Brain port surgery is a minimally invasive surgical technique performed through a specially designed tube about the size of a dime. Using neuronavigation GPS-like guidance, the brain port is inserted into the brain with millimeter accuracy and is used as a channel to guide the surgeon and his/her instruments to various regions of the brain. Colloid cysts, metastatic tumors, and a variety of tumors within the ventricles are often candidates for this approach.
A subdural hematoma (SDH) is a collection of blood below the inner layer of the dura but external to the brain and arachnoid membrane (see the images below). Subdural hematoma is the most common type of traumatic intracranial mass lesion. Subdural hematoma occurs not only in patients with severe head injury but also in patients with less severe head injuries, particularly those who are elderly or who are receiving anticoagulants. Subdural hematoma may also be spontaneous or caused by a procedure, such as a lumbar puncture (see Etiology). Rates of mortality and morbidity can be high, even with the best medical and neurosurgical care (see Prognosis). Subdural hematomas are usually characterized on the basis of their size and location and the amount of time elapsed since the inciting event age (ie, whether they are acute, subacute, or chronic). When the inciting event is unknown, the appearance of the hematoma on neuroimaging studies can help determine when the hematoma occurred. These factors, as well as the neurologic and medical condition of the patient, determine the course of treatment and may also influence the outcome. Generally, acute subdural hematomas are less than 72 hours old and are hyperdense compared with the brain on computed tomography scans. The subacute phase begins 3-7 days after acute injury. Chronic subdural hematomas develop over the course of weeks and are hypodense compared with the brain. However, subdural hematomas may be mixed in nature, such as when acute bleeding has occurred into a chronic subdural hematoma. Presentation varies widely in acute subdural hematoma (see Clinical). Many of these patients are comatose on admission. However, approximately 50% of patients with head injuries who require emergency neurosurgery present with head injuries that are classified as moderate or mild (Glasgow Coma Scale scores 9-13 and 14-15, respectively). Many of these patients harbor intracranial mass lesions. In a large series of patients who developed intracranial hematomas requiring emergent decompression, more than half had lucid intervals and were able to make conversation between the time of their injury and subsequent deterioration. In a more comprehensive review of the literature on the surgical treatment of acute subdural hematomas, lucid intervals were noted in up to 38% of cases. These patients may be more likely to benefit from medical and surgical intervention when instituted in a timely fashion (ie, before further neurological deterioration).
Respiratory syncytial virus (RSV) is a virus that causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. In adults and older, healthy children, the symptoms of respiratory syncytial virus are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort. Infection with respiratory syncytial virus can be severe in some cases, especially in premature babies and infants with underlying health conditions. RSV can also become serious in older adults, adults with heart and lung diseases, or anyone with a very weak immune system (immunocompromised).
Postmenopausal bleeding (PMB) is defined for practical purposes as vaginal bleeding occurring after twelve months of amenorrhoea, in a woman of the age where the menopause can be expected.[1] Hence it does not apply to a young woman, who has had amenorrhoea from anorexia nervosa, or a pregnancy followed by lactation. However, it can apply to younger women following premature ovarian failure or premature menopause. Unscheduled bleeding in women of menopausal age taking hormone replacement therapy (HRT) should be managed in the same way from a practical perspective.[2] 'Unscheduled bleeding' is defined as non-cyclical bleeding still continuing six months after commencing HRT or after six months of amenorrhoea.
Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso. Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles. While it isn't a life-threatening condition, shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications.
A bilateral complete cleft lip, which has been previously treated with nasoalvoelar molding, is repaired with the Millard-Mulliken technique, which employs reconstruction of the orbicularis oris muscle by advancing bilateral muscular segments. This tutorial for medical professionals was developed to supplement learning of a common surgical technique and is not intended to replace formal surgical training. This slideshow is primarily intended for use on tablets or larger screens. Some detail might be lost on mobile screens.
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.
