Impact of Current and Past Intimate Partner Violence on Maternal Mental Health and Behaviour at 2 Years After Childbirth: Evidence from the Pacific Islands Families Study
Authors: Gao Wanzhen , Paterson Janis , Abbott Max , Carter Sarnia , Iusitini Leon , McDonald-Sundborn Gerhard 
Published: February 2010

Objective: The present study examined the association between maternal intimate partner violence (IPV) at 6 weeks and 24 months postpartum and maternal health problems in a cohort of Pacific families with 2-year-old children in New Zealand. Methods: Data were gathered from the Pacific Islands Families Study. Mothers of a cohort of Pacific infants born in Auckland, New Zealand during 2000 were interviewed when the children were 6 weeks and 24 months of age. There were 828 mothers cohabiting in married or de facto partnerships who completed measures of IPV, mental health, and health-related behaviour such as smoking and high-risk alcohol use at both data points. The main statistical method used was logistic regression analysis. Results: Compared to mothers who did not experience physical violence at either data point, the odds of reporting psychological distress were 2.42 (95% confidence interval (CI) = 1.07–5.44) for those experiencing physical violence at 6 weeks only, 3.47 (95%CI = 1.75–6.86) for those experiencing physical violence at 24 months only, and 3.84 (95%CI = 1.78–8.30) for those experiencing physical violence at both data points after controlling for sociodemographic factors. Mothers experiencing verbal aggression or physical violence at both data points were more likely to report smoking or high-risk alcohol use at 24 months than those who did not, but the associations were no longer significant after controlling for sociodemographic factors. Conclusion: Being a victim of intimate partner physical violence at any time (past, recent and repeated) may contribute to an increase in maternal psychological distress. Health-related behaviours such as smoking and high-risk alcohol use at 24 months postpartum may to some degree be attributable to repeated victimization of physical violence and verbal aggression, but the relationships are not convincing and deserve further research in longitudinal studies.
Beginning to teach the end: the importance of including discharge from aphasia therapy in the curriculum
Authors: Hersh Deborah , Cruice Madeline 
Published: February 2010

Background: Discharging clients with long‐term aphasia from therapy services constitutes a challenging dilemma for practising clinicians for a multitude of reasons. Although discharge was raised and discussed as a contentious issue in the field of aphasiology ten years ago, it remains an aspect of practice which is complex and underexplored. We are only a little more enlightened now than then on how to address this issue in relation to professional education and practice.Aims: This paper draws on a single case study of a man with aphasia, his wife, and treating clinician, taken from a substantial research study, to highlight awareness of how communication, choice and differing perceptions of goals of therapy influence the experience of the discharge process. The case serves as the context for addressing a gap in the university curriculum around teaching about discharge practice in the context of long‐term aphasia.Methods & Procedures: This paper describes how university and practice educators could include discharge issues in students' learning by teaching discharge in context, addressing it in formal university lessons as well as through work‐based learning opportunities in clinical placements, and by scaffolding learning using graduated learning outcomes over the different stages of the students' programme.Main contribution: This paper provides practical suggestions to guide the inclusion of discharge in teaching about communication disorders generally, and specifically in relation to long‐term aphasia. Discharge needs to be appreciated within the context of the entire intervention process, with good practice modelled in both university and workplace settings. We propose that it is learned in association with stages of decision‐making, duty of care, documentation, goal setting, continuous therapy evaluation, clinical reasoning, professional communication with clients, ethical behaviour, and evidence‐based practice.Conclusions & Implications: Bringing discharge practice from the realm of implicit knowledge to one that can be examined and discussed in an explicit manner should help reduce anxieties about discharge for new clinicians, help to clarify and improve the discharge approaches used by clinicians and lead to better discharge experiences for clients.
Surgical management of World Health Organization Grade II gliomas in eloquent areas: the necessity of preserving a margin around functional structures
Authors: Gil-Robles Santiago , Duffau Hugues 
Published: February 2010

Object
Recent surgical studies have demonstrated that the extent of resection is significantly correlated with median survival in WHO Grade II gliomas. Consequently, thanks to advances in intraoperative functional mapping, the authors questioned whether it is actually necessary to leave a “security” margin around eloquent structures.

Methods
The authors first reviewed the classic literature, especially that based on epilepsy surgery and functional neuroimaging techniques, which led them to propose the rule of a security margin. Second, they detailed new developments in the field of intrasurgical electrical mapping, especially with regard to subcortical stimulation of the projection and long-distance association pathways. On the basis of these advances, the removal of gliomas according to functional boundaries has recently been suggested, with no margin around eloquent structures.

