RESUMEN

Abusive head trauma (AHT) is a significant cause of morbidity and mortality for infants. Determining when to pursue a complete physical abuse evaluation can be difficult, especially for nonspecific findings or when a child appears clinically well. This retrospective study of 7 cases sought to describe the presentation, evaluation, and diagnoses for infants with abnormal subdural collections identified on cranial ultrasound for macrocephaly, and to determine how frequently AHT is diagnosed. The results of this study showed that while each patient presented due to asymptomatic macrocephaly, the extent of the workup varied greatly. In addition, no infants had suspicious injuries for abuse during the initial evaluation or the year following. In summary, among the 7 patients seen for asymptomatic macrocephaly with possible subdural hemorrhage, there were very inconsistent child abuse workups. There needs to be a standardized clinical guideline for this specific patient population involving a child abuse pediatric evaluation.

RESUMEN

A 13-year-old presented with a genital lesion, which helped in guiding a diagnosis of child sexual abuse. The patient disclosed unprotected penile-vaginal penetration by a 20-year-old male neighbor. On exam, her left labia minora had a single 2-cm hypopigmented fleshy non-tender mass, and laboratory studies revealed positive Treponemal IgG IgM antibody (>8) and rapid plasma reagin titer of 1:128, indicating syphilis infection. Given the resolution of the labial mass with treatment of syphilis, this lesion was most consistent with condyloma lata. Genital exams are an important component of pediatric evaluations. Condyloma lata can vary in appearance (papules, nodules, or wart-like lesions) and color and may present as a single lesion or multiple lesions. Our patient had one 2-cm lesion, and therefore, clinicians should assume that an anogenital lesion is condyloma lata in the setting of positive syphilis testing.

RESUMEN

Abusive Head Trauma (AHT) results in more child fatalities than any other form of physical abuse and is associated with significant risk of morbidity for survivors. The diagnosis of AHT is made like any other complex medical condition and is based on a constellation of findings within the context of a reported history provided by the patient's caregiver(s). A standardized process with careful consideration of a differential diagnosis and utilization of a multidisciplinary team is essential. This article explores the history of the diagnosis of AHT, reviews the scientific basis for potential mechanisms, references the recommended medical evaluation, describes common findings, and the importance of early and accurate diagnosis.

RESUMEN

This pilot study explored female caregiver's perception of their child's behaviors during sexual abuse evaluations. We compared reports by caregivers with histories of their own child sexual abuse (PCSA) to caregivers with no prior history of child sexual abuse (NPCSA) regarding their 1) child's sexualized behaviors and (2) perceptions of whether their child had been sexually abused. Forty-four caregivers met inclusion criteria. Ninety-five percent of PCSA caregivers versus 21% of NPCSA caregivers reported at least one behavior from the Child Sexual Behavior Inventory. Our findings identified that PCSA caregivers reported more sexualized behaviors for their children overall, potentially contributing to their perception that their child had been sexually abused. This pilot study demonstrated that caregivers were able to tolerate answering questions about their own history of child abuse. Parents should be asked these questions as this may influence perceptions of their child's behaviors and possible sexual abuse.

RESUMEN

Research has shown that programs utilizing comfort therapy canines in cases of child maltreatment have been successful in providing valuable support to children and their families. To date these programs have made canine comfort therapy dogs available solely within one of the involved disciplines. Therefore, a unique canine comfort therapy program was established specifically to support this pediatric population by implementing a collaborative canine comfort therapy program within two separate disciplines. CALI (Cranston Police, Aubin Center, Leadership in Innovation) was the first official K-9 comfort therapy dog in a police department in Rhode Island (RI), and the first employed dog within the state's only children's hospital. This program provides a longitudinal experience that supports children and their families by fostering a sense of familiarity and trust throughout all the difficult components of a child maltreatment case (e.g., evaluation, treatment, investigation and prosecution).

