Paraesophageal hiatus hernia represents a rare hiatal hernia that are treated surgically. The completely asymptomatic paraesophageal hernia often does not reach the clinician or surgeon. But the presence of a symptomatic paraesophageal hernia is sufficient indication for surgery. The paraesophageal hernia may be approached either transthoracically or transabdominally. The general technique is essentially the same, whichever route is used. From either transthoracic or transabdominal approach, following reduction of the viscus and elimination of the sac, the diaphragmatic opening is then closed with interrupted heavy dacron or silk sutures in paraesophageal hiatus hernia. But if the phrenoesophageal membrane often is destroyed when the esophagogastric junction and the distal esophagus have been mobilized, it becomes important to fix the esophagogastric junction below the diaphragm, so that it does not slide through the hiatus and produce a sliding-type hiatus hernia in future. We have experienced one case of paraesophageal hiatus hernia which was accompanied with severe anemia in child. We preferred to approach through left thoracotomy incision and then pushed down the stomach into the abdominal cavity with complete excision of the hernial sac. We employed Belsey Mark V procedure using of Teflon felt pledgets with the mattress sutures against development of sliding-type hiatus hernia in postoperative period. postoperative course has been uneventful and good for about 3 months to this time.

Sacral nerve stimulation through the retrograde approach has been used for peroneal or irritable bowel syndrome through the retrograde approach. However, several reasons, lead could not be advanced down ward. In this case, anterograde sacral nerve stimulation through the sacral hiatus could be used. The aim of this report is to present of technique of sacral nerve root stimulation through the sacral hiatus approach.

대기 중 이산화탄소 등의 농도가 지속적으로 증가하고 있음에도 최근 10여 년 동안(2002-현재) 전지구 지표 온도는 거의 답보상태에 머물러 있다. 이처럼 온실기체 강제력에도 불구하고, 지구 온난화 경향이 사라진 듯 보이는 현상을 지구 온난화 멈춤(hiatus)이라 한다. 이 연구는 HadGEM2-AO가 모의한 RCP8.5 시나리오 실험(95년간) 자료를 분석하여, 온난화 멈춤 시기의 특징을 분석하였다. 온난화 멈춤 기간을 나타내는 시계열은 동서 평균한 연직 해수 온도 분포를 EOF 분석하여 구한 두 번째 PC (PC2)로 정의하였다. PC2를 이용하여 온난화 멈춤과 엔소와의 관련성, 기후시스템의 변화 등을 분석하였다. 라니냐 지수(NINO3지수에 -1을 곱하여 정의)가 PC2를 약 11개월 앞서는 것으로 보아 라니냐 발생이 온난화 멈춤을 유도할 수 있음을 발견하였다. 또한 기후시스템의 냉각은 해수 표층의 열이 해양 내부로 침강으로 나타남을 보였다. 이는 해양의 열흡수에 의해 전지구 온도 상승률이 약화되었음을 의미한다. 온난화 멈춤 시기에 북태평양과 북반구 극지는 양의 온도 편차가 나타났으며, 열대 해양에서는 무역풍이 강화되었다.

This paper deals with the reduction of unstressed prevocalic /u/ and the appearance of /w/ which are observed in such words as ambiguity [ˌæm bǝ ˈgju: ǝ ti] - ambiguous [æm ˈbɪ gjǝ wǝs]. This phenomenon is recorded in Merriam-Webster Online Dictionary, Webster's Third New International Dictionary, Unabridged, and the draft revisions of Oxford English Dictionary Online. Since this phenomenon has not been studied in detail up to now, this paper aims 1) to collect the data related to the reduction of unstressed prevocalic /u/, 2) to classify them systematically, and 3) to explain the phenomenon in terms of Optimality Theory. In the course of analysis, Prevocalic Lengthening, which is crucial to the preservation of unstressed prevocalic /u/, is reinterpreted as one of the ways to prevent hiatus (annual /æ nju: ǝl/). /w/-insertion is another way to prevent hiatus (annual /æ njǝ wǝl/). In addition it is argued that prevocalic /u/ behaves differently from prevocalic /i/ due to the difference in the articulators involved.

