Equine Diseases

The course and outcome of a disease process is dependent upon factors such as the disease-causing agent and its cell tropism, defense mechanisms of the host, genetic resistance of the species or breed affected, as well as the age, nutritional status and hormonal levels of the affected animal. When haematology, clinical biochemistry and cytology test results are combined with other laboratory procedures, complete physical examination and also with the history of the patient, a veterinarian is well armed to arrive at a definitive diagnosis, make a certain prognosis (good, poor or guarded) and can also make a concluding statement on the efficacy of the instituted therapy. In clinical biochemistry, demonstration of specific enzyme activity and concentration of analytes in serum/plasma facilitates the disease diagnosis. Also, evaluation of haematology, clinical biochemistry and diagnostic cytology tests can help establish the presence or absence of diseases of internal organs, and by serial performance of these tests, may help to determine whether a disease process remains static, progressive or regressive. This review therefore provides the haematological, serum biochemical and cytological characteristics of diseases caused by the main bacteria, viruses, fungi, protozoa, helminths, arthropods, nutritional deficiencies, endocrine disturbances, neoplasm, allergy, toxins (phytoxins and zootoxins) and inorganic poisons in horses.

The proper use of prevalence and incidence data can result in an effective way to study the history of the disease process. Methodology is given whereby the progression, duration and transition of diseases can be elucidated. Prevalence and incidence have been redefined and used in an unconventional way in view of new types of data which are being generated by mass screening projects for disease which are able to discover presymptomatic and preclinical disease states.

Introduction: Intraorbital abscess is a rare complication of rhinosinusitis that affects most commonly the pediatric population. It is thought to be caused by direct extension or venous spread of infections from contiguous sites and can lead to life-threatening complications, like permanent visual loss and cerebral abscesses. Objectives: Intraorbital abscess is a rare condition that requires prompt diagnosis and treatment to avoid serious complications. Our objectives are to provide an overview of this rare disease process and its management including our successful treatment experience. Case Description: We present a 2 case report of a 13-year-old pediatric male and a 66-year-old male with history of chronic sinusitis who presented with a right intraorbital abscess successfully treated with external drainage with decompression of the orbit. Conclusion: When intraorbital abscess is encountered, a high index of suspicion is needed to allow prompt and accurate diagnosis for this infrequent condition. Timely surgical drainage of the abscess is needed to prevent the development of fatal complications.

ObjectiveTo investigate whether cerebrospinal fluid (CSF) ferritin (reporting brain iron) is associated with longitudinal changes in CSF β-amyloid (Aβ) and tau.MethodsMixed-effects models of CSF Aβ1-42 and tau were constructed using data from 296 participants who had baseline measurement of CSF ferritin and annual measurement of CSF tau and Aβ1-42 for up to 5 years.ResultsIn subjects with biomarker-confirmed Alzheimer’s pathology, high CSF ferritin (>6.2 ng/mL) was associated with accelerated depreciation of CSF Aβ1-42 (reporting increased plaque formation; p=0.0001). CSF ferritin was neither associated with changes in CSF tau in the same subjects, nor longitudinal changes in CSF tau or Aβ1-42 in subjects with low baseline pathology. In simulation modelling of the natural history of Aβ deposition, which we estimated to occur over 31.4 years, we predicted that it would take 12.6 years to reach the pathology threshold value of CSF Aβ from healthy normal levels, and this interval is not affected by CSF ferritin. CSF ferritin influences the fall in CSF Aβ over the next phase, where high CSF ferritin accelerated the transition from threshold preclinical Aβ levels to the average level of Alzheimer’s subjects from 18.8 to 10.8 years.ConclusionsIron might facilitate Aβ deposition in Alzheimer’s and accelerate the disease process.

Abstract We reviewed 127 patients who were operated upon for adult presentation Chiari malformation and made six conclusions: (a) The clinical examination remains crucial in the diagnosis. (b) The surgical anatomy is highly varied. (c) Syrinxes can be missed on preoperative contrast studies. (d By a conservative grading system, we determined that 46%; of the patients improved during long term follow-up. One-quarter deteriorated over the long run in spite of any treatment. (e) The overall results did not differ whether the treatment was plugging of the central canal plus decompression or decompression alone. (f) In patients with progression, plugging of the central canal obtained superior results. A review of the literature shows that the natural history of this complex disease process has not been established. This history is needed to identify the course of what may be several important factors that lead to the pathological condition in this disease.

