1.The significance of corpus callosal size in the estimation of neurologically abnormal infants.
Korean Journal of Pediatrics 2008;51(11):1205-1210
PURPOSE: The development of the corpus callosum occupies the entire period of cerebral formation. The myelination pattern on magnetic resonance imaging (MRI) is very useful to evaluate neurologic development and to predict neurologic outcome in high risk infants. The thickness of the corpus callosum is believed to depend on the myelination process. It is possible to calculate the length and thickness of the corpus callosum on MRI. Thus, we can quantitatively evaluate the development of the corpus callosum. We investigated the clinical significance of measuring various portions of the corpus callosum in neonate with neurologic disorders such as hypoxic brain damage and seizure disorder. METHODS: Forty-two neonates were evaluated by brain MRI. We measured the size of the genu, body, transitional zone, splenium, and length of the corpus callosum. Each measurement was divided by the total length of the corpus callosum to obtain its corrected size. The ratio of corpus callosal length and the anteroposterior diameter of the brain was also measured. RESULTS: There was no statistical significance in the sample size of each part of the corpus callosum. However, the corrected size or the ratio of body of the corpus callosum correlated with periventricular leukomalacia and hypoxic ischemic encephalopathy. CONCLUSION: There was no statistical significance in the sample size of each part of the corpus callosum. However, the corrected size or the ratio of body of the corpus callosum correlated with periventricular leukomalacia and hypoxic ischemic encephalopathy.

Diphyllobothrium latum infection in humans is not common in Republic of Korea. We report a case of fish tapeworm infection in a 10-year-old boy after ingestion of raw perch about 8 months ago. The patient complained of recurrent abdominal pain and watery diarrhea. A tapeworm, 85 cm in length, without scolex and neck, was spontaneously discharged in the feces of the patient. The patient was treated with 15-mg/kg single dose praziquantel, and follow-up stool examination was negative after one month. There was no evidence of relapse during the next six months.

Transient hyperammonemia in a newborn is an overwhelming disease manifested by hyperammonemic coma. The majority of affected newborns are premature and have mild respiratory syndrome. The diagnosis may be difficult to determine. This metabolic disorder is primarily characterized by severe hyperammonemia in the postnatal period, coma, absence of abnormal organic aciduria and normal activity of the enzymes of the urea cycle. Hyperammonemic coma may develop within 2-3 days of life, although its etiology is unknown. Laboratory studies reveal marked hyperammonemia (>4,000 micromol/L). The degree of neurologic impairment and developmental delay in this disorder depends on the duration of hyperammonemic coma. Moreover, the infant may succumb to the disease if treatment is not started immediately and continued vigorously. Hyperammonemic coma as a medical emergency requires dialysis therapy. Here, we report a case of severe transient hyperammonemia in a preterm infant (35 week of gestation) presented with respiratory distress, seizure, and deep coma within 48 hours and required ventilatory assistance and marked elevated plasma ammonia levels. He survived with aggressive therapy including peritoneal dialysis, and was followed 2 years later without sequelae.

Neurenteric cyst is a rare, congenital, and benign cystic lesion of the central nervous system, which is generally thought to result from failure of separation of the neuro-ectodermal and neuro-endodermal elements during week 3 of embryogenesis. Neurenteric cysts in the intracranial area are very rare lesions that typically occur in the spinal canal or even more seldom in the posterior cranial fossa. A girl presented to the outpatient clinic with complaints of moderate to severe episodes of headache with associated vomiting for 2 weeks. There was a positive sign of severe neck stiffness. Her brain MRI showed a neurenteric cyst located within the anterior intradural space of the foramen magnum. We report our experience with an intracranial neurenteric cyst located in the anterior brain stem area.

Background:
Fever is a common cause of pediatric consultation in the emergency department. However, identifying the source of infection in many febrile infants is challenging because of insufficient presentation of signs and symptoms. Meningitis is a critical cause of fever in infants, and its diagnosis is confirmed invasively by lumbar puncture. This study aimed to evaluate potential laboratory markers for meningitis in febrile infants.
Methods:
We retrospectively analyzed infants aged <3 months who visited the emergency department of our hospital between May 2012 and May 2017 because of fever of unknown etiology. Clinical information and laboratory data were evaluated. Receiver operating characteristic (ROC) curves were constructed.
Results:
In total, 145 febrile infants aged <3 months who underwent lumbar punctures were evaluated retrospectively. The mean C-reactive protein (CRP) level was significantly higher in the meningitis group than in the non-meningitis group, whereas the mean white blood cell count or absolute neutrophil count (ANC) did not significantly differ between groups. The area under the ROC curve (AUC) for CRP was 0.779 (95% confidence interval [CI], 0.701–0.858). The AUC for the leukocyte count was 0.455 (95% CI, 0.360–0.550) and that for ANC was 0.453 (95% CI, 0.359–0.547). The CRP cut-off value of 10 mg/L was optimal for identifying possible meningitis.
Conclusion
CRP has an intrinsic predictive value for meningitis in febrile infants aged <3 months. Despite its invasiveness, a lumbar puncture may be recommended to diagnose meningitis in young, febrile infants with a CRP level >10 mg/L.