RESUMEN

Background: Long-term care facilities (LTCFs) including assisted living facilities (ALFs) are hubs for high transmission and poor prognosis of COVID-19 among the residents who are more susceptible due to old age and comorbidities. Aim: Houston Health Department conducted assessments of ALFs within the City of Houston to determine preparedness and existing preventive measures at the facilities. Methods: Onsite assessments were conducted at ALFs using a modified CDC Infection Control Assessment and Response (ICAR) Tool. Data was obtained on IPC measures, training, testing, vaccination etc. Data was analyzed, frequencies generated, and bivariate associations determined. Results: A total of 118 facilities were assessed and categorized into small scale 46 (39%), medium scale 47 (40%), and large scale 25 (21%). The facilities had 2431 residents and 2290 staff. Thirty-one (26%) facilities reported an outbreak in 2020, while 14 (12%) had an ongoing outbreak. Twenty-three (97%) large-scale and 12 (26%) small-scale facilities had COVID-19 testing program. Vaccination coverage among residents ranged from 99% in large-scale to 40% in small-scale facilities but was smaller among staff at 748 (45%) in large scale, 71 (36%) in small scale, and 193 (45%) in medium scale. While 24 (96%) large-scale and 34 (77%) of small-scale facilities conducted staff training staff on IPC practices, 22 (92%) of large-scale and 19 (56%) of small-scale facility staff demonstrated capacity (p = 0.01), respectively. Visitor screening was done at 100% of large-scale and 80% of small-scale and the medium-scale ALFs. Discussion: Assisted living facilities within the city of Houston are at various levels of preparedness and interventions with respect to COVID-19 response.

RESUMEN

OBJECTIVE: Division of the sternothyroid muscle during thyroidectomy is a widely accepted surgical technique to provide improved exposure of the thyroid gland, thus facilitating the ligation of superior pole vessels and identification of the laryngeal nerves. However, few have examined the impact on voice outcomes. We evaluate the impact of sternothyroid muscle division on patient-perceived voice outcomes after thyroidectomy. STUDY DESIGN: Prospective cohort study. SETTING: Tertiary academic institution. METHODS: A prospective cohort study was conducted comparing pre- and postoperative voice outcome data after thyroidectomy, measured using Voice Handicap Index-10. The cohort of 109 patients underwent lobectomy or total thyroidectomy by a single surgeon at 1 institution. The sternothyroid muscle was fully divided in all surgeries. The integrity of the recurrent laryngeal and external branches of the superior laryngeal nerve was assessed using intraoperative nerve monitoring and postoperative laryngoscopy. Pre- and postoperative Voice Handicap Index-10 scores were compared. RESULTS: No statistically significant difference was found between total pre- and postoperative Voice Handicap Index-10 scores (µpreop = 1.92, µpostop = 1.83, p = .87). There were no questions yielding statistically significant responses between pre- and postoperative groups. This was consistent regardless of whether the sternothyroid muscle was cut unilaterally or bilaterally. Men showed a statistically significant improvement in score after surgery. CONCLUSION: These findings support no difference in postoperative voice outcomes after the intraoperative division of the sternothyroid muscle. This supports the usage of this technique as a safe means to facilitate exposure during thyroid surgery and will serve as important information to guide intraoperative surgical decision-making.

