Abstract
The mechanism of heart failure in patients with enterovirus 71 rhombencephalitis (brain stem encephalitis) remains unknown. Our previous reports hypothesized that a catecholamine storm induced by rhombencephalitis may account for the heart failure. The aim of this study was to develop a novel feline model of norepinephrine cardiotoxicity and compare the resulting heart failure to that in children with enterovirus 71 rhombencephalitis. Nine of 75 children (12%) with enterovirus 71 rhombencephalitis (5 boys and 4 girls; age, 4-28 months; median age, 16 months) were complicated with left ventricular hypokinesia (ejection fraction, 31 +/- 9%). Six cats (weight, 3.03 +/- 0.64 kg) were administered intravenous norepinephrine 30 microg/kg/min for 3 hours. Echocardiography assessed the left ventricular diameter and function before and after the administration of norepinephrine. Pathology studies included hematoxylin and eosin stain and in situ terminal deoxyribonucleotidyl transferase-mediated dUTP nick end-labeling assay. In the feline model, norepinephrine induced significant left ventricular dilatation (end diastolic diameter from 1.18 +/- 0.19 to 1.62 +/- 0.22 cm, p = 0.001; endsystolic diameter from 0.54 +/- 0.09 to 1.36 +/- 0.32 cm, p = < 0.001) and hypokinesia (ejection fraction from 87.5 +/- 4.1 to 35.2 +/- 16.3%, p = 0.001). Heart specimens from 4 patients and six cats showed similar pathology findings, including myocardial hemorrhage, cardiomyocyte apoptosis, and coagulative myocytolysis, which is characterized by sarcoplasmic coagulation, granulation, vacuolization, myofibrillar waving, and disruption. Both groups showed no significant inflammatory reaction. In conclusion, heart failure in patients with enterovirus 71 rhombencephalitis is similar to that in cats with norepinephrine cardiotoxicity. Norepinephrine cardiotoxicity may play a role in the pathogenesis of heart failure in enterovirus 71 rhombencephalitis.

Abstract
The Amplatzer duct occluder (ADO) provides a safe and effective therapy for patients with moderate- to large-sized patent ductus arteriosus (PDA), but there have been few reports of transcatheter closure of very large PDAs in young children and infants. We report a successful transcatheter closure of a very large PDA, 10.5 mm in diameter at the narrowest point, with a 14/12-mm ADO. To our knowledge, this is the largest PDA ever closed by an interventional method in such a young child.

Abstract
BACKGROUND Epidemics of enterovirus 71 infection have caused the death of many children throughout the world. Rhombencephalitis, brain stem encephalitis, and heart failure were present in all of the fatal cases. However, no evidence of myocarditis was noted in the heart specimens, and the mechanism of heart failure remains unknown. AIMS To characterise the presentation of cardiac complications in children with enterovirus rhombencephalitis and discuss its pathogenesis. METHODS Ninety one consecutive patients with enterovirus rhombencephalitis underwent echocardiography. Of these, 17 patients (nine male, eight female; median age 14 months, range 4-57 months) with left ventricular dysfunction were studied. RESULTS Tachycardia was noted in all patients and systemic hypertension in 12. Muscle-brain fraction of creatine kinase was >5% in 14 patients. Plasma norepinephrine and epinephrine levels were significantly raised in the three patients in whom these were analysed. Electrocardiographic abnormalities were noted in eight patients. Pulmonary oedema was complicated in 15 patients. The initial ejection fraction of the left ventricle was 22-58% (mean 37%, SD 11%). All patients deteriorated to hypotensive shock within 12 hours and 13 died. Heart specimens from seven patients showed no evidence of myocarditis, but significant coagulative myocytolysis, myofibrillar degeneration, and cardiomyocyte apoptosis were observed. CONCLUSIONS Acute heart failure was noted in 19% of patients with enterovirus rhombencephalitis, which had a fatality rate of 77%. It was not caused by myocarditis but possibly by neurogenic cardiac damage.

Abstract
To establish a noninvasive diagnostic method for early assessment of cardiac involvement in Kawasaki disease (KD), 28 children with KD were included in this study. Two-dimensional echocardiography (2D-Echo) to detect the aneurysms of coronary arteries (CA), as well as rest and dipyridamole-stress technetium-99m tetrofosmin (Tc-TF) myocardial perfusion single photon emission computed tomography (SPECT) to detect abnormal myocardial perfusion were performed in all of the 28 children with KD and to compare each other. The results showed that (1). 42.9% of cases had no aneurysm and 57.1% had significant aneurysms detected by 2D-Echo; (2). 42.9% of cases had normal perfusion and 57.1% of cases had abnormal myocardial perfusion assessed by Tc-TF myocardial perfusion SPECT; (3). 25.0% of cases showed both normal 2D-Echo and Tc-TF myocardial perfusion SPECT findings and 39.3% of cases showed both abnormal 2D-Echo and Tc-TF myocardial perfusion SPECT findings; and (4). there was poor agreement between 2D-Echo and Tc-TF myocardial perfusion SPECT findings (P>0.05). We concluded that poor agreement exists between aneurysms and abnormal myocardial perfusion detected by 2D-Echo and Tc-TF myocardial perfusion SPECT findings in patients with KD.

Abstract
Hemophagocytic syndrome (HPS) in systemic lupus erythematosus(SLE) patients has not commonly been reported. In this case study, we report the first case of Mycobacterium avium complex (MAC)-associated hemophagocytic syndrome in a patient with systemic lupus erythematosus (SLE). This SLE patient, a 15-year-old girl, had been on a high dose of prednisolone (> 0.5mg/kg/day) for more than 3 years. She presented with a spiking fever, hepatosplenomegaly, pancytopenia, hyperferritinemia and adult respiratory distress syndrome. Bone marrow examination revealed hemophagocytosis as well as non-caseating granulomatosis. There was no indication of SLE fare-up. She responded poorly to initial treatment with methyl-prednisolone, intravenous immumoglobulin, etoposide, and drugs for Mycobacterium tuberculosis including rifampin, ethambutol, isoniazid and pyramide. However, gastric lavage culture revealed MAC. Following treatment with clarithromycin, ciprofloxacin and amikacin, her condition gradually improved and she was discharged 3 months after admission. In SLE patients with pancytopenia and hyperferritinemia, MAC-associated HPS should be considered in the differential diagnosis.

