Erythromelalgia is a clinical syndrome characterized by burning pain in the extremities together with erythema and increased skin temperature. Typically, the patients experience relief from cold, and aggravation from warmth. Symptoms are hypothesized to be caused by arteriovenous shunting and reduced nutritive skin capillary perfusion with corresponding tissue hypoxia. ⋯ We report erythromelalgia in a patient with acquired immune deficiency syndrome (AIDS). At peak pain intensity he actively cooled hands and feet for more than 12 h/day. Many doctors handling human immunodeficiency virus/AIDS patients are unfamiliar with erythromelalgia, and the condition can easily be overlooked, especially the more common milder cases.

The role of HLA antigens in the development of paracoccidioidomycosis.
Paracoccidioidomycosis is a systemic granulomatous disease that involves primarily the lungs and may disseminate to other organs and systems. It is caused by Paracoccidioides brasiliensis, a fungus that exhibits reversible thermal dimorphism and whose natural habitat is presently unknown. There are two main clinical forms: the acute (subacute) juvenile form and the chronic adult form. The former runs a more rapid course and is more severe than the latter. This mycosis is found throughout Latin America. Brazil accounts for 80% of reported cases. Presumably P. brasiliensis thrives in humid and hot places, especially near forests or farms. The infection is endemic in certain areas, especially in Brazil, Colombia and Venezuela, where nearly 100% of the population show cutaneous paracoccidioidina positive skin tests, indicating previous contact with the fungus, although a small percentage show clinical manifestations of the disease. ⋯ There is no evidence of association between a specific HLA antigen and paracoccidioidomycosis in the subjects studied. Further investigations are recommended.

Case ReportsLichen amyloidosis, ankylosing spondylitis and autoimmune thyroiditis: coincidence or association?
Primary localized cutaneous amyloidosis (PLCA) is characterized by the deposition of amyloid in a previously apparently normal skin with the absence of other systemic or cutaneous disorder. Although ankylosing spondylitis may be associated with secondary systemic amyloidosis, no reports have been found showing the association of this disease with PLCA. In addition, the association of PLCA with autoimmune thyroiditis has not been previously reported. We report a concomitant occurrence of lichen amyloidosis, ankylosing spondylitis and autoimmune thyroiditis in a caucasian woman.

Clinical TrialFactors influencing pain outcome in herpes zoster: an observational study with valaciclovir. Valaciclovir International Zoster Assessment Group (VIZA).
An observational study with valaciclovir was conducted to assess clinical outcome in herpes zoster, especially pain and associated neurological signs and symptoms in relation to a series of demographic and disease characteristics discernible at presentation. The safety and acceptability of valaciclovir for treatment of zoster was assessed in a wide variety of primary care and clinic referral settings. ⋯ This study confirmed the prognostic importance of advancing age and the intensity of prodromal or acute pain as risk factors for prolonged zoster-associated pain and persisting abnormal sensations in the affected dermatome. Ophthalmic zoster and pre-existing neurological disorders are also identified as highly significant risk factors for prolonged abnormal sensations in herpes zoster.
