  • Implant prosthodontics is beneficial for edentulous patients in enhancing the support, retention, stability, phonation and so on. Various types of prosthesis supported by implant, including implant retained- or supported- overdenture for the removable type and ceramo-metal and fixed prostheses with processed acrylic teeth for the fixed type, are frequently used. Treatment planning for the prosthesis with implant must be made after considering individual characteristics such as form of residual ridge, soft tissue, interocclusal relationship, economic status. Fixed prosthesis with processed acrylic teeth (also known as 'implant hybrid prosthesis' or 'bone anchored bridge') has the advantages of both removable and fixed prosthesis such as proper soft tissue profile, esthetic outcome, increased masticatory efficiency and psychological stability. The 73-years-old female patient came to the department of prosthodontics, Dental hospital of Yonsei University. She was diagnosed with Kennedy class I partial edentulism in the maxilla and complete edentulism in the mandible. This article reports a satisfactory clinical and esthetic outcome of full mouth rehabilitation using removable partial denture in the maxilla and implant hybrid prosthesis in the mandible.

  • Buckley's formocresol was first introduced as a pulp medicament in 1904, and since 1930, it has been the treatment of choice for primary molar pulpotomies. Formocresol has fixation effect of pulp tissue and high clinical success rate. But side effect such as displacement and loss of permanent successor, amelogenesis imperfecta, cyst formation, mutation by general absorption, possibility of cancer induction have been reported. Of those, dentigerous cyst can form in the periradicular region after formocresol pulpotomy caused by an alteration of the reduced enamel epithelium, which result in fluid accumulation between the epithelium and the tooth crown. The present case describes a 6-year-old girl who had accidentally discovered in the panoramic radiograph a single, well-defined, radioluscent area enclosing the second unerupted mandibular premolar. The second left primary molar had been pulpotomizied 3 year before. Surgical treatment was carried out, the primary molar was extracted and cystectomy was performed under local anesthesia. In the extracted second primary molar, formocresol cotton pellet was left in the pulp chamber. Histologic study confirmed the suspected diagnosis of dentigerous cyst. This report present a case of dentigerous cyst associated with inadequate formocresol pulpotomized deciduous molar.

  • The discovery and understanding of antigenic proteins are essential for development of a vaccine against malaria. In Plasmodium falciparum, Pf92 have been characterized as a merozoite surface protein, and this protein is expressed at the late schizont stage, but no study of Pv92, the orthologue of Pf92 in P. vivax, has been reported. Thus, the protein structure of Pv92 was analyzed, and the gene sequence was aligned with that of other Plasmodium spp. using bioinformatics tools. The recombinant Pv92 protein was expressed and purified using bacterial expression system and used for immunization of mice to gain the polyclonal antibody and for evaluation of antigenicity by protein array. Also, the antibody against Pv92 was used for subcellular analysis by immunofluorescence assay. The Pv92 protein has a signal peptide and a sexual stage s48/45 domain, and the cysteine residues at the N-terminal of Pv92 were completely conserved. The N-terminal of Pv92 was successfully expressed as soluble form using a bacterial expression system. The antibody raised against Pv92 recognized the parasites and completely merged with PvMSP1-19, indicating that Pv92 was localized on the merozoite surface. Evaluation of the human humoral immune response to Pv92 indicated moderate antigenicity, with 65% sensitivity and 95% specificity by protein array. Taken together, the merozoite surface localization and antigenicity of Pv92 implicate that it might be involved in attachment and invasion of a merozoite to a new host cell or immune evasion during invasion process.

  • Background and Objectives : The effect of palliative injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients on voice and swallowing function is uncertain and there are few previous studies of its suitability, benefits as a palliative treatment option. The purpose of this study is to confirm the objective results of voice and swallowing function after palliative office-based hyaluronic acid injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients. Materials and Method : 36 patients who had unilateral vocal cord paralysis from non-thyroidal, extralaryngeal neoplasms were included in this study. To evaluate the clinical outcome, we analyzed perceptual GRBAS grading, acoustic analysis, aerodynamic study, Electroglottography (EGG), Voice Handicap Index (VHI-30) about voice function and disability rating scale (DRS), gastric tube dependency, aspiration pneumonia about swallowing function and 36-Item Short Form Survey version 2 (SF-36v2) about quality of life. Results : In GRBAS scale, G (p<0.001), R (p=0.004), B (p=0.001), A (p=0.011), and S (p=0.007) showed significant improvement. Jitter, shimmer, speaking fundamental frequency, maximal phonation time, VHI-30, DRS score, gastric tube dependency, aspiration pneumonia, and SF-36v2 were significantly improved after injection (p=0.016, p=0.011, p=0.045, p=0.005, p<0.001, p<0.001 p=0.003, p<0.001, and p<0.001 respectively). Conclusion : From this study we concluded office-based hyaluronic acid injection can be used as a useful palliative treatment option in cancer-related ill patients with unilateral vocal cord paralysis. Palliative hyaluronic acid injection laryngoplasty avoids the need for tube feeding, thus reducing the risk of aspiration pneumonia. These outcomes are accompanied by significant improvement in voice quality.

