TrueNTH sexual recovery study protocol: a multi-institutional collaborative approach to developing and testing a web-based intervention for couples coping with the side-effects of prostate cancer treatment in a randomized controlled trial.

BACKGROUND: Over half of men who receive treatment for prostate suffer from a range of sexual problems that affect negatively their sexual health, sexual intimacy with their partners and their quality of life. In clinical practice, however, care for the sexual side effects of treatment is often suboptimal or unavailable. The goal of the current study is to test a web-based intervention to support the recovery of sexual intimacy of prostate cancer survivors and their partners after treatment. METHODS: The study team developed an interactive, web-based intervention, tailored to type of treatment received, relationship status (partnered/non-partnered) and sexual orientation. It consists of 10 modules, six follow the trajectory of the illness and four are theme based. They address sexual side effects, rehabilitation, psychological impacts and coaching for self-efficacy. Each includes a video to engage participants, psychoeducation and activities completed by participants on the web. Tailored strategies for identified concerns are sent by email after each module. Six of these modules will be tested in a randomized controlled trial and compared to usual care. Men with localized prostate cancer with partners will be recruited from five academic medical centers. These couples (N = 140) will be assessed prior to treatment, then 3 months and 6 months after treatment. The primary outcome will be the survivors' and partners' Global Satisfaction with Sex Life, assessed by a Patient Reported Outcome Measure Information Systems (PROMIS) measure. Secondary outcomes will include interest in sex, sexual activity, use of sexual aids, dyadic coping, knowledge about sexual recovery, grief about the loss of sexual function, and quality of life. The impact of the intervention on the couple will be assessed using the Actor-Partner Interaction Model, a mixed-effects linear regression model able to estimate both the association of partner characteristics with partner and patient outcomes and the association of patient characteristics with both outcomes. DISCUSSION: The web-based tool represents a novel approach to addressing the sexual health needs of prostate cancer survivors and their partners that-if found efficacious-will improve access to much needed specialty care in prostate cancer survivorship.

Combination vaccines: practical considerations for public health and private practice.

BACKGROUND: Although the current immunization schedule for children requires as many as four or five injections at a single visit, both parents and health care providers hesitate to administer more than two or three simultaneous injections. Therefore new combination vaccines that include multiple unrelated antigens are needed. METHODS: Individuals from the Immunization Division of the Colorado State Department of Health and pediatricians in private practice in Denver, CO, were interviewed and asked about incorporating new combination vaccines into their practice. RESULTS: At a state health department level the transition to combination vaccines will likely require reprioritizing of public health resources. In addition state health officials are important information resources for public and private providers, as well as for the community. At the level of the private provider combination vaccines hold promise for simplifying the immunization schedule, but successful implementation will require education and guidance on how best to integrate the new combination into practice. CONCLUSIONS: Combination vaccines are the immediate solution to the addition of new childhood vaccines and will alleviate the concern of parents and physicians regarding the trauma related to multiple injections at a single visit.

Erythrocyte sedimentation rate and C-reactive protein discrepancy and high prevalence of coronary artery abnormalities in Kawasaki disease.

BACKGROUND: An outbreak of Kawasaki disease (KD) in Colorado between November, 1997, and June, 1998, provided the opportunity to study inflammatory indices and coronary artery abnormalities. METHODS: Medical records of the 33 patients diagnosed with KD at The Children's Hospital during the outbreak were reviewed. Demographic and clinical information, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and echocardiogram results were recorded. Traditional abnormalities (dilatation, aneurysm, ectasia), as well as "prominence" of the coronary arteries were noted. RESULTS: Twenty-five patients had CRP and ESR performed on the day of admission; 11 of 25 (44%) had a discrepancy between the height of the ESR and CRP values (high ESR and low CRP or low ESR and high CRP). The mean CRP was higher in patients who presented in <10 days than in patients who presented in > or =10 days: 13.9 mg/dl vs. 5.2 mg/dl (P = 0.01). The ESR value did not correlate with the day of illness. Age, gender or presence of coronary artery abnormalities did not correlate with the height of CRP or ESR elevation. Thirty percent of patients had at least one abnormality on their initial echocardiogram (dilatation, aneurysm, ectasia). An additional 24% of patients displayed prominence as the only finding on their initial echocardiogram. Of the 33 patients 7 (21.2%) had coronary artery aneurysms. CONCLUSIONS: Many patients with KD have discrepancies in the degree of elevation of CRP and ESR. Physicians should consider obtaining both tests in patients with KD. This outbreak was associated with a high degree of coronary artery abnormalities. The finding of coronary artery prominence is an observation that deserves further study.

