CD44v6 and Nm23-H1 protein expression related to clinico pathological parameters in colorectal cancer.

OBJECTIVE: Nm23-H1 and CD44v6 expression has been shown to be correlated with the metastatic potential of colorectal cancer (CRC) in some studies but not in others. The present study was undertaken to evaluate immunohistochemically the expression of these markers and to correlate them with clinicopathological variables. MATERIALS AND METHODS: Archival tissues of 41 non metastatic colorectal cancers were histopathologically evaluated and stained with monoclonal antibodies versus Nm23-H1 and CD44v6. RESULTS: Expression of Nm23-H1 was detected in 73% (n = 30) of all CRC, and CD44v6 in 37% (n = 15) of all CRC. CD44v6 was found to be statistically associated with tumour grading differentiation (p < 0.03), but no correlation emerged between Nm23-H1 and CD44v6 and Dukes stage, site, peritumoral lymphocytic infiltration, venous infiltrating, perineural infiltrating, tumour budding, pushing and infiltrating tumour growth. CONCLUSION: Even if the results are not statistically significant, the authors noticed that the expression of Nm23-H1 was correlated with those histopathological parameters that indicate local disease progression and metastases.

[Breast carcinoma with neuroendocrine differentiation. Clinical case and review of the literature]. / Il carcinoma mammario con differenziazione neuroendocrina. Osservazione clinica e revisione della letteratura.

Female breast carcinoma with neuroendocrine differentiation is a lesion which can enhance of conventional therapy added with tamoxifene-octreotide association. The Authors report a case completely responsive after two years therapy, which grading was: pT4, N1biii, Mx, G2 staging III.

[Chronic periaortitis]. / La periaortite cronica.

The authors, o the basis of a retrospective analysis of a series of 13 cases of chronic periaortitis, after a review of the literature about the subject, discuss about the most recent theories about pathogenesis, pathological anatomy, diagnosis and treatment of this condition. At first the authors stress the importance of adopting the term chronic periaortitis to describe any idiopathic fibrotic retroperitoneal process, as a consequence of the well established relationship between the atherosclerotic abdominal aorta an the development of this condition. Histological, immunohistochemical and immunological studies, consented to clarify the pathogenesis o the lesion. CT or MRI currently makes the diagnosis but histological confirmation is desiderable. Surgical therapy plays still a fundamental role in the management of chronic periaortitis, but the use of immunosuppressive drugs is to be considered extremely promising.

[Role of total thyroidectomy in benign multinodular benign goiter]. / Il ruolo della tiroidectomia totale nella tireopatia nodulare plurifocale benigna.

The Authors report a review of the Literature and their personal series to evaluate the role of total thyroidectomy in the surgical management of non-toxic multinodular goiter. On the basis of the data obtained, the Authors consider total thyroidectomy the therapy of choice for this pathology.

[Reconstructive microsurgery]. / La microchirurgia ricostruttiva.

Since Microsurgery was born, it has been employed in different surgical fields offering more recently good chances even in sterility. Furthermore microsurgical techniques offer a great support to Plastic Surgery. In fact, it is possible to repair wide tissue damages of the skin, muscles or bones using free flaps. The percentage of success of this surgery increased the overall rate of success of surgical procedures. Therefore a close multidisciplinary relation between the different fields is absolutely required for a correct application of microsurgical techniques.

[Ambulatory surgery of varices: our experience]. / La chirurgia ambulatoriale delle varici: nostra esperienza.

The Authors, on the basis of their experience with 196 patients aged from 18 to 45, affected by relapsing varicose veins, stress the advantages of the outpatient treatment according to Muller's technique. For these lesions excellent aesthetic and functional results, easy surgical technique, low incidence of complications, prompt resumption to work were registered.

[Male infertility due to varicocele: their diagnosis and treatment. Our experience]. / L'infertilità maschile da varicocele: diagnostica e terapia. Nostra esperienza.

The Authors have examined, over a period of two years, 110 patients presenting with varicocele and infertility. Varicocele has an incidence of 40% in male sterility, causing oligozoospermia and asthenospermia. Patients first underwent non-invasive tests such as Doppler and echo-Doppler tests. According to the Authors experience, Doppler speedometry is decisive for the diagnosis of both idiopathic and subclinical varicocele, for the post-operative control of microsurgical anastomosis, and for the intra-operative detection of accessory spermatic veins. The surgical technique used by the Authors is the modified Palomo technique, but other techniques are investigated as well. Post-operative results, concerning both spermiogram and relapses are also evaluated.
