Follow-up measurements of TBII allow, in half of the patients, assessment of the prognosis of GO and, therefore, could be of additional help for the disease management.
The retroperitoneoscopic approach offers an established operative procedure for primary adrenal gland tumors. It allows a detailed view of the adrenal gland and its surrounding region. Therefore clear differentiation between normal and neoplastic adrenal tissue is sometimes possible, permitting a planned, unilateral, subtotal resection of the gland. Between July 1994 and August 1997 primary benign adrenal gland tumors (11 Conn adenomas, 4 phenochromocytomas, 4 Cushing adenomas, 3 hormonally inactive tumors; 2.4 +/- 1.2 cm in size; 8 on the right, 14 on the left) were removed from 22 patients by the posterior retroperitoneoscopic approach maintaining tumor-free portions of the ipsilateral adrenal gland. Two patients suffered from bilateral pheochromocytomas associated with multiple endocrine neoplasia (MEN-IIa) syndrome and had previously undergone complete adrenalectomy of the contralateral gland. Following subtotal resection the operating time and blood loss did not differ significantly (p > 0.05) from that seen with complete extirpation (46 patients operated during the same period). All patients with Conn adenomas and pheochromocytomas were biochemically and clinically cured (follow-up 11 months; range 1-31 months). The four patients with Cushing adenoma currently require decreasing cortisol substitution. In the two MEN-II patients adrenal gland cortical function could be maintained; one patient is on low-dose steroid supplementation and the other on none. No local recurrence of tumors has been observed. In selected cases the retroperitoneoscopically performed subtotal adrenal gland resection is a safe procedure that can potentially maintain the function of the adrenal gland cortex.
The frequency, predisposing factors and course of agranulocytosis (granulocytes < 250/microliter) secondary to antithyroid drugs were studied in a cohort of 1256 continuously treated outpatients with hyperthyroidism during the 15 year period from 1973 to 1987. Two cases of agranulocytosis were detected; the frequency was 0.18% (95%-confidence intervals, 0.0-0.44%). This prevalence appears to be lower than reported in previous studies (up to 1.8%). For other adverse drug reactions, there was a clear-cut relationship to initial thionamide dose and to the body mass index; most reactions occurred during the first weeks of treatment. In addition, eight patients referred for thionamide drug- induced agranulocytosis were studied, and the following results obtained: Methimazole dose in patients with agranulocytosis was almost twice as in other patients (63.3 +/- 19.7 vs 34.3 +/- 29.7 mg daily) suggesting that this complication was related to dose. The interval between start of antithyroid drug treatment and first symptoms of agranulocytosis was 33 days (median; range, 23-55 days); hence, prolonged treatment beyond this period would appear relatively safe. Withdrawal of the causative agent and treatment of infection led to recovery of leukocyte counts within 15 days (median; range, 5-31 days). Two fatal outcomes were seen in referred patients. In one severely hyperthyroid patient with methimazole-induced agranulocytosis, recombinant human granulocyte/macrophage colony stimulating factor induced clinical and hematologic recovery within a few days of administration. In conclusion, agranulocytosis is the most severe side effect of antithyroid drugs. According to our results and a literature review, it occurs almost exclusively during the first ten weeks of treatment and is probably related to the drug dose.(ABSTRACT TRUNCATED AT 250 WORDS)
T-pellets are the androgen formulation with the longest biological action and strongest pharmacodynamic efficacy in terms of gonadotrophin suppression. The pharmacokinetic features are advantageous compared to other T preparations and the patient acceptance is high.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
