Thoracoscopic pneumonectomy in a 4 year-old-child with destroyed lung following viral pneumonia. / Tiroidectomía transoral endoscópica con abordaje vestibular (TOETVA): una nueva opción para el tratamiento de pacientes pediátricos.

Pediatric pneumonectomies are exceptional nowadays, being reserved for cases with destroyed lungs with frequent exacerbations and reinfections and only two cases of thoracoscopic pneumonectomy have been previously published. We present the case of a 4-year-old patient with no relevant history who developed complete atelectasis of the left lung (LL) after influenza A pneumonia, followed by secondary recurrent infections. A year later a diagnostic bronchoscopy without alterations was performed. A complete loss of volume and hypoperfusion of the LL (right lung perfusion 95%, LL perfusion: 5%) with bronchiectasis and hyperinsufflation and herniation of the right lung into the left hemithorax was observed in a pulmonary perfusion SPECT-CT. After unsuccessful conservative management and recurrent infections a pneumonectomy was indicated. The pneumonectomy was performed through a five-port thoracoscopy. The dissection of the hilum was made using hook electrocautery and sealing device. The left main bronchus was sectioned with an endostapler. There were no intraoperative complications. An endothoracic drain was removed the first postoperative day. The patient was discharged on the fourth postoperative day. The patient has not presented any complications 10 months after surgery. Although pneumonectomy is an exceptional surgery in children, it can be performed by minimally invasive surgery with success and safety in centers with extensive experience in pediatric thoracoscopic surgery.

Hoy en día, las neumonectomías pediátricas son algo excepcional. El procedimiento se reserva para aquellos casos en los que los pulmones están destruidos y presentan exacerbaciones y reinfecciones frecuentes, con tan solo dos casos de neumonectomía toracoscópica publicados hasta la fecha. Presentamos el caso de un paciente de 4 años sin antecedentes de interés que desarrolló atelectasia completa del pulmón izquierdo (PI) tras neumonía por gripe A, seguido de infecciones secundarias recurrentes. Un año después, se le practicó broncoscopia diagnóstica, sin que esta mostrara alteraciones significativas. Tras realizársele un SPECT-CT de perfusión pulmonar, se evidenció pérdida completa de volumen e hipoperfusión del PI (perfusión del pulmón derecho: 95%; perfusión del pulmón izquierdo: 5%), con bronquiectasia e hiperinsuflación y herniación del pulmón derecho hacia el hemitórax izquierdo. Tras fracasar el manejo conservador y registrarse infecciones recurrentes, se estableció la indicación de neumonectomía. La neumonectomía se llevó a cabo mediante toracoscopia por cinco puertos. La disección del hilio se realizó mediante gancho de electrocoagulación y dispositivo de sellado. El bronquio principal izquierdo se seccionó con endograpadora. No se registraron complicaciones intraoperatorias. El drenaje endotorácico se retiró al día siguiente de la intervención, mientras que el paciente fue dado de alta a los cuatro días, sin que haya presentado complicaciones transcurridos 10 meses desde la cirugía. Aunque la neumonectomía es una intervención excepcional en niños, puede llevarse a cabo de manera exitosa y segura por cirugía mínimamente invasiva en centros con amplia experiencia en cirugía toracoscópica pediátrica.

[Cognitive neurorehabilitation: the foundations and applications of neurologic music therapy]. / Neurorrehabilitacion cognitiva: fundamentos y aplicaciones de la musicoterapia neurologica.

INTRODUCTION: Music is the result of a perception in the brain involving a number of cortical and subcortical areas in both brain hemispheres. Increased knowledge about brain plasticity and the numerous neuroimaging studies conducted in recent years have made it possible to further our understanding of the processing of musical stimuli in the brain. This has led to an interest in analysing and studying its application in the non-invasive treatment of certain dysfunctions or diseases with the aim of helping to achieve an improved quality of life. AIM: To outline the foundations and applications of the musical techniques that are used in cognitive neurorehabilitation. DEVELOPMENT: Following an initial summary of the processing of musical stimuli in the brain, the study goes on to explain the foundations of different techniques, as defined by neurologic music therapy, that are used efficaciously in cognitive neurorehabilitation. Sounds, which are the raw material of music, maintain a temporality and a sequencing that are a useful aid in the formation of temporal patterns of the cognitive functions, and constitute an assembly or framework that facilitates the learning of sequential information processing, such as memory. CONCLUSIONS: The techniques used in neurologic music therapy, which in recent years are being applied for cognitive neurorehabilitation, are not invasive and offer promising results that, together with further research, should be taken into account to be implemented alongside the conventional therapies of cognitive neurorehabilitation and stimulation.

