RESUMO

OBJECTIVES: Numerous studies emphasized the high prevalence of sleep problems in adolescents. However, it remains to be seen whether these problems are developmental or if they are related to pathological conditions. In order to try to answer this question, we conducted an epidemiological study investigating the prevalence and correlates of sleep disorders in a population of high school adolescents. METHOD: The sample for this investigation consisted of 652 high school students (344 males and 308 females), aged 13 to 19 years (mean age: 15.1 1.2 years), attending colleges in the North of France. Data for the study were obtained by means of revised versions of the INSERM self-report questionnaires for adolescents. One questionnaire included 113 response choice items investigating the sleep parameters and the sociodemographic, behavioural, health, and environmental condition of the subject. This questionnaire was completed by a self-portrait questionnaire including 27 response choice items about mood, anxiety, instability and the quality of relations with others. In addition, a clinical examination was performed by the clinicians of the school health department in order to investigate the medical history of the subject and his (her) pubertal development. RESULTS: In a first step, statistical analysis showed some significant differences in sleep rates and troubles between males and females. If the total sleep time was found similar in males and females, females were found exhibiting significantly earlier bedtime (p<0.01) and waking time (p<0.005) than males. In addition, trouble falling asleep (p<0.0001), nightmares (p<0.001), need for daytime sleep (p<0.05), and stimulant pill intake (p<0.05) were found significantly more frequent in females. Then, the adolescents were classified into two subgroups. "Insomnia group" included the students who answered "often" or "always" to one of the five questions about: having trouble falling asleep, the occurrence of early awakenings, their need for daytime sleep, sleeping pill intake, and bad sleep quality. "Non insomnia group" included those who answered "never" or "sometimes" in response to the five questions. Results showed that 233 adolescents (35.7%) exhibited persistent sleep disorders, insomnia type. 40.2% of females and 31.6% of males were included in the "insomnia group" (p<0.05). Pubertal development was found significantly more advanced in the "insomnia group" adolescents, more particularly in females. In the same way, concerns about body weight (46.7% vs 38.8%; p<0.005), size and shape (15% vs 8%; p<0.01) were found significantly more frequent in the "insomnia group"; 32.3% of the "insomnia group" adolescents vs 17.9% in the "non insomnia group" reported health problems (p<0.0001). School difficulties were found significantly more frequent in the "insomnia group" compared to the "non insomnia group". The proportion of subjects who have previously repeated at least one school year (p<0.01), who reported bad school performances (p<0.01), and who reported to be "sometimes" or "often" away from school (p<0.01) was significantly higher in the "insomnia group" than in the "non insomnia group". In the same way, data showed that school investing was also significantly weaker in the "insomnia group" adolescents (p<0.01). The proportion of subjects who believed that their relations with parents (12.4% vs 6%; p<0.05), teachers (21.4% vs 10.5%; p<0.0001), or peers (10.2% vs 4.1%; p<0.002) was found significantly higher in the "insomnia group". Risk behaviours were also significantly more frequent in the "insomnia group" adolescents: suicidal ideation (25.1% vs 11.7%; p<0.001), suicide attempt (7.3% vs 3.6%; p<0.05), psychotropic drug use (11% vs 4.9%; p<0.02), regular stimulant drug use (10% vs 5.1%; p<0.005), regular tobacco use (7.8% vs 2.2%; p<0.001), regular alcohol use (13.3% vs 8.3%; p<0.05), and illicit drug use (5.2% vs 1%; p<0.001). Lastly, all the dimensions of the self-portrait were found significantly more affected or negative in the "insomnia group" than in the "non insomnia group". For example, the proportion of subjects who described themself usually sad (10.2% vs 3.4%; p<0.001), anxious (54.9% vs 40.5%; p<0.0001), downcast (41.1% vs 32.6%; p<0.05), or instable (56.9% vs 41.7%; p<0.0001) was significantly higher in the "insomnia group". CONCLUSION: In this descriptive study, if some data suggest that pubertal development may be involved in the sleep rates or troubles observed in adolescents, the results also show that persistent sleep disorders are significantly associated with physical, psychological or social difficulties. In summary, this study shows that it is essential to take an interest in the quality of sleep in adolescents, which may be a way to approach their psychosocial difficulties.

