A leiomyoma, also known as a fibroid, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Polycythemia may occur due to increased erythropoietin production as part of a paraneoplastic syndrome.
Since not all users dial out at the same time, sharing trunk lines is cheaper than giving each phone its own private landline. [1] Extension to extension calls can be made and kept within the company for cost or security reasons. Extensions make it easier for workers to bring their telephone number with them if they change offices in the building.
Most people [note 1] with fibroids have no symptoms while others may have painful or heavy periods. [1] If large enough, they may push on the bladder, causing a frequent need to urinate. [1] They may also cause pain during penetrative sex or lower back pain. [1] [3] Someone can have one uterine fibroid or many. [1]
One example of this is laser myolysis, in which a laser is used entirely remove the fibroid, or otherwise clot the blood flow to the fibroid, causing it to die. [3] Another example is cryomyolysis, where a cryogenic gas (typically liquid nitrogen) is used to cool the tip of the needle, which freezes the fibroid. [3] [5]
As with hysteroscopic myomectomy, laparoscopic myomectomy is not generally used on very large fibroids. A study of laparoscopic myomectomies conducted between January 1990 and October 1998 examined 106 cases of laparoscopic myomectomy, in which the fibroids were intramural or subserous and ranged in size from 3 to 10 cm.

For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the ...
The peel can become deeper than 2 cm. [2] Within the chest, the lung is compressed and unable to expand (trapped lung), making it vulnerable to collapse and causing breathlessness. [7] Restrictive lung disease from fibrothorax may occur when pleural fibrosis is so severe that it involves the diaphragm and ribcage and results primarily from ...
The hard fibroma (fibroma durum) consists of many fibres and few cells, e.g. in skin it is called dermatofibroma (fibroma simplex or nodulus cutaneous). [2] A special form is the keloid , which derives from hyperplastic growth of scars .
