RESUMEN

Background: Anorexia nervosa (AN) is a mental and behavioral health condition characterized by an intense fear of weight or fat gain, severe restriction of food intake resulting in low body weight, and distorted self-perception of body shape or weight. While substantial research has focused on general anxiety in AN, less is known about eating-related anxiety and its underlying neural mechanisms. Therefore, we sought to characterize 'anxiety to eat' in AN and examine the neurometabolic profile within the dorsal anterior cingulate cortex (dACC), a brain region putatively involved in magnifying the threat response. Methods: Women seeking inpatient treatment for AN and women of healthy weight without a lifetime history of an eating disorder (healthy controls; HC) completed a computer-based behavioral task assessing 'anxiety to eat' in response to images of higher (HED) and lower (LED) energy density foods. Participants also underwent magnetic resonance spectroscopy of the dACC in a 3T scanner. Results: The AN group reported greater anxiety to eat both HED and LED foods relative to the HC group. Both groups reported greater anxiety to eat HED foods relative to LED foods. The neurometabolite myo-inositol (mI) was lower in the dACC in AN relative to HC, and mI levels negatively predicted anxiety to eat HED but not LED foods in the AN group only. mI levels in the dACC were independent of body weight, body mass, and general anxiety. Conclusions: These findings provide critical new insight into the clinically challenging feature and underlying neural mechanisms of eating-related anxiety, and indicate mI levels in the dACC could serve as a novel biomarker of illness severity that is independent of body weight to identify individuals vulnerable to disordered eating or eating pathology as well as a potential therapeutic target.

RESUMEN

PURPOSE: Severe postoperative edema after eyelid surgery can have negative clinical and psychological effects. In this study, we investigated whether surgical factors, including surgical techniques and suture type, were associated with clinically significant eyelid edema (CSEE). METHODS: A chart review was performed on 269 patients who underwent upper eyelid blepharoplasty with or without external levator advancement by 2 surgeons at a single institution between January 2021 and December 2022. Postoperative photos were graded by 2 physicians for eyelid edema using a standardized grading scale ranging from 0 (no edema) to 3 (severe edema). CSEE was defined either as having a grade of 3 at any point postoperatively or any grade that was 1 or greater after 90 days postoperatively. Logistic regression controlling for race was used for analysis; the statistical significance level was defined as p < 0.05. RESULTS: Of 269 patients, 56 developed CSEE. Of those who underwent blepharoplasty with mini crease enhancement (closure with every other bite incorporating levator aponeurosis), 40.5% developed CSEE versus 12.5% of those without (p < 0.001). Patients with lid crease formation using buried interrupted sutures had greater CSEE than those with externalized interrupted sutures removed at 1 week (43.8% versus 11.5%, p < 0.01). There was no increased risk of CSEE with additional procedures performed versus blepharoplasty alone. CONCLUSIONS: Patients who underwent blepharoplasty with mini crease enhancement, where more than 4 sutures are placed from skin to levator, and/or had buried suture lid crease formation had greater rates of CSEE.

RESUMEN

BACKGROUND: Free tissue transfer is a mainstay treatment for lower extremity soft tissue injuries. When the traditional cross-leg flap cannot provide enough coverage, a cross-leg free flap (CLFF) is a limb-saving alternative. The aim of this study is to conduct a systematic review of the literature published on the CLFF. METHODS: We conducted a systematic review of articles describing the CLFF, according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Inclusion criteria included articles with primary data on the CLFF. Exclusion criteria included those describing pedicled cross-leg flaps or lacking complete data. Data analysis was performed using SPSS 29.0. RESULTS: Our review included 28 articles encompassing 130 patients who underwent free tissue transfer. Most were male (63.8%) with a mean age of 32.4 years. Latissimus dorsi was the most common flap type (30.0%), followed by vertical rectus myocutaneous (20.0%). Average flap size was 301.8 cm2 , with trauma in the lower third of the leg being the most common indication (73.1%). The contralateral posterior tibialis was the most common recipient artery (84.1%) followed by the anterior tibialis (9.5%). Complications included amputation (1.4%), partial graft loss, thrombosis, hematoma, prolonged pain, nonunion, and seroma; a forest plot was used to illustrate the low overall adverse events rate. Although bivariate analysis identified age, flap size, type, location, and donor site as variables significantly impacting the incidence of complications (p < .05), this was not sustained in a multivariate logistic regression model. CONCLUSION: The CLFF remains an excellent option for limb salvage when a suitable recipient vessel is unavailable. Our review demonstrates 1.4% flap failure and an acceptable complication rate. While most cases in our review describe muscle flaps, we report a complex case of limb salvage using an unusually large anterolateral thigh flap.

