Holoprosencephaly (HPE) is a rare congenital disorder characterized by the incomplete separation of the prosencephalon. The clinical spectrum of HPE depends on the subtypes observed on imaging, which includes lobar, semilobar, and alobar variants. Cyclopia, the most severe form of alobar HPE, is typically associated with early postnatal death within a few days. We report the case of a female infant was born at 38 weeks and 6 days of gestation, weighing 2,410 g, to a 39-year-old mother via vaginal delivery. She was the second baby of dichorionic-diamniotic twins. The neonate was born with multiple defects including facial anomalies such as cyclopia and arrhinia and was diagnosed with alobar HPE with cyclopia. This condition was suspected prenatally at 17 weeks of gestation and confirmed postnatally using brain magnetic resonance imaging. The cause of death in our patient was aspiration pneumonia with aggravated central apnea, and she survived for 8 months (240 days) with comfort care alone, without aggressive life support. This is the first report of an infant with alobar HPE, cyclopia, and arrhinia surviving for 240 days with only comfort care, marking the longest documented survival for this typically lethal condition without invasive interventions.

Background:
Despite the popularity of the NeoBase 2 Non-derivatized MSMS assay (PerkinElmer, Turku, Finland), there are no reports of its comprehensive evaluation, including the ability to distinguish transient tyrosinemia of the newborn (TTN) from tyrosinemia type 1 (TYR 1) using succinylacetone (SUAC). No newborn screening (NBS) cutoffs for preterm neonates in the Korean population have been suggested. We evaluated the NeoBase 2 assay and identified analytes requiring different cutoffs in preterm neonates.
Methods:
Residual NBS dried blood spot samples and proficiency testing (PT) materials of the Newborn Screening Quality Assurance Program and the Korean Association of External Quality Assessment Service were used. Precision, accuracy, limit of detection (LOD), lower limit of quantification (LLOQ), linearity, recovery, carryover, and performance of SUAC were evaluated. Cutoffs were determined, and analytes requiring different cutoffs in preterm neonates were investigated.
Results:
Mean CVs for within-run and between-day precision were within 15%. Accuracy analysis indicated high agreement with in-house derivatized assay results and results of other PT participants. All analytes demonstrated acceptable LOD, LLOQ, and linearity. Recoveries were acceptable, except for SUAC. Carryover was negligible. Cutoffs were established for all analytes; Tyr, adenosine, and C20:0-lysophosphatidylcholine required different cutoffs in preterm neonates. Differential diagnosis of TYR 1 and TTN was successful with simultaneous Tyr and SUAC measurement.
Conclusions
The NeoBase 2 assay demonstrated satisfactory performance. The additional analytes provide a wider diagnostic coverage, and the simultaneous measurement of Tyr and SUAC is efficient in excluding TYR 1. The new cutoffs for preterm neonates may decrease false-positive rates, without compromising diagnostic sensitivity.

Infantile cortical hyperostosis, or Caffey's disease, usually presents with typical radiological features of soft tissue swelling and cortical thickening of the underlying bone. The disease can be fatal when it presents antenatally, especially before a gestational age of 35 weeks. This fatal, premature form of the disease is known to occur in various ethnic groups around the globe, and approximately 30 cases have been reported in English literature. This paper is unique in that it is the first paper to report a lethal form of prenatal-type infantile cortical hyperostosis diagnosed in South Korea. Born at gestational age of 27 weeks and 4 days, the patient had typical features of polyhydramnios, anasarca, hyperostosis of multiple bones, micrognathia, pulmonary hypoplasia, and hepatomegaly. The patient was hypotonic, and due to pulmonary hypoplasia and persistent pulmonary hypertension, had to be supported with high frequency ventilation throughout the entire hospital course. Due to the disease entity itself, as well as prolonged parenteral nutrition, liver failure progressed, and the patient expired on day 38 when uncontrolled septic shock was superimposed. The chromosome karyotype of the patient was normal, 46, XX, and COL1A1 gene mutation was not detected.

BACKGROUND: S100A8 and S100A9 have been gaining recognition for modulating tumor growthand metastasis. This study aimed at evaluating the clinical significance of S100A8 and S100A9 innon-small cell lung cancer (NSCLC). METHODS: We analyzed the relationship between S100A8and S100A9 expressions, clinicopathological characteristics, and prognostic significance in tumorcells and peritumoral inflammatory cells. RESULTS: The positive staining of S100A8 in tumorcells was significantly increased in male (p < .001), smoker (p = .034), surgical method other thanlobectomy (p = .024), squamous cell carcinoma (SQCC) (p < .001) and higher TNM stage (p = .022)compared with female, non-smoker, lobectomy, adenocarcinoma (ADC), and lower stage. Theproportion of tumor cells stained for S100A8 was related to histologic type (p < .001) and patientsex (p = .027). The proportion of inflammatory cells stained for S100A8 was correlated with patientage (p = .022), whereas the proportion of inflammatory cells stained for S100A9 was correlatedwith patient sex (p < .001) and smoking history (p = .031). Moreover, positive staining in tumorcells, more than 50% of the tumor cells stained and less than 30% of the inflammatory cellsstained for S100A8 and S100A9 suggested a tendency towards increased survivability in SQCCbut towards decreased survivability in ADC. CONCLUSIONS: S100A8 and S100A9 expressions might be potential prognostic markers in patients with NSCLC.

BACKGROUND: To investigate the incidence of surgical intervention in very low birth weight (VLBW) infants and the impact of surgery on neurodevelopmental outcomes at corrected ages (CAs) of 18–24 months, using data from the Korean Neonatal Network (KNN). METHODS: Data from 7,885 VLBW infants who were born and registered with the KNN between 2013 to 2016 were analyzed in this study. The incidences of various surgical interventions and related morbidities were analyzed. Long-term neurodevelopmental outcomes at CAs of 18–24 months were compared between infants (born during 2013 to 2015, n = 3,777) with and without surgery. RESULTS: A total of 1,509 out of 7,885 (19.1%) infants received surgical interventions during neonatal intensive care unit (NICU) hospitalization. Surgical ligation of patent ductus arteriosus (n = 840) was most frequently performed, followed by laser therapy for retinopathy of prematurity and laparotomy due to intestinal perforation. Infants who underwent surgery had higher mortality rates and greater neurodevelopmental impairment than infants who did not undergo surgery (P value < 0.01, both). On multivariate analysis, single or multiple surgeries increased the risk of neurodevelopmental impairment compared to no surgery with adjusted odds ratios (ORs) of 1.6 with 95% confidence interval (CI) of 1.1–2.6 and 2.3 with 95% CI of 1.1–4.9. CONCLUSION: Approximately one fifth of VLBW infants underwent one or more surgical interventions during NICU hospitalization. The impact of surgical intervention on long-term neurodevelopmental outcomes was sustained over a follow-up of CA 18–24 months. Infants with multiple surgeries had an increased risk of neurodevelopmental impairment compared to infants with single surgeries or no surgeries after adjustment for possible confounders.

Archives of Craniofacial Surgery 2019;20(6):397-400
Frontonasal dysplasia is an uncommon congenital anomaly with diverse clinical phenotypes and highly variable clinical characteristics, including hypertelorism, a broad nasal root, median facial cleft, a missing or underdeveloped nasal tip, and a widow's peak hairline. Frontonasal dysplasia is mostly inherited and caused by the ALX genes (ALX1, ALX3, and ALX4). We report a rare case of a frontonasal dysplasia patient with mild hypertelorism, a broad nasal root, an underdeveloped nasal tip, an accessory nasal tag, and a widow's peak. We used soft tissue re-draping to achieve aesthetic improvements.
