Predictive value of hyperglycosylated human chorionic gonadotropin for pregnancy outcomes in threatened abortion in first-trimester viable pregnancies

BACKGROUND

To investigate the value of a single determination of hyperglycosylated hCG (hCG-H) for predicting the clinical outcome of patients with threatened abortion in the first trimester of pregnancy.

METHODS

Prospective study performed on 86 consecutively selected women with a diagnosis of threatened abortion and viable intrauterine pregnancy in the first trimester of pregnancy, conducted in two tertiary care hospitals. All patients underwent a single blood sample to determine hCG-H and total hCG serum levels and a transvaginal ultrasound 12-24 hours after diagnosis. Patients were monitored to determine whether the outcome was a miscarriage before the 20th week of pregnancy.

RESULTS

Forty-three women (50%) had a miscarriage during the follow-up. We observed a very high correlation between hCG-H and total hCG (r?=?0.91, p?<?0.001). Median hCG-H and total hCG from pregnancies with normal outcome was signif-icantly higher than those ending in abortion. hCG-H and total hCG were very similar predictors of pregnancy outcomes (AUC: 0.90 and 0.89, respectively). The ratio hCG-H / total hCG was a poor predictor (AUC: 0.64).

CONCLUSION

A single hCG-H assay is helpful for predicting pregnancy outcomes in women with first trimester threatened abortion and viable or potentially viable pregnancy at the time of presentation. However, hCG-H is not a better predictor than total hCG.

Indications and practice of diverting ileostomy after colorectal resection and anastomosis in ovarian cancer cytoreduction

OBJECTIVE

To determine the factors related with diverting ileostomy performance after colorectal resection and anastomosis, in advanced ovarian cancer cytoreductive surgery.

METHODS

We have previously demonstrated the risk factors associated with anastomotic leak after colorectal anastomosis: Advanced age at surgery, low serum albumin level, additional bowel resections, manual anastomosis and distance of the anastomosis from the anal verge. However, use of diverting ileostomy is strongly variable and depends on individual surgeon preferences and training. Eight hospitals participated in this retrospective study. Data of 695 patients operated for ovarian cancer with primary colorectal anastomosis were included (January 2010-June 2018). Fourteen pre-/intraoperatively defined variables were identified and analysed as justification factors for use of diverting ileostomy.

RESULTS

The rate of diverting ileostomy in the entire cohort was 19.13% (133/695; range within individual centers 4.6-24.32%). Previous treatment with bevacizumab [OR 2.8 (1.3-6.1); p=0.01]; additional bowel resections [OR 3.0 (1.8-5.1); p<0.001]; extended operating time [OR 1.005 (1.003-1.006); p<0.001] and intra-operative red blood transfusion [OR 2.7 (1.4-5.3); p<0.001] were found to be independently associated with diverting ileostomy performance. Assuming a 7% AL rate cut-off, up to 51.8% of DI presented an AL risk below 7% and might have been spared.

CONCLUSIONS

The risk factors that drive the gynecologic oncology surgeons to perform a diverting ileostomy, seem to differ from the actual risk factors that we have identified to be associated with postoperative anastomotic leak. Broader awareness of the risk factors that contribute to a higher perioperative risk profile, will facilitate a better risk stratification process and possibly avoid unnecessary stoma formation in ovarian cancer patients.

Isospin Properties of Nuclear Pair Correlations from the Level Structure of the Self-Conjugate Nucleus ^{88}Ru

The low-lying energy spectrum of the extremely neutron-deficient self-conjugate (N=Z) nuclide _{44}^{88}Ru_{44} has been measured using the combination of the Advanced Gamma Tracking Array (AGATA) spectrometer, the NEDA and Neutron Wall neutron detector arrays, and the DIAMANT charged particle detector array. Excited states in ^{88}Ru were populated via the ^{54}Fe(^{36}Ar,2nγ)^{88}Ru^{*} fusion-evaporation reaction at the Grand Accélérateur National d'Ions Lourds (GANIL) accelerator complex. The observed γ-ray cascade is assigned to ^{88}Ru using clean prompt γ-γ-2-neutron coincidences in anticoincidence with the detection of charged particles, confirming and extending the previously assigned sequence of low-lying excited states. It is consistent with a moderately deformed rotating system exhibiting a band crossing at a rotational frequency that is significantly higher than standard theoretical predictions with isovector pairing, as well as observations in neighboring N>Z nuclides. The direct observation of such a "delayed" rotational alignment in a deformed N=Z nucleus is in agreement with theoretical predictions related to the presence of strong isoscalar neutron-proton pair correlations.

Risk factors for anastomotic leakage after colorectal resection in ovarian cancer surgery: A multi-centre study

OBJECTIVE

To determine pre-/intraoperative risk factors for anastomotic leak after modified posterior pelvic exenteration (MPE) or colorectal resection in ovarian cancer and to create a practical instrument for predicting anastomotic leak risk.

BACKGROUND

In advanced ovarian cancer surgery, there is rather limited published evidence, drawn from a small sample, providing information about risk factors for anastomotic leak.

METHODS

Eight hospitals participated in this retrospective study. Data on 695 patients operated for ovarian cancer with primary anastomosis were included (January 2010-June 2018). Twelve pre-/intraoperative variables were analysed as potential independent risk factors for anastomotic leak. A predictive model was created to stablish the risk of anastomotic leak for a given patient.

RESULTS

The anastomotic leak rate was 6.6% (46/695; range 1.7%-12.5%). A total of 457 patients were included in the final multivariate analysis. The following variables were found to be independently associated with anastomotic leakage: age at surgery (OR 1.046, 95% CI 1.013-1.080, p = 0.005), serum albumin level (OR 0.621, 95% CI 0.407-0.948, p = 0.027), one or more additional small bowel resections (OR 3.544, 95% CI 1.228-10.23, p = 0.019), manual anastomosis (OR 8.356, 95% CI 1.777-39.301, p = 0.007) and distance of the anastomosis from the anal verge (OR 0.839, 95% CI 0.726-0.971, p = 0.018).

