Seven children (aged 8--17 years) presented with a high fever, headache, confusion, conjunctival hyperaemia, a scarlatiniform rash, subcutaneous oedema, vomiting, watery diarrhoea, oliguria, and a propensity to acute renal failure, hepatic abnormalities, disseminated intravascular coagulation, and severe prolonged shock. One patient died, one had gangrene of the toes, and all have had fine desquamation of affected skin and peeling of palms and soles during convalescence. Five patients were studied prospectively. Staphylococcus aureus related to phage-group I was isolated from mucosal (nasopharyngeal, vaginal, tracheal), or sequestered (empyema, abscess) sites, but not from blood. This organism produces an exotoxin which causes a positive Nikolsky sign in the newborn mouse and which is biochemically, pathologically, and immunologically distinct from phage-group-II stapphylococcal exfoliatin.

Localized suppuration involving the spinal cord is uncommon. A case of spinal subdural empyema is reported. The patient is 54-year-old male who had been suffering a diabetes mellitus but did not receive any treatment. His initial symptom was lumbago. Then he noticed a palpitation and general malaise which made him visit a hospital. Because he did not show any improvement by a fluid therapy, he was transferred to our institute for the further evaluation. On admission, physical examination showed no abnormality. Blood pressure was 170/90 mmHg, heart rate 128/min. and body temperature 37.1 degrees C suggesting a septic shock state. Neurological examination revealed slight consciousness disturbance, mild tetraparesis and bilateral hypesthesia lower than the level of L3. Laboratory examination showed the elevated leukocyte count and fasting blood sugar and urine ketone body levels of 20,500/mm3, 257 mg/dl and 226 mg/dl respectively. Blood culture proved a septicemia of Streptococcus agalactiae afterwards. On the second day of admission, lumbar puncture revealed a purulent cerebrospinal fluid, though X-ray CT of lumbar spine did not confirm a diagnosis. Spinal magnetic resonance imaging (MRI) revealed a widespread abnormal intensity of the spinal canal from the level of Th11 to L4. On the T1-weighted image (TR 300 msec., TE 40 msec.), cerebrospinal fluid space was abnormally isointense. On the T2-weighted image (TR 2,000 msec., TE 80 msec.), subdural and cerebrospinal space was filled with an abnormal high-intense lesion especially on the ventral side. He developed semicoma due to hydrocephalus following a intraventricular empyema. He was also complicated disseminated intravascular coagulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Because of the critical role of neutrophils in host defenses, it was hypothesized that stimulation of neutrophil production and function with Filgrastim would improve the outcome of hospitalized patients with community-acquired pneumonia. To test this hypothesis, a randomized, placebo-controlled, multicenter trial of Filgrastim (300 micrograms/day up to 10 days) as an adjunct to antibiotics was conducted for these patients. Outcome measures included time to resolution of morbidity (TRM, a composite measure of temperature, respiratory rate, blood oxygenation, and chest radiograph), 28-day mortality, length of stay, and adverse events. Filgrastim increased blood neutrophils 3-fold, but TRM, mortality, and length of hospitalization were not affected. Treatment, however, accelerated radiologic improvement and appeared to reduce serious complications (e.g., empyema, adult respiratory distress syndrome, and disseminated intravascular coagulation). Filgrastim administration was safe and well tolerated in these patients. Additional trials are needed to establish the value of this approach to treatment of infectious diseases.

