Neurocysticercosis is the most common parasitic infection of the central nervous system caused by larvae of Taenia solium. Spinal cysticercosis is an uncommon site of cysticercal infection, and ...isolated intramedullary involvement is even rarer. We present a case of 10-year-old girl who presented with gradual onset paraparesis with sensory loss and bowel and bladder incontinence. Magnetic resonance imaging (MRI) of spine revealed a cystic lesion with mural nodule (scolex) which was diagnostic for cysticercosis. Patient was treated with antihelminthic, which led to marked clinico-radiological improvement.
Balo's concentric sclerosis (BCS) is a rare inflammatory demyelinating disease of central nervous system, pathologically characterized by alternate bands of demyelination and preserved myelin tissue. ...Before the era of magnetic resonance imaging (MRI), most cases of BCS were diagnosed on postmortem examination. MRI allows for noninvasive diagnosis by demonstrating characteristic changes which closely parallels the histopathological features of BCS. We report a case of 26-year-old female with BCS involving bilateral thalami, with typical MRI appearance.
Mediastinal teratomas are usually asymptomatic tumors, located most commonly in the anterior mediastinum. Very rarely, such tumors may rupture into the tracheobronchial tree, lung, pleura or ...pericardium. Computed Tomography (CT) is helpful in the diagnosis and differentiation of ruptured and unruptured tumors. We report a case of ruptured anterior mediastinal teratoma in a 20-year-old female presenting with recurrent hemoptysis and cough; thus, mimicking a lung malignancy or tuberculosis. CT demonstrated a heterogeneous fat containing lesion in the anterior mediastinum with extension into the lingular lobe. Subsequent fine needle aspiration cytology (FNAC) yielded plenty of anucleate squames and debris, and a clear cut diagnosis could not be made. Total excision of the tumor was performed and histopathology of the surgically excised mass confirmed the CT diagnosis.

Understanding the molecular and phenotypic profile of colorectal cancer (CRC) in West Africa is vital to addressing the regions rising burden of disease. Tissue from unselected Nigerian patients was ...analyzed with a multigene, next-generation sequencing assay. The rate of microsatellite instability is significantly higher among Nigerian CRC patients (28.1%) than patients from The Cancer Genome Atlas (TCGA, 14.2%) and Memorial Sloan Kettering Cancer Center (MSKCC, 8.5%, P < 0.001). In microsatellite-stable cases, tumors from Nigerian patients are less likely to have APC mutations (39.1% vs. 76.0% MSKCC P < 0.001) and WNT pathway alterations (47.8% vs. 81.9% MSKCC, P < 0.001); whereas RAS pathway alteration is more prevalent (76.1% vs. 59.6%, P = 0.03). Nigerian CRC patients are also younger and more likely to present with rectal disease (50.8% vs. 33.7% MSKCC, P < 0.001). The findings suggest a unique biology of CRC in Nigeria, which emphasizes the need for regional data to guide diagnostic and treatment approaches for patients in West Africa.
Heart failure with preserved ejection fraction (HFpEF) is a common heterogeneous syndrome that remains imprecisely defined and consequently has limited treatment options and poor outcomes.
The UK ...Heart Failure with Preserved Ejection Fraction Registry (UK HFpEF) is a prospective data-enabled cohort and platform study. The study will develop a large, highly characterised cohort of patients with HFpEF. A biobank will be established. Deep clinical phenotyping, imaging, multiomics and centrally held national electronic health record data will be integrated at scale, in order to reclassify HFpEF into distinct subgroups, improve understanding of disease mechanisms and identify new biological pathways and molecular targets. Together, these will form the basis for developing diagnostics and targeted therapeutics specific to subgroups. It will be a platform for more effective and efficient trials, focusing on subgroups in whom targeted interventions are expected to be effective, with consent in place to facilitate rapid recruitment, and linkage for follow-up. Patients with a diagnosis of HFpEF made by a heart failure specialist, who have had natriuretic peptide levels measured and a left ventricular ejection fraction >40% are eligible. Patients with an ejection fraction between 40% and 49% will be limited to no more than 25% of the cohort.
UK HFpEF will develop a rich, multimodal data resource to enable the identification of disease endotypes and develop more effective diagnostic strategies, precise risk stratification and targeted therapeutics.
