Extragonadal teratomas are rare tumors in neonates and infants and can sometimes show unusual, distinctive feature such as an unusual location, a clinical sometimes acute, presentation and a "fetiform" histotype of the lesion. We have extrapolated, from our entire experience of teratomas, 4 unusual cases, mostly operated as emergencies; 2 of them were treated just after birth. Aim of this paper is to report the clinical and pathological findings, to evaluate the surgical approach and the long-term biological behaviour in these cases, in the light of survival and current insights reported in the literature. ⋯ Some extragonadal teratomas of childhood of may rarely arise in the solid organs (liver, kidney), in the retroperitoneal space or the cranio-facial region, and also show unique histotype childhood characteristics ("fetiform") which distinguish them from more common cases. Being congenital tumours, prenatal diagnosis by US scan is extremely important in order to organize proper perinatal care in appropriate facilities where it is possible to define the diagnosis and carry out emergency surgery. An emergency procedure is frequently dictated both by complications related to the mass eddect and by the need to define the histology of the whole mass rather than just small biopsy specimens, Some teratomatas can hide more or less extensive islands of immaturity signs of malignant transformation that are clinically evident. It should be remembered that high serum levels of alpha-fetoprotein and calcficationof the imaging study, that are usually pathognomonic elements for fiagnosis, nay be lacking in abdominal lesions. Moreover, some additional specific diagnostic problems can be faced by either the radiologist (differential diagnosis from acquired or congenital cystic lesions, identification of the primary site of origin in the liver kidney or retroperitoneal space). Or the histopathologist (exclusion of renal metastasis of a primary gonadal teratomas of a glomerular and tubular differentiation a Wilm's tumour). The prognosis is generally benign, although the AIEOP guideline pointed out that high levels of circulating markers, including AFP, in children affected by mature or immature teratomas, could indicate rhe presence of micro-foci of YST, marking them out as at high risk. The UKCCSG II and the SFOP indicates AFP values exceeding 10,000 ng/ml as the threshold identifying a group of patients with a severe prognosis. The treatment indicated is early, complete exeresis, followed by a careful, exstensive, microscopic examination, associated, if necessary, with adjuvant chemotherapy. Finally, to improve the prognosis, close, long-term clinical, laboratory and imaging surveillance is necessary, at shorter intervals during the first 5 years after the exeresis and annually thereafter.

Small bowel perforation from blunt abdominal trauma is a common injury. Isolated perforation of the small bowel after blunt abdominal trauma is infrequent and the diagnosis can be elusive. A case of isolated perforation from blunt trauma is presented. ⋯ Early surgical intervention leads to good recovery. Sufficient vigilance and suspicions of small bowel perforation should always be considered after blunt trauma even when symptoms and physical findings are minimal. Diagnostic difficulties result in delayed surgical treatment and eventually in increased morbidity and mortality.

Comparative Study Clinical Trial
The use of haemostatic agents in thyroid surgery: efficacy and further advantages. Collagen-Fibrinogen-Thrombin Patch (CFTP) versus Cellulose Gauze.
To assess the efficacy of two widely used topical haemostatic agents: oxidised regenerated cellulose gauze and Collagen- Fibrinogen-Thrombin Patch in patients undergoing total thyroidectomy. ⋯ Both haemostatic agents reduced the amount of sero-hematic fluid during the first 24 hours post-surgery, with CFTP more effective than oxidized cellulose gauze. The use of haemostatic agents may increase the quality of thyroid surgery, improve patient comfort after surgery, and reduce hospital stay.

The prognosis of locally advanced Gastric Cancer following surgical therapy alone is poor. Peritoneum represents a preferential site of dissemination in such neoplasm. Hyperthermic intraperitoneal chemotherapy (HIPEC) has been used in association with cytoreductive surgery (CRS) in the treatment of GC peritoneal carcinomatosis (PC). Aim of our preliminary experience is reporting our data on prophylactic HIPEC (P-HIPEC) in patients with GC at high risk of developing PC. ⋯ Peritoneal dissemination appears to be a strong determinant in defining GC patients prognosis. Even after curative resection, peritoneal recurrence develops in about 60% of the patients with T3 and T4 tumors, and up to 40% of resected gastric cancer patients die as a direct result of peritoneal dissemination. Clinical trials showed that surgery plus HIPEC was associated with a significant improvement in survival compared to surgery alone in patients affected of GC with resectable PC. At present day there are not studies evaluating the role of P-HIPEC in patients at high risk of developing PC. The rationale of P-HIPEC is based on the concept that positive peritoneal lavage is considered an M1 (stage IV) similarly to macroscopic PC by the 7th TNM classification. Also analogous is the median survival of this 2 groups of patients. Detection of peritoneal micrometastases with cytologic examination has been considered a major method to predict peritoneal recurrences; the sensitivity of this assay is low. Recently, molecular approaches using real-time reverse-transcriptase polymerase chain reaction (RT-PCR) technique has made possible the increase in the sensitivity. We can conclude, although the preliminary experience, that prophylactic HIPEC in locally advanced gastric cancer is feasible, increasing median survival compared to surgery alone. For sure this procedure need to be performed in the highly specialized centres strongly respecting the eligibility criteria.

Vocal cord injuries (VI), postoperative hoarseness (PH), dysphonia (DN), dysphagia (DG) and sore throat (ST) are common complications after general anesthesia; there is actually a lack of consensus to support the proper timing for post-operative laryngoscopy that is reliable to support the diagnosis of laryngeal or vocal fold lesions after surgery and there are no valid studies about the entity of laryngeal trauma in oro-tracheal intubation. Aim of our study is to evaluate the statistical relation between anatomic, anesthesiological and surgical variables in the case of PH, DG or impaired voice register. ⋯ Direct laryngoscopy is essential for the detection of arytenoid lesions after orotracheal intubation for general anesthesia. In our opinion, a part of temporary post-operative DN or PH is due to monolateral or bilateral arytenoids oedema, secondary to prolonged or difficult orotracheal intubation, valuable with laryngoscopy 72 hours after surgery. Is necessary to adjunct these complications in the surgical informed consensus scheme.
