Cryptorchidism in Boys With Cerebral Palsy Is Associated With the Severity of Disease and With Co-Occurrence of Other Congenital Anomalies

A case of testicular cancer in a long-term hydranencephaly survivor with undescended testes

Introduction

The development of malignant tumors in patients with hydranencephaly is extremely rare. We describe the first case of testicular cancer that developed in the undescended testes of a long-term survivor of hydranencephaly.

Case presentation

A 32-year-old man with severe cerebral palsy due to hydranencephaly was referred to our department for the evaluation of a subcutaneous lump in the lower right abdomen. He was a long-term survivor of hydranencephaly. After confirming the diagnosis of right testicular cancer originating in his undescended testes, surgical resection was performed. Pathological examination revealed a mixed-type germ cell tumor.

Conclusion

The decision-making process for treating malignant tumors, like testicular cancer, in adults with severe cerebral palsy can be challenging. Clinical ethics consultation could be helpful in avoiding treatment delays.

Association between lower limb spasticity and cryptorchidism in males with cerebral palsy

AIM

To explore the association between presence and severity of lower limb spasticity (LLS) and risk of orchidopexy for cryptorchidism among people with cerebral palsy (CP) and to further define the cremasteric muscle spasticity theory.

METHOD

We queried the Pediatric Health Information System database for male patients with CP, stratified patients into those with/without LLS, and compared groups for orchidopexy occurrence. Comparative statistics were performed using χ2 and Mann-Whitney U tests for categorical and continuous variables respectively. The association between orchidopexy and spasticity type was investigated using logistic regression.

RESULTS

In total, 44 561 males with CP were identified. Of these, 1.6% underwent orchidopexy (median age: 7 years 8 months [interquartile range: 4 years 6 months-11 years 4 months]). LLS presence was significantly associated with higher orchidopexy rate compared to spasticity absence (odds ratio [OR] = 1.33 [1.10-1.59], p = 0.003). Among 7134 patients with LLS, intervention was significantly associated with higher orchidopexy rate (injection procedures: OR = 2.47 [2.27-6.39], p = 0.034; surgical procedure: OR = 2.60 [1.22-6.76], p = 0.026). LLS groin proximity was significantly associated with higher orchidopexy rate (OR = 2.52 [1.42-4.96], p = 0.003).

INTERPRETATION

A strong association exists between LLS presence and severity and orchidopexy risk among people with CP. These findings support a cremasteric spasticity hypothesis as an important factor of cryptorchidism in CP. Providers should continue to examine for cryptorchidism in males with CP as they age.

WHAT THIS PAPER ADDS

Lower limb spasticity (LLS) is associated with higher orchidopexy rate in cerebral palsy. Orchidopexy rate was higher in more severe LLS. Orchidopexy rate was higher in more proximal LLS.

Assessing cancer in people with profound and multiple disabilities

BACKGROUND

Cancers are as common in individuals with intellectual disabilities as in the general population (GP). For the subgroup of people with profound and multiple disabilities (PMD) who present with both severe intellectual disability and major motor disorders, the frequency and distribution of cancers are currently not known, preventing proper cancer surveillance.

METHODS

We carried out a systematic and synthetic review of the medical literature, including a focused search of Japanese data.

RESULTS

The total risk of cancer in individuals with PMD is thought to be lower than in the GP, possibly due to a shorter life expectancy. They have reduced exposure to cancer risk factors, such as alcohol, tobacco, sunlight, human papillomavirus infection, occupational toxins, and being overweight. On the other hand, individuals with PMD present a greater frequency of gastroesophageal reflux disease, Helicobacter pylori gastritis, chronic cystitis, and cryptorchidism, which increase the risk for cancer of the esophagus, stomach, urinary bladder, and testes. In addition, certain genetic disorders underlying compromised motor and cognitive functions are associated with higher risk of childhood cancers. An analysis of 135 cancers in persons with PMD in Japan suggested that they present a particular tumor profile, with certain cancers rarer than in the GP, whereas cancers of the digestive tract are frequent. Cancers of the digestive tract occurred significantly earlier than in the GP (colon: average age 48.3 years vs. 71.3 years in the GP, esophagus: 39 years vs. 72 years in the GP). An increasing number of therapeutic successes in children and adults with PMD have been reported in different countries when cancers are discovered early.

CONCLUSION

Individuals with PMD must be appropriately monitored for cancer. Screenings for breast and colon cancer, as well as regular monitoring of the esophagus, stomach, urinary bladder, and testicles, are necessary. Population-based epidemiological studies are needed to better understand risk factors, frequency, and distribution of cancers in the PMD population.

