Abstract
Medical thoracoscopy is a valuable tool in the investigation and management of pleural disease. It has considerable advantages over conventional blind pleural biopsy and video-assisted thoracoscopic surgery. Despite this, the practice of this technique in the UK is limited. Most operators use the rigid thoracoscope, which may be an unfamiliar instrument to respiratory physicians. A semirigid thoracoscope is available but its use has not been possible in the UK as it requires sterilisation with ethylene oxide, which is not approved in this country. The present authors describe herein their experience with the first ever autoclavable semirigid thoracoscope. Medical thoracoscopy using the new instrument was performed in 56 patients between June 2004 and May 2006. All patients had been referred with a unilateral pleural effusion of unknown aetiology, where blind pleural aspiration had failed to yield an answer. Diagnostic samples were taken and talc poudrage performed where appropriate. The instrument was easy to handle and excellent views were obtained. Histologically adequate biopsy samples were obtained in 54 patients. The combination of clinical features, computed tomography findings and thoracoscopic biopsy enabled a definite diagnosis in 49 (90.7%) of these patients. There were no complications. The autoclavable semirigid thoracoscope has immense potential in the diagnosis and management of pleural disease. Its diagnostic yield in pleural disease is comparable to the conventional rigid thoracoscope. It is similar in design to the fibreoptic bronchoscope and respiratory physicians should be able to adapt to its use easily. It is also compatible with existing video processors and light sources available in most endoscopy suites. The fact that this instrument is autoclavable should open the field for its use in the UK as well as in other countries.

Abstract
OBJECTIVE The purpose of this study was to determine the incidence of pseudomeningocele and cerebrospinal fluid (CSF) leak after posterior fossa tumor surgery and to analyze factors that may be associated with these conditions. In particular, we wished to determine if there was evidence to support the hypothesis that the use of tissue glue, dural grafts, or external ventricular drainage (EVD) prevented CSF from leaking outside the closed dura. MATERIALS AND METHODS A retrospective chart review was carried out of posterior fossa tumor resections at British Columbia's Children's Hospital. Information was collected regarding tumor location, surgical approach, CSF diversion, dural grafting, and use of tissue glue. Multiple univariate analyses and step-wise logistic regression were performed to identify factors associated with pseudomeningocele formation or CSF leak. A pseudomeningocele was said to be present if it was noted in the clinical records or if a fluid collection was present superficial to the craniotomy flap on a postoperative CT or MR scan. RESULTS Out of 174 posterior fossa operations, 53 pseudomeningoceles with or without CSF leak were identified along with five CSF leaks in the absence of pseudomeningocele (33%). None of the factors examined reached statistical significance, although there was a trend towards higher rates in patients with external CSF drainage (P=0.06631), dural graft usage (p=0.06492), and patients in whom tissue glue was used (p=0.06181). On logistic regression, only tissue glue use and external CSF drainage were associated with increased incidence of pseudomeningocele and/or CSF leak. CONCLUSION In this retrospective study, the use of tissue glue, dural grafts, and external ventricular drainage was not associated with a reduced rate of clinically or radiologically diagnosed pseudomeningocele formation or postoperative CSF leak. The results of this study provide a basis for planning a randomized controlled trial to determine the effectiveness of tissue glue and/or dural grafting in preventing these complications.

Abstract
Four broad phases can be traced in the development of modern psychiatry in India. After briefly considering the outline of each of these phases this article will focus its attention on the second and third. It will be argued through tracing the trends in patient admission, treatment regimes and the organisation of the asylum system in these years that the foundations of modern psychiatry were laid in India in the period 1858 to 1947 and that the modern psychiatric system in India as it is today, although it has evolved since Independence in 1947, continues in significant ways to be shaped by the colonial period.