RESUMO

OBJECTIVE: The aim of the study is to analyze the histological-cytological correlations for Pap smears having detected cancer or high-grade squamous intra-epithelial lesion (HSIL) of the cervix. PATIENTS AND METHOD: The study about 311 women is retrospective. The average age is 36.4 years. Group 1 (histological diagnosis of high-grade or invasive lesion) includes 244 women (77.5%). Group 2 (histological diagnosis other than high-grade or invasive lesion) includes 37 women (11.9%) with a presumed diagnosis of HSIL. Group 3 (absence of histological follow-up) includes 30 women (9.6%) with a presumed diagnosis of HSIL. RESULTS: In group 1, the presumed cytological diagnosis is HSIL in 229 cases, squamous carcinoma in 11 cases and adenocarcinoma in two cases. In this group, the average delay between the Pap smear and the first histology is equal to two months. It is longer than 6 months in seven cases. The diagnosis of cancer or high-grade lesion is confirmed histologically on a first biopsy of the cervix in 196 cases, a second or a third biopsy in 10 cases, an endocervical curettage in six cases and a surgical specimen in 32 cases. In the group 2, the histological diagnosis is normal-benign in 14 cases (presumed cytological false positives) and condyloma-CIN 1 in 23 cases (presumed overevaluations). DISCUSSION AND CONCLUSION: Results highlight benefits of interactive exchanges between clinicians and pathologists, and the necessity of review of discordant cases by several pathologists in due time, with written comments and coding of the conclusions of the review. Histological follow-up is late or not done in some women.

RESUMO

OBJECTIVE: To study the influence of energy and macronutrient intake on infant birthweight in women with gestational diabetes mellitus undergoing intensive management. DESIGN: This prospective study evaluated the impact of intensive management of gestational diabetes on maternal and fetal morbidity, and addressed the relationship between food intake and infant birthweight. SETTING: Fifteen maternity hospitals in northern France. SUBJECTS: Ninety-nine women with gestational diabetes or gestational mild hyperglycemia diagnosed between 24 and 34 weeks of gestation were surveyed. After 1 was excluded because of a premature birth and 18 were excluded as underreporters, 80 women were included in the final analysis. Diet intake was assessed by a dietary history at the first interview, and by two 3-day diet records at the 3rd and 7th week after diagnosis. RESULTS: In a forward-stepwise regression analysis (controlling for maternal age; smoking; parity; prepregnancy BMI; pregnancy weight gain; gestational duration; infant sex; fasting and 2-hour postprandial serum glucose; insulin therapy; and energy, fat, protein and carbohydrate intake during treatment) infant birthweight was positively associated with gestational duration (beta = +0.34, P<.002), and negatively with smoking (beta = -0.27, P<.02) and carbohydrate intake (beta = -0.24, P<.03). There were no large-for-gestational-age infants among women whose carbohydrate intake exceeded 210 g/day. CONCLUSION: For women with gestational diabetes undergoing intensive management, higher carbohydrate intake is associated with decreased incidence of macrosomia. APPLICATION: These findings suggest that nutrition counseling in gestational diabetes must be directed to maintain a sufficient carbohydrate intake (at least 250 g per day), which implies a low-fat diet to limit energy intake. A careful distribution of carbohydrate throughout the day and the use of low-glycemic index foods may help limit postprandial hyperglycemia.

