Telerehabilitación respiratoria en fibrosis quística: experiencia de pacientes, padres y profesionales durante la pandemia de COVID-19. Estudio cualitativo

Introducción: la rehabilitación respiratoria (RR) se recomienda en pacientes con fibrosis quística (FQ). Durante la pandemia de COVID-19 los programas de RR debieron cerrarse o migrar a modalidades de telerehabilitación, imponiendo nuevos desafíos a pacientes y equipos de salud. El objetivo de este estudio fue explorar las percepciones de pacientes, padres y profesionales sobre la transición a la telerehabilitación respiratoria durante la pandemia de COVID-19. Método: estudio cualitativo. Se consideraron pacientes con FQ mayores de 8 años. También a padres y equipos de salud. El tamaño muestral se determinó mediante saturación teórica. Se realizaron entrevistas semiestructuradas y grupos focales vía Zoom. El análisis de datos se realizó mediante los métodos de codificación abierta y axial. El análisis se realizó utilizando el software Atlas. Ti 7.5.7. Resultados: se incluyó a 4 pacientes adultos, 1 pediátrico y 2 padres, además de 4 profesionales de equipos de salud. Existió una percepción general positiva respecto a la RR y la telerehabilitación. Entre las barreras destacó la falta de equipamiento para la telerehabilitación en domicilio y la organización diaria de los pacientes. Entre los facilitadores destacó la disponibilidad de equipos y redes que permitieran la conectividad y el apoyo familiar. Existió una valoración positiva hacia la continuidad de la telerehabilitación en la etapa post pandémica. Conclusiones: la telerehabilitación fue percibida como una alternativa viable y efectiva, sin embargo, aspectos de la conectividad, disponibilidad de equipamiento y la rutina diaria de los pacientes debe ser considerada a la hora de implementar modalidades telemáticas de atención.

Introduction: Pulmonary rehabilitation (PR) is recommended in patients with Cystic Fibrosis (CF). During the COVID-19 pandemic, PR programs had to migrate to telerehabilitation modalities, imposing new challenges for patients and health teams. The objective of this study was to explore the perceptions of patients, parents, and professionals regarding the transition to respiratory telerehabilitation experienced during the COVID-19 pandemic. Method: Qualitative study. Parents and health teams were included in the case of patients with CF over eight years old. Theoretical saturation determined the sample size. Semi-structured interviews and focus groups were conducted using the Zoom platform. Data analysis was carried out using open and axial coding methods. The analysis was performed using Atlas Ti software 7.5.7. Results: Four adult patients, one pediatric patient, two parents, and four health team professionals entered the study. There was a positive perception regarding PR and telerehabilitation. Among the barriers, the lack of equipment for telerehabilitation at home and the daily organization of patients stood out. Among the facilitators, the availability of equipment and networks that allowed connectivity and family support stood out. Patients rated the continuity of telerehabilitation in the post-pandemic stage positively. Conclusions: Telerehabilitation was perceived as a viable and effective alternative; however, aspects related to connectivity, availability of equipment, and the daily routine of patients must be considered when implementing telematics care modalities.

Lesión pancreática que esconde una transformación quística acinar

Objetivo: La transformación quística acinar del páncreas es una patología poco frecuente y que afecta en su mayoría a mujeres de mediana edad. Material y Métodos: Presentamos el caso de dicha patología en un varón joven que debutó con dolor en hipocondrio izquierdo y en la pruebas de imagen se evidenció una lesión quística en cola pancreática de 50x45mm, con calcificaciones lineales. Se realizó pancreatectomía distal. Resultados: El diagnóstico anatomopatológico informó de transformación quística acinar. Discusión: Dada la dificultad de un diagnóstico preoperatorio, es frecuente someter al paciente a una intervención quirúrgica con una elevada morbilidad, a pesar de tratarse de una lesión benigna, ya que se siguen las indicaciones quirúrgicas para otras patologías quísticas pancreáticas. La presencia de mutaciones y el hecho de que algunos de ellos también presentan cambios epiteliales mucinosos, justificaría el debatir la posibilidad de mantener a estos pacientes bajo vigilancia a largo plazo.

Objective: Acinar cystic transformation of the pancreas is a rare pathology that affects mostly middle-aged women. Material and Methods: We present a case of this pathology in a young man who presented with pain in the left hypochondrium and imaging tests revealed a cystic lesion in the pancreatic tail measuring 50x45mm, with linear calcifications. Distal pancreatectomy was performed. Results: The anatomopatho-logical diagnosis was acinar cystic transformation. Discussion: given the difficulty of a preoperative diagnosis, the patient is often subjected to surgery with high morbidity, despite being a benign lesion, as surgical indications for other pancreatic cystic pathologies are followed. The presence of mutations and the fact that some of them also present mucinous epithelial changes would justify discussing the possibility of keeping these patients under long-term surveillance.

