    Full Text Available Con el objetivo de determinar los valores normales de gases en sangre en la arteria umbilical de neonatos a término a 3400 m de altitud se hizo un estudio transversal, realizado en la sangre de la arteria umbilical de 300 neonatos a término, adecuados para la edad gestacional y cuyo parto se dio entre enero de 2010 a diciembre de 2011 en el Hospital Nacional Adolfo Guevara Velazco de EsSalud (Cusco, Perú. Se encontró que la media del pH de neonatos sanos a término fue de 7,33 ± 0,07, los valores para los percentiles 5 y 95 fueron 7,18 y 7,40 respectivamente. En conclusión, se han construido las tablas con los percentiles 5 al 95 para el pH, pO2, pCO2, SO2, p50, exceso de bases y HCO3, de la arteria umbilical de neonatos a término a 3400 m de altitud

    2004-07-01

    Full Text Available El Tribunal Supremo ha condenado a varios obstetras por informar que el cordón umbilical tenía los tres vasos, desactivando así la búsqueda de enfermedades fetales que la arteria umbilical única (AUU habría desencadenado. La condena será éticamente correcta si la AUU está realmente asociada a tales enfermedades. En la población general se detecta un caso de AUU en cada 320 fetos estudiados ecográficamente. En el 68 % de esas detecciones se tratará de un hallazgo aislado, pero aún así aumenta el riesgo de parto prematuro, de peso bajo y de mortalidad perinatal. Por otra parte, el 17 % de estos fetos tendrán, además de la arteria única, cromosomopatías y el 31 % malformaciones anatómicas. Concluyendo, la AUU es realmente un marcador cardinal de riesgo de trastornos fetales, que debe buscarse activamente durante el seguimiento ecográfico del embarazo.

The sentence will be ethically correct only if SUA is really associated with such diseases. SUA is found in about 1 out of every 320 fetuses studied sonographically. In 68% of them, it will be an isolated finding, although it will increase the risks of premature delivery, low birthweight, and perinatal mortality. On the other hand, 17% of these fetuses will have, besides SUA, chromosomal alterations, and 31 % of them, structural malformations. In conclusion, SUA is an important marker of fetal disorders, and it has to be actively searched for during the ultrasonographic monitoring of the gestation.

Por tanto se enfatiza con fuerza el contrasentido de aseverar que el principio y el producto son lo mismo, entendiendo que la semilla es diferente al fruto, citando a Savater, cuando dijo que el que come un huevo no ha comido pollo. El embrión recién fecundado o pre-embrión, es principio, semilla, potencia, quizás un día sea persona, de ahí la conclusión de que no toda vida humana es persona humana.In this essay, more than a linguistic game of terms and expressions, we treat the meanings of human life and the human person, and how this simooms in the habitual language, have been to changed into a sophisticated judicial tool, by the conclusion of the Costa Rican Constitutional Court, who using a mysterious science, has said that once the ovule has been fecund, it is a human being.

The embryo recently fecund or pre-embryo is beginning, seed, potency, maybe one day it will be a human person, from there the conclusion that not all human life is a human person.

    Full Text Available This article reviews in detail the superficial brachiomedian artery (arteria brachiomediana superficialis, a very rare variant of the main arterial trunks of the upper limb. It branches either from the axillary artery or the brachial artery, descends superficially in the arm (similar to the course of the superficial brachial artery and continues across the cubital fossa, runs superficially in the forearm, approaches the median nerve and enters the carpal canal to reach the hand. It usually terminates in the superficial palmar arch. The first drawing was published, in 1830, and the first description was published, in 1844. Altogether, to our knowledge, only 31 cases of a true, superficial brachiomedian artery have been reported (Some cases are incorrectly reported as superficial brachioradiomedian artery or superficial brachioulnomedian artery. Based on a meta-analysis of known, available studies, the incidence is 0.23% in Caucasians and 1.48% in Mongolians. Knowing whether or not this arterial variant is present is important in clinical medicine and relevant for: The catheterization via the radial or ulnar artery; harvesting the vascular pedicle for a forearm flap based on the radial, ulnar or superficial brachiomedian arteries; the possible collateral circulation in cases of the arterial closure; and the surgical management of carpal tunnel syndrome. Its presence can elevate the danger of an injury to the superficially located variant artery or of an accidental injection.

    Umbilical endometriosis is a rare condition, usually following laparoscopic and surgical procedures involving the umbilicus.Spontaneous umbilical endometriosis occurring without any previous abdominal or uterine surgery is extremely rare. The maximal depth of penetration of the umbilical endometriosis described is up to fascial level. There have been only two cases of endometriosis reported arising within umbilical hernia. The authors report a case of a patient with spontaneous umbilical endometriosis associated with a large umbilical hernia, treated by surgical excision and mesh repair of the abdominal wall. To the best of our knowledge, this is the first described case of the association of umbilical endometriosis with a large umbilical hernia that requires prosthetic mesh repair of the abdominal wall defect.

    1995-09-01

    Knowledge of the development, normal sonographic appearance, and potential abnormalities of the umbilical cord is important in fetal assessment. The umbilical cord can be visualized throughout most of gestation and is detectable sonographically soon after visualization of the fetal pole. The normal umbilical cord is 50-60 cm long and may coil as many as 40 times, usually to the left. Abnormalities in umbilical cord size, degree of coiling, attachment, and position can have important implications for the outcome of the pregnancy. Structural abnormalities of the umbilical cord such as single umbilical artery, knots, cysts, and tumors may be associated with fetal distress or malformations. Color Doppler ultrasound (US) is useful in the identification and evaluation of structural abnormalities of the cord. By allowing measurement of blood flow velocity in the umbilical artery, duplex Doppler US may provide additional information in the evaluation of intrauterine growth retardation and twin-twin transfusion syndrome.

Me interesa el cuerpo como materialidad, experiencia y producto de una práctica bastante específica, de la cual surge como un ente natural y trascendente. Para referirme a la práctica de hacer un cuerpo, hago un análisis etnográfico de la asignatura en conjunto: observo los estudiantes, los profesores, los libros, las pinzas, las manos y los cadáveres usados. Este análisis es producto de mi participación durante más de un año en las clases y en los laboratorios de la asignatura de Anatomía, en dos facultades de Medicina, en la ciudad de Bogotá, Colombia. Se trata de una etnografía de una serie de movimientos corporales específicos, con los cuales se aprende a hacer anatomía humana, con un amplio rango de materialidades (cadáveres, libros, dispositivos virtuales, modelos tridimensionales, etcétera. Gracias a mi participación en este espacio de enseñanza, elaboré un diario de campo que luego transcribí, para someterlo a un análisis. En este, me interesa dar cuenta de aquellos momentos en los que una estructura anatómica es producto de las prácticas de la asignatura. Así, este artículo explora, en específico, la manera en que se hacen arterias en el anfiteatro de Anatomía. Mi pregunta no es cómo se identifican determinados vasos sanguíneos en el cuerpo humano, sino cómo se configuran sus distintas propiedades y particularidades en el laboratorio, incluido un nombre que los identifica. La cuestión no es, pues, epistemológica sino ontológica. De esta manera, en este artículo muestro que en el laboratorio surgen sensaciones y trayectorias materiales como si fueran arterias específicas. Para esto, se requiere de un espacio orientado y de la participación de múltiples entidades, heterogéneas y parcialmente conectadas, que enriquecen la experiencia de hacer una arteria en el laboratorio.

    Full Text Available Abstract Background Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and treatment. Method A search of Pubmed was carried out using the term 'umblic*' and 'metastases' or metastasis' revealed no references. Another search was made using the term "Sister Joseph's nodule" or sister Joseph nodule" that revealed 99 references. Of these there were 14 review articles, however when the search was limited to English language it yielded only 20 articles. Articles selected from these form the basis of this report along with cross references. Results The primary lesions usually arise from gastrointestinal or genitourinary tract malignancies and may be the presenting symptom or sign of a primary tumour in an unknown site. Conclusion A careful evaluation of all umbilical lesions, including an early biopsy if appropriate, is recommended. Recent studies suggest an aggressive surgical approach combined with chemotherapy for such patients may improve survival.

    2013-06-01

    Umbilical cable is a kind of integrated subsea cable widely used in the exploration and exploitation of oil and gas field. The severe ocean environment makes great challenges to umbilical maintenance and repair work. Damaged umbilical is usually recovered for the regular operation of the offshore production system. Analysis on cables in essence is a two-point boundary problem. The tension load at the mudline must be known first, and then the recovery load and recovery angle on the vessel can be solved by use of catenary equation. The recovery analysis also involves umbilical-soil interaction and becomes more complicated. Calculation methods for recovery load of the exposed and buried umbilical are established and the relationship between the position of touch down point and the recovery load as well as the recovery angle and recovery load are analyzed.

    Full Text Available La condronecrosis laríngea es una complicación rara y grave que aparece en pacientes sometidos a radioterapia. Presentamos el caso clínico de un paciente con condronecrosis laríngea severa tratada mediante desbridamiento y cobertura con colgajo de perforante de arteria mamaria interna (IMAP. El colgajo se basó en una perforante del segundo espacio intercostal, previa localización con doppler manual. La zona donante se cerró directamente. El colgajo fue viable en un 100%, permitió una adecuada cobertura del defecto y quedó bien adaptado al mismo. La zona donante cicatrizó sin incidencias. Consideramos que el colgajo de perforante de arteria mamaria interna pediculado permite una solución fiable y adecuada para pacientes con condronecrosis laríngea postradioterapia.

    Umbilical cable is a kind of integrated subsea cable widely used in the exploration and exploitation of oil and gas field.The severe ocean environment makes great challenges to umbilical maintenance and repair work.Damaged umbilical is usually recovered for the regular operation of the offshore production system.Analysis on cables in essence is a two-point boundary problem.The tension load at the mudline must be known first,and then the recovery load and recovery angle on the vessel can be solved by use of catenary equation.The recovery analysis also involves umbilicalsoil interaction and becomes more complicated.Calculation methods for recovery load of the exposed and buried umbilical are established and the relationship between the position of touch down point and the recovery load as well as the recovery angle and recovery load are analyzed.The analysis results provide a theoretical reference for offshore on-deck operation.

    2012-07-01

    Since the first umbilical cord blood transplantation (CBT) in 1998, cord blood (CB) has now become one of the most commonly used sources of hematopoietic stem cells for transplantation. CBT has advantages of easy procurement, no risk to donor, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite human leukocyte antigen disparity. Several studies have shown that the number of cells transplanted is the most important factor for engraftment in CBT, and it limits the wide use of CB in adult patients. New strategies for facilitating engraftment and reducing transplantation-related mortality are ongoing in the field of CBT and include the use of a reduced-intensity conditioning regimen, double-unit CBT, ex vivo expansion of CB, and co-transplantation of CB and mesenchymal stem cells. Recently, the results of two international studies with large sample sizes showed that CB is an acceptable alternative source of hematopoietic stem cells for adult recipients who lack human leukocyte antigen-matched adult donors. Along with the intensive researches, development in banking process of CB will amplify the use of CB and offer the chance for cure in more patients.

    Full Text Available El conocimiento preciso de los patrones vasculares permite mejorar los resultados de la reconstrucción regional del pabellón auricular y el diseño de colgajos regionales dependientes de la arteria temporal superficial para la reconstrucción facial. En México, no contamos en la actualidad con descripciones anatómicas de las variantes vasculares normales de la arteria temporal superficial. El objetivo de este trabajo es la descripción de las variantes anatómicas de la arteria temporal superficial a través de la disección de este vaso en 12 regiones tempo-parieto-occipitales en cadáveres. Nuestros resultados muestran que la arteria temporal superficial siempre se divide en dos ramas, una anterior y otra posterior, la distribución de ésta se sitúa en el cuarto más posterior de la región temporal, con una bifurcación alta. La distribución de la anatomía vascular, tomando en cuenta el calibre mayor de la arteria temporal superficial con respecto a la arteria auricular posterior, la ausencia de esta última en 4 de las regiones estudiadas, así como la distancia de dichos vasos con respecto al conducto auditivo externo, sugieren que en nuestra población la irrigación del pabellón auricular depende de la arteria temporal superficial, restándole importancia a la aportación del riego sanguíneo de esta región por parte de la arteria auricular posterior. Nuestro estudio arroja resultados que indican la existencia de variaciones importantes en la anatomía vascular regional que justifican la realización de estudios posteriores que permitan una descripción mas detallada de la misma para aumentar el éxito de las intervenciones quirúrgicas.

  11. Fibular free flap with arteria peronea magna: the role of preoperative balloon occlusion.

    Science.gov (United States)

    Rahmel, Benjamin B; Snow, Thomas M; Batstone, Martin D

    2011-03-01

    The free fibular osteocutaneous flap is a commonly used donor for reconstruction of mandibular defects. Vascular abnormalities and leg trauma are relative contraindications to the use of a fibular free flap. Peroneal arteria magna (PAM) is one such vascular abnormality that may preclude the use of the graft due to the high risk of lower-limb ischemia. Lower-limb angiography is the standard for assessing the lower-limb vascular anatomy; however, the indications remain controversial. Although balloon occlusion has been used to assess the vascular supply in distal bypass surgery, there have no reported cases of balloon occlusion to assess the viability of the distal extremity with PAM. Intraoperative assessment of vascular anatomy with an aborted harvest can lead to significant morbidity and cost. Balloon occlusion provides a relatively safe and minimally invasive technique for assessment of potential lower-limb ischemia in patients with PAM.

    Full Text Available La endotelina-1 es un péptido vasoconstrictor producido por el endotelio vascular, cuyos niveles plasmáticos están aumentados en los pacientes con cáncer colorrectal y que puede participar en la regulación del flujo sanguíneo tumoral. Para estudiar si la respuesta a este péptido está alterada en las arterias tumorales, se obtuvieron, de 13 pacientes intervenidos quirúrgicamente por cáncer colorrectal, arterias mesentéricas irrigando el tumor y arterias mesentéricas de una región alejada del tumor, y asimismo se obtuvieron arterias mesentéricas de pacientes intervenidos por diverticulitis (n = 4 o enfermedad inflamatoria intestinal (n = 3. Las arterias mesentéricas se montaron en una preparación para el registro de la contracción isométrica en un baño de órganos, encontrándose que la endotelina-1 producía contracción en los tres tipos de arterias, pero la sensibilidad a este péptido fue mayor en las arterias irrigando el tumor que en las arterias alejadas del tumor o en las arterias de pacientes sin patología tumoral. Estos resultados indican que la endotelina-1 puede regular el flujo sanguíneo en los tumores colorrectales, produciendo una mayor vasoconstricción en las arterias que irrigan el tumor que en las arterias no tumorales.Endothelin-1 is an endothelium-derived vasoconstrictor peptide whose plasma levels are increased in patients with colorectal cancer, and which may be involved in tumor blood flow regulation. To study whether response to this peptide is altered in tumor arteries, mesenteric arteries supplying blood flow to colorectal tumors, and mesenteric arteries far from said tumors were obtained from 13 patients undergoing colectomy; mesenteric arteries were also obtained from patients with diverticulitis (n = 4 or inflammatory bowel disease (n = 3.

    Full Text Available Son muchos los conceptos que condicionan la bioética, que pueden hacer que prospere o naufrague. Nos centramos aquí en dos de ellos, a saber, el concepto de dependencia, que funciona como necesario complemento del de autonomía, y el concepto de familia humana, que tal vez debería funcionar como sustituto en contextos morales del de especie humana. Ambos remiten en el fondo a otro concepto, de larga tradición filosófica, el de naturaleza humana, que ha vuelto al centro del debate en los últimos años. La modernidad puede ser caracterizada como una búsqueda de la autonomía. La autonomía en muchos sentidos es un objetivo justo y deseable. Sin embargo, el énfasis unilateral en la autonomía ha generado una antropología parcial. De ahí la importancia de pensar también una antropología de la dependencia que vincule a los miembros de la familia humana.

    2012-01-01

    Concomitant mesh repair of large umbilical hernias and abdominoplasty pose a serious risk of devascularizing the umbilical stalk. A technique of placing mesh in a sublay manner, deep to the fascial defect, for an umbilical herniorrhaphy to avoid damage to the deep umbilical perforators during an abdominoplasty is described.

    Full Text Available Umbilical hernias large enough to contain a gravid uterus are rare. We report a case of a woman with prolapse of a gravid uterus through a previously repaired umbilical hernia. Our plans for elective surgery with caesarean section and hernia repair were foiled by poor compliance. The hernia was repaired during an emergency caesarean section. We provide details of her management and briefly review the literature on umbilical hernias and pregnancy. Surgical management offers an opportunity for hernia repair and can ensure a safe delivery for the mother and child.

    The repair of umbilical and epigastric hernias still represents a challenge to surgeons. Although a common and relatively simple procedure, there is no exact protocol today on how the repair should be done. The Mayo technique and its alterations could not stand the test of time: a recurrence rate of 20% and higher is not acceptable for any surgical procedure. Although there is no consensus opinion, one thing is clear: the importance of an anatomic repair without tension and without an artificial enlargement of the defect. In 1987 Lichtenstein reported on 6321 cases of herniorraphy with a tension free repair, and in 1994 Stuart reemphasized that special importance in his editorial in the Lancet. A newer study from Brancato and coworkers in Italy also states the advantage of a tension-free prosthetic repair in 16 patients with epigastric hernia. We have gone even further and recommend a tailored-to-the-patient repair using a customized polypropylene mesh and a one-layer running suture. The advantages should be obvious: no artificial creation of an even bigger than original defect, a completely tension-free repair, and little to no recurrence of the hernia. Our results clearly prove that assumption. Moreover, the procedure is extremely safe and complications are very rare and minor. We conclude that using a mesh plug in a customized tension-free repair of umbilical and epigastric hernia shows many advantages over the commonly used methods. And we finally conclude with the words of Albert Einstein: "The only source of knowledge is experience."

    Abdominal wall hernias are often diagnosed on clinical examination or encountered intraoperatively during an abdominoplasty. Traditional surgical techniques for abdominoplasty and umbilical hernia repair, when performed simultaneously, can potentially compromise the vascular supply to the umbilicus. The authors describe a simplified surgical technique for the correction of umbilical hernias in conjunction with abdominoplasty. This procedure avoids any fascial incisions immediately adjacent to the umbilicus, thereby maintaining a maximal blood supply to the umbilical stalk. Over a six-year period, 17 patients underwent the described procedure. None have had a recurrence of their hernia or umbilical necrosis, and the aesthetics of the umbilicus have been improved.

    2012-10-15

    Purpose: This study was designed to investigate the long-term angiographic and clinical outcomes of percutaneous transluminal angioplasty (PTA) of the arteria profunda femoralis (PFA), in a series of patients suffering from critical limb ischemia (CLI) or severe intermittent claudication (IC). Methods: Our department's database was searched to identify patients who underwent PTA or bail-out stenting of the PFA. Among the study's inclusion criteria were Rutherford categories 3-6 and {>=}70% stenosis of the PFA. Only de novo stenotic lesions were assessed. Primary endpoints were technical success, angiographic lesion primary patency, angiographic binary in-lesion restenosis, and target lesion recanalization (TLR) rates. Secondary endpoints included patient survival, limb salvage, and complication rates. Patient's baseline demographics, lesion, and procedural details were analyzed. Results: Between 2001 and 2011, 20 consecutive patients (17 males) with a mean age of 73 {+-} 9 (range 53-87) years underwent PTA or bail-out stenting in 23 PFA lesions. Critical limb ischemia was the indication in eight of 20 patients (40%). The mean lesion length was 31 {+-} 9.5 mm. The procedural technical success was 100% (23/23), whereas mean time angiographic and clinical follow-up was 26.8 {+-} 24.6 months. According to the Kaplan-Meier analysis, primary patency and binary restenosis rate were 95 and 86.1% respectively up to 8 years follow-up. No TLR procedures were performed. The 8-year patient survival and limb salvage rates were 87.5 and 84.7% respectively. Conclusions: PTA or stenting of focal, stenotic, PFA lesions, in patients suffering from CLI or IC, exhibit high long-term primary patency rates, as well as low binary restenosis and TLR rates. Large, multicenter studies are required to validate these results.

