Juvenile idiopathic arthritis (JIA) is the most common arthritis in the adolescents under the age of 16. Etanercept, an inhibitor of tumor necrosis factor, is often used to treat JIA despite its significant side effects. Homeopathic remedies, such as blueberries, have anti-inflammatory properties with fewer unwanted effects and should be considered as a primary treatment. We aimed to explore the efficacy and safety of combination therapy of blueberry and etanercept for JIA. Two hundred and one JIA patients were selected, and randomly and evenly assigned to three groups: ETA (50 mg of etanercept twice weekly), ETABJ (matched etanercept and 50 ml blueberry juice daily) and ETAPJ (matched etanercept and placebo juice). The severity of JIA was measured using American College of Rheumatology scales (ACR) 20, 50 and 70. The levels of pro-inflammatory cytokines, interleukin-1 (IL1) alpha and IL1 beta, and interleukin-1 receptor antagonist (IL1RA) were measured by qRT-PCR and ELISA. After a 6-month follow-up, the ACR20, ACR50 and ACR70 in an ETABJ group were higher than those in other two groups (P < 0.05), suggesting clinically meaningful improvement in JIA. Meanwhile, the symptoms and side effects were reduced significantly or absent in an ETABJ group, including mental diseases, retrobulbar optic neuritis, gaining weight, infection, cutaneous vasculitis, diarrhea, uveitis and pancytopenia. Blueberries reduced the levels of IL1 alpha and beta, and increased the level of IL1RA. Thus, a combination therapy of blueberry and etanercept can reduce the severity of JIA and should be developed as a new method for JIA therapy.

A retrospective analysis was carried out on 93 patients with signet ring cell carcinoma of the stomach operated on between 1985 and 1995, to review the clinicopathologic characteristics from the database of gastric cancer at Sendai National Hospital. The results were compared with those for 590 patients with other types of gastric carcinoma. Women were afflicted as commonly as men in the signet ring cell carcinoma group. These patients tended to be younger and to have larger tumors. The histological type was commonly scirrhous and infiltrative. The survival of patients with signet ring cell carcinoma was worse than that of patients with other types of gastric cancer but the difference was not statistically significant. Patients with early signet ring cell carcinoma had a good prognosis, similar to that of the other groups. However, prognosis of patients with advanced signet ring cell carcinoma was poor compared with patients with other types of this disease. In multivariate analysis, the statistical significant prognostic factors were vascular microinvasion and tumor location. These findings suggest that signet ring cell carcinoma of the stomach should be regarded as a distinct type of gastric cancer.

Many countries in Europe and the world have to cope with an aging population. Although health policy in many countries aims at increasing disability-free life expectancy, elderly patients represent a significant proportion of all patients admitted to different hospital departments. The aim of the research was to investigate the relationship between health-related quality of life (HRQOL) and the care dependency status among elderly hospital patients. In 2012, a descriptive survey was administered to a convenience sample of 325 elderly hospital patients (> 60 years) from The Netherlands (N = 125), from Poland (N = 100), and from Turkey (N = 100). We employed the Functional Assessment of Chronic Illness Therapy (FACIT) Measurement System and the Care Dependency Scale. FACIT is a collection of HRQOL questionnaires that assess multidimensional health status in people with various chronic illnesses. From demographic variables, gender (female) (r = −0.13, p < 0.05), age and informal care given by family members (r = −0.27 to 0.27, p < 0.01) were significantly correlated with the care dependency status for the whole samples. All HRQOL variables, hearing aid and duration of illness correlated with care dependency status (r = −0.20 to 0.50, p < 0.01). Moreover, the FACIT sum score (Poland and Turkey) and functional wellbeing (The Netherlands) are significantly associated with the decrease in care dependency status. Thus, the FACIT variables are the most powerful indicators for care dependency. The study provides healthcare professionals insight into improvement of quality of care in all three countries.

