Abstract
Southern blot analysis and the polymerase chain reaction (PCR) are powerful tools for detecting clonal antigen receptor gene rearrangements. However, a number of limitations restrict the predictive value of the results obtained by these techniques as they are commonly used. We describe a new method, automated high-resolution PCR fragment analysis, that can partially overcome many of the limitations of analyzing the T-cell receptor (TCR) gamma-chain gene. Analysis of TCR-gamma is performed using PCR with four sets of primers, previously described by others, specific for all variable (V) and joining (J) regions of the TCR gamma-chain gene. In addition, the four V region primers are 5' end-labeled with a fluorescent compound, 5-carboxyfluorescein. After amplification, the labeled PCR products are separated with an automated sequencing system, ABI 373 (Applied Biosystems, Weiterstadt, Germany). With the help of the Gene-Scan software ABI 672 (Applied Biosystems) and fluorescent-labeled DNA length markers, the exact size of each peak can be displayed and analyzed. The resolution of this method allows separation of PCR products differing in length by as little as 1 bp. Semiquantitative estimation of specific clones also can be performed. Infiltrate-specific gene rearrangement patterns can be identified and recognized in different tissue specimens at the time of diagnosis or in subsequent biopsy specimens. We conclude that automated high-resolution PCR fragment analysis allows more accurate and convenient analysis of the TCR gamma-chain gene.

Abstract
Recently, various conservative regimens for the treatment of cervical pregnancy have been introduced to preserve fertility in young women, with methotrexate being one of the most widely used drugs. The success of conservative treatment depends on early preoperative diagnosis. We report three cases of first trimester cervical pregnancy, successfully treated by curettage to evacuate the conceptus, followed by local prostaglandin instillation to prevent severe haemorrhage. In one patient, intra-amniotic instillation of hyperosmolar glucose was necessary to terminate fetal cardiac activity. beta-Human chorionic gonadotrophin returned to normal within 3 weeks in one patient and within 7 weeks in another, both of whom became pregnant again within 1 year, resulting in term deliveries. The third patient was lost to follow-up after 1 week. The advantage of prostaglandin and curettage is the absence of major side-effects to the mother or the fetus of a subsequent pregnancy. The management strategies used in the treatment of cervical pregnancies and the results obtained since the introduction of methotrexate in 1989 are discussed in the context of previously published literature. The incidence of subsequent pregnancies among women treated medically versus women treated surgically is reported.

Abstract
Differentiation of a cutaneous lymphoma from a reactive lymphoid infiltrate is a demanding challenge for the pathologist. In this retrospective study we examined 24 paraffin-embedded tissue samples from lesions diagnosed as lymphomas and 7 control samples of skin affected by benign changes and with pronounced lymphoid infiltrates for clonal rearrangement of the gamma T-cell-receptor. Using PCR technology we demonstrated clonality in 22 cases of lymphoma (92%). Thus, the primer combination used in this study covering the four main groups (I-IV) of the variable region of the gamma T-cell receptor gene allows high sensitivity. No clonality was demonstrable in any of the 7 control cases. This study demonstrates the growing importance of PCR technology for the diagnosis of lymphoma.

Abstract
The purpose of the study was to evaluate the effects of drug therapy on the throphoblast and on the tubal wall when protaglandin F2 alpha (PGF2 alpha) was administered in cases of tubal pregnancies. 42 patients were divided into two groups: women of group I (n = 30) were secondarily treated by surgery because of raising serum HCG levels. Group II (n = 12) consisted of patients who were operated on because of acute symptoms (abdominal pains, intraabdominal haemorrhage), despite already failing HCG values. In group I in 66% (n = 20) of the histological specimens an intact (vital) trophoblast was found. Five cases (17%) showed partly necrotic gestational tissue, whereas in another five cases (17%) the whole trophoblast was necrotic. In patients of group II all ectopic pregnancies showed histological signs of necrosis. In the histopathology of the Fallopian tubes no signs of trophic regression could be found. However, ten out of 22 cases showed ruptured tubal pregnancies. In this analysis we could show that the instillation of PGF2a electively destroys the ectopic trophoblast and does not exercise any necrotic action on the tubal wall.

