A 7-year-old boy was brought with progressive difficulty in walking and urinary incontinence. On inspection, a tuft of hair and dimple were noted over the lower back. Neurological examination revealed spasticity, weakness in the lower limbs, and diminished reflexes. MRI spine showed spina bifida occulta with tethered cord syndrome. The child was referred to neurosurgery for surgical release of the tethered cord. Parents were counseled that surgery could halt progression but some deficits may persist. They were educated on the importance of early recognition of cutaneous markers over the spine in infants.

Types of Sound by Frequency & Some Interesting Facts

1. Infrasound (Below 20 Hz)
Infrasound is a low-frequency audible sound that is oftentimes below 20 Hz. Infrasounds can be caused by various sources, such as winds, storms, earthquakes, volcanoes, and even wind turbines
This is sound too low for the human ear to detect. We can’t hear it, but elephants rely on it to communicate across kilometers, and nature produces it. Because of its long wavelength, infrasound can travel very far and even move through the ground.

2. Audible Sound (20 Hz – 20,000 Hz)
This is the range humans live in — everything from deep bass to high-pitched tones fits here. It’s also the range most musical instruments and everyday sounds fall into.
An interesting twist is that our sensitivity to higher frequencies fades with age, which is why teenagers often hear sounds their parents can’t.

3. Ultrasound (Above 20,000 Hz)
Sounds waves having frequency more than 20kHz are called Ultrasound.
These high-frequency sounds are inaudible to us but extremely useful to other species. Bats and dolphins navigate with ultrasound like built-in sonar, while dogs respond to ultrasonic whistles. In medicine, it’s a cornerstone of imaging — diagnostic ultrasound typically uses 2 to 20 MHz to visualize organs, vessels, and fetuses.

Facts;
Each type of sound has its own world: elephants “speak” in low rumbles we’ll never hear, dogs catch signals we miss, and bats essentially “see” with sound. Humans, even though limited to the audible range, have found ways to harness both infrasound and ultrasound for science, safety, and medicine.

Dengue

Dengue is a viral disease transmitted to humans through the bite of an infected Aedes aegypti mosquito. It is common in tropical and subtropical regions, especially during the rainy season.

🔹Symptoms

Sudden high fever (up to 104°F)
Severe headache
Pain behind the eyes
Muscle and joint pain (“break-bone fever”)
Nausea and vomiting
Skin rashes (red spots on the body)
In severe cases: bleeding from nose, gums, or under the skin called Dengue Hemorrhagic Fever.

🔹Causes

Bite of an infected Aedes mosquito.
Mosquitoes breed in clean, stagnant water (tires, flower pots, water tanks, coolers, etc.)

🔹Treatment

No specific antiviral medicine for dengue.
Rest, fluids, and hydration are very important.
Paracetamol is used for fever (avoid aspirin and ibuprofen because they can cause bleeding).
In severe cases, hospital care and platelet monitoring are necessary.

🔹Prevention

Use mosquito nets and repellents.
Wear full-sleeve clothes.
Remove stagnant water around the house.
Use mosquito sprays regularly.
