A 50-year-old male underwent liver transplantation due to cryptogenic cirrhosis and was admitted with severe pain in the left leg as well as phlogosis. Amoxicillin/clavulanic acid was prescribed, assuming bullous erysipelas. Among the tests performed, the latex agglutination test for the Cryptococcus sp. antigen was positive, and in both the blood culture and blister culture Cryptococcus sp. was isolated. Daily fluconazole was started. Even though liposomal amphotericin B has been started on the fifth day of hospitalization, the patient progressed to death.

We present the case of a 58-year-old man who underwent urgent blowhole colostomy for toxic megacolon (TM) secondary to Clostridium difficile infection (CDI). This infection occurred under antibiotic coverage with amoxicillin-clavulanic acid, four days after laparoscopic sigmoidectomy in our hospital. Although prospective clinical research regarding the surgical management of TM is lacking, decompressive procedures like blowhole colostomy are reported to carry a high risk of postoperative morbidity and mortality and are widely regarded as obsolete. Subtotal or total colectomy with end ileostomy is currently considered the procedure of choice. After presenting our case, we discuss the literature available on the subject to argue that the scarce evidence on the optimal surgical treatment for TM is primarily based on TM associated with inflammatory bowel diseases (IBD) and that there might be a rationale for considering minimally invasive procedures like blowhole colostomy for CDI-associated TM.

Background. Elimination of bacteria from the root canal system is one of the aims of endodontic treatment; hence the incorporation of antibiotics into sealers can increase their antimicrobial efficacy. The aim of the present study was to determine the in vitro antimicrobial effects of AH26 and AH Plus sealers mixed with amoxicillin, triple antibiotic paste and nanosilver on Enterococcus faecalis. Methods. In this experiment, amoxicillin, triple antibiotic paste and nanosilver powder were added at 10% of the total sealer weight to AH26 and AH Plus sealers and then cultured freshly or after 1, 3, and 7 days with suspension of E. faecalis for 24 hours. The zones of growth inhibition for E. faecalis were evaluated in each group. Results. Incorporation of nanosilver did not increase antibacterial effects of the sealers. Sealers combined with amoxicillin exhibited the highest antibacterial efficacy in fresh condition. In the set specimens, the results demonstrated that the mixture of sealers and triple antibiotic pastes exhibited the greatest antibacterial efficacy. Conclusion. Amoxicillin and triple antibiotic paste significantly improved the antibacterial properties of AH Plus and AH26 sealers. Such properties decreased with time, but the use of sealer-amoxicillin/triple paste combination was still superior to using sealers alone or in combination with nanosilver.

A 69-year-old female with a history of bilateral total hip replacements presented with rigors, fever and sudden onset left groin pain. A pelvic X-ray showed well-fixed implants. Blood results revealed a leucocytosis (white cell count 22.3 × 10(9) l(-1)) and elevated C-reactive protein (211 mg/l). Ultrasound-guided aspiration of her left hip grew Streptococcus gordonii No source infection could be identified apart from a new chronic sinus infection in a left upper incisor. Following a discussion with the patient a 6-week course of intravenous ceftriaxone was started and was successful in normalizing her inflammatory markers. She was placed on long-term suppressive amoxicillin following this. Her suppressive antibiotic therapy was complicated by the development of a clostridium difficile infection and her antibiotics were changed to doxycycline. At 1-year follow-up, she was asymptomatic with no further episodes of groin pain or fever.
- MIC of amoxicillin/clavulanate according to CLSI and EUCAST: discrepancies and clinical impact in patients with bloodstream infections due to Enterobacteriaceae. [Journal Article]
- JAJ Antimicrob Chemother 2017 Jan 15
- CONCLUSIONS: CLSI and EUCAST methodologies showed low agreement for determining the MIC of amoxicillin/clavulanate. EUCAST-derived MICs seemed more predictive of failure than CLSI-derived ones. EUCAST-derived MICs >16/2 mg/L were independently associated with therapeutic failure.

Realistic implementation of ion selective electrodes (ISEs) into environmental monitoring programs has always been a challenging task. This could be largely attributed to difficulties in validation of ISE assay results. In this study, the electrochemical response of amoxicillin trihydrate (AMX), ciprofloxacin hydrochloride (CPLX), trimethoprim (TMP), and norfloxacin (NFLX) was studied by the fabrication of sensitive membrane electrodes belonging to two types of ISEs, which are polyvinyl chloride (PVC) membrane electrodes and glassy carbon (GC) electrodes. Linear response for the membrane electrodes was in the concentration range of 10(-5)-10(-2) mol/L. For the PVC membrane electrodes, Nernstian slopes of 55.1, 56.5, 56.5, and 54.0 mV/decade were achieved over a pH 4-8 for AMX, CPLX, and NFLX, respectively, and pH 3-6 for TMP. On the other hand, for GC electrodes, Nernstian slopes of 59.1, 58.2, 57.0, and 58.2 mV/decade were achieved over pH 4-8 for AMX, CPLX, and NFLX, respectively, and pH 3-6 for TMP. In addition to assay validation to international industry standards, the fabricated electrodes were also cross-validated relative to conventional separation techniques; high performance liquid chromatography (HPLC), and thin layer chromatography (TLC)-densitometry. The HPLC assay was applied in concentration range of 0.5-10.0 μg/mL, for all target analytes. The TLC-densitometry was adopted over a concentration range of 0.3-1.0 μg/band, for AMX, and 0.1-0.9 μg/band, for CPLX, NFLX, and TMP. The proposed techniques were successfully applied for quantification of the selected drugs either in pure form or waste water samples obtained from pharmaceutical plants. The actual waste water samples were subjected to solid phase extraction (SPE) for pretreatment prior to the application of chromatographic techniques (HPLC and TLC-densitometry). On the other hand, the fabricated electrodes were successfully applied for quantification of the antibiotic residues in actual waste water samples without any pretreatment. This finding assures the suitability of the fabricated ISEs for environmental analysis.
- An analysis of policies for cotrimoxazole, amoxicillin and azithromycin use in Namibia's public sector: Findings and therapeutic implications. [Journal Article]
- IJInt J Clin Pract 2017 Jan 16
- CONCLUSIONS: Policy and guidelines for antibiotic use in Namibia are not comprehensive and are skewed towards PHCs. Existing policies promote the wide use of CAA antibiotics, which may inadvertently result in their inappropriate use enhancing resistance rates. This calls for the development of more comprehensive antibiotic guidelines and essential medicine lists in tandem with local antimicrobial resistance patterns. In addition, educational initiatives among all key stakeholder groups.

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv.