On March 11, 2011, the Great East Japan Earthquake devastated the Tohoku region, which led to a tsunami and a nuclear disaster. While these three disasters caused tremendous physical damage, their psychological impact remains unclear. The present study evaluated traumatic responses, internalizing (i.e., anxiety and depression), and externalizing (i.e., anger) symptoms among Japanese young people in the immediate aftermath and 2.5 years later. A total of 435 undergraduates were recruited from universities in three differentially exposed regions: Fukushima, Tokyo, and Kyoto. They completed a set of questionnaires retrospectively (i.e., September to December 2013) to measure their traumatic responses, anxiety and depressive symptoms, functional impairment, and anger immediately after the disaster and 2.5 years later. Participants in Tokyo had the highest level of traumatic response and internalizing symptoms immediately after the earthquake, whereas those in Fukushima had significantly higher levels of trait anger, anger-in (holding one’s anger in), and anger-out (expressing one’s anger externally). In Kyoto, the levels of anxiety and depression after 2.5 years were significantly higher than they were immediately after the disasters. In conclusion, anger symptoms were high among young people who lived at or near the center of the disasters, while anxiety and depression were high among those who lived far away from the disasters. These findings suggest the importance of providing mental health services to young people who did not live near the disaster area as well as to those living in the directly affected area.

Owing to the reduced capacity for information processing following a stroke, patients commonly present with difficulties in performing activities of daily living that combine two or more tasks. To address this problem, in the present study, we investigated the effects of neurofeedback training on the abilities of stroke patients to perform dual motor tasks. We randomly assigned 20 patients who had sustained a stroke within the preceding 6 months to either a pseudo-neurofeedback (n = 10) or neurofeedback (n = 10) group. Both groups participated in a general exercise intervention for 8 weeks, three times a week for 30 min per session, under the same conditions. An electrode was secured to the scalp over the region of the central lobe (Cz), in compliance with the International 10-20 System. The electrode was inactive for the pseudo-training group. Participants in the neurofeedback training group received the 30-min neurofeedback training per session for reinforcing the sensorimotor rhythm. Electroencephalographic activity of the two groups was compared. In addition, selected parameters of gait (velocity, cadence [step/min], stance phase [%], and foot pressure) were analyzed using a 10-m walk test, attention-demanding task, walk task and quantified by the SmartStep system. The neurofeedback group showed significantly improved the regulation of the sensorimotor rhythm (p < 0.001) and ability to execute dual tasks (p < 0.01). Significant improvements on selected gait parameters (velocity and cadence; p < 0.05) were also observed. We thus propose that the neurofeedback training is effective to improve the dual-task performance in stroke patients.

Med., 1992, 166 (4), 475-477-A cohort study aimed to evaluate the effect of drinking green tea on longevity was performed. Three thousand three hundred and eighty female practitioners of chanoyu (Japanese tea-ceremony), living in Tokyo, were followed from 1980 to 1988, and 280 were dead during this period. Standardized mortality ratios were estimated 0.55 when all Japanese women was used as standard population and 0.57 when women living in Tokyo was used, indicating the possibility that green tea is a protective factor for several fatal diseases.

Early detection and optimal treatment are the most effective means to improve cancer mortality. Mass screening for cancer has yielded a marked reduction of cancer mortality in the United States. Simple and effective methods are expected for screening of malignancy. Hematoporphyrin derivatives (HPDs) are known to accumulate in cancer cells; thus, HPD has been used for local diagnosis and photodynamic therapy of cancer. The lymphocytes of cancer patients also demonstrate the active uptake of HPD and this phenomenon has been applied for the diagnosis of cancer. In the present study, we have developed a novel method for measurement of the chemiluminescence of HPD in peripheral blood lymphocytes. HPD is composed of hematoporphyrin and its oligomers. Seven cancer patients and seven controls were recruited for this study. The primary cancers included two prostate cancers (one without metastasis and the other with lung metastasis), a renal cancer, a lung adenocarcinoma with systemic metastasis, two gallbladder cancers with lung metastasis, and a colon cancer with liver metastasis. HPD in lymphocytes was measured using a highly sensitive chemiluminescence analyzer with laser light irradiation to detect photoemission by 1O2 from HPD. The intensity of chemiluminescence exhibited a linear correlation with the concentrations of HPD. In addition, the level of HPD in lymphocytes was significantly higher in cancer patients than that in healthy volunteers (p < 0.05). These results suggest that detection of the chemiluminescence of HPD in lymphocytes could be a sensitive and simple method for cancer diagnosis and screening.