Pivotal phase III trial of two dose levels of denileukin diftitox for the treatment of cutaneous T-cell lymphoma.

PURPOSE: The objective of this phase III study was to determine the efficacy, safety, and pharmacokinetics of denileukin diftitox (DAB389IL-2, Ontak [Ligand Pharmaceuticals Inc, San Diego, CA]) in patients with stage Ib to IVa cutaneous T-cell lymphoma (CTCL) who have previously received other therapeutic interventions. PATIENTS AND METHODS: Patients with biopsy-proven CTCL that expressed CD25 on > or = 20% of lymphocytes were assigned to one of two dose levels (9 or 18 microg/kg/d) of denileukin diftitox administered 5 consecutive days every 3 weeks for up to 8 cycles. Patients were monitored for toxicity and clinical efficacy, the latter assessed by changes in disease burden and quality of life measurements. Antibody levels of antidenileukin diftitox and anti-interleukin-2 and serum concentrations of denileukin diftitox were also measured. RESULTS: Overall, 30% of the 71 patients with CTCL treated with denileukin diftitox had an objective response (20% partial response; 10% complete response). The response rate and duration of response based on the time of the first dose of study drug for all responders (median of 6.9 months with a range of 2.7 to more than 46.1 months) were not statistically different between the two doses. Adverse events consisted of flu-like symptoms (fever/chills, nausea/vomiting, and myalgias/arthralgias), acute infusion-related events (hypotension, dyspnea, chest pain, and back pain), and a vascular leak syndrome (hypotension, hypoalbuminemia, edema). In addition, 61% of the patients experienced transient elevations of hepatic transaminase levels with 17% grade 3 or 4. Hypoalbuminemia occurred in 79%, including 15% with grade 3 or 4 changes. Tolerability at 9 and 18 microg/kg/d was similar, and there was no evidence of cumulative toxicity. CONCLUSION: Denileukin diftitox has been shown to be a useful and important agent in the treatment of patients whose CTCL is persistent or recurrent despite other therapeutic interventions.

Phase II study of dolastatin-10 in patients with hormone-refractory metastatic prostate adenocarcinoma.

Dolastatin-10 is a natural, cytotoxic peptide with microtubule-inhibitory and apoptotic effects. It has demonstrated in vitro and in vivo efficacy in the DU-145 human prostate cancer model. A Phase II clinical trial was designed in patients with hormone-refractory prostate cancer. Dolastatin-10 was administered at a dose of 400 microg/m2 i.v. every 3 weeks. Dose escalation to 450 microg/m2 was permitted. Toxicity evaluation was conducted every 2 weeks, and assessment of response was done at the end of every two cycles. Sixteen patients were enrolled between October 1998 to December 1999. The median age was 71 years (range, 59-79 years). Median prostate-specific antigen value was 108 ng/ml (range, 15.3-1672 ng/ml). Of the 15 eligible patients, 7 were Caucasian and 8 were African-American. Eight patients had bone-only metastases, and seven had measurable disease with or without bone metastases. A total of 56 cycles have been administered. Only 2 patients required dose adjustment because of toxicity, and in 5 patients, dose escalation was feasible to 450 microg/m2. The major toxicities observed were grade 3 and 4 neutropenia in 8 patients and grade 3 neuropathy in 1 patient. All 15 patients are evaluable for response. Three patients demonstrated stable disease; 2 of these had bone disease, and 1 had nodal metastasis. All others had disease progression. Dolastatin-10 is very well tolerated in this elderly, pretreated population but lacks significant clinical activity as a single agent.

Periodic fever and pharyngitis in young children: a new disease for the otolaryngologist?

