RESUMEN
Amoxicillin/clavulanate (co-amoxiclav) is a widely used antibiotic in community healthcare settings, combining amoxicillin and clavulanate potassium to combat ß-lactamase-producing bacteria. Despite its extensive use, limited pharmacokinetic/pharmacodynamic data support current dosing guidelines. This review explores the significance of high-dose co-amoxiclav (875 mg/125 mg) in treating various infections amidst rising antibiotic resistance. A comprehensive narrative literature review was conducted using MEDLINE, PubMed, and Google Scholar, focusing on co-amoxiclav 875 mg/125 mg from 1992 to 2024. Keywords included "Co-amoxiclav 875mg/125mg," "amoxicillin 875mg," "Co-amoxiclav dosing," "pharmacology," "PK," and "safety." Studies on non-safety aspects, those on cost-effectiveness, non-English articles, and those without full-text access were excluded. Clinical efficacy studies demonstrate the effectiveness of co-amoxiclav (875 mg/125 mg) in treating conditions such as cutaneous actinomycosis, actinomycetoma, lower respiratory tract infections, acute bacterial maxillary sinusitis, and community-acquired pneumonia. Comparative studies reveal similar or superior efficacy of co-amoxiclav (875 mg/125 mg) compared to other dosing regimens and antibiotics such as clindamycin, cefaclor, cefuroxime, and ciprofloxacin. Safety and tolerability assessments indicate that co-amoxiclav is generally well-tolerated, with common mild-to-moderate gastrointestinal side effects. In summary, co-amoxiclav 1 gm remains a crucial antibiotic with optimized dosing regimens enhancing clinical outcomes while addressing resistance challenges.
RESUMEN
A black hairy tongue is a benign, self-limiting condition characterized by the discolouration of the tongue due to defective desquamation. Clinical presentation varies, with most cases being asymptomatic although aesthetically unpleasant to the patient. Prevalence varies geographically, ranging from 0.6% to 11.3%. It can be triggered by various factors such as medications, smoking, alcohol, poor oral hygiene, or even underlying systemic conditions such as malignancy. Several antibiotics such as doxycycline, erythromycin, amoxicillin-clavulanate, metronidazole, and piperacillin-tazobactam, have been reported to cause black hairy tongues. Onset can range from a few weeks to as long as five weeks. Diagnosis relies on clinical assessment with a good history and visual examination. Definitive treatment remains unclear, but the condition typically improves by identifying and discontinuing the causative agent and maintaining adequate oral hygiene. Complications are rare, and the prognosis is excellent. This case report aims to raise awareness of the association between the black hairy tongue and co-amoxiclav, which may impose additional burdens on patients, healthcare providers, and the health system if failed to be recognized and treated appropriately.
RESUMEN
OBJECTIVES: Current guidelines recommend broad-spectrum antibiotics for high-severity community-acquired pneumonia (CAP), potentially contributing to antimicrobial resistance (AMR). We aim to compare outcomes in CAP patients treated with amoxicillin (narrow-spectrum) versus co-amoxiclav (broad-spectrum), to understand if narrow-spectrum antibiotics could be used more widely. METHODS: We analysed electronic health records from adults (≥16 y) admitted to hospital with a primary diagnosis of pneumonia between 01-January-2016 and 30-September-2023 in Oxfordshire, United Kingdom. Patients receiving baseline ([-12 h,+24 h] from admission) amoxicillin or co-amoxiclav were included. The association between 30-day all-cause mortality and baseline antibiotic was examined using propensity score (PS) matching and inverse probability treatment weighting (IPTW) to address confounding by baseline characteristics and disease severity. Subgroup analyses by disease severity and sensitivity analyses with missing covariates imputed were also conducted. RESULTS: Among 16,072 admissions with a primary diagnosis of pneumonia, 9685 received either baseline amoxicillin or co-amoxiclav. There was no evidence of a difference in 30-day mortality between patients receiving initial co-amoxiclav vs. amoxicillin (PS matching: marginal odds ratio 0.97 [0.76-1.27], p = 0.61; IPTW: 1.02 [0.78-1.33], p = 0.87). Results remained similar across stratified analyses of mild, moderate, and severe pneumonia. Results were also similar with missing data imputed. There was also no evidence of an association between 30-day mortality and use of additional macrolides or additional doxycycline. CONCLUSIONS: There was no evidence of co-amoxiclav being advantageous over amoxicillin for treatment of CAP in 30-day mortality at a population-level, regardless of disease severity. Wider use of narrow-spectrum empirical treatment of moderate/severe CAP should be considered to curb potential for AMR.

