STUDY DESIGN: We report two cases of symptomatic spinal epidural lipomatosis (SEL) associated with long-term use of steroid medication OBJECTIVES: The purpose of this study was to assess the clinical characteristics, diagnosis and treatment of symptomatic spinal epidural lipomatosis. SUMMARY OF LITERATURE REVIEW: Spinal epidural lipomatosis is a condition in which excess adipose tissue is deposited circumferentially about the spinal cord in the epidural space. It can present neurologic symptoms including back pain, radiculopathy or cauda equina. Magnetic resonance imaging is the most helpful dignostic means and should be used initially if suspected. Treatment is decompressive laminectomy and debulking of fat. MATERIALS AND METHODS: Two cases of lumbar epidural lipomatosis with neurologic symptoms were discussed and evaluated by physical examination, postmyelography CT and MRI. RESULTS: Two cases were treated with decompressive laminectomy and debulking of fat. Increased accumulation of the fatty tissue was seen predominently in posterior and posterolateral epidural space of the spinal canal, displacing and compressing the lumbar spinal cord anteriorly. Both gross and histologic evaluation revealed overgrowth of unencapsulated normal appearing fat consistent with spinal epidural lipomatosis. One case was demonstrated gradual improvement in symtoms after operation but the other was died due to medical problems. CONCLUSION: The authors reviewed the literature and reported the results of operative treatment of patients with lumbago, radicular pain and intermitent claudication caused by epidural lipomatosis of lumbar spine and degenerative spinal stenosis.

BACKGROUND: The objective responses of cisplatin and etoposide (PVP) combination chemotherapy as second-line therapy following CAV was high (40~50%) and, in several reports, PVP yields survival results that are at least as good as those obtained with cyclophosphamide or doxorubicin-based regimens and with less host-related toxicity in chemotherapy-naive patients. We conducted a phase II study to evaluate the effect of a combination of cisplatin and etoposide as a first-line therapy in patients with small cell lung cancer. METHODS: Sixty-one previously untreated small cell lung cancer patients with measurable lesion(s) received cisplatin(30 mg/m2 IV, day 1~3) and etoposide(100 mg/m2 IV, day 1~3). In patients with limited disease, after completion of 6 cycles of PVP chemotherapy, chest and prophylatic brain irradiation was performed in case of complete responder, chest irradiation only in partial responder. RESULTS: 1) Of 55 evaluable patients, 13(24%) had a complete response and 29(53%) had a partial response. 2) The median survival time was 55.8 weeks for all patients(N=55), 61.1 weeks for limited disease(N=31), 51.3 weeks for extensive disease(N=24). 3) The response duration was 29.1 weeks for responders(N=42). 4) There was no significant prognostic factors iufluencing response rates. 5) The toxicity was tolerable and there was no treatment-related deaths. CONCLUSION: The PVP combination chemotherapy as a first-line therapy was effective and well-tolerated in patients with small cell lung cancer.

BACKGROUND: Post-operative shivering is one of the potential complications for any surgical patient. Its incidence varies from 5% to 65%, and many preventive and treatment modalities have been reported. For the effective prevention of post-anesthetic shivering by using intravenous clonidine or meperidine, randomized controlled studies were reviewed. The overall incidence of shivering after clonidine or meperidine administration, and the anti-shivering effect of clonidine and meperidine were evaluated. METHODS: DATA SOURCES: Medline search from 1978 to March 1998. DATA SELECTION: We selected studies that had investigated the preventive anti-shivering effect of intravenous clonidine or meperidine by randomized controlled trials. Ten clinical trials were evaluated. RESULTS: The pooled odd ratio of the patients who received clonidine was 0.32 (95% confidence interval, 0.22~0.47) and it seemed to be effective. But these studies showed little evidence of significant homogeneity (P=0.01). In the subgroup analysis, the pooled odd ratio of group A (early administration or intra-operative infusion group) was 0.47 (95% CI 0.31~0.72) evidenced effectiveness but failed to prove homogeneity (P=0.047). But group B (the late intra-operative administration group) had a pooled odd ratio of 0.10 (95% CI 0.05~0.22) and showed homogeneity (P=0.98). In meperidine trials, the pooled odd ratio was 0.20 (95% CI 0.07~0.55). CONCLUSION: We present quantitative evidence based on a meta-analysis of pooled effect size from randomized trials that clonidine is more beneficial for the prevention of post-anesthetic shivering and more effective than meperidine when it is administrated during later period of surgery.

Headache disorders, one of most common disease in general population, have been developed according to many versions of international classifications. The primary headaches are those in which no consistently identified organic cause can be determined. It is divided into the following categories: (1) migraine, (2) tension-type headache, (3) cluster headache and other trigeminal autonomic cephalalgias, (4) other primary headaches. This review described a diagnosis of primary headache disorders based on International Classification of Headache Disorders (ICHD)-3 beta criteria.

