These associations have been more consistent for vegetables than for fruits and for green vegetables in particular medicine 751 m purchase synthroid toronto. However medicine on time buy generic synthroid, in the pooled analysis of eight large prospective studies (7 treatment myasthenia gravis discount synthroid 125mcg fast delivery,377 cases among 351 treatment trichomonas purchase synthroid now,825 women) treatment 5th metatarsal fracture cheap synthroid 200mcg overnight delivery, only weak and nonsignificant associations were seen with increasing consumption of fruit and vegetables (498) 247 medications generic synthroid 50 mcg otc. A thorough search among specific fruits and vegetables and botanical groups did not reveal any significant associations. A similar lack of association was seen in a large multicentered cohort study in Europe (499). In a metaanalysis of prospective studies that included over 16,000 cases of breast cancer, similar weak inverse associations to the earlier pooled analysis were seen, but the associations for total fruits and vegetables were statistically significant (500). Recent findings suggest that a reduction in risk of breast cancer with higher intakes of fruits and vegetables may be specific for estrogen receptor negative tumors (501); the relative risk comparing highest with lowest quintiles of vegetables intake was 0. Associations between red meat consumption and risk of breast cancer have been reported sporadically (504). However, in the pooled analysis of large cohort studies (7,379 cases) (505), no association was seen with consumption of red meat, white meat, or dairy products. In an analysis that retrospectively assessed degree of cooking (506), consumption of well-done red meat was associated with breast cancer incidence. In a prospective study among premenopausal women, intake of red meat was associated with a two-fold increase in risk of breast cancers that were positive for estrogen and progesterone receptors (373). Fat per se was not associated with breast cancer risk, suggesting that Coffee and Tea Considerable speculation that caffeine may be a risk factor for breast cancer followed a report that women with benign breast disease experienced relief from symptoms after eliminating caffeine from their diet. Similarly, no evidence for an association between tea consumption and risk of breast cancer has been seen in epidemiologic studies (486). Thus, the epidemiologic evidence is not compatible with any substantial increase in breast cancer risk associated with drinking coffee or tea. Phytoestrogens Phytoestrogens in soy products have attracted scientific and popular attention, in part because they are highly consumed in Asian countries, such as Japan and China, which have low rates of cancer (487). Thus, these substances may act like tamoxifen by blocking the action of endogenous estrogens to reduce breast cancer risk. Dietary supplementation with a large amount of soy protein slightly lengthened menstrual cycle (488), which would be predicted to decrease breast cancer risk only minimally. Also, soy protein consumption is not the primary explanation for low rates breast cancer in Japan and China because rates are similarly low in other parts of China, elsewhere in Asia, and in many developing countries where soy and related foods are not regularly used. In case-control studies in Singapore (489) and China (490), and in Asian Americans (491), intake of soy products, particularly during adolescence, was associated with lower risk of breast cancer. However, in two other case-control studies in China (492,493) and in a prospective study from Japan (494), little relation was seen. Approximately half of this cohort also completed a detailed questionnaire about their diet during high school; consumption of red meat during this period was also associated with risk of premenopausal breast cancer (375). This finding is consistent with a greater susceptibility of breast tissue to carcinogens during this period of life but needs replication; unfortunately, few such studies exist. Although a protective effect of fish consumption has been suggested in a few studies, the overall evidence from case-control and cohort studies suggests little relationship (505). Intake of nuts and legumes has received limited attention in reports on diet and breast cancer, but in general, no relation has been seen (471,486). Dietary Patterns Overall dietary patterns have been examined in relation to breast cancer incidence. Diet and Breast Cancer Survival Regardless of whether diet is related to the occurrence of breast cancer, if postdiagnosis diet were related to risk of recurrence or survival, then dietary modifications might assist in breast cancer treatment. In one study of diet after diagnosis (albeit in the 1 to 5 months immediately after the diagnosis), no association was seen between dietary fat intake and survival (507). Among premenopausal women, higher consumption of butter, margarine, and lard after diagnosis was associated with greater likelihood of reoccurrence (508). In a larger study, diet was assessed before and after breast cancer diagnosis (509). Greater fat intake after diagnosis was associated with a nonsignificantly worse survival outcome. However, higher protein consumption, mainly from poultry, fish, and dairy sources, was related to a better prognosis, even after controlling for protein consumption prior to diagnosis. Although overall dietary patterns after diagnosis were not associated with breast cancer mortality in this cohort, a prudent dietary pattern was associated with lower mortality, and Western pattern with higher mortality, from causes other than breast cancer (510). Similarly, higher intake of trans fat and saturated fat after diagnosis of breast cancer was associated with