This study examines the association of pre-surgical clinical parameters in cows with left displacement of the abomasum (LDA) with the probability of cure. Data from 466 cases of LDA in which omentopexy was performed were analysed. Cows were classified in three categories according to the outcome of treatment. Cows in the first category were cured, i.e. sent back to the farm for further milk production. Cows in the second category were sent for slaughter because of an unfavourable prognosis concerning productivity. Cows in the third category either died or were salvaged because of poor prognosis concerning survival. Factors were examined for their possible influence on the outcome of treatment by comparing the values of successfully treated cows to those cows that either died or had to be sent for slaughter. Factors that were associated with a favourable prognosis were a short duration of disease, an undisturbed general condition, good appetite, normal faeces, a higher body weight, lower haematocrit, haemoglobin and erythrocyte counts, lower urea, AST and bilirubin, and higher sodium, potassium and chloride concentrations compared with cows with an unfavourable prognosis. Haemoconcentration was associated with higher AST, bilirubin and urea and with low sodium, potassium and chloride. Acetonuria was associated with increased AST and bilirubin and low urea. Low sodium and potassium concentrations were associated with an impaired general condition. It is concluded that a thorough clinical examination with special emphasis on general condition, liver function and dehydration status is of great importance in determining the prognosis of abdominal surgery in cows with LDA.

An outbreak of footrot occurred in a flock of Corriedale sheep; 27 animals were treated with antibiotic and footbathed in a 5% copper sulfate solution. Being deprived of water for > 17 h, many sheep drank the footbath solution. After 6 h 16 sheep became ill with acute copper poisoning, 10 animals died within 10 h; 6 were severely ill and were sent to Veterinary Hospital, and 4 had mild signs and recovered without treatment. The sick sheep had anorexia, dullness, grinding teeth, moaning, rumen atony, dehydration, dark blue-green diarrheic feces and congested membranes. They were treated with 3.4 mg tetrathiomolybdate/kg body weight and lactated Ringer's solution iv, oral molybdate, sulfate, kaolin and pectin, and drenched with antacids. Two of the 6 sheep died during hospitalization. The ingestion of copper solution caused an intense gastrointestinal injury that resulted in ulcers, petechial and echymotic hemorrhages in the mucosa, mild hemolysis detected by microscopic hemoglobinuria and a lowered packed cell volume, severe hepatic injury that raised the AST and gammaGT blood values, and moderate kidney lesions with increasing serum blood urea and nitrogen creatinine levels.

We report on a DAX1 gene investigation in a patient with X-linked adrenal hypoplasia congenita (AHC) and hypogonadotropic hypogonadism (HH) in order to identify mutations causing this disorder and to confirm the clinical diagnosis. The description of the clinical course of the condition with a detailed documentation of longitudinal data is also reported. A male newborn was referred at 45 days of life because of vomiting, dehydration, and weight loss. The diagnosis was primary adrenal insufficiency. The appropriateness of glucocorticoid therapy during the prepubertal period was difficult to judge because of elevated ACTH levels on one hand and progressive retardation of bone age on the other hand. Basal and GnRH stimulated gonadotropin levels remained low during the entire period of examination and exogenous gonadotropin treatment was begun. This had to be interrupted at age 14.6 years because of the occurrence of a 3rd degree anaplastic ependimoma of the left posterior-parietal region, without apparent lepto-meningeal involvement. The molecular analysis of DAX1 gene of the propositus showed deletion of nucleotides AAT in exon 2, resulting in the loss of the Asn430. No alterations were found in the mother and grandmother. This deleted residue lies in one of the helices forming the hydrophobic core of the ligand-binding domain (LBD); thus this mutation may be the cause of the observed phenotype. Further investigations are needed to verify its causal role in AHC associated with HH.

