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 However, products containing PPA were withdrawn in sequence in the US, Japan, and Korea due to the increased risk of hemorrhagic stroke.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.

BACKGROUND: Neurological syndromes often complicate the management of infective endocarditis. METHODS: We reviewed the neurological complications in 100 patients with infective endocarditis in a tertiary care hospital. RESULTS: Neurological complications occurred in 25 patients (25%). Ischemic infarctions occurred in 15 patients, hemorrhagic infarctions in 5, intracerebral hemorrhages in 12, subarachnoid hemorrhages in 4, and subdural hemorrhages in 2. Brain abscess was detected in 4 and seizures in 2 patients. Staphylococcus aureus endocarditis (p=0.01) and mitral valvular heart disease (p=0.015) correlated statistically with the development of neurological complications. The mortality rate was significantly higher in patients with neurological complications than those without neurological complications (p=0.00). Age, sex, and type of valve (native versus prosthetic) were not related to the complication rate. CONCLUSIONS: We concluded that (1) hemorrhagic complications occurred at a higher rate in this study than previous reports; (2) S.aureus infection and mitral valvular disease predicted the occurrence of neurological complications; and (3) neurological complications were related to mortality rates.

We performed original and modified technique of Mays' glanuloplasty in 6 and 12 cases respectively. The results were as follows: 1. 6 cases of mild from of hypospadias (2 cases of coronal, 4 cases of dist. penile) and 12 cases of severe form of hypospadias (5 cases of prox. penile, 6 cases of penoscrotal, 1 case of perineal) on pre-chordectomy but all cases became severe from of hypospadias (2 cases of prox. penile, 15 cases of penoscrotal, 1 case of perineal) on post-chordectomy. 2. The postoperative complications were 3 cases (50.0%) (1 case of meatal stenosis, 2 cases of meatal necrosis) in original technique of Mays' glanuloplasty and 2 cases of meatal stenosis (16.7%) in modified technique of Mays' glanuloplasty.

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.

Microform cleft lip is a mild form of incomplete cleft lip, also known as a minimal occult, abortive, forme fruste cleft lip. However, it has no definition and few methods have been reported for its correction. A microform cleft lip is characterized as the incomplete union of the superficial portion of the orbicularis oris muscle. It is more prominent during facial expression than in a resting state. We confined microform cleft lip in our study to the absence of philtral skin change and a contracted position on the top of cupid's bow. During the past 5 years, 17 patients of microform cleft lip were operated on. We corrected the defect of the upper vermilion border and nostril sill with minimal incision, and repaired the underlying lip musculature in superficial discontinuity. Reduction of the widened alar base was performed. Deformed alar cartilage was dissected via rim incision, and suspended in a medial and upper direction with pull-out sutures. The most important thing is precise repair of the superficial portion of the separated orbicularis oris muscle via minimal incision, and it is best to operate after 1-year of age for accurate repair. The results were satisfactory and the parents were also satisfied. The advantages of this procedure are as follows: 1. Less visible, minimal scar on upper lip 2. Simultaneous correction of vermillion notching, deformed cupid's bow and nasal deformity. 3. Eversion of philtral ridge due to tenting effect of horizontal mattress suture 4. Philtral elongation effect by reduction of alar base and Z-plasty of cupid's bow.

The mechanisms involved in brain neuronal damage in ischemia are related to the elevation of cytosolic calcium concentration and calcium antagonist is considered as a promising drug that may alleviate ischemic neuronal damage. Using transient global ischemia model of Mongolian gerbil, we studied the effect of nimodipine, a cerebroselective calcium antagonist, on ischemic brain edema. We treated each gerbil intraperitoneally with nimodipine (lmg/kg) or the same amount of saline 30 minutes prior to ischemia, and transient global ischemia was induced by means of clipping both common carotid arteries either for 10 minutes or for 45 minutes. Three hours after reperfusion, the animals were decapitated and the water content of the bain was determined by oven dry method. With 10 minute ischemia the brain water content in nimodipine pretreatment group (78.6 +/- 0.2%) was lower than that in saline pretreatment group (79.1 +/- 0.4%) significantly (p<0.05). But with 45 minute ischemia nimodipine pretreatment did not reduce the postischemic increase of water content compared with saline pretreatment (79.8 +/- 0.4% and 79 6 +/- 0.4%, respectively; not significant). Our results suggest that nimodipine pretreatment may suppress the development of ischemic brain edema and its effect depends largely on the extent of brain ischemia.

Transient ischemic attack (TIA) often precede cerebral infarcts as a warning symptom. But the studies revealing the frequency and the correlation between preceding TIAs and following infarcts are rare. According to the western data, about one-quarter of the patients with cerebral infarct have been supposed to have the previous history of TIAs. We prospectively studied the exact frequency, clinical presentation, and presumed causes of TIAs preceding cerebral infarct. Ninety five patients diagnosed as acute cerebral infarction were interviewed whether they had had previous episodes of TIA. 4 check-list using ordinary language was used, and NINDS diagnostic criteria was applied on the consensus between several neurologists. Seventeen patients (18%) had history of preceding TIAs. Carotid territory was affected in 11 patients (65%), while vertebrobasilar in 4(24%) and undetermined in 2. Duration was less than an hour in 10 patients(59%), and attacks were multiple in about half. Time interval between the last attack and infarction was less than one week in 10 cases(59%). Incidence of recent TIA ((1 month) was 22% in large artery disease(LAD), 11% In cardioembolism(CE), 9% in small-artery disease(SAD), and 7% in mixed etiology. Conclusion, TIAs preceding cerebral infarcts are not rare, but seems to be less common in Koreans than in Caucasians. As expected, atherothrombosis of large artery is supposed to be the leading cause of TIAs.
