RESUMEN

OBJECTIVE: To compare the safety and efficacy of 10% sinecatechins (Veregen® ) ointment against placebo in the treatment of usual type vulvar intraepithelial neoplasia (uVIN). DESIGN: A Phase II double-blind randomised control trial. SETTING: A tertiary gynaecological oncology referral centre. POPULATION: All women diagnosed with primary and recurrent uVIN. METHODS: Eligible patients were randomised 1:1 to receive either sinecatechins or placebo ointment (applied three times daily for 16 weeks) and were followed up at 2, 4, 8, 16, 32 and 52 weeks. MAIN OUTCOME MEASURES: The primary outcome measure, recorded at 16 and 32 weeks, was histological response (HR). Secondary outcome measures included clinical (CR) response, toxicity, quality of life and pain scores. RESULTS: There was no observed difference in HR between the two arms. However, of the 26 patients who were randomised, all 13 patients who received sinecatechins showed either complete (n = 5) or partial (n = 8) CR, when best CR was evaluated. In placebo group, three patients had complete CR, two had partial CR, six had stable disease and two were lost to follow up. Patients in the sinecatechins group showed a statistically significant improvement in best observed CR as compared with the placebo group (P = 0.002). There was no difference in toxicity reported in either group. CONCLUSION: Although we did not observe a difference in HR between the two treatment arms, we found that 10% sinecatechins application is safe and shows promise in inducing clinical resolution of uVIN lesions and symptom improvement, thus warranting further investigation in a larger multicentre study. TWEETABLE ABSTRACT: A randomised control study indicating that sinecatechins ointment may be a novel treatment for uVIN.

RESUMEN

BACKGROUND: Puborectalis muscle rupture usually arises from peri-partum perineal trauma and may result in anterior, middle compartment prolapses, posterior compartment prolapse which includes rectocele and rectal prolapse, with or without associated anal sphincter damage. Patients with puborectalis muscle and levator ani rupture may present some form of incontinence or evacuation disorder, sexual dysfunction or pelvic organ descent. However, the literature on this subject is scarce. The aim of our study was to evaluate management and treatment of functional disorders associated with puborectalis and/or pubococcygei rupture at the level of the insertion in the pubis in a cohort of patients referred to a tertiary care coloproctology center. METHODS: We conducted a prospective cohort study of patients with levator ani and puborectalis muscle avulsion in the Proctology and Pelvic Floor Unit, Division of Digestive Surgery of the University Hospitals of Geneva from January 2001 to November 2018. Clinical examination, anoscopy and ultrasound were performed on a routine basis. Rupture of the levator ani muscle was diagnosed by clinical examination and ultrasound. A Wexner incontinence score was completed before and 6 months after surgery. Levator ani muscle repair was performed using a transvaginal approach. RESULTS: Fifty-two female patients (median age 56 ± 11.69 SD years, range 38-86 years) were included in the study. Thirty-one patients (59.6%) had anal incontinence, 25 (48.1%) urinary incontinence, 28 (53.9%) dyschezia (obstructive defecation or excessive straining to defecate), 20 (38.5%) dyspareunia, 17 (32.7%) colpophony, and 13 (25.0%) impaired sensation during sexual intercourse. Deviation of the anus on the side opposite the lesion was observed in 50 patients (96.2%), confirmed with clinical examination and both endoanal and perineal ultrasound. Out of these 52 patients, levator ani rupture (including puborectalis rupture) were categorized into right sided, 43 (82.69%), left sided, 7 (13.46%) and bilateral, 2 (3.85%). Levator ani muscle repair was performed in all patients, associated with posterior repair and levatorplasty in 26 patients (50%) and with sphincteroplasty in 34 patients (63.4%). Four patients (7.7%) experienced postoperative complications: significant postoperative pain (n = 3; 5.77%), urinary retention (n = 2; 3.85%), hematoma (n = 1; 1.92%), and perineal abscess (n = 1; 1.92%). Forty-one patients (78.8%) had full restoration of normal puborectalis muscle function (Wexner score: 0/20) after surgery, and overall, all patients had an improvement in the Wexner score and in sexual function. Dyschezia was reported by 28 patients (53.9%) preoperatively, resolved in 18 (64.3%) and improved by 50% or more in 10 (35.71%). CONCLUSIONS: Diagnosis of levator ani and puborectalis muscle rupture requires careful history taking, clinical examination, endoanal and perineal ultrasound. Surgical repair improved anal continence as well as sexual function in all patients. Transvaginal levator ani repair seems to be well tolerated with good short-term results.

