Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.

Nerve-root anomalies are very uncommon, and there symptoms and signs are nearly similar with those of disc herniation. So we can misdiagnois them for intervertebral disc herniation. The negative Lasegue' sign is the only distinct feature of the nerve root anomalies. The authors report a case of Nerve-Root Anomaly associated with disc herniation in lumbar 4-5 interspace, which was diagnosed preoperatively in myelogram and confirmed surgically.

Encapsulated and free pus in the substance of the brain tissue following an acute purulent infection is known as brain abscess, and which is uncommon. The brain abscess arise either as direct extention from infections within the cranial cavity or as hematogenous metastasis from infections elsewhere in the body. Since 1945, the antibiotics associated use of steroid and mannitol have been available for the treatment of brain abscess, and the result are very hopeful. The common method of surgical treatment are consist of excision and drainage and the problem of the best operative procedure has been disputed on the many neurosurgical literatures for many years. Recently we had treated 2 cases of severe otogenic brain abscesses with semicomatose patient by drainage, and good was the result compared with the other literatures. Result; 1. One case with semicoma recovered completely without any neurologic sequelae, and the other case recovered with visual disturbance. 2. The best operative procedure for the severe brain abscess considered a drainage.

PURPOSE: Tethered cord syndrome(TCS) is defined as low position of the conus medullaris by the abnormally fixed spinal cord with progressive neurologic deficit MATERIALS AND METHODS: To evaluate the findings of TCS at MRI and its diagnostic value, we performed a retrospective analysis of MRI of 30 patients with emphasis on clinical manifestation, level of conus medullaris, cause of tethering, and associated findings. RESULTS: Clinical presentation included back mass(26 cases), neurogenic bladder(5 cases), urinary incontinence(5 cases), progressive constipation(2 cases), skin dimpling(1 case), gait disturbance(1 case) and club foot (1 case). Neurologic deficit was developed in 11 cases(40% and mean age of these patients at the time of diagnosis was 8.6 years. The most common cause of tethering was lipoma(63%). The tips of conus medullaris were below the level of the second lumbar spine in all patients. The causes of tethering were lipomatous component(spinal lipoma and lipomyelomenigocele) in 67% myelomeningocele in 20%, presacral mass in 7%, thickened filum terminale in 3% and postoperative change in 3%. Associated anomalies included syringomyelia(20%) and hydrocephalus was associated in 3 out of 5 patients who underwent brain MRI. CONCLUSION: MRI clearly delineated the location of conus, tethering of the filum terminale with their causes and associated abnormalities. MRI examination is a very useful diagnostic tool for the early evaluation of TCS and the postoperative follow up.

BACKGROUND: The survival in patients with hepatocellular carcinoma (HCC) has recently been improved by the advancement in the early detection of HCC. Among the various treatment modalities, the surgical resection has been considered as the most effective for small HCC, and the clinical course of patients with small HCC who underwent curative resection is known to be dependent on the etiology of HCC. Since the differences in the etiology of HCC depend on the different geographical area, it is necessary to verify the clinical outcomes and their affecting factors in patients with small HCC after curative resection in Korea, one of the hepatitis- B-virus(HBU)-endemic areas. METHODS: A total of 89 patients with small HCC (

Pulmonary aspergillosis is classified as a saprophytic, allergic, and invasive disease. Chronic necrotizing pulmonary aspergillosis is categorized as an invasive pulmonary aspergillosis. Most invasive pulmonary aspergillosis have acute and toxic clinical features but chronic necrotizing pulmonary aspergillosis is characterized by a sub-acute infection, most commonly seen in patients with altered local defense system from preexisting pulmonary disease of in mild immunocompromised patients. Pulmonary artery aneurysm due to this infection is termed as a mycotic aneurysm, etiology of which are tuberculosis, syphilis, bacteria and fungus. We report a case chronic necrotizing pulmonary aspergillosis complicating pulmonary aneurysm is a 62 year-old man who was presented with cough, sputum, and fever. Chest radiographs showed a rapid, progressive cavitary lesion and pulmonary artery aneurysm. Angioinvastion of aspergillus was revealed by pathology after operative removal of left upper lobe containing the pulmonary artery aneurysm. He was treated with itraconazole.

