Comparative evaluation of biochemical parameters during urinary infection in Maltese and Belgian shepherd dogs

Urinary tract infections can be uncomfortable, painful and even dangerous for most dog breeds. Clinical signs are often nonspecific and insufficient for diagnosis. Urinalysis in combination with biochemical parameters and urine culture is the best combination of clinical findings for diagnosis of urinary tract infections. The incidence of urinary tract infections in dogs population is growing and 27% of dogs develop an urinary tract infection through their life. Urinary infections occur more often in the elderly than in younger dogs. More than 70% of all urinary tract infections are infections with one bacterial species. Biochemical profile is important aspect for diagnosis establishment, but due to the nature of action infection by different agents may be considered as individual case. The main aim of this research was to analyse biochemical parameters of Maltese and Belgian Shepherd (Malinois) dog breed, who were affected by urinary tract infections. Urea concentration was elevated in Malinois, while urea, phosphates, albumins and alkaline phosphatase activity were elevated in Maltese dogs. Statistical analysis showed differences in concentrations of urea, creatinine, phosphates, so as alanine aminotransferase, alkaline phosphatase and amylase activity between compared breeds during acute urinary infections. Maltese dogs are less resistant to bacterias, that causes urinary tract infections, and have lower chance to maintain homeostasis of biochemical parameters in blood during urinary bacterial infections, in comparison to Maltese dogs

Effects of trivalent and hexavalent dietary chromium on blood biochemical profile in Japanese quails

Trivalent chromium is an essential trace element for humans and animals and it is the final product of hexavalent chromium reduction in the cell. It is an integral part of the glucose-tolerance factor, which increases the systemic impact of insulin. The aim of this study was to analyse the effect of trivalent and hexavalent chromium on selected biochemical parameters in Japanese quails. Birds were divided into three groups: group I (control group, n=12), group II (treated with trivalent chromium, n=12) and group III (treated with hexavalent chromium, n=12). During 20 days of follow-up, control and ex-perimental groups of quails had identical diet; chromium was added daily into the food (5 mg/kg) and water (5 mg/L) of the experimental groups. Glucose concentrations were the highest in Group III, while lowest glucose concentrations were obtained in Group I. There were higher differencies regar¬ding blood biochemical parameters between control group and quails treated with Cr(VI). Our results showed that hexavalent chromium had negative effects on biochemical parameters in quails, while treatment with Cr(III) showed minor fluctuations in concentrations or activities of blood biochemical parameters

Hamartomas, teratomas and teratocarcinosarcomas of the head and neck: Report of 3 new cases with clinico-pathologic correlation, cytogenetic analysis, and review of the literature

<p>Abstract</p> <p>Background</p> <p>Germ-cell tumors (GCT) are a histologically and biologically diverse group of neoplasms which primarily occur in the gonads but also develop at different extragonadal sites in the midline of the body. The head and neck region including the upper respiratory tract is a very rare location for such tumors in both children and adults, which can cause diagnostic and therapeutic difficulties.</p> <p>Methods</p> <p>We describe here two new cases of multilineage tumors including sinonasal teratocarcinosarcoma [SNTCS], and congenital oronasopharyngeal teratoma (epignathus) and compare their features with those of a new case of a rare salivary gland anlage tumor [SGAT], an entity for which the pathogenesis is unclear (i.e. hamartoma versus neoplasm). We correlate their presenting clinico-pathological features and compare histologic and cytogenetic features in an attempt to elucidate their pathogenesis and biologic potentials.</p> <p>Results and discussion</p> <p>Cytogenetic analysis revealed chromosomal abnormalities only in the case of SNTCS that showed trisomy 12 and 1p deletion. Both cytogenetic abnormalities are characteristically present in malignant germ cell tumors providing for the first time evidence that this rare tumor type indeed might represent a variant of a germ cell neoplasm. The SGAT and epignathus carried no such cytogenetic abnormalities, in keeping with their limited and benign biologic potential.</p> <p>Conclusion</p> <p>The comparison of these three cases should serve to emphasize the diversity of multilineage tumors (hamartomas and GCT) of the upper respiratory tract in regards to their biology, age of presentation and clinical outcomes. Malignant tumors of germ cell origins are more likely to affect adults with insidious symptom development, while benign tumors can nevertheless cause dramatic clinical symptoms which, under certain circumstances, can be fatal.</p

Intraoperative transfusion practices in Europe

BACKGROUND: Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe factors determining transfusion throughout Europe. METHODS: We did a prospective observational cohort study enrolling 5803 patients in 126 European centres that received at least one pRBC unit intraoperatively, during a continuous three month period in 2013. RESULTS: The overall intraoperative transfusion rate was 1.8%; 59% of transfusions were at least partially initiated as a result of a physiological transfusion trigger- mostly because of hypotension (55.4%) and/or tachycardia (30.7%). Haemoglobin (Hb)- based transfusion trigger alone initiated only 8.5% of transfusions. The Hb concentration [mean (sd)] just before transfusion was 8.1 (1.7) g dl(-1) and increased to 9.8 (1.8) g dl(-1) after transfusion. The mean number of intraoperatively transfused pRBC units was 2.5 (2.7) units (median 2). CONCLUSION: Although European Society of Anaesthesiology transfusion guidelines are moderately implemented in Europe with respect to Hb threshold for transfusion (7-9 g dl(-1)), there is still an urgent need for further educational efforts that focus on the number of pRBC units to be transfused at this threshold. CLINICAL TRIAL REGISTRATION: NCT 01604083
