First-line therapy with palbociclib in patients with advanced HR+/HER2- breast cancer: The real-life study PALBOSPAIN.

PURPOSE: To evaluate the efficacy and safety of first-line therapy with palbociclib in a Spanish cohort treated after palbociclib approval. METHODS: PALBOSPAIN is an observational, retrospective, multicenter study evaluating real-world patterns and outcomes with 1 L palbociclib in men and women (any menopausal status) with advanced HR+/HER2- BC diagnosed between November 2017 and November 2019. The primary endpoint was real-world progression-free survival (rw-PFS). Secondary endpoints included overall survival (OS), the real-world response rate (rw-RR), the clinical benefit rate, palbociclib dose reduction, and safety. RESULTS: A total of 762 patients were included. The median rw-PFS and OS were 24 months (95% CI 21-27) and 42 months (40-not estimable [NE]) in the whole population, respectively. By cohort, the median rw-PFS and OS were as follows: 28 (95% CI 23-39) and 44 (95% CI 38-NE) months in patients with de novo metastatic disease, 13 (95% CI 11-17) and 36 months (95% CI 31-41) in patients who experienced relapse < 12 months after the end of ET, and 31 months (95% CI 26-37) and not reached (NR) in patients who experienced relapse > 12 months after the end of ET. rw-PFS and OS were longer in patients with oligometastasis and only one metastatic site and those with non-visceral disease. The most frequent hematologic toxicity was neutropenia (72%; grade ≥ 3: 52.5%), and the most common non-hematologic adverse event was asthenia (38%). CONCLUSION: These findings, consistent with those from clinical trials, support use of palbociclib plus ET as 1 L for advanced BC in the real-world setting, including pre-menopausal women and men. TRIAL REGISTRATION NUMBER: NCT04874025 (PALBOSPAIN). Date of registration: 04/30/2021 retrospectively registered.

Evaluación funcional tras SARS-CoV-2 crítico. Estudio de cohortes de la unidad de rehabilitación en un hospital de tercer nivel / Functional evaluation in patient with critical SARS-CoV-2 disease: Cohort study in a third level hospital rehabilitation unit

Introducción: La neumonía por SARS-CoV-2 es una enfermedad infecciosa respiratoria altamente contagiosa que causa disfunción respiratoria, física y psicológica. Presentamos resultados de los pacientes valorados por el Servicio de Rehabilitación al alta de UCI por SARS-CoV-2. Material y método: Estudio de cohortes de pacientes ingresados en UCI por neumonía por SARS-CoV-2 desde el 01/10/2020 al 31/07/2021. Recogemos datos sociodemográficos, antecedentes personales, estancia media en UCI y hospital, Barthel, marcha (FAC) y mMRC (preingreso/valoración inicial/alta), desarrollo de patología osteomuscular y/o neurológica y necesidad de tratamiento rehabilitador. Resultados: Muestra de 341 pacientes de los cuales 224 cumplen criterios. Edad media: 63 años (68,75% hombres). Estancia media UCI/hospital: 27/44 días. Valorados por médicos rehabilitadores, facilitamos a los pacientes una guía elaborada por el equipo médico resolviendo dudas del proceso y pautando ejercicios de intensidad y dificultad progresiva, a realizar durante el ingreso y en el domicilio. El 42,86% desarrolló patología neurológica (83,33% del sistema nervioso periférico). El 100% ha realizado fisioterapia respiratoria y el 72,32% ha precisado fisioterapia motora. Conclusiones: En nuestro estudio, un elevado número de pacientes han precisado tratamiento rehabilitador para su recuperación funcional, destacando el desarrollo de patología neurológica post-COVID. El SARS-CoV-2 genera otras complicaciones, no solo respiratorias, subsidiarias de valorarse y tratarse por los Servicios de Rehabilitación para una recuperación integral que minimice las secuelas.(AU)

