Consumer acceptance for sheep milk-based yogurt-Evidence from a large sample of Italian consumers.

Testing consumer acceptance for a new product, such as the sheep milk-based yogurt, provides a measure of its market success, thus it informs producers on the effectiveness of their decision to transform sheep milk into yogurt to increase their revenues. This work explores to what extent consumers accept sheep milk-based yogurt and tests the role of personal-related factors and product-related features on shaping its acceptance. The study collects data from a representative sample of Italian yogurt consumers, and data are then analyzed via a logistic regression. Results show that male, highly educated, and high-income consumers are more likely than others to accept sheep milk-based yogurt. Findings suggest that consumers' food neophobia and variety seeking traits play a pivotal role in affecting consumer acceptance. Lastly, interest in nutritional and health-related yogurt features increases the probability of accepting sheep milk-based yogurt. Thus, sheep milk-based yogurt should be targeted at high-end male consumers and those interested in nutritional and health-related aspects of yogurt. Informing consumers about the sheep milk yogurt properties may further increase its acceptance and curb food neophobia, which we found to be one of the main barriers for the product acceptance. Future studies will explore consumer acceptance by using a real product and taste experiments.

Emerging trends in European food, diets and food industry.

Understanding how an adequate food security may be determined, how nutritional intakes evolve over time and are influenced by global dynamics are few of the questions scholars are trying to answer. In addition, a great interest is devoted to the changes in consumers' preferences and expectations as well as to the analysis of food innovations and their impact on the global market. We review the recent and emerging trends in food supply chains of selected sectors (fruits and vegetables, meat, and seafood), and deepen on emerging trends in the food industry. By presenting the evidence provided by the literature and emphasizing the unresolved research questions, we offer a critical view of future directions that should be followed by research agenda.

Duplication of the glans penis manifested at puberty.

We report the case of a complete duplication of the glans, with prepuce and a blind end urethra just proximal to the dorsal aspect of the balanopreputial fold. The malformation was not evident at birth and during childhood, and became manifest only at puberty, with the growth of the external genitalia. It was not associated with other urinary malformations. Surgical excision was easy and uneventful.

Craniopagus: the Thessaloniki-Rome experience.

OBJECT: A case of two female Greek twins conjoined at the left frontal and orbital regions is described. These conjoined twins were transferred to the Pediatric Neurosurgical Unit of the Gemelli Hospital, Catholic University Medical School, at the age of 4 months for possible surgical division. METHOD: Multiple diagnostic investigations, which included in particular advanced imaging techniques, demonstrated an independent cerebral vascularization of the two babies and excluded significant intracranial malformations. Such an accurate evaluation of the anatomy of the craniopagus at the level of the cranial junction allowed the feasibility of the surgical correction to be established. CONCLUSIONS: The operation was carried out by a multidisciplinary team in a single stage. The operating team included two distinct teams of neurosurgeons and anesthesiologists as well as a plastic surgeons' team. Both babies survived the operation. The postoperative course was uneventful. Both twins were discharged in good clinical and neurological condition after a 3-week period of hospitalization.

Soft tissue sarcomas: research of prognostic factors and therapeutics scheme.

The Soft Tissue Sarcomas shows consisting mortality that grazes 50%. Commonly the histologic type, the largeness of the tumor and the degree of malignity, are considered prognostic factors influencing the survival of patients affected from such tumor. The aim of our study is to characterize the new prognostic factors influencing the local recidives and metastatic dissemination. We have analysed 17 possible clinical and histologic prognostic factors in 80 patients affected of soft tissue sarcomas. The results have dimonstrated that: the compartimentality and the cellular differentiation seem to be more influent to the insurgence of local recidives and metastasis; while the low malignity degree, the wide surgical margins and the histopatological characters of benignity can influense positively the survival.

The integration of vascular surgical techniques with oncological surgical protocols in the treatment of soft tissue sarcomas of the limbs.

Soft tissue tumors, involving the vascular bundle, require a particular surgical approach: oncological and vascular surgical techniques must be integrated in order to perform a limb-saving surgery with adequate margins. Thirty-six soft tissue sarcomas of the thigh and popliteal region were treated from June 1999 to September 2002. Nineteen cases involving the vascular bundle were analysed and placed in two groups according to imaging and clinical information: Group A, 14 patients, with tumors close to femoral vessels without adventitial infiltration, and Group B, 5 patients, with vascular infiltration. Group A was treated with vascular blunt dissection performing adventitial excision. Group B was treated with vascular "en-bloc" resection and reconstruction. Imaging and clinical information together with surgical techniques, strategies and complications were analysed in order to plan the surgical approach in neoplastic vascular bundle involvement.

Fibro-cartilaginous lesions of the glenoid labrum in shoulder instability: a proposed classification using sagittal-oblique arthro-MRI.

PURPOSE: To propose a graded classification of lesions of the fibrocartilaginous glenoid labrum in traumatic dislocations of the shoulder, based on arthro-MRI in sagittal-oblique views. MATERIALS AND METHODS: Seventy-one patients with histories of chronic post-traumatic shoulder instability were studied from May 2000 to May 2001. MR images were obtained using superconducting magnets operating at 1 and 1.5 Tesla, with a dedicated shoulder coil. The study was carried out in combination with arthrography, with axial sections oriented perpendicularly to the longitudinal axis of the glena, oblique coronal sections parallel to the course of the supraspinous muscle tendon and oblique sagittal sections with axis parallel to the longitudinal axis of the glena. RESULTS: In one case an anatomical variant was found (Buford complex). In 18 patients a simple fissuration of the fibrocartilaginous glenoid labrum was found, whereas 28 patients displayed more extensive lesions affecting the middle-inferior portions of the labrum. In 15 patients the lesion extended to the middle-superior third of the glena, involving the middle glenohumeral ligament. In 9 cases, in addition to a complete lesion of the labrum, with typical "bucket-handle" appearance, a lesion of the superior and middle glenohumeral ligaments was also observed. DISCUSSION AND CONCLUSIONS: In traumatic shoulder dislocations it is essential to provide the surgeon with precise information regarding the location, extension and degree of damage to the capsule, ligaments and especially the labrum of the glenohumeral joint. On the basis of the results obtained in the sagittal-oblique sections we propose an MR-arthrography classification dividing lesions of the fibrocartilaginous labrum into 4 grades.

