BACKGROUND: Shivering is a common postanesthetic complication. Because all shivering patients feel uncomfortable and increase oxygen consumption, various attempts have been made to prevent its occurrence or to control it. Among the pharmacological methods of treating shivering, meperidine has been known to be the most effective. This study was designed to evaluate whether there was any difference among meperidine, fentanyl, doxapram and normal saline in the treatment of post-anesthetic shivering. METHODS: Forty patients (ASA class I or II) who showed postoperative shivering were randomly assigned into four groups (n=10): Normal saline group: normal saline 5 ml, Doxapram group: doxapram 1.5 mg/kg, Meperidine group: meperidine 25 mg, Fentanyl group: fentanyl 25 microgram. And all patients received routine care: oxygen by T-piece and heat-reflective blanketrol (cincinati Subzero, U.S.A.). Evaluation of the state of shivering was done every 5 minutes from the beginning of the treatment by the same investigator who had injected the drugs intravenously for treatment of shivering. The age, sex, weight and duration of surgery were recorded. RESULTS: There were no significant statistical differences in age, sex, weight and duration of surgery among the four groups. By 5 minutes, 90% of doxapram group and 30% of meperidine group had stopped shivering. By 10 minutes, 90% of doxapram group and 70% of meperidine group had stopped shivering. But in fentanyl and normal saline group, only 20% had stoppd shivering by 10 minutes. CONCLUSIONS: We conclude that both meperidine and doxapram are effective on post-anesthetic shivering. In cases of patient with respiratory depression, doxapram is especially effective because it stimulates the respiratory center.

An 11-year-old girl was diagnosed with encephalitis due to Epstein-Barr virus(EBV). She was admitted to our hospital due to convulsion and decreased consciousness after several days of fever, sore throat and headache. Cerebrospinal fluid analysis showed lymphocyte-dominant pleocytosis and markedly elevated levels of protein. Magnetic resonance imaging(MRI) finding was normal, except for marked leptomeningeal enhancement. Even though she had signs and symptoms of infectious mononucleosis, EBV infection could not be considered as the underlying cause of the encephalitis until IgM for the viral capsid antigen of EBV had been detected in her blood. After treatment with acyclovir, a high dose of methylprednisolone and intravenous immunoglobulin, the neurological symptoms improved rapidly. She has not suffered from any neurological complications in the four months since being discharged. EBV infection should be considered as the main etiology in cases of childhood encephalitis, although there is no evidence of infectious mononucleosis existed.

Orthostasis means standing upright. Thus, orthostatic intolerance (OI) can be simply defined as “the development of symptoms during upright standing, that are relieved by recumbency.” However, OI might be a confusing topic in clinical practice because of the recent appreciation of the condition's clinical variant, emerging understanding of its diverse mechanisms, and its nomenclature, which seems to change annually. OI is not fatal but should be differentiated from potentially lethal disorders, including seizures or cardiogenic syncope. Typical signs and symptoms include loss of consciousness, lightheadedness, and visual difficulties. However, patients also experience multiple and nonspecific symptoms that seem unrelated to orthostatic intolerance, such as headache, fatigue, nausea, abdominal pain, and exercise intolerance. This review was aimed at expanding the comprehension of this confusing and easily missed topic by providing better understanding of the normal hemodynamic response to orthostasis and the basic pathophysiological concepts of major syndromes of OI.

PURPOSE: Human parechovirus (HPeV) and enterovirus (EV) are causative agents of a sepsis-like illness in neonates and of infections of the central nervous system in young children. The objectives of this study were to assess the prevalence of HPeV3 and EV infection in young children with a sepsis-like illness or with meningitis in Jinju, Korea. METHODS: Cerebrospinal fluid (CSF) samples were collected from 267 patients (age range, 1 day to 5 years) and assessed for HPeV and EV by performing reverse transcription polymerase chain reaction assay. Amplification products of the VP3/VP1 region of HPeV and of the VP1 region of EV were sequenced to identify the virus type. RESULTS: HPeV and EV were detected in 3.4% and 7.5% of the total CSF samples assessed, respectively. The age distribution of EV-positive patients (median age, 1.4 months) had a significantly broader range than that of HPeV-positive patients (median age, 7.8 months). The peak seasons for HPeV and EV infection were spring and summer, respectively. The clinical symptoms for HPeV and EV infection were similar, and fever was the most common symptom. Pleocytosis was detected in 22.2% of HPeV-positive patients and 35.5% of EV-positive patients. The VP3/VP1 gene sequence of the nine Korean strains clustered most closely with the Japanese strain (AB759202). CONCLUSION: The data indicate that HPeV infection is predominant in young infants (<6 months) and that meningitis without pleocytosis was caused by both HPeV and EV infection in children.

