Diagnostiek En Therapie in De Dermatologie
Diagnostiek en therapie in de dermatologie Leidraad voor co-assistenten Maatschap Dermatologie St. Antonius Ziekenhuis, locatie Nieuwegein St. Antonius Ziekenhuis, locatie Utrecht Polikliniek Houten Polikliniek Vleuterweide Diagnostiek Het stellen van een dermatologische diagnose De dermatologie onderscheidt zich van de andere specialismen vanwege het feit dat het lichamelijk onderzoek voorafgaat aan de anamnese. De anamnese is vervolgens toegespitst op de bevindingen bij het lichamelijk onderzoek, en kan bestaan uit een speciële, dermatologische anamnese en/of een gerichte, interne anamnese. Het is voor het stellen van een dermatologische diagnose van het grootste belang om systematisch te werk te gaan. Dit geldt vooral voor personen met minder ervaring. Met name het systematisch beschrijven van wat je ziet, en vervolgens dit “plaatje” te verwoorden in een zogenaamde “efflorescentie” zijn bij het stellen van een diagnose onontbeerlijk. Een efflorescentie is een zichtbaar bestanddeel van een huidafwijking. Voor een overzicht van de efflorescenties zij verwezen naar pagina 3. De huidafwijking kan monomorf zijn, dat wil zeggen dat het bestaat uit slechts één efflorescentie,maar het kan ook uit enkele of vele efflorescenties zijn opgebouwd. Het is belangrijk bij iedere huidafwijking de meest kenmerkende efflorescentie of combinatie van efflorescenties te kiezen. Zij bepalen de morfologische diagnose, wat op zijn beurt weer een opstapje vormt voor de differentiële diagnose. Op pagina 4 is hiervan een overzicht weergegeven. Een goede richtlijn bij het beschrijven van een afwijking is het zogenaamde “PROVOKE”-systeem. PROVOKE is een acroniem voor: Plaats, Rangschikking, Omvang (aantal, grootte), Vorm, Omtrek (begrenzing), Kleur en Efflorescentie(s). Valkuilen bij het beschrijven kunnen zijn veranderingen die zich in de loop van de tijd met de huidafwijking hebben voorgedaan. -
Role of Brain Stimulation and the Blood–Brain Interface

Abstract: Inflammation of the central nervous system can be triggered by endogenous and exogenous stimuli such as local or systemic infection, trauma, and stroke. In addition to neurodegeneration and cell death, alterations in physiological brain functions are often associated with neuroinflammation. Robust experimental evidence has demonstrated that inflammatory cytokines affect the ability of neurons to express plasticity. It has been well-established that inflammation-associated alterations in synaptic plasticity contribute to the development of neuropsychiatric symptoms. Nevertheless, diagnostic approaches and interventional strategies to restore inflammatory deficits in synaptic plasticity are limited. Here, we review recent findings on inflammation-associated alterations in synaptic plasticity and the potential role of the blood–brain interface, i.e., the blood–brain barrier, Citation: Lenz, M.; Eichler, A.; in modulating synaptic plasticity. Based on recent findings indicating that brain stimulation promotes Vlachos, A. Monitoring and plasticity and modulates vascular function, we argue that clinically employed non-invasive brain Modulating Inflammation-Associated stimulation techniques, such as transcranial magnetic stimulation, could be used for monitoring and Alterations in Synaptic Plasticity: modulating inflammation-induced alterations in synaptic plasticity. -

Urticaria Classification and external resourcesICD-10L50.ICD- 9708DiseasesDB13606MedlinePlus000845eMedicineemerg/628 MeSHD014581Urtic aria (or hives) is a skin condition, commonly caused by an allergic reaction, that is characterized by raised red skin wheals (welts). It is also known as nettle rash or uredo. Wheals from urticaria can appear anywhere on the body, including the face, lips, tongue, throat, and ears. The wheals may vary in size from about 5 mm (0.2 inches) in diameter to the size of a dinner plate; they typically itch severely, sting, or burn, and often have a pale border. Urticaria is generally caused by direct contact with an allergenic substance, or an immune response to food or some other allergen, but can also appear for other reasons, notably emotional stress. The rash can be triggered by quite innocent events, such as mere rubbing or exposure to cold.

