A 4-year-old male Miniature Pinscher was referred because of head tilt, nystagmus, and ataxia. The hemogram revealed a moderate neutrophilic leukocytosis. On magnetic resonance imaging, cerebellar inflammation was detected. And cerebrospinal fluid analysis indicated marked neutrophilic pleocytosis. Based on these results, bacterial meningoencephalitis was suspected. The clinical signs were well controlled by a combination antibiotics therapy of the third generation cephalosporins (cefotaxime and cefixime) and metronidazole. We tentatively diagnosed this case as a bacterial meningoencephalitis because clinical signs were improved after only antibiotics therapy and relapsed when stopped antibiotics administrations, even though the result of bacterial culture on communication of cerebrospinal fluid (CSF) was negative.

Methylmalonic acidemia is an inborn error of branched chain amino acid metabolism, clinically characterized by lethargy, vomiting, and hypertonia with abnormal movements, and biochemically characterized by ketoacidosis, hyperammonemia, and sometimes hyperglycinemia. Conventional treatment of methylmalonic acidemia incluides dietary protein restriction, bicarbonate, carnitine, and metronidazole. However, most patient have recurrent episodes of acidosis, and a significant number have neurologic deficits and renal impairment. We report the successful treatment of a patient with methylmalonic acidemia by liver transplantation.

A two-year-old male Chinese Shar poi dog was admitted to the hospital because of chronic diarrhea. Abnormalities detected on physical examination were thickened intestinal loops and thin or cachexic body condition.4 complete blood count revealed a mild neutrophilia. The blood chemistry panel indicated no significant abnormalities. On proctoscopic examinations colonic mucosa was reddened and edematous. Numerous Iymphocytes, plasma cells and epithelial cells were observed in the cytologic examination of the rectal scraping.4 treatment was initiated with sulfasalazinei metronidazole and prednisolone and dietary management with rice and cottage cheese was performed simultaneously. Although antibiotic therapy and dietary management were donee the dog's condition deteriorated and died suddenly. Lymphocytic-plasmacytic enterocolitis was diagnosed by postmortem pathologic examination.

A 3-year-old intact female korean pungsan dog showing chronic intermittent vomiting and anorexia was admitted to The Veterinary Medical leaching Hospital of Seoul National University. The patient had been received antiemetics, antacids or proton pump inhibitor for these symptoms but had not been recovered yet. All results of physical examination, complete blood count, serum chemical analysis, fecal test and radiography were normal. Gastric endoscopic examination was also performed and gastritis with hemorrhage on near antrum region was detected. In PCR assay of bioptic gastric tissues for detecting Helicobacter species infection, Helicobacter heilmannii infection was confirmed. After receiving triple therapy with amoxicillin, metronidazole and omeprazole for 21 days, all symptoms were recovered and had not been occurred again. Helicobacter heilmannii also were not detected.

Regenerative endodontics has a potential to heal a partially necrotic pulp, which can be beneficial for the continued root development and strengthening of immature teeth. For this purpose, triple antibiotic mixture of ciprofloxacin, metronidazole, and minocycline was recommended as intracanal medicament in an attempt to disinfect the root canal system for revascularization of a tooth with a necrotic pulp. However, discoloration of the tooth was reported after applying this. This case shows the idea for preventing the tooth discoloration using a delivery syringe to avoid the contact between the clinical crown and the antibiotics.

A clinical suspicion of intestinal spirochetosis is required when patients have long lasting complaints of abdominal pain, diarrhea, rectal bleeding, weight loss, and nausea. An endoscopy with biopsies needs to be performed to confirm the diagnosis of intestinal spirochetosis. The diagnosis of intestinal spirochetosis is based on histological appearance. Intestinal spirochetosis can also be associated with other intestinal infections and juvenile polyps (JPs). JPs seem to be more frequent in patients with intestinal spirochetosis than in patients without intestinal spirochetosis. Intestinal spirochetosis in children should be treated with antibiotics. Metronidazole is the preferred option. In this article, we describe 4 cases of intestinal spirochetosis in a pediatric population and provide a review of the literature over the last 20 years. Intestinal spirochetosis is a rare infection that can cause a variety of severe symptom. It is diagnosed based on histological appearance.

