To assess longitudinal changes in the clinical features of patients with amyotrophic lateral sclerosis (ALS), we performed a retrospective hospital-based study covering 35 years. ⋯ Our findings demonstrate that, among patients with sporadic ALS, the age at disease onset, the proportion of patients with disease onset at 70 years of age or higher, the proportion of patients with dementia and the proportion of patients with bulbar onset ALS have increased significantly over the past 35 years. The longitudinal changes observed in the clinical features of ALS may reflect the increasing age at disease onset.

Case Reports
Pulmonary tumor thrombotic microangiopathy with circulatory failure treated with imatinib.
Pulmonary tumor thrombotic microangiopathy is a lethal, yet difficult to diagnose, complication of gastrointestinal carcinoma. Even if properly diagnosed, there is no treatment, especially after a circulatory collapse. ⋯ Pulmonary hypertension was dramatically ameliorated and the patient was able to be weaned from percutaneous cardiopulmonary support within 20 days of treatment. Imatinib may be effective for ameliorating pulmonary hypertension that is caused by pulmonary tumor thrombotic microangiopathy.

Shewanella bacteremia is an uncommon but potentially fatal disease. Although hepatobiliary diseases have been proposed to be risk factors for various Shewanella infections, little is known about the features of Shewanella bacteremia in patients with hepatobiliary diseases. This study aims to characterize the presentation and risk factors of Shewanella bacteremia in patients with hepatobiliary diseases. ⋯ It is recommended that the possibility for Shewanella infection be considered in patients with bacteremia and also underlying hepatobiliary diseases, particularly if patients present with hepatobiliary infections, a history of seafood, or development of the disease during the summer.

Klebsiella pneumonia usually causes urinary tract infections, pneumonia, and other infectious diseases in hospitalized and immunocompromised patients. Among the types of Klebsiella pneumonia, serotype K1 is known to be a highly virulent pathogen. ⋯ Although the patient received percutaneous abscess drainage and antibiotic therapy, he lost his eyesight. To improve the poor prognoses of ocular complications, providing both an earlier diagnosis and treatment is critical.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a unique, rare and fatal form of pulmonary arterial tumor embolism. The aim of this study was to evaluate the clinical characteristics and pathological and immunohistochemical findings of PTTM. ⋯ Clinicians should suspect PTTM in cancer patients who exhibit acute worsening respiratory insufficiency accompanied by a hypercoagulative state without embolism in major pulmonary arteries. The PTTM patients evaluated in our study had very poor prognoses. Vascular endothelial growth factor and tissue factor may play important roles in PTTM.