Abstract
Isolated sulphite oxidase deficiency (ISOD) is a very rare hereditary metabolic disorder. Imaging findings of the neonatal form of ISOD, including multicystic leukoencephalopathy with brain atrophy, resemble those of severe ischemic changes of the brain. We report the case of a ten-month-old boy who exhibited neonatal seizures on the 24th day after birth. Excessive quantities of sulphite and S-sulphocysteine in the urine and normal blood uric acid were noted. These findings were consistent with those of ISOD. Point mutations were found in two alleles of the sulphite oxidase (SUOX) gene. One of the mutations was a 1029 C > G mutation, which resulted in an amino acid substitution of tyrosine to a stop code (Y343 X); and the other was a 479 G > A mutation, which resulted in an amino acid substitution of arginine to glutamine (R160 Q). Y343 X is a novel SUOX gene mutation. A review of the literature, including data from this report, showed that 3 of 6 cases had typical imaging findings characterized by initial cerebral edema followed by dramatic multicystic leukoencephalopathy. We emphasize that neonatal ISOD should be included in the differential diagnosis of neonates with unexplained hypoxic-ischemic changes on neuroimaging studies.

Abstract
A 2-month-old male baby was admitted to our hospital with episodic cyanosis and respiratory failure which required mechanical ventilation. He was found to have upper limb flexion rigidity and poor weight gain since one month old. Progressive muscle stiffness over the abdomen, chest wall, back and four limbs were also noted. He could not be weaned from the ventilator smoothly due to recurrent CO2 retention. Laboratory tests revealed a high serum creatine kinase level. Cytoplasmic body myopathy was confirmed by muscle biopsy. The unusual initial presentations of generalized stiffness and early onset of respiratory failure were quite different from those of patients reported in the literature, who had floppiness, muscular atrophy and weakness. Prednisolone and Vigabatrin were given and the patient showed slight improvement in muscle stiffness and spontaneous movement.

Abstract
Neonatal hypocalcemia (NH) is common in the neonatal period. Its cause falls into one of two clinical categories, early NH occurs in first 24-48 hours of life; late NH is observed at the end of the first week of life. NH due to congenital hypoparathyroidism, either permanent or transient, is rare. They both present with hypocalcemia, low levels of intact parathyroid hormones, and hyperphosphatemia. In this paper we report on four cases of neonatal hypocalcemia due to transient hypoparathyroidism. They are all full-term infants with normal birth weights, carried by nondiabetic mothers. The age of onset was 6 days old to 17 days old, there were three male and one female. Seizure was the major symptom except for case 2, who had a high pitch crying, irritability and opisthotonus. Laboratory data revealed calcium: 4.7 to 6.3 mg/dl, phosphorus: 6.8 to 9.2 mg/dl, and magnesium: 1.2 to 2.8 mg/dl. The intact parathyroid hormone levels were abnormally low in two cases (<13 pg/ml and 5.7 pg/ml), yet only subnormal in the other two (25.2 pg/ml and 22.2 pg/ml). Further studies on these four babies showed no evidence of Di George syndrome. Interestingly, two patients' mothers were found to have hyperparathvroidism. In conclusion, in case of neonatal hypocalcemia, measurements of calcium, phosphorus, and intact-PTH in neonates are required to recognize hypoparathyroidism. Pediatricians should always check maternal parathyroid status to rule out maternal hyperparathyroidism.

Abstract
Twenty-three patients with growth hormone deficiency (GHD) followed until their final heights (FH) were reported by retrospective review. Seven patients had spontaneous puberty (group 1) and sixteen required induction of puberty (group 2). Their heights prior to growth hormone (GH) therapy were -3.7 +/- 1.4 and -2.8 +/- 1.4 SDS in men and women respectively. The mean ages at initiation of GH therapy were 17.2 +/- 3.3 in men and 13.0 +/- 1.7 years in women, with a growth velocity < 4 cm/year and a mean bone age (BA) of 12.6 +/- 0.7 years (men) and 9.8 +/- 1.2 years (women). The dose of GH was 0.27-0.83 IU/kg/week, with a total duration of 2.5 +/- 1.0 years. Their consecutive annual mean growth velocities on GH therapy were: 10.6 cm/year, 8.0 cm/year, 6.1 cm/year, 5.1 cm/year and 4.6 cm/year respectively. They reached a mean final height of 167.1 +/- 5.3 cm (-0.4 +/- 1.0 SDS) in men and 157.9 +/- 3.5 cm (-0.1 +/- 0.7 SDS) in women, which is slightly taller than their target height. Demographic factors related to growth response and final heights were analyzed. We conclude that GH therapy is very effective in linear growth promotion. Their final height was correlated with initial height SDS, target height SDS, predicted adult height SDS according to the bone age at the start of GH therapy and height SDS at the onset of puberty.

Abstract
Isosexual precocious puberty in girls is not uncommon, but its association with craniopharyngioma and growth hormone deficiency is rarely reported. We present a patient with this combination. An 8-year-old girl developed breasts and then had menarche at 7 9/12 years old. Growth hormone deficiency was suspected due to inappropriate height and growth velocity in association with idiopathic precocity and a poor predicted adult height of 138.8 cm. Growth hormone deficiency was confirmed by clonidine and insulin stimulation tests. Intracranial lesion was suspected due to precocity associated with GH deficiency. MRI of the sella's region revealed a 1 cm mass in the hypothalamus. After surgical resection, pathology of the tumor disclosed a craniopharyngioma which has rarely been reported to cause precocious puberty. The precocious puberty regressed after surgery. Growth hormone deficiency persisted and GH therapy was given to improve growth. The growth rate of patients with both growth hormone deficiency and precocious puberty may be maintained within the normal prepubertal range by the effect of sex steroid. We suggest that in patients with central type precocity in association with an inappropriate growth status, physicians should investigate the underlying intracranial lesion, and the possibility of growth hormone deficiency.

Abstract
We report a case of systemic sclerosis, limited type, in a 5 year old boy in Taiwan. He presented with erythema, tight skin over his face and digits, subcutaneous calcification, telangiectasis, as well as Raynaud's phenomenon. The laboratory data showed weakly positive antinuclear antibody (ANA), and Topoisomerase 1 antibody (anti-Scl-70) titers. However his esophagogram, CO diffusion capacity, as well as cardiac and renal function were all normal. He suffered from the skin change for 2 to 3 years before visiting our pediatric clinic when he was 7 years old. We gave him Dipyridamole, D-penicillamine, Colchicine, and Nifedipine. There was some remission of the scleroderma and Raynaud's phenomenon after our treatment.

Abstract
Thirty-one physicians, 108 nurses, 105 medical students, and 126 student nurses practicing in the same medical center received a questionnaire to evaluate their knowledge and attitudes about breastfeeding. The mean knowledge score of the 139 staff member was 49.4 +/- 10.8 (The highest possible score was 73); that of the medical students was 31.2 +/- 8.9, and that of the nurse students was 39.5 +/- 7.6. Thirteen percent of the medical students vs. 68.6% of the student nurses reported that they had received breastfeeding education in school. All of the respondents had a positive attitude toward breastfeeding. Occupation and in-service education for breastfeeding could increase the knowledge score. Having been breastfed during infancy could increase both the knowledge score and positive attitude score. We suggest that breastfeeding be integrated into the curricula of both medical and nursing schools. Health professionals should receive in-service education. The mechanism of lactation, management of breast problems and infant problems, contraindications for breastfeeding, the properties of human milk and the benefits of breastfeeding for the infant should all be included.

