RESUMO
The aim of the present study was to validate low dose Multislice Spiral Computed Tomography (MSCT) in the diagnosis of breast lesions. Fourteen patients with mammographic and ultrasound findings suspect of malignant neoplasm underwent dynamic MSCT of the breast under basal conditions and 1, 3, and 6 minutes after intravenous injection of iodinated contrast medium. Both enhancement of the lesion >100% without further increase after 6 minutes, and irregular margins of the lesion were considered signs of malignancy. All lesions were examined cytologically and/or histologically. A correct diagnosis was achieved by MSCT in 7/8 malignant lesions, and in 6/6 benign lesions. The only malignant lesion missed by MSCT was histologically a ductal carcinoma in situ (false negative). In one case the MSCT showed the multifocality of an infiltrating ductal carcinoma, and in another it defined the bilaterality of the malignant lesions. Sensitivity and specificity of MSCT in the diagnosis of malignancy of a lesion were 88% and 100%, respectively. Our results suggest that MSCT is an effective diagnostic method to define suspicious breast lesions, and a valid alternative to Magnetic Resonance Imaging, especially when the latter is not feasible.

Primary sclerosing cholangitis (PSC) is an idiopathic chronic inflammatory condition affecting intra- and extra-hepatic biliary system. The aim of this study is to stress the importance of cholecystectomy in patients with PSC. Consideration should be given to performing a cholecystectomy in PSC patients with gallbladder adenomyomas or calculi, even asymptomatic; this happens in approximately 15% of cases.

Parotid tumours represent a wide group of tumours which are mostly localized in the major salivary glands. We report a case of a 69-year old female with a parotid tumour history who was referred to us with a prominent lump and swelling localized in the right parotid area. In the period between 1985-2002, she was operated 5 times elsewhere for a recurrent pleomorphic adenoma of the right parotid (mixed tumour until 1991), which was histologically confirmed. Sixteen years after the primitive tumour, she underwent mastectomy and axillary dissection for a ductal carcinoma. Routine follow-up has been conducted on both malignancies. Pleomorphic adenoma is the most frequent tumour of the parotid. The potential risk of a malignant transformation can increase over the years with an incidence of 1% to 7%. Management of these recurrences is complex and controversial because of the different treatment options advocated such as radical resection with possible facial nerve sacrifice, or postoperative radiotherapy in non radical cases.

Cystic lymphangioma is a benign tumor of uncertain etiology characterized by a slow growth; in 2-8% of cases it is localized in the mesentery. Symptomatology is aspecific and preoperative diagnosis is often difficult. The Authors report the case of a mesenteric cystic lymphangioma in a patient who had undergone subtotal colectomy eight years earlier for an adenocarcinoma occluding the sigmoid colon. The patient was hospitalized for intestinal occlusion.

Bile duct carcinomas are known to be difficult to cure, due to frequent locoregional recurrence even after radical resection. The Authors analyze their experience in a study about 53 patients treated between October 1991-January 2002.

The literature considers hyperthermic intraoperative intraperitoneal chemotherapy a safe and effective procedure for peritoneal carcinomatosis, but a technical improvement is necessary. Regional chemotherapy anticipates the "downfall" of tumoral cells in the peritoneum. The Authors considered 5 patients--female, age 27-45 years, ASA 2--operated of peritonectomy in ovaric neoplasia with peritoneal metastasis. The hyperthermic intraoperative intraperitoneal chemotherapy has been made at the end of the surgery with a hot solution (43 degrees C): 3000 ml of dextrose 1.5% with mytomicina C 25 mg e cysplatino 75 mg/m2. We considered variation of emodinamic parametres (blood pressure, central venous pressure, stroke volume, etc.) and biochemical parametres (Na, K, CI-, CO2, etc.). These parametres have been correlated with some complications: fistula, anastomotic leakage, pancreatitis and postoperative bleeding.

Appendiceal calculi are found in a limited percentage of patients. They are in association to an elevated prevalence of necrotic appendicitis and perforation of the appendix. The Authors report a case of acute appendicitis associated to appendiceal lithiasis with perforation of the organ. They emphasize the possibility to perform a preventive appendectomy in case of incidental appendiceal lithiasis. Besides they consider the differential diagnosis of the calcified images located in the lower abdominal quadrants with the aid of the various imaging methods available today, particularity sonography and computerized tomography.

Most cases of total spinal block have been reported in the literature. The displacement of the catheter and the consequent dural perforation are the causes in large percentage of the patients (75%). The Authors describe this case for the importance of the causes and outcome of the patient. A 48 years old woman presented for hysterectomy for uterine fibromas. After having individualized the L3-L4 interspace, a test dose of 3 ml carbocaine 2% was injected. After that, the spinal block was obtained using ropivacaine 0.75% (total dose = 10 ml) injecting slowly, in following times, 5+5 ml of anaesthetic solution. The patient, perfectly conscious at first, presented a gradual increase of the difficulty in talking and breathing. Subsequently she showed a complete paralysis with loss of the consciousness, respiratory arrest, bilateral and symmetrical midriasis, as well as total areflexia. Endotracheal tube was placed. After eighty minutes from the end of the administration of the local anesthetic, spontaneous thoracic excursions appeared, even though of moderate ampleness, midriasis reduced. The patient recovered consciousness and sufficiently ventilated; therefore the endotracheal tube was removed.

The association between chemotherapy and hypertermia produces a synergic effect. In this study the Authors present their experience, by the analysis of the results. From 1993 to 2000, 17 patients have been treated with surgery associated with hypertermic chemotherapy for peritoneal carcinomatosis. For the management of these patients a constant cooperation among surgeon, cardiologist and anaesthetist is very important.
