Impact of myocardial injury after coronary artery bypass grafting on long-term prognosis.

AIMS: The most appropriate definition of perioperative myocardial infarction (pMI) after coronary artery bypass grafting (CABG) and its impact on clinically relevant long-term events is controversial. We aimed to (i) analyse the incidence of pMI depending on various current definitions in a 'real-life' setting of CABG surgery and (ii) determine the long-term prognosis of patients with pMI depending on current definitions. METHODS AND RESULTS: A consecutive cohort of 2829 coronary artery disease patients undergoing CABG from two tertiary university centres with the presence of serial perioperative cardiac biomarker measurements (cardiac troponin and creatine kinase-myocardial band) were retrospectively analysed. The incidence and prognostic impact of pMI were assessed according to (i) the 4th Universal Definition of Myocardial Infarction (4UD), (ii) the definition of the Society for Cardiovascular Angiography and Interventions (SCAI), and (iii) the Academic Research Consortium (ARC). The primary endpoint of this study was a composite of myocardial infarction, all-cause death, and repeat revascularization; secondary endpoints were mortality at 30 days and during 5-year follow-up. There was a significant difference in the occurrence of pMI (49.5% SCAI vs. 2.9% 4UD vs. 2.6% ARC). The 4th Universal Definition of Myocardial Infarction and ARC criteria remained strong independent predictors of all-cause mortality at 30 days [4UD: odds ratio (OR) 12.18; 95% confidence interval (CI) 5.00-29.67; P < 0.001; ARC: OR 13.16; 95% CI 5.41-32.00; P < 0.001] and 5 years [4UD: hazard ratio (HR) 2.13; 95% CI 1.19-3.81; P = 0.011; ARC: HR 2.23; 95% CI 1.21-4.09; P = 0.010]. Moreover, the occurrence of new perioperative electrocardiographic changes was prognostic of both primary and secondary endpoints. CONCLUSION: Incidence and prognosis of pMI differ markedly depending on the underlying definition of myocardial infarction for patients undergoing CABG. Isolated biomarker release-based definitions (such as troponin) were not associated with pMI relevant to prognosis. Additional signs of ischaemia detected by new electrocardiographic abnormalities, regional wall motion abnormalities, or coronary angiography should result in rapid action in everyday clinical practice.

[Analysis of udder health in relation to antimicrobial usage in Swiss dairy farms]. / Analyse der Eutergesundheit in Zusammenhang mit dem Antibiotika­verbrauch in Schweizer Milchvieh­betrieben.

INTRODUCTION: In Switzerland, standards for milk quality are high. This requires a high level of udder health in dairy cows. Previous studies have shown that mastitis and antibiotic dry cow treatments are the most common causes of antimicrobial consumption in dairy cows. This raises the question of whether a high use of antibiotics is necessary to maintain good udder health. The aim of this study was to analyze the relationship between udder health and antimicrobial usage in Swiss dairy farms. A total of 84 participating farms were evaluated over a period of 18 months. Udder health was assessed using the yield corrected bulk milk somatic cell count from the monthly milk yield data and the number of lactating cows over 150'000 cells/ml per month. Data on antimicrobial consumption were also collected on a monthly basis. In a hierarchical regression model, a significant association between udder health and intramammary antibiotics used during lactation was found. The month of Measurement of the Somatic Cell Count and the veterinarian also had a statistically significant influence on udder health. The consumption of antibiotics for dry cow treatments was not associated with udder health. Antibiotics administered systemically and the production label of the farms was also not statistically associated with udder health in our models. The study was able to show that good udder health is possible with low antimicrobial usage.

