RESUMEN

PURPOSE: Tall stature is defined as height greater than the threshold of more than 2 standard deviations above the average population height for age, sex, and ethnicity. Many studies have described the main aspects of this condition during puberty, but an analysis of the characteristics that the physician should consider in the differential diagnosis of gigantism-tall stature secondary to a pituitary tumour-during the transition age (15-25 years) is still lacking. METHODS: A comprehensive search of English-language original articles was conducted in the MEDLINE database (December 2021-March 2022). We selected all studies regarding epidemiology, genetic aspects, and the diagnosis of tall stature and gigantism during the transition age. RESULTS: Generally, referrals for tall stature are not as frequent as expected because most cases are familial and are usually unreported by parents and patients to endocrinologists. For this reason, lacking such experience of tall stature, familiarity with many rarer overgrowth syndromes is essential. In the transition age, it is important but challenging to distinguish adolescents with high constitutional stature from those with gigantism. Pituitary gigantism is a rare disease in the transition age, but its systemic complications are very relevant for future health. Endocrine evaluation is crucial for identifying conditions that require hormonal treatment so that they can be treated early to improve the quality of life and prevent comorbidities of individual patient in this age range. CONCLUSION: The aim of our review is to provide a practical clinical approach to recognise adolescents, potentially affected by gigantism, as early as possible.

RESUMEN

PURPOSE: The immune environment represents a new, but little explored, tool for understanding neuroendocrine neoplasms (NENs) behavior. An immunosuppressed microenvironment is hypothesized to promote NENs progression. A missing profiling of circulating leukocyte and peripheral blood mononuclear cells (PBMCs) subpopulations would open new perspectives in the still limited diagnostic-therapeutic management of NENs. METHODS: A cross-sectional case-control pilot study was performed recruiting 30 consecutive subjects: 15 patients naïve to treatment, with histologically proven gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) and 15 healthy controls, matched for age and sex. PBMCs subpopulations were studied by flow cytometry. Soluble Tie2 (sTie2), Angiopoietin-1 (Ang-1), Angiopoietin-2 (Ang-2) were evaluated by ELISA. RESULTS: Immune cell profiling revealed a significant lower CD3-CD56+ natural killer (NK) cell count in NETs vs controls (p = 0.04). NK subset analysis showed a reduced relative count of CD56+CD16+ NK cells (p =0.002) in NETs vs controls. Patients with NET showed a higher percentage of CD14+CD16++ non-classical monocytes (p = 0.01), and a lower percentage of CD14+CD16+ intermediate monocytes (p = 0.04). A decrease in percentage (p = 0.004) of CD4+ T-helper lymphocytes was found in NET patients. Evaluation of cellular and serum angiopoietin pathway mediators revealed in NET patients a higher relative count of Tie2-expressing monocytes (TEMs) (p < 0.001), and high levels of Ang-1 (p = 0.003) and Ang-2 (p = 0.002). CONCLUSIONS: Patients with GEP-NET presented an immunosuppressed environment characterized by a low count of cytotoxic NK cells, a high count of anti-inflammatory non-classical monocytes, and a low count of T-helper lymphocytes. Higher levels of TEMs and angiopoietins suggest a crosstalk between innate immunity and angiogenic pathways in NETs.

RESUMEN

BACKGROUND: Sellar/parasellar lesions have been studied in the adult and paediatric age range, but during the transition age their epidemiology, clinical manifestations, management and treatment outcomes have been poorly investigated. MATERIALS AND METHODS: An Italian multicentre cohort study, in which hospital records of patients with diagnosis of sellar/parasellar lesions during the transition age and young adulthood (15-25 years), were reviewed in terms of prevalence, clinical and hormonal features at diagnosis, and outcomes where available. Both pituitary neuroendocrine tumours (pituitary tumours, Group A) and non-endocrine lesions (Group B) were included. RESULTS: Among Group A (n = 170, 46.5% macroadenomas), the most frequent were prolactin and GH-secreting tumours, with a female predominance. Among Group B (n = 28), germinomas and Rathke cells cysts were the most common. In Group A, the most frequent hormonal deficiency was gonadal dysfunction. Galactorrhoea and amenorrhoea were relatively common in female patients with prolactinomas. Pre-surgical diabetes insipidus was only seen in Group B, in which also hormone deficiencies were more frequent and numerous. Larger lesions were more likely to be seen in Group B. Patients in Group B were more frequently male, younger, and leaner than those of Group A, whereas at last follow-up they showed more obesity and dyslipidaemia. In our cohort, the percentage of patients with at least one pituitary deficiency increased slightly after surgery. CONCLUSIONS: The management of sellar/parasellar lesions is challenging in the transition age, requiring an integrated and multidisciplinary approach. Hormone and metabolic disorders can occur many years after treatment, therefore long-term follow-up is mandatory.

