Abstract
Background Endoscopy is an important tool in assessing the severity of gastrointestinal diseases including Eosinophilic Esophagitis (EoE). Agreement regarding endoscopy outcomes is important when using tools such as the Endoscopic Reference Score for EoE (EREFS). Purpose Our goal was to determine interrater and intrarater agreement of EREFS among Canadian pediatric gastroenterologists. Method Survey-based study of interrater and intrarater reliability amongst pediatric gastroenterologists with interest in pediatric EoE. Participants were sourced from the Canadian Pediatric EoE Network. Participants were asked how many years of training they’ve had with endoscopy for pediatric EoE and their comfort in disease scoring for pediatric EoE. Pediatric EoE cases were identified from the pediatric EoE registry at the Stollery Children’s Hospital with an endoscopic video associated with each case. Participants were asked to score each video using the EREFS questionnaire for the proximal, middle and distal segments of the esophagus. 15 endoscopic videos were evaluated, with 3 cases provided each week over a period of 5 weeks. Additional data included ratings of the video quality and endoscopy quality. Of 15 cases, 12 were unique cases, distributed evenly in severity between no active disease to severe disease. 3 cases were repeated to assess intrarater reliability. The maximum grade of the proximal, middle and distal segments of the esophagus for each component endoscopic finding (edema, rings, exudates, furrows, strictures) were used for reliability calculations. Fleiss Kappa was calculated for all EREFS items and for each component endoscopic finding. Cohen’s Kappa was calculated to assess intrarater reliability. Result(s) Fifteen participants were recruited for the study. The participants had a median of 12 years (IQR: 7, 19) of clinical experience in endoscopy for pediatric EoE. The majority of participants were “comfortable” (i.e., 4 on 5-point scale) with EREFS scoring for pediatric EoE. Fleiss Kappa for all EREFS items was 0.481. For each component endoscopic finding (edema, rings, exudates, furrows, strictures), Fleiss Kappa was 0.365, 0.293, 0.548, 0.263, 0.445 respectively. Cohen’s Kappa had a median of 0.620 (IQR: 0.593, 0.704). The majority of raters rated video quality and endoscopy quality as “good” (i.e., 4 on 5-point scale). Conclusion(s) There is moderate interrater reliability in EREFS scoring for pediatric EoE. Interrater reliability was between fair to moderate for each component endoscopic finding. Intrarater reliability was good. This study shows there is room for improvement in disease scoring for pediatric EoE. This could be in the form of additional training, expert-defined conventions, or centralized reading which have reduced variability in endoscopic reporting for adult GI disease in past studies and could be used in a follow-up study to attempt to improve agreement. Additionally, incorporating EREFS into routine clinical practice may increase agreement amongst endoscopists.

Abstract
BACKGROUND Legg-Calvé-Perthes (LCP) is a common orthopedic childhood disease that causes a deformity of the femoral head and to an adaptive deformity of the acetabulum. The altered joint biomechanics can result in early joint degeneration that requires total hip arthroplasty. In 2002, Ganz et al. introduced the femoral head reduction osteotomy (FHRO) as a direct joint-preserving treatment. The procedure remains one of the most challenging in hip surgery. Computer-based 3D preoperative planning and patient-specific navigation instruments have been successfully used to reduce technical complexity in other anatomies. The purpose of this study was to report the first results in the treatment of 6 patients to investigate whether our approach is feasible and safe. METHODS In this retrospective pilot study, 6 LCP patients were treated with FHRO in multiple centers between May 2017 and June 2019. Based on patient-specific 3D-models of the hips, the surgeries were simulated in a step-wise fashion. Patient-specific instruments tailored for FHRO were designed, 3D-printed and used in the surgeries for navigating the osteotomies. The results were assessed radiographically [diameter index, sphericity index, Stulberg classification, extrusion index, LCE-, Tönnis-, CCD-angle and Shenton line] and the time and costs were recorded. Radiologic values were tested for normal distribution using the Shapiro-Wilk test and for significance using Wilcoxon signed-rank test. RESULTS The sphericity index improved postoperatively by 20% (p = 0.028). The postoperative diameter of the femoral head differed by only 1.8% (p = 0.043) from the contralateral side and Stulberg grading improved from poor coxarthrosis outcome to good outcome (p = 0.026). All patients underwent acetabular reorientation by periacetabular osteotomy. The average time (in minutes) for preliminary analysis, computer simulation and patient-specific instrument design was 63 (±48), 156 (±64) and 105 (±68.5), respectively. CONCLUSION The clinical feasibility of our approach to FHRO has been demonstrated. The results showed significant improvement compared to the preoperative situation. All operations were performed by experienced surgeons; nevertheless, three complications occurred, showing that FHRO remains one of the most complex hip surgeries even with computer assistance. However, none of the complications were directly related to the simulation or the navigation technique.

