As was discussed within the 1st write-up of this three-part series, neurologists who face a patient with feasible Parkinson’s have no definitive test: no scans, no blood tests or spinal taps with which to base their diagnosis. Parkinson’s Disease is what’s referred to as a “clinical diagnosis.” this indicates that the choice as to whether or not or not a patient really has Parkinson’s demands an extensive face to face interaction having a neurologist. that meeting generally entails a thorough history-taking or interview, along with a comprehensive physical examination. Even though extremely frequently videotaping or other aids are utilized, the diagnosis completely depends on the clinical acumen of the neurologist as he/she investigates what the patient presents in word and on exam.

To sum up the approach extremely briefly, whilst interviewing and examining the patient, the neurologist creates a running list of possibilities in his/her head. this list is known as the “differential diagnosis,” frequently referred to a just the “differential.” a great neurologist a lot like a great detective, keeps adjusting, refining the differential as if it had been a list of suspects. He/she redirects the line of questioning and also the focus of the physical exam based on ruling in and ruling out suspects.

Every of the findings assists the neurologist to continuously reshuffle and re-prioritize the differential. As the list narrows to just a couple of possibilities, he/she will ask further questions and refine the examination. Then the patient is sent for tests that may rule out other possibilities. for example, patients get a brain CT or MRI not to diagnose Parkinson’s but to rule out bigger structural causes that may mimic Parkinson’s symptoms like a brain tumor or even several sclerosis. Frequently an electrical stimulation and measurement of nerve response in an affected limb known as an EMG (electromyogram) is carried out to rule out nearby nerve injury as an additional trigger.

If every thing points to Parkinson’s the patient is given a trial of a drug that either replaces or mimics dopamine. if the patient shows improvement then everybody could be fairly particular it is Parkinson’s

The point is that there’s no single protocol or textbook pathway to generating the diagnosis. although the neurologist follows a formal structure to cover all of the so-called bases, the specifics of that path extremely depend upon the findings along the way, which guide every next step inside that structure.

Early Parkinson’s could be tough to diagnose simply because it presents differently in each and every patient, and frequently with symptoms that will effortlessly be dismissed as minor like a little persistent twitching, sleepiness, a minor tremor, as well as depression or anxiety attacks.

A typical story everybody has either experienced or heard of is that 1 or two of the ten typical early warning symptoms (Component 1) show up and on that initial go to to a neurologist the twitching pinky finger (in Michael J. Fox’s case) or in my own, new-onset depression, either get dismissed or symptomatically treated. I was given an antidepressant and when a tremor developed it was dismissed as a side impact of the antidepressant. It was not until I was totally unable to play piano and had inordinate difficulty writing, both from severe slowing in my correct hand, that I was then totally worked up.

In either case, mine or mr. Fox’s, nobody created a mistake or missed anything essential. It is just that for example any 1 or two of the ten warning signs could be interpreted as because of other causes, and generally is.

Review of early symptoms:

Tremor or shaking higher on 1 side

Trouble/stiffness in moving or walking

Soft or Low Voice

Loss of facial expression, “masked facies”

Dizziness and fainting

Stooping or hunching over

I’ve added two much more to this list:

EDS (excessive daytime sleepiness) or fatigue

New-onset psychiatric disorder (generally depression or anxiety attacks)

As soon as PD is suspected, a host of other illnesses and conditions have to be regarded as and ruled out. that is where the so known as “differential diagnosis” list comes in. Every differential list is slightly various depending on what the patient presents to the neurologist and in admiration to neurology as a specialty, these lists can initially be very big. Ruling out all of the other causes on the list prior to PD reaches the top demands a solid working information of every list item and how it’s diagnosed.

Other lab tests and scans are utilized to rule out other causes but ultimately, Parkinson’s Disease is really a clinical diagnosis with probably the most important “test” becoming that initial old-fashioned face to face discussion with, and physical exam by a seasoned neurologist.

A 42 year old woman, a cello player within the nearby symphony, presents to the neurologist complaining of tremor in her correct hand and difficulty manipulating the bow whilst playing. Sadly she has been politely asked to “take a break” from her job with the symphony until she gets adequately evaluated. She has also turn out to be very depressed over the incident. She says the tremor really goes away when she’s playing however it feels like the bow is “caught on something” and so she can’t sweep it across the strings as swiftly.

Here’s a sample beginning differential diagnosis for somebody presenting having a persistent tremor of the proper hand. Even though the reality that the tremor occurs at rest and goes away with movement, and particularly combined with the reality that it occurs only on the proper side elevates PD to #1 on the list.

Sample differential diagnosis list for Parkinson’s (keep in mind that the neurologist should have extensive working information of how every of these presents):

Parkinson’s Disease

Important tremor (a nonspecific tremor of unknown trigger and which doesn’t get worse)

Brain Tumor: she will need to have a CT scan or MRI scan of the brain

Harm to the nerves within the arm within the affected side by trauma or several sclerosis(MS). She will likely undergo EMG nerve evaluation of the proper arm.

