Curare grows as a large liana, or vine, found in the canopy of the South American rainforest. The vine may get as thick as 4 inches in diameter at its base. It has large alternate, heart-shaped leaves which may be 4-8 inches long and almost as wide, with a 2-6 inches long petiole. The leaves are smooth on top with a hairy white bottom, and deeply indented veins radiating from the leaf base. Clusters of small (1/16-1/8 inches), greenish-white flowers are made up of separate male and female flowers. The fleshy fruits are oval, narrow at the base, and approximately 1-2 mm long.

Edible Uses:

The fruit of this vine is edible with a bitter-sweet taste.
Some Indians of South America crush and cook the roots and stems, and add other plants and venomous animals, mixing it until it becomes a light syrup. They call this mixture “ampi”, or “curaré”, which they use on the tip of their arrows and darts to hunt wild game. Crude curare is a dark brown or black mass with a sticky to hard consistency and an aromatic, tarry odor. The name comes from Indian word meaning “poison.”

Curare, in large doses, paralyses the motor nerve-endings in striped muscle, and death occurs from respiratory failure. Curare is very bitter, and is actually a common name for various dart poisons originating from South America.

The young flowers and new growth are added to soups and other food preparations as a soporific vegetables.

Curare has differing effects depending upon dosage, whether it is injected into muscle tissue, or ingested. Curare is used internally in tribal medicine for edema, fever, kidney stones and testicular inflammation. It is also known to relax muscles into a state of inactivity.

Under appropriate medical care and attention, curare is also used to relieve spastic paralysis, to treat some mental disorders, and to induce muscle relaxation for setting fractures. Curare is now used extensively in modern medicine. It is only toxic if it enters the bloodstream. Curare is not for sale to the general public.

As with many Amazonian tribal plant history and legend, curare is prepared by old women. In some traditions, the witch doctor has a monopoly of the business, but generally, wise old men get together to brew a batch. Extra curare was usually carried by tribal members in a gourd or calabash, and stored with weapons.

Medicinal Uses:
The active ingredient in “curaré”, D-tubocurarine, is used in medicine. Brazilians consider the root a diuretic, and use it internally in small quantities for madness and dropsy, and externally for bruises. It is also used for edema, fever, and kidney stones.

Curare is an alkaloid, and acts as a neuromuscular blocking agent to produce paralysis in muscles. It first affects the muscles of the toes, ears, and eyes, then those of the neck, arms and legs, and finally, those involved in breathing. In fatal doses, death is caused by respiratory paralysis. Curare must get into the blood system for it to work. It doesn’t hurt to eat something killed by a poisoned curare arrow, for instance.

The therapeutical employment of curare has been suggested in certain severe and obstinate spasmodic affections, as in epilepsy, chorea, hydrophobia, and, more particularly, in tetanus. It is used by subcutaneous injections of its filtered aqueous solution, thus: Add curare 1 grain, to distilled water 24 minims; dissolve, let the solution stand 48 hours, and filter; of this, from 2 minims (1/12 grain) to 6 minims (1/4 grain) may be used at one injection, carefully repeating the injections until relaxation of the muscles has been effected. Curarine, dissolved in water, with a few drops of sulphuric acid added, to facilitate its solution, is to be used in still smaller doses—from the 1/240 to the 1/120 part of a grain. It is doubtful whether this agent will ever come into general use as a medicinal remedy; at least, not so long as other medicines are known in which greater confidence can be placed. The diversity of action, attributable, in some instances, to its difference of composition, in others to its inertness, or to its highly active qualities, render it an uncertain, as well as an unsafe, remedy.

