Case Reports
Air leak syndrome as one of the manifestations of bronchiolitis obliterans organizing pneumonia.
A 46-year-old man developed respiratory distress with air leak syndrome (ALS), including pneumothorax, pneumomediastinum, and subcutaneous emphysema. Open lung biopsy was performed and revealed the histopathologic evidence of bronchiolitis obliterans organizing pneumonia (BOOP), which responded well to steroid treatment. As far as we know, this appears to be the first case of BOOP presenting with ALS as one of its major complications.

A 45-year-old Japanese man was referred to our hospital because of hyperglycemia despite the administration of as much as 120 U/day of human insulin. He had no history of injecting animal insulin. ⋯ He was successfully treated by cessation of insulin administration. A Scatchard analysis series showed that a reduction in the insulin binding capacity of antibodies paralleled the improvement in glycemic control.

Case Reports
Nosocomial pneumonia likely caused by Stenotrophomonas maltophilia in two patients with polymyositis.
We report two cases of polymyositis (PM) complicated with nosocomial pneumonia probably caused by Stenotrophomonas maltophilia, which was resistant to multiple antimicrobials. In the first case, the chest CT findings and high serum endotoxin level as well as sputum culture results were helpful for the proper diagnosis and the therapy was successful. However the second patient died of a lung abscess in spite of the intensive antibiotic therapy. When PM patients develop pneumonia unresponsive to various antibiotics, a multi-drug-resistant bacteria such as Stenotrophomonas maltophilia should be considered as the pathogen.

A 59-year-old woman was hospitalized in hypoglycemic coma. Although hypoglycemia was promptly reversed, she was in a somnolent, restless state with tachycardia, tremor, profuse sweating, and high body temperature. Thyrotoxic storm was highly suspected and vigorous antithyroid regimens gradually brought her up to normal mental and cardiovascular states in several days. ⋯ One month later, an episode of angina pectoris was followed by generalized convulsion, coma, and death in a few days. Neuroimaging study disclosed posterior leukoencephalopathy syndrome. This case is instructive in that hypoglycemic coma may masquerade the major symptomatology of thyrotoxic storm, and that profound myopathy and angiopathic or angiospastic processes of the brain and the heart may interfere with the outcome.

A 69-year-old male diabetic patient had an abnormally low HbA1C value of 2.8%, which was inconsistent with his elevated fasting plasma glucose of 8.2 mmol/l. Hb analysis disclosed that the abnormal Hb was Hb Ube-2 [alpha68 (E17) Asn --> Asp] and it accounted for 21.5% of the total Hb. Since the glycated abnormal Hb emerged at the same position as did HbF on high performance liquid chromatography, the HbA1C value was falsely low. The present case demonstrates that Hb Ube-2 is one of the abnormal Hbs in which caution should be exercised when monitoring diabetic control.
