For examination of antibiotic therapeutic efficacy in canine brucellosis, this examination was carried out two female bitches infected with Brucella canis in Gyeongbuk province, and used combicillin, baytril and doxycycline in susceptible antibiotics at B canis. During 18 month after the termination of antibiotic therapy, blood sample of the two bitches were examined for B canis antibody and antigen. The antibody of one bitch was disappeared at 5 month after antibiotic therapy and the other was continued at 18 month, but two bitches were not detected antigen by blood culture and PCR. Examination of blood chemical value (AST, ALT, urea, creatinine) of two bitches was increased in AST value during antibiotic therapy.

Ventilator-associated pneumonia (VAP) is the most frequent nosocomial infection in the intensive care unit (ICU), with an incidence ranging from 8% to 38%. Patients who acquire VAP have higher mortality rates and longer ICU and hospital stays. Because there are other potential causes of fever, leukocytosis, and pulmonary infiltrates, clinical diagnosis of VAP is overly sensitive. The only alternative approach to the clinical diagnosis of VAP is the Clinical Pulmonary Infection Score (CPIS). Employing quantitative cultures of respiratory secretions in the diagnosis of VAP leads to less antibiotic use and probably to lower mortality. With respect to microbiologic diagnosis, however, it is not clear that the use of invasive sampling using bronchoscopy is associated with better outcomes. Delayed administration of antibiotic therapy is associated with an increased mortality, and inadequate antibiotic therapy is also associated with higher mortality. Therefore, prompt initiation of adequate antibiotic therapy is a cornerstone of the treatment of VAP. The initial antibiotic therapy should be based on the most common organisms in each hospital and the most likely pathogens for that specific patient. When final cultures and susceptibilities are available, de-escalation to less broad spectrum antibiotics should be done. Since clinical improvement usually takes 2 to 3 days, clinical responses to the initial empirical therapy should be evaluated by day 3. A short course of antibiotic therapy appears to be equivalent to a traditional course of more than 14 days, except when treating non-fermenting gram-negative organisms. If patients receive initially adequate antibiotic therapy, efforts should be made to shorten the duration of therapy to as short as 7 days, provided that the etiologic pathogen is not a non-fermenting gram-negative organism.

Purpose: The study was done to explore whether the duration of perioperative prophylactic antibiotics therapy influenced uncertainty of recovery in patients with elective laparoscopic uterine myomectomy. Methods: A prospective study was conducted using self-report questionnaires and electrical medical records for patients with uterine myomectomy. According to the length of the perioperative prophylactic antibiotics therapy, the patients were divided into three groups: single-dose antibiotic treatment group, short-term antibiotic treatment group, and long-term antibiotic treatment group. Data were collected from December 20, 2016 to July 31, 2017 from 161 patients who underwent laparoscopic myomectomy at a metropolitan city general hospital. Results: Level of uncertainty of recovery was $2.98{\pm}0.22$. The uncertainty was highest in the long-term antibiotic treatment group, followed by the short-term antibiotic treatment group and the single-dose antibiotic treatment group (F=89.40, p<.001). In the regression analysis, factors influencing uncertainty of recovery among uterine myomectomy patients were duration of perioperative prophylactic antibiotic therapy (${\beta}=.70$, p<.001) and duration of NPO (${\beta}=-.11$, p=.047) which explained 51.5% of the variance (F=83.75, p<.001). Conclusion: Based on these results, information including the administration of antibiotics before surgery should be provided to the patients to help reduce the uncertainty of postoperative recovery.

Pyogenic liver abscesses are rare in children. In pediatric patients, altered host defences seem to play an important role. However, pyogenic liver abscess also occurs in healthy children. We experienced a case of pyogenic liver abscess in a healthy immunocompetent 10-year-old-girl. The patient presented two distinct abscesses: one subphrenic and the other intrahepatic. The intrahepatic abscess resolved with percutaneous drainage and 3 weeks of parenteral antibiotic therapy but the subphrenic abscess which could not be drained needed prolonged parenteral antibiotic therapy in addition to oral antibiotic therapy. We performed follow-up serial CT scan of the abscess cavity to decide on the duration of antibiotic therapy. Here we present this case with a brief review of the literature.

Conservative therapy with appropriate antibiotics is essential for most patients with infectious spondylitis. Although most antibiotics do not cause problems if it used properly and serious side effects are rare, side effects can occur with any class of drugs and adverse reactions of antibiotics can range from mild allergic reactions to serious and fulminant adverse events. These side effects are also extremely variable from patient to patient and from antibiotic to antibiotic. A side effect of antibiotics may paradoxically increase inflammatory marker levels. Here, the author presents two cases of antibiotic-induced increase in inflammatory markers in cured infectious spondylitis. The patients were successfully treated after stopping the antibiotic therapy. The differential diagnosis between antibiotic side effects and infection should be considered very carefully because the treatment is completely different. Although the exact mechanisms underlying successful treatment without antibiotics are unclear, we should consider the side effects of antibiotics when following inflammatory markers during treatment of infectious spondylitis.

