Electrical Injuries
Electrical Injuries samer kareem 2,198 Views • 2 years ago

Electrical injuries can present with a variety of problems, including cardiac or respiratory arrest, coma, blunt trauma, and severe burns of several types. It is important to establish the type of exposure (high or low voltage), duration of contact, and concurrent trauma. Low-voltage AC injury without loss of consciousness and/or arrest These injuries are exposures of less than 1000V and usually occur in the home or office setting. Typically, children with electrical injuries present after biting or chewing on an electrical cord and suffer oral burns. Adults working on home appliances or electrical circuits can also experience these electrical injuries. Low-voltage AC may result in significant injury if there is prolonged, tetanic muscle contraction. Low-voltage AC injury with loss of consciousness and/or arrest In respiratory arrest or ventricular fibrillation that is not witnessed, an electrical exposure may be difficult to diagnose. All unwitnessed arrests should include this possibility in the differential diagnosis. Query EMS personnel, family, and coworkers about this possibility. Inquire if a scream was heard before the patient’s collapse; this may be due to involuntary contraction of chest wall muscles from electrical current. High-voltage AC injury without loss of consciousness and/or arrest Usually high-voltage injuries do not cause loss of consciousness but instead cause devastating thermal burns. In occupational exposures, details of voltage can be obtained from the local power company. High-voltage AC injury with loss of consciousness and/or arrest This is an unusual presentation of high-voltage AC injuries, which do not often cause loss of consciousness. History may need to come from bystanders or EMS personnel. Direct current (DC) injury These injuries typically cause a single muscle contraction that throws the victim away from the source. They are rarely associated with loss of consciousness unless there is severe head trauma, and victims can often provide their own history. Conducted electrical devices Conducted electrical weapons (CEWs) such as tasers are weapons used by law enforcement that deliver high-voltage current that is neither true AC or DC but is most like a series of low-amplitude DC shocks.[16] They can deliver 50,000 V in a 5-second pulse, with an average current of 2.1 mA.[17] Though they have been temporally associated with deaths in the law enforcement setting, conducted electrical devices (CEDs) in healthy volunteers have been shown to be safe without evidence of delayed arrhythmia or cardiac damage as measured by troponin I.[18, 17] One study of their use in 1201 law enforcement incidents showed mostly superficial puncture wounds from the device probes, and significant injuries only from trauma subsequent to shock, not from the device itself. Of 2 deaths in custody, neither was related to CEW exposure.[19]

Ovarian Cancer

Ovarian cancer warning signs include ongoing pain or cramps in the belly or back, abnormal vaginal bleeding, nausea, and bloating. Depending on the cancer stage, ovarian cancer treatment includes surgery and chemotherapy.

Neurotransmission
Neurotransmission samer kareem 1,478 Views • 2 years ago

Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.

Giant lipoma
Giant lipoma samer kareem 7,787 Views • 2 years ago

Lipomas are slow-growing soft tissue tumours that rarely reach a size larger than 2 cm. Lesions larger than 5 cm, so-called giant lipomas, can occur anywhere in the body but are seldom found in the upper extremities. The authors present their experiences with eight patients having giant lipomas of the upper extremity. In addition, a review of the literature, and a discussion of the appropriate evaluation and management are included.

HIV AIDS prevention
HIV AIDS prevention Liz L 9,163 Views • 2 years ago

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.

Buerger Disease
Buerger Disease samer kareem 1,415 Views • 2 years ago

Buerger's disease (thromboangiitis obliterans) is a rare disease of the arteries and veins in the arms and legs. In Buerger's disease, your blood vessels become inflamed, swell and can become blocked with blood clots (thrombi). This eventually damages or destroys skin tissues and may lead to infection and gangrene. Buerger's disease usually first shows in your hands and feet and may eventually affect larger areas of your arms and legs. Virtually everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco, such as chewing tobacco. Quitting all forms of tobacco is the only way to stop Buerger's disease. For those who don't quit, amputation of all or part of a limb is sometimes necessary.
