Mouth ulcers are sores that appear in the mouth, often on the inside of the cheeks. Mouth ulcers, also known as aphthous ulcers, can be painful when eating, drinking or brushing teeth. Occasional mouth ulcers are usually harmless and clear up on their own. Seek medical advice if they last longer than 3 weeks or keep coming back. Mouth ulcers cannot be caught from someone else. Up to 1 in 5 people get recurrent mouth ulcers.
Strep throat is a bacterial infection that can make your throat feel sore and scratchy. Strep throat accounts for only a small portion of sore throats. If untreated, strep throat can cause complications, such as kidney inflammation or rheumatic fever. Rheumatic fever can lead to painful and inflamed joints, a specific type of rash or heart valve damage. Strep throat is most common in children, but it affects people of all ages. If you or your child has signs or symptoms of strep throat, see your doctor for prompt testing and treatment.
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo — the sudden sensation that you're spinning or that the inside of your head is spinning. Benign paroxysmal positional vertigo causes brief episodes of mild to intense dizziness. Benign paroxysmal positional vertigo is usually triggered by specific changes in the position of your head. This might occur when you tip your head up or down, when you lie down, or when you turn over or sit up in bed. Although benign paroxysmal positional vertigo can be a bothersome problem, it's rarely serious except when it increases the chance of falls. You can receive effective treatment for benign paroxysmal positional vertigo during a doctor's office visit
Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.
Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed. Deep vein thrombosis is a serious condition because blood clots in your veins can break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow (pulmonary embolism).
What is idiopathic intracranial hypertension? Idiopathic intracranial hypertension (IIH) is a disorder that results from an increase in the pressure of the Cerebro-Spinal Fluid (CSF) that cushions and protects the brain and spinal cord. The CSF is constantly produced in the brain and reabsorbed back into the bloodstream at a fairly constant rate. This allows the fluid pressure around the brain to remain constant. What are the symptoms of idiopathic intracranial hypertension? Headaches that are generally nonspecific in location, type and frequency and can be associated with nausea and vomiting. Pulsatile tinnitus is a rhythmic or pulsating ringing heard in one or both ears. Horizontal double vision can be a sign of pressure on the 6th cranial nerve(s). Nonspecific radiating pain in the arms or legs (radicular pain). Transient obscurations of vision (TOV), which are temporary dimming or complete blacking out of vision. Visual field defects. These defects can occur in the central as well as the peripheral vision. Loss of color vision. What causes idiopathic intracranial hypertension? The cause is usually not known. A common explanation for increased pressure is a problem with the reabsorption of this fluid back into the body, which causes the pressure to increase. Sometimes the cause is determined and is referred to as “secondary” intracranial hypertension.
Nosebleeds common. Most often they are a nuisance and not a true medical problem. But they can be both. Nosebleed care Sit upright and lean forward. By remaining upright, you reduce blood pressure in the veins of your nose. This discourages further bleeding. Sitting forward will help you avoid swallowing blood, which can irritate your stomach. Pinch your nose. Use your thumb and index finger to pinch your nostrils shut. Breathe through your mouth. Continue to pinch for five to 10 minutes. Pinching sends pressure to the bleeding point on the nasal septum and often stops the flow of blood. To prevent re-bleeding, don't pick or blow your nose and don't bend down for several hours after the bleeding episode. During this time remember to keep your head higher than the level of your heart. If re-bleeding occurs, blow out forcefully to clear your nose of blood clots and spray both sides of your nose with a decongestant nasal spray containing oxymetazoline (Afrin, Mucinex Moisture Smart, others). Pinch your nose again as described above and call your doctor. When to seek emergency care The bleeding lasts for more than 20 minutes The nosebleed follows an accident, a fall or an injury to your head, including a punch in the face that may have broken your nose
According to a recent study, most people's sexual romps last about 1.5–7 minutes. But, as Dr. Harry Fisch writes in his new book The New Naked: The Ultimate Sex Education for Grownups, 45 percent of men come in two minutes or less, leaving their female partners orgasmless. Here are some ways to extend your man's sexual stamina, and more likely have an orgasm yourself in the process.
