Summary Objective: This study summarizes the clinical, serological, pathomorphological and laboratory findings in 19 sheep with spontaneous Visna in Germany. The cases occurred over a period of 13 years in 13 flocks. In all affected sheep cytologic examination of cerebrospinal fluid (CSF) was performed. In addition in six flocks from which 12 of the Visna cases came the whole flock was tested for Maedi/Visna virus (MVV) antibodies. Material and methods: The diagnosis of spontaneous Visna with typical clinical signs was proven by serological and histopathological investigations. Serological screening for MVV antibodies was performed with the agargel-immuno- precipitation-test (AGIDT). Additionally, cerebrospinal fluid (CSF) was obtained by lumbosacral puncture and examined cytologically. Results: Nine of the 19 cases were Texels and six East Frisian Milk sheep. Six out of nine Texels came from the same flock with a MVV-antibody intra-flock prevalence of 0.94. The mean age of the sheep was 3.9 ± 2.3 years (0.5–10 years). Time between onset of clinical symptoms until euthanasia due to recumbency was 35 ± 23 days (6–102 days). In most cases clinical signs started with ataxia, staggering and circling, followed by increasing paresis of the hind legs. In the late stages of the disease 14 sheep suffered from tetraparesis. Trembling of lips or eye lids, blindness and scratching were rare signs. In all cases pleocytosis (11–876 M/l, mean = 167 M/l) with mononuclear cells, predominantly macrophages, was found. This finding provides an additional diagnostic aid to support the clinical differentiation from other infectious diseases with neurological manifestation in sheep. Histopathology of the CNS revealed in most cases a severe leukoencephalitis and demyelinisation with perivascular lymphocytic infiltration. Conclusion and clinical relevance: Visna is an important differential diagnosis in CNS disorders of sheep. It also occurs in animals younger than one year. Visna occurs especially in highly infected flocks of susceptible sheep breeds. CSF cytology can help to differentiate Visna from other CNS diseases. Clinically, Visna may be an important differential diagnosis to Scrapie.

Parasites resembling Neospora caninum or Toxoplasma gondii were detected by cytologic examination of cerebrospinal fluid (CSF) from a dog with neurologic disease. The dog became severely ill and was euthanized. Canine tissue homogenates were used for direct parasite isolation in cell culture, bioassay in 2 mouse lineages, and PCR. T. gondii was isolated in monkey kidney cells, and species identity was confirmed by PCR. Inoculated parasites were highly virulent for mice, which developed clinical signs and were euthanized immediately. PCR-RFLP for T. gondii using the cultured isolate (TgDgBA22) was conducted with 12 genetic markers, and a unique recombinant strain was identified. Detection of T. gondii by CSF cytology, although described in humans, had not been reported previously in dogs, to our knowledge, and was crucial for the diagnosis of toxoplasmosis in the examined dog.

Abstract Background The ongoing COVID-19 pandemic remains a major challenge for worldwide health care systems and in particular emergency medicine. An early and safe triage in the emergency department (ED) is especially crucial for proper therapy. Clinical symptoms of COVID-19 comprise those of many common diseases; thus, differential diagnosis remains challenging. Method We performed a retrospective study of 314 ED patients presenting with conceivable COVID-19 symptoms during the first wave in Germany. All were tested for COVID-19 with SARS-Cov-2-nasopharyngeal swabs. Forty-seven patients were positive. We analyzed the 267 COVID-19 negative patients for their main diagnosis and compared COVID-19 patients with COVID-19 negative respiratory infections for differences in laboratory parameters, symptoms, and vital signs. Results Among the 267 COVID-19 negative patients, 42.7% had respiratory, 14.2% had other infectious, and 11.2% had cardiovascular diseases. Further, 9.0% and 6.7% had oncological and gastroenterological diagnoses, respectively. Compared to COVID-19 negative airway infections, COVID-19 patients showed less dyspnea (OR 0.440; p = 0.024) but more dysgeusia (OR 7.631; p = 0.005). Their hospital stay was significantly longer (9.0 vs. 5.6 days; p = 0.014), and their mortality significantly higher (OR 3.979; p = 0.014). Conclusion For many common ED diagnoses, COVID-19 should be considered a differential diagnosis. COVID-19 cannot be distinguished from COVID-19 negative respiratory infections by clinical signs, symptoms, or laboratory results. When hospitalization is necessary, the clinical course of COVID-19 airway infections seems to be more severe compared to other respiratory infections.

