We report two patients with solitary thalamic abscesses, occurring among 91 consecutive patients (2.2%) with computed tomography (CT)-diagnosed and surgically-verified brain abscess experienced in our college during 1975 to 1991. A 9-year-old girl with congenital heart disease experienced frequent vomiting followed by left hemiparesis and deterioration of consciousness. CT demonstrated a right thalamic ring-enhanced lesion. Purulent material was aspirated via a burr hole. She died of heart failure on the 5th postoperative day. Autopsy disclosed diffuse brain swelling and an encapsulated abscess in the right thalamus, which had ruptured into the third ventricle. A 30-year-old female experienced headache, nausea, and vomiting, which progressed to somnolence and right hemiparesis. CT demonstrated a left thalamic ring-enhanced lesion. Purulent material was aspirated by stereotactic procedures. All symptoms had resolved by the end of the 2nd postoperative week.

Clinical features of cerebellar infarction in the territory of the superior cerebellar artery (SCA) were investigated in six male patients, ranging in age from 50 to 69 years. In all patients, there were MR images of infarction located in the area supplied by the SCA. The lesion was on the left-side in 2, right-side in 3 and bilateral (recurrent) in 1 patient. The onset of disease occurred with nausea, vomiting and floating sensation, with no overt brain stem signs other than symptoms of unilateral cerebellar ataxia and dysarthria. Five of the 6 patients had heart disease and cerebral angiography without definite evidence of SCA occlusion, strongly suggesting occlusion of the artery at its periphery due to cardiogenic embolism. A comparison of these 6 patients with those reported previously in Japan suggests that patients with SCA occlusion may be divided into two distinct subgroups: one manifesting diffuse brain stem signs in addition to cerebellar signs, and the other showing cerebellar signs as the only neurologic manifestation. In the former group, comprising the vast majority of patients, SCA occlusion occurred at the origin of the vessel due to a thrombus under a state of hypertension, diabetes mellitus or malignancy, producing signs of brain stem involvement, such as dissociating sensory disturbance and Horner's sign. While in the latter group, which included these 6 patients, paucity of brain stem signs, absence of definite cerebral angiographic evidence of SCA occlusion, and the presence of heart disease were distinguishing clinical features. Cardiogenic cerebral embolism was probably the underlying pathology in many of the cases and the functional prognosis was favorable.

Long-term prostaglandin (PG) therapy has recently been associated with gastric mucosal hyperplasia. We reviewed the clinical and radiologic (especially sonographic) records of eight patients with complex congenital heart disease who were on PG therapy. Feeding problems, vomiting, and abdominal distension were present in six patients. Barium meal revealed antral narrowing in three patients, suggestive of hypertrophic pyloric stenosis in two. Sonography showed a variable degree of increased gastric mucosal lobulation often accompanied by a marked polypoid or lobular appearance. Cortical hyperostosis related to PG therapy was seen in three patients. PG-associated gastric mucosal hyperplasia can cause feeding problems and pronounced gastric lobulation.

5-Fluorouracil (5-FU) is a chemotherapeutic agent which has been used to treat many solid tumors including cancers of the breast, ovary, cervix, bladder, prostate gland and gastrointestinal tract. Side effects related to the drug include bone marrow suppression, stomatitis, nausea, vomiting and diarrhea. However another less frequent but lethal event cardiotoxicity--appears to have been ignored by physicians. Recently, two cases of cardiac toxicity induced by 5-FU have been encountered here. One patient developed supraventricular tachycardia and the other illustrated silent myocardial infarction with congestive heart failure. Since these side effects may result in death when 5-FU is prescribed to those patients who have had previous heart disease or are concomitantly receiving inevitable radiotherapy over the cardiac region, it should be recommended with extreme caution.

