This case reports deals with a male patient, white, aged 51, bricklayer, tobacco smoker. At 43 years old a tubercular epididimite was surgically treated with orchiectomy. Recently, the reports marked weakness, weight loss, headache, vertigo, hypotension. On admittance to the hospital, hyperpigmentation was also present. Previous therapy (cortisone acetate 40 mg/die), was suspended, clinical investigations showed impaired adrenal and thyroidal functions; antimicrosomal antibodies were also present. Therefore therapy with cortisone acetate (25 mg x 2/die, 9-alpha-fluorohydrocortisone 0.1 mg/die and L-thyroxine 100 mcg/die) was instituted with marked improvement of the patient's conditions. This case reports highlights the importance of proceeding with complete investigations on the system, even when dealing with a tubercular Addison's disease.

A patient with Addison's disease, treated with conventional hydrocortisone replacement, developed deep hyperpigmentation, headache and vomiting. Plasma adrenocorticotropin (ACTH) level was extremely high, showing abnormal diurnal rhythm. Suppression of ACTH with glucocorticoids was attenuated and the responses to ovine corticotropin-releasing hormone (oCRF) and lysine vasopressin (LVP) were absent. Magnetic resonance imaging (MRI) suggested an enlargement of the pituitary gland, while immunohistological examination of pituitary fragments obtained by transsphenoidal surgery revealed corticotroph hyperplasia without microadenoma. Postoperatively, plasma ACTH returned to normal and adequately responded to oCRF and LVP. Over the year since surgery, the symptoms have gradually improved and the patient has resumed normal activities.

The authors report two cases of pseudotumor cerebri in patients taking lithium for treatment of bipolar disorder. Pseudotumor cerebri is a poorly understood syndrome characterized by chronic headaches, bilateral papilledema, and increased intracranial pressure without localized neurologic signs or symptoms, intracranial mass, or hydrocephalus. Ventriculography, computed tomography, and nuclear magnetic resonance imaging reveal normal or small ventricles. Multiple etiologies may include Vitamin A toxicity, obesity, head trauma, hypothyroidism or hyperthyroidism, prolonged steroid therapy or its withdrawal, Addison's disease, Cushing's disease, pituitary insufficiency, and lithium therapy. Patients treated with lithium whose antidiuretic hormone-cyclic adenosine monophosphate mechanism is disturbed are most likely to develop pseudotumor cerebri via disregulation of sodium balance, thyroid-stimulating hormone production, and glucose metabolism. The authors recommend careful medical monitoring to avoid iatrogenic effects of lithium, including pseudotumor cerebri.

A patient with Schmidt's syndrome and atypical symptoms of Addison's disease is presented. Autoimmune thyroiditis was diagnosed at the age of 12 years and then at 15 years; a diagnosis of migraine was made following 10 days of headache, visual field defects and dysarthria. One week later the patient was admitted to hospital in critical condition. Addison's disease was diagnosed and replacement therapy was introduced which brought about a rapid clinical improvement. Positive adrenal autoantibodies confirmed the diagnosis. We suggest that patients with organ-specific autoimmune disease undergo annual screening for adrenal activity, and in the event of abnormal results, adrenal autoantibody evaluation should be carried out, to avoid a life-threatening crisis caused by Addison's disease, which is often difficult to recognize due to atypical clinical presentation, as in the patient reported here.

Mutation in the orphan nuclear receptor DAX-1 gene causes X-linked adrenal hypoplasia congenita (AHC). Affected male children classically suffer a salt-losing crisis and adrenal insufficiency in their early infancy or, in some rare exceptions, with late-onset subtype. We report here a patient manifesting late-onset adrenal hypoplasia congenita caused by the premature truncation of the C-terminus of the DAX-1 molecule, which is essential for its function as a transcriptional repressor. A 12-year-old boy was referred to us after being afflicted with generalized skin pigmentation for about 3 years, fatigue and headache. Primary adrenal insufficiency was determined on the basis of a low plasma cortisol level (3.9 microg/dl) despite an extremely high ACTH level (1200 pg/ml). Replacement therapy with hydrocortisone and fludorocortisone acetate was initiated soon thereafter. Hypogonadotropic hypogonadism was confirmed at the age of 18 years, at which time sexual infantilism had become apparent. Direct sequencing of the peripheral lymphocyte-derived DNA revealed a novel 1033del13 mutation on the ligand-binding domain of the NR0B1 (DAX-1) gene, which generated a premature stop codon truncating the C-terminus. This mutation was considered de novo since we could not find it in his mother. This case demonstrates that even a truncated protein lacking the major functional domain of DAX-1 can present late-onset and latent adrenal failure.

Autoimmune polyendocrine syndrome type II (APS-II) is the most common immunoendocrinopathy syndrome. APS-II is defined by the development of two or more of the following entities: primary adrenal insufficiency (Addison's disease), Graves' disease, type 1A diabetes mellitus, autoimmune thyroiditis, primary hypogonadism, celiac disease, and myasthenia gravis. Other frequent clinical findings are vitiligo, alopecia, pernicious anemia and/or serositis. Primary adrenal insufficiency in these patients affects the adrenal cortex, which is destroyed by autoantibodies against 21-hydroxylase. Unlike other causes of adrenal insufficiency (infectious diseases, infiltrative diseases, bleeding, tumors), the adrenal medulla is not involved. Pheochromocytomas are tumors arising from the chromaffin cells of the sympathetic nervous system in the adrenal medulla. The clinical symptoms of these tumors vary from isolated hypertension or hypertension accompanied by paroxysmal episodes -including the classical triad of headache, palpitations and diaphoresis-to potentially serious manifestations such as acute pulmonary edema, arrhythmias and sudden death. Nevertheless, up to 40% of affected patients are asymptomatic. We present the case of a patient diagnosed with APS-II who developed a pheochromocytoma. In this patient, the adrenal gland cortex was atrophied and the tumor was attached to the adrenal medulla. This coexistence of endocrinopathies, with no etiologic connection, is a surprising finding, which has not previously been described in the current literature.

