Prognostic Factors for Japanese Adults With Acute Community-Acquired Bacterial Meningitis: A Retrospective Study.

Background This study aimed to determine if the cerebrospinal fluid (CSF) cell count is useful for predicting the infection severity or prognosis in Japanese adults with community-acquired bacterial meningitis. Methodology This study retrospectively evaluated the prognosis of patients diagnosed with community-acquired bacterial meningitis at our hospital from January 2004 to December 2021 using the modified Rankin scale (mRs) (Showa General Hospital; N = 39). Patients were classified into the following two groups: (i) favorable (mRs: 0-3) and (ii) unfavorable (mRs: 4-6).

Phenotypic and Genotypic Traits of Pasteurella multocida subsp. septica Isolates From the Wounds of Two Patients Due to Dog or Cat Biting, 2023.

We describe the phenotypic and genotypic traits of subsp. isolates from the dog/cat bite wounds of two patients in 2023.

Exploring the Factors Affecting the Transferability of Vancomycin to Cerebrospinal Fluid in Postoperative Neurosurgical Patients with Bacterial Meningitis.

Vancomycin (VCM) is a standard treatment for bacterial meningitis. However, little is known about the transferability of VCM to cerebrospinal fluid (CSF), thus evidence of the transferability of VCM to CSF during bacterial meningitis is needed. In this study, we evaluated the concentration of VCM in the plasma and CSF of postoperative neurosurgical patients with bacterial meningitis and evaluated the factors that affect the transferability of VCM to CSF.

bacteremia one month after contact with raw venison: A case report.

is a gram-positive bacillus that causes food poisoning. Listeriosis causes gastrointestinal infections and occasionally leads to fatal bacteremia in older adults. The symptoms of infections are non-specific and difficult to diagnose.

Influences of protein levels on the cerebrospinal fluid distribution of ceftazidime & ceftriaxone in the cerebrospinal fluid of patients with inflamed meningitis.

Introduction: Ceftazidime and ceftriaxone are used to treat various gram-negative pathogens, such as Streptococcus pneumoniae and Pseudomonas aeruginosa, and have shown excellent therapeutic efficacy against bacterial meningitis. However, there is insufficient information on the pharmacokinetic characteristics of their cerebrospinal distribution. Here, we investigated the association of clinical laboratory data in cerebrospinal fluid with ceftazidime and ceftriaxone concentration in the cerebrospinal fluid of patients with inflamed meningitis.

Pulmonary embolism after dexamethasone treatment for COVID-19: a case report.

Background: Although the RECOVERY trial showed that dexamethasone was efficacious for the treatment of coronavirus disease 2019 (COVID-19), its impact on the risk of pulmonary embolism (PE) and other serious procoagulant events was not assessed.

Case Presentation: Here we report the case of a previously healthy 83-year-old woman with COVID-19, without any genetic predisposition to thrombosis. She developed moderate respiratory distress 12 days after symptom onset and a 10-day course of dexamethasone therapy was initiated.

Community-acquired Pseudomonas aeruginosa Osteomyelitis Caused by an Injury from a Dishwasher.

A 70-year-old healthy woman came to our hospital with right index finger pain and swelling after an injury incurred due to a commercial dishwasher. X-ray of the hand showed osteolysis around the distal interphalangeal joint. A further examination revealed Pseudomonas aeruginosa in the unexposed pus, so the patient was treated with a total of 10 weeks of cefepime, followed by levofloxacin and debridement twice.

Bacteremia Caused by Both Serogroup 2 and .

Different intra-cerebrospinal distribution of linezolid in patients with inflammatory meningitis.

Linezolid has excellent antibiotic activity against gram-positive organisms and is expected to be an alternative to vancomycin for the treatment of bacterial meningitis. Accumulated evidence has shown the superior pharmacokinetic characteristics of linezolid to vancomycin, such as cerebrospinal fluid penetration. However, in the treatment of meningitis, pharmacokinetic information regarding the intra-cerebrospinal distribution of linezolid and the effects of drainage on the linezolid concentration in the cerebrospinal fluid are unclear.

Case studies of SARS-CoV-2 treated with favipiravir among patients in critical or severe condition.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak is rising globally. However, clinically effective antiviral treatments are not established. Favipiravir may prevent pneumonia and acute respiratory distress syndrome aggravation.

The first report of human meningitis and pyogenic ventriculitis caused by Streptococcus suis: A case report.

Streptococcus suis, a gram-positive facultative anaerobe commonly found in pigs, is an emerging zoonotic pathogen. Herein, we describe a case of a 45-year-old male Japanese meat wholesaler with S. suis meningitis and pyogenic ventriculitis.

A case of breakthrough fungemia during micafungin therapy for a bloodstream infection.

We describe a case of breakthrough Candida parapsilosis fungemia in an 80-year-old woman with pyoderma gangrenosum and rheumatoid arthritis. C. parapsilosis was detected in blood culture while the patient was treated with micafungin for a Candida glabrata bloodstream infection.

[Confusion Over the Term "Contamination Rate" as It Pertains to Blood Cultures].

The blood culture contamination rate is often used to validate specimen-collection procedures. CUMITECH has set its optimal target to be 2% to 3%. However, the term "contamination rate" has been defined in many ways, limiting its generalizability.

[A case of meningococcal meningitis that was difficult to treat owing to concurrent ventriculitis].

A 64-year-old male came to our hospital emergency department with fever and consciousness disturbance. Culture tests of blood and spinal fluid samples revealed meningococci (Neisseria meningitidis), and we made a diagnosis of meningococcal meningitis. Brain magnetic resonance imaging (MRI) findings revealed ventriculitis.

[A Case of Bacteremia Which Followed a Urinary Tract Infection by Oligella urethralis].

An 82-year-old bedridden man with sequelae from a cerebral infarction was admitted to a welfare institution for the elderly. He developed a high fever and hematuria and was prescribed levofloxacin for the treatment of a suspected urinary tract infection. Although his condition improved, the symptoms subsequently recurred; therefore, levofloxacin was again administered.

[Isolation of the yeast-like fungus Stephanoascus ciferrii by culturing the aural discharge of a patient with intractable otitis media. Case report].

As longer lives have become possible due to advances in medical technology and diagnostic technology in recent years, weakly toxic fungus have been emerging as causative agents of opportunistic infections, primarily in high-risk groups. We report a case in which the yeast-like fungus Stephanoascus ciferii, which has morphological characteristics that differ from those of the more common Candida species, was isolated by culturing the aural discharge of a patient with intractable otitis media. Drug susceptibility testing showed that it was resistant to fluconazole, flucytosine, and itraconazole, suggesting that it is a species that has a strong tendency to become resistant.
