Death of a 23-year-old man from cardiac conduction system injury through a blunt chest impact after a car accident.
2014
Abstract Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent causes of cardiac contusion resulting from a direct blow to the chest. Myocardial contusion is difficult to diagnose; the clinical presentation varies greatly, ranging from a lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. The authors report a case of death due to a cardiac conduction system injury from a blunt chest impact following a car accident. The autopsy showed no external signs of thoracic trauma, no evident rib or sternum fractures. A small sub-endoc…
Work-Related Stress, Physio-Pathological Mechanisms, and the Influence of Environmental Genetic Factors
2019
Work-related stress is a growing health problem in modern society. The stress response is characterized by numerous neurochemicals, neuroendocrine and immune modifications that involve various neurological systems and circuits, and regulation of the gene expression of the different receptors. In this regard, a lot of research has focused the attention on the role played by the environment in influencing gene expression, which in turn can control the stress response. In particular, genetic factors can moderate the sensitivities of specific types of neural cells or circuits mediating the imprinting of the environment on different biological systems. In this current review, we wish to analyze …
ASSOCIATION BETWEEN HELYCOBACTER PYOLRI INFECTION AND PATHOLOGICAL ORAL MANIFESTATIONS
2016
DATA FROM LITERATURE ARE CONTROVERSAL REGARDING THE PRESENCE OF bELICOBACTER PYLORI (HP) IN DENTAL PLAQUE AND ITS ASSOCIATION WITH GASTRIC INFECTION. oNE OF THE POSSIBLE MECHANISMS SUGGETSED FOR RE-INFECTION IS THE RECOLONIZATION WITH HP DENTAL PLAQUE. THE PURPOSE OF THIS REVIEW WAS TO DETERMINE WHETHER DENTAL PLAQUE, POOR ORAL HYGIENE, AND PERIODONTAL DISEASE WERE RISK FACTORS FOR HP INFECTION.
Achalasie im Kindesalter: Eine separate Entität?
2007
Background Achalasia in childhood is rare, also the etiology and the pathogenesis of the early onset ort he disease is practically unknown. Little is known about the neuropathological changes in structure of the esophageal wall in non-hereditary, sporadic achalasia in children and ist differentiation to that in adults. The aim of our study was to examine the morphological properties or high-pressure zone of the lower esophageal sphincter in children who had undergone a Heller myotomy because of achalasia as well as to compare them with the pathological findings in adults. Methods Muscle biopsies of the smooth musculature, a 20 x 10 mm long segment of the myenteric of the distal esophagus (l…
La collezione di Anatomia Patologica dell'Università di Palermo: storia e consistenza al 1859.
2012
This paper outlines the history of the Cabinet of Pathological Anathomy at the University of Palermo, describes rapidly its current status and analyzes the composition of its displays in 1859. It aims to highlight the analogies with other collections of a similar kind and to pinpoint potential actions to endorse and develop this important scientific asset.

“Ehrlich färbt am längsten”. Sichtbarmachung bei Paul Ehrlich
2013
"Staining is the Best Policy". Visualization in the work of Paul Ehrlich. For nearly all of his life, the biomedical scientist Paul Ehrlich dedicated himself to work on dyes and staining at the interface between so-called color-chemistry and histopathology. The article begins by sketching out the field of histopathology at the junction of pathological anatomy, microtechniques, and the development of chemical dyes in the early 1870s when Ehrlich began his training as a medical student. The article explores Ehrlich's work staining first tissue and blood, and then pathogens and vital staining in the 1880s. In the late 1880s and 1890s, Ehrlich experimented with dyes as therapeutic agents. Stain…
Lateralized periodic discharges in insular status epilepticus: A case report of a periodic EEG pattern associated with ictal manifestation
2019
Highlights • Focal status epilepticus has to be considered in the differential diagnosis of patients presenting with aphasia, even in the absence of previous history of epilepsy. • Aphasia can be a rare presenting sign of insular lobe epilepsy. • Lateralized periodic discharges could represent an EEG ictal pattern.
MR Thermometry Data Correlate with Pathological Response for Soft Tissue Sarcoma of the Lower Extremity in a Single Center Analysis of Prospectively …
2020
Background: There is a strong biologic rationale for using locoregional hyperthermia in soft tissue sarcoma and a randomized trial reported significant improvements with hyperthermia. The aim of this study was to describe the opportunities of magnetic resonance (MR)-based thermometry in a cohort of soft tissue sarcoma patients undergoing combined radiotherapy and locoregional hyperthermia. Patients and Methods: For eleven evaluable patients, tumor volume (VTu) and a separate volume for temperature analysis with reliable temperature distribution (Vtherm) were contoured for every hyperthermia treatment (103 therapies). Temperature data were recorded for all tumors and were correlated with cli…
Biosynthesis of Lipopolysaccharide-Binding Protein in Rabbit Hepatocytes
1990
Studies reported here show that the recently discovered acute-phase protein, lipopolysaccharide-binding protein (LBP), is synthesized by hepatocytes. For these studies, explanted rabbit hepatocytes were grown in the presence of 35S-methionine. Biosynthetically labelled LBP in the cells and supernatant was identified using immunoprecipitation with rat anti-rabbit LBP antibody. This antibody immunoprecipitates both the LBP polypeptide and the glycosylated protein. With a cell-free translation system a comparison of RNA from normal rabbit liver with that isolated from acute-phase rabbit liver indicated that a translatable LBP message is only found in the RNA from acute-phase liver. Studies wit…
