Abstract
Streptococcus agalactiae (Lancefield group B Streptococcus), is the most frequent microorganism involved in neonatal infections through the mother-fetus vertical transmission. It is also responsible for infections in pregnant women, and adults with underlying diseases. The objective of this work was to know the S. agalactiae carrier prevalence in pregnant women who attended to Posadas Hospital, and to study the susceptibility pattern of the isolates to penicillin, erythromycin and clindamycin. From 1203 pregnant women studied, S. agalactiae was recovered in 113, which means a prevalence of 9.39%. Antimicrobial susceptibility was tested to 87 isolates. All of them were susceptible to penicillin, and only 2 isolates were resistant to erythromycin and clindamycin (constitutive MLS mechanism). We emphasize the importance of knowing these last resistance, in the case of beta-lactam antibiotics allergic women.

Abstract
AIM Video-assisted thoracoscopy surgery (VATS) is classically performed using general anesthesia with a double-lumen endotracheal tube to allow collapse of the operated lung. However, according to our opinion, the risks of general anesthesia with one-lung ventilation could be accepted when major thoracic operation is planned, but it should be avoided or kept at minimum when performing less invasive procedures such as video-assisted talc pleurodesis. In this paper, 2 different protocols are described in order to demonstrate the effectiveness and safety of Monitored Anesthesia Care (MAC) for performing VATS talc pleurodesis. METHODS We studied 65 neoplastic patients ASA III-IV who underwent video-assisted pleurodesis with talc nebulization. They were randomized into 2 homogenous groups: Group 1, received midazolam (0.015-0.030 mg/kg) and sufentanil (0.15-0.20 microg/kg); Group 2, received midazolam (0.15-0.2 mg/kg) and continuous remifentanil infusion 0.5-1 microg/kg/min in the first minute, followed by 0.05 microg/kg/min. Local anesthesia with 0.2% ropivacaine was employed before the thoracoscopic trocar was inserted in both groups. Intraoperative standard monitoring required ECG, heart rate, non-invasive blood pressure, transcutaneous carbon dioxide and oxygen saturation. Consciousness status has been evaluated by Ramsey scale, while pain intensity by VAS scale. RESULTS No statistically significant fluctuations were observed for mean arterial pressure, heart rate, SpO(2), tCO(2), VAS and Ramsey score. No postoperative complications and hospital mortality occurred. CONCLUSIONS Both the protocols offer an efficient control of analgosedation with a minimum incidence of intraoperative and postoperative side effects. Anyway, the titration of the drug is very important.

Abstract
AIM The aim of the study was to 1) evaluate the gestational age at diagnosis and the incidence of single umbilical artery in an unselected population of 3750 pregnant women; 2) identify its association with malformations and/or karyotype aberrations in pre/postnatal age; 3) evaluate the fetal-neonatal outcome; 4) investigate the likelihood that a fetus might be affected by a cytogenetic abnormality even in presence of an apparently ''isolated'' single umbilical artery. METHODS Transabdominal ultrasound of the umbilical vessels and histological confirmation at birth. In presence of single umbilical artery an accurate prenatal ultrasound assessment, karyotyping (pre/postnatal), and clinical follow-up after birth were performed. RESULTS The incidence of single umbilical artery in our population resulted 1.07% (40/3750), being ''isolated'' in 40% of cases. The diagnosis of chromosomal aberration associated with single umbilical artery was made in 6 cases (15%), while structural fetal abnormalities in absence of causal chromosomal anomalies were present in 9 cases (22.5%), with syndromic patterns in 3 of them. In 2 cases with chromosomal anomalies the single umbilical artery was apparently ''isolated'' at the ultrasound examination between the 17th and the 22nd week of gestation. Excluding 4 terminations of pregnancy, the perinatal mortality percentage resulted 25% (9/36); similarly, fetal growth retardation was present in 25% of cases (9/36). CONCLUSIONS The incidence of single umbilical artery in our population confirms that this fetal vascular anomaly is frequently identified in pregnancy. In the light of our cases and data in the literature it is evident that diligent surveillance in prenatal age and accurate clinical follow-up after birth are mandatory when a single umbilical artery has been diagnosed. Finally, the possibility, even if rare, that even when the single umbilical artery is apparently ''isolated'', a chromosomal aberration might be present (1/24 of our ''isolated'' cases) should be considered when addressing correct counselling to the couples.

