RESUMO

Consecutive admissions to the psychosomatic departments of 5 hospital units in southwest Germany registered between October 2012 and October 2013 were asked to participate in a study investigating the treatment selection process for psychosomatic rehabilitation. 527 patients were included in the study, 269 outpatients and 258 inpatients at the end of their inpatient treatment. 52 patients (10.1%) received the recommendation for rehabilitation. 47 (90.4%) could be followed up 3 months later. 22 patients had applied for a rehabilitation treatment, 11 (50%) had obtained an approval for their rehabilitation, 5 had still no answer and for 6 patients the request was refused. 4 of the latter had objected their refusal and were still waiting for an answer. Only one patient was already admitted to a rehabilitation center. Possible reasons for the low permeability at the interface between hospital care and rehabilitation are discussed.

RESUMO

OBJECTIVES: Paget disease of the vulva is a rare lesion that accounts for <1% of vulva neoplasms. A 12% prevalence of invasive Paget carcinoma and a 4% prevalence of associated adenocarcinomas are described. Furthermore, a high recurrence rate of 30% after surgical therapy is observed. This study aims to search for therapeutic strategies for recurrent Paget disease, which are less mutilating and less aggressive than reexcision, x-ray therapy, or chemotherapy. Trastuzumab (Herceptin) is a recombinant monoclonal antibody against HER-2/neu, approved by the U.S. FDA for the treatment of patients with HER-2/neu-positive metastatic breast carcinomas. The results of recent studies indicate that HER-2/neu oncoprotein may play a role in the pathogenesis of extramammary Paget disease. METHODS: Using HercepTest, we analyzed HER-2/neu overexpression in seven noninvasive Paget lesions, two invasive lesions, and one Paget disease of the vulva with underlying adenocarcinoma. In addition, we investigated five mammary Paget diseases. RESULTS: Overexpression of HER-2/neu oncoprotein labeling exclusively the membranes of Paget cells was demonstrated in 8 out of 10 cases. One noninvasive and one with underlying adenocarcinoma stained negatively. Overexpression of HER-2/neu was demonstrated in all five cases of mammary Paget disease. CONCLUSION: Using HercepTest as a standardized detection system, overexpression of HER-2/neu can be demonstrated in a majority of both noninvasive and invasive Paget disease of the vulva. The use of Trastuzumab should be considered for the treatment of patients with recurrent Paget disease of the vulva with overexpression of HER-2/neu.

RESUMO

Most hormonally active ovarian tumors belong to the category of tumors of the gonadal stroma. These account for less than 5% of all ovarian tumors. About two-thirds of tumors of the gonadal stroma produce steroid hormones. The pathologic secretion of estrogenic or androgenic hormones leads to specific effects on the hormone-sensitive target organs. The clinical manifestations depend on both the amount of hormones secreted and the age of the patient. Tumors of the gonadal stroma are potentially malignant, ranging between noninvasive (borderline) tumors and invasive epithelial tumors of the ovary. Besides the specifically steroid hormone-producing tumors, a wide variety of ovarian tumors other than those in the stroma of the ovary and steroid cell tumors may be hormonally active as the result of an increase in and/or stimulation of nonneoplastic ovarian stromal cells within or adjacent to the tumor.

RESUMO

The aim of the trial was to determine the diagnostic accuracy of scintimmammography with technetium-99m methoxyisobutylisonitrile (99mTc-MIBI) in the detection of primary breast cancer and to verify its clinical usefulness. A total of 246 patients with a suspicious breast mass or positive mammogram were included in this prospective European multicentre trial. At 5 min and 60 min (optional) p.i. two lateral prone images were acquired for 10 min each; 30 min p.i. one anterior image was acquired for 10 min. There were 253 lesions (195 palpable and 58 non-palpable), in respect of which histology revealed 165 cancers and 88 benign lesions. Institutional and blinded read results were correlated to core laboratory histopathology results obtained during excisional biopsy. Diagnostic accuracy for the detection of breast cancer was calculated per lesion. The overall sensitivity and specificity of blinded read scintimammography were 71% and 69%, respectively. For palpable lesions, the sensitivity of blinded read and institutional read scintimammography was 83% and 91%, respectively. Sensitivity was not dependent on the density of the breast tissue. Invasive ductal and invasive lobular cancers showed similar sensitivity. The sensitivity and specificity of mammography were 91% and 42%, respectively, and did not depend on the tumour size. In 60% of false-negative mammograms, 99mTc-MIBI was able to diagnose malignancy (true-positive). High-quality imaging with 99mTc-MIBI has a high diagnostic accuracy for the detection of primary breast cancer. Used as a complementary method, scintimammography with 99mTc-MIBI can help to diagnose breast cancer at an earlier stage in patients with dense breasts.

