Neonatal hypocalcemia is an abnormal clinical and laboratory hypocalcemia condition that is frequently observed in infants. It is commonly presented within the first 72 hours of a newborns life.Healthy term infants go through a physiological nadir of serum calcium levels at 7.5 - 8.5 mg/dL by day 2 of life. Hypocalcemia is a low blood calcium level. A total serum calcium of less than 8 mg/dL (2mmol/L) or ionized calcium less than 1.2 mmol/L in term neonates is defined as hypocalcemia. In preterm infants, it is defined as less than 7mg/dL (1.75 mmol/L) total serum calcium or less than 4mg/dL (1 mmol/L) ionized calcium. Both early onset hypocalcemia (presents within 72h of birth) and late onset hypocalcemia (presents in 3-7 days after birth) require calcium supplementation treatment. Infants with intrauterine growth retardation, perinatal asphyxia, preterm, and diabetic mothers are most likely to develop neonatal hypocalcemia. It is not understood why premature infants have hypocalcemia, but a proposed idea is that a large increase of calcitonin may lead to hypocalcemia. Another hypothesis includes impaired secretion of PTH or Parathyroid hormone. Cause
Risk factors of early neonatal hypocalcemia

There is a suggestion that treatment of factors that modulate pain sensitivity such as mood disorders, anxiety and fatigue, may be important in the treatment of TMD, which often tends to attempt to address the pain directly.Cognitive Behavioral Therapy (CBT) has been used in TMD and has been shown to be efficacious by meta analyses.Hypnosis is suggested by some to be appropriate for TMD. Studies have suggested that it may even be more beneficial than occlusal splint therapy, and has comparable effects to relaxation techniques.Relaxation techniques include progressive muscle relaxation, yoga, and meditation. It has been suggested that TMD involves increased sensitivity to external stimuli leading to an increased sympathetic ("fight or flight") response with cardiovascular and respiratory alterations. Relaxation techniques cause reduced sympathetic activity, including muscle relaxation and reducing sensitivity to external stimuli, and provoke a general sense of well-being and reduced anxiety. Devices
Occlusal splints (also termed bite plates or intra-oral appliances) are often used by dentists to treat TMD. They are usually made of acrylic and can be hard or soft. They can be designed to fit onto the upper teeth or the lower teeth. They may cover all the teeth in one arch (full coverage splint) or only some (partial coverage splint). Splints are also termed according to their intended mechanism, such as the anterior positioning splint or the stabilization splint. Although occlusal splints are generally considered a reversible treatment, sometimes partial coverage splints lead to pathologic tooth migration (changes in the position of teeth).