INTRODUCTION: En Suisse, les exigences en matière de qualité du lait et, partant, de la santé de la mamelle dans les exploitations laitières sont élevées. Des études antérieures ont montré que les maladies de la mamelle et les tarissements aux antibiotiques sont la principale cause de l'usage d'antibiotiques chez les vaches laitières. Par conséquent, la question s'est posée de savoir si une utilisation importante d'antibiotiques est nécessaire au maintien d'une bonne santé de la mamelle. Le but de cette étude était d'analyser la relation entre la santé de la mamelle et la consommation d'antibiotiques. La santé de la mamelle a été évaluée au moyen du nombre théorique de cellules dans le tank à lait à partir des données du contrôle laitier mensuel et du nombre d'animaux présentant plus de 150 000 cellules/ml par mois. Des données sur la consommation d'antibiotiques ont également été collectées mensuellement. Les données totales de 84 exploitations sur une période de 18 mois ont pu être évaluées. Dans un modèle de régression hiérarchique, une corrélation significative entre la santé de la mamelle et les antibiotiques appliqués en intra mammaires pendant la lactation a été constatée. Le mois de pesée ainsi que le vétérinaire traitant ont également eu un impact significatif sur la santé de la mamelle. La quantité de préparations antibiotiques utilisées pour la phase de tarissement ne correspondait pas à la santé de la mamelle dans les exploitations. Les antibiotiques administrés par voie systémique de même que le label de production des exploitations ne sont pas non plus significatifs. L'étude a montré qu'une bonne santé de la mamelle est possible même avec une faible utilisation d'antibiotiques.

Tryptophan hydroxylase gene polymorphism (A218C) and idiopathic recurrent miscarriage.

OBJECTIVE: To investigate the frequency of a polymorphism in intron 7 of the tryptophan hydroxylase gene among women with idiopathic recurrent miscarriage and healthy controls. METHODS: In a case control study, we studied 125 women with a history of three or more consecutive pregnancy losses before 20 weeks' gestation and 137 healthy controls with at least two live births and no history of pregnancy loss. Peripheral venous puncture, DNA extraction, and polymerase chain reaction followed by restriction fragment length polymorphism analysis were used to genotype women for the presence of the A218C polymorphism in intron 7 of the tryptophan hydroxylase gene. RESULTS: Allele frequencies among women with idiopathic recurrent miscarriage and controls were 32.4% and 38.7%, respectively, for allele A (wild type) and 67.6% and 61.3%, respectively, for allele C (mutant). No association between the presence of allele C and idiopathic recurrent miscarriage was found (P = .3; odds ratio 1.31; 95% confidence interval 0.93, 1.87). Genotype frequencies also were not significantly different between the study group (C/C: 44.8%; A/C: 45.6%; A/A: 9.6%) and the control group (C/C: 37.2%; A/C: 48.2%; A/A: 14.6%; P = .2). Between women with primary and women with secondary idiopathic recurrent miscarriage, no statistically significant differences with respect to allele frequencies were observed (63% vs 62% for allele C and 31% vs 38% for allele A; P = .3). CONCLUSION: The A218C polymorphism in intron 7 of the tryptophan hydroxylase gene is not associated with idiopathic recurrent miscarriage.

2500 Outpatient diagnostic hysteroscopies.

OBJECTIVE: To evaluate the feasibility and acceptability of outpatient diagnostic hysteroscopy. METHODS: The outcome of 2500 consecutive outpatient hysteroscopies was analyzed. Cervical dilation was performed when necessary and local anesthesia was not administered routinely. Endometrial biopsy and minor hysteroscopic procedures were carried out when indicated. Findings and outcome were compared according to patient characteristics. RESULTS: The most common indication for hysteroscopy was abnormal uterine bleeding (87%). Hysteroscopy was performed successfully in 96.4%, and a complete view of the uterine cavity was obtained in 88.9%. Local anesthesia was used in 29.8% and was associated with the need for cervical dilation; both local anesthetic use and cervical dilation were significantly more often required in nulligravid, nulliparous, and postmenopausal women. Intrauterine pathology was diagnosed in 48%, the highest incidence being found in those 50-60 years old (53.7%). The presence of fibroids was the most common abnormality (24.3%) but was seen in only 6.8% of women older than 60 years. Conversely, the incidence of endometrial polyps increased with age, up to 20.5% in women over 60 years. Endometrial biopsy was performed in 68% and produced adequate tissue for histologic examination in 83.7%. Endometrial hyperplasia or carcinoma was detected in 1%. One hundred sixteen women (4.6%) underwent a minor hysteroscopic procedure. CONCLUSION: Outpatient diagnostic hysteroscopy is both feasible and acceptable in the overwhelming majority of cases, with a high detection rate for intrauterine pathology. This procedure may become as routine in the 21st century as D&C has been in the 20th.

Preoperative CA 125: an independent prognostic factor in patients with stage I epithelial ovarian cancer.

