Trattamento simultaneo di metastasi epatiche e spleniche da carcinoma colo-rettale
Trattamento laparoscopico del Mielolipoma surrenalico: caso clinico e revisione della letteratura.
Adrenal myelolipoma is a rare benign, non-functioning tumor consisting of fat and hematopoietic tissues. In January 2005 we had observed an adrenal myelolipoma in 70 year old man. During the follow-up for bladder urothelioma, an abdominal CT revaled a well delineated 4x4 cm homogeneous fatty mass in the right suprarenal area with negative attenuation values. The functional study of adrenal gland was normal. The patient underwent videolaparoscopic right adrenalectomy (Gagner technique). Postoperative course was uneventful. The istological diagnosis showed adrenal myelolipoma. We conclude that videolaparoscopic adrenalectomy should be considered the gold standard treatment for benign adrenal …

Il trattamento chirurgico delle lesioni nodulari tiroidee: nostra esperienza. Analisi di 462 casi.
Nodular thyroid lesions are the most frequent endocrine diseases in the general population. The surgical procedure is indicated for nodular thyroid tissue degeneration, or when the suppressive pharmacologic therapy is less efficient, even if sometimes both factors are associated. In Authors' study 462 patients were observed who underwent surgical procedures for thyroid diseases between January 1997-April 2003. In the thyroid pathology, either uninodular or multinodular, the surgical therapy adopted is total thyroidectomy, according to other Authors. The aim of total thyroidectomy is to avoid recurrence and simplify long term pharmacologic treatment. Although the question about the surgical …
Primary malignant fibrous histiocytoma of the mesocolon transversum.
Primary malignant fibrous histiocytoma (MFH) is a rare and biologically aggressive tumor. Differential diagnosis must include cystic neoplasms of the pancreas (mucinous and serous cystoadenoma or cystocarcinoma), cystic lymphangioma or mesothelioma and retroperitoneal haematoma. Making the right diagnosis preoperatively may be often difficult, but MFH may be suspected when a huge retroperitoneal mass is found at imaging in elderly patients. We report a case of a primary abdominal MFH originating from the mesocolon transversum.

One shoot seldinger central venous catheterization in dialyzed patients
Introduction: Central Venous Catheterization is necessary in uremic patient (before dialysis) and many other conditions. In this study we demonstrated the advantages of ultrasonography to perform the procedure. Materials and methods: 48 uremic patient were submitted to ultrasound-guided central venous catheterization. The procedure was performed following the Seldinger “one shot” technique. Results: The mean operative time was 4 minutes, with a high rate of success (100%) and a low percentage of complications (2%). Conclusion: The ultrasound-guided central venous catheterization is a safe procedure, rapid and easy to perform. The procedure has a low rate of failures and complications and a …
An overview of a novel LC resonant device able to improve Power Quality in active and passive distribution networks
Nowadays power distribution systems are under a rapid evolution. The widespread penetration of distributed generation is bringing about new operating conflicts, which are adding to traditional power quality issues. The paper aims to analyse the performance of a new LC device able to improve power quality in electrical distribution systems, even in presence of distributed generation units. The different possible applications of the device are shown and the performances are proved by means of computer simulation. The first experimental results are also presented.

The role of colonscopy in patient follow-up after surgery for colorectal cancer
Applications of the Fault Decoupling Device to Improve the Operation of LV Distribution Networks
The aim of this paper is to present the operating principle of a new resonant device, called the fault decoupling device (FDD), able to improve power quality in electrical distribution systems. In low-voltage networks, this device can be employed in order to mitigate voltage dips due to faults or large induction motor startup. Moreover, in the presence of distributed-generation (DG) units, the FDD allows one to obtain various benefits such as a reduction of the fault current in each node of the network and an increase in the voltage at the DG unit node. In order to show the performances of the FDD, analytical studies and computer simulations were carried out which took into account various …
L'utilità della colonscopia nel follow-up dei pazienti operati per cancro del colon-retto. Analisi retrospettiva e revisione della letteratura

Analisi dei fattori di rischio dell'ipoparatiroidismo transitorio e definitivo nei pazienti sottoposti a tiroidectomia
Obiettivi. Con questa revisione della letteratura ci proponiamo di valutare quali sono i fattori che possono essere valutati nei pazienti da sottoporre a tiroidectomia ai fini di una migliore gestione preoperatoria e post-operatoria dell’ipoparatiroidismo transitorio e definitivo. Discussione. L’ipoparatiroidismo transitorio è una complicanza potenzialmente grave che include una vasta gamma di segni e sintomi che permane solo per poche settimane dopo l’intervento chirurgico. L’ipoparatiroidismo definitivo si verifica quando è necessario un trattamento medico per un periodo maggiore di 12 mesi. I fattori di rischio che ne possono influenzare l’insorgenza in seguito ad interventi di tiroidect…
Tiroidectomia in urgenza per linfoma primitivo della tiroide
Objective: A case of acute wheezing causing primitive thyroid lymphoma observed ay the Operative Unit of General and Thoracic Surgery of the University "P. Giaccone" of Palermo, Italy, is reported. Experimen tal design: Diagnostic, clinical and prognostic indication, evaluation of effectveness of radical surgical treatment and follow-up.

No relapse were recorded ad short follow-up. Conclusions: Total thyroidectomy in front of uncertain cytology with the suspect of Hashimoto's treatment or acute wheezing nr localized neopla…
A SIMPLE TECHINIQUE TO IMPROVE RESIDUAL SKIN PLASTICITY FOR SCROTAL RECONSTRUCTION IN FOURNIER'S GANGRENE
A 50 years-old man developed 24 hours after hemorrhoidectomy a severe Fournier's gangrene of the scrotum necessitating surgical exeresis of more than 2/3 of scrotal skin followed by hyperbaric oxygen therapy. After the resolution of the septic phase, scrotum reconstruction was obtained by tissue expansion to avoid more invasive advanced reconstructive techniques. The procedure consisted of an enzymatic and mechanical debridement and progressive skin expansion by package of gauzes of increasing volume covered with a collagenasecloramphenicol ointment (Iruxol®- Smith and Nephew, Italy), then closing the wound edges by temporary stitches to put under tension the skin. The reestablishment of th…
The value of diagnostic ultrasound for detecting occult inguinal hernia in patients with groin pain
Aims: chronic groin pain caused by an occult hernia can be a difficult clinical diagnosis and may require additional investiga- tive modalities. The aim of this study was to demonstrate the accuracy of ultrasound in diagnosing occult hernia in patients with recurrent inguinal pain and a negative clinical examination. Patients and methods: over a period of three years, a total of 76 patients were referred for ultrasound examination with clini- cally suspected occult inguinal hernia. Patients with positive US scans were offered surgery, while those with negative US findings were offered further imaging or other diagnostic tests. The ultrasound examination of the inguinal region was conducted …
