Introduction. Despite a rather extensive literature on the subject, most research on the nature of infant speech can be characterized as impressionistically descriptive, or anecdotal, or speculative, or some combination thereof. Such studies have by and large ignored the structure, function and natural history of early vocal behaviour, an empirically adequate specification of which is a necessary prerequisite to an understanding of the development of infant vocalizations and of their relationship to later linguistic usage. Likewise, reports have generally failed to recognize the dynamic interactions within the developing organism as a whole, eschewing discussion of concomitant neurophysiological maturation and cognitive growth. While detailed consideration falls beyond the scope of the present paper, some insight into the issues involved may be gained from recent treatises dealing with brain development (Jacobson, 1975), myelogenesis (Lecours, 1975) and the ontogeny of cerebral dominance (Zangwill, 1975). Problems relating to speech input and output requirements in acquisition have been treated by Mattingly (1973), and the interplay of physiological-cognitive factors with respect to early speech perception and production has been critically overviewed by Gilbert (1975). Suffice it to say that until experimental evidence can be adduced, interpreted and properly interwoven into a coherent description, definitive theories on the acquisition and development of speech and language must perforce remain only as desiderata.

A total of 105 children with neonatal transitory hypothyrosis were observed from birth till the age of 3-5 years. Control group consisted of 81 children with normal thyroid function during the neonatal period. Unfavorable perinatal factors (complications of pregnancy and labor, maternal chronic diseases) contributed to the development of transitory hypothyrosis. A history of neonatal transitory hypothyrosis has a negative impact on subsequent physical, nervous, mental, and speech development of children and their health status during the first year of life and in preschool age. An unfavorable individual prognosis as regards further nervous and mental development, made on the basis of an original table of prognostic coefficients, can be sufficient for prescribing thyroid hormone preparations to neonates with transitory hypothyrosis.

Abstract Background Canavan disease (CD, MIM # 271900) is a rare and devastating leukodystrophy of early childhood. To identify clinical features that could serve as endpoints for treatment trials, the clinical course of CD was studied retrospectively and prospectively in 23 CD patients. Results were compared with data of CD patients reported in three prior large series. Kaplan Meier survival analysis including log rank test was performed for pooled data of 82 CD patients (study cohort and literature patients). Results Onset of symptoms was between 0 and 6 months. Psychomotor development of patients was limited to abilities that are usually gained within the first year of life. Macrocephaly became apparent between 4 and 18 months of age. Seizure frequency was highest towards the end of the first decade. Ethnic background was more diverse than in studies previously reported. A CD severity score with assessment of 11 symptoms and abilities was developed. Conclusions Early hallmarks of CD are severe psychomotor disability and macrocephaly that develop within the first 18 months of life. While rare in the first year of life, seizures increase in frequency over time in most patients. CD occurs more frequently outside Ashkenazi Jewish communities than previously reported. Concordance of phenotypes between siblings but not patients with identical ASPA mutations suggest the influence of yet unknown modifiers. A CD severity score may allow for assessment of CD disease severity both retrospectively and prospectively.

Objective. To investigate the natural history of and risk factors for allergic rhinitis in the first 6 years of life. Methods. Parents of 747 healthy children followed from birth completed a questionnaire when the child was 6 years old. Data were obtained regarding physician-diagnosed allergic rhinitis (PDAR), associated symptoms, and age at onset. Risk-factor data were taken from earlier questionnaires, and data regarding immunoglobulin E (IgE) and skin-test reactivity were obtained at age 6. Results. By the age of 6, 42% of children had PDAR. Children whose rhinitis began in the first year of life had more respiratory symptoms at age 6 and were more likely to have a diagnosis of asthma. Early introduction of foods or formula, heavy maternal cigarette smoking in the first year of life, and higher IgE, as well as parental allergic disorders, were associated with early development of rhinitis. Risk factors for PDAR that remained significant in a multivanate model included maternal history of physician-diagnosed allergy (odds ratio: 2.2, 95% confidence interval: 1.35-3.54), asthma in the child (4.06, 2.06-7.99), and IgE greater than 100 IU/mL at age 6 (1.93, 1.18-3.17). The odds for atopic as opposed to nonatopic PDAR were significantly higher only among those with high IgE and those who had dogs. Conclusion. Allergic rhinitis developing in the first years of life is an early manifestation of an atopic predisposition, which may be triggered by early environmental exposures.

PURPOSE: To study the temporal auditory ordering and resolution abilities in children with and without a history of early OME and ROME, as well as to study the responses according to age. METHODS: A total of 59 children were evaluated, and all of them presented pure tone thresholds within the normal range at the time of the conduction of the hearing tests. The children were divided into two groups according to the occurrence of episodes of recurrent otitis media. Then, each group was divided into two subgroups according to age: 7- and 8-year olds, and 9- and 10-year olds. All children were assessed with standard tests of temporal frequency (ordination) and gaps-in-noise (resolution). RESULTS: For the temporal abilities studied, children with a history of otitis media presented significantly lower results compared to the control group. In the frequency pattern test, the correct answers increased with age in both groups. In the identification of silence intervals, the control group showed no change in threshold regarding to age, but this change was present in the group with a history of otitis media. CONCLUSION: Episodes of otitis media with effusion in the first year of life, recurrent and persistent in preschool and school ages, negatively influence the temporal ordering and resolution abilities.

