Computational model based on optical coherence tomography (OCT) skin scanning to identify and quantify acute radiation dermatitis (ARD): a prospective diagnostic study.

BACKGROUND: acute radiation dermatitis (ARD) is the most widely reported radiotherapy-induced adverse event. Currently, there is no objective or reliable method to measure ARD. OBJECTIVE: our main objective was to identify and quantify the effects of radiotherapy with a computational model using optical coherence tomography (OCT) skin scanning. Secondary objectives included determining the ARD impact of different radiotherapeutic schemes and adjuvant topical therapies. METHODS: we conducted a prospective, single-center case series study in a tertiary referral center of patients with breast cancer who were eligible for whole breast radiotherapy (WBRT). RESULTS: a total of 39 women were included and distributed according to the radiotherapeutic schemes (15, 20, and 25 fractions). A computational model was designed to quantitatively analyze OCT findings. After radiotherapy, OCT scanning was more sensitive revealing vascularization changes in 84.6% of the patients (vs 69.2% of the patients with ARD by clinical examination). OCT quantified an increased vascularization at the end of WBRT (P < .05) and a decrease after 3 months (P = .032). Erythematous skin changes by OCT were more pronounced in the 25-fraction regime. CONCLUSION: an OCT computational model allowed for the identification and quantification of vascularization changes on irradiated skin, even in the absence of clinical ARD. This may allow the design of standardized protocols for ARD beyond the skin color of the patients involved.

Immediate release fentanyl. Real world data on abuse and dependence in Spain / Fentanilo de liberación inmediata. Datos de vida real de abuso y dependencia en España

Purpose: A substantial increase in the prescription of immediate release fentanyl (IRF) outside hospitals was observed in previous studies between 2012 and 2017, however it remains unknown the extent of immediate release fentanyl use disorders (IRFUD). This study aimed to estimate the incidence and risk factors of IRFUD, such us abuse and dependence, in Spain during this period. Methods: Retrospective cohort study performed in a Spanish electronic primary care healthcare records database (BIFAP). The incidence rate of IRFUD was calculated by dividing the number of incident cases by the total patient-years (p-y) of exposure. Demographic data, lifestyle, cancer diagnosis, comorbidities and concomitant medication were described and analyzed overall and in patients developing IRFUD using Cox regression models. Effect of the type of treatment (continuous/discontinuous) and duration were also evaluated. Results: The incidence of IRFUD in the 12,267 patients analyzed was 1.8 cases per 100 p-y of exposure. Baseline analysis showed higher frequencies of IRFUD for smokers, patients with a history of substance abuse, non-oncology indication and diagnosis of depression and anxiety, respect to non-IRFUD patients. Patients aged ≥ 80 were less likely to develop IRFUD abuse/dependence. Significant differences were for concomitant use of other treatments with potential for dependence and abuse, such as benzodiazepines. The risk of IRFUD increased with treatment duration, being the highest for treatments lasting 180 days and longer. Conclusion: Incidence of IRFUD is difficult to contrast due to the lack of similar studies. It could be considered not too higher outside hospitals but possible in cancer and non-cancer patients...

En estudios previos se ha observado un aumento considerable en la prescripción de fentanilo de liberación inmediata en el ámbito extrahospitalario entre 2012 y 2017. Sin embargo, aún se desconoce la magnitud de dependencia y abuso derivada de su uso. Este estudio tiene como objetivo estimar la incidencia y los factores de riesgo de los trastornos derivados del uso de fentanilo de liberación inmediata en España, tales como el abuso y la dependencia durante este período. Métodos: Estudio de cohortes retrospectivo realizado en España en la base de datos de historias clínicas electrónicas de atención primaria (BIFAP). La tasa incidencia de trastornos por el uso de fentanilo, se calculó dividiendo el número de casos incidentes entre el total de personas-año de exposición. Se analizaron datos demográficos, estilo de vida, diagnóstico de cáncer, comorbilidades y medicación concomitante. Para el análisis se utilizaron modelos de regresión de Cox. También se evaluó el efecto del tipo de tratamiento (continuo/discontinuo) y la duración de tratamiento. Resultados:La incidencia de trastornos por el uso de fentanilo en los 12,267 pacientes analizados fue de 1.8 casos por 100 personas-año de exposición. Se observó una frecuencia más elevada en aquellos pacientes que al inicio del tratamiento eran fumadores, pacientes con antecedentes de abuso de sustancias, con indicaciones no oncológicas y en pacientes con diagnóstico de depresión y ansiedad en comparación con los pacientes que no desarrollaron el evento. Los pacientes mayores de 80 años presentaron menos probabilidades de desarrollar estos trastornos. Se observaron diferencias significativas en el uso concomitante con otros tratamientos con potencial de desarrollar dependencia y abuso, como las benzodiacepinas. El riesgo aumentó con la duración del tratamiento, siendo más elevado para aquellos tratamientos que duraban 180 días o más... (AU)

