Colon perforation in a patient with hyperimmunoglobulin E (Job's) syndrome.

A Taiwanese boy was diagnosed as having hyperimmunoglobulin E syndrome at the age of 4 years. At age 18 he was admitted to the hospital because of pneumonia in the left lower lobe. Abdominal pain developed 9 days later, and his condition progressed to peritonitis. Colon perforation, 10 cm distal to the ileocecal valve, was found. Double-barrel ileostomy was performed, and reanastomosis was done 1 1/2 months later. Afterward, he was fine, and he had no significant gastrointestinal problems after being discharged. To the author's knowledge, this is the first reported case of hyperimmunoglobulin E syndrome complicated by colon perforation.

[Pain in the hip area accompanied by a fever].

In 3 patients, 2 women aged 16 and 64 years and 1 man aged 64 years, with pain in the left hip region and fever, the diagnosis psoas abscess was made. After antibiotic treatment and drainage they recovered well. The primary from of psoas abscess is presumably caused by haematogenous spread of bacteria, mostly Staphylococcus aureus. The secondary form is caused by spread of infection from surrounding tissue, mostly gastrointestinal micro-organisms with Crohn's disease and diverticulitis. Painful passive extension and endorotation as well as a painful flexion stress-test of the hip joint can indicate a psoas abscess. Echography and blood cultures should be performed if a psoas abscess is suspected. If echography is inconclusive, CT-scan can establish the diagnosis. The psoas abscess should be treated by percutaneous or surgical drainage combined with antibiotic therapy. The underlying cause of a secondary psoas abscess should be treated separately.

Unique epidemiology of nosocomial infection in a children's hospital.

A prospective study of the epidemiology of nosocomial infections was undertaken in a large pediatric hospital. Infections were identified during a 12-month period with the use of medical record audits, indices identifying high-risk patients, and analysis of positive cultures and rapid diagnostic tests for viruses, fungi, and bacteria. The attack rate of the entire hospital population surveyed was 4.1 nosocomial infections per 100 patients discharged. In contrast with studies of patients in general hospitals that included comparatively few children, the most common sites of nosocomial infections were the respiratory and gastrointestinal tracts. Staphylococcus aureus was the most commonly isolated pathogen. However, rotavirus was identified more frequently than Escherichia coli, and documented viral infections were more common than infections caused by gram-negative bacilli.

Postoperative wound infections: a study of bacteriology and pathogenesis.

Of 200 patients, 6.5% were skin carriers of Staphylococcus aureus and 3.5% became skin carriers after admission. Development of skin carrier state was associated with a long preoperative hospital stay. A second study of 275 cases showed that skin carriers of S. aureus had a significantly higher subsequent staph wound infection rate than non-carriers, but nose and/or throat carriers of S. aureus did not. Peroperative wound contamination was a significant factor in the subsequent development of wound infection. In clean surgery the infection rate was 5.9%. Both wound contamination and infection was due to gram positive organisms, usually S. aureus. When the gastrointestinal or biliary tract had been opened, the infection rate was 28%, the usual contaminating and infecting organisms were enteric and only occasionally S. aureus. There is a need for improved methods of minimizing peroperative wound contamination.

Oral streptogramins in the management of patients with methicillin-resistant Staphylococcus aureus (MRSA) infections.

OBJECTIVES: Chronic methicillin-resistant Staphylococcus aureus (MRSA) infections in debilitated patients are difficult to treat. We studied the clinical efficacy and safety of an oral streptogramin, pristinamycin, for these patients. PATIENTS AND METHODS: Patients were admitted consecutively to receive pristinamycin, usually with doxycycline, for 7-21 days. Fifty-six patients (average age 75 years) from hospital and community were treated for skin, soft tissue, chest and other infections. RESULTS: The overall clinical response rate was 39 of 53 patients (74%; 95% CI: 60%, 85%) cured or substantially improved, from 53 of 56 (95%) patients clinically and 49 of 56 (87.5%) patients bacteriologically evaluable. Toxic effects comprised gastrointestinal disturbances in eight patients (14%) and one (2%) possible skin rash. CONCLUSION: This study suggests that oral streptogramins may be useful in the management of debilitated patients with MRSA infections.

Missing anterior cervical plate and screws: a case report.

