Purpose : Lymphadenitis is the most common complication of BCG vaccination and has various clinical course and prognosis, but there are no accurate guidelines for management of BCG lymphadenitis. We performed this study to reveal the clinical course of BCG lymphadenitis and provide guidelines for its management. Methods : From January, 1997, to May, 2000, 73 patients in the 3~24 months were enrolled. We investigated retrospectively the size, site, and number of lymphadenitis, tuberculin skin test induration, used BCG strains, vaccination age, injection site, treatment and clinical course. The effects of various variables on clinical course were evaluated. Results : 1) There were no statistically significant difference between lymphadenitis size and tuberculin test induration diameter, spontaneous resolution rate, and suppuration rate. 2) Later vaccination(${\geq}1$ mo) and supraclavicular lymphadenitis increased suppuration rate. Using domestic BCG product increased surgical treatment rate. 3) According to treatment(observation vs antituberculous medication), medication did not affect the prevention of suppuration and ironically increased the rate of suppuration and surgical treatment. 4) Suppurative lymphadenitis required more surgical treatment than non-supurative one. Conclusions : Clinical course of BCG lymphadenitis is affected by vaccination age, used BCG strains, site of lymphadenitis, antituberculous medication and suppuration, but not affected by size and number of lymphadenitis. For management of BCG lymphadenitis, systemic antituberculous medicaion is not recommended and regular follow up with observation should be the mainstay. But for suppuration, active surgical en bloc resection should be the treatment of choice.

Purulent pericarditis is defined as a localized pericardial infection with gross pus formation in the pericardial space. Although purulent pericarditis is now rare in the antibiotic era, it may be life-threatening. We describe a rare case of purulent pericarditis that originated from a subdiaphragmatic suppurative focus in an immunocompromised host.

Porphyromon as endodontalis, a gram-negative anaerobic rod, is an important pathogenic organism in periapical lesionis with acute symptoms, such as pain, swelling, and suppuration in endodontic patient. Like P. gingivalis, a major pathogen of adult periodontitis, P. endodontalis is asaccharolytic and forms black-pigmented colonies on enriched blood agar plates. However, the pathogenic factors and the pathological potential of this microbe have been poorly characterized.(omitted)

This study was undertaken to evaluate the pulpal responses to the pulp-capping materials such as glutaraldehyde and formocresol in pulpotomy technique, especially in the primary dentition. Mandibular primary canines and molars of 5 dogs (aged about 8-9 weeks)were selected for this study. The intervals of observation for histologic study of pulpotomized primary teeth with 2% glutaraldehyde, formocresol and calcium hydroxide in the usual manner ranged from 2 hours, 1 week, 2 weeks, 3 weeks and 5 weeks after experiments respectively. Each specimens were fixed with 10% formalin and decalcified in 5% nitric acid. All slides were stained with Hematorylin-Eosin and examined histopathologically. The results were as follows; 1. In calcium hydroxide groups, formation of dentin bridge was initiated in 1 week after experiments and completed in 5 weeks after experiments. 2. Formation of dentin bridge was not seen, whereas necrosis of pulp tissue was noted, in formocresol and glutaraldehyde groups. 3. Duration of tissue reactions and tissue changes were similar, in formocresol and glutaraldehyde groups. 4. In formocresol and glutaraldehyde groups, amputation surfaces of the pulp were covered with blood clots, beneath which coagulation necrois was noted, but inflammatory cells were not prominent, in 2 hours and 1 week after experiments. But coagulation necrosis was proceeded to the apical portion, accompanied by infiltration of inflammatory cells, since 2 weeks after experiments. And suppuration or gangrene of the pulp tissue were noted in 3 weeks and 5 weeks groups. 5. Suppuration or gangrene of pulp seemed to provoke the resorption of dentin wall, and inflammatory changes and resorption of roots were noted in the periodontal membrane near the periapical region. 6. As compared with calcium hydroxide groups, resorption of the root was pronounced in form or cresol and glutaraldehyde groups. Effects of medicaments to the succedaneous tooth germ were not seen.