OBJECTIVE: To evaluate the prognostic importance of preoperative CA 125 levels in patients with International Federation of Gynecology and Obstetrics (FIGO) stage I epithelial ovarian cancer in comparison with the established prognostic factors: degree of differentiation, FIGO substage, and age. METHODS: In a retrospective analysis, the traditional prognostic factors and CA125 levels (cutoff value 65 U/mL) were studied in 201 patients who were treated in five centers during 1984-1993. Patients with borderline tumors or non-epithelial ovarian carcinomas were excluded, as were women in whom CA 125 had not been determined preoperatively. RESULTS: In univariate analysis (Mantel test), overall survival decreased significantly in patients positive for CA 125 (P < .001). Substage (P = .004) and histologic grade (P = .01) also significantly influenced survival prognosis. When the effects of preoperative CA 125 levels were correlated with histologic grade, all three subgroups with CA 125 levels equal to or greater than 65 U/mL were associated with a decreased survival probability (grade 1, P = .04; grade 2, P = .003; grade 3, P = .01). Multivariate analysis (Cox model) identified preoperative CA 125 as the most powerful prognostic factor for survival (P < .001), the risk of dying of disease being 6.37 times higher (95% confidence interval 2.39-16.97) in CA 125-positive patients. Although FIGO substage retained its significant influence on survival (P = .03), histologic grade and age were not prognostically important. CONCLUSION: Randomized trials investigating the efficacy of adjuvant treatment in patients with FIGO stage I epithelial ovarian cancer should also include stratification by preoperative CA 125 levels.

Why do women choose endometrial ablation rather than hysterectomy?

OBJECTIVE: To determine why women choose endometrial ablation rather than hysterectomy for the treatment of menorrhagia. DESIGN: Observational study based on postal questionnaires. SETTING: A university hospital. PATIENT(S): One hundred eighty randomly selected patients from a cohort of 658 patients who underwent endometrial ablation for the treatment of menorrhagia during the past 7 years. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Patient attitude about endometrial ablation. RESULT(S): One hundred six questionnaires (58.9%) were completed satisfactorily. The average postoperative follow-up period was 45.1 months (range, 3-80 months). Eleven women (10.4%) had undergone repeated endometrial ablation and 8 (7.5%) had undergone hysterectomy. More than half the women indicated that they would find endometrial ablation acceptable even if there was no chance of amenorrhea, if the probability of menstruation becoming lighter was > or = 4:10, if the likelihood of menstrual pain decreasing was > or = 3:10, if the chance of requiring repeated endometrial ablation or hysterectomy was < or = 1:4, and if the risk of uterine cancer after surgery was < or = 1:200. The three most important advantages of endometrial ablation over hysterectomy were perceived to be the avoidance of major surgery, the fast return to normal functioning, and the short hospitalization. CONCLUSION(S): Most women who choose endometrial ablation rather than hysterectomy as therapy for menorrhagia are prepared to undergo hysteroscopic surgery even if the chance of success is relatively poor.

Lignocaine aerosol spray in outpatient hysteroscopy: a randomized double-blind placebo-controlled trial.

OBJECTIVE: To assess the efficacy of lignocaine spray during outpatient hysteroscopy in reducing the need for additional anesthesia and reducing the discomfort of the procedure. DESIGN: A randomized double-blind, placebo-controlled trial. SETTING: An undergraduate university teaching hospital in London. PATIENT(S): One hundred twenty patients undergoing outpatient hysteroscopy. INTERVENTION(S): Application of lignocaine spray to the cervix, cervical canal, and uterine cavity during outpatient hysteroscopy. MAIN OUTCOME MEASURE(S): The need to use additional anesthesia and the pain experienced at various steps of the procedure. RESULT(S): Women treated with active spray experienced significantly less pain when the cervix was grasped with a tenaculum at the start of hysteroscopy. There were no other significant differences in the outcome of hysteroscopy between the placebo and lignocaine groups, although there was a significant reduction in the use of additional anesthesia in both groups compared with historical controls. CONCLUSION(S): Lignocaine spray has beneficial effects on cervical but not uterine sensation. Pretreatment with either lignocaine or placebo seems to reduce the need for additional intracervical anesthesia during hysteroscopy.

Effects of tibolone on auditory brainstem responses in postmenopausal women--a randomized, double-blind, placebo-controlled trial.

