Background. Canine babesiosis is a clinically important hemoprotozoan parasite affecting dogs. The goal of this present study was to determine the clinical symptoms and to establish its hematological and microscopic detection and compare it with the PCR findings attained from dogs infected withBabesia canis vogeli.Methodology/Principal Findings. 13-PCR confirmed Babesia-infected dogs were examined; seminested PCR was used to discover the precise type ofBabesiaandBabesia canis vogeliwas the only subspecies detected. The most consistent clinical signs were elevated rectal temperature and a pale mucous membrane. Thrombocytopenia, monocytosis, and lymphocytosis, along with a significant reduction in red cell parameters, were the most commonly recorded hematologic alterations. Microscopic examination revealed the presence of typical large merozoites and trophozoites ofB. canisin the ratio 76.92%.Conclusions/Significance. The presumptive diagnosis of canine babesiosis should be based on a fever and anemia, while thrombocytopenia is considered the hallmark of the disease; microscopic examination may not be very revealing in the detection at low parasitemia, but it remains the most rapid confirmatory method. Seminested PCR turned out to be a sensitive and accurate method for diagnosis; during the process of differentiation betweenBabesiasubspecies, onlyB. canis subsp. vogeliwas detected.

Abstract This epizootiological study was carried out to investigate the occurrence of canine babesiosis in southwestern Slovakia. The study focused on the proportion of the species of ticks serving as babesia vectors of babesiosis in the ticks collected from selected locations close to Komárno, in southwestern Slovakia. Additionally, observations were made on the health and overall clinical signs in dogs suspected of having babesiosis. In 2014 we collected ticks from vegetation by the drag cloth (flagging) method and also directly from dogs. A totally of 622 ticks were collected: 491 Dermacentor reticulatus and 131 Ix-odes ricinus. Representative samples of ticks (n = 103) were examined by the molecular method and the presence of Babesia spp. DNA was identified in 12.5 % of the Ixodes ricinus ticks collected by flagging and in 9.5 % of the Ixodes ricinus ticks collected from the dogs. Babesia canis (KU681325) with 90 bp sequence, 100 % identical with Babesia canis isolates from dogs for example from: Turkey (KF499115), Rumania (HQ662634), Croatia (FJ209025), Poland (EU622792) and Russia (AY962186), was confirmed after sequencing in one Ixodes ricinus female obtained from a dog. This was the first confirmation of the occurrence of B. canis in Ixodes ricinus ticks in Slovakia. In 2.2 % of the Dermacentor reticulatus ticks obtained from vegetation by flagging, we were able to diagnose the DNA of Babesia canis. In 4.8 % of the Dermacentor reticulatus ticks collected from dogs, the presence of Babesia spp. was confirmed. Thirty three dogs with suspicion of babesiosis were observed in an ambulance by their health and clinical signs. The loss of appetite was observed in 22 patients (66.7 %), apathy in 19 cases (57.6 %), and fever in 19 cases. Closer specification indicating babesiosis was finding engorged ticks on the dog bodies which occurred in 21 cases (63.6 %), haematuria in 8 cases (24.2 %), anaemia in 4 cases (12.1 %), and tremor in 6 cases (18.2 %). Other non-specific signs, such as diarrhoea, vomitus, slowed-down movement, ataxia and lacrimation were also observed in less than 18 % of the examined dogs. On the basis of the specific clinical signs, blood was withdrawn from 33 dogs for preparation of blood smears and in 19 of them (57.6 %) babesia in erythrocytes were confirmed microscopically.

Metaldehyde is an active substance used for extermination of slugs and snail population. This paper presents the very first case of metaldehyde intentional poisoning of dogs in Serbia. Three-year-old and a six-year-old Swiss white shepard dogs were poisoned. The owner noticed frequent defecation, skeletal muscles spasms and impossibility to put any weight on their back extremities. The vomit of the younger dog was made of green-turquoise colored gut content. Twenty minutes after the onset of the first clinical symptoms dogs died. Macroscopic examination showed congestion of lungs, in the liver and intestines, as well as chemorage in the pancreas, bladder and intestines. Nonspecific pathological lesions were present in the lungs, heart, kidneys, liver, gut, intestines and brain. Pathohistological examination showed dystrophic changes and necrosis in kidneys, brain and intestines. According to anamnestic data, clinical signs, macroscopic and microscopic examination as well as characteristic smell of gut content, one could say that metaldehyde poisoning is the case. Toxicological analysis of gut content samples was performed by using gas chromatography with mass spectrophotometry (GC-MS). Used diagnostic methodology and gut content toxicology results obtained was the base for crime case according to article 269. Republic of Serbia Crime law.