This paper analyzes the available literature on intracranial arteriovenous malformations (AVM) in Taiwan. The incidence and symptoms of the disease are studied with a view to assisting practitioners in its recognition. The incidence of intracranial AVM in patients who have suffered hemorrhagic stroke in Taiwan is 2.5% to 4.8%, with the male to female ratio being 1.5:1. The peak age at which bleeding from intracranial AVM occurred ranged from 10 to 40 years; bleeding showed no seasonal variation. Sudden headaches, vomiting, and disturbance of consciousness were the commonest presenting symptoms of AVM, similar to the rupture of intracranial aneurysms. However, the possibility of focal neurological deficit among patients with intracranial AVM was higher than in patients with intracranial aneurysms. Risk factors, such as hypertension, diabetes mellitus, heart disease, smoking and alcohol intake showed no close relationship to bleeding in intracranial AVM. Pregnancy is not a risk factor in female patients with intracranial AVM with no history of hemorrhage. Small intracranial AVM are more likely to bleed. Since 1961 the majority of Taiwan's intracranial AVM patients have been treated surgically, while before that date general medicine was the treatment of choice. In recent years, several developments such as operation microscope, microsurgical instruments and microsurgical techniques have enhanced the efficacy of surgical intervention in the treatment of AVM. When the mortality and morbidity rates resulting from the two forms of treatment are compared, surgical treatment shows a better prognosis for the treatment of intracranial AVM.

Prostaglandin infusion is used to maintain patency of the ductus arteriosus in infants with cyanotic congenital heart disease. Recently, gastric outlet obstruction as a result of prostaglandin infusion has been described. In our case, an upper gastrointestinal contrast study seemed to depict the typical appearance of pyloric stenosis in an infant who had received an infusion of prostaglandin for a prolonged period. Serial ultrasonograms, however, disclosed progressive elongation of the antropyloric channel without wall thickening. This report is the second to illustrate prostaglandin-induced gastric outlet obstruction in a vomiting infant with a gastrointestinal series diagnosis of pyloric stenosis.

The US Food and Drug Administration has not yet approved combined estrogen/progesterone compounds for postcoital contraception (PCC), yet administering them has been an accepted practice for at least 10 years. The health service at the University of Rochester in New York has a formal protocol to dispense PCC to female students who have had unprotected intercourse and wish to prevent pregnancy. The women must have experienced unprotected intercourse within 72 hours prior to presenting at the clinic. The clinicians screen the women for absolute contraindications to oral contraceptives (OCs), which include blood clotting disorders, stroke, heart disease, cancer of the breast or reproductive tract, and liver tumors. They also determine whether conception has occurred. If indeed it has occurred, and the patient has given written consent, the clinicians administers 2 times the dosage of 1 OC to the patient and a repeat dose 12 hours later. She is seen at the clinic 3 weeks later. Clinic workers review their protocol every 6-12 months as part of the quality assurance program. Providers who do not approve of PCC are asked not to see students requesting PCC. Between March, 1985, and February, 1991, the service's staff administered PCC 209 times. 18.7% of PCC patients took PCC more than once. Date rape was responsible for 3 episodes of unprotected intercourse. Pregnancy occurred in 4 of the 209 PCC episodes (1.9%). 3 of these pregnancies were not midcycle exposures. All 4 cases had received PCC within 24 hours of unprotected intercourse. They all underwent an abortion. The expected pregnancy rate for unprotected intercourse without PCC would be 11-14%. Side effects were nausea (19%), vomiting (13%), and other symptoms (8%), including headache, cramps, menstrual irregularities, or abdominal pain. Another possible PCC is mifepristone, which was 100% effective in a study in Scotland. It probably will not be available soon in the US because of the controversy surrounding its use as an abortifacient.

