Etiological diagnosis of hyperprolactinemia.

Discuss or comment on this article.
There are numerous etiologies of hyperprolactinemia, a common reason for consultation. Diagnostic measures must be capable of identifying the tumors, the most frequent of which are prolactin adenomas. Hypothalamic-pituitary MRI is the reference morphological examination. In clinical practice, it is usually performed very early, following the discovery of increased plasma concentrations of PRL. This approach is warranted for marked increase in PRL in the absence of drugs with hyperprolactinemic effects (>10 x upper limit of normal) since a diagnosis of PRL adenoma is extremely likely under such circumstances. When hy...

Prolactinoma surgery.

Discuss or comment on this article.
Surgery is generally used as second-line treatment in prolactinomas. For microprolactinomas, it may be indicated in cases of resistance or intolerance to dopamine agonists or where patients prefer definitive cure to lifelong drug treatment. In highly trained hands, selective adenomectomy results in normalization of prolactin levels in 75-90% of cases with little morbidity and no mortality. However, subsequent relapse is possible in up to 20% of cases. In macroprolactinoma, a definitive cure is unlikely due to the frequency of invasive tumor extension. A transsphenoidal or, less frequently, a transfrontal surgical appro...

Prader-Willi syndrome is a rare genetic disorder, affecting 1 out of 25,000 births, in which a critical region of chromosome 15, the 15q11-q13 region, is affected. At birth, PWS infants exhibit severe hypotonia that partially improves, explaining in part suckling and swallowing troubles and the delay in psychomotor development. Characteristic facial features (dysmorphic syndrome) and very small hands and feet are frequently observed at this age. After this initial phase, the most striking signs appear: hyperphagia and absence of satiety often leading to severe obesity in affected children as young as two years. The sit...

Discuss or comment on this article.
The genes encoding the low-density lipoproteins receptor and its ligand apolipoprotein B, have been the only two genes classically implicated in autosomal dominant hypercholesterolemia. We have identified in 2003, the third gene implicated in this disease: PCSK9 (Proprotein Convertase Subtilin Kexin 9). Several mutations (p.S127R, p.F216L, p.D374Y...) of this gene have been reported to cause hypercholesterolemia by a gain of function leading to a reduction of LDL receptor levels. Other variations of PCSK9 are conversely associated with hypocholesterolemia particularly the non-sense p.Y142X and p.C679X mutations found i...

Medullary thyroid carcinoma accounts for 5-10% of all thyroid cancers. It is sporadic in 75% of cases and familial in 25% of cases. Germ-line REarranged during transfection (RET) proto-oncogene mutations are detected in more than 95% of patients with familial medullary carcinoma whereas somatic RET mutations are detected in 40-70% of sporadic medullary carcinomas. Surgery is the only curative treatment and should consist of total thyroidectomy with central and ipsilateral or bilateral lateral lymph node dissection. Surgery provides successful cure in almost 100% of patients when tumor size measures a few millimeters, i...

We present a case of a symptomatic neuroendocrine tumor in a 27-year old woman. The identification of the nature of the neuroendocrine tumors was difficult despite the use of a wide range of diagnostic procedures. This case is interesting in many ways: this is an exceptional illustration of MEN 1 with vipoma associated with calcitonin secretion and it is also a good example of the benefits and limitations of each diagnostic procedure in the heterogeneous group of neuroendocrine tumors.

Turner syndrome occurs in 1:5000 live births (1:2,500 females) and is caused not only by X-chromosome monosomy, but also in a large degree, by the presence of a mosaicism (45,X) and/or an abnormal X or Y chromosome (deletion, isochromosome X, dicentric chromosome). Clinical features are heterogeneous and typical physical anomalies are often mild or absent. In all cases, patients are short but final height has been improved by growth hormone therapy. Ovarian failure, with variable onset depending on the chromosomal anomalies, is frequent. Others visceral diseases (bone anomalies, lymphedema, deafness, and cardiovascular...

Primary lipodystrophies represent a heterogeneous group of very rare diseases with a prevalence of less than 1 case for 100.000, inherited or acquired, caracterized by a loss of body fat either generalized or localized (lipoatrophy). In some forms, lipoatrophy is associated with a selective hypertrophy of other fat depots. Clinical signs of insulin resistance are often present: acanthosis nigricans, signs of hyperandrogenism. All lipodystrophies are associated with dysmetabolic alterations with insulin resistance, altered glucose tolerance or diabetes and hypertriglyceridemia leading to a risk of acute pancreatitis. Ch...