Abstract
The clinical manifestations of delayed neuropsychiatric sequelae after carbon monoxide (CO) intoxication are variable. In addition, there is no specific therapy for these complications. Fortunately, these complications have occurred less frequently in recent years, probably due to the usage of hyperbaric oxygen (HBO) therapy. We report an 8-year-old boy who developed late psychiatric disturbances 2 days after full recovery of consciousness from initial CO intoxication. His neuropsychiatric symptoms included consciousness disturbance, motor dysfunction, chorea, aphasia and agnosias. He received HBO therapy at 2.0 barr for 60 minutes once a day for 7 consecutive days. Three weeks later, he was functioning normally with no neuropsychiatric symptoms. A literature review concluded that HBO may be effective in treating neuropsychiatric sequelae. Moreover, immediate administration of HBO during acute CO intoxication may prevent these complications.

Abstract
BACKGROUND Kawasaki disease is a common acquired heart disease in children. Only a few reports have been published concerning Kawasaki disease in infants. This study was performed to assess the clinical spectrum of Kawasaki disease in infants. METHODS Between January 1989 and December 1998, a total of 48 consecutive Kawasaki patients less than one year of age were enrolled and studied retrospectively. Coronary artery dilation was defined as the internal diameter of a coronary artery larger than 3 mm. All cases received 2 gm/Kg of intravenous immunoglobulin. We divided the patients into two groups; group I; coronary artery dilation (+) and group II; coronary artery dilation (-), and compared the clinical and laboratory data. RESULTS Of 273 patients with Kawasaki disease, 48 (17.5%) were less than one year of age. Among these patients (< 1 year old), the median age was 7.8 +/- 2.8 months (range 2 months to 12 months), and the male to female ratio was 1.52:1. The incidence of atypical Kawasaki disease was 31.2% (compared with an incidence of atypical Kawasaki disease among patient more than one year of age of 7.5%; p < 0.001), and that of coronary artery dilation was 35.4%. Clinical manifestations included fever 100%, extremity change 91.6%, skin rash 89.6%, conjunctivitis 89.6%, oral mucosa change 89.6%, and cervical lymphadenopathy 0%. Laboratory data revealed white blood cell count: 15,403 +/- 6,282/mm3, hemoglobin: 10.1 +/- 1.0 gm/dl, neutrophil: 59.2 +/- 13.7%, lymphocytes: 30.6 +/- 13.1%, platelet count: 456,3000 +/- 216,4000/mm3, and C-reactive protein 8.2 +/- 5.6 mg/dl. Patients with coronary artery dilation had a longer duration of diagnosis, higher incidence of atypical presentation, lower incidence of conjunctivitis, lower incidence of skin rash, lower incidence of extremity change, and lower C-reactive protein. The predictive value of coronary artery dilation based on the combination of atypical presentation, duration of diagnosis, and C-reactive protein was 81.2%. CONCLUSIONS Kawasaki disease in infants is associated with a high incidence of atypical presentation and increased risk of coronary artery dilation. We suggest that in an infant with insufficient diagnostic criteria for Kawasaki disease, care should be taken to avoid missing atypical Kawasaki disease. Echocardiography is an important tool for diagnosis of atypical Kawasaki disease.

Abstract
PURPOSE Accurate evaluation of the size, location and adjacent structure of an atrial septal defect (ASD) is very important in the selection of patients for further management. We directly compared the utility of transthoracic echocardiography, angiocardiography, balloon sizing, and intracardiac ultrasound (ICUS) in the detection of ASD. METHODS Twenty-one children underwent an ICUS study of ASD after routine clinical and laboratory studies. All patients had received transthoracic echocardiography (TTE), cardiac catheterization, cineangiography, and balloon sizing before the ICUS to evaluate the ASD. RESULTS There was a significant correlation between the ICUS-derived ASD diameter and the other methods (p < 0.001). The balloon-sizing diameter was estimated by the equation: TTE diameter x 1.09 + 3.9 mm. There was a good correlation between the predicted and measured balloon-sizing diameter (r = 0.963; p < 0.001). CONCLUSION It is worthwhile spending a few minutes to perform ICUS during cardiac catheterization since it will provide more detailed information on and high resolution images of atrial septal morphology, especially for patients undergoing transcatheter closure by device.

Abstract
Two children with an anomalous origin of one pulmonary artery from the innominate artery are reported. One was a 15-month-old boy presenting with respiratory distress. He had a right aortic arch and his left pulmonary artery originated from the innominate artery. The other was a 1-month-old girl presenting with congestive heart failure. She had a left aortic arch and her right pulmonary artery originated from the innominate artery. An understanding of the embryological pathogenesis of these anomalies has significant therapeutic implications.

Abstract
Congenital complete heart blocks (CCHB) are mostly related to the neonatal lupus syndrome. The purpose of this paper was to assess the clinical spectrum of CCHB in our hospital. Nine patients were retrospectively enrolled between 1994 and 1999. The birth history, electrocardiography, 24-hour Holter monitoring, pacemaker insertion and its complications, maternal disease, and maternal and infant autoantibody levels were studied. All nine cases were diagnosed prenatally. Hydrops fetalis was noted in five (55.6%). Six cases were live births and the other three were terminated. No anatomical heart defects were noted. Initial electrocardiography revealed the atrial rates ranged from 150 to 166 beats per minute. The minimal ventricular rates ranged from 46 to 80 beats per minute. VVI mode pacemakers were inserted through xyphoid approach in all live-birth infants. Complications were noted in three of them (50%). Antinuclear antibody and anti-SSA/Ro antibody were positive in all 8 mothers (100%). The anti-SSB/La antibody was positive in 6 of the eight mothers (75%). Five infants tested positive for anti-SSA/Ro antibody. None of the infants tested positive for anti-SSB/La antibody. In conclusion, all CCHBs in our series were associated with maternal autoantibodies. Because of high complication rate of permanent pacemaker insertion during the neonatal period, it should be restricted in certain conditions.

Abstract
Zellweger syndrome is a fatal autosomal-recessive hereditary disease characterized by the absence of peroxisomes in liver and kidneys. The absence of peroxisomes results in impairment of many metabolic pathways, especially beta-oxidation of very long chain fatty acids (VLCFAs). We report a case of a three-month-old male infant with facial dysmorphism, hypotonia, psychomotor retardation, and hepatomegaly. He had an elder brother with the same facial features and hypotonia who died of hepatic failure at four months of age. Biochemical studies revealed elevation of blood pipecolic acid and VLCFAs, compatible with peroxisomal disorder. Electron microscopy of liver biopsy revealed absence of peroxisomes. Zellweger syndrome was diagnosed. Because this syndrome is usually fatal in early life, genetic counseling and prenatal diagnosis are crucial.

