Error analysis of functional articulation disorders in children / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To explore the clinical characteristic of functional articulation disorders in children and provide more evidence for differential diagnosis and speech therapy.</p><p><b>METHODS</b>172 children with functional articulation disorders were grouped by age. Children aged 4-5 years were assigned to one group, and those aged 6-10 years were to another group. Their phonological samples were collected and analyzed.</p><p><b>RESULTS</b>In the two groups, substitution and omission (deletion) were the mainly articulation errors in these children, dental consonants were the main wrong sounds, and bilabial and labio-dental were rarely wrong. In age 4-5 group, sequence according to the error frequency from the highest to lowest was dental, velar, lingual, apical, bilabial, and labio-dental. In age 6-10 group, the sequence was dental, lingual, apical, velar, bilabial, labio-dental. Lateral misarticulation and palatalized misarticulation occurred more often in age 6-10 group than age 4-5 group and were only found in lingual and dental consonants in two groups.</p><p><b>CONCLUSION</b>Misarticulation of functional articulation disorders mainly occurs in dental and rarely in bilabial and labio-dental. Substitution and omission are the most often occurred errors. Lateral misarticulation and palatalized misarticulation occur mainly in lingual and dental consonants.</p>

Survey of the patients with cleft lip and palate in China who were funded for surgery by the Smile Train Program from 2000 to 2002 / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cleft lip (CL) and cleft palate (CP) are two of the most frequent congenital malformations. Many epidemiologic studies on this deformity have been conducted worldwide, often producing inconsistent results. This study assessed epidemiology and some genetic aspects of cleft lip and palate in a Chinese sample from the Smile Train Program and to compare with other methodologically sound surveys.</p><p><b>METHODS</b>The general information, family history, classification of cleft and associated malformations of 8000 CL and CP surgery patients were analyzed.</p><p><b>RESULTS</b>Of the 8000 cases, 7812 had complete data. The distribution of cleft types is 17.04% with CP, 23.39% with CL and 59.58% with cleft lip and palate (CLP). Unilateral clefts were more common than bilateral, with unilateral to bilateral ratios being 10.4:1 for CL, and 3.42:1 for CLP. The overall male:female ratio was 2.01:1. Left sided defects were more common than right sided regardless of sex, 1.90:1 for CL and 1.96:1 for CLP. CLP and CL were more common in males than in females with sex ratios (SR) of 2.88:1 and 1.85:1 respectively, whereas CP was more common in females with SR of 0.76:1. Associated malformations (2.89%), involved 29 CP cases, 41 CL and 156 CLP. The frequency of associated malformations in CLP (3.35%) was higher than CL (2.24%) and CP (2.22%) (P < 0.05). Patients with CP or CLP were born less often in the winter than in the summer (P < 0.05). A history of family members having clefts occurred in 6.84% of patients. The proportion of CLP cases (7.56%) was significantly higher than that of CL cases (5.64%) (P < 0.05).</p><p><b>CONCLUSIONS</b>The different types of clefts appeared in the highest proportion in CLP and lowest proportion in CP. Males are more common with CL and CLP and less common with CP. These characteristics are the same as those of other Chinese surveys but different from some European reports.</p>
