Kidney and urological involvement in Down syndrome: frequent, underestimated, but associated with impaired quality of life and risk of kidney failure. Pediatr Nephrol 2024; 39:347-355. [PMID: 37386331 DOI: 10.1007/s00467-023-05986-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 04/08/2023] [Accepted: 04/10/2023] [Indexed: 07/01/2023]
Abstract
Patients with Down syndrome (DS) are at risk of multiorgan dysfunction; kidney and urological impairment are common. This is due to a likely increased risk of congenital kidney and urological malformations (odds ratio of 4.5 compared to the general population in one study), more frequent associated comorbidities at risk of kidney dysfunction (such as prematurity in 9-24% of children, intrauterine growth retardation or low birth weight in 20%, and congenital heart disease in 44%), and more frequent lower urinary tract dysfunction (reported in 27-77% of children with DS). If present, malformations and comorbidities at risk of kidney dysfunction warrant regular kidney monitoring in addition to their treatment. Serum creatinine in children with DS has been shown to be higher than in the general population and asymptomatic hyperuricemia is reported in 12-33% of children or young adults with DS. Moreover cryptorchidism and testicular cancer are also more common and should be detected by clinical examination. Thus, persons with DS at risk of presenting kidney and urological impairment should be identified by prenatal ultrasonography, comorbidities at risk of kidney sequelae considered, and during regular medical follow-up, clinically examined and questioned to diagnose testicular anomalies and lower urinary tract dysfunction. This is of importance as such kidney and urological impairments are associated with impaired quality of life and mental health, and risk of kidney failure.

Incidence of testicular microlithiasis after orchidopexy for cryptorchidism and its risk factors: A retrospective cohort study. J Pediatr Urol 2022; 18:377.e1-377.e5. [PMID: 35469770 DOI: 10.1016/j.jpurol.2022.03.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Revised: 03/25/2022] [Accepted: 03/28/2022] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Testicular microlithiasis (TML) is detected using scrotal ultrasound (US) and is characterized by hyperechoic non-shadowing foci 1-3 mm in diameter within the testicular parenchyma. Although a history of orchidopexy is a known risk factor for TML, and TML is a relatively common condition in postoperative cryptorchidism patients, no previous report has focused on risk factors for TML after orchidopexy. OBJECTIVE The aims of this study were to evaluate the time-dependent incidence of TML after orchidopexy for cryptorchidism and to identify risk factors for TML. STUDY DESIGN This study included patients who underwent primary orchidopexy for cryptorchidism between 2004 and 2018 and could be evaluated using scrotal US before and after the procedure. Patients with chromosomal abnormalities and those with preoperative TML were excluded. The Kaplan-Meier method was used to assess postoperative TML appearance. The Cox proportional hazard model was used to evaluate three potential risk factors for postoperative TML: higher testicular position (proximal to the external inguinal ring), delayed orchidopexy (after 18 months of corrected age), and bilateral cryptorchidism. RESULTS A total of 214 testes from 163 patients were eligible for inclusion (operative age and follow-up time: 2.2 years ± 18 months and 6.3 years ± 46 months, respectively). TML was found in 14/163 patients (8.6%) and 17/214 testes (8.1%). No testicular tumors were discovered during follow-up. The time-dependent TML incidence was 6.0% at 5 years and 11.2% at 10 years after surgery (Summary figure). A higher testicular location proximal to the external inguinal ring was found to be an independent risk factor in the Cox proportional hazard model (hazard ratio 6.18, 95% confidence interval 1.37-27.9, Summary figure). DISCUSSION Our findings show that the incidence of postoperative TML increases for approximately 10 years following orchidopexy and is associated with a higher testicular location proximal to the external inguinal ring at surgery. In the adult population, TML with a history of cryptorchidism is a known risk factor of testicular malignancy. Given that more than 20% of boys with a higher testicular position developed TML, US evaluation to detect TML during pubety is feasible for the patients with a history of orchidopexy. CONCLUSION The incidence of postoperative TML in boys with cryptorchidism rises until puberty and is strongly associated with a higher testicular position at orchidopexy.

