Is avoidance of surgery possible in patients with perimenopausal ovarian tumors using transvaginal ultrasound and duplex color Doppler sonography?

A total of 108 cases of small perimenopausal ovarian tumors (largest diameter, less than 7 cm) were evaluated by transvaginal sonography and duplex color Doppler sonography; 101 had criteria for benignity and 7 for malignancy. All cysts were punctured and aspirated to avoid unnecessary surgery (benign cases) and establish the cytologic diagnosis as well as to avoid the risk of leakage (malignant cases). Recurrence rate of benign punctured cysts was 25% within 1 year of follow up. No difference in recurrent rate was seen between pre- and postmenopausal patients (19 of 56 cases in the premenopausal group, and five of 28 cases in the postmenopausal group). The larger the cyst, the greater the risk of recurrence. Puncture and aspiration of seven sonographically established malignant tumors allowed cytologic diagnosis before surgery, and no evidence of leakage was noted at the time of surgery. No significant differences were observed between cytologic and histopathologic findings in cases that went to surgery. Puncture and aspiration of small endometriomas (17 cases) was found to be inefficient for therapeutic purposes. Finally, owing to the high percentage of unsatisfactory cytologic results (20%) with cyst aspiration, vaginal and color Doppler sonography seemed more efficient in distinguishing between benignity and malignancy.

[Abdominal, perineal and vaginal sonographic diagnosis of cervix insufficiency].

In patients with cervical incompetence, the diagnostic efficiency of abdominal, perineal and vaginal sonography was compared. 73 patients, who were divided into three groups, were examined: Group A (n = 50) control group, Group B (n = 11) normal pregnancies, Group C (n = 12) pregnancies with demonstrated cervical incompetence. According to our results, using vaginal sonography, only the incompetent pregnancies showed significant shortening of the cervical length. Characteristic scans were also obtained (membrane herniation) which were useful in diagnosis and control in the performance of cerclage.

[Hysterosalpingography: synechiae? Gartner's ducts?].

A linear shadow parallel to the uterus longitudinal axis, was observed in a hysterosalpingography (HSG) and has set up a controversy between synechiae and Gartner's ducts, without reaching a definitive conclusion. A case like this does not seem to have been published previously.

[Efficacy of a new microencapsulated pancreatin versus a conventional preparation, in the treatment of steatorrhea of pancreatic origin].

Malabsorption of pancreatic origin has been traditionally treated with pancreatic enzymes, but the effectiveness of treatment has been limited, related to the scant enzymatic activity of preparations, enzyme lability to acid attack and deficient mixing with the intestinal bolus, among other factors. We studied the efficacy of a new pancreatic enzyme preparation in the form of pellets, which mix easily with the intestinal bolus, are protected against gastric acid attack and have a high lipase concentration (Creon, Kalichemie-Pharma), as compared to traditional unprotected pancreatin in the form of tablets (Pankreon 700). The study was open, comparative and crossover, and included 12 patients. The diagnosis was chronic alcoholic pancreatitis in 10 cases and idiopathic pancreatitis in 2, with a steatorrhea of more than 10 g/24 h and a basal gastric pH less than 2.5. The duration of treatment was 3 weeks, using a diet containing 100 g of fat. The first week served as a control, and in the 2nd and 3rd treatment was given in the form of 7 capsules of Creon (2.1 g pancreatin and 70,000 UFIP lipase) or 17 tablets of Pankreon 700 (11.9 g pancreatin and 476,000 UFIP lipase) by randomized assignment. Our results confirm the beneficial effects observed by others. Steatorrhea was significantly reduced, up to 45.6% with Pankreon 700 and 57% with Creon, in spite of a dose that had 6.8 times less lipase activity, 5.6 times less pancreatin weight and 2.4 times fewer units ingested (capsules/tablets). Patients showed significant weight gain. At 30 days of treatment with Creon, steatorrhea had declined 70% and the weight gain was significant.(ABSTRACT TRUNCATED AT 250 WORDS)
