Increased intracranial pressure and papilledema are occasionally observed in patients harboring spinal tumors in the cervical region or at the craniocervical junction, and the mechanical obstruction to the cerebrospinal fluid circulation is assumed to be responsible for such symptoms and signs. However, increased intracranial pressure is very rare in spinal tumors locating in the dorso-lumbar region; only 44 such cases having been reported in the literature. Recently we saw a 58-year-old female who presented with three brief episodes of loss of consciousness associated with nausea and vomiting, progressive dementia and insomnia. Neurologic examination disclosed an early papilledema, weakness of both legs and dementia. A left carotid angiogram revealed a small aneurysm arising from C2 segment of the internal carotid artery. Right carotid and bilateral vertebral angiograms were not contributory. The aneurysm was clipped at the first operation. The aneurysm was found apparently unruptured. A ventriculoperitoneal shunt failed to improve her dementia. Finally, a total myelographic block was found at L1 level, and a neurinoma arising from the right D12 was removed. After this, all symptoms and signs disappeared within 3 weeks. Pertinent literature on the low spinal cord tumor associated with an intracranial pressure was reviewed and the mechanism of the elevation of intracranial pressure in such cases were discussed.

A total of 61 patients with recurrent or persistent clinically measurable platin-resistant epithelial ovarian carcinoma were treated with 260 mg/m2 oral hexamethylmelamine daily for 14 days, repeated at 4-week intervals. Platin resistance was defined as progression or stable disease during cis- or carboplatin treatment (used alone or in combination with other drugs), or relapse within 6 months after the end of that therapy. Fifty patients were evaluable for response and 57 for toxicity. The objective response rate was 14% (3 complete and 4 partial responses). The response rate was higher in patients with relapse within 6 months than in patients with progression or stable disease on platin-based therapy. This observation underscores the importance of defining response and time to progression after first-line chemotherapy. The median duration of response was 8 months and the median survival in responding patients was 9+ months versus 5 months for patients with progression on hexamethylmelamine. Nausea and vomiting requiring antiemetic treatment occurred in 8 (14%) patients and reversible peripheral neuropathy in 3 patients. Two patients developed agitation, insomnia, and depression during hexamethylmelamine therapy. In conclusion, the 14% objective response rate and the occurrence of complete responses with oral hexamethylmelamine treatment in a group of ovarian cancer patients with true platin resistance are noteworthy.

Fifty-four patients with advanced malignancies were treated on this phase I trial of coumarin and cimetidine. The dose of coumarin was escalated, with three patients treated at each dose level, while the cimetidine dose was held constant at 300 mg four times daily. Patients received coumarin alone as a single daily oral dose for 14 days; on day 15, cimetidine was added and both drugs were continued until progression of disease. This trial was initiated with patients receiving coumarin at 400 mg daily and closed at 7 g daily with four of five patients on this dose experiencing nausea and vomiting. Treatment was generally well tolerated over a wide range of coumarin doses. Symptomatic side effects were few, mild, and usually self limited. Side effects included insomnia, nausea, vomiting, diarrhea, and dizziness. Two patients withdrew from therapy because of daily nausea and vomiting. Typically, nausea, vomiting, and dizziness occurred 2.5-3 hours after a dose of coumarin. In most patients, these side effects abated spontaneously with continuation of therapy. There was no significant hematologic or renal toxicity. Hepatotoxicity occurred in only one patient and was manifested by asymptomatic abnormal elevations of serum hepatic transaminases. This toxicity was reversible upon interruption of therapy. Objective tumor regressions were observed in six patients with renal cell carcinoma. Responses occurred at coumarin doses ranging from 600 mg to 5 g daily. Coumarin is a relatively nontoxic, oral, outpatient therapy that warrants further investigations for the treatment of human malignancies. Because of its low toxicity, there is potential for combining coumarin with chemotherapeutic and/or biological agents in an attempt to improve on efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of metoclopramide-induced neuroleptic malignant syndrome with cerebrospinal fluid (CSF) lactic acidosis was reported. A 44-year-old Japanese woman noted tarry stool on July 2, 1988 and was treated with metoclopramide and cimetidine for nausea and vomiting. Hydroxyzine pamoate was also administered for insomnia at 3:10 am and she became comatose with muscle rigidity at 3:40-4:30 am on July 3. Tachycardia and high fever (39.5 degrees C) were evident at 8:00 am on July 4. She was transferred to the Kyushu University Hospital. On admission, serum creatine kinase was elevated to 1640 IU/1; MM fraction was 100%. She was diagnosed as malignant syndrome. Cerebrospinal fluid was normocellular with protein 38 mg/dl and glucose 122 mg/dl. Cerebrospinal fluid lactate increased markedly to 3.43 mmol/l, CSF pH was 7.264, HCO3- 14.4 mEq/l, indicating CSF metabolic acidosis. She became afebrile after the 10th hospital day, and gradually but completely recovered within a month. She was discharged on August 16, 1988. The anti-dopaminergic activity of metoclopramide was considered to be primarily responsible for the development of malignant syndrome in this case. Cerebrospinal fluid lactic acidosis seemed to reflect hyperpyrexia or malignant syndrome induced derangement of the brain metabolism.

