Pyometra, an accumulation of pus in the uterine cavity, occurs rarely in children but should be considered in the differential diagnosis of an intra-abdominal or pelvic abscess. A 10-month-old infant presented with an increasing abdominal mass. She had previous respiratory and diarrheal illnesses. She was underweight, febrile, and tachycardic with an 8×6-cm mobile tender mass in her lower abdomen. Investigations demonstrated leukocytosis and ultrasonogram confirmed a cystic mass. At laparotomy a pyometra was found. Needle aspiration and washout of the uterine cavity were performed but a second procedure was required to place a drain into the cavity. Pyometra occurs rarely in childhood. A review of cases associates a hypoestrogenized endometrium exposed to transient bacteremia with obstruction to uterine drainage. Treatment should include continuous drainage of the uterus.

Pyometra is a clinically relevant problem in intact female cats and dogs. The etiology is similar in both animal species, with the disease caused by bacterial infection of a progesterone-sensitized uterus. Here, we studied pyometra in cats with the aim to describe the incidence and probability of developing pyometra based on age and breed. The data used were reimbursed claims for veterinary care insurance or life insurance claims or both in cats insured in a Swedish insurance database from 1999 to 2006. The mean incidence rate (IR) for pyometra was about 17 cats per 10,000 cat years at risk (CYAR). Cats with pyometra were diagnosed at a median age of 4 years and a significant breed effect was observed. The breed with the highest IR (433 cats per 10,000 CYAR) was the Sphynx, and other breeds with IR over 60 cats per 10,000 CYAR were Siberian cat, Ocicat, Korat, Siamese, Ragdoll, Maine coon, and Bengal. Pyometra was more commonly diagnosed with increasing age, with a marked increase in cats older than 7 years. The mean case fatality rate in all cats was 5.7%, which is slightly higher than corresponding reports in dogs of 3% to 4%. Geographical location (urban or rural) did not affect the risk of developing the disease. The present study provides information of incidence and probability of developing pyometra based on age, breed, and urban or rural geographical location. These data may be useful for designing cat breeding programs in high-risk breeds and for future studies of the genetic background of the disease. Copyright © 2014 The Authors.

Medical management of pyometra in three red wolves (Canis rufus).
Anderson, Kadie; Wolf, Karen N
2013-12-01
Pyometra is a serious, life-threatening disease of both domestic and non-domestic species often requiring ovariohysterectomy to preserve the life of the animal. Medical management of pyometra has been successful in domestic and non-domestic species, and the consideration of such treatment is of marked importance in a critically endangered species. Of the canids, the red wolf (Canis rufus) is second only to African hunting dogs (Lycaon pictus) in terms of the prevalence of both cystic endometrial hyperplasia and pyometra. In this report, three red wolves were medically managed for pyometra. Aside from vaginal discharge, none of the wolves exhibited clinical signs, nor were there reflective inflammatory changes in the laboratory findings. All wolves received standard treatment for pyometra, including prostaglandin F2alpha and antibiotic therapy, while one wolf was more aggressively managed with uterine lavage. Pyometra recurred in two of the treated wolves, while the most aggressively managed wolf continues to show ultrasonographic resolution 2 yr posttreatment. Aggressive medical management of pyometra should be considered a treatment option in certain red wolf females, as it may preserve the animal's reproductive potential.

Blood lactate levels in 31 female dogs with pyometra
Hagman, Ragnvi; Reezigt, Bert Jan; Bergström Ledin, Hanna; Karlstam, Erika
2009-01-01
Background Canine pyometra is a life-threatening disease common in countries where spaying of dogs is not routinely performed. The disease is associated with endotoxemia, sepsis, systemic inflammatory response syndrome (SIRS) and a 3–4% mortality rate. Blood lactate analysis is clinically valuable in predicting prognosis and survival, evaluating tissue perfusion and treatment response in human and veterinary critical care settings. The aims of the present study were to investigate 1) the blood lactate levels of female dogs with pyometra by a hand-held analyser and 2) if these levels are related with the clinical status or other biochemical or hematological disorders. Methods In total 31 female dogs with pyometra admitted for surgical ovariohysterectomy and 16 healthy female control dogs were included in the present study. A complete physical examination including SIRS-status determination was performed. Blood samples for lactate concentrations, hematological and biochemical parameters, acid-base and blood gas analysis and other laboratory parameters were collected and subsequently analysed. The diagnosis pyometra was verified with histopathological examination of the uterus and ovaries. Increased hospitalisation length and presence of SIRS were used as indicators of outcome. Results In the pyometra group the median blood lactate level was 1,6 mmol l-1 (range <0.8–2.7 mmol l-1). In the control group the median lactate level was 1,2 mmol l-1 (range <0.8–2.1 mmol l-1). Of the 31 bitches 19 (61%) fulfilled 2 or more criteria for SIRS at inclusion, 10 bitches (32%) fulfilled 3 of the SIRS criteria whereas none accomplished more than 3 criteria. Lactate levels did not differ significantly between the pyometra and control group, or between the SIRS positive and SIRS negative dogs with pyometra. Increased lactate concentration (>2.5 mmol l-1) was demonstrated in one female dog with pyometra (3%), and was not associated with longer hospitalisation or presence of SIRS

Diverticular disease of the colon presenting as pyometra: a case report.
Pankaja, Susmita; Rrukaj, Astrit; Bathula, Uma
2014-05-04
Pyometra can be caused by various etiologies. We present a rare case of diverticular disease of the colon presenting as pyometra. This type of presentation can be challenging even for an astute clinician. A 74-year-old Caucasian woman with a history of pyometra was referred to our gynecology clinic as an urgent case. She was obese, diabetic and hypertensive. Due to the patient profile and the clinical presentation, clinicians were misled toward a diagnosis of possible endometrial cancer. After further investigations, she was found to have colouterine fistula secondary to a diverticular abscess of the sigmoid colon. Persistent vaginal discharge due to pyometra can be caused by diverticular disease of the colon. Clinicians should be aware of this important differential diagnosis.

Pyometra in captive large felids: a review of eleven cases.
McCain, Stephanie; Ramsay, Ed; Allender, Matthew C; Souza, Carlos; Schumacher, Juergen
2009-03-01
Eleven cases of pyometra were diagnosed in a captive exotic felid collection over 3 yr in seven African lions (Panthera leo), two tigers (P. tigris), one liger (lion-tiger crossbreed), and one leopard (P. pardus). Clinical signs included anorexia, lethargy, vulvar discharge, and vomiting. Diagnosis was based on clinical signs, complete blood cell counts, plasma biochemistry and electrolyte values, radiographs, and abdominal ultrasonography. The most common findings on complete blood count and biochemistry profiles were leukocytosis (>15,000/microL) and hyperproteinemia (>8.2 g/dL) due to increased globulins. Abdominal radiographic findings were largely nonspecific, but ultrasonography routinely showed a distended, fluid-filled uterus. Each case was treated with ovariohysterectomy and systemic antibiotic therapy. Lions were shown to be at an increased risk for developing pyometra compared with other species. Pyometra should be considered as a differential diagnosis in anorexic or lethargic intact female large felids, and ovariohysterectomy may be warranted in nonbreeding female lions.

