Clinical, cytogenetic and hormonal findings in a stallion with hypospadias--a case report.

This case report describes a three-year-old Friesian stallion with hypospadias. Physical examination revealed a ventrocaudal deviation of the shaft of the penis and an incomplete glans penis. The urethral opening was 4 cm in length, slit-like and had a mucous membrane covering. A short fold ran from the ventral aspect of the anus and ended with a non-pigmented hairless area of skin. A human choriongonadotropin (hCG)-stimulation test resulted in an increase in the plasma levels of estrogen sulfate and testosterone, indistinguishable from that of a normal stallion. The karyogram had a normal number of chromosomes at 2n=64. The stallion was castrated, and histological evaluation of the testicular tissue was unremarkable. In contrast to other animal species and human beings, hypospadias is a rare congenital abnormality in stallions, the cause of which could not be elucidated in our patient.

Cerebral listeriosis in an adult Freiberger gelding.

Listeria monocytogenes infection, although rare in horses, can lead to septicaemia, gastroenteritis and abortion or stillborn foals. Equine cerebral listeriosis has been reported, but only in newborn animals. This report describes a Freiberger gelding with severe neuronal symptoms of sudden onset. The animal collapsed within 24 h and was humanely killed. Necropsy revealed multiple small brown to reddish foci within the brain stem and pons. Histopathology demonstrated multifocal suppurative meningoencephalitis with microabscesses and occasional intra-lesional, coccoid to rod-shaped, bacteria. These were identified immunohistochemically as Listeria spp. and further specified as L. monocytogenes by a commercial test system based on in-situ hybridization.

[Diseases of the patella caused by clothing (author's transl)].

Fashionable clothing involving tight-fitting trousers and high heels forces human to adopt an attitude leading to diseases at the point of insertion of the tendons and of the cartilage of the patella. It is emphasized that malformations of the femoropatellar joint may possibly be caused by exogenous influences and may, therefore, be successfully treated by externally applied methods during the growth period.

[Rowing with an endoprosthesis of the hip (author's transl)].

After inserting an endoprosthesis of the hip sports activities are mandatory to restore and maintain joint function. Rowing is compared with other disciplines as a most suitable sport. It entails all the advantages which are beneficial to patients with a hip endoprosthesis and should be generally adopted as an appropriate rehabilitation measure.
