ABSTRACT
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe drug reaction that is triggered several weeks after the start of a new medication. This syndrome presents with a variety of clinical symptoms, specifically a manifestation involving a fever followed by a severe rash. A variety of medications are known to trigger DRESS, with the most common being anticonvulsants and allopurinol. Here, we discuss the case of a medication, apalutamide, that caused DRESS in our patient. Early recognition and abrupt discontinuation of the medication is required for the management of this syndrome and to minimize morbidity and mortality.
ABSTRACT
Study Objectives: Laser-assisted uvulopalatoplasty (LAUP) has been used as treatment for obstructive sleep apnea (OSA). The objective of this study was to perform a systematic review and meta-analysis for LAUP alone as treatment for OSA in adults. Methods: Three authors searched five databases (including PubMed/MEDLINE) from inception through October 30, 2016 for peer-reviewed studies, with any design/language. A study quality assessment tool was used. The PRISMA statement was followed. A meta-analysis was performed. Results: Twenty-three adult studies (717 patients) reported outcomes (age: 50 ± 9 years, body mass index: 29 ± 4 kg/m2). The pre- and post-LAUP means (M) ± standard deviations (SDs) for apnea-hypopnea index (AHI) were 28 ± 13 and 19 ± 12 events/h (32% reduction). Random effects modeling for 519 patients demonstrated an AHI mean difference (MD) of -6.56 [95% CI -10.14, -2.97] events/h. Individual patient data analyses demonstrate a 23% success rate (≥50% reduction in AHI and <20 events/h) and an 8% cure rate. Additionally, 44% of patients had worsening of their AHI after LAUP. Lowest oxygen saturation (LSAT) improved from a M ± SD of 80 ± 8% to 82 ± 7%. A limitation is that most studies were case series studies and only two were randomized controlled trials. Conclusions: In this meta-analysis, LAUP reduced AHI by 32% among all patients; while the LSAT only changed minimally. Individual data demonstrated a success rate of 23%, cure rate of 8%, and worsening of the AHI among 44% of patients. We recommend that LAUP be performed with caution or not performed at all given the unfavorable results of currently published studies.