Septic peritonitis occurs relatively commonly in dogs. Secondary septic peritonitis is usually associated with perforation of intestines or infected viscera, such as the uterus in pyometra cases. The aim of this study was to evaluate the bacterial flora in the ovarian bursae of intact bitches as a potential source of contamination. One hundred forty dogs, clinically suspected of pyometra, were prospectively enrolled. The control group consisted of 26 dogs that underwent elective ovariohysterectomies and 18 dogs with mammary gland tumors that were neutered at the time of mastectomy. Bacteriology samples were taken aseptically at the time of surgery from the bursae and the uterus in all dogs. Twenty-two dogs that were clinically suspected of pyometra had sterile uterine content ("mucometra" cases); the remaining 118 had positive uterine cultures ("pyometra" cases) and septic peritoneal fluid was present in 10% of these cases. Of the 118 pyometra cases, 9 had unilateral and 15 had bilateral bacterial colonization of their ovarian bursae. However, the bacteria from the ovarian bursa were similar to those recovered from the uterine pus in only half of the cases. Furthermore, positive bursae were also seen in one mucometra dog (unilateral) and in four control dogs (two unilateral and two bilateral). The data illustrate that the canine ovarian bursa can harbor bacteria. The biological importance of these isolations remains unclear. Copyright © 2014 Elsevier Inc. All rights reserved.

Canine pyometra is a dioestrus period disease in which systemic inflammatory response syndrome (SIRS) is a common outcome due to the response of the body to the bacterial infection. The purpose of this study was i) to differentiate canine pyometra and cystic endometrial hyperplasia (CEH)/mucometra by measuring serum C-reactive protein (CRP) and prostaglandin F2α metabolite (PGFM) concentrations in blood and ii) to compare serum concentrations of CRP and PGFM in bitches with a pathological uterus (pyometra or CEH/mucometra) to concentrations in bitches with a healthy uterus. Mean CRP concentrations were found significantly higher (p < 0.001) in dogs with pyometra compared to those with CEH/mucometra or healthy uterus. However, no statistical difference could be detected between the groups for mean PGFM concentrations. Mean white blood cell count (WBC), alkaline phosphatase (ALP) and total protein concentrations were found significantly higher (p < 0.001) in dogs with pyometra. Escherichia coli was the most frequently isolated microorganism from dogs with pyometra (64.3%). Edwardsiella spp. was detected in a single case of pyometra for the first time. In conclusion, our results demonstrate that serum CRP concentrations were increased in dogs with pyometra and thus we conclude that serum CRP concentration but not PGFM might be useful as a marker to differentiate a case of CEH/mucometra from pyometra in female dogs. To the authors' knowledge, this is the first report in which Edwardsiella spp. has been isolated in the canine uterus. © 2014 Blackwell Verlag GmbH.

OBJECTIVE: Prevotella bivia is one of the anaerobic bacteria that resides in the flora of the female genital tract. We studied the pathogenicity of P. bivia in a rat pyometra model. METHODS: The experimental animal (rat) model of pyometra was developed to investigate the pathogenicity of P. bivia in a rat pyometra model. RESULTS: In the groups inoculated with aerobes alone, the infection rate was 10% (1/10) in the Staphylococcus aureus- or Staphylococcus agalactiae-inoculated group and 20% (2/10) in the Escherichia coli-inoculated group. Infection was not established in the groups inoculated with anaerobes alone. High infection rates were observed in all the mixed-infection groups. In the S. agalactiae- and Bacteroides fragilis-, S. agalactiae- and P. bivia-, F. coli- and B. fragilis-, and E. coli- and P. bivia-inoculated groups, an infection rate of 100% (10/10) was demonstrated. The efficacy of antibiotics such as flomoxef (FMOX) could be determined using a rat pyometra model. In relation to the alteration of vaginal microbial flora during the menstrual cycle, estrogen increased the growth of P. bivia. CONCLUSION: Mixture of aerobic bacteria and P. bivia increased the pathogenicity of P. bivia. Estrogen would be useful for raising up the inflammatory change of the uterus in experimental models of genital tract infection due to P. bivia. PMID:9702587

Closed cervix is associated with more severe illness in dogs with pyometra.
Jitpean, Supranee; Ambrosen, Aime; Emanuelson, Ulf; Hagman, Ragnvi
2017-01-05
Pyometra, a life-threatening bacterial infection of the uterus, is classified as open or closed depending on the functional patency of the cervix i.e. presence or absence of vaginal discharge. In closed cervix pyometra, pus and bacterial products accumulate in the uterus, which is thought to induce a more severe illness. The aim of this study was to investigate whether disease severity or outcome differed in dogs with open or closed cervix pyometra. Prospectively collected data from 111 female dogs diagnosed with pyometra at the University Animal Hospital, Swedish University of Agricultural Sciences, Uppsala, intermittently during 2005-2012 was analyzed. Seventy-two dogs (65%) had open cervix, whereas 39 dogs (35%) had closed cervix. Differences between the two groups were explored by Wilcoxon Two Sample Test for continuous variables and Chi-square or Fisher's exact test for categorical variables. P < 0.05 was considered significant. In dogs with open cervix the median age was 9.0 years and the median weight 26.0 kg. In dogs with closed cervix the median age was 9.6 years and the median weight 25.0 kg, with no significant differences between the groups (p = 0.69 and 0.24, respectively). Five dogs (4.5%) died, all with open cervix, and 16 dogs (14%) had complications. The general physical condition was moderately or severely depressed in 30% (21/71) of dogs with open cervix (severely depressed in 4 dogs, moderately depressed in 17 dogs) and in 56% (22/39) of dogs with closed cervix (severely depressed in 3 dogs, moderately depressed in 19 dogs). The general physical condition was mildly depressed in 41 dogs with open cervix and 16 dogs with closed cervix, whereas it was normal in nine dogs with open cervix and one dog with closed cervix. None of the included dogs had very severely depressed general physical condition or were non-responsive. Leukocytosis, neutrophilia, monocytosis and moderately to severely depressed general condition was more commonly

2013-01-01
A retrospective cross-sectional study was used to analyse pyometra cases at five RSPCA Animal Hospitals across the UK from 2006 to 2011. A total of 1728 cases of pyometra were recovered from a female dog outpatient caseload of 78,469 animals, giving a total prevalence of 2.2 per cent over the study period. There was an annual increase in the incidence of pyometra within the population, while elective ovariohysterectomy caseload has declined. There were variations in breed and age at presentation. Bullmastiffs (P<0.0001), golden retrievers (P=0.001) and dogue de Bordeaux (P=0.008) were over-represented in the pyometra population when compared with the female dog outpatient caseload. Mean age at presentation was 7.7 years. Some breeds presented at a significantly lower age, including dogue de Bordeaux (mean age 3.3 years) and bullmastiffs (mean age 5.4 years), while others presented as older dogs, including Yorkshire terriers (mean age 9.4 years) and border collies (mean age 10.3 years). Surgical mortality rate at the Greater Manchester Animal Hospital was 3.2 per cent. Pyometra is of significant welfare concern, and also has cost implications, particularly in charity practice. These results serve to highlight this condition so that future change in charity practice caseload can be anticipated and strategies can be directed to improve animal welfare. PMID:24114733

An assay for adenosine deaminase (ADA) was validated in serum and saliva in dogs. Changes in ADA and salivary α-amylase activities were analysed in 26 bitches diagnosed with pyometra and compared with activities in 19 healthy bitches. All animals were classified according to the American Society of Anaesthesiologists (ASA) scoring for physical status. In the validation study, the ADA assay had an imprecision<12% and determination coefficients>0.90 in linearity under dilution experiments, with recoveries of 99.2-114.4%. On the day of presentation, salivary ADA activity was significantly higher in dogs with pyometra than in healthy dogs (median values 7.1IU/L vs. 0.8IU/L, respectively; P<0.01). ADA had a moderate positive correlation with leucocyte and band neutrophil counts, haptoglobin, salivary α-amylase and ASA score, and a low positive correlation with C-reactive protein. There were no significant differences in salivary α-amylase activity between dogs with pyometra and healthy dogs (57.3IU/L vs. 27.4IU/L, respectively). Salivary α-amylase had a low correlation with ASA grade, and leucocyte and band neutrophil counts. In 7/26 bitches with pyometra that were sampled 3 and 10days after ovariohysterectomy, there were no significant changes in α-amylase or ADA activities. These results indicate that ADA activity is increased in the saliva of bitches with pyometra, probably related to systemic inflammation. Copyright © 2018 Elsevier Ltd. All rights reserved.