CONCLUSIONS

Due to the low incidence of AL in ovarian cancer patients, a restrictive stoma policy based on the presence of risk factors should be the actual recommendation. Hand-sewn anastomosis should be avoided.

Fibrinolytic Potential and Antiphospholipid Antibodies in Systemic Lupus Erythematosus and Other Connective Tissue Disorders

We studied the fibrinolytic response before and after venous occlusion (VO) in 30 patients with systemic lupus erythematosus (SLE), 25 with rheumatoid arthritis (RA) and 25 with different connective tissue disorders. Results were compared in patients with and without antiphospholipid antibodies (APA) and a history of either thrombosis or abortions. Before occlusion plasma levels of tissue-type plasminogen activator (t-PA) antigen and its inhibitor (PAI-1) were significantly higher in the patient group (p <0.001). After occlusion, a low fibrinolytic activity on fibrin plates (p <0.005) was observed in the same group. t-PA capacity and t-PA release were similar in relation to controls. The plasma PAI-1 activity was significantly elevated in each group of patients (p <0.005) as compared to the control group. No significant differences with respect to t-PA and PAI-1 were observed in patients as to the presence or absence of thrombosis. There was also no correlation between the fibrinolytic changes and the presence of APA. It is concluded that an impairment of the fibrinolytic system, mainly related to increased PAI-1 levels, is present in most patients with connective tissue disorders, although these changes did not correlate with the presence of APA or the incidence of thrombosis.

[Consensus opinion on antifungal prophylaxis in haematologic patients: Results of the PROMIC project]

OBJECTIVE

Invasive fungal disease (IFD) is an important cause of morbidity and mortality in haematological patients. Antifungal prophylaxis (AFP) is indicated for a number of clinical scenarios in this group of patients. The aim of this study was to reach a consensus on IFD prophylaxis in haematological patients in order to optimize their management.

METHODS

A committee of experts in haematology and infectious diseases compiled a survey of 79 items with controversial aspects about antifungal prophylaxis in haematological patients. The survey was evaluated in two rounds by a panel of experts following a modified Delphi methodology.

RESULTS

Forty-four experts in haematology and infectious diseases answered the survey. After two evaluation rounds, consensus was reached in 67 of the 79 items (84.8%), specifically 48 items were consensually agreed on (60.7%) and 19 were disagreed on (24.0%). Consensus was reached on prophylaxis candidates profiles and questions related to indications, mechanisms of action, spectrum of activity, toxicity and interactions of antifungal were elucidated. The usefulness of micafungin in IFD prophylaxis was particularly analysed. The consensus reached was that micafungin is an antifungal to be considered in this context as its safety profile and lower interaction potential may be advantageous.

CONCLUSIONS

A broad consensus was found in the management of IFD prophylaxis in the haematological patient. This consensus provides practical indications about its optimal management and can help determine the profile of patients eligible for this type of intervention.

Durable complete remission with aromatase inhibitor therapy in a patient with metastatic uterine carcinosarcoma with poor performance status and coagulation disorders: a case report

BACKGROUND

Chemotherapy is considered the most appropriate treatment for metastatic uterine sarcoma, despite its limited efficacy. No other treatment has been conclusively proved to be a real alternative, but some reports suggest that anti-hormonal therapy could be active in a small subset of patients. We report the case of a patient with metastatic uterine carcinosarcoma with positive hormonal receptors and a complete pathological response.

CASE PRESENTATION

A 54-year-old white woman presented to our emergency room with hypovolemic shock and serious vaginal bleeding. After stabilization, she was diagnosed as having a locally advanced uterine carcinosarcoma with lymph nodes and bone metastatic disease. In order to control the bleeding, palliative radiotherapy was administered. Based on the fact that positive hormone receptors were found in the biopsy, non-steroidal aromatase inhibitor therapy with letrozole was started. In the following weeks, her general status improved and restaging imaging tests demonstrated a partial response of the primary tumor. Ten months after initiating aromatase inhibitor therapy, she underwent a radical hysterectomy and the pathological report showed a complete response. After completing 5 years of treatment, aromatase inhibitor therapy was stopped. She currently continues free of disease, without further therapy, and maintains a normal and active life.

CONCLUSIONS

This case shows that patients with uterine carcinosarcoma and positive hormone receptors may benefit from aromatase inhibitor therapy. A multidisciplinary strategy that includes local therapies such as radiation and/or surgery should be considered the mainstay of treatment. Systemic therapies such as hormone inhibitors should be taken into consideration and deserve further clinical research in the era of precision medicine.

Reliability and Validity of a Spanish Version of the Social Skills Rating System–Teacher Form

The aim of this study was to examine the psychometric properties of a Spanish version of the Social Skills Scale of the Social Skills Rating System–Teacher Form (SSRS-T) with a sample of children attending elementary schools in Puerto Rico ( N = 357). The SSRS-T was developed for use with English-speaking children. Although translated, adapted, and administered in Spanish, little was known about its psychometric properties. The authors evaluated the applicability of the Spanish SSRS-T by examining specifically its internal consistency, test-retest reliability, parent-teacher cross-informant correlations, and construct validity. Findings suggest that the Spanish SSRS-T is a valid and reliable instrument and support its potential utility in the early identification of social difficulties that may hinder the social, emotional, and academic adjustment of Latino children.

Agreement between preoperative transvaginal ultrasound and intraoperative macroscopic examination for assessing myometrial infiltration in low-risk endometrioid carcinoma

OBJECTIVE

To compare diagnostic performance of preoperative transvaginal ultrasound (TVS) and intraoperative macroscopic examination for determining myometrial infiltration in women with low-risk endometrial cancer, and to estimate the agreement between the two methods.

