Ciprofloxacin, a recently released oral fluorinated quinolone structurally related to nalidixic acid, joins norfloxacin as the second drug of this class to be released. Ciprofloxacin has a wide spectrum of antimicrobial activity and importantly demonstrates little cross resistance to non-quinolone drug classes (e.g. ureidopenicillins, cephalosporins, monobactams, carbapenems, aminoglycosides). Unlike other antibacterial classes such as the beta-lactams or aminoglycosides, ciprofloxacin does not suffer from transferable plasmid-mediated (i.e. R-factor) antibiotic resistance. Against gram-positive (including penicillin-resistant and methicillin-resistant staphylococci aureus) and gram-negative aerobic bacteria including Pseudomonas aeruginosa, ciprofloxacin demonstrates excellent activity. Ciprofloxacin is inactive against Trichomonas sp., treponemes, and fungi and anaerobes are considered resistant. Ciprofloxacin is rapidly absorbed from the gastrointestinal tract (i.e. 70-80% bioavailable), demonstrates extensive extravascular distribution, and its 3.5-5 hour half-life allows twice daily dosing. The bacteriologic and clinical efficacy of oral ciprofloxacin was shown to be comparable to third generation cephalosporins or aminoglycosides for osteomyelitis, cefotaxime for skin structure infections, and to a combination of tobramycin with azlocillin for pulmonary exacerbation of cystic fibrosis. Adverse events associated with ciprofloxacin are related mostly to gastrointestinal disturbance and consist of nausea/vomiting or diarrhea. Concomitant administration of ciprofloxacin and theophylline may lead to decreased theophylline clearance and necessitates periodic measurements of theophylline levels to avoid toxic levels. Treatment with oral ciprofloxacin should offer substantial cost savings over a variety of parenteral antimicrobial regimens (e.g. aminoglycoside + beta-lactams) for difficult to treat infections such as chronic pyelonephritis, osteomyelitis, and skin structure infections. Consideration of important precautions (e.g. contraindications, drug interactions) and potential disadvantages (e.g. emergence of resistance) must also guide the rational use of oral ciprofloxacin.

The tolerability of the 2 most frequently used carbapenems, imipenem/cilastatin and meropenem, is reviewed. Both of these drugs, but especially imipenem, are potentially neurotoxic and may cause seizures if overdosed relative to renal function and/or bodyweight. The therapeutic margin is considerably narrower with imipenem/cilastatin which cannot be given at doses required for treatment of bacterial meningitis. Meropenem on the other hand, is considerably less prone to cause seizures and its tolerability and efficacy are well documented in 3 relatively large, controlled studies in adults and children with meningitis. They showed that meropenem was as effective and well tolerated as cefotaxime or ceftriaxone. Another potential advantage of meropenem over imipenem/cilastatin is that it can be given intravenously at a high rate without increased risk of nausea or vomiting. An obvious reason for using a carbapenem instead of a cephalosporin for empirical treatment of life-threatening infections is that both imipenem/cilastatin and meropenem have a broader spectrum of activity. They are also more resistant to hydrolysis by the most common beta-lactamases, including the class I cephalosporinase frequently produced by Enterobacter spp. and Pseudomonas spp. and the extended spectrum enzymes, now commonly found in Escherichia coli and Klebsiella spp.

Pyogenic liver abscess (PLA), a very uncommon liver disease in the normal pediatric group is often associated with immunocompromised conditions. Pseudomonas aeruginosa has long been regarded as a relatively rare pathogen of PLA, especially in patients without underlying problems. A previously healthy one-year-and-seven-month-old boy who had symptoms of fever, vomiting and diarrhea got a liver abscess at right hepatic lobe which was confirmed by abdominal ultrasound and computed tomography (CT) diagnoses. Ultrasound-guided percutaneous aspiration of liver abscess was done soon after the confirmation. The culture result of aspirate grew P. aeruginosa. The patient received a 4-week course of adequate antibiotics treatment after the aforementioned aspiration procedure. In addition, a series of ultrasounds were performed to follow the resolution of abscess during the treatment period. The immune function tests of the patient were within normal ranges. Finally, the lesion resolved completely without leaving any complication.

Cefditoren pivoxil, an oral third-generation cephalosporin, was approved by the Food and Drug Administration in September 2001. It has been used in Japan for several years. The greatest therapeutic potential of cefditoren appears to be its activity against gram-positive and gram-negative organisms causing respiratory tract infections and skin and skin-structure infections, such as Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella catarrhalis. Cefditoren is also effective against methicillin-susceptible strains of Staphylococcus aureus. Nevertheless, cefditoren has no activity against atypical pathogens, including Chlamydia pneumoniae, Mycoplasma pneumoniae, and Legionella sp. Moreover, cefditoren does not inhibit Pseudomonas aeruginosa or Bacteroides fragilis. In virtually all studies, cefditoren has compared favorably against other orally administered antibiotics used against the most commonly isolated respiratory tract pathogens. Its side effect profile includes diarrhea, nausea, vomiting, headache, and dyspepsia. Cefditoren is indicated for treatment of mild-to-moderate acute exacerbations of chronic bronchitis, pharyngitis-tonsillitis, and uncomplicated skin and skin-structure infections caused by susceptible strains of organisms in adults and adolescents (> or = 12 yrs of age). Based on its reported antimicrobial activity, cefditoren has potential for empiric management of most commonly encountered respiratory tract infections. Additional studies will further define its role in clinical practice.