RESUMEN

Background: Human papillomavirus associated oropharyngeal squamous cell carcinoma (HPVOPSCC) usually affects a younger patient population. As such, the risk for long term toxicity associated with therapy is an important consideration. Multiple trials focused on de-escalation of therapy to preserve survival outcomes while minimizing treatment toxicity are currently in progress, however the question of which patients are ideal candidates for de-escalation remains unanswered. Circulating tumor DNA (cfHPVDNA) has emerged as a means of monitoring disease in patients with HPVOPSCC. Undetectable postoperative cfHPVDNA levels portend a better prognosis and by extension, may identify ideal candidates for de-escalation therapy. We propose an overview and rationale for a new institutional clinical trial protocol focusing on the use of cfHPVDNA to risk stratify patients for adjuvant therapy. We hypothesize that many surgical patients currently receiving radiation therapy may be clinically observed without adjuvant therapy. Methods: Patients with measurable cfHPVDNA and clinically resectable HPVOPSCC will undergo TORS resection of tumors and neck dissection. Patients with undetectable cfHPVDNA at 3 weeks post-op will be allocated to low or high-risk treatment protocol groups. The low risk group consists of patients with <4 positive lymph nodes, ≤2 mm extranodal extension (ENE), and perineural invasion (PNI) or lymphovascular invasion (LVI) alone. The high-risk group is made up of patients with ≥4 positive lymph nodes, gross ENE, positive margins, N2c disease and/or the combination of both PNI and LVI. The low-risk group will be allocated to an observation arm, while the high-risk group will receive 46 Gy of adjuvant radiotherapy and weekly cisplatin therapy. The primary outcome of interest is 2-year disease recurrence with secondary outcomes of 2-year disease free survival, locoregional control, overall survival, and quality of life measures. A sample of 126 patients in the low-risk group and 73 patients in the high-risk group will be required to evaluate non-inferiority to the standard of care. Discussion: This study will provide much needed recurrence and survival data for patients that undergo primary TORS followed by observation or de-escalated adjuvant therapy. Additionally, it will help delineate the role of cfHPVDNA in the risk stratification of patients that undergo treatment de-intensification.

RESUMEN

A 9-year-old male with history of mixed hearing loss presented with petrous apex lesion following episode of meningitis. Serial imaging revealed persistence of the lesion necessitating biopsy to rule out malignancy. Biopsy revealed inflammatory changes. The management of petrous apex lesions following meningitis can be conservative but repeat imaging is necessary to rule out progression and to rule out neoplastic process.

RESUMEN

Dual training in Internal Medicine-Pediatrics (MedPeds) was recognized by the American Board of Medical Specialties in 1967. Residents complete 24 months each in Internal Medicine and Pediatrics and are board-eligible for both at the conclusion of training. Graduates are eligible for fellowships in either or both fields. Many graduates pursue fellowship training. A small absolute number of graduates apply for dual training in adult and pediatric subspecialties, but those that do bring direct, in-depth clinical experience across the lifespan, and familiarity with care in both pediatric and adult settings. As such, they contribute unique perspectives and capabilities to their fellowship and future practice. This includes the ability to provide subspecialty care in settings with limited resources, where they are able to address needs without age restrictions, and in the transition of subspecialty care for emerging adults with childhood-onset conditions. Due to the small number of applicants pursuing joint adult and pediatric fellowships, many fellowship directors may have limited experience with dual fellowships but may want to create opportunities for these unique trainees. This summary was developed jointly by residents, fellows, MedPeds program directors, and fellowship directors in Pediatrics and Internal Medicine subspecialties, and approved by their respective leadership councils to offer some key points on common questions, suggest additional resources, and share best practices, with a goal of facilitating this process for fellowship programs and residents alike.

RESUMEN

Males, in particular adolescents and young adults, have been increasingly recognized as involved in domestic minor sex trafficking (DMST). However, there are very sparse resources and organizations that provide prevention, identification, and interventions for boys and young men who are involved in or at-risk for DMST involvement. The objective was to develop and assess an educational curriculum to prevent adolescent male involvement in DMST through a three-pronged educational approach: as victims of sexual exploitation; receiving financial benefit as exploiters; as buyers of sex. Through quality improvement cycles, changes were made to enhance the curriculum by utilizing the outcome measures of participant questionnaires and feedback from a steering committee of clinical experts. Male youth at the state's juvenile detention center were asked to participate in pilot groups, as they were identified as a high-risk population of adolescents to become involved. The curriculum was modified by adding sessions, including additional community guest speakers, and providing a more holistic educational experience that involves trafficking prevention from both a victimization and perpetration standpoint. Our goal is to expand this educational opportunity to be utilized in multiple settings (e.g., schools, hospitals) across the country.

