Evaluation of Two Videos that Apply Evidence-Based Strategies to Increase Self-Efficacy and Reduce Opioid-Related Stigma Among Medical Students.

OBJECTIVE: This study evaluated the video-based application of evidence-based stigma reduction strategies to increase medical students' screening-diagnostic self-efficacy for opioid use disorder (OUD) and reduce stigma toward opioid use. METHODS: Formative qualitative research informed development of two videos for medical students. One uses an education strategy by including education regarding non-stigmatizing language use and OUD screening and diagnosis (Video A); the other uses an interpersonal contact strategy by presenting narratives regarding opioid use from three people who have a history of opioid use and three physicians (Video B). Both videos were administered to all respondents, with video order randomized. Effects on outcomes were evaluated using a pre-/post-test design with a 1-month follow-up. Participants also provided feedback on video content and design. RESULTS: Medical students (N = 103) watched the videos and completed the pre-/post-test, with 99% (N = 102) completing follow-up 1 month after viewing both videos. Self-efficacy increased directly following viewing Video A, and this increase was sustained at 1-month follow-up. Stigma toward opioid use decreased directly following viewing Video B, and this decrease was sustained at 1-month follow-up for participants who watched Video B first. Statistically significant improvements were observed in most secondary outcomes (e.g., harm reduction acceptability) directly following watching each video and most were sustained at 1-month follow-up. Feedback about the videos suggested the delivery of evidence-based strategies in each video was appropriate. CONCLUSIONS: Video-based applications of these evidence-based strategies were found acceptable by medical students and have potential to elicit sustained improvement in their screening-diagnostic self-efficacy and opioid-related stigma.

Müllerian anomalies in girls with congenital solitary kidney.

BACKGROUND: The prevalence of Müllerian anomalies (MA) among patients with congenital solitary functioning kidney (SFK) is not well defined. A delay in diagnosis of obstructive MA can increase the risk of poor clinical outcomes. This study describes the prevalence of MA in patients with congenital SFK. METHODS: A retrospective review was performed of patients within the Nationwide Children's Hospital system with ICD9 or ICD10 diagnostic codes for congenital SFK defined as either unilateral renal agenesis (URA) or multicystic dysplastic kidney (MCDK) and confirmed by chart review. Patients with complex urogenital pathology were excluded. Renal anomaly, MA, reason for and type of pelvic evaluation, and age of diagnosis of anomalies were evaluated. RESULTS: Congenital SFK occurred in 431 girls due to URA (209) or MCDK (222). Pelvic evaluation, most commonly by ultrasound for evaluation of abdominal pain or dysmenorrhea, occurred in 115 patients leading to MA diagnosis in 60 instances. Among 221 patients ages 10 years and older, 104 underwent pelvic evaluation and 52 were diagnosed with an MA of which 20 were obstructive. Isolated uterine or combined uterine and vaginal anomalies were the most common MA. MA were five-fold more common in patients with URA compared to MCDK. In 75% of patients, the SFK was diagnosed prior to the MA. CONCLUSIONS: The prevalence of MA in patients with congenital SFK was 24% among those age 10 years or older, and 38% were obstructive. This justifies routine screening pelvic ultrasound in girls with congenital SFK to improve early diagnosis.

Young Men's Attitudes and Understanding of Menstruation.

PURPOSE: To identify sources of information, perceptions, and potential misinformation about menstruation among college-aged men in the United States. METHODS: This is a mixed-methods cross-sectional survey study of students in the United States. Inclusion criteria included participants aged 17-29 years, male gender identity, enrolled as an undergraduate or graduate student, and no personal history of menstruation. RESULTS: This study included 70 participants. Almost half of all participants (42.9%) first learned about menstruation from family members. More than two-thirds of respondents felt that menstrual education was essential or very important for all genders. The most common symptoms noted to be associated with periods included cramping (93.6%), mood changes (80.9%), and vague "hormonal" changes (36.2%). When asked how a menstrual period might affect someone's ability to perform daily activities, one-third reported debilitating or very burdensome symptoms, whereas one-fifth felt periods do not have much impact. DISCUSSION: Comprehensive education and accurate reproductive health knowledge are critical in combating gender bias and stigma. Most males surveyed agree that education on menstruation is important, yet the majority do not have or do not remember formal education on this topic, instead relying on family members and friends as learning tools and resources. Most participants identified negative symptoms associated with menstrual periods, especially mental health concerns including mood changes and irritability. This association with mood changes, as well as vague "hormonal fluctuations," contributes to the societal bias against people who menstruate by marking them as prone to emotional instability, thereby exacerbating gender prejudices. It is therefore critical that accurate menstrual education be widely available for everyone, regardless of gender.