Endoscopic variceal ligation (EVL) is effective for the management of bleeding esophageal varices, and its use is widespread now. EVL necessitates the use of overtubes. Two primary techniques have been used for overtube placement; one is with endoscope, and the other is with bougie dilator. Overtube placement with endoseope is not without risk. There are reportd of esophageal or pharyngeal laceration or perforation. Overtube placement with bougie dilator circumvents this risk, but it is rather cumbersome to use. The authors devised a safe and easy method for overtube placement, and applied it to a number of patients to test its safety and convenience. First, overtube-dilator assembly was prepared as follows. A Rigiflex achalasia dilator (balloon 30mm OD, 10cm length; Microvasive Co) was lubricated and inserted into the overtube. A tenth of the balloon tip was protruded out of the overtube, then the balloon was insufflated with air at 10-15 psi. Second, standard endoscopy was performed, followed by placement of guide wire in the stomach. Overtube-dilator assembly was lubricated and introduced over the wire as a rail. Once the overtube was properly positioned, the balloon was deflated, and the balloon and wire were removed as a whole, which completed overtube placement. For 65 patients with esophageal variceal bleeding, 82 procedures of EVL were performed using the new technique. Overtube-dilator assembly was easy to prepare and handle. This technique added little time to the procedure and minimizes patients discomfort. No patient suffered major complications such as bleeding, laceration or perforation. This novel method for overtube placement was safe and convenient for use in EVL. It can also be applied to other procedures using overtube such as endoscopic foreign body removal.

The activity and distribution of aspartate aminotransferase (EC 2.6.1.1) and alanine aminotransferase (EC 2.6.1.2) in adult Fasciola hepatica have been studied. Fasciola hepatica was fractionated by differential centrifugation into nuclear, mitochondrial and cytosolic fractions. The activity of GOT and GPT was measured by the method of Reitman and Frankel. Isozyme patterns of those enzyme were also examined by DEAE-cellulose column chromatography. The results obtained were as follows: The activity of aspartate and alanine aminotransferase was about 0.55 unit and 0.92 unit per 1 g of Fasciola hepatica, respectively. The activity of those enzymes was relatively low compared with those in mammalian tissues. The distribution of aspartate aminotransferase in the subcellular organelles showed that 71 percent of the activity was in cytosolic, 24 percent in mitochondrial and 5 percent was in nuclear fraction. About 22 percent of the total alanine aminotransferase activity was found in the mitochondrial fraction, about 66 percent in the cytosolic fraction. Aspartate aminotransferase from cytosolic fraction was separated into two types of isozymes, whereas alanine aminotransferase from cytosolic fraction gave only one active peak on DEAE-cellulose column chromatography.

BACKGROUND/AIMS: Combined esophageal variceal ligation and sclerotherapy has been hypothesized to be more effective for the control of bleeding esophageal varices than ligation alone. The present study was to compare the combined therapy with ligation alone in terms of variceal eradication, rebleeding, complication and survival rates in patients with bleeding esophageal varices. METHODS: Thirty-eight patients with bleeding esophageal varices were randomly assigned to receive ligation alone in 20 patients or the combined therapy in 18 patients. The clinical and endoscopic characteristics of patients in the ligation group were similar to those of patients in the combination group. In the combination group, 1-3 mL of ethanolamine was injected proximal to each ligated site. Treatments were repeated every 2- to 3-month until varices were eradicated. RESULTS: No significant differences were found between the ligation and combination groups in variceal eradication rates (70% vs. 72%), numbers of endoscopic sessions required to achieve eradication (3.5+/-0.33 vs. 3.3+/-0.31), rebleeding rates (30% vs. 28%) or 2-yr cumulative survival rates (95% vs. 75%). There were significantly more complications in the combination group (25% vs. 89%, p=0.001). CONCLUSION: Ligation alone is recommended rather than the combined ligation and sclerotherapy because of its lower complication rates.
