ABSTRACT

Background@#Human breast milk is essential and provides irreplaceable nutrients for early humans. However, breastfeeding is not easy for various reasons in medical institution environments. Therefore, in order to improve the breastfeeding environment, we investigated the difficult reality of breastfeeding through questionnaire responses from medical institution workers. @*Methods@#A survey was conducted among 179 medical institution workers with experience in childbirth within the last five years. The survey results of 175 people were analyzed, with incoherent answers excluded. @*Results@#Of the 175 people surveyed, a total of 108 people (61.7%) worked during the day, and 33 people (18.9%) worked in three shifts. Among 133 mothers who stayed with their babies in the same nursing room, 111 (93.3%) kept breastfeeding for more than a month, but among those who stayed apart, only 10 (71.4%) continued breastfeeding for more than a month (P = 0.024). Ninety-five (88.0%) of daytime workers, 32 (94.1%) two-shift workers, and 33 (100%) three-shift workers continued breastfeeding for more than a month (P = 0.026). Workers in general hospitals tended to breastfeed for significantly longer than those that worked in tertiary hospitals (P = 0.003). A difference was also noted between occupation categories (P = 0.019), but a more significant difference was found in the comparison between nurses and doctors (P = 0.012). Longer breastfeeding periods were noted when mothers worked three shifts (P = 0.037). Depending on the period planned for breastfeeding prior to childbirth, the actual breastfeeding maintenance period after birth showed a significant difference (P = 0.002). Of 112 mothers who responded to the question regarding difficulties in breastfeeding after returning to work, 87 (77.7%) mentioned a lack of time caused by being busy at work, 82 (73.2%) mentioned the need for places and appropriate circumstances. @*Conclusion@#In medical institutions, it is recommended that environmental improvements in medical institutions, the implementation of supporting policies, and the provision of specialized education on breastfeeding are necessary to promote breastfeeding.

ABSTRACT

Renal tubular dysgenesis (RTD) is a rare fatal disorder in which there is poor development of proximal tubules, leading to oligohydramnios and the Potter sequences. RTD occurs secondary to renin-angiotensin system (RAS) blockade during the early stages of fetal development or due to autosomal recessive mutation of genes in the RAS pathway. A boy born at 33+1 weeks due to cord prolapse was found to be anuric and hypotensive. Pregnancy was complicated by severe oligohydramnios from gestational age 28+4 weeks. Abdominal sonography revealed diffuse globular enlargement of both kidneys with increased cortical parenchymal echogenicity. Infantogram showed a narrow thoracic cage and skull X-ray showed large fontanelles and wide sutures suggestive of ossification delay. Basal plasma renin activity was markedly elevated and angiotensin-converting enzyme was undetectable. Despite adequate use of medications, peritoneal dialysis, and respiratory support, he did not recover and expired on the 23rd day of life. At first, autosomal recessive polycystic kidney disease was suspected, but severe oligohydramnios along with refractory hypotension, anuria, skull ossification delay and high renin levels made RTD suspicious. ACE gene analysis revealed compound heterozygous pathogenic variations of c.1454.dupC in exon 9 and c.2141dupA in exon 14, confirming RTD. Based on our findings, we propose that, although rare, RTD should be suspected in patients with severe oligohydramnios and refractory hypotension.

ABSTRACT

Clinicians often have difficulties diagnosing patients with subtle phenotypes of Noonan syndrome phenotypes. Facial recognition technology can help in the identification of several genetic syndromes with facial dysmorphic features, especially those with mild or atypical phenotypes. A patient visited our clinic at 5 years of age with short stature. She was administered growth hormone treatment for 6 years, but her growth curve was still below the 3rd percentile. She and her mother had wide-spaced eyes and short stature, but there were no other remarkable features of a genetic syndrome. We analyzed their photographs using a smartphone facial recognition application. The results suggested Noonan syndrome; therefore, we performed targeted next-generation sequencing of genes associated with short stature. The results showed that they had a mutation on the PTPN11 gene known as the pathogenic mutation of Noonan syndrome. Facial recognition technology can help in the diagnosis of Noonan syndrome and other genetic syndromes, especially in patients with mild phenotypes.

ABSTRACT

PURPOSE: Many studies have reported associations of early postnatal growth failure in preterm infants with several morbidities. However, the risk factors for postnatal weight loss (PWL) in late preterm infants have not been identified. We investigated the independentrisk factors for PWL in late preterm infants.METHODS: This was a retrospective cohort study. We enrolled 369 late preterm infants born at 34⁺⁰ to 36⁺⁶ weeks gestational age who were admitted to the Soonchunhyang University Cheonan Hospital between 2015 and 2017. PWL% was calculated as (birth weight–lowest weight)/birth weight×100. The infants were classified into lower (< 5%) and higher (≥10%) PWL% groups by propensity score matching for gestational age, sex, and birth weight. Perinatal risk factors were analyzed using multivariable logistic regression.RESULTS: The lower and higher PWL% groups included 62 and 31 infants, respectively. Antenatal steroids administered within 1 week before birth (odds ratio [OR], 3.26; 95% confidence interval [CI], 1.015 to 10.465; P=0.047), lower total calorie intake during days 1 to 7 (OR, 0.98; 95% CI, 0.977 to 0.999; P=0.027), and phototherapy (OR, 5.28; 95% CI, 1.327 to 21.024; P=0.018) were independent risk factors for the higher PWL%.CONCLUSION: Further studies are needed to identify the risk factors that cause high PWL% according to gestational age and short- and long-term morbidities based on the degree of PWL.