Compartments of the crural fascia: clinically relevant ultrasound, anatomical and histological findings.

PURPOSE: Compartment syndrome is a surgical emergency that can occur in any part of the body and can cause cell necrosis when maintained over time. The resulting defects can affect the nerves, muscle cells, bone tissue, and other connective tissues inside the compartment, and fasciotomy has to be performed. The anatomical and histological characteristics of the leg make acute, chronic, and exertional compartment syndrome more likely in this limb. For these reasons, knowledge of the ultrasound, anatomical, and histological features of the crural fascia can help in the treatment of leg compartment syndrome. METHODS: Twenty-one cryopreserved lower limbs from adult cadavers and from one 29-week-old fetus were obtained from the dissection room. They were examined by ultrasound and a subsequent anatomical dissection and microscopy to study the crural fascia and its relationship with the different muscles. Anthropometric measurements were taken of the distances from the head of the fibula and lateral malleolus to the origin of the tibialis anterior muscle in the crural fascia, the exit of the superficial fibular nerve, and the fascia covering the deep posterior muscles of the leg. RESULTS: The crural fascia has very important clinical relationships, which can be identified by ultrasound, as the origin of the tibialis anterior muscle at 16.25 cm from the head of the fibula and the exit of the superficial fibular nerve that crosses this fascia at 21.25 cm from the head of the fibula. Furthermore, the presence of a septum that fixes the deep posterior muscles of the leg and the vessels and nerve can be seen by ultrasound and can explain the possible development of a posterior compartmental syndrome of the leg. Awareness of these features will help to keep these structures safe during the surgical treatment of compartment syndrome. CONCLUSION: The ultrasound study allows identification of anatomical structures in the leg and, thus, avoids damage to them during surgery for compartmental syndromes.

Treatment of pectus excavatum with vacuum bell during puberty. / Tratamiento del pectus excavatum con campana de succión durante la pubertad.

OBJECTIVE: To assess the efficacy of the vacuum bell during puberty, according to the daily hours of use and treatment duration. MATERIALS AND METHODS: A retrospective analysis of patients treated with vacuum bell during puberty in the 2010-2021 period was carried out. Several variables were collected, including baseline and final sinking, repaired sinking expressed in cm and as a percentage from baseline sinking, daily hours of use, treatment duration, and complications. Patients were categorized into groups according to the daily hours of use (≤ 3 hours; 4-5 hours; ≥ 6 hours) and treatment duration (6-12 months; 13-24 months; 25-36 months; > 36 months), and they were statistically analyzed. RESULTS: A total of 50 patients -41 male and 9 female- were studied, with a mean age of 12.5 years (range: 10-14 years). No significant differences among groups were observed in terms of baseline sinking, thoracic index, and final sinking. Repaired sinking did increase with the daily hours of use, with significant differences. Complications were mild. 3 patients withdrew from follow-up, and 5 out of the 25 patients who completed treatment achieved a good repair. CONCLUSIONS: To increase treatment efficacy, the vacuum bell should be used for 6 hours/day during puberty. This method is well-tolerated, causes mild complications, and may be an alternative to surgery in some cases.

Development and validation of a minimally invasive and image-guided tape stripping method to sample atopic skin in children.

