Subglottic hemangioma is a rare benign tumor in children. It causes an obstruction of the upper airway and can be life-threatening. Several therapeutic options have been used in the literature, including surgery. Currently, the treatment is essentially based on propranolol. We report the case of a 2-month-old female infant hospitalized for severe obstructive dyspnea secondary to a subglottic hemangioma. Diagnosis was confirmed by laryngoscopy and magnetic resonance imaging. The child underwent a tracheotomy and was treated with propranolol...

BACKGROUND: Cardiac resynchronization therapy (CRT) improves symptoms of heart failure (HF), morbidity and mortality in selected population. The aim of the study was to investigate the impact of cardiac magnetic resonance (CMR)-guided left ventricular (LV) lead placement on clinical outcomes and LV reverse remodelling in CRT recipients. METHODS: Patients with CRT indication were randomized for CMR-guided (CMR group) or electrophysiologically guided (EP group) LV lead placement between 2011 and 2014...

BACKGROUND Epidural venous plexus (EVP) engorgement occurs due to many conditions, so it can be easily misdiagnosed. This becomes problematic when the diagnosis requires prompt treatment for a good outcome, especially when it results in cauda equina syndrome (CES). We report a case of extensive iliocaval thrombosis leading to epidural venous plexus and ascending lumbar vein engorgement as an outcome of deep venous thrombosis (DVT) due to probable adverse effects of oral combined contraceptive pills (OCCP). CASE REPORT A 42-year-old woman presented to a rural medical facility with bilateral lower-limb swelling and skin darkening for 2 days...

Objective: To investigate the brain volume alterations in patients with hyposmia using voxel-based morphometry (VBM) and to correlate these alterations with the degree and duration of hyposmia. Methods: Forty patients with hyposmia from Department of Otorhinolaryngology Head and Neck Surgery, Beijing Anzhen Hospital since 2013 to 2016 and forty age and sex matched normal subjects were recruited in this study. Sniffin' Sticks olfactory test was performed to evaluate the olfactory function of all subjects. We acquired T1-weighted magnetic resonance images from all subject on a 3T scanner...

Acute right ventricle myocardial infarction (RVMI) is observed in 30-50% of patients presenting with inferior wall myocardial infarction and, occasionally, with anterior wall myocardial infarction. The clinical consequences vary from no hemodynamic compromise to severe hypotension and cardiogenic shock depending on the extent of RV ischemia. Areas covered: The pathophysiological mechanisms, diagnostic steps and novel therapeutic approaches of acute RVMI are described. Expert commentary: Diagnosis of acute RVMI is based on physical examination, cardiac biomarkers, electrocardiography and coronary angiography, whereas non-invasive imaging modalities (echocardiography, cardiac magnetic resonance imaging) play a complementary role...

RATIONALE: Reversible splenial lesion syndrome (RESLES) is a reversible condition with an excellent prognosis in most patients. The clinical features include altered states of consciousness, delirium, headache, and seizures, but no callosal disconnection syndromes have been described in RESLES. PATIENT CONCERNS: We presented a 57-year-old patient with alien hand syndrome, autotopagnosia, gait disorders, and left ideomotor apraxia after blood transfusion. The brain magnetic resonance imaging (MRI) showed a few regions with high signal intensity in the genu, body, and splenium of the right corpus callosum on diffusion weighted images...

The aim of the study was to explore anterior interhemispheric approach microsurgery for removing large sellar region tumors.A total of 118 patients with large sellar region tumors were treated with the anterior interhemispheric approach microsurgery. There were 58 craniopharyngioma, 37 pituitary adenoma, 5 hypothalamic glioma, 7 meningioma, and 11 other tumors cases. The maximal tumor diameter ranged from 3.0 to 8.2 cm, with a mean diameter of 4.3 cm. Diabetes insipidus and fluid and electrolyte imbalance were timely controlled after surgery...

