Management of adolescent patients with end-stage arthritis is challenging. Nonoperative treatments may be ineffective and total knee arthroplasty (TKA) is rarely performed. Currently, minimal long-term data are available on the outcomes in this patient population. Our goal was to describe TKA for patients with end-stage arthritis who were aged 20 years and younger.
CONCLUSIONS:
We identified a 95% 10-year implant survivorship utilizing standard TKA components in pediatric patients. Performing a TKA in adolescent patients has long-term potential risks including infection and bone loss but may provide pain relief and good long-term results and should be used with caution.

Resumen

ANTECEDENTES:
El manejo de los pacientes adolescentes con artritis en etapa terminal es un desafío. Los tratamientos no operatorios pueden ser ineficaces y la artroplastia total de rodilla (TKA) rara vez se realiza. Actualmente, se dispone de datos mínimos a largo plazo sobre los resultados en esta población de pacientes. Nuestro objetivo era describir TKA para pacientes con artritis en etapa terminal que tenían 20 años o menos.
CONCLUSIONES:
Se identificó un 95% de supervivencia del implante de 10 años utilizando componentes TKA estándar en pacientes pediátricos. Realizar un TKA en pacientes adolescentes tiene riesgos potenciales a largo plazo incluyendo infección y pérdida ósea, pero puede proporcionar alivio del dolor y buenos resultados a largo plazo y debe utilizarse con precaución.

We aimed to investigate the clinical characteristics of slipped capital femoral epiphysis (SCFE) in patients aged less than 10 years and identify the efficacy of physeal-sparing procedures in this age group. Obesity may be associated more with early-onset SCFE (onset<10 years). Physeal-sparing procedures are safe and effective in preventing leg-length discrepancy and allowing the remodeling of the deformed proximal femur in this age group.
Resumen

El objetivo de este trabajo fue investigar las características clínicas  del deslizamiento de la epífisis femoral de capital SCFE) en pacientes menores de 10 años e identificar la eficacia de los procedimientos de preservación fisiológica de la placa de crecimiento en este grupo de edad.  La obesidad puede estar asociada más con SCFE de inicio precoz (inicio <10 años). Los procedimientos de la preservación de la placa de crecimiento son seguros y efectivos para prevenir la discrepancia entre las piernas y permitir la remodelación del fémur proximal deformado en este grupo de edad.

To assess patient satisfaction, functional and cosmetic outcomes of single-digit ray amputation in hand and identify factors that might affect the outcome.
CONCLUSION:
Following ray amputation, one can predict an approximate 43.3% loss of grip strength and 33.6% loss of pinch strength. The patients can be counselled regarding the expected time off from work, amount of disability and complications after a single-digit ray amputation. Majority of the patients can return to the same occupation after a period of dedicated hand therapy.

Resumen

PROPÓSITO:
Evaluar la satisfacción del paciente, los resultados funcionales y cosméticos de una amputación de rayos de un solo dígito en la mano e identificar los factores que podrían afectar el resultado.
CONCLUSIÓN:
Después de la amputación de rayos, se puede predecir una pérdida aproximada del 43,3% de la fuerza de agarre y una pérdida del 33,6% de la fuerza de pellizco. Los pacientes pueden ser aconsejados con respecto al tiempo esperado fuera del trabajo, la cantidad de discapacidad y las complicaciones después de una amputación de rayos de un solo dígito. La mayoría de los pacientes pueden volver a la misma ocupación después de un período de terapia de mano dedicada.

Alfa bloqueo selectivo versus no selectivo antes de adrenalectomía laparoscópica
Selective Versus Non-selective α-Blockade Prior to Laparoscopic Adrenalectomy for Pheochromocytoma.
Ann Surg Oncol. 2017 Jan;24(1):244-250. doi: 10.1245/s10434-016-5514-7. Epub 2016 Aug 25.
Abstract
BACKGROUND: The optimal preoperative α-blockade strategy is debated for patients undergoing laparoscopic adrenalectomy for pheochromocytomas. We evaluated the impact of selective versus non-selective α-blockade on intraoperative hemodynamics and postoperative outcomes. METHODS: We identified patients having laparoscopic adrenalectomy for pheochromocytomas from 2001 to 2015. As a marker of overall intraoperative hemodynamics, we combined systolic blood pressure (SBP) > 200, SBP < 80, SBP < 80 and >200, pulse > 120, vasopressor infusion, and vasodilator infusion into a single variable. Similarly, the combination of vasopressor infusion in the post-anesthesia care unit (PACU) and the need for intensive care unit (ICU) admission provided an overview of postoperative support. RESULTS: We identified 52 patients undergoing unilateral laparoscopic adrenalectomy for pheochromocytoma. Selective α-blockade (i.e. doxazosin) was performed in 35 % (n = 18) of patients, and non-selective blockade with phenoxybenzamine was performed in 65 % (n = 34) of patients. Demographics and tumor characteristics were similar between groups. Patients blocked selectively were more likely to have an SBP < 80 (67 %) than those blocked with phenoxybenzamine (35 %) (p = 0.03), but we found no significant difference in overall intraoperative hemodynamics between patients blocked selectively and non-selectively (p = 0.09). However, postoperatively, patients blocked selectively were more likely to require additional support with vasopressor infusions in the PACU or ICU admission (p = 0.02). Hospital stay and complication rates were similar. CONCLUSION: Laparoscopic adrenalectomy for pheochromocytoma is safe regardless of the preoperative α-blockade strategy employed, but patients blocked selectively may have a higher incidence of transient hypotension during surgery and a greater need for postoperative support. These differences did not result in longer hospital stay or increased complications.

Manejo perioperatorio actual de los feocromocitomas
Current perioperative management of pheochromocytomas.

Abstract
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, 123I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging. Before surgical removal of the tumors, the optimization of blood pressure, as well as intravascular volume, is an important measure to avoid and suppress perioperative adverse hemodynamic events. Preoperative preparation includes the use of alpha-adrenergic antagonists, beta-adrenergic antagonists with or without other antihypertensive agents, fluid therapy as well as insulin therapy for hyperglycemia if required. Due attention should be given to type and dose of alpha-receptor antagonists to be used and the duration of this therapy to achieve an optimal level of preoperative "alpha-blockade." Despite this preoperative preparation, many patients will have hypertensive crises intraoperatively which need to be promptly and carefully managed by the anesthesia team which requires intensive and advanced monitoring techniques. The most common complication after tumor removal is hypotension which may require fluid therapy and vasopressor support for a few hours. With advancement in surgical and anesthetic techniques, the incidence of severe morbidity and mortality associated with the surgery is low in high volume centers.
