Tratamiento del quiste tirogloso mediante técnica de Koempel. Experiencia inicial / Treatment of thyroglossal cyst using Koempel’s technique: initial experience

Introducción: La intervención de Sistrunk es el gold-standard en el tratamiento del quiste tirogloso pese a su imprecisión en cuanto a la disección suprahioidea. Tras su descripción en 2014, las modificaciones introducidas por Koempel, han permitido un abordaje suprahioideo más reproducible. Presentamos nuestra experiencia inicial con esta técnica. Métodos: Estudio retrospectivo de los pacientes con quiste tirogloso intervenidos mediante técnica de Koempel en nuestro centro en el periodo 2021-2022, recogiéndose datos demográficos, clínicos e histológicos. Resultados. Durante el periodo de estudio se intervinieron 5 pacientes (3 mujeres/2 varones), con una mediana de edad y peso de 5 años (2-6) y 16 kg (14-25) respectivamente. Todos los casos habían sufrido infecciones previas presentando fistulización cutánea el 60%. En 2 de los pacientes se indicó la cirugía por recidiva tras intervención de Sistrunk. La mediana del tiempo quirúrgico fue de 77minutos (57-110) identificándose el plano del músculo geniogloso en los 5 pacientes. No hubo complicaciones inmediatas y el diagnóstico de quiste tirogloso se confirmó histológicamente en todos los casos. Uno de los pacientes del grupo con recidiva previa, presentó recidiva tras la intervención, siendo esta subclínica y diagnosticada incidentalmente tras ecografía de control. El resto de los pacientes no presentó ninguna recurrencia tras un seguimiento mediana de 8 meses (1-12). Conclusiones: La técnica de Koempel permite un abordaje seguro y reproducible del segmento suprahioideo siendo una opción atractiva en casos complicados por infección o recidiva previa.(AU)

Introduction: In spite of being inaccurate in terms of suprahyoid dissection, Sistrunk’s procedure is the gold-standard technique in the treatment of thyroglossal cyst. Since it was first described in 2014, the modifications introduced by Koempel have allowed for a more reproducible suprahyoid approach. We present our initial experience with this technique.Methods: A retrospective study of patients with thyroglossal cyst undergoing Koempel’s technique in our institution from 2021 to 2022 was carried out. Demographic, clinical, and histological data was collected. Results. In the study period, 5 patients –3 girls and 2 boys– underwent surgery. Median age and weight were 5 years (2-6) and 16 kg (14-25), respectively. All patients had suffered from previous infections, with 60% having cutaneous fistulization. In 2 patients, surgery was indicated following Sistrunk’s procedure as a result of recurrence. Median operating time was 77 minutes (57-110), with the genioglossal muscle plane being identified in the 5 patients. No immediate complications were recorded, and diagnosis of thyroglossal cyst was histologically confirmed in all cases. One of the formerly recurrent patients had recurrence following surgery, but it was subclinical and incidentally diagnosed at control ultrasonography. The remaining patients had no recurrences after a median 8-month (1-12) follow-up period. Conclusions: Koempel’s technique allows for a safe and reproducible approach of the suprahyoid segment. It is an attractive option in complicated cases as a result of previous infection or recurrence.(AU)

Urgent laparoscopic cholecystectomy as a result of acute calculous cholecystitis in Pediatrics. / Colecistectomía laparoscópica urgente por colecistitis aguda litiásica en Pediatría.

INTRODUCTION: In spite of the increase in the prevalence of cholelithiasis in the last decades, no recommendations regarding the best treatment of acute calculous cholecystitis (AC) in Pediatrics have been developed. CLINICAL CASE: 4-year-old, 20kg male patient with no significant history referred to our institution as a result of abdominal sepsis. The blood count showed leukocytosis, with normal hemoglobin and bilirubin levels, and a normal liver function. The abdominal ultrasonography revealed cholelithiasis, gallbladder hydrops, and an inflammatory process compatible with appendicular plastron. In the diagnostic laparoscopy, the appendix was macroscopically normal, and acute cholecystitis was observed. Given the patient's situation, and in cooperation with the General Surgery Department, laparoscopic cholecystectomy was carried out. The patient recovered uneventfully on hospitalization day 5 under piperacillin-tazobactam treatment. DISCUSSION: There are no recommendations regarding AC treatment in children. In septic patients, cooperation between general and pediatric surgeons allows urgent cholecystectomy to be considered as a safe option.

