                     score="-0.003"
                     href="http://www.medpagetoday.com/Surgery/Otolaryngology/tb/18018?impressionId=1265783546327"
                     
      Although children who are deaf may be able to hear when fitted with cochlear implants in both ears, they have a more difficult time controlling their voices than kids with normal hearing, a single-center study showed.&lt;br&gt;
&lt;br&gt;Children with bilateral implants had deficits in controlling both the pitch and loudness of their voices when making a sustained &quot;ahh&quot; sound (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for both), according to Karen Gordon, PhD, of the Hospital for Sick Children in Toronto, and colleagues.&lt;br&gt;
&lt;br&gt;Pitch control, however, improved significantly the longer the implants were used (&lt;em&gt;P&lt;/em&gt;=0.03), the researchers reported in the January issue of &lt;em&gt;Archives of Otolaryngology  --  Head &amp;amp; Neck Surgery.&lt;/em&gt;&lt;br&gt;
&lt;br&gt;&quot;The more experience one has with hearing, the better able to produce voice they have,&quot; Gordon said in an interview.&lt;br&gt;
&lt;br&gt;The number of children who receive cochlear implants for deafness has been increasing steadily over the past two decades, and it is now common, she said.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;The implants directly stimulate the auditory nerve to compensate for a nonfunctioning cochlea, regardless of the reason for the deafness.&lt;/p&gt;
&lt;p&gt;At the Hospital for Sick Children, a multidisciplinary team  --  including an audiologist, otolaryngologist, social worker, speech language pathologist, and auditory verbal therapist  --  assesses each child&apos;s suitability for the implants.&lt;/p&gt;
&lt;p&gt;&quot;We really look at the child, their candidacy from a hearing point of view, their expectations for what the implant can do for them, whether they&apos;re up for the surgery, and whether they&apos;re up for the therapy that&apos;s involved afterward,&quot; Gordon said.&lt;/p&gt;
&lt;p&gt;Although children with cochlear implants are able to hear, it&apos;s unclear exactly what their perception of sound is, she said. All must go through therapy lasting about two years to be able to interpret what they&apos;re hearing.&lt;/p&gt;
&lt;p&gt;However, the voicing of children with the implants compared with that of kids with normal hearing has not been extensively studied.&lt;/p&gt;
&lt;p&gt;So Gordon and her colleagues evaluated how 27 children with bilateral implants  --  ages 3 to 15  --  were able to control their voices, finding poorer control of long-term frequency perturbation (pitch) and long-term amplitude perturbation (loudness) compared with those with normal hearing.&lt;/p&gt;
&lt;p&gt;&quot;Despite the incredible opportunities that cochlear implants provide for auditory and linguistic development, abnormalities in acoustic voice outcomes persist,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;However, through a four-month follow-up, pitch control  --  but not loudness control  --  improved significantly with increased implant use.&lt;/p&gt;
&lt;p&gt;&quot;This result underlines the importance of early recognition and treatment of children with hearing loss to provide auditory experience as soon as possible,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;However, the use of cochlear implants is not free of complications, according to another study in the same issue of the journal by Natalie Loundon, MD, of the H&amp;#244;pital d&apos;Enfants Armand-Trousseau in Paris, and colleagues.&lt;/p&gt;
&lt;p&gt;Among 434 children younger than 16 who received the devices, 9.9% had complications, nearly two-thirds of which occurred more than eight days after implantation (mean 2.2 years).&lt;/p&gt;
&lt;p&gt;Major complications included severe cutaneous infections or hematoma, magnet displacement, meningitis, cholesteatoma, cerebrospinal fluid leak, and electrode misplacement.&lt;/p&gt;
&lt;p&gt;Minor complications included vertigo, soft-tissue infection, persistent otitis media, and facial nerve palsy.&lt;/p&gt;
&lt;p&gt;A large minority of those with complications (30.2%) required reimplantation.&lt;/p&gt;
&lt;p&gt;Trauma to the mastoid area and inner ear malformations were risk factors for delayed major complications and early minor complications, respectively (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for both).&lt;/p&gt;
&lt;p&gt;Age at implantation was not associated with complication risk.&lt;/p&gt;
&lt;p&gt;&quot;The finding of complications several years after surgery highlights the need for long-term medical follow-up in this population and the importance of repeatedly providing information to the patients and their family,&quot; Loundon and colleagues wrote.&lt;/p&gt;

                     score="-0.003"

