As the child grows older, bodybuilding techniques may be useful for balancing visual impact.A less common variant of pectus carinatum is pectus arcuatum (also called type 2 pectus excavatum, chondromanubrial malformation or Currarino–Silverman syndrome or pouter pigeon malformation), which produces a manubrial and upper sternal protrusion, particularly also at the sternal angle. Pectus arcuatum is often confused with a combination of pectus carinatum and pectus excavatum, but in pectus arcuatum the visual appearance is characterized by a protrusion of the costal cartilages and there is no depression of the sternum. Causes
Pectus carinatum is an overgrowth of costal cartilage causing the sternum to protrude forward. It primarily occurs among four different patient groups, and males are more frequently affected than females. Most commonly, pectus carinatum develops in 11-to-14-year-old pubertal males undergoing a growth spurt. Some parents report that their childs pectus carinatum seemingly popped up overnight. Second most common is the presence of pectus carinatum at or shortly after birth. The condition may be evident in newborns as a rounded anterior chest wall. As the child reaches age 2 or 3 years of age, the outward sternal protrusion becomes more pronounced. Pectus carinatum can also be caused by vitamin D deficiency in children (Rickets) due to deposition of unmineralized osteoid. Least common is a pectus carinatum malformation following open-heart surgery or in children with poorly controlled bronchial asthma. Pectus carinatum is generally a solitary, non-syndromic abnormality.
Tinea barbae is a fungal infection of the hair. Tinea barbae is due to a dermatophytic infection around the bearded area of men. Generally, the infection occurs as a follicular inflammation, or as a cutaneous granulomatous lesion, i.e. a chronic inflammatory reaction. It is one of the causes of folliculitis. It is most common among agricultural workers, as the transmission is more common from animal-to-human than human-to-human. The most common causes are Trichophyton mentagrophytes and T. verrucosum. Signs and symptoms
Main symptoms that occur when affected with tinea barbae is pimple or blister amongst affected area, swelling and redness around infected area, red and lumpy skin on infected area. Crusting around hairs in infected area will occur, hairs on infected area will also be effortless to pull out. Tinea barbae can be itchy or painful to touch but these symptoms do not always occur. Transmission
The transmission of tinea barbae to humans occurs through contact of an infected animal to the skin of a human. Infection can occasionally be transmitted through contact of infected animal hair on human skin. Tinea barbae is very rarely transmitted through human to human contact but is not completely impossible. Diagnosis
Diagnosis of tinea barbae will firstly include questions being asked from doctors about interactions with farm animals and lifestyle experiences. Doctor will then gain knowledge on possible disease by microscopy, this is viewing the skin under a microscope to get an enlarge view of infected area. Skin scraping and removal of hairs on infected area will occur for medical examination.