This is a report of a case of congenital esophageal hiatus hernia, occurring in a younger child at the age of one year and two months. The child was suffered from vomiting (intermittently coffee-ground vomitus or blood-flecked vomitus), coughing, and high fever for about 3 months.Diagnosis was confirmed by the radiologic barium study of the gastrointestinal tracts. The herniated organs were entire stomach and a part of the transverse colon. They were located in the right chest. The etiologic pathology was mainly congenital developmental defect of the musculature of the diaphragm, forming the posterior margin of the esophgeal hiatus, and additionally slight shorted esophagus. After reduction of herniated organs back to the abdominal cavity through abdominal approach, herniorrhaphy was performed through transthoracic approach with modified Allison's procedure. At the same time, any associated anomalies, such as hypertrophic pyloric stenosis, were not seen. Postoperative course was uneventful.

Epiduroscopy is very useful in the treatment of not only low back pain caused by failed back surgery syndrome, epidural scar or herniated disc but also by chronic refractory low back pain which does not respond to interventional conservative treatment including fluoroscopically-directed epidural steroid injections and percutaneous adhesiolysis. Because cauterization using a laser fiber has become recently available, a wider opening is required to enter into the sacral canal in the case of epiduroscopic laser neural decompression (ELND). However, in a few patients, it is difficult to insert a device into the epidural space due to stenosis around the opening, and there is no alternative method. Herein, we report a case where a hiatus rasp specially designed for such patients was used to perform the operation.

Congenital diaphragmatic hernia is an important cause of respiratory distress in the newborn. Eventration, with which these conditions are easily confused, may also Produce severe respiratory distress in infancy or be an asymptomatic radiographic finding. Harrington`s classification of diaphragmatic hernias into two categories, traumatic and nontraumatic, is most widely accepted. Nontraumatic hernias are [1] the congenital types, composed of the posterolateral [Bochdalek], those through the esophageal hiatus, the parasternal [/Morgagni], and those through a defect left by partial absense posteriorly, and [2] the acquired types, composed of those through the esophagea/hiatus [sliding and paraesophageal] and those the sites mentioned above under the congenital hernias. During the period from 1970 up to October 1978, 21 cases of diaphragmatic hernia were treated in department of cardiovascular and thoracic surgery. 11 cases of Bochdalek hernias, 1 case of Morgagni hernia, 5 cases of diaphragmatic eventration and 3 cases of hiatal hernia [2 cases of paraesophageal and 1 cases of sliding type], were experienced. 3 cases of 20 died of respiratory insufficiency, 2 cases of mortality were combined with left lung hypoplasia with Bochdalek hernia.

We divide the timeline of the history of Finsler geometry, which dates back to Riemann's inaugural lecture in 1854, into three periods (hibernation, hiatus, rebirth) and we study formation of Romanian Finsler school around Iasi, Romania during the hiatus period. We look for the history centered around Radu Miron who is a third generation geometer of Iasi University and the mathematical heritage there through five generations. We also investigate mathematical impact of T. Levi-Civita, D. Hilbert, ${\acute{E}}$ Cartan who are considered as top mathematicians at their time.

Background: Caudal block is a common technique in children for reducing postoperative pain, and there have been several reports on the variations of the sacral canal in children. However, previous studies have mainly focused on the needle trajectory for caudal block, and there is limited information on the structural variations of the sacrum in children. The purpose of this study was to analyze the anatomic variations of sacral canals in children. Methods: Three-dimensional computed tomographic images were analyzed. The data from the images included (1) fusion of the sacral vertebral laminae and the sacral intervertebral space (2) existence of the sacral cornua and (3) the types of sacral hiatus. The types of sacral hiatus were classified into 3 groups: group I (fusion of S3 or S4 vertebral laminae), group II (unfused vertebral arch with the distance of the S3 and S4 vertebral laminae < 50% of the distance between the cornua), and group III (unfused vertebral arch with the distance of the S3 or S4 vertebral laminae ${\geq}50%$ of the distance between the cornua). Results: A total of 143 children were included in this study. All of the sacral vertebral arches were not fused in 22 children (15.4%). Cornua were not identified bilaterally in 5 (3.5%) and unilaterally in 6 (4.2%) children. In the sacral hiatus, group II and group III were identified in 22 (15.4%) and 31 (21.7%) children, respectively. Conclusions: The sacral canal has various anatomical variations in children. Careful attention must be paid to identify the correct anatomic landmark.
