Trauma de vía aérea/Airway injury

Trauma de la vía aérea. Una revisión de epidemiología, mecanismos de lesión, diagnóstico y tratamiento Airway trauma: a review on epidemiology, mechanisms of injury, diagnosis and treatment. Prokakis C, Koletsis EN1, Dedeilias P, Fligou F, Filos K, Dougenis D. J Cardiothorac Surg. 2014 Jun 30;9:117. doi: 10.1186/1749-8090-9-117. Abstract Airway injuries are life threatening conditions. A very little number of patients suffering air injuries are transferred live at the hospital. The diagnosis requires a high index of suspicion based on the presence of non-specific for these injuries symptoms and signs and a thorough knowledge of the mechanisms of injury. Bronchoscopy and chest computed tomography with MPR and 3D reconstruction of the airway represent the procedures of choice for the definitive diagnosis. Endotracheal intubation under bronchoscopic guidance is the key point to gain airway control and appropriate ventilation. Primary repair with direct suture or resection and an end to end anastomosis is the treatment of choice for patients suffering from tracheobronchial injuries (TBI). The surgical approach to the injured airway depends on its location. Selected patients, mainly with iatrogenic injuries, can be treated conservatively as long as the injury is small (<2 cm), a secure and patent airway and adequate ventilation are achieved, and there are no signs of sepsis. Patients with delayed presentation airway injuries should be referred for surgical treatment. Intraoperative evaluation of the viability of the lung parenchyma beyond the site of stenosis/obstruction is mandatory to avoid unnecessary lung resection. PDF  Tratamiento de las lesiones traqueobranquiales Management of tracheobronchial injuries. Altinok T, Can A. Eurasian J Med. 2014 Oct;46(3):209-15. doi: 10.5152/eajm.2014.42. Epub 2014 Aug 26. Abstract Tracheobronchial injury is one of cases which are relatively uncommon, but must be suspected to make the diagnosis and managed immediately. In such a case, primary initial goals are to stabilize the airway and localize the injury and then determine its extend. These can be possible mostly with flexible bronchoscopy conducted by a surgeon who can repair the injury. Most of the penetrating injuries occur in the cervical region. On the other hand, most of the blunt injuries occur in the distal trachea and right main bronchus and they can be best approached by right posterolateral thoracotomy. The selection of the manner and time of approaching depends on the existence and severity of additional injuries. Most of the injuriescan be restored by deploying simple techniques such as individual sutures, while some of them requires complex reconstruction techniques. Apart from paying attention to the pulmonary toilet, follow-up is crucial for determination of anastomotic technique or stenosis. Conservative treatment may be considered an option with a high probability of success in patients meeting the criteria, especially in patients with iatrogenic tracheobronchial injury.

Articulo y Resumen Cortesia del Dr. David Camarena Enriquez
En 2010 más de 7,7 millones de niños murieron antes de su quinto cumpleaños. 98 % de estas muertes se produjeron en los países en desarrollo, y las estimaciones recientes han atribuido cientos de miles de estas muertes a la lactancia materna subóptima . Este es un estudio de prevalencia estimada de la lactancia materna subóptima para 137 países en desarrollo 1990-2010 . Estas estimaciones se comparan con la OMS para lactantes alimentados al seno materno.
La lactancia materna es una intervención efectiva de la salud infantil que no requiere una amplia infraestructura en salud. Las mejoras en las tasas de lactancia materna exclusiva pueden contribuir a la reducción de las desigualdades en la mortalidad infantil en los países en desarrolloPara ver articulo completo hacer click aquí: http://bit.ly/1NnH4qc

