Kellogg ND, Farst KJ, Adams JA. Interpretation of medical findings in suspected child sexual abuse: An update for 2023. CHILD ABUSE & NEGLECT 2023; 145:106283. [PMID: 37734774 DOI: 10.1016/j.chiabu.2023.106283] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 05/12/2023] [Accepted: 06/07/2023] [Indexed: 09/23/2023]
Abstract
Health care professionals who examine children who may have been sexually abused need to be able to recognize, and photo-document any physical signs, and to have access to expert reviewers, particularly when signs concerning for sexual abuse are found. Although the general consensus among practitioners is that children will show few signs of sexual abuse on examination, there is considerable variability and rates of positive exam findings among practitioners of different professions, practice settings, and countries. This review will summarize new data and recommendations regarding the interpretation of medical findings and sexually transmitted infections (STIs); assessment and management of pediatric patients presenting with suspected sexual abuse or assault; and testing and treating patients for STIs. Updates to a table listing an approach to the interpretation of medical findings are presented, and reasons for changes are discussed.

Clinical Differentiation between a Normal Anus, Anterior Anus, Congenital Anal Stenosis, and Perineal Fistula: Definitions and Consequences—The ARM-Net Consortium Consensus. CHILDREN 2022; 9:children9060831. [PMID: 35740768 PMCID: PMC9221870 DOI: 10.3390/children9060831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 05/25/2022] [Accepted: 05/28/2022] [Indexed: 11/16/2022]
Abstract
In the past, an anteriorly located anus was often misdiagnosed and treated as an anorectal malformation (ARM) with a perineal fistula (PF). The paper aims to define the criteria for a normal anus, an anterior anus (AA) as an anatomic variant, and milder types of ARM such as congenital anal stenosis (CAS) and PF. An extensive literature search was performed by a working group of the ARM-Net Consortium concerning the subject “Normal Anus, AA, and mild ARM”. A consensus on definitions, clinical characteristics, diagnostic management, and treatment modalities was established, and a diagnostic algorithm was proposed. The algorithm enables pediatricians, midwives, gynecologists, and surgeons to make a timely correct diagnosis of any abnormally looking anus and initiate further management if needed. Thus, the routine physical inspection of a newborn should include the inspection of the anus and define its position, relation to the external sphincter, and caliber. A correct diagnosis and use of the presented terminology will avoid misclassifications and allow the initiation of correct management. This will provide a reliable comparison of different therapeutic management and outcomes of these patient cohorts in the future.

Abstract
BACKGROUND The simultaneous occurrence of Hirschsprung disease (HD) and anorectal malformation (ARM) is extremely rare, with only a very limited amount of cases published in the literature. Constipation is a major problem in patients operated for ARM, and biopsies from the distal rectum in patients with ARM may not show ganglion cells owing to different reasons, leading to a false positive diagnosis of HD. A pull-through procedure for HD after previous anorectoplasty for ARM always leads to fecal incontinence. The aim of the present study was to assess the incidence of simultaneous diagnoses of ARM and HD in a single large cohort of ARM patients and to demonstrate that biopsies from the anal canal, which are negative for ganglion cells, may mislead to a diagnosis of HD. MATERIALS AND METHODS A retrospective review of our database from 1980 to 2018 identified 164 patients with HD and 2397 patients with ARM. Four patients suffered from both HD and ARM. RESULTS The incidence of HD in ARM patients was 4/2397 = 0.17%, and the incidence of ARM in HD patients was 4/164 = 2.4%. CONCLUSION Our results strongly suggest that the association of ARM and HD is less common than previously reported. TYPE OF STUDY Therapeutic LEVEL OF EVIDENCE: IV.

Abstract
Objective: Currarino syndrome (CS) is characterized by the triad of sacral anomalies, presacral tumor, and anorectal malformation (ARM). This study evaluates the feasibility and outcomes of laparoscopic-assisted anorectal pull-through (LAARP) for CS. Materials and Methods: Children admitted for primary or redo repair of CS through LAARP between 2016 and 2019 were reviewed. The indication of redo included constipation with megarectosigmoid, residual presacral mass, anastomosis leak, and secondary fistula. ARM was corrected by excision of rectal stenosis, fistula, and its associated megarectosigmoid. This was followed by a complete surgical resection of the presacral tumor, with subsequent pull-through and anocolic anastomosis. This was done with a combined laparoscopic and transanal approach. The detailed surgical techniques, early postoperative complications, and mid-term functional outcomes were summarized. Results: Fourteen patients underwent LAARP for primary (N = 4) and redo (N = 10) repair of CS. Four of them had colostomy previously. Mean age at operation was 20.7 ± 13.9 months. Mean operative time was 120 ± 25 minutes. Median hospital stay was 8 days (range 7-9 days) postoperatively. None of the patients developed early postoperative complications such as anastomotic leaks, presacral abscesses, recurrent fistulas, and residual mass. Bowel function was assessed 1 year after LAARP in 10 patients. Mean follow-up time was 15.9 months. The frequency of bowel movements was 3.3 ± 1.5/day. Constipation occurred in 2 patients. Occasional soiling (<3 times/week) was reported in 4 patients and frequent soiling (>3 times/week) was in 1. Conclusion: LAARP for CS is safe and effective.

