[Metastatic spinal cord compression in patients with lung cancer].

Metastatic spinal cord compression (MSCC) is a disabling complication to cancer for which the optimal treatment of choice is not settled. An analysis was performed in patients with MSCC secondary to lung cancer in order to elucidate clinical symptoms and treatment results according to regression of neurological deficits and survival. The total series consisted of 102 retrospectively evaluated patients referred for treatment, in the Eastern part of Denmark in the period 1979-1988. Patients included 40% cases with Small Cell Carcinoma (SCLC), Adeno-carcinoma (ACL) (26%), Squamous Cell Carcinoma (SQLC) (18%) and Large Cell Carcinoma (LCC) (9%). Symptoms, clinical presentations and therapeutic results are described. The outcome of treatment depended fundamentally on the patient's neurological condition at the time of the diagnosis. All patients with SCLC who were able to walk at the time of MSCC remained ambulatory while 15% of the non-ambulatory SCLC patients regained walking ability; in non-SCLC, 95% of patients retained walking ability while 22% regained the ability to walk. No major differences in the immediate outcome of treatment between the various histological types of lung cancer as to the different treatment modalities were observed, however, 82% of the patients with non-SCLC had benefit from treatment with laminectomy followed by radiotherapy compared with either laminectomy (47%) or radiotherapy (39%) alone (p = .03, Chi-square test). The group of patients treated with laminectomy followed by radiotherapy had a better survival (median value 3.5 months, range 0-132 months) than patients treated with either laminectomy (median value 1.5 months, range 0-32 months) or radiotherapy (median value 1 month, range 0-59 months) alone (p = .03, Log-Rank test). No significant difference was observed in survival between the various histological types of lung cancer (p = .18, Log-Rank test). Despite a short survival, early diagnosis and immediate treatment is crucial, since it may preserve the gait function in 97% of lung cancer patients developing malignant spinal cord compression.

Aggression and personality: association with amino acids and monoamine metabolites.

Associations in 52 normal individuals were examined between plasma and cerebrospinal fluid (CSF) concentrations of tryptophan (Trp) and tyrosine, and concentrations of monoamine metabolites in the CSF, and scores on an aggression questionnaire, the Kinsey Institute Reaction List II, and the Eysenck Personality Questionnaire. There was a significantly positive correlation between CSF 5-hydroxyindoleacetic acid (5-HIAA) levels and extroverted aggression scores, and a significantly negative correlation between CSF 5-HIAA levels and introverted aggression scores. Males showed higher plasma Trp concentrations than females, and significantly positive correlations between plasma Trp concentrations and scores on extroverted aggression and the Eysenck E scale. Males, furthermore, showed a significantly negative correlation between CSF Trp levels and scores on the Eysenck P scale, and a significantly positive correlation between concentrations of 3-methoxy-4-hydroxy-phenylglycol in CSF and scores on moral aggression. These results suggest that central serotonin influences aggression in normal individuals through effects on personality.

The effect of tirilazad mesylate (U74006F) on cerebral oxygen consumption, and reactivity of cerebral blood flow to carbon dioxide in healthy volunteers.

BACKGROUND: The 21-aminosteroids are a series of compounds designed to inhibit lipid peroxidation in the cell, and, as such, may have cerebral protective effects. The current study was performed to evaluate the effect of a 21-aminosteroid, tirilazad mesylate (U74006F), on cerebral blood flow, metabolism, and carbon dioxide reactivity. METHODS: Using a double-blind study design, eight volunteers received tirilazad mesylate, and eight others received only vehicle. The cerebral blood flow was measured by single photon emission computerized tomography using 133Xe inhalation in the resting condition at the beginning of the study and after infusion of tirilazad mesylate (1.5 mg/kg) or vehicle. Cerebral oxygen metabolism was calculated from the cerebral blood flow and the measured cerebral arteriovenous oxygen content difference. After both of the above cerebral blood flow measurements, arterial carbon dioxide tension was decreased by voluntary hyperventilation, and, later, increased by breathing an air/carbon dioxide mixture. The relative changes in cerebral blood flow induced by the PaCO2 variations were estimated from the changes in the arteriovenous oxygen content difference. RESULTS: Blood pressure, pulse rate, and PaCO2 were similar before and after the infusion of tirilazad mesylate in both groups, and there was no difference between the groups. The cerebral blood flow and oxygen metabolism did not change after the tirilazad mesylate infusion. The slope of the regression line of relative change of estimated cerebral blood flow and PaCO2 (regression coefficients in both groups, > 0.90) was unchanged after infusion. CONCLUSIONS: Tirilazad mesylate has no effect on cerebral blood flow, cerebral oxygen metabolism, or reactivity of cerebral blood flow to carbon dioxide in healthy volunteers.

[Metastatic spinal compression syndrome. Symptoms, diagnosis, treatment and prognosis].