The prevalence and incidence of prostate cancer is gradually increasing both in our country and in countries near and far abroad. The difficulties in the differential diagnosis of prostate cancer are convincingly evidenced by the fact that the level of diagnostic errors reaches 40%. It should be noted that in assessing the differential diagnostic capabilities of the indicators of the clinical and special examination methods for patients with lower urinary tract symptoms, disagreements were found in 46–77% of the analyzed clinical signs, the changes of which mainly reflect the negative nature of the effect of tumor decay products on the patient’s body. The aim of the study was to improve the early diagnosis of prostate cancer by using the mathematical method of differential diagnosis of prostate pathology, as well as the rationale for the proposed method for early diagnosis of prostate cancer in patients with clinical symptoms. Using our proposed method for early diagnosis of prostate cancer makes the diagnosis not only reliable and accurate, but also independent of the level of qualification of the urologist and his personal experience, allows you to unify, optimize and personify the differential diagnosis of prostatic hypertrophy and prostate cancer.

Abstract Background Vitamin D3 has been identified as an immunomodulatory agent that confronts the pathogens via stimulating antimicrobial peptides (AMPs). Objective The effects of vitamin D3 on the expression of AMPs was assessed in experimental pasteurellosis in calves. Methods 10 Holstein crossbred male calves (2–4 months) were chosen and randomly divided into the two groups. Pasteurella multocida was prepared (3×109 CFU/mL) and inoculated in the trachea. Vitamin D3 was injected to the treatment group after confirming the pneumonia. Blood samples were obtained from both groups at different time intervals and the peripheral blood mononuclear cells (PBMCs) were isolated. Clinical symptoms were recorded. Broncho-alveolar lavage was performed to evaluate the lung cell content. On the other hand, 10− 6, 10− 7, and 10 − 8 molar (M) of vitamin D3, was used to evaluate the expression of CD4, BMAP34, and BNBD4 genes using PBMCs under the in vitro conditions. Results The prescription of vitamin D3 to the treatment group caused a decline in clinical signs. Following the vitamin D3 injections the treatment groups under the in vivo conditions, significant increase was observed in the expression level of Defensin (BNBD4), and CD4. Evaluation of bronchoalveolar lavage fluid (BALF) revealed that the amount of neutrophils decreased after vitamin D injection. In vitro, increased expression of Catalicidin (BMAP34), Defensin (BNBD4), and CD4 was observed at a concentration of 10− 6 M of vitamin D3. Conclusion The present study indicated that vitamin D3, exerts immunomodulatory effects on many infectious diseases via activation of VDR pathways and stimulation of AMP production.

Antibodies against myelin oligodendrocyte glycoprotein cause inflammatory lesions of central myelin – in optic nerves, of the brainstem, and spinal cord. There are characteristic changes of CNS white matter, protein-cytological association in cerebrospinal fluid, MOG IgG antibodies, a very important differential diagnosis and a relatively mild course.

