What Are Sleep Disorders? Circadian Rhythm Disorders Typically, people sleep at night -- thanks not only to the conventions of the 9-to-5 workday, but also to the close interaction between our natural sleep and alertness rhythms, which are driven by an internal "clock." This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. It sits just above the nerves leaving the back of our eyes. Light and exercise "reset" the clock and can move it forward or backward. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day"). Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late), and advanced sleep phase syndrome (you fall asleep and wake up too early).

Initial treatment of a deviated septum may be directed at managing the symptoms of the tissues lining the nose, which may then contribute to symptoms of nasal obstruction and drainage. Your doctor may prescribe: Decongestants. Decongestants are medications that reduce nasal tissue swelling, helping to keep the airways on both sides of your nose open. Decongestants are available as a pill or as a nasal spray. Use nasal sprays with caution, however. Frequent and continued use can create dependency and cause symptoms to be worse (rebound) after you stop using them. Decongestants have a stimulant effect and may cause you to be jittery as well as elevate your blood pressure and heart rate. Antihistamines. Antihistamines are medications that help prevent allergy symptoms, including obstruction and runny nose. They can also sometimes help nonallergic conditions such as those occurring with a cold. Some antihistamines cause drowsiness and can affect your ability to perform tasks that require physical coordination, such as driving. Nasal steroid sprays. Prescription nasal corticosteroid sprays can reduce inflammation in your nasal passage and help with obstruction or drainage. It usually takes from one to three weeks for steroid sprays to reach their maximal effect, so it is important to follow your doctor's directions in using them. Medications only treat the swollen mucus membranes and won't correct a deviated septum.

The E.coli bacteria has claimed 14 lives and infected more than 300 hundred in the country. It has now spread to other European states.

Facing an increasing number of cases, German health authorities warned people to avoid eating raw cucumber, tomatoes and lettuce.

Reinhard Burger, President of Robert Koch Institute, said, "As for the present situation there is no reason to give the all-clear yet and it is possible the original source of the infection is still active and could lead to further infections."

The first cases of the EHEC outbreak were noticed in Northern Germany, but infections are now spreading across the country.

Cases haves spiked compared to other years, and are still rising.

Daniel Bahr, German Health Minister, said, "The result is that we unfortunately still have to prepare for a rising number of cases. Exercising caution is still recommended and we ask our citizens to be particularly careful. "

But, the German government says it's working around the clock to stop the outbreak and clarify how it arose.

Ilse Aigner, German Agriculture Minister, said, "Together, we face a big challenge to piece together hundreds or thousands of mosaic pieces from Germany and abroad into an overall picture that gives us a clear answer on how this terrible infection arose. "

In the meantime, experts are advising not to eat pre-packaged or prepared salad, which may contain the bacteria.
