Heerfordt syndrome with unilateral facial nerve palsy: a rare presentation of sarcoidosis.

BACKGROUND: Heerfordt syndrome is rare and is characterized by fever, uveitis, parotid gland enlargement, and facial nerve palsy. We hereby present a case of Heerfordt syndrome with unilateral facial nerve palsy as a presentation of sarcoidosis. HISTORY AND SIGNS: A 29-year-old male patient from Sri Lanka presented with eye redness OU, blurred vision OD, fever, headache, night sweat, fatigue, and weight loss (5 kg over 1 month). Examination revealed mild anterior uveitis OU, mild vitritis OD, fundus whitish lesions OU, left otalgia, taste disorders, bilateral parotid gland enlargement, and left facial nerve palsy. Work-up for infection or tumour was negative. Chest computed tomography and transbronchial lymph node biopsy set the diagnosis of sarcoidosis. THERAPY AND OUTCOME: The patient recovered completely within 2 months under therapy with prednisone and azathioprine. One year after onset of treatment, no recurrence was noted. CONCLUSIONS: Heerfordt syndrome is a rare manifestation of neurosarcoidosis and has to be included in the differential diagnosis of facial nerve palsy.

Polyarthrite rhumatoïde du sujet agé: présentation clinique et prise en charge [Late-onset rheumatoid arthritis: clinical presentation and management]

Onset of rheumatoid arthritis in an elderly patient is common, in fact more common than in younger subject. If the reality of true differences in clinical presentation between younger and older subjects remained discussed, the central point remains that the prognosis is not better in older patients. Finally, conventional disease-modifying antirheumatic drugs (DMARD) and biological treatments are as efficient and safe than in younger patients, and the same strict management objectives used for younger subjects must be applied in the elderly.

Purpura of the face and neck: an atypical clinical presentation revealing a hepatosplenic T cell lymphoma

BACKGROUND: Hepatosplenic T cell lymphoma (HSTL) is a rare but very aggressive peripheral T cell lymphoma whose initial silent clinical presentation unfortunately delays the diagnosis and worsens the prognosis of patient survival. Efforts should be aimed at early recognition and treatment. METHODS: We describe a case of a 62-year-old woman who presented at our clinic with a non-palpable purpuric eruption of the face. Investigations revealed thrombocytopenia with hepatosplenomegaly, which showed rapid progression together with accentuation of the purpura. Two months later, a bone marrow biopsy revealed the diagnosis of a HSTL. RESULTS: The patient received six cycles of CHOP chemotherapy (vincristine, cyclophosphamide, doxorubicin, methylprednisolone) followed by a well-tolerated autologous bone marrow graft. Normalization of the platelet count resulted in regression of the purpuric rash. CONCLUSION: To our knowledge, this is the first report of a facial thrombocytopenic purpura as the inaugural symptom of HSTL. It emphasizes the privileged position of the dermatologist for early recognition of potentially lethal HSTL.

Antigen presentation in the lung: dendritic cells and macrophages.

Antigen presentation is a required prime event before T-cell activation can occur. Cells which constitutively express major histocompatibility antigen class I or II are responsible for presenting antigens. These are essentially alveolar macrophages (AM) residing mostly in the air spaces, and dendritic cells (DC), which create a tight surveillance network just below the epithelial cells of the airways and in the loose connective tissue around the vessels or in the pleura. AM are poor antigen presenting cells compared to DC. AM when encountering foreign particles or organisms may, however, influence the degree of activity or maturation of neighbouring DC, by releasing cytokines. Thus, we will describe how the innate immune processes may influence specific immunity and perhaps Th1 and Th2 differentiation. Following the description of the differences in phenotype and functions of AM and DC, we will provide data showing that in some pathological conditions, such as sarcoidosis, AM can acquire some specificities of DC.

NLRC5, at the Heart of Antigen Presentation.

Nucleotide-binding domain and leucine-rich repeat containing receptors (NLRs) are intracellular proteins mainly involved in pathogen recognition, inflammatory responses, and cell death. Until recently, the function of the family member NLR caspase recruitment domain (CARD) containing 5 (NLRC5) has been a matter of debate. It is now clear that NLRC5 acts as a transcriptional regulator of the major-histocompatibility complex class I. In this review we detail the development of our understanding of NLRC5 function, discussing both the accepted and the controversial aspects of NLRC5 activity. We give insight into the molecular mechanisms, and the potential implications, of NLRC5 function in health and disease.
