Abstract
OBJECTIVES The main objective of this prospective observational study was to investigate the diagnostic performance of the p16/Ki-67 dual stain technique (DST) for detecting CIN 2+ in a LLETZ referral setting. Test performances were compared with HR-HPV testing and Pap cytology. METHODS All patients referred for a LLETZ procedure were candidates for participation in this trial. A total of 110 patients were enrolled between October 2016 and March 2017. From each participant, a cervical cytology sample was obtained before the onset of the LLETZ procedure. On each sample, the dual stain technique (Roche CINtec PLUS ® test), Pap cytology and an HPV DNA assay (identifying 17 different HPV types) were performed. RESULTS The overall disease prevalence of CIN 2+ was 56%. The mean age was 41 years, with 38% of patients being younger than 35 years. The overall sensitivity and specificity of the dual stain technique for detecting CIN 2+ was 94% (95% CI: 84.30-98.21%) and 58% (95% CI: 43.21-72.93%) respectively with a PPV of 74% (95% CI: 67.34-80.31%) and a NPV of 88% (95% CI: 72.48-94.90%). HR-HPV testing results in a similar sensitivity of 92% (95% CI: 82.17-97.33%) but considerable lower specificity of 21% (95% CI: 11.17-33.35%) compared to the dual stain technique. At an ASCUS or worse threshold, Pap cytology had the lowest sensitivity of 89% (95% CI 78.11-95.34%) compared to dual staining and HR-HPV testing. Specificity was better (48% with 95% CI of 33.29-62.81%) than that of HR-HPV testing but not as good as the DST. CONCLUSION p16/Ki-67 dual staining provides high sensitivity and improved specificity compared to HR-HPV testing and Pap cytology for detecting CIN 2+, making it an interesting tool for identifying relevant disease in patients referred for a LLETZ procedure.

Abstract
OBJECTIVE To evaluate whether the dimensions of the cones removed during large loop excision of the transformation zone have decreased over time. Secondly, whether these changes were associated with a lower risk of obstetrical harms on a subsequent pregnancy. STUDY DESIGN A retrospective matched cohort study was performed in a tertiary referral unit in Belgium. A total of 97 women were identified from a database of women who underwent excisional treatment for cervical precancer between January 1st, 2004 and December 31st, 2012, and delivered before December 31st, 2014. The control group consisted of 120 non-treated women who had no history of cervical intra-epithelial neoplasia. Data on smoking status; gestational age at delivery; number of conisations; time interval between treatment and pregnancy; dimensions of the cone; severity of the lesion; and the extra resection of endocervical tissue were collected. These data were compared with those from a previous similar study at the University Hospital of Leuven in 2009, which database we enriched with information on the cone dimensions. Main outcome variables were gestational age at delivery, birthweight and neonatal condition at birth. RESULTS Only a significant lower birthweight could be found in the treated group compared to the control group (3364g [95% CI 3094-3290] versus 3364g [95% CI 3253-3475], P=0.023). The current study showed no increase in preterm birth rate after conisation and no relationship between volume or depth of the cone and preterm birth could be found. Over the period 1999-2014, a significant decrease in all dimensions was observed: on average -0.3mm, -0.3mm, -0.4mm and -132mm3 per year, for the depth, anteroposterior and transverse diameter and the volume, respectively. CONCLUSIONS Our two successive studies showed a significant trend towards smaller cones which was accompanied by a decrease in preterm birth after excisional treatment. The clinician could limit the size of the cone to avoid obstetrical harms, but needs to be aware of the oncological safety as well.

Abstract
BACKGROUND Early effects of HPV (human papillomavirus) vaccination are reflected by changes observable in young women attending cervical cancer screening. SUBJECT AND METHODS The SEHIB study included HPV geno-typing of ∼6000 continuous and 650 pathological cervical cell specimen as well as biopsies, collected from women in Belgium in 2010-2014. Data were linked to vaccination status. RESULTS HPV vaccination offered protection among women aged <30years against infection with HPV16 (vaccine effectiveness [VE]=67%, 95% CI: 48-79%), HPV18 (VE=93%, 95% CI: 52-99%), and high-risk HPV (VE=16%, 95% CI: 2-29%). Vaccination protected also against cytological lesions. Vaccination protected against histologically confirmed lesions: significantly lower absolute risks of CIN1+ (risk difference [RD]=-1.6%, 95% CI: -2.6% to -0.7%) and CIN3+ associated with HPV16/18 (RD=-0.3%, 95% CI -0.6% to -0.1%). Vaccine effectiveness decreased with age. Protection against HPV16 and 18 infection was significant in all age groups, however no protection was observed against cytological lesions associated with these types in age-group 25-29. CONCLUSION The SEHIB study demonstrates the effectiveness of HPV vaccination in Belgian young women in particular in age group 18-19. Declining effectiveness with increasing age may be explained by higher tendency of women already exposed to infection to get the vaccine.

