Rationale: Desert dust particles, including quartz, which causes inflammatory responses in the airway in animal studies, are transported to widespread regions around the globe. Epidemiologically, areas impacted by desert dust storms, such as communities in the Middle East and the Caribbean, seem to have higher incidences of asthma than might be expected. Objectives: We investigated the magnitude of association between airborne mineral dust concentration and hospitalization of children for asthma exacerbation by using Light Detection And Ranging (LIDAR) with a polarization analyzer for an exposure measurement, which can distinguish mineral dust particles from other particles. Methods: A case-crossover design was used. The exposure measurement was LIDAR's nonspherical extinction coefficient. The outcome measurement was hospitalization of children aged 1 to 15 years for asthma exacerbation in eight principal hospitals in Toyama, a local area in Japan bordering the Japan Sea, during February to April, 2005 to 2009. Measurements and Main Results: During the study period, there were 620 admissions for asthma exacerbation, and 6 days with a heavy dust event (daily mineral dust concentration > 0.1 mg/m 3). Conditional logistic regression showed a statistically significant association between asthma hospitalization and a heavy dust event. The crude odds ratio (OR) of the heavy dust event for hospitalization on the day was 1.88 (95% confidence interval [CI], 1.04-3.41; P = 0.037), and the O Rof heavy dust event during the previous week was 1.83 (95% CI, 1.31-2.56; P = 0.00043). The OR adjusted by other air pollutant levels, pollen, and meteorological factors was 1.71 (95% CI, 1.18-2.48; P = 0.0050). Conclusions: Heavy dust events are associated with an increased risk of hospitalizations for asthma.

Background: Rhinitis is a common disease, and its prevalence is increasing worldwide. Several studies have provided evidence of a strong association between asthma and rhinitis. Although smoking and obesity have been extensively analyzed as risk factors of asthma, associations with rhinitis are less clear. Objective: The aims of our study were (i) to evaluate the prevalence of rhinitis using the European Community Respiratory Health Survey (ECRHS) questionnaire in Japanese adults and (ii) to evaluate the associations of smoking and body mass index (BMI) with rhinitis. Methods: Following our study conducted in 2006-2007 to determine the prevalence of asthma using the ECRHS questionnaire, our present analysis evaluates the prevalence of rhinitis and its association with smoking and BMI in Japanese adults 20-79 years of age (N = 22819). We classified the subjects (20-44 or 45-79 years) into four groups as having (i) neither rhinitis nor asthma; (ii) rhinitis without asthma; (iii) asthma without rhinitis; or (iv) rhinitis with asthma. We then evaluated associations with smoking and BMI in each group. Results The overall age-adjusted prevalence of rhinitis was 35.1% in men and 39.3% in women. A higher prevalence was observed in the younger population than in the older population. Active smoking and obesity were positively associated with asthma without rhinitis. In contrast, particularly in the 20- to 44-year age-group, active smoking and obesity were negatively associated with rhinitis without asthma. Conclusion The results of the present study suggest that smoking and obesity may have different effects on the development of rhinitis and asthma. © 2012 John Wiley & Sons A/S.

Background: In rheumatoid arthritis (RA), matrix metalloproteinase-3 (MMP-3) and oxidative stress contribute to joint destruction. However, little is known about the relationship between MMP-3 and oxidative stress in RA. Methods: We measured the albumin-thiol redox state as a marker of oxidative stress, MMP-3, and the DAS-28 score calculated using CRP values among forty-seven patients (9 males and 38 females) with RA. According to the serum MMP-3 levels, they were divided into two groups (group A: within normal ranges of 36.9 - 121.0 ng/mL for men and 17.3 - 59.7 ng/mL for women; group B: above normal ranges). Results: The albumin-thiol redox state in group B was significantly oxidized compared with that in group A (p < 0.01). The percentage of oxidized albumin-thiol showed a positive correlation with serum MMP-3 (r = 0.52). DAS-28 and CRP were also correlated with the percentage of oxidized albumin-thiol (r = 0.46, r = 0.44). Conclusions: The albumin-thiol redox state was significantly oxidized in correlation with serum MMP-3 elevation in RA.