RESUMEN

OBJECTIVE: The nonavalent HPV vaccine has demonstrated its efficacy in women and men who already suffer from HPV genital lesions, with little chances to clear the infection. The efficacy of new therapeutic or complementary alternatives as Ellagic acid plus Annona Muricata (Ellagic acid complex) has emerged recently. Our retrospective study compares the evolution of persistent cervical HPV infection in two cohorts of immunocompetent women after the administration of nonavalent vaccine or Ellagic acid complex. PATIENTS AND METHODS: At Tor Vergata University Hospital, Rome, forty women in childbearing age, suffering from persistent cervical HPV infection, were enrolled in two study's groups: nonavalent HPV vaccine (20 women) vs. Ellagic acid complex tablets (20 who refused the vaccine). Cytological features, HPV DNA genotypes and mRNA oncogenic genes E6/E7 presence and clearance were analyzed and confronted between the groups. RESULTS: Demographics and clinical features of the cohorts were comparable. Evaluation of Pap smear, HPV DNA test and mRNA genes E6/E7, were performed at baseline (T0) and after 6 months (T1) and 12 months (T2) from the last dose of vaccine/tablet. At T1 and T2, Ellagic acid complex group showed a statistical reduction of abnormalities in Pap smears (p = 0.018 and 0.006, respectively), probably due to its direct anti-inflammatory, antioxidative and antiviral activities. At T1, vaccinated group showed a higher rate of HPV clearance (p = 0.001), instead Ellagic acid complex group didn't report significative differences. At T2, respect to T0, both groups showed an increase in percentage of negative HPV DNA detection, although more marked for vaccinated group respect to Ellagic acid complex group (p = 0.039 and 0.062 respectively). Regarding mRNA E6/E7 clearance, at T1 and T2, the group of vaccinated women showed a higher negativization respect to the other group (p= 0.077 and 0.042, respectively). CONCLUSIONS: Despite the limited sample of women enrolled for the present study, the results confirmed the clinical usefulness of HPV vaccination as adjuvant agent for the immune system of women affected by persistent HPV infection. Moreover, in women who refused to be vaccinated, the administration of a biocompound like Ellagic acid plus Annona Muricata, represented an interesting clinical strategy in terms of increasing chance of HPV viral clearance.

RESUMEN

PURPOSE: Risk factors for sporadic GEP-NENs are still not well defined. To identify the main clinical risk factors represents the aim of this study performed by three Italian referral centers for NENs. METHODS: We performed a retrospective case-control study including 148 consecutive sporadic GEP-NENs and 210 age- and sex-matched controls. We collected data on clinical features, cancer family history and other potential risk factors. RESULTS: Mean age was 58.3 ± 15.8 years; 50% males, primary site was pancreas (50.7%), followed by ileum (22.3%). The 62.8% and 29.1% of cases were G1 and G2, respectively; the 40% had locally advanced or metastatic disease at diagnosis. Independent risk factors for GEP-NENs were: family history of non-neuroendocrine GEP cancer (OR 2.16, 95% CI 1.31-3.55, p = 0.003), type 2 diabetes mellitus (T2DM) (OR 2.5, 95% CI 1.39-4.51, p = 0.002) and obesity (OR 1.88, 95% CI 1.18-2.99, p = 0.007). In the T2DM subjects, metformin use was a protective factor (OR 0.28, 95% CI 0.08-0.93, p = 0.049). T2DM was also associated with a more advanced (OR 2.39, 95% CI 1.05-5.46, p = 0.035) and progressive disease (OR 2.47, 95% CI 1.08-5.34, p = 0.03). Stratifying cases by primary site, independent risk factors for pancreatic NENs were T2DM (OR 2.57, 95% CI 1.28-5.15, p = 0.008) and obesity (OR 1.98, 95% CI 1.11-3.52, p = 0.020), while for intestinal NENs family history of non-neuroendocrine GEP cancer (OR 2.46, 95% CI 1.38-4.38, p = 0.003) and obesity (OR 1.90, 95% CI 1.08-3.33, p = 0.026). CONCLUSION: This study reinforces a role for family history of non-neuroendocrine GEP cancer, T2DM and obesity as independent risk factors for GEP-NENs and suggests a role of metformin as a protective factor in T2DM subjects. If confirmed, these findings could have a significant impact on prevention strategies for GEP-NENs.

