The recently proposed Bethesda system for cervical/vaginal cytology has made a standardization related to "atypia". In cellular changes due to inflammation or repair, the word "benign cellular change" has been suggested as a substitute for atypia. Terminology related to atypical cells may become standardized, but the cytologic criteria has not been well defined yet. We evaluated 160 cases of atypical squamous cells of undetermined significance(ASCUS) by the Bethesda System(TBS). Among 30,428 cases screened, a cytologic diagnosis of ASCUS was made in 498 cases(1.6%) and 160 cases were histologically verified. ASCUS was diagnosed based on nuclear enlargement and nonclassical signs of condyloma. The results are as follows: One hundred and twenty three cases(76.9%) revealed chronic cervicitis. Thirty seven cases(23.1%) demonstrated squamous intraepithelial lesion. Among intraepithelial lesions, condyloma and mild dysplasia were 28 cases(75.7%). Moderate and severe dysplasia were 5 cases(13.5%) and 4 cases(10.8%), respectively. It is concluded that patients with ASCUS should be colposcopically examined.

Giant cell tumor (GCT) occurs very unusually in the rib (less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic, benign looking osteoclast-like multinucleated giant cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei (average, 30 to 40 per cell, which were closely packed. The nuclei in giant cells were remarkably uniform and round to oval. The mononuclear, neoplastic stromal cells were elongated and spindle-shaped, There was no cytologically malignant portion in the tumor.

Although the ultrasonography has been regarded as a important procedure in the diagnosis of intraabdominalabscess, there were relatively few papers concerning the ultrasonographic findings of periappendiceal abscess.Nineteen cases of surgically proven periappendiceal abscess caused by perforated appendicitis were studied byultrasonography at the Kyung Hee University Hospital during last 34 months. The results were as follows; 1.Diagnostic accuracy of the real-time ultrasonography was 94.7%(18/19). There were only one false positive and onefalse negative. 2. The location of abscesses were ; periappendiceal 68.4%(13/19), pelvic 21.0%(4/19), subhepatic5.3%(1/19) and subphrenic 5.3%(1/19) in order of frequency. 3. Variable echo-patterns of abscesses wereencountered. But irregular, thick walled, posteriorly reinforcing, echo-free or mixed echo-patterns were mostcommon.

The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In atotal of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showedinternal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is notpossible in ultrasound. The possibility of mucocele shold be considered if cystic mass in right lower quadrantabdomen is observed in ultrasound.

Percutaneous drainage of 4 pancreatic abscesses and 5 pancreatic pseudocysts was performed under the guidance of ultrasonography or fluoroscopy. Clinical inprovement following the percutaneous drainage enabled surgical procedure in 2 of 4 pationts with pancreatic abscesses and obviated surgery in the other 2. In patients with pancreatic pseudocysts, recurrence have nat been observed for the last 3 years. Percutaneous drainage is a safe and effective procedure and could be the method of choice in the management of pancreatic pseudocyst that is symptomatic and enlarging. Percutaneous drainage could play a significant role in the management of the patients with pancreatic abscess.

The use of high-pressure air instruments has become more common. Consequently, there have been a number of cases of orbital emphysema caused by contact with high-pressure air. In this case, a 62-year-old male patient visited an emergency medical center after his left eye was shot by an air compressor gun that was used to wash cars. Lacerations were observed in the upper and lower eyelids of his left eye. Radiological examinations revealed orbital emphysema, optic nerve transection, pneumocephalus, and subcutaneous emphysema in the face, neck, shoulder, and mediastinum. Canalicular injury repair was performed, and the emphysema resolved. However, there was near-complete vision loss in the patient's left eye. Because most optic nerve transections occur after a severe disruption in bone structure, pure optic nerve transections without any injury of the bone structure, as in the present case, is extremely rare.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.
