    Obstructive Sleep Apnea (OSA) is a common disease associated with major cardiovascular diseases. Male subjects are more at higher risk for OSA than female subjects. The Berlin questionnaire is a beneficial screening tool for OSA and has 14 items. The Berlin questionnaire may need some adjustment for Thai or Asian populations. We aimed to find items that should be asked in the Berlin questionnaire to identify high risk for obstructive sleep apnea among Thai male healthcare workers. This study was performed in Thai male healthcare workers over the age of 35 and currently working at the Faculty of Medicine, Khon Kaen University. The Thai version of the Berlin questionnaire was randomly distributed. A study population of 273 subjects was required to provide a confidence value of 95%. An item analysis of the Berlin questionnaire was evaluated as independent factors for being high risk of OSA by using a multivariate logistic regression analysis. Of the 273 distributed questionnaires, 135 subjects returned then (49.5% response rate). Of those, 41 (30.4%) were identified as being at high risk of OSA. Only three items of the Berlin questionnaire, including frequent snoring, high body mass index and hypertension, were independently associated with being at high risk for OSA. In conclusion, the Berlin questionnaire can be shortened to identify high risk for OSA by itself; not polysomnography.

    There are several causes of atypical femoral fractures (AFF) in elderly Japanese patients, including longterm bisphosphonate (BP) use or bowed femoral shaft stress fractures, but the available sample size for examining AFF etiology in a single institution is limited. The purpose of this study was to categorize the characteristics of AFF by analyzing the data compiled on patients treated at our hospital and at affiliated institutes. This multicenter, retrospective, observational study included 34 AFF cases (bilateral AFF 10) in one male and 23 female patients (age range 30–90 years, mean age 73.0 years). Evaluation measures included the presence/absence of BP use, duration of BP use, history of other drug use, presence/absence of comorbidities, fracture site, presence/absence of femoral lateral bowing, bone biopsy parameters, and time to bone union. Nineteen patients were prescribed BP for osteoporosis (duration range 4–10 years, mean duration 6.1 years). Subtrochanteric and femoral shaft fractures were seen in 16 and 18 cases, respectively (complete fractures 22, incomplete fractures 12). Femoral lateral bowing (n = 16) occurred with femoral shaft fractures. Mean time to bone union was 9.0 months (complete fractures 11.3 months, incomplete fractures 3.7 months). AFF could be substantially caused by three factors: BP use, drugs other than BP/comorbidity, and femoral lateral bowing. Twenty four patients were classified as having BP-related-type (n = 2), drug/comorbidity-type (n = 3), lateral bowing-type (n = 2), or mixed-type (n = 17) AFF. AFF etiology cannot be explained by a single cause; thus, a multifactorial etiology, including poor bone quality due to mutual interactions and mechanical stress, seems to be responsible for the occurrence of AFF.

    The passive sampler is a simple device for collecting gaseous compounds. It is affected by environmental conditions such as relative humidity, but a dehumidification system (DHS) has not been developed for it. We have developed a dehumidification device for the passive sampler for determining 1,3-butadiene. It consists of a passive sampler surrounded by a DHS consisting of a basket filled with granular magnesium perchlorate as the dehumidification agent. The passive sampler consists of a porous polytetrafluoroethylene tube packed with Carboxen 1000 adsorbent. We compared the amounts of water adsorbed on the Carboxen 1000 adsorbent in the presence and in the absence of the DHS; the results showed that the DHS prevented water from entering the sampler. Volatile organic compounds that entered the sampler were collected by the Carboxen 1000 adsorbent. In the case of 1,3-butadiene, much higher amounts were collected by the passive sampler with the DHS than without it. This may be due to interference of adsorption or acceleration of 1,3-butadiene degradation by the water-soluble oxidant on the surface of the Carboxen 1000 adsorbent.

    Culture-independent methods to detect microorganisms have been developed in parallel with traditional culture-based methods ever since the classification of bacteria based on 16S rRNA gene sequences was advocated in the 1970s. The development and the prevalence of culture-independent molecular technologies have provided revolutionary progress in microbial studies. The development of these technologies contributes significantly to the research of microorganisms that cannot be detected by traditional methods such as culture-dependent methods.Many molecular methods targeting the 16S rRNA gene, such as fluorescence in situ hybridization (FISH), quantitative PCR, terminal restriction fragment length polymorphism (T-RFLP), denaturing-gradient gel electrophoresis (DGGE), clone library analysis, and next-generation DNA sequencing (NGS) technologies, have been applied to various microbial studies. Notably, the advent of NGS technologies enabled a large-scale research of the bacterial community. Many recent studies using the NGS technologies have revealed that a larger number of bacteria and taxa than previously thought inhabit various parts of the human body and various places on the earth. The principles and characteristics of each molecular method are different, and each method possesses individual advantages; for example target specificity, comprehensiveness, rapidness, and cost efficiency. Therefore it is important that the methods used in studies are suitable for the objective and materials. Herein, we highlights molecular approaches targeting the 16S rRNA gene in bacterial community analysis, and focuses on the advantages and limitations of each technology.

