Evaluation of the level of information of pediatricians about the diagnosis and management of cryptorchidism.

OBJECTIVE: Evaluate the level of information of pediatricians about the diagnosis and management of cryptorchidism. METHOD: A cross-sectional observational study was conducted using a form via the "Google Forms" platform. The study population included pediatricians and pediatric residents associated with the Brazilian Society of Pediatrics. Seven hundred twenty-eight responses were recorded and analyzed using IBM SPSS v21. RESULTS: 728 valid responses were obtained. Of these answers, only 20.5 % answered that the physical examination was sufficient for the diagnosis, and 79.4 % responded that they requested ultrasound as the best test to aid in diagnosing cryptorchidism. When questioned about the ideal age for referring a patient with cryptorchidism, the survey recorded 56.3 % of the responses defending the correct age as six months old, 30.2 % shortly after birth, and 13.2 % at two years old. Other topics were addressed in the form, such as the frequency of evaluation of testicular position and investigation for DDS, among others. Still, the answers to these questions were compatible with current manuals and guidelines on cryptorchidism. CONCLUSION: It is evident that the understanding of the professionals consulted about the diagnosis and management of cryptorchidism needs to be updated with the current practices adopted and that pediatricians, in general, must maintain periodic programs on this subject. Therefore, this topic should be part of a continuing education program with pediatric surgery.

The undescended testis in children and adolescents part 2: evaluation and therapeutic approach.

Undescended testis (UDT) is defined as failure of a testis to descend into the scrotum and it is a common reason for consultation in pediatric urology. As extensively discussed in "The undescended testis in children and adolescents: part 1", the failure of a testis to descend alters testicular germ-cells development, increasing the risk of infertility and testicular cancer in adulthood. Here, we present the second part of our review and analysis of this topic with the aim to propose an updated and well-informed approach to UDT together with a treatment flow chart that may be useful to guide pediatric surgeons and urologists in the care of these patients. The main goal of the management of patients with UDT is to diminish the risk of infertility and tumor development and is based on the clinical findings at the time of diagnosis.

Imperícia no diagnóstico de criptorquidismo bilateral em felino / Malpractice in diagnose bilateral feline cryptorchidism

O objetivo deste relato é descrever um caso de imperícia no diagnóstico de criptorquidismo inguinal bilateral em um gato. Foi atendido um gato em um Hospital Veterinário Universitário para castração eletiva. O tutor declarou ser uma fêmea. Foi realizado exame de sangue e ultrassonografia (US) para descarte de gestação. O animal foi encaminhado para ovariohisterectomia (OH) de rotina. No entanto, não foi possível localizar os ovários e o útero e a laparotomia foi encerrada. No pós-operatório imediato examinou-se novamente a genitália externa. Neste exame, o pênis foi localizado, mas não foram detectados os testículos. O animal foi liberado e trinta dias depois retornou para nova consulta. Nesta ocasião, realizou-se exame físico minucioso e exame ultrassonográfico da região inguinal, constatando-se que o animal apresentava criptorquidismo inguinal. Muitas vezes o criptorquidismo nos gatos é diagnosticado durante o exame físico, mas a US é útil no diagnóstico de criptorquidismo. O animal foi submetido à orquiectomia e, durante o procedimento cirúrgico, foram localizados os dois testículos, caracterizando criptorquidismo inguinal bilateral. Embora os testículos ectópicos na região inguinal possam estar cobertos por uma placa de gordura, dificultando a palpação, o pênis do gato pode ser visto através de simples exposição manual. Provavelmente tal manobra não foi realizada na primeira consulta, o que levou a um erro na identificação do sexo. Concluiu-se que a avaliação detalhada no exame físico é de fundamental importância em qualquer procedimento cirúrgico.

The aim of this paper is to describe a case of malpractice in the diagnosis of bilateral inguinal cryptorchidism in a cat. A cat was attended at the Teachdfring Veterinary Hospital. The owner requested elective spaying. The owner declared it to be a female. Blood tests and ultrasound were performed to discard pregnancy. The animal was referred for routine ovariohysterectomy (OH). However, it was not possible to locate the ovaries and uterus and the laparotomy was finished. In the immediate postoperative period, the external genitalia was examined again. In this examination, the penis was located, but the testicles were not detected. The animal was released and thirty days later returned for further consultation. On this occasion, a thorough physical examination and ultrasound examination of the inguinal region were performed. In this exam it was verified that the animal presented inguinal cryptorchidism. Cryptorchidism in cats is often diagnosed during physical examination, but ultrasound (US) is useful in diagnosing cryptorchidism. The animal was submitted to orchiectomy and, during the surgical procedure, both testicles were located, characterizing bilateral inguinal cryptorchidism. Although the ectopic testicles in the inguinal region may be covered by a fatty plaque, making palpation difficult, the cat's penis can be seen through simple manual exposure. Probably such a maneuver was not performed in the first consultation, which led to an error in the identification of sex. It was concluded that the detailed evaluation in the physical exam is of fundamental importance in any surgical procedure.

