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
â 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 (15-17ÂșC) 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 Youngâs 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
