Streptococcus dysgalactiae Septic Arthritis of a Pre-Weaned Holstein Bull Calf - a Case Report

Septic arthritis is a joint inflammation caused by an infectious agent. Septic arthritis takes a long time to heal, and as such it may have a significant economic impact. A one-month-old Friesian Holstein calf was lame and had swelling in the left carpal joint. Synovial fluid samples from the left carpal joint were used for bacterial identification, which use API Strept 20 (bioMérieux, Inc – USA). The identification results showed that septic arthritis was caused by Streptococcus dysgalactiae subspecies dysgalactiae,. Streptococcus dysgalactiae subspecies dysgalactiae play a significant role even though it plays a major role in mastitis in dairy cows.

ANALYSIS OF THE SPATIO-TEMPORAL CHARACTERISTICS OF THE TECHNIQUE OF KICKING WITH THE LEFT FOOT TO THE SIDE FROM THE LEFT-HANDED STANCE OF HIGHLY SKILLED ATHLETES SPECIALISING IN HAND-TO-HAND COMBAT

The relevance of the research topic. A wide arsenal of technical actions and a wide range of potential conflict situations that regularly occur in the course of martial arts determine the peculiarities of operations, actions and mechanisms for their improvement. The aim of the research was to analyse the indicators of the spatial-temporal structure of the technique of a kick with the left foot to the side from the left- handed stand performed by highly skilled sportsmen. Research methods: analysis of literature sources, video recording and biomechanical video computer analysis using the optoelectronic system "Qualisys", methods of mathematical statistics. Results. The movement of the biolinks of the athletes' body during the phase of preparing for the impact is from 0.03 m to 0.25 m. During the kicking phase, the values of the average velocities of the right ankle and right knee joints are 4.23 m·s-1 and 2.26 m·s -1 respectively. Conclusions. The execution of a blow is effective from the point of view of biomechanical analysis, and the indicators of the kinematic structure of movements during the execution of this blow can be used both as a reference sample of sports technique and for the development of model characteristics of movements based on them. The values of the average velocities of the shoulder, elbow, and carpal joints of the right hand during the walking phase are 0.50 m·s-1, 1.10 m·s-1, and 0.95 m·s-1, respectively. The average speed of the shoulder joint of the left hand is 0.69 m·s-1, the left elbow joint - 0.97 m·s-1, and the left carpal joint - 2.03 m·s-1. Such high indicators of the average speeds of the hand joints during the walking phase indicate swinging movements to increase the force of the impact due to the use of inertial forces. The movement of the biolinks of the athletes' body during the walking phase ranges from 0.08 m to 0.63 m. The values of the indicators of the joints of the upper limbs during the two support phases when performing a left leg kick to the side from the left stance are: right shoulder joint - 0.65 m·s-1, left shoulder joint -0.52 m·s-1, right elbow joint – 2.73 m·s-1, left elbow joint – 1.71 m·s-1, right and left carpal joints – 1.84 m·s-1. In the two-support phase, the movement of the studied body points of the athletes is in the range from 0.08 m to 0.56 m. The values of the average velocities of the studied body points of the athletes during the contact phase when performing a left leg kick to the side from the left stance range from 0.23 m s- 1 to 2.53 m·s-1, and the displacement of the same points during this phase is from 0.02 m to 0.20 m

Topicality. Taking into account the physical conditions for the implementation of the necessary motor task, which directly affect and impose requirements on the level of technical, physical, and theoretical preparation of the performer, in order to achieve the desired final result of the athlete’s mechanical actions, a deep understanding of the importance of the relationship between the chosen technical method of performing a sports exercise and the biomechanical parameters of the performer’s movement is required as factors of the effectiveness of the implementation of this method of action. Objective of the Study is analysis of the speed characteristics of a blow from below to the head with the right hand from the front stance in highly qualified athletes who specialize in hand-to-hand combat. 12 highly qualified athletes took part in the research. Among them were 7 masters of sports of Ukraine and 5 masters of sports of international class. The following Research Methods were used in the study: theoretical, pedagogical, mathematical. Results of the Research. We analyzed the average speed indicators in different phases of a blow from below to the head with the right hand from the frontal stance in highly qualified athletes. Indicators of average velocities of various points of the body in the phase of preparation for impact, the highest velocities are the left carpal joint 0,93 m•s-1, the left elbow 0,69 m•s-1 and the left shoulder joints 0,65 m•s-1 respectively. The average velocities of the points of the right leg: ankle, knee and hip joints are 0,6 m•s-1, 0,96 m•s-1 and 1,12 m•s-1, respectively. Analogous indicators of the average velocities of the points of the left leg are 0,06 m•s-1, 0,55 m•s-1 and 0,64 m•s-1, respectively. Conclusions. The outlined problem for a wide range of scientific knowledge on sports training is not new, however, it is especially relevant for hand-to-hand combat due to the specifics of the implementation of motor actions.

Mycoplasma bovis arthritis and pneumonia in calves in Jordan: An emerging disease.

