      &lt;p&gt;Cyanosis, rapid breathing, poor peripheral perfusion, and petechial rash are red flags for serious childhood infection, a systematic review affirmed.&lt;/p&gt;
&lt;p&gt;Parental concern and physician instinct were also strong warning signs of serious illness in children in developed countries, but only in the primary care setting, Ann Van den Bruel, MD, of Katholieke Universiteit Leuven, Belgium, and colleagues reported online in &lt;em&gt;The Lancet&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The researchers also looked for &quot;rule-out&quot; signs, with a negative likelihood ratio of less than 0.2, but found none, highlighting the difficulties facing clinicians.&lt;/p&gt;
&lt;p&gt;Nor were any of the red flags consistent at presentation in serious cases, suggesting that effective safeguards are needed, they said.&lt;/p&gt;
&lt;p&gt;&quot;There should be more emphasis on parental concern in the diagnostic process,&quot; they wrote. &quot;However, we now need to identify the level of risk at which clinical action should be taken.&quot;&lt;/p&gt;
&lt;p&gt;While the warning signs will be no surprise to most physicians, the poor evidence base should be shocking, Martin Dawes, MBBS, MD, of McGill University in Montreal, wrote in an accompanying editorial.&lt;/p&gt;
&lt;p&gt;Only one of the 30 studies included in the review was conducted in a primary setting, but that&apos;s the most common environment in which sick children are seen, he said.&lt;/p&gt;
&lt;p&gt;&quot;What is clear is that in 2010 we do not know how to effectively recognize or rule out severe disease in ill children and, what is more, we do not even have a cohesive national or even global research strategy to address this problem,&quot; he wrote.&lt;/p&gt;
&lt;p&gt;The World Health Organization has sponsored large scale studies to address these issues in resource-poor countries, Van den Bruel&apos;s group noted, but the range of diseases is different in developed countries, so that evidence doesn&apos;t generalize.&lt;/p&gt;
&lt;p&gt;The investigators reviewed studies of diagnostic accuracy or prediction rules for serious infection (mostly sepsis, bacteremia, meningitis, pneumonia, or urinary tract infection) in otherwise healthy children ages 1 month to 18 years, using features assessable in an ambulatory care setting.&lt;/p&gt;
&lt;p&gt;The studies had generally modest quality and were predominantly conducted in emergency departments.&lt;/p&gt;
&lt;p&gt;Fever of 104&amp;#176;F or more increased the likelihood of serious infection from 0.8% to 5.0% in the lowest prevalence setting.&lt;/p&gt;
&lt;p&gt;In the one primary care study where there was a low prevalence of disease (under 5%), a parent&apos;s concern that her child&apos;s illness was different from prior illnesses had a positive likelihood ratio of 14.40 for serious infection, while the clinician&apos;s instinct that something is wrong had a 23.50 positive likelihood ratio.&lt;/p&gt;
&lt;p&gt;Other predictors of the presence of serious infection and their positive likelihood ratios were: &lt;ul&gt; &lt;li&gt;Turning blue (52.20)&lt;/li&gt; &lt;li&gt;Poor peripheral circulation (4.71 to 38.80 in the low-to-intermediate prevalence setting and 2.39 to 17.70 in the high-prevalence setting)&lt;/li&gt; &lt;li&gt;Rapid breathing (1.26 to 9.78)&lt;/li&gt; &lt;li&gt;Shortness of breath (1.11 to 9.30)&lt;/li&gt; &lt;li&gt;Meningeal irritation (2.57 to 275)&lt;/li&gt; &lt;li&gt;Petechial rash (6.18 to 83.70)&lt;/li&gt; &lt;li&gt;Unconsciousness (19.80 to 155)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Changed crying pattern was a potential red flag in a low prevalence setting with a positive likelihood ratio of 10.50, but actually was associated with reduced probability of serious disease in a high prevalence setting (positive likelihood ratio 0.49 to 0.74).&lt;/p&gt;
&lt;p&gt;Sending all children with a probability of serious infection greater than 5% to the hospital would overwhelm services there, although parents would &quot;probably be unhappy to know that their child was not being referred despite a 1 in 20 risk of serious infection,&quot; the researchers observed.&lt;/p&gt;
&lt;p&gt;The most widely studied decision rule, the Yale Observation Scale, had disappointingly little value in confirming the possibility of serious infection, they noted (positive likelihood ratio range 1.10 to 6.70, negative likelihood ratio range 0.16 to 0.97).&lt;/p&gt;
&lt;p&gt;The best performing clinical decision rule for excluding serious infection was a five-stage system with a negative likelihood ratio of 0.04.&lt;/p&gt;
&lt;p&gt;The researchers noted that these findings largely fit with those identified by WHO for developing countries, with the exception of difficulty feeding. The current review found that wasn&apos;t helpful in developed areas.&lt;/p&gt;
&lt;p&gt;They cautioned that their review was only as strong as the studies included and was particularly limited by the paucity of studies in the initial presentation primary care setting and difficulties of knowing how reproducible the findings were.&lt;/p&gt;

