Use of oxycodone in polytrauma patients: the "Gemelli" experience.

Introduction: This is the first study investigating the effect of oxycodone in polytrauma patients. The management of pain in polytrauma patients has become a very relevant issue. Nonsteroidal anti-inflammatory drugs (NSAIDs) represent the most used drugs in polytrauma patients, even though their use is associated with an increased hemorrhagic risk.

Lectin histochemistry for in situ profiling of rat colon sialoglycoconjugates.

The growing interest in glycoconjugates expressed and released by the epithelium of the intestinal mucosa is tightly related to the multiple functional roles attributed to sialic acid and its derivatives. In the present work, biotin and HRP conjugated lectins were used to detect the sialylation pattern and to identify specific structural features of sialoderivatives in the rat colon. In particular, the occurrence and distribution of sialic acids linked alpha2,6 to D-Gal/D-GalNAc and alpha2,3 to D-Gal were directly demonstrated with SNA and MAL II binding, respectively.

Probiotics: which and when?

There is a natural feeling between our intestinal flora and the gut. These microorganisms, living in the various tracts of human intestine, may affect the host homeostasis. Some of these bacteria can perhaps be a source of infection and sepsis when the bowel barrier is physically or functionally breached.

Regression of lactose malabsorption in coeliac patients after receiving a gluten-free diet.

Objective: In a recent study by our group, it was shown that a large proportion of patients with lactose malabsorption and with no bacterial overgrowth are affected by silent coeliac disease (CD). Our aim was to evaluate the effect of a gluten-free diet on lactose malabsorption assessed using the hydrogen lactose breath test (LBT) and also the relationship with normalization of duodenal biopsies in coeliac patients.

Material And Methods: Fifteen patients (11 F, 4 M; mean age 35.

Small intestinal bacterial overgrowth: diagnosis and treatment.

Small intestinal bacterial overgrowth (SIBO) is a clinical condition characterized by a malabsorption syndrome due to an increase in microorganisms within the small intestine. The main mechanisms restricting bacterial colonization in the upper gut are the gastric acid barrier, mucosal and systemic immunity and intestinal clearance. When these mechanisms fail, bacterial overgrowth develops.

Association between hypothyroidism and small intestinal bacterial overgrowth.

Objectives: Small intestinal bacterial overgrowth is defined as an abnormally high bacterial population level in the small intestine. Intestinal motor dysfunction associated with hypothyroidism could predispose to bacterial overgrowth. Luminal bacteria could modulate gastrointestinal symptoms and interfere with levothyroxine absorption.

Mandible metastasis as the first sign from primary adenocarcinoma of the lung.

Adenocarcinoma of the lung that metastasizes to the mandible is very uncommon; only a few cases have been described in the English-language literature. This article presents a metastasis from adenocarcinoma of the lung affecting the mandible of a 64-year-old woman, in which the first discovered metastatic lesion was detected before the primary tumor. The immunoreactivity for human thyroid transcription factor-1 (TTF-1) in the oral lesion was essential for determining the site and type of the primary tumor, as the patient showed no clinical or radiographic evidence of a tumor in the thyroid gland.

Villoglandular adenocarcinoma of the cervix: two new cases with morphological and molecular study.

In this paper, we report 2 new cases of villoglandular papillary adenocarcinoma (VGPA) of the cervix, a rare, well-differentiated form of cervical adenocarcinoma. Both patients were without medical complications or history of oral contraceptive use and were nonsmokers. Extended hysterectomy was performed in both cases.

Diagnosis and management of severe atherosclerosis of the ascending aorta and aortic arch during cardiac surgery: focus on aortic replacement.

Objective: Severe atherosclerosis of the ascending aorta and arch frequently causes difficulties during heart operations, hindering surgical manoeuvres and potentially leading to systemic embolism. The aim of our study was to assess the safety and effectiveness of replacing the atherosclerotic ascending aorta in this setting.

Methods: Aortic atherosclerosis was characterized by epiaortic ultrasonographic scanning in 90.

High dosage rifaximin for the treatment of small intestinal bacterial overgrowth.

Background: Rifaximin is a broad spectrum non-absorbable antibiotic used for treatment of small intestinal bacterial overgrowth. Doses of 1200 mg/day showed a decontamination rate of 60% with low side-effects incidence.

Aims: To assess efficacy, safety and tolerability of rifaximin 1600 mg with respect to 1200 mg/day for small intestinal bacterial overgrowth treatment.

Applicability of the Bethesda System 2001 to a public health setting.

Background: The degree of applicability of the Bethesda System 2001 (TBS 2001) for cervicovaginal cytology to a public health setting is unknown, and extrapolations from available data are unwarranted.

Methods: A "before/after" study design was used to evaluate the impact of TBS 2001 on an organized, population-based screening program in northern Italy. Between 2003-2004, 6 cytology laboratories converted from TBS 1991 to TBS 2001.

Histomorphometric evaluation of human sinus floor augmentation healing responses to placement of calcium phosphate or Ricinus communis polymer associated with autogenous bone.

Background: Prosthetic rehabilitation of the posterior maxilla with dental implants is often difficult because of proximity to the maxillary sinus and insufficient bone height. Maxillary sinus floor augmentation procedures aim to obtain enough bone with an association between biomaterials and autogenous bone.

Purpose: The purpose of this study was to evaluate histomorphometrically two grafting materials (calcium phosphate and Ricinus communis polymer) used in maxillary sinus floor augmentation associated with autogenous bone.

Hydrogen glucose breath test to detect small intestinal bacterial overgrowth: a prevalence case-control study in irritable bowel syndrome.

Background: Studies assessing the prevalence of small intestinal bacterial overgrowth in irritable bowel syndrome gave contrasting results. Differences in criteria to define irritable bowel syndrome patients and methods to assess small intestinal bacterial overgrowth may explain different results. Moreover, no data exist on small intestinal bacterial overgrowth prevalence in a significant population of healthy non-irritable bowel syndrome subjects.

Helicobacter pylori and extragastric diseases--other Helicobacters.

The involvement of Helicobacter pylori in the pathogenesis of extragastric diseases continues to be an interesting topic in the field of Helicobacter-related pathology. Although conflicting findings have been reported for most of the disorders, a role of H. pylori seems to be important especially for the development of cardiovascular and hematologic disorders.

Idiopathic chronic urticaria and celiac disease.

Idiopathic chronic urticaria (ICU) is a chronic relapsing cutaneous disease. Some case reports or studies on small series of celiac disease (CD) patients have suggested a possible association between CD and ICU. The aim of this study was to assess the prevalence of CD in a population of adults ICU patients with respect to healthy controls.