Aim: Hormone replacement therapy (HRT) for climacteric symptoms is effective for vasomotor symptoms, such as hot flushes and sweating, but not for various psychological symptoms, such as anxiety, depression, and irritability. In such cases, prescribing Kampo, traditional herbal medicine, is sometimes considered. However, the effectiveness of Kampo has not been clearly shown. We examined the clinical effect of Kami-shoyo-san, a herbal formula commonly prescribed for climacteric symptoms in a Japanese Kampo clinic. Methods: There were 180 patients who initially consulted our Kampo Outpatient Clinic due to the absence of a response to HRT or unsatisfactory improvement. Out of 180 patients, 45 patients received a Kami-shoyo-san extract for 4 weeks based on patient-centered Kampo diagnosis. We evaluated the severity of climacteric symptoms based on the visual analogue scale (VAS) score before and after 4 weeks of Kami-shoyo-san administration. Furthermore, the severity of each symptom before treatment was compared between the responders and non-responders. Results: Kami-shoyo-san was effective in 33 (73.3%) of the 45 patients. After treatment, on the whole, the VAS score significantly decreased (P < 0.0001). Concerning vasomotor symptoms and psychological symptoms, each VAS score significantly decreased (P < 0.0001). When comparing the severity of pretreatment symptoms between responders and non-responders, symptoms, such as 'insomnia', 'depression', and 'vertigo' were significantly more marked in the responders (P < 0.05). Conclusion: The results of this study suggest that Kami-shoyo-san relieved both vasomotor and psychological symptoms, and especially in patients with marked psychological symptoms, it exhibited potent effects. © 2012 The Authors.

Aims: The manner in which pathological lesions of corticobasal degeneration (CBD) progress remains poorly understood. Because the pathology of early disease stages may be fundamental for elucidating a border between clinical and preclinical states of CBD, the present study aimed to detect preclinical or early clinical CBD cases by examining a series of forensic autopsy cases. Methods: A series of 887 brains from medicolegal autopsies was examined. Immunohistochemistry for tau (AT8, 3, and 4-repeat-tau) and Gallyas-Braak was applied for diagnosis. Neuropathological diagnosis of CBD followed criteria updated in 2002 by a working group. Results: Three autopsy cases (0.34%) were identified that fulfilled CBD pathological criteria. Two cases were preclinical or very early clinical cases without brain atrophy; the other case had exhibited a 5-year history of advanced frontotemporal dementia. Significant microscopic differences between the subclinical and clinical cases included occurrence of neuronal loss with spongiosis and gliosis, as well as a difference in degree of tau pathology in the superficial layer of the neocortical areas and white matter. Anatomical hierarchy of tau pathology in the brain was not evident, but asymmetric neocortical tau pathology that might influence the clinical phenotype was found in preclinical and early clinical cases. Conclusions: The results revealed the pathological features of subclinical and early clinical CBD cases. Comparison with clinical CBD cases showed that neuronal loss, cortical atrophy and volume reduction of white matter may be involved in the occurrence of clinical symptoms of CBD. Additionally, immunohistochemistry is essential for detecting preclinical CBD cases, regardless of case selection. © 2015 British Neuropathological Society.

Background and Purpose: Laparoscopic resection of extra-adrenal pheochromocytoma (EAPs) necessitates meticulous surgical procedures because of changes in anatomic disposition and/or proximity to major blood vessels. Complete resection can be traumatic and may cause an increase in catecholamine levels. We present our experiences with laparoscopic resection of EAP (LEAP) and compare the intraoperative hemodynamics with those during laparoscopic resection of adrenal pheochromocytoma (LAP). Patients and Methods: We retrospectively reviewed the medical records of five patients who underwent LEAP (retrocaval EAP, n=2; interaortocaval EAP, n=1; periadrenal EAP, n=2) and five who underwent LAP between October 2001 and October 2011. We also evaluated fluctuations in blood pressure (BP) reported during both surgeries. Results: The tumors were successfully resected under laparoscopic guidance in both groups, and conversion to open surgery or blood transfusion was not needed. Intraoperative hypertension (BP>200 mm Hg) was observed in three LEAP and four LAP patients, whereas intraoperative hypotension (BP<80 mm Hg) was observed in five LEAP and three LAP patients. No significant differences were observed between groups, however. Conclusions: Laparoscopy is the method of choice for surgeons experienced in EAP resection because it is feasible and reproducible with appropriate preoperative planning, similar to LAP. © 2013 Mary Ann Liebert, Inc.