                     title="Parents Often Err in Dosing Kids (CME/CE)"
                     score="0.011"
                     href="http://www.medpagetoday.com/Pediatrics/Parenting/tb/18290?impressionId=1265745482717"
                     
      &lt;p&gt;Adults tasked with giving their children liquid medications often gave them too much, especially when the dosing device was a cup instead of a spoon or oral syringe, researchers said.&lt;/p&gt;
&lt;p&gt;Asked to prepare a 5-mL dose for a child, adult caregivers in a study were almost always within 20% of the target when using a 5-mL syringe, according to a report in the February &lt;em&gt;Archives of Pediatric and Adolescent Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;But about 70% of the 302 parents in the trial put more than 6 mL in cups that were packaged with the medication, H. Shonna Yin, MD, of New York University, in New York City, and colleagues reported.&lt;/p&gt;
&lt;p&gt;Cups with etched markings gave the adults nearly as much trouble, the researchers found, but droppers and dosing spoons were more accurate.&lt;/p&gt;
&lt;p&gt;Yin and colleagues also found that dosing errors were nearly twice as common among caregivers who tested poorly for health literacy (adjusted OR 1.7, 95% CI 1.1 to 2.8).&lt;/p&gt;
&lt;p&gt;Given that many liquid medications come with cups, it may be necessary to reconsider how products intended for young children are packaged, the researchers suggested.&lt;/p&gt;
&lt;p&gt;&quot;Redesign of dosing devices as well as instructions for their use, with a focus on standardization and consistency, has the potential to decrease medication errors and improve safety and efficacy,&quot; Yin and colleagues wrote.&lt;/p&gt;
&lt;p&gt;The researchers recruited adults who brought children to a pediatric clinic in New York&apos;s Bellevue Hospital in late 2008. Participants were given each of six dosing instruments in random order and asked to fill it with one teaspoon (5 mL) of acetaminophen suspension.&lt;/p&gt;
&lt;p&gt;Some 95% of participants were the children&apos;s mothers, with the remaining 5% split between fathers and legal guardians. Most were Hispanic, foreign-born, and poor, and 56% spoke Spanish as their first language. Half were not high school graduates.&lt;/p&gt;
&lt;p&gt;The instruments included the cup packaged with Children&apos;s Tylenol Suspension Liquid, which has printed markings on the side; a cup with etched markings bought from a local drugstore; a 5-mL dropper; a 10-mL dosing spoon; a 5-mL syringe; and a 5-mL syringe with bottle adapter.&lt;/p&gt;
&lt;p&gt;Mean doses actually put into the cups were 6.7 mL (SD 1.7) for those with printed markings and 7.0 (SD 3.2) for those with etched markings.&lt;/p&gt;
&lt;p&gt;Although the mean doses were similar with these devices, fewer parents made errors when using the etched cup. Some 50% of doses measured with it were in the range of 4 to 6 mL, compared with only 30.5% of doses put into the cup with printed markings.&lt;/p&gt;
&lt;p&gt;Small errors (20% to 40% more or less than the target) were also less common with the etched cup: 26.6% of doses, versus 43.7% of doses measured with the printed cup. But the rate of large errors was nearly the same with the two cups, at about 25%.&lt;/p&gt;
&lt;p&gt;With the other instruments, mean doses were close to the target, ranging from 4.6 for the oral syringe with bottle adapter to 5.5 for the spoon.&lt;/p&gt;
&lt;p&gt;From 86% to 94% of doses prepared with these devices were within 20% of the 5-mL target. When errors were made, they were usually small and on the low side of the target, Yin and colleagues found.&lt;/p&gt;
&lt;p&gt;Adjusted odds ratios for making large errors, with the oral syringe as reference, were: &lt;ul&gt; &lt;li&gt;Cup with printed markings: 7.3 (95% CI 4.1 to 13.2)&lt;/li&gt; &lt;li&gt;Cup with etched markings: 6.3 (95% CI 3.5 to 11.2)&lt;/li&gt; &lt;li&gt;Dropper: 0.8 (95% CI 0.5 to 1.5)&lt;/li&gt; &lt;li&gt;Dosing spoon: 0.3 (95% CI 0.1 to 0.9)&lt;/li&gt; &lt;li&gt;Oral syringe with bottle adapter: 0.8 (95% CI 0.5 to 1.5)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;But the spoon was more often associated with dosing errors, both small and large, than the syringe, with an adjusted odds ratio of 1.7 (95% CI 1.1 to 2.7).&lt;/p&gt;
&lt;p&gt;Adjustments included caregivers&apos; age, relationship to child, marital status, language, ethnicity, U.S. birth, socioeconomic status, presence of young child, and presence of child with a chronic medical problem.&lt;/p&gt;
&lt;p&gt;Caregivers were given the Newest Vital Sign test to evaluate their health literacy, which turned out to be a factor in dosing errors, the researchers found.&lt;/p&gt;
&lt;p&gt;Scores of 0 or 1 reflected a high likelihood of limited literacy, 2 or 3 was considered &quot;possible limited literacy,&quot; and 4 to 6 was deemed adequate literacy.&lt;/p&gt;
&lt;p&gt;About 40% of participants had scores of 0 or 1 and 38% scored in the range of 2 to 3.&lt;/p&gt;
&lt;p&gt;Both levels of low health literacy predicted dosing errors, and poor literacy was also significantly associated with increased risk of large errors.&lt;/p&gt;
&lt;p&gt;Adjusted odds ratios for any dosing error and large errors associated with poor literacy were 1.7 (&lt;em&gt;P&lt;/em&gt;=0.02) and 2.3 (&lt;em&gt;P&lt;/em&gt;=0.01), respectively.&lt;/p&gt;
&lt;p&gt;Possible limited literacy predicted any dosing error and large errors with adjusted odds ratios of 1.6 (&lt;em&gt;P&lt;/em&gt;=0.04) and 1.9 (&lt;em&gt;P&lt;/em&gt;=0.07), respectively.&lt;/p&gt;
&lt;p&gt;These findings on health literacy and medication errors have important implications for the design of dosing instruments, Yin and colleagues indicated.&lt;/p&gt;
&lt;p&gt;&quot;Provision of instruments designed to place fewer literacy demands on families is one strategy to decrease dosing errors,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;Limitations to the study included its setting in a clinic, which may not reflect parents&apos; performance at home; the largely Hispanic immigrant sample with low socioeconomic status; and the use of a written test to assess health literacy, which does not measure verbal comprehension and other skills that may contribute to health literacy.&lt;/p&gt;