RESUMEN

BACKGROUND: Automated classification of medical images through neural networks can reach high accuracy rates but lacks interpretability. OBJECTIVES: To compare the diagnostic accuracy obtained by using content-based image retrieval (CBIR) to retrieve visually similar dermatoscopic images with corresponding disease labels against predictions made by a neural network. METHODS: A neural network was trained to predict disease classes on dermatoscopic images from three retrospectively collected image datasets containing 888, 2750 and 16 691 images, respectively. Diagnosis predictions were made based on the most commonly occurring diagnosis in visually similar images, or based on the top-1 class prediction of the softmax output from the network. Outcome measures were area under the receiver operating characteristic curve (AUC) for predicting a malignant lesion, multiclass-accuracy and mean average precision (mAP), measured on unseen test images of the corresponding dataset. RESULTS: In all three datasets the skin cancer predictions from CBIR (evaluating the 16 most similar images) showed AUC values similar to softmax predictions (0·842, 0·806 and 0·852 vs. 0·830, 0·810 and 0·847, respectively; P > 0·99 for all). Similarly, the multiclass-accuracy of CBIR was comparable with softmax predictions. Compared with softmax predictions, networks trained for detecting only three classes performed better on a dataset with eight classes when using CBIR (mAP 0·184 vs. 0·368 and 0·198 vs. 0·403, respectively). CONCLUSIONS: Presenting visually similar images based on features from a neural network shows comparable accuracy with the softmax probability-based diagnoses of convolutional neural networks. CBIR may be more helpful than a softmax classifier in improving diagnostic accuracy of clinicians in a routine clinical setting.

RESUMEN

The global emergence of carbapenem-resistant Enterobacteriaceae (CRE) presents a significant clinical concern, prompting the WHO to prioritize CRE as a top priority pathogen in their 2017 global antibiotic-resistant bacteria priority list. Due to the fast-depleting antibiotic arsenal, clinicians are now resorting to using once-abandoned, highly toxic antibiotics such as the polymyxins and aminoglycosides, creating an urgent need for new antibiotics. Drug repurposing, the application of an approved drug for a new therapeutic indication, is deemed a plausible solution to this problem. A total of 1,163 FDA-approved drugs were screened for activity against a clinical carbapenem- and multidrug-resistant E. coli isolate using a single-point 10 µM assay. Hit compounds were then assessed for their suitability for repurposing. The lead candidate was then tested against a panel of clinical CREs, a bactericidal/static determination assay, a time-kill assay and a checkerboard assay to evaluate its suitability for use in combination with Tigecycline against CRE infections. Three drugs were identified. The lead candidate was determined to be Zidovudine (azidothymidine/AZT), an oral anti-viral drug used for HIV treatment. Zidovudine was shown to be the most promising candidate for use in combination with Tigecycline to treat systemic CRE infections. Further experiments should involve the use of animal infection models.

