Allergic shiners in a patient with cough-variant asthma: a case report

BACKGROUND

Chronic cough, with a duration of coughing of more than 8 weeks in adults, affects 5-10% of the general population. One of the most common causes of chronic cough is cough-variant asthma, which accounts for approximately one-third of cases. This phenotype of asthma is characterized by extreme sensitivity of the neuronal pathways mediating cough to environmental irritants, which results in an urge to cough. This case is an example of cough-variant asthma presenting with allergic shiners due to her severe cough.

CASE PRESENTATION

A 38-year-old Iranian woman, who was well before the start of the coronavirus disease 2019 pandemic, presented with a nonproductive hacking cough that had begun after excessive use of antiseptic solutions. The only positive finding on physical examination was a reddish-purple rash on and around the eyelids mimicking a heliotrope rash, which had probably evolved due to the severity of the cough. The results of the pulmonary function test were within normal limits. Methacholine challenge test and chest x-ray were both normal. Chest high-resolution computed tomography revealed hyperinflation and tree-in-bud opacities. All other laboratory tests were normal. Because of the reversibility in her pulmonary function test, despite normal baseline parameters, asthma treatment was initiated, resulting in disappearance of the cough and the eye discoloration, being indicative of the correct diagnosis and proper treatment.

CONCLUSION

Patients with cough-variant asthma may often have no other classic symptoms of asthma other than cough.

Assessment of aortic regurgitation mechanism with cardiac magnetic resonance: an echocardiography comparative study

Funding Acknowledgements

Type of funding sources: None.

Background

Aortic regurgitation (AR) quantification still remains challenging and requires an integrated approach. AR mechanism is one key parameter to take into account to assess its severity and repairability, and thus help to guide surgical decision. Although Cardiac Magnetic Resonance (CMR) has a growing interest in AR quantification, its performance to identify aortic AR mechanism has never been studied.

Purpose

We intended to define CMR Performance in this setting, by using echocardiography as reference.

Methods

AR mechanism was systematically evaluated in sixty-seven patients (81% male, mean age 46 ± 20 years) with chronic AR using CMR, and compared to transthoracic (TTE) and transesophageal (TEE) echocardiography as gold standard. AR were categorized as follows: type 1, aortic dilatation; type 2, Cusp prolapse; type 3, restrictive cusp motion. Jet direction, number of cusps and calcification (1 = no calcification, 2 = spots, 3 = big calcification interfering with cusp motion and 4 = Extensive with restricted cusp motion) were also evaluated.

Results

At TTE/TEE, mechanisms of AR were type 1 in 56 (83.5%), type 2 in 33 (49.2%), type 3 in 24 (35%). Agreement between TTE/TEE and CMR was modest, with respectively 74.6% (k= 0.4), 79.1% (k = 0.58) and 74.6% (k = 0.44). Bicuspid aortic valve was found in 44 (65.7%) patients at TTE/TEE, agreement with CMR was excellent, 98.5% (k = 0.97).  Jet was directed to the mitral valve in 42 (62.7%), at the inter ventricular septum in 12 (17.9%), and central in 13 (19.4%). Agreement with CMR was correct, respectively 80% (k = 0,6), 88% (k = 0.62) and 83.5% (K= 0.52). Calcification extension was 1 in 26 (38.8%), 2 in 25 (37.3%), 3 in 11 (16.4%) and 4 in 5 (7.5%). Agreement with CMR was poor, 44.7% (K= 0.28).

Conclusion

Accuracy between CMR and TTE/TEE to evaluate chronic AR mechanism and repairability was modest, with lower performance to define calcification extension.

Recurrent Periorbital Cellulitis Secondary to Cyclic Neutropenia

Purpose:

To present a 1-year-old boy with cyclic neutropenia who presented with multiple episodes of periorbital cellulitis (POC).

Methods:

The child presented with three episodes of POC. In the second episode, the cellulitis was associated with nasolacrimal duct obstruction, and in the third episode, a pansinusitis was noted. He underwent a thorough systemic evaluation.

Results:

Patient's evaluation revealed the diagnosis of cyclic neutropenia.

Conclusion:

This report emphasizes the possibility of an underlying immunodeficiency with recurrent POC, even in an apparently healthy child.

Paranasal sinuses computed tomography findings in anosmia of COVID-19

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.

Orbital cellulitis secondary to giant sino-orbital osteoma: A case report

Background

Although osteoma is a common benign tumor of the paranasal sinuses, its orbital extension is not common. Secondary orbital cellulitis has rarely been reported in association with sino‐orbital osteoma.

Case

A 30‐year‐old woman presented with left side proptosis, orbital pain and inflammation. Orbital CT scan showed a well‐defined giant osteoma in the superonasal part of the left orbit originating from the left ethmoidal sinus associated with opacity of the ipsilateral ethmoidal sinus and infiltration of orbital soft tissue. After treatment by systemic antibiotics, osteoma was resected with combined external and endoscopic surgery and the patient recovered uneventfully.