Yin received partial support from the Pfizer Fellowship in Health Literacy/Clear Health Communication.&lt;/p&gt;&lt;p&gt;No potential conflicts of interest were reported.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

                     score="0.009"
                     href="http://www.medpagetoday.com/ProductAlert/DevicesandVaccines/tb/18229?impressionId=1265745482717"
                     
      &lt;p&gt;WASHINGTON  --  The FDA has updated labels of the HIV drug didanosine (Videx and Videx EC) to include warnings for potentially serious liver damage.&lt;/p&gt;
&lt;p&gt;Although these cases are rare, the drug may cause noncirrhotic hypertension in patients, a potentially fatal complication which the FDA discovered through 42 postmarket, adverse event reports.&lt;/p&gt;
&lt;p&gt;Of those patients, three required liver transplant and four died. Two deaths were caused by esophageal hemorrhage, while two more were caused by progressive liver failure.&lt;/p&gt;
&lt;p&gt;One patient suffered multiorgan failure, cerebral hemorrhage, sepsis, and lactic acidosis.&lt;/p&gt;
&lt;p&gt;The FDA said in a statement that it chose not to recall the drug because it believes its benefits outweigh potential risks, but advised that treatment decisions be made on an individual basis between healthcare professionals and patients.&lt;/p&gt;
&lt;p&gt;The agency added that causal association is difficult to determine in postmarket reports, but that alternative causes of the hypertension were ruled out in well-documented cases.&lt;/p&gt;
&lt;p&gt;Healthcare professionals who determine didanosine is effective in treating a patient should monitor that patient for the development of portal hypertension and esophageal varices, the agency said.&lt;/p&gt;
&lt;p&gt;Didanosine is used in combination with other HIV medications to help maintain CD4 cells in patients.&lt;/p&gt;
&lt;p&gt;The drug already has a black box warning for lactic acidosis and hepatomegaly with steatosis.&lt;/p&gt;
&lt;p&gt;Like the antiretroviral agents hydroxyurea and ribavirin, didanosine has been associated with the development of liver toxicity.&lt;/p&gt;

                     score="0.009"
                     href="http://www.medpagetoday.com/PublicHealthPolicy/EnvironmentalHealth/tb/18228?impressionId=1265745482717"
                     