Abstract
Hansenula anomala, an ascosporogenous yeast of the class Ascomycetes, is a free-living organism isolated from the environment. It is also a part of the normal or transient flora of the human throat and alimentary tract. It has been recognized as an opportunistic pathogen and its infection is very rare. A premature infant, a victim of right femoral osteomyelitis and right hip arthritis caused by oxacillin-resistant Staphylococcus aureus, was found to have developed H. anomala fungemia just before the initiation of the antimicrobial therapy with teicoplanin. Antifungal agents (fluconazole and amphotericin B) were prescribed for 10 days despite the absence of clinical sign of systemic fungal infection. His general condition remained good, with a subsequent sterile blood culture. The patient was discharged after completing 5 weeks of antimicrobial therapy, and he remained well during follow-up at our outpatient clinics. Here, we also review the risk factors, the clinical presentations, and the therapeutic strategies of H. anomala infection in the literature.

Abstract
BACKGROUND Tetralogy of Fallot (TOF) with subpulmonary ventricular septal defects (VSD) is relatively more common among Orientals than among Occidentals. This study assessed the influence of type of VSD on surgical results in children with TOF. METHODS Fifty-one patients with TOF (age range, 14 months to 11 years, mean 40.7 months, median 30 months, 29 boys, 22 girls) who underwent total correction by a single surgeon between January 1992 and December 1995 were retrospectively studied. Of the 51 patients, 17 patients with subpulmonary VSD were classified as group I. The remaining 34 patients with perimembranous VSD were classified as group II. All patients underwent a combined transatrial and transpulmonary surgical approach. Early postoperative results were evaluated 7 to 10 days after surgery and late postoperative results were evaluated 1 year after surgery. RESULTS There were no statistically significant differences between the two groups in age, sex, body weight, pulmonary to systemic flow ratio, pulmonary to aortic annulus diameter ratio or preceding palliative shunt or balloon pulmonary valvuloplasty. Nevertheless, group I patients had better oxygen saturation preoperatively (84.2 +/- 4.4% vs 80.3 +/- 7.6%, p = 0.037). During surgery, the transannular patch rate was higher in group I (100% vs 73.5%, p = 0.003). The cardiopulmonary bypass time, postoperative stay in the intensive care unit, duration of chest tube placement, early postoperative residual VSD rate, and early and late postoperative residual pulmonary stenosis rate were not significantly different between the groups. However, late postoperative residual VSD rate was 33.3% in group I and 6.45% in group II, which was statistically significant (p = 0.029). There were no significant differences in arrhythmia between the two groups. CONCLUSIONS Patients with TOF with subpulmonary VSD had a better preoperative oxygenation, higher transannular patch rate during surgery and a higher incidence of late residual VSD than those with TOF with perimembranous VSD.

Abstract
Lesch-Nyhan syndrome is an X-linked recessive disorder involving the purine metabolism, with resultant hyperuricemia, choreoathetosis, self-mutilation, and profound neurologic dysfunction. A deficiency of the enzyme hypoxanthine guanine phosphoribosyl-transferase is responsible for the disease. The human HPRT gene is located at Xq26-27 and consists of 57 base pairs. At least 2,000 mutations throughout the HPRT gene coding region from exon 1-9 have been reported. Four patients from three Chinese families were diagnosed with Lesch-Nyhan syndrome according to the clinical and laboratory findings. DNA studies revealed the first family (Patients 1 and 2) had a missense mutation in exon 3 of the HPRT encoding region. This novel mutation occurs in the hot spot of the HPRT gene. The second family (Patient 3) was found to have a missense mutation in exon 8 of the HPRT gene. The third family (Patient 4) carried a mutation in the splicing region of intron 4 of the HPRT gene. All three mutations were de novo.

Abstract
We carried out a retrospective study on childhood invasive pneumococcal infections (IPI) diagnosed from the January 1990 through the April 2000 at a medical center in central Taiwan. Their clinical features, outcome of the patients and the resistance patterns of the isolates were analyzed. A total of 95 clinical isolates from 72 patients younger than 14 years of age were included in this study. Of these 72 patients, 51 had bacteremia, 28 meningitis, 14 bacteremic pneumonia, 12 pleural empyema, eight otitis media, four arthritis, three sinusitis, two periorbital abscesses, one deep neck infection, one psoas muscle abscess, one peritonitis, one urinary tract infection, and one cutaneous infection. Ancillary diagnostic tests, including Gram stain smears and latex agglutination tests, were applied and the sensitivities were 86.2% and 54.3%, respectively. The prevalence rate of penicillin nonsusceptible Streptococcus pneumoniae has increased dramatically since 1995 in central Taiwan, with rates of 5.6% and 74.1% before and after 1995, and the overall mortality rate was 20.8% and 53.3% respectively. Ten of 19 children (52.6%) with pneumococcal meningitis who survived had long-term sequelae.

Abstract
BACKGROUND An outbreak of hand-foot-and-mouth disease caused by enterovirus infection occurred in Taiwan in 1998 and more than 70 infants and children with fulminant courses died. We compared the cardiac manifestations of fatal cases with patients who survived the enterovirus infection. METHODS A total 187 patients with enterovirus infection were treated at Taichung Veterans General Hospital between April and June 1998. Enterovirus infection was diagnosed by history, clinical features, polymerase chain reaction study and/or viral culture. Cardiac examinations including complete physical examinations, electrocardiography and echocardiography were performed on seven cases (group I) with or without central nervous system (CNS) involvement, 30 patients with CNS involvement (group II), and 150 patients without CNS involvement (group III). RESULTS There were no significant differences in sex distribution, days of fever, heart rate, systemic blood pressure or time from the onset of symptoms to hospital admission among the three groups. All group I patients had features of acute congestive heart failure, pulmonary edema and neurologic signs except one who presented with right-sided heart failure and neurologic signs. The echocardiographic findings of group I were a lower fractional shortening, lower ejection fraction, and more severe and higher incidence of mitral regurgitation (p < 0.01) than in groups II and III, but there were no significant differences in end-systolic wall stress, left ventricular end-diastolic internal dimension and incidence of pericardial effusion among the three groups. CONCLUSIONS We conclude that seven infants and children (group I) died due to either severe cardiomyopathy or encephalopathy. The possible pathogenesis of enterovirus infection leading to death is reviewed and analyzed.