RESUMO

In order to compare the diagnostic significance of hormonal and ultrasonic criteria of polycystic ovarian syndrome (PCOS), the presence or the absence of ultrasonographic and hormonal features of PCOS were recorded in a heterogeneous population of 90 women presenting with hyperandrogenism and/or menstrual disorders. On clinical and hormonal grounds exclusively, these patients could be separated into five diagnostic subgroups: presumed cases of PCOS (n = 21), idiopathic hirsutism (IH) (n = 26), hypothalamic anovulation (HA) (n = 11), hyperprolactinemia (HPRL) (n = 9), and miscellaneous or undetermined diagnosis (n = 23). By the means of a computed automatic classification of patients (cluster analysis) using five hormonal and ultrasonic criteria of PCOS, four homogeneous clusters of patients were obtained. Cluster #1 (25 patients) had the most characteristic profile of PCOS. It included 15 cases of PCOS and 7 cases of IH. Cluster #4 (47 patients) had the less characteristic profile of PCOS. It included the majority of patients with HA and HPRL and the half of the patients with IH. Cluster #2 included only two hyperandrogenic patients, who were massively obese and in whom ultrasonography may have failed to detect PCOS. Cluster #3 (16 patients) included patients from each diagnostic group, who were gathered together because ultrasonographic and hormonal features were, respectively, present and absent in nearly all of them. With the same analysis, the criteria of PCOS could be graded according to their grouping potential. The presence of an abnormal ovarian stroma by ultrasonography appeared as the most potent criterion. Elevated serum testosterone and androstenedione levels and the polyfollicular pattern of ovaries gave intermediate results, while elevated basal LH level was a much weaker grouping parameter. In conclusion, the automatic classification of patients by cluster analysis using both hormonal and ultrasonographic criteria revealed that the classical diagnostic classification, relying upon hormonal data exclusively, may arbitrarily separate patients having the same disease; and that ultrasonography affords pertinent information that should help provide a better diagnostic definition of PCOS.

RESUMO

PRL has a definite activity in the induction and promotion of mouse and in the growth of rat mammary tumors. We and others have found that human PRL or growth hormone (GH) had a growth promoting effect on human mammary cancer cells. It has been shown that prolactin receptors (PRL-R) which are specific for all lactogenic hormones (hPRL, hGH, hPL) are present on mammary cancer cells in long-term tissue culture and also in tumor biopsies. We found that 43% of the tumors had free PRL-R (FPRL-R) and that 72% had total PRL-R (TPRL-R) which have been desaturated in vitro. A significant correlation (Spearman test) was found between PRL-R (especially TPRL-R) on the one hand, estradiol (P less than 0.001) and progesterone receptors (P less than 0.01) on the other. The demonstration of PRL-induced proteins (PIP) might be a better sign of PRL sensitivity than the existence or PRL-R; PIP have been found by Northern blot analysis in 47% of 70 breast cancers. Overall survival (OS) and relapse-free survival (RFS) analysis with a median duration of follow-up of 5.3 yr showed that TPRL-R had a significant prognostic value only in node positive patients (chi 2 = 5.61, P = 0.02). Neither FPRL-R or TPRL-R were a significant prognostic factor when studied by Cox analysis. This confirms our previous results. Since at least some human mammary cancers appear to be PRL-dependent we carried out a multicenter randomized trial comparing as the first hormonal treatment tamoxifen (TAM) (30 mg/day) + bromocriptine (B) (5 mg/day) vs TAM + placebo. 171 patients entered this trial. No difference was observed between the two groups in response rates, duration of response or survival. Recent studies are thus in favor of a role of lactogenic hormones during the course of breast cancer. However no improvement in therapy has been observed yet. The combination of drugs to achieve a total anti-lactogenic treatment, the use of anti-PRL-R antibodies are interesting areas of research; the recent cloning of PRL-R and GH receptors may open new clinical perspectives.