METHODS

This was a single-center observational study comprising women with preoperative diagnosis of well- or moderately differentiated endometrioid carcinoma of the endometrium. All women underwent preoperative TVS by a single examiner. According to the examiner's subjective impression, myometrial infiltration was stated as ≥ 50% or < 50%. Surgical staging was performed in all cases. Intraoperative macroscopic examination of the removed uterus was performed by pathologists who were unaware of the ultrasound findings, and myometrial infiltration was stated as ≥ 50% or < 50%. Definitive histological diagnosis of myometrial infiltration was made by frozen section analysis and was used as the gold standard. Sensitivity and specificity with 95% CIs were calculated for TVS and intraoperative macroscopic inspection and compared using McNemar's test. Agreement between TVS and intraoperative macroscopic inspection was estimated using Cohen's kappa index (κ) and percentage of agreement.

RESULTS

Of 209 eligible women, 152 were ultimately included. Mean (± SD) age was 60.9 ± 10.2 years, with a range of 32-91 years. Definitive histological diagnosis revealed that myometrial infiltration was < 50% in 114 women and ≥ 50% in 38 women. Sensitivity and specificity of TVS for detecting deep myometrial infiltration were 81.6% and 89.5%, respectively, whereas the respective values for intraoperative macroscopic examination were 78.9% and 90.4% (McNemar's test, P > 0.05 when comparing TVS and intraoperative macroscopic examination). Agreement between methods was moderate with κ = 0.54 (95% CI, 0.39-0.69) and percentage of agreement of 82%.

CONCLUSIONS

Although the agreement between preoperative TVS and intraoperative macroscopic examination for detecting deep myometrial infiltration was only moderate, both methods had similar accuracy when compared with frozen section histology. Preoperative TVS might reasonably be proposed as a method for assessing myometrial infiltration as an alternative to intraoperative macroscopic examination, especially when performed by an experienced examiner and image quality is not poor.

Transvaginal/transrectal ultrasound for preoperative identification of high-risk cases in well- or moderately differentiated endometrioid carcinoma

OBJECTIVE

To evaluate the role of transvaginal/transrectal ultrasound for preoperative identification of high-risk cases among women with well-differentiated (G1) or moderately differentiated (G2) endometrioid carcinoma of the endometrium.

METHODS

This was a single-center prospective observational cohort study comprising a consecutive series of women with a preoperative diagnosis of G1/G2 endometrioid carcinoma of the endometrium. All women underwent transvaginal or transrectal ultrasound examination by a single examiner. According to the examiner's subjective impression, patients were considered high risk if myometrial infiltration was ≥ 50% and/or involvement of the cervix and/or adnexa was suspected. FIGO surgical staging was performed in all cases. According to definitive histological data regarding myometrial infiltration, cervical involvement and adnexal involvement, women were classified as low risk (no myometrial infiltration, no cervical involvement and no adnexal involvement) or high risk (myometrial infiltration ≥ 50% and/or cervical involvement and/or adnexal involvement). Sensitivity, specificity and positive (LR+) and negative (LR-) likelihood ratios, with 95% CIs, of transvaginal/transrectal ultrasound for detecting stage ≥ IB were calculated. Agreement between risk determined by transvaginal/transrectal ultrasound and postoperative definitive histology was calculated.

RESULTS

Of 209 eligible women, 169 were included in the study. Mean (± SD) age of the study cohort was 60.7 ± 10.3 years, with a range of 32-91 years. Sensitivity, specificity, LR+ and LR- of transvaginal/transrectal ultrasound identifying high-risk cases according to myometrial infiltration, cervical involvement and adnexal involvement were 78.0% (95% CI, 63.7-88.0%), 89.1% (95% CI, 81.7-93.8%), 7.14 (95% CI, 4.19-12.18) and 0.25 (95% CI, 0.15-0.42), respectively.

CONCLUSIONS

Preoperative transvaginal/transrectal ultrasound may play a significant role in identifying high-risk cases among those with G1/G2 endometrioid carcinoma of the endometrium according to preoperative biopsy, and could be a useful test in this clinical setting.

Accuracy of transvaginal ultrasound for diagnosis of deep endometriosis in uterosacral ligaments, rectovaginal septum, vagina and bladder: systematic review and meta-analysis

OBJECTIVE

To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of endometriosis in the uterosacral ligaments (USL), rectovaginal septum (RVS), vagina and bladder in patients with clinical suspicion of deep infiltrating endometriosis (DIE).

METHODS

An extensive search was performed in MEDLINE (PubMed) and EMBASE for studies published between January 1989 and December 2014. Studies were considered eligible if they reported on the use of TVS for the preoperative detection of endometriosis in the USL, RVS, vagina and bladder in women with clinical suspicion of DIE using the surgical data as a reference standard. Study quality was assessed using the PRISMA guidelines and QUADAS-2 tool.

RESULTS

Of the 801 citations identified, 11 studies (n = 1583) were considered eligible and were included in the meta-analysis. For detection of endometriosis in the USL, the overall pooled sensitivity and specificity of TVS were 53% (95%CI, 35-70%) and 93% (95%CI, 83-97%), respectively. The pretest probability of USL endometriosis was 54%, which increased to 90% when suspicion of endometriosis was present after TVS examination. For detection of endometriosis in the RVS, the overall pooled sensitivity and specificity were 49% (95%CI, 36-62%) and 98% (95%CI, 95-99%), respectively. The pretest probability of RVS endometriosis was 24%, which increased to 89% when suspicion of endometriosis was present after TVS examination. For detection of vaginal endometriosis, the overall pooled sensitivity and specificity were 58% (95%CI, 40-74%) and 96% (95%CI, 87-99%), respectively. The pretest probability of vaginal endometriosis was 17%, which increased to 76% when suspicion of endometriosis was present after TVS assessment. Substantial heterogeneity was found for sensitivity and specificity for all these locations. For detection of bladder endometriosis, the overall pooled sensitivity and specificity were 62% (95%CI, 40-80%) and 100% (95%CI, 97-100%), respectively. Moderate heterogeneity was found for sensitivity and specificity for bladder endometriosis. The pretest probability of bladder endometriosis was 5%, which increased to 92% when suspicion of endometriosis was present after TVS assessment.

