A cognitive-behavioral therapy for sleep-maintenance insomnia in older adults.

Older adults (3 men, 4 women, aged 55 to 68 years) with chronic sleep-maintenance insomnia were treated sequentially with relaxation therapy (RT) and then with a cognitive-behavioral therapy (CBT) specifically designed for alleviating sleep maintenance problems. Sleep diaries and an objective measure of sleep, the sleep assessment device, showed only modest improvements in measures of wake time after sleep onset, sleep efficiency, and night-to-night sleep variability following RT. However, significant improvements in these measures were observed following CBT and at a 3-month follow-up. These findings, considered in conjunction with previous reports, suggest that CBT specifically addresses factors that sustain sleep maintenance complaints. Additional trials of CBT with larger samples are warranted.

Comparative behavioral effects of clorgyline and pargyline in man: a preliminary evaluation.

The antidepressant and other behavioral effects of clorgyline, a preferential inhibitor of monoamine oxidase (MAO) type A, were compared with those of pargyline, a preferential inhibitor of MAO type B, in 16 depressed patients. In a subgroup of more severely depressed patients, clorgyline treatment for 4 weeks resulted in significant improvement on both observer-rated and self-rated scales, while minimal changes occurred during pargyline treatment. Similarly, in a crossover study that included 8 patients examined with multiple scales, clorgyline had generally greater antidepressant and antianxiety effects than did pargyline, although pargyline had some activating effects and also tended to produce more side effects. MAO type A inhibition may be more important than MAO type B inhibition for antidepressant efficacy.

Selectivity of clorgyline and pargyline as inhibitors of monoamine oxidases A and B in vivo in man.

During 4 weeks of treatment with clorgyline, a selective MAO-A inhibitor, platelet monoamine oxidase (MAO) activity was unchanged. During a similar 4-week crossover treatment period with pargyline, a selective MAO-B inhibitor, platelet MAO activity was essentially completely inhibited in the same individuals. The differential effects of the two drugs on platelet MAO, which consists exclusively of the MAO-B form, suggests that the in vitro selectivity of clorgyline, and possibly of pargyline, on MAO-A and MAO-B may be maintained in vivo during long-term administration in man. Reductions in blood pressure, heart rate, and plasma amine oxidase activity were generally similar in magnitude during treatment with both drugs, however, suggesting that either these effects are nonspecific consequences of both MAO-A and MAO-B inhibition, or that pargyline also inhibited MAO-A activity.

Sweat gland carcinoma with syringomatous features: a light microscopic and ultrastructural study.

A 76-year-old man presented with a 10-year history of a slowly enlarging lesion of his upper lip. An excisional biopsy revealed a diffusely infiltrating, well-differentiated, sweat gland carcinoma with syringomatous features. The ultrastructural characteristics corresponded to those described for benign syringoma and normal eccrine ducts. A review of the literature emphasized the extreme rarity of this lesion. Sweat gland carcinomas tend to have an indolent history but often manifest aggressive behavior at the time of clinical presentation. The preponderance of anaplastic lesions accounts for a generally unfavorable prognosis.

The central noradrenergic system and affective response to MAO inhibitors.

1. In humans, norepinephrine (NE) has been postulated to be involved in the regulation of mood and behavior and to be altered in patients with manic-depressive illness. 2. Recent methodological advances have made possible a more direct assessment of central noradrenergic activity by the accurate measurement of the small amounts of NE and of the enzyme responsible for the conversion of dopamine to NE, dopamine-beta-hydroxylase (DBH), found in cerebrospinal fluid (CSF). 3. Cerebrospinal fluid samples were obtained from depressed patients both before and after treatment with two monoamine oxidase-inhibiting antidepressant drugs, clorgyline and pargyline. 4. Patients were rated twice daily by nursing staff on a modified 15-point scale for severity of global depression and anxiety. Patients were also rated using the Hamilton depression rating scale. 5. High negative correlations were observed between the drug-related changes in CSF NE and the changes in depression ratings on both the global ratings (r = -.95, p less than .001) and the Hamilton rating scale (r = -.81, p less than .01). Changes in NE were also highly correlated with changes in global anxiety ratings (r = -.85, p less than .01) calculated on the basis of changes from baseline for each measurement. Drug-related changes in CSF DBH similarly showed negative correlations with clinical response (r = -.79, r = -.38, r = -.68 respectively). In contrast, no significant correlations were found when drug-related changes in CSF MHPG were compared to changes in clinical state.

Retinoblastoma: correlation of invasion of the optic nerve and choroid with prognosis and metastases.

