We compared intravenously administered ciprofloxacin with ceftazidime in a randomized, double-blind study. Patients received ciprofloxacin 200 mg intravenously every 12 hours or ceftazidime 2 g intravenously every eight hours, with placebo infusions to maintain blinding. Therapy with metronidazole was added for suspected or documented intra-abdominal infection. Thirty-two of the 57 ciprofloxacin-treated patients were evaluable for determination of efficacy and had 41 bacterial isolates from 34 sites. Thirty-six of the 56 ceftazidime patients were evaluable for determination of efficacy and had 41 bacterial isolates from 38 sites. Seven of 35 bacteremic patients had no identifiable primary focus. The most commonly isolated pathogens were Escherichia coli, Streptococcus pneumoniae, Staphylococcus aureus, and Klebsiella pneumoniae. Cure rates and bacteriologic eradication rates were comparable. Nine patients did not improve. Patients with treatment failures in the ciprofloxacin group included a quadriplegic patient with relapse of urinary tract infection with bacteremia (K. pneumoniae). Another patient with bacteremia (Pseudomonas aeruginosa), pneumonia (Proteus vulgaris), and urinary tract infection (P. vulgaris, Providencia sp.) died on the first treatment day. The third patient (S. aureus and Streptococcus pneumoniae pneumonia) had a new aspiration pneumonia develop on the third day; the pneumococcus also persisted. Undrained S. pneumoniae empyema caused the fourth ciprofloxacin treatment failure, and the fifth patient had a relapse of S. aureus pneumonia with bacteremia. One ceftazidime-treated patient died of pneumococcal pneumonia on the first day. Another had persistent Staphylococcus epidermidis and Listeria bacteremia despite 48 hours of treatment. Two other patients had pneumonia (S. aureus and P. aeruginosa, respectively) and completed full courses of ceftazidime therapy without improvement. Five patients had pneumococcal bacteremia; four patients were cured: one of two patients in the ciprofloxacin group and three of three patients in the ceftazidime group. Significant increases in the number of platelets (four patients with ciprofloxacin treatment, one patient with ceftazidime treatment) and declines in the number of platelets (one patient with ciprofloxacin treatment, one patient with ceftazidime treatment) were observed. Intravenously administered ciprofloxacin is comparable with ceftazidime and is a safe and effective antibiotic for the treatment of patients with serious infections, including bacteremia.

Eighteen patients 2 months to 11 years of age with culture proven bacterial infections were treated with parenteral ticarcillin/clavulanic acid in a noncomparative study. Seven patients had pneumonia, two had tracheobronchitis, three had soft tissue abscess, two had periorbital cellulitis, three had urinary tract infection and one had purulent bursitis. Four of the 18 were bacteremic. Organisms treated included Staphylococcus aureus (6), Pseudomonas aeruginosa (5), Haemophilus influenzae (2), Branhamella catarrhalis (2), Escherichia coli (1), Streptococcus pneumoniae (1), Klebsiella pneumoniae (1), Streptococcus pyogenes (1) and Serratia marcescens (1). Thirteen of 15 (87%) organisms tested were beta-lactamase positive. Therapy was given intravenously in six doses per day at 310 mg/kg. Duration of treatment ranged from 5 to 28 (mean 11) days, with an average time of 4 days to clinical improvement. Seventeen patients (94%) were clinically cured. One patient with recurrent aspiration pneumonia due to mixed infection with multiple gram-negative enteric bacilli failed therapy. Adverse effects were minimal and transient. Notably, mild to moderate thrombocytosis occurred in four (22%) patients that resolved uneventfully. We conclude that ticarcillin/clavulanic acid is safe and effective therapy for serious infections in hospitalized children.