Abstract
BACKGROUND Within the framework of the Progetto Faenza, the aim of this study was to evaluate the effect of cardiovascular risk factors (CVRF) on the health-related Quality of Life (H-rQoL) of a cohort of patients in the province of Ravenna, on the basis of body mass index (BMI). METHODS The following data were collected for each subject: age, sex, weight, height, glycemia, cholesterol (total, HDL and LDL), creatinine, uricemia, systolic arterial pressure (SAP) and diastolic arterial pressure (DAP), presence/absence of previous CV disorders, arterial hypertension, diabetes, antihypertensive therapy, smoking habits and physical exercise. To evaluate the H-rQoL the SF-36 general health survey questionnaire was used, filled in by the patient at the first examination. To test the significance of the differences between the groups (divided by classes of Body Mass Index) as regards the metabolic indicators, a univariate analysis of variance was performed; on the other hand, to assess which factors affect H-rQoL a multivariate analysis was carried out, considering p<0.05 as significant. The results are expressed as +/- 1SD. RESULTS Of the 1108 subjects enrolled in the study, 343 subjects (31.2%), including 154 males with a mean age of 44.9 +/- 14.9 years, filled in the SF-36 questionnaire. A BMI within the normal range corresponds to a more satisfactory metabolic (p<0.05) and QoL (p=0.001) picture. Age (p<0.001), presence of previous CV disorders (p=0.005), the use of antihypertensive drugs (p=0.041) and physical exercise (p=0.002) correlated significantly with H-rQoL values. CONCLUSIONS Health condition and perception are significantly affected by a clinical situation characterized by excess weight.

Abstract
We report a 19-year-old woman with minor craniofacial anomalies, mild mental retardation, and foramina parietalia permagna (FPP) (OMIM 168500). Cytogenetic analysis showed a de novo interstitial chromosome 22 long arm duplication. FISH with a panel of chromosome 22q12-q13 bands-specific BAC clones refined the cytogenetic investigation, and restricted the duplicated segment to the q12 region. Mutation analysis of FPP genes identified an insertion mutation in the ALX4 gene (344insC) in the proband and her father with loss of function of the gene. The patient's phenotype is considered in the light of the results of the cytogenetic, FISH, and molecular investigations, and her features are compared with those of other patients with similar duplications. Finally, variable phenotypic findings due to different 22q duplicated chromosomal segments are discussed. Our report indicates that 22q12 interstitial duplications are associated with craniofacial anomalies and mild mental retardation, while life threatening malformations are usually not present. Although these phenotypic changes are common and non-specific, molecular study of our patient established more precise relationships between clinical findings and 22q duplicated region(s). This approach fosters better counseling of the families of patients with newly diagnosed, similar duplications.

Abstract
We report a 19-year-old man with craniofacial dysmorphic features, anorectal malformations, eye colobomas, orthopaedic anomalies, and mild neurodevelopmental delay. Cat eye syndrome (CES) was suspected, and confirmed by cytogenetic analysis which showed the presence of a supernumerary bisatellited chromosome, identified by fluorescence in situ hybridization (FISH) as invdup(22). The marker was further analyzed with six BAC clones located at the 22q11.1 and 22q11.2 regions; this analysis allowed correct assignment at low copy repeat 4 on chromosome 22 (LCR22-4) of the two breakpoints, confirming the presence of a CES chromosome type II. The patient's phenotype is considered in the light of the cytogenetic, and FISH investigations results and other patients reported in literature. Molecular definition of the breakpoints at the LCR22-4 copy confirms the role of different chromosome 22-specific LCRs in CES chromosomes generation, as well as in other chromosome 22 germ line rearrangements. Our report confirms that, unlike other conditions, i.e. the invdup(15) bisatellited dicentric marker, the CES phenotype does not appear to correlate with the size of the marker chromosome. Additional cases are necessary to be able to draw more specific genotype-phenotype correlations and to determine the outcome of patients with CES, especially when this rare condition is diagnosed in prenatal age.

