Introduction

We present a new technique for the surgical treatment of haemorrhoids, consisting of the repositioning of haemorrhoid cluster, using a rotating Proctoscope called Hemor Pex System® (HPS). This procedure is performed as an outpatient procedure, with minimal postoperative pain and rapid integration into working life.

Objectives

To present the experience with this technique during 3 years of follow up in two institutions in Genoa, Italy.

Patients and methods

from January 2003 to June 2006, 1112 patients with grade II, III and IV haemorrhoids were operated on using the HPS technique, in two different hospitals. Prospectively analyzed the following parameters: postoperative pain, incidence of complications and recurrence of symptoms.

Results

A total of 1112 patients were operated, of whom 719 have completed the follow-up. The mean age was 47 years. In 92% of cases the intervention was performed under local anaesthesia. The average time of surgery time was 20+/−5 min. A total of 97% of patients were discharged at 6 h after surgery. The immediate postoperative pain, according to the Visual Analogue Scale (VAS): absent (0) in 38 cases, slight (1-3) in 431 cases, 218 medium and intense in 32 cases.

Conclusions

We believe HPS is a safe procedure, with a short learning curve for surgeons, and in particular leads to a great reduction in post-operative pain for the patient.  相似文献

异基因造血干细胞移植(hematopoieticcelltransplantation,HCT)后代谢综合征的发生主要由预处理导致的神经激素系统紊乱、血管内皮损伤、移植物的免疫和炎症作用以及继发的移植物抗宿主病及其治疗等引起。对代谢综合征及其组分(糖尿病、高血压、血脂紊乱等)的筛查可以尽早地调整治疗策略,控制危险因素的发生,进而降低远期的心血管疾病的发生率和致死率。为此,美国的研究人员回顾性分析了86例异基因HCT受者代谢综合征的发生情况,并与代谢综合征在普通人群中的流行情况进行比较。  相似文献

The mucosa of the gastric stump is considered at greater risk of dysplastic and neoplastic changes than that of the intact stomach. The combination of enteric reflux and Helicobacter pylori infection may have a synergistic damaging effect on the mucosa of the gastric remnant, both producing and increasing mucosal proliferation. The aim of this study was to assess whether the occurrence of H. pylori infection in the remnant mucosa of partially gastrectomized subjects for peptic ulcer disease is associated with an increase of the mucosal precursor lesions of malignancy. A series of 151 subjects who underwent partial gastrectomy for peptic ulcer disease were submitted to upper digestive endoscopy for long-term surveillance. Biopsy specimens of the gastric stump were tested for the occurrence of H. pylori infection and for the presence of precancerous mucosal lesions. The prevalence of H. pylori colonization in the remnant stomach was less than 30% and similar in subjects with different time intervals between gastrectomy and endoscopy. Age at surgery (χ2: p = 0.03) and H. pylori infection (χ2: p = 0.002) were significantly associated with the grading of mucosal lesions. The prevalence of normal mucosa was 10 times higher in H. pylori-negative patients as in H. pylori-positive ones (22.0% vs. 2.4%), and the prevalence of intestinal metaplasia was four times higher in H. pylori-positive patients than in H. pylori-negative ones (19.6% vs. 4.6%). We concluded that H. pylori infection may play a causal role in the development of gastric lesions in the operated stomach.  相似文献

Abstract We showed the ability of human dermal fibroblasts to take up Malassezia furfur and the effect of ketoconazole and cytoskeleton inhibitors, including cytochalasin D and colchicine, on invasivity. Engulfment was evaluated by May Grunwald Giemsa stain and confirmed by acridine orange staining and electron microscopy. Both revealed the different steps of engulfment, including a fusion event between lysosomes and phagosomes containing M. furfur. Subinhibitory concentrations of ketoconazole (5 μg/ml) reduced the invasive capacity compared to controls (52.0 ± 6.3 vs 10.0 ± 1.2). M. furfur induced changes in the cytoskeleton of human dermal fibroblasts, with signs of disaggregation of actin fibres. We also studied the effect of the cytoskeleton inhibitors, cytochalasin D (1 μg/ ml) and colchicine (1 μg/ml), on engulfment. Cytochalasin D, an inhibitor of actin polymers, inhibited the uptake of M. furfur by human dermal fibroblasts. Colchicine, a microtubule inhibitor, reduced the uptake of M. furfur less markedly. This suggests that the process of engulfment is F-actin-dependent, but the integrity of microtubules is also important in “non-professional” phagocytic cells such as dermal fibroblasts.

