ABSTRACT
PURPOSE: Bariatric surgery is considered the main treatment option for patients with severe obesity. The objective of our study is to compare intra- and postoperative outcomes between the robotic and laparoscopic approaches within the sleeve gastrectomy (SG), duodenal switch (DS), and Roux-en-Y gastric bypass (RYGB). MATERIALS AND METHODS: The data from the MBSAQIP were collected for patients who underwent SG, DS, and RYGB between 2015 and 2021. The postoperative and procedural outcomes including 30-day morbidity and mortality as well as operation length were analyzed using regression models. RESULTS: Our analysis included 1,178,886 surgeries with SG comprising the majority (70%) followed by RYGB (28%) and DS (1%). Other than a higher adjusted risk of unplanned reoperation for robotic RYGB (relative risk (RR) 1.07) and a statistically significant higher rate of postoperative wound disruption in robotic SG for robotic surgery (RR 1.56), there were no statistically significant between-approach differences including infection, wound disruption, death, or reoperation for DS, RYGB, or SG. Our data showed no significant difference in anastomotic leak rate between laparoscopic and robotic approaches in either the DS (p = 0.521) or RYGB (p = 0.800) procedures. Across our study period, the median operation lengths decreased significantly per year for both the robotic SG and DS. CONCLUSIONS: Robotic and laparoscopic bariatric surgical procedures have statistically similar 30-day patient outcomes. Robotic bariatric procedures do have significantly longer median operative times than laparoscopic procedures. The decision to use a robotic approach or laparoscopic approach should be made based upon surgeon experience and possibly cost.

Laryngeal atresia is a rare congenital condition that presents with hypoxia and failed intubation attempts at birth. When diagnosed prenatally, options exist to obtain airway access during delivery. However, postnatal diagnosis requires a high degree of clinical suspicion and the prompt initiation of surgical airway management in order to avoid morbidity and mortality.
ABSTRACT
BACKGROUND: The existing data on the link between body mass index (BMI), operative characteristics, and surgical outcomes across orthognathic surgery are limited. PURPOSE: The purpose was to measure the association between BMI and early postoperative outcomes in orthognathic surgery. STUDY DESIGN, SETTING, AND SAMPLE: This is a retrospective cohort study of patients (n = 118) aged > 14 years undergoing bimaxillary orthognathic surgery between 2015 and 2018 by a single surgeon within the Kaiser Permanente Northern California-integrated healthcare system. Patients undergoing unilateral or additional procedures, history of prior orthognathic surgery, or pre-existing pain conditions were excluded. PREDICTOR VARIABLE: The predictor variable was BMI measured as a continuous (kg/m2) and categorical variable (underweight/normal, overweight, obese). MAIN OUTCOME VARIABLE(S): The primary outcome variables were additional postoperative antibiotics, increased postoperative visits, wound dehiscence, and wound infection. The secondary outcome variables were total operative and anesthesia time. COVARIATES: The demographic covariates included age, sex, and race/ethnicity. The clinical covariates included history of obstructive sleep apnea, Mallampati score, tobacco use, American Society of Anesthesia classification, thyromental distance, history of difficult intubation, and Angle's classification. ANALYSES: Bivariate and multivariate analyses were performed to measure the associations between BMI and the primary and secondary outcomes. Multivariable logistic regression analyses were used to measure associations between BMI and the postoperative outcomes. Statistical significance was defined as P < .05. RESULTS: The study sample was composed of 118 subjects with a mean age of 26.91 years (standard deviation 9.43). Forty-seven percent (n = 55) were male, and the mean BMI was 25.13 (standard deviation 5.19). BMI category was significantly associated with age, with increasing age associated with higher BMI category (P = .02). According to the bivariate and multivariable logistic regression analyses, controlling for age, race/ethnicity, BMI, and total operative time, increased total operative time was associated with additional postoperative antibiotics (odds ratio = 1.03, 95% confidence interval: 1.01, 1.05), and increased postoperative appointments (odds ratio = 1.02, 95% confidence interval: 1.01, 1.04). No significant association between BMI and other clinical or operative characteristics was seen aside from American Society of Anesthesia classification. CONCLUSION AND RELEVANCE: Elevated BMI was not associated with worsened operative characteristics or postoperative outcomes. This supports the suitability of orthognathic surgery in a BMI-diverse population.

