Schauta-Amreich Operation vs Piver II Procedure with Pelvic Lymphadenectomy for Cervical Cancer.

INTRODUCTION: The aim of this study was to compare two groups of patients with early stage cervical cancer who underwent either abdominal or vaginal surgery, in terms of post-operative findings and survival. MATERIALS AND METHODOLOGY: 55 patients with diagnosed cervical cancer were retrospectively selected for this study. They were preoperatively staged according to FIGO criteria. Forty four patients had disease between stages Ib and IIa with no evidence of extra-pelvic lymph node involvement and 10 patients had stage ≥ IIb. RESULTS: Of the 55 patients, 17 had been operated by Schauta-Amreich radical vaginal hysterectomy and 38 by Piver type II abdominal hysterectomy. No significant statistical differences have been found between two groups about age (median age was 49 for Schauta and 54 for Piver p=0.494) and parity of the patients (Median parity was 2 (range: 0-5) for Piver II group and 1 (range: 0-4) for Schauta group (p=0.607)) and about histotype and stage of the cervical cancer (34 patients with squamous cell carcinoma among Piver II Group vs 16 patients from Schauta Group; 4 women with adenocarcinoma from Piver II Group vs 1 subject from the Schauta Group; p value 1.000). Among the two groups there were significant statistical differences regarding the mean operative time (86 ± 28 minutes for Vaginal surgery and 115 ± 31 minutes for Abdominal surgery, p=0.038) and the average hospital stay (8.65 ± 4.42 days for abdominal surgery and 5.65 ± 2.3 days for vaginal surgery, p=0.020). Significant statistical difference was reported as regarding adjuvant RT, increased in the Piver II group with respect to the Schauta group (22 vs 4 pts; p=0.028). The survival rate at 5-years was without significant difference between the two groups (23 patients frof Piver II Group vs 11 patients from Schauta Group, p=0.510). DISCUSSION: This study confirms the benefits of the Schauta-Amreich vaginal radical hysterectomy in terms of hospital stay, mean operative time and early complications. CONCLUSION: We believe that this surgery is a plausible alternative to radical abdominal hysterectomy and could be considered to be a valid approach for the treatment of patients with cervical neoplasms, but still randomized trials are needed on this topic with respect to the ethical issues involved.

Double inherited thrombophilias and adverse pregnancy outcomes: fashion or science?

AIM: To determine to what extent double inherited thrombophilias are associated with adverse obstetric complications correlated with fetoplacental insufficiency, such as preeclampsia, hemolytic anemia elevated liver enzymes and low platelet count (HELLP) syndrome, gestational hypertension, fetal growth restriction (FGR), intrauterine death (ID), abruptio placentae and disseminated intravascular coagulopathy. METHODS: Pregnant women coming to delivery were retrospectively divided into two groups: group A (controls) and group B (cases). Patients belonging to group B had one of the following: severe preeclampsia, HELLP syndrome, gestational hypertension, FGR, intrauterine death, abruptio placentae of disseminated intravascular coagulopathy. We detected methylenetetrahydrofolate reductase (MTHFR) A1298C, MTHFR C677T, factor V Leiden, PAI-1, mutant prothrombin G20210A, plasma homocysteine, antithrombin III, protein S and activated protein C resistance. Normal pregnant women or pregnant women with double defects were enrolled in this study. RESULTS: The combination of MTHFR C677T mutation with PAI-1 (5G/5G) mutation was significantly linked with the occurrence of ID. HELLP syndrome was significantly related to the simultaneous presence of factor VIII and X mutations. The combination of MTHFR C677T with factor VIII mutation and the combination of factor II and V mutations were significantly related to the occurrence of abruptio placentae. We found an association between double isoforms MTHFR mutation and FGR. CONCLUSION: It seems that some thrombophilias and a combination of thrombophilic factors carry a greater risk than others for a given adverse outcome. Further studies are needed to check the link between thrombophilic gene mutations and adverse pregnancy outcomes, such as recurrent miscarriages and deep venous thrombosis.

