An 8-year-old female, German Shepherd dog was presented with history of dyspnea and seizure. One Year Previously a lumpectomy had been performed for surgical resection of mammary mass. In serum chemistry, severe hypoglycemia and elevation of aspartate aminitransferase and creatine kinase were shown. In thoracic radiography, there were variable sized nodules in the overall lung field. On computed tomography examination, the mass was shown in left longissimus lumborum muscle. Histopathological examination revealed adenocarcinoma derived from the mammary gland. Muscular metastasis of mammary gland tumor is uncommon. This is a rare observation and could easily be overlooked or misinterpreted.

It is well-known that the prevalence of attention deficit hyperactivity disorder (ADHD) is higher in epileptic children than in the general pediatric population. The aim of this study was to compare the accompaniment of ADHD in epileptic children with well-controlled seizures and no significant intellectual disability with that in healthy controls. We included epileptic children between the ages of 6 and 12 yr visiting our clinic for six consecutive months and controls without significant medical or psychiatric illnesses. We excluded patients with intellectual disability or persistent seizures during the recent three months. The diagnosis of ADHD was based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). After exclusion of 84 patients, we enrolled 102 (54.8%) children (mean age, 9.4 +/- 2.0 yr). Seven (7 of 102, 6.9%) were diagnosed with ADHD. As compared to control group (4 of 110, 3.6%), there was no difference in ADHD accompaniment (P = 0.29). No difference was observed in ADHD accompaniment according to seizure type and epilepsy syndrome. In conclusion, the accompaniment of ADHD in epileptic children with well-controlled seizures and no intellectual disability may not differ from that of the general pediatric population.

PURPOSE: The purpose of this study is to examine the usefulness of the head-up tilt test for diagnosis of unexplained syncope in children. METHODS: Head-up tilt test results and clinical features of 41 children with unexplained syncope, presyncope, dizziness and seizure were studied from January, 1997 through January, 2001 at Asan Medical Center. Medical records of children were reviewed retrospectively. The children were evaluated with an 80 degrees head-up tilt test for 15 minutes with or without intravenous infusion of isoproterenol(0.05-0.1 ng/kg/min). RESULTS: 41 children made up the study population, of whom 23(56%) had a positive head-up tilt test and 21(60%) of 35 patients with a history of syncope or presyncope had a positive head-up tilt test. Isoproterenol infusion provoked the more positive head-up tilt test. The patients with positive test results showed three patterns of response to tilting. 16 patients had a predominantly vasodepressor response; three patients had a cardioinhibitory response; and four patients had a mixed response. The patients had an average of five studies performed per patient, including chest radiograph, electrocardiogram, 24 hour Holter monitoring, treadmil test, head computed tomographic scan or magnetic resonance imaging, and echocardiography. The head-up tilt test was most effective for evaluation of unexplained syncope in children. CONCLUSION: Head-up tilt testing performed early in the evaluation will increase the probability of a diagnosis, and will often prevent the need for further extensive, expensive, anxiety-producing tests in children. More controlled studies and a standardization of degree and duration of tilting are necessary to validate the head-up tilt test as a useful diagnostic tool in children with unexplained syncope.

Hand, foot, and mouth disease (HFMD) is an acute, mostly self-limiting infection. Patients usually recover without any sequelae. However, a few cases are life threatening, especially those caused by enterovirus 71 (EV71). A 12-month-old boy was admitted to a primary hospital with high fever and vesicular lesions of the mouth, hands, and feet. After 3 days, he experienced 3 seizure episodes and was referred to our hospital. On admission, he was conscious and his chest radiograph was normal. However, 6 hours later, he suddenly lost consciousness and had developed a massive pulmonary hemorrhage that continued until his death. He experienced several more intermittent seizures, and diffuse infiltration of both lung fields was observed on chest radiography. Intravenous immunoglobulin, dexamethasone, cefotaxime, leukocyte-depleted red blood cells, fresh frozen plasma, inotropics, vitamin K, and endotracheal epinephrine were administered. The patient died 9 hours after intubation, within 3 days from fever onset. EV71 subgenotype C4a was isolated retrospectively from serum and nasopharyngeal swab by real-time reverse transcription-polymerase chain reaction. Here, we report a fatal case of EV71-associated HFMD with sudden-onset massive pulmonary hemorrhage and suspected encephalitis.

We report a case of reversible encephalopathy syndrome in a 16-year-old girl with acute myelogenous leukemia (AML), who is undergoing during consolidation chemotherapy composed of BH-AC (N4-behenoyl-1-beta-D-arabinofuranosyl cytosine) and idarubicin. On the 6th day of chemotherapy, she was in a drowsy state following generalized tonic clonic seizure lasting 20 minutes. MR images revealed extensive cortical and subcortical white matter brain edema. Alertness returned over the 24 hr following by the discontinuation of BH-AC and intravenous administration of diphenylhydantoin, although she complained of intermittent headaches and visual disturbance. She gradually recovered from these symptoms during subsequent 7 days. Previously noted abnormal signal intensities have nearly disappreared on follow-up MRI obtained on the 22nd day after the first seizure. She was discharged without any neurologic sequela. This case suggests that BH-AC, a derivative of cytosine arabinoside (1-beta-D-arabinofuranosylcytosine) could be a cause of reversible encephalopathy syndrome.

