Handwriting is the result of a process in which linguistic, psychomotor and biomechanical factors interact with physical maturation, cognitive development and learning. Digital tablets, which record the writing in real time, allow a kinematic analysis of written trace: the implemented algorithms analyze parameters as length, duration and speed of the components (trace between two pen-lifts) and strokes (trace between two minima of curvilinear velocity). The purpose of this work is to fill, at least for Italy, the lack of normative data on typical handwriting processes. This cross-sectional study will present data on 218 right-handed and Italian mother-tongue students, attending classes from 2nd to 8th grade. They performed specific tasks (tests of writing speed; transcription of a sentence accurately vs. speedily) by a digital tablet. The analysis showed many changes of the considered parameters across the classes, as in the horizontal, curvilinear mean and peak velocities of components and strokes, with higher values in the last years of schooling and a parallel decrease in the number of strokes/letter (improvement of automation). In conclusion, some of these parameters are useful for studying development and learning of writing and their values can be used as references to evaluate samples with different characteristics. © 2012 Elsevier B.V.

Objective We report the technique to performminilaparoscopic nerve sparing radical hysterectomy (NSRH) in locally advanced cervical cancer. Methods Three patients aged 32, 53, and 51 respectively (median 46), with a median body mass index of 23 (18-26), one nulliparous and two pluriparous, were diagnosed with cervical squamous carcinoma on cervical biopsy, FIGO stage II B, and underwent a minilaparoscopic NSRH, bilateral salpingo-oophorectomy and systematic pelvic lymphadenectomy after neoadjuvant radiochemotherapy (pelvic irradiation in 22 fractions 1.8 Gy/day, totaling 39.6 Gy in combination with cisplatin 20 mg/m 2, 2-h intravenous infusion and 5-fluorouracil 1000 mg/m 2, 24-h continuous intravenous infusion, both on days 1-4 and 27-30) according to a protocol in our Institution [1,2]. Operative technique The procedures required a 5 mm 0 endoscope (Endoeye, Olympus Winter& Ibe GmbH, Hamburg-Germany) inserted in a trans-umbilical optical viewing port (Endopath Xcel, Ethicon Endo-surgery, Cincinnati, OH) and three additional sovrapubic 3-mm diameter ports placed. Three millimeter instruments were employed including atraumatic graspers, monopolar scissors, a suction-washing system (Karl Storz Endoskope-3 mm Instrument set, Tuttlingen Germany) and bipolar coagulator (Robi, Karl Storz). As already described, after pelvic and abdominal exploration, the operation starts with the coagulation and transection of the round ligament next to the pelvic wall and the opening of the anterior and posterior peritoneal layers of the broad ligament in order to enter the pelvic retroperitoneum. Once developed the paravesical and pararectal spaces the ureter can be easily identified. The uterine artery is then isolated and coagulated at its origin from umbilical artery. Before starting the pelvic lymphadenectomy, the dissection of the paravesical space laterally to the obliterated umbilical artery needs to be completed until the obturator nerve is identified. External and common iliac lymph nodes are removed from vessel surfaces by blunt or sharp dissection. Moreover, the obturator fossa is entered laterally and the obturator nerve and vessels are skeletonized before removing superficial and deep obturator lymph nodes. The anatomical margins for the pelvic lymph node dissection are medially the ureter, laterally the psoas muscle and the genitofemoral nerve, posteriorly the obturator nerve and cranially the mid portion of the common iliac artery. The same procedure was performed on the controlateral side. Once the ureter is identified, the infundibulopelvic ligament can be coagulated and transected. The pararectal space is then developed in a medial portion (Okabayashi space) and in a lateral portion (Latzko space), having the ureter in the middle. This maneuver allows the surgeon to identify the inferior hypogastric nerve, that appears approximately 2-3 cm dorsally of the ureter in the lateral part of the uterosacral ligament when entering the lateral parametrium. After its identification, this nerve is followed until it runs dorsally to the deep uterine vein. At this point the pelvic splanchnic nerves running from the S2-S4 roots of the sacral plexus join in the inferior hypogastric plexus with the inferior hypogastric nerves. After the identification of the above mentioned nerve structures, we performed a radical resection of the uterosacral and paracervical tissues according to the nerve sparing technique [3,4]. The paracervical tissue and the uterosacral ligaments were transected combining monopolar and bipolar devices with the vessel by vessel technique. Dissection of the ureteral tunnel and vesicovaginal spaces was accomplished with monopolar and blunt technique and with the aid of bipolar coagulation. At that point, the vaginal wall was identified and transected with a monopolar hook using pure section energy to avoid postoperative ureteral and bladder complications. The specimens were removed vaginally. The vaginal cuff was then closed transvaginally. A hydropneumatic test for bladder integrity was performed at the end of the procedure. The laparoscopic access points were only closed by steri-strips. Results All surgical procedures were completed as planned. Median operative time was 192 min (173-217) and the estimated blood loss was less than 50 mL in all cases. No post-operative complications occurred. Post-void residual was less than 100 mL in post-operative day 2. All patients were discharged on postoperative day 3. The pathology report revealed a median residual tumor of 8 mm (6-12) in all cervical specimens. The median width of parametrical tissue and length of vaginal cuff were 23 mm (20-27) and 18 mm (15-24), respectively. A median of 26 (21-33) lymph nodes had been harvested and were negative for metastasis. None of these three patients required adjuvant treatment. Over a median follow-up of 10 months all patients had no evidence of disease. Conclusions This surgical video testifies the technical feasibility ofminilaparoscopy NSRH producing surgico-pathologic data in line with what has recently been published [5,6].

