Epidemiological, clinical, necropsy and histopathological data were accumulated during the study of 15 outbreaks of Senecio spp poisoning in cattle occurring during the last 3 y in the State of Rio Grande do Sul, Brazil. Morbidity averaged 17% and mortality was virtually 100%. The peak mortality occurred during spring and early summer. The most constant clinical signs included anorexia, depression, tenesmus often followed by rectal prolapse, and rough hair coat. Affected animals remained apart from the rest of the herd, lost weight, presented ascites, and had signs of digestive and neurological disturbances. Icterus, photodermatitis, polydipsia, and dependent subcutaneous edema were occasionally noticed. Two main clinical courses could be distinguished. In the protracted form, progressive weight loss terminated with death within many weeks or months. Alternatively, an acute or subacute course led to death in a few days. In both forms, necropsy and histopathological findings included diffuse fibrosis of the liver, hepatomegalocytosis, and biliary hyperplasia. Extrahepatic lesions included gastrointestinal and mesenteric edema, distension, edema and adenomatoid hyperplasia of the gallbladder, and spongy degeneration of the cerebral white matter. S brasiliensis and S oxyphyllus were the species involved in the field outbreaks.

A retrospective analysis of the medical records of 30 consecutive cases of diarrhea occurring in dogs that were hospitalized in a teaching hospital was performed. A prospective analysis of culture results for Clostridium perfringens of dogs with diarrhea were compared with those of a control nondiarrheal group. Hospital-acquired diarrhea in dogs was found to be associated with multiple serotypes of enterotoxigenic Clostridium perfringens. Other potential etiologic agents could not be isolated. Clinical signs were variable, and included mild depression, anorexia, and soft to watery diarrhea with or without frank blood, mucus, and tenesmus. Fever was not present. There were no hematologic or serum biochemical abnormalities, nor were there any consistent virologic or parasitologic findings. Salmonella spp or Campylobacter spp were not identified by fecal culture. No risk factors could be identified. A dog that was euthanatized on the day it developed diarrhea had intestinal histologic findings suggestive of clostridial enteritis. Dogs with diarrhea had significantly higher fecal clostridial counts than did dogs without diarrhea (mean log10 counts +/- SD = 6.34 +/- 1.79 vs 4.75 +/- 2.07). Enterotoxin was found in the feces of 41% of diarrheic dogs but in only 7% of dogs without diarrhea.

Patent ductus venosus was diagnosed in a 10-week-old Holstein heifer with acute onset of collapse and marked tenesmus. Additional clinical signs observed during the course of hospitalization included depression, anorexia, hind limb ataxia, bruxism, and poor growth. Clinicopathologic test results included high blood ammonia concentration, prolonged sulfobromophthalein half-life, and high serum bile acid concentration. Liver biopsy revealed mild periportal fibrosis, but no appreciable hepatocyte atrophy. Mesenteric portography and percutaneous ultrasonography confirmed the patent ductus venosus. An atrial septal defect prosthesis was placed in the ductus venosus, using a catheterization technique. After surgery, however, clinicopathologic test results were unchanged. Ultrasonography revealed that the prosthesis had pulled away from one side of the vessel. When the calf was 10.5 months old, surgical correction was achieved by a transhepatic ligation technique. Ultrasonography confirmed closure of the ductus venosus during and after surgery. Blood ammonia and serum bile acid concentrations and sulfobromophthalein half-life were normal 3 weeks after surgery. The calf had no further episodes of hepatoencephalopathy and was successfully bred at 18 months of age.

