Diffuse panbronchiolitis(DPB) is a chronic inflammatory airway disease predominantly affecting respiratory bronchioles, with distinct clinicopathological profiles. It was first described in 1966 by Yamanaka et al. The etiology of DPB is not yet clear, and the natural history of the disease is respiratory failure leading to cor pulmonale and ultimately death. But the long-term use of low-dose macrolide has proven... |
Neurofibromatosis type I is an autosomal dominant disorder with varied manifestations in bone, soft tissue, the nervous system and skin. This is characterized by cafe-au-lait spots, neurofibromas, Lisch nodules, optic glioma, bony displasia, and intertriginous freckling. One of the more serious aspect of the disease relates to the arterial involvement. Vascular changes in neurofibromatosis may occur in any arterial tree... |
Pyomysitis is a primary acute bacterial infection of large skeletal muscule, usually occuring in the absence of specific cause of infection. Pyomyositis has been reported mainly in tropical countries and was rare in temperate climates. but it has been recognized with increasing frequency. Toxic shock syndrome(TSS) is an acute mutisystemic disease characterized by high fever, hypotension, multisystem dysfunction and erythematous... |
Neonatal lupus(NL) is characterized by typical clinical features and the presence of maternal auto- antibodies. The principal serologic markers of NL are anti-Ro/SSA or anti-La/SSB maternal auto- antibodies, which are transferred across the placenta and can be detected for the first few months of the affected child. The major clinical manifestations are cardiac disease, notably congenital heart block, and cutaneous... |
Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis that can affect multiple organs predominantly the skin, joints, gastrointestinal tract and kidney. Although the specific pathogenesis of HSP is not known, there are several hypotheses. Although the importance of the complement activation in glomerular injury in HSP has been suggested, the complement levels and the blood pressure in... |
Tay-Sachs disease is an autosomal recessive, neurodegenerative disorder that results from excessive storage of the cell membrane glycolipid, and GM2 ganglioside within the lysosomes of cells. This disease is caused by deficiency of the isoenzyme β-hexosaminidase A, produced in the endoplasmic reticulum. Patients with Tay-Sachs disease are characterized by normal motor development in the first few months of life, followed... |
Aplastic anemia following acute hepatitis or acute hepatic failure is an uncommon disease and has a poor prognosis. We experienced a case of aplastic anemia following acute hepatic failure in a 10- year-old girl. She was admitted because of jaundice and lethargy for 8 days. Laboratory findings revealed marked elevated serum transaminases and bilirubin levels, prolonged prothrombin time and partial... |
Rothmund-Thomson syndrome(RTS), or poikiloderma congenita, is a rare, multisystem disorder. It is inherited genetically as an autosomal recessive trait, occurring predominantly in females(1.4 : 1). The RTS is comprised of poikiloderma, short stature, sparse hair, juvenile cataracts, skeletal defects, dystrophic teeth and nails, photosensitivity, and hypogonadism. We report a case of RTS who died of bleeding from esophageal varices, pulmonary... |
Hypodiploidy exists in 3-15% of patients with childhood acute lymphoblastic leukemia(ALL) and is associated with a poor prognosis. Monosomy 7 and monosomy 20 account for most karyotypic abnormalities in patients in whom whole chromosomes are lost and their incidences are rare. Parotid tumors in the pediatric age group are unusual and in 1996, there was a case of invasion of... |
Nonspecific ulcer of the small bowel is rare in children. Nonspecific ulcer of the colon or small bowel is clinically and pathologically recognized as a disease related to intestinal Behcet's disease. Differentiation of nonspecific ulcers from Behcet's ulcer by pathologic findings is often impossible and the clinical course is similar. A 13-year-old boy was admitted due to massive lower gastrointestinal... |
The most common pathogen of respiratory tract infection among school-age children and adolescents is Mycoplasma pneumoniae, which causes clinical manifestations of pneumonia, acute asthmatic attack, pharygitis, and tonsilitis. It can also cause extrapulmonary infections that involves skin, the nervous system, the digestive system, the cardiovascular system, and the hematopoietic system. It is reported that the central nervous system symptoms may... |
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm known by a variety of names including melanotic progonoma and retinal anlage tumor, and currently thought to be neural crest derivation. The vast majority develop within the first year of life. The behavior is generally benign, but recurrent and metastatic cases have been documented. It arises in the head and... |
A spinal cord injury without radiographic abnormality(SCIWORA) was defined by Pang and Wilberger in 1982 as the "objective signs of myelopathy as a result of trauma" in which no evidence of fracture, subluxation, or instability on plain radiographs, or computed tomography is demonstrable. Inherent elasticity of the vertebral column in infants and young children, among other age-related anatomical peculiarities, render... |
In 1938, Jarcho and Levin initially described shortening of the trunk, prominent occiput, broad forehead, multiple vertebral defects and ribs anomaly, short neck, increased anteroposterior chest diameter, lordosis, kyphoscoliosis. After that, Jarcho-Levin syndrome is an eponym that has been used to describe a variety of clinical phenotypes. We examined a girl who was suspected as suffering from Jarcho-Levin syndrome because... |
Fetal alcohol syndrome can be suspected in infants born to mothers with a prenatal history of alcohol abuse if the child exhibits characteristic facial features, together with intrauterine growth retardation, multiple neurological abnormalities, and multiorgan defects. If only a few of the above criteria are satisfied, the term fetal alcohol effects is used. We experienced a neonate who presented with... |