      Whether a clinician calls a mild traumatic brain injury a concussion or not appears to influence how serious the injury is considered to be, researchers found.&lt;br&gt;
&lt;br&gt;Among children admitted for a traumatic brain injury, those who were told they had a concussion were discharged significantly earlier (OR 1.49, 95% CI 1.15 to 1.94) and returned to school sooner (OR 2.42, 95% CI 1.56 to 3.73) than those who were not given the label, Carol DeMatteo, MSc, of McMaster University in Hamilton, Ontario, and colleagues reported in the February issue of &lt;em&gt;Pediatrics&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The trends remained significant even after adjusting for the severity of the head injury and the presence of other injuries.&lt;/p&gt;
&lt;p&gt;&quot;We suggest that the [concussion] label itself conveys a message and also directs outcomes,&quot; the researchers wrote. &quot;If we want to encourage full reporting with subsequent adequate management and convalescence, perhaps we should use the term &apos;mild traumatic brain injury.&apos;&quot;


 &lt;p&gt;Disagreeing was Kenneth Perrine, PhD, a neuropsychologist at Hackensack University Medical Center in New Jersey.
    &lt;p&gt;&quot;Granted, concussion is by definition a mild brain injury, but it&apos;s so transient that I think it would be a disservice both to the public and for research to continue to confuse mild traumatic brain injury with concussion,&quot; said Perrine, who was not involved in the study.
    &lt;p&gt;He said a true concussion is characterized by feeling like one is in a fog, fatigue, sensitivity to light and sound, headache, blurred vision or other visual disturbances, and feeling off balance.
    &lt;p&gt;A mild traumatic brain injury, on the other hand, has longer-lasting effects and is not usually accompanied by concussion symptoms. Retrograde amnesia, post-traumatic amnesia, and more severe memory loss would occur, he said.
    &lt;p&gt;&quot;They are two distinct entities both from what we call it and from a prognostic standpoint,&quot; said Perrine, who is also consulting neuropsychologist for the New York Jets.
    &lt;p&gt;But, although the term concussion is used widely in clinical records and has garnered much attention in recent years because of head injuries to athletes at all levels of sports, an accepted definition does not exist, according to DeMatteo and her colleagues.&lt;/p&gt;


&lt;p&gt;&quot;Clinicians may use the concussion label because it is less alarming to parents than the term &quot;mild brain injury,&quot; with the intent of implying that the injury is transient with no signi&amp;#64257;cant long-term health consequences,&quot; they said.&lt;/p&gt;

&lt;p&gt;Commenting on the study, Wendy Wright, MD, a neurologist at Emory University in Atlanta, said in an e-mail, &quot;This study puts a spotlight on the issue that concussion is not always taken as seriously as it should be, partly because concussion encompasses a spectrum of disease.&quot;&lt;/p&gt;
&lt;p&gt;She said parents, coaches, teammates, and the individual with the concussion may not believe the injury is serious because symptoms are transient.&lt;/p&gt;
&lt;p&gt;That perception appears to be held by both clinicians and parents alike. DeMatteo and colleagues noted in the journal that during recruitment of the current study, both groups were heard saying, &quot;He doesn&apos;t have a head injury, he has a concussion.&quot;&lt;/p&gt;
&lt;p&gt;However, Wright said, &quot;it must be noted that concussion means brain injury.&quot;&lt;/p&gt;


&lt;p&gt;To explore how the term is used clinically, DeMatteo and colleagues analyzed the records of 434 children admitted to McMaster Children&apos;s Hospital with a diagnosis of acquired brain injury.&lt;/p&gt;
&lt;p&gt;Of those determined to have a traumatic brain injury, 72.7% had a mild injury according to the Glasgow Coma Scale. Nearly one-third (32.4%) were said to have a concussion.&lt;/p&gt;
&lt;p&gt;The concussion label was more likely to be given to children with a mild injury (&lt;em&gt;P&lt;/em&gt;=0.03), but the association was weak, according to the researchers, and nearly one-quarter (24%) of children with moderate or severe scores were also said to have a concussion.&lt;/p&gt;
&lt;p&gt;&quot;This leads one to question the use of the term as being reflective of mild injury and again supports the existence of confusion about what a concussion really is and how the term should best be used in the care of children,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;Our findings, both in the return-to-school data and the phenomenon we experienced during recruitment, suggest that if a child is given a diagnosis of concussion, then the family is less likely to consider it as a brain injury,&quot; the researchers said.&lt;/p&gt;
&lt;p&gt;They acknowledged some limitations of the study, including the fact that data from medical charts may have had missing information and a lack of control over the validity of measurements and that their use of only a single center might influence the results.&lt;/p&gt;
&lt;p&gt;Further, they wrote, some measures, such as CT frequency, might be inflated because only children who were admitted to the hospital were included in the study. &lt;ul&gt; &lt;/ul&gt;&lt;/p&gt;