Abstract
Melanoma cells exhibit a high level of intrinsic or acquired resistance to the cytotoxic agents often associated with the over-expression of drug transporters such as P-glycoprotein (P-gp). In this in vitro study, we investigated the possible relationship between P-gp and CD44, the cell adhesion molecule involved in metastasis and tumor progression of melanoma cells. CD44 expression appeared to be similar in the parental sensitive M14 WT cells and in their resistant counterparts M14 ADR cells. Double-labeling of cryosectioned cells showed that P-gp and CD44 were transported from the synthesis loci to the cell periphery by different vesicles and began to coalesce in proximity of the plasma membrane; thus, P-gp and CD44 seemed to reach together the cell surface. Moreover, P-gp and CD44 appeared to be associated with ERM proteins. The invasive activities of both M14 WT and M14 ADR cells were analyzed by the "transwell chamber invasion" assay. M14 WT cells revealed low capacity to traverse the filters, both in the absence (motility) and in the presence (invasion) of a Matrigel coating. In comparison, M14 ADR cells displayed significantly higher motility and invasion. SEM observations showed that sensitive cells employed lamellar cytoplasmic extrusions to pass through the filter pores whereas resistant cells elongated along the hole through globular processes. In conclusion, the results herein reported suggest that drug resistance in melanoma cells appears associated with a more aggressive behaviour. P-gp and CD44 might cooperate to confer this more invasive phenotype.

Abstract
BACKGROUND Artery dissection is an unusual cause of ischemic stroke, particularly frequent among young patients. The aim of this study was to collect epidemiological data on artery dissection in a hospital-based community, set up a diagnostic protocol and discover outcome predictors. METHODS Among patients suffering from cerebral infarction resident in our country, those with clinical and radiological features suggestive of artery dissection were selected. Risk factors, investigative techniques and treatment were evaluated. Patients were subjected to clinical examinations and were regularly tested neuradiologically. RESULTS Out of 895 ischemic stroke patients, 10 patients with cervical artery dissection (1.1%) were found. Seven patients were treated with anticoagulants and 3 received antiplatelet agents. One posttraumatic artery dissection patient died within a few days of the stroke. None of the patients suffered from a recurrence, while serious disability occurred in 4 of them. CONCLUSIONS Artery dissection should be suspected in any cerebral infarction patient, especially in young patients without risk factors for cerebrovascular diseases. The treatment of choice consists of anticoagulants. An early clinical diagnosis, strongly supported by radiological tests, is mandatory to start the proper treatment and achieve the best possible outcome.

Abstract
OBJECTIVES To assess in a population of 21 fetuses diagnosed with absent pulmonary valve syndrome (APVS) the accuracy of prenatal diagnosis, the incidence of extracardiac and chromosomal anomalies and the perinatal outcome. METHODS This was a retrospective observational study of 21 fetuses with a confirmed diagnosis of APVS. All of them underwent fetal echocardiography and a detailed anatomical scan. Karyotyping was performed in 20/21 cases, with fluorescent in-situ hybridization analysis to detect the 22q11 microdeletion performed in 16/21 cases. The following variables were retrieved from databases and evaluated: indication for referral, gestational age at diagnosis, presence of cardiomegaly, branch pulmonary dilatation, associated anomalies or intrauterine growth restriction, and fetal/neonatal outcome. Autopsy reports and postnatal surgical/medical files were available for confirmation in all cases. RESULTS Prenatal diagnosis of APVS proved correct in all cases, with only three cases occurring not in association with tetralogy of Fallot. Additional cardiovascular anomalies were present in five cases (24%). Extracardiac anomalies were found in nine cases (42.8%), and were associated with chromosomal anomalies in five cases (24%). The 22q11 microdeletion was present in 4/16 cases (25%). Fetal/neonatal outcome was as follows: nine terminations of pregnancy, three intrauterine deaths, six postnatal deaths. The remaining three (14.3%) neonates were alive after surgery. Cardiomegaly and marked branch pulmonary dilatation were present in 16 and 15 cases, respectively, and were associated with bronchomalacia in virtually all cases. CONCLUSIONS APVS can be reliably diagnosed and characterized prenatally. The association with major chromosomal anomalies or 22q11 microdeletion is consistent with previous findings. The relatively poor survival rate is due to the high rate of terminations, associated genetic anomalies and bronchomalacia. Bronchomalacia is present in the overwhelming majority of cases featuring cardiomegaly and marked branch pulmonary dilatation.