Weaver syndrome is a very rare overgrowth syndrome with accelerated skeletal maturation, unusual facies and clinodactyly. We experienced an extremely rare case of Weaver syndrome in Korea. The clinical manifestations were macrocephaly, unusal facies, simian crease, clinodactyly, decreased muscle tone, accelerated bone age and congenital heart diseases. We report this with a brief review of related literature. |
It has been estimated that chromosomal aberrations account for 2.3% to 3% of normal pregnancies, and of them, 85% are aborted. Therefore, the survival rate of neonates with chromosomal aberrations is very low. Among them, patients with partial deletion of the long arm of chromosome 13 are very rare. The natural history of deletion of the long arm is dependent... |
Dieulafoy's lesion is an unusual cause of massive gastrointestinal bleeding resulting from the erosion of an abnormally large submucosal artery. Recently, improvement of endoscopic techniques has made effective hemostasis possible in most cases of Dieulafoy's lesion. Aspirin, which is an anti-inflammatory agent, increases the incidence of major upper gastrointestinal complications. Gastroduodenal mucosal injury associated with aspirin therapy in patients in... |
VACTERL association is a disease with multiple congenital anomalies of the vertebrae, anus, cardia, tracheoesophageal(TE) fistula, renal and limb. This disease is derived from VATER anomaly, accompanied by cardiac and limb anomalies. We experienced a case of a 1-day-old boy with anal atresia, who represented multiple anomalies during hospital course. The multiple anomalies were hemivertebra, anal atresia, complex heart disease(coarctation... |
Congenital pulmonary vein stenosis(CPVS) with anatomically normal connection, a rare anomaly, usually leads to progressive pulmonary hypertension, cardiac failure in infancy, and death if untreated. Most are combined with other anomalies, particularly left to right shunt lesions. Very often, the detection of CPVS is overlooked on the initial cardiac echocardiogram, because it may be mild in its severity initially, but... |
Anomalous left pulmonary artery(pulmonary artery sling) is a congenital anomaly in which the vascular structure arises either from the posterior surface of the right pulmonary artery, or from the main pulmonary artery and courses to the left lung between the posterior surface of the trachea and the anterior surface of the esophagus. It may compress on the tracheobronchial tree causing... |
Fulminant hepatitis from hepatitis A in children is rare and has a low survival rate. We report a case of fulminant hepatitis from hepatitis A in a 12-year-old girl. The patient was admitted because of a three day history of fever, epigastric pain and vomiting. On her second hospital day, she had insomnia, anxiety, dysthesia, continuous fever, vomiting and nausea.... |
Morganella morganii, a gram-negative bacillus and part of normal faecal flora, is recognised as a common cause of urinary tract infection. We report a rare case of subdural abscess caused by M. morganii in an infant. It was secondary to purulent meningitis. The patient improved with treatment that consisted of surgical excision and systemic antibiotics. |
The deficiency of enzyme hypoxanthine-guanine phosphoribosyltransferase(HPRT) results in hyperuricemia and subsequently manifests in diverse symptoms. Lesch-Nyhan syndrome is a disorder characterized by hyperuricemia, mental retardation, choreoathetosis, spasticity and self-mutilation, resulting from complete deficiency of the enzyme, whereas partial deficiency of the enzyme shows symptoms of milder forms more often without abnormal neurologic signs. A 7-year-old boy with normal growth and... |
Chondrodysplasia punctata is a group of heterogeneous bone dysplasia characterized by punctate calcifications of the cartilage, frequently associated with a shortening of the limbs, cataracts, icthyosis and alopecia, alterations of the nervous system, and mental and growth deficiencies. Our case presented findings of the rhizomelic chodrodysplasia punctata : a characteristic face, a sucking difficulty and a short neck. Skeletal radiographies... |
A 13-year-old boy was admitted via emergency room with dyspnea after vigorous coughing. Subcutaneous emphysema was palpated on both eyelids and around the neck. Breathing sound was slightly wheezy. On initial chest roentgenogram no parenchymal lesion or pneumothorax except subcutaneous emphysema on the thoracic wall was found. On the second day of hospitalization he showed agitation much more severe than... |
Isolated relapse of myeloid leukemia as a granulocytic sarcoma(GS) following allogeneic bone marrow transplantation(BMT) is very rare manifestation, and usually associated with a poor prognosis. We report a case of isolated intracranial GS in an infant with myelodysplastic syndrome(MDS) following unrelated BMT. A 7 month-old girl was diagnosed with refractory anemia with excess blasts (RAEB). During observation for a couple... |
3-Methylcrotonylglycinuria is an autosomal recessive inborn error of leucine catabolism that results from the deficiency of 3-methylcrotonyl-CoA carboxylase(3-MCC). In 3-MCC deficiency 3-methylcrotonyl-CoA, may form glycine and carnitine conjugates. The primary metabolites are 3-hydroxyisovaleric acid(3-HIVA), 3-hydroxyisovaleryl carnitine(3-HIVC) and 3-methylcrotonylglycine(3-MCG). 3-hydroxyisovaleric acid(3-HIVA) and 3-methylcrotonylglycine(3-MCG) are increased in urine, and 3-hydroxyisovaleryl carnitine(3-HIVC) is found in blood and urine. 3-MCC is one of the... |
Biliary atresia is a progressive obliterative cholangiopathy. However, the actual causes remain unknown, although a number of factors such as developmental malformation, viral infection, toxicity of bile constituents, and anatomic abnormality in the hepatobiliary system have been considered. Recently, several studies have been done to find out specific gene expression. Some cases of biliary atresia are associated with anomalies of... |
Kikuchi-Fujimoto disease(KFD), also known as histiocytic necrotizing lymphadenitis, is a self-limited systemic illness and it has the pathognomonic histological appearance of lymph nodes. KFD is rarely associated with systemic lupus erythematosus (SLE). The diagnosis of KFD can precede, postdate or coincide with the diagnosis of SLE. Our case describes a young woman, originally diagnosed as having Kikuchi's disease by lymph... |
