A cough is basically a reflex action so the airways can be cleared of phlegm, mucus and other irritants like dust and smoke. An inflammation of the upper respiratory tract due to a virus could also cause a cough.

Coughing can be symptomatic of many conditions including bronchitis, asthma, the common cold, flu, whooping cough or smoking. There are even some prescribed medicines that can cause coughing such as ACE-inhibitors which are used to treat heart failure.

Sometimes a cough can be a symptom of an underlying serious medical condition such as heart failure, lung cancer, tuberculosis, pneumonia or a pulmonary embolism (which is a clot on the lung). Coughs that have been caused by things like flu or the common cold normally disappear after a few days, but coughs that have been caused by an infection of the lung, such as bronchitis, could persist for several weeks, even after the infection has cleared up and this is due to the inflammation of the airways which usually take a while to clear up.

Cough Mechanism and Receptors

If someone has been suffering from a cough for more than a couple of weeks after having a viral infection, they should go to their doctor for medical advice.

The testicles are found within the scrotum which is a loose sac of skin hanging down behind the penis.  The function of the testicles is to produce sperm and the male sex hormone testosterone.  Most of the time any lumps or swelling within the testicles are benign but it is natural for people to worry when they have found a lump.

Testicular torsion results in swelling of the testicles if the testicle has become twisted.  This interrupts blood flow and causes a large tender distension.  It often happens in developing boys who are experiencing puberty but has also been know to happen in men in their 20’s although it is quite rare.  Testicular torsion is a medical emergency due to the fact that it needs to be rectified by surgery within 6 hours or there is a risk that the testicle will be lost.

Symptoms of testicular torsion include nausea; vomiting; swelling of the scrotum; fever; abdominal pain; the need to urinate often; and, excruciating pain in one testicle.  The cause of testicular torsion results from a spermatic cord that is too long.  The spermatic cord is where the testicles hang from and in some boys this cord is too long leading to increased movement of the testicle which means the cord becoming twisted.  If it twists too much it will cut off the blood supply and the testicle will die.  Testicular torsion can sometimes just happen for no reason at all or it can be the result of strenuous exercise or other physical activity.

An ultrasound scan can be done to confirm suspicion of testicular torsion. Surgery needs to take place almost immediately to save the testicle.  The surgeon will have to cut the scrotum and untwist the cord.  He will then sew the cord to the scrotum to prevent this happening again.

Testicular Torsion

Vaginitis is the name given to an infection of the vagina.  Symptoms of vaginitis include a sore itching vagina with possible abnormal discharge.  There are various types of vaginitis and each type has its own cause and symptoms.  These different types are yeast infections, bacterial vaginosis, non-infectious vaginitis, and trichomoniasis.

Yeast or Candida infections are the most common type of vaginitis and are caused by an excess of the fungus Candida growing in the vagina.  Symptoms of yeast infections include a thick white discharge which causes the vagina to become itchy and red.

Vaginitis

Bacterial vaginosis is a frequent infection which affects women of reproductive age and is caused by bacteria in the vagina.  Symptoms of bacterial vaginosis can include a thin smelly vaginal discharge although some women find they have no symptoms at all and only become aware of the infection during a visit to the gynecologist.

Non-infectious vaginitis can be caused by a reaction to products used such as soaps, fabric softeners, douches, vaginal sprays or spermicidal products.  It can cause the vagina to become itchy or burn and is accompanied by a vaginal discharge.

Trichomoniasis is an infection of the vagina which is caused by a single cell parasite.  This form of vaginitis is a sexually transmitted disease and will cause soreness, itching, and burning of the vagina.  It can also cause a burning feeling when urinating.

Each type of vaginitis has its own treatment.  An anti-yeast infection is used to treat yeast infection.  An antibiotic is used to treat bacterial vaginosis as there is no remedy which can be purchased over the counter.  In order to treat non-infectious vaginitis it is necessary to cease using the product which caused the reaction and a cream can be used to relieve symptoms. Trichomoniasis is treated with an antibiotic but it is important to avoid any sexual contact until it has been treated.
