We report 2 patients with unilateral pulmonary edema after heart surgery who were successfully treated using venovenous extracorporeal membrane oxygenation (VV ECMO). Case 1 : A 35-year-old woman presented with dyspnea. Echocardiography showed severe mitral regurgitation (MR) and tricuspid regurgitation (TR) and therefore, mitral valve plasty (MVP) and tricuspid annular plasty (TAP) were performed via right thoracotomy. After weaning from cardiopulmonary bypass, respiratory failure occurred with expectoration of foamy sputum and it was difficult to maintain oxygenation. Therefore, we performed VV ECMO to maintain oxygenation. A chest X-ray film after surgery showed ipsilateral pulmonary edema. After weaning from VV ECMO, deep venous thrombosis occurred and therefore we inserted an IVC filter. Case 2 : A 67-year-old man, who had previously received aortic valve replacement experienced dyspnea and visited our hospital. Echocardiography showed an aortic root abscess, and therefore Bentall operation was performed. After weaning from cardiopulmonary bypass, oxygenation was difficult to maintain, and therefore we performed VV ECMO. A chest X-ray film post operatively showed right ipsilateral pulmonary edema. The patient was weaned from VV ECMO 5 days post operatively and was discharged 60 days post operatively. We believe that VV ECMO can be beneficial for patients with respiratory failure after heart surgery, but complications related to this approach such as DVT should also be considered.

A survey was carried out on how the To-no District is coping with the need of first aid for patients requiring life-supporting treatment before hospitalization. Although there were cities in this district where statistics on first aid were not available, the survey found that, during the 4-year period from 1994 through 1997, bystander CPR (cardiopulmonary resuscitation) saved 11.2% of the lives of patients with CPA (cardiopulmonary arrest). Incidentally, 11.3% of the population attended CPR courses offered by public institutions. Gifu Prefecture has helicopters for use in rescue work, but the survey found that some cities had not ever sponsored drills using helicopters in life-saving operations. Our findings revealed the indifference of the general public as well as administrators in this district toward emergency care. Public recognition of the importance of the care of suddenly ill or injured patients must be gained. Furthermore, acquisition of skills required for first aid by lay people and technical improvement of these skills in professional rescuers are necessary. The authors think that these are the community educational responsibility of hospitals and other medical institutions.

Seventy patients with rheumatic valvular disease were evaluated with preoperative CT scanning. The correlation of the obtained CT images to the operative findings were examined. Left atrial thrombi were found in 24 cases at the operation. CT scan had detected thrombi in 19 cases (79.2%) and echocardiography in 15 (62.5%). CT failed to find them in 5 cases in which the left atrial thrombi were less than 3g. Echocardiogram, however, failed to detect thrombi in 9 cases, the largest being 14g. There were 15 cases with left atrial calcification, in which 10 cases had left atrial thrombi. Nine cases out of these 10 cases had rough left atrial surface after thrombectomy. Early postoperative CT of 10 with left atrial calcification showed recurrent left atrial thrombi in 4 (40%) cases. Mitral valve calcification was found in 42 cases during operation. CT scan was able to detect it in 40 (95.2%), while echocardiogram detected in 34 cases (81.0%) (p<0.05). All mitral valves with calcification required replacement. Out of 30 cases with non calcified mitral valves, 9 underwent OMC, and the other 21 underwent mitral valve replacement. Aortic valve calcification was found in 9 out of 11 cases with aortic stenosis. All has been diagnosed by CT scan. In conclusion, 1. In detecting the left atrial thrombi, CT scan was superior to echo-cardiography, and provided useful information for planning the operative procedure including atrial approach and valvular manipulation. 2. CT scan could detect calcification of left atrial wall which had high incidence of thrombus formation and rough left atrial surface. 3. CT scan could detect calcification of both mitral and aortic valve, and showed the severity of valvular structural changes.

The purpose of this study is to evaluate the efficacy of hochuekkito for late-onset hypogonadism (LOH) patients. We administered hochuekkito 7.5 g/day for 8 weeks to 47 patients with LOH whose AMS scale was more than 27. We assessed the patients' symptom change with the AMS, SHIM, SDS, BDI, and SF-36. We measured their endocrine profiles and levels of their cytokines. At the end of study, 31 of 47 patients were evaluable. No significant difference in subjective symptoms was seen with any questionnaire after 8 weeks hochuekkito administration. However, hochuekkito significantly increased free testosterone and decreased ACTH/cortisol levels. Thus we believe hochuekkito is beneficial for the treatment of LOH.

