Aim: Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors. Methods: Fifty-two HCWs who work at intensive care unit (ICU), bronchoscopy unit, and chest diseases department were tested for LTBI using both tuberculin skin test (TST) and Quantiferon TB Gold in-tube test (QFT)...

Background: Data on MRSA prevalence in rehabilitation centers are sparse. Methods: We screened more than 18,000 patients with neurological, cardiac/pulmonary or orthopedic diagnoses treated in three German rehabilitation centers and documented potential risk factors in almost 1,500 of them. Results: 2.1% were MRSA positive (CI 1.9%-2.4%). Prevalence was higher in neurologic patients (3.7%) and lower in orthopedic patients (0.9%). While the overall MRSA situation was stable over two years, the weekly MRSA rate fluctuated strongly (0...

Background: Staff in children's hospitals may run an increased risk of cytomegalovirus (CMV) contact infection leading to a congenital CMV fetopathy during pregnancy. The main risk factor is close contact with inapparent carriers of CMV among infants (<3 years). We therefore examined CMV seroprevalence (SP) and possible risk factors for CMV infection among staff at a children's hospital. Method: In 2014, staff at a metropolitan children's hospital were offered a CMV antibody test in the context of occupational health screening...

Infection is a serious complication after implantation of total knee-prostheses. However, fungal infection is rarely found in periprosthetic joints, and in most reports, the infecting organism is a Candida species. This is a case report of infection after left knee total arthroplasty caused by Malassezia species. The patient is still undergoing antifungal therapy with voriconazole and is still being followed-up. To the authors' knowledge, the present case is the first report of Malassezia species in a patient after total knee arthroplasty...

AIM: The antimicrobial activity of cold atmospheric pressure plasma (CAP), also called tissue tolerable plasma (TTP), could be a promising option to eradicate methicillin-sensitive as well as methicillin-resistant Staphylococcus aureus strains, which often colonize chronic wounds. Currently, the influence of CAP on the susceptibility of S. aureus to antibiotics is scarcely known, but could be important for treatment of wounds. Therefore, the aim of this study was to investigate whether CAP has an impact on the susceptibility of different S...

INTRODUCTION: The refugee crisis is a great challenge to the social and healthcare system in European countries, especially in Germany. An abundance of data has been published on the refugees' health problems (infections as well as physical diseases and psychiatric problems) and their prevention (i.e., sanitary and vaccination programs). However, data on prevalences of multidrug-resistant organisms (MDRO) in refugees are scarce, although it is known that most refugees are from or travelled through countries with high prevalences of MDRO...

INTRODUCTION: Urinary tract infections range among the most frequent infections not only in hospital patients but also in residents of long-term care facilities for the elderly. Urinary catheters are the greatest risk factor for urinary tract infections. In the guidance paper on the "prevention of infections in nursing homes" (2005) as well as in the updated recommendations for the "prevention and control of catheter-associated urinary tract infections" (2015), the Commission for Hospital Hygiene and Infection Prevention (KRINKO) has recommended adequate preventive measures...

Syphilis is considered as one of the most devastating sexually transmitted diseases in human history. Based on historical records, the "Böse Blattern" (German for "Evil Pocks") spread through Europe after 1495 and shared symptoms with what we know today as syphilis. Many cities took measures to protect their population. Here, transliterations of archival documents from the 15(th) and 16(th) century (provided in the appendix) are used to trace the steps taken by the governing authorities in Zurich to deal with this emerging infectious disease...

Pediatric patients receiving conventional chemotherapy for malignant disease face an increased risk of bloodstream infection (BSI). Since BSI may represent an acute life-threatening event in patients with profound immunosuppression, and show further negative impact on quality of life and anticancer treatment, the prevention of BSI is of paramount importance to improve and guarantee patients' safety during intensive treatment. The great majority of all pediatric cancer patients (about 85%) have a long-term central venous access catheter in use (type Broviac or Port; CVAD)...

BACKGROUND: Close contact with asymptomatic children younger than three years is a risk factor for a primary cytomegalovirus (CMV) infection. In pregnant women, such primary infection increases the risk of CMV-induced feto- or embryopathy. Daycare providers have therefore implemented working restrictions for pregnant daycare workers (DCWs) in accordance with legislation and guidelines for maternity protection. However, little is known about the infection risk for DCWs. We therefore compared the prevalence of CMV antibodies of pregnant DCWs to that of female blood donors (BDs)...

In 2015, most of the refugees arriving in Germany originated from countries with poor hygienic and sanitary conditions. Stool samples of 1,230 minor refugees unaccompanied by adults were investigated for possible parasites. Giardia lamblia was by far the most frequently detected parasite (n=165); all other parasites were considerably less frequent and encountered in the following order: Hymenolepis nana (n=23), Entamoeba histolytica (n=17), Trichuris trichiura (n=8), and Blastocystis hominis (n=1). Ascaris lumbricoides was not detected among any of the screened refugees...
