1.Peroneal Neuropathy after Tibio-Fibular Fracture.
Annals of Rehabilitation Medicine 2011;35(5):648-657
OBJECTIVE: To investigate the injury mechanism in patients who had peroneal neuropathy after a tibio-fibular fracture and the correlation between tibio-fibular fracture location and the severity of the peroneal neuropathy by using electrodiagnosis. METHOD: Thirty-four patients with peroneal neuropathy after a tibio-fibular fracture were recruited for this study. Their medical records, radiologic and electrodiagnostic findings were investigated retrospectively. They were divided into 2 groups according to the existence of a fibular head fracture. The group of patients without the fibular head fracture was further classified according to the criteria of Orthopedic Trauma Association (OTA) classification. The differences between the two groups in the severity of the neuropathy and electrodiagnostic findings were evaluated. RESULTS: Nine cases (26.5%) had tibio-fibular fractures with a coexisting fibular-head fracture and 25 cases (73.5%) had tibio-fibular fractures without fractures in the fibular-head area. There was no statistical significance in the correlation between the existence of the fibular head fracture and the severity of the electrodiagnostic findings. Neither was there any statistically significant relationship between the site of the tibio-fibular fracture and the severity of the peroneal neuropathy (p>0.05). CONCLUSION: This study showed there were numerous cases with common peroneal neuropathy after tibiofibular fracture without a coexisting fibular-head fracture, which shows the importance of indirect nerve injury mechanisms as well as that of direct nerve injury as a cause of peroneal neuropathy. In addition, this study showed that there was no statistically significant correlation between the site of tibio-fibular fracture and the severity of peroneal neuropathy.

OBJECTIVE: In June 28, 2012, a 'Hospitalization guideline for car accident patients' was announced to mediate the clash of opinions about the hospitalization of minor head trauma patients among doctors, patients and insurance companies. The guideline was issued to describe the patients' symptoms and emotions in detail after the injury. In this paper, evaluation for the guideline and suggestions for modifications was done. METHODS: Thirty-two doctors, 96 patients and 60 employees were each given surveys about the hospitalization guidelines, related personnels' attitude and evaluation of patients' emotional problems. The frequency, ratio and chi-square test were performed. RESULTS: Sixty-eight point eight percent of doctors, 79.8% patients and 91.6% insurance company employees agreed to the need for a guideline. Among the 68.8% doctors that supported the need for a guideline, 18.8% knew that the guideline actually existed. Sixty-nine point two percent of doctors said that they would apply the guideline once they were introduced to it. Among the announced guideline provisions, 'Glasgow coma score less than 15' and 'socially not suitable for discharge' required reevaluation since 40.6% all surveyors consented that these two criteria were not suitable. The consensus supporting the need for emotional evaluation came out to be 78.1%, 58.5%, 50.9% in doctors, patients and insurance employees respectively. CONCLUSION: Although a guideline for hospitalization of minor head injury patients is necessary, some part of it seems to be reevaluated and improved, especially for clauses related to the patient's emotional problems. These changes and revisions to the guideline require further speculation and research.

Brugada syndrome is a rare channelopathy associated with the SCN5A gene that causes fatal ventricular arrhythmias. This case of Brugada syndrome, in which ventricular tachycardia (VT) was provoked by high fever, is the first report in a Korean child. The boy had retinoblastoma of his left eye diagnosed at 16 months of age. After chemotherapy, he contracted a catheter-related infection with a high fever up to 41degrees C leading to monomorphic VT. This was characterized as having right bundle branch block morphology, superior axis deviation, and a heart rate of 212/min. Direct current cardioversion recovered the VT to sinus rhythm after a lack of response to amiodarone and lidocaine. A second attack of VT that was not controlled by cardioversion, however, responded to lidocaine. The baseline electrocardiogram showed a long PR interval and QRS duration, and the patient's grandfather had a history of Brugada syndrome. A mutation in SCN5A was identified in this patient, his father, and his grandfather. The patient was treated with quinidine and followed up for 1 year.

Tuberculosis is primarily a pulmonary disease, but extra-pulmonary manifestations are not uncommon, especially in children and adolescents. Ten percent of extra pulmonary tuberculosis localizes to the bones and joints, and 56% of such cases affect the spine. We treated a childhood case of spinal tuberculosis misdiagnosed as muscular dystrophy in a patient without specific constitutional symptoms. We report this case because the patient had an unusual presentation of spinal tuberculosis.

Deep overbite patients who do not have proper occlusal relationship may cause problems such as teeth wear and antagonist extrusion. These lead to the collapse of occlusal plane and esthetic problem. Increasing vertical dimension is frequently essential to resolve those problems. This case report demonstrates a full-mouth rehabilitation for a patient with severe deep bite that contacts surface to surface by increasing vertical dimension. Treatment procedures included diagnosis, treatment planning, implant surgery, and prosthodontic rehabilitation. Satisfactory results were obtained in functional and esthetic aspects.

