The radiopharmaceuticals are products that combine two very stringent regulatory requirements from two different authorities: as medicine from a pharmaceutical point of view (Afssaps) and as radioactive source with specific authorization (ASN). This article discusses the different regulatory constraints imposed by these authorities but suggests also that legislation is supposed to be modified in the coming years in collaboration with nuclear physicians and their Society (SFMN). 相似文献

This paper describes the sexological examination of spinal cord injured men. The complete exam includes a clinical interview, neurological examination, an EMG of the pelvic floor, a urodynamic examination and ano-rectal exploration, and the objective recording of the man’s sexual response to reflex and psychogenic professionals or psychologists and sextherapists can proceed with a more thorough interview which evaluates number of the elements of the physical examination. The results of the investigation give rise to a number of clinical entities described in terms of lesion levels with respect to the innervation of the reproductive system. Lesions can therefore be classified as being located above the two pathways of erection, or extended to the cauda equina. Each lesion type is associated with a given pronostic of erectile and ejaculatory function. The accompanying physiological recording of penile responses further helps to establish a differential diagnosis between an exclusively organic dysfunction or a primarily psychogenic dysfunction in spinal cord injured men. 相似文献

We report three cases of ovarian psammocarcinoma, which is a serous adenocarcinoma having psammoma calcifications. The FDG uptake in the psammomatous lesions is due to the tissular part of the lesion and the technetium-99m labelled agents uptake to its calcified part. Calcifications are detected on CT scans. Therefore, they are relatively simple to diagnose by nuclear medicine which is useful given relatively the better prognosis of the psammomatous ovarian serous carcinoma when compared to the serous one. 相似文献

In this article, the paraplegics’ possibilities for procreation will be examined. A first chapter will deal with the testicle functioning along with the study of hormonal measuring and testicle histology (study involving 100 patients). As a result, it appears that, after a testicle biopsy, there is a testicle lesion of neurological origin that is sometimes irreversible. On the contrary, the endocrinal testicle lesions have proved reversible under stimulation or spontaneously. A second chapter will deal with the different techniques to obtain an ejaculation and the semen analysis. The techniques that were used being: massage by vibrator, electroejaculation, ejaculation through pharmacological stimulation. The study focuses on 124 ejaculatory tests among which 64 forward ejaculations (52%) and 4 bachward ejaculations (3%) were obtained. The resulting semen analysis revealed a spermatozoon count greater than 20 millions per millilitre (that is 51,5%) and smaller than 5 millions in 11 cases (16%). 相似文献

The testis migrates to a scrotal location before birth. This physiological descent is associated with a reduction in the temperature of the testicular environment since the temperature of the scrotal cavity is lower than that of the body one. This leads to the etablishment of a themperature gradient between the testis and the body which already exists in prepubertal boys. In cases of testicular maldescent (cryptorchidism), the temperature of the testis in its cryptorchid location is much higher than that of the normally descended contrlateral testis. However, there are no data obtained from human studies to establish wether the increased temperature of a cryptorchid testis is responsible for the spermatogenic perturbations typically observed. Nor do we know wether the relocation of a cryptorchid testis to the scrotum permits re-establishment of a normal testicular temperature. Adult men with a history of cryptorchidism constitute about 10% of infertile men, and among these previously cryptorchid infertile men 45% have an abnormally elevated scrotal temperature. This abnormal increase in scrotal temperature is a negative risk factor for fertility: these men have smaller testicular volumes, a more severely impaired spermatogenesis and a higher prevalence of primary infertility than previously cryptorchid infertile than previously cryptorchid infertile men with normal scrotal temperature. However, data provided until now do not allow to know whether elevated temperature is due to the decreased testicular size (hypotrophy) or is a consequence of cryptorchidism per se. 相似文献

Attempts to prepare 1,2:5,6 and 2,3:5,6 di-unsaturated sugars starting from 3,4,6-tri-O-acetyl-1,5-anhydro-1,2-dideo xy-d-arabino-hex-1-enitol or from ethyl 4,6-di-O-acetyl-1,5-anhydro-2,3-dideoxy-α-d-erythro-hex-2-enopyranoside led to 1,5-anhydro-1,2,6-trideoxy-l-threo-hex-5-enitol and its 3,4-diacetate. Hydrogenation and hydrogenolysis of the unsaturated chloro and fluoro derivatives afforded 1,5-anhydro-1,2,6-trideoxy-d-arabino-hexitol and ethyl 4-O-acetyl-2,3,6-trideoxy-α-d-erythro-hexopyranoside. 相似文献
