Abstract
The gut microbiota was reported to differ between children with autism spectrum disorder (ASD) and typically developing (TD) children, and dysbiosis of the gut microbiota in preterm infants is common. Here, we explored the characteristics of gut microbiota in children born preterm with ASD. We performed 16S rRNA gene sequencing using stool samples from ASD children born preterm and TD children born preterm. Alpha diversity was significantly greater in the ASD group. A comparison of beta diversity showed different clusters. Linear discriminant analysis effect size analysis revealed significantly more Firmicutes in the ASD group compared with the TD group. In conclusion, the gut microbiota in children born preterm differs between children with ASD and TD.

Efficacious interventions for improving the transition readiness of adolescents and young adult patients with chronic illness: A narrative review of randomized control trials assessed with the transition readiness assessment questionnaire. Front Pediatr 2022; 10:983367. [PMID: 36245732 PMCID: PMC9554476 DOI: 10.3389/fped.2022.983367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 09/05/2022] [Indexed: 11/29/2022] Open
Abstract
Objective We inspected efficacious interventions to improve the transition readiness of adolescent and young adult patients with childhood-onset chronic illnesses using the Transition Readiness Assessment Questionnaire (TRAQ). Methods Our narrative review was conducted on randomized control studies assessed with TRAQ for outcome measurement before and after the interventions. We included all patients with chronic diseases. We searched eight electronic database(s): Allied and Complementary Medicine Database (AMED) Allied and Complementary Medicine, BioSciences Information Service of Biological Abstracts (BIOSIS) Previews, Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, Embase, Ichu-shi, Medline, and Web of Science. The text words for the search of data sources were as follows: "("transition readiness assessment questionnaire" OR TRAQ) AND 2011/01:2022/06[DP] AND (clinical AND trial OR clinical trials OR clinical trial OR random* OR random allocation)." More studies were identified from the references in our reported study. This data set was independently cross-checked by two reviewers. Results We identified 261 reports and collected three articles. The target diseases were type-1 diabetes, congenital heart disease, cystic fibrosis, and inflammatory bowel disease. All the studies excluded patients with intellectual disabilities. The age of the participants was distributed between 12 and 20 years. Nurse-provided web-based intervention of transition readiness was constructed using digital resources in two studies. The intervention ranged from 6 to 18 months. All the interventions were efficacious in improving transition readiness assessed with TRAQ scores, except for the self-advocacy score. Conclusions We obtained three randomized control studies with TRAQ for outcome measurement. In two studies, web-based and nurse-led organized interventions were shown to improve transition readiness.

Factors Surrounding the Healthcare Transition From Pediatric to Adult Care in 5p- Syndrome: A Survey Among Healthcare Professionals. Front Pediatr 2022; 10:924343. [PMID: 35874599 PMCID: PMC9304764 DOI: 10.3389/fped.2022.924343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 06/21/2022] [Indexed: 12/03/2022] Open
Abstract
Background The 5p- syndrome is associated with intellectual disturbance and physical complications from infancy, and patients continue treatment into adulthood. This study aimed to clarify the factors that facilitate and prevent healthcare transition from pediatric to adult care by conducting a questionnaire survey among medical professionals. Subjects The survey included 81 medical professionals nominated by an association of families of 5p- patients in Japan. The questions involved medical care for 5p- syndrome in adulthood, experience of transition, and factors facilitating a patient's transition. Responses were obtained from 32 participants, with 27 answers eligible for analysis. Results The questionnaire items involved physical symptoms and concerns regarding support and welfare prompting consult. The most common physical symptom was constipation. Regarding support and welfare, all participants had an experience of receiving consultation about care for the siblings of patients. Three (11.1%) participants had an experience of transition. Regarding the transition of patients with rare diseases or intellectual disturbance, only four (14.8%) believed that progress was being made in the transition. Discussion Only 11% of the respondents experienced the transition of patients with 5p- syndrome. Because it is difficult for highly specialized adult care providers to deal with multidisciplinary complications of 5p- syndrome and information on prognosis and natural history is not known, it is presumed that the transition of 5p- syndrome did not progress. Factors to improve the transition of patients with 5p- syndrome and are likely to be effective for the transition of patients with other rare diseases or intellectual disabilities.

Psychogenic fever and postural tachycardia syndrome among school-aged children and adolescents with fever of unknown origin. Biopsychosoc Med 2022; 16:9. [PMID: 35351159 PMCID: PMC8962125 DOI: 10.1186/s13030-022-00238-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Accepted: 03/16/2022] [Indexed: 11/29/2022] Open
Abstract
Background Although fever is a common symptom in pediatric practice, its origin is often unknown in pediatric patients. Psychogenic fever is a stress-related, psychosomatic disease observed especially in young women. This study aimed to estimate the prevalence of psychogenic fever in pediatric patients with fever of unknown origin by surveying the medical records of school-aged children and adolescents. Methods The study subjects included 47 patients aged 6–15 years who visited the Department of Pediatrics in Kansai Medical University Medical Center between January 2006 and December 2020 with fever of unknown origin. Data on age, sex, final estimated diagnosis, and comorbid psychosocial issues were collected from the medical records. Results The study was composed of 47 patients, including 22 male and 25 female patients (male/female ratio, 1:1.36). The mean age was 10.1 (standard deviation, 2.4) years for boys and 11.6 (standard deviation, 2.7) years for girls (p = .047). The final estimated diagnoses were psychogenic fever, physical disorder, infection of unknown origin, and miscellaneous in 18, 12, 12, and 5 patients, respectively. The most common comorbidity in these pediatric patients with psychogenic fever was postural tachycardia syndrome. Conclusion Psychogenic fever was a common cause of fever of unknown origin in pediatric patients, and postural tachycardia was prevalent among children with psychogenic fever. Enhanced sympathetic response to stress might play an important role in both psychogenic fever and postural tachycardia.