BACKGROUND: Molecular skin profiling techniques, typically performed on skin samples taken by punch biopsy, have enhanced the understanding of the pathophysiology of atopic dermatitis (AD), thereby enabling the development of novel targeted therapeutics. However, punch biopsies are not always feasible or desirable, and novel minimally invasive methods such as skin tape stripping have been developed. AIM: To develop, optimize and validate a novel tape stripping method guided by noninvasive in vivo skin imaging to sample atopic skin in children. METHODS: Skin tape stripping-based procedures were compared and optimized using data from 30 healthy controls (HCs: 5 adults, 25 children) and 39 atopic children. Evaluations were guided by high-resolution photography, reflectance confocal microscopy, optical coherence tomography and transepidermal water loss measurements. We assessed and compared adverse events (AEs), the time needed to perform the sampling and the cDNA levels obtained from the tapes. RESULTS: Tape stripping methods based on previously described protocols resulted in erosions in all participants and required a median time of 65 min to perform (range 60-70 min), but provided good cDNA yield. Shorter durations appeared less invasive but provided lower cDNA yield. The final optimized tape stripping protocol, using 11 tapes of 22 mm in diameter, each applied twice for 5 s with 90° rotation, did not produce significant AEs, was completed within a median time of 7 min (range 5-15 min) and provided good cDNA yield both in HCs and atopic children. CONCLUSION: Our minimally invasive method is safe and reliable, and provides reproducible acquisition of cDNA in atopic children. In addition, it enables rapid sample collection, a crucial factor in clinical practice.

Cronotaraxis como síntoma guía de un infarto talámico medial / Chronotaraxis as a harbinger of medial thalamic infarction

La cronotaraxis es una afectación de la percepción de la secuencia temporal. Esta alteración de la temporalidad se ha descrito asociada de forma característica a la afectación talámica, concretamente al núcleo dorsomediano. Casos clínicos. Presentamos los casos clínicos de dos pacientes con ictus isquémicos agudos de localización en dicho territorio, con una clínica basada en este síntoma y cuyo reconocimiento resultó esencial en el abordaje terapéutico. Tanto en el primero como en el segundo caso se describe cómo la percepción de la temporalidad fue esencial para el diagnóstico de la patología isquémica de ambos pacientes. Discusión. El conocimiento y la divulgación de esta asociación pueden resultar fundamentales en el manejo de los pacientes con alteraciones talámicas. Esto se debe a la posibilidad que surge de influir y modificar el abordaje inicial, puesto que el reconocimiento de un síntoma específico, como es la cronotaraxis, puede evitar la extensión del daño talámico, y prevenir de esta manera las secuelas, sobre todo cognitivas, que ocasiona a largo plazo.(AU)

Introduction: Chronotaraxis is an impairment of the perception of the sequencing of time. This alteration of temporality has been described as being characteristically associated with thalamic involvement, specifically in the dorsomedial nucleus. Case reports: We report the clinical cases of two patients with acute ischaemic strokes located in said territory, with a clinical presentation based on this symptom and the recognition of which was essential in the therapeutic approach. In the first and second cases, it is described how the perception of temporality was essential for the diagnosis of the ischaemic condition in both patients. Discussion: Awareness and dissemination of this association may be vital in the management of patients with thalamic disorders. This is due to the possibility of influencing and modifying the initial approach, since the recognition of a specific symptom, such as chronotaraxis, can prevent the spread of thalamic damage, in addition to the long-term sequelae that it causes, especially those of a cognitive nature.(AU)

Postoperative hyperlipasemia in perforated appendicitis in children. / Hiperlipasemia posoperatoria en apendicitis perforada en niños.

OBJECTIVE: The objective of this study was to assess the hyperlipasemia cases detected in the postoperative period of perforated appendicitis. MATERIALS AND METHODS: A retrospective analysis of the perforated appendicitis cases occurred in our institution over a 7-year period (2013-2019) was carried out. Only cases where preoperative and postoperative serum lipase levels were available were included. The variables collected were statistically assessed by means of a descriptive, univariate analysis. RESULTS: A total of 88 patients were studied. They were divided into 3 groups according to postoperative lipase levels - 57 were allocated to Group 1 (lipase: 70-194.0 U/L, normal range), 20 were allocated to Group 2 (lipase: 195-582 U/L), and 11 were allocated to Group 3 (lipase: > 582 U/L, which triples normal levels). Statistically significant differences were found in the following variables: sex, postoperative abscess, postoperative subocclusion/intestinal occlusion, preoperative lipase levels, days of parenteral nutrition, days of ICU stay, and days of hospital stay. Postoperative lipase had a moderate correlation with preoperative lipase, and none of the cases met acute pancreatitis diagnostic criteria. CONCLUSIONS: Hyperlipasemia in the postoperative period of perforated appendicitis is not associated with developing clinical pancreatitis, but it is associated with worse progression in terms of increased complications, such as subocclusion/intestinal occlusion and intra-abdominal abscess, and longer ICU stay, hospital stay, and parenteral nutrition. There is a moderate correlation between preoperative and postoperative lipase, which means they could both prove useful as prognostic markers.