Aim:Clinical, microbiological, molecular, and pathological assays were undertaken to characterize an outbreak of increasingly reported signs of unresponsive arthritis and pneumonia of Mycoplasma bovis infection in young calves in Jordan.Materials and Methods:Clinical history of the affected bovine herd was investigated for the presence of respiratory and/or joint problems. Two calves with such history were clinically examined and necropsied. Representative tissues were sent for microbiological, molecular, and pathological examinations for M. bovis infection.Results:The outbreak started in a herd of 220 nursing calves, 2 months before the receiving of two calves for postmortem examination. Clinically, respiratory signs and infection of one or more joints dominated in the affected calves. The morbidity and case fatality rates were 27.27% and 61.7%, respectively. The left carpal joint was markedly swollen in both calves and exhibited necrofibrinous to granulomatous arthritis in varying degrees of severity. The anteroventral lung lobes in both calves were consistently affected and revealed multifocal to coalescing severe necrogranulomatous and fibrinopurulent bronchopneumonia. Microbiological and molecular findings confirmed the pathological examination. Furthermore, bovine viral diarrhea (BVD) was diagnosed in one calf by histopathology and polymerase chain reaction.Conclusion:This investigation reports the first outbreak of M. bovis infection in calves located in Jordan that could occur concurrently with BVD.

Changes in Synovial Fluid Biomarkers after Experimental Equine Osteoarthritis.

IntroductionThe study aimed to clarify the changes in the concentration of inflammatory mediators, proteases, and cartilage degradation biomarkers in the synovial fluid of joints in an equine osteoarthritis model.Material and MethodsOsteoarthritis was induced in eight Mongolian horses by a sterile intra-articular injection of amphotericin B, which was injected into the left carpal joint in a dose of 2 mL (25 mg/mL). The control group comprised five horses which were injected with an equal dose of sterile physiological saline into the left carpal joint. Synovial fluid was obtained at baseline and every week after injection. Test methods were based on ELISA.ResultsIn the course of the osteoarthritis, the concentration of biomarkers in joint synovial fluid showed an increasing trend. IL-1, IL-6, MMP-9, MMP-13, ADAMTS-5, CS846, GAG, HA, CTX-II, and COMP concentrations sharply increased before the onset of significant symptoms of lameness, whereas TNF-α, MMP-2, and MMP-3 concentrations rose sharply after the occurrence of such symptoms.ConclusionThe results obtained confirm that the concentrations of IL-1, IL-6, MMP-9, MMP-13, ADAMTS-5, CS846, GAG, HA, CTX-II and COMP increase substantially in equine osteoarthritis, which provides a theoretical basis for the rapid diagnosis of the disease.

Experimental study on blood gases and acid-base parameter changes following oral administration of injectable enrofloxacin 5 % to the horses

The objective of this investigation was to evaluate the effects of oral administration of bovine injectable enrofloxacin 5 % on blood gases, acid–base parameters, risk of gastrointestinal ulcers, bleeding, diarrhea, abdominal pain, and clinical joint disturbances in horses. For this purpose, there were nine selected mixed breed horses with ages between 11 month and 15 years old. These horses were divided into three groups of three animals. Bovine injectable enrofloxacin 5 % was administered orally, 5 mg/kg to the first group and 15 mg/kg to the second group, every 12 h, for 21 days. The third or control group did not receive drug but saline in the same way. Heparinized blood samples were collected for evaluation of blood electrolytes and blood gas parameters as well as recording the clinical findings in animals. Occult blood test was performed in all horse stool samples, in five times, before and after the administration of the drug. As a result, the analyzed data did not show significant changes in blood gases and electrolyte parameters, between drug-administered and control groups. There were no observed mucosal ulcer, injury or symptoms of diarrhea, abdominal pain, and gastrointestinal bleeding in the horses. One of the horses showed swollen in the left carpal joint with a dose of 5 mg/kg of drug, at day 12, which improved with suitable treatment until day 20. This study showed that 3 weeks of oral administration of enrofloxacin 5 % had no significant effect on blood gases and electrolyte parameters even at high doses (15 mg/kg). This study showed the lack of drug effect on producing gastrointestinal mucosal ulcers and colic pain in the drug-treated horses. It was recommended that the drug enrofloxacin should not preferably be used in foals and also in mature horses for long duration, because of the possible joint disorder, and its usage should be with caution.

Peri‐articular Histiocytic Sarcoma and Previous Joint Disease in Bernese Mountain Dogs

Peri-articular histiocytic sarcoma (PAHS) occurs in dogs, including Bernese Mountain Dogs (BMD). An etiologic relationship with previous joint disease has not been documented. Peri-articular histiocytic sarcoma in BMD will be more frequently encountered around previously diseased joints compared with normal joints. 920 European BMD. A retrospective study, in which data were obtained through an Internet questionnaire and from 2 veterinary pathology laboratories. Archived samples of hematoxylin-eosin (H&E) staining diagnosed PAHS and synovial cell sarcoma (SCS) were immunolabeled with CD18 and pancytokeratin. Descriptive, comparative, and actuarial statistics comprise the data analysis. All primary synovial tumors were identified as PAHS based on their morphology, positive CD18, and negative pancytokeratin labeling. Joint disease was diagnosed in 226 BMD, of which 15 developed PAHS in a previously diseased joint and 3 in a nondiseased joint. Of the remaining 694 BMD without joint disease, 9 developed PAHS. The odds ratio for a dog with previous joint disease developing PAHS is calculated as 5.4 (95% CI: 2.3-12.5; P<.0001) compared with no previous joint problem. A significant association between previous joint disease and PAHS in the same joint was demonstrated for the left elbow (P=.016), right elbow (P=.006), right shoulder (P=.047), left and right stifle (P<.001), and left carpal joint (P=.010). The results of this study suggest a relation between previous joint disease and the development of PAHS in the same joint of European BMD. Owners of BMD should monitor dogs for peri-articular swellings, particularly around previously diseased joints.