An immature tooth with infected pulp has numerous potential complications. Conventional apexification with calcium hydroxide has several disadvantages, including susceptibility to tooth fracture. This method does not promote continual root development. Pulp revascularization of a necrotic, immature permanent tooth will allow further development of the root and dentinal structure. Disinfection of the root canal system is a prerequisite for pulp revascularization and tissue regeneration. A combination of antibiotic drugs (ciprofloxacin, metronidazole, and minocycline) is effective for disinfection of necrotic pulp, and has been used successfully in regenerative endodontic treatment. These case reports involve the treatment of 3 immature permanent teeth with necrotic pulp using a 3-Mix paste and mineral trioxide aggregate. All cases showed the notable apical maturation with closure of the apex and increased thickness of dentinal walls. This approach suggests a paradigm shift in treating endodontically involved immature permanent teeth from the traditional apexification with calcium hydroxide to the conservative approach by providing a favorable environment for tissue regeneration.

The purpose of this study was to evaluate the effect of the intracanal medicaments on the push-out bond strength of the calcium silicate-based materials. Forty extracted single-root human mandibular premolars were sectioned below cementoenamel junction. Standardized root canal dimension was obtained with a parallel post drill. The specimens were randomly divided into a control group (no medicament), and experimental groups received medicaments with either CH (calcium hydroxide), DAP (double antibiotic paste; a mixture of ciprofloxacin and metronidazole), or TAP (triple antibiotic paste; a mixture of minocycline, ciprofloxacin and metronidazole). Following removal of medicaments with irrigation, roots were cut into sections with 1-mm-thickness. Thereafter, calcium silicate-based materials are applied to the specimens : (i) ProRoot MTA$^{(R)}$ and (ii) Biodentine$^{(R)}$. A push-out bond strength was measured and each specimen was examined to evaluate failure mode. Intracanal medication using CH significantly increased the bond strength to the root dentin. But there are no significant differences on the bond strength of ProRoot MTA$^{(R)}$ or Biodentine$^{(R)}$ among TAP, DAP and control groups. The dislodgement resistance of Biodentine$^{(R)}$ from root dentin was significantly higher than that of ProRoot MTA$^{(R)}$ regardless of the type of intracanal medicaments.

Objectives: This study aimed to understand the nationwide patterns of antibiotic prescription after tooth extraction in adult patients. Materials and Methods: This study analyzed dental records from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) database on 503,725 tooth extractions performed in adults (≥19 years) during 2011-2015. Patient sex, age, household income, systemic disease (diabetes mellitus and hypertension), type of dental institution, region of dental institution, year of prescription, and type of tooth extraction procedure were considered. The antibiotic prescription rate and broad-spectrum antibiotic prescription frequency were analyzed using chi-squared tests. Factors affecting the prescription of broad-spectrum antibiotics were evaluated using multivariate logistic regression analysis. Results: The rate of antibiotic prescription after tooth extraction was 81.85%. Penicillin was most commonly prescribed (45.25%), followed by penicillin with beta-lactamase inhibitors (18.76%), metronidazole (12.29%), and second- to fourth-generation cephalosporins (11.52%). The proportion of broad-spectrum antibiotics used among all prescribed antibiotics was 45.88%. Conclusion: The findings of this study demonstrate that the rate of antibiotic prescription after tooth extraction is higher in Korea than in other countries. Furthermore, broad-spectrum antibiotics are used more frequently, which may indicate unnecessary drug prescription, an important contributor to antibiotic resistance.

Recurrent aphthous stomatitis (RAS) is a common oral mucosal disorder for which no curative treatment is available. We previously reported that decreased Streptococcus salivarius and increased Acinetobacter johnsonii on the oral mucosa are associated with RAS risk. The purpose of this study was to identify antibiotics that selectively inhibit A. johnsonii but minimally inhibit oral mucosal commensals. S. salivarius KCTC 5512, S. salivarius KCTC 3960, A. johnsonii KCTC 12405, Rothia mucilaginosa KCTC 19862, and Veillonella dispar KCOM 1864 were subjected to antibiotic susceptibility test using amoxicillin, cefotaxime, gentamicin, clindamycin, and metronidazole in liquid culture. The minimal inhibitory concentration (MIC) was defined as the concentration that inhibits 90% of growth. Only gentamicin presented a higher MIC for A. johnsonii than MICs for S. salivarius and several oral mucosal commensals. Interestingly, the growth of S. salivarius increased 10~200% in the presence of sub-MIC concentrations of gentamicin, which was independent of development of resistance to gentamicin. In conclusion, gentamicin may be useful to restore RAS-associated imbalance in oral microbiota by selectively inhibiting the growth of A. johnsonii but enhancing the growth of S. salivarius.
