A Case of Disseminated Lymphangiomatosis Involving Mediastinum, Bone, Spleen and Retroperitoneum in an Asymptomatic Healthy Child
Kyung Hee Yoon, Seung Ju Ha, In Sook Park, Hyun Woo Goo, Jong Hyun Yoon
Clin Exp Pediatr. 2001;44(11):1326-1329.   Published online November 15, 2001
Lymphangiomatosis, a benign tumor consisting of a cluster of dilated lymphatic channels, is very unusual. Most lymphangiomatoses are found in the neck and head area. Less than 5% are diagnosed intraabdominally and they are very infrequently encountered in the retroperitoneal area. Herein, we report a rare case of asymptomatic lymphangiomatosis of a 13 year-old boy during a routine chest...

Clin Exp Pediatr. 2001;44(11):1320-1325.   Published online November 15, 2001
Wernicke,s encephalopathy(WE), a neurological disorder caused by thiamine deficiency, is characterized by the triad of ocular symptoms, ataxia, and mental confusion. More than 90% of the cases are observed in chronic alcoholics. Other conditions less frequently associated with WE are anorexia nervosa, prolonged parenteral nutrition, hemodialysis, uremia, hyperemesis gravidarum, gastroplasty for morbid obesity, and acquired immunodeficiency syndrome(AIDS).

A Case of Chronic Pneumonitis of Infancy in Pediatric Interstitial Lung Disease
Hyun Oh Jang, Se Chang Ham, Young Kyoun Kim, Se Wook Oh, Yong Won Park
Clin Exp Pediatr. 2001;44(9):1085-1090.   Published online September 15, 2001
The interstitial lung diseases(ILD) comprises a large, heterogeneous group of disorders characterized by derangement of alveolar walls and alveolar capillary unit causing restrictive pulmonary dysfunction and disordered gas exchange. It is rare, especially in children, and the opinions on investigation and treatments are controversial. The classification of adult ILD is applied to that of children. But considering occurrence during the developing state of lung...
Three Cases of Acute Scrotal Disorders in the Neonate
Ja Yun Yun, Min Kyoung Kwon, Mi Ran Kim, Kon Hee Lee, Kwang Nam Kim, Ho Hyun Jeong
Clin Exp Pediatr. 2001;44(7):841-846.   Published online July 15, 2001
Acute scrotal disorders(ASD) in neonates-especially the torsion of testes- are rare, and the clinical presentations are quite different from those of adolescents or adults. The neonates with ASD are generally afebrile and do not show typical symptoms. Early diagnosis and proper treatment of ASD are very important but the differentiation of torsion and orchitis is not easy in neonates. The...

Colonic Transit Time in Chronic Constipated Patients
Je Eun Choi, Im Jeong Choi, Jung A Lee, Sung Mi Kim, Jin Hwa Jeong, Jeong Ho Lee
Clin Exp Pediatr. 2001;44(7):752-757.   Published online July 15, 2001
Purpose : In most instances, constipation is considered as idiopathic or functional. The total colonic transit time, traced by radio-opaque markers, makes possible the identification of the colon segment that has the motility alteration that causes constipation. We measured the total and segmental colonic transit time in children with chronic idiopathic constipation and compared the results with those without constipation...

A Case of Protein-losing Enteropathy in Congestive Heart Failure : Resolution with Prednisolone
Jong-Woon Choi
Clin Exp Pediatr. 2001;44(5):587-591.   Published online May 15, 2001
Protein-losing enteropathy can result from primary or secondary intestinal lymphangiectasia. Secondary intestinal lymphangiectasia develops as a result of lymphatic obstruction or elevated lymphatic pressure. Cardiac lesions such as constrictive pericarditis, post-Fontan procedure state, and chronic congestive heart failure increase lymphatic pressure and may cause intestinal lymphangiectasia and protein-losing enteropathy. An 11-year-old girl who underwent corrective surgery for Tetralogy of Fallot...

Effect of Granulocyte-macrophage Colony-stimulating Factor in Neonatal Infection
Il-Young Jo, Sang-Hyun Byun
Clin Exp Pediatr. 2000;43(12):1552-1557.   Published online December 15, 2000
Purpose : Neutrophils are central to the defences against bacterial infection, and in neonates the number of neutrophils are decreased due to inhibited production and phagocytic function. This induces high mortality rates in infants suffering from neonatal sepsis. Exogenous GM-CSF can increase the number of neutrophils and improve the phagocytic function. To establish the most cost effective dose of exogenous...

Jin Choi, Soo Jung Lee, Dae Kyun Koh
Clin Exp Pediatr. 1999;42(11):1574-1578.   Published online November 15, 1999
The most clearly delineated condition with prominent cutaneous leukocytoclastic vasculitis which presents to a pediatrician is Henoch-Schönlein purpura. There is general agreement that in Henoch-Schönlein syndrome the skin manifestations have a very benign long-term course and that corticosteroids are of little value. Dapsone appears to be of special value in diseases characterized by an accumulation of polymorphonuclear neutrophils notably leukocytoclastic...

Clin Exp Pediatr. 1999;42(10):1452-1458.   Published online October 15, 1999
Primary intestinal lymphangiectasia is a rare congenital disorder characterized by diffuse or localized ectasia of the enteric lymphatics, often in association with lymphatic abnormalities elsewhere in the body. The pathogenesis of these abnormal lymphatic structures is uncertain. Ectatic lymphatics may be located in the mucosa, submucosa, or subserosa, leading to a loss of protein and lymphocytes into the gut or...

A Case of Acute Myeloblastic Leukemia Transformed from Transient Myeloproliferative Disorder with Down Syndrome
Jae Eun Lee, Seung Woo Baeck, Wan Seob Kim, Chun Hee Lee
Clin Exp Pediatr. 1999;42(1):128-132.   Published online January 15, 1999
Individuals with Down syndrome have a high incidence of hematologic diseases such as transient myeloproliferative disorder(TMD) & acute leukemia. Because it is difficult to distinguish TMD from acute myeloblastic leukemia, the diagnosis in neonate, who have Down syndrome, should be made with extreme caution. TMD usually undergoes spontaneous remission within a few months, but acute leukemia can develope after remission...
