Studies of ventricular depolarization with multichannel recording technics permit detailed three dimensional analysis of the process. Activity commences on the mid left septal surface, followed by activity on the right septum. Rapid endocardial excitation follows and leads to endoepicardial activation of the walls. The latest areas activated are in the basal septum. These findings are related t...

Non-puerperal uterine inversion is an extremely rare gynaecological event that is usually associated with uterine tumours such as submucous or cervical leiomyomas. In this report, we describe a case of uterine inversion due to a large submucous leiomyoma in a 42-year-old multiparous and obese Caucasian woman.

ADIFFERENCE has been observed in certain instances between the onset of QRS in intracavitary and surface limb leads. Simultaneous tracings demonstrate that when premature ventricular depolarization exists the early rapid growth in magnitude of potential recorded by intracavitary leads may be nearly or totally inapparent in surface leads. Following premature depolarization changes occur in intra...

Adjusting input-output gain is crucial for information processing by the brain. Gain control of subthreshold depolarization is commonly ascribed to increased membrane conductance caused by shunting inhibition. But contrary to its divisive effect on depolarization, shunting inhibition on its own fails to divisively modulate firing rate, apparently upsetting a critical tenet of neural models that...

This pilot study examined changes in parenting skills and child behavior following participation in an online positive parenting skills program designed for young children with traumatic brain injury (TBI). Thirty-seven families with a child between 3 and 9 years of age who sustained a moderate to severe TBI were randomly assigned to one of two interventions: online parenting skills training (n...

profound bradycardia during eye surgery is a potentially serious event. in clinical practice oculo-cardiac reflex (ocr) is most often encountered during squint surgery. the objective of this study was to assess the occurrence of ocr and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent ocr. this study comprised 90 patients (aged 4-10 years...

The evaluation of graft function at various stages after transplantation is relevant, particularly at the moment of organ harvest, when a decision must be made whether to use the organ. Autofluorescence spectroscopy is noninvasive technique to monitor the metabolic condition of a liver graft throughout its course, from an initial evaluation in the donor, through cold ischemia transportation, to...

Radiofrequency Ablation of AV node with permanent pacemaker has been used to achieve rate control in persistent symptomatic atrial fibrillation. Although RF Ablation is safe, complications may occur in up to 3% of the procedures. A rare complication of 2nd degree skin burn at indifferent electrode site has been described here. This report highlights the rare but possible complication in patient...

The association between prolonged donor warm ischemia time and poor early graft function has been challenged, but with little evidence. We intend to remove ambiguities and present evidence from the current literature. All donor surgeons must strive to limit warm ischemia to reduce poor early graft function and improve long-term outcomes.