It is used in modern medicine primarily as an auxiliary in general anesthesia, frequently with cyclopropane, especially in abdominal surgery. Upon injection, curare acts as a neuromuscular blocking agent to produce flaccidity in striated (striped) muscle (it competes with acetylcholine at the nerve ending, preventing nerve impulses from activating skeletal, or voluntary, muscles). It first affects the muscles of the toes, ears, and eyes, then those of the neck and limbs, and, finally, those involved in respiration. In fatal doses, death is caused by respiratory paralysis.
Practitioners commonly rely on velvet leaf as an excellent natural remedy for menstrual difficulties, including cramping and pain, premenstrual syndrome (PMS), excessive bleeding, and fibroid tumors. Its ability to curb excessive menstrual bleeding very quickly can be quite remarkable. It is often employed in overall female balancing formulas, in kidney formulas (for its diuretic and smooth-muscle relaxant effects), and, in combination with other plants, in heart tonics and hypertension remedies. It is also considered effective against malaria, fever, hepatic ailments, gastric ulcers, diabetes, anemia, high cholesterol, cerebral tonic, fever, typhoid, stomach ulcers, pain killer, chronic inflammation of the urinary passages, good diuretic, etc. In North American herbal medicine, velvet leaf is used for many of the same conditions as in South America as well as for inflammation of the testicles and minor kidney problems. Pereira root also acts as an antiseptic to the bladder and is therefore employed for the relief of chronic inflammation of the urinary passages. It is also a good diuretic. The decoction of the stems and roots mixed with wild bee honey is used to treat sterile women. Root decoction used for post-menstrual hemorrhages, the alcoholic maceration, for rheumatism. Macerated leaves, bark and root, mixed with rum, are used by as aphrodisiac. Root decoction used as a cardio tonic, anti-anemic, anti-malarial. One tribe use a leaf decoction for fever and another use the decoction of the bark and stem as a dental analgesic. Some Ecuadorian tribes use the leaf decoction for conjunctivitis and snakebite. Others use the root tea for difficult delivery and nervous or weak children with colic. Also used in homeopathy, in the form of a mother tincture.

Abutua is a very useful herb for women’s affections. Its antispasmodic action makes it influential in treating cramps, painful menstruation and pre and post-natal pain. Brazilian Indian women have for centuries valued its analgesic powers, and the satchels of almost all midwives contain the root of this plant. Helpful for menstrual cramps and difficult menstruation, pre- and post-natal pain Aids poor digestion, drowsiness after meals and constipation.

Intravenous Pyelogram (IVP)

[amazon_link asins=’B00GNOT5YE,0000094676,B016OI52R2,B00CLOG2FU’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’3fb953ae-04fc-11e8-93e5-c5f454fadfcf’]

Definition:
An intravenous pyelogram (IVP) is an x-ray examination of the kidneys, ureters and urinary bladder that uses iodinated contrast material injected into veins.

You may click to see the pictures    :

An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

The dye is injected through an IV (intravenous) line. Since your body clears away the dye by moving all of it into your urine, the organs that make and hold urine show up very brightly on the x-rays. This test is useful for finding kidney stones, tumors, or blockages in the urinary tract.

Why it is done:
An intravenous pyelogram examination helps the physician assess abnormalities in the urinary system, as well as how quickly and efficiently the patient’s system is able to handle waste.

The exam is used to help diagnose symptoms such as blood in the urine or pain in the side or lower back.

The IVP exam can enable the radiologist to detect problems within the urinary tract resulting from:

*kidney stones
*enlarged prostate
*tumors in the kidney, ureters or urinary bladder.

How should you prepare for the test
Your doctor will give you detailed instructions on how to prepare for your IVP study.

You will likely be instructed not to eat or drink after midnight on the night before your exam. You may also be asked to take a mild laxative (in either pill or liquid form) the evening before the procedure.

You should inform your physician of any medications you are taking and if you have any allergies, especially to iodinated contrast materials. Also inform your doctor about recent illnesses or other medical conditions.

On the day before your test, you should drink plenty of fluids. This will help prepare your kidneys for the job of clearing out the dye the next day.

Your doctor will instruct you to eat a special diet the night before the test, so that you have less solid stool in your large intestine. (Large amounts of stool in the intestine can make it harder to interpret your x-rays.) Typical instructions might include using a laxative in the afternoon before your test and limiting your dinner the night before to clear liquids such as broth and juice.

You may be asked to remove some or all of your clothes and to wear a gown during the exam. You may also be asked to remove jewelry, eye glasses and any metal objects or clothing that might interfere with the x-ray images.