BACKGROUND: The prescription of antibiotics in dental practice contributes significantly to the total use of antibiotics in primary healthcare. This study aimed to evaluate antibiotic prescription in dental practice during the years 2016-2021 in Norway and their relative contribution to national outpatient consumption and to investigate the influence of age, gender, geographic region, and COVID-19. A further aim was to review differences in prescribing patterns to verify effect of governmental strategies to reduce over-prescribing of antibiotics. METHODS: This register study investigated the national antibiotic prescription between 2016 and 2021. Data was obtained from the Norwegian prescription register, the Norwegian Institute of Public Health and Statistics Norway. The consumption of 12 common antibiotics was measured using WHO defined daily doses (DDDs), DDD per 1000 inhabitants per day (DIDs 1000). RESULTS: A total of 6,049,445 antibiotic prescriptions of the 12 investigated compounds were issued in primary care during the study period. Dentists accounted for 942,350 prescriptions corresponding to 15.6% of the total. An overall decrease in the number of prescriptions by health professions other than dentists during the 5 years (IRR = 0.92, 95% CI:0.92-0.93, p < 0.001) was observed. For dentists a slight increase in the number of prescriptions (IRR = 1.01, 95% CI: 1.01-1.01, p < 0.001) was seen over the study period. The increase of antibiotic prescriptions in dentistry was more pronounced during the COVID-19 pandemic. The 4 most prescribed type of antibiotics based on average number of DDDs of the total period 2016-2021 were in descending order; phenoxymethylpenicillin (1,109,150) followed by amoxicillin (126,244), clindamycin (72,565), and metronidazole (64,599). An unexpected finding was that the prescription of the combination compound amoxicillin/clavulanic acid had significantly increased in dentistry during the last 5 years. Geographic, gender, and age differences in the rates of prescriptions were also seen. The data revealed that there are seasonal variations in dental prescriptions. CONCLUSIONS: Noticeable differences exist in prescribing patterns of antibiotics in the last 5 years. Restricted access to dental care due to COVID-19 may have resulted in increased antibiotic prescribing in dentistry as opposed to an otherwise downward trend. Despite national guidelines there is still a need for improvement of antibiotic stewardship in dentistry and to define effective methods to disseminate information.

BACKGROUND: Probiotics are co-prescribed with co-amoxiclav to prevent antibiotic-associated diarrhea (AAD). The study assesses the co-prescription pattern of probiotics with co-amoxiclav in pediatric patients with respiratory tract infections (RTIs). METHODS: This was a mixed methods research study with a retrospective study and a prospective survey. The retrospective part included a multicenter, observational, real-world study utilizing patients' electronic medical records for three years (2018-2020) from seven outpatient pediatric clinics and hospitals. The qualitative evaluation was performed with a predefined questionnaire. RESULTS: The patients having RTIs (N=984) were prescribed Clamp® (46.7%), CAA (23.8%), and CAM (29.5%). The mean age of the patients was 4.05 years, with 59.25% males and most patients having upper RTIs. Co-amoxiclav was prescribed twice daily for one to 15 days. A significantly lesser number of probiotic co-prescriptions were observed with Clamp® (19.57%) than with CAA (38.46%) and CAM (29.31%) at baseline (p<0.001). Similar findings were observed for follow-up visits one and two. Saccharomyces boulardii, Bacillus clausii,and lactic acid bacillus were the most commonly co-prescribed probiotics. The qualitative evaluation indicated that most clinicians were aware of the co-amoxiclav-related gastrointestinal side effects and the benefits of probiotics in preventing them. CONCLUSION: The frequency of co-prescriptions of probiotics with Clamp® among pediatric patients with RTIs was significantly less, potentially indicating better gastrointestinal tolerability.
