ABSTRACT
The occurrence of an adenocarcinoma arising from a rectal diverticulum that causes mechanical ileus is very rare. Recently, we diagnosed a case of a mucinous adenocarcinoma in a rectal diverticulum after an emergent abdominal perineal resection and permanent colostomy by laparotomy. Here, we present a case report and a review of the literature.

An influenza pandemic due to a novel influenza A/H1N1 virus occurred after April 2009. This virus has some characteristics that differentiate it from the seasonal influenza virus. The 2009 pandemic influenza A/H1N1 virus can frequently infect the lower respiratory tract, and it might cause acute tracheobronchitis as well as pneumonia. Viral-bacterial interaction is well known as an important mechanism of the pathogenesis of respiratory complications of influenza. Herein, we report on a case that presented with pseudomembranous tracheobronchitis complicated by coinfection with 2009 pandemic influenza A/H1N1 and Staphylococcus aureus. We also review the relevent literature.

Cinnabar is the mineral with mercury in combination with sulfur, and it has been used to make charms in China and Korea. If cinnabar is overheated, mercury vapor that is extremely hazardous or sometimes fatal can be released. We experienced 5 patients of a family who were exposed to mercury vapor when they burnt charms. One of them developed severe acute respiratory failure and the patient needed mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Despite treatment with cortiocosteroid, D-penicillamine, ECMO and plasmapheresis, the radiologic findings of a patient worsened and he died.

BACKGROUND: In previous study, most patients with bronchial anthracofibrosis (BAF) were non-miners, and non-occupational old aged females. However, the clinical significance of BAF in patients with coal workers' pneumoconiosis (CWP) is unknown. METHODS: Among patients with CWP who transferred to our hospital for an evaluation of associated pulmonary diseases, 32 patients who had undergone a bronchofibroscopy (BFS) and chest computed tomography (CT) examination were evaluated for the association of the BAF using a retrospective chart review. RESULTS: Nine of the 32 CWP patients (28%) were complicated with BAF. Four of the 16 simple CWP patients (25%) were complicated with BAF. According to the International Labor Organization (ILO) classification by profusion, 2 out of 3 patients in category 1, 1 out of 8 patients in category 2 and 1 out of 3 patients in category 3 were complicated with BAF. Five out of 16 complicated CWP patients were complicated with BAF. Three out of 7 patients in type A and 2 out of 5 patients in type C were complicated with BAF. CWP patients with BAF had significantly greater multiple bronchial thickening and multiple mediastinal or hilar lymph node enlargement than the CWP patients without BAF. There was no difference in the other clinical features between the CWP patients with BAF and those without BAF. CONCLUSION: Many CWP patients were complicated with BAF. The occurrence of BAF was not associated with the severity of CWP progression. Therefore, a careful evaluation of the airway with a bronchoscopy examination and chest CT is warranted for BAF complicated CWP patients who present with respiratory symptoms and signs, even ILO class category 1 simple CWP patients.