Actinomyces turicensis Bacteremia Secondary to Pyometra.
Hagiya, Hideharu; Ogawa, Hiroko; Takahashi, Yusuke; Kimura, Kosuke; Hasegawa, Kan; Otsuka, Fumio
2015-01-01
We herein present a rare case of Actinomyces turicensis bacteremia that was caused by pyometra. The patient was successfully treated with transvaginal drainage and antibiotic therapy. A literature review in MEDLINE showed that there have been only 8 previously reported cases of A. turicensis bacteremia. This infection frequently occurs in patients with visceral abscesses, and blood culture examinations usually reveal a polymicrobial pattern. However, the prognosis of such patients has been reported to generally be benign. Due to difficulties in performing bacterial identification and the wide-spectrum clinical pictures associated with this bacteremia, no comprehensive understanding of the clinical features of each Actinomyces species has yet been established.

The occurrence of the pyometra is most common in the first half of the dioestrus when there is decreased cellular immunity associated with increased serum concentration of progesterone in females. The aim of this study was to determine the immunological profile of bitches with pyometra, studying serum levels of IL-2, IL-4, IL-10, IFN-γ, KC-like and TNF-α and comparing them with those of healthy bitches in anoestrus, dioestrus and pregnant. Forty females were divided into four experimental groups: group 1 (G1): with pyometra (n = 10); group 2 (G2): bitches in the second week of gestation (n = 10); group 3 (G3): in anoestrus (n = 10); and group 4 (G4): in dioestrus (n = 10). The serum levels for IL-2, KC-like, INF-γ and TNF-α were similar for all experimental groups. The values obtained for IL-10 were found increased (p < 0.001) in animals in dioestrus and pyometra compared with females in anoestrus and pregnant, and the levels of IL-4 observed were significantly greater (p < 0.001) in bitches with pyometra when compared with others. The cytokine profile in animals with pyometra is similar to bitches in dioestrus for IL-10 and had increase in IL-4 for bitches with pyometra, which represents an anti-inflammatory these cases. This suggests the presence of an immunosuppressive state in both cases, which may explain the propensity of bitches in dioestrus to be affected by pyometra and the severity of the disease on these animals. © 2014 Blackwell Verlag GmbH.

[Pyometra and persistent hymen in an alpaca].
Egloff, C; Gerspach, C; Rütten, M; Dettwiler, M; Reichler, I; Bleul, U
2013-01-01
A 3-year-old female alpaca was referred to the hospital because of tenesmus. Clinical examination revealed a habitual vaginal prolapse with tenesmus during urination and defecation. On vaginoscopic examination a persistent hymen was detected. Ultrasonography of the caudal abdomen showed an echogenic fluid-filled uterus. A diagnostic laparotomy led to diagnosis of pyometra. Following ovariohysterectomy, the recovery was uneventful. One and a half years later the alpaca was again admitted to the hospital because of colic. Based on the findings, a tentative prognosis was provided and the alpaca was euthanized at the request of the owner. At necropsy, a haemorrhagic infarction of a jejunal loop was found due to incarceration in a fibrous adhesion between the vaginal stump and small intestine.

A 7-year-old 42-kg (92.4-lb) sexually intact nulliparous female Italian Mastiff was examined because of a history of vaginal prolapse during diestrus. A physical examination revealed vaginal fold prolapse. Abdominal ultrasonography revealed an enlarged uterus with hypoechogenic content, corpora lutea in the ovaries, and a cyst in the right ovary. Hematologic abnormalities included leukocytosis, neutrophilia, mild anemia, and low Hct. Progesterone and estradiol concentrations were 9.36 ng/mL and 30.42 pg/mL, respectively, in serum and 72.72 ng/mL and 792 pg/mL, respectively, in the ovarian cystic fluid. Ovariohysterectomy was performed; the prolapsed tissue was repositioned by external manipulation and maintained in situ by temporary apposition of the vulvar lips with a retention suture. Anatomic and histologic examinations of the excised tissues revealed pyometra and papillary cystadenocarcinoma in the right ovary. The vaginal hyperplasia completely regressed at 35 days after surgery; 5 months after surgery, the dog's general condition was considered good. Findings in this case were indicative of a hormonally active ovarian papillary cystadenocarcinoma in a female dog in diestrus. Hormone production by the cystadenocarcinoma was the predisposing factor that induced pyometra, mucosal hyperplasia, and vaginal fold prolapse in the dog. On the basis of these concurrent disorders, ovariohysterectomy was an appropriate treatment.

The aim of this study was to investigate the plasma concentrations of folic acid, vitamin B12 and progesterone at different stages of the sexual cycle and pregnancy, during induced abortion and in bitches with pyometra. Bitches (n = 97) were assigned to groups as follows: a) oestrous cycle (n = 42) b) pregnancy (n = 25) c) induction of abortion (n = 10 and d) pyometra (n = 20). Oestrous cycle stages were determined by vaginal inspection and cytology. Pregnancies were estimated by ultrasound (5.0 Mhz; linear transducer; Schimadzu) at days 15-25, 35-45 and 46-63 of pregnancy. Treatments for the induction of abortion were started between days 25 and 35 after mating (5 microg/kg cabergoline daily, Galastop; 5-10 microg/kg Alfaprostol every other day, Gabbrostim). Diagnosis of pyometra was confirmed by ultrasound and vaginoscopy. Folic acid and vitamin B12 concentrations did not differ among different stages of the oestrous cycle. The mean concentration of folic acid during early pregnancy (days 15-25) exceeded levels of later stages (days 46-63): 9.4 +/- 3.7 microg/ml and 4.7 +/- 1.8 microg/ml, respectively (p < 0.01). A positive correlation between folic acid and vitamin B12 was determined in pregnant dogs ( r = 0.925; p < 0.02). Before the induction of abortion, the concentration of folic acid was 9.6 +/- 5.2 microg/ml; during abortion it decreased to 5.0 +/- 3.2 microg/ml (p < 0.01). A significant correlation (r = 0.925; p < 0.02) between progesterone and folic acid was obtained in bitches with abortion. The mean concentration of folic acid in bitches with pyometra significantly differed from that of bitches at different stages of the oestrous cycle (p < 0.05). The mean concentration of folic acid was significantly lower in metoestrous bitches when compared to bitches with pyometra (p < 0.05). The decrease of serum concentrations of folic acid during pregnancy and induced abortion show that fetal growth and abortion caused higher consumption of folic acid

Suspected toxic shock-like syndrome in a dog with closed-cervix pyometra.
Declercq, Jan
2007-02-01
Several cases of toxic shock-like syndrome (TSLS) have been reported in dogs but no inciting cause has been identified. TSLS associated with a closed-cervix pyometra was suspected in the reported bitch. The dog was evaluated for the complaint of generalized dermatopathy (erythema and oedema) and systemic signs with multiorganic involvement (depression, fever, immature neutrophilia, hypoalbuminaemia, renal disease, vomiting and diarrhoea). Histological features consistent with TSLS included superficial dermatitis with epidermal neutrophilic exocytosis and necrotic keratinocytes. The tentative diagnosis of TSLS was based on case history, clinical presentation, laboratory and histopathological findings, and the resolution of all clinical signs following surgical removal of the localized bacterial infection.

