    1 . meralgia paresthetica ? forearm or leg ?


    Meralgia paraesthetica, or meralgia paresthetica

    and Bernhardt-Roth syndrome is numbness or pain in the outer thigh not caused by injury to the thigh, but by injury to a nerve that extends from the thigh to the spinal column.

    Able to create acute and disabling pain, it's sometimes referred to as "jeans disease", because sufferers are frequently females who wear hip hugger pants.

    This chronic neurological disorder involves a single peripheral nerve, namely the Lateral cutaneous nerve of thigh (also called the Lateral femoral cutaneous nerve). The term meralgia paraesthetica comprises four Greek roots, which together denote "thigh pain involving anomalous perception."

    Cause and presentation

    This lesion is usually unilateral and affects several structures in the midbrain including:
    Structure damaged Effect
    substantia nigra contralateral parkinsonism because its dopaminergic projections to the basal ganglia innervate the contralateral hemisphere motor field
    corticospinal fibers contralateral hemiparesis and typical upper motor neuron findings
    corticobulbar tract difficulty with contralateral lower facial muscles and hypoglossal nerve functions
    oculomotor nerve fibers ipsilateral oculomotor nerve palsy with a drooping eyelid and fixed wide pupil pointed down and out. The oculomotor damage will likely lead to diplopia


    Human brainstem blood supply description. Posterior cerebral artery is #6, and midbrain is behind it.
    It is caused by midbrain infarction as a result of occlusion of the paramedian branches of the posterior cerebral artery or of basilar bifurcation perforating arteries.
    Weber's Syndrome has presented as a manifestation of decompression illness in a recreational scuba diver.

    In order of volume, Earth's most abundant greenhouse gases are:

    * water vapor
    * carbon dioxide
    * methane
    * nitrous oxide
    * ozone
    * CFCs

    By their percentage contribution to the greenhouse effect[12] the four major gases are:

    * water vapor, 36–70%
    * carbon dioxide, 9–26%
    * methane, 4–9%
    * ozone, 3–7%

    The major non-gas contributor to the Earth's greenhouse effect, clouds, also absorb and emit infrared radiation and thus have an effect on radiative properties of the atmosphere.

    In addition to the main greenhouse gases listed above, other greenhouse gases include sulfur hexafluoride, hydrofluorocarbons and perfluorocarbons (see IPCC list of greenhouse gases). Some greenhouse gases are not often listed. For example, nitrogen trifluoride has a high global warming potential (GWP) but is only present in very small quantities.[9]
    Atmospheric absorption and scattering at different electromagnetic wavelengths. The largest absorption band of carbon dioxide is in the infrared.

    Scientists who have elaborated on Arrhenius's theory of global warming are concerned that increasing concentrations of greenhouse gases in the atmosphere are causing an unprecedented rise in global temperatures, with potentially harmful consequences for the environment and human health.[10] Although contributing to many other physical and chemical reactions, the major atmospheric constituents, nitrogen (N2), oxygen (O2), and argon (Ar), are not greenhouse gases. This is because molecules containing two atoms of the same element such as N2 and O2 and monatomic molecules such as Ar have no net change in their dipole moment when they vibrate and hence are almost totally unaffected by infrared light. Although molecules containing two atoms of different elements such as carbon monoxide (CO) or hydrogen chloride (HCl) absorb IR, these molecules are short-lived in the atmosphere owing to their reactivity and solubility. As a consequence they do not contribute significantly to the greenhouse effect and are not often included when discussing greenhouse gases

    oxygen toxicity q
    ans.free radicals

    ref: OXYGEN TOXICITY

    Too little oxygen is obviously incompatible with life. Too much oxygen likewise is not tolerated well. With the increasing popularity of oxygen enriched gas mixtures for both recreational and commercial diving, oxygen toxicity is becoming more common. The body's systems can be overwhelmed by the production of free radicals. The pulmonary and central nervous systems are most readily affected.

    Pulmonary toxicity typically takes more time to develop than could be expected during a dive. The fibrosis that occurs in the lungs develops slowly and, at least at first, is reversible. It does not cause acute incapacitation, but gradual loss of vital capacity, lung compliance, and oxygen diffusion. At one atmosphere of oxygen, symptoms can appear after as little as four hours of exposure.