RESUMO

Uterine tumors resembling sex-cord ovarian structures are exceptionally rare. Clement and Scully divided them into two groups. The first group includes cases with less than 50% and the second with more than 50% sex-cord elements. Group one tumors show a higher incidence of recurrences. We report a case of a 54-year-old women with a partly retroperitoneal, cystic tumor 7.6.6 cm. Histologically, sex-cord differentiation of more than 50% was seen with positive immunostaining against vimentin, desmin and focally against myoglobin and cytokeratines. The reaction against EMA, CEA and S 100 was negative. The patient was treated by abdominal hysterectomy with bilateral salpingo-oovorectomy. She shows no evidence of disease 2.3 years after the initial surgery. Based on the light microscopic features and immunohistochemical pattern, the tumor was interpreted as arising from the endometrial stromal cells or multipotential uterine mesenchyme that showed diverse differentiation toward ovarian sex-cord stroma and uterine smooth muscle with interspersed stromal cell clusters.

RESUMO

Gliomatosis peritonei (GP) is the metastatic implantation of glial cells within the peritoneal cavity of patients with ovarian teratomas. The case of a young woman is presented, who initially developed a mature teratoma in the left ovary that was surgically removed. Nine years later a mature teratoma in the right ovary was excised, upon which GP was found in the greater omentum. To identify the cellular composition of the ovarian teratoma and of the omental implants, immunostainings were performed using antibodies against glial and neuronal antigens as well as against determinants of hematopoietic cells. In the teratoma the neuroectodermal part was strongly HNK-1-positive and contained GFAP- and vimentin-positive astrocytes and some NSE-positive neuron-like cells. In addition, neuroectodermal tissue was infiltrated by numerous CD68-positive macrophages/histiocytes and CD20-positive B lymphocytes. The omental nodules consisted of astrocytes, which expressed GFAP, vimentin and desmin. The implants also contained macrophages/histiocytes, which exhibited morphologic features reminiscent of microglial cells. In GP, macrophages might release glia-promoting trophic factors, which could allow the neural component of ovarian teratoma to implant in the peritoneal cavity and survive there for many years. Macrophage-derived factors might induce astroglial differentiation, which could explain why the peritoneal implants are mostly mature even when they originate from immature teratomas.

RESUMO

Two cases of primary non-Hodgkin's lymphoma of the uterine cervix are described. Diagnostic pitfalls and therapeutic applications of this rare disease are discussed. The main approach in local therapy is external beam radiation--with or without surgical staging. Prognosis is favourable--depending on the stage of disease.

RESUMO

Between January 1991 and 1992, 5,652 cervical smears from 4,918 women were classified according to the traditional Papanicolaou/cervical intraepithelial neoplasia (CIN) categories and to the recently developed Bethesda System. Koilocytosis without atypia was identified in 3.7% (183 cases), CIN 1 in 1.8% (87 cases) and high grade squamous intraepithelial lesions (SILs) (CIN 2 and 3) in 1.9% (93 cases) (total, 363/4,918 = 7.4%). Human papillomavirus (HPV)-directed polymerase chain reaction analysis with general primers and subsequent hybridization with HPV 16/18 probe cocktail was carried out in 35% of cases with koilocytosis and dysplasia of any degree (127/363 cases). Seventy-five percent (95 cases) were positive in contrast to a detection rate of 30.8% (53/172 cases) for nonsuspicious smears. While low grade SILs were HPV positive in 67% (koilocytosis only) and 75% (CIN 1), high grade SILs harbored HPV in 87%. The rate of HPV 16/18 infections varied from 71.9% in low grade SILs to 88.9% in high grade SILs. Our results point to the questionable value of koilocytosis as a specific marker of HPV infection and call for confirmatory tests prior to classifying cervical smears suggestive of HPV infection in the low grade SIL category.

