שיער שיניים וגדילה

דר' ירדני שלום, בתי בגיל 9 כיום, סובלת מנשירת שיער קשה השיער דק ושברירי, צמיחת השיניים שלה נעצרה לפני כשנה וחצי, והשיניים הפסיקו להתחלף, ואלה שצמחו חלקית נשארו באותו מצב. 1. האם יש קשר בין התופעות? 2. האם ידוע לך על מחלה הפוגעת בחומר הבונה את השיער והשיניים?

אלי יקר, יתכן מאד שיש קשר בין הדברים וכדאי בהחלט לפנות לרופא לבירור. יכול להיות חסר בחומר מסויים שחשוב לבניית השן או קשור לחוזק השיער. כדאי לברר. בברכה,

What are the Ectodermal Dysplasia Syndromes? The ectodermal dysplasia syndromes, (abbreviated ED), are a group of genetic disorders which are identified by the absence or deficient function of at least two derivatives of the ectoderm. (i.e. teeth, hair, nails, glands). At least 150 different ED have been identified. Charles Darwin identified the first ED syndrome in the 1860s. How many people are affected by ED? We are not certain. The number is estimated as high as 7 in 10,000 births (published in the 1990 edition of The Birth Defects Encyclopedia). How does ED affect people physically? Individuals affected by ED have abnormalities of sweat glands, tooth buds, hair follicles and nail development. Some types of ED are mild while others are devastating. Other symptoms may include: deficient tears and saliva poorly functioning mucous membranes frequent respiratory infections hearing or vision deficits missing fingers or toes cleft lip and/or palate problems with immune system sensitivity to light lack of breast development other abnormalities of the ectoderm Lifespan can be affected in some rare types of ED. However, there are very few documented examples of a person affected by ED dying because of an inability to perspire. How does ED affect lives? Many individuals affected by ED cannot perspire. Air conditioning in the home, school and work place is a necessity. Most people with ED have missing or malformed teeth. Dental treatment is necessary, beginning with dentures as early as age two, multiple replacements as the child grows and perhaps dental implants thereafter. Orthodontic treatment may also be necessary. Precautions must be taken to limit upper respiratory infections and care must be provided for the skin to prevent cracking, bleeding and infection. Professional care may minimize the effects of vision or hearing deficits and surgical and/or cosmetic procedures may lessen facial and other deformities, thus reducing physical disfigurement. What causes Ectodermal Dysplasia? During pregnancy, as the baby is developing, three layers of tissue can be identified: an inner layer (the endoderm), a middle layer (the mesoderm), and an outer layer (the ectoderm). Defects in formation of the outer layer lead to ED. The reason that so many parts of the body are affected in ED is that the ectoderm contributes to many parts of the body. The ectoderm of the surface of the developing baby forms the skin, nails, hair, sweat glands, parts of the teeth, the lens of the eye, and the parts of the inner ear. Another portion of ectoderm forms the brain, spinal cord, nerves, the retina of the eye, and the pigment cells of the body. What must be done? At this time, there is no cure. The National Foundation for Ectodermal Dysplasias (NFED) is the sole organization in the world providing comprehensive services to more than 3,000 families affected by ED in 50 states and more than 50 countries. The NFED is committed to improving lives by providing information on treatment and care and promoting research.
