Tracheal tumors are uncommon comprising less than 0.1% of all malignancies. Metastatic tracheal tumors, especially form the extrathoracic sites, are exceedingly rare. Ovarian cancer tends to metastasize to the serous cavities and the lymph nodes. One large autopsy study reported tracheal involvement in 1% of patients who had died from ovarian cancer. Other studies have not mentioned tracheal involvement at all. Since the main symptoms of cough, hemoptysis, or wheezing are nonspecific, patients may be initially treated for other conditions including asthma or bronchitis. Here we describe a metastatic tracheal tumor from an overain carcinoma that was initally treated for bronchial asthma.

PURPOSE: We performed this study to describe the findings of MR Myelography(MRM) of herniated disc disease, spinal stenosis and spinal tumor and to evaluate the usefulness of the MRM in comparison to MRI. MATERIALS AND METHODS: MRI and MRM were performed in 31 patients with herniated disc disease(12 patients), spinal stenosis(11 patients) and spinal tumor(8 patients). MRI and MRM were done with 1.5-T Signa MR, using fat suppressed heavily T2-weighted fast spin echo technique. We retrospectively analyzed MRM images about the thecal sac indentation, compression or displacement of the nerve root, extent and degree of narrowing of spinal canal, relationship between spinal tumor and spinal cord. MRM findings were compared with MRI in all cases. RESULTS: In 18 herniated disc cases of 12 patients, focal filling defect with cutoff or displacement of the nerve root in eight cases of paracentral herniated disc was seen. Cutoff and displacement of the nerve root were more clearly delineated on MRM than rvlRI. In the patients of spinal stenosis(11 cases), hourglass deformity of the thecal sac or complete spinal block of the subarachnoid space was clearly demonstrated. The extent and severity of spinal stenosis were more accurately evaluated on MRM than MRI. MRM finding of intramedullary tumor(3 cases) was enlargement of spinal cord. Five cases of intradural extramedullary tumor showed intradural filling defect, which caused contralateral displacement of the spinal cord with meniscus sign on inferior margin of the mass. CONCLUSION: MRM shows characteristic findings of herniated disc disease, spinal stenosis and spinal tumor. MRM yields excellent definition of the thecal sac, nerve roots and nerve root sleeves in relation to herniated disc and may be more accurate in evaluation of the degree and extent of spinal stenosis than MRI.

There are numerous agents with potential toxic effects on the lung. In particular, cytotoxic drugs constitute the largest and most imprtant group of agents associated with lung toxicity. Bleomycin is commonly used, either alone or in combination with other chemotherapeutic agents, in the treatment of squamous cell carcinoma(head and neck, esophagus, and genitourinary tract), lymphoma, and germ cell tumor. One of the therapeutic advantages of bleomycin is its minimal bone marrow toxicity. However, pulmonary toxicity is one of the most serous adverse side effect. Classically, pulmonary toxicity manifests as a diffuse interstitial process or less commonly as a hypersensitivity reaction. This pulmonary toxicity is generally considered to be dose related and can progress to a fatal fibrosis. It is also possible that bronchiolitis obliterans organizing pneumonia(BOOP) is another manifestation of bleomycin induced toxicity. Bleomycin induced BOOP is less common and has a favorable response to steriod therapy. Here we present a case that demonstrates a BOOP, secondary to a relatively small cumulative dose of bleomycin(225mg/??, may be reversible.

The stems of Oplopanax elatus (OE) have long been used to treat inflammatory disorders in herbal medicine, and in the previous investigation, OE was found to possess anti-inflammatory activity in lipopolysaccharide-treated macrophages, RAW 264.7 cell. OE reduces inducible nitric oxide (NO) synthase-induced NO production, and interferes with mitogen-activated protein kinase activation pathways. In the present study, the pharmacological action of the water extract of OE was examined to establish anti-arthritic action, using a rat model of adjuvant-induced arthritis (AIA). The water extract of OE administered orally inhibited AIA-induced arthritis at (100 – 300) mg/kg/day. The paw edema was significantly decreased, in combination with reduced production of pro-inflammatory cytokines. The action mechanism includes an inhibition of MAPKs/nuclear transcription factor-κB activation. These new findings strongly suggest that OE possesses anti-arthritic action, and may be used as a therapeutic agent in inflammation-related disorders, particularly in arthritic condition.

