Family planning, fertility awareness and knowledge about Italian legislation on assisted reproduction among Italian academic students.

Over the last century, most industrialized countries have experienced a progressive increase in maternal age at first pregnancy and a reduction of fertility rate, with important social and economic consequences. Moreover in Italy a very restrictive law on assisted reproductive technologies was introduced in 2004, limiting its effectiveness and causing a strong public debate that unfortunately focused more on the political and ethical implications of the law than on the medical and technical aspects of assisted reproduction. The present study performed an epidemiological investigation among the students of Turin University in the year 2006/07 in order to assess three aspects: the factors affecting the decision to become parents, their level of consciousness about human reproduction and their level of knowledge about the legal rules that regulate assisted reproduction in Italy. The study also wanted to clarify how the sex (male or female) and the type of education (sciences or humanities) could affect their opinions and knowledge in this area. It was observed that young people consider parenthood an important part of their life, but knowledge about human fertility and legal rules regulating assisted reproduction is rather poor, regardless of sex and type of education.

Slow-freezing-induced changes of birefringent structures in human oocytes are related to responsiveness to ovulation induction.

The slow-freezing method is widely used to freeze human oocytes, both for fertility preservation and in routine IVF programmes. Slow freezing damages some of the cell's structures, including the meiotic spindle (MS) and the zona pellucida (ZP). Polarized light microscopy was used to study the variations induced by slow freezing on the MS and the ZP of human oocytes and to analyse the relationship between slow-freezing effects on the gamete and some clinical characteristics, such as age, body mass index and ovarian responsiveness to ovulation induction (expressed as total follicle-stimulating hormone dose/retrieved oocyte). Both the MS and the ZP (particularly its inner layer) underwent significant changes during slow-freezing procedure. The MS became thinner and structurally less organized (lower retardance) (P<0.001 and P<0.05, respectively), whereas the ZP became thicker and its inner layer lost structural organization (both P<0.05). These morphological changes were unrelated to the patient's age or body mass index, but ZP variations in thickness and retardance were significantly related to ovarian responsiveness (P=0.033 and P=0.026, respectively), suggesting that patients with a higher response to gonadotrophins produce oocytes better able to preserve their characteristics after freezing-thawing.

Superfetation after ovulation induction and intrauterine insemination performed during an unknown ectopic pregnancy.

This report describes the first case of superfetation after ovarian stimulation with gonadotrophins and intrauterine insemination (IUI) that were performed in the presence of an undiagnosed tubal pregnancy. A 32-year-old woman who underwent repeated attempts of ovarian stimulation and IUI was hospitalized for severe pelvic pain and submitted to laparoscopic salpingectomy because of ruptured salpynx containing a 6-week pregnancy. Transvaginal ultrasound examination showed a simultaneous intrauterine 2-week pregnancy that had been conceived by ovarian stimulation and IUI while the tubal pregnancy was already ongoing and still undiagnosed. The intrauterine pregnancy went on until term and ended with the spontaneous delivery of a healthy baby. This report demonstrates that human superfetation may occur after gonadotrophin treatment and IUI in the presence of an ongoing tubal pregnancy. It is recommended to perform a pregnancy test before starting ovulation induction even when an apparently normal blood discharge appeared.

Epithelial-mesenchymal transition of ovarian tumor cells induces an angiogenic monocyte cell population.

