Abstract
OBJECTIVE To implement an advanced objective structured clinical examination (OSCE) in the curriculum and to evaluate Japanese pharmacy students' skills in physical assessment such as measuring pulse and blood pressure, and assessing heart, lung, and intestinal sounds. DESIGN An advanced OSCE was implemented in a hospital pharmacy seminar as a compulsory subject. We programmed patient simulators with 21 different patient cases in which normal and abnormal physiological conditions were produced. The virtual patients were then used to evaluate the physical assessment skills of fifth-year pharmacy students. ASSESSMENT Significant differences were observed between the average of all the detailed evaluations and the mean results for the following skills: pulse measurement, blood pressure measurement, deflating the cuff at a rate of 2-3 mmHg/sec, listening to heart sounds, and listening to lung sounds. CONCLUSION Administering an advanced OSCE using virtual patients was an effective way of assessing pharmacy students' skills in a realistic setting. Several areas in which pharmacy students require further training were identified.

Abstract
Purpose To investigate the relation between the quantitative iris parameters and iridotrabecular contact (ITC) in patients with primary angle-closure (PAC) and PAC glaucoma (PACG). Materials and methods PAC and PACG with laser peripheral iridotomy were recruited prospectively. Anterior-segment optical coherence tomography (ASOCT) was performed under light and dark conditions, and scans were taken along the vertical and horizontal axes. Iris thickness at 500 μm (IT500) and 750 μm (IT750) from the scleral spur, maximal iris thickness (MIT), and cross sections of the iris area (I-Area) were measured by using software. ITC was defined by the ASOCT as the contact between the peripheral iris and angle wall anterior to the scleral spur. The ITC+ and ITC− groups were defined as eyes that had ITC in two or more quadrants and in no or one quadrant, respectively. Results A total of 79 eyes of 60 patients (consisting of 48 PAC and 31 PACG) were recruited. The prevalence of superior, inferior, temporal, and nasal ITC was 44 eyes (55.7%), 48 eyes (60.8%), 18 eyes (22.8%), and 16 eyes (20.2%), respectively. These iris parameters of the inferior quadrant, which had the highest prevalence of all the quadrants, were used for the analysis. After adjusting for age, sex, pupil size, and central anterior chamber depth, mean values of IT500 and IT750 were significantly greater in the ITC+ group than the ITC− group (P<0.05). Multivariate-adjusted odds ratios of parameters for the ITC+ group compared with the ITC− group were: IT500, 1.9 (P=0.029); IT750, 2.0 (P=0.011), MIT, 1.4 (P=0.244), and I-Area, 0.97 (P=0.406), respectively, per 0.1-unit increase. Conclusion Peripheral iris thickness is associated with ITC in patients with angle closure.

Abstract
BACKGROUND Dehydroxymethylepoxyquinomicin (DHMEQ) is a newly developed compound that inhibits nuclear factor κB activation and is reported to ameliorate animal models of various inflammatory diseases without significant adverse effects. Because nuclear factor κB is a transcription factor that plays a critical role in the pathophysiology of asthma, DHMEQ may be of therapeutic benefit in asthma. OBJECTIVE The purpose of this study was to evaluate the effects of DHMEQ on airway inflammation and remodelling in murine models of asthma. METHODS The BALB/c mice were sensitized and then challenged acutely or chronically with ovalbumin and administered DHMEQ intraperitoneally before each challenge. Inflammation of airways, lung histopathology and airway hyper responsiveness to methacholine challenge were evaluated. In addition, the effect of DHMEQ on production of cytokines and eotaxin-1 by murine splenocytes, human peripheral blood mononuclear cells and bronchial epithelial cells was investigated. RESULTS Airway hyper responsiveness was ameliorated in both acutely and chronically challenged models by treatment with DHMEQ. DHMEQ significantly reduced eosinophilic airway inflammation and levels of Th2 cytokines in bronchoalveolar lavage fluid in the acute model. It also inhibited parameters of airway remodelling including mucus production, peribronchial fibrosis and the expression of α-smooth muscle actin. Moreover, the production of Th2 cytokines from murine splenocytes and human peripheral blood mononuclear cells and the production of eotaxin-1 by bronchial epithelial cells were inhibited by DHMEQ. CONCLUSIONS AND CLINICAL RELEVANCE These results indicate that DHMEQ inhibits allergic airway inflammation and airway remodelling in murine models of asthma. DHMEQ may have therapeutic potential in the treatment of asthma.