Combined radiological and surgical treatment of arteriovenous malformations of the head and neck.

Arteriovenous malformations (AVMs) are high-flow lesions. More than 50% of all AVMs are located in the head and neck region. They represent a therapeutic challenge because of their hemodynamic characteristics and their modality of growth. AVMs have a tendency to recur and often require radical resection, making surgical ablation and reconstruction difficult. AVMs require angiography not only for diagnostic purposes but as an initial therapeutic step in the form of embolization. Surgical ablation, which follows a few days after embolization, is facilitated by the reduction in vascularity and shrinkage of the lesion, both of which are afforded by the embolization. These benefits allow for less blood loss at the time of ablation, and less extensive resection. The authors report their experience with 16 patients with extracranial AVMs of the head and neck examined over the last decade.

Analysis of infiltrating epitheliomas of the nose examined from 1986 to 1995.

OBJECTIVE: Epitheliomas of the nose are frequently highly aggressive lesions with wide cutaneous-subcutaneous growth or an infiltrative growth pattern, especially when located at the columellar base, the alar base, and toward the inner chantal region. The aim of this study was to review this lesion with respect to location, recurrence, and treatment. METHOD: The authors present a retrospective study of 193 infiltrating epitheliomas of the nose examined between 1986 and 1995, including primary and recurrent cases. The authors term "clinically infiltrating epithelioma" any epithelioma whose growth implies the infiltration of the osteocartilaginous framework. RESULTS: The analysis of this case series, based on the histotype and the site of the epitheliomas, confirms that most of the primary histologically infiltrating basal cell carcinomas (BCCs) and of the recurrent BCCs are located at the alar base. The analysis of recurrences shows an aggressive local behaviour (multiple recurrences in the same site, change of the histologic pattern toward a more malignant one, etc.) suggesting that many of them were submitted to an insufficient physical or surgical treatment in the past. CONCLUSIONS: A radical surgical approach at the first signs of the primary lesion is mandatory in cases of nasal epithelioma.

Malignant tumors of the orbital region. Analysis of cases examined from 1986 to 1995.

OBJECTIVE: To present a retrospective study of 154 orbital tumors examined from 1986 to 1995. METHODS: We analyzed the clinical behavior and the degree of local malignity also in relationship with the particular anatomical characteristics of this site. RESULTS: In this are, it is not rare finding tumors with a scarce cutaneous extension but a deep involvement including the bone, or of recurrences after a previous insufficient treatment with an aggressive clinical course. CONCLUSION: The principles for the surgical approach are: exeresis as radical as possible, one-stage operation for tumoral resection and reconstruction, bringing of trophic tissue able to sustain any complementary treatment, easy and fast execution, and short clinical course.

Treatment of angiomas with sclerosing injection of hydroxypolyethoxydodecan.

The authors discuss the indications for hydroxypolyethoxydodecan in the sclerosing treatment of angiomas, with particular reference to cavernous, venous, and evolutive angiomas (ie, immature angiomas that fail to involute by eight to ten months). Moreover, the sclerosing agent may be employed, in connection with embolization and subsequent surgery, in arteriovenous angiomas with a relevant cutaneous-subcutaneous development. The authors have successfully used the "interstitial" sclerosing technique, according to Andrews' method. This technique involves interstitial injections to obtain the sclerosis of the thin threads of fibrous tissue stroma between the blood vessels. The sclerosing therapy may cause the complete regression of "low flow" angiomas or, at least, a partial reduction that simplifies the ensuing surgical excision. In the case of partial regression of the angioma obtained with the sclerosing therapy, the surgery of the remaining angioma causes a lesser degree of bleeding (especially in areas that do not particularly lend themselves to surgical exploration, ie, the oral cavity); an increased reliability in the radicality of the intervention (due also to the reduced size of the lesion); and better results from an aesthetic-functional point of view.

[Environmental and occupational factors in skin carcinogenesis. Indications for therapy and prevention]. / Fattori ambientali e professionali nella cancerogenesi cutanea. Indicazioni di terapia e prevenzione.

The authors review the environmental and occupational factors in cutaneous cancerogenesis, group them according to their characteristics, and in particular distinguish between factors of physical and chemical nature. The authors also discuss the influence of predisposing factors related to the somatic makeup (xeroderma pigmentosus) and to work environment. Particular emphasis is given to skin precancerous and therefore to the importance of a mass screening and an effective health education. The authors illustrate the disorder with their clinical pictures.

Steroid hormone receptors in female breast angiosarcomas.

Breast angiosarcoma is an extremely rare neoplasm usually affecting premenopausal women. Previous reports suggest that it is hormone-dependent. A case of primary breast angiosarcoma in a 16-year-old patient is presented in which the presence of estradiol, progesterone, and testosterone receptors was investigated. The histological findings initially revealed a simple angioma, but four months later the histological picture had completely changed, showing an angiosarcoma. Our data indicate a lack of receptors for steroid hormones in this tumor, which argues against the hypothesis presented in the literature.