Mycobacterium fortuitum usually causes colonization or transient infection in patients with underlying lung disease, such as prior tuberculosis or bronchiectasis. The majority of these patients may not need to receive antibiotic therapy for M. fortuitum isolates. We report here on a patient with M. fortuitum lung disease and who was successfully treated with combination oral antibiotic therapy. A 53-year-old woman was referred to our institution because of purulent sputum and dyspnea. A chest radiograph and computed tomography scan revealed cavitary consolidation in the left upper lobe and multiple small cavities in the left lower lobe. Numerous acid-fast bacilli (AFB) were seen in multiple sputum specimens and M. fortuitum was identified by culture from the sputum specimens. The patient received antibiotic treatment including clarithromycin, ciprofloxacin and sulfamethoxazole, because her symptoms were worsening despite conservative treatment. Sputum conversion was achieved after one month of antibiotic therapy. Both the patient's symptoms and radiographic findings improved after 10 months of antibiotic therapy.

Objectives The purpose of this study is to examine the correlation of antibiotics administration duration and antimicrobial resistance by reviewing domestic and foreign literatures. Methods We searched literatures dated up to 23 February, 2018 in PubMed and Cochrane Library using terms of "Anti-Bacterial Agents", "Carrier State", "Nasopharynx", "Drug Administration Schedule", and also searched via RISS (Research Information Service System), KISS (Koreanstudies Information Service System), DBpia (DataBase Periodical Information Academic) using terms of antibiotics, resistance, and dose. Results In comparison with shortened and standard antibiotic course, longer treatment duration is associated with greater antimicrobial resistance or non-significant difference, but we cannot find literature that shortened antibiotic course increases antimicrobial resistance on human nasopharyngeal flora. Conclusions Currently, there is no evidence that completing the standard antibiotic course reduces antimicrobial resistance. It can be a strategy for reducing antibiotic use to apply Korean medicine treatment, as well as short-course antibiotic therapy or delayed antibiotic prescription. Additional well-designed trials should be conducted in domestic and foreign settings about the appropriate duration of antibiotic therapy.

Antibiotic is one of the mainly prescribed drugs in dental office. The substantial part of all antibiotics used in dental office is given to patients without signs or symptoms of infection to prevent infections, and antibiotics became the most widely abused prescribed drugs on the basis of inappropriate indications, dosages and durations. Considering that antibiotics are one of the drugs that affect not only a single patient but also entire populations of individuals through their collective effects on microbial ecology, the importance of proper use of antimicrobial therapy can hardly be overemphasized. Therefore, the main considerations for antibiotic therapy in denial office were summarized here.

As the field of interventional pain management (IPM) grows, the risk of surgical site infections (SSIs) is increasing. SSI is defined as an infection of the incision or organ/space that occurs within one month after operation or three months after implantation. It is also common to find patients with suspected infection in an outpatient clinic. The most frequent IPM procedures are performed in the spine. Even though primary pyogenic spondylodiscitis via hematogenous spread is the most common type among spinal infections, secondary spinal infections from direct inoculation should be monitored after IPM procedures. Various preventive guidelines for SSI have been published. Cefazolin, followed by vancomycin, is the most commonly used surgical antibiotic prophylaxis in IPM. Diagnosis of SSI is confirmed by purulent discharge, isolation of causative organisms, pain/tenderness, swelling, redness, or heat, or diagnosis by a surgeon or attending physician. Inflammatory markers include traditional (C-reactive protein, erythrocyte sedimentation rate, and white blood cell count) and novel (procalcitonin, serum amyloid A, and presepsin) markers. Empirical antibiotic therapy is defined as the initial administration of antibiotics within at least 24 hours prior to the results of blood culture and antibiotic susceptibility testing. Definitive antibiotic therapy is initiated based on the above culture and testing. Combination antibiotic therapy for multidrug-resistant Gram-negative bacteria infections appears to be superior to monotherapy in mortality with the risk of increasing antibiotic resistance rates. The never-ending war between bacterial resistance and new antibiotics is continuing. This article reviews prevention, diagnosis, and treatment of infection in pain medicine.

Syphilis, one of the most common sexually transmitted diseases, is caused by the microorganism Treponema pallidum. Syphilis consists of several clinical stages that may include signs in the oral and perioral regions. Syphilis is treated effectively with systemic antimicrobial therapy using antibiotics such as penicillin. This article describes a case where topical antibacterial therapy with doxycycline was effective in treating oral papular lesions associated with primary syphilis in a 24-year-old male. He was immediately referred to a dermatologist, and antibiotic therapy was administered in response to positive diagnostic test results for syphilis. Although oral syphilitic lesions may be resolved by dental professionals using topical treatments, syphilitic infections should be managed in consultation with medical specialists using systemic antibiotic therapy.