Women should always inform their physician or x-ray technologist if there is any possibility that they are pregnant. Many imaging tests are not performed during pregnancy so as not to expose the fetus to radiation. If an x-ray is necessary, precautions will be taken to minimize radiation exposure to the baby. See the Safety page for more information about pregnancy and x-rays.

What does the equipment look like?


The equipment typically used for this examination consists of a radiographic table, an x-ray tube and a television-like monitor that is located in the examining room or in a nearby room. When used for viewing images in real time (called fluoroscopy), the image intensifier (which converts x-rays into a video image) is suspended over a table on which the patient lies. When used for taking still pictures, the image is captured either electronically or on film.

How does the procedure work?
X-rays are a form of radiation like light or radio waves. X-rays pass through most objects, including the body. Once it is carefully aimed at the part of the body being examined, an x-ray machine produces a small burst of radiation that passes through the body, recording an image on photographic film or a special digital image recording plate.

Fluoroscopy uses a continuous x-ray beam to create a sequence of images that are projected onto a fluorescent screen, or television-like monitor. When used with a contrast material, which clearly defines the area being examined by making it appear bright white, this special x-ray technique makes it possible for the physician to view internal organs in motion. Still images are also captured and stored either on film or electronically on a computer.

In the IVP exam, an iodine-containing contrast material is injected through a vein in the arm collects in the kidneys, ureters and bladder, giving these areas a bright white and sharply defined appearance on the x-ray images.

X-ray images are maintained as hard film copy (much like a photographic negative) or, more likely, as a digital image that is stored electronically. These stored images are easily accessible and are sometimes compared to current x-ray images for diagnosis and disease management.

How is the procedure performed?


This examination is usually done on an outpatient basis.

The patient is positioned on the table and still x-ray images are taken. The contrast material is then injected, usually in a vein in the patient’s arm, followed by additional still images.

You must hold very still and may be asked to keep from breathing for a few seconds while the x-ray picture is taken to reduce the possibility of a blurred image. The technologist will walk behind a wall or into the next room to activate the x-ray machine.

As the contrast material is processed by the kidneys a series of images is taken to determine the actual size of the kidneys and to capture the urinary tract in action as it begins to empty. The technologist may apply a compression band around the body to better visualize the urinary structures leading from the kidney.

When the examination is complete, you will be asked to wait until the radiologist determines that all the necessary images have been obtained.

An IVP study is usually completed within an hour. However, because some kidneys empty at a slower rate the exam may last up to four hours.

How you feel:
The IVP is usually a relatively comfortable procedure.

You will feel a minor sting as the contrast material is injected into your arm through a small needle. Some patients experience a flush of warmth, a mild itching sensation and a metallic taste in their mouth as it begins to circulate throughout their body. These common side effects usually disappear within a minute or two and are harmless. Rarely, some patients will experience an allergic reaction. Itching that persists or is accompanied by hives, can be easily treated with medication. In very rare cases, a patient may become short of breath or experience swelling in the throat or other parts of the body. These can be indications of a more serious reaction to the contrast material that should be treated promptly. Tell the radiologist immediately if you experience these symptoms.

During the imaging process, you may be asked to turn from side to side and to hold several different positions to enable the radiologist to capture views from several angles. Near the end of the exam, you may be asked to empty your bladder so that an additional x-ray can be taken of your urinary bladder after it empties.

The contrast material used for IVP studies will not discolor your urine or cause any discomfort when you urinate. If you experience such symptoms after your IVP exam, you should let your doctor know immediately.

Who interprets the results and how to get it
A radiologist, a physician specifically trained to supervise and interpret radiology examinations, will analyze the images and send a signed report to your primary care or referring physician, who will discuss the results with you.

What are the benefits vs. risks?
Benefits:-
*Imaging of the urinary tract with IVP is a minimally invasive procedure.
*IVP images provide valuable, detailed information to assist physicians in diagnosing and treating urinary tract conditions from kidney stones to cancer.
*An IVP can often provide enough information about kidney stones and obstructions to direct treatment with medication and avoid more invasive surgical procedures.
*No radiation remains in a patient’s body after an x-ray examination.
X-rays usually have no side effects in the diagnostic range.


