RESUMO
OBJECTIVE: To determine if hemodynamic assessment in 'low-risk' pregnant women at term with an appropriate-for-gestational age (AGA) fetus can improve the identification of patients who will suffer maternal or fetal/neonatal complications during labor. METHODS: This was a prospective observational study of 77 women with low-risk term pregnancy and AGA fetus, in the early stages of labor. Hemodynamic indices were obtained using the UltraSonic Cardiac Output Monitor (USCOM® ) system. Patients were followed until the end of labor to identify fetal/neonatal and maternal outcomes, and those which developed complications of labor were compared with those delivering without complications. RESULTS: Eleven (14.3%) patients had a complication during labor: in seven there was fetal distress and in four there were maternal complications (postpartum hemorrhage and/or uterine atony). Patients who developed complications during labor had lower cardiac output (5.6 ± 1.0 vs 6.7 ± 1.3 L/min, P = 0.01) and cardiac index (3.1 ± 0.6 vs 3.5 ± 0.7 L/min/m2 , P = 0.04), and higher total vascular resistance (1195.3 ± 205.3 vs 1017.8 ± 225.6 dynes × s/cm5 , P = 0.017) early in labor, compared with those who did not develop complications. Receiver-operating characteristics curve analysis to determine cut-offs showed cardiac output ≤ 5.8 L/min (sensitivity, 81.8%; specificity, 69.7%), cardiac index ≤ 2.9 L/min/m2 (sensitivity, 63.6%; specificity, 76.9%) and total vascular resistance > 1069 dynes × s/cm5 (sensitivity, 81.8%; specificity, 63.6%) to best predict maternal or fetal/neonatal complications. CONCLUSIONS: The study of maternal cardiovascular adaptation at the end of pregnancy could help to identify low-risk patients who may develop complications during labor. In particular, low cardiac output and high total vascular resistance are apparently associated with higher risk of fetal distress or maternal complications. Copyright © 2017 ISUOG.

BACKGROUND: Hemorrhoidal disease is a common proctologic disorder. The HemorPex System(®) (HPS) (Angiologica, S. Martino Siccomario PV, Italy) is an innovative surgical technique based on muco-hemorrhoidopexy without Doppler guidance. The aim of this study was to evaluate the efficacy of HPS in on the treatment of grade II and III hemorrhoids. METHODS: One hundred patients with grade II and III hemorrhoidal disease were included in the study and operated on using HPS without Doppler guidance. The procedure consists of a mucopexy carried out by means of a dedicated rotating anoscope in the 6 relatively constant positions of the terminal branches of the superior hemorrhoidal artery. A direct follow-up was carried out on 100 patients for up to 3 months. A late analysis (>12 months postoperatively) was conducted by telephone interview. At follow-up the following parameters were considered: pain, bleeding, prolapse, difficulties with hygiene and patient satisfaction with treatment. RESULTS: Operative time was 16 ± 5 min. Three-month follow-up showed significant improvement of symptoms: pain was present in 10 (10 %) patients versus 45 (45 %) preoperatively; bleeding in 13 (13 %) of patients versus 57 (57 %) preoperatively; prolapse in 13 (13 %) of patients versus 45 (45 %) preoperatively and difficulties with hygiene in 1 (1 %) versus 24 (24 %) preoperatively (all p < 0.05). At longer follow-up which was available in 67 patients, 5 patients (7.5 %) had recurrence and were reoperated on at 8, 10, 24, 26 and 36 months, respectively after the first procedure. As regards patient satisfaction, complete satisfaction was reported by 95/100 patients (95 %) at 3 months, 62/67 (92.5 %) at 12 months and 8/56 (85.7 %) at 24 months; partial satisfaction was reported by 3/100 patients (3 %) with intermittent bleeding at 3 months, 3/67 (4.4 %) patients at 12 months and 6/56 (10.7 %) patients at 24 months, all with either intermittent bleeding or prolapse. Dissatisfaction with the procedure was reported by in 1/100 (1 %) patient at 3 months, 2/67 (2.9 %) at 12 months and 2/56 (3.6 %) at 24 months including patients who underwent reintervention. CONCLUSIONS: HPS can be used in the treatment of grade II and III hemorrhoidal disease. Our results show that this simple technique may be an effective but due to the important limitations of this study (loss to follow-up, non-comparative study) further studies are required.

