The purpose of this review is to present the basic concepts of attachment theory and temperament traits and to discuss the integration of these concepts into parenting practices. Attachment is a basic human need for a close and intimate relationship between infants and their caregivers. Responsive and contingent parenting produces securely attached children who show more curiosity, self-reliance, and independence. Securely attached children also tend to become more resilient and competent adults. In contrast, those who do not experience a secure attachment with their caregivers may have difficulty getting along with others and be unable to develop a sense of confidence or trust in others. Children who are slow to adjust or are shy or irritable are likely to experience conflict with their parents and are likely to receive less parental acceptance or encouragement, which can make the children feel inadequate or unworthy. However, the influence of children's temperament or other attributes may be mitigated if parents adjust their caregiving behaviors to better fit the needs of the particular child. Reflecting on these arguments and our childhood relationships with our own parents can help us develop the skills needed to provide effective guidance and nurturance.

I report a case of extremely low birth weight infant, who presented central diabetes insipidus associated with cytomegalovirus infection. His brain magnetic resonance imaging showed a flattened pituitary gland, and demonstrated a lack of posterior pituitary hyperintensity. It successfully managed with oral desmopressin (Minirin(R)) and persisted beyond the resolving of symptomatic cytomegalovirus infection.

Bronchial injury is a rare and serious complication of endotracheal intubation in neonates. Bronchial perforation following tracheal intubation causes a high-volume air leak mimicking pneumothorax and pneumomediastinum, and it may result in intraventricular hemorrhage, mediastinitis and sepsis. I report my experience of diagnosing a main bronchial perforation in an extremely low birth weight infant, who had a high-volume air leak following tracheal intubation, which persisted after chest tube insertion.

Transient myeloproliferative disorder (TMD) is similar to congenital leukemia, with leukocytosis, increased peripheral blast cells, and hepatomegaly in the neonatal period. Although TMD occurs only in patients with Down syndrome and trisomy 21 mosaicism, there have been reports of congenital leukemia with trisomy 21 limited to hematopoietic cells showing spontaneous resolution. We identified trisomy 21 in the leukemic cells in a patient with congenital leukemia. As there was no other gene abnormality, we stopped chemotherapy, and the disease resolved spontaneously. We reviewed the cases of clonal trisomy 21 TMD and found that their clinical features were similar to those of TDM associated with Down syndrome. In conclusion, in a phenotypically normal patient with suspected congenital leukemia, it is necessary to confirm the presence of 21 trisomy. If the neonate has only trisomy 21 without other gene abnormalities, intensive chemotherapy may not be required.

PURPOSE: Preterm infants frequently require red blood cell (RBC) transfusions in neonatal intensive care units (NICU). Storage RBCs undergo many changes during storage periods. We aimed to compare the hemoglobin (Hb) correction effect according to the period of RBC storage and investigate the factors influencing Hb correction. METHODS: This retrospective study reviewed the medical records of 289 patients who received RBC transfusion more than once in the NICU of Kosin University Gospel Hospital between February 2006 and March 2016. The subjects were classified into two storage groups: short-term (≤7 days, n=88) and long-term (>7 days, n=201), according to the period of RBC storage. We checked Hb levels by complete blood cell count tests conducted within 2 days before and 5 to 9 days after the first transfusion. We compared the Hb difference between the two groups and analyzed the factors influencing Hb correction. RESULTS: Excluding the use of an invasive ventilator, there was no significant difference between the two groups in terms of clinical characteristics. There was no significant difference in the Hb correction effect between the two groups (P=0.537). Birth weight greater than 1,500 g, higher weight at transfusion, and larger volume of transfusion were significant prognostic factors affecting greater changes in Hb. In addition, surgery experience, higher Hb level at transfusion, and additional blood tests were found to be significantly associated with less changes in Hb. CONCLUSION: The RBC storage period did not affect the Hb correction effect. The Hb correction effect may be diminished in infants with lower birth weight and lower weight at transfusion under unstable clinical conditions.

Background: Locomotor activity in mice may have an ultradian rest-activity rhythm. However, to date, no study has shown how locomotor activity can be explained statistically using fitted cosine curves. Therefore, this study explored whether the ultradian rhythm of locomotor activity in mice could be analyzed using cosine fitting analysis. Methods: The locomotor activity of 20 male mice under a 12/12-hour dark/light cycle for 2 days was fitted to a cosine function to obtain the best fit. The mean absolute error (MAE) values were used to determine the explanatory power of the calculated cosine model for locomotor activity. The cosine fitting analysis was performed using R statistical software (version 4.1.1). Results: The mean MAE was 0.2944, whereas the mean MAE for integrating the individual analyses in the two experimental groups was 0.3284. The periods of the estimated ultradian rest-activity rhythm ranged from 1.602 to 4.168 hours. Conclusions These results suggest that locomotor activity data reflect an ultradian rhythm better than a circadian rhythm. Locomotor activity can be statistically fitted to a cosine curve under well-controlled conditions. In the future, it will be necessary to explore whether this cosine-fitting analysis can be used to analyze ultradian rhythms under different experimental conditions.

PURPOSE: Infectious ileocecitis is an infection confined to the ileocecal area and one of the most common causes of pediatric abdominal pain. This study was performed to demonstrate the clinical features of infectious ileocecitis in children. METHODS: The medical records and radiologic findings of 37 patients with ileocecitis diagnosed by ultrasonography and/or computed tomography, who were admitted to Pusan National University Hospital from January 2004 and July 2008, were reviewed retrospectively. Viral gastroenteritis and secondary ileocecitis were excluded. RESULTS: The mean age of the patients was 4.8+/-3.4 years. One-half of the patients were preschool children. The chief complaint was abdominal pain (75.7%), diarrhea (10.8%), and vomiting (8.1%). Accompanying symptoms were fever (56.8%), vomiting (21.6%), and diarrhea (16.2%). The mean duration of abdominal pain, fever, diarrhea, and vomiting was 3.8+/-2.1, 3.0+/-1.9, 3.4+/-1.9, and 2.4+/-2.3 days, respectively. The frequency of diarrhea and vomiting was 5.8+/-2.2 and 4.0+/-2.8 per day, respectively. Diagnosis was made by abdominal ultrasonography in 22 patients (59.5%), abdominal CT in 2 patients (5.4%), and both modalities in 13 patients (35.1%). Besides the radiologic finding of thickening of the bowel wall, mesenteric lymphadenitis (59.5%), ascites (5.4%), and both mesenteric lymphadenitis and ascites (16.2%) were revealed. The mean duration of illness was 7.5+/-5.0 days. There were no specific laboratory findings, and culture studies with stool or blood were negative. All of the patients recovered completely without specific treatment. CONCLUSION: Infectious ileocecitis has acute appendicitis-mimicking symptoms, but is self-limited within a few days, thus unnecessary treatment and work-up is avoided. However, distinguishing infectious ileocecitis from appendicitis, inflammatory bowel disease, and mesenteric lymphadenitis is important.

Preterm ovarian hyperstimulation syndrome (POHS) is characterized by swelling of the vulva and hypogastrium, elevated estradiol and gonadotropin levels, and multiple ovarian follicular cysts in premature baby girls. We report a case of POHS with a review of the literature. The patient presented with swelling of the clitoral hood, and the labia majora and minora. We confirmed multiple ovarian cysts, as well as elevated estradiol and lutenizing hormone levels by performing pelvic ultrasound and laboratory tests. The symptoms resolved gradually and spontaneously.