Abstract
Purpose: We compared the intraocular pressure (IOP)-lowering effect of tafluprost 0.0015% once daily with travoprost 0.004% once daily in Japanese patients with normal-tension glaucoma (NTG). Methods: One hundred sixteen patients with NTG were randomized to use tafluprost 0.0015% or travoprost 0.004% once daily for 12 weeks, followed by a washout period of 4 weeks between switching medications. IOP was measured at baseline and 4, 8, and 12 weeks of each treatment period. Results: Ninety patients completed both treatment periods and had IOP data available for evaluation. In both groups, a significant decrease in IOP was observed for all measurement points compared with baseline values (P < 0.0001). There was no significant difference in IOP at each time point between the two groups. Both drugs were effective (defined as more than 10% IOP reduction) in 39 (43%) of 90 patients; only tafluprost was effective in 26 (29%) patients, and only travoprost was effective in 17 (19%) patients. Eight (9%) patients were nonresponders to both drugs. Conclusions: Tafluprost and travoprost were equally effective in lowering IOP in patients with normal-tension glaucoma. However, patients with normal-tension glaucoma may vary in response to each medication.

Abstract
OBJECTIVES Sclerotherapy is useful for the treatment of arteriovenous vascular malformations. However, intravascular administration of sclerotic agents into small arteriovenous niduses is often difficult. Extravascular administration of sclerotic agents causes reduction of vascular flow on Doppler echo during clinical sclerotherapy. Therefore, we aimed to investigate whether the extravascular injection of sclerotic agents affects tiny vessels. DESIGN Animal study. MATERIALS The effect of extravascular injection of sclerotic agents on vessels was investigated using rat femoral and superficial inferior epigastric vessels. METHODS After surgical exposure of vessels, absolute ethanol, 5% ethanolamine oleate and 3% polidocanol were injected into perivascular surrounding tissues, and their effect on vessels was evaluated after 14 days using histology and coloured silicone rubber injection. RESULTS The integrity of the vascular lumen, endothelial cells and vascular patency were not affected by injection of sclerotic agents. CONCLUSIONS Attenuation of vascular flow of an arteriovenous shunt after extravascular injection of sclerotic agents is transient and/or trivial and does not cause disruption of vessels. Therefore, sclerotic agents should be delivered to obtain sufficient destruction of arteriovenous malformation lesions and blood flow.

Abstract
BACKGROUND The anesthetic conserving device (AnaConDaTM) is a disposable vaporizer that can save consumption of inhalational anesthetic used in low sevoflurane concentration. This study was performed to investigate whether AnaConDa when used at high sevoflurane concentration (1.5% to 2.0%) could save sevoflurane consumption and hasten emergence from anesthesia without any adverse effects. METHODS Thirty patients for ear surgery were equally divided into AnaConDa and control groups. Anesthesia was induced with intravenous anesthetics. After intubation sevoflurane inhalation started by infusion at 25 mL/h in the AnaConDa group and by inhalation of 2.0% (conventional vaporizer setting) in the control group. During anesthesia, end-tidal sevoflurane concentration was kept between 1.5 and 2.0% in both groups. The time to first detection of end-tidal sevoflurane, the time to sevoflurane concentration reached 1.5%, sevoflurane consumption, and emergence time were compared between the two groups. Adverse effects were checked. RESULTS Sevoflurane consumption was smaller, time to first detection of end-tidal sevoflurane was longer, time to sevoflurane concentration reached 1.5% was longer, emergence time was shorter, and decrease of end-tidal sevoflurane concentration after stop of administration was faster in the AnaConDa group significantly. Clear Water accumulation with no smell in the filter was observed in 12 of 15 patients in the AnaConDa group. CONCLUSION In general anesthesia with sevoflurane 1.5% to 2.0%, AnaConDa could save sevoflurane consumption and fasten emergence from anesthesia compared to conventional vaporizer, while water accumulation in the filter should be cautioned.

