The Arizona group of gram-negative enteric microorganisms is closely related to the genus Salmonella. Arizona infection is common in avian and reptilian species. Whereas Arizona intestinal infection has been observed in humans, extraintestinal disease has infrequently been described. A case of a 23-year-old woman with systemic lupus erythematosus and sickle cell trait who acquired Arizona hinshawii osteomyelitis and septis arthritis is presented. The patient recovered after treatment with ampicillin and cephalosporins. Three previously described cases of bone and/or joint infection with Arizona are summarized. Because Arizona species frequently ferment lactose, it is possible that they are discarded from fecal isolates by bacteriology laboratories. It is conceivable that many intestinal and extraintestinal infections are either overlooked or mistakenly identified.

A patient with hypocomplementemic urticarial vasculitic syndrome (HUV) is presented. This is an immunological pathology, limited to skin or multisystemic, that requires a differential diagnosis with erythematosus systemic lupus on the same occasions. The ever-present symptom is skin participation, such as urticaria-angioedema or fixed exanthema; biopsy shows necrotizing venulitis with polymorphonuclear infiltration and leukocytoclastic powder. Typical laboratory data are: diminished C3, C4 and C1q; C1 inhibition can be low or normal; the more characteristic finding is the presence of C1q associated immunocomplexes. Leukocytoclastic necrotizing vasculitis was found in the skin biopsy. During the course of illness (three years) the patient presented moderate cutaneous symptoms and asthma, without other systemic participation. During this period, antihistamines and, occasionally, corticoids were administered with improvement. Moreover, the patient presented urticaria related to ampicillin ingestion, and furthermore, the presence of anaphylaxis to beta-lactam was diagnosed in vivo and specific IgE was found in the laboratory study. This feature was previously observed by other authors; however, we cannot determine why the IgE-mediated allergy to beta-lactam and a complement pathology like HUV are related.

To reassess the epidemiology and treatment of listeriosis in the United States, we reviewed greater than 120 cases of listeriosis from four medical centers in three geographically separated cities: Los Angeles County-University of Southern California Medical Center (LAC-USCMC); Rush-Presbyterian-St. Luke's Hospital, Chicago; the University of Illinois Hospital, Chicago; and Vanderbilt University Hospital, Nashville, Tennessee. The epidemiological pattern at LAC-USCMC was relatively narrow; more than two-thirds of the cases occurred during the perinatal period. Cases at Vanderbilt University Hospital represented the opposite end of the spectrum; the majority of these occurred in nonpregnant, older adults who had received organ transplants. An intermediate pattern of cases was observed at the two medical centers in Chicago. Potential risk factors included pregnancy, neonatal status, organ transplantation, renal failure, malignancy, systemic lupus erythematosus, steroid therapy, and AIDS (two cases). Antimicrobial agents noted to be effective were, as expected, penicillin and ampicillin; the cephalosporins were ineffective. The mortality associated with listeriosis occurred mainly among premature infants and stillbirths delivered from infected pregnant women and was markedly less among neonates and adults.

We report a case of peritonitis in a patient on continuous ambulatory peritoneal dialysis caused by Listeria monocytogenes. The patient was taking oral corticosteroids for underlying systemic lupus symptoms, and had classic signs and symptoms of peritonitis. There was initial clinical deterioration while in vitro data indicating that the organism was sensitive to vancomycin with a minimum inhibitory concentration of 0.5 micrograms/ml. The patient rapidly responded to intravenous ampicillin. We believe this to be the second reported case of L. monocytogenes peritonitis in a CAPD patient.

Drug-induced pleural side effects are rare and not usually identified. They may be a fibrous thickening of the pleura or an effusion, generally associated with an interstitial pneumopathy. Sometimes the pleural fluid is clear, sometimes hemorrhagic, and of varied cytological composition. The effusion can be uni- or bilateral. In the majority of cases, the pleural involvement stops when the causative agent is withdrawn. The pathology is usually attributed to a hypersensitivity mechanism when the following drugs have been given: nitrofurantoin, salazopyrine, erythromycin, ampicillin, gold salts, phenytoin, methysergide, ergotamine and bromocriptine. Some pleural lesions resemble lupus (induced by beta-blockers, hydralazine or procainamide). Amiodarone can cause fibroses or effusions via a toxic or hypersensitivity mechanism. In some instances, the mechanism remains unknown (1 case with imipramine, 1 case of fibrosis with perhexiline, 1 case of effusion with ibuprofen, 4 cases of effusion induced by dandrolene).

