Superficial Fibromatosis Mimicking Glomus Tumor of the Second Toe

Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The presentation of this condition shows the possibility of encountering uncommon superficial fibromatosis in the distal phalanx of the toe, and suggests that superficial fibromatosis should be included in the differential diagnosis of a glomus tumor in the toe.

Analysis of Clinical Features of Hip Fracture Patients with or without Prior Osteoporotic Spinal Compression Fractures

BACKGROUND: To analyze and compare the clinical characteristics including bone mineral density (BMD) in a group who had operation of hip fracture with or without prior osteoporotic spinal compression fractures. METHODS: Two hundred forty patients who had undergone operation of hip fractures were evaluated, 127 patients who had with prior osteoporotic spinal compression fractures were in group I, and 113 patients without prior spinal fractures were in group II. In each group, we measured age, gender, body mass index (BMI, kg/m2), BMD (mg/cm3), type of hip fractures, concomitant diseases, presence of secondary hip fracture and history of percutaneous vertebroplasty. RESULTS: The mean age of group I was 79.4 years (male/female: 28/99) and that of group II was 77.6 years (male/female: 37/76). The mean BMI of group I was 21.3 kg/m2 and that in group II was 22.0 kg/m2. The mean BMD and T-score of group I were 41.1 mg/cm3 and -4.45 and those in group II were 51.0 mg/cm3 and -4.17 (P<0.05). The numbers of patients of neck and intertrochanter fracture of group I were 31 and 96 patients and those in group II were 61 and 52 patients. Sixty in group I and 45 in group II patients had concomitant diseases. Thirteen patients had undergone percutaneous vertebroplasty and 18 patients (7.5%) had second hip fractures. CONCLUSIONS: The hip fracture patients who had with prior osteoporotic spinal compression fractures had lower BMD compared to the hip fracture patients without previous spinal compression fractures.

Osteoporotic Lumbar Compression Fracture in Patient with Ankylosing Spondylitis Treated with Kyphoplasty

Ankylosing spondylitis (AS) is an inflammatory disease primarily affecting the spine. Osteoporosis can be a complication of AS and associated with low bone mineral density. As well, spinal fractures in the AS are usually unstable and may cause neurologic deficit at the mainly cervical region with low energy trauma. However, reports of lumbar compression fracture in AS are very rare. Thus, we report a 73-year-old male patient with osteoporotic L3 compression fracture with AS treated with kyphoplasty which has no symptom improvement with conservative treatment. Kyphoplasty is a useful procedure option in the treatment of the lumbar compression fracture in AS.

Hallux Rigidus with Osteochondroma of the Hallucal Proximal Phalanx (A Case Report) / 대한족부족관절학회지

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

Clinical Characteristics of Ankle Fracture in Osteoporotic Patients Over Sixty-five Years of Age / 대한골다공증학회지

OBJECTIVES: Fracture of multiple sites can occur by minor trauma because decreased bone quality and bone density in osteoporotic patients. To investigate clinical characteristics of ankle fracture in osteoporotic patients over sixty-five years of age. MATERIALS AND METHODS: From January 2009 to December 2011, excluding distal tibial shaft and pilon fracture, 40 patients (over 65 years old) who were diagnosed the osteoporosis and observed over 6 months after ankle surgery. We measured age, gender, body mass index (BMI, kg/m2), bone mineral density (BMD, mg/cm3) and T-score through P-QCT. Type of fracture was classified into Danis-Weber and AO classification and whether or not of syndesmotic injury and concomitant disease. Surgery performed under AO principle. We investigated by wound healing, fixation failure and bone union during follow-up.