RESUMEN
BACKGROUND: Antibiotic prescribing is more prevalent in children. Many factors influence this practice, including the burden of outpatient visits. We aimed to compare antibiotic prescribing for children by low prescribers (LP) and high prescribers (HP) in primary care. METHODS: We analyzed pediatric prescriptions in primary care in Istanbul. Among the physicians randomly selected by systematic sampling, those generating ≥1 pediatric prescription/day (n=1218) were defined as LP or HP when they belonged to the lowest (n=305) or highest (n=304) quartile of prescribing, respectively. The antibiotic prescribing characteristics of these groups were compared. RESULTS: We identified that 38.5% of the prescriptions written by physicians included antibiotics, significantly higher in HPs (38.8%) than in LPs (37.2%), (p=0.04). Among antibiotic-containing prescriptions, the mean number of drugs and boxes and the percentage of prescriptions containing injectable drugs/antibiotics were significantly higher in HPs compared to that in LPs. We detected that co-amoxiclav was the most frequently prescribed antibiotic in the LP and HP groups (61.1% and 48.3%, respectively). Stratification of antibiotics by their spectra showed that 11.2% were narrow, 79.8% were broad and 0.5% were ultra-broad-spectrum drugs. LPs were significantly more likely to prescribe broad-spectrum antibiotics (82.5%) than do HPs (78.9%,p < 0.001). CONCLUSIONS: Antibiotic prescribing remains excessive in pediatric primary care, slightly more marked in HPs. While HPs also tend to prescribe a higher number of overall and injectable drugs/antibiotics, broad-spectrum anti-biotherapy seems to be more practiced by LPs surprisingly. Both physician groups appeared to prefer either narrow- or broad-spectrum drugs without paying enough attention to their pharmacodynamic properties.

Background: Idiosyncratic drug-induced liver injury (DILI) is a serious uncommon disease that may develop as a result of the intake of certain drugs such as the antimicrobials flucloxacillin and co-amoxiclav. The reported cases showed significant associations between DILI and various human leukocyte (HLA) markers. The solute carrier organic anion transporter 1B1 (SLCO1B1), a non-HLA candidate gene, was previously reported as a risk factor for liver injury induced by rifampin and methimazole. This study presumed that SLCO1B1 may play a general role in the DILI susceptibility and therefore investigated the association of rs4149056 (SLCO1B1*5, T521C) polymorphism with flucloxacillin- and co-amoxiclav-induced liver injury. Methodology: We recruited 155 and 165 DILI cases of white ancestral origin from various European countries but mainly from the United Kingdom owing to flucloxacillin and co-amoxiclav, respectively. Only adult patients (≥18 years) who were diagnosed with liver injury and who showed i) clinical jaundice or bilirubin >2x the upper limit of normal (ULN), ii) alanine aminotransferase (ALT) >5x ULN or iii) alkaline phosphatase (ALP) >2x ULN and bilirubin > ULN were selected. The population reference sample (POPRES), a European control group (n = 282), was used in comparison with the investigated cases. TaqMan SNP genotyping custom assay designed by Applied Biosystems was used to genotype both DILI cohorts for SLCO1B1 polymorphism (rs4149056). Allelic discrimination analysis was performed using a step one real-time PCR machine. Genotype differences between cases and controls were examined using Fisher's exact test. GraphPad Prism version 5.0 was used to determine the p-value, odds ratio, and 95% confidence interval. Compliance of the control group with Hardy-Weinberg equilibrium was proven using a web-based calculator available at https://wpcalc.com/en/equilibrium-hardy-weinberg/. Results: A small number of cases failed genotyping in each cohort. Thus, only 149 flucloxacillin and 162 co-amoxiclav DILI cases were analyzed. Genotyping of both DILI cohorts did not show evidence of association with the variant rs4149056 (T521C) (OR = 0.71, 95% CI = 0.46-1.12; p = 0.17 for flucloxacillin cases and OR = 0.87, 95% CI = 0.56-1.33; p = 0.58 for co-amoxiclav), although slightly lower frequency (22.8%) of positive flucloxacillin cases was noticed than that of POPRES controls (29.4%). Conclusion: Carriage of the examined allele SLCO1B1*5 is not considered a risk factor for flucloxacillin DILI or co-amoxiclav DILI as presumed. Testing a different allele (SLCO1B1*1B) and another family member gene (SLCO1B3) may still be needed to provide a clearer role of SLCO1B drug transporters in DILI development-related to the chosen antimicrobials.
