Nearly-complete labial adhesions diagnosed with repetitive cystitis in postmenopausal women:A case report

BACKGROUND Nearly-complete labial adhesions diagnosed with repetitive cystitis in postmenopausal women:A case report CASE SUMMARY The case of an 83-year-old woman who presented with dysuria,urination disorders,recurrent cystitis,and bacteriuria and was admitted to a private hospital after 1 mo of antibiotic treatment without improvement of her symptoms.Upon examination,labial adhesions were observed with nearly-complete labial fusion with a pinpoint opening.Bacteriuria was detected in urine analysis,and the urine culture test was positive for Escherichia coli.Therefore,a parenteral antibiotic(Fosfomycin)and topical estrogen cream were administered.However,since the adhesion did not separate after 2 wk of treatment,surgical correction was performed.First,adhesiolysis was conducted with a blunt instrument.Then,hysteroscopy and cystoscopy were performed.Hysteroscopic findings showed no abnormalities of the endometrium and endocervix,and the cystoscopic results were also normal.Finally,labiaplasty was completed to prevent adhesion recurrence.One month after the surgery,the discomfort while urinating was eliminated and the adhesion did not recur.CONCLUSION Labial adhesions in postmenopausal women cannot be successfully treated with estrogen creams,and surgical treatment should be considered.

All-hydrocarbon,all-conjugated cycloparaphenylene-polycyclic aromatic hydrocarbon host–guest complexes stabilized by CH–πinteractions

Polycyclic aromatic hydrocarbons(PAHs)are promising nanocarbon materials with diverse optoelectronic properties,yet they also pose concerning environmental and health risks.Despite the ubiquity of PAHs in the environment(crude oil,emissions,and biomass),most supermolecules rely on heteroatoms for stability.We discovered and characterized a family of all-hydrocarbon,all-π-conjugated[n]cycloparaphenylene-PAH host–guest complexes.We built a theoretical framework to rapidly select these complexes and predict their stabilities,driven exclusively by CH–πinteractions.More than a dozen complexes were confirmed experimentally and assembled directly from commercially available compounds.This motif offers a versatile way to combine the advantageous properties of organic semiconductors with the rich dynamic,stereochemical,stimulus-responsive,and stressdissipative behavior of host–guest complexes,while creating new opportunities for bespoke PAH separation or remediation materials.
