We studied five patients with cerebral hemorrhage limited to the head of the caudate nucleus. This rare localization represents 11% of central nuclei hemorrhages. This entity has various clinical expressions; some are similar to a subarachnoid hemorrhage, others show the same manifestations associated with hemiparesis and neuropsychological findings, while still in others, the neuropsychological syndrome with speech, behaviour or memory disturbances predominates. Recovery depends on the patient's previous clinical status and on the presence of associated lesions at the time of hemorrhage. Typical warning signs, like headache, are often absent in the elderly and debilitated. Meningismus is explained by the intraventricular extension of the hemorrhage. Motor deficit, usually moderate, is probably due to impairment of the anterior portion of the posterior arm of the internal capsule. Destruction of the head of the left caudate nucleus, which is part of the circuit causing "subcortical aphasias", is responsible for non specific speech disturbances, that are however remarkably rich in semantic paraphasias. These dysfunctions could be caused by a "cortical diaschisis" as suggested by SPECT analysis. Memory dysfunction as a result of caudate lesion is questioned. However confusion and behavioural disturbances, like preservations, transitory mutism and self neglect, seem characteristic. As shown by cerebral blood flow (CBF) studies, these disturbances might represent a frontal dysfunction caused by the interruption of the dorso-latero-prefrontal and orbito-frontal circuits. When the hemorrhage extends beyond the head of the caudate nucleus, behavioural changes occur due to the involvement of neighbouring structures such as the thalamus, internal capsule, temporal lobe and nucleus accumbens. Caudate hemorrhages occur mostly in the elderly, often with long-standing arterial hypertension causing lesions of the lenticulo-striate arteries. Severe stenosis or complete occlusion of the middle cerebral artery with a fragile anastomotic circuit or angiopathies in younger individuals (particularly Asiatics: moyamoya disease) are less frequent, but they should be considered and investigated by arteriography. Vascular malformations are a rare cause and a relationship with amyloid angiopathy can only be suspected.

Seven patients with progressive ileal or caecal carcinoid tumors and liver metastases were treated with human recombinant alpha-interferon (IFN alfa-2b) at a dosage of 2-4 x 10(6) U daily or every other day subcutaneously. Six patients had symptoms of the carcinoid syndrome. No change of tumor size lasting 4 to 40+ months (median, 18 months) was noted in 6 patients, and 1 patient had hepatic tumor progression. A decrease in urinary excretion of 5-hydroxyindoleacetic acid by more than 50% lasting 2-11 months (median, 4) was observed in 5 patients. Four patients were completely or partially relieved of flushing, diarrhea, obstruction or abdominal pain. The side-effects were negligible with the exception of mild fever, headache and confusion only during the first days of therapy. Treatment with IFN alfa-2b offers good palliation to patients with disseminated ileal or caecal carcinoid tumor and carcinoid syndrome.

In a prospective study of 178 episodes of community-acquired native valve infective endocarditis seen at St Thomas' Hospital between 1969 and 1987, 59 patients (33 per cent) presented with neurological disorders that included meningitis, toxic confusion, major thromboembolic phenomena and headache. A neurological presentation occurred in 54 per cent of all cases of staphylococcal endocarditis, but in only 19 per cent of episodes of 'viridans' streptococcal and enterococcal endocarditis. Overall one-third of patients with staphylococcal endocarditis presented with clinical features of meningitis (40 per cent with no cardiac murmur). The mortality rate for community-acquired native valve endocarditis was higher for those with a neurological presentation than without.

