Partial knee ankylosis is a recognized complication following open operative procedure, trauma and disease processes about the knee. It can result from the formation of intraarticular adhesion and contracture of the capsule as well as the shortening or adhesion of the quadriceps mechanism. Physical therspy and occasionally manipulation under the anesthesia may improve the results, but performed late, these methods will be useless. This is a review of 30 patients who had severe limitation of motion in the knee joint following open operative procedures or trauma about the knee and who were treated by the percutaneous release of adhesions under the arthroscopic control. The following results were obtained; There were 17 males and 13 females, and the age of release ranged from 23 to 69 years old (av. 42.8years old). The interval between arthroscopic adhesiolysis and the last follow-up evaluation ranged from 6 months to 5 years and 7 months(av. 23 months). The interval between the last open operative procedure or trauma and arthroscopic adhesiolysis ranged from 3 months to 4 years(av. 15 months). The average preoperative knee ROM was 38.8°the postoperative ROM was 121.1°and the average final knee ROM at follow-up was 102.6°So the average loss of ROM was 18.5°The arthroscopic adhesiolysis seems to be applied to the various conditions of the partial knee ankylosis and the results are better than the other surgical procedures when it was performed early enough.

In the treatment of Tb.knee, the preservation of mobility is an important issue, there are many difficulties due to pain and swelling in the trial of early ROM exercise, and various problems such as the recurrence of Tb. lesions, delayed wound healing and draining sinus formation. We analysed 30 cases of Tb. knee treated with synovectomy during 10 years since March, 1979. In Group I (25 cases), early ROM exercise were started about 4 weeks after synovectomy. And in Group II (5 csses), arthroscopic adhesiolysis was performed after minimum 6 month immobilization and chemotherapy following synovectomy. We compared the two Groups and the results were as followings: 1. Male was 15 patients and female was 15 patients, the average age was 28.1 years. 2. The average follow-up period was 18.3 months. 3. In Group I, the ROM exercise was performed before 4 weeks in 9 cases and after 4 weeks in 16 cases postoperatively. The average final ROM was 68.9° 4. Draining sinus formation was in 4 cases in Group I. 5. In Group II, arthroscopic adhesiolysis was performed in 5 cases after synovectomy and chemotherapy for average 8.8 months ranging from 6 to 14 months. 6. The average final ROM at follow-up was 111° in Group II. 7. In a case with the severe involvement of bone and cartilage in Tb. lesion at the synovectomy, ROM was reduced gradually to 50° after arthroscopic adhesiolysis. We could gain ROM of 120° by TKR. 8. Draining sinus formation was not found in Group II.

Transvenous coil embolization has been successfully applied for the treatment of cerebral dural arteriovenous fistulae. Unfortunately, the technique can not be applied in cases of poor or absent venous access route to the fistula, the situation of which is not uncommon. Transarterial embolization can be performed as an alternative method. However, the method usually ended in partial embolization of the fistulae because of the multiplicity of the dural feeders and anfractuosity of the feeders. Use of liquid embolic material, such as glue in transarterial embolization generally regarded as not conventional. Recently we experienced a successful embolization using a newly introduced liquid embolic material, Onyx in a case of transverse-sigmoid sinus dural arteriovenous fistula which was failed to be embolized with transvenous approach.

Embolization of an aneurysm at the proximal A1 segment of the anterior cerebral artery (ACA) is technically challenging. We treated four consecutive patients with unruptured aneurysms at the proximal portion of the A1 segment of the ACA. We tested various microcatheter tip shapes before we successfully embolized a lesion with a zigzag-shaped microcatheter tip, which was made by steam shaping. The shape of this microcatheter tip resembled the letter "Z", had a relatively long distal straight segment and was helpful in prompt catheterization of the aneurysm sac and stable placement of the catheter and delivery of coils.

BACKGROUND: The skin has many important functions such as protection, preservation, temperature regulation, and vitamin D synthesis. It is composed of a variety of cell types including keratinocytes, melanocytes and fibroblasts. OBJECTIVE: We attempted to compare the gene expression profiles between keratinocytes, melanocytes and fibroblast, using cDNA microarray. METHODS: Keratinocytes, melanocytes and fibroblasts were primary cultured from five foreskin specimens. Total RNAs were extracted and pooled to reduce the individual variations, and then used for cDNA microarray. RESULTS: Total 12,028 genes were selected as the reliable genes whose expression was detected in at least one of the three cell types. By comparing the relative expression levels with cutoff limitation as a fourfold change, we obtained 126 fibroblast-specific, 179 keratinocyte-specific and 173 melanocyte-specific genes, many of which are known to be characteristically expressed in each cell type. In addition, we identified many genes whose skin-specific functions have not yet been determined. CONCLUSION: Our data provide important information on which to base further investigation into the specification of skin cell types.

BACKGROUND: The reconstruction of ankle and heel defects remains a significant problem for plastic surgeons. The following options exist for reconstructing such defects: local random flaps, reverse flow island flaps, and free flaps. However, each of these methods has certain drawbacks. Peroneal artery perforators have many advantages; in particular, they are predictable and reliable for ankle and heel reconstructions. In this study, we report our clinical experience with peroneal artery perforator-based pedicled flaps in ankle and heel reconstructions. METHODS: From July 2005 to October 2012, 12 patients underwent the reconstruction of soft tissue defects in the ankle and heel using a peroneal artery perforator-based pedicled flap. These 12 cases were classified according to the anatomical area involved. The cause of the wound, comorbidities, flap size, operative results, and complications were analyzed through retrospective chart review. RESULTS: The mean age of the patients was 52.4 years. The size of the flaps ranged from 5x4 to 20x8 cm2. The defects were classified into two groups based on whether they occurred in the Achilles tendon (n=9) or heel pad (n=3). In all 12 patients, complete flap survival was achieved without significant complications; however, two patients experienced minor wound dehiscence. Nevertheless, these wounds healed in response to subsequent debridement and conservative management. No patient had any functional deficits of the lower extremities. CONCLUSIONS: Peroneal artery perforator-based pedicled flaps were found to be a useful option for the reconstruction of soft tissue defects of the ankle and heel.

One of the main reasons for the soaring interest in acute ischemic stroke among radiologists is the advent of new magnetic resonance techniques such as diffusion-weighted imaging. This new modality has prompted us to seek a better understanding of the pathophysiologic mechanisms of cerebral ischemia/infarction. The ischemic penumbra is an important concept and tissue region because this is the target of various recanalization treatments during the acute phase of stroke. In this context, it is high time for a thorough review of the concept, especially from the imaging point of view.
