Abstract

Interplate megathrust earthquakes have inflicted catastrophic damage on human society. An extremely hazardous megathrust earthquake is predicted to occur along the Nankai Trough off southwestern Japan, an economically active and densely populated area with historical records of megathrust earthquakes. Megathrust earthquakes are the result of a plate subduction mechanism and occur at interplate slip-deficit (or coupling) regions. Many past studies have attempted to capture slip-deficit rate (SDR) distributions for assessing future earthquake disasters. However, they could not capture a total view of the megathrust earthquake source region because they had no seafloor geodetic data. The Hydrographic and Oceanographic Department of the Japan Coast Guard (JHOD) has been developing a highly precise and sustainable seafloor geodetic observation network deployed in this subduction zone to broadly obtain direct information related to offshore SDR. Here, we present seafloor geodetic observation data and an offshore interplate SDR distribution model. Our data suggests that most offshore regions in this subduction zone have positive SDRs. Specifically, our observations indicate previously unknown high-SDR regions that are important for tsunami disaster mitigation and low-SDR regions that are consistent with distributions of shallow slow earthquakes and subducting seamounts. This is the first direct evidence suggesting that coupling conditions are related to these seismological and geological phenomena. These observations provide new fundamental information for inferring megathrust earthquake scenarios and interpreting research on the Nankai Trough subduction zone., Comment: main article 14 pages, methods 10 pages, supplementary tables 23 pages

14. Seafloor crustal deformation data along the subduction zones around Japan obtained by GNSS-A observations

Abstract

Crustal deformation data obtained by geodetic observation networks are foundations in the fields of geodesy and seismology. These data are essential for understanding plate motion and earthquake sources and for simulating earthquake and tsunami disasters. Although relatively scarce, seafloor geodetic data are particularly important for monitoring the behaviour of undersea interplate boundary regions. Since the mid-1990s, we have been developing the combined Global Navigation Satellite System-Acoustic ranging (GNSS-A) technique for realizing seafloor geodesy. This technique allows us to collect time series of seafloor crustal deformation. Our published data can be used to investigate several seismological phenomena along the subduction zones around Japan, namely the Nankai Trough, Sagami Trough and Japan Trench. These regions are globally important places in geodesy and seismology and are also suitable for comparison with other geophysical datasets. Our intention is for these data to promote further understanding of megathrust zones., Comment: 16 pages, 6 figures, 4 tables

19. 3D morphological changes of the lip and face in patients with cleft lip and alveolus: The comparison of the lip development of incomplete and complete cleft lips under 3 months of age.

Author

Abstract

To treat cleft lip and palate, it is critical to understand the development of the lips and face. Objective: The objective of this study is to comprehend the development of lips and facial features in patients with cleft lip from birth to cheiloplasty. A comparison of incomplete and complete cleft lips was performed. Methods: The morphology of the lips and face was recorded using a noncontact three‐dimensional morphology recorder from shortly after birth to cheiloplasty. For each patient, their soft tissue growth was analyzed. Results: These findings suggest that an incomplete cleft widens the gap between healthy and affected sides from 2 to 3 months of age. The pattern is different from that of a complete cleft. [ABSTRACT FROM AUTHOR]

Abstract

Masses on the tongue base are rare and include malignant tumors, benign tumors, cysts, ectopic thyroid glands, and hamartomas. If the masses are enlarged, upper airway obstruction may occur. Hamartomas of the base of the tongue have been rarely reported, and there have been no reports of hamartomas associated with dyspnea beginning in the neonatal period. We present the case of a 14-year-old boy who had a tongue base mass since birth and was managed with a tracheal cannula. An absence of the lingual frenulum and impaired tongue movement were also observed. The mass was behind the base of the tongue and could not be observed intraorally but only on endoscopy. Computed tomography and magnetic resonance imaging showed a 24 × 21 × 32 mm lesion extending from the base of the tongue to the pharynx. Under the diagnosis of a benign tumor at the tongue base, a mass reduction surgery with biopsy was performed at the tongue base under general anesthesia using an intraoral approach. The result of the pathological examination was tongue hamartoma. The postoperative course was uneventful, and the tracheal cannula was removed 4 months after the operation under hospitalization. We also review previous cases of hamartomas of the tongue base with and without complications. [ABSTRACT FROM AUTHOR]

Abstract

Isomura E.T., Fujimoto Y., Matsukawa M., et al. General Factors and Dental-Related Risk Factors for Postoperative Pneumonia or Infectious Complications: A Retrospective Study. Journal of Clinical Medicine 12, 3529 (2023); https://doi.org/10.3390/jcm12103529., Numerous studies report that perioperative oral care decreases the frequency of postoperative pneumonia or infection. However, no studies have analyzed the specific impact of oral infection sources on the postoperative course, and the criteria for preoperative dental care differ among institutions. This study aimed to analyze the factors and dental conditions present in patients with postoperative pneumonia and infection. Our results suggest that general factors related to postoperative pneumonia, including thoracic surgery, sex (male > female), the presence or absence of perioperative oral management, smoking history, and operation time, were identified, but there were no dental-related risk factors associated with it. However, the only general factor related to postoperative infectious complications was operation time, and the only dental-related risk factor was periodontal pocket (4 mm or higher). These results suggest that oral management immediately before surgery is sufficient to prevent postoperative pneumonia, but that moderate periodontal disease must be eliminated to prevent postoperative infectious complication, which requires periodontal treatment not only immediately before surgery, but also on a daily basis.