Maternal undernutrition can affect offspring’s physical status and various health parameters that might be transmittable across several generations. Many studies have focused on undernutrition throughout pregnancy, whereas maternal undernutrition prior to pregnancy is not sufficiently studied. The objective of our study was to explore the effects of food restriction prior to and during pregnancy on body weight and longevity of the second generation offspring. Adult female Wistar rats (“F0” generation) were 50% food restricted for one month prior to pregnancy (pre-pregnancy) or during pre-pregnancy and pregnancy. The third group was fed normally (control). The first generation offspring were normally fed until the 6th month of age to produce the second generation offspring; namely, the first-generation female rats were mated with male breeders from outside the experiment. The second generation offspring thus obtained were observed until natural death (up to 36 months). Compared to the controls, the second-generation male offspring whose “grandmothers (F0 females)” undernourished only during pre-pregnancy were significantly heavier from the 8th month of age, whereas no significant weight difference was found in the male offspring whose “grandmothers” were food-restricted during pre-pregnancy and pregnancy. Shorter lifespan was observed in the second-generation male offspring of “grandmothers” that were food-restricted either during pre-pregnancy or during pre-pregnancy and pregnancy. By contrast, no differences in body weight and lifespan were observed in all second-generation female offspring. In conclusion, maternal caloric restriction prior to pregnancy increases the body weight and shortens the longevity of the second-generation male offspring, indicating the sex-dependent transgenerational effect of maternal caloric restriction.

Air pollution in Japan caused respiratory disease, such as chronic bronchitis and asthma, in many individuals in the 1960s. Although air pollution has decreased, many victims of air pollution-related respiratory disease are limited in their activities of daily living because of respiratory symptoms. The purpose of this study was to evaluate the efficacy of pulmonary rehabilitation in victims of air pollution-related chronic bronchitis or asthma. Subjects were enrolled in a 12-week (2-week inpatient followed by 10-week outpatient) pulmonary rehabilitation program. The program comprised conditioning, strength training, endurance training, and patient education. We assessed the Modified Medical Research Council (MMRC) dyspnea grade, pulmonary function, peripheral muscle force, incremental shuttle walk distance (ISWD), and physical activity at baseline and immediately after the program. Twenty-nine subjects (mean age 74.2 ± 10.1 years, 11 males) completed the program, including 11 subjects with COPD and 18 subjects with asthma. Following rehabilitation, the participants (n = 29) showed significant improvements in MMRC dyspnea grade, vital capacity % predicted, quadriceps force and ISWD (all P < 0.05). Sub-group analyses revealed that all these variables were significantly improved in subjects with asthma. In contrast, subjects with COPD showed significant improvements only in quadriceps force and ISWD (both P < 0.05). Thus, pulmonary rehabilitation is an effective method of improving exercise capacity and dyspnea in officially acknowledged victims of air pollution-related asthma. In conclusion, we recommend that patients with chronic bronchitis or asthma, resulting from exposure to air pollution, are referred for pulmonary rehabilitation.

Artrial fibrillation is the most common arrhythmia that occurs after coronary bypass grafting operation with the rate of 30%. Atrial fibrillation is associated with hemodynamic instability, strokes, and prolonged hospital stay. Pericardial effusion is a risk factor for atrial fibrillation after cardiac surgery, and it occurs commonly in the posterior area during the post-operative period. The aim of this prospective study was to demonstrate the effectiveness of posterior pericardiotomy in reducing the incidence of atrial fibrillation. This prospective randomized study was carried out on 425 patients undergoing a coronary artery bypass grafting in our clinic between August 2009 and February 2011. There were 276 male patients and 149 female patients. These patients were randomly divided into two groups; posterior pericardial incision was performed in 213 patients (pericardiotomy group), while any pericardial incision was not performed in 212 patients (control group). Atrial fibrillation occurred more frequently in control group (62 patients, 14.6%), compared to the pericardiotomy group (14 patients, 3.1%; p < 0.0001). The incidences of early pericardial effusion, late pericardial effusion, and tamponade were also significantly higher in control group. Moreover, posterior pericardiotomy was associated with the decreases in the duration of stay in hospital and intensive care unit. In fact, the total hospital costs were lower in the pericardiotomy group. In conclusion, posterior pericardiotomy is an effective and safe technique that reduces early pericardial effusion, atrial fibrillation, length of stay in hospital, and hospital costs after the coronary artery bypasses grafting.