Eye gaze differences in school scenes between preschool children and adolescents with high-functioning autism spectrum disorder and those with typical development. Biopsychosoc Med 2021; 15:2. [PMID: 33461582 PMCID: PMC7814533 DOI: 10.1186/s13030-020-00203-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 11/26/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Children with autism spectrum disorder (ASD) may experience difficulty adapting to daily life in a preschool or school settings and are likely to develop psychosomatic symptoms. For a better understanding of the difficulties experienced daily by preschool children and adolescents with ASD, this study investigated differences in eye gaze behavior in the classroom environment between children with ASD and those with typical development (TD). METHODS The study evaluated 30 children with ASD and 49 children with TD. Participants were presented with images of a human face and a classroom scene. While they gazed at specific regions of visual stimuli, eye tracking with an iView X system was used to evaluate and compare the duration of gaze time between the two groups. RESULTS Compared with preschool children with TD, preschool children with ASD spent less time gazing at the eyes of the human face and the object at which the teacher pointed in the classroom image. Preschool children with TD who had no classroom experience tended to look at the object the teacher pointed at in the classroom image. CONCLUSION Children with ASD did not look at the human eyes in the facial image or the object pointed at in the classroom image, which may indicate their inability to analyze situations, understand instruction in a classroom, or act appropriately in a group. This suggests that this gaze behavior of children with ASD causes social maladaptation and psychosomatic symptoms. A therapeutic approach that focuses on joint attention is desirable for improving the ability of children with ASD to adapt to their social environment.

Abstract
Abdominal ultrasonographical and computed tomography examinations of a 12-year-old neutered female toy poodle revealed a protruding mass, approximately 2 cm in diameter, at the apex of the bladder. The mass was firm and haemorrhagic with a homogeneously brownish-yellow cut surface. Microscopically, it was unencapsulated and located in the muscle layer with invasion of the extra-muscular layer. It was composed of spindloid to oval neoplastic cells that formed irregular clefts and diffuse sheets that dissected bundles of collagen. Immunohistochemically, the neoplastic cells were positive for vimentin and lymphatic vessel endothelial hyaluronan receptor 1 antigens, but negative for cytokeratin AE1/AE3, factor VIII-related antigen, CD31, CD34, Prox-1, S100, desmin, α-smooth muscle actin and MyoD1. Negative immunolabelling for laminin antigen supported the absence of evidence of a basal lamina on ultrastructural examination. Based on these findings, this tumour was identified as a lymphangiosarcoma. To the best of our knowledge, this case is the first report of lymphangiosarcoma arising from the bladder in a dog.

Association between dexamethasone treatment and alterations in serum concentrations of trace metals. DIE PHARMAZIE 2020; 75:218-222.

Abstract
Previously, a significant elevation in the serum levels of iron (Fe) was observed within a few days after the initiation of cisplatin (CDDP)-based chemotherapy. To clarify the underlying mechanisms, the serum concentration of hepcidin, a negative regulator of Fe release, was determined in the clinical samples obtained from six patients with cancer. The result showed that the serum concentration of hepcidin in patients receiving CDDP-based chemotherapy was significantly increased after 4-6 days of treatment, in comparison to the baseline level, suggesting that aforementioned excessive systemic Fe was not explained by the change of serum hepcidin level. All these patients received antiemetic premedication. We next evaluated of the effects of Pt-containing drugs and prophylactic antiemetic dexamethasone medication on the serum concentration of trace metals in mice, and on the hepatic and renal concentration of trace metals. The serum concentrations of Fe, Cu, and Zn in the CDDP-treated and oxaliplatin-treated mice were not significantly altered in comparison to those of the vehicle-treated control group. The serum concentrations of Fe, Cu, and Zn were increased after 24 h of dexamethasone treatment, compared to those of the control group (P < 0.05). The hepatic concentration of Mn was significantly reduced, whereas those of Fe and Cu inclined to diminish. The present findings suggest that dexamethasone can partly contribute to the changes in the serum concentrations of trace metals during anticancer chemotherapy.

Abstract
Human papillomavirus vaccination (HPVV) was included in the national immunization program in 2013 in Japan. However, the Japanese government suspended proactive recommendations 2 months after this decision because various adverse events following the vaccination were reported by the media. More than 6 years have already passed since the suspension of proactive recommendations of all available vaccines in Japan. Although no causal relationship between the adverse effects and HPVV has been confirmed, the Japanese government has not withdrawn the suspension. Thus, it is important to show various possible causes of the adverse events other than HPVV. It is attempted to describe the possible contribution of the misunderstanding regarding the symptoms of postural tachycardia syndrome, deconditioning, and exercise-induced hyperalgesia as the adverse effects of HPVV in this review article.