Analysis of Osteoporotic Spinal Compression Fractures in Whole Spine Sagittal MR Images

OBJECTIVES: To analyze the fracture type and adjacency of accompanied fractures in acute osteoporotic spinal compression fracture using whole spine sagittal MRI (WS-MRI), and to know the relation of sagittal vertical axis (SVA), body mass index (BMI), and lumbar bone mineral density (BMD). METHODS: From June 2007 to December 2010, 167 patients who had acute spinal compression fractures confirmed by WS-MRI divide in three groups. 82 patients (M/F : 25/57) who had acute fractures only were in group 1, 79 patients who had acute and old fractures were in group 2, and 20 patients who had acute fractures after vertebroplasy were in group 3. To analyze the fracture type and adjacency of accompanied fractures in acute osteoporotic spinal compression fractures which combined chronic fracture or vertebroplasty using the WS-MRI and compared with the control group who had no spinal fractures measured the SVA. In all groups, we measured BMI, and BMD. RESULTS: In WS-MRI, 31 patients in group 1 had L1 which was the most common fracture site. Twenty two patients had chronic fractures and more than 3 remote levels at the acute fracture site in group 2 and especially among there 14 patients have each level in cervicothoracic and lumbar vertebrae. In group 3 had old fracture and adjacent fracture was 14 and 11 patients. Compared with the control group, all groups had increased SVA, especially in group 2 which has acute and chronic compression fractures. They have no significantly difference of BMI in each group, but group 2 and 3 had a significant lower BMD than group 1. CONCLUSION: Fourteen patients of coexisting fractures in acute osteoporotic spinal compression fractures with WS-MRI which could be missed in the conventional MRI. Additionally this study suggests that longer SVA causes sagittal imbalance, and BMD is more relative than BMI in refractures of chronic compression fracture patients.

The Association between the Bone Mineral Density and Spinal Osteoarthritis in Osteoporotic Thoracolumbar Compression Fractures

OBJECTIVES: The purpose of this study was to determine the association between the bone mineral density (BMD) and severity of spinal osteoarthritis (spondylosis) in osteoporotic spinal compression fracture. METHODS: Fifty six patients were evaluated 66 cases had an osteoporotic thoracolumbar compression fracture between January 2008 and June 2010. The average patient age was 76.2 years (M/F : 8/48). Age and body mass index (BMI, kg/m2) were measured, and the BMD was performed using peripheral quantitative computed tomography (pQCT). Simple thoracolumbar (T-L) spine lateral radiography was evaluated for three criteria: presence of osteophytes, disc space narrowing and vertebral body sclerosis. The findings were graded 0 to 3 and analyzed statistically for a correlation with the BMD and fractured vertebrae. RESULTS: Acute compression fractures comprised of 15 cases and the most common site of acute fractures with old fractures was lumbar spine (L1; 30 cases, 45.4%). The average of BMI was 23.32 and BMD (T-score) was -4.47. Pearson's rho showed a positive association between the weight, height and the BMD (P < 0.01). In terms of the BMD versus spondylosis, there was a positive association with high score in the high order cortical bone. Compression fractures occurrence rate in the absent and present of spondylosis was 74.3% and 22.4%, and 69% occur in the spinal segmental with no bony spur with chi-square test (P < 0.01). CONCLUSION: In the present of spondylosis was high score of cortical BMD and low rate of compression fracture. Spondylosis could be one of a factor of the occurrence in acute and adjacent compression fracture after old fractures.

Deep Vein Thrombosis after Fusion Operation of Osteoporotic Spinal Compression Fracture / 대한골다공증학회지

The risk of deep vein thrombosis (DVT) is well studied for some orthopedic surgery. However, the incidence of postoperative DVT is less well-defined in patients who have spinal surgery. In addition, there is insufficient evidence to suggest that screening patients before spinal surgery and to use of prophylactic method such as anticoagulants, compression stockings, and pneumatic compression device. We experienced a 78-year-old female patient of DVT after fusion operation with pedicular screws in T12 osteoporotic compression fracture. As risk of DVT after major spinal surgery is fairly low, it seems reasonable to consider prophylactic management after spinal surgery in old aged patients with difficult ambulation.