Abnormal Genetic Testing in Males With Concomitant Neurodevelopmental Disabilities and Genital Malformation

BACKGROUND

Neurodevelopmental disorders (NDDs) affect 1:6 children in the United States and are often linked to genetic disorders. Because many genes are enriched in brain and testicular tissue, genital malformations identified early may be a predictor of genetic disorders in children with NDDs. However, few studies have evaluated the specific effects of genital malformations. This study assesses the association between genital malformations and abnormal genetic testing among male patients with NDD.

METHODS

A retrospective chart review was performed of 447 male patients seen at Children's Health Dallas (2009 to 2019) with concomitant genital malformations and NDDs. We assessed the strength of factors associated with obtaining a genetic test and having abnormal results.

RESULTS

We identified 447 patients with concomitant genital malformations and NDD. Fifty-six percent (251 of 447) received genetic testing, of which 68.5% (172 of 251) had abnormal results. Patients with mixed genitourinary malformations, global developmental delay (GDD), intellectual delay, or autism spectrum disorder were more likely to have a genetic test. Patients with bilateral testicular involvement, GDD, severe language delay, wheelchair dependence, or abnormal magnetic resonance imaging findings were more likely to have abnormal results.

CONCLUSION

The diagnostic yield of 68.5% in our cohort of male patients with genital malformations was higher than previous reports of 5% to 35% in NDD populations. More severe phenotypic features may be associated with increased yield. Identification of genital malformations during infancy may guide clinical surveillance, and copresentations with NDDs may support genetic testing.

Open controversies on the treatment of undescended testis: An update

Cryptorchidism is a common congenital malformation in pediatric urology. Although there have been many studies on the etiology of the disease, it has not been fully clarified, and while its diagnostic and treatment models have gradually approached standardization and systematization, some controversies regarding treatment remain. Additionally, although ultrasound is a non-invasive examination without ionizing radiation, its role in the evaluation of cryptorchidism remains controversial. The main basis for treating cryptorchidism is orchidopexy, and the main view on treatment age is that treatment should be performed between 6 and 12 months after birth, but no more than 18 months after birth. The view on hormone therapy is still controversial because most scholars believe that early surgery is the key to treatment. There are many surgical treatment methods for cryptorchidism, including traditional open surgery and laparoscopic surgery, which provide satisfactory results. In conclusion, the treatment of undescended testis (UDT) had been largely standardized, apart from the treatment of high intra-abdominal testis (IAT), which remains a matter of debate.

Comparison of Laparoscopic Orchiopexy and Traditional Inguinal Incision Orchiopexy for Palpable Undescended Testes in Cryptorchidism

Background: Laparoscopic orchiopexy (LO) has become a standard procedure for the treatment of nonpalpable undescended testes (UDT). LO for palpable UDT is still controversial. The aim of this study is to explore the method and effect of LO procedure for palpable UDT in children suffering from cryptorchidism. Methods: A retrospective study was performed for LO and traditional inguinal incision orchiopexy (TIO) for palpable UDT. A total of 291 children were enrolled, and they were aged 9-96 months with either left- or right-side palpable inguinal canalicular testes. Patients with testes that were nonpalpable, ectopic, and retractable were excluded. One hundred seventy patients received LO and 121 patients received TIO. Patient age, operative time, and clinical outcomes were reviewed. Independent t-test and Fisher's exact test were performed by SPSS 25.0 software. Results: The mean operative time (30.77 ± 6.02 minutes versus 44.76 ± 6.70 minutes) and postoperative normal activity time (1.25 ± 0.43 days versus 2.48 ± 0.68 days) of LO were significantly shorter than those of TIO group (P < .05). Forty-seven of 49 cases (95.9%) aged <1 year successfully achieved LO. Conclusion: LO is an appropriate choice for palpable UDT, especially in younger children aged <2 years. The success rate of LO decreased with age.

Is Testicular Torsion a Real Problem in Pediatric Patients With Cryptorchidism?

Purpose: To present management and outcomes of patients with cryptorchidism suffering from testicular torsion. Methods: This is a retrospective review of pediatric patients with torsion of undescended testes, who were treated between 2009 and 2019. We recorded: the age, symptoms, duration of torsion, results of physical examination, surgery findings, and additional treatment. Additionally, an extensive online literature search, from 2015-2020, was performed to identify other similar case series. Results: We identified 9 boys with torsion of the undescended gonad, which represented 4.7% of all 192 boys with testicular torsion. The mean age of boys with torsion of undescended testis was 8.7 years. The mean duration of symptoms in our study group was long and it was up to 28.5 h. All patients had inguinal canal exploration. In eight cases, testicular necrosis and primary orchidectomy was performed. Furthermore, 45 cases were identified in the literature and reviewed. Conclusion: According to clinical experience and available studies, torsion of male undescended gonads is a comparatively rare condition. Nevertheless, diagnosis is still delayed and connected with inevitable orchidectomy.

