RESUMO
OBJECTIVE: To present a series of conjunctival keratoacanthomas and provide clinical, histopathological, immunohistochemical, and imaging results that characterize this rare entity. METHODS: A retrospective chart review of records from 2005 to 2023 from the Florida Lions Ocular Pathology Laboratory was conducted. Nine patients with histologically proven conjunctival keratoacanthoma were identified. Data extracted includes demographics, clinical history, diagnostic testing, histopathological and immunohistochemical testing, treatment modalities, and recurrences. RESULTS: Patients' mean age was 55.2 ± 21.1 years (range: 22-83). 77.8% (7/9) of patients were male. 55.6% (5/9) were Hispanic. 55.6% of lesions (5/9) were in right eyes. 55.6% of lesions (5/9) were on the temporal, bulbar conjunctiva. The lesions were rapidly growing, with mean onset time of 4.71 ± 3.30 weeks (range: 2-12). High-resolution anterior segment optical coherence tomography of three lesions revealed hyper-reflective, thickened epithelium with abrupt transition between normal and abnormal epithelium. Underlying disorganized subepithelial tissue was noted. However, the overlying abnormal epithelium caused considerable shadowing, which obscured subepithelial structures. Prominent, keratin-filled, cup-shaped lesions with faulty maturational sequencing that extend full thickness, variably pale cytoplasm, and foci of dyskeratosis and hyperkeratosis were present on all lesions' histopathology. All lesions were surgically excised, but two demonstrated partial spontaneous resolution before surgery. Two patients were lost to follow-up; the remaining seven had no signs of recurrence at a of mean of 36.9 ± 45.4 months (range: 3 to 141 months) of follow-up. CONCLUSIONS: Conjunctival keratoacanthomas are rare lesions of the ocular surface with distinct clinical, histopathologic, and diagnostic features.
RESUMO
Localized orbital amyloidosis is a rare clinical entity. Periocular and orbital amyloid deposits are mainly located at the lacrimal apparatus, eyelid, conjunctiva, ocular adnexa, extraocular muscles, and levator palpebrae muscle. In this article, we report an unusual case of optic nerve amyloid deposition in an 82-year-old African American woman who presented with vertical diplopia. MRI revealed an enhancing mass from the optic nerve sheath, and CT showed foci of calcifications suggestive of optic nerve meningioma. However, an incisional biopsy demonstrated lymphoproliferative disease with focal optic nerve sheath amyloid deposition confirmed by histologic Congo red staining and immunohistochemistry.
RESUMO
Purpose: Conjunctival melanoma is a rare neoplasm with high rates of recurrence and metastasis. Traditional management includes surgical excision and cryotherapy, followed by adjuvant therapy as needed. Immune checkpoint inhibitors, including nivolumab, are a targeted treatment option with improved survival rates. However, various immune-related adverse effects have been reported with these drugs. While systemic granulomatous inflammation is a documented systemic side effect, it has rarely been reported in the conjunctiva and ocular adnexa. Observation: A patient with a history of recurrent metastatic conjunctival melanoma presented with both a left sub-conjunctival and upper eyelid lesion after the commencement of treatment with nivolumab. The lesions were excised with a clinical suspicion for metastasis and consisted of noncaseating granulomatous inflammation with no evidence of malignancy on histopathologic examination. Infectious and primary autoimmune etiologies were ruled out. Conclusion and importance: This is a biopsy-proven case of periocular immune checkpoint inhibitor-associated granulomatous inflammation.
