NT >99th centile and cystic hygroma: Which diagnosis, which management and outcome.

OBJECTIVES: To evaluate the prevalence of chromosomal anomalies in fetuses affected by increased nuchal translucency(iNT >99Th centile), cystic hygroma (CH) and cases progressing to fetal hydrops (NIHF) in order to correlate this result to prognosis and perinatal fetal outcomes, improving patient's counseling. METHODS: From January 2020 to December 2023, first trimester screening according to FMF criteria were performed in "Maternal fetal medicine Unit" of Foggia's hospital. We studied and collected clinical data of fetuses affected by nuchal translucency >99th centile (iNT), CH and cases progressing to Fetal Hydrops (non-immune fetal hydrop, NIFH). In these selected cases, we evaluated fetal Karyotype to demonstrate the presence of chromosomal abnormalities, associated to fetal structural anomalies and different pregnancy outcome. RESULTS: We have evaluated 45 cases of iNT, CH, and NIFH, identified by ultrasound during first trimester screening. Of these 45 pregnant women, four were lost to follow-up. Of the 41 pregnancies, 20 cases (48.8%) delivered at our division with newborns discharged in good health. Of the 21 patients (51.2%) who miscarried, only two miscarried spontaneously; the other 19 decided on a medical termination of pregnancy (MTP). The 19 patients who decided for MTP showed genetic abnormalities and/or malformation. The 20 cases of fetuses discharged as healthy newborns were enrolled with the following diagnoses: 5 had a diagnosis of CH (20% of cases), 1 case of NIFH (5% of cases), and 14 of iNT (75% of cases). All these fetuses had a normal karyotype and no major malformations. CONCLUSIONS: Isolated CH diagnosis is more frequent than described in Literature (5 cases out of 12: 41.7%) and their prognosis are better than previously described, with the same outcomes of fetuses with iNT without associated anomalies. The possibility of early diagnosis of chromosomal anomalies, associated malformations or the evolution into hydrops is essential for a complete consultation.

Outcome of fetuses with congenital cytomegalovirus infection and normal ultrasound at diagnosis: systematic review and meta-analysis.

OBJECTIVE: To report the outcome of fetuses with congenital cytomegalovirus (CMV) infection and normal ultrasound at the time of diagnosis, and to evaluate the rate of an additional anomaly detected only on magnetic resonance imaging (MRI). METHODS: Medline, EMBASE, CINAHL and Cochrane databases were searched for studies reporting on the outcome of fetuses with congenital CMV infection. Inclusion criteria were fetuses with confirmed CMV infection and normal ultrasound assessment at the time of the initial evaluation. The outcomes observed were an anomaly detected on a follow-up ultrasound scan, an anomaly detected on prenatal MRI but missed on ultrasound, an anomaly detected on postnatal assessment but missed prenatally, perinatal mortality, symptomatic infection at birth, neurodevelopmental outcome and hearing and visual deficits. Neurodevelopmental outcome was assessed only in cases of isolated CMV infection confirmed at birth. Subgroup analysis was performed according to the trimester in which maternal infection occurred. Random-effects meta-analysis of proportions was used to analyze the data. RESULTS: Twenty-six studies were included, comprising 2603 fetuses with congenital CMV infection, of which 1178 (45.3%) had normal ultrasound at the time of diagnosis and were included in the analysis. The overall rate of an associated central nervous system (CNS) anomaly detected on a follow-up ultrasound scan was 4.4% (95% CI, 1.4-8.8%) (32/523; 15 studies), while the rates of those detected exclusively on prenatal MRI or on postnatal imaging were 5.8% (95% CI, 1.9-11.5%) (19/357; 11 studies) and 3.2% (95% CI, 0.3-9.0%) (50/660; 17 studies), respectively. The rate of an associated extra-CNS anomaly detected on a follow-up ultrasound scan was 2.9% (95% CI, 0.8-6.3%) (19/523; 15 studies), while the rates of those detected exclusively on MRI or on postnatal imaging were 0% (95% CI, 0.0-1.7%) (0/357; 11 studies) and 0.9% (95% CI, 0.3-1.8%) (4/660; 17 studies), respectively. Intrauterine death and perinatal death each occurred in 0.7% (95% CI, 0.3-1.4%) (2/824; 23 studies) of cases. In cases without an associated anomaly detected pre- or postnatally, symptomatic infection was found in 1.5% (95% CI, 0.7-2.7%) (6/548; 19 studies) of infants, the overall rate of a neurodevelopmental anomaly was 3.1% (95% CI, 1.6-5.1%) (16/550; 19 studies), and hearing problems affected 6.5% (95% CI, 3.8-10.0%) (36/550; 19 studies) of children. Subanalyses according to the trimester in which maternal infection occurred were affected by the very small number of included cases and lack of comparison of the observed outcomes in the original studies. Compared with fetuses infected in the second or third trimester, those infected in the first trimester had a relatively higher risk of having an additional anomaly detected on follow-up ultrasound or MRI, abnormal neurodevelopmental outcome and hearing problems. CONCLUSIONS: In fetuses with congenital CMV infection in which no anomalies are detected on prenatal ultrasound or MRI, the risk of adverse postnatal outcome is lower than that reported previously in the published literature when not considering the role of antenatal imaging assessment. The results from this review also highlight the potential role of MRI, even in fetuses with no anomalies detected on ultrasound, as an anomaly can be detected exclusively on MRI in about 6% of cases. The findings from this study could enhance prenatal counseling of pregnancies with congenital CMV infection with normal prenatal imaging. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Outcome of twin-twin transfusion syndrome according to Quintero stage of disease: systematic review and meta-analysis.