abstract: Primary synovial chondromatosis of the hip is a rare joint condition characterized by the abnormal proliferation of cartilaginous tissue within the synovial membrane, which leads to the formation of clusters of chondrocytes floating in the joint space. This commentary provides a comprehensive overview of the pathology, including symptoms, diagnosis, treatment options and long-term management. Patients with primary synovial chondromatosis complaint pain and functional impairment, together with a peculiar joint popping sensation during movement, so determining early disability. The early treatment can lead to better clinical outcomes, with increased preservation of joint function and reduced risk of long-term disability, but strictly depend on symptoms acknowledgement and proper imaging interpretation. As a chronic pathology, surgical approach must necessarily be part of a larger medical and rehabilitative care planning, with long period follow-up. Multidisciplinary team management, with the active involvement of the patient is pivotal in improving the clinical outcomes and quality of life.

BACKGROUND: The aim of the treatment of radial head comminuted fractures is the restoration of anatomical normalcy to avoid the risk of several complications such as joint instability. Among the options for the treatment of such fractures, it is worth mentioning osteosynthesis, resection of the radial head or prosthetic replacement. In the presence of comminution or severe dislocation of the fracture's fragments, as in our patient's type III Mason fracture, prosthesis implantation is the treatment of choice. CASE REPORT: This clinical case reports a 22-year-old volleyball player, who during training suffered a comminuted fracture of the radial head, type III according to Mason's classification. A prosthesis was implanted. The post-operative course took place regularly. However, approximately three months after surgery, the patient experienced sudden pain and functional limitation following a normal elbow extension movement, so much so that he required medical attention in our emergency room. Following all the appropriate clinical-instrumental tests, a complete dissociation of the bipolar prosthesis of the radial head was found. CONCLUSIONS: Our clinical case shows the disassembly of a bipolar radial head prosthesis, a rather rare complication. From a medicolegal perspective, the patients should be aware of the increased risk of requiring further surgery after radial head replacement. When patients are thoroughly informed, they can cooperate and comply with indications more effectively, thus taking an active role in recovery management.

BACKGROUND: Through different pharmacodynamic-kinetic interactions, weekly administration of proved efficacy agents can overcome resistance with lower toxicity and greater benefit. Based on this assumption, we designed a phase I-II trial with weekly non-pegylated liposomal anthracycline and taxane in first-line breast cancer patients. PATIENTS AND METHODS: We enrolled 56 previously untreated metastatic breast cancer patients; they were randomly assigned to receive paclitaxel (Taxol) (50 mg/mq) or docetaxel (Taxotere) (30 mg/mq) combined with non-pegylated liposomal anthracycline (25 mg/mq) on days 1, 8 and 15 every 4 weeks. The primary end points were the clinical benefit and treatment-related toxic effects assessment. Secondary end points were time-to-disease progression (TTP) and overall survival (OS). RESULTS: The overall clinical benefit was 87.04%. World Health Organization G3-4 toxic effects included neutropenia (45%), anemia (44%), complete alopecia (83%), severe onycholysis and neuropathy. The 24% of patients developed left ventricular ejection fraction reduction but none >10% with recover after treatment completion. The median absolute decrease from baseline was 1%. Median TTP was 11 months and median OS was 23 months. CONCLUSIONS: Combined weekly administration of taxane and non-pegylated liposomal anthracycline is well tolerated and clinical benefit data encourage phase III study design.

