Pregnancy occurs when an egg is fertilized by a sperm, grows inside a woman's uterus (womb), and develops into a baby. In humans, this process takes about 264 days from the date of fertilization of the egg, but the obstetrician will date the pregnancy from the first day of the last menstrual period (280 days 40 weeks).

Spider Veins Treatment
Spider Veins Treatment Mohamed Ibrahim 7,473 Views • 2 years ago

Several options are available to remove spider veins — thin red lines or weblike networks of blood vessels that appear on your legs and feet. Spider veins are usually harmless, though they can sometimes cause aching, burning or pain, especially when you've been standing for long periods. If you have symptoms or are concerned about the appearance of spider veins, treatment options include: Sclerotherapy. In this procedure, your doctor injects the veins with a solution that scars and closes those veins, causing the blood to reroute through healthier veins. In a few weeks, treated spider veins fade. Although the same vein may need to be injected more than once, sclerotherapy is usually effective if done correctly. Sclerotherapy doesn't require anesthesia and can be done in your doctor's office. Side effects include swelling, itching and skin color changes in the treated area. Laser surgery. Laser surgery works by sending strong bursts of light into the vein that make the vein slowly fade and disappear. No incisions or needles are used. The treatment is often less effective than sclerotherapy, particularly for larger veins. Side effects may include redness, bruising, itching, swelling and permanent skin tone changes. After treatment, blood vessels fade over several months, but they may not disappear completely. Also, new spider veins can develop in the same area.

Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome samer kareem 12,756 Views • 2 years ago

Ehlers-Danlos syndrome is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of Ehlers-Danlos syndrome, which vary from mildly loose joints to life-threatening complications. Previously, there were more than 10 recognized types of Ehlers-Danlos syndrome, differentiated by Roman numerals. In 1997, researchers proposed a simpler classification that reduced the number of major types to six and gave them descriptive names: the classical type (formerly types I and II), the hypermobility type (formerly type III), the vascular type (formerly type IV), the kyphoscoliosis type (formerly type VIA), the arthrochalasia type (formerly types VIIA and VIIB), and the dermatosparaxis type (formerly type VIIC). This six-type classification, known as the Villefranche nomenclature, is still commonly used. The types are distinguished by their signs and symptoms, their underlying genetic causes, and their patterns of inheritance. Since 1997, several additional forms of the condition have been described. These additional forms appear to be rare, affecting a small number of families, and most have not been well characterized.

Nelson's syndrome
Nelson's syndrome samer kareem 4,823 Views • 2 years ago

Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]