OBJECTIVE: A clinical entity consisting of periodic fever associated with aphthous stomatitis, pharyngitis and cervical adenitis termed "PFAPA syndrome" in young children (<5 years old) may be unfamiliar to otolaryngologists. We present our 5-year experience of PFAPA syndrome. DESIGN: Case series. SETTING: Tertiary academic. PATIENTS: A 5-year retrospective chart review for children (<5 years old) who have undergone tonsillectomies with and without adenoidectomies was conducted. Medical records from subjects who underwent the procedures for recurrent pharyngitis were reviewed with reference to a history of periodic fever and stomatitis associated with pharyngitis. INTERVENTIONS: Tonsillectomy with and without adenoidectomy. MAIN OUTCOME MEASURE: The objective measure was a comparison of the number of visits to the primary care physician for pharyngitis associated with fever in a 3-month period before and after the surgical intervention. The subjective measure was a telephone interview evaluating preoperative and postoperative symptoms. RESULTS: Of the 117 patients identified, 22 (19%) underwent surgery for recurrent pharyngitis. Five subjects (average age, 2.5 years) were identified as having PFAPA syndrome. The average number of preoperative PFAPA-related complaints was 11.6 compared with 0.2 for the number of postoperative PFAPA-related complaints (P=.03). CONCLUSIONS: Our experience suggests that PFAPA syndrome is an uncommon disease. Most of these children have undergone workup(s) for sepsis performed by their pediatricians because of the associated high fever. The clinical history of this cohort was quite distinctive. This small sample suggests a significant decrease if not cessation of pharyngitis following surgical intervention.

Cerebrospinal fluid profile in patients with acute Kawasaki disease.

BACKGROUND: Kawasaki disease (KD) is an acute vasculitis of infancy and early childhood for which there is currently no diagnostic test. The clinical presentation of KD may initially resemble other infectious diseases, including bacterial or viral meningitis. For this reason lumbar puncture (LP) is sometimes performed during the evaluation of these patients. To understand the range of cerebrospinal fluid (CSF) changes that may be associated with acute KD, a retrospective review of unselected KD patients from three pediatric centers was performed. METHODS: Retrospective chart review was performed on KD patients evaluated during the first 10 days of illness who had an LP performed before the administration of intravenous gamma-globulin. RESULTS: During the 6.5-year study period, 46 KD patients underwent LP as part of their clinical evaluation. Of these patients 18 (39.1%) had CSF pleocytosis, 1 (2.2%) had a CSF glucose <45 mg/dl and 8 (17.4%) had an elevated CSF protein. Of the patients with CSF pleocytosis, the median white blood cell count was 22.5 cells (range, 7 to 320 cells), with a median of 6.0% neutrophils (range, 0 to 79%) and 91.5% mononuclear cells (range, 11 to 100%). CONCLUSIONS: In the present series approximately one-third of KD patients who underwent an LP had CSF pleocytosis with a mononuclear cell predominance. No patient had significant hypoglycorrhachia, and elevation of the CSF protein was uncommon. CSF abnormalities were similar between US and Japanese KD patients. The basis for the CSF pleocytosis in acute KD patients remains unknown.

Kawasaki disease. The mystery continues.

Kawasaki disease is an acute systemic vasculitis of unknown cause first described in Japan in 1967. It affects children younger than 10 years, predominantly those younger than 3 years. Children of Asian ancestry are more commonly affected than white children. The diagnosis is made when 4 of the following 5 signs or symptoms are present with fever for at least 5 days: polymorphous rash; conjunctival injection; oral mucosal changes; cervical lymphadenitis; and erythema, swelling, or desquamation of the hands and feet. Various symptoms may be seen also, among them pronounced irritability, arthralgia, and abdominal pain. No diagnostic test exists, and clinicians must carefully exclude diseases that mimic Kawasaki disease. In addition to the above clinical findings, Kawasaki disease causes aneurysm formation in medium-sized arteries, particularly the coronary arteries. Found in about a fourth of patients, these lesions may persist, scar with stenosis, or resolve angiographically. The treatment consists of administering high-dose aspiring and intravenous immune globulin, with the goal of relieving acute illness and minimizing sequelae. Although most respond rapidly, almost 10% of children do not improve clinically with treatment. Complications of Kawasaki disease include myocardial infarction, which may occur during acute illness or later, as a result of coronary abnormalities.

Intravenous gamma-globulin treatment and retreatment in Kawasaki disease. US/Canadian Kawasaki Syndrome Study Group.