Vasculogenesis, or recruitment of progenitors able to differentiate into endothelial-like cells, may provide an important contribution to neovessel formation in tumors. However, the factors involved in the vasculogenic process and in particular the role of the epithelial-mesenchymal transition of tumor cells have not yet been investigated. We found a CD14(+)/KDR(+) angiogenic monocyte population in undifferentiated ovarian tumors, significantly increased in the corresponding tumor metastasis. In vitro, monocyte differentiation into CD14(+)/KDR(+) cells was induced by conditioned media from the primary ovarian tumor cells expressing a mesenchymal phenotype. In contrast, the ovarian tumor cell line SKOV3 expressing an epithelial phenotype was unable to stimulate the differentiation of monocytes into CD14(+)/KDR(+) cells. When an epithelial-mesenchymal transition was induced in SKOV3, they acquired this differentiative ability. Moreover, after mesenchymal transition pleiotrophin expression by SKOV3 was increased and conversely its blockade significantly reduced monocyte differentiation. The obtained CD14(+)/KDR(+) cell population showed the expression of endothelial markers, increased the formation of capillary-like structures by endothelial cells and promoted the migration of ovarian tumor cells in vitro. In conclusion, we showed that the epithelial-mesenchymal transition of ovarian tumor cells induced differentiation of monocytes into the pro-angiogenic CD14(+)/KDR(+) population and thus it may provide a tumor microenvironment that favours vasculogenesis and metastatization of the ovarian cancer.

Follicular fluid content and oocyte quality: from single biochemical markers to metabolomics.

The assessment of oocyte quality in human in vitro fertilization (IVF) is getting increasing attention from embryologists. Oocyte selection and the identification of the best oocytes, in fact, would help to limit embryo overproduction and to improve the results of oocyte cryostorage programs. Follicular fluid (FF) is easily available during oocyte pick-up and theorically represents an optimal source on non-invasive biochemical predictors of oocyte quality. Unfortunately, however, the studies aiming to find a good molecular predictor of oocyte quality in FF were not able to identify substances that could be used as reliable markers of oocyte competence to fertilization, embryo development and pregnancy. In the last years, a well definite trend toward passing from the research of single molecular markers to more complex techniques that study all metabolites of FF has been observed. The metabolomic approach is a powerful tool to study biochemical predictors of oocyte quality in FF, but its application in this area is still at the beginning. This review provides an overview of the current knowledge about the biochemical predictors of oocyte quality in FF, describing both the results coming from studies on single biochemical markers and those deriving from the most recent studies of metabolomics.

A retrospective study on IVF outcome in euthyroid patients with anti-thyroid antibodies: effects of levothyroxine, acetyl-salicylic acid and prednisolone adjuvant treatments.

BACKGROUND: Anti-thyroid antibodies (ATA), even if not associated with thyroid dysfunction, are suspected to cause poorer outcome of in vitro fertilization (IVF). METHODS: We retrospectively analyzed: (a) the prevalence of ATA in euthyroid infertile women, (b) IVF outcome in euthyroid, ATA+ patients, and (c) the effect of adjuvant treatments (levothyroxine alone or associated with acetylsalicylic acid and prednisolone) on IVF results in ATA+ patients. One hundred twenty-nine euthyroid, ATA+ women undergoing IVF were compared with 200 matched, ATA-controls. During IVF cycle, 38 ATA+ patients did not take any adjuvant treatment, 55 received levothyroxin (LT), and 38 received LT +acetylsalicylic acid (ASA)+prednisolone (P). RESULTS: The prevalence of ATA among euthyroid, infertile patients was 10.5%, similar to the one reported in euthyroid women between 18 and 45 years. ATA+ patients who did not receive any adjuvant treatment showed significantly poorer ovarian responsiveness to stimulation and IVF results than controls. ATA+ patients receiving LT responded better to ovarian stimulation, but had IVF results as poor as untreated ATA+ women. Patients receiving LT+ASA+P had significantly higher pregnancy and implantation rates than untreated ATA+ patients (PR/ET 25.6% and IR 17.7% vs. PR/ET 7.5% and IR 4.7%, respectively), and overall IVF results comparable to patients without ATA (PR/ET 32.8% and IR 19%). CONCLUSION: These observations suggest that euthyroid ATA+ patients undergoing IVF could have better outcome if given LT+ASA+P as adjuvant treatment. This hypothesis must be verified in further randomized, prospective studies.

Ovarian hyper-stimulation syndrome after spontaneous conception.

