Rare case of mantle cell lymphoma of the lacrimal sac

ABSTRACT Mantle cell lymphoma of the ocular and periorbital regions is extremely rare but should be considered in the differential diagnosis of lesions affecting the periorbital tissues. In this study, we present a rare case of mantle cell lymphoma of the lacrimal sac in a 65-year-old male presenting with a mass in the lacrimal sac region and epiphora. After clinical examinations and imaging studies, the mucocele was misdiagnosed. Considering the unexpected findings during external dacryocystorhinostomy, a frozen biopsy was performed, which confirmed the diagnosis of lymphoma.

ABSTRACT A patient presented with corneoscleral thinning five months after the treatment of suspected ocular squamous surface neoplasia with mitomycin-C and interferon. For tectonic and aesthetic purposes, we decided to perform lamellar corneoscleral transplantation. The approach used established new tectonic support and corneal homeostasis. This technique might be an option in similar cases.

Clinical, epidemiological, and care profile of hospitalized patients with retinoblastoma in Brazil

ABSTRACT Purpose: To describe the epidemiological and clinical profile of hospitalized patients with retinoblastoma in Brazil. Methods: Using data from the Hospital Cancer Registry of the Instituto Nacional de Câncer, patients with the morphological codes of retinoblastoma who were diagnosed between 2000 to 2018, aged 0-19 years, and followed up in registered hospitals (analytical cases) were selected. The relative and absolute frequencies of demographic, clinical, diagnostic, therapeutic, and outcome variables were described. Hospital performance indicators were calculated and compared between hospitals qualified and not qualified to treat pediatric oncology cases and between hospitals with different case volumes (<20, 20-75, >75 cases). Results: Of the 2,269 identified analytical cases from 86 institutions, 48% were from the Southeast, 54% were male, and 66% were aged <4 years. The proportion of missing data (NA) was too high for several variables. Approximately 84% of the patients were from the public health system, 40% had a positive family history, and 88% had unilateral involvement. The first treatment included surgery in 58.3% of the patients (NA=2), Approximately 36.6% of these patients achieved complete remission, 10.8% achieved partial remission, and 12.7% died (NA=59%). Hospital performance indicators were within the target in >90% of the patients. The median time between the first appointment and diagnosis (6 days, interquartile range [IQR] 1-14) was significantly lower and the median time to death was longer (343 days, IQR, 212-539) in high-volume hospitals (>75 cases) than in medium- and low-volume hospitals. Conclusions: Despite the high proportion of missing data, we found that the delay in diagnosis is due to prehospital factors. Additionally, there is a need for educational programs for healthcare professionals and families that emphasize early identification and referral to specialized centers. Future studies should focus on the impact of Hospital Cancer Registry data completeness on outcomes, causes of delay in diagnosis, regional inequalities, and barriers to accessing specialized services.

Tratamiento de paciente clase III esqueletal por hipoplasia maxilar con canino superior retenido / Treatment of skeletal class III patient due to maxillary hypoplasia with retained upper canine

La maloclusión clase III esqueletal por hipoplasia maxilar puede provocar la retención de algunas piezas dentales, ocupando los caninos superiores el tercer lugar de los dientes más afectados; por lo que es necesario el trabajo interdisciplinario con otras especialidades odontológicas para su correcto abordaje quirúrgico. Mientras que, para la corrección de la hipoplasia maxilar, el expansor Hyrax es el tratamiento ortopédico más utilizado en pacientes con crecimiento remanente. Se presenta caso clínico de paciente femenina de 14 años, clase III esqueletal por hipoplasia maxilar, biotipo mesofacial, perfil cóncavo, mordida cruzada anterior y posterior unilateral izquierda con canino superior derecho retenido. Los principales objetivos fueron: corregir la mordida cruzada y traccionar el canino retenido a su correcta posición. Al finalizar el tratamiento se eliminó la mordida cruzada y se logró la expansión palatina, incorporando así, el canino retenido en el arco dentario. En conclusión, el correcto diagnóstico, el adecuado plan de tratamiento y la atención temprana de la paciente fueron factores indispensables ya que proporcionaron un pronóstico favorable y un tratamiento conservador, evitando futuras complicaciones y tratamientos invasivos.

