This could be caused by an infection, food poisoning, parasites, Crohn's disease, or reduced blood flow in the colon. Hemorrhoids are another common cause of GI or rectal bleeding. A hemorrhoid is an enlarged vein in your rectum or anus. These enlarged veins can rupture and bleed, causing rectal bleeding.
Pancreatic cysts are saclike pockets of fluid on or in your pancreas, a large organ behind the stomach that produces hormones and enzymes that help digest food. Most pancreatic cysts aren't cancerous, and many don't cause symptoms. They're typically found during imaging testing for another problem. Some are actually noncancerous (benign) pockets of fluids lined with scar or inflammatory tissue, not the type of cells found in true cysts (pseudocysts). But some pancreatic cysts can be or can become cancerous. Your doctor might take a sample of the pancreatic cyst fluid to determine if cancer cells are present. Or your doctor might recommend monitoring a cyst over time for changes that indicate cancer.
Fibroadenomas (fy-broe-ad-uh-NO-muhz) are solid, noncancerous breast tumors that occur most often in adolescent girls and women under the age of 30. You might describe a fibroadenoma as firm, smooth, rubbery or hard with a well-defined shape. Usually painless, a fibroadenoma might feel like a marble in your breast, moving easily under your skin when touched. Fibroadenomas vary in size, and they can get bigger or even shrink on their own. Fibroadenomas are among the most common breast lumps in young women. Treatment may include monitoring to detect changes in the size or feel of the fibroadenoma, a biopsy to evaluate the lump, or surgery to remove it.
Rehabilitation time for a meniscus repair is about 3 months. A meniscectomy requires less time for healing — approximately 3 to 4 weeks. Meniscus tears are extremely common knee injuries. With proper diagnosis, treatment, and rehabilitation, patients often return to their pre-injury abilities.
The deep veins play a significant role in propelling blood toward the heart. The one-way valves in deep veins prevent blood from flowing backward, and the muscles surrounding the deep veins compress them, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.
Sialorrhea or excessive drooling is a major issue in children with cerebral palsy and adults with neurodegenerative disorders. In this review, we describe the clinical features, anatomy and physiology of sialorrhea, as well as a review of the world literature on medical treatment using Yale University’s search engine; including but not limited to Medline and Erasmus. Level of drug efficacy is defined according to the guidelines of American Academy of Neurology. Current medical management is unsatisfactory. Topical agents (scopolamine and tropicamide) and oral agents (glyccopyrolate) combined render a level B evidence (probably effective); however, this treatment is associated with troublesome side effects. Double-blind and placebo-controlled studies of botulinum toxin (BoNT) provide a level A evidence for type B (two class I studies; effective and established) and both overall and individual B level of evidence for OnabotulinumtoxinA (A/Ona) and AbobotulinumtoxinA (A/Abo); these are probably effective. For IncobotulinumtoxinA (A/Inco), the level of evidence is U (insufficient) due to lack of blinded studies. Side effects are uncommon; transient and comparable between the two types of toxin. A clinical note at the end of this review comments on fine clinical points. Administration of BoNTs into salivary glands is currently the most effective way of treating sialorrhea.
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.
Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes. They result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders. Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis, and are freely movable and nontender.
A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is displaced — or deviated — making one nasal passage smaller. When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing. The additional exposure of a deviated septum to the drying effect of airflow through the nose may sometimes contribute to crusting or bleeding in certain individuals. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both. Treatment of nasal obstruction may include medications to reduce the swelling or nasal dilators that help open the nasal passages. To correct a deviated septum, surgery is necessary.
Breast lump removal is surgery to remove a lump that may be breast cancer. Tissue around the lump is also removed. This surgery is called a lumpectomy. When a noncancerous tumor such as a fibroadenoma of the breast is removed, it is often called an excisional breast biopsy, instead of a lumpectomy
Ovarian teratoma is a type of germ cell tumour. Germ cell tumours are cancers that begin in egg cells in women or sperm cells in men. There are 2 main types of ovarian teratoma. Mature teratoma, which is benign. Immature teratoma, which is cancerous.
The obstetric examination is distinct from other examinations in that you, the clinician, are trying to assess the health of two individuals – the mother and the fetus – simultaneously. From the initial history, you should be able to judge the health of the pregnancy, any risk factors that need to be addressed, and any concerns from the parents. The history is an opportunity for you to find out how much the parents know about pregnancy, labour and delivery and if they have any preferences to which these events are carried out. A carefully taken history will also direct your attention to specific signs during the examination. As such, it is important that you develop a concise and systematic method of taking the history and carrying out the examination so that you do not miss any important information. This article focuses primarily on the examination. Pregnancy is a sensitive issue, especially for the primigravida’s. Therefore, extra care is needed when you approach a pregnant woman. Always obtain expressed informed consent before examining her and have a chaperone accompany you throughout the examination. A walk-through of what you will be doing is a good way of reassuring the patient and allows the examination to go on smoothly. It is also important to let your patient know that if the examination is too painful, she can stop at any time she wants. Finally, before you begin, you should always wash your hands, especially at an OSCE station.
Thoracentesis is a procedure used to obtain a sample of fluid from the space around the lungs. Normally, only a thin layer of fluid is present in the area between the lungs and chest wall. However, some conditions can cause a large amount of fluid to accumulate. This collection of fluid is called a pleural effusion.
Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain. There are several types of sinusitis, including Acute, which lasts up to 4 weeks Subacute, which lasts 4 to 12 weeks Chronic, which lasts more than 12 weeks and can continue for months or even years Recurrent, with several attacks within a year Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis. Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.
