[Recurrent vaginitis and cystitis due to a vagina and cervix duplex in a bitch - a case report]. / Rezidivierende Vaginitis und Zystitis aufgrund einer Vagina und Zervix duplex bei einer Hündin ­ ein Fallbericht.

Incomplete merging of the Müllerian ducts may result in vaginal septa or even completely separate vaginal canals. It may also cause cervical malformation. In most cases, there are only rudimentary vaginal septations. Only a few reports describing completely separated vaginal canals (vagina duplex) and a cervix duplex in dogs have been published. This article reports the case of a bitch presented with recurrent vaginitis and cystitis. The symptoms always appeared following the dog's heat. The bitch had been pre-treated by a prior veterinarian as well as in a prior clinic. When presented in the clinic, a vaginal septum was suspected based on digital vaginal examination. Ultrasonographic examination and urinalysis allowed for the diagnosis of bacterial cystitis, which was subsequently treated with antibiotics. The bitch was presented again for vaginal endoscopy, transection of the vaginal septum, and ovariohysterectomy. Both vagina duplex and cervix duplex were diagnosed. Due to the extensive dimensions of the findings, the altered tissue was not resected. No more bacteria were detected in a repeated urine analysis. After spaying, the bitch showed no recurrence of symptoms of cystitis or vaginitis.

Parameters in Canines After Cesarean Sections.

This study evaluated fertility in canines after cesarean section and compared it with natural parturition. Parameters, such as the time of the next heat after the first parturition or cesarean section, the heat which was used for another breeding attempt, whether it was successful, the number of puppies that were born, and the necessity of another cesarean section were examined. The study relied on questioning patient owners at a University clinic. A Google online form was also used. Information for 261 dogs from different breed groups was included, of which 119 bitches were in the cesarean section group, and 142 were in the natural parturition group. In total, 93 ± 2.7% [LSMeans ± standard error (SE)] and 91.12 ± 3% (LSMeans ± SE) of the bitches became pregnant after cesarean section and natural parturition at the first breeding attempt. There was no significant effect on the breed group or whether the bitch had undergone a cesarean section before (p = 0.8 and p = 0.63). Bitches, which underwent a cesarean section, were more likely to have further cesarean sections performed (p < 0.001). However, neither the breed groups (p = 0.17), whether the bitch had undergone a cesarean section (p = 0.59), nor the number of previous parities had any effect on the number of puppies born (p = 0.95). The breed group bulldogs had a high proportion of cesarean sections. Only 42.11% of the bulldogs had a natural parturition as the first included parturition and only 31% gave birth naturally thereafter.

Comparison of three progesterone quantification methods using blood samples drawn from bitches during the periovulatory phase.

Background and Aim: Measuring blood progesterone (P4) concentration has become an essential diagnostic tool in small animal reproductive medicine. Methods enabling precise and rapid on-site measurements are in high demand, especially for the optimization of breeding management in bitches. This study aimed to compare two commercial on-site methods (Speed™ P4, Virbac [M1] and mini VIDAS®, bioMérieux [M2]) and a well-established radioimmunoassay (RIA), which was used as a reference method. Materials and Methods: Comparative measurements were performed on 52 blood serum samples collected from 45 clinically healthy bitches of different breeds. The dogs had been presented to determine the estrus cycle stage and predict the time of ovulation. Each sample was divided into three aliquots. In aliquot 1, P4 was measured immediately applying M2. Aliquots 2 and 3 were stored at -20°C until analysis was performed using RIA and M1. The consistency of the three methods was investigated by pairwise linear regression analyses. Results: In RIA, the P4 concentrations ranged between 1.1 and 25.4 ng/mL. Regression analyses revealed highly significant (p<0.0001) positive correlations between the three methods applied (M1 vs. RIA: R=0.94; M2 vs. RIA: R=0.98; and M1 vs. M2: R=0.91). Conclusion: The results show that the two commercial on-site methods tested exhibit approximately equal, high consistency with the radioimmunological reference method and can, therefore, be used beneficially in a clinical setting. However, biological interpretation of data must be performed in a method-specific manner.

Tick-Borne Encephalitis Virus (TBEV) Infection in Two Horses.

A final diagnosis in a horse with clinical signs of encephalopathy can be challenging despite the use of extensive diagnostics. Clinical signs are often not pathognomonic and need to be interpreted in combination with (specific) laboratory results and epidemiological data of the geographical region of the origin of the case(s). Here we describe the diagnostic pathway of tick-borne encephalitis virus infection in two horses using established molecular diagnostic methods and a novel in situ hybridization technique to differentiate between regionally important/emerging diseases for central Europe: (i) hepatoencephalopathy, (ii) Borna disease virus, and (iii) West Nile virus infections.

Urogenital Hypoplasia and X Chromosome Monosomy in a Draft Horse Filly.

A 5-month-old draft horse filly was presented with incontinence and severe perivulvar dermatitis, which developed during the previous 2 months. Left-sided ectopic ureter entering in the caudal vaginal lumen, signs of cervix hypoplasia, and urine accumulation in the uterus were found during initial vaginal endoscopy. Therefore, a left ureter-nephrectomy was conducted under general anesthesia. Additionally, a cytogenetic examination was performed, which showed a XO monosomy with a 63,X/64,XX mosaic. This is the first case report presenting a chromosome abnormality in a draft horse filly combined with a left-sided ectopic ureter. Cytogenetic evaluation is recommended in any female horse with developmental abnormalities of the cervix, uterus, ovaries, or with irregularities of estrus.

Survival and fertility of bitches undergoing caesarean section.

