RESUMEN
BACKGROUND: There is a lack of literature of health-related quality of life endpoints for radial forearm (RF) versus anterolateral thigh (ALT) free flap reconstruction for glossectomy defects. Our goal was to perform a comprehensive evaluation of clinical, functional, and quality of life outcomes after glossectomy reconstruction using a RF or ALT flap. METHODS: A retrospective review was performed on patients who underwent glossectomy and immediate reconstruction with RF or ALT flaps between 2016 and 2021. Outcomes of interest included readmission and reoperation rates, functional assessments, tracheostomy and gastrostomy tube status, and FACE-Q Head and Neck Cancer scores. RESULTS: Seventy-eight patients consisting of 54 RF and 24 ALT free flaps were included. ALT patients had a larger median flap size (72 vs. 48 cm2 , p = 0.021) and underwent mandibulotomy (50% vs. 7.4%, p < 0.0001) and base of tongue resection (58.3% vs. 24.1%, p = 0.005) at higher rates. No significant differences were found with respect to other outcomes. CONCLUSION: The RF and ALT flaps are suitable for glossectomy reconstruction, with minimal differences seen in postoperative outcomes. Our study suggests that ALT can be used in patients with base of tongue and larger defect sizes, while providing similar functional and clinical outcomes to RF reconstruction.

Common risk factors for many ocular pathologies involve non-pathologic, age-related damage to the optic nerve. Understanding the mechanisms of age-related changes can facilitate targeted treatments for ocular pathologies that arise at any point in life. In this review, we examine these age-related, neurodegenerative changes in the optic nerve, contextualize these changes from the anatomic to the molecular level, and appreciate their relationship with ocular pathophysiology. From simple structural and mechanical changes at the optic nerve head (ONH), to epigenetic and biochemical alterations of tissue and the environment, multiple age-dependent mechanisms drive extracellular matrix (ECM) remodeling, retinal ganglion cell (RGC) loss, and lowered regenerative ability of respective axons. In conjunction, aging decreases the ability of myelin to preserve maximal conductivity, even with "successfully" regenerated axons. Glial cells, however, regeneratively overcompensate and result in a microenvironment that promotes RGC axonal death. Better elucidating optic nerve neurodegeneration remains of interest, specifically investigating human ECM, RGCs, axons, oligodendrocytes, and astrocytes; clarifying the exact processes of aged ocular connective tissue alterations and their ultrastructural impacts; and developing novel technologies and pharmacotherapies that target known genetic, biochemical, matrisome, and neuroinflammatory markers. Management models should account for age-related changes when addressing glaucoma, diabetic retinopathy, and other blinding diseases.

Background/Objective: The frequency of hematospermia in transgender women is unknown. This report aimed to describe the development of hematospermia in a transgender woman. Case Report: A 35-year-old transgender woman treated with estradiol valerate and leuprolide presented with painless rust-tinged ejaculate, urethral bleeding after ejaculation, and intermittent hematuria. Her medical history included gastroesophageal reflux disease, internal hemorrhoids, and attention deficit hyperactivity disorder with negative tobacco smoking and urologic history. Additional medications included emtricitabine-tenofovir disoproxil fumarate and fexofenadine. Physical examination did not reveal constitutional or genitourinary abnormalities. Urinalysis and culture disclosed rare white blood cells with gram-variable bacilli. The chlamydia, gonorrhea, and human immunodeficiency virus test results were negative. Abdominal computed tomography did not reveal bladder or prostate cancer, calcifications, inflammation, or cysts. She continued to have symptoms after this initial workup. One year after the initial symptom onset, transrectal ultrasound disclosed a 1.7-cm midline posterior prostatic cyst with hemorrhagic products, later revealed by magnetic resonance imaging as communicating with the left seminal vesicle. Two ultrasound-guided transperineal biopsy samples revealed benign prostatic tissue with a small focus of Müllerian or endometrial-type tissue, evidenced by immunopositivity for paired-box gene 8 and estrogen receptor in epithelium and cluster of differentiation 10 immunopositivity in stroma. After medical consultation, the patient underwent prostatic cyst aspiration, resection of the transurethral ejaculatory ducts, and orchiectomy. She did not experience any complications after these procedures. Discussion: The etiology of hematospermia may be idiopathic, iatrogenic, anatomic, or pathologic. Conclusion: Occult endometriosis or ectopic Müllerian epithelial tissue growth may occur in transgender women taking feminizing gender-affirming hormone therapy.