Abstract
We measured separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope. Because the instrument does not have an onboard magnet, we distinguish the two species by exploiting Earth's shadow, which is offset in opposite directions for opposite charges due to Earth's magnetic field. We estimate and subtract the cosmic-ray proton background using two different methods that produce consistent results. We report the electron-only spectrum, the positron-only spectrum, and the positron fraction between 20 and 200 GeV. We confirm that the fraction rises with energy in the 20-100 GeV range. The three new spectral points between 100 and 200 GeV are consistent with a fraction that is continuing to rise with energy.

Abstract
Satellite galaxies of the Milky Way are among the most promising targets for dark matter searches in gamma rays. We present a search for dark matter consisting of weakly interacting massive particles, applying a joint likelihood analysis to 10 satellite galaxies with 24 months of data of the Fermi Large Area Telescope. No dark matter signal is detected. Including the uncertainty in the dark matter distribution, robust upper limits are placed on dark matter annihilation cross sections. The 95% confidence level upper limits range from about 10(-26) cm3 s(-1) at 5 GeV to about 5×10(-23) cm3 s(-1) at 1 TeV, depending on the dark matter annihilation final state. For the first time, using gamma rays, we are able to rule out models with the most generic cross section (∼3×10(-26) cm3 s(-1) for a purely s-wave cross section), without assuming additional boost factors.

Abstract
Purpose To evaluate the intraocular pressure (IOP)-lowering effect of adding dorzolamide 1.0%/timolol 0.5% fixed combination (DTFC) to prostaglandin analogs (PGAs) as monotherapy in patients with normal tension glaucoma. Methods A prospective, clinical, case-controlled study of patients with normal tension glaucoma. Patients had been on a once-daily night dose of prostaglandins (PGs) as monotherapy and then received DTFC added to PGs for 8 weeks. The IOP was measured at 9 am, week 0 (baseline), week 4, and week 8. Results The baseline IOP of 40 patients who had previously been treated by prostaglandin monotherapy was 15.6 ± 2.0 mmHg at baseline. The IOPs at 4 and 8 weeks after adding DTFC to PGs were 13.5 ± 2.1 mmHg and 13.7 ± 2.2 mmHg, respectively. Significant decrease of the IOP was observed at each time point of measurement as compared with the baseline IOP before adding DTFC (P = 0.01). The percent IOP reduction from the baseline IOP at week 4 and week 8 was 13.5% ± 12.3% and 11.7% ± 13.1%, respectively. The percentage of patients who achieved 10% or more IOP reduction from the baseline IOP at week 8 was 62.5%. The baseline IOP was significantly correlated with the percent IOP reduction at week 8 (P = 0.03, r = 0.34). Conclusion DTFC therapy added to PGAs as glaucoma monotherapy is effective in patients with normal tension glaucoma.

Abstract
We report a case of successful treatment of a ruptured distal aortic arch aneurysm with cardiac tamponade by using selective cerebral perfusion for protecting the brain. A 79-year-old man had sudden onset of severe chest and back pain. Chest computed tomography (CT) suggested an acute aortic dissection. He was immediately transferred to the emergency room of our hospital. Echocardiography performed on admission revealed intrapericardial fluid, and hemodynamic monitoring suggested cardiac tamponade. After pericardiocentesis and removal of 400 ml bloody fluid, his hemodynamic condition became stable. Enhanced chest CT showed ruptured distal aortic arch aneurysm with pericardial and pleural effusion. Emergency patch plasty of the aneurysm under extracorporeal circulation (ECC) was performed, assisted by selective cerebral perfusion and deep hypothermia. The patient's postoperative course was uneventful, except for minor transient respiratory troubles, and he was able return to his usual activity.