Abstract
Two parts are included in this article. First, to improve the training course in pediatric advanced life support (PALS), we held a 2-day PALS training course on March 28 and 29, 1999. A pretest, posttest, and survey questionnaire were given to each participant. Of the 143 participating in the 2-day PALS course, 137 completed the study. The mean pretest score was 70.2 (SD = 11.5) and the mean posttest score was 86.9 (SD = 9.1). There was significant improvement noted after the 2-day PALS training course (p < 0.001). The 2-day PALS training course resulted in greater improvement in scores compared with the previous 1-day PALS training course in some certain groups of participants. The number of participants complaining that they were too rushed to get the best learning result declined from 71 of 106 (66.3%) taking the 1-day training course to 43 of 137 (31.4%) taking the 2-day training course. Second, a same written test was given to the 129 participants who had finished a 1-day PALS training course one year previously to evaluate the participants' retention of knowledge after 1 year. Of 82 responders who took the 1-year follow up test, 75 were from the medical center. The score of the follow-up test for these 75 participants showed a significant decline when compared with the posttest, except for those receiving another training course of advanced life support during the follow-up year. We conclude that the 2-day PALS training course is better than the 1-day PALS training course. Those who participate in the pediatric critical or emergent care had better receive the 2-day PALS training course. The participants receiving the 1-day PALS training showed a significant decline in their knowledge after 1 year, and they should reinforce their knowledge in the following years.

Abstract
Chronic granulomatous disease (CGD) is a rare inherited disorder caused by defects in the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex of phagocytic leukocytes. The leukocytes of the CGD patients cannot produce adequate amount of superoxide and other oxygen metabolites which are toxic to microorganisms. As a result, the phagocytes fail to kill the ingested microorganisms, especially those with catalase activity. Typically, CGD patients suffer from recurrent pyogenic infections starting from the first year of life. We report a young boy who had experienced recurrent perianal abscess, osteomyelitis and bacterial enterocolitis. Flow cytometric analysis revealed defects in the neutrophil respiratory burst pathway and defined the carrier state of his mother and younger sister. He received antimicrobial prophylaxis at our out-patient clinics and remained well at present. We try to make clinical physician keep in mind the diagnosis of CGD by presenting this typical case. In the meantime, we review the recent literature regarding the advances in diagnosis and management of CGD.

Abstract
Barrett's esophagus, a premalignant condition, is recognized as stratified squamous epithelium of the esophagus substituted by columnar epithelium. The risk factors for development of Barrett's esophagus include frequent gastroesophageal reflux, esophageal stricture, male sex and mental retardation, but there is no report of Barrett's esophagus in children with de Lange syndrome. We report a 7-year-old boy who was diagnosed as de Lange syndrome shortly after birth and had gastroesophageal reflux since early infancy. Upper gastrointestinal endoscopic examination revealed a cauliflower-like mass and a pink-red velvety mass over the lower third of the esophagus. Biopsy showed goblet cells metaplasia, confirming Barrett's esophagus. We suggest surveillance of Barrett's esophagus could be done ahead of schedule in children with long-standing gastroesophageal reflux or with de Lange syndrome.

Abstract
About 4% of children with Kawasaki disease ultimately develop ischaemic heart disease. Therefore, the early detection, non-invasive monitoring and long-term follow-up of myocardial ischaemia are essential. We compared the sensitivity and specificity of 201Tl single photon emission tomography (SPET) and treadmill exercise in the detection of myocardial ischaemia in 23 patients (19 boys, 4 girls) with Kawasaki disease. They were divided into two groups according to the results of coronary angiography. Group I consisted of 11 patients with coronary abnormalities; Group II consisted of 12 patients with no coronary abnormalities. The sensitivity, specificity, false-positive and false-negative rates for detecting coronary arterial lesions were 72.7% (8/11), 58.3% (7/12), 38.5% (5/13) and 30% (3/10) for 201Tl SPET, and 45.5% (5/11), 100% (12/12), 0% (0/5) and 33.3% (6/18) for treadmill exercise, respectively. We conclude that 201Tl SPET is more sensitive than treadmill exercise for the detection of coronary arterial abnormalities, but that the specificity of treadmill exercise is better than that of 201Tl scintigraphy. Coronary artery lesions detected by coronary angiography have good concordance of ischaemic areas with perfusion defects detected by 201Tl SPET. When ischaemic findings on 201Tl SPET and/or positive treadmill exercise testing are noted, coronary angiography is strongly indicated to detect possible stenotic lesions in the coronary arteries.

Abstract
The principal viruses implicated in pericarditis are enteroviruses. Cytomegalovirus pericarditis is quite rare and has been reported in immunocompromised patients with acquired immunodeficiency syndrome, malignant neoplasm or organ transplantation. We report a three-month-old male infant who suffered from cough and rhinorrhea for two weeks. He developed shortness of breath for three days, and fever for one day, prior to admission. Physical examination revealed tachycardia, tachypnea, pale conjunctiva, hepatomegaly, and a muffled heart sound without significant murmur. Chest radiography showed marked enlargement of the cardiac silhouette. Echocardiography demonstrated a large amount of pericardial effusion with impaired diastolic ventricular function. After pericardial drainage and supportive treatment, the fluid gradually disappeared. Viral culture of the pericardial fluid and serologic data confirmed a cytomegalovirus infection. Cytomegalovirus pericarditis should be included in the differential diagnosis of pericardial effusion in a young infant.

Abstract
In order to survey both the epidemiology of nosocomial infection in our neonatal intensive care unit (NICU) and the changing face of nosocomial infection after the introduction of National Health Insurance (NHI) in Taiwan, we retrospectively reviewed the nosocomial infections which occurred in our NICU from March 1, 1991, to February 28, 1999. We also compared the nosocomial infections from the viewpoint of NHI. The mean rate of nosocomial infections in our NICU during these 8 years was 13.6%, and it had significantly increased after the NHI plan was implemented (from 7.9% to 19.0%). The most common type of nosocomial infection was blood stream infection (53.8%, 120 of 223 infections). Coagulase-negative Staphylococci and fungi were the two most common pathogens of nosocomial blood stream infection in our NICU, accounting for 28.1% and 24.2% of the infections, respectively. The survival rate of very low birth weight (VLBW) infants increased from 76.3% to 78.4% after the implementation of NHI. However, the nosocomial infection rate of the VLBW infants had markedly increased from 22.6% to 41.9%. The total number of hospitalization days of the patients with nosocomial infection was significantly greater than that of those without nosocomial infections (p < 0.05), and the patients with the lower birth weights had longer hospital stays. The risk factors for nosocomial infection including invasive procedures, multiple and empirical antibiotics, and extremely low birth weight premature infants, remained the same, but the prevalence of nosocomial infection in the neonatal intensive care unit has changed markedly since the NHI plan began. Further investigation to determine strategies for preventing nosocomial infection in very low birth weight infants is warranted.

