[Diabetes mellitus type 1 in a goat]. / Diabetes mellitus Typ 1 bei einer Ziege.

This case report describes the clinical findings, treatment and outcome of a four-year-old goat with type I diabetes mellitus. Weight loss, polydipsia and polyuria were the main clinical signs. Urinalysis revealed glucosuria, ketonuria and aciduria. The most important haematological and biochemical findings were anaemia attributable to parasitism, hyperglycaemia and hypoinsulinaemia. The goat was treated with insulin administered subcutaneously twice daily for almost four years. The goat developed bronchopneumonia at eight years of age and was euthanased. Postmortem examination showed degeneration of insulin-producing beta-cells of the pancreas.

[Radiographic findings in 4 cows with traumatic reticuloperitonitis caused by a nonmagnetic copper wire]. / Röntgenbefunde bei 4 Kühen mit Reticuloperitonitis traumatica verursacht durch einen nicht magnetischen Kupferdraht.

The goal of this study was to describe the findings in four cows with non-magnetic reticular foreign bodies composed of copper. The cows were referred to our clinic because of reduced appetite and a marked decrease in milk production. Based on the clinical findings, a tentative diagnosis of traumatic reticuloperitonitis was made in all cows. The reticulum of all cows was then examined ultrasonographically and radiographically. In all cows, radiographs of the reticulum showed wire-shaped foreign bodies, ranging from 3 to 7 cm in length, which appeared to have penetrated the reticular wall. Two cows (No. 3, 4) had a magnet in the reticulum close to the foreign body but there was no direct contact between the two. A magnet was administered to cows No. 1 and 2, and radiography of the reticulum was performed for a second time the following day. The magnets were observed in the reticulum; however, they did not contact the foreign bodies. Because all the magnets were correctly placed in the reticulum yet, despite close proximity, did not contact the foreign bodies, the latter were thought to be non-magnetic. Cow No. 1 was slaughtered. Left flank laparoruminotomy was performed in the remaining three cows. In all cows, copper foreign bodies ranging in length from 3.0 to 7.0 cm, were found in the reticulum. They had penetrated the reticular wall and were not attached to magnets. The radiographic findings described in the present study are strongly indicative of a non-magnetic foreign body. Ruminotomy is the treatment of choice but slaughter may also be considered.

Effects of atropine, scopolamine and xylazine on the placement of an orally administered magnet in cows.

This study was carried out to determine whether the administration of atropine, scopolamine or xylazine to cows before the administration of a magnet orally would help to position it in the reticulum. The transit time of the magnet through the oesophagus was also measured. Sixty Swiss Braunvieh cows were examined by radiography and ultrasonography to locate the reticulum. They were then divided into six groups of 10. Before the administration of the magnet, a control group received 4 ml saline solution subcutaneously, one group received 0.10 mg/kg of atropine subcutaneously, a second received 0.05 mg/kg of atropine intravenously, a third received 0.15 mg/kg of scopolamine intravenously, a fourth group received 0.02 mg/kg of xylazine intravenously, and the cows in the fifth group were positioned so that their forelimbs were 30 cm lower than their hindlimbs during the administration of the magnet. The passage of the magnet through the oesophagus was timed with a stopwatch and monitored with a compass. In the control group the magnet passed through in less than 60 seconds, but in four of the cows receiving either atropine or xylazine intravenously, or having their forelimbs positioned lower than their hindlimbs, it took longer than 60 seconds. In the cows receiving atropine subcutaneously or scopolamine intravenously, it took the same time as in the control group. All the cows were radiographed one-and-a-half hours after the administration of the magnet to determine its location. In seven of the 10 cows in the control group, the magnet was located in the reticulum, but in the other three it was in the cranial dorsal blind sac of the rumen. In the other five groups the magnet was located in the reticulum of between four and seven of the 10 cows, but in the cranial dorsal sac of the rumen, the rumen or in other sites in the other cows.

[The use of avermectins in two goats with demodicosis]. / Der Einsatz von Avermectinen bei zwei Ziegen mit Demodikose.

This case report describes the treatment of demodicosis (Demodex caprae) in 2 goats. The entire body surface of both goats was scattered with lens-large nodes from which pasty secretion emptied itself during palpation. One goat was administered 0.67 mg/kg Ivermectin orally once weekly for 12 weeks, the other goat was treated with 0.5 mg/kg Eprinomectin pour-on. The treatment led to an entire healing without any scar formation or depigmentations of the skin.

Ultrasonographic evaluation of reticular motility in cows after administration of atropine, scopolamine and xylazine.

The goal of this study was to evaluate the effect of various dosages and routes of administration of atropine, scopolamine and xylazine on reticular motility in cows. Groups of five cows received atropine, scopolamine or xylazine at dosages varying from 0.01 to 0.20 mg/kg. The drugs were administered intramuscularly and intravenously; atropine was also given subcutaneously. A total of 17 trials, each using five cows, were carried out. Reticular motility was assessed for 3 min immediately prior to the administration of a drug and for 21 min after administration, and the latter period was divided into seven 3-min intervals. The motility was further assessed during 3-min periods every 10 min starting 28 min and ending 141 min after administration of a drug. During each 3-min interval, the number of reticular contractions or the occurrence of reticular atony was determined. Onset and duration of reticular atony were assessed. All three drugs inhibited reticular motility but onset varied with route of administration and dosage. As expected, the onset of reticular atony occurred most rapidly after intravenous administration of each drug, followed by intramuscular and subcutaneous administration. Reticular atony occurred 0-3.0 min after the intravenous administration of each drug and at all dosages except the lowest dosage of atropine. Atony lasted for 3-111 min. Reticular atony occurred 3-18 min and 9-15 min after intramuscular and subcutaneous administration, respectively. It lasted 32-108 min and 39-122 min for the intramuscular and subcutaneous routes, respectively. For each drug, higher dosages resulted in a more rapid onset and longer duration of reticular atony than did lower dosages. This study demonstrated that administration of atropine, scopolamine and xylazine results in reticular atony. Whether this has clinical relevance requires further investigation.

Urethral duplication and chromosomal translocation in a Swiss braunvieh heifer.

As it was urinating, a six-month-old Swiss braunvieh heifer produced a second stream of urine from a fistula that opened on the ventrolateral margin of the left vulval lip. A catheter was introduced into this opening and passed easily into the bladder. Urethrography showed that the fistula joined the urethra in the mid-pelvic region and that a single canal originated from the bladder. Endoscopy confirmed this finding and also revealed a duplication of the vaginal portion of the cervix, a division of the cranial vagina by a septum and a fibrous band in the region of the hymenal ring. Cytogenetic examination revealed reciprocal translocation between chromosomes 20q23 and 22q23. A diagnosis of urethra duplex, duplication of the vaginal portion of the cervix and reciprocal autosomal translocation between chromosomes 20 and 22 was made on the basis of these findings.
