A computer progrem which performs obstetric calculation on Clipper Language using the datas from ultrasonography was developed from personal computer. It was designed for fast assessment of fetal development, prediction of gestagional age, and weight from ultrasonographic measurements which included biparietal diameter, femur length, gestational sac, occipito-frontal diameter, abdominal diameter, and etc. The Obstetricel-Ultrasound data-Base Managemant System was tested for its performance. The Obstetrical-Ultrasound Data-Base Management System was very useful in patient management with its convenient data filing, easy retrieval of previous report, prompt but accurate estimation of fetal growth and skeletal anomaly and production of equation and growth curve for pregnant women.

The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

Colitis cystica profunda is a benign disorder in which a mucous cyst is located in the submucosal layer of, primarily, the pelvic colon and rectum. Radiologic reports of the condition are rare. We report the radiological findings of a case of colitis cystica profunda arising from the proximal ascending colon near the ileocecal valve, and causing intussusception. We also review the literature.

We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was performed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.

Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these se quences, have been termed microsatellite instability(MSI, genetic instability, replication errors, RER(+) phenotype). To date, at least four genes involved in DNA mismatch repair, hMSH2, hMLH1, hPMS1 and hPMS2, are thought to account for the observation of microsatellite instability in tumor from Hereditary nonpolyposis colorectal cancer (HNPCC) patients. The genetic defect responsible for the MIN+ phenotype in sporadic colorectal cancer, however, has yet to be clearly delineated. The purpose of this study was to determine the presence of MSI in sporadic cancer and to correlate its occurrence with clinicopathological parameters, we have studied six microsatellite loci by use of polymerase chain reaction amplification and denaturing polyacrylamide gel electrophoresis. We found that 20%(9 of 46 cases) sporadic colorectal cancers showed RER at two or several loci(RER+). Microsatellite instability was associated with location of the tumor in the proximal colon 66%(6 of 9 cases) and with poorly differentiated tumor phenotype 56%(5 of 9 cases). In order to better understand the role of somatic alterations within hMSH2 in the process of colorectal tumorigenesis, we examined the most conserved regions(codon 598~789) of this gene in nine patients with MIN spotadic colorectal cancer. 6 patient of RER(+) colorectal ca. patients had a polymorphism which was a T to C base change in the intron sequence at -6 position of the splice acceptor site at the 5'end of exon 13. This particular sequence variation is a polymorphism rather than a mutation which increase cancer susceptability. These data suggest that the genetic instability is detect ed in some colorectal cancers and play an important role in the pathogenesis of sporadic colorectal cancer.

Coronary spasm may be induced by a variety of physiologic and pharmacologic stimuli but specific receptor blockade has not been consistently shown to prevent the attacks. Most patients with variant angina respond well to treatment with calcium antagonists and nitrates. A small proportion of patients are refractory to this therapy. We report a case of the patient with a 9-year-history of variant angina who has been refractory to high doses of calcium antagonists and nitrates. The repeated addition of clonidine was consistently effective in abolishing both symptoms and objective evidence of myocardial ischemia in this particular patient.