Abstract
Novae are thermonuclear explosions on a white dwarf surface fueled by mass accreted from a companion star. Current physical models posit that shocked expanding gas from the nova shell can produce x-ray emission, but emission at higher energies has not been widely expected. Here, we report the Fermi Large Area Telescope detection of variable gamma-ray emission (0.1 to 10 billion electron volts) from the recently detected optical nova of the symbiotic star V407 Cygni. We propose that the material of the nova shell interacts with the dense ambient medium of the red giant primary and that particles can be accelerated effectively to produce pi(0) decay gamma-rays from proton-proton interactions. Emission involving inverse Compton scattering of the red giant radiation is also considered and is not ruled out.

Abstract
PURPOSE Polymorphisms in the promoter regions of matrix metalloproteinase (MMP) genes can cause variations in the expression of the MMP genes in the sclera that can lead to a greater susceptibility to axial elongation of the eye. The purpose of this study was to determine whether functional single-nucleotide polymorphisms (SNPs) in the MMP1, -2, and -3 promoter regions are associated with high myopia in the Japanese. METHODS Seven hundred twenty-five unrelated Japanese patients with high myopia (axial length of >or=26.0 mm in both eyes, or refractive error>or=-6.0 D in phakic cases) and >or=40 years of age were studied. Five hundred forty-six healthy, unrelated Japanese who were >or=40 years of age served as population-based control subjects. All the subjects were genotyped for the four functional SNPs MMP1 -1607 1G/2G, MMP2 C-1306T, MMP2 C-735T, and MMP3 -1612 5A/6A with an SNP assay. The distribution of the genotypes in the cases and control subjects was compared by the chi2 test for trend. RESULTS No significant difference was detected in the distribution of the four SNPs MMP1 -1607 1G/2G (P=0.92), MMP2 C-1306T (P=0.83), MMP2 C-735T (P=0.10), and MMP3 -1612 5A/6A (P=0.62), between the high myopia cases and the general-population controls. CONCLUSIONS The four functional SNPs in the MMP1, -2, and -3 promoter regions do not play critical roles in the development of high myopia in the Japanese population.

Abstract
Dark matter (DM) particle annihilation or decay can produce monochromatic gamma rays readily distinguishable from astrophysical sources. gamma-ray line limits from 30 to 200 GeV obtained from 11 months of Fermi Large Area Space Telescope data from 20-300 GeV are presented using a selection based on requirements for a gamma-ray line analysis, and integrated over most of the sky. We obtain gamma-ray line flux upper limits in the range 0.6-4.5x10{-9} cm{-2} s{-1}, and give corresponding DM annihilation cross-section and decay lifetime limits. Theoretical implications are briefly discussed.

Abstract
BACKGROUND/AIMS Liver regeneration after surgical resection is important. The present study was designed to understand the effect of background liver damage on the rate of liver tissue regeneration after hepatectomy and the mechanism of any defective regeneration. METHODOLOGY The subjects were 40 patients who underwent liver resection. They comprised 22 patients with chronic viral hepatitis-hepatocellular carcinoma (liver damage group) and 18 patients with hepatic metastases from colorectal cancer (normal liver group). Liver regeneration was evaluated by histopathological and immunohistochemical examination of the surgically resected tissue and by CT-scanning of the regenerated liver mass. The resected liver specimens were stained for c-met, gp-130 and nuclear factor-kappaB (NF-kappaB) proteins. RESULTS Liver regeneration was significantly less in the liver-damage group than in the normal-liver group. Histopathological examination showed marked inflammatory cell infiltration in the liver-damage group. Expression of c-met, but not gp-130, was significantly higher on parenchymal cells of the liver-damage group than the normal-liver group. NF-kappaB expression in parenchymal liver cells was significantly higher than in non-parenchymal cells of the normal-liver group. In the liver-damage group, liver regeneration correlated negatively with the staining intensity of NF-kappaB protein in non-parenchymal cells. These findings suggest that non-parenchymal cells are constitutively activated in the damaged liver, probably explaining the refractoriness of hepatocytes to cytokine-induced proliferation after hepatectomy, in spite of increased receptor (c-met) expression. CONCLUSIONS The refractory response of injured hepatocytes to cytokines may explain the impaired postoperative liver regeneration in patients with damaged liver.

