[Treatment of the contralateral breast in breast reconstruction. Nipple-areola reconstruction].

The final objective of breast reconstruction is to equalize as far as possible the appearance between the reconstructed breast and the contralateral breast. To this end, once the new breast monticle has been obtained through different techniques of breast reconstruction, we employ a different series of surgical techniques that allow us to obtain symmetry. In this way, we act on the one hand on the contralateral breast (either increasing it, reducing it or raising it), and on the other we act on the reconstructed breast, recreating a new nipple-areola complex, which will complete the reconstruction by giving this breast a more real and suitable appearance.

Outcomes of clinical and surgical assessment of women with pathological nipple discharge.

There is no consensus about the diagnostic approach to pathologic nipple discharge (PND). We hypothesize that lactiferous duct excision (microdochectomy) or image-guided biopsy are safe and effective means of diagnosis of PND. Eighty-two patients with PND underwent history and physical exam followed by breast sonography and mammogram. Image-guided biopsy was done if imaging studies were positive, whereas microdochectomy was done if normal. Discharge was unilateral (96%), bloody (79%), and spontaneous (62%). The sensitivity, specificity, positive and negative predictive values for the detection of neoplasia were 0.07, 1.0, 1.0, and 0.4 for mammography and 0.26, 0.97, 0.91, and 0.48 for sonography, respectively. Tissue diagnosis revealed papillary lesion (57%), mammary duct ectasia (33%), breast cancer (5%), and inflammatory/infectious (5%) causes. Hemorrhagic discharge associated with pregnancy or infections was managed successfully without surgery. After a median follow-up of 18 months, no PND recurrence was seen, but one patient developed cancer in a different location after diagnosis of atypical ductal hyperplasia. In conclusion, imaging studies provide confirmatory information and a biopsy target when positive. Negative imaging does not reliably exclude neoplasia or malignancy. Microdochectomy provides a sensible and effective approach in the workup of patients with PND.

Microbiological and biochemical assessment of the surface area of breast nipples and breast milk of lactating women in Calabar, southeastern Nigeria.

Microbiological and biochemical analyses of 59 breast nipple swab samples and 15 manually expressed breast milk samples of lactating mothers aged 15 to 40 years, was carried out using standard procedures. The incidence of bacterial species in swab samples was Staphylococus aureus (63.8%), Streptococcus sp (25.5%), Escherichia coli (6.4%) and Klebsiella sp (4.26%), indicating the poor sanitary status of the lactating mothers. S. aureus was recovered from only 1 (6.7%) of the milk samples, indicating that breast milk is relatively sterile. The nutritional values for the breast milk were 22.5 mg/ml (protein), 0.3 mg/ml (calcium), 3.5 mg/ml (sugar) and 300 microg/ml (vitamin A) in age group 15-20 years, and 16.4 mg/ml (protein), 0.16 mg/ml (calcium), 1.8 mg/ml (sugar) and 100 microg/ml (vitamin A) in the age group 36-40 years. In conclusion, the nutritive and antimicrobial properties of breast milk decrease with increasing age of lactating mothers. The need for public health enlightenment of lactating mothers regarding hygiene, and the provision of oral vitamin A supplement to infants, is discussed.

Detection of breast cancer biomarkers in nipple aspirate fluid by SELDI-TOF and their identification by combined liquid chromatography-tandem mass spectrometry.

Screening mammography is the most effective tool available for breast cancer detection. While screening mammography saves lives, it has intrinsic problems that limit further improvement. We hypothesize that protein biomarkers in nipple aspirate fluid (NAF) may separate the cancer from the non-cancer state, and therefore can be used for breast cancer detection. In this study the proteins in NAF were analyzed by surface-enhanced laser desorption ionization coupled to time-of-flight mass spectrometry (SELDI-TOF) in the m/z 5,000-85,000 range. Two methods were used to normalize spectra. Then differentially expressed signals that separate cancer from non-cancer conditions were selected by two specifically developed statistical algorithms. Proteins of interest were identified by combined liquid chromatography-tandem mass spectrometry. A set of 8 markers were identified which collectively gave 63% sensitivity, 89% specificity and 76% accuracy for distinguishing cancer from non-cancer. Further improvements in the specificity and sensitivity of this strategy could come from the development of methods for more precise quantification of the biomarkers of interest and also from focusing on the low abundant components that are not evident when unfractionated NAF is analyzed directly.

