Tenosynovitis is the inflammation of the synovial sheath, the thin layer of tissue that surrounds tendons. It typically occurs in areas where tendons pass through narrow anatomical tunnels, particularly in the hands, wrists, feet, and ankles. The condition can result in pain, swelling, restricted movement, and in severe cases, tendon damage. Unlike general tendonitis, which
Tenosynovial Giant Cell Tumor (TGCT) is a rare, typically benign tumor that arises from the synovium—the thin layer of tissue lining joints, bursae, and tendon sheaths. It is characterized by proliferation of synovial-like cells, leading to mass formation and joint damage. TGCT most commonly affects the knee, ankle, hip, and fingers, and is divided into
Tendonitis, also known as tendinitis, refers to the inflammation or irritation of a tendon—the fibrous tissue that connects muscle to bone. This condition typically results from overuse or repetitive strain, leading to pain, swelling, and restricted movement in the affected area. Tendonitis can affect any tendon in the body, but it most commonly occurs in
Tear film insufficiency refers to an inadequate quantity or poor quality of tears needed to maintain a healthy and lubricated ocular surface. This condition is a core component of dry eye disease (DED), a prevalent and often chronic issue that can significantly impact visual comfort, clarity, and ocular health. Tear film insufficiency disrupts the delicate
Pertussis, commonly known as whooping cough, is a highly contagious respiratory disease caused by Bordetella pertussis. While it can affect individuals of any age, it is particularly dangerous for infants under two months who are too young to be vaccinated. Maternal immunization with the Tdap vaccine during pregnancy, especially in the third trimester, has proven
Tardive dyskinesia (TD) is a chronic, often irreversible neurological condition characterized by involuntary, repetitive movements. These movements typically affect the face, lips, tongue, trunk, and limbs. TD is most frequently associated with long-term use of dopamine receptor-blocking agents, particularly antipsychotic medications used to treat schizophrenia, bipolar disorder, and other psychiatric conditions. Causes and Risk Factors
Taenia infection, clinically referred to as taeniasis, is a parasitic disease caused by the ingestion of Taenia species, primarily Taenia solium (pork tapeworm) and Taenia saginata (beef tapeworm). Infections occur globally, with higher prevalence in regions where sanitation is poor and raw or undercooked meat consumption is common. While often asymptomatic, Taenia infections can lead
The T3 suppression test is a specialized diagnostic tool employed in the evaluation of thyroid gland functionality, particularly in distinguishing between autonomous thyroid activity and normal regulatory function. This test assesses the pituitary-thyroid axis by observing the thyroid’s response to exogenous triiodothyronine (T3) administration. Traditionally used in differentiating thyroid nodules or confirming subclinical hyperthyroidism, the
T-cell lymphoblastic lymphoma (T-LBL) is a rare, aggressive non-Hodgkin lymphoma characterized by the malignant proliferation of immature T-cell precursors. Closely related to T-cell acute lymphoblastic leukemia (T-ALL), T-LBL is distinguished by its predominant involvement of nodal and extranodal tissues, particularly the mediastinum, without significant bone marrow infiltration at the time of diagnosis. Representing approximately 2%
T-cell acute lymphoblastic leukemia (T-ALL) is a rare and aggressive subtype of acute lymphoblastic leukemia, primarily originating from immature T lymphocytes. Representing approximately 15% of pediatric and 25% of adult ALL cases, T-ALL progresses rapidly and demands immediate medical intervention. This hematologic malignancy often involves the bone marrow, blood, thymus, and, in advanced stages, other