OBJECTIVES: To report the outcome of pregnancies complicated by twin-twin transfusion syndrome (TTTS) according to Quintero stage. METHODS: MEDLINE, EMBASE and CINAHL databases were searched for studies reporting the outcome of pregnancies complicated by TTTS stratified according to Quintero stage (I-V). The primary outcome was fetal survival rate according to Quintero stage. Secondary outcomes were gestational age at birth, preterm birth (PTB) before 34, 32 and 28 weeks' gestation and neonatal morbidity. Outcomes are reported according to the different management options (expectant management, laser therapy or amnioreduction) for pregnancies with Stage-I TTTS. Only cases treated with laser therapy were considered for those with Stages-II-IV TTTS and only cases managed expectantly were considered for those with Stage-V TTTS. Random-effects head-to-head meta-analysis was used to analyze the extracted data. RESULTS: Twenty-six studies (2699 twin pregnancies) were included. Overall, 610 (22.6%) pregnancies were diagnosed with Quintero stage-I TTTS, 692 (25.6%) were Stage II, 1146 (42.5%) were Stage III, 247 (9.2%) were Stage IV and four (0.1%) were Stage V. Survival of at least one twin occurred in 86.9% (95% CI, 84.0-89.7%) (456/552) of pregnancies with Stage-I, in 85% (95% CI, 79.1-90.1%) (514/590) of those with Stage-II, in 81.5% (95% CI, 76.6-86.0%) (875/1040) of those with Stage-III, in 82.8% (95% CI, 73.6-90.4%) (172/205) of those with Stage-IV and in 54.6% (95% CI, 24.8-82.6%) (5/9) of those with Stage-V TTTS. The rate of a pregnancy with no survivor was 11.8% (95% CI, 8.4-15.8%) (69/564) in those with Stage-I, 15.0% (95% CI, 9.9-20.9%) (76/590) in those with Stage-II, 18.6% (95% CI, 14.2-23.4%) (165/1040) in those with Stage-III, 17.2% (95% CI, 9.6-26.4%) (33/205) in those with Stage-IV and in 45.4% (95% CI, 17.4-75.2%) (4/9) in those with Stage-V TTTS. Gestational age at birth was similar in pregnancies with Stages-I-III TTTS, and gradually decreased in those with Stages-IV and -V TTTS. Overall, the incidence of PTB and neonatal morbidity increased as the severity of TTTS increased, but data on these two outcomes were limited by the small sample size of the included studies. When stratifying the analysis of pregnancies with Stage-I TTTS according to the type of intervention, the rate of fetal survival of at least one twin was 84.9% (95% CI, 70.4-95.1%) (94/112) in cases managed expectantly, 86.7% (95% CI, 82.6-90.4%) (249/285) in those undergoing laser therapy and 92.2% (95% CI, 84.2-97.6%) (56/60) in those after amnioreduction, while the rate of double survival was 67.9% (95% CI, 57.0-77.9%) (73/108), 69.7% (95% CI, 61.6-77.1%) (203/285) and 80.8% (95% CI, 62.0-94.2%) (49/60), respectively. CONCLUSIONS: Overall survival in monochorionic diamniotic pregnancies affected by TTTS is higher for earlier Quintero stages (I and II), but fetal survival rates are moderately high even in those with Stage-III or -IV TTTS when treated with laser therapy. Gestational age at birth was similar in pregnancies with Stages-I-III TTTS, and gradually decreased in those with Stages-IV and -V TTTS treated with laser and expectant management, respectively. In pregnancies affected by Stage-I TTTS, amnioreduction was associated with slightly higher survival compared with laser therapy and expectant management, although these findings may be confirmed only by future head-to-head randomized trials.

