Abstract

Ameloblastic carcinoma is a rare malignant odontogenic neoplasm with a poor prognosis. It can arise de novo or from a pre-existing ameloblastoma. Research into stemness marker expression in ameloblastic tumours is lacking. This study aimed to explore the immunohistochemical expression of stemness markers nestin, CD138, and alpha-smooth muscle actin (alpha-SMA) for the characterisation of ameloblastic tumours. Six cases of ameloblastoma and four cases of ameloblastic carcinoma were assessed, including one case of ameloblastic carcinoma arising from desmoplastic ameloblastoma. In all tumour samples, CD138 was positive, whilst alpha-SMA was negative. Nestin was negative in all but one tumour sample. Conversely, the presence or absence of these markers varied in stroma samples. Nestin was observed in one ameloblastic carcinoma stroma sample, whilst CD138 was positive in one ameloblastoma case, one desmoplastic ameloblastoma case, and in two ameloblastic carcinoma stroma samples. Finally, alpha-SMA was found positive only in the desmoplastic ameloblastoma stroma sample. Our results suggest nestin expression to be an indicator for ameloblastic carcinoma, and CD138 and alpha-SMA to be promising biomarkers for the malignant transformation of ameloblastoma. Our data showed that nestin, CD138, and alpha-SMA are novel biomarkers for a better understanding of the origins and behaviour of ameloblastic tumours.

Abstract

In this case report we describe the development in the cerebellopontine angle of a very rare tumor, ceruminous adenoma. In the few cases described in the literature this tumor occurred in the external acoustic meatus. In four cases it developed in the cerebellopontine angle by infiltration of the petrous bone or by subcutaneous spread. In the present case no connection was found between the cerebellopontine angle and the external acoustic meatus. The most likely pathogenetic hypothesis in this case is that of a tumor of dysembryogenetic origin.

Abstract

We compared the clinical, psychological and pharmacological characteristics of patients with familial migraine and patients with sporadic migraine. Five hundred and thirty consecutive new patients attending our Headache Center over a two-year period were involved in the study. The patients were divided into two groups: A. Familial migraine (famM)--at least one first-degree relative affected; B. Sporadic migraine (spoM)--no first-degree relative affected. Four hundred and twenty-four patients (80%) fulfilled the criteria for famM and 106 (20%) for spoM. The patients with famM showed a significantly (p0.01) earlier age at onset of the disease. No significant difference in all the remaining features examined was found. Our data suggest that famM and spoM represent a single disease entity.

Abstract

The role of foods as headache precipitants is still matter of debate. Several studies reported that dietary constituents may precipitate migraine attacks. Some authors reported that also tension type headache attacks may be provoked by foods. The purpose of this study was to evaluate the role of foods as headache triggers in both groups of patients.We compared the role of foods as headache trigger in patients with migraine and tension type headache. Three hundred and nine patients were involved in the study and divided into six groups: 1) migraine without aura, 2) migraine with aura, 3) episodic tension type headache, 4) chronic tension type headache, 5) migraine without aura associated with episodic tension type headache, 6) migraine without aura associated with chronic tension type headache.Approximately one third of the patients reported susceptibility to certain foods. The percentage of food sensitivity was not significantly different between patients with migraine or tension type headache. The foods more commonly reported as headache triggers were alcoholic drinks, chocolate and cheese. No difference in specific food sensitivity between groups was found. The comparison of food-sensitive with food non-sensitive patients showed no significant difference in the clinical features.Our study suggests that foods may trigger not only migraine but also tension type headache attacks.