Abstract
BACKGROUND/PURPOSE Hirschsprung's disease (HSCR) and anorectal malformation (ARM) are often associated with other congenital malformations, but the association of each other is rare. Some studies have reported the incidence of HSCR associated with ARM ranging from 2.0 to 3.4%. The purpose of this study was to update the current epidemiological and therapeutic features of this rare congenital association. METHODS A systematic literature search for relevant articles was performed in four databases using a combination of the following terms "association of Hirschsprung's disease and anorectal malformation", "aganglionosis and anorectal malformation" and "congenital megacolon and anorectal malformation" for studies published between 1952 and 2019. Reference lists were screened for additional cases. RESULTS Forty-three studies met the defined inclusion criteria, reporting a total of 126 patients who were diagnosed with HSCR with ARM. Thirty articles reported 42 single case reports of this association. Twelve articles reported 66 cases of HSCR in case series of 3309 ARM patients, resulting in an incidence of 2% of this association. Associated syndrome was found in 25 cases (20%): Currarino syndrome in 11, Down syndrome in 8, Cat eye syndrome in 4 and Pallister-Hall syndrome in 2 patients. Extent of aganglionosis was reported in 62 cases: short or rectosigmoid aganglionosis was reported in 44, long segment aganglionosis in 8, total colonic aganglionosis in 9 and total intestinal aganglionosis in 1 case. CONCLUSION Although the association of ARM and HSCR is rare, the incidence of HSCR among ARM cases seems to be higher than in the general pediatric population. There was a high incidence of coexistence of ARM and HSCR with severe associated syndromes.

Abstract
Kabuki syndrome (KS) is a rare genetic condition characterized by a distinctive facies, intellectual disability, growth delay, and a variety of skeletal, visceral, and other anomalies, including anorectal malformations (ARMs). We present two cases of female patients with KS, diagnosed and successfully managed at our institution, one with a perineal fistula and one with a rectovestibular fistula. Our report, along with a literature review, shows that the syndrome is usually associated with "low" anomalies, with a potential for a good prognosis. Management of the anorectal anomaly in patients with KS is not essentially different from that in other nonsyndromic patients, taking into account the frequent association of the syndrome with serious congenital heart disease, which might affect the decision-making and timing of the stages of anorectal reconstruction. The frequent occurrence of learning and feeding difficulties makes establishment of toilet training and bowel management rather more challenging, requiring the expertise of a multidisciplinary team. The finding of ARMs in female patients with other characteristics of KS, although inconstant, could support the clinical suspicion for the syndrome until genetic confirmation is available, and should alert the physician for the potential of severe cardiac defects.

Abstract
BACKGROUND The association of Hirschsprung's disease (HD) and anorectal malformation (ARM) is rare. The exact incidence of this association is not known but HD coexisting with ARM has been reported in 2.3 to 3.4% of ARM cases. Most of the reported cases in the literature have been single case reports. The aim of this systematic review was to determine the incidence of HD associated with ARM and its relationship to other syndromes. METHODS A systematic review of the literature was performed for the keywords "association of Hirschsprung's disease and anorectal malformation", "aganglionosis and anorectal malformation" as well as "congenital megacolon and anorectal malformation". Resulting publications were reviewed for epidemiology, operative treatment and morbidity. Reference lists were screened for additional cases. RESULTS A total of 38 articles reported 90 cases of HD coexisting with ARM from 1952 to 2013. Twenty eight articles reported 40 single case reports of this association. Ten articles reported 50 cases of HD in case series of 2,465 ARM patients, resulting in an incidence of 2% of this association. Gender was reported in 63 cases, with 30 males (48%) and 33 females (52%). Associated syndromes were reported in 23 patients: Currarino syndrome in 11, Down syndrome in 8, Cat eye syndrome in 3 and Pallister-Hall syndrome in one case. Extent of aganglionosis was reported in 49 cases and included classical rectosigmoid disease in 36, long segment aganglionosis in 5, total colonic aganglionosis in 7 and total intestinal aganglionosis in one patient. In 35% of the patients stoma was created in the aganglionotic region and failed to work. There was a median delay of 8 months for the diagnosis of HD from initial diagnosis of ARM. Various surgical techniques were employed for the pull-through operation for HD. CONCLUSION The review confirms that the recognition of HD is often delayed because of the initial diagnosis of ARM and the fact that the dysfunctional colostomy is usually proximal to the affected aganglionotic bowel. There is a high incidence of associated syndromes when HD coexists with ARM.

