OBJECTIVE: Recurrent herniation following disc excision has been reported in 5-15% of patients. There have been numerous studies of recurrent disc herniation, but these have analyzed mixed patient populations. We designed this study to analyze the factors that influencing the clinical results, and efficiency of repeat discectomy for recurrent lumbar disc herniation occurring at the same level and on the same side after primary discectomy. METHODS: Between 1990 and 2011, a total of 52 patients who underwent repeat discectomy for recurrent lumbar disc herniation were retrospectively analyzed. Clinical outcomes were measured with Macnab criteria and visual analog scale (VAS score). Clinical parameters were also analyzed for influencing factors for outcome. RESULTS: Based on Macnab criteria, an excellent surgical outcome was achieved in 28 cases (54%), a good outcome in 22 cases (42%), a fair outcome in 1 case (2%), and a poor outcome in 1 case (2%). Based on VAS score, 47 of 52 patients (90%) showed more than 4 score improvement. Age, sex, diabetes mellitus, smoking, time interval between repeat and primary discectomy, duration of recurrent symptoms, and extent of disc herniation did not significantly affect Macnab criteria and VAS score. However, a traumatic event showed less VAS score improvement whereas not affecting on Macnab criteria. CONCLUSION: Conventional open lumbar discectomy performed as repeat surgery for recurrent herniation showed satisfactory results. Based on the results of this study, repeat discectomy can be recommended for the management of recurrent lumbar disc herniation. Further study is needed to evaluate factors related to the outcomes of repeat discectomy.

OBJECTIVE: Epidural fibrosis and adhesion are the main reasons for post-laminectomy sustained pain and functional disability. In this study, the authors investigate the effect of irradiated freeze-dried human amniotic membrane on reducing epidural adhesion after laminectomy on a rat model. METHODS: A total of 20 rats were divided into two groups. The group A did not receive human amniotic membrane implantation after laminectomy and group B underwent human amniotic membrane implantation after laminectomy. Gross and microscopic findings were evaluated and compared at postoperative 1, 3 and 8 weeks. RESULTS: The amount of scar tissue and tenacity were reduced grossly in group of rats with human amniotic membrane implantation (group B). On a microscopic evaluation, there were less inflammatory cell infiltration and fibroblast proliferation in group B. CONCLUSION: This experimental study shows that implantation of irradiated freeze-dried human amniotic membrane reduce epidural fibrosis and adhesion after spinal laminectomy in a rat model.

Recently with the development of magnetic resonance imaging(MRI) techniques, many reports of radiologic findings in spontaneous intracranial hypotension(SIH) have been reported. However in our review, the pachymeningeal changes within spinal canal secondary to SIH are not reported. In SIH, same mechanisms of it might act in the intraspinal space, which cause pachymeningeal changes of spinal dura and clinical features of spinal involvement. We reports four cases of SIH, in which MRI of the brain and spine reveals diffuse symmetric pachymeningeal enhancement. This is the first report of the spinal images in SIH.

Gummy stem blight is a major foliar disease of muskmelon (Cucumis melo L.). In this study, morphological characteristics and rDNA internal transcribed spacer (ITS) sequences were analyzed to identify the causal organism of this disease. Morphological examination of the Jeonbuk isolate revealed that the percentage of monoseptal conidia ranged from 0% to 10%, and the average length x width of the conidia was 70 (+/- 0.96) x 32.0 (+/- 0.15) microm on potato dextrose agar. The BLAST analysis showed nucleotide gaps of 1/494, 2/492, and 1/478 with identities of 485/492 (98%), 492/494 (99%), 491/494 (99%), and 476/478 (99%). The similarity in sequence identity between the rDNA ITS region of the Jeonbuk isolate and other Didymella bryoniae from BLAST searches of GenBank was 100% and was 95.0% within the group. Nucleotide sequences of the rDNA ITS region from pure culture ranged from 98.2% to 99.8%. Phylogenetic analysis with related species of D. bryoniae revealed that D. bryoniae is a monophyletic group distinguishable from other Didymella spp., including Ascochyta pinodes, Mycosphaerella pinodes, M. zeae-maydis, D. pinodes, D. applanata, D. exigua, D. rabiei, D. lentis, D. fabae, and D. vitalbina. Phylogenetic analysis, based on rDNA ITS sequence, clearly distinguished D. bryoniae and Didymella spp. from the 10 other species studied. This study identified the Jeonbuk isolate to be D. bryoniae.