Endocrine Dysfunction in Children with Zika-Related Microcephaly Who Were Born during the 2015 Epidemic in the State of Pernambuco, Brazil

Congenital viral infections and the occurrence of septo-optic dysplasia, which is a combination of optic nerve hypoplasia, abnormal formation of structures along the midline of the brain, and pituitary hypofunction, support the biological plausibility of endocrine dysfunction in Zika-related microcephaly. In this case series we ascertained the presence and describe endocrine dysfunction in 30 children with severe Zika-related microcephaly from the MERG Pediatric Cohort, referred for endocrinological evaluation between February and August 2019. Of the 30 children, 97% had severe microcephaly. The average age at the endocrinological consultation was 41 months and 53% were female. The most frequently observed endocrine dysfunctions comprised short stature, hypothyroidism, obesity and variants early puberty. These dysfunctions occurred alone 57% or in combination 43%. We found optic nerve hypoplasia (6/21) and corpus callosum hypoplasia (20/21). Seizure crises were reported in 86% of the children. The most common-and clinically important-endocrine dysfunctions were pubertal dysfunctions, thyroid disease, growth impairment, and obesity. These dysfunctions require careful monitoring and signal the need for endocrinological evaluation in children with Zika-related microcephaly, in order to make early diagnoses and implement appropriate treatment when necessary.

Surgical findings in cryptorchidism in children with Zika-related microcephaly: a case series

Background

Complications in the urinary tract related to congenital Zika syndrome have recently been reported. One complication, cryptorchidism, has been reported by the Microcephaly Epidemic Research Group/MERG, in Pernambuco/Brazil. The present article describes for the first time the surgical findings in a case series of boys with Zika-related microcephaly and cryptorchidism, who underwent surgical testicular exploration as a contribution to better understand the possible mechanisms involved in gonads formation and descent.

Methods

A total of 7 children (11 testicular units), aged 3 to 4 years, were submitted to inguinal or scrotal orchidopexy for the treatment of palpable cryptorchidism between August 2019 and January 2020. Characteristics of the gonads and its annexes related to appendixes, testis-epididymis dissociation, gubernacular insertion, and associated hydroceles and/or hernias were described. Measures in centimetres were taken for volume calculate.

Results

We found a low prevalence of testicular and epididymal appendix (66.7%), a high prevalence of testis-epididymis dissociation (55.6%), low mean testicular volume for their ages (lower for older boys) and ectopic gubernacular insertion in all cases. There was no evidence of associated hydroceles and/or hernias in any case. No surgical complication was registered or reported, and all explored gonads were properly placed in the scrotal sac.

Conclusions

We herein describe the surgical findings of these children's orchidopexies and discuss the possible mechanisms of viral action in embryogenesis and postnatal growth and development of the testes and annexes. These children need to be followed over time due to the higher risk of testicular atrophy and malignancy. Surgical timing seems to be relevant to avoid loss of testicular volume.

Cryptorchidism in Children with Zika-Related Microcephaly

The genitourinary tract was recently identified as a potential site of complications related to the congenital Zika syndrome (CZS). We provide the first report of a series of cryptorchidism cases in 3-year-old children with Zika-related microcephaly who underwent consultations between October 2018 and April 2019 as part of the follow-up of the children cohort of the Microcephaly Epidemic Research Group, Pernambuco, Brazil. Of the 22 males examined, eight (36.4%) presented with cryptorchidism. Among 14 undescended testis cases, 11 (78.6%) could be palpated in the inguinal region. Seven of the eight children had severe microcephaly. Conventional risk factors for cryptorchidism were relatively infrequent in these children. We hypothesize that cryptorchidism is an additional manifestation of CZS present in children with severe microcephaly. As in our cases, for most of the children, the testes were located in the inguinal region, and the possible mechanisms for cryptorchidism were gubernaculum disturbance or cremasteric abnormality.

Optimal Management of Undescended Testis in Boys with Cerebral Palsy. A Debate

Cerebral palsy is a rare condition following injury of the developing brain and including nonprogressive neurological disorders, spasticity, intellectual impairment and others. Boys with cerebral palsy have a high incidence of undescended testis. Although the motives for treatment (infertility, cancer prevention, psychological aspects, testicular torsion) are not different in boys without neurological impairment, the decision-making process in boys with cerebral palsy is very difficult. Besides medical and surgical arguments the discussion involves challenging ethical issues.
