Mitsuo Hinoue, Hajime Hori
For a new desorption method development for working environment measurement, desorption efficiency of organic solvent vapors from an activated carbon was examined using desorption solutions that consisted of anionic and nonionic surfactants. Ten μl of an aqueous solution of isopropyl alcohol or methyl ethyl ketone diluted with distilled water was spiked into a 10 ml vial with a coconut-shell-activated carbon (100 mg). The vial was left for 24 h, and 5 ml a desorption solution was added. Afterwards, the vial was put into an incubator at 60°C and left for 24 h, then the desorption efficiency was determined by analyzing the headspace gas in the vial with a gas chromatograph equipped with flame ionization detector...

Nursing department students are expected to correctly grasp the entire concept of nursing through their education. The authors created a movie of a Nightingale ward (virtual ward, hereafter) with an architectural computer design software for education. The students' reaction to the virtual ward was categorized into three viewpoints: that of nurses, of patients, and of nurses and patients in common. Most of the reactions in each viewpoint were: "easy to observe patients" in the nurses' viewpoint; "no privacy" in the patients' viewpoint; and "wide room" in the common viewpoint, respectively...

A 61-year-old woman was referred to our hospital because of a right breast mass. A 19 mm hard mass was palpable in the A area of the right breast. A contrast-enhanced MRI showed rim enhancement at the peripheral region of the tumor, which was thought to represent the carcinoma component mainly at the periphery and the matrix component inside the tumor. A low density mass with rim enhancement at the peripheral region was observed in a contrast-enhanced CT, the same as in the MRI. Neither axillary lymph node metastasis nor distant metastasis was observed...

We report a surgical case of retroperitoneal paraganglioma. A paraganglioma is a catecholamine-producing tumor originating in the chromaffin cells of the sympathetic ganglion. It is a kind of pheochromocytoma which occurs on the outside of the adrenal gland. The patient was a 72 year old male with a history of hypertension and a pacemaker implantation. A mass in the ventral side of the right iliopsoas muscle was detected during a routine contrasting computed tomography (CT) examination for checking his pacemaker...

Workers who respond to large-scale disasters can be exposed to health hazards that do not exist in routine work. It is assumed that learning from past cases is effective for preparing for and responding to such problems, but published information is still insufficient. Accordingly, we conducted a literature review about the health issues and occupational health activities at the World Trade Center (WTC) terrorist attack and at the Fukushima Nuclear Power Plant accident to investigate how occupational health activities during disasters should be conducted...

Women who rear children have two types of roles: the maternal role and the self-role. Previous studies have suggested that maternal role satisfaction is related to anxiety, but the importance of self-role satisfaction in promoting the health of mothers has received less attention. The changing roles of women in society, especially in urban areas, have altered mothers' views of child-rearing. Our primary focus was on the relationship between maternal/self-role satisfaction and anxiety in mothers. To examine this, we conducted a cross-sectional survey using self-administered questionnaires that were distributed in 2011 to 2,342 mothers attending the 18-month health checkup of their children, in 7 cities of the Tokyo metropolitan area...

Multifocal micronodular pneumocyte hyperplasia (MMPH) is pathologically characterized by multifocal nodular hyperplasia of type Ⅱ pneumocyte-like cells. MMPH is usually complicated with tuberous sclerosis complex (TSC). MMPH patients tend to be asymptomatic or only slightly symptomatic. MMPH tends to progress slowly and needs no treatment. We herein describe two cases of MMPH with its characteristic radiological features and clinical manifestations of TSC. Case 1: a 20-year-old female with definitive TSC in infancy...

Inhalation tests are the gold standard test for the estimation of the pulmonary toxicity of respirable materials. Intratracheal instillation tests have been used widely, but they yield limited evidence of the harmful effects of respirable materials. We reviewed the effectiveness of intratracheal instillation tests for estimating the hazards of nanomaterials, mainly using research papers featuring intratracheal instillation and inhalation tests centered on a Japanese national project. Compared to inhalation tests, intratracheal instillation tests induced more acute inflammatory responses in the animal lung due to a bolus effect regardless of the toxicity of the nanomaterials...