Linfangioma Quístico del Páncreas. Un Tumor poco Frecuente / Pancreas Cystic Lymphangioma. A Rare Tumor

El linfangioma quístico del páncreas (LQP), es un tumor extremadamente raro y representa solo el 1% de los linfangiomas abdominales. El objetivo de este manuscrito fue reportar un caso de LQP intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Mujer de 67 años, con LQP operada en Clínica RedSalud Mayor Temuco en septiembre de 2023. Se verificó un tumor sólido-quístico de 16 cm de diámetro mayor, adherido al páncreas a nivel del cuerpo de la glándula, de 867 gramos de peso, con líquido amarillento en su interior; la que fue extirpada completamente. Después del estudio histológico, se realizaron tinciones inmunohistoquímicas complementarias para CD31, D2-40 y calretina. La paciente tuvo un curso postoperatorio sin incidentes, siendo dado de alta al tercer día postoperatorio. En el control alejado, se encontraba en buenas condiciones generales. El LQP es un tumor muy poco frecuente. Las características clínicas e imágenes de este tipo de lesiones son inespecíficas. Debe considerarse en el diagnóstico diferencial de las lesiones quísticas pancreáticas. La resección quirúrgica completa con márgenes libres es el tratamiento de elección; y el pronóstico del LQP es favorable si se reseca por completo.

SUMMARY: Pancreas cystic lymphangioma (PCL) are extremely rare, accounting for only 1% of abdominal lymphangiomas. The aim of this study was to report a rare case of PCL, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. 67-year-woman patient with PCL who underwent surgery at Clínica RedSalud Mayor Temuco in September 2023. In this case, a solid-cystic tumor with a major diameter of 16 cm was identified, adhering to the pancreas at the level of the body of the gland, weighing 867 grams and containing yellowish fluid in its interior. The tumor was completely excised. Subsequent to histological examination, additional immunohistochemical staining was performed for CD31, D2-40, and calretinin. The patient experienced an uneventful postoperative course and was discharged on the third postoperative day. During the follow-up, the patient remains in good general condition. LQP is a very rare tumor. Clinical features and images of this type of lesions are nonspecific. It should be considered in the differential diagnosis of pancreatic cystic lesions. Complete surgical resection with free margins is the treatment of choice; and the prognosis of LQP is favorable if it is completely resected.

Periradicular and Peri-Implant Lesions Associated with Apical Impact of Osseointegrated Implants in Tooth Roots: Clinical Case Reports

This clinical case report aims to describe the development of periradicular and perimplant cystic lesions resulted from the intimate contact of the apical region of osseointegrated implants of dental roots, and discuss the reasons fo r failure of the guided bone regeneration procedure associated with platelet rich fibrin and leukocytes, this process was used to the treatment of the first case. Case Reports. Three cases were reported, two cases described the close contact between the tooth roots and the osseointegrated implants and another with a distance of 1.08 mm. All cases realized a radiographic, and they had not periapical lesions before contact with the apical region of the osseointegrated implants on the roots of the teeth. In the case with the largest cystic extension, the procedure was: removal of the osseointegrated implant with apicectomy of the neighboring teeth, excisional biopsy of the lesion, and grafting using the technique of guided bone regeneration associated with L-PRF. All three cases, endodontic treatment was performed on the neighboring teeth within 2 years of survival of the osseointegrated implants in order to reverse the existing lesion. Results. The diagnostic hypothesis of the three cases was periradicular and peri-implant lesion, arising from a contact of the apical region of the osseointegrated implant with the adja cent tooth. The distance of 1.08 mm between the apices did not ensure normality of the periradicular and peri-implant tissues. The intimate contact caused lesions of different extents and root fractures. Conclusion. Premature contact of the osseointegrated implant with the root region of the neighboring tooth may lead to the development of periradicular and peri-implant lesions, suggesting that it is not possible to control this infectious process with endodontic treatment of the injured tooth.

Este reporte de caso clínico tuvo como objetivo describir el desarrollo de lesiones quísticas perirradiculares y periimplantarias resultantes del contacto íntimo de la región apical de implantes osteointegrados de raíces dentales, y además discutir las razones del fracaso del procedimiento de regeneración ósea guiada asociado a fibrina rica en plaquetas y leucocitos. Este proceso se utilizó para el tratamiento del primer caso. Se reportaron tres casos, en dos casos se describieron el estrecho contacto entre las raíces de los dientes y los implantes osteointegrados y en el otro se determinó una distancia de 1,08 mm. En los tres casos se realizó una radiografía y se determinó que no existían lesiones periapicales, antes del contacto con la región apical de los implantes osteointegrados, en las raíces de los dientes. En el caso de mayor extensión quística, el procedimiento fue: extracción del implante osteointegrado con apicectomía de los dientes vecinos, biopsia excisional de la lesión e injerto mediante la técnica de regeneración ósea guiada asociada a L-PRF. En los tres casos, el tratamiento de endodoncia se realizó en los dientes vecinos dentro de los 2 años de supervivencia de los implantes osteointegrados para revertir la lesión existente. La hipótesis diagnóstica de los tres casos fue lesión perirradicular y periimplantaria, originada por un contacto de la región apical del implante osteointegrado con el diente adyacente. La distancia de 1,08 mm entre los ápices no aseguraba la normalidad de los tejidos perirradiculares y periimplantarios. El contacto íntimo provocó lesiones de diferente extensión y fracturas radiculares. El contacto prematuro del implante osteointegrado con la región radicular del diente vecino puede conducir al desarrollo de lesiones perirradiculares y periimplantarias, lo que sugiere que no es posible controlar este proceso infeccioso con tratamiento endodóntico del diente lesionado.