A child with acute disseminated encephalomyelitis (ADEM) developed after acute herpetic gingivostomatisis was described. Inspite of the improvement of his gingivostomatitis, his consciousness gradually deteriorated and he was admitted to Nakadori General Hospital. His consciousness level was drowsiness and increased bilateral patellar reflexes were shown. Because magnetic resonance imaging (MRI) T2-weighted scan showed areas of high signal intensity disseminated in superior portion of medulla oblongata, dorsal portion of pons, basal nuclei and thalamus, he was suspected as having ADEM. Anti-herpes simplex virus (HSV) 1 IgG and IgM antibodies elevated in both blood and cerebrospinal fluid. From these results, HSV1 infection was thought to be the preceding infection of ADEM. Methylprednisolone therapy (20 mg/kg daily) for 3 days, followed by prednisolone (2 mg/kg) was started, with an excellent response. In addition, administration of acyclovir was also continued, considering the complication of HSV encephalitis. MRI T2-weighted scan performed at 2 months later after the onset of ADEM revealed disappearance of the lesions. He was discharged without remaining disorders. It is difficult to distinguish between ADEM and HSV encephalitis because both of these diseases show various neurological symptoms. In our case, MRI was the most useful method for correct diagnosis of ADEM. We concluded that ADEM is important as a disease of central nervus system due to HSV1 infection, in addition to encephalitis.

Neonatal jaundice is a common physiological problem affecting over half of all full term and most preterm infants. Thus, newborn infants must be monitored for signs of hyperbilirubinemia to prevent acute bilirubin encephalopathy or kernicterus. Evidence exists supporting the benefits of baby massage as a form of mild hand to skin contact, to increase neonatal physical and mental development. In the present study, the effects of gentle baby massage on neonatal jaundice in full term newborn infants were evaluated by a controlled clinical trial. The inclusion criteria of newborn neonates were as follows: (1) gestational age of 37 ~ 41 weeks, (2) birth weight of 2,800 ~ 3,600 g, (3) Apgar score at birth of 8 ~ 10, and (4) being a healthy neonate without neonatal asphyxia and hemolytic condition. Breastfed newborns without phototherapy were included: 20 in the massage group and 22 in the control group. We found the mean stool frequency of the massaged infants on day 1 and day 2 (4.6 and 4.3) was significantly higher than that of the control group (3.3 and 2.6) (p < 0.05). The transcutaneous bilirubin levels on the second to fifth day and serum total bilirubin levels on fourth day were significantly decreased in the massage group, compared to the control group. In conclusion, baby massage at an early stage after birth could reduce neonatal bilirubin levels. We suggest baby massage is beneficial for ameliorating neonatal jaundice.

Vertebral fractures are an under-recognized problem in children with glucocorticoid-induced osteoporosis (GIO). They cause severe back pain and spinal column deformity with a decrease of quality of life. For evaluating the bone mass, bone mineral density measurements have been widely carried out using dual energy X-ray absorptiometry. However, bone histomorphometric analyses of GIO in children are scarce. Bone histomorphometric analyses of vertebral bodies have not been reported. Our aim is to report the first bone histomorphometric data for vertebrae from an autopsied child with GIO. A 15-year-old girl with systemic lupus erythematosus was started on a daily oral dose of 10 mg of prednisolone at 6 years of age. She presented with back pain from 12 years of age. Magnetic resonance imaging at 14 years of age showed a compression fracture of the first lumbar (L1) vertebral body. At 15 years of age, she died of heart failure owing to pulmonary hypertension. Collapsed (L1) and non-collapsed (seventh thoracic vertebrae; T7) vertebral bodies were autopsied for bone histomorphometry and compared. T7 showed severe osteoporosis (bone volume, 4.99%; trabecular thickness, 59 μm; trabecular separation, 1,134 μm). Compared with T7, L1 showed increased bone volume (33.9%) and trabecular thickness (77 μm), and decreased trabecular separation (156 μm) owing to the impact of the vertebral fracture. The bone formation and bone resorption parameters were comparable between the two vertebrae. These histological findings suggest that severe osteoporosis developed after long-term glucocorticoid administration, and that the remodeling activities were similar in the fractured and non-fractured vertebrae.

