E-mail messages can be effective to make the health education activity of family pediatricians more effective.

Background: Not all family pediatricians carry on their health education tasks constantly and they do not often use effective communication strategies. To deal with this situation it is useful to find ways that are easy to implement, reproducible in the most diverse contexts and that can be accepted even by the least motivated pediatricians. We have been experimenting a training method, based on sending a series of e-mail messages, assessing their feasibility and effectiveness. Study design: Experimental approach. Methods: The intervention consisted of sending 21 email to 141 family pediatricians. In order to assess the intervention effectiveness, we first select randomly 20 pediaticians out of the 141 and before the intervention we interviewed in their offices 400 parents of 2-14 years-old children (20 parents for each of the 20 family pediatricians); similary 5-6 months after the intervention, we selected randomly other 20 pediatricians and interviewed 355 parents. The emails mentioned the 5 A's model as well as the motivational interview, the model of the stages of change and the counseling techniques. They also enclosed communication material to be reproduced and given to the parents, as well as recommendations and guidelines. Five messages contained self-assessment tests. Results: Following the intervention, out of 26 questions asked to mothers, there was a significant improvement in the response to 10 questions and a worsening in the response to a single question. The overall difference between before and after the intervention is very significant (p <0.0001). Conclusions: The intervention was proved to be very effective and easily reproducible. It is necessary to confirm these findings with further studies based on the use of a control group too. It appears to be the first time that email messages are sent in order to train family pediatricians on the behavior change counseling.

Discordant biological parameters of remission in acromegaly do not increase the risk of hypertension or diabetes: a study with the Liege Acromegaly Survey database.

PURPOSE: Acromegaly is a rare disease due to growth hormone (GH)-secreting pituitary adenoma. GH and IGF-1 levels are usually congruent, indicating either remission or active disease; however, a discrepancy between GH and IGF-1 may occur. We aimed to evaluate the outcome of diabetes mellitus (DM) and hypertension (HT) in acromegalic patients with congruent GH and/or IGF-1 levels vs. discordant biochemical parameters. METHODS: Retrospective analysis of the data of 3173 patients from the Liege Acromegaly Survey (LAS) allowed us to include 190 patients from 8 tertiary referral centers across Europe, treated by surgery, with available data concerning DM and HT both at diagnosis and at the last follow-up (LFU). We recorded the number of anti-HT and anti-DM drugs used at the first evaluation and at LFU for every patient. RESULTS: Ninety-nine patients belonged to the REM group (concordant parameters), 65 patients were considered as GHdis (high random GH/controlled IGF-1), and 26 patients were considered as IGF-1dis (high IGF-1/controlled random GH). At diagnosis, 72 patients (37.8%) had HT and 54 patients had DM (28.4%). There was no statistically significant difference in terms of the number of anti-HT and anti-DM drugs at diagnosis versus LFU (mean duration: 7.3 ± 4.5 years) between all three groups. CONCLUSION: The long-term outcome of DM and HT in acromegaly does not tend to be more severe in patients with biochemical discordance in comparison with patients considered as in remission on the basis of concordant biological parameters, suggesting that patients with biochemical discordance do not require a closer follow-up.

Contrôle de l'axe gonadotrope : nouveaux aspects physiologiques et thérapeutiques: Control of the gonadotrope axis: new physiologic and therapeutic aspects.

The endocrine and exocrine functions of the gonads are controlled by the gonadotrope axis, whose master regulator is the hypothalamic decapeptide GnRH. The Kisspeptin/Neurokinin B (Kp/NkB) neuronendocrine system is the main physiologic regulator of GnRH neurons. The Kp/NkB system is currently considered the key mediator for the hypothalamic negative feedback exerted by sex steroids and prolactin, as well as by various metabolic signals. Intrinsic alterations or regulatory abnormalities of Kp/NkB system lead to various gonadotrope axis puberty and fertility dysfunctions. Molecular inactivations of Kp/NkB system actors are associated with some forms of congenital hypogonadotropic hypogonadism without anosmia. The Kp/NkB System is also involved in a few forms of precocious puberty. Finally, the Kp/NKB system is also implicated in gonadotrope axis alterations leading to functional hypothalamic amenorrhea or hyperprolactinemia. NkB is particularly and directly involved in vasomotor menopausal hot flushes mechanism. Various Kp/NkB agonist/antagonist compounds have been developed during the last ten years, and are currently being evaluated in humans. These molecules have potential applications not only in rare genetic diseases with Kp/NkB alterations, but also in various gonadotrope axis-related diseases or in vitro fertilization. The administration of NkB antagonists in menopausal women represents a real therapeutic advance because of their impressive effect in controlling vasomotor menopausal hot flushes.

Raloxifene induces cell death and inhibits proliferation through multiple signaling pathways in prostate cancer cells expressing different levels of estrogen receptor α and ß.

Raloxifene (RAL), a selective estrogen receptor (ER) modulator (SERM) seems to induce apoptosis in both androgen-dependent and -independent prostate cell (PC) lines via activation of ERß and an antagonistic effect on ERα. In this study, we evaluated the effects of RAL on epithelial PC growth using the two following in vitro models: the androgen-dependent cell line EPN which expressed both ERs; and a stabilized epithelial cell line derived from a prostate cancer specimen (CPEC), which expressed low levels of ERß and lacked ERα. In EPN cells, there was an increase in the pre-G1 apoptotic peak and a reduction in the S phase of the cell cycle with G0/G1 arrest after E2 or RAL treatment; bcl-2 mRNA and Bcl-2 protein levels were significantly reduced, while activated caspase-3 and Par-4 levels increased significantly after either E2 or RAL treatment; in addition, c-myc transcript was inhibited after 10(-6) M RAL treatment. A dose-dependent increase of metallothionein II gene RNA level was also induced by RAL in EPN. In CPEC, there was only a weak apoptotic peak associated with caspase-3 activation and Par-4 increase after either E2 or RAL treatment; while c-myc transcript level increased. RAL induced a rapid but transient phosphorylation of ERK 1/2 in EPN cells but generated a sustained effect in CPEC. These findings suggest that RAL effects on PC growth control in vitro are cell-specific, depending on ERß or ERß/ERα relative expression levels. Moreover, this study demonstrated that RAL affected both transcriptional regulation and non-genomic signals, which resulted in the modulation of multiple signaling pathways of apoptosis and of cell cycle progression.