INTRODUCCION: Pese al aumento en la prevalencia de colelitiasis durante las últimas décadas, no se han desarrollado recomendaciones sobre el mejor tratamiento de la colecistitis aguda litiásica (CA) en Pediatría. CASO CLINICO: Paciente varón de 4 años y 20 kg de peso sin antecedentes de interés, que acude derivado por sepsis de origen abdominal. Analíticamente destaca leucocitosis con hemoglobina, función hepática y bilirrubina normales. La ecografía abdominal muestra colelitiasis, hidrops vesicular y proceso inflamatorio compatible con plastrón apendicular. En laparoscopia diagnóstica se observa apéndice macroscópicamente normal y colecistitis aguda. Ante la situación del paciente se realiza, conjuntamente con Cirugía General, colecistectomía laparoscópica. El paciente se recupera sin incidencias tras 5 días de ingreso bajo cobertura con piperacilina-tazobactam. COMENTARIOS: No existen recomendaciones sobre el tratamiento de la CA en niños. En los pacientes sépticos, la colaboración entre cirujanos pediátricos y cirujanos generales permite contemplar la colecistectomía urgente como una opción segura.

Intraventricular hemorrhage as complication after spinal surgery. Case report.

Remote intracranial hemorrhage (ICH) is a rare but dreaded complication after spinal surgery. The physiopathology of this phenomenon is closely related to a loss of cerebrospinal fluid (CSF) after an incidental durotomy during spine surgery. The most common remote ICH location is cerebellar, but few articles report intraventricular hemorrhage. Its clinic is associated with cerebral hypotension due to decreased CSF, mainly headache, dysarthria, hemiparesis, an impaired level of awareness and seizures. The diagnosis of remote ICH after a non-cranial surgery can be a challenge to anesthesiologists, this pathology should be suspected face an immediate neurological deterioration after anesthetic awakening. Non-specific symptoms make it difficult to identify the origin of intracranial hemorrhagic from other differential diagnoses. We present a patient with an impaired level of awareness and seizures who suffered a hemorrhage in the right ventricle with cerebral and cerebellar edema in the immediate postoperative period after spinal surgery.

Hemorragia intraventricular como complicación tras una cirugía espinal. Caso clínico / Intraventricular hemorrhage as complication after spinal surgery. Case report

La hemorragia intracraneal (HIC) remota es una rara pero temida complicación tras la cirugía espinal. La fisiopatología de este fenómeno se relaciona estrechamente con la pérdida de líquido cefalorraquídeo (LCR) tras una lesión dural incidental durante la cirugía espinal. La localización de la HIC remota más frecuente es la cerebelar, existiendo pocos casos publicados de hemorragia intraventricular. Su clínica está asociada a la hipotensión cerebral por disminución de LCR, destacando la cefalea, la disartria, la hemiparesia, el deterioro del nivel de conciencia y las convulsiones.El diagnóstico de una HIC remota tras una cirugía no craneal puede ser un reto para los anestesiólogos; esta enfermedad debería sospecharse ante un deterioro neurológico inmediato al despertar anestésico. La sintomatología inespecífica dificultará identificar el origen hemorrágico intracraneal frente a otros diagnósticos diferenciales.Exponemos el caso de un paciente con disminución del nivel de conciencia y convulsión que presentó una hemorragia intraventricular derecha con edema cerebral y cerebeloso en el postoperatorio inmediato de una cirugía espinal.(AU)

Bilateral serous retinal detachment in a patient with atypical presentation of preeclampsia due to HELLP syndrome.

