OBJECTIVE: Despite advances in both operative techniques (endovascular coiling or surgical neck clipping), management of basilar artery aneurysms has not been completed. The goal of this retrospective study is to evaluate endovascular coiling compared with surgical neck clipping of upper basilar artery aneurysms. METHODS: From january of 1990 to December of 2001, the authors treated 31 cases of upper basilar artery aneuryms. Among of those upper basilar artery aneurysms, 22 patients received surgical neck clipping and 9 patients recevied non-surgical endovascular coiling. Results from outpatient follow-ups for 12 months after operation were classified with Glasgow outcome scale (GOS) analyzed respectively. RESULTS: Overall, 11(50%) of the surgical neck clipping patients and 6(66.7%) in endovascular coiling patients were showed good outcomes(GOS 4~5). Morbidity of the surgical clipping is about 22.7%(5/22) and the endovascular coiling is about 22.2%(2/9) There were two death in the surgical clipping group due to vasospasm and brain stem infarction, but none in the endovascular coiling group. The major causes of surgical morbidity were direct brain damage, perforator occlusions, vasospasm and meningitis. Endovascular coiling group was shorter hospital stay and lesser hospital expenses than surgical neck clipping group. CONCLUSION: Non-surgical endovascular coiling of upper basilar artery aneurysms is considered to be useful alternative treatment in improving short-term prognosis(12 months follow-ups) and reducing medical expenses compared to surgical neck clipping although long-term follow-up is needed.

The Rathke's cleft cyst is generally thought to be derived from Rathke's pouch remanants. Symptomatic Rathke's cleft cyst was first described by Goldzieher in 1913. Recently, several cases have been reported by the gradual development of diagnostic methods. We present our experience of a rare case of ectopic suprasellar Ratheke's cleft cysts. The cysts were located in the interpeduncular cistern. We performed a successful operation and made immunohistochemical examinations.

Gorham's syndrome is a rare disorder involing a proliferation of vascular channels associated with extensive loss of bony matrix. It starts in bone, but it may secondarily involve soft tissue and adjacent bones. Although the osteolysis usuakky arrests spontaneously, its biologic behavior is difficult to predict. The mechanism of steolysis is unkown, and the role of osteoclasts is controverwial We have experienced one case of Gorham's syndrome affecting the scapula and clavicle, which is reported in this paper with brief review of literature.

The aims of treatment of children with CDH untreated until walking age should be to reestablish the mechanics of the hip joint and avoid complications, especially avascular necosis, thus delaying the devlopment of osteoarthritis. In the child who is first seen between the ages of one and three years, considerable controversy still exists as to the merit of closed versus operative management. The average 29.3 months follow-up results in fifty congenitally dislocated hips in forty-five children with were between six and thirty-six months old when treatment was begun have been reviewed at the Department of Orthopaedic Surgery, In Je University, College of Medicine, Paik Hospital from June, 1979 to Aug, 1989. The results of this study were as follows: 1. Factors affecting method of treatment were age, degree of dislocation and acetabular index; A. Age 1) The children below ages of 18 months were treatment by closed reduction. 2) The children below ages of 18 months were treatment by open reduction with concomittant procedures. B. Degree of dislocation: Open reduction was more frequently reguired in higher degree of dislocation. C. Acetabular index: It was little influenced on method of treatment. 2. The complications were persisten subuxation (3 cases), temporary irregular ossification (16 cases) and avascular necrosis (1 cases).

BACKGROUND: The purpose of this study was to estimate the economical impacts of surgical site infection (SSI) after general surgeries. METHODS: A prospective study was performed with the surgeries from September to December, 2002 and the SSI cases were collected based on the definitions of Centers for Disease Control and Prevention, The length of stay (LOS) and the hospital charge for the SSI group were compared with the non-SSI (NSSI) group by a matched cohort study for age, sex, operation procedure, and NNIS risk groups. RESULTS: There were 1,007 cases of surgeries and the 52 cases of SSI and the 26 cases have been matched. The LOS of the SSI group was 5.2 days longer than that of the NSSI group (P<0.05) which was significant, The injection and dressing meal, and total hospital charge were \157,562, \72,251, and \2,153,964 more in SSI group than those of NSSI group (P<0,05) for post-operation stay. The charge of medication and room in SSI group were \558,146 and \723,114 more than those of the NSSI group, but there were no significant difference. CONCLUSION: The SSI could increase the LOS and the hospital charge; therefore, this economic loss had an impact on the hospitals as well as the patients. To estimate the economic impacts of SSI precisely, however, further studies are needed to analyze and control other factors for the cost such as a type of surgery. In addition, the scope and setting of cost analysis should be expanded into the aspects of an individual, the hospital, and society.