A total of 103 patients with acute progressive pulmonary tuberculosis whose age ranged from 18 to 60 years were examined. Caseous pneumonic, infiltrative-caseous, disseminated, and rapidly progressive fibrocavernous tuberculosis was found in 45.6, 17.5, 16.5, and 20.4% of cases, respectively. The clinical picture was characterized by its acute onset with significant intoxication syndrome. Moreover, all the patients had respiratory and immunological failure, varying disseminated intravascular coagulation syndrome, non-specific bronchopulmonary infection; some presented with pulmonary hemorrhage, spontaneous pneumothorax and pleural empyema. The sputum smear test was positive in all the patients. If there was no evidence for drug resistance, patients had a 4-month regimen using isoniazid, rifampicin, pyrazinamide, ethembutol, and kanamycin. In the subsequent 10-12 months, isoniazid, rifampicin, and ethambutol were given. The patients with multidrug resistant tuberculosis were administered protionamide, ofloxacin, amikacin, supplemented by pyrazinamide and ethambutol. The combined chemotherapy could stop bacterial isolation in more than 80% of patients, make the process stable, and prepare them for planned surgical treatment. When complications occurred and the disease was in steady progress, salvage operations were made, which was the only possible way of preventing the progression of disease at times and of saving life in the patient.

We assessed the frequency and clinical significance of polymicrobial infections in 31 patients with sporadic community-acquired Legionella pneumonia. Twenty-six patients were men, 5 were women and mean age was 61 years. Eighteen patients were smokers, 6 patients were chronic alcoholics and 23 had underlying diseases. Regarding severity, the illnesses were mild (two patients), moderate (seven patients) and severe (twenty-two patients). In 9 (29%) of the patients, one other etiologic agent for community-acquired pneumonia was identified in addition to the Legionella species. The distribution of one other causal agent was as follows: Mycoplasma pneumoniae, 2 patients; Chlamydia pneumoniae, 2; Chlamydia psittaci, 1; Influenza virus, 1; Streptococcus pneumoniae, 1; Klebsiella pneumoniae, 1; Pseudomonas aeruginosa, 1 patient. Because an antimicrobial agent with activity against Legionella species can also provide coverage for Mycoplasma pneumoniae. Chlamydia pneumoniae, and Chlamydia psittaci, the patients with these coinfections improved without any complications. The patient with influenzavirus coinfection became seriously ill, and the condition was complicated by disseminated intravascular coagulation, renal failure and aspergillus bronchitis. The case of Pseudomonas aeruginosa coinfection was accompanied with a lung abscess and empyema. Our experience illustrates the importance of considering polymicrobial infections in patients with sporadic community-acquired Legionella pneumonia.

A multicenter study of 638 cases of community-acquired pneumonia due to Streptococcus pneumoniae (SP-CAP) was performed to assess current levels of resistance. Of the pneumococcal strains, 35.7% had an minimum inhibitory concentration (MIC) of penicillin of > or =0.12 microg/mL (3 isolates had an MIC of 4 microg/mL), 23.8% had an MIC of erythromycin of 128 microg/mL, and 22.2% were multidrug resistant. Logistic regression determined that chronic pulmonary disease (odds ratio [OR], 1.44], human immunodeficiency virus infection (OR, 1.98), clinically suspected aspiration (OR, 2.12), and previous hospital admission (OR, 1.69) were related to decreased susceptibility to penicillin, and previous admission (OR, 1.89) and an MIC of penicillin of MIC > or =0.12 microg/mL (OR, 15.85) were related to erythromycin resistance (MIC, > or =1 microg/mL). The overall mortality rate was 14.4%. Disseminated intravascular coagulation, empyema, and bacteremia were significantly more frequent among patients with penicillin-susceptible SP-CAP. Among isolates with MICs of penicillin of > or =0.12 microg/mL, serotype 19 was predominant and was associated with a higher mortality rate. In summary, the rate of resistance to beta -lactams and macrolides among S. pneumoniae that cause CAP remains high, but such resistance does not result in increased morbidity.