OBJECTIVE: To determine the prevalence and outcome of intravenous gamma-globulin (IVIG) retreatment in patients with Kawasaki disease (KD). METHOD: Multicenter, retrospective survey of all children with KD evaluated at nine clinical centers across North America during a 15-month period. RESULTS: Data were available for 378 patients. At 48 h after completion of the initial IVIG infusion, 50 patients (13.2%) remained febrile, 29 (58.0%) of whom were retreated with IVIG, including 4 (13.8%) with coronary artery abnormalities before their first IVIG infusion. Among 25 retreated patients with a normal baseline echocardiogram, 5 (20.0%) developed coronary abnormalities and were termed "treatment failures." Among the 323 patients with a normal baseline echocardiogram, only 9 (2.8%) were treatment failures; treatment failure occurred in 4 of 282 (1.4%) patients who became afebrile post-IVIG and in 5 of 41 (12.2%) patients with persistent or recrudescent fever after their first course of IVIG therapy (P=0.002). CONCLUSIONS: The overall prevalence of new coronary abnormalities in KD patients treated with IVIG and aspirin remains low. Persistent or recrudescent fever after the first course of IVIG was associated with an increased risk of treatment failure (P=0.002). IVIG retreatment in patients who remain febrile after the first course of IVIG is now common (58.0%), although the efficacy of this practice requires assessment with a randomized trial.

Simultaneous administration of a diphtheria and tetanus toxoids and acellular pertussis vaccine with measles-mumps-rubella and oral poliovirus vaccines.

OBJECTIVE: To compare the safety and immunogenicity of Lederle Laboratories' (Pearl River, NY) diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine with diphtheria and tetanus toxoids and whole-cell pertussis (DTwP) vaccine when administered simultaneously with measles-mumps-rubella (MMR) vaccine and trivalent oral poliovirus (OPV) vaccine at 15 to 16 months of age. DESIGN: Randomized and double-blind. SETTING: Two general pediatric practices. PARTICIPANTS: Ninety-seven infants, aged 15 to 16 months, who had received three previous DTwP immunizations. SELECTION PROCEDURES AND INTERVENTIONS: Healthy children received the DTaP or DTwP vaccine. Infants received the MMR vaccine at a separate site and the OPV vaccine concurrently. Blood was obtained on day 0 and at 6 weeks. Adverse events were recorded by parents at specified times after immunization. MEASUREMENTS/RESULTS: Within 3 days of immunization, DTaP vaccine recipients had less fever, drowsiness, and irritability (P = .01, .04, .01, respectively). They also experienced less tenderness, erythema, and induration (.001, .001, and .002, respectively). There was no difference in the frequency of adverse reactions 6 to 14 days after immunization. Enzyme-linked immunosorbent assays were used to determine all antibody values. Antibody responses to filamentous hemagglutinin and pertussis toxoid were significantly greater in the DTaP group (P = .0001 and .02, respectively). Immune responses to the other measured antigens were similar. CONCLUSIONS: Simultaneous administration of the Lederle DTaP with MMR and OPV vaccines did not interfere with antibody response to pertussis antigens measured or measles, mumps, or rubella viruses and was associated with fewer local and systemic adverse events during the first 3 days following immunization when compared with the simultaneous administration of the DTwP, OPV, and MMR vaccines. We conclude that the DTaP vaccine can be administered at 15 months of age concurrently with the MMR and OPV vaccines.

Diphtheria-tetanus toxoids-pertussis vaccination does not increase the risk of hospitalization with an infectious illness.

The purpose of this study was to determine whether children hospitalized with a primary diagnosis of infection were more likely than matched controls to have had a diphtheria-tetanus toxoids-pertussis immunization in the 30 days before hospitalization of the case. Cases were less likely than controls to have received an immunization (P = 0.003). They were also less likely to have been breast-fed (P < 0.001) and to have had a well-child care clinic visit (P = 0.01). Cases were significantly more likely to be preterm (< 38 weeks gestation), low birth weight (< 2500 g) and attending day care than their matched nonhospitalized controls (P = 0.003, 0.03 and 0.002, respectively). This study demonstrates no association between receipt of diphtheria-tetanus toxoids-pertussis immunization and subsequent hospitalization for an infectious illness.

Maximal voluntary work and cardiorespiratory fitness in patients who have had Kawasaki syndrome.