Abstract
AIM To evaluate the diagnostic accuracy achieved from a fat-water Dixon sequence alone compared to a combination of a silicone-specific magnetic resonance imaging (MRI) sequence and a water-specific MRI sequence in the assessment of breast implants. MATERIALS AND METHODS In this institutional review board (IRB)-approved study the integrity of breast implants was assessed retrospectively in 27 patients undergoing breast MRI at 3 T. A qualitative evaluation of (set 1) a silicon-selective water-saturated short tau inversion recovery (STIR) sequence in combination with a water-only Dixon dataset (total acquisition time 7 minutes 17 seconds), and of (set 2) fat-only and water-only Dixon datasets (4 minutes 8 seconds) was performed by two readers independently evaluating the following features: margin definition of the implant, water suppression homogeneity, image quality, presence of artefacts and their effects on the imaging interpretation, and diagnostic confidence. Diagnostic accuracy in implant rupture detection was determined and either surgical confirmation or diagnosis from the radiological report was used as a standard of reference. RESULTS In both sequences, margin definition of the implant wall, water suppression homogeneity, and overall image quality were rated good-excellent in most of cases. Water suppression homogeneity was moderate-poor in a greater number of cases in set 1. Movement artefacts were more frequent in set 1 whereas five cases (18.5%) exhibited swap artefacts between silicone and water in set 2. Diagnostic confidence was rated high-very high with both sequences in most of cases. Diagnostic accuracy was 100% for both readers using set 1 and 96.2% and 100% using set 2. CONCLUSION A single Dixon sequence allows an accurate diagnostic evaluation of breast implants and concomitant shortening of the overall acquisition time.

Abstract
Abstract
BACKGROUND: Celiac disease (CD) is a digestive disease that is caused by an immune reaction to the protein gluten. The gluten free diet (GFD) is the only treatment for CD. In 2012, the sale of GF processed foods reached up to $460million in Canada; an increase in 25% since 2008. Despite being the fastest growing food intolerance category in Canada, GFD consumers face challenges from various voluntary GF-labelling schemes and limited retail and food-service product options.
OBJECTIVES: To estimate GF-food expenditure patterns for affected families with children or adolescents with CD to identify the cost burden of following a GFD and compared against non-GFD Canadian families.
DESIGN/METHODS: A pilot study was conducted in families with a child with biopsy proven CD following the GFD (n=15; 10±3 years) and attending a GI/CD clinic. Family Socio-demographics (age of parents, number of children/number of members following GFD in households) and the receipts of food purchases over a one-month period were obtained from parents/caregivers. The cost of GFD was analyzed as “actual food costs on related receipts” and determined as total GFD cost (per household/per child with CD) basis. The result of this study was compared against average incomes and food expenditures of Canadian households as reported by Statistic Canada in 2013.
RESULTS: The mean age of the parents of child with CD was (44±5 years) and the mean number of children in households was 2.0±0.6. The average duration of following GFD was 4±2 years (age at diagnosis 6±2 years). The median income for Canadian family and for family with children with CD was C$ 84,000/year and C$ 100,000/year, respectively. The average food expenditure was C$ 842/month for the average Canadian household with children vs C$ 1105±393/month for comparable Canadian households affected by CD. The amount of money spent on GF packaged foods was C$ 145±100/month. The average food expenditure of GF food and gluten containing food was C$112±72/child/month (+GF) and C$ 29±14/house-hold member/month (-GF), respectively.
CONCLUSION: Total food expenditures in families with a child/adolescent with CD are higher than the Canadian averages. This has implications on economic access and adherence to GFD in children/adolescents with CD. CD and proper dietary adherence to GFD guidelines poses significant economic burdens on affected families. These results and unanswered questions of economic access, affordability and quality of life hold several Canadian policy implications.