    2003-01-01

    Full Text Available Dissektionen der kraniozervikalen Gefäße, inbesondere der Arteria carotis, zählen zu den häufigsten Ursachen ischämischer zerebrovaskulärer Ereignisse bei jüngeren Patienten. Die ischämische Symptomatik wird durch eine Wühlblutung in die Gefäßwand verursacht, welche entweder zu einer Minderung des zerebralen Blutflusses und/oder zu einer lokalen Thrombosierung mit nachfolgender Embolisation führt. Karotisdissektionen können durch ein mechanisches Trauma hervorgerufen werden, sie entstehen aber auch spontan oder sind dann bei einem Teil der Patienten mit Bindegewebserkrankungen assoziiert. Zu den häufigsten Symptomen zählen Kopfschmerzen, zervikaler Schmerz und Horner-Syndrom. Die zerebrale Ischämie führt meist zu einer transienten ischämischen Attacke (TIA oder zu einem ischämischen Infarkt im Stromgebiet der Arteria cerebri media der betroffenen Seite. Auch eine Amaurosis fugax kann auftreten. Trotz neuer technischer Möglichkeiten stellen Dissektionen der hirnversorgenden Gefäße nach wie vor eine diagnostische Herausforderung dar. Die digitale Subtraktionsangiographie gilt derzeit noch als Goldstandard zur Diagnostik, wird aber in vielen Fällen zunehmend durch neue nichtinvasive bildgebende Verfahren ersetzt oder ergänzt. Stenose oder Verschluß des betroffenen Gefäßes bilden sich in den meisten Fällen innerhalb von zwei Monaten nach dem Ereignis zurück. Therapeutische Maßnahmen haben vor allem die Verhinderung embolischer Komplikationen zum Ziel. Die gegenständliche Arbeit soll anhand von Fallbeispielen und einer Literaturübersicht klinisch relevante Aspekte und Probleme bei Diagnostik und Therapie der Dissektion der Arteria carotis aufzeigen.

    There is a lack of consensus about the surgical management of umbilical hernias. The aim of this study is to analyze the medium-term results of 934 umbilical hernia repairs. In this study, 934 patients with an umbilical hernia underwent surgery between 2004 and 2010, 599 (64.1%) of which were evaluated at least one year after the surgery. Complications, recurrence, and the reoperation rate were analyzed. Complications were observed in 5.7 per cent of the patients. With a mean follow-up time of 35.5 months, recurrence and reoperation rates were 3.8 per cent and 4.7 per cent, respectively. A higher percentage of female patients (60.9 % vs 29 %, P = 0.001) and a longer follow-up time (47.4 vs 35 months, P = 0.037) were observed in patients who developed a recurrence. No significant differences were observed between complications and the reoperation rate in patients who underwent Ventralex(®) preperitoneal mesh reinforcement and suture repair; however, a trend toward a higher recurrence rate was observed in patients with suture repair (6.5 % vs 3.2 %, P = 0.082). Suture repair had lower recurrence and reoperation rates in patients with umbilical hernias less than 1 cm. Suture repair is an appropriate procedure for small umbilical hernias; however, for larger umbilical hernias, mesh reinforcement should be considered.

  16. Evolution of umbilicals in Brazil: optimizing deepwater umbilical applications with thermoplastic hoses and steel tubes

    Energy Technology Data Exchange (ETDEWEB)

    Guerra Neto, Mauro Del [DuPont do Brasil S.A., Barueri, SP (Brazil)

    2008-07-01

    Subsea umbilicals in the past 25 years have evolved in parallel with other subsea oil and gas technologies, as the search for hydrocarbons needed to drive the global economy has led offshore exploration and development companies to seek reserves ever-farther from shore in water thousands of meters deep. Relegated to little more than afterthought status before the push into deep water, modern umbilicals have now become crucial components linking deep water producers to their subsea wells, controlling subsea production systems through hydraulic and electrical power and injecting production chemicals for corrosion-, scale-, and hydrate-inhibition at subsea well heads. Particularly in subsea developments involving several deep water wells, umbilicals today are integral to both the production-system design and the chosen operating strategy. Failure of an umbilical linking a subsea well head in deep water to a host production facility can inflict severe economic consequences upon an operator by impairing production operations or halting production altogether. The additional cost of repairing or replacing a failed umbilical can run into the millions of dollars. As offshore oil and gas production has moved into ever-deeper water, umbilical manufacturers have begun introducing new stronger materials to handle the inherently higher pressures and temperatures. Today, two types of construction are used for fluid conduits in umbilical systems deployed in deep water: thermoplastic hoses and steel tubes. Steel tubes are generally more expensive than thermoplastic hoses, relatively stiff and considered to have high tensile strength, while thermoplastic hoses are extremely flexible and exhibit lower tensile strength. This lower tensile strength of the hoses may be compensated by including steel wire armoring in the umbilical. This also provides the added benefits of additional mechanical protection compared with the equivalent unarmored steel-tubes umbilicals. When either

    2007-01-01

    We report a rare case of primitive umbilical endometriosis associated with umbilical hernia, which required wide umbilical resection and immediate reconstruction performed according to a recently described technique. A wide resection of the peritoneal sac was performed because of the possible presence of endometrial tissue inside. The hernia was repaired according to Mayo's technique. Umbilical reconstruction was performed using two semicircular skin flaps shaped into in an ellipse preoperatively drawn on the skin with a vertical orientation. The surgical approach described in this report allowed easy hernia repair and umbilical reconstruction. No prosthesis was used because of the small size of the hernia and lack of literature data on prosthesis use in endometriosis. The aesthetic result was considered satisfactory 6 months after the operation because of absence of hypertrophic scars and in view of the anatomical aspect of the new umbilicus. No recurrence was observed within this time frame.

The discussion, I argue, is connected to the Stoic early concern on the topic and its main lines of development are to be influential in later thinkers as St. Th. Aquinas, L. Valla and G.W. Leibniz. Basically, Boethius' doctrine means that it is not only the human reason by itself what makes the man free, but also the end of reason, i.e., God, who is eternally present to necessary and contingent processes in the universe. This is suggested by his final words on the power of prayer

    Full Text Available A raiva humana se mantém como problema de Saúde Pública, especialmente nas áreas urbanas, onde o cão atua como principal reservatório e fonte imediata de infecção. A deficiência de programas de controle de cães vadios, de imunização sistemática e de educação sanitária, contribui para a perpetuação da cadeia epidemiológioa. O presente estudo analisa todos os casos de raiva humana, observados em habitantes do Estado da Guanabara, no período 1965-1969, segundo as variáveis: idade, sexo, côr, variação estacional, período de incubação e de duração da fase clínica, fonte de infecção, local de mordedura e uso de vacina posterior à exposição. Os principais resultados foram: 1. A ravia na Guanabara, parece ser mais comum nos grupos etários mais jovens e nos homens. 2. Não se observou variação estacional. 3. O período de incubação mediano foi de 45 dias e de duração da fase clínica de 3 dias. 4. Ocorreu uma associação entre período de incubação menor e vacinação incompleta.

  2. Evidence-based pathology: umbilical cord coiling.

    2010-12-01

    The generation of a pathology test result must be based on criteria that are proven to be acceptably reproducible and clinically relevant to be evidence-based. This review de-constructs the umbilical cord coiling index to illustrate how it can stray from being evidence-based. Publications related to umbilical cord coiling were retrieved and analysed with regard to how the umbilical coiling index was calculated, abnormal coiling was defined and reference ranges were constructed. Errors and other influences that can occur with the measurement of the length of the umbilical cord or of the number of coils can compromise the generation of the coiling index. Definitions of abnormal coiling are not consistent in the literature. Reference ranges defining hypocoiling or hypercoiling have not taken those potential errors or the possible effect of gestational age into account. Even the way numerical test results in anatomical pathology are generated, as illustrated by the umbilical coiling index, warrants a critical analysis into its evidence base to ensure that they are reproducible or free from errors.

    Once considered a waste product that was discarded with the placenta, umbilical cord blood is now known to contain potentially life-saving hematopoietic stem cells. When used in hematopoietic stem cell transplantation, umbilical cord blood offers several distinct advantages over bone marrow or peripheral stem cells. However, umbilical cord blood collection is not part of routine obstetric care and is not medically indicated. Umbilical cord blood collection should not compromise obstetric or neonatal care or alter routine practice for the timing of umbilical cord clamping. If a patient requests information on umbilical cord blood banking, balanced and accurate information regarding the advantages and disadvantages of public and private umbilical cord blood banking should be provided. The routine storage of umbilical cord blood as "biologic insurance" against future disease is not recommended.

    2012-01-01

    Full Text Available Background. Single Incision Laparoscopic Surgery (SILS has been highlighted in the recent literature as a means of performing a range of common, minimal access, paediatric surgical procedures. The primary attraction is the absence of visible scarring. Aim. This study aims to describe a cosmetically advantageous means of SILS port placement in children, which preserves the umbilical profile. Methods. We describe a paediatric case series utilising a semicircular incision in the superior umbilical fold for SILS procedures. The linea alba is exposed over 2 cm just superior to the umbilical ring and stay sutures are applied. A vertical incision is made over this distance without entering the umbilical ring. Data were recorded prospectively in a Microsoft Excel database. Results. Twenty-one cases were performed in a 1-year period. Ten appendicectomies, 5 ovarian/paraovarian cystectomies, 2 Palomo procedures, 3 nephrectomy/heminephrectomies, and 1 Meckel’s diverticulectomy were performed. There was 1 wound infection. No incisional hernias occurred. Discussion. We believe that our technique, which maintains the integrity of the umbilical ring and allows preservation of the umbilical profile, offers a distinct cosmetic advantage over other incisions for SILS which distort it. Conclusion. We have demonstrated the aesthetic benefits of utilising a superior umbilical-fold incision for SILS in children.

    Full Text Available While umbilical hernias frequently occur during pregnancy, the few reported cases of uterine or fibroid incarceration in ventral hernias during pregnancy all involved incisional abdominal wall defects from prior laparotomies and Cesarean sections; none involved umbilical hernias. We discuss the case of a 42-year-old well-developed, well-nourished grand multiparous woman (G8P7 with a huge umbilical hernia containing a 38-week gravid uterus, as well as her management and the avoidance of known complications that have occurred in similar incisional hernia cases. Successful pregnancy outcomes can occur in cases of pregnancies in ventral hernias, even in resource-poor settings that have Cesarean section capabilities

    Transumbilical surgical procedures have been reported to be a feasible, safe, and cosmetically excellent procedure for various pediatric surgical diseases. Umbilical loop colostomies have previously been created in patients with Hirschsprung's disease, but not in patients with anorectal malformations (ARMs). We assessed the feasibility and cosmetic results of temporal umbilical loop colostomy (TULC) in patients with ARMs. A circumferential skin incision was made at the base of the umbilical cord under general anesthesia. The skin, subcutaneous tissue, and fascia were cored out vertically, and the umbilical vessels and urachal remnant were individually ligated apart from the opening in the fascia. A loop colostomy was created in double-barreled fashion with a high chimney more than 2 cm above the level of the skin. The final size of the opening in the skin and fascia was modified according to the size of the bowel. The bowel wall was fixed separately to the peritoneum and fascia with interrupted 5-0 absorbable sutures. The bowel was opened longitudinally and everted without suturing to the skin. The loop was divided 7 days postoperatively, and diversion of the oral bowel was completed. The colostomy was closed 2-3 months after posterior saggital anorectoplasty through a peristomal skin incision followed by end-to-end anastomosis. Final wound closure was performed in a semi-opened fashion to create a deep umbilicus. TULCs were successfully created in seven infants with rectourethral bulbar fistula or rectovestibular fistula. Postoperative complications included mucosal prolapse in one case. No wound infection or spontaneous umbilical ring narrowing was observed. Skin problems were minimal, and stoma care could easily be performed by attaching stoma bag. Healing of umbilical wounds after TULC closure was excellent. The umbilicus may be an alternative stoma site for temporary loop colostomy in infants with intermediate-type anorectal malformations, who undergo radical

    Umbilical and epigastric hernias are primary midline defects that are present in up to 50% of the population. In the United States, only about 1% of the population carries this specific diagnosis, and only about 11% of these are repaired. Repair is aimed at symptoms relief or prevention, and the patient's goals and expectations should be explicitly identified and aligned with the health care team. This article details some relevant and interesting anatomic issues, reviews existing data, and highlights some common and important surgical techniques. Emphasis is placed on a patient-centered approach to the repair of umbilical and epigastric hernias.

    2014-01-01

    Full Text Available De la Segunda Guerra Mundial en adelante, la dignidad humana es recogida en muchas constituciones, declaraciones de derechos y tratados internacionales. Esto no significa que sea un concepto nuevo, pues su significado puede rastrearse sin dificultad en la tradición judeo-cristiana y, mucho más tarde, en la influyente comprensión kantiana; y tampoco significa que no haya tenido relación con el Derecho antes de 1945. Por otro lado, las nuevas tendencias filosóficas y antropológicas así como la politización del hombre, junto con los avances de la técnica, explican su presencia cada vez mayor en el Derecho. Sin embargo, la inclusión de la dignidad en los textos jurídicos no es capaz de agotar su significado —ni aunque los textos sean los constitucionales—, y el hecho de que los jueces la aleguen no significa que la empleen realmente como criterio para su decisión, como puede verse al estudiar algunas sentencias relevantes.

  11. Porous nematic microfluidics for generation of umbilic defects and umbilic defect lattices

    Aplinc, Jure; Morris, Stephen; Ravnik, Miha

    2016-06-01

    We demonstrate that porous nematic microfluidics is a potential route for the generation of nematic umbilic defects and regular umbilic defect lattices. By using numerical modeling we show that the mutual (backflow) coupling between the flow velocity and the orientation director field of the nematic liquid crystal leads to the formation of positive umbilic defects at local peaks and to the formation of negative umbilic defects at the local saddles in the flow profile. The number of flow peaks and the index of the flow saddles (i.e., the number of the valleys) are shown to be directly related to the strength of the umbilic defect, effectively relating the two fields at the geometrical level. The regular arrangement of the barriers in the porous channels is demonstrated to lead to the formation of regular lattices of umbilic defects, including square, triangular, and even kagome lattices. Experimental realization of such systems is discussed, with particular focus on microfluidic-tunable birefringent photonic band structures and lattices.

  12. The umbilical and paraumbilical veins of man.

    Martin, B F; Tudor, R G

    During its transit through the umbilicus structural changes occur in the thick wall of the extra-abdominal segment of the umbilical vein whereby the components of the intra-abdominal segment acquire an essentially longitudinal direction and become arranged in fibro-elastic and fibro-muscular zones. The vein lumen becomes largely obliterated by asymmetrical proliferation of loose subendothelial conective tissue. The latter forms a new inner zone within which a small segment of the lumen persists in an eccentric position. This residual lumen transmits blood to the portal system from paraumbilical and systemic sources, and is retained in the upper part of the vein, even in old age. A similar process of lumen closure is observed in the ductus venosus. In early childhood the lower third of the vein undergoes breakdown, with fatty infiltration, resulting in its complete division into vascular fibro-elastic strands, and in old age some breakdown occurs in the outermost part of the wall of the upper two thirds. The paraumbilical veins are thick-walled and of similar structure to the umbilical vein. Together they constitute an accessory portal system which is confined between the layers of the falciform ligament and is in communication with the veins of the ventral abdominal wall. The constituents form an ascending series, namely, Burow's veins, the umbilical vein, and Sappey's inferior and superior veins. The main channel of Sappey's inferior veins may be the remnant of the right umbilical vein since it communicates with the right rectus sheath and often communicates directly with the portal system within the right lobe of the liver. The results are of significance in relation to clinical usage of the umbilical vein.

    Full Text Available Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex virus (HSV type 2 at 36 weeks of gestational age. She received oral acyclovir (400 mg three times daily for 10 days. At the gestational age of 38 weeks and 5 days, fetal activity decreased and NST was nonreactive. She was delivered by cesarean section and a true umbilical cord knot was found. Four years later, in her second pregnancy, another true knot was seen.Conclusion: Excessively long umbilical cords are more likely to be associated with true knots. Genetics has an important role in determining cord length and occurrence of true knots.

    The fetal growth of the piglet is highly dependent on its placenta, and the newborn piglet birth weight is highly associated with postpartum death. However, there is little information available in the literature on the assessment of the placenta in relation to postpartum death in piglets. The aim of this study was to evaluate the impact of the placental area and placental weight, status of the umbilical cord, and piglet birth characteristics, such as blood parameters, vitality score, and birth weight on postpartum death. All live born piglets in litters from 26 Landrace-Yorkshire sows were monitored during farrowing and the status of each was recorded, including placental area and placental weight and blood variables obtained from the piglets and umbilical veins. Out of the 386 live-born piglets, 16.8% died before weaning at 5 wk. Among these, 78.5% died within the first 3 d of life. Mean blood concentration of lactate was increased in piglets that did not survive to weaning (P = 0.003). Concentrations of hemoglobin and hematocrit were decreased (P Piglets born with a broken umbilical cord had a reduced vitality score vs. piglets born with an intact umbilical cord (P = 0.021), and they had an increased probability of dying before weaning (P = 0.050). Mean birth weight, body mass index, placental area (P piglets that died before weaning vs. those that survived. Birth weight and placental area were furthermore negatively associated with live litter size. Blood concentrations of IgG and albumin recorded at d 1 were decreased in piglets that died before weaning (P < 0.01), and blood concentration of albumin was positively associated with placental area (P < 0.001). We conclude that placental area and placental weight, status of the umbilical cord, birth weight, body mass index, blood concentrations of lactate, hemoglobin, and hematocrit recorded at birth, and blood concentrations of IgG and albumin recorded at d 1 were associated with postpartum death in this study

The majority of such cases are associated with primary gastrointestinal and gynecologic malignancies, and fewer cases are noted to derive from the thoracic cavity and the urinary tract. In this report, we describe a rare case of metastasis that presented as incarcerated umbilical hernia with no primary sites found. Extensive work-up, including tumor markers, imaging studies, endoscopies, and immunohistochemical analysis, failed to identify the primary source of this malignancy; this was a rare case of Sister Mary Joseph’s nodule with unknown primary. Therefore, it is very important for a surgeon to consider metastasis among the differential diagnosis of umbilical hernia.Keywords: umbilical metastasis, Sister Mary Joseph’s Nodule, hernia

    Full Text Available En este articulo se examinan las relaciones y diferencias entre el concepto de 'capital humano' y el concepto de 'capacidad humana'. El concepto de capital humano es mas limitado puesto que solo concibe las cualidades humanas en su relación con el crecimiento económico mientras que el concepto de capacidades da énfasis a la expansión de libertad humana para vivir el tipo de vida que la gente considera valedera. Cuando se adopta esa visión mas amplia, el proceso de desarrollo no puede verse simplemente como un incremento del PIB sino como la expansión de la capacidad humana para llevar una vida mas libre y mas digna.In this article the relationships and the differences between the concept of 'human capital' and the concept of 'human capability' are examined. The concept of human capital is more limited since it only conceives human qualities in relation to economic growth, whereas the concept of capabili ties puts emphasis on the expansion of human freedom to live the kind of life that people judge valuable. Whenthis broader vision is adopted, the process of development cannot be seen as simply an increase in the GNP, but rather as the expansion of the human capability to live a more free and worthy life.

    Full Text Available Background: Huge umbilical hernias (HUH are voluminous umbilical hernia (UH that are frequent in black African children. Several surgical techniques are used in their treatment for umbilical reconstruction, but techniques using skin flaps provide better aesthetic results. In this study, we presented our technique of umbilicoplasty in HUH, and its results. Patients and Methods: It is a retrospective study on children treated for HUH, from January 2012 to December 2013. The UH was called HUH when its basis diameter (BD exceeds 3 cm. Every HUH was characterised by its height, BD and morphology. Our technique was a two lateral flaps technique; the flaps are symmetrical and drawn so as to reconstitute the different parts of the umbilicus. The results were appreciated with criteria, including the peripheral ring and the central depression of the neo-umbilicus. Results : Twelve children were concerned (7 boys and 5 girls. Their mean age was 5 years and 6 months. The mean BD was 5.6 cm (extremes 3 and 8 cm, and the mean height of the HUH was 7.45 cm (extremes 3 and 9 cm. All underwent umbilicoplasty. In early post-operative period, two children presented a transitory subcutaneous hematoma. Late complications were granulation tissue with two children, and cheloid scar with one. With a mean follow-up of 10 months, we had 10 excellent results and two fair results according to our criteria. Conclusion: Our two lateral flaps umbilicoplasty is well-adapted to HUH in children. It is simple and assures a satisfactory anatomical and cosmetic result.

    Umbilical cord blood is an alternative hematopoietic stem cell source for patients with hematologic diseases who can be cured by allogeneic hematopoietic cell transplantation. Initially, umbilical cord blood transplantation was limited to children, given the low cell dose infused. Both related and unrelated cord blood transplants have been performed with high rates of success for a variety of hematologic disorders and metabolic storage diseases in the pediatric setting. The results for adult umbilical cord blood transplantation have improved, with greater emphasis on cord blood units of sufficient cell dose and human leukocyte antigen match and with the use of double umbilical cord blood units and improved supportive care techniques. Cord blood expansion trials have recently shown improvement in time to engraftment. Umbilical cord blood is being compared with other graft sources in both retrospective and prospective trials. The growth of the field over the last 25 years and the plans for future exploration are discussed.

