Abstract Objective Chemical restraint in dairy calves is necessary to enable diagnostic and surgical procedures. It is unclear whether xylazine or detomidine differ with regard to desirable and unwanted effects. Material and methods In a prospective randomized interventional study, 10 healthy Holstein-Friesian calves (age range 3–6 month) were sedated with either xylazine (0.1 mg/kg, Group X, n = 5) or detomidine (0.03 mg/kg, Group D, n = 5) intravenously, followed by butorphanol (0.1 mg/kg i. v.) in all animals. Characteristics of sedation and selected pharmacodynamic parameters were compared between groups using a non-parametric Mann-Whitney U test. Results All calves (5/5) in Group X and (3/5) calves in Group D became laterally recumbent within 5 minutes. Two calves (40 %) in Group D remained standing and could not been positioned in lateral recumbency 15 minutes after initial administration of the sedation agents. Sedation scores, onset and duration of sedation did not differ between groups. Heart and respiratory rate decreased in both groups. Mean arterial pressure was with around 30 mmHg significantly higher in Group D (t25, t30, t35, t40 with p = 0.018, 0.036, 0.029 and 0.016, respectively). In Group X, glucose level (t60) and packed cell volume (t30) were significantly lower (p = 0.032 and 0.048, respectively). Conclusion and clinical relevance The xylazine-butorphanol combination provided reliable recumbent chemical restraint. With detomidine-butorphanol recumbency failed in some individuals, but a sufficient clinical sedation was achieved. Based on the limited monitoring used in this study, the side effects are of minor clinical relevance in healthy individuals.

Platelet and leukocyte count reference intervals (RIs) for cattle differ by age and while adult RIs are known, RIs for calves are studied less. The aims of this observational study are to evaluate variation of platelet counts of Holstein Friesian calves over the first 14 days of life and to propose RIs for platelet and leukocyte counts of Holstein Friesian calves aged 0–60 days. In a longitudinal study, 19 calves were blood sampled 17 times, in the first 14 days of their lives. Blood was collected in a citrate blood tube and platelet counts were determined. We assessed the course of platelet counts. In a field study, 457 healthy calves were blood sampled once. Blood was collected in an EDTA blood tube and platelet and leukocyte counts were determined. The RIs were calculated by the 2.5 and 97.5 percentiles. Platelet counts started to increase 24 h after birth (mean platelet count 381 × 109/L ± 138 × 109/L) and stabilized after five days (mean platelet count 642 × 109/L ± 265 × 109/L). In calves up to six days of age, platelet counts were lower than in calves older than five days. In conclusion, the RIs of platelet and leukocyte counts in calves were wider in range than the RIs for adult cattle, therefore, calf specific RIs for platelet and leukocyte counts should be used. From 6 until 60 days of age, we propose an RI for platelet counts of 287–1372 × 109/L and for the first 60 days of life an RI for leukocyte counts of 4.0–18.9 × 109/L.

Objectives. To discuss the characteristics of the amount of urinary total antioxidants in tumor diseases and the possibility of utilizing the changing regulation of urinary antioxidants to diagnose tumor diseases.Method. Urine and serum specimens from 130 healthy people were used to investigate the variation of antioxidant capacity against age. Urine and serum specimens from 44 unselected patients with tumors and 44 healthy people with same age background were used to explore the significance of urinary antioxidant capacity in clinic to diagnose tumor diseases. Potassium permanganate agar method and iodine starch method were used to determine the amount of total antioxidants.Results. In healthy people, more antioxidants in urine were measured in older people, while the results were opposite in serum. More antioxidants were found in urine of tumor patients than in healthy people with same age-range.Conclusions. According to the results of 130 measurements, the amount of antioxidants in urine varies by age. By using agar methods to measure antioxidants, the effect of age is required to be considered. Antioxidants levels from tumor patients were significantly higher than healthy individuals in urine. The combination of urine and serum to determine total antioxidants can better diagnose tumor diseases based on iodine starch method, with area under the receiver operating characteristics curve at 0.787.