Skeletal class III malocclusion due to maxillary hypoplasia can cause the retention of some teeth, with the upper canines occupying the third place of the most affected teeth; therefore, interdisciplinary work with other dental specialties is necessary for its correct surgical approach. Likewise, for the correction of maxillary hypoplasia, the Hyrax expander is the most commonly used orthopedic treatment in patients with remnant growth. We present a clinical case of a 14-year-old female patient, skeletal class III due to maxillary hypoplasia, mesofacial biotype, concave profile, left unilateral anterior and posterior crossbite with retained right upper canine. The main objectives were: to correct the crossbite and pull the retained canine to its correct position. At the end of the treatment, the crossbite was eliminated and palatal expansion was achieved, thus incorporating the canine retained in the dental arch. In conclusion, the correct diagnosis, the adequate treatment plan and the early care of the patient were indispensable factors since they pro-vided a favorable prognosis and conservative treatment, avoiding future complications and invasive treatments.

Hemi-craneotomía y hemimandibulectomía izquierda como tratamiento del ameloblastoma multiquístico, manejo multidisciplinario. Reporte de caso / Left hemi-craneotomy and hemimandibulectomy as treatment of multicystic ameloblastoma, multidisciplinary management. Case report

El ameloblastoma multiquístico, una neoplasia odontogénica de crecimiento lento, pero comportamiento agresivo, suele manifestarse en la mandíbula, generando deformidades faciales, pérdida dentaria y desplazamiento de tejidos adyacentes. Este estudio tiene como objetivo describir el tratamiento quirúrgico multidisciplinario del ameloblastoma multiquístico en una localización inusual, destacando el compromiso de estructuras vitales y los estudios complementarios necesarios para un diagnóstico preciso. Se presenta el caso de un paciente masculino con una lesión en la hemicara izquierda, que se había desarrollado durante aproximadamente ocho meses, abarcando desde la región temporoparietal hasta la región maseterina ipsilateral. La evaluación clínica y radiológica inicial sugirió la posibilidad de un ameloblastoma multiquístico, confirmado posteriormente mediante biopsia. Como parte del equipo multidisciplinario del Hospital San Vicente Fundación de Medellín, se optó por una resección quirúrgica radical, que incluyó hemi-craneotomía y hemi-mandibulectomía, seguida de una reconstrucción exitosa. Se señala la importancia de un abordaje coordinado entre cirujanos maxilofaciales, estomatólogos y otros especialistas, así como la relevancia de los estudios complementarios para determinar el curso terapéutico óptimo. La cirugía reconstructiva demostró ser efectiva tanto en la restauración funcional como estética, aunque destaca los desafíos inherentes a la gestión de localizaciones poco comunes de esta enfermedad.

Multicystic ameloblastoma, a slow-growing but aggressive odontogenic neoplasm, usually manifests in the mandible, causing facial deformities, tooth loss and displacement of adjacent tissues. This study aims to describe the multidisciplinary surgical management of multicystic ameloblastoma in an unusual location, highlighting the involvement of vital structures and the complementary studies necessary for an accurate diagnosis. We present the case of a male patient with a lesion in the left hemiface, which had developed over approximately eight months, spanning from the temporoparietal region to the ipsilateral maseterine region. Initial clinical and radiological evaluation suggested the possibility of multicystic ameloblastoma, subsequently confirmed by biopsy. As part of the multidisciplinary team of the Hospital San Vicente Fundación de Medellín, a radical surgical resection was chosen, including hemi-craniotomy and hemi-mandibulectomy, followed by successful reconstruction. The importance of a coordinated approach between maxillofacial surgeons, stomatologists and other specialists is emphasized, as well as the relevance of complementary studies to determine the optimal therapeutic course. Reconstructive surgery proved to be effective in both functional and cosmetic restoration, although it highlights the challenges inherent in managing rare locations of this disease.

Alergia a las proteínas de la leche de vaca: proceso diagnóstico. Consenso interdisciplinario de expertos / Cow's milk allergy: diagnostic process. Expert consensus

Las proteínas de la leche de vaca pueden causar alergia alimentaria. Los distintos mecanismos de acción involucrados y la variabilidad clínica según la etapa de la vida pediátrica en la que se manifieste ocasionan dificultades en su abordaje, con riesgo de sub- o sobrediagnóstico. En este proceso, intervienen profesionales de diversas áreas y es recomendable su interacción. Es por ello que el objetivo de este consenso ha sido reflejar el conocimiento actualizado desde la interdisciplina, generando recomendaciones para su correcto diagnóstico. Hemos trabajado con el método de Delphi para sumarle a la evidencia científica, la experiencia proveniente de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología. Pensamos que este enfoque interdisciplinario de trabajo va a resultar de utilidad práctica y promoverá una atención más integral de estos pacientes.

