Congenital megacystis with bilateral hydroureteronephrosis is most commonly associated with posterior urethral valves, prune-belly syndrome, vesicoureteral reflux, or nonrefluxing, nonobstructive megaureters. Among the other cause of congenital megacystis, megacystis-microcolon-intestinal hypoperistalsis syndrome(MMIHS), which is characterized by megacystis, microcolon and hypoperistalsis of the intestines with resultant abdominal distension, is a rare cause of functional obstruction of urinary tracts in childhood. It was... |
Neuroblastoma is the most common intraabdominal malignant tumor of childhood, with 40% arising from the adrenal gland. Bilateral adrenal involvement from synchronous development or metastatic spread of tumor is rarely seen in children with neuroblastoma. The patient was born with a spontaneous vaginal delivery. Birth weight was 3,200 g. Fetal ultrasonography showed a left adrenal cystic mass. At two weeks... |
Syncope in children and adolescents have a common occurrence according for up to 15% before adulthood. Micturition syncope, a kind of situational syncope, can be considered a form of reflex syncope. It can typically occur in healthy young men after rising from bed in the early morning who experience sudden loss of consciousness during or immediately after urination. The mechanism... |
Labial adhesions are postnatal fusion of the labia minora in the midline of varying degrees. They are postulated to be the result of low estrogen levels in the prepubertal child and possibly of a chronic inflammatory process. Topical treatment with conjugated estrogens has been the mainstay of therapy. We experienced one case of labial adhesion in an infant who was... |
The advance of the immunobiology clarifies the nature of non-Hodgkin's lymphoma(NHL). In addition the proceed in the immunophenotyping renders the classification of NHL. According to the Revised European American Lymphoma(REAL) classification, classified by the etiologic factors, molecular biological characteristics, immunophenotype, cytogenetics and histologic feature, nasal T/NK-cell lymphoma(=angiocentric lymphoma) belongs to the category of peripheral T-cell and natural killer cell lymphoma.... |
Rickets is a nutritional disorder which is caused either by deficiency of vitamin D or by a defective activation of vitamin D. In these days, even though the incidence of rickets has decreased through adequate nutritional support, we sometimes experience rickets in babies receiving a prolonged special diet as therapy for chronic diarrhea, or those subject to a in receiving... |
Human parvovirus(HPV) B19 infection causes erythema infectiosum in children, sometimes red cell aplastic crisis with hemolytic anemia and chronic bone marrow failure in immunocompromised hosts. HPV B19 is directly cytotoxic for erythroid progenitor cells and inhibits erythropoiesis. Infrequently, HPV B19 inhibits hematopoiesis of three cell lineages and causes transient pancytopenia in patients with hemolytic disorders. We report three patients with... |
KID syndrome was named after the initials of the major three symptoms of the disease; keratitis, ichthyosis, and deafness. The syndrome was first introduced by Dr. Burns in 1915 who described one of his patients with those symptoms. In 1981, Dr. Skinner and his colleagues reported 17 patients who had keratitis, ichthyosis, and deafness. They also called the disease KID... |
The ketogenic diet is a high-fat, low-protein, low-carbohydrate diet developed in the 1920s for the treatment of difficult-to-control seizures. Despite advances in both the pharmacotherapy and the surgery of epilepsy, many children continue to have difficult-to-control seizures. In this situation, a ketogenic diet should be considered as an alternative therapy. However, less attention has been paid to associated adverse events... |
Retinoic acid has been used successfully as a differentiating agent in acute promyelocytic leukemia and neuroblastoma. However, some adverse effects have been recognized, such as headaches, dry skin and retinoic acid syndrome, a life threatening acute cardiorespiratory disorder. Acute pancreatitis with hyperlipidemia has rarely been reported. We experienced a case of acute pancreatitis with hyperlipidemia in a neuroblastoma patient after... |
We evaluated the clinical and laboratory characteristics of five children with Kawasaki disease who had showed arthritis after responding to intravenous immunoglobulin(IVIG) treatment. Age distribution was between 13 months and six years of age(mean 3.2?.6 years). There were two males and three females. Arthritis occurred when acute symptoms were subsiding, with the average onset on day 5.8?.8 after final IVIG... |
Maternal varicella resulting in viremia may transmit the virus to the fetus by either transplacental spread, or by ascending infection from lesion in the birth canal. The characteristic symptoms consist of skin lesions in dermatomal distribution, eye diseases, neurological defects, and limb hypoplasia. Varicella of the newborn is a life-threatening illness that may occur when a newborn is delivered either... |
Craniofrontonasal dysplasia(CFND), a rare congenital syndrome, is characterized by varying degrees of frontonasal dysplasia, craniosynostosis, and variable extracranial abnormalities. It was first reported by Cohen in 1979. The inheritance pattern is not straightforward. Although all modes of Mendelian inheritance have been suggested, the most plausible explanation is that this is an X-linked condition with the unusual situation of complete expression... |
Henoch-Shonlein purpura(HSP) is a systemic small-vessel vasculitis that primarily affects the skin, gastrointestinal tract, joints, and kidneys. The nervous system may be involved, less commonly than other organs. When the central nervous system(CNS) was involved, headache, changes in mental status, seizures, and focal neurologic deficits have been reported. Hypertension, uremic encephalopathy, metabolic abnomalities, electrolyte abnormalities, or cerebral vasculitis were suggested... |
Sandifer syndrome is a rare manifestation of gastroesophageal reflux in children, occurring in association with abnormal movement of the head and neck and recurrent episodes of seizure after feeding. This syndrome may be misdiagnosed as infantile seizure and musculoskeletal disorder and may be associated with failure to thrive, anemia, aspiration pneumonia, and esophagitis. In this paper, Sandifer syndrome in a... |
