Group A streptococcal fasciitis after submental tumescent liposuction.

Tumescent liposuction is a procedure with a good safety record. Local infection is rare but can result in devastating consequences. We report a rare case of group A streptococcal fasciitis complicating tumescent liposuction and highlight the importance of early diagnosis and treatment of this condition. A 62-year-old woman presented 8 days after submental liposuction and a platysmal plication procedure with signs and symptoms of cervical fasciitis. Microbiological analysis confirmed a group A streptococcal infection. By using early aggressive medical and surgical treatments, the disease was arrested before the onset of any necrotizing process. A high index of suspicion is required to make an early diagnosis of this potentially disfiguring and life-threatening infection.

Findings of the 1998 Infectious Diseases Society of America membership survey.

The Infectious Diseases Society of America (IDSA) conducted a survey in 1998 to characterize its membership and to determine their needs. The response rate was 39%. Although only 23% of the respondents spent most of their time in the field of teaching and research, 62% of the respondents listed an academic institution as their primary employer. According to survey results, 17% of respondents indicated that care of HIV-infected patients comprised one-half or more of their practices. Respondents noted shortcomings in their training as a result of recent changes in the clinical practice arena and the health care system; more than one-fourth of the respondents identified deficits in their preparation for administration, infection control, pharmacoeconomics, quality assurance, transplantation, and outcomes research. This survey discloses that the IDSA membership perceives a need for changes in IDSA-sponsored fellowship training programs and graduate educational activities.

Fellowship training in infectious diseases: a report from the regional and national meetings of infectious diseases division chiefs and program directors.

During the 2-year period April 1995 to April 1997, six regional meetings and one national meeting of division chiefs and program directors of adult infectious diseases programs in the United States were held to review fellowship training. Herein, we report data on job availability and job selection for recently graduated fellows. We summarize discussions on decreasing the number of fellows in training, and we outline suggested components of a core clinical curriculum and of three training tracks--clinician track, clinical investigator track, and basic investigator track.

Managed care and the infectious diseases specialist.

There is growing demand to contain health care costs and to reassess the value of medical services. The traditional hospital, academic, and research roles of the infectious disease (ID) specialist are threatened, yet there is an increasing need for expertise because of growing antimicrobial resistance and emerging pathogens. Opportunities exist to develop and expand services for the care of patients infected with human immunodeficiency virus and in infection control, epidemiology, outcomes research, outpatient intravenous therapy, and resource management. It is important for ID physicians to appreciate the principles involved in managed care and the areas in which ID services can be valuable. To be effective, physicians need to know about tools such as practice guidelines, physician profiling, outcomes monitoring, computerized information management, risk sharing, networking, and marketing, as well as related legal issues. With a positive attitude toward learning, application, and leadership, ID physicians can redefine their role and expand their services through managed care.

Prophylaxis against infection in total joint arthroplasty. One day of cefuroxime compared with three days of cefazolin.

The efficacy of cefuroxime was compared with the efficacy of cefazolin for prophylaxis against postoperative wound infection in a prospective, double-blind, multicenter study of 1354 patients who had had elective primary or revision total hip or knee arthroplasty. The patients were randomly assigned to receive either 1.5 grams of cefuroxime followed by 750 milligrams eight and sixteen hours later (for a total of one day of antibiotic treatment), or one gram of cefazolin every eight hours for nine doses (for a total of three days of antibiotic treatment). The first dose of each drug was administered fifteen to sixty minutes before the operative incision was made (for a primary operation) or after tissue samples had been obtained for culture (for a revision procedure). After the operation, the patients were assessed daily while hospitalized and then at two to three months and one year after the operation. Demographic characteristics and risk factors were similar in the two groups. For the patients who had had a primary hip arthroplasty, the rate of deep wound infection was 0.5 per cent (one of 187) for those who had received cefuroxime and 1.2 per cent (two of 168) for those who had received cefazolin. For the patients who had had a primary knee arthroplasty, the rate of deep wound infection was 0.6 per cent (one of 178) for those who had received cefuroxime and 1.4 per cent (three of 207) for those who had received cefazolin.(ABSTRACT TRUNCATED AT 250 WORDS)

PCP presenting as cavitary pneumonia: a case report.

