1.  Posterior Lumbar Interbody Fusion Using Compressive Bone Graft with Allograft and Autograft in the Pyogenic Discitis 
Asian Spine Journal  2012;6(1):15-21.
Study Design
This is a retrospective study.
Purpose
To evaluate the advantages and effects of posterior lumbar interbody fusion (PLIF) using allograft and posterior instrumentation in the lumbar pyogenic discitis, which are resistant to antibiotics.
Overview of Literature
To present preliminary results of PLIF using a compressive bone graft with allograft and pedicle screw fixation in the lumbar pyogenic discitis.
Methods
Fifteen patients who had lumbar pyogenic discitis were treated by posterior approach from May 2004 to July 2008. The mean follow-up duration was 27.2 ± 18.68 months. The standing radiographs of the lumbar spine and clinical results were compared and analyzed in order to assess the bony union, the changes in the distance between the two vertebral bodies and the changes in the lordotic angle formed between the fused bodies immediately after surgery and at the final follow-up.
Results
Fifteen solid unions at an average of 15.2 ± 3.5 weeks after operation. The mean preoperative lordotic angle of the affected segments was 14.3 ± 15.1°, compared to 20.3 ± 12.3° after surgery and 19.8 ± 15.2° at last follow-up. For the functional result according to the Kirkaldy-Willis criteria, the outcome was excellent in 9, good in 5, fair in 1, and there were no poor cases. The average visual analogue scale score was decreased from 7.4 before surgery to 3.4 at 2 weeks postoperative.
Conclusions
The main advantage in the procedure of PLIF using compressive bone graft with allograft and post instrumentation is early ambulation. We believe that this is another good procedure for patients with poor general condition because a further autograft bone harvest is not required.

2.  Atypical Anterior Spinal Artery Infarction due to Left Vertebral Artery Occlusion Presenting with Bilateral Hand Weakness 
Background
Infarct of the anterior spinal artery is the most common subtype of spinal cord infarct, and is characterized by bilateral motor deficits with spinothalamic sensory deficits. We experienced a case with atypical anterior-spinal-artery infarct that presented with bilateral hand weakness but without sensory deficits.
Case Report
A 29-year-old man presented with sudden neck pain and bilateral weakness of the hands. Magnetic resonance imaging (MRI) of the brain did not reveal any lesion. His motor symptoms improved rapidly except for mild weakness in his left wrist and fingers. Magnetic resonance angiography showed proximal occlusion of the left vertebral artery; a spine MRI revealed left cervical cord infarction.
Conclusions
Bilateral or unilateral hand weakness can be the sole symptom of a cervical cord infarct.

3.  Long-term prognosis of symptomatic isolated middle cerebral artery disease in Korean stroke patients 
BMC Neurology  2011;11:138.
Background
This study aimed to investigate the long-term mortality and recurrence rate of stroke in first-time stroke patients with symptomatic isolated middle cerebral artery disease (MCAD) under medical management.
Methods
We identified 141 first ever stroke patients (mean age, 64.4 ± 12.5 years; 53% male) with symptomatic isolated MCAD. MCAD was defined as significant stenosis of more than 50% or occlusion of the MCA as revealed by MR angiography. The median follow-up was 27.7 months. We determined a cumulative rate of stroke recurrence and mortality by Kaplan-Meier survival analyses and sought predictors using the Cox proportional hazard model.
Results
The cumulative composite outcome rate (stroke recurrence or any-cause death) was 14%, 19%, 22%, and 28% at years 1, 2, 3, and 5, respectively. The annual recurrence rate of stroke was 4.1%. The presence of diabetes mellitus was the only significant independent predictor of stroke recurrence or any cause of death in multivariate analyses of Cox proportional hazard model adjusted for any plausible potential confounding factors.
Conclusions
We estimated the long-term prognosis of stroke patients with isolated symptomatic MCAD under current medical management in Korea. Diabetes mellitus was found to be a significant predictor for stroke recurrence and mortality.