That rotavirus infection can cause neurological symptoms in young children has been well established. However, it is surprising why rotavirus infection has been overlooked as a cause of neonatal seizures for many years, despite significant research interest in neonatal rotavirus infection. Neonates are the age group most vulnerable to seizures, which are typically attributed to a wide range of causes. By contrast, because rotavirus infection is usually asymptomatic, it has been difficult to identify an association between this virus and neonatal seizures. The conventional wisdom has been that, although neonates are commonly infected with rotavirus, neurological complications are rare in this age. However, recent studies using diffusion-weighted imaging (DWI) have suggested a connection between rotavirus infection and neonatal seizures and that rotavirus infection can induce diffuse white matter injury without direct invasion of the central nervous system. The clinical features of white matter injury in rotavirus-infected neonates include the onset of seizures at days 4–6 of life in apparently healthy term infants. The recent findings seem to contradict the conventional wisdom. However, white matter injury might not be a completely new aspect of rotavirus infection in neonates, considering the forgotten clinical entity of neonatal seizures, 'fifth day fits'. With increased use of DWI in neonatal seizures, we are just starting to understand connection between viral infection and white matter injury in neonates. In this review, we discuss the historical aspects of rotavirus infection and neonatal seizures. We also present the clinical features of white matter injury in neonatal rotavirus infection.

Kawasaki disease (KD) is a systemic vasculitis in infants and young children. However, its natural history has not been fully elucidated because the first case was reported in the late 1960s and patients who have recovered are just now entering middle age. Nevertheless, much evidence has raised concerns regarding the subclinical vascular changes that occur in post-KD patients. KD research has focused on coronary artery aneurysms because they are directly associated with fatality. However, aneurysms have been reported in other extracardiac muscular arteries and their fate seems to resemble that of coronary artery aneurysms. Arterial strokes in KD cases are rarely reported. Asymptomatic ischemic lesions were observed in a prospective study of brain vascular lesions in KD patients with coronary artery aneurysms. The findings of a study of single-photon emission computed tomography suggested that asymptomatic cerebral vasculitis is more common than we believed. Some authors assumed that the need to consider the possibility of brain vascular lesions in severe cases of KD regardless of presence or absence of neurological symptoms. These findings suggest that KD is related with cerebrovascular lesions in children and young adults. Considering the fatal consequences of cerebral vascular involvement in KD patients, increased attention is required. Here we review our understanding of brain vascular involvement in KD.

Cytomegalovirus is a common virus that is mostly asymptomatic when infected, but rarely causes life-threatening hemolysis especially in immunocompromised children. We report a case of antiglobulin test negative severe hemolytic anemia caused by cytomegalovirus infection developed in an immune competent 9-year-old girl. The patient's hemoglobin level was 4.8 g/dL on the day of admission. The diagnosis was achieved by exclusion of other causes of hemolytic anemia and serological evidence of recent CMV infection. The patient was successfully treated with anti-viral agents and steroids resulting in recovery from anemia. Clinicians should consider cytomegalovirus infection in the differential diagnosis of hemolytic anemia in pediatric patients.

There is a wide variety of genital abnormalities observed in patients with Denys-Drash syndrome (DDS). WT1 is thought to influence the genes related to genital development and mutations in this gene have been associated with DDS. DDS should be considered in the differential diagnosis of newborns with genital anomalies. In contrast to other conditions with 46,XY disorders of sex development, individuals with DDS often have duplicated genital organs (a double vagina, cervix or uterus). A double uterus has not yet been reported with 1390G>A (Arg464 Asn) mutation. However, duplicated genitals have been reported with other genetic mutations in patients with DDS. The duplicated genitals in DDS may be associated with low anti-Mullerian hormone (AMH) secretion. Measurement of the AMH levels may add to our understanding of variations in genital development and their abnormalities in disorders such as DDS. In conclusion, this is first case of low level of AMH and double uterus in 1390G>A (Arg464 Asn) mutations of DDS male.

Down syndrome is a rare cause of neonatal cholestasis. Neonatal cholestasis in a patient with Down syndrome is usually associated with severe liver diseases, such as neonatal hemochromatosis, myeloproliferative disorder and intrahepatic bile duct paucity. We experienced a case of idiopathic neonatal cholestasis in a patient with Down syndrome, which resolved spontaneously.

BACKGROUND: A previous history of transfusion has been known to be associated with production of anti-HLA class I antibodies. However, platelet glycoproteins are the main target of idiopathic thrombocytopenic purpura (ITP). The mechanism of antibody production is known to differ significantly between glycoproteins and anti-HLA class I. The aim of this study was to evaluate the clinical significance of anti-HLA class I antibodies in childhood ITP. METHODS: Enrollment for the normal control group targeted 48 people who visited Gyeongsang National University Hospital from 1990 to 2010, and 48 young children with ITP. Anti-glycoproteins and anti-HLA class I antibodies were tested using the Modified Antigen Capture Enzyme-linked immunosorbent assay (MACE) kit. RESULTS: The positive rate of anti-HLA antibodies was significantly different [36/39 (92.3%) vs 29/46 (63%)] [ITP group vs normal control group] (P=0.002). The mean positive S/C ratio of anti-HLA antibodies was also significantly different (3.55 vs 1.51) [ITP group vs normal control group] (P=0.0000). The positive rate of anti-HLA did not differ significantly between the transfused group and the non-transfused group [12/12 (100%) vs 24/27 (88%)] [transfused ITP vs non-transfused ITP]. The mean positive S/C ratio of anti-HLA antibodies did not differ significantly between the transfused ITP group and the non-transfused ITP group (4.30 vs 3.25) [transfused ITP vs non-transfused ITP]. Consecutive testing showed that positive rate and positive S/C ratio of anti-HLA antibodies did not change significantly between sampling times in both groups [transfused ITP vs non-transfused ITP] (P=1.00 and P=0.15). CONCLUSION: Anti-HLA class I antibodies may be involved in childhood ITP. Transfusion did not affect the course of childhood ITP.
