The aims of this study were to evaluate gastric antral mechanical behavior and distension-induced sensorimotor responses in the human gastric antrum using transabdominal ultrasound scanning. Ten healthy volunteers underwent volume-controlled ramp inflation of a bag located in the antrum with volumes up to 125 ml. The active and passive circumferential tensions and stresses were calculated from ...

Inflation and oesophageal pressures were recorded simultaneously during bag and mask resuscitation of 9 asphyxiated babies. After half a minute of standard inflation pressures, higher pressures were applied for at least 5 inflations by occluding the blow-off valve. No air entered the oesophagus until a high mean inflation pressure of 5.4 kPa was exceeded. These findings were confirmed in 4 fres...

Purpose: to analyze the results of complicated cataract phacoemulsification with implantation various types intraocular lenses and fixation techniques. Material methods. 48 patients (51 eyes) cataracts weakened ligamentous apparatus lens or intraoperative rupture posterior capsule were divided into two groups: study group I consisted 21 (23 eyes, aged 71.4 ± 4.5 years) who had an RSP-III IOL wh...

BACKGROUND/AIMS External anal sphincter (EAS) and puborectalis muscle (PRM) play important role in anal continence function. Based on length-tension measurement, we recently reported that the human EAS muscle operates at short sarcomere length under phys-iological conditions. Goal of our study was to determine if PRM also operates at the short sarcomere length. METHODS Length-tension relation...

Air medical transport of patients suffering of highly infectious diseases is typically performed employing portable isolation chambers. Although the likelihood of decompression flight emergencies is low, sustainability of the devices used is crucial. When a standard isolation unit was subjected to an explosive cabin decompression of 493 hPa, simulating a 32808 ft flight level accident, leak tig...

hroughout the latter half of the twentieth century, a series of disruptive innovations and hotly debated issues resulted in general consensus for standard cataract surgery and agreement on the ideal anatomic location for intraocular lenses (IOL); namely, within the capsular bag. Sir Harold Ridley envisioned this outcome from the inception of the IOL, stating “...the site for the prosthesis shou...

A NEW pupil expansion ring can greatly facilitate phacoemulsification in eyes with small pupils, including those with weak zonules, according to the device’s developer, Boris Malyugin MD PhD, S Fyodorov Eye Microsurgery Complex, Moscow, Russia. The pupillary ring uses the scroll principle to capture and expand the iris margin.The device is composed of 5-0 polypropylene and is square in shape. I...

Cataract surgery transformed radically this past century. From cocaine topical anesthesia, immobilized patients, and extracapsular technique on ‘ripe’ cataracts we advanced to retrobulbars, sutured incisions, and intracapsular technique. Today’s techniques recapitulate those of old, with topical anesthesia and intact capsular bag support of implants enabling virtually instant visual recovery, m...

Subluxated cataracts secondary to blunt injury are a challenge to treat from the construction of rhexis to IOL insertion. For that reason, we designed a new glued endocapsular ring (ECR)/ segment (ECS) for subluxated cataracts and IOLs for sutureless fibrin glue assisted trans-scleral fixation of the capsular bag. The glued ECR/segment stabilizes the capsular bag intra and post-operatively, all...

“It is undoubtedly the final frontier of cataract and refractive surgery.There is great interest and excitement in this field of research at the moment and we are seeing some very interesting approaches coming on stream which hold great promise for future treatment of presbyopia,” said David Spalton FRCS, FRCOphth, who co-chaired the symposium. Dr Spalton said it was important to remember that ...
