1/44. Periventricular brain heterotopias in a child with adrenocortical insufficiency, achalasia, alacrima, and neurologic abnormalities (Allgrove syndrome).

We describe a previously unreported finding of periventricular heterotopias in a brain magnetic resonance imaging (MRI) study, in a girl with adrenocortical insufficiency, alacrima, achalasia, and neurologic deterioration (Allgrove syndrome). This finding could indicate that the underlying mechanism in this syndrome can be traced to the first half of fetal life and also might cause abnormal neuronal migration. This disorder recently has been linked to chromosome 12q13. There could be several explanations for the clinical heterogeneity in this syndrome: a contiguous gene syndrome involving multiple genes, including one whose deletion causes heterotopias, or a deficiency of a gene for a neurotrophic factor active during pre- and postnatal life and responsible for both migration and survival of neurons could be the cause. The identification of the responsible gene(s) will lead to further understanding of this multisystem disorder.

2/44. Adrenal suppression secondary to inhaled fluticasone propionate.

BACKGROUND: Inhaled glucocorticoids are the medical treatment of choice in many of patients with asthma. Fluticasone propionate is an inhaled glucocorticoid with little systemic bioavailability via the oral route and infrequent association with systemic adverse effects at the recommended dosage. OBJECTIVE: To report a case of adrenal suppression and exogenous glucocorticoid excess from inhaled fluticasone propionate. methods: A 9-year-old girl with a previous history of episodic asthma was placed on 550 microg of fluticasone propionate daily for severe labile asthma diagnosed by history and methacholine challenge. The patient returned 6 months later with complaints of increased appetite, nausea, and feeling "hot and flushed." On physical exam she had stigmata of Cushing's syndrome. The patient subsequently developed orthostatic hypotension and moderate dehydration following a viral illness. After a long taper of fluticasone propionate the patient' s adrenal function returned to normal and she had no acute or chronic exacerbations of her asthma. RESULTS: Her 8 AM cortisol was undetectable with an ACTH of 21 pg/mL. The serum prolactin, TSH, free thyroxine, insulin-like growth factor i, and renin activity were all normal. An MRI study of her head was also normal. Repeat methacholine challenges while receiving a much smaller dose fluticasone propionate showed a significant decrease in airway reactivity. CONCLUSION: Adrenal suppression can occur from inhaled fluticasone propionate at a dosage less than has been previously reported.

3/44. Clinical and novel molecular findings in a 6.8-year-old Turkish boy with triple A syndrome.

BACKGROUND: The triple A syndrome is characterized by the main features adrenal insufficiency, achalasia and alacrima. Other organ systems can be involved in a variable manner. PATIENT: We report clinical and novel molecular findings in a 6.8-year-old Kurdish boy, who presented with relapsing vomiting and failure to thrive. He was diagnosed as having achalasia and primary adrenocortical hypofunction. history and clinical examination showed that the boy was unable to produce tears. In addition, a large number of associated neurological and dermatological features was present in this patient. Thus, the clinical diagnosis of triple A syndrome was made. RESULTS: Initial molecular marker analysis supported linkage to the triple A critical region on chromosome 12q13. Further, a homozygous G -->A transition in exon 9 of the newly identified AAAS gene, resulting in a stop codon (W295X) and predicting a truncated protein with loss of function, confirmed the diagnosis. This new mutation was also detected in another family of Kurdish origin. In turned out that both families were related.

4/44. Cushing's syndrome caused by topical steroid therapy for psoriasis.

A 72-year-old woman developed manifestations of Cushing's syndrome after long-term topical steroid therapy for psoriasis. Shortly after tapering the dose of topical steroids she developed signs of adrenal insufficiency (provoked by a urinary tract infection) requiring intravenous administration of a stress dose of hydrocortisone. There have only been a few reports of systemic side effects of topically applied corticosteroids in adults. Considering their serious consequences physicians should be alert to signs of Cushing's syndrome in patients on long-term topical steroid therapy. Furthermore, clobetasol propionate ointment doses exceeding 50 g a week should not be prescribed and use of occlusive dressings should be avoided.

5/44. Adrenal functions in children with adrenoleukodystrophy.

BACKGROUND: adrenoleukodystrophy refers to an inherited disorder that mainly affects the adrenal gland, and the nervous system. The most common type is X-linked adrenoleukodystrophy (XALD). The main presenting symptoms are behavioral changes. However, endocrinological manifestations are also important and need to be clarified especially adrenal insufficiency which is a lifethreatening condition that can be prevented. OBJECTIVE: To review the endocrinological and the adrenal functions in X-linked ALD. SUBJECTS AND METHOD: The medical records of four patients diagnosed with ALD at the endocrinology and Metabolic Unit, Department of pediatrics, King Chulalongkorn Memorial Hospital between 1998 and 2000 were reviewed. The diagnoses were confirmed by elevated very long chain fatty acid (VLCFA) levels and the typical changes seen on magnetic resonance imaging (MRI) of the brain. The adrenal functions in these patients were studied. RESULTS: All patients presented between 7-11 years of age with learning problems and behavioral changes, without symptoms of adrenal insufficiency such as nausea, vomiting and abdominal pain. However, the physical signs of adrenal insufficiency such as generalized hyperpigmentation particularly on the nipples, skin creases and genitalia were present. The laboratory investigations revealed normal blood sugar and serum electrolytes. The adrenal functions were revealed as follows. Basal ACTH levels were high in 2 cases (290, > 1,250 pg/mL). Basal cortisol level was low in 1 case. ACTH stimulation tests revealed subnormal responses in 3 cases. magnetic resonance imaging of the brain showed white matter degeneration in the occipital area in 2 cases and frontal area in 2 cases. CONCLUSION: adrenal insufficiency can be detected by laboratory evaluation despite the lack of symptoms, therefore, the adrenal function should be evaluated in X-ALD at diagnosis for proper management.

