Legal aspects of forensic DNA analysis in Germany

1997

DNA analysis may be carried out in cases of civil law (e.g., in cases of disputed paternity) as well as of criminal law (e.g., a case of murder). This overview will concentrate on DNA analysis in the context of criminal law. DNA typing of forensic stain samples is generally carried out in laboratories of the Police and of University Institutes of Legal Medicine. The police laboratories are usually part of the State Criminal Offices (Landeskriminalamt, LKA) or of the central Federal Criminal Office (Bundeskriminalamt, BKA). Each of the sixteen German Federal States (except one) has a LKA with a department carrying out forensic stain analyses. The 25 Institutes of Legal Medicine belong to the…

Hepatocellular Hyperplasia, Plasmacytoma Formation, and Extramedullary Hematopoiesis in Interleukin (IL)-6/Soluble IL-6 Receptor Double-Transgenic Mi…

1998

Cytokines interact not only with membrane anchored receptors, but also with specific soluble receptors which circulate in the bloodstream. In general, soluble cytokine receptors such as soluble tumor necrosis factor receptor, soluble interleukin 1 receptor, and soluble interleukin 4 receptor compete with their membrane-bound counterparts for the ligands and therefore act as antagonists. In contrast, soluble receptors for cytokines of the interleukin-6 (IL-6) family complex with their ligands act agonistically. Interestingly, the complex of IL-6 and the soluble interleukin 6 receptor (sIL-6R) activates target cells that do not express the membrane-bound IL-6R and therefore cannot respond to …

M-cadherin and its sisters in development of striated muscle

1999

Cadherins are calcium-dependent, transmembrane intercellular adhesion proteins with morphoregulatory functions in the development and maintenance of tissues. In the development of striated muscle, the expression and function of mainly M-, N-, and R-cadherin has been studied so far. While these three cadherins are expressed in skeletal muscle cells, of these only N-cadherin is expressed in cardiac muscle. In this review, M-, N-, and R-cadherin are discussed as important players in the terminal differentiation and possibly also in the commitment of skeletal muscle cells. Furthermore, reports are described which evaluate the essential role of N-cadherin in the formation of heart tissue.

Nitric oxide in the pathogenesis of vascular disease

2000

Nitric oxide (NO) is synthesized by at least three distinct isoforms of NO synthase (NOS). Their substrate and cofactor requirements are very similar. All three isoforms have some implications, physiological or pathophysiological, in the cardiovascular system. The endothelial NOS III is physiologically important for vascular homeostasis, keeping the vasculature dilated, protecting the intima from platelet aggregates and leukocyte adhesion, and preventing smooth muscle proliferation. Central and peripheral neuronal NOS I may also contribute to blood pressure regulation. Vascular disease associated with hypercholesterolaemia, diabetes, and hypertension is characterized by endothelial dysfunct…

Fire in operating room: The adverse "never" event. Case report, mini-review and medico-legal considerations.

2020

Abstract The patient’s security and safety represent a topic of great importance for public health that led several healthcare organizations in many Countries to share documents to promote risk management and preventing adverse events. Surgical Fire (SF) is an infrequent adverse event generally occurring in the operating room (OR) and consisting of a fire that occurs in, on, or around a patient undergoing a medical or surgical procedure. Here a medico-legal case involving a 65-year-old woman reporting burns to the neck due to an SF during a thyroidectomy was described. A literature review was performed using Pubmed and Scopus databases, focusing on epidemiology, causes, prevention activitie…

Melanoma of the oral mucosa with cerebral metastasis: a clinical case

2005

Summary Oral melanoma (OM) is an infrequent neoplasia making up less than 1% of all melanomas, and which exhibits a much more aggressive behaviour than those found on the skin. We present a case of OM located on the hard palate, vestibular alveolar gingiva of the maxilla, and upper lip in a 75-year-old patient who developed a distant metastasis on the left parietal lobe. The advanced stage of the disease contraindicated any surgical intervention and it was decided to carry out palliative radiotherapy, but the patient died before treatment.

Iatrogenic pulmonary lesions.

2018

Treatment of patients often includes the administration of medications and sometimes radiation. While the intent is to treat an underlying condition, in some cases, adverse effects occur due to these agents. Most of these adverse effects are mild, however, some can be severe and life-threatening. Furthermore, while these effects are often reversible upon cessation of exposure, especially if the inciting agent is recognized and withdrawn early, others might be permanent or even progressing. Most common histopathologic findings in drug-induced interstitial lung disease include nonspecific interstitial pneumonia (cellular and/or fibrotic), organizing pneumonia with or without bronchiolitis, eo…

When a death apparently associated to sexual assault is instead a natural death due to idiopathic hypereosinophilic syndrome: The importance of gamma…

2017

We here report a case involving a 21-year-old female, found dead in a central square of a city in the south of Italy. Initial evidences and circumstances were suggestive of a death associated with a sexual assault. Two peripheral blood and two vitreous humor samples were collected for the purpose of gamma-hydroxybutyric acid (GHB) testing from the dead body at two different post-mortem intervals (PMIs): approximately 2 (t0) and 36 (t1) hours. The obtained results showed that, between t0 and t1, there was an increase of GHB concentrations in peripheral blood and vitreous humor of 66.3% and 8.1%, respectively. This case was the first evidence of GHB post mortem production in a dead body and n…
