A clinical review of 31 cases of multiple myeloma which were diagnosed by criteria of the SWOG between May 1983 and February 1990 at Yeungnam University Hospital was done. The results were as followings: 1. The peak incidence was in 7th decade and male to female ratio was 1.8:1. 2. The most common presenting symptom at first diagnosis was bone pain (58%), but fever, dyspnea, dizziness and palpable mass were also noted. 3. The distribution of laboratory findings as following diagnostic criteria of Southwest oncology group (SWOG): Plasmacytoma on tissue biopsy was noted 6 cases, bone marrow plasmacytosis with more than 10% plasma cells was 22 cases, monoclonal globulin spike on serum electrophoresis was 24 cases, lytic bone lesions was observed 22 cases. 4. Initial clinical stages were classified as 2 cases in stage I, 3 cases in stage II, 26 cases in stage III (84%). 5. Immunoelectrophoresis revealed the distribution of IgG 64%, light chain 22%, IgA 10%, Kappa to Lambda ratio of 1.1:1. 6. Hematologic & biochemical findings revealed anemia with <8.5% of hemoglobin in 42%, hypercalcemia with <10.6 mg% of serum calcium in 22%, azotemia >2.0 mg% of serum creatinine in 19%. 7. The multiple punched out lesion of bone x-ray examination were noticed skull (65%), rib (42%), L-spine (35%), pelvis (23%), T-spine (19%). The initial skeletal roentgenographic findings showed osteoporosis, osteolytic lesion and fracture in 55%, only osteolytic lesion in 23%, only osteoporosis in 10%. 8. Complications of multiple myeloma, such as 10 cases of renal impairment, 8 cases of infection, 16 cases of compression fracture of spine were observed.

Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre-and post- procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drain efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were lower than than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we though that it will be very helpful to the treatment of patients as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

Emphysematous pyelonephritis is a rare, life-endangering suppurative infection of the renal parenchyma and perirenal tissues. The disease is encountered mainly in the diabetic patient with or without ureteral obstruction and is characterized by the production of intrarenal and occasionally, perirenal gas. We report a case of emphysematous pyelonephritis, treated by left nephrectomy, in 55-year-old diabetic woman.

The retraction of anterior teeth could be performed more easier by inducing of skeletal anchorage system rather than by conventional method on orthodontic treatment. But, we wonder how effective the system draws well without anchorage loss and draws anterior teeth aside posteriorly, and if the system can reduce the time, in comparison with the anchorage of posterior teeth. For that reason we have studied on the subject of patients, who were required the maximum anchorage on orthodontic treatment and the cases without crowding. The subjects of the experimental group are 35 areas of 20 people who were inserted miniscrews after Mx or Mn 1st premolar extracted. Also, the subjects of the control group are 81 areas of 45 people who were not inserted miniscrews. Compared the anchorage loss of experimental group with control one, we could get the result that the anchorage loss of experimental group is 1.034+/-0.891mm and control group is 2.790+/-1.882mm(P<0.01). Compared the space closing time of experimental group with control one, we could get the result that the space closing time of experimental group is 369.40+/-110.81days and control group is 406.56+/-231.63days. But the result of comparing space closing time has no significance in statistics. We recognized that the experimental group is more faster than the control group in the canine retraction velocity from the result ; the speed of a experimental group has as much as 0.60+/-0.23mm/30days while the speed of a control group has 0.44+/-0.35mm/30days(P<0.05). So, we could convince that orthodontic miniscrew is used effectively in the cases required the maximum anchorage.

The contour of mandibular angle is important for facial esthetics in the oriental population, because the wide and square face is thought to have had an unhappy life. A prominent mandibular angle produces a characteristics quardrangle, coase, and muscular appearance. So, uni- or bi-lateral mandibular angle reduction is usually performed. However, there is little guideline for bi-lateral angle reduction. So, this study was to investigate the pattern of Korean mandibular angle for bi-lateral mandibular angle reduction as guideline. This study was included 66 adult men and women over 19 years old who are having the normal mandibular angle. We measured the posterior border, angle, and inferior border of mandible using cephalometric view. The results of study was as followed : 1. The ratio of posterior mandible was 96.6, 97.3% in male, and 103.0, 106.0% in female. 2. The ratio of mandibular angle(R1-Go/R1-R2) was 120.2% in male, and 117.3% in female. 3. The ratio of inferior mandible(D5, 6, 7, E, F, G/D4) was 97. 3, 90.9, 79.5, 65.2, 57.8, 46.9% in male, and 98.5, 91.2, 80.5, 67.6, 59.1, 50.2 % in female. The results of this study should be useful to decide accurate amount of reduction.