RESUMEN
BACKGROUND: Antibiotic choice for complicated appendicitis should be based on both microbiological effectiveness as well as ease of administration and cost especially in lower resourced settings. Data is limited on comparative morbidity outcomes for antibiotics with similar microbiological spectrum of activity. Incidence and morbidity of surgical site infection after appendectomy for complicated appendicitis was assessed after protocol change from triple antibiotic (ampicillin, gentamycin, and metronidazole) regimen to single agent (amoxycillin/clavulanic acid). METHODS: Surgical site infection (SSI) rate, relook surgery rate and length of hospital stay were retrospectively compared in patients treated for acute appendicitis preceding (2014, 2015; "triple-therapy, TT") and following (2017, 2018; "single agent, SA") antibiotic protocol change. RESULTS: The rate of complicated appendicitis was similar between groups; 72.6% in TT and 66% in SA (p = 0.239). Significantly, SSI occurred in 22.7% of the SA group compared to 13.3% in TT group (OR 1.920, 95% CI 1.000-3.689, p = 0.048). Use of laparoscopy increased from 31% in TT to 89% in SA, but with subgroup analysis this was not associated with increased SSI (17.3% in open and 20.6% in laparoscopic; OR 0.841, 95% CI 0.409-1.728, p = 0.637). Relook rate (OR 1.444, 95% CI 0.595-3.507, p = 0.093) length of hospital stay (U = 6859, z = -1.163, p = 0.245), and ICU admission (U = 7683, z = 0.634 p = 0.522) were equivocal. Neither group had mortalities. CONCLUSIONS: Despite increased SSI with SA, overall morbidity relating to ICU admission, relook rate and length of hospital stay was similar in both groups. More prospective research is required to confirm equivalent overall morbidity and that single agent therapy is more cost-effective with acceptable clinical outcomes.

Lawsonella clevelandensis is an anaerobic, partially acid-fast, Gram-positive bacillus associated with abscess formation. We present the case of a 70-year-old male with chronic contained rupture of abdominal aortic aneurysm (CCR-AAA) complicated by intra-abdominal abscess formation. An abdominal computed tomography scan revealed a rim-enhancing retroperitoneal collection tracking into the subcutaneous layer of the left flank and buttock, suggestive of CCR-AAA with infected haematoma. He underwent ultrasound-guided needle aspiration of the intra-abdominal collection. Conventional culture techniques failed to isolate L. clevelandensis , and the diagnosis was only confirmed by means of 16S rRNA PCR. The patient underwent branched endovascular repair of his aneurysm, and was commenced on treatment with co-amoxiclav, resulting in significant reduction in the size of the infected collection. This is only the second reported case of infection with L. clevelandensis in the UK, and the first reported case of this organism causing infected CCR-AAA.
RESUMEN
OBJECTIVES: This study aimed to describe patterns of prescribing co-amoxiclav to children aged ≤5 years at a polyclinic in Oman and to assess level of adherence to the antibiotic prescription guidelines outlined by the Omani Ministry of Health (MOH). METHODS: This cross-sectional retrospective study was conducted between June and December 2017 at Ibri Polyclinic (IPC) in Ibri, Oman. A random sample of 399 children aged ≤5 years who were prescribed a suspension of co-amoxiclav over the four winter months of 2016 were included in the study. The children's electronic medical records were reviewed to determine whether the prescription complied with MOH guidelines. RESULTS: The majority of the children were 2-3 years old (52.4%). Overall, 73.9% of prescriptions were written by general practitioners, while 26.1% were written by specialists. Co-amoxiclav therapy was the first line of management in 90.5% of cases, regardless of category of prescriber. Culture tests were ordered in only 43 cases (10.8%), of which five (11.6%) were found to be sensitive to the prescribed co-amoxiclav. CONCLUSION: Unnecessary antibiotics were prescribed to many paediatric patients attending IPC. Strict enforcement of the MOH antibiotic guidelines is needed to reduce irrational or discretionary prescription of this type of antibiotic. Healthcare providers should receive additional training in evidence-based methods of prescribing antibiotics.

