Pesquisadores identificam uma nova estrutura glandular na região da cabeça!

Uma revelação científica notável trouxe à luz um grupo de glândulas salivares que permanecia oculto no corpo humano, especificamente na região superior da garganta.

A descoberta ocorreu quando uma equipe do Instituto de Câncer da Holanda realizava exames de imagem do tipo PSMA PET/CT — um método de alta precisão comumente usado para detectar câncer de próstata. Durante as análises, os especialistas observaram, de forma inesperada, uma área com intensa atividade localizada atrás da cavidade nasal.

As imagens mostraram duas glândulas simétricas e de tamanho considerável em uma zona em que se presumia haver apenas estruturas salivares microscópicas. A presença dessas glândulas foi verificada em cada um dos 100 pacientes participantes do estudo, indicando que se trata de um traço anatômico comum, que permaneceu não identificado até o presente momento.

Denominadas “glândulas tubárias”, acredita-se que essas formações tenham a função de umedecer a região posterior da garganta durante processos como a fala e a deglutição. A identificação dessas glândulas pode ter grande impacto em terapias contra câncer de cabeça e pescoço. Como as glândulas salivares são extremamente vulneráveis à radioterapia, protegê-las durante o tratamento pode evitar complicações como xerostomia (secura bucal persistente), alterações na fala e maior susceptibilidade a infecções.

Embora ainda se investigue se essa estrutura deve ser classificada como um novo órgão ou como parte do sistema glandular já conhecido, a descoerta já está influenciando tanto o campo da anatomia humana quanto as práticas clínicas em oncologia.

A groundbreaking study from Wuhan University is turning everything we thought we knew about Parkinson’s disease upside down. Researchers now believe the disease may not start in the brain at all, but in the kidneys.
The study found abnormal clusters of alpha-synuclein (α-Syn) proteins, the same ones heavily linked to Parkinson’s, inside the kidneys of affected patients. These proteins are known to trigger neurological damage when they build up in the brain. However, in animal experiments, healthy kidneys successfully cleared these proteins. When kidney function was impaired, the α-Syn proteins began to travel to the brain, setting the stage for Parkinson’s.
Shockingly, even people with chronic kidney disease but no neurological symptoms were found to have α-Syn buildup. This discovery suggests the kidneys might act as an early “reservoir” for toxic proteins, which could later spread through the bloodstream or nerves and affect the brain.
Though early and based on limited data, this research could completely change how we understand and treat Parkinson’s. It raises the possibility that monitoring and protecting kidney health might one day help prevent or delay the onset of this devastating condition.

💥 Ischiofemoral impingement Syndrome💥
➡️Hidden Cause of Deep Hip & Back Pain

⁉️ Ischiofemoral pain syndrome is a rare condition caused by narrowing of the space between the ischial tuberosity and the femur (usually the lesser trochanter). This narrowing compresses the quadratus femoris muscle, leading to hip and buttock pain.

---

💥Causes:

✅ Congenital or acquired narrowing of the ischiofemoral space
✅ Hip trauma or fractures
✅ Previous hip surgery (e.g., total hip arthroplasty, osteotomy)
✅ Tumors or space-occupying lesions
✅ Overuse injuries (especially in athletes, dancers, runners)

---

💥 Signs & Symptoms:

⚡ Deep buttock or groin pain
⚡ Pain radiating to the posterior thigh
⚡ Pain worsens with hip extension, adduction, and external rotation
⚡ Difficulty in walking long distances
⚡ Tenderness over quadratus femoris region
⚡ Sometimes snapping or catching sensation in the hip

---

💥 Biomechanics & Pathophysiology

🤷‍♀️ The ischiofemoral space (distance between ischial tuberosity and lesser trochanter) is normally 18–23 mm.
🤷‍♀️ Narrowing below this range leads to impingement of the quadratus femoris muscle.
🤷‍♀️ Chronic compression → muscle edema, tears, fibrosis, and inflammation → persistent pain.

