Trichiasis removal using dermatological punch: A case report.

Entropion, a common malposition of the eyelid, can lead to trichiasis and corneal damage. This article presents a clinical case in which, following initial surgery to correct entropion, the use of a dermatological punch was chosen to definitively eliminate persistent trichiasis. This relatively unknown yet effective approach proved to be a quick and straightforward alternative with positive outcomes, emphasizing the importance of considering innovative approaches to recurrent challenges in clinical practice.

Structure and morphology of red pigments based on sepiolite.

Sepiolite is an important raw fibrous material. A method to prepare red pigments based on sepiolite through the thermal treatment of sepiolite with sulfur and sodium sulfide hydrate is reported. Sepiolite was heated until 800 °C in order to remove zeolitic water, the first coordinated water, the second coordinated water, and structural hydroxyls. Several [S/Na2S]molar ratios in the range 0.5-7 were employed. The properties of these pigments were studied by different analytical techniques, such as colorimetric analysis, thermal analysis, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction and scanning electron microscopy. The samples with [S/Na2S] = 0.5 and 1, corresponding to high contents of sodium sulfide in the synthesis procedure, exhibit high values of the colorimetric parameter CIE a* and a maximum reflectance in the visible zone belonging to red, based on the red colour of the samples. Under the reducing conditions of the synthesis, sulfur forms polysulfides of the general formula [Sx]2-. The sodium sulfide reacts with the excess S to form polysulfides as well. From the polysulfides, the radical anions of the general formula [Sx/2]˙- originate and they are identified as the chromophore groups responsible for the color in the sulfur-based pigment analogues of ultramarines. The red colour of the samples could be mainly attributed to the presence of S4 and S4˙- identified by FTIR.

Orbital myositis in a patient with Crohn's disease: A case report of two episodes.

PURPOSE: To describe a case report of a 34 years-old patient with Crohn's Disease and two episodes of Ocular Myositis. METHODS: The research methodology employed in this study consisted of a retrospective review of the patient's complete medical history. RESULTS: Crohn's Disease is a chronic inflammatory bowel disorder known to be associated with a wide range of extraintestinal manifestations. Ocular abnormalities, such as episcleritis and uveitis, are commonly observed. However, orbital myositis is an extremely rare ocular extraintestinal manifestations characterized by acute ocular pain that worsens with eye movements and is often accompanied by diplopia. In this case report, we present the case of a 34-year-old woman with a confirmed diagnosis of Crohn's Disease, who experienced two episodes of acute orbital pain exacerbated by ocular movements and diplopia. The diagnosis was established through clinical evaluation and radiologic imaging, with confirmation after a good response to systemic corticosteroids. She responded favorably to systemic corticosteroid therapy on both episodes, and no additional treatment was required. As of now, she remains stable without any ocular sequelae. CONCLUSION: It is important to note that orbital myositis is an uncommon ocular manifestation associated with Crohn's Disease, and prompt recognition and management are crucial to achieve successful outcomes.

Functional inferior canalicular reconstruction using a monocanalicular probe after tumor resection of the medial third of the lower eyelid.

PURPOSE: To describe a surgical technique for functionally reconstructing a lacrimal drainage duct and to assess its long-term functionality. METHODS: This observational review includes six cases involving reconstruction of the inferior canaliculus after surgical resection of lower eyelid carcinoma. Following lesion excision with safety margins, the epithelium of the distal portion of the inferior canaliculus is located and intubated with a monocanalicular probe. Subsequently, the eyelid lamellae are reconstructed without displacing the probe. The Monoka collarette is then sutured using a 10/0 nylon suture. Data collection included anatomic pathology of the lesion and data from ophthalmic examinations at each visit (including epiphora, inferior canalicular irrigation, and fluorescein dye disappearance test [FDDT]), as well as stent extrusion or other complications. RESULTS: No complications were observed during the surgeries. The stents remained in place for an average of 4months, with no extrusions prior to removal. The mean follow-up period was 4.8years (SD=2.0), during which no other complications were noted. Only one patient experienced intermittent epiphora, also present in the fellow eye. At the final visit, FDDT was normal in all eyes, and all patients demonstrated patency of the inferior canaliculus upon irrigation. CONCLUSION: Primary reconstruction of an inferior lacrimal drainage duct following tumor resection can be successfully performed, resulting in favorable functional recovery.

Cancer-Associated Thrombotic Microangiopathy: Literature Review and Report of Five Cases.