Importance: Despite interest in therapy de-escalation for survivors of human papillomavirus-mediated oropharyngeal squamous cell carcinoma (HPV-positive OPSCC), the association of de-escalated therapy with patient-reported quality of life (QoL) outcomes and burden of depressive symptoms remains unclear. Objective: To identify associations between clinicopathologic and therapeutic variables with patient-reported QoL outcomes and depression symptom burden in patients with HPV-positive OPSCC, who were enrolled in a therapy de-escalation trial. Design, Setting, and Participants: In this nonrandomized controlled, open-label, curative-intent therapy de-escalation clinical trial in adults with stage I, II, and III HPV-positive OPSCC, patients were recruited from a high-volume head and neck oncology practice. Main Outcomes and Measures: The main outcomes of this study included quantitative, patient-reported QoL and depression symptoms per well-validated inventories. Patient-reported QoL was based on Functional Assessment of Cancer Therapy-Head & Neck (FACT-HN) scores (range, 0-148; lower score indicates inferior QoL). Patient-reported depression-related symptom burden was based on Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR) scores (range, 0-27; a higher score indicates a higher burden of depression symptoms). Baseline clinicopathologic and treatment variables were paired with FACT-HN and QIDS-SR scores at baseline, 3, 6, 12, 24, and 36 months. Linear mixed-effect models with a random intercept were used for each participant and fixed effects for other measures. Regression coefficients are reported with 95% CIs. Results: A total of 95 patients were followed up for a median (IQR) of 2.2 (1.6-3.2) years. Of these, 93 patients (98%) were male with a mean (SD) age of 60.5 (8.2) years. Overall, 54 participants (57%) had a history of current or former smoking, 47 (50%) underwent curative-intent surgery (with or without adjuvant therapy), and 48 (50%) underwent primary radiotherapy (with or without chemotherapy). The median (IQR) radiotherapy dose was 60 (60-70) Gy. Five deaths and 2 recurrence events were observed (mean [SD] recurrence interval, 1.4 [1.5] years). A higher radiotherapy dose was the only modifiable factor associated with inferior patient-reported QoL (lower FACT-HN) (coefficient, -0.66 [95% CI, -1.09 to -0.23]) and greater burden of depression-related symptoms (higher QIDS-SR) (coefficient, 0.11 [95% CI, 0.04-0.19]). With the 70-Gy dose as reference, improvements in FACT-HN and QIDS-SR scores were identified when patients received 51 to 60 Gy (coefficient, 12.75 [95% CI, 4.58-20.92] and -2.17 [-3.49 to -0.85], respectively) and 50 Gy or lower (coefficient, 15.03 [4.36-25.69] and -2.80 [-4.55 to -1.04]). Conclusions and Relevance: In this nonrandomized controlled, open-label, curative-intent therapy de-escalation trial, a higher radiotherapy dose was associated with inferior patient-reported QoL and a greater burden of depression-related symptoms. This suggests opportunities for improved QoL outcomes and reduced depression symptom burden with a reduction in radiotherapy dose. Trial Registration: ClinicalTrials.gov Identifier: NCT04638465.