BACKGROUND: Dihydroxyphenylacetaldehyde (DOPAL), a cytotoxic metabolite of dopamine, is the focus of the 'catecholaldehyde hypothesis' about the pathogenesis of Parkinson disease. This study explored whether DOPAL is detectable in human striatum - especially in the putamen (Pu), the main site of dopamine depletion in Parkinson disease - and is related to other neurochemical indices of catecholamine stores and metabolism in Parkinson disease. METHODS: Putamen, caudate (Cd), and frontal cortex (Ctx) catechols were measured in tissue from patients with pathologically proven end-stage Parkinson disease (N=15) and control subjects (N=14) of similar age with similar post-mortem intervals. RESULTS: Putamen DOPAL (3% of dopamine in controls) correlated with dopamine and dihydroxyphenylacetic acid both across all subjects and within the Parkinson disease and control groups. Pu dopamine was decreased by 93% and dihydroxyphenylacetic acid 95% in Parkinson disease vs. controls, with smaller decreases of DOPAL (83%) and norepinephrine (73%) in Pu and of dopamine (74%) and dihydroxyphenylacetic acid (82%) in Cd. In Parkinson disease, Pu DOPAL:dihydroxyphenylacetic acid averaged 3.4 times and DOPAL:dopamine 4.4 times control (P=0.03 each). The main catecholamine in Ctx was norepinephrine, which was decreased by 51% in Parkinson disease patients. CONCLUSIONS: Correlated decreases of DOPAL, dopamine, and dihydroxyphenylacetic acid in Parkinson disease reflect severe loss of Pu dopamine stores, which seems more extensive than loss of Pu norepinephrine or Cd dopamine stores. Increased Pu DOPAL:dihydroxyphenylacetic acid ratios in Parkinson disease suggest decreased detoxification of DOPAL by aldehyde dehydrogenase. Elevated levels of cytosolic DOPAL might contribute to loss of dopaminergic neurons in Parkinson disease.

Background: The current propagation models of COVID-19 are poorly consistent with existing epidemiological data and with evidence that the SARS-CoV-2 genome is mutating, for potential aggressive evolution of the disease. Objectives: We looked for fundamental variables that were missing from current analyses. Among them were regional climate heterogeneity, viral evolution processes versus founder effects, and large-scale virus containment measures. Methods: We challenged regional versus genetic evolution models of COVID-19 at a whole-population level, over 168,089 laboratory-confirmed SARS-CoV-2 infection cases in Italy, Spain, and Scandinavia at early time-points of the pandemic. Diffusion data in Germany, France, and the United Kingdom provided a validation dataset of 210,239 additional cases. Results: Mean doubling time of COVID-19 cases was 6.63 days in Northern versus 5.38 days in Southern Italy. Spain extended this trend of faster diffusion in Southern Europe, with a doubling time of 4.2 days. Slower doubling times were observed in Sweden (9.4 days), Finland (10.8 days), and Norway (12.95 days). COVID-19 doubling time in Germany (7.0 days), France (7.5 days), and the United Kingdom (7.2 days) supported the North/South gradient model. Clusters of SARS-CoV-2 mutations upon sequential diffusion were not found to clearly correlate with regional distribution dynamics. Conclusion: Acquisition of mutations upon SARS-CoV-2 spreading failed to explain regional diffusion heterogeneity at early pandemic times. Our findings indicate that COVID-19 transmission rates are rather associated with a sharp North/South climate gradient, with faster spreading in Southern regions. Thus, warmer climate conditions may not limit SARS-CoV-2 infectivity. Very cold regions may be better spared by recurrent courses of SARS-CoV-2 infection.
RESUMO
Silver nitrate, alpha-aminooxyacetic acid, and aminoethoxyvinylglycine, three potent inhibitors of ethylene synthesis and action, induced the same kind of phenovariation in the liverwort Plagiochila arctica Bryhn and Kaal (Hepaticae) as do antagonists of the synthesis of hydroxyproline-containing protein. This finding (i) supports the hypothesis that hydroxyproline-protein has a role in ethylene-mediated suppression, (ii) provides evidence that the role of ethylene in the correlative development of leafy liverwort gametophytes may be similar to its role in flowering plants, and (iii) contributes to the characterization of a morphoregulatory system that mediates cellular suppression in leafy liverworts and possibly all land plants.
RESUMO
AIMS: The locus of control theory distinguishes people (internals) who attribute events in life to their own control, and those (externals) who attribute events to external circumstances. It is used to assess self-management behaviour in chronic illnesses. Group care is a model of systemic group education that improves lifestyle behaviour and quality of life in patients with Type 1 and Type 2 diabetes. This study investigated the locus of control in Type 1 and Type 2 diabetes and the possible differences between patients managed by group care and control subjects followed by traditional one-to-one care. METHODS: Cross-sectional administration of two questionnaires (one specific for diabetes and one generic for chronic diseases) to 83 patients followed for at least 5 years by group care (27 Type 1 and 56 Type 2) and 79 control subjects (28 Type 1 and 51 Type 2) of similar sex, age and diabetes duration. Both tools explore internal control of disease, the role of chance in changing it and reliance upon others (family, friends and health professionals). RESULTS: Patients with Type 1 diabetes had lower internal control, greater fatalistic attitudes and less trust in others. Patients with either type of diabetes receiving group care had higher internal control and lower fatalism; the higher trust in others in those with Type 1 diabetes was not statistically significant. The differences associated with group care were independent of sex, age and diabetes duration. CONCLUSIONS: Patients with Type 1 diabetes may have lower internal control, fatalism and reliance upon others than those with Type 2 diabetes. Receiving group care is associated with higher internal control, reduced fatalism and, in Type 1 diabetes, increased trust in others.

