Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Enfermedad de Lhermitte-Duclos y síndrome de Cowden. Reporte de un caso / Lhermitte-Duclos Disease and Cowden Syndrome. A Case Report

Presentación del caso. Se trata de una paciente femenina de 45 años con antecedentes de hipertensión arterial y múltiples cirugías por cáncer, entre ellas, cáncer de tiroides, carcinoma de parótida, cáncer de mama y cáncer endometrial. De manera incidental se identificó una lesión en el hemisferio cerebeloso derecho en una tomografía de senos paranasales, que fue confirmada a través de una resonancia magnética cerebral. La lesión presentaba una apariencia estriada, característica de gangliocitoma displásico del cerebelo o enfermedad de Lhermitte-Duclos. Considerando los antecedentes de diversos tipos de cáncer y los criterios de diagnóstico propuestos por el Consorcio Internacional Cowden y la Red Nacional Integral del Cáncer, se estableció el diagnóstico de síndrome de Cowden que había pasado desapercibido hasta el momento. Intervención terapéutica. Posteriormente, la paciente fue hospitalizada debido al crecimiento de una masa metastásica en el hemicuello derecho con afectación del plexo braquial, adenopatías cervicales, infraclaviculares y axilares derechas. Evolución clínica. En la actualidad, se encuentra recibiendo tratamiento paliativo con el objetivo de controlar los síntomas y mejorar su calidad de vida, ya que expresó su negativa a someterse a una intervención quirúrgica de resección tumoral

Case presentation. The report is of a 45-year-old female patient with a history of high blood pressure and multiple surgeries for cancer, including thyroid cancer, parotid carcinoma, breast cancer, and endometrial cancer. Incidentally, a lesion in the right cerebellar hemisphere was identified in a tomography of the paranasal sinuses, which was later confirmed in a brain magnetic resonance. The lesion had a striated appearance, characteristic of dysplastic gangliocytoma of the cerebellum or Lhermitte-Duclos disease. Considering the history of various types of cancer and the diagnostic criteria proposed by the International Cowden Consortium and the National Comprehensive Cancer Network, the diagnosis of Cowden syndrome, which had gone unnoticed until now, was established. Treatment. Subsequently, the patient was hospitalized due to the growth of a metastatic mass in the right hemicollar with involvement of the brachial plexus, cervical, infraclavicular, and right axillary lymph nodes. Outcome. She is receiving palliative treatment to control the symptoms and improve her quality of life, since she expressed her refusal to undergo tumor resection surgery

Fibroelastoma, uma Doença Incidentaloma? - Imagem de Casos de Fibroelastomas como Achados Incidentais em Quatro Pacientes, Quatro Valvas Diferentes / Fibroelastoma, an Incidentaloma Disease? - Image Cases of Fibroelastomas as Incidental Findings in Four Patients, Four Different Valves

Resumo Os fibroelastomas são o segundo tumor cardíaco benigno mais comum. São estruturas pequenas, avasculares, com uma dimensão média de 9mm, podendo atingir até 70mm, habitualmente aderentes à superfície das válvulas cardíacas (válvulas aórtica e mitral são as mais comumente afetadas, seguidas das válvulas tricúspide e pulmonar). A etiologia não é clara, sendo a hipótese de formação de microtrombos nas margens de coaptação das válvulas a mais aceite. Na ecocardiografia apresentam aspeto pediculado, móvel, com superfície filamentosa, tipicamente com uma aparência pontilhada nas margens e ecolucente. Do ponto de vista clínico, podem estar associados a fenómenos embólicos, no entanto, na maioria dos casos o diagnóstico é incidental. Apresentamos de seguida quatro casos de diagnóstico incidental de fibroelastomas nas quatro válvulas cardíacas, diagnosticados por ecocardiograma transtorácico (ETT) (Vídeo 1; Figura 1). Vídeo 1 Da esquerda para a direita, de cima para baixo: fibroelastomas no folheto anterior da válvula tricúspide, folheto anterior da válvula mitral, cúspide esquerda da válvula pulmonar e cúspide esquerda da válvula aórtica, cada um correspondendo a um doente diferente. Em: http://abccardiol.org/supplementary-material/2024/12102/2023-0222_IM_video01.mp4 Figura 1 Da esquerda para a direita, de cima para baixo: fibroelastomas no folheto anterior da válvula tricúspide, folheto anterior da válvula mitral, cúspide esquerda da válvula pulmonar e cúspide esquerda da válvula aórtica, cada um correspondendo a um doente diferente.

