Congenital scoliosis is a structural deformity due to congenital anomaly of the spine. After Winter's report in 1973, congenital scoliosis is said to be progressive in 75% of cases, and 50% are rapidly progressive, serious and demand treatment. And thus, most of them need more aggressive and early treatment compared with idiopathic scoliosis. The prognosis depends on the type, angle and flexibility of the curvature, and the age of patient. The authors reviewed the results of operative treatment for the congenital scoliosis that had been treated from Jan. 1984 to Dec. 1993 at the orthopedic department of Yonsei University College of Medicine, and the results as follows. 1. The age distribution of the patients was from 2 years to 14 years, and the mean was 8.4 years. Five male patients and two female patients were operated. 2. The involved spinal segments of the primary curve were 2 cases of thoracolumbar, 3 cases of lumbar. There were two cases of double major curves. 3. According to MacEwen's classification, the types of vertebral anomaly were 4 cases of hemivertebra, 2 cases of miscellaneous and one case of wedge vertebra. 4. The levels of apical vertebra were each 1 case of T3, T9, Ll, L2, L4 respectively and each 2 cases of T12, L3 respectively. 5. The methods of operation included 1 case of resection of rib, 4 cases of posterior fusion, 1 case of combined anterior and posterior hemiepiphysiodesis and fusion, and 1 case of hemivertebra excision with spine fusion. 6. The curvature of spine on admission ranged form 10 degrees to 63 degrees, and the mean angle was 35.5 degrees. And, we followed up postoperatively from 1 year to 10 years, and the mean follow up period was 32 months. The final correction angles were from

A Radical gastrectomy can affect the dumping syndrome, reflux gastritis, injury of the autonomic nervous system and the small capacity syndrome and can cause some problems in the quality of life for post-gastrectomy patients. To minimize these complications in the treatment of early gastric cancer (EGC), various gastric-reduced operations have been discussed by gastric surgeons. A pylorus preserving gastrectomy (PPG) is a kind of reduced-gastric operation which preserves the distal portion (1.5 cm) of the gastric antrum and reduces postoperative complications such as the dumping syndrome and reflux esophagitis. However, a limitation of this operation is that complete lymph node dissection of the suprapyloric lymph node is undesirable for preservation of the pyloric branch of the vagus nerve. Nowadays, some reports state that this operation may be applicable in EGC confined to the mucosa and located at the gastric mid-body. (Purpose) This study was designed to evaluate the gastric function after PPG by using solid foods to obtain the gastric emptying time. (Materials and Method) From June 1995 to December 1995, we performed PPGs on 7 patients (4 patients with mucosal cancer, 2 patients with gastric ulcer and 1 patient with a leiomyoma) and Billroth I reconstruction in 7 patients (5 patients with mucosal cancer, 1 patient with advanced gastric cancer and 1 patient with gastric ulcer). To compare the gastric function between these two subgroups, we analyzed the lag time, T1/2 and the residual food after 100 min using 99mTc-tin-colloid-steamed eggs to obtain the gastric emptying time for the PPG group (n=7), the Billroth I reconstruction group (n=7), and the normal control group (n=7). A statistical analysis was done by using the Kruskal-Wallis test (Chi-square approximation). (Results) There were no differences in the amount of transfusion, the hospital stay, the operation time, and the body weight loss after operation between the PPG group and the Billroth I reconstruction group. The severe dumping syndrome and reflux esophagitis were found in one of the patients after Billroth I reconstruction, but were not found in PPG group. Statistically, there was no difference in T1/2 between the Billroth I reconstruction group and the PPG group; however, both lag times were longer than that of the normal control group. We also found that the residual food 100 min after oral intake was greater in both the Billroth I reconstruction and the PPG groups than in the normal control group. (Conclusion) Though both PPG and Billroth I reconstruction showed delayed gastric emptying, we found that PPG is superior to Billroth I reconstruction in lag time and in the amount of residual food after 100 min. We conclude that PPG is superior to Billroth I reconstruction in gastric motility, and if this operation is applied in indicated gastric cancer patients, post-operative complications, such as the dumping syndrome and reflux esophagitis can be reduced and the quality of life in post-gastrectomy patients can be increased.