    Full Text Available Interest in umbilical cord blood as an alternative source of hematopietic stem cells is growing rapidly. Umbilical cord blood offers the clinician a source of hematopoietic stem cells that are readily available and rarely contaminated by latent viruses. Moreover, the collection of umbilical cord blood poses no risk to the donor. There is no need for general anesthesia or blood replacement and the procedure causes no discomfort. Current clinical experience suggests that the incidence of GVHD in umbilical cord blood transplantation is low. These results and associated laboratory findings pose intriguing possibilities for the future of umbilical cord blood stem cells in the setting of unrelated donor transplantation. There are other intriguing possibilities for example cord blood may be an optimal source of pluripotential stem cells for use in genetherapy.

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para seg- mentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El al- goritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1. Los proce- samientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2. Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la es- tenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el con- curso Carotid Lumen Segmentation and Stenosis Grading Grand Challenge 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80,4% comparado con la segmentación de referencia, y el error promedio de la cuantifi- cación de estenosis fue 14,4%.

Se caracteriza por la compresión extrínseca de la arteria poplítea, ya sea por defecto anatómico de las estructuras músculo-tendinosas o por hipertrofia de los músculos gemelos, lo cual ocasiona el atrapamiento y síntomas de parestesias, frialdad y claudicación intermitente en la extremidad comprometida. La compresión crónica de la arteria puede llevar a daño irreversible con formación de trombos y aneurismas y a la consiguiente amputación de la extremidad, por lo que el diagnóstico y el tratamiento oportunos son de gran importancia para el paciente.The true prevalence of the popliteal artery entrapment syndrome is unknown, it is estimated to be 0.16%. It is considered as the main cause of intermittent claudication in young athletes without cardiovascular risk factors. It is characterized by the extrinsic compression of the popliteal artery either caused by defects of the muscle-tendon structures or by the hypertrophy of the gastrocnemius muscle leading to the arterial entrapment and symptoms of paresthesia, intermittent claudication and coldness of the affected limb. Chronic compression of the artery may lead to irreversible damage with formation of thrombi and aneurysms and the subsequent amputation of the limb. Therefore, correct diagnosis and treatment are of great importance for the patient.

  2. Evaluation of methods to test chemicals suitability for umbilical applications

    2006-03-15

    Offshore deep-water projects are increasingly deploying chemicals to sub-sea wellheads through umbilical lines. There is no margin for error in umbilical chemical treatment programs since any flow blockage in a sub-sea line would result in a multi-million dollar problem. Chemicals for umbilical delivery must also meet strict requirements in their performance and especially their handling properties. Umbilical delivery must be effective at low concentrations in preventing corrosion, scale, hydrates, asphaltenes, paraffin and a host of other problems. Chemical transiting an umbilical can experience pressures as high as 15,000 psi and temperatures ranging from near 0 deg C to greater than 120 deg C. Since some umbilicals are as long as 80 km, a week or more can elapse from the time the chemical is injected at the platform until it reaches the sub-sea well. Therefore, the chemical must not only be stable under all temperature and pressure conditions that it may experience in the umbilical line, it must also be stable under these conditions for a long period of time. Since many umbilical lines actually terminate into sub-sea valves and connectors that are only a few hundred microns in diameter, it is critical that the injected chemical have a low viscosity at sub-sea temperatures and pressures and that it be completely free of particles. These issues present substantial challenges in formulating and manufacturing chemicals for umbilical applications that must be addressed prior to approval of a product for use. Each of these challenges was taken into consideration and a series of tests were developed to assure reliable chemical pump ability through an umbilical line. The tests developed included enhanced formulation stability tests under umbilical temperature and pressure conditions, NAS Class rating, extensive material compatibility testing to include all metals and elastomers that may be used in umbilical injection systems and comprehensive physical property testing

    For Riemannian submanifolds of a semi-Riemannian manifold, we introduce the concepts of \\emph{total shear tensor} and \\emph{shear operators} as the trace-free part of the corresponding second fundamental form and shape operators. The relationship between these quantities and the umbilical properties of the submanifold is shown. Several novel notions of umbilical submanifolds are then considered along with the classical concepts of totally umbilical and pseudo-umbilical submanifolds. Then we focus on the case of co-dimension $2$, and we present necessary and sufficient conditions for the submanifold to be umbilical with respect to a normal direction. Moreover, we prove that the umbilical direction, if it exists, is unique ---unless the submanifold is totally umbilical--- and we give a formula to compute it explicitly. When the ambient manifold is Lorentzian we also provide a way of determining its causal character. We end the paper by illustrating our results on the Lorentzian geometry of the Kerr black hole.

    A 44-year-old female was initially evaluated for a 3-cm umbilical hernia, which developed after a laparoscopic myomectomy performed seven years prior. The umbilical hernia was repaired using a synthetic mesh. Eight months after the umbilical hernia repair, the patient returned with chronic pain in a 3-cm raised mass originating from the umbilical hernia repair incision. The mass and mesh were surgically removed. The umbilical fascial defect was repaired with a primary fascia-to-fascia closure and the umbilicus was reconstructed from adjacent skin. The mass was found histologically to be endometriosis and fascial scarring with a foreign body reaction to synthetic mesh. Umbilical endometriosis developed either from peritoneal endometrial seeding from a laparoscopic myomectomy or from metaplasia of multipotential cells, which developed into endometriosis due to inflammatory stimulation by the synthetic mesh. Synthetic mesh probably should be avoided in the surgical repair of a laparoscopically caused umbilical hernia in a premenopausal female especially if there is a history of pelvic endometriosis.

    Abstract Background: Umbilical cord hemangioma is very rare and may not be detected prenatally. However, it should be considered in differential diagnosis with other umbilical masses because it can cause significant morbidity. Methods: We report the case of a newborn referred with suspected omphalitis and umbilical hernia. Results: Physical examination showed an irreducible umbilical tumor, the size of olive, with dubious secretion. The initial suspected diagnosis was urachal or omphalomesenteric duct remnants. Abdominal ultrasound and magnetic resonance imaging showed an umbilical and a mesenteric mass. Tumor markers were negative. A definitive diagnosis of umbilical cord and intestinal hemangioma was established after surgical excision and histologic examination of the umbilical mass. Propranolol was prescribed due to the extent of the intestinal lesion. Conclusion: This report highlights the diagnostic challenges of hemangiomas in unusual locations. Apart from the rarity of these tumors, few tests are available to guide diagnosis, and surgery and histologic examination are generally required for a definitive diagnosis. Finally, it is essential to rule out associated malformations and hemangiomas in other locations. PMID:27759656

    The umbilicus is the main access route to the abdominal cavity in laparoscopic surgeries. However, its anatomical configuration is rarely studied in the surgical and anatomical literature. With introduction of laparoendoscopic single-site surgery and considering the significant number of primary and postoperative umbilical hernias, we felt the necessity to comprehensively study the umbilical structures and analyze their protective function against hernias. Twenty-four embalmed cadavers were studied in the anatomy laboratory of Case Western Reserve University. Round hepatic, median and medial ligaments, umbilical ring, umbilical and umbilicovesicular fasciae, and pattern of attachment to the ring were dissected and measured. Mean age was 82.1 years, ranging between 56 and 96 years, with a male-to-female ratio of 1.4:1. Ninety-two per cent was white and 8 per cent black adults. According to shape and attachment pattern of ligaments, umbilical ring is classified into five types. Hernia incidence was 25 per cent. All hernia cases lacked the umbilical fascia and the round hepatic ligament was not attached to the inferior border of the ring. The umbilical ring and its morphologic relation with adjacent ligaments are described and classified into five types. In contrary to sparse existing literature, we propose that umbilical fascia is continuation and condensation of umbilicovesicular rather than transversalis fascia. It was absent in cadavers forming conjoined median and medial ligaments with a single insertion site to the ring. Round ligament insertion to the inferior border of the ring provides another protective factor. These two protective measures were absent in all the observed umbilical hernias.

    Umbilical disorders, including omphalophlebitis, omphaloarteritis, external umbilical abscesses, urachal abscesses, patent urachus, and umbilical hernias, represent a significant challenge to the health and well-being of a neonate. The three neonatal giraffe (Giraffa camelopardalis) in this report were evaluated for umbilical swellings. Two developed omphalophlebitis, and one had an uncomplicated umbilical hernia. Omphalophlebitis is an inflammation and/or infection of the umbilical vein. Giraffe calves with a failure of passive transfer may be predisposed and should be thoroughly evaluated for the condition. Umbilical hernias result from a failure of the umbilical ring to close after parturition or from malformation of the umbilical ring during embryogenesis. These problems were surgically corrected for all three individuals, although one died due to postsurgical complications. The risks involved include anesthetic complications, surgical dehiscence, and maternal rejection. Early detection and surgical intervention are recommended for the correction of omphalophlebitis and umbilical hernias in neonatal giraffe.

    To determine normal umbilical circulation patterns by means of Doppler ultrasound scan in a healthy gestating population without risk factors and with normal perinatal results, and to evaluate any occurring modifications relative to gestational age by obtaining records kept during pregnancy. One hundred and sixteen pregnant women carrying a single fetus have been studied. These women had no risk factors, with both clinical and analytical controls, as well as ultrasound scans, all being normal. There were performed a total of 193 Doppler ultrasound scans between weeks 15 and 41 of gestation, with blood-flow analysis in the arteries and vein of the umbilical cord. The obtained information was correlated with parameters that evaluate fetal well-being (fetal monitoring and/or oxytocin test) and perinatal result (delivery type, birth weight, Apgar score). Statistical analysis was performed with the programs SPSS 6.0.1 for Windows and EPIINFO 6.0.4. With pulsed Doppler, the umbilical artery in all cases demonstrated a biphasic morphology with systolic and diastolic components and without retrograde blood flow. As the gestation period increased, there was observed a progressive decrease in resistance along with an increase in blood-flow velocity during the diastolic phase. The Doppler ultrasound scan is a non-invasive method that permits the hemodynamic study of umbilical blood circulation. A knowledge of normal blood-flow signal morphology, as well as of the normal values for Doppler indices in relation to gestational age would permit us to utilize this method in high-risk pregnancies.

    Tensile stiffness of ocean dynamic power umbilical is an important design parameter for functional implementation and structural safety. A column with radial stiffness which is wound by helical steel wires is constructed to predict the tensile stiffness value of umbilicals in the paper. The relationship between the tension and axial deformation is expressed analytically so the radial contraction of the column is achieved in the relationship by use of a simple finite element method. With an agreement between the theoretical prediction and the tension test results, the method is proved to be simple and efficient for the estimation of tensile stiffness of the ocean dynamic power umbilical.

Dos casos paradigmáticos sirven para abrir y cerrar el texto. En ellos se muestra, de manera contundente, el impacto de las actividades hermenéuticas sobre la configuración de nuevos sentidos, el cambio en las maneras de mirar y el acceso a nuevas formas de vida en el universo social. En el intermedio, el autor describe el progresivo distanciamiento de las ciencias humanas respecto al paradigma positivista. Se detiene en la conceptualización de cuatro categorías fundamentales de la actividad hermenéutica: la comprensión, la explicación, la interpretación y la traducción. Sostiene que la traducción del comprender es la tarea complementaria de la comprensión del comprender, e incorpora la propuesta de Paul Ricoeur para una nueva comprensión de la explicación en este ámbito. Finalmente, argumenta que la autocomprensión y la autovaloración de las ciencias humanas dependen de su capacidad reflexiva para considerar sus teorías y sus prácticas como textos susceptibles de autoexamen.

La metodología de análisis consiste en revisar el carácter de la realidad humana desde la noología, esto es, la última etapa de la obra del autor, a fin de presentar al hombre desde su dimensión eminentemente física y siempre encarnada de la realidad humana, permitiendo repensar desde una perspectiva física el desarrollo individual, así como también, el despliegue social e histórico del ser humano.

    Full Text Available A frequente utilização de sangue de cordão umbilical - SCU como fonte de células- tronco hematopoéticas - CTH, tanto em crianças, como em adultos, que não dispõem de doador na família, tem levado ao estabelecimento da padronização de critérios em sua seleção, objetivando a obtenção de melhores resultados. A escolha da unidade de SCU deve basear-se no número total de células nucleadas e no número de diferenças de antígenos leucocitários humanos (HLA. Diante de uma unidade com celularidade mínima, deve-se considerar a possibilidade da utilização de duplo cordão. Frente a mais de uma unidade com características semelhantes, a realização da contagem de células CD34 e da compatibilidade ABO, assim como a qualidade e a rapidez para obtenção da unidade, podem definir a escolha.The frequent use of umbilical cord blood as the source of hematopoietic stem cells, both in children and adults who do not have related donors, has led to the establishment of a better standardization of selection criteria aiming at improving the results. The choice of the umbilical cord blood unit should be based on the total number of nucleated cells and the number of differences in the human leukocyte antigen (HLA system. When a unit has minimal cellularity, the use of a double cord blood transplant should be considered. When two or more units have similar characteristics, the choice may be determined by the CD34 count, ABO compatibility and the quality and speed to obtain the unit.

    Full Text Available Hepatic artery aneurysms are scarcely reported, mainly because of non-specific symptoms. More often, they are incidental findings during imaging studies to investigate other acute or chronic abdominal conditions. These aneurysms are usually detected in the sixth decade of life, predominantly among males. We report the case of a 69 year-old female with an unsuspected huge hepatic artery aneurysm associated with ischemic hepatitis. Suspicion of aneurysm arose during imaging studies to clarify the origin of jaundice and abdominal pain. After establishment of the diagnosis, but before open surgery, there was a spontaneous rupture of the aneurysm, which caused hemoperitoneum and death. The necropsy study confirmed ischemic hepatitis. Hepatic artery aneurysms are second among the visceral aneurysms, and may cause abdominal pain, jaundice, and hemorrhagic events. One should suspect abdominal aneurysms in elderly patients with unclear abdominal pain, and this hypothesis should be ruled out by imaging studies.La publicación de trabajos sobre aneurismas en la arteria hepática es escasa, debido a los síntomas no específicos y a que constituyen hallazgos incidentales durante investigación de otras condiciones abdominales agudas o crónicas. Estos aneurismas son más frecuentes en varones y en la sexta década de la vida. Presentamos el caso de una mujer de 69 años de edad que ingresa en el hospital con un aneurisma de arteria hepática no sospechado previamente, asociado con hepatitis isquémica. La sospecha de aneurisma empezó durante estudio de imágenes para aclaramiento del origen de ictericia y dolor abdominal. Después de confirmado el diagnóstico, pero antes de la operación planeada, ocurrió rotura espontánea del aneurisma causando hemoperitoneo y muerte. El estudio de necropsia confirmó hepatitis isquémica. Los aneurismas de la arteria hepática son los segundos entre los aneurismas viscerales y pueden causar dolor abdominal, ictericia

    2008-01-01

    Single umbilical artery (SUA) is a relatively common malformation that may call attention to the possibility of associated malformations (often chromosome aberrations). The current study aimed at surveying malformations associated with SUA on the basis of fetopathological investigations, analyzing the role of history, summarizing the clinically important factors emerging together with this malformation. In this study, we processed the details of 204 cases in which SUA was confirmed fetopathologically after miscarriage or induced abortion between 1990 and 2007. In our sample, SUA occurred in 7.38% of the cases. The history was positive in almost 30% of the cases. The majority of the cases had a positive obstetric and the minority of them a positive genetic history. The highest association of SUA with other malformations was found for craniospinal ones, but an association with cardiovascular malformations should also be mentioned. Regarding the individual types of malformation, SUA was most commonly associated with hydrocephalus, but Potter's sequence, trisomy 21, and atrioventricular septal defect also reached a higher rate in associated SUA. Previously published articles dealing with associated malformations found that urogenital malformations were most commonly associated with SUA. 'Itemizing' the different non-chromosomal malformations in association with SUA, we found that hydrocephalus, Potter's sequence, and atrioventricular septal defect were the most frequent malformations, while in earlier studies, the association with non-chromosomal malformations such as vertebral malformations, imperforated anus, cheilognathopalatoschisis, and renal agenesis occurred more frequently than usual.

    Full Text Available Objective. To evaluate the effect of maternal smoking during pregnancy on levels of umbilical cord erythropoietin. Methods. Erythropoietin levels were measured in umbilical cord sera of 60 newborns who were delivered vaginally at term. There were 20 (33% smoking and 40 (67% nonsmoking mothers. Results. Mean cord serum erythropoietin levels were significantly lower in the nonsmokers (nonsmokers, 24 ± 9 IU/L; smokers, 61 ± 46 IU/L; P<.001. There was a significant positive correlation between the number of cigarettes smoked per day and cord serum erythropoietin levels (r, 0.58; P≤.05. Conclusions. Smoking during pregnancy is associated with increased levels of umbilical cord erythropoietin at birth. This may indicate a risk of fetal hypoxia and growth restriction. Education and encouragement of cessation of smoking during pregnancy are important to avoid associated fetal and maternal morbidity and mortality.

  10. Isolation and culture of human umbilical vein endothelial cells (HUVEC).

    Science.gov (United States)

    Cheung, Ambrose L

    2007-02-01

    Human-derived endothelial cells can now be routinely harvested from human umbilical veins. Studies with human umbilical vein endothelial cells (HUVEC) have been conducted with cells from passage 2 to 5. It is now also possible to cryopreserve primary and early-passaged HUVEC for future propagation and for forwarding to an end user by express courier. Stored HUVEC have been stably retrieved even after several years. These retrieval techniques have facilitated the deployment of HUVEC for many studies, including those for homeostasis, inflammatory disorders, atherosclerosis, cancer, and microbial adhesion and invasion. In this unit, we will delineate the procedure for harvesting, propagation, and storage of HUVEC.

    The dielectric properties of freshly delivered human placenta, umbilical cord and amniotic fluid have been acquired at 37 deg. C and in the frequency range of 200 MHz-10 GHz. The experimental data were fitted to a Cole-Cole expression. The results show that dielectric properties of the umbilical cord are significantly higher than placenta due to the presence of high water content Wharton's jelly. The results also demonstrate large differences in the dielectric properties of amniotic and cerebrospinal fluids. The data presented can be used in numerical simulations of the exposure of pregnant women to electromagnetic fields. (note)

    Full Text Available Este artigo tematiza o desamparo vivenciado pela consciência ante a ausência de bases sólidas para seus anseios de felicidade e para suas representações simbólicas. Com esse propósito, toma como objeto de reflexão um dos ensaios filosóficos de Albert Camus, O mito de Sísifo, equacionando a possibilidade de uma ética que estilize a vida, sem que se minimize a dolorosa precariedade da existência humana. Posteriormente, em diálogo com alguns textos de M. Foucault, a reflexão procura estabelecer os vínculos possíveis entre a ética camusiana e a ética como uma estética da existência, tal como pensada entre os gregos antigos.

    Full Text Available La imagen esperanzadora que perfilaron no pocos intelectuales, políticos, banqueros y empresarios a partir del término de la guerra fría, del supuesto «fin de las ideologías» y de la idea de la «aldea global» se desvaneció bajo los trazos que la realidad fue delineando como signos de una creciente tendencia a la barbarie que pone en peligro la vida en el plantea y que lesiona, de muchas maneras y en muchos rincones de la tierra, la dignidad humana3. Ante este panorama, se ha vuelto insistente la pregunta respecto de si los procesos educativos escolares pueden contribuir en algo para oponerse a esa tendencia. La respuesta positiva a esta interrogante se ha traducido en diversos esfuerzos para desarrollar lo que se ha llamado «educación valoral», o «educación centrada en valores, esfuerzos que si bien difieren en el signo teórico e ideológico y en el tipo de estrategia aplicada, han estimulado la interlocución, la reflexión y el estudio sobre el tema. El presente trabajo tiene la intención de contribuir a ese debate teórico al aportar algunos elementos que sustentan la tesis de que una educación escolar centrada en valores ha de ser un proceso eminentemente formativo que tenga como horizonte axiológico la dignidad humana.

Se insertaron sondas Nelaton a través de las arterias coronarias y se les inyectó solución de látex y tinta china. Se determinó el diámetro y el punto de origen para la coronaria derecha, coronaria izquierda, interventricular paraconal y circunfleja. Se cuantificaron el número de ramas diagonales, marginales ventriculares izquierdas y postero laterales. Se determinó frecuencia de ramus intermedius y tipo de dominancia. Se realizó análisis estadístico con un error estándar del 5%, con el Epidat 3,1. Resultados: El 100% de los orígenes anatómicos de las arterias coronarias fueron normales. La dominancia mas frecuente fue la derecha, 73%. El promedio de número de ramas marginales izquierdas, diagonales y posterolaterales fue de 3. La frecuencia de ramus intermedius fue de 12%. El calculo de chi cuadrado de Pearson mostró significancia entre el ramus intermedius y número de ramas marginales izquierdas (p=0,0009. Conclusiones: Las características anatómicas de las arterias coronarias del cerdo son similares a las del humano. El ramus intermedius se comporta como una primera rama marginal izquierda y no como una primera rama diagonal como lo afirman algunos autores.

    2016-01-01

    Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment.