RESUMEN

Loop diuretics remain a fundamental pharmacological therapy to remove excess fluid and improve symptom control in acute decompensated heart failure. Several recent randomised controlled trials have examined the clinical benefit of continuous vs. bolus furosemide in acute decompensated heart failure, but have reported conflicting findings. The aim of this review was to compare the effects of continuous and bolus furosemide with regard to mortality, length of hospital stay and its efficacy profile in acute decompensated heart failure. All parallel-arm randomised controlled trials from MEDLINE, EMBASE, PubMed and the Cochrane Database of Systematic Reviews from inception until May 2017 were included. Cross-over randomised controlled trials, observational studies, case reports, case series and non-systematic reviews that involved children were excluded. Eight trials (n = 669) were eligible for inclusion. There was no difference between furosemide continuous infusion and bolus administration for all-cause mortality (four studies; n = 491; I2 = 0%; OR 1.65; 95%CI 0.93-2.91; p = 0.08) or duration of hospitalisation (six studies; n = 576; I2 = 71%; mean difference 0.27; 95%CI -1.35 to 1.89 days; p = 0.74). Continuous infusion of intravenous furosemide was associated with increased weight reduction (five studies; n = 516; I2 = 0%; mean difference 0.70; 95%CI 0.12-1.28 kg; p = 0.02); increased total urine output in 24 h (four studies; n = 390; I2 = 33%; mean difference 461.5; 95%CI 133.7-789.4 ml; p < 0.01); and reduced brain natriuretic peptide (two studies; n = 390; I2 = 0%; mean difference 399.5; 95%CI 152.7-646.3 ng.l-1 ; p < 0.01), compared with the bolus group. There was no difference in the incidence of raised creatinine and hypokalaemia between the two groups. In summary, there was no difference between continuous infusion and bolus of furosemide for all-cause mortality, length of hospital stay and electrolyte disturbance, but continuous infusion was superior to bolus administration with regard to diuretic effect and reduction in brain natriuretic peptide.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Elbasvir/grazoprevir is an all-oral regimen approved for patients with hepatitis C virus (HCV) genotypes 1 and 4, and in renal insufficiency. However, to date, no data exist on the efficacy of this regimen when it is crushed and administered through a percutaneous endoscopic gastrostomy (PEG) tube. Here, we illustrate the case of a 63-year-old man who is the only known patient with HCV infection in the English literature to have successfully achieved a sustained viral response (SVR) when elbasvir/grazoprevir oral combination was administered through a PEG tube. CASE SUMMARY: A 63-year-old man with worsening HCV-associated membranoproliferative glomerulonephritis was referred to the gastroenterology clinic for prompt HCV treatment. He had history of high-grade mucoepidermoid carcinoma of the parotid status post-resection and was expected to develop severe mucositis and dysphagia during radiation precluding typical oral therapy of his HCV. He received a PEG tube for nutrition and underwent a 16 week course of crushed Elbasvir/Grazoprevir for HCV treatment through the PEG. At the end of the therapy he achieved SVR and his kidney function also improved. WHAT IS NEW AND CONCLUSION: We present the first known clinical case of a non-cirrhotic patient with HCV genotype 1A with HCV-related MPGN treated successfully with crushed Elbasvir/Grazoprevir administered through a PEG tube. With the prevalence of PEG tube insertion and HCV on a rise, we expect these 2 population cohorts to intersect in the future. Our report may serve as a guidance in such clinical scenario.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Amiodarone, a commonly used class III antiarrhythmic agent notable for a relatively long half-life of up to 6 months and its pronounced adverse effect profile, is used for both acute and chronic management of cardiac arrhythmias. Chronic use of amiodarone has been associated with asymptomatic hepatotoxicity; however, acute toxicity is thought to be uncommon. There are only six reported cases of acute liver failure (ALF) secondary to amiodarone. In all these cases the outcome of death during the same hospitalization resulted. We aimed to report the only case of acute liver failure secondary to amiodarone infusion in the existing literature where the patient survived. CASE SUMMARY: A 79-year-old woman admitted with atrial flutter was being treated with intravenous (IV) amiodarone when she abruptly developed coagulopathy, altered mental status and liver enzyme derangement. She was diagnosed with acute liver failure (ALF) secondary to an amiodarone adverse drug reaction, with a calculated score of seven on the Naranjo adverse drug reaction probability scale. Amiodarone was immediately withheld, and N-acetylcysteine (NAC) was initiated. Clinical improvement was seen within 48 hours of holding the drug and within 24 hours of initiating NAC. On post-hospital follow-up visit she was reported to have complete recovery. WHAT IS NEW AND CONCLUSION: This report emphasizes the importance of monitoring liver enzymes and mental status while a patient is being administered IV amiodarone. N-acetylcysteine administration may have possibly contributed to the early and successful recovery from ALF in our patient. To date, she is the only patient in the existing literature who has been reported to survive ALF secondary to amiodarone administration.

