1.Experimental Studies on the Release of 17-Hydroxycorticosteroids from Soaked Soft Contact Lenses.
Journal of the Korean Ophthalmological Society 1975;16(4):327-330
The therapeutic application of the soft contact lenses are popular in ophthalmic use recently. Drug effects of greater magnitude and duration may be achieved by using a soft contact lens soaked with drugs. Using mycon-soft lenses, with different diameter (14.5mm, 12.0mm) and thickness (0.2mm, 0.1mm), soaked in 2.5% hydrocortisone acetate or 2.5% hydrocortisone succinate for 15 minutes and 30 minutes according to the protocol, and elution studies were performed. Elution rate were not influenced by the thickness of contact lens and soaked time in drugs, but it was influenced by the size of contact lens. It showed that increased elution rate in larger contact lens than smaller one. It was suggested that neither hydrocortisone acetate nor hydrocortisone succinate were absorbed by the soft contact lens but were adhered to the lens surface and released from it gradually.

Congenital adrenal hyperplasia refers to a group of autosomal recessive disorders that is defective in the synthesis of cortisol. The enzymes most often affected are 21-hydroxylase and 11beta hydroxylase. The low levels of cortisol stimulate the pituitary gland to release ACTH. Chronic elevation of the ACTH level causes bilateral adrenal hyperplasia and a secondary increase in androgen formation. We examined a 19 year-old woman presented with clitoral hypertrophy and vaginal spotting. The subjects basal level of serum cortisol was low, but the serum levels of ACTH, 17a-hydroxyprogesterone, deoxy-corticosterone were elevated. The urinary excretions of 17-ketosteroids and 17-hydroxycorticosteroids were also increased. The karyotyping study and transrectal ultrasonography showed normal findings. The patient underwent clitoris reduction surgery and received hydrocortisone. To the best of our knowledge, this is the first case of 11beta-Hydroxylase deficiency in Korea.

Bilateral adrenal tuberculosis is a rare disease and often occurs bilaterally. We report a case of bilateral adrenal masses due to tuberculosis with adrenal insufficiency. The patient was a 39- year-old man who had complained of intermittent pain of right upper quadrant and general weakness. The plasma levels of cortisol and catecholamine were normal. The levels of 24-hour urinary catecholamine and VMA were also normal. But the levels of 24-hour urinary 17- hydroxycorticosteroids and 17-ketosteroids were reduced. Abdominal CT showed about 6.5 x4.8 x 5.4cm sized left adrenal mass and 4.0 x 2.8 x 3.6cm sized right adrenal mass with calcification. The result of sono-guided percutaneous needle biopsy was adrenal tuberculosis. The patient was treated with antituberculous chemotherapy and hormonal replacement. But the masses are unchanged during 5-months follow-up.

PURPOSE: Adrenocortical tumors are uncommon in children and comprise only a small proportion of primary adrenal neoplasms. The biologic behavior of these tumors may be very difficult to predict, and their rarity has hindered identification of clinical characteristics. Patients with functioning tumors have excessive steroid hormone production, and the clinical manifestation depends on the predominant hormone produced. The detection of nonfunctioning tumors is not easy and the diagnosis may be delayed. Benign tumors can be cured by complete surgical excision, but malignant cases have poor response to treatment and worse prognosis. Early diagnosis and proper management are very important because of the large proportion of functioning malignant tumors in children. We report clinical features of adrenocortical tumors in children that may be of help in the early detection, proper management, and assessment of prognosis of patients. METHODS: We reviewed the clinical characteristics of 14 cases of adrenocortical tumors, among 85 children diagnosed with adrenal tumors, who visited the Severance Hospital, College of Medicine, Yonsei University, from January 1970 to July 1996. RESULTS: 85 Patients were diagnosed with adrenal tumors. Among them, 71 cases 83.5%) were tumors of the adrenal medulla, neuroblastoma and pheochromocytoma, and 14 cases (16.5%) were adrenocortical tumors, consisting of 5 cases of adenoma, 7 cases of carcinoma, and 2 cases unspecified. The age distribution ranged from 16 months to 14 years of age, and the mean was 5 years & 11 months (median 4 years & 2 months). Sex distribution revealed a male to female ratio of 1:1.33. The left to right ratio was 3.7:1, showing a left side predominance. 13 Cases (92.9%) were functioning tumors: 12 cases (92.3%) had clinical evidence of androgen excess, among which 6 cases (46.2%) were associated with Cushing's syndrome, and 1 case was compatible with primary aldosteronism. Serum cortisol, urinary 17-ketosteroids and 17-hydroxycorticosteroids concentrations were measured in 11 cases and urinary concentrations of 17-ketosteroids were elevated in all 11 cases (100%), while 17-hydroxycorticosteroids were elevated in 4 cases (36.4%). Abnormalities of serum cortisol were found in all cases except 1: serum cortisol concentrations were abnormally elevated in 5 cases (45.5%), and the remainder (5 cases, 45.5%) showed loss of diurnal variation. Dexamethasone suppression test was performed in 9 cases, and all (100%) showed no suppression. Preoperative radiologic studies included abdominal sonograms, CT or MRI scans, and angiography. Histology showed carcinomas to be bigger and heavier than adenomas, and microscopically carcinomas had necrosis, calcifications, and invasions of vessels. Distant metastases were found in 4 cases (12.7%). Adrenalectomy with complete surgical excision was performed in 12 cases. Long-term follow-up was possible in 10 patients after operation: 3 patients initially diagnosed with adenoma survived without tumor recurrence over a year, and among 6 carcinoma patients, 4 expired within a year, and 2 survived, with one patient currently undergoing postoperative chemotherapy. Of the 10 patients currently under going follow-up, one patient was initially diagnosed with a histologically unspecified tumor, and has survived 4 years after operation. CONCLUSIONS: When adrenocortical neoplasms are suspected by clinical symptoms and laboratory findings, abdominal ultrasonogram, CT or MRI scans must be performed immediately. Early detection and proper management are important for better prognosis, but are often delayed in the majority of cases. Ultimately, pediatricians need to be familiar with clinical characteristics and laboratory findings of adrenocortical tumors, bearing in mind the possibility of diagnosis in children.
