RESUMO

Few reports exist regarding the association between onychomadesis and an enterovirus infection presenting clinically as hand, foot, and mouth disease (HFMD). In February 2009, an outbreak of HFMD occurred in a Spanish nursery school, followed by onychomadesis 36-69 days later. Twelve of 17 children with HFMD developed nail shedding; enterovirus was detected in stool samples from eight (47%) of the 17. However, in only three of the children could an enterovirus serotype coxsackievirus B1 be identified. The epidemiological results of this study confirm onychomadesis as a complication in HFMD. In future outbreaks, molecular characterization of enterovirus from appropriate clinical samples should be studied.

RESUMO

OBJECTIVES: To offer a rationale for assigning a minimum score for risk of malnutrition for total proteins lower than 5g/dl and a scoring scale for our filter (FILNUT-Scale); and to analyse results of the MUST screening test performed on positive scores in the FILNUT nutritional filter and assess usefulness of said test in this population. METHODS: We searched the laboratory database for laboratory test orders (dated between 2004 and 2007) for which total proteins and albumin or cholesterol levels were determined, and we identified those with results for the above three parameters plus lymphocyte count. A limit (less than 5g/dl) was placed on the total protein level and the results for other parameters were not limited. Distribution curves for albumin and cholesterol were analysed. The same protocol was followed after establishing the CONUT score for each sample with the necessary parameters. From September 2007 to January 2008, the MUST test was performed on all FILNUT positives and we analysed how the degrees of risk corresponded. RESULTS: In 95% of the cases in which total proteins are lower than 5g/dl (n=1,176), albumin values are between 0.98 and 2.94g/dl, resulting in CONUT scores of 4 or 6 for albumin. Regarding total cholesterol, (n=761) 89.1% of the samples are lower than 180mg/dl, which accounts for one or two points in the score. In 98.79 % of the cases (n=490) that presented all four parameters, CONUT score was >/=5, which could be classified as medium or high risk. During the study period, 100% of the patients identified as medium or high risk by the FILNUT-Scale (n=568) tested as at-risk by MUST: of these, 421 (74.1%) were at high risk and 147 (25.9%) were at medium risk. CONCLUSIONS: Total proteins lower than 5g/dl determine a medium or high risk of malnutrition where a complete nutritional screening profile is lacking. This is why it should be included in the FILNUT-Scale with a score of five points. Performing the MUST test on patients with five or more points is efficient and provides clinical data needed for a complete assessment.

RESUMO

Microquasars are binary star systems with relativistic radio-emitting jets. They are potential sources of cosmic rays and can be used to elucidate the physics of relativistic jets. We report the detection of variable gamma-ray emission above 100 gigaelectron volts from the microquasar LS I 61 + 303. Six orbital cycles were recorded. Several detections occur at a similar orbital phase, which suggests that the emission is periodic. The strongest gamma-ray emission is not observed when the two stars are closest to one another, implying a strong orbital modulation of the emission or absorption processes.

RESUMO

BACKGROUND: Esophageal motility abnormalities have been observed in patients with gastroesophageal reflux disease. GOALS: The aim of the present study was to determine if esophageal motor disorders in patients with a positive response to the omeprazole test are related to the existence of reflux or they are concomitant findings. STUDY: A 24-hour pH monitoring and a stationary manometry were performed on 128 patients: 49 of them had normal manometry, 31 hypotensive lower esophageal sphincter, 29 motor disorder in esophageal body, and 19 hypotensive lower esophageal sphincter and motor disorder in esophageal body. RESULTS: We found an association between the presence of abnormal reflux and motor disorder in esophageal body (chi test; P < 0.05). However, ineffective esophageal motility was the disorder most strongly related to reflux, whereas the hypercontractile disorders were not clearly attributed to it. CONCLUSIONS: Esophageal manometric abnormalities should be considered cautiously before considering a motor disorder as a consequence of abnormal reflux.

