In recent years, treatment using implants has become common. Since 2016, dental implants have been insured as part of strengthening health insurance coverage. Consequently, the demand for implants is increasing. Accordingly, the importance of implant maintenance has been emphasized. Of which, implant retrievability is an important factor in implant success. Although the screw-retained type is an advantageous easy-to-retrieve prosthesis, an occlusal point cannot make it to the central axis of the implant. Thus, we aimed to introduce an implant setting method (screw hole indexing) that enables the maintenance of the proper occlusal point and enables retrievability by marking the screw holes of the implant.

The incidence of intracranial complications of otitis media, including lateral sinus thrombophlebitis, has been significantly reduced since the advent of antibiotics. This entity is rarely encountered in clinical practice, and delay in its diagnosis and institution of appropriate therapy may lead to serious, or even fatal, consequences. The signs and clinical course of lateral sinus thrombophlebitis are non-specific and the final diagnosis rests upon radiological investigations including CT-scans and MRI. We have experienced a case of middle fossa and posterior fossa epidural abscess formation, lateral sinus thrombophlebitis that has developed secondary chronic otitis media with cholesteatoma in a 47 year-old female patient. We report this case which was successfully treated by middle fossa dura and posterior fossa dura drainage, lateral sinus thrombectomy with open mastoidectomy.

Subperiosteal abscess of the mastoid region and Bezold's abscesses have become very rare since introduction of antibiotics. Subpriosteal abscess is usually seen in children who have acute mastoiditis. Its occurrence in adults or in associated with chronic otitis media is even more unusual. Bezold's abscess, a complication of acute otitis media in adult who has well pneumatized air cells in the tip of the mastoid, is also rarely seen in the current era of antibiotics. This paper reports a case of postauricular subperiosteal and Bezold's abscess complicating chronic suppurative otitis media with cholesteatoma in a 37-year old woman with review of literatures.

We present an adult female patient who developed irreversible paraplegia and areflexia four days post intrathecal chemotherapy with methotrexate, cytosine arabinoside and hydrocortisone. On magnetic resonance imaging (MRI) of the lumbar spine, diffuse gadolinium enhancement of the anterior spinal nerve roots (ventral roots) was detected. Methylprednisolone was intravenously administered at a daily dose of 30mg/kg for three days. Despite this treatment, flaccid weakness in the lower extremities and urinary retention persisted. Following consolidation chemotherapy, no improvement in neurologic status was noted. Six months later, a follow-up MRI revealed severe atrophy of the thoracic spinal cord.

OBJECTIVES: This study was conducted to investigate the status and need for nutrition and dietary life education among nutrition teachers at schools. These characteristics were analyzed if they were different between elementary schools and middle-high schools. METHODS: Subjects were 151 nutrition teachers from 70 elementary schools, 41 middle schools and 40 high schools in 17 cities nationwide selected by two-stage stratified cluster sampling process. Survey questionnaires included the items on general characteristics, status and need assessment for nutrition and dietary life education. Chi-square test or t-test was used for data analysis by school groups. RESULTS: Nutrition education was implemented at 65.7% of elementary schools and 51.9% of middle-high schools. Nutrition education was mainly performed in 'discretionary activities·extracurricular activities' at elementary school and through 'newsletters, school homepage, foodservice bulletin board' at middle-high school (p<0.001). The most needed topic for nutrition education in nutrition teachers was 'healthy dietary habits and table manners' and this was not significantly different by school groups. Responses on adequate frequency (p<0.01), methods used for nutrition education (p<001), materials for nutrition education (p<0.001), information sources for nutrition education (p<0.001) were significantly different by school groups. Major tasks for activating nutrition education included 'securing the time for implementing nutrition education by reducing work loads' and 'developing standardized nutrition education materials' in schools. CONCLUSIONS: Nutrition education at schools might be activated by improving working conditions of nutrition teachers and developing the practical programs that reflect the needs of nutrition teachers.

BACKGROUND: Complex regional pain syndrome (CRPS) involves severe pain and it is difficult to identify the exact cause or pathogenesis. Therefore, there are controversies regarding legal issues related to the establishment of damage in medical malpractice lawsuits involving CRPS. This study aimed to analyze malpractice lawsuits involving CRPS, which occurred after the disputed medical treatment, to provide information on the courts' opinion and characteristics of the cases. METHODS: This study analyzed 23 lawsuit judgments involving CRPS that were sentenced from 2005 to 2015. RESULTS: A total of 12 of the 23 cases were partially ruled in favor of the plaintiff. The average amount (KRW) claimed was 470,638,385 ± 860,634,092 (21,000,000 to 4,020,000,000), and that awarded was 72,906,843 ± 53,389,367 (15,000,000 to 181,080,803). Sixteen of the 23 cases had CRPS type I. In 11 of 23 cases, the site of the pain was located in the lower limb and in 14 cases there was no presence of trauma or event prior to medical treatment. CONCLUSION: Nerve injury was the most frequent reason for taking responsibility in compensating damage in malpractice cases involving CRPS. Physicians should consider various possibilities of such complications in medical practices. It is important to identify and improve areas which need to be improved for patient safety through analyzing the lawsuit judgment cases.