Escherichia coli is one of the major causative agents of bovine mastitis worldwide, and is typically associated with acute, clinical mastitis. Besides this, E. coli strains which belong to the extra-intestinal pathogenic group are also the major cause of urinary tract infections and pyometra in dogs. In this study, it was aimed to investigate phylo-groups/subgroups in 155 E. coli isolates obtained from acute bovine mastitis, 43 from urinary tract infections of dogs and 20 from canine pyometra by a formerly described triplex PCR and recently described new quadruplex polymerase chain reaction (PCR) method. Group A1 (n = 118; 76%) and B1 (n = 71; 46%) were found to be the most prevalent groups by triplex and quadruplex PCR assays in mastitis isolates, respectively. Phylo-typing of 43 urinary tract isolates also revealed that most of the isolates belonged to A1 (n = 23; 54%) by triplex and B2 (n = 36; 84%) by quadruplex PCR assays. The isolates assigned as group A1 (n = 17; 85%) by triplex PCR could not be classified by quadruplex PCR in pyometra isolates. The results support the hypothesis that E. coli strains isolated from bovine mastitis cases are environmental. Also, groups C, E and F were identified as new phylo-groups for the first time in acute bovine mastitis cases. The comparison of triplex PCR with quadruplex PCR results revealed that most of the groups assigned in triplex PCR were altered by quadruplex PCR assay.

Pyometra in a Siberian Polecat (Mustela eversmanni)
Johnson, J.D.; Biggins, D.E.; Wrigley, R.H.; Mangone, B.A.; Wimsatt, J.
1999-01-01
A 2-year-old Siberian polecat (Mustela eversmanni) from a breeding colony presented for ultrasound evaluation for pregnancy. It was paired with a male for 2.75 months and had remained absent of pregnancy signs when it was anesthetized and clinically evaluated. Until this time, the animal had eaten well and shown no outward signs of debility. On palpation, the animal had a fluid-filled tubular structure in the caudal abdomen, consistent in location and size with the uterus. No sign of vaginal discharge was present. Ultrasonography revealed 10 fluid-filled evaginations (approximately 12 mm in diameter) of the uterine horns. A presumptive diagnosis of a fluid-filled reproductive tract and likely reproductive failure was made in light of the animal's history, its clinical signs, and the ultrasound findings. Euthanasia was performed because the animal was nonreproductive and might yield information relevant to the breeding colony as a whole. Necropsy of the polecat revealed a distended fluctuant uterus containing mildly odiferous, thick, yellow-green, purulent material. Histopathology confirmed the diagnosis of pyometra. A pure and heavy growth of Enterococcus fecalis was cultured from the uterine contents. In light of results from routine minimal inhibitory concentration antibiotic sensitivity screening, this isolate was resistant to all antibiotics tested in the standard teaching hospital screen.

Mammary cancer and pyometra are important health hazards associated with ovary conservation in pet dogs. Early ovariohysterectomy may reduce the incidence of these two diseases, but an estimate of the extent to which the development of mammary cancer or pyometra adversely influences overall longevity is missing. As a first step toward addressing this knowledge gap, the results of a historical cohort study of Rottweilers that lived in North America are reported. Questionnaires completed by owners and veterinarians were used to obtain lifetime health and medical information on 242 female Rottweilers, including years of lifetime ovary exposure, age at death, and cause of death. To determine the extent to which longevity was shortened in females that developed these ovary-associated diseases, age-anchored life expectancy-defined as the median number of remaining years until death for females alive at specified ages during the life course-and years of life lost, a measure of premature mortality, were estimated. Mammary carcinoma was diagnosed in 19 (7.9%) females; median age at diagnosis was 8.5 years; case fatality was 37%. Pyometra was diagnosed in 16 (6.6%) females; median age at diagnosis was 5.4 years; case fatality was 7%. Median lifetime ovary exposure for the study population was 4.3 years. Although risk for developing both diseases increased with longer ovary exposure, longer ovary exposure (≥4.3 years) was also associated with an overall longevity advantage-a 33% decrease in mortality, living 17 months longer than females with shorter ovary exposure (P=0.002). Analysis of age-anchored life expectancy showed that at no time points during the life course was the current or future diagnosis of mammary carcinoma or pyometra associated with shortened survival compared to females who never developed these conditions. This lack of longevity disadvantage is an expected result for diseases with late-onset, moderate (<50%) case fatality (mammary carcinoma) or low (<10

To determine effects of i.v. administration of hypertonic saline (7.5% NaCl) solution with 6% dextran 70 (HSSD) or isotonic saline (0.9% NaCl) solution (ISS) to dogs with septic shock secondary to pyometra. Prospective, randomized, clinical study. 14 client-owned dogs with septic shock secondary to pyometra. Prior to emergency ovariohysterectomy, catheters were placed in pulmonary and femoral arteries of each dog to evaluate hemodynamic and oxygenation status. Immediately prior to surgery, 7 dogs received HSSD (4 ml/kg [1.82 ml/lb] of body weight, i.v.) and 7 dogs received ISS (32 ml/kg [14.54 ml/lb], i.v.) during a 5-minute period. Measurements of hemodynamic and oxygenation variables were obtained before and 5 and 20 minutes after administration of fluids. Mean arterial pressure (MAP) increased significantly 5 and 20 minutes after administration of HSSD, whereas ISS did not affect MAP. However, cardiac output, cardiac index, and oxygen delivery increased and hematocrit decreased after both treatments. Oxygen consumption and extraction rate and degree of acidosis did not improve after either treatment. Intravenous administration of small volumes of HSSD to dogs with septic shock secondary to pyometra resulted in improvement of hemodynamic and oxygenation status. Although cardiac output, cardiac index, and oxygen delivery improved after administration of a volume of ISS equal to 8 times that of HSSD, MAP increased to > 80 mm Hg only after treatment with HSSD. Administration of HSSD may be an effective treatment for septic shock in dogs.

Progesterone (P4) derivatives which are commonly used to block the cyclicity of domestic cats disturb the endocrine balance in the endometrium. The aims of this study were (i) to examine whether lipopolysaccharide (LPS) is responsible for enhancement of tumor necrosis factor-α (TNFα) secretion by the feline endometrial epithelial and stromal cells in vitro, (ii) to know whether immunolocalization of TNFα/TNFR1 and TNFR2 differs in cats at estrus or diestrus, receiving medroxyprogesterone acetate and suffering from pyometra, and (iii) to determine if TNFα-challenged prostaglandin secretion is stopped by prostaglandin synthases inhibitors. A total of 37 domestic adult cats in estrus or diestrus, receiving octane medroxyprogesterone or having clinical symptoms of pyometra, were enrolled in this study. The results obtained showed a distinct increase in LPS-challenged TNFα secretion in endometrial epithelial, but not stromal cells. TNFα augmented PG secretion was blocked by phospholipase A2 (PLA2) and cyclooxygeanase-2 (COX-2), but not by mitogen-activated protein kinase (MAPK) inhibitor. TNFα/TNFR1 and 2 protein expressions were limited mostly to the surface and glandular epithelium. TNFα/TNFRs protein was upregulated in the inflammatory uterus and hence may be involved in development of pathologic changes in the endometrial glands in cats receiving exogenous P4 as a hormonal contraceptive.

