RESUMO
OBJECTIVE: An overview of current knowledge about the use of 3D ultrasound examinations for the examination of fetal CNS. DESIGN: A review article. SETTING: Department of Gynecology and Obstetrics, Faculty of Medicine and Dentistry, Palacký University and Faculty Hospital Olomouc. METHODS: Literary sources related to the subject were used, especially articles indexed by Pubmed-Medline. CONCLUSION: 3D ultrasound is currently used for examination of fetal CNS structures that can be only very difficult displayed by conventional 2D ultrasound. The best for technique for visualisation of midline fetal CNS structures, respectively corpus callosum cerebellar vermis, appears to be 3D volume acquisition in a sagittal plane through the sagittal suture or large fontanel with further post-processing in multiplanar mode, OVIX (Samsung), TUI (GE Healthcare) etc.

INTRODUCTION: Indocyanine green (ICG) fluorescence imaging system is a now a consolidated complementary technique for several surgical fields. The development of post-transplant lymphocele following lymph spread could affect kidney function; between therapeutic options, the literature reports a 12% overall conversion rate from laparoscopic to open surgery with a major risk of damaging the urinary tract. OBJECTIVE: The goal of the present study was to demonstrate that intraoperative ICG fluorescent imaging is a safe technique that can be used in laparoscopy establishing the exact location of the lymphocele and reducing intraoperative risks. METHOD: Fifty milligrams of ICG dissolved in 20 mL of saline solution was injected via percutaneous drainage placed into the lymphocele to decompress transplanted kidneys 2 weeks before a laparoscopic lymphocele marsupialization procedure. RESULTS: During the first exploratory laparoscopy, in the flank and right iliac fossa, near the 2 renal grafts, fluorescence was identified in 3 raised areas that were the internal side of the lymphocele lobes. The lymphocele wall was dissected and 300 mL of serous fluid was aspirated after puncturing. A 5 cm breach was then made in the cyst wall using the Ultracision harmonic scalpel (Ethicon US). Afterwards, a pedicle of the omentum in the lymphocele core was interfered with and fixed by 2 stitches. CONCLUSIONS: Laparoscopic surgery seems to be the preferred surgical option for the treatment of primary symptomatic lymphocele after kidney transplantation. Intraoperative ICG fluorescent imaging is a safe technique to establish the exact location of the lymphocele and reduces the risk of damaging urinary structures during surgery.

Aortoiliac occlusive disease (AOD) is a great threat for kidney transplantation (KT). Here we report the case of an aortoiliac bypass, performed simultaneously with renal transplantation using venous grafts obtained from the deceased donor. The recipient was a 68-year-old woman with significant stenosis of the aortoiliac axis. We performed an aortobisiliac bypass using donor's femoral veins because presence of methicillin-resistant Staphylococcus aureus was detected on donor hemoculture and contraindicated a prosthetic implant on the recipient. KT was then carried out using standard technique. Operative time amounted to 330 minutes and cold ischemia time of the renal graft was 900 minutes. Delayed graft function was observed until postoperative day 12, but the patient showed a good urine output and a serum creatinine of 2.1 mg/dL at discharge. AOD is not an absolute contraindication to renal transplantation, and simultaneous surgical repair of aortoiliac lesions with KT seems feasible. The patient's return to function after initial delayed graft function suggests that such interventions may allow transplantation to be offered to those patients who otherwise may be excluded for severe vascular comorbidities. Homologous vascular grafts are an excellent choice because prosthetic vascular replacement during immunosuppression must be avoided as long as possible, especially in patients with coexisting infective risk.

