Following Bright and Gray Matter Degeneration across the Spinal Cord Axis within Degenerative Cervical Myelopathy.
Expression of actinin-4 showed a positive correlation with delayed cervical lymph node metastasis. Disease-free survival was significantly lower in patients who were positive for expression of actinin-4 (p=0.010); overall survival showed no difference between patients with or without expression of actinin-4, however. The results revealed that actinin-4 was an independent prognostic factor for disease-free survival. selleck chemicals llc Expression of actinin-4 showed a 73% sensitivity and 68% specificity for prediction of delayed cervical lymph node metastasis. In conclusion, actinin-4 may potentially be a useful biomarker for prediction of delayed cervical lymph node metastasis.Alveolar bone grafting is routinely performed in repair of alveolar clefts. When the alveolar cleft is wider than 11 mm, however, the survival rate of the bone graft and prognosis are poor. Here, we describe successful orthodontic treatment using interdental distraction osteogenesis (IDO) with a tooth-tooth type distractor to reduce the width of the alveolar cleft in a patient with unilateral cleft lip and palate. The patient was a 12-year-old girl with unilateral cleft lip and palate, maxillary dentition midline deviation, congenitally missing maxillary lateral incisors, a palatally-displaced right upper first premolar, a wide alveolar cleft (20 mm), and mandibular prognathism due to maxillary hypoplasia. Treatment comprised a combination of orthodontic treatment and IDO. After treatment, appropriate occlusion, space closure in the maxillary arch, coincidence of the maxillary and facial midlines, and incorporation of the right maxillary first premolar into the arch were obtained. These results suggest that IDO is effective in treating cleft lip and palate patients with a wide alveolar cleft.The purpose of this study was to investigate the relationship among the waist-to-height ratio (WHtR) and the body mass index (BMI) as obesity indicators and gingival inflammation as determined by bleeding on probing (BOP). The participants comprised employees of a milk products company based in Tokyo, Japan. A total of 159 non-diabetic men aged 40 to 59 yr and with a minimum of 28 teeth were included. Multiple logistic regression analysis controlling for age, smoking status, pocket depth, frequency of daily brushing, frequency of weekly interdental brushing, and regular dental attendance was performed to compare the relationships among the obesity indicators and BOP. Participants with good oral hygiene had significantly less BOP than those with poor oral hygiene (p less then 0.001). No significant differences were observed among the other items investigated. A significant association was observed between WHtR and BOP (odds ratio 2.40, 95% confidence interval 1.11-5.22); no such association was observed with the BMI, however. The present results showed that obesity, as determined according to a visceral fat index, was associated with BOP, but not with BMI. This suggests that the WHtR is a more accurate index of obesity than the BMI in studies on BOP.Victim identification following disasters is an important task for the dentist. Use of records of previous dental treatment proved effective in victim identification after the crash of Japan Airlines Flight 123 in 1985. This dental identification procedure can be problematic, however. In exceptional cases, the victim may have had very little or no prior treatment, making identification by this means impossible. The purpose of this study was to establish a new method of dental identification based on morphological comparison of the oral cavity, rather than on evidence of prior dental treatment. This new method involves superimposing 3-dimensional (3-D) models created by digital impression-taking devices, use of which is becoming increasingly widespread in present-day dental treatment. A total of 75 dental models were used to obtain 3-D models. These were then used in a total of 77 superimposition tests. The results demonstrated that the degree of similarity was 98.03－41.30%, and the degree of difference 0.17－29.69%. This indicated that differences among the dental models could be identified with 100% precision. Personal identification by superimposition of such 3-D models offers a useful tool that could compensate for the shortcomings of standard dental identification.We report a case of suspected reinfection with the mumps virus in an elderly patient which resulted in temporary closure of an inpatient ward. A 65-year-old man with colorectal cancer was admitted to the digestive surgery ward at our hospital to undergo a stoma closure operation. He was subsequently referred to our department with right swelling in the preauricular region on postoperative day 4. The swelling subsided within a few days, and the patient was discharged. A serum titer test revealed a high level of antibodies to the mumps virus, however. Therefore, staff who had come into close contact with the patient were examined and the decision taken to stop admitting new patients to the ward. When symptoms are detected in a patient has already had mumps, it is important to consider the possibility of reinfection. Furthermore, it is necessary for medical workers to undergo a serum antibody test to the mumps virus and receive a further vaccination if antibody levels are too low to confer immunity.Dental treatment improves the experience of eating by healing illnesses in the oral cavity or through the installation of special devices. However, mastication can often prove difficult for short periods of time after dental treatment, potentially limiting the types of food that can be consumed. Therefore, we proposed a highly nutritious meal strategy for dental outpatients (hereafter, "easy-to-eat meals"). We previously reported patients' subjective assessment of these easy-to-eat meals as determined through a questionnaire survey. The purpose of the present study was to investigate how differences in age affected such assessments. The study participants comprised patients scheduled to undergo dental treatment. They were divided into 2 groups one of patients aged above and one of those aged below 70 years. All were required to consume provided easy-to-eat meals at the dental hospital directly after treatment and then answer a questionnaire. The questionnaire included items on patient satisfaction with the meals, taste, portion size, convenience, reduction in discomfort, and whether they would consume them again.
