    Bacterial infections are common in cirrhotic patients with acute variceal bleeding, occurring in 20% within 48 h. Outcomes including early rebleeding and failure to control bleeding are strongly associated with bacterial infection. However, mortality from variceal bleeding is largely determined by the severity of liver disease. Besides a higher Child-Pugh score, patients with hepatocellular carcinoma are particularly susceptible to infections. Despite several hypotheses that include increased use of instruments, greater risk of aspiration pneumonia and higher bacterial translocation, it remains debatable whether variceal bleeding results in infection or vice versa but studies suggest that antibiotic prophylaxis prior to endoscopy and up to 8 h is useful in reducing bacteremia and spontaneous bacterial peritonitis. Aerobic gram negative bacilli of enteric origin are most commonly isolated from cultures, but more recently, gram positives and quinolone-resistant organisms are increasingly seen, even though their clinical significance is unclear. Fluoroquinolones (including ciprofloxacin and norfloxacin) used for short term (7 d) have the most robust evidence and are recommended in most expert guidelines. Short term intravenous cephalosporin (especially ceftriaxone), given in a hospital setting with prevalent quinolone-resistant organisms, has been shown in studies to be beneficial, particularly in high risk patients with advanced cirrhosis.

    BACKGROUND: Information on antiretroviral therapy (ART) use in HIV-infected children with severe malnutrition (SM) is lacking. We investigated long-term ART outcomes in this population.

    METHODS: Children enrolled in the TREAT Asia Pediatric HIV Observational Database who had SM (weight-for-height or body mass index-for-age Z score less than -3) at ART initiation were analyzed. Generalized estimating equations were used to investigate poor weight recovery (weight-for-age Z score less than -3) and poor CD4% recovery (CD4% <25), and competing risk regression was used to analyze mortality and toxicity-associated treatment modification.

    RESULTS: Three hundred fifty-five (11.9%) of 2993 children starting ART had SM. Their median weight-for-age Z score increased from -5.6 at ART initiation to -2.3 after 36 months. Not using trimethoprim-sulfamethoxazole prophylaxis at baseline was associated with poor weight recovery [odds ratio: 2.49 vs. using; 95% confidence interval (CI): 1.66-3.74; P < 0.001]. Median CD4% increased from 3.0 at ART initiation to 27.2 after 36 months, and 56 (15.3%) children died during follow-up. More profound SM was associated with poor CD4% recovery (odds ratio: 1.78 for Z score less than -4.5 vs. -3.5 to less than -3.0; 95% CI: 1.08-2.92; P = 0.023) and mortality (hazard ratio: 2.57 for Z score less than -4.5 vs. -3.5 to less than -3.0; 95% CI: 1.24-5.33; P = 0.011). Twenty-two toxicity-associated ART modifications occurred at a rate of 2.4 per 100 patient-years, and rates did not differ by malnutrition severity.

    CONCLUSION: Trimethoprim-sulfamethoxazole prophylaxis is important for the recovery of weight-for-age in severely malnourished children starting ART. The extent of SM does not impede weight-for-age recovery or antiretroviral tolerability, but CD4% response is compromised in children with a very low weight-for-height/body mass index-for-age Z score, which may contribute to their high rate of mortality.

    INTRODUCTION: Percutaneous endoscopic gastrostomy (PEG) placement in patients with ventriculo-peritoneal shunt (VPS) may be associated with complications. This study reports our experience of PEG in patients with VPS.

    MATERIALS AND METHODS: Consecutive patients undergoing PEG insertion in a gastroenterology unit over 18 month's period were retrospectively analyzed. All patients were evaluated by an attending gastroenterologist for fitness for procedure. Instructions were given for routine antibiotic prophylaxes before the procedure and continued for 48 hours. Patients were followed for immediate complications in particular, wound infection, signs of meningitis, deterioration in neurological state and shunt malfunction. Post discharge, patients were given routine follow-up for review.

    RESULTS: Of 86 patients who had PEG inserted during the study period, 14 had VPS including 2 of which had VPS after PEG. The main common indications for VPS were intracerebral bleed and head trauma and for PEG were requirement of long term enteral feeding. Twelve patients had PEG at a mean interval of 61 days (range 1-187 days) after VPS. Of these, eight received prophylactic antibiotic or were on antibiotic for other indications before PEG. Two patients developed mild PEG site infections within a week of insertions, including one patient who was not given antibiotic prophylaxis, both treated successfully with antibiotics. The latter patient developed worsening hydrocephalus secondary to VPS blockage. At a mean follow-up period was 140 days (range 20-570 days), there were no death or further complications encountered.

    CONCLUSIONS: Although safe in the majority of patients with VPS, PEG infection can lead to intracranial complications. We recommend antibiotic prophylaxis for VPS patients before PEG.

