Primary primitive neuroectodermal tumor (PNET) of the liver is a rare disease with aggressive behavior and poor prognosis. We report a case of a PNET of the liver in a 13-year-old boy. The patient was admitted to the hospital with fever and abdominal pain. Abdominal CT and MRI revealed a 5.5 cm sized, septated, non-enhancing mass in the hepatic hilum. The patient was initially diagnosed with an inflammatory pseudotumor. Despite 9 days of antibiotic therapy, the patient's clinical symptoms did not improve. A liver biopsy was performed in the interest of formulating a differential diagnosis. This procedure revealed tumor cells positive for CD99 on immunohistochemistry. The patient was diagnosed with a PNET.

Group B Streptococcal sepsis and/or meningitis is one of the most serious and common diseases in the neonatal period with high mortality and frequent complications. We have experienced a case of late onset type group B streptococcal sepsis and meningitis with a complication of subclavian vein catheterization catheterization. This 29-day-old male neonate was admitted to intensive care unit with the presentation of fever and septic shock. He was born with Cesarean delivery at 36 weeks and 3 days of gestational age. He showed multiple episodes of seizure after admission and group B streptococcus was isolated from blood. CSF profiles 10 days after admission showed the features of bacterial meningitis without organism isolated. Diffuse cerebral infarction was detected on brain CT 24 days after admission. In the 13th hospital day, the complication of subclavian vein catheterization occurred; Guide wire was cut during insertion and the distal portion of it(2.5cm) was retained in the left subclavian vein. We removed the retained guide wire with goose-neck snare catheter via right femoral vein. This case was presented with a brief review of the literatures.

Spontaneous pneumomediastinum in the absence of predisposing risk factors has been rarely observed in full-term neonates. A 3-day-old neonate, delivered vaginally at term without any perinatal complications or signs of respiratory difficulty, was referred to the Seoul National University Children's Hospital because of reduced heart sound detected during routine neonatal examination. Chest computed tomography (CT) showed air collection in the anterior mediastinum. The baby developed respiratory distress on the fourth day and required supplemental oxygen. On the seventh day, there was no sign of respiratory difficulty, and x-ray examination showed no demonstrable pneumomediastinum. Hence, careful neonatal physical examination is essential during the postnatal assessment of newborns, and spontaneous pneumomediastinum should be considered when a healthy newborn presents with reduced heart sound.

Scoliosis describes a lateral curvature of the spine and is often associated with cosmetic and functional impairments due to severe deformity of the spine. The incidence of adolescent scoliosis is 2-4% of children between 10 and 16 years of age. Eighty five percent of them are idiopathic, in which the most common type of scoliosis is right side-bending. In addition, it is classified into congenital, and secondary scoliosis such as neuromuscular disease and neurofibromatosis. Congenital scoliosis is associated with abnormalities of urinary system(20%), congenital heart diseases(15%), and other abnormalities(10%) such as syringomyelia. We experienced a case of scoliosis by a foreign body(a pencil) in the colon which has never been reported up to date. A brief review of the literature was made.

Congenital diaphragmatic hernias (CDH) usually cause respiratory distress soon after birth and are associated with a high mortality rate in the early postnatal period. However, there is a milder form of CDH that does not manifest during the neonatal period. The late presenting CDH is characterized by a variable clinical picture. We present the case of an otherwise healthy 5-month-old girl, who was referred for evaluation of an 1-day history of vomiting and irritability. Chest simple X-ray and CT showed bowel loops in the left thoracic cavity, which was consistent with diaphragmatic hernia. At operation, she was found to have a small left posterolateral diaphagmatic defect with viable small bowel loops in the left thoracic cavity. After surgical reposition of the hernia, the symptoms such as vomiting and irritability subsided. The lack of typical manifestation of CDH such as respiratory distress may lead to delayed diagnosis. The possibility of late presenting CDH should not be overlooked even after the neonatal period.

