Post-traumatic stress symptoms and distress following acute burn injury.

The occurrence and predictors of acute post-traumatic stress symptoms were assessed in a large, prospective sample of persons with new burn injuries (N = 172). Participants completed a self-report post-traumatic stress symptom checklist, pain ratings, and a premorbid mental health inventory within 24 h of admission to a burn center (Day 1). Over half of the sample reported sleep disturbance and recurrent, intrusive recollections of the burn injury on Day 1. Other commonly endorsed symptoms were difficulties concentrating, avoidance of thoughts/feelings associated with the burn, flashbacks, and exaggerated startle response. Persons with less favorable premorbid mental health and larger burns reported a greater number of stress symptoms on Day 1. These results suggest that experiencing some post-traumatic stress symptoms immediately following a burn trauma is normal. It is recommended that burn care professionals identify and intervene with patients who are suffering clinically significant distress early in the hospitalization.

Human rights of psychiatrically disturbed persons in the tropical Pacific.

The management of acutely disturbed patients in smaller Pacific island communities presents many clinical challenges as well as ethical and human rights questions. The aggressive, excited, sexually inappropriate, and possibly violent disturbed person frequently will need physical restraint and possible seclusion in a secure environment. In practical terms, on many Pacific islands the only physically secure room is a jail cell. This environment will protect others and possibly protect the out-of-control person from themselves. After protection, the next requirements are adequate information about the person and clinically informed individuals who can make a diagnosis and commence treatment in the jail environment. Adequately trained people who can diagnose and suggest initial treatment are few and widely dispersed in Pacific island communities. Two representative case vignettes from the author's experience as a World Health Organization short-term consultant in Tonga and the Commonwealth of the Northern Mariana islands illustrate the tension between a disturbed person's right to adequate treatment and the right of a citizen/patient to be free of coercion.

A profile of medically serious suicide attempts.

BACKGROUND: This study identified factors associated with medically serious suicide attempts (requiring medical hospitalization). METHOD: Demographic information, current psychiatric mental state, suicide attempt and psychiatric history characteristics, and DSM-IV diagnoses were compared between 65 patients hospitalized for a medically serious suicide attempt (MSSA) and 32 patients seen in the emergency room for suicide attempt but not medically hospitalized (NMSSA). RESULTS: Those with MSSAs had a higher rate of substance-induced mood disorder (but not substance abuse or dependence), while those with NMSSA had more attempts, more years since first attempt, and a higher rate of sexual and physical abuse, traumatic life events, borderline personality disorder, and bipolar disorder. CONCLUSION: Substance-induced mood disorder is an important diagnosis in the evaluation of suicidal patients. The vulnerability of mood effects caused by substance abuse may lead to a more serious suicide attempt despite less extensive psychiatric problems. The most important early psychiatric intervention may be the immediate recognition and aggressive treatment of an individual's affective and substance use disorders.

The crime of saving lives. The FDA, John Najarian, and Minnesota ALG.

The indictment of John Najarian, MD, and Richard Condie at Minneapolis, Minn, on April 10, 1995, was a defining episode in the prolonged agony that has ensued since August 1992, when the federal Food and Drug Administration (FDA) placed Minnesota Anti-Lymphocyte Globulin (MALG) on clinical hold, bringing to an end its use as an immunosuppressive agent for patients undergoing transplantation. The principal charge in the indictment is that from about 1968 until 1992--the whole period of the development and use of MALG--Dr Najarian and Mr Condie conspired to defraud the United States by impeding the FDA in its oversight of biological drugs and that they did so for the purpose of financial gain. If the charges can be considered seriously, they mean that Dr Najarian's purpose in the development and manufacture of MALG was to make money, presumably for himself, and that the possible benefit of MALG to the patients was of secondary concern to him. Several difficulties arise immediately. In 1968, MALG offered a promising new approach to immunosuppression. In a relatively crude form, it had been used at the University of Colorado with striking improvement in the survival of patients undergoing transplantation and transplanted organs, but it was painful to administer by intramuscular injections and, in addition to other side effects, produced muscular spasms. Dr Najarian and his colleagues succeeded in purifying MALG so that the pure globulin could be injected into a central vein. The process of purification was complicated and expensive, so it was hardly practical for each transplant center to produce MALG for itself. Thus, in 1969, when Dr Najarian submitted an investigational new drug application (IND) to the FDA, he stated that his purpose was to manufacture MALG not only for patients at the University of Minnesota Hospital but also for patients at other transplant centers, which were not in a position to make it for themselves. He asked the FDA to approve recovery of the cost of providing MALG to other institutions. The FDA approved Dr Najarian's IND application early in 1970 but did not respond to his request for cost recovery--then, or for the next 15 years. Dr Najarian was free to manufacture MALG and to distribute it to other transplant centers for investigational use, but as for paying for it, that was his problem. The FDA offered no suggestion.

