Single versus Double Drainage for Immediate Two-Stage Implant-Based Breast Reconstruction: A Propensity Score-Matched Analysis.

BACKGROUND: Reports evaluating plastic surgeons' practices indicate there are conflicting trends regarding the use of one or two drains for implant-based breast reconstruction (IBBR). Our study aimed to perform a matched cohort analysis to examine the postoperative outcomes and complications of immediate IBBR with tissue expander (TE) using two drains versus a single drain. METHODS: A propensity score-matched analysis (nearest neighbor, 1:1 matching) of immediate reconstructions using two versus one drain was conducted. Female patients undergoing immediate two-stage IBBR with TEs between January 2011 and May 2021 were included. The covariables were as follows: BMI, mastectomy weight, lymph node surgery, TE surface, plane of reconstruction, use of acellular dermal matrix products, fluorescence imaging use, and intraoperative TE volume. RESULTS: After matching using propensity scores, 192 reconstructions were included in the final analysis: 96 in each group. The rate of 30-day complications and overall complications during the first phase of IBBR were comparable between groups. The time for drain removal, time to initiate and finalize expansions, and time for TE-to-implant exchange were comparable between groups. Diabetes (OR 3.74, p = 0.025) and an increased estimated blood loss (OR 1.004, p = 0.01) were the only independent predictors for seroma formation. CONCLUSION: In this matched cohort analysis evaluating the role of one versus two drains for two-stage IBBR, we found a comparable rate of complications and surgical outcomes between the two cohorts. Using two drains for immediate IBBR needs to be tailored depending on intraoperative findings. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Subpectoral versus prepectoral two-stage breast reconstruction: A propensity score-matched analysis of 30-day morbidity and long-term outcomes.

BACKGROUND: Approximately 80% of patients undergoing total mastectomy in the US opt for implant-based breast reconstruction (IBBR). A two-stage reconstruction with tissue expander (TE) remains the most common technique. Since the implementation of ADMs, a prepectoral approach has gained popularity and is becoming the standard of care. Herein, we compared the surgical and postoperative outcomes of prepectoral versus subpectoral two-stage IBBR. METHODS: A retrospective chart review was performed between January 2011 and December 2020. We included female patients undergoing immediate two-stage IBBR. The primary outcomes of this study were to compare the 30-day morbidity and the overall rate of complications during the first and second stages of reconstruction, and to compare the time to initiate postmastectomy radiotherapy (PMRT). Propensity score matching was implemented. RESULTS: After matching, 154 reconstructions were analyzed, 77 in each group. The two matched groups exhibited comparable (p > 0.05) characteristics for all analyzed demographic and intraoperative independent variables. Reconstructions in the prepectoral group had a shortened median time for drain removal (13-days vs. 15-days, p = 0.001). The intraoperative expansion volumes were higher in the prepectoral group (300 ml versus 200 ml, p = 0.025). The 30-day morbidity and first- and second-stage complication rates were not significantly different between groups. The time to start postmastectomy radiation therapy (PMRT) was not significantly different between groups (134-days versus 126.5-days, p = 0.58). CONCLUSION: Prepectoral and subpectoral TE placement had comparable complication rates during the first and second stages of IBBR. Timing for TE-to-Implant exchange and initiation of PMRT were comparable between the two approaches.

Sentinel lymph node biopsy and immediate two-stage implant-based breast reconstruction: A propensity score-matched analysis.

BACKGROUND: There are important differences between patients requiring sentinel lymph node biopsy (SLNB) and those who do not require axillary surgery at the time of breast reconstruction. We aimed to perform a propensity score-matched analysis to evaluate the impact of SLNB at the time of immediate implant-based breast reconstruction (IBBR) with tissue expanders compared with IBBR alone. METHODS: Consecutive female patients undergoing total mastectomy and immediate two-stage IBBR between January 2011 and May 2021 were included. A 1:1 nearest-neighbor matching method without replacement was implemented with a caliper width of 0.01. Patients were matched for age, diabetes, hypertension, hyperlipidemia, premastectomy radiotherapy, neoadjuvant chemotherapy, the plane of prosthesis placement, mastectomy specimen weight, number of drains, and radiation of the expander. RESULTS: We included 320 two-stage immediate IBBRs after propensity score matching, 160 reconstructions per group. Relevant surgical variables were comparable between groups. A higher rate of 30-day seroma formation was reported in immediate reconstructions that had SLNB at the time of mastectomy compared with reconstructions that did not have axillary surgery (16.3% versus 8.1%, p = 0.039). The time to complete outpatient expansions and time for expander-to-implant exchange were comparable between patients who underwent IBBRs with SLNB and those who did not. CONCLUSION: SLNB performed at the time of mastectomy and IBBR with tissue expander increased the risk of seroma formation compared with reconstructions that did not have axillary surgery. The rate of infection, hematoma, and unplanned procedures to manage complications did not differ between groups.