PURPOSE: To identify trends in bacterial organisms and antimicrobial susceptibilities for transmission by outborn neonates, it is important to perform surveillance cultures. The aim of this study was to investigate major organisms and any other clinical factors through surveillance cultures of out-born neonates who transferred to neonatal intensive care units (NICU). METHODS: This study is a retrospective collected data among 189 out-born neonates admitted to NICU from Mar. 2012, to Feb. 2014. Surveillance cultures were obtained routinely from both nasal and axillary region and inoculated CHROM agar(TM) MRSA immediately. Bacterial culture identification and antibiotic susceptibility were carried out using Vitek II ID-GPI card. RESULTS: The most prevalent organisms isolated from the nasal surveillance cultures were methicillin-resistant Staphylococcus aureus (MRSA) and coagulase negative Staphylococcus (CoNS) (each 17 cases vs. 11 cases); both vancomycin and rifampin were susceptible. Only 1 case of S. epidermidis has same result in blood and surveillance culture. Demographic, clinical and healthcare related parameters according to surveillance culture results were compared, but no obvious association was apparent on above parameters. Nevertheless, positive surveillance culture group showed lower birth weight and longer duration until transferred to NICU. CONCLUSION: In our surveillance culture study showed that MRSA and CoNS were the most common organisms in out-born neonates; both were penicillin- and oxacillin-resistant on antibiotic susceptibility testing. Although there is no statistical meaning, positive surveillance culture group showed relatively lower birth weight and longer duration from birth to NICU arrival. These findings were contributed to obtain a reliable policy of the transmission in NICU.

PURPOSE: We evaluated the effectiveness of treatment and cardiac complications of replacing a high dose of aspirin with a high dose of ibuprofen for children in acute phase of Kawasaki disease. We also analyzed the possibility of replacing a high dose of aspirin with a high dose of ibuprofen to prevent complications such as Reye's syndrome caused by aspirin. METHODS: One hundred eight children with Kawasaki disease were admitted in the pediatrics department from January 1, 2004 to December 31, 2008. Echocardiography and laboratory tests were performed during diagnosis, and the children were followed-up at 6-8 weeks after the diagnosis. We retrospectively analyzed their characteristics and clinical results. RESULTS: The children were assigned to receive either a high dose of aspirin with intravenous immunoglobulin (IVIG) (aspirin group) or a high dose of ibuprofen with IVIG (ibuprofen group). A total of 55 and 53 children were included in the aspirin and ibuprofen groups, respectively. The mean defervescence period was 6.5+/-2.1 days in the aspirin group, and 6.9+/-1.9 days in the ibuprofen group (P=0.309). The number of failed treatments, during and after treatment, was 8 in the aspirin group and 10 in the ibuprofen group (P=0.547). There were 11 initial cardiac complications in the aspirin group, and 14 in the ibuprofen group, but children who showed improvement at follow-up was 7 and 13 in the aspirin and ibuprofen groups, respectively (P=0.133). Laboratory findings were also improved in both groups. CONCLUSION: We can be considered whether we will replace high dose of aspirin by high dose of ibuprofen in acute phase of Kawasaki disease. Therefore, we can prevent the severe complications of aspirin use, such as Reye's syndrome.

Duplication cysts are rare congenital malformations, that may be detected anywhere along the alimentary tract, and they may communicate with the intestinal tract. Cystic duplication of the cecum is especially rare. About 80% of these cases are detected in the first 2 years of life as a result of an acute intestinal obstruction, which manifests as vomiting, recurrent abdominal pain, recurrent gastrointestinal bleeding and constipation. We report a case of intestinal obstruction secondary to a duplication cyst of the cecum in a neonate. The patient underwent surgery and was diagnosed subsequently, and is presently healthy.

The perforation and subsequent panperitonitis as one of the complications of a Meckel diverticulum is a rare complication, especially in infants. Complication of Meckel diverticulum, preoperative and operative patient's mean age is about 5 years old. A 13-month-old male infant presented at our emergency room with currant jelly stool of about 24 hours duration. Intussusception or bacterial enteritis was initially suspected. Gastrointestinal ultrasonography showed no evidence of intussusception or appendicitis. On the 3rd hospital day, he suddenly showed high fever and irritability. Abdominal CT suggested intraperitoneal and retroperitoneal abscess with air collection due to possible bowel perforation. The final diagnosis of perforation of Meckel diverticulum was made by laparoscopy and biopsy. We report a very rare case with perforation of Meckel diverticulum in infant period.

Mesenteric cysts are rare intra-abdominal lesions occurring during childhood, which were first described in 1507. Cases of mesenteric cysts have been continuously reported, but these cases were very small in number. They are often asymptomatic and incidentally found while patients are undergoing work-up or receiving treatment for other conditions such as appendicitis, small-bowel obstruction, or diverticulitis; however, patients may still have lower abdominal pain and symptoms that are frequently associated with other abdominal conditions. The symptoms are variable and non-specific, including pain (82%), nausea and vomiting (45%), constipation (27%), and diarrhea (6%). An abdominal mass may be palpable in up to 61% of patients. We are to report the clinical course and literature of a child with mesenteric cysts who complained of acute abdominal pain, distension, and vomiting and were surgically treated after being diagnosed with mesenteric cysts based on radiological examination.