Abstract
Abstract
OBJECTIVE: The levonorgestrel-intrauterine device (LNG-IUD) is a widely used contraceptive method. It is not clear if LNG-IUD users are more likely to develop breast cancer. Breast cancer growth through the estrogen and/or the human epidermal growth factor receptor 2 (HER2) pathway could be influenced by a continuous low systemic dose of levonorgestrel. In this study, we compare breast cancer characteristics and the receptor expression of estrogen (ER), progesterone (PR) and HER2 in women with and without a LNG- IUD at the time of diagnosis.
METHODS: In this retrospective, observational study, we included 2599 consecutive breast cancer patients who were younger than 55 years at diagnosis and treated between 2000 and 2014 in the University Hospitals Leuven for a primary invasive, non-metastatic tumor. The non LNG-IUD group was matched by age and parity at diagnosis. ER, PR and HER2 status were reported according to ASCO/CAP guidelines. The Chi-square test was used to compare receptor status between groups. All tests were two-sided, and a 5% significance level was assumed. An additional analysis was performed to detect the occurrence of HER 2 expression with or without intake of oral contraception by diagnosis in the control group.
RESULTS: 366 LNG-IUD users and 2233 women without a LNG-IUD were included. Compared to the control group, the LNG-IUD users had a lower Nottingham prognostic index (4.2 vs 4.4; p=0.048), more PR expression (79.2% vs 73.4%; p=0.021) but less HER2 expression (11.6% vs 17.2%; p=0.009). A significant higher rate of ER+PR+HER2- was observed in the LNG-IUD group (63.26 % vs 73.46%; p<0.001). These differences in receptor expression were mainly observed in the age group 45-49 years at diagnosis. Additionally, a trend of more HER2 positivity associated with oral contraceptive use was noticed in the control group.
CONCLUSION: We found in a breast cancer population, matched for age and parity, significant differences in the PR and HER2 expression according to use of LNG-IUD at time of diagnosis. ER positive, PR positive and HER2 negative breast cancers are more frequently seen in LNG-IUD users. There is a trend of less HER 2 positivity in LNG-IUD users and it is more common seen in oral contraception users.

Abstract
INTRODUCTION Endometrial cancer (EC) can affect sexual functioning based on anatomical, physiological, psychological, and relational mechanisms. AIM The aim of this study was to prospectively investigate sexual adjustment of women with EC during a follow-up period of 2 years after surgical treatment and to compare the results with women who underwent a hysterectomy for a benign gynecological condition and healthy control women. METHODS/MAIN OUTCOME MEASURES In this prospective controlled study, participants completed the Short Sexual Functioning Scale, Specific Sexual Problems Questionnaire, Beck Depression Inventory Scale, World Health Organization-5 Well-being Scale, and Dyadic Adjustment Scale to assess various aspects of sexual and psychosocial functioning before undergoing a hysterectomy and 6 months, 1 year, and 2 years after surgery. RESULTS Eighty-four women with EC, 84 women with a benign gynecological condition, and 84 healthy controls completed the survey. In EC survivors, no differences were found in sexual functioning during prospective analyses. In comparison with women with a benign gynecological condition, significantly more EC patients reported entry dyspareunia 1 year after surgical treatment. Moreover, compared with healthy women, pre- and postoperatively, significantly more EC patients reported sexual dysfunctions, including sexual desire dysfunction, arousal dysfunction, entry dyspareunia, and a reduced intensity of orgasm. Furthermore, compared with healthy controls, EC patients reported significantly lower overall well-being 1 year after surgical treatment. Nevertheless, consensus in the partner relationship was significantly higher in EC patients compared with healthy controls. Moreover, before treatment, quality of partner relationship was negatively associated with sexual arousal dysfunction and orgasm dysfunction. CONCLUSIONS In EC patients, no differences were found in sexual functioning when prospectively comparing the situation before surgery with the situation after surgery. However, when compared with healthy controls, EC patients are at high risk for sexual dysfunctions, both before and after surgical treatment.

