Huge population at fluorosis risk

High fluoride levels in water in 14,132 habitations in 19 States
With drinking water in 14,132 habitations in 19 States still containing fluoride above the permissible levels, the Union Health and Family Welfare Ministry fears that a huge population is at risk of serious health conditions such as skeletal fluorosis.
The Ministry has now urged the Drinking Water and Sanitation Ministry to ensure the supply of safe drinking water in these habitations.
Data collated by the latter say Rajasthan has the highest number of such habitations (7,670), affecting 48,84,613 people. Telangana has 1,174 such districts with 19,22,783 affected people. Karnataka has 1,122 such districts and Madhya Pradesh 1,055. Assam, Andhra Pradesh, Bihar, Chattisgarh, Maharashtra, Odisha, West Bengal and Uttar Pradesh too face the problem.
The World Health Organization guideline value for fluoride is 1.5 mg per litre, with a target of between 0.8 and 1.2 mg per litre to maximise benefits and minimise harmful effects. Fluoride levels in the body depend on climate and intake of the chemical from drinking water and other sources, the WHO says.
Fluoride contamination affects the teeth and bones and long-term excessive exposure causes abdominal pain, excessive saliva, nausea, vomiting, seizures and muscle spasms.
The WHO says fluroide levels above 1.5 mg per litre causes pitting of tooth enamel and deposits in bones. Levels above 10 mg per litre cause the crippling skeletal fluorosis.
The government has started the National Programme for Prevention and Control of Fluorosis in 2008-09. In 2013-14, the programme was brought under the National Rural Health Mission, which has so far covered 111 districts.
The programme includes surveillance of fluorosis in the community, training and manpower support, establishment of diagnostic facilities, treatment and health education. The Indian Council of Medical Research has formed a task force on fluorosis to address issues related to prevention and control.

Why America's Ebola patients survive

What does your tongue say about your health? From allergies to syphilis, the signs of illness hidden in your mouth
- Scientists in India have developed a new test to spot 14 conditions
- Aimed at those people in remote areas without regular access to doctors
- Black tongue is a sign of over use of antibiotics and fungal overgrowth in HIV patients, while long furrows in the surface are indicative of syphilis
- Test uses symptoms combined with an image of the patient's tongue
- Can offer a likely diagnosis and indicate if someone should see a doctor
Indian scientists have developed a new test to detect what your tongue indicates about a person's health. It can spot 14 different conditions
For those feeling under the weather, the old adage of 'stick your tongue out', may betray the signs of the illness by which they are afflicted.
The tongue can signal signs of a cough, fever, jaundice, headache or bowel habits, and helps doctors make their diagnosis.
A healthy tongue should be pink, clean and covered in papillae, which contain taste buds.
But inflamed, red, black or white tongues could be a sign of other conditions such as thrush, while a swollen tongue can be a sign of an allergic reaction.
Meanwhile a black, discoloured tongue is indicative of extended antibiotic use, or a fungal overgrowth in HIV patients, say Indian scientists.
And long furrows on the surface are a sign of the sexually transmitted infection, syphilis.
Ulcers should ring alarm bells, warning of Crohn's disease or ulcerative colitis.
And a 'beefy and smooth' tongue might reveal vitamin B12, iron or folate deficiency, and anemia.
Moving on to more serious conditions, sores or lumps on the tongue - or unexplained bleeding - can be a sign of mouth cancer, warns Cancer Research UK.
But for those living in remote parts of the world, where access to a doctor can be difficult, the simple act of checking a patient's tongue can prove hard.
To combat the problem, scientists in India have now developed a new test.
The new diagnostic system, reported in the International Journal of Biomedical Engineering and Technology, works to combine symptoms with a digital analysis of an image of the patient's tongue.
Karthik Ramamurthy, from Rajalakshmi Engineering College in Chennai, and Siddharth Kulkarni and Rahul Deshpande of School of Electronics Engineering at VIT University, have developed the new software.
The neural network can take 'soft inputs' - standard questions about symptoms - and a digital image of a patient's tongue to help offer a likely diagnosis.

It aims to help decide if a professional healthcare worker should be sought out for further advice.
The digital images of the patient's tongue reveal discolouration, engorgement, texture, and other factors linked to various illnesses.
The team's automated diagnosis, however, ultilises the condition of the tongue in combination with other symptoms, to identify whether a patient has a common cold, flu, bronchitis, stretptococcal throat infection, sinusitis, allergies, asthma, pulmonary edema, and food poisoning.
In its current form the system allows diagnosis of 14 distinct conditions.
But the team hope they can soon add images of patient's eyes to use as additional information, thus extending the system's repertoire significantly.