Risks:-

*The dye used in the test can affect your kidneys, and sometimes they do not work as well after exposure to this dye. This effect is almost always temporary, but some people can have permanent damage. There is also a small chance of having an allergic reaction to the x-ray dye used in the test.

*There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis far outweighs the risk.
*The effective radiation dose from this procedure is about 1.6 mSv, which is about the same as the average person receives from background radiation in six months. See the Safety page for more information about radiation dose.
*Contrast materials used in IVP studies can cause adverse allergic reactions in some people, sometimes requiring medical treatment.
*Women should always inform their physician or x-ray technologist if there is any possibility that they are pregnant. See the Safety page for more information about pregnancy and x-rays.

A Word About Minimizing Radiation Exposure
Special care is taken during x-ray examinations to use the lowest radiation dose possible while producing the best images for evaluation. National and international radiology protection councils continually review and update the technique standards used by radiology professionals.

State-of-the-art x-ray systems have tightly controlled x-ray beams with significant filtration and dose control methods to minimize stray or scatter radiation. This ensures that those parts of a patient’s body not being imaged receive minimal radiation exposure.

What are the limitations of IVP studies?
An IVP shows details of the inside of the urinary tract including the kidneys, ureters and bladder. Computed tomography (CT) or magnetic resonance imaging (MRI) may add valuable information about the functioning tissue of the kidneys and surrounding structures nearby the kidneys, ureters and bladder.

IVP studies are not usually indicated for pregnant women.

Bilateral Hydronephrosis

Alternative Names: Hydronephrosis – bilateral

Definition
Bilateral hydronephrosis is the enlargement (distention) of the urine collecting structures and pelvis of both kidneys. Bilateral means both sides.

CLICK & SEE THE PICTURES

Click to See : Unilateral hydronephrosis

Causes
Bilateral hydronephrosis occurs when urine is unable to drain from the kidney down the ureters into the bladder. Hydronephrosis is not itself a disease, but rather a physical result of whatever disease is keeping urine from draining out of the kidneys, ureters, and bladder.

Disorders associated with bilateral hydronephrosis include:
*Acute bilateral obstructive uropathy
*Bladder outlet obstruction
*Chronic bilateral obstructive uropathy
*Neurogenic bladder
*Posterior ureteral valves
*Prune belly syndrome

*Uteropelvic junction obstruction

*Vesicoureteric reflux

Symptoms
Signs of hydronephrosis are generally seen during pregnancy ultrasound studies. There are no symptoms in the fetus.In the newborn, any urinary tract infection is reason to suspect some type of obstructive problem in the kidney. An older child who gets repeat urinary tract infections should be evaluated for possible obstruction.

Urinary tract obstruction usually has no other symptoms beyond an increased number of urinary tract infections.

Diagnosis:

Exams and Tests
Bilateral hydronephrosis may be seen on:

*CT scan of the abdomen or kidneys
*IVP
*Pregnancy (fetal) ultrasound
*Renal scan
*Ultrasound of the abdomen or kidneys

Treatment
Placing a Foley catheter may relieve the obstruction. Other treatment options include draining the bladder or relieving pressure with nephrostomy tubes placed through the skin (percutaneous) or stents placed in the ureters to allow urine to flow from the kidney to the bladder.

Once the blockage is treated, the underlying cause (such as an enlarged prostate) must be identified and treated.

Prognosis:
Advances in fetal ultrasound have given specialists the ability to diagnose problems caused by bilateral obstruction of the urinary tract in the developing fetus. If an obstruction is detected in a fetus, intrauterine surgery (performed while the fetus is still inside the mother’s uterus), or shortly after birth, will improve kidney function.

Newborns diagnosed with obstruction while still in the uterus can receive prompt surgical correction of the defects, often with good results.

Possible Complications :-
Renal insufficiency or failure may develop as a complication of many of the disorders associated with hydronephrosis.

