An idiopathic disease is any disease with an unknown cause or mechanism of apparent spontaneous origin.
57-481: Kyphosis (from Greek κυφός (kyphos) 'hump') is an abnormally excessive convex curvature of the spine as it occurs in the thoracic and sacral regions. Abnormal inward concave lordotic curving of the cervical and lumbar regions of the spine is called lordosis . It can result from degenerative disc disease ; developmental abnormalities, most commonly Scheuermann's disease ; Copenhagen disease , osteoporosis with compression fractures of
114-660: A randomised controlled trial . The Milwaukee brace is one particular body brace that is often used to treat kyphosis in the US. Modern CAD/CAM braces are used in Europe to treat different types of kyphosis. These are much easier to wear and have better in-brace corrections than reported for the Milwaukee brace. Since there are different curve patterns ( thoracic , thoracolumbar , and lumbar ), different types of brace are in use, with different advantages and disadvantages. In Germany,

There are many English words of Greek origin . Greek is an independent branch of the Indo-European language family. The ancient language most closely related to it may be ancient Macedonian , which, by most accounts,

With some other medical conditions, the root cause for a large percentage of all cases has not been established—for example, focal segmental glomerulosclerosis or ankylosing spondylitis ; the majority of these cases are deemed idiopathic. Certain medical conditions, when idiopathic, notably some forms of epilepsy and stroke , are preferentially described by
285-558: A fairly stable set of consonantal contrasts . The main phonological changes occurred during the Hellenistic and Roman period (see Koine Greek phonology for details): In all its stages, the morphology of Greek shows an extensive set of productive derivational affixes , a limited but productive system of compounding and a rich inflectional system. Although its morphological categories have been fairly stable over time, morphological changes are present throughout, particularly in
342-560: A faster, more convenient cursive writing style with the use of ink and quill . The Greek alphabet consists of 24 letters, each with an uppercase ( majuscule ) and lowercase ( minuscule ) form. The letter sigma has an additional lowercase form (ς) used in the final position of a word: In addition to the letters, the Greek alphabet features a number of diacritical signs : three different accent marks ( acute , grave , and circumflex ), originally denoting different shapes of pitch accent on
399-540: A foreign language. It is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, " Homeric Greek is probably closer to Demotic than 12-century Middle English is to modern spoken English ". Greek is spoken today by at least 13 million people, principally in Greece and Cyprus along with a sizable Greek-speaking minority in Albania near
456-806: A potential cause of kyphosis, can be confirmed with a bone density scan. Postural thoracic kyphosis can often be treated with posture reeducation and focused strengthening exercises. Idiopathic thoracic kyphosis due to vertebral wedging, fractures, or vertebral abnormalities is more difficult to manage, since assuming a correct posture may not be possible with structural changes in the vertebrae. Children who have not completed their growth may show long-lasting improvements with bracing. Exercises may be prescribed to alleviate discomfort associated with overstretched back muscles. A variety of gravity-assisted positions or gentle traction can minimize pain associated with nerve root impingement. Surgery may be recommended for severe idiopathic kyphosis. Body braces showed benefit in
513-445: A procedure called a kyphoplasty may arrest the deformity and relieve the pain. Kyphoplasty is a minimally invasive procedure, requiring only a small opening in the skin. The main goal is to return the damaged vertebra as close as possible to its original height. One of the most well-known and enduring depictions of kyphosis is Quasimodo , the eponymous hero of Victor Hugo 's 1831 novel The Hunchback of Notre-Dame , which solidified
570-551: A standard treatment for both Scheuermann's disease and lumbar kyphosis is the Schroth method, a system of physical therapy for scoliosis and related spinal deformities. It involves lying supine, placing a pillow under the scapular region and posteriorly stretching the cervical spine. In China, many people use spinal care mattresses to correct kyphosis while sleeping. Surgical treatment can be used in severe cases. In patients with progressive kyphotic deformity due to vertebral collapse,