Objectives: The objective of the study was to compare the outcome of Classical Dacrocystorhinostomy(DCR) alone or with Slicon intubation in patients of primary nasolacrimal duct obstruction.Study design: This is a randomized prospective interventional study performed at Saidu Teaching Hospitalform from 1st January'2006 to 31st December 2006.Material and methods: Diagnosis of nasolacrimal duct obstruction was made on basis of history, clinicalexamination, regurgitation test and syringing of the nasolacrimal passage. Patients were selected byconvenient sampling and were randomized to two groups, for DCR with and without Silicon tube. Silicontube was removed after 4 months of surgery. Patients were followed up to 6 months.Results: Total number of patients was one hundred. Fifty (50%) patients were operated with siliconintubation and 50 (50%) without silicon intubation. Male to female ratio was 1:1.27.Age range was 15 yearsto 80 years. Mean, median and mode ages were 42.54, 47 and 30 years respectively. Eleven patients werelost from the study at various stages and were not included in the results of the study. The complicationsnoted were silicon tube loss in 2 cases, silicon tube displacement in 3 cases and DCR failure in 4 cases.Among the failure, 2 cases belonged to each group with and without silicon intubation.Conclusions: We conclude that the complications rate with and without silicon intubation is the same inprimary nasolacrimal duct obstruction. It is therefore, recommended that silicon intubation may not benecessary in such cases.Key words: DCR, Intubation, NLD Obstruction.

Background Sedation for magnetic resonance imaging mandates deep sedation to ensure patient immobility. The nebulised route of drug delivery carries the advantage of good bioavailability and safety profile. We aimed to compare the efficacy and safety of nebulised dexmedetomidine and ketamine for sedation in children undergoing magnetic resonance imaging. Methods A total of 71 children, aged two to eight years scheduled for outpatient magnetic resonance imaging were randomly allocated to receive nebulised dexmedetomidine 2 μg/kg (group D) or nebulised ketamine 2 mg/kg (group K) 30min before magnetic resonance imaging. Results Nebulised dexmedetomidine (2 μg/kg) resulted in faster onset and significantly better sedation scores with rapid clear-headed recovery. Ketamine resulted in better venepuncture scores but was associated with more neuropsychological events at recovery. Conclusion Nebulised dexmedetomidine at 2 μg/kg provides rapid onset of satisfactory sedation, with good parental separation and a quicker and more clear-headed recovery, allowing for a smooth magnetic resonance imaging experience.

The results of feeding experiments, involving a total of 117 Holstein-Friesian calves, were reported. No whole milk nor fresh skimmilk was fed to the calves after their second day of age. Milk substitutes containing 40 to 50 per cent dried skimmilk, 5 to 10 per cent emulsified, stabilized lard and at least 30 p.p.m. of Aureomycin (chlortetracycline) or Terramycin (oxytetracycline) in the dry matter permitted weight gains equal to, or exceeding, the Beltsville standards during the milk feeding period. Supplementary lecithin had no effect on performance of the calves. Weaning calves from milk substitutes at weights of 145 to 150 lb. was considered preferable to weaning at specified ages because of apparent differences in physiological development that exist among calves for the first few months of life.

AbstractThe objectives of this study were (i) to characterise clinical health in dairy calves on an Irish research farm during the artificial calf-rearing period and (ii) to determine whether calves’ pre-weaning intakes and feeding behaviour, recorded by electronic calf feeders, changes in response to incidents of bovine respiratory disease (BRD). Holstein-Friesian (H-F) and Jersey (J) calves were fed by automatic milk replacer (MR) and concentrate feeders. Feeding behaviour, including MR consumption, drinking speed, number of rewarded and unrewarded visits to the feeder as well as concentrate consumption, was recorded by the feeders. A modified version of the Wisconsin calf health scoring criteria chart was used to score calves’ clinical measurements and identify incidences of BRD. Thus, 40% of calves were found to have at least one incident of BRD. Feeding behaviour was altered during incidents of BRD. The number of unrewarded visits to the feeder was reduced, by approximately four visits, for calves with BRD during the 3 d prior to the identification of BRD(P< 0.05) and tended to be reduced during the 7 d following the identification of BRD(P= 0.05), compared with healthy calves. Additionally, calves with BRD had a tendency for reduced net energy intake (approximately 8%) during the 3 d prior to the identification of BRD, compared with healthy calves. Therefore, calf feeding behavioural data, recorded by electronic feeders during the pre-weaning period, can indicate cases of BRD.