higher overall mortality, although not breast-cancer-specific mortality (511). This is important because with early diagnosis and good treatment, the large majority of women will survive their breast cancer, but they remain at risk for diseases of women in general. In a recent pooled analysis, alcohol consumption after diagnosis of breast cancer has overall not been associated with survival (512), although a marginally significant increase in recurrence was seen in postmenopausal women. Also in a pooled analysis, higher soy consumption after diagnosis was associated with a nonsignificantly lower risk of breast-cancer-specific mortality, and a significantly lower risk of breast cancer recurrence (513). Also, regular use of supplements of vitamin E and vitamin C was associated with lower risk of breast cancer recurrence (514). Several randomized trials have been conducted among women with early-stage breast cancer to determine the effects of dietary change on recurrence or mortality. In one trial, 2,437 women with breast cancer were randomized to a low fat diet or their usual diet and followed for an average of 5 years (515). Dietary fat intake was reduced to 33 grams per day in the intervention group compared to 51 grams per day in the control group, and weight was also six pounds lower in the intervention group. These results were suggestive of a possible benefit of the intervention, but not conclusive, and it is not possible to know whether any benefit is due to reduction of fat intake or lower weight gain (potentially due to the intense intervention because the overall evidence does not support a specific benefit of fat reduction on body weight). In another trial among 3,088 women, one group was assigned to a diet high in fruits, vegetables, and fiber and low in fat (516). The increase in fruit and vegetable consumption was large, and documented by a 50% increase in blood carotenoid level, but the reported difference in fat intake was small (-15%), so this study primarily tested the benefit of increasing fruit and vegetable intake. Summary of Diet and Breast Cancer the role of specific dietary factors in breast cancer causation is not completely resolved. Enthusiasm for the hypothesis that dietary fat intake was responsible for the high rates of breast cancer rates in Western countries was based largely on the weakest form of epidemiologic evidence-ecologic correlation studies. Results from prospective studies and randomized trials do not support the concept that fat intake in middle or later life has a major relation to breast cancer risk. Excess energy intake in relation to physical activity during adulthood, which accelerates growth and the onset of menstruation during childhood, leads to weight gain in middle life and thus can contribute substantially to breast cancer risk. These effects of energy balance clearly account for an important part of international differences in breast cancer rates. Some evidence suggests that carotenoids or other compounds in carotenoid-rich foods may reduce breast cancer risk modestly, but these findings are not conclusive and deserve further consideration. Alcohol intake, even at very low levels, is a well-established risk factor for breast cancer, and studies demonstrating that even moderate alcohol intake increases endogenous estrogen levels provide a potential mechanism, thus supporting a causal interpretation. Diet during childhood has been relatively unstudied, but recent evidence suggests that higher intake of soy products and lower intake of red meat during this period may reduce risk of breast cancer. Other recent findings suggest that characterization of breast cancers by hormone receptor status, and potentially other features, may be important in studies of diet. Although our understanding of diet and breast cancer is incomplete, evidence can be considered conclusive that breast cancer risk can be reduced by avoiding weight gain during adult years and by limiting alcohol consumption. Although less conclusive, some evidence suggests that breast cancer risk can be modestly reduced by limiting intake of red meat during early adult life, by replacing saturated fat with monounsaturated fat, and by consuming more fruits, vegetables, and whole grains (which characterizes the Mediterranean dietary pattern). Even with some uncertainty regarding their relationships with breast cancer, these dietary behaviors can be strongly recommended because they will substantially reduce risks of coronary heart disease (354) and diabetes (517). A number of potential mechanisms have been proposed including changes in menstrual cycle characteristics, lowering sex hormones and insulin-like growth factors, and/ or improving immune function (519,520). The mechanisms by which physical activity reduces exposure to hormones vary by period of life. This effect of activity at young ages may be reflected in lower body weight and body fat, both of which are determinants of delayed menstruation (399,522). A later menarche is associated with a later onset of regular ovulatory cycles and lower serum estrogen concentrations during adolescence (525). Once menstruation has been established, anovulatory and irregular menstrual cycles may be more common among moderately and strenuously active women than among inactive women (396,524,526), although there is disagreement regarding the degree to which the intensity of physical activity influences menstrual abnormalities (527). Further, a substantial degree of ovarian dysfunction may occur even among physically active women who appear to have normal menstrual cycles (528). However, there are a number of aspects regarding this association that remain unclear. Methodologic differences in physical activity assessment are likely to have contributed to inconsistencies in