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 free-living jaguar (Panthera onca): first case report

Cryptorchidism is a genital alteration wherein one or both testicles fail to descend into the scrotum and has multifactorial causes. A free-range adult male was captured twice in the Pantanal of Nhecolândia to put a GPS collar and semen collection. Pharmacological semen collection, andrological examination and semen analysis were performed. At the first capture and during the andrological examination only the left testis was found, and the male qualified as cryptorchid. The penis had no penile spines at either procedure. The semen volume obtained at first and second capture was 435 and 160 L, respectively, with a concentration of 618 and 100 x 106 sperm/mL, progressive motility of ~ 5% and ~ 1% and total morphological sperm abnormalities of 74% and 86%. The male was monitored by a GPS collar, but the signal was lost, making it difficult to re-captures and perform new seminal and ultrasound evaluations to discard monorchidism exceedingly rare in felids. Genetic studies to assess the individual's homozygosity are necessary to verify whether cryptorchidism in this individual has a genetic factor.

Evaluation and Management of the Undescended Testis in Puerto Rico: A Single Surgeon's 10 Years of Experience.

OBJECTIVE: Cryptorchidism is an abnormality of the male genitourinary tract in which one or both testes fail to descend into the scrotum. The American Urological Association (AUA) clinical guidelines for the evaluation and treatment of cryptorchidism were recently published. We reviewed our experience with the evaluation and management of our patients and examined our findings with respect to the AUA and European Association of Urology (EAU) guidelines. METHODS: Data were obtained from pediatric patients who underwent a surgical intervention for an undescended testis from 2007 through 2017 at HIMA Hospital and the University Pediatric Hospital (both in Puerto Rico); all the surgeries were performed by the same surgeon. A total of 754 patients were identified; 142 patients were excluded due to lack of follow-up data (N = 612). The data obtained included age, testes locations, radiologic and surgical findings, and postoperative results. RESULTS: At their initial evaluations, a large proportion of the patients (46.4%) came accompanied with radiographic imaging. These findings were consistent with those of the physical examination in 58.5% of the patients and with the surgical findings in 63.1% (sensitivity 77.9%, specificity 45.8%). Our data showed that the median referral age was 24 months, which suggests that there was a significant delay in diagnosis. At the time of surgery, the average age of the patients who required an orchiectomy was 3.93 years, while those who underwent an orchiopexy had an average age of 3.28 years. CONCLUSION: Our data reveal that, despite its lack of usefulness, radiologic imaging continues to be included in the diagnostic workups of children newly identified with cryptorchidism in Puerto Rico. In addition, and contrary to the guidelines, there tends to be a significant delay in treatment with surgical intervention. It is important to continue to educate our referring physicians on the AUA and EUA guidelines in order to create awareness and encourage the proper diagnostic and treatment approach for cryptorchidism.

Anogenital distance and reproductive outcomes in 9- to 11-year-old boys: the INMA-Granada cohort study.

BACKGROUND: Studies examining the association of anogenital distance (AGD), a biomarker of prenatal androgen exposure, with sexual development in children are lacking. OBJECTIVE: To assess the association between AGD measures and reproductive outcomes, including puberty onset, testicular volume, reproductive hormone levels, and urogenital malformations in boys aged 9-11 years. MATERIALS AND METHODS: A cross-sectional study was conducted among children belonging to the Spanish Environment and Childhood (INMA) Project, a population-based birth cohort study. The present sample included 279 boys for whom data were available on AGD, pubertal stage, testicular volume, and relevant covariates. Out of the boys with AGD data, 187 provided a blood sample for hormone analysis. AGD was measured from the center of the anus to the base of the scrotum. Pubertal development was assessed according to Tanner stage of genital development (G1-G5), and testicular volume was measured with an orchidometer. RESULTS: After adjusting for potential confounders, logistic regression analysis showed that AGD was positively associated with testicular volume but not with Tanner stage (>G1 vs. G1), serum hormone levels, or undescended testis. Regardless of their age, body mass index, and Tanner stage (G1 or >G1), boys with longer AGD showed increased odds of a testicular volume >3 mL (OR = 1.06, 95%CI = 1.00-1.19 per 10% increment in AGD; and OR = 3.14, 95%CI = 0.99-9.94 for AGD >42 mm vs. <33 mm). DISCUSSION: Longer AGD was associated with testicular growth, an indicator of gonadarche, but not with other reproductive outcomes. CONCLUSIONS: Although AGD was positively associated with testicular volume, it remains unclear whether AGD predicts testis size at puberty or is related to puberty onset.

Health Disparities in the Appropriate Management of Cryptorchidism.

