Objective – To describe the diagnostic procedures, therapeutic management and successful outcome of a case of anaphylaxis induced by the inadvertent intravenous (IV) administration of mare's milk to a neonatal foal. Case Summary – A 3‐day‐old Thoroughbred colt was presented for treatment of bilateral flexural limb deformities of the forelimbs. Because the foal was unable to ambulate initially, mare's milk was administered via nasoesophageal tube feedings during treatment of the musculoskeletal disorder. Anaphylaxis resulted after unintentional administration of a bolus of 150 mL of mare's milk through a jugular catheter. Aggressive therapy for anaphylaxis and careful monitoring resulted in the successful recovery of the foal after 9 days of intensive care. New or Unique Information Provided – This case is the first published report to describe the effects of accidental IV administration of mare's milk to a neonatal foal. Medical errors are commonly reported in pediatric medicine; the intent of this report is to raise awareness of medical errors and student education in equine medicine as well as describe the therapy and outcome of anaphylaxis induced by IV administration of mare's milk in a neonatal foal. 相似文献

Stress hyperglycemia in cats 总被引:1,自引:0,他引:1

It may be difficult to differentiate the possible causes of hyperglycemia in the cat. The following investigation was on transient hyperglycemia in 320 cats. The frequency and degree of stress-hyperglycemia and its relation to different types of primary diseases was proven. Animals with overt diabetes mellitus or pancreatic diseases were not included in this study. Plasma glucose was analyzed with the o-Toluidine- or with the glucose oxidase-method. Plasma immune-reactive insulin (IRI) was estimated by RIA. A glucose concentration of greater than or equal to 140 mg/dl (7.77 mmol/l) in the fasted animal was defined as hyperglycemia. The results of the retrospective investigation show in cats transient hyperglycemia occurs more often (3.2%) than permanent hyperglycemia (0.57%). Contrary to overt diabetes mellitus there is no sex- or age-related predisposition. Glucose values above 300 mg/dl (16.65 mmol/l) with maximal values up to 620 mg/dl (34.42 mmol/l) were estimated in 12% of the animals. In 12 from 19 hyperglycemic animals the basal IRI values were between 4 and 14 microU/ml, 11 animals had a lowered I/G ratio. In the following order of frequency the primary diseases found in combination with transient hyperglycemia were: dys- and stranguria, viral and bacterial infections, gastrointestinal diseases, neoplasia, renal insufficiency, cardiopathies etc. With improvement of the underlying disturbance the stress-related hyperglycemia normalized without insulin therapy within a few days. In conclusion, it is necessary to initially identify basic diseases that may trigger the onset of stress-hyperglycemia in the cat. Neither the extent of the glucose level nor a single plasma-insulin-value are valid indicators of confirming the diagnosis of diabetes mellitus.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

A newborn foal was presented because it was unresponsive and in cardiopulmonary arrest. Aggressive cardiopulmonary cerebral resuscitation was administered to the foal, which revived the foal; however, acute renal failure developed. Fluid retention and azotemia occurred although the foal was alert and able to suckle. A 6‐hour renal replacement therapy session using hemodiafiltration and a continuous renal replacement therapy machine was administered to the foal at 3 days of age which lowered the foal's azotemia and facilitated removal of some of the excess body fluid. Despite therapy, the foal developed pulmonary edema and was euthanized. Although the foal in this case did not survive, this report highlights the possibility of developing postresuscitation complications such as acute renal failure and describes the use of renal replacement therapy using hemodiafiltration as a viable option in neonatal foals with acute kidney injury. 相似文献

