PURPOSE: To evaluate the relative value of arterial, portal venous and delayed phase images of spiral CT in the detection of metastatic tumor of the liver. MATERIALS AND METHODS: Forty-three metastatic tumors in twelve patients were underwent tri-phasic spiral CT examination with injection of 120 ml ionic contrast material (36 g of iodine) at the rate of 3 ml/sec. Arterial, portal venous and delayed phase CT images were obtained 35, 65, and 360 seconds after the start of contrast injection, respectively. RESULTS: Arterial phase images detected 35(81%), portal venous phase images 43(100%), and delayed phase images 34(79%) lesions, respectively(p<0.05). All masses larger than 2cm(n=23) were detected in all three phases, whereas 60%, 100%, 55%of the masses smaller than 2cm(n=20) were detected in arterial, portal venous and delayed phase CT, respectively. The best contrast between masses and the hepatic parenchyma was in portal venous phase followed by arterial and delayed phase(p<0.01). In two hypervascular masses, the contrast was better in arterial phase. CONCLUSION: Portal venous phase of spiral CT is optimal in the detection of metastatic tumor of the liver. Arterial phase may be helpful for the detection of hypervascular metastasis. Delayed phase should be used restrictively.

Two cases of old unreduced dislocation of shoulder are reported. One was the posterior dislocation for six months with malunited fracture of humeral shaft in thirty degree lateral angulation. Her shoulder and arm aches with limitation of motion remaining only ten degrees in every direction but abduction in thirty degrees, The malunion of humeral shaft and shoulder were reduced surgically in result of eighty degrees abduction, seventy degrees flexion, sixty degrees extension and twenty degrees of external rotation with free of pain. Another case was an anterior dislocation for one year. Her range of shoulder motions are almost normal degree but brachial plaxus compression symptoms. Open reduction in practically Putti-Platt procedure was performed. She became completely free of brachial plexus symptom and ranges of shoulder motion are normal except about fifteen degrees less external rotation than preoperative condition. The surgical indication and the result of treatment were discussed for the the neglected cases of old unreduced dislocation of the shoulder.

Most patients who have spondylolysis dont's need surgical treatment. However, for the patients who have no response to conservative treatment, surgical treatment may be indicated. In 1970, Buck reported the operative technique that the used two screws between the pars defect and lamina followed by bone graft. In patients who have spondyloysis, pain in the back seems to be due to instability and irritation of nerve root by the abnormal motion of the loose neural arch and granulation tissue. For period of 7 years from May, 1984 to March, 1991, twelve patients with spondyloysis who had no response to conservative treatment were treated with Buck's operation and were analyzed. Following results were obtained: 1. The age of the patients was 24 years in average ranging from 14 to 40 years. 2. The level of the lesion was L5 in 10 cases, L4 in 2 cases. 3. Preoperative clinical feature included low back pain in 12 cases, refered pain in 2 cases. 4. Clinical sympotoms were improved in 83%, and the follow up result of the operation: excellent 16.7%, good 66.6% and poor 16.7%.

The purpose of this study was to estimate average lacrimal gland size on computed tomography in korean. The subjects were 137 Koreans who were checked orbital CT in Department of Ophthalmology, Soonchunhyang University School of Medicine from June 1990 to August 1994. The average width of lacrimal gland was 17.15 +/- 1.75mm, A-P length was 9.81 +/- 1.65mm and thickness was 4.57 +/- 0.99mm. The average width, A-P length and thickness of lacrimal gland were not statistically different between males and females(p>0.05).

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

We report a case of trichorrhexis nodosa in 16-year-old male. Multiple broken hair patches were seen on the both eyebrows. Scanning electron micrascopic findings revealed typical trichorrhexis nodosa; nodular swelling of hair shaft, loss of hair cuticle, longitudinal fissuring and fracture of hair cortex, and paintbrush effect on the side of fracture. Simple avoidance of trauma gave some regrowth of hair. Intralesinional administration of triamcinolone acetonide was not to be effective.