Abstract
With recent advances on newborn intensive care, the survival rate of very low birth weight preterm infants has been improved. The consequently new morbidities such as learning disabilities, behavioral problems, lower mean IQ and motor clumsiness have become more frequent. Neonatal individualized developmental care seeks to read the behavior of premature infants, and pace our procedures and caregiving according to individual infant's cues. Studies have shown that with implementation of developmental care, the time spent on ventilator and hospitalization was decreased, and infants started oral feeding earlier. The short and long-term neurobehavioral outcomes were improved. Developmental care focuses not only on changing the environment to provide a calming and soothing environment for the infants and family, but also provides a chance for all the staff members to read the behavior of the infants, think and reflect before doing something to the infants.

Abstract
The study is to evaluate the effect of levamisole on steroid-sensitive nephrotic syndrome (SSNS) children with multiple relapses, from October 1996 through December 1998, we prospectively recruited 27 SSNS children. Eight children had minimal change nephrotic syndrome and nine had mesangial nephropathy proven by renal biopsy. The other 10 children had normal renal function and no secondary cause of nephrotic syndrome (NS). Nine were frequent relapsers (FR), (> 4 attack per year), nine were steroid-dependent (SD), and another nine were both FR and SD. The dosage of levamisole given was 2 to 3 mg/kg daily or every other day, depending on the patients' response. All were followed regularly at outpatient department. Follow-up items included a routine urinalysis every month, complete blood count (CBC) every 3 months and BUN/Cr, AST/ALT every 6 months. After 6 to 24 (mean 12.2) months of follow-up, the frequency of relapse (FoR) decreased (5.74 +/- 3.24 vs 1.91 +/- 2.0/year p < 0.05). Seven (26%) had no relapse at all. Nine (33.3%) had less than 1/3 the FoR; four (14.8%) had 1/3 to 1/2 the FoR; and seven (26%) still had more than 1/2 FoR as before levamisole. The oral prednisolone dosage also decreased (0.62 +/- 0.42 vs 0.21 +/- 0.35 mg/kg/day, p < 0.05). The levamisole response was independent of the age of NS onset, the interval between NS onset and initiation of levamisole, previous number of relapse, the FoR, and previous use of cytotoxic drug. There were 7 episodes of leukopenia, which returned to normal after discontinuing levamisole for 1 to 2 weeks in 4 patients. Two (7.5%) had reversible leukopenia for more than 4 weeks. No abnormal BUN/Cr, or ALT/AST levels were noted during follow-up. Levamisole is an effective and safe drug for children who have SSNS with FR and/or SD. Two thirds of patients obtain satisfactory control. The dosage can be 2 to 3 mg/kg daily or every other day. The most common side effect is transient leukopenia.

Abstract
Congenital muscular dystrophy (CMD) is a rare heterogeneous disease found in the oriental population, especially the occidental type of CMD. We report a case of a one-year-old infant who presented with early onset hypotonia, muscular weakness, delayed motor development and normal intelligence. A muscle biopsy revealed dystrophic muscle fibers. A high creatine kinase (CK) level, mostly of the MM type, was also noted. Further study of brain images showed hyperintense lesions in the white matter area. The patient showed the clinical and laboratory findings characteristic of CMD, more likely to be of the occidental type. Further genetic or histopathologic studies, especially merosin investigation, are suggested for improved classification and prognosis prediction.

Abstract
The modified Blalock-Taussig (B-T) shunt is well recognized as a palliative procedure for cyanotic congenital heart disease in infants. Pseudoaneurysm formation after a modified B-T shunt is a rare complication. We present the case of a 9-month-old girl with tetralogy of Fallot who had undergone a modified left B-T shunt at 5 months of age and developed a pseudoaneurysm after an episode of infective endocarditis as detected by echocardiography. Compression of the left bronchus, displacement of the mediastinum to right chest, and paralysis of the left hemidiaphragm were found. Magnetic resonance images, computed tomography scans, aortograms, and selective angiograms demonstrated the presence of a large pseudoaneurysm. The compression syndrome gradually disappeared after aneurysmectomy.

Abstract
From July 1997 to June 1998, 25 preterm infants (birth weight < 1800 g) were included in a prospective study to compare the clinical effects of breast- and bottle-feeding. Oxygen saturation, heart rate, respiratory rate, and body temperature were recorded every minute for 20 minutes during feeding periods. Eighty pairs of breast- and bottle-feeding sessions were observed at the chronological age of 9.3 +/- 4.3 (range = 2.1-25.3) weeks. Oxygen saturation and body temperature of the preterm infants were significantly higher when they were directly breastfed. There were 2 episodes of apnea (breath pause more than 20 seconds) and 20 episodes of oxygen desaturation (PaO2 < 90%) during bottle-feeding and none during breastfeeding. We conclude that breastfeeding is a more physiological feeding method for the preterm infant and bottle-feeding may be more stressful.

Abstract
From September 1989 to August 1996, we performed anterior corpus callosotomy in 83 patients. Unfortunately, 9 patients were lost to follow-up. Among the remaining 74 patients, 59 had Lennox-Gastaut syndrome (evolved from infantile spasms in 22), 9 had complex partial seizures with or without secondary generalized seizures, 1 had multifocal independent epileptogenic foci (MISF) syndrome, 3 had hemiconvulsion-hemiplegia-epilepsy (HHE), and 2 had infantile spasms. All cases were followed up for at least 2 years after surgery. The highest rate of significant improvement (more than 50% reduction in seizure frequency) was noted in the patients with generalized tonic-clonic seizures, 82.1% of whom experienced significant improvement, followed by those with generalized tonic seizures (76. 7%), atonic seizures (72.7%), myoclonic seizures (64.9%), atypical absences (58.6%), and complex partial seizure with or without secondary generalization (61.5%). Complete freedom from seizures was noted in 14 cases (18.9%). One patient had the anterior half of his right palm amputated following radial artery thrombosis complicated by insertion of an arterial line during anesthesia. Otherwise, there were no major postoperative complications except for brief mutism and multifocal jerks in some patients during the 1st postoperative week. Thus, we conclude that corpus callosotomy is a safe alternative treatment for all kinds of medically intractable seizures, especially generalized epilepsy.

Abstract
Thirteen children with refractory epilepsy received a ketogenic diet (medium chain triglyceride oil diet) as an alternative therapy since September 1997. Their seizure patterns included (1) generalized tonic-clonic seizures, (2) myoclonic seizures, (3) generalized tonic + atonic seizures, (4) complex partial seizures, (5) generalized clonic + atonic + myoclonic seizures, (6) head nodding + myoclonic + gelastic seizures, and (7) generalized tonic-clonic + myoclonic + atonic seizures. Major concerns emphasized on the efficacy and side effects of the diet. Clinical observation one month after the diet revealed that 53.8% of the patients had a > 75% reduction in seizure frequency and 76.9% of the patients had a > 50% reduction in seizure frequency. Six patients had some degrees of improvement in cognitive function and/ or school performances. The most common side effects were body weight loss (n = 6) and diarrhea (n = 5). Others included bad temper (n = 1), abdominal cramps (n = 2), nausea (n = 2), bad body smell (n = 1), and renal stones (n = 1). Even after discontinuation of the diet, 61.5% of patients still had a > 50% reduction in seizure frequency. We concluded that the ketogenic diet deserves a trial in children with refractory epilepsy.

