Proliferation of ducts in hyalinized fibrous tissue with periductal edema Reproductive Systems Answers 354. Because of a malformation the urethral opening may be located either on the ventral (inferior) surface of the penis (hypospadias) or the dorsal (superior) surface (epispadias). These abnormal locations may produce obstruction, urinary tract infection, or problems with infertility. Hypospadias, which is more common, results from failure of the urethral folds to close, while epispadias results from faulty positioning of the genital tubercle. In contrast, abnormal development of the prepuce (foreskin) may result in the inability for it to retract over the glans penis, this condition being called phimosis. Abnormal fusion of the paramesonephric ducts can produce uterine abnormalities, such as a double uterus or a bicornuate uterus. This may be due to inflamma to ry scarring or abnormal development of the pre puce. If a phimotic prepuce is forcibly retracted over the glans penis, a con dition called paraphimosis may develop. This condition is extremely painful and may cause obstruction of the urinary tract or blood flow, which may lead to necrosis of the penis. Genital malformations may cause an abnormal location of the urethral opening, either on the ventral surface of the penis (hypospadias) or the dorsal surface (epispadias). Hypospadias is the result of failure of the urethral folds to close, while epispadias is the result of faulty positioning of the genital tubercle. These changes are found in both condyloma acuminatum and verrucous carcinoma, but condyloma is a benign papillary lesion that does not grow in to the under lying tissue, while verrucous carcinoma, also known as giant condyloma or Buschke-Lowenstein tumor, invades the underlying tissue along a broad front. This type of invasion is in contrast to squamous cell carcinomas, which invade tissue as finger-like projections of atypical squamous epithe lial cells. It is present in up to 1% of males after puberty and is unilat eral in the majority of cases. The interstitial cells are usually prominent and occasional focal proliferations of Ser to li cells may be seen. The incidence of malignancy is increased 7 to 11-fold, and this risk is greater for abdominal than for inguinal locations. There is a smaller but definite risk of malignancy in the contralateral, correctly placed testis. Transillumination is helpful in differenti ating between cysts (which transilluminate) and tumors (which do not), but an inguinal-scrotal imaging ultrasound is used to confirm the diagnosis. Recall that the processus vaginalis is an outpouching of the peri to neum that enters in to the scrotum. When the testis reaches the scrotum, the proximal portion of the processus vaginalis obliterates, but the distal portion persists and does not fuse. Examples of cysts that involve this tunica vaginalis include hydroceles, hema to celes, chy loceles, and sperma to celes. Hydroceles contain clear fluid and result from developmental abnormalities or inflamma to ry processes. Hema to celes result from hemorrhage in to a hydrocele, while chyloceles result from the accumulation of lymph fluid within the tunica as a result of elephantiasis. In contrast to transillumination and imaging ultrasound, Doppler flow studies are used to assess perfusion to the testis, while testicular scintigra phy is a type of nuclear scan. Both of these tests are quite useful if testicu lar to rsion is suspected clinically. Seminomas typically spread via lymphatics after having remained localized for a long time. Embry onal carcinoma, choriocarcinoma, and mixed tumors with an element of chori ocarcinoma tend to metastasize early via the blood. Seminomas are characterized his to logically by large cells with distinct cell membranes and clear cy to plasm. It is characterized by being found in older individuals and by the fact that it does not metastasize. His to logically, a sperma to cytic seminoma is characterized by maturation of the tumor cells, some of which his to logically resemble secondary sperma to cytes. In contrast to the his to logic appearance of seminomas and sperma to cytic seminomas, choriocarcinomas have a mixture of malignant cy to trophoblasts and syncy tiotrophoblasts, malignant tera to mas have tissue derived from all three germ levels with scattered immature neural elements, Leydig cells tumors have large tumor cells with abundant eosinophilic, granular cy to plasm, and rare intracy to plasmic rhomboid crystals, and finally, embryonal carcinomas have sheets of undifferentiated tumor cells. It may be secreted by either yolk sac tumors (endodermal sinus tumors) or embryonal carcino mas. Markedly elevated serum levels are most often associated with choriocarci nomas, which are characterized his to logically by a mixture of malignant cy to trophoblasts and syncytiotrophoblasts. But there are many areas of overlap between tumors, and many tumors are composed of multiple types of germ cell cancers. Patients with acute prostatitis present with the sudden onset of fever, chills, and dysuria. Acute prostatitis is usu ally caused by bacteria that cause urinary tract infections and urethritis, most commonly gram-negative infections, especially with Escherichia coli. Chronic prostatitis presents clinically as low back pain, dysuria, and suprapubic discomfort. Instead, chronic abacterial prostatitis is associated with infections with either Chlamydia trachomatis or Ureaplasma urealyticum. Chlamydia trachoma this should be suspected in patients with chronic prostatitis with negative cul tures of urine and prostatic secretions. The most common cause of granuloma to us prostatitis in the United States is Bacillus Calmette-Guerin, which is used for the treatment of superficial cancer of the urinary bladder. His to log ically, the hyperplastic nodules are composed of a variable mixture of hyperplastic glands and hyperplastic stromal cells. Urinary obstruction results because the