RESUMO

Recent studies indicate that in addition to free diffusion, uptake of sex hormones into target cells is mediated by sex hormone-binding globulin (SHBG). The purpose of this study was to investigate localization and distribution of SHBG in normal and neoplastic breast tissue. We examined 31 normal, 21 non-invasive, 52 invasive breast cancer tissues and 33 cases of recurrences and metastases of breast cancer immunohistochemically for SHBG by the ABC-peroxidase method, using a polyclonal, monospecific antiserum derived from rabbit. The proportion of stained cells was evaluated semiquantitatively. In 81 malignant cases the oestrogen receptor (ER) content was evaluated by the ER-ICA method. Positive staining for SHBG was found exclusively in epithelial cell cytoplasm. Benign tissue was focally SHBG-positive and showed more stained cells in proliferating epithelium. Staining of neoplastic tissue was more heterogeneous. Half of the non-invasive carcinomas were SHBG-positive; particularly the highly differentiated. Independent of subtype and differentiation, invasive tumours were SHBG-negative in 32.5% of cases, while 19.3% were SHBG-positive in most cells. In 13 cases of invasive carcinomas, associated intraductal parts showed more staining for SHBG than the invasive tissue. Recurrences and metastases of breast cancer were SHBG-negative in 45.5% of cases, while only 3% were positive in most cells. SHBG-staining was unrelated to ER content. These results suggest that the demonstration of cytoplasmic SHBG represents a physiological feature of breast epithelium and its presence is compatible with a mechanism for cellular uptake of SHBG-bound sex hormones preceding their interaction with nuclear receptors.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Twenty-five primary cervical adenocarcinomas and five cervical infiltrates from endometrial or rectal adenocarcinomas were analyzed for human papillomavirus (HPV) DNA by polymerase chain reaction with consensus and type-specific primers. Sixty-four percent (16 of 25) of the primary carcinomas and 20% (one of five) of the secondary infiltrates were positive for HPV types 16 and/or 18 DNA. Among the primary tumors HPV DNA was found in 80% of the endocervical cell-type tumors and in 60% of the endometrioid tumors, whereas two undifferentiated scirrhous carcinomas, one clear cell carcinoma, and one serous-papillary tumor were HPV negative. Human papillomavirus-positive patients were younger than HPV-negative patients (mean ages, 49.2 v 64.2 years). Our results indicate that papillomavirus play a major role in the etiology of cervical adenocarcinomas, at least in premenopausal women. However, in contrast to other studies, HPV type 18 was not the predominant type of HPV, HPV types 16 and 18 occurring with similar frequency in our patients.

RESUMO

Surgical specimens of 80 ovarian tumors of borderline malignancy (OTBM) were investigated by scanning DNA cytophotometry. Diploid or euploid DNA histograms were found for 21 tumors, whereas 59 OTBM showed noneuploid or aneuploid DNA patterns. All patients were followed-up after surgery for at least 3 years (mean observation period, 6.7 years). Follow-up showed 11 cases of recurrent disease and 6 deaths. DNA findings and several other morphologic and clinical details (including patient age, histologic type and stage of disease, and extent of therapy) were correlated to the postoperative course. Statistical analyses disclosed that, of these parameters, only DNA content significantly affected prognosis. Recurrences and deaths resulting from tumor exclusively were observed among patients with noneuploid or aneuploid OTBM, whereas none of the diploid or euploid tumors recurred (P less than 0.05). DNA cytophotometry thus might be regarded as an effective complementary means to assess the prognosis of individual OTBM cases.

RESUMO

A total of 34 surgical specimens, obtained from 13 patients with ovarian tumours of borderline malignancy (OTBM), were investigated by conventional histology, immunocytochemistry and DNA cytophotometry. The lesions were obtained by primary ovarian surgery or second-look procedures and altogether comprised 19 (single and bilateral) OTBM, 8 cases of endosalpingiosis, 4 in situ and 2 invasive peritoneal implants and 1 overt adenocarcinoma. The morphological findings were related to follow-up data, which showed neoplasms with clinically malignant behaviour in 2 patients. The histology of the extra-ovarian manifestations was not associated with their immunocytochemical properties or with their DNA content. There were no correlations between the evolution of disease and microscopical features but the clinical course appeared to be linked to the DNA content of the extra-ovarian lesions, which was of greater prognostic importance than DNA ploidy of the ovarian tumours. Recurrence-free survival was noted in all 5 patients with diploid or euploid extra-ovarian proliferations, while the 2 clinically malignant cases fell into the group of 3 patients with noneuploid or aneuploid specimens. DNA estimations may be a methodology which increases the prognostic value of second-look procedures in OTBM patients.

RESUMO

1,135 patients were subjected to conservation treatment of the breast between 1972 and April 1990. The probability of survival without relapses and metastases is 82.2% (5 years) or 72.1% (10 years), respectively. Local recurrence from relapses is 94.8% (5 years) or 88.9% (10 years), respectively. 31 patients developed an intramammary relapse, whereas 3 presented a renewed ductal in-situ manifestation, that was not considered to be a relapse. An unfavourable prognosis in respect of the rate of local relapses is considered to be dependent upon the size of the tumour. Other unfavourable factors are youthful age, concomitant DCIS formations, lymphangiosis carcinomatosa and "incomplete" resection (i.e. not including healthy tissue surrounding the tumour). These various "risk factors" are discussed on the basis of the literature and the authors' patient material.