Abstract Background: Lupus is an inflammatory and autoimmune disease that involves various tissues and organs of the body. Identification of diagnostic elements to rapid identification of seronegative lupus cases is very important in order to prevent morbidity and progression of disease. This study aimed to compare clinical and laboratory findings of seropositive cases with seronegative lupus patients. Methods: This cross-sectional analytic study was performed on 43 children (17 seronegative and 26 seropositive) with lupus who were admitted to Ali Asghar Hospital during 2007-2017. Seropositive patients had anti-nuclear antibody (ANA) titration >1/80, while seronegative patients had ANA titration <1/80 (at the time of disease diagnosis). Clinical and laboratory findings were compared between two groups.Results: Serositis in patients with ANA- was significantly higher than ANA+ (41.17% vs. 23.07%; p = 0.042). ANA- group had higher autoimmune disease history than ANA+ group (42.85% vs. 15.0%; p = 0.041). The family history of the disease in the ANA- group was greater than ANA+ group (50% vs. 23.52%). The percentage of hypertensive patients in ANA- group was higher than ANA+ group (52.94% vs. 26.92%; p = 0.037). Neurologic symptoms in ANA+ and ANA- groups were 38.46% and 17.64%, respectively (p = 0.043). The frequency of patients with thrombocytopenia in ANA+ group was significantly greater than ANA- group (32% vs. 12.5%; p=0.041). There was no significant difference in other clinical and laboratory findings between two groups. Conclusion: Seronegative lupus patients had higher percentage of musculoskeletal symptoms, autoimmune disease history, familial history of disease, and hypertension, while neurological and thrombocytopenia symptoms were higher in seropositive patients compared to seronegative cases. Therefore, evaluation of these factors can be helpful to diagnosis of seronegative patients.

ABSTRACTIntroduction:The relationship between Alzheimer’s Disease (AD) and alcohol addiction is poorly characterized. Arrests for driving under the influence (DUI) can serve as a proxy for alcohol addiction. Therefore, the potential association between DUI and AD could be helpful in understanding the relationship between alcohol abuse and AD.Materials and methods:A retrospective, population-based cohort study using state health and law enforcement data was performed. The study cross-referenced 141,281 South Carolina Alzheimer’s Disease Registry cases with state law enforcement data.Results:Of the 2,882 registry cases (1.4%) found to have a history of at least one DUI arrest, cases were predominantly White (58.7%) and male (77.4%). Results showed a correlation coefficient of 0.7 (p &lt; 0.0001) between the age of first DUI arrest and the age of AD diagnosis. A dose-response relationship between the number of DUIs and age of AD onset was found to exist, where those with a history of DUI arrest were diagnosed an average of 9.1 years earlier, with a further 1.8 years earlier age at diagnosis in those with two or more arrests for DUI. A history of DUI arrest was also found to be negatively associated with survival after diagnosis, with a 10% decreased life expectancy in those with a DUI arrest history.Conclusions:Driving under the influence, a potential indicator of alcohol addiction, is associated with an earlier onset of AD registry diagnosis and shortened survival after diagnosis. This study contributes to the growing body of evidence suggesting that some cases of AD are alcohol related and, possibly, postponable or preventable.

Whole genome sequencing (WGS) is a very valuable resource to understand the evolutionary history of poorly known species. However, in organisms with large genomes, as most amphibians, WGS is still excessively challenging and transcriptome sequencing (RNA-seq) represents a cost-effective tool to explore genome-wide variability. Non-model organisms do not usually have a reference genome and the transcriptome must be assembledde-novo. We used RNA-seq to obtain the transcriptomic profile forOreobates cruralis, a poorly known South American direct-developing frog. In total, 550,871 transcripts were assembled, corresponding to 422,999 putative genes. Of those, we identified 23,500, 37,349, 38,120 and 45,885 genes present in the Pfam, EggNOG, KEGG and GO databases, respectively. Interestingly, our results suggested that genes related to immune system and defense mechanisms are abundant in the transcriptome ofO. cruralis. We also present a pipeline to assist with pre-processing, assembling, evaluating and functionally annotating ade-novotranscriptome from RNA-seq data of non-model organisms. Our pipeline guides the inexperienced user in an intuitive way through all the necessary steps to buildde-novotranscriptome assemblies using readily available software and is freely available at:https://github.com/biomendi/TRANSCRIPTOME-ASSEMBLY-PIPELINE/wiki.

