Spontaneous echo contrast imaging in infective endocarditis: a predictor of complications?

1992

Infective endocarditis is associated with significant morbidity and mortality. Valvular destruction and congestive heart failure are more common in patients with echocardiographically detectable vegetations. In addition, spontaneous platelet aggregation is increased when vegetations are present on cardiac valves. The aim of the study was to assess the prognostic value of spontaneous echo contrast (SEC) imaging, as SEC is supposed to reflect red blood cell aggregates stimulated by platelet activity. We studied 293 patients with clinical signs of infective endocarditis. Vegetations, attached to the aortic or mitral valve, were found in 130 patients (44.4%) who were followed for a mean period …

Occurrence of silk stitch abscess after surgery in patients with oral squamous cell carcinoma

2012

Objectives: To elucidate the predisposing factors and clinical characteristics related to the occurrence of stitch abscess after surgery in patients with oral squamous cell carcinoma (SCC). Patients and Methods: The subjects were 232 patients who underwent excision and/or reconstruction and/or neck dissection for oral SCC using silk sutures for high ligation of the blood vessels. Detection rates and characteristics of patients with stitch abscess were retrospectively evaluated by comparing patients with and without stitch abscesses after surgery diagnosed by ultrasonography and findings of various modalities in 232 patients. Several echogenic dots with subtle acoustic shadows in a hypoechoi…

Severe versus Local Odontogenic Bacterial Infections: Comparison of Microbial Isolates

2007

<i>Aim:</i> It was the aim of this study to evaluate the clinical and microbiological differences between severe and local odontogenic abscesses. <i>Methods:</i> Thirty patients were prospectively enrolled. Sixteen of 30 patients suffered from a severe life-threatening abscess of the head and neck, whereas 14/30 patients presented with a localized submucous abscess. Anaerobic bacteria were identified and susceptibility testing was performed using E test strips for penicillin, amoxicillin + clavulanic acid, imipenem + cilastatin, clindamycin and metronidazole. <i>Results:</i> The mean duration until removal of all drains was 14.1 and 3.5 days, respectively…

Complications following the use of alloplastic materials in urogynecological surgery

2011

Abstract Study design 118 patients, who were admitted from 2005 to 2008 to our department due to complications following mesh implantation, were included in a retrospective survey. We investigated patient symptoms, findings and subsequent patient management. There was a re-evaluation of symptoms in a follow-up eight weeks after the revision procedure. Data from our urogynecological file archive were used. Results The main complaints were de novo urgency, pain and recurrent urinary tract infections. The main findings were mesh erosion and infections including abscess formations and osteomyelitis. Before being admitted to our department, 42 patients (35.6%) had already undergone at least one …

Abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar

2006

Aim  To discuss a rare, but severe complication arising following routine root canal treatment. Summary  An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the or…

Anal canal mixed adenoneuroendocrine carcinoma in a young patient misdiagnosed as anal abscess.

2021

Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare tumours of gastrointestinal tract, extremely rare in anal canal. We report a case of misdiagnosed MiNEN in a 38-year-old woman initially conservatively treated for a supposed anal fistula. In a second proctological evaluation, biopsy of the anal neoformation was performed and the histological specimen diagnosed a MiNEN. The complete staging showed a disseminate disease and the patient started a chemotherapy schedule. After 6 months, stable disease was revealed at the last imaging performed and radical surgery was offered to the patient that is actually on oncological follow-up without recurrence at 1 year.

Use of transoesophageal echocardiography in the diagnosis of abscess in infective endocarditis

1995

Transoesophageal echocardiography is invaluable clinically since it accurately images abscess cavities or aneurysms. It provides the information about the site and extension of abscesses which is needed by surgeons to time and define surgical intervention. Early diagnosis is advantageous, and abscesses should be expected in 5%-30% of patients with echocardiographically discernible vegetations. Since there is no 'abscess typical' organism, transoesophageal echocardiographic examination is helpful at the first indication of infective endocarditis, to identify high-risk patients. Involvement of the aortic valve, growth in the size of vegetations, and the presence of spontaneous echo contrast a…

Association between COX-2 rs 6681231 genotype and interleukin-6 in periodontal connective tissue. A pilot study.

2014

[Objectives] The aim of this pilot study was to investigate associations between IL-6 and COX-2 expression in gingival biopsies and both clinical diagnosis and genotypes in the IL-6 and COX-2 genes. [Design] A case-control study included 41 gingival biopsies obtained from Caucasian patients grouped according to clinical diagnosis of gingival health (n = 10), gingivitis (n = 15) or chronic periodontitis (n = 16). Immunohistochemistry analyses were performed to determine COX-2 expression in lamina propria, IL-6 expression in lamina propria and gingival epithelium and level of inflammatory cell infiltrate. Individual DNA was extracted and genotyped by real-time PCR for IL6 SNPs rs 2069827 and …

Spinal epidural abscess due to acute pyelonephritis

2022

Background: Spinal epidural abscesses are rare and are misdiagnosed in up to 75% of cases. Fever, back pain, and neurological deficits are part of the classical triad. Here, the authors report a patient with a L2–L5 spinal epidural abscess with the left paravertebral extension attributed to acute pyelonephritis. Case Description: A 54-year-old female presented with persistent low back pain and lower extremity weakness accompanied by paresthesias. Previously, she had been hospitalized with the left acute pyelonephritis. The lumbosacral MRI documented a T12/L5 anterior epidural abscess with ring enhancement on the contrast study; the maximum diameter of the abscess at the L2–L3 level contrib…