  • Background: Colposcopy is the gold standard procedure for evaluating cervical cytological abnormalities. Although it is essentially a minimally invasive intervention, referral for colposcopy may cause significant distress on patients. In this study, we aimed to determine if pre-procedural anxiety levels have a significant association with procedure related pain and discomfort in women undergoing colposcopy for evaluation of abnormal cervical cytology. We also assessed the impact of various clinical factors on anxiety, pain and discomfort in these patients. Materials and Methods: This prospective study was performed at the gynecologic oncology department of Zekai Tahir Burak Women's Health Education and Research Hospital in Ankara, Turkey between January and June 2013. After taking informed consent, State-Trait Anxiety Inventory (STAI) form and a 14-item questionnaire were filled for women who were admitted to our outpatient colposcopy unit for evaluation of abnormal cervical cytology. STAI scores were calculated for each participant. Immediately after the procedure, visual analog scale (VAS) scores for procedure-related pain and discomfort were obtained. Associations between STAI and VAS scores were investigated using correlation analyses. The effect of various contributing factors on anxiety, pain and discomfort were evaluated with linear regression analysis. The p values less than 0.05 were considered statistically significant. Results: A total of 222 women met the inclusion criteria within the study period. Mean patient age was $38.5{\pm}9.6$. Median state and trait anxiety scores were 47 and 46, respectively. Median VAS scores for pain and discomfort were 4 for both variables. State anxiety had a significant correlation with procedure related discomfort (p=0.02). Colposcopy related pain VAS scores were significantly affected by state anxiety level, marital status and prior gynecological examination (p<0.05). Colposcopy related discomfort VAS scores were significantly affected by state anxiety level, marital status, prior gynecological examination and educational status. Conclusions: Additional measures should be implemented in women that carry higher risk for experiencing pain and discomfort. Social, cultural and lifestyle issues may also affect women's experiences during colposcopy, therefore further studies are needed to define specific determining factors in various populations.

  • Lymphocytic interstitial pneumonitis (LIP) is one of parenchymal pulmonary infiltrative diseases first described at 1966 by Carrington and Liebow. In LIP, there is a predominance of mature small lymphocytes in the interstitium of the lung which form germinal centers. The disease process surrounds, but dose not invade lung parenchyme, tracheobronchial tree and vascular structures. The etiology remains still unknown and the clinical features of this disorder have not been clearly defined. Therefore, the therapeutic modality is obscure. Development of LIP association with AIDS is often reported currently and possibility of progress to malignant lymphoma is emphasized. We experienced a case of primary LIP with pnemomediastinum. She was adimitted due to chest and anterior nuchal pain with chronic coughing, and diagnosed as pneumomediastinum with LIP. Medication with steroid was begun and some improvement of symptoms was observed, but an X-ray film of the chest remained same without improvement. We report above case with review of the literatures.

  • Occlusal plane is a sagittal expression of dental arch form, and it composes the shape of occlusion, which is one of the most important elements of Maxillo-oral system. In this case, vertical, horizontal coordinates of bionic-median-sagittal plane was produced in articulator, and to achieve relation of left and right position of upper, lower teeth and deficits in alveola, Shilla system was used to reconstruct occlusal plane. In this case, a 41 year-old male patient visited for fracture of 10 unit metal-ceramic fixed partial denture of upper anterior teeth and for overall treatment. Clinical, radiographical, model examination was held, full mouth rehabilitation was achieved by placing dental implant. Maxillo-oral relation was recorded using Gothic arch Tracer complex and were mounted. And for the next step, we estimated original occlusal plane using Shilla system. After analysis we produced diagnosis wax pattern. On the basis of this, radiography stent was manufactured and dental implant was placed, and temporary prosthesis was made by using diagnosis wax pattern. Cross mounting and anterior guiding table were performed in order to reproduce temporary restoration morphology and bite pattern, followed by final restoration made of all ceramic crown with zirconia coping. As stated above, appropriately esthetic and functional results can be seen in using Shilla system in diagnosis and treatment procedure of full mouth rehabilitation patient.

  • Objective : In this study, we investigated the prevalence of depression and its impact on the healthrelated Quality of life (HRQoL) of the patients with End-Stage Renal Disease (ESRD) on Hemodialysis. Method : The Quality of life (QOL) of patients was evaluated by HRQoL Questionnaire, "Medical Outcome Survey 36-Item Short Form Health Survey Korean Version (SF-36-K)". The patients on Hemodialysis in ESRD, were chosen from the hemodialytic room at Wonkwang University and Jeongeup-Asan Hospital. The number of patients was 95 (64 from Wonkwang University Hospital and 31 from Jeongeup-Asan Hospital) and all of them were above 19 years old. We performed various investigations to find a statistical correlations between HRQoL and physical & psychosocial factors such as the demographic characteristics, clinical characteristics (hemoglobin level and albumin level etc), and the score of Beck's depressive inventory (BDI). Results : The HRQoL value of patients on hemodialysis in ESRD is far poorer than the HRQoL reference value of Koreans and Americans, who are in normal healthly. The prevalence of depressive symptoms by BDI of the ESRD patients on hemodialysis is 68.6%, and age and depression have negative correlations with HRQoL of the patients. However, education level, serum albumin level, and social support have positive correlations with HRQoL. The patient group with depression has significantly poorer HRQoL than the group without depression. Conclusion : The HRQoL of ESRD patients on hemodialysis is not good in both physical and mental aspects. The prevalence of depression is very high and depression has negative impact of HRQoL of patients. Based on our study, it is essential to accompany with therapeutic Strategy to improve the HRQoL of ESRD patients on hemodialysis.