OBJECTIVES: This study was conducted to investigate whether air pollution levels in Seoul have short term effects on respiratory disease outpatients. METHODS: We analyzed five air pollutants (CO, NOy, Oy, SOp, PMyp) and daily counts of outpatient for respiratory disease divided by age group ((15yrs, 15-64yrs, 65+yrs) during the period of July 1997-June 1998 using Generalized Additive Model(GAM). RESULTS: After controlling for seasonal trends, day of the week, week of the month, temperature and humidity, CO (RR=1. 041 ~ l. 051, 0-day lag) and NOy (RR=1. 024~1. 050, 3-day lag) were significantly associated with daily counts for respiratory disease in all age groups. 0, and SO, were associated, with a 3-day lag in the age group under 15 years (O RR=1. 047, 95% CI=1. 045- 1. 049 i SOp RR=1. 018, 95% CI=1. 017- l. 020) and with a 0-day lag in the age group 15 to 64 years (0, RR=1. 035, 95% CI=1. 032-1. 037; SO, RR=1. 037, 95% CI=1. 035-1. 039), in the age group over 65 years (O RR=1. 042, 95% CI=1. 033-1. 051; SO RR=1.029, 95% CI=1.022-1.036). PM was weakly associated, with a 1-day lag in the age group under 15 years (RR=1.011, 95% CI=1.010-1.013) and with a 0-day lag in the age group 15 to 64 years (RR=1. 021, 95% CI=1. 019-1. 023), in the age group over 65 years (RR=1. 025, 95% CI=1. 018-1. 032). In the two pollutant model, the magnitudes of the relative risk for CO, NOy and Oq were maintained, but SOy was not associated with daily counts for respiratory disease in the age group under 15 years after controlling for NO,. PMyp was not associated in all age groups after controlling for CO, so the association with PMyp in the single pollutant model might be confounded by CO. In this study, the impact Of PMyp on the respiratory disease was not large as compared with other pollutants. CONCLUSIONS: Air pollution in Seoul may increase the incidence of the respiratory disease, so more positive attention for the control of air pollution should be paid.

Hip subluxation and dislocation are common orthopaedic problems in children with cerebral palsy. Selective posterior rhizotomy(SPR) is a neurologic procedure aimed in reducing spasticity. Several recent studies have indicated a decrease in spasticity and functional improvement after SPR, and also decrease the tendency toward hip subluxation in children with cerebral palsy. This is a retrospective study to examine whether SPR halts hip subluxation. Between May 1994 and July 1996, 22 children below age of 5 underwent SPR. Twenty children were spastic diplegic types and 2 were mixed type and quadriplegic type respectively. Approximately 50-80% of L2-Sl level dorsal roots was cut, and 13 children had 50% of both Ll roots cut. Migration percentage score (MP) was used to determine progression of hip subluxation during the follow up period (12 36 mos.; Average 15 mos.). Of the total 44 hips in 22 patients, 45.5% (20 hips) improved, 34% (15 hips) remained unchanged, and 20.5% (9 hips) were worsened after SPR. Radiographic stability was achieved in 79.5%. Ll root cut rate (Ll SPR) was 55.5% for improved hips, 67% for unchanged hips, and 50% for worsened hips. Two patients had undergone orthopaedic procedure for progressive hip migration. Most patients experienced postoperative hip stability after SPR, but 20.5% were worsened and 2 patients had orthopaedic procedure. Also it is unlikely that Ll root involvement prevents progression of hip migration.

Approximately 10% of pheochromocytomas are malignant and its major criteria are tumor invasion of capsular blood vessel as well as metastatic invasion of other tissues. It is general rule that all resectable masses have to be removed surgically. However, there is no definite treatment modality about unresectable masses or microinvasive lesions. We experienced a case of 45 year-old male patient who was referred to our hospital for treatment of hypertension and headache. The plasma and urine catecholamine were increased above normal values and its metabolites also were increased. 131I-metaiodobenzylguanidine (MIBG) scan showed right adrenal mass and metastatic lesion of left iliac bone. This lesion was consistent with findings of the abdomen computed tomography (CT) and electron beam tomography (EBT) scan. We diagnosed this case as malignant pheochromocytoma. We removed primary tumor mass by wide excision and treated this patient with high dose 131I-MIBG. We report this case who shows good response to the high dose 131I-MIBG after surgery.

Advances in molecular biology have made it possible to understand the tumor biology of breast cancer at the molecular level and have revealed molecular targets for the therapy of breast cancer. Nowadays, targeting agents are used as mono-therapy or as combined therapy with other anti-cancer drugs for the treatment of breast cancer. Much more efforts is also being made in the development of better therapeutic agents targeting molecules having an important role in tumor biology. In this article, promising molecules for targeted therapy are reviewed for their roles in the pathophysiology and the treatment of breast cancer. We also introduce and summarize new preclinical agents, developed or on developing, with preliminary results from clinical trials. Given the progress currently being made, targeted therapy could become a main strategy for the treatment of breast cancer in the near future.

We report an unusual case of probable Creutzfeldt-Jakob disease (CJD) in hemodialysis patient. A woman 59 years of age with a past history of hypertension and end-stage renal disease presented with a stuporous state preceded by rapidly progressive cognitive dysfunction, myoclonus, and akinetic mutism. At first, the cause of the altered mental status was assumed to be uremic or hypertensive encephalopathy combined with fever. Proper managements, however, did not improve the neurologic symptoms. Diffusion-weighted magnetic resonance imaging revealed bilaterally asymmetric high signal intensity in both basal ganglia and cerebral cortices. Electroencephalography showed diffuse generalized theta-to-delta range slow wave and intermittent medium-to-high voltage complexes with a characteristic triphasic pattern on both hemispheres. Cerebrospinal fluid assay for the 14-3-3 protein was positive and diagnostic of CJD.

