Repeat conisation or HPV test? What should be done if histology of the primary conisation requires a second conisation?

OBJECTIVE: In our retrospective study we focused on the sensitivity of HPV DNA testing towards reducing the number of repeat (re)conisations. Is the second HPV test (pre repeat conisation) an appropriate method to reduce the number of interventions in histologically positive cases? STUDY: 438 cervical conisations--loop electrosurgical excision procedure (LEEP)--were performed between March 2008 and August 2010 at our Gynaecology Department. Samples for high-risk HPV testing (Genoid, Hungary) were taken from the surface of the cervix and from the cervical canal before the LEEP procedure, and histopathological examinations were performed. Margin positivity was the indication for re-conisation (re-LEEP). RESULTS: 119 (27.2%) out of 438 cases were re-conisations. In cases of histologically proven residual dysplasia (29 of 119) high-risk HPV infection was also detected by HPV testing. In 90 cases of 119 residual dysplasia was not seen by histological examination. In this high-risk group HPV infection had not been detected in 77 cases (85.5%) by the time the second HPV test was performed. HPV tests for high-risk types were positive only in 13 of 90 (14.5%) without residual dysplasia. Furthermore the same HPV type was detected only in three cases taken before the first and second conisation procedure. CONCLUSION: Pre re-conisation HPV testing might be useful in reducing the number of re-conisations where the high-risk HPV test is either negative or does not confirm the previously proven HPV type.

ErbB-2/HER-2 protein expression, serum tumour necrosis factor-alpha (TFM-alpha) and soluble tumour necrosis factor receptor-2 (TNFR-2) concentrations in human carcinoma of the uterine cervix.

The expression of erbB-2 protein (by immunohistochemistry), serum TNF-alpha, soluble TNF-receptor 2 (sTNFR-2, ELISA) concentrations and mitogenic (LPS, ConA, PHA) induced TNF-alpha production of the peripheral blood mononuclear cells (PBMNC) were studied in 91 (UICC Stage 1: 39, Stage 2: 33, Stage 3: 14, Stage 4: 5) patients with carcinoma of the uterine cervix. During a follow-up period of seven years 30 patients died (Stage 4: 5, Stage 3: 12, Stage 2: 11, Stage 1: 2). ErbB-2 protein expression was significantly more frequent in patients with UICC Stages 3-4 (14/19), and in those with fatal outcomes (14/30, p < 0.0001, chi-square test). Serum TNF-alpha (2.70 +/- 0.69 pg/ml) and sTNFR-2 (3.85 +/- 1.05 ng/ml) concentrations were significantly lower in cancer patients (p < 0.0001, Mann-Whitney test) as compared to 64 age-matched control women (TNF-alpha: 4.32 +/- 0.36, TNFR-2: 4.85 +/- 0.82). The mitogenic induced TNF-alpha production of PBMNC was also significantly less with all the three mitogens applied (LPS: 35.24 +/- 8.84, ConA: 26.28 +/- 7.81, PHA: 20.48 +/- 7.04 pg/l million of cells/24 hours, p < 0.0001) as compared to the controls (LPS: 65.33 +/- 8.82, ConA: 51.00 +/- 8.87, PHA: 41.80 +/- 9.01). Serum TNF-alpha, sTNFR-2 concentrations and the mitogenic induced TNF-alpha production of PBMNC was significantly decreased in patients with erbB-2 positivity as compared to those with negativity. In conclusion the expression of the oncoprotein and the lower levels of the members of the TNF system seem to be poor prognostic parameters in patients with carcinoma of the uterine cervix.

Role of tumour necrosis factor-alpha in insulin resistance during normal pregnancy.

OBJECTIVE: Role of tumour necrosis factor-alpha (TNF-alpha) was studied in insulin resistance during pregnancy. STUDY DESIGN: Serum TNF-alpha (ELISA) and fasting C-peptide (Cp) (RIA) concentrations were measured in 40 healthy pregnant women (15, 12 and 13 of them in the 1st, 2nd and 3rd trimesters, respectively) and in 25 healthy non-pregnant women in a case-control study. RESULTS: TNF-alpha (X+/-S.D.: 5.33+/-0.46 pg/ml) and Cp levels (3.37+/-1.30 ng/ml) were significantly higher in the 3rd trimester as compared with matched healthy controls (TNF: 4.07+/-0.26, Cp: 1.05+/-0.36) and to the pregnant women in 1st (TNF: 4.04+/-0.26, Cp: 1.34+/-0.59) and 2nd (TNF: 4.35+/-0.32, Cp: 1.11+/-0.35) trimesters. Significant positive linear correlation was calculated among TNF-alpha, Cp, Cp/blood glucose ratio (indirect parameters of insulin resistance) and body mass indexes (BMIs) of pregnant women (P<0.01). CONCLUSION: TNF-alpha may contribute to the insulin resistance during the course of normal pregnancy.

