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:

Urticarial exanthema due to hepatitis B in a pregnant woman, mimicking a polymorphic eruption of pregnancy Hepatitis B virus (HBV) infection in pregnant women is very rare in western countries, thus, cutaneous manifestation of HBV infection may be confused with a dermatosis specific of pregnancy. We report a 39-year-old woman who presented in her 20th week of pregnancy with a pruritic rash, which consisted of generalized erythematous plaques, some of them with a purple centre. Serology testing showed acute HBV infection, and a biopsy revealed a superficial and interstitial perivascular inflammatory infiltrate of lymphocytes and eosinophils. A diagnosis of exanthema due to acute hepatitis B infection was established. The patient delivered a clinically healthy boy, who was given the first dose of the HBV vaccine and intravenous specific immunoglobulin, followed by the second dose 2 months later, and did not get infected with HBV. To our knowledge, this is the first case describing HBV exanthema in a pregnant woman, which led to early action for the newborn, avoiding vertical transmission and its high prevalence of cirrhosis and hepatocellular carcinoma.
