Lipoma Arborescens is rarely encountered in hip joint. This term was first used by Mueller in 1838, to describe a fatty trmor of the knee which presented branched villous-like projection. The etiology is unknown, Suggests its probable reationship to tuberculosis, rheumatoid arthitis, trauma, chronic inflammation, diabetes mellitus and degenerative arthritis. It frequently involves knee joint, hand, wrist, foot, ankle, tendon sheath and hip joint. It usually presents bilaterally. Their nonspecific symptoms and signs are mild pain, joint swelling with minimum effusion, festriction of joint motion, redness, local heating and crepitus. We experienced a case of lipoma arborescens of hip joint, which was treated by synovectomy with excision of lesion.

Pericardial effusion (PCE) in neonates has various clinical presentations depending on the amount and speed of fluid accumulation and can cause cardiac tamponade (CT). We report a case of rapidly accumulating PCE and near-fatal CT with an umbilical venous catheter successfully resolved by emergent echo-guided pericardiocentesis in a term infant who had been hospitalized with meconium aspiration syndrome and persistent pulmonary hypertension. This case report suggests that if a patient with an intracardiac umbilical catheter shows sudden cardiopulmonary instability, the possibility of PCE and CT should be considered. Furthermore, if necessary, emergency drainage of the PCE and removal of the umbilical catheter should be immediately performed.

Background:
To evaluate how intrauterine stress affects extremely premature infants in terms of intrauterine growth restriction. We hypothesized that extremely premature infants with mildly-low ponderal index (MPI) would have better neonatal outcomes.
Methods:
We selected 2,721 subjects of 23 to 28 weeks of gestation between 2013 and 2015 from Korean Neonatal Network database. They were divided into 4 groups based on ponderal index (PI) percentile; PI ≤ 3rd as severely-low PI (SPI, n = 82), 3rd < PI ≤ 10th as MPI (n = 190), 10th < PI ≤ 90th as adequate PI (API, n = 2,179), and PI > 90th as high PI (HPI, n = 270).
Results:
The mortality in MPI and API groups was comparable (16.3% vs. 16.9%). It was significantly lower than that in the SPI and HPI groups (30.5% and 24.9%, respectively;P = 0.001). The MPI and API groups had better neonatal morbidities compared with the SPI and/or HPI groups, while the MPI group (8.2%) showed a lower incidence of severe intraventricular hemorrhage (IVH) than the other groups (SPI, 21.3%; API, 15.0%; HPI, 19.7%, respectively; P = 0.004). The MPI group had a trend of a bottom in neonatal mortality and morbidities in extremely premature infants.
Conclusion
The MPI and API groups had lower mortality, massive pulmonary hemorrhage, severe bronchopulmonary dysplasia or death, pulmonary hypertension and neonatal seizure rates than the SPI and/or HPI groups, while the MPI group showed a lower incidence of severe IVH than the other groups. We speculate that the lower incidence of neonatal morbidities and mortality in the MPI group indicating mild intrauterine stress might accelerate fetal maturation resulting in better outcomes in extremely premature infants.

Cerebellar hemorrhage in full-term infants is a rare condition recently recognized in high-risk newborns requiring intensive care with the availability of advanced neuroimaging techniques. Several aspects such as the incidence, pathophysiology, clinical features, and prognosis of cerebellar hemorrhage in full-term infants remain unknown. We present a case of cerebellar hemorrhage with subdural hemorrhage in a patient hospitalized for jaundice after birth without a history of traumatic delivery, such as breech presentation, prolonged labor or forceps delivery. A full-term female infant weighing 3,100 g at birth, with no complications during delivery, developed jaundice within 48 hours of birth and was admitted for intensive phototherapy in the first 3 days of life with a transcutaneous total bilirubin level of 18.1 mg/dL. Magnetic resonance imaging revealed cerebellar brain lesions with a subdural hemorrhage. At the age of 3 months, the infant exhibited leg rigidity and was referred for rehabilitation. The patient showed signs of improvement during treatment and was generally catching up well with her peers at the age of 9 months. Long-term follow-ups are required to evaluate the consequences on cognitive development, behavior, and motor performance subsequently in life.

Congenital hepatic fibrosis is a developmental abnormality that may appear either sporadically or in a familial form. It is an inherited disease defined pathologically by bands of fibrous tissue within the liver, and is occasionally associated with cystic kidney disease. A 21-year-old woman was admitted to our hospital for evaluation of pancytopenia. She showed esophageal varices, hepatomegaly and splenomegaly, but had normal results on her liver function test. Peripheral stigmata of chronic liver disease such as palmar erythema or spider angioma was not found. Hepatosplenomegaly, polycystic kidney and psoas muscle cyst were detected through an abdominal CT and MRI. The patient is diagnosis was confirmed as congenital hepatic fibrosis using laparoscopic liver biopsy. The first case of congenital hepatic fibrosis associated with polycystic kidney disease in Korea is herein reported.