Resultado del síndrome de transfusión feto-fetal según el estadio de Quintero de la enfermedad: revisión sistemática y metaanálisis OBJETIVOS: Informar sobre el resultado de los embarazos complicados por el síndrome de transfusión feto-fetal (TTTS, por sus siglas en inglés) según el estadio de Quintero. MÉTODOS: Se hicieron búsquedas en las bases de datos de MEDLINE, EMBASE y CINAHL de estudios que hubieran informado sobre el resultado de embarazos complicados por TTTS, estratificados según el estadio de Quintero (I-V). El resultado primario fue la tasa de supervivencia fetal según el estadio de Quintero. Los resultados secundarios fueron la edad gestacional al nacer, el parto pretérmino (PPT) antes de las 34, 32 y 28 semanas de gestación y la morbilidad neonatal. Los resultados se reportan de acuerdo con las diferentes opciones de tratamiento (expectante, terapia de láser o amniorreducción) para los embarazos con TTTS en Estadio I. Sólo se consideraron los casos tratados con terapia de láser para aquellos con TTTS de las Etapas II-IV y sólo se consideraron los casos tratados de manera expectante para aquellos con TTTS de la Etapa V. Para analizar los datos extraídos se utilizó un metaanálisis directo de efectos aleatorios. RESULTADOS: Se incluyeron veintiséis estudios (2699 embarazos de gemelos). En total, 610 (22,6%) embarazos fueron diagnosticados con TTTS de Estadio I de Quintero, 692 (25,6%) de Estadio II, 1146 (42,5%) de Estadio III, 247 (9,2%) de Estadio IV y cuatro (0,1%) de Estadio V. La supervivencia de al menos un gemelo se produjo en el 86,9% (IC 95%, 84,0-89,7%) (456/552) de los embarazos en Estadio I, en el 85% (IC 95%, 79,1-90,1%) (514/590) de aquellos en Estadio II, en el 81,5% (IC 95%, 76,6-86,0%) (875/1040) de aquellos en Estadio-III, en el 82,8% (IC 95%, 73,6-90,4%) (172/205) de aquellos en Estadio-IV y en el 54,6% (IC 95%, 24,8-82,6%) (5/9) de aquellos en Estadio-V de TTTS. La tasa de embarazos sin supervivientes fue del 11,8% (IC 95%, 8,4-15,8%) (69/564) de aquellos en Estadio-I, 15,0% (IC 95%, 9,9-20,9%) (76/590) de aquellos en Estadio-II, 18,6% (IC 95%, 14,2-23,4%) (165/1040) de aquellos en Estadio-III, 17,2% (IC 95%, 9,6-26,4%) (33/205) de aquellos en Estadio-IV y en el 45,4% (IC 95%, 17,4-75,2%) (4/9) de aquellos en Estadio-V de TTTS. La edad gestacional al nacer fue similar en los embarazos con TTTS en los Estadios I-III, y disminuyó gradualmente en aquellos con TTTS en los Estadios IV y V. En general, la incidencia de PPT y la morbilidad neonatal aumentaron a medida que se incrementó la gravedad del TTTS, pero los datos sobre estos dos resultados se vieron limitados por el pequeño tamaño de la muestra de los estudios incluidos. Al estratificar el análisis de los embarazos con TTTS en Estadio I según el tipo de tratamiento, la tasa de supervivencia fetal de al menos un gemelo fue del 84,9% (IC 95%, 70,4-95,1%) (94/112) en los casos tratados de forma expectante, del 86,7% (IC 95%, 82,6-90.4%) (249/285) en los sometidos a terapia láser y del 92,2% (IC 95%, 84,2-97,6%) (56/60) en los sometidos a amniorreducción, mientras que la tasa de supervivencia doble fue del 67,9% (IC 95%, 57,0-77,9%) (73/108), del 69,7% (IC 95%, 61,6-77,1%) (203/285) y del 80,8% (IC 95%, 62,0-94,2%) (49/60), respectivamente. CONCLUSIONES: La supervivencia en general en los embarazos biamnióticos monocoriónicos afectados por TTTS es mayor en los estadios tempranos de Quintero (I y II), pero las tasas de supervivencia fetal son moderadamente altas incluso en aquellos con TTTS en estadios III o IV cuando se tratan con terapia láser. La edad gestacional al nacer fue similar en los embarazos con TTTS en los Estadios I-III, y disminuyó gradualmente en aquellos con TTTS en los Estadios IV y V tratados con láser y tratamiento expectante, respectivamente. En los embarazos afectados por TTTS en Estadio I, la amniorreducción estuvo asociada con una supervivencia ligeramente mayor en comparación con la terapia de láser y el tratamiento expectante, aunque estos hallazgos solo pueden confirmarse mediante futuros estudios aleatorizados directos.

