3.The comparison of survival of the venous flaps according to the location of pedicle and the treatment of superoxide dismutase in the rabbit auricle.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(4):538-546
It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.

We presented a case of Reiters syndrome consisting of conjunctivitis, arthritis, and skin lesions, occurring in 20-year-o1d male. He had neither an episode of dysentery nor a history of sexual exposure before onset of syndrome. The skin lesions had begun with erythernatous scaly patches on the inguinal region and scalp, and later followed by generalized pustular, psoriasiform and/or hyperkeratotic crusted lesions on the erythematous base. Yellowish discoloration and onycholysis of nails and shallow ulcer of glans penis were observed. Arthritis of the knee and shoulder joints were developed, accompanied by pain, swelling, limited motion, wasting and weakness of both lower extremities. In laboratory investigation, urinalysis, stool examination for parasites and occult blood, renal function test, blood VDRL, and X-ray of chest, both knee. joints, shoulder joint and thoracolumbar spine were within normal limit or negative except for leukocytosis(24, 500/mm), increased ESR(90 mm/hr) and hypoalbuminemia(2.6 g/dl), and he was associated with HLA-A3, A 9, B5, and Rw 49 Histopathologically skin biopsy specimen showed extensive hyperkeratosis, paralceratosis, elongated rete ridges, spongiform macropustule of Kogoj. He was treated effectively with antibiotics, corticosteroid, and methotrexate for two months without recurrence till now.

We report a 71 years old woman with transient periodic limb movement disorder and myoclonus that
appeared after acute gastrointestinal bleeding. The abnormal movements dissolved as the blood loss
was restored. The woman was later found to have an asymptomatic spine meningioma. Iron defi ciency
due to acute bleeding may be the trigger resulting in the abnormal movements in this patient with
subclinical spinal meningioma

A 23-year-old man had multiple small, skin-colored firm papules on the both sides of the nasolabial folds since the age of approximately 17. His mother had a similar skin lesions on her face. The histopathological findings of skin biopsy specimens from patient(son) showed horn cysts consist of a fully keratinized center surrounded by basophilic cells and tumor islands composed of basophilic cells arranged in a lacelike or adenoid network and occasional solid aggregates and there are also a foreign body giant cell reaction in the vicinity of the ruptured horn cysts.

STUDY DESIGN: Lumbar disc degeneration and segmental instability of the lumbar spine are causes of low back pain. Disc degeneration causes specific changes of the intervertebral disc, and could affect anatomic variations of end plate and vetebral body. However, the exact relationship between degenerative changes of the intervertebral disc and segmental motion characteristics is not known. It is known that radial tears of the annulus fibrosus initiate or accompany degenerative process of nucleus pulposus and the motion segment. It is hypothesis of this study that the existence of radial tear in the annulus fibrosis affects 3 dimension motion characteristics of motion segment. For the purpose, the degree of intervertebral disc degeneration is newly classified by existence of radial tear. Then, the resulting biomechanical motions are investigated. OBJECTIVES: To investigate effects of disc degeneration by the classification on kinematic motions of the motion segment from human lumbar spine and to suggest a quantified method to determine spinal instability in vivo. MATERIALS AND METHODS: A total of 60 spinal motion segments from human lumbar spine was used for this study. To measure 3 dimensioal motion of the motion segments, Vicon system(Oxford, England) with 3 cameras reflective markers and VAX station was used. 6 kinds of pure moments(flexion, extension, right and left axial rotation, and right and left lateral bending) were applied to the motion segments using dead weight for each loading step. At the end of test(maximum loading), motion segments were frozen for anatomical study. For making clear the degree of the degeneration of the disc, a new classification based on MRI results was used: Grade 1 is a normal young disc without tear; Grade 2 is a normal aging disc without radial tear; Grade 3 is a degenerative disc with radial tear; and Grade 4 is a severely degenerative disc with radial tear and other degeneration such as showing decreased disc height. RESULTS: The upper lumbar specimens with radial tears has increased flexion motions as compared to the normal group. Also, the right and left axial rotation in radial tear group increased as compared to the normal group. However, there were no statistical differences in other motions. For the lower lumbar specimens, there were no significant differences in measured motions in all directions between the normal and radial tear groups CONCLUSIONS: These results suggests that the segmental motions are affected by radial tear in the intervertebral disc. Thus, the radial tear in the annulus fibrosus of lumbar intervertebral disc could cause the instability of lumbar spine. Further research is required to determine the relationship between other structural changes and biomechanical characteristics, and future studies should include in vivo investigations to correlate these findings to patients'symptoms.

The authors experienced a case of secondary glaucoma combined with mesodermal dysgenesis of anterior segment, which disclosed extensive peripheral iridocorneal adhesion of congenital origin while his fellow eye revealed a sclerocornea. This case is extremely rare and entirely different from the previously reported Axenfeld's and Rieger's anomalies. We report this interesting case with brief review of the literatures.

Kaposis sarcoma(KS) is a multicentrically developing vascular neoplasm with four types of clinical manifestation. One of these, classic KS is clinically carmcterized by late onset, chronic course and radiosensitive. We report a case of classic KS in a 72-year-old male. This pateint complainted of purple patches and dark purple nxluk. on slightly edematous lower legs. The histopathologic sections from the lesional sites showed infiltration of spindle cells with newly formed vascular slits, dilated blood vessels and aggregated hemosiderins in the dermis.
