EBV-triggered secondary macrophage activation syndrome in the backdrop of lupus in an adult.

Macrophage activating syndrome (MAS) is a potentially life-threatening condition falling under the spectrum of secondary hemophagocytic lymphohistiocytosis, in the backdrop of rheumatological conditions. In this case of a middle-aged man, we see how an initial Epstein Barr virus infection triggered a chain of events, which after serial monitoring of labs was promptly diagnosed as MAS and treated appropriately, resulting in overall clinical improvement of the patient.

TACE inhibition: a promising therapeutic intervention against AATF-mediated steatohepatitis to hepatocarcinogenesis.

Metabolic dysfunction-associated steatohepatitis-driven hepatocellular carcinoma (MASH-HCC) is a global clinical challenge for which there is a limited understanding of disease pathogenesis and a subsequent lack of therapeutic interventions. We previously identified that tumor necrosis factor-alpha (TNF-α) upregulated apoptosis antagonizing transcription factor (AATF) in MASH. Here, we investigated the effect of TNF-α converting enzyme (TACE) inhibition as a promising targeted therapy against AATF-mediated steatohepatitis to hepatocarcinogenesis.

Glomerular parietal epithelial expression of CD44 in minimal change nephrotic syndrome and primary focal segmental glomerulosclerosis: A clinico-pathological study.

Introduction: Minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS) are the two common causes of nephrotic syndrome (NS) in both children and adults with overlapping clinical features, but with distinct prognostic and therapeutic implications. The distinction between these relies entirely on histopathology, which can sometimes be difficult. CD44 is expressed by activated parietal epithelial cells, plays a role in matrix deposition and thus in the pathogenesis of FSGS.

AATF inhibition exerts antiangiogenic effects against human hepatocellular carcinoma.

Background And Aims: Angiogenesis is a key factor in the growth and metastasis of hepatic tumors and thus a potential therapeutic target in hepatocellular carcinoma (HCC). In this study, we aim to identify the key role of apoptosis antagonizing transcription factor (AATF) in tumor angiogenesis and its underlying mechanisms in HCC.

Methods: HCC tissues were analyzed for AATF expression by qRT-PCR and immunohistochemistry.

Pleomorphic adenoma of the external auditory canal.

Pleomorphic adenoma (PA) of the external auditory canal (EAC) is a rare clinical entity with a few cases reported in the literature. The clinical diagnosis of these lesions can be formidable due to their rarity and unusual location. This tumor occurs at various other anatomical locations apart from the major salivary glands.

Unraveling the Potential Role of in Experimental NASH.

The pathophysiology of nonalcoholic steatohepatitis (NASH) is complex, owing to its diverse pathological drivers and, until recently, there were no approved drugs for this disease. is a popular herbal medicine used to treat hepatosplenomegaly, hepatitis, and obesity. However, the potential role of in NASH has not yet been scientifically investigated.

Thrombotic microangiopathy with pulmonary hemorrhage: A rare case report.

Thrombotic microangiopathy (TMA) includes various diseases with different etiologies which ultimately results in endothelial damage to the small vasculature leading to thrombosis in the micro vessels, this causes mechanical hemolysis, thrombocytopenia due to platelet consumption and ischemic organ damage. Untreated cases carry high mortality, so identifying the cause for TMA assumes importance. We report a 47-year old hypertensive lady presenting with accelerated hypertension (HTN) and TMA picture with rapidly progressive renal failure.

A clinico-pathological study of lupus nephritis based on the International Society of Nephrology-Renal Pathology Society 2003 classification system.

Introduction: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN.

Ki-67 immunostaining in astrocytomas: Association with histopathological grade - A South Indian study.

Background: Astrocytomas are the most common primary tumor of the central nervous system. The distinction between different tumor grades can be tested despite criteria given by the World Health Organization (WHO). Ki-67 is a potent biological marker used in grading of astrocytomas, which estimates growth of the neoplasm quantitatively and will help in predicting prognosis accurately.

Comparison of Cell Preparations between Commercially Available Filter Cards of the Cytospin with Custom Made Filter Cards.

Introduction: Cytological evaluation of body fluids is an important diagnostic technique. Cytocentrifuge has contributed immensely to improve the diagnostic yield of the body fluids. Cytocentrifuge requires a filter card for absorbing the cell free fluid.

Cannonballs in Pap Smears: Double Whammy of Bacterial Vaginosis and Associated Infections.

Introduction: Cannonballs are structures consisting of neutrophils adherent to epithelial cells, often seen in vaginal Pap smears of patients with trichomoniasis and chlamydiasis. We frequently observed these cannonballs in inflammatory Pap smears showing evidence of bacterial vaginosis.

Objective: To study the association between cannonballs and bacterial vaginosis with associated infections in inflammatory Pap smears.

Myxoinflammatory fibroblastic sarcoma of the thigh: A morphologic diversity.

Myxoinflammatory fibroblastic sarcoma (MIFS)/acralmyxoinflammatory fibroblastic sarcoma (AMFS) is a rare, painless, low-grade neoplasm which commonly occurs in the extremities. It has a distinctive morphology and can be a diagnostic challenge, simulating inflammatory conditions as well as neoplastic conditions. They are low-grade sarcomas with a protracted clinical course, a high rate of local recurrence and a low rate of metastasis.

Fine needle aspiration cytology of pseudosarcomatous reactive lesions of soft tissues: A report of two cases.

Pseudosarcomatous lesions are reactive proliferative lesions of the soft tissue, that are likely to be misdiagnosed as malignant, based on clinical and histological features. The most common lesions are nodular fasciitis, proliferative fasciitis, proliferative myositis and myositis ossificans. These rapidly growing soft-tissue lesions can represent a variety of diagnoses involving radically different treatment modalities.
