The left ventricle is a less frequent location of cardiac myxomas overall. Meanwhile, cardiac myxomas related to Carney complex (CNC), which is a multiple neoplasia syndrome involving cardiac, endocrine, neural, and cutaneous tumours, more frequently occur in the left ventricle compared with sporadic cardiac myxomas. Herein, we report a case of a 20-year-old woman with CNC who underwent complete surgical excision of a large and mobile left ventricular myxoma. In our case, echocardiography performed 4 years earlier was normal...

Sotos syndrome is a rare congenital syndrome caused by deletions or mutations in the NSD1 gene (chromosome 5q35) which results in overgrowth. A wide range of manifestations may result in unexpected and/or early death, including congenital cardiac malformations and tumours, epilepsy, intra-tumoural haemorrhage or embolism and bleeding diatheses. A case of lethal pulmonary fat embolism complicating revision of a left total hip replacement following spontaneous fracture is reported in a 39-year-old man with Sotos syndrome...

A 23-year-old Asian student presented to our service with a 1-month history of fever, weight loss of 10 kg, night sweats, fatigue and general malaise. He was previously well with no significant medical or family history. He had a low-grade pyrexia and cardiac auscultation revealed a diastolic murmur consistent with 'tumour plop'. He had no sequelae of endocarditis. He had low-grade pyrexia of 37.7°C, and ECG showed sinus tachycardia at 130 bpm. He had raised inflammatory markers and was started on broad spectrum antibiotics...

It is generally accepted that insulin exerts an antiapoptotic effect against ischemia/reperfusion through the activation of PI3K/Akt/mTOR pathway. MicroRNAs involve in multiple cardiac pathophysiological processes, including ischemia/reperfusion-induced cardiac injury. However, the regulation of microRNAs in the cardioprotective effect of insulin is rarely discussed. In this study, using a cell model of ischemia through culturing H9C2 cardiac myocytes in serum-free medium with hypoxia, we demonstrated that pretreatment with insulin significantly inhibited cell apoptosis and downregulated microRNA-320 (miR-320) expression...

Metformin has been used as a glucose lowering drug for several centuries and is now a first-line drug for type 2 diabetes mellitus (T2DM). Since the discovery that it activates AMP-activated protein kinase (AMPK) and reduces risk of cancer, metformin has drawn great attentions. Another drug, berberine, extracted from berberis vulgaris L. (root), was an ancient herbal medicine in treating diarrhea. Ongoing experimental and clinical studies have illuminated great potential of berberine in regulation of glucose and lipid homeostasis, cancer growth and inflammation...

BACKGROUND: Transforming growth factor β1 (TGF-β1) and tumour necrosis factor (TNF) have been implicated in Chagas disease pathophysiology and may correlate with left ventricular (LV) function. OBJECTIVES: We determined whether TGF-β1 and TNF serum levels correlate with LV systolic and diastolic functions and brain natriuretic peptide (BNP) serum levels in chronic Chagas disease. METHODS: This cross-sectional study included 152 patients with Chagas disease (43% men; 57 ± 12 years old), classified as 53 patients with indeterminate form and 99 patients with cardiac form (stage A: 24, stage B: 25, stage C: 44, stage D: 6)...

OBJECTIVES: Malignant intracardiac tumours are rare, and consensus concerning the optimal therapeutic approach is lacking. We performed a retrospective medical analysis, identifying 9 patients having been operated for cardiac sarcomas. All of them had a complete postoperative long-term follow-up. To enhance understanding of the best therapeutic approach for future patients, it is crucial to reveal special medical problems and to analyse the potential impact they may have on disease course and survival rate in this specific patient group...

OBJECTIVES: This study aimed to investigate the cardioprotective effects of melatonin on heat stroke (HS) induced acute myocardial infarction in rats and to explore the underlying mechanisms. METHODS: Myocardial injury was induced by subjecting the anaesthetized rats to a high ambient temperature of 43°C for 70 min. Such a high ambient temperature caused hyperthermia, hypotension and myocardial injury in rats. Rats were treated with melatonin (3 mg/kg) intravenously one hour before and followed by an additional dose immediately after heat stress...