RATIONALE: Previously, we have been able to outpace bacterial mutation by replacing increasingly ineffective antibiotics with new agents. However, with the discovery of new antibiotics diminishing, optimising the administration of existing broad-spectrum antibiotics such as co-amoxiclav has become a necessity. METHODS: A stability indicating HPLC method was developed and validated in compliance with International Council for Harmonisation (ICH) guidelines. Stability of co-amoxiclav at clinical concentration was evaluated at three temperatures (4°C, ambient (23-25°C) and 37°C) in three diluents (water for injection (WFI), 0.9% w/v NaCl and Ringer's solution). To establish whether there were significant differences at the level of both diluent and temperature, results were analysed using analysis of covariance (ANCOVA) to assess differences between the attained slopes of regression. RESULTS: Data obtained indicated co-amoxiclav stability superior to that previously proposed making it suitable for extended infusion therapy. The degradation of amoxicillin appeared to follow a linear trend, with the rate of degradation elevated at higher temperatures, demonstrated by the magnitude of the regression slopes in these conditions. Analysis of regression slopes via ANCOVA demonstrated that diluent and temperature both significantly affected co-amoxiclav stability. Amoxicillin retained 90% of its initial concentration for 7.8 to 10 hrs when stored at 4°C, 5.9 to 8.8 hrs at ambient and 3.5 to 4.5 hrs when incubated at 37°C. CONCLUSION: Co-amoxiclav is suitable for administration via prolonged infusion. Findings from this study aid in ameliorating current dosing regimens to optimise antibiotic efficacy. Other valuable applications conferred from these findings include the ability to pre-prepare solutions for use in bolus administration, minimising preparation time and workload.

The liver is susceptible to drug toxicity due to its vital role in xenobiotic metabolism and elimination. In addition to human leukocyte antigen (HLA) variants, which were previously determined as risk factors for drug-induced liver injury (DILI) due to co-amoxiclav, other non-HLA genes may contribute to hepatotoxicity risk. In this study, the association between DILI due to co-amoxiclav and several non-HLA genes was investigated. Association of variants in candidate genes (SOD2, GPX1, GSTM1, and GSTT1) with DILI due to various drugs was reported previously in other DILI cohorts. This study examined relevance in a co-amoxiclav-DILI cohort. One hundred sixty-five co-amoxiclav DILI cases were recruited from several European countries by two different studies (DILIGEN and iDILIC). A North-East England population group (n = 334) was used as the control group. PCR assays were used to genotype for the GSTM1 and GSTT1 null alleles with TaqMan SNP genotyping assays used for SOD2 (rs4880) and GPX1 (rs1050450). Fisher's exact test was used to assess differences in significance between cases and controls. None of the studied variants (SOD2 rs4880, GPX1 rs1050450, GSTM1 null allele, and GSTT1 null allele) was significantly associated with co-amoxiclav DILI compared with the control group. No significant differences between cases and controls were seen when combined SOD2/GPX1 genotypes and GST genotypes were considered. Despite the possible functional relevance and the previously reported contribution of the selected genes to DILI, our study failed to confirm associations between the selected genes and liver injury induced by co-amoxiclav.

