We present an interesting case of cutaneousMycobacterium chelonae in a 95-year-old woman.The lesion in question was localized to her rightarm; subsequent biopsy and culture studies wereconsistent with a mycobacterial infection. Historically,these infections are treated based on the immunologicstate of the patient. In this case, taking into accountthe age of our otherwise immunocompetent patient,a course of oral antibiotics was initiated. The patientwas unable to tolerate any oral regimens for longerthan several weeks...

Patients surgically treated for infection after extremity fractures are typically discharged with a 6- to 12-week antibiotic regimen. Intravenous (IV) antibiotics are associated with significant cost and potential complications of deep vein thrombosis, line clotting, and sepsis. Many of the pathogens that cause musculoskeletal infection have both oral (PO) and IV antibiotic options with adequate bioavailability and antibacterial effect, yet IV antibiotics remain the standard of care absent evidence that PO options are clinically as efficacious...

OBJECTIVES: Helicobacter pylori is associated with peptic ulcers and gastric cancer and its eradication aims to prevent these conditions. The recommended eradication regimen is triple therapy, consisting of a proton-pump inhibitor in combination with clarithromycin and amoxicillin or metronidazole for 7 days. Yet, other antibiotic regimens are sometimes prescribed. We aimed to assess the use of eradication therapy for H. pylori in the Swedish population during the last decade. MATERIALS AND METHODS: This population-based study used data from the Swedish Prescribed Drug Register...

BACKGROUND AND AIM: Antibiotics have many beneficial effects but their uncontrolled use may lead to increased risk of serious diseases in the future. Our hypothesis is that an early antibiotic exposition may affect immune system by altering gut microbiota. Therefore, the aim of the study was to determine the effect of penicillin treatment on gut microorganisms and immune system of mice. METHODS: 21-days old C57BL6/J/cmdb male mice were treated with low-dose of penicillin (study group) or water only (control group) for 4 weeks...

PURPOSE: Preoperative antibiosis contributes up to one third of total antibiotic use in major hospitals. Choice of antibiotic is not uniformly standardized, and polypharmacy regimens may be used without knowing the effect on rates of surgical site infection, nonsurgical infections, or antibiotic resistance. Careful examination of trends in surgical prophylaxis is warranted. In this study, we aimed to examine our institution's experience with vagus nerve stimulator (VNS) implantation, focusing on association between perioperative antibiotic practices and postoperative infectious outcomes...

BACKGROUND: Port-site infection (PSI) is a prevailing, chronic, nagging, treatment refractory complication of laparoscopic surgery (LS). It neutralizes the advantages of minimally invasive surgery and increases morbidity, treatment cost of patient, leading to loss of confidence on operating surgeon. PSIs are preventable with appropriate preoperative, intraoperative, and postoperative measures. Atypical mycobacterium is most commonly associated with nonhealing postlaparoscopic wound infections, causing outbreaks or sporadic cases worldwide...

The authors report the case of a 5-year-old boy in whom extraneural metastases developed 5 years after he underwent an occipitocervical fusion and transoral approach to treat a clival chordoma without local recurrence. Following primary resection, the patient's postoperative course was complicated by recurrent meningitis secondary to CSF leak, which responded to antibiotics, and communicating hydrocephalus, for which a ventriculoperitoneal shunt was placed. The patient then underwent postoperative proton beam radiotherapy...

Patients with acute leukemia are susceptible to chemotherapy-induced severe myelosuppression, and therefore are at a high risk for febrile neutropenia (FN). In such cases, the use of broad-spectrum antibiotics such as fourth-generation cephalosporins and carbapenems is recommended as first-line antimicrobial treatment; however, the effectiveness of these agents in patients with acute myeloid leukemia (AML) has not been investigated in detail. We retrospectively examined and evaluated the effectiveness of first-line antibiotic treatment regimens for chemotherapy-induced FN in patients with AML in Japanese Red Cross Nagoya Daiichi Hospital...