[Recommendations for the diagnosis and treatment of IgG4-related disease in China].

IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition characterized by tumefactive lesions in multi-organs. It is a novel entity presented by variable manifestations. In recent years, there has been progress toward recognizing IgG4-RD. However, the diagnosis and treatment of IgG4-RD still present challenges due to insufficient experience. To address this, the Chinese Rheumatology Association has developed standardized guidelines for the diagnosis and treatment of IgG4-RD based on domestic and international experience. These guidelines aim to enhance the understanding and management of IgG4-RD, ultimately improving the prognosis for patients with IgG4-RD.

[Effects of RNA M6A demethylase ALKBH5 gene deficiency on morphology and function of cerebellum in aged mice].

Objective: To investigate the effects of RNA m6A demethylase ALKBH5 gene deficiency on cerebellar morphology and function in the aged mice, and to explore the role of ALKBH5 in cerebellar degeneration. Methods: Western blot was performed to detect the protein level of ALKBH5 in the cerebellum of wild-type mice of various ages. The expression of NeuN, Calbindin-D28K, MAP2, GFAP and other proteins in the cerebella of middle-aged (12-month-old) and aged (18-month-old) wild-type mice and ALKBH5-/- mice was examined using immunohistochemistry. The balance beam test and gait analysis were performed to test the balance ability and motor coordination of the mice. Results: With aging of the mice, the expression of ALKBH5 in the cerebellum increased gradually in an age-dependent manner. In the aged mice, but not middle-aged mice, the body weight, whole brain weight and cerebellum weight of ALKBH5-/- mice decreased by 15%, 10% and 21%, respectively (P<0.05). The expression of ALKBH5 in the Purkinje cells was much higher than that in other types of neural cells. Correspondingly, ALKBH5-deficiency caused 40% reduction in the number of Purkinje cells, as well as the length and density of neuronal dendrites in the aged mice (P<0.01). In addition, the time for the aged ALKBH5-/- mice to pass the balance beam was 70% longer than that of the wild type mice of the same age, with unstable gaits (P<0.01). Conclusions: Gene deficiency of RNA m6A demethylase ALKBH5 causes cerebellar atrophy, Purkinje neuron loss and damage in the aged mice. These changes eventually affect mice's motor coordination and balance ability. These results suggest that imbalanced RNA m6A methylation may lead to neurodegenerative lesions in the cerebellum of mice.

[Pay attention to the clinical application of radiofrequency ablation in the treatment of neuropathic pain].

Neuropathic pain is the pain triggered or caused by primary damage and dysfunction of the nervous system. Its pathogenesis is complex, involving changes in ion channel function, abnormal action potential generation and expansion, and central and peripheral sensitization. Therefore, it has always been the most intractable problem in clinical pain diagnosis and treatment, and there are many kinds of treatment methods. In addition to various oral drugs, nerve block, pulsed radiofrequency, radiofrequency ablation, central nerve electrical stimulation, peripheral nerve electrical stimulation, intra-thecal infusion system, craniotomy nerve decompression or carding, the dorsal root entry zone disfigurement, etc. various methods have mixed efficacy. So far, radiofrequency ablation of peripheral nerves is still the most simple and effective means for the treatment of neuropathic pain. In this paper, the definition, clinical manifestations, pathological mechanism and the treatment methods of radiofrequency ablation of neuropathic pain were expounded, in order to provide reference for related clinicians in radiofrequency ablation.

Clinical significance of extrathyroidal extension to major vessels in papillary thyroid carcinoma.