Abstract
Designed as a high-sensitivity gamma-ray observatory, the Fermi Large Area Telescope is also an electron detector with a large acceptance exceeding 2 m;{2} sr at 300 GeV. Building on the gamma-ray analysis, we have developed an efficient electron detection strategy which provides sufficient background rejection for measurement of the steeply falling electron spectrum up to 1 TeV. Our high precision data show that the electron spectrum falls with energy as E-3.0 and does not exhibit prominent spectral features. Interpretations in terms of a conventional diffusive model as well as a potential local extra component are briefly discussed.

Abstract
AIMS/HYPOTHESIS We analysed the association between humoral autoreactivity to zinc transporter-8 (ZnT8) and the SLC30A8 rs13266634 polymorphism (Arg325Trp), which is located at the most distal loop in the ZnT8 protein. METHODS Autoantibodies to ZnT8 were determined by RIA in 270 patients with type 1 diabetes using ZnT8 carboxy-terminal constructs (amino acids 268-369) carrying 325Trp(CW) and 325Arg(CR) and a hybrid construct (CW-CR). Forty-four ZnT8 autoantibody-positive sera with genomic DNA were used to examine the association between reactivity to ZnT8 constructs and the rs13266634 genotype. RESULTS Seventy-five patients reacted to the CW-CR hybrid construct, whereas 37 and 36 patients reacted to the CW and CR constructs, respectively. All sera positive for either CW or CR autoantibodies were positive for CW-CR autoantibodies. Among 19 patients with a 325Arg(CC) genotype, 5% had CW-specific autoantibodies, 42% had CR-specific autoantibodies and 32% had dual reactivity. Conversely, 73% of 15 patients with the 325Trp(TT) genotype had CW-specific autoantibodies, no patients had CR-specific autoantibodies and 13% had dual reactivity. Nine of the ten patients (90%) with the CT genotype reacted with either CR or CW constructs. The titre of CR autoantibodies in patients carrying the C allele was significantly higher than that in TT homozygotes (p < 0.0001). In contrast, the titre of CW autoantibodies in patients carrying a T allele was significantly higher than that in CC homozygotes (p < 0.005). No evidence of an association between rs13266634 and type 1 diabetes was observed. CONCLUSIONS/INTERPRETATION These results indicate that variant residue at amino acid 325 is a key determinant of humoral autoreactivity to ZnT8 and that the SLC30A8 genotype is an important determinant of autoantibody specificity.

Abstract
To test the possibility of a peroxisome proliferator activated receptor (PPAR) γ agonist to treat neuropathic pain, we examined the effects of pioglitazone, a PPARγ agonist, on tactile allodynia and expression of activated microglia in the dorsal horn of spinal cord using neuropathic pain model. The unilateral sciatic nerve was partially ligated (PSL) in male ICR mice. Pioglitazone (1-25 mg/kg p.o.) was administrated to mice once daily for five days immediately after PSL. We stimulated the footpad of the hind paw of mice using a von Frey filament to estimate tactile allodynia on day 5 of PSL. The activated microglia in the lumbar spinal cord was observed by immunohistochemistry with anti-Iba1 antibody, a marker for activated microglia. The number of Iba1-immunoreactive cells was counted in the dorsal horn spinal cord. On day 5, significant allodynia was developed in PSL mice. Pioglitazone significantly attenuated the tactile allodynia in a dose of 1-25 mg/kg. However, these doses of pioglitazone did not affect nociceptive responses in sham mice. Moreover, on day 6, the number of activated microglia was significantly increased in the ipsilateral dorsal horn of mice. The increase in the number of activated microglia induced by PSL was significantly suppressed by pioglitazone (1-25 mg/kg p.o.). Pioglitazone did not affect the number of activated microglia in sham mice. These results suggest that PPARγ activation inhibits the development of tactile allodynia and the expression of activated microglia in the dorsal horn of spinal cord in mice with PSLinduced peripheral nerve injury.