BACKGROUND: Many surgical procedures can produce persistent lymphorrhea, lymphoceles, and lymphedema after lymph node and lymph vessel damage. Appropriate visualization of the lymphatic system is challenging. Indocyanine green (ICG) is a well-known nontoxic dye for lymphatic flow evaluation. ICG fluorescence-guided lymphography has emerged as a promising technique for intraoperative lymphatic mapping. OBJECTIVE: Our goal was to develop a high spatial resolution, real-time intraoperative imaging technique to avoid or recognize early deep lymphatic vessel damage. METHODS: We intraoperatively performed ICG fluorescence-guided lymphography during a kidney transplant. ICG was injected in the subcutaneous tissue of the patient's groin in the Scarpa's triangle. A dedicated laparoscopic high-definition camera system was used. RESULTS: Soon after ICG injection, the lymphatic vessels were identified in the abdominal retroperitoneal compartment as fluorescent linear structures running side by side to the iliac vessels. Surgical dissection was therefore performed, avoiding iatrogenic damage to major lymphatic structures. Another ICG injection at the end of the procedure confirmed that the lymphatic vessels were intact without lymph spread. CONCLUSIONS: Intraoperative lymphatic mapping with an ICG fluorescence-sensitive camera system is a safe and feasible procedure. ICG real-time fluorescence lymphography can be used to avoid or recognize early deep lymphatic vessel damage and reduce postoperative complications related to the lymphatic system.

BACKGROUND: Recent meta-analyses suggested that screening program for abdominal aortic aneurysms (AAA) in 65-year old males is cost-effective at prevalence of about 1%. Since some events occur also in females and among the youngers, screening could be feasible among those at higher risk, such as smokers or individuals with a family history of AAA. The RoCAV (Risk of Cardiovascular diseases and abdominal aortic Aneurysms in Varese) Project is a population-based study aimed to evaluate AAA prevalence in Northern Italy in males over-65 years as well as among females and younger males, and to identify new markers for risk stratification by collecting a large set of CVD risk factors. The aims of the project are: (i) cross-sectional evaluation of AAA prevalence (ii); evaluation of standard CVD risk score as criteria for selecting subgroup at higher risk to be included in a screening program; (iii) identification of new risk markers and risk score algorithm for AAA and CVD risk stratification; (iv) cost-effective evaluation during the follow-up. METHODS: Males aged 50-75 years and females aged 60-75 years, resident in the city of Varese (Lombardy Region), were randomly selected from the civil registry. Among 5198 successfully invited, 3777 subjects accepted to participate and were finally recruited (participation rate 63.8%) from June 2013 to May 2016. Trained operators administered a computerized anamnestic questionnaire, measured anthropometric parameters (BMI, body circumferences, skinfolds), blood pressure, ankle-brachial index, pulse wave velocity and performed abdominal aortic ultrasound scan, ECG and spirometry. All methods were internationally validated. A blood sample was collected and stored in biobank. A follow-up will be carried out through linkage with electronic records. DISCUSSION: Participation rate and data quality assessment were as expected and will reasonably allow to reach the project aims. The expected impact in public health of the RoCAV project will be the potential implementation of a AAA screening program to the whole region as well as the formulation of new criteria for risk assessment of AAA and CVD.

The development of various sophisticated mechanical thrombectomy devices and the amassed experience of physicians in minimal invasive therapy produced a paradigm shift in vascular access management toward percutaneous declotting procedures, using pharmaceutical thrombolysis, mechanical thrombectomy, balloon thrombectomy, and a combination of the above techniques. In this setting, in the last years, AngioJet™ (Possis, Minneapolis, MN, USA) rheolytic thrombectomy (RT) showed an increasing use in emergency and election patients. The purpose of this review is to present the current status of percutaneous rheolytic thrombectomy in different fields of applications.