study results. Studies have differed in the ages at which physical activity was assessed, methods for measuring intensity, frequency, and duration of physical activity, definition and categorization of physical activity levels (including consideration of only recreational, or recreational and occupational, activity), and age at breast cancer diagnosis. However, results have varied even among studies that have tried to assess physical activity at similar times in life using similar tools. One of the strongest reductions in breast cancer risk associated with increased physical activity was reported in a population-based case-control study of women younger than 40 years (538). This was the first study explicitly devoted to the relationship between physical activity and breast cancer, and it was also the first to use a detailed physical activity assessment instrument to quantify the average number of hours per week of recreational physical activity over the reproductive life span, beginning at menarche. Activities such as housework, gardening, and easy walking not for the explicit purpose of physical exercise were not counted in the measure of physical activity. These researchers concluded from their various analyses that lifelong physical activity is the critical exposure of interest with regard to breast cancer risk. In one of these studies (547), results support those reported above, with reduced risk of breast cancer in premenopausal women with higher lifetime physical activity. In contrast, another study found no association between activity in earlier periods of life and postmenopausal breast cancer (548). Types of activity are widely varied across individuals, as well as across studies. Broad categories of recreational, household, and/or occupational activity have been assessed in many studies. The findings of inverse associations with household and occupational physical activity, but not with recreational activity, suggest that residual confounding by sociodemographic and reproductive factors are at least partly responsible for the observed inverse relationships. Among types of recreational activities, some studies have observed stronger associations for more moderate or vigorous activities, compared with less intense activities (555). However, even brisk walking appears to be beneficial, as was reported in one study (556). It has been hypothesized that high levels of physical activity during adolescence are particularly important with respect to influencing breast cancer risk. However, other studies that have examined the association between physical activity during adolescence and breast cancer risk have found little evidence for a protective effect. Indeed, some studies have observed stronger associations with more recent, or later in life, physical activity. In contrast to the detailed measurement of lifetime physical activity employed by some of the studies mentioned earlier, a relatively simple measure of physical activity was used in a prospective cohort study of Norwegian women aged 20 to 54 years at baseline (558). Over a period of 3 to 5 years, women were administered two surveys about their current patterns of physical activity during leisure hours; they were asked to rank themselves on a four-point scale with respect to activity level. Several recent studies have examined physical activity by tumor type and survival. The association with invasive breast cancer appears consistent across several studies, while an association with in situ disease has been observed in some studies but not others (559,560). A large pooled analysis of physical activity after breast cancer diagnosis reported reduced breast cancer mortality with at least 2. There would be obvious public health significance to an association between a modifiable lifestyle risk factor such as physical activity and breast cancer. Despite the wealth of data on the subject, it is difficult to come to a clear conclusion on the topic given numerous methodologic issues. These issues include the resolution of whether a critical lifetime period exists during which increased physical activity exerts its strongest effect on breast cancer risk, or whether lifetime physical activity is the critical exposure of interest for most women. It is also unclear if the effects of physical activity on breast cancer differ in particular subgroups of women. A second important issue relates to the quantification of physical activity and how information on frequency, intensity, duration, and time span of activity can and should be combined into a single measure or a small number of measures that can be readily modeled. In case-control studies, random error in recall of past activity levels that is not dependent on disease status would be expected, on average, to dilute any inverse association that might truly exist. If errors are differential by disease status, however, findings may be biased in either direction away from their true point estimates. A fourth issue concerns the need to consider recreational, occupational, and household physical activity together. In studies of physical activity, the potential exists for confounding by reproductive characteristics for several reasons.