RESUMO

To appreciate the IGF1 sensitivity of breast tumors we detected IGF1-R with a biochemical assay (RRA). We then localized and quantified IGF1-R on frozen tissue sections by histo-autoradiographic analysis (HAA). In some cases, the IGF1 and IGF1-R mRNA expression were studied by Northern blot analysis. We also studied the IGF1 plasma concentration in primary breast cancers compared to controls. IGF1-R (RRA) were found in 87% (n = 297) of the breast cancers. The mean geometric value was 3.87% (specific binding as percentage of total radioactivity); we found a highly significant correlation between IGF1-R and ER on the one hand (P = 0.0001) and PgR on the other (P = 0.0001) (Spearman test). The presence of IGF1-R was associated with a better prognosis, either on relapse-free survival (actuarial analysis: P = 0.004; Cox analysis: P = 0.005) or overall survival (respectively P = 0.003; P = 0.005). The median duration of follow-up was 30 months. By Cox analysis IGF1-R was a better prognostic factor than ER and PgR. In a series of 77 cases of benign breast disease only 47% (36/77) were positive; the mean geometric level was 1.8%. The HAA IGF1-R quantification in 20 breast carcinomas and 12 cases of benign breast disease confirmed the RRA results and demonstrated that the labeling was localized on the epithelial component. In four breast cancers, we did not detect IGF1 mRNA; IGF1-R probe demonstrated two major mRNAs of 11 and 7 kB. Finally we found that IGF1 plasma level was higher in breast cancer patients than in healthy controls of the same age. These results show that IGF1 is implicated in breast cancer growth and suggest that anti-IGF1 treatment might be useful in human breast cancer: for this reason, we and others carried out a phase II clinical trial with somatostatin.

RESUMO

Overall survival (OS) and relapse free survival (RFS) were studied in 297 patients according to the presence of insulin-like growth factor 1 receptors (IGF1-R). All the patients were surgically treated for locoregional disease in the same institution from January 1986. The median duration of follow-up was 40 months. RFS was better in patients with IGF1-R in their tumors as assessed by actuarial survival (P = 0.014) as well as Cox analysis (P = 0.016). OS was better in IGF1-R positive tumors studied by actuarial (P = 0.007) as well as Cox analysis (P = 0.010). By Cox analysis the other prognostic factors on RFS were estrogen receptor (P = 0.002), progesterone receptor (P = 0.002), axillary node metastases (P = 0.032), histoprognostic grading (GHP) according to the standard of Scarff and Bloom (P = 0.004), and tumor diameter (P = 0.019). The other prognostic factors on OS (Cox analysis) were estrogen receptor (P = 0.001), axillary node metastases (P = 0.010), GHP (P = 0.009), progesterone receptor (P = 0.012), and tumor diameter (P = 0.007). When combining IGF1-R, GHP, and axillary node metastases, it appeared that IGF1-R, GHP, and axillary node metastases had independent prognostic significance. In this prospective study IGF1-R had a prognostic significance on RFS as well as on OS studied by actuarial as well as Cox analysis.

RESUMO

Thin-section computed tomography (CT) was performed in 244 patients with infiltrative lung diseases and 29 healthy control subjects to evaluate the frequency, profusion, and diagnostic value of subpleural parenchymal micronodules. These areas of increased attenuation (less than 7 mm in diameter) were analyzed in four groups: coal miners with chest radiographic findings of coal worker's pneumoconiosis (n = 61), coal miners with no radiographic evidence of pneumoconiosis (n = 73), patients with nonoccupational chronic infiltrative lung disease (n = 110), and healthy adults (n = 29). Subpleural parenchymal micronodules were observed with high frequency in pulmonary lymphangitic carcinomatosis, coal worker's pneumoconiosis, and sarcoidosis but were also seen in 14% of control subjects. Predominant sites of lesions were the posterior subpleural areas in the upper lobes. Subpleural parenchymal micronodules have no diagnostic value when observed as an isolated CT finding but may suggest that diagnosis of pneumoconiosis, sarcoidosis, or pulmonary lymphangitic carcinomatosis when observed in association with mild parenchymal lesions.

