The effects of continuous infusion of dobutamine 5 to 15 microgram/Kg./min. were studied in 17 patients using right heart catheterizations, echocardiography, and/or the Systolic Time Intervals. HR increase was dose-related, but insignificant (p less than 0.05) rate increase was obtained at infusion rates below 15 microgram/Kg.)min. C.O. increased from 2.9 +/- 0.7 to 5.0 +/- 1.2 liters/min. (p less than 0.001), and the stroke volume from 30 +/- 6 to 49 +/- 14 ml./min. (p less than 0.005). The mean BP did not change, P.A.W.P. decreased from 30 +/- 7 to 20 +/- 8 mm. Hg (p less than 0.001) and R.A.P. from 20.0 to 12.0 mm. Hg (p less than 0.005). The P.E.P.I. decreased from 160.93 +/- 54.91 to 133.4 +/- 28.7 msec. (p less than 0.050). Echo-determined mean VCf increased from 0.387 +/- 0.14 to 0.537 +/- 0.13 cm. (p less than 0.010), diastolic diameter did not change significantly, but the end systolic diameter decreased from 6.020 +/- 0.69 to 5.750 +/- 0.70 cm. (p less than 0.025). During a mean infusion period of 75 hours, the only side effects noted were transient nausea and/or vomiting at 15 microgram/Kg./min. dose range in two patients, and multifocal P.V.C.'s following 68 hours of infusion in another patient. It is concluded that in the dose range of 5 to 15 microgram/Kg./min., dobutamine is well tolerated and is a very potent inotropic agent with only minor effects on the heart rate and blood pressure.

Between June 1982 and July 1990, 55 patients (41 with bladder cancers and 14 with renal pelvic or ureteral cancers) who had undergone radical extirpative surgery and/or node dissection for pathological stage pT2-4 and/or nodal disease received adjuvant chemotherapy consisting of cisplatin alone or in combination with other agents. In all, 26 of the bladder-cancer patients also received preoperative chemotherapy consisting of arterial infusion of cisplatin, mitomycin C, and Adriamycin. Adjuvant chemotherapy was performed according to the following protocol. Between June 1982 and July 1987, 30-50 mg/m2 cisplatin either alone or in combination with Adriamycin and 5-fluorouracil (CAF) was given to 35 patients in an induction and maintenance setting for 1 year. After July 1987, short-course cisplatin (70 mg/m2) or cisplatin, etoposide, and Adriamycin combination chemotherapy (CVA) was given to 20 patients. Of the 55 patients, 38 are alive and show no evidence of disease, three are alive with disease, 13 have died of their disease, and 1 has died of an unrelated cause. The 5-year survival of all patients was 65.1%. The survival of the 20 patients who were treated after July 1987 was better than that of the 35 patients who were treated before June 1987. Local recurrence and/or distant dissemination occurred in 16 patients, 13 of whom died of cancer progression. Nausea and vomiting and anorexia occurred in most patients during the administration of cisplatin. Mild to moderate myelosuppression developed in patients who received CAF or CVA combination chemotherapy. Although adjuvant chemotherapy combined with radical surgery seemed to be effective in cases with a pathological stage of pT3a or less, more intensive pre- or postoperative chemotherapy is needed to improve the poor prognosis of patients with deeply invasive uroepithelial cancer.

Melanoma frequently disseminates to the gastrointestinal tract, being found post-mortem in 60 per cent of patients with disseminated disease, while during life it is diagnosed in only 4 per cent. During the period 1981-87, 835 melanoma patients were referred and 30 developed complaints caused by gastrointestinal metastatic melanoma. Twenty-three patients were treated surgically. The interval between treatment of the primary melanoma and detection of intestinal involvement was a median of 34 months (range 2-87 months). In four patients recurrence in the gut was the first evidence of dissemination. Major complaints were nausea and vomiting, abdominal pain, signs of anaemia, and blood in the stools. Complications were bleeding (ten cases), ileus due to intussusception (five cases), bowel perforation (four cases) and cholecystitis (one case). The metastases, mainly localized in the small bowel, were removed by relatively simple procedures. Symptoms were reduced in 19 patients. Two patients died after operation: one from sepsis due to suture leakage, the other from pneumonia and a cerebrovascular accident. Of the remaining patients, 16 survived a median of 7.5 (range 0.7-32.0) months. Five patients are still alive 72, 72, 70, 7 and 2 months after the metastasectomy, three of whom are tumour-free. The actuarial 5-year survival of all patients is 19 per cent. These results support surgical intervention for patients with complaints and/or complications attributable to gastrointestinal metastatic melanoma.

Two hundred and sixty-four patients were included in an open, randomized, multicenter trial, with the aim of determining whether nicardipine can be useful in the prevention of cerebral infarction. The patients had experienced one or more transient ischemic attacks, reversible ischemic neurologic defect, or stroke with minor permanent neurological deficit in the 12 months before enrolling in the study. Each patient was randomly assigned to received 250 mg of aspirin once daily plus 20 mg of nicardipine thrice daily (n = 170) or 250 mg of aspirin once daily (n = 94) for 12 months. During the 12-month treatment period, 12% of the aspirin-plus-nicardipine group and 19% of the aspirin-only group experienced an ischemic cerebrovascular event; at six months, the cumulative incidence of events was significantly lower in the aspirin-plus-nicardipine group than in the aspirin-only group. One patient in each group died of a recurrent stroke. Aspirin-related side effects were dyspepsia (reported by four patients), heartburn (by seven), nausea and vomiting (by four), and melena (by five); nicardipine-related side effects were transient hypotension (by two), headache (by four), ankle edema (by three), and constipation (by four). Results indicate that the addition of nicardipine to antiplatelet treatment may safely prevent the recurrence of ischemic cerebrovascular events.