Fifty Thai patients with Parkinson's disease of all staging were allocated for 10 mg/day L-deprenyl therapy as the monotherapy (6 patients) and adjunctive therapy for at least two months. The assessment of this open study included the activities of daily living using Schwab/England Scale, Hoehn and Yahr staging and Unified Parkinson Disease Rating Scale (UPDRS) by comparison of the initial and after two month of treatment scores. There was improvement of both Schwab/England Scale and UPDRS in Hoehn and Yahr stage I, II and III patients. In stage IV and V patients there was no benefit of L-deprenyl therapy of both clinical and statistical analyses. Adverse effects of L-deprenyl were not serious. There were dry mouth (20%), anorexia (10%), nausea and vomiting (8%), insomnia (6%), lightheadedness (4%) constipation (4%), abdominal pain (2%), generalised ache (2%). We conclude that L-deprenyl therapy is effective, safe, but costly. It is more effective in early Parkinsonism. The effectiveness of L-deprenyl is less in more advanced states of Parkinson's disease. Thus, selection of the appropriate Parkinsonian patient for L-deprenyl therapy is vital.

A randomly selected clinic population of 400 pregnant women in Ile-Ife, Nigeria, were interviewed for complaints of psychological disorders during the last trimester of pregnancy and the post-partum period. The study shows a considerable degree of psychological disturbances during pregnancy which later decreased significantly during the post-partum. While the complaints of worrying, guilt-feeling, nausea and vomiting and "heat in-the-head", were significantly more common in younger women, insomnia and anorexia were more common in older women. The incidence of psychological complaints among the women decreased with increasing parity. There was no significant difference in the incidence between women with monogamous and polygamous marriages.

The majority of patients receiving cisplatin at a dose of 120 mg/m2 experience delayed nausea and vomiting occurring between 24 and 120 hours after chemotherapy administration. Ninety-one patients who were receiving cisplatin (120 mg/m2) as initial chemotherapy were entered into this double-blind trial. All patients received intravenous (IV) metoclopramide, dexamethasone, and lorazepam for the control of acute emesis during the period from 0 to 24 hours after cisplatin. Patients were then randomized to one of three treatment regimens: placebo; oral dexamethasone, 8 mg twice daily for two days, then 4 mg twice daily for two days; or the combination of oral metoclopramide, 0.5 mg/kg four times daily for four days, plus oral dexamethasone administered as above. Forty-eight percent of individuals who received the two-drug combination of metoclopramide plus dexamethasone experienced delayed vomiting as opposed to 65% who were administered dexamethasone alone and 89% who received placebo (P = .006). Scores assessing the severity of delayed nausea and vomiting were consistently worse in individuals receiving placebo. The incidences of sleepiness, restlessness, heartburn, hiccoughs, loose bowel movements, insomnia, and acute dystonic reactions did not differ significantly among the three regimens and were mild and self-limited. The two-drug combination of oral metoclopramide plus dexamethasone is well tolerated, safe, and more effective than dexamethasone alone or placebo in controlling delayed vomiting following cisplatin.