RESUMO

Cytogenetic analysis was successfully performed at diagnosis in 283 patients with de novo acute myeloid leukaemia (AML), including eight children aged 6-15 and 275 adults. Mean age was 50.3 (range 6-86) and the M/F ratio was 1.23. 214 patients were treated by intensive chemotherapy and 75.2% achieved complete remission. Patients with inv(16) and t(8;21) had very high CR rates whereas those with complex cytogenetic abnormalities (with or without involvement of chromosomes 5 and/or 7) had a poor response to therapy. Other karyotypic abnormalities and normal karyotypes were associated with intermediate CR rates. In a multivariate analysis, cytogenetics were the best prognostic factor of the achievement of CR, followed by age and platelet count. Median actuarial disease-free survival (DFS) of the patients who achieved CR was 19 months. No significant differences in actuarial DFS were found according to karyotype. However, no relapses were seen in patients with inv(16) and t(9;11) or its variants. Conversely, the median DFS was only 12.5 months in patients with t(15;17). Median actuarial DFS was 24 months in patients with t(8;21), but a high incidence of early relapses were seen, and the actuarial DFS was only 54% at 12 months. Patients with trisomy 8 also had a median actuarial DFS of 24 months. Our findings do not support the previously reported 'favourable' prognosis of t(15;17) translocations. They suggest that, although it is characterized by a high CR rate, t(8;21) might be associated with a high incidence of early relapses and that, finally, inv(16) might be the only 'favourable' cytogenetic rearrangement in AML. Furthermore, the prognosis associated with t(9;11) or its variants (at least in adults), and trisomy 8 might be less severe than suggested in other studies.

RESUMO

We report a series of 39 cases of acquired idiopathic sideroblastic anemia accounting for 12 p. 100 of the 330 cases of myelodysplastic syndrome diagnosed in our department in six years. Patients' mean age was high (70.8 years). Anemia was present in 92 p. 100 of the cases and was of the macrocytic type in 87 p. 100 of the patients. Only two patients (5 p. 100) had neutropenia and two (5 p. 100) had thrombocytopenia. Thrombocytosis was observed in 17 cases (43 p. 100); it was usually moderate. The mean proportion of medullary ring-sideroblasts was 35 +/- 14 p. 100. A clonal abnormality was found in 4 of the 11 karyotype examinations performed. The course of the disease was marked by recurrences of anemia which required regular blood transfusions in 82 p. 100 of the cases. In at least 30 p. 100 of the patients followed up for more than 30 months, these transfusions were responsible for secondary haemochromatosis. Conversely, in only three patients (7.5 p. 100) the disease progressed to acute leukemia. On the other hand, 4 patients (10 p. 100) developed thrombocythemia (greater than 1,000 x 10(9)/1). Median actuarial survival rate was 48 months. There were only two factors of poor prognosis: age over 70 and anemia with less than 8 g/dl haemoglobin at the time of diagnosis. Transfusion haemochromatosis is the principal risk in acquired idiopathic sideroblastic anemia: this risk can be prevented by iron chelating agents in patients with frequent blood perfusions.

RESUMO

From 1973 to 1986 we splenectomized 181 patients with chronic ITP after platelet kinetic studies with 51Cr or 111In. Mean age at diagnosis was 34 (range 4-79 yr). Follow-up of at least 1 yr after splenectomy was available in every patient. 141 patients (78%) achieved remission (platelets greater than 100 x 10(9)/l by 3 months after splenectomy), of whom 9 subsequently relapsed. Among the 40 non-responders at 3 months, 3 achieved a later remission spontaneously. Factors associated with response to splenectomy included a high post-operative platelet count (p = 0.0001), younger age at the time of surgery (p = 0.0077) and predominantly splenic sequestration of platelets (p = 0.0002), the two latter factors being partially correlated. In a multivariate analysis, however, only post-operative platelet count and age retained an independent prognostic significance, whereas the sequestration site of platelets had only borderline value. These results are discussed in the context of indications of platelet kinetic studies in chronic ITP, before splenectomy is considered.