Abstract
BACKGROUND Three-dimensional (3D) roadmap is a recently developed imaging technique used to guide diagnostic and interventional catheter-directed procedures and mainly evaluated for neurovascular procedures. Few data with regard to efficacy and radiation dose are currently available in literature. PURPOSE To evaluate the use of 3D roadmap technique as compared with the conventional two-dimensional (2D) roadmap for uterine artery catheterization and embolization during uterine fibroid embolization and assess the potential impact on radiation dose, contrast load, and total procedure time. MATERIAL AND METHODS In this prospective study, 40 patients were randomly assigned to the 2D or 3D roadmap technique for uterine artery catheterization. Demographic data, specifically the patient's age, weight, height, pelvic circumference, and total uterine and fibroid volume were recorded. Exposure parameters, contrast load, and procedure time were recorded and organ doses for ovaries and uterus were calculated. RESULTS Demographic data did not differ between the groups. Catheterization and embolization of both uterine arteries were feasible in all patients, although in one patient in the 3D group, a focal dissection of the proximal uterine artery occurred. No significant difference in estimated ovarian dose was found in the 3D versus 2D group (P = 0.07). Total procedure time was shorter in the 2D group (P = 0.01) and no difference in total contrast load was seen (P = 0.17). CONCLUSION Both roadmap techniques are effective imaging-guided tools for uterine artery catheterization, without difference in terms of radiation exposure or contrast load. The total procedure time is shorter in the 2D group.

Abstract
Abstract
During the last years the introduction of an electronic situation report system in nuclear power plants has been intensively discussed in the working group emergency staff coordinators of the VGB (‘Verband der Großkraftwerksbetreiber’). In parallel, many federal state authorities as well as the German Ministry of the Environment already successfully started to operate such a system. Based on a solution developed for the ministry for environment Baden-Württemberg, the specific requirements are adapted and extended for the operation in a nuclear power plant. The most important features are easy handling, open interfaces to the systems of the authorities, and flexibility for functional extensions. The advantages recognized after the first test stages led the nuclear power plants Biblis and Neckarwestheim to the decision to introduce such a system at the plant site. First progress and experience gained are reported from the perspective of the crisis management group of the power plant.

Abstract
INTRODUCTION Vulvectomy is an intrusive treatment option for women with vulvar malignancy that theoretically may affect sexual function. AIM This study aims to provide a comprehensive review of the literature on the impact of surgical treatment for vulvar malignancy on sexual functioning, overall quality of life, and partner relationship. METHODS Systematic search of the medical literature on PubMed, PsycINFO, Cochrane database, Google Scholar and Embase using a number of related terms including vulvar malignancy, vulvar cancer, vulva cancer, vulval cancer, vulvectomy, sexual function, partner relation, quality of life, and psychological functioning. MAIN OUTCOME MEASURE Measures and indicators of sexual function, overall quality of life, and partner relationship following vulvectomy for vulvar malignancy. RESULTS There is evidence that women who undergo surgical treatment for vulvar cancer or vulvar intraepithelial neoplasia are at high risk for sexual dysfunctions, dissatisfaction with partner relationship, and psychological difficulties. Factors associated with posttreatment sexual dysfunction include patient's increased age, poor overall well-being, history of depression, anxiety, and excision size of vulvar malignancy. CONCLUSIONS Surgical treatment of vulvar cancer has a negative impact on sexual function, quality of life, and satisfaction with partner relationship. However, hitherto only little research effort has been directed to postoperative sexual well-being in vulvar cancer survivors. There is a need for more methodological sound prospective studies that explore sexual function, quality of life, and partner relationship and its predictors over time in vulvar cancer patients.