When to Contact a Medical Professional
This disorder is usually discovered by the health care provider.

Prevention
A fetal ultrasound can reveal an obstruction of the urinary tract and allow for early surgery with better outcomes in the newborn. Other causes of obstruction, such as kidney stones, can be diagnosed early if individuals recognize early warning signs of obstruction and kidney disease.

Abdominal Ultrasound

[amazon_link asins=’3131383631,0443069190,0941022463,1588901017,1495108473,0781779782,1583261044,0815141769,1461495989′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’62501c64-5d9f-11e7-93ce-3dae4136a98a’]

Alternative Names:- Ultrasound – abdomen; Abdominal sonogram

Definition :-
Abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs can also be looked at with ultrasound.

.Click to see the pictures

It uses reflected sound waves to produce a picture of the organs and other structures in the upper abdomen. Occasionally a specialized ultrasound is ordered for a detailed evaluation of a specific organ, such as a kidney ultrasound.

An abdominal ultrasound can evaluate the:
*Abdominal aorta, which is the large blood vessel (artery) that passes down the back of the chest and abdomen. The aorta supplies blood to the lower part of the body and the legs.

*Liver, which is a large dome-shaped organ that lies under the rib cage on the right side of the abdomen. The liver produces bile (a substance that helps digest fat), stores sugars, and breaks down many of the body’s waste products.

*Gallbladder, which is a saclike organ beneath the liver. The gallbladder stores bile. When food is eaten, the gallbladder contracts, sending bile into the intestines to help in digesting food and absorbing fat-soluble vitamins.

*Spleen, which is the soft, round organ that helps fight infection and filters old red blood cells. The spleen is located to the left of the stomach, just behind the lower left ribs.

*Pancreas, which is the gland located in the upper abdomen that produces enzymes that help digest food. The digestive enzymes are then released into the intestines. The pancreas also releases insulin into the bloodstream; insulin helps the body utilize sugars for energy.
*Kidneys, which are the pair of bean-shaped organs located behind the upper abdominal cavity. The kidneys remove wastes from the blood and produce urine.

A pelvic ultrasound evaluates the structures and organs in the lower abdominal area (pelvis).

Why It Is Required to be Done:-
The specific reason for the test will depend on your symptoms. Abdominal ultrasound is mostly  done to:

*Determine the cause of abdominal pain.

*Detect, measure, or monitor an aneurysm in the aorta. An aneurysm may cause a large, pulsing lump in the abdomen.

*Evaluate the size, shape, and position of the liver. An ultrasound may be done to evaluate jaundice and other problems of the liver, including liver masses, cirrhosis, fat deposits in the liver (called fatty liver), or abnormal liver function tests.

*Detect gallstones, inflammation of the gallbladder (cholecystitis), or blocked bile ducts. See an illustration of a gallstone.

*Detect kidney stones.

*Determine the size of an enlarged spleen and look for damage or disease.

*Detect problems with the pancreas, such as pancreatitis or pancreatic cancer.

*Determine the cause of blocked urine flow in a kidney. A kidney ultrasound may also be done to determine the size of the kidneys, detect kidney masses, detect fluid surrounding the kidneys, investigate causes for recurring urinary tract infections, or evaluate the condition of transplanted kidneys.

*Determine whether a mass in any of the abdominal organs (such as the liver) is a solid tumor or a simple fluid-filled cyst.

*Determine the condition of the abdominal organs after an accident or abdominal injury and look for blood in the abdominal cavity. However, computed tomography (CT) scanning is more commonly used for this purpose because it is more precise than abdominal ultrasound.

*Guide the placement of a needle or other instrument during a biopsy.

*Detect fluid buildup in the abdominal cavity (ascites). An ultrasound also may be done to guide the needle during a procedure to remove fluid from the abdominal cavity (paracentesis).
How the Test is Performed :-
This test is done by a doctor who specializes in performing and interpreting imaging tests (radiologist) or by an ultrasound technologist (sonographer) who is supervised by a radiologist. It is done in an ultrasound room in a hospital or doctor’s office.

