Salivary gland tumors in patients with necrotizing sialometaplasia: a case series

2013

Case report of necrotizing sialometaplasia

2010

Introduction: Necrotizing sialometaplasia is a rare inflammatory necrotizing reactive process that can involve minor and major salivary glands. Gland tissue ischaemia has been proposed as the aetiology. Case Report: A 21-year-old woman was referred with a 1-week history of bilateral painful swelling of the palate, with the development of two deep ulcers after the first 3 days. Ulcer edges were elevated but not indurated, and the bases had a necrotic appearance. An incisional biopsy of the margin of one ulcer confirmed the diagnosis of necrotizing sialometaplasia. The ulcers spontaneously healed within 8 weeks without treatment. Discussion: The clinical and histological similarity between th…

SEVERE STREPTOCOCCUS PYOGENES SURGICAL SITE INFECTION AFTER INGUINAL LIPOMA REMOVAL

2019

Surgical site infections (SSI) are a common cause of health care-associated infections. They are localized in the surgical incision site and can lead to deep tissues spreading. Among the wide spectrum of SSIs , we will consider specifically group A streptococcus cellulitis. This kind of infection can have a negative evolution and result in necrotizing fasciitis (NF), previously known as streptococcal gangrene. The term NF indicates a rare necrotizing infection involving any of the soft tissue layers that still have a high mortality rate from 7% to 76%. An early diagnosis and urgent treatment are key to ensuring the safety of the patients’ life. A 64-year-old man underwent a complete surgica…

Epigenetic Regulation of Early- and Late-Response Genes in Acute Pancreatitis

2015

Abstract Chromatin remodeling seems to regulate the patterns of proinflammatory genes. Our aim was to provide new insights into the epigenetic mechanisms that control transcriptional activation of early- and late-response genes in initiation and development of severe acute pancreatitis as a model of acute inflammation. Chromatin changes were studied by chromatin immunoprecipitation analysis, nucleosome positioning, and determination of histone modifications in promoters of proinflammatory genes in vivo in the course of taurocholate-induced necrotizing pancreatitis in rats and in vitro in rat pancreatic AR42J acinar cells stimulated with taurocholate or TNF-α. Here we show that the upregulat…

Shanghai Fever: Not Only an Asian Disease

2022

Objectives: To describe a case of Shanghai fever disease and to analyze other published reports in non-Asiatic countries, defining clinical characteristics and highlighting that this is not only an Asian disease. Study design: A computerized search without language restriction was conducted using PubMed and Scopus; all references listed were hand-searched to identify any other relevant literature. An article was considered eligible for inclusion in the systematic review if it reported cases with Shanghai fever described in non-Asiatic countries. Our case was also included in the analysis. Results: Ten articles reporting 10 cases of Shanghai fever disease were considered. Fever, diarrhea and…

Fungal Necrotizing Scleritis After Intravitreal Injection Therapy

2020

PURPOSE To report a case of infectious necrotizing scleritis secondary to Aspergillus terreus after intravitreal injection therapy. METHODS This is a case report with literature review. RESULTS A 98-year-old woman receiving intravitreal aflibercept injections for neovascular age-related macular degeneration in the left eye presented with severe pain, redness, and purulent discharge at the injection site. She was initially treated with topical fortified antibiotics, and clinical improvement was achieved, although microbial cultures showed negative results. Two months later, she presented with severe ocular pain and was diagnosed with anterior necrotizing scleritis. Scleral scrapings were col…

Chronic ulcerative stomatitis : a systematic review of the clinical and microscopic features

2019

Made available in DSpace on 2020-12-12T02:29:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-11-01 Background: the purpose of this study was to perform a systematic review regarding clinical and histopathological characteristics, immunopathological findings, and treatment for chronic ulcerative stomatitis (CUS). Material and Methods: articles in English, published from January 1962 up to November 2017, assessing clinical and immunological features, treatment, and follow-up of patientes with CUS, were retrieved from three databases (PubMed, Cochrane Library and SCOPUS). A manual literature search was also conducted. A total of 12 studies met inclusion criteria, therefore, were anal…

Aussagefähigkeit und Stellenwert von bildgebender Diagnostik und Duplexsonographie bei Neugeborenen mit nekrotisierender Enterokolitis

1994

In this prospective study 101 sonographic examinations of superior mesenteric artery blood flow velocities, indices and blood flow volume were consecutively performed in 41 newborn to diagnose necrotising enterocolitis (NEC). Intramural and portal venous gas was also estimated. The artifacts of air in the AMS and the portal system were examined in an experimental study. The results of sonography and abdominal radiography were equivalent in the case of definitely established NEC, portal venous gas being more sensitive to detection by sonography. Abdominal radiography was indicated as the primary examination in case of a clearly identified clinical course. Sonography should be performed so th…

What guidelines tell us about acute pancreatitis. A review of the last international guidelines

2014

Background Since the Atlanta Symposium several guidelines and consensus conferences have been published to improve the management and understanding of patients with acute pancreatitis. Herein, a review of the most recent guidelines on acute pancreatitis is carried out, trying to find differences and similarities.

Congenital malformations and perinatal morbidity associated with intestinal neuronal dysplasia.

1998

A close relation between different forms of dysganglionosis such as intestinal neuronal dysplasia (IND) type B and aganglionosis has been established. No systematic analysis of other malformations and diseases accompanying IND has been made as yet. Congenital malformations and perinatal morbidity were analyzed in 109 patients with IND seen at the Department of Pediatric Surgery in Mainz from 1977 to 1996. IND was associated with Hirschsprung's disease in 47 cases; 22 children with IND had other abdominal malformations, including anal atresia, rectal stenosis, sigmoidal stenosis, ileal atresia, pyloric stenosis, and esophageal atresia. A cystic bowel duplication, a choledochal cyst, and a pe…
