Case Reports[Purpura fulminans complicating pneumococcal sepsis: a case report].
An unusual case of a 67-year-old man is reported with fulminant pneumococcal sepsis. He had been healthy before, and the identified predisposing factors were only that he was a chronic alcohol drinker and was a HCV carrier. He presented signs of acute renal failure, liver dysfunction, adult respiratory distress syndrome and disseminated intravascular coagulation. ⋯ But in Japan the previously reported adult case was the only one complicating Xanthomonas maltophilia sepsis, and none accompanying pneumococcal sepsis. Congenital protein C deficiency is recognized to be able to cause purpura fulminans especially in patients with risk factors. In our case, protein C antigen was decreased in the acute stage but gradually increased later toward normal, so this decrease was thought to be concomitant with the initial disseminated intravascular coagulation rather than compatible with protein C deficiency.

Case Reports[A case of Aspergillus niger pneumonia cured with an early diagnosis].
We have experienced a case with A. niger aspergilloma who developed Aspergillus pneumonia after bacterial pulmonary infection. Examinations of sputum cytology and detection of serum Aspergillus antigen were useful for an early diagnosis of his condition. Early and intensive antifungal chemotherapy mainly with intravenous amphotericin B brought about his complete remission.

[Purple urine bag syndrome (PUBS) associated with strong alkaline urine].
Mechanisms for purple discoloration of the plastic urine bag in purple urine bag syndrome (PUBS) were investigated. Activities of bacterial indoxyl sulfatase catalyzing the conversion of indoxyl sulfate to indigo (or indirubin) were detected in strong alkaline liquid media but not in normal ones. These enzyme activities were particularly high in simple and combined cultures of Proteus mirabilis and/or Klebsiella pneumoniae. These results suggest that occurrence of PUBS is associated with strong alkaline urine as well as urinary tract infections induced by some species of bacteria with indoxyl sulfatase.

Comparative Study[An infection model which was induced in a carboxymethyl cellulose (CMC) pouch on the back of the rat].
The air-pouch model of inflammation in rats is excellent in that it allows quantitative evaluation of inflammation, and it is used for analysis of inflammatory mediators and as an evaluation system for anti-inflammatory drugs. We investigated the possibility of using this system as an experimental infection system. As a result, inflammation was found to be caused by injection of a constant amount of Staphylococcus aureus solution (10(4)-10(8)). ⋯ The infiltrating cells consisted mainly of neutrophils. In this experimental model of infectious disease, the severity of inflammation could be quantitatively evaluated as a function of time in terms of bacterial proliferation and the body's response to bacterial proliferation based on the amount of fluid in the air pouch and the number of infiltrating cells, suggesting that the model is useful. In this experimental system, there were no differences between the number of live bacteria, the number of infiltrating cells or the amount of infiltration when S. aureus Smith strain and clinically-isolated methicillin-resistant S. aureus (MRSA) were used, suggesting that there is no difference between the inflammation-induced activity of MRSA and MSSA.

Comparative Study[Clinical efficacy of flomoxef in neonatal bacterial infection].
One hundred and seventy one neonates were treated with flomoxef (FMOX) and the clinical efficacy and safety were evaluated. The ages of the patients ranged from 0 to 28 days, and their body weights from 450 to 4300 g. Dose levels were 12.4 to 24.9 mg/kg every 8 or 12 hours for 1 to 10 days. ⋯ The drug was well tolerated, but 6 neonates out of 33 over 5 days old had diarrhea. From these results, empiric treatment with FMOX against neonatal bacterial infection was as clinically useful as that of combination with ampicillin and gentamicin or cefotaxime and ampicillin in our neonatal intensive care unit. But, as this study did not include neonate with meningitis, efficacy to meningitis was not evaluated.