BACKGROUND: Variation in practice exists for temperature probe positioning during stabilization of very preterm infants (<32 weeks gestation). We explored the influence of temperature probe sites on thermoregulation. METHODS: An open-label, stratified, balanced, parallel, randomized trial was conducted. Inborn infants were randomly assigned temperature probe to the axilla or to the upper back. The primary outcome was normothermia (local range: 36.8-37.3 °C and World Health Organization (WHO) range: 36.5-37.5 °C) at admission to the neonatal intensive care unit. RESULTS: Between 1 November 2018 and 4 July 2022, 178 infants were randomly assigned to one of the two sites (n = 89 each), 175 included in the final analysis. Normothermia (local range) was achieved for 39/87 infants (44.8%) assigned to the upper back compared to 28/88 infants (31.8%) assigned to the axilla [risk difference:13%; 95% CI -1.3-27.3]. Normothermia (WHO range) was achieved for 78/87 infants (89.7%) assigned to the upper back compared to 70/88 infants (79.6%) assigned to the axilla [risk difference:10.1%; 95% CI -0.5-20.7]. No infant recorded temperatures >38 °C or developed skin injury. CONCLUSIONS: In very preterm infants, upper back site was equally effective as the axilla in maintaining normothermia, with no increase in adverse events. CLINICAL TRIAL REGISTRATION: The study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000293965). IMPACT: Substantial variation in practice exists for the site of securing a temperature probe during delivery room stabilization of very preterm infants and the influence of temperature probe site on thermoregulation remains unknown. In this study, upper back site was equally effective as the axilla in maintaining normothermia, with no increase in adverse events. Clinicians could adopt upper back site for maintaining normothermia. This study may contribute data to future international participant data prospective meta analysis of randomized controlled trials worldwide on temperature probe positioning in very preterm infants, increasing translation of research findings to optimize thermoregulation and clinical outcomes.

Introduction: The most prevalent endocrine cancer in the world is thyroid cancer, and its incidence is on the rise. The distinction between benign and malignant thyroid nodules must be made, which is why fine needle aspiration cytology of thyroid lesion is necessary and required. This study aimed to find out the prevalence of thyroid malignancy among fine needle aspiration cytology of thyroid lesions in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among fine needle aspiration cytology of thyroid lesions in a tertiary care centre after obtaining ethical approval from the Institutional Review Committee. Data from 13 April 2020 to 13 April 2023 was collected between 19 May 2023 to 19 June 2023. All the patients with complete hospital record data were included in this study. However, repetitive fine needle aspiration cytology of thyroid lesion were excluded from the study. Fine needle aspiration cytology diagnoses were categorized in this study as per the Bethesda system for reporting thyroid cytopathology. The point estimate was calculated at a 95% Confidence Interval. Results: Among 398 fine needle aspiration cytology of thyroid lesions, thyroid malignancy was seen in 12 (3.02%) (1.34-4.70, 95% Confidence Interval) patients. Conclusions: The prevalence of thyroid malignancy was found to be lower than other studies done in similar settings. Keywords: cytology; malignancy; prevalence; thyroid.

OBJECTIVE: Our aim was to determine the need for otolaryngology care within the homeless population, identify barriers to access that the homeless population may face, and develop a model system which would address these needs with respect to the barriers. METHODS: A retrospective chart review of 812 patients seen between 1/25/16-3/21/2020 was performed. Charts were obtained from homeless patients seen at free general clinics held shelters in Chicago, IL (781 charts) and in Champaign, IL (31 charts). Records reporting at least one otolaryngology disease in a patient experiencing homelessness were included in this study. Patients were considered homeless if they resided at the shelter at the time of their appointment. To determine common barriers to care, a simple yes/no questionnaire was administered to residents at west-side Chicago homeless shelters. Questions addressed barriers to health care access that had been mentioned by patients seen at free clinics. RESULTS: Chart review findings demonstrated that 14.3% (n = 142) of all homeless patients seen at free in-shelter clinics were seen for ENT-related disorders. Survey results revealed that 76.3% (n = 71) of respondents believed that telemedicine services would be useful in shelters. 74.2% (n = 69) stated they were unable to afford prescribed medications. 93.5% (n = 87) stated that better access to transportation would increase their likelihood of seeking care. CONCLUSIONS: In our attempt to bridge this inequity, we have launched a hybrid in-person/virtual care program to improve access to otolaryngology care for the homeless community. LEVEL OF EVIDENCE: N/A Laryngoscope, 134:2705-2709, 2024.

