Thyroid Cancer Screening Using Tumor-Associated DN T Cells as Immunogenomic Markers.

Background: Thyroid nodules are an extremely common entity, and surgery is considered the ultimate diagnostic strategy in those with unclear malignant potential. Unfortunately, strategies aiming to predict the risk of malignancy have inadequate specificity. Our group recently found that the microenvironment of thyroid cancer is characterized by an enhanced immune invasion and activated immune response mediated by double-negative T lymphocytes (DN T) (CD3CD4CD8), which are believed to enable or promote tumorigenesis.

Hyponatraemia: Epidemiology and aetiology in a tertiary care centre in Pakistan.

Objective: To determine the incidence, aetiology and epidemiology of hospitalized patients with hyponatraemia.

Methods: Subjects were identified through hospital information system for two consecutive low sodium values (< 130 mEq/L) and charts were reviewed retrospectively. Possible etiologic factors were identified and co-morbidities documented.

IgG4-related retroperitoneal fibrosis: A case report and review of literature.

Idiopathic Retroperitoneal fibrosis is a rare clinical condition recently identified as an autoimmune process related to Immunoglobulin G4 (IgG4) deposition. Herein we report a case of a 46 year old male presenting with 4 months history of backache, fever, flank pain and leg swelling for 2 weeks. Investigations revealed acute kidney injury diagnosed as a result of bilateral ureteric obstruction.