Umbilical cord blood (UCB)-derived mesenchymal stem cells (MSCs) have been introduced as a possible therapy in acute lung injury and acute respiratory distress syndrome (ARDS). This case history is reported of a 59-yr-old man who was treated with MSCs in the course of ARDS and subsequent pulmonary fibrosis. He received a long period of mechanical ventilation and weaning proved difficult. On hospital day 114, he underwent the intratracheal administration of UCB-derived MSCs at a dose of 1 x 10(6)/kg. After cell infusion, an immediate improvement was shown in his mental status, his lung compliance (from 22.7 mL/cmH2O to 27.9 mL/cmH2O), PaO2/FiO2 ratio (from 191 mmHg to 334 mmHg) and his chest radiography over the course of three days. Even though he finally died of repeated pulmonary infection, our current findings suggest the possibility of using MSCs therapy in an ARDS patient. It is the first clinical case of UCB-derived MSCs therapy ever reported.

A 42-year-old Chinese man presented with left-sided chest pain and splenomegaly. Full blood count revealed erythrocytosis, while plain radiograph and computed tomography of the abdomen and pelvis revealed hepatosplenomegaly with splenic infarction. Further workup confirmed the diagnosis of polycythaemia vera. Clinical and imaging features of polycythaemia vera, as well as the potential pitfalls in image interpretation, are discussed in this article.

OBJECTIVECerebral infarction (CI) is one of severe diseases of central nervous system in neonates, and some infants with CI could have poor prognosis in the long term. This study aimed to analyze the clinical data and prognosis of all neonatal cases with cerebral infarction in recent years and to help future clinical work.

METHODTotally 58 neonatal cases with CI admitted to NICU of the hospital from January 1999 to December 2010 were included in this study. We analyzed all clinical data and prognosis by retrospective analysis.

RESULTSFifty-two term babies and six preterm babies were included. There were altogether 51 cases with asphyxia and 7 with hemorrhagic cerebral infarction. Perinatal hypoxia-ischemia was the most common high-risk factor and it accounted for 46.6%. Seizure was the most frequent initial symptom and the most common clinical manifestation (accounted for 77.6%), and it was followed by intermittent cyanosis, apnea and lethargy. Cerebral CT scan and magnetic resonance imaging were major methods to help to make the diagnosis and they also had close relation with prognosis. Diffusion weighted imaging was very helpful to diagnose infarction in early stage. Left middle cerebral artery was the most common artery to be involved. Supportive therapy and symptomatic treatment were the main methods in the acute stage of neonatal cerebral infarction. Those babies with poor prognosis mostly had large infarction involving cerebral hemisphere, thalamus and basal ganglia.

CONCLUSIONSNeonatal cerebral infarction was a severe brain injury affecting long tern nervous system prognosis. Perinatal hypoxia was the most common high-risk factor and seizure was the most frequent initial symptom. Diffusion weighted imaging was valuable to diagnose infarction in early stage. Most of infants with poor prognosis had large infarction involving hemisphere, thalamus and basal ganglia. Early diagnosis with brain imaging would be helpful for rehabilitation therapy and improving prognosis.

OBJECTIVETo study the clinical and laboratory features and diagnosis of the patient with anti-N-methyl-D-aspartate receptor(NMDAR)encephalitis in children.

METHODThe data of clinical feature, laboratory findings, and radiological manifestation were reviewed and analyzed.

RESULTOf the 7 patients, 4 were female and 3 were male. The age of onset was from 6.6 to 15.5 years (average 9.5 years). The onset of 4 cases started with convulsion. Six cases had seizures which was difficult to control by antiepileptic drugs. All patients had psychiatric symptoms and speech disorder. Six cases had different levels of decreased consciousness and dyskinesias. 6 cases had autonomic nerve instability, and 7 cases developed sleep disorders. The results of MRI examination were normal in all patients. The EEG of most patients showed focal or diffuse slow waves. Six cases had oligoclonal bands. All cases were confirmed to have the disease by detection of anti-NMDA receptor antibodies. No tumor was detected in any of the patients. All patients received immunotherapy.

CONCLUSIONAnti-NMDAR encephalitis is a severe but treatable disorder that frequently affects children and adolescents. Pediatric patients had clinical manifestations similar to those of adult patients. But children have a lower incidence of tumors and hypoventilation also occurs less frequently in children. Most of children had a good prognosis.