Abstract
Currarino syndrome with Hirschsprung disease (CS-HD) is extremely rare. We present the first family with CS-HD. Case 1: A 28-year-old woman was admitted with severe abdominal distension and dyspnea. She was diagnosed with anal stenosis, hemisacrum, anterior sacral meningocele (ASM), tethered cord (TC), and short-segment aganglionosis. She underwent the modified Duhamel operation after meningocele repair and cord detethering. A bicornuate uterus, bilateral ovarian dermoid cysts, and small rectal duplication were also noted intraoperatively. Case 2: The daughter of case 1 was admitted for abdominal distension and anal stenosis at the age of 17 days. Studies revealed a hemisacrum, ASM, TC, presacral mass, atrial septal defect, polyp in the right nasal cavity, right vesicoureteral reflux, and short-segment aganglionosis. She underwent the modified Soave operation at the age of 1 year and 4 months after meningocele repair, cord detethering, and resection of the presacral mass (epidermoid cyst). In both cases, the aganglionic segments were confirmed by preoperative rectal suction biopsy and postoperative pathological examination on full-thickness rectal specimens. Some causal genes for Currarino syndrome (CS) and Hirschsprung disease (HD) are currently investigated. Thus far, 10 CS-HD cases have been reported, including 6 cases of familial CS. However, all the patients had sporadic HD. Recent reports suggest that anomalies of the enteric nerve system contribute to postoperative constipation in CS cases.

Abstract
Congenital anal web is a rare form of anorectal malformation. In cases of delayed diagnosis, patients can present with signs ranging from mild constipation to complete bowel obstruction. The diagnosis is made by thorough anorectal inspection and a digital rectal exam. We present the case of a 9-month-old boy with Down's syndrome with chronic constipation secondary to an anal web. To our best knowledge, this is the first report of an anal web in a patient with Down's syndrome presenting with severe chronic constipation.

Abstract
PURPOSE To report on a female patient diagnosed with Currarino's triad in adulthood. CASE REPORT This case presents an adult patient with a medical history of a congenital anal atresia, a partial sacral agenesis, and a surgically treated ectopic anus. After a coincidentally observed presacral mass by MRI, due to unexplained constipation later in adulthood, Currarino's triad was suspected in this patient. This triad consists of anorectal malformation(s), sacrococcygeal defects and a presacral mass of various origin. Further investigation confirmed the mass to be a meningocele, and showed a tethered cord and a syrinx. CONCLUSIONS In (young) patients with anorectal malformations, although having no other symptoms, further examination might be required to exclude Currarino's triad. Importance of early diagnosis and multidisciplinary assessment is recommended to establish adequate treatment if needed.

Abstract
BACKGROUND Currarino syndrome (CS) is a triad consisting of partial sacral agenesis, presacral mass, and anorectal malformations, typically anal stenosis but the phenotype varies. The main cause of this monogenic disorder is mutations in the motor neuron and pancreas homeobox 1 gene. We describe the clinical and genetic findings in 4 unrelated Swedish cases with CS and their relatives. METHODS We performed mutation analysis of the motor neuron and pancreas homeobox 1 gene in 4 cases with CS by DNA sequence analysis as well as multiplex ligation-dependent probe amplification. In addition, array comparative genome hybridization was performed in 2 cases. Including relatives, totally, 14 individuals were analyzed. RESULTS We found 2 previously described mutations, 1 de novo nonsense mutation (p.Gln212X) and 1 maternally inherited frameshift mutation (p.Pro18ProfsX38). In the family with the frameshift mutation, we also detected the same maternally inherited mutation in 3 of the proband's 4 brothers, who displayed varying symptoms. All mutation carriers had presacral tumors, although 2 were asymptomatic. CONCLUSION Our findings emphasize the need for genetic counseling and mutation analysis in patients with CS to detect tumors early. It shows the importance of evaluation of the sacrum and the presacral region in patients with anal stenosis with or without funnel anus. Family members of index cases should be considered for evaluation even if they are asymptomatic.

Abstract
Low anorectal malformation comprises about half of all anorectal anomalies. Most of the literature concerning management of anorectal anomalies is centred around the treatment and outcome of high anomalies. The management of low anomalies has been considered significantly less challenging than high anomalies. Also, the outcome of low anomalies has traditionally been considered good. However, recent more critical long-term follow-up reports show a different picture. Many patients with low anomalies suffer from long-term anorectal functional problems, especially constipation but also soiling that occurs in a significant percentage of patients. In this review, we compile the recent views on the diagnosis, surgical treatment and outcome of low anorectal anomalies. We also present an algorithm for the management of these anomalies. The emphasis on the surgical management of low anorectal anomalies is to use as minimally invasive operative methods as possible and preserve the native mechanisms of continence that usually are much better preserved than in more severe high anomalies.