Regular physical activity is associated with improvements of metabolic syndrome (MetS) risk factors. Furthermore, recent physical activity guidelines for health promotion recommend that moderate to vigorous physical activity should be performed in bouts lasting ≥ 10 min. Brisk walking is a popular and readily attainable form of moderate intensity physical activity and is suitable for the majority of individuals. However, it is unclear whether brisk walking lasting ≥ 10 min is associated with improvement in MetS. This study aimed to determine the effects of a 1-year lifestyle-based physical activity intervention with brisk walking of ≥ 10 min using a pedometer on the improvement in MetS. Three hundred and seventy-six overweight male employees with ≥ 1 MetS component(s) participated in this intervention study from 2008 to 2009 (age, 30-62 years; body mass index, 23.0-45.5 kg/m2). Overall, 316 participants (84%) completed the 1-year intervention. MetS was defined according to the Japanese criteria at baseline and after 1 year. Brisk walking lasting ≥ 10 min was significantly associated with the decrease in waist circumference (β = −1.479) and triglyceride (β = −31.260), and the increase in high-density lipoprotein cholesterol (β = 2.117). The brisk walking step counts were also significantly associated with higher odds for an improvement in MetS (OR, 1.48; 95% CI, 1.05-2.09) and abdominal obesity (OR, 1.45; 95% CI, 1.12-1.87). In conclusion, the lifestyle-based intervention with brisk walking of ≥ 10 min is an effective strategy to improve MetS in overweight male employees.

Headache is one of the most common neurological complaints of the young population and it affects the quality of life due to limitation of daily activities. In this study, our main goal was to appraise the general headache characteristics in senior medical students just before graduation and to determine the impact of headache on the quality of life, as well as the general attitude of students about their headaches. The study group consisted of 141 senior students. As the first step, the question about “having headache within the past one year period” was asked. Of the 141 students, 127 students answering “yes” were invited to a face-to-face interview. Of these, 67 students (52.8%) participated in the second evaluation. The second evaluation consisted of history taking and neurological and physical examination. All subjects were classified according to the International Classification of Headache Disorders (2nd edition) criteria. Validated Turkish version of Migraine Disability Assessment questionnaire was given to the subjects to evaluate the socio-economical impact of headache. Tension-type headache, which is the most common form of primary headaches, was identified in 34 students (50.7%) out of 67 students. Migraine was detected in 31 students (46.3%). This is the first study performed on a face-to-face interview basis with medical students using the new classification criteria in Turkey. Astonishingly, most of the students (n:65) ignored their headaches and did not seek medication, despite the negative impact of headache on daily functioning and overall quality of life.

Bei der Elektrenkephalographie des Menschen lässt sich eine von den eigentlichen Hirnströmen sicher unterscheidbare langsame Schwankung auf Augenbelichtung hin nachweisen. Da sie detn bei Tieren gefundenen “On”-Effekt der optischen Hirnrinde etwas ähnlich ist, wurde sie ohne weiteres der Grosshirnrinde zugeschrieben. Angesichts ihres mit dem cerebralen “On”-Effekt bei Tieren nicht ganz übereinstimmenden Verhaltens wurde ihre vermeintliche Herkunft in Zweifel gezogen und folgende Untersuchung angestellt, um das Wesen dieser Potentialschwankung aufzuklären: 1. Sie ist von Lid- und Augenbewegungen unabhängig, was mit der elektrischen Registriermethode der Lid- und Augenbewegungen einwandfrei nachgewiesen wurde. 2. Ein rotes Licht ist weniger wirksam als ein weisses oder ein blaues, um diese Schwankung hervorzurufen. 3. Durch Untersuchungen über die Potentialverteilung auf dem Kopf wurde festgestellt, dass diese Schwankung von den Augen oder wenigstens von ihrer Nähe herruhrt. 4. Der naturgetreue Verlauf dieser Schwankung wurde mittels eines Gleichstromverstärkers und eines Oszillographen registriert, um festzustellen, dass sie in jeder Hinsicht mit dem Elektroretinogramm des Menschen iibereinstimmt. 5. Auf rhythmische optische Reize lassen sich in Bestätigung des Adrian schen Befunds periodische Schwankungen des Potentials nachweisen. Das Bild and andere Eigenschaften dieser Flickerantwort sind auf der vorderen and der hinteren Hälfte des Kopfes sehr verschieden, indem Netzhautprozess beim ersteren Fall eine überwiegende Rolle spielt. Es sei nachdrücklich betont, lass sich der Belichtungsstrom der Netzhaut bei der Elektrenkephalographie unter Umständen geltend macht, um eine Konfusion mit Hirnströmen hervorzurufen, besonders wenn eine Elektrode in der Nähe der Augen liegt.