Abstract
INTRODUCTION The exact correlation of testicular microlithiasis (TM) with benign and malignant conditions remains unknown, especially in the paediatric population. The potential association of TM with testicular malignancy in adulthood has led to controversy regarding management and follow-up. OBJECTIVE To determine the prognostic importance of TM in children in correlation to the risk of testicular malignancy or infertility and compare the differences between the paediatric and adult population. STUDY DESIGN We performed a literature review of the Medline, Embase and Cochrane controlled trials databases until November 2020 according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) Statement. Twenty-six publications were included in the analysis. RESULTS During the follow-up of 595 children with TM only one patient with TM developed a testicular malignancy during puberty. In the other 594 no testicular malignancy was found, even in the presence of risk factors. In the adult population, an increased risk for testicular malignancy in the presence of TM was found in patients with history of cryptorchidism (6% vs 0%), testicular malignancy (22% vs 2%) or sub/infertility (11-23% vs 1.7%) compared to TM-free. The difference between paediatric and adult population might be explained by the short duration of follow-up, varying between six months and three years. With an average age at inclusion of 10 years and testicular malignancies are expected to develop from puberty on, testicular malignancies might not yet have developed. CONCLUSION TM is a common incidental finding that does not seem to be associated with testicular malignancy during childhood, but in the presence of risk factors is associated with testicular malignancy in the adult population. Routine monthly self-examination of the testes is recommended in children with contributing risk factors from puberty onwards. When TM is still present during transition to adulthood a more intensive follow-up could be considered.

Abstract
Abstract
Background
Testicular microlithiasis in children was defined for the first time in 1961 based on histological criteria. There should be more than 5 calcifications per testicle in order to say that the patient has testicular microlithiasis. It has three different echographic grades depending on the number of calcifications. However, this disease is uncommon, with inaccurate prevalence and no certain information about its evolution or etiology.
Main body
We studied 4 clinical cases of children diagnosed with testicular microlithiasis, in light of the conducted review of the literature, and we defined the characteristics of this disease and proposed a management and monitoring framework based on the clinical observations.
Conclusion
There is a link between testicular microlithiasis and testicular cancer. Therefore, it is recommended to make a regular follow-up of children who present testicular microlithiasis with the presence of risk factors.

Abstract
Background Testicular microlithiasis and its clinical significance are not fully understood. Testicular microlithiasis and risk factors have been associated with testicular cancer. The role of testicular microlithiasis is investigated. Purpose To investigate the association between testicular microlithiasis and socioeconomic and other pre-diagnostic factors. Material and Methods All men who had a scrotal ultrasound examination at the Department of Radiology, Vejle Hospital, during 2001–2013 were included. They were categorized as patients with and without testicular microlithiasis and compared with pre-diagnostic data from a nationwide registry. A total of 2404 men (283 [11.8%] with testicular microlithiasis and 2121 [88.2%] without testicular microlithiasis) were included. The association between testicular microlithiasis and pre-diagnostic conditions was investigated with logistic regression. Results Overall, we found no statistically significant differences in demographics, socioeconomic characteristics, or testicular diseases in men with and without testicular microlithiasis. Men with testicular microlithiasis had more often been treated for infertility (odds ratio [OR] 2.09, 95% confidence interval [CI] 0.84–5.24) and testicular torsion (OR 1.58, 95% CI 0.34–7.36) compared to men without testicular microlithiasis. We found no association between sexually transmitted diseases and testicular microlithiasis. Conclusion Treatment for infertility and torsion was non-significantly associated with testicular microlithiasis and no other association was found. These data do not suggest early exposure is related to testicular microlithiasis.

Abstract
Brain tumors are the most common solid neoplasms of childhood, but they are very rarely reported in children with Down Syndrome (DS), who develop more commonly different types of malignancies. In particular, we hereby report the case of an 8-years-old child with DS that presented to our attention for neurological and endocrinological issues. Brain imaging revealed the presence of a mass that was partially resected revealing a histological diagnosis of Pleomorphic Xanthoastrocytoma (PXA), a rare WHO grade II tumor extending from the diencephalic region into the surrounding brain tissue. These tumors can harbor the BRAF mutation p.V600E, targetable by the specific inhibitor Vemurafenib. After confirming the presence of the mutation in the tumor, the patient was treated with Vemurafenib. The treatment proved to be effective, leading to a partial response and a stabilization of the disease. Usually, in patients with DS a reduction of the dose of chemotherapeutic drugs is necessary. Vemurafenib was instead well-tolerated as the only observed adverse effect was grade I skin toxicity. This is, to our knowledge, the first case of a PXA reported in a child with DS and the first DS patient treated with Vemurafenib.

