Perceived surgical difficulty of mandibular third molar extraction. A comparative cross-sectional study of dentists with postgraduate qualification in oral surgery and maxillofacial surgeons in a Spanish subpopulation.

BACKGROUND: Mandibular third molar (MTM) extraction is one of the most frequently performed surgeries in the oral cavity. Establishing the level of surgical difficulty pre-operatively is an essential step to ensure correct treatment planning. In Spain, MTM extraction - especially in cases presenting greater difficulty - is normally performed by doctors specializing in oral and maxillofacial surgery, or by dentists with postgraduate qualifications in oral surgery. The present work set out to analyze the extent to which perceptions of surgical difficulty of the said intervention vary in relation to professional training. MATERIAL AND METHODS: This cross-sectional, descriptive, observational study took the form of a survey. Using a visual analog scale (VAS), participants evaluated both the perceived difficulty of 30 cases of MTM extraction described by means of digital panoramic radiographs and the perceived difficulty deriving from a series of factors conditioning MTM extraction. The results underwent statistical analysis with SPSS Statistics 28.0 software. Non-parametric tests (Mann Whitney test for independent samples and the Kruskal-Wallis test) were applied. RESULTS: A total of 213 surveys were available for analysis. Both groups awarded the greatest importance to clinical experience, followed by anatomical and radiographic factors, root morphology obtaining the highest score among anatomical factors (9.01±1.42), while proximity of the MTM to the inferior alveolar nerve was regarded as the least important anatomical factor (8.11±2.54). Significant differences were only found for patient age, whereby maxillofacial surgeons awarded this factor more importance than dentists. CONCLUSIONS: The different training received by dentists specialized in oral surgery and maxillofacial surgeons did not influence either perceptions of surgical difficulty of MTM extraction, or opinions as to the factors influencing surgical difficulty.

Xanthogranulomatous endometritis.

Xanthogranulomatous endometritis (XGE) is an uncommon inflammatory benign condition that can mimic endometrial cancer. The majority of the reported cases of XGE have been observed in postmenopausal women, often presenting clinically as haematometra or benign senile pyometra. We report a case of XGE in a 73-year-old woman who presented with pyometra. Diagnostic hysteroscopy is an important tool when accompanied by endometrial samples for histology in suspected cases. Knowledge of this uncommon disease is crucial for accurate diagnosis. XGE is a benign condition, however, there have been reported cases of chronic active XGE and bacterial infection in which hysterectomy was required due to complications.

External urology consultation quality at a third-level public hospital in Mexico.

INTRODUCTION: Patient satisfaction is the degree of conformity with the healthcare they receive. It is real evidence and one of the most important factors in determining the effectiveness and quality of healthcare systems. OBJECTIVE: To identify the quality of care in the Urology outpatient department of a third-level hospital. MATERIALS AND METHODS: The NHS (National Health Service) 2018 quality of care questionnaire with 11 sections, 133 items, and duration of approximately 25min was randomly administered to 250 patients attending Urology outpatients at a third-level public hospital in Mexico. RESULTS: According to responses, 92% (n=230) knew the reason for the consultation. 64.8% (n=162) had a consultation with the same physician by whom they were initially seen. The longest reported hospital wait time before being seen was more than 2h in 29.6% (n=74). As for consultation time, 212 patients responded and the duration was 11-20min in 52.8% (n=112). Finally, 33.2% (n=83) considered the quality of service to be good. CONCLUSIONS: The use of the NHS 2018 survey in the Urology service at a third-level public hospital in Mexico is feasible, since we managed to obtain a significant and continuous improvement in all its indicators which is satisfactory for all.

The Mexican consensus on fecal incontinence.

Fecal incontinence is the involuntary passage or the incapacity to control the release of fecal matter through the anus. It is a condition that significantly impairs quality of life in those that suffer from it, given that it affects body image, self-esteem, and interferes with everyday activities, in turn, favoring social isolation. There are no guidelines or consensus in Mexico on the topic, and so the Asociación Mexicana de Gastroenterología brought together a multidisciplinary group (gastroenterologists, neurogastroenterologists, and surgeons) to carry out the «Mexican consensus on fecal incontinence¼ and establish useful recommendations for the medical community. The present document presents the formulated recommendations in 35 statements. Fecal incontinence is known to be a frequent entity whose incidence increases as individuals age, but one that is under-recognized. The pathophysiology of incontinence is complex and multifactorial, and in most cases, there is more than one associated risk factor. Even though there is no diagnostic gold standard, the combination of tests that evaluate structure (endoanal ultrasound) and function (anorectal manometry) should be recommended in all cases. Treatment should also be multidisciplinary and general measures and drugs (lidamidine, loperamide) are recommended, as well as non-pharmacologic interventions, such as biofeedback therapy, in selected cases. Likewise, surgical treatment should be offered to selected patients and performed by experts.

