We present a case of H. parainfluenzae complicating pregnancy in the second trimester. Predisposing factors for infection with Haemophilus species and Australasian data on invasive neonatal Haemophilus infections are presented. [ncbi.nlm.nih.gov]

• Mitral Valve Prolapse

  A case of H. parainfluenzae endocarditis is presented in a patient with mitral valve prolapse, which illustrates the difficulty in diagnosing endocarditis when initial blood cultures are negative. [ncbi.nlm.nih.gov]

• Neck Pain

  A 74-year-old man presented with neck pain and subsequently developed incomplete quadriparesis. A cervical epidural abscess and vertebral osteomyelitis were detected by radiologic studies. [ncbi.nlm.nih.gov]

  His complaint of neck pain associated with intermittent fever and chills was initially concerning for meningitis; therefore, after obtaining a cranial computed tomography (CT) scan, a lumbar puncture was performed. [journals.sagepub.com]

• Spontaneous Rupture of Membranes

  There was spontaneous rupture of membranes for   12 hours before delivery. The duration of labor in the water tub was not documented. The mother reported a rapid vaginal delivery after three pushes. [ncbi.nlm.nih.gov]

• Prolapse

  A case of H. parainfluenzae endocarditis is presented in a patient with mitral valve prolapse, which illustrates the difficulty in diagnosing endocarditis when initial blood cultures are negative. [ncbi.nlm.nih.gov]

• Confusion

  We report a case of H. parainfluenzae endocarditis in which confusion related to microbial identification was resolved by the analysis of 16S ribosomal RNA sequences. [ncbi.nlm.nih.gov]

  The non- Haemophilus spp. were chosen as extended negative controls for the FISH evaluation because they are representatives of commensal or pathological flora of the naso-oro-pharyngeal mucous membranes that should not be confused with Haemophilus spp [journals.plos.org]

• Limb Weakness

  We present the case of a 49-year-old man with a bicuspid aortic valve who presented to the emergency department with limb weakness and a fever. [ncbi.nlm.nih.gov]

• Urethral Discharge

  Haemophilus parainfluenzae was isolated from the urethral discharge of a man with urethritis. The patient responded favorably to treatment with amoxicillin. [ncbi.nlm.nih.gov]

• Macroscopic Hematuria

  IgA-N patients with macroscopic hematuria or arterio(lo)sclerosis had a significantly higher IgA antibody titer than other IgA-N patients. There was no relationship between renal lesions and IgG or IgM antibody titers in any group. [ncbi.nlm.nih.gov]

Initially, the systolic murmur heard on exam was not the focus of the diagnostic workup given that his symptoms were highly suggestive of meningitis. Mitral valve perforation and vegetation were eventually discovered via TEE. [journals.sagepub.com]

Antibiotic treatment of native valve infective endocarditis (IE) traditionally consists of 4-6 weeks of intravenous (IV) antibiotic therapy. [ncbi.nlm.nih.gov]

In a series of 57 cases of A actinomycetemcomitans endocarditis, poor dentition (46%) and abnormal cardiac valves (60%) were found to be predisposing factors. [12] Prognosis The prognosis is quite variable, depending on many factors, such as delay in [emedicine.medscape.com]

Although the facts suggest that this case of urethritis may have been caused by H. parainfluenzae, a possible etiologic role of other microorganisms is not ruled out. [ncbi.nlm.nih.gov]

Overall, these organisms are the leading cause of exacerbations of chronic bronchitis, and the second most common etiology of acute otitis media and sinusitis. [encyclopedia2.thefreedictionary.com]

The human microbiota has multidirectional effects on the host’s health and changes in its composition may have important consequences for human pathophysiology and disease development [5, 7, 8, 34]. [bmcinfectdis.biomedcentral.com]

We report a rare case of tricuspid valve and pacemaker endocarditis caused by this organism and explore factors related to etiopathogenesis, prevention, and treatment. [ncbi.nlm.nih.gov]

To prevent a further infection in that critical situation, we treated the patient with fleroxacin, although the susceptibility profile of the isolated strain indicated no resistance to any of the tested agents, including amoxicillin-clavulanic acid, aminopenicillin [jcm.asm.org]
