Purpose: To describe a case series of ocular complications associated with upper respiratory tract infections.
Methods: Four patients aged 21–61 years (three females, one male) had confirmed ocular complications connected with a general upper respiratory tract infection with myalgia and fever. Ophthalmological examination, including a visual acuity test, a slit-lamp exam, intraocular pressure measurements, fluorescein and indocyanine green angiography, optical coherence tomography (OCT), and diagnostic tests for influenza were performed in the patients (RT-PCR, HAI).
Results: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) was diagnosed in three patients and serous macular detachment (SME) in one. Influenza virus infection was confirmed by molecular biological methods (RT-PCR) or the hemagglutination inhibition test (HAI) in two patients. All patients were treated with systemic prednisone.
Conclusion: A coincidence between APMPPE and SME epitheliopathy and influenza virus infection was observed in different months of a given epidemic season. 相似文献
ObjectiveAcute food protein-induced enterocolitis syndrome (FPIES) is characterized by delayed repetitive vomiting after ingestion of a trigger food, and severe reactions may lead to dehydration, hypotension, and shock. We provide recommendations on management of FPIES emergencies in a medical facility and at home.Data SourcesThis review summarizes the literature on clinical context, pathophysiology, presentation, and treatment of FPIES emergencies.Study SelectionsWe referred to the 2017 International Consensus Guidelines for the Diagnosis and Management of FPIES and performed a literature search identifying relevant recent primary articles and review articles on clinical management.ResultsManagement of FPIES emergencies in a medical facility is based on severity of symptoms and involves rehydration, ondansetron, and corticosteroids. A proactive approach for reactions occurring at home involves prescribing oral ondansetron and providing an individualized treatment plan based on the evolution of symptoms and severity of past reactions. A better understanding of the pathophysiology of FPIES and randomized trials on ondansedron and cocorticosteroid use could lead to more targeted treatments.ConclusionChildren with FPIES are at risk for severe symptoms constituting a medical emergency. Management of FPIES emergencies is largely supportive, with treatment tailored to the symptoms, severity of the patient’s condition, location of reaction, and reaction history. 相似文献

Recent frameworks in cognitive neuroscience and behavioral neurology underscore interoceptive priors as core modulators of negative emotions. However, the field lacks experimental designs manipulating the priming of emotions via interoception and exploring their multimodal signatures in neurodegenerative models. Here, we designed a novel task that involves interoceptive and control-exteroceptive priming conditions followed by post-interoception and post-exteroception facial emotion recognition (FER). We recruited 114 participants, including healthy controls (HCs) as well as patients with behavioral variant frontotemporal dementia (bvFTD), Parkinson''s disease (PD), and Alzheimer''s disease (AD). We measured online EEG modulations of the heart-evoked potential (HEP), and associations with both brain structural and resting-state functional connectivity patterns. Behaviorally, post-interoception negative FER was enhanced in HCs but selectively disrupted in bvFTD and PD, with AD presenting generalized disruptions across emotion types. Only bvFTD presented impaired interoceptive accuracy. Increased HEP modulations during post-interoception negative FER was observed in HCs and AD, but not in bvFTD or PD patients. Across all groups, post-interoception negative FER correlated with the volume of the insula and the ACC. Also, negative FER was associated with functional connectivity along the (a) salience network in the post-interoception condition, and along the (b) executive network in the post-exteroception condition. These patterns were selectively disrupted in bvFTD (a) and PD (b), respectively. Our approach underscores the multidimensional impact of interoception on emotion, while revealing a specific pathophysiological marker of bvFTD. These findings inform a promising theoretical and clinical agenda in the fields of nteroception, emotion, allostasis, and neurodegeneration.SIGNIFICANCE STATEMENT We examined whether and how emotions are primed by interoceptive states combining multimodal measures in healthy controls and neurodegenerative models. In