Resistencia genotípica del HIV a los antirretrovirales en niños de Argentina entre 2006 y 2021 / HIV genotypic drug resistance to antiretrovirals in children in Argentina between 2006 and 2021

Introducción: La resistencia del HIV a los antirretrovirales (ARVs) es una de las principales causas de fallo terapéutico en niños, niñas y adolescentes que conviven con el virus. Desde el año 2006, el Laboratorio de Biología Celular y Retrovirus del Hospital Garrahan realiza el estudio genotípico de resistencia (ER) del HIV-1 a los ARVs a fin de identificar mutaciones que disminuyen la susceptibilidad del virus a los fármacos que componen el tratamiento ARV. Objetivos: El objetivo del trabajo fue estudiar el tipo y frecuencia de resistencia del HIV a los ARVs, a través de un análisis de 371 ER realizados entre los años 2006 y 2021 en niños, niñas y adolescentes con HIV-1 adquirido por transmisión vertical y con solicitud médica de ER por presentar fallo terapéutico. Resultados: Entre los años 2006 y 2013 la proporción de casos con resistencia a al menos una clase de fármaco ARV fue mayor al 90%, sugiriendo una asociación directa entre el fallo virológico y la disminución en la susceptibilidad del HIV-1 a uno o más componentes del TARV. A partir del año 2012, se observa una disminución progresiva del nivel de resistencia de HIV-1, llegando al 50% en 2021 (p<0.0001). La frecuencia de mutaciones de resistencia fue diferente para cada una de las clases de ARVs. Mientras que la resistencia a INNTR no sufrió cambios significativos a lo largo del período de estudio, oscilando entre 27% y 75%. La proporción de mutaciones a IPs en pacientes con fallo virológico disminuyó de 87% en 2006 a 17% en 2021 y para los INTR, disminuyó de 79% en 2006 a 45% en 2021. Conclusión: El nivel de resistencia a los ARVs ha disminuido de manera sustancial a lo largo de los últimos 16 años, probablemente por el uso de nuevos fármacos ARV con alta potencia que posibilitaron la intensificación de los tratamientos ARV y la implementación de criterios de fallo terapéutico más estrictos tanto a nivel clínico como virológico (AU)

Introduction: HIV resistance to antiretroviral (ARV) drugs is one of the main causes of therapeutic failure in children and adolescents living with the virus. Since 2006, the Cell Biology and Retrovirus Laboratory of the Garrahan Hospital has been performing the genotypic study of HIV-1 resistance to ARV drugs in order to identify mutations that reduce the susceptibility of the virus to the drugs that constitute ARV treatment. Objectives: The aim of this study was to assess the type and frequency of HIV resistance to ARV drugs through an analysis of 371 genotype studies performed between 2006 and 2021 in children and adolescents with HIV-1 acquired through motherto-child transmission and with medical request for genotype study due to therapeutic failure. Results: Between 2006 and 2013, the proportion of cases with resistance to at least one ARV drug class was greater than 90%, suggesting a direct association between virologic failure and decreased susceptibility of HIV-1 to one or more components of ART. From 2012 onwards, a progressive decrease in the level of HIV-1 resistance was observed, reaching 50% in 2021 (p<0.0001). The frequency of resistant mutations was different for each of the ARV classes, while resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) did not change significantly over the study period, ranging from 27% to 75%. The proportion of drug-resistant mutations to protease inhibitors (PI) in patients with virologic failure decreased from 87% in 2006 to 17% in 2021 and for NNRTIs from 79% in 2006 to 45% in 2021. Conclusion: The level of resistance to ARV drugs has decreased substantially over the last 16 years, probably due to the use of new ARV drugs with high potency that allowed the intensification of ARV treatments and the implementation of stricter criteria for therapeutic failure both clinically and virologically (AU)

