Pectus carinatum is an overgrowth of costal cartilage, causing the sternum to protrude forward. It primarily occurs among four 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 child's pectus ...
Besides affecting height and limb proportions, people with Marfan syndrome may have abnormal lateral curvature of the spine scoliosis, thoracic lordosis, abnormal indentation (pectus excavatum) or protrusion (pectus carinatum) of the sternum, abnormal joint flexibility, a high-arched palate with crowded teeth and an overbite, flat feet, hammer ...
Additional factors may present in the form of winging of the scapula, scoliosis, breast bone prominence (pectus carinatum), breast bone depression (pectus excavatum). Muscle abnormalities may present as hypotonia (low muscle tone), which may lead to lordosis (increased hollow in the back) due to poor abdominal muscle tone.
Guizar-Vasquez-Sanchez-Manzano syndrome is an extremely rare genetic and congenital disorder that is characterized by facial dysmorphisms (more specifically, chubby cheeks, mild frontal bossing, a beaked nose with an accompanying low nasal bridge, malar hypoplasia, peculiar philtrums and upper lips), pectus carinatum, and joint hypermobility.
Other common features include a "marfanoid habitus" characterized by long, slender fingers (arachnodactyly), unusually long limbs, and a sunken chest (pectus excavatum) or protruding chest (pectus carinatum). [5] It can be caused by variations in the gene PLOD1, or rarely, in the FKBP14 gene. [39]
Pectus carinatum; Hypoplastic nipples; Craniosynostosis is a birth defect where the skull closes too soon, before the brain has finished developing. [7] This is a symptom often associated with the presence of SCARF syndrome. [5] Abdomen Diastasis recti; Umbilical hernia; Skeletal Abnormally-shaped vertebrae; Craniosynostosis; Genitourinary ...
Nonmuscular diseases of the upper thorax such as kyphosis, pectus carinatum and pectus excavatum. [6] Diseases restricting lower thoracic/abdominal volume (e.g. obesity, diaphragmatic hernia, or the presence of ascites). [6] Pleural thickening.
Loeys–Dietz syndrome (LDS) is an autosomal dominant genetic connective tissue disorder. It has features similar to Marfan syndrome and Ehlers–Danlos syndrome. [3] [4] [5] The disorder is marked by aneurysms in the aorta, often in children, and the aorta may also undergo sudden dissection in the weakened layers of the wall of the aorta.
