Acute Respiratory Viral Infection

COVID−19 is an acute respiratory viral disease caused by the RNA virus of the SARS−CoV−2 (2019 nCoV) coronavirus family and can have both mild course in the form of acute respiratory viral infection and severe one with frequent complications such as pneumonia, thrombosis, cerebrovascular disorders and high mortality. Hypoxia of the brain and spinal cord is associated with impaired gas exchange in the pulmonary alveoli, progressive respiratory failure with subsequent decompensation of function and structural damage to all organs and systems. Neurological disorders in COVID−19, observed in almost a half of patients, can be divided into three groups: manifestations of the central nervous system, lesions of the peripheral nervous system, myopathy. In order to study the lesion of the nervous system in patients with COVID−19, a history of acute cerebrovascular disorders and clinical picture of stroke without the emergence of new foci in neuroimaging, three clinical cases were analyzed. All patients complained of speech impairment, disorientation in time and space, numbness and weakness in the extremities on the background of acute cerebrovascular accident in the anamnesis, accompanied by general weakness and fever to subfebrile figures. COVID−19 pneumonia was observed during computed tomography of the lungs. However, during neuroimaging new foci of infarction were not identified. Thus, given the lack of new foci of infarction during neuroimaging, lack of hypercoagulation and cardiac causes, it can be concluded that focal symptoms in patients with COVID−19 with a history of stroke cause hypoxia of brain cells in the area around the necrotic foci resulted from previous heart attacks. Key words: nervous system, lesions, COVID−19, coronaviruses, encephalopathy, hypoxia.

The new coronavirus SARS-CoV-2 is a single-stranded RNA virus of the Coronaviridae family and is clinically manifest with respiratory symptoms. However, patients have been described with symptoms and complications from the nervous system, as well as skin manifestations in the form of various rashes. In our clinical case of coronavirus infection (SARS-CoV-2), this is pneumonia with respiratory failure of the 1st degree, moderate severity and Bell’s palsy in combination with skin rashes in the form of an urticarial rash in a 58-year-old woman. Clinical features of cutaneous and neurological symptoms were prior to the development of respiratory symptoms. The presented clinical case showed that COVID-19, before the development of respiratory symptoms, can manifest itself with peripheral paralysis of the facial nerve and be combined with skin rashes, which can complicate the timely diagnosis of a viral disease.

Introduction: Newcastle disease (ND) is a viral disease of birds caused by a negative sense single-stranded RNA virus known as the Newcastle disease virus. It is a disease of almost all species of domestic and wild birds with devastating impacts on poultry health and production. The aim of this study was to determine the prevalence of ND within species, breeds, age and vaccination history from the period of 2014-2018. Methods: A five- year retrospective study (2014-2018) of cases of poultry diseases diagnosed at the Avian Clinic of Veterinary Teaching Hospital (VTH), Ahmadu Bello University (A.B.U), Zaria, Nigeria was conducted, the prevalence of ND within species, breeds, age and vaccination history was determined. Case records file were collected, studied, and clinically diagnosed cases of ND were extracted. Results: It was observed that of the 1,768 poultry cases presented, 754 (42.6%) were confirmed as ND. Most cases were recorded in chickens 710 (40.2%). The prevalence was highest in the improved breed 670 (37.9%) while the local and unknown breeds had prevalence of 4 (0.2%) and 80 (4.5%) respectively. Birds within 8-13 weeks of age had the highest prevalence of 276 (15.4%) while the lowest prevalence of 19 (1.1%) was recorded in birds of unknown ages. Birds with history of incomplete vaccination (single vaccination) had the highest prevalence of 232 (13.1%), while those with complete vaccination history (three rounds of vaccination) had the lowest prevalence of 50 (2.8%). Significance: Poor management practices and improper knowledge of vaccination by the poultry handlers may be responsible for the prevalence pattern of ND recorded. Adequate biosecurity measures and routine vaccination are recommended to minimize the outbreak of ND.

Abstract Background To report a case of acute exudative polymorphous paraneoplastic vitelliform maculopathy in a patient with a history of choroidal melanoma, with metastases to the pancreas, liver, and central nervous system. Case presentation A 63-year-old patient, with a history of enucleation of the right eye due to choroidal melanoma, complained of progressive visual loss during a follow-up visit. Fundoscopic examination revealed multiple small areas of serous retinal detachment scattered throughout the posterior pole and ancillary tests confirmed the diagnosis of acute exudative polymorphous paraneoplastic vitelliform maculopathy (AEPPVM). Screening for systemic metastases showed pancreatic, hepatic, and central nervous system involvement. Conclusions We describe a rare case of acute exudative polymorphous paraneoplastic vitelliform maculopathy, which should be considered in patients with or without a history of melanoma, who have vitelliform retinal detachments. Nevertheless, no previous reviews of literature have shown a correlation between AEPPVM and pancreatic metastasis.

Insight Into

Establishing accurate symptomatology associated with novel diseases such as COVID-19 is a crucial component of early identification and screening. This case report identifies an adult patient with a history of clotting dysfunction presenting with rare cutaneous manifestations of COVID-19, known as ‘COVID-19 toes’', previously described predominantly in children. Additionally, this patient presented with possible COVID-associated muscle spasticity of the lower limbs, as well as a prolonged and atypical timeline of COVID-19 infection. The rare occurrence of ‘COVID-19 toes’' in this adult patient suggests that her medical history could have predisposed her to this symptom. This supports the coagulopathic hypothesis of this manifestation of COVID-19 and provides possible screening questions for patients with a similar history who might be exposed to the virus. Additionally, nervous system complaints associated with this disease are rare and understudied, so this novel symptom may also provide insight into this aspect of SARS-CoV-2.