OBJECTIVE: To investigate the influence of tibolone, a synthetic steroid, in modifying auditory brainstem response (ABR) in postmenopausal women. DESIGN: Prospective, randomized, double-blind, placebo-controlled trial. SETTING: Outpatient menopausal clinic in a university hospital. PATIENT(S): Twenty-four healthy postmenopausal women. INTERVENTION(S): Administration of either tibolone or placebo for 12 weeks; evaluation of ABR and hormone levels before and after treatment. MAIN OUTCOME MEASURE(S): Changes in auditory brainstem response latencies. RESULT(S): Comparison of the ABR latency data from the two treatment groups showed a significant decrease in wave II, III, and V peak latencies in women receiving tibolone. No significant differences in pretreatment and posttreatment circulating hormone concentrations were observed between the tibolone and placebo group. Furthermore, there was no significant increase in hormone levels in either of the groups at 12 weeks. CONCLUSION(S): Our findings show an improvement in auditory function via brainstem auditory neural pathways sensitive to tibolone in postmenopausal women. Tibolone may offer new therapeutic strategies in otologic disorders.

Hysteroscopy in women with abnormal uterine bleeding on hormone replacement therapy: a comparison with postmenopausal bleeding.

OBJECTIVE: To determine the role of outpatient diagnostic hysteroscopy in patients with abnormal uterine bleeding (AUB) on hormone replacement therapy (HRT) and to contrast this with a control group of women presenting with postmenopausal bleeding. DESIGN: Comparative observational study. SETTING: Outpatient hysteroscopy clinic in a university hospital. PATIENTS: Three hundred ten patients undergoing outpatient hysteroscopy. INTERVENTIONS: Outpatient diagnostic hysteroscopy with endometrial biopsy when indicated. MAIN OUTCOME MEASURES: Hysteroscopic findings, need for cervical dilatation and local anaesthesia, correlation between hysteroscopy and histologic diagnosis. RESULTS: There were 157 (7.1%) patients with AUB on HRT and another 153 (6.9%) with postmenopausal bleeding out of 2,203 outpatient hysteroscopies. Hysteroscopy was successful in 97% and 92% of patients, respectively, and intrauterine pathology was diagnosed in 46.7% and 39.7% of these cases. Functional endometrium was noted significantly more often with HRT and endometrial atrophy with postmenopausal bleeding. Overall, local anesthesia was used in 126 (40.6%) and shown to be associated significantly with the need for cervical dilatation. Endometrial biopsy was attempted in 125 (80%) and 119 (78%) patients in the study and control groups, but was unsuccessful significantly more often with postmenopausal bleeding (38.7%) versus 16%). There were six cases of endometrial carcinoma, all in the control group. CONCLUSION: There is a high incidence of intrauterine abnormalities in women with menstrual symptoms while taking HRT, but the pathology differed from those with postmenopausal bleeding. As focal lesions are found commonly in such patients, their detection by diagnostic hysteroscopy should improve compliance with HRT as it would allow individualization of treatment.

Comparison of carbon dioxide and normal saline for uterine distension in outpatient hysteroscopy.

OBJECTIVE: To evaluate patient acceptance and the clinical feasibility of carbon dioxide compared with normal saline for uterine distension in outpatient hysteroscopy. DESIGN: Prospective, randomized clinical trial. SETTING: Outpatient hysteroscopy clinic in a university hospital. PATIENTS: One hundred fifty-seven patients undergoing outpatient hysteroscopy. INTERVENTIONS: Outpatient hysteroscopy was performed with carbon dioxide or normal saline with endometrial biopsy when indicated. MAIN OUTCOME MEASURES: Need for local anesthesia, cervical dilatation, view of uterine cavity, need to change from carbon dioxide to normal saline distension, procedure time, patient discomfort (lower abdominal pain, shoulder tip pain, nausea) and complications. RESULTS: Carbon dioxide was used for uterine distension in 79 women and normal saline was used in 78. Cervical dilatation was required more often with carbon dioxide hysteroscopy, although there was no increased requirement for local anesthesia. Hysteroscopic vision was similar between the two media, but eight carbon dioxide cases had to be converted to liquid distension. Procedure times were significantly longer for carbon dioxide hysteroscopy as was the occurrence of bubbles during the procedure. Lower abdominal pain and shoulder tip pain were significantly worse with carbon dioxide distension. Although the incidence of nausea and vomiting was higher with the use of carbon dioxide, the differences did not achieve statistical significance. CONCLUSION: The use of normal saline for uterine distension had no adverse affects on the hysteroscopic view. It provided a shorter operating time and was well accepted by patients. Because of its easy availability and low cost, normal saline is an excellent alternative to carbon dioxide in women undergoing outpatient hysteroscopy.

