- Abstract
Los tumores hipofisarios (TH) suponen el 15% de los tumores intracraneales, y afectan del 10,7 al 14,4% de la población, si bien la incidencia de los TH clínicamente relevantes es de 5,1 casos/100.000 habitantes. El tratamiento quirúrgico está indicado en los TH que cursan con hipersecreción hormonal (a excepción de los TH productores de prolactina), así como en aquellos con clínica compresiva local o neurológica global. Los pacientes con TH requieren una atención multidisciplinar, idealmente en un centro de excelencia y basada en un protocolo asistencial bien definido. Con el objetivo de facilitar y estandarizar la práctica clínica ante este tipo de tumores, el presente documento recoge el posicionamiento del ÿrea de Conocimiento de Neuroendocrinología de la Sociedad Española de Endocrinología y Nutrición (SEEN) y la Sociedad Española de Neurocirugía (SENEC) sobre el manejo y el seguimiento prequirúrgico, quirúrgico y posquirúrgico del paciente con un TH. Pituitary tumors (PT) account for 15% of intracranial tumors affect 10.7 to 14.4% of the population although the incidence of clinically relevant PT is 5.1 cases/100,000 inhabitants. Surgical treatment is indicated in PTs with hormone hypersecretion (except for prolactin-producing PTs) and those with local compressive or global neurological symptoms. Multidisciplinary care, is essential for patients with PTs, preferably delivered in a center of excellence and based on a well-defined care protocol. In order to facilitate and standardize the clinical procedures for this type of tumor, this document gathers the positioning of the Neuroendocrinology Knowledge Area of the Spanish Society of Endocrinology and Nutrition (SEEN) and the Spanish Society of Neurosurgery (SENEC) on the management of patients with PTs and their preoperative, surgical and postoperative follow-up.

Cushing's syndrome (CS) rarely occurs during pregnancy due to the influence of the hypercortisolism on the reproductive axis, with only a few cases described. We present a case of a 32 years-old woman diagnosed with ACTH-dependent CS and no clear pituitary lesion on the MRI. She was on ketoconazole when she discovered she was 8-weeks pregnant. Ketoconazole was stopped and a conservative management was decided. At 26 weeks of gestation, the patient developed gestational diabetes and treatment with metyrapone was started. Metyrapone was well tolerated and the pregnancy proceeded without further complications. She gave birth to a male infant, via cesarean section, at 36 weeks, with no apparent teratogenic effects of metyrapone. Many authors consider surgery as the first-choice treatment in pregnant women with CS but there is no consensus on the best management in such patients. Pharmacological treatment with metyrapone may be a safe and effective alternative. [ABSTRACT FROM AUTHOR]

Cushing disease (CD), although rare, is a life-threatening disorder caused by an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma, which leads to excess adrenal-derived cortisol. Efficacious and safe medical therapies that control both hormonal hypersecretion and pituitary corticotroph tumor growth remain an unmet need in the management of CD. Translational research in pituitary tumors has been significantly hampered by limited quantities of surgically resected tissue for ex vivo studies, and unavailability of human pituitary tumor cell models.To characterize human corticotroph tumors at the cellular level, we employed single cell RNA-sequencing (scRNA-seq) to study 4 surgically resected tumors. We also used microarrays to compare individualized paired consecutive culture passages to understand transcriptional shifts as in vitro cultures lost ACTH secretion. Based on these findings, we then modified our in vitro culture methods to develop sustained ACTH-secreting human corticotroph tumoroid cultures.scRNA-seq identified 4 major cell populations, namely corticotroph tumor (73.6%), stromal (11.2%), progenitor (8.3%), and immune cells (6.8%). Microarray analysis revealed striking changes in extracellular matrix, cell adhesion and motility-related genes concordant with loss of ACTH secretion during conventional 2D culture. Based on these findings, we subsequently defined a series of crucial culture nutrients and scaffold modifications that provided a more favorable trophic and structural environment that could maintain ACTH secretion in in vitro human corticotroph tumor cultures for up to 4 months.Our human corticotroph tumoroid model is a significant advance in the field of pituitary tumors and will further enable translational research studies to identify critically needed therapies for CD.This work was partly funded by NCI P50-CA211015 and the Warley Trust Foundation.

