Intra-cardiac extension of tumour thrombus of follicular carcinoma of thyroid is uncommon. We report a case of advanced thyroid carcinoma where tumour thrombus was well profiled with CT scan and transesophageal echo images and extension was noted from SVC into right atrium, with clinical features of superior vena cava syndrome. The clinical significance of the "ring sign" is discussed.

BACKGROUND: In a phase 2 study in patients with metastatic renal cell carcinoma, overall survival was associated with T-cell responses against IMA901, a vaccine consisting of ten tumour-associated peptides. In this phase 3 trial, we aimed to determine the clinical effect of adding IMA901 to sunitinib, the standard first-line treatment in metastatic renal cell carcinoma with postulated favourable immunomodulatory effects. METHODS: The IMPRINT study is an open-label, randomised, controlled, phase 3 trial done at 124 clinical sites in 11 countries...

Phaeochromocytomas and paragangliomas (PPGLs) are catecholamine secreting neuroendocrine tumours that predispose to haemodynamic instability. Currently, surgery is the only available curative treatment, but carries potential risks including hypertensive and hypotensive crises, cardiac arrhythmias, myocardial infarction and stroke, due to tumoral release of catecholamines during anaesthetic induction and tumour manipulation. The mortality associated with surgical resection of PPGL has significantly improved from 20-45% in the early 20(th) century(1) to 0-2...

The present work aims to investigate targeting potential of doxorubicin (Dox) functionalized gold nanoparticles (D-GNPs) for treatment of chemically induced fibrosarcoma in mice. Carrier GNPs were synthesised by green chemistry method and loaded with doxorubicin by incubation method. D-GNPs were studied for its biocompatibility using normal mouse fibroblasts (L929) and found to be cell compatible and non-toxic. D-GNPs (at a dose of 2.5, 2 and 1.5mg/kg equivalent to Dox) demonstrated passive targeting measured as function of antitumor efficacy against chemical induced fibrosarcoma which showed higher latency to the tumour growth as compared to free Dox (2...

The aim of this study was to evaluate the serum biochemistry profile, inflammatory cytokines, adipokines and cardiovascular findings in obese dogs. Twenty obese and 20 normal weight healthy pet dogs were recruited into the study, where they underwent blood testing and assessment of cardiovascular function (blood pressure analysis, electrocardiography and echocardiography). Higher concentrations of total cholesterol, triglycerides, lactate dehydrogenase, total serum proteins, α-globulins, total bilirubin, insulin, insulin:glucose ratio, alkaline phosphate and alanine aminotransferase were observed in obese dogs than dogs of normal weight...

Doxorubicin is a widely used and effective chemotherapy drug. However, cardiac and skeletal muscle toxicity of doxorubicin limits its use. Inhibiting myostatin/activin signalling can prevent muscle atrophy, but its effects in chemotherapy-induced muscle wasting are unknown. In the present study we investigated the effects of doxorubicin administration alone or combined with activin receptor ligand pathway blockade by soluble activin receptor IIB (sACVR2B-Fc). Doxorubicin administration decreased body mass, muscle size and bone mineral density/content in mice...

Stroke of undetermined aetiology or 'cryptogenic' stroke accounts for 30-40% of ischaemic strokes despite extensive diagnostic evaluation. The role and yield of cardiac imaging is controversial. Cardiac MRI (CMR) has been used for cardiac disorders, but its use in cryptogenic stroke is not well established. We reviewed the literature (randomised trials, exploratory comparative studies and case series) on the use of CMR in the diagnostic evaluation of patients with ischaemic stroke. The literature on the use of CMR in the diagnostic evaluation of ischaemic stroke is sparse...

Introduction Radiotherapy is not commonly used for the treatment of gastric cancer in Japan, where surgery is the standard local treatment. We report the results of chemoradiotherapy in patients with advanced or recurrent gastric cancer which was deemed difficult to treat surgically. Methods Twenty-one patients with gastric cancer (including sixteen with advanced/recurrent gastric cancer and five with poor general condition) underwent chemo-radiotherapy, for whom the therapeutic efficacy, toxicity and survival period were analysed...

Leiomyoma is the most common oesophageal tumour and is symptomatic in about half of the patients. Dysphagia is the most common symptom. A 41-year-old woman presented with recent onset of severe orthostatic hypertension. During the cardiological work-up, a mediastinal mass was found at transthoracic echocardiogram. Further investigation (upper gastrointestinal endoscopy, endoscopic ultrasonography, CT scan and cardiac MRI) confirmed the diagnosis of a large oesophageal submucosal mass compressing the supradiaphragmatic inferior vena cava...

