To evaluate the effect of a new topical anesthetic cream (EMLA : Eutectic mixture of local anesthetics) on reducing pain associated with DPT vaccination, we conducted a clinical observation on eighty infants who were brought to well baby clinic of Yeungnam University Hospital for DPT vaccination. 80 Infants, who were between 2 months and 8 months in age, were divided into two groups. EMLA treated group and control group. Male to femle sex ratio was 1.4 to 1. EMLA cream was applied 60 minutes before DPT vaccination, the effect of reducing pain was assessed by using McGrath's face scale, Oucher pain scale and modified behavioral pain scale (MBPS) and also evaluated by measuring the duration and time of crying (the time of the first crying after iniection, duration of the first crying, total duration of crying). The scores of those scales were lower in EMLA treated group than in control group significantly (P<0.01 in McGrath's face scale. MBPS and p<0.05 in Oucher pain scale). There was no difference in the time of the first crying after vaccination in both groups. The duration of the first crying was shorter in EMLA treated group than control group of crying was also shorter in EMLA treated group (EMLA treated group 9.0±12.5 sec, p<0.05). Transient skin erythema was noted in 5 infants after EMLA application, but no other adverse effects were observed. We conclude that the application of EMLA cream before vaccination seems to be an effective and safe way to reduce the pain from vaccination, but it takes usually 60 minutes to get the anesthetic effect of EMLA and it is expensive, so EMLA cream can not be recommended in routine vaccination in infants now.

Laparoscopic distal gastrectomy for gastric cancer has rapidly gained popularity because of its short-term benefits, including less blood loss, less postoperative pain, earlier postoperative recovery, and shorter hospital stay, compared to the conventional open method. Although the long-term results of phase III trials have yet to be published, laparoscopic distal gastrectomy is now considered to be accepted for early-stage gastric cancer. As advances in instruments and the accumulation of laparoscopic experience increase, laparoscopic distal gastrectomy is being used for advanced gastric cancer. However, due to the technical difficulty of performing D2 lymphadenectomy, this application remains controversial. Well-designed clinical trials will clarify the surgical feasibility and oncological safety of laparoscopic distal gastrectomy for advanced gastric cancer in the near future.

OBJECT: Pre-ALL is a very rare preteukemic state, which percedes acute lymphocytic leukemia, while MDS(pre-ANLL), usually the well-known type of preleukemic state, precedes acute non-lymphocytic leukemia. Initially it shows transient pancytopenia without any evidence of leukemia in bone marrow findings, followed by acute lymphocytic leukemia after recovery from pancytopenia of a short period within weeks or months. We report a case with pre-ALL in childhood. CASE: A 15-month-old male baby was admitted with the complaints of fever and cough for 5 days and pallor for 2 weeks prior to admission. On admission, CBC showed pancytopenia without any evidence of leukemia, which was recovered spontaneously in a short period, and then was followed by acute lymphocytic leukemia of CALLA negative, early pre-B cell type. During antileukemic chemotherapy, he had suffered from severe bacterial infections and was finally died of sepsis 8 months after first admission. CONCLUSION: We report a case of pre-ALL in childhood, which was preceded by CALLA negative, early pre-B cell ALL, with a review of the literatures, briefly.

Purpose: Dislocation is the second most common cause of failure, after implant loosening, in revisional THA (Total hip arthroplasty), and its evaluation and treatment still remain controversial issue. This study was undertaken to evaluate the risk factors after THA using the posterolateral approach and posterior soft tissue repair. Materials and Methods: Between January 1998 and May 2003, 211 consecutive primary total hip replacement arthroplasties using the posterolateral approach and posterior soft tissue repair were performed by the same surgeon. To compare the dislocation groups (6 cases) with the non-dislocation groups (205 cases), we randomized 120 of the non-dislocation cases. The risk factors for hip dislocation were categorized into patient factors and surgical factors. Patient factors included gender, age, preoperative diagnosis, underlying systemic disease, and alcoholic history. Surgical factors included position of the component (acetabular version and inclination, femoral anteversion), leg length discrepancy, and sum of anteversions of the cup and stem. Their parameters were measured on postoperative radiographs. Statistics were performed with Fishe`s Exact test and T test. Results: Dislocations occurred at an overall incidence rate of 2.8% (6/211cases). There were 4 (1.9%) cases of anterior dislocations and 2 (0.9%) cases of posterior dislocations. Dislocations occurred on average at postoperative day 6.1 and all dislocated hips were reduced with the closed method, except for one case that was treated surgically. There was no statistical significance in patient factors between the two groups, except for neurologic disease and alcoholic history. However, the sum of the acetabular and femoral anteversions in the anterior dislocation group was larger than that of the non-dislocation group by approximately 19 degrees. Conclusion: Our results demonstrated that by using the posterior approach and repair of soft tissue, the posterior dislocation rate after total hip replacement arthroplasty can be reduced and the sum of the acetabular and femoral anteversions had more influence on dislocations after THAs than did either anteversion alone.