Thirteen cats with diabetes mellitus were evaluated. Clinical signs included polydipsia, polyuria, polyphagia, lethargy, and weight loss. Results of physical examination included obesity, hepatomegaly, mild seborrhea sicca, muscle wasting, and dehydration. One cat walked plantigrade and was suspected of having a diabetic neuropathy. Persistent hyperglycemia, glucosuria, high liver enzyme activities, hypercholesterolemia, hyperproteinemia, and low electrolyte concentrations were the common laboratory findings. In 3 cats diabetes mellitus developed after megestrol acetate therapy; 2 of these cats required only temporary insulin treatment. In a 3rd cat, which had no history of receiving diabetogenic drug therapy, remission of diabetes mellitus also was observed. Serum insulin and plasma glucose concentrations were determined in 6 cats after administration of an intermediate-acting insulin (isophane insulin) and in 3 cats after administration of a long-acting insulin (protamine zinc insulin). The insulin concentration peaked 2 to 6 hours after the injection of intermediate-acting insulin and 6 to 12 hours after the injection of long-acting insulin. The lowest glucose concentration was recorded 4 to 8 hours after injection of intermediate-acting insulin, and 6 to 12 hours after injection of long-acting insulin. It was concluded that, although insulin therapy must be adjusted to the individual, the diabetic cat usually requires twice-daily administration of isophane insulin; however, the protamine zinc insulin can be given once daily for satisfactory control. 相似文献

Blood glycosylated hemoglobin (GHb) concentration was quantified in 84 healthy cats, 9 cats with stress-induced hyperglycemia, 37 cats with newly diagnosed diabetes mellitus, and 122 diabetic cats treated with insulin or glipizide. Diabetic control was classified as good or poor in insulin-treated or glipizide-treated cats based on review of history, physical examination findings, changes in body weight, and measurement of blood glucose concentrations. Blood GHb concentration was determined using an affinity chromatography assay. Mean blood GHb concentration was similar for healthy normoglycemic cats and cats with transient, stress-induced hyperglycemia, but was significantly (P < .001) higher in untreated diabetic cats when compared with healthy normoglycemic cats. Mean blood GHb concentration was significantly (P < .001) higher in 84 cats with poorly controlled diabetes mellitus when compared with 38 cats in which the disease was well controlled. Mean blood GHb concentration decreased significantly (P < .01) in 6 cats with untreated diabetes mellitus after insulin and dietary treatment. A similar significant (P < .01) decrease in mean blood GHb concentration occurred in 7 cats with poorly controlled diabetes mellitus after diabetic control was improved by an increase in insulin dosage from 1.1 ± 0.9 to 1.4 ± 0.6 U/kg/ 24 h and by feeding a diet containing increased fiber content and in 6 cats with transient diabetes mellitus 8.2 ± 0.6 weeks after discontinuing insulin treatment. There was a significant (P< .01) stress-induced increase in mean fasting blood glucose concentration and mean blood glucose concentration for 12 hours after administration of insulin or glipizide but no change in mean blood GHb concentration in 5 docile diabetic cats 12.2 ± 0.4 weeks after the cats became fractious as a result of frequent hospitalizations and blood samplings. Results of this study suggest that evaluation of blood GHb concentration may be a clinically useful tool for monitoring glycemic control of diabetes in cats. 相似文献

It was investigated if IGF-1 levels in cats which experience diabetic remission (i.e. transient diabetes mellitus) differ from those in cats with permanent disease. Thirteen of 32 diabetic cats showed remission within 16 weeks after initiating insulin therapy, 19 cats continued to need insulin therapy. IGF-1 concentrations were measured before (t(0)), 1-3 (t(1)) and 4-8 (t(2)) weeks after initiating insulin therapy. No difference in IGF-1 levels was found between cats with transient and permanent diabetes at any point in time. In both groups of cats IGF-1 concentrations were significantly lower compared to those of controls before insulin administration. After starting insulin therapy IGF-1 increased significantly in both groups. In cats with transient diabetes IGF-1 levels were not different from controls already at t(1), whereas in cats with permanent diabetes it took until t(2). Although IGF-1 levels seem to normalize faster in cats with transient diabetes mellitus, measurement is not helpful to predict the course of the disease. 相似文献