Abstract
Energetic young pulsars and expanding blast waves [supernova remnants (SNRs)] are the most visible remains after massive stars, ending their lives, explode in core-collapse supernovae. The Fermi Gamma-Ray Space Telescope has unveiled a radio quiet pulsar located near the center of the compact synchrotron nebula inside the supernova remnant CTA 1. The pulsar, discovered through its gamma-ray pulsations, has a period of 316.86 milliseconds and a period derivative of 3.614 x 10(-13) seconds per second. Its characteristic age of 10(4) years is comparable to that estimated for the SNR. We speculate that most unidentified Galactic gamma-ray sources associated with star-forming regions and SNRs are such young pulsars.

Abstract
PURPOSE The single nucleotide polymorphisms (SNPs) rs1048661, rs3825942, and rs2165241 within the LOXL1 gene were recently found to confer risk of pseudoexfoliation glaucoma (XFG) through pseudoexfoliation syndrome (XFS) in Caucasians. The purpose of this study was to test this association in Japanese subjects with XFS/XFG. METHODS Japanese subjects with clinically diagnosed XFS/XFG and normal control subjects were recruited. Genomic DNA was extracted and the three SNPs of the LOXL1 gene were genotyped by bidirectional sequencing. The association of individual SNPs with XFG/XFS was evaluated by using chi(2) and the Fisher exact test. RESULTS Two hundred nine Japanese patients (106 XFG and 103 XFS) and 172 control subjects were studied. Strong associations were observed for all three SNPs of LOXL1 for XFS (odds ratio [OR] = 13.56, P = 3.39 x 10(-28) for allele T of rs1048661; OR = 10.71, P = 1.49 x 10(-7) for allele G of rs3825942; and OR = 4.55, P = 5.33 x 10(-4) for allele C of rs2165241) and XFG (OR = 25.21, P = 1.44 x 10(-34) for allele T of rs1048661; OR = 11.02, P = 1.40 x 10(-7) for allele G of rs3825942; and OR = 11.89, P = 4.76 x 10(-6) for allele C of rs2165241). The risk-associated alleles of rs1048661 and rs2165241 differed between the Japanese and Caucasians, whereas allele G of rs3825942 was associated with disease in both populations. Conditional analysis indicated that rs3825942 was not independent but correlated highly with rs1048661. The at-risk haplotype T-G-C was present at an approximately two times higher rate (94.7% vs. 50.6%, P = 4.22 x 10(-43)) in cases than in control subjects and conferred a 2.9-fold (95% confidence interval [CI], 2.357-3.464) increased likelihood of XFS. CONCLUSIONS Polymorphisms in the LOXL1 gene confer risk to XFS/XFG in the Japanese, but there are different risk-associated alleles and haplotypes in the Japanese.