Abstract
BACKGROUND AND PURPOSE Normative age-related decline in paravertebral muscle quality is important for reference to disease and risk identification in patients. We aimed to establish age- and vertebral level-dependence of paravertebral (multifidus and erector spinae) muscle volume and fat content in healthy adult volunteers. MATERIALS AND METHODS In this prospective study multifidus and erector spinae fat signal fraction and volume at lumbar levels L1-L5 were measured in 80 healthy volunteers (10 women and men per decade, 20-62 years of age) by 2-point Dixon 3T MR imaging. ANOVA with post hoc Bonferroni correction compared fat signal fraction and volume among subgroups. Pearson and Spearman analysis were used for correlations (P < .05). RESULTS Fat signal fraction was higher in women (17.8% ± 10.7%) than men (14.7% ± 7.8%; P < .001) and increased with age. Multifidus and erector spinae volume was lower in women (565.4 ± 83.8 cm(3)) than in men (811.6 ± 98.9 cm(3); P < .001) and was age-independent. No differences in fat signal fraction were shown between the right and left paravertebral muscles or among the L1, L2, and L3 lumbar levels. The fat signal fraction was highest at L5 (women, 31.9% ± 9.3%; men, 25.7% ± 8.0%; P < .001). The fat signal fraction at L4 correlated best with total lumbar fat signal fraction (women, r = 0.95; men, r = 0.92, P < .001). Total fat signal fraction was higher in the multifidus compared with erector spinae muscles at L1-L4 for both sexes (P < .001). CONCLUSIONS Lumbar paravertebral muscle fat content increases with aging, independent of volume, in healthy volunteers 20-62 years of age. Women, low lumbar levels, and the multifidus muscle are most affected. Further study examining younger and older subjects and the functional impact of fatty infiltrated paravertebral muscles are warranted.

Abstract
Proteins are important targets of several modifications caused by oxidative stress, leading to structural changes and consequently partial or total loss of their functions. The oxidized proteins include advanced oxidation protein products (AOPP) derived from oxidation-modified albumin, as well as fibrinogen and lipoproteins. An increase in AOPP levels indicates an oxidative stress state and the presence of coexisting inflammation. Several investigations have also suggested an association between high AOPP levels and aging-related diseases. However, the link between elevated AOPP levels and elderly mortality risk has not yet been investigated. Here, we report on a 5-year longitudinal study that investigated the potential association between AOPP levels and mortality using a population-based representative sample of riparian elders living in Brazilian Amazon region (Maués-AM). Age, sex, socioeconomic and cultural conditions, chronic morbidities, polypharmacy, and previous morbidities were also tested as potential confounders. The AOPP levels were measured in 540 (84.78%) individuals, all of whom were followed over a 5-year period in order to establish the mortality rate. Within this study period, 74 (13.7%) elders died and 466 (86.3%) survived. The AOPP levels were higher among the elders who died within the 5-year period (46.27 ± 40.6 mmol/L) compared with those who survived (36.79 ± 20.84 mmol/L) (p = 0.002). The analysis confirmed the link between high AOPP levels and mortality risk, independent of other intervenient factors. These results suggest that elevated AOPP levels could be used to predict mortality risk in elderly patients.

Abstract
Diet treatment characterized by a reduction in or a selection of food proteins is currently suggested in hepatic encephalopathy. This article is a review of the present knowledge about the characteristics and the rationale of vegetarian diets in cirrhotic patients with overt or latent encephalopathy. In addition, evidence relating diet and encephalopathy and the nutritional features and needs of cirrhotic patients is reported. Finally, the rationale of a diet based on vegetable and milk-derived proteins that may overcome the limits and the possible adverse effects of a strict vegetarian diet is presented.

