The place of 18F FDG PET/CT in the management of patients with eosinophilic fasciitis: a case report.

Eosinophilic fasciitis is a rare connective tissue disease with a clinical presentation of scleroderma-like disease. We report a case of a 36-year-old female patient with a 6-month history of progressive stiffness involving her forearms and legs with joint pain. Laboratory examinations showed hypereosinophilia and elevated C-reactive protein. 18F FDG PET/CT showed diffuse and symmetrical increased uptake in the fasciae of the upper and lower limbs, sparing both muscles and fat tissues. Guided biopsy and histologic examination confirmed the diagnosis of eosinophilic fasciitis. 18F FDG PET/CT is of great help in the diagnosis of eosinophilic fasciitis, as it can guide the biopsy where FDG uptake is strongest and also help rule out possible associated neoplasms.

Psychological impact of the SARS-CoV-2 outbreak on the staff of a French hospital.

Background: The outbreak of SARS-CoV-2 has resulted in anxiety, depression and post-traumatic stress disorder (PTSD) among hospital staff. The factors associated with this psychological impact remain to be determined. Methods: A cross-sectional study using an online questionnaire completed by the staff of a French hospital, two months after the SARS-CoV-2 outbreak. Results: Among the 353 participants (of whom 67% were healthcare professionals), 32% had symptoms of anxiety, 16% of depression and 16% of PTSD. Eleven per cent had initiated or increased treatment with sleeping pills, and 6% with anxiolytics. In a multivariate analysis, factors independently associated with anxiety were: change of professional team, having a relative infected by SARS-CoV-2 and a new/increased treatment with sleeping pills or anxiolytics. The only factor associated with depression was the feeling of risk during professional practice. The factors associated with PTSD were: having a relative infected by SARS-CoV-2, the feeling of risk during professional practice, the increase in smoking and treatment with sleeping pills. The observance of transmission preventive measures (TPM) was not associated with the psychological impact of SARS-CoV-2. A personal history of SARS-CoV-2 infection and age < 36 years were associated with insufficient use of protective equipment. Age < 36 years, and being a healthcare professional were associated with the non-observance of social distancing. Conclusion: The hospital staff displayed psychological consequences, resulting in the use of anxiolytics and sleeping pills. Belonging to a group with low-risk of severe disease was associated with lower observance of TPM.

Extreme hyperferritinemia: etiological spectrum and impact on prognosis.

Hyperferritinemia can be the result of inflammation, infection, iron overload, or other uncommon pathologies including hemophagocytic lymphohistiocytosis (HLH). The significance of its elevation and its association with poor prognosis and critical clinical situations is unclear. To study the spectrum of diagnosis associated with elevated serum ferritin, we made a retrospective review of patients admitted to our center from 2015 and 2017 with serum ferritin levels above 2000 µg L-1. The H score was retrospectively assessed in all cases to evaluate the possible presence of HLH. The degree of ferritinemia found was compared with the evaluation of the undelying diagnosis and the results of laboratory examinations. A total of 77 patients were identified with a serum ferritin level >2000 µg L-1. Hematological malignancy was the most prevalent diagnosis with n=20; severe infection was next with n=14. Eleven patients were diagnosed with HLH. The hemophagocytosis pictures on bone marrow smear and mortality rate were significantly correlated with ferritin level above 6000 µg L-1 (p<0.01). The comparison of the HLH subgroup with the rest of the cohort showed that fever, cytopenia (anemia, leucopenia, neutropenia and thrombocytopenia), hemophagocytosis pictures, and major liver disturbances were significantly increased in the HLH subgroup. The H score was significantly elevated in the subgroup of patients with ferritin above 6000 µg L-1, with a significatively higher probability of HLH (p<0.01). The mortality rate at 3 months was significantly increased in the HLH subgroup. Extreme hyperferritin cannot be considered as a specific marker for the diagnosis. The cut off of 6000 µg L-1 is significantly associated with HLH diagnosis. The H score is an interesting screening tool that physicians should use to rule out the probability of HLH when facing critical clinical situations.

