A case of melanoma in situ of the central forehead repair by V-Y advancement flap and Burow graft.

Large defects on the face after Mohs surgery have posed significant reconstructive challenges. A 90-year-old man presented with melanoma in situ of the central forehead, which resulted in a 4.5cmx4.3cm defect after multiple stages of Mohs surgery. Although different approaches for forehead repair with nasal root involvement are possible, we demonstrate that the V-Y advancement flap and subsequent Burrow graft for nasal root repair represents a viable closure technique for large circular defects of the central forehead.

Perceptions and impact of patient reviews: a survey of academic dermatologists.

BACKGROUND: Patient reviews (PRs) have emerged as a method to assess patient experiences with healthcare in order to improve the quality of care. Both institutional and third-party organizations collect quantitative data and comments from these patient surveys, usually accessible to the public for review. Our study examined dermatologists' perceptions of PRs and assessed their impact on dermatologists. METHODS: A survey was sent to the Association of Professors of Dermatology listserv (response rate 30%). RESULTS: Most respondents disagreed with the statements that PRs are good for doctors (63%), good for patients (58%), helpful for doctors (58%), or that high PRs indicate being a good doctor (65%). The majority disagreed that PRs should be available publicly (60%). Respondents agreed that PRs contribute to depersonalization (60%), energy depletion or exhaustion (55%), added stress at work (70%), negativism/cynicism about work (60%), and diminished professional efficacy (29%). Self-identified female respondents were more likely to agree that PRs added stress to work compared to self-identified males (66% vs. 42%, P < 0.05). CONCLUSIONS: Overall, these findings suggest that PRs may negatively impact dermatologists' well-being and perceived stress levels.

The association between bronchopulmonary dysplasia grade and risks of adverse neurodevelopmental outcomes among preterm infants born at less than 30 weeks of gestation.

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a multifactorial disease with neurodevelopmental implications. This study aims to quantify the risks of adverse neurodevelopmental outcomes for each BPD grade among preterm infants born at less than 30 weeks' gestation. METHODS: We retrospectively studied infants who received care in our institution until at least 36 weeks postmenstrual age and had a formal neurodevelopmental assessment in our infant follow-up clinic using the Bayley Scales for Infant and Toddler Development (BSID). We assessed the association between BPD grade and adverse neurodevelopmental outcomes using descriptive statistics and regression models. RESULTS: Two hundred and fifty infants, including 89 (35.6%), 87 (34.8%), 65 (20.6%), and 9 (3.6%) with No BPD, Grade 1, Grade 2, and Grade 3 BPD, were included in the study. Small for gestational age, late pulmonary hypertension, dexamethasone administration, and adverse neurodevelopmental outcomes were more common as BPD grade increased. In a logistic regression analysis, Grades 2 and 3, but not Grade 1, BPD were associated with increased odds of a composite adverse neurodevelopmental outcome by 2.7 and 7.2 folds, respectively. A BSID domain-specific analysis showed that higher grades were associated with lower scores in the cognitive, gross motor, and fine motor domains. CONCLUSIONS: Grades 2 and 3 BPD, but not Grade 1, correlate with risks of adverse neurodevelopmental outcomes at a grade-dependent manner in our single-center cohort retrospective study. Further validation using a multi-center large cohort is warranted.

Oxygenation index in the first three weeks of life is a predictor of bronchopulmonary dysplasia grade in very preterm infants.

BACKGROUND: The new bronchopulmonary dysplasia (BPD) grading system was developed based on its correlation with long-term respiratory and neurodevelopmental outcomes and may provide better personalized prognostication. Identifying early-life predictors for accurate BPD grade prediction may allow interventions to be tailored to individual needs. This study aimed to assess whether oxygenation index (OI) dynamics in the first three weeks of life are a predictor of BPD grade. METHODS: A single-center retrospective study was performed. Generalized additive mixed modeling was used to model OI trajectories for each BPD grade subgroup. A multinomial regression model was then developed to quantify the association between OI dynamics and BPD grade. RESULTS: Two hundred fifty-four infants were identified for inclusion in the trajectory modeling. A total of 6,243 OI data points were available for modeling. OI trajectory estimates showed distinct patterns in the three groups, most prominent during the third week of life. The average daily OI change was -0.33 ± 0.52 (n = 85) in the No-BPD group, -0.04 ± 0.75 (n = 82) in the Low-Grade BPD group, and 0.22 ± 0.65 (n = 75) in the High-Grade BPD group (p < 0.001). A multinomial regression analysis showed the initial OI value and the average daily OI change both independently correlated with BPD grade outcomes after adjusting for birth gestation, birth weight z-score, sex, and the duration of invasive ventilation. CONCLUSION: Early-life OI dynamics may be a useful independent marker for BPD grade prediction. Prospective studies may be warranted to further validate the findings.

