Sensitivity and specificity of the sensory collapse test for nerve entrapment syndrome in the upper extremity.

Objectives: Several prospective blinded studies have found poorer sensitivity for the sensory collapse test than reported by Susan E Mackinnon's team. However, the blinded examiner had no knowledge of the patient's clinical presentation, or even of the purpose of the test. In these conditions, it seems difficult to perform the sensory collapse test correctly.

Vascularized hemi-hamate graft: Anatomic description of a novel pedicled osteo-chondro-ligamentous flap for proximal scaphoid reconstruction.

Scaphoid proximal pole destruction remains a surgical challenge owing to its high propensity for nonunion and osteonecrosis. The hemi-hamate graft has shown promising results in addressing this issue. However, long-term results of non-vascularized composite grafts remain uncertain.

Secondary complications in Wassel II & IV thumb duplication: a comprehensive review of preventive measures.

Objectives: Thumb duplication is one of the most challenging pediatric reconstructive hand surgeries. Wassel types II and IV are the most frequent, but also the most complex reconstructions as the duplication arises at the joint level. Ablation and reconstruction, the most widely used technique, aims at achieving a stable, well-aligned, mobile and esthetically acceptable thumb.

Frostbite in the Pediatric Population: A Comprehensive Review and a Prospective Canadian Survey.

Introduction: Frostbite in the pediatric population, where skeletal maturity has not been achieved, can have important repercussions on subsequent growth. Yet, the optimal management of frostbite injuries in children remains vague. This review aims to summarize the current evidence for frostbite management in children and understand Canadian practice trends on this topic.

The Montreal Plastic Surgery Residency Bootcamp: Structure and Utility.

Transitioning from medical school to surgical residency is a difficult endeavor. To facilitate this period, the University of Montreal's plastic surgery program developed and implemented an intensive 1-month bootcamp rotation. It is the only one of its kind and length amongst plastic surgery residency programs in North America.

It is all about form and function: a new approach to giant neonatal sacrococcygeal teratomas.

Introduction: Giant sacrococcygeal teratomas (GSCTs) involve severe deformation of the buttock region in addition to potential functional impacts. Little interest has been given to improving the aesthetic post-operative appearance in children with these tumours.

Methods: We describe a new technique for immediate reconstruction of GSCTs using buried dermal-fat flaps and a low transverse scar in the infragluteal fold.

Changes to acute-care hospitalizations among Indigenous children and youth: Results from the 2006 and 2011 Canadian Census Health and Environment Cohorts.

Background: This study described the differences in the hospitalization rates of First Nations children and youth living on and off reserve, Inuit children and youth living in Inuit Nunangat (excluding Nunavik), and Métis children and youth, relative to non-Indigenous children and youth and examined rate changes across 2006 and 2011.

Data And Methods: The 2006 and the 2011 Canadian Census Health and Environment Cohorts provided five years of hospital records that Statistics Canada linked to peoples' self-reported Indigenous identity as recorded on the census. Causes of hospitalizations were based on the most responsible diagnosis coded according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada, aggregated by chapter code.

Readability and Quality Assessment of Online Materials for Syndactyly Release.

Unlabelled: Syndactyly is one of the most common congenital hand malformations, involving an abnormal fusion of digits and with treatment varying according to its complexity. The internet has become a primary source of information for both families and patients with congenital hand anomalies. The purpose of this study was to evaluate both the readability and quality of available web content for syndactyly, using validated instruments.

Do cancer incidence and mortality rates differ among ethnicities in Canada?

Background: Cancer incidence rates have been shown to vary by ethnicity, and the increasing awareness of and interest in reporting ethnic health inequalities have been growing internationally. The objective of this study was to assess cancer incidence and mortality rates by ethnicity in Canada.

Data And Methods: The study used the 2006 Canadian Census Health and Environment Cohort, linked to the Canadian Cancer Registry and the Canadian Vital Statistics-Death Database, to determine cancer cases and mortality from 2006 to 2016.

Restoration of the first dorsal interosseous muscle.

Motor dysfunction of the 1 dorsal interosseous (DIO) muscle is typically observed in low and high ulnar nerve palsy. This causes weak thumb-index pinch, which can be disabling for the patient. Various reconstructive techniques have been described; however, the choice often depends on the surgeon's experience, the presence of associated neurovascular and musculotendinous injuries, as well as the requirements of the palliative surgery schedule.

Acute-care hospitalizations among First Nations people, Inuit and Métis: Results from the 2006 and 2011 Canadian Census Health and Environment Cohorts.

Background: The objective of this study was to describe sex-specific hospitalization rates among Indigenous people in Canada (excluding Quebec), separately for First Nations people living on and off reserve, Inuit living in Inuit Nunangat (excluding Nunavik), Métis, and the non-Indigenous population.