    Meige syndrome is a relatively rare type of oral facial dystonia. The dominant symptoms involve involuntary eye blinking and chin thrusting. Some patients may experience excessive tongue protrusion, squinting, muddled speech, or uncontrollable contraction of the platysma muscle. A 44-year-old Japanese male was suffering from schizophrenia. The initial presentation of his psychosis consisted of auditory hallucinations, delusions of persecution, psychomotor excitement, loosening association, and restlessness. After being prescribed several antipsychotic drugs, risperidone was started and gradually increased to 4 mg/day. The above symptoms were relieved, particularly auditory hallucination and excitement were promptly improved. Persecutory delusion, however persisted, and deteriorated. At one year after the start of this risperidone regimen, he exhibited severe blepharospasm symptoms (increased rate of eye blinking, light sensitivity) and oromandibular symptoms (trismus, jaw pain, dysarthria). He was diagnosed with Meige syndrome. His antipsychotic drug was changed from risperidone to paliperidone. Two months after switching from risperidone to paliperidone, his eye blinking, light sensitivity, jaw pain, and trismus gradually improved, although the dysarthria persisted. Six months after starting paliperidone, his symptoms of Meige syndrome were completely remitted. He has been well without relapse at 12 mg/day of paliperidone. The case suggests that Meige syndrome is relieved by changing from risperidone to paliperidone. The precise mechanism of the relief remains, however, unknown.

    Myringoplasty is one of the basic procedures in otologic surgery, and is important to achieve good hearing outcome. The temporal fascia is most widely used and considered to be a stable graft in this procedure, although 10-20% of patients develop reperforation after surgery, which is often hard to repair, even by revision surgery. We herein conducted revision myringoplasty using a cartilage graft to repair postoperative reperforation in 7 patients (8 ears) with chronic otitis media. The patients were 3 males and 4 females, aged 13-80 years with an average of 53.9 years. A cartilage graft was harvested from the tragus, sliced in 0.3 mm thickness with perichondrium attached on one side, and trimmed into an appropriate shape and size. The graft was then underlaid beneath the perforation and fixed with fibrin glue. The operation was Wullstein type I tympanoplasty in 5 ears and myringoplasty in 3 ears, using the temporal fascia in 7 ears and subcutaneous tissue in 1 ear. The postoperative follow-up period ranged from 16 to 44 months with an average of 30.0 months. Perforation of the tympanic membrane was successfully closed in 7 ears (87.5%). Hearing outcome was judged successful in 5 ears (62.5%) according to the criteria of the Otological Society of Japan (postoperative hearing level < 30 dB, hearing gain > 15 dB, or postoperative air-bone gap < 15 dB). These results indicate that cartilage is a stable and reliable graft material for revision myringoplasty to repair postoperative reperforation in patients with chronic otitis media.

    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. They consisted of 96 men and 54 women, which included 59 non-smokers (39.3%), 62 ex-smokers (41.3%), and 29 smokers (19.3%). The smoking rate of the subjects was the same as that of the general Japanese population. However, the ever-smokers who smoked more than 21 cigarettes per day were 31.9%, which was high compared to the Japanese ever-smokers population, i.e. 15.2% of men and 5.5% of women. Twenty-five subjects (16.7%) showed airflow limitation, and they consisted of 7 cases of COPD, 3 cases of bronchial asthma, one case of bronchiectasis, and 14 undiagnosed cases. The undiagnosed cases consisted of 7 non-smokers, 5 ex-smokers, and 2 smokers. Their stages of COPD were stage 1 in 11 cases and stage 2 in 3 cases. The prevalence of airflow limitation increased with increasing age: 0% for 40’s, 8.3% for 50’s, 20.7% for 60’s, and 25.6% for over 70’s. From these results, we recognized that paying attention to the numbers of cigarettes smoked per day are important in addition to the smoking history, for the patients with rotator cuff tears. Also, sharing the data of a pulmonary function test before surgery can contribute to the early diagnosis of COPD.

    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”. There were three categories of risk factors related to “the environment”: “environment that can cause a dangerous action”, “unsafe environment”, and “sickroom as a living space”. There were four categories of risk factors related to “the student”: “students’ own physical/mental condition”, “anxiety caused by pediatric nursing practice”, “learning process in nursing practice” and “students’ understanding of pediatric nursing”. The students recognized that there were various risk factors in the child, the family, and the environment, and, by the P-mSHELL model, they recognized that they themselves could become a risk factor. Based on the risk factors that students extracted, teachers should think about what kind of preparation is necessary for students in pediatric nursing practice, and it is important to conduct medical safety education.