Ovarian hyperstimulation syndrome (OHSS) is rather frequent (1-5%) in women submitted to superovulation with gonadotropins for in vitro fertilisation (IVF), whereas it is very rare in case of spontaneous ovulation. Spontaneous OHSS (sOHSS) was previously described to be associated to hydatiform mole, multiple conception, hypothyroidism in pregnancy. It may also depend on activating mutations of the FSH receptor (FSHR) gene that cause ovarian hyper-responsiveness to circulating FSH or even cross-responsiveness of FSHR to hormones having a structure similar to FSH, such as hCG or TSH. We report, herein, a case of sOHSS in a woman who conceived spontaneously. We checked the presence of all possible factors that could explain the onset of the syndrome, and we evidenced hypothyroidism and abnormally elevated hCG levels in the second trimester of pregnancy. The thorough molecular biology study of FSHR gene did not detect exonic mutations, but revealed the presence of intronic mutations whose role in the onset of sOHSS is still uncertain.

Guanylate cyclase activity and sperm function.

In species with external fertilization, the guanylate cyclase family is responsible for the long-distance interaction between gametes, as its activation allows sperm chemotaxis toward egg-derived substances, gamete encounter, and fertilization. In species with internal fertilization, guanylate cyclase-activating substances, which are secreted by several tissues in the genital tracts of both sexes, deeply affect sperm motility, capacitation, and acrosomal reactivity, stimulating sperm metabolism and promoting the ability of the sperm to approach the oocyte, interact with it, and finally fertilize it. A complex system of intracellular pathways is activated by guanylate cyclase agonists in spermatozoa. Sperm motility appears to be affected mainly through an increase in intracellular cAMP, whereas the acrosome reaction depends more directly on cyclic GMP synthesis. Both cyclic nucleotides activate specific kinases and ion signals. A complex cross-talk between cAMP- and cyclic GMP-generating systems occurs, resulting in an upward shift in sperm function. Excessive amounts of certain guanylate cyclase activators might exert opposite, antireproductive effects, increasing the oxidative stress on sperm membranes. In view of the marked influence exerted by guanylate cyclase-activating substances on sperm function, it seems likely that guanylate cyclase activation or inhibition may represent a new approach for the diagnosis and treatment of male and/or female infertility.

Integrative genomic analysis of protein kinase C (PKC) family identifies PKCiota as a biomarker and potential oncogene in ovarian carcinoma.

The protein kinase C (PKC) family plays a key regulatory role in a wide range of cellular functions as well as in various cancer-associated signal transduction pathways. Here, we investigated the genomic alteration and gene expression of most known PKC family members in human ovarian cancer. The DNA copy number of PKC family genes was screened by a high-resolution array-based comparative genomic hybridization in 89 human ovarian cancer specimens. Five PKC genes exhibited significant DNA copy number gains, including PKCiota (43.8%), PKCbeta1 (37.1%), PKCgamma (27.6%), PKCzeta (22.5%), and PKCtheta (21.3%). None of the PKC genes exhibited copy number loss. The mRNA expression level of PKC genes was analyzed by microarray retrieval approach. Two of the amplified PKC genes, PKCiota and PKCtheta, were significantly up-regulated in ovarian cancer compared with normal ovary. Increased PKCiota expression correlated with tumor stage or grade, and PKCiota overexpression was seen mostly in ovarian carcinoma but not in other solid tumors. The above results were further validated by real-time reverse transcription-PCR with 54 ovarian cancer specimens and 24 cell lines; overexpression of PKCiota protein was also confirmed by tissue array and Western blot. Interestingly, overexpressed PKCiota did not affect ovarian cancer cell proliferation or apoptosis in vitro. However, decreased PKCiota expression significantly reduced anchorage-independent growth of ovarian cancer cells, whereas overexpression of PKCiota contributed to murine ovarian surface epithelium transformation in cooperation with mutant Ras. We propose that PKCiota may serve as an oncogene and a biomarker of aggressive disease in human ovarian cancer.

