The fear of being laughed at brings to the fore the problematic side of an otherwise very positive aspect of human experience. In the streamline of investigations analyzing the presence and characteristics of gelotophobia, a study focusing on psychiatric patients was carried out. The diagnoses were established according to the criteria of the DSM IV TR (American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders (DSM), APA, 2000). Based both on clinical and empirical observations, the main hypothesis advanced was that using the Geloph15 scale, Ss with a psychiatric diagnosis would have higher mean scores than Normal Controls. An additional hypothesis was that intragroup differences were also expected among the various diagnostic categories. The main hypothesis was amply supported, and explanatory suggestions of the finding were proposed. Intragroup differences proved also to be significant. Patients with personality disorders and patients with schizophrenic disorders scored higher than Normal Controls and the other diagnostic groups. And also the number of years spent in psychiatric care resulted significantly associated with higher gelotophobia mean scores. From the present study, a circular, interactive relationship was confirmed between laughter and mental health, which can alternatively be highly positive or deeply negative

Background: After trauma or surgery, researchers have suggested that medium-chain triglycerides have metabolic advantages, although they are toxic in large doses. To try to reduce this potential toxicity, structured lipids, which provide a higher oxidation rate, faster clearance from blood, improved nitrogen balance, and less accumulation in the reticuloendothelial system, could be used. Therefore, we evaluated, through a blind randomized study, the safety, tolerance, and efficacy of structured triglycerides, compared with long-chain triglycerides (LCT), in patients undergoing colorectal surgery. Methods: Nineteen patients were randomized to receive long-chain or structured triglycerides as a lipid source. They received the same amount of calories (27.2/kg/d), glucose (4 g/kg/d), protein (0.2 g/kg/d), and lipids (11.2 kcal/kg/d). Patients were evaluated during and after the treatment for clinical and laboratory variables, daily and cumulative nitrogen balance, urinary excretion of 3-methylhistidine, and urinary 3- methylhistidine/creatinine ratio. Results: No adverse effect that required the interruption of the treatment was observed. Triglyceride levels and clinical and laboratory variables were similar in the two groups. A predominantly positive nitrogen balance was observed from day 2 until day 5 in the LCT group and from day 1 until day 4 in the structured triglycerides group. The cumulative nitrogen balance (in grams) for days 1 to 3 was 9.7 ± 5.2 in the experimental group and 4.4 ± 11.8 in the control group (p = .2). For days 1 to 5 it was 10.7 ± 10.5 and 6.5 ± 17.9 (p = .05), respectively. The excretion of 3-methylhistidine was higher in the control group but decreased in the following days and was similar to the experimental group on day 5. Conclusions: This study represents the first report in which structured triglycerides are administered in postoperative patients to evaluate safety, tolerance, and efficacy. It suggests that Fe73403 is safe, well tolerate

Risk of local recurrence of rectal cancer remains high despite extensive therapeutic strategies, many of which have been tried to achieve better local control (i.e., external beam radiation therapy (EBRT)). Recently, intraoperative radiation therapy (IORT) has been introduced in clinical protocols to boost the areas at risk of local recurrence.

PURPOSE: Best chances of a cure from colorectal cancer are obtained before metastatic spread. Lack of specific tests allowing early diagnosis of the tumor accounts for investigation of gene alterations involved in carcinogenesis by a noninvasive method. In the present study, K-ras codons 12 and 13 mutations were studied in neoplastic cells shed from the bowel into the stool and those contained in the tumor and normal mucosa. Moreover, healthy patients and a few others with precancerous conditions were examined. METHODS: Stool, tumor, and mucosa samples were taken from 25 patients with colorectal adenocarcinoma. Stool and mucosa samples were obtained from 11 healthy patients, and stool, pathologic bowel tissue, and normal mucosa samples were obtained from 3 patients with adenoma (1) or ulcerative colitis (2). Polymerase chain reaction amplification and restriction enzyme analysis were performed. RESULTS: K-ras codon 12 mutations were detected in both tumor and stool samples of 10 cancer patients, and no gene alterations were observed in 14 patients. In one patient with a tumor, a mutation was shown in only the tumor tissue. The agreement rate in tumor and stool analysis was 96 percent. A normal pattern of K-ras codons 12 and 13 was observed in the bowel mucosa. All stool and mucosa samples from healthy patients were not altered in K-ras. Agreement was registered between samples taken from patients with preneoplastic lesions. CONCLUSIONS: These preliminary findings show a high rate of accuracy in the investigation of K-ras alterations in the colorectal cells shed into the feces, suggesting that such an approach could be used to study other gene alterations and, prospectively, to identify early colorectal cancers.

34 patients with locally advanced (T4) or recurrent rectal cancer have been treated with: 1. external beam radiotherapy (45-48 Gy) + 5FU(1000 mg/m2/daily iv continuous infusion day 1-4) + MMC (10 mg/m2/daily iv, day 1); 2. surgical resection (if feasible) + IORT (10-15 Gy); 3. adjuvant chemotherapy (5FU+leucovorin, 6-8 cycles). Grade 3 acute hematological toxicity was observed in 1 case only. 23 of 34 patients underwent radical surgery. Perioperative mortality and morbidity was 0% and 17% respectively. In the 23 operated patients with a mean follow-up of 18.6 months there were 2 local recurrences, 5 blood metastases, (1 death of disease). 16 patients were shown to be NED (3-36 months).

Mature cystic teratoma is the most common type of mediastinal germ cell neoplasm. It usually becomes clinically apparent in early adult life. Preoperative evaluation generally includes computerized axial tomography (CT scan) in addition to PA and lateral chest roentgenograms. These procedures are diagnostic in a high percent of patients. Anterior-superior mediastinal tumors are easily removed through a midline sternotomy incision. This well-tolerated incision provides full access to the anterior-superior mediastinum and permits assessment of the relationship of the tumor to adjacent structures. The authors report their one-case experience and describe the histopathological and clinical aspects of this pathology and underline that a correct diagnostic procedure is helpful for correct surgical treatment.

Lymph node involvement in colorectal cancer, one of the most important prognostic factors, can be sometimes underestimated. In this study the authors report the results of two different techniques of specimen preparation and examination. In 240 patients (Group I), histologic examination was performed using a conventional procedure. In Group II (60 cases) the resected bowel and its mesentery were separately stretched, pinned on to a cork board, and fixed. The mesentery was divided according to node location (intermediate and principal) and evaluated by sight and palpation to identify lymph nodes. The bowel segment was divided from 5 cm proximally to 5 cm distally to the tumor every 10 mm in serial 3 mm slices. Three and 10 mm slices were then carefully examined by sight and palpation. Isolated lymph nodes embedded in groups (10-12 per paraffin block) were stained and investigated for neoplastic involvement. The specimen examination procedure used in Group II resulted in identification of a higher number of lymph nodes (mean = 41.1) and nodal metastases (mean = 10) compared to the standard technique used in Group I (mean = 11.3 and 2.4, respectively--P < .05). The percentage of N+ cases also was increased in Group II (48.3%) when compared to that in Group I (30.4%; P < .05). The new technique is simple, inexpensive, and efficacious for the detection of lymphatic metastases in colorectal cancer.