The &lt;em&gt;CanChild&lt;/em&gt;&lt;em&gt;&lt;/em&gt; Center for Childhood Disability Research is supported by the Ontario Ministry of Health and Long-Term Care.&lt;/p&gt;&lt;p&gt;The authors reported that they had no relevant financial disclosures to make.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

                     title="Doctors Overlook Signs of Child Abuse (CME/CE)"
                     score="-0.005"
                     href="http://www.medpagetoday.com/Pediatrics/DomesticViolence/tb/17213?impressionId=1265783546327"
                     
      &lt;p&gt;Physicians often misdiagnose bone fractures caused by child abuse as accidental breaks, particularly if the child is male and the doctor is not a pediatrician, a new study found.&lt;/p&gt;
&lt;p&gt;Of children who suffered fractures from abuse, about 20% had at least one previous medical visit during which a doctor missed signs of the problem (95% CI 15.8 to 26.0), according to a report published online Nov. 30 in &lt;em&gt;Pediatrics&lt;/em&gt;. It took a median of eight days after the initial visit before doctors correctly assessed abuse during a subsequent examination.&lt;/p&gt;
&lt;p&gt;Doctors were most likely to misdiagnose abusive fractures if the patients were boys, had breaks in the limbs, or were seen in a primary care setting or general emergency room, as opposed to a pediatric emergency department.&lt;/p&gt;
&lt;p&gt;&quot;This study is the first to report the frequency of delayed recognition of abusive fractures in children,&quot; Kathy Boutis, MD, MSc, of the Hospital for Sick Children, University of Toronto, and colleagues wrote. &quot;One-fifth of children with abusive fractures were missed at initial physician visits, which is comparable to that reported for other types of abuse; however, we do not know how many cases of abusive fractures are never detected.&quot;&lt;/p&gt;
&lt;p&gt;While fractures are common signs of child abuse and repeat injuries occur in 35% of child abuse cases, previous research suggested that doctors have difficulty distinguishing breaks caused by accidents from those resulting from abuse  --  and thus miss a chance to prevent further abuse.&lt;/p&gt;
&lt;p&gt;However, the frequency at which cases of abuse are overlooked was unknown.&lt;/p&gt;
&lt;p&gt;The authors assessed 258 cases of children younger than 3 years treated for abusive fractures at Toronto Hospital for Sick Children between January 1993 and December 2007. The children had seen physicians previously for treatment of fractures. Of the children, 54 had a least one previous visit with a physician at which abuse was missed, the study found.&lt;/p&gt;
&lt;p&gt;Abuse-related fractures were nearly twice as likely to be missed in boys as in girls. &quot;Although the reason for this is unclear, injuries in general occur more often in boys, which may bias a clinician in assuming that the cause of a fracture is accidental,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;Of the 145 children with breaks to an extremity, 28% (95% CI 20.8 to 35.8) were cases of abuse that were overlooked. About a third of the cases of abuse that were missed on the initial visit were the result of physicians not diagnosing fractures from radiographs.&lt;/p&gt;
&lt;p&gt;&quot;This study suggests that front-line physicians should strongly consider consulting a radiologist when the presence of a fracture may lead to increased suspicion of abuse,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;They also suggested that physicians carefully check for other risk factors of abuse in children with fractures and that they err on the side of performing skeletal surveys for children who are at higher risk.&lt;/p&gt;
&lt;p&gt;They cautioned that the study was retrospective, and that some cases of abuse may have been overlooked by the researchers because they were never referred to the child protection team at the hospital.&lt;/p&gt;
&lt;p&gt;On the other hand, complex cases may not have been referred to the child abuse team, which may have elevated the estimate of the percentage of abuse cases that are overlooked on a child&apos;s initial physician visit for a fracture.&lt;/p&gt;
&lt;p&gt;&quot;However,&quot; the authors wrote, &quot;child abuse is under-recognized, and there is also the possibility that we are underestimating the proportion of cases missed.&quot;&lt;/p&gt;