Utilidad diagnóstica del CD117 en un inusual carcinoma adenoide quístico del labio superior / Diagnostic utility of CD117 in an unusual adenoid cystic carcinoma of the upper lip / Utilidade diagnóstica do CD117 num carcinoma adenoide cístico invulgar do lábio superior

RESUMEN El carcinoma adenoide quístico (CAQ) es una neoplasia maligna de glándula salival, de evolución lenta pero de agresivo comportamiento, que se presenta frecuentemente en el paladar; sin embargo, en el labio superior, donde suelen encontrarse más neoplasias benignas, su presencia es escasamente relatada. Se expone un relato de una mujer de 63 años, derivada por presentar un nódulo en el labio superior derecho, de aspecto benigno, consistencia firme, circunscrito, móvil, doloroso a la palpación, sin tiempo de evolución determinado y cuyo estudio histopatológico exhibió una proliferación de células anguladas e hipercromáticas de escaso citoplasma, organizadas en patrón cribiforme y predominantemente tubular. Se realiza un estudio inmunohistoquímico, el cual mostró positividad para SMA, p63 y CD117 con un Ki-67 del 10 % aproximadamente. Estos resultados confirman diagnóstico de CAQ con patrón tubular, destacando el rol del CD117 para el diagnóstico diferencial con adenocarcinoma polimorfo. Se deriva a la paciente para tratamiento quirúrgico y radioterapia, y luego de un año de seguimiento mantiene un buen comportamiento clínico.

ABSTRACT Adenoid cystic carcinoma (ACCC) is a malignant neoplasm of the salivary gland, of slow evolution but aggressive behavior, which frequently occurs in the palate; however, in the upper lip, where more benign neoplasms are usually found, its presence is scarcely reported. We report the case of a 63-year-old woman, referred for presenting a nodule in the right upper lip, with benign appearance, firm consistency, circumscribed, mobile, painful to palpation, with no determined time of evolution and whose histopathological study showed a proliferation of angular and hyperchromatic cells with scarce cytoplasm, organized in a cribriform pattern and predominantly tubular. An immunohistochemical study was performed, which showed positivity for SMA, p63 and CD117 with a Ki-67 of approximately 10%. These results confirm the diagnosis of CAC with tubular pattern, highlighting the role of CD117 for the differential diagnosis with polymorphous adenocarcinoma. The patient was referred for surgical treatment and radiotherapy, and after one year of follow-up she maintained a good clinical behavior.

RESUMO O carcinoma adenoide cístico (CACC) é uma neoplasia maligna da glândula salivar, de evolução lenta, mas de comportamento agressivo, que ocorre frequentemente no palato; no entanto, a sua presença é raramente relatada no lábio superior, onde normalmente se encontram neoplasias mais benignas. Relatamos o caso de uma mulher de 63 anos que foi encaminhada por apresentar um nódulo benigno no lábio superior direito, de aspeto firme, circunscrito, móvel, doloroso à palpação, sem tempo de evolução definido. O exame histopatológico revelou uma proliferação de células angulosas e hipercromáticas com citoplasma escasso, organizadas em padrão cribriforme e predominantemente tubulares. Foi efetuado um estudo imuno-histoquímico que mostrou positividade para SMA, p63 e CD117 com um Ki-67 de aproximadamente 10 %. Estes resultados confirmam o diagnóstico de CAC com padrão tubular, realçando o papel do CD117 no diagnóstico diferencial com adenocarcinoma polimorfo. A paciente foi encaminhada para tratamento cirúrgico e radioterapia e, após um ano de seguimento, manteve bom comportamento clínico.

Malformación linfática quística gigante del hígado: dos casos pediátricos con diferente abordaje quirúrgico / Giant cystic lymphatic malformation of the liver: two pediatric cases with different surgical approach

Introducción. Las malformaciones linfáticas quísticas, también llamadas linfangiomas quísticos, aparecen muy raramente de forma aislada en el hígado. Casos clínicos. Se presentan dos pacientes femeninas de edad preescolar con marcada hepatomegalia, dependiente de lesiones quísticas multitabicadas, secundarias a malformación linfática quística gigante del hígado, que fueron tratadas en el Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Resultados. En ambos casos el diagnóstico se apoyó en los estudios de imágenes, la laparoscopia y el análisis histopatológico. En un caso el tratamiento fue la hepatectomía derecha, mientras que en el otro se empleó la escleroterapia, ambas con evolución favorable. Conclusión. A pesar de su rareza, este diagnóstico no debe obviarse ante un paciente pediátrico con lesiones hepáticas quísticas. El tratamiento de elección es la resección quirúrgica, pero su indicación y envergadura debe valorarse de forma individualizada

Introduction. Cystic lymphatic malformations, also called cystic lymphangiomas, are very rarely found in the liver. Clinical cases. Two pediatric female preschool-age patients. presented with hepatomegaly due to multi-septated cystic lesions of the liver, who received treatment at Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Results. We report two pediatric cases with giant cystic lymphatic malformation of the liver. In both cases, the diagnosis were based on imaging, laparoscopy and pathology. In one case the treatment was right hepatectomy, whereas in the other, sclerotherapy was performed, both with a favorable outcome. Conclusion. Despite its rarity, this diagnosis should be considered in pediatric patients with hepatic cystic lesions. The recommended treatment is surgical resection, but its indication and extent should be assessed individually for each patient.

Coincidental finding of Sertoli-Leydig Cell Tumor in a postmenopausal woman with mild hyperandrogenism, ovarian teratoma, and pelvic organ prolapse: A case report

@#A Sertoli-Leydig cell tumor (SLCT) is an extremely rare type of sex cord stromal tumor of the ovary, which mainly secretes testosterone, thus manifestations of hyperandrogenism commonly appear. This paper shall discuss a case of a postmenopausal woman who presented with pelvic organ prolapse, large left ovarian cyst and mild signs of hyperandrogenism. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, which on microscopic examination of the specimens, revealed a Mature cystic teratoma on the left ovary and an incidental finding of a well-differentiated SLCT, on the grossly normal-looking ovary. This histopathologic diagnosis of SLCT explained the patient’s hyperandrogenic characteristics. Authors likewise discussed the proper management of SLCT, including immunostaining and need for adjuvant chemotherapy.

