The reflectance spectra of natural and man‐made surfaces are highly constrained. Statistical analyses have been conducted that confirm that the surface reflectance spectra form a set of band‐limited functions with a frequency limit of approximately 0.02 cycles/nm. The reflectance spectra can be represented by a linear‐model framework and are adequately described by 6‐12 basis functions. However, the spectral properties of surfaces are not so constrained as to allow the human visual system to recover the surface properties from cone excitations. Furthermore, trichromatic colour devices such as scanners and cameras can only capture illumination‐specific colour information.

The aim of the review is to investigate the reasons for referral to this child and adolescent mental health (CAMH) service and determine whether these had been met by the service.

This is a retrospective case note analysis that was conducted of 66 referrals to CAMHS for children and young people serving a rural community of 132,000. Case notes were selected by the NHS CAMHS manager based on referrals during the pre-defined date set. Of the 66 referrals to CAMHS, 19 were not included in the analysis because they had not been accepted into the service. Data were analysed on the remaining 47 cases who were referred, accepted into the service and had been offered an assessment by the service.

General practitioners represented the most frequent health care practitioner to refer to the service (n = 33, 70.2%). Self harm, suicidal intent, thoughts or overdose represented the highest percentage of referrals to the CAMHS service (38.3%); depression, low mood and sadness represented the next highest figure (19%) and anxiety and depression (10.6%) broadly speaking 68% of referrals related to low mood. Out of the 44 cases that were examined, 14/44 (32%) were referred back to the GP and no specific intervention was provided. Interventions provided to five cases were unspecified.

A number of opportunities for developing the service that allowed for a focus on the core business of helping children and young people with low mood were identified. One of the limitations of this retrospective review was the time frame selected because it had been identified as a particularly high period for referral into the service and may not have been representative of the usual trend.

This informed a training strategy and resource allocation and a redefinition of discrete roles within the service.

This study highlighted the evidence about where the demand was on this service and hence the requirement to focus on their core business. This evidence generated by the review prompted a redirection of resources within the service. Additional reflections and discussion informed the development of a new training strategy and a redefinition of discrete roles within the service.

A review of literature concerning the over‐representation of young, African‐Caribbean males within secure psychiatric services.

The purpose of this paper is to consider mental health issues in children and adolescents with chronic illness or health conditions, including their treatment, and issues related to delivery of services.

A selective review of the literature was conducted to highlight significant mental health issues and their treatment in youth with various types of chronic illness.

A significant portion of youth experience mental health problems related to their chronic health conditions. While evidence-based treatments are available to address these problems, significant barriers exist that impede the delivery of psychological and behavioral interventions for many youth.

More controlled studies are needed to demonstrate the effectiveness and cost offset of delivering psychological and behavioral interventions for the population of youth with various types of chronic health conditions, particularly in clinical and community settings.

Policy reform can ensure that mental health issues are effectively addressed for children with chronic illness. Policy is needed that promotes integrated health care, whereby psychological and behavioral interventions are delivered in health care settings along with medical interventions to reduce barriers to care.

Significant numbers of children and adolescents have chronic health conditions and many experience mental health problems related to their conditions. While evidence-based treatments are available to address these problems, significant barriers impede the delivery of psychological and behavioral interventions for many youth. Health care policy promoting integrated health care to deliver psychological and behavioral interventions in health care settings along with medical interventions should reduce barriers to care and improve both physical and mental health outcomes for youth.
