-associated proctitis and ileitis mimicking Crohn's disease-A case report.

We report about a proctitis and ileitis terminalis, leading to the misdiagnosis of Chron's disease, in a male patient who has sex with men. Molecular multiplex analysis identified as the underlying cause. We provide diagnostic images, clues and pitfalls for diagnosis of associated proctitis.

Neutrophil-Specific Knockdown of β2 Integrins Impairs Antifungal Effector Functions and Aggravates the Course of Invasive Pulmonal Aspergillosis.

β2-integrins are heterodimeric surface receptors that are expressed specifically by leukocytes and consist of a variable α (CD11a-d) and a common β-subunit (CD18). Functional impairment of CD18, which causes leukocyte adhesion deficiency type-1 results in an immunocompromised state characterized by severe infections, such as invasive pulmonary aspergillosis (IPA). The underlying immune defects have largely been attributed to an impaired migratory and phagocytic activity of polymorphonuclear granulocytes (PMN).

German Multicenter Study Analyzing Antimicrobial Activity of Ceftazidime-Avibactam of Clinical Meropenem-Resistant Isolates Using a Commercially Available Broth Microdilution Assay.

Multidrug resistance is an emerging healthcare issue, especially concerning Pseudomonas aeruginosa. In this multicenter study, P. aeruginosa isolates with resistance against meropenem detected by routine methods were collected and tested for carbapenemase production and susceptibility against ceftazidime-avibactam.

Characteristics of bacterial infections and prevalence of multidrug-resistant bacteria in hospitalized patients with liver cirrhosis in Germany.

Introduction And Objectives: Bacterial infections are associated with a dismal prognosis in patients with liver cirrhosis. Data on their prevalence and the associated pathogen spectra in Germany are scarce. This study aimed to evaluate the impact of bacterial infections on mortality in hospitalized patients with liver cirrhosis and to analyze the prevalence of multidrug-resistant (MDR) bacteria in a German tertiary care center.

Lethal systemic and brain infection caused by algae in a patient with acute myeloid leukemia.

Systemic protothecosis is an exceptionally rare cause of sepsis with few available therapeutic options. Here, we report on a female patient with newly diagnosed acute myeloid leukemia who died after start of chemotherapy due to a severe septic shock caused by a disseminated systemic infection with including encephalitis.

Clarithromycin impairs tissue-resident memory and Th17 responses to macrolide-resistant Streptococcus pneumoniae infections.

The increasing prevalence of antimicrobial resistance in pathogens is a growing public health concern, with the potential to compromise the success of infectious disease treatments in the future. Particularly, the number of infections by macrolide antibiotics-resistant Streptococcus pneumoniae is increasing. We show here that Clarithromycin impairs both the frequencies and number of interleukin (IL)-17 producing T helper (Th) 17 cells within the lungs of mice infected with a macrolide-resistant S.

[Results of multimodal treatment of hepatic echinococcosis].

Background: Echinococcosis is a rare parasitosis in Germany for which the World Health Organization recommends stage-specific treatment strategies.

Objective: The aim of this study was to analyze the treatment results of patients with hepatic echinococcosis at a German center of excellence for liver surgery.

Methods: Patients who underwent surgery for hepatic echinococcosis between 2009 and 2018 at the University Hospital of Mainz (UMM) were included in this follow-up examination.

Mitral Valve Endocarditis-Related Stroke: A Case Report and Literature Review.

is a rare causative pathogen of infective endocarditis that results in a high risk of embolic events. The mortality rate for endocarditis is high. Old age and underlying urologic conditions are the best-known risk factors for infection.

Improvement of a Clinical Score for Necrotizing Fasciitis: 'Pain Out of Proportion' and High CRP Levels Aid the Diagnosis.

Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.

Phase I clinical trial of mixed bacterial vaccine (Coley's toxins) in patients with NY-ESO-1 expressing cancers: immunological effects and clinical activity.

Purpose: Mixed bacterial vaccine (MBV, Coley's toxins) is a historical, vaguely defined preparation of heat-inactivated Streptococcus pyogenes and Serratia marcescens used as nonspecific immunotherapy in the treatment of cancer. The mechanism of action is suspected to have an immunologic basis, yet it is poorly defined up to now. We developed a new, biochemically well defined and current good manufacturing practice-compliant MBV preparation, which has been investigated in patients with NY-ESO-1 expressing cancers.

Use of quantitative microbiological analyses to trace origin of contamination of parenteral nutrition solutions.

In the summer of 2010, parenteral nutrition (PN) admixtures were administered to neonates in the Pediatric Department of the University Medical Center Mainz that provoked severe clinical sequelae. Contamination of a dummy infusion with Enterobacter cloacae and Escherichia hermannii was detected on the day of the incident, and the same isolates were subsequently grown from all PN admixtures as well as from the parent amino acid solution from which the admixtures had been prepared. Quantitative microbiological analyses paired with the determination of endotoxin concentrations enabled the conclusion to be reached that the amino acid solution had represented the primary source of contamination, which must have occurred in the distant past and may have derived from passage of the bacteria through a crack in the glass container.

Is cell salvage safe in liver resection? A pilot study.

Study Objective: To investigate the quality of cell salvaged (CS) blood in patients undergoing hemihepatectomy (study group) and compare it with CS-blood from aortic surgery (control group).

Design: Observational study.

Setting: Operating room in a university hospital.

Eosinophilic meningitis due to Angiostrongylus cantonensis in Germany.

We report a case of eosinophilic meningitis due to Angiostrongylus cantonensis in a patient who returned from Thailand. The presence of a compatible epidemiologic history and eosinophilia in cerebrospinal fluid (CSF) lead to the diagnosis, which was confirmed by detection of specific antibodies. After treatment with albendazole and corticosteroids he recovered completely.

Thymidine-dependent Staphylococcus aureus small-colony variants: human pathogens that are relevant not only in cases of cystic fibrosis lung disease.

We report the isolation of thymidine-dependent small-colony variants (TD-SCVs) of Staphylococcus aureus from unusual infection sites of patients with chronic soft tissue infection, tympanitis, bronchitis, peritonitis, and septicemia. Furthermore, we provide evidence that the essential growth factor for TD-SCVs, i.e.

Actinomycosis of the jaws--histopathological study of 45 patients shows significant involvement in bisphosphonate-associated osteonecrosis and infected osteoradionecrosis.

Actinomycosis of the jaws is a rare disease, which has been recently described in patients with infected osteoradionecrosis (IORN) and bisphosphonate-associated osteonecrosis (BON). We investigated our archive material for Actinomycosis of the jaws with special regard to underlying disease. Out of a total number of 45 patients with Actinomycosis, 43 (93.

Diagnosing Helicobacter pylori in vivo by confocal laser endoscopy.

Background & Aims: Confocal laser endomicroscopy enables subsurface microscopic imaging of living tissue during ongoing endoscopy. This case report describes the in vivo detection of Helicobacter pylori by endomicroscopy.

Methods: Endomicroscopy (Pentax, Tokyo, EC-3870CIFK) was performed by using two different contrast stains: Topical Acriflavine in addition to intravenously applied fluorescein netted the surface and allowed identification of focal accumulation of Helicobacter pylori at the surface and in deeper layer of the gastric epithelium.