Abstract
A study of experiments in major social psychology journals shows that measures of independent variables have become increasingly common. The role in experiments of measures of independent variables and proposed mediating variables is examined. In the causal sequence assumed in interpreting an experimental result, the independent variable and proposed mediating variable are presumed to mediate the effect of the experimental treatment on the dependent measure. Measures of independent variables and mediators provide checks on the assumptions that the experimental treatment successfully manipulated those variables and are unquestionably useful. A separate, controversial issue is whether such measures are necessary in experiments. If no plausible alternative explanations exist, data from such measures are not needed. Plausible alternative explanations are not eliminated by data from such measures. Alternative explanations, critical for assessing construct validity (Cook & Campbell, 1979), are distinguished from different general theoretical accounts of a finding.

Abstract
Matrix proteins of viruses within the order Mononegavirales have similar functions and play important roles in virus assembly. Protein sequence alignment, phylogenetic tree derivation, hydropathy profiles and secondary structure prediction were performed on selected matrix protein sequences, using human respiratory syncytial virus matrix protein as the reference. No general conservation of primary, secondary or tertiary structure was found, except for a broad similarity in the hydropathy pattern correlating with the fact that all the proteins studied are membrane-associated. Interestingly, the matrix proteins of Ebola virus and human respiratory syncytial virus shared secondary structure homology.

Abstract
Respiratory syncytial virus (RSV) G glycoprotein mediates cell attachment through surface glycosaminoglycans (GAGs). Feldman et al. [10] suggested that specific basic amino acids in residues 184-198 of G defined a critical heparin binding domain (HBD). To further define the G HBD we made a series of truncated G proteins expressed in Escherichia coli. G88 (G residues 143-231), bound to HEp-2 cells in a dose dependent manner and binding was inhibited >99% with heparin. Cell binding of G88 was unaltered by alanine substitution mutagenesis of all basic amino acids in Feldman's region 184-198. A G88 variant truncated beyond residue 198, G58, and G58 fully alanine substituted in the region 184-198, G58A6, bound to HEp-2 cells about half as well and 100-fold less well than G88, respectively. G88 and all alanine substitution mutants of G88 inhibited RSV plaque formation by 50% (ID(50)) at concentrations of approximately 50 nM; the ID(50) of G58 was approximately 425 nM while G58A6 had an ID(50) >1600 nM. These data show that the G HBD includes as much as residues 187-231, that there is redundancy beyond the previously described HBD, and that the cell-binding and virus infectivity-blocking functions of these recombinant G proteins were closely linked and required at least one HBD.

Abstract
The matrix protein of paramyxoviruses plays an important role in virus assembly through its interactions with cell membrane, virus envelope and virus nucleocapsid. In the present study, we investigated the possible association of respiratory syncytial virus (RSV) matrix (M) protein with the plasma membrane of infected cells. Using confocal microscopy we found that M was present at the cytoplasmic side of the plasma membrane. We used flotation gradients to purify membranes from RSV infected cells and treated them with cold Triton X-100 to obtain lipid rafts in the insoluble fraction. Western blot of the lipid raft fraction with specific antibodies showed that it contained M, as well as G (attachment) and N (nucleocapsid) proteins. We also found that RSV purified on sucrose gradients contained lipid raft markers. Together, our data suggest that RSV uses lipid rafts for assembly and budding.

Abstract
We studied the kinetics of localisation of matrix (M) protein of Human respiratory syncytial virus (RSV) in infected cells. M protein was detected in the nucleus early in infection, by confocal microscopy and by immunoblotting of nuclear fractions. We next tested the possibility that M protein may be involved in inhibition of host cell transcription. Nuclear extracts from RSV infected cells had less transcriptional activity in vitro when compared to nuclear extracts from mock infected cells. In addition, nuclear extracts from RSV infected cells inhibited the transcriptional activity of nuclear extracts from mock infected cells, suggesting that an inhibitory activity was transferred with nuclear extracts from RSV infected cells. Our data suggest that M protein may play a role early in the infection by inhibiting host cell transcription.

