Hybrid systems prepared by fixing a Re(i) complex and a dye on three types of TiO2 nanoparticles in two different ways commonly revealed persistent photocatalysis of the CO2 reduction to CO with no levelling-off tendency under visible-light irradiation in DMF, giving a turnover number of ≥435.

PurposeTransient tachypnea of the newborn (TTN) is a disorder caused by the delayed clearance of fetal alveolar fluid. β-adrenergic agonists such as albuterol (salbutamol) are known to catalyze lung fluid absorption. This study examined whether inhalational salbutamol therapy could improve clinical symptoms in TTN. Additional endpoints included the diagnostic and therapeutic efficacy of salbutamol as well as its overall safety.MethodsFrom January 2010 through December 2010, we conducted a prospective study of 40 newborns hospitalized with TTN in the neonatal intensive care unit. Patients were given either inhalational salbutamol (28 patients) or placebo (12 patients), and clinical indices were compared.ResultsThe duration of tachypnea was shorter in patients receiving inhalational salbutamol therapy, although this difference was not statistically significant. The duration of supplemental oxygen therapy and the duration of empiric antibiotic treatment were significantly shorter in the salbutamol-treated group. No adverse effects were observed in either treatment group.ConclusionsInhalational salbutamol therapy reduced the duration of supplemental oxygen therapy and the duration of empiric antibiotic treatment, with no adverse effects. However, the time between salbutamol therapy and clinical improvement was too long to allow definitive conclusions to be drawn. Further studies examining a larger number of patients with strict control over dosage and frequency of salbutamol inhalations are necessary to better direct the treatment of TTN.

Background: Furosemide is known to increase renal prostaglandin synthesis. However, its influence on ductal closure and renal toxicities of indomethacin in preterm infants has not been conclusive, especially during the early neonatal period. Objectives: To identify the effects of furosemide after indomethacin administration on the rate of patent ductus arteriosus (PDA) closure and renal function in preterm infants. Methods: 68 infants (gestational age <34 weeks and birth weight <2,000 g) receiving indomethacin therapy (one course: 0.2–0.1–0.1 mg/kg q 12 h, mostly started <48 h after birth) were randomly assigned to the furosemide (n = 35) or control (n = 33) group. Each indomethacin dose was followed by furosemide (1.0 mg/kg) or placebo. The primary (PDA closure) and secondary (acute renal failure (ARF) and others) outcomes were assessed. Renal parameters before and 0–12 and 24–36 h after the first course of indomethacin were also investigated. Results: In an intention-to-treat analysis, there were no differences in the PDA closure rate between the furosemide (29/34) and the control (27/29) group (p = 0.437). The incidence of ARF (serum creatinine >1.6 mg/dl) was greater in the furosemide group (20/34) than in the control group (3/29) (p < 0.001). Compared with the control group, serum creatinine and cystatin C levels and fractional excretion of sodium were significantly increased in the furosemide group for 24–36 h after indomethacin therapy (p < 0.01). There were no between-group differences in mortality and other neonatal morbidity rates. Conclusions: Use of furosemide in combination with indomethacin increased the incidence of ARF but did not affect the PDA closure rate in preterm infants.

Congenital infantile fibrosarcoma (CIF) is a rare soft-tissue tumor in the pediatric age group and seldom involves the gastrointestinal tract. A 2-day-old boy was transferred to our hospital with a pneumpoperitoneum. After emergency operation, we could find a solid mass wrapping around a sigmoid colon and performed a segmental resection of sigmoid colon including a mass. Histopathologic examination showed an infantile fibrosarcoma origining from the muscular layer of colon. The baby was discharged on the 17th hospital day and followed for 1 yr without recurrence.

This study showed the epidemiology and risk factors of RSV hospitalization in preterm infants in Korea. RSV infection was one of the main causes of hospitalization after discharge from the neonatal intensive care unit in patients born at <35 weeks of gestational age.

From a surgical perspective, complex jejunal atresia can cause many critical problems after the correction operation. An aggressive and multidisciplinary approach is necessary for managing this condition.

PurposeGastroesophageal reflux in infant is a physiological process. However, surgery is performed in high risk infants with severe gastroesophageal reflux disease (GERD) when medical management fails. This study focuses on efficacy and safety of Nissen fundoplication for GERD in infants under age 12 months.MethodsThis study was a retrospective case analysis of 11 neonates and infants under 12 months of age who underwent Nissen fundoplication following a failure of medical treatment between June 2010 and June 2013 at Pusan National University Children's Hospital. The records were reviewed to determine the effect of fundoplication on symptoms and post-operative complications.ResultsA total of 11 infants consist of four males and seven females. Mean birth weight was 2,305.5±558.6 g (1,390-3,130 g). They had some underlying disease, which are not related with GERD such as congenital heart disease (54.5%), prematurity (45.5%), neurologic disease (18.2%), respiratory disease (18.2%), and other gastrointestinal disease. Mean body weight at surgery was 3,803.6±1,864.9 g (1,938.7-5,668.5 g). Mean age at operation was 99.9±107.6 days (17-276 days). Duration from operation to full enteral feeding was 10.9 days. Symptoms related GERD disappeared in all patients including one who got reoperation. One infant died of congenital heart disease unrelated to surgery. There were no complications related to fundoplication.ConclusionFundoplication is effective and safe treatment in the neonates and infants with severe GERD.

Iliopsoas abscess (IPA) is rare in neonates. We present a case of neonatal IPA that was initially believed to bean inguinal hernia. A 20-day-old male infant was referred to our hospital for herniorrhaphy after a 2-day history of swelling and bluish discoloration of the left inguinal area and leg without limitation of motion. Abdominal and pelvic ultrasonography suggested a femoral hernia, but the anatomy was unclear. Abdominal computed tomography revealed a multi-septated cystic mass extending into the psoas muscle from the lower pole of the left kidney to the femur neck. Broad spectrum antibiotics were initiated, and prompt surgical exploration was planned. After opening the retroperitoneal cavity via an inguinal incision, an IPA was diagnosed and surgically drained. Culture of the abscess fluid detected Staphylococcus aureus, sensitive to methicillin. The patient was discharged without complication on the 17th postoperative day.Graphical Abstract
