AbstractThe clinical and pathological findings of a case of fatal disseminated toxoplasmosis in a captive brown-throated sloth (Bradypus variegatus) from the northern region of Brazil are reported. Clinical signs were nonspecific and included apathy, prostration, dyspnoea, and loss of appetite. Treatment with penicillin was attempted, but the animal died within five days of the onset of clinical signs. Microscopically, there was acute inflammation in the liver, spleen, and lungs associated with necrosis and a few cysts and extracytoplasmic tachyzoites, with a morphology compatible with Toxoplasma gondii. Tissue sections were submitted for immunohistochemistry that confirmed T. gondii as the aetiological agent. To the authors’ knowledge, this is the first report of toxoplasmosis in B. variegatus.

Pyometra in felines may present with a vaginal discharge or no vaginal discharge, depending on the opening of the uterine cervix. The most obvious clinical signs of a closed uterine cervix pyometra are loss of appetite, apathy, lethargy, polydipsia, polyuria, hyperthermia and abdominal enlargement. The veterinary approach depends on numerous factors, but the patient is invariably submitted to an ovariohysterectomy. This case report discusses a puma (Puma concolor), aged over 16 years and under human care in a zoo in the state of São Paulo, Brazil, with clinical suspicion of closed pyometra. The patient underwent ultrasound examination, laboratory analysis and an ovariohysterectomy. The animal recovered well and returned to the display enclosure at the zoo.

Brain Anomaly

This case report describes the clinical signs, magnetic resonance imaging (MRI) findings and associated (histo)pathological findings in a crossbred Belgian Blue calf with congenital complex brain anomaly. The calf was presented with non-progressive signs (including cerebellar ataxia) since it was born, suggestive of a multifocal intracranial lesion. A congenital anomaly was suspected and after hematology, biochemistry, serology, and cerebrospinal fluid analysis, a magnetic resonance imaging study was performed. The following suspected abnormalities were the principal changes identified: severe hydrocephalus, porencephaly, suspected partial corpus callosum agenesis (CCA), and increased fluid signal between the folia of the cerebellum. Post-mortem examination predominately reflected the MRI findings. The origin for these malformations could not be identified and there was no evidence of a causative infectious agent. Corpus callosum abnormalities have been reported in bovids before and have been linked to bovine viral diarrhea virus (BVDV) infections, as have several other central nervous system anomalies in this species. In this case, BVDV was deemed an unlikely causative agent based on serology test results and lack of typical histopathological signs. The etiology of the congenital anomaly present in this bovine calf remains unknown.

Oesophageal disorders are relatively uncommon in large animals. Oesophageal obstruction is the most frequently encountered clinical presentation in bovine and it may be intraluminal or extra luminal (Haven, 1990). Intraluminal obstruction or “choke” is the most common abnormality that usually occurs when foreign objects, large feedstuff, medicated boluses, trichobezoars, or oesophageal granuloma lodge in the lumen of the oesophagus. Oesophageal obstructions in bovine commonly occur at the pharynx, the cranial aspect of the cervical oesophagus, the thoracic inlet, or the base of the heart (Choudhary et al., 2010). Diagnosis of such problem depends on the history of eating particular foodstuff and clinical signs as bloat, tenesmus, retching, and salivation

AbstractNocardia brain abscess is a rare clinical entity, accounting for 2% of all brain abscesses, associated with high morbidity and a mortality rate 3 times higher than brain abscesses caused by other bacteria. Proper investigation and treatment, characterized by a long-term antibiotic therapy, play an important role on the outcome of the patient. The authors describe a case of a patient without neurological comorbidities who developed clinical signs of right occipital lobe impairment and seizures, whose investigation demonstrated brain abscess caused by Nocardia spp. The patient was treated surgically followed by antibiotic therapy with a great outcome after 1 year of follow-up.

Abstract Background Clinical signs of heat in bitches that have been previously spayed are often associated with the presence of ovarian remnant syndrome. The inclusion of exogenous estrogens as a differential diagnosis in this regard is often ignored and may lead to misinterpretation of the case. Case presentation Herein, we report a case of exogenous estrogen exposure over several months to a 6.5-year-old spayed crossbred bitch, weighing 8.4 kg. The bitch presented in the clinic because of suspected ovarian remnant syndrome. Castration was performed within the first 6 months after birth. Important endocrine parameters measured at the first appointment were Anti-Müllerian hormone (< 0.01 ng/mL), progesterone (0.36 ng/mL), estradiol-17ß (20.7 pg/mL), and luteinizing hormone (< 0.1 ng/mL). After an extensive conversation with the owner, it was revealed that she was using an estrogen spray because of severe menopausal symptoms. After the owner stopped using this spray, the symptoms of the bitch disappeared. Conclusion Therefore, the uptake of estrogens should be a differential diagnosis for symptoms of the ovarian remnant syndrome. A detailed anamnesis is crucial to identify the source of estrogen in the environment of the affected bitch.

