Inhabitant or visitor? Unexpected finding of Aglaophenia (Cnidaria, Hydrozoa) in Antarctic waters

2017

AbstractBenthic hydrozoans are one of the most speciose and characteristic taxa from the Antarctic region, with a high number of endemic species, but diversity at the genus level is low and some families with world wide distribution are unrepresented. This is the case of the family Aglaopheniidae. A new species to science of the genus Aglaophenia Lamouroux has been found in the eastern end of the Weddell Sea, at depths of 65–116 m, within the material obtained by the German Antarctic expedition ANT XV/3. This finding constitutes a new record for the Weddell Sea fauna, the first evidence of the genus for the Polar Regions, and even the family Aglaopheniidae from Antarctic waters. The materia…

HIDROZOOS DE LA FAMILIA AGLAOPHENIIDAE DE LA PLATAFORMA CONTINENTAL Y TALUD SUPERIOR DEL CARIBE COLOMBIANO

2016

A taxonomic study of hydroids of the Aglaopheniidae family collected on soft bottoms of Colombian Caribbean Sea between 20 and 500 m depth in March 2001 was made. Two genera and six species were found, highlighting Aglaophenia elongata, A. lophocarpa and A. tridentata as new records for Colombian waters. Additionally, the bathymetric distribution for Aglaophenia latecarinata and A. tridentata was expanded. In general, morphological characters of the species studied did not show significant differences regarding the taxonomic descriptions made by other authors. This report contains taxonomic files and images of the species described and annotations about general composition, distribution and…

Roux-en-Y Gastric Bypass as an Effective Bariatric Revisional Surgery after Restrictive Procedures

2020

<b><i>Introduction:</i></b> Revisional surgery must be considered when insufficient weight loss is attained or weight is subsequently regained. This study aimed to investigate the value of Roux-en-Y gastric bypass (RYGB) as a revisional procedure after restrictive surgery. <b><i>Materials and Methods:</i></b> An observational, retrospective study including patients initially operated on for morbid obesity with restrictive techniques (vertical-banded gastroplasty [VBG], adjustable gastric band [AGB], and sleeve gastrectomy) and reoperated with RYGB in our centre between December 1994 and January 2019. Demographic and anthropometric data, associ…

Correlation between the visibility of submandibular fossa and mandibular canal cortication on panoramic radiographs and submandibular fossa depth on …

2017

Background To identify a correlation between the submandibular fossa (SF) visibility and mandibular canal (MC) cortication on panoramic image and the depth of SF measured on CBCT and also correlation between the depth of SF and vertical and horizontal location of MC on CBCT. Material and Methods 500 CBCT scans and panoramic radiographs were evaluated. SF depth types were classified as type I ( 3mm) on CBCT. Visibility of SF and the cortication of MC on panoramic radiographs were compared with the depth of SF on CBCT. Distances between MC and mandibular inferior, buccal and lingual cortices were measured. Results No statistically significant correlation was found between radiolucent appearan…

Interpretation of intraoperative parathyroid hormone monitoring according to the Rome criterion in primary hyperparathyroidism

2022

AbstractIntraoperative parathyroid hormone dosage allows real-time monitoring of the decrease in PTH levels during parathyroidectomy and verify procedure’s efficacy. Currently, none of the interpretative criteria used has absolute accuracy. The aim of this study is to evaluate diagnostic accuracy of the Rome criterion verifying diagnostic significance of the individual assays. A total of 205 patients with primary hyperparathyroidism from a single adenoma were retrospectively evaluated and monitored with baseline PTH, PTH at 10 min and PTH at 20 min after adenoma excision. The accuracy of the latter two assays compared with baseline was compared by ROC curves. In addition, was evaluated the …

Anaesthetic techniques to prevent perioperative stroke.

2013

Different techniques and interventions that can be used by an anaesthesiologist to minimize the perioperative stroke risk are summarized.The most important risk factors for perioperative stoke are not modifiable, for example previous stroke or renal failure, but they can be used to identify patients with a high risk for perioperative stroke. The antiplatelet therapy should be continued in patients with a high risk for cardiovascular thrombosis. This might be true even for operations in which bleeding should be strictly avoided such as eye surgery. One of the most recent neuroprotective approaches is the remote ischaemic preconditioning.Perioperative stroke increases morbidity and mortality …

Pre- and intraoperative methods of controlling cerebral circulation in giant aneurysm surgery.

1995

The surgical treatment of giant aneurysms usually requires temporary clipping of the aneurysmatic vessel. In planning the surgical approach and in applying temporary clips, the surgeon must consider collateral circulations. The functional integrity of the collateral vessels frequently decides the patient's outcome. In 8 patients with internal carotid artery giant aneurysm, measurements of blood flow velocities in the ipsilateral middle cerebral artery were performed preoperatively with transcranial Doppler ultrasound (TCD) during manual occlusion of the carotid artery at the neck. Three different perfusion patterns were established, and each collateral capacity was rated as insufficient, te…

The Fontan-Operation: From Intra- to Extracardiac Procedure

2003

Purpose For treatment of univentricular heart, the Fontan operation has been established as the definitive palliation. The current controversy is mainly based on the high incidence of arrhythmias after an intra-atrial lateral tunnel Fontan operation. Methods From January 1995 until April 2002. 46 children underwent a Fontan-type operation with or without a small fenestration. In 33 patients (group I) an Intracardiac tunnel and in 13 patients (group II) an extracardiac conduit procedure was performed. Principal findings There was no perioperative mortality. All patients showed postoperative a significant increase of arterial oxygen saturation, from 76 to 86% after surgery with fenestration, …