Introduction: Fascioliasis is a disease of the hepatobiliary system, caused by Fasciola spp that are increasing and threating of public health in the tropic areas, including of Central coastal of Vietnam. World Health Organisation estimates that at least 2.4 million people are infected in more than 70 countries worldwide, with several million at risk, and particularly, no continent is free from fascioliasis. This study carried out to evaluate several typical clinical and paracinical aspects in the pregnant women and children groups with fascioliasis. Methods: With the descriptive cross-sectional study design, and sample size in line with hospital based data. Results: the data post-analysis showed that total of 94 pregnant women and 212 child with gigantica fascioliasis were enrolled:- In the pregnant women group: the major clinical symptoms of epigastric and Chauffard Rivet triangle pain (95.74%), subshoulder muscle pain (97.87%), gastrointestinal disturbances as abdominal pain plus constipation (14.89%), loosed stool (22.34%), nausea and/or vomit (29.78%), mild fever (68%), allergic reaction with pruritis and urticaria (64.89%), mild anemia (4.26%), rare symptoms may be hepatomegaly (6.38%), chest pain, dyspnoea (43.62%), jaundice (2.13%); Laboratory parameters were positive ELISA test with Fasciola gigantica antigen (95.74%), hepatobiliary lesions by ultrasound (97.87%), majority in right liver (90.32%), eosinophilia is the predominant indicator (90.42%), In the children group: the clinical manifestations included of epigastric and Chauffard-Rivet area pain (94.34%), flatuence, nausea and intermittent vomiting (76.41%), digestive disoders (40.57%), allergy (30.66%), fatigue plus weight loss (12.74%); laboratory findings included of hepatobiliary lesions by US (100%), positive ELISA with Fasciola gigantica antigen (96.70%), eosinophil of 93.39% and 1.90% positive copro-examination with Fasciolae eggs. Conclusions: In pregnant women, symptoms are indistinguishable from hepatobiliary, digestive tract diseases or overlap with gestation terrains, and clinical signs of paediatric fascioliasis may mimic a wide spectrum of hepatobiliary disorders laboratory parameters and imaging diagnostics, especially in FasELISA, hypereosinophilia and liver lesions by ultrasound were very useful in positive diagnosis.

This report describes two cases of feline hypertrophic osteopathy (HO) associated with congenital megaesophagus (ME). The diagnosis was based upon case history, physical examination, radiography and laboratory investigations. The clinical signs of both cats included; regurgitation, weakness and reluctance to walk since birth. Physical examination revealed painful and thickened long bones, swollen joints, difficult flexion of all four limbs and normal urination, defecation, appetite as well as heart and respiratory rates. The abnormal laboratory findings were thrombocytosis, leukocytosis with lymphocytosis and monocytosis. Survey and contrast thoracic radiography showed generalizedesophageal dilatation. Radiography of appendicular skeleton revealed symmetrical and massive subperiosteal new bone formation of the affected long bones and pelvis. In conclusion, radiography of extremities is highly recommended for cats admitted with congenital ME and lameness to investigate the possibility of HO. Moreover, the HO should be listed duringthe differential diagnosis of thickened limbs in cats.

Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system (CNS) with brain neurodegeneration. MS patients present heterogeneous clinical manifestations in which both genetic and environmental factors are involved. The diagnosis is very complex due to the high heterogeneity of the pathophysiology of the disease. The diagnostic criteria have been modified several times over the years. Basically, they include clinical symptoms, presence of typical lesions detected by magnetic resonance imaging (MRI), and laboratory findings. The analysis of cerebrospinal fluid (CSF) allows an evaluation of inflammatory processes circumscribed to the CNS and reflects changes in the immunological pattern due to the progression of the pathology, being fundamental in the diagnosis and monitoring of MS. The detection of the oligoclonal bands (OCBs) in both CSF and serum is recognized as the “gold standard” for laboratory diagnosis of MS, though presents analytical limitations. Indeed, current protocols for OCBs assay are time-consuming and require an operator-dependent interpretation. In recent years, the quantification of free light chain (FLC) in CSF has emerged to assist clinicians in the diagnosis of MS. This article reviews the current knowledge on CSF biomarkers used in the diagnosis of MS, in particular on the validated assays and on the alternative biomarkers of intrathecal synthesis.