BACKGROUND: Pulmonary Langerhans cell histiocytosis forms part of a spectrum of diseases that are characterized by a monoclonal proliferation and infiltration of organs by Langerhans cells. Several organ systems may be involved in Langerhans cell histiocytosis, including the lungs, bone, skin, pituitary gland, liver, lymph nodes and thyroid. Pulmonary histiocytosis X represents 2.8% of interstitial lung disease. Here we present the clinical, radiological, therapeutic aspects of pulmonary histiocytosis X. METHOD: Fourteen cases of biopsy-proven pulmonary histiocytosis X patients who were diagnosed in Seoul National University Hospital during the period from January 1990 to December 1998 were analyzed retrospectively. RESULT: There were 12 men and 2 women in this study. The initial presenting symptoms were dyspnea, cough, chest pain, which was associated with the pneumothorax, and chest radiography abnormalities. Only 8 patients (57%) were smokers. There were 5 patients with extra-pulmonary histiocytosis (pituitary, bone, skin). Eight patients had received the chemotherapy. There were no mortalities and only one patient experienced an aggravation of symptom during the follow-up period. CONCLUSION: In contrast to previous reports from other countries, the patients with pulmonary histiocytosis X in this study presented with several different clinical characteristics, such as a male predominance, relatively low smoker's rate, and a better prognosis.

A femoral neck stress fracture in child is rare, particularly in bilateral case. It is easy to miss initially or may be misdiagnosed. The authors experienced a case of bilateral femoral neck stress fracture in a 10-year-old boy with bilateral hip. The patient was successfully healed by conservative treatment. We report this rare case with a review of the literature. A femoral neck stress fracture should be included in the differential diagnosis in children who present with sustained hip or groin pain.

An anomalous systemic arterial supply to the normal basal segments of the left lower lobe without sequestration is a rare congenital anomaly. It differs from classical bronchopulmonary sequestration in that the involver lung retains a normal connection to the bronchial tree, although some place this entity exists within the broad framework of pulmonary sequestration. We experienced a case of a woman who presented with a nodular lesion on a chest X-ray. Contrast-enhanced CT diagnosed her as having an anomalous systemic arterial supply to the normal basal segments of the left lower lobe. This case is reported with a brief literature review.

BACKGROUND: Early stage osteonecrosis of the femoral head (ONFH) has many treatment options including core decompression with implantation of a tantalum rod. The purpose of this study was to evaluate clinical and radiological outcomes and potential complications during conversion total hip arthroplasty (THA) in such patients. METHODS: Six male patients (8 hips) underwent THA subsequent to removing a tantalum rod (group I) from April 2010 to November 2011. We retrospectively reviewed the medical records of these patients. We enrolled 12 age- and sex-matched patients (16 hips) during the same period, who had undergone primary THA without a previous operation as the control group (group II). All patients were followed for at least 3 years. We checked the Harris hip score (HHS), operative time, and volume of blood loss. Radiological results, including inclination, anteversion of the acetabular cup, presence of periprosthetic osteolysis, and subsidence of femoral stem were checked at the last follow-up. RESULTS: The mean preoperative HHS values were 56.5 (range, 50 to 62) and 59.1 (range, 42 to 70) in groups I and II, respectively. The HHS improved to 96.0 (range, 93 to 100) and 97.6 (range, 93 to 100), respectively, at the 3-year follow-up (p = 0.172). Mean operation time was 98.8 minutes (range, 70 to 120 minutes) in group I and 77.5 minutes (range, 60 to 115 minutes) in group II (p = 0.006). Total blood loss volumes were 1,193.8 mL (range, 960 to 1,360 mL) and 944.1 mL (range, 640 to 1,280 mL) in groups I and II, respectively (p = 0.004). No significant differences in inclination or anteversion of acetabular cup and no evidence of osteolysis or subsidence of the femoral stem were reported in either group in radiological follow-up results. However, one case of squeaking occurred in group I during the follow-up. CONCLUSIONS: The two groups showed no clinical or radiological differences except extended operative time and increased blood loss. However, the incidence of squeaking (1 of 8 hips) was higher, as compared to the control group or previously reported values.

BACKGROUND: The objective of this study was to compare clinical and radiological outcomes of total hip arthroplasty (THA) between ankylosing spondylitis (AS) of the hip joint and avascular necrosis (AVN) of the femoral head. METHODS: Thirty patients (30 hips) underwent cementless THA for AS between 2003 and 2012. They were compared to 30 patients (30 hips) who underwent the same procedure for AVN of the femoral head. Each group was matched for age and gender, and both groups had similar preoperative demographic characteristics. All cases were followed for minimum 4 postoperative years. Clinical evaluation was based on operation time, intraoperative blood loss, quantity of postoperative drainage, Harris Hip Score (HHS), and range of motion (ROM). Radiological results were evaluated by acetabular cup anteversion and inclination, femoral stem orientation, pre- and postoperative leg length discrepancy, and postoperative complications. RESULTS: The operation time was significantly longer in the AS group (120.2 ± 26.2 min) than in the AVN group (79.5 ± 11.1 min). The volume of postoperative drainage was significantly greater in the AS group (764.5 ± 355.4 mL vs. 510.5 ± 195.6 mL). Preoperative HHS was lower in the AS group (55.6 ± 13.8 vs. 59.2 ± 2.8). Similarly, postoperative HHS was significantly lower in the AS group (92.8 ± 2.7 vs. 97.4 ± 2.6). The arc of ROM was improved from 146.5°± 13.2° preoperatively to 254.7°± 17.2° postoperatively in the AS group and from 182.6°± 15.5° to 260.4°± 13.7° in the AVN group. Implant position and postoperative leg length discrepancy were not different between the groups. However, three cases of heterotopic ossification was observed in the AS group, whereas only 1 case was found in the AVN group. One deep infection and one aseptic stem loosening were found in the AS group, whereas none was observed in the AVN group. CONCLUSIONS: Cementless THA showed satisfactory clinical and radiological results in both groups, despite the longer operation time, larger blood loss volume, and lower HHS score of the AS group. Our findings suggest that cementless THA is an effective and reliable treatment for both AS and AVN.
