RESUMO

BACKGROUND: Cataract is the leading cause of avoidable blindness globally. This study aims to measure the changes in Vision function-related quality of life (VFQoL) before and after cataract surgery and identify the predictors of an improvement in these outcomes. METHODS: A multicenter, longitudinal cohort study was conducted. Patients with first eye cataracts were interviewed before and 6 months after cataract surgery. Multiple classification analysis (MCA) was performed to assess variation in the intensities of mean change scores for general function, psychosocial impact, and visual function with select factors. RESULTS: A total of 747 participated in the baseline assessment. The 6-month follow-up rate was 86.5%. The mean general function, psychosocial impact, and visual function scores were 35.3 (±8.6), 12.5 (±3.4), and 8.3 (±3) in the baseline and 17 (±5.3), 6 (±2.2) and 3.8 (±1.3) in the follow-up assessments, respectively. In MCA, patients using spectacles postsurgery (ß 0.111) and those having a very good postoperative visual acuity (ß 0.098) had the most impact on general function. Patients reporting no ocular complaints postsurgery had a relatively higher effect on the psychosocial impact, (ß 0.168) and similarly, patients using spectacles postsurgery and those aged 70 and older had the most impact on the visual function scores (ß 0.146 and 0.126), respectively. CONCLUSION: Cataract surgery is associated with meaningful improvements in vision and VFQoL in general. The determinants of better VFQoL include the usage of spectacles postsurgery. Strategies to further improve patient participation in postoperative review visits are needed for spectacle provision and patient education regarding spectacle use and compliance is imparted during such visits.

RESUMO

CONTEXT.­: The College of American Pathologists (CAP) surveys provide national benchmarks of pathology practice. OBJECTIVE.­: To investigate pancreaticobiliary cytology practice in domestic and international laboratories in 2021. DESIGN.­: We analyzed data from the CAP Pancreaticobiliary Cytology Practice Supplemental Questionnaire that was distributed to laboratories participating in the 2021 CAP Nongynecologic Cytopathology Education Program. RESULTS.­: Ninety-three percent (567 of 612) of respondent laboratories routinely evaluated pancreaticobiliary cytology specimens. Biliary brushing (85%) was the most common pancreaticobiliary cytology specimen evaluated, followed by pancreatic fine-needle aspiration (79%). The most used sampling methods reported by 235 laboratories were 22-gauge needle for fine-needle aspiration (62%) and SharkCore needle for fine-needle biopsy (27%). Cell block was the most used slide preparation method (76%), followed by liquid-based cytology (59%) for pancreatic cystic lesions. Up to 95% (303 of 320) of laboratories performed rapid on-site evaluation (ROSE) on pancreatic solid lesions, while 56% (180 of 320) performed ROSE for cystic lesions. Thirty-six percent (193 of 530) of laboratories used the Papanicolaou Society of Cytopathology System for Reporting Pancreaticobiliary Cytology in 2021. Among all institution types, significant differences in specimen volume, specimen type, ROSE practice, and case sign-out were identified. Additionally, significant differences in specimen type, slide preparation, and ROSE practice were found. CONCLUSIONS.­: This is the first survey from the CAP to investigate pancreaticobiliary cytology practice. The findings reveal significant differences among institution types and between domestic and international laboratories. These data provide a baseline for future studies in a variety of practice settings.