RESUMO
INTRODUCTION: Currently, there are limited accessible and cost-effective biomarkers for preclinical Alzheimer's disease (AD) patients. However, the apolipoprotein E (ApoE) polymorphic alleles can predict if someone is at high (e4), neutral (e3), or low (e2) genetic risk for developing AD. This study analyzed electroencephalogram (EEG) reports from individuals with various ApoE genotypes, aiming to identify EEG changes and patterns that could potentially serve as predictive markers for preclinical AD progression. METHODS: Participants aged 64-78 were selected from the patient database at an outpatient neurology clinic. Genotype studies were performed to determine ApoE status, followed by EEG analysis to identify any apparent trends. A case-control design was used, categorizing participants into cases (e2e3, e2e4, e3e4, e4e4) and controls (e3e3). EEG recordings were compared between the groups to identify potential differences in EEG characteristics, including abnormal temporal slowing, frequency, and ApoE genotype association. RESULTS: Among 43 participants, 49% demonstrated evidence of abnormal temporal slowing on EEG. Of these, 48% displayed focal left temporal slowing, and 52% displayed bilateral temporal slowing. The right-sided temporal slowing was not observed. Among participants with abnormal slowing, 95% exhibited theta frequency (4-8 Hz) slowing, while only 4.8% displayed delta frequency (0-4 Hz) slowing. Among participants with the ApoE4 allele, 61.5% demonstrated evidence of abnormal slowing, compared to 43.3% without it. Furthermore, the presence of an ApoE4 allele was associated with a significantly higher proportion of males (54%) compared to those without it (13%) (p=0.009). CONCLUSIONS: Although we did not find a statistically significant difference in temporal EEG slowing among different ApoE genotypes, our findings suggest a potential association between temporal slowing on EEG and the presence of an ApoE4 allele in individuals with preclinical AD. These observations highlight the need for further exploration into the potential influence of the ApoE4 allele on EEG findings and the utility of EEG as a complementary diagnostic tool for AD. Longitudinal studies with large sample sizes are needed to establish the precise relationship between EEG patterns, ApoE genotypes, and AD progression.
RESUMO
CONTEXT: Despite the association of advance care planning (ACP) with improved patient and caregiver outcomes, Chinese American elders have low rates of ACP. OBJECTIVES: Assess ACP facilitators/barriers in the San Francisco (SF) Chinese community and codesign, implement, and test community-based ACP-promoting pilot events. METHODS: A Chinese Community Committee (N = 19 community-based organization leaders, health system representatives, community members) conducted focus groups in Cantonese and English with Chinese older adults (age ≥55), caregivers, and community leaders. The Committee designed and implemented pilot events in-person and online. We analyzed focus group data using thematic analysis; assessed pre-to-post-event readiness to engage in ACP (validated survey; 14 scale, 4 = most ready); and assessed event acceptability. RESULTS: A total of 34 people participated in six focus groups. Themes described Chinese community-specific importance of ACP (e.g., reduces family burden), barriers (e.g., younger generations lack tools to discuss ACP with elders and vice versa), and facilitators (e.g., intergenerational events, culturally/linguistically appropriate materials). Based on focus groups findings, the Committee developed a novel ACP tool and designed intergenerational events. A total of 195 participants attended 10 events; 95% were Chinese, 90% spoke Chinese languages, 80% were women. ACP readiness increased significantly (1.66 [SD 0.84] vs. 2.03 [SD 0.85]; P < 0.001); 94% of participants were comfortable attending and 96% would recommend events. CONCLUSION: Community-developed intergenerational events that highlight the value of ACP and address barriers are acceptable and increase ACP engagement in the Chinese community.

Epstein-Barr virus is a known cause of dacryoadenitis that is typically sensitive to corticosteroid treatment. When affecting the orbit, particularly the lacrimal gland, Epstein-Barr virus may cause chronic proptosis and a bilateral lacrimal mass effect. We provide a case of bilateral Epstein-Barr virus associated dacryoadenitis initially resistant to corticosteroid treatment requiring biopsy and confirmation by polymerase chain reaction of lacrimal tissue. Herein, we discuss the presentation with associated magnetic resonance imaging and histopathologic images, diagnostic dilemma, and treatment of an atypical case.