Abstract
BACKGROUND Upregulation of oligopeptide transport activity by dietary protein, certain dipeptides and amino acids has been reported in the rat intestine and a human intestinal cell line. OBJECTIVE In this study, the pharmacokinetics of cefdinir were investigated after L-phenylalanine supplementation and a high-protein diet (HPD) in humans to explore changes in the activities of intestinal and renal oligopeptide transporters. METHODS A normal-protein diet (NPD, 73.2 +/- 2.6 g/day), NPD + l-phenylalanine (7.5 g/day), or HPD (141.3 +/- 3.7 g/day) was given to six male healthy volunteers for 12 days followed by a single dose of cefdinir after an overnight fast in a randomized three-way crossover study with a 22-day washout. Blood and urine were collected over a 12-h period after administration of cefdinir. Concentrations of cefdinir in plasma and/or urine were measured by high-performance liquid chromatography. RESULTS Plasma concentrations and urinary excretion of the drug did not change throughout the study. Physiological variables and laboratory values did not reveal any differences between the three periods except for serum and urinary nitrogen levels and serum triglyceride. DISCUSSION A reason for the unchanged pharmacokinetics of cefdinir may be due to lower doses of L-phenylalanine and protein in humans than in animals when converting animal effective doses to humans. CONCLUSION In humans, L-phenylalanine supplementation and HPD do not seem to upregulate intestinal and renal oligopeptide transport in the ranges of duration and dose examined.

Abstract
Propofol formulated in lipid supports microbial growth. We hypothesised that propofol with disodium edetate would suppress microbial growth more than propofol without disodium edetate. We examined bacterial growth in vitro and bacterial survival in the dead space of different venous access systems. Bacteria in propofol with disodium edetate (Diprivan; AstraZeneca, London, UK) and without disodium edetate (1% Propofol inj. 'Maruishi'; Maruishi Pharmaceutical Co. Ltd, Osaka, Japan) survived and grew in the dead space of the venous access systems, although propofol with disodium edetate suppressed bacterial growth more than propofol without. Disodium edetate is effective in retarding microbial growth. However, for prevention of healthcare-associated infections, medical professionals should maintain strict aseptic precautions when handling propofol, use disodium edetate-containing formulations, and should consider using venous access systems without dead space.

Abstract
We report a 67-year-old female patient with ventricular septal perforation after weak blunt chest trauma. She tumbled down on a frozen street. Approximately 1 week later, the patient was aware of shortness of breath on exertion. On admission, holosystolic murmur was detected on chest wall and routine electrocardiogram examination showed ST-T change which suggested myocardial ischemia. Acute myocardial infarction and ventricular septal defect with left-to-right shunt was suspected. The echocardiography and cardiac catheterization revealed the muscular type ventricular septal perforation near the apex with large left-to-right shunt flow (82% shunt ratio). The congestive heart failure was controlled successfully by conservative medical treatment. Surgical repair was scheduled on the 28th day after initial chest trauma because of large left-to-right shunt. A hole of about a diameter of 2 cm with fibrous edge of the muscular septum was closed through a left ventriculotomy using a Dacron patch under cardiopulmonary bypass. Postoperative course was uneventful and the patient was discharged without symptoms of congestive heart failure.

Abstract
We describe our experience with a woman who had severe non-herpetic acute limbic encephalitis at 20 weeks' gestation. Despite receiving mechanical ventilation for about 3 months because of impaired consciousness and frequent convulsions, she had a normal delivery and an uneventful recovery with no sequelae. The patient did not respond to treatment with antiviral agents. Anticonvulsant agents were given while monitoring plasma drug concentrations. Early treatment and the prevention of complications apparently contributed to good outcomes in the mother and child.

Abstract
The occurrence and fate of surface water and wastewater pathogens (faecal coliforms, Escherichia coli, Giardia lamblia and Cryptosporidium parvum) in two constructed waterways and a pond-based AIT wastewater treatment plant (AIT WWTP) in Pathumthani, Thailand were studied in the context of several biogeochemical factors and in relation to pollutional pressure and seasonal phenomena with a view to proposing potential mechanisms for their removal. More data on pathogen removal in a given local context would provide assurance that some pathogens could serve as suitable indicator organisms and predict removal of different pathogenic microorganisms such as protozoan parasites covered in this study. The enumeration technique for protozoan pathogens was improved in terms of application of emerging novel molecular technologies for the development of a fast but affordable microbiological method. Potential risk of waterborne disease outbreak in pertinent communities was then characterized using established infection probability models and the compiled pathogen occurrence data. Overall, we have addressed several strategic priorities of pathogen research in waste stabilization ponds in developing tropical countries like