RESUMO

BACKGROUND: Recent reports and a previous randomized trial conducted at the authors' institution suggested that a lower risk subset of children with febrile neutropenia under chemotherapy might benefit of an oral antibiotic outpatient approach. METHODS: The objective of this study was to test the efficacy of oral ciprofloxacin in the treatment of lower risk febrile neutropenia (LRFN) in children treated for malignant diseases. From November 1998 to December 1999, 93 episodes of LRFN in 87 children (median age, 5.5 years; range, 0.9-15.8 years) were included in a prospective randomized controlled single institution trial. Inclusion criteria included fever (> 38 degrees C), severe neutropenia (absolute neutrophil count, < 500/mm(3)), and lower risk features (e.g., absence of severe comorbidity factors, good clinical condition, negative blood cultures, control of local infection, prediction of a period of neutropenia less than 10 days after admission, and compliant parents). After 24 hours of a single intravenous ceftriaxone (100 mg/kg) plus amikacin (15 mg/kg) and completed risk assessment workup, patients were discharged and randomly allocated to two groups. Group A (48 episodes) received ciprofloxacin 20 mg/kg/day orally (p.o.) every 12 hours for 6 days. Group B (45 episodes) received intravenous ceftriaxone plus amikacin for 2 days more followed by cefixime (8 mg/kg/day p.o.) every 24 hours for 4 additional days. Failure was defined as the need of a second hospitalization during the same episode. RESULTS: Most of the patients (59% in Group A and 52% in Group B) were treated for malignant solid tumors. Fifteen (31%) children in Group A and 15 (33%) in Group B presented with fever of unknown origin (P value was not significant). No significant differences were found in sites of initial infection between both groups. Overall results in this study were excellent. Only one patient with respiratory failure was detected in Group B, who did well with secondary treatment. CONCLUSIONS: In febrile neutropenic children after anticancer therapy and lower risk features, oral ciprofloxacin for 6 days after 24 hours of intravenous ceftraxione plus amikacin appears to be as efficacious as intravenous ceftriaxone plus amikacin for 2 days more followed by cefixime for 4 additional days. These results contribute to strengthen the concept of LRFN.

RESUMO

To validate the use of a lower-risk mortality profile in pediatric febrile neutropenia during anticancer therapy and to evaluate the efficacy of a sequential parenteral-oral antibiotic treatment for these children, a prospective study was conducted between May 1997 and December 1999. During this period 247 episodes in 215 patients were included in the present study. Children with neutropenia (ANC < 500/mm3) and fever (> 38 degrees C) due to anticancer therapy were eligible for the study if they presented the following lower-risk conditions: absence of severe co-morbidity factors, good clinical condition, no risk clinical foci, no bacteremia, and responsible parents. They were initially treated with inpatient parenteral short course of ceftriaxone and amikacin followed by ambulatory oral cefixime or ciprofloxacin to complete 7 days. Mean age was 64 (range: 8-200) months. The most common underlying malignant disease was acute lymphoblastic leukemia in 48% (118) of cases and 57% (141) of patients had an indwelling central venous catheter. Clinical evidence of infection was found in 47% (122) of children and the most common site was the upper respiratory tract (81%). Mean period of fever was 1.1 days (r: 1-8) and the duration of neutropenia was 3.9 days (r: 1-9). Sixty-one% (150) of children was discharged with neutropenia. Mean time of hospitalization was 1.5 days. Four clinical failures were detected (1.6%). They all were satisfactorily treated with a secondary treatment and none underwent any major complications or died. The lower-risk profile used was safe and the sequential antibiotic therapy was adequate to manage febrile neutropenia in this subset of children.

RESUMO

OBJECTIVE: To investigate the clinical significance of the free-to-total prostate-specific antigen ratio (f/tPSA) and PSA density (PSAD) for prostate cancer detection in patients with intermediate tPSA levels (4-10 ng/ml). To establish a cutoff to discriminate between benign prostatic disease (BPH) and prostate cancer (CaP), avoiding unnecessary biopsies. METHODS: This prospective study included 136 men, aged between 54 and 85 (mean 70.6) years old. Urinary tract symptoms were present in these patients. Serum samples were obtained to measure tPSA, fPSA, and f/tPSA; digital rectal examination and transrectal ultrasound eight-sector biopsies were performed. Prostate volume was measured and PSAD calculated. The pathologic study, carried out in 113 patients, showed 82 with BPH and 31 with prostate cancer in various stages. RESULTS: There were no significant differences between patients with BPH and CaP when comparing tPSA, fPSA, f/tPSA or digital rectal examination. PSAD and prostate volume were significantly different in patients with BPH and CaP. With a sensitivity of 94% (78.5-99), the f/tPSA cutoff was 0.28 with a 11% (5.2-19.8) specificity. With a sensitivity of 96.2% (80.3-99.4) cutoff for PSAD was 0.109 and specificity 25% (15.5-36.6). CONCLUSIONS: In patients whose tPSA level is between 4 and 10 ng/ml, f/tPSA has no advantages over tPSA measurement for early detection of prostate cancer. DPSA can improve specificities, without compromising the detection of CaP.

