42 horses were examined. The physical signs with relation to circulatory insufficiency and the abdominal disease were registered following a two-phased examination procedure. Great prognostic value was found in the degree of circulatory insufficiency judged by pulse rate and character, filling of the jugular vein, skin temperature, colour of mucous membranes, capillary refill time, sweating, depression, skin turgor and degree of enophthalmus. In making a causal diagnosis the abdomen was examined for shape, tenderness, peristaltic sounds, gastric dilation by siphoning, abnormal rectal findings and macroscopic changes in peritoneal fluid. Greatest diagnostic difficulties were encountered in cases of intestinal atonia, acute enteritis and torsion of the colon. In selected (severe) cases laboratory tests were obtained. Blood samples were examined for packed cell volume, hemoglobin, red and white blood cell counts, differential white blood cell count, blood gases and acid-base status, lactate, serum total protein and albumin, plasma sodium, potassium, chloride, calcium, magnesium, inorganic phosphorus, glucose, creatinine, BUN, total bilirubin, ASAT, CK, BASP and GGT. Peritoneal fluid was examined for red blood and white cell counts, total protein, specific gravity, pH and lactate, and enzymes as in blood. Laboratory results generally confirmed the clinical signs of shock, and packed cell volume and blood lactate were regarded to be of greatest prognostic interest. Although the performed laboratory information, macroscopic evaluation was thought to reveal sufficient information in most cases. It was concluded that supervening shock is of decisive importance in severe forms of colic, and that a careful and repeated evaluation of the circulatory insufficiency often provides one with a tentative prognosis although the final diagnosis is not obtained. In spite of therapy fatal outcome was found in all seriously shocked horses.

This study compared the mental health of 12 mothers who had infants with colic to 12 mothers of infants without colic. Colic was defined as infant fussing/crying of at least 2 hours/day for at least 5 out of 7 days, infant cry high-pitched and pain-sounding, and maternal report of infant inconsolability. Mental health was operationalized as scores on the Profile of Mood States and the Symptom Checklist-90R. Mothers of infants with colic had multidimensional psychological distress; they reported more bodily dysfunction, fears, disordered thinking, depression, anxiety, fatigue, hostility, impulsive thoughts and actions; and they had stronger feelings of personal inadequacy or inferiority. Implications for nursing research and practice are discussed in the context of study findings.

Positive end-expiratory pressure (PEEP) was applied in 74 anesthetized, ventilated horses during colic surgery, to attempt to increase arterial oxygen tensions. In 28 horses with an initial PaO2 less than 70 mm of Hg, PEEP increased PaO2 values to a mean of 173 +/- 24 mm of Hg. Arterial oxygen content increased from 14.1 +/- 0.05 ml/dl to 17.2 +/- 0.05 ml/dl. In the remaining 46 horses, PEEP increased PaO2 from a mean value of 101 +/- 6 mm of Hg to 194 +/- 15 mm of Hg, and arterial oxygen content increased from 14.9 +/- 0.09 ml/dl to 16.9 +/- 0.07 ml/dl. Cardiovascular depression and decrease in arterial blood pressure was observed after the application of PEEP in 54 horses. These 54 horses required use of pressors (n = 8), inotropes (n = 32), or both (n = 14) to keep the mean arterial blood pressure greater than 60 mm of Hg. Combined with pharmacologic support of blood pressure, PEEP could be a useful clinical treatment of arterial hypoxemia in horses.

A 12-year-old Morgan gelding was examined for colic of 3 days duration. Signs of depression, colic, diarrhea, and endotoxemia persisted despite aggressive medical therapy and surgical exploration. Culture results from gastric fluid and feces yielded many colonies of Clostridium perfringens. This organism also was recovered from peritoneal fluid 10 days after admission; consequently, the horse was euthanized. At necropsy, a localized gas-filled, necrotic stomach wall was found; many mucosal and submucosal gas blebs were visible. Culture of this tissue yielded Clostridium perfringens. Emphysematous gastritis is a fulminant infection of the stomach wall caused by gas-forming organisms that gain access to the submucosa via mucosal defects such as ulcers. This condition has been reported infrequently in people, and the case reported herein represents the first instance of emphysematous gastritis in the horse.

A four year old Dutch warmblooded mare was born and raised in the province of North-Brabant, the Netherlands. On May 16, 1989, she showed signs of colic, anorexia, depression, ileus, severe dehydration and leukopenia. When the mare collapsed, euthanasia was carried out. Acute colitis and cytoplasmic inclusion bodies in macrophages were observed at autopsy. When an indirect immunofluorescence assay was performed, the Ehrlichia risticii titre of the serum was found to be 1:640.