Comparison of Adjacent Spinal Compression Fracture after Old Osteoporotic Spinal Compression Fracture and Percutaneous Vertebroplasty / 대한골다공증학회지

OBJECTIVES: New adjacent spinal compression fractures occur not only in patients with osteoporotic spinal compression fractures after vertebroplasty but also in untreated old spinal compression fractures. The objective was to analyze and compare the characteristics in a group who had untreated old osteoporotic spinal compression fractures with those who had adjacent spinal compression fractures, which occurred after a vertebroplasty. MATERIALS & METHODS: From April 2006 to April 2009, 103 patients who had undergone vertebroplasty were evaluated. Eighteen patients (22 cases) who had untreated old osteoporotic spinal compression fractures were in group I, and 12 patients (13 cases) who had adjacent spinal compression fractures, which occurred after a vertebroplasty were in group II. In each group, we measured age and gender, body mass index (BMI), lumbar bone marrow density (BMD), sagittal index, and compression rate at the initial fracture site.

The Efficacy of Epidural Ketamine on Shivering during Transurethral Resection of the Prostate under Epidural Anesthesia / 대한배뇨장애요실금학회지

PURPOSE: Ketamine may decrease core-to-peripheral redistribution of heat through direct central sympathetic stimulation and inhibition of norepinephrine uptake into postganglionic sympathetic nerve endings. The purpose of this study was to evaluate the efficacy of epidural ketamine in preventing shivering during transurethral resection of the prostate (TURP) under epidural anesthesia. MATERIALS AND METHODS: Ninety-three male patients scheduled for TURP under epidural anesthesia were enrolled in this study. Patients were randomized into one of three groups. Group 1 consisted of 31 patients who received epidural 0.75% ropivacaine, group 2 consisted of 32 patients who received epidural ketamine (0.2 mg/kg) in addition to 0.75% ropivacaine, and group 3 consisted of 30 patients who received epidural ketamine (0.4 mg/kg) in addition to 0.75% ropivacaine. Shivering and side effects such as hypotension, bradycardia, nausea, and hallucination were recorded during the anesthesia and for 2 hours while in the postanesthetic recovery room. RESULTS: Shivering was statistically more frequent in group 1 than in the other groups. The incidence of sedation was significantly higher in group 3 than in the other groups. The incidences of side effects such as hypotension, bradycardia, and nausea were significantly higher in group 1 than in the other groups. CONCLUSIONS: In this study, epidural ketamine 0.2 mg/kg and 0.4 mg/kg was shown to have a lower incidence of shivering and other side effects except sedation. In patients who undergo TURP under epidural anesthesia, the prophylactic use of low-dose epidural ketamine would be helpful in preventing any adverse effects, including shivering.

Safety of Laparoscopic Radical Nephrectomy in the Elderly Patients

BACKGROUND: Elderly patients with underlying cardiovascular or respiratory diseases are more susceptible to anesthesiologic risks or serious complications following laparoscopic operations. We evaluated the safety of laparoscopic radical nephrectomy in elderly patients to compensate for the lack of Korean data on the subject in the field of urology. METHODS: From March 2003 and March 2009, 73 patients with localized renal cell cancer underwent laparoscopic radical nephrectomy. They were divided into two groups according to age; 75 years or older (elderly group, n=21) and under 75 years (young group, n=52). Operative parameters as well as oncological outcomes were evaluated. RESULTS: The mean age was 77.7+/-2.5 years for the elderly group and 55.9+/-10.5 years for the young group. No significant differences existed between the groups in terms of mean operative time, intraoperative blood loss, complications, and hospital stay. However, American Society of Anesthesiologists (ASA) score, co-morbidities (p<0.05), and rate of transfusion (p<0.05) were significantly higher in the elderly group. In overall analyses, we conclude that in elderly patients undergoing laparoscopic radical nephrectomy, close monitoring of hemoglobin level as well as intraoperative transfusion for maintenance of hemoglobin level at 10 mg/L or higher is necessary in elderly patients to achieve adequate circulation. CONCLUSION: Laparoscopic radical nephrectomy can be considered a safe and effective procedure for most elderly patients.

