Bow Hunter's Sydrome
Bow Hunter's syndrome is an uncommon condition in which the vertebral arteries is symptamatically occuled during neck rotation. This mechanical occlusion or stenosis can sometimes result into a Bow Hunter's stroke. As we all know, the vertebral arteries supply blood to the posterior part of the brain by way of the basilar artery and then the posterior cerebral arteries. In some special cases of Bow hunter's syndrome, patients can have what appears to be a normal vertebral artery on one side but on the opposite side can have an occluded artery while their head is in a nuetral position. Usually one of the vertebral arteries become occuled when turning their head a specific degree to one side while the other side becomes occluded in the c1-c2 area of the cervical spine. Stenosis of the vertebral artery can be in result of a cervical spine abnormality that pinches the blood flow when traveling through the transverse foramen. Angiography is the most common procedure preformed to find the occlusion or stenosis of the artery. In most cases a vertebral angiography can locate where in the artery the occlusion originates or depicts the mass or tumor causing stenosis.
SYMPTOMS:
Are typically the same as in other stroke victims: dizziness, vision disturbance, trouble speaking and walking, confusion and severe headaches.
The damage will start immediatly after the infarction occurs. If ever experiencing these symptoms go to the nearest emergency room for medical assistance. The sooner the better for a chance at full recovery.
TREATMENT:
Angiography followed by and interventional procedure angioplasty and stenting.

Chronic Sinusitis
Nasal polyps
Cystic fibrosis
Nasal obstruction
Other symptoms are:
Ear pain
Sore throat
Bad breath(halitosis)
Fatigue or irrtability
NAUSEA
Causes of chronic sinusitis may be causesd by a variety of reasons:
Viral, bacterial & fungal growth
Allergic diseases
Autoimmunity diseases
When to see a Doctor ?
You may have several episodes of acute sinusitis that last more than four weeks and keep reoccuring before developing chronic sinusitis. You may be reffered to an ear, nose and throat specialist for evaluation and treatment. See a doctor if you have:
If you have sinusitis a number of times and condition fails to respond to treatment.
If you sinusitis that last more than 7 days.
Treatments:
Saline nasal sprays
Oral, Injected, or Nasal corticosteroids
Decongestants
Over the counter drugs:(
Aspirin-NEVER GIVE ASPIRIN TO CHILDREN
Test and diagnosis:
Nasal Endoscopy
Imaging studies
Nasal ans sinus cultures
Allergy test

Empty sellar syndrome
Empty sella syndrome is the apperance, by a radiograph, that shows the sella turcica which usually houses the pituritaty gland, empty! After making a statement like this, one might ask how can a human function without the presence of the body's most important endocrine gland. After all, it only plays a major role in regulating the body's entire endocrine system by producing secretions that controls other endocrine glands that influence growth, metabolism and maturation. I don't mean to harp on this but the pituitary gland plays a part in every physiolocial process in the body. However, there is a reason for everything and the empty space is not always truly empty.
In Primary ESS, the voided appearance is a result of CSF that has entered the space normally occupied by the pituitary and has compressed the hypophysis against the wall of the sella turcica. Secondary ESS is the result of the pituitary gland regressing within the cavity after an injury, surgery or radiation therapy. Disease or tramua may reduce the size of the pituitary or completly eliminate it! Statistics from autopsies show that 5% to 25% empty sellar syndrome is found incidentally.
Causes and Symptoms
There are no known triggers or causative factors that relates to Primary ESS. Because of the unknown etiologic factors it is thought to be a congenital and accidental occurence by a failure or opening of the diaphragma sella. Secondary ESS is an acquired cause through a medical procedure, disease or truama. All of these reasons can contribute to the reduction in size or a complete absence of the gland. Sheehan's syndrome, is a specific type of acquired empty sellar syndrome, that is caused by infarction of the pituitary induced by shock or hemorrhage after labor and delivery.
Primary ESS: symptoms are usually associated with obesity and high blood pressure in women.
Secondary ESS: the condition is a byproduct of some other process leading to destruction and loss of pituitary functions, such as the ceasing of mestrual periods, inpotence, infertility, fatigue and an intolerance to stress and infection.
TREATMENT
Replacement therapy for any deficient hormone. All treatment would be symptomatic and supportive.
DIAGNOSIS
Empty sella syndrome is always diagnosed by some type of imaging study of the brain (x-ray, ct or mr)
PROGNOSIS
ESS is not a life-threatening illness but is a lifelong illness.

Labrynnitis
Loss of balance, such as falling toward one side.
Nausea and vomiting
Tinnitus or other noises in the ear
In structure, the labyrinth is a group of interconnected canals and chambers that houses the vestibular system of the inner ear. The vestibular system is made up of three semicircular canals that sense changes in rotational motion, gravity and linear motion. The brain combines visual cues with sensory signals from the semicircular canals to determine adjustments needed to retain balance. Labyrinthitis is caused by the inflammation of the labyrinth. When inflammation occurs the signal from the semicircular canals to the brain becomes affected resulting in it's most prominent and debilitating symptom acute vertigo.
