Clinical Benefits of Oral Anticoagulants for Elderly Patients With Cardioembolic Stroke at High Bleeding Risk.

Background/aim: The relationship between the severity of cardioembolic stroke (CES) and oral anticoagulant (OAC) treatment before stroke onset in very elderly (≥80 years) patients with nonvalvular atrial fibrillation (NVAF) at high bleeding risk remains unknown.

Patients And Methods: A total of 364 consecutive patients (≥80 years) with CES and NVAF within 48 h following stroke onset were investigated. High bleeding risk was defined as follows: Bleeding history, renal dysfunction (creatinine clearance <30 ml/min), low body weight (≤45 kg), and antiplatelet or nonsteroidal anti-inflammatory drug use.

Low Creatinine Clearance Is a Risk Factor for Severe Cardioembolic Stroke in Japanese Female Patients.

Background/aim: The relationship between renal function and severity of cardioembolic stroke (CES) stratified by sex remains poorly understood.

Patients And Methods: A total of 640 consecutive CES patients within 48 h after stroke onset and with a modified Rankin Scale (mRS) score of 0 or 1 before onset were studied. The patients were divided into three groups based on their CCr values: low creatinine clearance (CCr) (L-CCr) (n=71, <30 ml/min), middle CCr (M-CCr) (n=227, 30 to <50 ml/min), and high CCr (H-CCr) (n=342, ≥50 ml/min).

Regression of Crizotinib-Associated Complex Cystic Lesions after Switching to Alectinib.

Crizotinib, which is effective in patients with anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer, is sometimes associated with the generation of complex renal cysts. A 56-year-old man with ALK positive adenocarcinoma received crizotinib. Ten months after the introduction of crizotinib, a cystic lesion developed from his right kidney to the iliopsoas muscle, accompanied by fever, anemia, and hypoproteinemia.

Dramatic response to alectinib in a patient of ALK-rearranged lung cancer with poor performance status.

Background: Lung cancers with anaplastic lymphoma kinase rearrangements are highly sensitive to anaplastic lymphoma kinase tyrosine kinase inhibition, underscoring the notion that such cancers are addicted to anaplastic lymphoma kinase activity. Several anaplastic lymphoma kinase inhibitors have been identified and are being evaluated in clinical trials. However patients with poor performance status (3 or 4) were not involved in these clinical trials, it has been unclear to use anaplastic lymphoma kinase-tyrosine kinase inhibitors for these patients.

Sepsis caused by Listeria monocytogenes during chemotherapy for small cell carcinoma of the thymus.

Background: Listeria monocytogenes is a facultative intracellular parasitic bacterium that is Gram positive, catalase positive, oxidase negative, and a facultative anaerobe. It is known to infect humans through food. It is a bacillus with low virulence, but can cause meningitis and sepsis in infants and immunocompromised patients.

The long-term survival of a thymic carcinoma patient treated with S-1: a case report and literature review.

Background: Thymic carcinoma is a rare neoplasm of the thymus. Systemic chemotherapy is an important therapeutic modality for thymic carcinoma. However, no standard chemotherapy for this carcinoma has yet been established.

Clinical application of immunocytochemical detection of ALK rearrangement on cytology slides for detection or screening of lung adenocarcinoma.

Unlabelled: Immunohistochemical screening of Anaplastic lymphoma kinase (ALK) rearrangement has been regarded essential and routinely carried out to select treatment for lung adenocarcinoma. However, difficulty to approach a tumor by transbronchial lung biopsy (TBLB), it often fails to obtain tumor tissues whereas tumor cells are contained in cytology specimens simultaneously obtained when the bronchoscopy is done. Therefore we evaluated the expression of ALK protein by using immunohistochemistry (IHC) on TBLB specimens and immunocytochemistry (ICC) on brushing smear cytology slides in the same cases, and compared the concordance rate of IHC and ICC results.

A case of lung adenocarcinoma harboring EGFR mutation and EML4-ALK fusion gene.

Background: Lung cancer is the leading cause of cancer-related death worldwide. Epidermal growth factor receptor (EGFR)--tyrosine kinase inhibitor (TKI) is used for the patients with EGFR-mutant lung cancer. Recently, phase III studies in the patients with EGFR-mutant demonstrated that EGFR-TKI monotherapy improved progression-free survival compared with platinum-doublet chemotherapy.

[A case of adenocarcinoma of the lung with a long-term therapeutic effect due to S-1 administered as the sixth regimen].

Parkin is expressed in vascular endothelial cells.

Mutations in the parkin gene are related with early-onset Parkinson's disease. Parkin is identified as an E3-ligase that combines target proteins with ubiquitin. alpha-Synuclein and synphilin-1 are substrates for E3-ligase activity of parkin and considered to be involved in the pathogenesis of Parkinson's disease.

[Predicted vales of respiratory function tests in young Japanese aged from 10 to 20 years].

To find predicted values of respiratory function tests in young persons in Japan, we measured slow vital capacity and forced vital capacity in 1,141 subjects aged from 10 to 20 years. The values obtained from 636 persons (363 males and 273 females) who were not smokers or had no suspected rhinitis or asthma were analyzed. Although FEV1% by the Gaensler and Tiffeneau methods were almost constant regardless of age, all other values of respiratory function tests increased with age and then reached a plateau level in late teens.

Small adenocarcinoma of the lung: prognostic significance of central fibrosis chiefly because of its association with angiogenesis and lymphangiogenesis.

To clarify the reason why central fibrosis (CF) is an important histological prognostic factor in small adenocarcinoma (SA) of the lung, tumor tissues from 50 patients with SA < or = 2 cm in diameter were investigated using immunohistochemical and in situ hybridization analysis for factors relating to extracellular matrix and vessels. CF was observed in 33/50 cases (66%). In adenocarcinoma areas, positive activity was observed with both primary antibodies and probes for matrix metalloproteinase-2 (MMP-2) in 11/50 patients (22%), membrane-type 1 matrix metalloproteinase (MT1-MMP) in 39/50 patients (78%) and tissue inhibitor of metalloproteinase-2 (TIMP-2) in 49/50 patients (98%).

Level of antibodies against mycobacterial glycolipid in the effusion for diagnosis of tuberculous pleural effusion.

Background: Diagnosing tuberculous pleural effusion (pTB) is often difficult because the culturing of tubercle bacilli results in a negative test in the majority of cases. Serological tests for the detection of antibodies to tuberculous glycolipid (TBGL) and lipoarabinomannan (LAM) have been introduced for the diagnosis of pulmonary tuberculosis. We examined the levels of these antibodies, adenosine deaminase (ADA) and interferon-gamma (IFN-gamma) in the pleural effusion and compared their diagnostic values in pTB.
