SIR: We would like to share with your readers an incident at our hospital which points up the need for extreme care in differential diagnosis. Recently, five patients diagnosed as psychotic were admitted to our acute care psychiatric unit. Each patient was prescribed a major tranquilizer. One typical case report follows:
A 52-year-old
woman
was admitted
and diagnosed
as a
gravely disabled paranoid schizophrenic and placed on haloperidol, 5 mg t.i.d. On later questioning by a team consisting of a psychiatrist, a psychologist, a clinical pharmacist, and a social worker, she initially denied all but occasional use of alcohol. After more intense questioning, she admitted to very heavy drinking and three convictions for driving while intoxicated, one of which involved an accident in which she received a head injury. At this point all neuroleptic drugs were discontinued. The patient was placed on chlordiazepoxide, 10 mg t.i.d. and 25 mg h.s. ; thiamine, 100 mg/day; and flurazepam, 30 mg h.s. Laboratory values were normal cxcept for total protein 5.5 (normal=6.0-8.3) and globulin

SIR: Although it was timely and important, the Clinical and Research Report ‘ ‘Rapid Treatment of Delirium in Critically Ill Patients” by David P. Moore, M.D. (December 1977 issue) has left us with some inquiries and concerns. Dr.

of a supposedly

patient,
but
all we as readers know is that the patient on the eighth hospital day ‘ ‘became agitated, struck a nurse, and pulled out his nasogastric tube,’ ‘ and that ‘ ‘physical and laboratory examinations failed to reveal anything that could account for the change in the patient’s clinical state. ‘ ‘ Presumably on this basis, ‘ ‘a diagnosis of delirium of unknown etiology was made. ‘ ‘ One could assume many reasons for impulsive, inappropriate behavior. Matters important to readers are drug history, whether a drug screen was performed, which laboratory examinations were done, and the doses and durations of treatment with morphine, diazepam, and any other medications administered during the hospitalization. Both toxic and withdrawal reactions to drugs arc common causes of delirium in hospitalized patients. For example, Dysken and
Chan have reported a withdrawal reaction with delirium up to 8 days after discontinuing diazepam (1). Symptoms of alcohol withdrawal can appear as late as 10 days after abstinence commences (2). Toxic reactions to drugs with anticholinergic properties are worth mentioning because these drugs arc ubiquitous. Both morphine and diazepam, which were administered before the onset of the unusual behavior, have anticholinergic properties . Haloperidol also possesses anticholinergic effects, although they are not nearly so pronounced as those of the sedating phenothiazines, such as chlorpromazine and thioridazine. Physostigmine has been reported to be effective in treating overdoses with all compounds mentioned except alcohol and morphine (3).
Ofequal
concern
is the implication
that
patients
with
delir-
ium of unknown etiology may be treated effectively and safely with haloperidol. Certainly a delirium reflecting a toxic reaction to phenothiazines, butyrophenones, or anticholinergic compounds would not be effectively and safely
treated
with
haloperidol.
A better
conclusion
to be drawn
from this case report and a literature review is that while the etiology of a delirium, other organic brain syndrome, or any type of “cerebral insufficiency” is being sought, control of symptoms with haloperidol may be considered in manage-
ment.
Great care should be taken in the differential diagnosis of alcoholism and schizophrenia at the time of admission because there is substantial evidence that the major tranquilizers used in the treatment of psychoses can lower the seizure threshold during alcohol withdrawal and thus possibly precipitate a grand mal seizure (1). Before one prescribes a major tranquilizer for a newly admitted patient, a procedure

Men-
tal Health Clinic, an affiliate of the UCLA School of Mcdicine. In our study, 96 schizophrenic outpatients with clinically diagnosed ‘ ‘flattened’ ‘ affect were psychometrically tested using the Zung Self-Rating Depression Scale (SDS) to determine specifically whether a latent underlying depression existed in a significant number of these patients. These selected patients had denied feelings of depression and did not appear to us to be depressed. The SDS was administered to each patient. Test results clearly indicated that all subjects were experiencing moderate to severe depression. Specifically, scores for the 96 patients ranged from 54-88, with a mean of67 (SD=l3.44). Now that the existence of depression in chronic schizophrenia has ‘ ‘come out of the closet’ ‘ we would hope that clinicians will take this into account in the diagnosis and treatment of the affect as well as the thought disorder. This should improve the overall functioning of schizophrenic patients. Reprint requests or additional information concerning our study should be directed to us at the address below.

I do agree with them that suppression of symptoms may forestall diagnostic measures and, in fact, stated in my paper that ‘Optimum management of delirium includes diagnosis and treatment of the underlying cause of the cerebral insufficiency and symptomatic treatment of the delirium itself.

plete blood count, SMA-18, prothrombin time, arterial blood gases, chest X-ray, ECG; EEG, lumbar puncture, and cultures of urine, sputum, and blood. None of the measures proved enlightening. The patient’s systemic medications included only morphine and diazepam, the dosages of which had been unchanged for the 4 days before the onset of the delirium. Thus the only diagnosis I could make was delirium of unknown etiology. Drs. Cutler and Heiser’s point regarding the danger of treating delirium secondary to anticholinergics or to antipsychotics with haloperidol is well taken, and I did not mean to imply that it should be used in these conditions. However, I can think of few other conditions, with the possible cxception of withdrawal syndromes, in which it would be dangerous to use haloperidol. As I noted in my paper, “Controlled studies are needed.” My own concern with the tone of their letter is that it might lead some physicians to withhold drug treatment in a critical situation until all diagnostic studies were done. A full diagnostic workup must be done on all delirius patients, but in those who present with potentially life-threatening behavior, as was the case in the patient I described, management must be prompt and effective. Haloperidol appears, with the exceptions mentioned above, to be the drug of choice in such situations. DAVID