Intratumoral T cells, recurrence, and survival in epithelial ovarian cancer.

BACKGROUND: Although tumor-infiltrating T cells have been documented in ovarian carcinoma, a clear association with clinical outcome has not been established. METHODS: We performed immunohistochemical analysis of 186 frozen specimens from advanced-stage ovarian carcinomas to assess the distribution of tumor-infiltrating T cells and conducted outcome analyses. Molecular analyses were performed in some tumors by real-time polymerase chain reaction. RESULTS: CD3+ tumor-infiltrating T cells were detected within tumor-cell islets (intratumoral T cells) in 102 of the 186 tumors (54.8 percent); they were undetectable in 72 tumors (38.7 percent); the remaining 12 tumors (6.5 percent) could not be evaluated. There were significant differences in the distributions of progression-free survival and overall survival according to the presence or absence of intratumoral T cells (P<0.001 for both comparisons). The five-year overall survival rate was 38.0 percent among patients whose tumors contained T cells and 4.5 percent among patients whose tumors contained no T cells in islets. Significant differences in the distributions of progression-free survival and overall survival according to the presence or absence of intratumoral T cells (P<0.001 for both comparisons) were also seen among 74 patients with a complete clinical response after debulking and platinum-based chemotherapy: the five-year overall survival rate was 73.9 percent among patients whose tumors contained T cells and 11.9 percent among patients whose tumors contained no T cells in islets. The presence of intratumoral T cells independently correlated with delayed recurrence or delayed death in multivariate analysis and was associated with increased expression of interferon-gamma, interleukin-2, and lymphocyte-attracting chemokines within the tumor. The absence of intratumoral T cells was associated with increased levels of vascular endothelial growth factor. CONCLUSIONS: The presence of intratumoral T cells correlates with improved clinical outcome in advanced ovarian carcinoma.

A prospective, randomised, controlled clinical study on the assessment of tolerability and of clinical efficacy of Merional (hMG-IBSA) administered subcutaneously versus Merional administered intramuscularly in women undergoing multifollicular ovarian stimulation in an ART programme (IVF).

BACKGROUND: Multifollicular ovarian stimulation (MOS) is widely used in IVF and the compliance to treatment is deeply influenced by the tolerability of the medication(s) used and by the ease of self-administration. This prospective, controlled, randomised, parallel group open label, multicenter, phase III, equivalence study has been aimed to compare the clinical effectiveness (in terms of oocytes obtained) and tolerability of subcutaneous (s.c.) self-administered versus classical intramuscular (i.m.) injections of Merional, a new highly-purified hMG preparation. METHODS: A total of 168 normogonadotropic women undergoing IVF were enrolled. Among them, 160 achieved pituitary suppression with a GnRH-agonist long protocol and were randomised to MOS treatment with Merional s.c. or i.m. They started MOS with a standard hMG dose between 150-300 IU, depending upon patient's age, and underwent a standard IVF procedure. RESULTS: No statistically significant difference in the mean number of collected oocytes (primary endpoint) was observed between the two study subgroups (7.46, SD 4.24 vs. 7.86, SD 4.28 in the s.c. and i.m. subgroups, respectively). As concerns the secondary outcomes, both the pregnancy and the clinical pregnancy rates were comparable between subgroups. The incidence of adverse events was similar in the two groups (2.4% vs. 3.7%, respectively). Pain at injection site was reported only the i.m. group (13.9% of patients). CONCLUSION: Merional may be used by s.c. injections in IVF with an effectiveness in terms of retrieved oocytes that is equivalent to the one obtained with i.m administration and with a better local tolerability. With the limitations due to the sample size af this study, s.c. and i.m. administration routes seem to have the same overall safety.

Impact of oncostatic treatments for childhood malignancies (radiotherapy and chemotherapy) on uterine competence to pregnancy.