Atraumatic cervical passage at outpatient hysteroscopy.

OBJECTIVE: To evaluate the efficacy of topical anesthesia routinely administered to reduce discomfort and the need for additional local anesthesia during outpatient hysteroscopy. DESIGN: Comparative observational study. SETTING: Outpatient hysteroscopy clinic in a University hospital. PATIENT(S): Three hundred patients undergoing outpatient hysteroscopy. INTERVENTION(S): Application of lidocaine spray both to the surface of the cervix and into the cervical canal before performing hysteroscopy. MAIN OUTCOME MEASURE(S): The discomfort during passage of the hysteroscope through the cervical canal, the need for additional local anesthesia, and the failure rate of outpatient hysteroscopy. RESULT(S): One hundred fifty consecutive patients receiving lidocaine spray before the hysteroscopy were compared to a control group of another 150 consecutive patients who underwent the examination without pretreatment. Women treated with spray experienced significantly less pain at insertion of the hysteroscope. Furthermore, the spray significantly reduced both the need for additional anesthesia and the rate of failed hysteroscopies due to intolerable pain. CONCLUSION(S): Topical anesthesia with lidocaine spray is a simple method to alleviate patients' discomfort during cervical passage. It is effective in reducing the need for local anesthesia and should reduce the rate of failed outpatient hysteroscopies.

Interleukin 1 receptor antagonist polymorphism in women with idiopathic recurrent miscarriage.

OBJECTIVE: Proinflammatory cytokines have been described as etiologic factors in idiopathic recurrent miscarriage. We investigated the relation between idiopathic recurrent miscarriage and polymorphisms in the gene encoding for the interleukin 1 receptor antagonist, an indigenous modulator of proinflammatory immune response. DESIGN: Prospective case control study. SETTING: Academic research institution. PATIENT(S): One hundred five women with a history of three or more consecutive pregnancy losses before 20 weeks of gestation and 91 healthy, postmenopausal controls with at least two live births and no history of pregnancy loss. INTERVENTION(S): Peripheral venous puncture. MAIN OUTCOME MEASURE(S): Polymerase chain reaction was performed to identify the different alleles of the gene encoding for interleukin 1 receptor antagonist. RESULT(S): Allele frequencies among women with idiopathic recurrent miscarriage and controls were 0.34 and 0.11, respectively, for the polymorphic allele 2 (P=.002; odds ratio: 7.4, confidence interval: 2.9--10.8) and.05 and.05, respectively, for the polymorphic allele 3 (P=.6; odds ratio: 1.3, confidence interval: 0.8--2.3). Allele 2 was present in homozygous form in 9% of women with idiopathic recurrent miscarriage. In contrast, 1% of the control women were homozygous for this allele (P<.001; odds ratio: 13.5, confidence interval: 7.5--21.8). CONCLUSION(S): These data support a role for allele 2 of the gene encoding for interleukin 1 receptor antagonist as genetic determinant of idiopathic recurrent miscarriage.

A polymorphism of the interleukin-1beta gene and idiopathic recurrent miscarriage.