We have constructed a cDNA library for the trimethylguanosine-capped small RNAs (sRNAs) in the acellular slime mold Physarum polycephalum. Capped sRNAs were purified from total cellular RNA of vegetative microplasmodia by preparative immunoprecipitation with anti-trimethylguanosine antibody. The purified RNA was analyzed by polyacrylamide gel electrophoresis. Approx. eleven different capped sRNAs were observed with a size range of 70-204 nucleotides (nt). Based on their approximate sizes, the presence of trimethylguanosine cap, and the presence of a lupus type-Sm antigen, molecules U1-U7 (excluding U3) were identified. Further confirmation of the identity of molecule U1a was established by Northern hybridization, U4a by colony hybridization, and U6 and U7a by direct chemical sequence analysis. Purified capped sRNAs were tailed with oligo(A), and inserted into oligo(dT)-tailed plasmid pCDV1. The cDNAs were used to transform Escherichia coli strain HB101. Approx. 1.9 X 10(5) ampicillin-resistant (ApR) transformants were obtained per microgram of tailed sRNA. Dot-blot hybridization, using Physarum RNA precipitated with anti-cap antibody as a probe, indicated that approx. 94% of the ApR colonies contained recombinant DNAs. The library was screened by colony hybridization using heterologous sRNA probes. Clones hybridizing with heterologous sRNAs U1, U2, U4 and U7 were each represented in the library in approximately the same frequency as their relative abundance in the Physarum sRNA population they were derived from. The insert of one Physarum U4 clone was sequenced and was found to have 57.1% homology with nt 1-91 of the published sequence for rat U4 RNA. A 12-nt 'functional' subdomain of the rat U4 molecule was 83.3% conserved in Physarum U4.

The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

This paper describes a case of osteomyelitis due to Salmonella bovis morbificans in a patient with systemic lupus erythematosus (SLE) on long-term corticosteroid therapy. Although the organism was susceptible in vitro to chloramphenicol, ampicillin and co-trimoxazole, therapy with any of these drugs became impossible due to severe allergic reactions. A prolonged course of trimethoprim coupled with surgical debridement cured the lesion. The serum concentration of trimethoprim 24 hours after administration of a single oral dose of 300 mg was over four times the minimum inhibitory concentration (MIC) of the Salmonella sp. involved. These results indicate that trimethoprim may be effective in the treatment of Salmonella osteomyelitis.

Within a 6-year period from January 1991 to December 1996, 19 patients with Salmonella choleraesuis bacteremia were enrolled for clinical and microbiological analysis. Young children, the elderly and patients with hematological malignancy (36.8%), liver cirrhosis (26.3%), systemic lupus erythematosus (10.5%), chronic renal impairment (10.5%), and peptic ulcer (10.5%) were at high risk of this infection. The ratio of male to female was 3:1. Three cases (15.8%) were nosocomially acquired. Fever (89.5%), chills (57.9%) and anorexia (52.6%) were the most common clinical manifestations. Seven patients (36.8%) presented no gastrointestinal manifestations. Normal white blood cell count was noted in seven patients (36.8%), and neutropenia caused by underlying diseases or severe infection was found in six cases (31.6%). Various types of metastatic focal infections were found, such as septic arthritis, cutaneous infection, spontaneous bacterial peritonitis, and pneumonia. The severe immunocompromised status of patients and the high virulence of this pathogen may contribute to the high case fatality rate (21%). Higher resistance rate to commonly used antimicrobial agents was noted in ampicillin (94.7%), chloramphenicol (89.5%), and TMP/SMZ (63.8%). All strains of S. choleraesuis were susceptible to third-generation cephalosporins and fluoroquinolones. Generally, S. choleraesuis bacteremia should be taken into account in the differential diagnosis of sepsis in immunocompromised patients, even without gastrointestinal manifestations. The third-generation cephalosporins and fluoroquinolones may be the first choice for treatment of this invasive infections.

A case of beta-lactam antibiotic-induced pseudoporphyria is presented. A 24-year-old African American woman with systemic lupus erythematosus and end-stage renal disease on hemodialysis developed tense bullae on her forehead and cheeks after exposure to ampicillin-sulbactam and cefepime. Histologically, the lesions were similar to porphyria cutanea tarda, but without the associated porphyrin abnormalities. The lesions resolved spontaneously on cessation of the antibiotics.