    Cirrhotic patients with umbilical hernia have an increased likelihood of complications following repair. The aim of this study was to assess the outcomes of elective umbilical hernia repair in cirrhotic patients. Fifty patients having uncomplicated umbilical hernia with a cirrhotic liver were studied prospectively. These patients divided into three groups' according to Child-Turcotte-Pugh (CTP) classification. After management of coagulopathy, correction of hypoalbuminaemia and electrolytes imbalance, and control of ascites, all patients underwent elective hernia repair under regional anesthesia. A comparison was made between the three groups as regard the size of the defect in the linea Alba, operative time, postoperative morbidity and mortality, length of hospital stay, time of return to daily life and postoperative changes in liver function tests (LFTs) in relation to the regional anesthesia applied. hernioplasty was done under spinal anesthesia in 13 patients (26%), under epidural anesthesia in 10 patients (20%), under intercostal nerve block in 7 patients (14%), and under local anesthesia in 20 patients (40%). There was an increased safety (less changes in LFTs) in cases done under local anesthesia and intercostal nerve block. The overall complications rate was 30%. There was an increased complications rate towards the decompensated cases. The differences in the mean length of hospital stay and mean time of return to daily life are statistically significant between the three groups. Umbilical hernia recurrence rate was 2% and no mortality was reported in the study groups.

    Umbilical swellings are commonly identified in calves and can be caused by hernia formation, infection of the remnants of umbilical vessels or a combination of both. Ninety-one cases with umbilical swellings were admitted to the Leahurst Farm Animal Practice (LFAP) between July 2004 and February 2012; 55 were simple hernias and 36 had associated infection. Eighty-seven cases underwent surgery of which 86 survived until discharge. Postoperative complications occurred in 65/86 animals (73 per cent). In 51 cases (81 per cent) this was classified as minor requiring no additional treatment. Placement of a prosthetic mesh was associated with a higher OR for developing severe postoperative complication when compared with those not receiving a mesh (OR=19.3; 95% CI 4.5 to 83.5). Long-term survival results were available for 49 animals, 22 of which were remaining in the herd with a median age of 1346 days (3.7 years). Of the 27 animals which had exited the herd, 16 were adult dairy cows, 7 were dairy heifers, 2 were beef animals and 2 exited at an unknown stage. Umbilical surgery in calves carries a good prognosis, although placement of a mesh increases the risk of complications occurring in the postoperative period.

    Full Text Available Con el desarrollo de los colgajos miocutáneos de recto abdominal (TRAM, el abdomen inferior ha sido reconocido como la principal área dadora de tejidos autólogos de alta calidad, especialmente útiles en reconstrucción mamaria. Más recientemente la habilidad para obtener componentes adiposocutáneos similares sin sacrificar el músculo recto ha revolucionado el campo de la Cirugía Reconstructiva. El advenimiento de los colgajos de perforantes ha permitido a los cirujanos plásticos lograr los mismos buenos resultados estéticos que con los colgajos miocutáneos tradicionales, pero con un considerable descenso en la morbilidad del área donante. Con los colgajos de perforantes de la arteria epigástrica inferior profunda (DIEP y de la arteria epigástrica inferior superficial (SIEA, los pacientes han incrementado sus opciones de reconstrucción. Este artículo revisa la anatomía quirúrgica de la pared abdominal relativa a los colgajos SIEA y DIEP. Se explican detalladamente los pasos principales para la preparación preoperatoria, la técnica quirúrgica y los cuidados postoperatorios. Se discuten las ventajas y desventajas y se presen- tan los trucos técnicos que pueden ayudar a mejorar el resultado final. Además se ilustran con ayuda de casos clínicos las indicaciones típicas y atípicas.Following the development of the transverse rectus abdominis myocutaneous (TRAM flap, the lower abdomen has been recognized as a prime source of high quality autogenous tissue, especially useful in breast reconstruction. More recently, the ability to harvest a similar adipocutaneous component without sacrifice of the rectus muscle has revolutionized the field of reconstructive surgery. The advent of perforator flaps has allowed plastic surgeons to achieve the same highly esthetic results as with the former myocutaneous flaps while significantly decreasing the donor site morbidity.

Se utilizaron como autores principales Cohen y Swerdlik (2006, Hogan (2004, Larsen y Buss (2005 y Shaughnessy, Zechmeister y Zechmeister (2007. La metodología fue descriptiva, de campo, diseño no experimental. La prueba se aplicó a 559 personas, 484 de sexo femenino y 75 de sexo masculino, con edades entre 17 a 47 años. El coeficiente de fiabilidad obtenido con el método de la división por mitades fue de 0,77 interpretado medio alto, lo cual indica que el test es fiable, es decir existe correlación entre las mitades y los ítemes de cada una de las partes de la prueba. La confiabilidad interobservadores, efectuada por tres evaluadores independientes, resultó en un coeficiente de 0.87 la cual se interpreta como alta. Para determinar la validez de la prueba se utilizó la de constructo, con el índice de consistencia interna, encontrándose un valor de 0,51, que indica poca relación entre los diferentes aspectos medidos por la prueba, lo cual demuestra heterogeneidad de estos elementos. Se construyó un baremo local y se obtuvieron las normas de interpretación para la población mencionada. Se concluye que el test de la figura humana tiene fiabilidad y validez, sus resultados son consistentes y el instrumento mide el constructo que se pretende medir, recomendándose la utilización de las normas obtenidas para la interpretación de resultados.

Se presenta el caso de un paciente con pseudo-aneurisma de tronco de la coronaria izquierda e infarto antero-apical del ventrículo izquierdo cinco años después de un paro cardíaco secundario a un traumatismo no penetrante de tórax. Se consideró entonces que la lesión no era pasible de corrección percutánea o quirúrgica por lo que se optó por tratamiento médico conservador. Una angiografía coronaria por tomografía computarizada multicorte realizada 10 años después del evento inicial mostró ausencia de progresión de la lesión.Coronary pseudo-aneurysm is an extremely rare entity. Its natural history is scarcely known and its treatment is controversial. We report a case of pseudo-aneurysm of the left main coronary artery associated with an antero-apical infarct of the left ventricle diagnosed five years after a cardiac arrest following a non-penetrating thoracic trauma. The patient was treated conservatively because percutaneous or surgical correction were not considered suitable for this lesion. A multidetector computed tomography coronary angiogram performed 10 years after the initial event showed no evidence of progression.

    Full Text Available Die perkutane transluminale Angioplastie (PTA mit nachfolgender Implantation von selbstexpandierbaren intravaskulären Stents ist mittlerweile eine etablierte Methode zur Behandlung von arteriosklerotischen Läsionen geworden. Nachfolgende septische Komplikationen dieses Eingriffes, manches Mal mit tödlichem Ausgang, sind in der Literatur beschrieben, gelten jedoch als sehr selten. Daher gibt es auch eine sehr kontroversielle Meinung über die prophylaktische Gabe von Antibiotika bei der Implantation von Stents. Wir beschreiben einen Patienten, dem ein gecoverter Stent in die Arteria femoralis superficialis sinistra implantiert wurde und bei dem sich nachfolgend ein Abszeß um den Stent entwickelte. Der Patient hatte weder vor der Stentimplantation eine prophylaktische, noch im Anschluß eine begleitende antibiotische Therapie erhalten. Nach Diagnose des Abszesses wurde der Patient antibiotisch massiv abgedeckt und konnte in zufriedenstellendem Allgemeinzustand nach Hause entlassen werde. Zu Hause jedoch setzte der Patient seine antibiotische Therapie ab. Daraufhin entwickelte der Patient Zeichen einer schweren Allgemeinsepsis mit einer Spondylodiscitis im Bereich von TH 12 und L1 mit prae- und paravertebraler Infiltration, so wie auch einen Abszeß im Bereich des linken Musculus psoas.

    Full Text Available Coronary artery anomaly is defined as any anatomical pattern that is apart from the normal element in regard to their origin, number, distribution and course. Through different mechanisms, it could be the cause of t thoracic pain, sudden death, myocardiopathy, syncope, myocardial infarction and ventricular fibrillation. These constitute a group of malformations which can be classified into, congenital, acquired and associated to other cardiac entities malformations. Due to the importance of this topic for cardiologists and specifically to pediatric cardiologists, this bibliographical revision about abnormalities classification is carried out.
    Se define como anomalía de las arterias coronarias a cualquier patrón anatómico que se aparte de lo normal en lo referente a su origen, número, distribución y trayecto. Mediante diferentes mecanismos, pueden ser la causa de dolor torácico, muerte súbita, miocardiopatía, síncope, infarto de miocardio y fibrilación ventricular. Constituyen un grupo de malformaciones que pueden clasificarse en: congénitas, adquiridas y asociadas a otras entidades cardiacas. Por la importancia que reviste para cardiólogos en general y sobre todo para cardiólogos pediatras, se realiza una revisión bibliográfica acerca de la clasificación de estas anomalías.

    Full Text Available El examen de las amenazas para la seguridad y el bienestar de las personas inherentes al concepto de seguridad humana exige ocuparse también de las consecuencias que la utilización de las altas tecnologías puedan ocasionar en relación con los conflictos armados actuales. De ahí que en este trabajo abordemos los cambios relevantes en la naturaleza y características de los nuevos conflictos armados provocados por la celeridad y amplitud en el empleo de altas tecnologías y su desigual distribución entre los beligerantes, tal y como muestran las llamadas guerras de coste cero, de cuarta generación o asimétricas, e incluso las híbridas. Asimismo, el desarrollo reciente de las capacidades militares cibernéticas, de los sistemas de armas autónomos y de los vehículos aéreos no tripulados plantea nuevos retos al Derecho Internacional Humanitario, aspectos contemplados en este estudio.

    2003-01-01

    Full Text Available Para la sociobióloga, el éxito reproductivo a sido desde el principio, la medida universal del valor adaptivo. La noción es muy discutible, considerando que se trata de una estimación individual, inapropiada a evaluar el valor selectivo de un (supuesto genotipo, pero a pesar de su inadecuación y de la simplificación de su evaluación en la mayoridad de los estudios, el éxito reproductivo permanezco una medida muy popular. En el caso de las poblaciones humanas, su medida tuvo que ser aun más simplificada para tomar en cuenta la larga extinción de las generaciones, hasta ser el número de descendientes sobreviviendo hasta madurez sexual. Sin embargo, su definición aun no logro de ser ni precisa ni satisfactoria y los últimos trabajos parecen indicar que así como el coeficiente de consanguinidad, su significado se revela en la profundidad de la sucesión de las generaciones.

    Full Text Available No hay que confundir la dignidad con las condiciones indignas en que puede encontrarse una persona por circunstancias exteriores o por la enfermedad. La persona paciente en situación terminal tiene dignidad humana, que exige ser respetada, no por ser paciente terminal, sino simplemente por ser persona. Pero es cierto que en situaciones terminales puede verse particularmente amenazada la dignidad. Sin embargo, no se debe deducir del criterio de respetar la dignidad la conclusión de prolongar la vida biológica a toda costa, sino la de garantizar la mejor calidad del vivir durante el proceso de morir y de acompañar dignamente a la persona que se aproxima a la muerte ayudándole a asumirla.Dignity should not be confused with the unbecoming conditions that a person can find himself in due to external situations or disease. The person/patient in a terminal situation has human dignity, which must be respected not because he/she is a terminal patient but simply because he/she is a person. But it is true that in terminal situations dignity can be particularly threatened. Nonetheless, one must not deduce from the criterion of respecting dignity the conclusion of prolonging biological life at all costs, but instead that of guaranteeing the best quality of living during the process of dying and of worthily accompanying the person who is approaching death by helping him to accept this.

    Full Text Available Abdominal wall hernia is common but reliable scientific data about its work relatedness is very limited and inconsistent. In this paper, a less common type of abdominal wall hernia in a 30 year old male worker is presented with recurrence after first surgery when he returned to work. In contrast with almost all kinds of hernia, a lifelong limitation for heavy lifting was recommended. It seems that contrary to popular belief, work relatedness of abdominal wall hernia is seriously doubtful, although conclusive evidences are not enough. It is preferable to make decisions cautiously for return to heavy duties of work after surgery of large umbilical, umbilical & epigastric or incisional hernia, while avoiding recommendations for long days off work after surgery of any hernia.

    The use of thoracoscopy and laparoscopy in the treatment of congenital diaphragmatic hernias (CDHs) has been recently reported; however, the use of these procedures still remains controversial due to CO2 insufflation and limited working space. In addition, because of difficult techniques, it has not been widely accepted. Among CDH patients, mild cases whose lung is not hypoplastic, and not associated with persistent pulmonary hypertension of the neonate (PPHN) often develop small defects in the diaphragm that can be repaired using "direct closure." Because direct closure does not require as wide an operative field as that needed for patch closure, we repaired CDH through umbilical skin windows in two neonates with mild CDH to minimize the wounds. With the creation of additional radical small incisions, the surgeries were successfully performed without any intra- or postoperative complications, and the wounds were cosmetically pleasing. The repair of CDHs through umbilical skin windows is a feasible and useful approach in neonates with mild CDH.

    1998-01-01

    Here we described a critical analysis of the neonatological procedure of early cord clamping, meaning this, within 40 seconds after birth. Fifty three cases are here analysed, in which this practice was not performed, but instead a late umbilical cord clamping was done after birth or after the cord had stopped beating. Variations in hematocrito values within 24 to 36 hours after birth were studied. A transitory polycithemia, with a maximum peak 12 hours post-delivery was observed. These values returned to normal levels between 24 and 36 hours after birth. K vitamin was not administered to any of the newborns. No pathology appeared related to this transitory polycithemia. In can be concluded that the late umbilical cord clamping represents no risk to the new-born and that the pathological phenomena described under these circumstances may be attributed to the increase in K vitamin dependent coagulation factors that are induced by the routinary administration of phitonadione to all normal newborns.

    Quality of life (QOL) has become an important focus of hernia repair outcomes. This study aims to identify factors which lead to ideal outcomes (asymptomatic and without recurrence) in large umbilical hernias (defect size ≥9 cm(2)). Review of the prospective International Hernia Mesh Registry was performed. The Carolinas Comfort Scale was used to measure QOL at 1-, 6-, and 12-month follow-up. Demographics, operative details, complications, and QOL data were evaluated using standard statistical methods. Forty-four large umbilical hernia repairs were analyzed. Demographics included: average age 53.6 ± 12.0 and body mass index 34.9 ± 7.2 kg/m(2). The mean defect size was 21.7 ± 16.9 cm(2), and 72.7 per cent were performed laparoscopically. Complications included hematoma (2.3%), seroma (12.6%), and recurrence (9.1%). Follow-up and ideal outcomes were one month = 28.2 per cent, six months = 42.9 per cent, one year = 55.6 per cent. All patients who remained symptomatic at one and two years were significantly symptomatic before surgery. Symptomatic preoperative activity limitation was a significant predictor of nonideal outcomes at one year (P = 0.02). Symptomatic preoperative pain was associated with nonideal outcomes at one year, though the difference was not statistically significant (P = 0.06). Operative technique, mesh choice, and fixation technique did not impact recurrence or QOL. Repair of umbilical hernia with defects ≥9 cm(2) had a surprising low rate of ideal outcomes (asymptomatic and no recurrence). All patients with nonideal long-term outcomes had preoperative pain and activity limitations. These data may suggest that umbilical hernia should be repaired when they are small and asymptomatic.

  15. What has methylmercury in umbilical cords told us? - Minamata disease.

    Severe methylmercury poisoning occurred in Minamata and neighboring communities in the 1950s and 1960s. The exposed patients manifested neurological signs, and some patients exposed in utero were born with so-called congenital Minamata disease. In a previous report, Nishigaki and Harada evaluated the methylmercury concentrations in the umbilical cords of inhabitants and demonstrated that methylmercury actually passed through the placenta (Nishigaki and Harada, 1975). However, the report involved a limited number of cases (only 35) and did not quantitatively evaluate the regional differences in the transition of methylmercury exposure. Therefore, in the present study, we evaluated the temporal and spatial distributions of methylmercury concentrations in umbilical cords, with an increased number of participants and additional descriptive analyses. Then, we examined whether the methylmercury concentrations corresponded with the history of the Minamata disease incident. A total of 278 umbilical cord specimens collected after birth were obtained from babies born between 1925 and 1980 in four study areas exposed to methylmercury. Then, we conducted descriptive analyses, and drew scatterplots of the methylmercury concentrations of all the participants and separated by the areas. In the Minamata area, where the first patient was identified in 1956, the methylmercury concentration reached a peak around 1955. Subsequently, about 5 years later, the concentrations peaked in other exposed areas with the expected exposure distribution corresponding with acetaldehyde production (the origin of methylmercury). This historical incident several decades ago in Minamata and neighboring communities clearly shows that regional pollution affected the environment in utero. Furthermore, the temporal and spatial distributions of the methylmercury concentrations in the umbilical cords tell us the history of the Minamata disease incident.

    2015-01-01

    We experienced two cases involving the simultaneous presence of cholelithiasis, hiatal hernia, and umbilical hernia. Both patients were female and overweight (body mass index of 25.0-29.9 kg/m(2)) and had a history of pregnancy and surgical treatment of cholelithiasis. Additionally, both patients had two of the three conditions of Saint's triad. Based on analysis of the pathogenesis of these two cases, we consider that these four diseases (Saint's triad and umbilical hernia) are associated with one another. Obesity is a common risk factor for both umbilical hernia and Saint's triad. Female sex, older age, and a history of pregnancy are common risk factors for umbilical hernia and two of the three conditions of Saint's triad. Thus, umbilical hernia may readily develop with Saint's triad. Knowledge of this coincidence is important in the clinical setting. The concomitant occurrence of Saint's triad and umbilical hernia may be another clinical "tetralogy."

    Intrapartum death in multiparous gestations in sows (Sus scrofa) is often caused by hypoxia. There is little information in the literature on the assessment of the placenta in relation to intrapartum death in piglets. The aim of this study was to evaluate the impact of the placental area and weight upon piglet birth characteristics and intrapartum death. Litters from 26 Landrace-Yorkshire sows were monitored during farrowing and the status of each piglet was recorded, including blood parameters of piglets and their umbilical veins. Of 413 piglets born, 6.5% were stillborn.

Blood concentrations of lactate, hemoglobin, and hematocrit recorded in all piglets pooled were associated with placental area (P 0.2). Piglet BW was positively correlated with placental area and placental weight (P piglet birth weight, but not with the probability of being born dead. Placental area was a better predictor of piglet vitality than placental weight. Because umbilical cord rupture and prolonged birth time were associated with being born dead, umbilical cord rupture and placental detachment seem to be probable causes of intrapartum death.

    Hydatid cyst caused by Echinococcus granulosus demonstrates an endemic infection in several countries such as Middle Eastern countries. Liver is the most frequently involved organ, followed by the lung. The case we present is solitary primary localization of cyst in abdominal wall which is extremely rare. A 57-year-old woman presented with an abdominal wall lesion in umbilical area that had been evolving for about 2 years with recent complaint of pain and discomfort. We detected a midline abdominal mass 12⁎13 centimeters in diameter which was bulged out in umbilicus. Preoperative clinical diagnosis of incarcerated umbilical hernia was made due to its physical examination while surgical exploration disproved the primary diagnosis and we found cystic mass adherent to superficial fascia without any communication to peritoneal space. The cyst was excised completely without any injury or perforation of containing capsule. The diagnosis of hydatid cyst was confirmed by histopathological examination of specimen. The retrograde evaluation showed no involvement of other organs. The patient was followed for two years and no recurrence of hydatid disease has been observed. Hydatid cyst should be considered as a differential diagnosis of abdominal wall and umbilical lesions especially in endemic regions.

    The urachal cyst is a rare clinical entity of a urachal remnant. It is usually asymptomatic but can present with haematuria, tumour, urachal stone and infection. We present a case of a 63-year-old lady with a body mass index (BMI) of 49 who presented with a painful swelling in the umbilical region associated with an umbilical hernia. An ultrasound and computed tomography (CT) scan showed a suspected herniation of an umbilical remnant cyst through a paraumbilical defect. Laparoscopy confirmed the urachal cyst of 3 cm in size with a band connected with the cyst down to the urinary bladder associated with a 3-cm paraumbilical hernia. We removed the cyst and repaired the hernia laparoscopically uneventfully, after which her recovery was perfect. Radiological and laparoscopic pictures have not been reported in the English literature before. Although this condition is very rare, we suggest that it should be considered in the differential diagnosis of painful paraumbilical swelling. CT scanning and laparoscopy seems to be valuable, especially in obese patients.

    Umbilical hernias are a common occurrence in domestic animals and humans but have not been well documented in polar bears. Surgical reduction and herniorrhaphies were performed to correct acquired hernias in the region of the umbilicus in four adult captive polar bears (Ursus maritimus) housed in North American zoos. Two of the four bears were clinically unaffected by their hernias prior to surgery. One bear showed signs of severe discomfort following acute enlargement of the hernia. In another bear, re-herniation led to acute abdominal pain due to gastric entrapment and strangulation. The hernias in three bears were surgically repaired by debridement of the hernia ring and direct apposition of the abdominal wall, while the large defect in the most severely affected bear was closed using polypropylene mesh to prevent excessive tension. The cases in this series demonstrate that while small hernias may remain clinically inconsequential for long periods of time, enlargement or recurrence of the defect can lead to incarceration and acute abdominal crisis. Umbilical herniation has not been reported in free-ranging polar bears, and it is suspected that factors such as body condition, limited exercise, or enclosure design potentially contribute to the development of umbilical hernias in captive polar bears.