Abstract
BACKGROUND For patients with childhood-onset chronic illnesses, the transition to adult care requires an understanding of transition readiness and the effectiveness of evaluation methods. However, no such psychometrically verified scales exist in Japan. This study aimed to develop a Japanese version of the Transition Readiness Assessment Questionnaire (TRAQ) and verify its validity and reliability. METHODS The Japanese TRAQ was developed in accordance with international guidelines, followed by a preliminary survey to verify face validity among six participants who fulfilled the inclusion criteria. For the main survey 107 patients who fulfilled the same inclusion criteria were asked to complete the questionnaire and provide basic information. After descriptive statistics analysis, the construct validity of the Japanese TRAQ was tested using the t-test and Pearson's correlation coefficients. Cronbach's alpha coefficients were calculated to assess reliability. RESULTS In the main survey, 76 participants with no missing data were included in the complete data analysis (40 males 36 females; mean age, 17.8 and 18.2 years, respectively). The mean total Japanese TRAQ score was 3.9. Cronbach's alpha coefficients were 0.94 overall and 0.8-0.96 for each of the four domains. The known-groups analysis revealed that older participants (r = 0.23, P = 0.044), those having knowledge of the disease name (yes [4.0] vs no [3.4]; P < 0.001), and making unaccompanied hospital visits (with parent/others [3.7] vs alone [4.4]; P < 0.001) had significantly higher total TRAQ scores. CONCLUSION We confirmed preliminarily the validity and reliability of the Japanese TRAQ.

Abstract
Children with autism spectrum disorders (ASD) who have neurodevelopmental impairments in social communication often refuse to go to school because of difficulties in learning in class. The exact cause of maladaptation to school in such children is unknown. We hypothesized that these children have difficulty in paying attention to objects at which teachers are pointing. We performed gaze behavior analysis of children with ASD to understand their difficulties in the classroom. The subjects were 26 children with ASD (19 boys and 7 girls; mean age, 8.6 years) and 27 age-matched children with typical development (TD) (14 boys and 13 girls; mean age, 8.2 years). We measured eye movements of the children while they performed free viewing of two movies depicting actual classes: a Japanese class in which a teacher pointed at cartoon characters and an arithmetic class in which the teacher pointed at geometric figures. In the analysis, we defined the regions of interest (ROIs) as the teacher’s face and finger, the cartoon characters and geometric figures at which the teacher pointed, and the classroom wall that contained no objects. We then compared total gaze time for each ROI between the children with ASD and TD by two-way ANOVA. Children with ASD spent less gaze time on the cartoon characters pointed at by the teacher; they spent more gaze time on the wall in both classroom scenes. We could differentiate children with ASD from those with TD almost perfectly by the proportion of total gaze time that children with ASD spent looking at the wall. These results suggest that children with ASD do not follow the teacher’s instructions in class and persist in gazing at inappropriate visual areas such as walls. Thus, they may have difficulties in understanding content in class, leading to maladaptation to school.

Abstract
We evaluated the efficacy and safety of aripiprazole in the treatment of irritability in children and adolescents (6-17 years) with autism spectrum disorder (ASD) in a randomized, double-blind, placebo-controlled 8-week study in Japan. Patients received flexibly dosed aripiprazole (1-15 mg/day) or placebo. Ninety-two patients were randomized to placebo (n = 45) or aripiprazole (n = 47). Aripiprazole produced a significant improvement in the mean parent/caregiver-rated Aberrant Behavior Checklist Japanese Version irritability subscale score relative to placebo from week 3 through week 8. Administration of aripiprazole provided significantly greater improvement in the mean clinician-rated Clinical Global Impression-Improvement scores than placebo from week 2 through week 8. All patients randomized to aripiprazole completed the study, and no serious adverse events were reported. Three patients in placebo group discontinued. Aripiprazole was effective and generally safe and well-tolerated in the treatment of irritability associated with ASD in Japanese children and adolescents.

Abstract
OBJECTIVE To investigate the clinical and epidemiologic features of pediatric acquired demyelinating syndromes (ADS) of the CNS in Japan. METHODS We conducted a nationwide survey and collected clinical data on children with ADS aged 15 years or younger, who visited hospitals between 2005 and 2007. RESULTS Among 977 hospitals enrolled, 723 (74.0%) responded to our inquiries and reported a total of 439 patients as follows: 244 with acute disseminated encephalomyelitis (ADEM), 117 with multiple sclerosis (MS), 14 with neuromyelitis optica (NMO), and 64 with other ADS. We collected and analyzed detailed data from 204 cases, including those with ADEM (66), MS (58), and NMO (10). We observed the following: (1) the estimated annual incidence rate of pediatric ADEM in Japan was 0.40 per 100,000 children (95% confidence interval [CI], 0.34-0.46), with the lowest prevalence in the north; (2) the estimated prevalence rate of MS was 0.69 per 100,000 children (95% CI, 0.58-0.80), with the lowest prevalence in the south; (3) NMO in Japan was rare, with an estimated prevalence of 0.06 per 100,000 children (95% CI, 0.04-0.08); and (4) the sex ratio and mean age at onset varied by ADS type, and (5) male/female ratios correlated with ages at onset in each ADS group. CONCLUSIONS Our results clarify the characteristic clinical features of pediatric ADS in the Japanese population.

Abstract
To evaluate the effects of overseas sojourns on the psychosocial conditions of children, we observed Japanese children and their mothers temporarily living in the United States. Using a questionnaire, we examined the psychosocial condition of 61 Japanese mother-and child pairs (male = 51 percent, aged 8 to 15) living in the United States. One-fourth of the mothers were regarded as having minor psychiatric illness according to the General Health Questionnaire. One-tenth of the children were assessed as depressive by the Children’s Depression Inventory, and 30 percent of the children were identified as having a high level of anxiety according to the Children’s Manifest Anxiety Scale. Multiple regression analysis revealed that the mother’s minor psychiatric illness was significantly associated with the levels of depression and anxiety in their children.

