The history of techniques for abdominal equine cryptorchidectomy is briefly reviewed. The technique of suprapubic paramedian laparotomy as used since 1955 at the University of Liverpool veterinary field station is described in detail and an account given of the authors' experience with the technique in nearly 200 cases. It is concluded that the approach to the abdominal cavity is easy, that the testis itself is generally readily located and removed and that controlled repair of the incision is possible. Serious post-operative complications are rare and the danger of post-operative prolapse of bowel eliminated.

Observations on a series of 38 cases (35 Doberman Pinschers and three Great Danes) of the canine wobbler syndrome are described. Radiographic examinations suggested that the primary lesion is an intervertebral instability at C6/7, but with time, secondary changes of the disc degeneration and prolapse and vertebral body malformation causing stenosis of the vertebral canal occur. Cases detected at a young age and showing only the primary lesion were treated successfully, by disc fenestration alone or by disc fenestration and intervertebral screwing. The success rate in older cases with secondary lesions was poor and in this type of case, cord decompression by dorsal laminectomy appears necessary.

In the past, total uterine prolapse in the sow has been regarded as a grave condition because manipulative reposition through the vulva and vagina is extremely difficult, if not impossible, and amputation is merely a salvage procedure with a mortality rate approaching 100 percent. Laparotomy as a means of facilitating reduction of the prolapse in the sow appears to have been overlooked although it is a standard procedure in dogs and cats. This report describes a case of uterine prolapse in a sow successfully treated by laparotomy.

Serum calcium, magnesium and phosphate values of ewes recently affected by vaginal prolapse were compared with unaffected ewes in four flocks. Subclinical hypocalcaemia was demonstrated in some affected and unaffected ewes in three flocks. Magnesium and phosphate values were normal. In two flocks the body condition of ewes recently affected by vaginal prolapse was variable and reflected the variation in condition found in the flock. In a third flock affected ewes had significantly lower body condition scores than unaffected ewes (P less than 0.001). Analysis of the fourth flock was not possible. Oestrogenic mycotoxins were not detected in any of the feed samples taken from these flocks. The following year the management, nutrition and energy, and the protein and calcium status of ewes in 12 flocks of greyface/mule ewes with a history of a regular high (greater than 3 per cent) or low (less than 1 per cent) prevalence of vaginal prolapse were compared. A high prevalence was not associated with any particular feedstuff. A high or intermediate (1 to 3 per cent) prevalence of vaginal prolapse was found in three of the four flocks managed as a single group and these three flocks were fed on an unrestricted basis. Body condition scoring and beta-hydroxybutyrate estimation confirmed that ewes in these flocks were overfed. The prevalence of vaginal prolapse in the flocks was not related to the serum albumin, calcium or urea of the ewes. Therefore subclinical hypocalcaemia was probably a consequence of vaginal prolapse rather than a cause.

Regurgitation of blood through the left atrioventricular valve owing to the rupture of one of the chordae tendineae of the valve was diagnosed in a horse with sudden-onset respiratory distress and a holosystolic cardiac murmur. Severe regurgitation was confirmed with Doppler echocardiography and prolapse of part of the valve leaflet was identified with B-mode ultrasonography. The rupture of one of the chordae tendineae of a right accessory cusp of the left atrioventricular valve was confirmed post mortem. Bronchiolitis, multifocal haemorrhages and haemorrhagic fibrous plaques were found in the pleura of the dorsocaudal segments of the lungs.

A prospective cohort study was designed to describe the patterns and to determine the factors associated with the risk of rectal prolapse in a commercial swine herd in California, USA. Thirty (1.0 per cent) of 2862 pigs prolapsed between 12 and 28 weeks of age with the peak incidence occurring in 14- to 16-week-old pigs. The overall prolapse rate was 9.1 cases per 100,000 days at risk. Prolapse rates were highest during the winter and autumn months. Other factors associated with an increased risk of prolapse were maleness (relative risk 2.3) birthweight less than 1000 g (relative risk 3.4) Yorkshire boar A (relative risk 2.8) and dams of litter number 1 (relative risk 14.9), 2 (relative risk 8.2) and 3 (relative risk 9.8). No evidence was found to support the hypothesis that diarrhoea and coughing are factors associated with a risk of prolapse.

A postal census of vaginal prolapse in sheep flocks in the Borders region of Scotland yielded 540 replies from 963 owners (56 per cent). There were 262,250 ewes in 976 flocks and 2573 vaginal prolapses were reported. Analysis of the data revealed that 390 (40 per cent) of the flocks had no vaginal prolapses and in 237 (24.3 per cent) the reported prevalence was between 0.1 per cent and 1.0 per cent. Only 63 (6.5 per cent) of flocks had a greater than 5 per cent prevalence of vaginal prolapses. The greatest number of prolapses occurred in an upland flock of greyface ewes mated with Suffolk tups with 50 cases among 700 ewes (7.1 per cent) and the highest prevalence was in an upland Scottish blackface flock of ewes bred with Suffolk tups with 15.2 per cent (35 cases among 230 ewes). There were marked breed differences; very few hill breeds were affected and most cases occurred in greyface ewes mated with Suffolk tups.

The displacement of the tubular genital tract of ewes during pregnancy, in particular of the cervix relative to the cranial pelvic brim, was studied by sequential radiography using radio-opaque markers attached surgically before tupping. In the first year, 13 two-year-old parous ewes were fed a complete pelleted diet containing either 15 or 25 per cent fibre throughout pregnancy. The distances between the markers attached to the tubulogenital tract increased and the distance between the cervix and the cranial pelvic brim increased slightly with advancing pregnancy; the diet had no effect. In the second year, only cervical displacement was studied in 11 ewes that had suffered a cervicovaginal prolapse the previous year, and in five of their female progeny. They were divided into two groups, one of which was fed a 15 per cent-fibre complete pelleted diet and the other hay ad libitum throughout pregnancy. In two ewes, one from each dietary group, the prolapse recurred less than two weeks from term; initially it was a stage 2 prolapse, where the vaginal wall fails to return to its normal position when the ewe stands, but in one ewe it became a stage 3 prolapse, with the vagina completely everted and the cervix visible. During the stage 2 prolapse there was no evidence of caudal displacement of the cervix, whereas during the progression to the stage 3 prolapse the cervix became displaced 33 cm caudally over two to three hours.