Abstract BACKGROUND The European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) European Biological Variation Study (EuBIVAS) has been established to deliver rigorously determined biological variation (BV) indices. EuBIVAS determined BV for serum creatinine using the enzymatic and alkaline picrate measurement methods. METHOD In total, 91 healthy individuals (38 males, 53 females; age range, 21–69 years) were bled for 10 consecutive weeks at 6 European laboratories. An equivalent protocol was followed at each center. Sera were stored at −80 °C before analysis. Analyses for each patient were performed in duplicate within a single run on an ADVIA 2400 system (San Raffaele Hospital, Milan). The data were subjected to outlier and homogeneity analysis before performing CV-ANOVA to determine BV and analytical variation (CVA) estimates with confidence intervals (CI). RESULTS The within-subject BV estimates [CVI (95% CI)] were similar for enzymatic [4.4% (4.2–4.7)] and alkaline picrate [4.7% (4.4–4.9)] methods and lower than the estimate presently available online (CVI = 5.9%). No significant male/female BV differences were found. Significant differences were observed in mean creatinine values between men and women and between Turkish individuals and those of other nationalities. Between-subject BV (CVG) estimates, stratified accordingly, produced CVG values similar to historical BV data. CVA was 1.1% for the enzymatic and 4.4% for alkaline picrate methods, indicating that alkaline picrate methods fail to fulfill analytical performance specifications for imprecision (CVAPS). CONCLUSIONS The serum creatinine CVI obtained by EuBIVAS specifies a more stringent CVAPS than previously identified. The alkaline picrate method failed to meet this CVAPS, raising questions regarding its future use.

Background: Urinary tract infections (UTI) simply the symptomatic or asymptomatic colonization of the kidneys, ureters, urinary bladder or/and the urethra by microorganisms, commonly bacteria. When these infections affect the kidneys, it is known as pyelonephritis. Objectives: To calculate the percentile risk of medically inclined apparently healthy individuals acquiring urinary tract infection. Methods: Written consent was sought on every questionnaire. It was carried out within the period of August to November, 2018. The study was done with over 160 persons; 154 questionnaires were accepted as properly filled. The questionnaires were gender specific. Persons cut across doctors, nurses, laboratory scientists, nursing students and medical students. The sampling study used was single blinded method. Areas studied were Plateau state (Jos University Teaching Hospital, Plateau Specialist Hospital and school of Midwifery; Vom), Abuja (University of Abuja Medical College Campus) and Nasarawa state (Bingham University). Data was collected, tabulated and classified into mild, moderate and high risks. (males, N = 71 with an age range of 19 - 45 years; females, N = 83 with an age range of 19 - 44 years). Results: Assessment criteria male/female low risk 42 (59.2%)/10 (12.0%), moderate risk 23 (32.4%)/29 (34.9%) and high risk 6 (08.5%)/44 (53.0%). Conclusions: Hygiene is a crucial factor in predisposition to UTI. Women are at higher risk of acquiring urinary tract infections. Sickle cell may be a predisposing factor to pyelonephritis.

Dairy calves must be fed appropriately to meet their nutritional needs, supporting optimal growth and development to achieve the recommended target age at first calving (AFC) of 24 months. Traditional restricted milk feeding practices suppress growth, contribute to negative welfare states and may result in malnutrition and immunosuppression. In this study a total of eight high yielding calves (four Holstein Friesian and four Sahiwal breed) whose average body weight was 44.8 kg and 58 kg respectively. The supplied calf starter was composed of maize crushed, rice polish, wheat bran, gram broken, mustard oil cake, vitamin mineral premix, molasses and common salt. Calf starter was supplied initially 0.25 kg/day/calf in equal halves to the experimental calves twice a day i.e. at 7.00 AM and 12.30 PM and gradually increase upto 1 kg/d/calf. Average body weight gain, wither height gain, body length gain, barrel height gain, and hip height gain in Sahiwal and Holstein Friesian calves were 65.97±1.04 Kg, 31.04±1.13 inch, 32.34±1.46 inch, 12.80±0.71 inch, 35.05±1.27 inch, and 53.61±2.41 Kg, 29.78±1.17 inch, 30.93±1.66 inch 11.78±0.66 inch, 33.44±1.41 inch respectively. Our study concluded to establish a consensus on calf feeding standards which support physiological function, facilitate weaning, support growth targets and ensure calf health and welfare is protected.
