Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.

We examined the localization of neurofascin (NF) in the sciatic nerve of rat. In the myelinated fibers, neurofascin localizes strongly in the nodal axolemma except the small central cleft and also expresses in the paranodes, and weakly in the Schmidt-Lanterman incisures. In the paranodes, NF localizes around the axolemma and it expresses in the apposing membrane of paranodal loops. Axoplasm, compact myelin and cytoplasm of Schwann cell do not express NF at all. In the Schmidt-Lanterman incisures, NF is expressed weakly along the Schwann cell membrane. We propose that neurofascin may be a plasmalemmal integral protein of Schwann cell in the paranode and plays some important roles for the maintenance of axo-glial junctions at the paranode. It may also have some roles for maintaining the structure of Schmidt-Lanterman incisure and have some relations with proteins localizing in the node.

Alternaria cassiae Jurair & Khan was recorded on seeds of sickle senna(Cassia tora L.). Seed infection ranged from 25~45% in two samples. Developing roots and shoots turn brown and died in case of severe infection. Detailed descriptions were given on the habit characters of the fungus and on the morphology of conidiophores and condia. This is the first report of A. cassiae on seeds of Cassia.

We report a case of sebaceous hyperplasia showing linear arrangement in a 13-year-old girl. The lesion was found at birth and became prominent gradually. Multiple small discrete yellowish papules were arranged in a linear pattern on the temporal srea of the face. Unusual, incidental histopathologic finding was a sebaceous lobule lying in a dilated infundibular portion, which appeared to represent transfollicular extrusion of sebaceous lobule as a natural phenomenon.

While a giant cell tumor most frequently involves the distal end of the femur and proximal end of the tibia, involvement of the cervical spine is quite rare. Recently we observed a patient with a giant cell tumor affecting the sixth cervical vertebra. This is regarded as a clinically malignant tumor because its nature and difficulty in diagnosis and treatment We easily confirmed the extent of the lesion by CT scanning with Metrizamide. The treatment was palliative tumor ressection. This case of a giant cell tumor affecting the sixth cervical vertebra is reported with a brief review of the literature.

Since the first attemt of internal fixation not much more than a century ago, implants have come to play an important role in orthopaedic surgery. Yet little has been reported about complications which may result from implant surgery. During the period of May 1980 to April 1984, 32 cases of fixation failures were treated in the Department of Orthopaedic Surgery, Hallym College, Kang Nam Sacred Heart Hospital and results were obtained as follows: 1. The most common area involved femoral shaft, but the highest rate was distal femur. 2. The most common period of failure was between 2 to 4 months postoperatively. 3. The leading cause of failure was remaining defects at fracture site. 4. The authors recommend accurate reduction of fracture and bone graft, if necessary, adequate immobilization postoperatively and co-coperation of patient to avoid failure of implant.

The purpose of this study was to investigate the characteristiss of korean multi-rooted teeth extracted by periodontal disease. A total of 182 extracted multi-rooted teeth were examined. The distance from the cementoenamel junction(CEJ) to the root groove and from the CEJ to the root division was measured. The frequency of the root grooves were calculated. The results are as follows : 1. Distances from CEJ to the root groove were 1.53, 1.60mm for maxillary first premolars mesial, distal sides, 1.26, 1.38, 1.75mm for maxillary first molars buccal, mesial, distal sides, 1.38, 1.71, 1.41mm for maxillary second molars buccal, mesial, distal sides, 0.98, 0.99mm for mandibular first molars buccal , lingual sides and 1.28, 1.35mm for mandibular second molars buccal, lingual sides. 2. The frequency of the root grooves were 17.4, 30.4% for maxillary first premolars mesial, distal sides, 44.4, 84.1, 67.5% for maxillary first molars buccal, mesial, distal sides, 100, 90.3, 90.3% for maxillary second molars buccal, mesial, distal sides, 42.9, 77.8% for mandibular first molars buccal, lingual sides and 90.6% for mandibular second molars buccal, lingual sides. 3. Distances from CEJ to the root division were 6.8, 7.2mm for maxillary first premolars mesial, distal sides, 3.3, 4.38, 4.34mm for maxillary first molars buccal, mesial, distal sides, 3.67, 4.8, 4.07mm for maxillary second molars buccal, mesial, distal sides, 3.1, 3.89mm for mandibular first molars buccal, lingual sides and 3.2, 4.06mm for mandibular second molars buccal, lingual sides.
