Children with autism often struggle with temper tantrums. A new test could tell parents if their child is autistic in just 10 minutes posed by model A brain scan which diagnoses autism in children in just ten minutes has been developed by scientists. It would enable the condition to be detected at a much earlier stage so youngsters could begin therapy and treatment before they started school. The test, which is almost 95 per cent accurate, uses Magnetic Resonance Imaging MRI scanners to show how well the different parts of the brain communicating. The scans would eventually replace the painstaking series of checks and tests currently carried out by GPs, psychologists and psychiatrists to diagnose the condition. Parents often have to wait several years to find out if their children involving countless trips to hospitals and long waiting lists to see specialists. Around 1 in children suffer from autism – which ranges in its severity – causing them to suffer learning, communication and behavioural problems. Some experts believe as many as , people in Britain have the condition, but half have never been diagnosed. Researchers at Harvard University have designed a test which uses an MRI scan to show how the different parts of the brain interact. Autism sufferers have weaker connections between different parts of the brain, which is why they have problems communicating and learning.

Bonding with your baby with scans throughout your pregnancy There is nothing quite like watching your baby in the womb for the first time. The London Ultrasound Centre provides the opportunity to supplement your two NHS scans and bond with your unborn child. We have packages and special offers available to suit all budgets and the extra scans can bring you peace of mind should you need extra reassurance at any stage.

NHS wraparound scans The NHS typically only offers two scans during pregnancy at around twelve weeks dating scan and twenty weeks anomaly scan. Both scans check the development of the baby and the twenty week scan is usually where the gender of your baby can be revealed, if so desired. At the London Ultrasound Centre we can offer you a complete spectrum of private ultrasound scans throughout your pregnancy. If you chose to have NHS scans we can offer additional private scans to complement the scans that you receive on the NHS.

You might feel that you would like extra scans, as you are a first time mum or you have had complications in the past. We offer early pregnancy scans for those who may want extra reassurance, or for people who perhaps want to announce the news a little bit earlier to mark a special occasion. We can also tell at that early stage whether you are expecting a multiple pregnancy and estimate your due date.

You may want to see your baby again after your NHS 20 week scan.

Underestimation of gestational age by conventional crown-rump length growth curves. Reprinted with permission of American College of Obstetricians and Gynecologists Variations in the measurement of CRL can be attributed to differences in fetal growth patterns. Such differences are related to factors similar to those that influence birth weight curves, including maternal age and parity, prepregnancy maternal weight, geographic location, and population characteristics.

These include incorporation of the yolk sac or lower limbs in the CRL measurement, excessive curling or extension of the fetus, and tangential section of the trunk. The biparietal diameter BPD is one of the most commonly measured parameters in the fetus. Campbell was the first investigator to link fetal BPD to gestational age 20 ; however, since this original report, numerous publications on this subject have appeared in the literature. The BPD is imaged in the transaxial plane of the fetal head at a level depicting thalami in the midline, equidistant from the temporoparietal bones and usually the cavum septum pellucidum anteriorly Fig.

Gestational age assignment is based on the mean BPD; however, a single BPD encompasses a range of ages in which most fetuses of that size are most likely to fall Table 4. A number of factors may contribute to variation or inaccuracy in the BPD measurement.

Dating and viability What is a dating scan? A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Dating scans also reveal other important information such as: Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.

For transvaginal ultrasound you can have an empty bladder When is it recommended?

Tactics: Tactics, in warfare, the art and science of fighting battles on land, on sea, and in the air. It is concerned with the approach to combat; the disposition of troops and other personalities; the use made of various arms, ships, or aircraft; and the execution of movements for attack or defense. This.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening. Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.

This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results. This means that combined first trimester screening will not give us a definitive answer.

Chorionic villus sampling and amniocentesis are invasive tests, involving putting needles into the placenta or amniotic sac, and they are associated with an increased risk of miscarriage. For more information of prenatal diagnostic testing, please go to: The thickness of this fluid can be precisely measured and this is called the nuchal translucency or NT measurement.

