Identification of a Unique Helicobacter Species by 16S rRNA Gene Analysis in an Abdominal Abscess from a Patient with X-Linked Hypogammaglobulinemia

2000

ABSTRACT A unique Helicobacter species, MZ640285, was isolated from a patient with X-linked hypogammaglobulinemia suffering from recurrent abdominal abscesses and was identified by 16S rRNA gene sequence analysis. In the phylogenetic tree, the isolate fell into a cluster which included Flexispira rappini , Helicobacter bilis , and Helicobacter sp. strain Mainz. Helicobacters are being increasingly recognized as pathogens in immunocompromised hosts. These fastidious bacteria are not easily cultured in the routine diagnostic laboratory, and this is the first report of their identification by 16S rRNA gene sequencing performed directly from a clinical specimen.

Histomorphological and Immunophenotypic Features of Pill-Induced Esophagitis.

2015

The aim of this study was to investigate histomorphological and immunophenotypic features in pill-induced esophagitis. We comparatively evaluated the histomorphological, immunophenotypic features of pill-induced esophagitis vs. reflux esophagitis, as well as clinical information and endoscopic findings. Fifty-two tissue pieces from 22 cases of pill-induced esophagitis, 46 pieces from 20 reflux esophagitis, and 16 pieces from 14 control samples were subjected to immunohistochemistry for inflammatory infiltrates (CD3 for T lymphocyte, CD20 for B lymphocyte, CD56 for NK cell, CD68 for macrophage, CD117 for mast cell) and eosinophil chemotaxis-associated proteins (Erk, leptin, leptin receptor, …

Contrast-Enhanced Ultrasonography With SonoVue

2009

Objective. We investigated the ability of contrast-enhanced ultrasonography with SonoVue (Bracco SpA, Milan, Italy), a sulfur hexafluoride microbubble contrast agent, to reveal differences between benign and malignant focal splenic lesions. Methods. In a prospective study we investigated 35 lesions in 35 patients (24 male and 11 female; mean age ± SD, 54 ± 15 years) with focal splenic lesions detected by B-mode ultrasonography. After intravenous injection of 1.2 to 2.4 mL of SonoVue, the spleen was examined continuously for 3 minutes using low–mechanical index ultrasonography with contrastspecific software. The final diagnosis was established by histologic examination, computed tomography, …

Brain abscess formation within an endodermal cyst of the frontal lobe: case report.

2009

A 38-year-old man with a right frontal lobe cyst was treated by endoscopic cystoventriculostomy in 1998. Cyst capsule histology revealed surprisingly an endodermal cyst. The patient was reoperated for cyst expansion by endoscopic re-cystoventriculostomy in 2005. In 2007, the patient suffered from brain abscess formation within the cyst which was punctured. The history was positive for a dental infection. In 2008, a recurrent brain abscess in the cyst occurred. The cyst was completely resected. There was no history of trauma or sinusitis. In all, endodermal cysts may mimic a paraxial arachnoid cyst. It may predispose for recurrent brain abscess formation - especially due to bacteraemia. This…

Low rectal cancer: abdominoperineal resection or low Hartmann resection? A postoperative outcome analysis.

2011

BACKGROUND In distal rectum cancers, when the sphincters are not affected and it is not possible to perform a coloanal anastomosis because of the presence of comorbidities or the advanced age of the patient, a low Hartmann resection with total mesorectal excision can be performed. Low Hartmann resection is usually considered to be a shorter procedure and to have an inferior morbidity compared with abdominoperineal resection of the rectum. OBJECTIVE This study aimed to compare the postoperative outcome of a series of patients with low rectal cancer who have undergone either low Hartmann resection or abdominoperineal resection. DESIGN This study is a retrospective analysis of data collected i…

Is laparoscopic approach still a risk factor for postappendectomy intra-abdominal abscess?

2020

Background The impact of laparoscopic appendectomy (LA) on the incidence of intra-abdominal abscess (IAA) remains controversial. We aimed to identify risk factors for postappendectomy IAA and assess the impact of appendectomy approach in postoperative morbidity. Methods A retrospective single-center study including consecutive patients who underwent appendectomy for acute appendicitis between 2015 and 2018 was performed. Demographic, clinical, intraoperative, and perioperative variables were collected. Univariate and multivariate analyses was performed to detect independent risk factors for IAA. Comparison of LA and open appendectomy was conducted, and propensity score model (PSM) was used …

Importance of absorbable surgical sutures for the prevention of stitch abscess after surgery in patients with oral squamous cell carcinoma

2017

Background To elucidate the significance of absorbable surgical sutures in the occurrence of stitch abscess after surgery in patients with oral squamous cell carcinoma (SCC). Material and Methods The subjects were 251 patients who underwent excision and/or reconstruction and/or neck dissection for oral SCC using absorbable surgical sutures. Detection rates and characteristics of patients with stitch abscess were retrospectively evaluated by comparing between our present and previous data. Results There was only one stitch abscess among the 251 patients. A significant difference in the incidence of stitch abscess was found between the present data and our previous data. Of course, no signifi…

Clinical relevance of vegetation localization by transoesophageal echocardiography in infective endocarditis

1992

Infective endocarditis is associated with significant morbidity and mortality, with valvular destruction and congestive heart failure being more common in patients with echocardiographically discernible vegetations. The transoesophageal approach affords consistently high quality images with excellent structural resolution. Two-hundred and eighty-one patients with clinically suspected infective endocarditis were studied, to evaluate the prognostic value of ascertaining the site of vegetations. Among them were 118 patients with vegetations attached to the aortic or mitral valve. These patients were followed for a mean period of 14 months. Mitral valve vegetations were associated with a signif…

Prediction of rapid versus prolonged healing of infective endocarditis by monitoring vegetation size.

1991

The diagnostic value of transesophageal echocardiography in monitoring the clinical course has been evaluated in 83 patients with echocardiographic evidence of infective endocarditis. A total of 103 vegetations attached to the aortic or mitral valves were detected by use of the transesophageal approach. The patients were monitored for a mean of 74 weeks and underwent a minimum of two consecutive transesophageal echocardiographic examinations. Group A included patients with increasing or remaining constant size of vegetation (8.2 +/- 1.5 to 11.2 mm, p less than 0.05) during 4 to 8 weeks of antimicrobial therapy, whereas group B was formed by patients with decreasing vegetation size (8.3 +/- …