The pain is frequently severe and is described as throbbing or pulsating. Nausea is common, and many migraine patients have a watering eye, a running nose, or congestion. If these symptoms are prominent, they may lead to a misdiagnosis of sinus headaches.
In most cases, your body's immune system defeats an HPV infection before it creates warts. When warts do appear, they vary in appearance depending on which variety of HPV is involved: Genital warts. These appear as flat lesions, small cauliflower-like bumps or tiny stem-like protrusions. In women, genital warts appear mostly on the vulva but can also occur near the anus, on the cervix or in the vagina. In men, genital warts appear on the penis and scrotum or around the anus. Genital warts rarely cause discomfort or pain, though they may itch. Common warts. Common warts appear as rough, raised bumps and usually occur on the hands, fingers or elbows. In most cases, common warts are simply unsightly, but they can also be painful or susceptible to injury or bleeding.
Cluster headaches, occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.
The examination room should be quiet, warm and well lit. After you have finished interviewing the patient, provide them with a gown (a.k.a. "Johnny") and leave the room (or draw a separating curtain) while they change. Instruct them to remove all of their clothing (except for briefs) and put on the gown so that the opening is in the rear. Occasionally, patient's will end up using them as ponchos, capes or in other creative ways. While this may make for a more attractive ensemble it will also, unfortunately, interfere with your ability to perform an examination! Prior to measuring vital signs, the patient should have had the opportunity to sit for approximately five minutes so that the values are not affected by the exertion required to walk to the exam room. All measurements are made while the patient is seated. Observation: Before diving in, take a minute or so to look at the patient in their entirety, making your observations, if possible, from an out-of-the way perch. Does the patient seem anxious, in pain, upset? What about their dress and hygiene? Remember, the exam begins as soon as you lay eyes on the patient. Temperature: This is generally obtained using an oral thermometer that provides a digital reading when the sensor is placed under the patient's tongue. As most exam rooms do not have thermometers, it is not necessary to repeat this measurement unless, of course, the recorded value seems discordant with the patient's clinical condition (e.g. they feel hot but reportedly have no fever or vice versa). Depending on the bias of a particular institution, temperature is measured in either Celcius or Farenheit, with a fever defined as greater than 38-38.5 C or 101-101.5 F. Rectal temperatures, which most closely reflect internal or core values, are approximately 1 degree F higher than those obtained orally. Respiratory Rate: Respirations are recorded as breaths per minute. They should be counted for at least 30 seconds as the total number of breaths in a 15 second period is rather small and any miscounting can result in rather large errors when multiplied by 4. Try to do this as surreptitiously as possible so that the patient does not consciously alter their rate of breathing. This can be done by observing the rise and fall of the patient's hospital gown while you appear to be taking their pulse. Normal is between 12 and 20. In general, this measurement offers no relevant information for the routine examination. However, particularly in the setting of cardio-pulmonary illness, it can be a very reliable marker of disease activity. Pulse: This can be measured at any place where there is a large artery (e.g. carotid, femoral, or simply by listening over the heart), though for the sake of convenience it is generally done by palpating the radial impulse. You may find it helpful to feel both radial arteries simultaneously, doubling the sensory input and helping to insure the accuracy of your measurements. Place the tips of your index and middle fingers just proximal to the patients wrist on the thumb side, orienting them so that they are both over the length of the vessel.
A central venous catheter (CVC), also known as a central line, central venous line, or central venous access catheter, is a catheter placed into a large vein. Catheters can be placed in veins in the neck (internal jugular vein), chest (subclavian vein or axillary vein), groin (femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters). It is used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure.
A lumbar puncture (also called a spinal tap) is a procedure to collect and look at the fluid (cerebrospinal fluid, or CSF) surrounding the brain and spinal cord. During a lumbar puncture, a needle is carefully inserted into the spinal canal low in the back (lumbar area). Samples of CSF are collected.