Abstract
Mathematical models can be used as health policy tools and predictive tools. Here we review how mathematical models have been used both to predict the consequences of specific epidemic control strategies and to design epidemic control strategies. We review how models have been used to evaluate the potential impact on HIV epidemics of (i) combination antiretroviral therapies (ART) and (ii) imperfect vaccines. In particular, we discuss how models have been used to predict the potential effect of ART on incidence rates, and to predict the evolution of an epidemic of drug-resistant HIV. We also discuss, in detail, how mathematical models have been used to evaluate the potential impact of prophylactic, live-attenuated and therapeutic HIV vaccines. We show how HIV vaccine models can be used to evaluate the epidemic-level impact of vaccine efficacy, waning in vaccine-induced immunity, vaccination coverage level, and changes (increases or decreases) in risky behavior. We also discuss how mathematical models can be used to determine the levels of cross-immunity that vaccines will need to attain if they are to be used to control HIV epidemics in countries where more than one subtype is being transmitted.

Abstract
Benefit and satisfaction following endoscopic sinus surgery were assessed using the Glasgow Benefit Inventory (GBI) and a validated outcome satisfaction score. In total, 140 patients were invited to participate; 101 (71%) responded. ESS produces significant benefit as assessed by the GBI and satisfaction, and the benefit compares favourably with other otorhinolaryngological procedures. Greatest benefit was derived by patients undergoing surgery for polyp disease. Patients whose cardinal preoperative symptom was nasal obstruction or headache tended to report higher benefit. Co-existent asthma, allergic rhinitis or aspirin intolerance appeared not to result in a significant decrease in benefit after surgery, except in patients with non-polyp disease, who also have both aspirin intolerance and asthma. Also, for non-polyp disease, postoperative medication with nasal steroids or antihistamines does not appear to influence benefit.

Abstract
Philosophical counseling is a diverse and burgeoning type of mental health service delivery. Despite competing approaches to theory and practice, the field has largely strayed from an ethical critique of its methodology and counselor training requirements. This article outlines several ethical considerations and training recommendations that are proposed to bolster the quality and effectiveness of philosophical practice. As philosophical counseling gains increasing recognition in North America, recently established national organizations in philosophical practice may profit from revisiting their interim codes for professional conduct. Proposed training suggestions for counselor preparation my further assist institutions and board-regulated agencies in establishing competent and acceptable standards of client care.

Abstract
AIMS To assess the possible role of certain coagulation factors and associated genetic polymorphisms in families in which coronary disease has occurred prematurely. METHODS AND RESULTS One hundred and eighty-five healthy male relatives aged 65 or less were recruited following the identification of 125 patients with confirmed, premature coronary artery disease and compared to a control group of 185 healthy, age-matched volunteers. None of the control subjects had a personal or family history of coronary artery disease. The relatives and controls were similar in terms of conventional coronary artery disease risk factors. Fibrinogen levels were elevated in relatives compared with controls and remained higher after adjustment for significant correlates, 3.0 g.l(-1) (2.9-3.1) vs 2.8 g.l(-1) (2.8-2.9),P =0.004. Factor VII coagulant activity and von Willebrand factor antigen did not differ between the groups nor were there any differences in genotype frequency for the fibrinogen beta-455 G/A polymorphism or the factor VII promoter deletion/insertion and Arg-Gln coding polymorphisms. CONCLUSIONS A significant increase in fibrinogen levels was demonstrated in the healthy, male, first-degree relatives of patients with severe coronary artery disease. Fibrinogen may be of particular importance in subjects who, other than their family history, appear to be at low risk in terms of conventional coronary artery disease risk factors.

