RESUMO
One limitation to transradial access (TRA) is the occurrence of spasms (RAS), for which the use of prophylactic medications is recommended. Improvement in TRA material combined with the increase in operators' expertise, might mitigate this benefit. We assess the effect of preventive nitroglycerin on RAS during TRA, evaluating the role of the operator's experience. Patients received 500 µg nitroglycerin or placebo. The operator's expertise was classified as: inexperienced (I), intermediate (M), and experienced (E). 2040 patients were included. Prophylactic use of nitroglycerin did not reduce RAS (10.8% vs. 13.4% (placebo), p = 0.07). RAS incidence was 14.5% in I, 12.5% in M, and 9.7% in E (p = 0.01). In group I, nitroglycerin reduced RAS (17.4% vs. 11.1%, p = 0.04), which was not observed in other groups. Overall, nitroglycerin does not prevent RAS, which is more common among inexperienced operators. More experienced operators could abolish preventive nitroglycerin use.

INTRODUCTION AND OBJECTIVES: Vismodegib (Erivedge® ), a hedgehog pathway inhibitor, is approved to treat metastatic or locally advanced basal cell carcinoma (BCC) not suitable for surgery or radiotherapy. Our main objectives were to study the objective response rate (ORR) assessed by treating physicians and safety of vismodegib in a real-world practice setting in Argentina. MATERIAL AND METHODS: This is a prospective cohort study in real-world practice. We included consecutive adult patients treated in Argentina with locally advanced or metastatic BCC not suitable for surgery or radiotherapy. Patients were followed until the end of the study, death, or loss to follow-up, whichever occurred first. Patients received 150 mg vismodegib PO daily. RESULT: We included in the analysis 63 patients who received treatment. Locally advanced BCC was present in 57 (90.4%) and metastatic disease in two (3.2%). ORR was observed in 46 patients (73%; 95% CI: 60.3-83.4), with partial response in 36 (57%; 95% CI: 44-69.5) and complete response in 10 (16%; 95% CI: 7.8-27.2). As to safety, 48 (76.2%) patients had at least one adverse event (AE). The most frequently observed AEs were muscular spasms in 25 (39.6%); dysgeusia in 23 (36.5%); alopecia in nine (14.2%); weight loss in seven (11.1%); and ageusia in (9.5%) patients. Serious AEs were observed in 11 (17%) patients with one episode of deep vein thrombosis and pulmonary embolism resulting in death. CONCLUSION: Our study provides additional evidence of the efficacy and tolerability of vismodegib in patients with locally advanced or metastatic BCC in a real-world practice.

UNLABELLED: Tonic tensor tympani syndrome (TTTS) is an involuntary, anxiety-based condition where the reflex threshold for tensor tympani muscle activity is reduced, causing a frequent spasm. This can trigger aural symptoms from tympanic membrane tension, middle ear ventilation alterations and trigeminal nerve irritability. TTTS is considered to cause the distinctive symptoms of acoustic shock (AS), which can develop after exposure to an unexpected loud sound perceived as highly threatening. Hyperacusis is a dominant AS symptom. Aural pain/blockage without underlying pathology has been noted in tinnitus and hyperacusis patients, without wide acknowledgment. This multiclinic study investigated the prevalence of TTTS symptoms and AS in tinnitus and hyperacusis patients. This study included consecutive patients with tinnitus and/or hyperacusis seen in multiple clinics. DATA COLLECTED: Symptoms consistent with TTTS (pain/numbness/burning in and around the ear; aural "blockage"; mild vertigo/nausea; "muffled" hearing; tympanic flutter; headache); onset or exacerbation from exposure to loud/intolerable sounds; tinnitus/hyperacusis severity. All patients were medically cleared of underlying pathology, which could cause these symptoms. 60.0% of the total sample (345 patients), 40.6% of tinnitus only patients, 81.1% of hyperacusis patients had ≥ 1 symptoms (P < 0.001). 68% of severe tinnitus patients, 91.3% of severe hyperacusis patients had ≥ 1 symptoms (P < 0.001). 19.7% (68/345) of patients in the total sample had AS. 83.8% of AS patients had hyperacusis, 41.2% of non-AS patients had hyperacusis (P < 0.001). The high prevalence of TTTS symptoms suggests they readily develop in tinnitus patients, more particularly with hyperacusis. Along with AS, they should be routinely investigated in history-taking.
