden Morrow, Jussi Jokinen and Doug Murray.

All four players are searching for their first Cup championship, and all four made an immediate impact in the series opener. Iginla and Jokinen both had two assists, and Morrow and Murray helped bottle up New York captain John Tavaraes.

The Islanders star failed to find much room to maneuver and didn't muster a shot on goal all night.

"We're going to need to (forget it quickly)," Tavares said. "These series are long, but they can be real quick, too."

Those who did get pucks in on Fleury didn't fare any better. He turned aside all 26 shots he faced, receiving a boost from a group that blocked 17 shots before they even got to the net.

Capuano insisted his team ? which had 16 players making their postseason debuts ? wouldn't be overcome by the moment. Still, the Islanders looked jittery.

The Penguins, not so much even with the lines seemingly in a constant state of flux.

"We play one way," Dupuis said. "It doesn't matter who you play with. Anybody you play with, you play with great players."

NOTES: Pittsburgh F James Neal left in the second period with an undisclosed injury and didn't return. ... Jokinen left with 2:20 to play after taking a hit to the knee from New York's Marty Reasoner. ... The Islanders went 0 for 4 on the power play. ... Pittsburgh D Brooks Orpik was scratched due to a lower body injury. ... New York's loss was its second in regulation since March 30.

Paramilitary soap opera stirs dispute in Colombia

BOGOTA, Colombia (AP) ? Cutting through the shadows of moonlight, three brothers climb out of a truck and trudge slowly, silently toward a dark hill. There, wrapped in a blanket, they find the body of their father.

At the burial shortly afterward, amid tears and embraces, the brothers vow vengeance against the leftist rebels who kidnapped and killed him.

It's a crucial moment in a Colombian paramilitary soap opera that has stirred unprecedented controversy by dramatizing ? and some say romanticizing ? the career of the Castano brothers, central figures in the creation of the country's murderous far-right militias.

While founded to fight leftist guerrillas, the United Self-Defense Forces of Colombia evolved into criminal gangs, enriched by drug trafficking, that killed thousands and stole land from tens of thousands more, colluding with scores of prominent politicians.

The soap opera is called "Three Cains," an allusion to the Biblical story of Cain slaying his brother Abel, in part because Vicente Castano had his brother Carlos murdered in 2004.

A grassroots campaign against the show, which runs on the Mundo Fox cable channel in the United States and RCN in Colombia, also has raised questions about a whole genre of Colombian TV series that focuses on the country's top drug traffickers. Some say such shows glorify killers while minimizing victims.

"It's clear that those topics have to be dealt with. The question is, why treat them from the point of view of Cain and not Abel?" said Daniel Naranjo, who with three friends launched a Facebook campaign promoting an advertising boycott against the series that has gained thousands of supporters.

Instead of focusing on the Castano brothers, or the late drug kingpin Pablo Escobar, he asked, why not instead focus on their victims?

"Three Cains" portrays the brothers in their loves as well as their conflicts ? aspects of their lives that were sometimes entangled, at least on the screen, as they sent killers after romantic rivals or those who betrayed them. The first few weeks also have traced the Castanos' secret alliance with police and soldiers to attack Escobar and his allies.

Less detail so far has been given to incidents such as the January 1990 Pueblo Bello massacre, in which the brothers' gang kidnapped 43 peasants, loaded them into trucks, hauled them away to a family ranch and killed them, according to the Inter-American Human Rights Court. The Castanos allegedly believed at least some of the villagers had aided rebels who had stolen cattle from them.

Among the dead was Wilson Fuentes, a 45-year-old banana farmer and rancher. For his daughter Katy, who was 14 when her father was seized, the series is an affront.

"It makes me re-live that moment," she said. "What it does is re-victimize us ... It's a lack of respect for the victims."

Her father's body, like most of those slain, was never found, and the possible explanations say much about the Castanos' reputation. "There are many versions," Fuentes said. "Supposedly they had an oven; they tossed them in the oven and they were incinerated. Other versions say they had some lions and they gave them to the lions to eat. Others say they threw them into the Sinu River."

"The truth, nobody knows," said Fuentes. "Or if they know, they do not want to say."

The fate of two of the Castanos themselves is a mystery as well. While Carlos was killed in 2004, just as the paramilitaries were disbanding as part of a peace deal with the government, Fidel and Vicente both disappeared under murky circumstances. Carlos had long maintained that Fidel died in combat in the 1990s but no corpse was ever recovered. Vicente's fate is unknown.

While some earlier TV series generated protests, the campaign against "Three Cains" is the first to prompt sponsors such as the Falabella chain of stores and Nivea cosmetics to pull backing from a show, local media analysts say.

Even so, the show is winning viewers. It has been among the top five most-viewed programs on Colombian television during its run.