Idiopathic intracranial hypertension is a diagnosis of exclusion defined by elevated intracranial pressure without mass lesions or hydrocephalus. Causes of idiopathic intracranial hypertension include obesity, vitamin derangements, antibiotics, corticosteroids, and autoimmune disorders. Cushing's disease and Addison's disease have been associated with idiopathic intracranial hypertension. Secondary adrenal insufficiency following withdrawal of inhaled corticosteroids has been found to be a relatively common phenomenon. This case describes an 11-year-old boy who was previously on inhaled corticosteroids for severe asthma who presented with secondary adrenal insufficiency after withdrawal of steroids. The adrenal insufficiency presented as idiopathic intracranial hypertension. We described the hospital course and process of diagnosis for this child with secondary adrenal insufficiency following withdrawal of inhaled corticosteroids. The association between the discontinuation of this patient's corticosteroids and his onset of headache suggests secondary adrenal insufficiency as the most likely cause of his idiopathic intracranial hypertension. The gradual improvement in his symptoms after steroid replacement further supports this. Due to the significant prevalence of children using inhaled corticosteroids, it is important for clinicians to be aware of the potential for the withdrawal of these drugs to induce hypothalamic-pituitary-adrenal axis suppression.

Background: Mitochondrial diseases are caused by dysfunctions in mitochondrial metabolic pathways. MELAS syndrome is one of the most frequent mitochondrial disorders; it is characterized by encephalopathy, myopathy, lactic acidosis, and stroke-like episodes. Typically, it is associated with a point mutation with an adenine-to-guanine transition at position 3243 of the mitochondrial DNA (mtDNA; m.3243A>G) in the mitochondrially encoded tRNA leucine 1 (MT-TL1) gene. Other point mutations are possible and the association with polyglandular autoimmune syndrome type 2 has not yet been described. Case presentation: We present the case of a 25-year-old female patient with dysexecutive syndrome, muscular fatigue, and continuous headache. Half a year ago, she fought an infection-triggered Addison crisis. As the disease progressed, she had two epileptic seizures and stroke-like episodes with hemiparesis on the right side. Cerebral magnetic resonance imaging showed a substance defect of the parieto-occipital left side exceeding the vascular territories with a lactate peak. The lactate ischemia test was clearly positive, and a muscle biopsy showed single cytochrome c oxidase-negative muscle fibers. Genetic testing of blood mtDNA revealed a heteroplasmic base exchange mutation in the mitochondrially encoded NADH:ubiquinone oxidoreductase core subunit 4 (MT-ND4) gene (m.12015T>C; p.Leu419Pro; heteroplasmy level in blood 12%, in muscle tissue: 15%). The patient suffered from comorbid autoimmune polyglandular syndrome type 2 with Hashimoto's thyroiditis, Addison's disease, and autoimmune gastritis. In addition, we found increased anti-glutamic acid decarboxylase 65, anti-partial cell, anti-intrinsic factor, and anti-nuclear antibodies. Conclusion: We present an atypical case of MELAS syndrome with predominant symptoms of a dysexecutive syndrome, two stroke-like episodes, and fast-onset fatigue. The symptoms were associated with a not yet described base and aminoacid exchange mutation in the MT-ND4 gene (m.12015T>C to p.Leu419Pro). The resulting changed protein complex in our patient is part of the respiratory chain multicomplex I and might be the reason for the mitochondriopathy. However, different simulations for pathogenetic relevance are contradictory and rather speak for a benign variant. To our knowledge this case report is the first reporting MELAS syndrome with comorbid polyglandular autoimmune syndrome type 2. Screening for autoimmune alterations in those patients is important to prevent damage to end organs.

Background Autoimmune polyglandular syndrome type II (APS II) is defined as the combination of autoimmune adrenal insufficiency and autoimmune thyroid disease (AITD) and/or type I diabetes mellitus (T1DM) in the same patient. Case presentation A 15-year-old boy had a history of weight loss, nausea and vomiting, headache, restlessness, and tanned skin. He was diagnosed with Graves' disease. Two weeks after carbimazol therapy was commenced, he presented with adrenal crises (fever, arterial hypotension, hyponatremia, adrenocorticotropic hormone [ACTH] 1119.6 ng/mL [normal range <60] and low cortisol). He received hydrocortisone and fludrocortisone, and improved quickly. Thyroid-stimulating hormone (TSH) receptor autoantibodies as well as 21-hydroxylase antibodies were elevated. Conclusions Although the combination of Graves' and Addison's disease is extremely rare, especially in children, it is critical to make the diagnosis. Accelerated metabolic rate increased the risk for adrenal crises in our patient. This case contributes to the spectrum of APS II and its manifestation.