CONCLUSION

Overall diagnostic performance of TVS for detecting DIE in uterosacral ligaments, rectovaginal septum, vagina and bladder is fair with high specificity.

Transvaginal ultrasound for preoperative assessment of myometrial invasion in patients with endometrial cancer: a systematic review and meta-analysis

OBJECTIVE

To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of deep myometrial infiltration in patients with endometrial cancer, comparing subjective and objective methods.

METHODS

An extensive search was performed in MEDLINE (PubMed) and EMBASE for studies published between January 1989 and December 2014. The eligibility criterion was use of TVS for preoperative assessment of myometrial infiltration by subjective evaluation and/or objective measurements. Objective measurements included, specifically, the approaches of Gordon (ratio of the distance between endometrium-myometrium interface and maximum tumor depth to the total myometrial thickness) and Karlsson (endometrial tumor thickness/anteroposterior uterine diameter ratio), in women with endometrial cancer, using the surgical pathological data as a reference standard. Study quality was assessed using the QUADAS-2 tool.

RESULTS

Our extended search identified a total of 184 citations, among which we examined the full text of 24 articles. Overall pooled sensitivity, specificity, positive likelihood ratio (LR+) and negative likelihood ratio (LR-) of TVS for detecting deep myometrial infiltration were 82% (95% CI, 76-87%), 81% (95% CI, 76-85%), 4.3 (95% CI, 3.6-5.3) and 0.22 (95% CI, 0.16-0.30), respectively. We did not observe differences among the three methods in terms of diagnostic performance. Significant heterogeneity was found for sensitivity and specificity of all three methods (I(2) range, 60.6-95.0). The main limitation was that very few studies compared different approaches in the same set of patients.

CONCLUSION

Diagnostic performance of TVS for detecting deep myometrial infiltration in women with endometrial cancer is moderate.

Performance of three-dimensional power Doppler angiography as third-step assessment in differential diagnosis of adnexal masses

OBJECTIVE

To evaluate the contribution of three-dimensional (3D) power Doppler angiography (3D-PDA) to the differential diagnosis of adnexal masses.

METHODS

This was a prospective study in women diagnosed with a persistent adnexal mass and subsequently scheduled for surgery in a tertiary university hospital. All women were evaluated by transvaginal/transrectal ultrasound according to a predetermined three-step protocol, with transabdominal ultrasound being performed in some cases. First, morphological evaluation of the mass was performed using gray-scale 'pattern recognition' (first step). Lesions diagnosed as having a benign pattern were considered as being at low risk of malignancy whereas tumors with solid components, ascites and/or signs of carcinomatosis were considered as being at high risk of malignancy. In both cases no further test was performed and a decision regarding clinical management, either for follow-up or surgery, was taken. Tumors with solid components but without signs of ascites or carcinomatosis were considered as being at intermediate risk of malignancy. These lesions were assessed by two-dimensional (2D) PDA to evaluate tumor vascularity (color score) (second step). Solid tumors with a color score of 1 or 2 were considered as benign and no further test was performed, while tumors with a color score of 2, 3 or 4 within solid components or a color score of 3 or 4 in the case of a solid tumor were considered as malignant. The latter group underwent 3D-PDA assessment (third step). Vascularization index (VI) was calculated in a 1-mL sphere of the most vascularized area of the tumor. When a VI ≥ 24.015% was found, the tumor was considered as malignant. All masses were removed surgically and definitive histological diagnosis was used as the gold standard. Sensitivity and specificity for each strategy were calculated and compared. In the case of bilateral tumors, only the more suspicious one was used for analysis.

RESULTS

A total of 367 adnexal masses diagnosed in 367 women (mean age, 46.5 (range, 18-80) years) were evaluated during the study period. Of these, 86 masses were malignant and 281 were benign. The sensitivity and specificity for each assessment strategy were as follows: one-step, 97.7% and 78.6%; two-step, 94.2% and 97.9% (P < 0.001 for specificity when compared with that of one-step); three-step, 90.7% and 98.9% (not statistically significant when compared with that of two-step).

CONCLUSIONS

The addition of 2D-PDA in the differential diagnosis of an adnexal mass significantly increases specificity while sensitivity remains high; however performing subsequent 3D-PDA does not provide additional information or further improve diagnostic performance subsequent to 2D-PDA.

Intensive training program for ultrasound diagnosis of adnexal masses: protocol and preliminary results

OBJECTIVE

To assess the feasibility of a specific training program for ultrasound diagnosis of adnexal masses.

METHODS

A 2-month intensive training program was developed. The program protocol consisted of a 1-day intensive theoretical course focused on clinical and sonographic issues related to adnexal masses and ovarian cancer, followed by a 4-week real-time ultrasound training program in a tertiary center (25-30 adnexal masses evaluated per month) and a final 4-week period for offline assessment of three-dimensional (3D) volumes from adnexal masses. In this final period, each trainee evaluated five sets of 100 3D volumes. 3D volumes contained gray-scale and power Doppler information, and the trainee was provided with clinical data for each case (patient age, menopausal status and reported symptoms). 3D volumes were obtained from surgically removed masses that had undergone histological diagnosis or from masses that had been followed up until resolution. After assessment of each set, the trainee's diagnostic performance was calculated (sensitivity and specificity) and each incorrectly classified mass was evaluated with the trainer. The objective was to achieve a sensitivity of > 95% and a specificity of > 90%. Learning curve cumulative summation (LC-CUSUM) graphs were plotted to assess the learning curve for the trainees.