RESUMEN

OBJECTIVE: Close medical follow-up after pediatric acute sexual assault is recommended and may mitigate adverse consequences and decrease long-term comorbidities. The objectives are to (1) examine adherence to a comprehensive outpatient medical follow-up protocol after evaluation in the emergency department in a pediatric population and (2) identify characteristics associated with patient adherence to inform the utilization of a medical follow-up protocol after pediatric acute sexual assault. METHODS: A retrospective medical record review was conducted of patients younger than 18 years presenting to the emergency department from January 1, 2010, to December 31, 2013, with a discharge diagnosis suggestive of sexual assault/abuse. We examined differences in demographics, assault characteristics, and medical/legal needs of patients who were evaluated in follow-up versus patients who were not. RESULTS: Of 182 patients, 60.4% completed follow-up appointments with the child protection center. Younger patients had follow-up rates higher than older patients (70.2% vs 50%; odds ratio [OR], 0.42). For patients where child protective services or law enforcement were called, follow-up rates were 74.2% and 64.7%, respectively (OR, 2.5; OR, 3.1). All patients with anogenital injuries on initial examination were seen in follow-up. The majority of patients who followed-up were accompanied by a caregiver/relative (95%). CONCLUSIONS: (1) Caregivers should be integrated into the evaluation to facilitate compliance with follow-up; (2) child abuse specialists may be consulted to facilitate specific interventions and recommendations; (3) professionals should work as a multidisciplinary team; and (4) the patient's psychological status should be evaluated, and mental health interventions recommended.

RESUMEN

Domestic minor sex trafficking (DMST) is the commercial sexual exploitation of children (<18 years old) who are U.S. citizens or lawful permanent residents, victimized within U.S. borders. There is limited knowledge and research in regard to male involvement in DMST outside the context of homelessness and runaway youth. To our knowledge, no research specifically examines at-risk or involved male youth from a larger dataset of youth who present to a child abuse outpatient medical clinic. The objective of the present case series was to describe the demographic, psychosocial, medical, and psychiatric characteristics of natal male participants (who did not identify as transgender) suspected of DMST involvement. Six medical records of male patients under the age of 18 who were referred to a child protection clinic for concern of DMST involvement between 8/1/13 and 12/31/18 were retrospectively reviewed. Our case series demonstrates that male participants present for concern of sex trafficking and have complex behavioral, medical, and psychiatric concerns similar to what has been identified in research focused on female victims. Therefore, testing (e.g., sexually transmitted infection (STI)/HIV testing, urine toxicology screening), DMST screening, and interventions (e.g., STI prophylaxis, referrals to mental health counselors) should be completed in male patients.

RESUMEN

ABSTRACT: Substance use and abuse have been documented as both a risk factor in and consequence of involvement in domestic minor sex trafficking (DMST). Domestic minor sex trafficking is defined as the commercial sexual exploitation of children in exchange for money, food, shelter, or any other valued entity. The current investigation sought to describe substance use in a cohort of DMST patients who present for medical evaluation. Findings revealed that 68 patients referred for DMST involvement reported high rates of alcohol/substance use and parental substance abuse. Further, many patients who had a urine toxicology screen had a positive result, most often identifying the presence of cannabinoids. Our data may inform the importance of comprehensive assessments and specialized interventions for substance abuse in this unique patient population.