A Case of Traumatic Myiasis in a Domestic Rabbit (Oryctolagus cuniculus) Caused By Lucilia sericata

Lucilia sericata is one of the factors resulting in facultative traumatic myiasis in animals and humans. L. sericata threatens human health and leads to significant economic losses in animal industry by leading to serious parasitic infestations. A three month old female rabbit was presented to the clinics of the Veterinary Faculty of Dicle University for the treatment of the wound located on the left carpal joint. The examination revealed that the wound was infested with larvae. The microscopic inspection of the larvae collected from the rabbit showed that they were the third instar larvae of L. sericata.

Chondrosarcoma in a dromedary camel (Camelus dromedarius)

A 4-year 10-month-old, intact female dromedary camel had progressive left carpal joint swelling and lameness for 7 months. Radiographs showed multifocal lytic lesions in the carpal and proximal metacarpal bones. Surgical biopsy of the synovial capsule and carpal bones suggested neoplasia, and the camel was subsequently euthanized. At necropsy, a white to pale pink, firm, multilobulated, soft tissue mass was located on the palmar aspect of the left carpal joint. Two smaller masses were present on the dorsal aspect of the carpal joint. The masses infiltrated all the carpal bones and the proximal region of the metacarpal bone. The joint capsule was diffusely thickened. The articular surfaces of the carpal bones and the metacarpal bone were multifocally eroded. The lungs contained multiple, firm, raised, gray, randomly distributed nodules. The neoplastic cells stained positive for vimentin and S-100. Chondrosarcoma arising from around the carpal joint with infiltration of carpal and metacarpal bones, and pulmonary metastasis, was diagnosed based on the histopathological and immunohistochemical evaluation.

Hypertrophic Osteopathy Associated with Disseminated Metastases of Renal Cell Carcinoma in the Dog: A Case Report

A 6-year-old, mixed breed, intact male dog showed signs of left carpal joint swelling and weakness of the forelimbs one month before presentation. The symptoms gradually progressed to bilateral carpal and tarsal joint swelling and tetraparalysis. There were a number of radiographically identified lytic-proliferative bone lesions noted on the axial skeleton. Hypertrophic osteopathy of the metacarpi and all distal long bones was also evident. Because of the deteriorating quality of life and guarded prognosis, the patient was euthanized and a complete necropsy was performed. Renal cell carcinoma, with metastasis to the lung, thoracic vertebrae, ribs, and the right adrenal gland, was diagnosed. To our knowledge, renal cell carcinoma with bone metastases and hypertrophic osteopathy has not been reported in dogs.

A case of multiple abscesses in a baby elephant

A captive-born three month-old baby elephant weighing about 100kg at Jenabil Elephant Camp developed multiple wounds at its navel region, left knee joint, area below left ear and sternal region. It was treated with povidone-iodine (Betadine) lotion and a course of parenteral strepto-penicillin (Bistrapen). The wounds healed in a month, with development of two fluctuating swellings one at right stifle joint and other at left carpal joint. The elephant calf was limping in the affected limbs. It was decided to explore the swellings surgically to drain the contents under sedation.

Increase in substance P and CGRP, but not somatostatin content of innervating dorsal root ganglia in adjuvant monoarthritis in the rat

Neuropeptides, synthesized in dorsal root ganglia (DRG), are implicated in nocioception and neurogenic inflammation. Alterations in DRG neuropeptide levels have been described in polyarthritic rats, but these models are associated with widespread systemic disease. Using mild adjuvant-mediated monoarthritis of the left carpal joint we found significant increases in substance P (+69%) and calcitonin gene-related peptide (CGRP; +204%), but not somatostatin in ipsilateral C6/7 DRG. Peptide levels in contralateral DRG and other ipsilateral DRG were unaltered. Substance P and CGRP in DRG may be of importance in the pathogenesis and maintenance of adjuvant arthritis.

Metastasising canine fibrosarcoma originally diagnosed as haemangiopericytoma.

ABSTRACTHaemangiopericytoma of the left carpal joint region was diagnosed in a biopsy from a 13‐year‐old Cocker Spaniel. Six months later, there was recurrence at the original site with pulmonary metastases. Ultrastructural examination revealed that the neoplastic cells did not have an enveloping membrane. Since the finding of such membranes is characteristic of human pericyte tumours, the canine growth was classified as a fibrosarcoma. It is suggested to re‐evaluate the use of the term haemangiopericytoma in veterinary medicine.
