The written language performance of children with Attention Deficit Hyperactivity Disorder in Taiwan.
Poor writing is common in children with Attention Deficit Hyperactivity Disorder (ADHD). However, the writing performance of children with ADHD has been rarely formally explored in Taiwan, so the purpose of this study was to investigate writing features of children with ADHD in Taiwan. There were 25 children with ADHD and 25 normal children involved in a standardization writing assessment - Written Language Test for Children, to assess their performance at the dictation, sentence combination, adding/deducting redical, cloze and sentence making subtests. The results showed that except for the score of the sentence combining subtest, the score of children with ADHD was lower than the normal student in the rest of the subtests. Almost 60% of ADHD children's scores were below the 25th percentile numbers, but only 20% for normal children. Thus, writing problems were common for children with ADHD in Taiwan, too. First, children with ADHD performed worse than normal children on the dictation and cloze subtests, showing the weaker abilities of retrieving correct characters from their mental lexicon. Second, children with ADHD performed worse on the adding/deducting redical subtest than normal children did. Finally, at the language level, the score of children with ADHD on the sentence combination subtest was not lower than normal children, implicating their normal grammatic competence. It is worth mentioning that Taiwanese children with ADHD ignore the details of characters when they are writing, a finding that is common across languages.

title: Exploring the association between visual perception abilities and reading of musical notation.
abstract: In the reading of music, the acquisition of pitch information depends primarily upon the spatial position of notes as well as upon an individual's spatial processing ability. This study investigated the relationship between the ability to read single notes and visual-spatial ability. Participants with high and low single-note reading abilities were differentiated based upon differences in musical notation-reading abilities and their spatial processing; object recognition abilities were then assessed. It was found that the group with lower note-reading abilities made more errors than did the group with a higher note-reading abilities in the mental rotation task. In contrast, there was no apparent significant difference between the two groups in the object recognition task. These results suggest that note-reading may be related to visual spatial processing abilities, and not to an individual's ability with object recognition.

title: Assessment of participant satisfaction with upper gastrointestinal endoscopy in South Korea.
abstract: To measure the perceived satisfaction with gastric cancer screening as part of the National Cancer Screening Program (NCSP) in South Korea.



Data were derived from the participants in a satisfaction survey of the Quality Evaluation of National Cancer Screening in 2009. This is a population-based nationwide telephone survey of participants who were screened by the NCSP between May and October 2009. This study included 4412 participants who provided full sets of data and who had upper endoscopies for the purpose of gastric cancer screening.



The negative appraisal percentages for each of the seven questions were as follows: explanation in preparation for the upper endoscopy, 12.3%; explanation about the process and procedure of the upper endoscopy, 13.8%; explanation about any pain or discomfort related to the upper endoscopy, 27.5%; level of pain during the procedure, 30.3%; physical environment, 16.2%; manner of the staff, 11.2%, and privacy protection, 8.8%.



The critical issues identified by the Pareto analysis include the adequacy of the explanation about any pain or discomfort associated with the upper endoscopy and the level of pain experienced during the procedure.

title: Clinical features of echovirus 6 and 9 infections in children.
abstract: Clinical features of echovirus 6 and 9 infections in children have not been comprehensively evaluated, particularly for sporadic cases.



To describe the clinical features of children with echovirus 6 or 9 infections.



From 2000 to 2008, 199 children with culture-proven echovirus 6 or 9 infections identified in a university-affiliated hospital were included. Data extracted from 174 inpatients were further analyzed.



Age ranged from 4 days to 15 years with a mean of 4.7 years. 123 (62%) were male. The disease spectrums were similar for echovirus 6 (n=100) and 9 (n=74) infections, with aseptic meningitis (49% and 51%, respectively) being the most common syndrome, followed by meningismus, upper respiratory tract infection, pneumonia, and herpangina. All 174 inpatients had fever but the duration of fever was significantly longer in patient with echovirus 9 infection than those with echovirus 6 infections (6.0 days vs. 3.8 days, p<0.001). The rate of leukocytosis (leukocyte count>15,000/μL) were significantly higher in patients with echovirus 6 infections than those with echovirus 9 infection (p<0.001). One neonate with echovirus 6 infection died from hepatic necrosis with coagulopathy, and one infant with echovirus 6 infection and one child with echovirus 9 infection died from brain involvement. Two children had long-term sequelae of seizure disorder. The remaining 169 children (97%) recovered uneventfully.