A clinicopathological analysis of cervical carcinoma with basaloid features / 实用医学杂志

Objective To investigate the clinical and pathological features of adenoid basal cell carcinoma(ABC),adenoid cystic carcinoma(ACC),and basaloid squamous cell carcinoma(BSCC)with basaloid charac-teristics and improve the diagnostic and differential diagnostic ability of clinicians and pathologists for these lesions.Methods A retrospective study was conducted on the clinical and pathological data of 4 cases of ABC,1 case of ACC,and 3 cases of BSCC diagnosed and treated at Shenzhen Maternal and Child Health Hospital,Southern Medical University from April 2018 to December 2022.Pathological slides were reviewed and relevant literature was analyzed and summarized.Results All three types of tumors were common in postmenopausal women and were associated with high-risk HPV infection.ABC was a low-grade cancer and patients were often clinically asymp-tomatic.It was usually detected incidentally during cervical screening due to cytological abnormalities,or after cervical cone biopsy or hysterectomy for HSIL.It presented as superficial cervical infiltration and clinical staging was often early.ACC and BSCC were intermediate to high-grade cancers and they often presented with postmenopausal vaginal bleeding.A visible mass was observed on the cervix.The clinical staging was intermediate to advanced.The three types of lesions could coexist.Careful observation of the morphological characteristics and immunohistochemical staining could help with differential diagnosis.None of the 8 patients experienced recurrence or metastasis during follow-up.Conclusion Cervical ABC,ACC and BSCC are rare and they originate from reserve cells.They share the similarities in clinical and pathological morphology,but differ in treatment and prognosis.So,accurate differen-tiation among them has important clinical significance.

Impact of COVID-19 social distancing recommendations on pulmonary function, nutritional status, and morbidity in patients with cystic fibrosis / Impacto das recomendações de distanciamento social por COVID-19 sobre a função pulmonar, estado nutricional e morbidade em pacientes com fibrose cística

ABSTRACT Objective: To evaluate the impact of COVID-19 social distancing recommendations on nutritional status, pulmonary function, and morbidity in patients with cystic fibrosis (CF). Methods: A retrospective cohort study including patients older than six years with a diagnosis of CF was performed. Demographic and clinical data, anthropometric measurements, pulmonary function, days of antibiotic use, and length of hospital stay were recorded. Variables were recorded at three time points relative to the baseline for implementation of social distancing measures: T-1 (14 months before implementation), T0 (baseline), and T1 (14 months after implementation). Delta (Δ) was calculated for each period: Δ1 (pre-pandemic T0-T-1) and Δ2 (pandemic T1-T0). Results: The study included 25 patients, with a mean age of 11.7±4.3 years. The mean forced expiratory volume in the first second (FEV1) was 85.6±23.6%, and body mass index (BMI) was 17.5±3.0 kg/m2. When comparing the two periods (Δ1 and Δ2), there was a significant increase in the FEV1/forced vital capacity (FVC) ratio (p=0.013) and in the forced expiratory flow between 25 and 75% of vital capacity (FEF25-75%) (p=0.037) in the pandemic period. There was also a significant reduction (p=0.005) in the use of antibiotics in the pandemic period compared with the pre-pandemic period. The Δ1 and Δ2 values did not differ significantly for BMI, FEV1, or length of hospital stay. Conclusions: COVID-19 social distancing recommendations had a positive impact (decrease) on morbidity (use of antibiotics) and small airway obstruction (FEF25-75%) in patients with CF.

RESUMO Objetivo: Avaliar o impacto das recomendações de medidas de distanciamento social por COVID-19 sobre estado nutricional, função pulmonar e morbidade em pacientes com fibrose cística (FC). Métodos: Estudo de coorte, retrospectivo, que incluiu pacientes com diagnóstico de FC e idade superior a seis anos. Foram registrados os dados demográficos, antropométricos, clínicos, de função pulmonar e o total de dias de uso de antibiótico e de hospitalizações. As variáveis foram registradas em três momentos relativos ao início das recomendações de distanciamento social: T-1 (14 meses antes), T0 (início das recomendações) e T1 (14 meses depois). Foram calculados deltas (Δ) para cada um dos períodos: Δ1 (pré-pandemia T0-T-1) e Δ2 (pandemia T1-T0). Resultados: Vinte e cinco pacientes, com média de idade de 11,7±4,3 anos, sendo 76% homozigotos para Δf508 e 28% colonizados por Pseudomonas aeruginosa, foram incluídos. A média do volume expiratório forçado no primeiro segundo (VEF1) foi de 85,6±23,6 (% do previsto) e o índice de massa corporal (IMC) foi de 17,5±3,0 kg/m2. Ao compararmos os períodos (Δ1 e Δ2), houve aumento significativo do VEF1/CVF (p=0,013) e do FEF25-75% (p=0,037) no período das recomendações de distanciamento. Também se observou redução significativa (p=0,005) do uso de antibióticos no período da pandemia em comparação ao período anterior a ela. Não houve diferenças significativas nos deltas para o IMC, VEF1 e dias de hospitalização. Conclusões: As recomendações de distanciamento social por COVID-19 tiveram impacto positivo (redução) sobre a morbidade (uso de antibióticos) e a obstrução de vias aéreas de menor calibre (FEF25-75%) em pacientes com FC.

