Multicentric, multifocal, and recurrent osteoid osteoma of the hip: first case report.
2019
Abstract Background Osteoid osteoma is a benign bone-forming tumour, which very unfrequently has multifocal or multicentric presentation. We report the first known case of a multicentric, multifocal and recurrent osteoid osteoma treated using radiofrequency ablation. Case presentation A 39-year-old man with two-year history of left hip pain was admitted at our Institution. The pain was more intense during the night and partially relieved by salicylates. Pelvis CT demonstrated two lytic lesions (8 and 7 mm, respectively) with surrounding sclerotic reactive bone, both with a central focal area of high attenuation, located in the femoral neck and along the anterior portion of the acetabulum, r…
Early Denosumab for the prevention of osteoporotic fractures in breast cancer women undergoing aromatase inhibitors: A case-control retrospective stu…
2021
BACKGROUND: Aromatase inhibitors (AIs) might have a detrimental impact on bone health in breast cancer (BC) women. Denosumab has been shown to reduce the risk of fractures, but the appropriate time for starting is yet to be clearly defined. OBJECTIVE: To evaluate the effects of early treatment with Denosumab (⩽ 12 months after starting AIs) compared to a delayed treatment in BC women. METHODS: In this retrospective case-control study, we included medical records of BC post-menopausal women, treated with AIs therapy; they were divided as: study group (starting Denosumab ⩽ 12 months after AIs) and control group (> 12 months). At the baseline (T0) and at 18 months (T1), we evaluated the lum…
Periodontal therapy for patients before and after radiotherapy : a review of the literature and topics of interest for clinicians
2018
Background To review and discuss important topics regarding periodontal treatment pre- and post-radiotherapy for head and neck cancer in human patients; to discuss the references for adequate techniques, the appropriate moment for tooth extractions and periodontal management; and to discuss the prevention of osteoradionecrosis. Material and Methods Thirty-nine studies including original studies, randomized clinical trials (RCTs) and reviews were searched in online databases MEDLINE (PubMed) and the Cochrane library. No year of publication restriction was applied. Results Language was restricted to English, and the following Medical Subject Heading terms were used: radiotherapy, radiation th…
Studie zur intraarteriellen Mono- und Polychemotherapie von Mundh�hlen- und Oropharynxkarzinomen: Methotrexat (MTX) im Vergleich zur Kombination Vinc…
1982
In einer vergleichenden Studie wurde bei Karzinomen der Mundhohle und des Oropharynx der zytostatische Effekt einer intraarteriellen Monotherapie mit Methotrexat (MTX) einer Polychemotherapie mit Vincristin-Methotrexat-Bleomycin-Cisplatin (VMBP) gegenubergestellt.
Ancient Schwannoma of the hard palate. An uncommon case report and review
2013
Schwannoma or neurilemmoma is an infrequent benign tumor in the oral cavity that originates from the Schwann cells on the neural sheath of the peripheral nerves. Schwannomas are frequently located in the soft tissues of head and neck region, but only a 1 to 12% of them are located in the oral cavity. Some histological variants of schwannoma have been described including the cellular, plexiform, epithelioid, ancient, and melanocytic types. The “ancient schwannoma” is an uncommon variant of this tumor that shows specific histological characteristics, and is rare in the oral cavity with less than 15 cases described on the literature. Most of them were located in the tongue or in the floor of t…
Mapping the centers performing endocrine neck surgery in Italy
2020
Background. Quality of care and provider’s experience seem to be strictly connected in any field of surgery. Aim of this study is to identify a method to classify the centers on the basis of the number of thyroidectomies and parathyroidectomies performed. Methods. We listed 666 centers performing endocrine neck surgery in 2015, from the database of the Italian Health Ministry. We performed a descriptive statistic analysis with a dedicated software. We identified the outliers, according to a previous literature review, in those centers performing >1000 and < 10 thyroidectomies, >100 and < 3 parathyroidectomies and we excluded them to our analysis. The remaining centers were group…
Immunohistochemical analysis of cancer-associated fibroblasts and podoplanin in head and neck cancer
2019
Background To immunohistochemically evaluate the association between the presence of cancer-associated fibroblasts (CAFs) and the tumour expression of podoplanin (PDPN) in head and neck squamous cell carcinoma (HNSCC) and their association with clinicopathological variables. Material and Methods A tissue microarray (TMA) with biopsy sections from patients diagnosed with HNSCC was stained with antibodies against the CAFs marker, α-smooth muscle actin (α-SMA), and PDPN. We subsequently evaluated their expression to determine the association between them and with clinicopathological variables including age, primary tumour site, TNM stage, and tumour differentiation grade. Results Positive reac…
A possible inflammatory reaction in a lateral neck cyst (branchial cyst) because of odontogenic infection
1994
Abstract We present the case of a woman who suffered from an acutely infected diffuse mass in the right neck. This mass had grown rapidly after difficult extraction of a tooth. Histologic analysis of the excised material revealed a lateral neck cyst with a lymph node that showed signs of an acute inflammation near the cyst. These findings support the theory that a preexisting lateral neck cyst may be “activated” by an intraoral inflammation. The different theories of the origin of lateral neck cysts are presented and discussed in the context of the case description.
Ultrastructural localization of Ca2(+)-binding sites in the middle ear mucosa of the rat.
1990
Cations were precipitated with potassium-pyroantimonate in the middle ear mucosa of the rat and the distribution of the formed precipitates was studied by electron microscopy. The precipitate density in various cells of the different epithelia of the middle ear mucosa was determined on electron micrographs by counting the number of precipitates per unit area. Electron spectroscopic imaging was also performed to obtain information about the spatial distribution of the precipitates and their elemental composition.
