INTRODUCTION: Giovanni Battista Morgagni is considered the Father of Pathology and contributed much to our early understanding of neuropathology. For example, he introduced the concept that diagnosis, prognosis, and treatment of disease must be based on an exact understanding of the pathologic changes in anatomic structures. Additionally, he contributed to ...

Sarcoidosis is a chronic, multisystem, granulomatous disease of unknown etiology. It manifests with a wide range of symptoms and clinical findings, including some that occur in the head and neck. Sinonasal sarcoidosis, in particular, frequently demonstrates a rather recalcitrant course and a potential for severe complications if left untreated. We ...

The underlying cause of avascular necrosis (AVN) of the femoral head is often not apparent. We report the case of a 26 year old builder with a four month history of bilateral hip pain, and a diagnosis of bilateral femoral head avascular necrosis. Fabry's disease was identified as the probable ...

Macrocephaly, enlarged head size, can be seen in a wide range of conditions including hydrocephalus and genetic syndromes. Benign familial macrocephaly may be seen in multiple generations and is not associated with neurologic concerns. When macrocephaly is seen in conjunction with abnormal white matter on neuroimaging, specific genetic leukoencephalopathies should ...

Turkey, with its population of some 75 million, has a high rate of consanguineous marriages. Because the majority of the primary immunodeficiencies (PIDs) are inherited as autosomal recessive (AR) forms, the high consanguinity rate leads to a high prevalence of PID diseases in Turkey. The first pediatric immunology division was ...

With each failure of anti-amyloid-β therapy in clinical trials, new trials are initiated with no hint of slowing down. This may be due, in part, to the fact that the amyloid cascade hypothesis has been so modified over time that it is now impossible to confirm or deny. The hypothesis ...

Both Alzheimer's disease type pathology (neuritic plaques and neurofibrillary tangles) and evidence of atherosclerosis and infarcts are common in autopsy specimens from the brains of patients enrolled in longitudinal prospective cohorts; the relative contribution of each of these to overall cognitive function is unclear. In addition whether each of these ...

ABSTRACT Alzheimer's disease is a neurodegenerative disorder characterized by progressive decline in memory, loss of professional skills, impairment of judgement and behavior, and decline in social performances. In terms of neuropathology, the morphological hallmarks of the disease are the accumulation of alpha-beta peptide and the neurofibrillary degeneration, associated with synaptic ...

The National Institute on Aging Preclinical Alzheimer's disease Workgroup (PADW) has issued a preliminary report with recommendations for classifying preclinical Alzheimer's disease (pAD) according to 3 early disease stages. Here we examine the PADW recommendations in relation to neuropathological features in a large, consecutive series of cognitively intact elderly persons, ...

Sporadic tauopathies are characterized by differential cellular and topographical predominance of phospho-tau immunoreactivity and biochemical distinction of the tau protein. Established entities include progressive supranuclear palsy, corticobasal degeneration, Pick's disease, and argyrophilic grain disease. During a community-based longitudinal study on aging, we detected tau pathologies not compatible with these categories. ...

Tau dysfunction has been associated with a host of neurodegenerative diseases called tauopathies. These diseases share, as a common pathological hallmark, the presence of intracellular aggregates of hyperphosphorylated tau in affected brain areas. Aside from tau hyperphosphorylation, little is known about the role of other posttranslational modifications in tauopathies. Recently, ...

The occurrence of a plaque-dependent inflammation in Alzheimer's disease has been extensively documented in both human specimens and transgenic models of the disease. Since insoluble plaques are present in AD patients from early preclinical stages of the pathology, the point at which neuroinflammation first occurs in the progression of the ...

Cardiovascular disease is a leading cause of death and pathologic coagulation plays an integral role in the development, propagation, and intervention of cardiovascular disease. The 2 classic anticoagulants, heparin and vitamin K antagonists, though having served humanity for nearly a century, are both inconvenient and nonspecific. Through both direct and ...

Abstract Dementia is a growing public health concern because of the lack of effective curative treatment options and a rising global prevalence. Alzheimer's disease (AD) is the most common type of dementia, affecting 60%-70% of all patients with dementia. The main pathological features of Alzheimer's dementia are neurofibrillary tangles and ...

While some infectious agents have been linked to onset of autoimmune disease there is also other evidence suggesting that certain infectious agents might inhibit autoimmune pathology. This review focuses on the ways in which infectious agents or their products might intervene in an autoimmune response.

Representing the most common cause of dementia, Alzheimer's disease (AD) has dramatically impacted the neurological and economic health of our society. AD is a debilitating neurodegenerative disease that produces marked cognitive decline. Much evidence has accumulated over the past decade to suggest soluble oligomers of beta-amyloid (Aβ) have a critical ...

