Among the ever-increasing literature of the coronavirus disease 2019 (COVID-19), there have been reports on several complications in association with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), such as secondary bacterial and fungal infections. We report a 61-year-old woman with a past history of diabetes mellitus who presented to our hospital suffering from COVID-19 infection. During the course of her hospitalization, the patient developed chemosis and proptosis in both eyes, ultimately leading to a diagnosis of invasive rhino-orbital-cerebral mucormycosis and cerebrovascular thrombosis. This study strengthens the possible association between the occurrence of COVID-19 and invasive mucormycosis infection, providing new impetus for further investigations to substantiate this correlation.
Objective: Many methods have been described for the repair of the tympanic membrane, but there is no general consensus as to the standard method. The aim of this study was to evaluate the effect of the inferior base posterior canal skin flap on the graft success rate in large tympanic membrane perforations.Methods: After the post-auricular incision, the posterior canal skin flap with inferior pedicle was created by two vertical and one horizontal incisions. Then the flap was rotated over the temporalis fascia graft. The graft success rate and postoperation hearing test results were evaluated in 52 patients who suffered from large tympanic membrane perforations.Results: We achieved a 92.3% total graft success rate with about 9 dB improvement in speech reception threshold (SRT).
Conclusion:The rotational inferior base posterior canal skin flap tympanoplasty technique is simple, fast, safe, and effective for the repair of subtotal tympanic membrane perforations.
Background: Chronic otitis media (COM) endures be an important health problem across the world. Unleashed usage of antibiotics caused development of resistant bacterial strains for infections such as COM as well. Useful antibiotics therapy should be selected according to especially susceptibility pattern of most common local organisms. Aim: The study was conducted from July 2018 to June 2019 in one referral otolaryngology surgical center in the south of Iran to determine the causative microorganisms, their antibiotic sensitivity pattern and occurrence of bacteremia in chronic otitis media patients undergoing tympanomastoidectomy. Patients and Methods: This study designed with eighty-seven samples from eighty-seven ears which were obtained from patients who suffer from chronic otitis media. aerobic culturing and antibiotic sensitivity testing were done with standard antibiotic discs using the National Committee for Clinical Laboratory Standards guidelines. Also, venous blood samples were taken before and after the operation for microbiological study. fun Chi-square test, t-test were used for the statistical analysis in this study. Results: No microorganisms were isolated from the preoperative and post-operative blood cultures. Out of 87 patients, microbiological culture was yielded from 51 specimens (58.6 %). Staphylococci coagulase negative (n=19, 37%) was the most common isolate followed by Staphylococci coagulase positive (n=12, 23%). Susceptibility pattern of Staphylococci spp. showed that almost 80% isolates were sensitive to Ciprofloxacin followed by almost 60% to Co-trimoxazole.
Conclusion:Our results proposed that bacteremia might not happen after tympanomastoidectomy. Continuous investigation of susceptibility pattern can improve the success of treatment process for chronic otitis media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