    Deep surgical site infection is a devastating consequence of total joint arthroplasty. The use of antibiotic impregnated bone cement is a well-accepted adjunct for treatment of established infection and prevention of deep orthopaedic infection. It allows local delivery of the antibiotic at the cement-bone interface and sustained release of antibiotic provides adequate antibiotic coverage after the wound closure. Preclinical testing, randomised and clinical trials indicate that the use of antibiotic-impregnated bone cement is a potentially effective strategy in reducing the risk of deep surgical site infection following total joint arthroplasty. The purpose of this study was to assess antibacterial activity of erythromycin and colistin impregnated bone cement against strains of organisms' representative of orthopaedic infections including Gram-positive and Gram-negative aerobic organisms: Staphylococcus aureus, coagulase-negative Staphylococci, Enterococcus sp., Proteus sp., Klebsiella sp., Pseudomonas sp., and Escherichia coli. Pre-blended Simplex P bone cement with the addition of erythromycin and colistin (Howemedica Inc) was mixed thoroughly with 20ml liquid under sterile conditions to produce uniform cylindrical discs with a diameter of 14mm and thickness of 2mm. 24-48 hour agar cultures of Staphylococcus aureus, coagulase-negative Staphylococci, Enterococcus sp.,Proteus sp., Klebsiella sp.,Pseudomonas sp., and Escherichia coli were used for the agar diffusion tests. The agar plates were streaked for confluent growth followed by application of erythromycin and colistin impregnated bone cement disc to each agar plate. The plates were incubated at 30 degrees C and examined at 24, 48, 72 hours, and four and five days after the preparation of the impregnated cement. The susceptibility of Staphylococcus aureus to the control discs was most clearly demonstrated showing a distinct zone of inhibition. The zone observed around coagulase-negative Staphylococci, Klebsiella sp., Pseudomonas sp., and Escherichia coli were also significant. However, there was no zone of inhibition or signs of antibacterial activity at the cemented surface were detected around discs with Enterococcus sp. and Proteus sp. The results showed that Simplex P bone cement with the addition of erythromycin and colistin was effective against most of the broad spectrum organisms encountered during total joint arthroplasty. The activity of Simplex P bone cement impregnated with erythromycin and colistin is mainly during the first 72 hours.

    Antibiotic-loaded bone cement has been used as prophylaxis against infection in total joint replacement surgery. Its effect on the mechanical strength of cement is a major concern as high dose of antibiotic was associated with a significant reduction in mechanical strength of bone cement. However, the cut-off antibiotic that weakens the mechanical strength of cement remains to be determined. This study was undertaken to observe the changes in the mechanical properties of bone cement with gradual increments of Cefuroxime antibiotic. Cefuroxime at different doses: 0, 1.5, 3.0 and 4.5gm were added to a packet of 40gm bone cement (Simplex P) and study samples were prepared by using third generation cementing technique. Mechanical impact, flexural and tensile strength were tested on each sample. Significant impact and tensile strength reduction were observed after addition of 4.5 gm of Cefuroxime. However, flexural strength was significantly reduced at a lower dose of 3.0 gm. The maximum dose of Cefuroxime to be safely added to 40mg Surgical Simplex P is 1.5gm when third generation cementing technique is used. Further study is needed to determine whether it is an effective dose as regards to microbiological parameters.

    The national clinical practice guideline has recommended that prophylactic antibiotic be given in orthopaedic surgery involving joint replacements and internal fixation of fractures. The aim of this study is to assess the current antibiotics prophylaxis practice in a state level hospital. One hundred and three patients (68 males, 35 females; mean age 41.6 +/- 22.2 years) undergoing internal fixation for closed fractures and joint replacement surgery were included in this prospective study. The choice of pre and post-operative antibiotics, their dosages and duration of administration were recorded. The pre-operative antibiotics were only deemed to have been given if it was documented in the case notes and in the case of post-operative antibiotics if it was signed on the drug chart. Eighty eight percent were given pre-operative prophylactic antibiotics and 92% were given post-operative antibiotics. For patients undergoing internal fixation of fractures, the most commonly used antibiotic for both pre and post-op is intravenous cefuroxime. For joint replacement surgery, the most commonly used antibiotic is intravenous cefoperazone. The duration or number of doses of post-operative antibiotics was highly variable. It was not stated in 56% of the post-operative instructions. Post-operative antibiotic was ordered for 48 hours or longer in 10%. In conclusion, prophylactic antibiotics appear to be widely practised. The first line antibiotics as recommended by the present guideline were not given in any of the patients. Second generation followed by third generation cephalosporins are the most popular antibiotics, with a trend towards using third generation cephalosporins in arthroplasty patients. Single dose prophylaxis was rarely practised.

