  • 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.

  • Despite the greenhouse gases like carbon dioxide have steadily increased in atmosphere, the overall trend of the global average surface air temperature has stalled during the last decade (2002-present). This phenomenon is often called hiatus or warming pause, which is challenging the prevailing view that anthropogenic forcing causes warming environment. Our study characterized the hiatus by analyzing the HadGEM2-AO (95 yrs) simulation data based on RCP8.5 scenario. The PC2 time series from the EOF of the zonal mean vertical ocean temperature has been defined as the index that represents the warming pause. The relationship between the hiatus, ENSO and the changes in climate system are identified by utilizing the newly defined PC2. Since the La Nina index (defined as the negative of NINO3 index) leads PC2 by about 11 months, it may be possible that the La Nina causes the warming to be interrupted. We also show that the cooling of the climate system closed tied to the heat penetration into the deep ocean, indicating the weakening the warming rate is due to the oceanic heat uptake. Finally, the global warming hiatus is characterized by the anomalous warming in Arctic region as well as the intensification of the trade wind in the equatorial Pacific.

  • 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.