PURPOSE: Gross extrathyroidal extension (gETE) into major vessel is considered the most advanced stage of the locally advanced papillary thyroid cancer (PTC). Surgical intervention may not benefit some patients at this disease stage or even result in intraoperative death due to massive hemorrhage; however, it is still considered an effective strategy for most cases. The lack of description for this challenging invasion in PTC warrants detailed characterization of its pattern, risk factors, optimal surgical method, and prognostic value. METHODS: In total, 3127 patients diagnosed as having PTC were enrolled and categorized into two the following groups, namely the major vessel invasion (MVI) group (n = 30) and the control group (n = 3097). Data regarding clinicopathological and demographic characteristics, vascular invasion sites, postoperative complications, locoregional recurrence, distant metastasis, and surgical strategies were collected. Predictive disease-free survival (DFS) was also compared between the two groups. RESULTS: MVI was independently associated with invasion of the esophageal extension, age < 55 years, tumor size > 1 cm, lateral lymph node metastasis, and distant metastasis (P = 0.00; P = 0.01; 0.05; P = 0.00; P = 0.00, respectively). The difference in the predictive DFS between the two groups was significant (P = 0.00), and the difference remained significant even in patients with ETE when compared with patients without ETE (P = 0.00). Additionally, predictive DFS did not differ significantly between patients who received vessel repairment and those who received vessel resection (P = 0.28). CONCLUSIONS: This study first characterized the gross MVI pattern exhibited by PTC and the risk factors for MVI. Additionally, it demonstrated the DFS of patients with PTC. Extensive gross MVI significantly worsened the biological characteristics of PTC. Regardless of the high risk and difficulty of the operation, patients still benefited from the surgical intervention, and vessel repairment may be the optimal surgical strategy.

Prediction of endotracheal tube size in pediatric patients: Development and validation of machine learning models.

Objective: We aimed to construct and validate machine learning models for endotracheal tube (ETT) size prediction in pediatric patients. Methods: Data of 990 pediatric patients underwent endotracheal intubation were retrospectively collected between November 2019 and October 2021, and separated into cuffed and uncuffed endotracheal tube subgroups. Six machine learning algorithms, including support vector regression (SVR), logistic regression (LR), random forest (RF), gradient boosting tree (GBR), decision tree (DTR) and extreme gradient boosting tree (XGBR), were selected to construct and validate models using ten-fold cross validation in training set. The optimal models were selected, and the performance were compared with traditional predictive formulas and clinicians. Furthermore, additional data of 71 pediatric patients were collected to perform external validation. Results: The optimal 7 uncuffed and 5 cuffed variables were screened out by feature selecting. The RF models had the best performance with minimizing prediction error for both uncuffed ETT size (MAE = 0.275 mm and RMSE = 0.349 mm) and cuffed ETT size (MAE = 0.243 mm and RMSE = 0.310 mm). The RF models were also superior in predicting power than formulas in both uncuffed and cuffed ETT size prediction. In addition, the RF models performed slightly better than senior clinicians, while they significantly outperformed junior clinicians. Based on SVR models, we proposed 3 novel linear formulas for uncuffed and cuffed ETT size respectively. Conclusion: We have developed machine learning models with excellent performance in predicting optimal ETT size in both cuffed and uncuffed endotracheal intubation in pediatric patients, which provides powerful decision support for clinicians to select proper ETT size. Novel formulas proposed based on machine learning models also have relatively better predictive performance. These models and formulas can serve as important clinical references for clinicians, especially for performers with rare experience or in remote areas.

Lichen Sclerosus throughout Childhood and Adolescence: Not Only a Premenarchal Disease.

