Outcomes and prognostic factors for severe community-acquired pneumonia that requires mechanical ventilation.
Community-acquired pneumonia (CAP) remains a common and serious condition worldwide. The mortality from severe CAP remains high, and this has reached 50% in some series. This study was conducted to determine the mortality and predictors that contribute to in-hospital mortality for patients who exhibit CAP and acute respiratory failure that requires mechanical ventilation. ⋯ Acute respiratory failure caused by severe CAP and that necessitates mechanical ventilation is associated with a high mortality rate. Initial hypercapnia and a large urine output favored survival, whereas a high APACHE II score predicted mortality.

Case ReportsA case of infected biloma due to spontaneous intrahepatic biliary rupture.
A "biloma" is a loculated collection of bile located outside of the biliary tree. It can be caused by traumatic, iatrogenic or spontaneous rupture of the biliary tree. Prior reports have documented an association of biloma with abdominal trauma, surgery and other primary causes, but spontaneous bile leakage has rarely been reported. ⋯ We recently diagnosed a spontaneous infected biloma by abdominal computed tomography and sonographically guided percutaneous aspiration. The patient was successfully managed with percutaneous drainage and intravenous antibiotics. We report here a case of infected biloma caused by spontaneous rupture of the intrahepatic duct, and review the relevant medical literature.

Reversible thermal injury to the esophagus as the result of drinking hot liquids has been reported to generate alternating white and red linear mucosal bands, somewhat reminiscent of a candy cane. This phenomenon is associated with chest pain, dysphagia, odynophagia, and epigastric pain. Here, we report a case of thermal injury to the esophageal and oral cavity due to the drinking of hot tea, including odynophagia and dysphagia. ⋯ The stomach and duodenum appeared normal. We diagnosed the patient with thermal esophageal injury inflicted by the hot tea. He was treated with pantoprazole, 40 mg/day, for 14 days, and evidenced significant clinical and endoscopic improvement.

Case ReportsPneumatosis intestinalis with pneumoperitoneum mimicking intestinal perforation in a patient with myelodysplastic syndrome after hematopoietic stem cell transplantation.
Pneumatosis intestinalis (PI) is an uncommon disorder characterized by an accumulation of gas in the bowel wall, and has been associated with a variety of disorders and procedures. We describe a 35-year-old man who undertook hematopoietic stem cell transplantation due to myelodysplastic syndrome. An abdominal X-ray demonstrated extensive PI with pneumoperitoneum mimicking hollow organ perforation. ⋯ Of the many factors that affect the gastrointestinal tract mucosal integrity, intramural pressure, and bacterial flora-produced intraluminal gas interact to produce PI. If the condition is accompanied by bowel ischemia, portomesenteric venous gas, metabolic acidosis, and abdominal sepsis, or if PI is severe in extent immediate surgical intervention is indicated. The described case supports that a mechanical rather than a bacterial etiology underlies the pathogenesis of PI.

Case ReportsUse of tadalafil for treating pulmonary arterial hypertension secondary to chronic obstructive pulmonary disease.
Pulmonary arterial hypertension (PAH) secondary to chronic obstructive pulmonary disease (COPD) is incurable and it has an unpredictable survival rate. Two men who suffered from COPD presented with progressive dyspnea and edema, respectively. PAH, as estimated by the peak velocity of tricuspidal regurgitation, and the depressed myocardial performance index (MPI) of the right ventricle (RV) were noted on echocardiography. ⋯ After 4 weeks of tadalafil treatment, the patients' pulmonary arterial pressure was decreased and the MPI of the RV was improved in both. The exercise capacity, as measured by the respiratory oxygen uptake, also improved from 10.9 mL/kg/min to 13.8 mL/kg/min in one patient. We report here on 2 patients with PAH secondary to COPD, and they showed notable improvement of their pulmonary hemodynamics and exercise capacity with the administration of tadalafil.
