The definition of anaphylaxis is 'a serious, life-threatening generalized or systemic hypersensitivity reaction' and is considered as the life threatening adverse drug reaction. We experienced a case of cefotetan induced anaphylaxis with negative pre-skin test, used for surgical prophylaxis. A 82-year-old female was scheduled for total knee replacement therapy. She had no previous history of allergy and her skin test results were also negative. On her right knee surgery, she underwent cefotetan therapy as a surgical prophylaxis for a week with no problems identified. Next left knee surgery, she also received the prophylaxis of intravenous cefotetan. However, a few minutes later, anaphylactic reaction developed with vomiting, severe hypotension, bronchospasm, and dyspnea. After immediate intensive care treatment, she recovered without significant complications. Though commonly used laboratory data in case reports, such as the specific IgE, tryptase, histamine, or allergic skin prick test were limited, we successfully confirmed anaphylaxis based on clinical criteria for diagnosing anaphylaxis based on WAO 2011 guideline with through concurrent patient°Øs medical history review and the process of identifying the causes.

The binding characteristics of five cephalosporins, cefamandole, ceftriaxone, cefoxitin, latamoxef, and cefotetan to bovine serum albumin (BSA) was examined by UV difference spectrophotometry. 2-(4'-hydroxybenzeneazo) benzoic acid was used as the spectrophotometric probe. Competitive bindings between the probe and cephalosporins were observed. Based on the Scatchard plot, the BSA appeared to have two classes of binding sites in BSA binding with cephalosporins. The number of primary binding sites appears to be one, secondary binding sites appears to be three. The binding constants were found as follows: BSA-HBAB; $K_1^{obs}$=8.39$\times$$10^4$ $M^{-1}$, $K_2^{obs}$=1.60$\times$$10^4$ $M^{-1}$, BSA-Cefamandole; $K_1^{obs}$=5.44$\times$$10^3$ $M^{-1}$, $K_2^{obs}$=0.74$\times$$10^3$ $M^{-1}$, BSA-Cefotriaxone; $K_1^{obs}$=6.78$\times$$10^3$ $M^{-1}$, $K_2^{obs}$=0.88$\times$$10^3$ $M^{-1}$, BSA-Cefoxitin; $K_1^{obs}$=7.24$\times$$10^3$ $M^{-1}$, $K_2^{obs}$=1.13$\times$$10^3$ $M^{-1}$, BSA-Latamoxef; $K_1^{obs}$=8.87$\times$$10^3$ $M^{-1}$, $K_2^{obs}$=1.92$\times$$10^3$ $M^{-1}$, BSA-Cefotetan; $K_1^{obs}$=15.41$\times$$10^3$ $M^{-1}$, $K_2^{obs}$=2.7$\times$$10^3$ $M^{-1}$.

The in vitro inactivation of gentamicin and tobramycin by four cephalosporins (cefotetan, cefuroxime, cefodizime, cefotiam) in human serum was investigated. Each cephalosporin was added to human serum samples containing gentamicin sulfate or tobramycin sulfate. Blank samples containing only aminoglycosides were used as controls. Samples were stored at -20, 4 and $25^{\circ}C$ and were analyzed for aminoglycoside concentrations by fluorescence polarization immunoassay ($TDxFLx^{TM}$ system) at 0, 2, 4, 8, 12, 24, 48 and 72 hours after mixing. The serum containing cefotiam stored at $25^{\circ}C$ showed significant inactivation of gentamicin by $12\%$ at 72 hours. The results indicate that cefotitan, cefuroxime and cefodizime do not inactivate gentamicin and tobramycin while cefotiam inactivates gentamicin.

본 연구는 2020년 5월부터 7월까지 서울시내 대형마트에서 수거한 연어 제품 65건에 대해서 리스테리아 모노사이토제네스를 분리하고, 분리한 균주에 대해서 혈청형, 병원성 관련 유전자 유무 및 항균제 내성 현황을 조사하였다. 연어 제품 65건 중에서 훈제연어 제품 53건 중 15건(28.3%), 기타 연어 제품 12건 중 1건(8.3%)에서 리스테리아 모노사이토제네스가 분리되었다. 리스테리아 모노사이토제네스 16균주의 혈청형을 분석한 결과 1/2a 형이 6균주(37.5%), 1/2b 형이 10균주(62.5%)로 1/2b 형이 우세한 것으로 확인되었다. 연어 제품의 보관방법, 제조회사 및 연어의 원산지별 혈청형과의 연관성을 살펴본 결과 냉장보관 제품에서는 1/2a 형이, 냉동제품에는 1/2b 형이 우세하였으며, 동일 제조회사 제품에서 동일한 혈청형이 확인되었고, 연어 원산지별과는 연관성이 확인되지 않아 연어 제조공정상에서 균의 오염이 주로 이루어짐을 짐작할 수 있었다. 리스테리아 모노사이토제네스의 병원성과 관련된 10가지 유전자에 대해 PCR 검사를 수행한 결과 16균주 모두 병원성 관련 유전자가 검출되어 잠재적으로 병원성이 확인되었다. 분리된 16균주에 대하여 15종의 항균제에 대한 감수성 시험을 실시한 결과 cefotetan 16주(100%), cefotaxime 14주(87.5%), cefepime 5주(31.3%), erythromycin과 tetracycline에 각각 1주(6.3%) 순으로 내성을 나타내었고, 나머지 10종의 항균제에 대해서는 모두 감수성을 나타내었다. 리스테리아 모노사이토제네스는 본질적으로 cefotetan, cefotaxime, cefepime과 같은 cephalosporine 계 항균제에 내성을 나타내는 것을 감안하면 대부분의 항균제에 감수성을 나타내는 것으로 확인되었다. 국내에서 소비가 점점 늘고 있고, 비가열 섭취가 대부분인 연어 제품에서 소비자의 안전성 확보를 위해 리스테리아 모노사이토제네스에 대한 지속적인 모니터링 및 관련 연구가 필요할 것으로 생각된다.