Data And Methods: The 2006 and 2011 Canadian Census Health and Environment Cohorts (CanCHECs) were used, allowing hospital records to be examined by Indigenous identity as reported on the census. Five years of hospitalization data were used for each CanCHEC.

Life expectancy of First Nations, Métis and Inuit household populations in Canada.

Background: The Truth and Reconciliation Commission of Canada has called upon the federal government to provide data on a number of health indicators, including life expectancy among First Nations people, Métis and Inuit. In Canada, estimating the life expectancy of Indigenous populations is methodologically challenging since death registrations do not usually collect information on whether the deceased was Indigenous. For the first time in Canada, a series of census-mortality linked datasets has been created that can be used to estimate life expectancies among Indigenous household populations enumerated by a census.

Smoking correlates among Inuit men and women in Inuit Nunangat.

Background: Although rates of daily smoking among Inuit have been decreasing since 1991, Inuit are still much more likely to smoke relative to the Canadian population as a whole. However, little population-based empirical research has identified characteristics associated with cigarette use among this population.

Data And Methods: Based on data from the 2012 Aboriginal Peoples Survey, sex-specific logistic regression analyses, informed by an Inuit social determinants of health framework, described associations between current smoking and selected socio-demographic characteristics among Inuit men and women aged 18 or older who resided in Inuit Nunangat.

Family networks and health among Métis aged 45 or older.

Background: Social networks are important for promoting and maintaining health and well-being. Social networks, including family and friendship ties, are sources of emotional, practical and other support that enhance social participation and help combat isolation and loneliness. Aboriginal seniors have been identified as a population at risk of social isolation.

Closed Digital Artery Injury in Children: A Case Report and Review of the Literature.

Closed digital artery injury is a very rare phenomenon, even more so in children, with only 5 cases reported in the literature. We report a case of closed digital arterial interruption in a child after crush injury to the left hand. We further discuss possible etiologies and describe adequate management as found in the pertinent literature.

Acute care hospitalization of Aboriginal children and youth.

Background: Research that has examined Aboriginal children's hospitalization rates at the national level has been limited to analyses of areas with large percentages of Aboriginal residents, rather than of Aboriginal individuals. This study uses linked census and administrative data to describe hospitalization patterns among children and youth aged 0 to 19, by Aboriginal identity, for all provinces and territories except Quebec.

Data And Methods: The 2006 Census was linked to the 2006/2007-to-2008/2009 Discharge Abstract Database, which contains hospital records from all acute care facilities (except Quebec).

Smoking prevalence among Inuit in Canada.

Using data from the 1991, 2001 and 2012 Aboriginal Peoples Survey, this study examines the prevalence of smoking among Inuit aged 15 or older, by location of residence, sex and age group. Overall, the prevalence of daily smoking was significantly lower in 2012 than in 1991; this was true for Inuit living inside and outside Inuit Nunangat, for men and women, for most age groups, and for those in all Inuit regions except Nunavik. The average number of cigarettes smoked per day by daily smokers decreased steadily and significantly over time, except among those living outside Inuit Nunangat or in Nunavik, and those aged 55 or older.

Acute care hospitalization by Aboriginal identity, Canada, 2006 through 2008.

Background: National data about acute care hospitalization of Aboriginal people are scarce. This study addresses that information gap by describing patterns of hospitalization by Aboriginal identity for leading diagnoses for all provinces and territories except Quebec.

Data And Methods: The 2006 Census was linked to the 2006/2007-to-2008/2009 Discharge Abstract Database, which contains hospital records from all acute care facilities in Canada (excluding Quebec).

Validation of the 10-item Kessler Psychological Distress Scale (K10) in the 2012 Aboriginal Peoples Survey.

Background: The 10-item Kessler Psychological Distress Scale (K10) is a short measure of non-specific psychological distress, which has been shown to be a sensitive screen for the Diagnostic and Statistical Manual of Mental Disorders criteria for anxiety and mood disorders. The scale has yet to be validated as a measure of psychological distress for Aboriginal peoples in Canada.

Data And Methods: Using the 2012 Aboriginal Peoples Survey (APS), this study examined the psychometric properties of the K10 for First Nations people living off reserve, Métis, and Inuit aged 15 or older.

Housing and health among Inuit children.

Background: Housing conditions have been associated with child health. Inuit children are generally in poorer health than other Canadian children. They are also more likely to live in crowded households, in dwellings that need major repair, and to be exposed to second-hand smoke in the home.

Comparison Between Surgical Resection and Stereotactic Radiosurgery in Patients with a Single Brain Metastasis from Non-Small Cell Lung Cancer.

Background: The management of patients with single brain metastasis (BM) from non-small cell lung cancer (NSCLC) is controversial. Surgical resection (SR) with adjuvant irradiation and stereotactic radiosurgery (SRS) are performed in the treatment of such lesions. This study compared both modalities in terms of tumor control and survival.
