Iatrogenic pseudoaneurysms are extremely rare in children. Conventional management of pseudoaneurysms in adults has included surgical repair, ultrasound-guided compression, and more recently, endovascular embolization. However, in infants and children, there is little information regarding the applicability of such treatment modalities, which have been effective in adults, because of its rarity. Here, we present the case of a 6-month-old infant who developed a postprocedural pseudoaneurysm of the external iliac artery, which was successfully treated with ultrasound-guided percutaneous thrombin injection.

The purpose of this study is to investigate the features of Korean infants' vocalizations according to the stages models. A total 88 infants, whose ages range from 1 to 18 months, participated in this study. This age is a critical period for vocal development. However, the study of infants' vocalizations has typically focused on children over the age of two. Because of restrictions related to the study of younger infants, from birth to the age of two, it is usually difficult to investigate what are the major features of their vocal development. Therefore, this study provides documentation and analysis of the features of infant vocalization and their vocal development stages. The results shows that the stages model of Oller & Lynch (1992) might be adapted for Korean infants' vocal development. Furthermore, the features of the infants' vocalization are not linearly appeared one stage to the next stage, but are overlapped (Koopmans-van Beinum & van der Stelt, 1986; Nathani et al., 2006; Oller, 1980; Stark, 1980; Vihman, 1996).

Plain X-ray radiographs are the first line of investigation taken in the diagnosis of abdominal pathology and are considered an important diagnostic tool to provide guidelines for further imaging studies and comprehensive therapeutic management. Although most abdominal pathology demonstrates non-specific radiologic findings, the plain abdominal radiography is very useful in specific diseases, including certain gastrointestinal anomalies. This review provides image findings of normal plain abdominal radiography and some common abdominal pathology in infants and children.

The purpose of this study is to investigate to what extent and how the infant's Object Attachment occurs. For this purpose, 28 mothers with their infants showing or having shown this phenomenon were interviewed. They were selected by the whole scale smpling method from 310 household -wives living at a delux Apt. in Seoul. The results are summarized as follows : 1. About 27% of the infants aged between 6 months and 6 years turned out to show this phenomenon. 2. Qulits, bed clothes, pillows and blankets, which infants have been closely contacted since their babyhood, were the major source of attachment objects. In general, these objects were proved to have soft, wasm, smooth, and glassy tactile sensation. 3.This phenomenon, in average, appeared since 13 months after birth, About 50% of the whole began to show this phenomenon between 9 and 14 month after birth. 4. Half of the infants didn't show a change of attachment strength, but as for the other half, the attachment strength increased after one year of age, and decreased after three years of age, as the social period commenced. 5. Infants needed attachment objects especially when they were driven by sleep, sense of emptiness, and monotonous or boring feeling. 6. There were little difference between Object Attachment behavior and motherinfant attachment behavior except "babbling", "using her as a base for exploration". Those behaviors did not appear in Object Attachment. 7. mothers said that their children's attachment objects played the role of substitute mother, pacificater, warmer, friend , etc. And they attributed this phenomenon's appearance to lack their physical contact with, ocnstant and warm care toward, their children or bottle feeding.

Objectives: The purpose of this study was to investigate the factors affecting the use of oral hygiene products in infants. Methods: From October 2015 to December 2015, astructured questionnaire survey was conducted for infants and parents about the infants' oral hygiene product use from 0 to 4 years of age in Seoul and other metropolitan areas. Results: The use of oral tissues for infants and children was more frequent in infants, with less than four uses of oral tissues per 10 infants. The overall amount of toothpaste usage among infants was lower than those of infants whose parents are high school or college graduates. The number of oral tissues used per infant per week was less among infants who sucked less than 4 times per 10 infants. The frequency of use of infant mouthwash per week in every 10 infants was less than those who swallow mouthwash less than once. The number of mouth rinses after the use of oral tissues for infants was high in boys, and the number of infants who sucked oral tissues was less than 4 times when used 10 times. The number of mouth rinses after the use of toothpaste was less for infants with college-graduate parents. The factors affecting the number of mouth rinsings after using oral tissues for infants were gender and sucking frequency. Conclusions: In this study, the oral hygiene products for infants were found to differ and affect the usage, the frequency of use, and the number of mouth rinses according to the general characteristics of infants' and parents and the use of oral hygiene products.