[Successful outcome of an intrauterine twin pregnancy combined with ectopic pregnancy]. / Méhen kívüli terhességgel szövödött, sikeresen kiviselt méhen belüli ikerterhesség esete.

Authors present a case of twin intrauterine pregnancy combined with ectopic pregnancy. The simultaneous pregnancies occurred after the use of clomiphene citrate. In this case viable intrauterine twin gestation was observed by vaginal ultrasound examination, the simultaneous ectopic pregnancy was observed by laparotomy. Right salpingectomy was performed. The intrauterine twin pregnancy continued normally to the 35th week of pregnancy, finished with normal vaginal delivery. The healthy twin boys weighed 2650 g and 2070 g left the hospital in a good general condition on the 5th past delivery day. Authors discuss the etiology, the mode of diagnosis and the therapy of this rare condition.

Massive aneurysm of the right coronary artery causing sudden death.

Coronary artery aneurysms due to atherosclerosis are increasingly recognised during angiography yet the natural history of these abnormalities has not yet been defined. Only rarely has massive dilatation been observed, usually presenting following death. We report a case of sudden death due to rupture of a massive right coronary artery aneurysm measuring 10 x 5 cm. Diagnosis was made at post-mortem.

Treatment of ventilatory failure in the Prader-Willi syndrome.

Hypercapnic respiratory failure is a common cause of death in the Prader-Willi syndrome. Its relationship to sleep-disordered breathing has not been established and there are no reports of its successful treatment. We have retrospectively reviewed the records of four patients with the syndrome, who developed ventilatory failure. Daytime arterial blood gas tensions and overnight oximetry traces before and during treatment were compared. Each patient had severe sleep-disordered breathing in association with daytime ventilatory failure. The median overnight mean arterial oxygen saturation (Sa,O2) was 82% and the median minimum was only 41.5%. Initial treatment was with nasal intermittent positive pressure ventilation, and in each case the daytime arterial blood gas tensions were normalized. The patients were maintained on nasal continuous positive airway pressure at night after discharge. Compliance has been good, and at last follow-up (after a median of 4.8 yrs) the daytime arterial gas tensions remained normal, while the median overnight mean arterial oxygen saturation was 95.5% and the median minimum was 84.5%. This study of patients with the Prader-Willi syndrome shows that daytime ventilatory failure is associated with sleep-disordered breathing. It can be reversed with nocturnal noninvasive ventilation and maintenance treatment with continuous positive airway pressure is well tolerated, with no deterioration in respiratory parameters.

The unemployment insurance compensation. Usage of Canada's immigrants in selected provinces, 1981-1988.

PIP: "This paper explores the relationship between province of residence and the use of unemployment insurance (UI) among immigrants who landed in Canada during the period 1981-88. Use of a new data set, the Longitudinal Immigration Data Base, overcomes the restriction that other data sets are cross-sectional only in nature or do not identify birthplace. Our principal conclusion is that more generous UI benefits and poorer economic conditions than the Canadian average have a positive impact on the fraction of immigrants who receive UI. In addition, the province of residence has a separate effect on the likelihood of claiming UI, perhaps due to mobility costs. Because national immigration policies have a differential impact across provinces, it is understandable that provincial policymakers wish to have greater influence over federal immigration policies."

The unemployment insurance compensation experience of immigrants in Canada, 1980-1988.

PIP: Some have questioned whether immigrants to Canada use government entitlement programs to an extent which is disproportionate to their numbers. A new data set compiled by Citizenship and Immigration Canada, Revenue Canada, and Statistics Canada is used to examine the unemployment experience of Canadian immigrant cohorts during 1980-88. On the basis of the review of records of unemployment insurance (UI) benefits of individuals who immigrated to Canada during those years and who filed income tax returns, unemployment experiences are compared by landing year, gender, level of education, language ability, and country of last permanent residence. The determinants of the proportion of each immigrant cohort which received UI benefits are then estimated by relating the proportions to landing year, duration of time in Canada, and labor market conditions. No obvious influence upon UI receipt behavior following the immigration reforms of 1982 was identified. The recession of 1981-82 did, however, have a major impact upon incomes which failed to recover until 5-6 years later. More generous UI benefits slightly increased the likelihood of UI receipts.^ieng

A simplified version of the "Indiana pouch" technique for urinary diversion. Experience of the first 18 cases.

