PURPOSE: To compare the results of posterior cruciate ligament reconstruction by open and arthroscopic method. MATERIALS AND METHODS: From 1995 to 1997, 18 reconstructions of posterior cruciate ligament were performed. Group 1 (open method) was composed of 9 cases and group 2 (arthroscopic method) was consisted of 9 cases. After 21-month follow-up, The two groups were compared by clinical and radiologic methods. RESULTS: Clinically, Lysholm knee score was 80 points in group 1 and 83 points in group 2 after operation. Post operative results by Hughston's criteria were good in 5, fair in 2 and poor in 2 cases (group 1) and good in 6, fair in 2 and poor in 1 cases (group 2). Radiologically, post operative average of posterior drawer stress view was 5.2 mm (group 1) and 5.0 mm (group 2). Almost double the operation time was taken to reconstruct posterior cruciate ligament by arthroscopic method than open method. There were technical errors in 2 cases performed by arthroscopic method. CONCLUSIONS: The results of both methods had no significant difference. We think that the reconstruction of PCL using patellar tendon by open method is a recommendable treatment method together with arthroscopic method, if the merits or demerits of both methods are considered carefully. But more long-term follow-up is necessary to compare the results of PCL reconstruction by open and arthroscopic methods.

While the microbiology of cellulitis in the pediatric population and systemic diseases(DM, Cirrhosis, etc) is well known,the causative bacteria and clinical aspect of cellulitis in young adults are less descrihed. this study was undertaken to identify the causative organisms and clinical aspect of adult cellulits. We analysed 121 medical records of 115 young adult patients with cellulitis who had been admitted at the department of orthopaedic surgery, National Police hospital from Jan. 1994. to Dec. 1996. The results were as follows. 1. The age of patient was between 21 yrs and 25 yrs, and the sex of all patients was male. 2. The lower leg and foot were the most frequently involved site of cellulitis as 92 cases(74.2%). 3. The potals were suspected in 65 cases(56.5%),of them, traumas were detected in 43 cases(66.1%), non-traumatic skin lesions in 23 cases(33.9%). 4. In most cases, initial systemic symptoms (fever, chill, headache, etc.) and local symptoms (local heating, tenderness, etc.) were found. 5. The laboratory findings revealed leukocytosis in 19%, elevated ESR in 94%, positive CRP in 80%. 6. Microorganism were detected in 16 of 38 pus cultures. Gram positive microorganisms were detected in 15 of 16 cases culture positive. 7. 6.7% of patients with cellulitis experienced recurrence in same lesions. In conclusion, the retrospective analysis of 115 young adult patients with cellulitis showed that primary cause of young adult cellulit was circulatory disturbance and lymphatic obstruction of the lower extremities most often involved by trauma. therefore, supportive treatments such as rest,elevation,ice packs are considered prior to antibiotic treatment.antibiotic treatment aimed at gram-positive cocci appears to be sufficient.

In order to study the change in bacterial population, the effect of immunity on bacteriuria, and the antibody response in urinary tract infections. Escherichia coli 06(06) was inoculated in bladder and kidney of rabbits non-immunized and immunized with 0 antigen of 06 and enterobacterial common. antigen(CA) of Kunin derived from culture supernatant of Salmonella typhimurium. The results obtained are as follow: 1. Rabbits immunized with O6 antigen and CA showed high antibody titers in sera, and tires were usually higher in rabbits immunized with 06 antigen than those with CA. 2. Bacterial counts reached highest number at the first day of observation in urine of rabbits inoculated in bladder, and after 3 days in rabbits inoculated in kidney. Numbers of bacteria decreased gradually after the highest: peak of bacterial counts, but still remained at considerable numbers after 13~l6 days of inoculation. There were no significant differences in bacterial counts between immunized and non-immunized rabbits. 3. Among non-immunized rabbits, antibody titer began to rise from 4th to 7th days of inoculation in bladder, and from 4th day of inoculation :in kidney. Titers were very low in groups inoculated in bladder, and significantly high in rabbits inoculated in kidney. Antibody titers were usually high when large size of inoculum was used 4. Antibody titers decreased ;gradually and slightly when 06- or CA-immunized rabbits were inoculated with 06. 5. Rabbits inoculated 06 into kidney showed considerable increase in antibody titers from 4 to l0days after inoculation in CA. immunized rabbits, while gradual decrease from the beginning of inoculation in those inoculated in bladder. 6. There were no significant changes other than chronic inflammation in kidneys of rabbits inoculated with 06 in kidney of immunized and non-immunized rabbits when observed after about two weeks of inoculation, No significant difference by the size of inoculum was also observed.

