Charles Kennedy, one of the first child neurologists in the USA, passed away on October 6, 2015 in Maine at the age of 95 following a brief illness. Born in Buffalo, NY, he attended Nichols School and later Deerfield Academy. He graduated from Princeton University with honors in Chemistry in 1942.

At Princeton, in addition to preparing for medical school, he was also a member of the choir, glee club and the Princeton Nassoons (an all male a cappella group). He went on to receive his MD degree at the University of Rochester while in the Navy V-12 program. Internship was at Yale New Haven Hospital during which time World War II ended. After the war, he remained on active duty in the Navy where he was assigned to the Veterans Administration Psychiatric Hospital in Canandaigua, NY.

Following his 2 years of military service, he went through a pediatrics residency at the Childen’s Hospital of Buffalo. Neurology and Child Neurology training was with Sidney Carter at the Neurological Institute in New York. During this time, Kennedy and Carter published an article on optic neuritis in children and the risk for multiple sclerosis, a paper that spurned future research . Following his fellowship, Charles was appointed Chief of Neurology at the Children’s Hospital of Philadelphia.

Kennedy had a very strong interest in the cerebral blood flow and metabolic requirements of the developing brain. Very early in his career, he developed a close collaboration with Louis Sokoloff, also a physician scientist who never practiced medicine except during internship at Philadelphia General Hospital. As early as 1957, Kennedy et al. (J Clin Invest) used the Kety-Schmidt method (a modification of the Fick Principle) to show for the first time that children require higher cerebral blood flow and oxygen utilization than adults.

In 1967, Kennedy took a sabbatical at the Laboratory of Cerebral Metabolism at the NIH, working with Louis Sokoloff. That sabbatical was a life changing event for Kennedy who decided not to return to his position in Philadelphia but to pursue his research collaboration with Sokoloff at the NIH. He split his time between NIH and Georgetown University School of Medicine, where he was Professor and Chief of Child Neurology. The following years were highly productive and scientifically rewarding. Sokoloff and Kennedy became life-long friends and colleagues; they complemented each other with their skills. A series of experiments investigated the use of various carbon-14 labeled radiotracers and quantitative autoradiography to measure cerebral blood flow.

In 1977, Sokoloff, Reivich , Kennedy and the group published the seminal paper in Journal of Neurochemistry on the 14C-2-deoxyglucose method for the measurement of local cerebral glucose utilization in the rat brain. This method has been widely used in various experimental paradigms in a number of species. Importantly, the method provides the basis for the measurement of glucose metabolism in humans using positron emission tomography (PET), which is now routinely used in the clinical setting.

At Georgetown, Kennedy trained a number of child neurologists who went on to pursue academic careers, including Bennett Lavenstein, Harry Chugani, and Pauline Filippek. He demonstrated great skill clinically. Indeed, there are few who excel both in the clinic and in the laboratory. One of us (HC), as a medical student at Georgetown, was so impressed by his clinical/research activities that I took an elective with Dr. Kennedy at NIH after which I decided to pursue a career in child neurology with a similar area of research. For all those who came in contact with Charles Kennedy he embodied the characteristics of a physician scholar, gentleman, advisor, confidante and role model.

Charles maintained his humor even into his 90’s. He once said: “if you are my age, and you don’t have heart disease or cancer, I guess you just wait for organ failure!” Kennedy is survived by his wife, Eulsum Kennedy, a talented sculptor and painter (of North Korean descent). He joked about her as well by saying: “the reason I remain slim is that my wife has put me on a North Korean diet!” Kennedy is also survived by his sister Florence Davidsen of Iowa City, and 3 children from a previous marriage: Allen Kennedy of NYC, Jacqueline MacMillan of Sommerville, Mass, and Carol Radmer of Valley Park, Mo, and 2 grandchildren. We will miss you Charles.

The 2nd meeting of the Posterior Fossa Society will take place at the Convention Centre Liverpool on Sunday, June 12th 2016.

The Posterior Fossa Society is an international group of researchers and health care professionals (doctors, nurses, psychologists, speech pathologists, linguists, neuroscientists etc.) who are dedicated to research into the causes, features, treatment and prevention of the postoperative Cerebellar Mutism Syndrome (CMS) and Cerebellar Cognitive Affective Syndrome (CCAS) in children and adults. It reaches its goals by systematically gathering and exchanging information on the CMS and CCAS, both online and during international meetings and conferences.