    Full Text Available Abstract Objective: to identify the factors related to the quality of umbilical cord and placental blood specimens, and define best practices for their collection in a government bank of umbilical cord and placental blood. Method: this was a descriptive study, quantitative approach, performed at a government umbilical cord and placental blood bank, in two steps: 1 verification of the obstetric, neonatal and operational factors, using a specific tool for gathering data as non-participant observers; 2 definition of best practices by grouping non-conformities observed before, during and after blood collection. The data was analyzed using descriptive statistics and the following statistical software: Statistica(r and R(r. Results: while there was a correlation with obstetrical and neonatal factors, there was a larger correlation with operational factors, resulting in the need to adjust the professional practices of the nursing staff and obstetrical team involved in collecting this type of blood. Based on these non-conformities we defined best practices for nurses before, during and after blood collection. Conclusion: the best practices defined in this study are an important management tool for the work of nurses in obtaining blood specimens of high cell quality.

    Full Text Available La aparición de nuevas técnicas de secuenciación así como el desarrollo de herramientas bioinformáticas han permitido no sólo describir la composición de la comunidad bacteriana que habita el tracto gastrointestinal, sino también las funciones metabólicas de las que proveen al huésped. La mayoría de los miembros de esta amplia comunidad bacteriana pertenecen a Dominio Bacteria, aunque encontramos también Archaea y formas eucariotas y virus. Únicamente entre 7 y 9 de las 55 Phyla del Dominio Bacteria conocidos están presentes en flora fecal humana. Su mayoría pertenecen además a las Divisiones Bacteroidetes and Firmicutes, encontrando también Proteobacteria, Actinobacteria, Fusobacteria y Verrucomicrobia. Bacteroides, Faecalibacterium y Bifidobacterium son los Géneros más abundantes aunque su abundancia relativa es muy variable entre individuos. El análisis metagenómico de la flora intestinal ha permitido describir una colección de 5 millones de genes microbianos que codifican para aproximadamente 20.000 funciones biológicas relacionadas con la vida de las bacterias. El ecosistema intestinal humano puede clasificarse en torno a tres grupos de acuerdo a la abundancia relativa de tres Géneros: Bacteroides (enterotipo 1, Prevotella (enterotipo 2 y Ruminococcus (enterotype 3. Estos grupos han sido denominados "enterotipos" y su descripción sugiere que las variaciones entre individuos están estratificadas. Una vez descrita la composición bacteriana sería interesante establecer la relación entre la alteración de equilibrios ecológicos con estados de enfermedad que puedan desembocar en una novedosa vía terapéutica.

    We report a rare complication of incarceration of an umbilical hernia after Denver peritoneovenous shunt placement. A 50-year-old man presented with refractory ascites from liver cirrhosis. He also had an umbilical hernia. Because the ascites became uncontrollable, Denver peritoneovenous shunting was performed. The operation was successful and the ascites decreased. Ten days later, however, incarceration of the umbilical hernia occurred. A surgical repair was performed, but he died 2 days later. The cause of death was considered to be sepsis.

    A large umbilical protrusion with redundant skin accompanying an umbilical hernia sometimes needs umbilicoplasty. Although several different techniques for making umbilical depression have been used, the results of the plastic surgery are sometimes unsatisfactory due to postoperative flattening or disappearance of the umbilical depression. To make a permanent umbilical depression that is cosmetically acceptable, we have modified the techniques. Umbilicoplasty was performed in 14 children whose ages ranged from 6 months-6 years and 3 months (median, 1 year and 10 months) and who had umbilical hernia with a large umbilical protrusion. After the fascial defect was closed, the diameter of the umbilicus was reduced to half that before surgery by removing fan-shaped skin flaps and approximating skin edges, and then inverting the umbilicus and fixing it caudally to the fascia and skin. There were no postoperative complications, and no flattening or disappearance of umbilical depression was observed during the follow-up of 10-19 months. The authors' technique of umbilicoplasty for a large protruding umbilicus accompanying umbilical hernia is a simple method that produces acceptable cosmetic results.

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para segmentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El algoritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1 Los procesamientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2 Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la estenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el concurso “Carotid Lumen Segmentation and Stenosis Grading Grand Challenge” 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80.4% comparado con la segmentación de referencia, y el error promedio de la cuantificación de estenosis fue 14.4%.

    Full Text Available É descrito um caso de adiaspiromicose humana, da forma pulmonar disseminada, no qual se empregou o cetoconazol. O paciente, oriundo de Goianésia, GO, referia tosse produtiva, dispnéia e emagrecimento. Doente há dois meses, já fizera uso do esquema tríplice tuberculostático, devido a um radiograma do tórax ter acusado lesões sugestivas de tuberculose miliar. Esse tratamento não surtiu o efeito esperado, pelo que foi ele submetido a uma biópsia pulmonar a céu aberto. A medida permitiu o reconhecimento da natureza fúngica da doença. Passou-se, então, ao emprego do cetoconazol, quando o processo já completara três meses de evolução. Dois meses depois, foi o paciente novamente visto, para controle do tratamento: todas as manifestações respiratórias haviam cessado e um novo radiograma mostrou regressão completa das alterações pulmonares. Apesar disso, é discutida a eficácia do cetoconazol contra C. parvum var crescens, tendo-se em conta o fato de o microrganismo não se reproduzir no hospedeiro.A case of human disseminated pulmonary adiaspiromycosis is reported. The patient, from Goianesia, GO, was admitted to the Brasilia University Hospital, in November 1992, with wet cough, dyspnea and weight loss3/4manifestations that had appeared two months before. Prior to admission, he had been treated for a suspected miliary tuberculosis, because a chest roentgenogram had shown a diffuse reticulonodular infiltrate in both lungs. This therapy brought no improvement to the patient status. An open chest biopsy was then performed, and the microscopic examination of the lung tissue revealed the fungal nature of the disease. Ketoconazole, 400mg/day, was started and the patient discharged from the hospital. He was seen again two months later: the respiratory manifestations had disappeared and a new chest roentgenogram showed complete resolution of the pulmonary lesions. The usefulness of ketoconazole is, however, questioned, since, as there

    El ser humano tiene dos vidas. Una física y otra humana. Ambas son diferentes pero están íntimamente relacionadas. La vida humana no es biológica, no es la persona de carne y huesos; no son los músculos ni la masa encefálica, ni los demás órganos que le dan existencia física. Su origen se encuentra en la organización de la sociedad, en las instituciones sociales, y entre ellas, la familia es clave fundamental.

    Alabed, Yazan Z; Sakellis, Christopher

    2015-10-01

    An 84-year-old man with history of left forehead melanoma was found on a restaging F-FDG PET/CT scan with hypermetabolic lung nodules and a mildly FDG-avid soft tissue nodule posterior to the umbilicus. Biopsy of a right lower lobe nodule revealed metastatic melanoma. Follow-up posttreatment PET/CT scan showed complete resolution of lung nodules and unchanged FDG uptake at the level of the umbilicus. Review of the patient's medical history revealed a remote history of umbilical hernia repair. We present a case of postsurgical plugoma mimicking the appearance of melanoma metastasis on FDG PET/CT.

    Full Text Available Background: Strangulated Meckel′s diverticulum (MD in an umbilical hernia (UH is a rare event. We present herein a case of strangulated MD in UH in a child. Case Report: An 18-month girl was admitted with clinical features suggesting upper intestinal strangulation since seven days. Many attempts of reduction were done before admission. She was resuscitated and had exploratory laparotomy, which revealed the hernia sac containing a completely gangrenous MD. She had bowel resection and had an uneventful postoperative period. Conclusion: An MD may be the content of a strangulated UH. Bowel resection of the segment bearing the diverticulum is advisable if the latter is gangrenous.

    2009-01-01

    Objective Developing a tissue-engineered small-diameter (<6 mm) vascular graft for reconstructive surgery has remained a challenge for the past several decades. This study was conducted to develop a decellularized umbilical artery and to evaluate its composition, endothelial cell compatibility, mechanical properties, and in vivo stability for potential use as a small-diameter vascular graft. Methods and Results Human umbilical arteries were isolated and decellularized by incubation in CHAPS and sodium dodecyl sulfate buffers followed by incubation in endothelial growth media-2. Decellularized umbilical arteries were completely devoid of cellular and nuclear material while retaining the integrity of extracellular collagenous matrix. The mechanical strength of the decellularized umbilical artery as assessed by its burst pressure in vitro showed no significant change from its native form. Decellularized umbilical arteries supported endothelial adherence as indicated by the re-endotheliazation with a monolayer of human umbilical vein endothelial cells. Furthermore, decellularized vessels that were implanted into nude rats as abdominal aorta interposition grafts remained mechanically intact and patent for up to 8 weeks. Conclusion Decellularized human umbilical arteries preserved the extracellular matrix, supported endothelialization, and retained function in vivo for up to 8 weeks. These properties suggest the potential use of decellularized umbilical arteries as small-diameter vascular grafts. PMID:19207043

    Full Text Available It is presented in this article analysis of two models of subsea umbilicals under axial stress. Subsea umbilicals play a crucial role in offshore petroleum production and are designed to withstand all the environmental dynamic loads during the production period as long as 25 years. Apart from dynamic loads subsea umbilicals are under thermal loads as well having impact on the structural components and changing the material properties in some cases. The cross-section arrangement is a major part of the entire process of subsea umbilicals design. That is why this research is focused on the design of cross-section and has an aim to calculate main impacts subsea umbilicals facing during exploitation.

    Spontaneous umbilical endometriosis occurring in absence of any previous abdominal or uterine surgery is extremely atypical. Its association with umbilical hernia is very rare and hernia getting spontaneously resolved has not been reported in literature so far. Here we report a case of a patient with spontaneous umbilical endometriosis associated with umbilical hernia which led to spontaneous hernia reduction. This was also associated with multiple uterine fibromyoma and bilateral ovarian endometrioma which were simultaneously treated by total abdominal hysterectomy with bilateral salpingo-oopherectomy along with surgical excision of the endometriotic tissue and repair of the abdominal wall defect. To the best of our knowledge, this is the first described case of spontaneous umbilical hernia reduction due to development of endometriosis.

    Cell-based therapy is a promising therapy for myocardial infarction. Endogenous repair of the heart muscle after myocardial infarction is a challenge because adult cardiomyocytes have a limited capacity to proliferate and replace damaged cells. Pre-clinical and clinical evidence has shown that cell based therapy may promote revascularization and replacement of damaged myocytes after myocardial infarction. Adult stem cells can be harvested from different sources including bone marrow, skeletal myoblast, and human umbilical cord blood cells. The use of these cells for the repair of myocardial infarction presents various advantages over other sources of stem cells. Among these are easy harvesting, unlimited differentiation capability, and robust angiogenic potential. In this review, we discuss the milestone findings and the most recent evidence demonstrating the therapeutic efficacy and safety of the transplantation of human umbilical cord blood cells as a stand-alone therapy or in combination with gene therapy, highlighting the importance of optimizing the timing, dose and delivery methods, and a better understanding of the mechanisms of action that will guide the clinical entry of this innovative treatment for ischemic disorders, specifically myocardial infarction.

    Acute umbilical hernia rupture in patients with hepatic cirrhosis and ascites is an unusual, but potentially life-threatening complication, with postoperative morbidity about 70% and mortality between 60%-80% after supportive care and 6%-20% after urgent surgical repair. Management options include primary surgical repair with or without concomitant portal venous system decompression for the control of the ascites. We present a retrospective analysis of our centre's experience over the last 6 years. Our cohort consisted of 11 consecutive patients (median age: 53 years, range: 36-63 years) with advanced hepatic cirrhosis and refractory ascites. Appropriate patient resuscitation and optimisation with intravenous fluids, prophylactic antibiotics and local measures was instituted. One failed attempt for conservative management was followed by a successful primary repair. In all cases, with one exception, a primary repair with non-absorbable Nylon, interrupted sutures, without mesh, was performed. The perioperative complication rate was 25% and the recurrence rate 8.3%. No mortality was recorded. Median length of hospital stay was 14 d (range: 4-31 d). Based on our experience, the management of ruptured umbilical hernias in patients with advanced hepatic cirrhosis and refractory ascites is feasible without the use of transjugular intrahepatic portosystemic shunt routinely in the preoperative period, provided that meticulous patient optimisation is performed.

    Full Text Available The research work objective was to examine the results of intraperitoneal plastics in the hernias of anterior abdominal wall. The experience of treatment of 89 patients with uncomplicated umbilical and postoperative ventral hernias was analized. The surgical treatment included an open intraperitoneal prosthetic hernioplasty. The hernial sac was not removed during the operation. The original techniques of treatment of hernia sac were used. Anatomical and morphological features in the structure of middle ventral hernias and their pathophysiological assessment were revealed. Practical recommendations for technology of intraperitoneal prosthesis were given. The early postoperative complications occurred: seroma (n=2, the outflow of serous fluid drainage for 5 days (n=1, infiltration of the umbilical area (n=3, suppuration of wounds (n=1. Vacuum drainage was performed in 24 patients after removal of large hernial defects. During the period from 6 months to 4 years recurrences were not revealed. The intraperitoneal surgery using a complex of musculo-aponeurotic tissues provided hernial implant fixation. Operation without the removal of the hernial sac reduced the trauma intervention. Method of suturing the surgical wound reduced the time of drainage and reduced the number of wound complications

    Adequate oxygenation is essential for normal embryogenesis and fetal growth. Perturbations in the intrauterine oxidative environment during pregnancy are associated with several pathophysiological disorders such as pregnancy loss, preeclampsia, and intrauterine growth restriction. We proposed to use optoacoustic technology for monitoring placental and fetal umbilical blood oxygenation. In this work, we studied optoacoustic monitoring of oxygenation in placenta and umbilical cord blood ex vivo using technique of placenta perfusion. We used a medical grade, nearinfrared, tunable, optoacoustic system developed and built for oxygenation monitoring in blood vessels and in tissues. First, we calibrated the system for cord blood oxygenation measurements by using a CO-Oximeter (gold standard). Then we performed validation in cord blood circulating through the catheters localized on the fetal side of an isolated placental lobule. Finally, the oxygenation measurements were performed in the perfused placental tissue. To increase or decrease blood oxygenation, we used infusion of a gas mixture of 95% O2 + 5% CO2 and 95% N2 + 5% CO2, respectively. In placental tissue, up to four cycles of changes in oxygenation were performed. The optoacoustically measured oxygenation in circulating cord blood and in placental lobule closely correlated with the actual oxygenation data measured by CO-Oximeter. We plan to further test the placental and cord blood oxygenation monitoring with optoacoustics in animal and clinical studies.

    Background Umbilical cord around neck,a common obstetric complication,affects fetal hemodynamics.Does it influence fetal cardiac functions? The purpose of this study was to investigate the left and right ventricular systolic and diastolic functions of fetuses with umbilical cord around neck in the third trimester by applying velocity vector imaging (VVI).Methods Thirty-five cases of fetuses with umbilical cord around neck whose gestational ages from 35 to 40 weeks were selected,including 20 cases of umbilical artery ratio of the highest systolic velocity (S) to the lowest diastolic velocity (D) (S/D) <3.0 and 15 cases of umbilical artery S/D ≥3.0,while 20 cases of normal fetuses of 35-40 gestational weeks were selected as the control group.The changes in longitudinal velocity,strain,and strain rate of fetal left and right ventricle in systole and diastole in two groups,and the changes in fetal cardiac function under the situation of umbilical cord around neck were analyzed.Results Longitudinal strain and strain rate overall of fetal left and right ventricle in systole and diastole were less in fetuses with umbilical artery S/D ≥3.0 and umbilical cord around neck than those in fetuses with umbilical artery S/D <3.0and those in control group (P <0.05); there was no significant difference (P >0.05) in longitudinal strain and strain rate overall of fetal left and right ventricle in systole and diastole between fetuses with umbilical artery S/D <3.0 and those in control group.Conclusions Left and right ventricular systolic and diastolic dysfunction was detected in fetuses with umbilical cord around neck and umbilical artery S/D ≥3.0.WI could sensitively respond to cardiac function changes in fetuses with umbilical cord around neck,which provides another valuable method in the evaluation of fetal cardiac function.

    The aim of the present study was to estimate the total number of mast cells in the human umbilical cord. Using 50 microns-thick paraffin sections, made from a systematic random sample of umbilical cord, the total number of mast cells per cord was estimated using a combination of the optical disector and fractionated sampling. The mast cell of the human umbilical cord was found in Wharton's jelly, most frequently in close proximity to the three blood vessels. No consistent pattern of variation in mast cell numbers from the fetal end of the umbilical cord towards the placenta was seen. The total number of mast cells found in the umbilical cord was 5,200,000 (median), range 2,800,000-16,800,000 (n = 7), that is 156,000 mast cells per gram umbilical cord (median), range 48,000-267,000. Thus, the umbilical cord constitutes an adequate source of mast cells for further investigation of these cells in the newborn, e.g. for describing their functional and secretory characteristics and possible clinical relevance in relation to the development of allergic, inflammatory and immunological diseases in infancy and childhood.

  15. Cell therapy of congenital corneal diseases with umbilical mesenchymal stem cells: lumican null mice.

    Full Text Available BACKGROUND: Keratoplasty is the most effective treatment for corneal blindness, but suboptimal medical conditions and lack of qualified medical personnel and donated cornea often prevent the performance of corneal transplantation in developing countries. Our study aims to develop alternative treatment regimens for congenital corneal diseases of genetic mutation. METHODOLOGY/PRINCIPAL FINDINGS: Human mesenchymal stem cells isolated from neonatal umbilical cords were transplanted to treat thin and cloudy corneas of lumican null mice. Transplantation of umbilical mesenchymal stem cells significantly improved corneal transparency and increased stromal thickness of lumican null mice, but human umbilical hematopoietic stem cells failed to do the same. Further studies revealed that collagen lamellae were re-organized in corneal stroma of lumican null mice after mesenchymal stem cell transplantation. Transplanted umbilical mesenchymal stem cells survived in the mouse corneal stroma for more than 3 months with little or no graft rejection. In addition, these cells assumed a keratocyte phenotype, e.g., dendritic morphology, quiescence, expression of keratocyte unique keratan sulfated keratocan and lumican, and CD34. Moreover, umbilical mesenchymal stem cell transplantation improved host keratocyte functions, which was verified by enhanced expression of keratocan and aldehyde dehydrogenase class 3A1 in lumican null mice. CONCLUSIONS/SIGNIFICANCE: Umbilical mesenchymal stem cell transplantation is a promising treatment for congenital corneal diseases involving keratocyte dysfunction. Unlike donated corneas, umbilical mesenchymal stem cells are easily isolated, expanded, stored, and can be quickly recovered from liquid nitrogen when a patient is in urgent need.

    Full Text Available Umbilical discharge in infancy is often attributed to infection or an umbilical granuloma. It is important to investigate if such a discharge is due to an underlying congenital abnormality because corrective surgical intervention may then be required. We present the first case of an infant with a persistent umbilical discharge from an omphalomesenteric duct cyst. The discharge was associated with periumbilical dermatitis. The dermatitis was most likely due to irritation of the skin by gastric acid produced by the ectopic gastric mucosa contained in the omphalomesenteric duct cyst. Both discharge and dermatitis resolved after surgical removal of the cyst.

    2013-09-01

    The timing of umbilical cord clamping remains controversial. Although most maternity wards use the early clamping (5-15s), randomized studies and meta-analyses have demonstrated the benefit of delayed clamping for term and preterm newborn infants over the past 10 years. Indeed, placentofetal transfusion of 20-30 ml/kg in 2-3 min improves the iron status of term infants and prevents infant hypochromic anemia. Infant anemia is a public health problem in many developing countries. For preterm newborns, placental transfusion for 45 s or milking the cord for 15 s improves cardiovascular adaptation, with better hemodynamic stability, as well as decreased intraventricular hemorrhages, need for transfusion, and late-onset sepsis. A new look at this symbolic act is needed and professionals need to be persuaded of the importance of the "wait a minute" policy for a better physiological delivery.

    Full Text Available In this article we analyze bioethical and legal aspects related to the cryopreservation of cord blood stem cells in Argentina. To unify definitions, the concept and variety of stem cells, together with the understanding of the means to obtain and store umbilical cord blood stem cells, are provided.  Options that arise in our country, mainly analyzing the conceptual differences underlying legal body and parts by public and private biobanks, are described. Additionally, the current Argentinean legislation and circumstances arising from a resolution which INCUCAI sought to regulate private biobanks, is analyzed. This analysis leads to thoughts on the way conflicts are solved when the health and life of people are judicialized. In this particular case, the appearance of a complex new topic which gives rise to new social and healthcare scenarios, must be further understood.

