IL-10 and IL-10 receptor overexpression in oral giant cell lesions
2010
Objective: Central giant cell lesions (CGCL) and peripheral giant cell lesions (PGCL) occur in the jaws and contain osteoclast-like giant cells and mononuclear cells positive for the macrophage marker CD68. The participation of immune-inflammatory mechanisms has been proposed in the lesions development. As IL-10 is one of the most important anti-inflammatory cytokines and it is also an inhibitory cytokine to macrophage function and bone resorption, the purpose of the present study was to investigate its expression together with its receptor (IL-10R?) in CGCL and PGCL. Study Design: Six fragments of CGCL and seven fragments of PGCL were obtained by surgical excision. Frozen specimens were cu…
Juvenile Xanthogranuloma and Nevus Anemicus in the Diagnosis of Neurofibromatosis Type 1
2013
Importance The diagnosis of neurofibromatosis type 1 (NF1) is based on 7 clinical criteria. However, they are of limited value before the age of 2 years. Juvenile xanthogranuloma (JXG) and nevus anemicus (NA) are commonly observed in children with NF1 and may be useful diagnostic clues. Objectives To evaluate the frequency of JXG and NA, to describe their clinical features, and to determine their diagnostic value in patients with NF1. Design, Setting, and Participants Retrospective medical record review of outpatients seen between January 1, 2005, and December 31, 2011. University hospital dermatology department affiliated with the French NF1 referral center network. Patients with NF1 diagn…
A rare case of abdominal cocoon.
2013
Abdominal cocoon is a rare cause of intestinal obstruction usually diagnosed incidentally at laparotomy. It manifests by forming a membrane that typically encases the small bowel loops, leading to mechanical obstruction. Preoperative diagnosis is difficult. The etiology of this condition is not well understood; however, it is a form of chronic irritation and inflammation.A 33 years old male, from Bangladesh, presented to our emergency department complaining of abdominal pain, nausea, and vomiting. CT abdomen shows a picture of intestinal obstruction at the level of the small intestine. Intraoperative findings showed encapsulation of small bowel by a dense whitish membrane as a cocoon. Histo…
Otoneurological management of petrous apex cholesterol granuloma
2009
Objective: The aim of the study is to review the management of petrous apex cholesterol granuloma. The surgical approaches for drainage or total removal and the wait and see policy were analyzed, and outcomes were evaluated. Methods: Retrospective charts of 27 patients managed for petrous apex cholesterol granuloma with a minimum follow-up of 12 months were analyzed in a quartenary skull base center. Presenting symptoms and signs were recorded, and radiologic imaging was evaluated. Management options included wait and see policy and surgery by several approaches. Results: The mean age of patients affected by the lesion was 38.8 years. The mean follow-up was 56.7 months. Patients complained …
Sclerotherapy for the recurrent granulomatous epulis with pingyangmycin
2017
Background Relapse of granulomatous epulis is common after surgery because of local irritations, hormonal level in vivo, or incomplete resection. Currently, if recurrence occurs, then extraction of the teeth adjacent to the lesion is commonly performed, which may influence the aesthetics or masticatory function. Thus, a more effective and less aggressive treatment method is urgently demanded, particularly for the recurring lesion. This study investigated the effects of the intralesional pingyangmycin (PYM) injections for the recurrent granulomatous epulis and assessed the complications. Material and Methods A total of 16 patients with recurrent granulomatous epulis underwent intralesional P…
Treatment and its side effects in ANCA-associated vasculitides - Study based on POLVAS registry data.
2020
Abstract Purpose The aim of this study is to present the treatment modalities and associated side effects in a Polish nation-wide ANCA-associated vasculitides (AAV) patients’ cohort. Materials and methods Retrospective analysis of patients diagnosed with AAV between 1990 and 2016, included in the POLVAS registry was performed. Standard descriptive statistic methods were used with an emphasis on the treatment modalities. Results There were 625 patients diagnosed with AAV included in this study: 417 cases of granulomatosis with polyangiitis (GPA; 66.7%), 106 cases of microscopic polyangiitis (MPA; 17.0%) and 102 cases of eosinophilic granulomatosis with polyangiitis (EGPA; 16.3%). The mean ag…
The supracondylar approach to the jugular tubercle and hypoglossal canal.
1998
BACKGROUND Circumscribed lesions of the hypoglossal canal and of the jugular tubercle still remain a surgical challenge. So far, transpetrosal, transcondylar suboccipital, and extreme lateral approaches have been used to access this region. These surgical procedures bear a high risk for neurological deficits. Therefore, we introduce a new minimally invasive extradural approach to the hypoglossal canal that also allows access to the lateral aspects of the jugular tubercle. METHODS After a paramedian retromastoid skin incision, a basal suboccipital craniectomy lateral to the foramen magnum toward the jugular tubercle is performed. With this approach the occipital condyle and the lateral osseo…
Use of Biologics to Treat Relapsing and/or Refractory Eosinophilic Granulomatosis With Polyangiitis: Data From a European Collaborative Study.
2021
OBJECTIVE To describe the efficacy and safety of biologics for the treatment of eosinophilic granulomatosis with polyangiitis (EGPA). METHODS A retrospective European collaborative study was conducted in patients with EGPA who received treatment with biologics for refractory and/or relapsing disease. RESULTS Among the 147 patients with EGPA included in the study, 63 received rituximab (RTX), 51 received mepolizumab (MEPO), and 33 received omalizumab (OMA). At the time of inclusion, the median Birmingham Vasculitis Activity Score (BVAS) was 8.5 (interquartile range [IQR] 5-13) in the RTX group, while the median BVAS in the OMA group was 2 (IQR 1-4.5) and the median BVAS in the MEPO group was…
Immunological study of Melkersson-Rosenthal syndrome. Lack of response to food additive challenge
1995
Summary A study was made of six patients with Melkersson-Rosenthal syndrome (MRS) to establish the aetiological role of foodstuffs and/or additives and the possible associated immunological alterations. In all cases Melkersson-Rosenthal syndrome (MRS) was diagnosed both clinically and histologically, excluding other causes of orofacial granulomatosis (OFG). A detailed study of possible triggering factors was performed in all patients. Blood analysis, x-rays and cultures, were always within normal limits, with the exception of the finding of circulating immune complexes (CICs) in three patients with facial palsy associated, and C-reactive protein positivity in two patients who presented pers…
