Terephthaloyl chloride, a chemical of low molecular weight, is used as an intermediate by a fabric manufacturing industry. It is known to cause gastrointestinal, respiratory and skin irritation. However, it has not been reported as a cause of occupational asthma till now. We report a case of occupational asthma caused by prolonged exposure to terephthaloyl chloride in the workplace. A 38 year-old man visited at the Allergy Clinic because of cough, dyspnea and wheezing for 5 years. He had worked at a factory for 15 years where he was involved in the process of manufacturing fabrics. At presentation, he had no symptoms and showed no abnormality on physical examination. When challenged with vapor of terephthaloyl chloride, he experienced sneezing and paroxysmal cough in a couple of minutes, followed by dyspnea and wheezing at 10 min. He also experienced urticarial rashes on the face and chest. The pulmonary function tests showed an atypical prolonged immediate airway response. PC20 methacholine decreased from 5 mg/ml to 0.79 mg/ml 24 hours after the challenge. Light microscopic examination of bronchial biopsies showed loss of epithelium, thickening of basement membrane, submucosal fibrosis, and increased inflammatory cell infiltration. The immediate drop in FEV1 and urticarial rash to terephthaloyl chloride suggests the possibility of an immediate hypersensitivity immune reaction. Further studies are needed to clarify the exact mechanism of terephthaloyl chloride induced asthma.

PURPOSE: The aim of this study is to know whether silibinin has an anticancer effect on triple negative breast cancer xenograft model using MDA-MB-468 cells. METHODS: To establish the xenograft model, we injected the MDA-MB-468 cells into female Balb/c-nude mice. After establishing a xenograft model, oral silibinin was administered to the tested mice in the way of 200 mg/kg for 45 days. The difference of mean tumor volume between silibinin fed mice and control mice was analyzed. The epidermal growth factor receptor (EGFR) phosphorylation in MDA-MB-468 cells was analyzed by Western blotting. The expression of VEGF, COX-2, and MMP-9 genes in tumor tissue was analyzed by real-time polymerase chain reaction (PCR). RESULTS: In the xenograft model using MDA-MB-468 cells, we found that oral administration of silibinin significantly suppressed the tumor volume (silibinin treated mice vs. control mice; 230.3 +/- 61.6 mm3 vs. 435.7 +/- 93.5 mm3, P < 0.001). The phosphorylation of EGFR in MDA-MB-468 cells was inhibited by treatment with 50 microg/mL of silibinin. In real time-PCR analysis of tumor tissue obtained from sacrificed mice, the gene expression of MMP-9, VEGF, and COX-2 was 51.8%-80% smaller in silibinin group than that of control group and we can also verify the similar result using Western blotting analysis. CONCLUSION: We verified that silibinin had anticancer effect on xenograft model of MDA-MB-468 cells in the way of preventing the phosphorylation of EGFR and eventually suppressed the production of COX-2, VEGF, and MMP-9 expression. Finally, the tumor volume of xenograft models was decreased after administration of Silibinin.

Immunoglobulin G4 (IgG4)-related disease (RD) is an immune-mediated, systemic fibroinflammatory condition characterized by a lymphoplasmacytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. IgG4-RD has become recognized with increasing frequency since the turn of the century and may affect almost any organ. IgG4-RD also involves the meninges but, to the best of our knowledge, no case of IgG4-related intracranial pachymeningitis with periaortitis has been reported in Korea to date. Here, we report on a 65 year-old male with IgG4-RD involving the meninges and aorta.

PURPOSE: The axillary arch is an anomalous muscle that is not infrequently encountered during axillary sentinel lymph node biopsy (SLNB) of breast cancer patients. In this study, we aimed to investigate how often the axillary arch is found during SLNB and whether it affects the intraoperative sentinel lymph node (SLN) identification rate. METHODS: We retrospectively analyzed the correlation between the presence of the axillary arch and the SLN sampling failure rate during SLNB in 1,069 patients who underwent axillary SLNB for invasive breast cancer. RESULTS: Of 1,069 patients who underwent SLNB, 79 patients (7.4%) had the axillary arch present. The SLNB failure rate was high when the patient's body mass index was > or =25 (p=0.026), when a single SLN mapping technique was used (p=0.012), and when the axillary arch was present (p<0.001). These three factors were also found to be statistically significant by multivariate analysis, and of these three factors, presence of the axillary arch most significantly increased the SLNB failure rate (hazard ratio, 10.96; 95% confidence interval, 4.42-27.21; p<0.001). Additionally, if the axillary arch was present, the mean operative time of SLNB was 20.8 minutes, compared to 12.5 minutes when the axillary arch was not present (p<0.001). If the axillary arch was present, the SLN was often located in a high axillary region (67%) rather than in a general low axillary location. CONCLUSION: The axillary arch was found to be a significant factor affecting intraoperative SLN failure rate. It is necessary to keep in mind that carefully checking the high axillar region during SLNB in breast cancer patients with the axillary arch is important for reducing SLN sampling failure.

