    Description / Table of Contents: Zusammenfassung. Wir berichten über eine 53 jährige Patientin, bei der 22 Jahre nach Anlage eines Ileostomas wegen eines Morbus Crohn eine Stenose im distalen Colonsegment (Hartmannstumpf) zu einer mucocelenartigen Transformation und nachfolgenden Ruptur geführt hat. Über die Ruptur eines stillgelegten Colonabschnitts nach Anlage eines Ileostomas wurde bisher offenbar noch nicht berichtet.
    Notes: Abstract. We report an unusual complication in a 53-year-old woman following ileostomy for Crohn's disease 22 years previously. A stenosis of the distal colonic segment was the reason for the formation and subsequent rupture of a huge colonic mucocele. To our knowledge, this is the first report of a ruptured mucocele of colonic origin after ileostomy.

    Notes: Abstract  We report the case of a 55-year-old man who developed heparin-induced thrombocytopenia II after a vertebral fracture. Autopsy revealed segmental hepatic vein thrombosis of the right lobe with subacute congestion and an activation of hepatic stellate cells. This case shows that heparin-induced thrombocytopenia II is a possible cause of the Budd-Chiari syndrome.

    Notes: Abstract The aim of the present study was to determine whether axonal injury (AI) induces a microglial reaction within 15 days after brain trauma. In 40 selected cases of confirmed AI, the topographical relation of AI and microglial reaction was assessed using an immunohistochemical double-labeling technique for simultaneous demonstration of AI using β-amyloid precursor protein (β-APP) antibody and of microglia using CD68 antibody. Although traumatic injury was usually followed by a moderate early diffuse rise in the number of CD68-reactive cells in the white matter, increases in macrophages in areas of AI accumulation were only sporadic and did not occur until after 4 days. At survival intervals of 5–15 days a moderate microglial reaction in regions of β-APP-positive injured axons was detected, at maximum, in half of the case material. During this interval AI-associated satellitosis-like clusters or stars described by other authors after a survival time of more than 7 weeks were an isolated phenomenon. The prolonged microglial reaction as well as the reduction of β-APP-positive AI during longer survival periods supports the hypothesis that AI is not primarily chemotactically attractive and that the damage to a portion of β-APP-stained axons may be partly reversible. Most cases clearly require a prolonged interval of more than 15 days before initiation of the final scavenger reaction. For forensic purposes the increase in the number of microglial cells within the region of AI accumulation after a survival time of more than 5 days and the multiple and distinct demonstration of star-like microglial reactions within the white matter after survival times exceeding 7 weeks may provide valuable postmortem information on the timing of a traumatic event.

    Notes: Abstract Alz-50 antibody is immunoreactive with brain tissue of subjects with Alzheimer’s disease and can also be demonstrated by immunocytochemistry in neurons of vibratome-prepared brain tissue of victims of sudden infant death syndrome (SIDS). The application of a slightly modified ImmunoMax method enabled us to demonstrate Alz-50 immunoreactivity in paraffin-embedded material. The Alz-50 epitope was detected in the hippocampus region and in nuclei of the medulla oblongata at the level of the inferior olivary protuberance in three diagnostic groups: victims of SIDS (n = 10), infants dying of subacute hypoxia/ischemia with subsequent (re-)perfusion (n=9), and infants dying of acute ischemia without (re-) perfusion (n = 7). Quantitative evaluation of the hippocampal cortex and the nucleus olivaris inferior disclosed a significantly (P 〈 0.05) higher percentage of Alz-50-reactive neurons in SIDS cases than in the control groups (hippocampal cortex and nucleus olivaris; SIDS victims: median = 100%; subacute hypoxia/ischemia: median = 33.6– 81%; acute ischemia: median = 89.2–99%). Semiquantitative analysis revealed an equally pronounced preponderance of Alz-50-reactive neurons in SIDS victims versus the control groups. This greater expression in SIDS victims may be due to an ongoing hypoxia/ischemia during agony, but the present paucity of knowledge prohibits definitive elucidation. Nevertheless, the method described here appears to offer the realistic possibility of distinguishing SIDS cases from cases of sudden death in infants due to other causes, i.e., it offers for the first time a positive criterion for the diagnosis of SIDS.