BACKGROUND: With the increasing popularity of planned caesarean section, the need for knowledge regarding this surgery has become increasingly important. The reported death and survival rates for caesarean sections vary widely. Another important aspect is the fertility rate in subsequent oestrous after caesarean section. The aim of this study was to investigate the mortality and survival rate of bitches during caesarean section. Additionally, the fertility of bitches after caesarean sections was determined. METHODS: Caesarean sections which were performed in the years 1997-2009 at two university clinics were evaluated retrospectively. A distinction was made between bitches in which a conservative caesarean section was performed and bitches with a caesarean section followed by an ovariohysterectomy. RESULTS: A total of 482 caesarean sections were included in the study. The overall mortality rate was 3.11 per cent, with 2.59 per cent during or after a conservative caesarean section and 4.19 per cent during or after caesarean section with ovariohysterectomy. The reason for ovariohysterectomy was the owner's preference in 63 bitches (47.01 per cent); in 71 (52.98 per cent) bitches, ovariohysterectomy was performed due to a medical indication. The fertility rate after caesarean section was 100 per cent. CONCLUSION: The results show a high mortality rate during and after caesarean section. On the other hand, caesarean section does not seem to have a big impact on further fertility. Further studies are needed to investigate possible reduction of litter sizes and the suitability of caesarean section in subsequent pregnancies.

[Sonographic imaging of physiological ovaries in the dog]. / Die sonographische Darstellung der kaninen physiologischen Ovarien.

Ultrasonography of the canine ovary is a non-invasive examination procedure, which is an important part of the gynaecological examination. For the correct visualisation of the canine ovary, practical experience as well as the correct equipment are important. This article describes the technical requirements, the examination procedure and the appearance of the physiological ovary. The examination can be performed on both a recumbent and standing dog. To find the ovaries, the kidneys can be used as a reference point. The exact size of the ovaries is dependent on the body mass of the dog and the oestrous cycle stage. Particularly in the follicle phase, the detection of the ovaries is facilitated by the functional bodies. Follicles appear as anechoic round structures, which reach a maximum diameter of 6-9 mm. Corpora lutea appear hypoechogenic and protrude over the ovarian surface. In anoestrus, the ovaries are small and of medium echogenicity.

Management of Cleft Palate in Puppies Using A Temporary Prosthesis: A Report of Three Cases.

Cleft palate in dogs is a congenital defect that mostly leads to euthanasia of the affected puppy. If an attempt is made to raise the puppy, it is generally fed via an orogastric tube. Here, we describe the management of cleft palate in three puppies (two Boxers, one Collie) using a customised temporary prosthesis, which allowed the puppies to be bottle-fed and successfully raised by their owners (Cases 2 and 3) and the author (Case 1). The temporary palatal prosthesis was manufactured from a mouthguard intended for human children, which is made of thermoplastic silicone. The preparation procedure was simple and cost-effective. All puppies underwent corrective surgery at 5⁻6 months of age. After surgery, one of the Boxer puppies showed mandibular mesioclusion, while the other two showed no aberrations. All puppies gained the same amount of weight as their littermates, although the weight gain of the two Boxers was slower than that of their littermates. In summary, this case report describes an easy and effective way to raise puppies with cleft palate until corrective surgery can be performed.

Seroprevalence of Neospora caninum-specific antibodies in German breeding bitches.

BACKGROUND: Neospora caninum is an intracellular obligate apicomplexan parasite responsible for multisystemic lesions in dogs. Being definitive hosts and reservoirs, dogs excrete environmentally resistant oocysts. Breeding bitches represent a susceptible dog group and infected bitches may spread this parasite through transplacental transmission. RESULTS: A total of 218 serum samples of German breeding bitches were collected to determine the presence of N. caninum. Antibodies were detected in 16 (7.33%) bitches using a commercial indirect enzyme-linked immunosorbent assay (ELISA). Immunoblotting analysis confirmed all seropositive samples detected by ELISA, proving that the animals were infected with N. caninum. The owners were interviewed regarding breed, age, environment, type, vaccine status, feeding habits and the presence of reproductive disorders. Seropositive animals were between the ages of two to seven years; three of them were kept in kennels while the others were household dogs, one of which was additionally a hunting dog. Owners of four seropositive bitches reported one gestation, while multiple pregnancies had been recorded for the other twelve bitches. Fourteen bitches were regularly vaccinated and six were fed with fresh raw meat. CONCLUSIONS: Although the results confirmed a low incidence of N. caninum seropositive German breeding bitches, further epidemiological and surveillance studies are required to complement our findings regarding the current situation of neosporosis in this specific canine population of Germany.

[Sonographic imaging of physiological ovaries in the cat]. / Sonographische Darstellung der physiologischen Ovarien bei der Katze.

Ultrasound evaluation of the ovaries is an important element of the gynaecological examination. Although it is a well-established method used for many domestic animals, it is an uncommon procedure in cats. This article describes the technical requirements, the examination procedure, and the sonographic appearance of the physiological ovary in the cat. The examination can be performed with the cat in lateral position or dorsal recumbency. Usually the ovaries are found caudal to the kidneys which serve as lead structure. The median size of an ovary in anestrous is 0.9 cm (length) x 0.5 cm (height) x 0.4 cm (width). The ovaries of cyclical (follicular and luteal phase) cats are easier to detect than ovaries of cats in interestrous or anestrous.

Therapy of calcium oxalate urolithiasis in a rhesus macaque (Macaca mulatta).

A rhesus macaque (Macaca mulatta) was presented for anuria. Examination revealed calcium oxalate concrements in the bladder. A cystotomy was performed, and a therapy with alfuzosin was conducted. Over 1 year after the treatment, the rhesus macaque had not shown any more signs of stranguria. This is the first case reporting the successful treatment of urolithiasis in a rhesus macaque.