The word cryptogenic ( crypto- , "hidden" + -gen , "cause" + -ic ) has a sense that is synonymous with idiopathic and a sense that is contradistinguished from it. Some disease classifications prefer the use of the synonymous term cryptogenic disease as in cryptogenic stroke , and cryptogenic epilepsy . The use of cryptogenic

The Greek language is conventionally divided into the following periods: In the modern era, the Greek language entered a state of diglossia : the coexistence of vernacular and archaizing written forms of the language. What came to be known as the Greek language question was a polarization between two competing varieties of Modern Greek: Dimotiki ,

In the sense of a deformity, it is the pathological curving of the spine , where parts of the spinal column lose some or all of their lordotic profile. This causes a bowing of the back , seen as a slouching posture. Kyphosis is distinguished from scoliosis , a condition in which
969-519: Is protected and promoted officially as a regional and minority language in Armenia, Hungary , Romania, and Ukraine. It is recognized as a minority language and protected in Turkey by the 1923 Treaty of Lausanne .

In Greek, the question mark is written as the English semicolon, while the functions of the colon and semicolon are performed by a raised point (•), known as the ano teleia ( άνω τελεία ). In Greek the comma also functions as a silent letter in a handful of Greek words, principally distinguishing ό,τι ( ó,ti , 'whatever') from ότι ( óti , 'that'). Ancient Greek texts often used scriptio continua ('continuous writing'), which means that ancient authors and scribes would write word after word with no spaces or punctuation between words to differentiate or mark boundaries.

In its modern form , Greek is the official language of Greece and Cyprus and one of the 24 official languages of the European Union . It is spoken by at least 13.5 million people today in Greece, Cyprus, Italy, Albania, Turkey , and the many other countries of the Greek diaspora .

It is believed that "about half (50%) of children with learning disabilities and approximately 60% of children with congenital disabilities (disabilities which are apparent from birth) do not have
1596-492: The nominal and verbal systems. The major change in the nominal morphology since the classical stage was the disuse of the dative case (its functions being largely taken over by the genitive ). The verbal system has lost the infinitive , the synthetically -formed future, and perfect tenses and the optative mood . Many have been replaced by periphrastic ( analytical ) forms. Pronouns show distinctions in person (1st, 2nd, and 3rd), number (singular, dual , and plural in

A normal thoracic spine extends from the 1st thoracic to the 12th thoracic vertebra and should have a slight kyphotic angle, ranging from 20° to 45°. When the "roundness" of the upper spine increases past 45° it is called kyphosis or "hyperkyphosis". Scheuermann's kyphosis is the most classic form of hyperkyphosis and is the result of wedged vertebrae that develop during adolescence. The cause

The variant of the alphabet in use today is essentially the late Ionic variant, introduced for writing classical Attic in 403 BC. In classical Greek, as in classical Latin, only upper-case letters existed. The lower-case Greek letters were developed much later by medieval scribes to permit
1767-495: The Greek language was the Cypriot syllabary (also a descendant of Linear A via the intermediate Cypro-Minoan syllabary ), which is closely related to Linear B but uses somewhat different syllabic conventions to represent phoneme sequences. The Cypriot syllabary is attested in Cyprus from the 11th century BC until its gradual abandonment in the late Classical period, in favor of the standard Greek alphabet. Greek has been written in

1824-629: The Greek verb have likewise remained largely the same over the course of the language's history but with significant changes in the number of distinctions within each category and their morphological expression. Greek verbs have synthetic inflectional forms for: Many aspects of the syntax of Greek have remained constant: verbs agree with their subject only, the use of the surviving cases is largely intact (nominative for subjects and predicates, accusative for objects of most verbs and many prepositions, genitive for possessors), articles precede nouns, adpositions are largely prepositional, relative clauses follow
1881-685: The Greek-Albanian border. A significant percentage of Albania's population has knowledge of the Greek language due in part to the Albanian wave of immigration to Greece in the 1980s and '90s and the Greek community in the country. Prior to the Greco-Turkish War and the resulting population exchange in 1923 a very large population of Greek-speakers also existed in Turkey , though very few remain today. A small Greek-speaking community

