[Treatment protocol for cervical carcinoma].

INTRODUCTION: Cervical cancer is the second most common cancer in women worldwide and the second cause of cancer death among women. About 95% (90% in developed countries) of invasive carcinomas are of squamous types, and 5% (10% in developed countries) are adenocarcinomas. FIGO classification of cervical carcinomas, based on clinical staging and prognostic factor dictate therapeutic procedures and help in designing treatment protocols. THERAPEUTIC MODALITIES: Surgical therapy includes conization, radical hysterectomy with pelvic lymphadenectomy and palliative operation--urinary diversion and colostomy. Radiotherapy, brachytherapy and teletherapy are most recently combined with chemotherapy as concurrent chemoradiation. DISCUSSION AND CONCLUSION: No change in therapeutic modalities will ever decrease mortality rate of cervical carcinoma as much as education, prevention and early screening. The 5-year survival for locally advanced disease has not improved during the last 40 years as a result of failure to deliver therapy to the paraaortic region. Paraaortic lymph nodes should be evaluated before therapy planning by different imaging procedures, or more exactly by surgical staging: laparoscopy or laparotomy. Radical operations of cervical carcinoma should be performed by experienced surgeons, educated for this type of operation, with sufficient number of cases.

[Olfactory perception in women with physiologically altered hormonal status (during pregnancy and menopause].

INTRODUCTION: Olfaction is considered to be the ability to: perceive, conduct and recognize scents and odors. With its numerous connections to the limbic system and reticular formation, the olfactory system affects regulation of numerous vegetative functions, visceral functions and sexual behavior. Since estrogen and progesterone protect the olfactory function, changes in their levels in particular physiological states in women (in pregnancy and posmenopause) exert an influence on the ability to feel and recognize smells. It has its role in creating emotions and adjustment of visceral and vegetative response to particular emotional states. Also, it represents the connection between higher cortical functions and the endocrine system. MATERIAL AND METHODS: Our investigation was performed at the Ear, Nose and Throat Clinic in Novi Sad. The research included 80 healthy women classified into 4 groups; 20 women aged between 20 and 30; 20 women in the first trimester of pregnancy aged between 20 and 30; 20 premenopausal women aged between 41 and 50; and 20 women at least 3 years in postmenopause, aged between 41 and 50. For our research we used an olfactometer and the Fortunato-Niccolini method. RESULTS AND DISCUSSION: In pregnancy the thresholds of perception (TP) and identification (TI) of examined substances were slightly lower in comparison to nonpregnant women of the same ages, but without any statistical significance (p > 0.05). In climacteric-postmenopausal women there was a significant decrease of olfactory ability in comparison to nonmenopausal women of the same ages (p < 0.01). CONCLUSION: All changes of the olfactory function in pregnancy are explained by mental changes of pregnant women as well as their hormonal status. Significant decrease of olfactory ability in postemnopause is explained by decline in sexual hormone levels.

[Amnionic infusion therapy in conditions with low amnionic fluid levels].

INTRODUCTION: Amniotic fluid volume reduction can have serious consequences: prior to 24 gestational weeks hypoplasia of fetal lungs and later in pregnancy cord compression and fetal hypoxia as well as contractions of extremities. Diagnosis of oligohydramnios is made either after a subjective estimation of amniotic fluid reduction or if the biggest amniotic fluid pocket is less than 1 cm. Amnioinfusion is a procedure during which a crystalloid solution, most often saline, is instilled into the amniotic cavity substituting amniotic fluid. To estimate the efficacy and safety of amnioinsfusion using our results and literature review. MATERIAL AND METHODS: Up to 800 ml of sterile saline solution was instilled intraamniotically (10-15 ml/min) in cases where the amniotic fluid index was less than 10 and intraamniotic infection was excluded. After that, 1 g of Longaceph was given intraamniotically. Infusion was stopped immediately when 800 ml was instilled, if a subjective estimation showed that there was enough fluid or if contractions occurred. RESULTS: During a six-month period there were five amnioinfusions--four therapeutical and one diagnostic; in four cases the procedure was successful and in one preterm rupture of membranes occurred 20 hours after the procedure. The procedure was most often done in the first half of the third trimester and continuation of pregnancy in successful cases was between 4 and 5 weeks, with average fetal weight gain of about 1200 gr. No complications occurred in cases where pregnancy continued. CONCLUSION: In our preliminary study amnioinfusion led to prolongation of pregnancy in majority of cases providing better maturation of fetal lungs and higher birth weight, without any complications. Further studies are necessary to reach definite conclusions about the efficacy and safety of amnioinfusion.