STUDY OBJECTIVE: To determine the frequency of persistence of vulvar lichen sclerosus (LS) through the pubertal transition and assess if the symptomatology and exam findings differ by menarchal status at onset of symptoms DESIGN: A retrospective cohort study SETTING: Academic tertiary care hospital PARTICIPANTS: Females aged 21 years or younger with a diagnosis of vulvar LS INTERVENTION: None MAIN OUTCOME MEASURES: Menarchal status at symptom onset, presenting symptoms, exam findings, persistence after menarche RESULTS AND CONCLUSIONS: Of the 196 patients who met criteria, 141 were premenarchal and 55 postmenarchal. Of these 55, 36 had postmenarchal symptom onset, and the others had premenarchal symptom onset or LS diagnosis. Over the data review period, 26 patients were followed through the pubertal transition, and 10 (38.5%) had continued symptoms of LS. The premenarchal group (n = 141) was significantly more likely than the symptom-onset postmenarchal group (n = 36) to present with vulvar itching (70.2% vs 52.8%; P = .048), vulvar bleeding (26.2% vs 5.6%; P = .008), and bowel symptoms (16.3% vs 0%; P = .009). The premenarchal group was significantly more likely on exam to have subepithelial hemorrhages (24.8% vs 5.6%; P = .01). The postmenarchal group had more clitoral adhesions (25.0% vs 4.3%; P < .0001) and loss of labia minora (47.2% vs 2.1%; P < .0001). Thirteen postmenarchal patients presented with dyspareunia. This study suggests that premenarchal LS can persist after menarche in about 40% of adolescents and can initially develop in postmenarchal adolescents. Initial symptoms and exam findings differ on the basis of menarchal status. Continued surveillance is recommended.

Use of Two Levonorgestrel Intrauterine Devices in a Patient with a Uterus Didelphys: A Case Report.

BACKGROUND: Intrauterine devices (IUDs) are contraindicated in patients with known uterine anomalies, eliminating an extremely effective contraceptive option. However, data regarding contraceptive desires in these patients are limited to a few case reports. CASE: A 20-year-old nulligravida with a uterus didelphys desired contraception after oral contraceptive pills and an etonogestrel implant failed. Despite extensive counseling, including Centers for Disease Control and Prevention guidelines regarding contraindications for IUD placement in the setting of a uterine anomaly, she desired to proceed with placement of 2 IUDs. Two 13.5-mg levonorgestrel IUDs were successfully placed into each uterine horn. SUMMARY AND CONCLUSION: In select patients with uterine anomalies, IUD placement can be a safe and effective option. This is especially important in adolescents who might be at increased risk for unintended pregnancy and poor obstetric outcomes.

Should we screen for Müllerian anomalies following diagnosis of a congenital renal anomaly?

INTRODUCTION: Despite the well-established embryological relationship in the development of renal and Müllerian structures, no clear guidelines exist regarding screening for Müllerian anomalies (MA) in the setting of a renal anomaly (RA). Delayed diagnosis of MA can have significant reproductive consequences. OBJECTIVE: To investigate the prevalence of coexisting MA in patients with congenital RA. STUDY DESIGN: This is a retrospective cohort study of females age 12-35 years with a diagnosis of RA, identified by diagnosis codes, who were followed for care between 2013 and 2020. Data were collected on demographics, medical history, clinical presentation, and imaging studies. Descriptive statistics were used to summarize the data. This study was IRB approved. RESULTS: A total of 465 patients were included in this study, of whom 326 patients (70.3%) had a pelvic evaluation during the study period. Of these 326 patients, 125 (38.3%) were found to have coexistent MA. About one-third of patients who underwent pelvic evaluation due to pain were found to have MA. For 69.6% (87/125) of patients with MA, the RA was diagnosed prior to the MA. The average age at time of RA diagnosis was 6.4 ± 8.8 years and the average age of MA diagnosis was 16.4 ± 6.9 years. Forty-eight (38.4%) patients had obstructive anomalies. Of the Müllerian obstructions, 93.8% were treated with urgent surgery and the remainder started on hormonal suppression. The prevalence of MA was dependent on the RA diagnosis (Figure). Of patients with a solitary kidney, 67.1% were diagnosed with MA. For other parenchymal RA, the prevalence of MA was 20-23%. In patients with solitary kidney, uterus didelphys was the most common MA (52.1%). Thirty percent of patients with a solitary kidney were diagnosed with an obstructive MA. CONCLUSIONS: In this study, 38% of patients with RA who underwent a pelvic evaluation were found to also have MA. Our study shows the strongest association between MA and solitary kidney, but also emphasizes a significant risk with other RA. Almost 40% of patients with diagnosed MA were found to have an obstruction that required urgent treatment. Delays in diagnosis and treatment of Müllerian obstructions can be detrimental for future reproductive health, due to risk of chronic pain, infertility, infection, and endometriosis. Given the high prevalence of MA in patients with RA, especially those with congenital solitary kidney, routine screening with pelvic ultrasound should be performed around the age of expected menarche.