    Full Text Available This paper presents a 3-dimensional finite element formulation for predicting the behaviour of complex umbilical cross-sections exposed to loading from tension, torque, internal and external pressure including bending. Helically wound armours and tubes are treated as thin and slender beams formulated within the framework of small strains but large displacements, applying the principle of virtual displacements to obtain finite element equations. Interaction between structural elements is handled by 2- and 3-noded contact elements based on a penalty parameter formulation. The model takes into account a number of features, such as material nonlinearity, gap and friction between individual bodies, and contact with external structures and with a full 3-dimensional description. Numerical studies are presented to validate the model against another model as well as test data.

    Full Text Available Buffalo is an important livestock resource, with a great participation in agricultural systems, providing milk, meat, and work power. Umbilical cord is responsible for maternal-fetal nutrients exchange during pregnancy, and its alterations can compromise the fetal development. We investigated ten pregnant uteruses collected from cross-bread buffaloes in different stages of gestation. Pregnancy and fetal age was determined by measuring the apex sacral length and development period was calculated by previously published formula. Umbilical cords were measured for length determination. Umbilical cord vascular net and anastomosis were observed by injection of Neoprene latex. Histological sections of the umbilical cord were studied after stain with HE, picrossirius, toluidine blue, orceine, and PAS reaction. Buffaloes' umbilical cord was formed by two central arteries, an allantois duct and two peripheral veins. The artery wall was composed by large quantity of collagen, elastic fibers, fibroblasts and large number of vasa vasorum. The allantois duct was located between the arteries and presented a great number of small nourishing vessels. Small nourishing vessels should be carefully considered to avoid to be mistaken to the arterials and veins vasa vasorum. Medium length of umbilical cord from buffalos was 11.8cm (minimum of 6.8cm and maximum of 17.4cm.Búfalo é uma importante fonte de recurso nos rebanhos animais, apresentando uma grande participação na agropecuária, provendo leite, carne e força de trabalho.

    Umbilical cord mesenchymal stem cel s were isolated by a double enzyme digestion method. The third passage of umbilical cord mesenchymal stem cel s was induced with heparin and/or basic fi-broblast growth factor. Results confirmed that cel morphology did not change after induction with basic fibroblast growth factor alone. However, neuronal morphology was visible, and microtu-bule-associated protein-2 expression and acetylcholine levels increased fol owing induction with heparin alone or heparin combined with basic fibroblast growth factor. Hb9 and choline acetyl-transferase expression was high fol owing inductive with heparin combined with basic fibroblast growth factor. Results indicate that the inductive effect of basic fibroblast growth factor alone was not obvious. Heparin combined with basic fibroblast growth factor noticeably promoted the differen-tiation of umbilical cord mesenchymal stem cel s into motor neuron-like cel s. Simultaneously, um-bilical cord mesenchymal stem cel s could secrete acetylcholine.

    Concentrations of hypoxanthine (HX) was determined in umbilical venous blood and amniotic fluid obtained at 74 instances in 36 rhesus immunized patients before the onset of labor. HX concentrations were related to gestational age, concentrations of hemoglobin and lactate, pH, and partial oxygen pressure in umbilical venous blood. Multiple regression analysis revealed hemoglobin concentration to be the only variable that had any explanatory power to HX in amniotic fluid. No one of the studied variables gave any significant contribution to a regression model to explain HX in umbilical venous blood. We conclude that HX levels in umbilical venous blood and in amniotic fluid from rhesus immunized patients were not associated with fetal blood gases before the onset of labor.

    Many studies have drawn attention to the emerging role of MSC (mesenchymal stem cells) as a promising population supporting new clinical concepts in cellular therapy. However, the sources from which these cells can be isolated are still under discussion. Whereas BM (bone marrow) is presented as the main source of MSC, despite the invasive procedure related to this source, the possibility of isolating sufficient numbers of these cells from UCB (umbilical cord blood) remains controversial. Here, we present the results of experiments aimed at isolating MSC from UCB, BM and UCM (umbilical cord matrix) using different methods of isolation and various culture media that summarize the main procedures and criteria reported in the literature. Whereas isolation of MSC were successful from BM (10:10) and (UCM) (8:8), only one cord blood sample (1:15) gave rise to MSC using various culture media [DMEM (Dulbecco's modified Eagle's medium) +5% platelet lysate, DMEM+10% FBS (fetal bovine serum), DMEM+10% human UCB serum, MSCGM] and different isolation methods [plastic adherence of total MNC (mononuclear cells), CD3+/CD19+/CD14+/CD38+-depleted MNC and CD133+- or LNGFR+-enriched MNC]. MSC from UCM and BM were able to differentiate into adipocytes, osteocytes and hepatocytes. The expansion potential was highest for MSC from UCM. The two cell populations had CD90+/CD73+/CD105+ phenotype with the additional expression of SSEA4 and LNGFR for BM MSC. These results clearly exclude UCB from the list of MSC sources for clinical use and propose instead UCM as a rich, non-invasive and abundant source of MSC.

    This work had as objective to develop, to implant, to survey and to test an experimental and numerical model of structural, applicable analysis of umbilical structures. An ample study of the behavior of its constituent layers was carried through, in special of its nucleus and material constituents, when operating under different conditions of tensions and deformations. As support for this work, experimental tests for one type of electro-optic umbilical with typical transversal section had been carried through. This was made with the intention to optimize the developed numerical model. With this model of structural analysis, the project of umbilicals could highly improved, in terms of the total weight of the handle, which is one of the great problems for its use in great depths, with the maximum of efficiency and the minimum of losses, foreseeing and hindering operation imperfections that can come to occur due to extreme deformation or electric rupture of the layers, hoses or handles.

    Full Text Available : BACKGROUND: The umbilical cord usually shrivels and falls off at around 5 to 15days of life. It is important to know timing of separation, so that parents may be advised on proper cord care and ally any misconceptions about the cord separation; early discharge has increased the need for women to receive accurate, relevant information on how to care for themselves and their newborns when discharged from the hospital. Delay in separation of the umbilical cord, umbilical discharge, odor, or granuloma causes concern and source of immense anxiety for parents, the interval between delivery and umbilical cord separation varies worldwide, this study is undertaken to determine time of separation and factors influencing the separation. OBJECTIVES: To determine time of separation of umbilical cord and factors influencing it. METHODS: SETTINGS: Babies admitted at a tertiary hospital, selected by purposive sampling technique. For each recruited baby, data is obtained about mother's parity, mode of delivery, gestational age, birth weight, and gender of baby, method of resuscitation, phototherapy, IV antibiotics, and cord blood TSH values, time of umbilical cord separation after birth. Newborns whose umbilical cord shriveled off during the stay in the hospital information were obtained directly, and a self-addressed postcard was given to parents of newborns whose umbilical cord was intact at time of discharge. Parents would be advised to note and write the date of fall of umbilical cord on post card and mail it. RESULTS: Cord separation time ranges from 3 to 11 days, with mean separation of 5.62 ± 2.37 days, it is one to two days earlier as compared to previous studies, seventy nine (79 of hundred and ten (110 separated between 5-7 days (71%, one baby had separation at 11days, babies who received antibiotics had statistically significant delay in separation time of umbilical, neonates received antibiotics had mean separation time (6 ± 2.4 days as compared

    Full Text Available Cuando tu perro te ve, no sólo se iluminan sus ojos, también su cerebro. Aquí resumimos un experimento que realizamos para conocer el procesamiento cerebral de las caras humanas en perros, utilizando imágenes de resonancia magnética funcional, en el que encontramos actividad en la corteza temporal, frontal y el núcleo caudado. La actividad en la corteza temporal sugiere que los perros procesan las caras de manera similar a nosotros. Fue inesperado encontrar actividad en el núcleo caudado, porque sugiere que los perros procesan las caras humanas como recompensas, incluso si son caras de humanos desconocidos.

Entendemos o currículo de formação humana a partir da filosofia da práxis. Coadunando com nossas perspectivas epistemológicas, concordamos com a leitura de Semeraro (2001b, quando aponta que Gramsci melhor desvela o processo de elaboração da filosofia da práxis a partir de novas relações sociais; ou seja, desligado das puras abstrações, o filósofo italiano observa na “unidade das tensões dualistas e as contradições ricas e complexas” (“entre teoria/prática, intelectuais/massa, organização/espontaneidade, sociedade política/sociedade civil, ocidente/oriente, norte/sul, história do mundo/história particular”, a articulação para o desenvolvimento da atividade humana plena. A partir destes pressupostos colocados aqui enquanto premissas para a sistematização de nossos estudos, nos debruçaremos sobre dois grandes objetivos: (1 compreender o processo de humanização a partir da esfera das objetivações sociais e (2 a constituição do currículo de formação humana atrelado aos diferentes modos de produção, uma vez que demanda em diferentes formações sociais.

Su empleo promete beneficios para la humanidad y, específicamente para parejas infértiles la satisfacción de ser madres y padres. En este artículo se debaten las regulaciones y las implicaciones jurídicas de dicha actividad, actualizándonos en el acontecer mundial y nacional del tema. Se argumenta que la clonación humana ya es una realidad y como si esta técnica se regula promueve la vida y la dignidad humanas. Además se propone que esta técnica se entiende mejor no en términos moralistas, sino contextuales que responden a situaciones reales de la vida, específicamente una ética de la responsabilidad.The techniques of assisted reproduction, among them human cloning, rises ethical questions. Their use promises benefits for humanity and, specifically for infertile couples, the satisfaction of being parents. This article discusses the regulations and juridical implications of this activity, trying to take us into the actual international and national reality. lt is argued that human cloning promotes human life and dignity. In addition, it is proposed that this technique is best understood not in moralistic terms, but rather in terms of contexts that respond to real life situations, specifically an ethics of responsibility.

    Full Text Available Abstract Background To construct a recombinant adenovirus containing CDglyTK double suicide genes and evaluate the killing effect of the double suicide genes driven by kinase domain insert containing receptor (KDR promoter on human umbilical vein endothelial cells. Methods Human KDR promoter, Escherichia coli (E. coli cytosine deaminase (CD gene and the herpes simplex virus-thymidine kinase (TK gene were cloned using polymerase chain reaction (PCR. Plasmid pKDR-CDglyTK was constructed with the KDR promoter and CDglyTK genes. A recombinant adenoviral plasmid AdKDR-CDglyTK was then constructed and transfected into 293 packaging cells to grow and harvest adenoviruses. KDR-expressing human umbilical vein endothelial cells (ECV304 and KDR-negative liver cancer cell line (HepG2 were infected with the recombinant adenoviruses at different multiplicity of infection (MOI. The infection rate was measured by green fluorescent protein (GFP expression. The infected cells were cultured in culture media containing different concentrations of prodrugs ganciclovir (GCV and/or 5-fluorocytosine (5-FC. The killing effects were measured using two different methods, i.e. annexin V-FITC staining and terminal transferase-mediated dUTP nick end-labeling (TUNEL staining. Results Recombinant adenoviruses AdKDR-CDglyTK were successfully constructed and they infected ECV304 and HepG2 cells efficiently. The infection rate was dependent on MOI of recombinant adenoviruses. ECV304 cells infected with AdKDR-CDglyTK were highly sensitive to GCV and 5-FC. The cell survival rate was dependent on both the concentration of the prodrugs and the MOI of recombinant adenoviruses. In contrast, there were no killing effects in the HepG2 cells. The combination of two prodrugs was much more effective in killing ECV304 cells than GCV or 5-FC alone. The growth of transgenic ECV304 cells was suppressed in the presence of prodrugs. Conclusion AdKDR-CDglyTK/double prodrog system may be a useful

    Full Text Available En aquest article es presenta el mètode multisistèmic per a l’anàlisi de la comunicació humana. En primer lloc, es fa una revisió del concepte comunicació humana multisistèmica que s’entén com l’intercanvi de missatges complexos que es transmeten mitjançant una modalitat combinatòria de canals físics i somàtics. Aquests missatges són codificats i descodificats per sistemes semiòtics semblants, però alhora distints, que es coestructuren internament i s’interrelacionen els uns amb els altres amb l’únic objectiu de comunicar. Així doncs, la  comunicació humana multisistèmica no només és possible a través del sistema lingüístic que ens caracteritza y diferencia com a espècie, sinó que, a més a més, hi intervenen altres sistemes semiòtics que es coestructuren internament, s’interrelacionen els uns amb els altres i són coexpressius amb el llenguatge verbal. En segon lloc, es descriuen les investigacions més rellevants en aquest camp que examinen la correlació que es produeix entre els diferents sistemes semiòtics de la comunicació humana -principalment, llenguatge, parallenguatge i kinèsica-. Per tant, l’anàlisi de la comunicació humana multisistèmica estudia no només la diversitat de sistemes semiòtics que interactuen i s’interrelacionen, sinó també els mecanismes que regulen la relació que s’hi estableix. És per això que es considera el concepte de ‘sistema’ fonamentat en la Teoria General de Sistemes, i es justifica la selecció del mot ‘multisistèmic’ com l’alternativa més clara i inequívoca. Finalment, s’exposa el procés d’anàlisi multisistèmic, la descripció de les fases analítiques i els mètodes emprats, així com també la selecció dels instruments d’anàlisi que s’hi fan servir.

    The umbilical cord is tissue that is normally discarded after the delivery of the infant, but it has been shown to be a rich source of stem cells from the cord blood, Wharton's jelly, and umbilical endothelial cells. Patient-specific human induced pluripotent stem cells (hiPSCs) reprogrammed from patient specific human umbilical vein endothelial cells in the neonatal intensive care unit (NICU) population (specifically, premature neonates) have not been shown in the literature. This unit describes a protocol for the generation and expansion of hiPSCs originating from umbilical cords collected from patients in the NICU.

  13. Pregnancy hypertension and umbilical cord blood lead levels

    Rabinowitz, M.; Bellinger, D.; Leviton, A. (Children' s Hospital, Boston, MA (USA)); Needleman, H. (Children' s Hospital, Pittsburgh, PA (USA)); Schoenbaum, S. (Harvard Community Health Plan, Brookline Village, MA (USA))

    Pregnancy hypertension, blood pressure during labor, and the umbilical cord blood lead concentration were assessed in 3,851 women for whom additional demographic, medical, and personal information was available. Lead levels correlated with both systolic and diastolic blood pressure during labor. The incidence of clinically defined pregnancy hypertension, nearly 11% overall, increased with lead level. A series of multivariate models of pregnancy hypertension and of systolic blood pressure as a function of maternal age, parity, hematocrit, ponderal index, race, season, and diabetes were improved by including lead as a predictor variable. These other risk factors are not affected by the lead term. The relative risk for pregnancy hypertension doubles when lead increases from 2 to 15 {mu}g/dl. The effect is statistically strong, with a magnitude of about 3 mm for a 10 {mu}g/dl range, about the same magnitude associated with diabetes. At these observed levels (mean blood lead = 6.0 {mu}g/dl, SD = 3.3, range 0 > 35), not currently recognized as overtly toxic, lead has a small but demonstrable association with pregnancy hypertension and blood pressure at the time of delivery, but not with pre-eclampsia nor toxemia. Although this association is not likely to influence the clinical management of hypertension, it indicates that lead at typical contemporary urban levels, does effect multiple physiological functions.

    Full Text Available Dermatofibrosarcoma protuberans is a rare fibroblastic mesenchymal skin tumor with low - grade malignancy and occasional distant metastasis. The tumour accounts for less than 0.001% of all malignancies. Most cases involve the trunk, extremities, scalp, and neck. In rare cases, the genital urinary system may be affected. Diagnostic tools include computed tomography and magnetic resonance imaging. The standard treatment of wide - margin surgical excision with a clear margin of 3 - 4 cm may be problematic in large tumors or in some areas of the body, as a radical excision may produce unacceptable cosmetic, structural, or functional results. An un resected or positive margin should be treated with adjuvant radiotherapy to help prevent recurrence. Chemotherapy plays a limited role in treating this disease. This article describes a 55years male with mass in umbilical region who underwent wide local excision and rhombhoid flap transfer to cover the defect. Later patient sent for adjuvant radiotherapy, patient was tumour free at 6 months follow up.

    Initial Enterococcus faecalis-endothelial cell molecular interactions which lead to enterococci associating in the host endothelial tissue, colonizing it and proliferating there can be assessed using in vitro models. Cultured human umbilical vein endothelial cells (HUVEC) have been used to study other Gram-positive bacteria-cell interactions; however, few studies have been aimed at establishing the relationship of E. faecalis with endothelial cells. The aggregation substance (AS) family of adhesins represents an E. faecalis virulence factor which has been implicated in endocarditis severity and bacterial persistence. The Asc10 protein (a member of this family) promotes bacterium-bacterium aggregation and bacterium-host cell binding. Evaluating Asc10 role in bacterial internalization by cultured enterocytes has shown that this adhesin facilitates E. faecalis endocytosis by HT-29 cells. A few eukaryotic cell structural components, such as cytoskeletal proteins, have been involved in E. faecalis entry into cell-lines; it is thus relevant to determine whether Asc10, as well as microtubules and actin microfilaments, play a role in E. faecalis internalization by cultured endothelial cells. The role of Asc10 and cytoskeleton proteins in E. faecalis ability to enter HUVEC was assessed in the present study, as well as cell apoptosis induction by enterococcal internalization by HUVEC; the data indicated increased cell apoptosis and that cytoskeleton components were partially involved in E. faecalis entry to endothelial cells, thereby suggesting that E. faecalis Asc10 protein would not be a critical factor for bacterial entry to cultured HUVEC.

    To evaluate the hematopoietic potentiality and the migration and homing routine of separated as well as cryopreserved umbilical cord blood hematopoietic cells, the BALB/cnu(+) mice were used to establish a murine model. This can prepare for the clinical transplantation and the establishment of a large-scale cord blood bank. The result indicated that the hydroxyethyl starch (HES) sedimentation and DMSO step-by-step cryopreservation procedure resulted in only less losses of hematopoietic progenitor cells and also unharmful to the hematopietic potentiality. We can found evidence for successful transplantation in each mouse which received (1.0 - 2.0) x 10(7) separated or cryopresered hematopoietic cells from cord blood, which lasted for about fifty days. The results demonstrated that (1) HES sedimentation and DMSO cryopreservation procedure can keep the hematopoietic potentiality of cord blood, and so can be used to clinical transplantation or establishment of a cord blood bank; (2) Rich hematopoietic stem cells in human cord blood can cross the xenogenetic barriers and successfully engraft mice; (3) The hematopoietic cells migrated among bone marrow, liver, spleen, lung and kidney in the mice and homed to bone marrow by the end. Cryopreservation may influence the adhesion molecule on the hematopoietic cells and the homing behaviour, but not influence their hematopoietic potentiality.

  17. Improving engraftment and immune reconstitution in umbilical cord blood transplantation

    Full Text Available Umbilical cord blood (UCB is an important source of haematopoietic stem cells (HSC for allogeneic transplantation when HLA-matched sibling and unrelated donors (MUD are unavailable. Although the overall survival rates of UCB transplantation are comparable to the results with MUD, UCB transplants are associated with slow engraftment, delayed immune reconstitution, and increased opportunistic infections. While this may be a consequence of the lower cell dose in UCB grafts, it also reflects the relative immaturity of cellular immunity within cord blood. Furthermore, the limited number of cells and the non-availability of donor lymphocyte infusions (DLI currently prevent the use of post-transplant cellular immunotherapy to boost donor-derived immunity to treat infection, mixed chimerism and disease relapse. Therefore, to further develop UCB transplantation, many strategies to enhance engraftment and immune reconstitution are currently under investigation. This review summarises our current understanding of engraftment and immune recovery following UCB transplantation and why this differs from allogeneic transplants using other sources of HSC. It also provides an comprehensive overview of the promising techniques being used to improve myeloid and lymphoid recovery, including expansion, homing, and delivery of UCB HSC; combined use of UCB with third party donors; isolation and expansion of NK cells, pathogen specific T cells, and regulatory T cells; methods to protect and/or improve thymopoiesis. As many of these strategies are now in clinical trials, it is anticipated that UCB transplantation will continue to advance, further expanding our understanding of UCB biology and HSC transplantation.