As Pneumocystis carinii pneumonia cases increase, physicians must consider the various atypical radiographic presentations of the disease. The following case report illustrates one atypical presentation and the dramatic response to treatment.

gyrA mutations in ciprofloxacin-resistant, methicillin-resistant Staphylococcus aureus from Indiana, Minnesota, and Tennessee.

Mutational changes occurring at amino acid codons 84 and 85 located in the gyrA gene of methicillin-resistant Staphylococcus aureus (MRSA) were studied using radiolabeled oligonucleotide probes to examine the incidence of these ciprofloxacin resistance determinants in 30 MRSA isolates from Indiana, Minnesota, and Tennessee. Four separate oligonucleotide probes, one each corresponding to the wild-type sequence, a mutation at codon 84 (nucleotide 251), a mutation at codon 85 (nucleotide 253), and mutations at both, were used to examine the total genomic DNA from each of the 30 isolates, which had been restricted, electrophoresed, and Southern blotted. The probes indicated that 15 of the 28 ciprofloxacin-resistant isolates gave results consistent with a single mutation at codon 84. Four of the 28 ciprofloxacin-resistant strains had results consistent with a mutation at codon 84 and possibly at codon 85. The two ciprofloxacin-sensitive isolates from Tennessee showed homology with the wild-type probe sequence. Five isolates (4, Minnesota; 1, Tennessee) had no homology with any probe. By oligonucleotide probes, ciprofloxacin-resistant MRSA from diverse geographic regions contained similar gyrA mutations at codons 84 or 85 in 19 of 28 ciprofloxacin-resistant isolates.

Serum sickness-like illness associated with ciprofloxacin.

Serum sickness is a systemic hypersensitivity reaction initially reported in children receiving horse serum. Drugs such as penicillins, cephalosporins, and sulfonamides are now noted to be the most common etiologic agents of serum sickness-like reactions. This case report describes a serum sickness-like reaction temporally related to ciprofloxacin, a previously unreported adverse effect of this drug or any of the other quinolones.

Mycobacterium terrae osteomyelitis and septic arthritis in a normal host. A case report.

A 48-year-old previously healthy white man had progressive painful swelling of his proximal index finger and the proximal interphalangeal (PIP) joint. A biopsy revealed Mycobacterium terrae septic arthritis and osteomyelitis. Six months of therapy with isoniazid, rifampin, and ethambutol were not accompanied by any improvement and amputation was necessary.

Treatment of septic arthritis. Diagnostic approach and rational use of antibiotics.

The diagnosis of septic arthritis is best made by aspiration, either needle or arthroscopic, or by open drainage. Accurate clinical and microbiologic diagnoses are essential and dictate specific therapy. Although the exact length of intravenous antibiotic therapy is debatable, it is generally between two and six weeks, depending on the etiologic organism.

Randomized comparison of cefamandole, cefazolin, and cefuroxime prophylaxis in open-heart surgery.

A total of 337 patients undergoing coronary artery bypass grafting or cardiac valve replacement were randomly assigned to receive cefazolin (1 g every 8 h [q8h]), cefamandole (2 g q6h), or cefuroxime (1.5 g q12h) as an intravenous antibiotic prophylaxis. All drugs were administered within 60 min before the initial incision and were continued for 48 h postoperatively. No adverse effects related to the study drugs were observed. The percentage of patients with postoperative infection was 9% for the cefazolin group, 6% for the cefamandole group, and 5% for the cefuroxime group or 6.5% overall. There were more infection sites in patients treated with cefazolin than in those treated with cefuroxime (P = 0.05) or cefamandole (P = 0.06). Fewer wound infections occurred with cefuroxime (P less than 0.01) and cefamandole (P = 0.06) than with cefazolin. Analyses of the prophylactic regimens used in this study showed cefazolin and cefuroxime to be less costly than cefamandole.

