Pattern of autologous stem cell transplants at a tertiary care government hospital, with emphasis on transplant outcomes with pre-harvest CD34+ level.

Purpose: Autologous stem cell transplantation (ASCT) is an established therapy for many hematological diseases. This study assessed the pattern of ASCTs at a tertiary care center and associated factors, including pre-harvest CD34+ stem cell levels, leading to improved engraftment outcomes.

Methodology: A retrospective study was conducted in India, between February 2009-August 2020.

Expression of CDX-2 and Ki-67 in different grades of colorectal adenocarcinomas.

Background: CDX2 is a caudal homeobox gene essential for intestinal differentiation and is specifically expressed in colorectal adenocarcinomas. Its role in colorectal carcinogenesis is not fully elucidated.

Aims And Objectives: To study the expression pattern of CDX2 and Ki-67 in different grades of colorectal adenocarcinomas and to observe the relationship of their staining patterns in various tumor stages and to look for correlation if any, between Ki-67 labeling index (Ki-67 LI) and CDX2 expression.

Spectrum of Hemoglobinopathies in West Bengal, India: A CE-HPLC Study on 10407 Subjects.

Hemoglobinopathies are common genetic disorders of haemoglobin. Identification of these disorders is immensely important epidemiologically and they can be prevented by population screening. The present study was carried out to evaluate the spectrum of hemoglobinopathies in the state of West Bengal by the cation-exchange high-performance liquid chromatography (CE-HPLC).

Amoeboma of colon mimicking colonic carcinoma.

Entamoeba histolytica is a major cause of diarrhea in the developing countries and it can present with a wide range of gastrointestinal symptoms depending on the phase of the infection. We describe a case of 65-year-old male patient presented with abdominal pain and vomiting. On the clinical and radiological examination provisional diagnosis of colonic carcinoma was suspected.

Analysis of FNAC of cervical lymph nodes: experience over a three-year period.

This study was taken up with the aim to investigate the pattern of cervical lymphadenopathy among patients presenting to IPGME&R, Kolkata, a tertiary care institution in Eastern India to evaluate the diagnostic efficacy of FNAC, and to dissect the diagnostic pitfalls. A total of 509 patients were subjected FNAC of cervical lymph nodes over a three-year period (August 2006-July, 2009). Since in 34 patients, as either the aspirate was inadequate or the opinion equivocal, the remaining 475 cases were analysed.

Morphometric and histological study of breast lesions with special reference to proliferative activity and invasiveness.

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.

Effect of chloride on the dissolution rate of silver nanoparticles and toxicity to E. coli.

Pristine silver nanoparticles (AgNPs) are not chemically stable in the environment and react strongly with inorganic ligands such as sulfide and chloride once the silver is oxidized. Understanding the environmental transformations of AgNPs in the presence of specific inorganic ligands is crucial to determining their fate and toxicity in the environment. Chloride (Cl(-)) is a ubiquitous ligand with a strong affinity for oxidized silver and is often present in natural waters and in bacterial growth media.

Paraganglioma of the oropharynx.

Paraganglioma is a rare tumor in head and neck region. A 35 years male presented with huge swelling of tonsillar region occupying a large portion of oropharynx. Tumor had been dissected out transorally.

Fine needle aspiration cytology of supraclavicular lymph nodes: Our experience over a three-year period.

Aims: This study was taken up with the aim to investigate the pattern of supraclavicular lymphadenopathy among patients presenting to our tertiary care institution, evaluate the diagnostic efficacy of fine needle aspiration cytology (FNAC), and analyze the diagnostic pitfalls.

Materials And Methods: A total of 215 patients were subjected to FNAC of supraclavicular lymph nodes over a three-year period (August 2006 to July 2009). Since in 18 patients as either the aspirate was inadequate or the opinion was equivocal, we analyzed the remaining 197 cases.

Squash preparation: A reliable diagnostic tool in the intraoperative diagnosis of central nervous system tumors.

Background: Intraoperative cytology is an important diagnostic modality improving on the accuracy of the frozen sections. It has shown to play an important role especially in the intraoperative diagnosis of central nervous system tumors.

Aim: To study the diagnostic accuracy of squash preparation and frozen section (FS) in the intraoperative diagnosis of central nervous system (CNS) tumors.
