AIMS To evaluate the outcome following transarterial chemoembolization (TACE) and to identify the predictors of survival in patients with unresectable hepatocellular carcinoma (HCC). MATERIAL AND METHODS HCC patients reporting to our hospital (2001-2007) were subjected to clinical, biochemical, and radiological examination. TACE was performed in those who… (More)
This paper represents the lowest growth temperature for silicon nano-wires (SiNWs) via a vapour-liquid-solid method, which has ever been reported in the literature. The nano-wires were grown using plasma-enhanced chemical vapour deposition technique at temperatures as low as 150°C using gallium as the catalyst. This study investigates the structure and the… (More)
Langerhans Cell Histiocytosis (LCH) is a spectrum of disorders characterized by accumulation of histiocytes in various tissues. It is rarely encountered in ophthalmic practice and has an affinity for the orbit. We report three patients with LCH involving the lateral orbital wall, each with a different form of the condition.
The work described in this paper focuses on the utilisation of silicon nanowires as the information storage element in flash-type memory devices. Silicon nanostructures have attracted attention due to interesting electrical and optical properties, and their potential integration into electronic devices. A detailed investigation of the suitability of silicon… (More)
BACKGROUND Extrahepatic portal venous obstruction (EHPVO) is the most common cause of pediatric portal hypertension. We analyzed the investigative protocol and results of portosystemic shunts in this group of patients. MATERIALS AND METHODS A total of 40 consecutive children aged below 12 years operated with a diagnosis of extra-hepatic portal… (More)
We report a case of embryonal orbital rhabdomyosarcoma (RMS) in a five year old boy. Immuno-histochemistry of incisional specimen confirmed diagnosis. Eight cycles of chemotherapy along with radiotherapy resulted in over 50% reduction in size of the mass. However, increase in size was noted subsequent to completion of therapy and exenteration was deemed… (More)
Spinal dysraphism is a general term which encompasses a wide variety of anomalies of the spine, all of which result from imperfect midline fusion of the embryonic neural tube. This term refers to large defects that involve the spine and not to small vertical clefts commonly seen within the spinal process of L5 or S1. We present a spectrum of MR imaging… (More)