Integridad cognitiva y motora-sensorial en un niño con esquizencefalia de labio abierto unilateral derecho: reporte de caso / Cognitive and motor-sensorial integrity in a child with schizencephaly unilateral open lip: case report

RESUMEN La esquizencefalia es una malformación poco común del sistema nervioso central, caracterizada por la presencia de hendiduras encefálicas que se extienden desde la superficie pial hasta los ventrículos laterales. Habitualmente se asocia a otras comorbilidades, como parálisis cerebral infantil y crisis convulsivas, que afectan de manera significativa la calidad de vida, el desenvolvimiento social y la adaptación ambiental de los pacientes. Es una entidad cuyo tratamiento es sintomático, por lo cual el abordaje se enfoca en el control de las convulsiones y en la rehabilitación, la cual minimiza el retraso neuro-psicológico que pueden presentar estos pacientes. Se reporta el caso de un paciente pediátrico con esquizencefalia de labio abierto (el subtipo clínico que cursa con peor pronóstico) con una evolución clínica favorable, libre de crisis convulsivas y sin necesidad de farmacoterapia. Actualmente, después de haber realizado un proceso de rehabilitación adaptada y temprana, presenta un déficit neurológico mínimo, con un desarrollo motor y psicológico completo, y un desenvolvimiento social satisfactorio.

SUMMARY Schizencephaly is an uncommon malformation of the central nervous system, characterized by the presence of encephalic clefts that extend from the pial surface to the lateral ventricles. It is usually associated with other comorbidities, such as infantile cerebral palsy and seizures, which significantly affect the quality of life, social development and environmental adaptation of patients. It is an entity whose treatment is symptomatic, for which the approach focuses on the control of seizures and rehabilitation, which minimizes the neuro psychological delay that these patients may present. We report the case of a pediatric patient with open lip schizencephaly (the clinical subtype with the worst prognosis) with a favorable clinical course, free of seizures and without the need for pharmacotherapy. Currently, after having carried out an adapted and early rehabilitation process, it presents a minimal neurological deficit, with a complete motor and psychological development, and a satisfactory social development.

Control temprano de los factores de mal pronóstico en el abordaje de los pacientes con eventos cerebrovasculares isquémicos / Early control of the factors of poor prognosis in the approach of patients with ischemic cerebrovascular events

RESUMEN OBJETIVO: Describir aspectos generales en relación con los eventos cerebrovasculares (ECV) isquémicos, así como los principales factores pronósticos que se han relacionado con el desenlace y la recuperación funcional posterior al evento cerebrovascular. MATERIALES Y MÉTODOS: Se realizó una revisión narrativa utilizando bases de datos (PubMed, Science Direct, MEDLINE), plataformas virtuales (National Institutes of Health) y publicaciones del Acta Neurológica Colombiana. RESULTADOS: Ser mujer, la edad avanzada, la inatención (negligencia), la gravedad del compromiso cognitivo y de la función ejecutiva, la desnutrición, y comorbilidades como la neumonía se asocian con un peor pronóstico en los 90 días posteriores al evento. Las alteraciones en la esfera mental (delirio), alteración de la conciencia, hemiplejia o parálisis de la mirada conjugada y el origen cardioembólico del ECV son algunos de los factores asociados con la mortalidad. La lateralidad hemisférica es una variable importante a tener en cuenta para valorar el pronóstico y la discapacidad funcional residual posevento; sin embargo, la evidencia actual es poco concluyente y algo contradictoria en relación con su rol como factor pronóstico. CONCLUSIONES: Es importante un diagnóstico temprano y una intervención adecuada de los pacientes afectados con ECV isquémico, así como el control precoz de los factores modificables de mal pronóstico. Entre los no modificables, la lateralidad hemisférica podría ser más bien un criterio de selección para un programa de rehabilitación específico y personalizado, pues indudablemente existe un compromiso cognitivo y del lenguaje que difiere sustancialmente en relación con la ubicación topográfica de la lesión.

SUMMARY OBJETIVE: To describe general aspects related to acute ischemic stroke (AIS), as well as to know the main prognostic factors that have been related to the outcome and functional recovery after the AIS. MATERIALS AND METHODS: A narrative review was performed using databases (PubMed, Science-Direct, MEDLINE), virtual platforms (National Institutes of Health) and publications of the Colombian Neurological Record. RESULTS: Being female, advanced age, inattention (neglect), severity of cognitive and executive function impairment, malnutrition, and comorbidities such as pneumonia are associated with a worse prognosis in the 90 days after the event. Alterations in the mental sphere (delirium), altered consciousness, hemiplegia or paralysis of the conjugate gaze and the cardioembolic origin of the AIS are some of the factors that are associated with higher mortality. Hemispheric laterality is an important variable to consider in assessing the prognosis and residual functional disability post-event; however the current evidence is inconclusive and somewhat contradictory. CONCLUSIONS: Early diagnosis and adequate intervention of patients with AIS and early control of modifiable factors of poor prognosis are important. Among the non-modifiable, hemispheric laterality may be more a selection criterion for a specific and personalized rehabilitation program, since there is undoubtedly a cognitive and language compromise that differs substantially in relation to the topographical location of the ischemic lesion.