Epiphora (a rare postoperative problem) Surgical Steps A nasal endotracheal tube is placed on the unaffected side and fixed contralateral to the lesion symptoms nausea headache cheap synthroid 150mcg with amex. The patient is placed in a reverse Trendelenburg position symptoms 8 dpo bfp purchase synthroid 50 mcg with visa, and the head is slightly rotated contralateral to the affected side medications gerd purchase synthroid master card. The incision starts at the philtrum treatment programs discount synthroid 25 mcg line, close to the columella symptoms 10 dpo purchase 150mcg synthroid with amex, and continues around the nasal vestibule and ala and enters the nasolabial crease medicine 81 buy synthroid without a prescription, extending superiorly along the nasofacial junction. The superior end of the Weber-Ferguson incision is located at the midpoint between the medial canthus and the nasal dorsum. The incision is designed so that it is medial to the attachment of the medial canthal ligament. Careful cross-hatching of the incision is mandatory to achieve accurate wound closure. Extra care needs to be taken, as the skin in this region is very delicate and may be easily damaged. Dissection continues on a broad front from the zygomatic arch down to the piriform sinus. During this initial dissection of the orbital region, the orbicularis oculi muscle is preserved in continuation with the eyelid. The orbicularis oculi is retracted, revealing the inferior orbital rim, on which a cut is made, and the periosteum is elevated horizontally along the orbital floor, as far as possible. Dissection continues along the anterior maxillary wall, and the infraorbital neurovascular bundle is encountered and transected. By maintaining this portion of the maxilla, improved cosmesis, and better support for the dental obturators is offered. Malignant hard palate lesions extending to the inferior or medial maxillary wall 2. At that point, the incision turns laterally, dividing the hard from the soft palate, reaching the posterior end of the maxillary tuberosity. If possible, the hard palate incision is performed a few millimeters lateral to the midline to create a mucoperiosteal flap, which will be used to cover the remaining free palatal edge. Another incision is created along the gingivolabial sulcus and continues within the gingivobuccal sulcus, until it is connected with the previous incision, behind the maxillary tuberosity. During the osteotomy stage, brisk bleeding is to be expected; therefore, the procedure should continue in an expeditious fashion. The zygomatic arch is divided, releasing the maxilla from the zygoma, the exact position depending on the site and extent of the tumor. The check flap (arrows), contralateral hard palate (asterisk), preserved infraorbital rim (arrowheads) and nasopharynx can be seen. Again, the extent of the orbital wall removed depends on the site and size of the tumor. In some cases, it is even possible to preserve a thin section of the infraorbital rim. The maxillary alveolar ridge, the hard palate, and the junction with the soft palate are transected along the previously performed incisions. Care is taken to preserve the mucoperiosteal flap created previously that will be used to cover the exposed contralateral maxillary edge. A final osteotomy is performed behind the maxillary tuberosity, releasing the maxilla from the pterygoid plate. External Approaches 827 the specimen is mobilized with a rocking motion and removed en bloc. A split-thickness graft is harvested from the prepared donor site and placed over the defect, including the inner surface of the cheek flap. A nasal pack is inserted, and the cheek flap is repositioned; closure is performed in layers. A temporary dental obturator is secured in place to stabilize the nasal packing and to restore the facial contour. However, due to lack of support and local tissue changes, this can be problematic. Diplopia (usually associated with trochlear trauma or loss of structural support, usually transient) 5. Infraorbital or superior alveolar nerve paresthesia/ anesthesia (usually transient) 10. A variety of cosmetic problems can present postoperatively, ranging from disturbance of the facial contour to visible facial scarring (usually concealed within natural creases). Medial canthal webbing Orbital Exenteration In cases of tumors extending beyond the maxillary antrum and invading the orbital contents, in addition to total maxillectomy, eye exenteration has to be performed. It should be noted that eye resection is warranted only in cases of curative procedures and not for palliative reasons. The incision performed is a Weber-Ferguson, with the addition of a subciliary and superciliary extension joining at the lateral canthus and encircling the eye. Following the total maxillectomy, dissection proceeds by releasing the eyelid skin, remaining superficial to the orbicularis oculi and freeing the orbital rim circumferentially. The orbital periosteum is incised along the supraorbital rim, and dissection proceeds along the orbital roof toward the orbital apex. The optic nerve and the ophthalmic artery are transected at the orbital apex, and the orbital suspensory ligaments are divided. Brisk bleeding is encountered usually at this stage that needs to be controlled accordingly. Inferiorly, the orbit remains connected to the maxillary specimen to remove the tumor en bloc. Subsequently, osteotomies are performed, and the specimen is released from the orbit. Postoperatively, the defect can be restored after healing is completed with an eye prosthesis. Eye complications (epiphora, diplopia, and xerophthalmia) are very common if maneuvers are performed in this region, but they are usually transient. If the orbital contents are involved by the tumor, then an orbital exenteration could be performed; patients should be informed about the possibility of loss of sight and the cosmetic deformity that will result from this operation. It should also be noted that in some cases the exact extent of the disease cannot be defined prior to the procedure despite imaging; therefore, patients should always be warned about the possibility of eye loss. Postoperative Care Oral irrigation is performed as soon as feeding is initiated to improve oral hygiene. After removal of the nasal pack, regular nasal douching is initiated to remove further nasal crusting. In patients