RESUMO

Hepatic portal venous gas is diagnosed via computed tomography due to unusual imaging features. HPVG when linked with pneumatosis intestinalis has a high mortality rate and required urgent intervention. We present a case of a 26-year-old young adult with superior mesenteric artery thrombosis who presented with severe abdominal pain. On imaging, HPVG and pneumatosis intestinalis were seen owing to the urgent intervention of the patient. The reliable interpretation of the imaging findings along with quick intervention led to a favorable outcome in our case. Herein, we present a thorough review of the imaging findings of HPVG to make a reliable diagnosis when presented with such a case.

RESUMO

Neonatal gastric perforation (NGP) is a rare life-threatening condition among preterm infants. NGP can occur secondary to necrotizing enterocolitis, distal obstruction, or as a result of gastric tube insertion. Sleeve gastrectomy can be a possible therapeutic option for multiple neonatal gastric perforations.

RESUMO

Introduction: Myositis, Raynaud's phenomenon, fever, interstitial lung disease, mechanic's hands, and arthropathy are symptoms of Antisynthetase Syndrome (ASS), which is defined by the development of antibodies against t-ribonucleic acid (RNA) synthetase, particularly anti-Jo-1. Case presentation: The case is about 29 years female with 1 month history of non-productive cough and dyspnea on exertion which was later diagnosed as ASS. Discussion: The diagnosis of an inflammatory myopathy is based on clinical findings such as subacute development of symmetrical muscle weakness and signs such as laboratory investigations revealing skeletal muscle inflammation. Creatinine phosphokinase (CPK) is mainly used to demonstrate skeletal muscle involvement. Conclusion: Interstitial lung disease is a frequent occurrence and is associated with a bad prognosis during the course of antisynthetase syndrome.

RESUMO

Introduction: Coronary embolism (CE) is a rare cause of acute ST-elevation myocardial infarction (STEMI). Atrial fibrillation (AF), left ventricular thrombus, septic emboli from infective endocarditis, myxoma, and paradoxical embolism can induce emboli in coronary arteries. Case presentation: Here we present a case of anterior wall STEMI secondary to paroxysmal AF in a 60-years-old female with a previous history of right-sided ischemic stroke. Discussion: The major criteria for diagnosis of coronary embolism include (1) non-atherosclerotic wall of coronary vessels under angiography; (2) concomitant involvement of multiple sites; (3) histological proof of venous thrombus; (4) imaging by echocardiography/CT/MRI showing intra-cardiac thrombus. The minor criteria include (1) <25% stenosis of other vessels supplying to infarct-free myocardium; (2) atrial fibrillation history; (3) risk factors like (prosthetic valve, bacterial endocarditis, patent foramen ovale, atrial septal defect, dilated cardiomyopathy). Conclusion: Our case highlights the importance of cardiac embolus as a diagnosis in a patient with a history of stroke secondary to atrial fibrillation as a cause of acute STEMI and its management.

RESUMO

Electrochemical biosensor holds great promise in the biomedical area due to its enhanced specificity, sensitivity, label-free nature and cost effectiveness for rapid point-of-care detection of diseases at bedside. In this review, we are focusing on the working principle of electrochemical biosensor and how it can be employed in detecting biomarkers of fatal diseases like cancer, AIDS, hepatitis and cardiovascular diseases. Recent advances in the development of implantable biosensors and exploration of nanomaterials in fabrication of electrodes with increasing the sensitivity of biosensor for quick and easy detection of biomolecules have been elucidated in detail. Electrochemical-based detection of heavy metal ions which cause harmful effect on human health has been discussed. Key challenges associated with the electrochemical sensor and its future perspectives are also addressed.

RESUMO

A series of 27 aryl/heteroaryl/aralkyl/aroyl piperazines were synthesized, and most of these compounds reduced prostate weight of mature rats by 15-47%. Three compounds, 10, 12, and 18, had better activity profile (reduced prostate weight by 47%, 43%, and 39%, respectively) than the standard drug flutamide (24% reduction). QSAR suggested structures with more cyclic and branched moieties, increased topological separation of O and N therein, and reduced solvation connectivity index for better activity. Pharmacokinetic study with compound 10 at an oral dose of 10.0 mg/kg indicated good absorption, negligible extrahepatic elimination, and rapid distribution to the target organ (prostate) but restricted entry through the blood-brain barrier. A 10-fold decrease in PSA and 15-fold increase in ER-ß gene expressions of human prostate cancer cells (LNCaP) by compound 10 in vitro indicated AR and ER-ß mediated actions. The findings may stimulate further explorations of identified lead for the management of benign prostatic hyperplasia.

RESUMO

5-Styryl-4,5-cis-1,3-oxazole-2-one-4-carboxylic acid (CDRI-85/92) is a new proton pump inhibitor presently in advanced stage of preclinical trials as antiulcer pharmacophore. Since proton pump inhibitors are prodrugs requiring activation in acid environment, an ester prodrug of CDRI-85/92 was also synthesized. In view of the importance, a pharmacokinetic study of CDRI-85/92 and its ester prodrug was conducted after oral doses in rats. Following a 20 mg/kg oral dose of CDRI-85/92, the compound was detectable in the serum samples up to 24 h with a maximum serum concentration (C(max)) of 1838.40 +/- 101.16 ng/ml at 1.5 h and an elimination half-life of 4.96 h, whereas, multiple C(max) values of CDRI-85/92 were observed with oral doses (equivalent to 20 mg/kg of CDRI-85/92) of the ester prodrug of the compound. All the three C(max) values of the compound were lower than that after oral dose of CDRI-85/92. The compound was eliminated slowly from serum with an elimination half-life of 5.14 h. Moreover, the systemic availability of CDRI-85/92 also decreased from 6111 to 3463 ng x h/ml after the ester prodrug administration. The decrease in systemic availability of CDRI-85/92 could be due to its higher clearance after its ester prodrug administration.
