The use of NDYAG laser combined with pulsed light in the treatment of rosacea

Rosacea is a chronic inflammatory skin disease with a complex pathogenesis that mainly affects the central part of the face, with a global incidence of 5.46%. The present study was performed on a group of 68 patients with rosacea 1 and 2 subtypes, patients between 34-63 years old. The treatments were performed using a Cutera Xeo laser, using 2 types of probes: NdYag 1064nm for telangiectasias and LimeLight 520-1100nm for diffuse facial erythema, papules, and pustules, having an 10x30mm window. For patients with diffuse facial erythema, etc., the optimal number of sessions was between 3 and 6 with or without anesthetic cream, using energies between 14-19J / cm. The average recovery time was 5 days. Registered effects included bruises, pustules, burning sensation, transient stinging, and hypopigmentation. For patients with telangiectasia, the optimal number of sessions was two, performed at an average interval of once per month/ monthly

Infratentorial Cerebral Microbleeds in Patients with Cerebral Amyloid Angiopathy

International audienceBACKGROUND: Cerebral microbleeds (CMBs) observed in hypertension-related arteriolosclerosis tend to occur in the supratentorial deep gray matter, whereas those in cerebral amyloid angiopathy (CAA) typically show a supratentorial lobar distribution. Recently, superficial spontaneous cerebellar intracerebral hemorrhage has been shown to be associated with strictly lobar CMBs. Few data exist on infratentorial CMBs in CAA. The purpose of this study was to describe the incidence, number, and characteristics of infratentorial CMBs in patients with CAA. METHODS: We performed a retrospective analysis of data derived from a prospectively recruited cohort of patients with possible or probable CAA according to the Boston criteria. RESULTS: A total of 115 patients with CAA (59% with CMBs) were analyzed. Eighteen percent of all patients with CAA had at least 1 infratentorial CMB. For patients with CMBs, presence and median CMB number were as follows: brainstem, 8% and 1; deep cerebellum, 4% and 1; superficial cerebellum, 10% and 1.5. Brainstem or deep cerebellum CMB was associated with the presence of and with higher numbers of supratentorial deep gray matter CMBs (P \textless .001 for both) and with hypertension (P = .048), whereas superficial cerebellar CMB was associated with the presence of and with higher numbers of supratentorial lobar CMBs (P \textless .001 for both). CONCLUSIONS: Based on our study, superficial cerebellar CMBs (in low numbers when present) seem to be a CAA-related phenomenon observed in a minority of patients who have CAA with a relatively high supratentorial lobar CMB load

Characterizing Deep White Matter Hyperintensities in Patients with Symptomatic Isolated Cortical Superficial Siderosis

International audienceBACKGROUND:In patient with cerebral amyloid angiopathy (CAA) presenting with lobar hemorrhage (LH), magnetic resonance imaging (MRI) white matter hyperintensities (WMH) tend to be predominant in posterior regions with the "multiple subcortical spots" WMH pattern as the most frequent topographical WMH pattern. Our aim was to analyze WMH severity and topographical distribution in patients with cortical superficial siderosis (CSS).METHODS:We retrospectively analyzed MRIs from consecutive symptomatic isolated (i.e., without LH) CSS and LH-CAA (with or without associated CSS) patients. We analyzed baseline clinical characteristics including age, history of hypertension, diabetes, hypercholesterolemia, and pre-existing cognitive deficit. The presence of lobar microbleeds (MB) was scored on T2*. FLAIR (fluid-attenuated inversion recovery) WMH severity (using the Fazekas scale) and topographical distribution (using [slightly modified] earlier described WMH patterns) were analyzed and compared between both groups.RESULTS:Twenty CSS and 63 LH-CAA patients were analyzed. Baseline clinical characteristics were similar between both groups, except for hypercholesterolemia less frequently present in the CSS group (P = .026). Lobar MB were significantly less frequently present in the CSS group (P < .01), and CSS was more frequently focal in the CSS group compared with LH-CAA patients with associated CSS (P = .03). Mean Fazekas scale was significantly lower in CSS patients (P = .011). WMH patterns did not differ between both groups, with the multiple subcortical spots pattern as the most frequently observed pattern.CONCLUSIONS:Relative severe WMH scores and similar topographical distribution in CSS patients argue for WMH as a CAA-related feature in these patients with isolated CSS, adding level of evidence that isolated CSS could correspond to early manifestations of CAA

Small obliquely oriented cortical cerebellar infarctions are associated with cardioembolic stroke

