RESUMEN

The expression pattern of c-sis, c-fos and c-jun was investigated in placenta and embryofetal organ specimens from the first trimester. Northern analysis of the placentae showed c-sis transcripts and c-fos expression. Northern analysis of the same genes in embryofetal organs pointed to the brain as the only organ where consistent transcriptional activity could be observed. RT-PCR analysis of c-fos and c-jun in placentae, staged at four different time periods in pregnancy, allowed to detect the expected fragments in all cases. The same was true when c-fos and c-jun were analyzed at the 13th week of gestation in all the embryofetal organs.

RESUMEN

OBJECTIVE: We evaluated the reliability of transvaginal ultrasonography in the differential diagnosis of adenomyoma versus leiomyoma. STUDY DESIGN: Preoperative transvaginal ultrasonographic results were compared with postoperative pathologic findings in 405 women who underwent surgery for symptomatic uterine nodularity. RESULTS: For adenomyoma diagnosis, transvaginal ultrasonography demonstrated a sensitivity of 87%, a specificity of 98%, a positive predictive value of 74.1%, and a negative predictive value of 98.6%, compared with a sensitivity of 96.1%, a specificity of 83.3%, a positive predictive value of 98.4%, and negative predictive value of 35.7% for leiomyoma diagnosis. CONCLUSION: Transvaginal ultrasonography is an effective, noninvasive, and relatively inexpensive procedure for the preoperative differential diagnosis of adenomyoma versus leiomyoma.

RESUMEN

We studied the endometrial structure and ultrastructure in serial biopsies from 16 patients with endometriosis treated with danazol (n = 9) or the combination cyproterone acetate plus ethinyl estradiol (n = 7) for 6 months. Biopsies were performed before and at 3 and 6 months of treatment. The material obtained was studied by light (LM), scanning (SEM) and transmission electron microscopy (TEM). A morphometric analysis was performed evaluating three morphometric and three stereologic indices. The results indicate that danazol had a progestational effect on endometrial glands and stroma, associated with a marked hypotrophy of the mucosa. The cyproterone acetate/ethinyl estradiol combination induced progressive atrophy of the endometrium with an increase in the stromal component and a reduction of glandular tissue.

RESUMEN

Seventy-one women with symptomatic uterine myomas, hospitalized for hysterectomy, underwent preoperative transvaginal ultrasonography and hysteroscopy to compare their reliability in the diagnosis of submucous myomas. After the operation, the surgical specimen was studied carefully and the results were compared with the preoperative diagnostic findings. Transvaginal ultrasonography had a sensitivity of 100% and specificity of 94%; the predictive value of an abnormal ultrasound scan was 81% and that of a normal one was 100%. The sensitivity of hysteroscopy was 100% and the specificity 96%; the predictive value of an abnormal hysteroscopic finding was 87% and that of a normal result was 100%. Mapping of uterine myomas is more precise with transvaginal ultrasonography than with hysteroscopy, but the former method cannot distinguish between a myoma and an endometrial polyp.

RESUMEN

We performed hysteroscopic metroplasty in 21 women with repeated abortion and subseptate uterus. The patients were randomly allocated to septal incision with the argon laser (group I, 10 subjects) or microscissors (group II, 11 subjects) to compare these instruments in terms of surgical feasibility and anatomic results. The mean operating time was 57% longer in group I than in group II (p = 0.001), the intra- and postoperative morbidity of the whole series was negligible, and the anatomic results at abdominal ultrasonography and hysteroscopy performed 2 months postoperatively were similar in the two groups. This study confirms that microscissors are the simplest, fastest, most effective, and least expensive instrument to correct a septate uterus. The complete agreement of the findings at follow-up hysteroscopy and ultrasonography suggest the use of the latter as the method of choice to check the surgical results.

RESUMEN

Six girls with suspected Rokitansky syndrome underwent magnetic resonance imaging (MRI) and then sonography and laparoscopy to confirm the clinical diagnosis and define the precise characteristics of the malformation. The uterus was missing in all; four had müllerian rudiments in place of the uterus, which were cavitary in two as shown by sonography and in one by MRI. Both ovaries were present in all cases, normally located in four and extrapelvic in two; they were correctly identified by MRI in all cases and by sonography in four. Partially canalized vaginal rudiments were recognized by MRI in two girls and by sonography in one. One patient had unilateral renal agenesis, demonstrated by both MRI and sonography. Magnetic resonance imaging was more precise than laparoscopy and sonography in defining the anatomical characteristics of Rokitansky syndrome, and is less invasive and expensive than laparoscopy.

