Home self-monitoring in patients with asthma using a mobile spirometry system.

BACKGROUND: Self-management is an appealing strategy for prevention of asthma exacerbations. This study aimed to evaluate the feasibility and safety of a portable spirometer for unsupervised home spirometry measurements among patients with asthma. METHODS: A multi-center, prospective, single-arm, open study recruited 86 patients with controlled or partly controlled asthma (41 women, 38.6 ± 10.4 y/o and 45 men, 36.2 ± 12.1 y/o). After a training session, patients performed daily spirometry at home with the AioCare® mobile spirometry system. Each spirometry examination was recorded and evaluated according to the ATS/ERS acceptability and repeatability criteria. The primary endpoint was defined as three or more acceptable examinations in any given seven-day period (+/- 1 day) during any of the three weeks of the study. The system allowed for online review of measurements by physicians/nurses to provide feedback to patients. RESULTS: Of 78 patients with complete data, 67 (86%) achieved the primary endpoint. Seventy-five (96%) participants used the device correctly once or more, and 10 (13%) patients succeeded every single day over the three-week follow-up. The rate of acceptable spirometry examinations differed between the sites (p = 0.013). Retraining was required in 20 of 62 (32%) eligible patients, and successful in 8 individuals (40%). Satisfaction with the AioCare® system was high, 90% of respondents perceived it as useful and user-friendly. CONCLUSIONS: Self-monitoring of asthma with a connected mobile spirometer is feasible, safe and satisfactory for patients with asthma. It remains to be established whether unsupervised home spirometry measurements may improve early diagnosis and outcomes of self-management in cases of exacerbation or loss of asthma control.

Highlights BoxThis study aimed to evaluate the ability of patients with asthma to perform high-quality daily spirometry examinations at home with using the AioCare^® mobile spirometry system. The study showed that unsupervised home spirometry is safe and feasible in patients with asthma. Most patients used the device on most days of the study, and nearly 90% of all patients achieved the primary endpoint. There were no device-related adverse events.

Progressive subacute Miller-Fisher syndrome successfully treated with plasmapheresis.

BACKGROUND: Miller-Fisher Syndrome (MFS) is a rare acute polyneuropathy composed of the clinical triad of ataxia, areflexia and ophthalmoplegia, with a monophasic, self-limited course and spontaneous improvement. CASE REPORT: The authors present a 65-year-old man with Miller-Fisher syndrome consisting of bilateral ophthalmoplegia, trigeminal and facial nerve palsy, mild ataxia and peripheral neuropathy. The disease had a progressive, subacute course within 3 months. A high titer of anti-GQ1b antibodies was detected. As a result of plasmapheresis, complete recovery was achieved. CONCLUSIONS: The presented case was atypical in its clinical course and treatment. It could support the theory of the continuity between MFS, Bickerstaff brainstem encephalitis (BBE), and Guillain-Barré syndrome (GBS).

[Rare clinical form of glioblastoma multiforme]. / Rzadkie kliniczne odmiany glejaka wielopostaciowego.

Glioblastoma multiforme (glioblastoma multiforme - GBM) is the most malignant tumor classified by WHO. It is also the most common primary CNS tumor with a very aggressive course and unfavourable prognosis, usually develops in adults, and is typically located supratentorially in the fronto-temporal region. However, the literature describes an unusual position of GBM (e.g. spinal cord, pons, pineal region), familial gliomas unconnected with the family of gliomas predisposed to the occurrence of syndromes, unusual glioma and metastatic sites, gliomas transplanted with organs. In this paper, based on the available literature, the authors discuss an unusual and rare form of glioblastoma multiforme.
