Atypical radiological presentation of multiple cystic brain metastases from lung cancer simulating neurocysticercosis.
2019
Brain metastases (BMs) are usually characterised by vasogenic oedema and mass effect, but cystic appearance can rarely occur, mimicking parasitosis, such as neurocysticercosis (NCC). A woman in her mid-50s was admitted for dizziness and upper left extremity paresis. Neuroimaging showed multiple cystic lesions consistent with multiple stages of NCC evolution, and empiric albendazole was started, without any clinical improvement. A whole-body CT revealed a pulmonary lesion in the right superior lobe. Pathological analysis from brain specimen demonstrated a clear cell lung carcinoma. The patient gradually worsened and died 4 months after the diagnosis. In conclusion, multiple cystic BMs are an…
Characteristics of mucocutaneous vascular malformations drawn from a decade of a multidisciplinary committee experience.
2021
Vascular malformations (VM) are congenital, benign, and relatively frequent lesions. Scant data have been published about the epidemiology, clinical presentation, and treatment of VM from a dermatologist's perspective. The substantial differences between subtypes, broad range of specialists consulted and confusing nomenclature used over previous years may hamper a correct diagnosis. The main objective of this study is to describe VM epidemiology. As a secondary endpoint we evaluate clinical characteristics, clinical-radiological correlation and treatment approaches. We carried out an observational, descriptive, retrospective study. Cases presented to the multidisciplinary committee of our h…
Parenteral nutrition improves nutritional status, autonomic symptoms and QoL in patients with TTR-FAP
2015
Background Transthyretin related familial amyloidotic polyneuropathy (TTR-FAP) is an inherited form of amyloidosis, leading to death in about 10 years in most cases for cardiac failure or wasting syndrome. Previous study showed that modified body mass index (mBMI) was related to time before death, duration of gastrointestinal disturbances, malabsorption and functional capacity. Futhermore, outcome after liver tranplantation was greater in patients with an mBMI over 600.
Stafne's bone cavity: An unusual case with involvement of the buccal and lingual mandibular plates
2014
Lingual mandibular bone defects, also known as Stafne bone cavity (SC), are unilateral asymptomatic radiolucencies, generally seen in the mandibular angle, below the inferior alveolar canal. Although panoramic radiographies normally offer enough information to make a correct diagnosis, additional studies are often required, especially in atypical cases. The present report describes an atypical presentation of a Stafne’s bone cavity in a 78 years-old male patient. In this particular case, an asymptomatic and radiolucid lesion was observed during a routine dental examination. The computed tomography (CT) showed an involvement of both lingual and buccal mandibular plates producing a tunnel-lik…
An unusual presentation of breast tuberculosis: A case report
2020
Abstract Primary breast tuberculosis is an uncommon disease, especially in nonendemic areas. Its presentation could mimic a cancer or an abscess, but this entity must be considered for differential diagnosis in women coming from endemic countries.
Significance of I313V mutation of NLPR3 gene in two pediatric patients
2011
Results Both case #1 (M.T) and #2 (V.C) displayed a mild clinical phenotype (episodes of urticarial rash and arthralgia associated with elevation of acute phase reactants), compatible with FCAS and Muckle-Wells syndrome, respectively. Both patients displayed good response to NSAID and/or steroid on demand. Compared to HD controls, patients displayed enhanced and delayed IL1b secretion. This was accompanied by higher levels of lL1Ra and IL-6 without any significant differences in IL-8. Interestingly, parents carrying the mutation also displayed higher levels of secreted IL-1b compared to HD control group. Conclusion The I313V mutation is associated with a mild CAPS phenotype and with an incr…
Is lack of habituation a biomarker of migraine? A critical perspective
2015
Processing of sensory stimuli has been supposed to be dysfunctioning in migraine. A basis for such abnormality has been identified in a defective ability to habituate to repetitive sensorial stimulation. Habituation, i.e. the way the nervous system attenuates response to repeated non noxious stimuli is a fundamental function of sensory systems, that allows appropriate adaptation of neural responses to the relevance of incoming stimuli. In humans, habituation can be studied by evoked potentials where it is indexed by a reduction of amplitude of the evoked response to repeated stimulation. After the first evidence by Schoenen et al in 1995[1] of reduced habituation to visual evoked potentials…
Changes in glutamatergic neurotransmission within the migraine cycle
2013
Background Although some neurophysiological studies have showed cortical excitability changes during different phases of the migraine cycle, the pathophysiological mechanisms underlying attacks recurrence remain unknown. Here we evaluated the response of the migraine motor-cortex to brief trains of 5-Hz repetitive transcranial magnetic stimulation (rTMS) in order to study, indirectly, presynaptic mechanisms of glutamatergic neurotransmission across the different phases of the migraine cycle.
O046. Color vision and visual cortex excitability are impaired in episodic migraine. Simply coexisting or pathophysiologically related dysfunctions?
2015
Background and objectives Evidence of abnormal color vision processing in migraine comes from observation of positive symptoms during visual aura, effects of strong color contrast triggering attacks and of colored-spectacles reducing migraine frequency. Although the central or peripheral basis of such color misperception remains unclear, several authors reported a selective deficit of shortwavelength cones (S-cones) [1]. Sound-induced flash illusions (SIFI) are a simple way to describe visual distorsion induced by acoustic perception. SIFI critically depend on excitability of primary visual cortex (V1) as they are reduced by facilitatory anodal transcranial direct current stimulation (tDCS)…
O069. Menstrual cycle affects cortical excitability differently in females with migraine and in healthy controls: a new perspective by cross modal so…
2015
The sound-induced flash illusions (SIFI) represent a valid tool to explore multimodal perception and are critically dependent on visual and acoustic cortical excitability [1, 2]. In a previous study [3], we observed a significant reduction of illusions in migraine patients with respect to healthy controls, probably due to a condition of visual cortex hyperexcitability. Aim of the present study was to evaluate SIFI perceptions in healthy women and patients with menstrual migraine and to describe the effects of cyclical change of steroid hormones and cortical responsiveness.
