question:
Question: Does clinical examination assist in the detection of systemic relapse of testicular germ cell tumour?
Answer: We suggest that, for patients following a planned programme of appointments and investigations, physical examination rarely contributes to the detection of systemic relapse in the follow-up of testicular germ cell tumours. It may therefore be possible to reconfigure follow-up to focus on investigations and telephone contact. We estimate that this change might be appropriate for 40% of attendances and might be welcomed by patients, many of whom find follow-up burdensome. If such a change were considered, patient education would be essential to ensure continuing compliance with the follow-up protocol.
answer:
no

question:
Question: Does lithium increase nitric oxide levels in subjects with bipolar disorder during depressive episodes?
Answer: The present findings suggest that lithium upregulates NO signaling in unmedicated BD with short illness duration. Further studies with larger samples are needed to confirm the effects of lithium on NO pathway and its association with synaptic plasticity and therapeutics of BD.
answer:

yes
