Effectiveness of Saireito, a Traditional Japanese Kampo Herbal Medication, on Pacemaker-Related Pleural Effusion: A Case Report.

BACKGROUND Post-cardiac injury syndrome, including pleural effusion as a delayed complication of permanent pacemaker implantation, has rarely been reported. To resolve pleural effusion, prolonged chest tube placement is often required. Anti-inflammatory agents combined with diuretics are also often prescribed. Saireito, a Japanese herbal medication, which is a combination of Goreisan and Shousaikoto, has both anti-inflammatory and water-modulation properties and has been used for edema (lymph edema, cerebral edema) and inflammation (chronic nephritis). CASE REPORT We describe a 71-year-old woman with a history of syncope and bradycardia who underwent dual permanent pacemaker implantation (placed in the right chest because of a persistent left superior vena cava) without complications. Two months later, she came to the hospital as an outpatient with a dry cough, and was diagnosed with right-sided pleural effusion. A pleural fluid analysis revealed exudative effusion, according to Light's criteria. The fluid was negative for infectious etiology. Chest X-ray, computed tomography, and echocardiography revealed no signs of pericardial effusion or perforation of the pacemaker lead to outside the heart. The pleural effusion persisted despite use of anti-inflammatory medication for several weeks and diuretics for a short period. Saireito was administered with good response; the pleural effusion resolved completely and there was no deterioration of renal function. CONCLUSIONS The present case highlights the clinical significance of Saireito as an effective therapeutic agent for late-onset pacemaker-related pleural effusion, without adverse effects such as renal dysfunction.

A Case of Takotsubo Cardiomyopathy with a Rare Transition Pattern of Left Ventricular Wall Motion Abnormality.

BACKGROUND Takotsubo cardiomyopathy is characterized by apical ballooning and excessive constriction of the base of heart. However, reverse takotsubo cardiomyopathy, wherein ballooning from the mid-ventricle to the base of the heart occurs with excessive constriction of the apex, has also been reported. We report a case of a transition from atypical wall motion abnormality to a typical takotsubo cardiomyopathy pattern. CASE REPORT A 54-year-old woman was following excessive sugar and dietary restrictions because of concerns regarding her blood sugar levels while receiving treatment for diabetes at another hospital. She presented at our hospital with general malaise and chest discomfort after several days of significantly increased workload. On admission, blood tests showed elevated cardiac enzymes. Electrocardiogram showed ST elevation of V2-V3 and poor R-wave enhancement of the anterior precordial lead. Coronary angiography showed no significant stenosis; however, left ventricular (LV) angiography showed a decrease in mid-ventricular wall motion. On the basis of these findings, she was diagnosed with a reverse takotsubo cardiomyopathy. We initiated conservative treatment for her condition. During her treatment, the LV wall motion showed a typical pattern of the apical ballooning that is characteristic of takotsubo cardiomyopathy. This LV wall motion was normalized on day 22 of the onset. CONCLUSIONS We observed a rare case of takotsubo cardiomyopathy where the pattern of LV wall motion abnormality changed over time. This case suggests that it is necessary to follow up LV abnormality over time rather than rely on single-point observations in cases with takotsubo cardiomyopathy.

Clinical Features of Spontaneous Isolated Dissection of Abdominal Visceral Arteries.

BACKGROUND: Spontaneous isolated dissection of abdominal visceral arteries without aortic dissection is rare and its pathology and prognosis are not yet clear; therefore, therapeutic strategies for this disease have not been established. The present multi-institution investigational study analyzed the clinical features of patients with spontaneous isolated dissection of abdominal visceral arteries. METHODS: A total of 36 patients diagnosed as spontaneous isolated dissection of abdominal visceral arteries from January 2010 to October 2016 were enrolled. The medical data of the patients were retrospectively reviewed. Imaging characteristics were evaluated. Spontaneous isolated dissection of abdominal visceral arteries was detected on upper abdominal computed tomography examination in almost patients, and was detected on magnetic resonance imaging in one patient. RESULTS: Of the 36 cases, 26 cases involved the superior mesenteric artery dissection, nine involved the celiac artery, two involved the splenic artery, one involved the common hepatic artery, one involved the gastroduodenal artery and one involved the left gastric artery. Among the 36 patients, 20 had hypertension and 14 were current smokers. Additionally, only one patient had diabetes and four patients had dyslipidemia. Moreover, 32 cases complained of pain including abdominal pain and back pain, one had cough and three had no symptoms. Of the 36 patients, 34 cases (94.4%) were treated conservatively, and two (5.6%) required intravascular treatment. All patients were discharged without complications. CONCLUSIONS: Our findings indicate that hypertension and smoking might be closely involved in the pathogenesis of spontaneous isolated dissection of abdominal visceral arteries, whereas dyslipidemia and diabetes might be less involved. Additionally, few asymptomatic patients were accidentally diagnosed, indicating that the absence of symptoms cannot be used to rule out the presence of this disease. Randomized clinical trials cannot be performed because a considerable number of cases are required. Therefore, detailed descriptions of clinical features, as provided in our report, are important.

[Study of the bacterial reduction effects of dry hand rubbing without disinfectant].

Handwashing is the most basic method of preventing infection. Hand rubbing with an alcohol-based handrub, is the most efficient and popular method. We found in several case studies that 3 minutes of dry hand rubbing without any disinfectant decreases the number of hand bacteria. In this study of 54 samples taken from 47 test subjects, we tried to determine how effectively this method decreases hand bacterial numbers. Except for 12 samples that were indeterminate, the number of hand bacteria in 36 (85.7%) out of 42 samples decreased. The average rate of decrease was 49.4% and the maximum rate was 98.3%. Although the most effective duration of dry hand rubbing varied among individuals, we estimated that 2 minutes is optimal. As dry hand rubbing without disinfectants decreases hand bacteria, we suggest that it can be an effective alternate method in emergency situations when water, soap or disinfectants are unavailable.
