Definitive Role

Acetaminophen, commonly known as paracetamol, is a non-steroidal anti-inflammatory drug commonly used in human medicine for its antipyretic and analgesic action. As paracetamol became readily available in many over-the-counter and no-prescription products, reports of paracetamol poisoning in dogs and cats became more common. The toxicity of paracetamol is more pronounced in cats when compared to dogs. Clinical signs of paracetamol toxicity include depression, weakness, tachypnea, dyspnea, vomiting, hypothermia, facial or paw edema, hepatic necrosis, and death. The characteristics of severe paracetamol poisoning are methemoglobinemia, cyanosis, anemia, and jaundice. Although there are no specific antidotes, acetylcysteine is the drug of choice for paracetamol poisoning treatment. Symptomatic and supportive therapies play a more definitive role in the management of paracetamol poisoning. This paper aims to briefly review the clinical symptoms, diagnosis, and treatment of paracetamol poisoning in dogs and cats.

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.

The susceptibility of laboratory rats (Rattus norvegicus) to experimental inoculation with tachyzoites of Neospora caninum was examined. Groups of female rats were intramuscularly injected with 0, 2, or 4 mg of methylprednisolone acetate (MPA) 7 days prior to, and on the day of, subcutaneous inoculation with 0 or 1.5 × 105 tachyzoites. Clinical signs of disease or deaths did not occur in rats given nothing or only N. caninum tachyzoites. Rats given only 4 mg MPA failed to grow as well as rats given nothing or only N. caninum tachyzoites but were otherwise healthy. All of 20 rats given 4 mg MPA and tachyzoites died of hepatitis and pneumonia within 12 days postinoculation. Hepatic necrosis was the most striking lesion seen in these rats, and other milder lesions consisted of pneumonia, encephalitis, and myositis. The response of rats given 2 mg MPA and tachyzoites was less severe. Three of 20 rats died with encephalitis, myositis, hepatitis, and pancreatitis. Mild lesions, but no N. caninum tachyzoites, were seen in 3 of 14 rats inoculated only with tachyzoites. Rats given the 4 mg MPA treatment and inoculated with N. caninum tachyzoites appear to be suitable subjects for examining acute neosporosis and could be used in studies designed to examine treatment of acute disease.

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.

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.

This study aimed to evaluate the efficacy and toxicity of tenofovir (TDF) and TDF combined with emtricitabine (TDF/FTC) in patients with mild to moderate COVID-19 infections. We conducted a randomized, double-blind, placebo-controlled clinical trial in patients with clinical suspicion of mild to moderate respiratory infection caused by SARS-CoV-2 who were treated at an outpatient clinic. Patients were randomly recruited to take 10 days of TDF (300 mg/day), TDF (300 mg/day) combined with FTC (200 mg/day) or placebo Vitamin C (500 mg/day). The primary parameter was the score of symptoms and predictive signs of COVID-19, assessed on the seventh day of patient follow-up. From a total of 309 patients with clinical suspicion of SARS-CoV-2, 227 met the inclusion criteria and were randomly distributed into the following groups: (a) 75 (one did not initiate treatment) in the TDF group; (b) 74 in the TDF combined with FTC group; and (c) 77 in the Vitamin C group (placebo). Of the 226 patients, 139 (62%) were positive for SARS-CoV-2. Fever (37.8oC), ageusia or dysgeusia, anosmia or dysosmia, and two or more clinical symptoms or signs were significantly associated with SARS-CoV-2 infection. There was no significant change in clinical score based on clinical symptoms and signs between treatment groups. Patients with mild to moderate infection by SARS-CoV-2 had higher concentrations of G-CSF, IL-1β, IL-6 and TNF-α compared to patients without infection. Patients with mild to moderate respiratory infection, with fever (37.8oC), loss of smell, loss of taste and two or more symptoms, have a better prediction for the diagnosis of COVID-19. Patients with SARS-CoV-2 showed higher and more persistent proinflammatory cytokines profile compared to patients not infected with SARS-CoV-2. Pharmacological intervention with TDF or TDF combined with FTC did not change the clinical signs and symptoms score in mild to moderate respiratory infection in patients with SARS-CoV-2 compared to the Vitamin C group (placebo).

Annotation. Respiratory diseases are relevant in pediatric practice, which is associated with its widespread and frequent complications, especially in young children. The aim of the study was to assess the diagnostic value of clinical symptoms, laboratory and ultra-sonographic parameters in pneumonia in children of the first 3 years of life. A retrospective study of medical records of 218 children who were hospitalized in the department for young children diagnosed with pneumonia for the period from 2016 to 2018. The average age of children was 11.67±9.97 months and it was within the range from 1 month to 3 years. The ration of boys and girls was practically identical (51.8% and 48.2% accordingly). The first group included children aged under one year (the average age is 4.57±0.84 months; n=88). The second group included children aged from 1 to 3 years (the average age is 18.2±4.25 months; n=130). To characterize the information content of clinical and laboratory symptoms the study has used objective parameters defined as the operational characteristics of tests. The most important operational characteristics of diagnostic methods included: sensitivity (Se, sensitivity) and specificity (Sp, specificity). To check the statistical hypothesis on differences of absolute and relative frequencies, fractions, and ratios in two independent samples, the criteria of хі-square (χ2) was used. While detailing an anamnesis, the disease was more often related to untimely treatment and outpatient care. Various data were obtained on the absolute and relative risk, as well as the sensitivity and specificity of the localization of pneumonia depending on age. Therefore, the incidence of bilateral pneumonia was considered an indicator of risk. On admission to hospital, the body temperature of patients was 38.2±0.66°С. Most of the complaints were on the unproductive or productive cough. Besides, in some cases, shortness of breath and runny nose were mentioned. Thus, in young children with pneumonia, a diagnostically significant clinical symptom is a bilateral lung impression (82.6%), compared with right-handed (15.1%) and left-handed (2.3%), which is significantly more common in children under 1-th year of life compared with patients 1–3 years; laboratory features are probably higher levels of liver-specific enzymes – ALT and AST in children under 1 year; ultrasonographic indicators associated with the presence of pneumonia in young children include increased liver size, gallbladder deformity, the presence of sediment in the gallbladder, dyskinesia of the biliary tract, thickening of the gallbladder wall; children under 1 year of age have a risk of liver enlargement and biliary dyskinesia.