Dissecting aortic aneurysm is relatively rare in those under 40 years of age without high risk factors. After dissecting aortic aneurysm is occurred, the coronary artery is rarely perfused by false lumen. We present a thirty two-year-old man who showed Debakey type 1 dissecting aortic aneurysm with right coronary artery perfused by false lumen of ascending aorta and with congestive heart failure due to aortic insufficiency without discernible risk factor. Medical and surgical treatment (Modified Bentall's operation) were successfully performed. The pathologic report showed combined cystic medial necrosis. Now he is well tolerated and stable only with anticoagulation during follow up 18 months.

Screening is for the early detection and treatment of diseases in prior to development of symptoms, so that more favourable prognosis could be obtained. To evaluate efficiency of screening test for cervical neoplasms, we compared the histopathologic stages of asymptomatic cervical neoplasm patients diagnosed by screening test, with those of symptomatic patients confirmed by pathology. Total 1,120 cases of cervical neoplasm patient, diagnosed at Kang-nam St. Mary's hospital from Jan. 1990 to Dec. 1996, were reviewed by chart, and classified as asymptomatic and symptomatic group based on the presence of subjective symptoms on their hospital visit. Their histopathologic stages were analysed. The results were as follows, 1. From the total of 1,120 patient, asymptomatic group comprised 264 cases (25.5%). Asymptomatic proportion increased 15.3% in 1991 to 34.7% in 1996. 2. Mean age for the occurrence of cervical neoplasm was 44.3 +/- 10.4 years for the asymptomatic group, and 49.3+/-13.2 years for the symptomatic group, showing statistically significant differences(p=0.001). 3. Among the study subjects, 465 cases(45.0%) had CIS(carcinoma in situ), and 569 cases(55.0%) had invasive cancers. 4. Percentage of cervical neoplasm patient diagnosed at asymptomatic stages were 45.8% in twenties, 32.0% in thirties, 27.7 % in forties, 21.7% in fifties, 18.7% in sixties and 1.8% in above seventies, showing statistically significant differences according to age group(p=0.001). 5. In thirties, 87.2% of the asymptomatic patients were diagnosed as CIS and 45.0% of symptomatic patient were diagnosed as CIS. With increment of ages, CIS proportion were markedly decreased. 6. 76.9% of asymptomatic patients were diagnosed as CIS, and 34.0 % of symptomatic patients were diagnosed as CIS, suggesting screening test at asymptomatic stage can increase CIS proportion. 7. CIS proportion of asymptomatic patient was highest in thirties(40.4%) and 2nd highest in forties(34.0%). Screening test for cervical neoplasm should be actively carried out from the thirties.

Arteriovenous malformation in the gastrointestinal tract is very rare in children. However, when present they are frequently a source of either acute and massive, or chronic occult hemorrhage, and may be difficult to diagnosis. In reviewing Korean literature, only 2 cases has been reported in adults. We have experienced a rare case of arteriovenous malformation in a 1 year and 10 month-old female infant who presented with a history of two episodes of melena. Barium enema showed ill-defined mass shadow protruding into the cecum, and resection of cecum with ileocolostomy was performed. Pathologic diagnosis was a vascular malformation in the cecum, and related literatures were reviewed.

Choledochal cysts are congenital or acquired lesions of the biliary tree with a cystic dilatation of the bile duct. We experienced a choledochal cyst accompanying acute pancreatitis caused by anomalous pancreaticobiliary ductal union (APBDU) in a 2 year old boy. The choledochal cyst associated with APBDU is rarely encountered in the clinical field, and thus we report this case with the presentation of abdominal ultrasonogram, computed tomogram, and intraoperative cholangiogram. A brief review of choledochal cyst associated with APBDU is also presented.