Abstract Fibroelastomas are the second most common benign cardiac tumor1. They are small avascular structures with a mean size of 9mm, ranging up to 70mm, usually attached to the heart valves' surface (aortic and mitral are the most affected, followed by tricuspid and pulmonary valves). Their etiology is unclear, but the hypothesis of coalescence of microthrombus at the coaptation margins of valves is the most widely accepted theory. On echocardiography, they are pedicled, mobile, with a filamentous surface, and usually have a speckled appearance with echolucencies and a stippled pattern near the edges. Clinically, they may be associated with embolic phenomena; however, in most cases, the diagnosis is incidental. We present a series of four clinical cases with an incidental diagnosis of fibroelastomas across the four cardiac valves as assessed by transthoracic echocardiography (Video 1; Figure 1). Video 1 From left to right and top to bottom: fibroelastomas of the anterior leaflet of the tricuspid valve, anterior leaflet of the mitral valve, left cusp of the pulmonary valve and left cuspid of the aortic valve, each corresponding to a different patient.

Littoral cell angioma of the spleen: case report and literature review

ABSTRACT Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention.

Hallazgos incidentales en medicina genómica / Incidental Findings in Genomic Medicine

Las técnicas de Biología Molecular de última generación, como es la secuenciación masiva en paralelo o NGS (Next Generation Sequencing), permite obtener gran cantidad de información genómica, la cual muchas veces va más allá de la detección de una variante patogénica en un gen que explique la patología (hallazgo primario). Es así como surgió desde hace años la discusión internacional respecto a la decisión a tomar frente a los hallazgos secundarios accionables, es decir, aquellos hallazgos de variantes clasificadas como patogénicas o probablemente patogénicas que no están relacionadas con el fenotipo del paciente, pero que tiene alguna medida preventiva o tratamiento posible y, por lo tanto, podría ser de utilidad para la salud del paciente. Luego de revisar la bibliografía internacional y debatir entre los expertos del Hospital de Pediatría Garrahan, se logró establecer una política institucional y reforzar el hecho de que se trata de una disciplina multidisciplinaria. Así, fue posible definir que solo se atenderá las cuestiones relacionadas con la edad pediátrica, dejando para un tratamiento posterior aquellas variantes detectadas en genes que sean accionables en edad adulta. En el Hospital Garrahan, ha sido posible definir claramente cómo proceder frente a los hallazgos secundarios, al adaptar el consentimiento informado a esta necesidad, definiendo cuándo serán informados, y sabiendo que serán buscados intencionalmente en los genes clínicamente accionables enlistados en la última publicación del American College of Medical Genetics and Genomics, siempre y cuando el paciente/padre/tutor lo consienta (AU)

The latest generation of molecular biology techniques, including massive parallel sequencing or NGS (Next Generation Sequencing), allows us to obtain a whealth of genomic information, which often goes beyond the detection of a pathogenic variant in a gene that explains the pathology (primary finding). As a result, an international discussion has arisen over the years regarding the decision-making concerning actionable secondary findings, it means, those findings of variants classified as pathogenic or probably pathogenic that are not related to the patient's phenotype, but which have some possible preventive measure or treatment and, therefore, could be useful for the patient's health. After reviewing the international literature and discussing among the experts of the Hospital de Pediatría Garrahan, an institutional policy was established and the concept that this is a multidisciplinary discipline was reinforced. Consequently, it has been defined that only issues related to children will be addressed, reserving those variants detected in genes that are actionable in adulthood for later treatment. At Garrahan Hospital, we were able to clearly define how to proceed with secondary findings by adapting the informed consent to this need, defining when they will be reported, and knowing that they will be intentionally searched for in the clinically actionable genes listed in the latest publication of the American College of Medical Genetics and Genomics, as long as the patient/parent/guardian consents (AU)

Métodos diagnósticos cardiovasculares en pacientes con diabetes mellitus. Revisión / Cardiovascular diagnostic methods in patients with diabetes mellitus. A review

Resumen Las enfermedades cardiovasculares constituyen la causa más común de mortalidad en el mundo. Actualmente, la diabetes mellitus tipo 2 (DM2) representa uno de los principales factores de riesgo de eventos adversos cardiovasculares mayores. Los pacientes que las padecen tienen un riesgo cuatro veces mayor de desarrollar insuficiencia cardíaca y una mortalidad de 10 a 12 veces mayor. La ecocardiografía en todas sus modalidades es la mejor herramienta clínica para el diagnóstico de la insuficiencia cardíaca, ya que proporciona imágenes estáticas y dinámicas del corazón que permiten identificar cambios estructurales y funcionales, como alteraciones en las presiones, cambios de flujo, fracción de expulsión del ventrículo izquierdo y remodelación anatómica de las superficies miocárdicas.

Abstract Cardiovascular diseases are the most common cause of mortality in the world. Currently, type 2 diabetes mellitus (T2DM) is one of the main risk factors for major adverse cardiovascular events. T2DM patients have a four-fold higher risk of developing heart failure and 10 to 12 times higher mortality. Echocardiography in all its modalities is the best clinical tool for heart failure diagnosis, since it provides static and dynamic images of the heart that allow to identify structural and functional changes, such as pressure variations, flow changes, left ventricular ejection fraction and myocardial surfaces anatomical remodeling.

