Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear in their mid-60s. Estimates vary, but experts suggest that more than 5 million Americans may have Alzheimer’s. Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living. The causes of dementia can vary, depending on the types of brain changes that may be taking place. Other dementias include Lewy body dementia, frontotemporal disorders, and vascular dementia. It is common for people to have mixed dementia—a combination of two or more disorders, at least one of which is dementia. For example, some people have both Alzheimer's disease and vascular dementia. Alzheimer’s disease is named after Dr. Alois Alzheimer. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms included memory loss, language problems, and unpredictable behavior. After she died, he examined her brain and found many abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary, or tau, tangles). These plaques and tangles in the brain are still considered some of the main features of Alzheimer’s disease. Another feature is the loss of connections between nerve cells (neurons) in the brain. Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body.

his patient had spilled boiling water on his lower leg a couple days before. This isn't complicated but the teaching points should focus on draining the large blistered areas and attempting to maintain moisture as long as we can so the skin doesn't contract down on itself.

Amniotomy is the official term for artificially breaking the bag of waters during labor. It is believed that breaking the bag of waters will help to speed up an otherwise slow labor. Amniotomy is part of the Active Management of Labor practiced in some hospitals. Amniotomy is performed by a midwife or doctor. A long, thin instrument with a hook on the end is inserted into the vagina and through the cervix so it can catch and rip the bag of waters. To perform an amniotomy, the cervix must be dilated enough to allow the instrument through the cervix, generally at least a two. Why choose Amniotomy? Unlike other medical methods of starting labor, amniotomy does not add synthetic hormones to your labor. Instead it seems to stimulate your body’s own labor process. Amniotomy allows the use of an internal electronic fetal monitor. How effective is Amniotomy? Amniotomy alone is unpredictable, it may take hours for labor to start with amniotomy. Because amniotomy increases the risk for infection, most caregivers use amniotomy in combination with synthetic oxytocin. Birth does happen faster when amniotomy is combined with synthetic oxytocin than when amniotomy is used alone. Risks of Amniotomy Risks for Mother Increases the risk for infection. This risk is increased with length of time the waters are broken and with vaginal exams. Because of the infection risk, a time limit is given by which the mother must give birth. As the time limit approaches attempts to progress labor will become more aggressive. The fore waters equalize pressure on the cervix so it will open uniformly. When they are broken, the mother increases her chances of having uneven dilation. Risks for Baby Increases the risk of umbilical cord compression. The fore waters equalize pressure on the baby’s head as it presses against the cervix. When they are broken, the pressure on the baby’s head may be uneven causing swelling in some parts.
A testicular examination is mainly performed on male patients who present with testicular pathology e.g. pain, swelling, a lump. Although titled testicular examination it involves the examination of the penis, scrotum and testes. As this is an intimate examination it is pertinent to gain a good rapport with your patient, maintain good communication and ensure the patient’s dignity at all times. Remember to offer a chaperone for this skill. For the purposes of your exam, you will most likely be examining a mannequin.
Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.
Sickle cell anemia is an inherited form of anemia — a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body. Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body. There's no cure for most people with sickle cell anemia. However, treatments can relieve pain and help prevent further problems associated with sickle cell anemia.
Podalic version is an obstetric procedure wherein the fetus is turned within the womb such that one or both feet present through the cervix during childbirth. It is used most often in cases where the fetus lies transversely or in another abnormal position in the womb.