Abstract
Complications of percutaneous umbilical blood samplings and intravascular transfusions can be detected rapidly, easily and efficiently by Doppler ultrasound and therefore the operator can react as early as possible. In addition to real-time sonography Doppler ultrasound allows for assessment of haemodynamical changes due to intravascular transfusions both on the venous and arterial side of umbilical perfusion. Because of immediate recognition of bradycardia and other fetal cardiac frequency alterations as well as increase of resistance to blood flow on the arterial side the operator can react promptly. On the venous side correct application of transfused volume is monitored continuously by changes of flow velocity waveforms during injection and allows to assess dislocation of the needle.

Abstract
Concentrations of beta-human chorionic gonadotrophin (HCG) of 2500 IU/l are generally considered to be maximal for successful drug therapy of tubal pregnancies [instillation of prostaglandin-F2 alpha (PGF2 alpha) or hyperosmolar glucose]. The purpose of our study was to ascertain if there was an association between the significantly higher failure rates above this threshold value and the histologically determined anatomopathological substratum. We therefore evaluated the impact of trophoblast penetration through the basal membrane of the Fallopian tube on the efficacy of drug therapy. Pre-operative serum beta-HCG concentrations were compared with the histologically determined trophoblast penetration, distinguishing between ectopic pregnancies with intra-luminal growths up to the myosalpinx, and those with extra-luminal growths going beyond the basal membrane and penetrating the myosalpinx. Basic data were obtained from a group of patients who received primary surgical treatment but it had never been the intention for them to receive drug therapy (independently of their initial beta-HCG values; group I, n = 43). These reference data were compared with the findings in preparations from another group of patients obtained during secondary surgical intervention, performed to achieve final cure of tubal pregnancy after failure of primary PGF2 alpha instillation (group II, n = 30). Group I patients showed a significantly higher rate of intra-luminal trophoblast growths (P = 0.0001) at beta-HCG values < 2500 IU/l; above this threshold value, extra-lumina spread was found significantly more often (P = 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
beta-HCG (human chorionic gonadotropin) values of over 2500 I.U./l are associated with higher failure rates for therapy with prostaglandin F2 alpha in tubal pregnancies. The purpose of our study was to ascertain if the 2500 I.U./l limit correlates with histopathology. We therefore compared the pre-operative beta-HCG-values and intraluminal and extraluminal trophoblast growth in tubal pregnancy. Purely intraluminal trophoblast was significantly more frequent in patients of group I (beta-HCG < 2500 I.U./l), while group II patients (beta-HCG > 2500 I.U./l) almost exclusively had extraluminal growth (P = 0.0045). Since the efficacy of prostaglandin F2 alpha therapy depends on intact tubal musculature the correlation of the beta-HCG threshold level with histopathologic findings may explain the high failure rate in patients with beta-HCG values above 2500 I.U./l.

Abstract
The bad prognosis of primary Fallopian tube carcinoma (FTC) is mostly ascribed to early lymphogenous metastasis. Yet, there is a lack of information on the tumor size at which lymph node metastasis must be expected to occur. Our study was therefore designed to correlate the anatomopathologic substratum and the histologic results with the lymph node status. Data were obtained from 21 women who received primary surgery, during which additional total pelvic and para-aortic lymphadenectomy was performed as well. The "surgical" staging was compared to the final clinical staging after histologic inspection of the lymph nodes according to the FIGO classification. Lymph node metastases never occurred as long as the tumor was confined to the tube (stage I). Lymphogenous dissemination set in only after further, local expansion of the tumor, involving the ovaries, the peritoneum, or the uterus (surgical stage II); 3 of the 7 patients of surgical stage II had to be reclassified to stage III because of manifest lymph node metastases. After the onset of intra-abdominal or general metastasis (stage IV), lymph node metastases occurred significantly more often (P = 0.048). Due to the specific lymphatic drainage, lymphogenous metastasis must be expected to spread as far as to the para-aortic region even in the early stages. Highly differentiated tumors (G I) do not disseminate into the lymphatic system, not even in advanced stages, whereas anaplastic tumors (G II and III) metastasize relatively early. As soon as metastasis has occurred, prognosis of life diminishes markedly, but not significantly (49 versus 24 months, P = 0.19). Correct FTC-staging is obtained only on the basis of pelvic and para-aortic lymphadenectomy.

