A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness. In 1983 Joao Lobo Antunes, a Portuguese doctor, implanted a bionic eye in a person born blind.
Wound closure techniques have evolved from the earliest development of suturing materials to comprise resources that include synthetic sutures, absorbables, staples, tapes, and adhesive compounds. The engineering of sutures in synthetic material along with standardization of traditional materials (eg, catgut, silk) has made for superior aesthetic results. Similarly, the creation of topical skin adhesives (the monomer 2-octyl cyanoacrylate), surgical staples, and tapes to substitute for sutures has supplemented the armamentarium of wound closure techniques. Aesthetic closure of a wound, whether traumatic or surgically induced, is based on knowledge of healing mechanisms and skin anatomy (see the image below), as well as an appreciation of suture material and closure technique. Choosing the proper materials and wound closure technique ensures optimal healing.[1]
You should not use aspirin if you have a bleeding disorder such as hemophilia, a recent history of stomach or intestinal bleeding, or if you are allergic to an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Relafen, Feldene, and others. Do not give this medication to a child or teenager with a fever, flu symptoms, or chicken pox. Salicylates can cause Reye's syndrome, a serious and sometimes fatal condition in children.
www.lung.org > Lung Health and Diseases > Lung Disease Lookup > Silicosis Learn About Silicosis Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe. Key Facts There are three types of silicosis: acute, chronic, and accelerated. It occurs in workers from mines, foundries, sandblasting, and glass manufacturing. About 2 million US workers remain potentially exposed to occupational silica. There is no cure for silicosis, but it can be prevented. What Is Silicosis? There are three types of silicosis: Acute silicosis, which causes cough, weight loss, and fatigue within a few weeks or years of exposure to inhaled silica. Chronic silicosis, which appears 10 to 30 years after exposure and can affect upper lungs and sometimes cause extensive scarring. Accelerated silicosis, which occurs within 10 years of high-level exposure. Silicosis can develop within a few weeks to even decades after exposure. When people breathe silica dust, they inhale tiny particles of the mineral silica. This silica dust can cause fluid buildup and scar tissue in the lungs that cuts down your ability to breathe. This can lead to lung scarring and cough, weight loss, and fatigue.
Pyogenic granuloma (lobular capillary hemangioma[1] ) is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown. Also see the Medscape Reference article Oral Pyogenic Granuloma. Pyogenic granulomas are misnamed; they are neither infectious nor granulomatous. The lesion usually occurs in children and young adults as a solitary, glistening red papule or nodule that is prone to bleeding and ulceration. Pyogenic granulomas typically evolve rapidly over a period of a few weeks, most often on the head, neck, extremities, and upper trunk. Pyogenic granuloma often arises in pregnancy (or rarely with oral contraceptive usage), particularly on the gingiva or elsewhere in the oral mucosa, and then is termed the "pregnancy tumor." Other pyogenic granuloma variants that have been well documented include the disseminated, subcutaneous, intravenous, and medication-induced (for example, retinoid, antiretroviral, and oncologic agent) subtypes. Removal of pyogenic granuloma is indicated to alleviate any bleeding, discomfort, cosmetic distress, and diagnostic uncertainty. A number of malignant tumors may clinically mimic pyogenic granuloma, making histopathologic confirmation important if the presentation is atypical. Aside from cutaneous and oral lesions, pyogenic granuloma has been reported throughout the gastrointestinal tract and upper airway, at various ocular locations, the central nervous system, the bladder, and the internal vasculature. This article discusses only cutaneous and oral involvement.

Do you need to do a parasite cleanse? Probably... I hear from so many people suffering from symptoms of parasites - severe bloating, cramps, constipation, diarrhoea. A big problem in getting to the bottom of this (pun intended) is that the mainstream medical system really doesn’t have a way to detect, or even find most forms of parasites. They give you drugs for the symptoms, but essentially the parasites aren’t removed during that process.
Folic acid, which is also called folate, is a B vitamin. The best food sources of folic acid are fortified cereals. Folic acid plays an important role in the production of red blood cells and helps your baby's neural tube develop into her brain and spinal cord.
This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the sigmoid colon is removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining left side of the colon and the top of the rectum. The surgeon may use either sutures or special staples to make this join.
Tooth colored composite fillings are chemically bonded to teeth. For this reason, the placement of white fillings does not always require numbing the area being restored. Numbing (anesthetizing) the area is often required if tooth decay has progressed beneath the enamel layer and into the underlying dentin layer which surrounds the nerve of the tooth. Once decay is removed, the tooth is cleaned and a primer (weak acid) is applied to the area being restored. The primer opens pores in the enamel and dentin. A bonding agent is then flowed into the open pores and cured. Curing prepares the bonding agent to adhere to the tooth colored filling material. The filling material is then placed inside the tooth. After shaping the tooth colored filling material to resemble the natural anatomy of your tooth it is hardened by curing with a strong curing light. Once the white filling hardens, your bite will be checked to make sure your teeth fit together properly. If the tooth filling extends into the space between your teeth your dentist will also make sure you can floss between your teeth properly. Adjustments will be made if necessary followed by smoothing and polishing of your new filling..
In vitro fertilization, or IVF, is the most common and effective type of assisted reproductive technology to help women become pregnant. It involves fertilizing an egg outside the body, in a laboratory dish, and then implanting it in a woman's uterus. By 2016, some 6.5 million babies had been born using in-vitro fertilization (IVF). According to the Centers for Disease Control and Prevention (CDC), around 1.6 percent of babies born in the United States each year are conceived through assisted reproductive technology (ART).
The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.