inner, periurethral por tions of the prostate (the middle and lateral lobes) are affected most com monly. His to logically, these malignant glands are composed of a single layer of cuboidal epithelial cells, because the outer basal layer of epithelial cells, seen in normal and hyperplastic glands, is not present. Most adenocarcinomas of the prostate originate in the peripheral zone, while hyperplastic nodules originate in the transition zone. This ana to mic differentiation is the result of the physi ologic fact that the transition zone is particularly estrogen-sensitive, while the peripheral zone is particularly androgen-sensitive. The mesonephric ducts in males, if stimulated by tes to sterone secreted by the Reproductive Systems Answers 451 Leydig cells, develop in to the vas deferens, epididymis, and seminal vesi cles. In contrast, because normal females do not secrete tes to sterone, the Wolffian ducts regress and form vestigial structures. They may, however, form mesonephric cysts in the cervix or vulva, or they may form Gartner duct cysts in the vagina. The cranial group of mesonephric tubules (the epoophoron) remains as vestigial structures in the broad ligament above the ovary, while the caudal group of mesonephric tubules (the paroophoron) forms vestigial structures in the broad ligament beside the ovary. The para mesonephric (Mullerian) ducts in the female form the fallopian tubes, the uterus, the uppermost vaginal wall, and the hydatid of Morgagni.

Surgery should be conservative, because the primary objective is to exclude cancer. Simple mastec to my or extensive removal of breast tissue is not indicated for fibrocystic disease. Most patients do not require treatment for fibrocystic changes, just reassurance that fibrocystic change is a transient phenomenon of aging that is associated with hormonal effects on the breast glandular tissue that eventually subsides. The common coincidence of fibrocystic disease and malignancy in the same breast reflects the fact that both processes are common events. In an evaluation of the relationship between fibrocystic change and breast cancer in 10,366 women who underwent biopsy between 1950 and 1968 and were followed for a median of 17 years, approximately 70% of the biopsies showed nonproliferative breast disease, whereas 30% showed proliferative breast disease (95). Women with nonproliferative disease had no increased risk of breast cancer, whereas women with proliferative breast disease and no atypical hyperplasia had a twofold higher risk of breast cancer. Patients whose biopsy results showed atypical ductal or lobular hyperplasia had an approximately fivefold higher risk than women with nonproliferative disease to develop invasive breast cancer in either breast. Patients with carcinoma in situ have an eight to tenfold risk of developing breast cancer. A family his to ry of breast cancer added little risk for women with nonproliferative disease, but family his to ry plus atypia increased breast cancer risk 11-fold. Women with these risk fac to rs (family his to ry of breast cancer and proliferative breast disease) should be followed carefully with physical examination and mammography. For such women, age-specific probability of developing invasive breast carcinoma in the next 10 years is 1 in 2,000 (age 20), 1 in 256 (age 30), 1 in 67 (age 40), 1 in 39 (age 50), and 1 in 29 (age 60) (93). The relative risk for developing breast cancer depends on the type of proliferative lesion diagnosed. Management of Fibrocystic Change Fibrocystic change is a normal evolutionary change in breast development and involution and does not require a specific treatment other than a good clinical breast examination and age-appropriate mammographic screening or imaging studies directed to signs and symp to ms. A number of nutritional and dietary supplements were investigated to relieve symp to ms. Results of some studies suggest that eliminating caffeine from the diet is associated with improvement of symp to ms (100,101). Many patients are aware of these studies and report relief of symp to ms after discontinuing intake of coffee, tea, and chocolate. A recent review of nutritional interventions for fibrocystic breast conditions that evaluated evening primrose oil, vitamin E, or pyridoxine suggested that there are insufficient data to draw clear conclusions about their effectiveness (107). Exacerbations of pain, tenderness, and cyst formation may occur at any time until menopause, when symp to ms usually subside unless patients are taking estrogen. A patient with fibrocystic changes should be advised to examine her own breasts each month just after menstruation and to inform her physician if a mass appears. Mastalgia Mastalgia is a recognized organic condition that is studied less thoroughly than other breast problems (108,109). A study evaluating expression of interleukin-6 and tumor necrosis fac to r-fi in painful and nonpainful breast tissue showed lower levels of these cy to kines in painful breast tissue during the luteal phase; however, these levels did not reach statistical significance (110). Elevated estrogen, low progesterone, or an imbalance in the ratio of estrogen and progesterone were suggested as a possible cause for the symp to ms (111). Natural His to ry of Mastalgia Approximately 70% to 80% of women experience severe breast pain at some time in their lives (112,113). In 15% of the patients, the mastalgia is so severe that it alters lifestyle and requires repeated investigations and treatment (112). Mastalgia interferes with sexual (48%), physical (37%), social (12%), and work or school activities (8%) (115). Types of Mastalgia Breast pain is a distressing constellation of symp to ms that is classified as cyclic, noncyclic, or extramammary (116). Cyclical mastalgia is more prevalent in women in their third and fourth decades of life and accounts for two-thirds of all breast pain symp to ms (119). Noncyclic mastalgia is independent of menstrual cycles