Acute abducens nerve palsy with acute disseminated encephalomyelitis-like presentation following COVID-19 vaccination

We report two adult cases of abducens nerve palsy presenting immediately (within weeks) after they received the first dose of Covishield vaccination. Magnetic resonance imaging (MRI) of the brain obtained after the onset of diplopia demonstrated demyelinating changes. The patients had associated systemic symptoms. Post-vaccination demyelination typically known as acute disseminated encephalomyelitis (ADEM) associated with several vaccines is more common in children. Although the mechanism of the nerve palsy remains unclear, it is suspected to be related to the post-vaccine neuroinflammatory syndrome. Cranial nerve palsies and ADEM-like presentations may represent part of the neurologic spectrum following COVID-vaccination in adults, and ophthalmologists should be aware of these sequelae. Although cases of sixth nerve palsy following COVID vaccination are already reported, associated MRI changes have not been reported from India.

Achados tomográficos incidentais de calcificações coronarianas: um estudo de prevalência na região sul do Brasil / Incidental tomographic findings of coronary artery calcifications: a prevalence study in southern Brazil

Fundamento: As calcificações de artérias coronárias (CAC) mostram-se como fator preditivo de doenças cardiovasculares (DCV). A tomografia computadorizada (TC) de tórax com protocolo de aquisição de baixa dose apresenta acurácia na identificação de CAC e propicia achados incidentais dessas calcificações, que são comumente negligenciados. Este estudo analisará a prevalência de achados incidentais de calcificação em artérias coronárias em indivíduos não cardiopatas submetidos à TC de tórax. Métodos: Estudo transversal consecutivo de caráter analítico e descritivo. Foram incluídos indivíduos de ambos os sexos que realizaram TC de tórax por encaminhamento, acima de 18 anos e não cardiopatas. A coleta de dados foi realizada por meio de prontuários e ficha de anamnese auto aplicada. As variáveis referentes às CAC e à extensão do comprometimento foram obtidas a partir da reavaliação das imagens de TC de tórax disponíveis no sistema da instituição. Os exames foram anonimizados e avaliados por dois médicos radiologistas experientes. Considerou-se como estatisticamente significativo p≤0,05. Resultados: Foram analisados 397 exames. Encontrou-se prevalência de calcificações em 176 (44%) dos casos. A existência dessas calcificações coronárias está relacionada à idade (p<0,001). As calcificações possuem relação com o sexo (p = 0,03) com maior razão de chance de desenvolvimento em homens (odds ratio [OR] = 1,55). O tabagismo (p<0,001), o sedentarismo (p<0,001), a hipertensão arterial sistêmica (p<0,001), o diabetes mellitus (p = 0,04) e as dislipidemias (p<0,001) mostraram associação positiva. Conclusão: A prevalência de achados incidentais de CAC foi de 44%; variam em maior número entre leve e grave; maior razão de chance no sexo masculino e aumento da prevalência com a idade. Portanto, a TC de tórax mostra-se um efetivo método para avaliar as CAC, e juntamente com a história clínica do paciente pode ser utilizada para medir os fatores de risco para doenças cardiovasculares e intervir no desfecho do quadro.(AU)

Introduction: Coronary artery calcifications (CAC) are shown to be a predictive factor of cardiovascular diseases. Computed tomography (CT) of the chest with a low-dose acquisition protocol is accurate in identifying CAC and provides incidental findings of these calcifications, which are commonly overlooked. This study will analyze the prevalence of incidental findings of calcification in coronary arteries in non-cardiac individuals undergoing chest CT. Methods: Consecutive cross-sectional study of an analytical and descriptive nature. Individuals of both genders who underwent chest CT by referral, over 18 years of age and without heart disease were included. Data collection was carried out using medical records and a self-applied anamnesis form. The variables referring to the CAC and the extension of the impairment were obtained from the reassessment of the chest CT images available in the institution's system. The exams were anonymized and evaluated by two experienced radiologists. P≤0.05 was considered statistically significant. Results: 397 exams were analyzed. A prevalence of calcifications was found in 176 (44%) of the cases. The existence of these coronary calcifications is related to age (p<0.001). Calcifications are related to gender (p = 0.03) with a higher odds ratio of development in men (odds ratio [OR] = 1.55). Smoking (p<0.001), sedentary lifestyle (p<0.001), systemic arterial hypertension (p<0.001), Diabetes Mellitus (p = 0.04), and dyslipidemia (p<0.001) showed a positive association. Conclusion: The prevalence of incidental CAC findings was 44%; vary in greater numbers between mild and severe; higher odds ratio in males and increased prevalence with age. Therefore, chest CT proves to be an effective method to assess CAC, and together with the patient's clinical history, it can be used to measure risk factors for CVD and intervene in the outcome of the condition.(AU)

Incidental tomographic findings in patients with a Confirmed Diagnosis of COVID-19: An Observational Study / Achados Tomográficos Incidentais em Pacientes com Diagnóstico Confirmado de COVID-19: Estudo Observacional

