Objective: The aim of this study was to assess alcohol use problems in patients with migraine and tension-type headache. Method: We evaluated 81 patients with migraine and 62 patients with tension-type headache. The identification of alcohol consumption problems was carried out with Alcohol Use Disorders Identification Test (AUDIT). Alcohol use problem was defined as an AUDIT score of 8 or above. The headache impact was calculated with headache impact test (HIT-6). Results: The proportions of alcohol use problem among patients with migraine and tension-type headache were 5.2% and 16.1%, respectively (P=0.044). The headache impact was significantly higher with migraine than with tension-type headache (P<0.0001). There was an inverse correlation between headache impact and AUDIT (P=0.043). Conclusions: Our results suggest that migraine patients are less prone to alcohol use problems than tension-type headache patients. One of the possible reasons is that migraine is associated with greater impact than tension-type headache.

Objective The aim of this study was to identify potential visual prognostic markers in patients with idiopathic intracranial hypertension (IIH).  Methods Patients with IIH of an outpatient headache clinic in São Paulo, Brazil, were retrospectively evaluated and divided in two groups with and without the presence of permanent visual deficit attributed to IIH. Body mass index (BMI), opening CSF pressure, and the frequency of IIH related MRI abnormalities were compared between these two groups.  Results Twenty-nine patients, with 35,39±9,93 years, being twenty-eight female (96.55%) were included in the study. Reduced visual acuity attributed to IIH was registered in 16 (55.17%). According to BMI 17.4% had overweight and 82.6% were obese. Brain MRI was normal in 6 (20.69%). BMI, obesity, and the presence of MRI abnormalities were not associated with visual impairment. Initial CSF opening pressure was significantly higher in the group of patients with reduced visual acuity (40.4±13.14 x 30.5±3.41, P=0,015).  Conclusion Higher CSF opening pressure at onset was significantly associated with a higher percentage of visual impairment in patients with IIH suggesting this measure as a potential prognostic marker for patients with IIH.

Telemedicine is a modality of health care services delivery with the use of communication technologies. Its use has grown in several medicine areas. Several studies evaluated the feasibility, acceptance, efficacy, cost-effectiveness, and safety of telemedicine in the diagnosis and management of primary headache disorders. Videoconsultations were shown to be effective, convenient, and safe for primary headache disorders and migraine follow up. Some mobile health devices were show to improve adherence favoring better outcomes. Handling health data is a major concern so that international compliance standards must be adopted in all telemedicine procedures. The impact in the health system and increased access to appropriate primary headache treatments with the use of these technologies has yet to be elucidated.

The NIH Stroke Scale (NIHSS) is widely adopted in clinical practice. Despite being originally designed for research use, the NIHSS is a valued resource for communication and prognostication, and it is useful for the decision-making process regarding reperfusion therapies and prophylaxis. However, its assessment can be laborious and complex among even certified healthcare providers. In the context of increasing telemedicine use, an accurate assessment of the NIHSS may be crucial in acute stroke management We aimed to create and validate an automated tool for the NIHSS (SPOKES) in a national telemedicine service. A board of five certified vascular neurologists created an NIHSS algorithm based on a tree decision, including tips and hints in the main questions and auxiliary boxes. We randomized 22 spoke hospitals using an automated tool to invite emergency physicians not certified in the NIHSS to use or not the SPOKES. NIHSS-certified and blinded neurologists from a hub hospital performed a double-check of each item of the NIHSS. From June to August 2022, we included 144 cases from 10 spoke hospitals. Our algorithm was fully adopted in 27 cases (19%). The median of reported NIHSS was 3 [1, 5] and 3 [2, 7] points among users and non-users, p=0.38. The general difference between the reported and the double-checked score was 0 [0, 1] points – there was no difference between those who used or did not the SPOKES (p=0.12). A complete concordant score was achieved at 66.7% (n=18/27) and 45.3% (n=53/117), χ 2 =0.036, among users and non-users, respectively. In a bivariate regression analysis, the SPOKES increased the chance of complete agreement [OR 2.4, 95%CI 1-5.8, p=0.049]. There was no difference regarding discrepant scores (≥4 points), χ 2 =0.46. Among SPOKES cases, treatment with tPA was indicated in 11.1%, versus 12.7% among non-users (p=0.59). Despite the small number of included cases, our algorithm seems to be a promising tool for the NIHSS assessment in a national telemedicine service, increasing the chance of a complete agreement with certified neurologists.
