Review Case Reports
Acute-onset sarcoidosis with erythema nodosum and polyarthralgia (Löfgren's syndrome) in Japan: a case report and a review of the literature.
Löfgren's syndrome is an acute form of sarcoidosis that is characterized by erythema nodosum (EN), bilateral hilar lymphadenopathy (BHL), and polyarthralgia or polyarthritis. This syndrome is common among white people, but is considered rare among Japanese people. We present the case of a 26-year-old Japanese woman with Löfgren's syndrome. ⋯ Six Japanese cases of Löfgren's syndrome have been reported previously. Five of the seven Japanese patients with Löfgren's syndrome had normal ACE levels; all of them exhibited BHL. Löfgren's syndrome should be considered as a possibility when examining a patient with EN and articular symptoms, even if the patient is Japanese.

Practice Guideline
The JRS guidelines for the management of community-acquired pneumonia in adults: an update and new recommendations.
Community-acquired pneumonia (CAP) continues to be a major medical problem. Since CAP is a potentially fatal disease, early appropriate antibiotic treatment is vital. Epidemiologic studies have shown that in the combined cause-of-death category, pneumonia ranks fourth as the leading cause of death in Japan. ⋯ The basic policy and main purposes of the JRS guidelines include; 1) prevention of bacterial resistance and 2) effective and long-term use of medical resources. The JRS guidelines have recommended the exclusion of potential and broad spectrum antibiotics, fluoroquinolones and carbapenems, from the list of first-choice drugs for empirical treatment. In addition, the JRS guidelines have recommended short-term usage of antibiotics of an appropriate dose and pathogen-specific treatment using rapid diagnostic methods if possible.

We investigated the link between metabolic syndrome and proteinuria in Japanese. ⋯ The present study indicated that metabolic syndrome might be an important factor in the etiology of proteinuria in Japanese.