6/44. An endocrinopathy characterized by dysfunction of the pituitary-adrenal axis and alopecia universalis: supporting the entity of a triple H syndrome.

We demonstrate the rare disorder of triple H syndrome in a 25-year-old man. He was pointed out as having short stature, at -5.9 s.d., and diagnosed as GH deficient at 6 years old. Approximately a year ago, he noticed systematic hair loss. He lost body weight by 7 kg during the last half year. He was admitted to Jichi Medical School Hospital because of unconsciousness. Physical findings showed disturbance of consciousness with japan coma Scale I-3. He had emaciation and alopecia universalis. Laboratory findings showed plasma glucose was as low as 1.11 mmol/l. GH and ACTH deficiency with hypoadrenocorticism were clarified. His intelligence was in the low normal range with a WAIS IQ of 70, and anterograde amnesia was suggested in the presence of a little, but not significant, morphological change in the hippocampus on a magnetic resonance imaging scan. Replacement by a physiological dose of hydrocortisone normalized plasma glucose, and restored body weight and growth of hair during the 7 month therapeutic period. The present finding strongly supports a clinical entity of triple H syndrome, including ACTH deficiency, alopecia universalis and anterograde amnesia, and that there may be some variation of the triad among the subjects.

8/44. A case of lymphocytic infundibuloneurohypophysitis associated with systemic lupus erythematosus.

A 27-year-old man was admitted to our hospital with facial erythema and general malaise. He had previously suffered from orbital myositis, central diabetes insipidus (DI), peripheral neuritis, and hypogonadotropic hypogonadism. Physical and immunological examinations revealed that he was suffering from systemic lupus erythematosus (SLE). magnetic resonance imaging of the hypothalamic-pituitary region demonstrated a significant enlargement of the pituitary stalk and posterior pituitary. Endocrinological examinations showed that he had not only DI and hypogonadotropic hypogonadism but also hypoadrenalism and hypothyroidism, which were ascribed to the pituitary stalk lesion. Lymphocytic infundibuloneurohypophysitis associated with SLE was diagnosed. Administration of 30 mg/day of prednisolone for one month resulted in a marked reduction of the pituitary stalk thickening and posterior pituitary. It is recommended that a pharmacological dose of glucocorticoid be used in the treatment of lymphocytic hypophysitis patients who show significant thickening of the pituitary stalk and/or a large pituitary mass.

9/44. Adrenal involvement in the antiphospholipid syndrome: clinical and immunologic characteristics of 86 patients.

To describe the clinical and immunologic characteristics of patients with adrenal involvement and antiphospholipid syndrome (APS), we conducted a computer-assisted (pubmed) search of the literature to identify all cases of primary adrenal insufficiency associated with antiphospholipid antibodies published in English, French, and Spanish from 1983 (when APS was first defined) through March 2002. We reviewed 86 patients (80 from the literature plus 6 from our cohort); 55% were male, and the mean age at presentation was 43 +/- 16 years. Sixty-one (71%) patients had primary APS, and 14 (16%) had systemic lupus erythematosus. In 31 (36%) patients, adrenal insufficiency was the first clinical manifestation of APS. abdominal pain was present in 55% of patients, followed by hypotension (54%), fever (40%), nausea or vomiting (31%), weakness or fatigue (31%), and lethargy or altered mental status (19%). The main finding in imaging techniques was compatible with adrenal hemorrhage (59%) and in histopathologic study was a hemorrhagic infarction with vessel thrombosis (55%). lupus anticoagulant was detected in 97% of patients and the anticardiolipin antibodies titer was positive in 93% of patients. Most patients (95%) were positive for the IgG isotype of anticardiolipin antibodies, whereas 40% were positive for the IgM isotype. Baseline cortisol levels were decreased in 98% of patients, ACTH hormone levels were increased in 96% of patients, and the cosyntropin stimulation test was positive in 100% of patients tested. Steroid replacement therapy was the most frequent treatment (84%), followed by anticoagulation (52%) and aspirin (6%). Thirty-two of 35 (91%) patients with prolonged anticoagulant therapy were in good health with a mean follow-up of 25 months, whereas 25 of the 69 (36%) patients with outcome data available had died. The results of the present review stress the clinical importance of systematic screening for lupus anticoagulant and anticardiolipin antibodies in all cases of adrenal hemorrhage or infarction. An initial screening for hypoadrenalism is mandatory in any antiphospholipid antibody-positive patient who complains of abdominal pain and undue weakness or asthenia.

10/44. Adrenal suppression with intranasal betamethasone drops.

Intranasal betamethasone sodium phosphate drops (Betnesol) are frequently used to relieve nasal congestion due to polyposis. We report a case of significant hypothalamic-pituitary-adrenal suppression secondary to the long-term use of intranasal betamethasone drops. This case emphasizes that the topical application of potent corticosteroids may produce systemic effects.
