OBJECTIVE: The purpose of this study is to evaluate the findings of magnetic resonance(MR) perfusion study and relation with the prognosis in patients of head trauma. METHODS: Forty-two consecutive patients with head trauma were evaluated and the findings of brain computed tomography(CT) and MR image were compared with MR perfusion study. We classified perfusion MR findings into 5 categories and correlated with the prognosis. RESULTS: In all 42 patients with head trauma, 38 cases(90.5%) showed new lesions of abnormal perfusion pattern in MR perfusion study compared to CT and conventional MR image. Causes of the trauma were motor vehicle accident(73.8%) falling(16.7%), and blows to the head(7.1%) in order of frequency. The cumulative prevalent sites of focal abnormalities were frontal lobe in 11 cases(39.3%), basal ganglia and thalamus 9 cases(32.1%), temporal lobe 3 cases(10.7%) and parietal lobe 3 cases(10.7%) and occipital lobe 1 case(3.6%) and cerebellum 1 case(3.6%). The pattern of abnormalities in MR perfusion study were focal type in 18 cases(42.8%), diffuse type 18 cases(42.8%), mixed type 4 cases(9.5%). MR perfusion findings showed statistically significant correlation with initial Glasgow Coma Scale score and Glasgow Outcome Scale score(p<0.05). CONCLUSION: The patterns of perfusion MR abnormality show significant correlation with the prognosis. Further study is mandatory to define the meaning of perfusion defect area and clinical significance.

OBJECTIVES: This study was performed to consider the clinical experience of an ultrasound-guided vacuum-assisted resection (Mammotome) for benign breast lesions through a core needle biopsy. METHODS: The authors carried out a core needle biopsy and Mammotome for 347 patients and investigated the pathologic results. RESULTS: The significant difference of core needle biopsy and Mammotome results was demonstrated, Spearman correlation coefficient is 0.413 in a correlation analysis. CONCLUSION: This experience suggest Mammotome is a useful procedure for providing more correct pathologic findings through complete resection of benign breast lesions.

Lower eyelid retraction is usually managed by recession of the lower lid retractors and interposition of a spacer graft including ear cartilage, nasal septal cartilage, donor sclera or autogenous tarsoconjunctiva.We have used hard palate mucosa as a spacer in 10 patients (11 eyelids)with lower lid retraction.Average age at operation was 36 years with the range of 10 years to 59 years.Causes of the lower lid retraction were thyroid ophthal-mopathy (4 eyelids), strabismus surgery (2 eyelids), entropion repair (2 eye-lids), eyelid infection (2 eyelids), and trauma (1 eyelid).Of 11 eyelids, 7 eye-lids were combined with entropion due to the shortage of posterior lamella. The follow-up period ranged from 3 to 45 months (mean 17 months).Surgi-cal results in all 11 eyelids were satisfactory.There was no complication in donor site.Hard palate closely approximates lower lid tarsus in terms of contour, thickness, and stiffness, provides a mucosal surface and shows only minimal shrinkage. We suggest hard palate mucosal grafts as one of the best available spacer material for the treatment of lower lid retraction.

BACKGROUND: Restenosis is a major limitation of balloon angioplasty. Recently, new angioplasty devices have been used in an attempt to reduce the restenosis compared with coronary balloon angioplasty. Directional coronary atherectomy effectively dilated the lesion by removal of the atherosclerotic plaque. Therefore, we tried to evaluate immediate and late clinical outcomes after directional coronary atherectomy in the 57 patients with coronary artery disease. METHODS: From October 1991 to March 1997, fifty seven consecutive patients with 69 lesions were treated with directional coronary atherectomy. The patients underwent coronary angiography at pre-intervention, immediately after intervention and at 6 months post-intervention. Restenosis was assessed clinically and by computer-assissted quantitative measurements of luminal dimensions. Patients were requested to undergo coronary angiography at 6 months after directional coronary atherectomy. Angiographic restenosis was defined as more than 50% diameter stenosis by quantitative coronary angiographic analysis. RESULTS: Successful results were achieved in 61 of the 69 lesions(88%) and mean stenosis was reduced from 78.0+/-13.0% to 10.0+/-5.0%. Atherectomy resulted in an increase in minimal lumen diameter from 0.8+/-0.3mm to 3.0+/-0.6mm. Six months follow-up angiogram was obtained in 68% of 50 eligible lesions. The overall angiographic restenosis rate was 32%. Six month clinical follow-up was obtained in 94% of the eligible lesions. The clinical recurrence occured in 38% of the patients. The target lesion revascularization rate was 17%. CONCLUSIONS: Removal of coronary artery plaque with directional atherectomy led to large luminal diameter and six months follow-up angiography shows an overall restenosis rate of 32% However, further clinical study is warranted to evaluate the efficacy of atherectomy with larger numbers of patients.

Syphilitic aortitis, passing out of our mind, is the most common systemic manifestation of late syphilis and is more typically manifestated 10 to 30 years afterward. This diagnosis has been made less frequently in recent decades than in the past, because of public awareness of syphilis and screening program. Treponema pallidum lodge within vasa vasorum, especially ascending aorta cause the histologic changes, which are responsible for the three major forms of symptomatic cardiovascular syphilis, including aortic insufficiency, coronary ostial stenosis, and aortic aneurysm. We experienced a case of syphilitic aortitis with aortic insufficiency and aortic aneurysm in a 48-year-old man presented with progressive dyspnea. Echocardiography, chest CT, and later surgical correction were performed and surgical specimen revealed the histologic finding consistent with syphilitic aortitis. We report this case with a review of the literature.

The purpose of this study was to compare the normal and two times of application time of six self-etching primers applied to enamel using microshear bond strength (uSBS) test and the finding of scanning electronic microscope (SEM). Crown of sixty human molars were bisected mesiodistally and buccal and lingual enamel of crowns were partially exposed and polished with 600 grit SiC papers. They were divided into one of two equal groups subdivided into one of six equal groups (n = 10) by self-etching primer adhesives. After the same manufacture's adhesive resin and composites were bonded on the enamel surface of each group, the bonded specimens were subjected to uSBS testing and also observed under SEM. In conclusion, generally two times of primer application time increased the enamel uSBS, especially with the statistical increase of bond strength in adhesives involving high-pH primers.

Omphalitis is an infection of the umbilicus that can cause inflammation to spread. Omphalitis is rare in adults; however, it can occasionally occur owing to urachal remnants. A 61-year-old male patient with abdominal pain and umbilical pus was admitted to the emergency room.Abdominal computed tomography revealed peritonitis with multiple intra-abdominal abscesses.The patient was diagnosed with peritonitis resulting from urachal cyst rupture. Laparoscopic drainage of the abscesses and excising of the umbilicus and intra-abdominal fistula tract were performed. Antibiotics were administered, and the patient was discharged uneventfully. The rarity of peritonitis caused by infection and urachal cyst rupture can make diagnosing omphalitis challenging. Therefore, in this case report and literature review, we discuss the diagnosis and treatment of complicated omphalitis, which rarely progresses to peritonitis owing to ruptured urachal cysts.