Objective: Describe incidental tomographic in the sample, correlating them with risk factors for chest diseases and sociodemographic data. Methods: This is a retrospective and observational study covering 162 patients admitted to the COVID sector of the HU/UFJF, from April 1, 2020, to July 7, 2021, with a confirmed laboratory diagnosis of COVID-19. The variables were described in absolute and relative frequencies. The comparison of the correlation between the outcome variable (the tomographic findings) for independent samples was performed using Pearson's chi-square test (without correction) or Fisher's test when relevant. Results: Of the 162 patients, 15.4% had a solitary pulmonary nodule; 14.8% had multiple pulmonary nodules; 1.8%, lung mass; 3.1%, mediastinal mass, and 9.3% had mediastinal adenomegaly. Findings such as excavations, pleural effusion, emphysema, PTE, pneumothorax, chronic interstitial disease, cavitation, aneurysms, and significant atheromatosis, classified in this study in the "Other" category showed impressive results, with an overall prevalence of 81.5%. This study demonstrated that 34% of patients had two or more types of incidental CT findings and that 88.3% of patients had at least some type of incidental CT finding. Conclusion: The pandemic of SARS-CoV-2 infections has brought a series of challenges and lessons learned to healthcare teams around the world. The massive implementation of highly sensitive diagnostic methods, such as chest tomography, ends up bringing an additional challenge, which is to deal with incidental findings, making good clinical reasoning necessary to avoid unnecessary investigations and not leave without diagnosis and treatment of diseases in early and asymptomatic stages (AU)

Objetivo: Descrever os achados incidentais tomográficos na amostra, correlacionando-os com fatores de risco para doenças torácicas e dados sociodemográficos. Método: Trata-se de um estudo retrospectivo e observacional, abrangendo 162 pacientes admitidos no setor COVID do HU/UFJF, no período de 1º de abril de 2020 a 7 de julho de 2021, com diagnóstico laboratorial confirmado de COVID-19. As variáveis em frequências absolutas e relativas foram descritas. A comparação da correlação entre a variável desfecho (os achados tomográficos) para amostras independentes foi realizada por meio do teste qui-quadrado de Pearson (sem correção) ou Fisher quando pertinente. Resultado: Dos 162 pacientes, 15,4% apresentavam nódulo pulmonar solitário; 14,8%, nódulos pulmonares múltiplos; 1,8%, massa pulmonar; 3,1%, massa mediastinal e 9,3%, adenomegalia mediastinal. Achados como escavações, derrame pleural, enfisema, TEP, pneumotórax, intersticiopatia crônica, cavitação, aneurismas e ateromatose significativa, classificados, neste estudo, na categoria "Outros", apresentaram resultados impactantes, com uma prevalência global de 81,5%. Este estudo demonstrou que 34% dos pacientes apresentavam 2 ou mais tipos de achados tomográficos incidentais e que 88,3% dos pacientes apresentavam pelo menos algum tipo de achado tomográfico incidental. Conclusão: A pandemia de infecções pelo SARS-CoV-2 trouxe uma série de desafios e aprendizados para as equipes de saúde em todo o mundo. A realização maciça de métodos diagnósticos de elevada sensibilidade, como a tomográfica de tórax, acaba por trazer um desafio adicional, que é o de lidar com achados incidentais, fazendo-se necessário um bom raciocínio clínico para evitar investigações desnecessárias e não deixar sem diagnóstico e tratamento doenças em fases iniciais e assintomáticas

Patrón inflamatorio de las vías aéreas en pacientes fumadores con enfermedad pulmonar obstructiva crónica / Inflammatory pattern of the airways in COPD smokers

Introducción: La enfermedad pulmonar obstructiva crónica cursa con un patrón inflamatorio en la vía aérea que incluye neutrófilos, macrófagos, linfocitos, los cuales se pueden obtener mediante un cepillado bronquial citológico. Objetivos: Identificar patrón inflamatorio según células inflamatorias presentes en la vía aérea, mediante el cepillado bronquial citológico e índice tabáquico de paquetes/año en pacientes con enfermedad pulmonar obstructiva crónica. Métodos: Se realizó un estudio descriptivo transversal en pacientes con enfermedad pulmonar obstructiva crónica, que concurrieron al Hospital Neumológico Benéfico-Jurídico, en el período comprendido de junio de 2018 a junio de 2019, con indicación para la realización de fibrobroncoscopía con cepillado bronquial. Resultados: El 53,1 por ciento de los pacientes corresponden al sexo masculino. Un 46,1 por ciento presentó un índice tabáquico de paquetes/año entre 21-40. Predominaron las criptas y estrías como hallazgos broncoscópicos con un 51 por ciento y 40,8 por ciento respectivamente en pacientes con índice paquetes/año mayor que 40. De los pacientes con índice paquetes/año mayor de 40 (13 para un 26,5 por ciento) presentaron hiperplasia de células basales. El 46,9 por ciento de los pacientes presentaron un patrón inflamatorio neutrofílica. Conclusiones: Se identificaron a los pacientes con EPOC que presentaron patrón inflamatorio neutrofílica en la vía aérea y elevado índice tabáquico y desde el punto de vista broncoscópico tienen varios hallazgos que sugieren cronicidad(AU)