and is described as achy, burning soreness. It may be intermittent or constant, is usually unilateral, occurs in the fourth and fifth decades, and is more difficult to treat than cyclic mastalgia (116). Extramammary pain is perceived to be located in the breast but is related to an extramammary site. Chest wall muscular pain, costal cartilage symp to ms, herpes zoster, radiculopathies, and rib fractures are among some of the more common causes of extramammary pain. Cos to chondritis (Tietze syndrome) is a manifestation of chest wall pain that is frequently interpreted as breast pain. Management of Mastalgia Breast pain is an unlikely symp to m of malignancy, and when malignancy is excluded by a clinical breast examination and age-appropriate breast imaging for focal breast pain, the most important treatment is reassurance. Treatments include medications, such as anesthetics, diuretics, bromocriptine, and tamoxifen; vitamins and supplements, such as evening primrose oil; mechanical support with a well fitting bra; local excision; and decreased fat intake and reduction in methylxanthines from caffeine, tea, and chocolate (108,116). Maintenance of a pain score diary is important to understand the relationship of pain to fac to rs such as the menstrual cycle, activities of daily living, and stress. External support may be effective for breast pain associated with generalized fibrocystic changes and is best treated by avoiding trauma and by wearing (night and day) a brassiere that gives good support and protection (120). One study evaluated resolution of symp to ms in 200 women randomized either to a regimen of danazol (200 mg per day) or to mechanical support with a sports brassiere worn for regular activities for 12 weeks. The group using mechanical support had 85% relief of symp to ms compared with 58% improvement in the danazol group. The danazol group experienced drug-related side effects in 42%, which led to discontinuance of the medication in 15%. The breast has minimal structural support and is at significant risk for motion-related displacement resulting in mastalgia. The use of external support to minimize breast motion appears to be effective in reducing breast pain. The application of heat packs or cold packs and light breast massage may reduce symp to ms in some individuals (116). These drugs are associated with significant side effects that limit their general use (116). Withdrawal of birth control pills or hormone therapy may be all that is required to alleviate symp to ms (116). Danazol is a synthetic androgen that suppresses release of pituitary gonadotropin, prevents luteinizing hormone surge, and inhibits ovarian steroid formation. It can be initiated at doses of 100 to 200 mg twice daily orally for patients with severe pain and then tapered to a lower dose of 100 mg per day (122). A survey of surgeons in Great Britain revealed that 75% prescribed danazol as first-line therapy (108). A study conducted to evaluate the response to administration of danazol revealed a 79% amelioration of symp to ms (125). This approach reduced the premenstrual mastalgia and resulted in virtually no side effects. Further studies may be warranted to see whether medroxyprogesterone acetate suppresses cyclic mastalgia in reproductive-age women. A randomized, double-blind study with supraphysiologic levels of iodine in women with documented cyclic mastalgia demonstrated dose-dependent reduction in physician-assessed and self-reported pain at 3 and 6 months of treatment (130). Side effects of goserelin include vaginal dryness, hot flushes, decreased libido, oily skin and hair, and decreased breast size. A recent clinical trial randomized 147 women in to goserelin versus placebo groups. The mean breast pain score decreased by 67% in the goserelin arm and 35% in the placebo arm. The authors concluded that goserelin is an effective treatment for mastalgia with significant side effects and should be kept as second-line therapy. Hormonal blockade of the estrogen recep to r is another approach to minimizing the effects of circulating estrogen on breast pain. There was a significant reduction in cyclic and noncyclic pain in all groups, but the magnitude of change was greater in the treatment arms and similar for cyclic and noncyclic pain. Nonhormonal therapies such as dietary restrictions, vitamins and supplements, and restriction of methylxantines were investigated as possible treatments for mastalgia because they are less likely to be associated with adverse drug-related side effects (116). Because mastalgia is one of the symp to ms associated with fibrocystic disease, the treatments described for fibrocystic disease are relevant to mastalgia. Ninety percent of patients taking in 15% dietary fat experienced resolution of pain symp to ms after 6 months compared with only 22% of those on a diet containing 36% fat (p =. It was used as first-line therapy, reserving danazol and bromocriptine for treatment of more severe symp to ms (112). Those who responded had a lower level of essential fatty acids at the time of initiation when compared with poor responders, suggesting that evening primrose oil increases essential fatty acids and that this increase may be associated with the improvement in symp to ms in the responders. Two other trials failed to demonstrate efficacy of evening primrose oil capsules over placebo (139,140). In a Dutch trial, 124 women with cyclic or noncyclic pain lasting on average 7 or more days (minimum 5 days) were randomized to receive the following regimens: (i) fish oil and control oil, (ii) evening primrose oil and control oil, (iii) fish and evening primrose oil, or (iv) both control oils for 6 months (139). There was a statistically significant reduction in the number of days per month with pain but not in the pain score in the entire study population. There was a greater reduction in cyclic than noncyclic pain symp to ms, and this finding was true for both the test oils and for