STUDY DESIGN: A case report of an anterior cervical plate and screws that disappeared completely. OBJECTIVES: To present a case of a missing anterior cervical plate and screws, this being quite a rare complication of a cervical implant. SUMMARY OF BACKGROUND DATA: No mention of this complication was found in the literature. METHODS: Methods in the literature and clinical presentation are reviewed. RESULTS: Dislodgment of an anterior cervical plate occurred in association with an methicillin-resistant Staphylococcus aureus infection. Three months later the implants had disappeared, presumably passing without notice through the gastrointestinal tract. Whole body fluoroscopy could not identify any residual plate or screws. No esophageal fistula could be detected by barium meal swallow study. CONCLUSIONS: The plate and screws became dislodged, eroded through the posterior wall of the esophagus, then traversed the limit of the gastrointestinal tract, passing with feces without significant morbidity. Whether the methicillin-resistant Staphylococcus aureus infection contributed to this unique circumstance or is coincidentally related to it remained a matter of speculation.

Comparison of staphylococcal and nonstaphylococcal endocarditis in narcotic addicts.

In a 54-month retrospective review, we compared the clinical features of 26 narcotic addicts with staphylococcal endocarditis (group 1) and ten other addicts with nonstaphylococcal endocarditis (group 2). The admission temperature and the respiratory rate of patients in group 1 were significantly higher (P less thn .05 and less than .02 respectively) than those of patients in group 2. Group 1 also differed from group 2 in the following variables: (1) bilateral multiple pulmonary infiltrates in 46% vs none in group 2; (2) greater incidence of symptoms referable to the central nervous system (50% vs none in group 2); and (3) gastrointestinal symptoms of vomiting, diarrhea, or constipation in 62% vs 10% in group 2. Serious cardiovascular, renal, and other complications were more frequent in staphylococcal endocarditis. Tricuspid regurgitation occurred with equal frequency in both groups and was of no value in differentiating staphylococcal from nonstaphylococcal endocarditis.

The tetracyclines.

The tetracyclines, among the first of the antibiotics to become available 50 years ago, remain widely used. Tetracyclines have bacteriostatic activity against a wide variety of pathogens that are responsible for many common and some exotic infections. They are particularly valuable in the treatment of atypical pneumonia syndromes, chlamydial genital infections, rickettsial infection (Rocky Mountain spotted fever, typhus, Q fever), Lyme disease, and ehrlichiosis. On the basis of pharmacokinetic considerations, doxycycline is the preferred agent among the tetracycline congeners. Minocycline may have a limited role in the treatment of methicillin-resistant staphylococcal disease in situations in which an oral antimicrobial agent may be appropriate. The tetracyclines are generally contraindicated during pregnancy and childhood because of their association with dental staining and interference with bone growth. Photosensitivity may occur with some tetracyclines, and several drug and food interactions may limit gastrointestinal absorption.

Pattern of bacterial infections in homozygous sickle cell disease. A report from Saudi Arabia.

Streptococcus pneumoniae is the leading pathogen in children with sickle cell disease. Forty children younger than 20 years of age who had sickle cell disease and septicemia, meningitis, or osteomyelitis/septic arthritis were identified. The causes included Streptococcus pneumoniae (20%) and gram-negative organisms (mainly Salmonella) (70%). The gram-negative infections occurred in the first decade of life in 45% of our patients. We believe that this pattern of infection is different and related to the mild nature of sickle cell disease in our patients and to their persistent splenic function. The administration of pneumococcal vaccination may also have played a role. Microinfarcts of the intestinal wall allow the access of gram-negative organisms to the circulation. In places where gastrointestinal tract infections, especially Salmonella, are common, antibiotic therapy effective against these organisms is recommended initially with adjustment after identification and sensitivities are known.

Loracarbef vs. cefaclor in pediatric skin and skin structure infections.

A double blind, randomized clinical trial involving 214 children, ages 6 months to 12 years, compared the safety and effectiveness of the new carbacephem loracarbef and the cephalosporin cefaclor for the treatment of skin and skin structure infections. The two agents were given primarily as oral suspensions. Dosages were 15 mg/kg/day in two divided doses for loracarbef and 20 mg/kg/day in three divided doses for cefaclor. Assessment 72 hours after completion of the 7-day course of treatment indicated a favorable clinical response plus eradication of the pretherapy pathogen in 97.3% of the 74 loracarbef-treated patients eligible for evaluation and 92.3% of 78 evaluable cefaclor-treated patients. Favorable response rates at a second posttreatment visit 10 to 14 days after the end of therapy were 95.6% in 68 evaluable loracarbef-treated patients and 86.2% in 65 treated with cefaclor. The incidence of adverse reactions, including gastrointestinal effects, was low in both groups. No statistical difference in clinical or bacteriologic efficacy or safety was detected between patients treated with loracarbef and cefaclor.