Introduction: Griscelli syndrome (GS) is a very rare autosomal recessive disorder, belongs to group of "silvery hair syndromes" which includes Chediak-Higashi syndrome (CHS) and Elejalde syndrome. Hair light microscopy helps in the differentiation of GS and CHS, as both manifest with clinical features. Trichoscopy is useful in the diagnosis of many hair shaft disorders. Here, authors describe the trichoscopic features of GS in skin of color. Materials and Methods: This was an observational study conducted in a private dermatology clinic and in a tertiary care hospital. A total of 5 cases of suspected GS were referred by pediatrician. Consent was obtained. The demographic data in terms of age, gender, consanguinity, and clinical history was documented. Trichoscopic examination was performed with FotoFinder videodermoscope with 20× magnification, the clinical images were captured with Medicam 1000. Trichoscopy showed large and irregular pigment clumps in 4 cases. One case demonstrated hypopigmentation of hair without pigment clumps [Figure 3a]. Results: Trichoscopy showed large and irregular pigment clumps in 4 cases. One case demonstrated hypopigmentation of hair without pigment clumps. Conclusion: Trichoscopy shows characteristic features GS. It is a useful method when facility for light or polarized microscope is unavailable.
ABSTRACT
Melasma, a chronic pigmentary skin condition mainly affecting the face, remains a challenge despite the availability of several options for treatment. Many melasma patients are not satisfied with treatment outcomes. Tranexamic acid (TXA), an anti-fibrinolytic drug has shown promising results in patients with melasma. Evidence from several clinical studies has surfaced on efficacy and tolerability of TXA in these patients. It can be used as monotherapy or adjuvant with other therapies. Currently, there is no published consensus or guideline document for its use in the treatment of melasma. TXA is available for oral use, topical use as well as an injection. In this article, a consensus of Indian experts is prepared based on the available literature and experience with use of oral TXA in melasma. This review article might help clinicians for use of oral TXA appropriately while treating melasma.
ABSTRACT
Purpose: The primary objective of the study was to understand the therapeutic inertia in treatment and management of plaque psoriasis among dermatologists, along with determining the preferred treatment choices for management of plaque psoriasis; it also included the resulting treatment satisfaction among patients. The secondary objective was to identify the gaps in terms of knowledge and attitude among dermatologists and the expectations of patients. Patients and Methods: A multicentre, cross-sectional quantitative survey was conducted among dermatologists and patients with moderate to severe plaque psoriasis across India. The interviews were conducted either face to face or via telephone between September and November 2020, using structured and validated questionnaires based on specific themes. The data obtained were statistically analysed, wherever applicable. Results: Overall, 207 adult patients with moderate-to-severe plaque psoriasis and 303 dermatologists were interviewed. Post experiencing symptoms, 44% of the patients visited general physicians for treatment and there was an average 7.8-month delay by the patients to consult a dermatologist. Approximately one-fourth of patients used home remedies before seeking medical help. One-third of dermatologists used the Psoriasis Area and Severity Index (PASI) for assessing the disease severity. Majority of dermatologists preferred combination therapy for their patients. The lack of quick resolution and side effects were the major reasons for changing the treatment. Overall, only 35% of the patients complied to current treatment. Satisfaction with existing forms of therapies was highest for mild plaque psoriasis (62%) as confirmed by dermatologists, while 52% of the overall patients were satisfied with their therapy. Majority of the patients (64%) affirmed living with plaque psoriasis impacted their lives. Conclusion: This first-of-its-kind survey in India highlighted the gaps in terms of the disease journey between dermatologists and patients. The survey emphasises the need for shared decision-making and may benefit dermatologists in suggestive modifications of the treatment algorithm and disease management in clinical settings.
ABSTRACT
BACKGROUND: Literature on the dermoscopic patterns of basal cell carcinoma (BCC) in India is limited. AIM: To describe the dermoscopic pattern and dermoscopic-histopathological correlation in a large cohort of patients with BCC from India, with a particular focus on skin of colour (SOC). METHODS: This retrospective study was conducted under the aegis of the Dermatoscopy Society of India. Clinical details were collected, and two lead authors independently analysed dermoscopic images of BCC for a predefined set of characteristics. Histopathological slides/blocks were reviewed, and dermoscopic-histological correlation attempted. RESULTS: In total, 143 patients with BCC and skin phototypes IV-VI were included. The mean largest BCC diameter was 3.10 ± 3.68 cm and there was a significant but weak association between duration and largest dimension of the lesion (Spearman ρ = 0.33, P < 0.01). Nearly half of the cases were diagnosed with pigmented BCC and the most common histological subtype was nodular BCC (37.9%). Dermoscopically, blue-grey dots and arborizing vessels were the most common features (60.0%). Pigmentary changes were found in the majority of cases, and included blue-white veil, blue-grey ovoid nests and maple leaf-like areas. A third of our patients had short linear telangiectasia, polymorphic vessels and regular dotted vessels, and another third exhibited a dermoscopic rainbow effect. Arborizing vessels were significantly more common with micronodular (78.9%) and nodular variants (74.1%, P = 0.05), whereas regular dotted vessels (68.4%, P = 0.04), blue-white veil (84.2%, P = 0.02) were significantly associated with micronodular variant. CONCLUSION: The dermoscopic patterns of blue-white veil and regular dotted vessels are indicators towards micronodular BCC in SOC and can help in prioritizing treatment.