In the first meeting in Reykjavik, Iceland in June 2015, the definition of postoperative Cerebellar Mutism Syndrome was addressed. In the meeting of the Posterior Fossa Society in Liverpool, the focus will be on prevention and treatment of symptoms. The meeting is open to members and non-members of the Society.

In addition to lectures of experts in the field, in the program, one session is reserved for free papers and opportunity for poster presentations.

Abstract submission for free paper session and posters: You are invited to submit abstracts on the topics of prevention of postoperative CMS and treatment of CMS symptoms. All abstracts are to be submitted on line and should be a maximum of 300 words. The abstract should mention:

'Abstract for PFS meeting'
Title of your abstract,
Author and Co-authors
Abstract text (maximum 300 words)
Presentation preference (platform or poster presentation)
Registration fee:
Early registration (1st of January to 25th of March- 2016) £75.00
Standard registration: (25th of March-13th of May 2016) £95.00
Late registration: (13th of May- 15th of June 2016) £125.00
Registration fees include conference material, lunch and refreshments. Participants of the PFS meeting are invited to the SIOP & PFS Dinner on the 11th June evening at 7.30pm – Maritime Museum Albert Dock - £35 per person.

Please note that the program of the Posterior Fossa Society meeting is specifically designed to compliment the 90 minute session on Cerebellar Mutism Syndrome in the main ISPNO meeting for which abstract submission is also welcome.

There have been nearly 60 cases identified in California from 2012 - 2015 of acute flaccid myelitis, a rare syndrome described as polio-like, with most patients being children and young adults, according to a study in the December 22/29 issue of JAMA. The cause of the condition in these cases remains unknown.

With the elimination of wild poliovirus in populations throughout most of the world, the clinical syndrome of acute flaccid paralysis (characterized by weakness or paralysis and reduced muscle tone) due to spinal motor neuron injury has largely disappeared from North America. Despite occasional case reports, the absence of centralized public health surveillance for non-polio acute flaccid paralysis in the United States has precluded accurate incidence estimates. In the fall of 2012, the California Department of Public Health (CDPH) received 3 separate reports of acute flaccid paralysis cases with evidence of spinal motor neuron injury. No such cases had been reported to the program during the preceding 14 years. In response to these unusual case reports, the CDPH implemented enhanced surveillance for similar cases with the goal of characterizing observed cases and identifying possible causes.

Keith Van Haren, M.D., of Stanford University, Palo Alto, Calif., and colleagues summarized reported cases of acute flaccid myelitis, which encompasses a subset of acute flaccid paralysis cases, in patients with radiological or neurophysiological findings suggestive of spinal motor neuron involvement reported to the CDPH with symptom onset between June 2012 and July 2015. Cerebrospinal fluid, serum samples, nasopharyngeal swab specimens, and stool specimens were submitted to the state laboratory for infectious agent testing.

Fifty-nine cases were identified. Median age was 9 years (50 of the cases were younger than 21 years). Symptoms that preceded or were concurrent included respiratory or gastrointestinal illness (n = 54), fever (n = 47), and limb myalgia (n = 41; muscle pain). Among 45 patients with follow-up data, 38 had persistent weakness at a median follow-up of 9 months. Two patients, both immunocompromised adults, died within 60 days of symptom onset.

Enteroviruses were the most frequently detected pathogen in either nasopharynx swab specimens, stool specimens, serum samples (15 of 45 patients tested). No pathogens were isolated from the cerebrospinal fluid. The incidence of reported cases was significantly higher during a national enterovirus D68 outbreak occurring from August 2014 through January 2015 compared with other monitoring periods.

"The etiology of acute flaccid myelitis cases in our series remains undetermined. Although the syndrome described is largely indistinguishable from poliomyelitis on clinical grounds, epidemiological and laboratory studies have effectively excluded poliovirus as an etiology," the authors write.

The researchers note that "ongoing surveillance efforts are required to understand the full and potentially evolving levels of infectious agent-associated morbidity and mortality."

"To our knowledge, the California surveillance program for acute flaccid paralysis is the first to use specific case criteria and report subsequent incidence data for the subset of paralysis cases attributable solely to acute flaccid myelitis and may serve as a guide for similar surveillance efforts in the future."
