Pierre Robin (surgeon)
Pierre Robin (; 1866–1950) was a French people, French Oral medicine, stomatologist (Dentist, dental surgeon) from Paris. He was professor at the French School of Stomatology, and from 1914, he was editor-in-chief of the Revue de Stomatologie. In a series of articles, beginning in 1923, Robin described the combined condition of Micrognathism, underdevelopment of the mandible and glossoptosis, retraction of the tongue. His first papers described clinical observations in young adults who had small jaws, and who also had upper airway obstruction during sleep. Robin proposed a novel idea of holding the lower jaw forward and mouth open, through the use of special dental splints; and specifically with an invented and novel device he later called the "Monobloc". This invention predated the eventual development of mandibular advancement splints used by dentists in sleep medicine today. In a series of articles, Robin demonstrated that in adults, small mandibles lead to a series of both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in Brittany, Occi ...

Oral Medicine
An oral medicine or stomatology doctor (or stomatologist) has received additional specialized training and experience in the diagnosis and management of oral mucosal abnormalities (growths, ulcers, infection, allergies, immune-mediated and autoimmune disorders) including oral cancer, salivary gland disorders, temporomandibular disorders (e.g.: problems with the TMJ) and facial pain (due to musculoskeletal or neurologic conditions), taste and smell disorders; and recognition of the oral manifestations of systemic and infectious diseases. It lies at the interface between medicine and dentistry. An oral medicine doctor is trained to diagnose and manage patients with disorders of the orofacial region, essentially as a "physician of the mouth." History The importance of the mouth in medicine has been recognized since the earliest known medical writings. For example, Hippocrates, Galen and others considered the tongue to be a "barometer" of health, and emphasized the diagnostic and prog ...

Dentist
A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry (the diagnosis, prevention, management, and treatment of diseases and conditions of the mouth, oral cavity and other aspects of the craniofacial complex including the temporomandibular joint). The dentist's Dental auxiliary, supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and sometimes dental therapists. History Middle Ages In China as well as France, the first people to perform dentistry were barbers. They have been categorized into 2 distinct groups: guild of barbers and lay barbers. The first group, the Guild of Barbers, was created to distinguish more educated and qualified dental surgeons from lay barbers. Guild barbers were trained to do complex surgeries. The second group, the lay barbers, were qualified to perform regular hygienic services such as shaving and tooth extraction as w ...

Micrognathism
Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia. It is common in infants, but is usually self-corrected during growth, due to the jaws' increasing in size. It may be a cause of abnormal tooth alignment and in severe cases can hamper feeding. It can also, both in adults and children, make intubation difficult, either during anesthesia or in emergency situations. Causes While not always pathological, it can present as a birth defect in multiple syndromes including: * Catel–Manzke syndrome * Bloom syndrome * Coffin–Lowry syndrome * Congenital rubella syndrome * Cri du chat syndrome * DiGeorge syndrome * Ehlers–Danlos syndrome * Fetal alcohol syndrome * Hallermann–Streiff syndrome * Hemifacial microsomia (as part of Goldenhar syndrome) * Incontinentia pigmenti * Juvenile idiopathic arthritis * Marfan syndrome * Möbius syndrome * Noonan syndrome * Pierre Robin syndrome * Prader–Willi syndrome * Progeria * Silve ...

Glossoptosis
Glossoptosis is a medical condition and abnormality which involves the downward displacement or retraction of the tongue. It may cause non-fusion of the hard palate, causing cleft palate. It is one of the features of Pierre Robin sequence and Down syndrome Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with physical growth delays, mild to moderate intellectual d .... References Congenital disorders of musculoskeletal system Tongue disorders {{med-sign-stub ...

Sleep Medicine
Sleep medicine is a medical specialty or subspecialty devoted to the diagnosis and therapy of sleep disturbances and sleep disorder, disorders. From the middle of the 20th century, research has provided increasing knowledge and answered many questions about sleep-wake functioning. The rapidly evolving field has become a recognized medical subspecialty in some countries. Dental sleep medicine also qualifies for board certification in some countries. Properly organized, minimum 12-month, postgraduate training programs are still being defined in the United States. In some countries, the sleep researchers and the physicians who treat patients may be the same people. The first sleep clinics in the United States were established in the 1970s by interested physicians and allied health professions, technicians; the study, diagnosis and treatment of obstructive sleep apnea were their first tasks. As late as 1999, virtually any American physician, with no specific training in sleep medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligohydramnios
Oligohydramnios is a medical condition in pregnancy characterized by a deficiency of amniotic fluid, the fluid that surrounds the fetus in the abdomen, in the amniotic sac. It is typically diagnosed by ultrasound when the amniotic fluid index (AFI) measures less than 5 cm or when the single deepest pocket (SDP) of amniotic fluid measures less than 2 cm. Amniotic fluid is necessary to allow for normal fetal movement, lung development, and cushioning from uterine compression. Low amniotic fluid can be attributed to a maternal, fetal, placental or idiopathic cause and can result in poor fetal outcomes including death. The prognosis of the fetus is dependent on the etiology, gestational age at diagnosis, and the severity of the oligohydramnios. The opposite of oligohydramnios is polyhydramnios, or an excess of amniotic fluid. Etiology The amount of amniotic fluid available is based on how much fluid is produced and how much is removed from the amniotic sac. In the first trimester, t ...

Pierre Robin Sequence
Pierre Robin sequence (; abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities. The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway. A wide, U-shaped cleft palate is commonly also present. PRS is not merely a syndrome, but rather it is a sequence—a series of specific developmental malformations which can be attributed to a single cause. Signs and symptoms PRS is characterized by an unusually small mandible, posterior displacement or retraction of the tongue, and upper airway obstruction. Cleft palate (incomplete closure of the roof of the mouth) is present in the majority of patients. Hearing loss and speech difficulty are often associated with PRS. Causes Mechanical basis The physical craniofacial deformities of PRS may be the result of a mechanical problem in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
