In general. femoral neck fracture in young adult presents poor prognosis due to the high velocity injury, high angle shear fracture, and poor candidate for arthroplasty. In addition to the relative rarity of the injury, the high incidence of aseptic necrosis and nonunion have been reported in the management of these fractures. 25 cases of femoral neck fracture in young adult were treated with multiple pinning and analyzed at Sung-Ae general hospital from 1987 to 1994 after 28 months follow up in average with review of charts, X-ray and clinical result. There were 18 male and 7 female, 5 cases of them had significant polytrauma to other organs or skeletal system, authors tried to treat them as soon as possible to decrease the interval time between fracture and fixation (the average time was 39.7 hours.) Union occurred in all of Garden stage I (4 cases) and II (4 cases), but in Garden stage III (7 among 8 cases) and IV (7 among 9 cases) the union rate was lower. Average union time was 16.5 weeks. The incidence of complications (12%, 3 among 25 cases) was higher in displaced fractures group (Garden stage III, IV) and also in poorly reduced group of Garden’s alignment index. In conclusion, the prognosis of femoral neck fractures in young adult was related with mainly initial reduction and rigid fixation than the initial injury.

The method of treatment of acromioclavicular dislocation is controversial, and conservative and surgical treatment have been reported to be both successful. Recently, many surgeons tend to treat the acromioclavicular dislocation with anatomical reduction of acromioclavicular joint and rigid internal fixation because of many disadvantages of conservative methods. We report 24 cases of acute acromioclavicular dislocation treated with modified Phemister method from March 1989 to December 1992. The follow-up ranged from 12 months to 31 months with 16.5 months on average. The results are as follows. l. Among 24 cases, 21 cases are males and 20 cases are in 3rd decade to 5th decade. 2. The most common cause of injuries is falling down, followed by traffic accident. 3. Associated injuries are fractures in 5 cases, spleen rupture in 1 case. 4. Except 1 case with spleen rupture, 23 cases were treated within 2 weeks after injury. 5. Preoperative difference in C-C distance on stress view is 8.6mm on average, ranged from 6mm to 18mm. 6. Clinical results were excellent in 11 cases, good in 10 cases, fair in 2 case, and poor in 1 case. 7. Complications were pin migration in 1 case and symptomatic acromioclavicular arthritis in 1 case.

OBJECTIVES: Schizophrenia is a clinically heterogenous disease with a strong genetic component. Many studies have suggested that brain-derived neurotrophic factor(BDNF) is involved in the pathophysiology of schizophrenia. This study was performed to determine whether there is an association between BDNF Val66Met polymorphism and schizophrenia. METHODS: To identify any genetic predisposition to schizophrenia, we investigated the BDNF Val66Met polymorphism in 106 patients with schizophrenia and 147 normal controls with PCR-RFLP method. Statistical analyses were used to test the association between and BDNF Val66Met genotype and Schizophrenia. RESULTS: No association was found between BDNF Val66Met polymorphism and schizophrenia. No significant differences were found comparing the BDNF genotype distributions according to the age of onset, the number of admission and familial loading in schizophrenia. CONCLUSION: This result indicates that BDNF Val66Met polymorphism is not associated with schizophrenia. However, further studies with a large number of subjects are needed to confirm whether the BDNF gene is related to schizophrenia.

We report a case of coincidental pituitary adenoma and sphenoid meningioma. Computed tomographic scan had shown a large intrasellar rim enhancing mass and another well-enhancing mass with reactive bony thickening on the medial sphenoidal ridge. Magnetic resonance image revealed a snow-man shaped, expansile intrasellar mass, with small supra-sellar component, and a small enplaque-type enhancing dural thickening on the right medial sphenoidal ridge. Histopathologically, the intrasellar mass was diagnosed as pituitary adenoma and the other mass as secretory meningioma. We present clinical, radiological, and histopathological findings and review the reported cases of coincidental pituitary adenoma and meningioma without irradiation or trauma.

PURPOSE: The purpose of this study was to assess the usefulness of CT angiography(CTA) with spiral CT in evaluation of intracranial vascular lesions. MATERIALS AND METHODS: CTA and conventional angiography(CA) were performed in 22 patients with suspected intracranial vascular lesion. Nine patients had 10 aneurysms and 2 patients had arteriovenous malformation(AVM)s, while the remaining 11 patients had no vascular lesion. Twenty seconds after beginning injection of contrast media(100 mL with use of a power injector at the rate of 3 mL/sec), CT scanning(30-second continuous exposure and 60-mm length) was performed with a table speed of 2mm/sec and a section thickness of 2mm. The starting point was selected at the floor of the sella turcica. The resulting data were reformatted by MIP and SSD after reconstruction of 1 mm interval. For aneurysm, its size, shape, direction, neck and the relationship to adjacent vessels were compared to CA. RESULTS: The aneurysm diameter was ranged between 3mm and 20mm and all aneurysms were clearly visualized with CTA. CTA findings of the size, shape, direction, and neck of aneurysms and the relationship between aneurysm and adjacent vessels were well correlated with CA. In one case of aneurysm, calcification of the aneurysm wall was demonstrated on CTA. In one case of AVM, the nidus and its arterial supply and venous drainage were well visualized. In the other case of AVM, however, the feeding artery of AVM was not demonstrated on CTA(it was also unclear on CA). CONCLUSION: CTA with spiral CT may be useful in the evaluation of intracranial vascular lesion and valuable as a screening test for intracranial aneurysm.