Introduction: SARS-COV-2 pneumonia is a highly contagious respiratory disease that causes respiratory, physical and psychological dysfunctions. We present the results of patient assessment when they were discharged from the ICU. Material and method: Cohort study of patients affected by SARS-COV-2 pneumonia admitted to the intensive care unit from 01/10/2020 to 31/07/2021. We collect sociodemographic data, personal history, ICU and hospital stay, Barthel, FAC and mMRC (pre-admission/initial assessment/discharge), development of osteomuscular and/or neurological pathology and need for rehabilitation treatment. Results: A total of 341 patients were evaluated, of which 224 met criteria. The average age was 63 years (68.75% men). Mean ICU/hospital stay were 27/44 days. They were assessed by physiatry, after that, we provide a guide developed by physiatry, solving doubts about the disease and setting exercises of intensity and progressive difficulty, to be carried out during the admission and at home. Neurological pathology was present at 42.86% patients, of whom a 83.33% were peripheral nervous system disease. The total of the sample needed respiratory physiotherapy and a 72.32% motor physiotherapy. Conclusions: In our study, a high number of patients have needed rehabilitation treatment in order to get functional recovery, highlighting the development of post-COVID neurological pathology. SARS-COV-2 generates other complications, not only respiratory, subsidiary to be assessed and treated by rehabilitation services for a comprehensive recovery that minimizes sequelae.(AU)

Beyond image defined risk factors (IDRFs): a delphi survey highlighting definition of the surgical complexity index (SCI) in neuroblastoma.

PURPOSE: Preoperative evaluation of Image Defined Risk Factors (IDRFs) in neuroblastoma (NB) is crucial for determining suitability for upfront resection or tumor biopsy. IDRFs do not all carry the same weighting in predicting tumor complexity and surgical risk. In this study we aimed to assess and categorize a surgical complexity (Surgical Complexity Index, SCI) in NB resection. METHODS: A panel of 15 surgeons was involved in an electronic Delphi consensus survey to identify and score a set of shared items predictive and/or indicative of surgical complexity, including the number of preoperative IDRFs. A shared agreement included the achievement of at least 75% consensus focused on a single or two close risk categories. RESULTS: After 3 Delphi rounds, agreement was established on 25/27 items (92.6%). A severity score was established for each item ranging from 0 to 3 with an overall SCI range varying from a minimum score of zero to a maximum score of 29 points for any given patient. CONCLUSIONS: A consensus on a SCI to stratify the risks related to neuroblastoma tumor resection was established by the panel experts. This index will now be deployed to critically assign a better severity score to IDRFs involved in NB surgery.

An event-based adaptation of the relay feedback experiment for frequency response identification of stable processes.

An event-based modification of the classical relay feedback experiment without the inclusion of additional elements (integrator, time delay, …) for identification of the spectrum of stable processes between zero and the phase cross-over frequency is presented. By inserting an event-based sampler in the control loop, the natural behaviour of a classical relay is simulated and the system is forced to work in two modes. The event-based sampler activates the first mode by sending control actions to the process every time the error signal crosses zero; this mode is to discover the approximated value of the cross-over frequency [Formula: see text] . During the second mode, the event-based sampler sends samples to the process simulating that the error signal crosses zero at [Formula: see text] where N is the number of points to identify in the range [Formula: see text] . One advantage of this procedure is that the logic used in an already existing relay feedback experiment to fit a transfer function model or tune a controller could be maintained just replacing the relay block by the event-based sampler block presented in the paper. Simulations and experiments with different processes and in presence of noise demonstrate the effectivity of the procedure.

A new selection criterion for statistical home range estimation.

The home range of an animal describes the geographic area where this individual spends most of the time while doing its usual activities. From a statistical viewpoint, the problem of home range estimation can be considered as a set estimation one. In the ecological literature, there are a variety of home range estimators. We address the open question of choosing the 'best' home range from a collection of them constructed on the same sample. We introduce the penalized overestimation ratio, a numerical index to rank the estimated home ranges. The key idea is to balance the excess area covered by the estimator (with respect to the sample) and a shape descriptor measuring the over-adjustment of the home range to the data. To our knowledge, apart from computing the home range area, our ranking procedure is the first one both applicable to real data and to any type of home range estimator. Further, optimization of the selection index provides a way to select the tuning parameters of nonparametric home ranges. For illustration purposes, we apply our selection proposal to a dataset of a Mongolian wolf and we carry out a simulation study.