RESULTS

One trainer and two trainees with little experience in gynecological ultrasound (one gynecologist and one radiologist) participated in this study. LC-CUSUM graphs showed that competence was achieved after 170 or 185 examinations. The objectives for diagnostic performance were achieved after assessment of the second set of 3D volumes (200 cases) for each trainee.

CONCLUSIONS

The proposed training program appears to be feasible. High diagnostic performance can be achieved after analysis of 200 cases and maintained thereafter.

GEICO (Spanish Group for Investigation on Ovarian Cancer) treatment guidelines in ovarian cancer 2012

In 2006, under the auspices of The Spanish Research Group for Ovarian Cancer (Spanish initials GEICO), the first "Treatment Guidelines in Ovarian Cancer" were developed and then published in Clinical and Translational Oncology by Poveda Velasco et al. (Clin Transl Oncol 9(5):308-316, 2007). Almost 6 years have elapsed and over this time, we have seen some important developments in the treatment of ovarian cancer. Significant changes were also introduced after the GCIG-sponsored 4th Consensus Conference on Ovarian Cancer by Stuart et al. (Int J Gynecol Cancer 21:750-755, 2011). So we decided to update the treatment guidelines in ovarian cancer and, with this objective, a group of investigators of the GEICO group met in February 2012. This study summarizes the presentations, discussions and evidence that were reviewed during the meeting and during further discussions of the manuscript.

Expectant management of adnexal masses in selected premenopausal women: a prospective observational study

OBJECTIVE

To evaluate the results of expectant management of ovarian cysts with benign ultrasound morphology in selected asymptomatic premenopausal women.

METHODS

This was a prospective cohort study of premenopausal women diagnosed with a persistent adnexal cyst. Patients were selected according to symptoms (asymptomatic), the cyst's appearance on ultrasound (benign) and size (< 8 cm). Patients underwent a follow-up protocol with transvaginal ultrasound examination at 6-monthly intervals for 2 years and then annually for at least 3 years.

RESULTS

The study comprised 166 women (mean age, 40 years) with 192 masses present at inclusion. Twenty-two women (with 29 masses) were lost to follow-up. Seventy-four masses (38.5%) resolved spontaneously (median time from diagnosis to resolution, 40 months). Forty-nine masses (25.5%) persisted without change (median follow-up time, 88 (range, 36-192) months). Forty masses (20.8%) were surgically removed; 12 because of increase in size, four because a second lesion appeared during follow-up, three because of change in appearance and increase in size, five because of surgery for uterine benign or malignant disease, two because of change in appearance without increase in size, one because of clinical suspicion of ovarian torsion and 13 because of the patient's decision in spite of there being no change in the mass. Histology was benign in all but two cases (Stage Ia mucinous ovarian carcinoma and Stage Ia mucinous borderline tumor). During follow-up 40 new masses in 31 women were diagnosed, of which 21 resolved spontaneously, five (all with benign histology) were surgically removed and 14 were still present at the time of writing.

CONCLUSIONS

Expectant management of cysts with benign ultrasound morphology is a management option in selected asymptomatic premenopausal women.

The impact of the type of hospital on survival of multiple myeloma patients: the MICORE study

OBJECTIVE

To analyze the impact of the type of hospital in overall survival of multiple myeloma patients.

PATIENTS AND METHOD

A survival analysis was performed of all patients (n=431) diagnosed in 5 public hospitals (4 community hospitals and one university hospital) during the period 1993-2006.

RESULTS

Patients attended to in community hospitals differ significantly from those seen in the university hospital in the following variables: mean age (70 years [31-92] versus 67.9 (35-91), P=.038); percentage of stage iii patients (62.6% versus 69.1%, P=.033), and percentage of patients who had autologous stem cell transplant (8.2% versus 18.2%, P=.026). The variables associated with mortality in the multivariate analysis were age (P<.001), stage (iii versus i; P=.03) and renal failure (P=.04). The type of hospital did not reach statistical significance (hazard ratio of 0.72 (95% confidence interval 0.48-1.07), P=.1].

CONCLUSIONS

The type of hospital is not significantly associated with mortality in multiple myeloma patients. These data support our current model of health care, in which the community hospitals are responsible for the primary care of these patients, in a coordinated work with the university hospital.

Molecular and flow cytometry characterization during the follow-up of three simultaneous lymphoproliferative disorders: hairy cell leukemia, monoclonal B-cell lymphocytosis, and CD4(++) /CD8(+/- dim) T-large granular lymphocytosis--a case report

The simultaneous diagnosis of hairy cell leukemia and monoclonal B-cell lymphocytosis with the characteristics of "indolent" chronic lymphocytic leukemia is rare but not unknown. However, an association with a third clonal lymphoproliferative disorder has not previously been described. We report the simultaneous presence of hairy cell leukemia, monoclonal B-cell lymphocytosis, and alpha beta CD4(++) /CD8(+) T-cell large granular lymphocytosis in a 63-year-old man. After the diagnosis, the three lymphoproliferative disorders (i.e., two of B-cell lineage and one of T-cell lineage) were characterized by analysis of multiple sequential bone marrow and peripheral blood samples using flow cytometry and molecular techniques. We discuss these findings in the context of chronic antigen stimulation, immunosuppression, and apoptotic pathway alterations, which might be implicated in the accumulation of these abnormal clones in the same patient. Because the phenotype of the three clones is compatible with fully differentiated B lymphocytes (consistent with a postgerminal origin) and T-CD4(++) cells, we favor the possibility of an antigen-driven mechanism and a dysregulation of homeostatic apoptosis in this patient.