A retrospective study of 398 patients suffering from metastatic compression of the spinal cord or cauda equina is presented. The study comprised almost all relevant medical records of patients admitted to hospital in the eastern part of Denmark in the period 1979 through 1985. Carcinoma of the lung, prostate, breast and kidney were the most frequent primary malignancies causing spinal compression. Most patients were treated with laminectomy, or radiotherapy or with laminectomy and radiotherapy combined. The effect of the treatment was estimated by evaluation of motor function and sphincter control. Treatment with laminectomy followed by radiotherapy was significantly superior to treatment with laminectomy or radiotherapy alone. But if the patients' motor function and primary tumour were taken into account, no significant difference between the treatments was observed. The efficacy of treatment depended upon the symptoms when the diagnosis was established, and accordingly early diagnosis is of the utmost importance. The incidence of metastatic compression increased during the period covered by the study, and since this condition must not go untreated, awareness of the symptoms, primarily pain, is essential.

Metastatic epidural spinal cord compression. Results of treatment and survival.

All medical records of patients treated for metastatic compression of the spinal cord or cauda equina in the eastern part of Denmark from 1979 through 1985 were reviewed. With regard to treatment response and survival, 345 patients could be evaluated. Carcinoma of the lung (19%), prostate (18%), breast (13%), and kidney (10%) were the most frequent primary malignancies causing spinal compression. The outcome of treatment depended primarily on the patients' condition at the time of diagnosis: 79% of the patients who were able to walk before the treatment remained ambulatory, whereas only 21% of the nonambulatory paraplegic patients and 6% of the paralytic patients regained walking ability. Patients treated with laminectomy followed by radiotherapy seemed to respond better than patients treated with radiotherapy or laminectomy alone, but when the patients' pretreatment motor function was taken into account no significant difference was found between the three forms of treatment. In the subgroup of nonambulatory patients, however, a significantly better restoration of gait was observed in patients treated with the combination of laminectomy and radiotherapy than in patients treated with radiotherapy alone. A longer survival in the group treated with the combination of laminectomy and radiotherapy may reflect that these patients were in a lower stage of disease and thus had a better potential of regaining motor function. The results call for prospective randomized studies.

Metastatic spinal cord compression. Occurrence, symptoms, clinical presentations and prognosis in 398 patients with spinal cord compression.

We reviewed all medical records concerning patients suffering from spinal cord or cauda equina compression (SCC) secondary to cancer, in the eastern part of Denmark, from 1979 through 1985. During the period the incidence of SCC in cancer patients went up from 4.4% to 6%. However, this increase was not significant. The series comprised 398 cases, with carcinoma of the prostate (19%), lung (18%), breast (14%) and kidney (10%) accounting for 61%. The symptoms were evaluated in accordance with the patients rating of pain, motor deficits, sphincter control and paraesthesia, whereas the clinical manifestations were classified on the basis of motor deficit and bladder dysfunction. During the period preceding the diagnosis of SCC, 83% of the patients suffered from back pain, 67% from deteriorating gait and 48% had retention of the urine. In 35% of the patients there was no sphincter disturbance and 10% had normal sensory function. The outcome of treatment was estimated by changes in motor deficits and sphincter function, and depended primarily on the patients condition at the time of the diagnosis. Of the patients who were able to walk before treatment, 79% remained ambulatory, whereas only 18% of the non-ambulatory patients regained walking ability. Patients treated by decompressive laminectomy followed by radiotherapy apparently had a better response than patients treated with surgery or irradiation alone, but when the patients pre-treatment motor function was taken into account, no significant difference was observed. The study may call for a properly randomized trial with careful stratification of tumour biology, performance status and neurological deficits.

Anosmia following operation for cerebral aneurysms in the anterior circulation.

Damage to the olfactory nerve during frontotemporal approach to the basal cisternal region has not previously been investigated in a quantified manner. In this retrospective study of 25 patients operated on for ruptured intracranial aneurysms via the frontotemporal route, 22 patients suffered postoperatively from anosmia ipsilateral to the side of surgery. This complication most often goes unrecognized by the patient as well as the physician, and attention should be drawn to it because of its widespread occurrence. This investigation demonstrates a high incidence of anosmia (24 (88.9%) of 27 surgical sides) occurring ipsilateral to the frontotemporal approach in aneurysm surgery. Recovery after traumatic anosmia has been recorded up to 5 years after injury. Nevertheless, the authors believe that the damage is permanent when lasting 35 months or longer.

Demodex folliculorum hominis (Simon): incidence in a normomaterial and in patients under systemic treatment with erythromycin or glucocorticoid.

A study was made of 20 cilia and sebum from 20 nasal follicles from each of 86 persons. In a normomaterial aged 20-30 years. Demodex folliculorum was present in the nasal follicles in 25% and in the cilia in 29% of the subjects. This is consistent with the very high incidence we found 10 years ago. Systemic erythromycin treatment did not erradicate the mite, but the incidence decreased in both regions. Systemic glucocorticoid treatment lowered the incidence in the nasal region, whereas the incidence increased in the ciliary region.
