Angiosarcoma is an uncommon malignancy, which spread out from the endothelial cells of vessels. Scalp angiosarcoma with cervical lymph node metastasis is particularly rare. This article describes a rare case of angiosarcoma of the scalp, presenting as neck inflammation. Imaging procedures such as computed tomography (CT), magnetic resonance image (MRI) and ultrasonography (US) were not sufficient to diagnose this case. A needle biopsy provided an effective and accurate diagnosis of cervical lymph node metastasis. Additional observation and physical examination was required to diagnose the origin of the primary cancerous lesion. Once the angiosarcoma diagnosis was confirmed histologically, sequential weekly and monthly docetaxel (DTX) treatment was effective in preventing reoccurrence. Nonetheless, the optimization of angiosarcoma treatment remains a future goal. Although patients generally describe pain and swelling at the primary lesion site, this patient complained only of painful neck inflammation, without any indication of pain or swelling of the scalp. A revised diagnostic protocol should note that cervical lymph node metastasis of unknown primary origin may result from angiosarcoma of the scalp.

音韻情報や言語情報を扱う作動記憶である音韻的作動記憶の障害は、ダウン症児・者の問題のひとつであり、音韻的作動記憶の問題がダウン症児・者の言語発達の遅れの重要な規定要因となりうることが主張されている。ダウン症児・者の音韻的作動記憶の機序や特徴を明かにすることは、言語発達の遅れが重篤であるとされるダウン症児・者への援助の手立てを考える上で、重要な教育心理学的課題であり、実証的な検討が求められている。そこで本研究では、ダウン症児・者の音韻的作動記憶の特徴を明かにすることを目的とした。・・・

Local migration of the seismic activity before and after the great Sanriku earthquake of March 3, 1933 in northern Japan is described. This remarkable migration pattern in the most active seismic zone in the world is compared with that of the Anatolia earthquakes accompanied by successive development of a great faulting system. The global migration of the epicentral regions of the greatest earthquakes during the last 30 years is summarized. The two northward migration branches in the western part of the circum-Pacific belt and in the Sumatra-Burma-Kansu-Baikal seismic zone and the one southward branch in the south-eastern part of the circum-Pacific belt, which are confirmed by certain evidence, suggest a clockwise rotational migration pattern in the circum-Pacific belt and the surrounding area or a worldwide migration pattern from the equatorial region to the pole regions. These migration patterns may provide an important suggestion on the mechaism of earthquake generation.|地震の震源域が時間と共に系統的に移動する場合があるかどうかという問題は,地震の発生を予測する問題にも関連して,古くから多くの人によって論じられてきた.余震域の拡大の様な,比較的短期間の局地的な移動については,2,3のかなり明瞭な移動の例が報告されているが,最も興味ある所の大きい地震の大規模な移動に関しては,これまでいくつかの報告例があるにも拘らず,その資料は,移動を結論するには不十分な場合が多く,移動が確実に結論され得る例は非常に少ない.従って,この問題については,確実に震源域の移動を結論出来る例を出来るだけ多く見出して,その移動特性を明らかにすることが重要である.本論文では,次に述べる,1933年3月3日の三陸沖大地震前後約6年間の移動及び過去30年間の巨大地震の震源域の世界的規模における移動について論ずる.

To study the process of occurrence of shallow earthquakes in and near Japan, the space and the time distributions of focal regions of large earthquakes and the earthquake energy density during the period (1885-1968, May) have been investigated. The results are summarized as follows: (1) During the last eighty years, earthquakes occurred with the space distribution showing a close relation to tectonic structures of this region. (2) Great earthquakes in this region occurred to fill gaps of seismic activity of thirty years and over, as pointed out in other circum-Pacific regions. It is particularly remarked that any large earthquakes of magnitude 7 and over did not occur in the focal regions of great earthquakes during the preceding period. (3) The seismic activity in the Kwanto and the southern Tohoku districts, including the part of the outer seismic zone, is abnormally low in the last thirty years. If the high activity in the preceding fifty years in this region is considered, this result suggests a possibility that great events may occur in the region in the near future.|日本及びその周辺の地震活動の空間的分布並びにその時間的変化を,マグニチュード7以上の大きい地震の震源域の分布及び小さい地震を含めた地震エネルギー密度の分布から論じた.できるだけ長期間についてしらべることがのぞましいが,この目的のための地震資料は,1885年以降に限られる.この最近約80年間についての調査の結果を次に要約する

Spontaneous pneumothorax is most common in adolescents and young adults. Some of them develop contralateral pneumothorax. In this paper, we report the case of a patient with spontaneous contralateral pneumothorax, whose body mass index (BMI) was 18.8 kg/m2. For either chest physicians or thoracic surgeons, follow up with recognition of increased risk of the contralateral pneumothorax is important especially in patients with contralateral bullous lesions and low BMI.

Measuring the interstitial water pressure of debris flows under various conditions gives essential information on the flow stress structure. This study measured the basal interstitial water pressure during debris flow routing experiments in a laboratory flume. Because a sensitive pressure gauge is required to measure the interstitial water pressure in shallow laboratory debris flows, a differential gas pressure gauge with an attached diaphragm was used. Although this system required calibration before and after each experiment, it showed a linear behavior and a sufficiently high temporal resolution for measuring the interstitial water pressure of debris flows. The values of the interstitial water pressure were low. However, an excess of pressure beyond the hydrostatic pressure was observed with increasing sediment particle size. The measured excess pressure corresponded to the theoretical excess interstitial water pressure, derived as a Reynolds stress in the interstitial water of boulder debris flows. Turbulence was thought to induce a strong shear in the interstitial space of sediment particles. The interstitial water pressure in boulder debris flows should be affected by the fine sediment concentration and the phase transition from laminar to turbulent debris flow; this should be the subject of future studies.
