Hamartoma of the breast is a rare benign lesion presenting as palpable mass. They are, however, sometimes misdiagnosed by pathologist due to their resemblance to other benign or physiologic conditions of the breast. We report two cases of hamartomas of the breast. The clinical diagnosis was fibroadenoma in both cases. One patient was a 49-year-old woman presented with palpable mass for the duration of 5 months. Mammography showed a well demarcated round mass with homogeneous density which is slightly greater than the surrounding glandular tissue. Grossly it was a 3.5 3.0 2.0 cm sized round firm mass covered by thin fibrous tissue. Microscopically it was a well defined mass composed of variable amount of breast lobules, dilated ducts and adipose tissue surrounded by dense hyalinized connective tissue. The adipose tissue accounted for 30% of the entire lesion. Cellular atypism was not found. The other patient was a 18-year-old woman presented with palpable mass of the duration of 3 years, which was increased in size recently. Mammography demonstratesd a well delimited lobulated mass with lucent halo. Ultrasonography showed a well encapsulated low echoic mass admixed with high echoic areas. Grossly, it was a 4.0 4.0 2.0 cm sized well demarcated oval-shaped firm mass with translucent thin fibrous capsule.. Microscopic findings were similar to the former. The amount of adipose tissue was 20%.

The clinical study was made on 38 cases of the congenital megacolon who had been admitted to Dept. of Pediatrics and General surgery, National Medical Center from Jan., 1869 to Dec., 1977 We obtained the following results. 1. The sex ratio was 4.4 : 1, of male preponderance. 2. The onset of symptoms was within 1 week after birth in majority of the cases. 3. All patients were delivered at fullterm and the familial occurrence was not observed. The associated anomalies were a case of mongolism with congenital heart disease and of congenital hypertrophic pyloric stenosis. 4. In about half of the cases, the definitive diagnosis was made before the age of 6months 5. The clinical symptomes were abdominal distension, constipation, vomiting, diarrhea, visible peristalsis and weight loss in order of frequency. 6. Meconium passage was spontaneous in 41.2% and after digital examination or enema in 58.8%. 7. The majority of the cases(79%) were so called short segment type. One male patient was proved to be total aganglionic colon. 8. The definitive operation was performed in 18 cases, in which 14 cases(77.7%) received Swenson's procedure. The early complications were wound infection, leakage, fistula, pelvic abscess and the late complications were stricture, intestinal obstruction, enterocolitis, fecal impaction, malnutrition in order of frequency. 9. The total mortality rate was 23.7% and the operation mortality was 16.7%. 10. The results of one stage operation was somewhat better than two stage operation. 11. The follow up results were good in 83.3% of operated cases.

Three cases of successful pregnancy outcome after intensive care in the patients with rare mullerian anomaly of complete uterine septum, hypoplastic cervical duplication and longitudinal vaginal septum in infertility clinic are reported. These presented three cases are the reports of supporting the embryologic hypothesis of bidirectional mullerian development which fusion and resorption begins at the isthmus and proceeds simultaneously in both the cranial and caudal directions rather than the classical views of unidirectional(caudal to cranial) mullerian development. Thus, we present here three cases of rare mullerian anomaly and their pregnancy outcomes in an attempt to alert gynecologist to the possible occurrence of such a malformation. In 2 cases, successful pregnancy outcomes were achieved after abdominal or hysteroscopic uterine septotomy before pregnancy and in the last case, successful pregnancy outcome intensive obstetric care was achieved even under uncorrected uterine anomaly and complete removal of uterine septum resulted in uneventful postoperative courses at the same time of cesarean section.

Lawsonia intracellularis is not culturable with a standard bacteriologic culture. One step PCR assay as a clinical diagnostic method was developed for the rapid detection of porcine proliferative enteritis (PPE) caused by L. intracellularis. Primers were designed based on the p78 DNA clone of L. intracellularis. The one step PCR resulted in the formation of a specific 210-bp DNA product derived from L. intracellularis. The nonspecific amplification product was not detected with swine genomic DNA or other bacterial strains causing similar symptoms to L. intracellularis infection. The one step PCR was as sensitive as 100 pg of L. intracellularis genomic DNA. We applied this method to field specimens diagnosed as PPE by macroscopic observation. Of 17 mucosal scraping specimens, 16(94%) were identified as positive to PPE and 15(88%) of 17 feces specimens. These results suggest that the one step PCR can be used as a rapid diagnostic method for L. intracellularis infection.

Chronic ruptures of the patellar tendon are uncommon injuries. They are technically difficult to repair because of scar formation, poor quality of the remaining tendon, and quadriceps muscle atrophy and contracture. We report a case on the reconstruction of a chronic patellar tendon rupture. The reconstruction was performed 18 months after the injury, using an Achilles tendon allograft and reinforcing suprapatellar wire. At four weeks postoperative, the patient had attained 70degrees C flexion and 10degrees C extension lag. Nine months after the index procedure, the patient regained 130degrees C flexion and 5degrees C extension lag, and 85% quadriceps strength. The technique accomplished the preoperative goals of restoring quadriceps function and anatomic position of the patella as well as allowing early mobilization after surgery. Although this reconstructive procedure is technically demanding, the functional results obtained can be excellent. We recommend the use of this technique for chronic patellar tendon ruptures that cannot be primarily repaired.

In this paper, the real-time telemedicine system based on multimedia data was designed. In order to describe patients to medical specialists, the system included multimedia data. The prototype system designed in this paper effectively integrated multimedia components in a single computer, as well as compromise the compression, interface, medical imaging standards and modular software architectures. The mobile bed was manufactured to improve the movement of the system. Two experiments had been conducted to evaluate the technical functionality and clinical usability. Using the data compression and priority control, the telemedicine system transmitted multimedia data in real-time at the internet and the ethernet network. Inter-hospital experiments and Sang-Am World-Cup Stadium experiments demonstrate the feasibility to be effectively used.

PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.