RESUMO
BACKGROUND: People identifying as Black/African American are less likely to engage in advance care planning (ACP) compared to their White peers, despite the association of ACP with improved patient and caregiver outcomes. OBJECTIVES: Assess facilitators/barriers to ACP in the San Francisco (SF) Black community and co-design/implement/test community-based ACP pilot events. DESIGN: Community-based participatory research, including qualitative research, intervention development, and implementation. PARTICIPANTS: In partnership with the SF Palliative Care Workgroup (which includes health system, city, and community-based organizations), we formed an African American Advisory Committee (n = 13). We conducted 6 focus groups with Black older adults (age ≥ 55), caregivers, and community leaders (n = 29). The Advisory Committee then selected 5 community-based organizations through a widespread request for proposal. These community-based organizations designed and implemented community-based pilot events to support ACP engagement. MAIN MEASURES: Two authors analyzed recorded focus group transcripts using thematic analysis. We assessed pre- vs post-event readiness to engage in ACP (validated ACP Engagement Survey; 1-4 scale, 4 = most ready) using Wilcoxon signed rank tests and assessed event acceptability with open-ended questions. KEY RESULTS: Themes included the importance of ACP to the Black community (sub-themes: strengthens families; preserves dignity, particularly for sexual/gender minorities; is tied to financial planning) and facilitators for increasing ACP engagement (sub-themes: culturally relevant materials; events in trusted community spaces including Black-owned businesses). A total of 114 participants attended 5 events; 74% identified as Black, and 16% as sexual/gender minorities. Readiness to engage in ACP was similar pre- vs post-events; 98% would recommend the events to others. CONCLUSIONS: Community-based ACP events designed and led by and for the Black community are highly acceptable. Novel insights underscored the importance of financial planning as part of ACP and the role of Black-owned businesses as trusted spaces for ACP-related discussions.

BACKGROUND: Advance care planning (ACP) is low among Latinx older adults. We used community-based participatory research (CBPR) to identify ACP barriers/facilitators and design community-based ACP events. METHODS: In partnership with community-based organizations, clinicians, and local government, we formed a Latinx Community Committee (n = 13 community members). We then conducted 6 focus groups with Latinx-identifying, English or Spanish-speaking older adults (age ≥ 55), caregivers, and community leaders to assess ACP barriers/facilitators. We analyzed transcripts using thematic analysis and, based on these learnings, designed and implemented community-based ACP events. Using a validated survey, we assessed acceptability and pre-to-post-event ACP readiness (4-point scale; 4 = most ready; 0.2 change considered meaningful) with Wilcoxon signed-rank tests. RESULTS: Focus groups included 10 Spanish-speaking older adults, 8 caregivers, and 10 community leaders. Themes highlighted the importance of ACP (e.g., means of advocacy), barriers (e.g., how to start conversations), and facilitators (e.g., trusted community spaces) in the Latinx community. Ninety-seven people attended 5 events targeting 3 Latinx populations (LGBTQI+, intergenerational, and older adults broadly). Overall pre-to-post-event ACP readiness increased (2.62 (SD 0.97) to 2.95 (SD 0.93); p = 0.05). Readiness to document wishes increased significantly (2.44 (SD 1.0) to 2.98 (SD 0.95); p = 0.003). Most reported being comfortable attending events (85%) and would recommend them to others (90%). CONCLUSIONS: This study describes a feasible, acceptable, and effective CBPR ACP intervention. Co-developed community events represent a promising approach to reducing disparities in ACP among the Latinx population.

Importance: Many patients seen for eye-related issues in the emergency department do not receive recommended follow-up care. Prior evidence supports that scheduling appointments is a barrier to accomplishing the transition to outpatient ophthalmology care. Objective: To evaluate time until appointment scheduling following emergency department discharge with urgent outpatient ophthalmology referral. Design, Setting, and Participants: The A3 problem solving process was implemented by a multidisciplinary team as part of a structured quality improvement program with the goal of reducing the mean time between urgent referral placement in the emergency department and outpatient ophthalmology appointment scheduling. The study was conducted at Stanford Health Care, an academic medical center in Palo Alto, California, affiliated with Stanford University School of Medicine. Using medical center administrative records, all patients discharged from the adult emergency department with an urgent outpatient referral to the Stanford Department of Ophthalmology from August 9 to September 19, 2020 (baseline; n = 43), and from October 26 to November 29, 2020 (after implementation of all interventions; n = 21), were included. Interventions: Interventions developed to target the workflow of the ophthalmology resident, emergency department, ophthalmology clinic, and health system schedulers to address key drivers of the referral-scheduling process included medical record documentation guidelines, identification of responsible parties, preidentified appointment slots, patient education materials, and education of stakeholders, and were implemented by October 25, 2020. Main Outcomes and Measures: Mean time between urgent referral placement (ie, emergency department discharge) and appointment scheduling with outpatient ophthalmology at baseline vs postintervention. Results: At baseline, appointments were scheduled a mean (range) 2.8 (0-7) days after referral placement. In the 5 weeks following implementation of interventions, the mean (range) decreased to 1.3 (0-4) days, a difference of 1.5 days (95% CI, 0.20-2.74; P = .02). This corresponds to 642 (95% CI, 86-1173) days of reduced patient wait time annually. In addition, there was less variability in the number of days between referral and appointment scheduling after intervention compared with baseline. Conclusions and Relevance: The results suggest improvement in efficiency of outpatient ophthalmology appointment scheduling of urgent emergency department referrals could be achieved through application of a quality improvement methodology by a multidisciplinary team representing key stakeholders in the process.

