Pediatric Acute Confusional Migraine / 계명의대학술지

Acute confusional migraine (ACM) is a rare type of migraine variant. It is primary seen in adolescent with migraine history. The specific symptom is an acute confusional mental change after acute onset headache. Symptoms include decreased alertness, disorientation, speech disturbance, agitation, difficulty in recognizing family and familiar locations, and amnesia. Patients mainly visit to emergency department due to acute mental problems. But there are no specific findings in neuroradiologic examinations and laboratory tests in ACM patients. And ACM is not widely known disease to physicians. So it takes long time to exclude other disorders and dysfunctions until to reach the diagnosis. Patient’s history of migraine, family history, and spontaneous relief of symptoms after deep sleep without medication can be helpful in diagnosis. We experienced a rare case of ACM of 13-year-old male patient, therefore we report the case with literature review.

A Study on Factors Associated with Duration of Influenza Virus Shedding in Children / 계명의대학술지

To prevent the spread of influenza among infants and adolescents attending kindergartens and schools, proper quarantining of those who are ill is necessary. In this study, the rapid antigen test (RAT) was performed in patients to investigate the factors affecting the duration of virus shedding. The study included pediatric patients who were diagnosed with influenza by RAT at Daedong Hospital between November 2016 and April 2019. We identified the influenza subtype, age, gender, fever duration, oseltamivir medications, and time gap between fever subsided and RAT examination through chart review. A total of 330 patients were examined at discharge. The average age for RAT positive and negative patients was 6.32 ± 4.26 years and 8.47 ± 4.54 years, respectively. The average duration of fever for the RAT positive patients was 3.84 ± 1.09 days, and for those who were RAT negative was 4.191 ± 1.39. The average number of doses oseltamivir for RAT positive and negative patients was 7.68 ± 1.57 and 8.72 ± 1.37, respectively. The RAT was performed 24 to 48 hours after fever subsided (TG 24–48H group). At this time, 60 patients were positive and the rate of positive expression was 55.56%. Of the TG 48–72H group, 36 patients (26.09%) were positive. Of the TG 72–96H group, 18 patients (21.43%) were positive. Age, fever duration, number of doses oseltamivir and time gap after fever subsided were the factors that influenced the duration of influenza virus shedding. These factors should be considered during the quarantining influenza patients.

A Survey of Doctors' Awareness of Simultaneous Vaccination

PURPOSE: In this study, doctors were surveyed with a questionnaire to determine whether they performed simultaneous vaccination and whether there were any concerns about safety or anxiety. The purpose of this study was to determine any problems associated with doctors readily performing simultaneous vaccination. METHODS: A trained surveyor visited 241 doctors from every institution registered with the National Immunization Program (NIP) located within six districts (gu) in the City of Busan (Dongnae-gu, Geumjeong-gu, Yeonje-gu, Suyeong-gu, Busanjin-gu, Haeundae-gu); a total of 155 (64%) valid responses were obtained. RESULTS: Of the 155 respondents, 144 (93%) were already performing simultaneous immunizations and 141 (91%) had a positive view of the practice. However, among the 144 doctors performing simultaneous immunizations, 67 (47%) were not confident about its safety; side effects were seen after simultaneous immunization by 86 doctors, 35 (41%) of whom believed that the frequency or possibility of side effects in simultaneous immunizations was higher than that in sequential immunizations. CONCLUSIONS: The use of simultaneous immunization is expanding quickly. However, among the doctors performing simultaneous immunizations, a high percentage had concerns over its unproven safety and potential side effects, indicating the need for academic societies or government institutions to present evidence to address such concerns.

