In the management of advanced maxillary sinus cancer, sometimes it requires an extensive ablation and orbital exenteration that results in large and full defects of the cheek and orbital regions. Reconstruction of large orbital-maxillary defects can be accomplished in one stage by microsurgical free transfer of rectus abdominis myocutaneous flap. The muscle component is suitable to fill the orbital and maxillary cavities, and the skin components are used for cheek, palate and lateral nasal cavity wall reconstruction as a three-dimentional folded free flap. Major problems with this flap are the bulkiness, the possibility of abdominal hernia and muscle weakness following the removal of the rectus abdominis muscle. Free deep inferior epigastric artery skin flap without rectus abdominis muscle is available in the reconstruction of large orbital-maxillary defect without the problems of the rectus abdominis myocutaneous free flap. We experienced one case of rectus abdominis myocutaneous free flap, and one other case of inferior rectus abdominis free flap for the reconstruction of huge surgical defects due to radical maxillectomy with orbital excenteration. Both of the patients were satisfied and there have been no severe complication associated with these technique.

PURPOSE: This study was performed to compare the accuracy of noncontrast helical computerized tomography (NHCT) with that of intravenous pyelography (IVP) in the evaluation of urolithiasis in the emergency room (ER). METHODS: Between November 2003 and February 2004, a total of 47 consecutive patients presenting to the emergency department with acute flank pain were evaluated with NHCT followed by IVP. The mean of the time interval between NHCT and IVP was less than 5 minutes. All 47 sets of evaluations were later assessed randomly by an independent consulting radiologist for the presence, size, and location of a stone, ureteral dilatation, and secondary signs of ureteral obstruction. RESULTS: Forty-three of the 47 patients were diagnosed with urolithiasis. In 39 of the 43 patients diagnosed with ureteral calculi, the NHCT made the diagnosis. IVP made the diagnosis in 26 of the 43 patients. NHCT had a 90.7% sensitivity, 100% specificity, and 68% accuracy. Compared with IVP, using the McNemar test, NHCT was significantly better able to predict the presence of urolithiasis (p<0.001). CONCLUSIONS: Unnenhanced helical CT is superior to IVP in the demonstration of ureteral calculi in patients with suspected acute urolithiasis in the ER.

A 38-year-old man visited our emergency department presenting with a 6-day persistent fever. The man had undergone an orthodontic procedure 7 days prior to the visit. He had a fever with a temperature of 38.2degrees C and a diastolic murmur (grade III) was detected at the left sternal border. Reddish-brown lines beneath the nails were present, and raised lesions which were red and painful were detected on the soles of the patient's feet. Laboratory findings showed an elevated inflammatory marker. Transthoracic and transesophageal echocardiograms, showed a bicuspid aortic valve, and moderate aortic regurgitation and vegetation were noted. Treatment with antibiotics was given, but 4 days later, a 12 lead electrocardiogram revealed complete atrioventricular (AV) block. Immediately, a temporary pacemaker was inserted, and the following day an aortic valve replacement was performed. Intraoperative findings revealed a fistula around the AV node. He has suffered no subsequent cardiac events during the follow-up.

BACKGROUND/AIMS: The modified early warning score (MEWS) is used to predict patient intensive care unit (ICU) admission and mortality. Lactate (LA) in the blood lactate (BLA) is measured to evaluate disease severity and treatment efficacy in patients with severe sepsis/septic shock. The usefulness of a combination of MEWS and BLA to predict ICU transfer in severe sepsis/septic shock patients is unclear. We evaluated whether use of a combination of MEWS and BLA enhances prediction of ICU transfer and mortality in hospitalized patients with severe sepsis/septic shock. METHODS: Patients with severe sepsis/septic shock who were screened or contacted by a medical emergency team between January 2012 and August 2012 were enrolled at a university-affiliated hospital with ~2,700 beds, including 28 medical ICU beds. RESULTS: One hundred patients were enrolled and the rate of ICU admittance was 38%. MEWS (7.37 vs. 4.85) and BLA concentration (5 mmol/L vs. 2.19 mmol/L) were significantly higher in patients transferred to ICU than those in patients treated in general wards. The combination of MEWS and BLA was more accurate than MEWS alone in terms of ICU transfer (C-statistics: 0.898 vs. 0.816, p = 0.019). The 28-day mortality rate was 19%. MEWS was the only factor significantly associated with 28-day mortality rate (odds ratio, 1.462; 95% confidence interval, 1.122 to 1.905; p = 0.005). CONCLUSIONS: The combination of MEWS and BLA may enhance prediction of ICU transfer in patients with severe sepsis/septic shock.

The heart and the brain, most oxygen-dependent organs, may be severely affected after carbon monoxide (CO) exposure. CO induced cardiotoxicity may occur as a consequence of moderate to severe CO poisoning, including angina attack, myocardial infarct, arrhythmias, and heart failure. We present a rare case of CO poisoning induced cardiomyopathy with left ventricular (LV) thrombus. It is thought that LV thrombus may have been caused severely decreased LV function with dyskinesis. After short-term anticoagulant therapy, echocardiography findings revealed complete recovery of LV dyskinesis and resolution of LV thrombus.

BACKGROUND/AIMS: Hepatitis-B-related acute-on-chronic liver failure has a poor prognosis. However, the advent of potent oral antiviral agents means that some patients can now recover with medical treatment. We aimed to identify the prognostic factors for hepatitis-B-related acute-on-chronic liver failure including the initial as well as the dynamically changing clinical parameters during admission. METHODS: Sixty-seven patients were retrospectively enrolled from 2003 to 2012 at Samsung Medical Center. The patients were classified into three categories: Recovery group (n=23), Liver transplantation group (n=28), and Death group (n=16). The Liver transplantation and Death groups were combined into an Unfavorable prognosis group. We analyzed the prognostic factors including the Model for End-Stage Liver Disease (MELD) scores determined at 3-day intervals. RESULTS: A multivariable analysis showed that the unfavorable prognostic factors were a high initial MELD score (> or =28) (odds ratio [OR] =6.64, p=0.015), moderate-to-severe ascites at admission (OR=6.71, P=0.012), and the aggravation of hepatic encephalopathy during hospitalization (> or =grade III) (OR=15.41, P=0.013). Compared with the baseline level, significant reductions in the MELD scores were observed on the 7th day after admission in the Recovery group (P=0.016). CONCLUSIONS: Dynamic changes in clinical parameters during admission are useful prognostic factors for hepatitis-B-related acute-on-chronic liver failure.