AIM: To verify if Group Care, a model to manage Type 2 diabetes (T2DM) by systemic continuing group education, can be administered by nurses and dieticians under pedagogic guidance, and improve metabolic control, quality of life, Locus of Control, and insulin resistance. MATERIAL AND SUBJECTS: Twenty-five patients with non-insulin-treated T2DM were randomized to Group Care and 24 to continued habitual individual care and education delivered by a diabetes specialist and pedagogist, respectively. Six nurses and 1 dietician received training by an accredited programme, a detailed operating manual and pedagogical supervision throughout the study. Follow-up was for 2 yr and included measurements of fasting blood glucose, glycated hemoglobin (HbA1c), body mass index, waist circumference, lipids, creatinine, blood pressure, serum insulin, homeostasis model assessment (HOMA) index of insulin resistance, health behaviors, quality of life, state and trait anxiety, and Locus of Control. RESULTS: One patient on Group Care and 3 controls dropped out. At the end of study, the patients on Group Care had lower HbA1c (7.6+/-0.8 vs 8.4+/-1.3, p<0.05), insulin (18.0+/-9.6 vs 24.3+/-13.7, p<0.001), HOMA index (6.9+/-5.4 vs 9.2+/-6.6, p<0.05), and fatalistic attitude (17.2+/-5.9 vs 24.9+/-4.2, p<0.001) and better quality of life (65.0+/-11.0 vs 78.4+/-19.6, p<0.001) than controls. CONCLUSIONS: Group Care delivered by trained nurses and dietitian is associated with better outcomes than those obtained by a medically and pedagogically qualified team. It may offer a model for health operators to re-organize clinical practice and for patients to improve lifestyle and strengthen the therapeutic alliance with their carers.

BACKGROUND: Until very recently the only therapeutic alternative for the management of patients affected by gout/hyperuricemia that did not respond to a first-line treatment based on allopurinol alone or who cannot tolerate allopurinol was febuxostat, a xanthine oxidase non-purine-selective inhibitor. Lately, however, a new therapeutic alternative has become available for the management of this pathology: lesinurad, a urate transporter inhibitor. OBJECTIVE: To objective of this study was to evaluate the cost effectiveness of lesinurad/allopurinol in comparison with febuxostat as a second-line therapeutic strategy for the management of patients affected by gout and hyperuricemia that did not respond to a first-line therapy based on allopurinol alone. METHODS: A Markov model was built based on the natural history of the pathology; patients entered the model according to their level of serum uric acid concentration and flowed across it according to their response to the therapy. The analysis was carried out considering the perspective of the Italian National Health Service on a lifetime horizon and 6-month cycles. Costs and quality-adjusted life-years (QALYs) were discounted at a 3.5% yearly rate. The results of the model were expressed in terms of incremental cost-effectiveness ratio (ICER). Both a one-way and a multi-way Monte-Carlo analysis were carried out in order to check the robustness of the results achieved. RESULTS: The ICER derived from the comparison was equal to 77.53/QALY on the lifetime horizon, as there was a higher level of costs associated with the combination as compared with febuxostat (10,658.27 vs. 10,645.87, for a differential of 12.40) and a higher level of QALYs achieved (7.77 vs. 7.61, for a differential of 0.16). CONCLUSIONS: The lesinurad/allopurinol combination is recommended for the treatment of patients affected by gout/hyperuricemia in the Italian Health System as it appears to be cost effective and thus sustainable for the Italian healthcare sector.

