A Case of Unilateral Proptosis Secondary to Prostatic Metastasis.

Prostate cancer metastases involving the orbit and/or paranasal sinuses represent a rare oncological presentation. Patients can have a myriad of symptoms such as proptosis, periorbital swelling, blurry vision, rhinorrhea, epistaxis, anosmia, or others depending on the structures involved. The differential diagnosis of paranasal sinus masses on imaging studies is broad and can include inflammatory, congenital, or neoplastic masses; leading to the requirement of biopsy for definitive diagnosis. Tissue sample is usually obtained via an endoscopic approach. The prognosis of such a presentation is not well described in the literature, but it is usually guarded due to the advanced stage of the disease and generally a poorly differentiated primary tumor. Treatments usually aim to reduce the burden of disease and debulk the tumor mass for palliative purposes. We present a case of a 71-year-old male presenting with unilateral proptosis and periorbital swelling secondary to prostatic metastasis.

Conducting an Endoscopic Sinus Surgery Dissection Course via Telesimulation: An Initial Experience.

Objective: Medical education has been severely disrupted by the COVID-19 pandemic, with many in-person educational activities transitioned to distance learning. To overcome this challenge, we utilized telesimulation to conduct an endoscopic sinus surgery (ESS) dissection course. Our objectives were to evaluate the effectiveness and acceptability of telesimulation as an alternative to in-person dissection courses for resident training. Study Design: Cross-sectional study. Setting: Academic medical centers. Methods: The course, consisting of lectures and hands-on dissection, was conducted entirely over the Zoom platform. The participants were allocated outpatient clinic rooms at 2 hospitals, while the instructors supervised remotely. We utilized the camera systems in the clinics and 3-dimensional-printed sinus models for the dissection. Laptops with cameras were used to capture the endoscopic image and the dissector. We evaluated the effectiveness of telesimulation, the surgical skills of the participants, and the course by way of pre- and posttest and a questionnaire. Results: A total of 8 participants and 7 instructors participated in the study. Telesimulation was found to be effective in helping participants gain knowledge and skills in ESS. All participants improved on their pretest scores (31.5% vs 73.4%, P = .003) and felt more comfortable with ESS postcourse (1.9 vs 3.2, P = .008). Participants and instructors opined that telesimulation is an acceptable alternative to in-person dissection courses. Conclusion: Telesimulation is an effective, acceptable, and viable alternative to in-person dissection courses. It also has the advantage of overcoming temporal and geographic constraints to surgical training in residency.

Intranasal Steroid Use and Satisfaction in Allergic Rhinitis: A Cross-Sectional Study from an Asian Perspective.

BACKGROUND: Intranasal steroid (INS) is the most effective medication class for controlling allergic rhinitis (AR) symptoms; however, its effectiveness is limited by patient compliance. Previous studies have explored INS use, compliance, satisfaction, and experience. There is, however, no Asian study on these factors in entirety. OBJECTIVE: We aimed to investigate the rate of compliance to usage of INS and explore the reasons for noncompliance in our local population. METHODS: We conducted a prospective cross-sectional study on 65 AR patients in a tertiary hospital. Recruited patients were administered a questionnaire to collect data about symptoms, INS use, and concerns they may have. Statistical analysis was performed using SPSS. RESULTS: The overall compliance rate to INS was 63.1%. Noncompliance was associated with increased frequency of dosing (p = 0.050), presence of sensory attributes (p = 0.041), and forgetfulness (p = 0.049). The top 3 most frequent sensory attributes experienced by patients include throat rundown (29.2%), aftertaste (21.5%), and immediate taste (20.0%). There was a significant difference between brands of INS with regard to sensory attributes experienced (p = 0.003) but no side effects (p = 0.070). CONCLUSIONS: Identifying risk factors for noncompliance to INS can help health-care providers address difficulties faced by patients and hence increase compliance, allowing better control of AR symptoms.

A Systematic Review of the Omohyoid Muscle Syndrome (OMS): Clinical Presentation, Diagnosis, and Treatment Options.

OBJECTIVE: Omohyoid muscle syndrome (OMS) is a condition that causes a X-shaped lateral neck lump on swallowing, caused by the failure of the central tendon of the omohyoid muscle to restrict movement of the muscle during swallowing. We aim to review the etiology, pathophysiology, diagnostic tests, and management options for this condition. DATA SOURCES: Pubmed, MEDLINE, EMBASE, and Cochrane databases were searched for all articles and abstracts related to OMS up to 29th July 2020. REVIEW METHODS: A systematic review was performed, data extracted from relevant full text articles. Both quantitative data and qualitative data were analyzed. RESULTS: Twenty cases of OMS were reported. Patients presented at a mean age of 36.0. All cases were Asian. There is a 7:3 ratio of males to females. The most common symptom was a transient neck mass. Most cases were managed conservatively with good prognosis. Open or endoscopic transection of the muscle and ultrasound-guided botulinum toxin injection were 3 treatment options, with no recurrence at 4 years, 6 months, and 6 months respectively. CONCLUSION: OMS could be genetic as all cases were Asian in ethnicity. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20% of cases had a preceding traumatic event. Real-time ultrasonography establishes the diagnosis, demonstrating the anterolateral displacement of the sternocleidomastoid muscle by a thickened omohyoid muscle during swallowing. Surgical transection can achieve cure, but due to limited studies available, they should be reserved for patients who are extremely bothered. Intramuscular injection of botulinum toxin is an effective alternative, but recurrence is expected.