Nowadays, the emerging role of amyloid-β peptide (Aβ) oligomers in Alzheimer's disease (AD) is widely accepted, putting aside the old idea that fibrils are the primary entities responsible for the onset of the disease. Besides, carrying the E4 isoform of apolipoprotein E (apoE) represents the highest risk of developing AD. ...

BACKGROUND: There have been no previous studies assessing the severity of regional atrophy, cell loss and lesion densities between the overlapping conditions of Parkinson's disease (PD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) and relating these pathologies to different clinical features. METHODS: Clinical indices and basal ganglia, brainstem, ...

Previous studies have shown tau pathology in the inferior colliculus (IC) and superior colliculus (SC) in Alzheimer's disease (AD); however, it has not been compared to other tauopathies, such as progressive supranuclear palsy (PSP), or characterized with respect to progression of tau pathology in AD. The main purpose of this ...

Transactive response DNA-binding protein of 43 kDa (TDP-43), an RNA and DNA binding protein involved in transcriptional repression, RNA splicing and RNA metabolism during the stress response, is the major component of neuronal inclusions in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with ubiquitin inclusions, now referred to as ...

Neurodegenerative diseases constitute a major public health issue due to an increasingly aged population as a consequence of generally improved medical care and demographic changes. Current drug treatment of Alzheimer's disease (AD), the most prevalent dementia, with cholinesterase inhibitors or NMDA antagonists has demonstrated very modest, symptomatic efficacy, leaving an ...

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterised by chronic bronchitis, largely irreversible remodelling of the small airways, and emphysematous destruction of the alveoli. COPD is projected to be the third leading cause of death worldwide by 2020. COPD often results from prolonged exposure to irritants such ...

Harnessing the immune system to clear protein aggregates is emerging as a promising approach to treat various neurodegenerative diseases. In Alzheimer's disease (AD), several clinical trials are ongoing using active and passive immunotherapy targeting the amyloid-β (Aβ) peptide. Limited emphasis has been put into clearing tau/tangle pathology, another major hallmark ...

The clinical and pathological overlap between amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) suggests these diseases share common underlying mechanisms, a suggestion underscored by the discovery that TDP-43 inclusions are a key pathologic feature in both ALS and FTLD. This finding, combined with the identification of TDP-43 mutations ...

Over the last century, benzene has been a well-studied chemical, with some acute and chronic exposures being directly associated with observed hematologic effects in humans and animals. Chronic heavy exposures to benzene have also been associated with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) in humans. Other disease processes ...

Abstract It is well known that exposure to various elements has a noticeable effect on human health. The effect of an element is determined by several characteristics, including its similarity to elements of biological necessity, metabolism, and degree of interaction with physiological processes. This review investigates the scientific literature of ...

Registries of occupational diseases in various European countries differ considerably in criteria for notification and recognition, statistical data provided and the legal and social security context. Therefore, figures on occupational diseases are not comparable between countries and are often regarded as not reliable even within a country. Still, registries of ...

Silicosis may be defined as the disease resulting from chronic occupational exposure to silica dust. Silica is primarily composed of quartz dust and has been classified since 2000 as a known human carcinogen by the U.S. government. Silicosis may lead to impairment of lung function resulting from fibrosis of the ...

Beryllium is a lightweight metal with unique qualities related to stiffness, corrosion resistance, and conductivity. While there are many useful applications, researchers in the 1930s and 1940s linked beryllium exposure to a progressive occupational lung disease. Acute beryllium disease is a pulmonary irritant response to high exposure levels, whereas chronic ...

Rather than a clinical diagnosis, in occupational medicine the critical point is the etiological diagnosis. The first is useful for the therapy, the latter for preventive, epidemiological, regulatory, and insurance measures. As with causality criteria which are employed in population studies, the answering of four easy questions allows a Primary ...

The present document is a consensus statement reached by a panel of experts on noninvasive methods for assessment of airway inflammation in the investigation of occupational respiratory diseases, such as occupational rhinitis, occupational asthma, and nonasthmatic eosinophilic bronchitis.

Lifestyle diseases characterize those diseases whose occurrence is primarily based on the daily habits of people and are a result of an inappropriate relationship of people with their environment. The main factors contributing to lifestyle diseases include bad food habits, physical inactivity, wrong body posture, and disturbed biological clock. A ...

We propose a Bayesian adjustment for the misclassification of a binary exposure variable in a matched case-control study. The method admits a priori knowledge about both the misclassification parameters and the exposure-disease association. The standard Dirichlet prior distribution for a multinomial model is extended to allow separation of prior assertions ...

Despite federally mandated safety standards, occupational lung disease remains one of the most common work-related injuries. Inhaled dust can result in a range of tissue injury in the lung and can lead to significant respiratory insufficiency causing death. Although silicosis and coal worker's pneumoconiosis are becoming less common, hypersensitivity pneumonitis ...
