Case summary A 3-year-7-month-old female neutered domestic shorthair cat was presented for further investigation of acute-onset neurological abnormalities, including marked decreased mentation, ataxia and abnormal cranial nerve responses, with concurrent marked pyrexia (40ºC). Initial blood testing was non-specific with mild-to-moderate increases in alanine aminotransferase (ALT) (194 IU/l; reference interval [RI] 17–62 IU/l), aspartate aminotransferase (AST; 150 IU/l [RI 0–51 IU/l]) and total bilirubin (20 µmol/l; RI 0–11 µmol/l), and neutropenia (1.17 ×109/l; RI 2.5–12.5 ×109/l). Brain MRI and cerebrospinal fluid analysis were unremarkable and Toxoplasma serology was negative. Worsening of hepatic biochemical parameters (ALT 265 IU/l, AST 205 IU/l, total bilirubin 42.9 µmol/l) led to further investigations for liver disease, including ultrasound, fine-needle aspirate cytology, histology, fluorescent in situ hybridisation and culture of liver tissue and bile, resulting in a diagnosis of Yersinia pseudotuberculosis hepatitis. The cat was treated with a combination of potentiated amoxicillin (62.5 mg PO q12h), marbofloxacin (5mg PO q24h) and combined s-adenosyl methionine (SAMe)/silybin (90 mg PO q24h), and made a full recovery. Follow-up over 14 months identified a persistent mild increase in ALT, despite no apparent ongoing disease. Relevance and novel information Yersinia pseudotuberculosis hepatitis should be considered as a differential diagnosis in cats presenting with acute-onset neurological signs, and, when diagnosed, can be successfully treated with a combination of marbofloxacin, potentiated amoxicillin and SAMe/silybin. This is the first such case treated successfully with licensed veterinary antimicrobials and the first instance where Y pseudotuberculosis hepatitis has presented with primarily neurological clinical signs.

Distressing Condition

A 76-year-old man was admitted to the hospital with acute onset of involuntary movements of the left side of his body. His neurological examination revealed he was oriented only to himself, and aforementioned movements of his left arm and leg. CT head demonstrated old infarcts in his right aspect of his pons and basal ganglia. Cerebrospinal fluid analysis was unremarkable. He initially had a normal blood glucose with an elevated anion gap and elevated creatine kinase. Brain MRI showed a small lacunar-type ischaemic infarct within the anteromedial aspect of the right cerebral peduncle, which localised to his haemiballism. To prevent worsening rhabdomyolysis associated with his haemiballism, the primary team initiated both tetrabenazine and diazepam. His movements improved after 1 week of medication therapy. This report discusses a thorough workup for this movement disorder and when to intervene for this distressing condition.

A 3-year-old, spayed female rat terrier was evaluated for acute onset of stupor, disorientation, and tetraparesis. Clinical signs progressed over 3 weeks to eventual right-sided hemiparesis and circling to the left. A Cuterebra spp. larva was discovered in the vomitus of the dog 2 weeks after the onset of clinical signs. Cerebrospinal fluid analysis showed chronic inflammation, and magnetic resonance imaging supported a diagnosis of a parasitic tract through the left cerebral hemisphere. Medical management included a tapering anti-inflammatory dose of prednisone. Clinical signs improved slowly over time. This is the first description of a presumptive antemortem diagnosis of canine cuterebrosis in the central nervous system.

Reversible Encephalopathy

A 71-year-old woman presented to the emergency room with dysphonia, diplopia, dysphagia and generalised weakness since that day. Neurological examination revealed eye adduction limitation, ptosis, hypoactive reflexes and gait ataxia. Blood and cerebrospinal fluid analysis and brain CT were normal. Electromyography revealed a sensory axonal polyneuropathy. She was diagnosed with Miller-Fisher syndrome (MFS) and started on intravenous immunoglobulin. Two days after intravenous immunoglobulin treatment was completed, she developed a sustained hypertensive profile and presented a generalised tonic-clonic seizure. Brain MRI was suggestive of posterior reversible encephalopathy syndrome (PRES) and supportive treatment was implemented with progressive improvement. PRES may be a possible complication of MFS not only due to autonomic and inflammatory dysfunctions, but also as a consequence of its treatment. Patients with MFS should be maintained under close surveillance, especially in the first days and preferably in intermediate care units.