One hundred dogs (83 intact males, 15 castrated males, and two intact females) underwent 110 perineal herniorrhaphy procedures. Mixed-breed dogs (n = 32), miniature poodles (n = 14), Boston terriers (n = 11), and Pekingese (n = 9) were represented most frequently. Perineal swelling (n = 48) and a perineal defect on rectal palpation (n = 31) were common clinical signs. Twenty dogs had urinary bladder retroflexion and were significantly more likely to have elevated serum urea nitrogen and creatinine concentrations, hyperkalemia, hyperphosphatemia, and neutrophilic leukocytosis. Only five of 43 dogs evaluated radiographically had prostatomegaly. Of 30 dogs receiving oral barium, all had rectal deviation. The most frequent complications during the hospitalization period were incisional (n = 35), followed by rectal prolapse (n = 9), tenesmus (n = 8), and depression (n = 8). Fifty-six of 70 dogs with follow-up had no complications.

Stage at diagnosis and survival from cancer vary according to where people live, suggesting some may have delays in diagnosis. The aim of this study was to determine if time from presentation to treatment was longer for colorectal and breast cancer patients living further from cancer centres, and identify other important factors in delay. Data were collected on 1097 patients with breast and 1223 with colorectal cancer in north and northeast Scotland. Women with breast cancer who lived further from cancer centres were treated more quickly than those living closer to cancer centres (P=0.011). Multilevel modelling found that this was largely due to them receiving earlier treatment at hospitals other than cancer centres. Breast lump, change in skin contour, lymphadenopathy, more symptoms and signs, and increasing age predicted faster treatment. Screen detected cancers and private referrals were treated more quickly. For colorectal cancer, time to treatment was similar for people in rural and urban areas. Quicker treatment was associated with palpable rectal or abdominal masses, tenesmus, abdominal pain, frequent GP consultations, age between 50 and 74 years, tumours of the transverse colon, and iron medication at presentation. Delay was associated with past anxiety or depression. There was variation between general practices and treatment appeared quicker at practices with more female general practitioners.

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

Three captive-born (5-day-old, 8-day-old, and 4-yr-old) Asian elephants (Elephas maximus) and one captive-born 22-yr-old African elephant (Loxodonta africana) from three private elephant facilities and one zoo in the United States presented with depression, anorexia, and tachycardia as well as gastrointestinal signs of disease including abdominal distention, decreased borborygmi, tenesmus, hematochezia, or diarrhea. All elephants showed some evidence of discomfort including agitation, vocalization, or postural changes. One animal had abnormal rectal findings. Nonmotile bowel loops were seen on transabdominal ultrasound in another case. Duration of signs ranged from 6 to 36 hr. All elephants received analgesics and were given oral or rectal fluids. Other treatments included warm-water enemas or walking. One elephant underwent exploratory celiotomy. Three animals died, and the elephant taken to surgery was euthanized prior to anesthetic recovery. At necropsy, all animals had severe, strangulating intestinal lesions.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease that can involve any aspect of the colon starting with mucosal inflammation in the rectum and extending proximally in a continuous fashion. Typical symptoms on presentation are bloody diarrhea, abdominal pain, fecal urgency, and tenesmus. In some patients, extraintestinal manifestations may predate the onset of gastrointestinal symptoms. A diagnosis of UC is made on the basis of presenting symptoms consistent with UC as well as endoscopic evidence showing continuous and diffuse colonic inflammation that starts in the rectum. Biopsies of the colon documenting chronic inflammation confirm the diagnosis of UC. Most cases are treated with pharmacological therapy to first induce remission and then to maintain a corticosteroid-free remission. There are multiple classes of drugs used to treat the disease. For mild to moderate UC, oral and rectal 5-aminosalycilates are typically used. In moderate to severe colitis, medication classes include thiopurines, biological agents targeting tumor necrosis factor and integrins, and the small-molecule Janus kinase inhibitors. However, in up to 15% of cases, patients in whom medical therapy fails or who have development of dysplasia secondary to their long-standing colitis will require surgical treatment. Finally, to minimize the complications of UC and adverse events from medications, a working collaboration between primary care physicians and gastroenterologists is necessary to make sure that vaccinations are optimized and that patients are screened for colon cancer, skin cancer, bone loss, depression, and other treatable and preventable complications.
