BACKGROUND: Unplanned extubation (UE) of patients requiring mechanical ventilation in an intensive care unit (ICU) is associated with poor outcomes for patients and organizations. This study was conducted to assess the clinical features of patients who experienced UE and to determine the risk factors affecting reintubation after UE in an ICU. METHODS: Among all adult patients admitted to the ICU in our institution who required mechanical ventilation between January 2011 and December 2013, those in whom UE was noted were included in the study. Data were categorized according to noninvasive or invasive management after UE. RESULTS: The rate of UE was 0.78% (the number of UEs per 100 days of mechanical ventilation). The incidence of self-extubation was 97.2%, while extubation was accidental in the remaining patients. Two cases of cardiac arrest combined with respiratory arrest after UE were noted. Of the 214 incidents, 54.7% required invasive management after UE. Long duration of mechanical ventilation (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.32-1.75; p = 0.000) and high ICU mortality (OR 4.39; 95% CI 1.33-14.50; p = 0.015) showed the most significant association with invasive management after UE. In multivariate analysis, younger age (OR 0.96; 95% CI 0.93-0.99; p = 0.005), medical patients (OR 4.36; 95% CI 1.95-9.75; p = 0.000), use of sedative medication (OR 4.95; 95% CI 1.97-12.41; p = 0.001), large amount of secretion (OR 2.66; 95% CI 1.01-7.02; p = 0.049), and low PaO2/FiO2 ratio (OR 0.99; 95% CI 0.98-0.99; p = 0.000) were independent risk factors of invasive management after UE. CONCLUSIONS: To prevent unfavorable clinical outcomes, close attention and proper ventilatory support are required for patients with risk factors who require invasive management after UE.

The estimated incidence of duodenal Crohn,s disease ranges from 0.5-4% of the patients with Crohn,s disease. However, isolated involvement of Crohn,s disease in the duodenum is very rare, and most duodenal Crohn's disease is accompanied with it elsewhere in the gastrointestinal tract. As clinical, radiographic, and endoscopic features may overlap with those of peptic ulcer disease, patients presenting with isolated duodenal involvement may be perplexing diagnostically. The initial treatment for duodenal Crohn,s diease is medical, but if complications such as gastric outlet obstrution, intractable pain during medical therapy, or hemorrhage occur, surgical intervention is necessary. We experienced one case of isolated duodenal Crohn,s disease showing gastric outlet obstruction without any lesion elsewhere in the gastrointestinal tract and report the case with a review of the literature.

Conventional medical therapies have not been very successful in treating adults with refractory septic shock. The effects of direct hemoperfusion using polymyxin B and veno-arterial extracorporeal membrane oxygenation (ECMO) for refractory septic shock remain uncertain. A 66-year-old man was admitted to the emergency department and suffered from sepsis-induced hemodynamic collapse. For hemodynamic improvement, we performed direct hemoperfusion using polymyxin B. Computed tomography scan of this patient revealed emphysematous pyelonephritis (EPN), for which he underwent emergent nephrectomy with veno-arterial ECMO support. To the best of our knowledge, this is the first report of successful treatment of EPN with refractory septic shock using polymyxin B hemoperfusion and nephrectomy under the support of ECMO.

Small hepatoma is defined as hepatocellular carcinoma less than 3cm in maximum diameter and fewer than 3 innumber. To assess the ability of ultrasound to detect small hepatomas, a prospectively study was done in a groupof patients with HBsAg-positive chronic hepatitis and liver cirrhosis. Herein, we present 4 hypoechoic smallhepatomas detected on ultrasound and emphasize the role of real-time ultrasonography as a practical test formonitoring hepatoma high-risk, subjects.

Mucormycosis is an uncommon opportunistic fungal infection mostly affecting immunocompromised patients and gastrointestinal mucormycosis is a rare and life-threatening. We describe a 31-year-old man with a history of idiopathic cyclic neutropenia who developed perforations of the stomach and intestine and intra-abdominal bleeding due to disseminated gastrointestinal mucormycosis after the initial operation.

The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of 500 mL of blood within 24 hours. A pan-systolic murmur was found on chest examination. A chest computed tomography showed airspace consolidation in the right upper and middle lobes, with faint bilateral ground glass opacity. Echocardiography revealed mitral valve prolapse and grade IV mitral regurgitation. The patient was diagnosed with sporadic primary mitral valve prolapse. After mitral valve repair surgery, the patient recovered fully.