RESUMEN

OBJECTIVES: Otitis media with effusion (OME) is a common disease of childhood that is largely asymptomatic. However, middle ear fluid can persist for months and negatively impact a child's quality of life. Many cases of OME remain chronic and require surgical intervention. Because biofilms are known to contribute to the persistence of many diseases, this study examined effusions collected from children with chronic OME for the presence of essential biofilm structural components, members of the DNABII family of bacterial DNA-binding proteins. METHODS: Middle ear effusions were recovered from 38 children with chronic OME at the time of tympanostomy tube insertion. A portion of each specimen was submitted for microbiology culture. The remaining material was assessed by immunoblot to quantitate individual DNABII proteins, integration host factor (IHF), and histone-like protein (HU). RESULTS: Sixty-five percent of effusions (24 of 37) were culture-positive for bacterial species or yeast, whereas 35% (13 of 37) were culture-negative. IHF was detected in 95% (36 of 38) at concentrations from 2 to 481 ng/µL effusion. HU was detected in 95% (36 of 38) and quantitated from 13 to 5,264 ng/µL effusion (P ≤ 0.05 compared to IHF). CONCLUSION: Because DNABII proteins are essential structural components of bacterial biofilms, these data lend further support to our understanding that biofilms are present in the vast majority of chronic middle ear effusions, despite negative culture results. The presence and ubiquity of DNABII proteins in OME specimens indicated that these proteins can serve as an important clinical target for our novel DNABII-directed strategy to treat biofilm diseases such as chronic OME.

RESUMEN

Domestic minor sex trafficking (DMST) is an increasingly recognized traumatic crime premised upon the control, abuse, and exploitation of youth. By definition, DMST is the "recruitment, harboring, transportation, provision, or obtaining of a person for the purpose of a commercial sex act" within domestic borders, in which the person is a U.S. citizen or lawful permanent resident under the age of 18 years. The present study described the demographics, psychosocial features, and trafficking experiences (e.g., environments of recruitment, relationship to trafficker, solicitation) of DMST victims. A total of 25 medical records of patients under the age of 18 who disclosed their involvement in DMST to medical providers between August 1, 2013, and November 30, 2015, were retrospectively reviewed. The majority of patients were female, and the mean age was 15.4 years old. Most patients lived at home and/or were accompanied at the evaluation by a parent/guardian. High rates of alcohol or substance use/abuse (92%), being placed in a group home or child protective services (CPS) custody (28%), a history of runaway behavior (60%), and/or exposure to other child maltreatment (88%) were identified. Our data indicated variation in reported trafficking experiences; however, patients commonly reported an established relationship with their trafficker (60%) and recruitment occurred primarily as a result of financial motivation (52%). Patients were prevalently recruited in settings where there were face-to-face interactions (56%), whereas the solicitation of sex-buyers occurred primarily online (92%). Victims who disclosed involvement in DMST had complicated psychosocial histories that may have rendered them susceptible to their exploitation, and reported a variety of DMST experiences perpetuated by traffickers. Although preliminary in nature, this study provided empirical evidence of the predisposing factors, motivations, and experiences of victimized youth uniquely from the perspective of patients who sought medical care.

RESUMEN

OBJECTIVES: To evaluate the impact of allograft and xenograft in pediatric tympanoplasty on patient outcomes. METHODS: A retrospective cohort study of 50 pediatric patients undergoing tympanoplasty at a single tertiary pediatric hospital system that received either autograft, allograft, or xenograft. Patients were evaluated for persistent perforation, recurrent perforation, revision surgery, and postoperative infection. Hearing outcomes, operative charges, and operative time were also evaluated. Statistical analyses included chi-square and Fisher exact tests for categorical data and Wilcoxon-Mann-Whitney tests for continuous data. RESULTS: Half of the cohort received autografts, whereas 38% received xenografts and 14% received allografts. Although there was not a significant difference in charges associated with these procedures, xenografts had the shortest mean operative time (mean: 39 vs 68 minutes in autografts, p = .05). Overall, the rate of persistent perforation was 10%, recurrent perforation was 20%, revision surgery was 16%, and postoperative infection was 18%. There were no differences in the rates of these outcomes by graft type. Furthermore, there was no observed difference in hearing outcomes among autograft and xenograft recipients, but allograft recipients had significantly improved hearing postoperatively. CONCLUSIONS: Similar rates of complications were observed among autografts, xenografts, and allografts, providing preliminary evidence that they are safe to use in pediatric tympanoplasty.