Outcome of twin-to-twin transfusion syndrome in monochorionic monoamniotic twin pregnancy: systematic review and meta-analysis.

OBJECTIVES: To explore the outcome of monochorionic monoamniotic (MCMA) twin pregnancies affected by twin-to-twin transfusion syndrome (TTTS). METHODS: MEDLINE and EMBASE databases were searched for studies reporting the outcome of MCMA twin pregnancies complicated by TTTS. The primary outcome was intrauterine death (IUD); secondary outcomes were miscarriage, single IUD, double IUD, neonatal death (NND), perinatal death (PND), survival of at least one twin, survival of both twins and preterm birth (PTB) before 32 weeks' gestation. Outcomes were assessed in MCMA twins affected by TTTS not undergoing intervention and in those treated with amniodrainage, laser therapy or cord occlusion. Subgroup analysis was performed including cases diagnosed before 24 weeks. Random-effects meta-analysis of proportions was used to analyze the data. RESULTS: Fifteen cohort studies, including 888 MCMA twin pregnancies, of which 44 were affected by TTTS, were included in the review. There was no randomized trial comparing the different management options in MCMA twin pregnancies complicated by TTTS. In cases not undergoing intervention, miscarriage occurred in 11.0% of fetuses, while the incidence of IUD, NND and PND was 25.2%, 12.2% and 31.2%, respectively. PTB complicated 50.5% of these pregnancies. In cases treated by laser surgery, the incidence of miscarriage, IUD, NND and PND was 19.6%, 27.4%, 7.4% and 35.9%, respectively, and the incidence of PTB before 32 weeks' gestation was 64.9%. In cases treated with amniodrainage, the incidence of IUD, NND and PND was 31.3%, 13.5% and 45.7% respectively, and PTB complicated 76.2% of these pregnancies. Analysis of cases undergoing cord occlusion was affected by the very small number of included cases. Miscarriage occurred in 19.2%, while there was no case of IUD or NND of the surviving twin. PTB before 32 weeks occurred in 50.0% of these cases. CONCLUSIONS: MCMA twin pregnancies complicated by TTTS are at high risk of perinatal mortality and PTB. Further studies are needed in order to elucidate the optimal type of prenatal treatment in these pregnancies. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Three-dimensional echocardiographic evaluation of the right ventricle in patients with uncomplicated systemic lupus erythematosus.

