Article Synopsis
  • * A review of 52 cases in Japan identified cough, fever, and difficulty breathing as common symptoms, typically affecting young adults with no significant underlying health issues.
  • * Most patients improved after receiving appropriate treatments, including anti-mycoplasmal drugs and steroids, while the misuse of standard antibiotics prior to hypoxia may increase risks.

We report the case of a 62-year-old man who developed eosinophilic pneumonia due to visceral larva migrans (VLM) that was possibly caused by Ascaris suum. The patient, a resident of the middle Kyushu area who was found of eating raw porcine liver, complained of dry cough without dyspnea. The chest radiography showed a migration of infiltrative shadow.

Changes in nasopharyngeal bacterial flora in adults with acute upper respiratory tract infection on administration of antimicrobial agents were investigated, and how these changes contrasted with those in children. Many patients with acute sinusitis due to allergies, and patients with malignancy and diabetes mellitus were included in the investigation. The detection rates of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, the major bacteria of acute otitis media (AOM), were 22%, 10%, and 7% respectively, which were significantly lower than those for children.

This report focuses on changes in the nasopharyngeal bacterial flora before and after administration of antimicrobial agents in 172 cases of acute upper respiratory infection in patients aged 6 years or younger. The antimicrobial agents administered were amoxicillin (AMPC) (34%), clavulanic acid/amoxicillin compound (11%), cefditren pivoxil (CDTR-PI) (43%), and others (12%). Changes in nasopharyngeal bacterial flora were investigated with reexaminations conducted after 2-5 days (day 2-5 subgroup), 6-10 days (day 6-10 subgroup), and 11 days and thereafter.

Article Synopsis
  • The study examined the nasopharyngeal bacterial flora of 172 children under 6 with acute upper respiratory tract infections (AURTI), focusing on penicillin-resistant Streptococcus pneumoniae (PRSP) and ampicillin-resistant Haemophilus influenzae (BLNAR).
  • Findings indicated that 90% of the patients had acute otitis media (AOM), predominantly affecting those aged 2 and under, with a notable prevalence of gPRSP in children treated with cefditren pivoxil (CDTR-PI).
  • A significant correlation was found between the degree of inflammation in the nasopharynx and the presence of S. pneumoniae and H. influenzae, highlighting the importance of

Objective: The aim of this study is to determine whether a questionnaire-based method using the Veterans Specific Activity Questionnaire (VSAQ) is a practical tool for the development of a safe exercise program to prevent a reduction in physical performance.

Methods: One hundred and twenty-one senior residents of Yakage, Okayama, agreed to voluntarily participate in this study. They were asked to complete a questionnaire for information on age, sex, subjective health status, exercise habits and VSAQ.

We experienced a case of a 76-year-old man who developed a splenic abscess while undergoing treatment for interstitial pneumonia. Splenic abscess-like abnormal intensities were accidentally found by the chest computed-tomography (CT) examinations 3 weeks after the initiation of corticosteroids and immunosuppressive treatment for interstitial pneumonia. An ultrasonography-guided percutaneous aspiration test resulted in the isolation of methicillin-resistant Staphylococcus aureus (MRSA).

With the appearance of penicillin-resistant Streptococcus pneumoniae, there has been increasing debate concerning antimicrobial treatments for acute upper respiratory tract infection (AURTI) and acute otitis media in children. This study compares the nasopharyngeal bacterial flora in patients with AURTI (AURTI group; 710 subjects) and healthy subjects (HS group; 380 subjects). The comparisons were made between subjects aged 6 years or younger (0-6 subgroup: 330 subjects), between 7 and 74 years (7-74 subgroup: 668 subjects), and 75 years and older (92 subjects), because the subjects were subgrouped as described above dependent on the maturity of the protective immunity.

We report here two cases of Legionella pneumophila pneumonia that were markedly improved by parenteral ciprofloxacin administration. A 69-year-old man who had previously visited a hot spring was admitted to our hospital with severe pneumonia and a 48-year-old man with dilated cardiomyopathy as an underlying disease was also hospitalized because of heart failure and pneumonia. In both cases a urinary antigen test for L.

We evaluated the efficacy of antimicrobial agents used for patients with community-acquired pneumonia (CAP) based on the guidelines of Japanese Respiratory Society. A total of ninety-nine hospitalized patients who were suspected to have bacterial pneumonia at the time of admission between January, 1998 and December, 2000 were assessed. Our conclusions were as follows.

Infection is a major complication associated with increased morbidity and mortality in patients on hemodialysis. We analyzed the incidence and type of infection occurring in 4841 patients on hemodialysis between 1986 and 1993 in our hospital and 11 other hemodialysis centers. Infection was noted in 193 patients (4.

The efficacy, safety, and clinical utility of DU-6859a, a novel "new quinolone" antibacterial agent, were evaluated in patients with mild-to-moderate pneumonia or chronic respiratory tract infection (RTI) in a multicenter study. DU-6859a was administered orally after meals at a dose of 50 to 100mg, mainly twice daily, for 6 to 14 days. The clinical efficacy rate was 100% (26/26) for pneumonia and 89% (66/74) for chronic RTI, for an overall clinical efficacy rate of 92% (92/100).