RESUMO

Insulin-like growth factor 1 (IGF1) binding sites were characterized in breast cancer. We demonstrate the presence of one high affinity binding site. Chemical cross-linking of 125I-IGF1 to breast cancer membranes in reducing condition and sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed one band with an apparent molecular weight of 130,000. The specificity of the binding was studied. IGF2 was a good competitor whereas insulin competed with a potency lower than 1/100 that of IGF1. This IGF1 binding corresponded to the previously described type 1 IGF receptor (IGF1-R). IGF1-R was determined in 76 human breast cancer biopsies. Ninety-three % of the tumors were positive. The specific binding range was 0-16.4%; the geometric IGF1-R mean level was 3.9%. There was a relation (chi 2 test) between IGF1-R and progesterone receptor positivity rates (P = 0.002). The IGF1-R concentrations were correlated (Spearman test) with those of estradiol receptor (P = 0.0018) and progesterone receptor (P = 0.0011). A positive linear correlation existed between IGF1-R and estradiol receptor (P = 0.006) and between IGF1-R and progesterone receptor (P = 0.003). Our demonstration of the presence of IGF1-R in human breast cancer biopsies suggests that IGF1, acting either via the endocrine, paracrine, or autocrine pathways, could stimulate tumor growth.

RESUMO

Cytogenetic analysis was performed in 47 newly diagnosed patients with agnogenic myeloid metaplasia (AMM); 32 had a normal karyotype (68%, group I), whereas 15 had clonal abnormalities (32%, group II). The most frequent abnormal findings were a 20q- deletion in six cases (either alone or within complex anomalies), interstitial 13q- deletion in three cases (and monosomy 13 in one case), and acquired trisomy 21 or 21p+ in three cases. Four cases exhibited complex aberrations involving several chromosomes, sometimes with a mosaicism. In two patients with an initial abnormal karyotype, further cytogenetic analysis during the disease course showed the appearance of additional clonal anomalies, and particularly of a probable Philadelphia (Ph1) variant in one case. Treatment was essentially supportive. Survival was significantly shorter in group II (median, 30 months) compared with group I (median, not reached at 6 years; P = .015). In univariate analysis, other parameters significantly associated with a poor prognosis (P less than .05) were higher age, anemia, and increased percentage of circulating blasts. However, in a multivariate analysis, only cytogenetic abnormalities and age retained their independent prognostic value.

RESUMO

Adult chronic myelomonocytic leukemia (CMML), as defined by the French-American-British (FAB) group, is associated with a variable survival, ranging from a few weeks to several years. From 1971 to 1986, we made the diagnosis of CMML in 107 cases, according to FAB criteria (except for patients with 20% to 30% bone marrow [BM] blasts who were also included). Median survival was 30 months (range 1 to 81 months) and life expectancy did not seem to be influenced by treatment modalities other than supportive care. Eighteen patients (17%) progressed to acute nonlymphoblastic leukemia (ANLL). In a Cox regression model, main factors associated with short survival were: an excess of marrow blasts (P = 10(-6], anemia (P = .17 x 10(-5], high peripheral blood (PB) monocytosis (P = .26 x 10(-5], presence of PB blasts (P = .49 x 10(-4], and to a lesser extent hyperleukocytosis (P = .001), presence of PB immature granulocytes, thrombopenia, and splenomegaly. Survival (less than 1 year v greater than 1 year) could be predicted at diagnosis in a multivariate stepwise discriminant analysis using two parameters only (percentage of BM blasts and hemoglobin level), with 82% accuracy. Among patients surviving greater than 1 year, initial PB leukocyte count was higher in patients with intermediate survival (12 to 42 months) than in long survivors (greater than 42 months) and was the only discriminating factor between these two subgroups in multivariate analysis. Abnormal cytogenetic findings and increased lysozymuria were also poor prognostic factors, but could not be analyzed in the multivariate models, as they were determined in a minority of patients. Parameters associated with subsequent progression to ANLL included younger age at diagnosis, thrombopenia, increased BM blasts, and splenomegaly. Our study allows for the identification of subgroups with different prognoses in CMML, on the basis of a small number of hematologic parameters, particularly initial percentage of BM blasts, hemoglobin level, and leukocytosis. These subgroups probably require different therapeutic approaches.