Pyodermatitis-pyostomatitis vegetans complicated by methicillin-resistant Staphylococcus aureus infection.

Pyodermatitis-pyostomatitis vegetans (PPV), a rare disorder of the skin and oral mucosa, is considered a highly specific marker for inflammatory bowel disease, especially ulcerative colitis (UC). Oral lesions (pyostomatitis vegetans) are seen without skin involvement but rarely without gastrointestinal symptoms. Bowel symptoms may be minimal and precede the onset of other lesions by months or years. Dermatologically, PPV is characterized by annular, pustular lesions, which may precede or appear at the same time as the oral lesions. We report a case of PPV and UC in which presentation was confused by acneiform lesions and methicillin-resistant Staphylococcus aureus colonization. Management was complicated because of the patient's job commitments and need to travel, and the involvement of a number of different specialties at different locations.

The importance of bacterial superantigens produced by Staphylococcus aureus in the treatment of atopic dermatitis using povidone-iodine.

Atopic dermatitis (AD) is frequently associated with intestinal and cervical lesions. Staphylococcus aureus produces many kinds of toxins, the bacterial superantigens. The detection rate of toxins was 80.1% from 196 S. aureus strains. Neurological examinations revealed abnormalities in 59 out of 81 AD patients. Cervical magnetic resonance imaging (MRI) was performed in 46 patients randomly and showed abnormal findings in 38 of these patients. In 23 patients who underwent MRI and duodenal biopsy, 3 were found to be normal neurologically and 2 patients showed normal duodenal tissue. However, 18 patients had abnormal findings both on neurological examination and in duodenal tissue. Serial duodenal biopsy tests were performed in 10 AD patients. In 5 patients, the findings of chronic duodenitis disappeared after the therapy with povidone-iodine. These data indicate that the therapy was effective not only for the skin lesions, but improved gastrointestinal tract lesions and cervical myelopathy, by eradicating bacterial superantigens.

Orally absorbable D-forphenicinol-cephalosporins.

The synthesis and biological evaluation of D-forphenicinol-cephalosporins are described. 7-Amino-3-(substituted)-3-cephem-4-carboxylic acid esters were coupled with N-tert-butoxy-carbonyl-D-forphenicinol derivatives. Most of cephalosporin analogs in this series had good antibacterial activities and were well absorbed from the gastrointestinal tract in mice. Among them, 7-(mono-O-methyl-D-forphenicinol)-3-propenyl analog showed the most significant result in biological evaluations.

[Clinical evaluation of cefpodoxime proxetil in the treatment of skin and soft tissue infections. A double blind comparison of cefpodoxime proxetil and cefaclor].

In order to objectively evaluate the effectiveness, safety and usefulness of the new oral cephem cefpodoxime proxetil (CS-807, CPDX-PR) for the treatment of skin and soft tissue infections, a double-blind comparative study was undertaken using cefaclor (CCL) as the control drug. CPDX-PR and CCL were administered for 7 days at daily doses of 400 mg (divided into 2 portions) and 750 mg (divided into 3 portions), respectively. A total of 243 patients (118 in the CPDX-PR group and 125 in the CCL group) was treated in this study. The effectiveness, safety and usefulness were evaluated in 222 (106 in the CPDX-PR group and 116 in the CCL group), 234 (113 in the CPDX-PR group and 121 in the CCL group) and in 223 patients (107 in the CPDX-PR group and 116 in the CCL group), respectively. There were no differences in patients' backgrounds between the 2 groups, except for the presence or the absence of surgical treatments. The results we obtained are summarized below: 1. In the evaluation of clinical efficacy by the subcommittee, excellent, good, fair and poor efficacy were observed in 36, 43, 17 and 10 patients in the CPDX-PR group, respectively; the efficacy rate was, therefore, calculated to be 74.5%. As for the CCL group, respective results were observed in 50, 39, 17 and 10 patients, indicating an efficacy rate of 76.7%. There was no significant difference between the 2 groups. Improvement rates judged by physicians in charge were 80.2% in the CPDX-PR group and 88.8% in the CCL group. Moreover, no significant difference in diseases or severity were found between the 2 groups. 2. As for the bacteriological efficacy, the 2 groups showed high elimination rates, as 90.1% and 91.6% of the disease causing bacteria were eliminated in the CPDX-PR group and in the CCL group, respectively. Elimination rates in single infections with Staphylococcus aureus were determined to be 85.7% in the CPDX-PR group and 85.0% in the CCL group. 3. Although 6 patients in the CPDX-PR group and 2 patients in the CCL group developed side effects, which were mainly gastrointestinal symptoms, there was no significant difference in the incidence of side effects between the 2 groups. Abnormal laboratory values were found in 5 patients in the CPDX-PR group and 1 patient in the CCL group. 4. There was no significant difference in the usefulness between the 2 groups.(ABSTRACT TRUNCATED AT 400 WORDS)

Low incidence of bacteremia following endoscopic retrograde cholangiopancreatography (ERCP).

