Patients with either phosphorylase or phosphorylase kinase deficiencies present in early childhood with hepatomegaly and growth retardation. Hypoglycemia and hyperlipidemia are variable and, if present, usually mild. [ommbid.mhmedical.com]

Otherwise, fasting hypoglycaemia in adulthood may be a presenting sign of an IEM, although they are rare. [ojrd.biomedcentral.com]

This is presumably due to different isoenzymes being present in different tissues. Mild degrees of galactose kinase deficiency present solely with cataracts in childhood. This enzyme also can be assayed in RBCs. [emedicine.medscape.com]

  • Amyloidosis

    Symptoms of amyloidosis depend on the organs it affects. The wide range of symptoms often makes amyloidosis difficult to diagnose. [encyclopedia.com]

    Diagnosis [ edit ] Several different problems may lead to the diagnosis, usually by two years of age: seizures or other manifestations of severe fasting hypoglycemia hepatomegaly with abdominal protuberance hyperventilation and apparent respiratory distress [en.wikipedia.org]

    Many pediatric cases present with impaired consciousness, repeated seizures, severe anemia, respiratory distress, or shock. [ahcmedia.com]

  • Muscle Weakness

    Increased acidity in the blood can lead to vomiting, abdominal pain, extreme tiredness (fatigue), muscle weakness, and difficulty breathing. In some cases, episodes of lactic acidosis are triggered by an illness or periods without food (fasting). [icdlist.com]

    It presents with hypoglycemia, failure to thrive, metabolic acidosis, muscle weakness, and hepatomegaly. [icd10data.com]

    In patients with disease also involving muscle (type IIIa), muscle weakness, though minimal during childhood, can become predominant in adults; these patients show signs of neuromuscular involvement, with slowly progressive weakness and distal muscle [ommbid.mhmedical.com]

    Other disorders : PEP carboxykinase deficiency is very rare; begins in neonatal period and involves FTT, microcephaly, developmental delay, seizures, hepatomegaly, renal tubular acidosis, cardiomyopathy and muscle weakness (van den Berghe, 1996). [pedclerk.bsd.uchicago.edu]

  • Arthritis

    As a consequence, glucocorticoids are widely used as drugs to treat inflammatory conditions such as arthritis or dermatitis, and as adjunction therapy for conditions such as autoimmune diseases. [vivo.colostate.edu]

    Fortunately, the urine discoloration is not detrimental to people with this IEM; however, alkaptonurics do tend to develop arthritis later in life. PKU is a serious IEM caused by a liver enzyme deficiency. [encyclopedia.com]

    The buildup of uric acid in the joints and tissues causes arthritis and inflammation. gp100 A tumor-specific antigen used in the development of cancer vaccines. [cancer.gov]

  • Psychomotor Retardation

    retardation-progressive brain atrophy-basal ganglia disease syndrome Intermediate maple syrup urine disease Intermediate severe Salla disease Intermittent maple syrup urine disease Isobutyryl-CoA dehydrogenase deficiency Isolated ATP synthase deficiency [se-atlas.de]

  • Muscle Tone Abnormalities

    In the most severe form, pyruvate carboxylase deficiency results in progressive neurologic symptoms, starting in the neonatal or early infantile period, including developmental delay, poor muscle tone, abnormal eye movements, and seizures. [emedicine.medscape.com]

  • Motor Disturbances

    Signs and symptoms appear early in life and include failure to thrive, mental and growth retardation, motor disturbances, seizures, and lactic acidosis. [icd10data.com]

Workup The initial workup readily identifies lactic acidosis. Once the more common acquired causes of lactic acidosis have been excluded, order appropriate tests to diagnose one of the less common inborn errors of metabolism. [emedicine.medscape.com]

The diagnosis workup is summarized in Figure 2. [ojrd.biomedcentral.com]

  • Polyps

    Blood in the stool may be a sign of colorectal cancer or other problems, such as polyps, ulcers, or hemorrhoids. [cancer.gov]

Prognosis and treatment of glycogen storage diseases vary by type, but treatment typically includes dietary supplementation with cornstarch to provide a sustained source of glucose for the hepatic forms of GSD and exercise avoidance for the muscle forms [msdmanuals.com]

TREATMENT: Treatment options vary and are dependent upon the underlying cause of the hypercortisolism. Therefore differentiation of the cause is essential for effective treatment. [wikilectures.eu]

This concept has been used in PCD. [ 8 ] Prognosis Despite all therapeutic interventions, the prognosis remains poor, with the majority of affected children dying before the age of six months. [patient.info]

Prognosis is good; adult patients have normal stature and minimal hepatomegaly. [ommbid.mhmedical.com]

We attempt to define MetS mechanistically to determine its specific etiologies and to identify targets for therapy. [pediatrics.aappublications.org]

There are many etiologies, but the syndrome is generally classified into two categories- Adrenocorticotropic hormone (ACTH) dependent or ACTH independent. A third pseudo-Cushing’s syndrome is also discussed. [wikilectures.eu]