OBJECTIVES: Patients with rheumatoid arthritis and spondyloarthritisshow higher mortality rates, mainly caused by cardiac comorbidities. The TghuTNF (Tg197) arthritis model develops tumour necrosis factor (TNF)-driven and mesenchymalsynovial fibroblast (SF)-dependent polyarthritis. Here, we investigate whether this model develops, similarly to human patients, comorbid heart pathology and explore cellular and molecular mechanisms linking arthritis to cardiac comorbidities. METHODS: Histopathological analysis and echocardiographic evaluation of cardiac function were performed in the Tg197 model...

We report the case of a 77-year-old woman presenting with out-of-hospital cardiac arrest, which was then interpreted as an acute, life-threatening critical airway compression by a huge mediastinal tumour without appropriate diagnosis. Emergency extracorporeal membrane oxygenation was cannulated for sufficient respiratory support after spontaneous circulation was regained. After the multidisciplinary team, involving thoracic surgeons, discussed the resectability of the mediastinal tumour, the patient underwent successful resection of the mediastinal tumour through a median sternotomy...

IKKβ has previously been implicated in breast cancer bone metastasis and bone remodelling. However, the contribution of IKKβ expressed by bone cells of the tumour microenvironment to breast cancer-induced osteolysis has yet to be investigated. Here, we studied the effects of the verified selective IKKβ inhibitors IKKβIII or IKKβV on osteoclast formation and osteoblast differentiation in vitro and in vivo, human and mouse breast cancer cells' support for osteoclast formation and signalling in vitro and osteolysis ex vivo and in immunocompetent mice after supracalvarial injection of human MDA-MB-231 conditioned medium or intra-cardiac injection of syngeneic 4T1 breast cancer cells...

A 17-year-old male presented with a large sebaceous naevus (SN) comprising part of his left face and scalp and a speckled lentiginous naevus (SLN) on his right trunk, hip, neck and scalp with a checkerboard pattern. His right oral hemimucosa showed extensive papillomatous lesions which were contiguous to the upper lip SN lesions. As for extracutaneous manifestations he suffered from cardiac, musculoskeletal and ocular alterations. On the other hand, he developed two primary rhabdomyosarcomas. DNA samples of the SN, SLN, the oral papillomatous hyperplasia and both rhabdomyosarcomas were analyzed by Sanger sequencing...

BACKGROUND: Multiple myeloma is characterised by monoclonal paraprotein production and osteolytic lesions, commonly leading to skeletal-related events (spinal cord compression, pathological fracture, or surgery or radiotherapy to affected bone). Denosumab, a monoclonal antibody targeting RANKL, reduces skeletal-related events associated with bone lesions or metastases in patients with advanced solid tumours. This study aimed to assess the efficacy and safety of denosumab compared with zoledronic acid for the prevention of skeletal-related events in patients with newly diagnosed multiple myeloma...

BACKGROUND: Pheochromocytomas (PH) and paragangliomas (PGL) are rare tumours in children accounting for about 1% of the paediatric hypertension. While minimally invasive surgical techniques are well established in adult patients with PH, the experience in children is extremely limited. To the best of our knowledge, we herewith present the largest series of young patients operated on chromaffin tumours by minimally invasive access. MATERIALS: In the setting of a prospective study (1/2001-12/2016), 42 consecutive children and adolescents (33 m, 9 f) were operated on...

OBJECTIVES: Volatile anaesthetics can provide significant protection against reperfusion injury in various experimental settings. The aim of this study was to assess the potential of sevoflurane treatment, the most commonly used volatile anaesthetic in modern anaesthesia, in rat lungs donated after circulatory death and reconditioned in an ex vivo lung perfusion (EVLP) system. METHODS: Fifteen rats were sacrificed and divided into 3 groups. In the control and sevoflurane groups, the heart-lung blocks were exposed to 1 h of warm ischaemia and 2 h of cold ischaemia and were mounted on an EVLP circuit for 3 h, in the absence or in the presence of 2% sevoflurane...