A 78-year-old man with complaints of appetite loss and weight loss visited our hospital in November 2006. Positron-emission tomography and computed tomography (PET/CT) showed swollen lymph nodes in the abdominal para-aorta, mediastinum and neck, with intense FDG accumulation. The pathological findings of the cervical lymph nodes revealed small-cell cancer. We diagnosed extensive small-cell lung cancer (SCLC), which occurred primarily in the left upper lobe. As subsequent CT revealed spontaneous shrinkage of the pulmonary nodule and swollen lymph nodes, the clinical course was monitored without anticancer therapy. In February 2007, progressive muscle weakness of the lower extremities developed. In July he was admitted with respiratory failure and required mechanical ventilation. Although we did not administer anticancer therapy due to his poor performance status, he survived for 30 months receiving mechanical ventilation, and the tumors continued to grow moderately. We diagnosed Lambert-Eaton myasthenic syndrome (LEMS) based on the clinical symptoms, the presence of anti-VGCC antibodies and waxing phenomenon on electromyography obtained in April 2009. Chemotherapy with amrubicin shrank the tumors, but his muscle weakness did not improve. Previous reports showed that a prognosis of SCLC with LEMS was better than that without LEMS. In this case, the tumors showed spontaneous regression without any anticancer therapy, and then increased moderately. The immune response was considered to have affected tumor growth.

We report a case of a 59-year-old woman who was forced to undergo mastectomy of the right breast (Rt Bt) plus axillary lymph node (Ax) dissection for right breast cancer at another hospital. The pathological diagnosis was invasive ductal carcinoma( scirrhou[s sci], pT2N2M0, Stage IIIA, estrogen recepto[r ER+], progesterone recepto[r PgR+], human epidermal growth factor receptor-2[HER2][2+]). Although no recurrence was observed after postoperative adjuvant chemotherapy and endocrine therapy, skin metastasis on the left back and pleuritis carcinomatosa were detected at our hospital 9 years and 6 months after the operation. Thereafter, bone metastasis, contralateral lymph node metastasis, and frequent occurrence of hepatic metastasis were sequentially detected. The patient was treated with chemotherapy (a total of 4 regimens) and endocrine therapy in addition to radiation therapy for lymph node metastasis over a period of approximately 2 years and 3 months; however, disease control was poor. Therefore, combined chemotherapy with paclitaxel and bevacizumab was initiated from February 2012. Soon after the initiation of combination therapy, the serum carcinoembryonic antigen (CEA) level gradually reduced and computed tomography (CT) revealed that the multiple-organ metastases had remarkably reduced in size. The response was classified as a clinical partial response (cPR). Although adverse events such as peripheral neuropathy, nose bleeding, and high blood pressure were observed, these were all of lesser that Grade 2 severity. The efficacy of chemotherapy was noted for 11 months.

Various conservative treatments for cervical pregnancy have been reported. However, unlike tubal ectopic pregnancy, the treatment of cervical pregnancy has not been well established. For patients who desire fertility preservation, treatment with methotrexate chemotherapy carries a high success rate for preservation of the uterus.When methotrexate is injected i.v. or i.m., expulsion of pregnant tissue occasionally takes up to 1 month. In this report, we present four cases of cervical pregnancy which were successfully managed by methotrexate injection into the bilateral uterine arteries. In cases presenting with massive bleeding, embolization of the bilateral uterine arteries was performed. Cervical pregnancy was aborted within 8 days safely, and fertility could be preserved without harmful side-effects. © 2014 Japan Society of Obstetrics and Gynecology.

In patients undergoing FOLFOX6 therapy for the treatment of unresectable/recurrent colorectal cancer, control of cumulative peripheral neuropathy is problematic. In our department, we stop using mFOLFOX6 as a primary therapy after 6 to 8 courses. Instead, we use mFOLFOX6 as a secondary therapy, and re-introduce mFOLFOX6 as a tertiary therapy; the patients undergoing this treatment protocol were included in Group A. We have studied the degree of neurotoxicity and the time of its occurrence in these patients compared to those undergoing the standard method (Group B; 12 cases). Grade 3 peripheral neuropathy was observed in both the groups. In Group B, peripheral neuropathy occurred in the primary treatment period, whereas in Group A, it appeared in the tertiary treatment period. Moreover, in Group A, we observed Grade 2 peripheral neuropathy in the primary treatment period in 3 cases, but this was promptly resolved after the therapy was shifted to the secondary treatment period. The period with neurological toxicities was shorter in Group A compared to Group B. When treating colorectal cancer with chemotherapy, it is important to elucidate how the prognosis can be improved while maintaining the quality of life( QOL). In our department, we place a greater emphasis on the QOL of the patient.