1. The family histories of 722 infants who were born with spina bifida cystica were studied. 2. The index cases were referred for surgical treatment and were not selected in any way from the genetic point of view. 3. Intensive inquiries were made to obtain a complete family pedigree, including a prospective follow-up of siblings born after the index case. 4. Of 1,256 siblings 85 or 6.8% had gross malformation of the central nervous system: spina bifida cystica in 54, anencephaly in 22, and uncomplicated hydrocephalus in 9. 5. Of 306 children born after the index case 25 (8%) or 1 in 12 were affected. 6. There was a progressive increase in multiple cases in the family with increasing family size. In sibships of five or more, multiple cases occurred in 24.1%. 7. In 118 families cases of gross malformation of the central nervous system were known to have occurred among members of the family other than siblings. Cases occurred in three generations. 8. It is possible that spina bifida cystica might be a recessively inherited condition.

Nervous system involvement in Lyme disease was originally described as meningitis, cranial neuritis, and radiculoneuritis,1-3 but Lyme disease can also involve the brain parenchyma. We describe a child whose first manifestation of Lyme disease was an acute, focal meningoencephalitis with signs and symptoms such as fever, headache, slurred speech, hemiparesis, seizure, and CSF pleocytosis. CASE REPORT A 7-year-old boy was hospitalized Aug 27, 1985, because of hemiparesis. Six weeks prior to admission he had vacationed at Old Lyme, CT. There was no history of rash or tick bite. He had been well until eight hours prior to admission when fever and headache developed.

Central Nervous System Toxicity

A 26-year-old male with a history of pre-B cell acute lymphoblastic leukemia and seizures presented with second relapse of acute lymphoblastic leukemia and central nervous system involvement, 19 years after the initial diagnosis. Over the next two months, the patient received six doses of triple intrathecal chemotherapy (cytarabine, methotrexate, and hydrocortisone), three concurrently with continuous blinatumomab in the second month. Approximately 12 days after blinatumomab initiation, he developed central nervous system toxicity manifesting as speech impairment, altered mental status, incontinence, and diffuse weakness. Blinatumomab was discontinued, and he was started on dexamethasone. Within the next couple of months, his neurologic status recovered, and he was able to perform all of his baseline activities without limitation. Unfortunately, the patient eventually expired after further relapse approximately one year later. To our knowledge, this is the first published case report of severe neurotoxicity in a patient who was given blinatumomab concurrently with intrathecal chemotherapy.

The main object of the present paper is to furnish a brief account to the knowledgement of Protozoa parasitic in common Brazilian frog of the genus Leptodactylus for general students in Zoology and for investigators that use this frog as a laboratory animal. Hepatozoon leptodactyli (Haemogregarina leptodactyli) was found in two species of frogs - Leptodactylus ocellatus and L. pentadactylus - in which develop schizogony whereas sporogony occurs in the leech Haementeria lutzi as was obtainded in experimental conditions. Intracellular forms have been found in peripheral circulation, chiefly in erythrocytes, but we have found them in leukocytes too. Tissue stages were found in frog, liver, lungs, spleen, gut, brain and heart. The occurence of hemogregarine in the Central Nervous System was recorded by Costa & al,(13) and Ball (2). Some cytochemical methods were employed in attempt to differentiate gametocytes from trophozoites in the peripheral blood and to characterize the cystic membrane as well. The speorogonic cycle was developed in only one specie of leech. A brief description of the parasite is given.

Abstract Background: Infantile neuroaxonal dystrophy (INAD) is a rapidly progressive neurodegenerative disorder of early onset causing premature death. It results from biallelic pathogenic variants in PLA2G6, which encodes a calcium‐independent phospholipase A2. Objective: We aim to outline the natural history of INAD and provide a comprehensive description of its clinical, radiological, laboratory, and molecular findings. Materials and Methods: We comprehensively analyzed the charts of 28 patients: 16 patients from Riyadh, Saudi Arabia, 8 patients from North and South America and 4 patients from Europe with a molecularly confirmed diagnosis of PLA2G6‐associated neurodegeneration (PLAN) and a clinical history consistent with INAD.Results: In our cohort, speech impairment and loss of gross motor milestones were the earliest signs of the disease. As the disease progressed, loss of fine motor milestones and bulbar dysfunction were observed. Temporo-frontal function was among the last of the milestones to be lost. Appendicular spastic hypertonia, axial hypotonia, and hyperreflexia were common neurological findings. Other common clinical findings include nystagmus (60.7%), seizures (42.9%), gastrointestinal disease (42.9%), skeletal deformities (35.7%), and strabismus (28.6%). Cerebellar atrophy and elevations in serum AST and LDH levels were consistent features of INAD. There was a statistically significant difference when comparing patients with non-sense/truncating variants compared with missense/in-frame deletions in the time of initial concern (p = 0.04), initial loss of language (p = 0.001), initial loss of fine motor skills (p = 0.009), and initial loss of bulbar skills (p = 0.007).Conclusion: INAD is an ultra-rare neurodegenerative disorder that presents in early childhood, with a relentlessly progressive clinical course. Knowledge of the natural history of INAD may serve as a resource for healthcare providers to develop a targeted care plan and may facilitate the design of clinical trials to treat this disease.