- Abstract
Resumen Introducción Los tumores hipofisarios y de la región selar representan el 10-15% de los tumores benignos intracraneales, siendo los adenomas los más frecuentes. En el siguiente artículo exponemos la experiencia adquirida a lo largo de 9 años en el tratamiento quirúrgico por vía endoscópica de lesiones selares. Explicaremos los aspectos característicos de nuestra técnica quirúrgica y los resultados en términos clínicos y hormonales. Material y métodos Realizamos un estudio retrospectivo de 200 pacientes con lesiones selares intervenidos por un único neurocirujano (J.E.) mediante abordaje endoscópico endonasal transesfenoidal entre febrero de 2006 y febrero 2015. No se incluyen abordajes extendidos a la base craneal, craneofaringiomas, ni lesiones inflamatorias, metastásicas o malignas. Resultados De 200 pacientes, 7 eran quistes de Rathke y 193 adenomas (26 microadenomas y 165 macroadenomas). Subclasificados estos, a su vez, según el grado de invasión del seno cavernoso (Knosp 0, 1 y 2: 129 casos; Knosp 3 y 4: 71 casos). Se consiguió una exéresis tumoral completa en 143 pacientes (71,5%), subtotal en 39 (19,5%) y parcial en 18 (9%). En el grupo de mayor ocupación del seno cavernoso (Knosp 3 y 4) se consiguió una resección completa en un 55,5% (40/71). Se logró una remisión hormonal en 34 pacientes (85%) con acromegalia, en 23 (76%) con prolactinomas y en 30 (86%) con enfermedad de Cushing. Conclusión Los resultados obtenidos en nuestra serie, fruto de la centralización y la experiencia, son equiparables a los mejores resultados conseguidos en centros de referencia de cirugía hipofisaria. La exploración quirúrgica precoz de la fístula reduce la tasa de meningitis posquirúrgicas. Introduction Pituitary and sellar region tumours account for 10-15% of intracranial benign tumours, with pituitary adenoma being the most common one. In this article, a review is presented on 9 years of experience in surgical treatment using an endoscopic approach of sellar region lesions. The main features of our surgical technique will be explained, as well as the results in clinical and hormonal terms. Material and methods A retrospective analysis was conducted on 200 patients operated on due to sellar lesions by the same neurosurgeon (J.E.) using an endoscopic endonasal transsphenoidal approach between February 2006 and February 2015. The cases excluded were, those requiring extended approaches of the skull base, as well as craniopharyngiomas, inflammatory, metastatic, or malignant lesions. Results Of the 200 patients treated (59.5% women, mean age of 51.7 years, range: 18-82 years old), there were: 7 Rathke cysts and 193 adenomas (26 micro-adenomas and 165 macro-adenomas). All of them sub-classified according to the degree of invasion of the cavernous sinus (Knosp 0, 1, and 2: 129 cases and Knosp 3 and 4: 71 cases). Total resection was achieved in 143 patients (71.5%), subtotal resection in 39 (19.5%), and partial resection in 18 (9%). In the group of higher occupancy of the cavernous sinus (Knosp 3 and 4) complete resection was achieved in 55.5% (40 of 71 patients). Hormonal remission was achieved in 34 patients with acromegaly (85%), 23 patients with prolactinomas (76%), and 30 patients with Cushing's disease (86%). Conclusion The results obtained in our series, due to the centralisation of pathology and experience, are comparable to those achieved in pituitary surgery reference centres. Early surgical exploration of cerebrospinal fluid leaks reduces the risk of post-surgical meningitis. [ABSTRACT FROM AUTHOR]