Cow's milk protein can cause food allergy. The different mechanisms of action involved, the clinical variability depending on the stage of pediatric life in which it manifests, leads to difficulties in its approach, with the risk of under- or over-diagnosis. Professionals from various areas intervene in this process and their interaction is recommended. That is why the objective of this consensus has been to reflect the updated knowledge in an interdisciplinary mode, generating recommendations for its correct diagnosis. We have worked with the Delphi method to add to the scientific evidence, the experience from neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology. We think that this interdisciplinary approach will be of practical use and will promote more comprehensive care for these patients.

Reducing delayed detection of isolated cleft palate-related deformity: a call for routine intraoral examination of newborns

Abstract Objective: To provide healthcare professional-friendly practical recommendations for early detection of cleft palate-related deformities in newborns and offer an overview of managing these high-prevalent congenital abnormalities. Source of data: PubMed, SciELO, Lilacs, Cochrane, ScienceDirect, and Scopus databases were reviewed for cleft- and diagnosis-related studies. Summary of the findings: Unfortunately, the global prevalence of delayed detection of cleft palate-related deformities remains unacceptably high, with over a quarter of cleft palates missed at birth. This delayed identification causes physical and psychological distress for patients and families, including feeding challenges and weight faltering. To improve cleft management, it is essential to adopt routine detailed, in-depth intraoral examination immediately after birth. It is recommended not only to finger-assisted palpate the intraoral structures but also to visually inspect the oral cavity from gingiva to uvula using a wooden tongue depressor and light-assisted examination. With timely diagnosis and referral to specialized care, pediatricians, nurses, speech therapists, and plastic surgeons provide life-changing treatments, including health care maintenance, anticipatory guidance, feeding support, primary surgical reconstruction, and age-and condition-specific protocols. Conclusions: Encouraging neonatologists and pediatricians, who are the first to examine new-borns, to actively investigate the intraoral region for cleft palate-related deformities is instrumental in optimizing therapeutic approaches and prioritizing age-phases in treatment. Their crucial role in early detection and referral can lead to transformative outcomes, impacting not only the future of the newborns by facilitating functional integration into society but also yielding positive effects on families and the health system.

Missed opportunities in the prevention and diagnosis of pediatric tuberculosis: a scoping review

Abstract Objectives: Identify potential barriers, delays, and missed opportunities in the prevention and diagnosis of childhood TB. Methods: Scoping review according to the PRISMA extension. The definitions considered for the selection followed the acronym PCC where the population (P) is children under 18years of age with TB disease, the concept (C) refers to missed opportunities for prevention and diagnosis, and context (C) is defined as a diagnosis of TB disease. The authors searched systematically in the databases; VHL/Lilacs, Medline via PubMed, Cochrane, Scopus, and Web of Science, without date or language limitation. Results: Seven studies were included. In developed countries, with low disease burden, the main shortcoming is the delay in diagnosing bacilliferous adults in contact with young children. This problem is concentrated in the portion of the population with socioeconomic vulnerability. In underdeveloped countries, with a high burden of disease, the biggest challenge is tracking children who come into contact with bacilliferous patients. Conclusions: There are still many missed opportunities in the prevention and diagnosis of childhood TB. The positive legacy of the COVID-19 pandemic should be taken advantage of and the encouragement of scientific development in the management of infectious diseases should be taken.

Incorporación de Tecnología Tridimensional mediante Tomografía Microcomputarizada en el Estudio de la Anatomía de Salmónidos: Una Evaluación de Utilidad / Integration of Three-Dimensional Technology through Microcomputed Tomography in the Study of Salmonid Anatomy: A Utility Evaluation

