Primary infection with herpes simplex viruses (HSVs) is clinically more severe than recurrent outbreaks. However, most primary HSV-1 and HSV-2 infections are subclinical and may never be clinically diagnosed. Orolabial herpes Herpes labialis (eg, cold sores, fever blisters) is most commonly associated with HSV-1 infection. Oral lesions caused by HSV-2 have been identified, usually secondary to orogenital contact. Primary HSV-1 infection often occurs in childhood and is usually asymptomatic. Primary infection Symptoms of primary herpes labialis may include a prodrome of fever, followed by a sore throat and mouth and submandibular or cervical lymphadenopathy. In children, gingivostomatitis and odynophagia are also observed. Painful vesicles develop on the lips, the gingiva, the palate, or the tongue and are often associated with erythema and edema. The lesions ulcerate and heal within 2-3 weeks. Recurrences The disease remains dormant for a variable amount of time. HSV-1 reactivation in the trigeminal sensory ganglia leads to recurrences in the face and the oral, labial, and ocular mucosae. Pain, burning, itching, or paresthesia usually precedes recurrent vesicular lesions that eventually ulcerate or form a crust. The lesions most commonly occur in the vermillion border, and symptoms of untreated recurrences last approximately 1 week. Recurrent erythema multiforme lesions have been associated with orolabial HSV-1 recurrences. A recent study reported that HSV-1 viral shedding had a median duration of 48-60 hours from the onset of herpes labialis symptoms. They did not detect any virus beyond 96 hours of symptom onset.[7] Genital herpes HSV-2 is identified as the most common cause of herpes genitalis. However, HSV-1 has been increasingly identified as the causative agent in as many as 30% of cases of primary genital herpes infections likely secondary to orogenital contact. Recurrent genital herpes infections are almost exclusively caused by HSV-2. Primary infection Primary herpes genitalis occurs within 2 days to 2 weeks after exposure to the virus and has the most severe clinical manifestations. Symptoms of the primary episode typically last 2-3 weeks. In men, painful, erythematous, vesicular lesions that ulcerate most commonly occur on the penis, but they can also occur on the anus and the perineum. In women, primary herpes genitalis presents as vesicular/ulcerated lesions on the cervix and as painful vesicles on the external genitalia bilaterally. They can also occur on the vagina, the perineum, the buttocks, and, at times, the legs in a sacral nerve distribution. Associated symptoms include fever, malaise, edema, inguinal lymphadenopathy, dysuria, and vaginal or penile discharge. Females may also have lumbosacral radiculopathy, and as many as 25% of women with primary HSV-2 infections may have associated aseptic meningitis. Recurrences After primary infection, the virus may be latent for months to years until a recurrence is triggered. Reactivation of HSV-2 in the lumbosacral ganglia leads to recurrences below the waist. Recurrent clinical outbreaks are milder and often preceded by a prodrome of pain, itching, tingling, burning, or paresthesia. Individuals who are exposed to HSV and have asymptomatic primary infections may experience an initial clinical episode of genital herpes months to years after becoming infected. Such an episode is not as severe as a true primary outbreak. More than one half of individuals who are HSV-2 seropositive do not experience clinically apparent outbreaks. However, these individuals still have episodes of viral shedding and can transmit the virus to their sexual partners. Other HSV infections Localized or disseminated eczema herpeticum is also known as Kaposi varicelliform eruption. Caused by HSV-1, eczema herpeticum is a variant of HSV infection that commonly develops in patients with atopic dermatitis, burns, or other inflammatory skin conditions. Children are most commonly affected. Herpes whitlow, vesicular outbreaks on the hands and the digits, was most commonly due to infection with HSV-1. It usually occurred in children who sucked their thumbs and, prior to the widespread use of gloves, in dental and medical health care workers. The occurrence of herpes whitlow due to HSV-2 is increasingly recognized, probably due to digital-genital contact. Herpes gladiatorum is caused by HSV-1 and is seen as papular or vesicular eruptions on the face, arms, or torsos of athletes in sports involving close physical contact (classically wrestling). Disseminated HSV infection can occur in females who are pregnant and in individuals who are immunocompromised. These patients may present with atypical signs and symptoms of HSV, and the condition may be difficult to diagnose. Herpetic sycosis, a follicular infection with HSV, may present as a vesiculopustular eruption on the beard area. This infection often results from autoinoculation after shaving through a recurrent herpetic outbreak. Classically caused by HSV-1, there have been rare reports of relapsing beard folliculitis caused by type 2 HSV.