with male pattern baldness, the incision is located more posteriorly in the hair-bearing corona. The coronal incision goes down as far as the periosteum and is dissected to the supraorbital ridge and over the root of the nose. The scalp flap is pulled caudally on both sides, leaving behind the periosteum and the bone, thus preserving the supraorbital and supratrochlear vascular nerve bundles. To estimate the borders of the frontal sinus, a template from a fronto-occipital plain film radiograph can be used. When opening the frontal sinus bilaterally, the intersinus septum must be separated from the anterior frontal sinus wall. According to the pathologic-anatomical findings, the diseased tissue is then removed. Fractures must be exposed to their full extent and repositioned, and, if necessary, a dural lesion has to be repaired. With regard to the underlying disease and the frontal sinus mucosa, it has to be decided whether the frontal sinus can be preserved or whether cranialization or obliteration should be performed. If obliteration is indicated, the frontal sinus mucosa has to be removed completely, and the inner layer of the bony walls must be drilled away under microscopic view. Just macroscopic stripping of the mucosa leads in a high percentage of cases to inflammatory recurrences and mucoceles. It allows total removal of the mucosa, leaving the bony vascular channels open, which facilitates revascularization of fat, used for obliteration. In dangerous areas such as exposed dura or the orbital roof (notably, the periorbit), a diamond drill should be used. The mucosa in the region of the frontonasal ostium is inverted nasally, and the drainage opening is blocked with pinna conchal cartilage on one side covered by overlapping perichondrium and fixed with fibrin glue. Through this three-layered closure, the frontal sinus is securely isolated from the nasal cavity and the ethmoidal cells, respectively, and growth of mucosa into the sinus with the associated risk of mucocele formation is prevented. Abdominal harvested fat is placed by pieces into the frontal sinus, held together with fibrin glue, until the sinus cavity is completely filled. Finally, the periosteal bone lid is replaced and fixed with absorbable threads, wire sutures, or miniplates. At the end of the operation, the scalp flap is flipped back into place, two suction drainages are inserted, and the coronal incision is closed with single-stitch sutures. If reconstruction of the bony forehead is needed, many different grafts and implants can be used. There are autogenous bone and cartilage grafts, such as rib, scapula, iliac crest, calvarial bone (inner and outer table), and calvarial bone pedicled at the temporalis muscle. There are also alloplastic materials, such as titanium mesh or plates, polymethyl methacrylate, porous polyethylene, ceramic (hydroxyapatite, carbonated apatite), and biocement (Bioverit). In our experience, autogenous calvarial bone has been proven to be the most suitable material for the anterior frontal sinus wall. Usually, the graft is taken more anteriorly and medially if a flat portion of bone is required, and more laterally and posteriorly if a curvilinear piece is needed. For the transfer of calvarial bone grafts, three techniques exist: splitthickness calvarial graft, single-table calvarial graft, and calvarial bone flap. Patients should be followed at 3-month intervals in the first year to examine for instability, resorption, and infection of the reconstructed region. Indications Malignant anterior skull base tumors without and with intradural extension. Complications Infection of the calvarial graft has been reported as occurring in 1. The periorbit is dissected from superior, medial, and lateral walls and can be exposed back to the apex. The outline of the opening needs to be planned depending on the size of the frontal sinus and the extent of the tumor. Osteotomies are performed by an oscillating saw across the frontal bone, down to and along the orbital roofs, down the medial orbital wall, and along the nasomaxillary grooves just anterior to the lacrimal crest. Using chisels, the nasofrontal segment, including the whole frontal sinus, is elevated under direct vision, freeing the dura. Therefore, the dura over both frontal lobes is incised, followed by ligation of the sagittal sinus and dissection of the falx cerebri, which is finally cut. Subsequently, one has a good view over the olfactory grove with both olfactory bulbs and the tumor. With frontal lobe protection by surgical dressing, exposure can be extended down to the optic chiasm. Tumor removal is then performed by osteotomies of the anterior skull base laterally at the junction to the orbital roof and caudally at the planum sphenoidale under direct vision and protection of the Subcranial Approach According to Raveh the subcranial approach was first introduced by Raveh et al for treatment of traumatic disruption of the anterior skull base and published in 1981. This is accomplished by dural detachment from below with practically no frontal lobe retraction, the avoidance of facial incisions, and adequate dealing with the paranasal sinuses, especially cranialization of the frontal sinus. Caudal and lateral tumor extensions involving the nasal cavity, maxillary sinus, soft palate, and epipharynx are exposed by the same subcranial anterior route, obviating the need for conventional transfacial approaches, such as lateral rhinotomy and midfacial degloving. After complete exposure, osteotomies, and intracranial dissection, tumor removal can be achieved en bloc rather than in a piecemeal fashion. For reconstruction of the skull base defect, we recommend several layers of fascia lata (at least two, best three). The first layer of the simultaneously harvested fascia lata is