    Full Text Available A case of a 30 year-old black, female patient, born in Angola, Africa with past history of multiple miscarriages is presented. She stated that the last pregnancy she had had abdominal pain, as well as some other less common discomfort. A great umbilical hernia defect was detected which affected the pregnant uterus and other abdominal viscera. It was necessary to admit the patient into the hospital during the last 10 weeks of pregnancy until the cesarean surgery and the hernia reparation was performed. The mother and infant developed satisfactorily and were discharged from the hospital. They were followed up in consultations to which they never assisted. The low frequency of occurrence of this association which was corroborated by means of national as well as international bibliographical revision. This led us to prepare this report.
    Se describe el caso de una paciente de raza negra, de 30 años de edad, natura de Angola, con antecedentes de múltiples abortos espontáneos, que durante su último embarazo había presentado dolores abdominales frecuentes, además de otras molestias poco comunes. Se detectó un gran defecto herniario umbilical, que afectaba el útero grávido y otras vísceras abdominales. Para llevar el embarazo a término fue necesario ingresar a la paciente durante las últimas 10 semanas de embarazo, hasta la realización de la cesárea y la cirugía de reparación de la hernia. Tanto la madre como el niño evolucionaron satisfactoriamente, siendo dados de alta con citación para consultas de seguimiento posterior a la cual no acudieron nunca. La escasa frecuencia con que se presenta esta asociación, lo cual fue corroborado mediante la revisión de la literatura nacional e internacional, es lo que condujo a la realización del presente informe.

    Pertussis is a vaccine-preventable disease that affects people of all ages. Young adults who have lost their immunity to pertussis are the major source of infection in infants. Given the steady increase of pertussis cases, new prevention strategies are required. Objective. To assess pertussis seroprevalence in adult blood donors, post-partum women, and umbilical cords. Metod. Measurement of total titers of anti-Bordetella spp. (Bordetella) antibodies using an enzyme-linked immunosorbent assay. Serum samples from 103 donors, 101 post-partum women and 100 umbilical cords were analyzed. Titers <80 were considered of low impact against the disease. The assessment included transplacental transfer of antibodies and the umbilical cord/maternal ratio of antibody titers. Results. Donors mean age was: 28 ± 6 years old. Mediananti-Bordetella titers: 320; interquartile range (IQR):160-320; 10% had titers <80. Post-partum women mean age was: 26 ± 6 years old. Median anti-Bordetella titers:160 (IQR:80-320), with titers significantly lower than in female donors (p= 0.00002). Titers <80 were found in 30% of post-partum women. Median anti-Bordetella titers in umbilical cords: 160 (IQR: 80-160). Titers <80 were more frequently found in umbilical cords than in mothers (44% versus 30%, p= 0.04). Transplacental transfer was 0.83. Umbilical cord titers were equal to maternal titers in 54% of cases, lower in 37%, and higher only in 8%. Conclusion. Titers of anti-Bordetella antibodies in post-partum women were significantly lower than in female blood donors. Titers <80 were found in 30% of post-partum women and 44% of umbilical cords. These data may account for the high rates of pertussis in young infants who have not yet completed their vaccination schedule.

    Full Text Available Background: Umbilical hernia repair, a common day-case surgery procedure in children, is associated with a significant postoperative pain. The most popular peripheral nerve blocks used in umbilical hernia repair are rectus sheath infiltration and caudal block. The rectus sheath block may offer improved pain relief following umbilical hernia repair with no undesired effects such as lower limb motor weakness or urinary retention seen with caudal block which might delay discharge from the hospital. Ultrasound guidance of peripheral nerve blocks has reduced the number of complications and improved the quality of blocks.The aim of this case series is to assess the post rectus sheath block pain relief in pediatric patients coming for umbilical surgery. Methods: Twenty two (22 children (age range: 1.5-8 years scheduled for umbilical hernia repair were included in the study. Following the induction of general anesthesia, the ultrasonographic anatomy of the umbilical region was studied with a 5-16 MHz 50 mm linear probe. An ultrasound-guided posterior rectus sheath block of both rectus abdominis muscles (RMs was performed (total of 44 punctures. An in-plain technique using Stimuplex A insulated facet tip needle 22G 50mm. Surgical conditions, intraoperative hemodynamic parameters, and postoperative analgesia by means of the modified CHEOPS scale were evaluated. Results: ultrasonograghic visualization of the posterior sheath was possible in all patients. The ultrasound guided rectus sheath blockade provided sufficient analgesia in all children with no need for additional analgesia except for one patient who postoperatively required morphine 0.1 mg/kg intravenously. There were no complications. Conclusions: Ultrasound guidance enables performances of an effective rectus sheath block for umbilical hernia.

    Objective: To study ultrasonic characteristics of umbilical cord blood flow in acute fetal distress and its correlation with umbilical artery blood gas parameters, oxidative stress parameters, neonatal brain injury and myocardial injury. Methods: The pregnant women delivered in Department of Obstetrics of our hospital were chosen during the period from May 2012 to August 2015. The pregnant women with acute fetal distress were included in the distress group, and the healthy pregnant women with no acute fetal distress were included in the control group. The resistance index (RI), pulsatility index (PI) and systolic/diastolic (S/D) ratio of umbilical artery were measured at 24–30 weeks, 31–36 weeks and 37–41 weeks of pregnancy. After delivery, umbilical artery blood was taken for analysis of blood gas and determination of oxidative stress parameters. The venous blood of newborns was taken to measure the myocardial injury and brain injury parameters. Results: At 24–30 weeks, 31–36 weeks and 37–41 weeks of pregnancy, RI, S/D and PI in pregnant women of distress group were significantly higher than those in control group. The pH, contents of arterial partial pressure of oxygen, vitamin C, vitamin E, superoxide dis-mutase and glutathione peroxidase in umbilical artery blood in pregnant women of distress group was significantly lower than those in control group and negatively correlated with the umbilical artery RI, PI and S/D. The contents of partial pressure of carbon dioxide in artery, lactic acid and malondialdehyde in pregnant women of distress group were significantly higher than those in control group and positively correlated with the umbilical artery RI, PI and S/D. The contents of lactate dehydrogenase, hydroxybutyrate dehydrogenase, creatine kinase, creatine kinase-MB, S100B, neuron-specific enolase, creatine kinase-BB and Tau in newborns' venous blood in distress group were significantly higher than those in control group and positively correlated

    Full Text Available Objective: In this in vitro study, we investigated the vasoactive effects of levobupivacaine and ropivacaine on vascular smooth muscle derived from human umbilical arteries and veins.Material and Methods: The strips were mounted in tissue baths at 37°C continuously gassed with 5% CO2 in oxygen for isometric recording of contractile activity on a polygraph. The endothelium of some tissues was mechanically removed to assess the influence of the endothelium on contractility. The strips were precontracted with serotonin (10-6 M 5-HT; n=7. After obtaining the maximal contraction, responses obtained by adding levobupivacaine and ropivacaine (10-9-10-4 M; n=7 cumulatively were recorded. Contractions were expressed as the (% of 5HT maximal response percentage of 5 HT’s maximal response.Results: Both levobupivacaine and ropivacaine induce a concentration-dependent contraction in the smooth muscle cells of umbilical arteries and veins. Maximum contractile response (Emax of levobupivacaine (79.2±2.5, 71.1±2.6 was higher than ropivacaine (68.4±2, 36.2±2.8 on both umbilical arteries and veins. There were no statistically significant differences between contraction responses of endothelium-intact and endothelium-denuded tissues. Conclusion: The results suggest that, in high concentrations, levobupivacaine and ropivacaine may affect umbilical blood flow by contracting the umbilical artery and vein, thus reducing fetal blood flow.

    Project Goals: a) Design the compliance mechanism for the CSITU system to a 30% level -3D models completed in Pro/Engineer -Relevant design analysis b) Must meet all system requirements and establish basis for proceeding with detailed design. Tasks to be completed: A design that meets requirements for the 30% design review, 01/16/2013. Umbilical arms provide commodities to the launch vehicle prior to T-0. Commodities can range anywhere from hydraulics, pneumatics, cryogenic, electrical, ECS, etc ... Umbilicals commonly employ truss structures to deliver commodities to vehicle. Common configurations include: -Tilt-up -Swing Arm -Hose Drape -Drop Arm Umbilical arms will be mounted to Mobile Launch Platform. SLS currently has 9 T-0 umbilical arms. The compliance refers to the ability of the umbilical to adjust to minor changes in vehicle location. The compliance mechanism refers to the mechanism on the ground support equipment {GSE) that compensates for these changes. For the CSITU, these minor changes, or vehicle excursions, can be up to +4 in. Excursions refer to movements of the vehicle caused by wind loads and thermal expansion. It is ideal to have significant vertical compliance so a passive secondary release mechanism may be implemented.

    Full Text Available Abstract Introduction The incidence of hernias is increased in patients with alcoholic liver disease with ascites. To the best of our knowledge, this is the first report of an acute rise in intra-abdominal pressure from straining for stool as the cause of a ruptured umbilical hernia. Case presentation An 81-year-old Caucasian man with a history of alcoholic liver disease presented to our emergency department with an erythematous umbilical hernia and clear, yellow discharge from the umbilicus. On straining for stool, after initial clinical assessment, our patient noted a gush of fluid and evisceration of omentum from the umbilical hernia. An urgent laparotomy was performed with excision of the umbilicus and devitalized omentum. Conclusion We report the case of a patient with a history of alcoholic liver disease with ascites. Ascites causes a chronic increase in intra-abdominal pressure. A sudden increase in intra-abdominal pressure, such as coughing, vomiting, gastroscopy or, as in this case, straining for stool can cause rupture of an umbilical hernia. The presence of discoloration, ulceration or a rapid increase in size of the umbilical hernia signals impending rupture and should prompt the physician to reduce the intra-abdominal pressure.

    No previous reports have focused on surgical treatments and risk factors of umbilical hernia alone in peritoneal dialysis (PD) patients. Herein, we evaluated the treatments and risk factors. A total of 411 PD patients were enrolled. Of the 15 patients with umbilical hernia (3.6%), six underwent hernioplasty. There was no recurrence in five patients treated with tension-free hernioplasty. The mean PD vintage after onset of hernia in the hernioplasty group tended to be longer than that in the non-hernioplasty group. An incarcerated hernia occurred in one non-hernioplasty patient. Although the incidence was significantly higher among women (P = 0.02), female sex was not a risk factor for umbilical hernia (P = 0.08). Our findings suggest that umbilical hernias should be repaired for continuing PD. Furthermore, there were no significant risk factors for umbilical hernia in PD patients. Future studies with larger sample groups are required to elucidate these risk factors.

    Mesh repair has evolved as the gold standard for umbilical hernias. Surgical reconstruction of umbilical hernias in association with diastasis recti has not been discussed in the recent literature. We describe a novel surgical technique of midline mesh repair for this combined lesion. This is a retrospective review of 44 consecutive patients. Forty-four patients underwent surgery for umbilical hernia with diastasis recti between January 2010 and August 2012. All excess skin, subcutaneous tissue, and distracted midline (linea alba) were excised supraumbilically and paraumbilically according to preoperative marking. Surgical repair began with a midline running suture of the posterior rectal sheath. A light prolene mesh was placed retromuscularly into this sheath and anchored in all directions with a distance of about 5 cm from the midline using U-shaped stitches. The anterior rectal fascia was closed with a continuous suture. All information was obtained from the hospital records. The median operative time was 93.3 minutes (28 to 219 minutes). The median length of postoperative hospital stay was 5.9 days (3 to 12 days). There was no major complication. One minimal umbilical skin necrosis was observed. Analgesic medication was required in all patients. Opiods were added in 84.0% of patients on day 1, in 75.0% on day 3, and in 2.3% on day 7. Our novel technique of sublay mesh repair for combined umbilical hernia and diastasis recti is safe and effectively restores the abdominal midline.

    Full Text Available INTRODUCTION: The waiting times for elective surgery of Umbilical hernia (UH in adults are unacceptably long in some cases. During this period, irreducibility and strangulation are possible. We operate on adult patients under local anaesthesia (LA as day cases to avoid this delay and describe our experience in this paper. AIMS: The aims of our study were to look at the age and sex distribution, body weight, type and amount of local anaesthetic used, morbidity, admission and readmission rates, and waiting times of adult patients operated on for UH under LA. MATERIALS AND METHODS: It was a retrospective study covering a 4 year period from July 1996 to June 2000 including all adult patients undergoing the above procedure under the care of a single consultant general surgeon. A standard Mayo repair using non absorbable material was used without a mesh or a drain. RESULTS: 32 patients with UH were operated on under LA, 23 males and 9 females with a median age of 51 years (range 20 to 86 years. The body weight ranged from 63 to 120 (median 87 kg. The average duration of the procedure was 30 (range 22-40 minutes. Sedation was needed in 4 patients. Two patients developed wound infections, one superficial and one deep. There was no mortality. The median period of follow-up was 24 (range 4-48 months and there was no recurrence. The median waiting time for the operation was 6 weeks. CONCLUSIONS: Day case local anaesthetic repair of UH in adults seems to be safe and feasible with an acceptable morbidity. Suture repair in the right patient has excellent results and the waiting times are acceptable.

  10. Umbilical cord blood banks. Ethical aspects. Public versus private banks.

    2012-01-01

    The creation of umbilical cord blood (UCB) banks raises interesting medical, social, economic and ethical issues. This paper reviews the ethical problems specifically. In this respect, it evaluates: a) whether there are advantages to the use of UCB compared to bone marrow, b) whether or not it is ethical to create UCB banks, c) whether their creation is ethically acceptable in terms of their clinical usefulness or d) the use made of them for therapeutic purposes, and finally e) whether their creation is ethically justified from a cost/profitability point of view. We focus primarily on evaluating the ethical controversy between public and private banks, particularly on whether it is ethical to bank autologous blood in private UCB banks, on the basis of its limited possibilities for use by the cord blood donor. We can conclude that, from an ethical point of view, autologous blood banks have limited acceptance among specialised researchers, scientific societies and other public institutions. Therefore, we believe that it is ethically more acceptable to support the creation of public UCB banks for medical and social reasons and, above all, based on the principle of justice and human solidarity. Nevertheless, there is no definitive ethical argument why a couple, according to their autonomy and freedom, cannot bank their child's UCB in a private bank. An equally acceptable solution could be the creation of mixed banks, such as that proposed by the Virgin Health Bank or like the Spanish system where autologous samples can be stored in public banks but with the proviso that if at any time the stored sample is required by any person other than the donor, it would have to be given to them.

    Full Text Available Abstract Background There are no published studies on stem cells from equine cord blood although commercial storage of equine cord blood for future autologous stem cell transplantations is available. Mesenchymal stem cells (MSC have been isolated from fresh umbilical cord blood of humans collected non-invasively at the time of birth and from sheep cord blood collected invasively by a surgical intrauterine approach. Mesenchymal stem cells isolation percentage from frozen-thawed human cord blood is low and the future isolation percentage of MSCs from cryopreserved equine cord blood is therefore expectedly low. The hypothesis of this study was that equine MSCs could be isolated from fresh whole equine cord blood. Results Cord blood was collected from 7 foals immediately after foaling. The mononuclear cell fraction was isolated by Ficoll density centrifugation and cultured in a DMEM low glucose based media at 38.5°C in humidified atmosphere containing 5% CO2. In 4 out of 7 samples colonies with MSC morphology were observed. Cellular morphology varied between monolayers of elongated spindle-shaped cells to layered cell clusters of cuboidal cells with shorter cytoplasmic extensions. Positive Alizarin Red and von Kossa staining as well as significant calcium deposition and alkaline phosphatase activity confirmed osteogenesis. Histology and positive Safranin O staining of matrix glycosaminoglycans illustrated chondrogenesis. Oil Red O staining of lipid droplets confirmed adipogenesis. Conclusion We here report, for the first time, the isolation of mesenchymal-like stem cells from fresh equine cord blood and their differentiation into osteocytes, chondrocytes and adipocytes. This novel isolation of equine cord blood MSCs and their preliminary in vitro differentiation positions the horse as the ideal pre-clinical animal model for proof-of-principle studies of cord blood derived MSCs.

    Full Text Available Bovinos jovens são frequentemente acometidos por hérnias umbilicais. Neste trabalho, avaliou-se a ocorrência e estabeleceu-se o tratamento cirúrgico para hérnias umbilicais em bovinos jovens, empregando 78 bezerros distribuídos em seis grupos. Em GI e GIV, na laparorrafia, utilizou-se sutura jaquetão; em GII e GV, jaquetão modificado e, em GIII e GVI, sutura separada simples com pontos de relaxamento. Em GI, GII e GIII utilizou-se fio de algodão e, em GIV, GV e GVI, de náilon. Dados não paramétricos, envolvendo a recuperação dos animais e sua independência ou associações com o padrão de sutura foram analisados pelo teste do Qui-quadrado e Exato de Fisher, fazendo-se uso do programa computacional Statistical Analysis System, a 5% (p < 0,05. Os demais resultados foram analisados descritivamente. A ocorrência de hérnia umbilical em bovinos foi expressiva e a herniorrafia, empregando-se fio de algodão, apresentou maiores complicações pós-operatórias; porém a maioria dos animais recuperou-se. O fio e o padrão de sutura, manejo pós-operatório, resposta individual e o tamanho do anel herniário influenciam na reabilitação dos animais e na redução das complicações pós-operatórias.

    Due to their relative abundance, stable biological properties and excellent reproductive activity,umbilical cord mesenchymal stem cells have previously been utilized for the treatment of Duchenne muscular dystrophy, which is a muscular atrophy disease. Three patients who were clinically and pathologically diagnosed with Duchenne muscular dystrophy were transplanted with umbilical cord mesenchymal stem cells by intravenous infusion, in combination with multi-point intramuscular injection. They were followed up for 12 months after cell transplantation. Results showed that clinical symptoms significantly improved, daily living activity and muscle strength were enhanced,the sero-enzyme, electromyogram, and MRI scans showed improvement, and dystrophin was expressed in the muscle cell membrane. Hematoxylin-eosin staining of a muscle biopsy revealed that muscle fibers were well arranged, fibrous degeneration was alleviated, and fat infiltration was improved. These pieces of evidence suggest that umbilical cord mesenchymal stem cell transplantation can be considered as a new regimen for Duchenne muscular dystrophy.

    2009-06-01

    On rare occasions, uterine fibroids complicate pregnancy. More commonly, fibroids exert a mass effect that either prevents implantation of an egg or becomes problematic as a fetus grows. Less frequently, pregnancies are affected by fibroid herniation through a fascial defect. Several publications describing herniation of pedunculated fibroids exist, two of which were in umbilical hernia sacs. There is, to our knowledge, only one publication describing the presence of a sessile uterine fibroid in an umbilical hernia. This case report adds to the literature by describing a 34-year-old primigravid woman with an umbilical hernia that contained a sessile uterine fibroid and provides parameters that can be used in the initial evaluation of a pregnant woman with an abdominal wall hernia.

    A 62-year-old Japanese woman who had developed massive cirrhotic ascites was referred to our hospital for a peritoneovenous shunt implant. However, CT examination revealed an umbilical hernia that had not been observed before the peritoneovenous shunt was implanted. We decided to perform laparoscopic umbilical hernia repair to keep carbon dioxide from flowing backward into the central circulatory system. We first clamped the catheter and set the upper limit of the pneumoperitoneum pressure to 6 mmHg. The central venous pressure was also measured simultaneously. Mesh was then applied over the hernia and fixed by the double-crown technique. Finally, 1000-mL physiological saline was infused into the abdominal cavity while the pneumoperitoneum was slowly released. In this case, we safely performed laparoscopic umbilical hernia repair while making some alterations, specifically catheter clamping, reducing pneumoperitoneum pressure, monitoring central venous pressure, and infusing physiological saline.

    Full Text Available Abstract Background Abnormal venous connections involving a persistent right umbilical vein are rare. In a minority of cases the liver is entirely bypassed and the condition is associated with multiple congenital malformations. Case presentation The described case illustrates a systemic venous drainage that was severely abnormal in a newborn girl with a truncus arteriosus type II congenital heart defect. Injection of contrast medium through the umbilical vein catheter revealed a very peculiar venous connection that passed anterio-laterally through the right hemithorax before crossing in an oblique fashion towards the superior vena cava. Conclusions This venous drainage may be the result of a persistent right umbilical vein connecting with the superior vena cava.

  10. Ex Vivo Expansion or Manipulation of Stem Cells to Improve Outcome of Umbilical Cord Blood Transplantation.

    Science.gov (United States)

    Horwitz, Mitchell E

    2016-02-01

    The outcome of umbilical cord blood transplantation for adult patients with hematologic malignancies now rivals that of matched unrelated donor transplantation. However, delayed hematopoietic and immunologic recovery remains a source of significant morbidity and mortality. Multiple strategies are now being studied to overcome these limitations. One strategy involves ex vivo expansion of the umbilical cord blood unit prior to transplantation. A second strategy involves exposure of the umbilical cord blood graft to compounds aimed at improving homing and engraftment following transplantation. Such a strategy may also address the problem of slow hematopoietic recovery as well as the increased risk of graft failure. Many of these strategies are now being tested in late phase multi-center clinical trials. If proven cost-effective and efficacious, they may alter the landscape of donor options for allogeneic stem cell transplantation.