We report the case of an 18-year-old woman who was admitted to the medical intensive care unit in Innsbruck with severe septic shock and respiratory insufficiency following a prolonged infection of the upper airways (pharyngitis, sinusitis). Abscessing pneumonia and bilateral pleural empyema were diagnosed as focus. Cultures of pleural fluids were positive for Fusobacterium necrophorum. In addition to multiple organ dysfunction syndrome (acute lung injury, acute renal failure, disseminated intravascular coagulation), she developed tenderness in the right neck followed by septic arthritis of the right sternoclavicular joint a few days later. Further history revealed a previous period of infectious mononucleosis (EBV infection). The previously healthy patient eventually made a complete recovery after prolonged treatment in the ICU including antibiotic therapy and multiple surgical interventions and drainage. Lemierre's syndrome is characterized by severe infection, with pharyngitis, sepsis and thrombosis of the internal jugular vein, and is most frequently associated with upper airway infection with Fusobacterium necrophorum, often preceded by infection with Epstein-Barr virus which enables bacteria growing in the oral cavity to invade.

An 80-year-old man who had undergone total gastrectomy and splenectomy for gastric cancer 13 years ago presented with headache, drowsiness, and high fever 1 month after a traffic accident. Brain CT scans revealed bilateral subdural fluid collections. Diffusion-weighted imaging (DWI) showed mixed high and low signal intensities in the left subdural fluid, and contrast-enhanced MR imaging revealed capsule enhancement of the left subdural fluid collection. The patient was diagnosed with left subdural empyema, and 2 burr-holes were drilled for drainage and irrigation. Operative findings revealed a neomembrane underneath the dura mater. Old hematoma and yellowish-white purulent fluid were present within the neomembrane. This confirmed the diagnosis of infected subdural hematoma (ISH). Abscess culture results were positive for Escherichia coli. The patient's symptoms resolved postoperatively with subsequent antibiotic therapy. However, 4 months after the operation, he suddenly died of severe sepsis and disseminated intravascular coagulation following cholecystitis, which was possibly associated with splenectomy. The clinical presentation, diagnosis, and treatment of an unusual case of ISH have been discussed. We emphasize that DWI and enhanced MR imaging may be useful for diagnosing ISH, and serial DWI evaluations may help in monitoring the therapeutic response in ISH.

Group A Streptococcus (GAS, Streptococcus pyogenes) causes invasive infections including streptococcal toxic shock syndrome (STSS) and local infections. To our knowledge, this is the first report of a case of an invasive GAS infection with pneumonia and pleural empyema (PE) followed by STSS (disseminated intravascular coagulation [DIC] and acute renal insufficiency) in a healthy male adult. He received combined supportive therapies of PE drainage, anti-DIC agent, hemodialysis, and antimicrobials and eventually made a clinical recovery. GAS isolated from PE was found to have emm1/speA genes, suggestive of a pathogenic strain. Clinicians should be aware of the possibility of this disease entity (pneumonia, PE, and STSS) in healthy male adults as well as children and adult women.

Complicated community-acquired pneumonia in a previously well child is a severe illness characterised by combinations of local complications (eg, parapneumonic effusion, empyema, necrotising pneumonia, and lung abscess) and systemic complications (eg, bacteraemia, metastatic infection, multiorgan failure, acute respiratory distress syndrome, disseminated intravascular coagulation, and, rarely, death). Complicated community-acquired pneumonia should be suspected in any child with pneumonia not responding to appropriate antibiotic treatment within 48-72 h. Common causative organisms are Streptococcus pneumoniae and Staphylococcus aureus. Patients have initial imaging with chest radiography and ultrasound, which can also be used to assess the lung parenchyma, to identify pleural fluid; CT scanning is not usually indicated. Complicated pneumonia is treated with a prolonged course of intravenous antibiotics, and then oral antibiotics. The initial choice of antibiotic is guided by local microbiological knowledge and by subsequent positive cultures and molecular testing, including on pleural fluid if a drainage procedure is done. Information from pleural space imaging and drainage should guide the decision on whether to administer intrapleural fibrinolytics. Most patients are treated by drainage and more extensive surgery is rarely needed; in any event, in low-income and middle-income countries, resources for extensive surgeries are scarce. The clinical course of complicated community-acquired pneumonia can be prolonged, especially when patients have necrotising pneumonia, but complete recovery is the usual outcome.