The aim of our study was to evaluate the utility and diagnostic accuracy of the ossification grade of medial clavicular epiphysis on chest radiographs for identifying Korean adolescents and young adults under the age of majority. Overall, 1,151 patients (age, 16-30) without any systemic disease and who underwent chest radiography were included for ossification grading. Two radiologists independently classified the ossification of the medial clavicular epiphysis from chest radiographs into five grades. The age distribution and inter-observer agreement on the ossification grade were assessed. The diagnostic accuracy of the averaged ossification grades for determining whether the patient is under the age of majority was analyzed by using receiver operating characteristic (ROC) curves. Two separate inexperienced radiologists assessed the ossification grade in a subgroup of the patients after reviewing the detailed descriptions and image atlases developed for ossification grading. The median value of the ossification grades increased with increasing age (from 16 to 30 years), and the trend was best fitted by a quadratic function (R-square, 0.978). The inter-observer agreements on the ossification grade were 0.420 (right) and 0.404 (left). The area under the ROC curve (AUC) was 0.922 (95% CI, 0.902-0.942). The averaged ossification scores of 2.62 and 4.37 provided 95% specificity for a person < 19 years of age and a person ≥ 19 years of age, respectively. A preliminary assessment by inexperienced radiologists resulted in an AUC of 0.860 (95% CI, 0.740-0.981). The age of majority in Korean adolescents and young adults can be estimated using chest radiographs.

The most common manifestation of multiple endocrine neoplasia type 1 (MEN1) is hyperparathyroidism. Treatment of hyperparathyroidism in MEN patients is surgical removal of the parathyroid glands, however ectopic parathyroid gland is challenging for treatment. A 51-year-old female, the eldest of 3 MEN1 sisters, had hyperparathyroidism with ectopic parathyroid adenoma in the mediastinal para-aortic region, which was detected by technetium-99m (Tc-99m) sestamibi scintigraphy and single-photon emission computed tomography/computed tomography (SPECT/CT). She underwent total parathyroidectomy with video-assisted thoracoscopic surgery on an anterior mediastinal mass. Anterior mediastinal parathyroid adenoma in MEN1 patients is rare. Precise localization of an ectopic parathyroid gland with Tc-99m sestamibi SPECT/CT can lead to successful treatment of hyperparathyroidism. This is the first reported case in the literature of mediastinal parathyroid adenoma in MEN1 patient visualized by Tc-99m sestamibi SPECT/CT.

X-linked adrenoleukodystrophy (X-ALD) is a rare peroxisomal disorder, that is rapidly progressive, neurodegenerative, and recessive, and characteristically primary affects the central nervous system white matter and the adrenal cortex. X-ALD is diagnosed basaed on clinical, radiological, and serological parameters, including elevated plasma levels of very long chain fatty acids (VLCFA), such as C24:0 and C26:0, and high C24:0/C22:0 and C26:0/C22:0 ratios. These tests are complemented with genetic analyses. A 7.5-year-old boy was admitted to Department of Pediatrics, Chungnam National University Hospital with progressive weakness of the bilateral lower extremities. Brain magnetic resonance imaging confirmed clinically suspected ALD. A low dose adrenocorticotropic hormone stimulation test revealed parital adrenal insufficiency. His fasting plasma levels of VLCFA showed that his C24:0/C22:0 and C26:0/C22:0 ratios were significantly elevated to 1.609 (normal, 0-1.390) and 0.075 (normal, 0-0.023), respectively. Genomic DNA was extracted from peripheral whole blood samples collected from the patient and his family. All exons of ABCD1 gene were amplified by polymerase chain reaction (PCR) using specific primers. Amplified PCR products were sequenced using the same primer pairs according to the manufacturer's instructions. We identified a missense mutation (p.Arg163Leu) in the ABCD1 gene of the proband caused by the nucleotide change 488G>T in exon 1. His asymptomatic mother carried the same mutation. We have reported an unpublished mutation in the ABCD1 gene in a patient with X-ALD, who showed increased ratio of C24:0/C22:0 and C26:0/C22:0, despite a normal VLCFA concentrations.

OBJECTIVE: To investigate the effect of mirror therapy containing functional tasks on upper extremity function and activities of daily living in patients with subacute stroke. METHODS: The subjects were randomly divided into two groups: the mirror therapy group (30 patients) and the sham therapy group (30 patients). The mirror therapy group underwent a mirror therapy program together with conventional therapy for 20 minutes per day on 5 days per week for 4 weeks. The control group received a sham conventional therapy program under the same schedule as the mirror therapy group. The Fugl-Meyer Motor Function Assessment (FMA), Brunnstrom motor recovery stage, and Modified Barthel Index (MBI) were evaluated 4 weeks after the treatment. RESULTS: The upper extremity function on the affected side and ability to perform daily life activities after the intervention were significantly improved in both groups. After 4 weeks of intervention, improvements in the FMA (p=0.027) and MBI (p=0.041) were significantly greater in the mirror therapy group than the sham therapy group. CONCLUSION: In this study, we found that the mirror therapy containing functional task was effective in terms of improving the upper extremity functions and activities of daily living in patients with subacute stroke.