Ultrasound detection of the "sliding viscera" sign promotes safer laparoscopy.

STUDY OBJECTIVE: To estimate the feasibility of preoperative ultrasound evaluation of the umbilical region in patients undergoing laparoscopy with a previous history of abdominal surgery. DESIGN: Prospective study (Canadian Task Force Classification II-1). SETTING: Department of Obstetrics and Gynecology Fatebenefratelli Isola Tiberina Hospital. PATIENTS: Twenty-five women with a previous history of open abdominal surgery (group A) and a group of 22 women with no previous history of surgery (group B) underwent dynamic ultrasound evaluation of the umbilical field. INTERVENTION: Ultrasound Slide-By test. RESULTS: Patients were asked to take a deep inspiratory breath, which accentuated respiratory excursion. The movement of the intraabdominal contents in a vertical fashion in relation to the abdominal wall, referred to as the "viscera slide," between the bowel and peritoneum was evaluated. Abdominal wall tissue thickness, Uracus to peritoneum thickness (UTP, mm) were also evaluated. Non parametric Mann-Whitney testing was used. No major demographic differences between the 2 study groups was noted. The abdominal wall tissue thickness was not significantly different between the 2 groups. The UTP was shorter in A group than in B group (1.5 +/- 0.3 mm vs 3.5 +/- 0.9 mm, p = .002). Absence of the "sliding viscera" sign was observed in 16 patients in group A and in 1 patient in group B. Patients with an absence of the sliding viscera sign were found to have subumbilical fibrous adhesions during laparoscopy. CONCLUSIONS: Evaluation of trocar insertion sites may be difficult and remains a challenge for peritoneal endosurgical access. We have shown that absence of the "sliding viscera" sign is more likely to be linked to subumbilical adhesions and represents a quick method for preoperative assessment. The UTP may also be a useful measurement, which requires further validation.

Ultrasound-determined fetal subcutaneous tissue thickness for a birthweight prediction model.

AIM: The aim of this study was to explore a birthweight prediction model using ultrasound determined tissue thickness (SCTT) parameters. METHODS: We measured routine ultrasonographic biometric parameters and in addition, fetal SCTT in 201 healthy singleton pregnancies. Mid-arm fat and lean mass, mid-thigh fat and lean mass, subscapular fat mass and abdominal fat mass (AFM) were measured in order to calculate a birthweight prediction model. Ultrasound measurements were analyzed using an 'anovarepeated measures model'. The growth rate (beta-slope) of the selected parameters was computed and the correlation coefficient with the birthweight and the Kendall rank correlation tau, were calculated. RESULTS: From the ultrasound determined SCTT parameters, only abdominal circumference (AC), AFM, and MTLM showed a statistically significant trend. The beta-slope of mid-thigh lean mass was excluded since it exhibited significant correlation with the beta-slope of AFM. The final regression model could be calculated as: birthweight (gr.) = intercept +alpha(1)(AFM beta-slope) + alpha(2)(AC beta-slope), where alpha(1), alpha(2) represent regression coefficients. CONCLUSIONS: We provide a graphical birthweight prediction model for clinical practice using conventional and specific ultrasound measurements of fetal subcutaneous tissue thickness. This model is based upon an overall analysis of the ultrasound estimated body components.

Single inherited thrombophilias and adverse pregnancy outcomes.