Abstract
INTRODUCTION There has been little research published on the impact of intrauterine contraceptive (IUC) methods on sexual functioning. AIMS This study aimed: (i) to assess different aspects of sexual functioning, including the prevalence of sexual dysfunction in women using a levonorgestrel intrauterine system (LNG-IUS); (ii) to compare this prevalence with that among copper-releasing intrauterine device (Cu-IUD) users; and (iii) to identify the relationship between psychological variables and sexual functioning in women using one of the aforementioned IUCs. METHODS In a multicenter cross-sectional study, 845 women with an IUC were invited to fill out a questionnaire. The latter was returned by 402 (48%) of them: 353 women were LNG-IUS users (88%) and 49 were Cu-IUD users (12%). The questions asked pertained to depression, well-being, marital relation quality, and sexual functioning. MAIN OUTCOME MEASURES Sexual functioning was measured with the short sexual functioning scale. RESULTS One-third of LNG-IUS users (33%) reported a sexual dysfunction. Of those, 20% reported an increased sexual desire, 25% a decreased sexual desire, 5% arousal problems, and 8% orgasm problems. Women using a LNG-IUS did not differ significantly in distribution, type, or prevalence (32.9% vs. 36.7%) of sexual dysfunction, nor in depressive symptoms (Beck Depression Inventory score; 4.7 vs. 3.9; P = 0.33), general well-being (WHO-5 well-being scale score; 16.8 vs. 17.7; P = 0.170), or partner relationship quality (Dyadic Adjustment Scale score; 107 vs. 108; P = 0.74) compared to Cu-IUD users. Overall, the perceived influence of IUCs on sexual functioning was in the lower range and did not differentiate LNG-IUS greatly from Cu-IUD-users. CONCLUSION Women using a LNG-IUS do not differ from those wearing a Cu-IUD with regard to psychological and sexual functioning. The perceived impact of IUD use on sexuality should not be overestimated.

Abstract
BACKGROUND Aggressive angiomyxoma (AA) is a rare vulvovaginal mesenchymal neoplasm with a marked tendency to local recurrence but which usually does not metastasize. CASE REPORT We describe a case of AA in the left labium majus pudendi in a 47-year-old woman who underwent incomplete surgical excision. Follow-up 2years later revealed no recurrence. CONCLUSION In the past, most authors advocated wide excision even if genitourinary and digestive tract resection were necessary. These days, a less radical surgery is recommended, but the significance of hormonal treatment and/or radiation therapy is not clear yet. Further investigation is necessary.

Abstract
Antipapillomavirus vaccination of young girls before their first sexual encounter is now a common practice. However, this prophylactive measure could also be extended to older patients. The HPV infection is indeed not limited to teenagers even if the highest incidence rate is noticed between the age of 18 and 30, it can also be found in older women. These older women show a sustained prevalence due to the longer persistence of the infection. This is clearly illustrated by the incidence of cervical cancer after the age of 50. Moreover, phase 3 studies in large unselected populations have shown the effectiveness of HPV vaccination in patients who had previously been infected by HPV (and got cured of it) as well as with patients who had never had any papillomavirus contact. Actually, less than 1 % of women who present simultaneously a HPV 16 and a HPV 18 infection will not derive any benefit from a HPV vaccination. Therefore, it seems logical to positively consider a HPV prophylaxis in patients who are above the age of 25 and who do not present any papillomavirus induced cervical lesion.

Abstract
OBJECTIVE Hysterectomy with concomitant cervical intraepithelial neoplasia (CIN), is often considered a definitive treatment for CIN, but development of subsequent vaginal intraepithelial neoplasia (VAIN) is known to range from 0.9% to 6.8%. STUDY DESIGN In a retrospective analysis of 3030 women with CIN2+ without history of VAIN in the University Hospital Gasthuisberg, Leuven, Belgium, from January 1989 until December 2003, we identified 125 women who underwent a hysterectomy within 6 months after diagnosis of CIN2+ and reviewed their postoperative Papanicolaou smears. RESULTS Thirty-one patients (24.8%) were lost to follow-up. Seven of the 94 women in the follow-up group (7.4%) developed VAIN2+, of which 2 were invasive vaginal cancers. Median interval between hysterectomy and diagnosis of VAIN2+ was 35 months (5-103 months). Women with recurrence were significantly older (P = .003). CONCLUSION Hysterectomy may not be considered as a definitive therapy for CIN2+ because the incidence rate of subsequent VAIN2+ is as high as 7.4%.

