The digital workflow of optical impressions by the intraoral scanner and CADCAM manufacture of dental prostheses is actively developing. The complex process of traditional impression taking, definite cast fabrication, wax pattern making, and casting has been shortened, and the number of patient’s visits can also be reduced. Advances in intraoral scanner technology have increased the precision and accuracy of optical impression, and its indication is progressively widened toward the long span fixed dental prosthesis. This case report describes the long span implant case, and the operator fully utilized digital workflow such as computer-guided implant surgical template and CAD-CAM produced restoration after the digital impression. The provisional restoration and customized abutments were prepared with the optical impression taken on the same day of implant surgery. Moreover, the final prosthesis was fabricated with the digital scan while utilizing the same customized abutment from the provisional restoration. During the data acquisition step, stl data of customized abutments, previously scanned at the time of provisional restoration delivery, were imported and automatically aligned with digital impression data using an ‘A.I. abutment matching algorithm’ the intraoral scanner software. By using this algorithm, it was possible to obtain the subgingival margin without the gingival retraction or abutment removal. Using the digital intraoral scanner’s advanced functions, the operator could shorten the total treatment time. So that both the patient and the clinician could experience convenient and effective treatment, and it was possible to manufacture a prosthesis with predictability.

A drug interaction can be defined as an interaction between a drug and other drugs that prevent the drug from performing as expected. These processes may include alterations in the pharmacokinetics of the drug, such as modulations in the absorption, distribution, metabolism, and elimination (ADME) of a drug. Alternatively, drug interactions may be the result of the pharmacodynamic characteristics of the drug: the concomitant medication of a receptor antagonist and an agonist for the same receptor. The following interaction may increase or decrease the effectiveness of the drugs or the adverse drug reactions of the drugs. The possibilities of drug interactions should increase as the number of drugs being taken increases in patients. Therefore, patients taking several drugs simultaneously are at the greatest risk for interactions. Drug interactions can contribute to the increasing cost of healthcare because of the costs of medical care that are required to treat problems caused by changes in effectiveness or adverse drug reactions. The drug utilization review (DUR) system has been defined as a structured, ongoing initiative that interprets patterns of drug usage in relation to predetermined criteria and attempts to prevent or minimize inappropriate prescribing. The primary objectives of DUR are to improve the quality of health care for healthcare members and to assist in containing health care costs. In order to achieve these goals, prescription claims must be reviewed both prospectively and retrospectively. The DUR system supplies information to prohibit co-dispensing of contraindicated drugs which increases the risk of drug interactions properly to all the healthcare professionals participating in the care of the patients. In this article, we suggest the importance of DUR in relation to the contraindication of co-medication drugs.

Background: Plastic changes to brain structure and function have been reported in elite athletes of various sports. Interestingly, different regions of the brain were engaged according to the type of sports analyzed. Our laboratory reported no difference in total cerebellar volume of basketball players compared to that in the control group using the manual segmentation method. Further detailed analyses showed that elite basketball players had increased volume of the striatum and vermian lobules VI–VII of the cerebellum. We analyzed the brain magnetic resonance imaging (MRI) of basketball players to understand their cerebral cortical plasticity through automatic analysis tools for MRI. Methods: Brain MRI data were collected from 19 male university basketball players and 20 age-, sex-, and height-matched control groups. In order to understand the changes in the cerebral cortices of basketball players, we employed automated MRI brain analysis techniques, including voxel-based morphometry (VBM) and surface-based morphometry (SBM). Results: VBM showed increased gray and white matter volume in both precentral gyri, paracentral lobules and increased gray matter volume in the right anterior superior temporal gyrus. SBM revealed a left dominant increase in both pericentral gyri. Fractal dimensional analysis showed an increase in the area of both precentral gyri, the left subcallosal gyrus, and the right posterior cingulate gyrus. These results suggest a significant role not only for the primary motor cortex, but also for the cingulate gyrus during basketball. Conclusion Plastic changes of both precentral gyri, the pericentral area, paracentral lobules, and the right superior temporal gyrus were observed in elite basketball players. There was a strong increase of fractal complexity in both precentral gyri and a weak increase in the right posterior cingulate gyrus and left collateral gyrus. In this study, plastic regions linked to functional neuroanatomy were related to the competence required to play basketball.

