Pulmonary capillary wedge pressure (PCWP) provides an indirect estimate of left atrial pressure (LAP). Although left ventricular pressure can be directly measured by placing a catheter within the left ventricle, it is not feasible to advance this catheter back into the left atrium. LAP can be measured by placing a special catheter into the right atrium then punching through the interatrial septum; however, for obvious reasons, this is not usually performed because of damage to the septum and potential harm to the patient.

Since the first replant more than 50 years ago, thousands of severed body parts have been reattached, preserving the quality of life for thousands of patients through improved function and appearance that the void remaining after amputation cannot provide. Ronald Malt performed the first replantation on May 23, 1962 at Massachusetts General Hospital on a 12-year-old boy who had his right arm amputated in a train accident. [1, 2] This amputation occurred at the level of the humeral neck.

People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.

Epidural hematoma (EDH) is a traumatic accumulation of blood between the inner table of the skull and the stripped-off dural membrane. EDH results from traumatic head injury, usually with an associated skull fracture and arterial laceration.The inciting event often is a focused blow to the head, such as that produced by a hammer or baseball bat. In 85-95% of patients, this type of trauma results in an overlying fracture of the skull. Blood vessels in close proximity to the fracture are the sources of the hemorrhage in the formation of an epidural hematoma. Because the underlying brain has usually been minimally injured, prognosis is excellent if treated aggressively. Outcome from surgical decompression and repair is related directly to patient's preoperative neurologic condition. [1]

A tonsillolith lodged in the tonsillar crypt. Specialty. Otorhinolaryngology. Tonsilloliths, also known as tonsil stones, are clusters of calcified material that form in the tonsillar crypts, the crevices of the tonsils. While they occur most commonly in the palatine tonsils, they may also occur in the lingual tonsils.

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away. In structural scoliosis, the curve of the spine is rigid and can’t be reversed

Childbirth (also called labour, birth, partus or parturition) is the culmination of a human pregnancy or gestation period with birth of one or more newborn infants from a woman’s uterus. The process of normal human childbirth is categorized in three stages of labour: the shortening and dilation of the cervix, descent and birth of the infant, and birth of the placenta. In some cases, childbirth is achieved through caesarean section, the removal of the neonate through a surgical incision in the abdomen, rather than through vaginal birth