Los salmónidos, durante su desarrollo, pueden experimentar ocasionalmente deformaciones esqueléticas. Para su diagnóstico se emplean diversas metodologías, entre las que se incluyen radiografías, técnicas histológicas, diafanización con tinciones de alizarina y azul de alcián, así como el uso del microscopio electrónico de barrido (SEM), cada una con sus inherentes ventajas y desventajas. Este estudio tuvo como finalidad evaluar y comparar la eficacia de la tomografía microcomputarizada (Micro-CT) para el análisis anatómico, reconstruyendo tridimensionalmente las imágenes y contrastándolas con los resultados obtenidos mediante la técnica de diafanización. Se analizaron las aletas caudales de cinco ejemplares de salmón Oncorhynchus kisutch: dos sujetos a diafanización y tres procesados para análisis mediante Micro-CT utilizando el equipo BRUKER SkyScan 1272. La técnica de Micro-CT demostró superioridad en la resolución de las estructuras óseas, facilitando una exploración detallada de las variaciones morfológicas y la distribución de la densidad mineral. Este enfoque permitió identificar anomalías en la morfología y crecimiento de las últimas vértebras y lepidotriquias dorsales, así como una densidad incrementada en lepidotriquias dorsales malformadas. La mayor resolución proporcionada por la Micro-CT no solo potencia nuestra comprensión de la ontogenia piscícola y su adaptación a ambientes diversos, sino que además inaugura perspectivas innovadoras para el estudio de la evolución de las estrategias locomotoras y las respuestas adaptativas frente a cambios ambientales a través del tiempo.

SUMMARY: During their development, some species of salmonids may occasionally experience skeletal deformations. Several methodologies are currently being used for the diagnosis of such malformations, among which X-rays, histological techniques, diaphanization coupled either with Alizarin Red or Alcian Blue stains, as well as Scanning Electron Microscopy (SEM) can be mentioned. Each one of those methods presents inherent advantages and disadvantages. The purpose of this study was twofold: Firstly, to evaluate and compare the effectiveness of microcomputed tomography (Micro-CT) technology for anatomical analysis, three-dimensionally reconstructing the obtained images; and secondly, to contrast those images with the results obtained through the diaphanization technique. The caudal fins of five specimens of the Oncorhynchus kisutch salmon were analyzed: Two specimens were subjected to diaphanization and three were processed for Micro-CT analysis, using the BRUKER SkyScan 1272 equipment. The Micro-CT technology demonstrated superiority in the resolution of bone structures, facilitating a detailed exploration of morphological variations, as well as the distribution of mineral density. This experimental approach allowed us to identify anomalies in the morphology and growth of the last vertebrae and dorsal lepidotrichiae, as well as an increased mineral density in the malformed dorsal lepidotrichiae. The higher resolution provided by Micro-CT not only enhances our understanding of the fish ontogeny and its adaptation to diverse environments, but also opens innovative perspectives for the study of the evolution of locomotor strategies and adaptive responses to environmental changes.

Effective geriatric management strategies for fatal non-Hodgkin lymphoma: Insights from a case report / Estrategias geriátricas efectivas para el tratamiento del linfoma no Hodgkin mortal: conclusiones de un estudio de caso

This case report delves into the intricate medical history of an 85-year-old male who experienced a myriad of health challenges throughout his years. With a medical history full of conditions, such as stroke, sinus bradycardia, chronic obstructive pulmonary disease, severe pulmonary hypertension, and chronic gastritis, the patient´s health profile is further complicated by prostatic hypertrophy, persistent dorsalgia and lumbalgia, the presence of a thyroid nodule, and a recent onset of hypothyroidism. Among the diverse medical conditions of this patient, our narrative is primarily centered on his latest diagnosis: non-Hodgkin´s lymphoma. Non-Hodgkin´s lymphoma is not just a mere addition to his already complex medical history; it is a malignant neoplasm that shapes worldwide patterns of cancer mortality. The first indicators that led to this discovery were the patient´s complaints of persistent pain in the left lateral neck region associated with dysphagia. This was not an isolated symptom; the patient also reported a month-long history of asthenia, myalgias, weakness around the pelvic girdle, fatigue, and hyporexia, depicting a concerning clinical picture. Advanced diagnostic tools, namely ultrasound and computed tomography, shed light on submaxillary and cervical adenopathies. To corroborate such findings and get a definitive diagnosis of malignancy, a fine-needle aspiration was advised. Through this case, we aim not only to describe a clinical scenario but to highlight the challenges involved in the diagnosing and treatment of non-Hodgkin ´s lymphoma, especially in elderly patients. The overlap of multiple comorbidities adds further complexity to the scene, demanding meticulous care and expertise. This report serves as an educational tool for oncology experts, as well as testimony to the complexities of patient care in the oncology diagnostic and treatment setting.