RESUMEN

We studied 30 spontaneous cycles, 30 cycles induced with clomiphene citrate, and 30 cycles induced with human menopausal gonadotropin-human chorionic gonadotropin to evaluate the pattern of the following parameters and their predictive value in timing ovulation: basal body temperature; cervical mucus; mean follicular diameter; serum LH and 17-beta-estradiol; and urinary LH. Compared with the spontaneous cycles, in the cycles induced with clomiphene citrate the cervical score was significantly lower on the 4 days preceding ovulation, serum LH was higher in the early follicular phase, and serum 17-beta-estradiol was significantly higher in the pharmacologically treated cycles. The highest predictive values in all groups of cycles were obtained by considering the following combinations of parameters: serum 17-beta-estradiol and LH concentrations; mean follicular diameter as shown by ultrasonography and urinary LH as determined by a rapid method.

RESUMEN

Twenty-four women with symptomatic multiple uterine myomas were allocated randomly to treatment with buserelin, 1200 micrograms/day intranasally, for 3 months followed by myomectomy (n = 8) or to immediate myomectomy (n = 16). Pre-operative treatment with buserelin reduced the mean uterine volume from 432 (SD 165) to 242 (SD 82) ml (P less than 0.01) but intra-operative blood loss and postoperative morbidity were not significantly less in this group. Six months after operation, pelvic examination was normal in all the patients. However, ultrasonography with transvaginal probe demonstrated the presence of myomas of less than 1.5 cm in five women (63%) treated pre-operatively with the analogue and in two women (13%) who underwent immediate surgery (P less than 0.05). Induction of a period of hypo-oestrogenism before myomectomy seems to favour short-term recurrence of uterine myomas, limiting the efficacy of surgery.

RESUMEN

We describe a case of primary alveolar soft part sarcoma presenting as a vaginal mass in a 27 year old woman and also review the literature on this type of tumor arising in the lower female genital tract. Histologically, most of the tumor exhibited poorly developed alveolar architecture, but anaplasia was absent. Although the mass was well circumscribed, a few tumor cells were seen focally within the peritumoral tissue. Treatment consisted of wide local excision followed by external radiation therapy. The patient is alive without evidence of disease 17 years after operation.

RESUMEN

We measured basal body temperature, cervical mucus, follicular diameter, and serum LH, FSH, 17 beta-estradiol, and progesterone daily in 40 spontaneous ovulatory cycles in 27 infertile women and in 40 clomiphene citrate-induced ovulatory cycles in 31 women. The cervical score was significantly lower and the serum FSH, LH, and 17 beta-estradiol levels were significantly higher during the follicular phase in induced compared with spontaneous cycles. Serum progesterone was significantly higher on the 3 days preceding ovulation and the day of ovulation in the induced cycles. These increased preovulatory serum progesterone levels could contribute to the lower cervical mucus score in the induced compared with spontaneous cycle, whereas their effect on the endometrium is still unclear.

RESUMEN

We compared ovulatory changes in fertile and preceding infertile cycles in 21 patients with unexplained infertility conceiving after clomiphene citrate treatment. No significant differences were observed in follicular growth, cervical score and follicle stimulating hormone (FSH) levels. Progesterone was higher (P less than 0.05) in the 2 days preceding ovulation in fertile cycles, luteinizing hormone (LH) higher (P less than 0.05) the day before, and 17-beta-estradiol lower (P less than 0.05) 4 days before. Stimulating progesterone secretion by systematic LH administration before ovulation could improve secretory endometrial transformation and thus reproductive prognosis.

RESUMEN

Fourteen infertile women with hysterographic diagnoses of unicornuate uterus underwent pelvic ultrasonography and, subsequently, laparoscopy to evaluate the ability of ultrasound to diagnose the subclasses of this malformation. Seven women underwent laparotomy to remove a rudimentary horn. Ultrasound demonstrated a sensitivity of 85.7% and a specificity of 100% in diagnosing the presence of a rudimentary horn, and a sensitivity of 80% and a specificity of 100% in diagnosing the presence of a cavity in the rudimentary horn. Urography confirmed the supplementary information on the urinary tract provided by ultrasound. Ultrasound appears to have a role in the clinical management of women with unicornuate uterus.