To determine if there are any unique features of nursing home-acquired pneumonia we carried out a case-control study wherein each patient admitted with nursing home-acquired pneumonia was age- and sex-matched with a patient with community-acquired pneumonia. There were 36 men and 38 women in the nursing home group. The mean age of both groups was 74 years. The mortality rate for nursing home-acquired pneumonia it was 40.5%, whereas for community-acquired pneumonia it was 28% (P = NS). Patients with nursing home-acquired pneumonia had a significantly higher incidence of dementia and cerebrovascular accidents, and patients with community-acquired pneumonia were more likely to be smokers and to have chronic obstructive pulmonary disease. Aspiration pneumonia was more common among patients with nursing home-acquired pneumonia (P less than .001), and Hemophilus influenza pneumonia more common among the patients with community-acquired infection (P less than .01). Sputum for culture could be obtained in only 31 and 39% of the patients--contributory to the high rates of pneumonia of unknown etiology 63.5 and 56.1% for the nursing home group and the control subjects, respectively. Patients with nursing home-acquired pneumonia received cloxacillin and aminoglycosides more frequently than patients with community-acquired pneumonia (P less than .05), and patients with community-acquired pneumonia received erythromycin more frequently than patients with nursing home-acquired pneumonia (P less than .05). Complications were common during the hospital stay of these patients--the most frequent being congestive heart failure, urinary tract infection, renal failure, and respiratory failure.

This study prospectively examines 502 general medical patients for evidence of side-effect of hospitalization unrelated to diagnosis or therapy of acute illness. Symptoms of depressed psychophysiologic functioning (confusion, falling, not eating, and incontinence) unrelated to acute medical diagnoses were found in 8.8% of the patients under 70 and in 40.5% of the elderly population (P less than 0.0001). The rate of medical intervention secondary to these symptoms (psychotropic medications, restraints, nasogastric tubes, and foley catheters) was 37.9% among the young patients and 47.1% in the elderly group (P = 0.4). The sample was too small to permit adequate empirical determination of the complication rate from medical intervention (thrombophlebitis, pulmonary embolus, aspiration pneumonia, urinary tract infection, septic shock) but estimates from the literature indicate that each of the interventions studied entails a complication rate of 25-30%. Combining the observed rate of functional symptoms development and intervention, and the literature rates of complications, yields a risk of complications of 1.0% for the young and 5.7% for the elderly (P less than 0.0001). These data indicate that hospitalized elderly patients are at high risk of developing symptoms of depressed psychophysiology functioning and of sustaining medical intervention as a result of these symptoms, with attendant medical complications. We suggest that in incidence of depressed psychophysiologic function needs to be assessed in patients treated outside the hospital, along with efficacy of treatment outside the hospital, to determine whether there are patients for whom hospitalization is not optimal therapy.

Clinical studies on cefsulodin (CFS) in 6 patients with Pseudomonas aeruginosa infection were carried out and the results as follows. 1. Among 4 patients administered CFS intravenously, 3 patients (urinary tract infection 1, acute purulent otitis media 1, aspiration pneumonia 1) responded well. 2. Two patients with respiratory infection were treated CFS by nebulization. One responded well and another fair. 3. No side effects were observed.

The findings in 44 patients (42 of whom were chronic alcoholics) with central pontine myelinolysis show that the outcome does not depend on the severity of neurological deficits during the acute phase of the condition or on concomitant internal diseases, including the degree of hyponatremia. Of the 34 patients for whom follow-up data were available, 32 survived. Of these 11 completely recovered, 11 had some deficits but were independent, and 10 were dependent (4 through disorders of memory or cognition, 3 with tetraparesis, 2 with cerebellar ataxia, 1 with polyneuropathy). The electrophysiological findings did not contribute usefully to the prediction of outcome. Additional neuroradiological diagnostic testing with magnetic resonance imaging was also of no prognostic significance. The extent of the initial pontine lesion was not correlated with the severity of clinical findings during the acute phase of disease, nor was persistence of the pontine lesion as usually seen on magnetic resonance imaging correlated with clinical improvement. We conclude that patients with cerebral myelinolysis survive if the nonspecific secondary complications of transient illnesses such as aspiration pneumonia, ascending urinary tract infection with subsequent septicemia, deep venous thrombosis, and pulmonary embolism can be avoided.

