Trigeminal Meningioma in a Patient with Tardive Dyskinesia as Only Symptom
2018
Most meningiomas are benign, encapsulated tumors (95% of the cases), generally undergoing a limited number of genetic aberrations. We present the case of a 74-year-old patient with no significant pathological history, who is admitted to the neurology ward for orofacial dyskinesias accompanied by hypoesthesia in the left hemiface, a symptomatology that had started insidiously about two months before and worsened progressively over the past 3 weeks. A cerebral MRI was performed which revealed a small mass with discrete T2 hyperintensity and T1 iso-signal compared to the gray matter located in the left pontine cistern, with a large, well-defined base at the level of the cerebral tentorium. The…
LSC Abstract – Oxidative stress in nasal epithelial cells from patients with primary ciliary dyskinesia
2016
Background: Primary ciliary dyskinesia (PCD) is a rare autosomal recessive inheritance disorder characterized by dysfunction of respiratory cilia and impaired mucociliary clearance, leading to respiratory problems appearing in childhood, decreased fertility and situs inversus in 50% of the cases. The deficient ciliary movement causes stasis of secretions in the airways leading to recurrent airway infection and chronic inflammation. Rationale and aims: Chronic inflammation has been associated to oxidative stress (OS). Moreover, evidence of increased OS in the airways of stable children with PCD has been shown (Zihlif, N. et al . Pediatr Pulmonol 2006; 41:509-14.). Therefore, we hypothesize t…
Oxidative stress in ciliated nasal epithelial cells from patients with primary ciliary dyskinesia
2016
Background: Primary ciliary dyskinesia (PCD) is a rare disorder characterized by dysfunction of respiratory cilia and impaired mucociliary clearance leading to recurrent airway infection and chronic inflammation appearing in childhood. Rationale and aims: Chronic inflammation has been associated to oxidative stress (OS). Moreover, evidence of increased OS in the airways of stable children with PCD has been shown (Zihlif, N. et al . Pediatr Pulmonol 2006; 41:509-14). We hypothesize that OS would be increased in ciliated nasal epithelial cells (CNEC) from patients with PCD. This study was aimed to assess the OS profile in CNEC isolated from children with PCD. Methods: CNEC were obtained from …
Transient mid-ventricular dyskinesia: a variant of Takotsubo syndrome
2008
Takotsubo Cardiomyopathy is characterized by a reversible systolic left ventricular apical ballooning. A new pattern of dyskinesia in the absence of angiographic evidence of coronary artery stenosis has been indicated like a variant of takotsubo cardiomiopathy: mid-ventricular akinesis with preservation of apical and basal contractilities revealed at echocardiograms and ventriculographies. We report the case of a 65 years old patient with this pattern, reverted in 4 weeks.
Limitations of nasal nitric oxide as a screening method of primary ciliary dyskinesia in childhood
2016
Introduction: Nasal nitric oxide (nNO) has been proposed as a screening tool for primary ciliary dyskinesia (PCD). However, there are no reference values by age in consensus guidelines. Objectives: 1) To analyze differences in nNO among a group of patients with PCD and healthy controls. 2) To determine the proportion of pediatric PCD patients with nNO values similar to healthy population. Methods: Determination of nNO by electrochemical system (NIOX Vario®) in patients with DCP (diagnosis confirmed by digital high speed videomicroscopy) and healthy controls (without asthma, rhinitis or atopic dermatitis), aged between 7 and 60 years. Results: 32 patients (17 children, 53.1%) and 32 controls…
