Duplication of the lower third of the internal jugular vein--case report and surgical implications.

Duplication of the internal jugular vein is rare with a reported incidence of 0.4%. Most are located in the upper third and are almost always unilateral, duplication of the lower third is less common.

A two-minute paper-and-pencil test of symbolic and nonsymbolic numerical magnitude processing explains variability in primary school children's arithmetic competence.

Recently, there has been a growing emphasis on basic number processing competencies (such as the ability to judge which of two numbers is larger) and their role in predicting individual differences in school-relevant math achievement. Children's ability to compare both symbolic (e.g.

Development of a Childhood Attachment and Relational Trauma Screen (CARTS): a relational-socioecological framework for surveying attachment security and childhood trauma history.

Background: Current psychometric measures of childhood trauma history generally fail to assess the relational-socioecological context within which childhood maltreatment occurs, including the relationship of abusers to abused persons, the emotional availability of caregivers, and the respondent's own thoughts, feelings, and actions in response to maltreatment.

Objective: To evaluate a computerized approach to measuring the relational-socioecological context within which childhood maltreatment occurs.

Method: The psychometric properties of a Childhood Attachment and Relational Trauma Screen (CARTS) were evaluated as a retrospective survey of childhood maltreatment history designed to be appropriate for completion by adults.

Squamous cell carcinoma arising in dentigerous cysts.

We present two cases of squamous cell carcinoma (SCC) arising in dentigerous cysts. Malignant transformation in dentigerous cysts is rare giving rise to diagnostic difficulties. We propose imaging at an early stage to reduce delays in diagnosis.

Lymphatic malformations of the head and neck-current concepts in management.

Lymphatic malformations of the head and neck, also known as lymphangiomas or cystic hygromas, are a diverse group of lesions. They can be small and superficial or large and extensive, and management can be a challenge. Surgically they can be difficult to remove completely because of their poorly defined borders and the potential for damaging neighbouring structures.

Help-seeking for children with mental health problems: parents' efforts and experiences.

Parents who contacted 1 of 15 children's mental health agencies in Ontario, Canada reported on where and why they were seeking mental health services for their 4- to 17-year-old children. Parents contacted an average of four agencies (± 1.7; range = 1-14) in the previous year.

Visual recovery following optic nerve decompression for chronic compressive neuropathy.

Purpose: Visual failure due to optic nerve compression is a common indication for decompressive surgery. Most data only refer to the odds of improvement, deterioration or remaining the same. However, patients frequently wish to know more detail about the outcomes of surgery.

How parents seek help for children with mental health problems.

Parents seeking help for their child's mental health problem face a complicated system of services. We examined how parents navigate the various services available. Sixty parents contacting a children's mental health center were interviewed regarding their efforts and rationale in seeking help for their child.

Serum insulin-like growth factor-I and insulin-like growth factor binding protein-3 following chemotherapy for advanced breast cancer.

Background: Insulin-like growth factor-I (IGF-I) and IGF binding protein-3 (IGFBP-3) appear to influence the growth of breast cancer cells in vitro, and epidemiological studies suggest higher serum IGF-I levels increase the risk of breast cancer. IGF-I and IGFBP-3 have therefore been measured in women with advanced breast cancer to determine if changes in serum levels predict the response to treatment by chemotherapy.

Methods: Serum IGF-I and IGFBP-3 levels were measured in 14 patients before and after 1 week of chemotherapy.

Maternal emotional responses to preterm birth.

Mothers of 144 preterm infants with varying degrees of neonatal illness were interviewed prior to their infants' discharge from neonatal intensive care. Their major concerns were for the infants' survival rather than their own welfare. Husbands, parents, and, for members, church were seen as the major sources of support.
