여러 가지 질병들이 신생견의 폐사에 관계된다는 것이 알려지고 있으며 앞으로도 계속적으로 이들 질병에 대한 연구로 신생견의 폐사율을 줄일 수 있을 것으로 보인다. 중요한 것은 신생견이 죽으면 수의사는 그냥 넘기지 말고 반드시 그 원인을 규명하기 위한 노력을 기울여 보다 나은 치료법 개발에 맡은 바 의무를 다할 필요가 있다는 것이다.

Purpose : We studied the usefulness of transcutaneous bilirubinometers in follow-up of bilirubin levels during phototherapy in neonatal jaundice patients. Methods : Transcutaneous bilirubin (TcB) was measured twice per day on 90 neonatal jaundice patients without risk factors of jaundice by transcutaneous bilirubinometer JM-103(Minolta/Hill-Rom Air-shields, Japan). TcB was measured simultaneously on the patched-forehead (TcB-PF), patchedchest(TcB-PC), unpatched-forehead (TcB-UF) and unpatched-chest (TcB-UC) of infants with neonatal jaundice. Plasma bilirubin (PB) was measured by American Optical bilirubinometer (American Optical Co, Buffalo, USA) within 30 minutes after transcutaneous bilirubinometer measurement. Each TcB was compared with PB. Results : In the study group, the mean gestational age was $38.6{\pm}1.3wk$, the mean birthweight was $3,207.0{\pm}472.1g$, the mean age at start of phototherapy was $4.9{\pm}0.9days$ and the mean duration of phototherapy was $1.3{\pm}0.6days$. The correlation between TcB and PB level was observed. The correlation between TcB of the patched part (TcB-PF, TcB-PC) and PB was more significant than that of the unpatched part (TcB-UF, TcB-UC) and PB. The most significant correlation was between PB and TcB-PC. Conclusion : TcB was useful in the follow-up of jaundice during phototherapy as well the screening of jaundice in neonatal jaundice patients. TcB of patched-chest area was the most reliable site in transcutaneous bilirubinometer examination in neonatal jaundice patients.

A nationwide survey was conducted to investigate the annual occurrence rate of neonatal sepsis, maternal risk factors in neonatal sepsis, localized infection in neonates, causative organisms in nosocomial infection and the most common causative organism for neonatal sepsis in Korea. Clinical and bacteriological data wele collected from 37 neonatal units to perform retrospective review of the medical records of the newborn infants who were confirmed as having neonatal sepsis and whose blood culture was collected to isolate organisms for one year study period from January to December in 1997. 78,463 neonates were born at 37 hospital in 1997, and 20,869 neonates were admitted to the neonatal units, During this period, 772 episodes of neonatal sepsis were recorded in 517 neonates. The occurrence rate of neonatal sepsis was 0.73%(0~2.95%). Male to female ratio was 1.15:1, and 303 cases(42.1%) were born prematurely. The main pathogens of early onset of sepsis were S. aureus(20%), S. epidermidis(14.4%) and coagulase negative staphylococcus(14. 4%). Gram negative bacilli including Enterobacter spp (7.2%), E. coli(5.1%), Klepstella(4.5%), Pseudomonas(3.7%) and Enterobacter faectum(3.6%) accounted for 24.1% of sepsis. Group B beta-hemolytic streptococcus were isolated only in two cases. Common obstetric factors were PROM(21.1%), difficulty delivery(18.7%), fetal tachycardia(5.3%), chorioamnionitis(4.9%), and maternal fever(4.7%). The main pathogens of late-onset sepsis were S. aureus(22.3%), S. epidermidis(20.4%) and CONS(9.9%). There were 6 cases(1.0%) of Candida sepsis, Frequent focal infections accompanying sepsis were pneumonia(26.1%), urinary tract infection(10.5%), meningitis(8.2%), and arthritis(3.6%), S. epidermidis(22.0%) and s. aureus(21.7%) were also the most common pathogens in 373 nosocomial infection.

Neonatal bleeding is a common problem encountered in nursery rooms or neonatal intensive care units, especially among premature infants. Furthermore, owing to recent remarkable improvement of neonatology, survival rates of preterm neonates have increased; hence, neonatal bleeding cannot be emphasized enough. Since the total blood volume of neonates is small, bleeding can be one of the causes of morbidities and mortalities. Therefore, rapid diagnosis and immediate therapy is urgently needed. The patient's medical history including a familial history of a bleeding disorder or of a previously affected infant who suffered from bleeding along with maternal and neonatal drugs can provide important diagnostic clues. Presence of bleeding with or without petechiae and ecchymoses in a healthy term or late preterm infant with thrombocytopenia but normal prothrombin time and activated partial thromboplastin time strongly suggests a congenital bleeding disorder. For a sick infant who is bleeding from multiple sites, an acquired disorder such as disseminated intravascular coagulation is suspected. Intracranial hemorrhage in term or late preterm infants without a history of birth trauma is highly suggestive of coagulation disorders. The purpose of this review is to summarize recent advances in diagnostic methods is as well as basic concepts of neonatal hemostatic disorders. First, an outline of background information will be presented followed by a discussion of primary and secondary hemostatic disorders as well as inherited and acquired disorders.

