Assessment of Automobiles and Pedestrians Control Techniques Within Markets in Kaduna State, Nigeria

The Assessment of automobile and pedestrian control techniques within the market environment cannot be overemphasized as it is one of the most important ways in curtailing poor market environment in terms of traffic congestion. Automobile and pedestrian congestion is a situation that arises when the road networks are incapable of accommodating the traffic generated. Automobile and pedestrians control techniques in market refers to regulation, adoption, or maintenance of automobile and pedestrian functions or feature either by design or new construction within the market. The sustainable design encompasses standard layout, adequate parking, standard road network system, provision of signs and markings, proper zoning etc. This research aimed at assessing pedestrian and automobile control technique adopted within markets in Kaduna with the view of designing a more improved circulation pattern and sustainable markets in terms of automobile and pedestrian control within the study area. With this regard, an observation method of research was adopted. The daily markets were randomly selected out of the numerous markets within Kaduna metropolis and its environs. The result shows that the proper automobiles and pedestrians control techniques was not properly observed or  adopted in over 90% of the market. The study further revealed that the selected markets within Kaduna share similar features and characteristics. Therefore to curtail these, recommendations were made on various practical methods for integration/adoption in market design so as to archive an effective automobile control within the markets in Kaduna metropolis.

Pain patterns and descriptions in patients with radicular pain: Does the pain necessarily follow a specific dermatome?

<p>Abstract</p> <p>Background</p> <p>It is commonly stated that nerve root pain should be expected to follow a specific dermatome and that this information is useful to make the diagnosis of radiculopathy. There is little evidence in the literature that confirms or denies this statement. The purpose of this study is to describe and discuss the diagnostic utility of the distribution of pain in patients with cervical and lumbar radicular pain.</p> <p>Methods</p> <p>Pain drawings and descriptions were assessed in consecutive patients diagnosed with cervical or lumbar nerve root pain. These findings were compared with accepted dermatome maps to determine whether they tended to follow along the involved nerve root's dermatome.</p> <p>Results</p> <p>Two hundred twenty-six nerve roots in 169 patients were assessed. Overall, pain related to cervical nerve roots was non-dermatomal in over two-thirds (69.7%) of cases. In the lumbar spine, the pain was non-dermatomal in just under two-thirds (64.1%) of cases. The majority of nerve root levels involved non-dermatomal pain patterns except C4 (60.0% dermatomal) and S1 (64.9% dermatomal). The sensitivity (SE) and specificity (SP) for dermatomal pattern of pain are low for all nerve root levels with the exception of the C4 level (Se 0.60, Sp 0.72) and S1 level (Se 0.65, Sp 0.80), although in the case of the C4 level, the number of subjects was small (n = 5).</p> <p>Conclusion</p> <p>In most cases nerve root pain should not be expected to follow along a specific dermatome, and a dermatomal distribution of pain is not a useful historical factor in the diagnosis of radicular pain. The possible exception to this is the S1 nerve root, in which the pain does commonly follow the S1 dermatome.</p