Cytosolic 5'-nucleotidase II (cN-II) has been reported to be involved in cell survival, nucleotide metabolism and in the cellular response to anticancer drugs. With the aim to further evaluate the role of this enzyme in cell biology, we stably modulated its expression the human glioblastoma cell ADF in which the transient inhibition of cN-II has been shown to induce cell death. Stable cell lines were obtained both with inhibition, obtained with plasmids coding cN-II-targeting short hairpin RNA, and stimulation, obtained with plasmids coding Green Fluorescence Protein (GFP)-fused wild type cN-II or a GFP-fused hyperactive mutant (GFP-cN-II-R367Q), of cN-II expression. Silenced cells displayed a decreased proliferation rate while the over expressing cell lines displayed an increased proliferation rate as evidenced by impedance measurement using the xCELLigence device. The expression of nucleotide metabolism relevant genes was only slightly different between cell lines, suggesting a compensatory mechanism in transfected cells. Cells with decreased cN-II expression were resistant to the nucleoside analog fludarabine confirming the involvement of cN-II in the metabolism of this drug. Finally, we observed sensitivity to cisplatin in cN-II silenced cells and resistance to this same drug in cN-II over-expressing cells indicating an involvement of cN-II in the mechanism of action of platinum derivatives, and most probably in DNA repair. In summary, our findings confirm some previous data on the role of cN-II in the sensitivity of cancer cells to cancer drugs, and suggest its involvement in other cellular phenomenon such as cell proliferation.

For several years the IMP/GMP-preferring cytosolic 5'-nucleotidase II (cN-II) has been considered as a therapeutic target in oncology. Indeed, various reports have indicated associations between cN-II expression level and resistance to anticancer agents in several cancer cell lines and in patients affected with neoplasia, mainly by hematologic malignancies. In this paper we present evidence showing that, among the commonly used cytotoxic nucleoside analogs, fludarabine can act as a cN-II inhibitor. In vitro studies using the wild type recombinant cN-II demonstrated that fludarabine inhibited enzymatic activity in a mixed manner (Ki 0.5 mM and Ki' 9 mM), whereas no inhibition was observed with clofarabine and cladribine. Additional experiments with mutant recombinant proteins and an in silico molecular docking indicated that this inhibition is due to an interaction with a regulatory site of cN-II known to interact with adenylic compounds. Moreover, synergy experiments between fludarabine and 6-mercaptopurine in human follicular lymphoma (RL) and human acute promyelocytic leukemia (HL-60) cells transfected with control or cN-II-targeting shRNA-encoding plasmids, showed synergy in control cells and antagonism in cells with decreased cN-II expression. This is in line with the hypothesis that fludarabine acts as a cN-II inhibitor and supports the idea of using cN-II inhibitors in association with other drugs to increase their therapeutic effect and decrease their resistance.

Among the members of the 5'-nucleotidase family, there is only one membrane-bound ectosolic isoenzyme. This esterase prefers AMP as substrate but can hydrolyze a number of purine and pyrimidine phosphorylated compounds, indicating that no evolutive pressure to develop a more restricted specificity was exerted on this enzyme. On the contrary, five cytosolic isoforms have been evolved, probably by convergent evolution, showing different and restricted substrate specificity. The different isoforms have different level of expression and distribution in organs of vertebrates. The cytosolic nucleotidase specific for IMP and GMP (cN-II), is an enzyme allosterically regulated, structurally strongly conserved and expressed at a low but constant level in all organs and tissues in vertebrates. As far as we know, alteration of cN-II expression is limited to pathological conditions. In this review, we report the results of the modulation of cN-II specific activity exerted by silencing or hyperexpression in different cell types, in the attempt to better understand its role and implications in pathology and therapy.

Pseudoaneurysm of inferior epigastric artery (IEA) is a very rare clinical entity. We reported a case of combined kidney transplant and pseudoaneurysmectomy in a young HBV-HCV-HIV recipient. This case emphasizes the possibility of planning a safe and correct surgical treatment and the best timing to treat IEA pseudoaneurysm. An exhaustive preoperative radiological study in all patients candidate to kidney transplant could identify the possible aortoiliac disease both stenotic or dilatative even if it is rare and helps to define the best treatment options.