Previous studies showed that elevated body temperature early after ischemic stroke is associated with severe neurological deficit and a poor outcome. The aim of this study was to analyse the prevalence and putative etiology of febrile body temperature (>/=38.0 degrees C) early after stroke and to investigate the association between body temperature, stroke severity and outcome. We investigated 119 consecutive patients who were admitted within 24 h after ischemic stroke. Patients were examined for infection before ischemia using a standardized questionnaire and received daily clinical examination after stroke. In case of fever, standardized radiological and microbiological examinations were performed. Fever within 48 h after stroke was observed in 30 (25.2%) patients. The probable cause of fever was infective or chemical aspiration pneumonia (n=12), other respiratory tract infection (n=7), urinary tract infection (n=4), viral infections (n=3) or insufficiently defined (n=5). (One patient had two potential causes of fever.) In thirteen of these patients, infection was most probably acquired before stroke. Fever newly developed more often during day 1 to 2 than day 3 to 7 after stroke (P=0.016). Fever was associated with a more severe deficit on admission independent from age, vascular diseases and risk factors (odds ratio 9.6; 95% confidence interval 3.1-29). Fever is a frequent complication early after stroke and in the majority of cases, it can be explained by infection or chemical aspiration pneumonia. In about half of the infected patients, infection was most probably acquired before stroke. Fever was associated with a more severe neurological deficit on admission.

The hospital course of a patient with a neurological disorder may be complicated by the development of fever, urinary tract infection (UTI), bacteremia, pneumonia, diarrhea, pressure sores, or intravenous line infections. An approach to each of these is provided in this review as well as recommendations for empirical therapy of catheter-related UTIs, intravenous line infections, and aspiration pneumonia.

A 99-year-old woman was admitted to Shizuoka Shimizu Municipal Hospital because of fever and anasarca. Imaging and laboratory tests showed pneumonia, urinary tract infection, and cardiac failure. The patient died 20 days after admission. An autopsy revealed marked diffuse dilations of the biliary tree ranging from the lower common bile duct to intrahepatic bile ducts. Intrahepatic calcium bilirubinate stones and biliary sludges were recognized within the dilated bile ducts. A unilocular cyst (2 cm in diameter) was present in the pancreatic head adjacent to the lower common bile duct, and it appeared to compress the common bile duct. Histologically, the walls of the dilated biliary tree showed proliferation of peribiliary glands, fibrosis, and infiltration of lymphocytes and neutrophils (cholangitis). The lumens of the dilated biliary ducts contained neutral and acidic mucins, fibrinous materials, bacteria, neutrophils, and Aspergillus fungi, in addition to the calculi and sludges. The background liver showed atrophy (400 g). The pancreatic unilocular cyst was composed of mucous columnar cells with a few infoldings, and the pancreas also showed foci of mucinous duct hyperplasia and ectasia; the pathological diagnosis of the cyst was cystic dilations of a pancreatic duct branch (mucinous ductal ectasia or mucinous cyst). Other lesions included aspiration pneumonia, emaciation, atrophy of systemic organs, gastric leiomyoma, serous cystadenoma of the right ovary, and arteriosclerotic nephrosclerosis. The present case suggests that a mucinous cyst of the pancreas may compress the biliary tree and lead to marked diffuse dilations of the biliary tree. Alternatively, the dilations of the bile ducts may be associated with aging or may be of congenital origin. The dilated bile ducts may, in turn, give rise to bacterial and fungal cholangitis and formation of biliary sludges and intrahepatic calcium bilirubinate stones.

The third most common stroke complication is infection. We studied the rates of aspiration pneumonia and urinary tract infection (UTI), their risk factors and their effect on outcome in the 1455 Glycine Antagonist (Gavestinel) in Neuroprotection (GAIN) International patients with ischaemic stroke. Forward stepwise logistic regression and Cox proportional hazards modelling identified baseline factors that predicted events and the independent effect of events up to day 7 on poor stroke outcome at 3 months in patients alive at day 7, after correcting for prognostic factors. Higher baseline National Institute of Health Stroke Scale (NIHSS) and age, male gender, history of diabetes and stroke subtype predicted pneumonia, which occurred in 13.6% of patients. Female gender and higher baseline NIHSS and age predicted UTI, which occurred in 17.2% of patients. Pneumonia was associated with poor outcome by mortality (hazard ratio, 2.2; 95% confidence interval, 1.5-3.3), Barthel index (<60) (odds ratio, 3.8; 2.2-6.7), NIHSS (4.9; 1.7-14) and Rankin scale (>/=2) (3.4; 1.4-8.3). UTI was associated with Barthel index (1.9; 1.2-2.9), NIHSS (2.2; 1.2-4.0) and Rankin scale (3.1; 1.6-4.9). Pneumonia and UTI are independently associated with stroke poor outcome. Patients with identified risk factors must be closely monitored for infection.