To assess the natural history of Kawasaki syndrome and its effect on maximal voluntary work and cardiorespiratory fitness, we performed cycle ergometry testing in 47 patients who had had the syndrome. Forty-one patients performed maximal effort as judged by achievement of 95% predicted heart rate response. Oxygen consumption, carbon dioxide production, and minute ventilation were performed in 23 patients. There was no difference in maximal voluntary work (total work, mean power) or maximal oxygen consumption between case subjects and control subjects. There were no differences between patients with and those without aneurysms. Serial exercise studies were performed in 10 patients; of these, two with initially normal exercise study findings had decreased maximal voluntary work and oxygen consumption with ischemic changes, and both were at high risk for the development of stenotic or occlusive coronary arteries. The other eight patients had normal cardiorespiratory reserve and no ischemic changes with serial studies. These results suggest that patients have normal cardiorespiratory fitness after Kawasaki syndrome. With the development of ischemic heart disease, they may have decreased cardiorespiratory reserve. Serial evaluation of cardiorespiratory fitness may demonstrate ischemic heart disease.

Safety and immunogenicity of acellular pertussis vaccine combined with diphtheria and tetanus toxoids in 17- to 24-month-old children.

A double-blind, randomized, controlled trial comparing 4 lots of acellular pertussis-diphtheria tetanus toxoids vaccine (APDT) to whole cell DTP vaccine in 397 children was conducted at 7 clinical centers. Children were immunized at 17 to 24 months of age and sera were obtained pre- and postimmunization. Sera were analyzed for antibody to pertussis antigens (pertussis toxin, filamentous hemagglutinin, with a molecular weight of 69,000 (69k) outer membrane protein and agglutinogens) and to diphtheria and tetanus toxoids. Information concerning local reactions and systemic events was collected daily for 10 days postimmunization. The acellular vaccine produced significantly fewer local reactions than whole cell DTP. Parents reported that drowsiness or fretfulness occurred significantly less often in APDT vaccine recipients compared with whole cell DTP recipients. Fever greater than or equal to 38.3 degrees C occurred in 8% of APDT vaccine recipients and in 15% of whole cell DTP vaccine recipients (P = 0.06). The only significant difference in immune response to pertussis antigens between the two vaccines was for filamentous hemagglutinin (P less than 0.01) for which significantly higher antibody concentrations were found in the APDT vaccine group. We conclude that this APDT vaccine is safe and immunogenic when administered as a booster dose to 18-month-old children.

Selective expansion of T cells expressing T-cell receptor variable regions V beta 2 and V beta 8 in Kawasaki disease.

Kawasaki disease (KD) is an acute vasculitis complicated by the development of coronary artery abnormalities. The etiology of KD is unknown. Based on the observation that KD is associated with marked activation of T cells and monocyte/macrophages, we hypothesized that KD may be caused by a superantigen [e.g., a bacterial toxin that stimulates T cells expressing particular T-cell receptor beta chain variable (V beta) gene segments]. Peripheral blood T cells from patients in the acute and convalescent phases of KD and from various control groups were analyzed for T-cell receptor V beta gene expression by using a quantitative PCR technique and cytofluorographic analysis with available anti-V beta monoclonal antibodies. Patients with acute KD demonstrated significantly elevated levels of circulating V beta 2+ and V beta 8.1+ T cells compared to the other control groups. none of the other 20 V beta populations analyzed by quantitative PCR were found to be significantly elevated. Using flow cytometry, we confirmed a significant elevation of T cells reactive with anti-V beta 8.1 and the lack of change in several other V beta subsets--i.e. V beta 5.1, -5.2, -6.7, and -12. During the convalescence phase of KD, there was a reduction in the abnormal levels of V beta 2+ and V beta 8.1+ T cells. These observations suggest that KD may be caused by a superantigen and may provide insight into the nature of the etiologic agent.

A single intravenous infusion of gamma globulin as compared with four infusions in the treatment of acute Kawasaki syndrome.

