    Description / Table of Contents: Zusammenfassung Es erfolgte die retrospektive Auswertung der im Zeitraum von 1991–1997 am Institut für Rechtsmedizin der Universität Hamburg durchgeführten 6962 gerichtlichen und wissenschaftlichen Obduktionen hinsichtlich erst autoptisch identifizierter gastroduodenaler Ulzera als Ursache des plötzlichen, unerwarteten Todes. Dabei fanden sich 25 Fälle (58%) mit tödlicher Blutung, 16 Fälle (37%) todesursächlicher Perforation und 2 Fälle mit einer Koinzidenz von Blutung und Perforation. Insgesamt lag die Prävalenz letaler Komplikationen gastroduodenaler Ulzera im untersuchten Sektionsgut bei 0,62%. Folgende Aspekte sind hervorzuheben: Als Ursache des plötzlichen, unerwarteten Todes betreffen gastroduodenale Ulzera vorwiegend ältere Menschen (Durchschnittsalter der Betroffenen im untersuchten Obduktionsgut 62,2 Jahre), Angehörige sozialer Randgruppen und Abhängigkeitskranke (vorrangig Alkoholabusus). Bei fehlenden oder atypischen Krankheitssymptomen kommt es nicht selten zu ärztlichen Fehleinschätzungen der vitalen Bedrohung und unzureichender medizinischer Diagnostik.
    Notes: Abstract A retrospective review of 6962 autopsies carried out at the Institute of Legal Medicine (University of Hamburg) during 1991–1997 was performed to identify previously unknown peptic ulcer disease as the cause of sudden, unexpected death. During this period 25 cases (58%) of fatal acute bleeding, 16 cases (37%) of fatal peptic ulcer perforation and 2 cases of coincident bleeding and perforation occurred. The following aspects are emphasized: as the cause of sudden, unexpected death peptic ulcer disease mainly affects elderly people (average of the afflicted in the reviewed autopsy series 62.2 y), members of social fringe groups and addicts (predominately alcoholics). In cases of absent or atypical symptoms, preceding false medical appraisal of the life-threatening severity of the disease and insufficient diagnoses can be frequently found.

    Notes: Summary In this study we examined the preoperative value of the clonidine-suppression test in 15 patients with surgically proved pheochromocytomas. The result of the clonidine-suppression test was pathological (epinephrine plus norepinephrine above 500 ng/l 3 h after clonidine) in 10 of 15 patients (66%). These patients had relatively large tumors and higher basal norepinephrine plasma levels. Out of the 5 cases without a pathological clonidine test 4 had normal basal plasma catecholamine levels with the result that the clonidine test could not be properly applied and 1 case produced a false negative result. These 5 cases generally had smaller tumors and lower plasma catecholamine levels. Two of these cases had basally raised epinephrine values. The other three cases had either a paradoxical increase or a suspiciously low fall (less than 25%) in norepinephrine within the normal range. We conclude that the clonidine-suppression test is only reliable for the diagnosis of relatively large pheochromocytomas.

    Notes: Summary In a retrospective study of 31 patients with suspected pheochromocytoma we examined the preoperative results of131I-metaiodobenzylguanidine (131-I-MIBG) scintigraphy and a fluorimetric urine catecholamine determination test. An additional radioenzymatic plasma catecholamine determination test was performed in 25 patients. In 14 of the 31 patients the diagnosis of pheochromocytoma was later histologically confirmed. In the remaining 17 patients the suspected diagnosis was finally rejected after a clinical decision had been made on the basis of clinical history, symptoms, laboratory and imaging tests. 131-I-MIBG scintigraphy apparently had a very high specificity (no false-positive results among the patients with rejected diagnosis), but showed the least sensitivity (3 of 14 tumours were not detected). Urine cate-cholamines showed two false-negative and three false-positive results. Plasma catecholamines had the highest sensitivity and gave only one false-positive result. Because of its high pathognomonic value 131-MIBG scintigraphy can be helpful not only for localization, but also for confirmation of diagnosis when catecholamine determination tests are contradictory. On the basis of our experience with false-positive results after interfering medication therapy, urine and plasma catecholamine determination tests should only be carried out after purification with thin layer chromatography or high performance liquid chromatography.

