While the microbiology of cellulitis in the pediatric population and systemic diseases(DM, Cirrhosis, etc) is well known,the causative bacteria and clinical aspect of cellulitis in young adults are less descrihed. this study was undertaken to identify the causative organisms and clinical aspect of adult cellulits. We analysed 121 medical records of 115 young adult patients with cellulitis who had been admitted at the department of orthopaedic surgery, National Police hospital from Jan. 1994. to Dec. 1996. The results were as follows. 1. The age of patient was between 21 yrs and 25 yrs, and the sex of all patients was male. 2. The lower leg and foot were the most frequently involved site of cellulitis as 92 cases(74.2%). 3. The potals were suspected in 65 cases(56.5%),of them, traumas were detected in 43 cases(66.1%), non-traumatic skin lesions in 23 cases(33.9%). 4. In most cases, initial systemic symptoms (fever, chill, headache, etc.) and local symptoms (local heating, tenderness, etc.) were found. 5. The laboratory findings revealed leukocytosis in 19%, elevated ESR in 94%, positive CRP in 80%. 6. Microorganism were detected in 16 of 38 pus cultures. Gram positive microorganisms were detected in 15 of 16 cases culture positive. 7. 6.7% of patients with cellulitis experienced recurrence in same lesions. In conclusion, the retrospective analysis of 115 young adult patients with cellulitis showed that primary cause of young adult cellulit was circulatory disturbance and lymphatic obstruction of the lower extremities most often involved by trauma. therefore, supportive treatments such as rest,elevation,ice packs are considered prior to antibiotic treatment.antibiotic treatment aimed at gram-positive cocci appears to be sufficient.

Tumor and tumor-like lesion of the patella are extremely rare. The following have been reported: giant cell tumor; osteoblastoma; osteoid osteoma; chondroblastoma; solitary osteochon droma; chondroma; ganglion; simple bone cyst; aneurysmal bone cyst; hyperparathyrodism (brown tumor); malignant lymphoma; haemangioendothelioma; haemangima; primary osteosarcoma; plasmocytoma and metastases. Chodroblastoma in patella were very rare and first repoted by Jerone Cohren in 1963. On review of our literatures, we could not find reported case in Korea. The purpose of this paper is to present an unusual case of chondroblastoma of the patella.

Early stage osteonecrosis of femoral head is a major therapeutic dilemma in orthopedics. Many joint preserving treatment modalities have been proposed, but none of them is entirely satisfactory. Among them, core decompression has been widely performed. The results of twenty two core decompression procedures that were performed for osteonecrosis of the femoral head in fifteen patients were retrospectively reviewed to evaluate the effectiveness of the procedure. From January 1990 to December 1993, we had treated twenty two cases of the osteonecrosis of femoral head. The average follow-up was 31 months, ranging from 12 months to 58 months and the average age at operation was 39.6 years, ranging from 21 to 58 years. By Ficat-Arlet stage, the stages I were 1 case,IIa 6 cases, IIb 7 cases and III 8 cases. The functional and radiological evaluation was done preoperatively and at final follow up by the Harris Hip score and Ficat stage. The results were as follows. The improved cases were 10 cases and the progressed were 12. Radiologically, none of 1 hip(0%) with stage I, two of 6 hips(33%) with stage IIa, four of 7 hips(57%) with stage IIb, and six of 8 hips(75%) with stage III have progressed. Mean preoperative Harris Hip score was 57 points and it improves to 69 (the improved 13 cases; 85, the progressed 9; cases; 49)at final follow up. In six of the progressed 9 cases, the arthroplasties were performed. Among them, five cases are being observed. In conclusion, the core decompression is not only highly effective in preventing further change in femoral head, but also relieving pain and delaying time for arthroplasty at late stage osteonecrosis of femoral head.

MR arthrography is a useful modality for evaluating the labrocapsular ligamentous complex (LCLC) of the shoulder. This study was performed to describe normal anatomic variations and pitfalls in image interpretation related to evaluation of the LCLC. MR arthrogram of 56 shoulders in 41 asymptomatic young, active, male volunteers were prospectively reviewed to evaluate the labral shapes, capsular insertions and images which may mimic the lesions of glenohumeral instability. The anterior and posterior parts of the labra, respectively, varied in shape: triangular (72%,36%), round (13%,35%), cleaved (8%,1%), notched (2%,0%), flat (5%,24%), and absent (0%,4%). The anterior and posterior capsular insertions, respectively, varied in site: Mosely and Oevergaard type I (82%,62%), type II (13%,36%), and type III (5%2%). A number of pitfalls in image interpretation were discovered. Articular cartilage undercutting the labrum (29%) and middle glenohumoral ligament in proximity to anterior labrum (5%) simulated a labral tear. Joint fluid interposed in the central, superior portion of the sublabral sulci (25%) simulated a SLAP lesion. Synovial fold (38%) in the axillary pouch resembled a loose body. Knowledge of normal variations and pitfalls in MR arthrogram image interpretation of labral-capsular-ligamentous complex will help the orthopedist to accurately detect debilitating derangements associated with the glenohumeral instability.

