What are Neglected Tropical Diseases?

 Recently, India joined the world and Light Up Qutub Minar as a sign of unity to combat the Neglected Tropical Diseases (NDT).

Highlights

  • This was done to mark the second annual World NTD Day that will be observed on January 30th.
  • The World Neglected Tropical Diseases Day highlights the global community’s commitment to end the diseases.
  • The NDT diseases cause immeasurable suffering among the most marginalized communities of the world.
  • On the occasion of World NTD day, 50 landmarks representing the 25 nations of the world will be lit up. They will celebrate how far the world have come together in beating the NTD.

What are Neglected Tropical Diseases (NTD)?

  • The NTDs are a diverse group of communicable diseases that prevail in tropical and subtropical conditions.
  • These diseases affect more than one billion people every year. In combating the disease, the countries invest billions of dollars every year.
  • The Populations who are living in poverty, where there is no adequate sanitation, those who are in close contact with infectious vectors, domestic animals & livestock are highly affected by such diseases.
  • As per the WHO major NTDs are: Buruli Ulcers, Chagas Disease, Dengue, Chikungunya, Sleeping Sickness (Human African Trypanosomiasis), Hansen’s Disease (Leprosy), Trachoma Mycetoma, chromo-blastomycosis, deep mycoses etc.

NTD cases in India

  • As per the data, one in five people across the world are affected by NTD.
  • India is home to the world’s largest absolute burden of 11 of the major neglected tropical diseases.

World NTD Day

It is an awareness day that addresses the neglected tropical diseases (NTDs). World NTD Day was celebrated on January 20, 2020 for the first time.  The date, January 30, marks the anniversary of the 2012 London Declaration on NTDs. The London declaration had unified the partners across sectors, countries and disease communities for a greater cooperation, investment and action on NTDs.

What is “Blue Jet Lightning”?

 The Scientists from the International Space Station (ISS) have observed a bright-blue lightning bolt that is shooting upward from the thunderclouds. Such blue jets are hard to observe from the ground because the electrical discharges emerge from the tops of thunderclouds. But from space, one can easily observe the phenomenon.

Highlights

  • The instrument at the space station had captured a blue jet shooting from the thunderstorm cell near a small island in the central Pacific Ocean on February 26, 2019.
  • Scientists had observed the five intense flashes of blue light.
  • Each of the lighting lasting about 10 to 20 milliseconds.
  • After that, the blue jet moved out from the cloud towards a narrow cone shape stretching into the stratosphere.

What are blue jets?

  • Blue jets are initiated as “normal” lightning discharges.
  • It emerges between the upper positive charge region in a thundercloud and a negative screening layer above the charge region.
  • The positive end network fills the negative charge region and after that the negative end fills the positive charge region.
  • After that, the positive end exits the cloud and starts propagating upward.
  • Earlier, it was believed that blue jets are directly related to lightning flashes but it is the result of the hails.
  • The blue jets are brighter than sprites and are blue in colour.
  • The blue colour of the jets is the result of blue and near-ultraviolet emission lines from neutral and ionized molecular nitrogen.
  • The blue jets were recorded on October 21, 1989 for the first time.

Thunderstorm

It is also known as an electrical storm or a lightning storm. It is characterized by the presence of lightning and the acoustic effect on the Earth’s atmosphere that is thunder. This phenomenon is usually taking place in the cumulonimbus cloud, the thunderstorm is also accompanied by strong winds and heavy rain. It could also lead to snow, sleet, or hail.

Cumulonimbus Cloud

It is a dense and towering vertical cloud. This cloud is formed by the water vapor which is carried by the powerful upward air currents.

The role of occupational therapy for children with learning disabilities

 Seema is six years old and in class 1. Her parents consulted me because despite knowing her classwork and answering everything orally in class, her teacher found that she could not copy from the board, had incomplete written work and had alphabets and number reversals. This is an example of Learning Disability (LD), a challenge that occupational therapists often need to work with.

LD is a diagnosis that encompasses difficulties in processing information, manifested as problems with the 3Rs: reading (dyslexia), writing (dysgraphia) and arithmetic (dyscalculia). In addition to having one or more types of learning difficulties, children with LD also present with some other coexisting diagnoses like attention-deficit/ hyperactivity disorder (ADHD), anxiety disorders, depression and tics. Though not intellectually challenged, as reflected in a normal IQ, children with LD have difficulties with academic performance. Studies suggest that 5-15 percent of children in India have a type of learning disability.

Occupational Therapy is a branch of medicine that helps individuals optimise their performances in meaningful activities that occupy their time. For children, this would comprise school, play, and social interaction with friends. Children with LD have difficulties in each of these areas and an occupational therapist helps improve sensory processing skills (understanding, registering and responding to sensory information), fine motor skills (required for writing), attention (by improving sitting tolerance), and social behaviour (interacting with peers). Occupational therapists work on rewiring the brain to enhance such behaviour. This is achieved through meaningful activities that are motivating and fun to children, helping them practice a skill and retain it. For example, an OT session could include sensory based play using swings, monkey bars and obstacle courses, fine motor activities through board games and adaptive aides like the iPad to enhance time management and visual attention.

Sensory processing is the ability of the brain to receive information from sense organs such as the eyes, ears, joints, and skin, process it, and help the body give an appropriate response. Examples would be responding to the teacher, reading something, standing in line for assembly, writing something down or sitting straight. OT works on improving sensory processing using sensory play and goal-directed interventions. Fine motor skills are also targeted through various games used to build muscles and strengthen small hands, helping them hold pencils longer and write faster. OTs today employ visual schedules and timers as aides to help make the concept of time more concrete for children who have difficulty paying attention or are disorganised.  Technology is also being used as a tool to help children with LD.

OT is a big proponent of early intervention where the motto is “the younger the child, the better the outcome.” This being said, it is important to remember that the brain can constantly rewire itself and therapy will continue to work at any age as long as the child is presented with innovative challenges that keep her/him engaged.
