Spring finger is what disease?

People with spring fingers have lumps in their palms, have difficulty folding or stretching their fingers, especially in the morning.

According to Dr. Nguyen An Phap, University Hospital of Medicine and Pharmacy in Ho Chi Minh City, spring fingers are also called pop fingers or trigger fingers. The disease is most common in women between the ages of 35 and 60. It is caused by the stickiness between the folding finger and the pulley holding the tendon, causing the folded tendon to stick to the pulley, preventing the finger from stretching.

The disease is common in professionals who have to use their fingers regularly such as teachers, office workers, tailors, typists … People with endocrine disorders such as diabetes, gout also often .

Symptoms of spring fingers usually begin without any injury or after a period of heavy work. Symptoms include soft lumps in the palm of the hand, swelling, pain when folding or straightening fingers. In severe cases, the finger cannot straighten, possibly with one or more fingers.

French doctor said that finger spring disease, if detected and treated early, can avoid complications, short treatment time, save costs, less affect life and work.

The treatments
Non-surgical treatment
Patients with mild conditions can take analgesic anti-inflammatory drugs and apply physical therapies such as ultrasound, wax dip, exercise, finger splint … When taking medicine and physiotherapy If the patient responds well, the patient will receive the medication.

Treatment with surgery
If the disease is severe, prolonged and does not meet the above measures, the doctor will order minor surgery.

Traditional medicine
While waiting for surgery, the acupuncture or implantation method will only help the patient relieve pain, reduce inflammation. Patients can combine with physiotherapy to treat faster.

Traditional medicine combined with non-pharmacological treatments helps patients limit the use of anti-inflammatory analgesic drugs, resolving many symptoms.

French doctors advise patients to be carefully examined at health facilities to know the exact cause. From there, the doctor will recommend the appropriate course of treatment.

Mammals die in mass after each mating season

The immune system of male kaluta marsupials weakens because they mate with many mates for a short time, leading to mass deaths.

The researchers found interesting new details about the unusual and unusual mating habits of the kaluta (Dasykaluta rosamondae), a small marsupial like a rat distributed only in arid Pilbara region in northwestern Australia. According to research published in the journal Zoology, male kaluta die in large numbers after a mating season.

Mating activity causes male kaluta to be so stressed and exhausted that the immune system is weakened. This is not surprising because they mate with multiple sex partners for a short week, sometimes lasting 14 hours at a time.

“We regularly catch healthy males throughout the study, except immediately after the mating season. Along with other field and laboratory studies, this indicates a dead row. male kaluta series, “said Genevieve Hayes, head of research at the University of Western Australia’s School of Biology.

Female Kaluta can store sperm from multiple mates and mate regularly with different males. They can lay 8 offspring from the sperm of three mates. “That means the male kaluta must mate a lot and have good sperm quality to defeat the rival. This sacrifice for reproductive purposes seems like a fatal blow to them,” Hayes said.

Mating behavior that causes a series of male deaths in the first season is called “male semelparity”. Due to the harsh nature, this breeding strategy is very rare in the animal kingdom. In fact, scientists know quite a few of these mating species, most of which are invertebrates.

Kaluta belongs to the marsupial family of Dasyuridae, comprising 61 species. According to the researchers, they are located in a different branch of the evolutionary tree than other species of the same family.