Abstract Lichen striatus (linear lichenoid dermatosis) is an uncommon, self-limited, inflammatory, linear skin condition of unknown origin. The causes of linear distribution are unknown, though the pattern of lichen striatus (LS) mostly follows the lines of Blaschko (BL). The condition most commonly occurs in children between 5 and 15 years of age, usually after the first year of life. We report a 27-year-old, otherwise healthy flight attendant with LS whose diagnosis was based on: the history of sudden appearance and rapid linear spread of lesions; clinical presentation of small pink, coalescing scaly papules without umbilication or Wickham’s striae, linear distribution following one BL down a lower limb to the ankle, with a band broadening into plaque on the left buttock; histology showed some hyperkeratosis, lichenoid dermatitis similar to lichen planus, but with the presence of inflammatory infiltrate in the papillary dermis and also deeper in the perifollicular region. The inflammatory infiltrate consisted mainly of limphocytes, with some melanophages and histiocytes. There is no standard treatment for LS, and it is given for cosmetic or psychological reasons only, as we have done in our patient due to slight pruritus and occupational reasons. With regard to her occupational demands, in order to achieve satisfying results, she was successfully treated with cryotherapy, which she tolerated well, without any side effects. Cryotherapy was performed twice, with a two-week interval. Full resolution was achieved twelve weeks after cryotherapy. In conclusion, we present an adult female who developed lichen striatus suddenly three months after delivery and was successfully treated with cryotherapy.

Decarboxylase Deficiency

AbstractAromatic L-amino acid decarboxylase (AADC) deficiency is a rare, autosomal recessive inborn error of metabolism in which several neurotransmitters including serotonin, dopamine, norepinephrine and epinephrine are deficient. Symptoms typically appear in the first year of life and include oculogyric crises and dystonia, hypotonia, and global developmental delay. Dystonia is of particular concern as a dystonic storm can ensue leading to rhabdomyolysis. Rhabdomyolysis can become life-threating and therefore its recognition and prompt management is of significant importance. Here we present two cases of patients with AADC deficiency and a history of dystonic crisis causing rhabdomyolysis. We hypothesize that in addition to the hypodopaminergic, a hypercholinergic state is contributing to the pathophysiology of dystonia in AADC deficiency, as well as to the associated rhabdomyolysis. We were able to prevent rhabdomyolysis in both patients with using Dantrolene and we suggest using a trial of this medication in cases of sustained dystonic crisis in AADC deficiency patients.

Respiratory Microbiota

ABSTRACTBackground: Postnatal development of the microbiota in early life influences immunity, metabolism, neurodevelopment and long-term infant health. Microbiome development occurs at multiple body sites, each with distinct community compositions and functions. Associations between microbiota at multiple sites represent an unexplored influence on the infant microbiome. Here, we examined co-occurrence patterns of gut and respiratory microbiota in pre- and full-term infants over the first year of life, a period critical to neonatal development and risk of respiratory diseases.Results: Gut and respiratory microbiota collected as longitudinal rectal, throat and nasal samples from 38 pre-term and 44 full-term infants were first clustered into community state types (CSTs) on the basis of their composition. Multiple methods were used to relate the occurrence of CSTs to several measures of infant maturity, including gestational age (GA) at birth, week of life (WOL), and post menstrual age (PMA: equal to GA plus WOL). Manifestation of CSTs followed one of three patterns with respect to infant maturity. First, chronological: independent of infant maturity (GA) at birth, and strongly associated with post-natal age (WOL). Second, idiosyncratic: primarily dependent on maturity (GA) at birth, with persistent differences in CST occurrence between pre- and full-term infants through the first year of life. Third, convergent: CSTs appear earlier in infants with greater maturity (GA) at birth, but after a sufficient post-natal interval their occurrence in pre-term infants reaches parity with full-term infants. The composition of CSTs was highly dissimilar between different body sites, but the CST of any one body site was highly predictive of the CSTs at other body sites. There were significant associations between the abundance of individual taxa at each body site and the CSTs of the other body sites, which persisted after stringent control for the non-linear effects of infant maturity. Significant canonical correlations exist between the microbiota composition at each pair of body sites, with the strongest correlations between more proximal locations.Conclusion: Cross-body site associations of developing infant microbiota suggest the importance of research and clinical practices that focus on dynamic interactions between multiple microbial communities to elucidate and promote systemic microbiota development.

The Relationship

The variability of a child’s voice onset time (VOT) decreases during development as they learn to coordinate upper vocal tract and laryngeal articulatory gestures. Yet, little is known about the relationship between VOT and other early motor tasks. The aims of this study were to evaluate the relationship between infant vocalization and another early oromotor task, non-nutritive suck (NNS). Twenty-five full-term infants (11 male, 14 female) completed this study. NNS was measured with a customized pacifier at 3 months to evaluate this early reflex. Measures of mean VOT and variability of VOT (measured via coefficient of variation) were collected from 12-month-old infants using a Language Environmental Analysis device. Variability of VOTs at 12 months was significantly related to NNS measures at 3-months. Increased VOT variability was primarily driven by increased NNS intraburst frequency and increased NNS burst duration. There were no relationships between average VOT or range of VOT and NNS measures. Findings from this pilot study indicate a relationship between NNS measures of intraburst frequency and burst duration and VOT variability. Infants with increased NNS intraburst frequency and NNS burst duration had increased VOT variability, suggesting a relationship between the development of VOT and NNS in the first year of life. Future work is needed to continue to examine the relationship between these early oromotor actions and to evaluate how this may impact later speech development.