Introduction: Chronic obstructive pulmonary disease presents with an inflammatory pattern in the airway that includes neutrophils, macrophages, and lymphocytes, which can be obtained by cytological bronchial brushing. Objectives: To identify inflammatory pattern according to inflammatory cells present in the airway, through cytological bronchial brushing and smoking rate of packs/year in patients with chronic obstructive pulmonary disease. Methods: A cross-sectional descriptive study was carried out in patients with chronic obstructive pulmonary disease, who attended Benefico-Jurídico Pneumological Hospital, from June 2018 to June 2019, with an indication for fiberoptic bronchoscopy with bronchial brushing. Results: 53.1percent of the patients correspond to the male sex. 46.1percent ad a smoking rate of packs/year between 21-40. Crypts and striae predominated as bronchoscopic findings with 51percent and 40.8percent respectively in patients with a pack/year index greater than 40. Patients with a pack/year index greater than 40 (13 for 26.5percent) showed basal cell hyperplasia. 46.9percent of the patients had a neutrophilic inflammatory pattern. Conclusions: Patients with COPD who had a neutrophilic inflammatory pattern in the airway and high smoking index were identified, and from the bronchoscopic point of view they have several findings that suggest chronicity(AU)

Histogram analysis in the differentiation between adrenal adenomas and pheochromocytomas: the value of a single measurement / Análise por histograma para diferenciação entre adenomas da adrenal e feocromocitomas: o valor de uma medida única

Abstract Objective: To assess the diagnostic accuracy of histogram analysis on unenhanced computed tomography (CT) for differentiating between adrenal adenomas and pheochromocytomas (PCCs). Materials and Methods: We retrospectively identified patients with proven PCCs who had undergone CT examinations between January 2009 and July 2019 at one of two institutions. For each PCC, we selected one or two adenomas diagnosed within two weeks of the date of diagnosis of the PCC. For each lesion, two readers scored the size, determined the mean attenuation, and generated a voxel histogram. The 10th percentile (P10) was obtained from the conventional histogram analysis, as well as being calculated with the following formula: P10 = mean attenuation - (1.282 × standard deviation). The mean attenuation threshold, histogram analysis (observed) P10, and calculated P10 (calcP10) were compared in terms of their diagnostic accuracy. Results: We included 52 adenomas and 29 PCCs. The sensitivity, specificity, and accuracy of the mean attenuation threshold were 75.0%, 100.0%, and 82.5%, respectively, for reader 1, whereas they were 71.5%, 100.0%, and 81.5%, respectively, for reader 2. The sensitivity, specificity, and accuracy of the observed P10 and calcP10 were equal for both readers: 90.4%, 96.5%, and 92.6%, respectively, for reader 1; and 92.3%, 93.1%, and 92.6%, respectively, for reader 2. The increase in sensitivity was significant for both readers (p = 0.009 and p = 0.005, respectively). Conclusion: For differentiating between adenomas and PCCs, the histogram analysis (observed P10 and calcP10) appears to outperform the mean attenuation threshold as a diagnostic criterion.

Resumo Objetivo: Avaliar a acurácia diagnóstica da análise por histograma na tomografia computadorizada (TC) sem contraste para a diferenciação entre adenomas adrenais e feocromocitomas (FCCs). Materiais e Métodos: Identificamos, retrospectivamente, pacientes com diagnóstico de FCC confirmado que foram submetidos a exames de TC entre janeiro de 2009 e julho de 2019 em duas instituições distintas. Para cada FCC, selecionamos um ou dois adenomas diagnosticados em até duas semanas da data do diagnóstico do FCC. Para cada lesão, dois leitores pontuaram o tamanho, determinaram a atenuação média e geraram um histograma com os voxels das imagens. O percentil 10 (P10) foi obtido a partir da análise convencional do histograma, além de ser calculado com a seguinte fórmula: P10 = atenuação média - (1,282 × desvio-padrão). O limiar de atenuação média, o P10 da análise por histograma (P10 observado) e o P10 calculado (P10calc) foram comparados em termos de acurácia diagnóstica. Resultados: Foram incluídos 52 adenomas e 29 FCCs. A sensibilidade, especificidade e acurácia do limiar de atenuação média foram de 75,0%, 100,0% e 82,5% para o leitor 1, respectivamente, e de 71,5%, 100,0% e 81,5% para o leitor 2, respectivamente. A sensibilidade, especificidade e acurácia do P10 observado e do P10calc foram idênticas para os dois leitores: 90,4%, 96,5% e 92,6%, respectivamente, para o leitor 1; e 92,3%, 93,1% e 92,6%, respectivamente, para o leitor 2. O aumento da sensibilidade foi significativo para ambos os leitores (p = 0,009 e p = 0,005, respectivamente). Conclusão: Para a diferenciação entre adenomas e FCCs, a análise por histograma (P10 observado ou P10calc) parece superar o limiar de atenuação média como critério diagnóstico.

