The purpose of this report is to suggest clinical managements of implant periapical lesions by presenting three clinical cases managed by either the infected form or the inactive form with the follow-up period of five to twelve years. One patient with no clinical symptom was regarded as inactive form. Two patients having pain were regarded as infected form and have been under the systemic antibiotic therapy. In one patient, the symptom subsided and the size of radiolucent lesion decreased. However, the other patient showed increased size of lesion causing the implant unstable, which leaded to remove the implant and to replace it. There was neither additional increase of the lesion nor functional problem for all three. It is important to detect implant periapical lesion in early stage before jeopardizing the stable implant and manage properly using systemic antibiotic therapy and surgical approach if needed, depending on infected form and inactive form.

We investigated the eradication rate and the adverse effects of combined treatment with western and oriental medication on Helicobacter pylori infected patients. We studied the eradication rate and the adverse effects of 1-week-triple therapy and 2-week-oriental medication(Banhasasimtang or Hyangsapeungeuysan) on Helicobacter pylori infected patients confirmed by urea breath test. Comparing 5 patients who took combined treatment with western and oriental medication, the results of this study showed that 4 patients got eradication effect of Helicobacter pylori with no influence on liver and kidney function. A patient had diarrhea and another patient had satiety after meals because of an adverse effect. Despite some possitive effect, the treatment did not make the Quality of Life improved. The findings of this study supports the adverse effects of combined treatment with western and oriental medication for the treatment of Helicobacter pylori infection.

Purpose: Despite the increasing number of patients with HIV (human immunodeficiency virus) infection, surgical experience with these patients remains limited in aesthetic and reconstructive surgery. The authors performed breast reconsruction with free TRAM (Transverse Rectus Abdominis Muculocutaneous) flap in HIV infected patient firstly in Korea. Methods: A 53-years-old female with HIV positive underwent delayed breast reconstruction with free TRAM flap and 6 months lateral nipple reconstruction was performed. All procedures were performed according to the HIV infection control guidelines provided by the Korea Centers for Disease Control and Prevention. Results: There were no complications such as infection, hematoma and flap loss and symmetry of breast was achieved. Conclusion: When the operation is performed in line with the guidelines of HIV infection control, breast reconstruction with free flap is possible and can obtain successful results.

Congenital absent sternum is a rare birth defect that requires early intervention for optimal long-term outcomes. Descriptions of the repair of absent sternum are limited to case reports, and no preferred method for management has been described. Herein, we describe the use of porcine acellular dermal matrix to reconstruct the sternum of an infant with sternal infection following attempted repair using synthetic mesh. The patient was a full-term male with trisomy 21, agenesis of corpus callosum, ventricular septal defect, patent ductus arteriosus, right-sided aortic arch, and congenital absence of sternum with no sternal bars. Following removal of the infected synthetic mesh, negative pressure wound therapy with instillation was used to manage the open wound and provide direct antibiotic therapy. When blood C-reactive protein levels declined to ${\leq}2mg/L$, the sternum was reconstructed using porcine acellular dermal matrix. At 21 months postoperative, the patient demonstrated no respiratory issues. Physical examination and computed tomography imaging identified good approximation of the clavicular heads and sternal cleft and forward curvature of the ribs. This case illustrates the benefits of negative pressure wound therapy and acellular dermal matrix for the reconstruction of absent sternum in the context of infected sternal surgical site previously repaired with synthetic mesh.

The purpose of these experiments is often to scan infected patients with MRI. Therefore, it is to investigate whether the antibacterial film containing silver ions, which is a non-magnetic substance, affects magnetic resonance imaging. In this experiment, the ACR phantom was used, not the patient. The ACR phantom was wrapped in an antibacterial film and the SNR, CNR, sagittal localization image, and geometrical accuracy were compared before and after. The experiment was performed 10 times and the averaged values were compared. There were no significant differences in the results of all experiments. The FDA recommends removing metal and antibacterial film masks during MRI scans. The reason is that there was one case of injury with facial burns. When I touched the antibacterial film to check the fever during the 2 hour experiment, I did not feel any particular fever. In light of the experimental results, it would be helpful to use an antibacterial film when testing an infected patient. The reason is that there isn't a difference before and after the experiment of SNR, CNR, and sagittal localization images.

