ABSTRACT
Resumen Antecedes: El síndrome de Klippel-Trenaunay (KTS) es un síndrome de malformación vascular que comprende una afectación variable de capilares cutáneos, venas y linfáticos con hipertrofia de tejidos blandos y huesos de la extremidad afectada. Durante el embarazo estas malformaciones se incrementan, con afectación pélvica e intraabdominal. Caso clínico: Paciente de 15 años, primigesta, con síndrome Klippel-Trenaunay diagnosticado al nacimiento, con embarazo a término, referida por iniciar con trabajo de parto para finalización del embarazo en un hospital de tercer nivel. No cuenta con control obstétrico, estudios prenatales ni ultrasonidos obstétricos. Se realiza una ecografía pélvica en donde se descartóla presencia de varices pélvicas y un doppler que evidenció un sistema venoso conservado. Se realiza terminación del embarazo vía abdominal obteniendo un recién nacido vivo masculino, peso de 3045 gramos, APGAR 9 y 9 al minuto y a los 5 minutos. Resultados: El embarazo en pacientes con síndrome de Klippel-Trenaunay tiene alto riesgo de tromboembolismo y complicaciones hemorrágicas. La valoración debe ser por un equipo multidisciplinario capacitado para anticiparse a las potenciales complicaciones. Limitaciones del estudio o implicaciones: La principal limitación es la baja incidencia de esta patología. Se puede concluir que el diagnostico de SKT no es indicación de interrupción del embarazo. El éxito del manejo de estas pacientes requiere la participación de un equipo multidisciplinario. Originalidad o valor: Este caso clínico es de primordial relevancia ya que en la bibliografía internacional están reportados menos de 100 casos de embarazos complicados con este síndrome.
Abstract: Background: Klippel-Trenaunay syndrome (KTS) Klippel- Trenaunay syndrome (KTS) is a vascular malformation síndrome that includes variable involvement of skin capillaries, veins and lymphatics with hypertrophy of soft tissues and bones of the affected limb. During pregnancy, these malformations increase, with pelvic and intra-abdominal involvement. Clinical case: 15-year-old patient, gravida 0, with Klippel- Trenaunay syndrome diagnosed at birth, with full-term pregnancy, referred for initiating labor for resolution of pregnancy in a third level hospital. Without obstetric control, without prenatal studies or obstetric ultrasounds. A pelvic ultrasound was performed, which ruled out the presence of pelvic varices and a Doppler that showed a preserved venous system. The pregnancy was terminated by abdominal route, obtaining a male newborn, weighting 3045 grams, APGAR 9 and 9 after 1 and 5 minutes. Results: Pregnancy in patients with Klippel-Trenaunay síndrome has a high risk of thromboembolism and bleeding complications. They should be evaluated by a trained multidisciplinary team to anticipate possible complications. Study limitations or implications: The main limitation is the low incidence of this pathology. It can be concluded thatthe diagnosis of SKT is not an indication for termination of pregnancy. Successful management of these patients requires the participation of a multidisciplinary team. Originality or value: This clinical case is of primary relevance since fewer than 100 cases of complicated pregnancies with this syndrome are reported in the international literature.
ABSTRACT
Acute leukemia (AL) is an important cause of morbidity and mortality in children, and neurological manifestations (NM) are frequent. The objective of this study was to analyze neurological manifestations in children with acute leukemia from cases attended in the last five years at the Centro Médico Nacional "20 de Noviembre". METHODS: Conducting a retrospective and analytical study from 1 January 2015 to 31 December 2020 in children with AL classified according to sex, age range and AL type. Participants were grouped according the presence of NM. RESULTS: We analyzed 607 patients: 54.85% boys and 44.14% girls, with a mean age of 7.27 ± 4.54 years. When comparing groups, the NM group was significantly older (p = 0.01), and the highest prevalence was between 6 and 12 years old. ALL was predominant over the other lineages (p ≤ 0.01). The most frequent NM was CNS infiltration, seizures, headache and neuropathy. Death outcomes occurred in 18.7% of children with AML, 11.8% with ALL and 50% with MPAL (p ≤ 0.002). The NM group was associated with higher mortality during a follow-up time of 77.9 ± 49 months (44.4% vs. 8.9% deaths, NM vs. non-NM, respectively; OR = 3.3; 95% CI 2.4 to 4.6; p ≤ 0.0001). CONCLUSIONS: ALL was the most prevalent leukemia type. CNS infiltration, seizures, headache, neuropathy and PRES were the most frequent symptoms in the NM group. NM was associated with a higher mortality rate.
ABSTRACT
COVID-19 has affected millions of children and, while it was previously considered as a respiratory disease, neurologic involvement has also been documented. The objective of this study was to identify the neurological manifestations (NMs) and the outcomes of children with COVID-19 who attended the National Medical Center "20 de Noviembre". METHODS: A retrospective cohort study of children hospitalized for COVID-19 from April 2020 to March 2021 was conducted. Clinical-demographic data were registered. Neurologic manifestations were defined as any clinical neurological expression of the central and/or peripheral nervous system that occurred during admission or hospitalization. RESULTS: In total, 46 children with a confirmed COVID-19 result, 26 (56.5%) boys and 20 (43.5%) girls with a median age of 8.9 ± 4.6 years, constituted the study population. Half of the children showed some NMs, and this group of patients concomitantly showed acute lymphoblastic leukemia (ALL, 56%), obesity (17.3%), or acute myeloblastic leukemia (AML, 4.3%). The most frequently described NMs were headache (13, 56%), encephalopathy (10, 43.47%), and epilepsy (4, 17.39%). The mortality rate in children with NMs was 21.7% and they had a higher mortality rate when compared to those without NM p ≤ 0.025. CONCLUSIONS: NMs occurred predominantly in male children aged 6 to 12 years; ALL was the most frequent comorbidity. Headache prevailed and hypoxemia, hypocalcemia, elevated ferritin, and C-reactive protein were associated with NM. Finally, NMs were a risk factor for mortality.