International audienceBACKGROUND:A revised classification of cerebellar infarctions (CI) may uncover unrecognized associations with etiologic stroke subtypes. We hypothesized that obliquely oriented small cortical cerebellar infarction (SCCI) representing end zone infarctions on MRI would be associated with cardiac embolism.METHODS:We retrospectively analyzed consecutive stroke patients recruited between January-December 2016 in our center. Analyzed baseline characteristics: sex, age, cardiovascular risk factors, history of stroke or atrial fibrillation (AF). TOAST classification was used for determining stroke subtype. Acute infarction location (anterior/posterior/mixed anterior-posterior circulation), acute uni- or multiterritorial infarction, and acute or chronic CI/SCCI/non-SCCI were assessed by MRI, and vertebrobasilar stenosis/occlusion by vessel imaging. Pre-specified analysis was also performed in patients without known high cardioembolic risk (known AF history or acute multiterritorial infarction).RESULTS:We included 452 patients (CI in 154, isolated SCCI in 55, isolated non-SCCI in 50, and mixed SCCI/non-SCCI in 49). Both SCCI and non-SCCI were associated with AF history (SCCI, p = 0.021; non-SCCI, p = 0.004), additional acute posterior circulation infarction (p < 0.001 both CI-subtypes), multiterritorial infarctions (SCCI, p = 0.003; non-SCCI, p < 0.001) and cardioembolic more frequent than large-artery atherosclerosis origin (p < 0.001 for both CI-subtypes). SCCI was associated with older age (p < 0.001), whereas non-SCCI was associated with stroke history (p = 0.036) and vertebrobasilar stenosis/occlusion (p = 0.002). SCCI were older (p = 0.046) than non-SCCI patients, had less frequently prior stroke (p < 0.001), and more frequent cardioembolic infarction (p = 0.025). In patients without known high cardioembolic risk (n = 348), SCCI was strongly associated with subsequent cardioembolism diagnosis (OR 3.00 [CI 1.58-5.73, p < 0.001]). No such association was present in non-SCCI.CONCLUSIONS:Acute or chronic SCCI are strongly associated with a cardioembolic origin

Surgical, Dermatological and Morphopathological Considerations in the Diagnosis and Treatment of Cutaneous Lymphoproliferative Tumors, Primary CD4+

Primary cutaneous lymphomas are a heterogeneous group of T-cell (CTCL) and B-cell lymphomas (CBCL) developing in the skin and without signs of extracutaneous disease at the time of diagnosis. The term &ldquo;primary small/medium CD4+ T-cell lymphoma&rdquo; was changed to &ldquo;primary small/medium cutaneous CD4+ lymphoproliferative disorder&rdquo; due to its indolent clinical behavior and uncertain malignant potential. This paper presents a rare case of primary cutaneous lymphoma with small to medium CD4+ T-cells. A 37-year-old patient presented with a tumor in the frontal region that had occurred approximately 8&ndash;9 months earlier. The tumor had a diameter of about 8&ndash;9 mm, well demarcated macroscopically, it was round in shape, about 6&ndash;7 mm high, pink in color, firm in consistency and painless during palpation. Surgical excision of the tumor was performed with a margin of safety of 8 mm and deep to the level of the frontal muscle fascia. The histopathological examination supported the diagnosis of cutaneous lymphoproliferation with a nodular disposition in the reticular dermis and extension around the follicular epithelia and sweat glands, composed mainly of dispersed medium-large lymphocytes. Additional immunohistochemical examination was requested. Immunohistochemical examination confirmed the diagnosis of &ldquo;primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder.&rdquo; Patient monitoring was carried out through clinical dermatological controls at 3, 6, and 12 months. After one year, a cranio-cerebral MRI was performed. For the following 5 years, an annual dermatological examination accompanied by cranio-cerebral MRI, blood count, and pulmonary X-ray were recommended. Similarly to all solitary skin lesions, the prognosis is excellent in this case, the only treatment being surgical excision

Aristolochic acid I as an emerging biogenic contaminant involved in chronic kidney diseases: A comprehensive review on exposure pathways, environmental health issues and future challenges

Described in the 1950s, Balkan Endemic Nephropathy (BEN) has been recognized as a chronic kidney disease (CKD) with clinical peculiarities and multiple etiological factors. Environmental contaminants – aromatic compounds, mycotoxins and phytotoxins like aristolochic acids (AAs) – polluting food and drinking water sources, were incriminated in BEN, due to their nephrotoxic and carcinogenic properties. The implication of AAs in BEN etiology is currently a highly debated topic due to the fact that they are found within the Aristolochiaceae plants family, used around the globe as traditional medicine and they were also incriminated in Aristolochic Acid Nephropathy (AAN). Exposure pathways have been investigated, but it is unclear to what extent AAs are acting alone or in synergy with other cofactors (environmental, genetics) in triggering kidney damage. Experimental studies strengthen the hypothesis that AAI, the most studied compound in the AAs class, is a significant environmental contaminant and a most important causative factor of BEN. The aim of this review is to compile information about the natural exposure pathways to AAI, via traditional medicinal plants, soil, crop plants, water, food, air. Data that either supports or contradicts the AAI theory concerning BEN etiology was consolidated and available solutions to reduce human exposure were discussed. Because AAI is a phytotoxin with physicochemical properties that allow its transportation in environmental matrices from different types of areas (endemic, nonendemic), and induce CKDs (BEN, AAN) and urinary cancers through bioaccumulation, this review aims to shed a new light on this compound as a biogenic emerging pollutant.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
