A fracture of the femoral neck in a young adult differs from the same fracture in an older patient in the following respects; 1. A relatively uncommon injury. 2. A significant difference in the severity of trauma. 3. A less satisfactory result. At the point of view, we studied the femoral neck fcartures in 15, 20- to 50-year-old patients. The aims were to analyze why these fractures occur in young adults, and what results can be expected after internal fixation. The results were as follows; 1. Common in men (3:1). 2. 80% (12/15 cases) of the fractures were caused by severe trauma. 3. The 3 cases (20%) were associated with the other fractures. 4. The factors infuencing the clinical results and complications in our study; a. Severity of trauma. b. Degree of displacement. c. Existence of posterior comminution. d. Time interval between accident and operation. 5. The multiple pinning got the more rigid fixation and diminished the rate of fixation failure. 6. All cases were achieved good to acceptable reduction. 7. Satisfactory functional results were achieved in 93.3%. 8. The rate of avascular necrosis was 15.4% (2/13 cases). It is concluded that the most of femoral neck fractures in younger patients occur because of the significant trauma. In our study, the incidence of avascular necrosis was not greater than in order patients. Therefore, to get as good a result as possible it seems important to perform the anatomical tion and rigid internal fixation with or without bone graft.

In children, the supracondylar fractures of the humerus are common in elbow region, and often associated with various complications and problems in treatment (ie,Volkmann's ischemic contracture, cubitus valgus or varus deformity, rotational deformity). The results of reduction can be measured by Baumann's angle, carrying angle, trochlea-capitellum angle, and displacement of distal radial styloid process on radiological study. So we have made experiments on the process which various three dimensional displacements reflected into two dimensional Baumann's angle and humerocapitellar angle. And we investigated the process of rotation, through various radiological studies by means of molded models of humerus. The results were as follows:l. In experiments, AP & lateral X-ray studies showed no change in rotation of proximal segment of fracture with fixed distal segment of fracture. 2. On the other hand, AP & lateral X-ray showed significant change, in rotation of proximal fracture segment with distal segment of fracture. 3. Supracondylar rotation angle(S.R.A.)depicted as the ratio of the length of proximal fracture width minus that of the distal fracture width in lateral view, to the length of distal fracture width in AP view minus that of the distal fracture width in lateral view. 4. According to the modified Mitchell result, S.R.A. to the result of treatment was average 7.6 degree in excellent group, 15.2 degree in good group and 29.3 degree in unsatisfactory group.

We report a case of acute intermittent porphyria presenting with variable symptoms and signs such as hypertension, polyneuropathy, syndrome of inappropriate secretion of antidiuretic hormone and cerebral infarction. A 47 year-old female patient entered hospital with abdominal pain followed by generalized seizure. She was diagnosed to have acute intermittent porphyria in consequence of Watson-Schwartz test and δ-ALA in 24 hours urine. She was managed with conservative treatment but died of respiratory failure.

A case of multiple myeloma combined with stomach cancer and related literatures were reviewed. A 67 year-old male patient entered the hospital with dysphagia and weight loss for 3 months. Peripheral blood examination revealed anemia with rouleaux formation. Total protein of the serum was 9.9 g/dl with hyperglobulinemia (albumin 2.7 g/dl, globulin 7.2 g/dl, A/G ratio 0.375). On the electrophoresis and immunoelectrophoresis of the serum, the abnormal protein with the pattern of monoclonal gammopathy (IgG-K type) was shown. There were multiple variable sized osteolytic lesions on skull X-ray and abnormal hot uptakes of rips on bone scan and result of rib biopsy was plasmacytoma. Gastrofiberscopy was performed to search for the cause of upper gastrointestinal bleeding, revealed stomach cancer, and the result of the gastric mucosal biopsy proved to be well-differentiated adenocarcinoma.

9.Epidermolysis Bullosa Acquisita.

A 40-year-old woman had a pruritic, vesiculobullous eruption of her face for 6 weeks with no evidence of systemic disease. A biopsy showed subepidermal blisters and dermal infiltrates of neutrophilic inflammatory cells. Direct immunofluorescence demonstrated thick linear deposits of IgG and C3 along the basement membrane zone. The cleavage plane was identified to be just beneath the lamina densa. Using Western immunoblots, the patient's IgG autoantibodies were found to recognize type VII proeollagen. Moderate starting doses of systemic prednisolone gave a good response for this patient with an early inflammatory form of epidermolysis bullosa acquisita.