RESUMEN

OBJECTIVE: The aim of the study was to evaluate the sensitivity and specificity values of high-risk HPV DNA test, p16/ki-67, and HPV mRNA in histologically high-grade cervical intraepithelial lesions (CIN2-CIN3) in women aged 21-24 years with diagnosis of atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL) at pap smear. PATIENTS AND METHODS: 342 patients between 21-24 years old, attending spontaneously our clinics, 118 with ASCUS and 224 with LSIL, were enrolled in the study. All patients underwent colposcopy and biopsies were performed in the areas with major changes. All patients were tested at the same time for p16/ki-67, high-risk HPV DNA and HPV mRNA. RESULTS: Nineteen out of 118 women with ASCUS showed a high-grade cervical intraepithelial lesion, 11 out of 118 (9.32%) CIN2, and 8 out of 118 (6.78%) CIN3. The sensitivity of high-risk HPV DNA was 99.9%, and the specificity 23.2%; p16/ki-67 pointed out a sensitivity of 90.9%, and a specificity of 81.8%; HPV mRNA showed a sensitivity of 81.8%, and specificity of 87.9% in CIN2 lesions. In CIN3 lesions, the sensitivity of high-risk HPV DNA was 99.9%, while the specificity was 19.1%; p16/ki-67 showed a sensitivity of 99.9%, and a specificity of 73.7%; HPV mRNA relived a sensitivity of 87.5%, and a specificity of 80.8%. In women with LSIL, a total of 42/224 (18.75%) of CIN2 were found at the histopathological examination, while 17/224 (7.59%) women presented a CIN3. No case of invasive cancer was identified. High-risk HPV DNA was positive in 190/224 (84.8%), p16/ki-67 in 119/224 (53.1%), and HPV mRNA in 104/224 (46.4%). In women with CIN2, the sensitivity of high-risk HPV DNA was of 92.8%, and the specificity 17.5%, the sensitivity of p16/ki-67 was 95.2%, and specificity 61.8%. HPV mRNA showed a sensitivity of 88.8% and a specificity of 87.8%. In women with CIN3, the sensitivity of high-risk HPV DNA was 88.2%, and the specificity 29.7%; p16/ki-67 pointed out a sensitivity of 94.1%, and a specificity of 49%; HPV mRNA showed a sensitivity of 88.2% and a specificity of 80.6. CONCLUSIONS: Taking into account the high rate of spontaneous regression of high-grade lesions in young women, these tests, in particular, the HPV mRNA test, used as a triage test for ASCUS or LSIL, can modify follow-up triage strategy. In fact, this biomarker, due to its high specificity, could lead to a cytology repetition instead of an immediate colposcopy, avoiding over diagnosis and potential overtreatment in this category of women.