There are few extensive studies about clinicopathological findings of spontaneous canine babesiosis caused by a large form of the parasite found in Europe. To further characterize and describe clinicopathological findings in dogs affected with this large form of Babesia in northeastern Italy, we evaluated 23 Italian dogs with canine babesiosis by means of clinical history, physical examination, hematological, biochemical, hemostatic tests, serum electrophoresis and urinalysis. Seventeen dogs (74%) had recently traveled on a hunting trip (within 5-15 days of being presented to the clinic) to Bosnia and Herzegovina (n=7), to Croatia (n=8) and to Hungary (n=2). The duration of clinical signs ranged from 1 to 5 days prior to the arrival at the clinic. The main clinical signs were dehydration (100%), apathy (74%), anorexia or decrease appetite (70%) and fever (68%). The anemia was present in 74% of the dogs and classified as mild (35%), moderate (59%) and severe (6%). In all cases, the anemia was normocytic and normochromic. Only three dogs presented erythrocyte regeneration. Seventy percent of dogs had hemolytic anemia and 30% had non-hemolytic anemia. Sixty-nine percent of dogs showed leucopenia and 74% neutropenia. Leucocitosis, due to mature neutrophilia and lymphocytosis, was present in one dog. Activated lymphocytes were noted in 61% of dogs. In all dogs, thrombocytopenia and an elevated hyperfibrinogenemia were present. Significant prolonged activated partial thromboplastin time (aPTT) was only found in one case. In four dogs, both plasma fibrinogen/fibrin degradation products (FDPs) and D-Dimer were increased. Antithrombin (AT) was slightly decreased in 11 of the 23 dogs. In the majority of cases, mild elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinekinase (CK), total bilirubin and lactic acid and decrease of total iron and total iron binding capacity (TIBC) were present. In conclusion, the main clinicopathological findings were a mild to severe thrombocytopenia, a mild to moderate hemolytic anemia, neutropenia and hyperfibrinogenemia.

The present study reports the seasonal and physiological variations of copper, zinc, magnesium, iron, sodium chlorine, potassium, calcium, phosphorus, urea, alkaline phosphatase (ALP), creatinine (CR), aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholesterol, albumin, globulin, lactate dehydrogenase (LDH), and total protein concentrations in cattle. Two groups of mated (n = 14) and nonmated (n = 10) healthy cows were selected for the study. Serum samples were collected at each of four periods: (1) early pregnancy (May), (2) midpregnancy (August), (3) late pregnancy (October), and (4) lactation (February). Physiological variations result in changes of cholesterol, calcium, LDH, and total protein concentrations. Phosphorus varies only with seasonal but not physiological changes, whereas ALP, copper, magnesium, and potassium concentrations change with physiological and seasonal conditions. The copper concentration is increased through the pregnancy. Neither the seasonal nor the physiologic variations affect zinc, iron, sodium, chlorine, calcium, urea, creatinine, albumin, and globulin values in both groups in all periods. Thus, these values can be used as reference for both mated and nonmated bovines. The measured total protein might not reflect its true value because of dehydration during the hot season. These observations suggest that seasonal and physiologic variations have to be taken into consideration for the correct interpretation of serum chemistry and elements status in cattle. Nutritional supplements are required for cattle during certain periods to avoid a decline of their performance, which would then represent consequent economic loses.

The clinical findings and treatment of 94 cattle with listeriosis are described. The general behaviour and condition of the animals were mostly moderately to severely disturbed. A common abnormality in posture was an exaggerated forward or sideward stance, and 11 of the animals were recumbent. More than half of the animals were ataxic and 22 circled. The most frequent cranial neurological signs observed were facial nerve paralysis, salivation, strabismus, reduced or absent pupillary light reflex, reduced or absent tongue movement and head tilt. The haematological and biochemical findings did not contribute to the diagnosis of listeriosis, but they were useful indicators of dehydration and the acid-base status of the animal. Forty-four of 57 of the animals had high leucocyte counts in the cerebrospinal fluid (CSF), mostly mononuclear cells. Eighty-seven of the animals were treated with various antibiotics (penicillin G, oxytetracycline, amoxicillin, and amoxicillin and gentamicin combined), but there was no significant difference in the success rate of the different treatments. Only two of the nine recumbent animals that were treated survived. Univariable analysis suggested that animals that were recumbent, excited, with an absent or weak menace reflex, nystagmus, high numbers of leucocytes in the CSF, high serum concentrations of urea and calcium and high serum activities of aspartate aminotransferase and creatine kinase, and an acid-base deficit, had a smaller chance of surviving. When a logistic regression model was constructed, only recumbency, excitement and a weak or absent menace reflex remained significant factors affecting the likelihood of survival.