RESUMO

Purpose: Data on social-emotional aspects among children with strabismus in India are scanty. We compared the emotional symptoms (ES), loneliness and social dissatisfaction (LSD), and self-esteem (SE) and their associated risk factors among children with and without strabismus in India. Methods: A cross-sectional case-control study design was used to recruit 101 children with strabismus aged 8 to 18 years and a control group of 101 children that were age- and gender-matched. Interviews were performed using standardized scales to assess ES, LSD, and SE. Variations in the intensity of ES, LSD, and SE were assessed using multiple classification analysis (MCA). Results: A total of 202 children participated in the study. The mean ES, LSD, and SE scores were 3.4 (standard deviation [SD] 1.9), 48.4 (SD 3.2), and 22.1 (SD 3.8) for the strabismus group and 1.8 (SD 1.5), 33.3 (SD 3), and 31.3 (SD 2) for the non-strabismus group, respectively. Among the strabismus group, the highest levels of mean ES, LSD, and SE scores were observed among children facing problems in performing daily tasks. Amongst the non-strabismus group, children studying at the primary level and those facing neglect had the highest mean scores. In MCA, being affected with strabismus had the highest effect on the intensity of ES, LSD, and SE with a beta (ß) value of 0.223 (P = 0.016), 0.922 (P < 0.001), and 0.853 (P < 0.001). Conclusion: A significantly high proportion of children with strabismus deal with elevated levels of ES, LSD problems, and low SE as compared with non-strabismus children, highlighting the need to address the poor social-emotional health of children.

RESUMO

ABSTRACT: Hibernomas are "pseudolipomas" originating from remnants of fetal brown adipose tissue. These rare benign tumors may occur throughout the body but most commonly in the thigh, shoulder, back, and neck, and are rarely found in the abdominal cavity, retroperitoneum, breast, bones, scrotum, and perirectum. We present a case of a 58-year-old woman with a known mediastinal mass, who was incidentally found to have a very FDG-avid fat-containing lesion in the omentum abutting the stomach. Subsequent endoscopic ultrasound-guided fine-needle aspiration confirmed hibernoma. The review of the literature shows the location is very unusual.

RESUMO

Background: Systematic data on mental health issues among adults with cataracts are not available from India. This study explored the impact of cataract surgery on depressive and generalized anxiety (GA) symptoms in an adult Indian sample. Methods: A multicenter, prospective, longitudinal cohort study was conducted. Subjects were recruited from four tertiary eye hospitals to assess depression, GA, and associated risk factors. A follow-up survey was carried out at 6 (n = 273, group 1), 12 (n = 198, group 2), or 18 months (n = 105, group 3) post-cataract surgery. Variations in the intensity of depression and GA were assessed using multiple classification analysis (MCA). Results: A total of 576 patients completed both baseline and follow-up assessments. The mean (SD) depression score was 25.6 (8.5) before surgery and 8.6 (7.7), 9.9 (7), and 9.8 (6.8), respectively, post-surgery for the three groups on the Center for Epidemiologic Studies Depression scale (CES-D). The mean GA score was 6.7 (4.2) at baseline and 1.1 (2.3), 1 (1.8), and 0.6 (1.3) after surgery on the Generalized Anxiety Disorder scale (GAD-7). MCA showed that factors with the highest impact on the mean change scores for both depressive and GA symptoms were restoration of vision post-surgery (ß = 0.381 and 0.185) in group 1, regaining functional independence and female sex in group 2 (ß = 0.192 and 0.23), and the presence of ocular comorbidities in the fellow eye (ß = 0.36 and 0.315) in group 3. Conclusion: Mental health symptoms improved significantly post-cataract surgery across the three groups. The urgent need to invest in strategies that enable early cataract case detection and treat ocular anomalies in the fellow eye is highlighted.