There was a decrease in all morphometric variables in both kidneys, highlighting the thickness of the renal cortex. Conclusions: there was a relationship between hypertension, diabetes mellitus and obesity with renal morphometric variables.

Factors Affecting Under-Five Mortality Rate (U5MR) in India- National Family Health Survey (NFHS) 5 Factsheet What It Speaks?

Introduction: In developing countries various factors lead to Under-5 Mortality and irreversible losses which can be prevented by proper measures take on factors affecting to it. Objective: This study was conducted to analyse the changing trends of Under-5 Mortality in India. The new National Family Health Survey (5th round) which was published recently came up with several new findings, which were both encouraging and disheartening and also one of the major Sustainable Development Goals.Method: A secondary data analysis was conducted of NFHS factsheets to study the U5MR in India. The indica-tors which had a correlation either positive or negative with the Under-five mortality rate were included.Result- When we look at the result, few states' performance is encouraging because they have shown some of the best declines. Correlation was found between dependant variable that is U5MR which is a dependent vari-able and several independent variables which concluded that factors like Women literacy, Men literacy, Breastfeeding, Nutritional insufficiencies, Caesarean delivery, ANC visits and IFA consumptions are negatively associated withU5MR. Conclusion: Various steps have been taken in order to improve our healthcare sector since independence, every government had their fair share of contribution, that’s the reason why we are this stage. Now it’s time to increase efforts with targeted interventions to solve this problem and complete our commitment towards the SDGs.

Tratamento percutâneo de origem anômala de coronária direita com trajeto maligno em paciente com morte súbita abortada / Percutaneous treatment of anomalous origin of the right coronary artery with malignant course in a patient with aborted sudden death

Anomalias coronarianas são menos frequentes em relação às doenças coronarianas adquiridas, como a aterosclerose, e têm sido implicadas como causa de eventos cardiovasculares. Este relato de caso descreve um achado incidental por angiografia de coronária direita anômala com origem no seio coronariano esquerdo e trajeto intra-arterial, após episódio de morte súbita abortada. A análise do Heart Team indicou como melhor tratamento a abordagem percutânea com implante de stent farmacológico em origem de coronária direita, procedimento este que foi realizado com sucesso. Este relato de caso e estudos recentes têm demonstrado que o tratamento percutâneo de anomalias coronarianas é uma opção segura para pacientes selecionados, levando em consideração quadro clínico, estudo anatômico e capacitação da equipe de hemodinâmica

Coronary anomalies are less frequent than acquired coronary diseases, such as atherosclerosis, and have been implicated as a cause of cardiovascular events. This case report describes an incidental finding on angiography of an anomalous right coronary artery with origin in the left coronary sinus and an intra-arterial course, after an episode of aborted sudden death. The Heart Team analysis indicated a percutaneous approach with drug-eluting stent implantation at the origin of the right coronary artery as the best treatment, and the procedure was successfully performed. This case report and recent studies have demonstrated percutaneous treatment of coronary anomalies is a safe option for selected patients, considering clinical presentation, anatomy study, and training of the cath lab team

Hallazgos incidentales en cirugía abdominal: masas y sarcomas retroperitoneales / Incidental findings in abdominal surgery: Retroperitoneal masses and sarcomas

Introducción. El retroperitoneo es una estructura que se extiende desde el diafragma hasta la pelvis, está delimitado adelante por el peritoneo parietal, atrás y a los lados por la fascia transversalis y se divide en 9 compartimientos. Se pueden encontrar lesiones primarias o secundarias, cuya evolución clínica varía desde un curso indolente hasta rápidamente progresivo, tanto local como a distancia. Su enfoque, desde el hallazgo hasta el tratamiento, es fundamental para el desenlace oncológico. Objetivo. Analizar la evaluación, el diagnóstico y el tratamiento de las masas retroperitoneales halladas incidentalmente y brindar un algoritmo de manejo. Métodos. Se hizo búsqueda en bases de datos como PubMed y MedicalKey de literatura referentes a tumores retroperitoneales, su diagnóstico y enfoque terapéutico, con el fin de presentar una revisión sobre el abordaje de las masas retroperitoneales y dar nuestras opiniones. Resultados. Se revisaron 43 referencias bibliográficas internacionales y nacionales, y se seleccionaron 20 de ellas, de donde se obtuvieron datos actualizados, recomendaciones de guías internacionales y experiencias nacionales, con lo cual se estructuró este manuscrito. Conclusiones. Las masas retroperitoneales abarcan un espectro de patologías que establecen un reto diagnóstico por su origen embriológico, localización y baja frecuencia. El diagnostico histológico es de vital importancia desde el inicio, para conocer la evolución natural de la enfermedad, y el manejo multidisciplinario en centros de referencia es fundamental para impactar en los desenlaces oncológicos. Existen variadas modalidades terapéuticas, como quimioterapia, radioterapia y resección quirúrgica con estándares oncológicos