OBJETIVO: El objetivo del estudio es evaluar los casos de hiperlipasemia detectados en el posoperatorio de la apendicitis perforada. MATERIAL Y METODO: Se evaluaron retrospectivamente los casos de apendicitis perforada en nuestro centro durante 7 años (2013-2019), seleccionando aquellos con mediciones preoperatorias y posoperatorias de lipasa sérica. Las diferentes variables recogidas se analizaron estadísticamente de manera descriptiva y univariante. RESULTADOS: Se estudiaron un total de 88 pacientes que se dividieron en tres grupos según el valor de la lipasa posoperatoria: 57 corresponden al grupo 1 (lipasa 70-194 U/L, rango normal), 20 al grupo 2 (lipasa 195-582 U/L) y 11 al grupo 3 (lipasa > 582 U/L, valor tres veces por encima del normal). Las variables que mostraron diferencias estadísticamente significativas fueron el sexo, el absceso posoperatorio, la suboclusión/oclusión intestinal posoperatoria, la lipasa preoperatoria, los días de nutrición parenteral, los días de ingreso en UCI y los días de estancia hospitalaria. La lipasa posoperatoria mostró una correlación moderada con la lipasa preoperatoria y ningún caso cumplió criterios diagnósticos de pancreatitis aguda. CONCLUSIONES: La hiperlipasemia en el posoperatorio de la apendicitis perforada no se asocia al desarrollo de pancreatitis clínica, pero sí se asocia a una peor evolución en relación con un aumento de complicaciones, como la suboclusión/oclusión intestinal y el absceso intraabdominal, y un mayor número de días de ingreso en UCI, de días de nutrición parenteral y de estancia hospitalaria. Existe una moderada correlación entre la lipasa preoperatoria y posoperatoria, de modo que ambas podrían ser útiles como marcadores pronósticos.

Effect of pituitary adenoma consistency on surgical outcomes in patients undergoing endonasal endoscopic transsphenoidal surgery.

BACKGROUND: Most pituitary adenomas (PAs) are considered to have a soft tumor consistency. However, there is a non-negligible percentage (5-13%) of tumors presenting or exhibiting a fibrous consistency that would entail a more difficult and complicated surgical excision with higher surgical morbidity and mortality rates. PURPOSE: To analyze the clinical consequences of PA tumor consistency on the surgical outcomes in patients undergoing endonasal endoscopic transsphenoidal (EET) pituitary surgery. METHODS: An ambispective study of patients with PAs operated on through an EET approach in two Spanish tertiary hospitals over the last 12 years. A total of 226 consecutive interventions were carried out in the Neurosurgery Departments of the Hospital Universitario Ramón y Cajal (HURC) and the Hospital Universitario Puerta del Sur by the same neurosurgeon. PAs were grouped into soft (n = 150) and fibrous (n = 76). All patients underwent hormonal and magnetic resonance imaging (MRI) studies before and after surgery. In addition, neurosurgical complications were recorded in each patient. RESULTS: Fibrous adenomas were independently associated with lower resection rates compared to soft adenomas (fibrous gross total resection [GTR] rate 48.7% vs. 76.3%, p < 0.001), even in those adenomas without invasion of the cavernous sinus (Knosp grades 0, I, and II). There were more intraoperative cerebrospinal fluid (CSF) leaks in patients with fibrous PAs. Moreover, fibrous PAs showed higher rates of postoperative hypopituitarism, permanent diabetes insipidus (DI) and postoperative treatments (hormonal treatment and radiotherapy). The excision of a fibrous PA required a longer surgical time (22.5 min more than soft PAs, p = 0.014), regardless of other factors. CONCLUSION: The consistency of the PAs significantly conditions both the results of surgery (lower resections rates), complications (higher incidence of postoperative hypopituitarism, permanent DI), and the prognosis (higher incidence of postoperative treatments) of the patient undergoing EET.