What urethrogram sees and a surgeon does not. / Lo que una uretrografía ve y un cirujano no.

INTRODUCTION: Urethrorrhagia is an infrequent sign in childhood. It should be distinguished from hematuria, since they have a different etiology. CLINICAL CASE: 11-year-old male patient with significant urethrorrhagia. Urinary sediment analysis: red blood cells++. Pelvic ultrasonography: fusiform anechoic image in the corpus spongiosum of the penile root. Retrograde urethrogram: normal anterior urethra, extraluminal contrast passage in the ventral aspect of the bulbar urethra. Cystoscopy: no pathological findings in the urethra or the bladder. Control retrograde urethrogram: cystic dilatation of Cowper's gland duct; Maizels' type 3 perforated syringocele. DISCUSSION: Cowper's syringocele is a rare pathology. It can occur at any stage of childhood in the form of urinary infection, obstructive voiding symptoms, or urethrorrhagia. Urethrogram is key for diagnostic purposes, since most Cowper's syringoceles are detected following urethrogram or cystoscopy. Cases with functional repercussions for the urinary system require surgical treatment. Otherwise, a wait-and-see approach is feasible.

INTRODUCCION: La uretrorragia es un signo infrecuente en la infancia que debe distinguirse de la hematuria dada la diferente etiología de las mismas. CASO CLINICO: Varón de 11 años con uretrorragia franca. Sedimento urinario: hematíes++. Ecografía pélvica: imagen anecoica fusiforme en cuerpo esponjoso de raíz peneana. Uretrografía retrógrada: uretra anterior normal, paso de contraste extraluminal ventral en uretra bulbar. Cistoscopia: sin hallazgos patológicos en uretra ni vejiga. Uretrografía retrógrada de control: dilatación quística del conducto de las glándulas de Cowper; siringocele perforado tipo 3 de Maizels. COMENTARIOS: El siringocele de Cowper es una patología infrecuente que puede debutar en cualquier momento de la infancia como infección urinaria, síntomas miccionales obstructivos o uretrorragia. La uretrografía es fundamental en su diagnóstico ya que la mayoría se objetivan por este medio o cistoscopia. Los casos con repercusión funcional del sistema urinario requieren tratamiento quirúrgico. En caso contrario podrá realizarse actitud expectante.

Calidad de vida en personas con lesión medular de más de 10 años de evolución. La implicación de las complicaciones secundarias / Quality of life in patients with spinal cord injury for at least 10years: Importance of secondary health complications

Objetivo: Determinar la calidad de vida que presentan los lesionados medulares con más de 10 años de evolución. Valorar la prevalencia de complicaciones secundarias y su relación con la calidad de vida y el tiempo desde la lesión. Pacientes y método Diseño: Estudio epidemiológico transversal. Sujetos del estudio Pacientes: con lesión medular traumática, de más 10 años desde la lesión, y que cumplían los criterios de inclusión.Método: calidad de vida se valoró mediante el International spinal cord injury quality of life basic data set. Como variables se incluyeron: factores individuales, déficit neurológico, nivel de lesión y complicaciones secundarias. Resultados: Ciento treinta y un sujetos fueron incluidos en el estudio con edad media de 49 años y un tiempo desde la lesión de 21 años (11-53 años). La media de complicaciones secundarias fue de 2, siendo la más frecuente las urológicas, en 76 sujetos (58%). No existieron diferencias significativas entre el número de complicaciones y el tiempo transcurrido desde la lesión medular. La calidad de vida fue significativamente menor en aquellos que presentaban un mayor número de complicaciones (p = 0,003). Las complicaciones urológicas (p=0,04, IC del 95%, –1,02-2), el dolor musculoesquelético (p=0,01, IC del 95% IC, 1-6), las complicaciones respiratorias (p=0,05, IC del, –3-0,1) y el dolor neuropático que interfería con actividades básicas de la vida (p=0,01, IC del 95%, 1-5) se relacionaban significativamente con una menor calidad de vida. Conclusiones : Las complicaciones secundarias son frecuentes tras la lesión medular, aunque su número no aumenta con el tiempo desde la lesión. La calidad de vida sí está condicionada por la existencia de distintas complicaciones, como la existencia de dolor musculoesquelético.(AU)