RCN Television, which produced the show and is the target of the protests, refused to comment on the complaints when contacted by The Associated Press. A screenwriter for the series, Gustavo Bolivar, rejected the campaign against it as "bordering on censorship" and denied glorifying the criminals.

"We are showing how these drug traffickers became paramilitaries and these paramilitaries attacked the civilian population," he said.

A chapter of Colombia's history "is being told, for good or ill," Bolivar said. "Those who want, watch it. Those who don't have the remote control in their hands and can watch another program."

Still, the societal trauma from Colombia's seemingly interminable conflict ? the paramilitary phenomenon is just one offshoot of a nearly half-century-old guerrilla conflict ? is so deep that many are offended by an attempt to earn television ratings by dramatizing it.

"The issue is that paramilitarism is still a relatively recent topic, so sectors of the population still have an open wound," said Jeronimo Rivera, head of the audiovisual department at the University of La Sabana in Bogota.

For sociologist Miguel Angel Hernandez of the University of the Atlantic, the show's depiction of huge houses, luxurious cars and numerous bodyguards leaves the message "that evil pays."

"Evil pays for 95 percent of the series and in the 5 percent at the end it says that evil does not pay. Why"? So it can be, let's say, presentable before public opinion."

Researchers look to mathematics, nature, to understand the immune system and its role in cancer

May 1, 2013 ? Can the patterns in tree branches or the meandering bends in a river provide clues that could lead to better cancer therapies? According to a new study from Virginia Commonwealth University Massey Cancer Center, these self-similar, repeating patterns in nature known as fractals help scientists better understand how the immune system is organized and may one day be used to help improve stem cell transplant outcomes in leukemia patients by predicting the probability of transplant complications.

Recently published in the journal Biology of Blood and Marrow Transplantation, the study led by Amir Toor, M.D., found a fractal pattern in the T cell repertoire of 10 unrelated stem cell transplant donors and recipients. T cells are a family of immune system cells that keep the body healthy by identifying and launching attacks against pathogens such as bacteria, viruses or cancer. T cells have small receptors that recognize antigens, which are proteins on the surface of foreign cells. Once T cells encounter a foreign cell, the antigen fits into the T cell's receptor like a key in a lock and the T cell's deadly arsenal is unleashed on the threat. Once activated, T cells divide into many clones with receptors designed to recognize and guard against that specific pathogen. Over the course of a person's life, he will develop millions of these clonal families, which make up his T cell repertoire and protect him against the many threats that exist in his unique environment.

"The technological advancements of high throughput sequencing have only recently allowed scientists to sequence the genetic material responsible for T cell repertoire. At first glance, the data looks like a chaotic jumble of information," says Toor, a hematologist in the Bone Marrow Transplant Program and researcher in the Developmental Therapeutics program at VCU Massey Cancer Center. "However, if you study a person's T cell repertoire by analyzing the DNA segments responsible for the various types of T cell receptors, you begin to notice a fractal pattern based on segment usage." Toor and his team are hopeful that this information will give them clues that will help them better understand the recovery of immune function following stem cell transplantation and possibly predict complications such as graft-versus-host disease in transplant recipients.

Much like a child can assemble Lego blocks to create a range of different models, humans have evolved a highly efficient process by which a short span of the genome called the T cell receptor locus rearranges gene fragments to create a multitude of different T cell receptor families. In this process, DNA segments known as variable (V), diversity (D) and joining (J) segments are rearranged to create the millions of T cell receptor families, or clones, that the body uses to combat disease. Similar to how the branching pattern of a tree is faithfully replicated from the trunk all the way to its farthest branches, T cells have families that are created from DNA segments branching out from one another to form a shield that provides protection from diseases.

Toor's team looked at the frequency of T cell clones bearing different V, D and J segments in stem cell transplant donors and recipients following stem cell transplantation. Using a circular diagram designed by researcher Jeremy Meier, B.S., to better visualize the arrangement of the different DNA segments, the team observed a similar fractal order in the T cell receptor families of the donors. This order was even apparent in donors of different ethnicities living on different continents. In patients who had received a stem cell transplant, Toor found that this pattern was disrupted and the patients displayed a lower level of complexity in their T cell receptor repertoire at three months after transplant, followed by a modest improvement when a full year had elapsed after transplantation.

"Attempting to restore the fractal order of a patient's T cell receptor repertoire by optimizing the stem cell transplant process could serve as a valuable therapeutic target," says Toor. "Additionally, our findings lend an insight into nature, such that even in complex biological systems bereft of physical form, mathematically determined organization is observed."

Toor and his colleagues plan to continue using high throughput sequencing of patients' T cell receptors to learn more about how the immune system recovers following stem cell transplantation. The team hopes this will give them valuable information about the effectiveness of future stem cell transplant and immunotherapy clinical trials developed in their clinic.
