She did not have features of protein catabolism like striae quality naproxen 250 mg arthritis in feet how to treat, bruise purchase 500 mg naproxen amex arthritis and osteoporosis, and proxi- mal myopathy or any stigma of acromegaly 500 mg naproxen sale arthritis pain causes. In addition generic 250 mg naproxen fast delivery rheumatoid arthritis disease, there were bilateral bulky ovaries with multiple tiny cystic areas suggestive of polycystic ovaries. At 6 weeks of follow-up, her hirsute score was same, but the frequency of cosmetic mea- sures was reduced. Unfortunately our patient never had a thorough evaluation for the etiological diagnosis. The differential diagnosis in this scenario includes androgen-secreting adrenal or ovarian tumors, ovarian hyperthecosis, Cushing’s syndrome, and use of androgens or androgenic progestins. Slow and pro- gressive development of features of virilization without any defeminization and lack of palpable abdominal or pelvic mass virtually excludes the possibility of androgen- secreting ovarian or adrenal malignant tumors. Virilization with defeminization is usu- ally seen with severe and rapid-onset hyperandrogenism and denotes the presence of androgen-secreting ovarian or adrenal malignant tumors. Ovarian hyperthecosis is unlikely as these patients commonly present in the postmenopausal period with severe manifestations of hyperandrogenism. Possibility of Cushing’s syndrome in our patient was low as she did not have any mani- festations of protein catabolism. Size of the adrenal tumor was >4 cm in the index patient, and the probability of malignancy with a tumor size between 4. The biochemical improvement precedes clinical improvement by weeks to months as shed- ding of preexisting hair depends on the duration of hair cycle, as seen in our patient. Androgens are normally produced by the ovary and adrenals in women, but when it is associated with clinical features and/or biochemical evidence of androgen excess, they constitute “disorders of androgen excess. The clinical manifestations of androgen excess are hirsutism, acne, androgenic alopecia, low-pitch voice, male torso, and clitoromegaly. The features of virilization in a woman include androgenic alopecia, acne, low- pitch voice, male torso, and clitoromegaly. These are the manifestations of severe androgen excess and are due to ovarian/adrenocortical malignancy or ovarian hyperthecosis. The features of defeminization include breast atrophy, oligomenorrhea/amenor- rhea, and loss of gluteofemoral adiposity. These are the features of estrogen defi- ciency; however, they may be present with severe virilization, as androgen excess interferes with the binding of estrogen to its nuclear receptor. In a rapidly grow- ing androgen-secreting tumor, features of defeminization precede virilization. Hirsutism is defined as excessive terminal hair growth in “male pattern” in an androgen-dependent area in a woman. The “male pattern” hair should not be considered synonymous with “hair in androgen-dependent areas” as axillary and pubic hair common to both men and women are also present in an androgen- dependent area but are not included in the “male pattern. The terminal hair are thick, coarse, and pigmented and are present in androgen-dependent areas as opposed to vellus hair which are fine, thin, and unpigmented and are distributed all over the body. Hair present in almost all areas of the body is androgen dependent except eye- brows, eyelashes, nostrils, and lateral and occipital scalp hair (asexual hair). The axillary and pubic hair are common to both gender and are sensitive to low levels of androgen (ambosexual hair). However, hair on the upper lip, chin, chest, upper arms, abdomen, back, and thighs require a higher level of androgens and characterize the “male pattern” (sexual hair). On the contrary, scalp hair are the only exception where androgen excess results in regression. This is due to short- ened anagen phase and possibly androgen receptor downregulation. Most of the hair in women are androgen dependent, but some hair are estrogen dependent, e. This is evident by maximal scalp hair growth seen during pregnancy, and it occurs due to prolongation of the anagen phase because of estrogen. Further, despite normal adrenarche, pubarche is absent in patients with hypogonadotropic hypogonadism and Turner’s syndrome as adrenal andro- gens act in concert with estrogen for the appearance of pubic and axillary hair. This is evidenced by the absence of hair in these areas in patients with 5α-reductase deficiency. However, there is a poor correlation between hair growth and serum androgen 130 6 Disorders of Androgen Excess levels as hair growth also depends on local growth factors and end-organ sensi- tivity. Hair follicular growth is a continuous process characterized by a period of growth (anagen), transition (catagen), and rest (telogen). The anagen phase for scalp hair usually lasts for 2–6 years followed by the catagen phase lasting for 1–2 weeks and finally ends into the telogen phase for 4–6 weeks. Estrogen regulates the anagen phase of the scalp hair and is responsible for longer hair in women. Ovary and adrenal are the primary source of androgens, and adipose tissue is involved in the peripheral conversion of weaker androgens (e. Therefore, pathogenic abnormalities causing hirsutism involve ovary, adrenal gland or adipose tissue. Other endocrine disorders associated with hirsutism include Cushing’s syndrome, acromegaly, and hyper- prolactinemia. Drugs causing hirsutism are phenytoin, minoxidil, cyclosporine, diazoxide, and androgens or androgenic progestins. Idiopathic hirsutism is the diagnosis of exclusion and is characterized by regular menstruation, normal androgen profile, and no ovarian or adrenal abnormalities. Modified Ferriman–Gallaway score is an objective score to define hirsutism, and a score >8 is considered as significant. A score of 8–15 is classified as mild hirsutism and >15–36 as moderate to severe hirsutism. However, this data is derived from Caucasian women and has not been validated in other racial/ ethnic groups. It is observer dependent as the grading from 0 to 4 is subjective and does not include hair growth on side burn, nape of the neck, and phalangeal and perianal region. In addition, a woman having significant hair growth over upper lip/chin but may still have a total score of <8; thus, this score does not reflect the cosmetic concern of the patient. The classic syndrome originally described by Stein–Leventhal was based on the histomorpho- logical description of the ovary. The usual menstrual irregularities are oligomenorrhea or secondary amenorrhea and sometimes primary amenorrhea or menorrhagia. Anovulation and poorly estrogenized endometrium are the causes for primary amenorrhea. Menorrhagia is a rare pre- sentation which occurs due to endometrial hyperplasia and manifests as irreg- ular breakthrough bleeding. It is a consequence of unopposed estrogen action and deficient progesterone production due to chronic anovulation/luteal phase defects.