During a strangles outbreak within a herd of minature horses, a six week old foal developed acute onset clinical signs of sepsis and neurological deficits. The foal was euthanized and submitted for post-mortem at the Animal Health Laboratories, Guelph Ontario. Gross <em>post-mortem</em> examination noted severe bronchopneumonia, hypopyon of the right eye and a singular cerebellar peduncle abscess. Culture of the lungs and cerebellum produced a pure growth of <em>Streptococcus equi</em> ssp. <em>equi</em>. <em>Streptococcus equi</em> ssp. <em>equi</em>, the causative agent of equine strangles, produces an acute pyrexia, purulent lymphadenopathy of submandibular and retropharyngeal lymph nodes. Commonly, lymph node abscesses rupture and resolve without complication. Rarely, complications may include: dissemination of the bacteria with diffuse abscess formation, immune mediated disease (purpura haemorrhagica), rarely abscess formation within the central nervous system (CNS) can occur. These can be managed medically with appropriate antibiotics and drugs to reduce intra-cranial pressure, however surgical drainage and debulking of the abscess has been attempted successfully in a few cases.

Schirmer Tear Test

Objectives The aim of this study was to describe the clinical findings, diagnostic test results and response to therapy of cats with Schirmer tear test 1 (STT-1) values below the reference interval. Methods The medical records of three institutions were searched for cats with ocular surface disease and STT-1 values <9 mm/min, confirmed at two or more separate visits. Results Ten cats (17 eyes) were included. The mean ± SD (range) age and STT-1 values in affected eye(s) were 6.1 ± 5.7 (0.2–16) years and 2.4 ± 3.1 (0–8) mm/min, respectively. Concurrent ocular surface disease was bilateral in 5/10 cats. Clinical signs included conjunctivitis (14/17 eyes), corneal ulceration (6/17 eyes), non-ulcerative keratitis (4/17 eyes), symblepharon (4/17 eyes), eosinophilic keratitis (3/17 eyes), corneal sequestrum (3/17 eyes), corneal fibrosis (2/17 eyes) and meibomitis (2/17 eyes). Management included: topically applied lacrimomimetics, antiviral drugs, corticosteroids or immunomodulatory drugs; orally administered famciclovir; or surgical procedures, in various combinations. Response to therapy (defined as an increase in STT-1 value of ⩾5 mm/min) was transient (seen at a single reassessment) in 65% of eyes and sustained (seen at ⩾2 consecutive reassessments) in 18% of eyes. Conclusions and relevance Clinical features seen in cats with low STT-1 values are described, although the association between aqueous deficiency and the reported ocular changes is unknown at this time. We encourage clinicians to assess the tear film in cats with ocular surface disease, and initiate therapy with lacrimomimetics if STT-1 values are repeatedly below normal. Such information will further define aqueous tear deficiency in cats, providing a better understanding of disease prevalence, pathogenesis and treatment.

Introduction. COVID-19 is associated with a significant incidence of bacterial and fungal superinfections and with the exacerbation of pre-existing infections, representing a diagnostic and therapeutic challenge. Case presentation. A 64-year-old woman, confirmed with COVID-19 by the SARS-CoV-2 antigen test, is hospitalized accusing fatigue, nausea, watery stools, cough and vertigo started 10 days ago, aggravated 4 days before the presentation. It also reports recurrent episodes of otalgia and otorrheic pluriantibiotic treatment in the last 2 months. From the personal pathological antecedents we remember: hypothyroidism, dyslipidemia, hypertension, ischemic heart disease, history of deep vein thrombosis (DVT) and secondary pulmonary thromboembolism, in chronic anticoagulant treatment. Pathological clinical signs at admission: bilateral basal crackling rales. Biologically, inflammatory syndrome is detected, and radiologically, interstitial-alveolar infiltrates in the lower lung fields. On day 3 of hospitalization, the patient shows purulent secretion in the right external auditory canal and the ENT consultation confirms chronic suppurative otitis media in acute onset. Bacteriological examination of otic secretion reveals Aspergillus niger. Antiviral treatment with Remdesivir is initiated, antibiotic therapy initiated at home with Azithromycin is continued for one day, then escalated to Ceftriaxone i.v. (in the context of clinical-paraclinical aggravation), systemic corticotherapy, anticoagulation with Dalteparin in the prophylactic regime of DVT, systemic treatment with Voriconazole p.o. (according to the antifungal program) and topical (local) with a slow favorable evolution. Conclusions. The association of COVID-19 with otitis with Aspergillus is a rare and particular clinical picture.

