The crossing of the spinothalamic tract. (1/5)The question whether the spinothalamic and spinoreticular fibres cross the cord transversely or diagonally was investigated in cases of anterolateral cordotomy and in a case of thrombosis of the anterior spinal artery. The pattern of sensory loss following transection of the anterolateral quadrant of the cord consists of a narrow area of decreased nociception and thermanalgesia at the level of the incision; it extends for 1-2 segments cranial and cordal to the incision. This area is immediately cranial to the area of total loss of these modalities. This pattern of sensory loss is explained as follows. The cordotomy incision transects two groups of fibres: those that are already within the anterior and anterolateral funiculi and those that are crossing the cord. The area of total thermanaesthesia and analgesia is due to transection of fibres that are already within this region. The area of partial sensory loss is due to transection of the fibres that are crossing the cord at that level. Owing to the craniocaudal extent of the branches of the dorsal roots, there is an overlap of their collaterals that results in every spinothalamic neurone receiving an input from several dorsal roots. The narrow cordotomy incision thus divides the few fibres crossing at that level, causing diminished noxious and thermal sensibility over a few segments above and below the incision. These facts can be accounted for only on the assumption that these spinothalamic fibres are crossing the cord transversely. This evidence of transverse crossing was found in the cervical, thoracic and lumbar segments. There were three of 63 cordotomies for which this explanation of the partial sensory loss could not be maintained. Although no explanation has been suggested, this is unlikely to be due to the fibres crossing the cord diagonally. (+info)
Anterior spinal artery syndrome in a girl with Down syndrome: case report and literature review. (2/5)BACKGROUND/OBJECTIVE: Anterior spinal artery syndrome is an extremely rare cause of acute ischemic cord infarction in children. It is caused by hypoperfusion of the anterior spinal artery, leading to ischemia in the anterior two thirds of the spinal cord. The presentation is usually with an acute and painful myelopathy with impaired bladder and bowel control. Pain and temperature sensation below the lesion are lost, whereas vibration and position sense is intact because of the preservation of the posterior columns. METHODS: Case report. RESULTS: A 16-year-old girl with Down syndrome presented with urinary retention and acute complete flaccid paralysis of the legs with absent deep tendon and abdominal reflexes. Magnetic resonance imaging showed a signal abnormality in the anterior half of the thoracic cord from T5 to T12, consistent with anterior spinal artery infarction. CONCLUSIONS: Pediatricians should consider anterior spinal artery syndrome in the child who presents with acute, painful myelopathy. We summarize the etiology, neurological findings and outcomes of 19 children found in the literature with anterior spinal artery syndrome. (+info)

Anterior spinal cord syndrome in a patient with Behcet's disease. (5/5)Although neurological involvement in Behcet's disease is not so uncommon, isolated spinal cord disease is quite rare and reported to be observed in about 2% of all cases with neurological involvement. Here we report a Behcet's patient with spinal cord disease presented with anterior spinal cord syndrome. This rare syndrome is caused by hypoperfusion of the anterior spinal artery and to our knowledge has not been previously reported in patients with Behcet's disease. This report defines the characteristic clinical features of this entity and emphasizes the importance of early immunosuppressive treatment and initiation of rehabilitation. (+info)
The term "syndrome" refers to a collection of symptoms that together form a distinct clinical picture or pattern. In the case of Anterior Spinal Artery Syndrome, the specific symptoms that are present depend on the location and severity of the injury or obstruction affecting the anterior spinal artery.
Some common symptoms of Anterior Spinal Artery Syndrome include:
* Weakness or paralysis in one or both legs
* Numbness or tingling sensations in the legs, buttocks, and lower back
* Bladder dysfunction, such as urinary retention or incontinence
* Loss of sensation in the anal region
* Pain in the lower back, hips, or legs
* Difficulty walking or maintaining balance
The exact cause of Anterior Spinal Artery Syndrome can vary, but some common causes include trauma to the spine (such as a car accident or fall), tumors, infections, and blood vessel diseases. Diagnosis is typically made through a combination of physical examination, imaging studies such as MRI or CT scans, and other tests. Treatment options for Anterior Spinal Artery Syndrome depend on the underlying cause and severity of the condition, but may include medications, surgery, or rehabilitation therapy.
The term "infarction" is derived from the Latin words "in" meaning "into" and "farcire" meaning "to stuff", which refers to the idea that the tissue becomes "stuffed" with blood, leading to cell death and necrosis.
