Electrophysiological Grading of Carpal Tunnel Syndrome
ORIGINAL ARTICLE Electrophysiological Grading of Carpal Tunnel Syndrome MUHAMMAD WAZIR ALI KHAN ABSTRACT Background: Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy caused by a conduction block of distal median nerve at wrist. Women are affected more commonly than men. Clinical signs are quite helpful in diagnosis but electrophysiological tests yield accurate diagnosis and severity grading along with follow-up and management. Aim: To utilize nerve conduction studies (NCS) to diagnose carpal tunnel syndrome and further classify its severity according to the AAEM criteria. Methods: This descriptive study was conducted at the Department of Neurology, Sh. Zayed Medical College/Hospital, Rahim Yar Khan from June 2013 to Dec 2014. Overall, 90 patients and 180 hands were evaluated through nerve conduction studies. Patients with clinically high suspicion of CTS were included for NCS. Clinical grading was done using the AAEM criteria for CTS. Other variables like duration of symptoms, handedness, bilateral disease and gender were noted. Mean and median were calculated for age of the patients. Results: Ninety patients and 126 hands were identified with carpal tunnel syndrome. Most patients (80%) were females with age range from 19 to 75 years. More than one third had bilateral disease. Dominant hand was involved in majority of the patients. Most patients had (42.8%) severe CTS as per AAEM criteria. Also duration of symptoms directly correlated with severity of disease. Conclusion: Nerve conduction study is a valuable tool in accurate diagnosis and grading of carpal tunnel syndrome. Keywords: Phalen sign, Tinel Sign, electrophysiology, median nerve INTRODUCTION 4,5,6 electrophysiological findings, are quite valuable . -
South Palo Alto Tunnel with At-Grade Freight
RAIL FACT SHEETS South Palo Alto Tunnel with At-Grade Freight About the Tunnel with At-Grade Freight For the tunnel alternative, the railroad tracks will be lowered in a trench south of Oregon Expressway to approximately Loma Verde Avenue. The twin bore tunnel will begin near Loma Verde Avenue and extend to just south of Charleston Road. The railroad tracks will then be raised in trench to approximately Ferne Avenue. The new electrified southbound railroad tracks will be built at the same horizontal location as the existing railroad track, however, the northbound track will be moved to the east within the limits of the tunnel to accommodate the spacing required between the twin bores. The railroad tracks in the trench and tunnel will carry only passenger trains. The freight trains will remain at-grade. The roadways at Meadow Drive and Charleston Road remain at their existing grade and will have a similar configuration that exists today with the addition of Class II buffered bike lanes on Charleston Road. This will require expanding the width of the road to maintain bike lanes through the overpass of the railroad. By the numbers Neighborhood Considerations • Diameter of twin bores is 30 feet. • Alma Street will permanently be reduced to one lane • Railroad track is designed for 110 mph. in each direction from south of Oregon Expressway to Ventura Avenue and from Charleston Road to Ferne • Meadow Drive and Charleston Road are Avenue. designed for 25 mph. • The train tracks will be approximately 70 feet below the Proposed Ground Level View - Looking Southwest • Maximum grade on railroad is 2%. -

Unsealed Road Grading Your Questions Answered
Unsealed Road Grading Your Questions Answered What is maintenance grading? Council grades unsealed roads to reshape and re-compact the road, to reduce lumps and bumps and ensure that the road will shed water away from the centre after rain. A grading maintenance schedule is adhered to every 6 or 12 months, depending upon the road condition, the amount of use and the effects of wet weather. What is gravel re-sheeting? Gravel re-sheeting is when new gravel is added to the road. This is due to the severe deterioration of the road that can compromise the safety of road users. The gravel is generally laid in loose layers and then trimmed and compacted using a grader, water cart and roller so that the new road generally has a depth of about 150mm. Why does my road lose gravel? Gravel wears away over time due to the combination of the environment (wetness and dryness), the type and volume of traffic and excessive traffic speed. Softer gravel rock will wear away faster than harder gravel rock. Unsealed roads are made up of a mixture of gravel of differing sizes, clay and soils. This mixture affects the strength of the pavement and how long it will last. The rock gives the pavement strength and the clay and other soils binds the gravel together. Where possible, the grader drivers will recover as much of the loose gravel as they can during the grading of a road and turn it from the edge back into the centre of the road. Why is does my road appear to be shrinking? As the road wears down over time the edges of the road pavement will wear and the width can become less. -

Stallion Synopsis For: Not This Time Prepared By: Alan Porter Prepared For: Taylor Made Stallions

Not only are we able to proven mating advice but we are also able to advise on mare selection, management and promotion of stallions, and selection and purchase of racing and breeding stock. For more information on the services visit www.pedigreeconsultants.com, email [email protected] or call +1 859 285 0431. NOT THIS TIME The most brilliant two-year-old son of sire of sires, Giant’s Causeway, Not This Time was also arguably the fastest and most spectacular two-year-old of his crop. In addition to being by Storm Cat’s leading sire son, he is out of record-breaking graded and multiple stakes winning Miss Macy Sue – also dam of brilliant Breeders’ Cup Mile (gr. I) victor Liam’s Map – and descends from Ta Wee, a two-time Champion Sprinter who is half-sister to the legendary Dr. Fager. Giant’s Causeway has demonstrated an affinity for the Fappiano branch of Mr. Prospector, and Fappiano is particularly interesting here, as he is out of a mare by Dr. Fager, which should work extremely well with remarkable strong Tartan Farm/Genter heritage in the dam of Not This Time (which includes inbreeding to Dr. Fager’s brilliant half-sister, Ta Wee). We can note that Unbridled’s Song – a grandson of Fappiano – is the sire of Not This Time’s brilliant half-brother Liam’s Map.