RATIONALE: Paraneoplastic cerebellar degeneration (PCD) is an immune-mediated neurological deficit affecting the cerebellum. Anti-Yo antibody positive PCD is a rare occurrence most likely associated with gynecologic or breast malignancies. The identification of the underlying tumor is a diagnostic challenge in many of these patients. PATIENT CONCERNS: We present a 68-year-old woman with acute symptoms of PCD as a first sign of underlying occult malignancy. Further investigation revealed a positive anti-Yo antibody...

Rationale: Staphylococcus-associated glomerulonephritis (SAGN) is a rare immune complex-mediated glomerulonephritis associated with active Staphylococcus infection. We report a case illustrating the importance of clinical history and kidney biopsy findings in establishing the correct diagnosis. Presenting concerns of the patient: We report the case of a 64-year-old man with alcohol-associated cirrhosis, type 2 diabetes mellitus, and hypertension who presented to hospital with lower back and abdominal pain, rectal bleeding, a purpuric lower extremity rash, and oliguric acute kidney injury with microscopic hematuria and nephrotic-range proteinuria...

BACKGROUND: It has been reported that left ventricular (LV) myocardial strain and late gadolinium enhancement (LGE) on cardiovascular magnetic resonance (CMR) imaging have prognostic value in patients with heart failure (HF). However, previous studies included patients with various systolic functions. This study aimed to investigate the prognostic value of LV myocardial strain and LGE on CMR imaging in patients with idiopathic dilated cardiomyopathy (DCM) with reduced ejection fraction (EF < 40%)...

BACKGROUND: Currently, several geographies around the world remain underrepresented in medical device trials. The PANORAMA 2 study was designed to assess contemporary region-specific differences in clinical practice patterns of patients with cardiac implantable electronic devices (CIEDs). METHODS: In this prospective, multicenter, observational, multi-national study, baseline and implant data of 4,706 patients receiving Medtronic CIEDs (either de novo device implants, replacements, or upgrades) were analyzed, consisting of: 54% implantable pulse generators (IPGs), 20...

Introduction: Campylobacter is a common pathogen of the gastrointestinal tract, but invasive disease is rare. Campylobacter fetus can play a role in osteomyelitis, meningitis and joint infection and has a prediliction for the vascular endothelium, causing mycotic aneurysms, thrombophlebitis and endocarditis. Here we present a case of prosthetic valve endocarditis caused by C. fetus and a review of the literature. Case presentation: An 85-year-old woman with a tissue aortic valve replacement and atrial fibrillation was admitted to hospital with tonic-clonic seizures, right-sided hemiparesis, facial droop and hemianopia...

A 76-year-old woman was referred to our hospital due to massive gingival bleeding following teeth extraction. Laboratory findings suggested disseminated intravascular coagulopathy (DIC). Enhanced computed tomography and magnetic resonance imaging disclosed multiple hypervascular liver masses of 2-6 cm in diameter, the largest of which displaying an irregular enhancement pattern. We considered that her DIC was caused by the multiple liver masses and commenced repeated erythrocyte/fresh frozen plasma infusión and gabexate mesilate administration...

BACKGROUND: Myocardial involvement is common in acute idiopathic pericarditis and can, in some cases, lead to life-threatening complications. Acute idiopathic pericarditis is often preceded by various prodromal symptoms, but whether these symptoms can predict myocardial involvement is unclear. The aim of the study was to examine the value of different prodromal symptoms of acute idiopathic pericarditis for predicting myocardial involvement. METHODS AND RESULTS: Patients diagnosed with acute idiopathic pericarditis in 2007-2017 at our hospital were identified by database search...

Introduction In patients with cranial venous sinus thrombosis, the occurrence of subarachnoid haemorrhage in association with haemorrhagic venous infarcts is a well described phenomenon. However, the presence of subarachnoid haemorrhage in patients with cranial venous sinus thrombosis in the absence of a haemorrhagic venous infarct is exceedingly rare. Methods We retrospectively reviewed charts and scans of all patients who had cranial venous sinus thrombosis confirmed by magnetic resonance venography at our hospital between September 2004 and May 2015...
