How osteoporosis develops samer kareem 13,047 Views • 2 years ago

Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.

Gestational trophoblastic disease
Gestational trophoblastic disease samer kareem 2,299 Views • 2 years ago

What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.

Gastric Sleeve and Lap Band Surgeries samer kareem 5,739 Views • 2 years ago

There are several things to consider when trying to decide between gastric bypass surgery and gastric sleeve surgery. Unlike the laparoscopic adjustable gastric band (Lap Band), these two operations are both permanent, reduce hunger, and lead to the highest percentage of weight loss. To properly compare gastric sleeve surgery to gastric bypass surgery we will examine the following data : Expected weight loss. Speed of weight loss. Time of surgery. Gastric bypass benefits over sleeve. Gastric sleeve benefits over bypass. Risk of complications. Surgeon skill and preference.

Physical Assessment
Physical Assessment samer kareem 19,197 Views • 2 years ago

Physical assessment is taking an educated, systematic look at all aspects of an individual’s health status utilizing knowledge, skills and tools of health history and physical exam. To collect data- information about the client’s health, including physiological, psychological, sociocultural and spiritual aspects To establish actual and potential problems To establish the nurse-client relationship Method: The history is done first, then the physical examination focuses on finding data associated with the history. Health History- obtained through interview and record review. Physical exam- accomplished by tools and techniques ** A complete assessment is not necessarily carried out each time. A comprehensive assessment is part of a health screening examination. On admission, you will do an admission assessment (not necessarily including everything presented here) and document it on the admission form. You will do a daily shift assessment (patient systems review). And, if client has a specific problem, you may assess only that part of the body (focused). Data Collection: Information is organized into objective and subjective data: Subjective: Apparent only to person affected; includes client’s perceptions, feelings, thoughts, and expectations. It cannot be directly observed and can be discovered only asking questions. Objective: Detectable by an observer or can be tested against an acceptable standard; tangible, observable facts; includes observation of client behavior, medical records, lab and diagnostic tests, data collected by physical exam. ** To obtain data for the nursing health history, you must utilize good interview techniques and communications skills. Record accurately. DO NOT ASSUME. D. Frameworks for Health Assessment There are two main frameworks utilized in health assessment: Head to Toe- systematic collection of data starting with the head and working downward. Functional Health Assessment- Gordon’s 11 functional health patterns that address the behaviors a person uses to maintain health. PERSON is the ACC-ADN framework for assessment. It is similar to Gordon's functional health patterns.

Thyroid Clinical Examination
Thyroid Clinical Examination samer kareem 19,323 Views • 2 years ago

The examination consists of three portions: Inspection, Palpation, and Synthesis of data from these techniques In addition to palpating for size, also note the gland texture, mobility, tenderness and the presence of nodules. Inspection Inspection: Anterior Approach The patient should be seated or standing in a comfortable position with the neck in a neutral or slightly extended position. Cross-lighting increases shadows, improving the detection of masses. To enhance visualization of the thyroid, you can: Extending the neck, which stretches overlying tissues Have the patient swallow a sip of water, watching for the upward movement of the thyroid gland. quicktime video 251KB video demo from Return to the Bedside Inspection: Lateral Approach After completing anterior inspection of the thyroid, observe the neck from the side. Estimate the smooth, straight contour from the cricoid cartilage to the suprasternal notch. Measure any prominence beyond this imagined contour, using a ruler placed in the area of prominence. Palpation Note: There is no data comparing palpation using the anterior approach to the posterior approach so examiners should use the approach that they find most comfortable. Palpation: Anterior Approach placement of hands for palpatation of thyroid in anterior approach The patient is examined in the seated or standing position. Attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Use one hand to slightly retract the sternocleidomastoid muscle while using the other to palpate the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland. quicktime video 454KB video demo from Return to the Bedside. Palpation: Posterior Approach placement of hands for palpatation of thyroid in posterior approach The patient is examined in the seated or standing position. Standing behind the patient, attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Move your hands laterally to try to feel under the sternocleidomstoids for the fullness of the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.

Necrotizing Fasciitis
Necrotizing Fasciitis samer kareem 17,530 Views • 2 years ago

Two types of clinically distinct necrotizing fasciitis have been described. The most common form (type II) usually occurs in individuals with no concurrent medical illness. Many patients report a history of laceration, blunt trauma, or a surgical procedure as a predisposing factor. It is typically caused by group A Streptococcus (Streptococcus pyogenes). In contrast, type I is usually seen in patients with underlying diabetes and peripheral vascular disease. It is generally a polymicrobial infection; some commonly isolated organisms include Staphylococcus aureus, Bacteroides tragi/is, Escherichia coli, group A Streptococcus, and Pre vote/fa species. Crepitus is more common if anaerobic organisms, such as Clostridium perfringens or 8 tragi/is, are involved.