OBJECTIVE: To assess regional practices in management of cryptorchidism with regard to timely fixation by the current recommended age of 18 months. STUDY DESIGN: A retrospective study was performed. Charts of all patients who underwent surgical correction for cryptorchidism by a pediatric general surgeon or urologist within a tertiary pediatric hospital in an urban setting were systematically reviewed. RESULTS: We identified 1209 patients with cryptorchidism. The median age of surgical correction was 3.7 years (IQR: 1.4, 7.7); only 27% of patients had surgical correction before 18 months of age. Forty-six percent of our patients were white, 40% were African American, and 8% were Hispanic. African American and Hispanic patients were less likely to undergo timely repair (P?=?.01), as were those with public or no insurance (P?

Ocorrência de patologias em machos felinos atendidos no Hospital Veterinário da Universidade Federal Rural da Amazônia / Occurrence of diseases in cats males treated at the Veterinary Hospital of the Federal Rural University of Amazonia

The pathologies of the reproductive system of cats are common in veterinary medicine and are alwayscomplex and multifactorial, where the primary objective is to determine the cause of the problem, both infemales as in males, with varying degrees of morbidity, mortality and suffering influences reproductive historyfrom previous pharmacological treatments and environmental conditions and can therefore be regionalvariations in the incidence of certain reproductive abnormalities. Cryptorchidism is incomplete testiculardescent, may be retained in any follow this path. The survey was conducted at the Veterinary Hospital (HOVET /UFRA), Belém / Pará, with animals attended by residents of Animal Reproduction Section, feline fromBethlehem. The information on the animals were obtained by consulting the records contained in the files theSISVET (veterinary System) program being evaluated only attended by veterinary medical residents of the Sectorof Small Animal Reproduction Clinic of this hospital.

Sertolioma associado à seminoma em cão com criptorquidismo bilateral - relato de caso / Sertoli cell tumor to seminoma in dog with unilateral cryptorchidism - case report

This work aims to report the occurrence of a mixed testicular neoplasm, seminoma associated withsertolioma, in the ectopic testis located in the left inguinal canal of a dog. A 9-year-old male poodle dog wastreated at the Small Animal Clinic of the Veterinary Hospital of the State University of Maranhão (HVU-Uema),presenting thrombocytopenic haemorrhagic purpura and swelling of firm contents in the left inguinal region,with pain on palpation of the area. In the cytology analysis it was observed high cellularity composed by twodistinct cell types. Thus, according to the clinical and cytopathological findings, it was diagnosed Semenomaassociated with Sertolioma. It is an important finding, since the method of diagnosis by cytology is not verysensitive in the joint detection of these two neoplasms.

Agenesia renal unilateral e criptorquidismo ipsilateral em um felino: relato de caso / Unilateral renal agenesis and ipsilateral cryptorchidism in a cat: case report

A agenesia renal é uma afecção congênita rara na espécie felina, frequentemente associada a uma malformação reprodutiva. O presente trabalho relata o caso de um felino com agenesia renal unilateral associada a criptorquidismo ipsilateral, com ênfase no diagnóstico, tratamento e acompanhamento. O paciente foi conduzido ao Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul para avaliação de criptorquidismo. A agenesia renal foi um achado durante a ecografia abdominal do felino. Durante a laparotomia, foi confirmada a ausência do rim e ureter direito, hipertrofia do rim esquerdo e presença de um testículo ectópico. O paciente teve alta após a recuperação anestésica e se mantém clinicamente estável, transcorridos seis meses da cirurgia. A agenesia renal unilateral é uma condição compatível com a vida, contanto que o rim existente apresente funcionamento aceitável. Assim, sugere-se que a possibilidade de rim único em felinos criptorquidas deve ser investigada sempre que possível, tendo em vista a alta correlação entre essas malformações, e objetivando um acompanhamento da função renal do paciente ao longo da vida.(AU)

Renal agenesis is a rare disorder in feline species, commonly associated with reproductive malformation. This study aims to report the case of a cat with unilateral renal agenesis combined with ipsilateral cryptorchidism, emphasizing the diagnosis, treatment and patient follow up. The patient was taken to the Veterinary Hospital of the Federal University of Rio Grande do Sul to evaluate the cryptorchidism. The renal agenesis was an incidental finding during the abdominal ultrasound. At laparotomy, the absence of the right kidney and ureter was confirmed, hypertrophy of the left kidney and the presence of an ectopic testicle were found. The patient was discharged after recovering from anesthesia and remains clinically stable six months after surgery. The unilateral renal agenesis is a life compatible condition as long as the existing kidney has an acceptable performance. Therefore, it is suggested that the chance of a single kidney in cats whit cryptorchidism should be investigated, given the correlation between these malformations, and aiming to monitor renal function throughout the life of the patient.(AU)
