Hypersensitivity reactions to non-steroidal anti-inflammatory drugs (NSAIDs) - a retrospective study.

BACKGROUND: The aim of this study was to verify the validity of clinical history and oral provocation challenges of patients with NSAID hypersensitivity and to identify safe alternatives. The COX-2 inhibitor etoricoxib, in particular, was studied. PATIENTS AND METHODS: In all, 104 patients with confirmed diagnoses of NSAID hypersensitivity treated at the Department of Dermatology, Frankfurt University Hospital, Germany between 2004 and 2012 were retrospectively studied. RESULTS: The medical history and hypersensitivity symptoms during oral provocation testing (OPT) largely coincided and were mostly mild to moderate. Acetylsalicylic acid (ASA) was the most frequent trigger both anamnestically (27.9 %) and during OPT (47.8 %). Etoricoxib caused the fewest reactions during OPT (4.2 %). Acetaminophen led to reactions in only 6.7 % of the cases studied although it was named more often in clinical histories (14 %). CONCLUSIONS: OPT should be the aim whenever possible as most symptoms are mild to moderate. To distinguish between selective and cross-hypersensitivity reactions, ASA should be part of the test protocol. Furthermore, the findings of this study indicate that etoricoxib and acetaminophen are safe treatment alternatives in case of NSAID hypersensitivity. However, these drugs should not be administered without prior OPT in an inpatient setting, as severe symptoms can occur.

Calcipotriol/betamethasone dipropionate aerosol foam for the treatment of psoriasis vulgaris: case series and review of the literature.

An aerosol foam formulation of a once-daily, fixed-dose combination of a synthetic vitamin D3 analog/synthetic corticosteroid (calcipotriol [Cal] 50 µg/g and betamethasone dipropionate [BD] 0.5 mg/g) has recently been introduced for the topical treatment of plaque psoriasis in adults. Data from several sources - randomized controlled trials, case reports (as highlighted in this review), and real-world evidence (RWE) - underscore the considerable and rapid clinical response, effectiveness, and favorable safety and tolerability of Cal/BD aerosol foam in mild-to-moderate psoriatic patients previously treated with class 3 or 4 topical corticosteroids, in patients unsatisfied with ongoing phototherapy in combination with topical therapy and in patients with moderate-to-severe psoriasis. In addition, our case series, considered together with other RWE, highlights that Cal/BD aerosol foam is more effective and with greater levels of patient preference and acceptability than comparator preparations. Thus, Cal/BD aerosol foam offers several treatment advantages, including relief of itch, and is an appropriate first-line topical therapy for consideration in patients with psoriasis of any severity.

Continuous Intraoperative Neuromonitoring in Thyroid Surgery.

Intermittent intraoperative neuromonitoring (I-IONM) has been introduced to thyroid surgery during the past two decades. The neuromonitoring devices (hardware and software) were significantly improved with the development of the second and third device generations. Needle electrodes, which were widely used 10 years ago, are almost completely substituted by less invasive, optimized endotracheal tube electrodes that ensure signal stability. In addition, recommendations of surgical societies for the standardized application of IONM have been established and incorporated into guidelines. However, due to the already very low frequency of (permanent) recurrent laryngeal nerve (RLN) paralysis following primary thyroid resections, a significant benefit of IONM compared to the "gold standard" of visual identification of the RLN alone has not been demonstrated so far. Moreover, the idea to enable surgeons to recognize impending nerve damage during (not after) dissection cannot be implemented with I-IONM techniques. The main benefit of I-IONM, therefore, remains the possible change of resection strategy in case of a "loss of signal (LOS)" after resection of one thyroid lobe in patients with planned bilateral resection. The recent introduction of continuous neuromonitoring (C-IONM) represents a significant step forward, potentially enabling the surgeon to react before irreversible damage to the RLN occurs. Preliminary data are supporting this methodological advantage.