UNLABELLED: Fertility preservation in young girls affected by malignancies has got growing relevance in the last decade due to the improved survival chance of these patients after oncostatic treatments. Most studies have focused on preserving ovarian follicles and avoiding premature ovarian failure, whereas only a few have evaluated the effects exerted by radiotherapy and chemotherapy on the uterus. It is self-evident that fertility preservation after oncostatic therapies must include the maintenance of a functional uterus, and a certain degree of uterine damage must be considered when estimating reproductive prognosis in previously treated, childhood cancer survivors. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to recall the growing number of children who survive oncostatic treatments, explain the possible effects on future reproductive endeavors, and summarize the possible ways to preserve fertility.

Ovarian tissue cryostorage and grafting: an option to preserve fertility in pediatric patients with malignancies.

Fertility preservation in childhood cancer has become an important area of investigation due to increasing survival rates after cancer therapy. For these patients with an increased risk of infertility and premature ovarian failure, cryopreservation of ovarian tissue is a promising tool to preserve at least part of the reproductive potential. In recent years significant improvements have been achieved in this area, and 2 live births after autografting of frozen-thawed ovarian tissue have been reported. However, further research is needed to assess the clinical effectiveness of ovarian cryopreservation, to optimize the technique, and to limit the risk of reintroducing cancer cells in the patient with the graft.

Recombinant versus highly-purified, urinary follicle-stimulating hormone (r-FSH vs. HP-uFSH) in ovulation induction: a prospective, randomized study with cost-minimization analysis.

BACKGROUND: Both recombinant FSH (r-FSH) and highly-purified, urinary FSH (HP-uFSH) are frequently used in ovulation induction associated with timed sexual intercourse. Their effectiveness is reported to be similar, and therefore the costs of treatment represent a major issue to be considered. Although several studies about costs in IVF have been published, data obtained in low-technology infertility treatments are still scarce. METHODS: Two hundred and sixty infertile women (184 with unexplained infertility, 76 with CC-resistant polycystic ovary syndrome) at their first treatment cycle were randomized and included in the study. Ovulation induction was accomplished by daily administration of rFSH or HP-uFSH according to a low-dose, step-up regimen aimed to obtain a monofollicular ovulation. A bi- or tri-follicular ovulation was anyway accepted, whereas hCG was withdrawn and the cycle cancelled when more than three follicles greater than or equal to 18 mm diameter were seen at ultrasound. The primary outcome measure was the cost of therapy per delivered baby, estimated according to a cost-minimization analysis. Secondary outcomes were the following: monofollicular ovulation rate, total FSH dose, cycle cancellation rate, length of the follicular phase, number of developing follicles (>12 mm diameter), endometrial thickness at hCG, incidence of twinning and ovarian hyperstimulation syndrome, delivery rate. RESULTS: The overall FSH dose needed to achieve ovulation was significantly lower with r-FSH, whereas all the other studied variables did not significantly differ with either treatments. However, a trend toward a higher delivery rate with r-FSH was observed in the whole group and also when results were considered subgrouping patients according to the indication to treatment. CONCLUSION: Considering the significantly lower number of vials/patient and the slight (although non-significant) increase in the delivery rate with r-FSH, the cost-minimization analysis showed a 9.4% reduction in the overall therapy cost per born baby in favor of r-FSH.

The serum concentration of human kallikrein 10 represents a novel biomarker for ovarian cancer diagnosis and prognosis.