Circadian Effects on Neural Blockade of Intrathecal Hyperbaric Bupivacaine

BACKGROUND: Circadian variations in the absorption, distribution, protein binding, elimination and metabolism of drugs account for many of the administration-time-dependent differences in their pharmacokinetics. The aim of this study is to determine whether the time of intrathecal injection influences spinal anesthesia. METHODS: Ninety patients scheduled for orthopedic surgery were randomly assigned to three groups. Each group received spinal anesthesia with 0.5% bupivacaine 10 mg at different times; group AM (8 am to 12:00), group Noon (12:00 to 4:00 pm) and group PM (4:00 pm to 8:00 pm). Sensory and motor blockade were assessed by pinprick and a four-point modified Bromage scale. Time to first postoperative analgesic requirement and side effects such as hypotension, bradycardia, nausea, and shivering were recorded. RESULTS: No significant differences were found among the three groups in peak sensory blockade, duration of motor block to Bromage 1 or side effects, but time to first postoperative analgesic requirement (P = 0.008), and recovery time of S1 sensation to pinprick were significantly prolonged in group Noon compared with the other groups (P = 0.03). CONCLUSIONS: The tine of administration of spinal local anesthetics influences the duration of local anesthesia.

Is Complex Regional Pain Syndrome a Cause of Post-Operative Syndrome in the Lumbar Spine?: A Case Report

Complex regional pain syndrome (CRPS) along with post-operative syndrome in the lumbar spine shows confusing and duplicated symptoms, and this makes it difficult to make a clear differential diagnosis. Therefore, the patient with post-operative syndrome in the lumbar spine suffers losses of time and money, and the surgeon who diagnoses and treats post-operative syndrome in the lumbar spine also agonize from the patient's losses. It is necessary to provide these patients with a multidisciplinary approach to their disease and symptoms. We diagnosed herniation of an intervertebral disc of the lumbar spine (L4/5) and we performed discetomy twice in different hospitals. However, the symptoms did not improve, so we re-operated and performed discetomy along with monosegmental fixation using pedicular screws and interbody cages. There was improvement of pre-operation symptoms, but neurogenic symptoms occurred and then progressed after the surgery. Therefore, we report here on the case of CRPS that was diagnosed with the exclusion of the causes of post-operative syndrome in the lumbar spine, and the patient was finally effectively treated with spinal cord stimulation. Although differentiating post-operative syndrome in the lumbar spine from CRPS is difficult, we recommend suspecting CRPS as the cause of post-operative syndrome in the lumbar spine and taking CRPS as the main interest in order to diagnose and treat CRPS more effectively and accurately.

Rebamipide Protects Colonic Damage Induced by Trinitrobenzene Sulfonic Acid (TNBS) via Down-Regulation of TNF-alpha IL-1beta and ICAM-1 / 대한해부학회지

During inflammation of the colon, cells of the gut mucosa produce or express numerous inflammatory mediators, such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1 beta), and intercellular adhesion molecule 1 (ICAM-1). These mediators have been implicated as contributory factors to the inflammatory process, which results in colitis during inflammatory bowel disease (IBD). Rebamipide is an anti-gastric ulcer drug with anti-inflammatory properties in vivo and in vitro. The effects of Rebamipide on IBD have not been largely evaluated. Therefore, this study investigated the potential of Rebamipide to regulate the production of inflammatory mediators such as TNF-alpha, IL-1beta, and ICAM-1. Mice with trinitrobenzene sulfonic acid (TNBS)-induced colitis (IBD animal model), were treated intrarectally with 2 mM Rebamipide. Body weight, macro- and micro-histological scores, and activity were evaluated. As an index of tissue edema, the thickness of the colonic wall was measured between the serosal surface and the luminal surface of the mucosa. TNF-alpha, IL-1 beta, and ICAM-1 were detected by immunohistochemical staining. Rebamipide treatment of mice exhibiting TNBS-induced colitis dramatically improved the clinical and histopathological findings of inflammation. In addition, Rebamipide suppressed TNF-alpha, IL-1 beta, and ICAM-1 expression in TNBS-treated animals. Taken together, these findings suggest that Rebamipide is a potential therapeutic agent for treating patients with IBD.