Este reporte de caso se centra en el intricado historial médico de un varon de 85 años que experimenta una miriada de problemas de salud a lo largo de sus años. Con un historial médico lleno de afecciones, como accidente cerebrovascular, bradicardia sinusal, enfermedad pulmonar obstructiva crónica, hipertensión pulmonar grave y gastritis crónica, el perfil de salud del paciente se complica aún más por la presencia de hipertrofia prostática, dorsalgia y lumbalgia persistentes, la presencia de un nódulo tiroideo y el reciente diagnóstico de hipotiroidismo. Entre las diversas afecciones de este paciente, nuestra narración se centra principalmente en su último diagnóstico: linfoma no Hodgkin. El linfoma no hodgkiniano no es un mero añadido a su ya complejo historial médico; es una neoplasia maligna que configura las tendencias de mortalidad por cáncer a nivel mundial. Los primeros indicadores que llevaron a este descubrimiento fueron las quejas del paciente por dolor persistente en la región lateral izquierda del cuello, asociado a disfagia. No se trataba de un síntoma aislado, ya que el paciente también refería desde hacía un mes astenia, mialgias, debilidad alrededor de la cintura pélvica, fatiga e hiporexia, lo que describía un cuadro clínico preocupante. Las herramientas diagnósticas avanzadas, a saber, la ecografía y la tomografía computarizada, arrojaron luz sobre las adenopatías submaxilares y cervicales. revelaron sobre las adenopatías submaxilares y cervicales. Para corroborar tales hallazgos y obtener un diagnóstico definitivo de malignidad, se aconsejó una aspiración con aguja fina. A través de este caso, pretendemos no sólo describir un escenario clínico, sino resaltar los retos que implica el diagnóstico y tratamiento del linfoma no Hodgkin, especialmente en pacientes de edad avanzada. La superposición de múltiples comorbilidades añade mayor complejidad al escenario, exigiendo una atención meticulosa y experiencia. Este informe sirve como herramienta educativa para los expertos en oncología, así como testimonio de las complejidades de la atención al paciente en el entorno del diagnóstico y el tratamiento oncológico.

Apendicectomía en pacientes con situs inversus: Serie de tres casos con manejo laparoscópico / Appendectomy in patients with situs inversus: Three cases series with laparoscopic approach

Introducción. La transposición de los órganos debido al situs inversus (SI) es una rara afección que dificulta el diagnóstico de la apendicitis aguda. Esta condición hace que la sintomatología del paciente y los hallazgos al examen físico puedan ser atípicos, lo que demanda el uso de imágenes para la confirmación diagnóstica en la mayoría de los casos. Métodos. Se describieron tres casos de apendicitis en pacientes con diagnóstico de situs inversus. Dos de ellos tenían el antecedente conocido, mientras el tercer caso fue diagnosticado de forma intraoperatoria. Resultados. En dos pacientes se decidió llevar a cirugía vía laparoscópica sin imágenes diagnósticas adicionales. Los pacientes evolucionaron de manera satisfactoria. Conclusión. Siempre se debe considerar la apendicitis dentro de los diagnósticos diferenciales en los pacientes con dolor en fosa ilíaca izquierda. Es fundamental diagnosticar y tratar la apendicitis de manera efectiva para minimizar las complicaciones asociadas. La importancia de la anamnesis y la sospecha clínica del examinador son vitales en estos casos, que se pueden confirmar con las imágenes diagnósticas. Pueden existir casos en donde la condición clínica del paciente no permita la realización de estudios diagnósticos por imágenes; esto apoya cada vez más el uso del abordaje laparoscópico. Se recomienda considerar el abordaje laparoscópico en primera instancia, ya que nos permite la confirmación diagnóstica de situs inversus totalis en caso de que el antecedente sea desconocido y facilita el manejo oportuno de la urgencia.

Introduction. Organ transposition due to situs inversus (SI) is a rare condition that makes the diagnosis of acute appendicitis difficult. This condition entails that the patient' symptoms and physical examination findings may be atypical, which requires the use of images for diagnostic confirmation in most cases. Clinical cases. Three cases of appendicitis in patients diagnosed with situs inversus are described. Two of them had a known medical history, while the third case was diagnosed intraoperatively. Results. In two patients it was decided to undergo laparoscopic surgery without additional diagnostic images. The patients progressed satisfactorily. Conclusion. Appendicitis should always be considered in the differential diagnoses in patients with pain in the left iliac fossa. It is essential to diagnose and treat appendicitis effectively to minimize associated complications. The importance of the anamnesis and the examiner's clinical suspicion are vital in these cases, which can be confirmed with diagnostic images. There may be cases where the patient's clinical condition does not allow diagnostic imaging studies to be performed, increasingly supports the use of the laparoscopic approach. It is recommended to consider the laparoscopic approach in the first instance, since it allows us to confirm the diagnosis of situs inversus totalisin case the history is unknown and facilitates timely management of the emergency.