Human kallikrein 10 (hK10) is a secreted serine protease that is highly expressed in ovarian tissue. We hypothesized that hK10 might represent a novel serological marker for ovarian cancer. We quantified by immunoassay, hK10 in sera from 97 normal women (controls), 141 patients with benign gynecologic diseases, and 146 patients with ovarian cancer. We then examined the diagnostic and prognostic value of this measurement in ovarian cancer. We found that normal serum hK10 ranged from 50 to 1040 ng/liter (mean = 439 ng/liter). hK10 concentration is significantly elevated in serum of presurgical ovarian cancer patients (range: 106-11,746 ng/liter; mean = 1067 ng/liter) but not in serum of patients with benign gynecologic diseases (range: 120-1200 ng/liter; mean = 447 ng/liter). When a cutoff of 700 ng/liter was selected (diagnostic specificity = 90%), the diagnostic sensitivity for ovarian cancer is 54%. About 35% of CA125-negative ovarian cancer patients (CA125 < 23 kU/liter) were hK10 positive at 90% specificity. In patients with stage I/II ovarian cancer, use of these two markers in combination results in a 21% increase in sensitivity, at 90% specificity, compared with CA125 alone. High serum hK10 was strongly associated with serous epithelial type, late-stage, advanced grade, large residual tumor (>1 cm), suboptimal debulking, and no response to chemotherapy (all Ps < 0.001). In univariate Cox survival analysis, high serum hK10 is associated with increased risk for relapse and death (hazard ratio = 2.59 and 3.15, respectively, P

Prognostic value of the human kallikrein gene 15 expression in ovarian cancer.

PURPOSE: KLK15 is a newly cloned human kallikrein gene. Many kallikreins were found to be differentially expressed in ovarian cancer. Like other kallikreins, KLK15 is regulated by steroid hormones in cancer cell lines. KLK15 is upregulated mainly by androgens and to a lesser extent by progestins. The purpose of this study was to examine the prognostic value of KLK15 in ovarian cancer tissues. MATERIALS AND METHODS: We studied KLK15 expression by quantitative reverse transcriptase polymerase chain reaction (RT-PCR) in 168 consecutive patients with epithelial ovarian cancer. Ten patients with benign ovarian tumors were also included in the study. An optimal cutoff point equal to the 50th percentile was defined based on the ability of KLK15 to predict progression-free survival and overall survival of the study population. RESULTS: KLK15 expression levels were significantly higher in cancerous tissues compared with benign tumors. Kaplan-Meier survival curves showed that KLK15 overexpression is a significant predictor of reduced progression-free survival (PFS; P <.001) and overall survival (OS; P <.009). Univariate and multivariate analyses indicate that KLK15 is an independent prognostic factor for PFS and OS. A weak positive correlation was found between KLK15 expression and serum CA-125 levels. CONCLUSION: KLK15 expression, as assessed by quantitative RT-PCR, is an independent marker of unfavorable prognosis for ovarian cancer.

Human kallikrein 6 (hK6): a new potential serum biomarker for diagnosis and prognosis of ovarian carcinoma.

PURPOSE: The discovery of new ovarian cancer biomarkers that are suitable for early disease diagnosis and prognosis may ultimately lead to improved patient management and outcomes. PATIENTS AND METHODS: We measured, by immunoassay, human kallikrein 6 (hK6) concentration in serum of 97 apparently healthy women, 141 women with benign abdominal diseases, and 146 women with histologically proven primary ovarian carcinoma. We then calculated the diagnostic sensitivity and specificity of this test and examined the association of serum hK6 concentration with various clinicopathologic variables and patient survival. RESULTS: Serum hK6 concentration between normal and benign disease patients was not different (mean, 2.9 and 3.1 micro g/L, respectively). However, hK6 in presurgical serum of ovarian cancer patients was highly elevated (mean, 6.8 micro g/L; P <.001). Serum hK6 decreased after surgery (to a mean of 3.9 micro g/L) in 68% of patients. The diagnostic sensitivity of serum hK6 at 90% and 95% specificity is 52% and 47%, respectively, in the whole patient population. For early stage disease (stage I or II), sensitivity is approximately 21% to 26%. When combined with CA-125, at 90% specificity, sensitivity increases to 72% (for all patients) and to 42% in stage I or II disease. Serum hK6 concentration correlates moderately with CA-125 and is higher in patients with late-stage, higher-grade disease and in patients with serous histotype. Preoperative serum hK6 concentration is a powerful predictor of disease-free and overall survival in both univariate and multivariate analyses. CONCLUSIONS: Serum hK6 concentration seems to be a new biomarker for ovarian carcinoma and may have value for disease diagnosis and prognosis.