Abstract
HELLP syndrome (haemolysis, elevated liver function tests and low platelets) is a multiorganic disease and has been described in combination with pre-eclampsia/eclampsia, but even without symptoms of gestosis. There are signs, that HELLP syndrome represents an "acute status of autoimmunity". Since immune mechanisms play a fundamental role together with other factors in the development of type I diabetes mellitus, a combination of autoimmune reactions could explain the development of type I diabetes during an altered immune status. We report on the course of a pregnancy complicated by HELLP syndrome, which developed type I diabetes mellitus in the same pregnancy. A subsequent pregnancy with adequate diabetes therapy was uncomplicated and without recurrence of HELLP syndrome.

Abstract
The use of diode-array detection allows the non-destructive identification of tryptophan and tyrosine residues in complex peptide mixtures separated by capillary electrophoresis. Second-order derivative spectra of both amino acids show significant differences while zero-order spectra are overlapping to a great extent. A mixture of peptides containing tryptophan and/or tyrosine residues was used to evaluate this method. Tryptic peptide maps of carbonic anhydrase and of the bacterial chaperonin protein GroEL, and of an autodigest of trypsin were characterized for tryptophan- and tyrosine-containing peptides. Automated spectra library search was performed successfully.

Abstract
A 72-year old lady suffering from coronary heart disease was admitted with acute abdominal pain. Laparoscopy was performed and revealed perforation of a duodenal ulcer. The surgeon decided to suture the perforation via laparoscope. After an uncomplicated start he had to finish the laparoscopic procedure because of a massive hypercapnia and a developing subcutaneous emphysema. Laparotomy showed an iatrogenic perforation of the right diaphragm. A chest drain was inserted; after suturing of the perforated ulcer the abdomen was closed. The further hospital stay was uneventful. The possible causes for the increasing hypercapnia are discussed. We suggest close monitoring of patients during laparoscopy including capnometry and the anaesthesist should be aware of rare complications.

Abstract
OBJECTIVE To evaluate retrospectively the importance of invasion beyond the basement membrane on overall survival in Fallopian tube carcinoma and its influence on the necessity of postoperative adjuvant therapy (stage 0 vs. stage I). DESIGN In a nationwide analysis the data of 51 patients were evaluated. The participating departments provided the study center with histologic specimens. A re-staging was done according to the FIGO-classification for Fallopian tube carcinomas. Stage 0 patients received no further postoperative therapy, in stage I patients were divided in 2 groups to evaluate the impact of postoperative adjuvant therapy (chemotherapy vs. irradiation). RESULTS Patients of stage 0 had a significantly better prognosis than patients of stage I (p = 0.035). Stage I patients treated by irradiation showed a significantly better prognosis than patients treated by chemotherapy (p = 0.017). CONCLUSION Tumour penetration through the basement membrane causes prognosis to deteriorate significantly (5-year survival rate about 50% in stage I). Postoperative therapy is thus indicated with stage I disease. Irradiation seems to give better results than chemotherapy.

Abstract
OBJECTIVE To evaluate the impact of postoperative therapy (chemotherapy vs. irradiation) on overall survival. DESIGN A nationwide retrospective analysis. SETTING Hanusch-Krankenhaus, Department of Gynaecology, SUBJECTS 115 patients with histologically proved primary carcinoma of the Fallopian tube: 49 received six treatment cycles of a cis-platinum regimen (group I), 24 patients were treated by full irradiation using 50 Gray minimum (group II). The two groups had a similar distribution of stage I and II; in the more advanced stages chemotherapy was the predominant method of treatment. RESULTS The five-year survival rate was 53% for women receiving irradiation as against 27% for those given cis-platinum. If the analysis was restricted to those patients with comparable stage I and stage II lesions, the p-value (0.07) was of borderline significance. There was no advantage in adding abdominal to pelvic irradiation (P = 0.62). CONCLUSIONS Stage I and stage II carcinoma is probably better treated postoperatively by radiotherapy than chemotherapy. Chemotherapy may have more therapeutic potential in patients with more advanced lesions.