Gonococcal Urethritis

The primary pathogens found in men with urethritis are Chlamydia trachomatis and Neisseria gonorrhoeae. Rapid diagnosis of N. gonorrhoeae infection can be made based on a Gram- or methylene blue-stained urethral smear. We describe a case of a man with purulent penile discharge, in which microscopic examination led to the presumptive diagnosis of gonorrhoea. A nucleic acid amplification test was negative for N. gonorrhoeae but positive for C. trachomatis. Culture showed Gram-negative diplococci which were identified as Neisseria meningitidis. N. meningitidis can be sporadically pathogenic in the genito-urinary tract and mimicks gonococcal urethritis, and appears identical by microscopy. When a gonococcal urethritis is suspected based on clinical signs and microscopic examination, but investigatory tests cannot confirm the diagnosis, a N. meningitidis infection should be considered.

Abstract Background Enlargement of the prostate is associated with prostatic diseases in dogs, and an estimation of prostatic size is a central part in the diagnostic workup. Ultrasonography is often the method of choice, but biomarkers constitute an alternative. Canine prostate specific esterase (CPSE) shares many characteristics with human prostate specific antigen (PSA) and is related to prostate size. In men with clinical symptoms of prostatic disease, PSA concentrations are related to prostate growth. The aims of the present follow-up study were to evaluate if the concentration of CPSE is associated with future growth of the prostate, and if analysis of a panel of 16 steroids gives further information on prostatic growth. Owners of dogs included in a previous study were 3 years later contacted for a follow-up study that included an interview and a clinical examination. The prostate was examined by ultrasonography. Serum concentrations of CPSE were measured, as was a panel of steroids. Results Of the 79 dogs included at baseline, owners of 77 dogs (97%) were reached for an interview, and 22 were available for a follow-up examination. Six of the 79 dogs had clinical signs of prostatic disease at baseline, and eight of the remaining 73 dogs (11%) developed clinical signs between baseline and follow-up, information was lacking for two dogs. Development of clinical signs was significantly more common in dogs with a relative prostate size of ≥2.5 at baseline (n = 20) than in dogs with smaller prostates (n = 51). Serum concentrations of CPSE at baseline were not associated with the change in prostatic size between baseline and follow-up. Serum concentrations of CPSE at baseline and at follow-up were positively associated with the relative prostatic size (Srel) at follow-up. Concentrations of corticosterone (P = 0.024), and the class corticosteroids (P = 0.0035) were positively associated with the difference in Srel between baseline and follow-up. Conclusions The results support the use of CPSE for estimating present and future prostatic size in dogs ≥4 years, and the clinical usefulness of prostatic size for predicting development of clinical signs of prostatic disease in the dog. The association between corticosteroids and prostate growth warrants further investigation.

Abstract:Experimental allergic neuritis (EAN) in Lewis rats was treated with prednisolone given prophylactically or therapeutically. Rats treated from the time of immunization with myelin or after the establishment of clinical disease improved more rapidly than controls. Treatment at the onset of clinical signs resulted in less severe disease and more rapid recovery. Rats treated just prior to the onset of clinical signs (day 10) did not develop significant clinical disease and appeared to have less inflammation in their nerves and nerve roots on microscopic examination.

Seven patients with petit mal seizures treated with trimethadione, ethadione, or paramethadione for long periods were subjected to renal biopsy at the age of 14½ 16½ years. None of the patients had clinical signs of renal disease at the time of the biopsy, but three of them had previously shown transient hematuria or proteinuria. The renal histology was studied by conventional methods and by electron microscopy, the latter method only including the glomeruli. The changes found must with the present knowledge be regarded as physiological. A short report is given of a patient with phenylketonuria and epilepsy who developed a nephrotic syndrome during treatment with tridione. No definite pathologic renal changes were demonstrated at the when the clinical symptoms had disappeared.

Abstract Background and Aims The prevalence of central vein stenosis (CVS) in patients on hemodialysis (HD) is difficult to be assessed directly. This is mainly caused by the variety of clinical signs and the high frequency of asymptomatic CVS. Aim: to assess the frequency of occurrence of various CVS forms in HD patients. Method The retrospective observational study is based on the results of treatment of 1865 HD patients who underwent diagnostic and therapeutic procedures on vascular access in our center. In case of vascular access dysfunction, patients were examined according to a local protocol: ultrasound of the peripheral (to exclude lesion of peripheral AVF segments) and central veins (over the available length), followed with CT-angiography or percutaneous angiography, if necessary. Results AVF/AVG dysfunction was observed in 29.4% of patients (549 of 1865). 211 patients were diagnosed with CVS. The prevalence of CVS was 11.3% (211 of 1865) among all HD patients and 38.4% (211 of 549) in patients with AVF dysfunction. Among patients with CVS, 37% (78 of 211) had vein lesions without clinical symptoms or with minimal manifestations (a tendency to decrease KT/V). The prevalence of asymptomatic CVS was 4.2% (78 of 1865) in the general population of HD patients and 14.2% (78 of 549) in patients with AVF dysfunction. In case of asymptomatic CVS it was detected by an ultrasound examination during CVC implantation (N=38), during unsuccessful attempts to implant CVC (N=29), in the case of recurrent AVF thrombosis without underlying peripheral segments lesion (N=9) or during echocardiography (N=2). The prevalence of asymptomatic CVS among patients without AVF dysfunction was 5.9% (78 of 1316). True prevalence of subclinical CVS among HD patients without obvious signs of AVF dysfunction may vary widely. A total of 48.8% (103 of 211) of all CVS cases were treated. At the same time, in 10.7% (11 of 103) of cases, patients did not present symptoms of CVS, and surgery was performed due to recurrent AVF thrombosis without damage of the peripheral parts of AVF. Patients with clinically manifest CVS who received endovascular interventions had a significantly higher risk of AVF loss compared to patients with asymptomatic CVS: HR=2.566 [95% CI 1.706; 3.86], log rank p<0.0001. However, patients with an asymptomatic CVS had a higher risk of AVF function loss compared to the general HD population (HR=2,051 [95% CI 1,243; 3,384], log rank p= 0.0004) – fig. 1. The use of CVC is a known risk factor of CVS development. We analyzed the relationship of CVS risk with multiply CVC placements and catheter dwell time using the Cox proportional hazards regression model (fig. 2). In the univariate model, a greater No of CVCs as well as longer time in place increased the risk of CVS. In the multivariate model (χ2=105.516, df=2, p<0.0001), catheter dwell time was no longer associated with an increased risk of CVC, while the mean number of inserted catheters remained an important risk factor. Conclusion The prevalence of both symptomatic and asymptomatic forms of CVS in HD patients is high. Patients with vascular access dysfunction should be carefully examined to identify the asymptomatic CVS. The mean No of catheterizations is a more important risk factor of CVS than longer catheter dwell time.