CASE SUMMARIES: Two cases of diabetes mellitus occurring in bitches in association with pregnancy are reported. In the first case, a bitch with suspected acromegaly developed diabetes mellitus within 2 weeks of the due date. Despite insulin therapy, euglycaemia was not achieved. Tw o live, small pups were delivered by elective Caesarean section but died within 2 days. Signs consistent with acromegaly resolved but diabetes mellitus was permanent in the bitch. In the second case, diabetic ketosis with severe gastrointestinal disease was diagnosed 2 days after Caesarean section was performed due to dystocia. The pups delivered all died within 5 days. The bitch recovered fully from diabetes mellitus within 2 weeks and has remained euglycaemic without insulin for a period of at least 18 months. CLINICAL RELEVANCE: These two cases demonstrate that diabetes mellitus can occur in association with pregnancy in dogs, that diabetic ketosis can occur during transient diabetes mellitus in dogs, and suggest that acromegaly may occur during pregnancy-related dioestrus in dogs. The scarcity of previous reports of this nature, however, suggests that such cases are unusual. Lack of prompt resolution of hyperglycaemia may result in secondary diabetes mellitus becoming permanent. Management should focus on immediate insulin therapy or ovariohysterectomy to minimise this risk. Even mild hyperglycaemia should not be ignored during pregnancy. The insulin antagonistic effects of pregnancy, stressful illness, surgery and dystocia can be enough to result in diabetic ketosis in the absence of permanent insulin deficiency. Maternal hyperglycaemia may contribute to adverse fetal outcomes in dogs but further study is required regarding the nature of the risk. 相似文献

A case of diabetes mellitus in a cat is described, associated with prolonged administration of megestrol acetate for miliary dermatitis. The cat was presented with blindness due to diabetic retinopathy. Following the diagnosis, megestrol acetate was withdrawn. The diabetes proved to be transient and resolved after insulin therapy; however, severe visual impairment remained. The mechanism by which megestrol acetate induces diabetes is discussed. 相似文献

Five adult Samoyed dogs from two unrelated litters were diagnosed with diabetes mellitus. Two full-sibling male dogs (Family A) were raised in the same household. The other three dogs, two female and one male, were also full siblings (Family B) raised in different households. All five dogs developed polyuria and polydipsia and demonstrated fasting hyperglycemia and glucosuria. Diabetes mellitus was diagnosed in all five dogs and responded to appropriate therapy with insulin. The occurrence of insulin-dependent diabetes mellitus in multiple, closely related Samoyed dogs suggests a familial predisposition in this breed. 相似文献

CASE DESCRIPTION: A 21-year-old neutered male captive California sea lion developed chronic polyuria; polydipsia; polyphagia; accelerated development of existing cataracts; and frequent episodes of gastrointestinal upset including anorexia, signs of abdominal discomfort, diarrhea, and vomiting. CLINICAL FINDINGS: Chronic hypercholesterolemia, hypertriglyceridemia, hyperglycemia, and glucosuria were identified. During episodes of gastrointestinal abnormalities, transient hyperbilirubinemia and increased serum J-glutamyltransferase activities developed. Clinical findings strongly suggested chronic pancreatitis with secondary diabetes mellitus and intermittent cholestasis. Multiple diagnostic tests, including abdominal ultrasonography, serial hematologic and serum biochemical analyses, fecal examinations, urinalyses and bacteriologic culture of urine, measurement of serum fructosamine and insulin concentrations, and evaluation of thyroid and adrenal function, did not reveal any specific parasitic, endocrine, hepatic, or neoplastic etiologies. TREATMENT AND OUTCOME: For 1.5 years, the sea lion received once-daily administration of glargine insulin, gastrointestinal protectants, and a strict high-protein, low-fat diet. Daily monitoring of glucose regulation was achieved by training the sea lion to submit to blood and urine sampling. Glucose regulation ranged from fair to good, and clinical signs of diabetes mellitus lessened. Episodes of gastrointestinal upset still occurred, although the frequency and severity decreased. Ultimately, a severe episode developed, associated with diabetic ketoacidosis and sepsis, and the sea lion died. Severe fibrosing pancreatitis with exocrine and endocrine atrophy and abscesses arising from ectatic pancreatic ducts were found. Peripancreatic fibrosis caused stricture of the common bile duct, resulting in gallbladder distension without cholecystitis. CLINICAL RELEVANCE: Diabetes mellitus can occur secondary to chronic pancreatitis in California sea lions and insulin therapy should be considered. 相似文献