    This prospective, randomised, controlled trial was performed to evaluate the effectiveness of single-dose antibiotic prophylaxis in decreasing the infectious morbidity following elective caesarean section. Two hundred women undergoing elective caesarean section were randomly assigned to receive either 1.2 g of Augmentin intravenously, or no treatment, just before the start of their caesarean section. The two groups of women were comparable in terms of patient characteristics and operation variables. The overall postoperative morbidity rate was 19% in the Augmentin treated group versus 38% in the group that received no prophylaxis (p < 0.01). The incidence of wound sepsis was 3% in the Augmentin group versus 13% in the control group (p < 0.01). The incidence of febrile morbidity with no identifiable cause was 8% in the Augmentin group versus 18% in the control group (p < 0.05). The duration of hospital stay was significantly shorter in the Augmentin group (p < 0.05). A single-dose of prophylactic Augmentin significantly reduced the postoperative morbidity and duration of hospital stay in women who underwent elective caesarean sections.

    BACKGROUND: Nasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery.

    OBJECTIVE: To evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery.

    METHODS: A pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22-item Sino-Nasal Outcome Test questionnaire and nasal endoscopy.

    RESULTS: Patients in the mupirocin nasal lavage group had lower nasal endoscopy scores post-operatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better Sino-Nasal Outcome Test scores at one month compared to the group without mupirocin.

    CONCLUSION: Nasal lavage with mupirocin seems to yield better outcomes regarding patients' symptoms and endoscopic findings.

    Surgical site infections are the most common nosocomial infection among surgical patients. Patients who experience surgical site infections are associated with prolonged hospital stay, rehospitalisation, increased morbidity and mortality, and costs. Consequently, surgical antimicrobial prophylaxis (SAP), which is a very brief course of antibiotic given just before the surgery, has been introduced to prevent the occurrence of surgical site infections. The efficacy of SAP depends on several factors, including selection of appropriate antibiotic, timing of administration, dosage, duration of prophylaxis and route of administration. In many institutions around the globe, evidence-based guidelines have been developed to advance the proper use of SAP. This paper aims to review the studies on surgeons' adherence to SAP guidelines and factors influencing their adherence. A wide variation of overall compliance towards SAP guidelines was noted, ranging from 0% to 71.9%. The misuses of prophylactic antibiotics are commonly seen, particularly inappropriate choice and prolonged duration of administration. Lack of awareness of the available SAP guidelines, influence of initial training, personal preference and influence from colleagues were among the factors which hindered the surgeons' adherence to SAP guidelines. Immediate actions are needed to improve the adherence rate as inappropriate use of SAP can lead to the emergence of a strain of resistant bacteria resulting in a number of costs to the healthcare system. Corrective measures to improve SAP adherence include development of guidelines, education and effective dissemination of guidelines to targeted surgeons and routine audit of antibiotic utilisation by a dedicated infection control team.

    Routine postoperative antibiotic prophylaxis is not recommended for third molar extractions. However, amoxicillin still continues to be used customarily in several clinical practices worldwide to prevent infections. A prospective cohort study was conducted in cohorts who underwent third molar extractions with (group EA, n = 20) or without (group E, n = 20) amoxicillin (250 mg three times daily for 5 days). Further, a control group without amoxicillin and extractions (group C, n = 17) was included. Salivary samples were collected at baseline, 1-, 2-, 3-, 4-weeks and 3 months to assess the bacterial shift and antibiotic resistance gene changes employing 16S rRNA gene sequencing (Illumina-Miseq) and quantitative polymerase chain reaction. A further 6-month follow-up was performed for groups E and EA. Seven operational taxonomic units reported a significant change from baseline to 3 months for group EA (adjusted p  0.05). In conclusion, the salivary microbiome is resilient to an antibiotic challenge by a low-dose regimen of amoxicillin. Further studies evaluating the effect of routinely used higher dose regimens of amoxicillin on gram-negative bacteria and antibiotic resistance genes are warranted.

    BACKGROUND: Inappropriate and excessive use of surgical antibiotic prophylaxis are associated with the emergence of antibiotic resistance. Antibiotic prophylaxis malpractices are common in obstetrics and gynecology settings and antibiotic stewardship is used to correct such malpractice.

    OBJECTIVE: To evaluate the impact of antibiotic stewardship interventions on compliance with surgical antibiotic prophylaxis practice in obstetrics and gynecology surgeries.

    METHOD: A prospective pre- and post-intervention study was conducted in two tertiary hospitals between May and December 2016. The duration of the each period was 3 months. Antibiotic stewardship interventions including development of a protocol, educational meeting and audit and feedback were implemented. Data were collected using the patient records and analyzed with SPSS version 23.