Patients with renal failure undergoing hemodialysis often have muscle cramps during and after the dialysis therapy. Muscle cramps are defined as the sudden onset of a prolonged involuntary muscle contraction accompanied with severe pain, resulting in early termination of a HD session and inadequate dialysis. The etiology of the cramps is unknown and effective anti-cramp medicine is not available. We have hypothesized that water-soluble vitamins are deficient in HD patients. Accordingly, we administrated biotin to 14 patients who had frequent muscle cramps during HD sessions. Oral administration of 1 mg/day biotin promptly reduced the onset and the severity of cramps in 12 patients both during and after HD. Then, the plasma biotin levels were measured by an enzyme-linked immunosorbent assay method (ELISA) in HD patients, including 14 patients with cramps and 13 patients without cramps, and 11 healthy volunteers. Plasma biotin levels were elevated in 27 HD patients at baseline compared with healthy volunteers [451 (377 - 649) vs. 224 (148 - 308) ng/l, median (lower-upper quartiles); p < 0.0001]. Unexpectedly, among the 14 cramp patients, the biotin levels were significantly higher in biotin-ineffective 7 patients than biotin-effective 7 patients [1,064 (710 - 1,187) vs. 445 (359 - 476) ng/l; p < 0.001]. Thus, the biotins measured by ELISA may consist of not only intact biotin but also its metabolites that do not function as a vitamin. In conclusion, biotin administration is one choice to relieve HD patients from muscle cramps regardless of their elevated plasma biotin levels.

Pneumonia is not only a major cause of death for elderly persons, but also imposes substantial personal morbidity and burdens on the health care system. An understanding of the pathogenesis of this serious illness could allow us to devise methods for curbing the incidence and severity of the disease. Pathophysiological issues and preventative measures are the subject of this review.

Revaprazan is the first acid pump antagonist with a function similar to that of proton pump inhibitors (PPIs). It has a dual action, active suppression of gastric acid secretion and gastric mucosa protection. While PPIs are known to enhance the prolongation of prothrombin time by warfarin, no research has been done on the drug interaction between revaprazan and warfarin. This study was conducted in order to verify the potential drug interaction between revaprazan and warfarin. Omeprazole, a representative PPI, was used as the control for revaprazan. We searched for patients who were given either revaprazan or omeprazole along with warfarin using the medical record database of Seoul National University Hospital between July 2007 and June 2010. Among the 15 patients who took revaprazan and warfarin together, 73.3% (11/15) showed more than 30% reduction of anticoagulation effect by warfarin after revaprazan was added. The revaprazan group showed a significant shortening of prothrombin time during revaprazan administration compared to pre- and post-revaprazan medication (P < 0.05) while the omeprazole group did not show such difference. Revaprazan seems to have cumulative dose-dependent anti-warfarin or anti-coagulation effect, as judged from the fact that the longer medication with revaprazan showed correlation with the shortening of prothrombin time (R = −0.632, P < 0.05). This study shows a possible interaction between revaprazan and warfarin and suggests that revaprazan can cause shortening of prothrombin time. Therefore, when revaprazan is prescribed to patients on warfarin therapy, prothrombin time should be frequently monitored.
