You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["HealthCareActivity", "InjuryOrPoisoning", "BodySubstance", "IntellectualProduct", "AnatomicalStructure", "SpatialConcept", "Chemical", "Bacterium", "MedicalDevice", "Organization", "BiomedicalOccupationOrDiscipline", "Finding", "BiologicFunction", "Virus", "ResearchActivity", "ClinicalAttribute", "PopulationGroup", "Eukaryote", "BodySystem", "Food", "ProfessionalOrOccupationalGroup"].

Please return the output as a JSON object of the format: {"Virus": ["HIV", ...], "Bacterium": ["MRSA", ...], "AnatomicalStructure": ["Lung", ...], "BodySystem": ["CNS", ...], "BodySubstance": ["Serum", ...], "Finding": ["Headache", ...], "InjuryOrPoisoning": ["Fracture", ...], "BiologicFunction": ["Death", ...], "HealthCareActivity": ["Biopsy", ...], "ResearchActivity": ["Clinical trial", ...], "MedicalDevice": ["Lenses", ...], "SpatialConcept": ["Camps", ...], "BiomedicalOccupationOrDiscipline": ["Forensic medicine", ...], "Organization": ["WHO", ...], "ProfessionalOrOccupationalGroup": ["Provider", ...], "PopulationGroup": ["Swimmers", ...], "Chemical": ["Gold", ...], "Food": ["Rice", ...], "IntellectualProduct": ["RPAM", ...], "ClinicalAttribute": ["Biomarker", ...], "Eukaryote": ["Dogs", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Acute Complicated Sinusitis: Ten Years Experience from the University Hospital of the West Indies Complicated sinusitis is rare. It might not be identified early and might expose the patient to an unfavourable outcome. There is a paucity of data regarding this condition in the Caribbean. This study was undertaken to describe the clinical characteristics and treatment outcomes of patients admitted with this condition. A retrospective chart review was performed on patients admitted to the University Hospital of the West Indies (UHWI) with complicated sinusitis between 1999 to 2011. The data was analysed using SPSS statistics 22 software. There were 30 patients (23 males and 7 females). The mean (SD) age was 19 (13.96) years. Twenty-two had orbital complications, two had intracranial complications and one had both. The most common organisms isolated were streptococcus and the most common sensitivity was to amoxicillin and clavulinic acid. Sixteen patients who had an external surgical approach had a mean (SD) hospital stay of 8.8 (3.71) days compared to three patients who had a purely endoscopic approach who had a mean (SD) hospital stay of 7.67 (0.577) days. There was no statistical difference in mean hospital stay between these two groups (95% CI,-3.49-5.78; p = 0.609). The mean duration of hospital stay for those treated medically was six days versus ten days for the surgical group. The mean difference was three days (95% CI, 0.193-6.595; p = 0.039). Acute complicated sinusitis is seen more commonly in adolescent males. The most common complication was orbital. Surgical treatment is indicated for those patients who fail medical management and should consist of an endoscopic approach which may be combined with open approaches if indicated.