tacked under the edges of the dura and carefully sutured in place. The repaired dural defect is then covered with a second layer of fascia applied against the entire undersurface of the ethmoidal roof, sella, and sphenoidale area. If the medial orbital walls have to be reconstituted, either fascia lata or Tutoplast fascia lata can be used. If the canthal ligaments have to be fixed, this can be accomplished by placing two nonabsorbable threads through both medial canthal ligaments, running underneath the nasofrontal segment. When the tumor involves the nasal bone or other fronto-orbital segments, a split calvarial bone graft can be used for reconstruction. Before replacing the osteotomized nasofrontal bone segment, the posterior frontal sinus wall is removed, as well as the mucosa of the entire frontal sinus. The bone segment is then repositioned in its original anatomical place and fixed using prebent titanium plates. The closure of the scalp is performed in the same way as the osteoplastic frontal sinus approach. Postoperative Care Postoperatively, patients are immediately transferred to the intensive care unit for 24 hours. Patients should be followed at 3-month intervals in the first year and then on a regular basis for at least 5 years. Postoperative radiotherapy or chemoradiation can start 6 weeks postoperatively at the earliest. Esthesioneuroblastoma and adenoid cystic carcinoma have the most favorable prognosis, with positive 5-year, disease-specific survival rates. However, in adenoid cystic carcinoma, the prognosis is determined mainly by distant metastases and slow perineural spread that diminish disease-specific survival to 40% after 15 years. Malignant melanomas show, along with undifferentiated carcinomas, the worst prognosis. Possibly also T3 tumors might be removable endonasally if they only superficially infiltrate the lamina papyracea and periorbit or the cribriform plate and dura, respectively.

Today medications rapid atrial fibrillation discount synthroid master card, many units incorporate ductography and ductoscopy into their management protocols symptoms 3 days dpo order synthroid canada, particularly in younger women medicine 5e order 125 mcg synthroid otc. The problem is how to treat a patient with nipple discharge in whom imaging medicine you cannot take with grapefruit buy synthroid 125 mcg otc, including ductography or ductoscopy and ductal lavage z pak medications cheap 100 mcg synthroid mastercard, fails to identify any serious lesion symptoms 11dpo order 50 mcg synthroid with amex. Some argue that as discharge from malignant disease is more likely to be bloodstained, there is no place for conservative management of bloodstained discharge and that all patients with bloodstained discharge should undergo duct excision unless investigation has identified a specific benign cause (16). A period of observation, particularly in younger women (35 years of age), is appropriate if the history of discharge is short but if spontaneous discharge persists (2 per week) at review 4 to 6 weeks later and the discharge can be expressed from a single duct on examination, then surgical excision is indicated to establish the cause of the discharge. Occasionally, the papilloma is so close to the nipple that it can be seen in the orifice of the duct at the nipple. A solitary papilloma is not thought to be a premalignant lesion and is considered by some to be an aberration rather than a true disease process. Differential Diagnosis of Nipple Discharge Physiologic Causes In two-thirds of nonlactating women, a small quantity of fluid can be expressed from the ducts of the nipple if the nipple is cleaned, the breast massaged, and pressure applied. This fluid is physiologic secretion and varies in color from white to yellow to green to brown to blue-black; it is thought to represent apocrine secretion, as the breast is a modified apocrine gland. This physiologic secretion usually emanates from multiple ducts, and the discharge from each duct can vary in color. It is commonly found after pregnancy and is often noticed after a warm bath or after nipple manipulation. The discharge is not usually spontaneous or bloodstained and no specific treatment is required. Multiple Intraductal Papillomas In approximately 10% of patients with intraductal papillomas, multiple lesions are found; usually, two or three occur, often in the same duct. The term multiple intraductal papilloma syndrome is reserved for the rare and distinctive group of patients in whom one duct system contains five or more large and often palpable papillomas with a peripheral distribution. Nipple discharge is less common than in Intraductal Papilloma A true intraductal papilloma develops in one of the major subareolar ducts and is the most common lesion causing a serous or bloody nipple discharge. In approximately half of women with papillomas, the discharge is bloody; in the other half, it is serous (9). Papillomas should be differentiated from papillary hyperplasia, which affects the terminal duct lobular unit and can also cause nipple discharge. Central papillomas consist of epithelium covering arborescent fronds of fibrovascular stroma attached to the wall of the duct by a stalk. The covering epithelium has a two-cell population, with a cuboidal or columnar cell lining covering an underlying layer of myoepithelial cells. In one study, multiple papillomas were reported to be associated with an increased risk of breast cancer, but any increased risk is almost certainly associated with areas of atypical epithelial hyperplasia rather than with the papillomas themselves (18). Repeated excision of papillomas in patients with multiple intraductal papillomas can result in significant breast asymmetry. One option in such patients is to excise such lesions using