BACKGROUND: Treatment of acute Kawasaki syndrome with a four-day course of intravenous gamma globulin, together with aspirin, has been demonstrated to be safe and effective in preventing coronary-artery lesions and reducing systemic inflammation. We hypothesized that therapy with a single, very high dose of gamma globulin would be at least as effective as the standard regimen. METHODS: We conducted a multicenter, randomized, controlled trial involving 549 children with acute Kawasaki syndrome. The children were assigned to receive gamma globulin either as a single infusion of 2 g per kilogram of body weight over 10 hours or as daily infusions of 400 mg per kilogram for four consecutive days. Both treatment groups received aspirin (100 mg per kilogram per day through the 14th day of illness, then 3 to 5 mg per kilogram per day). RESULTS: The relative prevalence of coronary abnormalities, adjusted for age and sex, among patients treated with the four-day regimen, as compared with those treated with the single-infusion regimen, was 1.94 (95 percent confidence limits, 1.01 and 3.71) two weeks after enrollment and 1.84 (95 percent confidence limits, 0.89 and 3.82) seven weeks after enrollment. Children treated with the single-infusion regimen had lower mean temperatures while hospitalized (day 2, P less than 0.001; day 3, P = 0.004), as well as a shorter mean duration of fever (P = 0.028). Furthermore, in the single-infusion group the laboratory indexes of acute inflammation moved more rapidly toward normal, including the adjusted serum albumin level (P = 0.004), alpha 1-antitrypsin level (P = 0.007), and C-reactive protein level (P = 0.017). Lower IgG levels on day 4 were associated with a higher prevalence of coronary lesions (P = 0.005) and with a greater degree of systemic inflammation. The two groups had a similar incidence of adverse effects (including new or worsening congestive heart failure in nine children), which occurred in 2.7 percent of the children overall. All the adverse effects were transient. CONCLUSIONS: In children with acute Kawasaki disease, a single large dose of intravenous gamma globulin is more effective than the conventional regimen of four smaller daily doses and is equally safe.

Clinical and epidemiologic characteristics of patients referred for evaluation of possible Kawasaki disease. United States Multicenter Kawasaki Disease Study Group.

STUDY OBJECTIVES: (1) To determine those diseases that most often mimic Kawasaki disease (KD) in the United States. (2) To examine the physical findings and laboratory studies that influenced experienced clinicians to exclude the diagnosis of KD. (3) To compare epidemiologic features of patients with KD and patients referred for evaluation of possible KD in whom alternative diagnoses were established. DESIGN: Case comparison study. SETTING: Seven pediatric tertiary care centers. PATIENTS: Consecutive sample of 280 patients with KD and 42 comparison patients examined within the first 14 days after onset of fever. MEASUREMENTS AND MAIN RESULTS: (1) Infectious diseases, particularly measles and group A beta-hemolytic streptococcal infection, most closely mimicked KD and accounted for 35 (83%) of 42 patients in the comparison group. (2) The standard diagnostic clinical criteria for KD were fulfilled in 18 (46%) of 39 patients in whom other diagnoses were established. (3) Patients with KD were significantly less likely to have exudative conjunctivitis or pharyngitis, generalized adenopathy, and discrete intraoral lesions, and more likely to have a perineal distribution of their rash. The patients with KD were also more likely to have anemia and elevated erythrocyte sedimentation rate; leukocyte count less than 10 X 10(3)/mm3 and platelet count less than 200 X 10(3)/mm3 were significantly less prevalent in patients with KD. (4) Residence within 200 yards of a body of water was more common among KD patients. CONCLUSIONS: (1) Measles and streptococcal infection should be excluded in patients examined for possible KD. (2) Laboratory studies that may be useful in discriminating patients with KD from those with alternative diagnoses include hemoglobin concentration, erythrocyte sedimentation rate, and serum alanine aminotransferase activity. (3) Residence near a body of water may be a risk factor for the development of KD.

Outbreak of Kawasaki syndrome in Denver, Colorado: association with rug and carpet cleaning.

Between October 1984 and January 1985, the largest outbreak of Kawasaki syndrome reported to date in the continental United States (62 cases) occurred in the Front Range of the Rocky Mountains, extending from Colorado Springs, Colorado, to Cheyenne, Wyoming. Fifty-two (84%) of these Kawasaki syndrome patients lived in the Denver metropolitan area. A case-control study revealed that 16 (62%) of 26 Kawasaki syndrome patients compared with 10 (20%) of 49 matched control subjects had a history of exposure to shampooed (19%) or spot-cleaned (81%) rugs or carpets within 30 days of the Kawasaki syndrome onset date (odds ratio = 5, P less than .01). The time of exposure to shampooed or spot-cleaned rugs or carpets for 9 of 10 Kawasaki syndrome patients who had a single exposure and for all 6 Kawasaki syndrome patients who had multiple exposures were clustered within an interval 13 to 30 days before the onset of illness. Although the reason for this unusually large outbreak remains obscure, it is the third in which a statistically significant association between Kawasaki syndrome and rug or carpet cleaning has been found.
