Incidence and predictive factors for complications after uterine leiomyoma embolization.

STUDY QUESTION: What is the risk of complications after uterine leiomyoma embolization and what are the factors associated with complications? SUMMARY ANSWER: The cumulative risk of complications after embolization is relatively low even in the long term, but submucosal leiomyoma location may increase the risk. WHAT IS KNOWN ALREADY: A broad spectrum of complications after leiomyoma embolization have been described with widely varying rates. There is uncertainty over the actual risk of complications and the factors associated with this risk. STUDY DESIGN, SIZE, DURATION: This was a prospective cohort study of 288 consecutive women undergoing leiomyoma embolization in the general gynaecology clinic of a university teaching hospital between January 2001 and December 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS: Complications occurring after embolization were categorized as major or minor according to the severity of their impact on health, the level of care required and the outcome. Cumulative complication rates were estimated by survival analysis and log-rank tests according to baseline variables. Multivariable Cox proportional hazards analysis was performed to adjust for confounders. MAIN RESULTS AND THE ROLE OF CHANCE: There were 48 patients who experienced a complication at a median of 5 months (95% confidence interval, 4.1-11.4) after embolization. Complications were minor in 38 patients and major in 10 patients. The cumulative overall complication rate was 13% (95% CI, 9.0-17.0) at 6 months, 16% (95% CI, 11.0-20.0) at 1 year, 17% (95% CI, 12.0-22.0) at 3 years and 18% (95% CI, 12.9-22.8) at 5 years. The most frequent complication (19/48, 39.6%) was leiomyoma expulsion, which occurred spontaneously in 13 (68.4%) of these cases and required assistance in 6 (31.6%) cases. Eight (2.8%) patients underwent re-intervention, including six hysteroscopic myomectomies, one laparoscopic myomectomy and one hysteroscopic adhesiolysis, as a result of a complication. Submucosal leiomyoma location was the only baseline variable associated with an increased risk for complications [Hazard ratio (HR), 2.28, 95% CI, 1.24-4.18, P = 0.008]. LIMITATIONS, REASONS FOR CAUTION: Our population did not include women of African descent, who have been reported to be at higher risk of post-procedural complications compared with Causcasian women. If such women were involved in the study, higher morbidity rates might have been observed. WIDER IMPLICATIONS OF THE FINDINGS: Women with submucosal leiomyomas at the time of embolization are more likely to have post-procedural complications. This is important new information for counselling patients contemplating this therapeutic approach. STUDY FUNDING/COMPETING INTERESTS: The authors have no competing interests to declare. The study was not supported by any external grant.

Fertility-sparing surgery in ovarian cancer extended beyond the ovaries: a case report and review of the literature.

BACKGROUND: Much attention has been recently focused on the role of fertility-sparing surgery in patients with ovarian cancer. However, few data are currently available on the feasibility of conservative approaches in women with disease extending beyond the ovaries. AIM: This review article aims at summarizing the oncologic and obstetric outcome of patients with stage II-III ovarian cancer treated with fertility-sparing surgery. We also describe a successful conservative management of a stage IIC endometrioid ovarian carcinoma. METHODS: A literature search through Medline was carried out to locate published articles using the following keywords for selection: 'Fertility-sparing surgery and ovarian cancer'. From every single case series, we retrieved data on patients with stage II-III disease submitted to conservative surgery. RESULTS: We identified 21 patients with stage II-III disease receiving fertility-sparing surgery. Recurrent disease was observed in 9 women (42.8%), and 5 (23.8%) of them died of disease. In contrast, a successful obstetric outcome has been reported in 3 cases (14.2%). CONCLUSIONS: Radical surgical staging remains the standard of care for all women with stage II-III disease. A fertility-sparing approach may be considered only in the presence of a favorable histology and a very strong fertility desire.

[Bacteremia by enterobacteria in adults from a university hospital: a five year analysis]. / Bacteriemia por enterobacterias en adultos en un hospital universitario: análisis de cinco años.

