Objective To study the CT and MR imaging feature of adult sphenoid spontaneous cerebrospinal fluid (CSF) rhinorrhea and accompanying intracranial hypertension. Methods Thirty consecutive patients including 11 males and 19 females with mean age of (50 ± 8) years (range, 31 to 64 years) were retrospectively reviewed. Imaging findings in 30 patients with adult sphenoid spontaneous CSF rhinorrhea (CT in 26 patients, MR in 29 patients, and both CT and MR in 25 patients) were analyzed. The MR imaging and CT features were evaluated by two experienced head and neck radiologists. The CT and MR imaging parameters of 30 fistulas were evaluated, including side, location, size, amount, bony change, and the adjacent structures change. Results Of the 30 patients of adult sphenoid spontaneous CSF rhinorrhea lesions, the site of the CSF fistula confirmed by endoscopy surgery was at the junction of the roof of the inferolateral recess and the floor of the middle cranial in 25 (83%, 25/30) patients, the roof of the inferolateral recess in 3 (10%,3/30) patients, and the lateral wall of the sphenoid sinus in 2 (7%,2/30). CT images revealed the osseous defects of the sphenoid sinus walls in 21 patients (80.7%, 21/26) patients, excessive pneumatization of the inferolateral recess of the sphenoid sinuses in 25 cases (96.1%, 25/26). MRI demonstrated the linear hyperintensity communicating subarachnoid space and sphenoid cavity, accompanying meningoencephalocele in 26 (89.6%, 26/29) patients, sphenoid sinus filled with CSF in 24 (82.7%,24/29) patients and air-fluid level in the sphenoid sinus in 8 cases (27.6%, 8/29), excessive expansion of adjoining lateral fissure cistern in 22 cases (75.9%,22/29), adjoining sulcus in one case (3.4%, 1/29), adjoining lateral ventricle in one case (3.4%,1/29). The imaging feature of accompanying intracranial hypertension included empty sella in 29 cases (100%, 29/29), augmentation of the complex of the optic sheath in 27 cases (93.1%, 27/29), the arachnoid pits in the middle cranial fossa in 30 cases (100%). Conclusions The spontaneous CSF fistula coexists with intracranial hypertension. The combined application of CT and MRI can accurately identify the fistula with accompanying symptom and the intracranial hypertension.

Objective To investigate the association of AcrAB-tolC efflux pump and marA-soxS-rob regulon with ciprofloxacin-resistance in Shigella flexneri isolates.Methods Forty five strains of Shigella flexneri were isolated in stool samples collected from outpatient diarrhea clinics in Tianjin from 2009 to 2013.The antimicrobial susceptibility of bacteria was analyzed by Kirby-Bauer disk diffusion method.Ten ciprofloxacin-resistant Shigella flexneri isolates and 10 ciprofloxacin-sensitive isolates were randomly selected.The gyrA and parC genes,plasmid mediated quinolone resistant (PMQR) determinants,efflux pump genes (acrA,acrB) and regulation genes (marA,soxS,rob) were screened and sequenced.Minimum inhibition concentrations (MICs) of the strains were determined before and after efflux pump inhibitor carbonyl cyanide m-chlorophenylhydrazone (CCCP) was added.The expression of acrA,acrB,marA,soxS and rob genes in ciprofloxacin-resistant and ciprofloxacin-sensitive strains was detected by realtime fluorescence quantitative RCR (RT-PCR),and the differences of expression were evaluated using t test.Results Both gyrA and parC mutations were detected in all ciprofloxacin-resistant strains; qnrS1 was positive in ciprofloxacin-resistant strain CR2 and aac(6')-Ib-cr was positive in ciprofloxacin-resistant strain CR5.Efflux pump genes and regulation genes were not detected in ciprofloxacin-sensitive strains,while soxRS mutation was detected in all ciprofloxacin-resistant strains except CR10.MICs of quinolones in ciprofloxacin-resistant strains decreased to one-fourth or one-eighth when CCCP added,while not changed or only decreased to one-half in ciprofloxacin-sensitive strains.Expressions of acrA,acrB,marA and soxS were significantly higher in ciprofloxacin-resistant strains than those in ciprofloxacin-sensitive strains (P ＜ 0.05 or P ＜ 0.01).Conclusion Efflux pump may involve in the high-level ciprofloxacin resistance in Shigella flexneri through activating transcription of efflux pump genes by marA-soxS-rob regulon,in which soxRS mutation may play an important role.