RESUMEN
Background/Objectives: To investigate macular vascular biomarkers for the detection of primary open-angle glaucoma (POAG). Methods: A total of 56 POAG patients and 94 non-glaucomatous controls underwent optical coherence tomography angiography (OCTA) assessment of macular vessel density (VD) in the superficial (SCP), and deep (DCP) capillary plexus, foveal avascular zone (FAZ) area, perimeter, VD, choriocapillaris and outer retina flow area. POAG patients were classified for severity based on the Glaucoma Staging System 2 of Brusini. ANCOVA comparisons adjusted for age, sex, race, hypertension, diabetes, and areas under the receiver operating characteristic curves (AUCs) for POAG/control differentiation were compared using the DeLong method. Results: Global, hemispheric, and quadrant SCP VD was significantly lower in POAG patients in the whole image, parafovea, and perifovea (p < 0.001). No significant differences were found between POAG and controls for DCP VD, FAZ parameters, and the retinal and choriocapillaris flow area (p > 0.05). SCP VD in the whole image and perifovea were significantly lower in POAG patients in stage 2 than stage 0 (p < 0.001). The AUCs of SCP VD in the whole image (0.86) and perifovea (0.84) were significantly higher than the AUCs of all DCP VD (p < 0.05), FAZ parameters (p < 0.001), and retinal (p < 0.001) and choriocapillaris flow areas (p < 0.05). Whole image SCP VD was similar to the AUC of the global retinal nerve fiber layer (RNFL) (AUC = 0.89, p = 0.53) and ganglion cell complex (GCC) thickness (AUC = 0.83, p = 0.42). Conclusions: SCP VD is lower with increasing functional damage in POAG patients. The AUC for SCP VD was similar to RNFL and GCC using clinical diagnosis as the reference standard.
RESUMEN
PRCIS: Capillary and neuronal tissue loss occur both globally and with regional specificity in pre-perimetric glaucoma patients at the level of the optic nerve and macula, with perifovea regions affected earlier than parafovea areas. PURPOSE: To investigate optic nerve head (ONH) and macular vessel densities (VD) and structural parameters assessed by optical coherence tomography angiography in pre-perimetric open angle glaucoma (ppOAG) patients and healthy controls. MATERIALS AND METHODS: In all, 113 healthy and 79 ppOAG patients underwent global and regional (hemispheric/quadrants) assessments of retinal, ONH, and macular vascularity and structure, including ONH parameters, retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thickness. Comparisons between outcomes in ppOAG and controls were adjusted for age, sex, race, BMI, diabetes, and hypertension, with P <0.05 considered statistically significant. RESULTS: In ppOAG compared with healthy controls: RNFL thicknesses were statistically significantly lower for all hemispheres, quadrants, and sectors ( P <0.001-0.041); whole image peripapillary all and small blood vessels VD were statistically significantly lower for all the quadrants ( P <0.001-0.002), except for the peripapillary small vessels in the temporal quadrant (ppOAG: 49.66 (8.40), healthy: 53.45 (4.04); P =0.843); GCC and inner and full macular thicknesses in the parafoveal and perifoveal regions were significantly lower in all the quadrants ( P =0.000- P =0.033); several macular VD were significantly lower ( P =0.006-0.034), with the exceptions of macular center, parafoveal superior and inferior quadrant, and perifoveal superior quadrant ( P >0.05). CONCLUSIONS: In ppOAG patients, VD biomarkers in both the macula and ONH, alongside RNFL, GCC, and macular thickness, were significantly reduced before detectable visual field loss with regional specificity. The most significant VD reduction detected was in the peripheric (perifovea) regions. Macular and ONH decrease in VD may serve as early biomarkers of glaucomatous disease.