Bacteremia continues to be one of the main causes of morbidity and mortality in adult patients despite the existence of numerous antimicrobial agents and an increase in support measures. The aim of this study was to analyze the cases of community and hospital-acquired bacteremia, by evaluating the prevalence of species, risk factors, source of infection and antimicrobial susceptibility of the microorganisms involved. From January 2000 to December 2004, 129 cases of bacteremia due to enterobacteria were detected in 45 outpatients (35%) and 84 inpatients (65%). The most common risk factors were neoplasia (33.3%) and diabetes (12.4%); being urinary (29.5%) and abdominal (13.9%) the most frequently found sources of infection. E. coli was the most common enterobacteria isolated in both populations, followed by Klebsiella spp. (21.7%), and Enterobacter spp. (12.4%). Klebsiella spp. bacteremia was most common in ICU patients and, together with Enterobacter spp., constituted the most antibiotic-resistant microorganisms.

Bacteriemia por enterobacterias en adultos en un hospital universitario: análisis de cinco años / Bacteremia by enterobacteria in adults from a university hospital: a five year analysis

La bacteriemia sigue siendo una de las causas más importantes de morbilidad y mortalidad en pacientes adultos, a pesar de los numerosos antimicrobianos hoy disponibles y del aumento de las medidas de soporte. El objetivo del presente estudio fue analizar los episodios de bacteriemia por enterobacterias adquiridas en la comunidad y durante la hospitalización registrados durante un período de cinco años, estableciendo la prevalencia de especies, los factores de riesgo y los focos, así como la sensibilidad a los antimicrobianos de los microorganismos involucrados. Entre enero de 2000 y diciembre de 2004 se registraron en el Hospital Nacional de Clínicas de Córdoba 129 episodios de bacteriemias por enterobacterias: 45 correspondientes a pacientes ambulatorios (35%) y 84 a hospitalizados (65%). Los factores de riesgo más frecuentes fueron neoplasia (33,3%) y diabetes (12,4%); y los focos más habituales el urinario (29,5%) y el abdominal (13,9%). La enterobacteria aislada con mayor frecuencia en ambas poblaciones fue E. coli, con una incidencia media del 53,5%, seguida de Klebsiella spp. (21,7%) y Enterobacter spp. (12,4%). Las bacteriemias por Klebsiella spp. fueron más comunes en UTI. Esta especie junto con Enterobacter spp. fueron las bacterias más resistentes a los antimicrobianos ensayados.

[Isolation of enterococci species causative of infections and sensitivity to antimicrobial drugs]. / Aislamiento de especies de enterococos causantes de infecciones y su sensibilidad a los antimicrobianos.

Between April 1, 1999 and June 30, 2000, 144 isolates of enterococci (one per patient) from cultures of several anatomic sites were collected. One hundred and nineteen (82.6%) E. faecalis, 11 (7.6%) E. faecium and 14 (9.7%) of other species (5 E. raffinosus, 4 E. avium, 3 E. casseliflavus, 1 E. pseudoavium, and 1 E. dispar) were associated with clinical infections. The most common sites of isolation were: the urinary tract 54.9%, abdominal cavity 12.5%, surgical wounds 12.5%, abscesses 6.9% and diabetic foot 6.2%. High-level resistance to gentamicin or streptomycin or both was detected in 48.6% of the isolates. E. faecium and E. raffinosus were significantly more resistant than E. faecalis to ampicilin and imipenem. None of the strains exhibited beta-lactamase activity. One strain of E. faecium (0.7%) was resistant to vancomicin and teicoplanin (Van A phenotype) and two strains of E. casseliflavus (1.4%) showed low level of resistance to vancomicin (Van C phenotype). Because of these diverse antimicrobial resistance mechanisms, successful treatment and control of enterococcal infections with current antimicrobial agents are becoming increasingly difficult.