BACKGROUND: Hepatitis C virus (HCV) is a major health issue worldwide. New generation of direct-active antiviral medications is an epoch-making turning point in the management of HCV infections. OBJECTIVE: Conducing a cost-effectiveness analysis comparing the combination of elbasvir/grazoprevir and sofosbuvir + pegylated interferon/ribavirin for the management of all HCV patients (even those in the initial stages of fibrosis). METHODS: A Markov model was built on the natural history of the disease to assess the efficacy of the alternatives. The outcomes are expressed in terms of quality adjusted life-years (QALYs) and result in terms of incremental cost-effectiveness ratio). RESULTS: Elbasvir/grazoprevir implies an expenditure of 21,104,253.74 with a gain of 19,287.90 QALYs and sofosbuvir + pegylated interferon/ribavirin implies an expenditure of 31,904,410.11 with a gain of 18,855.96 QALYs. Elbasvir/grazoprevir is thus a dominant strategy. CONCLUSION: Consideration should be given to the opportunity cost of not treating patients with a lower degree of fibrosis (F0-F2).

Objetivo: Determinar la prevalencia del trastorno de estrés postraumático (TEPT) en una muestra de médicos residentes del Hospital de Clínicas, José de San Martín, Buenos Aires, Argentina, un año después del cierre total durante la cuarentena por COVID-19. Materiales y métodos: Se administraron los siguientes cuestionarios autoadministrados: una encuesta demográfica, el cuestionario de la Escala de Trauma de Davidson y la Escala de Experiencias Disociativas (EED). Se excluyeron a los residentes de primer año de especialidades básicas, a aquellos que por su especialidad no tienen contacto con pacientes y a los médicos con licencia fueron excluidos. Resultados: La prevalencia de TEPT fue de 24.3% (n=25). Las medianas de las puntuaciones de DES fueron mayores en los participantes con puntaje positivo para TEPT en comparación con los que no lo presentaban (Mann-Whitney U:13.30, p = 0.001). Se encontraron asociaciones entre el género (X2:6.074, p = 0.013), el TEPT y el tipo de especialidad (prueba exacta de Fisher, p = 0.017). No se encontraron otras asociaciones entre las demás variables analizadas y el TEPT. Conclusion: La prevalencia del TEPT fue similar a los informes previos. Se hallaron asociaciones entre este desorden, el género y el tipo de especialidad. Estos resultados deberían llamar la atención de los sistemas de salud para establecer medidas preventivas y terapéuticas para manejar esta situación.
Objective: Determine the prevalence of posttraumatic stress disorder (PTSD) in a sample of resident doctors of the Hospital de Clínicas, José de San Martín, Buenos Aires, Argentina, one year after the total closure during the quarantine by COVID-19. Materials and Methods: The following self-administered questionnaires were dispensed: a demographic survey, the Davidson Trauma Scale questionnaire, and the Scale of Dissociative Experiences (EED). First year residents of basic specialties were excluded, those who for their specialty do not have contact with patients and licensed doctors were excluded. Results: PTSD prevalence was 24.3% (n = 25). The medium-sized ones were greater in the participants with positive score for PTSD compared to those who did not present it (Mann-Whitney U: 13.30, p = 0.001). Associations between the genre were found (X2: 6,074, p = 0.013), the PTSD and the type of specialty (Fisher's exact test, p = 0.017). No other associations were found between the other variables analyzed and the PTSD. Conclusion: The prevalence of the PTSD was similar to the previous reports. Associations between this disorder, gender and type of specialty were found. These results should draw the attention of health systems to establish preventive and therapeutic measures to handle this situation

In this study the microbiological, physical and chemical results of an investigation concerning the environmental conditions of operating theatres in 38 public hospitals of the Campania Government are presented. The analysis of the results has been made by considering specific standards suggested by national and international regulations. The results showed that 84% of the operating theatres presented normal microbiological values, in relation to the total bacterial load, while 16% did not. By considering the microclimatic monitoring 55% of the operating theatres showed normal values while 45% at least a microclimatic index did not. In relation to the concentrations of anaesthetics gases the survey pointed out that the nitrous oxides was within non prescribed environmental limits (50 ppm for N2O); while 15% of the halogenated was not in normal values.