[Association between genetic polymorphism in the promotor region of CD209 and propensity to develop invasive pulmonary aspergillosis]

Fungi of the genus Aspergillus are found everywhere in the natural environment; they cause invasive pulmonary aspergillosis (IPA), an infectious complication common in immunocompromised individuals, which has a mortality rate of up to 90% in patients with hematological malignancy. The first line of defense of innate immunity is the recognition of Aspergillus conidia by dendritic cells or alveolar macrophages. DC-SIGN is an integrin directly involved in this recognition; its degree of expression in immune cells and its functionality may be partly determined by genetic variations. The objective of this study was to determine whether the presence of polymorphisms of a single nucleotide in the DC-SIGN gene increases the risk of invasive pulmonary aspergillosis. For this purpose, the variants DC-SIGN-139A/G (rs2287886) and DC-SIGN+11C/G (rs7252229) were analyzed In 314 subjects (152 patients with hematologic malignancy and 162 healthy controls). Of the 152 hematologic cancer patients, 81 were diagnosed with demonstrated invasive pulmonary aspergillosis per EORTC/IFICG criteria, and the remaining 71 patients had no symptoms of the infection. An association was found between the variant DC-SIGN-139(A/G) and resistance to IPA. Carriers of the allele A (A/A + A/G) were significantly more resistant to the infection than patients with the G/G genotype (p = 0.0574). Analysis of the serum concentration of the galactomannan antigen supported the hypothesis that this polymorphism may be implicated in the susceptibility to suffer invasive pulmonary aspergillosis. Although the difference was not statistically significant, carriers of the allele G had a higher frequency of positive galactomannans than subjects with the genotype A/A (p = 0.1921). These results suggest that the variant DC-SIGN-139(A/G) in the DC-SIGN gene promoter influences the risk of invasive pulmonary aspergillosis and may therefore be used as a genetic biomarker to stratify patients according to risk.

TNFR1 mRNA expression level and TNFR1 gene polymorphisms are predictive markers for susceptibility to develop invasive pulmonary aspergillosis

Tumour necrosis factor (TNF) is primarily secreted by monocytes/macrophages and activated T lymphocytes in response to fungal infections. TNF acts through TNF receptor 1 (TNFR1) triggering a pro-inflammatory response, and therefore plays a pivotal role in immune regulation and host immune responses. We hypothesized that single nucleotide polymorphisms (SNPs) in TNFR1 gene may influence the innate immune response against Aspergillus. Three SNPs were genotyped in 275 individuals (144 immunocompromised haematological patients with high-risk of developing IPA and 131 healthy controls): TNFR1(-383(A/C)) (rs2234649) and TNFR1(-609(G/T)) (rs4149570) in the 5 prime UTR region, and TNFR1(+36(A/G)) SNP (rs767455) in the first exon of the gene. Of the 144 haematological patients, 77 patients developed Invasive Pulmonary Aspergillosis (IPA) infection and the remaining 67 patients were not infected. TNFR1(+36(A/G)) and TNFR1(-609(G/T)) were associated with IPA susceptibility (p=0.033 and p=0.018, respectively). A role of TNFR1 genetic variants in the susceptibility of patients to develop IPA was also supported by the significantly lower TNFR1 mRNA expression level in IPA than in IPA-resistant patients and the strong correlation between the TNFR1(-609) genetic variant and the expression levels of TNFR1. There was also a tendency for a higher frequency of galactomannan (GM) positivity in patients with TNFR1(-609G/G) genotype than in patients with TNFR1(-609G/T) (p=0.0909) or TNFR1(-609T/T) (p=0.0913) genotype. Predictive sequence analysis of the effects of TNFR1(-609) promoter polymorphism revealed that this SNP might play a critical role in modifying the affinity of ICSBP/IRF-8, a transcription factor that is involved in the TNFR1-mediated activation of NFkappaB signalling pathway. Taken together, these data suggest that TNFR1 polymorphisms influence the risk of IPA disease and might be useful for risk stratification strategies. These findings need to be confirmed in validation studies with larger samples of haematological patients.

Three-dimensional power Doppler angiography in endometrial cancer: correlation with tumor characteristics

OBJECTIVE

To assess the correlation between intratumoral vascularization using three-dimensional power Doppler angiography (3D-PDA) and several histological tumor characteristics in a series of patients with endometrial carcinoma.

METHODS

Ninety-nine women (mean age, 61.7 (range, 31-84) years) diagnosed as having endometrial cancer were assessed by transvaginal 3D-PDA before surgical staging. Endometrial volume (EV) and 3D-PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) were calculated using the Virtual Organ Computer-aided AnaLysis (VOCAL) method. All patients were surgically staged. Individual tumor features such as histological type, tumor grade, myometrial infiltration depth, lymph-vascular space involvement, cervical involvement, lymph node metastases and tumor stage were considered for analysis. Multivariate logistic regression (MLR) analysis was used to determine which 3D-PDA parameters were independently associated with each histological characteristic.

RESULTS

MLR analysis showed that only EV and VI were independently associated with myometrial infiltration (EV: odds ratio (OR), 1.119 (95% CI, 1.025-1.221), P = 0.012; VI: OR, 1.127 (95% CI, 1.063-1.195), P = 0.001) and tumor stage (EV: OR, 1.103 (95% CI, 1.012-1.202), P = 0.025; VI: OR, 1.120 (95% CI, 1.057-1.187), P = 0.001), only VI was independently associated with tumor grade (OR, 1.056 (95% CI, 1.023-1.091), P = 0.001) and only EV was independently associated with lymph node metastases (OR, 1.086 (95% CI, 1.017-1.161), P = 0.001).

CONCLUSION

3D-PDA analysis of tumor vascularization in endometrial cancer correlates with some prognostic histological characteristics.

Triage for surgical management of ovarian tumors in asymptomatic women: assessment of an ultrasound-based scoring system

OBJECTIVES

To prospectively evaluate an ultrasound-based scoring system as a method for triaging asymptomatic women presenting with an adnexal mass for surgical treatment.

