Ichthyosis is a cutaneous disorder characterized by excessive amounts of dry thickened skin surface scales. Ocular manifestations of ichthyosis include cicatricial ectropion, which may cause exposure keratoconjunctivitis and rarely corneal perforation. Topical emollients, anti-inflammatory ointments, and systemic retinoids have been used to control the disease process, while surgical correction with donor graft has been reserved for severe cases involving corneal exposure. The authors report a case of a Caucasian male with lamellar ichthyosis with severe bilateral upper and lower eyelid cicatricial ectropion and corneal ulceration requiring surgical correction...

REVIEW
Sri Rahavi Boovarahan, Gino A Kurian
Air pollution has become an environmental burden with regard to non-communicable diseases, particularly heart disease. It has been reported that air pollution can accelerate the development of heart failure and atrial fibrillation. Air pollutants encompass various particulate matters (PMs), which change the blood composition and heart rate and eventually leads to cardiac failure by triggering atherosclerotic plaque ruptures or by developing irreversible ischemia. A series of major epidemiological and observational studies have established the noxious effect of air pollutants on cardiovascular diseases (CVD), but the underlying molecular mechanisms of its susceptibility and the pathological disease events remain largely elusive and are predicted to be initiated in the cell organelle...

The pathological accumulation of various peptides is the common base of many neurodegenerative processes, likewise Alzheimer's disease (AD). AD is carachterized by amyloid deposits which may cause modification in neurotransmission, switching on inflammatory mechanisms, neuronal death and cerebral atrophy. Diagnosis in vivo is challenging as the criteria rely mainly on clinical manifestations, which become evident only in a late stage of the disease. Currently AD diagnosis can be definitively confirmed just by postmortem histopathologic examination but in vivo imaging may improve the clinician's ability to identify AD at the earliest stage...

Alzheimer's disease, one of the most common neurodegenerative diseases, is pathologically characterized by Amyloid beta containing plaques and neurofibrillary tangles. Amyloid beta (Aβ) induces neuronal apoptosis through the intracellular Ca2+ increase, subsequent hyperactivation of cyclin-dependent kinase 5 (Cdk5) and mitochondrial abnormality. Recently, Cdk5 was identified as an upstream regulator of mitochondrial fission during neuronal apoptosis, but the underlying mechanism remains unclear. Here, in vitro phosphorylation assays showed that Cdk5 could phosphorylate the recombinant Drp1 at Serine 579...

REVIEW
Armando Luis Negri
In recent years, the role of trace elements in lithogenesis has received steadily increasing attention. It is well documented that some trace elements can influence the morphology and speed of the crystallization process. Zinc has been found in significant amounts in calcium stones relative or organic stones (uric acid and cystine), probably substituting calcium in crystals because of their similarity in charge and size. High Zn levels are present in carbapatite of Randal's plaques suggesting that zinc could promote calcium phosphate deposition in the medullar interstitium...

Here, we describe a new method that allows localized proteomics of amyloid plaques and neurofibrillary tangles (NFTs), which are the two pathological hallmarks of Alzheimer's disease (AD). Amyloid plaques and NFTs are visualized using immunohistochemistry and microdissected from archived, formalin-fixed paraffin-embedded (FFPE) human tissue samples using laser-capture microdissection. The majority of human tissue specimens are FFPE; hence the use of this type of tissue is a particular advantage of this technique...

D-dimer has emerged as a biomarker of cardiovascular event risk, yet pathophysiological factors associated with plasma D-dimer levels in stable coronary artery disease (CAD) subjects are poorly understood. In 106 stable CAD subjects undergoing intravascular ultrasound with virtual histology (IVUS-VH), we measured D-dimer, lipoprotein(a) (Lp(a)), plasminogen, biomarkers reflecting oxidation-specific epitopes (OSE) such as oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB), OxPL on plasminogen (OxPL-PLG), and autoantibodies to phosphorylcholine-BSA [PC-BSA] and a malondialdehyde [MDA] mimotope...