PURPOSE: This study was undertaken to investigate the prognostic significance of lymphatic invasion (LI), vessel invasion (VI), and neural invasion (NI) in gastric cancer and their correlations with other standard prognostic variables, such as the TNM stage. METHODS: The case histories of 100 gastric adenocarcinoma patients who had undergone a curative resection from 1992 to 1996 at Taegu Hyosung- Catholic University Hospital, Taegu, Korea were analyzed retrospectively. The Chi-Square test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rate were assessed using the log-rank test. The cox regression method was used for evaluation of independent prognostic significance. RESULTS: The 2-year survival rate was significantly lower (p<0.05) in LI (+) and NI (+) cases. The correlation between the T stage and LI, VI, and NI was statistically significant. Also, the correlation between the N stage and LI, VI, and NI was statistically significant. In the lymph node (+) group (n=43), the 2-year cumulative survival rate was higher in LI (-), VI (-), and NI (-) cases, but this result was not statistically significant. In the lymph node (-) group (n=57), the 2-year cumulative survival rate was higher in LI (-), VI (-), and NI (-) cases, but only the result for the NI (-) group was significant. Multivariate analysis demonstrated that LI, VI, and NI were not significant factors influencing the prognosis, although they were significant in the univariate analysis. CONCLUSION: This study identifies LI, VI, and NI as possible prognostic factor in gastric adenocarcinoma cases, but more careful research is needed.

OBJECTIVES: Many patients diagnosed with cancer suffer from various psychiatric symptoms such as depression, anxiety and insomnia as well as cancer itself. Patients with cancer are more vulnerable to possible adverse events of psychotropic medications. Although antidepressants are widely used among cancer patients, there is little information about tolerability of antidepressants. This study was conducted to compare tolerability of antidepressants in cancer patients referred for psychiatric consultation. METHODS: The participants were cancer patients who had been referred to psychiatrist for their psychiatric symptoms. We retrospectively analyzed the data of patients diagnosed with cancer from 9 general hospitals in Korea. The discontinuation rate for a 6 months period after treatment initiation for three antidepressants(Escitalopram, Mirtazapine, Paroxetine) were compared. RESULTS: Antidepressants were prescribed for 96.3% of subjects and Escitalopram 150(47.2%), Mirtazapine 92 (28.9%) and Paroxetine 76(23.9%) were prescribed frequently in order There were no significant differences in discontinuation rates among the three antidepressants during the 6 month period after initiation of pharmacotherapy. But there was a difference in discontinuation rates between inpatients versus outpatients(p<0.0001). CONCLUSIONS: In a naturalistic setting for the antidepressant treatment for cancer patients, it seems that there are no differences in discontinuation rates among these three antidepressants. It is therefore essential that such interactions are carefully considered when treating patients of antidepressants who already have cancer.

BACKGROUND: Serum thyroglobulin(Tg) is a valuable and sensitive tool needed in the follow-up of patients with differentiated thyroid cancer(DTC), but antithyroglobulin antibody(Anti-Tg), common in patients with DTC, can interfere with the assay for Tg. In this study, we evaluated the influence of Anti-Tg on the measurement of Tg using the immunoradiometric assay(IRMA). METHODS: In using ELSA-hTg in vivo test(CIS international, Schering, France), a solid phase two-site IRMA was used to measure Tg(23.5ng/mL, 62.5ng/mL) under the absence or presence of three concentrations of Anti-Tg(25U/mL, 50U/mL, 100U/mL). We also performed Tg measurement using patients serum that was mixed with patients serum containing high Anti-Tg. ANOVA and Scheffe tests were performed to evaluate the effect of Anti-Tg on Tg IRMA, and an inverse regression was made to calculate the level of Tg from measured Tg and used Anti-Tg levels and also to assess the degree of effect of anti-Tg on Tg IRMA. RESULTS: In measuring Tg using the standard solution, the presence of Anti-Tg resulted in a falsely suppressed Tg value. The IRMAs for 23.5ng/mL of the standard Tg solution resulted in 24.5+/-.1 ng/mL under no Anti-Tg, 11.8+/-.4ng/mL under 25U/mL of Anti-Tg, 7.7+/-.1ng/mL under 50U/mL of Anti-Tg, and 4.5+/-.4ng/mL under 100U/mL of Anti-Tg. IRMAs 62.5ng/mL of the standard Tg solution resulted in 65.9+/-.7ng/mL under no Anti-Tg, 36.3+/-.2ng/mL under 25U/mL of Anti-Tg, 23.7+/-.7ng/mL under 50U/mL of Anti-Tg, and 14.0+/-.0ng/mL under 100U/mL of Anti-Tg. (ANOVA test, p=0.000). The degree of suppression of the measured Tg value was positively correlated with the Anti-Tg level (Quadratic model regression, Sig T=0.000). The presence of Anti-Tg also resulted in a falsely suppressed Tg value for the Tg measurement using patient's serum. CONCLUSION: The presence of Anti-Tg could consist of the use of Tg as a tumor, therefore Anti-Tg should be measured in all patients diagnosed with DTC. The interpretation of the Tg level must be performed with extreme caution in patients with Anti-Tg.
