The population in Japan is aging at a faster rate than in other countries in the world. It is speculated that the number of patients with late-onset amyotrophic lateral sclerosis (ALS) will increase even more in the future. However, few studies have been undertaken on the characteristics of patients with late-onset ALS in Japan. This study sought to investigate the clinical features of patients with late-onset ALS compared with those with early-onset ALS using the progression rate (ΔFS). ⋯ Our finding suggested that patients with late-onset ALS showed more rapid disease progression than those with early-onset ALS using ΔFS.

Since serum albumin is glycosylated more rapidly than hemoglobin, it is possible that the glycated albumin (GA) to HbA1c ratio (GA: HbA1c ratio) is potentially a more sensitive indicator of blood glucose excursion than HbA1c. The aim of the present study was to assess the clinical usefulness of GA: HbA1c ratio as a marker of daily glucose excursions in patients with type 1 diabetes according to the subtypes; acute onset type 1A, fulminant and slowly progressive type 1 diabetes. ⋯ In conclusion, the present study demonstrated that GA: HbA1c ratio could be a better marker for glycemic variability than HbA1c in type 1 diabetes, especially in fulminant type 1 diabetes.

A 41-year-old man was diagnosed with a solitary fibrous tumor (SFT) of the pleura in the posterior mediastinum. Despite two surgeries for excision, the SFT recurred and progressed with direct invasion of the chest wall and bone metastases. ⋯ High-molecular-weight (HMW) insulin-like growth factor II (IGF-II) was identified in the serum and tumor using Western blotting and immunohistochemistry. These findings suggested that the cause of the recurrent severe hypoglycemia was SFT production of HMW IGF-II, a mediator of non-islet cell tumor-induced hypoglycemia (NICTH).

Raoultella ornithinolytica is a Gram-negative aerobic bacillus reclassified in the new genus from the Klebsiella species based on new genetic approaches; however, human infections caused by R. ornithinolytica are rare. We herein report three cases of R. ornithinolytica bacteremia associated with biliary tract infections in cancer patients. R. ornithinolytica can be a causative pathogen of biliary tract infection in cancer patients.

Case Reports
An elderly patient who developed spontaneous spinal epidural hematoma during warfarin therapy.
Spontaneous spinal epidural hematoma (SSEH) is an uncommon but clinically important disease, and delayed diagnosis of this condition can have severe consequences. General physicians should consider the possibility of SSEH when they encounter a patient with a sudden onset of unexplained cervical or back pain or subsequent radicular symptoms during anticoagulant therapy. Immediate magnetic resonance imaging is essential for early diagnosis. In this article, we present a rare case of an 80-year-old man who developed cervical SSEH during warfarin therapy.
