Streptococcus suis, a gram-positive facultative anaerobe commonly found in pigs, is an emerging zoonotic pathogen. Herein, we describe a case of a 45-year-old male Japanese meat wholesaler with S. suis meningitis and pyogenic ventriculitis. S. suis was isolated from his blood and cerebrospinal fluid culture, and sequence type (ST) and serotype were confirmed to be ST1 and serotype 2, respectively, by multilocus sequence typing and the Quellung reaction. Magnetic resonance imaging (MRI) revealed right labyrinthitis and pyogenic ventriculitis...

Post-infarction ventricular septal defect (VSD) is a rare but potentially lethal complication of acute myocardial infarction. Medical management is usually futile, so definitive surgery remains the treatment of choice but the risk surgery is very high and the optimal timing for surgery is still under debate. A 55-year-old man with no previous medical history attended the emergency-room for 12 h evolution of oppressive chest pain and strong anginal pain 7 days ago. On physical examination, blood pressure was 96/70 mmHg, pansystolic murmur over left sternal border without pulmonary crackles...

Invasive pneumococcus is a serious illness with potentially devastating outcomes. A 64-year-old female with a medical history of psoriatic arthritis and diabetes was transferred from an outside hospital for ventilator dependent respiratory failure and altered mental status. She initially presented with worsening back pain and was found to have leukocytosis with bandemia and acute renal failure but she was in septic shock upon arrival to our tertiary care center. Her blood cultures grew Streptococcus pneumoniae and MRI of the brain revealed pus within the posterior lateral ventricles and multiple infarcts...

A 04-year-old boy was referred to our institution with severe, progressive heart failure of 4-months duration associated with a persistent wide QRS tachycardia with left bundle branch block and severe left ventricular dysfunction. Because of incessant wide QRS tachycardia refractory to antiarrhythmic drugs, he was referred for electrophysiological study. The ECG was suggestive of VT arising from the right ventricle near the His area. Electrophysiological study revealed that origin of tachycardia was septum of the right ventricle, near His bundle, however the procedure was not successful and an inadvertent complete atrioventricular conduction block occurred...

BACKGROUND: The human heart contains varying amounts of fat deposits. Cardiac physiological fat occurs predominantly in the right ventricle (RV). The discovery and characterization of adipose tissue along the left ventricle (LV) has been rarely reported. This study aimed to determine the occurrence of fatty deposits in epicardial, pericoronay and myocardial compartments in the LV, and to trace the epidemiological profile and clinical associations with this finding. METHODS: Epidemiological and morphological data and heart samples were collected from corpses submitted to necropsy...

A 40-day-old male, blue heeler puppy with hindlimb ataxia, nystagmus, apathy, motor incoordination and hyperaesthesia of the forelimbs died 3 days after the onset of clinical signs. Significant gross findings included cerebellar herniation, cerebral oedema and dilation of the third and right lateral cerebral ventricles due to the accumulation of a purulent exudate. Histopathological examination revealed pyogenic ventriculitis and purulent meningoencephalitis. Pure colonies of a coagulase-positive Staphylococcus were isolated from the purulent cerebral exudate...

This overview gives an update on the molecular mechanisms, clinical manifestations, diagnosis and therapy of arrhythmogenic cardiomyopathy (ACM). ACM is mostly hereditary and associated with mutations in genes encoding proteins of the intercalated disc. Three subtypes have been proposed: the classical right-dominant subtype generally referred to as ARVC/D, biventricular forms with early biventricular involvement and left-dominant subtypes with predominant LV involvement. Typical symptoms include palpitations, arrhythmic (pre)syncope and sudden cardiac arrest due to ventricular arrhythmias, which typically occur in athletes...

BACKGROUND: Isolated tricuspid valve replacement is rare when performed as a re-operation after a left side operation. It is important to know the factors that determine mortality and morbidity. Tricuspid Annular Plane Systolic Excursion (TAPSE) is a scoring system that is used with non-invasive Doppler echocardiography to determine right ventricular (RV) function. This study analyzed TAPSE scores and adverse outcomes of isolated tricuspid valve surgery in patients with previous cardiac surgery...

