PURPOSE: Recent studies show that chorioamnionitis has an important role in the pathogenesis of bronchopulmonary dysplasia(BPD) and it induces thymic involution. The purpose of this study is to test the usefulness of thymic size at birth as a predictor of BPD. METHODS: This study was conducted on 91 very low birth weight infants of <1, 500 g with mean gestational age of 29.3 weeks and mean birth weight of 1, 161 g who were admitted at NICU of Dong Kang General Hospital for past 4 years of whom 21 infants had BPD. Thymic size was measured on routine chest radiographs taken in the first 3 hours after birth and measured as the ratio between the width of the cardiothymic shadow at the level of the carina and that of the thorax at the costophrenic angles (CT/ T). RESULTS: Correlation of thymic size with gestational age was statistically significant (P=0.003). CT/T of BPD group was smaller than that of non-BPD group (0.27+/-0.06, 0.33+/-0.07, respectively, P<0.01). A significant positive correlation between small thymus at birth and BPD was detected (P=0.003, odds ratio, 21.7), but not in other disease groups. CONCLUSIONS: We concluded that a small thymus at birth on the chest radiograph could be used as an early predictive parameter of the BPD.

Isolated submandibular suppurative sialadenitis occurring in the neonatal period is extremely rare. At present, only 15 cases of isolated submandibular sialadenitis in the neonatal period have been reported in the literature. We report a rare case of multiple deep neck abscess in association with both submandibular suppurative sialadenitis in a term neonate.

Cavernous sinus thrombophlebitis is characterized by edema of the eyelids and the conjunctivae, and paralysis of the cranial nerves. It is rare, often misdiagnosed or underestimated by neurosurgeons, and is generally related with high rates of mortality and morbidity. High rate of suspicion is required for early diagnosis, and aggressive managements can lead to better outcomes. With recent advancements in antibiotic therapies, the mortality rate has been decreased to less than 30%. However, the morbidity remains high and complete recovery is rare. A 69-year-old woman presented with headache and right ocular pain with sixth cranial nerve palsy for one week. Under the suspicion of Tolosa-Hunt syndrome, steroid treatment was done. On discharge, there was improvement in right ocular pain, but the cranial nerve palsy remained. Subsequently, the patient returned with left ocular pain, lid swelling, redness, ecchymosis of conjunctiva, and ptosis. Enhanced brain magnetic resonance imaging revealed an asymmetrically enlarged left cavernous sinus with heterogeneously enhancing contour. Intravenous antibiotics and oral steroids along with anticoagulant medications were administered.

PURPOSE: The aim of this study is to investigate the usefulness of intestinal ultrasonography (US) and upper gastrointestinal endoscopy in the early diagnosis of Henoch-Schonlein purpura (HSP) with the gastrointestinal (GI) symptoms preceding the emergence of the skin lesion. METHODS: The clinical, intestinal US and upper gastrointestinal endoscopic records of 85 patients (88 cases) with GI symptoms relating to HSP presenting between January 1999 and April 2001 were reviewed. RESULTS: 1) GI symptoms were observed in 52 cases (59%) and skin, joint, renal and scrotal manifestations were observed in 88 (100%), 64 (73%), 15 (17%), 3 cases (3%) respectively. 2) Out of 52 cases with GI symptoms, abdominal pain was observed in all cases (100%). Positive stool occult blood, nausea and vomiting, abdominal tenderness, melena or tarry stool, diarrhea, hematemesis, rebound tenderness and rigidity were observed in 28 (50%), 17 (33%), 17 (33%), 12 (23%), 6 (12%), 4 (8%), 1 (2%) and 1 case (2%) respectively in order of frequency. 3) Intestinal US examination was performed in 27 cases with HSP and GI symptoms (52 cases). Out of 27 sonographic examinations 22 showed abnormal findings. Thickening of the duodeno-jejunal wall was observed in 16 cases (73%). Free peritoneal fluid, enlarged mesenteric lymph node, ileus and abnormal gall bladder were seen in 8 (36%), 8 (36%), 4 (18%) and 1 case (5%) respectively. In three cases of HSP without GI symptoms, those changes were absent. 4) In all of five cases with HSP and GI symptoms, endoscopic study showed mucosal edema and multiple hemorrhagic erosions especially at the second portion of the duodenum. Biopsy specimens from the duodenum of 2 cases out of 5 endoscopic examinations showed acute inflammatory infiltrates in the mucosa with hemorrhage. 5) Both intestinal US and endoscopic studies were performed in 4 cases with HSP and GI symptoms simultaneously. Out of 4 those cases, 3 cases showed the thickened duodeno-jejunal wall on the intestinal US, which suggested erosive hemorrhagic duodenitis by endoscopic findings. CONCLUSION: The typical but nonpathognomonic intestinal US findings including the thickening of the duodeno-jejunal wall and upper gastrointestinal endoscopic findings including hemorrhagicerosive duodenitis, in children with GI symptoms, should be considered a manifestation of HSP, even in the absence of skin lesion.