PURPOSE OF REVIEW: Atherosclerosis has major morbidity and mortality implications globally. While it has often been considered an irreversible degenerative process, recent evidence provides compelling proof that atherosclerosis can be reversed. Plaque regression is however difficult to appraise and quantify, with competing diagnostic methods available. Given the potential of evidence synthesis to provide clinical guidance, we aimed to review recent meta-analyses on diagnostic methods for atherosclerotic plaque regression...

Choroidal melanoma is the most common primary intraocular malignancy, yet metastatic disease remains the most common malignancy of the eye. Differentiating these entities is essential as treatment, systemic associations, and prognosis vary dramatically between the two. Established diagnostic criteria are accurate for the diagnosis of uveal melanoma. Yet, metastatic disease may be misdiagnosed as a uveal melanoma in rare cases. We report a case of metastatic clear-cell renal cell carcinoma masquerading as uveal melanoma...

Psoriasis is a systemic inflammatory disease associated with numerous comorbidities and a profound impact on patients' quality of life. While its complex immune pathogenesis is still not fully delineated, current evidence supports a fundamental role of the T-helper-17 (TH-17) pathway and its related interleukin-17 (IL-17) cytokine. Thus, new antipsoriatic therapies have been developed to block this key cytokine and its downstream effects. Secukinumab is a fully humanized, monoclonal anti-IL-17A antibody, and the first in its class to be approved by the US Food and Drug Administration for the treatment of moderate to severe plaque psoriasis...

Malignant pleural effusion (MPE) appears in up to 20% of patients with non-Hodgkin's lymphoma (NHL). The present study aimed to assess the efficacy of medical thoracoscopy (MT) in the diagnosis of patients with MPE induced by NHL. Between July 2005 and June 2014, 833 patients with pleural effusions of unknown etiology underwent MT in Beijing Chaoyang Hospital (Beijing, China), where diagnostic thoracocentesis or/and blind pleural biopsy had failed to yield an answer. Demographic, radiographic, thoracoscopic, histological and immunophenotyping data of 10 NHL patients with MPE were then retrospectively analyzed...

Background: Patients with end-stage renal disease on hemodialysis have excess cardiovascular disease (CVD) burden with substantially increased CV event rates compared with the general population. Summary: Traditional interventions that, according to standard clinical guidelines, reduce CV risk such as antihypertensive therapy, diet, exercise, and statins are not similarly effective in the hemodialysis population. This raises the question of whether additional risk factors, such as enhanced inflammation and oxidative stress, may drive the increased CVD burden in hemodialysis patients...

Synaptic loss, plaques and neurofibrillary tangles are viewed as hallmarks of Alzheimer's disease (AD). This study investigated synaptic markers in neocortical Brodmann area 9 (BA9) samples from 171 subjects with and without AD at different levels of cognitive impairment. The expression levels of vesicular glutamate transporters (VGLUT1&2), glutamate uptake site (EAAT2), post-synaptic density protein of 95 kD (PSD95), vesicular GABA/glycine transporter (VIAAT), somatostatin (som), synaptophysin and choline acetyl transferase (ChAT) were evaluated...

AIMS: Hydrogen sulfide (H2S) has a protective role in the pathogenesis of atherosclerosis by multiple pathways. Sirtuin-1 (SIRT1) is a histone deacetylase, as an essential mediated longevity gene, and has an anti-atherogenic effect by regulating the acetylation of some functional proteins. Whether SIRT1 is involved in protecting H2S in atherosclerosis and its mechanism remains unclear. RESULTS: In ApoE-knockout atherosclerosis mice, treatment with an H2S donor (NaHS or GYY4137) reduced atherosclerotic plaque area, macrophage infiltration, aortic inflammation and plasma lipid level...

Chronic oral diseases are rarely studied together, especially with an emphasis on their common risk factors. This study examined the association of added sugar consumption on "chronic oral disease burden" among adolescents, with consideration of obesity and systemic inflammation pathways through structural equation modeling. A cross-sectional study was conducted of a complex random sample of adolescent students enrolled at public schools in São Luís, Brazil ( n = 405). The outcome was chronic oral disease burden, a latent variable based on the presence of probing depth ≥4 mm, bleeding on probing, caries, and clinical consequences of untreated caries...
