Management of presumed benign ovarian tumors: updated French guidelines

Ultrasound is sufficient for characterizing a unilocular anechoic cyst smaller than 7cm (Grade A). Magnetic resonance imaging is the recommended second-line investigation for indeterminate masses or masses larger than 7cm (Grade B). Serum CA-125 assay is not recommended for first-line diagnosis in adult women (Grade C). In women with a unilocular anechoic cyst, hormone therapy is ineffective and not recommended (Grade A). Ultrasound-guided aspiration is not recommended (Grade B). Abstention is an option in adult women with a unilocular asymptomatic anechoic cyst smaller than 10cm and no history of cancer (Grade B). If symptoms develop, laparoscopy is the gold standard for surgical treatment of PBOT (Grade A). Conservative surgical treatment (cystectomy) should be preferred to oophorectomy in pre-menopausal women without a previous history of cancer...

This article describes the surgical technique and principal complications, and reviews the literature to compare this technique with other methods of repair, particularly the Davydov technique.

C'est un désordre hormonal complexe marqué par une production excessive d'androgènes ovariens ou, plus rarement surrénaliens. Le début des signes est souvent insidieux et souvent négligé au moment de la puberté. L'hirsutisme et l'acné sont les principales manifestations cutanées de l'hyperandrogénie. Ils sont diversement associés à des troubles du cycle menstruel et/ou une prise de poids. Le dosage des androgènes ainsi que l'imagerie permet de faire le diagnostic de l'origine ovarienne ou surrénalienne. Le syndrome des ovaires polykystiques débute à l'adolescence, au moment de la maturation ovarienne. Sa prise en charge précoce est nécessaire pour prévenir les troubles du cycle et éviter l'apparition d'une hypofertilité et d'un syndrome métabolique. Par ailleurs, il peut s'agir d'une hyperplasie surrénalienne à révélation tardive qui va nécessiter un traitement adapté. © 2006 Elsevier Masson SAS. Tous droits réservés.

Comparison of Exercise Testing and 24-HOUR Growth Hormone Secretion in 42 Children with Growth Retardation

The severity of this condition ranges from death before hospital admission to clinical stability resulting in delayed management. Diagnosis is difficult because there is sometimes no evidence of external trauma, in spite of severe chest crush injury and consecutive rupture of airways. Here, we report the case of a 32-month-old girl whose torso was crushed by a van, resulting in bilateral bronchi disconnection. She was admitted to our hospital with cardiac and respiratory arrest. After prompt resuscitation, flexible bronchoscopy permitted the accurate visualization of the rupture and its extent. The life-saving procedure consisted of surgical repair using extracorporeal membrane oxygenation (ECMO) as ventilatory support. This provided rapid relief from the injury, which was previously expected to result in death. These data suggest that ECMO could be beneficial as supportive therapy for selected paediatric patients with major tracheobronchial traumas.
Auxological and Endocrine Evolution of 28 Children with Prader-Willi Syndrome: Effect of GH Therapy in 14 Children

Half of them received growth hormone (GH) therapy (group 2). The spontaneous auxological evolution was analyzed in the two groups from 2 to 8 years; the mean SDS for height remained stable (-0.6 +/- 0.6) in group 1 and decreased (from -2.0 +/- 0.9 to -2.7 +/- 0.6) in group 2. Magnetic resonance imaging showed marked pituitary hypoplasia in the two groups. In group 2, the mean GH peak after two provocative tests was 3.8 +/- 2.4 microg/l, the mean SDS values for insulin-like growth factor I levels were -2.0 +/- 1.5 (range from -0.5 to -5.0). The mean duration of GH treatment was 3.6 +/- 2.9 (range 1-9.3) years. 14 children completed 1 year of treatment. The two groups had opposite evolutions in Delta SDS for height (-0.8 +/- 0.8 vs. +1.1 +/- 0.8), for growth velocity (-1.9 +/- 2.2 vs. +2.9 +/- 2.7), and for Z score of the body mass index (+0.37 +/- 1.3 vs. -0.14 +/- 0.76; group 1 vs. group 2). This retrospective study shows that, in children with Prader-Willi syndrome and true GH deficiency, long-term GH therapy is effective in increasing growth velocity and in maintaining body mass index.

We studied 22 children (13 boys, nine girls) aged at the first clinical manifestations from 2 days to 10 years (average = 5.33 +/- 2 years). Pituitary stalk transection was assessed by the means of magnetic resonance imaging (MRI). The children's past history showed fetal distress in 12 cases (54.5%), cranial trauma in three (13%) and a midline anomaly in three (13%). The first clinical manifestations were neonatal hypoglycemia (two cases), decreased growth velocity (18 cases) and diabetes insipidus (two cases). GH deficiency was complete, present from the onset in 19 of 22 cases and isolated in four. Fifteen of 22 cases had adreno-corticotrophic hormone (ACTH) and thyroid stimulating hormone (TSH) deficiency. Diabetes insipidus was present in six cases and revealed the syndrome in two. All children older than normal age of puberty (n = 10) had gonadotropin deficiency. In our study, these ho...
[Androgen test: comparison of a low test and a high test in the development of the penis in male pseudohermaphroditism]

However, there is a wide range of testosterone dosage and no standardized test. Two doses (2.5 mg and 100 mg) of testosterone heptylate were used in six cases of male pseudohermaphrodism with sexual ambiguity and small penis (ages 6 to 18 months). The clinical results were compared with those of the study of androgen receptors. In two cases, both low-dose and high-dose tests resulted in only minimal changes in the penis. In two cases, the low-dose test gave a good result which was confirmed by the high-dose test; on the other hand, in two cases, the low-dose test was considered to be negative whereas the high-dose test led to the development of a normal-sized penis. In all cases except one, there was good concordance between the results of study of androgen receptors and those of the clinical test. The high-dose androgen test is thus useful in both diagnosis and treatment and facilitates the gender assignment.

The majority of follicles disappears prematurely after a normal determination of the ovary. This results from an accelerated loss of oocytes from the ovaries after the 18th week of fetal life or over a few postnatal years, usually before the onset of puberty. The cause and mechanism of this loss are unknown. X chromosomal anomaly due to deletions or haploinsufficiency of genes can explain the various degrees of ovarian failure. Spontaneous puberty occurs in 20-30% of Turner syndrome patients and their fertility rates vary from 5 to 10%. This indicates the possible presence and maturation of follicles in their ovaries in adolescence. In ovarian failure, the hormone replacement therapy (HRT) is necessary to achieve the development of normal female sexual characteristics, the self image or social functioning and to prevent osteoporosis. Pregnancy is now possible with oocyte donation. A careful cardiovascular follow-up is ne...