Colistimethate sodium (Coly-Mycin) was used in the treatment of 17 patients: 13 had urinary tract infections (two of these had positive blood cultures), three had respiratory tract infections, and one patient had both urinary and respiratory tract infections. In nine of the 17 a foreign body-either a carcinoma, a catheter, or a stone-complicated the infection.The dosage used was 1.1-2.3 mg./lb./day with a maximum in one case of 2.4 g. given over an eight-day period. The organisms so treated included Pseudomonas, six; Aerobacter, six and E. coli, two. Both Pseudomonas and Aerobacter were encountered in three cases.On bacteriological grounds, six patients were cured, eight relapsed, and in three the infecting agent was replaced by another organism. The best responses were obtained in those patients with Pseudomonas infection. Side effects included nausea, vomiting, vertigo, paresthesias, and pain at the site of injection.Colistimethate sodium has a place in the treatment of Gram-negative infections excluding Proteus organisms.

Cefetamet pivoxil is an oral, third-generation cephalosporin whose broad spectrum of antibacterial activity and favorable pharmacokinetic profile make it particularly suitable for the treatment of a wide range of infectious diseases. Cefetamet has high in vitro activity against both gram-positive and gram-negative bacteria that cause a number of respiratory tract and urinary tract infections. These include penicillin-sensitive Streptococcus pneumoniae, Streptococcus spp, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli, Proteus spp., Klebsiella spp. and Neisseria gonorrhoeae. It is not active against staphylococci, enterococci, Pseudomonas spp. or Bacteroides fragilis but does inhibit most bile-sensitive (oral) Bacteroides spp. Animal toxicology studies indicate that neither cefetamet pivoxil nor the active compound cefetamet have significant teratogenic, mutagenic, photogenic or allergenic potential. Cefetamet is eliminated unchanged in the urine with a half-life of 2.2 h. Volume of distribution approximates the extracellular fluid space (0.3 1/kg), protein binding is minima (22%) and oral bioavailability of cefetamet pivoxil is approximately 50% when taken with food. No significant drug interactions have been noted to date. The efficacy and tolerability of cefetamet pivoxil have been evaluated in the treatment of gram-positive and gram-negative infections in almost 5,000 patients. In comparative studies, cefetamet pivoxil was at least as effective, and in many cases clinically superior, to most currently recommended antibiotics for the treatment of urinary tract infections including gonorrhea and complicated infections in high risk patients. Efficacy has also been demonstrated in acute exacerbations of chronic bronchitis, pneumonia and infections of the ear, nose and throat. Clinical trials have shown that a 7 day treatment period with cefetamet pivoxil is as effective as a 10 day course of phenoxymethylpenicillin in the treatment of pharyngotonsillitis. Cefetamet pivoxil has been well-tolerated in clinical trials with only 1.2% of patients on standard doses discontinuing therapy prematurely. The most common adverse effects are gastrointestinal (diarrhea, nausea, vomiting) which occur in less than 10% of patients. Many current antibiotic treatment regimens involve the administration of three or more daily doses. However, standard doses of cefetamet pivoxil 500 mg twice daily provide unbound plasma concentrations of cefetamet which generally exceed the MIC(90) for susceptible organisms throughout the dosing interval and have been demonstrated to be clinically effective. This should result in good compliance with therapy in out-patients. Dosing regimens for cefetamet pivoxil should be adjusted in patients with impaired renal function while standard doses can be given to elderly patients and those with liver disease. Standard doses in children are 10 mg/kg or alternatively, children may receive a dose reduced in proportion to the ratio of their body surface area to that of an adult.

The aims of this study were to assess epidemiological features, clinical outcomes, laboratory findings, causative organisms and treatment approach for continuous ambulatory peritoneal dialysis (CAPD) -related peritonitis cases. A total of 50 patients (35 male, 15 female; age range: 18-83 years, mean age: 49 +/-17 years) with CAPD related peritonitis treated in Infectious Diseases and Clinical Microbiology Department of Ankara Training and Research Hospital between February-July 2006 were enrolled into this study. Demographic characteristics, symptoms, physical examination findings and laboratory parameters of patients were recorded and evaluated at the baseline, 48 hours and at the end of treatment. Fifty six peritonitis episodes occurred during the study period, and overall incidence of peritonitis was calculated as 1.6 episodes/patient-year. The most common presenting symptoms were cloudiness of the peritoneal dialysis fluid (100%), abdominal pain (98%), nausea (74%) and vomiting (54%). Abdominal tenderness and rebaund (100%) were the most common physical examination findings. Increased levels of C-reactive protein, erythrocyte sedimentation rate and procalcitonin were detected in 88%, 94% and 42% of the patients, respectively. The mean white blood cell count of peritoneal dialysate fluids was 905/mm3 (170-17900/mm3) in 56 episodes. In direct microscopic examination of peritoneal fluid samples with Gram stain, positivity was detected in 10 (18%) of the attacks, in which eight yielded gram-positive cocci and two gram-negative bacilli. The rate of culture positivity was 74% in the peritonitis episodes, and no microorganism was isolated from the cultures of 26% of the episodes. The most frequently isolated microorganisms were coagulase-positive staphylococci, followed by Staphylococcus aureus (n:4) and E. coli (n:4) with the rates of 7% of each, Enterococcus spp. (n:3), Klebsiella spp. (n:3) and Pseudomonas spp. (n:3) with the rates of 5% of each, and Streptococcus spp. (n:1), diphtheroid bacillus (n:1) and Candida albicans (n:1) with the rates of 2% of each. Eightyfour percent of patients were successfully treated with intraperitoneal cefazolin and gentamicin empirically. Three of the patient's CAPD therapy was converted to hemodialysis, while two patients have died. As a result, since peritonitis is still the major complication of CAPD despite the technological developments, the informations about causative microorganisms and their antimicrobial susceptibilities would be helpful for the early and accurate treatment of peritonitis.