Histoplasmosis in the acquired immune deficiency syndrome.

This report describes the experience with disseminated histoplasmosis in seven of 15 patients with the acquired immune deficiency syndrome (AIDS) diagnosed in Indianapolis since 1981. Three were homosexual, two were intravenous drug addicts, one was the spouse of another patient with AIDS and disseminated histoplasmosis, and the seventh was a hemophiliac. Six had associated infections: candidiasis in three, Pneumocystis carinii pneumonia, recurrent mucocutaneous herpes simplex infection, and disseminated Mycobacterium avium infection in two each, and disseminated infection with an unidentified mycobacterium in one. Clinical diseases suggested sepsis in four. Histoplasma fungemia occurred in five, but the diagnosis was established first by visualization of organisms in blood or bone marrow in three. Results of Histoplasma serologic tests were positive in each. Three died before receiving 50 mg of amphotericin B, three had prompt improvement with amphotericin B, and one was treated with ketoconazole to prevent dissemination. However, two of the three patients treated with amphotericin B had relapses after a 35 mg/kg course, and the third died within a month following therapy. Disseminated histoplasmosis is a major opportunistic infection in patients with AIDS from endemic areas. AIDS should be strongly considered in otherwise healthy persons with disseminated histoplasmosis, especially if risk factors for AIDS are present. Amphotericin B is not curative in these patients.

Rheumatologic manifestations of histoplasmosis in the recent Indianapolis epidemic.

Rheumatologic manifestations were noted in 24 (6.3%) of 381 patients with symptomatic histoplasmosis who were seen during a recent epidemic in Indianapolis. Typically, these patients had rapidly additive, rather than migratory, arthritis or arthralgia, which was symmetric in 50%. Ten patients had oligo- or monarticular disease. Knees, ankles, wrists, and small joints of the hand were the most common sites affected. Eleven patients had erythema nodosum. The rheumatologic manifestations were usually mild and, in all but 2 patients, resolved without treatment or with a brief course of nonsteroidal antiinflammatory drugs. The joint disease in patients with erythema nodosum was essentially the same as that seen in patients who did not develop skin lesions. However, those without erythema nodosum more frequently exhibited systemic features, e.g., chills, fever, anemia, and elevated erythrocyte sedimentation rates. Rheumatologic complaints led 16 of the patients in this series (67%) to seek medical attention, and in 3 patients they constituted the sole presenting complaint.

Clinical and laboratory features of disseminated histoplasmosis during two large urban outbreaks.

Clinical and laboratory features have been reviewed in 66 episodes of disseminated histoplasmosis that occurred during two large urban outbreaks in Indianapolis. Immunosuppression, age greater than 54 years, and presence of other serious underlying illnesses predisposed to the disseminated form of the disease; only 21% of patients lacked one of these risk factors. Central nervous system findings, splenomegaly, hepatomegaly, and lymphopenia suggested disseminated disease but were present in only about one-third of patients. Miliary or diffuse pulmonary infiltrates also suggested dissemination and were noted in about one-third of patients, while mediastinal lymphadenopathy was present in only 17%. Histoplasmal serologic tests, positive in 90% of patients, provided useful diagnostic clues. The diagnosis could be confirmed by culture in 88% of patients, and special stains were positive in about two-thirds. Although 10% of patients recovered without treatment, 11 patients (17%) died because of failure to suspect the diagnosis and initiate therapy promptly. Amphotericin B was effective in all patients receiving at least 500 mg, but relapse occurred if the total dose was less than 30 mg/kg. Ketoconazole appeared effective in non-immunosuppressed patients but not in those with underlying immunosuppression; however, a controlled trial comparing ketoconazole and amphotericin B is required to establish the role of this new fungistatic oral agent.
