Acne is a skin disease that involves the oil glands at the base of hair follicles. Acne is not dangerous, but can leave skin scars. Types of pimples include whiteheads, blackheads, papules, pustules, nobules, cysts. ... Treatment for acne may depend on how severe and persistent .
Injuries and certain medical conditions can result in bleeding. This can trigger anxiety and fear, but bleeding has a healing purpose. Still, you need to understand how to treat common bleeding incidents, like cuts and bloody noses, as well as when to seek medical help.
Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency. Vitamin D promotes the absorption of calcium and phosphorus from the gastrointestinal tract. A deficiency of vitamin D makes it difficult to maintain proper calcium and phosphorus levels in bones, which can cause rickets. Adding vitamin D or calcium to the diet generally corrects the bone problems associated with rickets. When rickets are due to another underlying medical problem, your child may need additional medications or other treatment. Some skeletal deformities caused by rickets may require corrective surgery.
Radiosurgery: Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, offer patients a new option for the treatment of lung cancer. The CyberKnife® System is used to treat lung cancer patients who cannot tolerate surgery, have an inoperable tumor, or are seeking an alternative to surgery.
In patients age ;::25, HPV DNA testing is the preferred next step in management if the initial cytology shows ASC-US. In this method, samples are collected for both cytology and reflex HPV DNA. If cytology results are positive, HPV DNA testing is performed. If cytology results are negative, the sample for HPV DNA is discarded. HPV DNA testing along with Pap smear at 3 years is recommended if initial cytology shows ASC-US but HPV DNA testing is negative
Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.
Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.
Giant cell tumour is a locally aggressive primary bone tumour, located eccentrically in the metaphysis and epiphysis of a long bone. It commonly affects distal end of Femur, proximal end of Tibia and distal end of Radius. It is occasionally reported in small bones of hand and foot[1], spine[2] and pelvis[3]. Though it occurs in 20 - 35 year old individuals commonly, it can also be seen in children as young as 2 years[4] and also in older individuals
An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).
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
Caesarean section is the most common way to deliver a breech baby in the USA, Australia, and Great Britain. Like any major surgery, it involves risks. Maternal mortality is increased by a Caesarean section, but still remains a rare complication in the First World. Third World statistics are dramatically different, and mortality is increased significantly. There is remote risk of injury to the mother’s internal organs, injury to the baby, and severe hemorrhage requiring hysterectomy with resultant infertility. More commonly seen are problems with noncatastrophic bleeding, postoperative infection and wound healing problems. It should be added that the increase in maternal mortality rates could be slightly skewed due to the fact that Caesarean sections are often used during high-risk pregnancies and/or when mortality is already a strong possibility.
One large study has confirmed that elective cesarean section has lower risk to the fetus and a slightly increased risk to the mother, than planned vaginal delivery of the breech however elements of the methodology used have undergone some criticism.
The same birth injuries that can occur in vaginal breech birth may rarely occur in Caesarean breech delivery. A Caesarean breech delivery is still a breech delivery. However the soft tissues of the uterus and abdominal wall are more forgiving of breech delivery than the hard bony ring of the pelvis. If a Caesarean is scheduled in advance (rather than waiting for the onset of labor) there is a risk of accidentally delivering the baby too early, so that the baby might have complications of prematurity. The mother’s subsequent pregnancies will be riskier than they would be after a vaginal birth (uterine rupture). The presence of a uterine scar will be a risk factor for any subsequent pregnancies.
Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.
The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen) To discharge sperm within the female reproductive tract during sex To produce and secrete male sex hormones responsible for maintaining the male reproductive system
Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.
The diffuse lung diseases tend to cause infiltrative opacification in the periphery of the lung. As the name of the group of diseases suggests, they are diffuse. While the consolidation or ground-glass change is usually bilateral, it may be localised, e.g. radiation pneumonitis.
A stress fracture typically feels like an aching or burning localized pain somewhere along a bone. Usually, it will hurt to press on it, and the pain will get progressively worse as you run on it, eventually hurting while walking or even when you're not putting any weight on it at all.
Although techniques of vascular anastomosis after trauma are numerous in type and form, most surgeons will default to the one associated with the greatest comfort and ease. This report offers a rapid and reliable repair using a conceptually and operationally simple technique. Its methodology is appropriate for all repairs, including cases mandating the insertion of vascular conduit. We have employed this technique for the past 15 years in nearly all patients with vascular injuries, regardless of the site and size of the vessel. This has included vessels of the neck, torso, upper and lower extremities. There have been no obvious complications associated with its use. Major advantages include: 1) the operating system is always oriented towards the surgeon, 2) the posterior row of sutures is placed as both ends are readily visualized, avoiding the need for potentially obscuring traction stitches, and 3) flushing is easily performed prior to completing the anterior suture row.