Abstract
As local drug treatment grew more common, the risk of persisting trophoblast remnants increased in tubal pregnancies treated in this way. We studied the secondary surgical measures in 52 patients, who had to undergo surgery for a second time after tubal pregnancy treated with prostaglandins. The indication for revision was arrived at 30 times on the basis of laboratory parameters (increasing or constant beta-HCG) (Group I). Reoperation had to be performed 22 times because of acute clinical symptoms (Group II). Laparotomy was performed 40 times, repelviscopy 12 times. In patients of Group I, the rate of rupture, that, had already occurred at the time of secondary surgery, was significantly smaller (p < 0.0001); in that case secondary surgery was significantly more often successful (p < 0.06) in preserving the tubes. In case of constant beta-HCG values 11 patients (50% of Group II) developed acute symptoms; another 7 patients (31.8%) also had to be reoperated on due to acute complaints, although the values were already clearly reduced. The study proves, that tubal pregnancies can be reoperated with preservation of the tubes even after unsuccessful prostaglandin therapy. The starting position for secondary surgery with preservation of the tubes is much better before acute clinical symptoms occur.

Abstract
The recurrence risk of HELLP-syndrome is reported to be between 2.6% and 24%. But yet, there are no accurate case reports about this topic available. In a retrospective study, 25 patients, which had suffered from a pre partum HELLP-syndrome, were interviewed about possible subsequent pregnancies. In 7 patients 8 pregnancies were found, which began between 5 and 55 months after the HELLP-syndrome. No recurrence of a HELLP-syndrome was observed in these 7 patients. Although in 71% a hypertension had been present during the HELLP-syndrome, only 1 patient had an elevated blood pressure in the subsequent pregnancy. Whilst all of the patients with HELLP-syndrome had been delivered by cesarean section, 50% of the patients were delivered vaginally in the subsequent pregnancy. There was no evidence of maternal or neonatal complications related to HELLP-syndrome. Nevertheless, even if the recurrence risk seems to be low, pregnancies after HELLP syndrome should be observed carefully.

Abstract
The primary carcinoma of the Fallopian tube is a highly aggressive tumor which can spread by the lymphatic route. The object of the present study was to evaluate the impact of radical pelvic and para-aortic lymphadenectomy on overall survival. Radical lymphadenectomy was performed on twelve patients in addition to hysterectomy and bilateral adnexectomy (group I). Twenty-eight patients subjected only to hysterectomy and adnexectomy formed the control group (group II). On average 47.6 lymph nodes were excised per patient. As long as the carcinoma was limited to adnexa and uterus (stages I and II), no lymph node metastases were found, only in stages III and IV were lymph node metastases detectable. Even though the median survival time of group I was considerably higher than of group II (43 versus 35 months), there was no statistically significant difference between the two groups (P < 0.65). Patients with stage III and stage IV disease had relatively longer median survival times if they had a lymphadenectomy. However, the difference was not statistically significant (P < 0.91). We cannot therefore recommend routine radical lymphadenectomy for primary Fallopian tube carcinoma. Whether or not lymph node dissection would lead to better results from rational selection of patient for adjuvant therapy is not known.

Abstract
The key role of HLA polymorphism in the pathogenesis of many diseases and in determining compatibility in transplantation makes it desirable to employ automated systems for identifying HLA polymorphism. For more than one year we have used the photometer system Patimed commercially available from the Leica company. We compared the results of the conventional cell-mediated lympholysis test and conventional serological HLA typing with the results obtained by the Patimed system. Despite some good preliminary results it would be premature, in our opinion, to recommend the Patimed system for routine assessment of killer cell activity whereas we can definitely recommend the Patimed system to define HLA class I and class II molecules serologically for research or routine purposes.