[Single dose of fleroxacin for the treatment of adult acute diarrhea]. / Monodosis de fleroxacina para el tratamiento de la diarrea aguda estival en el adulto.

The purpose of this work was to evaluate the efficacy and safety of a single dose of 400 mg of fleroxacin for the empiric antibiotic treatment of acute diarrhea in adult patients. A prospective, double-blind, placebo-controlled, randomized trial was designed. All the adult patients who consulted in our hospital for acute diarrhea from December 1994 to April 1995 were included. 72 patients were randomized to receive a single dose of fleroxacin 400 mg and 73 were placebo. Thirty-eight patients in each group were evaluable for efficacy. Between both groups there were not statistically significant differences in age, sex, number of loose stools per day at inclusion, days since the onset of symptoms up to inclusion, other symptoms than diarrhea at inclusion, percentages of bacterial pathogens and parasites isolated and symptomatic treatment indicated. At the third day since inclusion, clinical cure occurred in 72.2% of the patients receiving fleroxacin, compared with 36.4% of those receiving placebo; p = 0.002. The mean +/- SD time to cure was 2.2 +/- 1.2 days in the fleroxacin group and 3.2 +/- 2.0 days in the placebo group; p = 0.01. Twenty-eight and 16.7% of patients reported adverse effects in the fleroxacin and placebo groups respectively; p = 0.3. It is concluded that a single dose of fleroxacin 400 mg is an effective and safe alternative for the empiric antibiotic treatment of acute diarrhea in adults.

[Native-valve endocarditis produced by Lactobacillus casei sub. rhamnosus refractory to antimicrobial therapy]. / Endocarditis de valvula nativa producida por Lactobacillus casei sub, rhamnosus refractaria al tratamiento con antimicrobianos.

Lactobacillus endocarditis is a rare infection. In fact, only 42 cases have been described in the literature from 1938 up to date. In only 17 previously reported cases have patients been cured with medical therapy alone. Although infections produced by Lactobacillus spp, have been described in our country, none of them included endocarditis. We report herein a case of endocarditis due to a vancomycin-resistant strain of Lactobacillus casei sub. rhamnosus in a 29-year-old man with prolapse of the mitral valve. He required surgical replacement of his valve because of the poor response to antimicrobial therapy with penicillin and gentamicin. The patient displayed a successful clinical outcome, with no evidence of recurrence along the subsequent 2 years. We point out the need to accurately identify Lactobacillus spp. in isolates from blood cultures of patients with endocarditis, since these bacteria may often be mistaken for other species more frequently associated to this infection, which usually respond to conventional antimicrobial therapy. Furthermore, we suggest that early surgical replacement should be considered when lactobacillus endocarditis is diagnosed.

Food allergy in atopic dermatitis: experimental observations.

Results of an investigation of 134 subjects with atopic dermatitis and 29 controls are described. The investigation involved: 1) an allergological enquiry into each patient's medical history, with particular reference to consumption of eggs, milk and fish; 2) a total IgE assay; 3) RAST with egg, milk, cod; 4) a challenge test. Recording of medical histories revealed the existence of clinical sensitivity to egg, milk and cod in respectively 21, 17 and 7 of the 134 subjects with atopic dermatitis, but in none of the controls. In the atopic subjects, RAST demonstrated egg, milk and cod antibodies in 37, 28 and 14 cases respectively, while of the controls only 2 had antibodies--and then in minimal amounts. The maximum incidence of egg and milk antibodies was demonstrated in the initial 3 years of life. Clinical sensitization to cod manifests itself in the form of attacks (urticaria, angi-oedema, vomiting) showing significant correlation between clinical history, results of RAST and the response to challenge, while in the case of sensitivity to eggs and, even less evidently, to milk, the symptoms are more often referred to as "exacerbation of the dermatosis" and the results of RAST, of challenging and the clinical history tend to be contradictory.