Abstract
OBJECTIVES The aim of this study was to examine the accuracy of the presence of high-risk human papillomavirus (HR-HPV) DNA (HR-HPV DNA test) postconisation as prediction of recurrent or residual cervical intraepithelial neoplasia (CIN) after treatment of high-grade cervical intraepithelial lesions (CIN2+) in a prospective study and to compare this with follow-up cytology and the marginal status of the excised tissue. DESIGN Prospective follow-up study. SETTING Unselected women presenting at colposcopy clinic of University Hospital Gasthuisberg, Leuven. POPULATION Seventy-two women treated with conisation for CIN2 or CIN3. METHODS Women were followed by HR-HPV DNA test (Hybrid Capture II test of Digene) every 3 to 6 months. The same vial was used for cytology and the HR-HPV DNA test (SurePath). All women were further followed by colposcopy and cytology for 24 months at 6-month intervals. The outcome of the study was presence of >CIN2, proven with colposcopy-directed biopsy occurring within 24 months after treatment. HR-HPV status was correlated with recurrent or residual CIN2+. MAIN OUTCOME MEASURES Sensitivity, specificity, predictive values and diagnostic odds ratios to predict treatment failure or cure were computed for HR-HPV testing, marginal status and follow-up cytology. HR-HPV status was also correlated with section margins postconisation and with the first cervical smear. RESULTS In 6 of the 72 treated women (8%), residual or recurrent CIN occurred. Women with recurrence were significantly older than women without a recurrence (51.5 +/- 9.6 versus 39.8 +/- 12.2 years, P= 0.007). All six women with recurrence were HR-HPV positive, four had a positive follow-up smear (>or=atypical squamous cells of uncertain significance = ASCUS+) and only two had involved section margins. Among the 66 cured women, 15 were HR-HPV positive, 6 had an abnormal smear and 12 had positive section margins. Sensitivity of cytology, positive section margins and HR-HPV DNA positivity was 66.7, 33.3 and 100% to predict treatment failure. Specificity of the three tests was, respectively, 90.9, 81.8 and 77.3%. Women with HR-HPV DNA at 3 to 6 months showed recurrent or residual CIN in 15% (2/13) if they had normal follow-up Pap smears and in 50% (4/8) if they had abnormal Pap smears. Margin status was not statistically significantly associated with human papillomavirus status. CONCLUSION Persistence or clearance of HR-HPV DNA is an early valid prognostic marker of failure or cure after treatment for CIN2+ and is more accurate than cytology or section margin status at the time of conisation. The absence of HR-HPV DNA has a 100% negative predictive value. Higher age at conisation may be a previously unrecognised risk factor for recurrence.

Abstract
The use of the carbon dioxide (CO2) laser for laparoscopic enterocele repair was evaluated in four women with an enterocele as the only pathology. Three women had a large enterocele after earlier hysterectomy, and one young woman had a congenital enterocele. The technique consists of vaporizing the peritoneum of the enterocele; however, it is important first to delineate carefully the lesion's circumference because of the strong retraction during vaporization. Subsequently, a posterior culdotomy is performed taking care to restore the horizontal position of the upper vaginal axis by shortening the uterosacral ligaments, which are sutured together on the midline and the posterior vaginal wall. The (CO2) laser has the advantage that the superficial vaporization it produces is rapid (<5 min), safe, and completely bloodless. The shrinking during vaporization facilitates subsequent repair. Postoperative morbidity and recovery were uneventful for all patients. The (CO2) laser seems to have some advantages over sharp endoscopic resection of enteroceles. The relative simplicity of technique and the low postoperative morbidity suggest that endoscopy could become routine in pelvic floor surgery, improving diagnosis and complementing vaginal surgery while avoiding laparotomy.

Abstract
After a critical discussion with antiquated and actual problems to the electroconvulsive therapy the problem-important peculiarities of progress and treatment of the psychosis in the higher age are exhibited. In search of satisfactoring solutions we used Dexamethazon as a supplemental premedication in the electroconvulsive therapy and by this way we found out a remarkable minimize of complications which allowed to put in more frequently the electroconvulsive therapy during the psychosis in the higher age. This leads to a general optimation of prognosis of the late psychical diseases. Beside the method itself the urgency of indications and exclusion of standards are described in the same way, also there are shown the few complications in comparison with the successes of therapy of 2010 electricalconvulsive therapies from 433 patients.