The systemic toxicity of doxorubicin, 30 mg/m2 body surface area (BSA) every 21 days to a cumulative dose of 300 mg/m2, was evaluated in six cats. Appetite, body weight, and the presence of vomiting and/or diarrhea were monitored throughout the study. Renal function was monitored by measuring serum blood urea nitrogen (BUN) and creatinine concentrations, urine specific gravity, and creatinine clearance before each treatment. Electrocardiograms and echocardiograms were also done before each treatment. The cats were killed 3 weeks after the last treatment, and complete necropsies were performed. Partial or complete anorexia occurred in all cats with significant weight loss occurring after a cumulative doxorubicin dose of 150 mg/m2 BSA. Mild vomiting and diarrhea that required no treatment also occurred sporadically in all cats. Echocardiographic changes consistent with doxorubicin-induced cardiomyopathy occurred in four cats after cumulative doses of 170 to 240 mg/m2 BSA. Clinical heart disease and electrocardiographic changes were not observed. Subsequent histological examination revealed myocyte vacuolization and myocytolysis in all six hearts. Renal dysfunction, characterized by increasing azotemia with progressively more dilute urine, was detected in two cats. Mean creatinine clearance values also decreased significantly throughout the study. At necropsy, all cats had histological evidence of renal disease.

The purpose of this prospective study was to determine the safety and efficacy of chloral hydrate sedation in children with known or suspected congenital heart disease. The study population included 405 children with a median age of 13 months (3 weeks to 14 years). Cyanotic heart disease was present in 64 of the children. The median dosage of chloral hydrate given was 77 mg/kg, with a range of 25 to 125 mg/kg. Sedation was achieved in 397 (98%) of the children. The complete study time averaged 2.2 hours (range, 1.6 to 5.2 hours). The time to achieve sedation was 30 minutes or less in 82%, more than 30 but less than 60 minutes in 12%, and more than 60 minutes in 4%; 2% failed to achieve sedation. Children aged 3 years or younger were more likely to be successfully sedated with chloral hydrate (p = 0.003). The type of heart disease did not affect the success of sedation. No child had a clinically significant change in heart rate or blood pressure during sedation; however, oxygen saturation decreased in 24 (6%) of 397 children successfully sedated. Decreases in oxygen saturation occurred more commonly in children with trisomy 21 (7/13) than in children without genetic syndromes (17/384). Vomiting occurred in 23 (6%) of the 405 study subjects, usually immediately after drug administration. Chloral hydrate is a safe and effective agent for sedation of children with known or suspected congenital heart disease who are undergoing echocardiography in the outpatient cardiology clinic.

Sixty-seven patients with brain abscess were managed over 19 years (1975-1993). Our series had a 2.5 to 1 male predominance; the age distribution was from 3 days to 81 years. The underlying conditions of hematogenic brain abscesses (n = 33; 49%) included lung infections (n = 16), heart disease (n = 4), sepsis (n = 10), and other foci (n = 3). Otolaryngologic infections led to the abscess in 10 cases; there were 9 traumatic abscesses. The causes remained unknown in 15 cases. There were 47 solitary abscesses (70%) and 20 multiple abscesses. The most frequent presenting signs and symptoms were neurologic deficits (n = 17), disturbances of consciousness (n = 14), seizures (n = 6), and headaches, meningism and vomiting (n = 13). Causative organisms were isolated in 39 cases (58%) and included staphylococci (n = 6), streptococci (n = 6), enterobacteriae (n = 2), and anaerobic pathogens (n = 9). The most reliable laboratory sign of inflammation was an elevated ESR (52/59 patients). With the advent of computed tomography, burr hole aspiration of the abscess with or without drainage was possible in 30 cases; the mortality in this subgroup was 9%. All 4 patients with surgical excision in the pre CT-era died. The mortality of patients treated with antibiotics only was 62% (18/29). Overall mortality was 37% (25/67), including 5 cases with post mortem-diagnosis of brain abscess. Good recovery was achieved in 29/42 survivors. Predictors of a poor outcome were the patient's age, the level of consciousness, multiple abscesses, polybacterial cultures, and a hematogenic etiology, but not the size of the abscess.