Tail posture and motion in relation to natural behaviour in juvenile and adult pigs.

The tail of pigs has been suggested as a welfare indicator as it can provide insight into a pig's behavioural and emotional states. Tail posture and motion have so far mainly been studied in the context of tail biting behaviour. The aim of this study was to investigate the relationship between pigs' natural behaviour and their tail posture and tail motion. This was studied in a free-range farm in which tail biting is absent. In total 214 pigs of different age categories were observed individually (sows, gilts, boars, and 6-month old pigs) or by group (6-month and 1-year old pigs) for their tail posture, tail motion and behaviour, using live observations and videos obtained by drone. Results showed that a fully curled tail occurred most during locomotion (P < 0.001); and an actively hanging tail occurred more during foraging (P < 0.001), excavation (P = 0.006), feeding (P = 0.017), receipt of agonistic behaviour (P = 0.036), and non-agonistic social interactions (P = 0.046). A fully curled tail (P < 0.001) and a half curled tail (P < 0.005) occurred least in the group of sows. Tail motion was infrequent (6.7% of observations), and involved mainly loosely wagging, which occurred more during locomotion (P = 0.006) and non-agonistic social interactions (P = 0.006). A higher temperature-humidity index increased the probability of half curled tails (P < 0.001) and loose wagging (P < 0.001), while reducing the probability of active (P < 0.001) and passive hanging tails (P = 0.013). These results provide insight into tail posture and tail motion in pigs under semi-natural conditions, showing especially that hanging tails are not primarily associated with tail biting, and that the use of tail postures for welfare assessment should be in consideration with the context in which the animals are kept.

INTRODUCTION: Electronic consultation (eConsultation) can precede, complete, or replace visits to the specialist. OBJECTIVE: To describe the profile of eConsultations issued from Primary Care (PC) to the Endocrinology Unit since their implementation in our hospital, to assess the response time and to evaluate changes in trends in relation to the COVID19 pandemic. A secondary objective is to evaluate the degree of satisfaction of PC specialists with this tool. MATERIAL AND METHODS: An observational retrospective study of Endocrinology eConsultations conducted from June 2019 to October 2020 analysing 2periods: pre-COVID and post-COVID. The degree of satisfaction of the Family and Community Medicine specialists was assessed by means of a questionnaire. RESULTS: 391 eConsultations were answered (69 pre-COVID and 322 post-COVID). The response time was less than 24h in 85% of them. A total of 35.3% were resolved without the need for visits or additional tests. Thyroid pathology was the most consulted. The incidence was significantly higher in the post-COVID period. The proportion of high resolution was significantly higher in the pre-COVID period. There were no differences in the rest of the parameters analysed in both periods. Thirty-nine point 2percent of PC specialists answered the survey. The degree of satisfaction of PC specialists was high. A total of 92.7% considered that the tool met their expectations and 90.5% were satisfied or very satisfied with its use. CONCLUSION: The COVID epidemic has driven the use of eConsultation in Endocrinology, which makes it possible to precede, complete or replace visits to the specialist, with a high degree of user satisfaction.

Evaluation of the Potential of Marine Algae Extracts as a Source of Functional Ingredients Using Zebrafish as Animal Model for Aquaculture.

Research on immunotherapeutic agents has become a focus for the treatment of fish diseases. The ability of algae to produce secondary metabolites of potential interest as immunotherapeutics has been documented. The present research intended to assess antiviral and antibacterial activities of macro- and microalgae extracts against viral and bacterial pathogens and explore their immunomodulatory potential using zebrafish (Danio rerio) larvae as a model organism. The cytotoxicity and antiviral activity of eight methanolic and ethanolic extracts from two macroalgae (Fucus vesiculosus, Ulva rigida) and two microalgae (Nannochloropsis gaditana, Chlorella sp.) were analyzed in established fish cell lines. Six extracts were selected to evaluate antibacterial activity by disk diffusion and growth inhibition assays. The three most promising extracts were characterized in terms of fatty acid composition, incorporated at 1% into a plant-based diet, and evaluated their effect on zebrafish immune response and intestinal morphology in a short-term feeding trial. All extracts exhibited in vitro antiviral activity against viral hemorrhagic septicemia and/or infectious pancreatic necrosis viruses. Methanolic extracts from F. vesiculosus and U. rigida were richer in saturated fatty acids and exhibited in vitro antibacterial action against several bacteria. Most promising results were obtained in vivo with F. vesiculosus methanol extract, which exerted an anti-inflammatory action when incorporated alone into diets and induced pro-inflammatory cytokine expression, when combined with the other extracts. Moreover, dietary inclusion of the extracts improved intestinal morphology. In summary, the results obtained in this study support the potential of algae as natural sources of bioactive compounds for the aquaculture industry.

