Balloon-tipped, flow-directed (Swan-Ganz) catheters are used commonly for monitoring of cardiac function in patients undergoing cardiac surgical procedures. We report a case of pulmonary hypertension with hypoxemia which may be caused by incorrect positioning of pulmonary artery catheter (PAC) during CABG. Pulmonary arterial pressure (PAP) of 70/40 mmHg which was nearly high as systemic pressure was measured when we tried to wean patient from cardiopulmonary bypass. But, TEE (transesophageal echocardiography) showed nonspecific finding. PAP decreased soon and maintained about 33/16 mmHg for a few minutes. But, the PAP elevated high to 70/40 mmHg again and the arteral oxygen tension (PaO2) decreased to 61.2 mmHg. When we withdrew the PAC to the depth of 35 cm, the PAP and systolic pressure returned to normal range and PaO2 elevaed to 320 mmHg. End tidal CO2 was elevated from 30 mmHg to 35 mmHg.

Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.

PURPOSE: This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. MATERIALS AND METHODS: CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by CaldwelI-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. RESULTS: The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesions involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1- and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. CONCLUSION: Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during the previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocete and each compartment may show different signal intensities on MR.

PURPOSE: Thoracic ultrasonography (US) is an emerging tool for diagnosing pneumothorax (PTX), and the possible application of color Doppler to ultrasonography is another new development. The aim of this study is to analyze the possible contribution of color Doppler to thoracic US and to the estimation of pneumothorax volume. METHODS: Patients who were admitted to emergency department underwent chest X-ray and thoracic US with color Doppler. They were also evaluated by computed tomography, if needed, US was performed at four chest sites by emergency medicine faculty and resident, and concordance between color Doppler and lung sliding was analyzed. The number of sites with abnormal findings was correlated with the volume of PTX at each sites. Statistical analysis was performed with Pearson correlation. RESULTS: Sixty-three of 151 PTX cases were included in our study. The sensitivity of US was for PTX detection was 92.1% (58 of 63), and the concordance between color Doppler and lung sliding was 99.4%. The number of sites per patient with abnormal findings increased with the average volume of the PTX. The average PTX volume in the 5 cases with normal findings was 7.0%, which is a smallsized PTX. CONCLUSION: The use of color Doppler is not more accurate than lung sliding, but it may helpful in diagnosing PTX. The volume of a PTX is proportional to a patient's number of sites with abnormal US findings.

BACKGROUND: Homelessness is associated with an increased risk of exposure to Mycobacterium tuberculosis. Several factors, including alcoholism, malnutrition, lack of stable housing, combine to make tuberculosis more prevalent in the homeless. The aims of this study were to determine the factors associated with increasing success rate of tuberculosis treatment in the homeless. METHODS: A cross-sectional analysis of the clinical features in 142 pulmonary tuberculosis-positive homeless patients admitted to the Busan Medical Center from January 2001 to December 2010 was carried out. These results were compared with a successful treatment group and incomplete treatment group. We also evaluated the risk factors of treatment non-completion. Statistical analysis for the comparisons was performed using a chi2 test, independent samples t-test, and multiple logistic regression. RESULTS: Comparison of clinical characteristics showed significant differences between the two groups in the type of residence (P < 0.001), diseases with risk factors (P = 0.003), and history of tuberculosis treatment (P = 0.009). Multiple regression analysis revealed the residence (odds ratio [OR], 4.77; 95% confidence interval [CI], 2.05 to 11.10; P < 0.001) and comorbidity with risk factor (OR, 2.72; 95% CI, 1.13 to 6.53; P = 0.025) to be independently associated with treatment success. CONCLUSION: To improve the success rate of tuberculosis treatment in the homeless person, anti tuberculosis medication should be taken until the end of treatment and a management system for the homeless person is required. Further social and medical concerns for stable housing and management of comorbidity may lead to an improvement in the successful tuberculosis treatment of homeless person.