Tumor sólido pseudopapilar de páncreas. Reporte de caso / Solid pseudopapillary tumor of the pancreas. Case report

Introducción. La neoplasia sólida pseudopapilar de páncreas, también conocida como tumor de Frantz, es una patología poco frecuente, que comprende menos del 3 % de los tumores pancreáticos, y la mayor incidencia se observa en mujeres jóvenes entre la segunda y tercera década de la vida. Su etiología es desconocida. El tratamiento de elección es la resección quirúrgica sin linfadenectomía cuando se encuentra bien localizado. Inclusive aún cuando hay evidencia de metástasis o invasión local, el manejo quirúrgico sigue siendo el tratamiento de elección. Caso clínico. Mujer de 24 años de edad, con masa abdominal palpable, dolorosa, de tres semanas de evolución. La tomografía computarizada mencionó como presunción diagnóstica un tumor de origen pancreático. En la laparotomía se encontró una masa dependiente del cuerpo del páncreas. Se realizó pancreatectomía distal radical con esplenectomía y omentectomía parcial en bloque. Resultados. Durante la cirugía no se presentaron complicaciones y hasta el sexto mes de seguimiento, la evolución fue adecuada y sin recidiva tumoral. Conclusiones. Ante la presencia de masa abdominal, con compromiso pancreático documentado por tomografía computarizada, se debe considerar el diagnóstico de neoplasia sólida pseudopapilar de páncreas, o tumor de Frantz. El tumor de Frantz es una entidad poco frecuente que generalmente se diagnostica de forma incidental o por síntomas inespecíficos en estadios avanzados. El diagnóstico y manejo de esta neoplasia representa un reto y la resección quirúrgica continúa siendo el tratamiento indicado.

Introduction. Solid pseudopapillary neoplasia of the pancreas, also known as Frantz tumor, is a rare pathology, comprising less than 3% of pancreatic tumors, and the highest incidence is observed in young women between the second and third decades of life. Its etiology is unknown. The treatment of choice is surgical resection without lymphadenectomy when it is well located. Even when there is evidence of metastasis or local invasion, surgical management remains the treatment of choice. Clinical case. A 24-year-old woman presented with a palpable, painful abdominal mass of three weeks' duration. The computed tomography mentioned a tumor of pancreatic origin as a presumptive diagnosis. At laparotomy, a mass dependent on the body of the pancreas was found. Radical distal pancreatectomy with splenectomy and en bloc partial omentectomy was performed. Results. During the surgery there were no complications and until the sixth month of follow-up, the evolution was adequate and without tumor recurrence. Conclusions. In the presence of an abdominal mass, with pancreatic involvement documented by computed tomography, the diagnosis of solid pseudopapillary neoplasia of the pancreas, or Frantz tumor, should be considered, which must be treated surgically. Frantz tumor is a rare entity that is generally diagnosed incidentally or due to nonspecific symptoms in advanced stages. The diagnosis and management of this neoplasia represents a challenge and surgical resection continues to be the indicated treatment.

Esplenúnculo intrapancreático simulando neoplasia / Intrapancreatic splenunculus simulating neoplasia

Introducción. El esplenúnculo se ha descrito con una incidencia global del 10 al 30 %. Puede ser una entidad de origen congénito o adquirida, frecuentemente está asociada a trauma abdominal o antecedente de esplenectomía por diversas causas. Caso clínico. Mujer en edad media, con antecedente de trauma abdominal y esplenectomía por ruptura traumática, quien 30 años después presenta un cuadro de dolor abdominal. Los estudios imagenológicos identificaron una masa sólida intrapancreática. Resultados. Fue llevada a pancreatectomía distal. Los hallazgos histológicos e inmunohistoquímicos confirmaron que la masa pancreática correspondía a un esplenúnculo intrapancreático adquirido, asociado al evento traumático previo. Conclusión. Los esplenúnculos suelen constituir un "incidentaloma". Los estudios imagenológicos se encuentran limitados, pues la tomografía computarizada, la resonancia nuclear magnética y la ultrasonografía presentan características imagenológicas similares con los tumores pancreáticos hipervascularizados, por lo que se debe practicar el estudio histopatológico durante su valoración. Esta entidad se debe incluir dentro de los diagnósticos diferenciales, con mayor énfasis en aquellos pacientes con historia de trauma abdominal y esplenectomía asociada, un escenario en el que esta lesión puede simular una neoplasia sólida del páncreas, con características malignas.

