Transition to adult care for young people with cerebral palsy

Cerebral palsy (CP) is associated with a high burden of comorbid respiratory disease subsequent to multiple risk factors associated with increasing levels of disability. Correspondingly, respiratory disease is the leading cause of death in CP, including amongst young people who are transitioning or who have just transitioned between paediatric and adult healthcare services. Therefore, consideration of both preventive and therapeutic respiratory management is integral to transition in patients with CP, as summarised in this review.     

Health care and its costs for children with perinatally acquired HIV infection

Objective : To describe survival patterns, use of health services and related costs for Australian children with perinatally acquired human immunodeficiency virus (HIV) infection.
Methodology : A retrospective cross-sectional survey was made of 20 children with HIV infection (91% of those diagnosed) and 13 children with maternal antibodies who subsequently seroreverted, treated at 10 medical centres. Details of disease progression and use of health services were obtained from hospital medical records. Monthly costs for three phases of infection were estimated by linking service usage rates with estimates of the unit cost of each service. The average lifetime cost was estimated by combining monthly costs and phase duration estimates from the literature.
Results : Patterns of disease progression were similar to those reported internationally, with a median survival of 8 years. Use, of health services increased with severity of illness. Mean monthly costs were $120 per month (1992 Australian dollars) for children with maternal antibodies who subsequently seroreverted, $320 per month for children with HIV infection but no acquired immunodeficiency syndrome (AIDS)-defining illness, and $1830 per month for children with AIDS. The present value of total lifetime cost for a child with HIV infection was $48174,46% of which was for treatment of AIDS.
Discussion : The mean lifetime cost for a perinatally infected child was just over half that for a man with HIV in Australia. Health service usage and costs were lower for Australian than American children with HIV.     

Cutaneous melanoma in adolescents and young adults

Cutaneous melanoma is rare in children, but has greater incidence in adolescents and young adults (AYAs). Diagnosis may be challenging due to its rarity in these age groups. Few studies have specifically addressed the topic of AYA melanoma. Though young‐age melanoma may have particular biological characteristics, available data suggest that its clinical history is similar to that of adults. However, advances in treatment of adult melanoma have not been reflected in the treatment of AYAs. There is no standard treatment, and access to clinical trials is difficult for AYAs. Further efforts are needed to overcome these issues by improving cooperation with experts on adult melanoma.     

Thyroid cancer in adolescents and young adults

In adolescents and young adults, thyroid cancer accounts for 13% of all invasive neoplasms, being three times more frequent in females, but overdiagnosis and overtreatment are common. There are two therapeutic approaches, one radical and no longer preferred in all instances, and the other conservative. Permanent complications of surgery and metabolic irradiation can affect quality of life and carry an economic burden. The overall survival rate approaches 100% for patients with differentiated thyroid cancer regardless of the extent of treatment. Medullary thyroid carcinoma is a very different entity, occurring most frequently in the context of hereditary tumor susceptibility syndromes.     

Ovarian cancer in adolescents and young adults

The diagnosis of ovarian cancer in adolescents and young adults is always challenging. Many issues exist, and most important of these may be access to care with an appropriate provider. A range of histologies occur in the ovaries, and their frequency changes markedly as patients progress from adolescence to young adulthood. The very curable germ cell tumors of adolescence slowly give way to aggressive carcinomas, which require a different treatment approach. Special consideration is needed for treatment of toxicity. In an ideal world, centers consisting of pediatric, medical, and gynecological oncologists may be the most appropriate to care for these complex and diverse patients.     

Transition of young people with respiratory diseases to adult health care

As many more young people with chronic health conditions survive well into adulthood, transition of affected young people from paediatric to adult health care is increasingly becoming the expected standard of care. Despite this, there is still little objective or long-term evidence to guide the development or deployment of developmentally appropriate transition processes or to define the precise manner in which the transfer of care should take place. Nevertheless, certain principles of transition have now received nearly universal endorsement. In this paper, the rationale for transition is discussed, practical strategies for transition are described, the existing evidence base supporting transition is reviewed and limitations in our knowledge are outlined. Ultimately, a carefully planned transition to adult health care should improve self-reliance, enhance autonomy and independence and support young people in attaining their maximum potential and meaningful adult lives.     

Injuries to adolescents and young adults

Death rates in adolescents are on the rise--the only age group for which this is true. Unintentional injuries, homicide, and suicide account for 80 per cent of all deaths in this group. The authors summarize the available morbidity and mortality data.     

Acute myelogenous leukemia in adolescents and young adults

The incidence of acute myelogenous leukemia (AML) increases progressively with age. Favorable genetic mutations are most prevalent in children, and unfavorable profiles increase proportionately in adolescents and young adults (AYA) and into later adulthood. Survival rates of AYA have improved over recent decades to 50–60%, but their accrual to clinical trials remains poor. In contrast to AYA with acute lymphoblastic leukemia, the prognostic benefit for AYA with AML enrolled in pediatric compared with adult trials is minor and only seen when different protocols are used. The distinctive needs of AYA, including intensive psychological services, call for their treatment within specialized centers that offer complex supportive care.     

Aerobic capacity in late adolescents infected with HIV and controls

OBJECTIVES: The objective of this study was to determine if aerobic capacity was diminished in late adolescents infected with HIV compared to controls matched for age, gender, and physical activity level. STUDY DESIGN: This study was a quasi-experimental cross sectional analysis. Subjects (11 female, four male) were 15 late adolescents with HIV (18 +/- 0.03 years) (CD4: 499.2 +/- 37.5 cells/mm(3), viral load: 22043 +/- 9976.6 copies/ml, haematocrit: 36.4 +/- 1.2) and 15 age, gender, and activity level matched controls (18 +/- 0.03) who underwent maximal treadmill exercise testing, while oxygen consumption, carbon dioxide production, ventilation, and ECG data were simultaneously recorded via open circuit spirometry and electrocardiography. RESULTS: Peak oxygen consumption (p < 0.003), peak treadmill stage (p < 0.003), treadmill duration (p < 0.004), and oxygen pulse (p < 0.009) were lower in those infected with HIV compared to controls. Functional aerobic impairment was observed in the late adolescents infected with HIV, pointing toward pathological limitations of the oxidative metabolic pathway. CONCLUSION: This study has demonstrated that aerobic capacity was reduced substantially in late adolescents infected with HIV, below that observed in controls. The findings suggest that this decrease in oxidative capacity was due to mechanisms other than physiologic deconditioning.