During the last 3 years, a modified technique of the continent urinary diversion, known as the "Indiana pouch" has been performed in 18 patients as part of pelvic exenteration. The narrowing of the ileum and/or the site of Bauchin valve was excluded from the procedure. In order to achieve anti reflux effect, ureters were implanted to the urinary reservoir by the "split cuff nipple" technique instead of tunnelling ureters. Sufficient urine continence and lack of urine reflux in the ureters indicated that satisfactory function could be achieved by the simplified technique. A quality of life questionnaire has suggested that most of our modified Indiana Pouch patients coped well. Operative technique, indications, operative results, and complications are discussed.

[K-cell activity in patients with germ cell testicular tumors. Effect of cytostatic therapy]. / Csírasejt eredetü heredaganatban szenvedök K-sejt aktivitásának vizsgálata. A citosztatikus kezelés hatása.

The antibody-dependent cell mediated cytotoxicity of peripheral blood mononuclear cells from 92 patients with germinal cell tumours and 60 healthy male controls was measured against 0, Rh(D) positive human red blood cells sensitized with anti-D antibody. To determine the maximal K-cell activity the enzym-like kinetic model of citotoxicity was employed in which maximal activity was measured in presence of target-cell excess. To avoid variation due to the individual sensitivity of target erythrocytes red blood cells were obtained from a single donor. It was demonstrated that compared to the control group the K-cell activity of patients with germinal cell tumours was significantly enhanced. Cytotoxic activity of patients with clinically detectable tumours was significantly higher than that of patients with no detectable tumour. The K-cell activity of patients with detectable tumours was significantly increased after chemotherapy.

Experience with a new combined method in the differential diagnostics of early endometrial changes.

The authors have performed in 30 cases ultrasonic examination of the endometrium followed by vacuum aspiration with TIS-U-TRAP device (Milex Prod. Inc., Chicago) with equipped a transvaginal head, to obtain samples for histological examination. In 8 of the 30 cases endometrial hyperplasia, while in 2 cases endometrial adenocarcinoma was verified. The authors suggest that transvaginal ultrasonic examination together with vacuum aspiration is suitable for oncological screening of the endometrium.

Serum dehydroepiandrosterone and cortisol concentration in the maternal-fetoplacental hormonal system in elective caesarean section and spontaneous vaginal delivery in the 28th to 36th and 40th weeks of pregnancy.

The authors compared the serum DHAS and cortisol level in 53 vaginal deliveries with those of 21 caesarean sections prior to the onset of labour at the 28th to 36th weeks. They also compared 18 vaginal deliveries with 16 elective caesarean sections at the 40th week. The serum hormone concentrations were measured in the maternal vein, the umbilical vein and the umbilical artery. The results indicate that the serum DHAS and cortisol level was higher after vaginal delivery than after caesarean section in the maternal vein, umbilical vein and umbilical artery at the 28th to 36th and also at the 40th week. The authors suggest that, although the role of the fetal adrenal cortex is not so definitive as in the case of some species in the onset of labour, it may be presumed that the increase in adrenal cortical activity cannot be explained exclusively by maternal stress.

[Prospective study of K-cell activity in patients with malignant gynecologic tumors. Effect of radiation therapy]. / Rosszindulatú nögyógyászati daganatos megbetegedésben szenvedö betegek K-sejt aktivitásának prospectiv vizsgálata. A sugárkezelés és mütét hatása.

K cell activity was measured in the enzyme-like kinetic model of cytotoxicity against O, Rh (D) positive erythrocytes in 127 patients with carcinoma of the uterine cervix, 55 with carcinoma of the corpus uteri and 30 with malignant tumors of the ovary. The control groups included 62 healthy age matched women and 39 patients with benign tumor of the ovary. The cytotoxic activity was measured in a number of cases before any treatment and after irradiation and surgery in patients with cervical and endometrial cancer. The target cells were obtained from the same donor. ADCC activity of cervical and ovarian tumor patients enhanced depends on the stage of the disease. K cell activity of endometrial carcinoma patients was similar to the controls. ADCC activity of patients with carcinoma of the uterine cervix was increased, with carcinoma of the uterine corpus was indicated an increasing tendency following irradiation. There was connection with the dose of the irradiation and K cell activity. On the contrary, operation did not influence ADCC activity.