Bronchial carcinoid tumor was a low grade malignant and it was regarded as predictable clinical course and good survivality after surgical resection. But despite of its low grade malignant potentiality, bronchial carcinoid tumor was clearly capable of metastasizing and causing death. We present 2 cases of bronchial carcinoid tumors. One of them was typical carcinoid tumor in 44 year-old female and another was atypical carcinoid tumor in 53 year-old male patient. Currative therapeutic procedure was performed by lobectomy and wedge resection.

PURPOSE: In this study, we developed a new software tool for the analysis of renal scintigraphy which can be modified more easily by a user who needs to study new clinical applications, and the appropriateness of the results from our program was studied. MATERIALS AND METHODS: The analysis tool was programmed with IDL5.2 and designed for use on a personal computer running Windows. For testing the developed tool and studying the appropriateness of the calculated glomerular filtration rate (GFR), 99mTc-DTPA was administered to 10 adults in normal condition. In order to study the appropriateness of the calculated mean transit time (MTT), 99mTc-DTPA and 99mTc-MAG3 were administered to 11 adults in normal condition and 22 kidneys were analyzed. All the images were acquired with ORBITOR, the Siemens gamma camera. RESULTS: With the developed tool, we could show dynamic renal images and time activity curve (TAC) in each ROI and calculate clinical parameters of renal function. The results calculated by the developed tool were not different statistically from the results obtained by the Siemens application program (Tmax: p=0.68, Relative Renal Function: p=1.0, GFR: p=0.25) and the developed program proved reasonable. The MTT calculation tool proved to be reasonable by the evaluation of the influence of hydration status on MTT. CONCLUSION: We have obtained reasonable clinical parameters for the evaluation of renal function with the software tool developed in this study. The developed tool could prove more practical than conventional, commercial programs.

Central neurogenic hyperventilation (CNH) is characterized by sustained tachypnea inspite of an elevated arterial PaO2, pH and a low arterial PaCO2. CNH is common in patients with brainstem injury accompanied by a decreased level of consciousness but this also has been described in some alert patients with an invasive brainstem tumor. We report one case with CNH resulting from a unilateral pontine infarction. His consciousness was clear, and CNH spontaneously disappeared without any medication.

BACKGROUND: Hemodynamic evaluation of the brain may be helpful for the identification of a risk of stroke in patients with middle cerebral artery (MCA) or internal carotid artery (ICA) steno-occlusive disease. The aim of this study was to evaluate the hemodynamic state in patients with steno-occlusive disease of ICA or MCA on the base of MRI/MRA and acetazolamide (ACZ)-challenged Tc-99m ECD brain perfusion SPECT findings. METHODS: An analysis of 68 patients who underwent MRI/MRA and ACZ-challenged Tc-99m ECD brain perfusion SPECT was performed. We divided these patients into two groups - MCA and ICA steno-occlusions. RESULTS: The cerebrovascular reserve (CVR) was impaired in 18 of 32 (56.3%) MCA disease patients (20 stenosis and 12 occlusions), and in 19 of 36 (52.8%) ICA disease patients (20 stenosis and 16 occlusion). The CVR was impaired in 22 of 28 (78.6%) occlusive patient, whereas in 15 of 40 (37.5%) stenotic patient (p< 0.01). The insular lesion was more commonly involved in the occlusion group (54%) than in the stenosis group (15%) (p< 0.01). CONCLUSIONS: There was no difference in CVR between MCA and ICA steno-occlusion groups. Incidence of impaired CVR was higher in occlusion group than stenosis group.