Abstract
INTRODUCTION Testicular microlithiasis (TM) is a condition characterized by calcium deposits within the testis, usually detected incidentally during ultrasonography of the scrotum. TM has been associated with the presence of, and possibly the development of, testicular malignancy. Our aim was to document international clinical management practices for TM and to analyze what factors and perception of risk influence conservative versus active management and follow-up. METHODS European Society for Paediatric Urology (ESPU) and Society for Pediatric Urology (SPU) members were invited to complete an online case-based survey of clinical management practices of TM. Eight cases had a single variable changed each time (classic versus limited TM, unilateral versus bilateral, prior cryptorchidism versus no cryptorchidism) to ascertain the provider's perception of risk. The respondents completed multiple choice questions on initial management, follow-up plan, length and interval of follow-up. Multivariate logistic regression was performed to determine factors associated with decisions on management and follow-up. RESULTS There were 265 respondents to the survey from 35 countries (Table). Median time in practice was 13 years. Factors that were significantly associated with more aggressive initial management (more than counseling on self-examination) included: not yet in independent practice, low volume TM cases per year, those practicing pediatric and adult urology, classic appearance of TM and cryptorchidism. Factors that were significantly associated with urologist follow-up and active investigation included: European practitioners, low TM case volume per year, those practicing both pediatric urology and pediatric surgery, classic TM appearance and a case history of cryptorchidism. Interval and length of follow-up was wide-ranging, with most respondents favoring annual follow-up. CONCLUSION Management of TM varies and a mix of surgeon and case factors significantly influences management strategies. This baseline understanding of the lack of systematic management suggests the need for the development of consensus guidelines and prospective study.

Abstract
Introduction: We present a retrospective 2-year follow-up cohort of 103 men with testicular microlithiasis (TML) and discuss patient compliance and the value of surveillance. Methods: A retrospective analysis of patients examined with scrotal ultrasonography (US) in the period from 2008 through 2010 was performed. A total of 103 men with TML were diagnosed and offered US follow-up every 6 months for 2 years. They were retrospectively analyzed regarding demographics and follow-up details, including the development of any kind of malignancy until March 2015, using the Danish Electronic Pathology Registry. Results: The prevalence of TML was 10.3%. Of the 103 men with TML, 23 (22.3%) had TML in the left testicle, 38 (36.9%) in the right (p=0.002), and 42 (40.8%) had bilateral TML. Patient compliance was low with 11.7% participating in all US follow-up examinations. 5 men presented risk factors (testicular atrophy (N=1) and previous testicular cancer (N=4)), but no cases of testicular malignancy were found in the follow-up period. Conclusion: The low patient compliance conflicts with the ESUR Scrotal Imaging Subcommittee guidelines that recommend scrotal US follow-up annually for TML until the age of 55 years. The fact that no cancers were found during follow-up using the pathology registry calls the value of follow-up into question.

Abstract
Although MAMLD1 on chromosome Xq28 is known as a causative gene for 46,XY disorders of sex development, clinical information is virtually limited in patients of infancy to early childhood. Here, we report long-term genital and hormonal findings in three previously described Japanese patients with MAMLD1 mutations, i.e., patients 1 and 2 with p.E197X and patient 3 with p.R726X. As previously reported, patients 1-3 exhibited penoscrotal hypospadias with chordee, microphallus, bifid/hypoplastic scrotum, and/or bilateral cryptorchidism/retractile testes, in the presence of sufficiently high serum basal or hCG-stimulated testosterone values in the mini-pubertal period to early childhood. Subsequently, patient 1 had low serum hCG-stimulated testosterone value (126 ng/dL) at 13 11/12 years of age, and manifested microphallus (4.5 cm), relatively small testes (left 8 mL and right 10 mL), Tanner stage 3 genitalia and pubic hair development at 18 3/12 years of age. Similarly, patients 2 and 3 showed mild hypergonadotropic hypogonadism at 7 0/12 and 9 9/12 years of age, respectively, with serum GnRH-stimulated LH values of 5.5 and 7.2 mIU/mL and FSH values of 10.3 and 19.8 mIU/mL and hCG-stimulated testosterone values of 70 and 80 ng/dL, respectively. Testis ultrasound studies delineated microlithiasis in patients 1 and 3. These results imply for the first time deterioration of testicular function with age in patients with pathologic MAMLD1 mutations.