This study was designed to evaluate the role of E. coli α-hemolysin (HlyA) in the pathogenesis of canine pyometra, and on the immune response of canine endometrial epithelial and stromal cells. In Experiment 1, the clinical, hematological, biochemical and uterine histological characteristics of β-hemolytic and non-hemolytic E. coli pyometra bitches were compared. More (p < 0.05) metritis cases were observed in β-hemolytic E. coli pyometra uteri than in non-hemolytic E. coli pyometra uteri. β-hemolytic E. coli pyometra endometria had higher gene transcription of IL-1β and IL-8 and lower gene transcription of IL-6 than non-hemolytic E. coli pyometra endometria (p < 0.01). In Experiment 2, the immune response of endometrial epithelial and stromal cells, to hemolytic (Pyo18) and non-hemolytic E. coli strains (Pyo18 with deleted hlya-Pyo18ΔhlyA- and Pyo14) were compared. Following 4 h of incubation, Pyo18 decreased epithelial cell numbers to 54% (p < 0.001), and induced death of all stromal cells (p < 0.0001), whereas Pyo18ΔhlyA and Pyo14 had no effect on cell numbers. Compared to Pyo18ΔhlyA and Pyo14, respectively, Pyo18 induced a lower transcription level of IL-1β (0.99 vs 152.0 vs 50.9 fold increase, p < 0.001), TNFα (3.2 vs 49.9 vs 12.9 fold increase, p < 0.05) and IL-10 (0.4 vs 3.6 vs 2.6 fold increase, p < 0.001) in stromal cells, after 1 h of incubation. This may be seen as an attempt of hemolytic E. coli to delay the activation of the immune response. In conclusion, endometrial epithelial and stromal cell damage induced by HlyA is a potential relevant step of E. coli virulence in the pathogenesis of pyometra.

Cotton rat ( Sigmodon hispidus) is a useful experimental rodent for the study of human infectious diseases. We previously clarified that cotton rats, particularly females, developed chronic kidney disease characterized by cystic lesions, inflammation, and fibrosis. The present study investigated female-associated factors for chronic kidney disease development in cotton rats. Notably, female cotton rats developed separation of the pelvic symphysis and hypertrophy in the vaginal parts of the cervix with age, which strongly associated with pyometra. The development of pyometra closely associated with the deterioration of renal dysfunction or immunological abnormalities was indicated by blood urea nitrogen and serum creatinine or spleen weight and serum albumin/globulin ratio, respectively. These parameters for renal dysfunction and immunological abnormalities were statistically correlated. These phenotypes found in the female reproductive organs were completely inhibited by ovariectomy. Further, the female cotton rats with pyometra tended to show more severe chronic kidney disease phenotypes and immunological abnormalities than those without pyometra; these changes were inhibited in ovariectomized cotton rats. With regard to renal histopathology, cystic lesions, inflammation, and fibrosis were ameliorated by ovariectomy. Notably, the immunostaining intensity of estrogen receptor α and estrogen receptor β were weak in the healthy kidneys, but both estrogen receptors were strongly induced in the renal tubules showing cystic changes. In conclusion, the close correlations among female reproductive organ-associated abnormalities, immunological abnormalities, and renal dysfunction characterize the chronic kidney disease features of female cotton rats. Thus, the cotton rat is a unique rodent model to elucidate the pathological crosstalk between chronic kidney disease and sex-related factors.

Aerobic bacteria occurring in the vagina of bitches with reproductive disorders.
Bjurström, L
1993-01-01
A retrospective survey was performed of aerobic bacterial species found in the vagina of 203 bitches with genital disorders, e.g. infertility, vaginitis, pyometra and puppy death. Escherichia coli, beta-hemolytic streptococci, Staphylococcus intermedius and Pasteurella multocida were the species most often isolated. From bitches with pyometra E. coli in pure culture was the most frequent isolate. In contrast, the majority of infertile bitches gave rise to mixed cultures, and no specific bacterial species was consistently associated with infertility. Thus, bacterial sampling from infertile bitches was concluded to be of low diagnostic value. Bacterial species isolated from the bitches having vaginitis were present in pure culture in 26.9% of the samples while nonspecific mixed cultures were obtained from 34.6% of the samples from these bitches. E. coli was the most frequently isolated bacterial species from bitches with dead puppies. However, in such cases it is important to relate the vaginal bacterial findings to autopsy findings and the results of bacteriological cultures of the pups.

Primary Endometrial Squamous Cell Carcinoma In Situ: Report of a rare disease.
Jetley, Sujata; Jairajpuri, Zeeba S; Hassan, Mohammad J; Madaan, Garima; Jain, Reena
2015-11-01
Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year's duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

alpha-1-acid glycoprotein (AGP) is an acute-phase protein and a serum marker of inflammation and neoplasia in humans. AGP concentrations in diseased dogs and the potential effects of age, breed, and sex have not been elucidated. The purpose of this study was to examine differences in AGP concentration based on age, sex, and breed in a large population of clinically healthy dogs and to compare AGP concentrations in dogs with various diseases. Serum was obtained from clinically healthy puppies (n=74) and adults (n=172) of both sexes, and included mongrels (n=205) and Beagles (n=41). Serum also was obtained from 192 dogs with various diseases, including 8 with pyometra that were sampled before, and 1, 2, 3, and 10 days after surgery. AGP concentration was measured by single radial immunodiffusion. Statistical comparisons were made among age, sex, breed, and disease groups. Serum AGP in healthy adult mongrels was 364+/-106 mg/L (reference interval, 152-576 mg/L). AGP was lowest in newborns (n=11, 122+/-54 mg/L) and gradually increased to adult levels by 3 months of age. Median AGP concentration was highest in dogs with parvovirus (n=17, 2100 mg/L), distemper (n=7, 1250 mg/L), and pyometra (n=18, 2480 mg/L) and was also significantly higher in dogs with acute filariasis, renal failure, urolithiasis, pancreatitis, hepatitis, trauma, hyperadrenocorticism, and immune-mediated hemolytic anemia. Dogs with acute filariasis and acute hepatopathy had significantly higher AGP concentrations than dogs with chronic filariasis and chronic hepatopathy. Serum AGP concentration decreased gradually following surgery for pyometra but remained increased after 10 days (896+/-175 mg/L). Because of significantly lower AGP in puppies, the age of dogs should be considered when using AGP as a marker of disease. Serum AGP may be a useful marker of inflammatory disease in dogs and may help differentiate acute and chronic stages of disease.

This article discusses different techniques that can be used in the diagnosis and treatment of obstetrical emergencies. Female reproductive emergencies commonly encountered by small animal practitioners include pyometra, dystocia, cesarean section, mastitis, eclampsia, uterine torsion, and uterine prolapse. A thorough knowledge of normal and abnormal reproductive behavior will aid the emergency veterinarian in successfully managing such cases. Timely diagnosis and treatment of these emergencies will often give a good outcome.

We present here the case report of a postmenopausal woman who complained of recurrent pus-like vaginal discharge and perianal pain 1 year after Le Fort colpocleisis, which was subsequently identified as a primary invasive carcinoma of the vagina. Biopsy confirmed a squamous cell carcinoma in the vagina, and the disease was classified as stage III according to FIGO staging. The patient received pelvic radiotherapy. This case emphasizes that differential diagnosis of recurrent vaginal discharge that presents remote from obliterative procedure for pelvic organ prolapse should consider not only pyometra, but also other causes.

