'Maqianzi' (the dried ripe seed of Strychnos nux-vomica L.) contains 1.0-1.4% each of strychnine and brucine. After processing to reduce its toxicity, 'maqianzi' was used as a herbal remedy for rheumatism, musculoskeletal injuries and limb paralysis. A 42-year old woman with neck pain was prescribed 15 g of 'maqianzi' to be taken in two doses at 7 hours apart, although the recommended dose was 0.3-0.6 g. She was apparently well after drinking the first of two bowls of 'maqianzi' decoction. One hour after she drank the second bowl of herbal decoction, she suddenly developed tonic contractions of all her limb muscles and carpopedal spasm lasting 5 min, difficulty in breathing, chest discomfort and perioral numbness. The second bowl of decoction probably became more concentrated because of evaporation of water during continued boiling and contained a larger amount of 'maqianzi'. On arrival in the hospital 1 hour later, she complained of muscle pain and tiredness. She was found to have hyperventilation and weakness of four limbs, with muscle power of grade 5(-)/5. All her symptoms gradually subsided over the next few hours. This case illustrated that 'maqianzi' can cause strychnine poisoning even after processing, especially when the recommended dose is greatly exceeded. In any patient with 'unexplained' muscle spasms or convulsions, strychnine poisoning should be included in the differential diagnosis and they should be asked about the use of herbal medicines.

Gitelman's syndrome is an autosomal recessive renal tubular disorder characterized by severe hypomagnesaemia, hypokalaemia, metabolic alkalosis and hypocalcaemia. It is caused by defective NaCl transport in the Distal Convoluted Tubule and presents in adolescence or adulthood, with a distinctly more benign course than Bartter's Syndrome. The dominant clinical features are muscle weakness, fatigue, carpopedal spasm, cramps and tetany. We report the case of a 26 year old male who presented with flaccid quadriparesis and carpopedal spasms, hypokalaemia, hypomagnesaemia, hypocalcaemia and severe urinary magnesium wasting. He was treated with potassium and magnesium supplementation and regained full function of all limbs.

Tetany is a disorder with a very heterogeneous clinical manifestation. It includes neuromuscular hyperactivity, decreased attention, fatigue, constant anxiety. Attacks of tetany range from mild symptoms, which includes circumoral and distal paresthesias, hyperventilation, accompanied by shortness of breath, palpitation, dizziness, nausea and carpopedal spasm, through more severe symptoms like generalized seizures, loss of consciousness, muscle crumps to life-threatening emergencies like laryngospasm or arrhythmias. Tetany can be a result of many electrolyte disturbances, like hypocalcaemia, hypomagnesemia, hypokalaemia, alkalosis and electrolyte disturbances following hyperventilation. These disorders may occur in many clinical situations including diet deficiencies, alcoholism, endocrine diseases, genetic disorders, iatrogenic causes like proton pump inhibitors therapy and many, many others. It happens that tetany is diagnosed too late and therefore insufficiently cured. For these reason it deserves closer attention.

Idiopathic hypoparathyroidism leads to hypocalcemia and hyperphosphatasemia and usually has a genetic aetiology. The variable but often subtle signs and symptoms usually lead to a misdiagnosis of hypoparathyroidism. Case records of 32 patients of idiopathic hypoparathyroidism admitted over a period of five years were analysed. There was a lag period of 5.94 years from the onset of symptoms to the diagnosis. Carpopedal spasm was the most common indication for admission to the hospital. Trivial symptoms such as fatigue (84%) and paresthesia (62.5%) were the most common reported symptoms. A sum of 46.5% of the patients were on antiepileptic drugs before the correct diagnosis of hypoparathyroidism was made. This observation emphasized that Calcium profile should be obtained in patients with history of paresthesia and seizure to avoid the long delay in diagnosis of hypoparathyroidism.