Abstract
Many papers have reported that twin pregnancies with one twin demise in the uterus can cause complications in the surviving twin. We retrospectively reviewed charts from 1988 to 1997 at our hospital and found 17 of 302 twin deliveries with one twin intrauterine fetal death. The incidence of intrauterine death of a single twin was 5.7%. Six of the surviving twin (35.3%) had renal function impairment. One died due to acute renal failure. The other five patients recovered normal serum creatinine level. Five patients (29.4%) had abnormal brain imaging findings. One had multicystic encephalomalacia and microcephaly. Three of the five patients were complicated with cerebral palsy. After dividing the patients into complicated (n = 8, 47.1%) and non-complicated (n = 9, 52.9%) groups, we found that the patients with complication had lower Apgar score at 5 minutes and those with monochorionic diamniotic placenta had higher incidences of complication (62.5% vs 12.5%). We conclude that twin pregnancies with one fetal demise in the uterus do result in a higher incidence of complication in the surviving twin, especially if placentation type is monochorionic diamniotic. In managing the surviving twin of the monozygous twin pregnancies with one fetal demise in the uterus, we must be careful to monitor these patients. If complication was suspected, we should arrange the brain and kidney ultrasonography and manage these patients appropriately to decrease the complication risk.

Abstract
To improve the preparedness of health care providers in pediatric resuscitation and to evaluate the effectiveness of the Pediatric Advanced Life Support course, we followed the standard guidelines of American Heart Association to conduct the first 10-hour course of Pediatric Advanced Life Support course in our hospital and designed this study. A total of 160 doctors and nurses were enrolled in the providers course held on Jan. 11, 1998. A pretest, posttest and survey questionnaire were given to each participant. One hundred and twenty-nine completed these tests. The average scores were 73.1 for the pretest and 86.8 for the posttest. The average scores on the pretest and posttest among doctors (n = 57) and nurses (n = 72) are 72.6, 86.7 and 73.5, 86.8, respectively (p < 0.001). In the participants with pretest score of less than 80 (n = 92), the mean values of pretest and posttest scores were 69.0 and 86.4. The participants with pretest scores higher than or equal to 80 (n = 37) had pretest and posttest mean values of 83.3 and 87.7. The participants with less background knowledge (pretest < 80) had better increment scores after this course (p < 0.05). The mean posttest scores in those working in private clinics and having 20 years of working experience are 74.0 and 72.0 (lower than the criteria for successful completion of written examination). We conclude that this provider course did increase the knowledge and skill pertaining to pediatric resuscitation personnel, particularly in participants with less background knowledge. The participants from private clinics or with working experience more than 20 years need a repeatedly educational PALS training course.

Abstract
An 11-year-old boy presented with seizure and cortical blindness. A T1 weighted magnetic resonance image of the brain showed high signal intensity in the bilateral corpus striatum and long T1 and T2 changes in the bilateral occipital and cerebellar hemispheric regions. Increased cerebrospinal fluid lactate concentration of 56.7 mg/dl and blood lactate concentration of 34.2 mg/dl were also noted. A muscle biopsy obtained from the quadriceps femoris muscle showed the presence of ragged red fibers and mitochondrial DNA (mtDNA) analysis showed an A-->G mutation at nucleotide position 3243. MtDNA analysis of the patient's mother revealed the same mutation. These findings indicated MELAS syndrome (mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes).

Abstract
UNLABELLED Intratumoral injection of 90Y microspheres is a potential alternative in the treatment of primary liver tumor. However, complicated preparation and lack of a gamma ray for imaging are the disadvantages of 90Y. In this study, we used 188Re, a generator-produced radioisotope with 155-keV gamma ray emission, to label microspheres. After intratumoral injection of 188Re microspheres into rats with hepatoma, biodistributions and survival times were analyzed. METHODS Twelve male rats with hepatoma were killed at 1, 24 and 48 hr (4 rats at each time point) after intratumoral injection of approximately 7.4 MBq 188Re microspheres. Samples of various organs were obtained and used to calculate the tissue concentrations. In addition, 30 male rats bearing hepatoma were divided into two groups (15 rats in each group) to evaluate survival time. Group 1 received intratumoral injection of 37 MBq 188Re microspheres, whereas Group 2 served as the control group and received an intratumoral injection of 0.1 ml normal saline only. Survival time was calculated from the day of injection to 2 mo after treatment. RESULTS Radioactivity in the tumor was very high throughout. Biological half-time was 170.8 hr. Radioactivity in the lung was 1.78% injected dose (i.d.)/g at 1 hr but declined rapidly over time. The concentration in the urine was approximately 6.14% i.d./ml after the first hour and rapidly declined thereafter. The concentrations of radioactivity in other organs, such as normal liver, muscle, spleen, bone, testis and whole blood, were quite low throughout the study. Twelve of 15 (80%) of rats survived over 60 days after intratumoral injection of 188Re microspheres, whereas only 4 of 15 (26.7%) survived more than 60 days after injection of normal saline only. The difference between the groups was significant (p < 0.05). CONCLUSION Rhenium-188 offers cost-effectiveness, on-site availability, short half-life, energetic beta particle, emission of gamma photons for imaging, easy preparation, easy clinical administration and apparent lack of radiation leakage from the treated tumor. Direct intratumoral injection of 188Re microspheres is extremely attractive as a clinical therapeutic alternative in hepatoma patients.

Abstract
Hereditary spastic paraplegia (HSP) is a degenerative disorder of the central nervous system, characterized by progressive weakness and spasticity of the lower extremities. The first symptom is usually leg stiffness, unstable gait with difficulty in walking. According to the clinical features, hereditary spastic paraplegia can be divided into pure type and complicated type. The mode of hereditary spastic paraplegia can be autosomal dominant, autosomal recessive or X-linked. There have been many loci on chromosomes identified in recent years. We present two Chinese siblings with unstable gait, a 5-year-3-month-old brother and his 3-year-1-month-old sister, who belong to the pure type hereditary spastic paraplegia. Both of them had motor deficit on follow up.

Primary intracranial germ-cell tumor in children. ZHONGHUA YI XUE ZA ZHI = CHINESE MEDICAL JOURNAL; FREE CHINA ED 1997; 60:259-64.

