Is a tapeworm disease acquired from eating row or not well cooked food. Can be due to Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm), Diphyllobothrium lactum (fish tapeworm) and Hymenolepsis nana (faecal oral contamination from human and dogs) leading to chronic malnutrition (Taeniasis) or multi-organ dissemination and dysfunction (Cysticercosis)
These are clinical syndrome characterized by chronic, localized tendon pain exacerbated by mechanical loading. Caused mostly by tendon overuse and metabolic factors. Classified as Acute or Chronic.
It is an acute, often fatal disease caused by an exotoxin produced by the anaerobic bacterium Clostridium tetani. It is acquired through wounds contaminated with spores of the bacteria and in the case of neonates, through the umbilical stump, resulting in neonatal tetanus.
The B-Cell System
B lymphocytes produce antibodies in two forms; a membrane-bound form and a secreted form. Membrane-bound antibody forms the B-cell antigen receptor. Following antigen stimulation, B lymphocytes differentiate into plasma cells, which secrete antibodies exhibiting the same antigen specificity as the B-cell receptor. This system is characterized as humoral immunity, due to this release of receptors into the “humoral” system which constitutes vascular contents and mucous environments. The humoral system also contains non-specific defense mechanisms, including the complement system In chemical terms, B-cell receptors are globulins (Ig or immunoglobulins). These immunoglobulins comprise a number of classes and subclasses, as well as numerous different specificities, but share a common structure
Thyroid disorders are conditions that affect the thyroid gland. There are specific kinds of thyroid disorders that includes hypothyroidism, hyperthyroidism, goiter, thyroid nodules and thyroid cancer.
Thyroid Storm (Crisis)
Thyroid storm is one of the most life-threatening endocrine emergencies, resulting from exacerbation of manifestations of thyrotoxicosis.
Tick-Borne Relapsing Fever
A bacterial infection caused by Borrelia bacteria, transmitted to humans through the bite of infected "soft tick" that live within rodent burrows feeding on the rodent. Humans typically come into contact with soft ticks when they sleep in rodent-infested cabins.
Is a superficial fungal infection (dermatophytosis), on the scalp. It is quite common in children.
Tinea Corporis (Body Ringworm)
Tinea corporis is a superficial fungal infection (dermatophytosis), commonly on the arms and legs, but may occur on any part of the body.
Tinea Pedis (Athlete’s Foot)
It is a common fungal infection of the toes and is often the source of infection at other sites.
Toxic Epidermal Necrolysis (TEN)
It is a severe life-threatening disorder with generalized loss of epidermis and mucosa. HIV disease increases the risk of developing TEN.
It is a chronic conjunctivitis caused by infection with Chlamydia trachomatis (bacteria). It is one of the commonest causes of blindness worldwide. There is a chronic inflammation of the conjunctiva leading to scarring of the upper eyelid tarsal plate, entropion and in turn of eyelashes.
This is a condition whereby there is pyogenic infection of large muscle/muscles with extensive necrosis of the involved muscle. This condition occurs more commonly in the tropics, affecting immunocompromised individual than normal individual. The cause is uncertain since abscess multiple pockets explored early are sterile but later culture of the pus usually yields Staphylococcus aureus.