Abstract
OBJECTIVES The aim of this study was to examine the pharmacokinetics of orally administered omeprazole in children. METHODS Plasma concentrations of omeprazole were measured at steady state over a 6-h period after administration of the drug. Patients were a subset of those in a multicenter study to determine the dose, safety, efficacy, and tolerability of omeprazole in the treatment of erosive reflux esophagitis in children. Children were 1-16 yr of age, with erosive esophagitis and pathological acid reflux on 24 h-intraesophageal pH study. The "healing dose" of omeprazole was that at which subsequent intraesophageal pH study normalized. Children remained on this dose for 3 months, and during this period the pharmacokinetics were measured. RESULTS A total of 57 children were enrolled in the overall healing phase of the study. Pharmacokinetic study was optional for subjects and was performed in 25 of the 57 enrolled. The doses of omeprazole required were substantially higher doses per kilogram of body weight than in adults. Values of the pharmacokinetic parameters of omeprazole were generally within the ranges previously reported in adults. However, the plasma levels, area under the plasma concentration versus time curve (AUC), plasma half-life (t(1/2)), and maximal plasma concentration (Cmax), were lower in the younger age group, when the AUC and Cmax were normalized to a dose of 1 mg/kg. Furthermore, within the group as a whole, these values showed a gradation from lowest in the children 1-6 yr of age to higher in the older age groups. CONCLUSIONS The pharmacokinetics of omeprazole in children showed a trend toward higher metabolic capacity with decreasing age, being highest at 1-6 yr of age. This may explain the need for higher doses of omeprazole on a per kilogram basis, not only in children overall compared with adults but, in many cases, particularly in younger children.

Abstract
Chronic recurrent multifocal osteomyelitis (CRMO) is a rare disease of children characterized by aseptic inflammation of the long bones and clavicles. No infectious etiology has been identified, and CRMO has been associated with a number of autoimmune diseases (including Wegener's granulomatosis and psoriasis). The relationship between CRMO and inflammatory bowel disease is poorly described. Through an internet bulletin board subscribed to by 500 pediatric gastroenterologists, we identified six inflammatory bowel disease patients (two with ulcerative colitis, four with Crohn's colitis) with confirmed CRMO. In all cases, onset of the bony lesions preceded the onset of bowel symptoms by as much as five years. Immunosuppressive therapy for the bowel disease generally resulted in improvement of the bone inflammation. Chronic recurrent multifocal osteomyelitis should be considered in any inflammatory bowel disease patient with unexplained bone pain or areas of uptake on bone scan. CRMO may be a rare extraintestinal manifestation of inflammatory bowel disease; alternatively, certain individuals may be genetically predisposed to the development of both diseases.

Abstract
We sought to determine, in a piglet model, whether severe sugar malabsorption causes colonic injury or inflammation. Twenty-four piglets were randomized to receive either control formula (CON) or CON supplemented with lactulose (LAC) (N = 12 each group). After seven days, inflammation, apoptosis, and crypt cell proliferation were assessed in the proximal colon (cecum). Lactulose feeding caused persistent diarrhea. In both groups, breath H2 concentration was low, suggesting no increased fermentation in the LAC group. Weight gain/volume formula intake was identical in the CON and LAC groups (0.09+/-0.13 and 0.09+/-0.11 g/ml) respectively. Injury to the colon did not occur, but inflammation of the colon (scale 0-5) was greater in LAC (score of 1.5+/-1.38) than in CON (0.42+/-0.79; P<0.05). Cell proliferation at the basal 40% of the crypt was 92% increased in CON (labeling index 22.8+/-9.9 vs. 11.9+/-2.8; P<0.05).