Técnica del acceso apical con injerto simultáneo de tejido conectivo subepitelial para el tratamiento de una fenestración del tejido blando peri-implantario: descripción de la técnica y presentación de un caso clínico / Apical access technique with simultaneous grafting of subepithelial connective tissue for the treatment of peri-implant soft tissue fenestration: description of the technique and presentation of a clinical case

Cuando hablamos de defectos sobre implantes y tejidos blandos lo asociamos principalmente a dehiscencias del tejido blando. Generalmente estamos cada vez más acostumbrados a tratar este tipo de patologías. Sin embargo, en la practica clínica diaria encontramos otras preocupaciones estéticas sobre el tejido blando que requieren estudio y tratamiento. Desde este punto de vista, este informe de caso clínico tuvo como objetivo describir un abordaje quirúrgico mediante la técnica del acceso apical para el tratamiento de una fenestración estética sobre los tejidos blandos periimplantarios. La selección de la técnica bilaminar mediante un acceso apical con injerto de tejido conectivo simultaneo, parece ofrecer resultados prometedores para el tratamiento de deformidades del tejido blando periimplantario. (AU)

When we talk about implant and soft tissue defects we mainly associate them with soft tissue dehiscence. Generally, we are more and more accustomed to treating this type of pathology. However, in daily clinical practice we find other aesthetic concerns about soft tissue that require study and treatment. From this point of view, the aim of this clinical case report was to describe a surgical approach using the apical access technique for the treatment of an aesthetic fenestration on the peri-implant soft tissues. The selection of the bilaminar technique using an apical access with simultaneous connective tissue grafting seems to offer promising results for the treatment of peri-implant soft tissue deformities.

El tipo 1 es la más frecuente (34,7%), sin casos del Tipo 4. No se identificó diferencia entre los distintos tipos de irrigación con relación a las variables demográficas y comorbilidades. Discusión: Al comparar nuestra serie con la oriental se evidenció similar frecuencia en tipos 1 y 6, mayor en tipos 3 y 5, y tipos 2 y 4 con menor representación. Se identificó un mayor aporte en la irrigación del AEC por la arteria cólica izquierda (ACI) en la población estudiada (64,6%). Conclusión: Nuestra población tiene mayor participación de ACI en irrigación del AEC que orientales (64,6% vs 49,6%), los tipos más frecuentes son 1, 3 y 6, el Tipo 1 es la forma más frecuente de irrigación, similar a Fukuoka (34,7% vs 39,7%), Tipo 3 tiene mayor representación en nuestra población que en la oriental (29,9% vs 9,9%).

Objective: To identify the vascular distribution patterns of the splenic flexure of the colon (AEC) in the Chilean population for comparison with the oriental literature (Fukuoka). Methods: Descriptive, cross-sectional study. The irrigation of the AEC of images with the Urotac protocol performed at the INDISA Clinic between 2020 and 2021 (n = 127) was characterized, classifying them into 6 types described by Fukuoka. Demographic characteristics and comorbidities were evaluated. Variables were analyzed using descriptive statistics and significance using the Chi2 test. Results: There are differences in the types of irrigation of the AEC between the local series and Fukuoka, irrigation type 3 was the one that presented the greatest variation (p < 0.05). Type 1 is the most frequent (34.7%), with no cases of Type 4. No difference was identified between the different types of irrigation in relation to demographic variables and comorbidities. Discussion: When comparing our series with the eastern one, a similar frequency was found in types 1 and 6, higher in types 3 and 5, and types 2 and 4 with less representation. A greater contribution was identified in the irrigation of the AEC by the left colic artery (ICA) in the population studied (64.6%). Conclusion: Our population has a greater participation of ICA in AEC irrigation than Orientals (64.6% vs 49.6%), the most frequent types are 1, 3 and 6, Type 1 is the most frequent form of irrigation, similar to Fukuoka (34.7% vs 39.7%), Type 3 is more represented in our population than in the eastern one (29.9% vs 9.9%).

The impact of frailty on intra-hospital survival in older patients with COVID-19 infection: the importance of early identification. SEMI-COVID National Registry.

