Parents, please take note. The frequency of brain tumours has been underestimated in children with the common genetic syndrome — neurofibromatosis type 1 (NF1), a new study has found.

According to the researchers, this disorder is characterised by birthmarks on the skin and benign nerve tumours that develop in or on the skin. Brain tumours are also known to occur in children and adults with NF1.

They estimated that only 15-20 per cent of kids with NF1 develop brain tumours. But the study, published in the journal Neurology: Clinical Practice, found that the frequency of brain tumours in this population was more than three times higher.

“I’m not delivering the message anymore that brain tumours are rare in NF1. This study has changed how I decide which children need more surveillance and when to let the neuro-oncologists know that we may have a problem,” said senior author David H. Gutmann from the Washington University School of Medicine.

Brain Magnetic Resonance Imaging (MRI) scans of children with NF1 characteristically show bright spots that are absent in the scans of unaffected children. Unlike tumours, they are generally thought to disappear in teenage years, the researchers said.

Since brain tumours can be confused with harmless bright spots, it has never been clear whether finding these abnormalities via MRI should be a cause for concern, they added.

For the study, the team developed a set of criteria to distinguish tumours from other bright spots. The researchers then analysed scans from 68 NF1 patients and 46 children without NF1 for comparison.

All but four (94 per cent) of the children with NF1 had bright spots, and none of the children without NF1 did. Further, in 57 per cent of the children with bright spots, at least one of the spots was deemed likely to be a tumour, the research team found.

Applying the new criteria to MRI scans will help physicians identify probable tumours, but that does not mean that all children with NF1 should be scanned regularly, the researchers cautioned. (IANS)

Lack of Proper Sanitation Affects 620 Million Children Around The World: Report

Despite the improvements, more than a third of the girls in South Asia miss school for one to three days a month during their period.

A lack of proper school toilets threatens the health, education and safety of at least 620 million children around the world, the charity WaterAid said in a new study published Friday.

Children at 1 in 3 schools lack access to proper toilets, putting them at risk of diarrhea and other infections and forcing some to miss lessons altogether, according to the study, based on data from 101 countries.

Guinea-Bissau in West Africa has the worst school toilets while Ethiopian children fare worst at home, with 93 percent of homes lacking a decent toilet according to the report, released ahead of World Toilet Day on Monday.

“The message here is that water and sanitation affect everything,” WaterAid spokeswoman Anna France-Williams told the Thomson Reuters Foundation. “If there’s no toilet in schools, children will miss lessons and it will have an impact on their growing up.”

Diarrhea, infection risk

A lack of proper sanitation puts millions of children around the world in danger of diarrhea, which kills 289,000 children younger than 5 a year, WaterAid said.

But some regions have started to clean up their act, notably South Asia, where access to toilets in schools has improved.

More than half the schools in Bangladesh now have access to decent toilets, while students in 73 percent of schools in India and 76 percent of those in Bhutan can access basic sanitation.

Akramul Islam, director of water, sanitation and hygiene at the Bangladeshi charity BRAC, said the country’s once-high levels of open defecation — using open ground rather than toilets — were now less than 1 percent.

“Today, schools have separate toilets for girls and boys and the issue of menstrual hygiene is also being addressed,” he said. “This has happened because of initiatives taken by both the government, the NGOs and other stakeholders.”

Improvement needed

Despite the improvements, more than a third of the girls in South Asia miss school for one to three days a month during their period, WaterAid said, urging greater investment in basic sanitation.

“If we are serious about all children and young people, wherever they are, whatever their gender, physical ability or community background, having their right to clean water and sanitation, we must take decisive and inclusive action now,” said Chief Executive Tim Wainwright. (VOA)