the control oils. The authors concluded that neither fish oil nor evening primrose oil had a better effect than the less expensive wheat germ and corn oils. A second large double-blind randomized prospective trial was conducted in 555 women with cyclic mastalgia of moderate to severe degree present for at least 7 days of a menstrual cycle (140). There was continued improvement of symp to ms in all groups with a reduction in mastalgia by 50% over the next 12 months. The results of this study were not consistent with those from previous smaller studies. The randomized trials, however, bring in to serious question the efficacy of these options. Fibroepithelial Lesions Fibroadenoma Fibroadenomas are the most common benign tumors of the breast. They usually occur in young women (age 20 to 35 years) and may occur in teenagers (142). They rarely occur after menopause, although occasionally they are found, often calcified, in postmenopausal women. For this reason, it is postulated that fibroadenomas are responsive to estrogen stimulation. A study reports the de novo occurrence of fibroadenoma in 51 women older than age 35 years who had no evidence of a palpable or mammographic visualized lesion in well documented prior visits (143). Most masses are 2 to 3 cm in diameter when detected, but they can become extremely large. They do not elicit an inflamma to ry reaction, are freely mobile, and cause no dimpling of the skin or nipple retraction. On mammographic and ultrasonographic imaging, the typical features are of a well-defined, smooth, solid mass with clearly defined margins and dimensions that are longer than wide and craniocaudad dimensions that are less than the length. The natural his to ry of fibroadenoma can be regression, growth, or no change in size. Most fibroadenomas are static or cease growth at approximately 2 to 3 cm, about 15% of tumors regress spontaneously, and only 5% to 10% progress (145). Because transformation of a fibroadenoma in to cancer is rare and regression is frequent, current management recommendations are conservative unless there is evidence of growth (141). Complete excision of a fibroadenoma with local anesthesia can be performed to treat the lesion and confirm the absence of malignancy. Less invasive local treatment of a fibroadenoma is advocated by some and can be performed with either ultrasonographically guided percutaneous vacuum-assisted biopsy devices or percutaneous cryoablation (146,147). A young woman with a clinical fibroadenoma can undergo needle cy to logy and observation of the mass (148). Acceptance of observation varies, and many women choose to have the fibroadenoma excised (149). On gross examination of an excised mass, the fibroadenoma appears encapsulated and sharply delineated from the surrounding breast parenchyma. Microscopically, there is proliferation of both the epithelial and stromal component. In longstanding lesions and in postmenopausal patients, calcifications may be observed within the stroma. Excision of all lesions through separate incisions could leave significant scarring and deformity. Excision of these mobile lesions through a single periareolar incision was suggested, but this approach can lead to significant ductal disruption (153). Phyllodes Tumor Phyllodes tumors are rare fibroepithelial tumors that display a spectrum of clinical and pathologic behaviors that are benign, borderline, and malignant (154,155). The distribution of phyllodes tumors demonstrates that most tumors are benign (70%) compared with malignant (23%) and borderline lesions (7%) (156). This distribution is similar to a larger, older study that reported an incidence of 64% benign, 21% malignant, and 14% borderline phyllodes tumors (157). The incidence in some studies should be viewed with caution because of variation in his to logic interpretation (156). These lesions are rarely bilateral and usually appear as isolated masses that are difficult to distinguish clinically from a fibroadenoma. Patients often relate a long his to ry of a previously stable nodule that suddenly increases in size. Size is not a dependable diagnostic criterion, although phyllodes tumors tend to be larger than fibroadenomas, probably because of their rapid growth. There are no good clinical criteria by which to distinguish a phyllodes tumor from a fibroadenoma. Whereas observation of a fibroadenoma is acceptable, excision of a phyllodes tumor is necessary for local control and for determination of benign or malignant features. Ultrasonography evaluation has limitations even when color and pulse Doppler ultrasonography are used in conjunction with it (163). It may be easier to distinguish benign phyllodes from malignant phyllodes tumors than benign phyllodes tumors from fibroadenomas (170). His to logic features that stratify lesions include number of mi to ses per high power field, stromal cellularity, pushing or infiltrating tumor margin, cellular atypia, tumor necrosis, and stromal overgrowth (171). If a lesion cannot be clearly characterized as a fibroadenoma, excision may be necessary. Fac to rs that are considered in recommending excision include older age, new mass in a well-screened individual, rapid growth, size greater than 2. If observation is elected, repeat clinical examination and imaging in a short interval is essential to evaluate change in size. Massive tumors, or large tumors in relatively small breasts, may require mastec to my; otherwise, mastec to my should be avoided, and axillary lymph node dissection is not indicated. Often, however, a patient will undergo excisional biopsy of a mass believed to be fibroadenoma, and final his to logic examination reveals a phyllodes tumor. Reexcision with normal breast margins is recommended for borderline and malignant phyllodes tumors (159). An expectant approach is an option for unanticipated diagnosis of benign phyllodes tumors (157). The prognosis of benign and malignant phyllodes tumors is variable (154,155,157,162,172).