OBJECTIVES: To compare postoperative infection and graft uptake rate using single dose of intravenous co-amoxiclav versus no antibiotic in children undergoing myringoplasty. METHODS: This is a prospective, randomized controlled study conducted in children of age 6-15 years with chronic otitis media (COM) mucosal, inactive type undergoing myringoplasty. Postoperative infection over a period of 4 weeks and status of graft at or around 3 months after surgery was studied as outcome measure. RESULTS: Fifty five out of sixty children completed follow-up. The overall postoperative infection rate was 5.4%. Postoperative infection rate was 3.5% in children receiving prophylactic antibiotic and 7.4% in children receiving no antibiotic. There was no statistically significant difference in postoperative infection between two groups (P > 0.05). The overall graft uptake rate was 87.27%. It was 85.7% in antibiotic used group and 88.8% in non-antibiotic group with no statistically significant difference (P > 0.05). CONCLUSIONS: Postoperative infection following myringoplasty in children is uncommon as it is a clean type of surgery. There was no statistically significant difference in postoperative infection and graft uptake rate by the use of prophylactic antibiotic in the intraoperative period. This study shows no benefit of a prophylactic antibiotic on postoperative infection or graft success in myringoplasty in children. TRIAL REGISTRATION NUMBER: NCT03700814.

Co-amoxiclav is used as a routine prophylactic antibiotic in surgical procedures. We present a case of 61 years old lady came to outpatient clinic with a diagnosis of right sided lower alveolar tumour. A plan was made to proceed with a Right Marginal Mandibulectomy. She received Co amoxiclav as prophylactic antibiotic and was clinically uneventful. On further questioning there were many different occasions on which the patient had oral co amoxiclav with no complications or side effects. No known drug allergies or otherwise were documented. As a part of surgical antibiotic prophylaxis, Co amoxiclav 1.2 gm was given to patient at the time of induction. After the antibiotic administration patient started having bronchospasm with increased airway pressures and severe hypotension indicating anaphylactic reaction. The patient was resuscitated, recovered from the anaphylactic shock successfully and provided extended recovery in post anaesthesia care unit followed by High Dependency Unit for overnight monitoring. Every centre or ward that administers injectable antibiotics have to have a standard protocol for the management of allergy reactions. A timely fashion is mandatory to make the best use of the drugs available and emergency gadget ought to be in vicinity in case this type of state of affairs rise up.

This article presents the efficacy of co-amoxiclav in two patients with ankylosing spondylitis. Both patients were administered oral co-amoxiclav for 7 days. The primary efficacy variable was the ankylosing spondylitis activity index. Secondary outcome measures were the ankylosing spondylitis functional index and spinal mobility. We detected a marked improvement in all symptoms and physical examination parameters. Co-amoxiclav has been shown to be effective against ankylosing spondylitis.

Clinical studies have shown that several classes of antibiotics are evidenced in drug induced liver injury. The combination of amoxicillin with clavulanic acid is commonly cited in such cases. Accordingly, the present study investigated the potential hepatoprotective and in vivo antioxidant efficacy of sage essential oil in Co-amoxiclav induced hepatotoxicity in rats. Sage essential oil was hydrodistilled from the aerial parts of Salvia officinalis L. and its compositional analysis was characterized by Gas chromatography-Mass spectroscopy. Rats were treated singly or concomitantly with Co-amoxiclav and sage essential oil for a period of seven days. The major components of sage oil as identified by GC-MS were 1,8-cineole, ß-pinene, camphor, ß-caryophyllene, α-pinene and α-caryophyllene comprising 26.3%, 14.4%, 10.9%, 7.8%, 6% and 2.5% respectively. The in vivo exposure of rats to Co-amoxiclav resulted in hepatotoxicity biochemically evidenced by the significant elevation of serum AST, ALT, ALP, γ-GT, total bilirubin and histologically conveyed by hydropic, inflammatory and cholestatic changes in rats' liver. Oxidative stress mediated the hepatic injury as indicated by the significant escalation in lipid peroxidation, as well as, the significant depletion of both glutathione level and glutathione dependent enzymes' activities. The concomitant administration of sage essential oil with Co-amoxiclav exerted a hepatoprotective effect via inducing an in vivo antioxidant defense response eventually regressing, to some extent, the hepatoarchitectural changes induced by Co-amoxiclav. Results suggest that sage essential oil is a potential candidate for counteracting hepatic injury associating Co-amoxiclav and this effect is in part related to the complexity of its chemical composition.