INTRODUCTION: Inherited thrombophilia is believed to be a multiple gene disease with more than one defect. We aimed to determine the association between single thrombophilic patterns and a variety of pregnancy diseases. METHODS: 284 pregnant women were recruited for the present study and were divided in two groups: A group (176 controls) and B group (108 cases). Patients belonging to the B group had one of the following: severe pre-eclampsia, hemolysis, hepatic enzymes increase, hypertension and low platelet count (HELLP) syndrome, gestational hypertension, fetal growth restriction, intrauterine death, abruptio placentae and disseminated intravascular coagulopathy. To detect methylenetetrahydrofolate reductase (MTHFR) A1298C, MTHFR C677T, factor V Leiden, PAI-1, mutant prothrombin G20210A, an inverse hybridization technology was used. Plasma homocysteine, antithrombin (AT) III and protein S were determined. A modified functional activated protein C resistance was detected. RESULTS: MTHFR C677T and hyperhomocysteinemia were more prevalent than other thrombophilias. Deficiency in AT III was significantly linked with pre-eclampsia (relative risk 0.88; 95% CI 0.83-0.94). Activated protein C resistance (APCR) was significantly related to the abruptio placentae (relative risk 0.71; 95% CI 0.61-0.82). COMMENTS: Apart from the linkage between AT III deficiency and the occurrence of pre-eclampsia, and apart from the increased risk of abruptio placentae in pregnant women with altered APCR, we obtained findings in contrast with some of the published literature. In our case series, no association of pre-eclampsia with factor V Leiden or with prothrombin gene mutation was found.

Pelvic lymphadenectomy for cervical cancer: extraperitoneal versus laparoscopic approach.

OBJECTIVE: To compare the extraperitoneal versus the laparoscopic technique in performing pelvic lymphadenectomy in a series of patients undergoing a radical vaginal hysterectomy for locally advanced cervical cancer. STUDY DESIGN: Retrospective study with 42 patients undergoing a radical vaginal hysterectomy for cervical cancer. Patients from group A (20 patients) had a laparoscopic lymph node dissection and patients belonging to group B (22 patients) had an extraperitoneal lymphadenectomy. Historical data, clinical and surgical characteristics, perioperative and post-operative complications were analyzed. Follow-up was conducted according to the oncologic requirements. RESULTS: No significant difference was observed between the two groups in terms of blood loss, post-operative pain, transfusions, hospital stay and post-operative hematomas. The extraperitoneal group (group B) significantly showed a reduced operating time, a greater number of nodes removed (p<0.05). The only lymphocyst occurred in group B. CONCLUSIONS: Extraperitoneal pelvic lymphadenectomy can be considered an adequate technique to complement radical vaginal operations for cervical cancer.

Umbilical cord segmental hemorrhage and fetal distress.

We describe an unexplained case of umbilical cord segmental hemorrhage linked with meconium-stained amniotic fluid. A severely asphyxiated infant was delivered at term by Caesarean section. There were poor prognostic signs on fetal cardiotocography with rupture of membranes with meconium-stained amniotic fluid. The pathophysiologic mechanism in this case is still unknown, even if we argued a possible role of the umbilical cord shortness.

Homocysteinemia is inversely correlated with platelet count and directly correlated with sE- and sP-selectin levels in females homozygous for C677T methylenetetrahydrofolate reductase.

Plasma homocysteine levels depend in part on the molecular nature of the methylenetetrahydrofolate reductase (MTHFR) and on blood folate intake. Little has been reported on platelet counts in the presence of hyperhomocysteinemia and MTHFR polymorphisms, with the exception of delayed platelet recovery in homozygous MTHFR C677T subjects after treatment with methotrexate for ovarian cancer. The aim of this investigation was to evaluate the possibility of a link between the platelet count and plasma homocysteine levels in different MTHFR variants in 165 female patients. Determinations of plasma homocysteine levels were by ELISA and of MTHFR polymorphisms (A1298C and C677T) were by inverse hybridization. Serum P- and E-selectin concentrations were obtained by ELISA. An inverse correlation (R=-0.88, P<0.001) was observed between blood platelet counts and plasma homocysteine levels in the women homozygous for MTHFR C677T. This correlation did not depend on pregnancy or other variables reported. Serum concentrations of sE- and sP-selectin, markers of endothelial and platelet activation, were significantly and positively correlated with homocysteine levels. These findings suggest that homocysteine affects platelet numbers in women with MTHFR C677T possibly consequent to endothelial and platelet activation.
