Orofacial cleft OFC anomalies are amongst the most common congenital anomalies and the most common craniofacial anomalies. The genetic bases for many syndromic cases of OFC have been previously elucidated. Genetic associations have been described for nonsyndromic OFC as well. Importantly, etiology of OFC is known to involve interaction between genetic and environmental factors, including maternal nutrition and exposure to teratogenic agents. Furthermore, evidence points toward epigenetic as well as genetic factors influencing OFC etiology. Orofacial cleft OFC anomalies may be unilateral or bilateral and involve the lip, the palate, or both. The overall prevalence of OFC is estimated to be approximately 1 in live births, accounting for nearly one half of all craniofacial anomalies [ 1 , 2 ].
Cleft lip and cleft palate , also known as orofacial cleft , is a group of conditions that includes cleft lip, cleft palate, and both together. Cleft lip and palate are the result of tissues of the face not joining properly during development. A cleft lip or palate can be successfully treated with surgery. Cleft lip and palate occurs in about 1 to 2 per births in the developed world. If the cleft does not affect the palate structure of the mouth, it is referred to as cleft lip. Cleft lip is formed in the top of the lip as either a small gap or an indentation in the lip partial or incomplete cleft , or it continues into the nose complete cleft.
A clinical examination followed by necessary diagnostic work-up was completed for each case. Environmental causes were found in 6 children four mothers developed hyperthermia during the 2 nd month of gestation, one mother was diabetic, and one mother was a known case of epilepsy and took sodium valproate throughout her pregnancy. Six children were suffering from known genetic malformation syndromes each with Jarcho-Levin syndrome, Oral-Facial-Digital syndrome type XI, Oral-Duplication syndrome, Kabuki syndrome, Fronto-nasal dysplasia and Nager syndrome. Novel chromosomal aberrations were identified in 2 children. These findings were compared with regional and international studies. Oro-facial clefts OFCs constitute a group of structural malformations around the oral cavity and can extend on to the face resulting in oral and facial deformities.
Cleft lip with or without cleft palate is the most occurring craniofacial anomaly in human, resulting from a complex etiology involving multiple genetic and environmental factors. The defect carries lifelong morbidity and economic burden. Children with clefts will require continuous medical interventions for at least the first 18 years of life, affecting many aspects of their lives. The extent and complexity of clefts vary infinitely, later determining individual management and outcome. Identification and classification play significant roles in initial assessment of these unique cleft cases, which affect options for following correctional attempts. Some classifications even allow measurement of progress after anatomical repositioning, and success rate after surgical repairs. The challenge of developing one such widely inclusive classification is discussed.
Cleft lip and palate (CLP) are birth defects that affect the upper lip and the roof of the mouth. CLP has a multifactorial etiology, comprising both genetic and.

Среди вещей были паспорт, бумажник и очки, засунутые кем-то в один из ботинков. Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек. Беккер получил четкие инструкции: ни к чему не прикасаться, ничего не читать.
Слева и справа от алтаря в поперечном нефе расположены исповедальни, священные надгробия и дополнительные места для прихожан. Беккер оказался в центре длинной скамьи в задней части собора. Над головой, в головокружительном пустом пространстве, на потрепанной веревке раскачивалась серебряная курильница размером с холодильник, описывая громадную дугу и источая едва уловимый аромат.
