Advanced Movement: Automobilisation für Kopfgelenke und HWS

The author describes a concept of automobilisation of the cervical spine and suboccipital joints. The well known biomechanic peculiarities of cervical spine are transformed in a therapeutic setting to allow a form of automobilisation within a closed system of head and underlying base. The so resulting new patterns of movement – the so-called “advanced movement”– differ from those usually exercised. Slow motion moving and low strength efforts are resulting in mobilisation of important vertebral and soft tissue structures.     

The range of minimum provoking doses in hazelnut-allergic patients as determined by double-blind, placebo-controlled food challenges

BACKGROUND: The risk for allergic reactions depends on the sensitivity of individuals and the quantities of offending food ingested. The sensitivity varies among allergic individuals, as does the threshold dose of a food allergen capable of inducing an allergic reaction. OBJECTIVE: This study aimed at determining the distribution of minimum provoking doses of hazelnut in a hazelnut-allergic population. METHODS: Thirty-one patients with a history of hazelnut-related allergic symptoms, a positive skin prick test to hazelnut and/or an elevated specific IgE level, were included. Double-blind, placebo-controlled food challenges (DBPCFC) were performed with seven increasing doses of dried hazelnut (1 mg to 1 g hazelnut protein) randomly interspersed with seven placebo doses. RESULTS: Twenty-nine patients had a positive challenge. Itching of the oral cavity and/or lips was the first symptom in all cases. Additional gastrointestinal symptoms were reported in five patients and difficulty in swallowing in one patient. Lip swelling was observed in two patients, followed by generalized urticaria in one of these. Threshold doses for eliciting subjective reactions varied from a dose of 1 mg up to 100 mg hazelnut protein (equivalent to 6.4-640 mg hazelnut meal). Extrapolation of the dose-response curve showed that 50% of our hazelnut-allergic population will suffer from an allergic reaction after ingestion of 6 mg (95% CI, 2-11 mg) of hazelnut protein. Objective symptoms were observed in two patients after 1 and 1,000 mg, respectively. CONCLUSION: DBPCFCs demonstrated threshold doses in half of the hazelnut-allergic patients similar to doses previously described to be hidden in consumer products. This stresses the need for careful labelling and strategies to prevent and detect contamination of food products with hazelnut residues.     

Polyploidization and centrosome hyperamplification in inflammatory bronchi

OBJECTIVE AND DESIGN: Inflammatory and tumorous bronchi were screened in order to obtain new tumor relevant cytogenetic parameters. MATERIAL OR SUBJECTS: Bronchial cells of 32 patients were cultivated by standard cell culture procedures. METHODS: Tetraploidy and aneuploidy was determined by enumeration of chromosome 7 and 8 versus the number of centrosomes. The resulting data were correlated with histopathological data. RESULTS: Tetra- and aneuploidy of epithelial cells were detectable in 76% of tumor cell cultures, 75% of high grade inflammatory tissues and 40% of non- and low grade-inflammatory tissues. Additionally, we observed centrosome hyper-amplification and multipolar mitoses not only in the tumor but also in the early stages of inflammation. CONCLUSION: Inflammatory bronchi already show tumor-specific features and may consequently represent the preliminary genetic stage of cancer development in bronchi.     

Antiseptic Compounds Still Active Against Bacterial Strains Isolated from Surgical Wound Infections Despite Increasing Antibiotic Resistance

The in vitro activities of povidone iodine, potassium peroxymonosulfate, and dimethyldidecylammonium chloride were investigated against 379 nosocomial isolates of Staphylococcus aureus and Pseudomonas aeruginosa responsible for surgical wound infections in patients operated on between July 1995 and June 2001. Overall, the isolates were inhibited by the antiseptics at concentrations below those used routinely. In spite of increasing resistance to the various antibiotics used to treat surgical wound infections, no significant variation in the susceptibility to antiseptics was demonstrated during this 6-year study.

An R201H activating mutation of the GNAS1 (Gsalpha) gene in a corticotroph pituitary adenoma.