RESUMO

PURPOSE: Lung nodules are a common radiographic finding. Non-surgical biopsy is recommended in patients with moderate or high pretest probability for malignancy. Shape-sensing robotic-assisted bronchoscopy (ssRAB) combined with radial endobronchial ultrasound (r-EBUS) and cone beam computed tomography (CBCT) is a new approach to sample pulmonary lesions. Limited data are available regarding the diagnostic accuracy of combined ssRAB with r-EBUS and CBCT. METHODS: We conducted a retrospective analysis of the first 200 biopsy procedures of 209 lung lesions using ssRAB, r-EBUS, and CBCT at UT Southwestern Medical Center in Dallas, Texas. Outcomes were based on pathology interpretations of samples taken during ssRAB, clinical and radiographic follow-up, and/or additional sampling. RESULTS: The mean largest lesion dimension was 22.6 ± 13.3 mm with a median of 19 mm (range 7 to 73 mm). The prevalence of malignancy in our data was 64.1%. The diagnostic accuracy of ssRAB combined with advanced imaging was 91.4% (CI 86.7-94.8%). Sensitivity was 87.3% (CI 80.5-92.4%) with a specificity of 98.7% (CI 92.8-100%). The negative and positive predictive values were 81.3% and 99.2%. The rate of non-diagnostic sampling was 11% (23/209 samples). The only complication was pneumothorax in 1% (2/200 procedures), with 0.5% requiring a chest tube. CONCLUSION: Our results of the combined use of ssRAB with r-EBUS and CBCT to sample pulmonary lesions suggest a high diagnostic accuracy for malignant lesions with reasonably high sensitivity and negative predictive values. The procedure is safe with a low rate of complications.

RESUMO

INTRODUCTION: In patients with a history of malignancy, follow-up surveillance of lymph nodes (LNs) is required to evaluate for potential malignancy or infection. In some cases, the lymphadenopathy may be secondary to an intraprocedural hemostatic agent and/or related granulomatous reaction. CASE PRESENTATION: We present the case of an 80-year-old female with a remote past medical history of breast cancer status post-lumpectomy and chemoradiation. Twenty years later, a 2.4 cm pulmonary right middle lobe nodule was noted on imaging studies. She underwent bronchoscopy, cervical mediastinoscopy, and right middle lobe wedge resection. The final pathologic diagnosis was a pulmonary carcinoid tumor, and the excised mediastinal LN was negative for malignancy. A 10-month surveillance positron emission tomography scan showed new mildly avid mediastinal and right hilar LNs. The following endobronchial ultrasound-guided transbronchial needle aspiration showed unremarkable lymphoid elements in the enlarged 4R LN, while the station 7 LN demonstrated ample dense hyaline-like foreign material. Subsequent review of the cell block/biopsy and communication with the thoracic surgeon revealed that Surgicel® (or oxidized regenerated cellulose) was placed during surgery at the station 7 site. DISCUSSION/CONCLUSION: Assessment of the findings and based on the similar histologic appearance reported in previous cases associated with Surgicel® [Ann Thorac Med. 2017;12(1):55-6, Cancer Cytopathol. 2019;127(12):765-70, and Arch Bronconeumol. 2020;56(7):459-71], the station 7 acellular, amorphous, and hyaline-like exogenous material found in our case was interpreted as hemostatic agent compatible with Surgicel® (or oxidized regenerated cellulose). This case highlights the importance of cytologic/histologic recognition of hemostatic agents, specifically oxidized cellulose mesh.

RESUMO

Background Systematic data on mental health issues among adults awaiting cataract treatment are not readily available in India. We explored the prevalence and predictors of depressive and generalized anxiety (GA) symptoms in a cohort of adults awaiting cataract surgery. Methods Our study is based on data from baseline assessments which were conducted as part of a multicentre prospective, longitudinal cohort study. Subjects were recruited from four eye hospitals to assess depression and GA and associated risk factors using standardized scales, i.e. Center for Epidemiologic Studies-Depression Scale (CES-D) and Generalised Anxiety Disorder (GAD-7). Variation in the intensity of depression and GA was assessed using multiple classification analysis (MCA). Results A total of 813 adults awaiting cataract surgery participated, of whom 456 (56.1%) were men. The mean (SD) CES-D and GAD-7 scores were 24.6 (7.8) and 6.3 (SD 4.2) for men and 25.8 (8.9) and 6.9 (4.4) for women, respectively. The overall prevalence of depression score of >16 was 87.4% (95% confidence interval [CI] 84.7%- 89.6%), and GA score of >10 was 57.1% (95% CI 53.5%-60.7%). The prevalence of comorbid depressive and anxiety symptoms was 56.6% (95% CI 52.9%- 60.2%). MCA showed that being neglected and mistreated by family/friends because of vision condition and facing difficulty and requiring help with daily tasks had the highest effect on the intensity of both depression (beta=0.254 and 0.238, respectively) and GA (beta=0.219 and 0.211, respectively). Conclusion The majority of adults with untreated cataract had both depressive and GA symptoms. These findings could be used for planning mental health interventions for adults awaiting cataract surgery.