Abstract
The transition of adult patients with childhood-onset chronic diseases (APCCD) from pediatric to adult health-care systems has recently received worldwide attention. However, Japan is lagging behind European countries and North America as this concept of health-care transition was introduced only 10 years ago. In Japan, before the introduction of this concept, APCCD were referred to as "carryover patients," who were often considered a burden in pediatric practice. In the late 1990s, groups composed of pediatric nephrologists, developmental and behavioral pediatricians, pediatric nurses, and special education teachers researching the quality of life of adult patients with chronic kidney disease began to discuss the physical and psychosocial problems of APCCD. In 2006, a group of pediatricians first introduced the term "transition" in a Japanese journal. By 2010, a group of adolescent nurses had begun a specialized training program aimed at supporting patients during the transitional period. In 2013, the Ministry of Health, Labour and Welfare in Japan convened a research committee, focusing on issues related to social, educational, and medical support for APCCD, and the Japan Pediatric Society established a committee for the health-care transition of APCCD and summarized their statements. Moreover, in 2013, the Tokyo Metropolitan Children's Medical Center initiated ambulatory services for APCCD managed by specialized nurses. The concept of health-care transition has rapidly spread over these past 10 years. The purpose of this article is to describe how this concept of health-care transition has advanced in Japan, such that APCCD now experience a positive pediatric to adult health-care transition.

Abstract
Background Advances in medical science have enabled many children with chronic diseases to survive to adulthood. The transition of adult patients with childhood-onset chronic diseases from pediatric to adult healthcare systems has received attention in Europe and the United States. We conducted a questionnaire survey among 41 pediatricians at pediatric hospitals and 24 nurses specializing in adolescent care to compare the perception of transition of care from pediatric to adult healthcare services for such patients. Findings Three-fourths of the pediatricians and all of the nurses reported that transition programs were necessary. A higher proportion of the nurses realized the necessity of transition and had already developed such programs. Both pediatricians and nurses reported that a network covering the transition from pediatric to adult healthcare services has not been established to date. Conclusions It has been suggested that spreading the importance of a transition program among pediatricians and developing a pediatric-adult healthcare network would contribute to the biopsychosocial well-being of adult patients with childhood-onset chronic disease.

Abstract
Chronic pain is a common problem in pediatric practice. The prevalence of chronic pain in children is >30%. Because pain indicates emotional expression as well as the physiological reaction toward infection, injury, and inflammation, both physiological and psychological assessments are essential to determine primary interventions for chronic pain. The Japanese Society of Psychosomatic Pediatrics Task Force of clinical practice guidelines for chronic pain in children and adolescents compiled clinical evidence and opinions of specialists associated with the primary care of pediatric chronic pain in the Japanese 'clinical guidelines for chronic pain in children and adolescents' in 2009, which are presented herein. The guidelines consist of three domains: general introduction to chronic pain; chronic abdominal pain; and chronic headache. Each section contains information on the physiological mechanism, psychological aspects, assessment methods, and primary interventions for pediatric chronic pain. These guidelines are expected to help disseminate knowledge on primary interventions for chronic pain in children and adolescents.

Abstract
A special consideration of psychotropic medication for children and adolescents in Japan is described. The use of all antidepressants and antianxiety drugs are "off-label". When using psychotropic drugs for the adolescents who complaint general fatigue, headache, or sleep disturbance, it should be confirmed the presence of the orthostatic disturbance (OD), because those drugs have the possibility of deteriorating the symptoms of OD. It is necessary to evaluate the risk and benefit for use of antidepressants in adolescents with major depression, considering the possibility of increasing suicide attempts. Long-acting methylphenidate and atomoxetine are regarded as the first line drugs for the treatment of children with attention deficit hyperactivity disorder. It is expected to solve "off-label" use and to establish clinical guidelines for the pharmacological treatment.

Brn-3b inhibits generation of amacrine cells by binding to and negatively regulating DLX1/2 in developing retina. Neuroscience 2011; 195:9-20. [PMID: 21875655 DOI: 10.1016/j.neuroscience.2011.08.015] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2011] [Revised: 08/03/2011] [Accepted: 08/03/2011] [Indexed: 02/03/2023]
Abstract
During retinogenesis, the basic helix-loop-helix proneural gene math5 (atoh7) initiates the generation of the first-born neurons, retinal ganglion cells (RGCs), by activating a network of RGC transcription factors, including Brn-3b (POU4F2). Herein, we show that the expression of DLX1 and DLX2 is significantly down-regulated in math5-null retina but is markedly increased in Brn-3b-null retina. Interestingly, Brn-3b interacts with DLX1 through its homeodomain, and this interaction represses DLX1 activity. Retrovirus-mediated mis-expression of DLX1 or DLX2 dramatically increases the number of amacrine/bipolar cells and concurrently reduces rod photoreceptors. Conversely, combined ectopic expression of Brn-3b with DLX1 or DLX2 promotes the production of RGCs and inhibits amacrine cell differentiation. Thus, DLX1/2 play an essential role in cell fate selection between amacrine and RGCs. Brn-3b suppresses the role of DLX1/2 through physical interaction and biases the competent precursors toward RGC fates.