Abstract Background Currently, myelin oligodendrocyte glycoprotein (MOG)-IgG-associated encephalomyelitis (MOG-EM) is regarded as an independent inflammatory demyelinating disease. Magnetic resonance imaging (MRI) abnormalities occur in 44.4% of patients with MOG-EM. However, symmetrical deep gray matter involvement with leptomeningeal enhancement is rarely described in the literature. Case presentation A 3-year-old boy was admitted to our hospital because of acute onset fever, headache, vomiting and disturbance of consciousness. Neurological examination showed somnolence, neck stiffness and positive Kernig’s sign. Brain MRI demonstrated bilateral symmetrical lesions in the basal ganglia and thalamus as well as diffuse leptomeningeal enhancement along the sulci of bilateral hemisphere. Cerebrospinal fluid analysis demonstrated increased cell count (7 cells/mm3, mononuclear cells dominant) and protein (1.17 g/L) without glucose and chloride abnormality. Work-up for infectious and autoimmune causes, serum MOG IgG was positive by cell based assay. Therefore, a diagnosis of MOG-EM was established according to the international recommendatory criteria in 2018. He was administrated with intravenous methylprednisolone followed by oral corticosteroids and had recovered completely within 1 week. Conclusions In the setting of meningoencephalitis-like clinical presentation with bilateral symmetrical deep gray matter involvement, MOG-EM should be distinguished from other infectious and autoimmune disorders, such as Epstein-Barr virus (EBV) encephalitis, Japanese encephalitis and Anti-NMDA receptor (NMDAR) encephalitis. Besides, aseptic meningitis associated with leptomeningeal enhancement may be an atypical phenotype of MOG-EM.

Patient’S History

A 5-month-old male intact Great Pyrenees was presented for an acute onset of severe neurologic signs (stupor, absent menace, intermittent head turn to the left). The patient's history included possible naproxen ingestion with a maximum ingested dose of 59 mg/kg, exceeding the reported dose of &gt;50 mg/kg known to cause neurologic signs. Blood sampling for baseline bloodwork was performed, and intravenous lipid emulsion (ILE) was subsequently administered, for treatment of the suspected toxicosis. Due to severe and life-threatening neurologic signs, other methods of decontamination were contraindicated and unlikely to be effective; extracorporeal therapy was also unavailable. Complete resolution of neurologic signs occurred 30 min after completion of ILE therapy. At this time, the owners found the missing naproxen tablets after returning home and the bloodwork results returned revealing findings consistent with hepatic encephalopathy. The fasted blood ammonia concentration immediately prior to ILE administration was 702.1 μg/dL (reference interval, RI: 24–36 μg/dL) and decreased to 194.1 μg/dL 24 h later. In the first 24 h, the patient also received three doses of lactulose, N-acetylcysteine, and intravenous fluids. The patient was subsequently diagnosed with a single, large intrahepatic portosystemic shunt via computed tomography and underwent an endovascular coil embolization procedure. Given the rapid and dramatic improvement in severe neurologic signs after ILE therapy alone, it is strongly suspected that this treatment resulted in improvement of hepatic encephalopathy.

Objectives The objective of the study was to evaluate whether oral cobalamin supplementation can restore normocobal-aminaemia in cats with hypocobalaminaemia and clinical signs of gastrointestinal disease. Methods This was a retrospective study based on a computerised database search for client-owned cats treated at Evidensia Specialist Animal Hospital, Helsingborg, Sweden, during the period December 2013 to August 2016. Inclusion criteria were cats with clinical signs of chronic enteropathy, an initial serum cobalamin concentration ⩽250 pmol/l (reference interval 214–738 pmol/l) and oral treatment with cobalamin tablets. Results Twenty-five cats met the inclusion criteria. The cats were treated with 0.25 mg cyanocobalamin tablets once daily. Serum cobalamin concentration was rechecked 27–94 days after continuous oral cobalamin supplementation. All cats had serum cobalamin concentrations above the reference interval after oral cobalamin supplementation. Median (range) serum cobalamin concentration was 128 pmol/l (111–250 pmol/l) prior to treatment and 2701 pmol/l (738–16,359 pmol/l) after supplementation. This difference was statistically significant ( P <0.0001). Conclusions and relevance Our results suggest that oral cobalamin supplementation is effective in increasing serum cobalamin to supranormal concentrations in cats with hypocobalaminaemia. Thus, oral cobalamin supplementation is a promising alternative to parenteral administration. Prospective comparative studies in cats being treated with parenteral vs oral cobalamin supplementation in a larger number of patients are warranted before oral supplementation can be recommended for routine use.

The Difference

Background: Acute myocarditis and acute myocardial infarction have frequently similar clinical presentations and poses an important clinical challenge in the differential diagnosis. In both cases, the electrocardiographic ST-T changes and an increase in troponins can be noted. Differential diagnosis may be very challenging and requires invasive assessment of coronary arteries and other investigations especially cardiac magnetic resonance. Case Presentation: In this report, we report a rare case of acute myocarditis misdiagnosed to an acute myocardial infarction in a patient presented to the emergency department for an acute onset of chest pain with ST-segment elevation on electrocardiogram for which he received urgent fibrinolysis. The confirmation of acute myocarditis was confirmed posteriori after a normal coronary angiogram using cardiac Magnetic Resonance Imaging cMRI. Conclusions: Clinical signs as long with Electrocardiogram may mimick a ST elevation myocardial infarction in the presence of an authentic acute myocarditis,Hence, cardiac magnetic resonance could present an intersting tools to make the difference even in acute phase.