RESUMO

Thirty-five female patients with congenital adrenal hyperplasia (CAH) were compared to a group of 16 healthy sisters in regard to gender-related behavioral patterns, present attitudes, and plans for the future. A semi-structured interview with the subjects, ages 11 to 41 yr, and their mothers concentrated on four to five age stages. Results of retrospective data from single items as well as from several related composite scales ("interests and behavior," "appearance," "overall scores") revealed significant group differences: Both in mother-assessment and self-assessment, CAH patients showed a "more masculine" orientation than their sisters, but this was far from consistent across all age stages, especially for single items. Unexpectedly, the gender-behavior differences between CAH patients and sisters did not hold for certain items and scales of "social behavior" (e.g., assertiveness, dominance, acceptance in peer groups) and, in contrast to some of the existing literature, also not for "high-energy expenditure." With regard to expectations for the future, CAH patients had less of a "wish to have their own children" and a higher preference for "having a career versus staying at home." Age, socioeconomic status, intelligence, and presence or absence of a sister as possibly intervening psychosocial/demographic factors could not explain the group differences in behavior. Degree of genital masculinization (Prader stages) or "onset and quality" of therapy as measures of pre- and postnatal androgenization, respectively, could also not account for the degree of the "more masculine" orientation in the CAH group. Nevertheless, the overall results are compatible with earlier findings on the masculinizing effects of prenatal androgens on behavior in humans and point to a time period after sexual differentiation of the genitalia and before birth as the most likely one for the effects of prenatal hormones on behavioral masculinization in humans.

RESUMO

The salt-wasting (SW) and simple-virilizing (SV) forms of congenital adrenal hyperplasia (CAH) are characterized by distinct prenatal hormonal milieus. To test whether these hormonal milieus differentially influence the development of a "more masculine" behavioral pattern in female CAH patients (Dittmann et al., 1990), SW patients (N = 13) were compared both to SV patients (N = 20) and healthy sisters of both groups (N = 16). The data are based on semi-structured interviews in which subjects (11-41 yr) and mothers were asked about aspects of "Gender-related interests and behavior," "Level of activity," "Social behavior," (reflecting e.g., assertiveness, dominance, and acceptance by peer groups) and "Appearance"; these areas of interest were represented by composite scales. On most scales, and by both mother-assessment and self-assessment, SW patients differed significantly from both SV patients and sisters in having a "more masculine" orientation. SW patients also showed a higher "Level of activity." These SW group results probably account for much of the CAH/sister differences reported in the companion article (Dittmann et al., 1990). In contrast, SV patients differed from the sister sample on only a few scales. There were no significant differences between SV and SW subjects in the degree of virilization of the external genitalia (indicating no group difference in prenatal androgenization). SW patients were treated "earlier" and "better" after birth (indicating less postnatal androgenization). However, these medical conditions, as well as several psychosocial/demographic variables, could not explain the group behavioral differences. These results do not support a primarily psychosocial explanation of behavioral development in CAH patients, especially those with the SW condition; they rather suggest differential organizational effects of two different hormonal environments (SV vs. SW) during critical periods of prenatal CNS development.

RESUMO

Plasma membrane fluidity of intact nonmuscle cells from patients with myotonic dystrophy (MyD) was determined by fluorescence anisotropy measurements. Anisotropy values of the probe diphenylhexatriene were decreased in patient mononuclear cells (0.163 +/- 0.017, n = 13) versus controls (0.181 +/- 0.013, n = 13, P less than 0.01) and in patient platelets (0.087 +/- 0.017, n = 9) versus controls (0.137 +/- 0.015, n = 9, P less than 0.001) indicating increased plasma membrane fluidity in patient nonmuscle cells. Vasopressin plasma concentrations were increased in patients (7.4 +/- 2.1 pg/ml, n = 12) versus controls (4.5 +/- 1.4 pg/ml, n = 22, P less than 0.0005), whereas serum osmolality was normal. These data are compatible with a decreased vasopressin sensitivity in MyD patients. Specific binding of 125I-labelled vasoactive intestinal peptide (VIP) was decreased in patient mononuclear cells (2.9 +/- 0.9%/10(6) cells, n = 8) versus controls (5.2 +/- 1.6%/10(6) cells, n = 9, P less than 0.005) and receptor affinity for VIP was decreased in patient mononuclear cells (Kd = 0.26 +/- 0.05 nM, n = 8) versus controls (Kd = 0.19 +/- 0.02 nM, n = 9, P less than 0.005). In nonmuscle cells of MyD patients, increased membrane fluidity correlated with decreased receptor availability. This might explain the various endocrine defects described in MyD patients.
