Warfarin is an anticoagulant medication - it is used to slow down the blood-clotting process. Anticoagulants are used to prevent blood clots which may cause vein blockages, heart attack and stroke. Warfarin is known under the brand names Warfant, Jantoven, Coumadin, Lawarin, Marevan, and Waran.
Migraine headaches are recurrent throbbing or pulsatile headaches often associated with a prodrome, nausea, vomiting, photophobia, and phonophobia. When they occur, the prodromes are characterized by visual scintillations, scotomas, dizziness, or tinnitus
patient has fever, hypotension, swelling, and erythema of his left leg. Notably, his leg is more painful to palpation than might be expected after visual inspection. These symptoms are very concerning for necrotizing fasciitis. Necrotizing fasciitis is a fulminant infection of the subcutaneous tissue that spreads rapidly along the fascial planes and leads to extensive tissue necrosis and shock. Treatment • Requires surgical debridement & broad-spectrum antibiotics
Herpes simplex encephalitis is characterized by acute-onset (<1 week) fever, headaches, seizures, altered mental status, and focal neurologic findings such as hemiparesis or cranial nerve deficits. This patient's weakness/fatigue for >1 week, heart murmur, history of drug abuse, and absence of focal neurologic deficits make endocarditis with mycotic aneurysm more likely than herpes encephalitis
-Almost all the cases of occupational transmission of HIV have been due to transmission via exposure to blood and certain body fluids. The body fluids wherein standard precautions have been recommended include semen, vaginal secretions, and any other body fluid containing visible blood. Other standard precautions, according to the Center for Disease Control and Prevention (CDC), also apply to cerebrospinal, peritoneal, pleural, pericardia!, synovial fluid, or any other tissue, even though the epidemiologic data regarding the risk of HIV transmission from these fluids is insufficient. Standard precautions do not apply to urine, sweat, tears, sputum, vomitus, and nasal secretions or feces, as long as there is no gross visible blood. The occupational transmission of HIV has never been documented from the above sources.
The fovea was moved 425 to 1,700 microm (965+/-262 microm) superiorly or inferiorly. Follow-up time was 2 to 12 months (median 8 months). Complications included macular pucker (3 eyes), subfoveal hemorrhage (2 eyes), macular hole (1 eye), and progression of cataract in phakic eyes (3 eyes). Thirteen of 20 eyes showed various degrees of proliferative vitreoretinopathy with epiretinal membrane formation over the inferior peripheral retina with the inferior retinal detachment stabilized by the silicone oil. One eye progressed to phthisis bulbi. Initial visual acuity ranged from 20/80 to 20/800 (median 20/150) and final visual acuity ranged from light perception to 20/200 (median 20/1000).
Uncomplicated acute otitis media (AOM) should be treated empirically with amoxicillin. Recurrent AOM should raise concern for beta-lactamase resistance and warrants treatment with amoxicillin-clavulanic acid. Ototopical medications are unnecessary, even if there is tympanic membrane perforation.
Bulimia (boo-LEE-me-uh) nervosa, commonly called bulimia, is a serious, potentially life-threatening eating disorder. People with bulimia may secretly binge — eating large amounts of food — and then purge, trying to get rid of the extra calories in an unhealthy way. For example, someone with bulimia may force vomiting or engage in excessive exercise. Sometimes people purge after eating only a small snack or a normal-size meal.
Laparoscopy seems to offer a safe and reliable diagnostic and therapeutic option to patients with impalpable testes. Intra-abdominal dissection allows more testes to be brought down to the scrotum. The procedure is best viewed as laparoscopy-assisted, as Orchidopexy has to be done in a conventional manner.
For both DCIS and invasive cancer, radiation therapy to the remaining breast tissue is generally recommended after surgery. A lumpectomy may also be called breast-conserving surgery, a partial mastectomy, quadrantectomy, or a segmental mastectomy. A mastectomy is the surgical removal of the entire breast.
Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis. Majority of the cases involving the lower extremities are due to a traumatic event, most commonly tibial fractures. Other causes include a crush injury or other long bone fractures in a motor vehicle accident, a tight cast or dressing after trauma, and drug overdose.
TransMedics’ proprietary Organ Care System (OCS) is the first commercial and portable warm blood perfusion organ transport system. With the OCS, doctors are able to perform “living organ transplants,” where organs are kept warm and functioning in a controlled environment from the time they are recovered to the moment they are placed in the recipient’s body.
The Estech COBRA Fusion™ 150 Surgical Ablation System combines intuitive, real-time TCRF (Temperature Controlled Radiofrequency) energy control with proprietary Versapolar technology. Versapolar™ energy delivery is the first of its kind—an adaptable and effective platform that can deliver both bipolar and monopolar energy so that surgeons can easily and efficiently create reproducible transmural lesions with more flexibility, confidence and control.
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. There are four basic types of bipolar disorder; all of them involve clear changes in mood, energy, and activity levels.