Objective: To determine the quality of life of spinal cord injuries with more than 10 years of evolution. Assess the prevalence of secondary complications, and their relationship with quality of life and time since the injury. Patients and method Design: Cross-sectional epidemiological study. Study subjects: Patients with traumatic spinal cord injury, more than 10 years after the injury, and who met the inclusion criteria. Method: Quality of life was assessed using the International spinal cord injury quality of life basic data set. Variables included: individual factors, neurological deficit, level of injury and secondary complications. Results: 131 subjects were included in the study with a mean age of 49 years, and a time since the injury of 21 years (11–53 years). The mean number of secondary complications was 2, the most frequent being urological, in 76 subjects (58%). There were no significant differences between the number of complications and the time elapsed since the spinal cord injury. The quality of life was significantly lower in those with a higher number of complications (P=.003). Urological complications (P=.04, 95% CI: −1.02 to 2), musculoskeletal pain (P=.01, 95% CI: 1–6), respiratory complications (P=.05, 95% CI: −3 to 0.1) and neuropathic pain that interfered with basic life activities (P=.01, 95% CI: 1–5) were significantly related to a lower quality of life. Conclusions: Secondary complications are common after spinal cord injury, although their number does not increase over time after injury. Quality of life is conditioned by the existence of different complications such as the existence of musculoskeletal pain.(AU)

Electronic health records and patient registries in medical oncology departments in Spain

Purpose We aimed to evaluate the current situation of electronic health records (EHRs) and patient registries in the oncology departments of hospitals in Spain. Methods This was a cross-sectional study conducted from December 2018 to September 2019. The survey was designed ad hoc by the Outcomes Evaluation and Clinical Practice Section of the Spanish Society of Medical Oncology (SEOM) and was distributed to all head of medical oncology department members of SEOM. Results We invited 148 heads of oncology departments, and 81 (54.7%) questionnaires were completed, with representation from all 17 Spanish autonomous communities. Seventy-seven (95%) of the respondents had EHRs implemented at their hospitals; of them, over 80% considered EHRs to have a positive impact on work organization and clinical practice, and 73% considered that EHRs improve the quality of patient care. In contrast, 27 (35.1%) of these respondents felt that EHRs worsened the physician–patient relationship and conveyed an additional workload (n = 29; 37.6%). Several drawbacks in the implementation of EHRs were identified, including the limited inclusion of information on both outpatients and inpatients, information recorded in free text data fields, and the availability of specific informed consent. Forty-six (56.7%) respondents had patient registries where they recorded information from all patients seen in the department. Conclusion Our study indicates that EHRs are almost universally implemented in the hospitals surveyed and are considered to have a positive impact on work organization and clinical practice. However, EHRs currently have several drawbacks that limit their use for investigational purposes (AU)

Palbociclib in combination with endocrine therapy versus capecitabine in hormonal receptor-positive, human epidermal growth factor 2-negative, aromatase inhibitor-resistant metastatic breast cancer: a phase III randomised controlled trial-PEARL.

