Substance P-like and somatostatin-like immunoreactivities (SPLI and SLI) were determined in ventricular fluid of patients with chronic pain syndromes and in a comparison group with multiple sclerosis, essential tremor, epilepsy and postanoxic myoclonus. Concentrations of SPLI and SLI were non-significantly decreased by 40% and 33% in chronic pain patients as compared with control patients without pain. There were no differences apparent between subgroups of pain patients (deafferentation pain, neoplasia-induced pain, thalamic pain). High pressure liquid chromatography combined with radioimmunoassay showed marked heterogeneity of SPLI and SLI.

Carcinoembryonic antigen (CEA) was highly effectively extracted with phosphatidylinositol-specific phospholipase C (PI-PLC) from various source materials. The yield of CEA was, in some cases, 20-30 times more than that obtained by the usual method with perchloric acid. Addition of 0.1-0.2 units of PI-PLC to 1 g tumor tissue and incubation at 37 degrees C for 1 h with continuous shaking seem to be practically sufficient for CEA extraction. A simple purification procedure for CEA after extraction with PI-PLC is proposed. The immunochemical properties of CEA thus obtained were found to be identical to those of CEA obtained by the usual method.

Fourteen patients with metastatic renal cell carcinoma (RCC) were treated by systemic administration of autologous lymphokine-activated killer (LAK) cells and interleukin-2 (IL-2). Pulmonary metastases alone were found in 9 cases, pulmonary and mediastinal nodal metastases in 3, and pulmonary and bone metastases in 2. LAK cells, generated by incubation in 2 units/ml of IL 2 for 3-4 days, were intravenously administered once or twice a week. In addition, beginning on the day of the first LAK cell infusion, 1000 units of IL 2 diluted in normal saline were intravenously infused once or twice a day with occasional supplementation of 1000 units of IL-2 on each day of LAK cell infusion. The total number of LAK cells and total amount of IL-2 administered per patient in this study ranged from 0.8 x 10(10) to 6.9 x 10(10) cells and from 3.3 x 10(4) to 21.4 x 10(4) units, respectively. As toxic effects caused by the infusion of LAK cells, headache, shaking chills, fever and leukocytosis were found in all 14 cases. Side effects possibly induced by IL-2 infusion were tolerable fever, fluid retention (body weight gain of 2-3 kg) and eosinophilia. No objective regression of mediastinal nodal or bone metastases was observed. In regard to lung metastases, however, partial and minor responses were observed in 3 and 2 cases, respectively. One of the 3 patients with a partial response was clinically free of disease after undergoing a thoracotomy for resection of residual lesions, but a brain metastasis was detected 10 months after the thoracotomy. The remaining 2 patients are being closely followed up at present. In 3 of 11 patients who showed a minor response, no change or progressive disease, brain metastases were observed during or after the immunotherapy. Furthermore, we examined the possibility of selection of suitable candidates for this therapy on the basis of the degree of in vitro LAK activity against autologous cultured tumor cells in 6 patients, but there was no significant correlation between in vitro autologous tumor cell lysis by LAK cells and the clinical response to immunotherapy. In conclusion, although a complete response could not be obtained, it can be said that this immunotherapy may be effective against RCC, in particular lung metastases, since a partial response was achieved in 3 of 14 patients. However, it should be taken into consideration that this immunotherapeutic approach may have a risk of increasing the frequency of brain metastases.

A 42-year-old woman suffered unexplained weight loss followed by action tremor and difficulty initiating gait. Three months after onset of symptoms, infiltrating ductal carcinoma of the breast, metastatic to liver and lymph nodes, was diagnosed and treated briefly with cyclophosphamide, methotrexate, and 5-flourouracil (5FU). Severe symmetric action and postural tremor with a myoclonic component developed, with minimal rest tremor, severe dysarthria and dysphagia, small-stepped and slightly ataxic gait progressing to a bedbound state, and severe widespread dystonic posturing. The latter began as a typical parkinsonian posture of trunk and upper extremities and progressed to a fixed and painful flexion of the elbows and wrists and extension of fingers and neck. Sinemet, anticholinergics, baclofen, diazepam, and plasmapheresis gave no benefit. The patient died of complications of immobility 5 months after neurologic symptom onset. Autopsy revealed many pigment-laden macrophages in substantia nigra and moderate loss of pigmented neurons. Inflammation, Lewy bodies, and tumor were absent. Cerebellar Purkinje cells were moderately depleted. Mild neuronal loss and gliosis were present in globus pallidus and cerebellar cortex. Stains for anti-human IgG, IgM, kappa, and lambda were negative. This, to our knowledge, is the first report of paraneoplastic degeneration of substantia nigra or paraneoplastic parkinsonism.

Mitoxantrone is a new effective antineoplastic agent with activity against a wide range of tumors. Compared with the anthracycline drugs doxo- and daunorubicin, it exhibits a clearly lower toxicity and, most importantly, a reduced cardiotoxicity. The analysis of the side-effects recorded after accidental overdosage of the drug gives additional insight into its tolerability. Here we describe our observations in three patients who inadvertently received 100 mg m-2 (two pts) and 183 mg m-2 (one pt) as single slow bolus injections. The main side-effects were moderate nausea and vomiting, shaking chills, and profound but reversible neutro- and thrombocytopenia. There was no immediate cardiac toxicity. One patient with extensive previous daunomycin exposure developed congestive heart failure after 4 months. Two patients were not evaluable for late cardiac complications because of early death due to tumor progression.