Recent Patents on Anti-Cancer Drug Discovery | Year: 2012
Multicellular organisms require apoptosis whereby the human body eliminates unnecessary and/or damaged cells. Apoptosis, or programmed cell death, can indeed be considered as a constitutive anti-cancer mechanism that seems to be defective in more than 50% of cancers. Molecular insights on the biology of the apoptotic process have led to the development of new anti-cancer strategies aiming at recovering and stimulating this process. Preclinical and clinical studies of our and other groups have demonstrated that targeting the extrinsic apoptotic pathway by various death receptors agonists is a safe and effective anti-cancer strategy, which thus may become a new cornerstone of cancer therapy. Here, we review the most recent acquisitions and patents on TRAIL or TRAIL mimetics, as well as the combination therapies that could be used with them. © 2012 Bentham Science Publishers.

Food allergy is a serious health issue aff ecting roughly 4% of children, with a substantial eff ect on quality of life. Prognosis is good for the most frequent allergens with almost all children outgrowing their allergy. However, the long-term implications for disease burden are substantial for children with persistent allergies (eg, peanuts, tree nuts, fi sh, and shellfi sh) and for those with high concentrations of milk, egg, and wheat IgE. Antigen avoidance has been the time-honoured approach both for prevention and treatment. However, fi ndings from studies done in the past 5 years show that early contact with food can induce tolerance and desensitisation to foods. We review the epidemiology, natural history, and management of food allergy, and discuss the areas of controversy and future directions in research and clinical practice.