RESUMO

Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous population of neoplasms that arise from hormone-secreting islet cells of the pancreas and have increased markedly in incidence over the past four decades. Non-functional PanNETs, which occur more frequently than hormone-secreting tumors, are often not diagnosed until later stages of tumor development and have poorer prognoses. Development of successful therapeutics for PanNETs has been slow, partially due to a lack of diverse animal models for pre-clinical testing. Here, we report development of an inducible, conditional mouse model of PanNETs by using a bi-transgenic system for regulated expression of the aberrant activator of Cdk5, p25, specifically in ß-islet cells. This model produces a heterogeneous population of PanNETs that includes a subgroup of well-differentiated, non-functional tumors. Production of these tumors demonstrates the causative potential of aberrantly active Cdk5 for generation of PanNETs. Further, we show that human PanNETs express Cdk5 pathway components, are dependent on Cdk5 for growth, and share genetic and transcriptional overlap with the INS-p25OE model. The utility of this model is enhanced by the ability to form tumor-derived allografts. This new model of PanNETs will facilitate molecular delineation of Cdk5-dependent PanNETs and the development of new targeted therapeutics.

RESUMO

Sinonasal malignant mucosal melanoma (SNM) is a rare, aggressive malignancy. The diagnosis of SNM is often quite challenging due to anatomical limitations, frequent lack of pigmentation, variable histologic appearances, and aberrant differentiation (e.g., positivity for cytokeratin, desmin, or neuroendocrine markers). S100 protein is routinely used as a standard screening marker for SNM, but it may lack optimal sensitivity. Our objective was to study the extent of immunohistochemical expression of S100 protein in SNM, and determine its diagnostic value by comparing it to a newer melanoma marker, SOX10. Twenty-three cases of sinonasal MMM were retrieved from the archival files of the Department of Pathology at UT Southwestern Medical Center. The patients included 14 men and 9 women, and ranged from 36 to 90 years (mean 64.9 years). Sections from blocks of formalin-fixed, paraffin-embedded tissue were used for immunohistochemical analysis with S100 protein and SOX10. The extent and intensity of immunostaining was recorded, and H-score was calculated. For a subset of negative or focally positive cases, S100 protein was repeated at a high-volume reference laboratory. S100 protein immunoexpression was quite variable in the SNM cases, with H-scores ranging from 0 to 300 (mean 123). While 11 of 23 cases exhibited strong and diffuse staining (H-score > 100) as expected for melanoma, 7 were weak and/or focal (H-score 1-100), and 5 were completely S100 protein-negative. For 10 cases, the negative or focal results were confirmed by reference laboratory staining. In contrast, all 23 SNM cases were diffusely and strongly positive for SOX10 (H-scores 210-300, mean 296). Our study demonstrated that S100 protein immunoexpression is extremely variable in SNM. Weak or even absent S100 protein staining is not uncommon in SNM, and should not dissuade pathologists from that diagnosis. Our data demonstrates that S100 protein is insufficiently sensitive to be used as a screening marker for SNM, but that SOX10 is consistently and robustly positive, and should therefore replace S100 protein for that purpose. Indeed, for any high-grade sinonasal tumor, pathologists must have a low threshold for utilizing additional markers to exclude the possibility of SNM.