Classic galactosemia (OMIM #230400) is an autosomal recessive inherited metaboic disorder caused by a deficiency of the galactose-1-phosphate uridyltransferase (GALT, EC2.7.7.12) due to mutations in the GALT gene. If untreated, classic galactosemia is a potentially lethal disease presenting with poor feeding, vomiting, jaundice, liver failure, increased bleeding tendency, and septicemia leading to death within a few days after birth. Since 2006, expansion of newborn screening has been enabled the early diagnosis and early intervention of classic galactosemia in Korea. However, newborn screening, followup testing for confirmatory diagnosis and intervention for galactosemia continue to present challenges. In Korea, the prevalence of the classic galactosemia is considered relatively low compared to that of western countries. And the genotype is also clearly different from those of other population. Therefore, our own guideline for confirmatory diagnosis and intervention is needed. Here, the diagnostic algorithm for galactosemia after positive newborn screening result in Korea has been proposed. Considering the low prevalence and different mutation spectrum in Koreans, the early mutation analysis of GALT gene could be a useful tool for the accurate diagnosis and making any treatment decision.

Purpose : We investigated the causative organisms of bacterial meningitis by age distribution from 1996 to 2005. Methods : Retrospective data were obtained from the medical records with diagnosis of bacterial meningitis or neonatal meningitis from 1996 through 2005. A case was defined by isolation of organism or detection of its antigen by latex agglutination from cerebrospinal fluid. Results : A total of 46 cases(27 neonates and 19 children) were identified. 15 of 27 episodes(55.6%) of neonatal meningitis had a concomitant-positive blood culture. Group B streptococci were the most common bacterial causes of neonatal meningitis(44.4%). Nine of 12 episodes(75.0%) were late-onset infections in neonatal meningitis caused by group B streptococci. 16 of 19 children(84.2%) with bacterial meningitis beyond the neonatal period were younger than 5 years of age(median age, 23 months). Of 19 cases, 8 infections were with Streptococcus pneumoniae, 8 were with Haemophilus influenzae and 3 were with Neisseria meningitidis. Since 2001 there was no case of meningococcal meningitis in this study. Conclusion : In neonates group B streptococci are the most common causative organisms of bacterial meningitis, especially late-onset infections. In infants and young children, the predominant causes of bacterial meningitis are H. influenzae and S. pneumoniae; meningitis caused by the former are likely to decrease after the introduction of the conjugate vaccine for H. influenzae type b.

Purpose: Congenital tuberculosis (TB) is difficult to diagnose owing to its non-specific symptoms. Delayed diagnosis increases the risk of nosocomial infections. We examined the TB status of infants and healthcare workers who were in proximity to preterm twins diagnosed with congenital TB 63 days after birth and 48 days after admission to the neonatal intensive care unit (NICU). Methods: Contact investigations were conducted on 24 staff members and 35 infants who had contact with the twins with congenital TB. Results: Two of the exposed infants, both of whom had received the Bacille Calmette-Guérin vaccine, had positive tuberculin skin test results. Four of the 24 exposed staff members had positive interferon-gamma release assay (IGRA) test results before exposure and were not re-tested after exposure; the remaining 20 had negative IGRA test results. All exposed staff members and infants had normal chest radiographic findings. Conclusions: Although transmission of TB in the NICU is unusual, it can occur. These results support the need for a systematic investigation of the TB status of exposed infants, their family members, and healthcare workers.

Spontaneous intraperitoneal extravasation of urine is rare. Perirenal urinoma may develop when obstruction to urinary flow creates sufficient back pressure to produce extravasation of urine. Urinary ascites most commonly indicate a disruption to the integrity of the urinary tract. We report a case of urinary ascites with urinoma resulting from an ureteropelvic junction obstruction in a neonate.

There are varying opinions about theories that the middle ear of Neonates is filled with mucous or other Material that interference with normal mobility of the middle ear system. DeDMon reported on the acoustic reflex as a tool for Neonatal screening, and Keith investigated the Middle ear function of Neonates during first few hours of life with an Electroacoustic impedance bridge. There are no reports on Neonstes in Impedance Audiometry in Korea. We tested 100 Neonates less than 24 hours old and this paper is dealt with its study related with tympanogram, static compliance and acoustic reflex.