TITLE: Neurorrehabilitacion cognitiva: fundamentos y aplicaciones de la musicoterapia neurologica.Introduccion. El conocimiento de la plasticidad cerebral y los numerosos estudios con neuroimagenes de los ultimos años han permitido un avance en la comprension del proceso cerebral de los estimulos musicales. Ello ha propiciado el interes para analizar y estudiar su aplicacion en el tratamiento no invasivo de determinadas disfunciones o enfermedades con el fin de contribuir a una mejora de la calidad de vida. Objetivo. Exponer los fundamentos y aplicaciones de las tecnicas musicales que se utilizan para la neurorrehabilitacion cognitiva. Desarrollo. A partir de un resumen inicial del proceso cerebral de los estimulos musicales, se exponen los fundamentos de diversas tecnicas, tal como define la musicoterapia neurologica, que se utilizan de forma eficaz en la neurorrehabilitacion cognitiva. Los sonidos, que constituyen la materia prima de la musica, mantienen una temporalidad y una secuenciacion que son utiles para ayudar a la formacion de patrones temporales de las funciones cognitivas y conforman un ensamblaje o armazon que facilita el aprendizaje de los procesos secuenciales de informacion, como por ejemplo, la memoria. Conclusiones. Las tecnicas usadas por la musicoterapia neurologica, que en los ultimos años se aplican en la neurorrehabilitacion cognitiva, no son invasivas y aportan resultados esperanzadores; con una mayor investigacion, deberian considerarse para su implantacion junto a las terapias convencionales de estimulacion y neurorrehabilitacion cognitiva.

[Utility of radioguided surgery in splenosis]. / Utilidad de la cirugía radioguiada en la esplenosis.

Splenosis is a common finding after traumatic rupture of the spleen or therapeutic splenectomy, defined as a heterotopic autotransplantation of the spleen in peritoneal cavity and surface. In splenectomized patients due to hematologic disease, splenosis can lead to disease recurrence. We present a case of splenosis in a patient with idiopathic thrombocytopenic purpura who relapsed after splenectomy. For its localization, conventional imaging and scintigraphy with (99m)Tc-denatured red cells was performed, and at least five splenic foci were observed. Given the difficult intraoperative localization of these nodules, radioguided surgery was performed, with excellent localization and removal of all known nodules and multiple peritoneal implants of millimeter size that were not previously observed. We conclude that radioguided surgery is an excellent tool for locating foci of peritoneal splenosis, which have difficult access, thus avoiding early recurrence of the disease.

[Laparoscopic cholecystectomy: what we can learn about]. / Colecistectomía laparoscópica en niños y adultos: lo que podemos aprender.

BACKGROUND: Laparoscopic cholecystectomy (LC) is a very usual procedure within adult population, but not as frequent in childhood. The aim of this study was to assess the outcome of LC in children compared with those performed in adulthood. MATERIALS AND METHODS: We reviewed 39 consecutive patients who underwent LC between 2003 and 2013 at our Department and a similar sample of patients from 18 to 40 years of age from the General Surgery Department. RESULTS: 39 children and 40 adults fulfilled criteria to be included in the study. The most frequent indication was cholelithiasis in both groups. The mean operating time was significantly higher among children (127 min, adults 71 min, p < 0.01) but we didn't find differences neither in conversion nor in complication rates (children 5% and 7.7%, adults 2.5% and 15% respectively). In regard to preoperative factors, only male gender was correlated to a higher complication rate (p 0.037). On the other hand we found out that, in absence of complications, both the average length of stay (children 2.1 days, adults 0.5 days) and mean time to first feeding (children 21 hours, adults 8 hours) were significantly higher among children (p < 0.01). CONCLUSIONS: 1) LC in childhood is a safe procedure that does not imply more morbidity than the same intervention in adults, even though a more prolonged operating time. 2) We believe that our longer hospital stay is due to certain lack of confidence with the technique and, in the future, the trend should be bent on encouraging a shorter time to first feeding and an earlier discharge.

Papel de la laparoscopia en prematuros con sospecha de enterocolitis necrotizante / Role of laparoscopy in premature infants with suspicion of necrotizing enterocolitis

Introducción. La indicación quirúrgica en la enterocolitis necrotizante(ECN) puede ser difícil en ausencia de neumoperitoneo o peritonitis secundaria. Proponemos la laparoscopia para realizar un diagnóstico precoz de perforaciones o necrosis intestinal y evitar laparotomías “en blanco”. Material y métodos. Se planteó un protocolo diagnóstico terapéutico que incluyera la laparoscopia en los casos de ECN de indicación quirúrgica incierta. Posteriormente se realizó un estudio prospectivo de los 7 pacientes en los que se realizó laparoscopia, analizando efectos fisiopatológicos en el prematuro, dificultades técnicas del procedimiento, congruencia diagnóstica y evolución postoperatoria. Resultados. La edad gestacional media al nacimiento fue de 27semanas (rango 25 a 31) con un peso medio de 1,147 kg (rango 0,900 a1,600). Se colocaron dos trócares orientados según la focalidad de la exploración o la radiología, aplicando un neumoperitoneo de 6-10 mm Hg durante una media de 17 min. La laparoscopia evitó la laparotomía en un paciente, que evolucionó bien tras lavado y drenaje; y magnificólas lesiones en otro paciente que, tras la laparotomía, no precisó derivación intestinal. En el resto de los casos la laparoscopia permitió una minilaparotomía orientada a las lesiones y derivación intestinal. No se produjo ninguna complicación quirúrgica atribuible al procedimiento, que fue bien tolerado en todos los casos. Conclusiones. La laparoscopia puede ser una herramienta útil para valoración de las lesiones de ECN en los casos de indicación quirúrgica incierta. En nuestra experiencia es bien tolerada en el neonato de bajo peso, permitiendo orientar el tratamiento quirúrgico e, incluso, evitarla laparotomía (AU)

