OBJECTIVE: To evaluate the beneficial effect of botulinum toxin A (Botox) injection into the subscapularis muscle on intractable hemiplegic shoulder pain. METHODS: Six stroke patients with intractable hemiplegic shoulder pain were included. Botulinum toxin A was injected into the subscapularis muscle. Intractable hemiplegic shoulder pain was evaluated using an 11-point numerical rating scale. Pain-free range of motion was assessed for shoulder abduction and external rotation. The spasticity of the shoulder internal rotator was measured using the modified Ashworth scale. Assessments were carried out at baseline and at 1, 2, 4, and, if possible, 8 weeks. RESULTS: Intractable hemiplegic shoulder pain was improved (p=0.004) after botulinum toxin injection into the subscapularis muscle. Restricted shoulder abduction (p=0.003), external rotation (p=0.005), and spasticity of the shoulder internal rotator (p=0.005) were also improved. Improved hemiplegic shoulder pain was correlated with improved shoulder abduction (r=–1.0, p<0.001), external rotation (r=–1.0, p<0.001), and spasticity of the internal rotator (r=1.0, p<0.001). CONCLUSION: Botulinum toxin A injection into the subscapularis muscle appears to be valuable in the management of intractable hemiplegic shoulder pain.

BACKGROUND: There were no effective methods to monitor the treatment of leprosy. Anti-PGL-1 ELISA test and polymerase chain reaction(PCR) were used for monitoring the treatment, however many restrictions have been found to apply to those methods in the field. Bacillary index(BI) is a popular and not an expensive method. For this reason, the exact data to assess the efficacy of the standard multi-drug therapy(MDT) with BI is required for evaluation of the treatment in Korea. OBJECTIVE: The purpose of this study was to clarify the change of bacillary index during MDT in multi-bacillary leprosy(MB) cases. METHODS: A total of 72 patients in the National Sorokdo Hospital were included in this study. With the retrospective method, BI, type of leprosy, relapse, age, and duration of treatment were evaluated. RESULTS: The results were as follows; 1.In this study, the mean duration of BI changing from 6 to 5 was 5.7 months, from 5 to 4 was 6.6 months, from 4 to 3 was 13.1 months, from 3 to 2 was 13.8 months, from 2 to 1 was 12.4 months, from 1 to 0 was 29.4 months. 2.The time of initial change of BI after MDT were as follows: within 3 months(26.4%), 4-6 months(29.2%), 7-12 months(26.4%), 13-18 months(8.3%), 19-24 months(4.2%), 25-48 months(5.5%). The mean duration was 8.9 months. 3.The mean cumulative time of BI to 0 was 68.4 months CONCLUSION: These results suggest that after MDT, in most of MB, BI decreased within one year and it took 68.4 months for BI to be 0. At first, BI decreased relatively fast, however a longer period was required to become a state of BI 0.

BACKGROUND AND OBJECTIVES: QT dispersion (QTd) is defined as the difference between the maximum and minimum QT interval in any of the 12 leads of the surface ECG. QTd has been shown to reflect regional variations in ventricular repolarization. Ischemic dilated cardiomyopathy (DCM) may lead to more spatial and temporal dispersion in ventricular repolarization than idiopathic DCM. The purpose of this study was to determine the difference of QTd between patients who had ischemic and idiopathic DCM. MATERIALS AND METHODS: The study population included 30 patients with ischemic DCM and 30 with idiopathic DCM. All standard 12-lead ECGs were examined prospectively by two observers who were unware of the patient's details. RESULTS: QTd in ischemic DCM was significantly higher than that in idiopathic DCM (63+/-32 vs. 44+/-26 msec, p=0.012) and JTd in ischemic DCM was significantly higher than that in idiopathic DCM (48+/-21 vs. 36+/-22 msec, p=0.036). Results did not change when Bazett's QTc and JTc was substituted for QT (QTcd:69+/-33 vs. 52+/-28 p=0.039) and JT (JTcd:56+/-21 vs. 41+/-25 p=0.043). CONCLUSION: Ischemic DCM has increased spatial inhomogeneity of repolarization probably due to more regional myocardial damages compared with idiopathic DCM. The value of QT dispersion as an easily accessible, non-invasive method in predicting the risk of life threatening arrhythmia and overall mortality in patients with dilated cardiomyopathy must be confirmed in prospective trials.