Ageing and reproduction: is polycystic ovary syndrome an exception?

CONCLUSIONS: These clinical observations suggest improved fertility in some PCOS ageing women. The positive impact of ageing on cycle regularisation in PCOS has recently been claimed but the fertility outcome was not evaluated. Ovary ageing results in diminution of the follicular cohort in both normal and PCOS women, associated with decreased inhibin B and anti-müllerian hormone (AMH) levels. Lower inhibin B levels induce FSH enhancement, with a rise in FSH rate per follicle which may determine better follicle maturation, regular and ovulatory cycles in PCOS ageing women. The best proof of this improved fertility was ...

Post-transplantation diabetes (PTD) is a serious complication in organ transplantation: not only does it increase the risk of graft dysfunction; it also increases cardiovascular morbidity and mortality. PTD incidence is correlated with age, non-Caucasian ethnic background, a family history of diabetes, excess weight, hepatitis C infection and steroid boluses for potential rejection. Different mechanisms might explain post-transplantation glucose metabolism disorders: ischemia-reperfusion disorders, whether renal, hepatic or cardiac, are responsible for insulin-resistance, which is increased by post-transplantation ster...

We report the first use of (18)F-fluorodeoxyglucose positron emission tomography (PET) in the follow-up of malignant struma ovarii with persistently elevated serum thyroglobulin level and negative diagnostic iodine 131 whole body scan after thyroidectomy and four courses of 131 iodine. Hilar and mediastinal lymph node uptake was detected but histological verification concluded that there was a false-positive localization corresponding to sarcoidosis lesions without malignant aspect.

Nelson's syndrome was defined in 1958 as the association of an expanding pituitary tumor with high ACTH secretion after bilateral adrenalectomy for Cushing's disease. Pituitary MRI and ACTH measurements led to the definition of Nelson's syndrome as the proliferation of a corticotrophic microadenoma or an aggressive and highly proliferative tumor residue induced by the decreased glucocorticoid inhibition after bilateral adrenalectomy. Now, the problem is not the definition of Nelson's syndrome but rather the identification of markers predictive of tumor growth. Based on a typical case and a review of the literature, we ...

We report on a very rare case of hyperthyroidism due to multiple autonomously functioning bone metastasis of papillary thyroid cancer in a 79-year-old woman. This situation remains extremely uncommon, as shown by our review of the literature; only 47 similar cases have been published from 1946 to 2005. The pathogenic mechanism remains largely unknown in spite of several hypotheses (conjunction in volume and differentiation, auto-antibodies). Hyperthyroidism can be severe, and often T3 levels are markedly more elevated than T4 levels. Apart from hyperthyroidism caused by the hormone-production, clinical features are similar...

Langerhans histiocytosis is a disease with a very diverse clinical spectrum and a very varied prognosis. The thyroid localization is relatively rare, and raises diagnostic and therapeutic difficulties. Diagnosis often requires recourse to clinical, radiological and pathological confrontation. Combined medical and surgical treatment is indicated and requires close multidisciplinary cooperation. On the basis of a new observation and data in the literature, we present a progress report on the clinical and therapeutic options preferred by various authors.

We report the case of a 30-year-old woman, consulting for a painful clitoromegaly which developed progressively and rapidly. The gyneco-endocrinological assessment ruled out hyperandrogenism. Ultrasound examination of the clitoris revealed the presence of a clitoral cyst. Acquired clitoromegaly is a symptom which occurs in severe hyperandrogenism. Other organic etiologies include clitoral cysts of various nature and solid tumors. An ultrasonographic examination should be included in the diagnostic work-up for acquired clitoromegaly.

Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant hereditary syndrome (OMIM 131100) due to MEN1 gene mutations, predisposing to the development of hyperplasic and tumoral lesions of neuroendocrine tissues. Since the identification of the gene in 1997, more than 400 different mutations of MEN1 have been registered. Genotypic analysis of MEN1 remains fastidious and must be reserved to targeted situations. If the lesions appear in a familial assessed context, there is a strong argument to search for MEN1 mutation. This is not the case in a sporadic context. With experience acquired in our laboratory, we ...

Assessment of ovarian reserve in women undergoing assisted reproduction is useful in optimising the treatment protocol. Availability of a reliable measure of ovarian reserve is essential. Currently, serum AMH level seems to be more strongly related to the ovarian reserve and to be ...