Ten patients with pituitary apoplexy were treated at the Institute of Endocrinology, Gerontology and Geriatrics in Sofia over the last 5 years. They represented 5.06% of the total number of patients with pituitary adenomas treated at the Institute during the same period. The highest frequency of pituitary apoplexy was noted among patients with Nelson's syndrome. In 5 patients of this group pituitary apoplexy was the first sign of a tumor. Headaches combined with nausea and vomiting were the earliest symptoms of pituitary apoplexy, and ptosis and ophthalmoplegy were the most common symptoms in the patients. The disease was not correctly diagnosed in 7 patients who immediately after apoplexy were treated in neurological and ophthalmological departments.

The association of pituitary adenoma and adjacent cerebral aneurysm is not uncommon and acute hemorrhage into a pituitary adenoma is also a well recognized condition. However, the simultaneous occurrence of pituitary apoplexy with intracranial aneurysm is very rare. Such a case demonstrates the diagnostic difficulty in distinguishing between pituitary apoplexy and rupture of an aneurysm. We reported a patient with subarachnoid hemorrhage in whom a hemorrhage into the pituitary adenoma and a carotid-ophthalmic aneurysm was proven, and discussed the differential diagnosis and treatment. A 41-year-old man, who developed sudden severe headache with nausea and vomiting, was admitted to our hospital. Examination disclosed a mildly stuporous man with bilateral defects of upper lateral visual fields and lumbar puncture revealed subarachnoid hemorrhage. Plain radiographs of the skull showed an enlarged and eroded sella turcica. Carotid angiography revealed a left carotid-ophthalmic aneurysm. A plain CT scan demonstrated an acute suprasellar hematoma. A transsphenoidal operation was performed and postoperative course was uneventful.

Three young women who developed amenorrhea secondary to large, unsuspected pituitary tumors are described. They presented with acute onset of the triad of headache, nausea and vomiting, and visual abnormalities. One patient died; the other two retained some sequelae, and one had a significant hemiparesis. These devastating effects of pituitary apoplexy can be avoided in amenorrheic patients if the possibility of a pituitary tumor is considered early on. Lateral skull x-ray examinations are inexpensive an easily obtained and will usually demonstrate significant pituitary tumors. Early recognition and surgical removal of pituitary tumors carries low morbidity and mortality and will avoid an apoplectic crisis.

Phenylpropanolamine (PPA) is the major ingredient of many over-the-counter cold remedies and diet pills. Use or abuse of PPA may cause hemorrhagic stroke or cerebral vasculitis similar to the clinical and angiographic picture associated with amphetamine use or abuse. We report a 32-year-old Taiwanese women who developed sudden onset of severe headache, nausea and vomiting on the seventh day of oral ingestion of 75 mg PPA per day. Cerebral angiograms showed multiple areas of alternating focal constriction and dilatation ("beading" appearance) in the anterior and posterior cerebral arteries consistent with cerebral arteritis. This case should alert medical practitioners to the potential hazards of over-the-counter drugs like PPA.

During December 1993-September 1995, the Bureau of Food and Drug Safety, Texas Department of Health (TDH), received approximately 500 reports of adverse events in persons who consumed dietary supplement products containing ephedrine and associated alkaloids (pseudoephedrine, norephedrine, and N-methyl ephedrine). This total included reports by individuals and reports identified by the Bureau of Epidemiology, TDH, in a review of records from the six centers of the Texas Poison Center Network. Reported adverse events ranged in severity from tremor and headache to death in eight ephedrine users and included reports of stroke, myocardial infarction, chest pain, seizures, insomnia, nausea and vomiting, fatigue, and dizziness. Seven of the eight reported fatalities were attributed to myocardial infarction or cerebrovascular accident. This report describes three patients in which the recommended dosage for the dietary supplements reportedly was not exceeded, summarizes results from ongoing investigations, and underscores the potential health risks associated with the use of products containing ephedrine.

We present a case of persistent hiccups (singultus) after a lateral medullary cerebrovascular accident. The patient presented with a two-day history of nausea and vomiting. Clinically, the patient had a loss of pain and temperature on the left side of the face, a loss of pain and temperature on the right side of the trunk, a mild left hemiparesis, and a left-sided ataxia. Nystagmus, diplopia, and hiccups were also evident. A left lateral medullary syndrome in the vascular distribution of the posterior inferior cerebellar artery was diagnosed. Work-up included a magnetic resonance imaging angiogram, which revealed an occlusion v high-grade stenosis of the basilar artery. The patient reported that the most distressing symptom was the chronic hiccups (25/min), which interfered with nutrition, sleep, and activity. While in the acute care hospital, the patient was treated with prochlorperazine, promethazine, and chlorpromazine. Each of these medications was unsuccessful in stopping the hiccups. After a search of the European literature revealed that baclofen was recommended as the drug of choice for stopping persistent hiccups, the patient was given 5 mg of baclofen by mouth three times per day, and the hiccups abated within 48 hours. The baclofen was discontinued after one week of therapy, and the hiccups did not return. We recommend consideration of baclofen for the treatment of persistent hiccups after lateral medullary syndrome because of its desirable side effects and reported success rate compared with other drugs used to treat chronic hiccups.