Establishment and validation of a predictive model for the progression of pancreatic cystic lesions based on clinical and CT radiological features / 中华胰腺病杂志

Objective:To construct a machine-learning model for predicting the progression of pancreatic cystic lesions (PCLs) based on clinical and CT features, and to evaluate its predictive performance in internal/external testing cohorts.Methods:Baseline clinical and radiological data of 200 PCLs in 177 patients undergoing abdominal thin slice enhanced CT examination at Peking Union Medical College Hospital from July 2014 to December 2022 were retrospectively collected. PCLs were divided into progressive and non-progressive groups according to whether the signs indicated for surgery by the guidelines of the European study group on PCLs were present during three-year follow-up. 200 PCLs were randomly divided into training (150 PCLs) and internal testing cohorts (50 PCLs) at the ratio of 1∶3. 15 PCLs in 14 patients at Jinling Affiliated Hospital of Medical School of Nanjing University from October 2011 to May 2020 were enrolled as external testing cohort. The clinical and CT radiological features were recorded. Multiple feature selection methods and machine-learning models were implemented and combined to identify the optimal machine-learning model based on the 10-fold cross-validation method. Receiver operating characteristics (ROC) curve was drawn and area under curve (AUC) was calculated. The model with the highest AUC was determined as the optimal model. The optimal model's predictive performance was evaluated on testing cohort by calculating AUC, sensitivity, specificity and accuracy. Permutation importance was used to assess the importance of optimal model features. Calibration curves of the optimal model were established to evaluate the model's clinical applicability by Hosmer-Lemeshow test.Results:In training and internal testing cohorts, the progressive and non-progressive groups were significantly different on history of pancreatitis, lesions size, main pancreatic duct diameter and dilation, thick cyst wall, presence of septation and thick septation (all P value <0.05) In internal testing cohort, the two groups were significantly different on gender, lesion calcification and pancreatic atrophy (all P value <0.05). In external testing cohort, the two groups were significantly different on lesions size and pancreatic duct dilation (both P<0.05). The support vector machine (SVM) model based on five features selected by F test (lesion size, thick cyst wall, history of pancreatitis, main pancreatic duct diameter and dilation) achieved the highest AUC of 0.899 during cross-validation. SVM model for predicting the progression of PCLs demonstrated an AUC of 0.909, sensitivity of 82.4%, specificity of 72.7%, and accuracy of 76.0% in the internal testing cohort, and 0.944, 100%, 77.8%, and 86.7% in the external testing cohort. Calibration curved showed that the predicted probability by the model was comparable to the real progression of PCLs. Hosmer-Lemeshow goodness-of-fit test affirmed the model's consistency with actual PCLs progression in testing cohorts. Conclusions:The SVM model based on clinical and CT features can help doctors predict the PCLs progression within three-year follow-up, thus achieving efficient patient management and rational allocation of medical resource.

Small lesion detection in ultrasound images of hepatic cystic echinococcosis based on improved YOLOv7 / 中国医学物理学杂志

Objective To propose a novel algorithm model based on YOLOv7 for detecting small lesions in ultrasound images of hepatic cystic echinococcosis.Methods The original feature extraction backbone was replaced with a lightweight feature extraction backbone network GhostNet for reducing the quantity of model parameters.To address the problem of low detection accuracy when the evaluation index CIoU of YOLOv7 was used as a loss function,ECIoU was substituting for CIoU,which further improved the model detection accuracy.Results The model was trained on a self-built dataset of small lesion ultrasound images of hepatic cystic echinococcosis.The results showed that the improved model had a size of 59.4 G and a detection accuracy of 88.1%for mAP@0.5,outperforming the original model and surpassing other mainstream detection methods.Conclusion The proposed model can detect and classify the location and category of lesions in ultrasound images of hepatic cystic echinococcosis more efficiently.

Preliminary Study on Prognostic Factors of New-onset Diabetes Mellitus After Distal Pancreatectomy for Pancreatic Cystic Tumor / 中国微创外科杂志

Objective To explore the prognostic factors of new-onset diabetes mellitus(NODM)in patients with pancreatic cystic tumor after distal pancreatectomy(DP).Methods Between January 2010 and December 2019,92 patients with cystic pancreatic tumors in our hospital underwent laparoscopic DP.According to the inclusion and exclusion criteria,a total of 74 cases were included and divided into NODM group or normal glucose metabolism group based on whether postoperative NODM occurred.A univariate analysis was used to evaluate the prognostic factors of laparoscopic DP for pancreatic cystic tumors.P<0.05 was considered statistically significant,OR>4 was considered as a potential prognostic factor of clinical significance for NODM.Results NODM was diagnosed in26 cases(35.1%),with a median diagnosis time of 9 months(range,3-56 months)after surgery.Univariate analysis showed that transecting pancreas in the neck(OR = 11.000,P = 0.000),BMI≥25.0(OR = 4.333,P = 0.007),and family history of diabetes mellitus(OR =5.000,P =0.004)were prognostic factors of postoperative NODM.Conclusions When performing DP for pancreatic cystic tumors,it is advisable to preserve as much pancreatic tissue as possible and avoid cutting off the pancreas in the neck.Precise postoperative strategy of glucose metabolism surveillance for patients with BMI≥25.0 and family history of diabetes mellitus should be promoted.

