Familial glucocorticoid deficiency is a rare multisystem disorder characterized by glucocorticoid deficiency with normal mineralocorticoid activity, achalasia of the cardia, and alacrima. Familial hypophosphatemic rickets is characterized by selective renal phosphate wasting with subsequent hypophosphatemia and an inappropriately low 1,25-dihydroxyvitamin D concentration for the degree of hypophosphatemia. A 6-year-old girl with both disorders is described. A biochemical relationship between familial glucocorticoid deficiency and familial hypophosphatemic rickets could not be defined; the influence of cortisol on her serum calcium level, phosphorus level, and rickets, as well as the natural history of these two entities, is described.

Allgrove syndrome (triple A syndrome) is a rare autosomal recessive disorder characterized by achalasia, alacrima, adrenal insufficiency, and--occasionally--autonomic instability. Disease causing mutations have been found in the AAAS gene on 12q13, but no strong phenotype-genotype correlation could be found. We present a 28 year-old woman with classical systemic features of triple A syndrome with prominent neurological dysfunctions/deficits, including distal muscular atrophy, progressive muscle weakness and wasting of both legs, sensibility dysfunction, hyperreflexia and autonomic dysfunction presented with excessive sweating. DNA sequencing of the AAAS gene revealed compound heterozygosity for previously reported mutations. A similar genotype was previously reported, but with a remarkably different phenotype.

Many cases have been published showing a co-existence of autoimmune thyroid diseases (AITDs) and other autoimmune diseases. About a quarter of patients with achalasia have a concurrent thyroid disease, most commonly associated with hypothyroidism. Although relatively rare, the association of achalasia and hyperthyroidism requires attention. The physiopathology of Grave's Disease (GD) involves B- and T-mediator lymphocytes, which have an affinity for known thyroid antigens: thyroglobulin, thyroid-peroxidase, and thyrotrophin receptor. Currently, however, the real physiopathogenesis of achalasia continues to be unknown. Some important findings are suggestive of an autoimmune mechanism: significant infiltration of the myoenteric plexus by monocytes, presence of the class II-Human Histocompatibility Complex DQwl antigen and antibodies to myoenteric neurons. The present case reports a patient who, despite testing negative for Chagas' disease, had achalasia, progressed to developing significant wasting and worsening of his quality of life, was later diagnosed with hyperthyroidism. After endoscopic esophageal dilatation and radioiodine ablation of the thyroid gland, there was great improvement in the patient clinical condition.
