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: We analyzed pediatric death patients who visited Dong-Kang Hospital emergency center, in order to minimize unexpected pediatric deaths. METHODS: The authors analyzed retrospectively the medical records of 110 pediatric patients who died before and within 24 hours after admission to the emergency center of Ulsan Dong-Kang General Hospital from January 1997 to December 2002. RESULTS: We classified three categories by the cause of death, accident group(AG) 46 cases(41.8%), disease group(DG) 37 cases(33.6%), unknown cause group(UG) 27 cases(24.6%) respectively. The most common age was between two and five years of age(50.0%) in AG, under one month (40.5%) in DG, between one month and one year(51.9%) in UG respectively. The most common season was summer(37.0%) in AG, winter(51.4%) in DG, spring(37.1%) in UG respectively. The most common time on arrival was from 13:00 to 18:00(37.0%) in AG, from 7:00 to noon(43.2%) in DG, from midnight to 6:00(29.6%) and from 7:00 to noon(29.6%) in UG respectively. The most common type of accident was traffic accident(47.8%). The most common cause of death in DG was respiratory disorder(40.5%). Sudden infant death syndrome was the most common(37.1%) in unknown cause of death. CONCLUSION: Accidental injuries and severe chronic illnesses are the major cause of unexpected pediatric death. Legislation related to accidents and a parents teaching program for emergency situations are necessary to decrease cases of unexpected pediatric death.

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.

PURPOSE: To evaluate of the role in carcinogenesis of p53 over-expression and bcl-2 inhibition in early gastric and advanced gastric cancers, we investigated the immunohistochemical tissue status of 31 primary early gastric-cancer patients and 31 primary advanced gastric-cancer patients. METHODS: DO7, the monoclonal antiserum to the P53 protein, and clone 124, the monoclonal antibody to the bcl-2 protein, were used for the immunohistochemical analysis of the 31 surgically resected primary early gastric cancer specimens and the 31 surgically resected advanced gastric-cancer specimens. The expressions were scored and divided into negative, positive, low expression, and overexpression. RESULTS: The clinicopathologic parameter; tumor depth of invasion, histologic type, and differentiation, were not related with the expression status of p53 or bcl-2. Of the 31 primary early gastric-cancer patients, 14 exhibited p53 overexpression and 16 showed negative the bcl-2 expression; 5 cases had both p53 overexpression and negative bcl-2 expression. Of the 31 advanced gastric cancer patients, 19 showed the p53 overexpression, and negative bcl-2 expression, 15 exhibited both p53 overexpression and negative bcl-2 expression. CONCLUSION: These results suggest that cell cycle alteration and apoptosis control by p53 and bcl-2 may play roles in the carcinogenesis of gastric cancer. However, there are many other mediators that may facilitate carcinogenesis. This study proved that bcl-2 is a valuable prognostic factor.

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.

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.