RESUMEN

Follicular lymphoma (FL) develops through a stepwise acquisition of cooperative genetic changes with t(14;18)(q32;q21)/IGH::BCL2 occurring early at the pre-B stage of B-cell development. Patients with FL typically show an indolent clinical course, remitting and relapsing with the eventual development of resistance to treatments. Interestingly, the majority of transformed FL do not progress directly from FL but originate from their clonally related lymphoma precursor (CLP) cells. To examine whether such divergent tumour evolution also underpins the relapses in patients with early-stage FL, we investigated by targeted next-generation sequencing 13 cases (stage I = 9, stage II = 4), who showed complete remission (mean: 5 years; range: 1-11.5 years) following local radiotherapy but subsequently relapsed (≥2 in 5). A clonal relationship between the diagnostic FL and relapses was confirmed in 11 cases. In six cases, common and distinct variants were seen between the paired diagnostic and relapsed lymphomas, indicating their divergent evolution from a CLP. In two cases, different B-cell clones were involved in the diagnostic and relapsed lymphomas, including one case involving two different BCL2 translocations. In the remaining five cases, the relapsed lymphoma developed via a linear progression (n = 4) or a mixed evolutionary path (n = 1). These findings may bear important implications in the routine diagnosis and management of relapsed FL. © 2023 The Authors.

RESUMEN

Purpose: To evaluate the effectiveness, tolerability, and safety of the Nictavi Tarsus Patch™ (NTP) in inducing temporary eyelid closure for the management of lagophthalmos in the pediatric and young adult population. Methods: We prospectively enrolled 20 patients <21 years of age who had previously been managed for lagophthalmos to trial the NTP in clinic. Inter-palpebral fissure distance (IPFD) was compared before and after the placement of the NTP in the eyes-closed position using paired t-tests. Subjects then underwent a 3-night home trial with the NTP, and parent and subject perceptions of effectiveness, comfort, and complications with the patch were analyzed using Likert scale survey questions. Results: Twenty subjects ages 2-20 years with paralytic (65%) and non-paralytic (35%) lagophthalmos were enrolled. The NTP improved lagophthalmos from a mean pre-placement IPFD of 3.3 mm to post-placement IPFD of 0.4 mm (p < 0.01). Overall, 80% of subjects achieved successful eyelid closure defined as ≤1 mm of post-placement IPFD. When stratified by subtype, 100% of subjects with paralytic lagophthalmos achieved successful eyelid closure compared to 71% of subjects with non-paralytic lagophthalmos. On a scale of 1 (worst) to 5 (best), parents rated the NTP at 4.3±0.7 for comfort while wearing, 4.3±1.0 for comfort in removing, 4.6±0.7 for ease of use, and 4.3±0.9 for effectiveness. Ninety-three percent of parents reported preferring NTP to other eyelid closure methods previously tried and indicated that they would use it again. Conclusion: The NTP is an effective, tolerable, and safe method of eyelid closure for children and young adults.

RESUMEN

PURPOSE: To investigate demographic and physiological variables associated with clinically significant edema after upper eyelid surgery. METHODS: A retrospective chart review was performed on patients who underwent blepharoplasty or external levator advancement with or without lid crease formation between January 2018 and January 2021 at the University of Southern California. Age, sex, pertinent medical history (medications causing edema and comorbidities), and pertinent surgical procedures were all collected. Postoperative photos were graded by two independent physician graders on a newly developed photographic scale ranging from 0 (no edema) to 3 (severe edema). Clinically significant edema of the eyelids was defined as Grade 3 edema at any postoperative point or ≥ Grade 1 edema after 90 days post operation. Patients without postoperative photos were excluded. Mann-Whitney U test, Fisher's exact test, and χ2 test were used to compare groups with and without significant edema. All analyses were conducted using SAS version 9.4 (SAS Institute Inc.) with α=0.05. RESULTS: Out of 217 patients, East Asian participants had higher odds of developing edema than White participants (odds ratio, 7.92; CI, 3.15-19.93, p < 0.0001) and Hispanic participants (odds ratio, 3.47; CI, 1.51-7.97, p = 0.003). Southeast Asian participants also had higher odds of developing CSEE than White participants (odds ratio, 6.19; CI, 1.71-22.43, p = 0.006). Fifty-four (24.9%) patients had clinically significant edema. Although BMI, medical comorbidities, medication use, and age did not affect edema, there was a statistically significant relationship between race and incidence of edema (p = 0.0001). Those in the CSEE group were also more likely to require reoperation (p = 0.0143). CONCLUSIONS: There is a statistically significant relationship between Asian race and the incidence of clinically significant eyelid edema. CSEE is associated with a higher incidence of reoperation.