      &lt;p&gt;WASHINGTON  --  U.S. Marshals have seized 77 unapproved ozone generators, valued at almost $76,000 from a California device manufacturer, the FDA announced.&lt;/p&gt;
&lt;p&gt;The devices were advertised as treatments for various conditions, including cancer, AIDS, hepatitis, herpes, and other diseases, but lacked approval or efficacy data to support the claims made on their behalf, an FDA release said.&lt;/p&gt;
&lt;p&gt;The raid came after the company, Applied Ozone Systems (AOS) of Auburn, Calif., failed to respond to a voluntary recall request last December, the agency said.&lt;/p&gt;
&lt;p&gt;The FDA raised concerns that patients using AOS-IM and AOS-IMD devices will consider it an appropriate treatment for an affliction and delay or stop FDA-approved and proven medical treatments. Patients using the devices may risk infection from contamination of the applicator or catheter, the release said.&lt;/p&gt;
&lt;p&gt;The FDA recommended that healthcare professionals and consumers cease use of the devices.&lt;/p&gt;
&lt;p&gt;The agency said it obtained an inspection warrant for the company&apos;s manufacturing facilities after the owner refused to admit FDA inspectors. It said the inspection revealed several breaches of the FDA&apos;s good manufacturing practice requirements for medical devices, which had never been approved in the first place.&lt;/p&gt;
&lt;p&gt;Ozone is an unstable allotrope of oxygen with three atoms, instead of the normal two. Ozone generators produce ozone from oxygen and have consumer and industrial applications, but ozone itself is harmful to the respiratory system, even at relatively low concentrations.&lt;/p&gt;
&lt;p&gt;Instructions with the Applied Ozone Systems devices suggest blowing ozoned air into the rectal and vaginal areas.&lt;/p&gt;
&lt;p&gt;Friday&apos;s seizure was part of a joint effort of the FDA and the California Department of Public Health to remove or prevent unapproved or unsafe medical devices from entering the market.&lt;/p&gt;
&lt;p&gt;A statement on the company&apos;s Web site said the two ozone generator models, which sold for $750 and $1,200 respectively, were no longer available by order of the FDA and California authorities.&lt;/p&gt;

                     title="Rotavirus Vaccine Effective in Third World Nations (CME/CE)"
                     score="0.006"
                     href="http://www.medpagetoday.com/Pediatrics/Vaccines/tb/18174?impressionId=1265745482717"
                     
