For the evaluation of the clinical and radiologicaI result in the surgical reduction and internal stabilization of the fracture-dislocations in the thoracic and lumbar area, the authors analysed the 39 patients who were treated with Harrington instrumentation supplemented by segmental sublaminar wiring and were follow up 24 months in average. l. Indications for the operation were: compression type with more than 50% of body wedging, bursting type with less than 30% of canal involvement without cord injury, fracture-dislocation type with instability and any type with complete cord injury. 2. Amount of fusion were 6 segments in 25 cases, 7 segments in 11 cases, 5, 8 and 10 segments in 1 case each. 3. Among 31 cases whose lumbar segment were involved in fusion, numbers of movable lumbar motion segments were three or less in 26 and two or less in 8. 4. Angular deformity were changed from 27 preoperatively to 8 postoperatively and to 12 at the end of follow up. Wedging amount of anterior vertebral height were 53% preoperatively, 23% postoperatively and 27% at the end of follow up. 5. External support were applied for 4 months in 35 cases; Taylor brace in 22, TLSO in 10 and body cast in 3. Ambulation was started within a week according to the general status. 6. Solid bony union were observed in 38 cases within 4 months period. Dislodgement of instrumentation and deep infection in one each patient were observed as operative complications. 7. Among 21 cases with cord injury symptoms, 18 cases with complete type showed no neurological recovery, but 3 cases with incomplete type showed complete recovery. It is concluded that the Harrington instrumentation with sublaminar wiring is an effective method of reduction and stabilization for the fracture and dislocations of the thoracic and lumbar spine. On the other hand, the operation is an extensive procedure with significant involvement of lumbar motion segments.

BACKGROUND: The purpose of this study was to evaluate the clinical and radiographic outcomes of internal fixation with locking T-plates for osteoporotic fractures of the proximal humerus in patients aged 65 years and older. METHODS: From January 2007 through to December 2015, we recruited 47 patients aged 65 years and older with osteoporotic fractures of the proximal humerus. All fractures had been treated using open reduction and internal fixation with a locking T-plate. We classified the fractures in accordance to the Neer classification system; At the final follow-up, the indicators of clinical outcome-the range of motion of the shoulder (flexion, internal rotation, and external rotation) and the presence of postoperative complications-and the indicators of radiographic outcome-the time-to-union and the neck-shaft angle of the proximal humerus-were evaluated. The Paavolainen method was used to grade the level of radiological outcome in the patients. RESULTS: The mean flexion was 155.0° (range, 90°–180°), the mean internal rotation was T8 (range, T6–L2), and the mean external rotation was 66.8° (range, 30°–80°). Postoperative complications, such as plate impingement, screw loosening, and varus malunion were observed in five patient. We found that all patients achieved bone union, and the mean time-to-union was 13.5 weeks of the treatment. The mean neck-shaft angle was 131.4° at the 6-month follow-up. According to the Paavolainen method, “good” and “fair” radiographic results each accounted for 38 and 9 of the total patients, respectively. CONCLUSIONS: We concluded that locking T-plate fixation leads to satisfactory clinical and radiological outcomes in elderly patients with proximal humeral fractures by providing a larger surface area of contact with the fracture and a more rigid fixation.

BACKGROUND: Intravenous urography(IVU) has long been accepted as the primary radiologic study for the diagnosis of renal colic. But the IVU does pose disks of contrast material reactions and exposure to radiation. Recently, IVU has been challenged as a first line modality and ultrasonography proposed as a replacement. We, therefore, felt obliged to re-evaluate the IVU, KUB and ultrasonography as diagnostic tools. METHODS: We evaluate the sensitivity and specificity of ultrasound, IVU and KUB in detecting urinary calculi in suspected acute renal colic, a prospective study of 69 patients, both sides of kidney and ureter, who visited urban university hospital emergency center from September 1997 to January 1998. Our sonographic criteria far a positive examination consisted of visualization of urinary tract calculus and/or hydronephrosis and/or urinoma. RESULTS: In Ultrasonography, the accuracy, sensitivity and specificity were 94, 94 and 94%. In IVU and KUB, they were 90, 81, 98% and 71, 43, 96%. CONCLUSION: Ultrasonography is very useful diagnostic tool in initial evaluation of acute renal colic.

