CASE REPORT: a 63-year old man, followed for a metastatic cardia cancer, develop a pericardial effusion with sign of pre-tamponade. A CT scanner suggests the presence of a gastro- esophageal-pericardial fistula. A surgical drainage brings a purulent fluid, infected by a polymicrobial flora. Despite early antibiotics with vancomycin and piperacillin-tazobactam, the patient dies five days after the drainage. DISCUSSION: purulent pericarditis associated with gastrointestinal neoplasia may be due to sepsis or a proximity invasion ...

Difficulties in the treatment of the resistant strains of Staphylococcus aureus, which is a frequent cause of nosocomial infections in paediatric patients, has prompted this research to empower the usage of various combinations of penicillin. During the study period 17,452 clinical samples were processed for culture. The positive cultures yielded 564 strains of S. aureus. Out of these, 362 (64.2%) isolates were found to be methicillin sensitive S. aureus (MSSA) and 202 (35.8%) methicillin resistant S. aureus (MRSA)...

Imipenem-cilastatin and piperacillin-tazobactam are two antibiotics with broad antimicrobial coverage. Besides the many well established adverse effects of these drugs, there have been few case reports of hypokalemia. Here we present an interesting case of resistant hypokalemia caused by these drugs leading to Torsades de Pointes which has never been reported in the past. Hypokalemia resolved with discontinuation of piperacillin.

A 28-year-old Filipino male was admitted due to high-grade fevers and dyspnea on a background of chronic cough and weight loss. Due to clinical and echocardiographic signs of cardiac tamponade, emergency pericardiocentesis was performed on his first hospital day. Five days after, chest radiographs showed new pockets of radiolucency within the cardiac shadow, indicative of pneumopericardium. On repeat echo, air microbubbles admixed with loculated effusion were visualized in the anterior pericardial space. Constrictive physiology was also supported by a thickened pericardium, septal bounce, exaggerated respiratory variation in AV valve inflow, and IVC plethora...

INTRODUCTION: In the structure of tuberculosis morbidity, urogenital tuberculosis (UGT) ranks second or third only to pulmonary tuberculosis. Every fourth patient has the stage of cavern formation at first presentation. Seventy five percent of nephrotuberculosis cases co-occur with nonspecific pyelonephritis, which excludes "sterile pyuria". We aimed to determine the microbial spectrum of urine and gonadal appendages in patients with suspected UGT and to investigate the susceptibility of the isolated microorganisms to the main antibacterial drugs...

BACKGROUND: Compared to developed countries, the use of antimicrobials in Egypt is less regulated and is available over the counter without the need for prescriptions. The impact of such policy on antimicrobial resistance has not been studied. This study aimed to determine the prevalence of early and late onset sepsis, and the frequency of antimicrobial resistance in a major referral neonatal intensive care unit (NICU). METHODS: The study included all neonates admitted to the NICU over a 12-month period...

The lack of new antibiotics prompted the investigation of the combination of two existing agents cefepime, a broad-spectrum cephalosporin and tazobactam to broaden its efficacy against extended-spectrum beta-lactamase producing Enterobacteriaceae. We determined the pharmacokinetic and pharmacodynamic properties of the combination in a murine neutropenic thigh model in order to establishing its exposure- response relationships (ERR). The PK of cefepime was determined for five doses; that of tazobactam was determined in earlier studies (Melchers et al Antimicrob...

Complicated skin and soft tissue infections (cSSTIs) are skin and soft tissue infections (SSTIs) that involve deep soft tissue. cSSTIs often require surgical intervention and/or hospitalization. cSSTIs are associated with significant mortality and morbidity, and carry a significant burden on health care systems. Piperacillin/tazobactam has been regarded as a standard treatment for cSSTIs because of its antibiotic spectrum, safety and clinical efficacy. Several antibiotics, as compared to piperacillin/tazobactam, have been evaluated in the treatment of cSSTIs...

Pseudomonas aeruginosa is the leading cause of pneumonia in intensive care units (ICUs), with multidrug-resistant (MDR) strains posing a serious threat. The aim of this study was to assess the clinical relevance of MDR Pseudomonas isolates in respiratory clinical specimens. A 5-year retrospective observational study in four medical-surgical ICUs from a referral hospital was carried out. Of 5667 adults admitted to the ICU, 69 had MDR-PA in respiratory samples: 31 were identified as having pneumonia (HAP/VAP): 21 ventilator-associated pneumonia (VAP) and ten hospital-acquired pneumonia (HAP)...

Recent findings have identified K. pneumoniae strains that are pan-β-lactam-susceptible (PBL-S), but piperacillin-tazobactam-resistant (TZP-R) in vitro We assessed the efficacy of a humanized exposure of TZP against 12 TZP-R/PBL-S K. pneumoniae isolates in an immunocompromised murine lung infection model. Discordance between the in vitro resistance profile and the in vivo efficacy of human simulated TZP exposures against this phenotypic profile was observed. Additional studies are required to define the clinical implications these TZP-R/PBL-S strains...