BACKGROUND: Widespread recommendations from health organisations encourage exclusive breastfeeding for six months. However, the addition of other fluids or foods before six months is common in many countries and communities. This practice suggests perceived benefits of early supplementation or lack of awareness of the possible risks.OBJECTIVES: To assess the benefits and harms of supplementation for full-term healthy breastfed infants and to examine the timing and type of supplementation.SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 March 2014) and reference lists of all relevant retrieved papers.SELECTION CRITERIA: Randomised or quasi-randomised controlled trials in infants under six months of age comparing exclusive breastfeeding versus breastfeeding with any additional food or fluids.DATA COLLECTION AND ANALYSIS: Two review authors independently selected the trials, extracted data and assessed risk of bias.MAIN RESULTS: We included eight trials (984 randomised infants/mothers). Six trials (n = 613 analysed) provided data on outcomes of interest to this review. The variation in outcome measures and time points made it difficult to pool results from trials. Data could only be combined in a meta-analysis for one secondary outcome (weight change). The trials that provided outcome data compared exclusively breastfed infants with breastfed infants who were allowed additional nutrients in the form of artificial milk, glucose, water or solid foods.In relation to the majority of the older trials, the description of study methods was inadequate to assess the risk of bias. The two more recent trials, were found to be at low risk of bias for selection and detection bias. The overall quality of the evidence for the main comparison was low.In one trial (170 infants) comparing exclusively breastfeeding infants with infants who were allowed additional glucose water, there was a significant difference favouring exclusive breastfeeding up to and including week 20 (risk ratio (RR) 1.45, 95% confidence interval (CI) 1.05 to 1.99), with more infants in the exclusive breastfed group still exclusively breastfeeding. Conversely in one small trial (39 infants) comparing exclusive breastfed infants with non-exclusive breastfed infants who were provided with artificial milk, fewer infants in the exclusive breastfed group were exclusively breastfeeding at one week (RR 0.58, 95% CI 0.37 to 0.92) and at three months (RR 0.44, 95% CI 0.26 to 0.76) and there was no significant difference in the proportion of infants continuing any breastfeeding at three months between groups (RR 0.76, 95% CI 0.56 to 1.03).For infant morbidity (six trials), one newborn trial (170 infants) found a statistically, but not clinically, significant difference in temperature at 72 hours (mean difference (MD) 0.10 degrees, 95% CI 0.01 to 0.19), and that serum glucose levels were higher in glucose supplemented infants in the first 24 hours, though not at 48 hours (MD -0.24 mmol/L, 95% CI -0.51 to 0.03). Weight loss was also higher (grams) in infants at six, 12, 24 and 48 hours of life in the exclusively breastfed infants compared to those who received additional glucose water (MD 7.00 g, 95% CI 0.76 to 13.24; MD 11.50 g, 95% CI 1.71 to 21.29; MD 13.40 g, 95% CI 0.43 to 26.37; MD 32.50 g, 95% CI 12.91 to 52.09), but no difference between groups was observed at 72 hours of life. In another trial (47 infants analysed), we found no significant difference in weight loss between the exclusively breastfeeding group and the group allowed either water or glucose water on either day three or day five (MD 1.03%, 95% CI -0.18 to 2.24) and (MD 0.20%, 95% CI -1.18 to 1.58).Three trials with four- to six-month-old infants provided no evidence to support any benefit from the addition of complementary foods at four months versus exclusive breastfeeding to six months nor any risks related either morbidity or weight change (or both).None of the trials reported on the remaining primary outcomes, infant mortality or physiological jaundice.AUTHORS' CONCLUSIONS: We were unable to fully assess the benefits or harms of supplementation or to determine the impact from timing and type of supplementation. We found no evidence of benefit to newborn infants and possible negative effects on the duration of breastfeeding from the brief use of additional water or glucose water, and the quality of the evidence from a small pilot study on formula supplementation was insufficient to suggest a change in practice away from exclusive breastfeeding. For infants at four to six months, we found no evidence of benefit from additional foods nor any risks related to morbidity or weight change. Future studies should examine the longer-term effects on infants and mothers, though randomising infants to receive supplements without medical need may be problematic.We found no evidence for disagreement with the recommendation of international health associations that exclusive breastfeeding should be recommended for healthy infants for the first six months.