PURPOSE: Exaggerated pro-inflammatory reactions during the acute phase of Kawasaki disease (KD) suggest the role of immune dysregulation in the pathogenesis of KD. We investigated the profiles of T regulatory cells and their correlation with the clinical course of KD. METHODS: Peripheral blood mononuclear cells were collected from 17 KD patients during acute febrile and subacute afebrile phases. T cells expressing CD4, CD25, and Foxp3 were analyzed using flow cytometry, and the results were correlated with the clinical course of KD. RESULTS: The percentage of circulating CD4+CD25highFoxp3+ T cells among CD4+ T cells was significantly higher during the subacute afebrile phase than during the acute febrile phase (1.10%+/-1.22% vs. 0.55%+/-0.53%, P=0.049). Although levels of CD4+CD25lowFoxp3+ T cells and CD4+CD25-Foxp3+ T cells were only slightly altered, the percentage of CD4+CD25+Foxp3- T cells among CD4+ T cells was significantly lower during the subacute afebrile phase than during the acute febrile phase (2.96%+/-1.95% vs. 5.64%+/-5.69%, P=0.036). Consequently, the ratio of CD25highFoxp3+ T cells to CD25+Foxp3- T cells was higher during the subacute afebrile phase than during the acute febrile phase (0.45%+/-0.57% vs. 0.13%+/-0.13%, P=0.038). CONCLUSION: Decreased CD4+CD25highFoxp3+ T cells and/or an imbalanced ratio of CD4+CD25highFoxp3+ T cells to CD4+CD25+Foxp3- T cells might play a role in KD development. Considering that all KD patients were treated with intravenous immunoglobulin (IVIG), recovery of CD4+CD25highFoxp3+ T cells during the subacute afebrile phase could be a mechanism of IVIG.

BACKGROUND: Organizations are pursing complex and diverse aims to generate higher profits. Many workers experience high work intensity such as workload and work pressure in this organizational environment. Especially, psychological burden is a commonly used term in workplace of Republic of Korea. This study focused on defining the psychological burden from the perspective of occupational safety and health and tried to develop a scale for psychological burden. METHODS: The 48 preliminary questionnaire items for psychological burden were prepared by a focus group interview with 16 workers through the Copenhagen Psychosocial Questionnaire II and Mindful Awareness Attention Scale. The preliminary items were surveyed with 572 workers, and exploratory factor analysis, confirmatory factor analysis, and correlation analysis were conducted for a new scale. RESULTS: As a result of the exploratory factor analysis, five factors were extracted: organizational activity, human error, safety and health workload, work attitude, and negative self-management. These factors had significant correlations and reliability, and the stability of the model for validity was confirmed using confirmatory factor analysis. CONCLUSION: The developed scale for psychological burden can measure workers' psychological burden in relation to safety and health. Despite some limitations, this study has applicability in the workplace, given the relatively small-sized questionnaire.

The tongue, especially its lateral part, is the most common site of oral tumors. Patients who undergo glossectomy for the treatment of tongue cancer may experience difficulty in proper functioning for pronunciation, chewing, swallowing, and oral hygiene maintenance; therefore, a palatal augmentation prosthesis can be used to restore function of the tongue. In this case, an implant overdenture was used in a patient who had residual ridge resorption and obliteration of alveololingual sulcus after undergoing glossectomy for tongue cancer treatment. In addition, a palatal augmentation prosthesis with a metal framework, support, and retention part was fabricated. The palatal vault was reduced, so that even with limited tongue movement, adequate tongue-palate contact could be achieved. After placement of the definitive prostheses, the patient showed improvement in the functions of chewing, swallowing, and pronunciation.

Although low translucency 3 mol% yttria stabilized tetragonal zirconia polycrystal has excellent mechanical properties, it has limited application as a monolithic prosthesis. To improve these optical limitations, translucent zirconia has improved esthetics due to an increase in the cubic phase; however, it is accompanied by a decrease in mechanical properties simultaneously. Lithium disilicate has improved its mechanical properties through crystal size reduction and various heat treatment methods; therefore, its clinical application range is continuously increasing. Translucent zirconia shows a wide distribution of physical properties depending on the yttria content and lithium disilicate according to the size and density of crystal grains. As a result, the indications for translucent zirconia and lithium disilicate are increasing. Therefore, in this literature review, we intend to examine the rationale behind the material selection criteria in clinical situations and considerations for designing fixed dental prostheses including pontic, in particular, by summarizing recent studies.