Abstract
Down syndrome (DS) is the most common aneuploidy of chromosome 21, characterized by the presence of an extra copy of that chromosome (trisomy 21). Children with DS present with an abnormal phenotype, which is attributed to a loss of genetic balance or an excess dose of chromosome 21 genes. In recent years, advances in prenatal screening and diagnostic tests have aided in the early diagnosis and appropriate management of fetuses with DS. A myriad of clinical symptoms resulting from cognitive, physical, and physiological impairments caused by aberrations in various systems of the body occur in DS. However, despite these impairments, which range from trivial to fatal manifestations, the survival rate of individuals with DS has increased dramatically from less than 50% during the mid-1990s to 95% in the early 2000s, with a median life expectancy of 60 years reported recently. The aim of this narrative review is to review and summarize the etiopathology, prenatal screening and diagnostic tests, prognosis, clinical manifestations in various body systems, and comorbidities associated with DS.

Abstract
BACKGROUND Ultrasonography of the testis is a well-established diagnostic tool in detection of testicular microlithiasis (TML). Operator-dependent diagnostic variation related to skill, knowledge, and operator consistency are factors that influence detection of TML. PURPOSE To determine inter- and intraobserver agreement for detection of TML using ultrasonography for a group of physicians with no or limited experience compared to a group of experience senior radiologists. MATERIAL AND METHODS Between May and September 2014 a total of six observers evaluated 34 patients scrotal ultrasonography recorded from September to December 2013. The observers were blinded to patient history and previous ultrasonography. Three of the observers had no or limited experience with detection of TML, and three of the observers had more than 15 years of experience. Each observer reviewed all the scrotal ultrasonography recordings twice with a time interval of 3 months. RESULTS The inter-observer agreement showed substantial agreement and up to almost perfect agreement (κ = 0.86). Both the experienced and less experienced observers had a higher agreement in detecting and grading TML in their second reading. CONCLUSION The ultrasonography grading system of TML in this study showed to be reproducible, with an inter- and intraobserver agreement ranging between substantial agreement and up to almost perfect agreement with many years of experience not necessarily being essential.

Abstract
Testicular microlithiasis (TM), a rare condition characterized by calcification within the seminiferous tubules, is associated with benign and malignant disorders of the testis. We review current practices of following up pediatric patients diagnosed TM incidentally on scrotal ultrasonography (US). We analyzed retrospectively patient characteristics, family history, indications for US, pathological features, US findings, outcome, and follow-up. At our institution, 2875 scrotal US examinations were performed on 2477 children with various scrotal complaints from 2008 to 2015. Testicular microlithiasis was detected in 81 patients (i.e., an incidence of 3.27%). Every 6 months, each patient underwent a clinical and ultrasonographic evaluation as well as serum tumor markers determination to detect a potential malignancy. Seventy-eight patients who had undergone scrotal US at least twice were included in this study. We evaluated the US studies for the type of TM (diffuse and focal) and change in follow-up studies. Testicular microlithiasis was typically diffuse (n = 56, 71.8%) and bilateral (n = 45, 57.7%), and it was detected the most frequently in the 9-11-year age group (27 patients, 34.6%). The most common comorbid conditions included undescended testes (31 patients, 39.7%) and hydrocele (11 patients, 14.1%). We found that serum tumor markers were within normal limits both at diagnosis and upon follow-up. No testicular tumors or new abnormal symptoms developed during the clinical follow-up. There is no convincing evidence that TM alone is premalignant in a pediatric population. In terms of follow-up, we advise regular self-examinations and annual US in the absence of risk factors.

Abstract
The aim was to perform a systematic review to evaluate the published data on testicular microlithiasis (TM) in the pediatric population and to explore the association of TM with testicular malignancy as well as to propose guidelines to aid decision making on pediatric patients with TM. Outcome data for pediatric TM should be interpretated with caution due to the poor quality evidence available. Whilst the link with testicular neoplasms is undisputed (<5%) active screening programmes require robust evidence to support their wider deployment. Testicular self-examination though would appear advisable for all patients with testicular microlithiasis.