BACKGROUND: Palbociclib plus endocrine therapy (ET) is the standard treatment of hormone receptor-positive and human epidermal growth factor receptor 2-negative, metastatic breast cancer (MBC). However, its efficacy has not been compared with that of chemotherapy in a phase III trial. PATIENTS AND METHODS: PEARL is a multicentre, phase III randomised study in which patients with aromatase inhibitor (AI)-resistant MBC were included in two consecutive cohorts. In cohort 1, patients were randomised 1 : 1 to palbociclib plus exemestane or capecitabine. On discovering new evidence about estrogen receptor-1 (ESR1) mutations inducing resistance to AIs, the trial was amended to include cohort 2, in which patients were randomised 1 : 1 between palbociclib plus fulvestrant and capecitabine. The stratification criteria were disease site, prior sensitivity to ET, prior chemotherapy for MBC, and country of origin. Co-primary endpoints were progression-free survival (PFS) in cohort 2 and in wild-type ESR1 patients (cohort 1 + cohort 2). ESR1 hotspot mutations were analysed in baseline circulating tumour DNA. RESULTS: From March 2014 to July 2018, 296 and 305 patients were included in cohort 1 and cohort 2, respectively. Palbociclib plus ET was not superior to capecitabine in both cohort 2 [median PFS: 7.5 versus 10.0 months; adjusted hazard ratio (aHR): 1.13; 95% confidence interval (CI): 0.85-1.50] and wild-type ESR1 patients (median PFS: 8.0 versus 10.6 months; aHR: 1.11; 95% CI: 0.87-1.41). The most frequent grade 3-4 toxicities with palbociclib plus exemestane, palbociclib plus fulvestrant and capecitabine, respectively, were neutropenia (57.4%, 55.7% and 5.5%), hand/foot syndrome (0%, 0% and 23.5%), and diarrhoea (1.3%, 1.3% and 7.6%). Palbociclib plus ET offered better quality of life (aHR for time to deterioration of global health status: 0.67; 95% CI: 0.53-0.85). CONCLUSIONS: There was no statistical superiority of palbociclib plus ET over capecitabine with respect to PFS in MBC patients resistant to AIs. Palbociclib plus ET showed a better safety profile and improved quality of life.

Ovarian transposition as a minimally invasive fertility preservation technique: ten years of experience in a pediatric center. / La transposición ovárica como técnica de preservación de la fertilidad en edad pediátrica: 10 años de experiencia en un centro de tercer nivel.

INTRODUCTION: Ovarian transposition is a surgical procedure allowing gonadal mobilization from a radiation spotlight to a safer, radiation therapy-free place in patients receiving abdominal or pelvic radiation therapy. And these patients can be managed using minimally invasive surgery. Although some authors have reported good results in fertility preservation with this technique, there are no long-term studies in the pediatric population. We present our results with this procedure in our oncological patients from the last decade. MATERIAL AND METHODS: Retrospective review of medical reports of patients who underwent laparoscopic ovarian transposition in our pediatric oncological surgery unit from 2008 to 2018. The technique varied depending on age, irradiation zone, and concomitant oncological resections. RESULTS: A total of 21 ovarian transpositions were successfully performed in 13 patients. Eight were bilateral, four were left and only one was right. An ovarian cortex cryopreservation was simultaneously carried out in all patients. Eleven procedures were completed laparoscopically, and the suspensory ovarian ligament was divided in sixteen cases. The Fallopian tube was divided in one case, and a simple ovarian transposition was conducted in five cases. Mean hospital stay was 2.4 days, and no complications in the immediate postoperative period were noted. CONCLUSION: Ovarian transposition is a feasible, safe technique. These patients require an extended follow-up to assess ovarian function after oncological treatment.

INTRODUCCION: La transposición ovárica es una técnica quirúrgica que permite alejar los ovarios de la zona de irradiación en pacientes que van a recibir radioterapia abdominal o pélvica. Se han descrito buenas tasas de conservación de función. Sin embargo, no existen estudios en pacientes pediátricos. Presentamos nuestra serie de pacientes intervenidas en nuestro centro. MATERIAL Y METODOS: Estudio retrospectivo de pacientes a las que se le realizó transposición ovárica en nuestra unidad de cirugía oncológica pediátrica entre los años 2008 y 2018. La técnica empleada dependió de la edad, la zona de la irradiación y de la asociación o no con la cirugía del tumor primario. RESULTADOS: Durante el periodo de estudio se realizaron un total de 21 transposiciones ováricas en 13 pacientes (8 bilaterales, 4 izquierdas y 1 derecha). En todos los casos se realizó criopreservación de corteza ovárica dentro del programa de preservación de fertilidad. Once de las 13 intervenciones fueron por laparoscopia, seccionándose el ligamento tubo-ovárico en 16 unidades y en 5 se realizó transposición ovárica simple. La estancia hospitalaria media fue de 2,4 días sin registrarse ninguna complicación en el postoperatorio. Actualmente 9 pacientes continúan seguimiento en sus unidades de oncología pediátrica de referencia, sin haberse notificado ninguna complicación. CONCLUSION: La transposición ovárica es una técnica segura y reproducible. Estas pacientes requieren un seguimiento prolongado para conocer el estado de los ovarios tras el tratamiento oncológico.