---
💥 Diagnosis & Assessment

🗣️ Clinical Tests:

1️⃣ Pain reproduction with hip extension + adduction + external rotation
2️⃣Palpation tenderness in deep buttock

💥 Radiology:

🩸 MRI → shows narrowing of ischiofemoral space (

🦵 Tibial nerve origin and pathway
• Branches from the sciatic nerve slightly above the popliteal fossa
• Runs behind the knee
• Passes through the tarsal tunnel around the medial malleolus

🦶 Plantar nerve branching
• Branches to the medial and lateral plantar nerves around the tarsal tunnel
• Pe*****te into the fascia of the abductor hallucis muscle
• Run from the sole to the toes
• Innervate the sensory of the anterior part of the plantar

⚪ Medial calcaneal nerve
• Branches from the posterior tibial nerve at the proximal end of the tarsal tunnel
• Pierces the flexor retinaculum
• Innervates the sensory of the medial calcaneus

🏗️ Tarsal tunnel structure
• Composed of a rigid bone at the bottom
• Covered by the flexor retinaculum

📍 Structures passing through the tarsal tunnel
• Tibialis posterior tendon
• Flexor digitorum longus tendon
• Posterior tibial artery and veins
• Posterior tibial nerve
• Flexor hallucis longus tendon

🔗 Neurovascular relation
• Posterior tibial nerve runs with the posterior tibial artery and veins in the tarsal tunnel

⚠️ Clinical relevance
• Because of these anatomical features, the posterior tibial nerve may be damaged at the tarsal tunnel (tarsal tunnel syndrome: TTS)
• TTS was first reported by Keck and Lam in 1962 [1, 2]

Não é incomum notar que algumas pessoas têm veias mais aparentes, que saltam pelo corpo. E bem, elas são responsáveis por reter quase 75% do sangue do nosso corpo, além de manter a circulação em funcionamento. Por isso, é importante mantermos atenção a elas, mas não é preciso se assusta...

In a groundbreaking advancement for regenerative medicine, Japanese researchers have enabled a paralyzed man to stand using induced pluripotent stem cells (iPS). This innovative therapy involves reprogramming adult skin or blood cells into neural precursor cells capable of repairing damaged spinal cord tissue. Led by Dr. Hideyuki Okano and officially approved for clinical trials in Japan, the approach marks a significant step toward reversing paralysis.

Unlike conventional treatments that focus on managing symptoms, this method aims to rebuild lost neural connections. The early outcomes are highly encouraging, suggesting the potential to transform rehabilitation for spinal cord injuries and trauma patients worldwide. As further trials progress, Japan stands at the forefront of a medical revolution—one that could make permanent paralysis a thing of the past.

Sciatica is pain that radiates along the sciatic nerve, which runs from the lower back through the hips and buttocks down each leg. It typically affects one side of the body.

Causes of Sciatica:
• Herniated disc (most common)
• Spinal stenosis
• Degenerative disc disease
• Spondylolisthesis
• Piriformis syndrome
• Trauma or injury
• Pregnancy-related changes

Symptoms:
• Sharp or shooting pain in the lower back, buttock, and leg
• Tingling, numbness, or muscle weakness in the leg or foot
• Pain worsens with sitting, coughing, sneezing, or bending
• Burning or electric-shock-like pain

Physiotherapy Treatment for Sciatica:

1. Pain Relief Techniques:
• Hot or cold packs
• TENS therapy (Transcutaneous Electrical Nerve Stimulation)
• Ultrasound therapy

2. Stretching Exercises:
• Piriformis stretch
• Hamstring stretch
• Knee-to-chest stretch

3. Strengthening Exercises:
• Core strengthening
• Pelvic tilts
• Glute bridges

4. Postural Training:
• Correcting posture while sitting, standing, and lifting
• Ergonomic advice for work and daily activities

5. Manual Therapy:
• Soft tissue mobilization
• Joint mobilization for lumbar spine and sacroiliac joint

6. Neural Mobilization:
• Sciatic nerve glides to reduce neural tension
