A study on genetic polymorphism of RET proto-oncogene in Hirschsprung's disease in children.

Background: Hirschsprung's disease (HD) is a genetic disorder with a complex pattern of inheritance. Some single-nucleotide polymorphisms (SNPs) are identified to be associated with the risk of Hirschsprung's Disease (HSCR).

Aims And Objectives: The aim of this study is to know the association between the rearranged during transfection (RET) proto-oncogene polymorphism and HD and to characterize the SNPs of RET proto-oncogene affecting HD.

Changes in Different Cytokines (IL-2, TNF-α, and IFN-γ) Profile in Acquired Aplastic Anemia Patients: A Study From Eastern India.

Although aplastic anemia has been extensively investigated, little is known about their circulating cytokine pattern. The present study was done to evaluate the severity of the disease with the 3 major anti-hematopoietic cytokines interleukin-2 (IL-2), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ). This study is ethically cleared.

Incidence of Fanconi anaemia in phenotypically normal aplastic anaemia patients in West Bengal.

Objectives: Fanconi anaemia (FA) is a rare inherited bone marrow failure and autosomal recessive blood disorder. FA patients have a higher risk of cancer, including acute myeloid leukaemia and squamous cell carcinoma. Maximum, but not all, affected individuals have one or more somatic abnormalities, including skin, skeletal, genitourinary, gastrointestinal, cardiac and neurological anomalies, etc.

Cytogenetic study is not essential in patients with aplastic anemia.

Depending on contemporary treatment approach of aggressive immunosuppression, Aplastic Anemia (AA) is caused by immunological destruction of otherwise normal hematopoietic stem cells. The aim was to summarize the cytogenetic abnormalities in AA patients and the frequency of Fanconi Anemia (FA) in morphologically normal AA patients in eastern India. Ethical clearances were obtained from both institutions involved in this study.

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).

Eccrine angiomatous hamartoma: late onset facial presentation.

Eccrine angiomatous hamartoma (EAH) is a very rare benign neoplastic condition characterized by hamartomatous proliferation of eccrine glands and accompanying blood vessels and lymphatics. These lesions are more often present at birth or appear during early infancy and childhood and present as solitary nodule or plaque with occasional pain and sweating. They are generally present on the extremities, mostly the palms and soles.

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.

Impact of iron deficiency anemia on cell-mediated and humoral immunity in children: A case control study.

Objective: The precise role of iron in immune regulation especially in children vulnerable to iron deficiency is not fully known. Hence, this study was conducted to evaluate the effects of iron deficiency anemia (IDA) and its treatment with oral iron supplementation on cell-mediated immunity (CMI) and humoral immunity (HMI) in children.

Materials And Methods: A total of 40 children (<15 years) with IDA and 40 age-matched healthy children after satisfying the inclusion criteria were enrolled for this case-control study.

Endometrial hyperplasia: a clinicopathological study in a tertiary care hospital.

Objective: To evaluate the clinical as well as histomorphologic features in different cases of endometrial hyperplasia along with its relative occurrence.

Materials And Methods: A one-and-a-half-year prospective study was conducted on histopathologically diagnosed cases of endometrial hyperplasia in a tertiary care hospital. Apart from relevant clinical findings, histomorphologic details were noted and statistically analyzed.

Eccrine angiomatous naevus revisited.

Hamartomatous, circumscribed swellings of the extremities make an interesting study. Presentations are manifold and the naevi are not always present from birth. Excessive growth of hairs leads to remarkable appearance of such swellings.

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.

A locally developed snakebite management protocol significantly reduces overall anti snake venom utilization in West Bengal, India.

Objective: The purpose of this study was to determine the impact of a nationally developed snakebite treatment protocol on the amount of anti snake venom (ASV) used in treating snakebites in a developing country and its effect on mortality. In addition, basic epidemiology data were collected and analyzed.

Methods: Experts in Indian snakebites developed a protocol specifically designed for snakebite treatment in India.

A clinicopathological study of malignant melanoma with special reference to atypical presentation.

Malignant melanoma is a tumor of melanocytic origin. Lymphatic and hematogenous metastases are common in this condition. Retrospective analysis was performed in 16 consecutive cases diagnosed histopathologically as malignant melanoma at the pathology department of a medial college in eastern India.

CT guided fine needle aspiration cytology of thoracic mass lesions: a prospective study of immediate cytological evaluation.

To evaluate the role of CT guided FNAC as diagnostic and supportive investigation for thoracic lesions, 190 patients were studied during two years period from March 2003 to February 2005 in our institution. A total number of 163 (85.8%) lung lesions, 22 (11.

A study of fine needle aspiration cytology of salivary gland lesions with histopathological corroboration.

The diagnostic utility of fine needle aspiration cytology as initial work up of salivary gland enlargement was assessed in one hundred and eighty-five salivary gland specimens over three years period and corroborated with histopathology, whenever feasible. All smears were evaluated according to cell size, amount of cytoplasm, cytologic atypia and presence of lymphocytes. (a) Variable cytologic appearances of pleomorphic salivary adenoma were observed.
