Cross-sectional study on relationship between constipation and medication in consideration of sleep disorder.

Constipation can be caused by adverse drug reactions as a result of many drugs and might be induced by sleep disorders; however, the relative risk of its occurrence with individual drugs and the influence of sleep conditions have not been clarified. To clarify the relationship between constipation and various drugs in consideration of sleep disorders, we investigated the self-reported bowel habits, use of laxatives, and the Athens Insomnia Scale (AIS, a self-administered psychometric instrument to measure insomnia) in 344 inpatients on admission. They were divided into a constipation group (self-reported bowel habits of "Constipation" or "Occasional constipation" and/or use of laxatives, n=161) and a non-constipation group (both "Normal" and the non-use of laxatives, n=183).

Case-controlled study on risk factors for the development of constipation in hospitalized patients.

Constipation is a common problem in hospitalized patients; however, the relative risks of its development with various factors have not been clarified. To clarify the risk factors associated with constipation, we performed a case-controlled study of 165 hospitalized patients who were not laxative users on admission. They were divided into case (n=35) and control (n=130) groups according to laxative administration during hospitalization.

Mycobacterium avium pleuritis in a non-immunocompromised patient.

Nontuberculous mycobacterium infection is rarely accompanied by pleural involvement. We describe a very rare occurrence of Mycobacterium (M) avium pleuritis with pleural effusion in a non-compromised 73-year-old woman patient who had been treated for sick sinus syndrome. She was admitted to our hospital with general malaise and left pleural effusion.

Rapidly progressive interstitial pneumonia associated with clinically amyopathic dermatomyositis successfully treated with polymyxin B-immobilized fiber column hemoperfusion.

Amyopathic dermatomyositis (ADM) is a clinical subtype of dermatomyositis, characterized by the absence of motor weakness and the presence of normal muscle enzyme levels. ADM is sometimes accompanied by interstitial pneumonia that shows a rapid progressive course associated with a poor prognosis. We describe a 70-year-old man who presented rapidly progressive interstitial pneumonia associated with clinically ADM (C-ADM); he was successfully treated with polymyxin B-immobilized fiber column (PMX) hemoperfusion.