RESUMEN

OBJECTIVE: In the last years, the mean age of women who underwent cervical treatment for high-grade cervical intraepithelial neoplasia (CIN 2-3) is similar to the age of women having their first pregnancy. The aim of this study was to evaluate the risk of preterm birth in subsequent pregnancies after loop electrosurgical excision procedure (LEEP). PATIENTS AND METHODS: From January 2013 to January 2016 the study identified a total of 1435 women, nulliparous, who underwent LEEP for CIN 2-3, and who wished to have their first pregnancy. Before surgery, the lengths of the cervix were calculated by transvaginal sonography. After the treatment, the dimension of the removed tissue was evaluated. During the pregnancy, all women carried out periodic transvaginal sonography and vaginal-cervical swabs. RESULTS: The average age of patients was 31.96±5.24 years; the interval between the surgical procedure and pregnancy was 12.04±4.67 months; the gestational age at births was 37.53±2.91 weeks. The first vaginal and cervical swab performed during pregnancy was negative in 81.8% of patients. The most prevalent infections were related to C. Albicans, G. Vaginalis, and Group B Streptococcus (GBS). The rate of preterm delivery was significantly higher in women with a minor cervical length. CONCLUSIONS: The length and the volume of cervical tissue excised have been shown to be directly related to the risk for preterm birth. Furthermore, vaginal infections and their persistence during pregnancy in women with a history of LEEP may be associated with an increased risk for preterm birth, compared with women with no history of LEEP.

RESUMEN

OBJECTIVE: The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found. The aim of this work was to assess the proper management of abnormal cytology during and after pregnancy evaluating regression rate, persistence rate and risk of progression and the predictive role of HPV molecular tests. PATIENTS AND METHODS: Patients with abnormal cervical cytology were followed-up using colposcopy and colposcopy-directed biopsies every 12 weeks. Molecular tests were performed at the moment of the cytological diagnosis. Patients not treated in pregnancy were re-evaluated with cytology, colposcopy, biopsies, HPV-DNA test and HPV-mRNA test for a final diagnosis 8 weeks postpartum. Women with a persistent CIN 2-3 lesion at this follow-up check, underwent an excisional procedure by LEEP and then re-evaluated every 6 months for a year. RESULTS: HPV-DNA test showed a sensitivity of 90.5% and a negative predictive value of 96.4%. Specificity and positive predictive values were 67.9% and 43.2%, respectively. For HPV-mRNA test, a sensitivity of 76.2% and a NPV of 93.9% were found; specificity and PPV were 98.7% and 94.1% respectively. CONCLUSIONS: An observational management based on the use of molecular test and particularly HPV-mRNA test for its higher specificity, is a reasonable possibility in the follow-up of CIN2/3 lesions during pregnancy.

RESUMEN

OBJECTIVE: Vulvar intraepithelial neoplasia (VIN) is a premalignant lesion of the vulva. The incidence of VIN is increasing. The surgery is currently the gold standard therapy for VIN, but Imiquimod could be a completion to surgery. The aim of this study is to compare the overall complete response, the recurrence rate and the risk factors for recurrence among two groups of patients: women with high grade VIN underwent surgery and patients treated with surgery plus Imiquimod. PATIENTS AND METHODS: 80 patients with histologically diagnosed VIN 2/3 were enrolled in this prospective study. Our patients were divided into two groups: 40 women underwent surgery (A) and 40 patients were treated with surgery plus Imiquimod (B). All women had a 5-year follow-up. Recurrence rate and complete response were evaluated. The following patients' characteristics were analyzed: smoke, multifocal disease, multicentric disease, degree of the lesion. RESULTS: In the group A recurrence rate was 44.8%, in the group B it was 48.4%. In both groups the presence of multifocal lesions (p = 0.02) and VIN 3 (p = 0.006) before treatment was associated with a higher risk of recurrence. CONCLUSIONS: This study found that surgery remains the principal approach for VIN with regard to relapse and complete response since the treatment with Imiquimod associated with surgery didn't show a lower recurrence rate. Although the surgical treatments remain the best therapeutic option for VIN with regard to recurrence and overall complete response, the combined therapy seems to be an interesting modality, but further studies are needed.

