ED is more frequent in patients with dcSSc than in those with lcSSc, and is more likely to deteriorate over time. Given the potential associated risks of erosive esophagitis, Barrett's esophagus, and esophageal cancer in patients with SSc, routine screening and monitoring for ED is advised.
Wegener's granulomatosis (WG) is a multisystem granulomatous, necrotizing vasculitis of presumed autoimmune origin that affects small- to medium-sized blood vessels. The respiratory tract and kidneys are typically involved (Gross and Reinhold-Keller, "Clinical features of primary ANCA-associated vasculitis" in Oxford textbook of rheumatology, third edition, 2004). The limited form usually involves the head and neck, lacks renal involvement, and may not progress to generalized disease (Cassan et al., Am. J. Med. 49:366-379, 1970). Ocular involvement, which may be the initial manifestation, is often encountered and can result in significant morbidity and possibly blindness (Pakrou et al., Semin. Arthritis Rheum. 35:284-292, 2006). We report an unusual case of WG presenting as an orbital mass. The diagnostic triad of granulomatous inflammation with multinucleated giant cells, vasculitis, and necrosis was discovered on histopathology (McDonald and Edwards, JAMA 173:1205-1209, 1960).
The gastrointestinal tract is commonly involved in patients with systemic sclerosis (SSc) (Am J Gastroenterol. 1972;58:30-44). Intestinal manifestations of SSc include impaired motility, malabsorption, bacterial overgrowth, jejunal and wide-mouthed colonic diverticuli, localized dilatation, pseudo-obstruction, and, less commonly, pneumatosis cystoides intestinalis (PCI) (Rheumatology. 2009;48:iii36-iii39; J Clin Gastroenterol. 2008;42:5-12). Benign spontaneous pneumoperitoneum is a rare complication of SSc and is often associated with PCI (Mo Med. 1967;64:117-118). We report a case of spontaneous pneumoperitoneum without evidence of peritoneal irritation in a malnourished patient with long-standing SSc. Computed tomography scan of the abdomen and pelvis on admission revealed pneumoperitoneum with PCI without visceral perforation. Subsequent imaging revealed the persistence of the pneumoperitoneum with resolution of the PCI. It is important for the clinician to recognize benign spontaneous pneumoperitoneum as a possible complication in patients with SSc and to be able to differentiate this from a ruptured viscus with peritonitis based on clinical presentation. The management of benign spontaneous pneumoperitoneum is supportive, thereby avoiding unnecessary surgery.
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.