4.  Hand Replantation with Proximal Row Carpectomy 
Hand (New York, N.Y.)  2008;4(1):55-61.
The purpose of this study is to present our operative technique and postoperative results of the hand replantation with proximal row carpectomy in cases of complete amputation at the level of wrist joint. From May 2003 to April 2005, five patients suffered from complete amputation of the hand due to industrial trauma. Amputation level was radiocarpal joint in three cases and midcarpal joint in two cases. Three cases represented guillotine type and two cases with local crush type injuries. All were men and the mean age was 26.6 years. The mean follow-up period was 26.8 months. At the time of replantation, the wrist joint was stabilized with transarticular fixation using three to four Kirschner’s wires after performing proximal row carpectomy. Postoperatively, functional results such as muscle strength, range of motion of the wrist and fingers, and sensory recovery were assessed according to Chen’s criteria. Joint width and arthritic changes of the radio-capitate joint were evaluated with radiologic tools. According to Chen’s criteria, the overall results in five cases were classified as grade II. Intrinsic muscle power of hands was found to be grade 4. The mean grip and pinch powers were 41% and 45%, respectively, compared to contralateral hand. The mean arc of flexion–extension of wrist was 53°. Total mean active motion of fingers was 215 degrees. Static two-point discrimination of fingertip ranged from 8 to 13 mm. On the follow-up, computerized tomography showed well-preserved radio-capitate joint space without any arthritic changes. While performing hand replantation after amputation at the radiocarpal or midcarpal level, proximal row carpectomy is a useful procedure to preserve joint motion of the wrist in selected cases.

5.  Experiences of pretreatment laparoscopic surgical staging in patients with locally advanced cervical cancer: results of a prospective study 
Journal of Gynecologic Oncology  2008;19(2):123-128.
Objective
To prospectively evaluate the feasibility, safety, and survival of laparoscopic surgical staging in patients with locally advanced cervical cancer.
Methods
From Oct 2001 to Jul 2006, a total of 83 consecutive patients were eligible for inclusion and underwent laparoscopic surgical staging.
Results
Three patients with intraoperative great vessel injury and 1 patient in whom the colpotomizer was unable to be inserted were excluded. Laparoscopic surgical staging was feasible in 95.2% (79/83). Immediate postoperative complications were noted in 12 (15.2%) patients. Prolonged complications directly related to operative procedures numbered 2 (2.5%), and were trocar site metastases. The mean time from surgery to the start of radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) was 11 (5-35) days. All patients tolerated the treatment well and completed scheduled RT or CCRT without disruption of treatment and additional admission. The rate of modification of the radiation field after surgical staging was 8.9% (7/79). Five-year progression-free survival and overall survival (OS) rates were 79% and 89%, respectively. The OS of patients with microscopic lymph node metastases, which were fully resected, were comparable to those of patients without lymph node metastasis. However, the OS of patients with macroscopic lymph node metastases that were fully resected were poorer compared with those of patients without lymph node metastasis.
Conclusion
Pretreatment laparoscopic surgical staging is a feasible and safe treatment modality. However the survival benefit of debulking lymph nodes or full lymph node dissection is not clear.

6.  Novel transglutaminase inhibitors reverse the inflammation of allergic conjunctivitis 
Journal of Clinical Investigation  2003;111(1):121-128.
Steroidal anti-inflammatory drugs induce proteins that inhibit phospholipase A2 (PLA2), including uteroglobin and lipocortin-1 (annexin I). Uteroglobin and lipocortin-1 retain several conserved sequences. Based on these sequences, several nonapeptides (antiflammins) were synthesized. These nonapeptides were shown to have anti-inflammatory effects in vitro and in vivo, possibly by inhibiting PLA2. Subsequent research showed that PLA2 is activated by transglutaminase 2 (TGase 2). We hypothesize here that TGase 2 inhibitors may increase the anti-inflammatory efficacy of inhibiting PLA2 activity. To test this theory, we constructed recombinant peptides containing sequences from pro-elafin (for inhibition of TGase 2), and from lipocortin-1, lipocortin-5, and uteroglobin (for inhibition of PLA2). The recombinant peptides, which had dual inhibitory effects on purified TGase 2 and PLA2, reversed the inflammation of allergic conjunctivitis to ragweed in a guinea pig model. The present work suggests that novel recombinant peptides may be safe and effective agents for the treatment of various inflammatory diseases.