RESUMEN

BACKGROUND: This investigator-initiated trial provided the justification for the phase III GRID study resulting in worldwide regulatory approval of regorafenib as a third-line therapy for patients with metastatic gastrointestinal stromal tumors (GIST). We report the genotype analyses, long-term safety, and activity results from this initial trial of regorafenib in GIST. PATIENTS AND METHODS: The trial was conducted between February 2010 and January 2014, among adult patients with metastatic GIST, after failure of at least imatinib and sunitinib. Patients received regorafenib orally, 160 mg once daily, days 1-21 of a 28-day cycle. Clinical benefit rate (CBR), defined as complete or partial response (PR), or stable disease lasting ≥16 weeks per RECIST 1.1, progression-free survival (PFS), overall survival (OS), long-term safety data, and metabolic response by functional imaging were assessed. RESULTS: Thirty-three patients received at least one dose of regorafenib. The median follow-up was 41 months. CBR was documented in 25 of 33 patients [76%; 95% confidence interval (CI) 58% to 89%], including six PRs. The median PFS was 13.2 months (95% CI 9.2-18.3 months) including four patients who remained progression-free at study closure, each achieving clinical benefit for more than 3 years (range 36.8-43.5 months). The median OS was 25 months (95% CI 13.2-39.1 months). Patients whose tumors harbored a KIT exon 11 mutation demonstrated the longest median PFS (13.4 months), whereas patients with KIT/PDGFRA wild-type, non-SDH-deficient tumors experienced a median 1.6 months PFS (P < 0.0001). Long-term safety profile is consistent with previous reports; hand-foot skin reaction and hypertension were the most common reasons for dose reduction. Notably, regorafenib induced objective responses and durable benefit in SDH-deficient GIST. CONCLUSIONS: Long-term follow-up of patients with metastatic GIST treated with regorafenib suggests particular benefit among patients with primary KIT exon 11 mutations and those with SDH-deficient GIST. Dose modifications are frequently required to manage treatment-related toxicities. CLINICAL TRIAL NUMBER: NCT01068769.

RESUMEN

OBJECTIVE: In this study, we investigated if the presence of histologically abnormal epithelium adjacent to the primary tumour influenced the frequency, timing, and topography of local vulvar recurrences (LVR) following treatment for squamous cell carcinoma of the vulva (VSCC). METHODS: The study population comprised a cohort of 201 consecutive cases with incident VSCC. LVR were categorised as local relapses (LR) if they occurred <2cm from the tumour margins, and as second field tumours (SFT) when ≥2cm from these margins. Univariable and multivariable competing risk modelling was performed to identify the prognostic factors associated with local disease recurrence. RESULTS: The characterization of the epithelium adjacent to the invasive component was possible for 199 (99.0%) patients. Of these, 171 (85.9%) were found to have intraepithelial abnormalities found adjacent to the surgical specimen. Multivariable analyses revealed that, following adjustment, Lichen Sclerosis (LS) was associated with an increase in the incidence of LVR, LR and SFT (SHRs: 3.4, 2.7 and 4.4, respectively). Although the incidence of LR and SFT in women with LS associated VSCC was similar, the peak incidence of SFT occurred more than two years before that of LR. CONCLUSIONS: Women with VSCC arising in a field of LS may continue to have an increased risk of developing LR and SFT for many years after resection of their primary tumour. Our study suggests that these women should be followed up more regularly so that LVR can be detected earlier; unless a more robust surveillance programme or chemopreventative treatments become available.

