Abstract
We describe the case of a patient with a two-year history of adult dermatomyositis (DM) who developed malabsorption revealing celiac disease. Our observation raises the question of an association between DM and celiac disease as part of a continuum, suggesting that celiac disease may be included within the spectrum of the gastrointestinal manifestations of DM and polymyositis (PM). From a practical point of view, our data indicate that the diagnosis of celiac disease should be suspected in PM/DM patients exhibiting malabsorption syndrome. Based on our findings, we further emphasize that an evaluation for celiac disease, including anti-gliadin antibodies, anti-endomysium antibody and tissue trans-glutaminase antibodies should be considered in PM/DM patients presenting with unusual and unexplained gastrointestinal features. This could lead to the early management of such patients, resulting in decreased morbidity (i.e., malnutrition and malignancy) related to misdiagnosed celiac disease.

Abstract
We present the results of the numerical simulation of the flow in the nasal cavity, going from the tip of the nostril to the nasopharyngeal region. The volume of the nasal cavity, obtained from axial and coronal scans, takes into account the geometries of the nasal valve and turbinates. The simulation is carried out with the FLUENT code which solves the equations of fluid mechanics. The obtained results for the inspiratory phase are analyzed from the velocities and pressures, paying special attention to the separation of the streamlines in the region located between the middle meatus and the olfactory area. The presented results show the potential of simulation when used in parallel with the clinical approach.

Abstract
We report the case of a patient with Whipple's disease (WD) who developed hypertrophic osteoarthropathy (HOA) characterized by digital clubbing, periostosis of the tubular bones, and polysynovitis. The HOA disclosed the recurrence of the patient's WD, since polymerase chain reaction (PCR) analysis clearly demonstrated the presence of Tropheryma whippelii in the synovial fluid from the patient's left knee. Initiation of appropriate antibiotic therapy resulted in complete healing of all clinical rheumatologic manifestations within 2 months and in disappearance of radiographic bone changes at 7-month followup. We suggest that HOA be included within the spectrum of rheumatologic manifestations of WD, and that an evaluation for WD should be considered in patients, especially middle-aged men, presenting with HOA even without gastrointestinal symptoms. PCR analysis may be useful in accurate diagnosis and management of early WD with unusual clinical manifestations, and may contribute to decreased morbidity and mortality.

Abstract
The aim of this study was to investigate the effect of the composition of diffusion-controlled release devices (type and amount of plasticizer, type of polymer) on the drug diffusivity and the resulting release kinetics in a quantitative way. Diltiazem hydrochloride and theophylline were investigated in ethyl cellulose (EC) and Eudragit((R)) RS 100, plasticized with various amounts of acetyltributyl citrate (ATBC), acetyltriethyl citrate (ATEC), dibutyl phthalate (DBP), dibutyl sebacate (DBS), diethyl phthalate (DEP), and tributyl citrate (TBC). Thin drug-containing films (monolithic solutions) were used to determine the diffusion coefficients experimentally. The effect of the type and amount of plasticizer on the drug diffusivity was found to be significant, whereas the chain length of the polymer only played a minor rule in the investigated systems. Interestingly, a quantitative relationship between the diffusion coefficient of the drug and the plasticizer level could be established. Based on these results, the release kinetics of diffusion-controlled drug delivery systems could be predicted. In this study, the release patterns from microparticles were calculated and the significant effect of the composition of the device on the resulting release rate was simulated. The latter could be effectively modified by varying the type and amount of plasticizer. Independent experiments verified the theoretical predictions. The practical benefit of the presented method is to calculate the required composition of diffusion-controlled drug delivery systems (monolithic solutions) to achieve desired release profiles.

Abstract
Lupus-like anticoagulant is commonly encountered in human immunodeficiency virus infection although thromboembolic manifestations are rare in HIV patients. We report the case of an HIV patient who developed gangrene of both forefeet associated with anticardiolipin antibodies. A 42-year-old woman had a 12-year history of HIV infection (stage B2). She presented with painful gangrene involving the forefeet of 4-day duration. Doppler ultrasonography, electromyography and nailfold capillaroscopy were normal. Skin biopsy revealed intracapillary thrombi and severe necrosis within the hypodermis; there was no evidence of vasculitis. Laboratory findings showed a marked inflammatory syndrome and the presence of anticardiolipin antibodies (IgG: 22 GPL U/ml). Several cutaneous manifestations are known to be associated with antiphospholipid syndrome, such as livedo reticularis, ulcers and gangrene of the extremities. Skin biopsy often shows noninflammatory thrombosis of small vessels within the dermis. Microcirculation damages have also been described in HIV infection, mainly vasculitis. In the present case report, the absence of both vasculitis and other causes suggest that anticardiolipin could be the culprit. But, it is possible that painful gangrene of the forefeet was secondary to HIV infection.