Abstract Yttrium-90 (Y-90) trans-arterial radioembolization (TARE) is used in the management of unresectable hepatocellular carcinoma (HCC). During the last 5 years, dosimetry software has been developed to allow for a more rigorous approach of dose prescription in Y-90 TARE. We present here a case study of a 77-year-old woman diagnosed with HCC, who underwent a Y-90 TARE as a bridge procedure to liver resection. This clinical scenario represents a unique opportunity to illustrate the predictive value of dosimetric findings correlating dosimetry with pathological findings. In this case, Y-90 TARE dosimetry was predictive of treatment response in which the tumor received a mean dose of 156 Gy and demonstrated a complete pathologic response.

ABSTRACT Introduction The diagnosis of traumatic brain injuries is typically based on hemispheric blasts resulting in degrees of unconsciousness and associated cerebral injuries. This case report describes a Vietnam War era setting in which a traumatic blast wave struck the posterior cranium in the region of the foramen magnum, occipital crest, and other skull openings (orbit, oronasal, and ear) and the unique secondary clinical signs and symptoms experienced over time. Materials and Methods This case report describes secondary delayed-onset clinical signs and symptoms consistent with progressive decades-long physical and functional complications. The traumatic blast resulted in brief unconsciousness, decreased vision in left eye, confusion, right sided hemotympanum, deafness, severe tinnitus, severe nasopharynx pain and difficulty swallowing, pain in right posterior and occipital area of the head, and loss of dental amalgams. Subsequent exams revealed progressive hyperacusis, sea sickness, dysdiadochokinesis, diagnosis of 9th and 10th cranial nerve traumatic schwannomas, hyperdense changes to the frontal lobe white matter, progressive tinnitus, chronic vertigo, right-sided high-frequency hearing loss, progressive oculo-gyric crisis of Tumarkin-like seizures, left-sided chronic vitreous hemorrhage, and diminished right hemisphere performance of the brain based on neurophysiological assessment. No post-traumatic stress, depression, or other emotional or psychiatric difficulties were claimed. Conclusion This case report, unique to the English language scientific literature, discusses in detail the secondary signs and symptoms of a foramen magnum and occipital crest focused-associated blast injury.

Markesbery-Griggs myopathy, Miyoshi type (MM) is a rare type of myopathy, a form muscular dystrophy with the main involvement of the lower girdle and distal parts of the legs. Due to complexity of genetic testing, the diagnosis is mainly made on the neurological examination of the patient, which adds value to this case report. The childhood or adolescence onset of the disease is characterized initially by the calf muscles` wasting, accompanied by the severe elevation of the serum creatine kinase, as well as a slowly progressive ascending course. The disease refers to dysferlinopathies with various mutations in the DYSF gene. The dysferlin protein is localized in the plasma membrane and in the T-tubule system of skeletal muscles. Physiologically, skeletal muscles are constantly exposed to micromembrane lesions. Depending on the severity, these damages are restored using various complexes. One of the main reparative complexes is the dysferlin-dependent mechanism. Mutations can lead to a defect in the membrane repair, causing the influx of Ca 2+ into the cell, which leads to a cell`s destruction. There are three genetically identifiable types of Miyoshi myopathy: MMD1, MMD2, MMD3. The main clinical signs of the disease are the muscle weakness and atrophy, with predominant involvement of the distal parts of the lower limbs, especially in the gastrocnemius and plantar muscles. The MM causes tip toe walking disturbances and difficulties in climbing the stairs. Progression of the disease and further atrophy leads to the wasting of the lower girdle muscles, mainly gluteal ones. Peculiarity of these myopathies is the absence of cardiomyopathy, due to the immunity of cardiomyocytes to a deficiency of the protein dysferelin. Diagnosis is made on the basis of muscle biopsy and molecular genetic testing. The gold standard is immunoblotting or immunohistochemistry. One of treatment methods is the use of improperly folded dysferlin (treatment with a proteasome inhibitor MG-132) in fibroblasts with restoration of membrane sealing. The aim of this case report is to present an example of a possible clinical diagnosis of MM in a young man, in the absence of opportunities for molecular genetic testing.

The case report demonstrates the issue of Khalid Ali, who is a citizen of Yamen, explicitly living in Saudi Arabia. He is 38 years, weighs 82kgs, and of 162 cm in height. He is a sales professional and married with two kids. Khalid Ali has been living healthy until two years ago when he started experiencing pains in his lower extremities accompanied by numbness. He was treated, and everything went back to normal until soon when the case came back after the administration of the Pfizer vaccine as a preventive measure for COVID-19 disease. The consequence of the administration of the Pfizer vaccine resulted in severe pain and weaknesses in his legs and severe headache on the second day, which resulted in him being put on an ICU after 48 hours since he was almost paralyzed. A series of tests were conducted on him, including magnetic resonance imaging (MRI), hematology, and biochemistry which involved Cerebrospinal Fluid (CSF) protein test. MRI findings were significant since they indicated acute inflammation on the spine observed on the dorsal spinal cord with contrast and lumbosacral spinal cord. All the hematology tests turned out to be expected. Biochemistry conducted tests were similarly standard except for CSF protein which was highly abnormal. The combination of the high abnormal CSF protein test and acute inflammation of the spine observed from the MRI findings were confirmed evidence of acute transverse myelitis as a result of the administration of the Pfizer vaccine.