Abstract
We have evaluated a new assay for the specific determination of pancreatic (P) isoamylase, the principle being based on a synergistic inhibitory effect of two monoclonal antibodies directed towards salivary (S) amylase. After 3 min incubation, activities were determined with maltoheptaoside-PNP as substrate on a Hitachi 705 analyzer at 25, 30 and 37 degrees C, respectively. Coefficients of variation ranged from 0.6 to 5.4% for within-run and 2.1 to 9.9% for day-to-day precision. Linearity held up to 1200 U/L (25 degrees C) and 2300 U/L (37 degrees C). Comparison of the new method with the wheat germ inhibitor technique showed an excellent correlation, with coefficients ranging from 0.990 to 1.00. Using purified P- and S-amylase we observed no inhibiting cross-reactivity of the antibodies with the P-isoenzyme, but an incomplete blockage of S-amylase: residual activity was approximately 2% at 25 and 30 degrees C, and 2.5% at 37 degrees C. The distribution pattern of P-, S- and total amylase activity in serum of healthy subjects was only slightly skewed to the right. We found neither an influence of sex nor of age on the reference ranges. In random urine samples, distribution of activities was strongly skewed. However, if the activity was related to the urinary creatinine concentration, an approximately normal distribution was obtained, allowing, as in serum, the establishment of upper and lower reference values.

Abstract
The determination of alpha-amylase activity using an ethylidene-blocked 4-nitrophenyl-maltoheptaoside (EPS) has been evaluated in five laboratories on eight different analysers at 25 degrees C, 30 degrees C and 37 degrees C. The protecting ethylidene group inhibits hydrolysis at the non-reducing end of the substrate molecule by the auxiliary enzyme, alpha-glucosidase. The combined reagent is therefore stable for at least 10 days at 2-8 degrees C. HEPES is used, because the molar absorbance of 4-nitrophenol is independent of temperature in the presence of this buffer. Compared with the method using unprotected substrate 4-nitrophenyl-alpha-D-maltoheptaoside (4NP-G7), the present method is equal or better with respect to the imprecision, linearity and interlaboratory transferability of results in human and control sera. Since the protected and unprotected substrates differ in their turnover rate, the new assay yields activities which differ from those of the 4-nitrophenyl-alpha-D-maltoheptaoside method. Based on the homogeneous results obtained in method comparisons between EPS and 4-nitrophenyl-alpha-D-maltoheptaoside, and in order to maintain the 4-nitrophenyl-alpha-D-maltoheptaoside reference values, a conversion factor was derived to eliminate the above differences: activityEPS x 2.50 = activity4NP-G7. The temperature and instrument independence of this relationship was demonstrated in a total of 720 human sera and plasmas.

Abstract
The selective multitest Boehringer Mannheim/Hitachi 704 analysis system was examined according to the ECCLS guidelines in a multicentre evaluation involving four laboratories. Ten routine parameters, covering most of the application settings of the instrument, were measured in the respective laboratory at temperatures 25, 30 or 37 degrees C. The trial lasted four months and gave more than 40,000 data. It yielded the following results: 1. Within the four laboratories the mean coefficients of variation for three control sera at different concentrations were found to be equal to or better than 1.6% for the within-run imprecision and 2.8% or better for the between-day imprecision. 2. No drift was observed during eight hours. 3. Because of the high linear measuring range a re-run analysis was seldom necessary. 4. Sample-related carry-over was not seen. Reagent-dependent carry-over was measured from cholesterol to uric acid and from triacylglycerols to lipase. Through modification of the cholesterol and triacylglycerol reagents, the carry-over effect was practically eliminated. 5. The recovery of the assigned values of control sera showed average values between 99 and 104%. For bilirubin, creatinine, creatine kinase and alanine aminotransferase some control sera showed deviations greater than 10%. 6. In all cases, regression analysis of the results obtained in comparisons of the present instrument with the Hitachi 705 or 737 yielded slopes close to unity with extreme values of 0.95 and 1.06. 7. During the entire evaluation period there was no malfunction or breakdown of the instruments. The evaluators came to the conclusion that the analytical performance as well as the reliability and practicability of the Hitachi 704 can be rated as excellent.

Abstract
A 25-year-old woman with a congenital uterine arteriovenous malformation had a long history of repeated excessive vaginal bleeding. She was successfully treated with transarterial embolization. She had normal menstrual periods for 6 months and subsequently conceived. She was delivered of a normally grown baby at 35 weeks. To the best of our knowledge, this is the third pregnancy described after successful embolization of an arteriovenous malformation.

