Endoscopic Monitoring of Treatment of Indeterminate Intestinal Lesions in a Prospective "Real-Life" Cohort in Eastern India Where Tuberculosis Remains Endemic: Distinguishing Intestinal Tuberculosis From Crohn's Disease.

Introduction It is sometimes difficult to differentiate between intestinal tuberculosis (ITB) and Crohn's disease (CD) in India, as both conditions may mimic each other. The aim was to differentiate ITB from CD in indeterminate intestinal lesions with a therapeutic trial of anti-tubercular therapy (ATT) and follow-up to find out the clinical, endoscopic, radiological, and histological predictors for differentiation between ITB and CD. Methods A prospective observational cohort study of patients diagnosed with ITB and CD according to the Asia-Pacific Guidelines in a "real-life" clinical setting was conducted.

MiT family translocation-associated renal cell carcinoma: A report of two cases in children.

Renal cell carcinoma is uncommon in children and must be distinguished from the more common Wilms' tumor. Here, we present two cases of renal cell carcinoma in children both of whom presented with hematuria. Accurate diagnosis is essential in order to differentiate it from epithelial predominant Wilms' tumor which has vastly different prognosis and treatment.

The curious case of T-cell mediated renal allograft rejection after Covid-19 infection.

Our case illustrates the possible explanation of renal allograft rejection in a patient who had recovered from Covid-19 infection in the post-transplant period, which ultimately led to the death of the patient. A 27-year-old male patient received renal allograft from his mother, with an uneventful post-transplant period. Three years after the transplantation he contracted Covid-19 infection.

Assessment and clinicopathological correlation of p16 expression in cervical squamous cell carcinoma of Indian population: Diagnostic implications.

Background: Our aim was to assess the p16 expression in normal cervical epithelium and cervical lesions and how it correlated with HPV oncoprotein E7 and other etiological parameters of cervical cancer.

Methods: For this purpose, we analyzed protein expression of p16 and E7 oncoprotein in total 20 normal cervical epithelium tissue (as control) and 62 cervical lesions. Next, the result was correlated with different clinico-pathological parameters.

Spectrum of renal vascular lesions among patients with lupus nephritis: An experience from a tertiary care center.

Background: Lupus nephritis (LN) is the assemblage of glomerular, tubulointerstitial and vascular changes. Despite the fact that glomerular changes are overemphasized in pathological classification and scoring system, but the existence of vascular damage negatively impact the clinical course.

Aims And Objective: This study was conducted to determine the clinicopathological spectrum of renal vascular lesions in lupus nephritis.

Heavy chain deposition disease in a case of clear cell renal cell carcinoma- A jack in the box.

Renal cell carcinoma (RCC) is the most common subtype of adult renal tumors, and its detection rate in the early stages has been increased in the dawn of advanced imaging modalities. Nephrectomy is the mainstay of treatment; determination of tumor category and staging is the primary concern of oncopathologists. Non-neoplastic renal parenchyma is overlooked majority of times and thus misses the opportunity to detect concomitant medical renal diseases which also predict the renal outcome in the postoperative era.

An Epidemiological Study of the Quality of Life of Children With Beta-Thalassemia Major (β-TM) and Its Correlates in Kolkata, West Bengal, India.

Background and objectives In contrast to their peers who are healthy, children with thalassemia disease are likely to have a lower quality of life (QoL). Knowledge of attributes affecting the QoL of thalassemic children may help identify key areas of intervention to improve it. Thus, the current study was envisioned to find out the quality of life (QoL) of children with beta-thalassemia major (β-TM) and its various correlates.

Utility of serum anti-phospholipase A2 receptor antibody as a biomarker in membranous nephropathy: An experience from a tertiary care center of Eastern India.

Three shades of black - secondary thrombotic microangiopathy.

Thrombotic microangiopathy is a group of disorders characterized by microangiopathic hemolytic anemia, thrombocytopenia and organ damage. Wide age distribution and the heterogeneity in presentation demand a deeper understanding into the pathogenesis of TMA. Primary TMA is distinct from TMA associated with secondary causes and remains clinically occult till a precipitating factor aggravates it.

Role of light and immunofluorescence microscopy to differentiate primary and secondary membranous nephropathy.

Context: Membranous nephropathy (MN) causes nephrotic syndrome, mostly primary but may be associated with SLE, infections, cancer, or drug.

Aims: To estimate clinical, serological, light microscopic, and direct immunofluorescence (DIF) findings to differentiate primary and secondary MN.

Settings And Design: Prospective, cross-sectional, single-center study in a tertiary care hospital.

Transfusion-transmitted infections, its risk factors and impact on quality of life: An epidemiological study among β-thalassemia major children.

Background: Multi-transfused thalassemic children are at higher risk of acquiring transfusion-transmitted infections (TTIs). There are limited data available on TTIs among thalassemic children, especially on its impact on their quality of life (QoL).

Aim: The aim of this study is to find out the proportion of multi-transfused β-thalassemia major (β-TM) children suffering from TTIs, its risk factors and impact on QoL.

Archived dengue serum samples produced false-positive results in SARS-CoV-2 lateral flow-based rapid antibody tests.

Co-endemicity of SARS-CoV-2 and dengue virus (DV) infection is becoming a matter of serious concern as it has been already reported that antibodies (Ab) elicited by SARS-CoV-2 infection can produce false-positive results in dengue IgG and IgM rapid tests and . Here we communicate that five of thirteen DV antibody-positive serum samples from Kolkata, archived in 2017 (predating the COVID-19 outbreak), produced false-positive results in SARS-CoV-2 IgG/IgM lateral flow-based rapid tests. Our results emphasize the importance of implementing tests with higher specificity to conduct sero-surveillance for accurate estimation of SARS-CoV-2/DV prevalence in regions where both viruses now co-exist.
