Despite continually improving results of total hip arthroplasty, infection remains the major debilitating complication. The treatments of infected total hip arthroplasty were variable. but initially we removed infected implants and inserted antibiotic containing cemented spacer so called PRSTALAC to prevent scar contracture and disuse osteoporosis. After 6 weeks later, control of infection was clinically and radiologically determined, we inserted new prosthesis with cement. Three weeks postoperatively, patient began touch down standing exercise. We observed infected total hip patient in whom hip had been salvaged successfuily with twostage implantation using so called "" PROSTALAC "" which was made with Moore stem.

An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine checkup on a 34 year-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to the list of benign connective tissue tumor of the pancreas.

This study aimed to assess the sustainability of antibacterial agents mixed with experimental fluoride varnish (EFV) against S. mutans. Five antibacterial agents [Xanthorrhizol (XAN), Bakuchiol (BAK), Bavachalcone (BCC), Isobavachromene (IBC), and Bavachromene (BCM)] were used and incorporated into the EFV to make the final concentration of 10 mM. Then, 5 μL of antibacterial agents mixed with EFV were applied on polyethylene terephthalate film disc (5 mm diameter). The positive and vehicle control were ampicillin and DMSO mixed with EFV, respectively. Each group was stored in distilled water in a 37℃ shaking water bath at 80 rpm for 0 hour, 4 hours, 1 day, 2 days, 3 days, 5 days, 10 days, 20 days and 30 days. The sustainability of the antibacterial activities was evaluated with the inhibition zone by the agar diffusion test. The antibacterial activities of all antibacterial agents were sustained for 30 days. Among them, BCC showed relatively higher antibacterial activities up to 30 days compared to other groups. This study suggests that antibacterial agents including BCC can be used with fluoride varnish to have sustained antibacterial activities.

Many patients,especially in certain high risk groups, undergo operative procedures under regional anesthesia in belief that this approach is safer than general anesthesia. During the regional anesthesia, sedation is often provided with intravenous agents, such as diazepam even if diazepam has some dipressant effects on respiration and hemodynamics. To evaluate the effects of diazepam on spinal anesthesia, arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), arterial oxygen saturation (SaO2) and mean arterial pressure (MAP) were measured at 1,3,5.10,15,20and 30min. following diazepam iv (0.2 mg/kg) under spinal anesthesia (group 2), and were compared with the changes in the control group (group 1), who received spinal anesthesia without diazepam administration. The results were as follows: 1) MAP revealed no significant decrease in the control group, and decreased significantly in the group 2 from 3 to 30 min. after diazepam iv under spinal anesthesia. 2) PaO2 did not change significantly in the control group, but PaO2 in group 2 decreased significantly at 1 and 10 min. after intravenous administration of diazepam. And the changes from 3 to 20 min. after intravenous administration of diazepom were significantly different from changes in the group 3) PaO2 increased significantly in grorp 2 from 3 min. after diazepam iv which were significantly different from the changes in the control group. 4) SaO2 decreased significantly in group 2 from 1 to 30 min. after diazepam iv which were significantly different from the changes in the control group. From the above results, diazepam administration under spinal anesthesia affects the respiratory function and hemodynamics, so oxygen inhalation technique may be needed in most cases of sedatives administration after spinal anesthesia.

Peutz-Jeghers syndrome(PJS) is a relatively rare autosomal-dominant disease characterized by the occurrence of extensive mucocutaneous hyperpigmentation and gastrointestinal polyps. PJS patients are considered to have a high prevalence of intussusception due to polyps. We report the radiological findings in two cases of intussusception due to polyps in patients with PJS, and review the literature.

Pheochromocytoma is a rare endocrine tumor arising from the chromaffin tissue, and it is able to produce and secrete catecholamines. Lymph nodes, liver, lung and bone are the most frequent sites of metastasis. We report here on a case of pheochromocytoma arising from the dura in a patient who was surgically treated for bilateral pheochromocytoma five years previously.

Recently apoptotic cell death has been reported in differentiated skeletal muscle, where apoptosis was generally assumed not to occur. To investigate whether apoptosis may contribute to the steroid-induced myopathy, rats treated with triamcinolone acetonide (TA) for 9 days were sacrificed for detecting apoptosis by in situ end labeling (ISEL) and electron microscopy in the soleus muscles. Immunohistochemical stainings of Fas antigen and p53 protein were performed to examine whether apoptosis-related proteins were present in the myopathy. Muscle fiber necrosis and apoptotic myonuclei appeared in the soleus muscles following administration of TA, while control muscles showed no evidences for apoptosis. Fas antigen was not detected in control muscles, but expressed in the soleus muscles of steroid-induced myopathy. Some of the Fas antigen-expressing muscle fibers were positive for ISEL. p53 protein was not detected in any muscle fibers. These findings indicate that TA can induce apoptosis in differentiated skeletal muscles, and Fas antigen might be partly related to apoptotic muscle death in steroid-induced myopathy.

The purpose of this study was to evaluate the growth pattern of nasopharyx and adenoid and to obtain useful measurements for evaluating the fuction of the nasal breathing. The biennial serial cephalometric radiographs of 33 samples(19 male, 14 female) with normal occlusion from 8.5 years to 18.5 years of age were used in this study. The distances, areas and ratios on nasopharynx and adenoid were measured and analyzed in each age and sex. The results of this study might be summarized as follows; 1. The mean value and standard deviation of each measurement was obtained in each age and sex. 2. The nasopharyngeal height and the nasopharyngeal depth increased significantly by 14.5 years of age in male and 12.5 years of age in female(p<0.05). 3. The relative nasal airway area showed the minimal value at 8.5 years of age and showed significant increase from 10.5 years to 12.5 years of age in male and from 12.5 years to 14.5 years of age in female(p<0.05). 4. In the correlation analysis between the measurements on the nasal airway and the measurement of relative nasal airway area, the measurements of Ad2-PNS, Ad2-PNS/Ho'-PNS and Upper pharynx appeared singnificant correlation with the measurement of relative nasal airway area(p<0.01).
