Laparoscopic surgery for undescended testis
Laparoscopic surgery for undescended testis samer kareem 14,954 Views • 2 years ago

(cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time both testicles are undescended. An undescended testicle is uncommon in general, but common among baby boys born prematurely. The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn't correct itself, surgery can relocate the testicle into the scrotum.

Iron Deficiency Anemia
Iron Deficiency Anemia samer kareem 2,269 Views • 2 years ago

Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues. As the name implies, iron deficiency anemia is due to insufficient iron. Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath. You can usually correct iron deficiency anemia with iron supplementation. Sometimes additional tests or treatments for iron deficiency anemia are necessary, especially if your doctor suspects that you're bleeding internally.

OverviewSymptomsTestingComplicationsTreatmentPreventionTakeawayRead This Next What is gonorrhea? Highlights Some people may never develop noticeable symptoms. Gonorrhea is usually treated with an antibiotic injection or oral antibiotics. You’re at a higher risk of contracting gonorrhea if you’ve had any other STDs. Gonorrhea is a sexually transmitted disease (STD). It’s caused by infection with the bacterium Neisseria gonorrhoeae. It tends to infect warm, moist areas of the body, including the: urethra (the tube that drains urine from the urinary bladder) eyes throat vagina anus female reproductive tract (the fallopian tubes, cervix, and uterus) Gonorrhea passes from person to person through unprotected oral, anal, or vaginal sex. People with numerous sexual partners or those who don’t use a condom are at greatest risk of infection. The best protections against infection are abstinence, monogamy (sex with only one partner), and proper condom usage. Behaviors that make a person more likely to engage in unprotected sex also increase the likelihood of infection. These behaviors include alcohol abuse and illegal drug abuse, particularly intravenous drug use. Advertisement Symptoms of gonorrhea Symptoms

Laser Hair Removal
Laser Hair Removal Scott 24,543 Views • 2 years ago

Utilizing specially engineered lasers, permanent hair removal has never been more comfortable for men and women of all colors and skin types. In just four or five sessions, patients can achieve lasting results without damaging the skin or any surrounding tissue.

Dark pigment (melanin) in the hair shaft and the papilla (the root of the hair follicle) are targeted by a specific light-energy emitted by the laser. In a tiny fraction of a second, the hair is simply vaporized without damaging the skin or any surrounding tissue.

In one pulse (that lasts a tiny fraction of a second) our lasers remove hair on a patch of skin the size of a quarter. The hair removal sensation is like plucking hair or getting snapped by a rubber-band. Our lasers incorporate a patented and state-of-the-art integrated cooling system that acts as a natural anesthetic, cooling down the skin to minimize any discomfort. Patients unanimously report that the hair removal treatment is a "piece of cake" compared to waxing.

Dilation And Curettage Uterus samer kareem 14,671 Views • 2 years ago

Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Doctors perform dilation and curettage to diagnose and treat certain uterine conditions — such as heavy bleeding — or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage — sometimes spelled "dilatation" and curettage — your doctor uses small instruments or a medication to open (dilate) your cervix — the lower, narrow part of your uterus. Your doctor then uses a surgical instrument called a curette to remove uterine tissue. Curettes used in a D&C can be sharp or use suction