Possible complications include inflammation of the soft tissue or deep inflammatory processes, breathing impairments, bleeding, and nerve injuries. According to the latest evidence, the actual rate of complications may be substantially higher. Even among those who do not develop serious complications, 5% of patients require reoperation within five years of

The division into conventional periods is, as with all such periodizations, relatively arbitrary, especially because, in all periods, Ancient Greek has enjoyed high prestige, and the literate borrowed heavily from it. Across its history, the syllabic structure of Greek has varied little: Greek shows a mixed syllable structure, permitting complex syllabic onsets but very restricted codas. It has only oral vowels and

2394-399: The noun they modify and relative pronouns are clause-initial. However, the morphological changes also have their counterparts in the syntax, and there are also significant differences between the syntax of the ancient and that of the modern form of the language . Ancient Greek made great use of participial constructions and of constructions involving the infinitive, and the modern variety lacks
2451-706: The older periods of Greek, loanwords into Greek acquired Greek inflections, thus leaving only a foreign root word. Modern borrowings (from the 20th century on), especially from French and English, are typically not inflected; other modern borrowings are derived from Albanian , South Slavic ( Macedonian / Bulgarian ) and Eastern Romance languages ( Aromanian and Megleno-Romanian ). Greek words have been widely borrowed into other languages, including English. Example words include: mathematics , physics , astronomy , democracy , philosophy , athletics , theatre, rhetoric , baptism , evangelist , etc. Moreover, Greek words and word elements continue to be productive as
2508-489: The percentage of cases designated as idiopathic decreases. The word essential is sometimes synonymous with idiopathic (as in essential hypertension , essential thrombocythemia , and essential tremor ) and the same is true of primary (as in primary biliary cholangitis , or primary amenorrhea ), with the latter term being used in such cases to contrast with secondary in the sense of "secondary to [i.e., caused by] some other condition." Another, less common synonym

The legendary Comprachicos of the sort popularized in Hugo's similar work The Man Who Laughs are instead described as being able to turn able-bodied young children into hunchbacks, alongside a variety of other deformities, using poisons and mutilation, before selling their results into bondage as court dwarfs or freak show performers. Early horror films developed

The earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the world's oldest recorded living language . Among the Indo-European languages, its date of earliest written attestation
2679-435: The procedure, and in general it is not yet clear what one would expect from spine surgery during the long-term. Given that the signs and symptoms of spinal deformity cannot be changed by surgical intervention, surgery remains essentially a cosmetic choice. However, the cosmetic effects of surgery are not necessarily stable. There are several kinds of kyphosis ( ICD-10 codes are provided): Kyphosis can be graded in severity by
2736-526: The spine has a sideways curve. While most cases of kyphosis are mild and only require routine monitoring, serious cases can be debilitating. High degrees of kyphosis can cause severe pain and discomfort, breathing and digestion difficulties, cardiovascular irregularities, neurological compromise and, in the more severe cases, significantly shortened life spans. These types of high-end curves typically do not respond well to conservative treatment and almost always warrant spinal fusion surgery, which can restore
2793-437: The stressed vowel; the so-called breathing marks ( rough and smooth breathing ), originally used to signal presence or absence of word-initial /h/; and the diaeresis , used to mark the full syllabic value of a vowel that would otherwise be read as part of a diphthong. These marks were introduced during the course of the Hellenistic period. Actual usage of the grave in handwriting saw a rapid decline in favor of uniform usage of
2850-552: The synonymous term of cryptogenic . The term 'idiopathic' derives from Greek ἴδιος idios "one's own" and πάθος pathos "suffering", so idiopathy means approximately "a disease of its own kind". Diseases where the cause is seen as wholly or partly idiopathic include: Advances in medical science improve the understanding of causes of diseases and the classification of diseases; thus, regarding any particular condition or disease, as more root causes are discovered and as events that seemed spontaneous have their origins revealed,
2907-447: The various stages of the Greek language are often emphasized. Although Greek has undergone morphological and phonological changes comparable to those seen in other languages, never since classical antiquity has its cultural, literary, and orthographic tradition been interrupted to the extent that one can speak of a new language emerging. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than