RESUMEN

BACKGROUND: Vulvar intraepithelial neoplasia (VIN) is a premalingnant condition. For long time, surgery was considered the first-line therapy in the treatment of high grade VIN. Imiquimod was recently introduced as an alternative to surgery. AIM: To compare the overall complete response, the recurrence rate and the risk factors for relapse among patients with VIN 2/3 treated with Imiquimod or surgical excision. PATIENTS AND METHODS: Eighty women who had histological diagnosis of VIN 2 and VIN 3 were enrolled in this prospective study. Patients immunocompromised, with recurrent VIN, with well differentiated type VIN or VIN 1 and women treated more than once were excluded from the study. Patients were divided into two groups: group A was treated with Imiquimod, group B underwent surgical excision. Patients' characteristics analyzed were: age, smoking, degree of the primary lesion, state of margins, multifocal disease. We have evaluated the recurrence rate, the relapse rate, and the overall complete response, considering as recurrence the onset of a lesion after an initial complete response to Imiquimod and/or after the surgical treatment and as relapse all patients who had a recurrence plus those with medical treatment failure. RESULTS: Multifocal lesions (p = 0.03) and VIN 3 (p = 0.002) were associated with a higher risk of relapse. The recurrence rate was higher in the group B (p = 0.009), but the relapse rate was higher in the group A (p = 0.04). The overall complete response was better in the group B (p = 0.04). CONCLUSIONS: Although the advent of new medical options can decrease the morbidity associated with invasive surgical procedures, surgical treatments remain the best treatment modality for VIN with regard to relapse and overall complete response.

RESUMEN

OBJECTIVE: The aim of this study was to compare liquid-based endometrial cytology with hysteroscopy and endometrial biopsy regarding its diagnostic accuracy in a series of postmenopausal women with abnormal uterine bleeding (AUB) or asymptomatic women with thickened endometrium assessed by transvaginal ultrasound as a screening procedure. METHODS: Inclusion criteria were: menopausal status; the presence of AUB and/or thickened endometrium assessed by ultrasound (cut-off 4 mm); a normal Papanicolaou (Pap) smear; and no adnexal pathology at ultrasound. Exclusion criteria were: previous endometrial pathology; and previous operative hysteroscopy. Of 768 postmenopausal women referred to our general gynaecology clinics, 121 fulfilled the inclusion criteria and were recruited to the trial. Twenty-one refused to participate. Cytological sampling was carried out by brushing the uterine cavity using the Endoflower device with no cervical dilation and the vial was processed using a ThinPrep® 2000 automated slide processor. The slides were stained using a Pap method. RESULTS: In 98 cases with histological biopsies, endometrial cytology detected five cases of endometrial carcinoma, 10 of atypical hyperplasia and 47 of non-atypical hyperplasia; 36 cases were negative. In two cases cytology was inadequate because of uterine cervical stenosis. Taking atypical hyperplasia or worse as a positive test and outcome, the diagnostic accuracy of the endometrial cytology was 93.5%, with a sensitivity of 92% and specificity of 95%, a positive predictive value of 73% and a negative predictive value of 99%. All the carcinomas were detected by cytology. Only 42% of women with a positive diagnosis were symptomatic. The cytological sampling was well tolerated by all patients. No complication was registered. CONCLUSIONS: Liquid-based endometrial cytology can be considered an useful diagnostic method in the detection of endometrial pathology as a first-line approach, particularly if associated with transvaginal ultrasound.

RESUMEN

Human papillomavirus (HPV) is the most common sexually transmitted agent worldwide. Prevalence varies according to the geographic regions, and is highest in developing countries. Geographic differences exist also in the detection rate of oncogenic types in malignant cervical lesions. In this study, the prevalence of HPV infection as well as the spectrum of HPV types was evaluated in Italian and immigrant women of the urban area of Rome. Several risk factors (age at first intercourse, number of partners, smoking, pregnancy, age at first pregnancy, contraception, education, and menarche) were taken into consideration. Overall, there was a high prevalence of HPV infection in the two groups studied. No significant differences were observed in the spectrum of HPV types detected. HPV 16 and 18 were the types detected more frequently in both groups. Interestingly, HPV 54 and 70 were found only in the immigrants. Whether this finding reflects a recent introduction of these HPV types in the population studied remains to be established. Monitoring of HPV types in the population is advisable, especially in countries like Italy which is a destination and a gateway for immigrants directed towards north and central Europe. The introduction of high risk HPV variants may have a clinical impact and affect the diagnostic procedures.

