It is a known fact that the increase of intraocular pressure results from the action of succinylcholine, endotracheal stimulation to carina, bucking and coughing etc during the induction arid recovery periods. Efforts have been made by several inveatigators to prevent intraocular hypertension by giving trimetaphan, inderal or curare. However, their effects were not remarkable. In this study, lidocaine Img/tg was administered intravenously to selectee patients 2-3 minutes hefore induction ; followed by regular induction with pentothal, succinylcholine and incubation. Intraocular pressures were measured at the pre-induction and post-intutation time, and every 30 minutes until the early recovery period, thereafter. The result of this study showed that the post-intubational increase of intraocular pressure was prevented in 86.7% of the lidocaine pretreated cases. The increase of post-extuba-tional intraocular pressure was also reduced significantly in the lidocaine pretreated group-as well. We came to the conclusion that lidocaine pretreatment technic can be used effectively to prevent intraocular hyperteilsion caused by induction and extubation in clinical practice.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

BACKGROUND: Psoriatic lesions have reduced water-holding capacity and show increased transepidermal water loss (TEWL). The effect of D-PUVA therapy, which combines topical calcipotriol and PUVA therapy, on epidermal barrier function has not yet been evaluated. OBJECTIVE: The purpose of this study was to verify the change of TEWL in lesional and normal skin according to D-PUVA therapy in psoriasis patients. METHODS: TEWL was measured consecutively by TEWAMETER TM210®, in 13 psoriasis patients who received D-PUVA therapy. Clinical grading was done according to psoriasis severity index (PSI). RESULTS: TEWL of psoriatic lesion decreased as D-PUVA continued. TEWL of normal-looking skin gradually increased, although the increase was trivial. Clinical grading of scale and in-filtration followed the pattern of PSI in the decrease of TEWL, while that of erythema did not. CONCLUSION: In psoriatic plaques, TEWL was decreased according to the improvement. In normal-looking skin, D-PUVA therapy caused only a little effect on TEWL.

Primary gallbladder cancer is a highly malignant tumor and is characterized by early metastasis and rapid progression of disease. Since the majority of patients have unresectable disease, laparotomy, instead of providing relief of symptoms, often adds to the morbidity and needs to be avoided in patients with advanced disease. Clinical features, peritoneoscopic findings, and comparison of peritoneoscopy with radiologic studies were reviewed in 29 patients, who underwent peritoneoscopy, with primary gallbladder cancer at Severaace Hospital, College of Medicine, Yonsei University between Aug. 1982 and Mar. 1994.

Bizarre parosteal osteochondromatous proliferation (BPOP) is an rare benign tumor which involve mostly tubular bones of feet and hand. BPOP has clinical, radiographic, and histologic similarities with osteochondroma.Radiologically, BPOP has not central continuity with underlying osseous medulla. Histologically, the lesion has marked proliferative activity, and enlarged, bizzare, and binucleated chondrocytes.Despite the high risk of recurrence, treatment of choice is surgical resection. This report presents two cases of BPOP of the big toe with reviews of clinical, radiographic, and histological characteristics.

PURPOSE: Neoplastic development is a multistep process that involves the accumulation of genetic alterations in proto- oncogenes, DNA repair genes, and tumor suppressor genes. Molecular studies in carcinoma have shown the high frequency of loss of heterozygosity (LOH) in some specific chromosome regions, but LOH on the HCC chromosome has not been thoroughly investigated in Korea. LOH is considered to be phenotypes of genomic instability. We investigated the genetic instability and microsatellite alterations of chromosome 5, 8, 13 and 17 in hepatocellular carcinoma (HCC). METHODS: Microsatellite alteration analysis was performed using polymerase chain reaction with 12 polymorphic microsatellite markers (BAT26, D5S123, D5S346, D8S254, D8S261, D8S262, D13S153, D13S159, D13S171, D17S250, D17S796, TP53) in 37 surgically resected HCCs and their respective non-tumorous counterparts. Pairs of tumorous part and normal tissue in the same patient were compared and then the size of microsatellite markers was measured. RESULTS: MSI was detected in 3 samples and LOH was detected in 51 samples of 37 cases. Fractional allelic loss (FAL) was above 0.2 in 10 cases and was correlate with high grade of HCC. we could detect only 1 case of LOH in D8S254 marker, which was advanced cancer. Markers D5S123 and D5S346 showed 2 and 3 cases of LOH, respectively. Markers D8S262, D17S250 and D17S796 had LOH and were significantly correlated with tumor grade. CONCLUSION: According to the results, our data revealed that specific LOH, rather than MSI, may be involved in hepatocarcinogenesis. LOH may be a useful tool for following HCC patients because the high frequency of LOH correlates with poor prognosis of HCC.