In the pituitary gland, activating mutations of the GNAS1 (Gsalpha) gene at Gln227 have been identified in adrenocorticotrophin secreting, growth hormone secreting, and prolactin secreting adenomas. To date, mutations at the codon encoding R201, typically underlying the McCune-Albright syndrome and isolated fibrous dysplasia of bone, have been demonstrated only in growth hormone secreting pituitary adenomas. In this study, a polymerase chain reaction amplified target sequence in exon 8 of the GNAS1 gene was sequenced, identifying the first R201 mutation seen in an isolated basophilic adenoma which generated Cushing's disease in a child. This case adds Cushing's disease to the range of human diseases caused by R201 mutations of the GNAS1 gene.     

Kardiale Manifestationen der HIV-Infektion

Zusammenfassung. Die Infektion mit dem humanen Immundefizienzvirus (HIV) betrifft nicht nur das Immunsystem des menschlichen Organismus, sondern schließt vielmehr eine Reihe weiterer Organsysteme mit ein. Es wird angenommen, dass bei 5-15% der HIV-positiven Patienten kardiale Manifestationen auftreten. Zu den häufigsten HIV-assoziierten kardialen Manifestationen gehören der Perikarderguss und die chronisch aktive, fokale oder diffuse Myokarditis. Endokardiale Manifestationen bei HIV-positiven Patienten treten in Form der infektiösen Endokarditis und der nichtbakteriellen thrombotischen Endokarditis auf. In der Regel weisen HIV-assoziierte kardiale Manifestationen einen langsam progredienten Krankheitsverlauf auf. Komplikationen sind Folge eines langfristig unentdeckten Fortschreitens der Erkrankung, aber auch schnell progredienter Verlaufsformen. Aufgrund der Vielzahl HIV-assoziierter kardialer Manifestationen und deren möglicher Komplikationen ist daher neben der Früherkennung ein effektives diagnostisches und therapeutisches Vorgehen erforderlich. Seit Einführung der Proteaseinhibitoren in den 90er Jahren und der Anwendung der hochaktiven antiretroviralen Kombinationstherapie (HAART) konnten sowohl Mortalität als auch Morbidität der HIV-Infektion deutlich gesenkt werden. Die Auswirkungen der HAART auf das kardiovaskuläre System sind bisher nur in Ansätzen bekannt. Als Nebenwirkungen wurden metabolische Veränderungen in Form von Hyperlipoproteinämie und Insulinresistenz bei einer Vielzahl HIV-positiver Patienten beobachtet. Es kann davon ausgegangen werden, dass durch den Anstieg der kardiovaskulären Risikofaktoren unter der HAART in den nächsten Jahren eine erhöhte Rate kardialer Erkrankungen bei HIV-positiven Patienten auftreten wird. In dem vorliegenden Übersichtsartikel wird ein Überblick über die häufigsten kardialen Erkrankungen bei HIV-Infektionen gegeben. Zusätzlich werden Vorschläge zu Diagnostik und Therapie unterbreitet und eine Einschätzung über Veränderungen der HIV-assoziierten kardialen Manifestationen nach Einführung der HAART vorgenommen. Abstract. The human immunodeficiency virus (HIV) does not only affect the immune system. Other organs including the cardiovascular system are influenced by the HIV as well. Most common HIV-associated cardiac manifestations are pericardial effusion and chronic active, focal or diffuse myocarditis. In addition to peri- and myocardial disease, endocardiac manifestations occur as infective endocarditis and nonbacterial thrombotic endocarditis in HIV-infected patients. Although most of the cardiac manifestations associated with HIV-infection exhibit a slow progression, rapid courses may lead to fatal complications. Early screening of HIV-infected patients will identify the potentially fatal complications of HIV disease and permit efficient treatment. The use of highly active antiretroviral therapy (HAART) significantly reduced the mortality and morbidity of HIV-infected patients. However, the impact that HAART will have on the incidence and prevalence of cardiac complications in HIV-infected patients is still unknown. It can be predicted, that the long-term viral infection and the increase of cardiovascular risk factors by HAART will probably lead to an increased prevalence of HIV-infected individuals with cardiac complications in the next decade. The present review describes the most frequent HIV-associated cardiac manifestations including diagnostic and therapeutic perspectives.