Purpose: This study aimed to evaluate the usefulness of the needle aspiration alternative to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage. Methods: From January 1998 to June 2008, we retrospectively reviewed 38 children treated with needle aspiration as management with suppurative cervical lymphadenitis instead of open surgical drainage. Results: All 38 children underwent only 1 puncture. Two patients (5.2%) out of 38 patients experienced reformation of an abscess and all recovered completely after re-treatment with antibiotics. Minor complications were detected in 2 patients (5.2%). One complication originated from remnant necrotic tissue and the other involved formation of a small scar in two patients, which resolved spontaneously. There were no major complications. Conclusion: Needle aspiration can be a simple, safe, and effective alternative procedure to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage.

Pulmonary actinomycosis is a chronic pulmonary infection characterized by suppuration, abscess formation, and dense scarring. The causative agent, Actinomyces israelii, is a gram-positive, microaerophilic bacterium that resemble fungi. We recently treated two cases of pulmonary actinomycosis. A patient was underwent right lower lobectomy under the impression of bronchiectasis. Pulmonary actinomycosis was diagnosed of postoperatively. He was medicated with high-dose penicillin parenterally. The other patient was also undergone right lower lobectomy under the impression of broncholithiasis and received parenteral penicillin and oral roxythromycin. There was no recurrence or development of empyema. The purpose of this paper is to review of our experience and to enhance consideration of pulmonary actinomycosis.

This article presents the case of a bilateral chronic subdural hematoma which was contaminated with Klebsiella pneumoniae and resulted in a life-threatening central nervous system infection. After repeated of bilateral burr-hole drainage, the patient became hyperpyrexic and drowsy. Suppuration within the subdural space was suspected and then the patient underwent bilateral fronto-temporo-parietal craniotomies, and pus was evacuated. Its cultures revealed Klebsiella pneumoniae. Intravenous meropenem was given for 6 weeks. He recovered completely. Microorganisms like Klebsiella pneumoniae may directly infect the subdural space with iatrogenic contamination.

Peri-implant diseases are inflammatory lesions, which include peri-implant mucositis and peri-implantitis. Peri-implant mucositis is described as the presence of inflammation in the mucosa around implants without any bone loss. By contrast, in peri-implantitis, besides the inflammation in the peri-implant mucosa, loss of supporting bone is also seen. Diagnosis of peri-implant diseases require the use of gentle probing(0.2 ~ 0.3N) to identify the presence of bleeding on probing, probing depth and suppuration, both signs of clinical inflammation. Radiographs are required to detect loss of supporting bone. Baseline probing measurements and high quality, long cone periapical radiographs should be obtained once the restoration of the implant is completed to make possible longitudinal monitoring of peri-implant tissue.

Purpose : A regional lymphadenitis is the most frequent adverse reaction of BCG. In order to find out developmental factors and establish a strategy of management, we investigated the clinical courses of children with lymphadenitis following BCG on the aspect of BCG strains, suppurative rates according to the sizes of lymph node and the clinical difference with or without treatment. Methods : From January 1997 to June 2004, 52 children less than 24 month-age-old diagnosed as BCG lymphadenitis in Department of Pediatrics, St. Vincent's Hospital, The Catholic University of Korea were enrolled. The type of BCG strain, place of vaccination, location and size of lymphadenitis were assessed with medical records, retrospectively. Finally, we analysed the correlations between BCG strains or the sizes of lymph node and natural remission or suppuration. Results : The first detected mean age of BCG lymphadenitis was 5.5 month-age. The larger of the measurement was at the first visiting, the younger of age that was first presented. The most frequent location was the same sided axillary region of BCG injection. Among 52 subjects, 46 cases(88.5%) were vaccinated with intradermal Pastuer strain, and only 5 cases(9.6%) were done with percutaneous multipunctured Tokyo strain. Twenty eight cases(53.8%) were regressed naturally, otherwise 24 cases(46.2%) were suppurated. The larger those were sized, the higher freqeuncies those were suppurated on, significantly. Treatment with medications could not prevent the suppuration and could not shorten the healing periods. Conclusion : We predict that there are differences between the occurrent rate of BCG lymphadenitis and BCG strains or methods. Treatment with medication is not recommended owing to its ineffectiveness. Especially, in case of non-suppurative lymphadenitis should be onlyless influence on the tuberculin skin test, cause less adverse reactions, and is inexpensive. observed without treatment, because it could be regressed naturally. An ideal BCG makes a scar, We should make an effort to choose the best BCG strain that can fulfill such requirements.
