A total of 2013 individuals from 4 families, were caught between May 2006 and December 2010. Female: male sex ratio varied from 1:0.3 in Trachurus mediterraneus ponticus to 1:1.9 in Sarda sarda. According to the age readings, distribution varied from I to VI year. The von Bertalanffy equation and growth performance index were determined by FiSAT II software in Alosa imaculata, Engraulis encrasicolus, Trachurus mediterraneus ponticus and Sarda sarda. Asymptotic values for total length (L∞) ranged from 82.97 cm for S. sarda to 14.60 cm for E. encrasicolus. Growth rates (k) varied from 0.4794 year−1 for E. encrasicolus to 0.1044 year−1 for T. mediterraneus. The data sets were limited in most cases, thus this study provides preliminary population parameters only, but for species for which information is scarce.

The peritoneal reflection is an important landmark in intraluminal surgery, rectal trauma, impalement, and rectal adenocarcinoma. Objectives To investigate the correlation between the lengths of the middle rectal valve and of the peritoneal reflection determined with rigid sigmoidoscopy and to determine whether there are any differences in the location of the peritoneal reflection between the genders and in relation to body mass index (BMI) and parity. Design We prospectively investigated the location of the middle rectal valve and of the peritoneal reflection via intraoperative rigid sigmoidoscopy in colorectal cancer patients undergoing elective colorectal surgery. Results We evaluated 38 patients with a mean age of 55.5 years old (57.5% males) who underwent colorectal surgery at the coloproctology service of the Hospital Santa Marcelina, São Paulo, state of São Paulo, Brazil. There was substantial agreement between the lengths of the middle rectal valve and of the peritoneal reflection (Kappa ¼ 0.66). In addition, the peritoneal reflection was significantly lower in overweight patients (p ¼ 0.013 for women and p < 0.005 for men) and in women with > 2 vaginal deliveries (p ¼ 0.009), but there was no significant difference in the length of the peritoneal reflection between genders (p ¼ 0.32). Conclusion There was substantial agreement between the lengths of the peritoneal reflection and of the middle rectal valve, and the peritoneal reflection was significantly lower in overweight patients and in women with more than two vaginal deliveries.

Objective-To analyze C-reactive protein level on the third postoperative day of an elective colorectal surgery and compare the marks between reoperated and non-reoperated patients and to establish a cutoff value to predict or avoid surgical reoperations. Methods-Retrospective study based on the analysis of electronic charts of over 18-year-old patients who underwent an elective colorectal surgery with primary anastomoses during the period from January 2019 to May 2021 by the proctology team of Santa Marcelina Hospital Department of General Surgery with C-reactive protein (CRP) dosage taken on the third postoperative day. Results-We assessed 128 patients with a mean age of 59.22 years old and need of reoperation of 20.3% of patients, half of these due to dehiscence of colorectal anastomosis. Comparing CRP rates on the third postoperative day between non-reoperated and reoperated patients, it was noted that in the former group the average was of 153.8±76.2 mg/dL, whereas in reoperated patients it was 198.7±77.4 mg/dL (P<0.0001) and the best CRP cutoff value to predict or investigate reoperation risk was 184.8 mg/L with an accuracy of 68% and negative predictive value of 87.6%. Conclusion-CRP levels assessed on the third postoperative day of elective colorectal surgery were higher in patients who were reoperated and the cutoff value for intra-abdominal complication of 184.8mg/L presented a high negative predictive value.

Chronic constipation can have a different etiology in patients who underwent a cesarean section and result from postoperative stress and metabolic response to trauma, analgesic agents, immobilization, and dietary restrictions. Chronic constipation may also occur due to puerperium-related psychological changes and to the stretching and weakening of the perineal and abdominal muscles after childbirth. Objectives The present study analyzes intestinal transit restoration after a cesarean section and the influence of osmotic laxative agents. Methods The present prospective, nonrandomized sample study used the ROME III questionnaire and the Bristol stool scale in adult women who underwent a cesarean section. We divided the subjects into 2 groups, each with 30 patients, to compare the effect of the prophylactic administration of an osmotic laxative. Results We evaluated 60 randomly-chosen pregnant wome...

Objectives To identify risk management tools already used and implemented in a reference teaching hospital in the city of São Paulo and to analyze their application and risk factors in medium and large colorectal surgery. Method Observational, longitudinal, and prospective study, with 30 patients with colorectal disease hospitalized in the surgical ward of the coloproctology service and in need of surgical treatment. In the first group, the protocol was applied with the knowledge of the researcher only, and, in the second group, with the knowledge of both the researcher and the attending physicians. Results Sixty percent of the patients were female with a mean age of 60.93 years and body mass index (BMI) of 26.07 Kg/m2.After surgery, patients in the first group who did not receive veno...

AIM: The aim of this study was to analyze epidemiological data, medications in use, previous surgeries, and hospitalizations in patients with inflammatory bowel diseases, and to determine the impairment in QoL of these patients. METHODS: This is a prospective, cross-sectional, observational study in patients with inflammatory bowel disease followed up in a tertiary hospital in São Paulo-SP, Brazil. General and disease-related, evolution, and quality-of-life data were analyzed using a validated quality-of-life questionnaire, namely, Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS: Fifty-six individuals were evaluated, with an equal number of patients with Crohn’s disease and ulcerative colitis. ...

It is difficult to make their diagnosis before biopsy, surgical resection or necropsy. A recent publication described only 94 cases of these tumors. There is no sex predilection and apparently it has no association with cirrhosis or preexisting hepatic disease. The most effective treatment is hepatectomy, and resection is determined by size and location of the lesions.