Other degenerative neurologic illnesses, a lengthy sub-list, details of which I shall skip:

Benign familial tremor

Dominant SCA (Spinal Cerebellar ataxia)

Olivopontocerebellar degeneration

Familial Basal ganglion calcification (Fahr’s syndrome)

Alzheimer’s syndrome

Amyotrophic lateral sclerosis

Dementia, Lewy-body kind

Parkinsonism-dementia complicated

Progressive supranuclear palsy

Cerebellar degeneration, subacute

Striatonigral degeneration

Corticobasal Degeneration syndromes

Frontotemporal dementia

Lesions of the basal ganglia where the brain controls movement by stroke/hemorrhage

Drugs (her main physician put her on nortriptyline for depression)

Antipsychotic medications

MPTP (a byproduct of poor practices in generating Ecstasy that will induce a parkinson’s like syndrome following a single dose)

Alcohol or narcotic withdrawal

Alcoholic brain degeneration

Following performing a directed interview and examination, her neurologist utilized his own fund of information and expertise, and did not believe she showed functions of any of the other degenerative illnesses listed.

On physical exam and observation he noticed that she would swing her correct arm much less when walking down the hallway. She even slightly dragged her correct foot.

He had her copy some sentences out of a medical text. It took her a lengthy time and also the writing was extremely little.

When he held her arm and moved it at the wrist and elbow he could really feel a ratcheting instead of smooth passive movement (recognized as “cogwheeling”, a classic PD sign).

She denied any drug history and rarely consumes alcohol.

She’s from San Diego where Lyme-carrying deer ticks do not flourish.

An MRI scan of her brain was regular so there is no brain tumor or evidence or stroke/hemorrhage, and no defects suggestive of MS. Parkinson’s usually yields a extremely regular brain scan. Some study methods that use radioactive dopamine-like compounds can reveal a defect nevertheless they’re not usually obtainable, and unnecessary as we see here that the diagnosis could be adequately created with out it.

Her EMG nerve exam showed regular nerve function within the affected arm.

Lastly, and very essential in establishing Parkinson’s as her diagnosis, he placed her on a drug that mimics dopamine and examined her a week later. She showed nearly none of the previous findings on that second go to following a week on the drug.

At that point the neurologist was particular it was PD and gently broke the news to her.

Migraine and Brain Cancer: Diagnosis with Precise Examination of Symptoms

From a layman’s perspective, migraine symptoms may not be much different from brain cancer symptoms, thus accurately diagnosing illnesses is very important.however, the task becomes extremely delicate as the cases of misdiagnosis remain high. Proper diagnosis is a significant part of disease management, and it has to be handled properly since there are a lot of diseases with similar clinical symptoms. thus, assessment and confirmation of a particular disease is normally done based on distinct symptoms and confirmatory clinical and lab test. This is necessary particularly for patients with clinical conditions which have apparently similar symptoms of other diseases.

The errors in diagnosis of the medical condition can result in a wrong belief of well being or may even lead to adopting an unnecessary medical solution. thus consultation with experienced medical practitioners is essential when a dangerous medical condition is suspected. That’s where differential diagnosis is applied. It is a process to determine and differentiate the symptoms by distinctive identification to accurately pinpoint the medical condition.

Common migraine shows symptoms and conditions that are similar to brain tumor. Common mutual symptoms of different conditions calls for differential diagnosis to be used in determining the medical condition.Comparing migraine symptoms and brain tumor symptoms is not a sufficient basis in making definitive diagnosis. There are similar brain cancer symptoms and migraine symptoms, and clinical symptoms are not enough to conclude that a person is suffering from an ordinary migraine and not from brain cancer.

The common denominator of migraine and brain cancer is that they both affect the neurological system. since both conditions affect the brain, it is highly important to give them proper attention and medication. the coinciding symptoms of cancer and migraine range from vomiting, headache, nausea, changes in behavior to vision impairment. If you are experiencing the aforementioned symptoms, then you might be suffering from brain tumor or migraine. It is very important for you to know the differences of such conditions in order for you to know how to properly manage the medical condition.

Migraine is a common medical condition that affects many people and is characterized by severe headache, caused by the enlargement of the temporal artery located outside the cranium beneath the skin temple. This medical condition also sets off with an upsetting serotonergic portion of the control system.

While brain tumor can be pleasant or destructive to the brain. Its the tumor with malevolent growth which is destructive, needs to be treated straightaway and if neglected it could become a life threatening disease.Tumors are malign growth of abnormal cells. As it enlarges, it envelops surrounding tissue; thus, resulting to various symptoms.