Nipple sparing mastectomy with immediate breast reconstruction: a short term analysis of our experience.

Breast cancer surgery has greatly changed over the past decades; nowadays skin-sparing mastectomy (SSM) and immediate reconstruction is considered a valid oncological option to achieve good aesthetic results. The success of SSM led to several studies aimed to investigate NAC involvement whose removal increases the patient's sense of mutilation. In this study the Authors investigate the incidence of recurrences in nipple sparing mastectomy (NSM) comparing it with the other techniques to assess the actual risk of tumor involvement of the NAC; besides, they analyse the patients' satisfaction and the NSM impact on quality of life through the utilization of a questionnaire. Clinical complications, aesthetic as well as oncological and psychological results have been analysed. They conclude that in selected cases NSM can be performed without additional risks because the incidence of recurrence after NSM is similar to that of radical mastectomy. Moreover, the aesthetic and psychological outcome are considered positive by the patients.

[Selective galactophorectomy for mono-orificial nipple discharge without associated mass: technique and results. Apropos of seventy-three cases].

A single duct mammary discharge is a sign of an underlying disease: inflammatory, benign proliferative disease or even cancer. Selective resection of a ductolobular tree insures appropriate diagnosis and causative and definitive treatment of the discharge. Mammogram is essential. Galactography is quite usefull and reliable but may be unindicated or contraindicated. Surgery includes catheterization of the hole, methylene blue dye staining of the duct, circumareolar or radial incision, dissection, pyramidal resection of the whole galactophoric tree and closure with a retracting suture of the nipple. Woman's age, color of the discharge, pre-operative galactography suggest the diagnosis which has been in our series of 73 cases an inflammatory process in 53.4% of cases, a benign proliferative in 42.5% of cases and an epithelioma in situ in 4.1% of cases. The 46 cases of serous, serosanguinous or sanguinous discharge were due to an inflammatory process in 15 cases (32.6%), a benign proliferative in 28 cases (60.9%) and an in situ carcinoma in 3 cases (6.5%).

[Leiomyoma of the nipple (a case report and review of the literature)].

The leiomyoma of the nipple is a very rare affection. No more than 20 cases are reported in the literature of the last 50 years. This neoplasm presents a difficult differential diagnosis with the remaining phlogistic and neoplastic breast diseases. We report a personal case with a review of the literature.

Florid papillomatosis of the nipple: immunohistochemical and flow cytometric analysis of two cases.

The immunohistochemical and DNA profiles of two cases of florid papillomatosis of the nipple (FPN) were compared with the immunohistochemical and DNA profiles of mammary intraductal carcinomas (IC) to assess the relationship between these two proliferative neoplasms. Both examples of FPN were circumscribed papillary tumors in the subareolar breast that showed cytologic atypia, intraductal necrosis, and a distinct myoepithelial cell layer. An antibody to muscle-specific actin (MSA) decorated a continuous myoepithelial layer in one case that was confirmed by electron microscopy. MSA showed patchy, discontinuous staining of apparent myoepithelium in the ICs. Flow cytometric analysis showed that both FPN lesions were diploid, rapidly proliferating lesions with S-phase fractions of 10.9% and 34.4%. One IC was aneuploid, and the five diploid neoplasms showed S-phase fractions ranging from 6.4 to 15.8%. In FPN many epithelial cells stained intensely for S-100 protein, but each IC also showed at least focal expression of S-100 protein. One case of FPN was focally positive for gross cystic disease fluid protein 15 (GCDFP-15), but neither stained for tumor-associated glycoprotein-72 (TAG-72) nor for the product of the c-erbB-2 oncogene. In comparison, three ICs expressed focal GCDFP-15, four stained for TAG-72, and one was positive for the c-erbB-2 oncogene product. These preliminary observations suggest that the tandem proliferation of epithelial and myoepithelial cells and the preservation of a normal structural relationship between the two appears to separate FPN from intraductal carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

[Nipple discharge without palpable tumor. Apropos of 46 cases].

The authors report 46 cases of nipple discharge without any palpable lesion. The diagnostic is made, most of the time, by 3-views bilateral mammograms. The place of other examinations (ultrasonography, galactography) is reported. The cytology of the discharge, as well as its macroscopic appearance (bloody, serous or greenish), determine the surgical indications. Quadrantectomy centered around the discharging duct, is the procedure of choice in this disease, at the interface between diagnostic and treatment, in fact, if benign tumors (papillomas) or non tumoral diseases (fibrocystic mastopathy and duct ectasia) predominate, invasive or in-situ malignant lesions represent 13 p. cent of these 46 discharges, justifying the significance of this clinical sign.