BACKGROUND: Emerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival. METHODS: This observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival. RESULTS: A total of 1,878 participants (52% men and 48% women) were included, with 1,351 (71.9%) survivors and 527 (28.1%) non-survivors. The non-survivor group had higher mean age (83.5 vs. 81 years), comorbidities (6.3 vs. 5.3 points on the Charlson index), degree of dependency (26.8% vs. 12.4% severely dependent patients), and frailty (34.5% vs. 14.7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate-severe degree of frailty is the primary factor independently associated with shorter survival [HR 2.344 (1.437-3.823; p<0.001) for CFS 5-6 and 3.694 (2.155-6.330; p<0.001) for CFS 7-9]. CONCLUSION: Frailty is the main predictor of adverse outcomes in older patients with COVID-19. The utilization of tools such as the Clinical Frailty Scale is crucial for early detection in this population.

Intensity of focused waves near turning points.

A wave near an isolated turning point is typically assumed to have an Airy function profile with respect to the separation distance. This description is incomplete, however, and is insufficient to describe the behavior of more realistic wave fields that are not simple plane waves. Asymptotic matching to a prescribed incoming wave field generically introduces a phase front curvature term that changes the characteristic wave behavior from the Airy function to that of the hyperbolic umbilic function. This function, which is one of the seven classic "elementary" functions from catastrophe theory along with the Airy function, can be understood intuitively as the solution for a linearly focused Gaussian beam propagating in a linearly varying density profile, as we show. The morphology of the caustic lines that govern the intensity maxima of the diffraction pattern as one alters the density length scale of the plasma, the focal length of the incident beam, and also the injection angle of the incident beam are presented in detail. This morphology includes a Goos-Hänchen shift and focal shift at oblique incidence that do not appear in a reduced ray-based description of the caustic. The enhancement of the intensity swelling factor for a focused wave compared to the typical Airy solution is highlighted, and the impact of a finite lens aperture is discussed. Collisional damping and finite beam waist are included in the model and appear as complex components to the arguments of the hyperbolic umbilic function. The observations presented here on the behavior of waves near turning points should aid the development of improved reduced wave models to be used, for example, in designing modern nuclear fusion experiments.

Effectiveness of a digital application to improve stroke knowledge for kids.

INTRODUCTION: Stroke is highly prevalent in Latin America and one of the leading causes of morbidity and mortality in the world. Educating children about stroke has been established as an effective method to detect symptoms early, reduce hospital visits, and raise awareness among adults. OBJECTIVE: To analyze the effectiveness of a mobile application to improve knowledge and understanding of stroke among children. METHOD: We conducted a focus group session including 12 children in order to analyze the behavior of 6 questions previously validated by expert neurologists. Subsequently, 105 primary school students between the ages of 7 and 12 completed a questionnaire on stroke symptoms and how to contact the emergency services before and after using an application on stroke symptoms. Qualitative analyses and the Student t test were used to verify the existence of differences between pre- and post-intervention test results. RESULTS: After a single 40-min working session with the application, between 50% and 67% of the children were able to identify the signs of stroke, and 96.2% knew the national emergency services telephone number. Statistical analysis revealed statistically significant differences before and after the intervention with the digital application (t=19.54; p<0.001) and intragroup differences in the post-intervention test results (t=40.71; p<0.001). CONCLUSION: Primary school children who used our digital application increased their knowledge, understanding, and learning of stroke symptoms.

[Prevalence of neurodevelopmental disorders in children from the rural population of Oaxaca evaluated by means of the Child Development Evaluation test]. / Prevalencia de alteraciones en el neurodesarrollo en niños de población rural de Oaxaca evaluados mediante la prueba Evaluación de Desarrollo Infantil.

INTRODUCTION: During child's growth, access to health, nutrition, opportunities for stimulation, and early learning are necessary for an optimal development of the central nervous system. In rural areas there is a lack of access to them, and this has an impact on children's neurodevelopment. OBJECTIVE: To identify the prevalence of lag or delay in the development of children in rural areas. SUBJECTS AND METHODS: A descriptive, cross-sectional and prospective study, with non-probabilistic convenience sampling, where 97 infants from 1 month of age to one day before their 5th birthday, all belonging to rural communities in the state of Oaxaca, Mexico, were applied the Child Development Evaluation, designed and validated for the Mexican population in the early detection of neurodevelopmental problems. RESULTS: The prevalence of developmental disorders was 43%, with predominance in the male sex. The area of development with the greatest affectation was language, with a total of 29%, and in second place gross motor skills, with 18%; however, neurological affectation as the only one occurred in 2% of the participants, the most prevalent risk factors were the urinary tract infections in 56% of mothers. CONCLUSION: There is a percentage greater than 30% of neurodevelopmental disorders in rural communities due to social risk factors that infants face, such as the difficult access to medical care, a poorly stimulating environment and bad nutrition.