Abstract
Dysphagia in motor neuron disease (MND) may lead to dangerous complications such as cachexia and aspiration pneumonia. Functional evaluation of the oropharyngeal tract is crucial for identifying specific swallowing dysfunctions and planning appropriate rehabilitation. As part of a multidisciplinary study on the treatment of dysphagia in patients with neuromuscular diseases, 23 MND patients with different degrees of dysphagia underwent videofluoroscopy, videopharyngolaryngoscopy and pharyngo-oesophageal manometry. The results of the three instrumental investigations were analysed in order (1) to define the pattern of swallowing in MND patients complaining of dysphagia; (2) to evaluate whether subclinical abnormalities may be detected; and (3) to assess the role of videofluoroscopy, videopharyngolaryngoscopy and manometry in the evaluation of MND patients with deglutition problems. Correlations between the instrumental findings and clinical features (age of the patients, duration and severity of the disease, presence and degree of dysphagia) were also assessed. The results of our study showed that: (1) The oral phase of deglutition was compromised most often, followed by the pharyngeal phase. (2) In all patients without clinical evidence of dysphagia, subclinical videofluoroscopic alterations were present in a pattern similar to that found in the dysphagic group. (3) Videofluoroscopy was the most sensitive technique in identifying oropharyngeal alterations of swallowing. Impairment of the oral phase, abnormal pharyngo-oesophageal motility and incomplete relaxation of the upper oesophageal sphincter were the changes most sensitive in detecting dysphagia. Videofluoroscopy was also capable of detecting preclinical abnormalities in non-dysphagic patients who later developed dysphagia. Practical guidelines for the use of instrumental investigations in the assessment and management of dysphagia in MND patients are proposed.

Abstract
Alteration of the pharyngoesophageal musculature is a common finding in patients with myotonic dystrophy (MD), regardless of the presence of dysphagia. The aim of the present study was to determine whether a specific pattern of swallowing abnormalities could be identified in MD patients, and the possible correlation with the size of CTG repeats. Fifteen MD patients, 8 of whom were asymptomatic for dysphagia, underwent a videofluoroscopic study of swallowing. Alterations of the pharyngoesophageal phase of swallowing were detected in 12 of 15 patients, 6 without clinical evidence of dysphagia. Incomplete relaxation of the upper esophageal sphincter (UES) and esophageal hypotonia were the most common alterations. We found a significant correlation between the number of radiological alterations and the size of CTG repeats. A typical radiological pattern of swallowing has also been identified. The role of videofluoroscopy in evaluation of MD patients is briefly discussed.

Abstract
To investigate pharyngeal and esophageal motor function in myotonic dystrophy (MD), and its relationship to esophageal symptoms, we used low-compliance, high-fidelity esophageal manometry and videofluorography to evaluate 14 consecutive MD patients. Patients exhibited a consistent, typical motor pattern, involving a marked reduction in resting tone of both the upper and lower esophageal sphincters, and a reduction in contraction pressure in the pharynx and throughout the esophagus. Radiology showed hypotonic pharynx with stasis and a hypo- or amotile, often dilated, esophagus. These findings were nonspecific, however, being present in patients both with and without dysphagia, which suggests that MD patients have valid compensatory mechanisms. Dysphagia only correlated to the pharyngeal impairment at manometry. Furthermore, the results of our study suggest that not only the proximal, striated part of the gullet, but also the distal part (in which smooth muscle dominates) is involved in the disease. The latter leads to the impairment of the LES resting tone and competence, highlighting the risk of gastroesophageal reflux disease in these patients.

Abstract
Recent epidemiological surveys indicated that the rate of morbidity and mortality from motor neuron disease (MND) has increased worldwide. We evaluated whether the incidence of the disease has also changed in Padua, Italy, using a retrospective method to study all MND cases hospitalized in the Padua district from 1980 to 1991. As in other regions of the world, we also found an increased incidence of the disease.

Abstract
A 15 year-old girl with insulin dependent diabetes mellitus of 11 years duration developed severe neuropathy involving the bladder and stomach. The bladder recovered after 2 months of intermittent catheterization. Metoclopramide relieved the gastric symptoms. Gastric emptying was normal after 2 further months of treatment. The neuropathy developed in spite of a mean HbA1c of 7.4% suggesting that factors in addition to glycemic control play a role in the development of the complications of insulin dependent diabetes mellitus.