The advent of combined antiretroviral therapy (cART) dramatically changed the view of human immunodeficiency virus (HIV) infection as an exclusion criterion for solid organ transplantation, resulting in worldwide reports of successful transplants in HIV-infected individuals. However, there are few reports on simultaneous pancreas-kidney transplant in HIV-positive recipients detailing poor outcomes. A series of four pancreas-kidney transplant performed on HIV-infected individuals between 2006 and 2009 is presented. All recipients reached stably undetectable HIV-RNA after transplantation. All patients experienced early posttransplant infections (median day 30, range 9-128) with urinary tract infections and bacteremia being most commonly observed. In all cases, surgical complications led to laparotomic revisions (median day 18, range 1-44); two patients underwent cholecystectomy. One steroid-responsive acute renal rejection (day 79) and one pancreatic graft failure (month 64) occurred. Frequent dose adjustments were required due to interference between cART and immunosuppressants. At a median follow-up of 45 months (range, 26-67) we observed 100% patient survival with CD4 cell count >300 cells/mm(3) for all patients. Although limited by its small number, this case series represents the largest reported to date with encouraging long-term outcomes in HIV-positive pancreas-kidney transplant recipients.

AIM: The purpose of this study was to review the outcomes of endovascular treatment and open repair of visceral artery aneurysms, and to compare their results. METHODS: Between January 1995 and January 2009, 42 patients (22 males) underwent surgical or endovascular treatment for visceral artery aneurysms. Mean age was 60 ± 13 (range, 35-85). Overall, 12 patients (25%) were asymptomatic, twenty-six patients (54.2%) were symptomatic, and 10 aneurysms (20.8%) were ruptured. The first 12 cases (28.6%) were treated with open repair; thereafter, endovascular techniques were used to treat 30 VAAs (71.4%). RESULTS: Ten patients were treated in emergency setting [8 in the endovascular group (26.6%) and 2 in the open repair group (16.7%), P=0.491]. In the endovascular group, primary technical success was achieved in 29 of 30 VAAs (96.6%). Overall in-hospital mortality was 2.4%. Major complications occurred in 8 patients (3 endovascular vs 5 open repair, P=0.01). Overall, mean hospitalization was 9.7 vs. 13 days (P<0.0001). Mean follow-up was 64 months (range, 3 months-14 years). In the endovascular group, reperfusion was higher in larger (>5 cm) aneurysms (P<0.0001). CONCLUSION: Endovascular techniques could be the first treatment option for all visceral artery aneurysms.

Tuberculosis (TB) is a serious infection in immunocompromised patients, such as solid organ transplant recipients and HIV-infected patients. The diagnosis and treatment in this population present several challenges because of the aspecific clinical manifestations, the difficulty in diagnosis, and the choice of the most appropriate therapeutic regimen. Therapeutic challenges arise from drug-related toxicities, interactions between immunosuppressive, antiretroviral, and antituberculous drugs. We present a case of primary TB infection that occurred 3 years after transplantation in a HIV-and hepatitis C virus-coinfected kidney-pancreas recipient. The infection was successfully treated with no hepatotoxicity or rejection with a non-rifampin-containing regimen.

Preoperative anemia creates a challenge for surgical treatment and patient outcomes after major surgery. Prior to a surgical intervention, it is optimal to increase erythropoiesis to improve oxygen transport through the bloodstream for patients at high risk of anemia and to avoid the complications of allogeneic blood transfusion. In this way, patients could receive predeposited autologous blood or, during the surgical procedures, undergo acute normovolemic hemodilution. This approach is allowed by the use of recombinant human erythropoietin in association with erythropoiesis-inducing factors such as iron and folic acid. In this article, we discuss the recent clinical evidences.