Erysipelas-like presentation of Wells' syndrome (eosinophilic cellulitis).

Wells' syndrome, also called eosinophilic cellulitis, is a rare eosinophilic dermatosis characterized by an unspecific inflammatory erythematous eruption often associated with systemic symptoms. Here we report the case of a 57-year-old female with bilateral painful pitting and pruritic feet progressive for two weeks despite one week of oral antibiotics. Skin biopsy was performed showing dermal eosinophilic infiltration. The patient showed a spontaneous progressive improvement of the condition. The presented case demonstrates both clinical and histologic presence of lesions of Wells' syndrome in the course of the disease. A careful diagnostic approach is needed because of the lack of specific signs. The global outcome is favorable and spontaneous resolution is possible.

A rare cause of abdominal pain: Fibromuscular dysplasia.

A 50-year-old man had a sudden severe abdominal pain. An abdominal enhanced computed tomographic scan revealed irregular stenosis of the celiac artery, dissection of the hepatic artery and of the left common iliac artery, and mid stenosis of the right renal artery with extended renal parenchymal hypodensity. After careful evaluation, the patient was diagnosed with fibromuscular dysplasia. Systematic head and neck CT angiography revealed right vertebral arterial stenosis and saccular aneurysm of the left vertebral artery. We have chosen conservative medical treatment for the multifocal fibromuscular dysplasia.

Case of disseminated histoplasmosis in a HIV-infected patient revealed by nasal involvement with maxillary osteolysis.

BACKGROUND: Disseminated Histoplasmosis (DH) is a rare manifestation of Acquired Immune Deficiency Syndrome (AIDS) in European countries. Naso-maxillar osteolysis due to Histoplasma capsulatum var. capsulatum (Hcc) is unusual in endemic countries and has never been reported in European countries. Differential diagnoses such as malignant tumors, cocaine use, granulomatosis, vasculitis and infections are more frequently observed and could delay and/or bias the final diagnosis. CASE PRESENTATION: We report the case of an immunocompromised patient infected by Human Immunodeficiency Virus (HIV) with naso-maxillar histoplasmosis in a non-endemic country. Our aim is to describe the clinical presentation, the diagnostic and therapeutic issues. A 53-year-old woman, originated from Haiti, was admitted in 2016 for nasal deformation with alteration of general condition evolving for at least 6 months. HIV infection was diagnosed in 2006 and classified at AIDS stage in 2008 due to cytomegalovirus infection associated with pulmonary histoplasmosis. At admission, CD4 cell count was 9/mm3. Surgical biopsies were performed and ruled out differential or associated diagnoses. Mycological cultures identified Hcc and Blood Polymerase Chain Reaction (PCR) for Hcc was positive. The patient was given daily Amphothericin B liposomal infusion during 1 month. Hcc PCR became negative in the blood under treatment, and then oral switch by itraconazole was introduced. Antiretroviral treatment was reintroduced after a 3-week histoplasmosis treatment. Normalization of naso-maxillar mucosa enabled a palatal prosthesis. CONCLUSION: Naso-maxillar histoplasmosis is extremely rare; this is the first case ever reported in a non-endemic country. Differential diagnoses must be ruled out by conducting microbiologic tools and histological examinations on surgical biopsies. Early antifungal treatment should be initiated in order to prevent DH severe outcomes.

Descending necrotizing mediastinitis as a complication of odontogenic infection.

Descending necrotizing mediastinitis (DNM) is a serious, life threatening complication that can occur from a common odontogenic infection. Even with advancements in antibiotics, diagnostic imaging, and surgical management, the mortality rate remains between 20 and 40%. It is imperative that the practitioner taking care of patients with odontogenic infections be sensitized to this potentially fatal complication. We report the successful management of a case of mediastinitis complicating an odontogenic infection in a 39-year-old male.
