To explore both the early prediction and diagnosis of dysphagia in preterm infants as an important developmental aspect as well as the prevention of respiratory complications, we developed the simple and-easy-to-apply Dysphagia Screening Test for Preterm Infants (DST-PI) to predict supraglottic penetration and subglottic aspiration.
Fifty-two infants were enrolled in a videofluoroscopic swallowing study (VFSS) due to clinical suspicions of dysphagia. Thirteen items related to supraglottic penetration or subglottic aspiration were initially selected from previous studies for the DST-PI. Finally, 7 items were determined by linear logistic regression analysis. Cutoff values, sensitivity, specificity, and the area under the ROC curve (AUC) of the DST-PI for predicting supraglottic penetration or subglottic aspiration were calculated using a ROC curve. For inter-rater reliability, the kappa coefficient was calculated.
Seven items were selected: ‘gestational age,’ ‘history of apnea,’ ‘history of cyanosis during feeding,’ ‘swallowing pattern,’ ‘coughs during or after feeding,’ ‘decreased oxygen saturation within 3 minutes of feeding,’ and ‘voice change after feeding.’ The Spearman correlation coefficient between the DST-PI and the penetration-aspiration scale (PAS) was 0.807 (p<0.001). The sensitivity and specificity at different cutoff values for detecting supraglottic penetration and subglottic aspiration were 96.6% and 76.9% at 3.25, and 88.9% and 75.8% at 6.25, respectively.
The DST-PI is a valid and reliable dysphagia screening test for supraglottic penetration or subglottic aspiration in preterm infants that is easy to apply in a clinical context.

To perform an in depth evaluation of children, and thus provide a systematic method of managing children, who after infantile health screening, were categorized as suspected developmental delay.
78 children referred to the Developmental Delay Clinic of Ilsan Hospital after suspected development delay on infantile health examinations were enrolled. A team comprised of a physiatrist, pediatrician and pediatric psychiatrist examined the patients. Neurological examination, speech and cognitive evaluation were done. Hearing tests and chromosome studies were performed when needed clinically. All referred children completed K-ASQ questionnaires. Final diagnoses were categorized into specific language impairment (SLI), global developmental delay (GDD), intellectual disability (ID), cerebral palsy (CP), motor developmental delay (MD) or autism spectrum disorder (ASD).
72 of the 78 patients were abnormal in the final diagnosis, with a positive predictive value of 92.3%. Thirty (38.4%) of the 78 subjects were diagnosed as GDD, 28 (35.8%) as SLI, 5 (6.4%) as ASD, 9 (12.5%) as MD, and 6 (7.6%) as normal. Forty five of the 78 patients had risk factors related to development, and 18 had a positive family history for developmental delay and/or autistic disorders. The mean number of abnormal domains on the K-ASQ questionnaires were 3.6 for ASD, 2.7 for GDD, 1.8 for SLI and 0.6 for MD. Differences between these numbers were statistically significant (p<0.05).
Because of the high predictive value of the K-ASQ, a detailed evaluation is necessary for children suspected of developmental delay in an infantile health promotion system.

To evaluate concurrent validity between the Korean-Ages and Stages Questionnaires (K-ASQ) and the Denver Developmental Screening Test II (DDST II), and to evaluate the validity of the K-ASQ as a screening tool for detecting developmental delay of Korean children.
A retrospective chart review was done to examine concurrent validity of the screening potentials for developmental delay between the K-ASQ and the DDST II (n=226). We examined validity of the K-ASQ compared with Capute scale (n=141) and Alberta Infant Motor Scale (AIMS) (n=69) as a gold standard of developmental delay. Correlation analysis was used to determine the strength of the associations between tests.
A fair to good strength relationship (k=0.442, p<0.05) was found between the K-ASQ and the DDST II. The test characteristics of the K-ASQ were sensitivity 76.3-90.2%, specificity 62.5-76.5%, positive likelihood ratio (PLR) 2.41-3.40, and negative likelihood ratio (NLR) 0.16-0.32.
Evidence of concurrent validity of the K-ASQ with DDST II was found. K-ASQ can be used for screening of developmental delay.