Intussusception is a frequent cause of bowel obstruction in the first five years of life and it is one of the most common surgical emergencies in infancy and early childhood. The age of five months child was administered in Department of Pediatrics of Chunchon Sacred Heart Hospital. His main symptoms were vomiting and high fever for three days. Abdominal sonography, air reduction and abdominal computerized tomography (CT) were performed and the conclusion of these study was intussusception due to cyst mass lesion; duplication cyst, mesenteric cyst or Meckel's diverticulum. He was transferred for operation. We had performed laparotomy for reduction of the intussusception. Operative findings revealed ileocolic type of intussusception due to cystic tumor on ileocecal valve that was invaginated into the cecum, and hyperplasia of the Peyer's patch were seen. But we failed manual reduction because of the tumor in the ileocecal area. So we had performed partial resection of the ileocecum. Diverticulum of the ileum was confirmed by pathologic examination. We experienced unusual cause of the intussusception. So we report this case with a review of the literatures.

Nasal obstruction is a cause of respiratory distress in newborns. The congenital nasal airway obstructive abnormalities are classified into three forms according to the location: posterior choanal atresia, nasal cavity stenosis and congenital nasal pyriform aperture stenosis(CNPAS). CNPAS is located at the anterior part of the nasal fossa. CT is the study of choice to make the diagnosis of CNPAS and rule out other causes of nasal obstruction. Though conservative management of CNPAS is recommended, in cases of severe CNPAS surgical treatment should be considered. Calcification of cartilage in the larynx, trachea and bronchi is extremely rare in children. Such calcifications are generally discovered in young children with congenital stridor. The clinical course is favorable. No case with CNPAS and tracheal calcification is reported in newborn. We report a one-day-old girl with CNPAS and tracheal calcification who presented with respiratory difficulty immediately after birth.

Streptococcus milleri Goup Bacteria(SMG) comprise three species, Streptococcus anginosus, Streptococcus intermedius, Streptococcus constellatus. Although they are commensal organism, they can be pathogenic. SMG can be aggressive pathogen in the head and neck with a propensity for abscess formation and local extension of the infection. SMG is culturally and biochemically variable, which makes it hard for the clinicians to recognize it. Hence, it seems that this organism has been relatively neglected. Most of the Lancefield F streptococci are SMG. We report one patient who had Group F streptococcal bacteremia and subdural abscess. According to his medical history, he was diagnosed as membranoproliperative glomerulonephritis three years ago. He complained headache although he was treated by appropiate antibiotics. Brain CT was used as a tool to identify the brain abscess. He had surgical drainage and was treated with IV antibiotics postoperatively.

Objectives: Objective: The purpose of this study is to investigate the treatment of herbal medicine for patients with COVID-19 asymptomatic infections. Method: In English, search engines such as 'PubMed', 'Science Direct', and 'Cumulative Index to Nursing and Allied Health Literature (CINAHL)' were used. In Chinese, search engines such as 'China National Knowledge Infrastructure (CNKI)' and Wanfang were used. The keywords for the search engines were 'COVID-19', 'asymptomatic infection', 'Korean Medicine', 'traditional Chinese medicine', 'herbal medicine', and etc. Only clinical studies using herbal medicine for patients without fever or respiratory symptoms were selected. We excluded the cases that do not fit the research topic. Results: A total of 5 studies were finally selected. Among them, four of them used integrated herbal medicine and Western medicine, and one of the studies treated exclusively for herbal medicine. There were a total of seven prescriptions for herbal medicine used in the study. Outcome variables were used as following: lab test, nucleic acid conversion time, hospitalization period, chest CT, and etc. In the RCT study, herbal medicine and Western medicine decreased nucleic acid conversion time, average hospitalization time compared to the control group, but it was not statistically significant. No other adverse reactions were reported in all studies. Conclusion: According to the results, integrated herbal medicine and Western medicine might be an effective treatment for patients with COVID-19 asymptomatic infection reducing hospitalization period, time of nucleic acid turning negative. No severe adverse effects were reported. However, it is thought that better-designed research will be needed in the future.