Results
Comparative results showed that the rate of permanent deficit was similar with or without a security margin, that is, < 2%. However, a higher rate of transient neurological worsening in the immediate postsurgical period was associated with the absence of a margin, with recovery following adapted rehabilitation. On the other hand, the extent of resection was in essence improved with no margin.

Conclusions
This no-margin technique, based on the subpial dissection, and the repetition of both cortical and subcortical stimulation to preserve eloquent cortex as well as the white matter tracts (U-fibers, projection pathways, and long-distance connectivity) allow optimization of the extent of resection while preserving the quality of life (despite transitory impairment) thanks to mechanisms of brain plasticity.
Cerebral microdialysis and intracranial pressure monitoring in patients with idiopathic normal-pressure hydrocephalus: association with clinical response to extended lumbar drainage and shunt surgery
Authors: Eide Per K. , Stanisic Milo 
Published: February 2010

Object
This study was performed in patients with idiopathic normal-pressure hydrocephalus (iNPH) to monitor cerebral metabolism with microdialysis (MD) and intracranial pressure (ICP) readings, and relate to the clinical responses to extended lumbar drainage (ELD) and shunt surgery.

Methods
The baseline levels of MD metabolites and ICP were monitored overnight in 40 consecutive patients with iNPH. In a subset of 28 patients, monitoring was continued during 3 days of ELD. Thirty-one patients received a ventriculoperitoneal shunt. The clinical severity of iNPH was determined before and then 3 and 6–12 months after shunt surgery.

Results
Altered levels of MD markers (lactate, pyruvate, lactate/pyruvate ratio, glutamate, and/or glycerol) were seen in all patients at baseline; these improved during ELD. Despite normal static ICP (mean ICP), the pulsatile ICP (the ICP wave amplitude) was increased in 24 patients (60%). Only the level of the ICP wave amplitude differentiated the ELD and/or shunt responders from nonresponders.

Conclusions
The MD monitoring indicated low-grade cerebral ischemia in patients with iNPH; during ELD, cerebral metabolism improved. The pulsatile ICP (the ICP wave amplitude) was the only variable differentiating the clinical responders from the nonresponders. The authors suggest that the pulsatile ICP reflects the intracranial compliance and that CSF diversion improves the biophysical milieu of the nerve cells, which subsequently may improve their biochemical milieu.
Complete removal of vagus nerve stimulator generator and electrodes
Authors: Ortler Martin , Unterhofer Claudia , Dobesberger Judith , Haberlandt Edda , Trinka Eugen 
Published: February 2010

Vagus nerve stimulation has become widely used in the palliative treatment of refractory epilepsy. Removal of a vagus nerve stimulator may be desirable or even necessary due to lack of efficacy, intolerable side effects, signs of infection, or failure of the device. Unless the lead or the helical electrodes are defective, only the generator is explanted and the electrodes are usually left behind for fear of damaging nerve or surrounding structures. The authors review their experience with complete removal of the stimulating electrodes and pacemaker-like generator device in 9 consecutive patients, 3 of whom were children.
Using microsurgical techniques, the authors were able to completely remove the stimulator, including electrodes in all patients. All nerves remained morphologically intact. One case of temporary and one of permanent clinically silent ipsilateral vocal cord paresis were observed.
Do baclofen pumps influence the development of scoliosis in children?
Authors: Burn Sasha C. , Zeller Reinhard , Drake James M. 
Published: February 2010

Object
Intrathecal baclofen is an effective treatment for spasticity in patients with cerebral palsy. There has been increasing concern, however, that intrathecal baclofen may accelerate the development of scoliosis in this population. To this end, the authors reviewed their population of pediatric patients with baclofen pumps to assess the incidence of scoliosis.

Methods
This was a retrospective chart and radiology review of all pediatric patients with baclofen pumps. Cobb angles were measured preoperatively and on follow-up images.

Results
Of 38 patients identified, 32 had adequate data available for inclusion in the study (16 with cerebral palsy, 7 with dystonic cerebral palsy, 4 with head injury, and 5 with other diagnoses). The mean age at pump insertion was 10.6 years and the mean follow-up period was 31 months (range 1–118 months). The mean annual Cobb angle progression was 19° (range 0–68°, median 12°).