Introduction. The retroperitoneum is an structure that extends from the diaphragm to the pelvis, bounded anteriorly by the parietal peritoneum, posteriorly and laterally by the transversalis fascia, and it is divided into 9 compartments. We can find primary or secondary lesions whose clinical evolution varies from an indolent course to a rapidly progressive one, both local and distant. Its approach from discovery to diagnosis and treatment is essential for the oncological outcomes. Objective. To analyze the evaluation, diagnosis and treatment of incidental retroperitoneal masses according to their origin and to provide a management algorithm. Methods. An updated literature search was carried out in databases such as PubMed and Medical Key on retroperitoneal tumors, therapeutic approach and diagnosis, obtaining national and international information to carry out a review article on the approach to retroperitoneal masses.Results. Forty-three international and national bibliographic references were reviewed, based on 20 updated data, recommendations from international guidelines and national experiences were obtained, with which a review and opinion manuscript was structured.Conclusions. Retroperitoneal masses cover a spectrum of pathologies that establish a diagnostic challenge due to their embryological origin, location and low frequency. Histological diagnosis is of vital importance from the beginning to know the natural evolution of the disease and multidisciplinary management in reference centers is essential to impact oncological outcomes. There are many therapeutic modalities from chemotherapy, radiotherapy and surgical resection with oncological standards

Estudio clínico-epidemiológico de Enfermedad de Kawasaki antes y durante la pandemia por COVID-19. IAHULA. 2010-2022

Introducción: La Enfermedad de Kawasaki (EK) es una vasculitis sistémica de vasos medianos, que afecta preferentemente a niños menores de 5 años. En su etiología desconocida, se propone predisposición genética e interacción con agentes respiratorios virales, incluyendo el coronavirus estacional. Se ha informado un aumento notable en la incidencia de esta enfermedad en la pandemia COVID-19. Objetivos: El objetivo fue comparar las características clínico-epidemiológicas de la EK, antes y durante la pandemia COVID-19, en el IAHULA, Mérida, Venezuela (2010 - 2022). Material y Método: Se diseñó un estudio comparativo, de series de casos clínicos, una cohorte comprendió entre el 01/01/2010 y el 10/03/2020; y la otra del 11/03/2020 al 30/04/2022, se valoraron aspectos demográficos, clínicos, ecocardiográficos y tratamiento. Se analizó la distribución de frecuencias, medias, desviación estándar, pruebas Chi-cuadrado o t de Student. Resultados: Encontramos un total de cuarenta y nueve pacientes (n=49, 100 %), veintitrés (n=23, 46,9 %) con EK completa predominaron durante pandemia (68,8 % vs 63,6 %, p=0,034), presentaron en mayor proporción conjuntivitis bulbar no exudativa, leucocitosis y elevación de la proteína C reactiva (PCR), el derrame pericárdico resaltó como hallazgo cardiovascular; todos tuvieron IgG SARSCoV- 2 positiva, al igual que 2 con prueba antigénica. La media de la edad fue de 3,2±3,1 años. Los menores de 5 años fueron los más afectados. Siete presentaron otros virus desencadenantes de la expresión de EK prepandemia. Conclusión: El SARS-CoV-2 pudo actuar como disparador del aumento de EK completa en pandemia; administrar precozmente inmunoglobulina, evaluar y el seguimiento cardiovascular respectivo son fundamentales.

Introduction: Kawasaki disease (KD) is a systemic vasculitis of medium vessels, which preferentially affects children under 5 years of age. In its unknown etiology, genetic predisposition, and interaction with viral respiratory agents, including the seasonal coronavirus, are proposed. A marked increase in the incidence of this disease has been reported in the COVID-19 pandemic. Objectives: The objective was to compare the clinical-epidemiological characteristics of KD, before and during the COVID-19 pandemic, at IAHULA, Mérida, Venezuela (2010 - 2022). Material and Methods: A comparative study was designed, of series of clinical cases, a cohort between 01/01/2010 and 03/10/2020; and the other from 03/11/2020 to 04/30/2022, demographic, clinical, echocardiographic and treatment aspects were assessed. The distribution of frequencies, means, standard deviation, Chi-Square or Student's t tests were analyzed. Results: We found a total of forty-nine patients (n=49, 100 %), twenty-three (n=23, 46.9 %) with complete KD predominated during the pandemic (68.8 % vs 63.6 %, p=0.034), they presented a higher proportion of nonexudative bulbar conjunctivitis, leukocytosis and elevated C-reactive protein (CRP), pericardial effusion stood out as a cardiovascular finding in 20 % of cases; all had positive SARS-CoV-2 IgG, as did 2 with antigenic testing. The mean age was 3.2±3.1 years. Children under 5 years of age were the most affected. Seven had other viruses that triggered pre-pandemic EK expression. Conclusions: SARS-CoV-2 could have acted as a trigger for the increase in complete KD in a pandemic; early administration of immunoglobulin, evaluation and respective cardiovascular follow-up are essential.

