The main objective of this study was to describe the long-term results of left internal thoracic artery grafting of the left anterior descending artery with a sternotomy or anterior minithoracotomy without using extracorporeal circulation. From March 1997 to February 2000, a median sternotomy was performed in 8 patients and a minithoracotomy in 22 patients. We compared and analyzed the findings of these groups. An emergency operation was performed in 75% of the patients in the median sternotomy group and in 27.3% of those in the minithoracotomy group (p=0.03). The operation time was 2.1h in the median sternotomy group and 3.9h in the minithoracotomy group (p<0.01). The early graft patency rate was 100% in the median sternotomy group and 90.4% in the minithoracotomy group (NS). The five-year actuarial survival rate was 100% in the median sternotomy group and 86.4% in the minithoracotomy group. The five-year cardiac event free rate was 100% in the median sternotomy group and 86.4% in the minithoracotomy group. In conclusion, the results for the median sternotomy group were comparatively better than for minithoracotomy group. Minithoracotomy and median sternotomy have differences in operation time, early graft patency and early outcome. The median sternotomy technique therefore remains an invaluable operative modality for the treatment of one-vessel disease.

A main symptom of chronic fatigue syndrome (CFS) is fatigue which continues for more than 6 months and does not improve with rest, leading to a marked decrease in quality of life. Other problems include fever, sleep disorder, and headache. Etiologically, a preceding viral infection, immunological disorder, and changes in the central nervous system, especially in hippocampus have been reported. However, the precise pathogenesis of CFS has not been elucidated, and neither diagnostic markers nor effective treatments have yet to be discovered. Here, we report a case of CFS, successfully treated with Kampo medicines.
The patient was a 16-year-old high school student, who had received medical therapy for one year under the diagnosis of CFS. His chief complaint was a continuing fever and strong malaise after influenza infection. At his visit to our outpatient clinic, we confirmed that his symptoms met the criteria for CFS. A combination treatment with Kampo medicine (sanoshashinto) and duloxetine improved his malaise and fatigue in 4 weeks, but fever and anorexia remained. The addition of hochuekkito to the combination dramatically ameliorated his symptoms. This case suggests that Kampo medicines would contribute to the effective treatment of CFS, which is refractory to Western medicines.

Genome-wide association studies have identified various genetic variants associated with complex disorders. However, these studies have commonly been conducted in a cross-sectional manner. Therefore, we performed a longitudinal exome-wide association study (EWAS) in a Japanese cohort. We aimed to identify genetic variants that confer susceptibility to hypertension using ~244 000 single-nucleotide variants (SNVs) and physiological data from 6026 Japanese individuals who underwent annual health check-ups for several years. After quality control, the association of hypertension with SNVs was tested using a generalized estimating equation model. Finally, our longitudinal EWAS detected seven hypertension-related SNVs that passed strict criteria. Among these variants, six SNVs were densely located at 12q24.1, and an East Asian-specific motif (haplotype) ‘CAAAA’ comprising five derived alleles was identified. Statistical analyses showed that the prevalence of hypertension in individuals with the East Asian-specific haplotype was significantly lower than that in individuals with the common haplotype ‘TGGGT’. Furthermore, individuals with the East Asian haplotype may be less susceptible to the adverse effects of smoking on hypertension. The longitudinal EWAS for the recessive model showed that a novel SNV, rs11917356 of COL6A5, was significantly associated with systolic blood pressure, and the derived allele at the SNV may have spread throughout East Asia in recent evolutionary time.

We had previously reported a close association between pathological response and the maximum tumor standardized uptake value (SUVmax) measured by 18F-fluorodeoxyglucose positron emission tomography prior to chemotherapy in estrogen receptor (ER)-positive breast cancer. We hypothesized that glucose hypermetabolism by luminal B tumors may result in chemotherapy responsiveness. Using a single-gene expression assay, TargetPrint(R) (Agendia) and a 70-gene expression classifier, MammaPrint(R) (Agendia), we divided 20 patients with ER-positive primary breast cancer into luminal A and luminal B subtypes and compared the tumor SUVmax value between the two groups. A significantly higher SUVmax was measured for luminal B tumors (n=10; mean+/-SD, 7.6+/-5.6) than for luminal A tumors (n=10; mean+/-SD, 2.6+/-1.2; p=0.01). Glucose hypermetabolism could help predict intrinsic subtyping and chemotherapy responsiveness as a supplement to ER, progesterone receptor, HER2, and Ki-67 histochemical scores.

OBJECTIVESystemic and myelotoxic effects of 2,3,7,8-tetrabromodibenzo-p-dioxin (TBDD) were examined by the single administration of TBDD by gavage to rats.

METHODSFifteen Wistar rats of both sexes per group received 0, 10, 30, 100 or 300 μg TBDD/kg body weight. Rats surviving to the scheduled necropsy on Days 2, 7 and 36 after TBDD administration were examined for growth rate, organ weight, hematology, histopathology and adipose tissue levels of TBDD.

RESULTSThree 300 μg/kg-dosed females died on Days 21, 23 and 27, and exhibited a marked decrease in body weight, severe thymic atrophy, decreased bone marrow hematopoiesis and hemorrhage in the subarachnoid space of brain and spinal cord. TBDD-dosed surviving rats exhibited growth retardation, decreased bone marrow hematopoiesis, decreases in red blood cell counts, hemoglobin concentrations, and hematocrit values, an increase in reticulocytes and decreases in platelet counts, white blood cell counts and eosinophils. These signs suggested TBDD myelotoxicity. Splenic extramedullary hematopoiesis was increased in both sexes given TBDD, whereas atrophy of the splenic white pulp occurred only in TBDD-dosed females. Marked decreases in body weights and the size and weight of the thymus, severe thymic atrophy and death in TBDD-dosed females suggested a wasting syndrome. The adipose tissue level of TBDD culminated on Day 7 and decreased to 20-30% of the Day 7 level on Day 36.

CONCLUSIONSThe TBDD-induced effects were characterized by a wasting syndrome and myelotoxicity that appeared at the dose levels of 30 μg/kg and higher and caused death in 300 μg/kg-dosed females.

BACKGROUND: Studies on the adverse effects of Asian dust (AD) on respiratory function in children are scarce. The objective of this study was to examine the association between AD and respiratory function by measuring peak expiratory flow rates (PEFRs) in asthmatic children. METHODS: The study was carried out from March to May from 2014 through 2016. One hundred ten children with bronchial asthma were recruited from four hospitals in the Goto Islands and south Nagasaki area in Nagasaki prefecture. The parents were asked to record their children's PEFRs every morning/evening and clinical symptoms in an asthma diary. AD was assessed from light detection and ranging data, and a linear mixed-effects model was used to estimate the effects of AD on daily PEFR. Time-stratified case-crossover analyses were performed to examine the association between AD and asthma attacks defined by reduction levels in PEFR. RESULTS: AD was detected on 11 days in the Goto Islands, and on 23 days in the south Nagasaki area. After adjusting for age, sex, temperature, and daily oxidants, we found a consistent association between AD and a 1.1% to 1.7% decrease in PEFR in the mornings and a 0.7% to 1.3% decrease in the evenings at a lag of 0 to 5 days. AD was not associated with the number of asthma attacks, respiratory symptoms, or other symptoms at any lag days examined. CONCLUSIONS Exposure to AD was associated with reduced PEFR, although the effects were not large enough to induce clinically apparent symptoms, in clinically well-controlled asthmatic children.