A propionate tolerance test (PTT) was used to determine the pathophysiology of a Japanese Black steer with hyperglycemia. In the hyperglycemic steer, a low insulin secretion was confirmed by a glucose tolerance test (GTT), so that the hyperglycemic steer was diagnosed as insulin-dependent diabetes mellitus. Although the plasma insulin concentration in the control cattle increased in response to propionate stimulation, a low insulin response to PTT was observed in the diabetic steer. The fact that both PTT and GTT determined that the diabetic steer had low insulin secretion suggests that the PTT might be an effective diagnostic tool for diabetes mellitus in cattle. 相似文献

A Warmblood foal was admitted at one day of age because of prematurity and seizures. Clinical and clinical pathology abnormalities were consistent with prematurity and suspected hypoxic seizures that responded to anti‐convulsive therapy. The foal stabilised after several days of intensive care but then developed an airway infection. Thoracic radiographs showed multiple cavitary lesions and ultrasound examination suggested intra‐cavital haemorrhage. The foal went on to develop septicaemia and was subjected to euthanasia. Post mortem examination revealed multiple bullous emphysema with haemorrhage. This disorder should be considered in the differential diagnosis of foals having air‐fluid filled cavities on thoracic radiographs. 相似文献

Dogs do not appear to progress from obesity-induced insulin resistance to type 2 diabetes mellitus. Both postprandial hyperglycemia and postprandial hypertriglyceridemia have been proposed to cause or maintain beta cell failure and progression to type 2 diabetes mellitus in other species. Postprandial glucose, triglyceride, and insulin concentrations have not been compared in lean and obese dogs. We measured serum glucose, triglyceride, and insulin concentrations in nine naturally occurring obese and nine age- and gender-matched lean dogs. After a 24-h fast, dogs were fed half their calculated daily energy requirement of a standardized diet that provided 37% and 40% of metabolizable energy as carbohydrate and fat, respectively. Fasting and postprandial glucose and triglyceride concentrations were greater in the obese dogs (P < 0.001), although the mean insulin concentration for this group was five times greater than that of the lean group (P < 0.001). Most of the 0.6 mM (11 mg/dL) difference in mean postprandial glucose concentrations between lean and obese dogs was attributable to a subset of persistently hyperglycemic obese dogs with mean postprandial glucose concentrations 1.0 mM (18 mg/dL) greater than that in lean dogs. Persistently hyperglycemic obese dogs had lower triglyceride (P = 0.02 to 0.04) and insulin (P < 0.02) concentrations than other obese dogs. None of the dogs developed clinical signs of diabetes mellitus during follow-up for a median of 2.6 yr. We conclude that pancreatic beta cells in dogs are either not sensitive to toxicity because of mild hyperglycemia or lack another component of the pathophysiology of beta cell failure in type 2 diabetes mellitus. 相似文献

Dysphagia and milk regurgitation are relatively infrequently observed clinical signs in neonatal foals but, when present, can commonly arise from anatomic or functional disorders of the upper airway. Less commonly, milk regurgitation can be caused by anatomic or neuromuscular disorders of the oesophagus. In the report presented here, a neonatal foal was examined for milk regurgitation at 4 days of age and was diagnosed with transient oesophageal ectasia via oesophagoscopy and contrast radiography. Aspiration pneumonia was treated with broad-spectrum antimicrobials and the owner was instructed to intermittently elevate the forelimbs to facilitate passage of milk out of the dilated oesophagus. The milk regurgitation resolved and reassessment of the foal at 6 weeks of age documented the absence of oesophageal ectasia and resolution of aspiration pneumonia. The foal was reported to be healthy and consuming food normally 6 months after initial examination and was in good body condition. This case is unique in that the oesophageal ectasia improved with time; furthermore, other potential causes of dysphagia and milk regurgitation of oesophageal origin in neonatal foals are discussed. 相似文献