One hundred and thirteen healed pulmonary tuberculosis patients and 11 patients with other underlying diseases were studied for evidence of pulmonary fungal infection because of persisting hemoptysis or chronic cough. Rediological, mycological and serological investigations revealed that 54 out of 124 patients were evidently infected with one or more species of fungi. A. fumigatus was isolated from 4 out of 70 patients whose sera did not react with antigens from this fungus, while it was isolated from 43 out of 47 serological reactors to this fungus. Chest radiography showed a distinct fungus ball in a cyst of one patient and in a preformed cavity in the lung of 17 healed tuberculosis patients and two other patients. The latter two patients were infected with A.flavus. Two patients, who were under the long period of immunosuppressive therapy, apparently succumbed to invasive aspergillosia due to A.fumigatus. A single or dual infection with A. flavus, A. nidulans, A.nidulans var. latus, C. albicans, and P. boydii were noticed in some patients without mycetomal shadow on chest radiographs. Young mycelial extract (ME) of A.fumigatus detected antibody in 95.8 percent of the sera from patients infected with this fungus, while it was isolated from 43 out of 47 serological reactors to this fungus. Chest radiography showed a distinct fungus ball in a cyst of one patient and in a performed cavity in the lung of 17 healed tuberculosis patients and two other patients. The latter two patients were infected with A. flavus. Two patients, who were under the long period of immunosuppressive therapy, apparently succumbed to invasive aspergillosis due to A.fumigatus. A single or dual infection with A. flavus, A. nidulans, A. niduans var. latus, C. albicans, and P. boydii were noticed in some patients without mycetomal shadow on chest radiographs. Young mycelial extract (ME) of A.fumigatus detected antibody in 95.8 percent of the sera from patients infected with this fungus, while the commercial culture filtrate antigen (GL) yielded 78.7 per cent positive result. Culture filtrate antigen, however, was comparable with ME. There was no single antigen with which all the serum specimens reacted. Fractionation of ME resulted in a loss of some activity although it excluded substances that reacted with C-reactive protein in a loss of some activity although it excluded substances that reacted with C-reactive protein. Most reactive and specific precipitinogens distributed in the fraction (FB) which was precipitable at 75 percent saturation with ammonium sulfate and eluted in a second peak in order from gel-filtration and which contained mostly proteinic components. Glycoproteins or polysaccharides rich fractions (FA and ASI) were relatively less effective in detecting antibody. Demonstration of antibody in the serum from patients using a battery of fungal antigens and of etiologically related fungi from clinical specimens are very useful laboratory procedures for the diagnosis of pulmonary fungal infection which is a common complication of tuberculosis.

Purpose: Infection with HIV-1 virus has become a critical worldwide public health problem. The oral complications of HIV infection with its progression of impairment of the host response to combat infection present unique challenges to the periodontists. Material and Methods : Medline research was carried out to find relationship of the progression of HIV infection to the occurrence of oral lesions including the HIV-related periodontal diseases. Results: The linear gingival erythema, necrotizing ulcerative periodontitis, necrotizing ulcerative gingivitis and oral candidiasis are common lesions in HIV-infected individuals. The linear gingival erythema and necrotizing ulcerative periodontitis lesions in HIV-infected subjects were found to have a similar microbiological profile. There are several general considerations in the periodontal management of the HIV-infected patient with or without periodontal disease. The altered immunity and host response in patients with HIV infection may also affect the incidence and severity of other common forms of periodontal disease not associated with HIV infection. Conclusion: Periodontal diseases in HIV-infected individuals present unique challenges in diagnosis, monitoring, treatment and maintenance. Therefore exact HIV staging, geographic location, antiviral and antimicrobial therapies and oral habits should be taken into consideration when treating HIV-infected patients.

In the diagnosis of parasitic helminthic diseases, the value of examining and identifying the parasitic eggs and/or adult parasites from patient's urine or stool are well appreciated. However, these methods have a limited value in the diagnosis of tissue or intracellular parasitism, and we have to rely on supplementary methods such as immune-serological test. The author tested the value of gel precipitation reactions as a diagnostic method of clonorchiasis by observing the appearance of bands in rats experimentally infected with Clonorchis sinensis, And the therapeutic effect of CIBA 35'058-Ba was evaluated by this serological method. The antigen was prepared from the adult worms infected in rabbits by Tsuji method. Rats infected with 40 metacercariae each were bled on 7,14,21,26,28,39,42(43),49(53) days after infection to observe the appearance of precipitin bands by both Oucterlony method and immunoelectrophoresis. Fifteen rats were separately infected and treated with CIBA 35'058-Ba in dose of 15mg/kg of body weight. The following results were obtained: 1. It was observed that there exist individual variations in the appearance of the first precipitin band with the range of 2-4 weeks after infection. 2. The number of precipitin bands was increased until 6-7 weeks after infection. In all cases, 3 precipitin bands were appeared by Oucterlony method and 6-7 bands were appeared by immunoelectrophoresis after 6-7 weeks of infecion. 3. It was hardly possible to notice any change in the number of bands after the administration of CIBA 35'058-Ba. This result suggested that the drug has no effect on clonorchiasis which was confirmed by the autopsy of the experimental rats.

Aortic aneurysms infected by Klebsiella pneumoniae are rarely seen. We describe a 50-year-old man with infected aortic aneurysm that was successfully treated with endovascular aneurysm repair (EVAR). Diagnosis was confirmed using blood culture and computed tomography (CT). Intravenous antibiotics were immediately administered, with improvements in clinical findings and negative blood cultures before the procedure. Twenty-four months after the procedure, the patient was stable and serial CT revealed regression of the infected aortic aneurysm. Therefore, after controlling bacteremia and fever with targeted antibiotic therapy, EVAR can be considered as an alternative for patients who have serious comorbidities and are ineligible for conventional surgery.

Failure to use effective methods of reduction, fixation, and immobilization may lead to nonunion with osteomyelitis, owing to the compound nature of most fractures of the mandible. Nonunion results in fibrous pseudoarthrosis at the fracture site with instability that, once formed, does not improve spontaneously. Once the nonunion with osteomyelitis secondary to fractures has become established, intermaxillary fixation and drainage of infected tissue should be instituted as early as possible, because the fixation & drainage enhances the patient comfort and hinders ingress of microorganisms & debris by movement of bone fragments. The authors treated three cases of nonunion with osteomyelitis by intermaxillary fixation, incision & persistent drainage on the previous fistula site and endodontic drainage of infected teeth in the fracture site of mandible. The localization & sequestration of the infected bone around the fracture was better performed persistently by natural homeostatic mechanism in $8{\sim}10$ weeks and the bony union was then attained without bone grafting.