A survey was performed in order to determine the infection status of the metacercariae of heterophyid fluke in two goby species, Boleophthalmus pectinirostris and Scartelaos sp., collected from Gangjin-gun, and Shinangun, Sooncheon-shi, Jeollanam-do, Republic of Korea. A total of three metacercariae of Heterophyopsis continua was found in only one B. pectinirostris (10.0%) from Gangjin-gun. Heterophyes nocens metacercariae were detected in 24 B. pectinirostris (96.0%) and 14 Scartelaos sp. (63.6%) from Shinan-gun. Heterophyopsis continua metacercariae were found in 11 B. pectinirostris (44.0%) and 21 Scartelaos sp. (95.5%) from Shinan-gun. Stictodora fuscata metacercariae were detected in 18 B. pectinirostris (72.0%) from Shinan-gun. No metacercariae were detected in 20 B. pectinirostris from Sooncheon-shi. From the above results, this study is the first to prove that B. pectinirostris and Scartelaos sp. serve as the second intermediate hosts of some heterophyid flukes in Korea.

Hepatic masses show different enhancing patterns in N bolus computed tomography: Hepatocellular carcinoma shows high-attenuation in the early enhancing phase and low-attenuation in the late enhancing phase, hemangioma shows peripheral dot-like high-attenuation in the early enhancing phase and central high-attenuation in the late enhancing phase, and metastatic cancer and cholangiocelluar carcinoma show peripheral high-attenuation rim in the early enhancing phase and central portion gradulally high attenuation in the late enhancing phase. but sometimes enhancing patterns of the hepatic masses are confuse. To evaluate the significance of the AFP level and HBsAg in differentiation of the hepatic masses, we retrospectively analyzed AFP level and HBsAg' in 228 pathologically or radiologically confirmed hepatocellular carcinomas, and 137 pathologically nonhepatocellular cacinomas. The results were as follows In hepatocellular carcinoma, AFP level above 20ng/ml was 77.8% and HBsAg positve was 72.6%. In nonhepatocellular carcinoma, AFP level above 20ng/ml was 3.7% and HBsAg positve was 16.1%. We concluded that AFP level and HBsAg are helpful to distinguish hepatocellular carcinoma from nonhepatocellular carcinoma, when IV bolus computed tomogram finding is uncertain.

Surface ECG findings in 29 patients with left isomerism were reviewed. Among the total 46 wave axis distributions, 25(54%) were abnormal axis, not originated from sinus node. Congenital atrioventricular block was found in 2 children. 6 patients showed the bradycardia and junctional escape rhythm intermittently or persistently. 4 of them, not related with heart surgery, were much older than 2 patients who showed these ECG findings after heart surgery. These ECG findings suggested the possibility of occurrence of sinus node or subsidiary pacemaker dysfunction in the patients with left isomerism, especially in the older patients. So we thought that electrophysiologic evaluation is necessary in some patients with left isomerism.

Recently many studies have shown the usefulness of computed tomogram in diagnosing abdominal mass when clinical and conventional radiologic examinations fail to reveal the nature of abdominal mass or the cause of abdominal distension. To evaluate the usefulness of CT in diagnosing neuroblastoma, we retrospectively analyzed computed tomographic findings of 16 neuroblastoma patients, who pathologically proved in Yeungnam University Hospital from 1986 to 1995. The age range of the patients studied were from 8months to 18years. The most frequent sith of origin was adrenal gland and the next was retroperitioneum. The presenting symptoms were palpable mass, abdominal distension, and abdominal pain.- The viewpoints of this analysis were tumoral calcifications, midline cross, shape, margin, internal structure, contrast enhancement patterns, major vessel involvement, and lymph node involvement. ':haracteristic CT findings were 'as follows: Fine dense curvillinear calcification within the tumor(56%), midline cross(50%), lobulation(75%), well-circumscribed margin(56%), cystic degeneration(56%), heterogeneous contrast enhancement(690/o), encasement of major vessels such as aorta, IVC and celiac trunk(50%), and paraaortic lymphadenopathy(87%). We conclude that these CT findings were very common and could be helpful in diagnosting and differentiation neuroblastoma in infant and children.
