In this overview of pica, we review its causes and prevalence. In addition, we discuss some of the associated complications as well as current treatment strategies.

Although several antimanic agents are available to treat individuals with bipolar disorder (BD), many patients have a less than satisfactory response or experience adverse effects.1 With the exception of lithium, all of the current antimanic agents are either anticonvulsant or antipsychotic drugs. It is remarkable that no drug has been developed specifically for BD, especially because this illness was conceptualized more than a century ago.

This article discusses the role of µ-opioid receptors (MORs) in antidepressant treatment and major depressive disorder (MDD). Specifically, it focuses on how the endogenous opioid system affects response to pharmaceuticals.

Since the discovery of dopamine as a neurotransmitter in the late 1950s, schizophrenia has been associated with changes in the dopaminergic system. However, the dopamine hypothesis of schizophrenia cannot explain all the symptoms associated with this disorder. Therefore, research has also focused on the role of other neurotransmitter systems, including glutamate, g-aminobutyric acid, serotonin, and acetylcholine (ACh) in schizophrenia.

The vesicular monoamine transporter (VMAT) is a membrane-embedded protein that transports monoamine neurotransmitter molecules into intraneuronal storage vesicles to allow subsequent release into the synapse.1,2 By accumulating both newly synthesized neurotransmitter molecules and freshly returned neurotransmitter molecules from the synapse, VMAT function plays a critical role in the signaling process between monoamine neurons. The VMAT exists in 2 distinct forms: VMAT1 and VMAT2.3

Everyone would probably agree that the practice of clinical psychiatry has changed profoundly over the second half of the past century. One of the most remarkable changes has been the rapid development and expansion of clinical psychopharmacology, which has become, like it or not, a dominant part of the clinical practice of most psychiatrists. Available treatments for mental disorders changed and our armamentarium broadened. We have numerous medications for psychiatric disorders. We even use medications for disorders traditionally considered only amenable to and suitable for psychotherapy.

The modern era of psychopharmacology is only 60 years old, having begun with the discovery of the psychotherapeutic benefits of reserpine, lithium, monoamine oxidase inhibitors, and chlorpromazine in the late 1940s and early 1950s, which was followed a few years later by the synthesis and testing of the tricyclic antidepressants and benzodiazepines.

If you had asked me a year ago if I could have faced what I am about to describe and come out on the other side I would have said "Hell, no!" It has been a year of pain and struggle, and although certain parts cannot be changed, I still think that if things had been handled a little differently I might not have gone through some of what I did. Here is my story.

"I've lost my interest in sex." As psychiatrists, we hear this concern (if we ask) from women in a variety of situations: those who are depressed, postpartum, menopausal, traumatized, and those who have been treated with psychotropic medications. Thankfully, we have many interventions, both behavioral and pharmacological, to use in addressing sexual issues.

The expression "quality of life" is an intuitively familiar and popular concept, and it epitomizes the public's hopes and expectations. In clinical settings, it demands the inclusion of patients' feelings, attitudes, and opinions in medical decision making.

Vietnamese Amerasians and the former political prisoners of South Vietnam are living legacies of the Vietnam War. Now that many live in the United States, it is important for psychiatrists to have an understanding of their life experiences and be able to recognize psychiatric disorders that are common among them.

The ocurrence and severity of anxiety disorders have been correlated with fluctuations in female sex steroid levels in both epidemiological and experimental studies.1-5 Female reproductive hormones play a role not only in the development and course of anxiety disorders but also in treatment response.

Suicide is a devastating, tragically frequent outcome for persons with varying psychiatric conditions, including schizophrenia. An estimated 5% to 10% of persons with schizophrenia commit suicide and 20% to 50% attempt suicide during their lifetime.1,2 Patients with schizophrenia have more than an 8-fold increased risk of completing suicide (based on the standardized mortality ratio) than the general population.3

The cultural and demographic profile of the United States is undergoing a rapid transformation. In many areas of the country, there is no longer an ethnic majority but a multiplicity of racial and cultural groups.

A variety of conditions may account for the sleep difficulties experienced by many older adults, including specific sleep disorders, circadian rhythm disturbances, and medical and psychiatric comorbidities.

The 1994 death of Nicole Brown Simpson and the subsequent highly publicized murder trial of her ex-husband, O.J. Simpson, brought increasing national attention to the problems of domestic violence and intimate partner murder. In 2000, there were 1247 female victims of intimate partner murder in the United States.1 Fully one third of female murder victims were killed by an intimate partner.1 On the positive side, rates of female victimization by intimate partner violence and murder appear to have decreased in the recent past.

"Jack" has been in our emergency department at least 100 times in the 4 years I have worked at the Veterans Affairs Hospital. I first encountered him in the medical ICU, where he was hospitalized multiple times with chest pain and ECG changes after cocaine binges.

An international team of experts recently proposed expanding the diagnostic criteria for several subtypes of bipolar disorder, adding a pediatric bipolar disorder category and eliminating the schizoaffective disorder category.

Medical journals have a unique image in the US health care system. Because most of them adhere to a strict system of critical peer review, they are often seen as unimpeachable sources of accurate information about the safety and efficacy of new medications.

Recently, a number of studies have examined the characteristics of early-onset schizophrenia spectrum disorders and medication treatment for youths with schizophrenia.

Why is it that experiencing a new love relationship or coping with a severe crisis has such different outcomes for different persons?

Over the past 2 years, I have struggled with my dual role as a resident and a mother. My husband and I moved to the United States in 2002 with high hopes and expectations.

The Supreme Court's 2006 decision in Clark v Arizona1 was one of the most unexpected defeats the American Psychiatric Association (APA) has had since it began regularly submitting amicus briefs to the Court 35 years ago.

Nearly one sixth of the world's population has experienced mass violence, be it abducted Ugandan children who are forced to commit atrocities against their families and serve as child soldiers or Iraqi civilians who daily live with bomb blasts, killings, and sectarian violence.

Evidence-based medicine (EBM) is rapidly becoming the norm. It is taught in medical schools and is encouraged by both government agencies and insurance plan providers. Yet, there is little proof that this model can be adapted to fit psychiatry.

In the second century ad, a brilliant physician had a powerful idea: 4 humours, in varied combinations, produced all illness. From that date until the late 19th century, Galen's theory ruled medicine. Its corollary was that the treatment of disease involved getting the humours back in order; releasing them through bloodletting was the most common procedure and was often augmented with other means of freeing bodily fluids (eg, purgatives and laxatives).

In 2006, substance dependence or abuse was diagnosed in about 22.6 million persons in the United States.1 Addiction-related morbidity and mortality pose a major burden to society, costing our economy more than $500 billion annually: about $181 billion for illicit drugs,2 $168 billion for tobacco,3 and $185 billion for alcohol.4

In my work in sexual boundary violations, now spanning almost 25 years, there are 2 things that have not changed. One is the prevalence or the frequency of at least one type of sexual boundary transgression.

Psychiatrists more than any other medical specialists would benefit from regular doses of poetry, art, and fiction.

In the historical context of American psychiatry, the concept of boundaries is a relatively recent development.1 Freud reportedly analyzed some patients while walking along the river Danube, gave patients gifts, and was known to share a meal with a patient.