Left ventricular noncompaction cardiomyopathy (LVNC) is a clinically heterogeneous disorder characterized by a trabecular meshwork and deep intertrabecular myocardial recesses that communicate with the left ventricular cavity. Several genetic causes of LVNC have been reported, with variable modes of inheritance, including autosomal dominant and X-linked inheritance, but relatively few responsible genes have been identified. A NGS workflow, based on a panel of 95 genes developed for sequencing most prevalent sudden cardiac death-causing genes, was used to make a rapid and costless molecular diagnosis in two siblings with a severe noncompaction cardiomyopathy starting prenatally and leading to rapid cardiac failure...

BACKGROUND: Central nervous system (CNS) melioidosis is notorious because of the difficulty in bacteria eradication and the destruction of brain structures. Early manifestation of CNS melioidosis mimics malignancy or stroke. We present a case of CNS melioidosis that initially manifested as malignancy. CASE DESCRIPTION: A 30-year-old man presented with sudden onset of left limb weakness and seizure. Computed tomography of the brain showed a low-density lesion over the right parietal lobe, and magnetic resonance imaging showed a well-enhanced lobulated lesion...

We report a case of a 18-year-old boy who presented with dyspnea and right upper quadrant abdominal dull pain. According to urgent echocardiography, a dense sessile mass occupied the right ventricule. Tumor resection was performed, followed by further adjuvant therapy. The specimen was histopathologically investigated and eventually diagnosed as metastatic adult hepatoblastoma. We discuss its clinical features and treatment in the light of the current knowledge. It is important for us to be aware that adjuvant chemotherapy might be an effective alternative in the treatment of hepatoblastoma combined with ventricle invasion...

Hypoplastic left heart syndrome (HLHS) is one of the most challenging congenital heart defects which require surgical interventions during neonatal period. Since the 1st successful surgical repair was reported by Norwood et al. more than 30 years ago, some modifications in surgical maneuver [e. g. introduction of right ventricule (RV)-pulmonary artery (PA) shunt] and improvement of perioperative management have brought better outcome for this patient cohort. Recent years our institute have changed the treatment strategy from primary Norwood operation during neonatal period to bilateral PA banding and subsequent Norwood operation during early infantile (we call it as "rapid 2 stage Norwood operation")...

Neither guidelines nor best practices for the treatment of external ventricular drain (EVD) and ventriculoperitoneal shunt infections exist. An antimicrobial regimen with a broad spectrum of activity and adequate cerebrospinal fluid (CSF) penetration is vital in the management of both EVD and ventriculoperitoneal infections. In this case report, we describe the pharmacokinetics of continuous-infusion meropenem for a 2-year-old girl with Serratia marcescens ventriculitis. A right frontal EVD was placed for the management of a posterior fossa mass with hydrocephalus and intraventricular hemorrhage...

Pyogenic ventriculitis is an uncommon and potentially fatal central nervous system infection. Delayed treatment due to non specific clinical symptoms may lead to an unfavorable outcome. Brain magnetic resonance imaging (MRI) plays an important role in the diagnosis of pyogenic ventriculitis. We describe two patients with pyogenic ventriculitis presenting with a pathognomonic MRI finding. The first patient, a 77-year-old female, developed high fever and consciousness disturbance. MR images revealed hyperintense lesions with a fluid-fluid level in the bilateral lateral ventricles on diffusion-weighted images (DWIs) and hypointense lesions on T2-weighted images (T2WIs)...

BACKGROUND: Escherichia coli (E. coli) is the most common causative bacteria of neonatal meningitis, but hematogenous intracranial E. coli infection is rare in adults. Moreover, intracranial abscess formation owing to E. coli, including brain abscesses and subdural empyema formation, is extremely rare. We herein present a case involving a patient with a brain abscess owing to E. coli following a simple renal cyst infection. A review of the literature is also presented. CASE PRESENTATION: A 77-year-old Japanese woman with a history of polymyalgia rheumatica was admitted to our hospital because of persistent fever, right flank pain, and pyuria...