Olfactory taste disorder as a presenting symptom of COVID-19: a large single-center Singapore study.

PURPOSE: To investigate the prevalence and epidemiological risk factors of olfactory and/or taste disorder (OTD), in particular isolated OTD, in patients with laboratory-confirmed COVID-19 infection. METHODS: We conducted a retrospective and cross-sectional study. Patients with laboratory-confirmed COVID-19 infection were recruited from the National Centre for Infectious Diseases (NCID) Singapore between 24 March 2020 and 16 April 2020. The electronic health records of these patients were accessed, and demographic data and symptoms reported (respiratory, self-reported OTD and other symptoms such as headache, myalgia and lethargy) were collected. RESULTS: A total of 1065 patients with laboratory-confirmed COVID-19 were recruited. Overall, the prevalence of OTD was 12.6%. Twelve patients (1.1%) had isolated OTD. The top three symptoms associated with OTD were cough, fever and sore throat. The symptoms of runny nose and blocked nose were experienced by only 29.8 and 19.3% of patients, respectively. Multivariate analysis demonstrated that the female gender, presence of blocked nose and absence of fever were significantly associated with OTD (adjusted relative risks 1.77, 3.31, 0.42, respectively). All these factors were statistically significant. CONCLUSION: Patients with COVID-19 infection can present with OTD, either in isolation or in combination with other general symptoms. Certain demographic profile, such as being female, and symptomatology such as the presence of blocked nose and absence of fever, were more likely to have OTD when infected by COVID-19. Further studies to elucidate the pathophysiology of OTD in these patients will be beneficial.

Cultivating social occupations, spaces, and networks: service providers' perspectives on enabling immigrants' social participation / Cultivando ocupações sociais, espaços e redes: as perspectivas dos prestadores de serviços sobre como possibilitar a participação social dos imigrantes

Abstract Introduction Immigrants may experience many barriers to social participation within host societies. Immigrants' integration into Canadian society is supported through government-funded services. Objective In the present study, we explored the perspectives of service providers working in community organizations regarding their role in enabling immigrants' social participation through occupations in British Columbia, Canada. Method Representatives from twenty different organizations providing services to the community participated in a constructivist qualitative study aiming to uncover aspects shaping opportunities for occupational participation provided for immigrants. Results Drawing on semi-structured interviews and using thematic analysis, we identified three main themes relating to cultivating social occupations, spaces, and networks. Findings illustrate that service providers' cultivation of these opportunities can support immigrants' desired social roles and social identities, further enabling their participation in receiving societies. Conclusion Emphasis upon supporting socio-economic integration into society appears to limit a client-centred approach to developing opportunities for social participation through occupation. Implications for occupational therapists and scientists are discussed.

Oral Neurothekeoma of the Right Buccal Mucosa.

Oral neurothekeoma or nerve sheath myxoma is a rare benign oral tumour of nerve sheath origin. Historically, this tumour has been subclassified as myxoid (classic), mixed, or the cellular type, depending on the amount of myxoid stroma and cellularity. We present a case of oral neurothekeoma (mixed type) of the buccal mucosa. The tumour was completely excised. No recurrence was detected in the last 3 years after local excision.

Clinical spectrum of microsporidial keratoconjunctivitis.

The purpose of this paper was to analyse the causes, pathogenesis, diagnostic modalities and treatment outcomes of microsporidial keratoconjunctivitis (MKC). Microsporidia are increasingly recognized as opportunistic infectious pathogens in immunocompromized patients causing keratoconjunctivitis. In the recent years, there has been a surge in reports of MKC in immunocompetent individuals presenting with stromal keratitis. A detailed literature search was done using Medline, OVID, Cochrane Library, UptoDate and Google Scholar databases with the terms microsporidia, keratitis, conjunctivitis, immunocompromized and immunocompetent. The articles were reviewed to determine the spectrum of clinical presentation, disease course, investigations, treatment modalities and outcome. Thirty-six publications were reviewed, and 151 cases of MKC were included for this review. The main presenting features included pain, redness, photophobia, epiphora and blurring of vision. Duration of the symptoms lasted between 4 days and 18 months. Light microscopy with modified trichrome stain was most commonly used to diagnose MKC. Resolution of symptoms was most commonly achieved with oral albendazole and/or topical fumidil B. Topical fluoroquinolones are also effective as a monotherapy as suggested by recent studies. Clinical outcome was good (visual acuity ≤ 6/12) for the patients who presented earlier (≤1 month) (75% of cases with documented final best-corrected visual acuity). MKC occurs more commonly in immunocompetent individuals than expected and can be diagnosed in earlier stages. From our review, we conclude that the patients, who were diagnosed early and treated, had complete resolution of symptoms with a better clinical outcome.