ultrasound guidance by percutaneous vacuumassisted biopsy. This provides sufficient material for the pathologist to assess whether lesions are benign and whether atypia is present. Some patients have multiple recurrent peripheral papillomas involving a whole ductal system and in such patients surgery to excise the affected ductal tree should be considered. Juvenile Papillomatosis A rare condition, juvenile papillomatosis, affects women between the ages of 10 and 44 years (19). Three of the 13 presented with nipple discharge; 2 had a palpable peripheral mass lesion, and the remainder had nipple discharge alone. Patients with this condition may be at some increased risk of subsequent breast cancer, and close clinical and radiological surveillance of any woman with this condition is indicated. Only rarely does an invasive cancer cause nipple discharge in the absence of a clinical mass. Scant data exist on the frequency with which in situ cancers that cause nipple discharge are visible on mammography, but it is recognized that a significant percentage of malignant lesions causing nipple discharge are not visible on mammography. A diagnosis of invasive or noninvasive cancer is often established only by microdochectomy, but this operation is rarely, if ever, therapeutic. There were no local recurrences in those patients who had radiotherapy postoperatively. Concerns about the safety of nipple-preserving breast-conserving surgery in patients with nipple discharge were raised by the retrospective review of Obedian and Haffty (21). The problem with such retrospective series is that margins were not adequately documented in most patients. It cannot, therefore, be determined whether the high local recurrence rates reported by Obedian were attributable to residual tumor underneath the nipple. Bloody Nipple Discharge in Pregnancy Nipple discharge with blood present, either visibly or cytologically, during pregnancy or lactation is common. In 20% of women who experience nipple discharge during pregnancy, blood is evident clinically. The likely cause is hypervascularity of developing breast tissue; it is benign, usually settles quickly, and requires no specific treatment. Galactorrhea is characterized by copious bilateral milky discharge not associated with pregnancy or breast-feeding. A careful drug history should be taken because a number of drugs, particularly psychotropic agents, cause hyperprolactinemia. Blood should be taken in patients with galactorrhea to measure prolactin, and if prolactin levels are significantly elevated (1,000 mU/L) in the absence of any drug cause, then a search for a pituitary tumor should be instituted. Galactorrhea disappears after appropriate drug therapy or surgical removal of any pituitary adenoma. Bromocriptine is an alternative, but it is no longer used because it produces significant side effects in up to one-third of patients including, very rarely, strokes (24). For patients with troublesome galactorrhea who are intolerant of medication, bilateral total duct ligation is effective. Periductal Mastitis and Duct Ectasia A variety of terms have been applied to the conditions now known as periductal mastitis and duct ectasia. Haagensen first introduced the term duct ectasia and considered the condition to be an age-related phenomenon; he believed that breast ducts dilated with age and that stagnant secretions in these dilated ducts leaked into surrounding tissues to cause periductal mastitis. This description of events ignores the findings that periductal inflammation predominates in young women, whereas duct dilatation increases in frequency with advancing age; the sequence of events described by Haagensen is therefore incorrect. If periductal mastitis and duct ectasia are related, then patients with duct ectasia would be expected to have a history of episodes of periductal mastitis. Substances in cigarette smoke may either directly or indirectly damage the wall of subareolar ducts. Accumulation of toxic metabolites-such as lipid peroxidase, epoxides, nicotine, and cotinine-in the breast ducts has been demonstrated to occur in smokers within 15 minutes. Smoking has also been shown to inhibit growth of gram-positive bacteria in vivo and in vitro, leading to an overgrowth of gram-negative bacteria. This may affect the normal bacterial flora and allow overgrowth of pathogenic aerobic and anaerobic gram-negative bacteria, and would explain the presence of these organisms in the lesions of periductal mastitis. Microvascular changes have also been recorded in smokers and may result in local ischemia (27). The combination of damage caused by toxins, microvascular damage by lipid peroxidases, and altered bacterial flora appears to explain why smokers develop periductal mastitis. Etiologic data thus suggest that periductal mastitis and duct ectasia are separate conditions with different causes. Duct ectasia appears to be an involutionary phenomenon, whereas periductal mastitis is a disease in which smoking and bacteria are important causal factors. Other Causes of "Nipple" Discharge Clinical Syndromes Periductal mastitis is characterized clinically by episodes of periareolar inflammation with or without an associated mass, a periareolar abscess, or a mammary duct fistula. Nipple retraction can be seen early at the site of the affected duct and is often subtle. The clinical features of duct ectasia include nipple retraction at the site of the shortened duct or ducts and creamy or cheesy, viscous, toothpaste-like nipple discharge. Patients with green discharge from multiple ducts are often diagnosed as having duct ectasia, but most of these have leaking physiologic breast secretion. In one large series, periductal mastitis principally affected women between the ages of 18 and 48 years, whereas most patients