A 74-year-old woman presented to our hospital with complaints of dysphagia. On examination, we diagnosed extensive thoracic aortic aneurysm and esophageal compression due to a descending thoracic aortic aneurysm. We planned a two-stage approach for repairing the extensive thoracic aortic aneurysm ; the first stage involving the repair of the ascending and arch segments, and the second stage involving the repair of the descending aorta. In the first stage, we performed the Bentall procedure and total arch replacement with a long elephant trunk. Following this, her dysphagia resolved, although the size of the descending aortic aneurysm was the same as that before the procedure (49 mm in diameter). We decided to treat her conservatively in the outpatient clinic without the second stage, because the descending aorta was asymptomatic and not sufficiently large. One year later, she presented with a sudden recurrence of dysphagia and swelling of buttocks. She was diagnosed with an expansion of the descending aortic aneurysm (62 mm in diameter) and a hematoma in the gluteal muscle due to aneurysm-induced disseminated intravascular coagulation (DIC). After emergency admission, she underwent a successful thoracic endovascular aortic repair and was discharged following a smooth recovery from dysphagia and aneurysm-induced DIC. We report this case along with a review of the literature.

Cyclin D1 gene (CCND1) numerical aberrations are independent prognostic indicators of head and neck squamous cell carcinomas (HNSCCs). High epidermal growth factor receptor gene (EGFR) copy number is associated with poor prognosis in lung cancer, but such findings are controversial in oral SCCs (OSCCs). We analyzed copy number status in CCND1 and EGFR in OSCC patients and its association with clinical outcome.EGFR and CCND1 statuses were analyzed in 85 OSCC patients by fluorescence in situ hybridization (FISH) of specimens obtained by fine-needle aspiration biopsy.CCND1 numerical aberration was found in 35 of 85 tumors (41%), and aberrant EGFR copy number was observed in 36 (42%). Gene amplification (GA) was dominant among CCND1 copy number changes (14/35:40%). Balanced trisomy (BT) was the most frequently observed EGFR aberration (17/36:47%). In a multivariate Cox's proportional hazards analysis, CCND1 GA was correlated with disease-free survival (P<0.001), whereas EGFR BT was significantly correlated with overall survival (P=0.001). Patients with a combination of CCND1 GA and/or EGFR BT had significantly poorer clinical outcome.CCND1 and EGFR copy number changes were frequent in OSCC and had differing aberration patterns. CCND1 GA and EGFR BT statuses by dual-color FISH were the predominant predictors of clinical outcome. Further investigation is needed to determine the implications for EGFR inhibitor therapy in OSCC.

The patch test is the most reliable method for diagnosing a metal allergy. However, interpretation of patch test results depends on the experience of the investigator and on the conditions of the individual patient. In the case of patch tests for metal salts, irritant reactions such as pustular or follicular reactions are quite common. Therefore, one must be careful not to interpret irritant reactions as allergic responses, and objective standards to evaluate erythema in patch tests need to be established.In the present study, we attempted to objectively evaluate patch test results for metal salts using an erythema index meter. We used the Erythema Index Difference (EID) (patch test site erythema index (EI) minus the mean EI of healthy skin outside the patch test area and at the unit tape site) rather than the EI itself in order to eliminate the effects of the patch test unit and individual differences. We measured the EID over time in patients with suspected metal allergies to various metals. Significant differences in EID were observed among ++ assessments, + assessments and irritant reactions based on International Contact Dermatitis Research Group (ICDRG) standards. In considering changes in EID over time, allergic and irritant reactions can be discriminated with high sensitivity (73.3%) and specificity (91.2%).These results suggest that the measurement of erythema over time with an erythema index meter is useful for the objective assessment of metal patch test reactions.