Exudative retinal detachment (ERD) is a rare complication that occurring in 1% of patients with preeclampsia, its incidence is increased when it is associated with HELLP syndrome. Preeclampsia is defined by the development of arterial hypertension and proteinuira occurs after 20 weeks of gestation until postpartum. HELLP syndrome (low platelets, hemolysis and elevated liver enzymes) is a severe form of preeclampsia. ERD in preeclampsia is related to choroidal ischaemia, in the vast majority of the cases associated with hypertensive retinopathy. However, it has been proposed that the combination of hypertension with a microangiopathic hemolysis, hipercoagulability and hypoalbuminemia are the main factors contributing to the development of ERD. Its treatment includes a rapid resolution of labor to reverse ocular manifestations and prevent visual sequels. We describe the case of a pregnant woman with atypical preeclampsia who, in the postpartum of a cesarean, presented an ERD concomitantly with a HELLP syndrome.

Desprendimiento de retina exudativo bilateral en paciente con presentación atípica de preeclampsia por síndrome de HELLP / Bilateral serous retinal detachment in a patient with atypical presentation of preeclampsia due to HELLP syndrome

El desprendimiento de retina exudativo (DRE) es una rara complicación que afecta al 1% de preeclampsias, aumentando su incidencia cuando se asocia con síndrome de HELLP.La preeclampsia se define por el inicio de hipertensión arterial y proteinuria tras la 20.ª semana de gestación hasta el posparto. EL síndrome de HELLP (trombocitopenia, hemólisis y elevación de enzimas hepáticas) constituye una forma severa de preeclampsia.El DRE en la preeclampsia está relacionado con isquemia coroidal, en la mayoría de los casos asociado a retinopatía hipertensiva. Sin embargo, se ha propuesto que la combinación de hipertensión junto a microangiopatía hemolítica, hipercoagulabilidad e hipoalbuminemia son los principales factores implicados en el DRE.Su tratamiento incluye una resolución rápida del parto para revertir las manifestaciones oculares y prevenir secuelas visuales.Se describe el caso de una gestante con preeclampsia atípica que, en el posparto de una cesárea, presentó un DRE concomitante con un síndrome de HELLP.(AU)

Direct oral anticoagulants for the treatment and prevention of venous thromboembolism in patients with cancer: current evidence

Venous thromboembolic disease (VTED) is a common and clinically important complication in patients with cancer, contributing to its mortality and morbidity. Direct oral anticoagulant agents (DOACs), including direct thrombin inhibitors and direct factor Xa inhibitors, are as effective as vitamin K antagonists for the treatment of VTED and are associated with less frequent and severe bleeding. They have advantages over low-molecular-weight heparin, but comparative long-term efficacy and safety data are lacking for these compounds. Recent randomized clinical trials suggest a role for DOACs in the treatment of VTED in patients with cancer. This review will discuss the existing evidence and future perspectives on the role of DOACs in the treatment of VTE based on the current evidence about their overall efficacy and safety and the limited information in patients with cancer; in addition, we will briefly review their pharmacokinetic properties with special reference to potential interactions (AU)

Occurrence of mycotoxins in talkan: a cereal-based food traditional for Turkic population.

The consumption of cereal contaminated with mycotoxins poses a serious health risk for humans and animals. The present work aims to evaluate the presence of mycotoxins in talkan, a cereal-based food commonly consumed by the Turkic population. The presence of mycotoxins was investigated in a total of 50 samples obtained from Kazakhstan. After a preliminary screening using various ELISA kits, mycotoxins were confirmed and quantified by HPLC-MS/MS method. More than 28% of the samples were positive for at least one mycotoxin. The calculated probably daily intake for adults and children was 20% above the tolerable daily intake for aflatoxin B1 and deoxynivalenol, while it was above 100% for zearalenone, indicating a high risk for the Kazakh population. A total of 12 samples exhibited concentrations above the European maximum level for ochratoxin A, zearalenone and deoxynivalenol, however, these values were within the limits established by the Russia-Kazakhstan-Belarus Customs Union (TR CU 015/2011).