Thrombotic microangiopathy (TMA) is an anatomopathological lesion mediated by endothelial dysfunction and characterized by the creation of microthrombi in small vessels. In patients with cancer, it may be due to toxicity secondary to chemotherapy, tumor embolization, or hematopoietic progenitor transplantation. Cancer-associated TMA is an underestimated entity that generally appears in the final stages of the disease, although it may also be the initial manifestation of an underlying cancer. Support treatment is necessary in all cases and, depending on the cause, different targeted therapies may be used. The prognosis is very poor. In this article we present a comprehensive review of the existing literature on the physiological mechanisms of cancer-associated TMA. Afterwards, five clinical cases will be presented of patients who developed TMA and were diagnosed in our Department in 2023. We present a discussion of the different causes that triggered the condition, the possible reasons behind the underestimation of this pathology, and the measures that may be adopted.

Epidemiology of fungal infection in COVID 19 in Spain during 2020 and 2021: a nationwide study.

We realize a nationwide population-based retrospective study to analyze the characteristics and risk factors of fungal co-infections in COVID-19 hospitalized patients as well as describe their causative agents in the Spanish population in 2020 and 2021. Data were obtained from records in the Minimum Basic Data Set of the National Surveillance System for Hospital Data in Spain, provided by the Ministry of Health, and annually published with two years lag. The assessment of the risk associated with the development of healthcare-associated fungal co-infections was assessed using an adjusted logistic regression model. The incidence of fungal co-infection in COVID-19 hospitalized patients was 1.41%. The main risk factors associated were surgery, sepsis, age, male gender, obesity, and COPD. Co-infection was associated with worse outcomes including higher in-hospital and in ICU mortality, and higher length of stay. Candida spp. and Aspergillus spp. were the microorganisms more frequent. This is the first study analyzing fungal coinfection at a national level in hospitalized patients with COVID-19 in Spanish population and one of the few studies available that demonstrate that surgery was an independent risk factor of Aspergillosis coinfection in COVID-19 patients.

Killer-cell immunoglobulin-like receptor polymorphism is associated with COVID-19 outcome: Results of a pilot observational study.

The pathogenesis of COVID-19 warrants unravelling. Genetic polymorphism analysis may help answer the variability in disease outcome. To determine the role of KIR and HLA polymorphisms in susceptibility, progression, and severity of SARS-CoV-2 infection, 458 patients and 667 controls enrolled in this retrospective observational study from April to December 2020. Mild/moderate and severe/death study groups were established. HLA-A, -B, -C, and KIR genotyping were performed using the Lifecodes® HLA-SSO and KIR-SSO kits on the Luminex® 200™ xMAP fluoroanalyser. A probability score using multivariate binary logistic regression analysis was calculated to estimate the likelihood of severe COVID-19. ROC analysis was used to calculate the best cut-off point for predicting a worse clinical outcome with high sensitivity and specificity. A p ≤ 0.05 was considered statistically significant. KIR AA genotype protected positively against severity/death from COVID-19. Furthermore, KIR3DL1, KIR2DL3 and KIR2DS4 genes protected patients from severe forms of COVID-19. KIR Bx genotype, as well as KIR2DL2, KIR2DS2, KIR2DS3 and KIR3DS1 were identified as biomarkers of severe COVID-19. Our logistic regression model, which included clinical and KIR/HLA variables, categorised our cohort of patients as high/low risk for severe COVID-19 disease with high sensitivity and specificity (Se = 94.29%, 95% CI [80.84-99.30]; Sp = 84.55%, 95% CI [79.26-88.94]; OR = 47.58, 95%CI [11.73-193.12], p < 0.0001). These results illustrate an association between KIR/HLA ligand polymorphism and different COVID-19 outcomes and remarks the possibility of use them as a surrogate biomarkers to detect severe patients in possible future infectious outbreaks.

Impact of Prosigna test on adjuvant treatment decision in lymph node-negative early breast cancer-a prospective national multicentre study (EMIT-1).

BACKGROUND: EMIT-1 is a national, observational, single-arm trial designed to assess the value of the Prosigna, Prediction Analysis of Microarray using the 50 gene classifier (PAM50)/Risk of Recurrence (ROR), test as a routine diagnostic tool, examining its impact on adjuvant treatment decisions, clinical outcomes, side-effects and cost-effectiveness. Here we present the impact on treatment decisions. PATIENTS AND METHODS: Patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative pT1-pT2 lymph node-negative early breast cancer (EBC) were included. The Prosigna test and standard histopathology assessments were carried out. Clinicians' treatment decisions were recorded before (pre-Prosigna) and after (post-Prosigna) the Prosigna test results were disclosed. RESULTS: Of 2217 patients included, 2178 had conclusive Prosigna results. The pre-Prosigna treatment decisions were: no systemic treatment (NT) in 27% of patients, endocrine treatment alone (ET) in 38% and chemotherapy (CT) followed by ET (CT + ET) in 35%. Post-Prosigna treatment decisions were 25% NT, 51% ET and 24% CT + ET, respectively. Adjuvant treatment changed in 28% of patients, including 21% change in CT use. Among patients assigned to CT + ET pre-Prosigna, 45% were de-escalated to ET post-Prosigna. Of patients assigned to ET, 12% were escalated to CT + ET and 8% were de-escalated to NT; of those assigned to NT, 18% were escalated to ET/CT + ET. CT was more frequently recommended for patients aged ≤50 years. In the subgroup with pT1c-pT2 G2 and intermediate Ki67 (0.5-1.5× local laboratory median Ki67 score), the pre-Prosigna CT treatment decision varied widely across hospitals (3%-51%). Post-Prosigna, the variability of CT use was markedly reduced (8%-24%). The correlation between Ki67 and ROR score within this subgroup was poor (r = 0.25-0.39). The median ROR score increased by increasing histological grade, but the ROR score ranges were wide (for G1 0-79, G2 0-90, G3 16-94). CONCLUSION: The Prosigna test result changed adjuvant treatment decisions in all EBC clinical risk groups, markedly decreased the CT use for patients categorized as higher clinical risk pre-Prosigna and reduced treatment decision discrepancies between hospitals.

