Review Study

During ENT practice, we have to examine the nose and perform several nasal procedures in our clinics. Otolaryngologists are at a high risk of exposure to the COVID-19 virus. Nasal endoscopy is a major procedure for the diagnosis of the nasal and paranasal sinus diseases and introducing proper health services for our patients. In addition, the world is living the era of the COVID-19 pandemic, for which we have to protect ourselves, educate our medical staff, and work together against the spread of this severely contagious disease within our communities. The main purpose of this study is to review the protocol of nasal endoscopy in the ENT clinic and enhance the safest way to deal with patients during this pandemic.(1)

Acute Colonic Diverticulitis

Background & Aims: Diverticulitis is often diagnosed in outpatients, yet little evidence exists on diagnostic evidence and demographic/clinical features in various practice settings. We assessed variation in clinical characteristics and diagnostic evidence in inpatients, outpatients, and emergency department cases and effects of demographic and clinical variables on presentation features.Methods: In a retrospective cohort study of 1749 patients in an integrated health care system, we compared presenting features and computed tomography findings by practice setting and assessed independent effects of demographic and clinical factors on presenting features.Results: Inpatients were older and more often underweight/normal weight and lacked a diverticulitis past history and had more comorbidities than other patients. Outpatients were most often Hispanic/Latino. The classical triad (abdominal pain, fever, leukocytosis) occurred in 78 (38.6%) inpatients, 29 (5.2%) outpatients and 34 (10.7%) emergency department cases. Computed tomography was performed on 196 (94.4%) inpatients, 110 (9.2%) outpatients and 296 (87.6%) emergency department cases and was diagnostic in 153 (78.6%) inpatients, 62 (56.4%) outpatients and 243 (82.1%) emergency department cases. Multiple variables affected presenting features. Notably, female sex had lower odds for the presence of the triad features (odds ratio [95% CI], 0.65 [0.45-0.94], P<0.05) and increased odds of vomiting (1.78 [1.26-2.53], P<0.01). Patients in age group 56 to 65 and 66 or older had decreased odds of fever (0.67 [0.46-0.98], P<0.05) and 0.46 [0.26-0.81], P<0.01), respectively, while ≥1 co-morbidity increased the odds of observing the triad (1.88 [1.26-2.81], P<0.01).Conclusion: There was little objective evidence for physician-diagnosed diverticulitis in most outpatients. Demographic and clinical characteristics vary among settings and independently affect presenting features.Abbreviations: AD: acute colonic diverticulitis; BMI: body mass index; CT: computed tomography; ED: emergency department; IBS: irritable bowel syndrome; ICD-9-CM: International Classification of Diseases, 9th Revision, Clinical Modification; IP: inpatient; KPSC: Kaiser Permanente Southern California; OP: outpatient.

ABSTRACT Exostoses or hyperostoses are benign bony outgrowths originating from the cortical bone and depend on their location for a more precise designation. The most common types found in the oral cavity are the torus palatinus and the torus mandibularis. Buccal and palatal exostoses are located along the buccal aspect of the maxilla and/or the mandible (commonly in the premolar and molar areas) and on the palatal aspect of the maxilla (usually in the tuberosity area), respectively. The etiology of exostoses still hasn’t been enlightened but an interaction between environmental and genetic factors is accredited. They are usually asymptomatic, unless the mucosa becomes ulcerated. The frequency of exostoses increases with age, having their biggest prevalence from 60 years old, being more common in men and suffering ethnic influences. A thorough evaluation is important for the correct diagnosis since other lesions have similar clinical characteristics to the exostoses such as osteomas. The majority of exostoses are diagnosed clinically along with radiographic interpretations, making the biopsy dispensable and the treatment is usually unnecessary. The aim of this article was to describe a case report of bilateral maxillary exostosis, unusual, in a female patient. If an excessive amount of bone is present the exostoses may exhibit a relative radiopacity on dental radiographs. Initially, periapical and panoramic radiographs were performed to evaluate the alterations. Due to the size of the exostoses a concomitant Cone Beam Computed Tomography was performed to confirm the diagnosis. The patient is in follow-up.

Abstract Background Chondrosarcoma(ChSa) is a rare malignant tumor. But it’s necessary to discuss the clinical characteristics and treatments for ChSa of paranasal sinus and the skull base. Methods The clinical characteristics of ChSa of paranasal sinus and skull base in 10 patients (6 males and 4 females) from 2001 to 2017 were analyzed. They all underwent by endoscopic surgery . The patients’ age ranged from 18 to 47 years, with a median of 35 years. Clinical symptoms: stuffy, nose bleeding, runny, headache, diplopia, eye outreach limited, blurred vision and even blindness. Surgery methods：under nasal endoscopy, after the attachment sites of the tumors to normal tissues were confirmed, the tumors were peeled off along the clear boundary between the tumors and normal tissues, and the potential residual tumor tissues on bones were cleared by a drill. Results All patients were treated with endoscopic surgery，followed up postoperatively for 24 to 108 months, with a median of 36 months. 8 of 10 patients were no recurrence,2 were alive with tumor. Conclusion ChSa of paranasal sinus and skull base can be treated by nasal endoscopic surgery with good clinical results.
