A computed tomography-based comparative cephalometric analysis of the Italian craniofacial pattern through 2,700 years.

The aim of our study was to define the changes in morphovolumetric features of neurocranium, basicranium and splanchnocranium in the population of Campania, southern Italy, over the last 2,700 years. This was a very intense period for this region from both historical and evolutionary perspectives and was marked by the succession of colonisations, dominations and invasions by several European and non-European peoples, events that profoundly influenced the original genetic heritage, which subsequently became more complex. Unlike most previous authors, we based our craniometric comparative analysis on multidetector computed tomography (MDCT) studies of contemporary and ancient series dating to between the seventh and fifth centuries B.C. of skulls found in the Etruscan necropolis of Pompei and Pontecagnano. MDCT is extremely reliable in identifying landmarks and measuring linear and angular indices through the use of multiplanar and tridimensional reformations. While highlighting a remarkable stability of 22/32 of the indices considered, as an effect of the role of the genetic heritage in preserving morphovolumetric features in a given population, statistical analysis showed some interesting results: the main changes concerned the splanchnocranium and the occlusion, indicating a higher sensitivity of these districts to environmental factors, mainly related to diet. Conversely, neurobasicranial complex morphovolumetric features remained amazingly intact. In particular, the neurocranium increased in overall capacity in response to the growing brain and changed shape with a progressive shift to a dolichocranic, flattened frontal pattern; the basicranium shape was preserved, as indicated by the stability of the cranial base (NSBa) angle over time. The splanchnocranium, on the contrary, has undergone a dramatic involution, even conditioning gnathic structures with changes in palatal shape (more acute) and in the relationship between the jaws on the sagittal plane, resulting in increased prevalence of Angle's class I and III malocclusions.

[Spigelian hernia: our experience during a decade]. / L'ernia di Spigelio: nostra esperienza in un decennio.

The Authors report a small series (three cases) of Spigelian hernias and underline the rarity of this pathology (0.2% in their series of hernias of the abdominal wall). They determine the anatomical features of the region, recall clinical features and discuss the most interesting points differential diagnosis and therapy.

[Primary mucinous carcinoid of the ovary]. / Il carcinoide mucinoso primitivo dell'ovaio.

A case of primary mucinous carcinoid of the ovary observed in a 52-year-old woman is reported after some remarks on the various histogenetic theories. The observation of this extremely rare cancer was fortuitous during surgery carried out for benign pathology in the contralateral organ. Careful postoperative controls absolutely excluded the possibility of a metastatic tumour. The patient was treated by combining surgery with chemotherapy and eight months after operation is apparently free of cancer.
