A male child of 9 months with bilateral Wilms tumor was admitted to our hospital. His chief complaint was abdominal mass. Clinical examination and IVP, USG and CT-scan disclosed bilateral Wilms tumor. Right nephrectomy and left partial nephrectomy were performed. Anuria was experienced to 24 hours and so exploratory-laparotomy was done. Renal autotranplantation was performed because of the thrombosis of renal artery. But six days after operation he died.

OBJECTIVES: Phenylpropanolamine (PPA) had been used widely as cold remedies or appetite suppressants. However, products containing PPA were withdrawn in sequence in the US, Japan, and Korea due to the increased risk of hemorrhagic stroke. The purpose of this paper was to review safety issues related with the PPA use and hemorrhagic stroke in view of pharmacoepidemiology and pharmacovigilance. METHODS AND MATERIALS: Researches conducted for evaluating the association between the PPA use and hemorrhagic stroke in other countries were reviewed, which involved case reports, case series, case-control studies, and cohort studies. RESULTS: In terms of pharmacologic and clinical features, PPA may increase the risk of hemorrhagic stroke through increased blood pressure, heart rate, or vasculitis. The association between the PPA use and hemorrhagic stroke among young women was suggested by case reports from spontaneous adverse events reporting systems or medical journals. The cohort study, using the large prescription database in the US and published in 1984, failed to reveal the association in the population aged below 65. The case-control study conducted as the Yale Hemorrhagic Stroke Project, published in 2000, was the first study to find the association between the PPA as appetite suppressants and hemorrhagic stroke among women ages 18-49 years by well-designed analytic epidemiological research. It led to withdrawal of all products containing PPA in the US and many other countries since 2000. However, the association between PPA and cerebral hemorrhage could not be confirmed by the case-control study conducted in Mexico due to inappropriate recruitment of control group. CONCLUSIONS: During several years case reports have suggested that hemorrhagic stroke could be induced by PPA, and the Yale Hemorrhagic Stroke Project revealed the association by case-control study and provided a useful model for pharmacovigilance. Nevertheless, their finding could not be applied to other population such as elderly women and male population. And they could not provide any evidence on the association between PPA and stroke when PPA was used as cold remedy taken daily dose below 100mg.

Homocystinuria is an inborn error of methionine metabolism and has several causes. Among the causes, cystathionine-b-synthase deficiency is the most common. The major clinical manifestations are ectopia lectis skeletal deformities, mental retardation and occlusive vascular disease A 16 year old girl was admitted with generalized seizure. She had a history of bilateral lens dislocation and thoracic scoliosis. Her brain MRI and MRA showed mass-like lesions at both frontal area and diffuses, stenosis of the right internal carotid artery She underwent a stereotaxic brain biopsy and cerebral angiography. Two days, after angiography, she was suddenly aggravated to show stuporous mentality and quadriplegia. FoIlow-up brain MRI showed newly developed acute ischemic lesions at both parietal area MR venography confirmed superior sagittal sinus thrombosis. Methionine and homocystine were markedly elevated in plasma and 24 hour urine. She recovered with anticoagulation and vitamin supplementation(folate and pyridoxine). Homocystinuria should be suspected in stroke patients of young age, especially if thy have nontraumatic lens dislocation or marfanoid features. We report a patient with homocystinuria complicated by cerebral venous sinus thrombosis which was aggrevated after cerebral angiography.

Journal of the Korean Neurological Association 1999;17(6):920-923
Duret hemorrhage is characterized by an upper brainstem hemorrhage due to increased intracranial pressure by mass effect such as subdural hematoma or a brain tumor. The anteroposterior elongation and downward displacement of the upper brainstem by transtentorial herniation results in the compression and tearing of the paramedian perforating vessels that feed the upper brainstem tegmentum. The consequent hemorrhage that involves the upper brainstem renders recovery to be almost impossible. Following a tricuspid valve replacement surgery, a 56-year-old woman developed a left fronto-temporo-parietal nontraumatic subdural hematoma resulting in transtentorial herniation of the left mesial temporal lobe. A successful surgical evacuation of the hematoma was done with clinical improvement. Two days later, she was referred to neurology with an aggravated right side weakness, dysarthria, and a newly developed extraocular movement disturbance. A brain CT and MRI showed a pontine hemorrhage. We report a case of pontine hemorrhage, a Duret hemorrhage, after the surgical evacuation of nontraumatic subdural hematoma.