Two sub-standies were conducted to analyze attachment related variables in infants and characteristics of maternal behavior. The first study investigated the relationships among attachment related variables in infants. The sample consisted of 58 pairs of 11- to 13- months-old infants and their mothers. A significant relationship was found among attachment security, infant temperament and maternal sensitivity. There were differences between security scores of the easy and difficult infants. Securely attached infants were rated as easier temperamentally than insecurely attached infants. The second study analyze maternal behavior characteristics. Subjects were this 30 mothers whose children were between the ages of 2 months and 24 months. The results identified four types of maternal behaviors. This study suggests different method of assessing subjective attributes of individuals by introducing Q-methods to the field of child development.

Children are the most nutrition sensitive sub-group of a population. The nutritional status of children should be especially emphasized at all levels. This study was performed to investigate the current status, trend, and influencing factors to malnutrition of infants and children in China. The study was mainly based on the China Health and Nutrition Survey which is a longitudinal study conducted in 8 provinces and the data on growth of children under 7 years of age in 9 cities in China. The result of this study showed that one fifth of the children under 5 years of age are still suffering from stunted growth and one tenth suffering from underweight. The nutrition intervention on children under 2 years of age, especially on those under 18 months should be emphasized. Better supplementary food can improve the nutritional status to decrease the prevalence of stunted children. Therefore, the development of supplementary food should be the priority and should be emphasized with breastfeeding.

In infants and young children, bedtime problems and night waking are common and the main presentations of insomnia. Poor sleep may critically impact the daytime functioning and mood of the child and their caregivers. A comprehensive sleep history, a sleep diary/log, and the BEARS (Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep, and Sleep-disordered breathing) sleep screen are useful for diagnosing sleep problems in young children. Behavioral therapies for this type of insomnia include extinction, bedtime fading with positive routines, and scheduled awakening. Previous studies of behavioral interventions for young children showed significant improvements in sleep-onset latency, night waking frequency, and night waking duration. Parent education about their child's sleep, bedtime routines, and sleep hygiene is essential for treatment.

We frequently encounter newborn infants with thrombocytosis in the neonatal intensive care unit. However, neonatal thrombocytosis is not yet fully understood. Thrombocytosis is more frequently identified in newborns and young infants, notably more often in those younger than 2 years than in older children or adults. The production of megakaryocytes (megakaryopoiesis) and platelets (thrombopoiesis) is mainly regulated by thrombopoietin (TPO). Increased TPO levels during infection or inflammation can stimulate megakaryopoiesis, resulting in thrombopoiesis. TPO concentrations are higher in newborn infants than in adults. Levels increase after birth, peak on the second day after birth, and start decreasing at 1 month of age. Initial platelet counts at birth increase with gestational age. Thus, preterm infants have lower initial platelet counts at birth than late-preterm or term infants. Postnatal thrombocytosis is more frequently observed in preterm infants than in term infants. A high TPO concentration and low TPO receptor expression on platelets leading to elevated plasma-free TPO, increased sensitivity of megakaryocyte precursor cells to TPO, a decreased red blood cell count, and immaturity of platelet regulation are speculated to induce thrombocytosis in preterm infants. Thrombocytosis in newborn infants is considered a reactive process (secondary thrombocytosis) following infection, acute/chronic inflammation, or anemia. Thrombocytosis in newborn infants is benign, resolves spontaneously, and, unlike in adults, is rarely associated with hemorrhagic and thromboembolic complications.