Purpose: This study compared the frequency of postoperative infections in patients for a closed mandibular fracture with that without the postoperative antibiotic prophylaxis. Patients and Methods: 48 patients without any specific medical history were divided into two groups depending on whether or not antibiotics had been applied after the surgery. The 24 patients in group 1 received only a second-generation cephalosporin ($Cefotetan^{(R)}$) intravenously from admission to immediate after the surgery. Likewise, 24 patients in group 2 received 1.0g of $Cefotetan^{(R)}$ twice daily longer than the third day after surgery. The mean (SD) duration of antibiotics administration after surgery was 6.9 (${\pm}3.56$). The patients were evaluated after surgery for any postoperative infections according to the criteria: purulent drainage from a wound, spontaneous wound dehiscence accompanied by swelling, pain, and fever around the wound. Results: Postoperative infections were encountered in 2 out of 24 patients in group 1, who received antibiotic medication until shortly after surgery, and in 3 out of the 24 patients in group 2, in whom the medication was continued even after the surgery. There was no sig nificant difference in the incidence of postoperative infections between the two groups. Conclusion: From this study, postoperative use of antibiotics seems to be unnecessary with view of the little significance of the factors that could affect the wound infection.

A case of recurrent urinary tract infection by cysteine-requiring Escherichia coli in a 5-years-old child with congenital vesicoureteral reflux is described. This bacterium was not grown on MacConkey agar plate for overnight culture, and after 48hrs, tiny colonies were observed. These colonies were not identified by VITEK2 and Walkaway 96i without cysteine supplementation. The isolate was susceptible for cefotetan, ciprofloxacin and imipenem, and resistant for piperacillin/tazobactam, cephalothin, cefotaxime, ceftazidime, amikacin, gentamicin, and tobramycin.

본 연구에서는 식품에서의 L. monocytogenes에 대한 기초자료를 제공하고자 2010년부터 2011년까지 서울지역에서 수거된 식품 총 1042건에서 L. monocytogenes를 분리하여 항생제 감수성 검사를 하였다. 김밥 4건(0.8%), 육회 4건(2.6%), 연어제품 2건(11.1%), 돈육식품과 조리된 생선에서 각 1건씩(각5.9%, 6.3%) 총 12균주가 분리 동정되었다. 분리 균주를 20종의 항생제에 검사한 결과 대다수 항생제(16종)에 감수성을 나타내었지만 cefotetan (11균주), cefotaxime (7균주), cefepime (6균주)에서 내성을 나타냈으며 3균주에서 임상치료에 자주 사용되는 tetracycline에 대해서 내성을 나타내었다.

In this study, we isolated and characterized Escherichia coli from mussels and inland pollution sources in or in proximity to the Changseon area on the southern coast of Korea in 2014. A total of 147 strains of E. coli were isolated from 54 mussels and 32 pollution-source samples. The susceptibility of the isolates to 24 antimicrobial agents was analyzed. The resistance of E. coli isolates to rifampin was highest at 100%, followed by cephalothin (98.6%), tetracycline (91.8%), amikacin (81.0%), ampicillin (79.6%), cefazolin (79.6%), streptomycin (73.5%), piperacillin (70.7%), gentamicin (37.4%), cefoxitin (35.4%), cefamandole (34.7%), tobramycin (29.9%), amoxicillin/clavulanic acid (24.5%), nalidixic acid (21.8%), trimethoprim (19.0%), chloramphenicol (17.7%), cefotaxime (12.9%), trimethoprim (10.9%), ceftazidime (10.2%), aztreonam (7.5%), imipenem (2.7%), cefepime (2.0%), and cefotetan (0.0%). In addition, the antimicrobial resistance of E. coli isolates from inland pollution sources was slightly greater than or similar to that of isolates from mussels.