RESUMEN

OBJECTIVE: The Ulmsten's "Integral Theory" for pelvic floor dysfunctions is based on the need to reinforce fascias and ligaments with prostheses to obtain a reconstitution of the pelvic floor's anatomy. In September 2004 we developed a "uterine-sparing" surgical technique to correct such pathologies and in this paper we present results obtained. Primary outcome was to evaluate the technique's efficacy, secondary outcomes the resolution of stress urinary incontinence, postoperative pain (VAS scale), safety and complications. STUDY DESIGN: This prospective study included patients affected by stage 3 and 4 uterine-vaginal prolapse who wished to conserve their uterus. Those with (1) minor degrees of severity, (2) unfit for surgery, (3) with a clear indication to hysterectomy (i.e. endometrial cancer), (4) with an elevated operative risk (American Society of Anaesthesiologists-ASA score III and IV), (5) previous vaginal surgeries and (6) with moderate/severe defecation problems were excluded. The technique consisted in a sacrospinous colposuspension with polypropylene mesh. The pelvic status was classified according to the international Pelvic Organ Prolapse staging system (POP-Q). Postoperative pain was scored with the VAS Scale. All patients were given the King's Health questionnaire, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Wexner questionnaire. RESULTS: From September 2004 to November 2006 we treated 80 patients. Polypropylene prostheses (Gynemesh-Soft PS, 10cmx15cm - GyneMesh, Gynecare Ethicon - Somerville, NJ, USA) were used to reconstruct the pubo-cervix or the recto-vaginal fascia. We performed an anterior-central vaginal reconstruction in 35 (43.8%) patients, central-posterior in 25 (31%) and total reconstruction in 20 (25%). The median follow-up was 21 months (range 18-26). The severe pelvic prolapse, evaluated with the POP-Q System, was completely treated in all the patients and no recurrences were observed. The urodynamic examination showed a complete resolution of the stress urinary incontinence in 10 patients (83%). Sexual activities improved in all patients. We recorded three vaginal erosions and one patient complained of a postoperative dyspareunia. CONCLUSIONS: This pilot study suggests that our technique is safe and effective and can efficiently repair the pelvic organs prolapse, without undergoing hysterectomy and with a low rate of vaginal erosions.

RESUMEN

TVT-O and TVT were compared in patients stratified according the severity of Stress Urinary Incontinence (SUI). Those patients with intrinsic sphincter deficiencies, overactive bladders, associated prolapses, neurovegetative disorders and recurrent SUI or under rehabilitative/medical therapies were all excluded. There were 208 women included. Operating times were longer, and postoperative pain greater for TVT (p < 0.001). TVT produced longer hospitalizations in severe SUI patients (p < 0.001). After 1 year of follow-up, incontinence was cured in all mild SUI patients with both techniques, in all severe SUI patients when treated with TVT and in 66% of them when treated with TVT-O (p < 0.001). Vaginal perforations occurred during the TVT-O (p = 0.01), bladder perforations during TVT (p = NS), bladder obstructions in mild SUI patients after TVT (p < 0.001). The severity of SUI is an important parameter that influences results after TVT-O and TVT, and could be used to guide surgeons in selecting the most effective intervention.

