Hip arthrograghy is a valuable procedure for visualization of the intrinsic obstructive factors impeding closed reduction and for critical assessment of quality of reduction in developmental dislocation of the hip. The authors have analyzed 25 cases of developmentally dislocated hips in 24 patients who have been followed up for more than 1 year postoperatively by roentgenographies and arthrographies. Among them 16 cases in 16 patients who had been treated by closed reduction according to acceptable quality of initial reduction were studied to estimate a value of arthrography and to evaluate an outcome of closed rediction performed on the base of an arthrographic finding. The following results were obtained. 1. The frequency of the common arthrographic observations were assessed. Medial dye columns identifying the depth of reduction were observed 25 cases(100%), configuration of osteocartilaginous structures in 24 cases(96.0%), limbus in 24 cases(96.0%), and ligamentum teres in 18cases(75.0%). 2. Good closed reduction classified according to Race and Herring on initial arthrography was associated with rapid improvement of acetabular angle and the CE angle and low incidence of avascular necrosis, compared with adequate or poor reduction. 3. In cases of initial good and adequate reductions, initial AP arthrograms showed some dye filling shadows owing to folding or redundancy of lax joint capsule of the dislocated hip after reduction just lateral to the limbus, of which finding decreased markedly on the second arthrograms. 4. The widths of medial dye column decreased with time during the first postoperative 7 weeks by an average of 0.5mm in cases with initial good quality of reduction, 3.5mm in adequate reductions and 0.5mm in poor reductions. 5. In cases with adequate closed reduction on initial arthrogram, but without substantial decrease in width of medial dye column on the second arthogram the outcome was poor. In those cases with decrease in width of medial dye column on the second arthrogram compared with initial arthogram, the shorter the period of immobilization in a plaster cast was, the worse eventual result was. 6. We think that hip arthography is a helpful procedure for visualization of obstacle obstructing closed reduction and for determination of treatment modality in developmental dislocation of the hip.

Association of the hepatoid and choriocarcinomatous components in adenocarcinoma of the stomach is extremely unusual and raises a possibility of new approach understand the histogenesis of gastric hepatoid adenocarcinoma. This paper describes a Borrmann type III adenocarcinoma of the stomach with both choriocarcinomatous and hepatoid components in composite tumor pattern in a 50-year-old man. Tubular arrangement of differentiated embryonalcarcinoma was encountered in choricarcinomatous and hepatoid areas, which showed strong immunoreactivity to beta-HCG and AFP, respectively. The findings suggest that gastric adenocarcinoma may have a potential of differentiation toward embryonal carcinoma. from which both choriocarcinoma and hepatoid variant of gastric adenocarcinoma may develop by retrodifferentiation.

We reviewed a total of 36 cases of gastrointestinal carcinoid tumors during a period of ten and a half years at Seoul National University Hospital, looking at their histologic and ultrastructural features, as well as immunohistochemical results, then we correlated these with location. The primary sites of carcinoid tumors were rectum(39%), stomach(25%), appendix(22%), small intestine(8%) and colon(6%), in order of frequency. The predominant histologic types by organ were mixed and solid(A) types in all location, the solid type(type A) in the stomach, and tubular type(type C) in the rectum. Six out of 8 cases of appendiceal carcinoid were type A and the other two cases were mucinous carcinoid. Tubular adenoma or adenocarcinoma was associated with 36% of the rectal carcinoids, with one case of carcinoid in the small intestine, and one(11%) of the gastric carcinoids was found near an adenocarcinoma. Metastasis was found in one case of ileal carcinoid(100%), one case of cecal carcinoid, 3 of gastric carcinoid(33%) and 2 of rectal carcinoid(14%). Primary tumor size ranged from 1 to 7 cm. Tumor necrosis and endolymphatic tumor emboli were found in 57% and 43% of the metastatic carcinoids, respectively. PCNA index showed a borderline significant difference between metastatic and nonmetastatic groups(P value=0.063). The low prevalence of appendiceal carcinoid and the relatively high prevalence of gastric-rectal carcinoid may reflect a low chance of incidental appendectomy and frequent detection of gastrointestinal endoscopy.