Introduction. Splenunculus has been described with an overall incidence of 10 to 30%. It can be an entity of congenital or acquired origin, it is frequently associated with abdominal trauma or a history of splenectomy for various reasons. Clinical case. Middle-aged woman, with a history of abdominal trauma and splenectomy due to traumatic rupture, who 30 years later presents with abdominal pain. Imaging studies identified a solid intrapancreatic mass. Results. She was taken to OR for distal pancreatectomy. The histological and immunohistochemical findings confirmed that the pancreatic mass corresponded to an acquired intrapancreatic splenunculus, associated with the previous traumatic event. Conclusion. Splenuncles usually constitute an "incidentaloma". Imaging studies are limited, since computed tomography, magnetic resonance imaging, and ultrasonography present similar imaging characteristics with hypervascularized pancreatic tumors, so histopathological study must be included during their evaluation. This entity should be included in the differential diagnoses, with greater emphasis on those patients with a history of abdominal trauma and associated splenectomy, a scenario in which this lesion can simulate a solid neoplasm of the pancreas, with malignant characteristics.

Hanseníase na atenção básica: saberes e práticas dos profissionais da Estratégia Saúde da Família / Leprosy in primary care: knowledge and practices of professionals in the Family Health Strategy

O objetivo deste estudo é descrever a capacitação de profissionais de saúde na avaliação dermatoneurológica e do grau de incapacidade física em hanseníase, realizada em um posto de Saúde. Trata-se de uma Pesquisa-ação desenvolvida de maio a agosto de 2019 com médicos, enfermeiros e fisioterapeuta da atenção básica. Foi utilizado para coleta de dados questionário autoaplicado, através da plataforma Google Forms, gravação audiovisual e registro em diário de campo durante as oficinas teóricas e práticas. O processo interpretativo deu-se através da análise de conteúdo. Inicialmente, foi realizado o diagnóstico situacional, no qual os profissionais relataram insegurança e deficiência tanto no conhecimento como na habilidade para o atendimento ao paciente com hanseníase. Além disso, não participaram de capacitações acerca do tema. Foram realizadas oficinas para desenvolver competências necessárias. A avaliação das oficinas mostrou uma melhoria do conhecimento e das práticas de cuidado aos usuários durante o estudo. É importante o incentivo às capacitações periódicas dos profissionais de saúde da atenção básica. Além disso, incluir na prática o monitoramento sistemático dos casos novos, busca ativa de casos suspeitos e dos contatos da pessoa com hanseníase. Para que se interrompa a cadeia de transmissão, faz-se necessária a adoção dessas práticas a fim de controlar os casos de hanseníase.

The aim of this study is to describe the training of health professionals in the dermatoneurological assessment and the degree of physical disability in leprosy performed at a health center. This is an action research developed from may to august 2019 with doctors, nurses and physical therapists in primary care. A self-administered questionnaire was used for data collection, through the google forms platform, audiovisual recording and field diary recording during the theoretical and practical workshops. The interpretive process took place through content analysis. Initially, the situational diagnosis was carried out, where professionals reported insecurity and deficiency in both knowledge and ability to care for patients with leprosy. In addition, they did not participate in training on the subject. Workshops were held to develop necessary skills. The evaluation of the workshops showed an improvement in knowledge and care practices for users during the study. It is important to encourage periodic training of primary care health professionals. Include in practice the systematic monitoring of new cases, active search for suspected cases and contacts of the person with leprosy. In order to interrupt the chain of transmission, it is necessary to adopt these practices in order to control leprosy cases.

Necrotizing sialometaplasia: systematic review and meta analyses over the past 46 years

Objectives: The aim of this study was to characterize the main characteristics of this disease in relation to diagnosis, clinical aspects, progression and treatment as well as correlating them with remission time. Material and Methods: A systematic search was performed following the guidelines given by PRISMA and the Joanna Briggs Institute. PubMed, Web of Science and Scopus were the databases used. Results: The final analysis resulted in 108 articles with 173 clinical cases. The longest remission time for signs and symptoms (>7 weeks) was registered among male patients (p = 0.02) and outside the oral cavity; however no significant correlation was observed (p>0.05). A high risk of bias was the most common rating among the articles analyzed (55%); followed by moderate (27%) and low (18%). The lack of standardization in clinical case report descriptions made it difficult to gain a thorough knowledge of the essential characteristics of the NS patho-logical processes. Conclusion: It is recommended that publications follow the standards recommended by the literature; in addition, studies using advanced technologies to better understand NS's pathological path are recommended so as to propose effective treatments for this disease.