CT scan for early diagnosis of anastomotic leak after colorectal surgery: is rectal contrast useful?

BACKGROUND: Computed tomography (CT) scan with rectal contrast enema (RCE-CT) could increase the detection rate of anastomotic leaks (AL) in the early postoperative period following colorectal surgery, compared to CT scan without RCE. The aim of this study was to assess the benefit of RCE-CT for the early diagnosis of AL following colorectal surgery. METHODS: Patients who had a RCE-CT for suspected AL in the early postoperative period following colorectal surgery with anastomosis between January 2012 and July 2019 at the Dijon University Hospital were retrospectively included. All images were reviewed by two independent observers who were blinded to the original report. The reviewers reported for each patient whether an AL was present or not in each imaging modality (CT scan, then RCE-CT). Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were then calculated to determine the diagnostic performance of each modality. RESULTS: One hundred and thirty-nine patients were included. RCE-CT had an increased NPV compared to CT scan (82% vs 77% (p = 0.02) and 84% vs 68% (p < 0.0001) for observers 1 and 2, respectively). RCE-CT had an increased sensitivity compared to CT scan (79% vs 48% (p < 0.0001) for observer 2). RCE-CT had a significant lower false-negative rate for both observers: 18% vs 23% (p = 0.02) and 16% vs 32% (p < 0.0001). CONCLUSIONS: RCE-CT improved the detection rates of AL in the early period following colorectal surgery. RCE-CT should be recommended when a CT scan is negative and AL is still suspected.

La intervención más utilizada para la resolución de la EPS aguda es el drenaje bajo anestesia formal con curetaje y/o marsupialización (51,1%). El 45,3% de los cirujanos/as cambia de técnica durante su carrera. Discusión: Gracias a la amplia distribución y representatividad de los encuestados se logró plasmar la preferencia de manera realista acerca de las inclinaciones en el manejo de la EPS por parte de los subespecialistas del continente, aportando información de la que no se tiene precedente. Conclusión: Las técnicas abiertas son las preferidas para la resolución de la EPS crónica, las técnicas más utilizadas son marsupialización, destechamiento y Karydakis. Es frecuente el cambio de técnica quirúrgica preferente dentro de los subespecialistas, existiendo una relación entre escoger técnicas abiertas en la medida que los cirujanos/as tienen más años de experiencia.

Aim: To characterize the preferences and frequency of surgical techniques for the resolution of pilonidal disease (PSD) in colorectal surgeons of Latin America. Materials and Method: Cross-sectional descriptive and analytical study using an electronic survey validated by expert peers. Distributed among colorectal surgeons in Latin America. Surgeons who were not subspecialists in colorectal surgery were excluded. Results: 372 responses were obtained from subspecialist surgeons in colorectal surgery from 15 Latin American countries, with a mean of 18.9 ± 12.5 years as subspecialists. 66.7% use open techniques for chronic PSD, the most used techniques: marsupialization (31.5%), unroofing (27.7%) and resection with the Karydakis technique (17.7%), Limberg flap (6, 1%), Bascom (5.4%), Z or VY plasties (4%), McFee (3.8%) and Epsit (3.8%). The most used intervention for the resolution of acute PSD is drainage under formal anesthesia with curettage and/or marsupialization (51.1%). 45.3% of surgeons change techniques during their career. Discussion: Due to the wide distribution and representativeness of the respondents, it was possible to capture the preference in a realistic way about the management of the PSD by the subspecialists of the continent, contributing with information with which there is no precedent. Conclusion: Open techniques are preferred for the resolution of chronic PSD, marsupialization, unroofing and Karydakis were used the most. The change of surgical technique within subspecialists is frequent, there is a relationship between preferring open techniques to the extent that surgeons have more years of experience.