Conclusions
In the authors' group of patients there was notable development and progression of scoliosis at a greater than previously reported rate for the same patient population, and also greater than previously reported patients with intrathecal baclofen pumps. The largest possible confounding factor in this study was the insertion of the pump before skeletal maturity and therefore coinciding with the time when scoliosis may be developing naturally. A prospective study is recommended to gather further data on the development of scoliosis in this particular population with intrathecal baclofen pumps.
Endoscopic third ventriculostomy in the treatment of childhood hydrocephalus in Uganda: report of a scoring system that predicts success
Authors: Warf Benjamin C. , Mugamba John , Kulkarni Abhaya V. 
Published: February 2010

Object
In Uganda, childhood hydrocephalus is common and difficult to treat. In some children, endoscopic third ventriculostomy (ETV) can be successful and avoid dependence on a shunt. This can be especially beneficial in Uganda, because of the high risk of infection and long-term failure associated with shunting. Therefore, the authors developed and validated a model to predict the chances of ETV success, taking into account the unique characteristics of a large sub-Saharan African population.

Methods
All children presenting with hydrocephalus at CURE Children's Hospital of Uganda (CCHU) between 2001 and 2007 were offered ETV as first-line treatment and were prospectively followed up. A multivariable logistic regression model was built using ETV success at 6 months as the outcome. The model was derived on 70% of the sample (training set) and validated on the remaining 30% (validation set).

Results
Endoscopic third ventriculostomy was attempted in 1406 patients. Of these, 427 were lost to follow-up prior to 6 months. In the remaining 979 patients, the ETV was aborted in 281 due to poor anatomy/visibility and in 310 the ETV failed during the first 6 months. Therefore, a total of 388 of 979 (39.6% and [55.6% of completed ETVs]) procedures were successful at 6 months. The mean age at ETV was 12.6 months, and 57.8% of cases were postinfectious in origin. The authors' logistic regression model contained the following significant variables: patient age at ETV, cause of hydrocephalus, and whether choroid plexus cauterization was performed. In the training set (676 patients) and validation set (303 patients), the model was able to accurately predict the probability of successful ETV (Hosmer-Lemeshow p value > 0.60 and C statistic > 0.70). The authors developed the simplified CCHU ETV Success Score that can be used in the field to predict the probability of ETV success.

Conclusions
The authors' model will allow clinicians to accurately identify children with a good chance of successful outcome with ETV, taking into account the unique characteristics and circumstances of the Ugandan population.
The natural history of pineal cysts in children and young adults
Authors: Al-Holou Wajd N. , Maher Cormac O. , Muraszko Karin M. , Garton Hugh J. L. 
Published: February 2010

Object
The authors reviewed their experience with pediatric pineal cysts to define the natural history and clinical relevance of this common intracranial finding.

Methods
The authors identified all patients with pineal cysts who had been clinically evaluated at their institution over an 11.5-year interval and were < 25 years of age at the time of diagnosis. All inclusion criteria were met in 106 patients, and included repeated MR imaging as well as repeated clinical evaluation over at least a 6-month interval.

Results
The mean age at diagnosis was 11.7 ± 7.2 years. Forty-two patients were male and 64 were female. On follow-up MR imaging evaluation at a mean interval of 3.0 years from the initial study, 98 pineal cysts had no increase in size and no change in imaging appearance. Six pineal cysts increased in size and 2 others had a change in imaging characteristics without associated growth. Younger age was associated with cyst change or growth on follow-up imaging (p = 0.02). The mean age of patients with cysts that changed or grew was 5.5 years, and the mean age of patients with stable pineal cysts was 12.2 years. Initial cyst size and appearance on MR imaging were not significant predictors of growth or change in imaging appearance at follow-up. Similarly, the patient's sex was not a significant predictor of growth or change in imaging characteristics.

Conclusions
Follow-up imaging and neurosurgical evaluation may be considered optional in older children with pineal cysts.
Relative contributions of the middle meningeal artery and superficial temporal artery in revascularization surgery for moyamoya syndrome in children: the results of superselective angiography
Authors: King James A. J. , Armstrong Derek , Vachhrajani Shobhan , Dirks Peter B. 
Published: February 2010

Object
The authors used postoperative superselective angiography to assess the relative contributions of the middle meningeal artery (MMA) and the superficial temporal artery (STA) to revascularization following surgery for moyamoya syndrome in children.

Methods
Using the neurosurgical database at the Hospital for Sick Children, the authors reviewed the clinical and pre- and postoperative angiographic records obtained in patients with moyamoya syndrome undergoing superselective angiography. Patients were 16 years of age or younger and were undergoing revascularization surgery for moyamoya syndrome during the study period. Lateral internal carotid artery, external carotid artery, STA, and MMA angiograms were analyzed in the late arterial phase to assess the relative contributions of the STA and MMA to overall revascularization as determined by the external carotid artery injection.