Abstract
AIMS Orthostatic dysregulation (OD) is common in adolescents. This study was conducted to evaluate the usefulness of the measurement of the diameter of the inferior vena cava (IVC) for objective assessment of patients with OD. METHODS Twenty children with OD (median 14 years, range 9-15 years) and 23 age-matched healthy children (median 12 years, range 10-15 years) were enrolled. A diameter of IVC was measured by an abdominal echogram before and after a head-up tilt table testing (HUT). Changes in IVC was assessed by an arbitrary parameter, collapse index (CI) as the following equation: [(maximal IVC diameter in the supine position - maximal IVC diameter in the standing position)/(maximal IVC diameter in the supine position)]× 100. CI was evaluated 4 weeks after treatment with an adrenergic agent. RESULTS Children with OD demonstrated either higher CI or lower CI compared to that in control children: CI was more than 50 (range 50-71) in 12 patients with OD while that was equal to or less than 0 (range -225 to 0) in eight out of 20 patients. In contrast, CI was between 0 and 50 (range 1-26) in 23 healthy children. Pharmacological treatment induced the normalization in the CI in both higher and lower CI group. CONCLUSION OD can be classified into two subtypes: by HUT, one is characterized by an increase of IVC diameter while another is characterized by its decrease. Measurement of IVC diameter by HUT is useful to understand the pathophysiology and to assess the efficacy of treatment.

Abstract
In our sequential EEG study performed on 68 infants with various pre- and perinatal brain insults, we found peculiar abnormal fast activity (AFAs) in 12 patients. 9 of the 12 patients with AFAs later developed West syndrome (WS) compared with only 3 of the 56 patients without AFAs (p<0.001, χ(2) test). We analyzed these AFAs using EEG topography, and compared them with ictal fast activity (IFA) corresponding to tonic spasms observed later in the same patients after they had developed WS. We also investigated the clinical and EEG features in these patients. AFAs were first observed commonly at 4-5 months of CA, before the onset of WS. AFA topographic maps revealed posterior predominance in 11 of the 12 patients; IFA maps also showed posterior predominance but were more widely distributed. We propose that, though AFAs and IFAs are different, they share certain aspects of their pathophysiology, and that the maturational process of the occipital cortex plays an important role in the shared aspects. Since AFAs are observed before the onset of WS, they can be considered a sign that WS is imminent.

Abstract
BACKGROUND Although patients with liver cirrhosis are supposed to tolerate ischaemia-reperfusion poorly, the exact impact of intermittent inflow clamping during hepatic resection of cirrhotic compared with normal liver remains unclear. METHODS Intermittent Pringle's manoeuvre was applied during minor hepatectomy in 172 patients with a normal liver, 59 with chronic hepatitis and 97 with liver cirrhosis. To assess hepatic injury, delta (D)-aspartate aminotransferase (AST) and D-alanine aminotransferase (ALT) (maximum level minus preoperative level) were calculated. To evaluate postoperative liver function, postoperative levels of total bilirubin, albumin and cholinesterase (ChE), and prothrombin time were measured. RESULTS Significant correlations between D-AST or D-ALT and clamping time were found in each group. The regression coefficients of the regression lines for D-AST and D-ALT in patients with normal liver were significantly higher than those in patients with cirrhotic liver. Irrespective of whether clamping time was 45 min or less, or at least 60 min, D-AST and D-ALT were significantly lower in patients with cirrhosis than in those with a normal liver. Parameters of hepatic functional reserve, such as total bilirubin, prothrombin time, albumin and ChE, were impaired significantly after surgery in patients with a cirrhotic liver. CONCLUSION Patients with liver cirrhosis had a smaller increase in aminotransferase levels following portal triad clamping than those with a normal liver. However, hepatic functional reserve in those with a cirrhotic liver seemed to be affected more after intermittent inflow occlusion.

Abstract
BACKGROUND Expectant mothers at high risk for preterm labor admitted to the Mother and Child Health Centers (MCH) often have psychological problems and mood disturbances. The purpose of the present study was to evaluate the effects of an interview by health professionals on their mood status. METHODS Participants consisted of 52 women admitted to the MCH of Kansai Medical University (KMU) hospital and who had delivered between December 2006 and September 2007. Interview sessions by health professionals consisting of a neonatologist and a clinical psychologist, termed 'KMU baby doctor-team interview', were held once a week. During the interview the neonatologist discussed the physiology of preterm infants and treatment for the possible complications while the clinical psychologist listened to the expectant mothers talk about their anxieties or complaints and responded to their requests as much as possible. To investigate their mood status objectively, the participants were asked to complete the Japanese version of the Profile of Mood States (POMS) before and after the first session. RESULTS On admission, more than 20% of participants ranging from 19 to 42 years of age had mood disturbances in Tension-Anxiety, Depression-Dejection, and Vigor categorized by POMS. The average score for Depression-Dejection, however, significantly improved after the first interview sessions. CONCLUSIONS Mood disturbances were observed in a considerable number of expectant mothers at high risk for preterm labor. Interviews by health professionals consisting of a neonatologist and a clinical psychologist may alter their mood status.

