Tracheoinnominate artery fistula is a rare, fatal complication of tracheostomy, and prompt diagnosis and management are imperative. We report the case of tracheoinnominate artery fistula after tracheostomy in a 14-year-old boy with a history of severe periventricular leukomalacia, hydrocephalus, cerebral palsy, and epilepsy. The tracheoinnominate artery fistula was successfully treated with a stent graft insertion via the right common femoral artery. Endovascular repair of the tracheoinnominate artery fistula via stent grafting is a safe, effective, and minimally invasive treatment for patients in poor clinical conditions and is an alternative to traditional open surgical treatment.
Background: nosocomial sepsis remains a significant source of morbidity and mortality in extremely low birth weight (ELBW) infants. Early and accurate diagnosis is very important, but it is difficult due to the similarities in clinical manifestation between the causative microorganisms. We tried to identify the differences between causative microorganisms in clinical and laboratory findings and to help choose antibiotics, when sepsis was suspected in ELBW infants. Methods: a retrospective study was conducted on preterm infants, born at less than 28 weeks of gestation, with a birth weight of less than 1000 g between January 2009 and December 2019. Clinical and laboratory findings of suspected sepsis, after the first 72 h of life, were assessed. We classified them into four groups according to blood culture results (gram positive, gram negative, fungal, and negative culture groups) and compared them. Results: a total of 158 patients were included after using the exclusion criteria, with 45 (29%) in the gram positive group, 35 (22%) in the gram negative group, 27 (17%) in the fungal group, and 51 (32%) in the negative culture group. There were no significant differences in mean gestational age, birth weight, and neonatal morbidities, except for the age of onset, which was earlier in the fungal group than other groups. White blood cell (WBC) counts were the highest in the gram negative group and the lowest in the fungal group. The mean platelet counts were the lowest in the fungal group. C-reactive protein (CRP) levels were the highest in the gram negative group, while glucose was the highest in the fungal group. Conclusions: in conclusion, we showed that there are some differences in laboratory findings, according to causative microorganisms in the nosocomial sepsis of ELBW infants. Increased WBC and CRP were associated with gram negative infection, while decreased platelet and glucose level were associated with fungal infection. These data may be helpful for choosing empirical antibiotics when sepsis is suspected.
Objective: Volume and pressure loading of the ventricles are associated with increased plasma Btype natriuretic peptide (BNP) levels. Hemodynamically significant patent ductus arteriosus (hsPDA) is a risk factor for life-threatening conditions in preterm infants. We compared follow-up data such as echocardiograms, BNP levels, comorbidities, and prognosis in preterm infants with PDA, and investigated the relationship between maternal prenatal factors and BNP. Methods: This single-center study performed between January 2015 and August 2016 included 63 preterm infants with a gestational age of <35 weeks. We retrospectively evaluated the BNP levels on postnatal day 1, 3, and 7, clinical features, treatment method for PDA, mortality, and maternal prenatal factors. Results: Lower gestational age and smaller birth weight were associated with a higher incidence of hsPDA (P<0.01). Postnatal day 3 BNP levels were significantly higher in the hsPDA group. BNP levels were not associated with failure of medication in the hsPDA group. Postnatal day 1 BNP levels were associated with an abnormal umbilical artery flow (P=0.017), and deceleration in fetal non-stress test result (P=0.01) but not with other maternal states. Conclusion: BNP levels are a useful predictive biomarker for hsPDA in preterm infants during the 3rd days of life; however, they do not help in decision-making regarding treatment. BNP levels on the 1st postnatal day showed a positive correlation with prenatal factors such as abnormal umbilical artery flow and deceleration in fetal NST result.