Abstract
This study was aimed at investigating the effectiveness of Magnetic Resonance Imaging (MRI) in the diagnosis of perianal fistulas, by comparing imaging findings with those provided by rectal examination (RE) or surgery. The present data refer to 20 patients with anorectal fistulas in whom 24 main fistulous tracks were found. The fistulas were classified according to Parks and Kennedy's criteria, based on their relationship to the sphincters. In the 15 surgical patients, 15 of 17 fistulas were correctly identified by MRI (88.2%). In one case the submucous path of the fistula was missed, while another patient was misdiagnosed as having an intersphincter fistula which turned out to be a transphincter one at surgery. In the 5 non-surgical patients, only 4 of 7 MR-detected tracks were identified at RE. An intersphincter fistula was missed on rectal examination but demonstrated by both MRI and endoscopy. A suprasphincter track in a patient who was initially asymptomatic and thereafter developed a perianal abscess, was missed at clinics but became apparent on MR images. In one case anorectal examination underestimated the extent of the fistulous track, which was thought to be low while MRI demonstrated it to be high. Twelve abscesses were seen on MR images, all of them classified at surgery. One posterior pararectal suppurative collection in a non-surgical patient was apparent only at MRI. In our experience, in agreement with the latest literature reports, MRI has proved to be a very reliable method in the assessment of anorectal inflammatory diseases. We believe that MRI may play a valuable role in the preoperative assessment of the complex conditions causing a high risk of recurrence or anal incontinence as a result of inadequate treatment.

Abstract
We evaluated 20 patients with prostatic carcinoma who subsequently underwent radical prostatectomy with pelvic lymphadenectomy. All patients were examined with CT scan (CT) and magnetic resonance (MR) and the findings compared with definitive pathological stage. The neoplasia was correctly diagnosed in 19/20 patients with MR, but in no-one with CT. Sensitivity and diagnostic accuracy of CT and MR were respectively: for capsular penetration 15%/20% and 36.8%/40%; for seminal vesicle involvement 20%/60% and 60%/80%; bladder involvement 25%/85% and 50%/90%; nodal involvement 0%/60% and 16.6%/65%. MR seems to be more reliable than CT in detecting seminal vesicle involvement. Nevertheless, neither MR nor CT gave an adequate evaluation of capsular penetration or tumour spread to lymph nodes.

Abstract
Uveitis may be an asymptomatic ocular process when it occurs in association with chronic inflammatory bowel disease (IBD). However, the frequency of uveitis in pediatric IBD is not known, as few patients have eye examinations on a routine basis. Experience with a child with Crohn's disease, who had asymptomatic uveitis identified by routine screening initiated because of associated arthritis, prompted us to undertake this evaluation. The purpose of this cross-sectional prospective study was to ascertain the point-prevalence of uveitis in pediatric IBD patients, including 97 with Crohn's disease and 50 with ulcerative colitis. Each child underwent an ophthalmologic assessment, including slit-lamp examination. In Crohn's disease, inflammatory cells and/or flare were observed in the anterior chamber of six (6.2%) patients. These changes were mild in all six patients and required no treatment. In the group with ulcerative colitis, there were no cases of asymptomatic uveitis. There was a higher frequency of asymptomatic transient uveitis in patients with Crohn's colitis (four of 22, 18.2%) than in those of other anatomic subgroups (two of 75, 2.7%; p < 0.05). Frequency of uveitis was also higher in IBD patients having other extraintestinal manifestations (15.0%) than in those without (3.1%; p < 0.10). There was no relationship observed between the activity of bowel disease and presence of ocular inflammation.