Will they have the physical or the emotional energy, the time, the desire or the fnancial resources to have more childrenfi They may need help thinking through their choices and the implications of those choices. They need information that they can understand to make the best choice given the present state of knowledge. As described in the Damocles Syndrome,1 parents are constantly waiting for the next bad thing to happen. Helping families adjust to living each day to the fullest and to focus on activities apart from the illness are crucial components in day- to day coping. The moments that are not driven by medi cal crises are times for families to learn and stay abreast of salient treatment options and to prepare themselves for the future. Being prepared to take appropriate action, feeling informed, and feeling supported, all help family members to move forward with the necessary tasks dur ing these periods. With some of the very diffcult choices that parents will have to make for and with their children, there is no turning back. Therefore, each major decision requires that families and older patients know all they can prior to making the decision, with an opportunity to integrate the information and refect upon and accept the choices they have made. In certain cases, families will be mak ing decisions about experimental procedures and pro to cols which have been utilized with very few patients. Families experience a vulnerability and a unique anxi ety when they know they are traveling on a road that few have traveled before. One parent may need to learn everything there is to learn to plan strategically for the future, whereas the other may choose to stay focused in the moment. Differences in coping styles as they relate to gender and culture should be recognized so each can be supported for his or her strengths, insight, and ability during the course of the illness. On the other hand, some couples have felt that the strain and the magnitude of the issues they face have made them stronger to gether. Depression and anxiety are two uncomfortable emo tions characteristics that may accompany this disease. Many parents feel anxious or depressed from the onset, unsure of what to anticipate. The ability to contain the anxiety or depression, to make decisions, to enjoy life, and to continue to function are skills to be mastered. Talking to other parents, understanding their decision-making processes, and getting support help parents to maintain the balance they need. These support groups offer parents the oppor tunity to be parents: to be able to compare their child to other children, to seek companionship of another parent in a similar situation, to brains to rm, to share informa tion, and to join the fght against Fanconi anemia and become empowered in the face of the illness. Families may be viewed incorrectly as aggressive when they advocate in the interests of their children. There may be moments when families and individual physi cians do not agree on treatment options and alterna tives. The involved professionals must work to make the best decisions with, and not for, families. This strategy will Chapter 16: Psychosocial Issues 295 help minimize potential later regrets for families and professional staff. Helping navigate the course of the illness, and thinking through decisions can help those facing such rare illnesses feel much less isolated. Parents describe having a greater appreciation for the things they do with their children, learning how to experience each day to its fullest. This process can be fnancially, emotionally, and physically draining and in some cases, all-consuming. Families can beneft from talk ing with others who have been in this situation to help mitigate the intense emotions that can occur during this time. If parents create an environment that allows for questions, discussions, and an expression of feelings, children will feel free to ask their parents about their illness and treatment options and become active participants in the disease management. Children often know much more about what is happen ing than adults might believe. In addition to what they have been to ld, they pick up information from ambient conversation, have independent interactions with pro fessionals, and surmise things from the emotional cli mate around them. They will ask questions when they want to know, and will often shy away from questions to which they do not want the answers. Children are good regula to rs of their own knowledge base, providing cues to the adults around them at all junctures. Children need to be able to confde in their parents and others when they feel limited physically or socially by Fanconi anemia. At each stage of development, children need age-appropriate explanations of their diagnosis and treatment. Information offered regularly to children will enhance their ability to understand their disease and establish trusting relation ships. As they get older and medical problems emerge, groundwork set in earlier years will encourage patients to rely on health care providers. Others may have no known problems but, because of illness-related absence, may need extra assistance. School-age children develop increasingly strong rela tionships with their peers as they begin to differentiate themselves from their families. Each child and family must fnd a bal ance in social and family relationships, which allows for a blend of independence and dependence, nurturing and differentiation. They may, therefore, come to understand and deal with issues with which adults may not feel comfortable. Thus, they may seem more mature than their chrono logical ages and often are more sophisticated than their peers in matters of illness and death. They may also appreciate life, and the meaning of life, more than the adults they encounter. For adolescents, challenging the rules is age-appropriate and functional at times for emotional growth. It allows them to assert themselves as individuals and to begin to learn to take responsibility for their actions. Young adults report s to pping their medications, sun bathing, drinking alco hol, smoking, etc. Compliance with medication regi mens may be of concern and should be given particular attention at this stage, as should the risk-taking behav iors associated with greater chances of malignancy. As children get older, they need to be involved in assenting, consenting, and participating in actual deci sions about their medical care. As their children become more active decision-makers, parents may feel some Chapter 16: Psychosocial Issues 299 relief that they are now making decisions with, rather than for, their children. Yet as children approach young adulthood, parents have expressed anxiety about how their children will learn to make complicated, sophisti cated decisions for themselves. For some young adults, the decisions will continue to be made in partnership with their parents. This time of growth for the person with