Balantidium coli (B. coli) is the only trophic ciliate of low virulence causing dysentery in human. However, may be due to their active motility and invasive nature, they have been rarely described to cause infection in extraintestinal sites also. We herein describe a case where trophozoites of B. coli were detected in urinary sediment examination of an elderly female presenting with mild fever, dysuria and hematuria for last 1 week. The parasites were identified by their characteristic morphology and rapid spiraling motility. This is only the third case described in literature to detect B. coli in urine sediment.

Context:The birth of transfusion-dependent states of hemoglobinopathies including thalassemias is preventable by population screening and genetic counseling. Magnitude is not addressed in the Northern Region of West Bengal where many ethnic variants inhabit.Aims and Objectives:The aim of the following study is to find out the burden of different entities of hemoglobinopathies, their correlation with ethnicity and the “at risk” groups.Subjects and Methods:A descriptive study was conducted from the Hematology Unit of North Bengal Medical College over 1 year on the subjects underwent screening for hemoglobinopathies for detection of abnormal hemoglobin (Hb) variants by “cation-exchange high-performance liquid chromatography” principle along with other relevant tests.Statistical Analysis:Data was analyzed by frequency distribution and Chi-square test assuming P value as 95% of the level of significance using the SPSS version 16 (SPSS Inc., Chicago, Illinois, U.S.A).Result:Abnormal Hb variant was 47.5% among 1872. Hb E trait (34.4%) was most common followed by Hb E disease (25.3%) and others. Hb E disorders (92.7%) were observed mostly among Rajbangsi population while E-β-thalassemias (40%) in the Muslims and a heterogeneous pattern noted among tribal and mongoloid.Conclusion:Hb E hemoglobinopathies was high among Rajbangsi and Muslims with identification of some other hemoglobinopathies involving tribal and mongoloid.

Molluscum contagiosum (MC) is caused by a double stranded DNA virus belonging to the pox virus family. MC lesions are usually pearly, dome shaped, small, discrete lesions with central umbilication. In HIV-positive patients atypical varieties are found. They may be large or nonumbilicated. Individual papules may join to form the agminate variety. This form is rare. Lesions of MC in healthy immunocompetent patients may occur at any part of the body including face, trunk, and limbs. Sexually active adults have lesions usually on the genitalia, pubis, and inner thigh, rarely on the face and scalp. We present a case of agminate MC occurring in a patient with acquired immunodeficiency disease responding to highly active antiretroviral therapy.

Primary hydatid cyst of the neck is of extremely rare occurrence even in endemic regions. Clinically mimicking a cold abscess, we report such a case which was diagnosed by fine needle aspiration cytology. The lesion was removed surgically and at 6-month follow-up visit, the patient was a symptom-free.

Purpose of study A prospective study was done at North Bengal Medical College and Hospital (NBMCH), Darjeeling, West Bengal, which caters predominantly to the rural and hilly population. All patients diagnosed as Hodgkin's lymphoma (HL) were analyzed for clinical presentation, histological classifi ed and staging.Results Total of 48 cases reported for HL were studied (n=48). A lower median age of onset (28.1year) and higher male to female ratio (3.8:1) as compared to western countries were observed. We found neck swelling was the commonest presenting symptom (58.28%) and peripheral lymphadenopathy was the commonest sign (83.33%). "B symptoms" was noted in 79.17% cases. Cervical lymph nodes were commonly involved (79.17%), followed by inguinal (45.83%) and axillary (29.17%). Thoracic lymph nodes and abdominal lymph nodes were enlarged in 29.17% of the cases and 25% of the cases respectively. Eosinophilia was noted in 29.17% of cases. Marrow involvement by neoplastic process was observed in 8.33% of cases and reactive changes in the marrow were observed in 12.5% of cases.We found mixed cellularity subtypes was the commonest (45.83%) followed by nodular sclerosis subtypes (33.33%). At presentation 54.17% of cases were of advanced stage of disease (stage III and IV). ConclusionWe noticed a distinct geographical pattern of HL in respect of age, sex, presentation, histological typing and staging of the disease, which is comparable to some other Indian studies but is noticeably different from patterns noted in Western countries.

Lymph node cytology in HIV-infected patients is essential to identify opportunistic infections from neoplastic lesions and; to enable therapeutic strategies. Correlation of lesions with mean CD4+ T-cell count predicts personal immunity, stage of disease and disease activity. Furthermore, enlarged lymph node numbers and ALC can be surrogate markers of CD4+ T-cell count for monitoring the severity of the immune suppression in under-resourced countries like India.