Abstract
A 52-year-old woman underwent the surgical treatment for osteosarcoma of the left mandible in 2003 and was followed up afterward. She suffered from dry cough and bloody sputum, and was admitted to our hospital in April 2007. Computed tomography (CT) revealed several nodules in bilateral lung, and bronchofiberscopy showed the endobronchial tumor obstructing in the right main bronchus. The metastatic tumor progressed in the right main bronchus from the right S6 lung segment. The tumor rapidly progressed in the right bronchus in comparison with the CT findings in about 2 weeks, and the possibility of the tracheal obstruction was considered. She underwent the right middle and lower lobectomy, and the endobronchial tumor was pulled through the right main bronchus. The postoperative course was uneventful, the patient was discharged on 14th postoperative day, and the chemotherapy using cisplatin (CDDP) and adriamycin (ADR) is on-going.

Abstract
Adenocarcinoma of the thymus is a very rare malignant tumor. The standard treatment for advanced thymic carcinoma has not yet been established, and the prognosis is poor. We report a case of thymic carcinoma that involving the aortic arch and the innominate vein. A 78-year-old woman was admitted to our hospital complaining of hoarseness in April 2007. The computed tomography (CT) scan showed an anterior mediastinal tumor contiguous to the aortic arch and the innominate vein with swelling lymphnodes. Microspcopic examinations of specimens obtained by CT-guided needle biopsy revealed poorly differenciated adenocarcinoma. The carcinoembryonic antigen (CEA) level of serum elevated at 54.9 ng/ml. Thymic carcinoma was diagnosed. The chemoradiotherapy [concurrent, carboplatin (CBDCA) + paclitaxel(TXL)-->vinorelbine (NVB), 60 Gy] was performed, but the effect of the therapy was limited. The resection of the tumor with a part of aortic arch and other peripheral tissues was performed in Augast 2007. The postoperative course was uneventful and the CEA level of serum lowered to the normal. She was discharged 30 days after surgery.

Abstract
This clinical practice guideline provides recommendations for the assessment, diagnosis and treatment of school-aged children and juveniles with orthostatic dysregulation (OD), usually named orthostatic intolerance in USA and Europe. This guideline is intended for use by primary care clinicians working in primary care settings. The guideline contains the following recommendations for diagnosis of OD: (i) initial evaluation composed of including and excluding criteria, the assessment of no evidence of other disease including cardiac disease and so on; (ii) a new orthostatic test to determine four different subsets: instantaneous orthostatic hypotension, postural tachycardia syndrome, neurally mediated syncope and delayed orthostatic hypotension; (iii) evaluation of severity; and (iv) judgment of psychosocial background with the use of rating scales. The guideline also contains the following recommendations for treatment of OD on the basis of the result of an orthostatic test in addition to psychosocial assessment: (i) guidance and education for parents and children; (ii) non-pharmacological treatments; (iii) contact with school personnel; (iv) use of adrenoceptor stimulants and other medications; (v) strategies of psychosocial intervention; and (vi) psychotherapy. This clinical practice guideline is not intended as a sole source of guidance in the evaluation of children with OD. Rather, it is designed to assist primary care clinicians by providing a framework for decision making of diagnosis and treatments.

Abstract
An abnormal shadow was detected on chest X-ray mass screening in an asymptomatic 63-year-old man. The further examinations revealed the shadow to be primary lung cancer (Rt. S6. adenocarcinoma, cT2N0M0, c-stage IB) with right aortic arch. We used 3 dimentional-computed tomography (3D-CT) to assess an anatomical feature of vessels in detail. The right lower lobectomy and the dissection of medi astinal lymph nodes was performed. We confirmed no abnormal anatomy of pulmonary artery and vein at surgery, and it was possible to perform right lower lobectomy with the common procedure. Since lymph node was found by intraopetrative pathological examination, since no metastasis from interlobar to subcarinal lymph node was found, we did not perform dissection of upper mediastinal dissection, which was equivalent to ND2a lymph nodes dissection of the left lung cancer in General Rule for Clinical and Pathological Record of Lung Cancer. The patient with right aortic arch is known to have variant anatomy of other intrathoracic vessels occasionally. 3D-CT was quite useful in assessing anatomical feature, and enabled us to perform safe operation.

Abstract
In adult-to-adult living donor liver transplantation (LDLT), left-lobe grafts can sometimes be small-for-size. Although attempts have been made to prevent graft overperfusion through modulation of portal inflow, the optimal portal venous circulation for a liver graft is still unclear. Hepatic hemodynamics were analyzed with reference to graft function and outcome in 19 consecutive adult-to-adult LDLTs using left-lobe grafts without modulation of graft portal inflow. Overall mean graft volume (GV) was 398 g, which was equivalent to 37.8% of the recipient standard liver volume (SV). The GV/SV ratio was less than 40% in 13 of the 19 recipients. Overall mean recipient portal vein flow (PVF) was much higher than the left PVF in the donors. The mean portal contribution to the graft was markedly increased to 89%. Average daily volume of ascites revealed a significant correlation with portal vein pressure, and not with PVF. When PVP exceeds 25 mmHg after transplantation, modulation of portal inflow might be required in order to improve the early postoperative outcome. Although the study population was small and contained several patients suffering from tumors or metabolic disease, all 19 patients made good progress and the 1-year graft and patient survival rate were 100%. A GV/SV ratio of less than 40% or PVF of more than 260 mL/min/100 g graft weight does not contraindicate transplantation, nor is it necessarily associated with a poor outcome. Left-lobe graft LDLT is still an important treatment option for adult patients.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is the standard treatment for symptomatic gallbladder disease. The identification of factors that reliably predict the likely need to convert LC to an open procedure would provide short-term benefits in terms of patient education and postoperative expectations. METHODS Between 1993 and 2004, 1179 elective LCs were attempted from a total of 1339 elective cholecystectomies. The change in conversion rate between 1993-1999 and 2000-2004 was analysed. Factors predictive of higher risk for conversion were also identified. RESULTS Eighty-nine LCs (7.5 per cent) required conversion. Gallbladder wall thickness and a history of common bile duct (CBD) stones, treated by preoperative endoscopic sphincterotomy, were predictors of conversion. The proportion of patients who underwent LC was the same in 1993-1999 (87.5 per cent) and 2000-2004 (88.8 per cent), but the conversion rate increased significantly from 5.3 to 10.6 per cent in these two time intervals. In addition, the proportion of patients with a history of CBD stones rose significantly, from 6.4 per cent in 1993-1999 to 11.0 per cent in 2000-2004. CONCLUSION The conversion rate increased over the 12-year interval of the study. A history of preoperative endoscopic sphincterotomy and a thickened gallbladder wall contributed to the likelihood of conversion.

