Angioedma is a group of disorders with multifactorial etiology but a similar clinical expression, is characterized by swelling of subcutaneous or submucosal tissue. Systemic lupus erythematosus(SLE) is a chronic multi-systemtic disease characterized by inflammation and tissue damage resulting from deposition of auto-antibodies and immune complex. We experienced a case of angioedema which was the first manifestation of SLE in 24-year-old female patient. She had suffered from severe facial edema and multiple lymphadenopathy for six months and she also had pleural effusion, positive anti-nuclear and anti-DNA antibody test. Marked decrease of C3 and C4 levels was noted with normal antigenic level, and activity of Cl esterase inhibitor. The angioedema was not improved with anti-hitamine agents and instead disappeared with use of corticosteroid and non-steroidal anti-inflammatory drugs. Complement levels normalized after corticosteroid treament. We report a case of SLE which initial manifestation was angioedema.

Sarcomatoid carcinomas are malignant epithelial neoplasms in which the tumor cells assume a partial or complete spindle cell pattern of growth, leading to the erroneous classification of some true carcinomas as sarcomas. These spindle cells are malignant and manifest various amount of both vimentin and cytokeratin. Positive reaction of some of the spindle cells for cytokeratin antibodies is confirmatory. Clinical features do not differ significantly from those of patients with high-grade transitional cell carcinoma. So far, 13 cases of sarcomatoid transitional cell carcinoma of the renal pelvis have been reported in English and Korean literature. In this report, we describe clinicopathologic features of recently observed two cases of sarcomatoid transitional cell carcinoma of the renal pelvis and summarize the pathologic findings of previously reported cases with review of the literature.

This report presents the case of a 49-year-old man who presented with giant masses that had recently grown on the bilateral sides of the tongue. A clinical examination revealed rubbery yellowish lesions protruding from the tongue.A panoramic radiograph showed an enlarged soft tissue shadow of the tongue. Computed tomography showed well-defined circumscribed mass exhibiting a homogeneous low density on the bilateral sides of the tongue. On magnetic resonance images, the masses showed a high signal intensity on T1-weighted images and iso-signal intensity with partially hyperintense margin on fat-suppressed T2-weighted images. Surgical excision was performed, and a histopathologic examination confirmed the diagnosis of lipoma. The patient recovered well with no sign ofrecurrence. A giant lipoma is defined as a lipoma larger than 5 cm in diameter. A literature review of giant lipomas of the tongue is also presented herein.

Although occupational low back pain accounts for 20~40% of all occupational illness and injury, there are limited numbers of studies regarding the effectiveness of back school program. The objective of this study was to evaluate the economic benefit of back school program for early return to work of occupational low back pain patients in the current occupational injury compensation and management system. The cost-benefit analysis in this study was conducted to evaluate the relative magnitude of benefit to cost. The total cost was estimated by calculating the value of components in back school program according to governmental budget protocol. The back school program was consisted of three major approaches, pain center, work-hardening program and functional restoration program and each of components had various facilities and experts. The total amount of cost was estimated as 250,866,220 won per year. The most promising type of back school program were quite intensive (a 3 to 5-week stay in a specialized center), therefore, if we adopted the 5-week stay course, 10 courses could be held in a year. Following to the medical act, 20 patients per doctor could participate in a each course, ie, total 200 patients in a year. As a result, we could estimate the cost of 1,254,331 won a patient. we estimated the benefit by using data of a few local labor offices about average medical treatment beneficiary and off-duty beneficiary of 46 occupational low back pain patients in 1994. Ullman and Larsson(1977) mentioned that the group of chronic low back pain patients who participated in back school program needed less time to recover by 48.4% of beneficiary duration. And in the trying to estimate the benefit, we asked 10 rehabilitation board certificate doctors about reduction proportion of treatment cost by introducing back school program. The answered reduction proportions were in the range of 30~45%, average 39%. As a final result, we could see that the introduction of back school program in treatment of chronic occupational low back pain patients could produce the benefit to cost ratio as 3.90 and 6.28. And we could conclude that the introduction of back school program was beneficial to current occupational injury compensation and management system.

Neurofibromatosis 1(NF-1, Von Recklinghausen disease) and Neurofibromatosis 2(NF-2, bilateral acoustic neurinoma) have been established as distinct disorders by the National Institutes of Health(NIH) Consensus Development Conference in 1988. We recently have encountered a patient of NF-2 who develop multiple intracranial and spinal tumors 12 years after the surgical treatment of Schwannoma of lumbar nerve roots. The tumors were right acoustic neurinoma, left cerebellopontine angle(CPA) meningioma, multiple intracranial meningiomas, intraorbital glioma, multiple ependymomas of the brain stem and cervical spinal cord, and meningiomas of cervical nerve roots. We present this case with a review of reported cases of neurofibromatosis.