RESUMEN
BACKGROUND: We have conducted this study to evaluate the effect of antibiotics, whether oral or intravenous, compared to no antibiotic protocol on post-tonsillectomy morbidity. METHODS: A total of 270 patients aged 3 - 12 years were included in the study. Patients were assigned into three groups randomly; each group consisted of 90 patients. In the first group (group A), patients were given intravenous injections of ceftriaxone 50 mg/kg/24 hours in divided doses, the second group (group B) received oral co-amoxiclav (dose according to weight) for 5 days post-operatively, and in the third group, patients were not given antibiotics. Patients were evaluated for the incidence of any bleeding, number of days before resuming normal diet, incidence of nausea and vomiting, incidence of abdominal pain, frequency of analgesic use in the first week, and pain. RESULTS: Our study groups were comparable in age, gender, and weight. There were no statistically significant differences between our study groups with regard to the incidence of post-tonsillectomy bleeding, time relapsed to resume normal diet, and pain score scale. Incidence of nausea, vomiting, and abdominal pain was more in the oral antibiotic group, and it was statistically significant. CONCLUSION: We do not recommend the routine use of antibiotics in post-tonsillectomy period in pediatric age group and oral antibiotics prove to have worse outcome with regard to the incidence of nausea, vomiting, and abdominal pain, and these recommendations need to be evaluated by multicenter evaluation.
RESUMEN
A retrospective case note review of postoperative infections within 30 days of colorectal surgery was completed. Surgical site infections (SSIs) were identified in 22% of patients (84/378), with other infections, e.g. urinary tract infections, identified in 18.3% of patients. SSIs, urinary and respiratory tract infections were all associated with increased durations of hospital admission compared with non-infected patients. Consideration should be given to postoperative surveillance for all infections, using antibiotic consumption as an objective outcome measure. Nine percent of patients developed an organ space SSI. Organ space SSIs were associated with the longest additional duration of hospital admission (15.5 days) and were the only infection associated with an increase in mortality at 1 year; 37% (13/35) mortality with an organ space SSI vs 4% (8/225) without an infection (odds ratio = 16, 95% confidence interval = 6, 43). Further research to prevent and treat organ space SSIs should be prioritized.

Stevens-Johnson syndrome is an uncommon life threatening disease generally induced by drugs. Antibiotics, mainly sulphonamides, are the most involved drugs in Stevens-Johnson syndrome in children. Co-amoxiclav is a well tolerated antibiotic. It has never been reported to cause, lonely this syndrome in children. Herein, we report a co-amoxiclav-induced Stevens-Johnson syndrome occurring in an 18-month-old child. The diagnosis of SJS is often challenging in children and other possible diseases should be ruled out. The etiology of this syndrome is not yet fully understood. It is thought to be mediated by an immunologic mechanism. Management involves early identification, withdrawal of the culprit drug and rapid initiation of supportive therapies.

Human serum albumin (HSA) is the most abundant plasma protein in the human body. HSA plays an important role in drug transport and metabolism. This protein has a high affinity to a very wide range of materials, including metals such as Cu2+ and Zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. In this study, we investigated the effects of co-amoxiclav, as a drug which could be carried by this protein, on HSA structure and binding properties via spectroscopy and electrochemistry techniques. Based on this study, it was found that a therapeutic dose of co-amoxiclav as well as doses 4 to 8 folds higher than the therapeutic dose has no considerable effect on the HSA tertiary structure at 37(o)C. However, a dose 2 folds that of the therapeutic dose has a slight effect, but higher doses of the drug has a mild effect in pathological temperature (42(o)C). In addition, charge density of HSA surface is decreased at 42(o)C, compared to 37(o)C. Hence, this finding suggests a reduced role of HSA in regulation of osmotic pressure in the fever conditions, compared to the physiological conditions. Co-amoxiclav reduces the charge surface density of HSA at physiological and pathological temperatures and therefore alters its binding properties, which could be important in drug interference and complications.
