Eleven patients with rheumatoid arthritis that had been refractory to conventional drug therapy were treated with total lymphoid irradiation (TLI). Followup continued for 6 months in 9 patients, 12 months in 6 patients, and 24 months in 3 patients. At 6 and 12 months post-TLI, a significant improvement in clinical disease activity was demonstrated. Side effects noted during TLI included fatigue, nausea, diarrhea, and vomiting. One patient died of cardiorespiratory arrest, 2 patients died of kidney failure secondary to generalized amyloidosis, and 1 patient died of septic shock secondary to a multilocular septic arthritis. One patient experienced 2 episodes of septic arthritis; 2 patients manifested delayed wound healing. Immunologic assessments showed consistent lymphopenia in all patients. T lymphocyte subsets decreased after TLI, and showed a transient increase at 6 months post-TLI. The suppressed mitogen responsiveness, which was noted 2 months after irradiation, was found to increase almost to the pre-TLI levels at 12 months. The observed increase in morbidity and mortality after TLI is evidence that discourages the use of this therapeutic technique, at least in its present form.

Thirty-four patients were treated with intravenous ciprofloxacin. Thirty infections occurring in 28 patients were assessable for the efficacy analysis. The drug dosage was 300 mg every 12 hours in 19 patients and 200 mg intravenously every 12 hours in nine patients. Twelve patients were also given ciprofloxacin orally after initial intravenous therapy. The mean duration of total therapy was 31 days. The overall clinical response rate was 87 percent, and the bacteriologic response rate was 70 percent. Favorable responses were observed in 10 of 12 patients with osteomyelitis/septic arthritis; seven of eight with soft tissue infection; four of four with pneumonitis; one of two with cystic fibrosis; and four of four with urinary tract infections. Resistance to ciprofloxacin developed in three Pseudomonas aeruginosa isolates. Toxicity was minor: phlebitis occurred in six patients, nausea in six, and rash in one. Intravenously administered ciprofloxacin or intravenous ciprofloxacin followed by oral ciprofloxacin is a safe and effective therapy for serious infections.

Cefepime, a novel, injectable alpha-methoxyimino aminothiazolyl cephalosporin, is active in vitro against many of the Gram-positive and Gram-negative bacteria which cause severe infections, including Pseudomonas aeruginosa. It is more active than existing third-generation cephalosporins against multiply-resistant strains of Enterobacteriaceae because of its low affinity for beta-lactamases and its resistance to hydrolysis by these enzymes. Cefepime retains its high potency of activity against methicillin-susceptible Staphylococcus aureus, coagulase-negative staphylococci and streptococci other than enterococci. Seventy-four patients (46 male and 28 female) were treated with cefepime 2 g i.v. every 12 h; 61 patients were evaluable for efficacy (39 male and 22 female). The infections included pneumonia caused by Gram-negative bacilli (21 patients, six with bacteraemia), septicaemia (seven), pyelonephritis (two), osteomyelitis (23, mainly caused by S. aureus), septic arthritis (four) and soft tissue infections (four, one with bacteraemia). Responses were as follows: 52 (85.3%) patients cured; three (4.9%) improved and six (9.8%) failed. The failures included three patients with osteomyelitis, one with pyelonephritis and two with pneumonia. The pathogens and eradication rates were: S. aureus 23/24 (96%), Staphylococcus epidermidis 4/4, Streptococcus spp. 10/10 (100%), P. aeruginosa 11/14 (79%), Enterobacteriaceae 28/28 (100%), Haemophilus spp. 3/3 and others 7/7. Clinical adverse effects included diarrhoea in 11 patients (14.9%) nausea in five (6.8%) and pruritus in three (4.1%). Laboratory abnormalities included leucopenia in three patients (4.1%) and direct Coombs' conversion in 32 (43.2%). Patients were treated for an average of 31.8 days for osteomyelitis and 11.9 days for other infections.(ABSTRACT TRUNCATED AT 250 WORDS)

