Intrathoracic Ewing's sarcoma in an adult masquerading as lung abscess.

Intrathoracic extraskeletal Ewing's sarcoma (EES) is a relatively uncommon malignant tumour. Here, we present a scenario involving an adult man in his 20s with a large intrathoracic EES that manifested as a lung abscess. Preoperative diagnostic tests were inconclusive; hence, the patient underwent an exploratory thoracotomy for the excision of the mass. Histopathology revealed a small round blue cell tumour, and immunohistochemistry, along with fluorescence in situ hybridisation, confirmed the diagnosis of Ewing's sarcoma. Adjuvant chemoradiotherapy was recommended, but the patient did not comply. A year later, he presented with a recurrence of the intrathoracic mass and subsequently received adjuvant chemotherapy. Currently, he is in remission.

Successful management of delayed postoperative lung collapse secondary to spillage of aspergilloma.

Aspergilloma usually grows in lung cavities, although some may present with intrabronchial masses. Bronchial spillage during surgery is a known and disastrous complication of cavitary aspergilloma with bronchial communication. We present a case of a man in his 40s who developed a cavitary aspergilloma with recurrent haemoptysis almost a decade after his pulmonary tuberculosis. Following a segmentectomy for the same, the patient was extubated on table with well-expanded lung fields. Six hours later, he developed respiratory distress, and X-ray showed a complete lung collapse. An emergency bronchoscopy revealed a fungal ball obstructing the left main bronchus. The mass was successfully removed through bronchoscope, and the patient had lung expansion and uneventful recovery.

Successful Management of Aorto-Oesophageal Fistula Following Accidental Ingestion of Chicken Bone.

Accidental ingestion of foreign bodies is common in clinical practice. It is usually seen to pass through the gastrointestinal tract easily. However, in the case of impaction in the esophagus, it can lead to catastrophic conditions. Aorto-esophageal fistula is one such disastrous complication with a high fatality rate. Despite treatment, mortality rates of up to 80% have been reported in the literature, with the condition being uniformly fatal in untreated patients. We describe a case of aorto-esophageal fistula secondary to a chicken bone impaction presenting with sentinel hemorrhage and managed expeditiously and successfully with simultaneous endoscopic removal and surgical repair of the fistula.

An Unusual Presentation of a Completely Transected Aorta Presenting As Acute Limb Ischemia With Intramural Thrombus.

Contrast-enhanced multidetector computed tomography is currently the preferred imaging modality to diagnose acute traumatic aortic injury (ATAI). Rarely, ATAI can present with atypical findings that make the diagnosis and further management exceptionally challenging. Furthermore, ATAI can also be associated with inferior vena cava injury showing only indirect signs on later imaging. We present an unusual case of traumatic aortic disruption mimicking acute limb ischemia.

Survival of left ventricular rupture post mitral valve replacement.

A fatal and uncommon complication after mitral valve replacement is left ventricular (LV) rupture. We describe a case of a woman in her 40s with rheumatic heart disease and mitral regurgitation who underwent mitral valve replacement on cardiopulmonary bypass and experienced LV rupture but survived this catastrophe.

Extra-cardiac collateral to an anomalous origin right coronary artery in a post-PTCA, post-CABG patient.

In the context of collateral circulation of the heart, the role of extra-cardiac collateral arteries has been thought to be negligible. We present a case in which such collateral vessel acted as a rescue, subsequent to a failed revascularisation attempt. With surgeons nowadays considering 'less is more' in terms of grafting in coronary artery bypass grafting (CABG), and more evidence arising in favour of medical therapy, we need to re-assess the role of these collateral vessels in the coronary circulation.

Undiagnosed bilateral complete cervical rib with subclavian artery aneurysm presenting as acute ischaemic limb following high-altitude expedition.

Arterial thoracic outlet syndrome is relatively rare and often exclusively seen in the presence of bony anomalies. High-altitude (HA) travel is commonly associated with thrombosis; however, arterial thromboembolism is less frequently described. We describe a case of a young man with undiagnosed bilateral cervical rib, who went for an HA trek, subsequent to which developed acute limb ischaemia of right arm. Diagnostic workup revealed a subclavian artery aneurysm as well along with complete bony bilateral cervical ribs. Thoracic outlet syndrome should be kept as a differential diagnosis in a case of acute limb ischaemia in a healthy adult.

Mechanophysiologically active patch for closure of atrial septal defect.

Closure of atrial septal defects (ASDs) can be achieved by various methods right from direct closure to patch closure using various materials viz. pericardium, Dacron and Teflon, to device closure using percutaneous techniques. Although percutaneous techniques are the most commonly practised method in developed countries, a subset of patients will require surgical closure. Various patch materials have been used for long, but all of them have some complications and risks associated with them. We report a case of novel technique of ASD closure done using a pedicled, vascularised and contractile right atrial wall flap.

Lipid profile of Indian children and adolescents.

Dyslipidaemia when diagnosed in childhood predicts the development of clinical atherosclerotic disease in adulthood. Ever since we became aware of the abnormally high incidence of coronary artery disease amongst Indians, there always has been an ever-growing need for study of lipid values amongst Indian children and adolescents. Five hundred and eighty-six children (352 boys and 234 girls) from a public school aged between 8 and 18 years (mean age: 12.86 for boys and 12.15 for girls) were included in the study for assessment of lipid profile during the period from April, 1999 to March, 2000. Fasting venous blood was drawn from each child and total cholesterol and triglyceride levels were measured by enzymatic method, high-density lipoportein (HDL)-cholesterol was measured using specific precipitation method and lipoprotein (a) [Lp (a)] was measured by immunoturbidimetric method. After biochemical estimation was completed reference values and percentiles were calculated for each lipid component. Mean cholesterol and triglyceride values were higher amongst girls compared to boys. HDL-cholesterol values were lower amongst Indian boys compared to girls. Mean Lp (a) values were higher amongst both Indian boys and girls and more so amongst girls compared to boys. Since Lp(a) values remain unchanged through ages, these values should represent corresponding values in adult Indian males and females. It is being expected that data presented in this study should form guidelines with regard to dietary and pharmacological intervention for dyslipidaemia amongst children and adolescents.
