RESUMO
Objective:To investigate the clinical characteristics and offer diagnostic and therapeutic approaches for adult-onset idiopathic hypogonadotropic hypogonadism(AIHH).Methods:Clinical, laboratory, and imaging data, as well as follow-up information, of three male patients diagnosed with AIHH at the Department of Endocrinology and Metabolism of Nanfang Hospital, Southern Medical University, were systematically reviewed and analyzed.Results:All three patients were male, with a median age of 39 years(range, 22 to 40). Two patients reported symptoms of enlarged breasts and reduced sexual function, while one case solely reported a decline in sexual function. Physical examination showed that the median length of the penis was 6 cm(range, 5 to 6 cm), and the bilateral testicular volume was 7.96 mL(4.70-8.82 mL). Basal hormone levels at the time of initial visit to our hospital as follows: the median testosterone level was 0.32 ng/mL(0.24-2.96 ng/mL), median follicle stimulating hormone(FSH) level was 0.56 mIU/mL(0.1-0.75 mIU/mL), and the median luteinizing hormone(LH) level was 0.69 mIU/mL(0.1-1.03 mIU/mL). The levels of other hormones secreted by the anterior pituitary gland were normal. Hypothalamic-pituitary magnetic resonance imaging(MRI) showed that 1 patient had a pituitary microadenoma. Three patients were treated with pulsatile GnRH or gonadotropins, one of which had hypothalamic-pituitary-gonadal(HPG) axis function reversal after GnRH pulse pump therapy and lasted for 1 year, but then still had irreversible reduction.Conclusion:AIHH is marked by adult-onset disease and idiopathic hypogonadism. Enhancing fertility remains a critical requirement for these patients. Pulsatile GnRH treatment or gonadotropin therapy, as viable treatments, exhibit therapeutic effects, albeit with occasional fluctuations. Therefore, the emphasis lies in the timely consideration of fertility preservation.
RESUMO
Objective:To evaluate the effect of short-term topical administration of atropine eye drops with various concentrations and frequencies on eye safety in children.Methods:A double-blind randomized controlled trial was conducted.Sevevty-two children with ametropia or pre-myopia (72 eyes) were enrolled in Tianjin Medical University Eye Hospital from December 2020 to January 2022.The subjects were randomly divided into 0.01% atropine group, 0.02% atropine group and 0.04% atropine group according to a random number table, with 24 cases (24 eyes) in each group.Automatic refraction with an automatic computer optometry device, subjective refraction with a phoropter, intraocular pressure with a non-contact tonometer, axial length by optical biometrics, the amplitude of accommodation (AMP) by the push-up method, pupil diameter with pupilometer, near visual acuity at 33 cm with a standard logarithmic visual acuity chart, tear evaluation with Keratograph 5M and Ocular Surface Disease Index (OSDI) questionnaire survey were performed among all subjects.One drop of 0.01%, 0.02%, and 0.04% atropine was administrated to the study eye according to grouping, and the pupil diameter was measured every 10 minutes until the pupil did not enlarge three times, then the data after a single treatment of the three groups were recorded.After one-week application of the corresponding concentration of atropine eye drops once at night, the data after one-week treatment were recorded.For the next week, the application frequency of 0.01% and 0.02% atropine groups changed to once daily in the morning and evening, and 0.04% atropine group maintained once at night, then the data after two-week treatment were recorded.Data of the right eyes were analyzed.The changes in pupil diameter, AMP and other eye parameters before and after atropine eye drops of the three groups were compared.This study adhered to the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2020KY[L]-51). All subjects and their guardians were fully informed of the method and purpose of this study before entering the cohort.Written informed consent was obtained from guardians.Results:Pupil diameters of 0.01%, 0.02% and 0.04% atropine groups were (5.59±0.48), (5.35±0.76) and (5.65±0.43)mm before treatment respectively, (7.00±0.68), (7.17±0.58) and (8.40±1.71)mm after a single treatment, (6.67±0.62), (6.56±0.65) and (7.60±0.69)mm after one-week treatment, (6.96±0.49), (7.04±0.53) and (7.60±0.36)mm after two-week treatment.There were significant differences in pupil diameter at different time points after treatment among the three groups ( Fgroup=9.430, P<0.001; Ftime=156.620, P<0.001). The AMP of 0.01%, 0.02% and 0.04% atropine groups were (12.94±3.02), (13.25±2.81) and (13.42±2.60)D before treatment respectively, (11.62±2.61), (11.53±2.06) and (9.64±1.93)D after a single treatment, (11.14±2.61), (11.33±2.33) and (8.30±1.18)D after one-week treatment, (9.99±1.81), (8.72±1.25) and (8.76±2.12)D after two-week treatment.There was no significant difference in the AMP among the three groups ( Fgroup=2.800, P=0.063). In the three groups, the AMP at different time points after treatment were significantly lower than that before treatment ( Ftime=61.400, P<0.001). There was no difference in spherical equivalent refraction, intraocular pressure, near visual acuity, axial length, first none-invasive tear break-up time, average none-invasive tear break-up time, tear meniscus height and OSDI score among the three groups ( Fgroup=0.030, 0.630, 1.420, 0.580, 0.140, 0.120, 0.340, 0.142; all at P>0.05). There were significant differences in spherical equivalent refraction, intraocular pressure, first none-invasive tear break-up time, average none-invasive tear break-up time, tear meniscus height and OSDI score at different time points between before and after medication among the three groups ( Ftime=12.560, 4.730, 4.720, 5.220, 3.720; all at P<0.05). Conclusions:Varying pupil dilation and AMP reduction occur after the use of different concentrations of atropine and are more severe at higher concentrations.Increased administration frequency of atropine is associated with more pupil dilation and AMP reduction, but there is no intolerable adverse effect.