Pseudomonas stutzeri which is an aerobic, non-fermentative gram-negative bacillus frequently found in soil, water and hospital environment, rarely leads to serious community-acquired infections. In this report a case of community-acquired meningitis due to P. stutzeri was presented. A 73-years-old male patient was admitted to the emergency department with the complaints of nausea, vomiting, headache, dizziness, difficulties in walking and speaking and loss of consciousness. There was no history of an underlying disease or immunosuppression. Physical examination revealed nuchal rigidity, however, Kernig and Brudzinski signs were negative. The cerebrospinal fluid (CSF) analysis revealed 0.4 mg/dl glucose (simultaneous blood glucose 145 mg/dl), and 618 mg/dl protein and 640 leucocyte/mm3 (90% PMNL). No bacteria were detected in Gram stained and Ehrlich-Ziehl-Neelsen stained CSF smears. Upon the diagnosis of acute bacterial meningitis, treatment with ceftriaxone and ampicillin was initiated, however, the patient died after 16 hours of hospitalization. CSF culture yielded the growth of gram-negative oxidase-positive bacteria and the isolate was identified as P. stutzeri by Vitek-2 Compact system (bioMerieux, France). The isolate was found to be sensitive to piperacillin/tazobactam, amikacin, gentamycin, ceftazidime, cefepime, ciprofloxacin, imipenem and meropenem. Since the patient was lost due to acute respiratory and cardiac failure, it was not possible to change the therapy to agent specific therapy. In conclusion, it should always be kept in mind that uncommon agents could lead to community-acquired meningitis in elderly patients and empirical treatment protocols might fail in such cases resulting in high morbidity and mortality.

Reports of wild great ape fatalities have been very limited, and only two have described wild orangutan deaths. We found a wounded juvenile female Bornean orangutan on 7 October 2006 in the Danum Valley, Sabah, Malaysia, and observed the individual's behavior for 7 days until her death on 13 October 2006. The 5-6-year-old orangutan, which we had observed since 2004, was wounded in the left brachium, back, and right hand. The individual's behavior changed after injury; the mean nest-nest active time became significantly shorter than before injury (from 12 h 3 min to 9 h 33 min), the mean waking time became significantly later (0552-0629 hours) and the mean bedtime became significantly earlier (from 1747 to 1603 hours). In the activity budget, resting increased significantly from 28.0 to 53.3%. Traveling and feeding decreased significantly from 23.5 to 12.7% and from 45.6 to 32.8%, respectively. The rate of brachiation during traveling and nest making decreased, whereas ground activity increased from 0 to 9%. We observed one vomiting incident and four occurrences of watery diarrhea during the 7 days before the individual died. The results of an autopsy performed by a local veterinarian suggested that the cause of death was septicemia because of Pseudomonas aeruginosa infection of the severely contaminated wounds. The morphology and distribution of the wounds suggested they had been incurred during an attack by a large animal with fangs and/or claws. This juvenile female became independent of its mother at ~4-5 years of age, slightly earlier than average. This individual might have been vulnerable to predatory attack because of her small body size (~5 kg at death) and lack of the mother's protection.

A 21-year-old female patient was diagnosed with horseshoe kidney at the age of 10. She had been treated with peritoneal dialysis from 2005 to 2009, when she received kidney from a deceased donor. The posttransplant course was complicated by development of Pseudomonas aeruginosa and Candida sepsis. Reduced immunosuppression resulted in acute rejection, which demanded graphtectomy 2 months after transplantation. She restarted peritoneal dialysis for additional 2 years. In March 2011, she received her second transplant with excellent function. Nine months after the transplantation, she developed ascites, with early satiety and vomiting. MSCT revealed severe encapsulating sclerosing peritonitis. Her overall condition deteriorated, so she underwent adhesiolysis with resection of incarcerated terminal ileum. Due to acute allograft rejection, urgent graphtectomy was performed. Currently, she is receiving everolimus and dialysis successfully, with excellent overall status.