PURPOSE: We evaluated the diagnostic accuracy and useful ness of FDG-PET to determine the proper extent of surgery in recurrent papillary thyroid cancer patients with elevated thyroglobulin levels and negative I131 WBS. METHODS: FDG-PET was performed in 16 recurrent papillary thyroid cancer patients with elevated thyroglobulin levels and negative I131 WBS. In 9 patients, FDG-PET was performed to localize the recurrent lesions. In 7 patients, the recurrent lesions were initially diagnosed by physical examination or other image studies and the FDG-PET was subsequently performed to detect additional recurrent lesions. All suspected lesions detected by FDG-PET and other studies were explored. RESULTS: Among the 9 patients in whom FDG-PET was performed to localize the recurrent lesions, the recurrent lesions were detected only by FDG-PET in 4 patients. Among the 7 patients in whom FDG-PET was performed additionally to detect additional recurrent lesions, another recurrent cervical regions were detected by FDG-PET in 2 patients. However, the same lesions were able to be identified by ultrasonography. A total of 26 cervical regions were explored in 16 patients. There were 4 FDG-PET false positive regions and 2 FDG-PET false negative regions. Unnecessary surgery was performed in 4 cervical regions in 4 patients. CONCLUSION: FDG-PET was very useful in detecting small early recurrent lesions but was unable to contribute to the detection of additional recurrent cervical regions in the pa-tients in which the recurrent lesion had already been by physical examination or other studies. Other image studies are necessary to supplement the FDG-PET in false positive or false negative cases.

Pulmonary hamartoma is uncommon benign tumor-like malformation, which comprises abnormal mixing of the normal components of the lung i.e., cartilage, fat, smooth muscle or respiratory epithelium. The majority occurs in fourth and fifth decades of life, but extremely rare in the pediatric age. Pulmonary hamartoma is clinically classified to endobronchial and intrapulmonary hamartoma. The majority of the pulmonary hamartomas have no clinical symptoms and are detected incidentally by routine chest roentgenograms. But definite diagnosis should be necessary, because of its difficulty to differentiate from malignant and inflammatory lesions. We report a case of intrapulmonary hamartoma which was detected by routine chest roentgenogram check up and diagnosed by fine needle aspiration biopsy and pathological examination with the review of the literature.

Severe cough may contribute to serous coplications such as pneumothorax, pneumomediastinum, rib fracture, subconjunctival hemorrhage, subdural hemorrhage and cough syncope. However abdominal wall hematoma is a rare complication. Because it usually presents with abdmoianal pain, abdominal wall hematoma needs to be differentiated from the acute surgical abdomen. A 78-year-old woman was admitted with right lower quadrant abdominal pain and a palpable mass for several days. She experienced abdominal pain after violent coughing associated with an upper respiratory tract in fection. Abdominal computed tomography revealed an approximately 7×4 cm sized, ill-defined, soft tissue density lesion in the right lower posterolateral abdominal wall. An abdominal wall hematoma was diagnosed. After admission, she had persistent right lower abdominal pain and an increasing mass. The mass was surgically removed and she was discharged without complications. In summary, when a patient complains of abdmonial pain after severe coughing, an abdominal wall hematomas as a differential diagnosis must be considered.

Migraine equivalents include cyclic vomiting, acute confusional states, and benign paroxysmal vertigo. Cyclic vomiting is characterized by recurrent, sometimes monthly, boults of severe vomiting that may be so intense dehydration and electrolyte abnormalities occur, particularly in an infact. We experienced a 3-year-old girl who showed manifestations of cyclic vomiting and abdominal pain. We report this case with a review of related literatures.

PURPOSE: Urachal anomalies are rare but are known to develop several complications, especially infection. Moreover, uniform guidelines for management have not been presented because of the variable clinical characteristics of these anomalies. The purpose of this report is to review our experience with urachal anomalies and attempt to determine the optimal management. METHODS: We retrospectively reviewed the records of fourteen children with a variety of urachal anomalies who had been treated from January 1996 to June 2005 at Dong Kang General Hospital. RESULTS: The age distribution of the patients(mean age; 3.8 years) was six neonates, one infant, five preschool-age and two school-age children. The male to female ratio was 1:1. Six cases of urachal cyst, four cases of patent urachus, two cases of urachal sinus and two cases of urachal diverticulum were found. Three patients with patent urachus and one with urachal cyst had hydronephrosis. Other associated anomalies included an inguinal hernia in one patient with urachal sinus and a vesicoureteral reflux in one patient with urachal diverticulum. As a first-line diagnostic tool, high-resolution ultrasound examination was performed in thirteen cases and computed tomography in one case. Surgical excision was performed in nine patients with urachal anomaly. Five cases out of six neonatal cases experienced spontaneous improvement during a three-month follow up period. Due to frequent infection of the umbilicus, surgical excision was performed on one neonate with urachal sinus. CONCLUSION: All patients with urachal anomalies should undergo investigation for associated anomalies. The neonate with urachal anomalies, especially patent urachus, do not require surgical excision unless the patient has multiple episodes of recurrent infection.
