Community-acquired pneumonia (CAP) in the elderly has increased as a consequence of an overall increase of the elderly population. A controversy about the aetiology and outcome of CAP in this population still exists and more epidemiological studies are needed. A prospective, 12-month, multicentre study was carried out to assess the clinical characteristics, aetiology, evolution and prognostic factors of elderly patients (> or = 65 yrs) admitted to hospital for CAP. The study included 503 patients (age 76 +/- 7 yrs). The clinical picture lasted < or = 5 days in 318 (63%) and the main clinical features were cough (n = 407, 81%) and fever (n = 380, 76%). Aetiological diagnosis was achieved in 199 (40%) cases, with a definite diagnosis obtained in 164 (33%). Of the 223 microorganisms isolated the main agents found were Streptococcus pneumoniae in 98 (49%) and Haemophilus influenzae in 27 (14%). A total of 53 patients died (11%) and the multivariate analysis showed the following factors of bad prognosis: previous bed confinement, alteration in mental status, absence of chills, plasma creatinine > or = 1.4 mg x dL(-1), oxygen tension in arterial blood/inspiratorv oxygen fraction ratio < 200 at the time of admission, and shock and renal failure during the evolution. The results of this study may aid in the management of empiric antibiotic treatment in elderly patients with community-acquired pneumonia and the patients who have a greater probability of bad evolution may be identified based on the risk factors.

The published literature on bacterial tracheitis is limited. We report the first multi-centre study of bacterial tracheitis together with a concise review of the literature. We conducted a retrospective study of cases admitted during the period 1993-2007 to 3 tertiary paediatric centres in the United Kingdom and 1 in Australia. A total of 34 cases were identified. 31 patients (91%) required intubation. Complications included cardiorespiratory arrest in 1, ARDS in 1, hypotension in 10, toxic shock syndrome in 1 and renal failure in 1 patient(s). Staphylococcus aureus was the most commonly implicated bacterial organism, isolated from the respiratory tract in 55.8% of the cases overall. Other pathogens commonly isolated from the respiratory tract included Streptococcus pyogenes (5.9%), Streptococcus pneumoniae (11.8%) and Haemophilus influenzae (11.8%). Viral coinfection was identified in 9 (31%) of the 29 cases in whom immunofluorescence testing was performed (influenza A in 4 cases; parainfluenza 1 in 2 cases; parainfluenza 3 in 2 cases; adenovirus in 1 case). The combined experience from 4 major paediatric intensive care units suggests that bacterial tracheitis remains a rare condition with an estimated incidence of approximately 0.1/100,000 children per year. Short-term complications were common but long-term sequelae were rare. There were no fatal outcomes, which contrasts with the high historical mortality rates and likely reflects improvements in intensive care management.

Haemophilus influenzae is a rarely reported cause of peritonitis in chronic ambulatory peritoneal dialysis (CAPD) patients. In this report, a peritonitis case due to H. influenzae in a 32-years-old female patient with end-stage renal failure receiving CAPD for 7 years, has been reported. The patient was admitted to our clinic with the complaints of nausea, vomiting, abdominal pain, and cloudy dialysate. She had diffuse abdominal tenderness, however, other systems and peritoneal catheter exit site were found to be normal in physical examination. White blood cell (WBC) count in peritoneal fluid was 1.500/mm3 with 90% neutrophils. Gram stain of the peritoneal fluid yielded moderate number of polymorphonuclear leucocytes but no microorganism. Empirical antibiotic therapy with vancomycin and amikacin was initiated intraperitoneally. Peritoneal fluid and blood cultures were performed using BacT/ALERT (bioMerieux, NC, USA) blood culture system. Although no growth was detected in the blood sample at the end of the 5 days, growth was observed in the peritoneal sample within 48 hours. Gram staining of the positive bottle revealed gram-negative coccobacilli. At the end of an overnight incubation period, the colonies, which grew on chocolate agar, were identified as H. influenzae by using API NH system (bioMerieux, NC, USA). The isolate was found to be beta-lactamase-negative. The antibiotic regimen was switched to cephazoline 2 g/day intraperitoneally. The patient rapidly recovered and the WBC count of the peritoneal effluent decreased to 70/mm3. The therapy was continued for 21 days and she was discharged. The peritoneal catheter was not removed. During 7 months after the therapy, peritonitis did not recur. In conclusion, H. influenzae should be kept in mind as a cause of peritonitis in CAPD patients even though it is an unusual agent and the infection may be successfully treated with intraperitoneal antibiotics without removal of peritoneal dialysis catheter.

Thrombotic microangiopathy (TMA) is a well-recognised complication following transplantation, often due to an underlying genetic predisposition, medications or rejection. The use of eculizumab in these settings has been previously described, but its role still remains to be clarified. A 45-year-old man, with a history of type 1 diabetes mellitus and subsequent end-stage kidney failure, presented for a simultaneous pancreas-kidney transplant. Immunologically, he was well matched with the donor, and he received standard induction immunosuppression including tacrolimus. His early transplant course was complicated by Haemophilus parainfluenzae paronychia and a Pseudomonas aeruginosa catheter-associated urinary tract infection. Within 1 week, he developed thrombotic microangiopathy with significant renal dysfunction and eventual dialysis dependence, without evidence of transplant rejection on biopsy. He was also noted to have antiphospholipid antibodies in moderate titres. The TMA did not resolve despite cessation of tacrolimus, and he was subsequently commenced on eculizumab. The patient achieved a partial remission from TMA, with ongoing biochemical evidence of haemolysis, although now with stable graft function, despite significant damage. His transplanted pancreas remained seemingly unaffected by TMA, and continues to function well. This case describes an unusual presentation of TMA post-transplantation and is the only described case of eculizumab use following pancreas-kidney transplant. It remains unclear in this case what the likely precipitant for TMA was, although it seems to be, at least in part, controlled by ongoing use of eculizumab, presumably by terminal complement inhibition.