Importance: Elevated body mass index (BMI) has been proposed as a risk factor for morbidity and mortality among patients undergoing surgery. Conversely, an elevated BMI may confer a protective effect on perioperative morbidity. Objective: To examine whether an elevated BMI is an independent risk factor for perioperative and postoperative infectious complications after free tissue transfer in head and neck reconstructive surgery. Design, Setting, and Participants: This cohort study included patients undergoing major head and neck surgery requiring free tissue transfer at a tertiary care center...

BACKGROUND: The mainstay of periodontal therapy is mechanical removal of subgingival plaque. There is considerable interest in supplementing it with the use of antibiotics and antiseptics. Many drawbacks are associated with these adjunctive pharmacological regimens such as development of resistance to antibiotics and disruption of microflora of the gastrointestinal tract. Hence, alternate means of killing subgingival bacteria are clearly desirable. One such method is the use of laser...

In 2008, a clinical practice guideline (CPG) was developed for the prevention of infections among combat casualties and was later revised in 2011. We evaluated utilization of antimicrobials within 48 hours following injury in the combat zone over a 5-year period (June 2009 through May 2014) with regard to number of regimens, type of antimicrobial, and adherence to the 2011 CPG. The study population consisted of 5,196 wounded military personnel. Open fractures and skin and soft-tissue injuries were the most frequent injuries...

Physiologically-based pharmacokinetic (PBPK) modeling is a powerful tool used to characterize maturational changes in drug disposition to inform dosing across childhood; however, its use is limited in pediatric drug development. Access to pediatric pharmacokinetic data is a barrier to widespread application of this model, which impedes its development and optimization. To support the development of a pediatric PBPK model, we sought to leverage opportunistically-collected plasma concentrations of the commonly used antibiotic clindamycin...

BACKGROUND: Prompt therapy with high-dose intravenous benzylpenicillin for a prolonged period is critical for neurosyphilis patients to avoid irreversible sequelae. However, life-threatening neutropenia has been reported as a complication of prolonged therapy with high doses of benzylpenicillin when treating other diseases. This study aimed to investigate the incidence, presentation, management and prognosis of benzylpenicillin-induced neutropenia in treating neurosyphilis based on a large sample of syphilis patients in Shanghai...

We assessed if use of an online clinical decision support tool improved standardization and quality of care in hospitalized patients with lower extremity cellulitis (LEC). This was a 14-month preintervention and postintervention study of 85 LEC admissions. There was significantly higher usage of the online LEC care process model (CPM) in the postintervention phase (p < .001). There was a trend toward higher rates of appropriate antibiotic regimen in the postintervention group both initially and at discharge (p = ...

Pneumonia is considered as the main cause of abdominal pain in children whereas it presents mostly by respiratory symptoms in adults. Here we present a 71-year-old Iranian female who complained specifically of abdominal pain on admission to our emergency department. We had found nothing as an etiology in our first evaluations. After several hours chest pain was added to the symptoms and the following chest, X-Ray showed a consolidation in the right lung base. She was treated by pneumonia antibiotic regimen and discharged after seven days in a good clinical condition...

To combat the spread of antibiotic resistance, methods that quantitatively assess metabolism-inhibiting effects of drugs in a rapid and culture-independent manner are urgently needed. Here using four oral bacteria as models, we show that heavy water (D2O) based Single-cell Raman Microspectroscopy (D2O-Raman) can probe bacterial response to different drugs using the Raman shift at C-D (carbon-deuterium vibration) band in 2,040 to 2,300 cm-1 as a universal biomarker for metabolic activity at single bacterial cell resolution...

With the universal adoption of antibiotic prophylaxis prior to prostate biopsy, the current risk of post-biopsy infection (including sepsis) is <2%. Preoperative prophylactic antibiotic regimens can vary, and although fluoroquinolones have emerged as the standard of care, there is no universally agreed upon preoperative antibiotic regimen. Recently, an increase in the proportion of postoperative infections caused by fluoroquinolone-resistant Escherichia coli (as well as other Enterobacteriaceae) has led to the exploration of simple, practical, and cost-effective methods to minimize this postoperative infection risk...