OBJECTIVE: Proinflammatory cytokines have been described to be involved in the pathogenesis of idiopathic recurrent miscarriage (IRM). We investigated the association between IRM and a polymorphism in exon 5 of the interleukin-1beta gene (IL1B) and interleukin-1beta (IL-1beta) serum levels. DESIGN: Case control study. SETTING: Academic research institution. SUBJECTS: One hundred thirty-one women with a history of three or more consecutive pregnancy losses before 20 weeks' gestation and 68 healthy controls with at least two live births and no history of pregnancy loss. INTERVENTIONS: Peripheral venous puncture. MAIN OUTCOME MEASURES: An IL1B exon 5 (position +3953) gene polymorphism was analyzed by PCR amplification followed by restriction fragment length polymorphism analysis. IL-1beta serum levels were analyzed by a commercially available ELISA. RESULTS: Allele frequencies in women with IRM and controls were 77.9% and 80.8%, respectively, for the E1 allele (wild type), and 22.1% and 19.2%, respectively, for the E2 allele (mutant). No association between the E2 allele and the occurrence of IRM was found (P=.57, odds ratio =.83). Genotype frequencies and IL-1beta serum levels were not significantly different between the study group and the control group. CONCLUSIONS: This is the first report on an IL1B polymorphism in IRM. Although known to alter IL-1beta expression, the investigated IL1B polymorphism is not associated with IRM and increased serum levels in a large Caucasian population.

The PROGINS progesterone receptor gene polymorphism and idiopathic recurrent miscarriage.

OBJECTIVE: Progesterone inhibits lymphocyte cytotoxicity, natural killer cell degranulation, and release of proinflammatory cytokines and has been shown to protect against spontaneous miscarriage. We investigated the association between idiopathic recurrent miscarriage (IRM) and the PROGINS 306 base pair insertion polymorphism in intron G of the progesterone receptor gene, which is known to segregate with progesterone-dependent neoplasms. METHODS: In a case-control study we investigated 125 women with a history of three or more consecutive pregnancy losses before 20 weeks' gestation and 79 healthy controls with at least two live births and no history of pregnancy loss. Peripheral venous puncture, DNA extraction, and polymerase chain reaction were used to genotype women for the presence of the PROGINS polymorphism. RESULTS: Allele frequencies among women with IRM and controls were 85.2% and 89.2%, respectively, for allele T1 (wild type) and 14.8% and 10.8%, respectively, for allele T2 (mutant). No association between allele T2 and the occurrence of IRM was found (P =.3; odds ratio [OR] 0.69; confidence interval [CI] 0.34, 1.40). Genotype frequencies were not significantly different between the study group (T1/T1 73.6%, T1/T2 23.2%, T2/T2 3.2%) and the control group (T1/T1 79.7%, T1/T2 19%, T2/T2 1.3%) (P =.4). Between women with primary and secondary IRM, there were no statistically significant differences with respect to allele frequencies (82% versus 87%, P =.4 for allele T1 and 12% versus 13%, P =.6 for allele T2). CONCLUSIONS: We found that the PROGINS polymorphism in the progesterone receptor gene was not associated with IRM in white women.

Clinical profile of a new hormone replacement therapy containing 2 mg 17 beta-estradiol and 10 mg dydrogesterone.

OBJECTIVE: Patient's acceptability, compliance, and effectiveness of a new sequential hormone replacement regimen containing 2 mg 17beta-estradiol and 10 mg dydrogesterone, were assessed in a 3-month, open, multicentre study involving 110 menopausal women. METHODS: A specially designed menopause score was used to assess the severity of menopausal symptoms, each symptom being graded at baseline and after 3 months on a four-point scale. Bleeding data were recorded by the patient on a diary card. Serum hormone levels including FSH, LH, E2, P, PRL, DHEA-S, T, SHBG were checked at the initial visit and at the end of the study. RESULTS: After 3 months of treatment, all but four of the 34 climacteric symptoms investigated showed a significant improvement. There were no significant changes noted in body weight. The average duration and flow of bleeding showed no significant changes during hormone replacement therapy (HRT). There were no serious adverse events related to treatment. CONCLUSION: The 17beta-estradiol/dydrogesterone combination HRT reduced effectively climacteric symptoms, showed no significant changes in endometrial thickness as determined by transvaginal ultrasonography and provided excellent cycle control.

Direct visual or blind insertion of the primary trocar.

BACKGROUND: We set out to assess the difference in complication rates between primary umbilical insertion by a blind trocar and insertion with an optical surgical obturator. METHODS: In a retrospective survey, we investigated the rate of severe complications by primary umbilical trocar entry. Of 1546 patients undergoing gynecological laparoscopies at a tertiary-care university hospital, 1000 cases were operated by blind umbilical insertion with a conventional primary trocar whereas 546 used an optical primary trocar. RESULTS: The rate of major complications during insertion of the primary trocar in the blind insertion group was five of 1000 (0.5%), whereas there were no major complications in the optical-guided insertion group (0.0%). CONCLUSIONS: In comparison with the blind insertion of a sharp trocar, optical guidance provides a safe and functional primary insertion method that allows to detect adhesions to be detected at an early stage, thus preventing injuries to the bowel and abdominal vessels.

