    Notizen: Abstract A rare (arteriolo-)capillomedullary venous anomaly of the cerebellum was examined with CT, MRI, and angiography. Unlike the usual venous angioma, this case had such extraordinary features as: infratentorial location, involvement of the whole left cerebellum, an arteriolocapillary component and a history of progressive vomiting and chronic constipation in a 7-year-old boy. CT and MRI were consistent with an extensive vascular malformation, but the actual diagnosis was reached by angiography.

    Beschreibung / Inhaltsverzeichnis: Summary Brain-stem gliomas occur mainly in childhood and are localized in the mesencephalon, pons and medulla oblongata. Diagnosis is a domain of MRI, requiring T2, T1 and KM. CT shows hemorrhage and calcification well. The criteria are the primary site, size, tumor growth, brain-stem enlargement, delineation, intralesional structure, exophytic components and enhancement. Secondary criteria are herniation, hydrocephalus and liquorgenic seeding. In CT glioma are hypodense, in MRI hyperintense in T2 and hypointense in T1. Enhancement is seen in 25–60% and does not allow differentiation of tumor vs nontumor or gradings. Factors influencing poor outcome are high grade, a short history, cranial nerve involvement, severe brain-stem enlargement, pontine site, diffuse growth and recurrency. The 5-year-survival rate is 30% (after radiation: focal tumors 85%, diffuse 20%). Most frequent are symptoms of brain pressure, cerebellum, cranial nerves and pyramidal tract. There is no agreement on whether biopsy is necessary or not. A diagnosis of tumor is highly suggestive if classical MRI findings fit the clinical history.
    Notizen: Zusammenfassung Hirnstammgliome treten überwiegend im Kindesalter auf und sind im Mesenzephalon, Pons und der Medulla oblongata lokalisiert. Die Diagnostik ist eine Domäne der MRT und erfordert T2-, T1-Sequenzen und Kontrastmittel (KM). Die CT ist zum Nachweis von Blutungen und Verkalkungen prädestiniert. Beurteilungskriterien sind Primärsitz, Tumorgröße, Ausdehnung, Hirnstammverbreiterung, Tumorränder, Binnenstruktur, exophytische Anteile und KM-Aufnahme. Sekundäre Kriterien sind Einklemmung, Liquoraufstau und liquorgene Aussaat. Hirnstammgliome sind im CT hypodens, im MRT in T2 hyperintens, in T1 meistens hypointens. Schrankenstörungen lassen sich in 25–60% der Fälle nachweisen und erlauben keine Differenzierung von Tumor/Nichttumor oder verschiedenen Gradierungen. Diskussion: Prognostisch ungünstig sind hohe Gradierung, kurzer klinischer Verlauf, Hirnnervenbefall, ausgeprägte Hirnstammverbreiterung, pontine Lokalisation, diffuse Ausbreitung und Rezidiv. Die 5-Jahres-Überlebensrate beträgt 30%, nach Strahlentherapie bei fokalen Tumoren 85%, bei diffusen 20%. Die häufigsten Symptome sind Hirndruckzeichen, zerebelläre Ataxie, Hirnnervenbefall und Pyramidenbahnzeichen – in ca. 40% Tortikollis. Die Biopsie wird kontrovers diskutiert. Zumindest ist bei klassischem MRT-Befund und passender Klinik die Diagnose Tumor hochwahrscheinlich.

    Notizen: Summary On the prognostic value of c-erbB2-encoded protein p185 in breast cancer there are controversal opinions. With the outlook of an evaluation of the prognostic value of p185 expression in breast cancer the relationships between p185 expression and known prognosis factors were investigated. Using polyclonal antibody against p185 33% out of 163 primary breast carcinomas are p185-positive. Within the various histological types of tumors the percentage of p185 expression differs. It is suggested that p185 indicates a certain type of biological behavior and plays a role in the pathogenesis of breast cancer. Thus the determination of p185 could allow definition of biological subclasses. A statistically significant correlation between expression of p185 and the presence of lymph node metastases or tumor size can not be proved. Nevertheless p185 expression is increased in cases with more than three positive lymph nodes. Expression of p185 correlates statistically significantly positively with histological grade and epidermal growth factor receptor, and negatively with steroid receptor status. Furthermore, high-proliferating tumors are more common in p185-positive cases than in p185-negative cases. It is concluded that p185 may be associated with an increased malignancy and proliferation activity of tumors.

    Notizen: Abstract Objective To develop a scoring system for stratifying patients in intensive care units (ICUs) by risk of developing nosocomial pneumonia (NP), based on variables generally available in an ICU, and to determine the probability of a patient developing NP in the ICU. Design and setting A 2-year prospective cohort study conducted in a medical and surgical ICU. Patients 756 patients admitted to the ICU for 48 h or more were followed up until the development of NP or death or discharge from the ICU. Measurements and results 129 (17.1%) patients developed NP, 106 (14%) in the first 2 weeks. The following independent risk factors were identified by multivariate analysis: no infection on admission [relative risk (RR)=3.1, 95% confidence intervals (CI)=2.0 to 4.8]; thorax drainage (RR=2.1, 95% CI=1.2 to 3.5); administration of antacids (RR=2.1, 95% CI=1.4 to 3.1); partial pressure of oxygen (PO2)〉110 mmHg (RR=1.6, 95% CI=1.0 to 2.6); administration of coagulation factors (RR=1.8, 95% CI=1.0 to 3.2); male gender (RR=2.7, 95% CI=1.2 to 6.3); urgent surgery (RR=2.4, 95% CI=0.9 to 6.4); and neurological diseases (RR=4.2, 95% CI=1.9 to 9.4). To obtain a predictive risk index for NP, a scoring system was developed using a multivariate model. The probability of developing NP varied between 11.0% in the lowest risk group and 42.3% in the highest risk group. The patients' risk of acquiring NP was seven times higher in the highest score category (IV) than in the lowest one (I). Conclusions ICU patients can be stratified into high- and low-risk groups for NP. No infection on admission, thorax drainage, administration of antacids, and PO2〉110 mmHg were associated with a higher risk of NP during the entire 2-week period.
