We report a patient who presented with anxiety, hyperventilation, perioral paresthesia, and tingling in the fingers associated with hypomagnesemia, hypocalcemia, and hypokalemia. We discuss the possible mechanistic basis for sequence of events that may have led to this presentation.

Review
Magnesium deficit has been associated with many sub-clinical and clinical conditions in humans and animals. The incidence of hypomagnesaemia is high in lactating cows grazing spring pastures, occasionally resulting in the often fatal condition known as grass tetany. While plasma magnesium concentrations can be used to assess magnesium status in the live animal, post-mortem diagnosis of clinical grass tetany is difficult. Recent studies have investigated the potential of eye fluid magnesium concentration as a post-mortem marker of hypomagnesaemic tetany. In tetany induction studies carried out in adult ewes and lactating cows significant relationships were found to exist between the concentrations of magnesium in either cerebrospinal fluid or plasma and either aqueous or vitreous humour. In freshly dead animals aqueous humour magnesium concentrations of < 0.33 mmol/L in adult sheep and < 0.25 mmol/L in adult cattle were associated with severe hypomagnesaemia and tetany. However, aqueous humour was found to be unstable post-mortem. Vitreous humour was considerably more stable and a vitreous humour magnesium concentration in adult sheep of < 0.65 mmol/L for up to 24 hours post-mortem or < 0.55 mmol/L in adult cows for up to 48 hours was associated with severe hypomagnesaemia and tetany. Provided clear-fluid samples are taken from appropriate animals and processed correctly in the laboratory, the concentration of magnesium in vitreous humour is a useful and practical marker in the post-mortem diagnosis of hypomagnesaemic tetany in ruminants.

Review
Magnesium (Mg) is a mineral that plays an essential role as cofactor of more than 300 enzymes. Mg in farm animals' and human nutrition is recommended to avoid Mg deficiency, ensure adequate growth and health maintenance. Mg supplementation above the estimated minimum requirements is the best practice to improve farm animals' performances (fertility and yield) and food products' quality, since the performance of farm animals has grown in recent decades. Mg supplementation in pigs increases meat quality and sows' fertility; in poultry, it helps to avoid deficiency-related health conditions and to improve meat quality and egg production by laying hens; in dairy cows, it serves to avoid grass tetany and milk fever, two conditions related to hypomagnesaemia, and to support their growth. Thus, Mg supplementation increases food products' quality and prevents Mg deficiency in farm animals, ensuring an adequate Mg content in animal-source food. These latter are excellent Mg sources in human diets. Sub-optimal Mg intake by humans has several implications in bone development, muscle function, and health maintenance. This review summarizes the main knowledge about Mg in farm animals and in human nutrition.

Review
In the past century, thyroid surgery has benefited from physiological and technical revolutions. In the early 1900s, the most important aspect of thyroidectomy was the volume resected, without knowledge of exactly what was removed and if there were important structures around the thyroid gland. The main indications were respiratory problems for tracheal compression and the death rate was greater than 36% due to bleeding, infections, unrecognised bilateral recurrent laryngeal nerve lesions and unrecognised severe hypocalcaemia leading to tetany. At some point this surgery was, therefore, banned in some countries such as France and the United States. Today, thyroid surgery is a common surgery: about 45,000 thyroidectomies are performed per year in France, 60,000 in Germany and 4,000 in Switzerland. Thyroid surgery has become very safe with a mortality of almost 0% and a very low complication rate. In our centre, the number of thyroidectomies has more than tripled in the last decade. There are many indications leading to thyroid surgery, but the three main indications covering 90% of the interventions are cancer (or suspected cancer), hyperthyroidism and size / volume / intrathoracic goitres. In this paper, we highlight some historical points, describe important knowledge and technical improvements made during the last century and give our opinion on expected evolution in this field for the near future.