Articulo y Resumen Cortesia del Dr. David Camarena Enriquez
Objetivo: presentar un análisis bibliométrico de los artículos sobre alimentación infantil, publicados en revistas biomédicas mexicanas, entre 2000-2009. Método: se revisaron las revistas publicadas por instituciones públicas o gremiales cuyas especialidades (p. ej. ginecología, pediatría) pudieran tratar el tema. Seis revistas publicaron 3,077 artículos sobre diversas temáticas, de los cuales solo 78 trataron sobre alimentación infantil. Estos se analizaron mediante la codificación del título, resumen, frecuencia de palabras clave y pertenencia institucional del primer autor(a); el contenido fue clasificado en siete nodos temáticos. Resultados: el nodo más frecuente fue modelos alimentarios; lactancia materna apareció 10 veces en las palabras clave, y la institucionalidad autoral expresó la Ley de Lotka. Los resultados mostraron la idea predominante de un modelo alimentario unívoco, la asunción generalizada de la universalidad de la díada madre-bebé, la focalización en entidades medicoclínicas y la omisión de agentes sociales involucrados en el fenómeno alimentario. Conclusión: si la bibliometría dilucida el conocimiento explícito y los discursos biomédicos actuales, de este análisis se desprende que el conocimiento requerido para el diseño y operación de políticas públicas de bienestar maternoinfantil en México resulta insuficiente para cumplir las recomendaciones sanitarias internacionalesPara ver articulo completo hacer click aquí: http://bit.ly/1z4Kgeq

Bupivacaína administrada intratecal vs rectal en el manejo del dolor rectal intratable por cáncer en cuidado paliativo

Bupivacaína administrada intratecal vs rectal en el manejo del dolor rectal intratable por cáncer en cuidado paliativo Bupivacaine administered intrathecally versus rectally in the management of intractable rectal cancer pain in palliative care. Zaporowska-Stachowiak I, Kowalski G2, Luczak J, Kosicka K4, Kotlinska-Lemieszek A, Sopata M, Główka F. Onco Targets Ther. 2014 Oct 6;7:1541-50. doi: 10.2147/OTT.S61768. eCollection 2014. Abstract BACKGROUND: Unacceptable adverse effects, contraindications to and/or ineffectiveness of World Health Organization step III "pain ladder" drugs causes needless suffering among a population of cancer patients. Successful management of severe cancer pain may require invasive treatment. However, a patient's refusal of an invasive procedure necessitates that clinicians consider alternative options. OBJECTIVE: Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures), and to evaluate the effect of the mode of administration (intrathecal versus rectal) on the bupivacaine plasma concentration. CASES: We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain. The first case is a female with vulvar cancer, and malignant infiltration of the rectum/vagina. Bupivacaine was used intrathecally (0.25-0.5%, 1-2 mL every 6 hours). The second case is a female with ovarian cancer and malignant rectal infiltration. Bupivacaine was adminstered rectally (0.05-0.1%, 100 mL every 4.5-11 hours). METHODS: Total bupivacaine plasma concentrations were determined using the high-performance liquid chromatography-ultraviolet method. RESULTS: Effective pain control was achieved with intrathecal bupivacaine (0.077-0.154 mg*kg(-1)) and bupivacaine in enema (1.820 mg*kg(-1)). Intrathecal bupivacaine (0.5%, 2 mL) caused a drop in blood pressure; other side effects were absent in both cases. Total plasma bupivacaine concentrations following intrathecal and rectal bupivacaine application did not exceed 317.2 ng*mL(-1) and 235.7 ng*mL(-1), respectively. Bupivacaine elimination was slower after rectal than after intrathecal administration (t½= 5.50 versus 2.02 hours, respectively). LIMITATIONS: This study reports two cases only, and there could be inter-patient variation. CONCLUSION: Bupivacaine in boluses administered intrathecally (0.25%, 2 mL) provided effective, safe analgesia in advanced cancer patients. Bupivacaine enema (100 mg*100 mL(-1)) was shown to be a valuable option for control of end-of-life tenesmoid cancer pain.