Efficacy of recombinant human follicle stimulating hormone at low doses in inducing spermatogenesis and fertility in hypogonadotropic hypogonadism.

BACKGROUND: Recombinant-FSH (rFSH) added to hCG at dose of 450 IU weekly is effective in inducing spermatogenesis in patients with hypogonadotropic hypogonadism (HH), but there are no data on the use of lower doses. AIM: This observational retrospective study evaluated whether 150-225 IU of rFSH weekly were able to induce spermatogenesis in HH men who failed to start it with hCG alone. SUBJECTS AND METHODS: Thirty-four patients with pre-pubertal onset HH (20-44 yr old) without adverse fertility factors were considered for this study. After hCG pre-treatment they received also either rFSH (Group 1) or highly purified urinary FSH (hpFSH) (Group 2) 75 IU sc 2 or 3 times weekly. Semen analysis was performed every 3 months during pre-treatment and the 1st yr of combined therapy. Patients were also invited to refer pregnancies in their partners during the subsequent 12 months. RESULTS: Total sperm count/ejaculate did not show significant difference between 2 groups, while a significantly higher forward motility was observed in Group 1 (p<0.05). The median times to achieve sperm output thresholds (first sperm appearance, sperm concentration >1.5 or >5 mil/ml) were significantly lower in Group 1 (p<0.04, 0.03, and 0.001, respectively). A tendency to a shorter time to pregnancy was shown in partners of Group 1. CONCLUSIONS: Our data indicate that lower rFSH week dose than that so far used was able to induce potentially fertilizing sperm output in HH men previously treated with hCG. The rFSH effects are comparable to those of hpFSH but with a trend to a faster outcome achievement.

Correlation between complication rate and perioperative risk-factors in superior pedicle reduction mammaplasty: our experience in 127 patients.

Reduction mammaplasty, one of the most common plastic surgery procedures, has been shown to confer significant sustained health benefits for patients with symptomatic breast enlargement providing a remedy for back, neck, and shoulder pain. Unfortunately, operations of breast reduction may lead to patient dissatisfaction for poor aesthetic outcome due to complications. Complications, including infection, hematoma, seroma, dehiscence, fat necrosis, and skin loss, may occur in as many as 50% of patients. Unacceptable scarring has also been reported. Complication data revealed several significant features, although there isn't much objective evidence to support that. Over the period 2004-2008, 127 consecutive patients were admitted for breast reduction surgery, data have been analyzed retrospectively to determine whether any correlation could be found between complication rate and perioperative risk-factors using a multifactorial ANOVA F-test. Analysis of variables associated with complications showed that, after adjusting for age and smoking status, only BMI was associated with any complication (p < 0.05). By power analysis, based on a comparison of three proportions, a power of 92% with a significance level of 0.05 was found for the hypothesis that the outcomes of the procedures depends on BMI.

Seminal anti-Müllerian hormone level is a marker of spermatogenic response during long-term gonadotropin therapy in male hypogonadotropic hypogonadism.

BACKGROUND: In adult men, anti-Müllerian hormone (AMH) levels are higher in semen than in serum, but the significance and control of its seminal secretion are still unknown. This study evaluated seminal and serum AMH levels during long-term gonadotropin therapy in men with hypogonadotropic hypogonadism (HH). METHODS: A total of 20 men with never treated prepubertal-onset HH received i.m. hCG to normalize testosterone (T) and induce puberty. Afterwards, 11 of them, requiring fertility, were treated with HCG plus recombinant FSH (rFSH) (75 IU) twice a week, whereas 9 continued to receive hCG alone for 12 months. Before and during therapy, serum AMH, inhibin B and T levels were assessed. Semen samples were also collected during therapy for sperm count and seminal AMH assay. RESULTS: HCG alone decreased basal high serum AMH and stimulated T and inhibin B levels. rFSH plus hCG increased seminal AMH levels, which were consequently significantly higher than with hCG alone, and positively correlated to sperm densities and testicular volumes at 3 and 12 months (P < 0.001). CONCLUSIONS: Our data demonstrate that rFSH, added to hCG, stimulates seminal AMH and spermatogenesis in HH. Thus, seminal AMH levels are under T and FSH control and are closely related to progression of spermatogenesis. Our results also suggest that an early seminal AMH increase may be a marker of good future response to gonadotropin therapy in HH.

Case report: laparoscopic cholecystectomy in situs viscerum inversus.

Situs viscerum inversus is a rare condition, in which the organs are transposed from their normal location in the opposite side of the body. The inversion of L-R asymmetry may be complete (SVI totalis) or partial (SVI partialis), whereby transposition is confined to either the abdominal or thoracic viscera. The authors report a case of videolaparocholecystectomy for cholelithiasis successfully performed on a 41-year-old Caucasian woman with situs viscerum inversus totalis. The patient was discharged on the 2nd postoperative day. The symptomatology disappeared right after the intervention, and still now, after a follow-up of six months, is absent. The procedure was safely performed on the patient with no particular difficulties, except for the reverse position of the angle between the operating and exposing trocars, which led to a difficult approach to the Calot triangle when using the right hand of the surgeon.