Symptoms Burning stomach pain Feeling of fullness, bloating or belching Fatty food intolerance Heartburn Nausea The most common peptic ulcer symptom is burning stomach pain. Stomach acid makes the pain worse, as does having an empty stomach. The pain can often be relieved by eating certain foods that buffer stomach acid or by taking an acid-reducing medication, but then it may come back. The pain may be worse between meals and at night. Nearly three-quarters of people with peptic ulcers don't have symptoms. Less often, ulcers may cause severe signs or symptoms such as: Vomiting or vomiting blood — which may appear red or black Dark blood in stools, or stools that are black or tarry Trouble breathing Feeling faint Nausea or vomiting Unexplained weight loss Appetite changes
How Does a Bone Heal? All broken bones go through the same healing process. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury. The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone. Diagram of inflammation in a fractured bone Bone production begins when the clotted blood formed by inflammation is replaced with fibrous tissue and cartilage (known as soft callus). As healing progresses, the soft callus is replaced with hard bone (known as hard callus), which is visible on x-rays several weeks after the fracture. Bone remodeling, the final phase of bone healing, goes on for several months. In remodeling, bone continues to form and becomes compact, returning to its original shape. In addition, blood circulation in the area improves. Once adequate bone healing has occurred, weightbearing (such as standing or walking) encourages bone remodeling.
The uterus, or womb, is an important female reproductive organ. It is the place where a baby grows when a women is pregnant. There are different types of uterine cancer. The most common type starts in the endometrium, the lining of the uterus. This type of cancer is sometimes called endometrial cancer. The symptoms of uterine cancer include Unusual vaginal bleeding or discharge Trouble urinating Pelvic pain Pain during intercourse Uterine cancer usually occurs after menopause. Being obese and taking estrogen-alone hormone replacement therapy (also called menopausal hormone therapy) also increase your risk. Treatment varies depending on your overall health, how advanced the cancer is and whether hormones affect its growth. Treatment is usually a hysterectomy, which is surgery to remove the uterus. The ovaries and fallopian tubes are also removed. Other options include hormone therapy and radiation.
For most cancers, researchers are still trying to understand how they are caused. The same is true for lymphoma - doctors do not know what causes it, although it is more likely to occur in certain people.5,7,8 Medical researchers have identified certain risk factors that make lymphoma more likely, although they often do not understand why:5,8 Non-Hodgkin's lymphoma Age - most non-Hodgkin lymphomas are in people 60 years of age and over Sex - there are different rates of different types of non-Hodgkin's lymphoma across the sexes Ethnicity and location - in the US, African-Americans and Asian-Americans are less prone than white Americans, and the disease is more common in developed nations of the world Chemicals and radiation - some chemicals used in agriculture have been linked, as has nuclear radiation exposure Immune deficiency - for example, caused by HIV infection or in organ transplantation Autoimmune disease, in which the immune system attacks the body's own cells Infection - certain viral and bacterial infections increase the risk. The Helicobacter Infection has been implicated, as has the Epstein Barr Virus (the virus that causes glandular fever)13 See the American Cancer Society's page for more detail on risk factors for non-Hodgkin's lymphoma. Hodgkin's lymphoma Infectious mononucleosis - infection with Epstein-Barr virus Age - two specific groups are most affected: typically people in their 20s, and people over the age of 55 years Sex - slightly more common in men Location - most common in the US, Canada and northern Europe; least common in Asia Family - if a sibling has the condition, the risk is slightly higher, and very high if there is an identical twin Affluence - people from higher socioeconomic status are at greater risk HIV infection
The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.
The vagina is the most delicate and sensitive part of every woman’s body. Naturally female vagina appears to be darker compared to the complexion of other parts of the body. Hence, it is every woman’s dream to have a white complexioned vagina just like their body skin. Most of the women feel that using shop every day may keep their vagina clean and help to make it lighter. But reality is just the opposite. Soaps contain harsh chemicals which not only irritate the delicate skin of vagina and make it darker but they also dis-balance the ph level which plays an important role in maintaining the normal texture of the skin. Well, women need not get disappointed as now there are alternatives of harsh soaps in the market. These alternatives are none other than natural creams which are the best solution to have a naturally fair and glowing vagina without any side effects. Mentioned below are some of the best natural products available in the market to whiten vagina naturally.