      &lt;p&gt;Vaccination against rotavirus appears to be highly effective in reducing death and serious gastrointestinal disease among young children in developing countries, according to two&lt;strong&gt; &lt;/strong&gt;publications in the Jan. 28 &lt;em&gt;New England Journal of Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;In Malawi and South Africa, a vaccination program significantly reduced infantile gastroenteritis associated with the pathogen, researchers said.&lt;/p&gt;
&lt;p&gt;In a companion paper, investigators reported that a rotavirus vaccination program in Mexico appears to have been the cause of a marked reduction in deaths from diarrhea among young children.&lt;/p&gt;
&lt;p&gt;Taken together, the two studies suggest that physicians have &quot;another powerful weapon&quot; to help prevent death from diarrhea among young children, according to Mathuram Santosham, MD, of the Johns Hopkins Bloomberg School of Public Health, who was not involved in the research.&lt;/p&gt;
&lt;p&gt;&quot;It is time to act to combat the 1.8 million unnecessary deaths from diarrhea that continue to occur each year,&quot; Santosham wrote in an accompanying editorial.&lt;/p&gt;
&lt;p&gt;Two oral, live attenuated vaccines against rotavirus have been shown to prevent the associated gastroenteritis  --  GlaxoSmithKline&apos;s Rotarix and Merck&apos;s RotaTeq, according to Nigel Cunliffe, MBChB, PhD, of the University of Liverpool in England, and colleagues.&lt;/p&gt;
&lt;p&gt;But trials of those drugs mainly occurred in more developed countries, the researchers noted, so the World Health Organization  --  fearing they might not work as well among the very poor  --  suggested additional trials in the Third World.&lt;/p&gt;
&lt;p&gt;To fill the knowledge gap, Cunliffe and colleagues conducted a randomized, placebo-controlled trial in Malawi and South Africa, enrolling 4,939 healthy infants.&lt;/p&gt;
&lt;p&gt;They were assigned to get either three doses of placebo (at six, 10, and 14 weeks of age), two doses of the Rotarix vaccine and one of placebo to maintain blinding, or three doses of the vaccine.&lt;/p&gt;
&lt;p&gt;The researchers found: &lt;ul&gt; &lt;li&gt;Severe gastroenteritis caused by rotavirus occurred in 4.9% of the placebo group and in 1.9% of the pooled vaccine group, yielding a vaccine efficacy of 61.2%, which was significant at &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001. &lt;/li&gt; &lt;li&gt;Vaccine efficacy was lower in Malawi than in South Africa  --  49.4% versus 76.9%. But the vaccine prevented more cases of severe rotavirus gastroenteritis in Malawi  --  6.7 cases prevented per 100 infants vaccinated yearly versus 4.2.&lt;/li&gt; &lt;li&gt;Efficacy against all-cause severe gastroenteritis was 30.2%.&lt;/li&gt; &lt;li&gt;At least one serious adverse event was reported in 9.7% of the vaccinated infants and 11.5% of the placebo group, but only three were judged to be related to the vaccine.&lt;/li&gt; &lt;li&gt;There was a single case of intussusception -- a 6-month-old child in the three-dose vaccine group, who recovered after bowel resection.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The findings have led WHO to recommend that rotavirus vaccination be included in all national immunization programs, Cunliffe and colleagues noted.&lt;/p&gt;
&lt;p&gt;Mexico phased in rotavirus vaccination over slightly more than a year, from February 2006 through May 2007, according to Manish Patel, MD, of the CDC, and colleagues.&lt;/p&gt;
&lt;p&gt;To estimate the effect of the program, Patel and colleagues compared annual deaths from diarrhea before and after the immunization program began.&lt;/p&gt;
&lt;p&gt;Over the four years before the program started, the median annual number of diarrhea-related deaths among children younger than five was 1,793, the researchers found, for a mortality rate of 18.1 deaths per 100,000.&lt;/p&gt;
&lt;p&gt;In 2008, by contrast, there were 1,118 deaths, a reduction of 765, which yielded a mortality rate of 11.8 per 100,000 children, they reported in the journal.&lt;/p&gt;
&lt;p&gt;The rate reduction of 35% was significant at &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001, Patel and colleagues said.&lt;/p&gt;
&lt;p&gt;The findings come with some caveats, the researchers said. Among them: &lt;ul&gt; &lt;li&gt;It was not possible to pin down the reduction in deaths attributable to vaccination because precise vaccine coverage information is lacking. &lt;/li&gt; &lt;li&gt;Other changes, such as hygiene improvements, might also have affected the trend.&lt;/li&gt; &lt;li&gt;Because of difficulty obtaining fecal specimens, it wasn&apos;t possible to study trends in rotavirus deaths specifically.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;While the studies suggests that rotavirus vaccination would prevent much disease and many deaths, there are obstacles to introducing the vaccine to poorer countries, Santosham noted in the editorial.&lt;/p&gt;
&lt;p&gt;A key obstacle, he said, is that the vaccine requires more refrigeration  --  so-called &quot;cold-chain&quot; storage  --  than typical childhood vaccines.&lt;/p&gt;
&lt;p&gt;Also problematic, he said, is the current recommendation that the vaccines be given early in life to avoid age-dependent occurrence of intussusception, which led to an earlier vaccine being taken off the market.&lt;/p&gt;
&lt;p&gt;In many of the poorest countries, on-time vaccination is rare, which may impede the use of a rotavirus vaccine unless the time window for administration can be opened wider, he said.&lt;/p&gt;

Cunliffe reported financial links with Sanofi Pasteur and GlaxoSmithKline.&lt;/p&gt;&lt;p&gt;For the Mexican study, the researchers did not report any external support or any conflicts.&lt;/p&gt;&lt;p&gt;Santosham reported financial links with GlaxoSmithKline and Merck, both of which make rotavirus vaccines.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;