Objectives: The objectives of the study were to characterize the clinical profile of childhood leprosy presenting at tertiary leprosy care hospitals in the states of Bihar, West Bengal and Uttar Pradesh in India, and to determine the possible risk factors associated with disabilities at presentation. Methods: Subjects were children with newly diagnosed leprosy registered for treatment at tertiary Leprosy Mission Hospitals in Muzaffarpur (Bihar), Purulia (West Bengal) and Faizabad (Uttar Pradesh), India, between June and December 2019. Demographic and leprosy characteristics were collected at the time of diagnosis. Parents/guardians were interviewed on reasons for delay in presenting at the hospital. Associations between various factors and delay in diagnosis were assessed. Results: Among the 84 children, the mean (SD) age was 10 (3) years with a range of 4–14 years. There were more boys (58%) and most children were currently in school (93%), resident in rural areas (90%) and belonged to a lower socioeconomic status (68%). More children were diagnosed with multibacillary leprosy (69%), one-third of them being skin smear positive for Mycobacterium leprae. On presentation, 17% had deformity (5% grade 1 deformity and 12% grade 2), 29% had nerve involvement and skin lesions were spread across the body in half of the children. Mean (SD) duration of delay was 10.5 (9.8) months. Delayed presentation was more in boys (43% vs. 17%; P = 0.01), those without a history of migration for work compared to those who had a history of migration (40% vs. 9%; P = 0.008) and in those children who were from a poor economic status compared with those that came from a better economic status (44% vs. 7%; P = 0.001) Limitations: Because our study was conducted at tertiary care hospitals, the findings are not representative of the situation in the field. Furthermore, a comparison group of newly diagnosed adult leprosy patients with disability could have been included in the study. Conclusion: Childhood leprosy continues to occur in endemic pockets in India and a substantial number present with skin smear positivity and deformity. Guardians of these children cite many reasons for the delay in presentation.

Diagnosis in Ayurveda is not always in terms of the name of the disease but in terms of the nature or phenomenon. This phenomenon is described in terms of Samprapti of the disease in each patient, comprising Dosha, Dushya and Adhishtana components. The prime factors in the pathogenesis of the disease are Dosha and Dushya. Shat kriyakala refers to the stage of development of a pathological process in which a physician can intervene by the most accurate treatment modality and medicine, thereby halting the progression of the disease process. By intricate understanding of the process of Shat kriyakala, the disease process could be arrested, and further complications can be avoided. In the current scenario, the concept of prevention has become broad-based. The natural history of disease is one of the significant elements of epidemiology. The course of a disease takes in individual people from its pathological onset until its eventual resolution. Natural history of disease is possible to correlate pre-pathogenesis with Sanchaya, Prakopa, Prasara and pathogenesis with Sthanasamsraya, Vyakti and Bhedavastha of Shat kriyakala. Recent studies have shown that it is possible to identify certain pre-clinical stages for many diseases like Parkinson’s disease, which can help in the early successful treatment. Shat kriyakala helps to arrest the disease process at the very early stage itself. Along with current technology, the need for research for validating the Shat kriyakala will benefit humankind in the long run.

Occam's Razor

Abstract Objectives Our discussant’s thoughtful consideration of the patient’s case allows for review of three maxims of medicine: Occam’s razor (the simplest diagnosis is the most likely to be correct), Hickam’s dictum (multiple disease entities are more likely than one), and Crabtree’s bludgeon (the tendency to make data fit to an explanation we hold dear). Case presentation A 66-year-old woman with a history of hypertension presented to our hospital one day after arrival to the United States from Guinea with chronic daily vomiting, unintentional weight loss and progressive shoulder pain. Her labs are notable for renal failure, nephrotic range proteinuria and normocytic anemia while her shoulder X-ray shows osseous resorption in the lateral right clavicle. Multiple myeloma became the team’s working diagnosis; however, a subsequent shoulder biopsy was consistent with follicular thyroid carcinoma. Imaging suggested the patient’s renal failure was more likely a result of a chronic, unrelated process. Conclusions It is tempting to bludgeon diagnostic possibilities into Occam’s razor. Presumption that a patient’s signs and symptoms are connected by one disease process often puts us at a cognitive advantage. However, atypical presentations, multiple disease processes, and unique populations often lend themselves more to Hickam’s dictum than to Occam’s razor. Diagnostic aids include performing a metacognitive checklist, engaging analytic thinking, and acknowledging the imperfections of these axioms.
