Diastematomyelia, a form of spinal dysraphism, is characterized by a division of the spinal cord or canda equina resulting the form a bony or cartilaginous spur which transfixes the neural elements and dura. The presence of a structure of neural crest origin in the subarachnoid space connecting the spicules suggested that the anomaly resulted from delayed closure of the neural tube and its investments. The cinical finding are presumed due to its restriction, tethering of the normal apward migration of the spinal cord. Congenital anomalies of one or both lower extremities and spine are frequently found with this condition. The surgical removal is recommended as a prophylactic measure against further progressive neurological damage. The purpose of this paper is to presented becanse it was associated with clubfoot and adds to understanding of teratogenesis of diastematomyelia.

Authors presented the gratifying result of treatment of chronic osteomyelitis with overlying skin defect and/or poor skin condition, which developed the wide skin necrosis after saucerization and resulted the second skin graft necessary. Five cases were treated by primary extensive saucerization of tibia which left a cavity with bleeding walls. The exposed bony surface with bleeding walls was covered by delayed free skin graft when the good granulation covered the bony surface. Through this experience, delayed free skin graft is justified the best procedure in these cases to cover the post-surgical raw bone surface and to have primary healing of the bone infection. A method of hemicylindrical pedunculated skin graft to obliterate the deeply excavated surgical bony defect is introduced.

The principal cause of avulsion fracture of anterior superior iliac spine is sudden powerful contraction of sartorius muscle in strenuous sporting activities. The condition usually occurs in young people in whom the apophysis has still not firmly united to the ilium. We presented the three cases of avulsion fracture of anterior superior iliac spine which occurred during sprinting in Physical Fitness Test.

The pinching motion is thought to be one of fundamental hand functions, the power of which has been quantified by measuring it isometrically with variously devised pinch-meters. The present authors describe the investigations on the pinching power of 350 healthy persons, 200 male and 150 female Koreans, by the use of Preston Pinch Gauge. Six kinds of pinch were chosen: (1) thumb index finger tip pinch (1-2TP), (2) thumb-middle finger tip pinch (1-3TP), (3) thumb-index finger pulp pinch (1-2PP), (4) thumb-middle finger pulp pinch (1-3PP), (5) thumb-index-middle finger pulp pinch (3PP), (6) key pinch (KP), which were classified again into 19 kinds according to the shape of thumb, index, middle, or other fingers during each pinch. We describe those as principal type, hyperextension-flexion type, hyperextension type and other type into four. It should be justified to calculate the mean normal value of principal type pinching power in Korean. Principal type of pinch involves 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP, as to Hyperextension type of 1-2PP, 1-3PP, 3PP and KP. Other type of pinch involving 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP is different from Principal type simply because of the shape of nonjoining fingers during pinch. Generally, the pinching power of Principal type was clearly highest among the four types except for pulp pinches.

BACKGROUND/AIMS: The emergence of lamivudine-resistant mutant hepatitis B virus (HBV), with aminoacid substitution in the YMDD motif of DNA polymerase, has been reported in the long-term lamivudine use group. However there is no report about the emergence of mutant viruses during the short-term lamivudine therapy. The objective of this study was to investigate the emergence of YMDD mutant HBV during short-term lamivudine therapy. METHODS: We evaluated twenty-eight chronic hepatitis B patients who were HBeAg and HBV DNA positive and treated with lamivudine 100mg p.o. daily for 12 weeks. First, we investigated the emergence of YMDD mutants by nested polymerase chain reaction (PCR) method developed by Chayama et al in 19 patients who lost HBV DNA during lamivudine therapy but showed HBV DNA re-emergence 2 weeks after the end of therapy. Second, DNA subcloning and sequencing of HBV DNA polymerase including YMDD motif was undertaken in one patient's serial blood samples at 0, 8, 12 weeks to confirm the results of nested PCR. RESULTS: YMDD motif mutation was detected in 17(90%) out of 19 patients at the end of therapy and the type of mutations were YIDD only. At the end of therapy, mutant was predominant in 5 patients, both mutant and wild type were similar in proportion in 3 patients, and wild type was predominant in 9 patients. When we carried out nested PCR serially with samples of 0, 2, 4, 8, 12, 14 weeks after initiation of therapy in 5 patients who were mutant predominant at 12 weeks, YIDD mutant began to be detected from 2 weeks in 4 patients and from 4 weeks in one patient. However, rapid turnover from mutant to wild type happened after the end of therapy, so only wild type was detected in 3 patients and wild type became predominant in 2 patients at 2 weeks after the end of therapy. All the sequencing results of serial blood samples in one patient were consistent with nested PCR data. CONCLUSIONS: The presence of YMDD motif HBV polymerase mutant may be possible before administration of lamivudine in Korean chronic hepatitis B patients. Nested PCR assay would be an useful method to detect YMDD mutant.

Since 1985, authors have applied a cast ring around the reconstructed pully involving adjacent one normal digit and allowed early dynamic motion after one stage tenolysis or tendon graft in 24 digits of 16 patients with old flexor tendon injuries in zone II. With this ring technique, authors obtained satisfactory results in 80% of the patients, which proved to be as good as two stage flexor tendon reconstruction with silicone rodding. A cast ring allowed early active motion after tenolysis and early dynamic passive motion after tendon graft. It served as temporary external augmentation of the reconstructed pully and seemed to reduce the tension at the reconstruced tendon and pully. One stage flexor tendon reconstruction and early dynamic motion with ring technique was advantageous in shortening of morbidity and postoperative rehabilitation period, and eliminating complications from silicone rodding.

PURPOSE: To describe the MR features of intraspinal cysticercosis. MATERIALS AND METHODS: Medical records and MR images of four cases of intraspinal cysticercosis were retrospectively reviewed. The MR findings were described with regard to the location and signal intensity of the lesions, contrast enhancement, presence or absence of associated intracranial cysticerci, and other findings. RESULTS: There were three cases of subarachnoidal form and one case of intramedullary form. Cysticerci of subarachnoidal form in three cases were located in retromedullary space at C2 level, anterior to cord at C1 -C6 levels, and lumbosacral area, respectively. The signal intensities of the lesions were same as those of CSF. Localized arachnoidal enhancement was found in all three cases. In one case there was a large area of high signal intensity within the spinal cord on T2 weighted image suggesting either ischemia secondary to vascular compromise or inflammatory edema. All of these three cases accompanied intracranial cysticercosis. Intramedullary cysticercosis in one case was shown as a single I cm cystic lesion at C2 level, which showed hypointense signal on T1 weighted image, hyperintense signal on T2-weighted image, and signet-ring-like enhancement. This lesion did not accompany intracranial cysticerci. CONCLUSION: lntraspinal cysticercosis manifested as single or multiple cysts within either spinal cord or subarachnoid space, and were frequently associated with arachnoiditis.
