[Self-impalement after thoracic stab wound. An unusual method of suicide in psychotic symptomatology].

A 35 year-old male was found dead within a vast collection of garbage in his parent's house with 13 stab wounds of the thorax. 6 years before death he had suffered from a severe cerebral trauma with intracranial hemorrhage, after which an organic psychosis had ensued. At autopsy besides the stab wounds measuring 1-3.5 cm in length and partly exhibiting a so-called "fish-tail" formation a piece of wood was detected, having penetrated the fourth intercostal space along the sternal border and lacerated the pericardium, right pulmonary hilum and the pleura parietalis at the paravertebral line between the eight and ninth rib. There the leading part of the tool had apparently broken and bent to the left in a nearly 90 degrees angle, thus penetrating the left pleural cavity with a slight laceration of the lower lobe of the lung. From the forensic pathologist's point of view this case of multiple stabbing and additional impalement was at least remarkable and at first sight might have raised a suspicion of homicide due to the extent of the rib penetrations and especially the intrusion of the wooden device, which had been pushed by substantial force into an already existing wound. The police presupposed a suicide based on the personal history and situation at the site, where no traces suggesting an activity of somebody else could be ascertained. Reconstruction of the case and resulting differential diagnostic considerations are to be discussed.

[Distribution of opisthorchiid liver flukes in red foxes (Vulpes vulpes) in western Brandenburg].

226 (= 43.9%) out of 515 red foxes originating from the western districts of the Federal State Brandenburg were positive for opisthorchiid flukes. Metorchis bilis, Opisthorchis felineus and Pseudamphistomum truncatum occurred in prevalences of 36.9, 8.9 and 0.2% respectively. Although low fluke burden were predominant the maximum number of each fluke species isolated was 419, 46, and 78 respectively. No clear relations were found between the liver fluke prevalence and the proportion of surface waters of the different administrative districts. However, most positive foxes originated from municipalities closely situated to rivers, canals, and lakes.

[Liver fluke infection and sarcoptic mange in red foxes in Berlin].

396 red foxes originating from the city of Berlin were examined for opisthorchiid liver flukes and clinical sarcoptic mange between January 1997 and March 1998. Out of 232 (= 58.6%) foxes positive for opisthorchiid flukes 221 animals harboured Metorchis bilis and 70 were infected with Opisthorchis felineus. Pseudamphistomum truncatum was found only in 8 foxes. M. bilis occurred as mono-infection in 154 animals. M. bilis in combination with O. felineus was found in 61 cases. Pure Opisthorchis infection as well as other fluke combinations were found in a small number of animals only. 85 (= 21.5%) foxes showed clinical sarcoptic mange. Liver fluke positive foxes showed a higher mange prevalence than uninfected animals. However, significant associations between flukes and manage were only found when comparing uninfected foxes with those having the highest worm burden. The association of liver flukes and mange could be established for adult female foxes by a significant Odds Ratio of 4.3.

[Helminth findings in indigenous raccoon dogs Nyctereutes procyonoides (Gray, 1843)].

Internal organs of 74 racoon dogs originating from the eastern districts of the Federal Land Brandenburg were subjected to a complete helminthological dissection. In addition, samples of diaphragma muscles from 46 further animals were examined for Trichinella larvae. Altogether 3 trematode- (Alaria alata, Isthmiophora melis, Metorchis bilis), 3 cestode- (Mesocestoides sp., Echinococcus multilocularis, Taenia polyacantha) and 7 nematode species (Capillaria aerophila, C. plica, Trichinella spiralis, Uncinaria stenocephala, Molineus patens, Crenosoma vulpis, Toxocara canis) could be identified. Thereby, the racoon dog has a comparable helminth spectrum as well known in red foxes. Differences in the frequency of the occurrence of helminths in both hosts can be explained by different food preferences.

[Occurrence of parasites in indigenous birds of prey and owls].

In the present paper a general overview on parasites in birds of prey and owls is given. This part is followed by a study investigating the prevalences and species of parasites in free-ranging birds of prey and owls in Berlin and Brandenburg State, Germany. Over a one year period, 84 birds of prey and owls of the following species were examined for the presence of endo- and ectoparasites: Common Buzzard (Buteo buteo) (n = 32), Kestrel (Falco tinnunculus) (n = 20), Sparrowhawk (Accipiter nisus) (n = 9), Goshawk (Accipiter gentilis) (n = 8), Black Kite (Milvus migrans) (n = 4), Peregrine Falcon (Falco peregrinus) (n = 3), Marsh Harrier (Circus aeruginosus) (n = 1), White-tailed-Sea Eagle (Haliaeetus albicilla) (n = 1), Tawny Owl (Strix aluco) (n = 4), Long-eared Owl (Asio otus) (n = 1) and Barn Owl (Tyto alba) (n = 1). In 97.6% of the cases, ectoparasites (feather mites and hippoboscid flies) were found. Especially eyasses (93.3%) were positive for hippoboscid flies. Trichomonas was detected in 28.6% of all birds of prey and owls examined. A prevalence of 100% was established in the Sparrow Hawks as well as Peregrine Falcons. Leucozytozoon sp. and Hemoproteus sp. as blood parasites were found in 26.9% of the birds in total. Common Buzzards showed the highest prevalence (44.8%). 58.3% of birds examined were positive for endoparasites. Flukes were found in 16.7%, tapeworms in 14.3%, round-worms in 48.8% and acanthocephales in 2.4% of the cases. Interestingly, Tylodelphis clavata (in a Common Buzzard) and Hovorkonema variegatum (in a Goshawk) were found for the first time in raptors. The results of this study underline the importance of a parasitological examination in the process of raptor rehabilitation.

[Results of specific hyposensitization in children with pollinosis].

Hyposensitization was carried out in 120 children aged 5 to 15 years with proven sensitivity to various pollen for 3 to 5 years before the start of the season. By reason of the results of intracutaneous tests 90 patients were treated with mixed pollen allergen and 30 patients with grass pollen allergen. A retrospective study was undertaken on the base of a questionnaire. Every year after the season duration and severity of symptoms as well as consumption of medicine were registered. The total success of hyposensitization amounted to 70.8% and this result varied on the one hand in dependence of the duration of disease on the other hand in dependence of the duration of treatment. A more inconvenient result was seen in those children who suffered from asthmatic symptoms exclusively compared to patients with hay fever. Local side effects resulted sporadically in 71.5% and systemic side effects in 15.7% by subcutaneous injection of depot-pollen allergen. Despite of extensive and not indifferent mode of treatment, hyposensitization should be performed in a correct way as soon as possible after exact indication.