Background/Aims:
Intralesional steroid injections have been administered as prophylaxis for stenosis after esophageal endoscopic submucosal dissection. However, this method carries a risk of potential complications such as perforation because a fine needle is used to directly puncture the postoperative ulcer. We devised a new method of steroid intralesional infusion using a spray tube and evaluated its efficacy and safety.
Methods:
Intralesional steroid infusion using a spray tube was performed on 27 patients who underwent endoscopic submucosal dissection for superficial esophageal cancer with three-quarters or more of the lumen circumference resected. The presence or absence of stenosis, complications, and the number of endoscopic balloon dilations (EBDs) performed were evaluated after treatment.
Results:
Although stenosis was not observed in 22 of the 27 patients, five patients had stenosis and dysphagia requiring EBD. The stenosis in these five patients was relieved after four EBDs. No complications related to intralesional steroid infusion using the spray tube were observed.
Conclusions
Intralesional steroid infusion using a spray tube is a simple and safe technique that is adequately effective in preventing stenosis Clinical trial number (UMIN000037567).

The number of fatalities in Japan attributable to lung cancer exceeded 50000 in 2001. It is socially desirable that various markers, which can be utilized for the prevention of lung cancer, be established. We believe that smoking or exposure to carcinogens in air induces mutations in bronchial and alveolar epithelia, leading to the development of lung cancer. It would be useful to have markers of individual differences in susceptibility to chemical carcinogen-induced lung cancer 1) to identify genetic polymorphisms of enzymes metabolizing chemical carcinogens and 2) to investigate the expression of enzymes metabolizing chemical carcinogens. In this paper, we review CYP expression in the bronchial epithelium. CYP1, CYP2 and CYP3 are expressed in the bronchial epithelium. We also show the relationship between the genetic polymorphisms of cytochrome P450 (CYP) and a person's susceptibility to chemical carcinogen-induced lung cancer. We demonstrate the relationship between cigarette consumption and the CYP expression profile in the bronchial epithelium. To maintain and promote public health, we must apply evidence, such as CYP polymorphisms and CYP profiles to disease prevention and also to aggressively advance evidence-based prevention (EBP) of lung cancer.

Objective:To assess the risk for hyperkalemia caused by treatment with angiotensin Ⅱ Type 1 receptor blockers (ARB) in clinical practice with Japanese medical database.Design:A cohort study in patients treated with ARB alone and those treated with calcium channel blockers (CCB) alone as control.Methods:The Diagnosis Procedure Combination (DPC) database provided by Medical Data Vision Co., Ltd. was used to identify patients who received a diagnosis of hypertension (ICD-10 codes, I10 to I15) and were treated with ARB or CCB from April 2008 to June 2017. A logistic regression model was applied to estimate adjusted odds ratios (OR) and their 95% confidence intervals (CI) in these patients. The outcome in the logistic model was hyperkalemia (serum potassium≧5.5 mEq/L) and the covariates were sex, age, renal insufficiency, hepatic insufficiency, and baseline serum potassium levels. And, subgroup analysis was also performed in patients with and without renal insufficiency.Results:The incidence of hyperkalemia (per 1000 person-years) with ARB was 39.4 and that with CCB was 32.6. And, median periods from the index date to the date of occurrence of hyperkalemia for both exposure and control groups were 36 days (Min-Max:12-85) and 51.5 days(Min-Max:8-88)respectively. However, treatment with ARB was not associated with occurrence of hyperkalemia (OR 1.26, 95%CI: 0.58-2.75). The risk for hyperkalemia among those with renal insufficiency was higher (OR 3.31, 95%CI: 1.39-7.88)and as baseline serum potassium increased, the risk increased as well (OR 9.20, 95%CI: 3.52-24.10). And, the subgroup analysis also showed that rare occurrence of hyperkalemia by ARB and elevation risk for hyperkalemia by baseline serum potassium.Conclusion:The clinical data showed rare occurrence of hyperkalemia caused by ARB, indicating that renal insufficiency and baseline serum potassium levels affected the onset of the disease in clinical practice. Previous studies also reported the effects of renal insufficiency and other factors on the onset of hyperkalemia. ARB should be prescribed carefully in patients with these factors, as is conventionally done.

We have previously reported on a predictive model for deficiency-excess pattern diagnosis that was unable to predict the medium pattern. In this study, we aimed to develop predictive models for deficiency, medium,and excess pattern diagnosis, and to confirm whether cutoff values for diagnosis differed between the clinics. We collected data from patients' first visit to one of six Kampo clinics in Japan from January 2012 to February 2015. Exclusion criteria included unwillingness to participate in the study, missing data, duplicate data, under 20 years old, 20 or less subjective symptoms, and irrelevant patterns. In total, 1,068 participants were included. Participants were surveyed using a 153-item questionnaire. We constructed a predictive model for deficiency, medium, and excess pattern diagnosis using a random forest algorithm from training data, and extracted the most important items. We calculated predictive values for each participant by applying their data to the predictive model, and created receiver operating characteristic (ROC) curves with excess-medium and medium-deficiency patterns. Furthermore, we calculated the cutoff value for these patterns in each clinic using ROC curves, and compared them. Body mass index and blood pressure were the most important items. In all clinics, the cutoff values for diagnosis of excess-medium and medium-deficiency patterns was > 0.5 and < 0.5, respectively. We created a predictive model for deficiency, medium, and excess pattern diagnosis from the data of six Kampo clinics in Japan. The cutoff values for these patterns fell within a narrow range in the six clinics.