Our aim was to identify subclinical right ventricular (RV) alterations in systemic lupus erythematosus (SLE) by combining standard and three-dimensional echocardiography (3DE). Fifty SLE patients without concomitant cardiac disease and 50 healthy controls, matched for age and gender, were enrolled. Disease damage was evaluated by inflammatory markers and SLE damage index. All patients underwent an echo-Doppler examination with 3DE assessment of RV function, RV septal and lateral longitudinal strain. The two groups had comparable body mass index and blood pressure. RV transversal middle diameter and pulmonary arterial pressure were significantly higher in SLE compared to controls. By 3DE, RV end-systolic volume ( p = 0.037) was greater, whereas stroke volume ( p = 0.023), ejection fraction ( p < 0.0001) and septal and lateral longitudinal strain (both p < 0.0001) were lower in SLE. SLE damage index ≥ 1 was negatively associated with tricuspid annular plane systolic excursion (TAPSE) ( p < 0.002), tricuspid E/A ratio ( p = 0.003), RV ejection fraction ( p < 0.05), lateral longitudinal strain ( p < 0.0001) and septal longitudinal strain ( p = 0.04). By separate multivariate models, after adjusting for age, C reactive protein and proBNP, SLE damage index was independently associated with TAPSE ( p = 0.009) and RV lateral longitudinal strain ( p = 0.007). In conclusion, a subclinical RV systolic dysfunction is detectable in SLE by 3DE, RV lateral wall strain being a key parameter. RV dysfunction is associated with cumulative disease damage.

Management of bladder endometriosis with combined transurethral and laparoscopic approach. Follow-up of pain control, quality of life, and sexual function at 12 months after surgery.

To describe the pre-surgical and post-surgical outcomes at one year in terms of recurrence of lower urinary tract symptoms, quality of life, and sexual function of a transurethral and laparoscopic combined approach in the treatment of bladder endometriosis. The au- thors performed a prospective observational study of 16 women affected by symptomatic bladder endometriosis at the University Hos- pitals of Cagliari, Padua, and Foggia. In all patients bladder nodule was excised with a transurethral and laparoscopic combined approach technique. Intensity of lower urinary tract symptoms (VAS score) were assessed pre- and post-operatively at one, six, and 12 months after surgery; quality of life (SF-36) and sexual functions (FSFI) were collected preoperatively and one year postoperatively. Operative time was 120.18 ± 15.77 minutes and mean blood loss was 65.12 ± 44.74. No intraoperative and postoperative complications and conversion laparotomy occurred. Intensity of lower urinary tract symptoms evaluated with VAS score were significantly lower after one, six, and 12 months postsurgery vs. presurgery (p < 0.001). The authors observed a significantly improvement in the quality of life and sexual functions in all patients at one year after surgery. This surgical approach is safe and simple in the treatment of bladder en- dometriosis, with low risks and optimal resolution of symptoms, and improvement of quality of life and sexual function.

Bilateral salpingo-oophorectomy and adhesiolysis with single port access laparoscopy and use of diode laser in a BRCA carrier.

Herein the authors report the first case of prophylactic bilateral salpingo-ovariectomy (BSO) in single port access laparoscopy (SPAL) with use of diode laser in a patient with BRCA1 mutation. As fimbria could be considered the site of origin for many serous carcinomas in BRCA mutation carriers, many studies are carried out to evaluate the possibility of preventing ovarian carcinoma with BSO. SPAL is a development of endoscopic surgery which further reduces invasiveness of surgical procedures. Diode laser presents a recognized precision for tissue cutting and coagulation and its use could be highly advantageous in SPAL surgery and in particular in such situations avoiding fallopian tube histology distortion and consequently improve the prognosis of BRCA carriers.

The dual PI3K/mTOR inhibitor PKI-587 enhances sensitivity to cetuximab in EGFR-resistant human head and neck cancer models.