OBJECTIVE: The objective is to describe the relationship of anatomical landmark required for the middle fossa approach to preservation of hearing. METHODS: Dissection of 16 fixed human cadaveric heads was performed. we identified a rhomboid-shaped middle fossa landmarks that serve as a guide to minimize cochlea injury. The points of this construct are as follows ; 1) the junction of the greater superficial petrosal nerve and the trigeminal nerve ; 2) the lateral edge of the porus trigemius ; 3) the intersection of the petrous ridge and arcuate eminence ; and 4) the intersection of the lines extended along the axes of the greater superficial petrosal nerve and arcuate eminence. Mean, minimum, and maximum measurements of all distances were determined. RESULTS: The average cochlea-geniculate ganglion distance measured in the dissected specimens was 3.0+/-0.8mm with a range of 1.2 to 4.1mm. The average cochlea-petrous carotid genu distance was 2.9+/-0.9mm with a range of 1.2 to 4.0mm. The average cochlea-internal acoustic meatus distance measured in the dissected specimens was 9.0+/-0.5mm with a range of 7.8-10.9mm. The average cochlea-mandibular nerve distance measured was 9.4+/-0.4mm with a range of 7.6-11.3mm. CONCLUSION: The middle fossa approach requires special knowledge of the anantomy to reduce the risk of damage to cochlea. It is important that the surgeon understand the surgical anantomy. The present study describes the simple geometric construct that proposes to assist in locating the cochlea.

BACKGROUND: The purpose of this study was to compare a 1% chlorhexidine gluconate/6l% ethanol (CHG/Ethanol) emollient and 7.5% povidone-iodine (PVI) scrub for antibacterial efficacy and effect on skin condition. METHODS: Twelve healthy newly employed nurses were recruited for this clinical study to evaluate the two hand cleansing agents. The CHG/Ethanol emollient hand preparation was applied without scrubbing and 7.5% PVI was applied using a scrub brush in 5-minute surgical scrubbing. Subjects used one method for 5 days and switched to the other method for another 5 days. Samples were taken for bacterial counts using the glove juice technique before and one minute after hand cleansing and again at the end of surgical operation on Day 1, 2, and 5. The VSS (Visual Scoring of Skin condition) scores and HSA (Hand Subject Assessment) scales were used to evaluate skin condition. RESULTS: Log reduction in bacterial counts by CHG/Ethanol emollient was greater than by PVI immediately after hand cleasing (log3.73 vs log1.66) and at the end of surgical operation (log3.49 vs log1.93) on Day 1. But there were no significant difference on Day 2 and 5. CHG/Ethanol emollient caused fewer skin problems than PVI; the VSS scores of the CHG/Ethanol emollient were better than those of PVI on Day 2, 3, 4, and 5 (P<0.05), and also HSA scale for change from baseline to the end of Day 5 was significantly better for the CHG/Ethanol emollient (22.5-->24.5 vs 23.0-->19.3). CONCLUSION: Compared to PVI, the CHG/Ethanol emollient hand preparation was shown to be more antibacterial and less irritation to skin. The results showed the possibility of using the waterless, scrubless agent for surgical hand scrub in Korea.

PURPOSE: Accurate diagnosis of group A streptococcal(GAS) pharyngitis and appropriate antimicrobial therapy are important, particularly to prevent nonsuppurative sequelae and to reduce the improper use of antibiotics. Because the clinical presentation of pharyngitis does not reliably predict the etiologic agent, when GAS infection is suspected, diagnosis should be based on the result of a throat swab culture or antigen-detection test with culture back-up. METHODS: We reviewed retrospectively the medical records of children diagnosed as GAS pharyngitis by throat swab culture from Jan. 1995 to Jul. 2000. Since Nov. 1998, specimens were also tested with the Abbott's Testpack+plus Strep A Kit. RESULTS: 121 patients were confirmed as GAS pharyngitis by throat culture. GAS pharyngitis predominantly occurred from 3 to 7 years of age with the peak incidence at 4 and 5 years of age. The disease was more frequent in late fall, winter and spring. Clinical manifestations were as follows; fever(89.9%), abnormal pharynx(94.3%), of which exudate in 33.6%, sore throat(85.3%), headache(78.1%), cervical lymphadenopathy(67.5%), abdominal pain(64.3%), and nausea or vomiting (55.0%). The sensitivity and specificity of rapid antigen test compared to throat culture were 96.4% and 95%, respectively. CONCLUSION: GAS pharyngitis occurred every year, and more frequently in late fall, winter and spring. It occurred with the greatest frequency in preschool children. The rapid antigen test can be a basis for clinicians to decide how to treat their patients before the culture results are proven, and can be helpful to judicious use of antibiotics as well.
