Early Vitamin K Deficiency Bleeding in a Neonate Associated with Maternal Acute Fatty Liver of Pregnancy

Introduction Acute fatty liver of pregnancy (AFLP) is a rare but potentially fatal condition occurring in the third trimester or early postpartum period. It is characterized by microvesicular fatty infiltration of the liver. Clinically, the three most prominent derangements in women with AFLP are hepatic dysfunction, renal insufficiency, and impaired coagulation. AFLP is associated with an increased incidence of morbidity and mortality in neonates, though the exact cause for this remains unclear. Deficiency of vitamin K in patients with liver disease has been widely reported. Case Description We present a unique case of severe intracranial bleeding because of the early vitamin K deficiency in a neonate whose mother had AFLP along with accompanying renal insufficiency. Conclusion We suggest that monitoring infants born to mothers with AFLP, for vitamin K deficiency bleeding will help reduce morbidity and mortality in these infants.

The calcaneus: normal and abnormal

The calcaneus is the largest tarsal bone. Many congenital and acquired disorders affect the bone. Primary disorders arise in the calcaneus itself, whereas secondary disorders arising in the neighboring soft tissues extend into and affect the calcaneus indirectly. Among the primary lesions, congenital, traumatic, infectious, hematologic, neoplastic, and other miscellaneous disorders constitute the majority, whereas various arthritides and soft-tissue neoplasms that arise adjacent to the bone constitute the important secondary calcaneal disorders. Radiographic features of many disorders of the calcaneus are disease-specific and thus diagnostic. This article describes a wide spectrum of calcaneal disorders and illustrates their salient radiographic features. This knowledge should facilitate radiographic diagnosis of various calcaneal disorders encountered in clinical practice.