Transrectal ultrasonography, electroejaculation and cryopreservation of spermatozoa were applied to the African wild dog (Lycaon pictus) to establish non-invasive protocols for assessing the reproductive health of one of the most endangered African canids. Transrectal ultrasonography was performed on immobilized male (n = 2) and female (n = 5) captive wild dogs. The testes and epididymides of the male dogs were imaged transcutaneously, followed by electrostimulation and cryopreservation of spermatozoa. The sonomorphology of the female and male urogenital tracts was characterized. In females, the vagina, cervix, non-pregnant uterus and ovary were imaged and the reproductive health of each female was evaluated. The sonographic assessment helped to identify one pyometra and extensive abdominal fat deposits in two other individuals in which pyometra had been suspected. Images of the adrenal glands showed differences in size among individuals of the same breeding group. Whether these differences were related to the dominance hierarchy remains to be determined. In males, visualization of the prostate gland, testis and epididymis indicated sexual maturity. Three ejaculatory fractions (1.0, 1.5 and 0.5 ml, with 50, 95 and 95% motility, respectively; 1.125 x 10(8) spermatozoa per ejaculate) were collected from one male. The motility of each of these fractions after thawing was 0, 30 and 40%, respectively. Electrostimulation of the second male, in which a cystic structure in a testis had been identified by sonography, resulted in an aspermic ejaculate (0.5 and 1.0 ml). These technologies provided basic data on reproduction in female and male African wild dogs and were an efficient way to evaluate reproductive health.

Magnetic resonance imaging (MRI) of abnormal uterine masses.
al-Ahwani, S; Assem, M; Belal, A; Abdel-Hamid, H
1991-01-01
Sixteen women with clinically diagnosed uterine masses were studied by magnetic resonance imaging (MRI). Pelvic study was carried out in the coronal, sagittal and axial planes. Uterine leiomyomas were detected in 12 cases, while the remaining cases were one each of uterine sarcoma, invasive molar pregnancy, cervical malignancy with pyometra and haematometra with congenital cervical stenosis. The uterine origin of the masses could be clearly detected in all patients, as well as the nature of the masses, the presence of degenerative or malignant changes and the nature of the intrauterine fluid. MRI characteristic findings of the studied masses are presented and discussed.

Prostaglandins and reproduction in female farm animals.
Weems, C W; Weems, Y S; Randel, R D
2006-03-01
Prostaglandins impact on ovarian, uterine, placental, and pituitary function to regulate reproduction in female livestock. They play important roles in ovulation, luteal function, maternal recognition of pregnancy, implantation, maintenance of gestation, microbial-induced abortion, parturition, postpartum uterine and ovarian infections, and resumption of postpartum ovarian cyclicity. Prostaglandins have both positive and negative effects on reproduction; they are used to synchronize oestrus, terminate pseudopregnancy in mares, induce parturition, and treat retained placenta, luteinized cysts, pyometra, and chronic endometritis. Improved therapeutic uses for prostaglandins will be developed when we understand better their involvement in implantation, maintenance of luteal function, and establishment and maintenance of pregnancy.

Ovariohysterectomy in the Bitch
Bencharif, Djemil; Amirat, Lamia; Garand, Annabelle; Tainturier, Daniel
2010-01-01
Ovariohysterectomy is a surgical procedure widely employed in practice by vets. It is indicated in cases of pyometra, uterine tumours, or other pathologies. This procedure should only be undertaken if the bitch is in a fit state to withstand general anaesthesia. However, the procedure is contradicated if the bitch presents a generalised condition with hypothermia, dehydration, and mydriasis. Ovariohysterectomy is generally performed via the linea alba. Per-vaginal hysterectomy can also be performed in the event of uterine prolapse, if the latter cannot be reduced or if has been traumatised to such an extent that it cannot be replaced safely. Specific and nonspecific complictions can occur as hemorrhage, adherences, urinary incontinence, return to oestrus including repeat surgery. After an ovariectomy, bitches tend to put on weight, it is therefore important to inform the owner and to reduce the daily ration by 10%. PMID:20224801

Cefovecin (Convenia) for the treatment of septic peritonitis in a female lion (Panthera leo).
Steeil, James; Schumacher, Juergen; Seibert, Rachel; Tobias, Karen
2012-09-01
An 8-yr-old intact female African lion (Panthera leo) presented with a 3-day history of lethargy, anorexia, and vomiting. Hematologic and biochemical abnormalities included a leukocytosis, 41,700/microl (4,700-15,300) with a neutrophilia (37,530/microl; 2,000-9,200) and a left shift (1,250/microl bands; 0-300), and mild hypokalemia of 2.1 mEq/L (2.8-4.8). Abdominal radiographs revealed evidence of intestinal ileus, peritonitis, and the presence of effusion. An exploratory laparotomy was performed, and septic peritonitis due to a pyometra was diagnosed. The lion was treated with an ovariohysterectomy, abdominal lavage, fluid therapy, and a subcutaneous injection of cefovecin. The lion recovered, and clinical signs associated with septic peritonitis resolved within 36 hr. It was returned to conspecifics 3 wk later. Three months postoperatively, the lion showed no residual signs of septic peritonitis.

Abstract Patients with total placenta previa and past history of cesarean delivery often experience overwhelming hemorrhage during childbirth. In order to control intraoperative and postoperative bleeding, we propose a novel multifaceted spiral suture of the lower uterine segment which directly sutures the bleeding site. To evaluate the efficacy and safety of multifaceted spiral suture, a retrospective study was conducted using data from 33 patients with total placenta praevia and caesarean history. All participants underwent multifaceted spiral suture and no patient experienced uncontrollable bleeding or underwent hysterectomy. The average blood loss of all patients involved was 1327.3 ± 1244.1 mL. Five patients reported blood loss exceeding 3000 mL (15.15%), and the highest reached to 4000 mL. No complications such as fever, pyometra, synechiae, or uterine necrosis were observed. Three cases (3/33, 9.09%) reported hematuria in the first 3 days following surgery and spontaneous resolution were observed within 3 to 7 days following insertion of indwelling catheters. No complaints were received during 6-month follow-up visits. These findings suggest that multifaceted spiral suture is a practical, feasible, and promising technique in potentially minimizing postpartum bleeding and avoiding hysterectomy for patients with placenta praevia or accrete.

Aglepristone: A review on its clinical use in animals.
Gogny, Anne; Fiéni, Francis
2016-03-01
Aglepristone (RU 46534) is a competitive progesterone antagonist that is indicated for the treatment of various progesterone-dependent physiological or pathologic conditions. Aglepristone has proven to be an effective means of terminating pregnancy in most species. When used to induce parturition, aglepristone was effective in all cases in the bitch, cow, and goat, with no apparent adverse effects on neonatal health or milk production. When used to schedule an elective cesarean section, aglepristone treatment was deemed safe for dams and puppies, providing that the ovulation date had been accurately assessed at the time of breeding. Irrespective of the stage of pregnancy at injection, treatment with aglepristone has no apparent negative effects on subsequent fertility. Aglepristone is also a safe and relatively effective means of treating pyometra. However, given the high level of septic risk and the likelihood of rapid deterioration, such therapy is not recommended in emergency situations. Treatment of feline fibroadenomatosis using aglepristone has given promising results, but repeat treatment may be necessary in cats previously treated with long-acting progestagens. The use of aglepristone in other progesterone-dependent diseases has yet to be fully evaluated but may prove valuable, especially in the treatment of insulin-resistant diabetes mellitus, acromegaly, and the treatment of some vaginal tumors in the bitch.

