Predicting asthma-related emergency department visits using big data.

Asthma is one of the most prevalent and costly chronic conditions in the United States, which cannot be cured. However, accurate and timely surveillance data could allow for timely and targeted interventions at the community or individual level. Current national asthma disease surveillance systems can have data availability lags of up to two weeks.

Microvascular decompression of the trigeminal nerve in the treatment of SUNCT and SUNA.

Background: Medical management of short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) syndrome and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) is often unsatisfactory.

Methods: The authors report nine cases of SUNCT/SUNA that failed medical treatment and had an aberrant arterial loop either in contact with or compressing the appropriate trigeminal nerve demonstrated on MRI. All underwent microvascular decompression of the ipsilateral trigeminal nerve for intractable pain.

SUNCT and SUNA: clinical features and medical treatment.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) are considered to be rare primary headache disorders. The purpose of this study was to define the clinical features, response to prophylactic treatment and efficacy of lignocaine by subcutaneous infusion for periods of acute exacerbation requiring hospitalisation. Over a period of 6 years (March 2000--February 2006) all cases of SUNCT and SUNA in neurology clinics at the Gold Coast Hospital, Australia, were reviewed.