    RESULTS: A total of 226 and 238 surgical procedures were included in the pre- and post-intervention periods respectively. Age, length of stay and estimated blood loss were similar between the two groups. However, specialty and surgical procedures varied significantly. There was a significant increase in compliance with timing (from 14.2% to 43.3%) and duration (from 0% to 21.8%) of surgical antibiotic prophylaxis after the interventions. The interventions significantly reduced the prescription of third generation cephalosporin (-8.6%), redundant antibiotic (-19.1%), antibiotic utilization (-3.8 DDD/procedure) and cost of antibiotic prophylaxis (-$4.2/procedure). There was no significant difference in the rate of surgical site infection between the two periods. Post-intervention group (OR: 5.60; 95% CI: 3.31-9.47), elective surgery (OR: 4.62; 95% CI: 2.51-8.47) and hospital attended (OR: 9.89; 95% CI: 5.66-17.26) were significant predictors of compliance with timing while elective surgery (OR: 12.49; 95% CI: 2.85-54.71) and compliance with timing (OR: 58.55; 95% CI: 12.66-270.75) were significantly associated with compliance to duration of surgical antibiotic prophylaxis.

    CONCLUSION: The interventions improve compliance with surgical antibiotic prophylaxis and reduce antibiotic utilization and cost. However, there is opportunity for further improvement, particularly in non-elective surgical procedures.

    Urinary tract infections frequently affect pregnant mothers. This problem causes significant morbidity and healthcare expenditure. Three common clinical manifestations of UTIs in pregnancy are: asymptomatic bacteriuria, acute cystitis and acute pyelonephritis. Escherichia coli remains the most frequent organism isolated in UTIs. All pregnant mothers should be screened for UTIs in pregnancy and antibiotics should be commenced without delay. Urine culture and sensitivity is the gold standard in diagnosing UTIs. Without treatment, asymptomatic bacteriuria in pregnancy is associated with preterm delivery, intrauterine growth retardation, low birth weight, maternal hypertension, pre-eclampsia and anaemia. Acute pyelonephritis can lead to maternal sepsis. Recurrent UTIs in pregnancy require prophylactic antibiotic treatment.

    Leptospirosis is one of the most widespread re-emerging zoonoses in the world. Malaysia is known to
    be an endemic country for human leptospirosis, with a case fatality rate of 2.11%, and an average annual
    incidence rate of 7.80 cases per 100,000 individuals. This systematic review is conducted to determine
    the effectiveness of antibiotic prophylaxis for leptospirosis among the adult populations who are highly
    at risk of getting infected. A systematic search was performed for the relevant titles, abstracts and
    keywords on PubMed, Scopus, Cochrane and Google Scholar from inception to November 2017 based
    on the PICO strategy; which returned 126 studies. Screening of abstracts had shortlisted 19 studies and
    data extraction was conducted for 8 studies which had been accepted after review of the full text. For
    the evaluation of antibiotics prophylaxis effectiveness against leptospirosis, only trials and cohort studies
    with risk ratio (RR) were selected. The articles were analyzed from the viewpoint of the dosage, adverse
    effects, study settings and effectiveness of the antibiotic prophylaxis. Using fixed effects model, pooled
    RR showed protective association between antibiotic prophylaxis use against the incidence of
    leptospirosis (RR = 0.31; 95% CI: 0.20, 0.48). Antibiotic prophylaxis for leptospirosis had been shown
    to be effective in preventing the incidence of the disease among high-risk populations and carries
    minimal adverse effects. It is recommended that the practice of antibiotic prophylaxis for leptospirosis is
    included in the standard protocol for leptospirosis prevention among people at high-risk, including
    disaster response teams and patrons of eco-sports tourism activities; with the drug of choice being
    doxycycline, either as a single 200 mg dose or weekly dose of 200 mg for the duration of exposure,
    based on the setting, duration of event and resources available.

    Early and targeted antimicrobial therapy improves outcomes in patients with febrile neutropenia (FN). We evaluated the impact of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) on antimicrobial utilization in the management of FN. A cohort of patients with FN and hematological malignancy was identified. Cases (in whom FDG-PET was performed, n = 37) were compared with controls (in whom conventional investigations excluding FDG-PET were performed, n = 76). An underlying cause for FN was determined in 94.6% of cases, compared to 69.7% of controls. FDG-PET had a significant impact on antimicrobial utilization compared to conventional imaging (35.1% vs. 11.8%; p = 0.003), and was associated with shorter duration of liposomal amphotericin-B therapy for systemic fungal infection (median 4.0 days cases vs. 10.0 days controls; p = 0.001). Cases had a longer length of hospitalization (p = 0.016). In the management of patients with high-risk FN, FDG-PET improves diagnostic yield and allows rationalization of antifungal therapy. The impact upon healthcare costs associated with antimicrobial therapy for FN requires further evaluation.