Normally the amount of fluid is small, producing a thin NT measurement.

Fundamentals Evolution of the term The word tactics originates in the Greek taxis, meaning order, arrangement, or disposition—including the kind of disposition in which armed formations used to enter and fight battles. From this, the Greek historian Xenophon derived the term tactica, the art of drawing up soldiers in array. Likewise, the Tactica, an early 10th-century handbook said to have been written under the supervision of the Byzantine emperor Leo VI the Wise, dealt with formations as well as weapons and the ways of fighting with them.

The term tactics fell into disuse during the European Middle Ages. Until then, authors had considered fighting to be almost the sum total of war; now, however, it began to be regarded as merely one part of war. The art of fighting itself continued to carry the name tactics, whereas that of making the fight take place under the most favourable circumstances, as well as utilizing it after it had taken place, was given a new name: Since then, the terms tactics and strategy have usually marched together, but over time each has acquired both a prescriptive and a descriptive meaning.

There have also been attempts to distinguish between minor tactics, the art of fighting individuals or small units, and grand tactics, a term coined about by the French military author Jacques-Antoine-Hippolyte de Guibert to describe the conduct of major battles.

Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use. The most common are: The first element to be measurable is the gestation sac of the early pregnancy.

The development of a baby is quite an intricate process. From the moment the egg and sperm meet, your baby is beginning to grow. This early part of development lays the foundation for .

Share Your Story The worry for patients and health care professionals is that any chest pain may originate from the heart. Angina is the term given to pain that occurs because the coronary arteries blood vessels to the heart muscle narrow and decrease the amount of oxygen that can be delivered to the heart itself. This can cause the classic symptoms of chest pressure or tightness with radiation to the arm or jaw associated with shortness of breath and sweating.

Unfortunately, many people don’t present with classic symptoms, and the pain may be difficult to describe — or in some people may not even be present. Instead of angina or typical chest pressure, their anginal equivalent symptom they get instead of chest pain may be indigestion , shortness of breath, weakness , dizzyness, and malaise. Women and the elderly are at higher risk for having an atypical presentation of heart pain.

The narrowing of blood vessels or atherosclerosis is due to plaque buildup. Plaque is a soft amalgam of cholesterol and calcium that forms along the inside lining of the blood vessel and gradually decreases the diameter of the blood vessel and restricts the flow of blood. If the plaque ruptures, it can cause a blood clot to form and completely block the vessel.

The gestational sac is the first identifiable structure routinely imaged in the first trimester. It is identified by transabdominal ultrasound as early as 5 weeks’ gestation and may be seen as early as 4 weeks’ gestation by transvaginal ultrasound. 15, 16, 47 The gestational sac is an echo-free space containing the fluid, embryo, and extraembryonic structures.

Transvaginal ultrasound is performed using a special transducer which is slightly thicker than a tampon. It is covered with a disposable latex sheath and lubricating gel, then gently placed into the vagina. The probe sits in the vagina throughout the examination which usually takes between minutes. Most patients find the examination much more tolerable when compared to a cervical PAP smear. During the scan the sonographer may need to gently press on the abdomen to move bowel out of the way and bring the ovaries and other pelvic structures into view.

This also enables any point of tenderness in the pelvis to be identified. Transvaginal or transabdominal ultrasound: Is there a choice? It is a Sydney Ultrasound For Women protocol to offer transvaginal assessment for all Gynaecological and early pregnancy scans. This is because the transducer is positioned close to the pelvic structures, producing superior image quality, hence, the most detailed and accurate diagnosis. Though a SUFW protocol to offer an internal scan, patients may decline and instead be scanned transabdominally.

In certain circumstances a transvaginal ultrasound examination is not possible or not advisable eg. A full bladder transabdominal ultrasound will then be performed. What are the preparations I should take before the ultrasound examination?
