    Objective An impairment of gastric motility is strongly associated with the pathophysiology of functional dyspepsia (FD). Plasma ghrelin is one of the key molecules linked to gastric motility. Therefore, this study aimed to evaluate whether ghrelin (GHRL) gene polymorphisms are associated with clinical symptoms, the plasma ghrelin levels and gastric emptying in patients with FD as defined by the Rome III classification.
    Methods We enrolled 74 Helicobacter pylori-negative patients presenting with typical symptoms of FD (epigastric pain syndrome (EPS), n=23; postprandial distress syndrome (PDS), n=51) and 102 healthy volunteers. Gastric motility was evaluated according to the Tmax value and T1/2 using the 13C-acetate breath test. We used the Rome III criteria to evaluate upper abdominal symptoms and SRQ-D scores to determine the depression status. The Arg51Gln(346G->A), preproghrelin3056T->C, Leu72Met(408C->A) and Gln90Leu(3412T->A) polymorphisms were analyzed in DNA in blood samples obtained from the enrolled subjects. Genotyping was performed using polymerase chain reaction.
    Results There was a significant relationship (p=0.048) between the preproghrelin 3056TT genotype and the serum levels of acylated ghrelin in the H. pylori-negative FD patients. The preproghrelin 3056TT genotype was significantly (p=0.047) associated with the feeling of hunger in the H. pylori-negative FD patients.
    Conclusion The preproghrelin 3056TT genotype is significantly associated with the acylated ghrelin levels and the feeling of hunger in H. pylori-negative FD patients. Further studies are needed to clarify the association between the preproghrelin 3056TT genotype and lower plasma acylated ghrelin levels and the impact of this relationship on the feeling of hunger in H. pylori-negative FD patients.

    Objective To investigate the influence of acid reflux on chest pain and ischemic events and the effects of cardiac drugs on acid reflux in patients with coronary artery disease (CAD) and refractory chest pain.
    Methods Simultaneous 24-hour esophageal pH monitoring and 24-hour continuous electrocardiogram (ECG) (Holter) results were obtained for 64 patients. Ischemic events and cardiac drug prescriptions were compared between the patients with and without gastroesophageal reflux disease (GERD). Patients fulfilling the GERD criteria received 14-day therapy with omeprazole at a dose of 20 mg bid. The results of the 24-hour pH monitoring, Holter and the SF-36 questionnaire were compared before treatment and again after two weeks of therapy.
    Results GERD was identified in 38 (69%) patients, with 49% of all chest pain occurring in association with acid reflux. A higher incidence (p=0.033) and longer duration (p=0.040) of ischemic events were observed in the GERD (+) patients. More frequent combined use of cardiac drugs was found in the GERD (+) patients. However, fewer ischemic events and greater total SF-36 survey scores were noted after PPI therapy in the GERD (+) patients.
    Conclusion Acid reflux is common in patients with CAD and refractory chest pain. Refractory chest pain in patients with CAD can be partially noncardiac chest pain (NCCP) secondary to acid reflux. The combined use of common cardiac drugs may predispose or aggravate GERD. Short-term proton pump inhibitor (PPI) therapy not only restores a normal esophageal pH, but also significantly improves the general health-related quality of life (HRQL) of patients.

    Objective Malignant pleural effusions are commonly treated with tube drainage followed by chemical pleurodesis to maintain the patient's quality of life. While talc is now accepted to be a worldwide gold-standard sclerosing agent for treating malignant pleural effusion, it is not yet approved in Japan. Instead, many patients are administered OK-432 for pleurodesis, which carries the risk of complications such as high-grade fever, chest pain, anaphylactic shock, interstitial pneumonia and acute renal failure. To assess the efficacy and safety of talc as a sclerosing agent in the management of malignant pleural effusions in Japanese patients.
    Methods Pleurodesis was performed using 4 g of sterile talc with thoracoscopic talc poudrage or the administration of talc slurry via a chest tube in patients with malignant pleural effusions.
    Results A total of 57 patients were included. The success rate of pleurodesis assessed on chest radiography at 30, 90 and 180 days was 90.6%, 80.9% and 76.1%, respectively. Complications occurring after talc pleurodesis included fever in 10.5% of the patients and chest pain in 14.0% of the patients. No major complications were reported.
    Conclusion Talc pleurodesis is an effective and safe treatment for the management of malignant pleural effusion in Japanese patients.