Abstract
Abnormal expression of solute carrier family 34 (sodium phosphate), member 2 (SLC34A2) in the lung may induce abnormal alveolar type II (AT II) cells to transform into lung adenocarcinoma cells, and may also be important in biological process of lung adenocarcinoma. However, at present, the effects and molecular mechanisms of SLC34A2 in the initiation and progression of lung cancer remain to be elucidated. To the best of our knowledge, the present study revealed for the first time that the expression levels of SLC34A2 were downregulated in the A549 and H1299 lung adenocarcinoma cell lines. Further investigation demonstrated that the elevated expression of SLC34A2 in A549 cells was able to significantly inhibit cell viability and invasion in vitro. In addition, 10 upregulated genes between the A549-P-S cell line stably expressing SLC34A2 and the control cell line A549-P were identified by microarray analysis and quantitative polymerase chain reaction, including seven tumor suppressor genes and three complement genes. Furthermore, the upregulation of complement gene C3 and complement 4B preproprotein (C4b) in A549-P-S cells was confirmed by ELISA analysis and was identified to be correlated with recovering Pi absorption in A549 cells by the phosphomolybdic acid method by enhancing the expression of SLC34A2. Therefore, it was hypothesized that the mechanisms underlying the effect of SLC34A2 on A549 cells might be associated with the activation of the complement alternative pathway (C3 and C4b) and upregulation of the expression of selenium binding protein 1, thioredoxin-interacting protein, PDZK1-interacting protein 1 and dual specificity protein phosphatase 6. Downregulation of SLC34A2 may primarily cause abnormal AT II cells to escape from complement-associated immunosurveillance and abnormally express certain tumor-suppressor genes inducing AT II cells to develop into lung adenocarcinoma. The present study further elucidated the effects and mechanisms of SLC34A2 in the generation and development of lung cancer.

Abstract
OBJECTIVE: To discuss the relationship between testicular microlithiasis and testis tumors in
children and to consider the chances of testis preserving surgery in specific
cases. CASE DESCRIPTION: Pre-adolescent presenting testicular microlithiasis and a larger left testis,
corresponding to a cystic testicular tumor. The tumor was excised, with
ipsilateral testis preservation. Histology diagnosed a testis dermoid tumor. COMMENTS: The relationship between testis tumors and testicular microlithiasis is ill
defined in children. Pediatric urologists need to develop specific follow-up
protocols for pre-pubertal children.

Abstract
Previously considered to be a benign finding on scrotal ultrasonography, testicular microlithiasis (TM) is now recognized as a condition associated with the development of testicular neoplasia. Despite this the management of TM remains unclear. We review the evidence for this association and suggested management strategies.

Abstract
OBJECTIVE After review of the pediatric literature, we report on the prevalence of testicular microlithiasis and its relation with benign and malign entities. We provide a guideline for the management of boys with testicular microlithiasis. MATERIALS AND METHODS The databases searched were Medline, Web of Science, Embase and the Cochrane Library. Data on the rates of testicular microlithiasis were collected and from each study information was extracted on the study population according to country, study design, diagnostic method, type of patient, number of patients, age, associated anomalies, additional diagnostic methods and follow-up information. From the 472 articles, we selected 126 articles as potentially relevant, of which 57 were included. RESULTS In asymptomatic boys, the prevalence of testicular microlithiasis is 4.2% and in symptomatic referrals it is 1.6%. The development of a testicular malignancy is occasionally reported after diagnosis of testicular microlithiasis. The management of boys with testicular microlithiasis varies widely. Most authors recommend regular self-examination, and some perform testicular ultrasound and/or screen tumor markers. CONCLUSION The prevalence of testicular microlithiasis in boys varies between 1.1% and 4.2%. For follow-up, regular self-examination is advised from the age of 15 years.

Abstract
Ultrasound is a vital adjunct to clinical examination in diagnosing scrotal disease, as a number of different processes may present similarly. Potential applications range from the acute emergency to long-term screening as well as cases in which a distinct scrotal abnormality may or may not be palpable. Differentiating acute epididymitis/epididymoorchitis from testicular torsion is possible sonographically, thereby guiding appropriate medical or surgical management. Distinguishing between cystic, solid, or complex scrotal masses is readily performed with this modality. It clearly depicts simple versus complex hydroceles and determines the presence of underlying testicular or epididymal disease. Not only is ultrasound the best imaging modality for longitudinal screening in patients (testicular microlithiasis, cryptorchidism) at risk for testicular tumors, it also provides valuable information in the infertile male by documenting the presence or absence of a varicocele.