Diallylamine-maleic acid copolymer (DAM)-nonwoven fabric (DAM-f), a fibrous adsorbent, contains DAM with zwitter-ionic functional groups and forms a hydration layer on the surface. The aim of this report was to evaluate the adsorption selectivity of DAM-f to semi-volatile organic acid (C1-C5). In the aqueous phase, formic acid dissolved in the hydration layer bound to the imino group of DAM-f due to anion exchange interaction. In the gas phase, the adsorption amounts of organic acids increased with the exposure time...

It is difficult to understand nursing practically for students who have just started studying nursing, because they cannot imagine the actual medical scene. The authors expect that they can improve nursing learning through experiences in virtual medical environments supported by ICT (information and commnication technology). We developed teaching materials in nursing education, and in a previous study we reported that the use of a virtual hospital was useful for students who had not had medical experience. The aim of the present study was to have students consider the meaning of a hospital room ceiling...

The effects of color perception are utilized in visual displays for the purpose of safety in the workplace and in daily life. These effects, generally known as color functionality, are divided into four classifications: visibility, legibility, conspicuity and discriminability. This article focuses on the relationship between the color functionality of color schemes used in visual displays for occupational and environmental safety and color vision deficiency (particularly congenital red-green color deficiency), a critical issue in ophthalmology, and examines the effects of color functionality on the perception of the color red in individuals with protan defects...

Toshiyuki Umata
Nuclear fusion technology is expected to create new energy in the future. However, nuclear fusion requires a large amount of tritium as a fuel, leading to concern about the exposure of radiation workers to tritium beta radiation. Furthermore, countermeasures for tritium-polluted water produced in decommissioning of the reactor at Fukushima Daiichi Nuclear Power Station may potentially cause health problems in radiation workers. Although, internal exposure to tritium at a low dose/low dose rate can be assumed, biological effect of tritium exposure is not negligible, because tritiated water (HTO) intake to the body via the mouth/inhalation/skin would lead to homogeneous distribution throughout the whole body...

REVIEW
Kuninobu Kashiyama, Shinjo Sonoda, Yutaka Otsuji
The main risk factors in ischemic heart diseases, including myocardial infarction, are hypertension, dyslipidemia, diabetes, obesity and smoking. The incidence of ischemic heart disease in Japan has been lower than that in Western countries because of differences in lifestyle and the anatomy of the coronary arteries, but the situation has been changing recently because of the westernization of lifestyle. Cardiovascular diseases have become the second most common cause of death in Japan, and 40% of those deaths are attributed to ischemic heart disease...

We analyzed the effects of 100 mg/day sitagliptin and a switch to mitiglinide calcium hydrate/voglibose compound tablets (MIT/VOG) in patients with type 2 diabetes mellitus (T2DM) treated with 50 mg/day sitagliptin. Five patients with T2DM treated with 50 mg/day sitagliptin and hemoglobin A1c (HbA1c) of ≥6.5% were switched to MIT/VOG, or the dose of sitagliptin was increased to 100 mg/day. The effects of the changes in therapy were compared in a crossover fashion by continuous glucose monitoring. The primary endpoint was mean amplitude of glycemic excursions (MAGE), and the secondary end points were 24-hour mean blood glucose level and mean blood glucose level from 0:00 a...

The purpose of this study was to extract the risk factors recognized by students before pediatric nursing practice in order to conduct medical safety education based on student's learning readiness. Third-year nursing students of A nursing college used the P-mSHELL model to find the risk factors in a simulated pediatric hospital room, and the researchers analyzed the contents. The students recognized four categories of risk factors: "burden on the family", "characteristics of the infant", "characteristics of children with disease", and "the family's cognition and understanding"...

Although chronic obstructive pulmonary disease (COPD) affects one in several smokers, only a few patients are correctly diagnosed compared to the estimated number of patients. Several recent reports indicate that the development of rotator cuff tears is related to smoking. In this study, we investigated smoking status in patients with rotator cuff tears and evaluated the possibility of undiagnosed COPD by a pulmonary function test. The subjects were 150 consecutive patients over 40 years old, who had been diagnosed with rotator cuff tears and had been examined by a pulmonary function test before surgery in our orthopedic department between April 2011 and June 2015...