Pheochromocytoma: A three-decade clinical experience in a multicenter study.

OBJECTIVE: To analyze the clinical and analytical features, diagnostic tests, therapies, and outcomes of pheochromocytoma (PCC). DESIGN AND METHODS: A multicenter retrospective study in surgically treated patients with PCC followed in 3 Spanish tertiary referral hospitals. RESULTS: A total of 106 patients (61 [57.5%] women, mean age 52.3 ±â€¯14.8 years) were evaluated. At diagnosis, PCC was symptomatic in 62% and sporadic in 83%. Patients with familial PCC were significantly younger than those with sporadic disease (40.8 ±â€¯14.2 years vs 54.5 ±â€¯13.9 years, p < .001). Familial PCCs were more frequently associated with MEN2A (n = 8). Levels of 24-h urinary fractionated metanephrines were positively related to tumor size. The maximum tumor diameter was 4.3 cm (3-6 cm); 27.7% of the patients had tumors ≥6 cm. Incidental PCCs were significantly smaller than symptomatic PCCs (3.4 cm [2.4-5.0 cm] vs 5.6 cm [4.0-7.0 cm], p < .001). Scintigraphy by ¹²³I-metaiodobenzylguanidine showed a high sensitivity (81.9%). Preoperative alpha blockade with phenoxybenzamine was used in 93.6% and doxazosin in the rest. Laparoscopic surgery was used in 2/3 of the patients, with a low conversion (1.9%) to open surgery. Perioperative complications appeared in approximately 20% of patients, mainly hypertensive crisis (9.4%). Recurrent disease appeared in 10%, and malignant PCC was uncommon (6.3%). CONCLUSIONS: PCCs surgically treated in Spain are usually large, symptomatic, and sporadic tumors diagnosed around the sixth decade of life. Hereditary PCC is usually associated with MEN2A. The main type of surgical technique used is laparoscopic surgery, and the prevalence of metastatic PCC is low.

Identificando puntos de mejoría en el manejo de la epilepsia en países en vías de desarrollo: experiencia de neurocooperación en Camerún / Identifying areas for improvement in epilepsy management in developing countries: An experience of neurocooperation in Cameroon

INTRODUCCIÓN: La epilepsia es una enfermedad prevalente en países en vías de desarrollo debido al mayor número de causas que pueden producirla, al menos duplicándose tanto incidencia como prevalencia en comparación con nuestro medio. Además, existe una gran estigmatización y los medios para su manejo son limitados. MATERIAL Y MÉTODOS: Estudio observacional descriptivo mediante la realización de un cuestionario a profesionales sanitarios de 3 hospitales de Camerún, interrogando sobre factores relacionados con el manejo de la epilepsia, en diciembre de 2016. Se presentan los datos como media o porcentaje. RESULTADOS: Participaron 38 profesionales sanitarios, de los cuales el 42,1% eran mujeres, con una edad media de 40,1 años (rango 22-62). Respecto a la causa de la enfermedad un 68,4% la considera psiquiátrica, 34,2% degenerativa, 28,9% hereditaria y 21,1% secundaria a una infección. En cuanto al manejo un 23,7% consideraba suficiente la anamnesis para llegar al diagnóstico. Solo un 60,5% consideraba la historia importante en el diagnóstico, 52,6% consideraba necesario un EEG, un 28,9% creía importantes las pruebas de laboratorio y un 13,2% la neuroimagen. Durante el embarazo solo un 36,8% considera importante asociar ácido fólico, solo el 65,8% cree que hay que mantener el tratamiento y solo un 39,5% creía recomendable la lactancia. Acerca del conocimiento de antiepilépticos, el número medio de fármacos conocido era de 2, siendo el más conocido el fenobarbital (81,6%) seguido de carbamacepina (55,3%) y ácido valproico (28,9%). CONCLUSIONES: La educación y la mejor información sobre la enfermedad, su diagnóstico y las opciones de manejo son necesarias en los profesionales sanitarios para optimizar el manejo y con ello la calidad de vida de los pacientes

