It is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body’s major arteries and veins in the abdomen, arm, leg, neck and head. There are three types of Doppler ultrasound i.e. color Doppler, power Doppler and spectral Doppler. • Color Doppler uses a computer to convert Doppler measurements into an array of colors to show the direction and speed of blood flow through a blood vessels. • Power Doppler is a sensitive technique then the color technique and it shows more detail about blood flow. It does not helps the radiologists to determine the direction of blood flow which may be important in some situations. • Spectral Doppler shows graphically measurements of blood flow. It can also convert the blood flow information into distinctive sound that can be heard with every …show more content…

The most common method in chromosomal analysis is karyotyping analysis. Karyotyping analysis: Preparation and analysis of chromosomes from cultured amniotic fluid cells or cultured amniotic chorionic villi require at least 2 weeks. The procedure for the karyotyping analysis form aminocenetsis fluid will be take amniotic fluid cells and culture this with media and then harvested them and make slides and then karyotype these slides. The chromosome analysis after ultrasonography is associated with chromosome abnormalities, karyotyping of either amniotic fluid cells or fetal blood cells obtained by cordocenetsis may be performed after ultrasonographic detection of an abnormality. The mostly chromosome abnormalities have been found because of cystic hygroma, limb abnormalities, omphalocele, duodenal stenosis, hydrocephalus and malformations of the face. (thompson, 1986) 3.2.Biochemical Assays for Metabolic Diseases: More than 100 metabolic disorders can be diagnosed prenatally in chorionic villus tissue or cultured amniotic fluid cells, and a few rare conditions can even be identified directly by assay of a substances in amniotic fluid. The metabolic disorders diagnosed by enzyme assay in chorionic villi or cultured amniotic fluid

Introduction The purpose of this lab was to use chemical and physical tests to identify indicators of disease in synthetic urine samples. This lab tested samples for protein levels, glucose levels, and pH levels. In a normally functioning individual, proteins cannot pass through the glomerulus; therefore proteins should not be found in urine. However, in the nephrons of individuals with Bright’s Disease, the glomerulus no longer stops all proteins from entering the urine (Giuseppe et al., 2002, pp.

Monchek and Wiedaseck define Hydatidiform mole as a disease resulting from an atypical growth of the trophoblastic cells that would normally develop into the placenta. It starts at the time of fertilization due to a defective union of the sperm and ovum, which causes an aberrant proliferation of the trophoblastic tissue that rapidly fills the uterine space explains Monchek and Wiedaseck. Monchek and Wiedaseck describe the “mole” as an edematous, grape-like structure formed by the filling of the placental villi with fluid. “The incidence of hydatidiform mole is 1 per 1000 pregnancies” explains Beena, Jose, Teerthanath and Shetty (2016). The importance of this disease is the loss of pregnancy and the possibility of developing choriocarcinoma

Some of the tests for diagnosis during pregnancy include ultrasound, amniocentesis, and an AFP (alfa-fetaprotein) test. An ultrasound is a non-invasive test if done abdominally, and oftentimes spina bifida can be seen as a result of the ultrasound. Amniocentesis is an invasive procedure in which a needle is inserted into the amniotic sac and a sample of amniotic fluid is obtained and tested. If the level of AFP is found to be higher than average, this could be an indication of spina bifida.

There are changes in the T-wave and in the ST segment of the fetal ECG due to a worsening fetal hypoxia. Hence these parameters can be assessed to diagnose a hypoxaemic fetus. A mature fetus exposed to hypoxemia develops an elevated ST segment with a progressive rise in T-wave height that is expressed as T:QRS ratio. An increasing T: QRS ratio indicates fetal cardiac ability to adapt to hypoxia.

The prenatal testing can be done with the Alpha Fetoprotein (AFT) test. This test is performed during the first 15 and 20 weeks of pregnancy (UCSF). Abnormal results may indicate a spinal cord defect, such a Spina Bifida. Another test that is used is the ultrasound (CT) which it is harnmlees, this test uses a high-frequency sound waves that creates images of the fetus. The Amniocentesis test is recommend by doctors for women who have test it for high levels of Alpha Fetoprotein that the ultrasound could not be explained.

22q11.2 Deletion Syndrome 22q11.2 deletion syndrome, also commonly known as DiGeorge syndrome, is a congenital disorder characterised by a wide number of defects, varying in severity. Most notable of these defects include congenital heart disease, palatal deformations and hypocalcaemia due to hypoparathyroidism. Affected individuals often have cognitive or learning difficulties such as ADHD and may suffer from psychiatric disorders in later life, especially schizophrenia. Deficiencies in renal and gastrointestinal function are common, along with feeding issues in babies.

Astronomers use the terms "red shifted" and "blue shifted" to describe how light changes as an object moves closer to or away from an observer. The Doppler effect affects light waves the same way it affects sound waves. As an object in space moves farther away from the observer, the light it gives off is shifted to the red end of the visible light spectrum because its wavelengths are longer due to the doppler effect. If an object moves closer to the observer, the light it gives off is shifted to the blue end of the visible light spectrum because its wavelengths are shorter. Astronomers have been able to use this to measure the expansion of the universe.

Hospital-acquired infection can be referred to as a nosocomial infection. This is an infection that’s contracted from the staff and/or area of the healthcare facility/hospital. The staff can spread infection while dealing with the patient/s, as well as contaminated equipment, sheets from the bed and or air droplets can spread this infection. Sometimes the microorganism originates from the patient 's skin micro biota. Nosocomial pneumonia is a nosocomial bacterial infection that is mostly seen in surgical intensive care units (ICUs).

Regardless of the improvements that have been made there is still a risk of miscarriages as a result. This risk factors can be contributed to the invasiveness of the procedure as well as the time during the pregnancy at which it is performed. The later the genetic testing is performed, the more developed the unborn child is and the later the possible abortion would take place. The two most common forms of testing are ¨amniocentesis or chorionic villus sampling¨ (Rebouché and Rothenberg 989). Both of these tests ¨[require] extracting cells from the fetus in utero, either through the mother 's abdomen or vagina¨ (Rebouché and Rothenberg 989).

The Modalities of Physical Therapy Many people have heard of physical therapists and have a basic understanding of the various methods which the therapist use. They know the therapist will perform stretches with the patient and maybe use another machine to help the rehabilitation process, but do they completely understand the means the physical therapists use? The answer is no. The purpose of this essay is to explain the different modalities physical therapists use to help patients recover from their injuries.
