PURPOSE: To determine the usefulness of microbubble contrast enhanced power Doppler ultrasonography (PDUS)for the detection of residual tumor in hepatocellular carcinomas (HCCs) treated by transcatheter arterialchemoembolization (TACE). MATERIALS AND METHODS: Fourteen nodular HCCs (size range: 1 - 7.3 cm, mean: 3.5) intwelve patients treated by TACE, and on the basis of follow-up liver CT, thought to have a residual tumor, wereincluded in this study. Between July 1997 and April 1998, PDUS examinations were performed with a 2-4 MHz convextransducer before and after intravenous injection of a microbubble contrast agent (Levovist(, Schering AG, Berlin,Germany). Real-time power Doppler ultrasonographic images were recorded on videotape and representative imageswere color-printed. Tumor vascularity was analyzed on real-time images with regard to its presence or absence, andchanges, and two observers reached a consensus. The results were compared with those of other diagnostic tests(three-phase helical CT, conventional angiography, percutaneous biopsy, and/or surgical pathology). RESULTS: Contrast-enhanced PDUS revealed intratumoral vascularity in ten of 14 tumors, none of which showed vascularity onunenhanced PDUS. In the remaining four tumors, both unenhanced and enhanced PDUS showed intratumoral tumorvascularity, which in all cases was more pronounced on enhanced than on unenhanced PDUS. Other diagnostic testsrevealed residual tumors in eleven lesions. CONCLUSION: Microbubble contrast-enhanced PDUS was more sensitivethan non-enhanced PDUS in depicting vascularity within a residual tumor and could be a useful method for thedetection of residual tumor in HCCs treated by TACE.

Cardiovascular respons follwing ethanol ingeation was conapared in two groups of male college studenta; 20 who ahowed visble facial flushing and 25 whe showed on flushing. Ethanol was administered as 25% Korean liquor (Kumbokju) a dose of 2ml per kg body weight, the heart rate, blood pressure and respiratory rate were measured. The reaults areas follows. The heart rate after ethanol ingestion increased significantly in both flushing and non-flushing groups. However, the degree of the heart rate increased in the flushing group was aignificantly higher than that in the non-flushing group. The blood pressure was decreased significantly from 40minutes after ethanol ingestion in both groups. Howyer, the flushing group showed higher systolic pressure, and lower diastalic pressure and mean arterial pressure than the non-flushing group. The reapiratory rate following ethanol administration was increased in the flushing group but decreased in the non-flishing group when compared with the resting respiratory rate. The results clearly indicate that a signifcant difference in cardiovascular resoponrses to ethanol exists the flushing and non-flushing groups. The flushing group shows a greater tachycardia and greater fall in. mean arterial pressure followig ethanol ingestion than the non-flushing group.

The routine screening of patients for hypercalcemia has increased the incidence of hyperpa-rathyroidism, But, Primary hyperparathyroidism is relatively rare disease in korea. Especially, primary hyperparathyroidism caused by parathyroid chief cell hyperplasia has not been reported. The numbers of patients with bone disease, renal stones, other severe complication has declined, but the numbers of patients with psychiatric and neuromuscular disturbance or with asymptomatic disease has increased. We experienced a case with severe bone diseases due to primary hyperparathyroidism caused by parathyroid chief cell hyprepiasia which was confirmed through the mearsurement of serum calcium and parathyroid hormone, neck CT scanning and surgical exploration and which was managed by total parathyroidectomy with autotransplantation.

We present two very interesting cases of acute graft-versus-host disease (GVHD), whose skin rashes initially appeared on the localized area of total nodal irradiation (TNI) performed previously to prevent graft rejection and/or GVHD. The histopathologic findings showed some dyskeratotic cells in the epidermis and perivascular mononuclear cell infiltration in the upper dermis. The immunohistochemical studies revealed that HLA-DR was diffusely strongly positive in a number of keratinocytes, whereas both CD4 and CD8 were focally weakly positive in the perivascular lymphocytes in the upper dermis. Later on, liver dysfunction and diarrhea developed and skin rashes began to spread over the other parts of the body in those two patients.

PURPOSE: To assess the effectiveness of ethanol embolization for the treatment of arteriovenous malformation (AVM), and the complications, if any, arising. MATERIALS AND METHODS: Thirty-three patients with AVMs underwent 145 staged sessions of ethanol embolization. AVMs were located in an upper extremity (n=14), a lower extremity (n=10), the pelvis (n=7), the thorax (n=1), or the abdomen (n=1). Eighty-five transcatheter embolizations and 60 direct percutaneous puncture embolizations were performed, and seven patients underwent additional coil embolization of the dilated outflow vein. The therapeutic effectiveness of embolization was evaluated in terms of the extent to which an AVM was obliterated between baseline and the final angiogram. Complications were classified as minor or major. RESULTS: In 13 patients (39%), AVMs were totally obliterated. In eitht patients (24%), more than 75% were obliterated; in three (9%), the proportion was 50-75%; and in four (12%), less than 50%. Five patients (15%), were not treated. The reasons for failure were the difficulty of approaching the nidus due to previous surgical ligation or coil embolization of the feeding artery, the subcutaneous location of an AVM, post-procedural infection, and massive bleeding during the follow-up period. Twenty-one minor complications such as focal skin necrosis or transient nerve palsy developed during 145 sessions of (an incidence of 14%), but these were relieved by conservative treatment. The five major complications arising (3%) were cerebral infarction, urinary tract infection, acute renal failure due to rhabdomyolysis, permanent median nerve palsy, and infection. CONCLUSION: Ethanol embolization by direct percutaneous puncture or using a transcatheter technique is an effective approach to the treatment of an AVM. However, to overcome the considerable number of complications arising, further investigation is required.

Acute eosinophilic pneumonia is reported as a specific disease entity. But, it is different from chronic eosinophilic pneumonia in its onset, clinical course and recurrence. Badesh et al reported the following diagnostic criteria os acute eosinophilic pneumonia a less than one-month history of symptoms prior to diagnosis, no evidence of asthma, the absence of other organic disease, no obvious etiology and an evidence of recurrent disease. We experienced a case of acute eosinophilic pneumonia in 37 old male. Pathologically eosinophilic pneumonia is confirmed and other features meet Badesh's criteria.

Disseminated mucormycosis is a rare fungal infectious disease with a high mortality rate and is infrequently diagnosed ante mortem. It is most frequently seen in immunocompromised hosts such as diabetes mellitus, hematologic malignancies, or in the long-term use of steroids or chemotherapeutic agents. Tissue invasion by the hyphae of mucormycosis must be seen microscopically to establish the diagnosis. Treatment consists of correction of the predisposing condition, surgical debridement, and amphotericin-B therapy. A 35-year-old man was admitted through the emergency room due to fever and the right flank pain. He had received an allogenic bone marrow transplantation eight months ago and had been medicated with prednisolone and cyclosporine since the procedure. He was diagnosed with disseminated mucormycosis that involved the spleen, right kidney, and right lung. He is being successfully treated with amphotericin B, flucytosine, and liposomal amphotericin B.

Mitochondrial encephalomyopathy with lactic acid and stroke-like episodes (MELAS) is a multisystem mitochondrial disorder that typically presents in childhood. We report a case of MELAS syndrome diagnosed in a 45-year-old man presented with chronic kidney disease before a stroke-like episode. Genetic testing revealed a m.3243A>G point mutation in the mtDNA. The original diagnostic criteria for MELAS required the onset of stroke-like episodes prior to 40 years of age but this case demonstrates that disease onset may delay in certain individuals.
