PURPOSE: The aim of this study was to compare the results of the lateral entry pin technique and the crossed pin technique in treatment of Gartland type III humerus supracondylar fracture. MATERIALS AND METHODS: Seventeen patients (group I) underwent surgery using the lateral entry pin technique, and 33 patients (group II) underwent surgery using the crossed pin technique for Gartland type III humerus supracondylar fracture in Hanyang University Seoul Hospital between January 2011 and January 2014. Maintenance of reduction was compared between the 2 surgical techniques by measuring changes in Baumann angle and lateral humerocapitellar angle after surgery and after pin removal in groups I and II. In addition, the final carrying angle and level of loss of functional movement were measured for comparison of clinical results between the 2 groups. Occurrence of ulnar nerve palsy in the 2 groups was also examined. RESULTS: The mean Baumann angle and lateral humerocapitellar angle changes were 3.3degrees and 3.7 in group I and 3.1degrees and 3.4degrees in group II, respectively. No statistically significant differences were found between the 2 groups. Clinical results showed that the changes in the final carrying angle and range of motion were 2.9degrees and 2.6degrees in group I and 2.6degrees and 3.0degrees in group II, respectively, indicating no significant differences between the 2 groups. In terms of nerve damage, 1 patient in group II had temporary iatrogenic ulnar nerve palsy. CONCLUSION: The lateral entry pin technique may be regarded as an appropriate treatment that reduces the risk of iatrogenic ulnar nerve palsy and provides satisfactory results in Gartland type III humerus supracondylar fracture patients.

Massive hemoptysis represents a major medical emergency that is associated with high mortality. The causes of hemoptysis are various and include pulmonary and cardiovascular disorders and trauma. The causes of pulmonary disorder are tuberculosis, bronchiectasis, abscess, malignancy, bronchitis, and fungal infection. The causes of cardiovascular disorder are mitral stenosis, pulmonary embolism, and congestive heart failure. A fistula between an aortic aneurysm and the pulmonary parenchyma is one of the causes of hemoptysis, but it is a rare. However, if undiagnosed, it is a uniformly fatal cause of massive hemoptysis. This is a case of bleeding from a fistula between an aortic arch aneurysm and a lung parenchyma in a patient with an aortic arch aneurysm who presented with massive hemoptysis. He had suffered intermittent hemoptysis since he was diagnosed with an aortic arch aneurysm three years before. A high clinical suspicion must be maintained when a history of intermittent hemoptysis is obtained in patients with an aortic aneurysm or prior aortic graft surgery.

Medullary thyroid carcinoma accounts for 3% of all thyroid gland malignancies. It commonly metastasizes to liver, lung, and bone. It rarely metastasizes to skin, and only a few such cases have been documented. Cutaneous metastasis suggests a poor prognosis, with a mean survival of 7.5-19 months. The most effective treatment for skin metastasis is complete surgical removal of all local and regional lesions. The response to systemic chemotherapy is typically poor. We report a case of medullary thyroid carcinoma with cutaneous metastases, which responded to chemotherapy.

OBJECTIVE: Chlamydia trachomatis is one of the most common causative microorganisms in pelvic inflammatory disease. The symptom of Chlamydia infection is nearly absent or weak in many cases, but its complication is clinically very important because of tubal obstruction, infertility, tubal pregnancy, and recurrent pelvic inflammatory disease. This study was performed to investigate the prevalence rate and clinical characteristics of Chlamydia trachomatis. METHODS: From May, 2001 to April, 2002, in Daerim St. Mary's Hospital, OB-Gyn department, the 68 inpatients of pelvic inflammatory diseases and 607 outpatients of routine gynecologic examination were studied on history taking, physical examination, laboratory test, and polymerase chain reaction for the detection of Chlamydia trachomatis. RESULTS: The prevalence rate of Chlamydia trachomatis was 20.6% (14/68) in pelvic inflammatory disease and 8.6% (51/593) in routine gynecologic examination. As regarding the age distribution of Chlamydia trachomatis positive group was the largest portion in the twenties, and symptom-free group was about 40%. Chlamydia infection was related to the history of artificial abortion, and showed no significant difference in parity. Most common site of infection was uterine cervix, and mixed infection rate with other bacteria was 43.1%. The treatments were given medically in 58 cases, surgically in 6 cases, and laparoscopy in 1 case were performed. CONCLUSION: Although the prevalence rate of Chlamydia infection is high in sexually active age group and Chlamydia infection has a serious bad effect on reproduction, the disease detection is difficult because symptom is weak or absent, but it reveals good cure rate. Therefore the screening and treatment of Chlamydia trachomatis are necessary to decrease the prevalence and prevention of complication.

PURPOSE: The aim of this case report is to present the longitudinal results of sinus grafting using a new demineralized bovine bone material (DBBM) in human cases. METHODS: A patient with a resorbed maxilla was treated by maxillary sinus grafting using a new deproteinized bovine bone material. After a healing period of 6.5 months, three implants were placed and restored. The patient was periodically recalled and followed up for 5 years after restoration. RESULTS: Twelve partially edentulous patients (average age, 55.7 years) were followed up. All patients had insufficient residual height in their maxillary posterior area and underwent maxillary sinus graft surgery to increase the height of their maxilla. In all, 27 fixtures were placed in the augmented bone area. On average, 8.6 months later, implants were loaded using provisional or final restorations. The observation period ranged from 27 to 75 months (average, 43.3 months), and the patients did not show any severe resorption of the graft material or any infection during this time. CONCLUSIONS: Our results show that the new DBBM is useful for a maxillary sinus graft procedure. Good healing responses as well as reliable results were obtained for an average follow-up period of 43.3 months.

