The lumps may be hard or rubbery and can appear as a single breast lump that may be large or small. Fibrocystic changes also can appear as thickening of the breast tissue. Fibrocystic changes can occur in one or both breasts and are the most common cause of benign breast lumps in women age 35 to 50.

How Breast Milk is Produced?
How Breast Milk is Produced? samer kareem 19,901 Views • 3 years ago

Prompted by the hormone prolactin, the alveoli take proteins, sugars, and fat from your blood supply and make breast milk. A network of cells surrounding the alveoli squeeze the glands and push the milk out into the ductules, which lead to a bigger duct.

The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. First, for those impatient, short answers to the mini-questions (if you're reading this in the news feed, you may want to click through for the question details): No one knows why we evolved 2 kidneys and one liver.

EHEC Outbreak News - Expecting more cases in Germany
EHEC Outbreak News - Expecting more cases in Germany Scott Stevens 6,788 Views • 3 years ago

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.

Closure of Wound by Stress Relaxation
Closure of Wound by Stress Relaxation samer kareem 1,749 Views • 3 years ago

Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The TopClosure tension-relief system (TRS) is a novel device for wound closure closure, providing secured attachment to the skin through a wide area of attachment, in an adjustable manner, enabling primary closure of medium to large skin defects. The aim of this study was to evaluate the efficiency of the TopClosure TRS as a substitute for skin grafting and flaps for primary closure of large soft tissue defects by stress-relaxation. We present three demonstrative cases requiring resection of large to huge tumors customarily requiring closure by skin graft or flaps. TRS was applied during surgery serving as a tension-relief platform for tension sutures, to enable primary skin-defect closure by cycling of stress-relaxation, and following surgery as skin-secure system until complete wound closure. All skin defects ranging from 7 to 26 cm in width were manipulated by the TRS through stress-relaxation, without undermining of skin, enabling primary skin closure and eliminating the need for skin grafts and flaps. Immediate wound closure ranged 26 to 135 min. TRS was applied for 3 to 4 weeks. Complications were minimal and donor site morbidity was eliminated. Surgical time, hospital stay and costs were reduced and wound aesthetics were improved. In this case series we present a novel technology that enables the utilization of the viscoelastic properties of the skin to an extreme level, extending the limits of primary wound closure by the stress-relaxation principle. This is achieved via a simple device application that may aid immediate primary wound closure and downgrade the complexity of surgical procedures for a wide range of applications on a global scale.