Septic arthritis of the temporomandibular joint (TMJ) has a high morbidity, is infrequently reported, and has been described almost exclusively in adults. We present two cases of septic arthritis of the TMJ that occurred in children after minor blunt trauma. Literature related to septic arthritis of the TMJ was reviewed, and a composite list of cases was constructed. The most common causes were various infections of the head and neck, rheumatic joint disease, and iatrogenesis. Pathogens may gain access to the TMJ by several routes. Patients typically present with an acute, tender, monarticular arthritis with associated swelling and erythema. Malaise, nausea, and vomiting may also be present. Traumatic effusions, fractures, and neoplasms may present in a similar fashion, and mimic TMJ septic arthritis. Staphylococcus aureus is the most commonly reported pathogen and often causes permanent joint damage. Aspiration and analysis of joint fluid, as well as blood chemistry, imaging studies, and clinical impression, may assist in the diagnosis. Timely diagnosis and treatment are essential for a successful outcome; therapy should include antimicrobial agents, adequate drainage, and resting of the joint. Complications include spread of infection, postinfectious bony changes, and fibrous (or bony) ankylosis of the temporomandibular joint.

Bone and joint infections have traditionally required long-term parenteral antimicrobial therapy, which is often expensive and inconvenient. Because of their excellent absorption and tissue penetration, oral quinolones may provide an alternative to parenteral therapy. This multicenter study was designed to evaluate the efficacy and safety of oral fleroxacin in osteomyelitis and septic arthritis. A total of 96 patients with either septic arthritis or acute or chronic osteomyelitis from 17 U.S. centers were enrolled in a noncomparative study using oral fleroxacin 400 mg per day. Patients with implantable devices were excluded. Proof of infection for evaluability required clinical findings in addition to bacteriologic recovery of a susceptible organism from synovial fluid or bone. Treatment lasted 2-12 weeks. Clinical and bacteriologic outcomes were judged at the conclusion of therapy and in the 6-week follow-up period. A total of 30 patients qualified for efficacy analysis (26 osteomyelitis, 4 septic arthritis). Bacteriologic cure was achieved in 77% of the osteomyelitis group and 50% of the septic arthritis group. Clinical cures were reported in 54% of the osteomyelitis group and 50% of the septic arthritis group. Staphylococcus aureus was the most frequently recovered pathogen (62% evaluable cases). Safety was evaluated in 96 patients. The most common side effects were nausea, vomiting, and skin reactions. Oral fleroxacin may be a safe, effective, and certainly less expensive alternative to standard intravenous antimicrobial therapy in patients with bone and joint infections.

The object of this open-label, noncomparative, multicenter study was to evaluate the efficacy and safety of 400 mg of fleroxacin administered orally once daily for 2-12 weeks to patients with bone and joint infections (osteomyelitis, septic arthritis, and prosthetic joint infection). A total of 90 adult patients (56 men and 34 women) were treated at 11 centers. Patients returned on days 5-9 of treatment, subsequently every 2 weeks during treatment, and 0-3 days and 28-42 days (compulsory follow-up) after treatment for assessment of bacteriologic, clinical, and safety parameters. A total of 19 patients (13 with osteomyelitis, 5 with septic arthritis, and 1 with prosthetic joint infection) were bacteriologically evaluable. Staphylococcus aureus was the predominant pathogen isolated in all evaluable infections. Of the 13 patients with osteomyelitis, 11 (85%) were bacteriologically cured and 10 (77%) were clinically cured. Three of the five patients with septic arthritis and the single patient with a prosthetic joint infection were both bacteriologically and clinically cured. Clinical adverse events related to fleroxacin were reported by 25 (28%) of the 90 patients. Most of these events involved the digestive system (primarily constipation and nausea) and the central nervous system (primarily insomnia and headache). The majority of these were of mild or moderate intensity and occurred during the first 2 weeks of treatment. Adverse events led to premature discontinuation of treatment in seven patients. Bone and joint infections continue to represent a therapeutic challenge. Treatment is based mainly on surgical procedures (drainage, sequestrectomy, ablation of implants, and implantation of cement impregnated with antibiotics) and on parenteral administration of antibiotics, requiring hospitalization of the patient. Fleroxacin, a new fluoroquinolone, has proven in vitro activity against bacteria involved in bone and joint infections. Its oral, once-daily administration, which eliminates hospitalization and its attendant costs, makes this drug an effective outpatient treatment of bone and joint infections.

