It is very thin over the upper part of the pectoralis major, but thicker in the interval between it and the latissimus dorsi, where it closes in the axillary space and forms the axillary fascia; it divides at the lateral margin of the latissimus dorsi into two layers, one of which passes in front of, and the other behind it; these proceed as far as the spinous processes of the thoracic vertebrae, to which they are attached. As the fascia leaves the lower edge of the pectoralis major to cross the floor of the axilla it sends a layer upward under cover of the muscle; this lamina splits to envelop the pectoralis minor, at the upper edge of which it is continuous with the coracoclavicular fascia. The hollow of the armpit, seen when the arm is abducted, is produced mainly by the traction of this fascia on the axillary floor, and hence the lamina is sometimes named the suspensory ligament of the axilla. At the lower part of the thoracic region the deep fascia is well-developed, and is continuous with the fibrous sheaths of the rectus abdominis. The clavipectoral fascia lies below the clavicular head of the pectoralis major. It fills in the space between the clavicle and the pectoralis minor. Between the 1st rib and the coracoid process of the scapula, the fascia is thickened to form the costocoracoid ligament. #pectoralsascia #clavipectoralfascia #pectoralregion #usmle #neetpg #mbbsanatomy #anatomy #upperlimbanatomy #usmlestep1 #bhanuprakash #medvizz #usmlevideos #usmlestep1videos

📌𝐅𝐨𝐥𝐥𝐨𝐰 𝐨𝐧 𝐈𝐧𝐬𝐭𝐚𝐠𝐫𝐚𝐦 :- https://www.instagram.com/drgbhanuprakash Common Variable Immunodeficiency (CVID) ------------------------------------------------------------------------ Common variable immunodeficiency (CVID) is a primary immune deficiency disease characterized by low levels of protective antibodies and an increased risk of infections. Although the disease usually is diagnosed in adults, it also can occur in children. CVID also is known as hypogammaglobulinemia, adult-onset agammaglobulinemia, late-onset hypogammaglobulinemia, and acquired agammaglobulinemia. NIAID supports research to determine genetic causes of CVID that may lead to therapeutic approaches to address the disease. Researchers also are exploring how antibody-based drugs may lessen the severity of the condition. Causes ------------- CVID is caused by a variety of different genetic abnormalities that result in a defect in the capability of immune cells to produce normal amounts of all types of antibodies. Only a few of these defects have been identified, and the cause of most cases of CVID is unknown. Many people with CVID carry a DNA variation called a polymorphism in a gene known as TACI. However, while this genetic abnormality confers increased risk of developing CVID, it alone is not capable of causing CVID. CVID is also linked to IgA deficiency, a related condition in which only the level of the antibody immunoglobulin A (IgA) is low, while levels of other antibody types are usually normal or near normal. IgA deficiency typically occurs alone, but in some cases it may precede the development of CVID or occur in family members of CVID patients. Symptoms & Diagnosis -------------------------------------- People with CVID may experience frequent bacterial and viral infections of the upper airway, sinuses, and lungs. Acute lung infections can cause pneumonia, and long-term lung infections may cause a chronic form of bronchitis known as bronchiectasis, which is characterized by thickened airway walls colonized by bacteria. People with CVID also may have diarrhea, problems absorbing food nutrients, reduced liver function, and impaired blood flow to the liver. Autoimmune problems that cause reduced levels of blood cells or platelets also may occur. People with CVID may develop an enlarged spleen and swollen glands or lymph nodes, as well as painful swollen joints in the knee, ankle, elbow, or wrist. In addition, people with CVID may have an increased risk of developing some cancers. Doctors can diagnose CVID by weighing factors including infection history, digestive symptoms, lab tests showing very low immunoglobulin levels, and low antibody responses to immunization. Treatment ---------------- CVID is treated with intravenous immunoglobulin infusions or subcutaneous (under the skin) immunoglobulin injection to partially restore immunoglobulin levels. The immunoglobulin given by either method provides antibodies from the blood of healthy donors. The frequent bacterial infections experienced by people with CVID are treated with antibiotics. Other problems caused by CVID may require additional, tailored treatments. #commonvariableimmunodeficiency #cvid #immunology #usmle #usmlestep1 #nationalexittest #mbbs #medicalanimations #medvizz #usmlestep1videos #cvid

It most commonly manifests with early onset, insulin-dependent diabetes mellitus; severe watery diarrhea, often with accompanying failure to thrive; and dermatitis. Other clinical features are more variable in their expression. Most affected children die within the first 2 years of life. IPEX syndrome is an X-linked recessive disorder with exclusive expression in males. The identification of mutations in the forkhead box protein 3 (FOXP3) gene associated with IPEX syndrome and a murine model has generated a considerable amount of interest and research. This has also extended into the therapeutic spectrum, with new immunosuppressive regimens and use of hematopoietic stem cell transplantation (HSCT). #ipexsyndrome #usmle #usmlestep1 #medvizz #fmge #usmlepreparation #medicalstudents #nationalexitexam #usmleprep #drgbhanuprakash #neetpg2023 #mbbslectures #usmleprep