PURPOSE: Transcatheter arterial chemoembolization (TACE) and subsequent percutaneous ethanol injection (PEi) was attempted in 8 patients with 9 hepatocellular carcinomas (HCCs) for complete tumor necrosis of HCCs less than 5cm in greatest diameter. MATERIALS AND METHODS: PEI was performed with 2-8ml of absolute (99.9%) ethanol two weeks after TACE under CT or ultrasound guidance. For each patient PEI was done twice to four times within 4-10 days of each procedure. After completion of a series of PEI, follow up examination (range:3 months-l.5 year period) was done with angiography, CT or ultrasound and correlated with serum alpha-fetoprotein (AFP) level. RESULTS: On follow up anglograms, the lesions completely disappeared or decreased in size without tumor vessels or staining in 5 of 6 patients. On follow up CT of 6 patients, the lipiodol-laden HCCs were surrounded by non-enhancing low density and the losion sizes were slightly decreased or not changed. These are suggestive of necrosis of tumor itself and adjacent liver parenchyma. The tumors could not be detected on follow up ultrasound examination in 2 patients. Serum AFP was decreased in 7 patients and was well corresponded to the results of imaging modalities. CONCLUSION: The authors concluded that the combined TACE and PEI is an appropriate treatment for small HCCs having high surgical risks.

OBJECTIVES: To evaluate the patterns of changes in maternal weight and fetal weight discordance in twin pregnancies during consecutive gestational periods. METHODS: A retrospective chart review was done for a total of 148 twin pregnancies taken care of throughout pregnancies between February 2002 and May 2004. They were divided into two groups; group A consisting of 109 cases without postnatal complications and with no more than 25% twin weight discordance at birth, and group B consisting of 39 cases with more than 25% twin weight discordance. Both ultrasound examination and maternal weight measurement were conducted in the three gestational intervals; between prepregnant times to gestational age 18 weeks, between gestational ages 18 to 28 weeks, and from gestational age 28 weeks to delivery. RESULTS: Except for maternal weights, none of the pregnancy factors such as maternal age, parity, gravity, height, prepregnant weight, duration of pregnancy, natural or artificial pregnant status, gender and chorionicity showed any significant difference by means between the two groups. The maternal BMI of the group A vs. the group B at the first, the second, and the third period were 0.53+/-0.10% and 2.01+/-1.28%, 2.97+/-0.11% and 4.84+/-1.23%, and 3.29+/-0.16% and 2.15+/-0.63% respectively. Inter-twin weight discordances between the two groups were 8.29+/-0.67% vs. 11.26+/-1.25 %, 7.79+/-0.05% vs. 11.03+/-1.36%, and 9.07+/-0.55% vs. 32.79+/-1.13%, respectively. CONCLUSIONS: Although several factors that affect twin weight discordance may be considered, we showed that the pattern of maternal weight gain during the gestational period is associated with the estimated values of twin weight discordances in the first gestational period.

The in vivo photosensitizing efficacy of chlorophyll derivatives(CpD), which had been developed as a new photosensitizer, was compared with that of hematoporphyrin derivatives (HpD). A murine tumor model implanted subcutaneously with S-180 cells on the abdomen was used. The CpD or HpD was administered by intratumoral injection, and light of appropriate wavelength was irradiated on the tumor areas for 10 minutes at 1h and 24h or 24h and 48h after the injection of photosensitizer. When CpD was injected, the early irradiation group (1h and 24h) showed a 100% tumor cure rate; however, the late irradiation group (24h and 48h) showed a 60% tumor cure rate (p less than 0.01). This showed that the early irradiation with light after injection of CpD was an important factor for obtaining better results. With HpD, there was no difference in tumor cure rate between early (1h and 24h, 80%) and late irradiation (24h and 48h, 80%) groups. Thus, in early irradiation groups, the tumor cure rate using CpD (100%) was superior to that of HpD (80%) (p less than 0.05). However, in late irradiation groups, the tumor cure rate using CpD (60%) was inferior to that of HpD (80%), but this difference was not statistically significant (p greater than 0.1). Pathologic sections of these tumors were made before treatment and 48h and 3 weeks after treatment. These showed geographic necrosis at 48h after treatment and no viable tumor tissue at 3 weeks after treatment. Our results showed that CpD was as effective as HpD as a photosensitizer for in vivo photodynamic therapy.

About 90% of primary gastrointestinal lymphomas originate from the B-cell and less than 10% from the T-cell. In respect of anatomical location, the stomach is the most common site of gastrointestinal lymphomas followed by the ileum, colon, and rectum. However, esophagus and duodenal lymphomas are infrequently involved. Primary T-cell lymphoma of the duodenum is not common and peripheral T-cell lymphoma of the duodenum is very rare. In Korea, there has been no case report of peripheral T-cell lymphoma which simultaneously involved the stomach and duodenum. In this report, we present a case of primary peripheral T-cell lymphoma of the duodenum and stomach. A 63-year-old man was hospitalized complaining of weight loss of 15 kg and dyspepsia for 2 months. Esophagogastroduodenoscopy showed a large annular infiltrative lesion in the descending portion of the duodenum. At the posterior side of the upper body of the stomach, an ill-defined, broad, flat, and infiltrative lesion was also noted. Microscopic examination of the biopsy specimen showed that atypical bizzare lymphocytes infiltrated the mucosa of the duodenum and stomach. The lymphocyte was positive for CD3, CD5 and negative for CD20, CD23, and CD56 by immunohistochemistry. We made a diagnosis of primary peripheral T-cell lymphoma of the stomach and duodenum. We report a case of peripheral T-cell lymphoma of the stomach and duodenum with a review of the literature.