RESUMEN

BACKGROUND: As stapled hemorrhoidopexy (SH) becomes more widely used, we see more patients with chronic postoperative anal pain after this surgery. Its presentation is variable and difficult to treat. The aim of our study was to investigate the impact of chronic anal pain after SH and whether tailored therapy was likely to achieve a favorable outcome. METHODS: We retrospectively analyzed 31 consecutive patients with chronic anal pain who had undergone SH in other hospitals and were referred to our institutions. Depending on the type of pain, unrelated (at rest) or related to defecation, two groups of patients were identified. Moreover, the mean distance of the staple line from the anal verge was calculated in both groups. Treatments included: topical nifedipine, local anesthetic and steroid infiltration, removal of retained staples, anal dilation, and scar excision with mucosal suturing. A visual analog scale (VAS) was used to compare pain at baseline, postoperatively, and in the follow-up. This mean difference of the VAS score between stages was always used as the main outcome measure, depending on the type of presentation, type of pain, and type of treatment. Treatment response was defined as a 50 % decrease of VAS from baseline. RESULTS: There were 22 males and 9 females. The overall median age was 43 years (range 21-62 years). On digital examination and proctoscopy, 15 (48 %) patients had inflammatory changes, 19 (61 %) patients had staple retention, 8 (26 %) patients had anorectal stenosis, and 30 (97 %) patients had scar tissue. All patients had one or more of the following treatments listed from the least to most invasive: topical nifedipine in 12 (39 %) patients, anal dilation in 6 (19 %) patients, anesthetic and steroid infiltration in 18 (58 %) patients, removal of staples in 10 (32 %) patients, and scar excision in 18 (58 %) patients. The mean VAS score at baseline was 6.100, ± 1.953 SD, which dropped significantly after treatment to 1.733, ± 1.658 SD (p < 0.001) and remained low at follow-up (1.741 ± SD 1.251; p < 0.743). In patients with pain at rest (n = 20, 65 %), the symptoms improved in 19 (95 %) patients, while the VAS score decreased from 5.552 ± 2.115 SD to 1.457 ± 1.440 SD (95 % CI 3.217-4.964; p < 0.001). In patients with post-evacuation pain (n = 11, 35 %), the symptoms improved in 11 (100 %) patients, while the VAS score decreased from 6.429 ± 1.835 SD to 1.891 ± 1.792 SD (95 % CI 3.784-5.269; p < 0.001). Rating of response based on presentation was 90.0 % (0.9/10) after treatment of staple retention, which led to a significant decrease in the mean VAS score from 6.304 ± 1.845 SD to 1.782 ± 1.731 SD (95 % CI 3.859-5.185; p < 0.001). Anal stenosis was successfully treated in 100.0 % (n = 8/8) of cases with the mean VAS score dropping from 6.500 ± 1.309 SD to 2.125 ± 1.808 SD (95 % CI 2.831-5.919; p < 0.001). Anal inflammation improved in 60.0 % (n = 9/15) of patients and the mean VAS score dropped from 6.006 ± 2.138 SD to 1.542 ± 1.457 SD (95 % CI 3.217-4.964; p < 0.001). The response after scar tissue treatment was 94 % (n = 17/18) of patients with a mean VAS decreasing from 6.117 ± 2.006 SD to 1.712 ± 1.697 SD (95 % CI 3.812-4.974; p < 0.001). Success for topical nifedipine was between 13 and 25 % of patients depending on the clinical presentation. Anal dilation was successful in 75 % of patients, while Anesthetic and steroid infiltration in 23-54 % of patients depending on the clinical presentation. Staple removal was successful in 77 % of patients, and scar excision with mucosal suturing in 94 % of patients. CONCLUSIONS: Our retrospective study suggests that most patients with chronic anal pain after SH may be cured with treatment by applying a stepwise approach from the least to the most invasive treatment.

RESUMEN

Current listing indications used for intestinal transplantation (IT) were proposed in 2001. We undertook the present single center study to see if these criteria are still valid. The 2001 criteria (advanced cholestasis, loss of >50% central venous catheter (CVC) sites, ≥2 sepsis/year, ultrashort bowel) were compared in children with intestinal failure in old era-1998-2005 (N = 99) to current era-2006-2012 (N = 91) to predict the need for IT using sensitivity, specificity, NPV and PPV. Two 2001 criteria had poorer predictive value in the current era: Advanced cholestasis (PPV 64% old vs. 40% current era; sensitivity 84% vs. 65%, respectively) and ultrashort bowel (PPV 100% old vs. 9% current era; sensitivity 10% vs. 4%, respectively). Three newly proposed criteria had high predictive value: ≥2 ICU admissions (p = 0.0001, OR 23.6, 95% CI 2.7-209.8), persistent bilirubin >75 mmol/L despite lipid strategies (p = 0.0005, OR 24.0, 95% CI 3.2-177.4), and loss of ≥3 CVC sites (p = 0.0003, OR 33.3, 95% CI 18.8-54.0). There was 98% probability of needing IT when two of these new criteria were present. The 2001 IT criteria have limited predictive ability in the current era and should be revised. A multicenter study is required to validate the findings of this single center experience.