A 74-year-old man with depressive symptoms was admitted to a psychiatric hospital due to insomnia, loss of appetite, exhaustion, and agitation. Medical treatment was initiated at a daily dose of 20 mg paroxetine and 1.2 mg alprazolam. On the 10th day of paroxetine and alprazolam treatment, the patient exhibited marked psychomotor retardation, disorientation, and severe muscle rigidity with tremors. The patient had a fever (38.2 degrees C), fluctuating blood pressure (between 165/90 and 130/70 mg mm Hg), and severe extrapyramidal symptoms. Laboratory tests showed an elevation of creatine phosphokinase (2218 IU/L), aspartate aminotransferase (134 IU/L), alanine aminotransferase (78 IU/L), and BUN (27.9 mg/ml) levels. The patient received bromocriptine and diazepam to treat his symptoms. 7 days later, the fever disappeared and the patient's serum CPK levels were normalized (175 IU/L). This patient presented with symptoms of neuroleptic malignant syndrome (NMS), thus demonstrating that NMS-like symptoms can occur after combined paroxetine and alprazolam treatment. The adverse drug reaction score obtained by the Naranjo algorithm was 6 in our case, indicating a probable relationship between the patient's NMS-like adverse symptoms and the combined treatment used in this case. The involvement of physiologic and environmental aspects specific to this patient was suspected. Several risk factors for NMS should be noted in elderly depressive patients whose symptoms often include dehydration, agitation, malnutrition, and exhaustion. Careful therapeutic intervention is necessary in cases involving elderly patients who suffer from depression.

Data were gathered from the records of 51 children of median age 1.5 years who survived more than 6 months after intestinal transplantation. Abnormal liver function tests (LFTs) were defined as serum aspartate aminotransferase (AST) greater than 100 IU/L or total bilirubin greater than 2.0 g/dL lasting more than 3 days. Temporary elevation was defined when LFTs returned to normal without graft loss or death. LFT elevation at the time of transplantation was not included as a temporary LFT elevation. Median follow-up was 36 months. In multivisceral transplant recipients, all patients (n = 34) showed abnormal LFTs at transplantation that normalized within a median period of 2 days. Temporary LFT elevations were seen in 20 of 34 (59%) in multivisceral transplantation and 5 of 17 (29%) in isolated intestinal transplantation. Median length of elevation was 14 days in multivisceral transplantation and 12 days in isolated intestinal transplantation. Peak AST was 353 +/- 190 IU/dL in multivisceral transplantation and 839 +/- 605 IU/dL in isolated intestinal transplantation (P = .0059). Events associated with temporary LFT elevations in multivisceral transplantation were total parental nutrition (TPN) (n = 8), dehydration (n = 2), viral infection (n = 2), others (n = 3), and nonspecific (n = 5). Events in isolated intestinal transplantation were posttransplant lymphoproliferative disorder (n = 2), TPN (n = 1), and nonspecific (n = 2). Temporary LFT elevations were commonly seen among pediatric intestinal recipients, which correlated with events other than rejection. Approximately half of the temporary LFT elevations were associated with no significant clinical events. They resolved spontaneously. Interestingly, the peak AST value was higher in isolated intestinal transplantation compared to multivisceral transplantation.

This paper describes clinical, laboratory and pathological findings of sheep, which is intoxicated with castor bean. The source of intoxication was a miscellaneous garden waste. Forty-five animals showed clinical toxicosis and 17 died. The clinical signs included weakness, salivation, profuse watery diarrhoea, dehydration, mydriasis, teeth grinding, hypothermia and recumbency. The most significant haematological and biochemical findings were a high haematocrit, high concentration of serum BUN, creatinine and phosphorus and high activity of serum CK and AST. Pathology revealed severe gastroenteritis, cardiac haemorrhage and necrosis, hepatic necrosis and acute tubular necrosis in kidneys. Treatment included symptomatic and supportive care with fluid therapy and cathartic administration.

A 6-year-old spayed female domestic shorthair cat with a 3-week history of inappetence, weight loss, and hiding was examined. A palpable abdominal fluid wave, dehydration, and a small tear on the left flank were noted during initial examination. When the cat was gently restrained for blood sampling, the skin on the dorsal neck tore, leaving a 15 cm x 7 cm flap of skin. Clinicopathological abnormalities included nonregenerative anaemia, hypoalbuminaemia, increased globulin concentration, and mildly elevated aspartate aminotransferase and alkaline phosphatase activities. Abdominal fluid was viscous and had a total protein of 5.3 g dL(-1) with 316 cells microL(-1), consistent with a modified transudate. Cytology of the abdominal fluid revealed 86% nondegenerate neutrophils, 13% macrophages, and 1% small lymphocytes. Histopathological evaluation and indirect immunohistochemistry confirmed a diagnosis of feline infectious peritonitis, hepatic lipidosis and feline skin fragility syndrome. Feline skin fragility syndrome has not previously been reported in association with feline infectious peritonitis (FIP). Its inclusion as a clinical sign associated with FIP may facilitate a diagnosis.
