Gonadotropin and Testosterone Secretion in Normal Human Males After Stimulation With Gonadotropin-Releasing Hormone (Gnrh) or Potent Gnrh Analogs Usi…
1978
Gonadotropin-releasing hormone (GnRH) and some potent long-acting GnRH analogs, applied by different routes of administration, were tested in six healthy human males. The effects on gonadotropin secretion were compared with the one after intravenous (i.v.) bolus injection of 25 microgram of GnRH. The net increase of luteinizing hormone (deltaLH) in serum produced by 25 microgram of GnRH i.v. was matched by subcutaneous (s.c.) injection of 100 microgram of GnRH, dissolved in 20% gelatin or without gelatin; 5 microgram of D-Ser (TBU)6-des-Gly10-GnRH-ethylamide i.v.; 5 microgram of D-Leu6-des-Gly10-GnRH-ethylamide i.v.; and 50 microgram of D-Trp6-des Gly10-GnRH-ethylamide given pernasally (p.n…
Subclinical hyperthyroidism due to a thyrotropin receptor (TSHR) gene mutation (S505R).
2006
Aim: To identify the molecular defect by which non-autoimmune subclinical hyperthyroidism was caused in a 6-mo-old infant who presented with weight loss. Methods: Congenital non-autoimmune hyperthyroidism is caused by activating germline mutations in the thyrotropin receptor (TSHR) gene. Therefore, the TSHR gene was sequenced directly from the patient's genomic DNA. Results: Molecular analysis revealed a heterozygous point mutation (S505R) in the TSHR gene as the underlying defect. Conclusion: A constitutively activating mutation in the TSHR gene has to be considered not only in patients with severe congenital non-autoimmune hyperthyroidism, but also in children with subclinical non-autoimm…
Neuroendocrine response to antipsychotics: effects of drug type and gender
1999
Abstract Background: To study the influences of drug type and gender on the neuroendocrine response to neuroleptic treatment, we compared the endocrine actions of two neuroleptics with different receptor affinity profiles—a substituted benzamide, amisulpride, a selective D 2 -like dopamine antagonist; and a thioxanthene, flupenthixol, a mixed D 1 /D 2 -like antagonist also blocking serotonin, H 1 , and D 1 receptors—on anterior pituitary hormone secretion in schizophrenic patients (DSM-III-R). Methods: Blood was withdrawn at 15-min intervals to assess basal secretion of prolactin, growth hormone (GH), and thyroid-stimulating hormone (TSH). Four hundred micrograms of thyrotropin-releasing ho…
Stimulation of Spermatogenesis and Biological Paternity by Intranasal (Low Dose) Gonadotropin-Releasing Hormone (GnRH) in a Male with Kallmann's Synd…
1987
Intranasal (in) GnRH spray caused induction and maintenance of spermatogenesis and biological paternity in a 28-yr-old man with Kallmann's syndrome. Prior treatment had included GnRH analog administration, which failed to induce puberty, and testosterone (T) enanthate weekly. Prior hCG/human menopausal gonadotropin therapy had resulted in high normal serum T levels and near-normal semen quality, but during subsequent hCG therapy, spermatogenesis markedly decreased. The patient had then received 250 mg T enanthate/month for 2 yr and 7 months; it was discontinued 7 weeks before the in GnRH study began. At its start (July 1984) the subject's testis size was 7 mL, and he had azoospermia, low se…
Insulin-like growth factor 1 and pressure load in hypertensive patients
1996
To verify the effect of a pressure load on the production of Insulin-like Growth Factor 1 (IGF1) in essential hypertensives, we studied 15 patients and 8 normotensive controls before and during orthostatism. Upright standing was characterized both in normals and in hypertensives by significant higher rate-pressure product [RPP = systolic blood pressure (mm Hg) x heart rate (beats/min)]. Proportional increases of RPP were significantly related to IGF1 values at the end of orthostatism and to proportional increases of IGF1 in hypertensive group but not in normotensive one. Our results confirm that IGF1 plasma levels in hypertensive patients are related to pressure load.