RESUMEN

BACKGROUND: Sacral nerve stimulation (SNS) has proven short- to medium-term effectiveness for the treatment of faecal incontinence (FI); fewer long-term outcomes have been presented and usually in small series. Here, the long-term effectiveness of SNS was evaluated in a large European cohort of patients with a minimum of 5 years' follow-up. METHODS: Prospectively registered data from patients with FI who had received SNS for at least 5 years from ten European centres were collated by survey. Daily stool diaries, and Cleveland Clinic and St Mark's incontinence scores were evaluated at baseline, after implantation and at the last follow-up. SNS was considered successful when at least 50 per cent symptom improvement was maintained at last follow-up. RESULTS: A total of 407 patients underwent temporary stimulation, of whom 272 (66·8 per cent) had an impulse generator implanted; 228 (56·0 per cent) were available for long-term follow-up at a median of 84 (i.q.r. 70-113) months. Significant reductions in the number of FI episodes per week (from median 7 to 0·25) and summative symptom scores (median Cleveland Clinic score from 16 to 7, St Mark's score from 19 to 6) were recorded after implantation (all P < 0·001) and maintained in long-term follow-up. In per-protocol analysis, long-term success was maintained in 71·3 per cent of patients and full continence was achieved in 50·0 per cent; respective values based on intention-to-treat analysis were 47·7 and 33·4 per cent. Predictive analyses determined no significant association between pretreatment variables and successful outcomes. Risk of long-term failure correlated with minor symptom score improvement during the temporary test phase. CONCLUSION: SNS remains an effective treatment for FI in the long term for approximately half of the patients starting therapy.

RESUMEN

Mimicry of two faces of an α-helix might yield more potent and more selective inhibitors of aberrant, helix-mediated protein-protein interactions (PPI). Herein, we demonstrate that a 2,6,9-tri-substituted purine is capable of disrupting the Mcl-1-Bak-BH3 PPI through effective mimicry of key residues on opposing faces of the Bak-BH3 α-helix.

RESUMEN

BACKGROUND: Vinegar is promoted as a natural appetite suppressant, based on previous reports that vinegar ingestion significantly increases subsequent satiety. However there are concerns about the appropriateness and safety of this advice, and it is unclear if poor product palatability may explain previously published effects on appetite. OBJECTIVE: To investigate if vinegar palatability and tolerability have a role in suppressing appetite and food intake in two sequential and related acute human feeding studies. SUBJECTS AND METHODS: Healthy, young, normal weight unrestrained eaters were recruited to Study 1 (n=16), an acute feeding study supplying vinegar within both palatable and unpalatable drinks alongside a mixed breakfast in comparison to a non-vinegar control; and to Study 2 (n=14), a modified sham feeding study (taste only without ingestion) comparing vinegar to a non-vinegar control following a milkshake preload. Both studies were a randomized crossover balanced design for the assessment of appetite, energy intake and glycaemic response. RESULTS: In Study 1, ingestion of vinegar significantly reduced quantitative and subjective measures of appetite, which were accompanied by significantly higher nausea ratings, with unpalatable treatment having the greatest effect. Significant correlations between palatability ratings and appetite measures were found. In Study 2, orosensory stimulation with vinegar did not influence subsequent subjective or quantitative measures of appetite compared with control. CONCLUSIONS: These studies indicate that vinegar ingestion enhances satiety whereas orosensory stimulation alone does not, and that these effects are largely due to poor tolerability following ingestion invoking feelings of nausea. On this basis the promotion of vinegar as a natural appetite suppressant does not seem appropriate.

RESUMEN

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) affects 30% of obese children globally. The main treatment for NAFLD is to promote gradual weight loss through lifestyle modification. Very little is known regarding parental perspectives about the barriers and facilitators that influence the ability to promote healthy lifestyle behaviours in children with NAFLD. OBJECTIVES: To explore and describe parental perspectives regarding barriers to and facilitators of implementing lifestyle modification in children with NAFLD. METHODS: A mixed-methods approach, including qualitative methodology (focus groups) and validated questionnaires (Lifestyle Behaviour Checklist), was used to assess parental perceptions regarding barriers to and facilitators of lifestyle change in parents of children with healthy body weights (control parents) and in parents of children with NAFLD (NAFLD parents). RESULTS: NAFLD parents identified more problem behaviours related to food portion size and time spent in nonsedentary physical activity, and lower parental self-efficacy than parents of controls (P<0.05). Major barriers to lifestyle change cited by NAFLD parents were lack of time, self-motivation and role modelling of healthy lifestyle behaviours. In contrast, control parents used a variety of strategies to elicit healthy lifestyle behaviours in their children including positive role modelling, and inclusion of the child in food preparation and meal purchasing decisions, and perceived few barriers to promoting healthy lifestyles. Internet sources were the main form of nutrition information used by parents. CONCLUSIONS: Lifestyle modification strategies focused on promoting increased parental self-efficacy and parental motivation to promote healthy lifestyle behaviour are important components in the treatment of obese children with NAFLD.