Robust switched control of an air levitation system with minimum sensing.

This work studies the control problem of an air levitation system with limited sensing capabilities. We propose a simple but considerably robust switched controller. We prove that the output of the system is globally uniformly ultimately bounded with a bound as small as we desire and we show through simulations and real experiments the robustness of the controller in the presence of disturbances, model uncertainties and parameter tuning.

BOMET-QoL-10 questionnaire for breast cancer patients with bone metastasis: the prospective MABOMET GEICAM study.

BACKGROUND: Bone metastasis (BM) is the most common site of disease in metastatic breast cancer (MBC) patients. BM impacts health-related quality of life (HRQoL). We tested prospectively the psychometric properties of the Bone Metastasis Quality of Life (BOMET-QoL-10) measure on MBC patients with BM. METHODS: Patients completed the BOMET-QoL-10 questionnaire, the Visual Analogue Scale (VAS) for pain, and a self-perceived health status item at baseline and at follow-up visits. We performed psychometric tests and calculated the effect size of specific BM treatment on patients´ HRQoL. RESULTS: Almost 70% of the 172 patients reported symptoms, 23.3% experienced irruptive pain, and over half were receiving chemotherapy. BOMET-QoL-10 proved to be a quick assessment tool performing well in readability and completion time (about 10 min) with 0-1.2% of missing/invalid data. Although BOMET-QoL-10 scores remained fairly stable during study visits, differences were observed for patient subgroups (e.g., with or without skeletal-related events or adverse effects). Scores were significantly correlated with physician-reported patient status, patient-reported pain, symptoms, and perceived health status. BOMET-QoL-10 scores also varied prospectively according to changes in pain intensity. CONCLUSIONS: BOMET-QoL-10 performed well as a brief, easy-to-administer, useful, and sensitive HRQoL measure for potential use for clinical practice with MBC patients.

Characteristics of the puberty in hair ram lambs and its crosses in Colombia under low altitude conditions / Características de la pubertad en corderos de pelo y sus cruces en Colombia en condiciones de baja altitud

ABSTRACT Objective. Aimed to describe the characteristics of the onset of puberty in males in Colombian hair ram lambs (Ovino de Pelo Colombiano, OPC), and their crosses with Katahdin and Santa Inés sheep in a farm located in Villavicencio, Meta. Materials and methods. 15 lambs of three biotypes: OPC x OPC (OPC), Santa Ines x OPC (SO) and Katahdin X OPC (KO) from four until 12 months old. Ram lambs were grazing and they had supplementation with commercial salt and water ad libitum. Monthly body weight (BW), scrotal circumference (SC), testicular volume (TV) were measured and testosterone level were determined by Elisa test, and ultrasound of the two testicles was performed to determine the presence of the testicular mediastinum, also evaluating the presence and detachment of the urethral prolongation and then electro ejaculation was performed to determine the macroscopic and microscopic characteristics of the semen. Results. Genotype effect was significant for evolution of body BW, SC, TV over time. The SO and KO crosses presented the highest values in BW, whereas OPC lambs maintained a lower value until the end of the assay. At six months old, the three biotypes presented a minimum concentration of 150 million of sperm per ml with 30% of individual progressive motility. Conclusions. In non-seasonal tropical conditions in Colombia (Orinoquia), depending on the variables included, body weight, testicular development, pennis morphology, semen quality, sperm concentration and testosterone levels, it is postulated that around six months of age, the onset of puberty is displayed in the three biotypes.

