Congenital malformations, deformities, and chromosomal abnormalities (Q00-Q99).
- Pseudohypoparathyroidism (synonym: Martin-Albright syndrome) – genetic disorder with autosomal dominant inheritance; symptoms of hypoparathyroidism (hypothyroidism) without a deficiency of parathyroid hormone (PTH) in the blood: four types are distinguished according to appearance:
- Type Ia: concomitant Albright osteodystrophy: brachymetacarpy (shortening of single or multiple metacarpal bones) and tarsy (shortening of single or multiple metatarsal bones), round face, short stature
- Type Ib; as in type 1a, there is renal PTH resistance, resistance to other hormones, especially thyrotropin are also possible; there is no Albright osteodystrophy
- Type Ic: identical to type 1a, except that receptor-independent cAMP production is preserved in vitro.
- Type II: probably several subtypes, Albright osteodystrophy is not present.
Respiratory system (J00-J99)
- Bronchial asthma
Endocrine, nutritional and metabolic diseases (E00-E90).
- Parathreogenic tetany – after parathyroidectomy (parathyroidectomy), in idiopathic hypoparathyroidism (parathyroid hypofunction).
- Recalcification tetany – after parathyroidectomy (parathyroidectomy).
- Enterogenic/primary calcium deficiency tetany – in the presence of malabsorption or malnutrition.
- Hyperventilation tetany – in respiratory (breathing-related) alkalosis (disturbance of acid-base balance).
- Magnesium deficiency tetany – due to hypomagnesemia (magnesium deficiency).
- Gastric tetany (chloriprive tetany) – due to hypochloremia (decreases in chloride in the blood fluid) after vomiting.
Infectious and parasitic diseases (A00-B99).
- For infectious diseases, unspecified
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Celiac disease (gluten-induced enteropathy) – chronic disease of the mucosa of the small intestine (small intestinal mucosa) due to hypersensitivity to the cereal protein gluten.
Psyche – nervous system (F00-F99; G00-G99).
- Epilepsy
- Idiopathic tetany – in neurasthenics, psychopathies.
- Meningoencephalitis – combined inflammation of the brain (encephalitis) and meninges (meningitis).
- Central (brain-related) tetany – in hypothalamic lesions (injuries in the area of the hypothalamus/section of the diencephalon in the area of the optic nerve junction).
Pregnancy, childbirth, and puerperium (O00-O99).
- Gravidity tetany – due to hyperemesis (increased vomiting during pregnancy) or gestosis (umbrella term for a number of conditions unique to pregnancy).
Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99).
Injuries, poisonings, and other sequelae of external causes (S00-T98).
- Toxic (based on poison effect) tetany – due to oxalates, fluorides, citrate.
- In drug poisoning – epinephrine, guanidine, caffeine, morphine.
- Craniocerebral trauma (TBI) (craniocerebral injury), unspecified.