Respiratory complications are common in the patient with muscular dystrophy. The periodic clinical and instrumental respiratory evaluation is extremely important. Despite the presence in the literature of updated guidelines, patient associations often report lack of knowledge of these pathologies, particularly in peripheral hospitals. The purpose of this work, inspired by the Italian Muscular Dystrophy Association (UILDM) is to improve management of respiratory problems necessary for the management of these patients complex. To this end, the main items that the specialist can meet in the follow-up of these pathologies have been analyzed and discussed, among which the respiratory basal evaluation, the criteria of adaptation to non-invasive ventilation, management of bronchial secretions, situations of respiratory emergency, indications for tracheostomy and the subject of advance directives of treatment (DAT).Key words: respiratory failure, muscular dystrophy, cough efficacy, spirometry, polygraphy, non-invasive ventilation, arterial blood gases, cough machine, invasive ventilation, tracheostomy, mechanical ventilation  相似文献

BACKGROUND: There is substantial but not conclusive evidence that insulin resistance is related to left ventricular mass (LVM) in hypertensive individuals. To what extent this association is mediated by the relationship between plasma insulin and body size and build is still debated, and is poorly explored in nonhypertensive people. OBJECTIVE: To explore the relationship between insulin or insulin resistance and LVM in a population-based sample of nonhypertensive participants of the Gubbio Study. METHOD: Echocardiographic LVM was determined in 91 nondiabetic, nonhypertensive individuals aged 45-54 years, participating in a population-based screening. LVM normalized for height2.7 was used in the analyses; LV hypertrophy was defined as a value of > or = 50 g/m2.7 in men or > or = 47 g/m2.7 in women. Fasting plasma insulin and glucose were measured and the Homeostasis Model Assessment (HOMA) index was used as a measure of insulin resistance. RESULTS: LVM was positively and significantly correlated with body mass index (BMI) (P < 0.01), waist circumference (P < 0.01) and HOMA index (P < 0.05), whereas correlations with plasma glucose and triglycerides did not reach statistical significance (P = 0.07 for both); all correlations were offset after adjusting for BMI. Fasting plasma insulin and HOMA index were not significantly different in subjects with or without LV hypertrophy (70.8 +/- 27.8 vs. 77.7 +/- 29.6 pmol/l and 2.2 +/- 1.0 vs. 2.6 +/- 1.4, respectively). Bivariate analysis performed stratifying participants above or below the 75th percentile of the sex-specific distribution for BMI (29.1 and 29.4 kg/m2 for males and females, respectively) and plasma insulin (84 pmol/l for either gender), did not result in appreciable differences in LVM due to insulin levels. Similar results were obtained replacing the HOMA index for insulin in the analysis. CONCLUSION: In nonhypertensive individuals left ventricular mass is not associated with plasma insulin independently of body mass index.  相似文献

Chronic heart failure (CHF) is a leading cause of morbidity and mortality. Although a precise definition for a cut-off value of hemoglobin level for anemia is still lacking, it has recently been found to be a common complication in CHF, occurring in 10-20% of patients. There are several possible pathogenetic mechanisms for anemia in CHF, and a precise underlying cause is found in only a minority of patients. In CHF, more than 50% of anemia cases are considered to be 'anemia in chronic illness'. In CHF patients, low hemoglobin values directly relate to poor peak oxygen consumption, disabling symptoms, and impaired survival. Recent pilot studies showed that correction of anemia with erythropoietin and iron may lead to improvement in symptoms and exercise capacity. These issues need to be tested in larger, double-blind, randomized, placebo-controlled trials before anemia treatment becomes routine in patients with CHF.  相似文献