who presented with duct ectasia were aged between 42 and 85 years. The frequency of the condition increases with age and in one postmortem study, 48% of women aged 60 years or older had pathologic evidence of duct ectasia. Although early studies suggested that the lesions of both periductal mastitis and duct ectasia are sterile, when appropriate transport media are used, bacteria can be isolated from 83% of periareolar inflammatory masses and 100% of nonlactational abscesses and mammary duct fistulae. In contrast, in a study of duct ectasia lesions bacteria were identified in only 1 of 11 patients, indicating that these lesions are usually sterile. An association between smoking and periductal mastitis was first reported in 1988 (26). A subsequent study showed that heavy smokers are more likely to have recurrent infections including abscesses and mammary duct fistulae than light smokers or nonsmokers. It usually presents with a bloodstained discharge or change in contour or color of the nipple. Clinically, there is a nondiscrete mass in the substance of the superficial layer of the nipple. Eczema or dermatitis can sometimes involve the nipple and is usually caused by irritation from chemicals on clothes or in cosmetics. Treatment for eczema is removal of any aggravating factor, such as perfumed soap or detergents, by the use of hypoallergenic washing materials for clothes and skin, and prescription of topical corticosteroids. Short courses of potent corticosteroids are often more effective at resolving nipple eczema than longer courses of dilute preparations. Long-standing nipple inversion with maceration is rare but is seen in some elderly people. Repeated nipple trauma caused by friction from rubbing of clothes on the nipple during jogging and cycling is sometimes sufficiently severe to cause nipple excoriation and bleeding. The acquired causes, in order of frequency, are duct ectasia, periductal mastitis, carcinoma, and tuberculosis. Management depends on the presence or absence of a clinical or mammographic abnormality. Central, symmetric, transverse slit-like retraction is characteristic of benign disease; nipple inversion occurring in association with either breast cancer or inflammatory breast disease is more likely to involve the whole of the nipple and, in a breast cancer, to be associated with distortion of the areola, which may be evident only when the breast is examined in different positions. Benign nipple retraction requires no specific treatment, but can be corrected surgically if the patient requests it and the surgeon considers the operation appropriate. Division or excision of the underlying breast ducts (total duct division or excision) may be required to evert the nipple; patients should be warned that they will not be able to breast-feed after this procedure and may lose some nipple sensation. Papillomas visible on ultrasonography can be removed by needle localization or percutaneous vacuum-assisted biopsy. Total Duct Excision or Division Total duct excision can be a diagnostic procedure in older patients with nipple discharge and is indicated for multiple troublesome duct discharge or nipple eversion, and as treatment for periductal mastitis and its associated complications. Because the lesions of periductal mastitis usually contain organisms (Table 5-1), patients having operations for this condition should receive appropriate perioperative antibiotic treatment. Some surgeons prefer total duct excision in older women with single-duct discharge who no longer wish to breast-feed. The reasoning is that is it is more likely than single-duct excision to obtain a specific diagnosis (15,16) and if there is a condition, such as duct ectasia, that affects all the ducts underneath the nipple, then any further discharge from the other affected ducts will be prevented. Curved tissue forceps are passed around the ducts, and these are delivered into the wound. The ducts are secured and then divided from the undersurface of the nipple and, if a total duct excision is being performed, a 2- to 5-cm portion of ducts is excised depending on whether the operation is diagnostic or therapeutic. For patients having cosmetic nipple eversion, the procedure can be performed through a small incision either at the areolar margin or at the base of the nipple and the ducts are divided sufficiently to ensure that the nipple everts. If the operation is being performed for periductal mastitis, the back of the nipple must be cleared of all ducts up to the nipple skin because recurrence can occur when residual diseased ductal tissue is left. In periductal mastitis only 2 to 3 cm of all the ducts need to be removed as the disease affects only the subareolar ducts. The discharging duct is cannulated either with a probe or a blunt-ended needle through which methylene blue can be injected. These various procedures allow the involved duct to be identified under the surface of the nipple. The discharging duct is dissected distally into the breast; a portion of duct over a distance of approximately 5 cm is removed because almost all significant disease affects the proximal 5 cm (9,28). If the remaining duct within the breast appears abnormal and dilated, then the distal duct can be excised or opened and any pathologic lesion in the remaining duct can be visualized and removed. This is an important maneuver because ductoscopy indicates that many significant lesions affect ducts some distance from the nipple. When performing a duct excision directed by ductoscopy, having visualized the abnormality in the duct, transmitted light immediately proximal or at the site of the lesion is used to direct the surgical excision. Once excision has been performed, the nipple should be squeezed gently to ensure that the discharging duct has been removed.
