Order of onset of substance abuse and depression in a sample of depressed outpatients.
Drug abuse has been thought to cause depression, or to serve as a form of self-medication for depression. Our objective was to examine whether specific types of drug abuse preceded or followed the onset of depression. A retrospective, blinded case-controlled assessment of the drug and depressive history of depressed outpatients was conducted. Three hundred seventy-five patients with major depressive disorder were evaluated for comorbid drug dependence using the Structured Clinical Interview for DSM-III-R (SCID). They were selected from the psychiatric outpatient department of a metropolitan teaching hospital and grouped into homogeneous classes of drug dependence including alcohol, cannabis, cocaine, amphetamine, LSD, hypnosedative, opiate, and polysubstance use. We determined the percent of depressed patients with each specific type of drug abuse, their age of onset of depression and onset of specific drug abuse, and the mean number of lifetime depressive episodes for each patient. We found that alcohol dependence followed the onset of first life depression by 4.7 years (P = .02, two-tailed). Among polydrug-dependent patients, each drug abused followed the onset of depression, except for LSD, which coincided with the onset of depression. Among polydrug users, cocaine dependence occurred 6.8 years after the first major depressive episode (P = .007) and alcohol dependence 4.5 years after the onset of depression (P = .007). Opiate and sedative users had the least number of lifetime depressive episodes (3.7), and LSD and cocaine users had the greatest number (12.2). We conclude that alcohol and cocaine use in this sample of depressed outpatients conformed to a pattern of self-medication.

Somatization disorder in sphincter of Oddi dysfunction.
OBJECTIVE: Sphincter of Oddi dysfunction (SOD) is a biliary disorder with a recognized pathophysiology and demonstrated surgical treatment. We sought to examine whether women with SOD were overrepresented on measures of somatization, sexual and physical abuse, socially compliant attitudes, and familial psychiatric illness. METHOD: We matched 33 women with SOD to 33 normal controls by age, sex, and race, and, with a case-controlled cross-sectional questionnaire, compared the groups on the study variables. Statistics included a chi 2 for categorical variables, t tests for scores of somatization and attitudes of social desirability, and Pearson correlation coefficients for post hoc associations of variables. Bonferroni corrections were used with chi 2 values to reduce capitalization by chance. RESULTS: SOD patients exhibited excessive nongastroenterological somatic complaints compared with controls (p < .0001). There was a statistical increase in reports of childhood sexual, but not physical, abuse in the SOD women (p < .02) compared with controls. The severity of the abuse correlated strongly with the severity of somatic complaints. There were no differences in social desirability attitudes or family psychiatric histories of the two groups. CONCLUSIONS: We conclude that SOD is associated with a high degree of somatization in adulthood, and a mean rate more than four times that of controls in self-reports of sexual abuse in childhood. The severity of childhood sexual abuse is correlated with the severity of somatization in later life. A psychological model for this disorder is suggested by the data. Increased psychiatric attention is indicated in the treatment of women with this disorder.
Case-Control Studies↗
Bulimic vomiting alters pain tolerance and mood.
Bulimia, a disorder of episodic binging and purging, remains without a known etiology. A case report is presented of a patient who attributed bulimic episodes to efforts at inducing euphoria. Experimental pain tolerance was increased by bulimic vomiting, blocked by naloxone, but not by saline. Vomiting was also associated with falls in depression and anxiety. Plasma ACTH and cortisol, putative markers for beta-endorphin, also rose following vomiting. It is hypothesized that in some bulimics, the disorder arises by virtue of an addiction to one's own internally released endogenous opioid peptides.

Inching toward Armageddon: a psychiatric view.
The existence of thermonuclear arsenals capable of destroying much of humanity takes its origins from, and has an influence on, processes that are largely psychological. The threat to use a single nuclear bomb to resolve contemporary conflict is an anathema in part because complex nation-states did not evolve with surviving a nuclear war in mind. The atomic arms race has proceeded apace because of maladaptive psychological mechanism including denial, distortion, projection, and, most relevantly, the need to enhance bonding within groups by creating stereotypes. One consequence of the arms race is a climate of fear and hopelessness, and especially destructive effect of which is seen in children. The physician's role in the prevention of nuclear war is critical, but divided between contradictory roles. On one hand, the physician is traditionally identified as a non-political advocate of the sick; on the other, as an advocate for the public health. It is this second model that enables physicians most legitimately to work for the prevention of nuclear war and to deal with the psychiatric concomitants of a planet drifting toward disaster.