OBJECTIVE: The purpose of this study was to investigate the complication using carotid intima media thickness (CIMT) as an indicator for atherosclerosis and to verify the risk factors in systemic lupus erythematosus (SLE) patients compared with those of control group. METHODS: The study recruited 48 asymptomatic SLE and 32 healthy control group. These are examined by B-mode ultrasound (Acuson(TM) SequoiaC256 8 MHz linear transducer) to measure the CIMT at the far wall of the common carotid artery. A wide range of contribution factors to CIMT including age, body mass index, lipid profile, total cumulative steroid dose, SLEDAI, and proteinuria were considered. RESULTS: Although the results of CIMT in both groups were within normal limit (In healthy adult 0.25~1.5 mm, values > 1.0 mm often regarded as abnormal), the mean CIMT in patient group was 0.721+/-0.162 mm, which was thicker than that of control group with 0.5219+/-0.096 mm (p<0.001). In multiple regression analysis, only age showed significant contribution to CIMT (p<0.01). Disease duration, SLEDAI and serum lipids were of no statistical significance with CIMT. CONCLUSION: We were to elucidate the advance of atherosclerosis with measuring CIMT and assess factors associated with SLE. Even if the results of CIMT in both groups were within normal range, it is significant that the arterial thickening is more advanced in SLE than that of healthy control. Further studies based on CIMT are needed to screen and prevent cardiovascular complications from disease progression.

BACKGROUND: Everolimus and cyclosporine (CsA) exhibit synergistic immunosuppressive activity when used in combination. We analyzed preliminary data about the use of everolimus with a CsA-sparing strategy in de novo renal transplant recipients. METHODS: A comparative, parallel, randomized, open-label, 1 year study has been performed in 117 patients from 5 transplant centers to compare the efficacy and tolerability of everolimus (EVE)+reduced-dose CsA or enteric-coated mycophenolate sodium (Myfortic)+standard-dose CsA in combination with basiliximab and steroids. It ended on August 24, 2011. Efficacy failure (biopsy-proven acute rejection, death, graft loss, or loss to follow-up), safety, and renal function were evaluated at 1, 3, 5, and 12 months post-transplantation. RESULTS: Efficacy failure was comparable between the two groups. Only one graft loss has been reported in the control group and no patient death reported in either group. There was no significant difference in the incidence of biopsy-proven acute rejection until 3 and 5 month post-transplantation (P>0.05). The mean e-GFR of the group of EVE+reduced-dose CsA was significantly higher than that of the control group at 3 (65.6+/-16.9 mL/mim/1.73 m2 vs. 56.7+/-14.4 mL/mim/1.73 m2; P=0.007) and 5 (68.6+/-18.8 mL/mim/1.73 m2 vs. 58.1+/-16.2 mL/mim/1.73 m2; P=0.009) months. There was no significant difference in the incidence of discontinuations and serious adverse events between the groups (P>0.05). CONCLUSIONS: The regimen of EVE+reduced-dose CsA seems to be tolerated well, with comparable efficacy failure and better renal function than enteric-coated mycophenolate sodium+standard-dose CsA.

The principal significance of the urothelial changes caused by polyomavirus activation is in an erroneous diagnosis of urothelial cancer; however, the clue to their benign nature is the smooth structureless nuclear configuration and the relative paucity of affected cells. Though virologic studies and electron microscopy are usually needed to firmly establish the diagnosis, cytology is the most readily available and rapid means of establishing a presumptive diagnosis of human polyomavirus infection. A urine specimen of a 24-year-old man with hemorrhagic cystitis beginning two months after bone marrow transplantation for acute myeloblastic leukemia(M2) was submitted for cytologic evaluation. Cytologic findings revealed a few inclusion-bearing epithelial cells intermingled with erythrocytes, neutrophils, lymphocytes, and macrophages. Most of the inclusion-bearing -cells had large, round to ovoid nuclei almost completely filed with homogeneous dark, basophilic inclusion. The chromatin was clumped along the periphery and the cytoplasm was mostly degenerated. The other cells exhibited irregular inclusions attached to the nuclear membrane surrounded by an indistinct halo. These findings were consistent with polyomavirus infection.

A 16-year-old male presented with pain in the right posterior mandible on chewing that had lasted for several months. The radiographic features of the lesion included a radiolucent-radiopaque mixed-density mass with a radiolucent rim attached to the root of the mandibular right first molar. The preliminary radiographic diagnosis was benign cementoblastoma, which was confirmed by histopathological examination following surgical excision. The lesion recurred 3 years after treatment; radiographically, it consisted of 3 round foci with mixed radiopacity, each with a radiolucent rim near the root of the mandibular right second premolar and the edentulous postoperative region. The lesion was diagnosed as recurrent benign cementoblastoma and a second surgery was scheduled. This report presented an unusual case of recurrent benign cementoblastoma following surgical excision and extraction of the involved tooth, along with a literature review on reported cases of recurrent benign cementoblastoma with a focus on its clinical features and the best treatment options.