PURPOSE: The result of embolization via an external superior ophthalmic vein approach of carotid cavernous sinus fistula was first described around 1970s. We report a case of coil embolization of carotid cavernous sinus fistula using a superior ophthalmic vein approach. METHODS: A 70-year-old female had a 3-month history of headache, periocular pain, and diplopia. Diagnostic orbital contrast-enhanced CT, brain MRI and contrast-angiography and cerebral angiography revealed a carotid cavernous sinus fistula. Fistula occlusion via transfemoral endovascular embolization failed, so we then tried coil embolization using an external superior ophthalmic vein approach of carotid cavernous sinus fistula. RESULTS: The coil embolization via an external superior ophthalmic vein approach was difficult because of venous tortuosity and poor exposure of part of orbital roof area. But, X-ray-guided direct puncture of the superior ophthalmic vein was successful. We thus had good results with coil embolization of carotid cavernous fistula. CONCLUSIONS: The coil embolization via superior ophthalmic vein approach is an effective and challengeable treatment when surgical cauterization or conventional endovascular embolization fails. We suggest that there is need to training ophthalmologists to be experienced in external orbital surgery.

PURPOSE: Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare disase, which causes chronic progressive inflammation and thickening of the basal dura mater. We report a case of IHCP associated with superior oblique paralysis and present a review of the literature. METHODS: An 8-year-old boy presented with binocular diplopia and left side head tilting. Suspecting right superior oblique muscle paralysis, an alternating prism test, head tilt test, fundus examinations, neurologic examination, and brain MRI were performed. RESULTS: The brain MRI revealed abnormal enhancement of the right tentorium in the course of the right fourth cranial nerve, leading to a diagnosis of IHCP with paralytic strabismus and the patient was treated with systemic steroid therapy. CONCLUSIONS: We report a case of IHCP with right superior oblique paralysis. Patients with recent onset paralytic strabismus require appropriate neurolgic and neuroimaging examinations.

OBJECTIVES: This study was performed to investigate the relationship between cell counts, supernatant and lysate ECP levels in sputum, and physiologic markers in adult asthmatics. METHODS: Twenty-two patients with mild to moderate persistent asthma, ten patients with acute exacerbated asthma and nine healthy subjects were enrolled. Sputum was induced by inhalation of hypertonic saline, and homogenized with 0.1% dithiothreitol. A total and differential cell was measured. The remnant cell suspension was centrifuged, and ECP (supernatant ECP) was measured in supernatant fluid. Cell pellet was reacted with a cellular lysis buffer to release cell-associated ECP, and ECP (lysate ECP) was measured again in supernatant fluid. The ratio of supernatant to lysate ECP was calculated as an index of eosinophil degranulation. Spirometry and methacholine bronchial challenge tests were also performed as physiological markers of asthma. RESULTS: The patients with acute exacerbated asthma showed significantly higher percentage of sputum neutrophil, eosinophil count, concentration of sputum supernatant ECP and ratio of supernatant to lysate ECP than those of normal controls and stable asthmatic patients(p < 0.05, respectively). The level of sputum supernatant ECP, supernatant/lysate ECP ratio, and percentage of neutrophil showed negative correlations with pulmonary functions, but no correlations with a degree of bronchial hyperresponsiveness. There was no significant correlations between of serum ECP level and physiological parameters. CONCLUSION: These results suggest that both neutrophils and eosinophils play roles in the exacerbation of asthma. The sputum supernatant/lysate ECP ratio might be valuable in assessment of activation status of eosinophils in various hypereosinophilic conditions or diseases.
