Rhabdoid tumor of the kidney is relatively rare but a highly lethal malignancy of infancy. Prenatal detection of a renal rhabdoid tumor with mesoblastic components has been achieved in a 27-week fetus (Fuchs et al, 2004). The tumor appeared as a large mass in the left renal area with concomitant massive polyhydramnios. Ultrasound features alone did not distinguish the tumor from a benign lesion, but aggressive growth of the tumor indicated malignancy. Leclair and colleagues (2005) reviewed outcome in 28 patients with prenatally diagnosed renal tumors from 20 institutions. One or more complications were identified in 20 of the 28 patients (71%) during the perinatal period. Polyhydramnios was observed in 11 fetuses (39%), 2 had hydrops fetalis, and 7 developed acute fetal distress necessitating emergency cesarean section, of which 1 died in utero before delivery. Median gestational age of the 27 neonates born alive was 35 weeks (range 29 to 39), including 13 of the 28 patients reviewed (46%) who were born before term. Complications at birth included hemodynamic instability in 3 neonates, respiratory distress syndrome in 8 (30%), and hypertension in 6 (22%). Surgical complications occurred in 7 patients (26%), including tumor rupture in 1 and intraoperative bleeding with postoperative death in 1. At median follow-up of 42 months, 26 of the 27 children were in complete remission. Leclair and colleagues concluded that prenatally diagnosed renal tumors have an excellent oncologic outcome but a high risk of perinatal complications. Prenatal diagnosis should allow planning the delivery at a pediatric tertiary care center to avoid a potentially lifethreatening condition in early neonatal life. If an overgrowth syndrome is suspected, further genetic analysis can be offered (Vora and Bianchi, 2009). Often, an inferior vena cava thrombus can be seen with decreased or no flow in the affected renal vein. The typical pattern of renal enlargement, loss of corticomedullary differentiation, echogenic streaks, lack of definition of renal sinus echoes, and loss of venous flow in the affected kidney by Doppler imaging was observed. After cesarean section, full recovery at 1 week and a normal evolution at 1 month of life were reported. According to Sherer and colleagues, the worldwide annual incidence of childhood adrenal cortical neoplasms ranges from 0. These neoplasms are even more unusual among infants, suggesting spontaneous resolution in some lesions, with only 23 cases reported in the literature (Sherer et al, 2008). The need for continued antenatal evaluation is debatable and unclear, particularly with mid- and late-trimester mild and moderate hydronephrosis. In the setting of severe unilateral or bilateral hydronephrosis, more regular follow-up is reasonable. If there is a suspicion of bladder outlet obstruction, regular follow-up is needed. In addition to normal fetal growth parameters, amniotic fluid volume, renal appearance (echogenicity, degree of hydronephrosis, cystic changes), and extrarenal fluid collections should be monitored closely. Curtis and colleagues (Sherer et al, 2008) developed an algorithm that facilitates the correct diagnosis of the suprarenal masses, subdiaphragmatic extralobar pulmonary sequestration, and neuroblastoma, allowing the correct diagnosis to be made prenatally in 95% of patients. Based on a literature review, the authors identified distinguishing features of the two lesions and created an algorithm on the basis of these distinctions. Typical findings on prenatal ultrasonography for subdiaphragmatic extralobar pulmonary sequestration include an echogenic mass that is left sided and can often be identified during the second trimester. Neuroblastoma is most often cystic, right sided, and identified in the third trimester. The echogenic right suprarenal mass became larger and hypoechoic on follow-up postnatal ultrasonography. With difficulty differentiating the lesion from cystic neuroblastoma, the authors performed a surgical exploration when the patient was 2 months old, and adrenal hemorrhage was confirmed, thus suggesting that adrenal hemorrhage can occur as early as the second trimester. RationaleandIndicationsforFetalIntervention Overall, the need to consider in utero intervention for obstruction is uncommon. However, in the specific cases in which it should be considered, the rationale for antenatal treatment of hydronephrosis is to maximize development of pulmonary and renal function. These two aspects of fetal development are closely linked because urine comprises more than 90% of amniotic fluid volume by the 16th week of gestation and because oligohydramnios during the second trimester is often associated with a lethal postnatal outcome secondary to pulmonary hypoplasia. Before prenatal surgical intervention for obstructive uropathy, it is critical to assess the risk-benefit ratio. The time of onset of oligohydramnios has been shown to be an important determinant of outcome (Mahony et al, 1985; Mandell et al, 1992b). Therefore, in the setting of late-onset oligohydramnios there appears to be limited usefulness of urinary tract decompression or early delivery for pulmonary reasons. It is also unclear whether early delivery to permit earlier postnatal urinary decompression is beneficial. If early delivery is considered, maternal corticosteroid administration for pulmonary development should be considered. Neonatology colleagues should also be involved in any early delivery decision process. The most widely accepted indicator of salvageable renal function is analysis of fetal urine.