We reported a case of multiple intracranial tuberculoma associated with miliary tuberculosis and reviewed the cases reported as intracranial tuberculoma in the past 11 years. A 41-year-old diabetic man was admitted to our hospital for the treatment of miliary tuberculosis and respiratory insufficiency. On admissIon, he had no neurological deficits except mild consciousness disturbance due to respiratory failure. He developed headache and mental confusion three weeks after the beginning of antituberculous therapy with isoniazid, streptomycin, rifampicin, and ethambutol. Neurological examination revealed that he had progressive right hemiparesis and was in a confusional state. Enhanced CT showed multiple intracranial nodular lesions. During 6 weeks, he had progressive neurological manifestations in spite of his initial antituberculous treatment. He responded well, however, to the chemotherapy with combination of isoniazid, kanamycin, pyrazinamide and ethionamide that were sensitive to tuberculous bacilli separated from his sputum. He became minimally right-hemiparetic by 6 weeks after the change of antituberculous medication. Serial enhanced CT scan proved to be of great value in the diagnosis and follow-up study of intracranial tuberculoma. From 1978 to 1988, there were 72 reported cases of intracranial tuberculoma in Japan; 37 were male, 32 were female and 3 were uncertain because of no detailed document. The age of onset was distributed from 6 month to 81 years in age and 2 peaks were seen in the second decade and fifth to seventh decade. Thirty-three (48%) out of 69 cases had multiple intracranial lesions. A few reports commented that neurological complications tended to appear even if they were under antituberculous therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

rTNF was administered to 28 patients with advanced metastatic cancers by continuous intravenous infusion for 5 consecutive days every 2 weeks. The dose levels were 30, 40, 70, 110, 180 and 290 micrograms/M2/day. Groups of 3 patients were started at each successive dose level and then on subsequent courses treated with the next dose level through 4 escalations as tolerated. Tumor types were: colon cancer 14; adenocarcinoma of unknown primary, 2; renal cancer, 2; leiomyosarcoma, 2; lung cancer, 1; prostate cancer, 1; thymona, 1; bladder cancer; 1; parotid, 1; Kaposi's sarcoma 2; ovarian 1. Toxicities included fever and chills (usually within the first 8 hours of infusion), fatigue, headache, decreased performance status, hypotension and CNS. All patients experienced leukopenia and thrombocytopenia within 24 hours or less after start of infusion with return of baseline by 72 hours after rTNF was stopped. The fall in these counts averaged 50% and was not dose related. No major changes in liver or renal function, coagulation or blood lipids were seen. Major dose limiting toxicities were fatigue, confusion, thrombocytopenia, seizures, hypotension and decreased performance status. NK cell activity measured against K562 target cells was augmented from about 30% target cell lysis to about 70% target cell lysis over the first 7 days of treatment. Two patients, both with metastatic colon cancer showed transient, objective tumor regression which did not qualify as a partial response. One patient with ovarian cancer had a stable partial response but progressed after 13 courses of treatment. Continuous infusion of TNF can be safely administered to patients with a maximum tolerated dose of only between 30 and 40 micrograms/M2/day.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical picture in three cases of chronic cranial pachymeningitis of unknown origin was dominated by headache, disturbed balance, a confusional state and cranial nerve lesions. The erythrocyte sedimentation rate was increased and the CSF showed inflammatory changes. CT scan imaging showed thickening of the tentorium cerebelli, which took up contrast intensely. Meningeal biopsy showed the dura-mater to be the site of a non-specific inflammatory process. No precise cause was found. Clinical manifestations in these three patients were remarkably corticosensitive but lesions did not regress on CT. The development of a state of corticodependence led to an attempt at treatment with radiotherapy and/or azathioprine, but follow up is insufficient to evaluate results.

alpha-Interferon has antitumor activity in a variety of malignancies but is frequently associated with unacceptable toxic side-effects. The routine use of agents potentially capable of reducing these side-effects has not been recommended out of concern for possible reductions in the therapeutic activity of interferon. We conducted a prospective randomized trial of alpha-interferon given with or without indomethacin to patients with malignant melanoma to determine what effect, if any, indomethacin might have on the toxic, immunomodulatory, and therapeutic properties of interferon in this disease. 53 patients were stratified according to performance status and randomized to receive alpha 2b-interferon, 20 million units per m2 i.v., 5 days per week for 4 weeks followed by 10 million units per m2 s.c. three times per week, either with or without indomethacin, 25 mg orally three times a day. The overall major response rate was 13% (three complete responders and three partial responders among 47 evaluable patients) and was the same on both arms. The mean maximal temperature elevation induced by interferon was significantly reduced (from 102.1 to 100.7, P = 0.0002) by indomethacin, but the incidence and severity of interferon-related fatigue, reduction in performance status, headache, depression, confusion, elevations in liver function tests, and myelosuppression were no different in either arm of the study. Indomethacin did not reduce the frequency of dose reductions for toxic side-effects and did not permit the administration of higher interferon doses. Peripheral blood natural killer activity was significantly enhanced in patients during maintenance therapy whether or not they received indomethacin. Indomethacin appeared to inhibit augmentation of natural killer activity during high dose induction therapy. Immunological changes did not correlate with response status. We conclude that indomethacin can reduce the fever associated with interferon therapy in patients with malignant melanoma without interfering with its therapeutic or chronic immunomodulatory activities. Since fever is rarely the dose-limiting toxicity of interferon, indomethacin is of marginal benefit to patients with malignant melanoma receiving interferon at the doses outlined in this study.