Efficacy and safety of iodine-125 particle implantation for treatment of bone metastatic tumor pain: a retrospective analysis.

OBJECTIVE: Patients with advanced tumors often suffer from spinal metastatic tumor pain. The current drugs are less effective and have side effects. The objective was to explore the efficacy of iodine-125 particle implantation in the treatment of bone metastatic tumor pain. PATIENTS AND METHODS: In a retrospective study, a total of 27 patients with bone metastatic tumors who could not receive surgery or radiotherapy and chemotherapy were analyzed. All patients received conventional treatment, with the visual analog scale (VAS) of >3 points, and the daily onset pain of >3 times. All patients received CT-guided iodine-125 particle implantation to treat local painful lesions. VAS scores were recorded before treatment (T0) and 1 day (T1), 7 days (T2), 30 days (T3), 90 days (T4), and 180 days (T5) after treatment. Kaplan-Meier analytical method was used to calculate the local control rate (LCR) and survival rate (SR). RESULTS: All patients successfully completed the CT-guided iodine-125 particle implantation. There was no significant difference in VAS scores before and 1 day after surgery. However, compared with pre-operation, the VAS scores decreased at 7, 30, 90, and 180 days after surgery. The postoperative follow-up was 6-38 months, with a median of 16 months; the LCR at 1, 2, and 3 years after the follow-up were 87%, 51%, and 21%, respectively, and the SR was 84%, 43%, and 16%, respectively. Moreover, no serious adverse reactions were observed. CONCLUSIONS: Iodine-125 particle implantation was effective in the treatment of bone metastatic tumor pain without serious complications, and hence, can be used clinically.

Distal Vaginal Atresia with Spontaneous Perforation: A Case Report.

BACKGROUND: The definitive treatment of distal vaginal atresia is surgery, but menstrual suppression is often helpful for initial management. CASE: A 13-year-old presented with primary amenorrhea and progressive abdominal pain. She was diagnosed with distal vaginal atresia and started on hormonal suppression. She then re-presented with heavy vaginal bleeding, and follow-up imaging revealed that spontaneous perforation had occurred. There was now evidence of a tract leading from the obstructed vaginal bulge to the introitus. Vaginoplasty was complicated by the tortuosity of the tract. Under ultrasound guidance, a pull-through vaginoplasty was performed. SUMMARY AND CONCLUSION: Spontaneous perforation of an atretic vagina is rare, but in such cases, urgent vaginoplasty is indicated to prevent infection. Despite the presence of a spontaneous tract leading to the obstruction, vaginoplasty can be complex, and intraoperative ultrasound could be beneficial.

[Effects of N-trimethyl chitosan-recombinant tissue factor pathway inhibitor complex on avulsion flap with roll compaction in rat].