[8] Neonatal HSV HSV-2 infection in pregnancy can have devastating effects on the fetus. Neonatal HSV usually manifests within the first 2 weeks of life and clinically ranges from localized skin, mucosal, or eye infections to encephalitis, pneumonitis, disseminated infection, and demise. Most women who deliver infants with neonatal HSV had no prior history, signs, or symptoms of HSV infection. Risk of transmission is highest in pregnant women who are seronegative for both HSV-1 and HSV-2 and acquire a new HSV infection in the third trimester of pregnancy. Factors that increase the risk of transmission from mother to baby include the type of genital infection at the time of delivery (higher risk with active primary infection), active lesions, prolonged rupture of membranes, vaginal delivery, and an absence of transplacental antibodies. The mortality rate for neonates is extremely high (>80%) if untreated.
Measles is a childhood infection caused by a virus. Once quite common, measles can now almost always be prevented with a vaccine. Signs and symptoms of measles include cough, runny nose, inflamed eyes, sore throat, fever and a red, blotchy skin rash. Also called rubeola, measles can be serious and even fatal for small children. While death rates have been falling worldwide as more children receive the measles vaccine, the disease still kills more than 100,000 people a year, most under the age of 5. As a result of high vaccination rates, measles has not been widespread in the United States for more than a decade. Today, the United States averages about 60 cases of measles a year, and most of them originate outside the country.

Hirsutism is stiff and pigmented body hair, appearing on the body where women don't commonly have hair — primarily the face, chest and back. When excessively high androgen levels cause hirsutism, other signs may develop over time, a process called virilization. Signs of virilization may include: Deepening voice Balding Acne Decrease in breast size Enlargement of the clitoris
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.
Pulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease. Common signs and symptoms include: Shortness of breath. This symptom typically appears suddenly and always gets worse with exertion. Chest pain. You may feel like you're having a heart attack. The pain may become worse when you breathe deeply (pleurisy), cough, eat, bend or stoop. The pain will get worse with exertion but won't go away when you rest. Cough. The cough may produce bloody or blood-streaked sputum. Other signs and symptoms that can occur with pulmonary embolism include: Leg pain or swelling, or both, usually in the calf Clammy or discolored skin (cyanosis) Fever Excessive sweating Rapid or irregular heartbeat Lightheadedness or dizziness
Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental illnesses. It often works when other treatments are unsuccessful. Much of the stigma attached to ECT is based on early treatments in which high doses of electricity were administered without anesthesia, leading to memory loss, fractured bones and other serious side effects. ECT is much safer today. Although ECT still causes some side effects, it now uses electric currents given in a controlled setting to achieve the most benefit with the fewest possible risks.
Many over-the-counter medications can help relieve heartburn. The options include: Antacids, which help neutralize stomach acid. Antacids may provide quick relief. But they can't heal an esophagus damaged by stomach acid. H-2-receptor antagonists (H2RAs), which can reduce stomach acid. H2RAs don't act as quickly as antacids, but may provide longer relief. Proton pump inhibitors, such as lansoprazole (Prevacid 24HR) and omeprazole (Prilosec OTC), which also can reduce stomach acid.
Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues. As the name implies, iron deficiency anemia is due to insufficient iron. Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath. You can usually correct iron deficiency anemia with iron supplementation. Sometimes additional tests or treatments for iron deficiency anemia are necessary, especially if your doctor suspects that you're bleeding internally.

Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.