For children with echovirus 6 or 9 infections requiring hospitalization, aseptic meningitis was the most common manifestation and fatal outcome or long-term sequel, though rare, might occur.

title: Haplotypes and mutation analysis of 22 Y-chromosomal STRs in Korean father–son pairs
abstract: We analyzed 369 Korean father/son haplotype transfers in 355 families at 22 Y-STRs (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS388, DYS437, DYS438, DYS439, DYS446, DYS447, DYS448, DYS449, DYS456, DYS458, DYS464, DYS635, and GATA H4.1). A total of 350 haplotypes were observed with an overall haplotype diversity of 0.9999. Among these, 345 were unique and five were found twice. Furthermore, 36 mutations were identified, giving locus-specific mutation rate estimates between 0.0 and 19.0 × 10−3 per generation and an average mutation rate estimate of 3.9 × 10−3 (95% CI 2.7–5.4 × 10−3). The compilation of Y-STR mutation events for the present study and previous studies demonstrates that DYS449, DYS458, DYS635, DYS456 and DYS439 are the most prone to mutations and that their overall average mutation rate estimate is 2.36 × 10–3 (95% CI 2.03–2.73 × 10–33).

title: Modeling T Cell Proliferation and Death in Vitro Based on Labeling Data: Generalizations of the Smith–Martin Cell Cycle Model
abstract: The fluorescent dye carboxyfluorescein diacetate succinimidyl ester (CFSE) classifies proliferating cell populations into groups according to the number of divisions each cell has undergone (i.e., its division class). The pulse labeling of cells with radioactive thymidine provides a means to determine the distribution of times of entry into the first cell division. We derive in analytic form the number of cells in each division class as a function of time based on the distribution of times to the first division. Choosing the distribution of time to the first division to fit thymidine labeling data for T cells stimulated in vitro under different concentrations of IL-2, we fit CFSE data to determine the dependence of T cell kinetic parameters on the concentration of IL-2. As the concentration of IL-2 increases, the average cell cycle time is shortened, the death rate of cells is decreased, and a higher fraction of cells is recruited into division. We also find that if the average cell cycle time increases with division class then the qualify of our fit to the data improves.

title: Effects of interscalene brachial plexus block to intra-operative hemodynamics and postoperative pain for arthroscopic shoulder surgery
abstract: Although arthroscopic shoulder surgery is less invasive and painful than open shoulder surgery, it can often cause intra-operative hemodynamic instability and severe post-operative pain. This study was conducted to investigate the efficacy of the interscalene brachial plexus block (IBPB) on intra-operative hemodynamic changes and post-operative pain during arthroscopic shoulder surgery.  After institutional review board approval, 50 consecutive patients that had undergone arthroscopic shoulder surgery under general anesthesia were randomly assigned to one of two groups to evaluate intra-operative hemodynamic changes and post-operative pain control. Group 1 patients received an IBPB with 10 ml of normal saline guided by a nerve stimulator before induction, and Group 2 patients received 10 ml of 0.5% ropivacaine hydrochloride with the same technique. The heart rate and systolic and diastolic blood pressures were recorded before the incision and 1, 3, 5, 10, and 20 minutes after the incision. Pre-operative and post-operative pain was evaluated with a visual analog scale 1, 3, 6, 12, and 24 hours after surgery. The patients were given tramadol as a rescue medication option. The total volume of tramadol that was injected was also evaluated over the same intervals.  Group 2 showed significantly lower systolic and diastolic blood pressures and heart rates intra-operatively compared to Group 1 (P < 0.05). The visual analog scale pain scores, except at 24 hours after surgery, were significantly lower in Group 2 (P < 0.05). The total tramadol consumption significantly reduced in Group 2 (P < 0.05).  IBPB effectively controlled the hemodynamic changes that occurred during arthroscopic shoulder surgery as well as post-operative pain.