Machine learning for prediction of bronchopulmonary dysplasia-free survival among very preterm infants.

BACKGROUND: Bronchopulmonary dysplasia (BPD) is one of the most common and serious sequelae of prematurity. Prompt diagnosis using prediction tools is crucial for early intervention and prevention of further adverse effects. This study aims to develop a BPD-free survival prediction tool based on the concept of the developmental origin of BPD with machine learning. METHODS: Datasets comprising perinatal factors and early postnatal respiratory support were used for initial model development, followed by combining the two models into a final ensemble model using logistic regression. Simulation of clinical scenarios was performed. RESULTS: Data from 689 infants were included in the study. We randomly selected data from 80% of infants for model development and used the remaining 20% for validation. The performance of the final model was assessed by receiver operating characteristics which showed 0.921 (95% CI: 0.899-0.943) and 0.899 (95% CI: 0.848-0.949) for the training and the validation datasets, respectively. Simulation data suggests that extubating to CPAP is superior to NIPPV in BPD-free survival. Additionally, successful extubation may be defined as no reintubation for 9 days following initial extubation. CONCLUSIONS: Machine learning-based BPD prediction based on perinatal features and respiratory data may have clinical applicability to promote early targeted intervention in high-risk infants.

An Unusual Case of Primary Ileal Trichobezoar Causing Intussusception.

BACKGROUND Intussusception, which is the prolapse of one section of intestine into another, is a common cause of small-bowel obstruction in pediatric patients. Bezoars are concretions of ingested foreign material. Trichobezoars, which are bezoars made of hair, occur in the context of trichotillomania, the compulsive pulling of hair, and trichophagia, the eating of hair. If gastric trichobezoars grow to sufficient size, an intestinal extension can serve as a lead point for intussusception to occur. Rarely, hair passes completely through the stomach and forms a trichobezoar within the small bowel. This obstruction can also create lead points and cause intussusception. This is one of the few reported cases of intussusception due to a primary intestinal bezoar. CASE REPORT We present the case of an 8-year-old boy with an unknown history of trichophagia and a preliminary diagnosis of appendicitis. Upon imaging, a bowel obstruction related to a small-bowel intussusception was discovered to be the probable cause. A diagnostic laparoscopy revealed an ileo-ileal intussusception caused by an ileal bezoar. Conversion to exploratory laparotomy assisted in removing the causative bezoar. The patient recovered without postoperative complications. CONCLUSIONS We report a case of an isolated intestinal trichobezoar causing intussusception in a boy. While intussusception secondary to a trichobezoar most commonly occurs due to 'Rapunzel syndrome,' this case shows that it is possible for an intestinal trichobezoar to form without the presence of 'Rapunzel syndrome.' This unique cause of intussusception presented as a small-bowel obstruction, requiring evacuation of the bezoar.

Large mesenteric cyst mimicking an ovarian cyst in an 8-year-old: A case report.

INTRODUCTION AND IMPORTANCE: Pediatric mesenteric cysts, rare and usually benign intra-abdominal tumors, are a difficult preoperative diagnosis due to ambiguous clinical characteristics. The final diagnosis is typically established only during surgery or histological analysis. CASE PRESENTATION: An 8-year-old female presented with five days of worsening abdominal pain, associated with nausea, vomiting, and fever, as well as vague tenderness in the right quadrants on examination. Computed tomography imaging showed a 10.5 × 8.7 × 7 cm abdominal mass, most suspicious for a cystic mass of ovarian origin. Upon diagnostic laparoscopy, a mesenteric cyst extending to the root of the mesentery was visualized and entirely resected after conversion to an exploratory laparotomy. Histopathological examination of both the cystic fluid and specimen suggest a benign mesenteric cyst. CLINICAL DISCUSSION: Although mesenteric cysts are noticeably rare, it is important differential to consider in pediatric patients with non-specific symptoms like abdominal pain and distention, intestinal obstruction, or a palpable abdominal mass. Notably, these cysts can be managed successfully by complete surgical resection with an excellent outcome. CONCLUSION: This report recounts an interesting case of a large mesenteric cyst that mimicked an ovarian cyst in a pre-pubertal girl.