[Ovarian epithelial carcinoma--a malignant disease sparing no age group].

INTRODUCTION: Ovarian epithelial carcinoma is one of the most common gynecologic malignancies and the fifth most frequent cause of cancer death in women. Ovarian cancer affects women 65 years of age and older more frequently than younger women. MATERIAL AND METHODS: Four young patients with ovarian epithelial carcinoma were treated at the Institute of Oncology in Sremska Kamenica, Serbia and Montenegro, in the period 1981-2000. The median age at diagnosis was 17.3 years. Final histopathological findings revealed cystadenocarcinoma, either mucinous or serous. The stage of the disease was established using International Federation of Gynecology-Obstetrics (FIGO) Calssification. Spread of the disease dictated the extent of operation and post-operative chemotherapy. Patients were strictly followed-up at the Institute. RESULTS: The first two patients underwent unilateral adnexectomy as initial treatment. Final histopathological examination revealed an epithelial ovarian carcinoma, stage IIIa and IIb. Total hysterectomy with unilateral adnexectomy and total omentectomy were performed in both patients as second treatment with chemotherapy, according to the Cisplatin/Carboplatin and Cyclophos-phamide (CP) protocol following surgery. Another two patients underwent total hysterectomy with bilateral adnexectomy and total omentectomy as initial treatment with chemotherapy, CP protocol, following surgery. Both patients had stage IIc. Despite treatment, in two patients with stage IIIa and IIc, metastases were diagnosed. In 2 patients survival was over five years. One patient lived less than 3 years, and one less than 4 years. DISCUSSION: Ovarian carcinomas are difficult to diagnose at early stage. Histologic confirmation of the diagnosis, surgical staging, and aggressive surgical debulking, when possible, are all part of the initial evaluation and treatment. In most cases, surgery is followed by chemotherapy. The risk increases from 15.7 to 54 per 100,000 in the age group 40-79 years. Our study included 4 patients, medium age 17.3, with epithelial ovarian carcinoma which warns us to think twice when we get an adolescent patient with an adnexal mass. CONCLUSION: Advancing age, the major risk factor for development of ovarian carcinoma is, of course, unalterable. We investigated 4 patients medium age 17.3 years, with epithelial ovarian carcinoma. Pelvic masses found in women of reproductive age, must also be evaluated preoperatively to determine the probability of malignancy.

[Amnioreduction in treatment of increased amniotic fluid volume].

INTRODUCTION: Increased amniotic fluid volume may significantly increase the risk for preterm delivery. Amniodrainage is a symptomatic treatment by which excess amniotic fluid is reduced to provide fetal lung maturation. The aim of this stuldy is to estimate the efficacy and safety of this procedure, our results and give a literature review. MATERIAL AND METHODS: Sonografic criteria were used (AFI >400 ml, or the biggest amniotic fluid pocket >150 mm) to choose patients in whom 18G needle was used to allow leaking of excessive amniotic fluid. RESULTS: 10 patients underwent 26 procedures. The procedures were performed at 28.6 th week gestation, on average and 6.25 weeks average gain or 1000 g. We had two sets of monochorionic twins with twin-to-twin transfusion syndronme (TTTS), where one child survived. One procedure was followed by premature placental abruption, and premature delivery in 28th week. The rest of procedures were uneventful. CONCLUSION: In our series of 10 women, 26 procedures were performed to prolong pregnancies, enable fetal maturation and weight gain. In majority of cases amnioreduction was done without complications, so we could repeat the intervention and prolong the pregnancy. Survival of one child in two TTTS pregnancies should not be regarded unsulccessful in our conditions.
