Achromobacter xylosoxidans (Alcali9,nes xylosoxidans subsp. xylosoxidans) is an aerobic gram·negative organism first described bl' Yabuuchi en Ohyama in 1971. Achromobacter is aften found in aqueous environments and has been isolated in duck pond water, weil-water, swimming pools, distiJled water and chlorhexidin solutions [I-Z). It is resistam te most amimicrobial agents and causes infections in immunocompromised patients with underll'ing diseases like diabetes and malignancy (3). The most frequently encoumered infections are catheter-associated bacteremia and pneumonia, however surgical wound infections, meningitis, biliary tract infections , urinary tract infections and osteomyelitis have also been des cri bed [4J·

Some weeks later th e patient developed high fever and blood cultures we re taken which yielded Athromobacter xylosoxidans subsp. xylosoxidans. Trimethoprim­ sulfamethoxazol therapy was statted based on susceptibiliry results of survei llance culrures. All intravasc ular lines were removed. Culrures were raken from the intravascular lines, sputum , urine and a decubital uker at the sacral region. Arhromobacter was isolated from the decubiral uJeer and from the tip of a peripheral

This case report shows that rirual washing with weil-water mal' lead ra Achromobacter xylosoxidans bacterem ia and sepsis.

We noted that during visiting hoUts the famil)' was ritual washing the patient with weil-water from the parienrs hometown in Indonesia. In retrospect these washings had already statted at the universiry hospita!. Consent was obtained from the family to culrure thewater the)' used for these ritual washings. From this water Achromobacter xylosoxidans subsp. xy losoxidans was isolated. I6S rRNA sequenrion analysis was performed ofboth the Arhromobacter xylosoxidans strain isolated from the bl ood and the strain isolated from the weil-water and it showed 100% homology. Our hypothesis that the patient was colonized with Arhromobacter xylosoxidans due to ritual washin gs by relatives with conraminated water leading to bacteremia and recurrent sepsis seems hereb)' proven. Bath hospitals did not reveal culrures positive

Introduction . Clozapine is frequently prescribed for therapy resistant psychoses in schi zop hren iaand low incidence oftardive dyskinesia and extrapyramidal side effects [1] . Clozapine depends malnly on cytochrome P4s0 IA2 (CYPIA2) for its metabolic clearance. CYPIA2 is inducible b)' smoking, and lower plasma concentrations of c10zapine are measured in smokers than in nonsmokers [2-3]. Smoking cessarion may increase c10zapine drug levels. After ciproftoxacin use also increased drug levels up to 3'% have been described due to inhibirion ofCYFrA2 [4]. We report a case of reversible cardiomyopath)' due to c10zapine in a schizophrenic pari ent. Case. A forry-)'ear-old schizophrenic patient presented with fever, farigue and dry cough for prolonged time. No prior ca rd iac history was known. Due to discomfott he quit heavy smoking two days earlier. He was on several psychiatric medications. Two months before ad miss ion c10zapine roomg bid was added. Seven days before admission c10zapine drug level s were normal i.e. 22 5 ~g/L (200-600 ~g/ L) . Physical examination revealed: temperarure 38.6 °C, heatt rate: 126 bpm, and blood press ure IOo/6smmHg. Cardiac and pulmonary auscultations were normal, Oxygen sarurario n was 950/0. Chest X-ral' revealed no abno rmalities. Laboratory findings showed: Hb 7.3 mmolil, MCV 76 ft, CR!' 179 mg/ L, CK 4s41U/L, Urea 10.6 mmolil and creatinine 122 mcmol/L. ECG showed supraventricular tachycardia. Spurum, blood and urine culrures were taken. Empirically, cefo taxim and ciproftoxacin we re prescribed for suspected CAP. Over 24 hours patient's condition deteriorated. Heatt rate increased to r60 bpm and bloo d pressure dropped to 90/60 mmH g. New findings were tachypnoea (301 min) and a dec rease in oxygen saturation (92%).Repeated chest X-ray showed no pul monary infiltrations, however heatt size had slightl)' increased. Patienr was admitted to the ICU, inrubated and tteated according the surviving sepsis guidelines for assumed pneumosepsis. One hour afrer ICU admission bradycard ia