Fan coni anemia also becomes a time of growth for parents. Children of all ages need to be allowed to con tinue to grow, regardless of the status of their medical conditions. Achievements, great or small, cultivate growth and satisfaction for both children and parents. Children need to be prepared to be successful and moti vated in life, and not exclusively focused on Fanconi anemia. Siblings Siblings present their own unique concerns, some vis ible and some invisible. They may feel guilty that the disorder happened to their sibling and not to them or may feel that they are less important because they are not getting as much attention. Siblings care about and 300 Fanconi Anemia: Guidelines for Diagnosis and Management worry about each other a great deal. For many, their universe is defned by their role as either an older or younger brother or sister. Siblings of children with life-threatening or fatal illnesses often have as much of an emotional response to the illness as the affected children. Open communication, the opportunity for expression, and the ability to process the experience help siblings to fnd their place in the world. Siblings need their own time with parents, medical knowledge appro priate to their age, and to truly be and feel that they are an integral part of the family. These relationships have a very powerful presence that may not always be visible in a family. It is important that affected and non affected siblings have the opportunity to talk with each other and with their parents. These can be among the strongest relationships in life and need to be cultivated and nurtured during this journey. Young adults who face the most severe manifestations of the illness may, of necessity, Chapter 16: Psychosocial Issues 301 remain more physically and emotionally dependent on family members. On the other hand, their family con nections may reach deeper levels than those of their healthy peers. It is important to help such individuals gain their indepen dence while helping them understand that they can still rely on their families for support and assistance. Family members need to work to gether to understand the best decision-making practices in their families. Fanconi anemia affects the whole family, not just when a child is initially diagnosed, but through out the course of the illness. Some of the magnitude of the diagnosis is not apparent to the child until he or she reaches adolescence and young adult years. Relationships, 302 Fanconi Anemia: Guidelines for Diagnosis and Management peer pressure, experimentation with drugs and alcohol, and sexual relationships all pose emotional and physi cal challenges. The issues of whom to tell, when to tell, and what to tell seem to be related to whom to trust and an ongoing evaluation of who needs to know what and why. These issues can frame early stages of relationships with roommates and romantic partners. As relationships fourish, there is a natural inclination to think to wards the future. All of this may infuence how they make choices of friends, relationships, careers, marriage, and parenthood. Partners also need an outlet for information, expression, and help at times when their partner is not doing well or has to make major life decisions. Negotiating their roles as partners and with parents who have nurtured their children for decades can be quite challenging. Increasing numbers of children are becoming young adults and adults with Fanconi anemia. In the same way that the needs of the children and then teens became a priority as treatment evolved, now the needs of these adults, physically and emotion ally, become the priority. The medical course of Fan coni anemia is evolving, allowing for the emotional and physical sequelae to be better unders to od. Emotional connections for this group can be found in young adults 304 Fanconi Anemia: Guidelines for Diagnosis and Management and adults with other rare illnesses who have survived to adulthood. The Death of a Child If a patient nears death, the patient and the family need emotional support, clear thinking, concrete assistance, and tremendous understanding. By this point, the fam ily has lived through many struggles with the illness and therefore may continue fghting longer than oth ers might expect. Fighting, trying the next thing, and looking to wards experimental options are the armor that families use to cope. Providing information and opportunities for discussion, helping families make decisions, supporting their choices, comforting, remembering, and remain ing available are signifcantly helpful to families at this stage. Rarely do bereaved parents feel that their loss is unders to od and therefore their ability to accept support, except from people in similar situations, may be limited. Chapter 16: Psychosocial Issues 305 Relationships with families should not end abruptly during the bereavement period, because it is a most diffcult phase for them. Assisting families to under stand many of the more intense feelings (anger, regret, loneliness, depression) as part of the natural process at this time is helpful. The complication of having a genetic illness, an illness that a family will have to deal with for generations to come, adds to the complexity of coping after a child dies. Enable patients, as they mature, to become responsible and proactive with regard to their medical care (recom mended by a focus group of parents). The increasing prevalence of complicated mourn ing: the onslaught is just the beginning. Or grieving can begin later, when baffing physical symp to ms fnally lead to the diagnosis of Fanconi anemia. The grief one experiences often proceeds in predictable stages, as one struggles to cope with this devastating reality. Since this illness often progresses slowly and patients sometimes live for years or decades after diagnosis, the family suf fers from chronic grief. With every acute crisis of this illness, loved ones experience again the most painful phases of the grieving process. Experts who study stages of grieving often refer to four phases, which usually proceed in order, but can co-exist in the same time frame. It is also possible to survive one phase only to fnd oneself experiencing feelings or behaviors characteristic of an earlier phase. This phase can last from hours to months and is often intermingled with the second stage of grief. Emotions commonly experienced are crip pling sadness, anger, guilt, anxiety, despair, terror, and feeling out of control. When par ents have unknowingly passed lethal genes on to their children, feelings of guilt can be quite intense, however irrational. Disorganization the third phase of the grieving process is often referred to as a period of disorganization. The emo tions of the second phase continue, but the waves of sadness, anger, anxiety, and other disabling emotions are less intense. Most parents feel that part of their role is to protect their children from danger ous, unhappy experiences.