Abstract
It is crucial to ensure an optimal clinical management of HCV infection in HIV-co-infected persons. The reasons for the development of guidelines on HCV-infection treatment in HIV-infected persons arise from the need for a standardised management of HIV/HCV coinfection in our Institute. The aim of these guidelines are: to clarify principles of clinical management of HCV infection in HIV-infected patients to care-providers; to improve the awareness of HIV-infected patients cared for our Institute on current management of HCV infection; to improve the quality of care on this topic. These guidelines, based on Evidence based Medicine principles, have been developed by a panel of experts, who conducted a systematic review of the literature, mainly taking into account current international recommendations. In the present document, the most frequent clinical presentation occurring in the management of HIV/HCV co-infected patients at our Institution are discussed. The adherence to present guidelines and their effectiveness at our Institution, outcome indicators will be evaluated. The present guidelines cannot entirely substitute the judgement of an expert clinician. However, adherence to these guidelines will contribute to the improvement of the standard of care of HIV/HCV-co-infected persons.

Abstract
We report the detection and molecular characterization of a rotavirus strain, 10733, isolated from the feces of a buffalo calf affected with diarrhea in Italy. Strain 10733 was classified as a P[3] rotavirus, as the VP8* trypsin cleavage product of the VP4 protein revealed a high amino acid identity (96.2%) with that of rhesus rotavirus strain RRV (P5B[3]), used as the recipient virus in the human-simian reassortant vaccine. Analysis of the VP7 gene product revealed that strain 10733 possessed G6 serotype specificity, a type common in ruminants, with an amino acid identity to G6 rotavirus strains ranging from 88 to 98%, to Venezuelan bovine strain BRV033, and Hungarian human strain Hun4. Phylogenetic analysis based on the VP7 gene of G6 rotaviruses identified at least four lineages and an apparent linkage between each lineage and the VP4 specificity, suggesting the occurrence of repeated interspecies transmissions and genetic reassortment events between ruminant and human rotaviruses. Moreover, strain 10733 displayed a bovine-like NSP4 and NSP5/6 and a subgroup I VP6 specificity, as well as a long electropherotype pattern. The detection of the rare P[3] genotype in ruminants provides additional evidence for the wide genetic and antigenic diversity of group A rotaviruses.

Abstract
A 17-year-old female patient with features of epilepsy was treated with valproic acid. Two years later, hypoglycemia and hyperinsulinemia appeared. Transabdominal ultrasonography, spiral computed tomography, and indium-111 Octreoscan were performed without positive results. Endoscopic ultrasonography identified an oval tumor in the pancreatic tail with a color Doppler hypervascular pattern. Surgical enucleation decreased levels of insulin and C-peptide within 20 min, and the patient became free of symptoms and medications.

