Intracardiac platypnea-orthodeoxia syndrome (POS) is a pathological condition that leads to a reduction in oxygenation in the sitting position. The detection rate of patent foramen ovale that causes POS increases with Valsalva manoeuvre and cough. We report the case of a 92-year-old woman with POS, which could not be diagnosed in the sitting position. The Valsalva manoeuvre could not be performed because of dementia, and POS was diagnosed on the forward-bending position and abdominal compression. It was assumed that forward-bending increases the right atrial pressure by compressing the right ventricle along with elongation of the aorta, and abdominal compression increases the shunt volume by increasing the venous return. If POS is suspected in patients with dementia which cannot be diagnosed in the sitting position, forward-bending and abdominal compression, instead of the Valsalva manoeuvre, might be useful.A 15-year-old young woman was referred to the emergency room for admission by her general practitioner after receiving the results of urinary metanephrines and catecholamines requested to study the tachycardia, sweating and headaches that she had been presenting progressively last year. Imaging tests showed a large right supraumbilical para-aortic paraganglioma that was successfully removed with surgery after previous medical preparation with adrenergic blockers. Genetic testing showed a heterozygous mutation of the gene succinate dehydrogenase-B. The classic triad of symptoms in these disorders consists of headaches, sweating and tachycardia, usually accompanied by hypertension. We wanted to present this case, a challenging diagnosis of paraganglioma in primary care.We describe the case of an immunocompetent 75-year-old man with Capnocytophaga canimorsus bacteraemia and meningitis. C. canimorsus is commonly found in the oral flora of dogs with human infection typically occurring following a bite. Unusually, while our patient was a dog owner, there was no history of bite nor scratch mark. Admission blood cultures flagged positive for Gram-negative bacilli, but prolonged molecular analysis was required before C. canimorsus was isolated in blood and cerebrospinal fluid. Copanlisib There is a high mortality rate in invasive infection, and in our patient's case, antibiotic therapy was commenced prior to laboratory confirmation with our patient making a complete recovery. This case highlights the importance of including C. canimorsus in the differential diagnosis of unwell patients who keep dogs, even without a bite. This case occurred amid heightened awareness of COVID-19, which may represent predisposition for zoonoses during social isolation and increased human-pet contact.A 49-year-old woman presented to the hospital with shortness of breath 2 weeks after a left total hip replacement. She was found to have a submassive pulmonary embolism (PE), with her case complicated by the detection of a large mobile clot in transit extending through a patent foramen ovale between the right and left atria. The presence of this free-floating right heart thrombus (FFRHT) increases her risks of stroke and mortality, yet the optimal approach to her treatment was unclear. Ultimately, intravenous tissue plasminogen activator was administered with resolution of the clot. Treatment was complicated by haemodynamically insignificant bleeding at the site of recent surgery. Herein, we further discuss the implications and treatment options for patients with an FFRHT in the setting of an acute PE.A 74-year-old man with medical history significant for atrial fibrillation, hyperlipidaemia and coronary artery disease on atorvastatin presented to the emergency department with profound weakness. The patient reports he first noticed his weakness 4 weeks after starting colchicine, prescribed for recurrent pericarditis with pericardial effusion, a complication following recent coronary artery bypass grafting. The patient was also on prednisone therapy for presumed post-pericardiotomy syndrome. The weakness involved all four limbs but was more notable in the lower extremities, with preserved sensation and tenderness to palpation. Labs showed an elevated creatinine phosphokinase and serum creatinine consistent with rhabdomyolysis. Discontinuation of the offending medications, including colchicine and atorvastatin, as well as intravenous fluid resuscitation with physical rehabilitation, led to improvement in the patient's symptoms. He was eventually discharged to a rehabilitation facility to continue physical therapy.A 20-year-old woman was referred to the diabetes clinic with type 2 diabetes diagnosed at the age of 19. Her body mass index was 31.4 kg/m2, HbA1C was 76 mmol/mol, GAD antibodies were negative with a detectable C-peptide. She had a characteristic facial appearance with widespread eyes, posterior hairline suggesting a facial gestalt and abnormal dentition. She also had hypothyroidism, mild intellectual disability, primary amenorrhoea and patent ductus arteriosus. Karyotyping reported normal 46XX karyotype. Genetic testing revealed a pathogenic variant in the gene encoding the HIST1H1E protein which confirmed her diagnosis of HIST1H1E syndrome. Type 2 diabetes has not been reported in previous cases of HIST1H1E and so this is the first reported case of type 2 diabetes with HIST1H1E syndrome.This case report concerns a 63-year-old man affected by metastatic undifferentiated liposarcoma. After receiving pembrolizumab as a second-line treatment in a clinical trial, the patient experienced an immune-mediated myocarditis, myositis and myasteniform syndrome. The last two adverse events showed significant clinical relevance in terms of severity, duration and the required specific treatment.Initial treatment approach consisted in pulses of 1 g of methylprednisolone, followed by 2 mg/kg/day, with clinical improvement. After 12 days, the immune-mediated myasteniform syndrome worsened, with dysphagia, dysphonia, bilateral palpebral ptosis and respiratory difficulty. Due to the refractoriness to glucocorticoid treatment, it was decided to initiate intravenous immunoglobulin at 2 g/kg, followed by 2 mg/kg every 4 weeks once discharged and mycophenolate 500 mg/12 hours, in order to reduce the dose of glucocorticoids.After 2 months, the patient presented an optimal clinical evolution, without muscular weakness and referred to an improvement in dysphagia and speech.
