Olanzapine in the treatment of post-traumatic stress disorder: a pilot study.

Because the atypical antipsychotic olanzapine may be efficacious in treating post-traumatic stress disorder (PTSD) symptoms, we conducted a 10-week, double-blind, placebo-controlled evaluation in which 15 patients were randomized 2:1 to either olanzapine or placebo. The initial dosage was 5 mg/day and was titrated to a maximum of 20 mg/day. Eleven patients completed the study. Patients in both groups showed improvement in PTSD symptoms, but no between-group differences in treatment response were observed and a high placebo response rate was found. Both treatments were tolerated well, although the olanzapine treatment group had more weight gain. Olanzapine fared no better than placebo in this preliminary study in the treatment of PTSD. The lack of difference between olanzapine and placebo may in part be due to olanzapine's not being effective in PTSD or, alternatively, a small sample size, a high placebo response in certain forms of PTSD and the chronicity of PTSD symptoms in some patients.

Short-course induction chemoradiotherapy with paclitaxel for stage III non-small-cell lung cancer.

BACKGROUND: This study assessed toxicity, tumor response, disease control, and survival after short-course induction chemoradiotherapy and surgical resection in patients with stage III non-small-cell lung carcinoma. METHODS: Forty-five patients with stage III non-small-cell lung carcinoma received 12-day induction therapy of a 96-hour continuous infusion of cisplatin (20 mg/m2 per day), 24-hour infusion of paclitaxel (175 mg/m2), and concurrent accelerated fractionation radiation therapy (1.5 Gy twice daily) to a dose of 30 Gy. Surgical resection was scheduled for 4 weeks later. Postoperatively, a second identical course of chemotherapy and concurrent radiation therapy (30 to 33 Gy) was given. RESULTS: Induction toxicity resulted in hospitalization of 18 (40%) patients for neutropenic fever. No induction deaths occurred. Of 40 (89%) patients who underwent thoracotomy, resection for cure was possible in 32 (71%) patients. Pathologic response was noted in 21 (47%) patients, and 14 (31%) were downstaged to mediastinal node negative (stage 0, I, or II). At a median follow-up of 19 months, 24 patients were alive, 10 with recurrent disease. Of 21 deaths, 16 were from recurrent disease, three were from treatment, and two were unrelated. Recurrent disease was distant in 21 patients, distant and locoregional in 2, and locoregional in 3. The Kaplan-Meier projected 24-month survival is 49%. Projected 24-month survival is 61% for stage IIIA, 17% for stage IIIB (p = 0.035); 84% for pathologic responders, 22% for nonresponders (p<0.001); 83% for downstaged patients (stage 0, I, or II), 33% for those not downstaged (p = 0.005); and 63% for resectable patients, 14% for unresectable patients (p = 0.007). CONCLUSIONS: We conclude that short-course neoadjuvant therapy with paclitaxel (1) has manageable toxicity and a low treatment mortality, (2) results in good tumor response and downstaging, (3) provides excellent locoregional control with most recurrences being distant, and (4) has improved the median survival compared with historical controls. Survival was better in stage IIIA patients, resectable patients, pathologic responders, and patients downstaged to mediastinal node negative disease (stage 0, I, or II).

Antimyeloperoxidase antibodies induce neutrophil adherence to cultured human endothelial cells.

Antimyeloperoxidase autoantibodies are found in the sera of some patients with glomerulonephritis and systemic vasculitis. Previously, we demonstrated that they were able to stimulate neutrophils to damage cultured human endothelial cells. We now report that antimyeloperoxidase antibodies are able to stimulate neutrophils to adhere to cultured human endothelial cells. Immunoglobulin G purified from myeloperoxidase-antineutrophil cytoplasmic autoantibody positive sera increased adherence to 331 +/- 60% of unstimulated controls. In a similar manner, rabbit antimyeloperoxidase enhanced neutrophil adherence. Stimulating the endothelial cells with 10 micrograms/mL endotoxin enhanced antimyeloperoxidase stimulated adherence. In the presence of a CD18 blocking antibody (MoAb 60.3), antimyeloperoxidase-stimulated adherence was significantly decreased. These results add further understanding to the antimyeloperoxidase-stimulated neutrophil-endothelial cell interaction and further support the hypothesis that antimyeloperoxidase autoantibodies are of pathogenic import in glomerulonephritis and vasculitis.

Candida epiglottitis.

Acute epiglottitis is most commonly of bacterial origin. A case of Candida epiglottis in a healthy, nondebilitated patient is reported. A literature search did not produce a previously reported case.

Validity of spinal cord examination as a substitute procedure for routine rabies diagnosis.

A significant portion of specimens received by this laboratory for rabies diagnosis is unsatisfactory for testing due to decomposition of the brain, or severe mutilation of the head when the animal was killed. Examination of the spinal cord was therefore explored as a possible alternative method when standard brain examination was not possible. In this study, both brain and spinal cord of 248 rabies-suspect animals were examined to assess the reliability of the spinal cord method. Brain and spinal cord of the 248 animals were examined by fluorescent antibody (FA) method, and mouse inoculation tests were performed on 247 brain specimens and 13 spinal cord specimens. By using both brain and spinal cord, 30 animals representing 8 species were diagnosed as rabid by FA, and 218, representing 11 species, were negative. There was 100% agreement between two procedures with FA as the criterion. This study showed that in cases where the usual examination is precluded due to brain destruction, the spinal cord procedure offers an equally reliable alternate method of diagnosis.

Behavioural psychotherapy of the frontal-lobe-injured patient in an outpatient setting.

We present two cases of outpatient behavioural psychotherapy of frontal-lobe brain-injured adults. Unlike inpatient treatment of severely frontal-injured patients in which the hospital setting acts on the patient to modify behaviour, outpatient treatment teaches the self-motivated individual to use the structure and directiveness of behavioural psychotherapy to overcome his or her neuropsychological deficits. The literature describes two types of frontal syndromes: disinhibition and adynamia. Treatment of both types of syndromes is illustrated using case presentations. The therapeutic interventions for both syndromes are designed to exaggerate the link between stimulus and response to counter impaired processing of feedback. A six-stage behavioural psychotherapy model of the frontal-injured patient is outlined.