RESUMO

Tumor-associated lymphoid proliferation (TALP) is a well-recognized lymphocytic reaction that is commonly associated with certain salivary gland tumors. A salivary carcinoma with TALP may be confused for true lymph node involvement by that tumor, constituting a potential pitfall in tumor staging that may result in unnecessary therapeutic intervention or erroneous prognostication for patients. True lymph nodes harbor populations of extrafollicular reticulum cells (ERCs), which can be highlighted by low molecular weight cytokeratin immunohistochemistry. We sought to determine whether low molecular weight cytokeratin Cam5.2 immunostaining may be utilized to differentiate true lymph node involvement by salivary gland tumors from TALP. The surgical pathology archives of the University of Texas Southwestern Medical Center was searched for cases of salivary gland neoplasms exhibiting either TALP or true lymph node involvement. Hematoxylin and eosin-stained sections were examined. Cases were classified on the basis of a definitive lymph node capsule and subcapsular sinus, as seen on routine histologic evaluation. Low molecular weight cytokeratin Cam5.2 immunostaining was performed and evaluated on all cases. Twenty-three salivary gland carcinomas with TALP and 16 carcinomas involving a lymph node (14 carcinomas metastatic to regional lymph nodes and 2 carcinomas arising from benign lymph node inclusions) were identified. Numerous Cam5.2-positive ERCs were identified within the nodal tissue of all true lymph nodes involved by carcinoma (16 of 16 cases), while Cam5.2-positive ERCs were completely absent in all cases of salivary gland lesions with TALP (0 of 23 cases) (100% vs. 0%, p < .0001, Fisher's Exact). Utilization of low molecular weight cytokeratin Cam 5.2 immunostaining for ERCs is a highly useful tool for distinguishing true lymph node involvement by salivary gland carcinomas from TALP. This strategy may be useful in identifying genuine nodal metastasis in histologically ambiguous cases, and to avoid erroneously upstaging tumor with TALP as nodal metastasis with the resulting prognostic and therapeutic implications. Moreover, low molecular weight cytokeratin immunostaining may be useful in confirming the rare examples of salivary gland tumors arising from intranodal salivary gland inclusions.

RESUMO

Purpose: Primary eye care services delivered through vision centres (VC) form an essential part of the national blindness control efforts, but systematic data on the outputs and cost of providing such services in India are not readily available for further planning and efficient use of resources.Methods: Detailed cost and output data were collected from written records for 2017-2018 fiscal year using standardized methods at nine VC in Kolkata city in West Bengal, India. The total economic cost for these VC was computed and the relation of unit cost of services per patient screened with VC scale was assessed using regression analysis. Break-even point was estimated from average and marginal cost functions.Results: 25,009 patients were screened at the 9 VC (range 709-5,717; median 2,826). The overall total economic cost was INR 7,304,172 (USD 113,306), ranging from INR. 509,618 (USD. 7,905) to INR. 1,390,855 (USD. 21,576). Personnel salaries made up 37.8% of the total cost. The unit economic cost of screening a patient was INR 292.1 (USD 4.4) and varied threefold between 9 VC. With a multiple regression model (p < .035, R2 = 0.797), apart from the fixed costs, the incremental cost for each patient screened was INR 81.33 (USD 1.26). Break-even analysis suggested that 44.4% of the VCs were functioning below optimal scale.Conclusion: A further reduction in the unit costs is possible if the optimal scale of services is achieved. These findings can inform resource requirement for the primary eye care services in India.