Gliotoxin Protects Against TNBS-induced Colitis Via Down-regulation of NF B Activation / 대한해부학회지

During inflammation of the colon, cells of the gut mucosa express numerous inflammatory mediators including interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta(IL-1beta). These cytokines have been implicated as contributing factors in the inflammatory process, which may result in colitis during inflammatory bowel disease (IBD). Gliotoxin is a fungal metabolite of an epipolythiodioxopiperazine analogue with immunosup-pressive properties in vivo and in vitro, but the effects of gliotoxin on IBD have not been largely evaluated. Therefore, this study evaluated the potential of gliotoxin to protect against TNBS-induced colitis. One microgram of gliotoxin in 100microliter of vehicle was intra-rectally administered into mice exhibiting trinitrobenzene sulfonic acid (TNBS)-induced colitis. IL-8 secretion was measured using an enzyme-linked immu-nosorbent assay (ELISA), myeloperoxidase (MPO) activity was evaluated spectrophotometically, and IkappaB degradation was analyzed on Western blots. Gliotoxin treatment of mice bearing TNBS-induced colitis improved macro-and micro-pathological findings and dramatically decreased MPO activity, a marker of leukocyte infiltration. Furthermore, gliotoxin decreased IkappaB degradation and IL-8 induction caused by TNF-alpha or IL-1beta in HT-29 cells. These findings suggest that gliotoxin partially protects against TNBS-induced colitis through the sup-pression of IL-8 induction and IkappaB degradation by inflammatory mediators such as TNF-alpha or IL-1beta.

A Case of Malignant Hyperthermia during General Anesthesia with Sevoflurane: A case report / 대한마취과학회지

We experienced a malignant hyperthermia in 24-year-old male with sevoflurane during the mandibular prognathism surgery. The malignant hyperthermia emerged 150 minutes after induction of general anesthesia using propofol, rocuronium, sevoflurane, N2O and O2. Sevoflurane has been reported that it can induce delayed onset of malignant hyperthermia under absence of succinylcholine. The prognosis of malignant hyperthermia is determined by early recognition, vigorous treatment and the time of dantrolene injection. In our case, when we suspected episode, all anesthetics were stopped and dantrolene injection was immediately given intravenously. The patient recovered normal temperature and consciousness without any complication.

Protective Effect of PKC and Nitric Oxide Affecting Taxol-Induced Cytotoxicity in C6-Gial Cells / 대한해부학회지

Paclitaxel (Taxol) is known as effective drug for inhibition of cell cycle encouraging in human cancer cells. This drug named an antimicrotubule agent which simulate the mitotic arrest towards an apoptosis. The influence of phorbol 12 myristate 13 acetate (PMA) activated protein kinase C (PKC) and nitric oxide (NO) on taxol-induced apoptosis, is poorly understood. To investigate the effects of PMA and NO on the signal transduction in taxol-induced apoptosis in C6-glial cells, the viability and caspase-3 activity of C6-glial cells were analyzed. Pretreatement with PKC activatior (PMA) protected taxol-induced cell death in C6-glial cells, by inhibited caspases-3 activity. On the other hand, the taxol-induced apoptosis was highly enhanced by sodium nitroprusside (SNP) and lipopolysaccharide (LPS), as NO activator. These results suggest that PMA strongly blocks the apoptotic effect of taxol, while nitric oxide has no protective effects in the process of toxol-induced apoptosis in C6-glial cells.