BACKGROUND: Cetuximab is the only targeted agent approved for the treatment of head and neck squamous cell carcinomas (HNSCC), but low response rates and disease progression are frequently reported. As the phosphoinositide 3-kinase (PI3K) and the mammalian target of rapamycin (mTOR) pathways have an important role in the pathogenesis of HNSCC, we investigated their involvement in cetuximab resistance. METHODS: Different human squamous cancer cell lines sensitive or resistant to cetuximab were tested for the dual PI3K/mTOR inhibitor PF-05212384 (PKI-587), alone and in combination, both in vitro and in vivo. RESULTS: Treatment with PKI-587 enhances sensitivity to cetuximab in vitro, even in the condition of epidermal growth factor receptor (EGFR) resistance. The combination of the two drugs inhibits cells survival, impairs the activation of signalling pathways and induces apoptosis. Interestingly, although significant inhibition of proliferation is observed in all cell lines treated with PKI-587 in combination with cetuximab, activation of apoptosis is evident in sensitive but not in resistant cell lines, in which autophagy is pre-eminent. In nude mice xenografted with resistant Kyse30 cells, the combined treatment significantly reduces tumour growth and prolongs mice survival. CONCLUSIONS: Phosphoinositide 3-kinase/mammalian target of rapamycin inhibition has an important role in the rescue of cetuximab resistance. Different mechanisms of cell death are induced by combined treatment depending on basal anti-EGFR responsiveness.

Inhibition of Hedgehog signalling by NVP-LDE225 (Erismodegib) interferes with growth and invasion of human renal cell carcinoma cells.

BACKGROUND: Multiple lines of evidence support that the Hedgehog (Hh) signalling has a role in the maintenance and progression of different human cancers. Therefore, inhibition of the Hh pathway represents a valid anticancer therapeutic approach for renal cell carcinoma (RCC) patients. NVP-LDE225 is a Smoothened (Smo) antagonist that induces dose-related inhibition of Hh and Smo-dependent tumour growth. METHODS: We assayed the effects of NVP-LDE225 alone or in combination with everolimus or sunitinib on the growth and invasion of human RCC models both in vitro and in vivo. To this aim, we used a panel of human RCC models, comprising cells with acquired resistance to sunitinib - a multiple tyrosine kinase inhibitor approved as a first-line treatment for RCC. RESULTS: NVP-LDE225 cooperated with either everolimus or sunitinib to inhibit proliferation, migration, and invasion of RCC cells even in sunitinib-resistant (SuR) cells. Some major transducers involved in tumour cell motility, including paxillin, were also efficiently inhibited by the combination therapy, as demonstrated by western blot and confocal microscopy assays. Moreover, these combined treatments inhibited tumour growth and increased animal survival in nude mice xenografted with SuR RCC cells. Finally, lung micrometastasis formation was reduced when mice were treated with NVP-LDE225 plus everolimus or sunitinib, as evidenced by artificial metastatic assays. CONCLUSIONS: Hedgehog inhibition by NVP-LDE225 plus sunitinib or everolimus bolsters antitumour activity by interfering with tumour growth and metastatic spread, even in SuR cells. Thus, this new evidence puts forward a new promising therapeutic approach for RCC patients.

Accuracy of hysteroscopy made by young residents in detecting endometrial pathologies in postmenopausal women.

PURPOSE OF INVESTIGATION: The aim of the study was to analyze the diagnostic value of hysteroscopy made by young residents in evaluating uterine cavity compared to experienced hysteroscopists with histological diagnosis as reference in postmenopausal women, with particular attention to endometrial hyperplasia and cancer. MATERIALS AND METHODS: A total of 600 postmenopausal women that underwent diagnostic hysteroscopy (DH) between January 2011 and December 2013 were evaluated. The authors compared the first 200 hysteroscopic findings of each young resident with those of seniors that supervised all the procedures, regarding the same patients. Subsequent histological evaluation was obtained by operative hysteroscopy or endometrial biopsy. Residents' and seniors' data were compared with the final histological diagnosis established by anatomopathologist. RESULTS: No adverse effects such as vaso-vagal reactions or uterine perforations in DH neither in operative hysteroscopic procedures were reported. Hysteroscopy made by residents had 60%, 9.09%, and 70.4% sensitivity (SE) and 97.1%, 98.8%, and 99.1% specificity (SP) in detecting hyperplasia without atypia, hyperplasia with atypia, and endometrial cancer, respectively. On the other hand, DH made by seniors resulted in 85%, 72.7%, and 96.3% SE and 99.8%, 99.8%, and 100% SP, in detecting the same three histological findings. CONCLUSION: Outpatient hysteroscopy made by residents at their endoscopic experience beginning has good accuracy in detecting clear endometrial malignant lesions, unlike in detecting premalignant lesion as hyperplasia with atypia. This could signify that more than 200 hysteroscopies are necessary for a resident to well recognize premalignant and malignant lesions.