Objective: To investigate the effect of N-trimethyl chitosan-recombinant tissue factor pathway inhibitor (rTFPI) complex on avulsion flap with roll compaction in rat. Methods: The experimental methods were adopted. The N-trimethyl chitosan-rTFPI complex solution was prepared by ion cross-linking method. The morphology of the complex was observed by scanning electron microscope, and its diameter was measured. The encapsulation rate of rTFPI in the complex and drug loading rate of the complex was determined and calculated by enzyme-linked immunosorbent assay (ELISA) method (n=3). The concentration of rTFPI in the solution at 0, 10, 30, 45, 60, 90, 120, 240 minutes of storage was measured by ELISA method to observe the release of rTFPI, and its half-life was calculated (n=3). Twenty-four 6-week-old male Sprague-Dawley rats were divided into phosphate buffered saline (PBS) group, N-trimethyl chitosan alone group, rTFPI alone group, and N-trimethyl chitosan-rTFPI group according to the random number table, with 6 rats in each group. The avulsion flaps with roll compaction were prepared on the backs of rats with pedicles located on the line of the bilateral iliac spine and lifted from the surface of the muscle membrane. One injection of corresponding reagents was carried out immediately after in-situ suture and on post operation day (POD) 1, 2, and 3. General changes of the flap were observed on POD 1, 3, and 7. On POD 7, the survival area of the flap was measured and the survival rate of the flap was calculated; the flaps were divided into pedicle, proximal, middle, and distal segments, and the blood perfusion in the proximal, middle, and distal segment tissue of the flap was detected by the laser speckle blood flow imager; tissue samples in the middle of the flap were cut and stained with hematoxylin and eosin to observe the changes in tissue structure and the infiltration of inflammatory cells, and the numbers of embolized blood vessels and new blood vessels per 100 times visual field were counted. Data were statistically analyzed with one-way analysis of variance and least significant difference test. Results: The N-trimethyl chitosan-rTFPI complex had an irregular spherical structure with a diameter of 150-200 nm. The encapsulation rate of rTFPI in the complex and drug loading rate of the complex were (88.7±2.1)% and (2.83±0.09)%, respectively. The concentration of rTFPI in the solution of the N-trimethyl chitosan-rTFPI complex gradually increased with prolonged storage time, and the release was basically stable at 90 min, with half-life of (651±36) min. On POD 1, the distal parts of flaps of rats in N-trimethyl chitosan alone group darkened significantly. On POD 3, scabs and necrosis were relatively mild on the distal segment of the flaps of rats in rTFPI alone group and N-trimethyl chitosan-rTFPI group as compared with those of the other two groups. On POD 7, the necrosis boundaries of the flaps of rats in each group were clear. On POD 7, the flap survival rates of rats in rTFPI alone group and N-trimethyl chitosan-rTFPI group were (63±7)% and (73±5)%, respectively, which were significantly higher than (41±3)% in PBS group and (52±7)% in N-trimethyl chitosan alone group. Moreover, the flap survival rate of rats in N-trimethyl chitosan-rTFPI group was significantly higher than that in rTFPI alone group (P<0.05). On POD 7, the flaps of rats in each group had blood perfusion; the blood perfusion values in the proximal segment tissue of the rat flaps in N-trimethyl chitosan alone group and the blood perfusion values in the proximal, middle, and distal segment tissue of the rat flaps in rTFPI alone group and N-trimethyl chitosan-rTFPI group were significantly higher than those in PBS group (P<0.05 or P<0.01); the blood perfusion values in the distal segment tissue of the rat flaps in rTFPI alone group and the blood perfusion values in the middle and distal segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group were significantly higher than those in N-trimethyl chitosan alone group (P<0.05 or P<0.01); the blood perfusion value in the middle segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group was significantly higher than that in rTFPI alone group (P<0.01). On POD 7, inflammatory cells infiltrated more and cell edema was obvious in the middle segment tissue of the rat flaps in PBS group and N-trimethyl chitosan alone group. Compared with those of the previous two groups, the inflammation degrees in the middle segment tissue of the rat flaps in rTFPI alone group and N-trimethyl chitosan-rTFPI group were significantly milder, the number of embolized blood vessels was significantly decreased (P<0.05 or P<0.01), and the number of new blood vessels was significantly increased (P<0.05 or P<0.01). Compared with that of rTFPI alone group, the number of new blood vessels in the middle segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group increased significantly (P<0.05). Conclusions: The effect of sustained release of rTFPI can be achieved by loading rTFPI with N-trimethyl chitosan. Compared with rTFPI alone, the N-trimethyl chitosan-rTFPI complex can further improve the blood perfusion of the avulsion flaps with roll compaction in rat and improve the survival rate of the flap.

A Novel Technique for Securing a Bolster For Skin Grafting after Extensive Vulvar Resection.