Abstract
We describe a simple and rapid method for measuring pancreatic and salivary type amylases using the Hitachi 705 analyser. The determination is based on the inhibition of salivary amylase using an inhibitor isolated from wheat germ. The precision of the proposed method was very good: within-day precision varied from 0.4 to 2.5% (CV) and day-to-day precision from 2.2 to 3.7% (CV). The new application correlated well with another commercially available inhibition method. As the standardization is very stable and the assay procedure exactly the same as for the total amylase assay, the proposed method is suitable for routine isoamylase determination. Reference values for pancreatic and salivary amylase activities are presented.

Abstract
Five methods for the quantification of low-density-lipoprotein cholesterol were compared: ultracentrifugation, electrophoresis, precipitation with polyvinyl sulfate or heparin, and an indirect calculation procedure (Friedewald formula). Excellent agreement of results was obtained with all procedures for 49 of 51 sera. Discrepancies were as much as 1.69 g/L for the remaining two cases, which contained appreciable amounts of "floating" beta-cholesterol as detected with a combination of ultracentrifugation and electrophoresis.

Abstract
This paper is dedicated to the honour of Prof. Dr. Erich Sternberg. The diagnostical strategy of well-known specialists for the Morbus Pick and Morbus Alzheimer is considered. As a result of our own experiences and analyses the psychopathological factors are assigned to the following groups: change of vitality; change of personality; reversible organic psychoses; fuzzy brain-local symptoms; development of dementia. For these groups growth curves are given for which the analytic description by a special type of a differential equation, is used. The different behaviour of the development of the dementia to the Morbus Pick and Morbus Alzheimer is found.

Abstract
Investigations on the photodynamic action of psoralens with DNA were performed, using experimental techniques of fluorescence lifetime and NMR-CIDNP, as well as SCF-MO and CNDO molecular orbital calculations. It has been shown that the formation of a biradical through the triplet state is the decisive step for psoralen dimer formation, as well as for cyclobutane addition with thymine, while singlet oxygen production is responsible for enzyme inactivation (e.g., lysozyme and trypsin). The molecular orbital calculations, in agreement with experimental results, indicate that the differences in biological effectivity of different psoralens are based on variations in triplet formation probability.

Abstract
The wave model of endogenous psychoses constructed by us is based on special properties of the envelopes of arterial pulse waves. It has been tested and used by the Bechterev Institute in Leningrad. We could confirm us that all examined patients are classified into the right class of psychosis solely by their measurement vector of the envelope curve. Also statements about the progress of the psychosis are possible.

Abstract
After the successful classification of endogenous psychoses only by a vector of measuring dates of covering curves of the arterial pulse waves was tested, whether the concrete state of activity of the generally activating reticular system observed in this case may be described also according to the peculiarity of centrally regulated variations of the cardiac rhythm. Using the vectors of the measuring values of these regulation influences we also got a rate of correct classification of endogenous psychoses of about 80%.

Abstract
It belongs to the definition of chronic alcoholism that also clinically established lesions of the organs can be proved. As to the nervous system the case in question are multilocular defects which concern the central and peripheral nervous system. The local accentuation, the developmental speed and the intensiveness of the alcoholic defect of the cellular metabolism lead to different courses. The suggestion of their individuality must at the same time take into consideration the character of chronic alcoholism which on principle affects the whole nervous system.

Abstract
The envelope curves of arterial pulse waves are carries of information about the central circulatory and respiratory regulation. Using a discriminence analysis, the mean width of the wave peak of this curve appears as a characteristic feature of the activity form of the generally activating reticular system which is changed in endogenous depressions. By means of this feature, it is possible to distinguish patients with endogenous depression from healthy test persons without using psychopathological findings.

Abstract
Depressive psychoses are accompanied by vegetative disorders. Third-order blood-pressure waves are an expression of vasomotor rhythms which through diencephalic and limbic structures tend to adjust the blood pressure to the respective overall psychovegetative situation. In the case of depressions with an axious increase of impulse, statistical evidence was obtained, within the framework of clinical improvement, for a correlation between a decreasing score of depression and an increasing frequency of third-order waves. The same central trends of these quantities suggest that both of them are different manifestations of a common functional disorder in the limbic system and diencephalon.