Background:
Lipopolysaccharide (LPS) exerts cytotoxic effects on brain cells, especially on those belonging to the oligodendrocyte lineage, in preterm infants. The susceptibility of oligodendrocyte lineage cells to LPS-induced inflammation is dependent on the developmental stage. This study aimed to investigate the effect of LPS on oligodendrocyte lineage cells at different developmental stages in a microglial cell and oligodendrocyte coculture model.
Methods:
The primary cultures of oligodendrocytes and microglia cells were prepared from the forebrains of 2-day-old Sprague–Dawley rats. The oligodendrocyte progenitor cells (OPCs) co-cultured with microglial cells were treated with 0 (control), 0.01, 0.1, and 1 µg/mL LPS at the D3 stage to determine the dose of LPS that impairs oligodendrocyte differentiation. The co-culture was treated with 0.01 µg/mL LPS, which was the lowest dose that did not impair oligodendrocyte differentiation, at the developmental stages D1 (early LPS group), D3 (late LPS group), or D1 and D3 (double LPS group). On day 7 of differentiation, oligodendrocytes were subjected to neural glial antigen 2 (NG2) and myelin basic protein (MBP) immunostaining to examine the number of OPCs and mature oligodendrocytes, respectively.
Results:
LPS dose-dependently decreased the proportion of mature oligodendrocytes (MBP+ cells) relative to the total number of cells. The number of MBP+ cells in the early LPS group was significantly lower than that in the late LPS group. Compared with those in the control group, the MBP+ cell numbers were significantly lower and the NG2+ cell numbers were significantly higher in the double LPS group, which exhibited impaired oligodendrocyte lineage cell development, on day 7 of differentiation.
Conclusion
Repetitive LPS stimulation during development significantly inhibited brain cell development by impairing oligodendrocyte differentiation. In contrast, brain cell development was not affected in the late LPS group. These findings suggest that inflammation at the early developmental stage of oligodendrocytes increases the susceptibility of the preterm brain to inflammation-induced injury.

OBJECTIVES: The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. METHODS: Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. RESULTS: Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. CONCLUSION: The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

We think that the clinical courses of lacurlar infarctions are somewhat different from those of cortical ones, because the ischemic penumbra, a keystone of acute infarct recovery, of the former is rnore limitted than that of the latter. Therefore, we analyzed the selected data, 38 cortical and 33 lacunar infarct patients, from Severance Stroke Registry which were recorded from May, 1989 to April, 1990, to demonstrate and compare the differences of the clinical courses and its influencing factors between the cortical and lacunar infarcts. Our results suggested as follows first, the initial neurologic deficits of cortical infarctions are rnore serious than those of lacunar infarctions, but with the better short-term improvements of tbe former, the short-term motor outcome between the two types of infarcts are not significantly different second, whiIe the short-term improvernent of cortical infarcs is influenced by initial hematocrit level, the short-term motor outcome and the degree of improvement of lacunar infarcts are influenced by the patient's age.

Social welfare services for respiratory-disabled persons in Korea are offered based on the respiratory impairment grade, which is determined by 3 clinical parameters; dyspnea, forced expiratory volume in 1 second (FEV1), and arterial oxygen tension. This grading system has several limitations in the objective assessment of respiratory impairment. We reviewed several guidelines for the evaluation of respiratory impairment and relevant articles. Then, we discussed a new grading system with respiratory physicians. Both researchers and respiratory physicians agreed that pulmonary function tests are essential in assessing the severity of respiratory impairment, forced vital capacity (FVC), FEV1 and single breath diffusing capacity (DLco) are the primarily recommended tests. In addition, we agreed that arterial blood gas analysis should be reserved for selected patients. In conclusion, we propose a new respiratory impairment grading system utilizing a combination FVC, FEV1 and DLco scores, with more social discussion included.

Chronic obstructive pulmonary disease (COPD) is a substantially under-diagnosed disorder, and the diagnosis is usually delayed until the disease is advanced. However, the benefit of early diagnosis is not yet clear, and there are no guidelines in Korea for doing early diagnosis. This review highlights several issues regarding early diagnosis of COPD. On the basis of several lines of evidence, early diagnosis seems quite necessary and beneficial to patients. Early diagnosis can be approached by several methods, but it should be confirmed by quality-controlled spirometry. Compared with its potential benefit, the adverse effects of spirometry or pharmacotherapy appear relatively small. Although it is difficult to evaluate the benefit of early diagnosis by well-designed trials, several lines of evidence suggest that we should try to diagnose and manage patients with COPD at early stages of the disease.