[The CA-125 tumor marker in epithelial ovarian cancers of stage I]. / Der Tumormarker CA-125 bei epithelialen Ovarialkarzinomen des Stadium I.

A precondition for the early diagnosis of ovarian cancer by means of raised tumour marker levels is high sensitivity at an early stage of the disease. In this study the relationship of the levels of the tumour marker CA-125 to the variables age, grading and histological status was examined in 52 patients with verified FIGO stage I epithelial ovarian cancer. A liminal value of 35 U/ml was accepted and the patients were split into 2 groups according to whether the tumour marker exceeded this value or not. The survival probability was calculated for each group in order to gauge the prognostic significance of this serum marker. Although there was no statistically significant correlation between the CA-125 levels established preoperatively and the above-mentioned variables, in contrast to other studies we found a higher overall sensitivity of 62%. Of particular interest is the considerably higher sensitivity of CA-125 in the postmenopausal patients within our collective. The findings of this study suggest that marker-positive patients might have a poorer survival prognosis.

[Ambulatory hysteroscopy in evaluation of postmenopausal bleeding]. / Die ambulante Hysteroskopie in der Abklärung der postmenopausalen Blutung.

INTRODUCTION: Diagnostic hysteroscopy is the most precise procedure to evaluate diseases involving the uterine cavity. There is, however, only limited data concerning the use of hysteroscopy carried out as an outpatient procedure in patients with postmenopausal bleeding. MATERIALS AND METHODS: In this study we report on 360 postmenopausal patients with erratic bleeding, who were referred to our outpatient hysteroscopy clinic. 185 women had frank postmenopausal bleeding (PMB) and another 175 had abnormal uterine bleeding while taking hormone replacement therapy (AUB). The mean age was 57.9 years (range: 42-86). All hysteroscopies were performed using a standard 5-mm hysteroscope with a 30 degrees fore-oblique lens; the uterine cavity was generally distended with normal saline. RESULTS: Outpatient hysteroscopy was performed successfully in 339 patients (94.2%). In 166 cases (46.1%) cervical dilatation was necessary, and 138 required (38.3%) intracervical anaesthesia. Intrauterine pathology was diagnosed in 49.6% of cases, with endometrial polyps (20.9%) and fibroids (15.9%) being the most common abnormalities. While there was no difference in the incidence of intrauterine lesions between patients with AUB and those with PMB, endometrial carcinoma was more common in the latter group (PMB: n = 11 vs. AUB: n = 1; p < 0.002). CONCLUSION: Due to its high accuracy and patient acceptance, outpatient diagnostic hysteroscopy should become a first line investigation in postmenopausal patients with bleeding disorders.

[Technique and results of laparoscopic conservative organ-preserving myoma enucleation]. / Technik und Resultate der laparoskopisch konservativen, organerhaltenden Myomenukleation.

Myoma is one of the most common benign diseases of the female genital tract. The surgical management of this entity has been altered over the last years from complete hysterectomy to conservative enucleation of the myomas. We retrospectively compared our data concerning laparoscopic or open myomectomies. Over a period of 2 years, we operated 207 myomas in 102 patients. Of this collective, 69 (67.6%) were operated on laparoscopically and 33 (32.4%) via an open approach. In both groups, the median number of myomas was 2 (1-7). The mean diameter of the largest myoma was 5.1 +/- 2.4 cm (laparoscopy) and 6.2 +/- 2.6 cm (laparotomy), respectively. The additive diameter of myomas was 7.7 +/- 5.1 cm (laparoscopy) and 9.8 +/- 4.1 cm (laparotomy), respectively. There was no relevant difference between the groups in terms of operating time and blood loss. Four (3.9%) laparoscopies had to be converted to an open approach. In three cases (2.9%) a laparoscopically assisted enucleation had to be performed, requiring a mini-laparotomy 4 to 5 cm in length. We encountered no severe complications. Given appropriate indication, laparoscopic myomectomy is an easy-to-perform and minimally invasive technique with a low complication rate.