[Uterus-bladder fistula causing repeated spontaneous abortion]. / Ismételt spontán vetélést okozó méh--hólyag sipoly.

The case of an uterus--bladder fistula which developed after a Cesarean section and caused repeated spontaneous abortion is presented. With the already existing fistula dry labor was followed by the prolapse of the umbilical cord and finally by spontaneous abortion in the course of 2 successive pregnancies. As surgical solution hysterectomy and closing of the bladder fistula were carried out.

Quantitative comparison of serum steroid and peptide hormone concentrations in male and female fetuses in the maternal-fetoplacental system during the 28th-40th weeks of pregnancy.

There are a great deal of data concerning the role of testosterone in the formation of the sex of the fetus. The synthesis of the testosterone is influenced by the hypophysis and the fetoplacental unit. In this study the authors conferred the progesterone, DHAS, cortisol, oestradiol, oestriol, prolactin and HPL levels of male and female newborns in the maternal vein and in the umbilical vein and artery in the 28th-32th weeks (31 parturients, 15 male and 16 female fetuses), in the 33rd-36th weeks (43 parturients, 20 male and 23 female fetuses) and in the 40th week (34 parturients, 11 male and 23 female fetuses) of pregnancy. The determination of serum hormone concentration was carried out with the RIA method in 2084 samples. There was no significant difference between the serum hormone concentrations of the male and female sex in the 28th-40th weeks of pregnancy. They assume that in the 28th-40th weeks there is no difference in the activity of steroid and peptide hormone secretion caused by the sex of the fetus.

Serum DHAS in the maternal-fetoplacental system during the 28th-40th weeks of pregnancy.

The authors measured the serum levels of dehydroepiandrosterone sulfate (DHAS) in the maternal vein (MV), the umbilical vein (UV) and the umbilical artery (UA) during the 28th-36th weeks of pregnancy (n = 74) and in the 40th week (n = 34), to clarify the hormonal changes that occur between the maternal and fetal compartments. The following results were found: (1) The DHAS concentration increased significantly in MV, up to twice the concentration from the 28th-32nd weeks to the 33rd-36th weeks (p less than 0.01). From the 33rd-36th weeks to the 40th week it decreased significantly to one third of this value (p less than 0.01). DHAS levels revealed a decreasing tendency in the UA and UV serum from the 28th-32nd weeks to the 33rd-36th weeks, and there was a tendency to rise from the 33rd-36th weeks to the 40th week. (2) The serum DHAS values were found to be higher than in the MV, the UA-UV difference was not significant; however, the 'UA/UV X 100' value remained higher than 100% during the 28th-40th weeks. (3) The MV DHAS value showed slight correlation with the UV and UA DHAS concentration (r = 0.2951, p less than 0.01, n = 106; r = 0.2930, p less than 0.01, n = 100). There was a close correlation between the UV and UA serum DHAS levels (r = 0.8432, p less than 0.01, n = 98). The authors consider that the adrenal activity increases independently of the maternal adrenal cortex at term.

Perinatal progesterone in maternal-fetoplacental system during mature and premature deliveries.

The role of the maternal-fetoplacental hormonal system in the maintenance of pregnancy and in the onset of labor was studied by measuring the serum progesterone level in the maternal vein, the umbilical vein and artery at term (n = 34) and in the case of premature births (n = 74). Our results show: 1) During the 28th-40th weeks the serum progesterone concentration in the umbilical vein is greater than in the maternal vein (p less than 0.01) and in the umbilical artery (p less than 0.01), and greater in the umbilical artery then in the maternal vein (p less than 0.01). 2) No correlation was found between the serum progesterone concentration in the maternal and fetal vessels, whereas a close correlation was found between the serum concentration in the umbilical vein and artery. 3) The progesterone concentration of the maternal serum increased during the 28th-40th weeks, but increased only during 28th-36th week in the umbilical vein and artery and fell significantly by the 40th week. From this it appears that the maternal and the fetal progesterone concentrations are interdependent. The progesterone concentration of the umbilical vessels falls before term but it is not an essential factor in the onset of labor.