METHODS

Two hundred and four adnexal masses in 189 asymptomatic women undergoing elective surgical treatment at our institution were included in this prospective study. Patients were evaluated by transvaginal power Doppler ultrasound imaging before surgery. Patients were classified as low risk or high risk for malignancy according to an ultrasound-based scoring system. Women with a low risk for malignancy were scheduled for laparoscopy and patients with a high risk for malignancy were scheduled for laparotomy. However, patients classified as low risk by the ultrasound scoring system, but with a tumor size >or= 10 cm or clinical suspicion of pelvic adhesions, were instead considered to be at intermediate risk and were scheduled for laparotomy. Some patients classified as high risk were scheduled for an operative laparoscopy by an expert in gynecological oncology.

RESULTS

One hundred and thirty-four (65.7%) masses were considered to be low risk and were treated by a laparoscopically guided procedure. All these tumors were benign. Forty-seven (23%) masses were classified as high risk, of which 39 tumors were malignant and eight benign. Twenty-three (11.3%) tumors were considered to be intermediate risk and were scheduled for primary laparotomy. In this group, 21 (91.3%) tumors proved to be benign and two (8.7%) were malignant.

CONCLUSIONS

Ultrasound-based triage of asymptomatic women diagnosed with a persistent adnexal mass is effective for selecting the surgical approach.

IL1 gene cluster polymorphisms and its haplotypes may predict the risk to develop invasive pulmonary aspergillosis and modulate C-reactive protein level

OBJECTIVE

The aim of this study was to determine whether interleukin-1 alpha (IL1alpha), interleukin-1 beta (IL1beta), and IL1 receptor antagonist (IL1Ra) polymorphisms are implicated in invasive pulmonary aspergillosis (IPA) pathogenesis.

MATERIALS AND METHODS

Subjects comprised 110 hematological patients and 148 healthy controls. Genotypic and allelic frequencies were similar between hematological patients and controls. IPA was diagnosed in 59 of the 110 patients according to consensus criteria published by the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group (EORTC/IFICG).

RESULTS AND DISCUSSIONS

Individual locus analysis showed that IL1alpha and IL1Ra polymorphisms were not associated with the presence of IPA (p = 0.560 and p = 0.680, respectively). However, a trend towards a higher presence of IL1beta( - ) (511TT) genotype (or IL1beta(-511T) allele) in the IPA group than in the non-IPA patient group (p = 0.092 and p = 0.095, respectively) was found. Haplotype analysis revealed that VNTR2/-889C/-511T haplotype was strongly associated with susceptibility to develop IPA infection (p = 0.020). Haplotype analysis also showed an association between VNTR2/-889C/-511C haplotype and resistance to IPA infection (p = 0.028). Furthermore, patients with IL1Ra VNTR2/2 and IL1beta(-511)T/T genotypes had a higher positive serum galactomannan percentage versus patients with other genotypes. Finally, C-reactive protein (CRP) production was significantly associated with IL1 gene cluster polymorphisms, although CRP values were similar between IPA and non-IPA groups.

CONCLUSION

These findings indicate a critical role of IL1 gene cluster polymorphisms in the susceptibility to IPA infection and CRP production.

Extraperitoneal laparoscopic para-aortic lymphadenectomy as a diagnostic procedure for lymph node recurrence of gynaecological cancers

OBJECTIVE

The aim of this study was to evaluate the feasibility of extraperitoneal laparoscopic para-aortic lymphadenectomy for lymph node recurrence of gynecological cancers.

METHODS

Seven patients underwent extraperitoneal laparoscopic para-aortic lymphadenectomies for suspected lymph node recurrence, detected by magnetic resonance image or CT scan. The suspicious nodes were removed through an extraperitoneal laparoscopic approach.

RESULTS

The median age of patients was 51 years (range: 39-67). The median operating time was 207 min (range 120-300). There were no intraoperative or postoperative complications. The median nodal yield was 7.3 (range: 1-15). The median hospital stay was 2.5 days (range: 2-3). Histological examination revealed metastasis in 6 of the 7 patients.

CONCLUSION

The extraperitoneal laparoscopic para-aortic lymphadenectomy for lymph node recurrence of gynecological cancers is a safe and feasible procedure which should be considered in the case of possible recurrence.

Genetic markers on HIV-1 gp120 C2-V3 region associated with the expression or absence of cognitive motor complex in HIV/AIDS

In the CNS, HIV-1 causes cognitive motor complex (CMC) in about 30-40% of patients. To explain CMC physiopathology: disequilibrium of cytokine networks, calcium influx, free radicals and toxic effects by HIV-1 have been evoked. Neurotropic mutants have not been unambiguously proven nor 'variants' of HIV-1 with biological properties that could cause CMC. By computerized analysis of gp120 C2-V3 subtype B sequences from retroviral databases, and applying stringent criteria, we found: (i) mutations specific for CMC; (ii) mutations associated with the absence of CMC (N-CMC); (iii) mutations with specificity for the geographical region of origin, and finally (iv) shared mutations representing 'hot spots.' We suggest that the capability to cause or not to cause CMC may be present in the virus prior to infection. In the future, these markers could be used to guide treatments with novel neuroprotective regimes.

Adaptation of parent-child interaction therapy for Puerto Rican families: a preliminary study

This study examines how parent-child interaction therapy (PCIT) was adapted for Puerto Rican parents of children aged 4-6 with hyperactivity and other significant behavior problems. Four steps were followed: (1) translation and preliminary adaptation of the treatment manual, (2) application of the treatment to 9 families as part of an exploratory study using repeated measures, (3) treatment revision and refinement, and (4) in-depth interviews with parents (n=15) and clinical psychologists (n=5) from Puerto Rico who provided feedback on treatment process and components. Throughout this process, cultural elements and modifications were recommended to be incorporated into the treatment protocol. Both quantitative and qualitative results suggest that PCIT seems to be an acceptable intervention for this population, with some minor changes. Parents reported a high level of satisfaction, a significant reduction in children's externalizing behavior problems, and reduction of parenting stress and improvement in their parenting practices. Psychologists also evaluated positively the treatment protocol and recommended its use. Results from this study may inform clinicians and researchers who work with Latino families about relevant issues to be considered to promote their participation in behavioral family interventions and to enhance their acceptability and effectiveness.

