- Induced pneumoperitoneum in CT evaluation of peritoneal carcinomatosisPublication . Caseiro-Alves, F; Gonçalo, Manuela; Abraúl, E; Pinto, E; Oliveira, CF; Vilaça-Ramos, HBACKGROUND: Imaging of peritoneal carcinomatosis is a well-known problem even for technologies as recent as computed tomography (CT). The purpose of this study was to evaluate whether CT performed after induced pneumoperitoneum (CT-PP) could have a higher sensitivity in the detection of peritoneal implants over conventional CT. METHODS: Five patients with known ovarian malignancies underwent standard CT and CT-PP. Exploratory laparotomy was performed with a maximum interval of 7 days from the last imaging procedure. Results were prospectively compared with surgical findings on a compartment to compartment basis. RESULTS: CT-PP was well-tolerated with no serious adverse reactions registered. The anterior and visceral peritoneum, the paracolic gutters and subphrenic areas were particularly well depicted but not the pelvis which was poorly evaluated in all cases. CT-PP detected all the three cases where peritoneal carcinomatosis was present even when metastatic nodules were smaller than 2 mm; it also showed intraabdominal adhesions in two patients, an important finding that precludes the use of intraperitoneal chemotherapy. CONCLUSIONS: With CT-PP there seems to be a reduction in the threshold of detectability of peritoneal implants. The direct demonstration of intraperitoneal adhesions is an important secondary finding. Disadvantages of CT-PP are (1) it is a time-consuming method and (2) it does not evaluate all the peritoneal recesses potentially involved in peritoneal carcinomatosis.

- Placental site trophoblastic tumour: the value of transvaginal colour and pulsed Doppler sonography (TV-CDS) in its diagnosis: case reportPublication . Bettencourt, E; Pinto, E; Abraúl, E; Dinis, M; Oliveira, CFThe clinical, transvaginal sonography and colour flow mapping of one patient with placental site trophoblastic tumour is presented. Colour Doppler documented a marked increase in uterine vascularity, characterised by low diastolic flow suggestive of low resistance blood flow, without regression after completion of apparently successful chemotherapy, when negative beta-hCG plasma levels were obtained. Surgical treatment was based upon our experience with colour Doppler assessment of gestational trophoblastic tumours and a review of the literature. This case suggests that TV-CDS, performed serially, is very useful in monitoring patients during chemotherapy and in detecting residual tumour, and should greatly increase the accurancy of diagnosis of PSTT.
- Serologic profile of some sexually transmitted diseases in women with squamous intraepithelial lesionsPublication . Gomes, C; Dias, MF; Falcão, F; Oliveira, CFThe purpose of this study consisted of the evaluation of some sexually transmitted diseases in patients with cervical pathology, namely squamous intraepithelial lesions. METHODS: a prospective study was performed. Patients with an abnormal cervical smear were submitted to colposcopy, directed biopsy and an immunologic assay for Chlamydia, Herpes Simplex Virus (HSV) types 1 and 2, Cytomegalovirus, Treponema pallidum, Hepatitis B and Human Immunodeficiency Virus I and II. The same parameters were evaluated in women with normal cervical cytology in a matched control group. A comparative study was performed evaluating some epidemiological parameters and the referred immunologic assays. RESULTS: 118 patients were separated into four groups. Statistically significant differences were observed in the personal history of fungi infections, as well as Chlamydia and HSV 2 IgM. CONCLUSION: immunologic assays may prove useful in identifying sexually-transmitted diseases, especially Chlamydia and HSV 2 infections, in Human Papillomavirus infected women.

- How to organize gynecologic oncology in the future: Results of an international questionnairePublication . Vergote, IB; Oliveira, CF; Dargent, DA questionnaire was sent to 93 gynecologic oncologists from 54 countriesabout the way in which gynecologic oncology was organized in their country, orif the (sub)speciality wasnot yet recognized, how they thought it should be organized. The questionnairewas answered by 64 persons from 42 different countries. The subspecialty wasrecognised in 17 (41%) of the countries. Fifty-five respondents (86%) thought thatgynecologic oncology should be a subspecialty of obstetrics and gynecology. Themedian duration of the gynecologiconcologic fellowship program was 30 months. Diagnosis and surgery accounted forabout 58% of the duration of the program. In 52% of the answersfrom countries with boardcertification, the fellows had to pass a theoretical and practical examination,and in addition 22% of the candidates had to defend a thesis to qualifyfor certification.Training centers in countries that recognized gynecologic oncology had amedian number of 142 new cases per year (for 1 fellow). The median number ofgynecologic oncologogistsand fellows per 10(7) inhabitants in countries with boardcertification in gynecologic oncology was 42 and 6, respectively. Finally, theimportant role of internationalsocieties (like the International Gynecologic Cancer Society and the EuropeanSociety of Gynaecological Oncology) in supporting the countries withoutrecognized GynecologicOncology was stressed by the respondents. The setting up of internationalstandards for training programs, training centers, board certification, and theorganization ofinternational exchange programs for fellows seemed to be equally important,according to the questionnaire responses.
