Patients suffering from mixed anxiety/depressive reactions, referred to the out-patient department of a large psychiatric hospital, were treated with either amitriptyline tablets or fluphenazine with nortriptyline (f/n) tablets for a period of four weeks. The study utilized a double-blind, completely randomised design, and patients' progress was assessed by means of the Wing Present State Examination, the Wakefield Self-Assessment Depression Inventory, and a side effects inventory. Both the symptom rating scales showed that purely depressive symptomatology improved significantly in each treatment group, but the patients' self-ratings showed that only f/n produced a significant alleviation of anxiety symptoms and panic attacks. The patients receiving f/n rated themselves as significantly (p less than 0.05) less irritable, as well as less anxious, after 4 weeks treatment, than those receiving amitriptyline. The PSE schedule did not differentiate between the 2 treatment groups, but self-rating, which is a more sensitive method of eliciting drug effectiveness in patients suffering from mild psychiatric disorders, did demonstrate patient preference for f/n. This should have important implications for compliance with treatment.

The authors report on the effects of propranolol, a beta-adrenergic blocking agent, on 10 patients with pathological panic states. Propranolol was effective in treating acute pathological panic, but modest doses of the drug administered for brief periods of time did not alleviate chronic panic attacks associated with agoraphobia. The drug suppressed panic associated with depressive syndromes but did not affect the depression and had no clear effect on anticipatory anxiety. The authors suggest that further study of these findings may clarify other clinical problems.

Panic episodes were described as a distinct form of anxiety by Freud almost 100 years ago, and the recent publication of the Diagnostic and Statistical Manual of Mental Disorders, third edition (D.S.M.-III), has provided the basis for the separate diagnostic entity of panic disorder. In this study, we showed the historical review of research and the result of our clinical study of panic disorder in 7 patients. The following results were obtained: 1) Abnormal DSTs were observed in only two of 5 patients. 2) Five of 6 patients showed high concentration of adrenaline and noradrenaline in urine. 3) Anxiety was provoked by caffeine in two of 5 patients. 4) Depression of T-wave was shown in three of 5 patients with orthostatic E.C.G. 5) Sinus tachycardia was gained in one of 3 patients with Holter E.C.G. 6) Abnormal respiratory functions were observed in all two patients with Treadmill. 7) Only one small heart was observed on a chest radiograph. 8) Panic attacks were provoked by sodium lactate infusion in four of 7 patients.

The incidence of panic attacks methadone-maintained patients has increased over a 10-year period from 1 to 6-13%. Cocaine use appears to be associated with this increase, although other environmental and constitutional factors may be contributory. Patients with cocaine-associated panic differ from other panic patients in rates of psychiatric hospitalization and medical illness, but not in depression, other drug use, or agoraphobia.

Panic attacks occur more often in females than males with onset usually in the late 20s. A 27-year old woman who experienced a panic attach (heart palpitations, fatigue, bodily shaking, labored breathing, and feelings of terror and being out of control) after she stopped taking a combined oral contraceptive (COC) (.5 norgestrel and .05 mg ethinyl estradiol) was admitted to Osaka Medical College in Takatsuki, Japan. She experienced depression at 18 and took limited amounts of antidepressants for only 1 year. When she started taking the COC at 27, she experienced feelings of unreality and fear, hyperventilation, and heart palpitations. Laboratory results showed lower than normal levels of plasma luteinizing hormone (LH) and follicle stimulating hormone (FSH) and a low estradiol level. Yet the plasma cortisol level was much high than normal (22.5 mcg/d1 vs. 3-15.2 mcg/d1). Administration of 200 mg sulpiride/day and 1.2 mg alprazolam/day alleviated almost all symptoms. She did experience mild phobic avoidance and anxiety, however. After successful treatment in the hospital, she discharged herself. Because she was concerned that the panic attacks would recur, she was provided with information on her disorder. She agreed to continue the medication. 1 possible explanation for this case is rapid endocrinological change induced by the ingestion and stopping of the COC which in turn induced a sympatho-adrenal response (her high cortisol levels) to several simple physiological stimuli. Another possible explanation is the COC induced rapid endocrinological changes that may have brought on an anxiotropic effect in someone who had earlier experienced depression.