controls, negative emotion recognition and ongoing HEP modulations were increased after interoception. These patterns were selectively disrupted in patients with atrophy across key interoceptive-emotional regions (e.g., the insula and the cingulate in frontotemporal dementia, frontostriatal networks in Parkinson''s disease), whereas persons with Alzheimer''s disease presented generalized emotional processing abnormalities with preserved interoceptive mechanisms. The integration of both domains was associated with the volume and connectivity (salience network) of canonical interoceptive-emotional hubs, critically involving the insula and the anterior cingulate. Our study reveals multimodal markers of interoceptive-emotional priming, laying the groundwork for new agendas in cognitive neuroscience and behavioral neurology. 相似文献
The modification of wood and its treatment with various preservatives may affect its mechanical properties, hence the knowledge of the character changes in wood caused by impregnation is of great importance. Therefore, the aim of the research was to determine the effect of impregnation, with the propolis-silane preparation (EEP-MPTMOS/TEOS) consisting of the propolis extract (EEP) and silicon compounds: 3-(trimethoxysilyl)propyl methacrylate (MPTMOS) and tetraethoxysilane (TEOS), on the bending strength of treated wood. Moreover, in the study wood treated with components of the propolis-silane formulation was used, namely 70% ethanol, the propolis extract, and silanes (MPTMOS/TEOS). In order to determine whether the impregnation of wood affects its long-term bending, creep tests were performed depending on the humidity. The impregnation of wood with the propolis extract and the propolis-silane preparation (EEP-MPTMOS/TEOS) contributed to the increase in modulus of rapture and work to maximum load values compared to the untreated wood. In dry wood condition, the wood treated with EEP and EEP-MPTMOS/TEOS was characterized by lower modulus of elasticity values than the control samples. In turn, in wet wood condition, wood treated with the propolis-silane preparation showed an increase in the MOE value. Moreover, the impregnation of wood had an influence on the wood creep process under bending loads. The treated wood was characterized by higher relative creep compliance than the untreated wood. The exception was the wood impregnated with EEP-MPTMOS/TEOS, which showed comparable relative creep compliance to the control samples. The presented results indicate that wood treated with a bio-friendly preparation based on propolis and silicon compounds can be used in various application and also in variable humidity conditions. 相似文献
The majority of ocular adnexal (OA) lymphomas (OAL) are extranodal marginal zone lymphomas (MZL). First high throughput sequencing (HTS) studies on OA-MZL showed inconsistent results and the distribution of mutations in reactive lymphoid lesions of this anatomic region has not yet been sufficiently addressed. We characterized OAL and lymphoid lesions of the OA by targeted HTS. The study included 34 OA-MZL, 11 chronic conjunctivitis, five mature small cell B-cell lymphomas spreading to the OA, five diseases with increase of IgG4+ plasma cells, three Burkitt lymphomas (BL), three diffuse large B-cell lymphomas (DLBCL), three mantle cell lymphomas, three idiopathic orbital inflammations/orbital pseudo tumors (PT), and three OA lymphoid hyperplasia. All cases were negative for Chlamydia. The mutational number was highest in BL and lowest in PT. The most commonly (and exclusively) mutated gene in OA-MZL was TNFAIP3 (10 of 34 cases). Altogether, 20 out of 34 patients harbored mutually exclusive mutations of either TNFAIP3, BCL10, MYD88, ATM, BRAF, or NFKBIE, or nonexclusive mutations of IRF8, TNFRSF14, KLHL6, and TBL1XR1, all encoding for NK-κB pathway compounds or regulators. Thirteen patients (38%) had, to a great part, mutually exclusive mutations of chromatin modifier-encoding genes: KMT2D, CREBBP, BCL7A, DNMT3A, EP300, or HIST1H1E. Only four patients harbored co-occurring mutations of genes encoding for NK-κB compounds and chromatin modifiers. Finally, PTEN, KMT2D, PRDM1, and HIST1H2BK mutations were observable in reactive lymphoid lesions too, while such instances were devoid of NF-κB compound mutations and/or mutations of acetyltransferase-encoding genes. In conclusion, 80% of OA-MZL display mutations of either NK-κB compounds or chromatin modifiers. Lymphoid lesions of the OA bearing NF-κB compound mutations and/or mutations of acetyltransferase-encoding genes highly likely represent lymphomas. 相似文献