    Description / Table of Contents: Between 1992 and 1999, 20 cases of a previously undiagnosed meningitis (10 males, mean age 49.2 years; 10 females, mean age 53.4 years) out of a total of 8305 autopsies were identified, corresponding to a frequency of 0.23% in the reviewed autopsy material. In 8 cases, the deceased seeked medical advice shortly before death due to unspecific complaints. In 10 cases, a peracute course of the disease was considered retrospectively. Affected persons under 40 years of age frequently died in hospital whereas persons over 60 years of age died more often in their domestic environment. At the onset of symptoms, persons between 40 and 60 years of age complained of headaches and indisposition significantly more often than persons under 40 years or over 60 years of age. Postmortem swabs of the leptomeninx resulted in cultural growth of pathogenetic germs in 12 out of 14 cases examined (Streptococcus pneumoniae n = 8; Neisseria meningitidis (capsular type C) n = 2; Staphylococcus aureus n = 1; Streptococcus pyogenes n = 1). Most frequent concomitant diseases diagnosed at autopsy were acute tracheobronchitis, pneumonia and purulent sinusitis but in general a definitive identification of the entry site of bacteria is not possible postmortem. Histomorphologically, the predominant type was tegmental meningitis with a mixed polymorphonuclear cell infiltrate. In the forensic elucidation of fatalities due to meningitis, questions concerning medical malpractice can be raised (e. g. misdiagnosis, late diagnosis). In cases with preceding craniocerebral trauma, the forensic expert is confronted with the question of causality between trauma and death.
    Notes: Unter den im Zeitraum von 1992–1999 am Institut für Rechtsmedizin der Universität Hamburg durchgeführten 8305 gerichtlichen und wissenschaftlichen Obduktionen fanden sich 20 Fälle (männliches Geschlecht n = 10, Durchschnittsalter 49,2 Jahre; weiblich n = 10, Durchschnittsalter 53,4 Jahre) erst autoptisch diagnostizierter bakterieller Meningitiden. Dies entspricht einer Häufigkeit von 0,23% im untersuchten Sektionsgut. In 8 Fällen befanden sich die Verstorbenen kurz vor dem Tode wegen unklarer Beschwerden in ärztlicher Behandlung, in 10 Fällen konnte der Verlauf retrospektiv als perakut eingeordnet werden. Erkrankte im Alter 〈 40 Jahre verstarben weit häufiger im Krankenhaus als Erkrankte des Alters 〉 60 Jahre, die überwiegend zu Hause verstarben. Erkrankte im Alter zwischen 40 und 60 Jahren zeigten signifikant häufiger Kopfschmerzen und Unwohlsein als initiale Symptome als Erkrankte mit einem Alter von 〈 40 Jahren und 〉 60 Jahren. Ein postmortaler Erregernachweis von Abstrichen der Leptomeninx gelang in 12 von 14 diesbezüglich untersuchten Fällen (Streptococcus pneumoniae n = 8; Neisseria meningitidis, Kapseltyp C n = 2; Staphylococcus aureus n = 1; Streptococcus pyogenes n = 1). Häufigste autoptisch festgestellte Begleiterkrankungen waren eitrige Tracheobronchitis, Pneumonie und eitrige Sinusitis, wobei eine definitive Feststellung der Eintrittspforte der Erreger am Autopsiematerial in der Regel nicht möglich ist. Histomorphologisch dominierte der Typ der Haubenmeningitis mit vorwiegend gemischtzelliger Entzündungsreaktion. Bei der forensischen Beurteilung von Meningitistodesfällen kann neben der Verkennung der Erkrankung vor dem Hintergrund evtl. unzureichender ärztlicher Diagnostik insbesondere der Prognose in Abhängigkeit vom Zeitpunkt der korrekten Diagnosestellung unter straf- und zivilrechtlichen Aspekten Bedeutung zukommen. Auch wirft die Anamnese eines vorausgegangenen Schädel-Hirn-Traumas aus rechtsmedizinischer Sicht Fragen hinsichtlich des Kausalzusammenhangs auf.

    Description / Table of Contents: Abstract Asthma is a widespread disease with an increasing prevalence. In spite of improved therapeutic strategies some cases can still take a fatal course. A total of 21 cases of acute death in asthmatics were analysed ¶(12 females and 9 males, aged between ¶2 and 75 years old), whereby 18 cases happened at home (mostly at night), 1 in a hospital, 1 in a nursing-home and 1 in a prison. ¶A history of asthmatic attacks, chronic asthmatic lesions and signs of acute airway obstruction and right cardiac failure were characteristic for all cases. Forensic investigations included questions of external violence, intoxication or incorrect medical treatment.
    Notes: Zusammenfassung Dargestellt werden 21 akute Asthma-Todesfälle von 12 weiblichen und 9 männlichen Personen zwischen 2 und 75 Jahren ohne Häufung in einem bestimmten Lebensalter. Hiervon ereigneten sich 18 Fälle zu Hause (zumeist nachts), einer im Krankenhaus, ¶einer im Pflegeheim und einer in einer Haftanstalt. Die Diagnose eines (chronischen) Asthmas war regelmäßig gestellt. Forensische Fragen zielten auf einen Ausschluss von Fremdverschulden oder eines ärztlichen Behandlungsfehlers.