Immunological, neuroendocrine and psychological parameters were examined in 14 psychophysically healthy subjects and in 17 panic disorder patients before and after a 30-day course of alprazolam therapy. T lymphocyte proliferation in response to the mitogen phytohemagglutinin, lymphocyte beta-endorphin (beta-EP) concentrations, plasma ACTH, cortisol and beta-EP levels were examined in basal conditions and after corticotropin-releasing hormone (CRH) stimulation. Cortisol inhibition by dexamethasone (DST) and basal growth hormone (GH) and prolactin levels were also examined. Depression, state or trait anxiety, anticipatory anxiety, agoraphobia, simple and social phobias, severity and frequency of panic attacks were monitored by rating scales. The immune study did not reveal any significant difference between patients and controls, or any effect of alprazolam therapy. The hormonal data for the two groups were similar, except for higher than normal basal ACTH and GH plasma levels, lower than normal ratios between the ACTH and cortisol responses to CRH, and blunted DST in some patients. All the impairments improved after alprazolam therapy, in parallel with decreases in anxiety and in severity and frequency of panic attacks.

Diurnal changes in the frequency of panic attacks and symptoms of generalised anxiety, phobic anxiety and phobic avoidance in 34 panic-disorder patients and 40 normal controls were evaluated. The panic-disorder patients had significant diurnal changes in generalised and phobic anxiety, but not phobic avoidance. Increased severity of symptoms and prominent diurnal changes were most evident in the panic-disorder patients with a history of depression. Although panic attacks were distributed throughout the 24-hour period, patients with a current episode or history of depression tended to have more frequent panic attacks in the morning or early afternoon. These observations challenge the traditional belief that 'anxious neurotic' patients are relatively asymptomatic upon awakening in the morning and then develop more severe symptoms of anxiety later in the day.

We investigated the relationship between suicidality, agitation, panic attacks, and the thyrotropin-stimulating hormone (TSH) response to thyrotropin-releasing hormone (TRH), and tested the hypothesis that panic would account for the association between a reduced TSH response and the other conditions. Twenty-seven euthyroid primary unipolar depressed inpatient women received a TRH test and systematic psychiatric assessment. Panic attacks were insufficient to explain the link between the TSH response and suicidal intent, lethality, and agitation; each condition was independently associated with a lower TSH response. In an additive fashion, copresence of conditions further reduced TSH response. The symptom constellation of panic, agitation, and suicidality in depression may correlate with the greatest reduction in TSH response.

Forty-eight patients with DSM-III-R Panic Disorder underwent a hyperventilation provocation Test (HVPT). Twenty-four patients rated the symptoms induced during the HVPT as similar to those occurring during panic attacks in daily life. Contrary to the classical hyperventilation model of panic, no differences were found in respiratory physiology between recognizers and non-recognizers before and during voluntary hyperventilation. Moreover, recognizers and non-recognizers reported comparable levels of panic and hyperventilation symptoms and state anxiety during panic attacks in daily life. Ten of the recognizers also had a panic attack during the HVPT, independent of any differential CO2 alterations. Compared to non-panickers, panickers obtained higher scores for agoraphobia and depression. On the basis of these results, it is concluded that recognizers or panickers do not show a tendency towards hyperventilation, but that reports of severe panic and hyperventilation symptoms are more closely related to the level of anxiety. These results are more consistent with the cognitive model of panic, which emphasizes the patient's tendency to interpret somatic symptoms catastrophically.

The present study investigated the relationship between respiratory function, catastrophic thoughts about anxiety, and panic in 48 Chronic Obstructive Pulmonary Disease (COPD) patients. During a routine office visit which included respiratory function tests (Forced Vital Capacity, FVC; Forced Expiratory Volume--first second, FEV1) patients completed a battery of questionnaires which assessed history of panic, days with shortness of breath, general activity level, agoraphobic cognitions, perception of bodily sensations, anxiety and depression. Thirty-seven percent of the sample reported experiencing a panic attack. Subjects showed a significant impairment in respiratory functioning. Patients with a history of panic did not differ from those who had not experienced panic on demographic, physiologic, or activity variables. Patients who experienced panic reported significantly more agoraphobic cognitions and greater concern with bodily sensations than did patients who did not experience panic.
