A case of Coats' disease in 15 years old boy was presented with some clinical observation. This is a rare unilateral retinal disorder with hemorrhagic and exudative properties affecting otherwise healthy young boys. A brief review of literatures has also been described.

OBJECTIVE: We analyzed the clinical and radiologic features of posterior apophyseal ring separation (PARS) with lumbar disc herniation and suggest the proper management options according to the PARS characteristics. METHODS: We reviewed case series of patients with PARS who underwent surgery of lumbar disc herniation. Preoperative symptoms, neurologic status, Body Mass Index, preoperative and postoperative Visual Analogue Scale (VAS) and Korean-Oswestry Disability Index (K-ODI) scores, operation types were obtained. PARS size, locations, the degree of resection were assessed. RESULTS: PARS was diagnosed in 109 (7.5%) patients among 1448 patients given surgical treatment for single level lumbar disc herniation. There were 55 (50.5%) small PARS and 54 (49.5%) large PARS. Among the large PARS group, 15 (27.8%) had lower endplate PARS of upper vertebra at the level of disc herniation. Thirty-nine (72.2%) were upper endplate PARS of lower vertebra. Among the group with upper endplate PARS of lower vertebra, unresected PARS was diagnosed in 12 (30.8%) cases and resected PARS was diagnosed in 27 (69.2%) cases. VAS and K-ODI scores changes were 3.6+/-2.9 and 5.4+/-6.4 in the unresected PARS group, 5.8+/-2.1 and 11.3+/-7.1 in the resected PARS group. The group with upper endplate PARS of lower vertebra showed significant difference of VAS (p=0.01) and K-ODI (p=0.013) score changes between unresected and resected PARS groups. CONCLUSION: The large PARS of upper endplate in lower vertebra should be removed during the surgery of lumbar disc herniation. High level or bilateral side of PARS should be widely decompressed and arthrodesis procedures are necessary if there is a possibility of secondary instability.

OBJECTIVES: The goal of operation for degenerative lumbar diseases is to relieve radiculopathy and low back pain and to prevent further degeneration. The authors analyzed the surgical results of posterior lumbar interbody fusion(PLIF) and 360degrees fixation to evaluate the proper treatment policy in spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. MATERIAL AND METHODS: The authors performed PLIF on 92 patients and 360degrees fixation on 138 patients with spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. We retrospectively studied clinical outcomes and subjective satisfaction of these patients by several criteria such as visual analog scale(VAS), Prolo's economic and functional outcome scale, medication usage after operation and questionaire for overall outcome. RESULT: Pre- and postoperative VAS on back pain and leg pain showed decrease of pain from 6.5, 6.7 to 2.2, 2.4 in PLIF group and from 7.0, 7.2 to 2.5, 2.7 in 360degrees fixation group. Excellent and good outcomes on Prolo's scale were 81.5% in PLIF group and 82.6% in 360degrees fixation group. Medication usage after operation was reduced in 79.3% of PLIF group and in 78.3% of 360degrees fixation group. Patients' self-reported overall success of their procedure showed 82% in PLIF group and 84% in 360degrees fixation group. CONCLUSION: Both PLIF and 360degrees fixation showed good outcomes and provided biomechanically stable fusion in spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. Therefore, only PLIF seems necessary and considered a proper surgical treatment for these disorders.