The aim of the study was to estimate the frequency and timing of hypocalcemia after surgical treatment for primary, secondary and tertiary hyperparathyroidism. Materials and methods. 21 patients were operated for hyperparathyroidism, 15 - for primary (group 1), 6 - for secondary and tertiary (group 2). In I group the median baseline level of total serum calcium was 3.06 mmol/l, phosphorus0.9 mmol/l, and parathyroid hormone360 pmol/l. In II group all patients were on program dialysis for end-stage chronic kidney failure for at least five years. The median baseline serum total calcium level was 2.29 mmol/l, phosphorus2.64 mmol/l, and parathyroid hormone-1822 pmol/l. Results. A day after removal of the parathyroid adenoma (1 group) the level of calcium and phosphorus was normalized, the content of parathyroid hormone (median 21.4 pmol/l) significantly decreased. In one case (6.7%) on the fifth day there were clinical signs of hypocalcemia and the level of calcium decreased to 1.86 mmol/l. All patients of the second group underwent subtotal parathyroidectomy. After a day the level of parathyroid hormone significantly decreased (median227 pmol/l). The phosphorus content has returned to normal. The calcium level in all cases exceeded 2 mmol/l. On day 4-5 the total calcium content decreased and ranged from 1.14 mmol/l to 2.04 mmol/l. Four patients (66,7%) showed clinical signs of hypocalcemia. It was found that the development of hypocalcemia has a positive correlation of average value with the level of parathyroid hormone, phosphorus and negative with the content of calcium before surgery. Conclusion. The decrease in the level of total calcium with the development of clinical symptoms occurs on 4-5 days after surgery for primary hyperparathyroidism in 6.7% and for secondary or tertiary - in 66.7%. Risk factors for hypocalcemia are the baseline low level of calcium and high of parathyroid hormone, phosphorus.

BackgroundMelissococcus plutoniusis an entomopathogenic bacterium that causes European foulbrood (EFB), a honeybee (Apis melliferaL.) disease that necessitates quarantine in some countries. In Czechia, positive evidence of EFB was absent for almost 40 years, until an outbreak in the Krkonose Mountains National Park in 2015. This occurrence of EFB gave us the opportunity to study the epizootiology of EFB by focusing on the microbiome of honeybee workers, which act as vectors of honeybee diseases within and between colonies.MethodsThe study included worker bees collected from brood combs of colonies (i) with no signs of EFB (EFB0), (ii) without clinical symptoms but located at an apiary showing clinical signs of EFB (EFB1), and (iii) with clinical symptoms of EFB (EFB2). In total, 49 samples from 27 honeybee colonies were included in the dataset evaluated in this study. Each biological sample consisted of 10 surface-sterilized worker bees processed for DNA extraction. All subjects were analyzed using conventional PCR and by metabarcoding analysis based on the 16S rRNA gene V1–V3 region, as performed through Illumina MiSeq amplicon sequencing.ResultsThe bees from EFB2 colonies with clinical symptoms exhibited a 75-fold-higher incidence ofM. plutoniusthan those from EFB1 asymptomatic colonies.Melissococcus plutoniuswas identified in all EFB1 colonies as well as in some of the control colonies. The proportions ofFructobacillus fructosus,Lactobacillus kunkeei,Gilliamella apicola,Frischella perrara, andBifidobacterium coryneformewere higher in EFB2 than in EFB1, whereasLactobacillus melliswas significantly higher in EFB2 than in EFB0.Snodgrassella alviandL. melliventris,L. helsingborgensisand,L. kullabergensisexhibited higher proportion in EFB1 than in EFB2 and EFB0. The occurrence ofBartonella apisandCommensalibacter intestiniwere higher in EFB0 than in EFB2 and EFB1.Enterococcus faecalisincidence was highest in EFB2.ConclusionsHigh-throughput Illumina sequencing permitted a semi-quantitative analysis of the presence ofM. plutoniuswithin the honeybee worker microbiome. The results of this study indicate that worker bees from EFB-diseased colonies are capable of transmittingM. plutoniusdue to the greatly increased incidence of the pathogen. The presence ofM. plutoniussequences in control colonies supports the hypothesis that this pathogen exists in an enzootic state. The bacterial groups synergic to both the colonies with clinical signs of EFB and the EFB-asymptomatic colonies could be candidates for probiotics. This study confirms thatE. faecalisis a secondary invader toM. plutonius; however, other putative secondary invaders were not identified in this study.