Atrial Septal Defect(ASD) is usually suspected clinically but requires a confirmative diagnostic procedure before surgical repair. Conventional transthoracic echocardiography has relatively high sensitivity and specificity for ASD, but difficulty in visualizing the ASD occasionally. Transesophageal echocardiography has special advantages for investigating the posteriorly located cardiac structures, including the atrial septum, which is imaged perpendicularly at a relatively short distance. We describe a case in which ostium secundum ASD was not visualized by conventional transthoracic echocardiography, but was diagnosed confidently by transesophageal echocardiography. It is concluded that transesophageal echocardiography appears to be a promising diagnostic tools for the evaluation of ASD on the basis of its ability to provide excellent imaging of the entire atrial septum and related posterior cardiac structures.

PURPOSE:Present evidences suggest that Ureaplasma urealyticum is a cause of pneumonia, septicemia, and bronchopulmonary dysplasia (BPD) in newborn infants, particularly those born prematurely. The purpose of this work was to examine the relationship between Ureaplasma urealyticum in the tracheal aspirates and adverse outcomes, such as BPD and early onset neonatal sepsis in premature infants. METHODS:A polymerase chain reaction (PCR) was performed on tracheal aspirates collected within 24 hour after birth in 176 premature infants less than 35 weeks of gestation and admitted to the neonatal intensive care unit of Bundang CHA Hospital. RESULTS:U. urealyticum was detected in 37 of 176 preterm infants (21.0%). Gestational age (29+5+/-2+5 wk vs. 30+6+/-2+5 wk, P=0.013) and birth weight (1.39+/-0.44 kg vs. 1.59+/-0.55 kg, P=0.037) were lower in the U. urealyticum-positive group compared to the control group. The incidence of early onset neonatal sepsis (16.2% vs. 6.5%, P=0.045) and BPD (45.9% vs. 29.5%, P=0.047) was higher in the U. urealyticum-positive group compared to the control group, but the severity of BPD was not different between two groups. However, multiple logistic regression analysis revealed that the presence of U. urealyticum was not independently related to the development of early onset neonatal sepsis and BPD. CONCLUSION:The results suggest that colonization of the lower respiratory tract by U. urealyticum might not be related to the development of neonatal sepsis and BPD directly in preterm infants.

BACKGROUND: Cardiopulmonary bypass (CPB)-induced hemostatic defects may result increased possibility of excessive hemorrhage and additional multiple transfusion reactions or reoperation. Particularly, fibrinolytic activation and decreased platelet count and function by CPB were proposed as a predictor of hemorrhage during postoperative periods in several reports. MATERIALS AND METHODS: Present study, which was conducted in 20 adult patients undergoing CPB, was prospectively designed to examine the hematologic changes, including fibrinolytic activation during and after CPB and to clarify the relationships between these changes and the magnitude of the postoperative nonsurgical blood loss. The serial blood samples for measurment of hematologic parameters were taken during operation and postoperative periods. Blood loss was respectively counted via thoracic catheter drainage at postoperative 3, 6, 12, 24, 48 hours and total period. RESULTS: The results were obtained as follows:Platelet count rapidly declined following CPB (p<0.01), which its decreasing rate was an inverse proportion to total bypass time (TBT, r=0.55, p=0.01), And platelet count in postoperative 7th day was barely near to its control value. Fibrinogen degradating product (FDP) and D-dimer level significantly increased during CPB (p<0.0001, p<0.0001, respectively), and both of fibrinogen and plasminogen concentration correlatively decreased during CPB (r=0.57, p<0.01), implying activation of fibrinolytic system. Postoperative bleeding time (BT), postoperative activated partial thromboplastin time (aPTT) and postoperative prothrombin time (PT) were significantly prolonged as compare with each control value (p=0.05, p<0.0001, p<0.0001, respectively). Total blood loss was positively correlated with patient's age, aortic clamping time (ACT) and TBT, while there was negative correlation between platelet count and blood loss at pre-CPB, CPB-off and the 1st postoperative day, and in some periods. Postoperative aPTT and postoperative PTwere positively related to postoperative 6 hr and 48 hr blood loss (r=0.53, p=0.02; r=0.43, p=0.05) but not to total blood loss, whereas there was no relationship between postoperative BT and blood loss at any period. CONCLUSIONS: These observations suggest that CPB results various hematologic changes, including fibrinolytic activation and severe reduction in platelet count. Diverse factors such as age, platelet count, ACT, TBT and postoperative aPTT and PT may magnify the postoperative bleeding. This study will be a basic reference in understanding CPB-induced hemostatic injuries and in decreasing the postoperative hemorrhage.

This study was designed to investigate any correlation between the mechanism of pain development and changes of histochemically-reactive zinc contents in the rat spinal cords following peripheal nerve ligation. Male Sprague-Dawley rats (270 ~290 g) were used for this study. We ligated a left-sided lumbar spinal nerve with silk under anesthesia using pentobarbital (50 mg/kg). Semmes-Weinstein monofilaments (Stoelting Company, Wood Dale, IL) was used to test for mechanical hyperalgesia. 30 micrometer-thick spinal cord cryosections were stained by automet-allography (Danscher, 1981). The density of zinc was significantly decreased in zinc concentration in the dorsal horn of 4th, 5th and 6th lumbar segments at 5 and 10 days after the spinal nerve ligation. Here, zinc depletion was apparent in superficial gray matter, especially layer III-IV. In addition the nerve ligated rats showed lower pain threshold. This increased pain sensation might be related with lowered vesicular zinc level in the superficial gray matter in the spinal cord. The present findings offer a proposed link between zinc and pain. Our interpretation is that there may be an extension of fine primary afferent fibers into lamina III and possibly lamina IV following peripheral nerve ligation. If further work bears out this conclusion, this would provide a possible explanation for the chronic pain states that sometimes follow peripheral nerve damage.