Análisis de los resultados clínicos y las complicaciones.

INTRODUCTION: our aim was to evaluate the clinical outcomes and complications of anterior tibialis tendon transfer (ATTT) in children with dynamic supination after clubfoot treatment. MATERIAL AND METHODS: children with dynamic supination after initial treatment with Ponseti method or surgery who underwent ATTT between 2008 and 2020 were included for evaluation. Demographic data, previous treatment, associated procedures and fixation method were analyzed. Functional results were evaluated with the grading system described by Thompson. Complications and their treatment were analyzed. RESULTS: a total of 39 patients (57 feet) were analyzed. 70% received previous treatment with Ponseti method, 19.3% underwent surgical posteromedial release, and 10.7% another type of surgical treatment. 88% of cases required associated procedures including Achilles tendon lengthening or tenotomy, plantar fasciotomy, tibial osteotomy, lateral column shortening, posterior release. The predominant type of fixation was the pull-out button method (96.5%). The average follow-up was 31.5 months. According to the Thompson grading system, 52 patients presented good results, two fair and three poor. 98.2% of the feet showed active contraction of the transferred tibialis anterior tendon. There were four complications: plantar irritation, synovial cyst in the dorsum of the foot and deep infection. Two feet required unplanned surgery. CONCLUSION: anterior tibialis tendon transfer is an effective technique to correct residual dynamic supination in patients with clubfoot.

Habilidades funcionales de niños, niñas y adolescentes con parálisis cerebral y su relación con el compromiso motor y la discapacidad intelectual en Argentina.

Introduction: Motor compromise characterizes cerebral palsy (CP), and is often associated with intellectual disability (ID). Standardized classification systems have been developed to describe the functions of people with CP. The aim was to functionally characterize children and adolescents aged 0 to 18 years with CP in Argentina and to investigate the association between motor compromise (GMFCS), ID and functional classifications. Methods: Cross-sectional study. Data were collected through family interviews and medical records review. Individuals with CP were included. Data were collected from 19 institutions in different cities of Argentina. Fisher's test and odds ratio [IC95%] were used for data analysis, with significance <0.05. Results: 182 children and adolescents with CP participated. According to GMFCS classification, level V prevailed with 36.3%. Those with more severe motor compromise (GMFCS IV-V) were 72 [25.4;206.0] times and 13 [5.9;28.2] times more likely to present a severe level of MACS and CFCS, respectively. But they were 34 [7.9;146.0] times more likely to have a mild to moderate level of EDACS. Those with DI were 10 [5.1;20.5] times more likely to have severe GMFCS, 6 [3.4;13.2] times more likely to have severe MACS and 4 [2.0;7.8] times more likely to have severe CFCS. On the contrary, they are 4 [1.9;9.5] times more likely to present a mild-moderate EDACS level. Conclusion: the level of GMFCS and the presence of DI influence general functionality and increase severity in engagement, manual and communication skills.