An 18-year-old Spanish Mustang mare was referred for evaluation of progressive weight loss and persistent hyperglycemia. Clinicopathologic abnormalities included marked hyperglycemia and glycosuria. Serum cortisol concentration was appropriately decreased following administration of dexamethasone, indicating that the horse did not have pituitary pars intermedia dysfunction. Serum insulin and plasma C-peptide concentrations were low, suggesting that hyperglycemia was a result of decreased secretion of insulin by pancreatic beta cells. In addition, glucose concentration did not return to the baseline concentration until 5 hours after i.v. administration of a glucose bolus, suggesting that insulin secretion, insulin effect, or both were reduced. However, i.v. administration of insulin caused only a slight decrease in the plasma glucose concentration, giving the impression that the action of insulin was impaired. Within 5 hours after administration of a combination of glyburide and metformin, which is used to treat diabetes mellitus in humans, the glucose concentration was within reference limits. The horse was euthanized, and a postmortem examination was done. Immunohistochemical staining of sections of the pancreas revealed attenuation of the pancreatic islet beta-cell population, with beta cells that remained generally limited to the periphery of the islets. These findings indicate that, albeit rare, pancreatic beta-cell failure may contribute to the development of diabetes mellitus in horses. 相似文献

This case report describes ivermectin‐induced blindness in a dog and a foal with normal ophthalmic fundic examinations and attenuated electroretinography (ERG). Subsequent recovery in ERG was noted following intravenous lipid emulsion (ILE) therapy. A dog and a foal were evaluated for ivermectin‐induced blindness. Clinical signs included dull mentation, absent pupillary light reflexes (PLRs), and absent menace on presentation. The animals had normal fundoscopic examinations; however, in both cases ERG was consistent with neurosensory retinal dysfunction. Following ILE therapy for ivermectin toxicosis, return of menace, PLRs, and normal mentation were noted, as was improvement in ERG and serum ivermectin levels. These are the first documented cases of ivermectin‐induced blindness in a dog and a foal with normal fundic examinations and attenuated ERG. ERG improved in both animals after ILE therapy. ERG may assist in the diagnosis of ivermectin toxicosis in dogs and horses. ILE therapy may hasten recovery in treatment of ivermectin‐induced blindness. 相似文献

Although metabolic disorders are a frequent concern in cattle, they are not commonly recognized in bulls. The combination of hyperglycemia, acetonemia, ketonuria, and glycosuria in a bull was highly suggestive of diabetes mellitus. This uncommon diagnosis was confirmed by results of intravenous glucose tolerance testing. Results of the test and serum insulin values were further able to classify the disease in this bull as type-I diabetes mellitus. 相似文献

OBJECTIVE: To evaluate glycemic response to insulin treatment in dogs with diabetes mellitus. DESIGN: Retrospective study. ANIMALS: 221 dogs with diabetes mellitus. PROCEDURE: Type and dosage of insulin used, minimum and maximum blood glucose concentrations, time of blood glucose concentration nadir, and optimal duration of action of insulin were determined on the basis of data obtained prior to initial examination at the teaching hospital (127 dogs), at the time of initial examination (212 dogs), at the time a second follow-up blood glucose curve was performed (59 dogs), and at the time of clinical control of diabetes mellitus (83 dogs). RESULTS: Prior to examination, 69 of 127 dogs (54%) received 1 s.c. insulin injection daily. Thirty-one dogs (24%) received a high dose of insulin (i.e., > 1.5 U/kg [0.7 U/lb] of body weight); 27 of these dogs (87%) received 1 injection/d. Eleven of 16 dogs (69%) that were hypoglycemic (blood glucose concentration < 80 mg/dl) also received 1 injection/d. However, optimal duration of action of insulin was > 12 hours in only 5 of 83 dogs (6%) evaluated at the time diabetes mellitus was clinically controlled. At that time, only 1 dog (1%) received a high dose of insulin, and the dog received 2 injections/d. Moreover, 8 of 10 dogs (80%) with hypoglycemia received 1 injection/d. CONCLUSIONS AND CLINICAL RELEVANCE: Most dogs with diabetes mellitus are clinically regulated with 2 daily insulin injections. Administration of a high dose of insulin or development of hypoglycemia may be more common in diabetic dogs that receive insulin once daily, compared with dogs that receive insulin twice daily. 相似文献