High Proportion of Nervous System Disease among Major Cause of Under-Five Death in Korea; Compared with OECD 14 Nations (2005-2010) / 고신대학교의과대학학술지

OBJECTIVES: To compare the mortality rate of children under ages five from different countries by their causes and to explore the cause of death that is relatively higher in South Korea and came up with measures for resolution. METHODS: The statistics were based from section ICD(International Classification of Diseases)-10 of WHO(World Health Organization) Mortality Database. Among the OECD(Organization for Economic Cooperation and Development) countries, 15 countries with higher GDP(Gross Domestic Product) than South Korea were studied by the mortality rate from 2005 to 2010 sorted into two groups: 0 year group and 1-4 years group. Then the cause of death investigated in detail. RESULTS: Among the 15 countries, average mortality of 0 year group in Korea ranked 8th and the average mortality of 1-4 years group ranked 4th out of 15. There were no significance in the mortality of 0 year group caused by any specific disease, but unnatural death was ranked 2nd after the United States. The natural death of 1-4 years group was ranked 6th, and the unnatural death was ranked 2nd after the Unites States. Among the natural deaths of 1-4 years group, the cause of death significantly higher was found to be disease G(nervous system disease). Among the subgroups of disease G, the orders went epilepsy, cerebral palsy, paralysis, and inflammatory disease. CONCLUSIONS: We have identified major causes of death of children under age 5. The highest proportion of cause of death in 1-4 years group was nervous system disease and we have proposed resolution. Henceforth, this data will be used as a foundational data for formulating policies relation to the Mother-Child Health.

The Study in Vitamin D Concentration in the Blood for Infants with High Level of Alkaline Phosphatase / 고신대학교의과대학학술지

OBJECTIVES: Nowadays most infants on exclusively breast feeding have vitamin D deficiency due to the increase of breast feeding. However, domestic research lacks appropriate materials. Therefore, we researched practical clinical aspects of vitamin D deficiency related to breast milk feeding for infants who have a high amount of alkaline phosphatase (> 500 IU/L). METHODS: The subjects of the study were 31 infants with high alkaline phosphatase level. We tested with 25-hydroxycholecalciferol (25-OHD3), parathyroid hormone, calcium, ionized calcium, phosphorus in their blood and with a wrist x-ray. Then, we divided them into two groups of breast feeding and formula feeding and compared the results. RESULTS: Eighteen infants (58%) out of 31 infants that have high alkaline phosphatase were vitamin D insufficiency or deficiency, and 16 (100%) breast feeding infants of them showed vitamin D deficiency or insufficiency. However, only 2 (13%) of 15 formula feeding infants were at insufficiency. There was a correlation between alkaline phosphatase and 25-OHD3 concentration in multiple regression analysis, but no correlation in other variables was found in group of breast milk feeding infants. There was neither correlation between vitamin D concentration and alkaline phosphatase nor other correlated variables in the group of formula milk feeding infants. CONCLUSIONS: In this study, there was a high probability of vitamin D deficiency in the breast feeding infants with a high alkaline phosphatase level. Therefore, it is considered to be worth utilizing alkaline phosphatase as a screening test for vitamin D deficiency or rickets for breast feeding infants.

Cerebral Venous Sinus Thrombosis in an Adolescent Presenting with Headache / 대한소아신경학회지

Cerebral Venous Sinus Thrombosis (CVST) in children is rare and its cause is multifactorial. The clinical manifestations of CVST vary and may cause long-term neurological sequelae and even death on rare occasion. In this case, a 15 year old boy presented with severe headache and vomiting for 1 day. Brain MRI with venography revealed multiple lesions of CVST in superior sagittal sinus and the left transverse sinus. Anticoagulation therapy was performed for 3 months, which led to the complete resolution in superior sagittal sinus and partial resolution in left transverse sinus.

Clinical Review of Children Diagnosed as Specific Language Impairment / 대한소아신경학회지