Uterine leiomyosarcoma: report of three cases and review of the literature.

This is the report of three cases of unsuspected uterine leiomyosarcoma diagnosed by pathologist after hysteroscopic resection. The literature on this issue has been reviewed. Mesenchymal uterine tumors are rare malignancies, occurring in only 17 per one million women annually. The three most common variants of uterine sarcoma are endometrial stromal sarcoma, leiomyosarcoma, and malignant mixed Müllerian tumour. Less than one percent of women believed to have a leiomyoma actually have a sarcoma at hysterectomy. According to the authors' experience and the available literature reviewed, the removal of the whole myomatosus lesion, even if its appearance suggests a typical submucosal myoma, represents the only method to definitively rule out the presence of sarcomatous tissue.

Angiogenic and signalling proteins correlate with sensitivity to sequential treatment in renal cell cancer.

BACKGROUND: We aimed to study key signalling proteins involved in angiogenesis and proliferation on the response to inhibitors of tyrosine kinases and mammalian target of rapamycin in first- and in second-line treatment of renal cell carcinoma (RCC). METHODS: In a panel of human RCC tumours, in vitro and in nude mice, we evaluated the effect of sunitinib, sorafenib and everolimus, alone and in sequence, on tumour growth and expression of signalling proteins involved in proliferation and resistance to treatment. RESULTS: We demonstrated that, as single agents, sunitinib, sorafenib and everolimus share similar activity in inhibiting cell proliferation, signal transduction and vascular endothelial growth factor (VEGF) secretion in different RCC models, both in vitro and in tumour xenografts. Pre-treatment with sunitinib reduced the response to subsequent sunitinib and sorafenib but not to everolimus. Inability by sunitinib to persistently inhibit HIF-1, VEGF and pMAPK anticipated treatment resistance in xenografted tumours. After first-line sunitinib, second-line treatment with everolimus was more effective than either sorafenib or rechallenge with sunitinib in interfering with signalling proteins, VEGF and interleukin-8, translating into a significant advantage in tumour growth inhibition and mice survival. CONCLUSION: We demonstrated that a panel of angiogenic and signalling proteins can correlate with the onset of resistance to sunitinib and the activity of everolimus in second line.

Toll-like receptor 9 agonist IMO cooperates with everolimus in renal cell carcinoma by interfering with tumour growth and angiogenesis.

BACKGROUND: Targeting the mammalian target of rapamycin by everolimus is a successful approach for renal cell carcinoma (RCC) therapy. The Toll-like receptor 9 agonist immune modulatory oligonucleotide (IMO) exhibits direct antitumour and antiangiogenic activity and cooperates with both epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) inhibitors. METHODS: We tested the combination of IMO and everolimus on models of human RCC with different Von-Hippel Lindau (VHL) gene status, both in vitro and in nude mice. We studied their direct antiangiogenic effects on human umbilical vein endothelial cells. RESULTS: Both IMO and everolimus inhibited in vitro growth and survival of RCC cell lines, and their combination produced a synergistic inhibitory effect. Moreover, everolimus plus IMO interfered with EGFR-dependent signaling and reduced VEGF secretion in both VHL wild-type and mutant cells. In RCC tumour xenografts, IMO plus everolimus caused a potent and long-lasting cooperative antitumour activity, with reduction of tumour growth, prolongation of mice survival and inhibition of signal transduction. Furthermore, IMO and everolimus impaired the main endothelial cell functions. CONCLUSION: A combined treatment with everolimus and IMO is effective in VHL wild-type and mutant models of RCC by interfering with tumour growth and angiogenesis, thus representing a potentially effective, rationale-based combination to be translated in the clinical setting.

Laparoscopic surgical staging of endometrial cancer: does obesity influence feasibility and perioperative outcome?

