Mannan oligosaccharide prepartum supplementation: effects on dairy cow colostrum quality and quantity.

Providing the neonatal calf with a sufficient quantity and quality of colostrum may optimise future health, performance and reduce the risk of morbidity. A 6-month double blind trial with 80 prepartum dairy cows was conducted to determine if supplementation with mannan oligosaccharide (MOS) influences colostrum quality, quantity and subsequent calf performance. The Holstein cross Friesian 80 cows (no heifers) were allocated into a control and treatment group at the point of drying off by previous lactation number and yield.

Corpus callosum and inferior forebrain white matter microstructure are related to functional outcome from raised intracranial pressure in child traumatic brain injury.

In severe paediatric traumatic brain injury (TBI), a common focus of treatment is raised intracranial pressure (ICP). We have previously reported frontal cerebral vulnerability with executive deficits from raised ICP in paediatric TBI. Now, using diffusion tensor imaging (DTI) in a different population, we have examined fractional anisotropy (FA), and mean, axial and radial diffusivity (MD, AD, RD) in 4 regions of the corpus callosum (CC) and in both inferior frontal regions.

Head circumference and brain and hippocampal volume after severe traumatic brain injury in childhood.

Vulnerability of the hippocampus to traumatic brain injury (TBI) in adults is related to severity of injury and white matter atrophy. The objectives of this study were to determine features of anthropometry and cerebral morphometry late after TBI in childhood and to assess whether hippocampal volume is related to severity of initial ictus and changes in white matter at follow-up. Thirty-three patients underwent magnetic resonance imaging 4.

Initial experience with a physiologic morcellating resectoscope.

A new physiologic morcellating resectoscope allows operative hysteroscopy to be performed with a physiologic distention medium, thus reducing the risk of dilutional hyponatremia and cerebral edema secondary to excessive absorption of nonphysiologic fluid. To study this new technology, we gathered in vitro data with the SL resectoscope with dual-function electrode (FemRx, Sunnyvale, CA). Coupled to a standard monopolar electrosurgery unit and operating in normal saline or Ringer's lactate solution, extirpated uteri showed equivalent depth of tissue necrosis with this new physiologic morcellating resectoscope as with a conventional monopolar resectoscope used in an electrically nonconductive fluid.

Laparoscopic supracervical hysterectomy with a new disposable morcellator.

Laparoscopic supracervical hysterectomy (LSH) can be performed more easily with a powered morcellator for removal of the uterus. Available laparoscopic morcellators are expensive and may be difficult to use, but a new, powered, disposable instrument was developed (Diva; FemRx, Sunnyvale, CA) to morcellate the entire uterus for easy removal through a 15-mm cannula. Twelve consecutive women for whom subtotal hysterectomy was indicated underwent LSH by standard laparoscopic protocol and were monitored postoperatively for a minimum of 1 month.