RESUMO

Purpose: Reliable data on the barriers to the uptake of cataract surgical services in the Northeast Indian states are scanty. The purpose of this study was to assess the barriers to uptake of cataract surgical services among elderly patients and suggest appropriate strategies to reduce these. Methods: A cross-sectional study was conducted among patients who failed to avail cataract surgical services, 6-12 months' postinitial diagnosis at a community eye health camp. Validated questionnaire was used to collect information through face-to-face interviews at the residence of the participants. Descriptive statistics and Chi-square tests were conducted to assess the association between the barriers quoted and sociodemographic variables. Results: A total of 140 (89.2%) individuals participated in the study, of whom 56 (40%) were aged between 71 and 80 years. The median age for men and women was 73.5 and 72.5 years, respectively. About 57% of participants were female patients. A total of 66 (47.1%) participants had borderline visual acuity followed by those with poor vision (41.4%, n = 58). "Bad roads/difficult terrain" (P = 0.009), "witnessed bad surgical outcomes in others" and "did not feel important" (P < 0.024), "poor overall health status" (P < 0.001), "lack of information" (P = 0.025) and "no escort" (P = 0.025) were significant barriers reported by this population. Conclusion: Most of the barriers reported in this study seem to be endogenous in nature and appear to be within the purview of the local eye care service provider to remedy. Counseling and targeted awareness and information, education, and communication strategies could nullify many of the barriers reported in this study.

RESUMO

BACKGROUND: Fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) scan is an indicator of potential malignancy or infection. Patients with a history of talc pleurodesis can develop pleural or lung parenchymal nodules/talcomas. In these patients, talc-associated (non-malignancy-related) FDG uptake may occur over years. CASE REPORT: A 66-year-old female presented with a past medical history significant for resected non-small-cell lung cancer and was treated with chemotherapy/radiation. The referring physician indicated that she subsequently developed benign pleural effusions and had talc pleurodesis to limit recurrence. The patient was referred to our institution for endobronchial ultrasound-guided transbronchial fine-needle aspiration (EBUS-TBNA) due to a new left upper lobe nodule with increasing FDG uptake on follow-up interval PET performed at the referring institution. On-site cytologic evaluation showed no evidence of malignancy, but found refractile foreign material, consistent with the presence of talc particles. CONCLUSION: This case presents the importance of cytologic recognition of talc particles during on-site evaluation and discusses the phenomenon of increasing PET-FDG uptake associated with talc pleurodesis.

RESUMO

The Insulin-like Growth Factor 1 (IGF1) gene is a member of somatotropic axis and plays a key role in proliferation of cells, mitosis, myogenesis, meiosis, differentiation in foetal development and post natal growth. The objectives of this study were to verify the single nucleotide polymorphisms (SNPs) in IGF1 gene and their association with growth traits in two indigenous native goat genetic groups of Kerala, viz., Malabari and Attappady Black. A total of 277 goats were genotyped using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using the restriction enzyme Cac8I. One SNP, A224G was detected in the 5' non-coding region of the IGF1 gene, and accordingly two genotypes were revealed, GG and AG. This SNP was significantly associated with growth traits in Attappady Black goats, which is maintained as meat breed in Kerala. Results from this study demonstrated higher performance of GG animals for growth traits. The association of IGF1 gene with these traits emphasizes the importance of caprine IGF1 as a candidate gene for growth traits in goat breeding.

RESUMO

Extramedullary hematopoiesis (EMH) is the trilineage formation of normal blood cells outside of the bone marrow. While predominantly seen in the spleen and liver, EMH rarely occurs in serous effusions. Accurate diagnosis requires recognition of megakaryocytes and other precursor hematopoietic elements. We present a case of pleural fluid EMH in a patient with primary myelofibrosis and developing leukemia, with a review of the literature, prognostic implications and diagnostic challenges.

Lymphangioleiomyomatosis (LAM) is a rare lung disease traditionally affecting women during their childbearing years. It can be sporadic or be associated with tuberous sclerosis syndrome. It is usually manifested in the lungs, kidneys, and/or lymphatic system. It consists of an overgrowth of abnormal smooth muscle-like cells, usually along the bronchovascular structures, resulting in the formation of cysts and the destruction of the lung parenchyma. We present the case of a 43-year-old woman with a history of pleural effusion and dyspnea. A computed tomographic scan revealed a mediastinal mass, chylothorax, and multiple pulmonary cysts. A diagnosis of LAM was rendered on a pleural fluid sample.
