Ureteroscopy procedure samer kareem 4,040 Views • 2 years ago

A ureteroscopy is an examination or procedure using a ureteroscope. A ureteroscope, like a cystoscope, is an instrument for examining the inside of the urinary tract. The urologist can insert small instruments through the cystoscope to treat problems in the urethra and bladder or perform a biopsy. For a ureteroscopy, the urologist passes the ureteroscope through the bladder and into a ureter.

Ankle fusion (arthrodesis) This is a surgical procedure which joins together the main bones of the ankle joint (the tibia and the talus). However, depending on the technique your surgeon will use, occasionally the fibula will be included in this procedure. The two joint surfaces which generate the pain are removed.

Neurotransmitters are endogenous chemicals which transmit signals from a neuron to a target cell across a synapse. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may also follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation. Neurotransmitters are synthesized from plentiful and simple precursors, such as amino acids, which are readily available from the diet and which require only a small number of biosynthetic steps to convert. The chemical identity of neurotransmitters is often difficult to determine experimentally. For example, it is easy using an electron microscope to recognize vesicles on the presynaptic side of a synapse, but it may not be easy to determine directly what chemical is packed into them. The difficulties led to many historical controversies over whether a given chemical was or was not clearly established as a transmitter. In an effort to give some structure to the arguments, neurochemists worked out a set of experimentally tractable rules. According to the prevailing beliefs of the 1960s, a chemical can be classified as a neurotransmitter if it meets the following conditions: * There are precursors and/or synthesis enzymes located in the presynaptic side of the synapse. * The chemical is present in the presynaptic element. * It is available in sufficient quantity in the presynaptic neuron to affect the postsynaptic neuron; * There are postsynaptic receptors and the chemical is able to bind to them. * A biochemical mechanism for inactivation is present. There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some classification purposes. Major neurotransmitters: * Amino acids: glutamate, aspartate, D-serine, γ-aminobutyric acid (GABA), glycine * Monoamines and other biogenic amines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SE, 5-HT), melatonin * Others: acetylcholine (ACh), adenosine, anandamide, nitric oxide, etc. In addition, over 50 neuroactive peptides have been found, and new ones are discovered regularly. Many of these are "co-released" along with a small-molecule transmitter, but in some cases a peptide is the primary transmitter at a synapse. β-endorphin is a relatively well known example of a peptide neurotransmitter; it engages in highly specific interactions with opioid receptors in the central nervous system. Single ions, such as synaptically released zinc, are also considered neurotransmitters by some[by whom?], as are some gaseous molecules such as nitric oxide (NO) and carbon monoxide (CO). These are not classical neurotransmitters by the strictest definition, however, because although they have all been shown experimentally to be released by presynaptic terminals in an activity-dependent way, they are not packaged into vesicles. By far the most prevalent transmitter is glutamate, which is excitatory at well over 90% of the synapses in the human brain. The next most prevalent is GABA, which is inhibitory at more than 90% of the synapses that do not use glutamate. Even though other transmitters are used in far fewer synapses, they may be very important functionally—the great majority of psychoactive drugs exert their effects by altering the actions of some neurotransmitter systems, often acting through transmitters other than glutamate or GABA. Addictive drugs such as cocaine and amphetamine exert their effects primarily on the dop

Isolated sphenoidal sinusitis
Isolated sphenoidal sinusitis samer kareem 4,971 Views • 2 years ago

Results Sinusitis was characterized as acute in 26 patients, subacute in 5 (including 1 pyocele), and chronic in 8 (including 2 fungal infections). No tumors were found. Isolated sinus cysts were excluded from the study. Headache, the main symptom in 32 patients (82%), was localized most commonly on the vertex. Other common complaints were rhinitis, dizziness, eye symptoms, and fever. In 2 patients, the finding was occult. Eight patients (21%) presented with cranial nerve deficits, and 1 patient had an intracranial complication. Sinus irrigation was performed in 16 patients (41%) and sphenoidotomy was performed in 10 (26%). Fifteen patients (38%) were treated with antibiotic drugs alone. Within 3 months, 31 (84%) of 37 patients had recovered from the illness; 5 still experienced headaches despite having normalized radiographic findings; and 1 had permanent unilateral visual loss. Two patients were lost to follow-up.

Live Rhinoplasty
Live Rhinoplasty samer kareem 93,823 Views • 2 years ago

Rhinoplasty enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. Rhinoplasty surgery can change: Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide, or upturned Nasal asymmetry If you desire a more symmetrical nose, keep in mind that everyone’s face is asymmetric to some degree. Results may not be completely symmetric, although the goal is to create facial balance and correct proportion.