[Differential diagnosis of nipple discharge].

An analysis of results of contrast mammography in 42 women having spontaneous, persistent and unilateral discharge from the nipple of the breast of serous, serous-hemorrhagic and hemorrhagic character was made. The cause of the discharge was found to be intraductal papillomas and cystadenopapillomas in 55% of the cases, breast cancer--in 2% which were not diagnosed by noncontrast mammography.

[Activation of the pituitary-adrenal axis by nipple suction in the lactating rat].

The response of the pituitary-adrenal axis to suckling in lactating Rats is dependent on two factors: 1. a psychic factor, which is identical by its effects to the psychological stress of the strange environment (transitory increase of plasma corticosterone and no significant modification of the content of ACTH in the two lobes of the pituitary); 2. a specific factor namely the stimulation of the nipples, which is distinguishable from the psychic factor by a longer release of corticosterone by the adrenals and a durable and significant decrease of the content of ACTH in the pars distalis.

[Contrast mammography in spontaneous bloody secretion from the nipple].

43 women with spontaneous bloody nipple discharge were examined by galactography performed with water soluble contrast medium. The purpose of this study was to evaluate the use of galactography in these patients, to localize the cause of this particular type of discharge and to register the therapeutic consequences of the findings. Surgical resection was carried out in all cases where galactography showed intraductal pathology. The remaining patients (except for four who also underwent surgery) were observed without treatment. No sign of carcinoma was found in a follow-up examination of the non-operated patients after two to four years. The results show that galactography can be suitably used to demonstrate and localize intraductal pathology, and may therefore be of importance in the preoperative investigation of spontaneous blood-stained secretion.

Chromogalactography preceding ductal-lobular unit excision for nipple discharge--with special reference to diagnostic galactography and histology.

Between 1981-88, 223 surgical interventions were performed in cases of pathologic breast secretion after exclusion of extra-mammary aetiology. The milk duct was identified by pre-operative chromogalactography, followed by a selective excision of the ductal-lobular unit. In 36 cases (16.1%), however, neither spontaneous nor provocable secretion remained after diagnostic galactography, so that a segment resection was required. In all tissue specimens, the cause of the pathologic secretion was found histologically; most often, it was fibrocystic disease or solitary intraductal papilloma (21.5% each). In 32.3% of the specimens, findings with a prospective significance (papillomatosis, carcinoma in situ or invasive carcinoma) were discovered and further operative treatment was initiated. The colour of the discharge allowed no prediction of the histological findings. In 28.6% (8/28) of the carcinomas, secretion was bilateral. In 46.4% of the specimens containing carcinoma, papillomatosis was also detected; vice versa, papillomatosis was associated with carcinoma in 22.8%. The recurrence rate of 1.6% indicates the efficiency of this method in removing the pathology. The diagnostic value of galactography for the prediction of findings with a prospective significance was considerably reduced by a rate of 37.5% false-negatives; therefore, we have decided to omit diagnostic galactography in our patients. Now, provided extra-mammary causes of the nipple discharge have been excluded and mammography has been inconspicuous, a selective excision of the ductal-lobular unit is performed after preoperative chromogalactography.

Changes in the Bishop score induced by manual nipple stimulation. A cross-over randomized study.

Bishop score changes, by a cross-over, randomized study, were evaluated in 60 primigravidas at term, not yet in labour, who performed nipple stimulation for 45 minutes three times a day for three days. Results showed that changes of Bishop score in the treated groups were statistically highly significant, in comparison to control groups. A greater frequency in the onset of labour was also remarked.

Conservative management in full-thickness nipple-areolar necrosis after subcutaneous mastectomy.

Nipple-areolar necrosis is a known and expected complication in a small percentage of patients undergoing subcutaneous mastectomy, especially with concomitant mastopexy or in smokers. Impending ischemia or congestion of the areola can often be ameliorated by simple maneuvers such as suture release. When full-thickness necrosis occurs, conservative management with essential debridement, dressings, and careful wound hygiene alone will often yield a surprisingly good result, requiring little or no revisional surgery.