OBJECTIVE: To broadly synthesize the literature regarding rural health disparities in otolaryngology, categorize findings, and identify research gaps to stimulate future work. STUDY DESIGN: Scoping review. DATA SOURCES: A comprehensive literature search was performed in the following databases: PubMed/MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Google Scholar, and CINAHL. REVIEW METHODS: The methods were developed in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Peer-reviewed, English-language, US-based studies examining a rural disparity in otolaryngology-related disease incidence, prevalence, diagnosis, treatment, or outcome were included. Descriptive studies, commentaries, reviews, and letters to the editor were excluded. Studies published prior to 1980 were excluded. RESULTS: The literature search resulted in 1536 unique abstracts and yielded 79 studies that met final criteria for inclusion. Seventy-five percent were published after 2010. The distribution of literature was as follows: otology (34.2%), head and neck cancer (20.3%), endocrine surgery (13.9%), rhinology and allergy (8.9%), trauma (5.1%), laryngology (3.8%), other pediatrics (2.5%), and adult sleep (1.3%). Studies on otolaryngology health care systems also accounted for 10.1%. The most common topics studied were practice patterns (41%) and epidemiology (27%), while the Southeast (47%) was the most common US region represented, and database study (42%) was the most common study design. CONCLUSION: Overall, there was low-quality evidence with large gaps in the literature in all subspecialties, most notably facial plastic surgery, laryngology, adult sleep, and pediatrics. Importantly, there were few studies on intervention and zero studies on resident exposure to rural populations, which will be critical to making rural otolaryngology care more equitable in the future.

Anthracycline chemotherapeutics are highly effective, but their clinical usefulness is hampered by adverse side effects such as cardiotoxicity. Cytochrome P450 2J2 (CYP2J2) is a cytochrome P450 epoxygenase in human cardiomyocytes that converts arachidonic acid (AA) to cardioprotective epoxyeicosatrienoic acid (EET) regioisomers. Herein, we performed biochemical studies to understand the interaction of anthracycline derivatives (daunorubicin, doxorubicin, epirubicin, idarubicin, 5-iminodaunorubicin, zorubicin, valrubicin, and aclarubicin) with CYP2J2. We utilized fluorescence polarization (FP) to assess whether anthracyclines bind to CYP2J2. We found that aclarubicin bound the strongest to CYP2J2 despite it having large bulky groups. We determined that ebastine competitively inhibits anthracycline binding, suggesting that ebastine and anthracyclines may share the same binding site. Molecular dynamics and ensemble docking revealed electrostatic interactions between the anthracyclines and CYP2J2, contributing to binding stability. In particular, the glycosamine groups in anthracyclines are stabilized by binding to glutamate and aspartate residues in CYP2J2 forming salt bridge interactions. Furthermore, we used iterative ensemble docking schemes to gauge anthracycline influence on EET regioisomer production and anthracycline inhibition on AA metabolism. This was followed by experimental validation of CYP2J2-mediated metabolism of anthracycline derivatives using liquid chromatography tandem mass spectrometry fragmentation analysis and inhibition of CYP2J2-mediated AA metabolism by these derivatives. Taken together, we use both experimental and theoretical methodologies to unveil the interactions of anthracycline derivatives with CYP2J2. These studies will help identify alternative mechanisms of how anthracycline cardiotoxicity may be mediated through the inhibition of cardiac P450, which will aid in the design of new anthracycline derivatives with lower toxicity.