PURPOSE: This study was designed to analyze the short-term clinical and functional outcomes of perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. METHODS: The data were prospectively collected and consisted of the clinical data, the functional status before and after surgery, the operation record, and the postoperative course. The functional status was evaluated by using Wexner's constipation score (0-30), Wexner's incontinence score (0-20), anorectal manometry, and pudendal nerve terminal motor latency. Follow-up was performed at 3-6 months after the operation by using both a standardized questionnaire completed in the outpatient clinic or telephone interview (n=23) and an anorectal physiology test (n=7). RESULTS: During a one-year period, 23 patients (male=10) underwent perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. The median duration of the operations was 88 minutes. The median length of postoperative hospital stay was 6 days. There was one urinary tract infection and no mortalities. The constipation score was significantly decreased after the operation (9.8 vs 3.8; P<0.001), and constipation was improved in 90 percent (19/21) of the cases. The incontinence score was significantly decreased after surgery (mean preop.=11.6, postop.=3.7; P<0.001) and incontinence was improved in 17 of 21 patients with impaired continence (81 percent). Anal sphincter function was not improved but rectal reservoir capacity was significantly decreased after surgery (rectal urgent volume (45.7 cc vs 37.1 cc; P=0.045), maximal tolerable volume (120 cc vs 85.7; P=0.011). Most patients (83 percent) felt that the operation had improved their symptoms. The major reasons for dissatisfaction after surgery were frequent defecation, fecal soiling, persistent or aggravated fecal incontinence, and recurrence. One patient had a complete recurrence (4.3 percent), and another patient had a mucosal prolapse which was treated. CONCLUSIONS: Perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse is a safe technique with acceptable short-term functional results; however, it is not recommended for rectal prolapse patients with diarrhea-predominant irritable bowel syndrome.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of spinal implant removal and to determine the possible mechanisms of pain relief. METHODS: Fourteen patients with an average of 42 years (from 22 to 67 years) were retrospectively evaluated. All patients had posterior spinal instrumentation and fusion, who later developed recurrent back pain or persistent back pain despite a solid fusion mass. Patients' clinical charts, operative notes, and preoperative x-rays were evaluated. Relief of pain was evaluated by the Visual Analog Scale (VAS) pain change after implant removal. Clinical outcome using VAS and modified MacNab's criteria was assessed on before implant removal, 1 month after implant removal and at the last clinical follow-up. Radiological analysis of sagittal alignment was also assessed. RESULTS: Average follow-up period was 18 months (from 12 to 25 months). There were 4 patients who had persistent back pain at the surgical site and 10 patients who had recurrent back pain. The median time after the first fusion operation and the recurrence of pain was 6.5 months (from 3 to 13 months). All patients except one had palpation pain at operative site. The mean blood loss was less than 100ml and there were no major complications. The mean pain score before screw removal and at final follow up was 6.4 and 2.9, respectively (p<0.005). Thirteen of the 14 patients were graded as excellent and good according to modified MacNab's criteria. Overall 5.9 degrees of sagittal correction loss was observed at final follow up, but was not statistically significant. CONCLUSION: For the patients with persistent or recurrent back pain after spinal instrumentation, removal of the spinal implant may be safe and an efficient procedure for carefully selected patients who have palpation pain and are unresponsive to conservative treatment.

BACKGROUND: The pathogenesis of silicosis has been focused on the interaction between alveolar macrophages and silica particle. Although fibrosis in silicosis has been studied extensively, the mechanism is still not fully understood. There is increasing evidence that monokines and arachidonic acid metabolites produced by macrophage are involved in pathogenesis of silicosis. Recently, it was reported that prostaglandin E2 produced from macrophage counteracts the stimulatory effects of other monokines on fibroblast proliferation or collagen production. Until now, it was remained uncertain by which mechanism silica particle may activate alveolar macrophage to an enhanced release of prostaglandin E2. METHODS: In order to investigate the relationship between the activity of alveolar macrophage and the production of PGE2 from activated alveolar macrophage, the authors measured hydrogen peroxide and PGE2 from alveolar macrophages activated by silica in vitro and from alveolar macrophages in the silicotic nodules from rat. Experimental silicosis was induced by intratracheal infusion of silica(SiO2) suspended in saline (50 mg/ml) in Sprague-Dawley rats. RESULTS: 1) The silicotic nodules with fibrosis were seen from the sections of rat lung at 60 days after intratracheal injection with 50 mg aqueous suspension of silica. 2) In vitro, silica caused the dose dependent increase of hydrogen peroxide(p<0.05) and PGE2(p>0.05) release from alveolar macrophages. Alveolar macrophages from rats with silicotic nodules released more hydrogen peroxide and PGE2 than those of control group(p<0.05). CONCLUSION: These results suggest that silica particle could activate macrophage directly and enhanced the release of PGE2 and hydrogen peroxide from the alveolar macrophage.

OBJECTIVE: Bilateral laminotomy and unilateral laminotomy for bilateral decompression are becoming the minimally invasive procedures for lumbar spinal stenosis (LSS). With the aim of less invasiveness and better preservation of spinal stability, these techniques have been developed. But there are no large randomized studies to show the surgical results between these two techniques. The objective of this study was to examine the safety and efficacy of these two minimally invasive techniques. METHODS: A total of 80 patients were included in this study (Group I : bilateral laminotomy, Group II : Unilateral laminotomy for bilateral decompression). Perioperative parameters and complications were analyzed. Symptoms and scores such as visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and SF-36 scores of prospectively accrued patients were assessed preoperatively and at 1 month and 12 months after surgery. Paired-t test, two-sample student-t tests, and nonparametric tests were used to determine cross-sectional differences between two groups. RESULTS: No major complications such as spinal instability or deaths occurred during follow-up periods. VAS, ODI scores and SF-36 body pain and physical function scores showed statistically significant improvements in both groups (p<0.001). The significant widening of the spinal canal diameter was also noted in both groups. But, in Group II, there were minor postoperative complications such as dural tear (2 cases 5.0%), fracture of ipsilateral inferior facet (1 case 2.5%), and 5 cases of transient leg symptoms of contralateral side. CONCLUSION: Both bilateral laminotomy and unilateral laminotomy for bilateral decompression allow achievement of adequate and long-lasting operative results in patients with LSS. But postoperative complications are more frequent in Group II (unilateral laminotomy and bilateral decompression). These results indicate that bilateral laminotomy is the preferred minimally invasive technique to treat symptomatic LSS.

Hand-foot-mouth disease (HFMD) is an infectious viral disease that is common among children. It is clinically characterized by vesicular eruptions on the palms and soles and a maculopapular rash. Onychomadesis is a periodic idiopathic shedding of the nails at their proximal ends and results from arrest of the proliferative function of the nail matrix. Recently, a few reports described onychomadesis following HFMD, although the mechanism remains unclear. To our knowledge, this association has not been reported in Korea. Herein, we report two cases of onychomadesis following HFMD and review the published data.
