Several differences were found in the profile of demographic parameters, diagnoses, medical visits, and rheumatologic procedures between patients seen at the University of Puerto Rico Medical Sciences Campus rheumatology practice and 3 community-based practices. Efforts may be required to diversify and increase the exposure of rheumatology fellows to patients with conditions commonly seen at the community setting.
We report a 55-year-old man with gouty arthritis who developed a 3-month history of low back pain, gradual lower extremities weakness and urinary incontinence. Lumbar MRI showed an exophytic lesion at L3-L4. Immediately after spinal decompression surgery, he developed fever, disorientation, polyarthritis, acute kidney injury and leucocytosis. He was treated with multiple antimicrobial agents for presumed spinal abscess but did not improve. Multiple body site cultures were negative. Aspiration of the sacroiliac joint revealed the presence of monosodium uric acid crystals. A diagnosis of acute gout was done, and he was treated with high-dose intravenous methylprednisolone and colchicine. Within 48 hours, he had a remarkable clinical improvement. At discharge, neurological and laboratory abnormalities had resolved. Awareness of risk factors for axial gout and a high degree of suspicion are important to establish a prompt diagnosis and treatment to prevent severe complications as seen in this case.
Biological life manifests in space through a large diversity of physical structures perfectly bind and identifiable in the environment. This reveals that all share a common generative design process which allows them the same physical identity in all the shapes that generates, The human ecological design process used in architecture is not able yet to reach this design identity neither the spontaneous integration associates to it. Why? Because the geometrical design process used in ecological architecture and living structures are not similar. Thus, this paper proposes, through the identification of some geometrical characteristics from the growth mechanism of living structures, a process of shape generation through shape grammar. With this generation process is possible to generate, only in geometrical terms, a large diversity of architectural models with a common identity, that reveals some geometrical characteristics of spatial integration that living structures share with the surround environment.
Polyarteritis nodosa (PAN) is a necrotising vasculitis that involves medium and small vessels. PAN generally presents with constitutional, cutaneous, neurological, renal and gastrointestinal manifestations. However, PAN initially involving a single organ/system is uncommon. Here, we present a 42-year-old man who was hospitalised because of severe right upper quadrant abdominal pain that started 2 months before. Physical examination was remarkable for right upper quadrant abdominal tenderness. Abdominopelvic CT showed lymphadenopathy but no hepatic, gallbladder, pancreatic, intestinal or renal abnormalities. Abdominal angiography showed multiple small aneurysms located in the jejunal and hepatic arteries characteristic of PAN. He had a prompt and remarkable response to high-dose corticosteroids and oral cyclophosphamide. Our case, together with other reports, suggests that PAN should be considered in patients presenting with right upper abdominal pain. Timely diagnosis and treatment reduce the overall morbidity and mortality of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