Heterotopic pregnancy describes the rare coexistence of intrauterine and extrauterine gestations. The commonly accepted incidence is 1:30,000 but the actual number is significantly higher. This condition remains difficult to diagnose and potentially dangerous to both mot- her and fetus. The incidence has risen after wider use of ovulation induction and the adve- nt of techniques of assisted reproduction. We report a case of simultaneous intrauterine pregnancy and tubal pregnancy.

Bronchial Asthma could be developed by occupational origin. 4-16% of bronchial asthmas are known to be related to occupational exposure. However, occupational asthma has not been reported from the periodic occupational health examination, but reported through case report from clinicians. The authors analysed hospital records to find out work-related bronchial asthma and their occupational characteristics at a university hospital in Jnchon. All records which were confirmed as bronchial asthma in adult by an allergist from June, 1996 to May, 1998 were selected. Through record reviewing, any suspected work related asthma was selected and the interview was done by phone or at the out-patient clinic. The possible cases were confirmed by additional tests including specific bronchial provocation test. Sixteen(3. 9%) out of 411 bronchial asthma were confirmed as work-related asthma. Eight cases out of 16 worked at furniture industry, three worked at dye manufacturing and two worked at musical instrument manufacturing industry. Others worked at farm and machinary industry. The confirmed asthmogen were toluene diisocyante(8), reactive dye(3), and grain dust(1). None of the cases was detected as work-related asthma in the periodic health examination. Twelve out of sixteen occupational asthma patients discontinued their work. The results suggested that many patients with occupational asthma were not reported and the periodic health examination was not an effective system for detecting the workrelated asthma. Thus, setting up the surveillance system involving allergist or pulmonologist would be important to detect and prevent occupational asthma.

Agrocybe aegerita is an important mushroom cultivated in Korea, with good feel and a peculiar fragrance. A. aegerita can be cultivated throughout the year using culture bottles but is more susceptible to contamination than other mushrooms. Twenty-two pathogens were isolated from the fruiting bodies and compost of A. aegerita, and seven isolates were isolated from Pleurotus ostreatus to compare with the A. aegerita isolates, collected from Gimje, Iksan, Gunsan of Chonbuk, and Chilgok of Gyeongbuk Province in 2009. These isolates were identified based on morphological and molecular characteristics. Of the 29 isolates, 26 were identified as Trichoderma spp. and the remaining three were Aspergillus spp., Mucor spp., and Penicillium spp. A phylogenetic analysis revealed that the 26 isolates of Trichoderma were divided into four taxa, namely T. harzianum, T. pleuroticola, T. longibrachiatum, and T. atroviride. Among the Trichoderma spp., 16 isolates (55.2%) were identified as T. harzianum, six as T. pleuroticola (20.7%), two as T. longibrachiatum, and the remaining two were T. atroviride.

We studied on change of lens accommodation and pupil light reflex caused by VDT work in six women and compared them with those of other office works. The results were as follows. 1. In VDT work group, the accommodation contraction velocity decreased during the first 2-hr VDT task, then recovered markedly by the end of the one-hour lunch break, and then decreased again by the end of the 2nd 2-hr VDT task. Changes of relaxation velocity showed similar pattern although it was less typical than that of contraction velocity. 2. There was no marked change in accommodation contraction velocity and amplitude of accommodation in general office work group and near-distance office work group, and in the near-distance office work accommodation relaxation velocity decreased according to work load without recovery after lunch break. 3. Initial pupil diameter, initial pupil area of light reflex decreased significantly during VDT task only in VDT work group, and didn't recover after lunch break. These results suggest possibility that changes of accommodation contraction velocity, accommodation relaxation velocity, near point distance, and pupil diameter and area are useful in evaluating characteristics of VDT work. For this, more research adjusted individual differences, circadian rhythm, emotional stress needs.
