SummaryOtomycosis is a recognized clinical entity in the tropical regions of the world. However, there is scanty information on this disease in some parts of Sub-Saharan Africa. The aim of this study was to determine the prevalence and pattern of etiological agents of otomycosis in western Nigeria. Medical records of patients with otomycosis seen in the Otorhinolaryngology Department of the University College Hospital, Ibadan from 1996-2005 were reviewed for all essential clinical data. Of the 5784 patients with ear diseases, 378 (6.54%) had otomycosis which consisted of 145 (38.36%) males and 233 (61.64%) females. Seventeen patients (4.50%) had recurrence within six months of treatment, 4 (1.06%) had poorly controlled plasma glucose. A significant number of our patients, 52 (13.76%), had prior topical aural antibiotic treatment following misdiagnosis. The predominant etiological agents in our series were Aspergillus niger (48.35%) and Aspergillus fumigatus (33.96%).

Objective Loss of smell and taste are considered potential discriminatory symptoms indicating triaging for coronavirus disease 2019 (COVID-19) and early case identification. However, the estimated prevalence essential to guide public health policy varies in published literature. This meta-analysis aimed to estimate prevalence of smell and taste loss among COVID-19 patients. Data Sources We conducted systematic searches of PubMed, Embase, Web of Science, and Google Scholar databases for studies published on the prevalence of smell and taste loss in COVID-19 patients. Review Methods Two authors extracted data on study characteristics and the prevalence of smell and taste loss. Random-effects modeling was used to estimate pooled prevalence. Subgroup analysis and meta-regression were conducted to explore potential heterogeneity sources. This study used PRISMA and MOOSE guidelines. Results Twenty-seven of 32 studies reported a prevalence of loss of smell, taste, or both from a combined sample of 20,451 COVID-19 patients. The estimated global pooled prevalence of loss of smell among 19,424 COVID-19 patients from 27 studies was 48.47% (95% CI, 33.78%-63.29%). Loss of taste was reported in 20 studies and 8001 patients with an estimated pooled prevalence of 41.47% (95% CI, 3.13%-31.03%), while 13 studies that reported combined loss of smell and taste in 5977 COVID-19 patients indicated a pooled prevalence of 35.04% (95% CI, 22.03%-49.26%). Conclusions The prevalence of smell and taste loss among COVID-19 patients was high globally, and regional differences supported the relevance of these symptoms as important markers. Health workers must consider them as suspicion indices for empirical diagnosis of severe acute respiratory syndrome coronavirus 2 infection.

IntroductionThis study is aimed at determining the pattern of ear, nose and throat diseases and their relationship with socio-demographic factors with auditing intent in a tertiary hospital in South-western Nigeria.MethodsMedical records of patients managed at the Department of Otorhinolaryngology, University College Hospital, Ibadan, Nigeria from 2006 to 2010 were reviewed for all essential clinical data.ResultsThere were 2641 (52.8%) males and 2360 (47.2%) females. Two thousand and fifty (41%) patients had age ≤15years old. Sixty three percent of the patients were Christians, 37% were Muslims and less than 1% had other religions. There were more patients in lower occupational classes than those in the upper classes. The average number of patients with ear, nose and throat diseases managed per month was eighty three. Patients with ear diseases were 3136 (62.7%), the nose diseases were 1153 (23.0%), the throat diseases were 479 (9.6%) and head/neck diseases were 233 (4.7%).ConclusionThis study showed that otitis media, obstructive adenoid, foreign bodies in the ear and throat infections were the common ear, nose, throat disorders seen in patients aged ≤15years whereas, hearing loss, rhinosinusitis and tumors were the common disorders of ear, nose and throat seen in patients aged 16 years and above. Although these disorders are not yet considered to be of public health importance, they contribute significantly to the existing burden of health problems in our environment. Therefore, there is a need for improved public awareness on ear, nose and throat diseases.

This study shows in a vivid way that phleboliths from VM of the head and neck area show a laminar structure and consist of apatite, without any indication of differences in their chemical composition. Treatment of localized intravascular coagulopathy in VM might be able to prevent the formation and the progression of phleboliths. Hypothetically, another option might be lithotripsy.

IntroductionSymptomatology, nasal endoscopy and Computerised Tomographic (CT) scan have been used to diagnose chronic rhinosinusitis. The value of disease severity score in the assessment of chronic rhinosinusitis has not been well investigated. Hence, this study aims to correlate the pre-operative symptom severity score as well as overall disease severity scoreof patients with chronic rhinosinusitis with CT scan scores.MethodsThis is a prospective study of 60 patients diagnosed clinically with chronic rhinosinusitis. Each patientsubjectively assessed his/her presenting symptoms and severity of disease on a visual analogue scale. The patients had CT scan of the paranasal sinuses which were graded and scored using Lund-Mackay grading system. The correlation study between severity of symptoms/disease severity and CT scores was performed. The level of statistical significance was considered at p < 0.05 and confidence interval at 95%.ResultsAll patients had more than one symptom with mean symptom severity scores highest for nasal discharge and nasal obstruction. There was a significant correlation between CT scores and nasal discharge (r = -0.132; p = 0.03)and nasal obstruction (r = 0.193; p = 0.049). No correlation with other symptoms. There wasno correlation between the overall disease severity scores and the Lund-Mackay CT scores (r = 0.195; p = 0.6).ConclusionThis study showed that CT scan scores can help clinicians to predict severity of symptom for nasal obstruction and discharge but not for other symptoms of chronic rhinosinusitis. However, there was no association of CT score with the overall disease severity score.