Abstract
OBJECTIVE To assess the accuracy of prenatal diagnosis, the incidence of extracardiac and chromosomal anomalies, and the perinatal outcome in a population of fetuses with common arterial trunk (CAT). DESIGN Observational study of 23 fetuses from three referral centres with a confirmed diagnosis of CAT. All underwent fetal echocardiography, detailed anatomical scanning, and karyotyping. In 19 cases, FISH analysis was done to detect 22q11 microdeletion. The following variables were evaluated: gestational age at diagnosis, anatomical variants of the CAT, presence of extracardiac and chromosomal anomalies, pregnancy, and fetal-neonatal outcome. Necropsy reports and postnatal files were available for confirmation of the prenatal diagnosis in all cases. RESULTS The prenatal diagnosis proved correct in 23 of 24 cases, the last being pulmonary atresia with ventricular septal defect (PAVSD). A second cardiovascular anomaly was present in eight cases (34.8%); extracardiac anomalies were found in 10 (43.4%). FISH analysis showed 22q11 microdeletion in six of 19 cases (31.6%). Outcomes were as follows: eight terminations of pregnancy (34.8%), two intrauterine deaths (8.7%), five postnatal deaths (before or after surgery) (21.7%); the remaining eight neonates (34.8%) are alive and thriving after surgery (six) or awaiting surgery (two). CONCLUSIONS CAT can be reliably diagnosed and characterised in prenatal life, although differentiation from PAVSD may be challenging. The association with chromosomal anomalies is consistent (8.7%), but there is a higher risk of 22q11 microdeletion (31.6%), in agreement with postnatal studies. The relatively poor survival rate (34.8%) reflects the high rate of terminations and the unfavourable cardiac anatomy in some cases.

Abstract
AIM To evaluate the downstaging of rectal cancer after preop R +/- CT. METHODS 392 patients (pts) with rectal cancer were observed. Only 172 pts (58%) with II and III stage cancer of middle and lower third were examined. Enrol-led pts were 168: 52 of them received preop R +/- CT (32 RT, 20 R + CT). Preop R +/- CT group included 14 middle third cancers (73%), 38 lower third (17%). In this group, tumor stage was as follows: 44 T3 stage tumors (86.4%), 8 (15.4%) T4. Mean age of this group was 57 years (range 42-67). Patients received 45 Gy for 5 weeks in 25 fractions and continuous administration of 5-FU (300-500 mg/m2/die). Surgery was performed 6 weeks +/- 7 days after the therapy. RESULTS Downstaging, at least of 1 T-stage level, was detected in 45 patients (86%) (8 middle third; 32 lower third), in 5 (9.6%) (4 middle third, 1 lower third), tumor decreased to pT0N0, while in 7 (13.5%) (2 middle third, 5 lower third), there was no response. An Anterior Resection (AR) was performed in 40 patients (77%) [4 Downstaged to pT0N0 middle third cancers; 36 downstaged but with residual disease (8 middle third, 28 lower third)]; APR was performed in 12 (23%) (7 No responders patients, 1 Downstaged to pT0N0 lower third cancer, 4 downstaged but with residual disease of lower third). CONCLUSIONS Preop R +/- CT is effective in obtaining a significative downstaging to allow sphincter saving surgery, without compromising oncological results.

Abstract
Broncho-oesophageal fistulae are rare lesions and may be benign or malignant. The articles in medical literature generally concern one case of BEF, and rarely more cases. The term "benign" is debatable, considering the severity of this disease in view of the aetiology and the bronchopulmonary complications. The aetiology in the past was connected to tuberculosis or toxoplasmosis, now to bacterial, viral or fungal infections. The Authors report three acquired cases and one congenital. They confirm the importance of anamnesis, symptomatology and oesophagography for diagnosis and CT scan for detection of pulmonary lesions. The treatment is surgical with resection of fistula and suture of the oesophagus and bronchus, interposing pleura or pericardium or intercostal muscle.

Abstract
PURPOSE We determine the value of dynamic sentinel node biopsy for staging squamous cell carcinoma of the penis. MATERIALS AND METHODS During a period of 2 years 17 patients with penile cancer was performed after lymphoscintigraphy pre and intraoperatively with gamma ray detection probe at biopsy of the sentinel node with the aid of perilesional administered patent blue dye. After 20 days regional lymph node dissection was performed in all patients. RESULTS Sentinel node metastasis was found in 5 patients; in one case lymphoscintigraphy not visualized sentinel node. All negative node biopsy was confirmed with the regional lymph node dissection. No major complication did occur after sentinel node biopsy. CONCLUSIONS Occult lymph node metastases can be detected by dynamic sentinel node biopsy including preoperative lymphoscintigraphy, vital dye and gamma ray detection probe with a sensitivity of 78%, predictive negative value of 100% and with low morbidity.