Abstract
BACKGROUND Primary intracranial germ-cell tumors (GCTs) account for about 11.1% of all primary brain tumors of children in Taiwan. Because these tumors commonly involve the hypothalamus-pituitary gland regions and their biochemical secreting character, patients frequently display neuroendocrinological symptoms and signs. Endocrinopathy, if present, often occurs prior to other neurological or radiological manifestations. This article reviews experience here, with present results comparing them with previous reports. METHODS Twelve children who were diagnosed with primary intracranial germ-cell tumors between 1983 to 1995 were studied retrospectively. Their clinical presentations, laboratory results and treatment modalities as well as the current status were collected for presentation here. RESULTS There were seven boys and five girls. The age distribution was from 5 to 15 years old. The most common symptom was increased intracranial pressure (9/12), followed by diabetes insipidus (8/12), vision deficit (8/12) and sexual precocity in 3 boys. In 11 patients the tumors arose from the suprasellar or pineal regions. In two patients the tumors arose synchronously in the suprasellar and pineal regions. Pure germinoma was found in six patients. Only one had an elevated tumor marker. These six patients all received radiation with or without operation therapy, and all are still alive. Six patients, each with a non-germinomatous malignant germ-cell tumor, had a poorer prognosis. Although they received aggressive treatment, including operation, radiation and chemotherapy, three patients died, with a mean survival period of 3.3 years. CONCLUSIONS In cases of diabetes insipidus in children or sexual precocity in boys, a thorough investigation for intracranial germ-cell tumors is recommended. The treatment and outcome are different for germinomas and non-germinomatous malignant germ-cell tumors. A thorough pathological diagnosis is recommended for planning of treatment protocol in order to improve prognosis.

Abstract
We present a Chinese female infant with an intermittent form of MSUD whose early development was relatively well. A total of three episodes of stupor and metabolic acidosis developed with a concurrent illness after the age of 13 months. The initial analyses of plasma amino acid and urinary organic acid were normal. Initially, an abnormal oral glucose lactate stimulation test and high signal in the bilateral globus pallidus over T2-weighted brain MRI led us to suspect a mitochondrial disorder. The final diagnosis was made after the patient died at 31 months of age.

Abstract
Intoxication after ingestion of toad is rare, but it results in severe morbidity and high mortality. Recently, we encountered 2 children, one a 15-month-old boy and one a 20-month-old girl, who were fed cooked toad (Bufo melanostictus) soup. The boy expired of ventricular fibrillation. The girl presented with varying degrees of A-V block with congestive heart failure which, however, was completely resolved after intensive treatment. In our experience, early identification and intervention are necessary to decrease absorption of toxins; to correct hyperkalemia. Dysrhythmia should be treated with atropine, antiarrhythmic agents, and a temporary pacemaker, in order to avoid lethal results.

Abstract
A 2 5/12-year-old Chinese boy was investigated for refractory seizures and psychomotor regression. His birth history was unremarkable. Generalized seizures occurred at 2 weeks of age with hypocalcemia. They recurred at 7 months of age and have become aggravated since. During hospitalization, in addition to hypocalcemia and hypomagnesemia, he was found to have hypoparathyroidism, cardiomyopathy, and brain atrophy. Excessive renal loss of magnesium, general intestinal malabsorption, or inadequate dietary intake of magnesium were excluded. He was successfully treated with oral supplements of 19-25 mmole/day of magnesium. Over a few months, he made a dramatic progress in development. His hypoparathyroidism and cardiomyopathy gradually resolved. However, intermittent seizures and psychomotor retardation persisted up to his present age of 6 3/12 years. At 4 months of age his younger sister also developed seizures and was found to have isolated hypomagnesemia. This was corrected by oral magnesium and followed by resolution of the seizure. She has developed normally up to her present age of 1 10/12 years. Both patients are currently maintained on oral magnesium oxide.

Central core disease associated with scoliosis: report of one case. ZHONGHUA MINGUO XIAO ER KE YI XUE HUI ZA ZHI [JOURNAL]. ZHONGHUA MINGUO XIAO ER KE YI XUE HUI 1997; 38:297-9.

Abstract
A 13 year-old girl with scoliosis and central core disease is reported. She was noted to have mild psychomotor developmental delay since early infancy. Scoliosis with minimal muscle weakness was noted at about five years old. The neurological examination disclosed absent knee jerk. The spine MRI showed no significant finding. The serum CK revealed 518 U/L. The muscle biopsy obtained from the quadriceps femoris muscle showed Type 1 fiber atrophy and predominance, as is commonly seen in congenital myopathies. Under nicotinamide adenine dinucleotide dehydrogenase (NADH) and succinate dehydrogenase (SDH) stains, core structures were identified and the diagnosis of central core disease (CCD) was made. Since kyphoscoliosis usually becomes prominent as muscle weakness progresses to loss of ambulation in other myopathies, the disproportionate spinal involvement in central core disease appears to be a striking feature. We suggest that all patients with idiopathic scoliosis deserve a thorough neurological evaluation if congenital myopathies are suspected. Muscle biopsy should also be recommended for a confirmatory diagnosis even if only minimal muscle weakness present. Besides, early detection of CCD helps us to identify the population who are at a higher risk for malignant hyperthermia.

Clinical analysis of 22 infants with afebrile cluster seizures. ZHONGHUA MINGUO XIAO ER KE YI XUE HUI ZA ZHI [JOURNAL]. ZHONGHUA MINGUO XIAO ER KE YI XUE HUI 1997; 38:203-7.

Abstract
The inclusion criteria for afebrile cluster seizures in infancy are defined as follows: (1) frequency of afebrile seizures at least 2 episodes within 72 hours; (2) seizure onset between 2 months and 3 years of age; (3) excluding febrile convulsion, central nervous system infections, status epilepticus, well-known epileptic syndromes in infancy (e.g. early myoclonic encephalopathy, early infantile epileptic encephalopathy, benign myoclonic epilepsy, infantile spasms. Lennox-Gastaut syndrome), electrolyte imbalance, watery diarrhea, head injury and intoxication. From 1986 to 1996, retrospectively and prospectively 22 patients were collected who fulfilled the above criteria. Based on whether or not a strong family history was present and a history of mild diarrhea was associated with seizure onset, they were divided into three groups: Group I, benign infantile familial convulsions (4 patients); Group II, cluster seizures with mild diarrhea in infancy (5 patients); Group III, cluster seizures without diarrhea in infancy (13 patients). Before seizure onset and during follow-up, all of the patients had normal development. The seizure pattern in all was generalized, most tonic type with duration of seizure less than five minutes in the majority. Recurrence rate was 100% in Group I and no recurrence in Group II. In 16 patients who were seizure-free over 12 months, the duration of persistence varied from 1 day to 8 months, and was shortest in Group II (range, 1 to 3 days). It was concluded that the vast majority of afebrile cluster seizures in infancy are benign in nature. Whether anticonvulsant therapy is justified must be individualized.
