@entity3747 ( @entity3747 ) is common in the neonatal period. Its cause falls into one of two clinical categories, early @entity3747 occurs in first 24-48 hours of life; late @entity3747 is observed at the end of the first week of life. @entity3747 due to @entity261 , either permanent or transient, is rare. They both present with @entity3747 , low levels of intact parathyroid hormones, and @entity2265 . In this paper we report on four cases of @entity3747 due to @entity261 . They are all full-term @entity1 with normal birth weights, carried by nondiabetic mothers. The age of onset was 6 days old to 17 days old, there were three male and one female. @entity410 was the major symptom except for case 2, who had a high pitch crying, @entity146 and opisthotonus. Laboratory data revealed @entity460 : 4.7 to 6.3 mg/dl, @entity3151 : 6.8 to 9.2 mg/dl, and @entity1760 : 1.2 to 2.8 mg/dl. The intact parathyroid hormone levels were abnormally low in two cases (<13 pg/ml and 5.7 pg/ml), yet only subnormal in the other two (25.2 pg/ml and 22.2 pg/ml). Further studies on these four babies showed no evidence of @entity6007 . Interestingly, two @entity1 ' mothers were found to have hyperparathvroidism. In conclusion, in case of @entity3747 , measurements of @entity460 , @entity3151 , and intact- @entity461 in neonates are required to recognize @entity261 . Pediatricians should always check maternal parathyroid status to rule out maternal @entity2742 .