Testicular Sperm Extraction (TESE) and Intracytoplasmic Sperm Injection (ICSI) in Hypogonadotropic Hypogonadism with Persistent Azoospermia After Hor…
2004
Purpose: We aimed to retrieve testicular sperm to be employed on intracytoplasmic sperm injection (ICSI) cycles on a male affected of hypogonadotropic hypogonadism (HH) that remained azoospermic after long-time hormonal treatment. Methods: Design. We initially performed hormonal therapy using gonadotropins to achieve spermatogenesis. After several semen analyses, we weighed the possibility of looking for testicular spermatozoa for ICSI. Setting. A private university-affiliated setting. Patient. A 30-years-old man diagnosed 10 years ago to suffer from idiopathic, prepubertal HH. Interventions. Gonadotrophin treatment was initiated with hCG and follicle stimulating hormone (FSH). Testicular s…
Clinical course of patients with episodic cluster headache treated with corticosteroids inproximity to the sphenopalatine ganglion: A preliminary stu…
2011
Objective: A study is made of the clinical course of patients with episodic cluster headache following the injection of corticosteroids in the proximity of the sphenopalatine ganglion of the affected side. Study Design: A retrospective observation study was made corresponding to the period between 2006 and 2010. Patients with episodic cluster headache received corticosteroid infiltrations in the vicinity of the sphenopalatine ganglion. Data were collected to assess the clinical course, quantifying pain intensity and quality of life. A total of 23 patients (11 women and 12 men) with a mean age of 50.4 years (range 25-65) were included. Forty percent of the patients had undergone dental extra…
Effect of Corticosteroids on Facial Function after Cerebellopontine Angle Tumor Removal: A Double-Blind Study versus Placebo
2015
The aim of this study was to assess the effect of corticosteroids administered intra- and postoperatively on the occurrence of facial palsy after a cerebellopontine angle (CPA) tumor resection, and to investigate pre- and intraoperative prognostic factors. A multicenter, prospective, randomized, double-blind and versus-placebo study was conducted between 2006 and 2010. Three hundred and ten patients operated on for a CPA tumor (96% vestibular schwannomas, 4% miscellaneous) were included by five participating centers. The population was stratified into patients with small (≤15 mm CPA on axial MRI views) and large tumors. In each group, patients were randomized to receive corticosteroid (1 mg…
Infliximab three-dose induction regimen in severe corticosteroid-refractory ulcerative colitis: Early and late outcome and predictors of colectomy
2014
Abstract Background Infliximab is effective as rescue therapy in severe corticosteroid-refractory ulcerative colitis. The optimal dose regimen and the long term benefits are not well defined. The aim of the present study was to evaluate short- and long-term colectomy rate in a cohort of patients with severe corticosteroid-refractory ulcerative colitis who received a three-dose infliximab induction regimen. Methods One hundred and thirteen patients admitted to 11 Italian IBD referral centres and treated with infliximab according to an intention to treat three-dose regimen were included. The co-primary endpoints were 3- and 12-month colectomy rate. The secondary end-points were the overall co…
Corticosteroid injections, eccentric decline squat training and heavy slow resistance training in patellar tendinopathy.
2009
Udgivelsesdato: Sep-28 A randomized-controlled single-blind trial was conducted to investigate the clinical, structural and functional effects of peritendinous corticosteroid injections (CORT), eccentric decline squat training (ECC) and heavy slow resistance training (HSR) in patellar tendinopathy. Thirty-nine male patients were randomized to CORT, ECC or HSR for 12 weeks. We assessed function and symptoms (VISA-p questionnaire), tendon pain during activity (VAS), treatment satisfaction, tendon swelling, tendon vascularization, tendon mechanical properties and collagen crosslink properties. Assessments were made at 0 weeks, 12 weeks and at follow-up (half-year). All groups improved in VISA-…