Abstract
Live attenuated lentiviruses are potentially effective candidate HIV vaccines; however, delivery of these viruses in the field would be problematic. Delivery of attenuated lentiviruses as proviral DNA would be a simple means of immunization, but the efficiency of this method of delivery is not known. In this study, macaques were readily infected following inoculation of plasmid DNA encoding proviral simian immunodeficiency virus (SIVmac239), whether given i.m. (300 microg) or epidermally (15 microg), with all four animals succumbing to AIDS at a mean of 26 weeks following inoculation. Using a human skin explant model, we found that the 50% infectious dose (ID50) of proviral SIV or HIV-1 plasmid may be as low as 1 microg when delivered to skin by gold particle bombardment using a gene gun. An infectious proviral clone of SIV mac239 with a 105 bp deletion in the 3' nef/LTR overlap region was engineered (SIVsbbc delta3), analogous to the initial common nef/LTR deletion in HIV-1 strains isolated from an Australian cohort of long-term slow-progressors. Two further macaques were also readily infected with SIVsbbc delta3 after i.m. injection of 300 microg of highly purified plasmid DNA. Unexpectedly, in one macaque inoculated with SIVsbbc delta3 DNA, SIV strains isolated three to six weeks after infection had completely repaired the nef/LTR deletion with wild-type sequence, and eventually progressed to AIDS. The mechanism used to rebuild this deletion with wild-type sequence, presumably derived from an intact 5' LTR, is unclear, but possibilities include RNA read-through errors from the plasmid DNA and recombination with residual plasmid DNA at the inoculation site.

Abstract
Little is known about the functions of the matrix (M) protein of respiratory syncytial virus (RSV). By analogy with other negative-strand RNA viruses, the M protein should inhibit the viral polymerase prior to packaging and facilitate virion assembly. In this study, localization of the RSV M protein in infected cells and its association with the RSV nucleocapsid complex was investigated. RSV-infected cells were shown to contain characteristic cytoplasmic inclusions. Further analysis showed that these inclusions were localization sites of the M protein as well as the N, P, L and M2-1 proteins described previously. The M protein co-purified with viral ribonucleoproteins (RNPs) from RSV-infected cells. The transcriptase activity of purified RNPs was enhanced by treatment with antibodies to the M protein in a dose-dependent manner. These data suggest that the M protein is associated with RSV nucleocapsids and, like the matrix proteins of other negative-strand RNA viruses, can inhibit virus transcription.

Abstract
Attention-deficit hyperactivity disorder (ADHD) is a highly heritable, common psychiatric disorder of childhood that probably involves several genes. There are several lines of evidence suggesting that the nicotinic system may be functionally significant in ADHD. First, nicotine promotes the release of dopamine and has been shown to improve attention in adults with ADHD, smokers, and nonsmokers. Second, ADHD is a significant risk factor for early initiation of cigarette smoking in children and maternal cigarette smoking appears to be a risk factor for ADHD. Finally, animal studies in rats and monkeys also suggest that nicotine may be involved in attentional systems and locomotor activity. The nicotinic system has previously been studied in schizophrenia where the neuronal nicotinic acetylcholine receptor alpha 7 subunit gene (CHRNA7) has been implicated in decreased P50 inhibition and attentional disturbances in patients with schizophrenia and in many of their nonschizophrenic relatives. Three known microsatellite markers (D15S165, D15S1043, and D15S1360) near the nicotinic acetylcholine alpha 7 receptor gene, CHRNA7, were studied in 206 ADHD parent-proband trios of children aged 5-16 with ADHD according to DSM-IV criteria. Children with known major medical or psychiatric conditions or mental retardation (IQ < 70) were excluded from the study. Markers D15S165 and D15S1360 were in linkage disequilibrium. The extended Transmission Disequilibrium Test analyses demonstrated no evidence that variation at the microsatellite markers D15S1360, D15S1043, and D15S165 influences susceptibility to ADHD. However, it remains possible that the CHRNA7 gene and other nicotinic system genes may be involved in conferring susceptibility to ADHD.

Abstract
This article presents an introduction to the history of Indian psychiatry. It suggests that this history can be divided into four main periods, 1795 to 1857, 1858 to 1914, 1914 to 1947 and 1947 to the present day. The focus of the piece is on the periods 1858-1914 and 1914-1947, as it traces the main trends and developments of the colonial era and argues that the foundations of modern psychiatry in India were laid down in the period of British rule. A brief consideration of the post-Independence period suggests that the patterns established in the years of British rule have continued to influence the psychiatric system of modern India. Research for these conclusions is based on extensive archival work in Indian mental health institutions and in Indian records offices, as well as work conducted at the National Library of Scotland in Edinburgh and at the India Office Library, the Wellcome Institute Library and the London School of Hygiene and Tropical Medicine.