BACKGROUND: Amid the coronavirus disease 2019 (COVID-19) pandemic, dermatologists must be prepared to restructure their practice of procedural dermatology and cutaneous aesthetic surgeries. The COVID-19 pandemic has presented several challenges and has ushered in several changes in practice such as teledermatology, with many physicians adopting virtual consultations and treatments. Performing procedures in the times of COVID-19 pandemic presents challenges such as risk of transmission to doctors and staff due to potential aerosolization, release of virus droplets during the procedures, and risk of virus transfer through the instruments both in the peri- and postoperative period. This can have several medical, administrative, and legal implications. OBJECTIVES: This document aimed to outline best practices that can be followed in this scenario to perform cutaneous surgeries and procedures to ensure safer skin surgery. RECOMMENDATIONS: Standard precautions include social distancing of at least 1 m, hand hygiene, appropriate use of personal protective equipment (PPE), safe injection practices, sterilization and disinfection of medical devices, environmental cleaning, and respiratory hygiene. It is generally advisable to see patients only by appointments. Each clinic should have a special area at entry for screening patients and providing sanitizers and masks. Procedures, which are of short duration, performed on nonfacial areas are considered as low risk and require donning surgical mask. Procedures involved with minimal invasiveness and bleeding, short duration procedures on the face such as injectables, chemical peels, and aerosol-generating procedures on nonfacial areas are considered moderate risk. These procedures need apron with head cover, N95 mask, face shield, double gloves, and smoke evacuator with high-efficiency particulate air (HEPA) or ultralow particulate air (ULPA) filter. Aerosol and plume-regenerating procedures (such as ablative lasers on the face), prolonged surgeries on head (such as hair transplantation), intraoral, and intranasal procedures are considered high risk. These procedures must be carried out with full body cover with surgical gown, head cover, N95 mask, face shield, double gloves, and smoke evacuator. Physicians should be aware of local epidemiological situation and adhere to the relevant guidelines issued by the relevant governmental agencies.
ABSTRACT
The COVID-19 pandemic has taken the entire world by storm. Almost all dermatology laser procedures are considered non-essential and there is a consensus that they should be deferred till the threat of the COVID-19 is well and truly over. The article presents recommendations for the use of lasers and energy based devices in a safe manner during and in the immediate aftermath of COVID-19 pandemic. Plume generating procedures need full personal protective equipment to be used. Special precautions are required for specific laser and energy based procedures. A robust disinfection strategy based on preventing fomite borne COVID-19 transmission in the laser operating room is essential.
ABSTRACT
Background: Vitiligo is an acquired disorder characterized by depigmented macules or patches on the skin due to the loss of functional melanocytes. Segmental vitiligo (SV) is a subtype of vitiligo refractory to treatment. Objective: We studied safety and efficacy of 308-nm monochromatic excimer light (MEL) in combination with 0.1% tacrolimus ointment for the treatment of SV. Methods: Fifty patients with SV were enrolled. MEL was given on alternate dates in combination with topical tacrolimus. Clinical photographs were taken once a month. Two independent dermatologists analyzed and graded the results. Results: Five patients were lost to follow-up. Concerning overall treatment success, 77.8 percent of patients demonstrated at least 75-percent repigmentation. More specifically, 35.6 percent of patients showed complete (100%) repigmentation (Grade 5), whereas 42.2 percent of patients showed more than 75-percent repigmentation (Grade 4). Conclusion: Combination therapy with topical 0.1% tacrolimus and a 308-nm excimer lamp appears to be efficacious with a good safety profile. The duration of disease was a statistically significant factor inversely correlated with treatment success rate. The site of vitiligo also plays a significant part in the outcome, as facial lesions responded best to the treatment.
ABSTRACT
Melasma is a common acquired disorder of hyperpigmentation. A variety of treatment options has been suggested for the management of melasma. A range of different lasers had been tried in the treatment of melasma. Q-switched Nd-YAG laser (QSL) is the most commonly used laser in the treatment of melasma. Recently, laser toning or low-fluence, multi-pass technique has become popular in treatment of melasma. Authors aimed to review the procedure, its effectiveness, combination therapies using laser toning, and complications of laser toning. A PubMed search was made using keywords such as laser toning, QSL, melasma, and lasers in melasma, and relevant articles were reviewed.