HISTORIQUE: Dans l'ensemble, 30 % des enfants obèses sont atteints d'une stéatose hépatique non alcoolique (SHNA). Le principal traitement de cette maladie consiste à promouvoir une perte graduelle de poids par des modifications au mode de vie. On ne sait pas grand-chose du point de vue des parents sur les obstacles et les incitations à promouvoir des comportements sains chez les enfants ayant une SHNA. OBJECTIFS: Explorer et décrire les points de vue des parents à l'égard des obstacles et des incitations à modifier le mode de vie pour les enfants ayant une SHNA. MÉTHODOLOGIE: Les chercheurs ont utilisé une démarche mixte, incluant une méthodologie qualitative (groupe de travail) et des questionnaires validés (liste de comportements et de modes de vie), pour évaluer les points de vue des parents à l'égard des obstacles et des incitations à modifier le mode de vie pour les parents d'enfants ayant un poids santé (parents témoins) et ceux d'enfants ayant une SHNA (parents SHNA). RÉSULTATS: Les parents SHNA percevaient plus de problèmes liés à la dimension des portions et au temps passé à des activités non sédentaires, et présentaient une autoefficacité parentale plus faible que les parents témoins (P<0,05). Comme obstacles majeurs aux modifications au mode de vie, les parents SHNA citaient le manque de temps, d'automotivation et d'exemple de comportements sains. Par contre, les parents témoins utilisaient diverses stratégies pour favoriser des comportements sains chez leurs enfants, y compris les exemples positifs, la participation des enfants à la préparation des repas et aux décisions relatives à l'achat des aliments, et percevaient peu d'obstacles à la promotion de modes de vie sains. Les parents utilisaient les sources virtuelles comme principales formes d'information en matière de nutrition. CONCLUSIONS: Les stratégies de modifications du mode de vie axées sur la promotion d'une meilleure autoefficacité parentale et sur la motivation des parents à promouvoir des comportements sains sont des éléments importants du traitement des enfants obèses ayant une SHNA.

RESUMEN

Renal impairment is frequently compromised in patients with end-stage liver disease and is associated with increased long-term mortality post-LT. In contrast to CNI, basiliximab is an immunosuppressive agent with minimal nephrotoxic potential. This study reviews the experience of a single pediatric liver transplant center's renal-sparing approach with the use of basiliximab and MMF to compensate for delayed entry of CNI in children with renal impairment at the time of organ availability. There were no differences in renal function between pediatric patients with and without pre-LT renal impairment within the first year (cGFR: 135 mL/min/1.73 m2 vs. 144 mL/min/1.73 m2 ; p = 0.56) or at 5-8 yr following LT, (129 mL/min/1.73 m2 vs. 130 mL/min/1.73 m2 ; p = 0.97). In addition, there was no difference in ACR rates (50% vs. 43%, p = 0.62) between patients in the basiliximab group and those patients receiving standard CNI and steroid strategies. The utilization of a renal-sparing approach with basiliximab alongside delayed entry and lower early target trough levels of CNI in children with renal impairment at the time of LT is safe and maintains excellent long-term kidney function.

RESUMEN

Between March 2007 and December 2009, 38 patients underwent sentinel lymph node biopsy (SLNB) sampling, along with vulvectomy, in their management of vulval cancer. A review has been conducted to establish the reliability and accuracy of the new procedure compared with the traditional total inguinofemoral lymphadenectomy. We also aimed to establish both the short- and long-term morbidities of both total inguinofemoral lymphadenectomy and SLNB and to assess the duration of hospital stay in both groups. Our data have shown a reduced short- and long-term morbidity and reduced length of hospital stay for the SLNB procedure. We conclude that it is a reliable and safe procedure, however it should only be conducted in cancer centres.
