Influence of the ovary on parameters of LH secretion during the recovery from buserelin-induced desensitization
Abstract This study examined the effect of the ovary on LH pulsatility and on the secretory performance of gonadotrophes during the phase of recovery after treatment with buserelin, a GnRH analogue. We included 12 patients, who received buserelin (1.2 mg/day, intranasally for 3 months) as a reductive therapy for uterine leiomyomatosis prior to hysterectomy. Six patients were oophorectomized and the other 6 patients had their ovaries preserved. LH was measured in samples taken basally up to 36 days after suppression of buserelin. LH pulsatility was studied on day 9 along a 24-h cycle, and the response of the hormone to a double-stimulus GnRH test on days 0, 9, 20, and 34. The concentration o…
Consideraciones diagnósticas sobre el llamado síndrome del pulmón hiperclaro unilateral (síndrome de Swyer-James o de Mc-Leod)
Swyer-James-MacLeod Syndrome (SJMS) is considered to be a relatively uncommon and complex disease characterized by roentgenographic hyperlucency of one lung, lobe, or part of a lobe, due the pulmonary vascular structure and alveolar overdistension. It is sometimes associated with bronchiectasis. This syndrome seems to be an acquired disease that develops after viral bronchiolitis and/or viral pneumonia in early childhood. Microscopically, there is evidence of patchy bronchitis and bronchiolitis.SJMS is usually asymptomatic and discovered accidentally by chest radiography in a child with respiratory symptoms and should be differentiated from other causes of unilateral hyperlucency on chest r…
