Campylobacter cinaedi and C. fennelliae have been associated with proctocolitis, bacteremia, and asymptomatic rectal infection, primarily in homosexual men. To more directly assess the pathogenic role of these organisms, we studied their disease-producing potential in 12- to 25-day-old pig-tailed macaques (Macaca nemestrina). Four infant monkeys were challenged with 10(8) to 10(9) C. cinaedi, three were challenged with C. fennelliae, two were challenged with C. jejuni, and one received no microorganisms. Watery or loose stools without associated fever or fecal leukocytes developed 3 to 7 days postinoculation in all of the animals given C. cinaedi, C. fennelliae, and C. jejuni, but not in the control animal. Stool cultures were simultaneously positive and remained so in the animals challenged with C. cinaedi or C. fennelliae for 3 weeks after inoculation despite the resolution of clinical illness. All of the animals challenged with C. cinaedi and C. fennelliae became bacteremic, and three had clinical evidence of septicemia. Histopathologic evaluation of rectal biopsies (five animals) and necropsy (one animal) showed no evidence of mucosal disruption. Specific immunoglobulin M and immunoglobulin G antibody responses occurred in all of the animals challenged with C. cinaedi and C. fennelliae, as determined by enzyme-linked immunosorbent assay and immunoblotting. We conclude that C. cinaedi and C. fennelliae consistently produce a diarrheal illness accompanied by bacteremia and followed by prolonged gastrointestinal colonization in M. nemestrina.

Helicobacter cinaedi has been most frequently isolated from rectal swabs of homosexual men with proctocolitis. The microorganism is a normal intestinal inhabitant of hamsters. We report a case of septicemia and meningitis by H. cinaedi in a neonate whose mother cared for pet hamsters during the first two trimesters of her pregnancy. The isolate was detected after 3 days of incubation in a Bact/Alert pediatric blood culture vial and an enrichment broth culture of the cerebrospinal fluid. H. cinaedi should be added to the list of unusual fastidious organisms that cause sepsis and meningitis in the newborn.

Pericardial abscess is a very rare complication of sepsis. Authors describe the case of a 69-year-old woman. In her case staphylococcus sepsis led to pericardial abscess. During the course positive blood cultures (3x) indicated the sepsis and pus was obtained from the left pleural cavity (pleuropneumonia). Concomitant purulent process in the left shoulder also was noted. Decline immunity due to long-standing corticoid therapy (prednisone) for proctocolitis idiopathica was observed. Following antibiotic treatment successful surgical evacuation of the pericardial abscess was performed.

Patients infected with the human immunodeficiency virus, particularly male homosexuals, are prone to develop disorders involving the anorectal and perineal structures. Cross-sectional imaging techniques, such as multidetector computed tomography with multiplanar reformations and magnetic resonance imaging performed with phased-array coils, are increasingly adopted to detect and stage infectious and neoplastic diseases, and to assess posttreatment modifications. Pyogenic perianal sepsis may be usefully investigated with imaging, particularly to assess the presence and topography of abscess collections to allow a correct surgical choice. Rectal inflammatory involvement is frequently detected during intestinal opportunistic infections, such as cytomegalovirus, pseudomembranous, and amebic colitides, including primary and secondary imaging signs consistent with proctocolitis. Anal carcinoma and intestinal lymphoma are increasingly diagnosed; therefore, special attention should be paid to the identification of solid tissue consistent with tumor; furthermore, MRI provides optimal staging and posttreatment follow-up of neoplastic lesions. Knowledge of this varied spectrum of anorectal and perineal opportunistic abnormalities and their imaging appearances should help radiologists to propose appropriate differential diagnoses, suggest correlation with laboratory and microbiological assays or biopsy, and reliably assess therapeutic response.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity that manifests as profuse, repetitive vomiting, often with diarrhea, leading to acute dehydration and lethargy or weight loss and failure to thrive if chronic. FPIES is elicited most commonly by milk and soy proteins; however, rice, oat, and other solid foods may also elicit FPIES. Certain FPIES features overlap with food protein-induced enteropathy and proctocolitis, whereas others overlap with anaphylaxis. FPIES is not well recognized among pediatricians and emergency department physicians; the affected children are often mismanaged as having acute viral gastrointestinal illness, sepsis, or surgical disease, delaying diagnosis of FPIES for many months. The aim of this review is to provide case-driven presentation of the features of FPIES. Although randomized clinical trials on management options are missing, the relevant current literature and authors' experience are reviewed in detail.

Non-IgE-mediated food allergic disorders account for up to 40% of milk protein allergy in infants and young children. We aim to review the recent literature and to provide an update on diagnosis and management of food protein-induced enterocolitis syndrome (FPIES) and food protein-induced allergic proctocolitis (FPIAP). The peer-reviewed articles indexed in PubMed have been reviewed. FPIES manifests in infants as profuse, repetitive vomiting and lethargy, often with diarrhea, leading to acute dehydration, or weight loss and failure to thrive, in chronic form. FPIES is caused most commonly by cow's milk (CM) and soy proteins; rice, oat, and other solid foods may also trigger FPIES. FPIES rarely occurs in the exclusively breastfed infants. FPIES is underrecognized; children are often mismanaged as having acute viral gastrointestinal illness, sepsis, or surgical disease, delaying diagnosis of FPIES for many months. Approximately 25% of children with FPIES develop food-specific IgE antibodies and some transition to immediate food allergy; IgE positivity is associated with a more protracted course. FPIES is a self-limiting condition, with most cases resolving by age three to five years. Ondansetron may be helpful in managing acute FPIES. FPIAP is a benign condition of bloody stools in a well-appearing infant, with usual onset between one and four weeks of age. Up to 60% of cases occur in exclusively breastfed infants and resolve with maternal elimination of CM and soy proteins. The majority of cases resolve by age 12 months. FPIES may transition to IgE-mediated food allergy in some patients; IgE positivity to the FPIES food is a marker of a more persistent disease. FPIAP is benign and resolves by age 12 months in most patients.