Clear cell meningiomas are an uncommon subtype of meningioma rarely seen in infancy. We report a case of clear cell meningioma in an 8-month-old male infant. He presented at the Lagos University Teaching Hospital, Lagos, Nigeria, in 2015 with persistent vomiting, poor feeding and failure to thrive over a four month period. Generalised hypertonia and hyperreflexia were noted on examination. Computed tomography of the brain revealed a huge largely isodense suprasellar mass with a hypodense core. The tumour, which measured 6 × 5 × 4 cm, enhanced non-uniformly with contrast injection and extended to occlude the third ventricle...

INTRODUCTION: Voltage-gated sodium channel (VGSC)-inhibiting drugs are commonly used to treat epilepsy and cardiac arrhythmia. VGSCs are also widely expressed in various cancers, including those of the breast, bowel and prostate. A number of VGSC-inhibiting drugs have been shown to inhibit cancer cell proliferation, invasion, tumour growth and metastasis in preclinical models, suggesting that VGSCs may be novel molecular targets for cancer treatment. Surprisingly, we previously found that prior exposure to VGSC-inhibiting drugs may be associated with reduced overall survival in patients with cancer, but we were unable to control for the cause of death or indication for prescription...

Pericytes are periendothelial mesenchymal cells residing within the microvasculature. Skeletal muscle and cardiac pericytes are now recognized to fulfill an increasing number of functions in normal tissue homeostasis, including contributing to microvascular function by maintaining vessel stability and regulating capillary flow. In the setting of muscle injury, pericytes contribute to a regenerative microenvironment through release of trophic factors and by modulating local immune responses. In skeletal muscle, pericytes also directly enhance tissue healing by differentiating into myofibers...

To date, there have been less than a 100 confirmed case reports of primary cardiac malignant fibrous histiocytomas, a rare form of sarcoma. In this report, we discuss the case of a 15-year-old girl who initially presented with a histiocytic cerebral sarcoma that was treated with aggressive resection and chemotherapy. Three years later, the same patient developed increasing shortness of breath and was found to have a high-grade pleomorphic undifferentiated cardiac sarcoma that likely represents the primary tumour from which the cerebral lesion metastasised...

Myocardial infarction continues to be a major public health problem. Reduction in mortality rate and prevention of myocardial infarction are of utmost importance. Inflammation and thrombosis play an important role in the pathogenesis of myocardial infarction. The anti-inflammatory and anti-thrombotic effects of zingerone were evaluated in isoproterenol induced myocardial infarcted rats. Rats were pretreated with zingerone (6mg/kg body weight) daily for 14 days and were then induced myocardial infarction with isoproterenol (100mg/kg body weight) on 15th and 16th day...

Carcinoid tumours arising from the thymus are exceedingly rare, and cardiac metastases have not previously been described in the setting of a primary thymic carcinoid tumour. We present a patient with recurrence of a carcinoid tumour initially resected from the thymus 15 years earlier, with multiple cardiac metastases. These metastatic tumours were visualized using multiple imaging modalities, including computed tomography, transthoracic echocardiogram, magnetic resonance imaging, and octreotide scan. A subsequent biopsy confirmed recurrence of his carcinoid tumour...

Cardiac rhabdomyoma is the most common tumour of the heart in infancy and childhood, representing approximately 60% of all primary cardiac tumours in these age groups. Though they have a tendency to regress with advancing age and are histologically benign, rhabdomyomas may cause mechanical obstruction to blood flow, arrhythmia, congestive cardiac failure and death and may be associated with underlying genetic syndromes such as tuberous sclerosis. We present the case of a primigravida in her early 20s with no significant medical history who was referred to the Fetal Medicine Unit at 34 weeks' gestation following the detection of an irregular fetal heartbeat...

BACKGROUND: Some therapeutic agents in oncology can be causally associated with specific cardiovascular events including QT/QTc interval prolongation. We investigated the effect of multiple dosing of the oral poly (ADP-ribose)-polymerase (PARP) inhibitor, olaparib (tablet formulation) on QT/QTc interval. METHODS: Two phase I, open-label, three-part studies (NCT01921140 [study 4] and NCT01900028 [study 7]) were conducted in adults with refractory/resistant advanced solid tumours...