You will need to remove any jewelry that might interfere with the ultrasound scan. You will need to take off all or most of your clothes, depending on which area is examined (you may be allowed to keep on your underwear if it does not interfere with the test). You will be given a cloth or paper covering to use during the test.

An ultrasound machine creates images that allow various organs in the body to be examined. The machine sends out high-frequency sound waves, which reflect off body structures to create a picture. A computer receives these reflected waves and uses them to create a picture. Unlike with x-rays or CT scans, there is no ionizing radiation exposure with this test.

You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the abdomen. This helps with the transmission of the sound waves. A handheld probe called a transducer is then moved over the abdomen.

You may be asked to change position so that the health care provider can examine different areas. You may also be asked to hold your breath for short periods of time during the examination.

Abdominal ultrasound usually takes 30 to 60 minutes. You may be asked to wait until the radiologist has reviewed the information. The radiologist may want to do additional ultrasound views of some areas of your abdomen.

How To Prepare For the Test:-
Tell your doctor if you have had a barium enema or a series of upper GI (gastrointestinal) tests within the past 2 days. Barium that remains in the intestines can interfere with the ultrasound test.

Preparation for the procedure depends on the nature of the problem and your age. Usually patients are asked to not eat or drink for several hours before the examination. Your health care provider will advise you about specific preparation.

For ultrasound of the liver, gallbladder, spleen, and pancreas, you may be asked to eat a fat-free meal on the evening before the test and then to avoid eating for 8 to 12 hours before the test.

For ultrasound of the kidneys, you may not need any special preparation. You may be asked to drink 4 to 6 glasses of liquid (usually juice or water) about an hour before the test to fill your bladder. You may be asked to avoid eating for 8 to 12 hours before the test to avoid gas buildup in the intestines. This could interfere with the evaluation of the kidneys, which lay behind the stomach and intestines.

For ultrasound of the aorta, you may need to avoid eating for 8 to 12 hours before the test.

How It Feels:-
There is little discomfort. The conducting gel may feel slightly cold and wet when it is applied to your stomach unless it is first warmed to body temperature. You will feel light pressure from the transducer as it passes over your abdomen. The ultrasound usually is not uncomfortable. However, if the test is being done to assess damage from a recent injury, the slight pressure of the transducer may be somewhat painful. You will not hear or feel the sound waves.

Risks Factors:
There is no documented risk. No ionizing radiation exposure is involved.

Results:-
An abdominal ultrasound uses reflected sound waves to produce a picture of the organs and other structures in the abdomen.

Abdominal ultrasound  Normal:
The size and shape of the abdominal organs appear normal. The liver, spleen, and pancreas appear normal in size and texture. No abnormal growths are seen. No fluid is found in the abdomen.

The diameter of the aorta is normal and no aneurysms are seen.

The thickness of the gallbladder wall is normal. The size of the bile ducts between the gallbladder and the small intestine is normal. No gallstones are seen.

The kidneys appear as sharply outlined bean-shaped organs. No kidney stones are seen. No blockage to the system draining the kidneys is present.

Abdominal ultrasound Abnormal:
An organ may appear abnormal because of inflammation, infection, or other diseases. An organ may be smaller than normal because of an old injury or past inflammation. An organ may be pushed out of its normal location because of an abnormal growth pressing against it. An abnormal growth (such as a tumor) may be seen in an organ. Fluid in the abdominal cavity (ascites) may be seen.

The aorta is enlarged, or an aneurysm is seen.

The liver may appear abnormal, which may indicate liver disease (such as cirrhosis or cancer).

The walls of the gallbladder may be thickened, or fluid may be present around the gallbladder, which may indicate inflammation. The bile ducts may be enlarged because of blockage (from a gallstone or an abnormal growth in the pancreas). Gallstones may be seen inside the gallbladder.

The kidneys may be enlarged because of urine that is not draining properly through the ureters. Kidney stones are seen within the kidneys (not all stones can be seen with ultrasound).

An area of infection (abscess) or a fluid-filled cyst may appear as a round, hollow structure inside an organ. The spleen may be ruptured (if an injury to the abdomen has occurred).