Abstract
This article describes a new technique for performing a laparoscopy-assisted right hepatic lobectomy using a hanger wall-lifting procedure. The patient is placed in the left semi-lateral position. A cholecystectomy and hemi-hepatic vascular inflow control are then performed through a midline incision, through which the resected liver can be removed. Next, the right lower chest and right upper abdominal wall are lifted by two wires vertical to the abdominal wall. Two ports, a 5-mm port in right lateral abdomen for forceps and a 12-mm port just right of the umbilicus for the laparoscope, are inserted. The obtained view of the operative field in the right upper abdominal cavity is thus excellent. The laparoscopy-assisted mobilization of the right hepatic lobe is done with the assistance of a hand inserted through the midline incision, including a dissection of the hepato-renal ligament, the right triangular ligament, and the right coronary ligament. A parenchymal dissection is then performed using the Cavitron Ultrasonic Surgical Aspirator (CUSA) and the resected specimen is passed through the midline incision without any morcellation of the liver. This procedure can minimize the length of the wound, while avoiding the lethal complications associated with pneumoperitoneum.

Abstract
BACKGROUND The aim of this study was to assess the impact of immunohistochemically identified lymph node metastasis on survival in patients with carcinoma of the ampulla of Vater. METHODS Three hundred and twenty-six regional lymph nodes dissected from pancreatoduodenectomy specimens from 25 patients with ampulla of Vater carcinoma were immunostained with anticytokeratin antibody (CAM 5.2). The clinicopathological significance of immunohistochemically detectable lymph node metastasis was evaluated and compared with that of other potential prognostic factors. RESULTS The frequency of lymph node involvement in relation to the total number of dissected lymph nodes increased from 5.5 per cent (18 of 326) using haematoxylin and eosin staining to 9.5 per cent (31 of 326) using cytokeratin immunostaining (P < 0.001). Lymph node involvement was revealed by haematoxylin and eosin staining in eight of 25 patients and by cytokeratin immunostaining in 11 of 25 patients (P = 0.006). Absence of immunohistochemically detectable lymph node metastasis was identified as an independent predictor of improved postoperative survival. CONCLUSION Immunostaining of dissected lymph nodes adds additional information to data obtained by conventional haematoxylin and eosin staining when determining the prognosis of patients with carcinoma of the ampulla of Vater.

Abstract
BACKGROUND The number of children with psychosomatic and psychosocial disorders has been increasing in Japan. There are, however, few trained pediatricians who have adequate knowledge of the treatment needed. The Research Group on the Promotion of Management of Children with Psychosomatic and Psychosocial Disorders carried out the present study to (i) disseminate knowledge about psychosomatic and psychosocial disorders of children; and (ii) establish a community-based network model to ensure effective communication among relevant institutions. METHODS To disseminate knowledge of the psychosocial and psychosomatic disorders, the Research Group compiled the Handbook for Psychosomatic Disorders of Children and distributed it to pediatricians throughout Japan. A follow-up questionnaire survey was then carried out. Also, in order to examine the current status of the communication network between pediatricians and the related institutions, the Research Group conducted a questionnaire survey on general pediatricians. RESULTS Sixty-five percent of the respondents indicated that they were actually using the Handbook. The topics in the Handbook that were most frequently referred to by the respondents were attention deficit hyperactivity disorders, school refusal, eating disorders, and orthostatic dysregulation. Thirty-seven percent of the participants indicated changes in their behavior towards psychosomatic and psychosocial problems. The results of the survey on communication networks found that the pediatricians generally collaborated with different institutions depending on the nature of the problems, such as school refusal and bullying, developmental disorders, child abuse and maltreatment, and others. CONCLUSION Promotion of the Handbook would greatly contribute to improving the management of children with psychosomatic and psychosocial disorders, together with the construction of the basic network model for management of these children.

Abstract
This study evaluated the effect of the implementation of game on mental health among participants in a bedrest (BR) experiment. Subjects were 12 healthy males aged 20-26, who participated in a 20-day 6-degrees head-down tilting BR experiment. The participants were asked to complete psychometrical questionnaires before, during, and after the experiment. We entrusted the participants to manage their leisure time and they intended a game in which all of them could take part over the experiment period. The general conversation and light-hearted mood among the subjects continued during the experimental period. Longitudinal data analysis showed that levels of neurosis and mood status did not deteriorate during the experiment, while our previous experiments, which were performed under the same protocol as this study except for the implementation of the game showed a distinct deterioration in psychosocial status. We consider that the implementation of game autonomously contributes to the positive effects on the mental health among the participants.

