Effects of Oral Stimulation Intervention in Newborn Babies with Cri du Chat Syndrome: Single-Subject Research Design.

The purpose of this study is to treat dysphagia in a newborn baby with cri du chat syndrome using an oral stimulation intervention and to examine its effects. The subject of this study was a baby born 2 weeks prematurely. Since birth, his oxygen saturation (SaO2) decreased while feeding, and he had difficulty with mouth feeding. Thus, an NG feeding tube was inserted, and dysphagia treatment was initiated on the sixth day after birth. A baseline phase and an intervention phase were performed using an AB design. The oral stimulation intervention was not performed in the baseline phase, as only nonnutritive sucking training using a rubber pacifier was used during the baseline phase. During the intervention phase, nonnutritive sucking training and oral stimulation intervention were simultaneously conducted. After the intervention period, daily oral milk intake and intake per feeding of the subject noticeably increased. The oxygen saturation while feeding rose over 90% on average, and the baby did not present with hypoxia. The oral stimulation intervention provided prior to feeding resulted in highly positive effects, including induced normal development of the baby, stimulation of his transition from the NG feeding tube to bottle feeding, increased oxygen saturation, and a shortened hospital stay.

Psychomotor Development in Cri du Chat Syndrome: Comparison in Two Italian Cohorts with Different Rehabilitation Methods.

The Cri du Chat syndrome (CdC) is a rare genetic disorder caused by variable size deletions of the short arm of chromosome 5 (5p-). It is well known that home-reared patients show better performances as compared to institutionalised cases, and it was reported that continuous educational intervention can ameliorate their performances. To assess the efficacy of educational intervention and to develop new CdC oriented programs of rehabilitation, we compare the results obtained for many developmental skills in two groups of CdC patients undergoing two different rehabilitation programs. Using data on the development of a group of CdC patients obtained by validated Italian translation for the Denver Developmental Screening Test II, we compared a group of 13 patients undergoing an educational program developed for CdC patients, the Mayer Project (MP), with a second group of 15 cases in whom caring was not specifically oriented. A positive impact of the MP was reported by parents, observing an improvement in social skills obtained, even if no significant differences were observed when the items of the Denver Test are studied. The need for personalized care in CdC patients and the choice of different methods to compare the results are also discussed.

[The Cri du Chat syndrome: a study on the quality of care]. / Sindrome del Cri du Chat: indagine sulla qualità dell' assistenza.

AIM: The Cri du Chat syndrome (SCdC / [OMIM #123450]) is a rare disease characterized by the deletion of the short arm of chromosome 5. The typical clinical features are the cat-like cry, microcephaly, a distinct facial phenotype and a severe psychomotor and mental retardation. The aim of this study was to provide an analysis on the data concerning the life quality and families assistance to whom have a child affected by Cri du Chat syndrome such as: the life's change of parents after the child's birth, the frequency of treatments, the collaboration between family and center of reference. METHODS: We have also analyzed the improvement obtained, the type of school attended, the aide and the time spent at home in postprimary education. Through a questionnaire sent to 100 families, we have been picked up information on 76 patients. RESULTS: These families have to adapt to the reality of a child with a rare genetic disorder for which there are no pharmacological or surgical therapies. CONCLUSION: Therefore, it seems important to give information and tips for dealing with the disease and the early start of rehabilitation and educational therapy.

Inflectional morphology in cri du chat syndrome--a case study.

This study examined morphological skills in a girl with cri du chat syndrome, addressing three questions: (1) To what extent does the subject inflect words? (2) To what extent are words inflected correctly? (3) To what extent do the inflected words reflect productive morphological rules, and to what extent can they be considered to be rote-learned? The study draws on two sources of data: a corpus of spontaneous utterances collected when the subject was 14 years old and her performance on a past tense elicitation test at 11;10 and 16;5. It was found that most inflectional forms in the nominal, verbal, pronominal and adjectival paradigms of the target language were attested in the corpus. These forms were in all but a few instances inflected correctly. The most frequent inflection errors were infinitive for present, past or past participle in verbs and wrong gender in determiners. Furthermore, performance on the elicitation test indicated some knowledge of productive inflectional rules of the target language, despite relatively poor phonetic, phonological and syntactic skills.

The effect of syndrome diagnosis on speech remediation.

On the basis of work reported by colleagues, as well as our own clinical research studies of patients with the aforementioned syndromes, there are now some useful guidelines for appropriate remediation based on accurate initial diagnosis. Still, there is more to be learned about each of these syndromes. Furthermore, they represent but a small sample of a very large total. Recent literature has described the speech patterns of many more syndromes, as well as the genetic aspects of the more common speech and language disorders such as language delay, dyslexia, autism, and stuttering [72-78]. The most common recognizable birth defect is Down syndrome and there is, fortunately, a large body of information detailing the varied language, speech, and hearing aspects [79]. Those of us who work with children with Down syndrome have been alerted to the anticipated receptive and expressive language delays; the conductive and sometimes mixed hearing losses; the hoarse and raucous voices that are probably the result of a combination of anatomic, neurologic, and mucosal variations; the interesting disfluencies, and the amalgam of developmental and deviant articulatory errors. We know that although the tongue protrudes, it is rarely the true macroglossia which we would find in Beckwith syndrome, for example, but rather a hypotonic posture and a logical adaptation to an airway restricted by enlarged tonsils and adenoids and recurrent rhinitis.