Twelve light horse geldings developed laminitis within 8 to 12 h of being dosed by nasogastric tube with an aqueous extract of black walnut (Juglans nigra). Four of the 12 horses developed the severe signs of grade 3 laminitis (lame at a walk, refused to lift feet). Laminitis was accompanied by mild depression and limb oedema. There was no evidence of shock or colic. The horses developed neutropenia by 4 h after dosing with the extract, which shifted to a relative neutrophilia by 8 to 12 h. Minimal increases in plasma epinephrine and cortisol concentrations were suggested in severely affected horses. Severe laminitis was characterized by necrosis of dermal tips of dorsal primary epidermal laminae. A proliferative epithelial response in these laminae was distinguished by numerous mitotic figures and clusters of epithelial cells. This evidence suggests that black walnut toxicosis is not only a consistent clinical model, but is also a reliable clinico-pathological and pathological model for study of the pathogenesis and treatment of laminitis.

An outbreak of diarrhoea occurred in a Jersey herd after the introduction of new stock. One of the cows was examined and treated unsuccessfully. Clinical findings included depression, fever, dehydration, congestion, signs of colic and a severe diarrhoea. The post mortem examination revealed emaciation, pseudomembranous enteritis, mesenteric lymphadenopathy and focal disseminated hepatic necrosis. Salmonella typhimurium was isolated from the faeces, mesenteric lymph nodes and liver.

The medical records of 25 horses with intra-abdominal neoplasms and 15 horses with intra-abdominal abscesses were reviewed. Common clinical signs of disease observed by owners of horses in both groups included anorexia, weight loss, fever, signs of colic, and depression. Clinical laboratory abnormalities included leukocytosis, hyperfibrinogenemia, hypoalbuminemia, and hypocalcemia. There was considerable overlap of laboratory test results within and between the 2 groups of horses. Peritoneal fluid was classified as an exudate in 12 of 15 horses with intra-abdominal abscesses and in 14 of 25 horses with intra-abdominal neoplasms. Cytologic examination of peritoneal fluid yielded an accurate diagnosis in 11 of 25 horses with neoplasia and in 3 of 15 horses with abscesses. A mean number of 1.45 cytologic analyses/horse was needed to diagnose neoplasms in the 11 horses in which the analysis was successful in definitively diagnosing the condition.

A number of plants are capable of producing intoxication of sufficient severity as to cause death within 12 hours of the onset of clinical signs. Those most rapid in their lethal effects are the cyanogenic plants and yew. Nitrate-accumulating plants likewise are capable of causing sudden death with only a brief appearance of signs. Most toxic plants, however, typically either require a longer time for the intoxication to develop and become lethal or sudden death is the exception rather than the rule following ingestion. In these cases, diagnosis of the problem may be facilitated by recognition of arrays of clinical signs that appear. Seven major groups of presenting signs can be distinguished: dyspnea and polypnea, hemorrhage, prominent excessive muscular activity, depression and/or weakness, diarrhea and weakness, excessive salivation and/or regurgitation and/or colic, and weakness and incoordination and/or tremors. Based on these and accompanying signs in surviving animals, many of the causes of sudden death can be differentiated. In addition, pathological changes visible on necropsy and identification of plant fragments in the rumen and stomach may be of diagnostic value.

Eight neonatal calves (2 to 21 days old) with suspected abomasal displacement or intestinal obstruction after acute onset of abdominal tympany, colic, depression, or death were referred to Kansas State University for clinical examination or for necropsy. Results of routine hematologic and serum chemical analyses did not reveal consistent changes. Necropsy revealed abomasal distention, with various degrees of abomasitis, hemorrhage, and ulceration, but did not reveal evidence of displaced abomasum or obstructed intestine. Specimens of ruminal contents collected via stomach tube or at necropsy and abomasal contents collected at necropsy were obtained for anaerobic bacteriologic culture. Clostridium perfringens was isolated from all specimens, and on the basis of toxin neutralization tests in mice, 7 were type A and one was type E. Copper concentrations in serum and tissues were within normal limits. It appeared that the acute abdominal syndrome in these neonatal calves was unrelated to copper deficiency, and that C perfringens, particularly type A, may have had an appreciable contributory role in its pathogenesis.
