Surgeons are developing a new smartphone-based tool that can detect urethral or urine blockage, potentially making it easier for patients to test themselves for the condition from the comfort of their own homes.
The novel technique could take high-speed photography which could capture subtle differences between a normal steady stream of liquid and a stream of liquid with an obstruction.
Urethral strictures are a slowing or blocking of the natural flow of urine due to an injury or infection. It is normally diagnosed by uroflowmetry, a test administered at a physician’s office.
“The problem is that patient follow-up after we treat this condition is very poor,” said Matthew Gretzer, Associate Professor at the University of Arizona in the US.
“But we need patients to come back to our clinic for a uroflow test to determine if the obstruction is still present,” he added.
In order to test Gretzer’s hypothesis on high-speed photography, the team created a model of a urethral structure using tubing hooked to a saline bag that could drain through.
Saline fluid was passed through the tubing with and without blockages, created using 3D printed strictures, placed within the tubing. High-speed photography captured both the regular and blocked stream of liquid exiting the tube.
Gretzer contended that photos can be a medium to diagnose blockages and he hopes that patients could send him these images to analyse and make the diagnosis. He plans to create a mobile app which can be downloaded by the patients.
“All patients would need to do is take high-speed images of their urine flow using a strobe light,” Gretzer said.
“Strobe light apps are readily available right now for people to use on their phones”.
According to the researchers, as fluid exits an opening, a natural breakpoint occurs where the liquid stream forms droplets, but with obstructions in place, it changes.
The results showed that by analysing photos, they could measure the length to this point of droplet formation. This length then directly related to the presence of an obstruction in the tube. (IANS)
Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles. Addressing the pop star by her real name, the PM said: "Robyn Rihanna Fenty tomorrow morning shall have conferred upon her the order of national hero of Barbados."
Rihanna was then summoned from her seat to accept the honor, with the Prime Minister managing to rouse a laugh from the singer when she referenced her 2012 hit 'Diamonds', reports femalefirst.co.uk. She added: "On behalf of a grateful nation, but an even prouder people, we therefore present to you, the designee, for the national hero of Barbados." "And to accept on behalf of a grateful nation - you can come my dear - ambassador Robyn Rihanna Fenty, may you continue to shine like a diamond and bring honor to your nation." Rihanna, who was born in the St Michael parish of Barbados, found fame in 2005 after being spotted by a record producer and has since gone on to become one of the most successful female artists of all time with sales of over 250 million and recently reached billionaire status through her Fenty beauty brand.
The Prime Minister continued in her speech: "Commanding the imagination of the world through the pursuit of excellence, her creativity, her discipline, and above all else, her extraordinary commitment to the land of her birth. "Having satisfied that, Ambassador Robyn Rihanna Fenty has given service to Barbados which has been exemplified by visionary and pioneering leadership, extraordinary achievement and the attaining of the highest excellence to the Government of Barbados." It comes after a historic move for Barbados, which has become a republic after almost 400 years and welcomes its first president, Sandra Mason, after removing Queen Elizabeth as head of state.

Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.
Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.

Glaucoma is a condition that damages the nerve of the eye. The increased pressure in the eye, which is known as intraocular pressure, can damage the optic nerve which is responsible for sending images to the brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years. According to WHO, there are different kinds of glaucoma, though, the two most common are, primary open-angle glaucoma (POAG), having a slow and slow and asymptomatic onset, and angle-closure glaucoma (ACG), which is less common, yet more acute. Hence, it is important for everybody over the age of 40 years to have a regular eye check-up.
The eye disorder may be treated with the help of eye drops prescribed by Ophthalmologist. There are various options available to lower intraocular pressure to the desired level. Depending upon the need of the patient, doctor may recommend combinations of eye drops, but it is of utmost importance to use the drops on a regular basis. However, consulting a specialist should be the first priority if diagnosed with glaucoma, but most of the population will first opt for home remedies then will consult chemists' shops for medicines and if the issue is still not resolved then will they think of a specialist. There is a need to modify the mindset of the people and when it comes to sensory organs zero negligence rule should be followed.

Awareness is the key to managing Glaucoma better. The need of the hour is to include eye care as part of the health check-up. Timely detection of Glaucoma will lead to proper medication and diagnosis by an Ophthalmologist. Talking about prevention, early detection will help in managing glaucoma before significant damage occurs. Glaucoma can be because of genetics as well hence knowing the family's eye history is important. Regular and moderate exercise may help prevent glaucoma by reducing eye pressure also eye drops can significantly reduce the risk that high pressure will progress to glaucoma.
Also, there are few home remedies that anyone can follow to avoid glaucoma. Consuming healthy food, using eyewear, avoiding head-down position, keeping oral hygienic, and protecting eyes from sunlight are a few of such remedies. One should be mindful of the fact that Glaucoma is irreversible blindness and awareness can help us in fighting it. Depending on the condition an Ophthalmologist may prescribe an oral medication or may suggest therapies. In severe conditions, doctors can also recommend surgeries like Laser therapy, Filtering surgery, Drainage tubes, minimally invasive glaucoma surgery (MIGS). (IANS/ MBI)