ABSTRACT

OBJECTIVE: The pathophysiology of necrotizing enterocolitis (NEC) is incompletely understood. There were some reports that the pathogenesis of NEC involves intrauterine process and infants with fulminant NEC had low lymphocyte count. Thus, we investigated complete blood count (CBC) parameters of infants at birth and their mothers near delivery. METHODS: We retrospectively reviewed the medical records of NEC patients and controls. The CBC parameters were compared between infants with NEC (modified Bell's criteria stage > or =Ia, n=82) and controls matched for gestational age, birth weight, gender, and race (n=169). The blood test findings were obtained from infants within the first 2 hours of life and from mothers as the latest one before delivery. RESULTS: Statistically different findings at birth were found in NEC infants; red cell distribution width (RDW) and basophil count. In the multiple logistic regression analysis after adjustment for gestational age, birth weight, and gender, several infantile independent risk factors were identified; basophil count <40/microL (odds ratio [OR], 4.60; 95% confidence interval [CI], 2.18 to 9.73; P<0.001) and low RDW (OR, 7.15; 95% CI, 2.93 to 17.41; P<0.001). CONCLUSION: We found that NEC was associated with low infantile RDW and basophil count at birth. These findings might support roles of red blood cell and basophil in the pathogenesis of NEC, which might predict development of NEC with neonatal findings at birth.

ABSTRACT

OBJECTIVE: Necrotizing pneumonia (NP) is a severe complication of lobar pneumonia caused by various pathogens. The immunopathogenesis and clinical characteristics of NP in children are not clearly understood. We wanted to evaluate the clinical characteristics and suggest in part the immunopathogenesis of NP. METHODS: We reviewed retrospectively the medical charts and radiographic materials of eight patients with NP, who were diagnosed by chest radiography and chest computed tomography at the Department of Pediatrics, Soonchunhyang University Hospitals at Cheonan and Bucheon from January 2002 to December 2011. RESULTS: They were previously healthy, 2.1 to 4.6 years of ages (mean, 2.8+/-1.0 years) and three boys and five girls. All of them had pleural effusion. Five patients had pneumonic consolidations in right upper lung field. Three patients had pneumatocele. They developed leukocytosis (mean, 19,400+/-6,400/mm3), higher C-reactive protein level (mean, 25.1+/-8.0 mg/dL). The etiologic agents were revealed in two patients; Streptococcus pneumonia (S. pneumonia) was revealed in one patient and S. pneumonia and Mycoplasma pneumonia in the other patient. Three patients were treated with additional intravenous immunoglobulin. Clinical improvement was prolonged: fever lasted 10 to 23 days, and length of hospitalization was 15 to 36 days. NP or pneumatocele were completely resolved on the follow-up radiographic studies in all of the patients. CONCLUSION: Although the previously healthy young children with NP had protracted clinical course, they recovered without any problematic sequelae. Our results suggest that the immunopathogenesis of NP in children may be associated with the exaggerated immune reaction of the host to insults from initial bacterial infections, rather than the pathogen-induced cytopathies.

ABSTRACT

OBJECTIVE: It is difficult to make a distinction between acute pyelonephritis and lower urinary tract infection due to nonspecific clinical symptoms and laboratory findings. We measured the spot urine beta2-microglobulin in children with urinary tract infection (UTI) to distinguish between acute pyelonephritis and lower UTI. We compared the accuracy of urine beta2-microglobulin measurement with other inflammatory markers. METHODS: We studied 83 children (mean, 86+/-44.9 months) who suspected of having UTI. Leukocyte counts, erythrocyte sedimentation rates (ESR) and C-reactive protein (CRP), beta2-microglobulin were measured. Renal parenchymal involvement was evaluated by 99mTc dimercaptosuccinic acid scintigraphy in the first 7 days after admission. beta2-microglobulin was measured by radioimmunoassay. RESULTS: Urine beta2-microglobulin values were correlated with the presence of renal defects in children with UTI (n=22) (0.98+/-0.24 microg/mL, P<0.05). Using a cutoff of 0.4 microg/mL for spot urine beta2-microglobulin and 20 mm/hr for ESR, 2.6 mg/L for CRP, sensitivity and specificity between UTI with and without renal involvement were 78.7% and 90.1% for spot urine beta2-microglobulin, 77.2% and 90.1% for spot urine beta2-microglobulin/creatinine (Cr), 77.2%, 68.8% for ESR, 86.3%, 68.8% for CRP, respectively. Positive and negative predictive values were 72.7%, 90.1% for spot urine beta2-microglobulin, 73.9% and 91.6% for spot urine beta2-microglobulin/Cr, and 57.5%, 94% for CRP, respectively. CONCLUSION: In febrile UTI, spot urine beta2-microglobulin and beta2-microglobulin/Cr values were more specific than CRP, ESR, and leukocyte count for determine the renal defects.
