Filter by:The purpose of this study is to evaluate the immunogenicity and safety of EV71 vaccine in infants aged 6 to 35 months old, by detecting the dynamic changes of neutralizing antibody at different time after vaccination
The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of EV71 vaccine with recombinant hepatitis B vaccine/Group A meningococcal polysaccharide vaccine.
The purpose of this study is to see if sucralfate, a medication commonly used for patients with stomach ulcers, may help pediatric patients with mouth ulcers decrease their pain level and improve their ability to drink.
Enterovirus 71 (EV71), a major pathogen causing hand-foot-and-mouth disease (HFMD) worldwide, is a member of the Human Enterovirus species A, family Picornaviridae. Its infection occasionally leads to severe diseases and death, with central nervous system (CNS) damage. An inactivated EV71 vaccine (Human Diploid cell, KMB-17 Cell) has been finished phase I, II and III clinical trials and licensed by CFDA in China at Dec. 3, 2015. Based on the results of clinical trials, the protective efficacy of inactivated EV71 vaccine is 97% against HFMD caused by EV71. The target population is determined to be susceptible children aged 6 to 71 months; this target population is well known as a major global population with strict requirements for safety and efficacy of vaccines in implementing the World Health Organization (WHO) Expanded Program on Immunization (EPI) . Thus, it is necessary and significant to conduct a postmarketing phase IV trial in large populations for long-term observation to evaluate the distinctive effectiveness and to identify potential safety issues . This study is an open-label and controlled postmarketing phase IV trial on children aged 6-71 months who resided in 3 districts of Xiangyang City, Hubei Province, China.
The purpose of the present investigation is to record and compare bacterial compositions in supragingival plaque samples and saliva samples in subjects discontinuing regular oral hygiene for 10 days. The hypothesis is that the composition of the salivary microbiota might reflect local bacterial alterations in relation to discontinuation of oral hygiene.
The purpose of the study was to assess the effectiveness of Faringomoss in reducing the throat discomfort and pain in patients with acute throat diseases and postoperative patients after throat surgeries.
Radiation therapy (RT) leads to a markedly reduced salivary secretion rate, which makes it difficult to eat and talk and it is a risk factor for oral disorders such as caries and mucosal infections. A reduced salivary secretion rate is often a life long side-effect of the treatment that seriously affect the quality of life. To reduce these side-effects the patients get preventive and supportive oral treatment in connection with their cancer treatment. However, regardless of radiation doses given, the severity of the problems vary considerably. Therefore, a better understanding on when and why problems occur is important for the identification of subjects at risk and to find better measures and treatments, suited for their individual needs. Dentate subjects were included referred before RT. Data were collected before and during treatment as well as 6, 12 and 24 months after completed RT. Cancer diagnosis, treatment, radiation doses, infections and medication were obtained from medical records. Dietary habits were registered using a questionnaire focusing on intake of carbohydrate-rich food-items and items containing sugar-substitutes. The subjects weight was registered before, during and after RT. A clinical examination was performed before and 6, 12 and 24 months after completed RT. Panoramic x-rays were taken as well as bitewing radiographs. The number of teeth, caries status, oral hygiene were registered. Mucositis was registered during RT. Secretion of stimulated whole saliva was determined. Minor labial and buccal gland saliva secretion rate was determined using the Periotron-method. Microbial samples were collected from the tongue, buccal mucosa and supragingival plaque and microorganisms associated with oral health and oral disorders analysed using cultivation technique. The quality of life was registered using the questionnaires EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire). To address additional symptoms associated specifically with cancer in the head and neck region and its treatment, a complementary 35-item module, the EORTC QLQ-H&N35 was used. The patients also completed the Hospital Anxiety and Depression Scales, HADS, which is used to measure severity of anxiety and depressive symptoms and provides estimates of possible mood disorders in patients with somatic comorbidity.
The gold standard for the treatment of gingival recession, is the coronal repositioning of the flap associated with the subepithelial connective tissue graft. The acellular dermal matrix (ADM) has been used as a substitute a subepithelial connective tissue graft in periodontal plastic surgery and mucogengivais, and has achieved similar results. The use of ADM has the advantage of avoiding possible pre and postoperative complications, as well as overcome the limitations presented by autograft. The different surgical techniques used for root coverage seek predictability and success. For this, besides the type of incision placements flap and graft are of utmost importance because the healing benefit and outcome. The aim of this study is to compare two surgical techniques for root coverage and evaluate which one provides better cosmetic results and less morbidity . 20 adults , nonsmoking patients , showing multiple bilateral gingival recessions , class I or II Miller located in canine, first and second premolars are selected. Both techniques use the ADM as a graft. However , in one Quadrant partial flap will be held together with relaxing incisions through an incision intrasucular , ADM will be positioned 1 mm apical to the cementoenamel junction (CEJ) and the flap will be positioned 1 mm coronal CEJ. In the opposite quadrant a minimally invasive technique periosteal envelope above does not use relaxing incisions , preserves the buds will be held , as well as avoiding any scars, the graft will be used to ADM. The clinical parameters (probing depth, clinical attachment level, bleeding on probing index, height and width of the gingival retraction and height and thickness of keratinized gingiva) will be evaluated 2 weeks after the basic periodontal therapy and after 6 and 12 months to surgical procedures. In addition, measurements of photographic gingival recession with the aid of software will be performed.
The purpose of the study is to evaluate if surgical treatment of peri-implantitis with enamel matrix derivative (Emdogain®, EMD) will have an additional effect on the healing outcome, changes in the peri-implant microflora and on the inflammatory response in the periimplant pocket at 12 months.
This study aims to investigate the prevalence of oral infection in chronic renal disease patients and to examine whether a focused oral hygiene intervention can reduce oral infection leading to reduced systemic inflammatory parameters in chronic renal disease patients in hemodialysis, chronic renal disease patients waiting for kidney transplantation, and chronic renal disease patients who has been transplanted 1-1½ year previously. The results will be compared to a gender- and age-matched healthy control group.
