Statistical Reflections Regarding the Significance of the Microscopic Examination in the Diagnosis of Mammary and Abdominal Neoplasias in Cats

76 cats were clinical examined for mammary and abdominal neoplasias. In 41 cats were performed microscopic examination. Regarding the location of the primary tumors 70 cats had mammary tumors. Isolated, six cases of primary non-mammary tumors were diagnosed following necropsy and histopathology. Following cytopathological and histopathological examinations, 14 tumor types were identified, of which 3 benign and 11 malignant. Benign tumoral types consisted of lipoma, vesical leiomyoma and mammary adenoma. Diagnosed malignant cases consisted of simple mammary adenocarcinoma, solid adenocarcinoma, compact adenocarcinoma, hepatic cholangiocarcinoma, compact carcinoma, mixed pulmonar bronchioloalveolar carcinoma, hemangiosarcoma, mammary comedocarcinoma, solid carcinoma and mixed adenocarcinoma

Yersiniosis outbreak in rainbow trout (Oncorhynchus mykis) at a fish farm from Northern Romania

Yersiniosis (Enteric diseases – red mouth) is a septicemic infectocontagious disease of salmonides, produced by Yersinia ruckeri, young rainbow trout being the most susceptible to infection. The disease appears as an exogenous or endogenous infection, influenced by favouring factors. The infection sources are represented by sick and asymptomatic carrier fishes that eliminate Yersinia through faeces, contaminating water and fodder. At the beginning of the disease outbreak, which is the subject of the present scientific paper, sudden water warming (15-17ºC) in the spring of 2008 was incriminated. The bacteriological examination carried out on the anterior kidney and heart blood from trout suspected of yersiniosis had as result the isolation of some Yersinia ruckeri bacteriological strains, confirming the suspected diagnosis, based on lesions (high degree anaemia of oral mucosa and branchia, haemorrhagia on tongue mucosa, exophthalmia and ocular haemorrhagia). The identification of the causative agent was based on morphological aspects (gramnegative, motile and rod-shaped) and distinctive metabolic characters, tested by using API galleries. Antibiogramas pointed out the Y. ruckeri strain susceptibility to Oxytetracicline, Flumequine, Trimethoprim and Ceftiofur and a medium susceptibility to Amoxicillin and Enrofloxacin

Effect of the over-ageing treatment on the mechanical properties of AA2024 aluminum alloy.

The evolution of the hardness of the over-ageing AA2024 alloy scale was followed by measurements of Vickers hardness. The nanoindentation is adapted to the determination of elastoplastic properties (hardness and Young’s modulus) of the matrix and also of coarse intermetallic precipitates. Influence of the artificial over-ageing time to hardness and to mechanical properties as the local scale was investigated

Estimation of laparotomic incision lengh in corelation with uterine size

The objective of this article is to find a way to estimate the lengh of the laparotomic incision after the size of the organ that needs to be removed was measured using an ultrasound machine. Incision size is a very important aspect in post-surgery recovery. A small incision leads to a faster recovery, reduces the risc of post-surgery infections, it leads to less pain for the animal and a lesser inflamatory response. An incision made at first too small needs to be lengthened until it gets to the proppers size and that means extending the time of surgery, producing unnecesary trauma by makeing multiple cuts and increasing the risk of error. We used a total of 25 queens and 18 bitches for this study. We performed an ultrasound exam on each animal and determened the size of the uterine horns and ovaries. Than we used the area of the largest section to estimate the lengh of the incision

Short-term heart rate variability in healthy dogs and dogs in various stages of degenerative mitral valve disease evaluated before pharmacotherapy

Mitral valve disease (MVD) progression is associated with autonomic nervous system (ANS) imbalance. This study hypothesized that sympathetic and parasympathetic tones would be altered with MVD progression. ANS activity was assessed among different MVD classes in untreated dogs. This cross-sectional retrospective study included 29 healthy control dogs and 71 dogs with MVD divided according to American College of Internal Medicine (ACVIM) guidelines. Heart rate variability (HRV) analyses utilised time and frequency domains and were derived from 5 min, six-lead electrocardiogram recordings of sinus rhythm or respiratory sinus arrhythmia. While all time domain-related HRV parameters decreased with disease severity, only dogs in stage C exhibited significantly lower values (P < 0.05). High frequency (HF) band values decreased more than low frequency (LF) band values as disease severity increased (P < 0.05). The LF/HF ratio also progressively increased with MVD severity. A negative correlation was observed between HRV parameters and La/Ao ratio when the entire MVD case population was pooled (P < 0.05). Both sympathetic and parasympathetic tones were altered in dogs with MVD before clinical signs were observed and prior to the development of cardiomegaly. This is the first HRV study in untreated dogs with MVD. Investigating ANS imbalances preceding subclinical left-sided cardiomegaly in dogs with MVD should be considered in future age-matched, longitudinal studies to determine the potential benefits of early vagal tone augmentation in high-risk canine patients

Cardiac biomarkers in clinical practice of dog and cat - a review

A biomarker is an indicator of a normal or pathologic process, or a pharmacologic response to a therapeutic intervention. Nowadays, in veteriary cardiology, the most used biomarkers for assessing the pathological status of the cardio-vascular system, are B-type natriuretic peptide and cardiac troponins. These biomarkers have been very well studied in cardiac pathology in order to assess their diagnostic potential. The aim of the present paper was to discuss the structure, metabolism, function, applicability, reference values and variations in different diseases and to review some practical aspects of the two cardiac biomarkers, used nowadays in small animal cardiology
