Adrenocortical tumors in childhood.

Adrenocortical tumors (ACT) are rare in childhood. Determination of malignant potential is difficult. To assess the presentation, clinical behaviour, and histology of these tumors in our center, the records of nine patients with ACTs between 1989 and 2000 were analyzed. The age, sex, clinical presentation, investigations, treatment, follow-up data, and current status were determined. The pathological features were reanalyzed by our pathologist. The endocrine profile of the tumors was also retrieved from the records. There were two males and seven females; the median age at referral was 2.5 years. Two patients (one male, one female) presented with clinical features of Cushing's syndrome with hypertension. Four girls had features of Cushing's syndrome with associated virilization. One 11-year-old girl presented with hypertension, hypokalemia, and pseudoparalysis due to an aldosterone-secreting tumor. One girl presented with precocious pubic hair and clitoromegaly. One male had evidence of true precocious puberty. The endocrine profile was available in eight cases: cortisol levels were raised in four, testosterone in four, and aldosterone in one. One boy had pubertal levels of follicle-stimulating hormone and testosterone. Surgery was the only modality of therapy used. Histopathology showed capsular invasion in four patients and vascular invasion in two. The median tumor weight was 80 g (15-550 g) and the size ranged from 1.5 x 1.5 to 12 x 12 cm. Five patients are alive without tumor recurrence at a median follow-up time of 2 years. Tumor recurrence was seen in two patients, one with capsular rupture during surgery and another with a tumor weight of 16 g with associated capsular and vascular invasion. Atypical modes of presentation like pseudoparalysis must be kept in mind. Histologic criteria for malignancy in ACT are unreliable. Tumor weight may not always be accurate in predicting tumor behaviour. Complete surgical excision remains the only effective and potentially curative treatment.

Polyglandular autoimmune syndrome type 1 without chronic mucocutaneous candidiasis in a 16 year-old male.

A 16 year-old boy presented with adrenal crisis and was incidentally found to have features of latent tetany. Also detected were Hashimoto's thyroiditis, alopecia and subnormal T cell function, and he was diagnosed as having polyglandular autoimmune syndrome type 1 (PGA-1), although chronic mucocutaneous candidiasis, a hallmark of PGA-1, was absent. The presentation of several components of this disorder at one time and at this age is uncommon, and the features of overt hypoparathyroidism were probably masked by associated adrenal insufficiency.

Pulmonary mucormycosis presenting with recurrent laryngeal nerve palsy.

Pulmonary mucormycosis is an uncommon infection and its endobronchial form is rare. Fever, cough, dyspnoea and hemoptysis are the usual presenting symptoms. Hoarseness of voice, a rare manifestation of endobronchial mucormycosis, has been reported earlier but its exact anatomical basis was unclear. We report an instance of polypoid endobronchial mucormycosis and vocal cord paralysis in a patient with type I diabetes and diabetic ketoacidosis.

Mucor endophthalmitis.

PURPOSE: To report on a case of type 2 diabetes, with eyelid gangrene and endophthalmitis as a presenting manifestation of rhino-orbito-cerebral mucormycosis. RESULTS: CECT head showed proptosis, mucosal thickening in the ethmoid sinus and hypodense lesions in the frontal and occipital lobes. Vitreous tap showed right angle branched aseptate hyphae consistent with mucormycosis. CONCLUSIONS: A diabetic patient presenting with sudden loss of vision, eyelid gangrene and endophthalmitis, involvement by an angio-invasive fungus-like mucormycosis is an important consideration.

Cisapride improves gallbladder emptying in patients with type 2 diabetes mellitus.

BACKGROUND AND AIMS: Gallbladder motor function is impaired in many patients with diabetes, and may be related to cholinergic nerve damage. Cisapride is a prokinetic drug of the gastrointestinal tract and acts by releasing acetylcholine from cholinergic nerve endings. The aim of this study was to determine the effect of cisapride on gallbladder emptying in patients with type 2 diabetes mellitus (DM). METHODS: Gallbladder emptying and tests for autonomic neuropathy (AN) were performed in 27 patients with type 2 DM and in 10 healthy subjects. Gallbladder emptying was studied by using real-time ultrasonography after an overnight fast, and after the subjects received a breakfast that contained 2500 J. Gallbladder emptying was repeated after the treatment with cisapride (10 mg t.i.d.) for 1 week in all subjects. RESULTS: Abnormal gallbladder emptying was present in 14 (51.9%) patients. The residual gallbladder volume (mean +/- SEM) was higher (9.3 +/- 1.0 vs 4.6 +/- 0.6; P = 0.002), and ejection fraction was lower (57.4 +/- 4.0 vs 74.2 +/- 2.4; P = 0.015) in diabetic patients than it was in healthy subjects. Cisapride produced a reduction in fasting and residual volumes (24.6 +/- 2.4 vs 20.0 +/- 1.4; P = 0.034 and 9.3 +/- 1.0 vs 5.9 +/- 1.1; P = 0.00003, respectively), and an improvement in ejection fraction (57.4 +/- 4.0 vs 72.6 +/- 3.8; P = 0.000007). The improvement in gallbladder emptying after cisapride therapy was confined to the patients with AN (n = 13) (57.3 +/- 5.4 vs 80.4 +/- 2.9; P = 0.0017), suggesting denervation supersensitivity with an upregulation of cholinergic receptors. There was no significant change in the ejection fraction in patients without AN (57.5 +/- 6.1 vs 65.4 +/- 6.5; P = NS). Sex, duration of diabetes, peripheral neuropathy, diabetic retinopathy and serum cholesterol level did not influence gallbladder emptying. CONCLUSION: Impaired gallbladder emptying is common in patients with type 2 DM. Cisapride significantly improves gallbladder emptying in patients with autonomic neuropathy.

