In healthy individuals, resistance training and heavy manual labour creates muscle hypertrophy through signalling from mechanical stimulation (mechanotransduction) and from sensing available energy reserves (such as AMP through AMP-activated protein kinase); however, in the absence of a sports or vocational explanation for muscle hypertrophy ...
The masseter muscle can become enlarged in patients who habitually clench or grind (with bruxism) their teeth and even in those who constantly chew gum. This masseteric hypertrophy is asymptomatic and soft; it is usually bilateral but can be unilateral. Even if the hypertrophy is bilateral, asymmetry of the face may still occur due to unequal ...
The signs and symptoms of a submasseteric abscess may include marked trismus (i.e. difficulty opening the mouth, since the masseter elevates the mandible and it becomes restricted) and swelling in the region of the masseter muscle. [1] The treatment of a submasseteric space infection is usually by surgical incision and drainage, and the ...
Clitoromegaly is a rare condition and can be either present by birth or acquired later in life. If present at birth, congenital adrenal hyperplasia can be one of the causes, since in this condition the adrenal gland of the female fetus produces additional androgens and the newborn baby has ambiguous genitalia which are not clearly male or female.
It can broadly be classified as either right atrial hypertrophy (RAH), overgrowth, or dilation, like an expanding balloon. Common causes include pulmonary hypertension , which can be the primary defect leading to RAE, or pulmonary hypertension secondary to tricuspid stenosis ; pulmonary stenosis or Tetralogy of Fallot i.e. congenital diseases ...
Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. [1] Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent. [ 2 ]
It might be more accurate to say that metabolic myopathies described as adult-onset, it isn't necessarily that they didn't develop in infancy (they are inborn—from birth—errors of metabolism) but that they didn't display severe enough symptoms to warrant the attention of medical professionals until their adult years (severe symptoms such as ...