Fifty patients (29 females) undergoing ERCP were studied prospectively for the occurrence of bacteremia associated with this endoscopic procedure. Each patient had blood samples drawn for aerobic and anaerobic cultures before endoscopy, after entering the duodenum, 5 and 15 minutes after cannulation of the papilla of Vater. Subcultures were made at 24 and 48 hours for a total of 1,200 cultures. No positive cultures were obtained in 48 patients. One patient developed a Staphylococcus epidermidis bacteremia during the procedure. The cleansing technic for the instruments consisted of alcohol and water only. Prophylactic antiobiotics were not administered. In contrast to other gastrointestinal procedures, our results suggest that bacteremia is an uncommon occurrence in ERCP despite the longer duration of the procedure and instrumentation of a sterile duct system.

Cefpodoxime proxetil in the treatment of skin and soft tissue infections.

Patients with skin and soft tissue infections were enrolled in a study comparing 2 dosage regimens of orally administered cefpodoxime proxetil; 204 patients with mild to moderate infections received cefpodoxime proxetil 200mg twice daily and 47 patients with severe infections received 400mg twice daily. Both dosage regimens were given for 7 to 14 days. 132 of 142 (93.0%) evaluable patients in the 200mg group and 22 of 29 (75.9%) in the 400mg group were clinically cured post-therapy, the remainder in both groups being classified as improved. The pathogen eradication rate at the end of therapy in the 200mg group was 161 of 165 (97.6%), and 38 of 38 (100%) in the 400mg group. Adverse reactions (drug-related) were reported by 20 (8.0%) patients overall, and there was no apparent relationship between the dosage group and the incidence of adverse reactions. The most commonly reported reactions involved the gastrointestinal tract (diarrhoea) or female genital tract (vaginitis). Cefpodoxime proxetil appears to be a useful and safe agent in the therapy of skin and soft tissue infections.

The efficacy and safety of linezolid as treatment for Staphylococcus aureus infections in compassionate use patients who are intolerant of, or who have failed to respond to, vancomycin.

OBJECTIVE: The incidence of infections caused by methicillin-resistant Staphylococcus aureus continues to increase annually. Unfortunately, only a few therapeutic agents are available for the treatment of patients with such infections and all of the existing drugs have limitations. A pressing need exists, therefore, to identify new antibiotics for use in this clinical setting. The efficacy and safety of linezolid were studied in a compassionate use treatment programme and the results of treating a subset of patients with S. aureus infections are presented here. METHODS: Patients received linezolid in a dosage of 600 mg intravenously (iv) and/or orally twice daily. Clinical and bacteriological responses were assessed after a minimum of 7 days and following completion of therapy. RESULTS: Seven hundred and ninety-six patients who suffered 828 episodes of infection were enrolled in the linezolid compassionate use protocol. Of these, 183 patients received linezolid for 191 infections caused by S. aureus; in 151 cases, patients were intolerant of vancomycin, had a mixed S. aureus/vancomycin-resistant enterococcal infection or had no iv access, and, in 40 cases, patients had failed to respond to treatment with vancomycin. The median age of the patients was 57 years (range 14-93 years) and 53.9% were female. The predominant sites of infection were as follows: bone or joint (27.2%); skin and skin structure (25.1%); bloodstream (20.9%); and lower respiratory tract (12.6%). The clinical success rates in the clinically evaluable and all-treated populations were 83.9% and 62.3%, respectively, whereas the bacteriological eradication rates were 76.9% and 70.2% in the bacteriologically evaluable and all-treated populations, respectively. Linezolid was well tolerated. In 76 (39.8%) of the 191 episodes of infection, patients experienced one or more adverse events or exhibited one or more abnormal laboratory results; in 35 (18.3%) of the 191 cases it was necessary to discontinue treatment. Gastrointestinal tract-related symptoms (nausea, vomiting and diarrhoea) were the most common possibly or probably related adverse events and the most common reasons for drug discontinuation. CONCLUSIONS: Linezolid was effective and well tolerated in patients with S. aureus infections who were enrolled in this compassionate use protocol.