OBJECTIVE: To assess the expression of immunohistochemical markers in surgically staged endometrial cancer patients. METHODS: We studied 107 cases of primary untreated endometrial carcinoma in which the p53, bcl-2, her-2/neu, Ki-67, estrogen receptor (ER) and progesterone receptor (PR) antigens were investigated by an immunohistochemical method. In the last 50 consecutive patients immunoreactivity for MMP-7 and MMP-26 was assessed as well. We evaluated the correlations among the immunohistochemical staining assessed by histoscore, and the age, grading, depth of invasion, stage of the neoplasia and extrauterine disease. RESULTS: Mean age was 65 years (range 34-88). All patients were submitted to total abdominal or modified radical vaginal hysterectomy plus bilateral salpingo-oophorectomy and systematic pelvic lymphadenectomy; p53, bcl-2, her-2/neu, Ki-67, MMP-7, MMP-26, estrogen and progesterone receptors were positive in 36 (43%), 71 (86%), 13 (16%), 80 (96%), 65 (78%), 80 (96%), 61 (73%) and 71 (86%) patients, respectively. p53 overexpression was found to be related to poor grade of differentiation and deep myometrial invasion. Immunostaining for ER was inversely related to the histopathological differentiation of the tumors. Decreased expression of PR was related to advanced stage, poor histopathologic differentiation and extrauterine spread of disease. CONCLUSION: The overexpression of p53 seems to indicate more malignant phenotype, while PR expression correlates with parameters of better clinical outcome.

OBJECTIVE: To assess the immunohistochemical expression of p53, bcl-2, c-erbB-2, Ki-67, estrogen (ER) and progesterone receptors (PR), MMP-7, MMP-26 in samplex from diagnostic hysteroscopy and therapeutic hysterectomy in endometrial cancer patients. DESIGN: Experimental prospective study. SETTING: Department of Obstetrics and Gynecology, Institute of Human Genetics, Department of Pathology, Palacky University Medical School and University Hospital, Olomouc. METHODS: We studied 43 cases of primary untreated endometrial carcinoma in which the grade and immunomarkers assessed by histoscore were investigated in specimens obtained at hysteroscopy and hysterectomy. RESULTS: Based on hysterosopy, 31 (72.1%) patients were classified as G1, G2 7 (16.3%) and G3 5 (11.6%) respective. In grade 1 the concordance rate was 77.4% of cases, in grade 2 it was in 14.3% of cases and in grade 3 it was in 80.0% of cases. In hysterosocpy samples the p53 expression was found in 23 (53.5%), bcl-2 in 37 (86.0%), c-erbB-2 in 20 (46.5%), Ki-67 in 29 (67.4%), ER in 37 (86.0%), PR in 36 (83.7%), MMP-7 in 25 (58.1%) and MMP-26 in 23 (53.5%) cases. Expression in hysterectomy specimens was p53 positive in 13 (30.2%), bcl-2 positive in 33 (76.7%), c-erbB-2 positive in 24 (55.8%), Ki-67 positive in 25 (58.1%), ER positive in 36 (83.7%), PR positive in 40 (93.0%), MMP-7 positive in 27 (62.8%) and MMP-26 positive in 23 (53.5%) of total 43 cases. CONCLUSION: We found high concordance in expression of p53, bcl-2, PR and MMP-7 in hysteroscopy and hysterectomy samples which could be of importance for therapeutic algorithm in endometrial cancer patients.

First described in 1989, HIV-related aneurysms have been rarely reported. Considered atypical if compared to classic atherosclerotic diseases, they show no preferred location and frequently involve young patients with no other risk factors for atherosclerosis but with an impaired immune system. They are probably related to an auto-immune damage inside the aortic wall associated with a necrotizing perivasculitis. Visceral artery aneurysms are rare and life-threatening diseases; the superior mesenteric and gastro-duodenal and pancreatic vessels are rarely involved. The advantages related to the endovascular approach to these aneurysms seems to be even more effective in immuno-impaired patients (i.e. HIV+). We report a case of a young patient affected by a HIV-related gastroduodenal artery aneurysm which was treated with a combined percutaneous and endovascular approach.