Ruptured urachal mucinous cystic tumor of low malignant potential: A case report and review of literature

@#Neoplasms of the urachus are uncommon, consisting of only 0.17% of all bladder malignancy. Mucinous cystic tumor of low malignant potential (MCLTMP) is a rare subtype with only 26 cases reported in the literature as of 2023. These tumors may present in a variety of ways such as hematuria, mucusuria, lower abdominal pain and irritative lower urinary tract symptoms. This is a case of 43-year-old female presenting at the emergency room for abdominal pain initially managed as a case of ovarian new growth in complication who underwent exploratory laparotomy, adhesiolysis, bilateral salpingectomy, partial cystectomy enbloc removal of urachal with anterior peritonectomy and excision of umbilicus. Histopathologic examination revealed mucinous cystic tumor of low malignant potential (MCLTMP) of the urachus. It is important to consider the possibility of a ruptured urachal cyst in a female patient who presents with hypogastric abdominal pain. A transabdominal and transvaginal ultrasound may lead to an incorrect diagnosis. In such cases where the patient presented with an acute abdomen, knowledge that a ruptured urachal cyst maybe a differential for such masses would lead to a strategic laparotomy incision aimed at a possible en-bloc removal of the umbilicus while maintaining the connections of the possible urachal mass to the urinary bladder.

A ten-year review of congenital pulmonary airway malformation cases in a pediatric tertiary hospital

Objective@#A retrospective study of the demographic, clinical and diagnostic profile, intervention and outcomes of children with Congenital Pulmonary Airway Malformation (CPAM) in Philippine Children’s Medical Center (PCMC) from January 2011 to December 2021 was presented.@*Methodology@#Medical charts of identified patients were reviewed. Data obtained included demographic profile, clinical history, diagnostic procedures, intervention, and outcomes. The findings were analyzed and correlated with the synthesized findings from relevant studies about CPAM.@*Results@#Twenty-three cases (n=23) were included in the study. Most of the patients were diagnosed at 1 to 11 months of age, accounting for 43.48% while there is a minimal disparity in terms of gender distribution. Seventy-five percent of neonates presented with respiratory distress while recurrent pneumonia occurred more frequently beyond the neonatal period. Four patients at 17.39% had incidental findings of CPAM on prenatal ultrasound. All cases were confirmed using a Chest CT scan and only six patients at 26.09% had Chest X-ray results consistent with CPAM. Eight cases were confirmed using biopsy wherein results were mainly Type I seen in 87.5% of cases. Lobectomy is the procedure of choice with 92.86% success rate. Overall, patients who underwent surgical intervention had a low complication rate at 6.25%. @*Conclusion@#CPAM is most common in patients aged 1 to 11 months and has no gender predilection. Neonates often present with respiratory distress while recurrent pneumonia is the most common clinical manifestation beyond neonatal period. CPAM can be detected using ultrasound prenatally and CT scan can confirm CPAM postnatally. Surgical intervention particularly lobectomy is the preferred option over conservative management which showed a favorable outcome. CPAM has an overall good prognosis. Findings of this research may guide clinicians in the diagnosis and management of CPAM in the Philippines.

Effect of Baihe Yuzi Prescription on CFTR， AQP， and ZIP Ion Channels and Oxidative Stress in Epididymis of Oligoasthenozoospermia Rats / 中国实验方剂学杂志

ObjectiveTo observe the effects of Baihe Yuzi prescription （BYP） on the cystic fibrosis transmembrane conductance regulator （CFTR）， aquaporin （AQP）， zinc/iron-regulated transporter-like protein （ZIP） and local oxidative stress in epididymis of oligoasthenozoospermia （OAS） rats， and to explore the mechanism of its intervention in OAS. MethodAfter 35 rats were acclimatized for 1 week， 7 rats were randomly selected as the normal group， and the remaining 28 rats were given tripterygium glycosides （TG） 30 mg·kg-1. After 4 weeks of modeling， they were randomly divided into 4 groups： model group， BYP low-dose group （LBYP）， BYP high-dose group （HBYP） and levocarnitine group， with 7 rats in each group. The rats in the normal group and model group were given normal saline at the same dosage. The levocarnitine group rats were given L-carnitine oral liquid （100 mg·kg-1） by gavage. The LBYP group rats were given BYP 6.3 g·kg-1， and the HBYP group rats were given BYP 12.6 g·kg-1 by gavage once a day for consecutive 4 weeks. After the end of the intervention， sperm count and motility of all rats were detected， the histopathological structure of epididymis was observed by hematoxylin-eosin （HE） staining， and the expressions of CFTR， AQP9， AQP3， ZIP8， ZIP12 and other proteins were detected by Western blot. The contents of α-glycosidase （α-GC）， sialic acid （SA）， carnitine， superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px） and malondialdehyde （MDA） were detected by enzyme-linked immunosorbent assay （ELISA）. Total zinc content was measured using an inductively coupled plasma mass spectrometer. Free zinc ion content was detected by zinc ion probes. ResultCompared with those in the normal group， the sperm count and motility of rats were decreased and the epididymal structure was disordered in the model group. The contents of α-GC and carnitine were decreased in epididymis （P<0.05）. MDA levels were increased， while SOD， GSH-Px and zinc levels were decreased （P<0.05）. The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were down-regulated， and AQP3 expression was up-regulated.