Influencias del sexo sobre el consumo postoperatorio de morfina

Influencias del sexo sobre el consumo postoperatorio de morfina Influences of gender on postoperative morphine consumption. Periasamy S, Poovathai R, Pondiyadanar S. J Clin Diagn Res. 2014 Dec;8(12):GC04-7. doi: 10.7860/JCDR/2014/10770.5319. Epub 2014 Dec 5. Abstract BACKGROUND: Gender related differences on morphine consumption during postoperative period following abdominal surgeries. MATERIALS AND METHODS: Four hundred and fifty ASA I & II patients of either sex (male =231, female = 219), between the age group of 18-65 y undergoing elective intra abdominal surgeries under general anaesthesia were included for the study. Patients with preexisting pain either acute or chronic preoperatively were excluded from the study. Anaesthesia and analgesia protocol during surgery was standardized. Postoperatively, a loading dose was given to achieve the visual analogue scale (VAS) of ≤30 and subjects were connected to patient control analgesia (PCA) pump containing 0.4 mg/ml of morphine configured to deliver a bolus dose (1 mg) with a 5 min lock-out period. The total analgesic requirements along with VAS (visual analog scale) score were analysed between males and females in the first 24 h postoperatively. All demographic data and between group comparisons were analysed with student t-test. Within group comparisons were done by using one-way-ANOVA test and Tukey's Honestly significant Difference test. RESULTS: During the first 24 h, males consumed significantly higher amount of morphine (34.35 ± 6.68 mg) when compared to females (26.78 ± 7.14 mg), p < 0.001. CONCLUSION: We conclude that men require more morphine in the postoperative period than women. KEYWORDS: Morphine; Patient-controlled analgesia; Postoperative pain PDF

Gabapentina en DPO/Gabapentin for POP

Gabapentina en dolor agudo postoperatorio Gabapentin in acute postoperative pain management. Chang CY1, Challa CK1, Shah J1, Eloy JD1. Biomed Res Int. 2014;2014:631756. doi: 10.1155/2014/631756. Epub 2014 Apr 14. Abstract Gabapentin (1-aminomethyl-cyclohexaneacetic acid) is an amino acid that has the structure of the neurotransmitter γ -aminobutyric acid (GABA). It is a novel drug used for the treatment of postoperative pain with antihyperalgesic properties and a unique mechanism of action. Gabapentin and the related, more potent compound pregabalin have been shown to be beneficial in the treatment of neuropathic pain as well as postoperative painfollowing spinal surgery and hysterectomy. This study reviews five aspects of gabapentin: (1) chemical and structural characteristics; (2) pharmacokinetics and pharmacodynamics; (3) application in acute pain management; (4) adverse effects; and (5) drug safety. Overall, gabapentinhas been reported to be a safe and efficacious drug for the treatment of postoperative pain.

Estudio clínico randomizado The effect of gabapentin on reducing pain after laparoscopic gastric bypass surgery in patients with morbidobesity: a randomized clinical trial. Hassani V1, Pazouki A2, Nikoubakht N1, Chaichian S3, Sayarifard A4, Shakib Khankandi A5. Anesth Pain Med. 2015 Feb 1;5(1):e22372. doi: 10.5812/aapm.22372. eCollection 2015. Abstract BACKGROUND: Pain after laparoscopic gastric bypass surgery (LGBP) is a major problem. Gabapentin is an anticonvulsant drug that can be effective in postoperative pain control. OBJECTIVES: This study examined the effect of preoperative administration of gabapentin on reducing pain after LGBP in patients with morbidobesity. PATIENTS AND METHODS: This randomized clinical trial was performed in Hazrat Rasoul Akram Medical Center in Tehran. A total of 60 patientsundergoing LGBP were randomly allocated into two groups; one group received 100 mg of oral gabapentin and the other group received placebo. Painwas evaluated at recovery time, and at the first, second, fourth and sixth hour of surgery by visual analog scale. The number and dose of opioid useafter surgery and incidence of postoperative complications, such as nausea and vomiting, agitation, and headache, were also recorded. RESULTS: The mean pain score in the group receiving gabapentin was significantly lower than the placebo group (P < 0.001). Indications and dose of opioid consumption between the two groups were not statistically significant. Incidence of nausea/vomiting (P = 0.028) as well as agitation (P = 0.037) was significantly lower in the gabapentin group. CONCLUSIONS: Administration of gabapentin before surgery can reduce pain after LGBP. Furthermore, it is not accompanied by significant short-term adverse effects.

