Alcyone Lifesciences wins FDA nod for Alivio hydrocephalus shunt flusher
Alcyone Lifesciences said yesterday it won FDA 510(k) clearance for its Alivio ventricular catheter and flusher system designed for treating hydrocephalus. The newly cleared Alivio device is designed for the non-invasive retrograde flushing of the ventricular catheter to unblock occluded inlet holes or open a relief membrane to restore or increase cerebrospinal fluid flow in non-flowing shunts, the Lowell, Mass.-based company said. “For the first time in over half a century there has been a game changing improvement in the field of hydrocephalus treatment.  Ventricular shunting can help save lives and improve th...

What Clinical Signs Can Be Associated With Benign External Hydrocephalus?
Discussion Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles and/or subarachnoid spaces. External hydrocephalus is a communicating hydrocephalus often defined as the patient having a rapidly enlarging head circumference (HC) and enlargement of the subarachnoid spaces especially over the frontal lobes with normal or moderately enlarged ventricles. Benign external hydrocephalus (BEH) is a self-limited external hydrocephalus that occurs during infancy and resolves spontaneously in childhood, usually by age 2 years, that is felt to not cause significant problems. It was first described by...

FDA labels Medtronic StrataMR recall as Class I
The FDA today released updated information on Medtronic‘s (NYSE:MDT) recall of StrataMR adjustable valves and shunts over issues with fluid buildup, labeling it as Class I. The StrataMR adjustable valves and shunts are intended for the management of hydrocephalus by providing cerebrospinal fluid flow from the ventricles of the brain into the right atrium of the heart or peritoneal cavity. The recall relates to issues with flow resistance that could lead to under-drainage of cerebrospinal fluid, arising when the valve mechanism is adjusted to a position which causes higher-than-intended flow r...

Evaluation of the use of human umbilical cord for in-utero spina bifida repair
Spina Bifida is a birth defect where there is an incomplete closure of the backbone and the coverings around the spinal cord. It affects more than 4,000 children born each year in the United States and is associated with hydrocephalus (fluid in the brain), developmental delay, lifelong disability and death. Spina Bifida is also associated with a need for shunt placement. In-utero surgery has been shown to reduce the need for shunting of hydrocephalus and to improve a child's ability to walk.

Staying ontop of hydrocephalus shunt failure with ShuntCheck
Antonio Venus-Reeve, 14, had his first shunt surgery for hydrocephalus when he was 2½ months old. Born at 25 weeks’ gestation, weighing less than two pounds, he had a serious brain bleed seven days later. As Antonio’s head began to swell with excess fluid, neurologists at Boston Children’s Hospital told his mother, Joanne Venus-Williams, that Antonio probably would not be able to walk, talk or develop major motor skills. “Neurosurgery got involved and the team did daily spinal taps to draw out the fluid in his brain,” says Venus-Williams. “They were hoping he wouldn’t need ...

Effects of prenatal myelomeningocele closure on the need for a CSF shunt
(Journal of Neurosurgery Publishing Group) Investigators reaffirm the initial MOMS finding that prenatal repair of a myelomeningocele results in less need for a shunt at 12 months and introduce the new finding that prenatal repair reduces the need for shunt revision in those infants who do require shunt placement. The researchers also found that patients with extensive hydrocephalus at the time of the prenatal evaluation did not show improved outcomes following prenatal surgery. (Source: EurekAlert! - Biology)

Preemie Jace Perkins rocks ’n rolls through 137 days in the NICU
Melyssa Perkins was 25 weeks into a healthy pregnancy with her first child when she began to have abdominal pain. She called her local nurse who said she was probably dehydrated, but when water didn’t help and the pain increased, Melyssa and her husband Jamie rushed to nearby Beverly Hospital, where they discovered that she was fully dilated. “I don’t think I said one word at that point. I was in complete shock,” recalls Melyssa. Two hours after the couple arrived at the hospital, their son Jace was born at 1lb. 12 oz. Beverly Hospital stabilized Jace and arranged for immediate transport to the Neon...

A second chance for a baby with a life-threatening brain cyst
Photo courtesy of Jennifer Hammond Other than being born a little early—at 37 weeks—everything started out fine for Liam Hammond. “He was a healthy baby, it was a healthy birth, and he was progressing and meeting his milestones,” says his mother Jennifer. But at his 4-month-old check-up, “Something about his head looked different to me.” Liam’s head circumference was normal, though, and he was in the same head-growth percentile as at his last visit. The pediatrician suggested Jennifer keep watching it. Two weeks later, the family left for a seaside Memorial Day weekend vacation. &l...

Global connections: Khalid’s story
When faced with a sick child, every parent in the world wants the same thing—the best care possible. Often, all it takes is a quick visit with the local health care provider. Occasionally, it means a trip to the local hospital or short stay at an academic medical center. In rare cases, obtaining the best care requires an extraordinary effort. A mother finds herself researching the world’s best pediatric neurosurgeons. An uncle turns to YouTube to learn more about brain tumors. Physicians on opposite corners of the globe find ways to communicate and collaborate. And a family boards an air ambulance, embarking on...

Generation of a Central Nervous System Catheter-Associated Infection in Mice with Staphylococcus epidermidis
Animal models are valuable tools for investigating the in vivo pathogenesis of Staphylococcus epidermidis infections. Here, we present the procedure for generating a central nervous system catheter-associated infection in a mouse, to model the central nervous system shunt infections that frequently complicate the treatment of hydrocephalus in humans. This model uses stereotactic guidance to place silicone catheters, pre-coated with S. epidermidis, into the lateral ventricles of mice. This results in a catheter-associated infection in the brain, with concomitant illness and inflammation. This animal model is a valuable tool...