Formerly, Arcanobacterium pyogenes was recently renamed Trueperella pyogenes. This opportunistic bacterium is related to miscellaneous pyogenic infections in animals. Most studies involving T. pyogenes are case reports, whereas few surveys have focused the major aspects of T. pyogenes infections involving a case series study design. The aim of this study was to retrospectively evaluate selected epidemiological and clinical aspects, as well as the in vitro antimicrobial susceptibility pattern of 144 cases of T. pyogenes infections among domestic animals from 2002 to 2012. T. pyogenes was isolated from different clinical specimens from cattle, goats, sheep, pigs, horses, dogs, and buffaloes. Correlations were assessed by the Chi-square or Fisher's exact tests. Mastitis (45.1%), abscesses (18.0%), pneumonia (11.1%), and lymphadenitis (9.0%) were the most common clinical manifestations. In addition, the organism was also isolated from other miscellaneous clinical specimens from cases of septicemia, encephalitis, pyometra, prostatitis, orchitis, seminal vesiculitis, pericarditis, and omphalitis. No statistical association was observed between T. pyogenes infections and age, gender, or season across the study. The most effective drugs against the pathogen were florfenicol (99.1%), cefoperazone (96.0%), cephalexin (95.0%), and ceftiofur (94.8%). High resistance rates were observed against trimethoprim-sulfamethoxazole (49.3%), followed by norfloxacin (10.9%) and tetracycline (9.2%). This study highlights the diversity of clinical manifestations and the opportunistic behavior of T. pyogenes infections in domestic animals, with predominance of mastitis, abscesses, pneumonia, and lymphadenitis. It also reinforces the importance of knowing the susceptibility profile before initiating therapy, to improve antimicrobial therapy approaches.

Evaluation of automated assays for immunoglobulin G, M, and A measurements in dog and cat serum.
Tvarijonaviciute, Asta; Martínez-Subiela, Silvia; Caldin, Marco; Tecles, Fernando; Ceron, Jose J
2013-09-01
Measurements of immunoglobulins (Igs) in companion animals can be useful to detect deficiencies of the humoral immune system, that can be associated with opportunistic or chronic infections, or other immune-mediated disorders including B-cell neoplasms. The purpose of this study was to evaluate commercially available automated immunoturbidimetric assays designed for human IgG, M, and A measurements in canine and feline serum using species-specific calibrators. Canine and feline serum samples with different IgG, M, and A concentrations were used for the analytical validation of the assays. Intra- and inter-assay precision, linearity under dilution, spiking recovery, and limit of detection were determined. In addition, effects of lipemia, hemolysis, and bilirubinemia were evaluated. Finally, Ig concentrations were determined in small groups of diseased dogs and cats, and compared with healthy groups. Spiking recovery and linearity under dilution tests showed that the assays measured Igs in canine and feline serum samples precisely and accurately. Intra- and inter-assay imprecisions were lower than 15% in all cases. Significantly higher IgG, IgM, and IgA levels were observed in dogs with leishmaniasis, while dogs with pyometra showed a statistically significant increase in IgM and IgA concentrations in comparison with healthy dogs. Significantly higher IgG and IgM levels were observed in FIV-infected cats compared with healthy ones. The automated human Ig assays showed adequate precision and accuracy with serum samples from dogs and cats. Also, they were able to discriminate different concentrations of Igs in healthy and diseased animals. © 2013 American Society for Veterinary Clinical Pathology.

This paper presents the successful use of a non-surgical, transcervical uterine lavage technique for the treatment of uterine infection-induced infertility in three female large cats. We developed a non-surgical uterine lavage technique, which allowed repeated flushing of the uterine lumen and installation of therapeutic antibiotics. The entire procedure was performed under general anaesthesia (duration of anesthesia ranged from 40 to 70 min). It was successfully applied in a Sumatran tiger (Panthera tigris sumatrae), a Corbett tiger (Panthera tigris corbetti) and an Amur leopard (Panthera pardus orientalis). The tigers were treated only once, whereas the leopard received four uterine treatments, due to re-infection after mating. Decisions to conduct uterine treatments were based on detection of uterine fluid during previous transrectal ultrasound examinations. The catheter was guided into the vagina, with the aid of an endoscope, passing the urethra, and then into the uterus, with the aid of transrectal ultrasonography. Both uterine horns were separately flushed with approximately 300 mL of cell medium M199, followed by an antibiotic infusion. Upon ultrasonographic re-examination, the topical uterine treatments resulted in an apparent decline in the inflammatory and/or degenerative processes. The Corbett tiger had the most severe uterine alterations, in addition to an aseptic pyometra. As a result, she was treated 1 month prior to ovariohysterectomy (in order to reduce the surgical risk). The Sumatran tiger was artificially inseminated twice after hormone-induced estrus, and the Amur leopard expressed a spontaneous estrus and re-initiated mating behaviour.

OBJECTIVE To characterize clinical and laboratory findings in cats with naturally occurring sepsis, emphasizing hemostasis-related findings, and evaluate these variables for associations with patient outcomes. DESIGN Prospective, observational, clinical study. ANIMALS 31 cats with sepsis and 33 healthy control cats. PROCEDURES Data collected included history; clinical signs; results of hematologic, serum biochemical, and hemostatic tests; diagnosis; and outcome (survival vs death during hospitalization or ≤ 30 days after hospital discharge). Differences between cats with and without sepsis and associations between variables of interest and death were analyzed statistically. RESULTS The sepsis group included cats with pyothorax (n = 10), septic peritonitis (7), panleukopenia virus infection (5), bite wounds (5), abscesses and diffuse cellulitis (3), and pyometra (1). Common clinical abnormalities included dehydration (21 cats), lethargy (21), anorexia (18), pale mucous membranes (15), and dullness (15). Numerous clinicopathologic abnormalities were identified in cats with sepsis; novel findings included metarubricytosis, hypertriglyceridemia, and high circulating muscle enzyme activities. Median activated partial thromboplastin time and plasma D-dimer concentrations were significantly higher, and total protein C and antithrombin activities were significantly lower, in the sepsis group than in healthy control cats. Disseminated intravascular coagulopathy was uncommon (4/22 [18%] cats with sepsis). None of the clinicopathologic abnormalities were significantly associated with death on multivariate analysis. CONCLUSIONS AND CLINICAL RELEVANCE Cats with sepsis had multiple hematologic, biochemical, and hemostatic abnormalities on hospital admission, including several findings suggestive of hemostatic derangement. Additional research including larger numbers of cats is needed to further investigate these findings and explore associations with outcome.

This study was undertaken to verify the clinical signs, incidence, location, etiology and pathology of ovarian hydrobursitis in infertile female camels and estimate the fertility after unilateral surgical ablation. Genital organs (n = 124) were examined in camels slaughtered at Makkah abattoir during Hajj of 2009. Infertile female camels (n = 142) presented for management to the Veterinary Teaching Hospital, Qassim University, Saudi Arabia, were clinically examined and ultrasound-scanned for the diagnosis of genital abnormalities. Twenty eight camels diagnosed with ovarian hydrobursitis were further investigated for the effect of unilateral surgical ablation on breeding outcomes. Surgical ablation was carried on 14 cases (treated group), the remaining 14 cases were followed as controls (control group). Both groups were observed for breeding results: 90 days non-return rate (90d NRR) and calving rate (CR). Removed bursae were sent to the laboratory for histopathological investigation. Results showed that the incidence of ovarian hydrobursitis was 6.5% in slaughtered camels and 33.8% in infertile females. Camels with hydrobursitis were concurrently affected with pyometra, uterine and vaginal adhesions or purulent endometritis. Histopathology reported degeneration and hyperplasia of the lining epithelium, mononuclear cells infiltration, focal aggregation of inflammatory cells, cystic dilatation of multi-acinal structures, tiny hemorrhages, and presence of hemosiderin-laden macrophages. The 90d NRR and CR of the surgically-treated cases were 64.3% and 50%, respectively. None of the untreated cases conceived. These results confirmed that ovarian hydrobursitis causes infertility in dromedary female camels and is associated with inflammatory genital conditions and surgical ablation in unilaterally affected animals presents a potential treatment.

