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.

BACKGROUND: To find out characteristics and classification of toxic agents by clinical analysis of pediatric poisoning and to determine the clinical availability of grading by using MSPC score. METHOD: Subjects were patients under 15 years exposed to toxic agents, who visited Ajou university hospital emergency center from June, 1994 to October, 1997. The study was performed retrospectively. RESULTS: The subjects were 126 cases and male to female sex ratio was 1.2:1. Mean age was 29+/-30 months old. The most common route of exposure was ingestion, following contact, inhalation and bite. The most common reason was mistake by the patient, following mistake by caregiver, suicide attempt and accident. The MSPC score distribution of symptomatic patient was as follows; 1 point: 26 cases(63.4%), 2 point: 12 cases(29.2%), 3 point: 1 case(2.4%), 4 point: 2 cases(4.8%). The classification of exposed poison was as follows; therapeutic drugs: 29 cases(23.0%), non-therapeutic drugs: 97 cases(73.0%). The most common exposed poison was household products: 23 patients(18.3%) were admitted to hospital. CONCLUSION: There was statistically significant difference in the classification of poison, MSPC score, treatment modality at hospital, first follow up period after discharge between admitted group and non-admitted group. There was statistically significant difference in the reason of exposure, route of exposure, MSPC score, admission period according to patient's age. severity grading according to MSPC score is regarded as an available method to determine the modality of management.

OBJECTIVE: The goal of this study is to determine the efficacy of rapid karyotyping from fetal ascitic fluid. METHODS: In three cases of isolated fetal ascites diagnosed by prenatal ultrasonography, ultrasound guided fetal paracentesis and amniocentesis were performed and successfully obtained. Fetal karyotyping in each case at 29, 30 and 32 weeks gestation using modified lymphocyte culture method was conducted. RESULTS: The chromosomal analysis was successful within 72 hours and abnormalities were detected in two cases and revealed trisomy 21 in each case. Our study demonstrated that the majority distribution of white blood cells was lymphocytes which ranged from 2.1 * 10(6) cells/ml to 3.7 * 10(6) cells/ml and the cell density for culture was at least than 0.35 * 10(6) cells/ml. CONCLUSION: The use of ascitic fluid as a cell source to achieve rapid fetal karyotyping can be valuable when cordocenteis or amniocentesis would be technically more difficult, or when rapid result is required for planning of perinatal management at late second or third trimester gestational age.

It is the existence of a polarized distribution of ion transporters and channels which is thought to underlie the vectorial salt movement. The present study was performed to examine the expression and polarized distribution of Na+-K+-ATPase isoforms believed to be essential for salivary secretion in the rat salivary gland using immunohis-tochemistry. Na+-K+-ATPase alpha1 subunit immunoreactivity was prominent in the granular convoluted duct of the submandibular gland, and striated and excretory duct of three major salivary glands. The submandibular ganglion and postganglionic nerve fiber exhibited moderate immunoreactivity, whereas the intercalated duct and acinar cells of major salivary gland were weakly labeled. Na+-K+-ATPase beta1 subunit immunoreactivity was prominent in the granular convoluted duct of the submandibular gland, intercalated duct of the sublingual gland, acinar cells of the parotid gland, and striated and excretory ducts of major salivary gland. The submandibular ganglion, intercalated duct of the submandibular gland, and acinar cells of the sublingual gland exhibited moderate immunoreactivity, whereas acinar cells of the submandibular gland and intercalated duct of the parotid gland were weakly labeled. In these segments, alpha1 and beta1 immunoreactivity was expressed at the basolateral pole, and no apical expression was detected. These results suggest that major salivary glands are comprised of at least two structurally unique Na+-K+-ATPase isoforms, which are participated in primary saliva formation and transport.

A retrospective review of 102 patients with metastatic bone tumor seen at Hanyang University Hospital from 1986 to 1990 was performed. We analyzed the cases in the aspects of primary lesions, age and sex distributions, locations and number of metastatic foci, compared with those in the previous reports in Korea. l. 54.9% of the patients were male and 45.1% were female. The incidence of the metastatic bone tumors in female compared with the previous incidence before 1980's years was relatively increased. The peak age was in the 6th decade. The incidence younger than 50 years was decreased, and the incidence older than the 7th decade was relatively increased. 2. The main primary cancers were lung(40.2%), liver(11.8%), breast(10.8%), unknown(8.8%), and uterine cervix(6.9%) etc. In cases of lung cancer, the frequent histologic types were adenocarci noma, squamous cell carcinoma, and small cell carcinoma. 3. The vertebrae(56.9%), ribs(40.2%), femur(17.6%), pelvis(15.7%) were relatively frequent sites of metastasis which involved multiple metastasis. 4. Single metastasis(62.4%) was more frequent than multiple metastasis(37.6%). 5. In the primary cancers, the incidence in hepatoma of male was increasing, the incidence in lung cancer of female was relatively increasing, but the incidence in stomach cancer was decreasing.
