[Evaluation of postoperative mucosa and skin temperature after surgery for impacted third molar].

Surgery for impacted third molar is often characterized, in the postoperative period, by pain, trismus and swelling. The study evaluates temperature variations of mucosa and skin after application of ice packs, in three different modalities, to the region overlying the surgical site. The goal was to identify any correlation between variations of temperature and postoperative clinical symptoms. For this purpose we selected 54 patients programmed for impacted third molar surgery. The patients were divided into three groups of 18. Time and frequency of application of the ice pack varied in the three groups; 5'/30' (group 1); 10'/60' (group 2); 20'/60' (group 3). During the four hours following surgery, temperatures of mucosa and of skin at the surgical site were measured with high-precision thermocouples, maximum response 5". The results indicate that application of an ice pack for 5'/30' or for 10'/60' controls the temperature of the mucosa post-surgery more effectively, and that the duration of surgery appears not to influence temperature variations. In the postoperative phase we recommend a rational application of ice packs appropriate to the constitution of each patient.

[CT-guided FNA in the diagnosis of lung opacities. Our experience].

Between January 1989 and December 1994 we accomplished 130 CT-guided transthoracic fine needle aspirations (FNA) in 120 patients. Ten patients underwent a second FNA because of the negativity and doubts of the first. Diagnosis was targeted in 114 (95%) patients and 89% showed cytological evidence of malignancy. FNA-CT guided is reliable in the diagnosis of lung cancer, but less accurate in excluding diagnosis of malignancy. In our experience FNA had an accuracy with regard to lung cancer, of 92%. Sensitivity and specificity were respectively 93.8% and 100%. There were 6 false negative and 9 very negative. All patients should have bronchoscopy rather than FNA as the initial diagnostic procedure and perform it only in the absence of endobronchial lesions and malignant cells obtained with cytologic sputum or fiber bronchoscopy. In our experience 91 patients have lung cancer and thoracotomy was performed in 21% with confirm of diagnosis. FNA offers several advantages over other diagnostic procedures used in the evaluation of patients with intra-thoracic nodules and masses. The uses of small needles (20-22 gauge) and CT-guide has practically eliminated the risk of major haemorrhage. Deep and superficial lesions of the lung may be approached safely with FNA-CT guided and complications are no fatalities. Pneumothorax occurred in our experience in 5 cases and no occurred a chest drainage.

[A carcinoid with cecal localization. Apropos a case].

An observed case of carcinoid tumor of the large-bowel in a 68-year-old woman leads to an analysis of the clinical-diagnostic and therapeutic aspects of this rare gastrointestinal tumour. Carcinoid tumour represents 0.8-1.5% of malignant digestive tumours, in 6% of cases it is localized in large-bowel and in 2-3% in cecal-bowel. In our experience there is no specific symptoms and diagnosis was based on postoperative histopathologic analysis. Right hemicolectomy with lymphadenectomy performed and the operative specimen included a 7 cm diameter tumour, which had narrowed the lumen by 80% and infiltrated ileocecal valve. Carcinoid tumour presents considerable problems of diagnosis because symptoms are aspecific. Diagnosis is possible only in patients with high urinary levels of 5-HIAA, in presence of carcinoid syndrome and by endoscopic biopsy when tumour infiltrated gastrointestinal mucosa. False negative cases are frequent in small carcinoids ( < 2 cm) because the tumour tissues are covered by integral mucosa. C.T., ultrasonography and angiography play a primary role in the diagnosis of this tumour but octreotide scintigraphy is very important for tumour and metastases localization in consequence of its ability to demonstrate somatostatin receptor positive tumours. Radical surgery is the only treatment in very little carcinoids to prevent metastases risk. Determinant risk factors are: primary size, localization, serosal penetration. In patients with any of these risk factors, resection with regional lymphadenectomy is recommended. Other prognostic factors include histologic differentiation, the presence of macroscopic residual disease after initial surgery and level of 5-HIAA in urine. We think that neither adjuvant chemotherapy, or radiotherapy may play a significant role in this neoplasm. Many authors report considerable unsuccessful with this treatment and it is used mainly for palliation. At present, the medical treatment of inoperable gastrointestinal carcinoid consist in association with interferon alpha and octreotide. During this treatment the size of the tumour is stable: reduction of symptoms and 5-HIAA urinary levels are noted.