AIM: Laparoscopic treatment of early-stage endometrial cancer is the gold standard to reduce perioperative morbidity. Obesity is a well-known risk factor for endometrial cancer and anesthesiological and surgical complications. The authors' aim was to examine the effect of body mass index (BMI) on perioperative parameters and complications in laparoscopically-treated patients with endometrial cancer. MATERIALS AND METHODS: A consecutive series of patients affected by endometrial cancer and their demographic and clinicopathological data were collected. Patients were divided in 41 non-obese (BMI or= 30) groups. All patients had been preoperatively evaluated with hysteroscopic procedures and toraco-abdominal computed tomography (CT) and had been submitted to laparoscopic radical hysterectomy according to Querleu-Morrow, pelvic lymphadenectomy, peritoneal washing, and bilateral adnexectomy. RESULTS: There was no statistically significant difference in blood loss, number of lymph nodes removed, and hospital stay between the groups, but there was a trend towards a lengthening of surgical time in the obese women. There were no major intraoperative and postoperative complications. DISCUSSION: This study demonstrates that laparoscopic approach is feasible and safe in obese women evaluating the anesthesiological risk.

Paraneoplastic sensitive neuropathy associated with anti-hu antibodies in a neuroendocrine tumor of duodenum: a case report.

Paraneoplastic sensitive neuropathy is one of the most common presentations among a group of cancer-related disorders known as Paraneoplastic Neurological Syndromes (PNS). PNS likely have an autoimmune etiology since they have been associated with the presence of antibodies against neuronal antigens expressed by tumor cells (such as anti-Hu, anti-Ri and anti-Yo). The tumors most frequently associated with PSN and onconeural antibodies are lung cancer, lymphomas and gynaecological tumors; however, they have also been described in other tumors. We report, for the first time, a case of neuroendocrine tumor of duodenum and PNS associated with anti-Hu antibodies. Moreover, we analyze and discuss the clinical implications that PNS and anti-Hu could have in patients with tumors.

Pathophysiology of hypoxic-ischemic encephalopathy: a review of the past and a view on the future.

Hypoxic-ischemic encephalopathy, also referred as HIE, is a type of brain injury or damage that is caused by a lack of oxygen to the brain during neonatal period. The incidence is approximately 1.5 cases per 1000 live births in developed countries. In low and middle-income countries, the incidence is much higher (10‒20 per 1000 live births). The treatment for neonatal HIE is hypothermia that is only partially effective (not more than 50% of the neonates treated achieve an improved outcome). HIE pathophysiology involves oxidative stress, mitochondrial energy production failure, glutaminergic excitotoxicity, and apoptosis. So, in the last years, many studies have focused on peptides that act somewhere in the pathway activated by severe anoxic injury leading to HIE. This review describes the pathophysiology of perinatal HIE and the mechanisms that could be the target of innovative HIE treatments.

Usefulness of symphysis-fundal height in predicting fetal weight in healthy term pregnant women.

BACKGROUND: There are some works reporting that the measurement of the symphysis-fundal height (SFH) of a full-term uterus is a simple method for estimating the fetal weight. AIM: Evaluating the goodness of distance between the symphysis and uterine fundus in predicting both low-weight fetuses and high-weight fetuses, comparing it with the third quarter ultrasound estimation of fetal weight and then assessing the clinical effectivity of symphysis-fundal measurement associated with third quarter echography in predicting birth weight. METHODS: A prospective study was carried out on 96 single physiologically full-term pregnancies. The diagnostic accuracy of the SFH, echographic fetal growth estimated between the 32nd and the 35th week (expressed in percentiles), and of both was expressed as sensitivity, specificity, predictive positive and negative value, likelihood ratios and compared. RESULTS: There was a correlation between the SFH and fetal birth weight. A SFH below 33 cm is predictive of a fetus whose weight is less than 3,100 g whereas a SFH above 34 cm is predictive of a fetus whose weight is more than or equal to 4,000 g. The diagnostic effectiveness of the SFH was not significantly higher than the ultrasound scanning evaluation of fetal weight in the third quarter and could be slightly improved if it is taken into account along with the ultrasound scanning data. CONCLUSIONS: The measurement of the SFH at term may be helpful in foretelling the fetal birth weight and may improve the diagnostic accuracy of the third quarter echographic estimation of birth weight.
