RESUMO
Paracoccidioidomycosis is a systemic fungal infection caused by Paracoccidioides brasiliensis and endemic in certain areas of Central and South America. We report a case of a 62-year-old-man with a complex history of tuberculosis and imaging findings of a cerebral lesion and bilateral adrenal enlargement. Biopsy of adrenal gland revealed Paracoccidioides brasiliensis. This case highlights the importance of travel history for diagnosis of paracoccidioidomycosis in non-endemic areas and emphasizes the clinical and histopathological similarities with tuberculosis.
RESUMO
BACKGROUND: Stress-relieving effects of balneotherapy compared to progressive muscle relaxation (PMR) and to resting were investigated by measuring subjective relaxation and salivary cortisol. It was also examined whether participants with a high versus low stress level would have a different relaxation response. METHODS: A sample of healthy volunteers was randomized to balneotherapy, PMR, or a resting control group, each intervention lasting for 25 min. Pre- and post-intervention salivary cortisol samples were collected, and participants rated their status of relaxation on a quantitative scale. In addition, 3 questionnaires were applied to detect participants' stress level and bodily complaints. RESULTS: 49 healthy participants were recruited (65.3% female). In a pre-post comparison, salivary cortisol decreased (F = 23.53, p < 0.001) and subjective relaxation ratings increased (F = 132.18, p < 0.001) in all 3 groups. Study participants in the balneotherapy group rated themselves as more relaxed after the intervention as compared to the other groups (F = 5.22, p < 0.009). Participants with a high versus low stress level differed in somatic symptoms and in morning cortisol levels, but showed a similar relaxation response. CONCLUSION: Findings suggest that compared to PMR and resting, balneotherapy seems to be more beneficial with regard to subjective relaxation effects and similarly beneficial with regard to a decrease in salivary cortisol.

Hypoxia-inducible factor 1 (HIF1) is a key regulator of angiogenesis and is involved in inflammation, which are two important features of the pathogenesis of peripheral artery disease (PAD). The gene for the HIF1-alpha subunit (HIF1A) carries two common mis-sense mutations, P582S (C>T, rs11549465) and A588T (G>A, rs11549467), which both have been related to increased trans-activation capacity of HIF1-alpha. The aim of the present study was to analyze the role of these polymorphisms in PAD. The study was designed as a case-control study including 917 patients with documented PAD and 969 control subjects. HIF1A genotypes were determined by exonuclease (TaqMan) assays. HIF1A P582S genotype frequencies were not significantly different between PAD patients (PP 82.2%; PS 16.5%; SS 1.3%) and control subjects (83.2%; 15.3%; 1.5%; p = 0.72). Similarly, HIF1A A588T genotype frequencies did not differ significantly between PAD patients (AA 95.9%; AT 4.1%) and control subjects (AA 96.8%; AT 3.2%; p = 0.28). In a multivariate logistic regression analysis including age, sex, smoking, diabetes, arterial hypertension and hypercholesterolemia, neither the HIF1A P582S polymorphism (odds ratio: 1.26; 95% confidence interval 0.92-1.74; p = 0.16) nor the A588T polymorphism (odds ratio: 1.17; 95% confidence interval 0.59-2.35; p = 0.66) was significantly associated with the presence of PAD. Both polymorphisms were furthermore not associated with age at onset of PAD, Fontaine stage of the disease or the ankle/brachial index of patients. We conclude that functional polymorphisms in the HIF1A gene do not contribute to susceptibility to PAD.