Type II altitude-related decompression sickness (DCS), due to its wide spectrum of symptoms, is often difficult to diagnose. This difficulty sometimes leads unnecessarily to the permanent grounding of an experienced aviator. So that this condition could be better understood, a total of 133 cases of Type II altitude DCS (on file at the United States Air Force Hyperbaric Medicine Division, School of Aerospace Medicine, Brooks AFB, TX) were reviewed. Most cases (94.7%) followed altitude chamber training. The most common manifestation was joint pain (43.6%), associated with headache (42.1%), visual disturbances (30.1%), and limb paresthesia (27.8%). The next most common symptoms were, in order of decreasing frequency: mental confusion (24.8%), limb numbness (16.5%), and extreme fatigue (10.5%). Spinal cord involvement, chokes, and unconsciousness were rare (6.9%, 6%, and 1.5%, respectively). Hyperbaric oxygen treatment produced fully successful results in 97.7% of the cases. Only 2.3% of the cases resulted in residual deficit; no deaths occurred. A thorough knowledge of the differential diagnosis and predisposing factors is essential to narrow the margins of error in the diagnosis and prevention of decompression sickness in the operational or training environment. A recommendation for favorable consideration of waiver action for those aviators who suffered Type II DCS is presented. These recommendations are based on a unique classification of the severity of symptoms.

Migraine in children is diagnosed in presence of paroxystic episodes of headache which recur with free intervals, provided intracranial diseases are excluded. Pathogenesis of this disorder is unclear; migraine with and migraine without aura may be different entities. Many factors can precipitate a migraine attack. In school age, psychologic stress is the commonest factor. Main characteristics of attacks in children are headache, which may be hemicranial; nausea and vomiting, abdominal pain, paraesthesiae. Scotomata are not very common in the pediatric age. In some cases, migraine attacks are complicated by sensory or motor symptoms (paraesthesiae, paresis), usually at one hemisoma. In the basilar artery migraine syndrome, features of brain-stem dysfunction predominate. In a few patients a migraine attack presents itself as an acute confusional state. In migraine, EEG abnormalities are frequent (predominance of diffuse or focal slowing). In some cases a CSF pleocytosis is found after an attack of complex migraine. Prognosis is good. Preventive treatment is necessary if the attacks are severe and if they cannot be relieved by rest or sleep. Symptomatic headaches may be produced by a variety of causes. Rarely, it is secondary to increased intracranial pressure. In the great majority of cases recurrent headache is due to migraine. Usually, clinical data are sufficient for diagnosis, though in some cases the diagnosis is difficult and it is necessary to perform laboratory examinations in order to exclude symptomatic headache.

A 32-year-old black man from rural southeastern Texas had headache, fever, chills, bronchopneumonia, and an atypical rash, complicated by hypotension, lethargy, confusion, liver dysfunction, thrombocytopenia, and acute renal failure. The diagnosis of Rocky Mountain spotted fever (RMSF) was not suspected until eight days after the onset of symptoms. He was subsequently treated with chloramphenicol, followed by hemodialysis and aggressive supportive therapy. He recovered uneventfully with complete return of renal function. This case emphasizes that RMSF should be considered in the differential diagnosis of any obscure febrile illness even in nonendemic areas.