Gestational hyperglycemia, zinc, selenium, and antioxidant vitamins.

OBJECTIVE: Lower levels of selenium and vitamin E have been described in gestational diabetes, a condition similar to type 2 diabetes, but few data are available about zinc (known to be associated with diabetes) and gestational hyperglycemia. This study evaluated the dietary intake of antioxidant vitamins, zinc, selenium, and serum levels of zinc and selenium in women with gestational hyperglycemia and normoglycemia. METHODS: A food-frequency questionnaire was administered to 504 pregnant women (210 with hyperglycemia and 294 with normoglycemia). Serum levels of zinc and selenium were analyzed during pregnancy in a second cohort of 71 hyperglycemic and 123 normoglycemic women, with a mean age and body mass index similar to those in the first cohort. RESULTS: Dietary intakes of zinc and selenium were significantly lower in hyperglycemic patients. In multiple logistic regression analysis, intakes were negatively associated with gestational hyperglycemia (odds ratios of 0.89 for zinc and 0.97 for selenium) after multiple adjustments. There were no significant differences in vitamin intakes. In the second cohort of 194 patients, serum levels of zinc and selenium were significantly lower in patients who had impaired glucose tolerance and negatively associated with gestational hyperglycemia in a multiple logistic regression model (odds ratios of 0.93 for serum zinc and 0.92 for serum selenium). CONCLUSIONS: Our data suggested a significant inverse association of dietary intakes and serum levels of zinc and selenium with gestational hyperglycemia. If future studies confirm these results, it might be a useful interventional approach to appropriate dietary counseling in order to evaluate the possible decrease in gestational metabolic abnormalities and their adverse consequences.

Single forearm radius and ulna asymmetric lengthening in multiple cartilaginous exostoses: a case report and a long-term follow-up.

We describe one case of forearm deformity in a patient affected by multiple cartilaginous exostoses - also known as the forearm 'candy stick deformity'. Surgical treatment usually focuses on the correction of the wrist deformity without correcting the forearm shortening, the latter not being given the same consideration as lower limb shortening. In the presented case, radius and ulna corticotomies were performed and distal forearm deformity and shortening were corrected by two independent monoaxial external fixators, with full pronosupination. It is our belief that simultaneous treatment of forearm shortening and deformity not only results in an improved clinical and functional result but also provides significant psychological benefit. We recommend a long-term follow-up.

Steroid hormone regulation and prognostic value of the human kallikrein gene 14 in ovarian cancer.

To study KLK14 gene expression in endocrine-related cancers, we studied its hormonal regulation in breast and ovarian cancer cell lines. Our kinetic and blocking experiments suggest that this up-regulation is mediated through the androgen receptor. We then studied the expression of KLK14 by quantitative reverse transcriptase-polymerase chain reaction in 155 consecutive ovarian tumors and correlated these findings with clinicopathologic parameters, response to chemotherapy, and survival. A stepwise reduction was observed in the levels of KLK14 messenger RNA in normal, benign, and cancerous tissues (P < .001). Expression levels were significantly higher in patients with early stage disease and optimal debulking and in patients who responded to chemotherapy. Kaplan-Meier survival curves demonstrated longer progression-free and overall survival in patients with KLK14-positive tumors than in patients with KLK14-negative tumors (P < .001). When all other prognostic variables were controlled in the multivariate analysis, KLK14 retained its prognostic significance (progression-free and overall survival, respectively, hazard ratios, 0.43 and 0.53; P = .027 and .014). A weak negative correlation was found between KLK14 expression and serum CA-125. KLK14 is a new, independent, and favorable prognostic marker for ovarian cancer.
