Frontal sinus osteoma and palpebral abscess: Case report

2005

Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases; there are often no symptoms and they are diagnosed by chance during an x-ray examination. The symptoms are usually headaches and those secondary to ocular or neurological complications. The therapy to be preferred is surgery. The authors describe a case of frontal osteoma complicated by frontal sinusitis and palpebral abscess.

Vascular modifications within a choroidal osteoma

1993

We report a case of choroidal osteoma followed-up for 7 years. During this lapse of time the choroidal osteoma showed slight enlargement, development of subretinal hemorrhage and modifications of intratumoral vascularization. Some large intratumoral vessels visible at first examination disappeared at follow-up, while other vessels not observed before developed. The changes in the vascularization of the choroidal osteoma denote profound dynamics in the processes of osseous rearrangement of the tumor.

Nutrition-related health problems in a wealthy 17-18th century German community in Jelgava, Latvia.

2012

The aim of this research is to assess the presence of stress in a high status German population from Jelgava, Latvia. The skeletal material used in this study came from a recently excavated church cemetery, with most of the burials dating to the 17-18th centuries. In total, 108 individuals (80 adults and 28 non-adults) were analysed for evidence of scurvy, rickets/osteomalacia and anaemia. The presence of scurvy and healed rickets/osteomalacia could not be confirmed in any adult individual. Among non-adults, a possible diagnosis of scurvy was considered in six individuals, and active rickets was suggested in two others. Cribra orbitalia in adult and non-adult individuals also argued for the…

Hereditary familial polyposis and Gardner’s syndrome: Contribution of the odontostomatology examination in its diagnosis and a case description

2005

La poliposis adenomatosa familiar (PAF) y su variante fenotípica, el síndrome de Gardner, constituyen una infrecuente patología hereditaria autosómica dominante. Se caracterizan por el desarrollo, generalmente durante la segunda y tercera década de la vida, de múltiples pólipos adenomatosos en el colon y en el recto. Estos pólipos tienen un riesgo elevado de transformación maligna subsiguiente, cosa que suele ocurrir en las décadas tercera y cuarta de la vida. Las manifestaciones fenotípicas de la PAF pueden ser muy variadas. Así, además de los pólipos colorrectales, los individuos afectos pueden presentar manifestaciones extracolónicas, entre las que se destacan: pólipos gastroduodenales, …

Hemangiopericytoma: A cause of recurrent epistaxis

2020

Hemangiopericytoma is a soft tissue tumor with histological variability and unpredictable clinical and biological behavior. this disease is uncommon in the head and neck and the growth pattern is unspecific; thus, diagnosis is often made by exclusion. A 43-year-old woman presented with a story of recurrent epistaxis associated to a growing mass in the paranasal sinus and a paraneoplastic syndrome. the imaging revealed an hypervascular tumor in the right nasal cavity and obliteration of all the ipsilateral sinus cavities. after biopsy the lesion was removed with resolution of epistaxis and paraneoplastic syndrome. There has been no evidence of disease recurrence in 3 years of follow-up. Our …

Radiofrequency ablation of osteoid osteoma

2018

Osteoid osteoma is a benign bone neoplasm with a reported incidence of 2-3% among all bone primary tumors. Although it is a small and benign lesion, it is often cause of patient complaint and discomfort. It is generally characterized by a long lasting, unremitting pain that typically exacerbates at night, often leading to sleep deprivation and functional limitation of the skeletal segment involved, with a significant reduction of patient daily life activities and consequent worsening of the overall quality of life. Over decades, complete surgical resection has represented the only curative treatment for symptomatic patients. In the last years, new percutaneous ablation techniques, especiall…

Mandibular osteoma as a cause of ankylosis and progressive trismus.

2021

Osteomas are benign tumours of bone tissue restricted to the craniofacial skeleton. The aim of this article is to present and discuss the demographic and clinical aspects and the management of craniomaxillofacial osteomas. When the patient was submitted from primary care to our hospital, he was 68 years old, and he had ankylosis of the temporomandibular joint for the previos 4 years. A CT scan was performed, finding a giant mandibular osteoma. Conservative treatment and radiological follow-up were carried out with clinical stability. Osteomas more often are seen in the paranasal sinuses and in young adults, with no differences in gender. Most are asymptomatic, but they can cause local probl…

Vitamin D substrate-product relationship in idiopathic hypercalciuria.

2007

Absorptive hypercalciuria (AH) is associated with elevated levels of 1,25-dihydroxyvitamin D (1,25(OH)(2)D). While no increase of 1,25(OH)(2)D after oral administration of 25-hydroxyvitamin D (25OHD) at high doses has been claimed in normal subjects, a substrate-product relationship has been reported in normal children, young people after UV irradiation, older persons, postmenopausal women, primary hyperparathyroidism, renal failure, osteomalacia, and sarcoidosis. No data of this relationship in AH is available. To investigate 25OHD-1,25(OH)(2)D substrate-product relationship in AH, 161 AH patients (mean age 60.9+/-11.7 years) and 110 age- and sex-matched controls (mean age 61.5+/-12.4 year…