RESUMO

BACKGROUND: Febrile neutropenia is a heterogeneous condition. Recently, several risk factors have been defined, permitting the definition of a lower risk group of patients who may benefit form less aggressive therapy. The use of an oral antibiotic approach was tested in the current trial. METHODS: From May 1997 to March 1998, 154 episodes of lower risk febrile neutropenia in 128 children with a mean age of 62 (range, 8-200) months were enrolled in this randomized, single-institution trial. Inclusion criteria were fever (> 38 degrees C), neutropenia (absolute neutrophil count < 500/mm(3)), lower risk features (i.e., absence of severe comorbidity factors, good clinical condition, negative blood cultures, control of local infection, no fever during the last 24 hours), and compliance of parents. After 3 days of ceftriaxone (100 mg/kg/day administered intravenously [i.v.]) every 12 hours plus amikacin (15 mg/kg/day i.v.) every 24 hours for 3 days, all patients were discharged and randomized to be allocated to 2 treatment arms. Group A (n = 74) received ceftriaxone cefixime (8 mg/kg/day administered orally) every 24 hours for 4 days, whereas Group B (n = 80) was treated with ceftriaxone plus amikacin for 7 days. Failure was defined as the need for second hospitalization during the same episode of neutropenia, or fever during the 7 days after discharge. RESULTS: Most of the patients (49% in Group A and 55% in Group B) had acute leukemia. Fifty-four (72%) children in Group A and 46 (56%) in Group B had fever of unknown origin (P = not significant [NS]). No significant differences were found in the sites of initial infection between the two groups. Overall results were outstanding, with a favorable outcome in 73 of 78 cases (98.6%) in Group A and 78 of 80 cases (97.5%) in Group B (P = NS). Three patients needed a second hospitalization due to failure of the initial therapy: one in Group A and two in Group B. All three did well with secondary treatment. CONCLUSIONS: In lower risk febrile neutropenic children receiving anticancer therapy, the efficacy of oral cefixime, given for 4 days after 72 hours of intravenous ceftriaxone plus amikacin, was similar to that of 7 days of parenteral ceftriaxone plus amikacin. The oral outpatient therapy approach to the treatment of lower risk febrile neutropenia after chemotherapy is safe and may be cost-saving. This strategy might be adopted as standard therapy in the future.

RESUMO

BACKGROUND: The overutilization of the hospital emergency areas (HEA) in recent years has been related to an inadequate functioning of the primary health care and can be corrected by the implementation of the primary health care reform. MATERIAL AND METHODS: Home interview of a sample of residents of the city of Mataró (Barcelona, Spain), where the primary health care reform affects to four of the seven basic health areas. Collection of information on health care utilization and attitudes to its use. RESULTS: Of the 1,974 studied subjects 27% (CI 95%, 25-29) reported to have used the HEA in the former year, and the frequency of visits was 0.48 (CI 95%, 0.44-0.54) per person. For the 1880 beneficiaries of the national health system, these results were somewhat lower between the users of reformed centres (27%, 0.46) than those of non-reformed centres (30%, 0.50) (p = NS); differences were attributed mainly to adult women. Users of reformed centres expressed more preference for the ambulatory in case of a non-severe emergency (37% and 17%; p < 0.0001) and consulted more often before going to the HEA (17 and 10%; p = 0.03). Among the reasons to go to the HEA, users of the reformed model perceived less necessity of an immediate action (43 and 52%; p = 0.05) and greater time barriers with the basic health areas (23 and 15%; p = 0.04). CONCLUSIONS: In spite of the lack of overall differences in the use of HEA between users of reformed centres and non-reformed centres we observed a lower utilization in some age and sex groups from reformed centres. Some elements of the demand of the HEA are more appropriate and attributed to the primary health care reform. However, the reasons prompting to use the HEA show that an unjustified utilization is still done, independently of the primary health care model.

RESUMO

We conducted a 6-year study of 110 patients with thyroid nodular disease in a previously goitrogenic area. The aim of the present work was to establish its incidence, to determine if multinodular goiter and autonomous thyroid nodule have the same analytical and clinical behaviour and to verify if the iodation campaign had resulted in the development of thyrotoxicosis induced by iodine. The results demonstrated an incidence of 0.4 per 1,000 population and per year. The two modalities of thyroid nodular disease did not present any clinical and analytical differences. 58.2% of the patients had hyperthyroidism, 53.1% of which were T-4 thyrotoxicosis, 12.5% T-3 thyrotoxicosis and 34.4%, subclinical hyperthyroidism. 8.2% of the patients under study had hyperthyroidism induced by iodine (Jod Basedow), with iodide excretion values higher that 3 standard deviations with respect to the population average (> 220 micrograms/g creatinine).