Diagnóstico prenatal de clorhidrorrea congénita: reporte de caso / Prenatal diagnosis of congenital chloride diarrhea: A case report

La clorhidrorrea congénita es un trastorno genético infrecuente pero importante caracterizado por una alteración grave del balance hidroelectrolítico como resultado de un defecto en la absorción intestinal de cloruros. Los niños afectados presentan diarrea persistente, deshidratación y malnutrición; el control médico y del desarrollo son complejos. Mejorar la detección prenatal es esencial para facilitar la atención del paciente, las intervenciones tempranas y el asesoramiento genético informado. Sin embargo, a pesar de los avances de la medicina, la naturaleza compleja y la escasa frecuencia de esta entidad, constituyen un desafío para la detección prenatal. En este estudio, se reporta el caso de una embarazada donde los estudios por imágenes de resonancia magnética fetales identificaron en forma efectiva las características típicas de la clorhidrorrea congénita. Se proveen conocimientos sobre las complejidades del diagnóstico y se sugieren caminos para las estrategias de detección temprana de esta enfermedad.

Congenital chloride diarrhea (CCD) is a rare but significant genetic disorder characterized by severe electrolyte imbalances resulting from impaired intestinal chloride absorption. Affected children experience persistent diarrhea, dehydration, and malnutrition, complicating medical and developmental care. The enhancement of prenatal detection is crucial for improved patient management, early interventions, and informed genetic counseling. However, despite advancements in medicine, the complex nature and rarity of CCD make prenatal detection challenging. In this study, we report a fetal case where prenatal magnetic resonance imaging (MRI) effectively identified the distinctive characteristics of CCD, providing insights into the complexities of diagnosis and suggesting avenues for enhanced early detection strategies.

Este artigo se baseia em um estudo feito com o objetivo de analisar indicadores sobre a testagem da sífilis na gestação no Programa de Qualificação das Ações de Vigilância em Saúde (PQAVS) e no Programa Previne Brasil no estado da Paraíba, e também de levantar aspectos do tratamento terapêutico para sífilis gestacional. Trata-se de uma pesquisa descritiva-exploratória, na qual foram sistematizados dados do indicador 11, testes por gestantes, do PQAVS e do indicador de desempenho da Atenção Primária à Saúde (APS), com base na proporção de gestantes que realizaram exames de sífilis e HIV durante o pré-natal em 2020; também foi feita a sistematização do webquestionário direcionado a profissionais da APS (médicos/enfermeiros) e autoaplicado sobre a atuação e tratamento terapêutico para sífilis gestacional. Dos 223 municípios da Paraíba, apenas 12% atingiram a meta do PQAVS e 39% a do Previne Brasil em 2020. Em relação ao webquestionário, houve a participação de 142 profissionais, dos quais 85% realizam o tratamento terapêutico preconizado pelo Ministério da Saúde para a APS. Desse modo, deve ser ressaltada a importância da ampliação da oferta de testes para sífilis, dos insumos para o tratamento adequado e da qualificação dos profissionais e da informação em saúde.

This article is based on a study to analyze indicators on syphilis testing during pregnancy in the PQAVS - Programa de Qualificação das Ações de Vigilância em Saúde (Health Surveillance Actions Qualification Programme) and in the Programa Previne Brasil (Previne Brasil Programme) in the state of Paraíba, Brazil, and also to survey aspects of the therapeutic management for gestational syphilis. It is a descriptive-exploratory research, in which data from indicator 11, tests for pregnant women, from the PQAVS and from the Primary Health Care (PHC) performance indicator, based on the proportion of pregnant women with syphilis and HIV tests during prenatal care in 2020 were systematised; in addition to this systematization, a self-administered webquestionnaire on the performance and therapeutic management for gestational syphilis by professionals (doctors/nurses) from the PHC was also systematised. Taking into account the 223 municipalities in Paraíba, only 12% reached the PQAVS goal and 39% reached the Previne Brasil goal in 2020. Regarding the webquestionnaire, 85% of the 142 professionals who answered it, carry out the therapeutic management recommended by the Ministry of Health for the PHC. Thus, it is fundamental to emphasise the importance of expanding the supply of tests for syphilis, supplies for adequate treatment, and the qualification of health professionals and information.