BACKGROUND: Chronic hepatitis B is a common, progressive disease, particularly when viral replication is detected. Oral antivirals can suppress viral replication and prevent or delay the development of cirrhosis and liver-related complications. The treatments of chronic hepatitis B cannot totally cure the disease but can prevent its progression to hepatocellular carcinoma, decreasing the levels of both morbidity and mortality. To date, there are several therapies indicated by the international guidelines as first-line treatments for the management of hepatitis B; two of the most effective are those based on either tenofovir or entecavir. OBJECTIVE: The aim of this study is to evaluate the cost-effectiveness of tenofovir and entecavir in the treatment of naïve patients with chronic hepatitis B. The two treatments are compared with the "no treatment" and to one another. METHODS: The cost-effectiveness analysis was conducted using a Markov model; patients entered one of the following health states: chronic hepatitis, cirrhosis (compensated or decompensated), hepatocellular carcinoma, liver transplantation or death. The analysis was carried out from the perspective of the Italian National Health Service by considering a life-time horizon with cycles lasting 1 year and with costs and QALYs (quality-adjusted life years) discounted at a rate of 3.5%. The results of the model were analysed in terms of incremental cost-effectiveness ratio (ICER). RESULTS: ICERs for tenofovir and entecavir emerging from the comparison versus "no treatment" were equal to 10,274.73 and 16,300.44 per QALY gained, respectively, on the life-time horizon. Tenofovir was dominant in the direct comparison with entecavir, indicating more QALYs and a lower consumption of resources. The Monte Carlo simulation demonstrated that in 97% (tenofovir) and in 85% (entecavir) of the scenarios performed, the cost per QALY fell below the threshold of 30,000/QALY. The budget impact analysis showed savings for tenofovir amounting to 33% compared to entecavir in the first year on treatment and to 31% in following years. CONCLUSIONS: Entecavir and tenofovir are recommended for the treatment of patients with chronic Hepatitis B in the Italian Health System. In particular, tenofovir appeared to be the more cost-effective drug for the management of chronic hepatitis B virus (HBV) infections. These results could help decision makers and clinicians to address their decision when choosing a first-line treatment for the management of people affected by chronic HBV.

BACKGROUND: Breast cancer in patients under 40 years is uncommon. Surveillance, Epidemiology and End Results (SEER) program reveals that 75% of breast tumors occur in women age > 50 years, only 6.5% in women age < 40 years, and a mere 0.6% in women age < 30 years. Breast-conserving surgery with subsequent chemo-radiotherapy has become the treatment of choice in women with breast neoplasm. CASE REPORT: Two young patients, 30 and 28 years respectively, with breast cancer. One patient with an atypical medullary breast carcinoma diagnosis, pT2 pN1 bipMx, Grade 3 Stage IIB, negative for receptors, Ki 67: 47%, cERB-2 negative; the other with an intraductal breast carcinoma, pT1c pN0 pMx, Grade 2 Stage I, negative for receptors, Ki 67: 85%, cERB-2 negative, p53 negative, Bcl-2 negative. The first patient underwent right radical mastectomy sec. Madden and axillary lymphoadenectomy in October 2001, started six cycles of adjuvant chemotherapy and radiotherapy on the right side of the chest and on axillary and supraclavicular lymph nodes area. After 2 years an ecotomography revealed small hypoechogenic nodules in the left breast. In December the patient underwent left radical mastectomy with positioning of an expander device. The histological exam revealed a not much differentiated intraductal carcinoma, pT1a N0 Mx, Stage I. After the surgical therapy, she follows another adjuvant chemotherapy. The second patient underwent left quadrantectomy with axillary limphoadenectomy in November 2004. Like the first-will follow several cycles of adjuvant chemotherapy and radiotherapy. DISCUSSION: Breast cancer in women under 40 years of age differ from breast cancer in older women in numerous clinical, pathological and biological features. The studies demonstrate that breast cancer arising in women under 40 years have a more aggressive profile than those of older patients. In both our patients family history of breast cancer was reported. That suggests a possible genetic susceptibility of these patients through BRCA1 and BRCA2 germ-line mutations. Breast conservative surgery with chemio-radiotherapy is the most commonly used treatment breast cancer, expecially in consideration of the aggressiveness of the lesions.

The use of umbilical venous catheter (UVC) is common practice in neonatal units. The traumatic injury of the hepatic parenchyma is a rare complication. We present a case of a preterm newborn underwent ultrasound examination revealing a hyperechogenic focal lesion at the confluence of the hepatic veins This finding, according to patient's history, was suspected to be a traumatic injury of the liver parenchyma caused by umbilical catheterization. During sonographic follow-up this lesion gradually reduced until complete resolution. Finally, when focal hyperechogenic hepatic lesion is incidentally detected in newborn with history of UVC placement, the radiologists must consider the traumatic etiology.

