  • Non-alcoholic fatty liver disease (NAFLD) is the most common cause of pediatric liver disease. Similar to NAFLD in adults, NAFLD in children is associated with obesity and insulin resistance and requires liver histology for diagnosis and staging. However, significant histological differences exist between adult and pediatric NAFLD. The rise in childhood obesity has been accompanied by an increase in pediatric NAFLD. Age, gender and race/ethnicity are significant determinants of risk, and sex hormones, insulin sensitivity and adipocytokines are implicated in the pathogenesis of pediatric NAFLD. There is no consensus for treatment of NAFLD, however, data suggest that diet, exercise and some pharmacological therapies may be of benefit. To evaluate and effectively treat pediatric NAFLD, the pathophysiology and natural history of the disease should be clarified and non-invasive methods for screening, diagnosis, and longitudinal assessment developed.

  • There has been a growing interest in sleep problems associated with attention deficit hyperactivity disorder (ADHD). In this paper, we reviewed the current literature on the underlying sleep problems associated with ADHD. Sleep problems are very common in children with ADHD. Patients with ADHD may have sleep difficulties including difficulty falling asleep, frequent night awakening, increased tiredness upon waking. Children with ADHD are associated to restless legs syndrome, periodic limb movement and sleep-disordered breathing. Screening for other psychiatric comorbidities and the side effects of medications, such as psychostimulants, is also necessary when considering sleep problems in ADHD. Sleep problems can cause a negative impact on the quality of life and emotional well-being both of children with ADHD and their parents. Many evidences suggest that assessment of sleep difficulties should be included in evaluating the patient of ADHD.

  • Background: Cervical cancer is one of the most common female malignancies with high mortality rates in developing countries. Our purpose was to determine the prevalence of cervical cytological abnormalities by cervical cytology (CC) and the analysis of risk factors in Albanian population. Materials and Methods: A total of 5,416 conventional pap smear tests collected between January 2009 and January 2012 from Tirana University Hospital Obstetrics-Gynecology "Queen Geraldine" were retrospectively analyzed. Results: A total of 258 (4.8%) cases had epithelial abnormalities. The numbers and rates were as follows: atypical squamous cell of undetermined significance (ASCUS; n=150 [2.76%]); atypical glandular cells of undetermined significance (AGUS; n=8 [0.14%]); low-grade squamous intraepithelial lesion (LSIL; n=87 [1.6%]); high- grade squamous intraepithelial lesion (HSIL; n=10 [0.18%]); and squamous cell carcinoma (SCC; n=3 [0.05%]). Conclusions: The prevalence of cervical cytological abnormality in our study was 4.8%. A larger community-based study may establish the exact prevalence of malignant and premalignant lesions, so as to plan for future screening.

  • In February 6-7th, the Thai National Cancer Institute, the International Agency for Research on Cancer and its Mumbai Hub for Cancer Registration, together with the International Association of Cancer Registries and the APOCP/APJCP, jointly organized an Asian cancer registry forum to discuss regional cooperation for cancer registration. Held in the Grande Mercure Fortune Hotel, Bangkok, the meeting brought together leading scientists in cancer registration from South-East and North-East Asia as well as Australia, India and Iran and IARC itself, with coverage of various priorities and challenges of cancer registries regarding cancer control policy, operational parameters, assessment of survival and contributions to screening, for example. The current situation was highlighted and future directions and possible expansion of activities were discussed, with especial attention to the necessity for networks to help improve cancer registration across Asia and Africa.

  • Xenograft models of human cancer play an important role in the screening and evaluation of candidates for new anticancer agents. The models, which are derived from human tumor cell lines and are classified according to the transplant site, such as ectopic xenograft and orthotopic xenograft, are still utilized to evaluate therapeutic efficacy and toxicity. The metastasis model is modified for the evaluation and prediction of cancer progression. Recently, animal models are made from patient-derived tumor tissue. The patient-derived tumor xenograft models with physiological characters similar to those of patients have been established for personalized medicine. In the discovery of anticancer drugs, standard animal models save time and money and provide evidence to support clinical trials. The current strategy for using xenograft models as an informative tool is introduced.

  • A stochastic simulation model incorporated with Reed-Frost approach was derived for evaluating diagnostic performance of a test used for a screening program of an infectious disease. The Reed-Frost model was used to characterize the within-herd spread of the disease using a hypothetical example. Specifically, simulation model was aimed to estimate the number infected animals in an infected herd, in which imperfect serologic tests are performed on samples taken from herds and to illustrate better interpreting survey results at herd-level when uncertainty inevitably exists. From a risk analysis point of view, model output could be appropriate in developing economic impact assessment models requiring probabilistic estimates of herd-level performance in susceptible populations. The authors emphasize the importance of knowing the herd-level diagnostic performance, especially in performing emergency surveys in which immediate control measures should be taken following the survey. In this context this model could be used in evaluating efficacy of a survey program and monitoring infection status in the area concerned.

  • There have been concerns about possible pathogenicity and antimicrobial resistance in Enterococcus, which constitute more than 50% of probiotics in the worldwide market. In this study, Enterococcus in sixteen products manufactured by ten different companies was tested for the presence of six virulence genes and two vancomycin resistance genes. Results in this study showed the safety of Enterococcus on the Korean market and the importance of screening vanA, vanE, agg, cylA, esp, and gelE. Pulse-field gel electrophoresis showed that the sixteen isolates tested in this study are originated from three strains.

  • The risk assessment of thermal behavior and runaway reaction cased by an exothermic batch process in manufacture of the vinyl acetate resin are described in the present paper. The aim of the study was to evaluate the risk of runaway reaction with operating parameters such as a reaction inhibitor, reaction temperature and a mount of methanol charged in the vinyl acetate polymerization process. The experiments were performed by a sort of calorimetry with the Multimax reactor system as a screening tool to investigate runaway reaction. From the experimental results, it was found that we could occur the auto acceleration for reaction of raw materials with operating parameters over $65^{\circ}C$ of reaction temperature in the vinyl acetate polymerization process.