RESUMEN Objetivo. Describir las características del inicio de la pubertad en corderos machos (Ovino de Pelo Colombiano, OPC) y sus cruces en una granja ubicada en Villavicencio, Meta. Materiales y métodos. Se evaluaron 15 corderos de tres razas: OPC x OPC (OPC), Santa Inés x OPC (SO) y Katahdin X OPC (KO), a partir de los cuatro meses de edad, cinco corderos por cruzamiento, manejados en pastoreo rotacional, con sal mineralizada comercial y agua a voluntad. Mensualmente hasta los doce meses de edad, se evaluó el peso corporal (PC), circunferencia escrotal (CE), volumen testicular (VT), y se determinó la concentración de testosterona en suero mediante la prueba de Elisa, se determinó la presencia del mediastino testicular mediante ecografía y se evalúo el desprendimiento de la prolongación uretral. Finalmente se determinaron las características macroscópicas y microscópicas del eyaculado. Resultados. El efecto racial o de cruzamiento fue significativo para los resultados del PC, CE y VT en el tiempo. Los cruces OPC y KO presentaron los valores más altos en PC, mientras que los corderos OPC mantuvieron un valor menor de PC hasta el final de la investigación. Se realizaron al menos cuatro evaluaciones seminales hasta la presentación de una concentración mínima de 150 millones de espermatozoides por ml con un 30% de motilidad progresiva individual. Conclusiones. En condiciones tropicales no estacionales en Colombia (Orinoquia), para las variables peso corporal, desarrollo testicular, morfología del pene, calidad del semen, concentración de espermatozoides y niveles de testosterona, se postula que alrededor de los seis meses de edad, se presenta el inicio de la pubertad en los tres biotipos.

Un lactante con neumatosis intestinal y neumoperitoneo: la difícil decisión de no intervenir / An infant with intestinal pneumatosis and pneumoperitoneum: the difficult decision not to intervene

El neumoperitoneo en niños puede deberse a causas que no requieran cirugía urgente, como maniobras de reanimación cardiopulmonar, patología respiratoria grave o ventilación mecánica. Intervenir en estos casos podría, incluso, empeorar el pronóstico. Presentamos el caso clínico de un lactante varón, exprematuro, con antecedente al nacer de enterocolitis necrotizante y perforación ileal, que precisó laparotomía y resección intestinal en dos ocasiones y que desarrolló un microcolon por desuso secundario. A los seis meses, tras iniciar alimentación oral exclusiva, presentó distensión abdominal con extensa neumatosis intestinal y neumoperitoneo en las radiografías. Su aspecto era bueno con tránsito intestinal conservado y ausencia de peritonitis. El paciente se mantuvo a dieta absoluta con antibioterapia endovenosa, sondaje nasogástrico y nutrición parenteral. La evolución fue favorable, reiniciando la alimentación oral a los siete días del ingreso. La existencia de un neumoperitoneo no siempre obliga a realizar una laparotomía, y la valoración global del enfermo por un equipo multidisciplinar puede evitar tratamientos agresivos innecesarios

Pneumoperitoneum in children may be due to causes that do not require urgent surgery (cardiopulmonary resuscitation manoeuvres, severe respiratory pathology or mechanical ventilation). Surgery in these cases could even worsen the prognosis. We present the case of a male infant, ex-preterm, with a history of necrotizing enterocolitis and ileal perforation at birth, requiring laparotomy and intestinal resection on two occasions and developing a secondary microcolon, due to disuse. At six months, after transitioning to full oral feeding, he presented abdominal distension with extensive intestinal pneumatosis and pneumoperitoneum on radiographs. His general appearance was good with normal intestinal transit and no peritonitis. The patient remained fasting with intravenous antibiotics, nasogastric decompression and parenteral nutrition. The evolution was favourable with oral feeding restarting on the seventh day of admission. The existence of pneumoperitoneum does not always require a laparotomy and global assessment of the patient by an interdisciplinary health team may avoid unnecessary aggressive treatments