Unlike brain tumors, migraines may not pose serious threats to person’s health. in worst cases, migraine may only affect a person to the extent that it impinges on his normal daily activities. Migraine is not fatal, and it is only characterized by throbbing pain on one or both sides of the head. While cancerous brain tumor are very dangerous and could be fatal. in either case, Its highly recommended to seek medical assistance immediately.

Simple observance of medical conditions and symptoms to distinguish between migraine and brain tumor symptoms is not very effective. and differential diagnosis is the only appropriate procedure available for diagnosing and treatment of this condition. Additional probing is necessary and examinations are essential for precisely determining the inherent reasons of medical conditions a patient is suffering from.

Press Release Source: SI-BONE, inc. on Monday December 6, 2010, 4:05 pm EST

SAN JOSE, Calif., Dec. 6, 2010 /PRNewswire/ — SI-BONE, inc. (San Jose, California), a medical device company that is pioneering the use of a minimally invasive surgical (MIS) device to treat the sacroiliac (SI) joint announced today that Ralph F. Rashbaum, MD, Texas Back Institute, has joined its Medical Advisory Board (MAB). Dr. Rashbaum joins noted spine surgeons Steve Garfin, Frank Phillips, Paul Anderson and Nick Shamie, along with SI-BONE founder, mark Reiley, on the SI-BONE MAB.

“The SI joint is a significant cause of low back complaints, including pain and disability,” said Ralph Rashbaum, M.D.  “My experience and published clinical research strongly suggest that the SI joint is a significant contributor to low back problems.  All spine surgeons should include the SI joint as part of their patient work-up and differential diagnosis of low back complaints. the SI joint should perhaps be one of the first things that surgeons evaluate in patients presenting with low back complaints, and I hope that my work with SI-BONE will help teach and convince many other surgeons the importance of this diagnostic thinking.”

Dr. Rashbaum is a board-certified orthopaedic surgeon with a specialization in spine surgery and co-founder of the Texas Back Institute in Plano, Texas, which is one of the largest spine specialty clinics and spine surgical training schools in the United States.  He has significant expertise in diagnosing and treating challenging chronic low back pain patients, many of whom were failed surgery patients, as well as pain mechanisms and the physiological effect of various treatments.  Dr. Rashbaum has published numerous articles and book chapters on these topics and devotes time to training others in the evaluation of chronic low back pain patients.  After earning his Doctor of Medicine from Chicago Medical School, Dr. Rashbaum completed a spine fellowship with Drs. Richard Rothman and Frederick Simone at Pennsylvania Hospital in Philadelphia. He later co-founded Texas Back Institute in 1977.

Commenting on Dr. Rashbaum’s appointment, Jeff Dunn, President and CEO, said, “Having Dr. Rashbaum as a member of our Medical Advisory Board significantly boosts SI-BONE’s capability in getting the word out on appropriate diagnosis of low back complaints that include the SI joint.  In addition, his work with minimally invasive surgical technologies provides us with a unique opportunity to teach many new spine surgeons about the iFuse Implant System™ for SI joint fixation/fusion.”

SI-BONE received clearance in November 2008 from the Food and Drug Administration (FDA) to market its iFuse Implant system. the CE mark for European commercialization was obtained in November 2010. the iFuse provides immediate post-operative fixation, accomplishing the goal of traditional open SI joint fusion through an MIS approach. Clinical publications have identified the SI joint as a pain generator for up to 22 percent of low back pain patients and that up to 75 percent of post-lumbar fusion patients develop SI joint degeneration within five years of surgery. these represent significant unmet clinical needs where iFuse may provide an MIS option.

In response to increasing awareness of SI joint disruption and dysfunction as debilitating symptom generators, SI-BONE, inc. developed an innovative, patented, intramedullary implant to treat the SI joint. the company is also embarking on a post-market multicenter study to determine its effect over time on SI joint pathology and on symptoms associated with SI joint problems.

The iFuse Implant system is a commercially available device in the United States intended for fracture fixation of large bones and large bone fragments of the pelvis for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. the iFuse procedure uses a minimal incision for delivery and implantation of small, titanium implants.  The implants are coated with a porous plasma spray that acts as an interference surface, designed to help decrease implant motion.  These implants have substantial thickness and sophisticated metallurgy and are able to produce a much stronger construct than that of conventional pins or screws used to surgically fix boney structures.  This implant technology from SI-BONE has been previously used successfully in well over 1,000 cases of dysfunctional foot joints.

About SI-BONE, inc.

SI-BONE, inc. (San Jose, California) is a leading spinal medical device company dedicated to the development of tools and products for diagnosing and treating patients with low back issues related to sacroiliac (SI) joint pathology.  The company has developed, and is manufacturing and marketing, less invasive approaches using implants for the treatment of SI joint pathology.  SI-BONE has an experienced management team with extensive experience in orthopedic and spine medical devices.