Franklin Introduction Over the past 70 years, since the first surgical palliation for tetralogy of Fallot by Drs. These patients continue to present a challenge for both pediatric and adult care providers. There continues to exist controversies as to where to best care for these complex patients. While these adults may logically be best cared for, and currently receive most of their care, in adult healthcare settings, the expertise in these complicated congenital heart lesions often resides at pediatric institutions. Given these issues, many organizations over the past decade have begun to focus on the need to transition and transfer these survivors of chronic childhood disease. This chapter will discuss the reasons for transition and transfer of care as well as suggesting some specific approaches. It must be emphasized that there is not a “one- size-fits-all” approach to this process. Each provider and/or center must work with the resources (and regulations) in place to develop an approach that works best given their local circumstances. In a 1993 position paper of the Society for Adolescent Medicine, transition was defined as “the purposeful, planned movement of adolescents and young adults with chronic physical and medical conditions from child- centered to adult-oriented health-care systems (6). Apart from these requirements, transfer is still recommended for several reasons, related to the physical and mental growth that occurs as patients reach adulthood. In addition, there are only approximately 150 pediatric cardiology fellowship positions available annually compared to approximately 2,000 adult cardiology fellowship positions (10). Moreover, many younger pediatric cardiologists may be uninterested in caring for a growing percentage of adult patients. Adult-Centered Healthcare Benefits Pediatric providers are often unable (and sometimes unwilling) to care for problems that are typically not encountered until adulthood. Adult providers are often much more accustomed (and may be better equipped) to provide care for patients with these issues. However, they typically report a low frequency of health maintenance care and counseling regarding contraception, pregnancy, and obesity prevention (12). In addition to the physical healthcare benefits that these patients may experience with adult-oriented care, transfer in care offers mental and emotional benefits to the patient, possibly related to the process of maturing into adulthood (8,14). If the choice (if available) is made to not transfer a patient to an adult provider, the P. The age at which the transition process begins varies widely throughout the world. As previously defined, transition involves a process that prepares the adolescent or young adult for transfer of care. This educational and experiential process must occur over an extended period to allow gradual growth in patient understanding, maturity, and autonomy. Given this, it is generally recommended that the transition process formally starts in early adolescence. In general, most guidelines recommend starting the formal transition process between 12 to 14 years of age (8,9,16,17,18). This allows the transition process to culminate in the transfer of care some time within the 18- to 21-year age range. Formal Transition Ideally, patients should be involved in a formal transition program that provides uninterrupted health care that is patient-centered, comprehensive, age and developmentally specific, and flexible. Transition and transfer should be viewed as another step in the process and as an inevitable occurrence (4,9,16). The transition policy should ideally be institution-wide and predictable so patients and providers understand that it is a planned and coordinated progression (4,7). This undoubtedly takes years to complete and should be started in the early teenage years. The first step, sometimes referred to as “envisioning a future,” involves giving the child and his/her family opportunities to think about the child as an adult. This plants the seed for lifelong follow-up as well as the expectation of an independent future (8,16). This can be considered as “pretransition” or preparation for transition in that it should occur during visits throughout early childhood. This involves discussing the expectations of a future with the ability to live an independent life and can begin to emphasize the need for a healthy, active lifestyle as well as the likely need for lifelong cardiac follow-up (4,7). Overall this process involves many components to help ensure an appropriate and successful transition and eventual transfer of care. One of the most important goals of a transition process is to ensure continuous care for the patient and his/her family.

Linking pediatric obesity to subclinical alterations in cardiac structure and function. Friedberg Quantification of Chamber Dimensions and Cardiac Structures Accurate measurements of valves, chambers, and vessels are essential to the diagnosis and management of patients with congenital and pediatric heart disease. The adult guidelines were recently revised to include three- dimensional (3-D) echocardiography and myocardial deformation imaging (4). One of the important differences between measurements in adult and pediatric patients is the effect of growth or body size on measurements. To overcome this limitation, the use of z-scores has been proposed as a practical alternative (5). Z-scores for different cardiovascular structures have been published (6,7) but the effect of gender and race on cardiovascular measurements may necessitate establishing normal values based on population mix seen in a specific laboratory. Detailing the measurement of each individual cardiovascular structure is beyond the scope of this chapter. In this chapter, the evaluation of cardiac function and chamber quantification are discussed in more detail. M-mode measurements have a very high temporal resolution albeit at the expense of low spatial resolution. If the measurements are not well standardized, M-mode measurements can be highly variable. This study showed poor agreement between the core laboratory and local laboratory measurements with relatively wide limits of agreement. Especially at high heart rates, the identification of the frame representing end systole and end diastole can be more variable. Another limitation is that currently the majority of published normal z-score data are based on M-mode measurements and not on 2-D imaging. M-mode measurement is obtained from a parasternal short-axis view of the left ventricle just inferior to the mitral valve leaflets. Three-dimensional echocardiography overcomes this problem as full 3-D volumetric data sets can be acquired including the entire ventricle. This results in improved reproducibility as it eliminates observer bias in determining endocardial borders.
