Percutaneous catheter drainage has been reported to bean effective method in the management of selectedpatients with abscess and fluid collection. Its high sucess rate and relatively low complications make theprocedure an alternative to surgery in the individual cases. During past two years percutaneous catheter dainagein 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology,Yonsei Universtiy College of medicine. Here the technique and auathor's results were summarized; 1. The total 25patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal andperirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid draingeunder guidence of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3.The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patientswere clinically improved. The catheter drainage was failed in 2 patients and 3 complications were developed. 4.The success rate of this procefure was 91.3%, failure rate was 8.7% and complication rate was 12%.

PURPOSE: To report a case of deterioration of a retinal arterial macroaneurysm after panretinal photocoagulation (PRP) for diabetic retinopathy. CASE SUMMARY: A 70-year-old woman visited our clinic for evaluation of diabetic retinopathy. Fundus examination and fluorescein angiography showed severe non-proliferative diabetic retinopathy and PRP was planned for the patient. In addition, the patient was found to have a retinal arterial macroaneurysm on the superotemporal area of the retina on her right eye. However, the lesion was small and was located far from the macula, causing no symptoms; thus we decided to observe the patient over a period of time. Two months after PRP, the patient revisited the clinic complaining of acute visual loss. Fundus examination showed vitreous and retinal hemorrhage and optical coherence tomography revealed subretinal fluid in the corresponding area. This was considered to be due to aggravation of the pre-existing macroaneurysm. Intravitreal Bevacizumab injection, C₃F₈ gas injection, and pars plana vitrectomy were performed. After absorption of the hemorrhage, barrier photocoagulation was performed around the retinal macroanerysm. The visual acuity improved and the retina remained stable through the most recent follow-up. CONCLUSIONS: We experienced the rupture of a preexisting retinal arterial macroaneurysm in an asymptomatic patient after panretinal photocoagulation. PRP in diabetic patients could aggravate retinal arterial macroaneurysms. Therefore, it is necessary to carefully examine the patient for retinal macroaneurysms when planning a PRP for diabetic retinopathy.

A 51-year-old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 6 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy, The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

We experienced a case of generalized granuloma annular e in a 68-year-old man. Many factors have been implicated in the genesis of this disease, but in this case no etiologic factors were identified. He was treated successfully with systemic corticosteroid for about l year.

The soleal line in 115 (left; 61, right; 54) cases of tibiae was studied morphometrically by the method of Mysorekar and Nandedkar. 1. The soleal line showed a uniform character throughout in 26 cases and a mixed characters in 89 cases. The bones showing uniform character were seen generally as a lineal line or wide line. 2. The soleal line having mixed characters divided into three parts. In the upper and middle thirds, the major type of line was wide line. In the lower third, the line was commonly seen as a lineal line. In about 12% of the bones examined the line was seen as a groove, particularly in the middle and lower thirds. 3. The soleal line commenced 1-2cm below the fibular facet In about 61% of cases. 4. The length of the soleal line was 10.5cm, and the ratio to that of the tibia was about 30%. The results of this study provide the characters of the soleal tne of the tibia in Korean. The soleal line, unlike the textbook description, generally shows mixed characters of a line.

Letterer-Siwe disease is one of Langerhans cell histiocytosis, with Hand-Schuller-Christian disease and eosinophilic granuloma, characterized by proliferation of Langevha is cell. The clinical course of Letterer-Siwe disease is acute fulmunant of casionally fatal, involving skin and many other internal organs, such as the lymph node, liver, spleen, ung and bone. We present 3 cases of Letterer-Siwe disease with characteristic cutaneous findings and revealed Langerhans granules by imrriunohistochemical stain and electronmicrc scopic examination. All patients died in spite of combined chernotherapy.

The purpose of this study was to examine the frequency of dehiscence bone defect on peri-implant and to compare the difference between resorbable membrane and non-resorbable membrane in bone regeneration on peri-implant. Amomg the patients, 22 patientswho have recieved an implant surgery at the department of Periodontics in Dankook University Dental Hospital showed implant exposure due to the dehiscence defect and 27 implants of these 22 patients were the target of the treatment. Gore-Tex(R) and Bio-mesh(R) were applied to the patients and treated them with antibiotics for five days both preoperatively and postoperatively. Reentry period was 26 weeks on average in maxilla and 14 weeks on average in mandible. The results were as follows: 1. Dehiscence bone defect frequently appeared in premolar in mandible and anterior teeth in maxilla respectively. 2. Among 27 cases, 2 membrane exposures were observed and in these two cases, regenerated area was decreased. 3. In non-resorbable membrane, bone surface area 9.25+/-4.84 preoperatively and significantly increased to 11.48+/-7.52 postoperatively.(P<0.05) 4. In resorbable membrane, bone surface area was 14.80+/-8.25 preoperatively and meaningfully widened to 17.61+/-10.67 postoperatively.(P<0.05) 5. The increase of bone surface area in non-resorbable membrane was 2.23+/-3.38 and the increase of bone surface area in resorbable membrane was 2.80+/-3.00 ;therefore, there was no significant difference between these two membranes(P<0.05). This study implies that the surgical method using DFDB and membrane on peri-implant bone defect is effective in bone regeneration regardless the kind of the membrane, and a similar result was shown when a resorbable membrane was used.