Plasma cortisol response to 1 microgram adrenocorticotropin at 0800 h & 1600 h in healthy subjects.

BACKGROUND & OBJECTIVES: Cortisol response to 250 micrograms adrenocorticotropin (ACTH) exhibits no circadian variation. Information on the circadian variation, if any, in cortisol response to 1 microgram ACTH, which is considered as a physiological dose is not available. As the 1 microgram ACTH stimulation test is projected as an outpatients procedure with no time constraint, this information is very important. Hence, this study was designed to assess whether any circadian variability exists in cortisol response to 1 microgram ACTH in healthy subjects. METHODS: Thirty six healthy volunteers (23 male and 13 female) with mean age of 32.2 +/- 9.0 yr were consecutively studied after obtaining informed consent. On day 1, prestimulated and stimulated plasma cortisol samples were collected at 0800 h and, at 30 and 60 min following an intravenous bolus of 1 microgram ACTH, and on day 3, plasma cortisol samples were similarly collected at 1600 h. Cortisol estimation was done by a sensitive and specific radioimmunoassay. Stimulated plasma cortisol of 500 nmol/1 or more was defined as a normal response. RESULTS: The prestimulated and peak cortisol levels at 0800 h (377.5 +/- 93.3 and 729.1 +/- 183.2 nmol/l) were higher (P < 0.001 and P < 0.01) than those at 1600 h (230.1 +/- 75.7 and 665.8 +/- 138.6 nmol/l). However, a stimulated cortisol response of 500 nmol/l or more was observed at both 0800 h and 1600 h in all subjects at 30 min but not at 60 min. The [symbol: see text] (peak-basal) response was higher at 1600 h than that at 0800 h (432.8 +/- 136.8 vs 351.5 +/- 177.3, P < 0.01). INTERPRETATION & CONCLUSION: The demonstration of normal cortisol response to 1 microgram ACTH both at 0800 h and 1600 h suggests that the test can be performed at any time of the day.

Hypoglycemia in small for gestational age babies.

The main objectives of the study were to find the incidence and risk factors associated with development of hypoglycemia in small for gestational age (SGA) babies, to compare haemoglucotest strips (Boehringer Mannheim) with the standard laboratory method (glucose-hexokinase) for estimation of blood glucose, and to measure the insulin and cortisol responses of SGA babies. This was a prospective longitudinal study. The sample included SGA babies and over a period of six months, 127 consecutively born small for gestational age babies were investigated prospectively for development of hypoglycemia in first 48 hrs of life. Plasma samples were taken during episodes of hypoglycemia for insulin and cortisol estimation and compared with non-hypoglycemic controls. The overall incidence of hypoglycemia was 25.2% in SGA babies and 98% of the episodes occurred within first 24 hrs. Compared to non-hypoglycemics, mothers of hypoglycemic babies had higher incidence of receiving i.v. fluids (5% dextrose) during labour. The hypoglycemic babies were more likely to be sick and oral feeds had been initiated by one hour of life in only 37% of them compared to 63% of non-hypoglycemic babies. Plasma insulin/glucose ratio was significantly higher in hypoglycemic than non-hypoglycemic babies, whereas the cortisol levels were similar. Small for gestational age babies are highly prone to develop hypoglycemia in first 24 hrs of life.

A preliminary report on basal & stimulated plasma cortisol in patients with acquired immunodeficiency syndrome.

BACKGROUND & OBJECTIVES: Structural and/or functional alterations in adrenal glands have been reported in human immunodeficiency virus (HIV) infection. However, no information has been reported from India. Hence a study was undertaken to assess the basal and circadian variations in plasma cortisol, and cortisol response to bolus ACTH in patients with AIDS. METHODS: Basal and stimulated plasma cortisol levels at 0800 h and 1600 h and, at 30 and 60 min following an intravenous bolus of 250 micrograms ACTH (short synacthen test, SST) were estimated in 15 patients with AIDS (CD4 < or = 200/microliter) and 12 healthy controls. The nature of the opportunistic infections and/or associated disease in each patient was also studied. RESULTS: The patients had higher median basal plasma cortisol levels as compared to the controls at 0800 h (540 nmol/l vs 415 nmol/l, P < 0.005) and at 1600 h (420 nmol/l vs 285 nmol/l, P < 0.003). Five patients (33%) exhibited abnormal circadian cortisol rhythms. All subjects in the control group and all but one (6.6%) in the patients group had normal peak plasma cortisol response (> or = 550 nmol/l) to SST. The lone patient with subnormal cortisol response had no feature of adrenal insufficiency. On the contrary, 3 patients clinically suspected to have adrenal insufficiency, had normal plasma cortisol response. INTERPRETATION & CONCLUSIONS: These findings suggest that most patients with AIDS have elevated basal plasma cortisol levels with abnormal circadian rhythm in some and normal adrenocortical reserve irrespective of the symptoms/signs of adrenal insufficiency.
