Absence of a woman's monthly menstrual period is called amenorrhea. Secondary amenorrhea is when a woman who has been having normal menstrual cycles stops getting her periods for 6 months or longer. Causes Secondary amenorrhea can occur due to natural changes in the body. For example, the most common cause of secondary amenorrhea is pregnancy. Breastfeeding and menopause are also common, but natural, causes. Women who take birth control pills or who receive hormone shots such as Depo-Provera may not have any monthly bleeding. When they stop taking these hormones, their periods may not return for more than 6 months. You are more likely to have absent periods if you: Are obese Exercise too much and for long periods of time Have very low body fat (less than 15 to 17%) Have severe anxiety or emotional distress Lose a lot of weight suddenly (for example, from strict or extreme diets or after gastric bypass surgery) Other causes include: Brain (pituitary) tumors Drugs for cancer treatment Drugs to treat schizophrenia or psychosis Overactive thyroid gland Polycystic ovarian syndrome Reduced function of the ovaries

Wetness. Even the most absorbent diaper leaves some moisture on your child's skin. And when your child's urine mixes with bacteria from his stool, it breaks down into ammonia, which can be very harsh on the skin. That's why children with frequent bowel movements or diarrhea are more prone to diaper rash.

To facilitate the delivery of fluids during labour, obstetric anaesthetists from Coventry designed a triple IV peripheral connector with a central high-flow anti-reflux valve. This connector, now rightly known as the Coventry valve, can be used for all theatre settings and is especially useful in obstetrics, ICU, HDU and orthopaedics. More details on www.mediplus.co.uk

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.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.

If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc. Because a bulging disc does not always show symptoms, many people have bulging discs without realizing it. As long as the bulging area does not press against a nearby nerve, no symptoms occur. When the bulging disc does cause a pinched nerve, however, you may begin to experience symptoms. In the lower back, the damaged disc can cause pain to travel to the hips, buttocks, legs and feet. In the cervical spine, pain can radiate from the neck, down the arm and to the fingers.