Infection Infection remains a significant reason for clinical presentation of both ectopic ureters and ureteroceles antibiotics for dogs cuts buy discount ordipha 500mg online, which may occur at any age and have a highly variable pattern antibiotics for sinus infection and drinking order ordipha 100 mg with visa. The abnormality prompts postnatal imaging non prescription antibiotics for acne buy on line ordipha, which will invariably determine the specific cause antibiotics for sinus infection penicillin 500 mg ordipha amex, lead to further studies, and permit an adequate characterization of the condition. The prenatal imaging patterns are identical to those seen postnatally on ultrasound imaging, yet may be misinterpreted. While these are described in the chapter on prenatal diagnosis (Chapter 124), several elements should be emphasized. The identification of a duplex system prenatally may be difficult except when one of the moieties is dilated. The report of an upper pole "cyst" in a fetus should be interpreted as being upper pole Although there is great variability in the presentation of either ectopic ureter or ureterocele, there are several patterns that may be anticipated. In either case, generalized urosepsis may be the presenting clinical scenario, and a renal bladder ultrasound will usually provide the diagnosis. The extreme variability of quality of prenatal imaging makes this recommendation tenuous, and it would seem prudent that an ultrasound study be obtained in all children with urosepsis. The value of early detection is the potential for early treatment, which may be a simple drainage procedure. Ectopic ureters will frequently manifest with a less acute pattern evidenced by ongoing low-grade fever with periodic spikes. In some cases, a negative urine culture will be present simply because the infected ectopic system is not draining into the bladder. This clinical pattern should prompt an ultrasound study, which will usually reveal a dilated upper pole or entire system. It is rare for the unobstructed ectopic ureter to manifest with infection, but it is associated with incontinence. In boys, a similar generalized subacute pattern of infection may be present, but more often these boys have epididymitis on presentation. Although this may be an unusual subset of young boys with an acute scrotum, they will have a true bacterial epididymitis and may or may not have infected urine. In the setting of a suspicion for epididymitis in a young boy, it is prudent to perform a brief ultrasound examination of the upper tracts to ensure no abnormality (Rajfer et al, 1978; Umeyama et al, 1985; Chu et al, 2012). Older males will also present in this manner, although it is unclear why it may be so delayed. Some have had recurrent episodes of epididymitis before the underlying cause is detected. Prolapse Ureterocele prolapse is an unusual but distinctive presenting sign that may still confuse the clinician. These are usually smooth, congested mucosal-covered intralabial masses, and the child may be experiencing difficulty voiding. The mass protrudes from the urethra, distinct from the vagina, and is not circumferential as a urethral prolapse would be. An ultrasound examination of the bladder will usually confirm the diagnosis, and kidney images will further support this. Incontinence Clinical Patterns Urinary incontinence may be caused by an ectopic ureter in a girl, but not in a boy. The toilet-trained girl with verified continuous urinary leakage must be evaluated for an ectopic ureter. Imaging studies may not immediately detect this condition because the affected renal moiety may not be dilated, and the level of suspicion must be guided by a careful history and occasionally physical examination. Before toilet training it may be difficult to detect continuous incontinence, although some parents will note persistent dribbling during changing. Persistence will usually prompt evaluation, and the characteristic history can be obtained. When asked if the child can be dry for 30 to 60 minutes, the parent will usually say no. It is important to be cautious in questioning, because some parents with children who wet for other reasons may state, "She is always wet," when in fact the child can be dry for periods of time. The dampness associated with an ectopic ureter typically occurs throughout the day and does not relent. In rare patients it has been intermittent, perhaps caused by intermittent leakage through a membrane of Gartner duct. In older children in whom the diagnosis has not been recognized, attribution of the symptoms may be to dysfunctional voiding, laziness, and even sexual abuse (Lane, 1962; Carrico and Lebowitz, 1998). During the history taking, signs of typical voiding dysfunction such as voiding postponement, posturing, and constipation should be sought to assess likelihood of these being an explanation for the wetting. LatePresentation Presentation of both ectopic ureters and ureteroceles in the teen or adult has been reported, usually associated with infection or abdominal pain and rarely incontinence (Idbohrn and Sjostedt, 1954; Abrahamsson et al, 1981; Amitai et al, 1992; Westesson and Goldman, 2013). The nonobstructing ureterocele, often associated with a single system, is well recognized in the adult, often with a stone in the small ureterocele (Singh, 2007; Mizuno et al, 2008). Vaginal wall prolapse has also been associated with an ectopic ureter (Chai et al, 2014). In most cases of late presentation, upper pole nephrectomy may be the most appropriate management because there is usually little to no function associated with the affected renal moiety (Brehmer et al, 2007; Mason et al, 2012). In some cases, urine cultures will be negative because the infected ectopic system is not draining into the bladder.