Study of portal vein diameter by ultrasound and its association with endoscopic findings in patients with liver cirrhosis

Background: The major cause of morbidity and mortality in patients with portal hypertension is due to oesophageal varices. Upper gastrointestinal endoscopy is considered best to detect varices earlier. It’s an invasive tool which is expensive and increased financial burden among patients. Hence this study is undertaken to find non-invasive indicators of oesophageal varices in cirrhosis patients with portal hypertension and to establish the role of portal vein diameter determined by ultrasonography in predicting the oesophageal varices. Aim and objectives: To detect non-invasive indicators of oesophageal varices in chronic liver disease, to determine the relation between oesophageal varices on upper gastrointestinal endoscopy and portal vein diameter, to determine other non-invasive parameters to identify oesophageal varices. Materials and methods: A cross sectional study on 45 patients, who were diagnosed to have chronic liver disease and are being presented to outpatient department and were admitted in Malla Reddy Institute of Medical Sciences, Suraram over a period of one year under department of general medicine. All the patients with chronic liver disease who underwent upper gastrointestinal endoscopy are included in the study. Results: 45 patients with cirrhosis of liver were included in the study, among which 32 were males and 13 were females with a mean age group of 46 years. On upper gastrointestinal endoscopy 87% of patients had oesophageal varices while other 13% of patients were normal. Mean portal vein diameterwas 13.8 mm and has a positive linear correlation with p<0.01 and positive predictive value of 95.25%. Majority of patients belonged to the platelet count group of 50,000 to 1lakh and its inversely co related to the severity of varices. Majority of patients with oesophageal varices had moderate splenomegaly. Conclusion: Ultrasonography of portal vein diameter and spleen size along with thrombocytopenia are reliable, inexpensive and easily reproducible non-invasive tool in predicting the presence of oesophageal varices and hence can identify the patients who require endoscopy on a prophylactic basis.

Critical Congenital Heart Disease Sadly Diagnosed at Autopsy in Calabar, South-South Nigeria

Congenital heart disease (CHD) is the most common type of birth defect causing more deaths in the first year of life than any other birth defect. Medical practice in a third-world country is faced with numerous challenges, created by poor health facilities and the unavailability of basic imaging studies at the community level where the majority of the poor resides. We present a case series of 4 neonates with a ratio of 1: 3 admitted into the neonatology unit of the University of Calabar Teaching Hospital, Calabar, Nigeria. Two of the patients were delivered at home by a traditional birth attendant via spontaneous vertex delivery and the rest two were booked cases in a private and obstetric unit of the University of Calabar Teaching Hospital. Their age ranged were 18 hours to 27 days of life and their common presentation were poor sucking, difficulty in breathing, central cyanosis and failure to thrive. A fetal echocardiogram was carried out for one of the cases and there was strong clinical suspicion of congenital heart disease but the precise type is unknown. The other three could not afford the necessary investigations required. They were all oxygen-dependent till death. Pathologic-anatomic findings showed a rare Critical congenital heart defect of the univentricular heart chamber of various types for the three cases and a case of TGA. The Immediate cause of death for all four cases was congestive cardiac failure.

Correlation Between Laboratory Findings and Clinical Severity among the COVID-19 Patients in the Tertiary Care Centre

Background : Coronavirus is a highly infectious novel virus we are in urge to know more about their clinical characteristics and laboratory findings for the characterization and selection of treatment protocol. Methods : Prospective, single centre study. Two months data was collected, clinical characteristics data from patient case sheet and the laboratoryvalues from the Hospital Information System (HIS) for the month of July and August 2020. Results : Of 462 patients, 55 (11.9%) are falls under asymptomatic category, 194 (42%) are in mild category, 167 (36.1%) are in moderate category and 46 (10%) in severe category. Fever 230 (49.8%) and cough 211 (45.7%) was most common clinical symptom with p value < 0.01. Non-severe vs severe, 340 (73.6%) and 201 (43.5%) showed decreased in eosinophil count and absolute eosinophil count, 125 (27.1%) and 80 (17.3%) patient showed decrease in lymphocyte count and absolute lymphocyte count, 200 (43.3%) showed increase in neutrophil count with a significance of p value >0.05. 186 (40.3%) patients had one or more co-morbidities. Laboratory findings between Asymptomatic VS symptomatic, showed significance changes in neutrophil, lymphocyte, Aspartate aminotransferase, Alkaline phosphatase, globulin values (p value <0.05). Conclusion : Clinical severity categorization at the time of admission was very helpful for the treating doctors in proper understanding of disease progression and appropriate treatment of the patient. Presence of co-morbidity, abnormal laboratory values, old age group patients, higher Computed Tomography score, higher mortality rate are seen more in patients who were in clinical severity grade severe category than in non-severe category patients.