In pseudohypoparathyroidism as reported by Albright in 1942, the parathyroid gland can normally synthesize and secrete parathyroid hormone(PTH). Pseudohypoparathyroidism has a similar biochemical finding with hypoparathyroidisms like hypocalcemia and hyperphosphatemia due to target tissue resistance to PTH. Administered PTH does not raise the serum levels of calcium and urinary phosphate. PTH activates G-protein in peripheral tissue and adenylate cyclase through... |
Hemophagocytic lymphohistiocytosis is a reactive disorder characterized by a generalized non-malignant histiocytic proliferation with prominent hemophagocytosis by stimulated histiocytes in the bone marrow and reticuloendothelial systems resulting in pancytopenia and liver dysfunction. Several diseases including infection, malignancy and autoimmune disease are known to be causative disorders. This case demonstrated histiocytic hemophagocytosis in the bone marrow, resulting in pancytopenia during treatment... |
Influenza-associated encephalopathy is regarded as one of the major neurologic disease entities along with those of Reye syndrome, acute necrotizing encephalopathy, and myelitis which are known to be related to influenza virus, mostly type A. And it is being actively researched in Japan as it has caused a tremendous increase in the number of deaths from 1997 to 2002, but... |
Neonatal herpes simplex virus(HSV) infections result in significant morbidity and mortality. Although acyclovir treatment has improved survival, severe neurological sequelae can occur in the majority of survivors. HSV infections limited to the skin, eyes and mouth(SEM) can cause neurologic impairment. A direct correlation exists between the development of neurologic deficits and the frequency of cutaneous HSV recurrences. National Institutes of... |
Canavan disease, also known as van Bogaert-Bertrand disease, is a rare autosomal recessive disorder characterized by early an onset and a progressive spongyform degeneration of the brain, associated with an edema of the central nerve system, intramyelinic swelling and neurologic symptoms. This disorder is most prevalent in people of Ashkenazi Jewish descent but has been observed in other ethnic groups.... |
Hydrocarbon pneumonitis is an inflammatory change in the lungs caused by ingestion or inhalation of household products that contain hydrocarbons. We experienced a rare case of hydrocarbon pneumonitis with a pulmonary hemorrhage in a 3-year-old girl after ingestion of paint thinner which has a high mortality. She was admitted due to dyspnea, vomiting, hemoptysis, and needed to support mechanical ventilation.... |
Intestinal lymphangiectasia, one of the protein-losing gastroenteropathies, is an uncommon disease characterized by dilated intestinal lymphatics, enteric protein loss, edema, hypoalbuminemia, and lympocytopenia. Small bowel biopsy and CT have been used to confirm the diagnosis of intestinal lymphangiectasia. Small bowel biopsy shows collections of abnormal dilated lacteals in submucosa with distortion of villi and CT findings have been described as... |
Herpes simplex virus infection of the hand in children occurs after auto-inoculation from herpetic gingivostomatitis or herpes labialis. Herpetic whitlow should be suspected based on clinical signs. Diagnosis can be made by PCR or virus culture. Many misdiagnosed cases suggests that this disease is not sufficiently known. Surgical interventions may be harmful and should be avoided. We report a case... |
Cardiac rhabdomyomas are relatively uncommon and associated with tuberous sclerosis in 40-50% cases. We report a 10-month-old infant with tuberous sclerosis who presented with ventricular arrythmias and status epilepticus. There were hypopigmented macules on the body, periventricular calcifications, renal cyst and cardiac rabdomyomas just below the aortic valve. The patient required resection of left ventricular subaortic masses due to sustained... |
Klippel-Trenaunay syndrome is a rare mesodermal phakomatosis characterized by cutaneous haemangiomata(usually unilateral and involving an extremity), venous varicosities and osseous and soft tissue hypertrophy, of the affected limb. Sturge-Weber syndrome, also a mesodermal pharkomatosis, is characterized by a port-wine nevus, which is present from birth and covers the face and cranium in the territory of the first division of the... |
Holoprosencephaly of unknown definite causes, has been associated with several chromosome abnormalities involving the autosomes and the sex chromosomes. The most commonly reported associations include dup(3p), del(7q), deletions of chromosome 13, trisomy 13, trisomy 18, and triploidy. In previously reported cases in Korea, none were associated with chromosome 21 anomalies. In conclusion, we reported the first case of holoprosencephaly(semilobar type)... |
ARCI syndrome consists of arthrogryposis, renal tubular acidosis, cholestatic jaundice and icthyosis. We experienced an ARCI syndrome case with corpus callosum hypoplasia and atrial septal defect. This case had oral feeding difficulty, multiple joint contracture, renal tubular acidosis and neurogenic muscular atrophy at neonatal period. At two months of age, icthyosis and cholestatic jaundice were diagnosed. The case was hospitalized... |
Malaria is known to have been eradicated for a few decades through the persistent efforts of the national health program in South Korea. However, malaria caused by Plasmodium vivax has started to reappear incidiously among military personnel near to the De-militarized Zone since 1993. From that time on the number of malarial cases have increased abruptly year by year. However,... |
Intussusception is a common cause of lower intestinal bleeding from five to 11 months of age. Typical symptoms are paroxysmal colicky pain, irritability, vomiting, abdominal mass and currant jelly stool, but hematemesis is rare. Though the most common type of intussusception is ileocecal type, it is rarely accompanied with hematemesis. Up until the present, hematemesis has been observed rarely but... |
The isoimmune hemolytic disease of newborn due to the incompatibility of minor blood groups is characterized by progressive neonatal hyperbilirubinemia and anemia caused by the IgG antibody transmitted from the mother to the fetus. Recently we had a case of hemolytic disease in a newborn due to anti-Jkb. There were no ABO and Rh(D) incompatibilities between mother and baby. The... |
