112 Possible Causes for Chvostek Sign, Hypomagnesemia

  • Hypoparathyroidism

    The following are signs of hypocalcemia: Chvostek's sign (watch video) is the twitching of the facial muscles in response to tapping over the area of the facial nerve.[] Blood laboratory study results indicated serum hypocalcemia, hypomagnesemia, and hyperphosphatemia associated with a low parathyroid hormone level.[] […] awareness among physicians worldwide of this often unknown association, as life-threatening cardiac and neuromuscular complications can arise with unrecognized hypocalcemia and hypomagnesemia[]

  • Bartter's Disease

    Hypotension - may be symptomatic or asymptomatic based on volume status Tetany - positive Chvostek's and Trouseau's signs may be present in the setting of hypomagnesemia and[] In addition, some affected patients may have neuromuscular irritability as manifested by a positive Chvostek /or Trousseau sign or frank tetany due to alkalosis and hypomagnesemia[] […] type of genetic inheritance, manifested hypokalemia, metabolic alkalosis, hyperreninemia, hyperplasia juxtaglomerular apparatus (JGA), hyperaldosteronism, in some patients, hypomagnesemia[]

  • Hypomagnesemia

    signs.[] Hypomagnesemia was defined by serum magnesium concentration 0.74mmol/L.[] Chvostek sign is an involuntary twitching of the facial muscles elicited by a light tapping of the facial nerve just anterior to the exterior auditory meatus.[]

  • Hypocalcemia

    His examination demonstrated a slight resting tremor, normal strength, and negative Chvostek sign.[] General incidence of hypomagnesemia was 23.36%.[] sign: Twitching of the ipsilateral facial musculature (perioral, nasal, and eye muscles) by tapping over cranial nerve VII at the ear Chvostek's sign is neither sensitive[]

  • Gitelman Syndrome

    Chvostek's and Trousseau's signs were positive. Her clinical and neurological examinations revealed Grade 3 quadriparesis without sensory loss.[] Following her admission, intravenous potassium and magnesium supplementation was commenced to counter the observed hypokalemia and hypomagnesemia.[] Laboratory tests showed hypokalemia, metabolic alkalosis, hypocalciuria, and hypomagnesemia related to genetically proven GS.[]

  • Magnesium Deficiency

    Chvostek’s Sign and Trousseau’s Sign are both clinical tests for involuntary muscle movements, and both may indicate either calcium or magnesium deficiency, or both.[] A fourth of the patients who are diagnosed with diabetes have a concurrent hypomagnesemia.[] Among 111 patients with a positive EMG or Chvostek's sign, the frequency of MVP on M-mode echocardiography was 36%.[]

  • EAST Syndrome

    The possibility of calcium metabolism disorder was considered and corroborated by the presence of positive Chvostek's sign, a latent sign of tetany.[] […] localizes to the basolateral membrane of the renal distal convoluted tubule, and its loss of function mimics renal features of Gitelman syndrome, with hypokalemic alkalosis, hypomagnesemia[] Individuals also demonstrated significant hypomagnesemia and hypocalciuria.[]

  • Conn Syndrome

    May also be a metabolic alkalosis, hypomagnesemia and mild hypernatraemia.[]

  • Autosomal Dominant Hypocalcemia Type 1

    The physical findings which classically demonstrate increased neuromuscular irritability due to hypocalcemia are Trousseau's sign and Chvostek's sign.[] Hypomagnesemia Magnesium is essential for PTH release.[] General physical examination revealed positive Chvostek and Trousseau signs [Figure 1] . She was oriented to time, place, and person with no focal neurological deficit.[]

  • Hypokalemia

    sign ipsilateral facial muscle contraction caused by tapping the facial nerve Trousseau sign carpopedal spasms by inflating the sphygmomanometer above systolic blood pressure[] Hypophosphatemia, hypokalemia, and hypomagnesemia were frequent in hospitalized pediatric patients before and during the first 4 days of PN infusion.[] Hypomagnesemia is common in GS, but some types of BS can also present with such a phenotype.[]