Use of microrecording technique in stereotactic selective thalamotomy, and in stereotactic biopsy for deep-seated lesions and in tumor removal was briefly described. For selective thalamotomy, the microrecording gives ample information to delineate thalamic subnuclei. Thus, the ventrointermedius (Vim) nucleus is identified by high-amplitude background activity and large-spike discharge, some of which responds solely to contralateral natural stimuli of kinesthetic modality. A small coagulation including this thalamic Vim point resulted in permanent arrest of the various kinds of tremor. As the normal brain tissue, whether the gray or white matter, is electrically active, the microrecording is useful to delineate the brain tumor from its surroundings. Stereotactic diagnostic biopsy and removal of the brain tumor were facilitated by this adjuvant method.

A 22-year old man with a goiter and clinical manifestations of mild thyrotoxicosis (finger tremor, palpitation, tachycardia) was diagnosed as a syndrome of inappropriate secretion of TSH. Serum concentrations of T4, free T4, T3 and TSH were 24.1 micrograms/100 ml, 4.07 ng/100 ml, 261 ng/100 ml and 1.72 microU/ml, respectively. Thyroidal 131I uptake at 24 hr was 80%. The BMR was within the normal range. He had a normal TSH response to TRH (500 micrograms) with a peak level of 23.8 microU/ml. The basal level of alpha-subunit of TSH was not elevated (0.35 ng/ml). Oral 1-T3 administration (75 and 150 micrograms daily) raised serum T3 concentration, reduced basal TSH and blunted TSH response to TRH. The diurnal variation of TSH was maintained. There was no evidence of abnormalities in the secretion of other pituitary hormones. These findings were compatible with thyroid hormone resistance. However, the presence of a microadenoma in the pituitary gland was suspected with CT scan. Bilateral and simultaneous venous sampling for TSH from inferior petrosal sinus showed no gradient in TSH concentration indicating that a TSH secreting pituitary tumor was unlikely. These data suggest that inappropriate TSH secretion in the present patient is resulted from resistance to thyroid hormone. In the present study selective venous sampling is useful to differentiate the thyroid hormone resistance from a TSH secreting tumor.

A woman with sustained hypertension, facial roundness, hirsutism, marked sweating, and generalized tremor was found to have a right adrenal pheochromocytoma. Elevated levels of serum cortisol, plasma ACTH, and serum catecholamines returned to normal after the tumor was removed. It was confirmed that enzymatically dispersed tumor cells produced ACTH and catecholamines concomitantly during in vitro incubation.

Groups of Alpk:AP (Wistar-derived) rats were fed diets containing 0, 500, 1000 or 2500 ppm permethrin for 2 years and Swiss-derived mice were maintained for their lifetime (80% mortality) on diets containing 0, 250, 1000, or 2500 ppm permethrin. Changes of toxicological significance were confined to the top dose level of 2500 ppm permethrin in both species. Tremors and hypersensitivity to noise were noted in rats at this dose during the first 2 weeks of study but such signs were not seen in mice. Pathological examination of the central and peripheral nervous systems did not reveal abnormalities attributable to permethrin administration. The effect on mice at 2500 ppm permethrin was shown by decreased body weight gain. Liver hypertrophy, associated with increase in liver weight, microsomal enzyme activity, and proliferation of smooth endoplasmic reticulum occurred in the rat with similar but less marked changes in the mouse. This was considered to be an adaptive response of no toxicological significance. No evidence of a carcinogenic effect was seen in the rat study. In the mouse study a slight elevation in benign lung tumor incidence in males only at 2500 ppm permethrin was observed but was not considered to represent a carcinogenic effect.

A 76-year-old female patient with a large neck lump of 15-year duration, was accompanied by palpitation and tremor. The lump was 9 x 5cm in size and the lower half of it was not palpable because the lower pole was located in the mediastinum. Physical examination revealed two enlarged lymph nodes in the right supraclavicular area. Chest X-ray film showed a coin lesion in the right lung that seemed to be a metastasis. The patient was apparently thyrotoxic with elevated serum concentrations of 15.7 micrograms/dl thyroxin and 359 ng/dl triiodothyronine. A neck scintigraphy using 123Iodine showed a thyroid hot nodule in accordance with this lesion. A total thyroidectomy with a modified neck dissection was carried out. This was followed by 131Iodine therapy. Specimen of the primary lesion weighed 147 g. Pathology of this tumor was follicular carcinoma of the thyroid. The patient was doing well 14 months after surgery. In the literature, three cases of similar hyperfunctioning thyroid carcinoma have been reported, all of which had a large primary lesion. The histological features proved to be of follicular or papillofollicular type. The treatment in these cases was administration of an antithyroid drug followed by surgical removal.