RESUMEN

BACKGROUND: Sight-threatening complications from retained orbital and intraocular foreign bodies are frequently reported in literature. Delays in diagnosis can result in severe complications, including choroidal neovascularization, infection, and irreversible vision loss. Therefore, it is imperative that emergency physicians consider the possibility of orbital and intraocular foreign bodies when evaluating patients with acute facial trauma. CASE REPORT: A 91-year-old woman with a history of laser-treated glaucoma and cataracts presented to an outside emergency department after a ground-level fall. A maxillofacial noncontrast computed tomography scan showed no facial fractures or hemorrhage, but a 41 mm × 4 mm foreign body within the intraconal compartment of the right orbit was identified. The object was presumed to be an implanted glaucoma drainage device, and the patient was discharged without antibiotics. One day after discharge, the patient developed right periorbital swelling and erythema with increasing purulent discharge and skin thickening, ultimately requiring transfer to our facility for management of complex right orbital cellulitis, orbital compartment syndrome, and surgical foreign body removal. Despite globe exploration and surgical intervention, the patient developed a frozen globe with no light perception in the right eye. Why Should an Emergency Physician Be Aware of This? Subtle ophthalmologic emergencies such as sight-threatening foreign bodies can be challenging to diagnose on imaging, particularly with the advent of implantable ocular technology. When an orbital foreign body is discovered in the context of facial trauma, early ophthalmology consultation should be considered.

RESUMEN

ABSTRACT: Consort allergic contact dermatitis (CACD) develops following exposure to an allergen originating from another individual. The diagnosis is often not straightforward. We conducted a systematic review to characterize patient demographics, clinical features, consort types, responsible products, and associated allergens in CACD. A literature search was conducted in PubMed, EMBASE, Web of Science, and CINAHL Complete from inception to July 2020. In total, 183 articles describing 261 patients with CACD were included. Mean age was 40.9 years with female predominance (62.8%). The most common body sites involved were the face (48.6%), hand (30.4%), arm (20.9%), neck (17.8%), and genitals (11.5%). The most common consorts were partners/spouses (50.0%, of which 29.9% were related to sexual activity), children (19.4%), and healthcare providers (7.8%). Allergens were mainly encountered via direct contact with consorts (80.5% of cases). A caregiver relationship was involved in 27.6% of cases, and the consort's occupation in 14.6%. The most frequently implicated products were medications (35.6%), plants/botanicals (11.7%), and fragrances (8.7%). Patch testing identified 125 unique allergens in CACD. CACD can occur in relation to many individuals encountered throughout life. Caregivers may represent a high-risk group for developing CACD. Obtaining a holistic history encompassing social, sexual, and occupational factors can aid in the diagnosis.

RESUMEN

Objective: We evaluated the safety and efficacy of an augmented BroadBand Light (BBL™) protocol on the upper and lower eyelids in improving meibomian gland dysfunction (MGD) and/or dry eye disease (DED). Background: DED, often associated with MGD, can cause significant morbidity and accounts for 3.54 billion U.S. dollars of health care spending yearly. Intense pulsed light (IPL) has been used to treat MGD DED with some success. BBL therapy, a high-quality IPL machine, shows much promise for decreasing inflammation and redness in rosacea, as well as hyperpigmentation from sun damage. Methods: A retrospective medical chart review was performed for MGD DED and/or hyperpigmentation patients who received BBL therapy between January 1, 2015, and February 28, 2020. Inclusion criteria included patients who underwent at least one BBL treatment. Each treatment involved the upper and lower eyelids, as well as cheeks, nose, and face. Each MGD DED subject completed the Ocular Surface Disease Index (OSDI) and underwent pre- and post-treatment standard clinical examinations. Results: Forty-seven patients had treatment without significant adverse effects; all patients with MGD DED reported improvement in their dry eye or blepharitis. BBL was determined to be a safe and effective treatment. There were no changes in visual acuity (p = 0.555) and OSDI scores were improved (p = 0.016). There was one case each of mild corneal/conjunctival abrasion, temporary hyperpigmentation, and two of temporary eyelash thinning. Patients with MGD also showed significant improvement in blepharitis and reduced hordeolum frequency after BBL treatment. Conclusions: This novel IPL/BBL protocol appears safe and effective for treating dry eye and blepharitis.