OBJECTIVE To compare outcomes for laparoscopic ovariectomy (LapOVE) and laparoscopic-assisted ovariohysterectomy (LapOVH) in dogs. DESIGN Retrospective case series. ANIMALS 278 female dogs. PROCEDURES Medical records of female dogs that underwent laparoscopic sterilization between 2003 and 2013 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of the surgical procedure, durations of anesthesia and surgery, intraoperative and immediate postoperative (ie, during hospitalization) complications, and short- (≤ 14 days after surgery) and long-term (> 14 days after surgery) outcomes were recorded. Data for patients undergoing LapOVE versus LapOVH were compared. RESULTS Intraoperative and immediate postoperative complications were infrequent, and incidence did not differ between groups. Duration of surgery for LapOVE was significantly less than that for LapOVH; however, potential confounders were not assessed. Surgical site infection was identified in 3 of 224 (1.3%) dogs. At the time of long-term follow-up, postoperative urinary incontinence was reported in 7 of 125 (5.6%) dogs that underwent LapOVE and 12 of 82 (14.6%) dogs that underwent LapOVH. None of the dogs had reportedly developed estrus or pyometra by the time of final follow-up. Overall, 205 of 207 (99%) owners were satisfied with the surgery, and 196 of 207 (95%) would consider laparoscopic sterilization for their dogs in the future. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that short- and long-term outcomes were similar for female dogs undergoing sterilization by means of LapOVE or LapOVH; however, surgery time may have been shorter for dogs that underwent LapOVE. Most owners were satisfied with the outcome of laparoscopic sterilization.

Neutrophil cytoplasmic toxicity is manifested as an abnormality in cell size or the cytoplasmic content upon examination of Romanowsky-stained blood smears, and is traditionally associated with infection and inflammation. The purpose of this retrospective study was to investigate the association of such changes with clinical and clinicopathologic characteristics, diseases, and prognoses in dogs. Dogs with neutrophil toxicity (n = 248) were compared with negative controls (n = 248). Statistical analyses included chi-square tests, independent t-tests, nonparametric Mann-Whitney tests, the chi-square trend test, and survival analysis. Dogs with neutrophil toxicity had a significantly higher prevalence of pale mucous membranes, tachycardia, fever, abdominal organomegaly, icterus, melena, and hematuria. Most mean hematologic variables were significantly different between groups. Dogs with neutrophil toxicity had a significantly (P < .05) higher prevalence of leukocytosis, leukopenia, neutrophilia, neutropenia, anemia, hyponatremia, hypokalemia, hypoproteinemia, hypoalbuminemia, and hypocalcemia. The prevalence of pyometra, parvovirus infection, acute renal failure, peritonitis, immune-mediated hemolytic anemia, disseminated intravascular coagulation, pancreatitis, septicemia, and neoplastic disorders was significantly higher among these dogs. Case fatality, hospitalization length, and treatment cost were significantly (P < .001) higher in dogs with neutrophil toxicity. Neutrophil toxicity severity was significantly (P < .0035) and positively associated with neutropenia, and negatively associated with leukocytosis and neutrophilia. A significant trend (P = .05) toward increasing case fatality with an increase of neutrophil toxicity was observed. In the neutrophil toxicity group, dogs with leukopenia (<5.0 X 10(3)/mm3) had a significantly (P < .0001) higher case fatality compared to dogs with normal or high leukocyte counts. We conclude that evaluation of blood smears for

The objectives of the study were to characterize an ultrasound reproductive tract scoring (URTS) system to assess suitability for breeding in dairy cows, to describe the prevalence of these scores in commercial dairy herds and to examine their relationship with subsequent fertility. Ultrasound examinations (7797) were performed on 5751 Holstein-Friesian cows prior to breeding in 62 seasonally calving herds over 2 years. Data recorded from images of both ovaries and the uterus were combined into a six point scoring system and the prevalence of cows with cystic ovarian follicles and uterine abscesses and adhesions was recorded separately. The prevalence of ovulatory cows which had completed uterine involution (score 1), or had mild (2) or moderate endometritis (3) was 62.5%, 21.7% and 2.2%, respectively. The prevalence of anovulatory cows with moderate endometritis (4), ovulatory cows with pyometra (5) and anovulatory cows which had completed uterine involution (6) was 3.3%, 2.2% and 8.1%, respectively. The interval between calving and examination differed between cows with each of the scores 1, 2, 5 and 6 (61, 46, 53 and 50 days, respectively, p < 0.05) but not between cows with scores 3 and 4 (37 and 35 days, respectively). Ovulatory cows which had completed uterine involution (score 1) had a higher likelihood of pregnancy to first service than ovulatory or anovulatory cows which had not completed uterine involution (p

The aim of this study was to characterize the clinically relevant genital tract disorders of dromedary camels. Reproductive tract examinations were performed via transrectal palpation, ultrasonography and vaginal exploration. The ultrasonic appearance of the reproductive pathology was described and compared with its morphology at laparotomy, after surgical removal, during postmortem examination or upon slaughter. Diagnosis was also confirmed by histopathology. The most frequently encountered follicular structures were larger than typical follicles (56/338, 16.6%) having three echo textures: 1) thin walls and clear hyperechogenic content (11.6%); 2) thick walls and few fibrous trabeculae (33.7%); and 3) thick walls and many echogenic transecting fibrinous strands (54.7%). Corpora lutea with non-echoic central cavity (5/31, 16.1%) were greater in diameter than those with no cavity (26/31, 83.9%) (P=0.03). A granulosa cell tumor (1/338, 0.3%) was multilocular and honeycombed in shape. Presence of a large, well-demarcated, hypoechogenic sac lateral to or beneath the uterine horn encasing the ovary was diagnostic for ovarian hydrobursitis (102/338, 30.2%). Hydrosalpinx and pyosalpinx (6/338, 1.8%) were beaded in appearance, with the ovary located outside these structures. Clinical endometritis/cervicitis (122, 36.1%) was characterized by changes in the homogeneity in about half of the cases. A greatly dilated uterus with clear, hypoechogenic or echogenic contents with signs of hydrometra and pyometra, respectively, was another categorization of a reproductive pathology (24/338, 7.1%). Highly reflective, linear structures were observed in cases with intrauterine fetal bone retention (1/338, 0.3%). In conclusion, reproductive pathologies in dromedary camels can be efficiently imaged by use of ultrasonic technologies, thus familiarizing the practitioner with these disorders and facilitating application of these technologies so that suitable treatment can occur is important

is necessary for induction of a response to (an) epitope(s) in TF-LPG and TF1.17. Furthermore, vaginal fluid from T. foetus-infected heifers and serum from a cow with a T. foetus-associated pyometra recognized both TF1.17 and TF-LPG in western blots. These results suggest that T. foetus LPG and SGA2 are related to TF1.17 antigen, which was previously shown to play an important role in the pathogenesis and host response in bovine trichomoniasis.
