Catamenial hemoptysis is a rare condition, characterized by recurrent hemoptysis associated with the presence of intrapulmonary or endobronchial endometrial tissue. Therapeutic strategies proposed for intrapulmonary endometriosis with catamenial hemoptysis consist of medical treatments and surgery. Bronchial artery embolization is a well-established modality in the management of massive or recurrent hemoptysis, but has seldom been used for the treatment of catamenial hemoptysis. We report a case of catamenial hemoptysis associated with pulmonary parenchymal endometriosis, which was successfully treated by a bronchial artery embolization.

BACKGROUND AND PURPOSE: Perfusion-diffusion mismatch has been evaluated to determine whether the presence of a target mismatch helps to identify patients who respond favorably to recanalization therapies. We compared the impact on infarct growth of collateral status and the presence of a penumbra, using magnetic resonance perfusion (MRP) techniques. METHODS: Consecutive patients who were candidates for recanalization therapy and underwent serial diffusion-weighted imaging (DWI) and MRP were enrolled. A collateral flow map derived from MRP source data was generated by automatic post-processing. The impact of a target mismatch (Tmax>6 s/apparent diffusion coefficient (ADC) volume≥1.8, ADC volume<70 mL; and Tmax>10 s for ADC volume<100 mL) on infarct growth was compared with MR-based collateral grading on day 7 DWI, using multivariate linear regression analysis. RESULTS: Among 73 patients, 55 (75%) showed a target mismatch, whereas collaterals were poor in 14 (19.2%), intermediate in 36 (49.3%), and good in 23 (31.5%) patients. After adjusting for initial severity of stroke, early recanalization (P<0.001) and the MR-based collateral grading (P=0.001), but not the presence of a target mismatch, were independently associated with infarct growth. Even in patients with a target mismatch and successful recanalization, the degree of infarct growth depended on the collateral status. Perfusion status at later Tmax time points (beyond the arterial phase) was more closely correlated with collateral status. CONCLUSIONS: Patients with good collaterals show a favorable outcome in terms of infarct growth, regardless of the presence of a target mismatch pattern. The presence of slow blood filling predicts collateral status and infarct growth.

BACKGROUND/AIMS: During endoscopic retrograde cholangiopancreatography (ERCP), all efforts should be made to be aware of radiation hazards and to reduce radiation exposure. The aim of this study was to investigate the status of radiation protective equipment and the awareness of radiation exposure in health care providers performing ERCP in Korean hospitals. METHODS: A survey with a total of 42 questions was sent to each respondent via mail or e-mail between October 2010 and March 2011. The survey targeted nurses and radiation technicians who participated in ERCP in secondary or tertiary referral centers. RESULTS: A total of 78 providers from 38 hospitals responded to the surveys (response rate, 52%). The preparation and actual utilization rates of protective equipment were 55.3% and 61.9% for lead shields, 100% and 98.7% for lead aprons, 47.4% and 37.8% for lead glasses, 97.4% and 94.7% for thyroid shields, and 57.7% and 68.9% for radiation dosimeters, respectively. The common reason for not wearing protective equipment was that the equipment was bothersome, according to 45.7% of the respondents. CONCLUSIONS: More protective equipment, such as lead shields and lead glasses, should be provided to health care providers involved in ERCP. In particular, the actual utilization rate for lead glasses was very low.

PURPOSE: This purpose of this study was to develop evidence-based practice guideline for isolation in health care settings to prevent transmission of infectious diseases utilizing guideline adaption process. METHODS: The process of guideline adaptation was performed according to the Korean hospital nurses association's guideline adaptation manual which consisted of three main phases, 9 modules, and 24 steps. RESULTS: The adapted isolation guideline consisted of introduction, overview of isolation guideline, summary of recommendations, recommendations, references, and appendices. The guideline includes 224 recommendations in 4 sections which are organizational administration, standard precautions, transmission-based precautions, and education/counselling. CONCLUSION: The adapted isolation guideline is recommended to be disseminated and utilized by nurses and clinicians nationwide to improve the isolation practices for infected or colonized patients with communicable diseases and to decrease the transmission of infections in the healthcare settings.

BACKGROUND: Small proportions of all the elderly stroke patients receive recombinant tissue plasminogen activator (r-tPA) therapy, although old age is not a proven contraindication to intravenous thrombolytic therapy for acute ischemic stroke. The purpose of this study was to identify reasons for exclusion from r-tPA therapy and factors associated with the decision of r-tPA use in elderly patients with acute ischemic stroke. METHODS: From the acute stroke registries of 22 domestic university hospitals taking the r-tPA therapy from January 2007 to May 2010, we extracted data of all acute ischemic stroke patients who were aged 80 or over and arrived within onset 3 hours. For all patients, we assessed the eligibility of r-tPA therapy using National Institute of Neurological Disorders and Stroke (NINDS) r-tPA trial criteria. For eligible patients, we compared all clinical variables between patients who were treated with r-tPA and those who were not, and analyzed potential factors related to the decision of r-tPA use. RESULTS: A total of 494 patients were included in this study. 255 patients (51.6%) were excluded by NINDS r-tPA trial criteria and the major reasons for exclusion were minor neurological deficit (53.7%) and clinical improvement (17.3%). Among 239 patients who were eligible for r-tPA, 162 (32.8%) patients received r-tPA and 77 (15.6%) did not. Multivariable analysis showed that younger age, shorter time-delay from onset to admission, non-smoker, no history of prior stroke, good pre-stroke functional status and severe initial neurological deficit were independently associated with the decision of r-tPA use in the elderly stroke patients predictors for r-tPA treatment. CONCLUSION: In very elderly patients, mild neurological deficit on arrival and rapid clinical improvement in neurological symptoms were the main reasons for exclusion from thrombolytic therapy.