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analyzed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent 6 years. The most common tumor was thymoma (9 cases), and teratoma (6 cases), lymphoma (6 cases), bronchogenic cyst (4 cases), neurogenic tumor (4 cases), pericardial cyst (1 case) were next in order of frequency. There were 5 cases of thymoma showing homogenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases. A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomonic fat, and calcified density were seen only in 4 cases. 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma (3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor (2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, 1 was located in subcarinal and 1 was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

The goal of therapy in patients with traumatic carotid-cavernous fistulas is to occlude the fistula preferably while maintaining the carotid blood flow. Since the introduction of the concepts of detachable balloon technique to occlude arteriovenous fistulas, the technique has become the treatment of choice in the management of traumatic carotid-cavernous fistulas. The major symptoms of traumatic CCFs are (1) pulsating exophthalmos, (2) orbital and cephalic bruit and murmur, (3) headache, (4) chemosis, (5) extraocular palsies, and (6) visual failure. Traumatic CCFs are combined with multiple associated lesion. We tried the occlusion of fistulas using Goldvalve balloons in 8 consecutive cases of traumatic CCF and the result of our experience is reported. Transarterial approach with manually-tied latex balloons is tried in all cases and the fistulas was successfully occluded in all cases. In 5 cases, the internal carotid artery was preserved and the arterial lumen was occluded along with fistula opening in cases. In one case, surgical ligation was done because of symptoms recurred and incomplete occlusion of fistula. We experienced hemiparesis as a major complication in one case during occlusion tolerance test, which was remitted spontaneously. The results of Debrun balloon treatment were relatively excellent. We consider that the first choice of treatment of traumatic CCF is occlusion of the fistula by a detachable balloons.

Platelet-derived growth factor(PDGF) is known to accelerate soft tissue fracture and periodontal bone healing, but little information is available for characterizing the healing of articualr cartilage. This study was designed to demonstrate the regeneration potential of pasteurized autogeneous osteochondral graft when PDFG was applied locally in vivo. Eighteen rabbits in two groups were used in the experiment. The free osteochondral fragment(1x1x1 cm) were taken from distal femur. The fragment were pasteurized in 65degrees C for 5 minutes. In experimental group(group II), the fragment were soaked in 0.25 mg/ml of recombinant human PDGF mixed 5 ml normal saline and reimplanted to the resected site, and followed with local administration of 0.25 mg/ml PDGF to knee joint. In control group(group I), the pasteurized fragment were reimplanted in the resected site without any treatments. The histologic characteristics of the transplanted autografts for three rabbits in each group were observed at 3, 5 and 7 weeks postoperatively. The results were as follows; Group II revealed the more favorable regeneration of articular cartilage, less arthritic changes and more mature arrangement of chondrocytes than group I. Even thought the cartilage is avascular and the regeneration capacity of pasteurized cartilage is severely limited, the regeneration of grafted articular cartilage is thought to be accellerated by increased newly formed blood vessels and soft tissues due to the diffusion of PDGF on grafted cartilage, and probably also by differentiation of mesenchymal cells in the initial stage of experiment. The results of this study suggest that local administration of PDGF could be used for the treatment of posttraumatic or degenerative arthritis and various cartilage damages.

BACKGROUND: gamma-Aminobutyric acid (GABA), the principal inhibitory neurotransmitter, activates persistent low amplitude tonic currents in several brain regions, in addition to conventional synaptic currents. Tonic conductance is highly sensitive to low concentrations of volatile anesthetics and therefore might contribute to amnestic properties. We compared the properties of GABAergic tonic currents mediated by sedative-amnestic midazolam and anesthetic propofol in rat hippocampal neurons. METHODS: Patch clamp techniques were used to characterize the GABAergic currents recorded in CA1 pyramidal neurons in rat hippocampal slices. The amplitude of the tonic currents and the decay of miniature inhibitory postsynaptic currents (mIPSCs) were measured after administration of midazolam or propofol. RESULTS: Both midazolam and propofol caused concentration dependent increases in the tonic currents. The enhancement of the tonic currents by midazolam concentrations of greater than 0.5 microM caused no further increase in current amplitude. Propofol continued to increase with concentrations over the range tested (0.1-10 microM). Low concentrations of midazolam 0.01 microM and propofol 0.5 microM selectively enhanced the tonic currents but failed to alter mIPSCs. CONCLUSIONS: Low concentrations of midazolam and propofol selectively enhanced the tonic currents but not synaptic currents of rat hippocampal pyramidal neurons. Unlike midazolam, the response to propofol did not become saturated and had a greater effect on the tonic currents.