A double-blind randomized cross-over trial of dexamethasone and prochlorperazine as adjunctive anti-emetics with cancer chemotherapy was undertaken. The drugs were compared for cisplatin, doxorubicin and several other chemotherapy regimens. A total of 44 eligible patients were analysed. Assessment was made by questionnaire answered by the patient 24 h after the chemotherapy. The parameters compared were period of time for nausea and vomiting, number of vomiting episodes, degree of somnolence and insomnia and overall preference. In all cases there was no significant difference for either drug in its ability to suppress emetic effects. Neither drug gave adequate protection against cisplatin-containing regimens. We conclude that dexamethasone alone is equivalent to the more standard dopamine antagonists.

Hexamethylene bisacetamide (HMBA), a potent differentiating agent, was administered to patients with refractory malignant tumors. Thirteen patients received 30 evaluable courses. HMBA was given by continuous i.v. infusion for 5 days. Therapy was repeated every 28 days, if patients had recovered from toxicity. The starting dose was 24 g/m2/day. Because our previous trial had shown wide interpatient variability in HMBA pharmacokinetics and excess toxicity at HMBA plasma concentrations greater than 2 mM (HMBA doses between 24 and 33.6 g/m2/day), we attempted to individualize each patient's dose based on a dosing scheme using an adaptive (feedback) control algorithm, which assumed linear clearance for HMBA. In all courses, a plasma sample was assayed daily and infusion rates were adjusted to achieve an HMBA plasma concentration of 1.5-2.0 mM (300-400 mg/liter). The patients included 12 men and 1 woman with a median age of 56 years (range, 34-76) and median Karnofsky performance status of 90% (range, 60-100). All patients had received prior chemotherapy and 9 patients had also received radiation therapy. The linear adaptive control algorithm was reasonably precise, with a mean absolute error of 0.28 (SE 0.04) mM. However, adjustments in infusion rate systematically overshot the desired change in steady state concentration, probably due to nonlinear clearance of HMBA. For levels within 24 h of a change in infusion rate, this resulted in significant bias, with a mean error of 0.24 (SE 0.09) mM. The mean absolute error was 0.40 (SE 0.06) mM. A second adaptive control algorithm, using a pharmacokinetic model with parallel first-order (renal) clearance and Michaelis-Menten (nonrenal) clearance and using Bayesian parameter estimation with a priori estimates based on our previous phase I trial, proved to be much more precise than the linear method and was unbiased when applied retrospectively to the same observations, with a mean error (within 24 h of a change in infusion rate) of 0.02 (SE 0.06) mM and a mean absolute error of 0.22 (SE 0.03) mM. Toxicity was reversible in all cases. Neurotoxicity, consisting of hallucinations, agitation, somnolence, or confusion, was seen in 2 patients. Four patients complained of insomnia or anxiety. Mild asymptomatic acidosis was seen in 3 patients. Other toxicity included grade 1-2 nausea and vomiting (10 patients), grade 2 diarrhea (2 patients), grade 3 thrombocytopenia (3 patients), grade 1-3 leukopenia (3 patients), and oral herpes simplex infection (4 patients). Mild reversible renal insufficiency (measured by creatinine clearance) was seen in 8 patients.(ABSTRACT TRUNCATED AT 400 WORDS)

We have reviewed the therapeutic effects of benzodiazepines employed as adjuncts to cancer treatment. These agents have been used primarily for alleviating or attenuating situational anxiety, insomnia, chemotherapy-induced nausea and vomiting, and anticipatory nausea and vomiting. Situational anxiety not corrected by psychosocial support, symptom control, or time may be successfully treated with benzodiazepines. Procedure-related anxiety, for example, that related to bone marrow biopsy, venipuncture, intrathecal therapy, and the insertion of subclavian and femoral catheters, is a serious problem that may be alleviated by the use of benzodiazepines. Insomnia not caused by a depression serious enough to warrant treatment with a tricyclic antidepressant also may be successfully treated with benzodiazepines. Many clinicians have found benzodiazepines to be useful adjuncts to a cancer chemotherapy regimen because of their anxiolytic, sedative, and amnesic properties and also because of their suspected antiemetic properties when these drugs are used in conjunction with known antiemetic agents. The ability of lorazepam to induce antegrade amnesia has proved particularly useful in alleviating anticipatory nausea and vomiting connected with repeated courses of cytotoxic chemotherapy. Furthermore, since benzodiazepines are relatively safe drugs, their continued and probably expanded uses as cancer therapy adjuncts can be anticipated.