Results
The total moyamoya surgical revascularization experience at the Hospital for Sick Children over a 12-year period (May 1996–December 2008) comprised 33 patients (20 girls and 13 boys) undergoing a total of 50 craniotomies. A decision was made in 2001 to perform superselective angiography postoperatively in patients with moyamoya syndrome. Superselective angiography was identified to have been performed postoperatively in 12 patients and 18 treated hemispheres, and it demonstrated that the MMA contributed more significantly than the STA in 11 (61%) of the 18 hemispheres.
Seven patients were Asian, 3 patients had neurofibromatosis Type 1, 1 had Down syndrome, and 2 had no apparent risk factors (1 patient was Asian and had neurofibromatosis Type 1). Stroke had occurred in 58% of patients and transient ischemic attacks in 50% prior to surgery. Within the first 30 days of surgery, there were 2 episodes of stroke (11.7% per surgically treated hemisphere and 18.2% per patient). Seventy-eight percent of hemispheres surgically treated exhibited excellent revascularization (Matsushima Grade A) on follow-up angiography, and there were no strokes documented in any patients more than 1 month after surgery, in a long-term follow-up of mean 4.1 years.

Conclusions
The contributions of the MMA to revascularization after pial synangiosis for moyamoya syndrome are significant and may frequently exceed the contribution of the STA when surgery is performed with preservation of dural vasculature and dural inversion.

AbstractModern geoinformatic techniques allow the automated creation of detailed glacier inventory data from glacier outlines and digital terrain models (DTMs). Once glacier entities are defined and an appropriate DTM is available, several methods exist to derive the inventory data (e.g. minimum, maximum and mean elevation; mean slope and aspect) for each glacier from digital intersection of both datasets. Compared to the former manual methods, the new grid-based statistical calculations are very fast and reproducible. The major aim of this contribution is to help in standardizing the related calculations to enhance the integrity of the Global Land Ice Monitoring from Space (GLIMS) database. The recommendations were prepared by a working group and also contribute to the European Space Agency project GlobGlacier. The document follows the former UNESCO manual for the production of the World Glacier Inventory published in 1970, identifies the potential pitfalls, and describes the differences from the former methods of compilation. The online background material for this paper (see http://www.glims.org) contains example scripts for calculation of each parameter and will be updated when required.
A more complete version of the World Glacier Inventory
Authors: Cogley J. Graham 
Published: February 2010

AbstractThe World Glacier Inventory (WGI) was conceived half a century ago as an activity to be completed during the International Geophysical Year, 1957/58. It consisted until very recently of nearly 70 000 glacier records covering slightly less than one-quarter of the glacier ice outside the ice sheets. A complete WGI must be a compromise if it is to be available and usable soon. A more complete version, called WGI-XF, is available and usable now and contains records for just over 131 000 glaciers and nearly half of the global extent of ice. The additional glaciers come mainly from the assimilation of existing inventories but also from rescuing inventories that have been lost and from new inventories in Canada and the Subantarctic. In WGI-XF, the XF stands for ‘extended format’, flagging the fact that WGI-XF conforms to a set of explicit specifications which enhance usefulness by eliminating low-level inconsistencies. Two important features are nominal glaciers and glacier complexes. A nominal glacier, of which there are about 5000 in WGI-XF, is one about which little is known other than its existence and approximate location. A glacier complex is one or more contiguous glaciers. This term embodies the idea, which is not new, that inventories can be preliminary, based upon vector outlines which await subdivision by trained glaciologists. Many regional studies have found that measurements of changes in single glaciers require accurate work and painstaking quality control. WGI-XF is not assuredly reliable as a source for such detailed work, but there are several other subjects in which less detail would be a price worth paying for more complete coverage. Incomplete information about the dates of imagery and maps is a hindrance to analysis, and the recovery of dates from metadata should have high priority.
Le gisement paléolithique moyen de faciès cambrésien de Gouzeaucourt (Nord). Essai de reconstitution des chaînes opératoires

Published: February 2010

The open air site of Gouzeaucourt has got several archeological levels included in a sequence of the middle Pleistocene and old loesses.
The first typological and technological studies used to present this industry with a lot of acheulian hand axes, a good representation of middle paleolithic flake tools and the absence of Levallois technique. A reconstitution attempt of the sequence of reduction is added, which underlines the ways and possibilities to produce flakes and tools from various stands.