Dawn simulation treatment of winter depression: a controlled study.

OBJECTIVE: This study sought to determine whether dawn simulation was superior to a shorter dimmer "placebo" dawn signal in treating winter depression. METHOD: In a randomized, parallel design, 22 patients with winter depression were treated with either 1 week of a 2-hour dawn simulation peaking at 250 lux or 1 week of a 30-minute dawn simulation peaking at 0.2 lux. The subjects were told that they would receive either a "gradual" dawn or a "rapid" dawn reaching an intensity that would be dimmer than standard bright light treatment. At the end of both the baseline week and the treatment week, subjects were assessed in a blind manner with the Hamilton Rating Scale for Depression. Analysis of covariance was used to compare the two dawn treatments. RESULTS: The 2-hour, 250-lux dawn simulation resulted in Hamilton depression scale scores that were significantly lower than scores after the 30-minute, 0.2-lux dawn simulation. CONCLUSIONS: This study indicates that dawn simulation is an effective treatment for winter depression.

Diagnosis of severely ill inpatients in China. A collaborative project using the structured clinical interview for DSM-III (SCID).

The purpose of this project was to investigate any differences in diagnostic practice between Chinese psychiatry and Western psychiatry with regard to severe psychiatric illness among Chinese inpatients. Specifically, the project aimed to look at differences between the Chinese diagnostic system and DSM-III. This study stemmed partly from a desire to investigate the supposed "overdiagnosis" of schizophrenia in China relative to the West. A second objective was to use a structured interview format to obtain clinical data for DSM-III and to decide whether a translated version of such an interview offered promise for future transcultural psychiatric research. Forty-two inpatients on a psychiatric ward in China were interviewed by an American psychiatrist assisted by a Chinese faculty translator and a diagnosis was made using the Structured Clinical Interview for DSM-III. A Chinese professor of psychiatry who was blind to the structured interview results interviewed each patient independently and assigned a diagnosis within the current Chinese system. Follow-up data was obtained on 69% of the patients after 16 months to check for stability of diagnosis. Results of the study pointed to less diagnostic disagreement than previous work had predicted. On cases where there was disagreement, DSM-III diagnoses tended toward affective disorders or atypical forms of psychosis while the Chinese diagnosis tended towards schizophrenia.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative efficacy of propranolol, chlordiazepoxide, and placebo in the treatment of anxiety: a double-blind trial.

The efficacy and safety of propranolol in the treatment of anxiety was compared with those of chlordiazepoxide and placebo in a 3-week, double-blind study of 212 patients. After a 1-week, single-blind placebo-washout period, patients were randomized to receive either propranolol (80, 160, or 320 mg/day), chlordiazepoxide (30, 45, or 75 mg/day), or placebo. Patients were evaluated by three physician-rated scales--Hamilton Rating Scale for Anxiety (HAM-A), Covi Anxiety Scale (CAS), and Clinical Global Impressions scale--and two patient-rated scales--Symptoms Checklist 90 and Profile of Mood States. Patients in all groups demonstrated significant improvement in their level of anxiety at all time points compared with their baseline level. At Week 1 propranolol and chlordiazepoxide patients were significantly better than placebo patients, as measured by the HAM-A and CAS. At Week 2 only propranolol was superior to placebo, based on HAM-A and CAS scores. Fifteen patients prematurely terminated because of adverse reactions (4 taking propranolol, 4 taking placebo, and 7 taking chlordiazepoxide). The incidence of side effects was similar for the two active drugs; fatigue, drowsiness, and change in libido were significantly more frequent with chlordiazepoxide and drowsiness and indigestion were more frequent with propranolol compared with placebo.

Effect of alprazolam and diazepam on anxiety and panic attacks in panic disorder: a controlled study.

Forty-eight patients currently experiencing panic attacks were randomly assigned to double-blind treatment with alprazolam, diazepam, or placebo. Efficacy was assessed using the Hamilton Rating Scale for Anxiety and a panic attack frequency rating scale. Results indicate that the two active treatments appeared equally effective in reducing both the frequency of panic attacks and the severity of generalized anxiety when compared with placebo. Overall, these data support the use of benzodiazepines in the treatment of panic disorder.
