In vitro fertilization, or IVF, is the most common and effective type of assisted reproductive technology to help women become pregnant. It involves fertilizing an egg outside the body, in a laboratory dish, and then implanting it in a woman's uterus. By 2016, some 6.5 million babies had been born using in-vitro fertilization (IVF). According to the Centers for Disease Control and Prevention (CDC), around 1.6 percent of babies born in the United States each year are conceived through assisted reproductive technology (ART).
Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.
An intrauterine device (IUD), also known as intrauterine contraceptive device (IUCD or ICD) or coil, is a small, often T-shaped birth control device that is inserted into a woman's uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control (LARC).
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.
Gunshot wounds have become increasing common in urban cities and many such cases can lead to undesirable outcomes. While gunshot wounds to the head are considered most lethal, gunshot wounds to the chest too may be dangerous. Gunshot wound to the chest is challenging owing to the presence of vital organs like lungs, heart and their surrounding structures including major blood vessels. Gunshot wound is caused by penetration of the bullet, which travels through a projectile path after being shot from a firearm. The bullet, on hitting the chest, punctures the tissue it first encounters with, the bones or the muscular chest wall. The extent and severity of the injury depends on the characteristics of the bullet and the firearm, the position and the distance of the victim, the projectile path and the nature of the tissue penetrated.
Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.
Nystagmus is a condition of involuntary (or voluntary, in rare cases) eye movement, acquired in infancy or later in life, that may result in reduced or limited vision. Due to the involuntary movement of the eye, it has been called "dancing eyes"
An abdominal hysterectomy is a surgical procedure that removes your uterus through an incision in your lower abdomen. Your uterus — or womb — is where a baby grows if you're pregnant. A partial hysterectomy removes just the uterus, leaving the cervix intact. A total hysterectomy removes the uterus and the cervix. Sometimes a hysterectomy includes removal of one or both ovaries and fallopian tubes, a procedure called a total hysterectomy with salpingo-oophorectomy (sal-ping-go-o-of-uh-REK-tuh-me). A hysterectomy can also be performed through an incision in the vagina (vaginal hysterectomy) or by a laparoscopic or robotic surgical approach — which uses long, thin instruments passed through small abdominal incisions.
The word enuresis is derived from a Greek word (enourein) that means “to void urine.” It can occur either during the day or at night (though some restrict the term to bedwetting that occurs at night). Enuresis can be divided into primary and secondary forms.

A small spontaneous pneumothorax may resolve without treatment; a pneumothorax arising as a result of lung disease or injury requires immediate treatment. Treatment may include insertion of a chest tube or aspiration of the free air in the chest cavity.Feb 19, 2016
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum). It's also sometimes referred to as an upper gastrointestinal endoscopy. The endoscope has a light and a camera at one end.
