OBJECTIVE: To explore the clinical value of postoperative follow-up examination of F-wave and H-reflex in patients with lumbosacral radiculopathy and to clarify optimal timing of follow-up examination. METHOD: The subjects were 17 patients with unilateral lumbosacral radiculopathy caused by disc herniation. In patients with the L5 radiculopathy, F-waves were obtained from extensor digitorum brevis and six parameters including minimal latency per height were used. In patients with the S1 radiculopathy, H-reflexes were obtained from gastrocnemius and amplitude and minimal latency were used as parameters. These parameters were evaluated preoperatively and postoperatively at week 1, 3, 6. These changes of the parameters and clinical findings were related. RESULTS: The parameters of peroneal F-wave and tibial H-reflex showed significant improvement at 3 weeks and 6 weeks after surgery. The improvements of these parameters were not related with clinical improvement at 1 week after operation, but these were significantly related with improvement of pain and muscle weakness at 3 weeks after operation. CONCLUSION: These findings suggested that follow-up examination of F-wave and H-reflex were valuable for objective assessment of lumbosacral radiculopathy after operation and the optimal timing for follow-up study was 3 weeks after operation.

A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

Ligament and tendon prostheses have all suffered because of failure of the particular material that has used in the past. Various materials, including, silk, nylon, Dacron, and combinstions of other synthetic substances, have all enjoyed temporary vogues and have vogues and have all passed out of habitual use because of collapse of the material employed. In an attempt to find an alternative material for use as a tendon or ligament prosthesis, a fundamentally new approach to the problem has been used, namely, that of tendon ligament induction. Carbon fiber has an attraction as a biologic implant because of its inherently inert nature when used in the pure form. Within recent years, it has been possible to manufacture filamentous carbon fiber of high purity and constant filament size, and this material has been examined as a tendon and ligament prosthesis. Both achilles tendons of 14 adult Korean rabbits were replsced with carbon fiber reinforced epoxies(CFRE, it was developed in department of chemical engineering, Chungnam national university, Daejeon, Korea) after artificially rupture, and serial histologic examination of neotendon formations and biologic responces in vivo were done during 8 weeks. The results obtained were as followings ;1. Hemorrhage and inflammatory reactions were observed at 2–3 weeks after operations. 2. Foreign body reactions were developed at 4 weeks after operation, also observed proliferations of foreign body giant cells and histiocytes. 3. Fibroblasts were increased at 4 weeks after operation, and most severe poliferations at 5–6 weeks. 4. Foreign body reactions and fibroblasts were markedly decreased at 7–8 weeks after operation, and examination of the collagen itself showed it to be closely similar to that found on the normsl side.5. Thus, it appeared that the carbon fiber initially acted as a tendon prosthesis.

PURPOSE: Peripheral neuropathy is common among colorectal cancer (CRC) patients who undergo oxaliplatin-based (OXL) chemotherapy. A pharmacogenetic approach can be used to identify patients at high-risk of developing severe neuropathy. This type of approach can also help clinicians determine the best treatment option and prevent severe neurotoxicity. The purpose of this study is to investigate the evidence of pharmacogenetic markers for OXL-induced peripheral neuropathy (OXIPN) in patients with CRC. METHODS: A systematic literature search was conducted using the following databases up to December 2017: Pubmed, EMBASE, and CINAHL. We reviewed the genetic risk factors for OXIPN in observational studies and randomized controlled clinical trials (RCTs). All processes were performed independently by two reviewers. RESULTS: Sixteen studies published in English between 2006 and 2017 were included in this review. A genome-wide association approach was used in one study and various candidate genes were tested, based on their functions (e.g., DNA damage or repair, ion channels, anti-oxidants, and nerve growth etc.). The genes associated with incidence or severity of OXIPN were ABCG2, GSTP1, XRCC1, TAC1, and ERCC1. CONCLUSION: This study highlighted the need and the importance of conducting pharmacogenetic studies to generate evidence of personalized OXIPN symptoms management. Additional studies are warranted to accelerate the tailored interventions used for OXIPN in patients with CRC (NRF-2014R1A1A3054386).

2 patients of forearm deformities with ulnar defect and radial head dislocation were treated with the Ilizarov apparatus at Chungnam University Hospital. One patient had a severe hypoplastic remnant-like ulnar fragment and a anterolaterally dislocated radial head due to complicated osteomyelitis of ulnar. We applied an Ilizarov apparatus to transport the radial head distally, and fixed to remaining proximal ulnar fragment. The other had a large bony defect at the ulnar shaft and a dislocated radial head due to complicated osteomyelitis of ulna. We performed internal transport of ulna to decreased the ulnar defect and to descend the dislocated radial head. The clinical-radiological features and functional results of those 2 forearm deformities were described with brief review of the articles about the Ilizarov method for correction of forearm defor- mities.

Cubitus varus deformity is the late complication of the supracondylar fracture of humerus which is common in growing children. If the deformity is severe it causes tunctional problems as well as cosmetic ones necessitating conective osteotomy. Though many authors devised different methods of corrective osteotomy, the cosmetic results are not always satisfactory because of the development of the lazy S deformity hy the lateral prominence. Technically. the initial stahility of the osteotomy is also poor due to the poor contact of the osteotomy site. So we have devised a new quadrilateral displacement osteotomy to increase the initial stability of the osteotomy by creating a wedge on the osteotomy site & also to prevent the development of the lazy S deformity hy elimination of the Interal prominence. We treated 9 cases of cubitus varus deformity with the new quadrilateral displacement osteotomy. The correction technique was not difficult & the initial stahility of the osteotomy is rather good & the osteotomy is fixed by the conventional methods, & all of the cases were healed uneventfully. There developed no the lazy & deformity after osteotomy. We would like to report the details ot the supracondylnrquadrilateral displacemenl osteotomy.