Abstract
Pharmacologic agents effective in the treatment of Crohn's disease confined to the small intestine are limited. The therapeutic efficacy of oral mesalazine in small bowel inflammation, although theoretically promising, remains unproven. In an open-labeled initial trial, timed-release 5-aminosalicylic acid (5-ASA), administered at a daily dosage of 30.6 +/- 9.0 mg/kg (mean +/- SEM) to children with active Crohn's disease involving the small intestine, was associated with improvement on the Harvey index in six of 12 patients treated for 8.1 +/- 3.9 weeks. In a subsequent prospective, double-blind study 14 children, ages 9.3 to 16.1 years, with active Crohn's disease limited radiologically in the small intestine were randomized to receive either timed-release 5-ASA [50 mg/kg/day (maximum 3 g/day)] or placebo for 8 weeks. Following a 4-week washout period, patients crossed over to receive the other study drug for a further 8 weeks. Six children completed the entire 20-week trial. The van Hees index improved among patients receiving 5-ASA for 8 weeks (delta = -18 +/- 6.4) but deteriorated among patients given placebo (delta = +14 +/- 4.1) (p < 0.05). Mean Crohn's Disease Activity Index (CDAI) decreased marginally after 8 weeks of 5-ASA treatment (delta = -48 +/- 38.2) but not with placebo (delta = -3.0 +/- 7.9) (p = 0.31). Of the eight noncompleters, more patients dropped out of the study because of lack of therapeutic response to placebo (n = 5) than to 5-ASA (n = 2).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Eight patients with inoperable hepatocellular carcinoma were treated by means of percutaneous alcoholization of the malignancy (11 nodular lesions less than 5 cm O). Upon treatment completion they were all given intraarterial injection of lipiodol, which was followed, a week later, by a CT scan. At angiography, during the parenchymal phase, 7 of 11 nodules appeared as avascular areas, whereas in the remaining 4 cases an intense parenchymal effect was seen within the previously treated areas. Lipiodol CT scans revealed intense uptake of oily material in the 4 hypervascular lesions as well as in 1 of those with avascular appearance. In 4 lesions, pathology of bioptic specimens obtained from the areas with contrast pooling was consistent with the persistence of viable neoplastic tissue. In these patients alcoholization had therefore to be continued. Lipiodol accumulation within previously treated nodules has proved to be related to the presence of residual neoplasm. Moreover, in 2 cases, focal retention of lipiodol was very helpful for biopsy under CT guidance. According to our experience, we believe lipiodol administration followed by CT to be very useful in evaluating and staging HCCs. We nevertheless believe that the procedure should be performed only after alcoholization has been completed: this would inform us of treatment effectiveness and subsequently enable us to decide whether treatment can be discontinued.

Abstract
The study aims to: (a) assess the incidence of functional/psychosomatic (FP) and psychiatric (P) calls to the Community Emergency Medical Service (during the night, week-ends, public holidays, when the primary care physicians are not on duty) and to determine the type of response provided; (b) highlight the diagnostic, relational, therapy and assistance problems involved in an approach to these patients at an emergency call level by a young, nonspecialist physician. The study data show that the quantitative importance of FP and P patients, as noted in the literature, is equally valid for emergency. But the study also highlights the numerous difficulties these patients cause to nonspecialist physicians. Liaison psychiatrist activity should find excellent growth potential in this new direction.

Abstract
Consultation-liaison psychiatry, which seeks to make a clinical and cultural contribution to medical problems, is the subject of considerable debate at a theoretical level. Moreover, at least in Italy, it is far removed from total actualization in practical terms. On the basis of a clinical experience, the authors underscore how a fully articulated and complete consultation and liaison program can facilitate a third form of collaboration provided by the psychiatrist, i.e. on-going training. The authors define this as the process of focusing in on the casework and psychotherapeutic competencies of the medical staff.

Abstract
The last 4 cases of our case series of renal cell carcinoma (RCC) with caval or cavo-atrial invasion were studied by ultrasonography (US), computerized tomography (CT scan), arteriography (AG) and venocavography (VC) (inferior and/or superior). A comparison is made with these different methods, with particular emphasis on (US). The authors' conclusions are that ultrasound may replace anterograde inferior cavography in the evaluation of thrombotic extension and, in addition, it seems to be capable of eliminating the false-positives or -negatives of this method. AG and VC are no longer necessary to determine the cavo-atrial extension of a tumor thrombus from RCC when US and CT scan are available and are correctly integrated.

Abstract
Women having recourse to repeated voluntary abortion are more and more numerous. Contraception is not a prophylactic mean for that, and it explains the interest to study the personality of women who abort repeatedly. We tested 41 of these women with the Minnesota Multiphasic. The answers showed psychotic and psychopathic tendencies, all the more as they were younger.