Purpose: To investigate the potential link between C-reactive protein (CRP), a known biomarker of acute and chronic inflammation, and TRAIL, a cytokine which plays a key role in the immune-surveillance against tumors. Experimental Design: Primary normal peripheral blood mononuclear cell (PBMC) and CD14+ monocytes were exposed to recombinant CRP (1-10 μmol/L). TRAIL expression was analyzed by ELISA and/or by quantitative real-time PCR (qRT-PCR). In parallel, the potential role of the transcription factor Egr-1 was investigated by analyzing its modulation in response to CRP and by transfection experiments. Results: In vitro CRP exposure induced downregulation of TRAIL expression, both at the mRNA and protein level, in unfractionated PBMC and in purified CD14+ monocytes. TRAIL downregulation was not due to a specific toxicity or to contaminating lipopolysaccharide (LPS), as shown by the lack of induction of monocyte apoptosis and by the inability of the inhibitor of LPS polymyxin B to interfere with CRP activity. Of note, CRP downregulated TRAIL expression/release in CD14+monocytes also in response to IFN-α, the most potent inducer of TRAIL. At the molecular level, the downmodulation of TRAIL by CRP was accompanied by a significant increase of Egr-1. Consistently, Egr-1 overexpression reduced the baseline levels of TRAIL mRNA, whereas knocking down Egr-1 counteracted the ability of CRP to downregulate TRAIL. Conclusions: Our findings suggest that a chronic elevation of CRP, which occurs during systemic inflammation and often in patients with cancer, might contribute to promote cancer development and/or progression by downregulating TRAIL in immune cells. ©2013 AACR.

Objective To systemically review the evidence in support of World Health Organization guidelines recommending broad-spectrum antibiotics for children with severe acute malnutrition (SAM).Methods CENTRAL, MEDLINE, EMBASE, LILACS, POPLINE, CAB Abstracts and ongoing trials registers were searched. Experts were contacted. Conference proceedings and reference lists were manually searched. All study types, except single case reports, were included. Findings Two randomized controlled trials (RCTs), one before-and-after study and two retrospective reports on clinical efficacy and safety were retrieved, together with 18 pharmacokinetic studies. Trial quality was generally poor and results could not be pooled due to heterogeneity. Oral amoxicillin for 5 days was as effective as intramuscular ceftriaxone for 2 days (1 RCT). For uncomplicated SAM, amoxicillin showed no benefit over placebo (1 retrospective study). The introduction of a standardized regimen using ampicillin and gentamicin significantly reduced mortality in hospitalized children (odds ratio, OR: 4.0; 95% confidence interval, CI: 1.7-9.8; 1 before-and-after study). Oral chloramphenicol was as effective as trimethoprim-sulfamethoxazole in children with pneumonia (1 RCT). Pharmacokinetic data suggest that normal doses of penicillins, cotrimoxazole and gentamicin are safe in malnourished children, while the dose or frequency of chloramphenicol requires adjustment. Existing evidence is not strong enough to further clarify recommendations for antibiotic treatment in children with SAM. Conclusion Large RCTs are needed to define optimal antibiotic treatment in children with SAM with and without complications. Further research into gentamicin and chloramphenicol toxicity and into the pharmacokinetics of ceftriaxone and ciprofoxacin is also required.

Paracetamol (acetaminophen) is one of the most popular and widely used drugs for the treatment of pain and fever in children. This drug has multiple mechanisms of action, but its pharmacodynamic is still not well known. The central nervous system is the main site of action and it mirrors the paracetamol effect compartment. The recommended dosages and routes of administration should be different whether paracetamol is used for the treatment of pain or fever. For example, the rectal route, while being efficacious for the treatment of fever, should be avoided in pain management. Paracetamol is a safe drug, but some clinical conditions and concomitant drugs, which are frequent in clinical practice, may increase the risk of paracetamol toxicity. Therefore, it is important to optimize its administration to avoid overdoses and maximize its effect. The principal mediator of the paracetamol toxicity is the N-acetyl-p-benzo-quinone imine (NAPQI), a toxic product of the paracetamol metabolism, which could bind cysteine groups on proteins forming paracetamol-protein adduct in the liver. Conclusion: Although frequently prescribed, the concept of "effect compartment concentration" and the possible co-factors that could cause toxicity at recommended doses are not familiar to all pediatricians and general practitioners. We reviewed the literature concerning paracetamol mechanisms of action, we highlighted some relevant pharmacodynamic concepts for clinical practice, and we summarized the possible risk factors for toxicity at therapeutic dosages. © 2013 Springer-Verlag.