Purpose: Syphilis infections are becoming more prevalent in the Republic of Korea, and inadequately treated syphilis can lead to congenital syphilis (CS) in newborns. This study aimed to analyze the clinical manifestations of syphilis in mothers and newborns and to make suggestions to improve disease prognosis. Methods: This single-center study was performed between August 2009 and August 2019 and included 29 newborns with CS. We retrospectively evaluated the clinical features, rapid plasma reagin (RPR) card test, fluorescent treponemal antibody absorption test (FTA-ABS), morbidity, and treatment regimen of all the syphilis-affected mothers and their newborns. Results: At the time of delivery, mean maternal age was 29.0±6.1 years old, and newborn gestational age was 38.0 weeks. In cases when syphilis was confirmed during the second and third trimesters of pregnancy, the newborn with CS had morbidity (p=0.004). The mean RPR titer was related to morbidity (p= 0.036). Positive results of FTA-ABS IgM (p<0.001) and pleocytosis in the cerebrospinal fluid (CSF) (p= 0.020) also increase morbidity. The most common symptoms were desquamation and skin rash, followed by hepatomegaly, neurodevelopmental disability, and bone abnormalities. The highest number of CS cases per 1,000 live births in this hospital was in 2014. Conclusion: CS is a preventable and treatable disease if physicians detect symptoms and provide appropriate treatment through RPR examinations during every trimester. General practitioners should be widely trained on various aspects including early detection, formal treatment, and regular follow-up. Additionally, medical services should be provided for the entire childbearing population regardless of the socioeconomic status.
Purpose: Meconium aspiration syndrome is an important cause of neonatal morbidity and mortality, and sometimes patients need mechanical ventilator therapy. The aim of this study was to identify the risk factors which required mechanical ventilation. Methods: We retrospectively analyzed 44 infants diagnosed as meconium aspiration syndrome from January 2009 to December 2013. We divided into 2 groups (ventilator group and oxygen therapy group) and analyzed the clinical characteristics, vital signs, laboratory findings and clinical courses. Results: Ventilator group and oxygen therapy group included each 22 infants, and there were no significant differences in clinical characteristics between two groups. Time to transfer and time to start oxygen therapy were longer in ventilator group but not statistical difference. Initial mean blood pressure and pH were significantly lower in ventilator group than in oxygen therapy group (P=0.026, P=0.003). Ventilator group had longer treatment period and worse prognosis than oxygen therapy group. Conclusion: If the infants with meconium aspiration and respiratory distress represent low pH and hypotension, we have to pay close attention to early oxygen supplementation and proper treatment to prevent poor clinical course.
to December 2012. We retrospectively reviewed the medical records of the patients. Results: The median age of the patients was 16 years old; 11 patients were aged 10 to 14 and 43 patients were aged 15 to 18. Among 54 patients, 19 had history of contact with pulmonary TB, 10 had contact with house members (household), and remaining 9 had contact with classmates (non-household). One out of 10 patients who had household contacts and 6 out of 9 patients who had non-household contacts were evaluated with contact investigation after the exposure to pulmonary TB. Among 7 patients who were evaluated with contact investigation, 3 were diagnosed with active pulmonary TB, 1 had latent tuberculosis infection (LTBI), and 3 had no evidence of TB or LTBI. The median period of diagnosis after the exposure to active pulmonary TB was 2 years in patients with household contacts and 0.23 years in patients with nonhousehold contacts. Conclusion: This study suggested that if the contact investigation conducted properly, it would be helpful for early diagnosis and prevention of pulmonary TB.
Purpose: Since premature infants are sensitive to the changes in blood glucose levels and body temperature, maintaining these parameters is important to avoid the risk of infections. The authors implemented the Golden Hour protocol (GHP) that aims to close the final incubator within one hour of birth by implementing early treatment steps for premature infants after birth, such as maintaining body temperature, securing airway, and rapidly administering glucose fluid and prophylactic antibiotics by securing breathing and rapid blood vessels. This study investigated the effect of GHP application on the short- and long-term clinical outcomes.Methods: We retrospectively analyzed the medical records between 2017 and 2018 before GHP application and between 2019 and 2020 after GHP application in preterm infants aged 24 weeks or older and those aged less than 33 weeks who were admitted to the neonatal intensive care unit.Results: Overall, 117 GHP patients and 81 patients without GHP were compared and analyzed. Peripheral vascularization time and prophylactic antibiotic administration time were shortened in the GHP-treated group (P=0.007 and P=0.008). In the short-term results, the GHP-treated group showed reduced hypothermia upon arrival at the neonatal intensive care unit (P=0.002), and the blood glucose level at 1 hour of hospitalization was higher (P=0.012). Furthermore, the incidence of neonatal necrotizing enteritis decreased (P=0.043). As a long-term result, the incidence of BPD was reduced (P=0.004).Conclusion: We confirmed that applying GHP improved short- and long-term clinical outcomes in premature infants aged <33 weeks age of gestation, and we expect to improve the treatment quality by actively using it for postnatal treatment.