PURPOSE: The purpose of this study was to evaluate the clinical characteristics of children who had been diagnosed as specific language impairment as outpatients. METHODS: One hundred twenty-five speech- or language-delayed patients were enrolled in Dae-Dong Hospital from July 2007 to June 2008. Fifty-one of 125 children were diagnosed as specific language impairment in whom clinical factors such as duration of therapy and progress after therapy were evaluated. Data were obtained from telephone or direct personal interviews. RESULTS: Among 51 children diagnosed as specific language impairment, 39 (76.5%) had mixed receptive-expressive-type language disorder and 12 (23.5%) had expressive-type language disorder. Thirty children in total were studied as ten children were unavailable for follow-up and eleven dropped out during treatment. The final 30 children consisting of 23 with mixed receptive-expressive type language disorder and seven children with expressive-type language disorder were treated after diagnosis. Total average treatment duration of children with mixed receptive-expressive-type and expressive-type language disorder were 18.1 months and 8.6 months, respectively, a statistically significant difference (P = 0.014). Thirteen (57%) of 23 children with mixed receptive-expressive-type language disorder and all (100%) seven children with expressive-type language disorder completed speech therapy with an average treatment duration of 12.2 and 8.6 months, respectively; however, this difference was not statistically significant(P = 0.287). CONCLUSION: Classifying patients with specific language impairments into mixed receptive-expressive-type and expressive-type language disorder in an outpatient department can be useful for predicting duration of and prognostic effects of language therapy, as our study and other previous articles have shown. More attention is needed from pediatricians to ensure the effective assessment and management of specific language impairment.

Influence of Neonatal Body Surface Area on Decline Rate of Serum Bilirubin Level in Conventional Phototherapy -Neonatal Body Surface Area and the Decline Rate of Serum Bilirubin Level-

PURPOSE: Neonatal hyperbilirubinemia has benign courses in most cases, but the possibility of toxicity of hyperbilirubinemia required courses examination of every newborn infant to identify the severity of hyperbilirubinemia progress. This study aims to see how the body surface area of newborns influences the decline rate of serum bilirubin level in conventional phototherapy. METHODS: Based on the charts of the Pediatrics Department, Dae-Dong Hospital from January 2003 to December 2006, we analyzed 168 neonates diagnosed as neonatal hyperbilirubinemia (serum bilirubin > or =15 mg/dL) in retrospective way. We excluded newborn infants under 37 weeks of gestation and under 2,500 g birth weight and classified neonates into four groups by the calculation results of body surface area:males above 75 percentile (group A), males below 25 (group B), females above 75 (group C), and females below 25 (group D). RESULTS: Out of 168 samples, the number of group A, B, C, D was 30, 20, 20, 15 respectively. In conventional phototherapy, the mean decline rates of serum bilirubin of group B and D recording 2.09 mg/dL/day and 1.77 mg/dL/day, were significantly faster than those of group A and C recording 1.63 mg/dL/day and 1.41 mg/dL/day (P<0.01). No significant differences were found in different duration of phototherapy between groups below 25 percentile and those above 75 in both genders. CONCLUSION: In conclusion, body surface area influences of infants the decline rate of serum bilirubin level in conventional phototherapy.

Investigation of the Influence of Low Birth Weight on the Severity of Asthma in Prealdolescent Children and Aldolescence / 소아알레르기및호흡기학회지

PURPOSE: Over the past several decades, the survival rates of low birth weight(LBW; birth weight <2,500 g) infants have been improving. Many of these infants have had bronchial asthma(BA) at childhood and aldolescence. The aim of this study is to investigate whether LBW influenced the severity of BA in prealdolescent children and aldolescence by a retrospective case control study. METHODS: 15 LBW children(1,500 g

A Case of Familial Clustering of Hepatitis C Virus / 대한소아소화기영양학회지

The familial environment may also play an important role in the epidemiology of HCV infection through vertical and horizontal transmission by infected household members. However, it is still controversial whether familial clustering of HCV occurs. We experienced a case of familial clustering of hepatitis C virus. A 10-year old girl presented with nausea, vomiting and anorexia for a month was diagnosed as hepatitis C. Her mother, grandmother, a maternal aunt and her daughter had contracted with HCV. Her laboratory findings showed AST/ALT 63/122 IU/L, positive anti-HCV Ab and HCV RNA (3.54 x 10(5) copies/mL). Pathologic findings of the liver biopsy revealed chronic hepatitis with minimal lobular activity, mild porto-periportal activity and mild portal fibrosis. After treatment with interferon-alpha 2b for 6 months, the clinical symptoms and laboratory findings were normalized.