Association of TP53 germline variant and choledochal cyst among clinically diagnosed Filipino pediatric patients

@#Background and Objective. Choledochal cysts (CC) are rare congenital, cystic dilations of the biliary tree occurring predominantly in Asian populations and in females. Patients are usually children presenting with any of the following: abdominal pain, palpable abdominal mass, and jaundice. Its congenital nature hints at a potential genetic cause. A possible causal gene is TP53, a tumor suppressor with a germline variant called rs201753350 (c.91G>A) that changed from a G allele to an A allele, decreasing the cell proliferation suppressing activity of its functional protein. Currently, there is no information on the TP53 rs201753350 germline variant available for the Filipino population. This study determined the prevalence of rs201753350 and the association between the functional G allele, the rs201753350 germline variant A allele, and the occurrence of CCs in Filipino pediatric patients in a tertiary government hospital. Methods. Genomic DNA was extracted from blood samples of pediatric patients clinically diagnosed with CC. Controls were DNA samples collected from a previous study. The samples underwent PCR, electrophoresis, and sequencing. Results. A total of 109 participants (22 cases and 87 controls) were included in the study. The A allele (22.94%) occurs at a lower frequency than the G allele (77.06%) among both cases and controls. More individuals have a homozygous G/G genotype (54.13%) than a heterozygous A/G genotype (45.87%) while the homozygous A/A genotype was not observed. The estimated risk of choledochal cyst occurrence is significantly lower in individuals with the A allele (PR: 0.08, 95% CI: 0.01 – 0.55) and the A/G genotype (PR: 0.06, 95% CI: 0.01 – 0.40). Conclusion. There is no significant evidence to suggest an association between the TP53 rs201753350 germline variant and the occurrence of choledochal cysts in Filipinos. It is recommended that other mutations within and beyond the TP53 gene be investigated for possible associations with choledochal cyst occurrence.

Exploration of CT imaging features of cystic pulmonary nodules and establishment of a prediction model for benign and malignant pulmonary nodules / 中国胸心血管外科临床杂志

@#Objective To explore the CT imaging features and independent risk factors for cystic pulmonary nodules and establish a malignant probability prediction model. Methods The patients with cystic pulmonary nodules admitted to the Department of Thoracic Surgery of the First People's Hospital of Neijiang from January 2017 to February 2022 were retrospectively enrolled. They were divided into a malignant group and a benign group according to the pathological results. The clinical data and preoperative chest CT imaging features of the two groups were collected, and the independent risk factors for malignant cystic pulmonary nodules were screened out by logistic regression analysis, so as to establish a prediction model for benign and malignant cystic pulmonary nodules. Results A total of 107 patients were enrolled. There were 76 patients in the malignant group, including 36 males and 40 females, with an average age of 59.65±11.74 years. There were 31 patients in the benign group, including 16 males and 15 females, with an average age of 58.96±13.91 years. Multivariate logistic analysis showed that the special CT imaging features such as cystic wall nodules [OR=3.538, 95%CI (1.231, 10.164), P=0.019], short burrs [OR=4.106, 95%CI (1.454, 11.598), P=0.008], cystic wall morphology [OR=6.978, 95%CI (2.374, 20.505), P<0.001], and the number of cysts [OR=4.179, 95%CI (1.438, 12.146), P=0.009] were independent risk factors for cystic lung cancer. A prediction model was established: P=ex/(1+ex), X=–2.453+1.264×cystic wall nodules+1.412×short burrs+1.943×cystic wall morphology+1.430×the number of cysts. The area under the receiver operating charateristic curve was 0.830, the sensitivity was 82.9%, and the specificity was 74.2%. Conclusion Cystic wall nodules, short burrs, cystic wall morphology, and the number of cysts are the independent risk factors for cystic lung cancer, and the established prediction model can be used as a screening method for cystic pulmonary nodules.

EZH2 immunoexpression in pleomorphic adenoma and adenoid cystic carcinoma and clinicopathological features

Abstract The aim of this study was to evaluate the expression of the EZH2 protein and describe the clinical and microscopic characteristics of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA). The study included 16 ACC cases and 12 PA. All ACC and PA cases were positive for EZH2 and the ACC samples showed significantly higher EZH2 expression. The clinical and microscopic covariates were described in relation to EZH2 staining in ACC samples. The highest mean values of EZH2 were observed in cases with local metastasis, recurrence, perineural invasion, and predominantly cribriform growth pattern without solid areas. EZH2 is a potential marker of malignancy.

Alternativa terapéutica para mejorar la calidad de vida en pacientes con fibrosis quística y discinesia ciliar primaria / Therapeutic alternative to improve quality of life in patients with cystic fibrosis and primary ciliary dyskinesia

Objective: To evaluate the clinical response of patients with cystic fibrosis and primary ciliary dyskinesia after endoscopic sinus surgery at the Dr. Robert Reid Cabral Children's Hospital from September 2021 to February 2022. Methods: An ambispective, cross-sectional, observational case series study was conducted, where the study population was made up of patients with cystic fibrosis and primary ciliary dyskinesia at the Dr. Robert Reid Cabral children's hospital during the study period. Inclusion criteria: Patients older than 6 years with a confirmed diagnosis of cystic fibrosis and primary ciliary dyskinesia (Genetic test with 2 homozygous mutations, positives electrolytes in sweat), severe respiratory symptoms of CRS that did not improve with conventional treatment and underwent endoscopic surgery for sinuses. Results: Of a total of 41 patients, only 10 met the inclusion criteria, the most prevalent age range was 14 to 18 years. Both CF and PCD patients decreased the frequency of CRS symptoms. After ENC, there were discrete changes in lung function, and only patients with severe to moderate disease increased % of FEV1. Most of the patients did not require admission after surgery. The most common germ found in nasopharyngeal and sputum cultures in preoperative patients was Pseudomonas aeruginosa in 86%; after ESS there was a significant increase in MRSA colonization in both CF and PCD patients. More than 50% of postoperative patients improved their quality of life, so endoscopic sinus surgery is effective in this population in the treatment of chronic rhinosinusitis.

