Protein C and protein S deficiency presenting as Budd-Chiari syndrome.

Protein C and S are vitamin K-dependent natural anticoagulants. They play a major role in hemostasis by degrading the activated factor V and factor VIII. Deficiencies of protein C and protein S are associated with increased risk of thrombotic events.

Persistent hyperinsulinemic hypoglycemia of infancy due to homozygous KCNJ11 (T294M) mutation.

Hyperinsulinemic hypoglycemia is the most common cause of persistent hypoglycemia in infancy. While most of the cases are sporadic more than 100 mutations have been reported in the familial type. The authors report a case of familial hyperinsulinemic hypoglycemia with homozygous T294M mutation of the KCNJ11 gene, which responded to diazoxide therapy.

Hypohidrotic ectodermal dysplasia with atrophic rhinitis and nasal myiasis.

Hypohidrotic/anhidrotic ectodermal dysplasia is a rare inherited disorder characterized by hypohidrosis/anhidrosis, hypotrichosis, dysodontia and heat intolerance. Most common mode of transmission is X-linked recessive, showing complete expression in males, and only partial manifestations in the female carrier heterozygotes. Features like atrophic rhinitis, nasal and aural myiasis, syndactyly, cleft lip and/or palate, mental retardation and immunodeficiency are uncommonly seen in this syndrome.