Urticarial disease is thought to be caused by the release of histamine and other mediators of inflammation (cytokines) from cells in the skin. -

Inflammation
Inflammation II. 1 Definitions Inflammation is defined as local reaction of vascularized living tissue to local injury, characterized by movement of fluid and leukocytes from the blood into the extravascular space. According the time frame is divided into two categories: acute and chronic. Function: • destroys, dilutes or walls off injurious agents • one of body’s non-specific defense mechanisms • begins the process of healing and repair 1.1 Acute Inflammation Rapid onset, usually short duration Microscopy • neutrophils dominate • other cellular elements are also involved (monocytes/macrophages, platelets, mast cells) • protein rich exudate, especially fibrin Associations • necrosis • pyogenic bacteria 1.2 Chronic Inflammation Usually long duration, but in some cases may be short. May follow acute inflammation or may have an insiduous onset (without an apparent prelude of acute inflammation). Microscopy • mononuclear cells dominate – lymphocytes – plasma cells (plasmocytes) – monocytes/macrophages • other cellular elements are also involved (eosinophils, neutrophils in active“ inflammation)1 ” • In granulomas are typical Langhans cells, large, multinuclear elements on the periphery of tuberculous granulomas. Nuclei are sometimes arranged in a horseshoe shape formation. Foreign body cells are similar, usually smaller, the horseshape formation of nuclei is not present. Both these elements are modified macrophages. • evidence of healing — fibroblasts, capillaries, fibrosis Associations • long term stimulation of immune system, autoimmunity • viral infections -
Protective Effects of Zinc-L-Carnosine /Vitamin E on Aspirin- Induced Gastroduodenal Injury in Dogs
PROTECTIVE EFFECTS OF ZINC-L-CARNOSINE /VITAMIN E ON ASPIRIN- INDUCED GASTRODUODENAL INJURY IN DOGS MASTER’S THESIS Presented in Partial Fulfillment of the Requirements for the Master of Science Degree in the Graduate School of the Ohio State University By Mieke Baan, DVM, MVR ***** The Ohio State University 2009 Master’s Examination Committee: Professor Robert G. Sherding, Adviser Professor Stephen P. DiBartola Associate Professore Susan E. Johnson Approved by Adviser Veterinary Clinical Sciences Graduate Program ! Copyright by Mieke Baan 2009 ABSTRACT Zinc plays a role in many biochemical functions, including DNA, RNA, and protein synthesis. The dipeptide carnosine forms a stable complex with zinc, which has a protective effect against gastric epithelial injury in-vitro and in-vivo. This randomized double-blinded placebo-controlled study investigated the protective effects of zinc-L-carnosine in combination with alpha-tocopheryl acetate (vitamin E) on the development of aspirin-induced gastrointestinal (GI) lesions in dogs. Eighteen mixed-breed dogs (mean 20.6 kg) were negative for parasites, and had normal blood work evaluations, and gastroduodenoscopic exams. On days 0 – 35, dogs were treated with 1 tablet (n=6) or 2 tablets (n=6) of 30 mg zinc-L-carnosine/ 30 IU vitamin E q12h PO, or a placebo (n=6). On days 7 – 35, all dogs were given 25 mg/kg buffered aspirin q8h PO. Endoscopy was performed on Days -1, 14, 21, and 35, and GI lesions (hemorrhages, erosions, or ulcers) were scored using a 12-point grading scale. Repeated measures ANOVA was used for statistical evaluation. The significance level was set at p ! 0.05. -

Medical Hypotheses 5: 1237-1249, 1979 THE NAEGLERIAL CAUSATION OF RHEUMATOID DISEASE AND MANY HUMAN CANCERS. A NEW CONCEPT IN MEDICINE. R. Wyburn-Mason, 2 Hillbrow, Richmond Hill, Richmond, Surrey, England. ABSTRACT Man and terrestrial animals live in an environment containing free- living amoebae on the surface soil, in pools, fresh water lakes, rivers and streams. They form cysts, which float in the air and which are continually inhaled and found in the nasopharynx and their trophozoites are present in human and animal faeces. Amoebae of the genus, Naegleria, have been demon- strated in all human tissues, both healthy and in larger numbers in those taken from cases of rheumatoid disease, in all human cancers and in the unaffected tissues of cancer patients. They can be killed in vitro by a series of different anti-amoebic substances and treatment of active cases of rheumatoid disease by any of these, either causes cessation of disease activity or a temporary exaggeration of symptoms followed by their lessening or disappearance (Herxheimer reaction), indicating the presence of an amoeba in the affected tissues as the causative organism of the inflammation in this disease in subjects genetically sensitive to the organism. Every internal organ may be involved in the inflammatory response in cases of rheumatoid disease and this also ceases with the above treatments. Many of these internal lesions are premalignant, so that infection with the organism either in sensitive subjects or with pathogenic species, appearsto be the primary cause of cancer in many cases. The presence in the body of Naegleria represents the source of the constant antigenic stimulation thought to be responsible both for rheumatoid disease and for the development of lymphomata and myelomatosis. -