Rehospitalization for Respiratory Illness in Very Low Birth Weight Infants during the First Year of Life / 소아알레르기및호흡기학회지

PURPOSE: The aims of this study were to investigate the incidence of rehospitalization for very low birth weight (VLBW) infants due to respiratory illness during the first year of life, and to examine the association between rehospitalization with respiratory distress syndrome (RDS) and duration of mechanical ventilation. METHODS: Twenty-three VLBW infants admitted to neonatal intensive care unit (NICU) at Dae-Dong Hospital from January 1996 to December 2002 were studied. Twenty-three of full-term infants born from January 2001 to December 2002 at Dae-Dong Hospital were studied as control group. Parental questionnaire were collected and hospital records of VLBW infants and control group were reviewed retrospectively. RESULTS: The rate of rehospitalization for respiratory illness in VLBW infants (16/23, 69%) was greater than that of term infants (6/23, 26%) (P< 0.05). Ventilated group with RDS (14/ 19, 73%) in VLBW infants had more rehospitalization compared to non-ventilated group (2/4, 50%) (P< 0.05). Those with ventilator care longer than 7 days (7/7, 100%) had more rehospitalization than those with ventilator care less than seven days (7/12, 58%) (P< 0.05). Fifty nine percent of rehospitalization occurred from December to March. Sixty five percent of rehospitalized infants required admissions between 5 and 8 months after NICU discharge. CONCLUSION: VLBW infants are more likely to have rehospitalization with respiratory illness during first year, especially VLBW infants with RDS and prolonged care of mechanical ventilation. It is important to prevent these susceptible infants from respiratory infections and to follow-up them periodically because VLBW infants tend to show decreased pulmonary function subsequently.

Survey on the Association of the Number of BCG Scars and Atopic Diseases / 소아알레르기및호흡기학회지

PURPOSE: The prevalence of atopic diseases has been increasing remarkably. The less frequent opportunities for infection early in life, especially mycobacteria exposure, parallel this higher prevalence of atopic diseases. Bacille Calmette-Gu rin (BCG), a potent inducer of Th1 immune response, has been suggested to suppress Th2 response which is known to mediate IgE-mediated atopic disorders. This study was done to investigate whether there is any relation between the number of BCG scars and the prevalence of atopic disorders in early childhood. METHODS: We surveyed 393 parents with a children who were given percutaneous multi- puncture BCG vaccination within four weeks after birth. The main questions concerned the past history and present illness of physician-diagnosed atopic diseases (atopic dermatitis, bronchial asthma, and allergic rhinitis), the number of BCG scars (range; 0-18), and potential confounders such as gender, parental atopy, maternal smoking and environmental cofactors. The prevalence rate of each atopic disease was measured and analysed according to the number of BCG scars. RESULTS: Each prevalence rate was 18.1% for atopic dermatitis, 9.4% for bronchial asthma, 14.6% for allergic rhinitis, and 32.3% for any of them. All of them had received BCG vaccination during the first four weeks of life. The children with 15 or more BCG scars had a significantly lower prevalence of any atopic disease (22/99, 22.2%) as compared to those with four scars or less (51/125, 40.8%) by simple regression analysis. (P value=0.02) But this association was not significant after controlling for potential confounders. (P value= 0.26) CONCLUSION: This survey demonstrated a weak relation between a larger number of BCG scars and less atopy development at early childhood. But the relation was not so significant. Further studies are needed.