PURPOSE: To report three cases of rituximab treatment in refractory orbital inflammatory disease. CASE SUMMARY: Rituximab treatment was performed in three patients (thyroid-associated ophthalmopathy, orbital myositis, and idiopathic sclerosing inflammation) unresponsive to corticosteroid and radiotherapy. One cycle consisted of intravenous infusion of 1000 mg of rituximab, twice at a two-week interval. The patient with thyroid-associated ophthalmopathy exhibited clinical improvement in visual acuity, color vision, visual evoked potential, and visual field after one cycle of rituximab treatment. The patient with orbital myositis improved showed diplopia with a decrease in the size of the extraocular muscle after two cycles of treatment. The patient with idiopathic sclerosing inflammation showed improvements in visual acuity and visual field defect after one cycle of therapy. There were no severe infections or hematologic adverse effects including neutropenia, or decreased immunoglobulin during the follow-up period. CONCLUSIONS: Treatment with rituximab appears to offer another therapeutic option in patients unresponsive to corticosteroid or radiotherapy.

BACKGROUND: Epidurally administered clonidine represents an approach to control the pain after cesarean section that produces analgesia by an alpha 2-adrenergic mechanism and may provide postoperative analgesia without nausea, pruritus, and respiratory depression associated with systemic or intraspinal opioid administration. This study was undertaken to evaluate the analgesic effect according to the dose of appropriate bolus and the combination of epidural morphine and clonidine after cesarean section. METHOD: Forty five women, ASA physical status 1 or 2, scheduled for elective cesarean section were randomly assigned to receive epidural administration for postoperative pain control. Group A (n=15) received 1 mg morphine and 75 g clonidine bolus followed by 4 mg morphine and 150 g clonidine. Group B received 2 mg morphine and 75 g clonidine bolus followed by 4 mg morphine and 300 g clonidine. Group C received 3 mg morphine and 75 g clonidine bolus followed by 4 mg morphine and 450 g clonidine. Each combination of drug was injected at Bromage scale 1 after surgery. RESULTS: All groups showed relatively stable hemodynamic status. Analgesic effect was significantly better in Group B and C than Group A (p<0.05). Sedative effect was not a problem in all groups. The incidence of side effects in Group C was more than Group B, which than Group A, but almost cases did not require treatment. CONCLUSION: 2 mg morphine and 75 g clonidine bolus followed by 4 mg morphine and 300 g clonidine with excellent analgesic effect and less side effects is considered as adequate dose in postoperative pain control after cesarean section with epidural anesthesia.

10.Medical Treatment of Ischemic Stroke.
Journal of the Korean Medical Association 2004;47(7):631-635
Stroke ranks as one of the leading causes of death and the most common cause of permanent disability in adults in Korea. Timely recognition and treatment is imperative to reduce stroke-related morbidity and mortality. Patients with acute ischemic stroke should be evaluated for intravenous thrombolysis with recombinant tissue-plasminogen activator (rt-PA); antiplatelet drugs can be administered to those who do not qualify for rt-PA therapy. Adequate hydration and correction of possible hypoxia are necessary, and hyperglycemia and fever should be treated aggressively. Blood pressure management should be individualized on the basis of stroke pathophysiology. It is important to prevent and manage complications of acute stroke, such as pneumonia, urinary tract infection, bed sore, deep vein thrombosis, and joint contracture. Meticulous evaluation of etiology of ischemic stroke can determine the most appropriate acute management and would guide the secondary prevention of stroke.
