Objective Olfactory dysfunction in coronavirus disease-2019 (COVID-19) is poorly understood. Thus, mechanistic data are needed to elucidate the pathophysiological drivers of anosmia of COVID-19. Methods We performed the current study in patients who presented with anosmia and COVID-19 as documented by the polymerase chain reaction (PCR) assay between April 1st and May 15st, 2020. We assessed for the conductive causes of anosmia with computed tomography (CT) of paranasal sinuses. Results 49 patients who presented with anosmia and positive PCR assay for COVID-19 were included. The average age was 45 ± 12.2 years. Complete anosmia was present in 85.7% of patients and 91.8% of patients reported sudden onset of olfactory dysfunction. Taste disturbance was common (75.5%). There were no significant pathological changes in the paranasal sinuses on CT scans. Olfactory cleft and ethmoid sinuses appeared normal while in other sinuses, partial opacification was detected only in some cases. Conclusion We did not find significant mucosal changes or olfactory cleft abnormality on CT imaging in patients with anosmia of COVID-19. Conductive causes of anosmia (i.e., mucosal disease) do not seem play a significant role in anosmia of COVID-19.

Coronavirus disease 2019 (COVID-19) first emerged in Wuhan, China, in December 2019. Since that time, the frequency of bacterial and fungal coinfections has been continuously increasing. Although invasive pulmonary aspergillosis is being increasingly recognized in association with COVID-19, there is limited information regarding COVID-19-associated mucormycosis. We describe a 50-year-old woman with uncontrolled diabetes who received systemic corticosteroids and remdesevir during her admission for COVID-19. A few days after discharge, the patient was readmitted because of facial swelling and numbness, and a diagnosis of COVID-19-associated rhinosinusitis mucormycosis caused by Rhizopus arrhizus (formerly called Rhizopus oryzae) was confirmed with sequencing of the internal transcribed spacer region of the ribosomal DNA. This report aimed to address the importance of short-term follow-up for COVID-19 patients who have received systemic corticosteroids, particularly those with predisposing conditions, because early detection and prompt, aggressive treatment are essential for the management of invasive fungal infections.

The purpose of this study was to investigate the models and tools used for the obstetrician-gynecologists (OB-GYNs) workforce planning and to determine the factors affecting their supply and demand. Methods: This systematic review was conducted by searching the relevant papers published in reputable electronic databases such as PubMed, Scopus and gray literature from 1980 to 2019. PRISMA model was employed to select the papers. The data were extracted by an author-made form and analyzed using framework content analysis method. Results: Considering the inclusion and exclusion criteria, a total of 45 papers were selected. A variety of factors and models were employed in the reviewed papers for the OB-GYNs workforce planning. The extracted data were classified under three categories: models, supply factors, and demand factors. Conclusion: The reviewed papers had made more accurate estimates through various variables, scenarios and different mathematical and simulation models. Therefore, the human resources for health (HRH) planners are recommended to consider all effective factors in order to improve the quality of future workforce estimations.

ObjectiveSinusitis is a common complaint in children with cystic fibrosis. However, the actual prevalence of chronic rhinosinusitis and its effect on the quality of life of children have not been well considered. Therefore, the objective of this study was to determine the effect of sinonasal quality of life in children with cystic fibrosis.Materials and methodsThis study was a diagnostic study performed on 80 children with cystic fibrosis ranging from 2 to 20 years old, who were referred to the cystic fibrosis clinic of Masih Daneshvari Hospital from 2017–2018. The questionnaires used in this study were chronic rhinosinusitis screening questionnaire based on the European task force and the evaluation of the sinonasal quality of life was based on the SN-5 survey.ResultsOf the 80 patients with fibrosis from 2 to 20 years old who were recruited in the study, 41 patients were female (51.3%) and 39 were male (48.8%). In 61 cases (76.3%), there was no chronic rhinosinusitis and 19 cases (23.8%) had chronic rhinosinusitis. The mean SN-5 score in 19 patients with chronic rhinosinusitis was 3.4105 and the mean score of patients without rhinosinusitis was 1.8426, with a P-value of 0.000. The mean SN-5 score was significant between the two groups. In patients with nasal congestion, there was a significant difference in quality of life factors such as sinus infection, nasal obstruction, and allergy symptoms (P<0.001). In patients with facial pain, there was a significant difference in quality of life factors such as sinus infection, nasal obstruction, allergic symptoms, and physical activity limitation (P <0.001). There was also a significant difference in the quality of life factors such as sinus infection, nasal obstruction, and allergy symptoms in patients with postnasal drip (P <0.001).ConclusionIn children with cystic fibrosis, the quality of life of sinonasal has a significant relationship with absence of chronic rhinosinusitis. This study showed that children with chronic renosinusitis have significantly lower quality of sinonasal life than children with chronic rhinosinusitis. The results demonstrated that quality of life scores in sinus infections, nasal obstruction, and allergy symptoms were significantly higher in patients with chronic rhinosinusitis than in those without chronic rhinosinusitis. The findings of this study are important for improving children’s health related quality of life, as it leads to promoting communication between the patient and the health care provider, identifying overlooked problems, monitoring the progress of the disease and the burden of treatment, and promoting interventions in the daily life of patients.
