Routine preoperative brain CT in resectable non-small cell lung cancer - Ten years experience from a tertiary UK thoracic center.

OBJECTIVES: Although detection of brain metastasis can change treatment intent in non-small cell lung carcinoma (NSCLC), head imaging is not routinely performed during initial staging. In our previous study, 4.8% of patients considered for surgical treatment had asymptomatic synchronous brain metastases, encouraging us to include contrast-enhanced head CT (CE-CT) in our routine staging protocol. We present results from a large cohort of potentially resectable NSCLC patients imaged irrespective of the presence of neurological symptoms. MATERIALS AND METHODS: Patients with newly diagnosed NSCLC were identified from Royal Papworth Hospital registries. Data regarding the clinical stage (7th edition TNM), neurological symptoms and imaging findings were retrieved from clinical records. RESULTS: 1074 NSCLC patients considered potentially resectable based on the initial staging CT of the chest and abdomen (stage IA-IIIB) were included. Synchronous brain metastases were detected by CE-CT in 23 patients (2.1%); the rate of positive findings increased with stage, ranging from 0.7% (IA) to 2.6% (IIIA) (p = 0.023). The majority of metastases were asymptomatic (19 of 23, 82.6%). Asymptomatic brain lesions were smaller than symptomatic (13.3 ±â€¯4.8 vs 24.8 ±â€¯8.2 mm; p < 0.01); in both groups, the most frequent location was frontal lobe. CONCLUSION: Routine CE-CT detected synchronous brain metastases in approximately 2% of NSCLC patients eligible for radical surgical treatment. The majority of the metastatic lesions were asymptomatic. With the exception of stage IA in which the detection rate is very low, CE-CT could therefore be useful in routine NSCLC staging.

Vitamin D supplementation: we must not fail our children!

There is increasing concern that vitamin D deficiency poses a major health problem for children. Deficiency can cause hypocalcemic seizures, growth disturbances, and rickets and may influence diabetes, cardiovascular dysfunction, autoimmune diseases, and attention deficit hyperactivity disorders. Reduced vitamin D levels in children presenting to pediatric orthopedic services are common.In the United Kingdom, recommendations on vitamin D supplementation are set by the Department of Health (DoH) and the National Institute of Health and Clinical Excellence. These state that all children aged 6 months to 5 years ought to receive 7 to 8.5 µg of vitamin D daily.We carried out a survey of 203 parents attending our pediatric and pediatric orthopedic and fracture clinics to evaluate parental awareness of the DoH recommendations on vitamin D supplementation for children and to assess the extent to which children were receiving vitamin D supplements.About 85.71% of parents were not aware of the recommendations. Only 14.29% stated that they were aware of the benefits of vitamin D for their children and just 17.73% of children were receiving vitamin D supplementation; 17 via formula milk and 18 via multivitamin formulations.Parents are generally not aware about vitamin D supplementation because of a lack of information with the high rates of reported suboptimal vitamin D levels amongst children not being addressed resulting in increased health risks to our children. Major improvements are needed in the implementation of supplementation at all points of contact between parents and health-care professionals.