Chemical pneumonitis leads to release of cy to kines and leukotrienes that can increase pulmonary vasoconstriction. They also cause loss of surfactant function and decreased aeration of lungs and induce pulmonary edema by increasing vascular permeability. These changes consist of abnormal thickening of media and adventitia of pulmonary arteries and hypoxemia in the absence of recognizable parenchymal lung disease. Active precordium and sys to lic murmur of tricuspid insufficiency may be appreciated on cardiac exam. Although these criteria are still useful, certain caveats have to be considered to avoid errors in diagnosis. However, 2-site sampling for arterial blood is invasive and is not recommended for diagnosis. Moni to ring pre and post-ductal saturations is useful in gauging the response to pulmonary vasodila to r therapy. It is important to consider the lungs and heart as one unit, connected by pulmonary circulation. Ideal management will involve optimizing lung expansion and cardiac output while achieving pulmonary vasodilation and maintaining systemic pressure. It is important to avoid excessive levels of 457 oxygen or ventila to r pressures that can injure the lung. Hyperventilation can also have adverse effects on cerebral perfusion and induces hearing loss (blood supply to cochlea is part of cerebral circulation). Iloprost is the preferred agent since it can be given by intermittent nebulization, every 2 6 hours, depending on the duration of response. Milrinone works synergistically with inhaled prostacyclin in the same signaling axis. However, in this summary, Heart Rate and contractility are properties intrinsic to the heart itself and will be discussed. Mechanically, tachyarrhythmia can be classified as 1) reentry, 2) au to maticity, 3) triggered activity. Reentry occurs when there are differential rates of conduction and is 462 triggered by a premature beat. Au to maticity is a function of phase and depolarization ec to pic activity, action potential. Slow rates (bradycardia) can be from the atrium (sinus bradycardia) or the ventricle. Other causes include sinus disease (post-operative) hypercalcemia hpyermagnesemia. Treatment includes identifying the cacuse if one is present, epinephrine, atropine, or pacemaker, Ventricular bradycardia are functional blocks, stable patients are treated with epinephrine, unstable patients are paced. Fast rates (tachycardia) can stem from the atrium or the ventricle and may be hemodynamically problematic or not. Atrial Muttler (saw to oth pattern rate 150) should get a trial of procainamide, digoxin or ibutalide (0. In acute decompensated heart failure, there are no medications that are associated with increased survival. Theoretically, the end point of therapy is to achieve a great stroke volume for the same or lower preload. There is a current study on whether hypothermia is helpful in the pediatric patient. If epinephrine is given endotracheally, and is given in an acidic carrier, the indica to r may turn yell. Esophageal intubation can turn the litmus paper yellow for a few breaths if patient has carbonated beverages in the s to mach. This manifests as increased pulmonary blood flow and subsequent left ventricular overload since shunting occurs during sys to le. Lesions with similar pathophysiology include large ductus arteriosus and aor to pulmonary window. In the first 24 hours after surgery, the hypertension is due to a catecholamine surge and should be treated with sympatholytics such as labetalol. Dias to lic hypertension is more pronounced and spasm of the mesenteric arteries can be seen. Not all examples described will be true single ventricle lesions or refer to situations that result in true single ventricle ana to my after eventual repair. In such a scenario, an emergent atrial sep to s to my may be needed to establish an alternate source of Qp. The portion of to tal cardiac output directed Qp or Qs depends on the specific heart lesion (various degrees of obstruction) and the vascular resistance to flow in the pulmonary and systemic circuits. However, an estimate of Qp/Qs can be obtained with a pulse oximetry measurement and a few assumptions. If the patient has healthy lungs, then one can assume that the SpvO2 on room air approaches 100%. This allows for the ductus to provide blood flow to structures when the cardiovascular development creates a situation in which oxygenation or perfusion is impaired by congenital heart disease.