Objetivo: Evaluar la respuesta clínica de los pacientes con fibrosis quística y discinesia ciliar primaria posterior a la cirugía endoscópica de senos paranasales en el Hospital Infantil Dr. Robert Reid Cabral en el período septiembre 2021 a febrero 2022. Métodos: Se realizó un estudio observacional tipo serie de casos, de corte transversal y ambispectivo, donde la población estudiada estuvo conformada por los pacientes con fibrosis quística y discinesia ciliar primaria del hospital infantil Dr. Robert Reid Cabral en el período de estudio. Criterios de inclusión: Pacientes mayores de 6 años con diagnóstico confirmado de fibrosis quística y discinesia ciliar primaria (Prueba genética con 2 mutaciones homocigotas, electrolitos en sudor positivos), síntomas respiratorios severos de RSC que no mejoraron con tratamiento convencional y sometidos a la cirugía endoscópica de senos paranasales. Resultados: De un total de 41 pacientes, sólo 10 cumplieron con los criterios de inclusión, el rango de edad más prevalente fue de 14 a 18 años. Tanto los pacientes con FQ como los de DCP disminuyeron la frecuencia de los síntomas de RSC. Posterior a la CEN hubo cambios discretos en la función pulmonar, y sólo los pacientes con enfermedad grave a moderada aumentaron el % de FEV1. La mayoría de los pacientes no ameritaron ingresos posterior a la cirugía. El germen más común encontrado en los cultivos nasofaríngeo y esputo en los pacientes preoperatorios fue la Pseudomonas aeruginosa en el 86%, luego de la CEN hubo un aumento significativo de la colonización por MRSA tanto en los pacientes con FQ como en los de DCP. Más del 50% de los pacientes postquirúrgicos mejoraron su calidad de vida, por lo que la cirugía endoscópica de senos paranasales es efectiva en dicha población en el tratamiento de la rinosinusitis crónica.

Cystic fibrosis: when neonatal screening is unsatisfactory for early diagnosis / Fibrose cística: quando a triagem neonatal é insatisfatória para o diagnóstico precoce

Abstract Introduction: cystic fibrosis newborn screening must enable its earlier diagnosis, which may enhance outcomes. This study was a series case of delayed-diagnosis children submitted to cystic fibrosis newborn screening. Description: fourteen children were included; eight (57.1%) were due to false-negative screening, while six (42.9%) were due to processing errors. Two samples collected after 30 days of life were incorrectly classified as negative, and four infants with a positive test could not be located due to screening processing errors. Cystic fibrosis diagnosis was confirmed at a median (IQR) age of 5.3 (4.2-7.4) months. Poor nutritional status was the most prevalent clinical sign at diagnosis, being present in 78.6% of infants. The mean (SD) weight-for-length and length-for-age Z-scores were -3.46 (0.84) and -3.99 (1.16), respectively. Half of the children had Pseudo-Bartter syndrome, and 42.9% had breathing difficulties. Twelve children (85.7%) required hospitalization, with a median (IQR) length of stay of 17.0 (11.5-26.5) days. Discussion: newborn screening had some faults, from incorrect collections to inefficient active search. Early identification of these children in which screening was unsatisfactory is essential, emphasizing the importance and efforts to not miss them. In the case of a failed test, healthcare professionals must be prepared to recognize the main symptoms and signs of the disease.

Resumo Introdução: a triagem neonatal para fibrose cística deve contribuir para diagnóstico precoce e melhor prognóstico da doença. O estudo é uma série de casos com lactentes submetidos à triagem, porém com diagnóstico tardio da doença. Descrição: quatorze crianças foram incluídas; oito (57,1%) com triagem falso-negativo e seis (42,9%) com erros processuais na triagem neonatal. Duas amostras foram coletadas tardiamente, sendo incorretamente classificadas como negativas e quatro lactentes com triagem positiva não foram localizados, por erros na busca ativa. Confirmou-se o diagnóstico da fibrose cística com idade mediana (IIQ) de 5,3 (4,2-7,4) meses. O Comprometimento nutricional precoce foi o sinal clínico mais prevalente ao diagnóstico, presente em 78,6% das crianças. Os Z escores médios (SD) do peso para altura e altura para idade foram -3,46 (0,84) e -3,99 (1,16), respectivamente. Metade das crianças teve síndrome de Pseudo-Bartter e 42,9% dificuldade respiratória. Doze crianças (85,7%) precisaram hospitalização com tempo mediano de permanência de 17 dias. Discussão: a triagem neonatal para fibrose cística apresentou falhas, desde testes falso-negativos, coletas incorretas, até problemas com a busca ativa. Entretanto, o diagnóstico ágil é essencial e os profissionais de saúde devem reconhecer os sintomas e sinais precoces da doença, mesmo quando a triagem neonatal não for satisfatória.