Conclusion

Sino‐orbital osteoma may manifest primarily as orbital cellulitis and needs early surgical intervention.

Emergence and Evolution of Olfactory and Gustatory Symptoms in Patients with COVID-19 in the Outpatient Setting

The present study aimed at evaluating the prevalence of general and sinonasal symptoms in patients with olfactory symptoms and mild coronavirus disease-2019 (COVID-19) and determining the patterns in emergence and resolution of olfactory/gustatory symptoms relative to general and sinonassal symptoms. This was a prospective cross-sectional study conducted at the outpatient otorhinolaryngology clinic at a COVID-19-designated referral Hospital. We included consecutive patients with new-onset olfactory dysfunction and positive polymerase chain reaction (PCR) assay of COVID-19. We asked the patients to fill in a questionnaire about general and sinonasal symptoms in association with anosmia, hyposmia or hypogeusia, and recorded the time course of the olfactory/gustatory symptoms during 2-weeks of follow-up. 76 patients with average age of 38.5 ± 10.6 years were included. Majority of participants (94.7%) had general or sinonasal symptom. There was anosmia in 60.5% and hyposmia in 39.5%, with sudden onset of olfactory symptoms reported in 63.2% of patients. During the follow-up, 30.3% of patients completely and 44.7% partially recovered from anosmia/hyposmia. Regardless of whether the general or olfactory symptoms appeared initially, the general symptoms resolved first while a degree of olfactory dysfunction persisted during the follow-up. Our study showed that hyposmia and anosmia in mild COVID-19 are frequently associated with general and sinonasal symptoms and tend to persist longer than the general and sinonasal symptoms during the course of the disease.

Anosmia and the Need for COVID-19 Screening during the Pandemic

In this commentary, we briefly summarize the available data from Iran and other countries on the sudden increase in anosmia, hyposmia, and hypogeusia that has coincided with the COVID-19 pandemic. Alarmingly, a high proportion of patients with severe COVID-19 had isolated anosmia as the sole initial presenting symptom, which is likely due to the direct neuropathic effect of the virus rather than being secondary to nasal congestion and obstruction. Since isolated anosmia is not yet considered a prerequisite for screening for COVID-19, we wish to raise awareness on the association of anosmia with COVID-19, urging international and national health authorities to consider this association in their efforts for early detection and isolation of infected individuals and for breaking the chain of transmission. We urge our colleagues who assess patients with new-onset anosmia to strictly adhere to the safety guidelines to reduce the risk of exposure and infection during this nascent pandemic.

Epidemiology of Nasopharyngeal Cancers in Iran: A 6-year Report

BACKGROUND

Nasopharyngeal cancer is a disease with distinct ethnic and geographical distribution. The aim of this review was to describe the epidemiological characteristics of nasopharyngeal cancer in Iran from 2004 to 2009 because no systematic study has been performed to evaluate the trends of its incidence yet.

MATERIALS AND METHODS

The data were derived from the databases of the National Cancer Data System Registry in the period of 2004-2009. Nasopharyngeal cancers were classified according to the International Classification of Diseases for Oncology. Incidence rates and trends were calculated and evaluated by gender, age decade, and histopathology types.

RESULTS

A total of 1,637 nasopharyngeal cancers were registered in Iran from 2004 to 2009 giving an incidence of 0.38 per 100,000. The male-to-female ratio was 2.08:1. The trend of incidence was found to have increased, with a significant increase observed in males. Undifferentiated carcinoma was the most common histopathology type in all the age decades.

CONCLUSIONS

Because the incidence of nasopharyngeal cancers in Iran has increased, especially in males, further studies are recommended for understanding of the etiological factors involved in the rise of the disease.

Incidence Trends and Geographical Distribution of Nasopharyngeal Carcinoma in Iran

BACKGROUND

Nasopharyngeal carcinoma (NPC) has known as a highly distinct kind of head and neck cancer. This distinction has been due to its clinical presentation, epidemiology, outcome, and treatment. There have not been any reports of epidemiological analysis of NPC in Iran. This study has evaluated the incidence rates and trends of nasopharyngeal carcinoma in the Iranian population during 2004 to 2009.

METHODS

The data have collected from the Iranian national cancer data system registry. All the cases of nasopharyngeal carcinoma (with the topography code 11 and histology of carcinoma) have retrieved and analyzed from an overall cancer database during a 6-year period. The data have analyzed by using the SPSS, version 16.

RESULTS

To determine the current incidence of NPC in Iran, we have examined the NPC cases from 2004 to 2009. A total of 1431 cases (981 male and 450 female NPC patients) have analyzed epidemiologically in this study. The mean age of the patients was 47.1 years. The incidence was 0.33 per 100000 persons. The overall incidence rate have increased annually (p<0.05). The incidence of NPC gradually increased with age. Prefectures that bordering the Caspian Sea have proved to have a higher incidence than the other studied areas.

CONCLUSION

Our study has indicated an increasing trend in the incidence of nasopharyngeal carcinoma. Therefore; attempts should be precipitated for prevention.