RESUMO

Between 1980 and 1986, we diagnosed refractory anaemia (RA), according to the FAB classification, in 69 patients, who constituted 22% of the 312 cases of myelodysplastic syndromes (MDS) seen over that period. The haematological features were variable, with pancytopenia in 14 cases (20%), bicytopenia in 24 (36%) and mono-cytopenia in the remaining patients, including 21 (30%) cases of anemia alone, 8 (12%) cases of refractory neutropenia and 2 (3%) cases of refractory thrombocytopenia. Myelodysplastic features were also quite variable, involving one, two or all three lineages. In patients with a single cytopenia or only one dysplastic lineage, FAB criteria appeared insufficient for adequate inclusion among RA and we suggest more precise diagnostic criteria, resulting from the utilization of cytogenetics, ferrokinetics, progenitor cultures and perhaps molecular biology, in such cases. Median survival was 42 months. 12 patients (17%) progressed to RAEB (of whom 7 finally developed ANLL) and 4 patients (6%) to CMML. In spite of the heterogeneity of haematological features, only two factors were associated with poor prognosis, namely age greater than 70 yr at diagnosis and haemoglobin less than 10 g/dl, whereas, to a lesser extent, neutropenia was associated with progression to RAEB.

RESUMO

Fifty-four patients who had consulted because of their sterility had a laparoscopy carried out with bacteriological, cytological and biochemical studies of the peritoneal fluid as well as a histological assessment of the peritoneal adhesions. The purpose of this prospective study was to show the usefulness of laparoscopy in pre-operative assessment of tubal sterility and to look for objective criteria of the progress of inflammation. To do the study, two groups of women in different clinical stages (29 patients with no pelvic infection and 25 patients who had salpingitis) were divided into three sub-groups: 25 free of disease, 4 subsiding salpingitis patients and 25 with tubo-peritoneal sequellae. Different samples taken with the laparoscope made it possible to decide whether the inflammatory process was carrying on or not in these 25 cases. Using swabs for bacteriological examinations we had to employ transport medium and this showed bacteria in 7 cases. We found a significant correlation between the serum and peritoneal levels of anti chlamydia antibodies and the levels of AC antibodies when there was a tubal lesion. There was little value in carrying out cytology on the peritoneal fluid except when the histology showed that this was necessary. The level of serum and peritoneal orosomucoid was found to be different in the two groups of patients. This study shows that it is necessary to assess several different parameters to exclude pelvic inflammatory disease before resorting to reparative tubal surgery.

RESUMO

Overall survival and relapse free survival (RFS) were studied in 547 patients according to the presence of prolactin receptors (PRL-R), either free or total (after 3 M MgCl2 desaturation). All these patients were surgically treated for locoregional disease in the same institution between 1978 and 1984. In actuarial survival studies, RFS was higher in total PRL-R positive patients in the whole population (P less than 0.02). When the population was divided into two groups, according to either the presence or the absence of node metastasis or the presence or absence of estradiol receptor, the higher RFS was restricted to node positive (P less than 0.001) and to estradiol receptor positive patients (P less than 0.01). The Cox analysis on RFS showed that free PRL-R alone was a significant prognostic factor in estradiol receptor positive patients; total PRL-R alone was never significant; when considered together with steroid receptors, free as well as total PRL-Rs were significant prognostic factors in some subgroups of patients.

RESUMO

Free (n = 432) and total (n = 387) prolactin receptors (PRL R) (after 3 M MgC12 desaturation) as well as estradiol (ER) and progesterone receptors (PgR) were measured in 547 breast cancer patients surgically treated in the Oscar Lambret Centre. Free PRL-R were found in 43% of the cases, total PRL R in 72%, ER in 81% and PgR in 55%. A statistically significant correlation was found by the Spearman test between ER on the one hand free PRL R (P less than 0.02) and total PRL R (P less than 0.001) on the other and between PgR on the one hand, free PRL-R (P less than 0.05) and total PRL R (P less than 0.01) on the other. A linear correlation test could be done on subgroups of values, excluding zero values, of each of the receptor type; a statistically significant correlation could be found between ER and total PRL R (P less than 0.001) and between PgR and total PRL R (P less than 0.05). These results confirm, on a large series, the relation between PRL R, ER and PgR in breast cancer.