INTRODUCTION: Against the backdrop of the diverse minority-majority state of Hawaii, this study seeks to better characterize associations between idiopathic intracranial hypertension (IIH) with sociodemographic variables and medical comorbidities. METHODS: A retrospective case-control study was conducted by utilizing 54 IIH patients and 216 age-, sex-, and race-matched controls, 216 unmatched controls, and 63 age-, sex-, and race-matched migraine patients. RESULTS: Relative to controls, IIH were 25 years younger (p < 0.0001) and 10.18 kg/m2 heavier (p < 0.0001), as well as exhibited greater odds of the following variables (p < 0.05): female (odds ratio [OR]: 8.87), the lowest income quartile (OR: 2.33), Native Hawaiian or other Pacific Islander (NHPI; OR: 2.23), Native American or Alaskan Native (OR: 16.50), obesity class 2 (35.0-39.9 kg/m2; OR: 4.10), obesity class 3 (>40 kg/m2; OR: 6.10), recent weight gain (OR: 11.66), current smoker (OR: 2.48), hypertensive (OR: 3.08), and peripheral vascular disease (OR: 16.42). Odds of IIH were reduced (p < 0.05) for patients who were Asian (OR: 0.27) or students (OR: 0.30;). Unique from Whites, NHPI IIH patients exhibited greater odds (p < 0.05) for being from lower socioeconomic status and currently smoking, as well as potential association with seizures (p = 0.08). Compared to migraines, IIH headaches were at increased odds of occurring (p < 0.05) occipitally, for greater than 15 days per month, aggravated by postural changes, and comorbid with dizziness and tinnitus. CONCLUSIONS: These results not only better characterize IIH, but also highlight socioeconomic and racial disparities in diagnosis.

BACKGROUND: Suctioning is an integral component of care for patients who are intubated and ventilated in an intensive care unit (ICU). There appears to be no published data of physiotherapy suctioning practices in Australia or New Zealand. OBJECTIVE: To describe suctioning practices and the factors which have shaped these practices, of experienced physiotherapists working with adults who are intubated and ventilated in an ICU across Australia and New Zealand. Areas of investigation focused on: (i) suctioning approach (i.e. open vs. closed system); (ii) use of adjuncts to suctioning such as hyperoxygenation, hyperinflation and saline lavage; (iii) use of subglottic suctioning and; (iv) factors influencing suctioning practices. METHODS: Electronic surveys were emailed to experienced physiotherapists working in ICUs across Australia and New Zealand which had the capacity to intubate and ventilate adult patients for ≥24h. RESULTS: The participation rate was 84.8% (112/132). Closed suction system was used in most ICUs (97/112, 86.6%). Hyperoxygenation was commonly performed on 'all' or 'most' patients before suctioning (71/112, 63.4%), but less frequently after suctioning (38/112, 33.9%). Hyperinflation was infrequently performed on 'all' or 'most' patients before (22/112, 19.6%) or after suctioning (22/112, 19.6%). Saline lavage and subglottic suctioning were infrequently performed on 'all' or 'most' patients (3/112, 2.7%; 17/112, 15.2%, respectively). 'Personal experience' and 'established practice in the ICU' had the greatest influence on suctioning practices. CONCLUSIONS: Most ICUs in Australia and New Zealand are equipped for closed system suctioning. As hyperoxygenation minimises desaturation during suctioning, there may be scope for a larger proportion of physiotherapists to use this adjunct. The practice of hyperinflation before and after suctioning was uncommon despite the emerging evidence for improved lung compliance with this procedure. Subglottic suctioning was infrequently available as a choice for physiotherapists despite the strong evidence, which suggests an evidence-practice gap.
