In order to estimate the impact of laparoscopic stripping of endometriomas on the ovarian follicular reserve, 43 normo-ovulatory women were studied by endocrine (anti-Müllerian hormone (AMH), FSH, LH, inhibin B, oestradiol) and ultrasonographic (antral follicle count (AFC)) methods before surgery, and 3 and 9 months after surgery. The operation was performed by experienced laparoscopists, particularly aware of the need to avoid damaging the healthy part of the ovary. Serum AMH concentrations significantly decreased after the operation (1.4±0.2 ng/ml after 3 months and 1.3±0.3 ng/ml after 9 months versus 3.0±0.4 ng/ml before surgery; P<0.0001), whereas basal FSH, LH, oestradiol and inhibin B concentrations remained unchanged. The volume of the operated ovary significantly diminished after surgery (P<0.0001), whereas the AFC was not significantly altered. Overall, the data show that laparoscopic stripping of endometriomas reduces ovarian reserve. The significant decrease of AMH after surgery confirms that part of the healthy ovarian pericapsular tissue, containing primordial and preantral follicles, is removed or damaged despite all the surgical efforts to be atraumatic. This must be carefully considered when laparoscopic cystectomy surgery is scheduled for patients with no relevant symptoms besides infertility or with already small ovarian reserve.

We evaluated the effectiveness and the cost of axillary staging in breast cancer patients by ultrasound-guided fine-needle aspiration cytology (US-FNAC), sentinel node biopsy (SNB), and frozen sections of the sentinel node to achieve the target of the highest number of immediate axillary dissections. From January 2003 through October 2005, a total of 404 consecutive eligible breast cancer patients underwent US-FNAC of suspicious axillary lymph nodes. If tumor cells were found, immediate axillary dissection was proposed (33% of node-positive cases). If US or cytology was negative, SNB was performed. Frozen sections of the sentinel node allowed immediate axillary dissection in 31% of node-positive cases. The remaining 36% underwent delayed axillary dissection. We compared our policy with clinical evaluation of the axilla, showing better specificity of US-FNAC, the cost balanced by a 12% reduction of SNBs, and a marked reduction of unnecessary axillary dissections resulting from false-positive clinical staging. Moreover, the comparison between our policy and permanent histology of the sentinel node showed an 8% cost saving, mainly associated with the immediate axillary dissections. US-FNAC of axillary lymph nodes in breast cancer patients reliably predicts the presence of metastases and therefore refers a significant number of patients to the appropriate surgical treatment, avoiding an SNB. As cost saving to the health care system in our study is mainly related to one-step axillary surgery, US-FNAC of axillary lymph nodes and frozen section of the sentinel node generate significant cost saving for patients who have metastatic nodes.

Cabergoline (CAB), a new long-acting ergoline derivative, was shown to be very effective in reducing PRL levels in normal volunteers and in hyperprolactinemic patients. We evaluated the hormonal changes after discontinuation of long-term therapy with CAB as well as the safety of drug exposure during pregnancy both for mothers and babies. We therefore studied 48 patients (47 females and one male) with pathological hyperprolactinaemia (mean +/- SE, 117.2 +/- 15.2: median 73.2 micrograms/l), treated for 1-82 months (mean +/- SE, 28.3 +/- 3; median 18). After long-term treatment, CAB was withdrawn in 11 patients and PRL levels were persistently normal for almost 15 days and significantly lower (p < 0.05) than basal at 30, 45, 60, 90, 120 days. Three patients had normal PRL levels still at 45 days after treatment discontinuation. Nine patients became pregnant after 1-37 months (mean 12.4) of therapy. In two patients the pregnancy was interrupted spontaneously in one case and voluntarily in the other. In all but one patients after delivery or three-month breast feeding, PRL levels trended towards reduction. In two cases (one with microadenoma and one with idiopathic hyperprolactinaemia) PRL remained in the normal levels for 1-3 years after delivery. In conclusion CAB is able to inhibit plasma PRL levels for long time (up to 120 days) after withdrawal in patients with pathological hyperprolactinaemia treated with long-term therapy.

Objective: The aim of this study is to estimate the incidence of endometriosis in a northwestern region of Italy. The potential sources of geographical variations in the incidence of endometriosis within the region are discussed. Methods: The patients selected were women between 18 and 45 years of age, born and residing in Piedmont who had undergone medical or surgical treatment for endometriosis between 2000 and 2005. The data were obtained from official hospital discharge records. Results: The number of women contributed to the study was 3,929. The age-standardized incidence rate of endometriosis was 81.8/100,000 patient-years (95% CI 79.1–84.2). The distribution of relative risks showed some areas with an increased rate of around 30% (southern and central Piedmont), while for other areas the disease risk was lower (southwestern Piedmont). These areas have greater exposure to environmental risk due to the presence of chemical pollutants. Conclusion: In order to achieve reliable data and good management of the disease, there is great need for national registers, as well as networks of excellence for the treatment of endometriosis. Our findings suggest that environmental factors may be associated with the development of the disease, but the observed results need to be cautiously interpreted in the context of ineligible biases.