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

GIANT UVULA
GIANT UVULA samer kareem 4,926 Views • 2 years ago

Inflammation of the uvula is known as uvulitis. Your uvula will appear red, puffy, and larger than normal. Other symptoms of uvulitis may include: itching burning a sore throat spots on your throat snoring difficulty swallowing trouble breathing If you have a swollen uvula along with a fever or abdominal pain, consult with your doctor right away. In rare cases, the uvula can swell enough to block your airway. Swelling of the throat is a life-threatening event. If this happens, seek immediate medical attention. What causes a swollen uvula? Causes Inflammation is your body’s response when it’s under attack. Triggers for inflammation include: environmental and lifestyle factors an infection trauma genetics Environmental and Lifestyle Factors The most common food allergies are peanuts tree nuts milk eggs wheat soy fish, including shellfish You could be having an allergic reaction to something you touched, swallowed, or breathed in. Some common allergens include: food irritants , such as dust, animal dander, or pollen medication exposure to chemicals or other toxic substances, including tobacco Infection You can get viral infections or bacterial infections. Examples of viral infections include: the common cold the flu mononucleosis chickenpox measles croup The most common bacterial infection is strep throat, which occurs due to Streptococcus pyogenes, which is a type of group A Streptococcus. If you have infected tonsils, or tonsillitis, severe inflammation can cause them to push against and irritate your uvula. Trauma Trauma to the uvula can happen if you need an intubation, such as during surgery. Your uvula can also be injured during a tonsillectomy. This is a procedure to remove your tonsils, which are located on both sides of your uvula. Your throat and uvula can also become irritated if you have acid reflux disease or if you vomit frequently. Genetics A condition called hereditary angioedema (HAE) can cause swelling of the uvula and throat, as well as swelling of the face, hands, and feet. Other symptoms include nausea, vomiting, and abdominal pain. It’s an uncommon genetic mutation that occurs in 1 in 10,000 to 1 in 50,000 people. It’s rare, but there are case reports of individuals who have an elongated uvula, which can also interfere with breathing. What are the risk factors for a swollen uvula? Risk Factors Anyone can get uvulitis, but adults get it less often than children do. You’re at increased risk if you: have allergies use tobacco products are exposed to chemicals and other irritants in the environment have a weakened immune system, making you more susceptible to infections How is a swollen uvula diagnosed? Diagnosis If you have fever or swelling of your throat, see your doctor. Be prepared to give a complete medical history. Tell your doctor: about all the over-the-counter and prescription medications you take if you’re a smoker or you chew tobacco if you’ve recently tried new foods if you’ve been exposed to chemicals or unusual substances about your other symptoms, such as abdominal pain, fever, or dehydration Your doctor may be able to make a diagnosis through a physical exam. It’s likely you’ll also need a throat swab to evaluate for strep or to obtain secretions for culture to determine if you have another bacterial or fungal infection. This test is known as the rapid strep test. You may also need a nasal swab to test for influenza. Blood testing can help identify or rule out some other infectious agents. If those tests are inconclusive, you may need to see an allergist. Blood and skin tests can help identify foods or other substances that cause a reaction. Learn more: Allergy testing » If necessary, imaging tests can provide a more detailed view of your throat and the surrounding area. What’s the treatment for a swollen uvula? Treatment When you have something like the common cold, swelling usually clears up on its own without treatment. Otherwise, treatment will depend on how severe your symptoms are, as well as what’s causing the inflammation. Infection Viral infections tend to clear up without treatment. The only upper respiratory infection for which an antiviral medication is available is influenza. Antibiotics can treat bacterial infections. Even after symptoms clear up, take all the medication as prescribed. If your condition may be contagious, stay home until your doctor tells you that you’re no longer at risk of spreading it to others. Allergy If you test positive for an allergy, try to avoid the allergen in the future. Doctors usually treat allergies with antihistamines or steroids. Anaphylaxis is a severe allergic reaction. Doctors use epinephrine to treat this reaction. Hereditary angioedema Your doctor may treat HAE with any of the following: anabolic steroids, or androgens antifibrinolytics C1 inhibitors, such as C1 esterase inhibitor (Berinert) or C1 esterase inhibitor (recombinant) (Ruconest) a plasma kallikrein inhibitor, such as ecallantide (Kalbitor) bradykinin receptor antagonist, such as icatibant injection (Firazyr) Tell your doctor if you have new or worsening symptoms, and follow up as necessary. Tips for relief home treatment If you have a swollen uvula or sore throat, it’s your body’s way of telling you that something is wrong. A few home remedies can help keep you strong and soothe your irritated throat. Make sure you’re getting enough fluids. If your throat hurts when you drink, try drinking small amounts throughout the day. Your urine should be light in color. If it’s dark yellow or brown, you’re not drinking enough and may be dehydrated. Additional tips include the following: Cool your throat by sucking on ice chips. Frozen juice bars or ice cream may also do the trick. Gargle with warm salt water to ease your dry, scratchy throat. Aim for a full night’s sleep, and nap during the day if you can. What’s the outlook? Outlook A swollen uvula isn’t a common occurrence. Most of the time it clears up without treatment. If you have an infection, prompt treatment should take care of the problem within a week or two. If you have allergies that lead to swelling of the uvula or throat, do your best to avoid that allergen. You should also be prepared to deal with an attack if you come into contact with the substance again. If you’ve ever had anaphylaxis, ask your doctor if you should carry injectable epinephrine (EpiPen) in case of emergency. People with HAE must learn to recognize triggers and early warning signs of an attack. Talk to your doctor about how to manage HAE.
