    The purpose of the present study was to evaluate some epidemiological, clinical and pathological characteristics of the different grades of vulvar intraepithelial neoplasia (VIN), and its relation with the presence of human papillomavirus (HPV). The charts of 46 women with VIN, examined from 1986 through 1997, were reviewed. For statistical analysis the chi² with yates correction when appropriate, and Fisher’s exact tests were used. Regarding the grade of VIN, six women presented VIN 1, six others had VIN 2 and the remaining 34 presented VIN 3. All women presented similar characteristics such as age, menstrual status and age at first sexual intercourse. Women with more than one lifetime sexual partner had a tendency to show more VIN 3 (p = 0.090). Cigarette smoking was significantly associated with the severity of the vulvar lesion (p = 0.031). HPV was significantly more frequent in women younger than 35 years of age (p = 0.005) and in women with multiple lesions (p = 0.089). Although the number of lesions were not related to the severity of VIN (p = 0.703), lesions with extensions greater than 2 cm were significantly associated with VIN 3 (p = 0.009). The treatment of choice for VIN 3 was surgery, including local resection and simple vulvectomy. Eight women relapsed, and only one had VIN 2. We concluded that among women with VIN, cigarette smoking and more than one lifetime sexual partner were associated with high-grade lesions. HPV was more frequent among patients younger than 35 years of age presenting multiple lesions. Women with VIN 3 presented lesions bigger than 2 cm and a high relapse rate, despite the type of treatment applied.

    Estimation of Fetal Weight: Comparison Between a Clinical Method and Ultrasonography

    Purpose: to assess the validity of fetal weight estimation by a method based on uterine height — Johnson’s rule. Methods: one hundred and one pregnant women and their newborn children were studied. The fetal weight was estimated using an adaptation of Johnson’s rule, which consists of the clinical application of a mathematical model to calculate the fetal weight based on the uterine height and the height of fetal presentation. The estimated weight was obtained on the day of delivery and was compared to the weight observed after birth. This, in turn, was the control of the analysis of validity of the method used. On the same date, a detailed obstetrical ultrasonography (US) was conducted which included the fetal weight, calculated by the use of Sheppard’s tables. This weight, estimated by US, was compared to the birth weight. Results: the results have proven that the clinical estimate used in this study has a similar value to that of the US calculation of birth weight. The accuracy of the clinical method, with variations of 5%, 10% and 15% between estimated and observed weights, was 55.3%, 73% and 86.7%, respectively. Those of the US were 60.7%, 75.4% and 91.1%, respectively. When comparing both sets of figures, values were not different from a statistical standpoint. Conclusion: the clinical evaluation has shown to be accurate, similarly to the US, when calculating the birth weight.

    Arthrogryposis multiplex congenita is characterized by multiple joint contractures present at birth. Prenatal diagnosis is difficult. There are few reports in the literature. Fetal akinesia, abnormal limb position, intrauterine growth retardation, and polyhydramnios are the main findings of the ultrasonographic diagnosis. The authors describe a case of arthrogryposis multiplex congenita ultrasonographically diagnosed in the third gestational trimester. The main findings were absence of fetal movements, polyhydramnios, symmetrical and non-symmetrical fetal growth retardation with marked decrease of abdominal and thoracic circumference, low-set ears, micrognathia, continuous flexure contracture of limbs, internal rotation of the femur, and clubfoot on the right.

    Purpose: to analyze the frequency of preoperative bilateral synchronic cancer and occult metastases in 454 operable breast cancer patients, at Instituto Nacional de Câncer (Brazil). Methods: the preoperative evaluation consisted of mammography, bone scan with X-ray if necessary, and chest X-ray. 260 (57.3 %) of 454 patients underwent liver echography. We calculated the cost X effectiveness ratio considering only the direct costs (monetary value) and the effectiveness was analyzed based on the number of metastases identifid by the screening tests. Results: we did not find any case of bilateral synchronic cancer, and the frequency of patients with metastasis was 2% (9/454). The diagnosis of bone metastasis was 1.5 % (7/454). The percentage of lung (2/454) and liver (1/260) metastasis was the same, 0.4 %. Most of the patients with metastases were in stage IIIb (44.5 %). The results of the screening tests showed the alteration of the initial clinical stage in 9 patients only (2%). The total cost of the screening tests for the diagnosis of systemic disease in 9 patients, was US$ 131,020.00. The cost of each diagnosed metastasise, for a total of 10 (two were found in one of the patients), was US$ 29,221.85 and the cost/effectiveness ratio was 22.3%. Conclusious: the results showed that screening for metastases in the preoperative clinical staging of breast cancer should be limited to patients symptomatic for systemic disease or in clinical stage III and that the cost/effectiveness ratio of the tests demonstrated a reduced benefit in the preoperative evaluation.

    Second-degree family history as a risk factor for breast cancer

    Purpose: to evaluate the association between second-degree family history of breast cancer and the risk to develop the disease. Methods: case-control study of incident cases. Sixty-six incident breast cancer cases and 198 controls were selected among women who were submitted to mammography in a private clinic between January 1994 and July 1997. Cases and controls were paired regarding age, age at menarche, at first live birth, at menopause, parity, oral contraceptives and use of hormonal replacement therapy. Results: there was no significant difference between cases and controls regarding all risk factors evaluated, besides second-degree family history. Patients with breast cancer were more likely to have second-degree relatives with breast cancer when compared to controls (OR=2.77; 95% CI, 1.03-7.38; p=0.039). Conclusions: malignant neoplasm of the breast is significantly associated with a second-degree family history of this disease.

    Purpose: to evaluate, in a prospective way, the performance of the fine needle aspiration biopsy in the differential diagnosis of palpable breast masses. Method: the sensitivity, specificity, positive and negative predictive values for this test were evaluated in 102 women with age above 30 years and a palpable breast mass, who were attended at the University of Campinas. All punctures were performed by the same examiner. Results: the procedure had a sensitivity of 97%, specificity of 87%, positive predictive value of 94% and negative predictive value of 93%. The insufficient or unsatisfactory sample rate was 16% for the first aspiration, decreasing to 2% with a new procedure. Conclusions: this test showed to be highly sensitive and specific for the differential diagnosis of palpable breast masses, reassuring its great importance for the clinical approach of palpable masses.