A Role of Routine Lumbar Puncture in Children Presented with Their First Seizure with Fever / 대한소아신경학회지

PURPOSE: This study was performed to find out the role of routine lumbar puncture in children presented with their first seizure with Fever. METHODS: This study included 220 children, over a 5 year period, from April 1999 to March 2003, who visited or were admitted at Dae Dong Hospital with their first febrile convulsion. Lumbar puncture was performed in all children. We analyzed their age, family history, type of seizure, duration of seizure, cause of fever, and the results of lumbar puncture. RESULTS: In the sex distribution, males(58.6%) outnumbered females(41.4%) and the ratio was 1.2:1. 81.7% of the patients had febrile convulsion from 6 months- to 3 years of age(P<0.05). 30.5% also had family history of febrile convulsion. The types of seizure were generalized tonic-clonic(72.7%), generalized tonic(17.7%), and generalized clonic(6.4 %). For the duration of seizure, 90.4% of the patients were estimated less than 15 minutes(P<0.05). The causes of fever were pharyngotonsilitis(40.5%), gastroenteritis(19.1 %), pneumonia or bronchitis(13.2%), meningitis(11%), otitis media, urinary tract infection, and exanthem subitum. However, 9.1% of the patients were diagnosed meningitis, with 18 of 20 patients under 3 years of age. CONCLUSION: In the first seizure with fever, lumbar puncture is a useful method for meningitis, especially under 3 years of age.

A Case of Familial Hemiplegic Migraine / 대한소아신경학회지

Familial hemiplegic migraine(FHM) is an autosomal dominant subtype of migraine with aura, characterized by the occurrence of hemiplegia during the aura. Two subforms of FHM families exist; pure FHM in 80% and FHM families with cerebellar symptoms in 20%. Half of the known FHM families show genetic linkage to chromosome 19p13, and in these families FHM is caused by missense mutations in a neuronal P/Q type calcium channel alpha-1 subunit gene(CACNA1A gene). Linkages to 1q31 and 1q21-23 have also been established. Other families are linked neither to chromosome 19 nor 1. Clinical variabilities are partially associated with the various types of CACNA1A gene mutations. FHM is distinguished from more frequent migraine types by a clear, dominant inheritance pattern and the relative absense of other headache types. Further investigation of FHM will help to clarify the genetics of more common migraine. We describe a male patient with FHM with a brief review of the literature.

A Case of Ullrich's Disease / 대한소아신경학회지

Ullrich's disease is a congenital muscular dystrophy clinically characterized by generalized muscle weakness, multiple contractures of the proximal joints, and hyperextensibility of the distal joints. All the patients develop rigidity of spine, often assoicated with scoliosis, failure to thrive, and early and severe respiratory involvement, irrespective of their levels of motor function. Intellectual development is normal. The biopsied muscles show dystrophies including remarkable variation in the fiber size, notably proliferated endomysial connective tissues, and a lot of degenerated and regenerated fibers. The expression of merosin and dytrophin is normal. Recent studies have demonstrated that collagen VI is deficient in the muscles of the patients with Ullrich's disease, and some result from recessive mutations of the collagen VIalpha 2 gene(COL6A2). And a marked reduction of fibronectin receptors in the extracellular matrix of skin and cultured fibroblasts of these patients is also reported. These results suggest that collagen VI deficiency may lead to the reduction of fibronectin receptors and that any abnormalities of cell adhesion may be involved in the pathogenesis of the disease. A case of Ullrich's disease has not been reported yet in Korea. So, we describe a male patient with Ullrich's disease with a brief review of the literature.

Analgesic Effect of Sugar Solution in Infantile Colic

PURPOSE: Infantile colic is one of the most commonly encountered problems, characterized by excessive crying in apparently healthy young infants within the first 3 months of life. It is commonly assumed that the infant with colic has distress and possible pain. In recent investigations, it has been found that sucrose has an analgesic effect in newborn infants. The purpose of this study is to examine if sugar solution as sucrose also has an analgesic effect on infant colic. METHODS: This prospective randomized, double-blind placebo controlled study examined healthy term infants aged 4 to 12 weeks with colic. A total of 40 infants were randomly assigned into two groups who visited Daedong Hospital from June 1999 to June 2001. Each group received sugar solution or sterile water. All data from parental diaries and interviews were recorded and analysed blindly. RESULTS: The daily crying time and the colic improvement score were significantly better in sugar solution group as compared with the control(P=0.019, 0.045). No significant differences were noted between groups regarding the number of night wakenings(P=0.173). CONCLUSION: We conclude that sugar solution has an analgesic effect on infantile colic.