Infarction can be caused by a variety of factors, including atherosclerosis (the buildup of plaque in the blood vessels), embolism (a blood clot or other foreign material that blocks the flow of blood), and vasospasm (constriction of the blood vessels).
The symptoms of infarction vary depending on the location and severity of the blockage, but can include chest pain or discomfort, shortness of breath, numbness or weakness in the affected limbs, and confusion or difficulty speaking or understanding speech.
Diagnosis of infarction typically involves imaging tests such as electrocardiograms (ECGs), echocardiograms, or computerized tomography (CT) scans to confirm the presence of a blockage and assess the extent of the damage. Treatment options for infarction include medications to dissolve blood clots, surgery to restore blood flow, and other interventions to manage symptoms and prevent complications.
Prevention of infarction involves managing risk factors such as high blood pressure, high cholesterol, smoking, and obesity, as well as maintaining a healthy diet and exercise routine. Early detection and treatment of blockages can help reduce the risk of infarction and minimize the damage to affected tissues.
SMAS is caused by a rare congenital anomaly, where there is a narrowing or strangulation of the third portion of the duodenum due to compression between the superior mesenteric artery and the pancreas. This condition can also be caused by inflammatory conditions such as pancreatitis or peripancreatic tissue fibrosis, or as a result of trauma.
The symptoms of SMAS may vary in severity and may be intermittent or persistent. They typically begin after eating and may be relieved by vomiting. The most common symptoms include abdominal pain, nausea, vomiting, weight loss, and fever. Patients with severe compression may develop bleeding, perforation, or gangrene of the duodenum, which can lead to life-threatening complications.
SMAS is diagnosed based on a combination of clinical symptoms, laboratory tests, and imaging studies such as endoscopy, CT scan, or MRI. Endoscopy is the most common method used for diagnosis, which can reveal compression of the duodenum between the superior mesenteric artery and the pancreas.
Treatment of SMAS depends on the severity and cause of the condition. Mild cases may be treated with conservative management, including dietary modifications, antacids, and anti-inflammatory medications. In severe cases, surgical intervention may be necessary, such as duodenal resection or pancreatic neurolysis.
Prognosis for patients with SMAS depends on the severity of the condition and the promptness and effectiveness of treatment. With early diagnosis and appropriate management, most patients can experience significant symptom relief and improved quality of life. However, delays in diagnosis or ineffective treatment may lead to complications such as bleeding, perforation, or gangrene, which can be life-threatening.
In conclusion, SMAS is a rare but potentially life-threatening condition that can cause severe compression of the duodenum between the superior mesenteric artery and the pancreas. Early diagnosis and appropriate management are essential to prevent complications and improve outcomes.
Types of Spinal Cord Vascular Diseases:
1. Moyamoya disease: A rare condition caused by narrowing or blockage of the internal carotid artery and its branches, leading to decreased blood flow to the brain and spinal cord.
2. Stenosis (narrowing): A common condition caused by wear and tear or inflammation that can occur anywhere along the length of the spine.
3. Spinal cord infarction: A condition caused by a lack of blood supply to the spinal cord, often due to a blockage or clot in the blood vessels.
4. Vasculitis: An inflammatory condition that affects the blood vessels, including those supplying the spinal cord.
5. Thoracic outlet syndrome: A condition caused by compression of the nerves and blood vessels between the neck and shoulder.
1. Weakness or numbness in the arms or legs
2. Pain in the neck, back, or limbs
3. Difficulty with coordination and balance
4. Bladder or bowel dysfunction
5. Loss of sensation in the arms or legs
6. Tingling or burning sensations in the arms or legs
7. Muscle spasms or stiffness
8. Weakness or paralysis of specific muscle groups
1. Medical history and physical examination
2. Imaging studies, such as MRI or CT scans
3. Blood tests to check for inflammatory markers or signs of vasculitis
4. Angiography or MRA to visualize the blood vessels
5. Electromyography (EMG) to assess muscle function and nerve damage
1. Medications to manage symptoms, such as pain relievers, anti-inflammatory drugs, or corticosteroids
2. Physical therapy to improve range of motion and strength
3. Surgery to release compressed nerves or repair damaged blood vessels
4. Injections of botulinum toxin or other medications to relieve symptoms
5. Lifestyle modifications, such as avoiding heavy lifting or bending, taking regular breaks to rest, and practicing good posture.