Objective: This study was designed to evaluate the correlation of periventricular leukomalacia (PVL) on brain MRI and Denver II and Capute developmental test.
Method: Thirty children with PVL on brain MRI showing delayed development were included. The severity of PVL was graded as localized/generalized lesion in three fields; periventricular hyperintensity in T2 weighted image (PVHI in T2WI), reduced volume of cerebral white matter (RV of CWM), ventriculomegaly with periventricular wall irregularity (VM with PVWI). Development quotients were obtained by Denver II and Capute test, and assessed according to the severity of PVL.
Results: Although language, fine motor-adaptive, personal- social scale of Denver II and cognitive-adaptive and clinical linguistic and auditory milestone of Capute test had little correlation with severity of PVL, gross motor developmental scale assessed by Denver II had a certain degree of correlation with severity of PVL which was not significant statistically. The gross motor developmental scale of the nineteen preterm births had a significant correlation with VM with PVWI, but the other developmental scales still had no significant correlation with PVL.
Conclusion: As for the children with delayed development the degree of motor development was a significant predictor of the PVL on brain MRI, but those of language and cognitive development were not. (J Korean Acad Rehab Med 2002; 26: 273-278)
Objective: The purpose of this study was to determine the usefulness of brainstem evoked potential (BAEP) in the diagnosis of cerebellopontine angle (CPA) tumors.
Method: Sixteen subjects in which BAEP study was compatible with CPA tumors were retrospectively reviewed and analyzed the results of BAEP, findings of CT and MRI, and clinical signs.
Result: Thirteen subjects were reviewed and three were lost in follow-up. 1) CPA tumors were confirmed with CT/MRI in 10 subjects and the other 3 patients had other lesions which could be differentiated from CPA tumors clinically. The positive hit rate of BAEP was 76.9% in 13 patients whose findings were compatible with CPA lesion. 2) Of 10 patients with CPA tumor, the tumors were bilateral in 4 patients and unilateral in 6 patients, and the diagnosis of the tumors were vestibular schwannoma in 9 patients and meningioma in 1 patient. 3) The major symptoms of the patients with CPA tumors were hearing loss, tinnitus, dizziness, facial nerve palsy, headache, cerebellar dysfunction, nystagmus, and vertigo. 4) The most common abnormal findings of BAEP in the patients with CPA tumors were increase in the interpeak latency I-III and I-V on the affected side and interpeak latency III-V on the unaffected side.
Conclusion: The BAEP considering clinical correlation is a useful study as a screening test in the diagnosis of CPA tumors because of its high positive hit rate and cost-effectiveness compared with CT/MRI.
Objective: To evaluate the pattern of developmental delay of language and to correlate the language with other developmental areas in cerebral palsy children.
Method: Sequenced Inventory of Communication Development (SICD) was studied in 31 children with cerebral palsy of age ranging from 11 months to 48 months. Korean Denver Developmental Screening Test (DDST) was also performed in 18 children simultaneously.
Results: On SICD, 10 children (32.3%) showed the receptive language delay and 13 children (41.9%) showed the expressive language delay. Among 15 spastic quadriplegic children, 40% showed the delay of receptive language development, 53.3% showed the delay in expressive language development. Among 10 spastic diplegic children, 30% showed the delay of both receptive and expressive language development. One spastic right hemiplegic child showed a delay of expressive language development, but 4 left hemiplegic children showed the normal language development. One hypotonic cerebral palsy child showed a delay of both receptive and expressive language development.
The expressive language was delayed more than the receptive language.
SICD correlated highly with the language sector of DDST. And both SICD and DDST language sectors correlated with the other sectors of DDST (personal-social, fine motor-adaptive, gross motor), especially with the fine motor sector (r=0.912, 0.918, 0.976, p＜0.001).
Conclusion: There is a considerably high incidence of developmental delay of language in cerebral palsy children, especially among spastic quadriplegic children.
The early evaluation and treatment for the developmental delay of language need to be included in a general rehabilitation program for the cerebral palsy children.
Objective: To evaluate the clinical values of the DDST II (Denver Developmental Screening Test, 2nd revision), 99mTc HMPAO brain single photon emission computed tomography (SPECT) findings and brain magnetic resonance imaging (MRI) in the assessment of cerebral palsy children.
Method: Twenty-two children with cerebral palsy were investigated. Four profiles of DDST (II) were summated to a monthly age according to each developmental status. 99mTc HMPAO brain SPECT imagings were analyzed for the calculation of the perfusion defect indices. The clinical severities were scored as mild to severe, and were compared to a motor age of Maryland criteria. The presence of abnormal findings of brain MRI was also checked.
Results: (1) The gross and fine motor profiles of DDST (II) were significantly different between normal and abnormal findings of the brain SPECT in cerebral palsy children. (2) The region of interests ROIs in brain SPECT correlated with many profiles of DDST (II), 1) prefrontal area of the brain SPECT and language profile of DDST (II), 2) premotor area and gross motor/language profile, 3) thalamic area and social-personal profile, 4) basal ganglia area and gross motor/language proflie. respectively. (3) There was no relationship between each profile of DDST (II) and brain MRI findings.
Conclusion: The DDST (II) and Brain SPECT seemes to be more useful than the brain MRI for the functional assessment of cerebral palsy children.