Patients with stage III hidradenitis suppurativa of the vulva and adjacent areas, unresponsive to other therapies, may require extensive surgeries. These include excision of diseased areas on the buttocks, vulva, groins, and abdomen, followed by delayed skin grafting. Negative pressure wound therapy has been used over grafts, but it can be difficult to maintain a seal when extensive areas have been resected. We present a novel technique to bolster skin grafts for optimal success. A total vulvectomy and resection of the buttocks, groins, and abdomen are first performed for stage III HS, incorporating all diseased tissue. Negative pressure wound therapy is applied and changed on postoperative day 3-4. On postoperative day 7, split-thickness skin grafts are applied. The skin grafts are covered by Adaptic gauze (3M Company, Minn.), cotton, and a layer of Reston foam (3M Company, St. Paul, Minn.) which is cut to fit the size of the wound. Ostomy skin barriers (Hollister Incorporated, Libertyville, Ill.) are placed on the skin surrounding the excised areas. Pediatric Foley catheters are then placed through the ostomy skin barriers and tied together to prevent movement of the bolster. The use of ostomy skin barriers and pediatric Foley catheters to secure bolsters has not previously been described. We demonstrate a well-tolerated technique, using common surgical supplies, to provide consistent uniform pressure over the graft site. This technique also allows for easy bedside dressing change(s) when indicated.

[Analysis of correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis].

Objective: To examine the correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis. Methods: The clinical data of patients with unilateral papillary thyroid carcinoma who underwent total thyroidectomy and bilateral central lymph node dissection and ipsilateral cervical lymph node dissection from June 2016 to June 2018 at Department of Thyroid Surgery, West China Hospital, Sichuan University were analyzed retrospectively. A total of 317 patients, including 87 males and 230 females, aged (41.4±12.1) years (range: 16 to 75 years), were enrolled in this study. The risk factors of contralateral central lymph node metastasis were analyzed by χ2 test and Spearman correlation analysis. Results: There were 116, 69, 269, and 181 cases of pretracheal lymph node, prelaryngeal lymph node, ipsilateral central lymph node and contralateral central lymph node metastasis, respectively, and 16 cases of skipping metastasis. Univariate analysis showed that contralateral central lymph node metastasis was associated with gender, maximum tumor diameter, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, and ipsilateral central lymph node metastasis (all P<0.05). Spearman correlation analysis showed that male (rs=0.162, P=0.004), maximum tumor diameter>10 mm (rs=0.184, P=0.001), capsule invasion (rs=0.135, P=0.016), pretracheal lymph node metastasis (rs=0.394, P<0.01), prelaryngeal lymph node metastasis (rs=0.272, P<0.01) and ipsilateral central lymph node metastasis (rs=0.203, P<0.01) were independent correlation factors for contralateral central lymph node metastasis. Conclusion: For patients with unilateral papillary thyroid carcinoma with ipsilateral cervical lymph node metastasis, bilateral central lymph node dissection should be considered if male, tumor diameter>10 mm, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, or ipsilateral central lymph node metastasis.

Preparing for Puberty in Girls With Special Needs: A Cohort Study of Caregiver Concerns and Patient Outcomes.

STUDY OBJECTIVE: To characterize the patient population with cognitive or physical impairments that presents for anticipatory guidance of puberty, evaluate caregiver concerns with respect to puberty, and describe chosen management strategies and outcomes following menarche. DESIGN: Retrospective cohort study SETTING: Academic tertiary care women and children's hospital PARTICIPANTS: Eligible female patients with special needs up to age 26 years presenting for anticipatory guidance from 2009 to 2018 MAIN OUTCOME MEASURES: Primary outcomes included characterization of patients presenting for anticipatory guidance and their reasons for menstrual management. Secondary outcomes were satisfaction with menstrual management and bleeding patterns. RESULTS: A total of 61 patients presented for anticipatory guidance of puberty, on average 13.5 months prior to menarche. Compared to the overall adolescent population with special needs who presented for gynecologic care, patients who had autism spectrum disorder (ASD), were nonverbal, or had attention-deficit/hyperactivity disorder (ADD/ADHD) were more likely to present for a pre-menarchal visit to discuss anticipated pubertal development (P < .001, P = .009, and P = .04, respectively). More than half of families described potential behavioral changes as their main concern. The majority of post-menarchal patients (80%) desired hormonal management of menses, including 30% of patients who had placement of a levonorgestrel intrauterine device. In all, 96% of patients were satisfied with their final menstrual bleeding pattern; 50% achieved amenorrhea or light spotting. CONCLUSIONS: This study describes the important role of pre-menarchal reproductive counseling for girls with disabilities. Anticipation of puberty causes great anxiety in families and patients, especially those with ASD, ADD/ADHD, and non-verbal status. Providers should consider initiating these conversations early in pubertal development.

