The consensus-based guideline "hand antisepsis and hand hygiene" for Germany has the following sections: Prevention of nosocomial infections by hygienic hand antisepsis, prevention of surgical site infections by surgical hand antisepsis, infection prevention in the community by hand antisepsis in epidemic or pandemic situations, hand washing, selection of alcohol-based hand rubs and wash lotions, medical gloves and protective gloves, preconditions for hand hygiene, skin protection and skin care, quality assurance of the implementation of hand hygiene measures and legal aspects. The guideline was developed by the German Society for Hospital Hygiene in cooperation with 22 professional societies, 2 professional organizations, the German Care Council, the Federal Working Group for Self-Help of People with Disabilities and Chronic Illness and their Family Members, the General Accident Insurance Institution Austria and the German-speaking Interest Group of Infection Prevention Experts and Hospital Hygiene Consultants.

Ninety-eight PCCT examinations using either IQL70 (n = 31), IQL60 (n = 31) or IQL50 (n = 36) were retrospectively included. Parameters for the radiation dose and the quantitative image quality were analyzed.

Standard CT scans were used as a reference (S40, Somatom Sensation 40, Siemens Healthineers). Sixty-three patients, who underwent CT scans between August and December 2021, were retrospectively enrolled.

Because of the rising prevalence of antimicrobial resistance, urinalysis should always include urine culture and a resistogram in order to avoid an unspecific selection and overuse of antibiotics. Prevention of recurrent UTI must first of all rule out predisposing uropathogenic conditions.

Methods: General recommendations to reduce rUTIs lower the recurrence rate by up to approximately two thirds.
Nosocomial infections (NI) may be a serious and mostly avoidable consequence of medical procedures and often cause a significant aggravation of the patients underlying disease. Following surgical site infections, urinary tract infections (UTI) represent the second most common fraction of NIs (22.4%) in Germany and contribute to approximately 155,000 nosocomial UTIs (nUTI) every year.

Mostly young and, to some extent, postmenopausal women are affected by recurrent UTI (rUTI) defined as ≥3 UTI/year or ≥2 UTI/half year. In contrast, rUTI is rare in healthy men.

The secondary tumors up to 2009 were registered as well and related to the numbers of the different forms of urinary diversions resulting in tumor prevalences.

In 97 patients who underwent radical cystectomy for bladder cancer, 34 of whom received cisplatin-based chemotherapy, MT expression was evaluated immunohistochemically. Results were correlated with histopathologic data, survival rates, and outcome of chemotherapy.

The CT scan of the abdomen showed a horseshoe kidney with extensive stone formation in both kidneys and the urinary bladder. A massively calcified double pigtail ureteral stent could also be seen in the left upper urinary tract.

The anamnesis should also focus on factors that influence the natural flora (sexual intercourse, hygiene) but additionally include preceding antibiotic treatment and diseases that affect the immune status (diabetes mellitus). Urinalysis is the principal examination among the laboratory diagnostic procedures.

Here, we clearly identify the human organic cation transporter 2 (hOCT2) as the critical transporter for cis-platin nephrotoxicity in isolated human proximal tubules and offer a potential mechanism for reducing nephrotoxicity in clinical practice. Interaction of cis-platin with hOCT2 in kidney or hOCT1 in liver was investigated with the fluorescent cation 4-[4-(dimethyl-amino)styril]-methylpyridinium in stably transfected HEK293 cells and for the first time in tissues physiologically expressing these transporters, human proximal tubules, and human hepatocyte couplets.

Hormone-refractory prostate cancer is diagnosed with increasing incidence and has become a growing challenge for urologists. The improved understanding of the tumor biological mechanisms of the hormone-refractory state has led to innovative therapeutic developments in the field of hormonal and cytotoxic therapies. Recently, two large randomized Phase III trials with docetaxel-based chemotherapy were able to show prolonged survival and a positive influence on pain and quality of life, establishing a new standard of care for these patients.

The obstruction of the urinary flow may be acute or chronic, partial or complete, unilateral or bilateral, and may occur at any site of the urinary tract. The major causes of urinary tract obstruction vary with the age of the patient.

From 153 consecutive patients who had undergone radical cystectomy for bladder cancer, tumour tissue was analysed for Her2/neu amplification by fluorescent in situ hybridisation and for Her2/neu and Cox-2 protein expression by immunohistochemistry. Results were correlated with clinical data and survival times.
