A 49-year-old man, who had a 30-year history of drinking the equivalent of 80 g of ethanol per day, underwent a detailed medical examination for cough and dyspnea. Chest-abdominal computed tomography and endoscopic retrograde pancreatography led to the diagnosis of a mediastinal pancreatic pseudocyst resulting from obstruction of the pancreatic duct by a protein plug. The pseudocyst rapidly improved with conservative treatment with camostat mesilate, H2-receptor antagonist and digestive enzymes. Although the patient abstained from alcohol for approximately 6 months, he resumed drinking, leading to recurrent attacks of pancreatitis. Bromhexine hydrochloride was then administered for 6 months, with the expectation that it would have a mucolytic effect on the pancreatic juice, resulting in improvement in the clinical symptoms, pancreatic enzymes and pancreatic exocrine function, as well as elimination of the protein plug. Bromhexine hydrochloride may be a new therapy for pathological states, such as alcoholic chronic pancreatitis, in which there is increased viscosity of the pancreatic juice because of elevated protein concentration, leading to protein plug formation and temporary blockage of the pancreatic duct.

The clinical symptoms of colonic tuberculosis are variable, among which massive melena is extremely rare. Herein, we report two cases of colonic tuberculosis representing with massive melena, both of whom never had active pulmonary tuberculosis. The first case was a 55-year-old woman. Although her emergency colonoscopic setting suggested colonic tuberculosis, no evidence of tuberculosis could be found at that time. We performed a therapeutic trial and observed a drastic regression of the initial changes with 4-week treatment using antituberculous agents. The second case was a 37-year-old man. His emergency colonoscopy showed lesions mimicking colon carcinoma. However, the histological examinations did not indicate malignancy. The polymerase chain reaction of colonic biopsy specimen was positive for Mycobacterium tuberculosis. Similar to the first case, a significant improvement of the initial lesions was observed after 4-week treatment using antituberculous agents. Collectively, although the massive melena is a rare manifestation, tuberculosis of the colon should be suspected in the patients with such symptom.

Bromhexine hydrochloride may be a new for the morbidity of chronic pancreatitis, in which there is increased viscosity of the pancreatic juice and formation of a protein plug.

Long-term lifestyle-based daily walking program prevented the age-related IMAT accumulation in middle-aged and elderly adults. Furthermore, increased daily walking correlated with decreased IMAT over 5 years.