Abstract
We evaluated the usefulness of measurements of the inferior vena cava (IVC) diameters on abdominal echograms as an indicator of changes of venous return in subjects with orthostatic intolerance (OI) induced by simulated microgravity. We performed a standing test and recorded the IVC diameters on abdominal echograms in 12 subjects placed on a 20-day 6° head-down-tilt bed-rest experiment. We found that different patterns of changes in IVC diameter occurred in the standing test on day 10 of the experiment; in five subjects with a marginal decrease in pulse pressure, IVC diameters in the upright position were markedly decreased compared with those in the supine position. In five subjects with feelings of discomfort, the IVC diameters in the upright position distended or did not decrease from those in the supine position. These results suggested that the changes in IVC diameter on the standing test indicated the presence of various types of hemodynamic responses of OI caused by simulated microgravity. In this study, we also evaluated changes in body-water compartments by conducting multifrequency bioelectrical impedance analysis. Longitudinal data analysis showed that the total body-water-to-fat-free mass and extracellular fluid-to-fat-free mass ratios decreased during the experimental period and recovered thereafter, and that the ratio of intracellular fluid to fat-free mass decreased during the experiment. No significant difference in changes in body-water compartments was seen among subjects with different patterns of changes in IVC diameters. Measurement of IVC diameter was useful to estimate hemodynamic changes in subjects with OI.

Abstract
This study evaluated changes of mood status and depressive and neurotic levels in nine young male subjects during a 20-day 6 degrees head-down tilting bed rest and examined whether exercise training modified these changes. Participants were asked to complete psychometrical inventories on before, during, and after the bed rest experiment. Depressive and neurotic levels were enhanced during bed rest period according to the Japanese version of Zung's Self-rating Depression Scale and the Japanese version of the General Health Questionnaire. Mood state "vigor" was impaired and "confusion" was increased during bed rest and recumbent control periods compared to pre-bed rest and ambulatory control periods according to the Japanese version of Profiles of Mood State, whereas the mood "tension-anxiety", "depression-dejection", "anger-hostility" and "fatigue" were relatively stable during experiment. Isometric exercise training did not modify these results. Microgravity, along with confinement to bed and isolation from familiar environments, induced impairment of mental status.

Abstract
When Escherichia coli B was aerobically grown at 43 degrees C in a medium whose concentration was one-fourth that of the Luria-Bertani (LB) medium supplemented with 1.5 g/l of glutamic acid, drastic cell death was observed after the end of the logarithmic growth phase. However, when the same experiment was conducted under inhomogeneous 5.2-6.1 T magnetic field, cell death was extremely suppressed and the ratio of viable cell number under high magnetic field to that under geomagnetic field reached as much as 100,000. When the magnetic field exposure was restricted to 12 h after the logarithmic growth phase, a similar high degree of suppressive effect on the death was observed. The findings that the amount of sigma S protein encoded by the rpoS gene under the high magnetic field was larger than that under the geomagnetic field, and that the magnetic field effect disappeared when the rpoS gene-deficient strain was cultivated under the high magnetic field, suggest the interaction of magnetic field with a stationary phase specific gene.

Abstract
BACKGROUND Although administration of cromolyn sodium is one of the most useful drugs for the treatment of aspirin-intolerant asthma (AIA), both its pharmacologic mechanism of action and association with the pathogenesis remain obscure. OBJECTIVE This study was designed to investigate the protective effect of cromolyn sodium on airway responsiveness to the sulpyrine provocation test, and to examine whether its activity is associated with a reduction in eosinophilic inflammation. METHODS Patients were randomly assigned to receive cromolyn sodium (20 mg/2 mL, or 1 ampoule; Fujisawa, Osaka, Japan) or matching placebo (2 mL of saline) four times daily for 1 week. We evaluated the effects of pretreatment with cromolyn sodium on bronchoconstriction precipitated by inhalation of sulpyrine in 16 adult patients with mild or moderate AIA; those who were in stable clinical condition were allocated to this study. A double-blind, randomized, crossover design was used. Blood and sputum samples were taken in the morning on the sulpyrine provocation testing day. Eosinophil counting and measurement of eosinophilic cationic protein (ECP) were performed. RESULTS Inhaled cromolyn sodium protect against aspirin-induced attacks of asthma through mechanisms not related to the bronchodilator property, but related to the improvement of the bronchial hypersensitivity, almost completely in all patients (P < 0.001). After 1 week's treatment with cromolyn sodium, patients' symptoms, blood and sputum eosinophils counts, and sputum ECP levels were significantly decreased compared with both placebo and baseline. CONCLUSIONS Cromolyn sodium has a bronchial anti-inflammatory effect associated with decreased eosinophilic infiltration. This is the first report that cromolyn sodium reduces blood and sputum eosinophils counts and sputum ECP levels in AIA.

Abstract
When Escherichia coli B was aerobically grown in a medium containing one-fourth the concentration of the LB medium supplemented with glutamic acid at 43 degrees C under an inhomogeneous 5.2-6.1 T magnetic field, the number of cells in the stationary phase under the high magnetic field was 100,000 times higher than that under a geomagnetic field. The finding that the amount of sigma S factor encoded by the rpoS gene under the high magnetic field was larger than that under the control geomagnetic field indicated that the activity of the rpoS gene was affected by the high magnetic field.
