התרופה מיזופרוסטול (misoprostol) היא אנאלוג לפרוסטגלנדין (prostaglandin) E1. מזה כ-8 שנים התרופה מצויה בניסיונות קליניים במיילדות לצורך השראת לידה או הבשלת צוואר-הרחם. המטרה במאמר זה היא סקירת הספרות העדכנית על יעילותה של התרופה, בטיחות הטיפול בה והמינונים המקובלים בהשראת לידה. הסקירה מתבססת על תוצאות 33 מאמרים שפורסמו בין השנים 1993-2001. איסוף הנתונים התבצע באתרי האינטרנט ה- pubmed וה-medline ובסקירות.

מיזופרוסטול היא תרופה יעילה במידה שווה או יותר מהתרופות הנהוגות כיום להשראת לידה (פרוסטגלנדין E2 ואוקסיטוצין). התרופה עמידה לאורך שנים ועלותה נמוכה. חסרונותיה נעוצים בנטייתה לעורר פעילות מוגברת של הרחם, כטאכיסיסטולה וגריית-יתר (hyperstimulation), ובחשש מקרע של הרחם. ניתן להתמודד עם התופעות הללו על-ידי נקיטת צעדי בטיחות, כגון הקטנת מינון התרופה, הגדלת מירווחי המתן ובחירה זהירה של המטופלות המתאימות.

לסיכום, מיזופרוסטול היא תרופה חשובה ויעילה לצורך השראת לידה, ויש מקום להכניסה לניסיונות קליניים גם בישראל.

Laparoscopy as Part of the Management of Gynecologic Neoplasms - Report of Our Clinical Experience

Introduction: Surgery is the treatment of choice in most early stages of cervical cancer and advanced stages of ovarian cancer. Failing to preoperatively diagnose para-aortic and parametrial metastases in cervical cancer or a non-resectable, ovarian cancer, may results in a superfluous laparotomy.

Aim: To evaluate the advantage of using laparoscopy in cervical and ovarian cancer.

Patients and Methods: Study population includes patients with ovarian or cervical cancer referred between 1997-1999. A CT scan and a trans-vaginal sonography were used to detect involvement of pelvic and para-aortic lymph nodes, parametrium and other metastases. In patients with cervical cancer, para-aortic lymph node dissection was laparoscopically performed. When para-aortic nodes were negative and parametrium was clear, radical hysterectomy and pelvic lymph nodes dissection was conducted through laparotomy. When para-aortic lymph nodes or parametrium were positive, patients were referred for radiation therapy. In ovarian cancer patients, the upper abdomen and the pelvis were examined laparoscopically to evaluate the possibility of optimal debulking surgery. Staging was done for patients who were not candidates for optimal debulking surgery and second debulking surgery was considered.

Results: Nine patients with stage lb-lla cervical cancer were included. Preoperatively, 2 of them were suspected for lymph node involvement. Following laparoscopy one was confirmed to have para-aortic lymph node involvement and the other did not. In the remaining 8 patients, one was found to have parametrial involvement and laparotomy was avoided, while the rest were treated surgically.

Eighteen ovarian cancer patients were included in this study. Laparoscopy revealed an extensive disease in 7 patients and therefore staging laparoscopy was completed. In the remaining 11 patients, laparotomy was performed, operable disease was found and complete debulking surgery was conducted. In only one patient of the 11 complete debulking surgeries was not possible.

Conclusions: In accordance with the experience and skills of the surgical team, we propose utilizing laparoscopy in cases where laparotomy may be avoided.

Mirena, a new intra-uterine device (IUD) introduced in Israel during the past year, releases 20 mcg/day of levonorgestrel for 5 years. It has the advantages of reduced pregnancy rates and diminished menstrual blood loss, together with a low risk of pelvic inflammatory disease compared with current IUD's.

It has a typical sonographic appearance, differing from that of regular IUD's, which was demonstrated in all 15 women examined in this study. Its sonographic appearance includes both proximal and distal ends of the vertical arm of the device, which extend into the internal cervical os and fundal region, respectively. Acoustic shadowing between both ends defines the location of the device, which should help avoid consultations due to "lost IUD's."

During 1971-1996, 17 patients with mixed mesodermal uterine tumors were treated. Average age at diagnosis was 67.3 years, 12/17 were of European and 5/17 of Afro-Asian extraction. The overall 5-year survival was 21%. 10/17 patients had mixed mesodermal tumors with a heterologous mesenchy-mal element, and 7/17 had a homologous mesenchymal element (carcinosarcoma). 6/17 had another primary malignancy, including breast cancer (3/17), bilateral metachronous breast tumor (2/17), and malignant lymphoma of the neck region (2/17). All 3 with breast cancer had previously been treated with tamoxifen. 1 had simultaneous mesodermal tumor and ovarian thecoma. Simultaneous autoimmune manifestations occurred in 2/17, including thrombocytopenic purpura in 1, and myasthenia gravis in another. Mesodermal tumor of the uterus is a relatively rare malignancy with aggressive behavior and poor prognosis. It also had unusual associations with other primary tumors, hormonal treatment, and autoimmune manifestations.

The incidence of ectopic endometriosis is 4% to 18%. The intestinal type is quite common with the rectosigmoid the most likely part of the bowel to be involved due to its pelvic location. A 43-year-old woman, whose symptoms, X-ray and endoscopic findings suggested malignancy of the rectosigmoid, is presented. Primary malignancy of the bowel was excluded by endoscopic biopsies. Histological examination at operation showed stromal sarcoma of the uterus with foci of endometriosis. There is no report in the English literature of transformation of intestinal endometriosis into malignancy, such as stromal sarcoma of the uterus, which imitates a primary malignancy with obstruction of the rectosigmoid.