BACKGROUND AND PURPOSE: T2-weighted FLAIR can be combined with 3D-FSE sequences with isotropic voxels, yielding higher signal-to-noise ratio than 2D-FLAIR. Our aim was to explore whether a T2-weighted FLAIR-volume isotropic turbo spin-echo acquisition sequence (FLAIR-VISTA) with fat suppression shows areas of abnormal brain T2 hyperintensities with better conspicuity in children than a single 2D-FLAIR sequence. MATERIALS AND METHODS: One week after a joint training session with 20 3T MR imaging examinations (8 under sedation), 3 radiologists independently evaluated the presence and conspicuity of abnormal areas of T2 hyperintensities of the brain in FLAIR-VISTA with fat suppression (sagittal source and axial and coronal reformatted images) and in axial 2D-FLAIR without fat suppression in a test set of 100 3T MR imaging examinations (34 under sedation) of patients 2-18 years of age performed for several clinical indications. Their agreement was measured with weighted κ statistics. RESULTS: Agreement was "substantial" (mean, 0.61 for 3 observers; range, 0.49-0.69 for observer pairs) for the presence of abnormal T2 hyperintensities and "fair" (mean, 0.29; range, 0.23-0.38) for the comparative evaluation of lesion conspicuity. In 21 of 23 examinations in which the 3 radiologists agreed on the presence of abnormal T2 hyperintensities, FLAIR-VISTA with fat suppression images were judged to show hyperintensities with better conspicuity than 2D-FLAIR. In 2 cases, conspicuity was equal, and in no case was conspicuity better in 2D-FLAIR. CONCLUSIONS: FLAIR-VISTA with fat suppression can replace the 2D-FLAIR sequence in brain MR imaging protocols for children.

Child maltreatment is a complex life experience occurs when a parent or caregiver does an intentional or potential damage to a child, including acts of commission and omission. Child abuse is not an uncommon event, but it is not always recognized. Identifying the real number of maltreated children is a challenge because of the large variability in reported prevalence data across studies. Unfortunately, in the United States, it affects 1 in 8 children, by the age of 18 years, annually. Paediatricians may encounter a variety of forms of maltreatment such as neglect, emotional, physical and sexual abuse. These aspects should be recognised, examined and evaluated by employing a systematic approach and focusing on basic needs of children that may not be met. Child maltreatment is a global problem with serious life-long physical and psychological or psychiatric outcomes. It is associated with important economic and social costs (such as physical and mental health, productivity losses, child welfare, criminal justice and special education costs) due to its high prevalence and its long-term and short-term consequences. In the United States, the average cost of nonfatal maltreatment is $210,012 per children and the cost of fatal maltreatment is $1,272,900. General Practitioners are quite prepared to face the problem of child maltreatment: since they have the opportunity to meet several members of the same family, they can detect stressors that put children at risk of maltreatment. All health professionals have the responsibility to protect children from abuse and neglect.

The Met tyrosine kinase - the HGF receptor - induces cell transformation and metastasis when constitutively activated. Met signaling is mediated by phosphorylation of two carboxy-terminal tyrosines which act as docking sites for a number of SH2-containing molecules. These include Grb2 and p85 which couple the receptor, respectively, with Ras and PI 3-kinase. We previously showed that a Met mutant designed to obtain preferential coupling with Grb2 (Met2xGrb2) is permissive for motility, increases transformation, but - surprisingly - is impaired in causing invasion and metastasis. In this work we used Met mutants optimized for binding either p85 alone (Met2xPI3K) or p85 and Grb2 (MetPI3K/Grb2) to evaluate the relative importance of Ras and PI 3-kinase as downstream effectors of Met. Met2xPI3K was competent in eliciting motility, but not transformation, invasion, or metastasis. Conversely, MetP13K/Grb2 induced motility, transformation, invasion and metastasis as efficiently as wild type Met. Furthermore, the expression of constitutively active PI 3-kinase in cells transformed by the Met2xGrb2 mutant, fully rescued their ability to invade and metastasize. These data point to a central role for PI 3-kinase in Met-mediated invasiveness, and indicate that simultaneous activation of Ras and PI 3-kinase is required to unleash the Met metastatic potential.