Síndrome de fatiga crónica en adolescentes/Chronic fatigue syndrome in adolescents

Umbral de dolor y dolor a la presión en los adolescentes con síndrome de fatiga crónica y controles sanos: un estudio transversal. Pain and pressure pain thresholds in adolescents with chronic fatigue syndrome and healthy controls: a cross-sectional study. Winger A, Kvarstein G, Wyller VB, Sulheim D, Fagermoen E, Småstuen MC, Helseth S. BMJ Open. 2014 Oct 6;4(9):e005920. doi: 10.1136/bmjopen-2014-005920. Abstract OBJECTIVES: Although pain is a significant symptom in chronic fatigue syndrome (CFS), pain is poorly understood in adolescents with CFS. The aim of this study was to explore pain distribution and prevalence, pain intensity and its functional interference in everyday life, as well as pressurepain thresholds (PPT) in adolescents with CFS and compare this with a control group of healthy adolescents (HC). METHODS: This is a case-control, cross-sectional study on pain including 120 adolescents with CFS and 39 HCs, aged 12-18 years. We measuredpain frequency, pain severity and pain interference using self-reporting questionnaires. PPT was measured using pressure algometry. Data were collected from March 2010 until October 2012 as part of the Norwegian Study of Chronic Fatigue Syndrome in Adolescents: Pathophysiology and Intervention Trial. RESULTS: Adolescents with CFS had significantly lower PPTs compared with HCs (p<0.001). The Pain Severity Score and the Pain Interference Score were significantly higher in adolescents with CFS compared with HCs (p<0.001). Almost all adolescents with CFS experienced headache, abdominal pain and/or pain in muscles and joints. Moreover, in all sites, the pain intensity levels were significantly higher than in HCs (p<0.001). CONCLUSIONS: We found a higher prevalence of severe pain among adolescents with CFS and lowered pain thresholds compared with HCs. The mechanisms, however, are still obscure. Large longitudinal population surveys are warranted measuring pain thresholds prior to the onset of CFS. KEYWORDS: PAIN MANAGEMENT; PUBLIC HEALTH PDF

Hígado y embarazo / Liver and pregnancy

Hígado graso agudo del embarazo: Estudio de seguimiento mayor de 6 meses en 25 pacientes Acute fatty liver of pregnancy: over six months follow-up study of twenty-five patients. Xiong HF1, Liu JY1, Guo LM1, Li XW1. World J Gastroenterol. 2015 Feb 14;21(6):1927-31. doi: 10.3748/wjg.v21.i6.1927. Abstract AIM: To evaluate the prognosis of patients with acute fatty liver of pregnancy (AFLP) 6 mo or longer after discharge. METHODS: The records of pregnant patients diagnosed with AFLP at Beijing Ditan Hospital over a 16-year period were reviewed in November 2012. Patients were monitored using abdominal ultrasound, liver and kidney functions, and routine blood examination. RESULTS: A total of 42 patients were diagnosed with AFLP during the study period, and 25 were followed. The mean follow-up duration was 54.5 mo (range: 6.5-181 mo). All patients were in good physical condition, but one patient had gestational diabetes. The renal and liver functions normalized in all patients after recovery, including in those with pre-existing liver or kidney failure. The ultrasound findings were normal in 12 patients, an increasingly coarsened echo-pattern and increased echogenicity of the liver in 10 patients, and mild to moderate fatty liver infiltration in 3 patients. Cirrhosis or liver nodules were not observed in any patient. CONCLUSION: Acute liver failure and acute renal failure in AFLP patients is reversible. Patients do not require any specific long-term follow-up after recovery from AFLP if their liver function tests have normalized and they remain well.

Abstract Pregnancy-related liver disorders accounted for 8% of all maternal deaths at our center from 1999 to 2011. Of the three pregnancy-related liver disorders (acute fatty liver of pregnancy (AFLP), HELLP (Hemolysis, elevated liver enzymes, low platelets) syndrome and pre-eclamptic liver dysfunction, which can lead to adverse maternal and fetal outcome, AFLP is most typically under - diagnosed. Risk of maternal death can be minimised by timely recognition and early/aggressive multi-specialty management of these conditions. Urgent termination of pregnancy remains the cornerstone of therapy for some of these life threatening disorders, but recent advancements in our understanding help us in better overall management of these patients. This review focuses on various aspects of pregnancy-related liver disorders.