Characterization of molds from dry-cured meat products and their metabolites by micellar electrokinetic capillary electrophoresis and random amplified polymorphic DNA PCR

Molds are common contaminants of dry-cured meat products in which mycotoxins could be synthesized if stored under favorable conditions. Thus, efficient and accurate characterization of the toxigenic molds from dry-cured meat products is necessary. A micellar electrokinetic capillary chromatography (MECC) method was tested to analyze secondary metabolites produced by 20 mold strains commonly found in dry-cured meat products. In addition, their random amplified polymorphic DNA (RAPD) genotypes were determined by using a PCR method. Although peak profiles of the secondary metabolites differed among mold strains of different species, they were similar in the same species. MECC analysis showed that 10 of the 20 molds tested produced mycotoxins, including patulin, penicillic acid, cyclopiazonic acid, mycophenolic acid, aflatoxin B1, sterigmatocystin, and griseofulvin. The RAPD analysis yielded a different pattern for each of the mold species tested. However, strains of the same species showed similar RAPD profiles. A high correlation between RAPD analysis and MECC was observed, since strains of the same species that showed similar RAPD patterns had similar profiles of secondary metabolites. RAPD patterns with primer GO2 and MECC profiles, either singly or combined, could be of great interest to distinguish toxigenic from nontoxigenic molds in dry-cured meat products.

Microbiological quality of terrestrial gastropods prepared for human consumption

Hygienic quality was investigated in 60 samples of ready-to-eat snails (Helix lactea, Helix nemoralis, and Helix hortensis) obtained from 30 in-season street stalls and 30 catering establishments (bars) in Córdoba. In accordance with Spanish legislation regarding hygiene in the preparation, distribution, and sale of prepared foods, counts were obtained for total mesophilic aerobic bacteria, coliforms, total Enterobacteriaceae, Escherichia coli, Salmonella, and Staphylococcus aureus. The results obtained showed that 33.3, 20.0, and 13.3% of the samples from stalls and 73.3, 53.3, and 6.7% of the samples from bars did not comply with the regulations with respect to the control of total mesophilic aerobic bacteria, Enterobacteriaceae, and Staphylococcus aureus, respectively. Coliforms were found in 53.3% of the samples from the bars (mean, 2.1 CFU/g) and in 33.3% of the stalls (mean, 1.1 CFU/g). Salmonella was not detected.

Safety of the concomitant use of caspofungin and cyclosporin A in patients with invasive fungal infections

Caspofungin, an echinocandin antifungal agent, is active against invasive Aspergillus and Candida infections. In a phase I study in healthy volunteers, mild transient increases in serum aminotransferases were observed with the concomitant administration of caspofungin and cyclosporin A (CsA). As a result, it is recommended that the concomitant use of the two drugs be limited to those settings with appropriate risk-benefit balance. We retrospectively assessed safety data in 14 patients with refractory invasive mycoses who were treated concomitantly with CsA and caspofungin before the drug was licensed in Spain. In all, 13 patients were adults (median age, 31.5 years; range, 14-67 years). The average duration of concomitant therapy was 15 days (range, 2-43 days). No clinically significant elevations of serum aminotransferases were observed, and no patient had concomitant therapy discontinued or interrupted due to a drug-related adverse event. In this study of a limited number of patients, the coadministration of caspofungin and CsA was generally well tolerated.

Vaginal Reconstruction Using a Modified Rectus Abdominis Musculocutaneous Flap in Pelvic Cancer Surgery

The authors present a modification of the design for the classic cutaneous pattern of the rectus abdominis musculocutaneous flap for vaginal reconstruction after pelvic cancer surgery. The authors designed a paramedial and supraumbilical dermo-cutaneous flap with paraumbilical randomized vascularization, which was sutured to the classic cutaneous TRAM flap pattern and rotated around a longitudinal axis to form the neo-introitus. The use of this new cutaneous design allows for a perfect cylindrical shape all along the length of the new vagina, thus achieving a more anatomic reconstruction than those currently obtained with the classic cutaneous patterns, and with fewer tendencies to distal retraction, necrosis, and partial stenosis.

Intratumoral blood flow in cervical cancer as assessed by transvaginal color doppler ultrasonography: Correlation with tumor characteristics

The objective of this study was to evaluate whether intratumoral blood flow as assessed by transvaginal color Doppler ultrasonography (TVCD) correlates with some tumor features in cervical cancer. Clinical, sonographic, and histologic data on 49 women (mean age: 50.3 years, range: 25-85 years) diagnosed as having a carcinoma from the uterine cervix were reviewed. Intratumoral blood flow was assessed by TVCD in all cases. Subjective impression of the amount of flow (scanty, moderate, or abundant) as well as the lowest resistance index (RI) and highest peak systolic velocity (PSV, cm/s) were used for analysis. These data were correlated with some tumoral features such as histologic type, histologic grade, tumor volume, and tumor stage. Intratumoral blood flow was found in all cases. Abundant blood flow was found more frequently in squamous carcinoma, moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.0001). Significantly lower RI was found in moderately or poorly differentiated tumors and advanced stage tumors (P < 0.01) and significantly higher PSV was found in moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.01). No correlation was found between RI and PSV and histologic type. Our data indicate that intratumoral blood flow as assessed by TVCD correlates well with some tumor features in cervical cancer.