[Correlation analysis between serum ferritin level and liver damage in acute stage of dengue fever].

Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

[Preliminary practice of multidisciplinary cooperative vaccination management model for pediatric patients with hematological and oncological diseases].

Objective: To preliminarily establish the multidisciplinary cooperative vaccination management model for pediatric patients with hematological and oncological diseases, and to explore its feasibility. Methods: In this prospective study a total of 150 children with hematological and oncological diseases visited immunization clinic of Shanghai Children's Medical Center from March 2017 to August 2018 were enrolled in this study. After establishing the multidisciplinary team, designing vaccination plan, staff training, implementation and quality control, a multidisciplinary immunization clinic was set up and the vaccination plan were implemented. The implementation rate of vaccination immunization, the HBsAb level and serum hepatitis B surface antibody (HBsAb) level before and after treatment, the HBsAb level and serum immunoglobulin G antibody (IgG) levels of measles, mumps, rubella (MMR) before and 6 months after immunization, the vaccine-related adverse reactions were assessed prospectively. Chi-square test or Fisher exact test was used to compare the differences of antibody level. Results: A total of 124 cases had been vaccinated as planned, with a coverage rate of 82.7%. Among these cases, the difference of HBsAb positive rate before and after treatment was significant (62.9% (78/124) vs.13.7% (17/124), χ²= 63.489, P<0.01). In 64 cases that completed three doses of hepatitis B immunization, there was a significant difference in HBsAb positive rate before and 6 months after immunization (6.3% (4/64) vs. 98.4% (63/64), P<0.01). In 40 cases that completed MMR immunization, the IgG antibody positive rate for measles (22.5% (9/40) vs. 82.5% (33/40), χ²=31.746,P<0.01), mumps (22.5% (9/40) vs.82.5% (33/40), χ²=28.872,P<0.01), rubella (25.0% (10/40) vs.62.5% (25/40), χ²=11.429, P<0.01) before and 6 months after immunization were significantly different. Of the 421 doses of immunization, 25 (5.9%) doses reported controlled systemic or local adverse event. Conclusions: The immunization of pediatric patients with hematological and oncological diseases is of great importance. The newly-developed multidisciplinary cooperation immunization model for Chinese children with hematological and oncological diseases is feasible, and the immunization protocol is safe and has a certain effect.

Satisfaction With Hormonal Treatment for Menstrual Suppression in Adolescents and Young Women With Disabilities.

PURPOSE: To characterize the population of adolescents and young women with special needs presenting for gynecologic care, describe usage patterns of hormonal suppression methods, and evaluate outcomes of menstrual management. METHODS: This retrospective cohort study included females with special needs up to age 26 years presenting for menstrual management from 2009 to 2018. Demographic, social, and medical histories were collected to investigate effects on bleeding pattern and satisfaction with menstrual management. RESULTS: Of 262 patients who presented for menstrual complaints, final methods of treatment included combined hormonal contraceptives (30.9%), oral progestins (19.8%), depot medroxyprogesterone acetate (8.0%), etonogestrel implant (1.9%), and levonorgestrel intrauterine device (16.8%). Eighty-five percent of patients were satisfied with their final bleeding pattern. Patients with amenorrhea or light regular periods were more likely to be satisfied than patients with heavy or irregular bleeding (p < .001). Satisfied patients tried an average of 1.4 methods, compared to 1.8 methods tried by the unsatisfied group (p = .042). By the end of the study, 26.0% were amenorrheic and 12.8% had only light spotting. Satisfaction rates were similar with each method, including 88.4% with use of combined hormonal contraceptives, 82.5% with oral progestins, 93.3% with depot medroxyprogesterone acetate, 100% with etonogestrel implant, and 83.9% with levonorgestrel intrauterine device. CONCLUSIONS: Amenorrhea or light regular bleeding led to satisfaction in most patients. No hormonal method was superior. When counseling families and patients who present for menstrual suppression, emphasis should be placed on goals of treatment and expectations for outcomes, as light regular periods may be as acceptable as amenorrhea.