BACKGROUND: Presently, it is well known that there are neurological and systemic complications after carbon monox-ide (CO) intoxication. Until recently, delayed-onset movement disorders after CO intoxication were rarely reported. We analyzed 32 patients with delayed onset movement disorders after CO intoxication. METHODS: We reviewed the medical records of 242 patients admitted to the Yonsei University Medical Center from January 1986 to December 1996 due to CO intoxication. Patients were analyzed with respect to movement disorders, onset, latency, and radiological findings. RESULTS: Among the 242 patients of CO intoxication, 32 (13.2%) patients had delayed-onset movement disorders. Of these, 23 (71.9%) had parkinsonism, 5 (15.6%) had dystonia, 3 (9.4%) had chorea, and 1 (3.1%) had myoclonus. The mean age of the patients was 46.66 +/-16.91 years. Among the 4 patients with CO intoxication occuring at age 17 or younger (Childhood group), 2 had parkinsonism and 2 had focal dystonia. The mean age of the Childhood group was 1 7 . 7 5 +/-6.99 years. Among the 28 patients with CO intoxication occuring at age 18 or older (Adult group), 21 (75%) had parkinsonism, 3(10.7%) dystonia, 3(10.7%) chorea, and 1(3.6%) myoclonus. Among the 3 patients with dystonia in the Adult group, 1 had focal dystonia and 2 had segmental dystonia. The mean age of the adult group was 50.79 +/-1 3 . 4 6 years. The mean latency between CO intoxication and the onset of movement disorders was 27.20 +/-27.94 weeks in the Childhood group and 9.60 +/-14.97 weeks in the Adult group. The mean latency between CO intoxication and the onset of movement disorders was 6.44 +/-6.76 weeks in parkinsonism, 41.76 +/-27.99 weeks in dystonia, 4.0 weeks in chorea, and 8.0 weeks in myoclonus. The mean latency in dystonia was longer than in the others. Among the 23 patients who underwent brain computed tomography, 12 (52.2%) had abnormal findings. Low density lesions were found in the globus pallidus (13.0%), cerebral white matter (13.0%), and both globus pallidus and cerebral white matter (17.4%). One (14.3%) patient showed cortical atrophy while another patient showed both cortical atrophy and low density in cerebral white matter. CONCLUSIONS: The development of a delayed-onset movement disorder after CO intoxication is not rare. In our research, the radiological findings of patients with delayed-onset movement disorders after CO intoxication were inconsistant. The findings revealed no correlations with the various types of delayed-onset movement disorders.

PURPOSE: This study was aimed to evaluate the recurrence rate of a giant cell tumor (GCT) of the bone. MATERIALS AND METHODS: The medical records of fifty four patients who were diagnosed with a giant cell tumor of the bone between March 1980 and December 2008 were analysed retrospectively. Among 54 patients, 27 were men, remaining 27 were women with the mean age of 33.1 years (range, 13-67 years). The mean duration of follow-up was 67.1 months. RESULTS: Twenty-one patients (38.9%) had a local recurrence. The mean time to recurrence was 21.5 months (range, 2-59 months). The local recurrence rate of the upper extremities was higher than that of lower extremities. According to Campanacci classification, patients with a grade I diseae had lower recurrence rate than those with grade II or III disease. There was no significant differences in the recurrence rates based on cryotherapy, the filling of bone cement or bone grafts and surgical margin. CONCLUSION: To prevent local recurrence of GCT of bone, curettage of the tumor and elimination of the remaining cells are more important than adjuvant therapy.

The degenerative spondylolisthesis is one of the most common causes of the prominent central and recess stenosis which are produced by the hypertrophy of the facet joints and anterior slipping of the posterior arch. The resulting neurogenic symptoms in the legs are the major causes of the surgical treatment in the degenerative spondylolisthesis and the complete decompression is indicated for these types of spinal stenosis. The decompression procedures performed in the degenerative spondylolisthesis makes more unstable and induce the late instability and the post

This case report draws attention to the possibility of symptomatic and asymptomatic intraarticular ganglion cyst which was situated adjacent to the insertion sites of the anterior or posterior cruciate ligament. In many reports and our case, MR imaging is recommended as the modality of choice in diagnosing method and the cyst, if encountered, is successfully treated with arthroscopie technique. We report one case of symptematic ganglion cyst of the posterior cruciate ligament with review of literatures.

In Albright's hereditary osteodystrophy (AHO) including the syndromes of pseudohypoparathyroidism (PHP) and pseudopseudohypoparathyroidism (PPHP), multiple areas of intracutaneous ossification are often encountered. The characteristic features are short stature, round face, short neck, obesity, cutaneous ossifications, and various skeletal anomalies including short metacarpal and metatarsal bones, curve of radius, and brachydactyly. The patient was a 10-month-old male infant. He presented slightly depressed erythematous hard plaques on the left upper chest and left thigh. We had taken biopsies from both skin lesions, confirming cutaneous ossification or bone formation. He also had the characteristic features of AHO. He had a history of admission due to patent ductus arteriosus and atrial septal defect. The laboratory results showed slightly decreased calcium, increased phosphorus and PTH levels. The patient received no specific corrective measures because his calcium and phosphorus levels were not far from normal values until newly developed similar skin lesions appeared.