Lemierre syndrome (postanginal septicemia) is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. A high degree of clinical suspicion is necessary for diagnosis. Fusobacterium necrophorum is the usual etiologic agent. The disease progresses in several steps. The first stage is the primary infection, which is usually a pharyngitis (87.1% of cases). This is followed by local invasion of the lateral pharyngeal space and IJV septic thrombophlebitis (documented in 71.5% of cases), and finally, the occurrence of metastatic complications (present in 90% of cases at the time of diagnosis). A sore throat is the most common symptom during the primary infection (82.5% of cases). During invasion of the lateral pharyngeal space and IJV septic thrombophlebitis, a swollen and/or tender neck is the most common finding (52.2% of patients) and should be considered a red flag in patients with current or recent pharyngitis. The most common site of metastatic infection is the lungs (79.8% of cases). In contrast to the preantibiotic era, cavitating pneumonia and septic arthritis are now uncommon. Most patients (82.5%) had fever at some stage during the course of the disease. Gastrointestinal complaints such as abdominal pain, nausea, and vomiting were common (49.5% of cases). An elevated white blood cell count occurred in 75.2% of cases. Hyperbilirubinemia with slight elevation of liver enzyme levels occurred in one-third of patients, but frank jaundice was uncommon, in contrast to its high frequency reported in the preantibiotic era. We conclude that, most likely as a consequence of widespread antibiotic use for pharyngeal infections, the typical course of the disease has changed since Lemierre's original description. The typical triad in our series was: pharyngitis, a tender/swollen neck, and noncavitating pulmonary infiltrates. The previous classical description of severe sepsis with cavitating pneumonia and septic arthritis was not commonly seen in our review. Mortality was low in our series (6.4%), but significant morbidity occurred, which was likely preventable by early diagnosis and treatment. The pathophysiology, natural history, diagnostic methods for internal jugular vein thrombosis, and management are discussed.

This retrospective study was conducted in order to determine the clinical and microbiologic features of infection with Salmonella enterica serotype Choleraesuis. Between March 1999 and December 2002, 55 patients with 66 isolates were enrolled for analysis. The ratio of males to females was 2.2:1. Most patients were older than 60 years (56%) and had underlying diseases (78%), such as diabetes mellitus, malignancy, and peptic ulcer. Fever (85%) was the most common clinical manifestation, followed by abdominal pain/fullness (31%). The gastrointestinal manifestations, including nausea/vomiting or diarrhea, accounted for only 13% and 11% of patients, respectively. S. enterica serotype Choleraesuis was extremely invasive, with a high predilection to cause bacteremia (78% of the isolates were from blood). Various types of metastatic focal infections were found, including infected arterial aneurysm, osteomyelitis, septic arthritis, urinary tract infection and wound infection. The crude mortality rate was 18% (10 deaths in 55 cases). Nearly all isolates were susceptible to the third-generation cephalosporins. A higher resistance rate to commonly used antimicrobial agents was found with ampicillin (85%, 56/66), trimethoprim-sulfamethoxazole (81%, 40/49), chloramphenicol (96%, 47/49), and ciprofloxacin (49%, 30/61). In view of the emergence of fluoroquinolone resistance, the third-generation cephalosporins appear to be the best choice for treatment of invasive infections caused by this organism.

Fusobacterium necrophorum infections are rare. We report a 15-year-old male who presented with tachycardia, nausea, vomiting, diarrhoea and ankle pain. He rapidly deteriorated requiring ventilation and vasopressors. Imaging of his thorax showed airspace consolidation, pulmonary cavitations and empyema. The ankle required drainage of purulent material. A thrombus in his internal jugular vein (Lemierre's syndrome) and an abscess in his obturator internus were subsequently found. Fusobacterium necrophorum was identified in blood culture on day nine. The patient recovered with antibiotics and surgical interventions for empyema and septic arthritis. Fusobacterium necrophorum should be a suspected pathogen in septic shock complicated by metastatic abscess formation.

A 40-year-old female patient presented with persistent severe back pain radiating to the right leg, abdominal pain and constipation. Other clinical symptoms included nausea, vomiting and high-grade fever. Clinical examination showed generalised abdominal and lower back tenderness. There was no sensory loss or motor weakness in lower limbs, however investigations showed raised inflammatory markers. Radiographs of the lumbar spine and hip joint were normal. MRI revealed a septic arthritis of the right L3/4 facet joint, associated with a large abscess extending anteriorly to the right paraspinal muscles and posteriorly into the right posterolateral aspect of the epidural space in the central spinal canal, with moderate compression of the dural sac. Unlike any other reported similar case, this septic arthritis developed without prior medical intervention. The patient was treated successfully with ultrasound guided drainage of the facet joint/abscess and antibiotics.
