Intra-epidermal electrically evoked potentials are sensitive to detect degenerative cervical myelopathy suggesting their spinothalamic propagation.

Objective: Degenerative cervical myelopathy (DCM) is a centromedullary spinal cord disorder mainly affecting crossing fibers. While contact heat evoked potentials (CHEPs) are sensitive in detecting DCM by testing spinothalamic integrity, somatosensory evoked potentials (dSSEPs) show unaffected dorsal column conduction. Intra-epidermal electrically evoked potentials (IEEPs) have unknown spinal propagation after noxious stimulation.

Synthesis of emerging cathinones and validation of a SPE GC-MS method for their simultaneous quantification in blood.

Over the past 15 years, synthetic cathinones have emerged as an important class of new psychoactive substances (NPS) worldwide. The proliferation of these psychostimulants and their sought-after effects among recreational drug users pose a serious threat to public health and enormous challenges to forensic laboratories. For forensic institutions, it is essential to be one step ahead of covert laboratories, foreseeing the structural changes possible to introduce in the core skeleton of cathinones while maintaining their stimulating activity.

Intra-epidermal evoked potentials: A promising tool for spinal disorders?

Objectives: To test the robustness and signal-to-noise ratio of pain-related evoked potentials following intra-epidermal electrical stimulation (IES) compared to contact heat stimulation in healthy controls, and to explore the feasibility and potential added value of IES in the diagnosis of spinal disorders.

Methods: Pain-related evoked potentials induced by IES (custom-made, non-invasive, concentric triple pin electrode with steel pins protruding 1 mm from the anode, triangularly separated by 7-10 mm respectively) and contact heat stimulation were compared in 30 healthy subjects. Stimuli were applied to four different body sites.

Synchronized eye movements predict test scores in online video education.

Experienced teachers pay close attention to their students, adjusting their teaching when students seem lost. This dynamic interaction is missing in online education. We hypothesized that attentive students follow videos similarly with their eyes.

Otogenic cerebral venous thrombosis in children: A review of 16 consecutive cases.

Objectives: Management of otogenic cerebral venous thrombosis (OCVT) is controversial. Despite the modern antibiotic era OCVT still represents a potential life-threatening condition. This study aims to report the clinical presentation and management in a series of children with OCTV.

Supraglottoplasty in children with laryngomalacia: A review and parents' appraisal.

Purpose: To assess the parents' perspective concerning the children's clinical picture before and after supraglottoplasty for the treatment of laryngomalacia (LM).

Materials And Methods: Retrospective study in 110 children diagnosed with LM followed at the Pediatric Otorhinolaryngology outpatient clinics of S. João Hospital Center, between 2008 and 2016.

Nasal Skin Necrosis: A Very Rare Manifestation of Antiphospholipid Syndrome.

Unlabelled: A 23-year-old woman, a smoker and oral oestrogen user, presented with nasal necrosis. No other symptoms or local trauma were described. Relevant laboratory findings included complement consumption, positive lupus-anticoagulant assay, increased rheumatoid factor and positive cryoglobulins.

Urgent tracheostomy: four-year experience in a tertiary hospital.

Background: Urgent airway management is one of the most important responsibilities of otolaryngologists, often requiring a multidisciplinary approach. Urgent surgical airway intervention is indicated when an acute airway obstruction occurs or there are intubation difficulties. In these situations, surgical tracheostomy becomes extremely important.

Audiometric Outcome Comparison between Titanium Prosthesis and Molded Autologous Material.

Objective: To evaluate and compare the audiometric outcomes of ossicular reconstruction with titanium prosthesis and autologous material.

Study Design: Retrospective cohort study.

Setting: Tertiary referral center.