- Abstract
Resumen Introducción En los últimos años la radiocirugía (RC) se ha postulado como una buena alternativa terapéutica, por lo general de segunda línea, en el manejo de los adenomas hipofisarios productores de ACTH. Se realiza un estudio retrospectivo para evaluar la eficacia y la seguridad de dicho tratamiento en estos pacientes. Material y métodos Se recogieron datos de los pacientes tratados mediante RC por adenoma hipofisario productor de ACTH entre 1996 y 2008, con al menos un año de seguimiento, analizando la tasa de normalización hormonal y mejoría clínica (estigmas del síndrome de Cushing, hipertensión arterial), así como la aparición de efectos adversos y de recidiva. Se consideró normalización hormonal —y por tanto curación— como una tasa normal de cortisol libre urinario (CLU) en 24 h (< 100 μg/día). Resultados Treinta pacientes fueron tratados, de los que 24 entraron en el estudio. Todos ellos tenían cifras elevadas de CLU previamente al tratamiento con RC. La curación se consiguió en 12 (50%), en un promedio de 28 meses, y en otros 3 pacientes se normalizaron las cifras de CLU con tratamiento con ketoconazol posterior. En todos mejoraron los estigmas de Cushing, y en 13 (de 14) mejoró la HTA. No se evidenció ningún caso de recidiva una vez instaurada la curación. Entre las complicaciones destacan 9 déficits hormonales nuevos (siendo el más frecuente el hipotiroidismo), una radionecrosis y un empeoramiento de la campimetría previa. No se encontró ningún caso de tumor radioinducido. Conclusiones La RC es un tratamiento efectivo para aquellos pacientes con adenoma productor de ACTH en que la cirugía ha fallado o que no son candidatos a la misma, consiguiéndose buenas tasas de normalización hormonal y de control clínico de la enfermedad, con un bajo porcentaje de efectos adversos. Background In the past few years, stereotactic radiosurgery (SRS) has been suggested as a good alternative, second line therapy for the management of patients with ACTH-secreting pituitary adenomas. A retrospective study has been conducted in order to evaluate the efficacy and safety of this treatment in these patients. Material and methods Data were collected on all patients treated with SRS for an ACTH-secreting pituitary adenoma between 1996 and 2008, and with at least one year of follow-up. An analysis was carried out by analysing the return to normal of the hormone levels and clinical improvement rates (including Cushing signs, arterial hypertension), as well as adverse effects, and disease relapse. A return to normal of the 24 hour urinary free cortisol (24-UFC) levels (< 100 μg/day) without any ACTH-secretion suppressor drug treatment, was considered as cure or improvement. Results A total of 30 patients were treated with SRS, of which 24 were included in the analysis. They all had high 24-UFC levels before the treatment. Cure was achieved in 12 (50%) in a mean of 28 months, and in other 3 patients 24-UFC levels returned to normal with treatment with ketoconazole after the SRS. Cushing signs improved in all cases, as well as arterial hypertension in 13 out of 14 cases. There were relapses after cure consolidation. As far as adverse effects, it should be mentioned that there were 9 cases of new pituitary hormonal dysfunction (the most frequent being hypothyroidism), one radionecrosis, and one case of visual field defect impairment. Radiation-related neoplasm was not detected in any of the cases. Conclusions SRS is an effective treatment for those patients with ACTH-secreting pituitary adenoma in whom surgery has failed, or in those that are not good candidates for it. It showed good rates of hormone levels returning to normal, as well as clinical disease control and a low level of adverse effects. [ABSTRACT FROM AUTHOR]

La pandemia por síndrome respiratorio agudo severo por infección por coronavirus 19 (SARS-COVID19) representa un gran reto para los sistemas de salud mundiales. El distanciamiento social y la cuarentena han afectado la forma del cuidado de pacientes con patología hipofi saria y adrenal. El cuidado de estos pacientes requiere un equipo multidisciplinario de especialistas, a menudo con casos complejos para diagnóstico y tratamiento, incluyendo la cirugía hipofi saria. La disrupción y los requerimientos de adaptación ante la pandemia hacen necesario proveer una guía del cuidado adecuado de estos pacientes a nivel local con nuestros recursos. The pandemic by acute severe respiratory syndrome for coronavirus 19 (SARS-COVID19) represents a big challenge for health systems worldwide. Social distancing and quarantine have affected usual care of patients with pituitary and adrenal disease. Care for these patients requires a multidisciplinary team of specialists, frequently with complex cases for diagnoses and treatment, including pituitary surgery. Disruption and adapting to these requirements in light of this pandemic makes a need for providing care guidance for these patients on a local level with our resources. 39-44 mevelasque@gmail.com Cuatrimestral http://www.saber.ula.ve/rvem/

Secondary osteoporosis is a frequently underestimated bone disorder. It is a secondary cause of bone loss that affects more than half of men and premenopausal and perimenopausal women, and about one-fifth of postmenopausal women. We herein report an uncommon case of multiple fractures due to secondary osteoporosis caused by Cushing's disease. In this case the appearance of fractures in a 41 years old woman was the sign of alarm that ultimately led us to the diagnosis. [ABSTRACT FROM AUTHOR]