Testosterone supplementation improves verbal fluency (Alexander et al, 1998), but other controlled studies have found no effect of such supplementation on memory (Sih et al, 1997). Compared to tests for other cognitive domains, tests for spatial ability uniquely declined in men on intermittent hormone therapy (Cherrier et al, 2003). Chapter120 HormonalTherapyforProstateCancer 2795 cumulative incidence of cardiovascular death was 5. Since lean body mass usually decreases by the same magnitude, the weight gain is largely due to an increase in fat mass (Levy et al, 2008). Regular vigorous exercise may help patients limit the accumulation of fat and even prevent prostate cancer progression. Gynecomastia (an increase in breast tissue) and mastodynia (breast tenderness) may occur together or independently. Likewise, the peripheral conversion of testosterone to estradiol associated with the antiandrogens induces gynecomastia at high rates: 66. Liposuction and subcutaneous mastectomy have been used to treat established gynecomastia (Higano, 2003). The selective estrogen receptor modulator tamoxifen has been used to treat mastodynia (Serels and Melman, 1998). Compensatory mechanisms limit the symptomatic effects of anemia to a small subset (13%) of men (Strum et al, 1997). Whatever the etiology, clinically, patients respond to recombinant human erythropoietin. In some cases, most notably external beam radiotherapy, the combination clearly improves the outcomes; in others, most notably radical prostatectomy, there is no obvious benefit. It should be noted that the benefit appears to be in men with locally advanced disease and/or those with high-grade, high-risk disease. These observations were supported by another study randomizing men with locally advanced prostate cancer to radiation alone versus radiation combined with goserelin for 3 years (Bolla et al, 1997). The significant disease-free and overall survival advantage of the combination was confirmed at a long-term analysis of the trial. Changes in the dose and field of the external beam radiation therapy make direct study-to-study comparisons difficult: unlike the uniformity of radical prostatectomy (complete ablation of the prostate), the optimum radiation technique remains undefined.

The fact that serum testosterone does not drop to zero following surgical or medical castration is clear evidence for additional sources of androgen (Geller, 1985; Sandow et al, 1988). The idea of trying to eliminate all sources of endogenous androgen in treating prostate cancer is not new: bilateral surgical adrenalectomy was performed with failure far outweighing success (Huggins and Scott, 1945). The combination therapy resulted in a significantly longer progression-free survival and longer overall median survival (35. In a hypothesis-generating subset analysis, the authors found that those patients with minimal metastatic disease (defined as the absence of metastases in the skull, ribs, long bones, and non-nodal soft tissue) enjoyed the largest survival benefit compared to similarly defined men receiving placebo. Another positive study compared orchiectomy plus the antiandrogen nilutamide to orchiectomy plus placebo (Dijkman et al, 1997): at 8. When several studies testing the same idea in presumably the same patient population demonstrate both positive and negative results, concerns about the existence of a real treatment effect increase. In these 27 studies, 88% of patients had metastatic disease; the remainder had locally advanced disease. Interestingly, in studies recording specific cause of death, 20% died from causes other than prostate cancer: not everyone with metastatic prostate cancer dies from the disease. When studies examining the outcomes of the nonsteroidal antiandrogens flutamide or nilutamide were considered independent of those with cyproterone acetate, the 5-year survival improved from 24. Unfortunately, the clinical data to support the various perspectives are limited and it is not uncommon for proponents of a particular opinion to extrapolate data from one clinical state to another for which data do not exist. First, the natural history of prostate cancer progression, even in the hormonally intact individual, is protracted. In a cohort of 304 men with a biochemical recurrence after radical prostatectomy, the median time from recurrence to metastasis was 8 years and from metastasis to death was 5 years (Pound et al, 1999). In 1973, the results of a large (more than 1900 men) study performed in the Veterans Administration of early versus late hormonal therapy were reported (Byar, 1973). In men with metastatic disease, death from prostate cancer occurred in 48% of those treated early versus 47% of those treated late. In men with locally advanced disease, death from prostate cancer occurred in 14% of those treated early versus 17% of those treated late. The lack of a survival benefit in men treated early coupled with the known side effects of therapy support the recommendation that hormonal therapy should be instituted in men with symptomatic disease.