To fine out the changes of DNA ploidy and cellular proliferation activity during carcinogenesis and evaluate correlation between flow cytometrically determined S-phase fraction and proportion of proliferation cell nuclear antigen(PCNA, PC10) immunoreactive cells, the authors studied on malignant fibrous histocytoma induced by intra-articular injection of 9, 10-dimethy1-1, 2-benzanthracene(DMBA) in the rats. Forty Wistar rats were used. The results obtained were as follows. 1) Firstly, tumors were palpated 5 weeks after the last injection of DMBA and formed in 27 rats at sacrificed. Histologically, these lesions showed storiform, indicative of malignant fibrous histiocytoma. 2) Three cases of DNA aneuploidy were observed at 4 and 5 months after the last injection of DBMA and one of them, which was DNA diploidy at main mass, was found at daughter mass. 3) Flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells in malignant fibrous histiocytoma induced by DMBA were much higher than in control groups and slightly increased according to sequential changes after formation of mass. The comparison of flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells showed significant correlation(r=0.6092, p<0.001). Above results strongly suggest that ploidy pattern may evolve into aneuploid type during the development of tumor and proliferation activity increases during the carcinogenesis.

Cancer care is very complicated, and given the rapidly developing knowledge and technology related to cancer management, multidisciplinary team approach has become essential to determine the optimal treatment plan in an efficient way. It is expected to improve the clinical outcomes in cancer treatment. Multidisciplinary team approach is increasingly implemented across cancer care services throughout the world. In many developed countries, it has been a principle way of managing cancer patients and the organizing multidisciplinary teams has become a mandatory requirement. The team usually includes surgeons, medical oncologists, radiation oncologists, pathologists and also radiologists. In Korea, reimbursing multidisciplinary care for cancer patients has been implemented since August 2014. From short experiences, many practical issues were raised to improve this newly established cancer care service successfully in the current medical system in Korea. This review briefly describes the potential benefits of multidisciplinary team working in cancer care and suggests the several requirements to improve the multidisciplinary care service for the future.

Pachydermodactyly is a rare, distinct form of digital fibromatosis characterized by acquired, asymptomatic, bulbous swellings on the back and side of the proximal phalanges or proximal interphalangeal joint areas of fingers. It occurs mostly in men. There have been many cases treated with intralesional injection of corticosteroids, however, only a few by surgical excision. We report a case of pachydermodactyly, involving both fingers, in a young female. She was treated with surgical excision and recovered, with no sign of sequelae, during a follow-up period of 6 months.

Gastrointestinal cytomegalovirus(CMV) infection in adults is observed as a part of a generalized or localized infection in patients who are immunocompromized. We report a case of CMV infection of the small intestine. The patient is a 34 year-old woman who has complained of palpable purpura in the lower extremities and buttocks, and arthralgia of large joints. The skin biopsy showed fibrinoid necrosis and neutrophils with leukocytoclasis, which findings are compatible with hypersensitivity angiitis. The patient received steroid and cyclophosphamide. During the follow-up period, generalized edema and bloody stool were detected. Resected specimen of small bowel has multiple aphthous ulcer. Microscopically, cytomegalic cells are observed along the endothelial cells and mesenchymal cells. In situ hybridization using DNA probes against CMV revealed positive staining in the cytomegalic inclusions in vascular endothelial and mesenchymal cells.

Duret hemorrhage is characterized by an upper brainstem hemorrhage due to increased intracranial pressure by mass effect such as subdural hematoma or a brain tumor. The anteroposterior elongation and downward displacement of the upper brainstem by transtentorial herniation results in the compression and tearing of the paramedian perforating vessels that feed the upper brainstem tegmentum. The consequent hemorrhage that involves the upper brainstem renders recovery to be almost impossible. Following a tricuspid valve replacement surgery, a 56-year-old woman developed a left fronto-temporo-parietal nontraumatic subdural hematoma resulting in transtentorial herniation of the left mesial temporal lobe. A successful surgical evacuation of the hematoma was done with clinical improvement. Two days later, she was referred to neurology with an aggravated right side weakness, dysarthria, and a newly developed extraocular movement disturbance. A brain CT and MRI showed a pontine hemorrhage. We report a case of pontine hemorrhage, a Duret hemorrhage, after the surgical evacuation of nontraumatic subdural hematoma.