We evaluated gastric emptying time (GET) by using Tc99m-sulfur colloid gastric emptying scintigraphy in 11 patients with CAPD (6 male, 5 female) and 14 healthy volunteers. We investigated the effect of dialysate dwelling on GET by studying twice, once without dialysate in the abdomen (drained) and once with 2 L of dialysate in the abdomen (full), and the relationship between body surface area (BSA) and delayed gastric emptying. 1) The mean of gastric emptying rate in 120 minute in patients with CAPD when drained (67.8+/-13.4%) was not different from that in healthy volunteers (65.4+/-8.6%) 2) The mean of gastric emptying rate in 120 minute when full (55.6+/-14.6%) was significantly lower than that when drained (67.8+/-13.4%) (P<0.05). In four of the 11 patients (36.4%), gastric emptying was extremely delayed from normal to abnormal range when full. 3) The BSA (1.5+/-0.11m2)of patients who had extremely delayed GET from normal to abnormal range was smaller than that (1.74+/-0.22m2) of patients who had minimal delayed or unchanged GET when full. This study showed the patient with CAPD had normal gastric emptying when drained, and that gastric emptying was delayed by dialysate dwelling, especially in the patients who has less than 1.5m2 of body surface area. Therefore, we suggest that intermittent nocturnal peritoneal dialysis or a small volume of dialysate may be considered for the patient with small body surface area based on the adequacy.

Cockcroft and Gault's formula is frequently used to estimate creatinine (Ccr) in clinical practice. To determine the accuracy of such estimation in Korean patients, we measured simultaneously, serum creatinine and 24-hour urinary creatinine excretion in 696 Korean patients (male:350, female:346). Measured Ccr was significantly different from estimated Ccr in several age groups and the decrease of creatinine excretion with age is less than Cockcroft and Gault's estimation. We assumed that this difference can be due to difference of the body habitus and difference of urinary creatinine excretion per body weight between different races. So we divided the sample population into two groups and derived the new formula in one group with regression analysis between age and 24 hour urinary creatinine excretion per body weight for estimation of Ccr as Cockcroft and Gault derived their formula and applied it to another group to compare the new formula with Cockcroft and Gault's formula in Korean patients. The new formula was Ccr (mL/min)=[ (260-age)x weight (kg)]/[160 x serumCr (mg/dL)] for male and Ccr (mL/min)-[ (236-age) x weight (kg)]/[180 x serum Cr (mg/dL)] for female. Predictive accuracy of the new formula was significantly better than the Cockcroft and Gault's formula in the other sample population and also in subgroup of the patients with azotemia.

PURPOSE: In spite of curative surgery and early postoperative intraperitoneal chemotherapy, the prognosis of patients with gastric cancer involving the serosal surface is poor. The aim of this study was to analyze p53 protein overexpression in these patients and to clarify the usefulness of p53 mutation as a prognostic indicator. METHODS: p53 protein overexpression was assessed by immunohistochemistry in 123 gastric cancer specimens. The correlation between p53 protein overexpression and clinicopathologic parameters and prognosis of the patients were analyzed. RESULTS: Overexpression of p53 protein was identified in 67 (54.5%) tumors and was more frequent in differentiated tumors than in undifferentiated tumors (67.4% vs. 46.8%; P=0.026). However, there were no statistically significant differences in the frequency of p53 protein overexpression according to age, sex, depth of invasion, lymph node metastasis, distant metastasis, pathologic stage, and Lauren classification. There was no statistically significant difference in 5-year survival rate according to the p53 protein overexpression (P=0.565). CONCLUSION: Overexpression of p53 protein could not predict the effectiveness of early postoperative intraperitoneal chemotherapy. Therefore, it could not be used as a prognostic indicator in patients with advanced gastric cancer who underwent gastrectomy and early postoperative intraperitoneal chemotherapy.

The primary mediastinal liposarcoma is very rare and only a few cases have been reported. We report a 25 year-old man who have had coughing and mild fever for a month. The simple chest X-ray and computed tomography of the chest revealed a huge mass in the right thoracic cavity that originated in the anterior mediastinum. Cytologic examination of the needle aspiration biopsy confirmed the diagnosis of a primary mediastinal liposarcoma. Through an exploratory right thoracotomy and a median sternotomy, the huge mass, lobulated and about 2,500 gm in weight, was extirpated. Mass was attached to a portion of the pericardium and diaphragm, but there was no invasion or metastasis to pleura and lung. The patient was discharged on the 12th postoperative day. He is continuously receiving radiotherapy.