The term "hypesthesia" comes from the Greek words "hypo," meaning "under," and "aesthesis," meaning "sensation." It is sometimes used interchangeably with the term "hyperesthesia," which refers to an abnormal increase in sensitivity to sensory stimuli.
Hypesthesia can be caused by a variety of factors, including:
* Neurological disorders such as peripheral neuropathy or multiple sclerosis
* Injury or trauma to the nervous system
* Infections such as Lyme disease or HIV
* Certain medications, such as antidepressants or antipsychotics
* Substance abuse
Symptoms of hypesthesia can vary depending on the individual and the underlying cause, but may include:
* Increased sensitivity to touch, light, or sound
* Exaggerated response to stimuli, such as jumping or startling easily
* Difficulty filtering out background noise or sensory input
* Feeling overwhelmed by sensory inputs
Treatment for hypesthesia depends on the underlying cause and may include:
* Medications to manage pain or inflammation
* Physical therapy to improve sensory integration
* Sensory integration techniques, such as deep breathing or mindfulness exercises
* Avoiding triggers that exacerbate the condition
It is important to note that hypesthesia can be a symptom of an underlying medical condition, and proper diagnosis and treatment are necessary to address any underlying causes. If you suspect you or someone you know may be experiencing hypesthesia, it is important to consult with a healthcare professional for proper evaluation and treatment.
Paraplegia is classified into two main types:
1. Complete paraplegia: Total loss of motor function in both legs and pelvis.
2. Incomplete paraplegia: Some degree of motor function remains in the affected limbs.
Symptoms of paraplegia can include weakness, paralysis, numbness, or tingling sensations below the level of the spinal cord injury. Loss of bladder and bowel control, sexual dysfunction, and changes in sensation (such as decreased sensitivity to touch and temperature) are also common.
Diagnosis typically involves a physical examination, medical history, neurological tests such as reflexes and muscle strength, and imaging studies like X-rays or MRIs to determine the underlying cause of paraplegia. Treatment depends on the specific cause of the condition and may include medications, rehabilitation therapy, and assistive devices such as braces, canes, or wheelchairs.
Treatment options for duodenal obstruction depend on the underlying cause of the condition. Surgery may be required to remove any blockages or scar tissue that is causing the obstruction. In some cases, a stent may be placed in the duodenum to help keep it open. Medications such as proton pump inhibitors and anti-inflammatory drugs may also be used to manage symptoms.
Early diagnosis and treatment of duodenal obstruction are important to prevent complications such as malnutrition, dehydration, and potentially life-threatening infections. It is essential for individuals with suspected duodenal obstruction to seek medical attention promptly if they experience any symptoms.
What is the medical definition of 'Duodenal Obstruction'?
Duodenal obstruction is defined as a blockage or narrowing of the duodenum, which is the first part of the small intestine.
Examples of syndromes include:
1. Down syndrome: A genetic disorder caused by an extra copy of chromosome 21 that affects intellectual and physical development.
2. Turner syndrome: A genetic disorder caused by a missing or partially deleted X chromosome that affects physical growth and development in females.
3. Marfan syndrome: A genetic disorder affecting the body's connective tissue, causing tall stature, long limbs, and cardiovascular problems.
4. Alzheimer's disease: A neurodegenerative disorder characterized by memory loss, confusion, and changes in personality and behavior.
5. Parkinson's disease: A neurological disorder characterized by tremors, rigidity, and difficulty with movement.
6. Klinefelter syndrome: A genetic disorder caused by an extra X chromosome in males, leading to infertility and other physical characteristics.
7. Williams syndrome: A rare genetic disorder caused by a deletion of genetic material on chromosome 7, characterized by cardiovascular problems, developmental delays, and a distinctive facial appearance.
8. Fragile X syndrome: The most common form of inherited intellectual disability, caused by an expansion of a specific gene on the X chromosome.
9. Prader-Willi syndrome: A genetic disorder caused by a defect in the hypothalamus, leading to problems with appetite regulation and obesity.
10. Sjogren's syndrome: An autoimmune disorder that affects the glands that produce tears and saliva, causing dry eyes and mouth.
Syndromes can be diagnosed through a combination of physical examination, medical history, laboratory tests, and imaging studies. Treatment for a syndrome depends on the underlying cause and the specific symptoms and signs presented by the patient.
