A case of cochlear-facial dehiscence revealed after bilateral cochlear implants.

The cochlear implant is an implanted auditory prosthesis that can restore severe and profound hearing loss. About 20% of patients with congenital sensorineural hearing loss have a malformation of the inner ear. These abnormalities must be investigated before a cochlear implant because they can lead to intra and postoperative complications and/or anomalies.

High-flow priapism: Highly selective embolization of a traumatic arterio-cavernosal fistula.

We report the case of a 14-year-old man who arrived at the emergency department affected by a high-flow priapism due to a traumatic left arterial-sinusoidal fistula. After clinical examination, a colour Doppler ultrasound of the penis was performed which showed a left arterial-sinusoidal fistula measuring 7×16×30mm, with high-speed and turbulent flow. The fistula was successfully treated by three highly selective endovascular embolizations and at the 20days follow-up, clinical examination resulted normal.

Neurovascular Neck-Bridging device in treatment of wide-necked splenic artery aneurysms.

We report the cases of 2 female patients, 45-year-old and 49-year-old, affected by wide-necked splenic aneurysm. We embolized the 2 lesions assisted by a new scaffolding neurovascular device, the Cascade Net, an innovative -occlusive remodeling device for temporary bridging in endovascular coil embolization of intracranial aneurysms. Visceral artery aneurysms are rare with an estimated prevalence of 2%-3% in imaging series and up to 10% in autopsy series.

Cerebral venous thrombosis: report of 2 cases of hemorrhagic venous infarction.

Cerebral venous thrombosis (CVT), a rare but potentially severe cerebrovascular disease, is defined as the thrombosis of a cortical or deep cerebral vein, or a cerebral venous sinus. This article reports 2 cases of CVT. In the first case, the patient is a 40-year-old woman with a history of 2 miscarriages, using oral contraception and presenting intense headache, cervical irradiation, and drowsiness.

Fluoroscopy guided electrode-array insertion for cochlear implantation with straight electrode-arrays: a valuable tool in most cases.

Purpose: To highlight the advantages of real time fluoroscopy guided electrode-array (EA) insertion (FGI) during cochlear implants surgery.

Methods: All surgical procedures were performed in a dedicated operating room equipped with a robotic C-arm cone beam device, allowing for intraoperative real time 2D FGI and postoperative 3D imaging. Only straight EAs were used.

CT-scan contouring technique allows for direct and reliable measurements of the cochlear duct length: implication in cochlear implantation with straight electrode-arrays.

Objectives: The advent of hybrid electro-acoustic implants requires precise positioning of the electrode-array (EA) within the cochlea. The cochlea size, that is, the length of the cochlear scala tympani, is often indirectly estimated from distance A by Escudé's method. This technique has been confirmed by anatomical studies, in a bunch of cadaveric specimens, but it is not yet widely established in the field of computed tomography (CT).

Apparent diffusion coefficient and enhancement patterns in MR imaging as markers of severe or moderate ileum inflammation in Crohn's disease.

Background And Purpose: magnetic resonance enterography has been increasingly used for the diagnosis and follow-up of Crohn's disease (CD). The purpose of the study was to compare the apparent diffusion coefficient (ADC) with wall enhancement for the differentiation of severe, moderate or no inflammation activity in the ileum.

Methods: a prospective, blinded study was conducted of 46 CD patients with a clinical Crohn's disease activity index (CDAI) ≥ 220 and a simple endoscopic score for Crohn's disease (ES-CD) ≥ 7, which yielded 58 inflamed segments with CD.

Intra-dialytic blood oxygen saturation (SO): association with dialysis hypotension (the SOGLIA Study).

Background: Intradialytic hypotension (IDH) has a dramatic impact on the main outcomes of dialysis patients. Early warning of hemodynamic worsening during dialysis would enable preventive measures to be taken. Blood oxygen saturation (SO) is used for hemodynamic monitoring in the critical care setting and may provide useful information about IDH onset.

Calcium profiling in hemodiafiltration: a new way to reduce the calcium overload risk without compromising cardiovascular stability.

Background: Low and high dialysate calcium (Ca²⁺) content may have positive and harmful effects depending on the considered pathological aspect: hemodynamic instability, cardiac arrhythmias, parathormone release, adynamic bone disease, cardio-vascular calcifications. We hypothesized that a time-profiled Ca²⁺ concentration would keep the cardiovascular advantages of high Ca²⁺ but would reduce the risk of calcium overload.

Methods: A prospective, multicenter study using a particular hemodiafiltration technique that allows the profiling of electrolytes was designed.
