BACKGROUND: A high rate of association between neuroendocrine tumors (NETs) and secondary primary malignancy (SPM) has been described in literature and this association can occur either in a synchronous or a metachronous presentation. A wide range of hypothesis has been postulated to explain the high rate of association between NETs and SPM, without definitive conclusions. CASE PRESENTATION: We report a case of an ileal neuroendocrine tumor found incidentally at the histologic examination of the surgical specimen in a 72 years old male underwent to right hemi colectomy for two colic adenomatous polips with high grade dysplasia...

INTRODUCTION: Primary anorectal malignant melanoma is a rare and aggressive tumor that carries a poor prognosis. Anorectal melanoma (ARM) is often misdiagnosed as hemorrhoids adenocarcinoma polips and rectal cancer. ARM spreads along sub-mucosal planes and is often to wide-spread for complete resection at time of diagnosis and almost all patients die because of metastases. PRESENTATION OF THE CASE: A 77-year-old male patient presented a history of recurrent rectal bleeding and whose histopathological diagnosis was melanoma...

INTRODUCTION: Chromosomal abnormalities are the results of alterations in the number or structure of chromosomes causing significant human morbidity and mortality. They are responsible for a large proportion of miscarriages, developmental delay, disorders of sexual development, congenital malformations and mental retardation. AIM: The aim of this study was to describe the prevalence of different chromosomal abnormalities in North Indian patients referred for cytogenetic analysis...

STUDY OBJECTIVE: To highlight the first case of laparoscopic hysterectomy performed with percutaneous instruments (The Percuvance System, Teleflex Incorporated, Wayne, PA). DESIGN: The basis of the system is a <3-mm diameter shaft that, when connected to an introducer tool tip, can be inserted percutaneously through the skin. The introducer tool tip can then be exchanged outside the body for a wide variety of 5-mm interchangeable surgical tool tips. The shaft is sufficiently strong to hold structures, and surgeons can use its interchangeable tool tips to grasp, cut, and manipulate tissue...

Interleukine-18 (IL-18) was originally called interferon (INF-γ) inducing factor and plays a critical dual role in Th1 polarization and viral clearance. We aimed to explore whether single-nucleotide promoter polymorphisms (SNPs) are associated with the outcome of hepatitis B virus (HBV) infection. 271 HBV infected patients were recruited in this study out of these 109 were spontaneously recovered and 162 were diagnosed to be having persistent HBV infection which includes 48 chronic hepatitis, 84 liver cirrhosis, 30 HCC cases and were compared with 280 healthy controls...

BACKGROUND: Interleukin-18 (IL-18) is a pro inflammatory cytokine which plays a key role in the acute and chronic inflammatory phases of Rheumatoid Arthritis (RA). The Single Nucleotide Polymorphisms (SNPs) of IL-18 gene promoter region at positions -137 and -607, are postulated to be associated with RA. To test this, this study aimed to identify the association between these SNPs of the IL-18 gene promoter region of RA in south Indian patients. MATERIALS AND METHODS: This study was carried on 190 subjects among which 90 were RA patients and 100 were age and sex matched controls...

BACKGROUND AND AIM: Osteoporosis (OP) is a common nutrigenomic disease associated with various genetic components. Observational studies have indicated that mildly elevated homocysteine was a strong risk factor for osteoporotic fractures. Yet there is no clear biologic mechanism for an effect of homocysteine on bone.The aim of this study was to investigate the association of MTHFR C677T and A1298C polymorphisms, and to verify the association of these polymorphisms with bone mineral density and homocysteine in premenopausal women of northern India...

AIMS AND OBJECTIVE: Evaluation of C677T polymorphisms of the methylenetetra hydrofolate reductase (MTHFR) gene and its association with level of serum homocysteine, folate, and vitamin B12 as possible maternal risk factors for Down syndrome.

MATERIAL AND METHODS: Fifty-two mothers (mean age 27.6 years) with babies having free trisomy 21 of North Indian ethnicity and 52 control nonlactating mothers (mean age 24...

Duodenal tumors are very rare tumors, with the lower incidence among the tumors of the small bowel, whose frequence is less than 5 % of all digestive tumors. In most of the cases these tumors remain asymptomatic, sometimes the entire life. When they become symptomatic, their first manifestation is the loss of digested blood (melena), secondary anemia and obstructive symptomatology. Early diagnosis of these tumors is difficult because of the unsystematic symptomatology and becomes easy when the complications appear...

BACKGROUND & OBJECTIVES: Hepatitis E is the main cause of enterically transmitted non-A, non-B hepatitis in developing countries. In the developed countries such as the USA, Japan and Taiwan, the viruses infecting humans and swine share the same genotype with a high sequence similarity. Genotype 1 circulates in humans whereas genotype 4 in pigs in India. The present study was designed to investigate the presence of anti-HEV antibodies and HEV-RNA in swine population from north India, to investigate the genotype prevalent in it, and to compare it with other swine and human HEV strains from India...