INTRODUCTION: Epilepsy is especially prevalent in developing countries: incidence and prevalence rates are at least twice as high as in our setting. Epilepsy is also highly stigmatised, and few resources are available for its management. MATERIAL AND METHODS: We performed a descriptive observational study in December 2016, distributing a questionnaire on epilepsy management to healthcare professionals from 3 different hospitals in Cameroon. Data are presented as means or percentages. RESULTS: Thirty-eight healthcare providers participated in the survey; 42.1% were female and mean age was 40.1 years (range, 22-62). Regarding the causes of epilepsy, 68.4% considered it a psychiatric condition, 34.2% a degenerative disease, 28.9% a hereditary condition, and 21.1% secondary to infection. In terms of management, 23.7% considered that thorough clinical history is sufficient to establish a diagnosis. Only 60.5% considered the clinical interview to be important for diagnosis, 52.6% considered EEG to be necessary, and 28.9% considered laboratory analyses to be important. Only 13.2% mentioned neuroimaging. In the treatment of pregnant women, 36.8% recommended folic acid supplementation, 65.8% believed antiepileptic treatment should be maintained, and only 39.5% recommended breastfeeding. Concerning treatment, the participants knew a mean of 2 antiepileptic drugs: phenobarbital was the best known (81.6%), followed by carbamazepine (55.3%) and valproic acid (28.9%). CONCLUSIONS: There is a need among healthcare professionals for education and information on the disease, its diagnosis, and management options, in order to optimise management and consequently improve patients' quality of life

Feocromocitoma: experiencia clínica de tres décadas en un estudio multicéntrico / Pheochromocytoma: A three-decade clinical experience in a multicenter study

Objetivo Analizar las características clínicas y analíticas, las pruebas diagnósticas, los tratamientos y los resultados del feocromocitoma (FCC). Diseño y métodos Estudio multicéntrico retrospectivo en pacientes con FCC tratados quirúrgicamente y seguidos en 3 hospitales terciarios de referencia españoles. Resultados Se analizó a un total de 106 pacientes (61 [57,5%] mujeres, edad media 52,3 ± 14,8 años). En el diagnóstico, el FCC fue sintomático en el 62% de los casos y esporádico en el 83%. Los pacientes con FCC familiar eran significativamente más jóvenes que aquellos que presentaban la enfermedad esporádica (40,8 ± 14,2 años vs. 54,5 ± 13,9 años, p < 0,001). El FCC familiar se asociaba con mayor frecuencia a la MEN2A (n = 8). Los niveles de metanefrinas en orina de 24h se relacionaron positivamente con el tamaño del tumor. El diámetro tumoral máximo fue 4,3cm (3-6cm); el 27,8% de los pacientes tenían tumores ≥ 6cm. Los FCC incidentales eran significativamente más pequeños que los FCC sintomáticos (3,4cm [2,4-5,0cm] vs. 5,6cm [4,0-7,0cm], p < 0,001). La gammagrafía con 123I-metaiodobencilguanidina mostró una alta sensibilidad (81,9%). En el 93,6% de los casos se usó el bloqueo alfa preoperatorio con fenoxibenzamina y con doxazosina en los demás casos. En 2/3 de los pacientes se empleó la cirugía laparoscópica, con una baja tasa de conversión (1,9%) a cirugía abierta. Aproximadamente en el 20% de los pacientes aparecieron complicaciones perioperatorias, principalmente crisis hipertensivas (9,4%). La enfermedad recurrente apareció en el 10% de los casos y el FCC maligno fue raro (6,3%). Conclusiones Los FCC tratados quirúrgicamente en España suelen ser tumores grandes, sintomáticos y esporádicos diagnosticados alrededor de la sexta década de vida. El FCC hereditario está generalmente asociado con MEN2A. La cirugía laparoscópica es el tipo principal de técnica quirúrgica utilizada y la prevalencia del FCC metastásico es baja (AU)