Slicosis is caused by inhalation of unbound (free) crystalline silica dust and is characterized by nodular pulmonary fibrosis. Chronic silicosis initially causes no symptoms or only mild dyspnea but over years can advance to involve most of the lung and cause dyspnea, hypoxemia, pulmonary hypertension, and respiratory impairment. Diagnosis is based on history and chest x-ray findings. No effective treatment exists except supportive care and, for severe cases, lung transplantation.
A kidney stone may not cause symptoms until it moves around within your kidney or passes into your ureter — the tube connecting the kidney and bladder. At that point, you may experience these signs and symptoms: Severe pain in the side and back, below the ribs Pain that spreads to the lower abdomen and groin Pain that comes in waves and fluctuates in intensity Pain on urination Pink, red or brown urine Cloudy or foul-smelling urine Nausea and vomiting Persistent need to urinate Urinating more often than usual Fever and chills if an infection is present Urinating small amounts of urine Pain caused by a kidney stone may change — for instance, shifting to a different location or increasing in intensity — as the stone moves through your urinary tract.
Pancreatic cancer begins in the tissues of your pancreas — an organ in your abdomen that lies horizontally behind the lower part of your stomach. Your pancreas secretes enzymes that aid digestion and hormones that help regulate the metabolism of sugars. Pancreatic cancer often has a poor prognosis, even when diagnosed early. Pancreatic cancer typically spreads rapidly and is seldom detected in its early stages, which is a major reason why it's a leading cause of cancer death. Signs and symptoms may not appear until pancreatic cancer is quite advanced and complete surgical removal isn't possible.
Too much cholesterol in the blood can lead to cardiovascular disease. Heart disease is the No. 1 cause of death in the United States. Over 2,100 Americans die of cardiovascular disease each day, an average of one death every 40 seconds. The good news is, you can lower your cholesterol and reduce your risk of heart disease and stroke. Working with your doctor is key. It takes a team to develop and maintain a successful health program. You and your healthcare professionals each play an important role in maintaining and improving your heart health. Work with your doctor to determine your risk and the best approach to manage it. In all cases, lifestyle changes are important to reduce your risk for heart attack and stroke. In some cases, cholesterol-lowering statin medicines may also provide benefit. Learn how to make diet and lifestyle changes easy and lasting. Also make sure you understand instructions for taking medication because it won't work if you don't take it as directed. Lifestyle Changes Your diet, weight, physical activity and exposure to tobacco smoke all affect your cholesterol level. Know Your Fats Knowing which fats raise LDL cholesterol and which ones don't is the first step in lowering your risk of heart disease.
Iron is a mineral that plays a vital role in health and well-being. Without it, many bodily functions would malfunction. “The primary role of iron is to carry oxygen in the blood to every cell in the body,” says Beth Thayer, RDN, MS, director of the Center for Health Promotion and Disease Prevention at Henry Ford Health System in Detroit. Iron is an important component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs and transports it throughout the body.
Insulin resistance — also called syndrome X or metabolic syndrome— is so pervasive today that we evaluate nearly every woman who visits our clinic to determine her level of risk. Most are taken aback when they learn they either already have insulin resistance syndrome (or as I call it pre-pre diabetic) or are well on their way to developing it. Experts estimate that 25% of all Americans suffer from insulin resistance. We believe the percentage is much higher among perimenopausal women. Because insulin is one of the “major” hormones, it’s also impossible for your body to balance its “minor” hormones (estrogen, progesterone and testosterone among them) until your insulin metabolism is balanced first. To put it simply, if you have hot flashes and you are insulin resistant, it’s going to be nearly impossible to cure the hot flashes without first healing the insulin resistance. Cortisol is also a “major” hormone – to understand it’s role in hormonal balance, read our related articles on adrenal fatigue. The good news is that you can heal insulin resistance. This has been a primary focus of our practice at Women to Women for over a decade, and our approach has been quite successful. Throughout the website you will find simple solutions on how to begin to heal this problematic syndrome.
