Integrated Imaging Characterization of Adrenal Adenoma: False-Positive Metaiodobenzylguanidine (MIBG) Findings of Adrenal Scintigraphy.

BACKGROUND: Evaluation of a patient with melanoma in whom an adrenal mass was detected on CT and MR during follow-up and further characterized with PET-CT and MIBG scintigraphy. CASE REPORT: In this case report, we describe a patient with melanoma in whom an adrenal mass was detected on CT and MRI during post-surgical follow-up and was further characterized with radionuclide studies consisting of PET-CT and MIBG scintigraphy. Although the results of imaging studies suggested that the mass was a pheochromocytoma, a cortical adrenal adenoma was histologically proven. CONCLUSIONS: Integrated structural and functional imaging is recommended to characterize adrenal tumors; however, mistakes may occur and therefore careful imaging evaluation is required.

Mud-bath therapy and oral glucosamine sulfate in patients with knee osteoarthritis: a randomized, controlled, crossover study.

OBJECTIVES: To evaluate the efficacy and safety of combined treatment of mud-bath therapy and glucosamine crystalline sulfate (GlcN-S) in patients with knee osteoarthritis (OA). METHODS: This study was a randomised, controlled, crossover investigation. Patients were randomly assigned (1:1) by the investigators to two groups, named group 1 and 2. Group 1 included twenty-three patients receiving oral GlcN-S treatment from the beginning of the study (T0) to the end of the 3rd month of treatment (T3) and a combined treatment of both mud-bath therapy and GlcN-S from T3 to the end of the study at six months (T6). Group 2 included twenty-two patients receiving a combined treatment of both mud-bath therapy and GlcN-S from T0 to T3 and that discontinued mud-bath therapy, receiving GlcN-S treatment alone, from T3 to T6. Primary endpoints of the study consisted of evaluating OA severity and activity at baseline and at follow-up visits. RESULTS: All 45 patients, eligible for the study, completed the period of the crossover. In group 1, no significant difference was shown in the comparison from T0 to T3, while from T3 to T6 most variables were significantly improved. In group 2, instead, the comparison between T0 and T3 showed a significant difference in different parameters. When comparing T3 and T6, despite an improvement of all the variables, no significant difference was shown. CONCLUSIONS: The association of GlcN-S and mud-bath therapy has a positive and safe role in improving pain, function and quality of life in knee OA patients.

Crenotherapy modulates the expression of proinflammatory cytokines and immunoregulatory peptides in nasal secretions of children with chronic rhinosinusitis.

BACKGROUND: The effect of crenotherapy on major mucosal markers of inflammation, TNF alpha, human beta-defensins 2 (hBD-2), and calprotectin, are largely unexplored in pediatric chronic rhinosinusitis (CRS). The aim of this study was to investigate the effects of crenotherapy with sulfate-sodium-chloride water on mucosal markers of inflammation in children with CRS. METHODS: Children with CRS received 15-day crenotherapy consisting of sulfate-sodium-chloride thermal water inhalations by nasal aerosol (15 minutes/day). Concentrations of nasal mucosal markers of inflammation (TNF alpha, hBD-2, and calprotectin) were measured before and after crenotherapy. Presence of specific symptoms (nasal obstruction, nasal discharge, facial pain, sense of smell, and cough), value of symptoms score sino-nasal 5 (SN5), quality of life (QoL) score (1 [worse] to 10 [optimal]) were also assessed. RESULTS: After crenotherapy a significant reduction was observed in TNF alpha (from 0.14 ± 0.02 to 0.08 ± 0.01; p < 0.001), calprotectin (from 2.9 ± 1.0 to 1.9 ± 0.5; p < 9.001), and hBD-2 (from 2.0 ± 0.1 to 0.9 ± 0.6; p < 0.001) concentrations. A significant (p < 0.05) reduction in number of subjects presenting symptoms of nasal obstruction (100% versus 40%), nasal discharge (33% versus 13%), facial pain (30% versus 10%), and sense of smell (60% versus 20%) was observed. A significant improvement of SN5 (from 3.07 ± 0.76 to 2.08 ± 0.42; p < 0.001) was observed after the crenotherapy. QoL also improved after crenotherapy (from 4.2 ± 1.1 to 6.6 ± 1.0; p < 0.001). CONCLUSION: Crenotherapy induced a down-regulation of nasal mucosal inflammatory mediators in children with CRS.