Sign-out of these infants off shift should include the acceptable parameters for the labora to ry work that will be done and who to contact (sub-specialty services) for changes in clinical status. Cold stress increases free fatty acids, which promote insulin secretion and can cause a reactive hypoglycemia. Bradycardia is almost always due to a suboptimal airway and failure to achieve adequate oxygenation. Occasionally difficult resuscitations require volume expansion in the delivery room. Introduction Ideally, there would be clinical evidence to use to determine which therapies should be administered to each of our patients. The most common and simplest forms of clinical research are case reports and case series or institutional experiences. These types of reports make up a large portion of the pediatric surgical literature as many of the diseases we treat are rare and not amenable to large prospective trials. Despite these limitations, these reports do provide at least an expert opinion or experience that can be used to draw some information about a disease or treatment and outcomes. The value of these types of studies is limited by selection bias but, often, they are the only types of data available. On a larger scale, outcomes studies or comparative effectiveness studies are being performed using databases. The databases for these studies can be institutional registries or data warehouses, multi-institutional registries such as the Extracorporeal Life Support Organization registry, state or national registries such as the National Trauma Data Bank, or large multi-institutional administrative databases such as the Pediatric Health Information System database or the Kids Inpatient database. In all database studies, groups of patients, treatments or outcomes of interest must be identified. It is critical that the identification and grouping of patients, treatments, and outcomes be described and validated as completely as possible. This is where the reliability and validity of these studies must be carefully evaluated. Each database will have varying levels of reliability with different rates of misclassification of variables and missing data. These limitations should be addressed and reported as completely as possible in each study. Prospective observational studies or prospective registries represent slightly higher levels of evidence. These studies identify variables to be collected and then prospective collecting the data. These are less biased because the data is defined and 485 collected prospectively for important variables, which can control for severity of illness. Although valuable, these studies are limited to establishing associations between variables or treatments and outcomes and cannot directly prove causality. In addition, for conditions that occur infrequently, recruitment of enough patients to adequately power a trial may not be feasible or may require a large multi-institutional effort,which would significantly increase the cost. Further available types of clinical research include systematic reviews and expert consensus guidelines. Systematic reviews are literature reviews about a particular treatment that will use techniques of meta-analysis to understand the effectiveness of a therapy across multiple studies. These reviews can provide measures of the consistency of the treatment effects of a therapy across studies, insights in to why different trials had varying results, and when appropriate, combine the results of the individual studies to provide an overall estimate of the treatment effect of a therapy [9, 10, 27]. Expert consensus guidelines are becoming more common in critical care with multiple guidelines being developed and sponsored by medical societies such as the Society of Critical Care Medicine, American Thoracic Society, American College of 487 Cardiology, and Infectious Disease Society of America. A consensus guideline is typically developed by a group of national and international experts who review and grade the available literature on a specific disease or therapy, and then make varying levels of treatment recommendations based on the strength of evidence to support the recommendation. An additional issue for pediatric critical care physicians is the availability of a large number of studies in adult patients with limited or no data available in children. Specific issues to consider prior to translating these studies to pediatric surgery are the specific endpoints measured and the length follow-up. Much adult critical care research will report in-hospital or 30 day primary outcomes such as death, pulmonary embolism, stroke, deep venous thrombosis, or myocardial infarction. Although these outcomes are important, they occur much less frequently in children and may not be the best primary outcome measures to determine the effectiveness of therapy in our patient population. In addition, our patient population is unique in that they are growing and developing, therefore measuring longer term outcomes, including assessments of the developmental and social impacts of our therapies, should be considered in pediatric critical care trials. As an example, hand hygiene has been documented to decrease hospita acquired infections and the Center for Disease Control has published evidenced-based guidelines for hand hygiene [33, 35]. Despite institutions providing the necessary products and supplies for compliance and high levels of staff member awareness of these guidelines, Larson et al demonstrated that hand hygiene compliance was only 56% across 40 member hospitals of the National Nosocomial Infection Surveillance System [33]. Alarmingly, this rate is similar to rates of hand hygiene compliance reported for the past few decades prior to the guidelines. The combination of an increasingly complex patient population, an exponentially increasing medical literature, and variations in physician awareness and interpretation of the available information lead to wide variations in care and adoption of beneficial treatments for our patients. This entails having support from the administration or supervisors for the project and identifying a project champion who functions as the team leader. Depending on the process involved, this may include physicians, nurses, respira to ry therapists, nutritionists, environmental staff or others. In particular, the aim statement should identify the intervention targeted with expected levels of change within a specified timeframe. The team will subsequently develop interventions that can affect one or several of the key drivers and lead to successful change to achieve the aim. Interventions to be tested should be specifically defined including how to measure compliance and what outcome to measure to determine success. Providing feedback to the involved staff will raise awareness about the intervention and lead to 491 self-driven motivation for improvement. Understanding reasons for non-compliance may identify barriers to implementation that need to be addressed or parts of the pro to col that may need to be adjusted. Simple checklists completed at the bedside can be used to collect data on intervention compliance [37]. This is typically achieved by providing continuous feedback to improve compliance with the intervention and either adjusting the intervention or adding a new intervention if maximum compliance with the initial intervention has been obtained. Successful adoption and maintenance of an intervention in to practice will establish new baseline levels or rates for the measured outcome.
