Between January 2005 and August 2011 141 victims of krait bite poisoning were admitted to the general hospital at Mahad. Clinical signs and symptoms preceding the development of neuroparalysis were analyzed. Fifty-six percent of patients were male. A total of 140 victims reported between midnight and 05:00. Patients awoke in the night due to abdominal colic (85%) and chest pain (72%). Patients gave a history of vomiting (42%), sweating (17%) and excessive salivation (35%). On arrival at hospital, 78% cases had dysphasia with pooling of saliva, 89% had heaviness in both eyelids and ptosis; 12.5% of patients died on the way to hospital while 13.47% died during treatment. In total, 74.46% recovered, and of these 48% needed artificial ventilation. The sudden onset of abdominal colic and vomiting in a person sleeping on the floor without a mosquito net led to neuroparalysis due to krait bite poisoning.

A 19-year-old man presented with sudden onset of right eye ptosis, diplopia and giddiness. He had no previous medical illnesses with negative history of exertional dyspnoea, epistaxis, haemoptysis, palpitations, chest pain and chronic cough. Examination revealed central cyanosis, digital clubbing, polycythaemia, partial ptosis of right eye, diplopia on right gaze and dilated right pupil. Examination of the chest revealed pectus excavatum but no cardiac murmurs were heard. Investigations revealed a solitary right pulmonary arteriovenous malformation with two feeder vessels which were successfully embolized surgically.

Introduction. The presentation of acute coronary syndrome (ACS) in young HIV patients may be atypical with different pathophysiological and clinical features. Acute coronary thrombosis, as a presentation of acute coronary syndrome in young patients with HIV, raises diagnostic and treatment challenges. Case Presentation. We describe a case of a 33-year-old African man, without traditional atherosclerotic risk factors, who presented with chest pain of acute onset. Emergent coronary angiography revealed extensive thrombus in the left anterior descending coronary artery with no evidence of atherosclerosis in this or other coronary vessels. Plaque and/or thrombus prolapse through the stent was noted following percutaneous coronary intervention (PCI). Resolution of chest pain and improvement in ST-segment elevation was noted after the procedure. A diagnosis of HIV infection was made during the workup for HIV infection. Conclusion. In young patients without traditional risk factors, HIV infection is a possible etiological factor for spontaneous coronary artery thrombosis. Percutaneous coronary intervention in patients with this presentation may be compounded with atherothrombotic complications. The likely pathophysiological pathway is superficial endothelial cell denudation as a result of chronic inflammation and immune activation.

Patients with pectus excavatum (PEX) may be referred for echocardiographic examination for a variety of complaints including exercise intolerance, dyspnea, palpitations, or chest pain. It is therefore important for the echocardiographer to have an appreciation of the various abnormalities associated with this disorder. Echocardiographic imaging may reveal a number of structural alterations of the right ventricle as well as a reduction in right ventricular systolic function. Interestingly, a number of these abnormalities have also been described in patients with arrhythmogenic right ventricular dysplasia, although patients with PEX do not share a predilection for malignant ventricular arrhythmias. Additional echocardiographic abnormalities associated with PEX include prolapse of the mitral and/or tricuspid valves, Marfan's aortopathy, pericardial effusion, prominence of the crista terminalis, and possibly a number of congenital cardiac anomalies. This review discusses the echocardiographic abnormalities associated with PEX and their pathophysiologic significance. The effects of corrective orthopedic surgery on cardiac function are also discussed.

Congenital atresia of the left coronary artery is a very rare condition. We report a case of a 13-year-old boy who was followed-up at our outpatient clinic from 6 months of age because of heart murmur. He had no symptoms for more than 10 years, and his left ventricular contraction was normal. Exercise electrocardiogram was performed at 7 and 10 years of age, and ST depression was not observed. He presented with chest pain and syncope on exertion at the ages of 11 and 12 years, respectively, and ST depression on exercise electrocardiogram was detected for the first time at 13 years of age. Cardiac echocardiography showed a high-choic antero-lateral papillary muscle of the mitral valve, prolapse of the mitral anterior leaflet, and mild mitral valve regurgitation. Coronary angiography did not demonstrate antegrade left coronary flow or dilation of the right coronary artery. We performed coronary artery bypass grafting using the left internal thoracic artery. Postoperatively, the ST depression resolved, and his exercise tolerability improved.

Mitral valve prolapse (MVP) is characterized by typical fibromyxomatous changes in the mitral leaflet tissue with superior displacement of one or both leaflets into the left atrium. An echocardiogram is a fundamental study required for the diagnosis of MVP with a flail leaflet and grading of mitral regurgitation (MR) severity. Most patients with MVP have a risk of cardiovascular morbidity and mortality similar to that of the general population, though moderate to severe MR and left ventricular (LV) ejection fraction less than 50% have been postulated to increase the risk of adverse cardiac events. In this case report, we present an isolated flailed P3 scallop of the mitral valve leaflet leading to severe MR and acute congestive heart failure. A 54-year-old African-American male with a medical history of hypertension, hyperlipidemia, and transient ischemic attack, presented to the emergency department (ED) for evaluation of dyspnea on exertion. The patient reported that his dyspnea started one week prior to ED visit and was associated with intermittent chest pain. He also endorsed mild orthopnea and lightheadedness, though he denied any syncopal event. Vital signs were found within normal limits on arrival. He clinically appeared to be volume overloaded which improved quickly with IV furosemide. Transesophageal echocardiogram (TEE) with 3D image acquisition showed significant for hyper-dynamic LV function and evidence of isolated flailed P3 scallop of the mitral valve (MV) leaflet resulting in a severe eccentric, anteriorly directed MR jet. The MV leaflets did not appear thickened, and there was no evidence of mitral or aortic stenosis. Cardiac catheterization showed multivessel disease for which the patient underwent coronary artery bypass grafting and MV repair. This patient presented with new-onset congestive heart failure secondary to severe MR associated with undiagnosed MVP. Commonly, the middle scallop (P2) of the posterior leaflet is more prone to prolapse due to its redundancy and variable thickness with the impact of greater systolic pressure. However, in this case of acute severe MR, we identified an isolated flail of the P3 segment. We believe that this rare TEE finding was associated with a torn chordae or ruptured papillary muscle secondary to ischemic disease as the posteromedial papillary muscle has a single blood supply and is particularly prompted to injury from myocardial infarction.