Introducción: El compromiso motor caracteriza la parálisis cerebral (PC), y suele asociarse a la discapacidad intelectual (DI). Se han desarrollado sistemas de clasificación estandarizados para describir las funciones de personas con PC. Objetivo: caracterizar funcionalmente a niños, niñas y adolescentes de 0 a 18 años con PC de Argentina e indagar la asociación entre el compromiso motor (GMFCS), la DI y las clasificaciones funcionales. Métodos: Estudio transversal. Se recolectaron datos a través de entrevistas a las familias y revisión de historias clínicas. Se incluyeron personas con PC. Los datos se recolectaron de 19 instituciones de distintas ciudades de Argentina. Resultados: participaron 182 niños, niñas y adolescentes con PC. Según clasificación GMFCS prevaleció el nivel V con 36,3%. Quienes presentan compromiso motor más severo (GMFCS IV-V), tienen 72 [25,4;206,0] veces y 13 [5,9;28,2] veces más chances de presentar un nivel severo de MACS y CFCS respectivamente. Pero, presentaron 34 [7,9;146,0] veces más chances de un nivel leve a moderado de EDACS. Quienes presentaron DI tuvieron 10 [5,1;20,5] veces más chances de presentar un nivel severo GMFCS, 6 [3,4;13,2] veces más chances un nivel severo MACS y 4 [2,0;7,8] veces más chances de un nivel severo CFCS. Por el contrario, tienen 4 [1,9;9,5] veces más chances de presentar un nivel leve-moderado EDACS. Conclusión: el nivel de GMFCS y la presencia de DI influyen en la funcionalidad general y aumentan la severidad en el compromiso, habilidades manuales y de comunicación.

Resumen: Introducción: la dehiscencia de herida quirúrgica con exposición de material de fijación interna es un grave problema en cirugía ortopédica y un factor importante de infección. Objetivo: descripción del caso inusual de un paciente adulto con dehiscencia de la herida quirúrgica y exposición completa de 20 cm de largo de una placa de cúbito tras seis años de la cirugía, sin signos de infección, consolidación ósea y reepitelización debajo de la placa y adherida al hueso. Caso clínico: hombre de 39 años que sufrió una fractura-luxación de Monteggia, abierta grado II y multifragmentaria. El paciente tenía historia de drogodependencia en tratamiento con metadona. Fue tratado con fijación interna del cúbito mediante una placa de reconstrucción larga. Postoperatoriamente, el paciente dejó de acudir para evaluación. A los seis años de la cirugía presentaba una completa exposición de la placa (20 cm de longitud), sin signos de infección y consolidación con malalineación de la fractura. Tras el retiro de la placa se observó epitelización espontánea adherida al lecho óseo cubital. La cobertura cutánea fue completa a los dos meses. Conclusión: aunque inusual, es posible la consolidación ósea y la ausencia de infección en una fractura abierta con exposición de larga evolución de una placa de antebrazo en el adulto.

Abstract: Introduction: surgical wound dehiscence with exposure of internal fixation material is a serious problem in orthopedic surgery and an important factor for infection. Objective: presentation of an unusual case of an adult patient with surgical wound dehiscence and complete exposure of 20 cm of the ulnar plate after six years of surgery, without infection signs, with bone healing and skin behind the plate. Case presentation: 39-year-old man with an open Gustilo II Monteggia fracture-dislocation multifracture. The patient had a history of drug dependence. He had an open reduction and internal fixation with an ulnar reconstruction plate. The patient did not have any follow-up. After six years of the surgery, there was a complete exposure of the plate (20 cm) without infection and healing of the fracture with misalignment. After removing the plate, we observed spontaneous epithelialization attached to the bone bed. Skin coverage was complete at two months. Conclusion: although unusual, bone consolidation without infection is possible in an open fracture with long-standing exposure to a forearm plate in the adult.

Tiroidectomía transoral endoscópica por abordaje vestibular (TOETVA): primer caso en Perú / Transoral endoscopic thyroidectomy via vestibular approach (TOETVA): first case in Peru

RESUMEN La calidad de vida luego de la cirugía de la glándula tiroides es tan importante como el control de la enfermedad. Para mejorar los resultados cosméticos y la satisfacción del paciente se usan abordajes endoscópicos usando incisiones fuera de la región cervical. La tiroidectomía transoral endoscópica no deja ninguna cicatriz visible en la piel y es una técnica quirúrgica segura. Se presenta el caso de una paciente mujer de 29 años con una tumoración benigna de la glándula tiroides con síntomas compresivos y preocupaciones estéticas, sometida a hemitiroidectomia derecha mediante abordaje transoral vestibular endoscópico en un tiempo de 150 minutos y sangrado mínimo. Los resultados son comparables con la técnica quirúrgica abierta, con un mejor resultado estético y mejora en la calidad de vida.

ABSTRACT Quality of life after thyroid gland surgery is as important as disease control. To improve cosmetic results and patient satisfaction, endoscopic approaches are used using incisions outside the cervical region. Endoscopic transoral thyroidectomy does not leave any visible scarring on the skin. We present the case of a 29-year-old female patient with a benign thyroid gland tumor with compressive symptoms and aesthetic concerns, who underwent a right hemithyroidectomy by means of an endoscopic transoral vestibular approach in a time of 150 minutes and minimal bleeding, without complications in the postoperative period. The transoral endoscopic vestibular approach for endoscopic resection of the thyroid gland is safe and the results are comparable with the open surgical technique, with a better cosmetic result and improved quality of life.