Introduction. The indication of surgery in necrotizing enterocolitis(NEC) can be difficult in the absence of pneumoperitoneum or peritonitis. We propose laparoscopy for early diagnosis of intestinal perforation or necrosis in order to avoid unneccessary laparotomies. Material and methods. A new protocol was proposed which included diagnostic and therapeutic laparoscopy in cases of uncertain surgical ECN indication. Subsequently, a prospective study of the 7 patients who underwent laparoscopy was performed, analyzing pathophysiological effects in the premature, technical difficulties of the procedure, and postoperative diagnostic consistency. Results. The mean gestational age at birth was 27 weeks (range 25 to31) with an average weight of 1.147 kg (range 0.900 to 1.600) two trocars were placed as the focal oriented scanning or radiography, using a pneumoperitoneum6-10 mmHg for an average of 17 min. Laparoscopy avoided laparotomy in a patient who did well after washing and drainage and magnified lesions in one patient who did not require laparotomy after intestinal bypass. In other cases, laparoscopy was followed by minilaparotomy oriented to the lesions and stoma formation. There were no surgical complications attributable to the procedure, which was well tolerated in all cases. Conclusions. Laparoscopy can be a useful tool for evaluation of lesions of NEC in cases of uncertain surgical indications. In our experience ,it is well tolerated in neonates of low weight, allowing oriented minilaparotomies or even to avoid laparotomy (AU)

Central retinal vascular obstruction secondary to melanocytoma of the optic disc.

A 35-year-old black man developed abrupt visual loss in his left eye. Ophthalmic examination revealed a deeply pigmented mass obscuring the optic disc, hemorrhagic retinopathy, and signs of central retinal vascular obstruction. Fluorescein angiography disclosed sluggish filling of the retinal blood vessels; ultrasonography disclosed an acoustically solid mass in the optic nerve head. Cytopathologic findings of a fine needle aspiration biopsy specimen demonstrated probable benign tumor cells, but melanoma could not be excluded. Histopathologic findings in the enucleated eye revealed a large, necrotic melanocytoma of the optic disc and hemorrhagic necrosis of the retina secondary to obstruction of the central retinal artery and vein. Melanocytoma of the optic nerve can undergo spontaneous necrosis and induce central retinal vascular obstruction. Abrupt visual loss in a patient with a melanocytoma does not necessarily imply malignant transformation.

[Effect of fasting and maintenance solutions on perioperative blood glucose in children]. / Influencia del ayuno y soluciones de mantenimiento sobre la glucemia perioperatoria en el paciente pediátrico.

The effects of fasting on preoperative glycemic levels and the influence of different intravenous solutions on postoperative sugar levels are discussed. Sugar levels were determined in 90 children, randomly placed in three groups, (according to the solution they were administered-A: Ringer-lactate, B: glucose at 5%, C: mixed-2 x 1) at the time they entered the hospital, after fasting previous to the anesthetic induction, and in the immediate postoperative period. In 14.4% of the cases hypoglycemia was found during the anesthetic induction, increasing as the fasting period was prolonged. The postoperative hyperglycemia seen in Group B was important, the other groups showed no significant changes. We recommend that the fasting period be no longer than 12 hours and to immediately start intravenous restitution if this period is extended further. Also, only Ringer's lactate solution or a 2 to 1 mixture is recommended to be used during surgery in order to avoid preoperative hypoglycemia and postoperative hyperglycemia. Glycemia; fasting; perioperative solutions.

Treatment of total retinal detachment in morning glory syndrome.

A 14-year-old girl had headaches and sudden loss of vision as a result of total retinal detachment in association with the morning glory optic nerve anomaly. Metrizamide cisternography with contrast dye introduced into the subarachnoid space disclosed migration of metrizamide with radiographic enhancement in the subretinal space. The demonstration of an abnormal communication between the subarachnoid and subretinal spaces suggested that the subretinal fluid is of cranial origin. The patient underwent surgical removal of a window of dura from the optic nerve sheath. This resulted in retinal reattachment and improvement of visual acuity to 20/200. The retina was still attached after a 15-month follow-up period.

Retinal detachment following branch vein occlusion: case report.

A case is presented of a patient with the unusual situation of a rhegmatogenous retinal detachment from an old branch vein occlusion, who in addition, had a macular hole. The detachment was cured by a scleral buckle involving the peripheral hole only.

Incidence of cystoid macular edema after different cataract operations.

With the development of new cataract surgical techniques, the question has arisen of whether the incidence of cystoid macular edema has actually increased, decreased or remained unchanged. A control study to determine the incidence of persistent cystoid edema following extracapsular cataract extraction and artificial lens implantation versus a similar age-group is being done in Miami using the traditional intracapsular cataract technique. The incidence of cystoid edema among patients submitted for phacoemulsification with or without lens implantation are also discussed.
