1.  Surgical Repair of Congenital Abdominal Aortic Aneurysm in a 1-year-old Child with Literature Review 
Reported here is a case of 1-year-old male child who presented with huge abdominal mass, which on radiological investigation was diagnosed as retroperitoneal pseudoaneurysm of the aorta. On exploration, it was found to be a true aneurysm of infrarenal abdominal aorta with inflow agenesis. Aneurysm was excised, and aorta was reconstructed with 10 mm Dacron graft. Postoperative computed tomography angiography showed patent graft with good distal runoff. Literature review revealed that only 26 cases of congenital abdominal aortic aneurysm had been reported so far. None of them had inflow agenesis which can give false impression of pseudoaneurysm on preoperative evaluation. The case highlights the utility of additional complimentary investigations such as Doppler study in clinching diagnosis and helping plan and execute successful treatment in the difficult diagnostic scenario.

2.  Impacted Sharp Oesophageal Foreign Bodies—A Novel Technique of Removal with the Paediatric Bronchoscope 
Journal of Tropical Pediatrics  2016;62(2):161-164.
Sharp foreign bodies in the oesophagus may present as an entirely asymptomatic child with only radiological evidence but require emergent surgical management. Safety pins, razor blades and needles are a few of the commonly ingested sharp objects in developing countries. The open safety pin is a particularly interesting clinical problem, as the management depends on its location and orientation. Many methods and instruments have been used over the years to remove them from the upper digestive tract. We present a novel method using the rigid paediatric bronchoscope and alligator forceps for the extraction of this unusual foreign body from the oesophagus of a 6 year old girl.

3.  Maxillofacial Prosthetic Materials- An Inclination Towards Silicones 
There have been constant searches and researches which are taking place in the field of dental materials to best suit the ideal selection criteria to satisfy the functionality, biocompatibility, aesthetics as well as the durability as a maxillofacial material. Among all the different materials, Silicone is the most popularly used, but still studies are carried out to overcome their weaknesses and to come out with a material which can be labeled as the “ideal maxillofacial prosthetic material”. This article comprises the materials which were and are in use and the reason for their unpopularity. It also gives us a scope to understand the major fields where the materials lack and thus needs improvement to render an individual with the best maxillo-facial prosthesis.

4.  Morphometric and Histological Study of Breast Lesions with Special Reference to Proliferative Activity and Invasiveness 
The Indian Journal of Surgery  2012;75(3):204-209.
Breast carcinoma is the most common cause of carcinoma death in women. Sometimes, difficulty arises to differentiate between premalignant lesions and carcinoma by routine histopathology. Our study was done to establish the role of morphometry and immunohistochemistry to solve this problem. In this study, total 60 cases of different breast lesions were included and 10 controls were also included to compare the results with the normal findings. They were studied by hematoxylin and eosin-stained sections for morphometry and routine histological study; as well as by proliferative markers such as proliferating cell nuclear antigen and p53. Invasiveness was studied using immunohistochemical staining with 34 βE12 monoclonal antibody. Statistically significant differences were found in morphometric parameters and in expression of proliferative markers between most of them. Morphometry and immunohistochemistry help in the proper diagnosis of different breast lesions that lie in the gray zone on routine histopathology.

5.  Foxp3+ Regulatory T Cells among Tuberculosis Patients: Impact on Prognosis and Restoration of Antigen Specific IFN-γ Producing T Cells 
PLoS ONE  2012;7(9):e44728.
CD4+CD25+Foxp3+ Regulatory T cells (Treg) and programmed death-1 (PD-1) molecules have emerged as pivotal players in immune suppression of chronic diseases. However, their impact on the disease severity, therapeutic response and restoration of immune response in human tuberculosis remains unclear. Here, we describe the possible role of Treg cells, their M. tuberculosis driven expansion and contribution of PD-1 pathway to the suppressive function of Treg cells among pulmonary tuberculosis (PTB) patients. Multicolor flow cytometry, cell culture, cells sorting and ELISA were employed to execute the study. Our results showed significant increase in frequency of antigen-reactive Treg cells, which gradually declined during successful therapy and paralleled with decline of M. tuberculosis–specific IL-10 along with elevation of IFN-γ production, and raising the IFN-γ/IL-4 ratio. Interestingly, persistence of Treg cells tightly correlated with MDR tuberculosis. Also, we show that blocking PD-1/PD-L1 pathway abrogates Treg-mediated suppression, suggesting that the PD-1/PD-L1 pathway is required for Treg-mediated suppression of the antigen-specific T cells. Treg cells possibly play a role in dampening the effector immune response and abrogating PD-1 pathway on Treg cells significantly rescued protective T cell response, suggesting its importance in immune restoration among tuberculosis patients.

6.  Primary mesenteric liposarcoma: An unusual presentation of a rare condition 
Primary mesenteric liposarcoma is a rare neoplasm. Here, we report the case of a 50 year old Indian man with a pleomorphic liposarcoma of the mesentery. The clinical findings pointed towards a retroperitoneal growth but imaging resolved the issue. A laparotomy was performed and a 20 cm × 20 cm multilobulated tumour arising from the mesentery and weighing 1.8 kilograms was excised with a segment of jejunum. The cut surface had a variegated appearance with regions of necrosis. The histological features were suggestive of pleomorphic liposarcoma. Tumour cells were positive for S-100 and negative for SMA/Desmin. Complete resection is curative although the role of chemotherapy remains to be established.