The histological sections of 74 retinoblastoma patients were reviewed. The extent of optic nerve invasion was correlated with choroidal/scleral extension. Choroidal invasion carries 100% survival provided that the sclera, iris, and whole optic nerve are not also involved. Invasion of the optic nerve beyond the lamina cribrosa also carries 100% survival provided that the resection line is free and that invasion does not involve the sclera or iris. Plentiful rosettes were usually found in those tumours that had not extended beyond the choroid or as far as the resection line of the optic nerve and were therefore associated with a good prognosis. The absence of rosettes did not necessarily indicate a poor prognosis. The site of metastases was related to optic nerve and scleral/extrascleral extension. The various systems of staging retinoblastoma are compared, and a new system is proposed to cover the whole spectrum of the disease and to offer a reliable guide to prognosis and treatment.

Synergism between BCNU and irradiation in the treatment of anaplastic gliomas. An in vivo study using the avian sarcoma virus-induced glioma model.

The therapeutic effects of irradiation, BCNU, or combined irradiation and BCNU were studied in the avian sarrcoma virus (ASV)-induced glioma model in rats. Whole-head orthovoltage radiation therapy was given in six equal fractions over 2 weeks, and BCNU was administered intraperitoneally as a single dose of 10 mg/kg. Two series of experiments were performed in order to duplicate the results. In Series I, the median survival times of the experimental groups, in days after randomization were as follows: control group (no treatment), 69; group receiving 200 rads, 84 (p less than 0.05); group receiving BCNU, 80.5 (p less than 0.1); and group receiving 2000 rads + BCNU, 112 (p less than 0.001). In Series 2, the median survival times were: control group, 73.5; group receiving 2300 rads, 85 (p less than 0.01); group receiving BCNU, 92.5 (p less than 0.025); and group receiving 2300 rads + BCNU, 123.5 (p less than 0.001). In both series, combined therapy was significantly better than either radiation or BCNU alone. This is the first time that a synergistic effect of BCNU and irradiation has been reported in an in vivo brain-tumor model and supports the clinical use of this combination in the treatment of malignant gliomas.

Ultrastructure of psammoma bodies of meningioma in tissue culture.

An 8-day-old tissue culture of a human meningioma was studied by electron microscopy. Psammoma bodies were detected in all stages of evolution, affording a unique opportunity for observing the genesis of these structures. Matrix vesicles appeared instrumental in the calcification of a granular extracellular material. Although matrix vesicles are described in both physiologic and pathologic calcification, they have not been previously reported in the very few ultrastructural studies of psammoma bodies in meningiomas.

Amyloid tumor. A clinicopathologic study of four cases.

Four examples of amyloid tumors were studied to determine whether there was an association with myelomatosis. Three patients had follow-up examinations of 12 years, 9 years, and 2 1/2 years, respectively. A local recurrence developed in one patient and a second lesion developed in this patient and in one other who also had a transient monoclonal 7S globulin peak. In spite of these findings, none of our patients developed myelomatosis. A study of the scanty literature on amyloid tumors reveals that only patients with lesions of the lung and urinary bladder have had long-term follow-up. They have invariably remained free of disease. Several reports of bone lesions have inferred that amyloid tumors occurring here signify solitary myeloma despite a lack of follow-up confirmation. Our longest surviving patient developed two bone lesions over a 12-year period without developing myelomatosis. Our findings lead us to conclude that there is little evidence to regard the presence of an amyloid tumor at any site as a manifestation of solitary myeloma or myelomatosis.

Congenital saccular aneurysm in a 19-day-old neonate: case report and review of the literature.

A 19-day-old neonate presented with a massive intracranial hemorrhage which was found at autopsy to be due to a ruptured intracranial saccular aneurysm. Detailed histologic evaluation revealed that this was a true congenital lesion. A survey of the literature yielded 19 cases of saccular aneurysm in the first year of life. Together with this report, nine cases are now on record, containing sufficient histologic detail to suggest a congenital basis, contrary to the assertion casting doubt on the existence of the entity. Attention is drawn to the practical importance of recognizing this lesion as a rare cause of intracranial hemorrhage in the neonate, since successful surgical intervention has been reported in several cases.

Elevation of plasma-prolactin by monoamine-oxidase inhibitors.

Plasma-prolactin levels doubled in depressive patients treated with the monoamine-oxidase inhibitors, clorgyline and pargyline. The absence of significant changes in plasma-cortisol in the same patients suggests that the increases in prolactin are not attributable to non-specific effects of stress.

Superficial cystic gastritis with alopecia. A forme fruste of the Cronkhite-Canada syndrome.

The Cronkhite-Canada syndrome is a rare and often fatal condition. A case of superficial cystic gastritis was suspected on peroral gastric biopsy and was later confirmed at autopsy. The selective involvement of the stomach together with the presence of alopecia leads us to conclude that this case is unique and represents a forme fruste of the Cronkhite-Canada syndrome. A complicating feature was the presence of an opportunistic cytomegalovirus infection of the gastrointestinal tract and lungs.