RESUMEN

BACKGROUND: Isobaric gasless laparoscopy and minilaparotomy have been used as more recent minimally invasive approaches to myomectomy. This randomized trial aimed to compare the surgical and immediate postoperative outcomes for myomectomy performed by isobaric gasless laparoscopy with those for minilaparotomy. METHODS: A total of 100 patients with symptomatic uterine myomas requiring myomectomy were randomly allocated to the gasless laparoscopy group or the minilaparotomy group. The randomization procedure was based on a computer-generated list. The primary outcome was a comparison of the discharge times between the two procedures. A power calculation verified that more than 26 patients for each group was necessary to detect a difference of more than 24 h in discharge time with an alpha error level of 5% and a beta error of 80%. Continuous outcome variables were analyzed using the Student's t-test. Discrete variables were analyzed with the chi-square test or Fisher's exact test. A p value less than 0.05 was considered statistically significant. RESULTS: The mean discharge time was longer for minilaparotomy than for gasless laparoscopy (98.4 +/- 1.4 vs 52.8 +/- 1.6 h; p < 0.001). Gasless laparoscopy resulted in shorter times for canalization (21.6 +/- 1.1 vs 32 +/- 1.3 h; p < 0.05) and surgery (79.5 +/- 25.1 vs 103.5 +/- 24.9 min; p < 0.001). The intraoperative blood loss was less with gasless laparoscopy (154.2 +/- 1.2 vs 188.6 +/- 1.3 ml; p < 0.001). No intraoperative complications occurred, and no case was returned to the theater in either group. No conversion to standard laparotomy was necessary. CONCLUSIONS: Isobaric gasless laparoscopy and minilaparotomy can be suitable options for uterine myomectomy. Several surgical and immediate postoperative outcomes were significantly better in the gasless laparoscopy group than in the minilaparotomy group. However, further controlled prospective studies are required to confirm the results.

RESUMEN

We present 1-year results obtained with Reemex for the cure of intrinsic sphincter deficiencies (ISDs). We recruited all patients with primary cases of stress urinary incontinence (SUI) due to an ISD (Valsalva leak-point pressure less than 60 cm or maximal urethral closure pressure less than 20 cm) who did not receive previous surgery. Thirty-eight patients were operated on. Postoperative pain was 3 (range, 1-5, visual analogue scale) at 24 h from surgery. Immediate regulation (the day after surgery) was necessary in three of 38 patients (7.9%), two for obstructive voiding difficulties and one for incontinence. Late regulation was necessary in three of 38 patients (7.9%), two for obstructive voiding difficulties (after 6 months) and one for incontinence (1 year). Symptoms resolved after the sling adjustment. Our results suggest that sling adjustments resolve postoperative failures and maintain the success rate of the Reemex system even in the midterm.

RESUMEN

BACKGROUND: This study aimed to evaluate the feasibility and safety of isobaric laparoscopic removal of large myomas (> or = 8 cm) using the Laparotenser, a subcutaneous abdominal wall-lifting system. METHODS: A series of 63 consecutive patients with at least one large symptomatic subserosal or intramural uterine myoma (> or = 8 cm) underwent an isobaric gasless laparoscopic myomectomy. Conventional laparotomy instruments were used. RESULTS: The procedure was successfully completed for all 63 consecutive patients. The average size of the dominant myoma was 11 cm. The mean number of myomas removed from each patient was 3.6. The mean blood loss was 143 ml, and the mean operating time was 72 min. No intraoperative complication occurred. CONCLUSIONS: Gasless laparoscopic myomectomy for the removal of large myomas using the Laparotenser is feasible and safe. It offers several advantages over laparoscopy with pneumoperitoneum.

RESUMEN

Signal transduction through the IGF axis is implicated in proliferation, differentiation and survival during development and adult life. The IGF axis includes the IGF binding proteins (IGFBPs) that bind IGFs with high affinity and modulate their activity. In neuroblastoma (NB), a malignant childhood tumor, we found that IGFBP-5 is frequently expressed. Since NB is an IGF2-sensitive tumor, we investigated the relevance and the function of endogenous IGFBP-5 in LAN-5 and in SY5Y(N) cell lines transfected with micro and small interfering RNAs directed to IGFBP-5 mRNA. Cells in which IGFBP-5 expression was suppressed were growth-inhibited and more prone to apoptosis than the parental cell line and controls. Apoptosis was further enhanced by X-ray irradiation. The ability of these cells to undergo neuronal differentiation was impaired after IGFBP-5 inhibition but the effect was reversed by exposure to recombinant IGFBP-5. Together, these data demonstrate the importance of IGFBP-5 for NB cell functions and suggest that IGFBP-5 might serve as a novel therapeutic target in NB.