Heartwater is a serious limiting factor for sheep and goat production in the major endemic area of sub-Saharan Africa and therefore most knowledge, research and control methods originate from this region. Whilst the usual or common clinical presentations can be used to make a presumptive diagnosis of heartwater with a good measure of confidence, this is not always the case, and animals suffering from heartwater may be misdiagnosed because their cases do not conform to the expected syndrome, signs and lesions. One aberrant form found occasionally in the Channel Island breeds of cattle and some goats is an afebrile heartwaterlike syndrome. The most constant and characteristic features of this heartwater-like syndrome comprise normal temperature, clinical signs associated with generalised oedema, and nervous signs, especially hypersensitivity. The presumption that the disease under investigation is the afebrile heartwater-like syndrome entails a tentative diagnosis based on history and clinical signs and the response to presumed appropriate treatment (metadiagnosis). The afebrile heartwater-like syndrome presents similarly to peracute heartwater but without the febrile reaction. Peracute cases of heartwater have a high mortality rate, enabling confirmation of the disease on post-mortem examination. Recognition of the afebrile heartwater-like syndrome is important to prevent deaths and identify the need for appropriate control measures.

ABSTRACTLaminitis in horses is often associated with endocrine disorders, especially the pituitary pars intermedia dysfunction (PPID) in older animals. Morphologic exams of the laminar tissue of the hoof were performed in two horses with suspected PPID, with no clinical signs of laminitis. Changes compatible with laminitis of endocrine origin were observed, such as rounding of the nuclei of the basal cells, thinning and stretching of the secondary epidermal laminae and tissue proliferation. PPID horses with no clinical signs of laminitis may be affected by lesions of the laminar tissue of the hoof that compromise the integrity of the dermal-epidermal junction and may develop clinical symptoms of the disease. It has been suggested that the development stage of endocrine laminitis is longer, but further studies should be conducted to confirm it.

BACKGROUND: Symptoms and clinical signs suggestive of deep vein thrombosis (DVT) are common but may have numerous possible causes. OBJECTIVES: 1) To identify the most frequent clinical symptoms and correlate them with duplex ultrasound scan (DS) findings; 2) to identify high-risk clinical conditions for DVT; and 3) to evaluate time since the onset of symptoms and DS examination. METHODS: A total of 528 patients with a clinical suspicion of DVT were evaluated by DS performed by experienced vascular ultrasonographists. RESULTS: DVT was present in 192 (36.4%) of the patients. The external iliac vein was involved in 53 patients (10.04%), the femoral veins in 110 (20.83%), the popliteal vein in 124 (23.48%), and veins below the knee were involved in 157 (29.73%) of the cases. Limb swelling was present in 359 cases (68%), and 303 (57.4%) complained of pain. Sixty nine patients received a DS due to suspected or proven pulmonary embolism (PE); 79 patients were in postoperative period. In the multivariate analysis, independent risk factors for DVT included age>65 years (OR=1.49; 95% confidence interval [95%CI] 1.01-2.18; p=0.042), edema (OR=2.83; 95%CI 1.72-4.65; p<0.001), pain (OR=1.99; 95%CI 1.3-3.05; p=0.002), cancer (OR=2.32; 95%CI 1.45-3.72; p<0.001), and PE (OR=2.62; 95%CI 1.29-5.32; p=0.008).Time since the onset of symptoms did not differ between the groups. CONCLUSIONS: In the present study, 36.4% of the patients referred to DS had DVT. Age > 65 years, presence of limb swelling, pain, cancer, and suspected or proven PE should be considered as major risk factors for DVT.
