This paper reports a case of a patient aged 63 years who developed a delayed pneumothorax after thoracic paravertebral block (TPVB). TPVB is a non-invasive procedure that is known to be relatively safe. A 63-year-old female was admitted with back pain. TPVB T9–10 left was then performed. Two days after the procedure, she complained of dyspnea in the emergency room. X-ray showed a pneumothorax in her left side with partial left lung collapse. The pneumothorax was managed by surgical intervention, and an intercostal tube was inserted. The post-procedural X-ray showed a fully expanded lung. A chest tube was taken out after 72 hours. A delayed pneumothorax can occur after TPVB. Therefore, careful observation is required after this procedure.

Five cases of intracranial lipoma diagnosed by MR are presented. MR imaging was performed on a 0.2T permanent unit using T1 weighted, proton density-weighted, and T2 weighted spin echo sequences. In two patients, gadolinium-enhanced T1 weighted image was also obtained. The lipomas were located dorsolaterally to the splenium of the corpus callosum (n=1), inferior to the splenium (n=2), in quadrigeminal plate(n=1) and in the presumed corpus callosum area in the case of agenesis of corpus call?um (n=1). The size and shape of the lipomas were variable. No contrast enhancement was seen in post contrast study. Sagittal T1 weighted image appeared to be the most useful imaging plane for the demonstration of the relationship between the lipoma ad the adjacent normal structures. The Homogenous signal intensity paralleling the fat signal and the characteristic location of the lesion are considered to be helpful in the differential diagnosis from dermoid cyst or teratoma.

Platelet-derived growth factor(PDGF) is known to accelerate soft tissue fracture and periodontal bone healing, but little information is available for characterizing the healing of articualr cartilage. This study was designed to demonstrate the regeneration potential of pasteurized autogeneous osteochondral graft when PDFG was applied locally in vivo. Eighteen rabbits in two groups were used in the experiment. The free osteochondral fragment(1x1x1 cm) were taken from distal femur. The fragment were pasteurized in 65degrees C for 5 minutes. In experimental group(group II), the fragment were soaked in 0.25 mg/ml of recombinant human PDGF mixed 5 ml normal saline and reimplanted to the resected site, and followed with local administration of 0.25 mg/ml PDGF to knee joint. In control group(group I), the pasteurized fragment were reimplanted in the resected site without any treatments. The histologic characteristics of the transplanted autografts for three rabbits in each group were observed at 3, 5 and 7 weeks postoperatively. The results were as follows; Group II revealed the more favorable regeneration of articular cartilage, less arthritic changes and more mature arrangement of chondrocytes than group I. Even thought the cartilage is avascular and the regeneration capacity of pasteurized cartilage is severely limited, the regeneration of grafted articular cartilage is thought to be accellerated by increased newly formed blood vessels and soft tissues due to the diffusion of PDGF on grafted cartilage, and probably also by differentiation of mesenchymal cells in the initial stage of experiment. The results of this study suggest that local administration of PDGF could be used for the treatment of posttraumatic or degenerative arthritis and various cartilage damages.