    2011-05-01

    Full Text Available Abstract Background High abundance protein depletion is a major challenge in the study of serum/plasma proteomics. Prior to this study, most commercially available kits for depletion of highly abundant proteins had only been tested and evaluated in adult serum/plasma, while the depletion efficiency on umbilical cord serum/plasma had not been clarified. Structural differences between some adult and fetal proteins (such as albumin make it likely that depletion approaches for adult and umbilical cord serum/plasma will be variable. Therefore, the primary purposes of the present study are to investigate the efficiencies of several commonly-used commercial kits during high abundance protein depletion from umbilical cord serum and to determine which kit yields the most effective and reproducible results for further proteomics research on umbilical cord serum. Results The immunoaffinity based kits (PROTIA-Sigma and 5185-Agilent displayed higher depletion efficiency than the immobilized dye based kit (PROTBA-Sigma in umbilical cord serum samples. Both the PROTIA-Sigma and 5185-Agilent kit maintained high depletion efficiency when used three consecutive times. Depletion by the PROTIA-Sigma Kit improved 2DE gel quality by reducing smeared bands produced by the presence of high abundance proteins and increasing the intensity of other protein spots. During image analysis using the identical detection parameters, 411 ± 18 spots were detected in crude serum gels, while 757 ± 43 spots were detected in depleted serum gels. Eight spots unique to depleted serum gels were identified by MALDI- TOF/TOF MS, seven of which were low abundance proteins. Conclusions The immunoaffinity based kits exceeded the immobilized dye based kit in high abundance protein depletion of umbilical cord serum samples and dramatically improved 2DE gel quality for detection of trace biomarkers.

In several reports,reliablity of blood cultures were done from umbi lical catheters,have been demonstrated. The objective of the present study was to determine,wether an inde welling umbilical catheter, could be an alternative site for blood culture. In a prospective study over 6 months during 2006,141 paired blood cultures from 134 infant,were done simultaneously from peripheral site and umbilical catheter (mostly U. V. C,during the first four days of life. Majority of these infants were preterm and admitted to NICU for special care. these infants had indwelling umbilical line and had indication of sepsis workup. A total of 141 pairs of blood cultures were obtained from 134 infants. In 16 infants blood culture pairs were positive for one organism in both peripheral vein and umbilical site. 71. 6% of total cultures (n=11pairs were negative in boths site. A total of 22 pairs were positive in one site only,with 5 positive from peripheral vein only and the other 17 from umblical site. Two pairs were positve in boths site with two different organism. In over all 16 infant (11%of blood were considered to be contaminated. Contamination rate were 2. 4% and 9. 2% for peripheral and umbilical catheter site. Contamination rate increased after 48 hours of age in umbilical catheter. The result showed that after 2 days contamination rate for blood culture taken from catheter line increased and specifity decreased. We recommended that blood culture via umblical catheter in first 2 days in sick neonates with indwelling catheter can be a alternate site of blood culture sampelling.

    We present two cases of umbilical hernia incarceration following large volume paracentesis (LVP) in patients with cirrhotic ascites. Both patients became symptomatic within 48 hours after the LVP. Although being rare, given the significantly higher mortality rate of cirrhotic patients undergoing emergent herniorrhaphy, this complication of LVP is potentially serious. Therefore, it is recommended that patients be examined closely for the presence of umbilical hernias before removal of ascitic fluid and an attempt should be made for external reduction of easily reducible hernias, if a hernia is present.

    Full Text Available A abordagem de Tomasello da evolução da cognição humana busca integrar processos biológicos, comportamentais e culturais em um mesmo sistema explicativo. No entanto, uma das principais críticas a essa abordagem é a necessidade de uma melhor elaboração do conceito de intencionalidade. O objetivo do presente trabalho foi: (1 analisar o tratamento de Tomasello do conceito de intencionalidade; e (2 estabelecer interlocuções desse tratamento com teorias da intencionalidade na filosofia da mente e com abordagens funcionalistas da cognição humana na psicologia comportamental. Sugerimos que o tratamento do conceito de intencionalidade na abordagem de Tomasello é compatível com essas teorias e abordagens. Além disso, a abordagem de Tomasello pode ampliar a investigação de processos simbólicos mais complexos do que aqueles tradicionalmente investigados pela psicologia comportamental.

    Background: Fetal bovine serum (FBS) is widely used in cell culture laboratories, risk of zoonotic infections and allergic side effects create obstacles for its use in clinical trials. Therefore, an alternative supplement with proper inherent growth-promoting activities is demanded. Objective: To find FBS substitute, we tested human umbilical cord blood serum (hUCS) for proliferation of human umbilical cord matrix derived mesenchymal stem cells (hUC-MSCs) and human bone marrow-derived mesenchymal cells (hBM-MSCs). Materials and Methods: Umbilical cord blood of healthy neonates, delivered by Caesarian section, was collected and the serum was separated. hUC-MSCs and hBM-MSCs were isolated and characterized by assessment of cell surface antigens by flow cytometry, alkaline phosphatase activity and osteogenic/adipogenic differentiation potential. The cells were then cultured in Iscove's Modified Dulbecco's Medium (IMDM) by conventional methods in three preparations: 1- with hUCS, 2- with FBS, and 3- without serum supplements. Cell proliferation was measured using WST-1 assay, and cell viability was assessed by trypan blue staining. Results: The cells cultured in hUCS and FBS exhibited similar morphology and mesenchymal stem cells properties. WST-1 proliferation assay data showed no significant difference between the proliferation rate of either cells following hUCS and FBS supplementation. Trypan blue exclusion dye test also revealed no significant difference for viability between hUCS and FBS groups. A significant difference was detected between the proliferation rate of stem cells cultured in serum-supplemented medium compared with serum-free medium. Conclusion: Our results indicate that human umbilical cord serum can effectively support proliferation of hBM-MSCS and hUC-MSCs in vitro and can be used as an appropriate substitute for FBS, especially in clinical studies.

    High-grade glioma is the most common malignant primary brain tumor in adults. The poor prognosis of glioma, combined with a resistance to currently available treatments, necessitates the ment of more effective tumor-selective therapies. Stem cel-based therapies are emerging as novel cel-based delivery vehicle for therapeutic agents. In the present study, we successful y isolated human umbilical cord mesenchymal stem cel s by explant culture. The human umbilical cord senchymal stem cel s were adherent to plastic surfaces, expressed specific surface phenotypes of mesenchymal stem cel s as demonstrated by flow cytometry, and possessed multi-differentiation potentials in permissive induction media in vitro. Furthermore, human umbilical cord mesenchymal stem cel s demonstrated excel ent glioma-specific targeting capacity in established rat glioma models after intratumoral injection or contralateral ventricular administration in vivo. The excellent glioma-specific targeting ability and extensive intratumoral distribution of human umbilical cord mesenchymal stem cel s indicate that they may serve as a novel cel ular vehicle for delivering the-rapeutic molecules in glioma therapy.

    Abstract Rationale: Few case reports of umbilical arteriovenous malformation (AVM) have been reported. Herein, we report a neonatal case of umbilical AVM who underwent liver failure after surgical excision. Patient concerns: The patient was a girl delivered at a gestational age of 39+5 weeks showing cyanosis and heart murmur. Diagnoses: Cardiac echography, abdominal ultrasonography (USG), and computed tomography revealed suspecting the umbilical AVM. Interventions: On the eighth day after birth, because of the aggravation of heart failure, emergency surgery for excision of umbilical AVM was performed. Outcomes: In postoperative state, worsened laboratory test of liver function and coagulopathy indicated the liver failure. Abdominal USG revealed that the portal vein (PV) flow primarily occurred from the left PV to the inferior vena cava via ductus venosus and coarse hepatic echogenicity. After conservative management, laboratory findings of liver function and the flow direction of the left PV were normal, as demonstrated by abdominal USG within 50th postoperative day. Lessons: Careful preoperative evaluation of an AVM of a large size with significant blood flow should be performed, and the possibility of liver failure after surgery should always be considered.

    Full Text Available OBJETIVOS: A presença de micotoxinas em alimentos tem sido correlacionada a várias patologias humanas, e as autoridades de saúde no mundo todo têm implementado ações para diminuir a ingestão desses compostos pela dieta. Realizou-se pesquisa para analisar os níveis de aflatoxinas e ocratoxina A de alimentos para consumo e avaliar o potencial de risco da exposição humana a essas micotoxinas. MÉTODOS: Foram analisadas 366 amostras de alimentos consumidos no Distrito Federal, no período de julho de 1998 a dezembro de 2001, como amendoim e derivados, castanhas, milho, produtos de trigo e/ou aveia, arroz e feijão. As amostras foram processadas, e as micotoxinas extraídas, detectadas e quantificadas por fluorescência após separação em cromatografia camada delgada. RESULTADOS: Foram detectadas aflatoxinas em 19,6% das amostras, em amendoim cru e derivados, milho de pipoca, milho em grão e castanha-do-pará (>2 mig/kg. Amendoim e derivados apresentaram maior incidência de contaminação por aflatoxinas (34,7% com amostras contendo até 1.280 mig/kg de AFB1+AFG1 e 1.706 mig/kg de aflatoxinas totais. Das amostras positivas, AFB1 estava presente em 98,5%, AFB2 em 93%, AFG1 em 66,7% e AFG2 em 65,4%. A ocratoxina A não foi detectada (<25 mig/kg em nenhuma amostra analisada. CONCLUSÃO: Os níveis de contaminação encontrados em amendoim e derivados ultrapassaram os níveis máximos permitidos pela legislação brasileira, podendo significar fator de risco para a população que os consome regularmente. A conscientização dos produtores de alimentos e as ações de vigilância sanitária permanentes são essenciais para diminuir a exposição humana a esses compostos e prevenir doenças crônicas advindas dessa exposição.

    In accordance with the tension-free principles for other hernias, umbilical and epigastric hernia repair should probably be mesh-based. The number of randomized studies is increasing, most of them showing significantly less recurrences with the use of a mesh. Different devices are available and are applicable by several approaches. The objective of this review was to evaluate recent literature for the different types of mesh for umbilical and epigastric hernia repair and recurrences after mesh repair. A multi-database search was conducted to reveal relevant studies since 2001 reporting mesh-based repair of primary umbilical/epigastric hernia and their outcomes in adult patients. A total of 20 studies were included, 15 of them solely involved umbilical hernias, whereas the remaining studies included epigastric hernias as well. A median of 124 patients (range, 17-384) was investigated per study. Three quarters of the included studies had a follow-up of at least 2 years. Six studies described the results of laparoscopic approach, of which one reported a recurrence rate of 2.7 %; in the remaining studies, no recurrences occurred. Two comparative studies reported a lower incidence of complications and postoperative pain after laparoscopic repair compared to open repair. Seventeen studies reported results of open techniques, of which seven studies showed no recurrence. Other studies reported recurrence rates up to 3.1 %. A wide range of complication rates were reported (0-33 %). This collective review showed acceptable recurrence rates for mesh-based umbilical and epigastric hernia repair. A wide range of devices was investigated. A tendency toward more complications after laparoscopic repair was found compared to open repair.

    Full Text Available Background : Umbilical defects may cause technical problems for general surgeons in patients during laparoscopic cholecystectomy (LC operations and may increase the incidence of incisional hernia. Aim : The objectives of this study were to determine the optimal repair method for umbilical hernias that already exist or are encountered incidentally and to present data regarding potential problems that may occur during LC. Settings and Design : Medical records of patients who had received simultaneous umbilical hernia repair (UHR with LC were investigated retrospectively. Materials and Methods : Cholelithiasis was accompanied by umbilical hernia in 64 (8.6% out of 745 patients who underwent LC and UHR simultaneously in our hospital between 2000 and 2004. Statistical Analysis Used : The Mann-Whitney U, Chi-square, One-Way Anova, Kaplan-Meier survival analysis, the log-rank test and t test were used for statistical analyses. Results : LC was followed by UHR using primary suture (Group 1, Mayo repair (Group 2 and flat mesh-based repair (Group 3 in 32 (50%, 18 (28.1% and 14 (21.9% patients, respectively. Mean body mass indexes (BMI of patients were 26.6 kg/m 2 , 29.2 kg/m 2 and 39.9 kg/m 2 in Groups 1, 2 and 3, respectively. Recurrence rates were 9.4%, 5.6% and none (0% in Groups 1, 2 and 3, respectively. Recurrence was observed in three (7.0% out of 43(67.2% patients with BMI≥30 kg/m 2 while umbilical hernia recurred in one (4.8% out of 21 (32.8% patients with BMI< 30 kg/m 2 . Overall morbidity and mortality rates were 14.1% and 0%, respectively. Conclusions : The outcomes of the UHR with mesh after laparoscopic surgeries appear to be better for either obese or non-obese patients than primary suture techniques in recurrence rates.

  4. Simultaneous measurements of umbilical uptake, fetal utilization rate, and fetal turnover rate of glucose.

    Fetal umbilical glucose uptake was compared with simultaneous measurements of glucose turnover and utilization rates in 12 pregnant sheep, at a mean of 137 days gestational age (range, 118-146 days). Umbilical glucose uptake was calculated by application of the Fick principle. Fetal glucose turnover rate was measured by a primed-constant infusion of [14C]- and [3H]glucose (glucose turnover rate = tracer infusion rate divided by fetal glucose sp act). The calculation of fetal glucose utilization rate required substraction of the loss of tracer to the placenta from the tracer infusion rate, thus defining the net tracer entry into the fetus for direct comparison with the net umbilical glucose uptake. In fed, normoglycemic sheep, these measurements demonstrated statistical equivalence of umbilical glucose uptake rate (4.77 mg.min-1.kg-1 +/- 0.34 SE) and glucose utilization rate ([14C]glucose, 5.58 mg.min-1.kg-1 +/- 0.54 SE; and [3H]glucose, 7.19 mg.min-1.kg-1 +/- 1.24 SE) when tested by two-way analysis of variance (P greater than 0.1). In three fasted, hypoglycemic sheep, the umbilical glucose uptake rate fell to 1.43 mg.min-1.kg-1 +/- 0.56 SE, which was considerably lower than the simultaneous glucose utilization rate ([14C]glucose, 4.78 mg.min-1.kg-1 +/- 0.48 SE; and [3H]glucose, 6.81 mg.min-1.kg-1 +/- 2.19 SE). Thus, in the normoglycemic, late-gestation fetal lamb, there appears to be little glucogenesis, whereas glucogenesis may become significant during fasting-induced fetal hypoglycemia.

    Hernias are a common occurrence with correspondingly huge clinical and economic impacts on the healthcare system. The most common forms of hernia which need to be diagnosed and treated in routine urological work are inguinal and umbilical hernias. With the objective of reconstructing and stabilizing the inguinal canal there are the possibilities of open and minimally invasive surgery and both methods can be performed with suture or mesh repair. Indications for surgery of umbilical hernias are infrequent although this is possible with little effort under local anesthesia. This article presents an overview of the epidemiology, pathogenesis, clinical symptoms, diagnostics and therapy of inguinal, femoral and umbilical hernias.

    Full Text Available The promotion of human health must be embedded in the wider pursuit of ecosystem health. Interventions will be impaired if ecosystem-linked determinants of health are not taken into account. In the extreme case, if ecosystems lose their capacity for renewal, society will lose life support services. Essential features of ecosystem health are the capacity to maintain integrity and to achieve reasonable and sustainable human goals. An ecosystem approach to research and management must be transdisciplinary and assure participation of stakeholders. These requisites provide a means for science to better deal with the complexity of ecosystems, and for policy-makers and managers to establish and achieve reasonable societal goals. The ecosystem approach can determine links between human health and activities or events which disturb ecosystem state and function. Examples are: landscape disturbance in agriculture, mining, forestry, urbanization, and natural disasters. An understanding of these links can provide guidance for management interventions and policy options that promote human health. An ecosystem approach to management must be adaptive because of irreducible uncertainty in ecosystem function.A promoção da saúde humana deve estar embutida na busca maior pela saúde do ecossistema. As intervenções estarão prejudicadas se os determinantes ecossistêmicos da saúde não forem levados em conta. Em caso extremo, se os ecossistemas perderem a capacidade de se renovarem, a sociedade ficará privada de serviços essenciais à sustentação da vida. As características essenciais da saúde ecossistêmica são a capacidade de manter a integridade e a de atingir metas humanas razoáveis e sustentáveis. Uma abordagem ecossistêmica para a pesquisa e gestão deve ser transdisciplinar e assegurar a participação dos diferentes atores. Tais características fornecem um meio à ciência para lidar melhor com a complexidade dos ecossistemas, bem como aos

A contrapelo desta tendência, lembra-se aqui o vínculo da ação complexa com sentidos para sempre locais e a necessidade, em se observando tal ponto, de se imaginarem “descrições densas” que procurem reconstruir a riqueza e as particularidades desses mesmos sentidos, como se pertencessem a um texto literário.

El texto formula también una crítica a todo intento de sustitución de la ética filosófica por las neurociencias (neuroética en modo-su. En consecuencia, se exploran los fundamentos ontológicos y antropológicos más apropiados para desarrollar la neuroética, entendida esta como territorio de colaboración entre ética y neurociencias. Dichos fundamentos remiten a la idea aristotélica de sustancia hilemórfica. Sobre tales fundamentos se puede desarrollar una neuroética colaborativa que incluye dos vertientes: por un lado tenemos una ética de la neurociencia y, por otro, una neurociencia de la ética. La primera muestra cómo investigar y aplicar la neurociencia preservando siempre la dignidad humana. La segunda nos enseña cuáles son las bases neurobiológicas posibilitadoras –pero no determinantes– de la agencia moral. Al estudiar las mismas se hace evidente nuestra vulnerabilidad como agentes morales. Esta vulnerabilidad, que arraiga en la propia naturaleza humana, ha de ser, como se argumenta en el último tramo del texto, reconocida y a la vez mitigada.

    Full Text Available En este artículo se analizan dos facetas importantes de las enfermedades infecciosas emergentes. Por un lado, las características de los microorganismos que las causan, por otro, las características del ser humano que promueven o contribuyen al surgimiento de las enfermedades infecciosas. Desde el punto de vista microbiano, se pueden identificar tres aspectos fundamentales. Primero, los patógenos emergentes son predominantemente virales, seguidos por los bacterianos. Numéricamente los virus ARN dominan, constituyendo el 37% de todos los patógenos emergentes. Los virus ARN predominan entre los virus patógenos emergentes que aparentemente entraron en las poblaciones humanas en las últimas décadas, como VIH y el coronavirus asociado al SARS. Segundo, los patógenos emergentes no se asocian a un único tipo de hospedero, sino que usualmente tienen amplio rango de hospederos que incluye varios órdenes de especies de mamíferos y no mamíferos. En efecto, la mayoría de las infecciones emergentes son de origen zoonótico. Tercero, los patógenos emergentes tienen un cierto grado de flexibilidad biológica que les permite aprovecharse de nuevas oportunidades epidemiológicas para ingresar a las poblaciones humanas. Las enfermedades infecciosas no son un problema reciente sino que han estado "emergiendo" a lo largo de la historia de la humanidad y es posible identificar, al menos, cuatro transiciones históricas. La última de esas transiciones es la globalización actual. Muchos factores antropogénicos inciden en el surgimiento de las enfermedades infecciosas emergentes, incluyendo eventos sociales, comportamiento humano, cambios ambientales, políticas en salud pública, procedimientos médicos y otros.

Para ello, éste será descompuesto en tres partes, que son sus pilares básicos: a los sujetos diseñados no pueden auto-concebirse a sí mismos como autores únicos de sus vidas; b la distinción kantiana entre objetos y personas se desvanece como consecuencia del modo en que los sujetos modificados experiencian su cuerpo; c la relación entre los padres y su descendencia se vuelve asimétrica, de modo que es contraria a las normas de la acción comunicativa. Segundo, en la sección 3, que es concebida como un diálogo entre Habermas y sus críticos, se presentarán algunas objeciones teóricas a su argumento. Tercero, la sección 4 analizará la validez de los argumentos habermasianos y afirmará firmemente que la posición de Habermas arroja luz sobre el modo correcto de analizar las tecnologías de mejora humana desde un punto de vista moral. A saber, en función de la influencia que tienen sobre el modo en que los sujetos se auto-conciben como seres autónomos y responsables.

    2014-10-01

    Full Text Available A reprodução humana assistida em uniões homoafetivas é uma temática envolta em controvérsias na sociedade contemporânea, motico pelo qual o Poder Judiciário frequentemente é acionado no intuito de dirimir os conflitos existentes. Apesar da união de pessoas do mesmo sexo ser uma configuração familiar cada vez mais frequente no Brasil, o ordenamento brasileiro ainda é frágil em relação ao deslinde da questão. A inexistência de mecanismos legais específicos no país coloca o assunto em uma posição vulnerável a questionamentos éticos, morais, médicos, religiosos e sociais. Considerando este cenário de inegável transformação da estrutura familiar, o presente trabalho teve como objetivo principal analisar as repercussões jurídicas da reprodução humana assistida nas uniões homoafetivas. As considerações trazidas por este trabalho sinalizam que mesmo diante de alguns avanços, lacunas importantes necessitam ser preenchidas no âmbito do Direito. Algumas sentenças já foram favoráveis ao reconhecimento da paternidade e maternidade de casais homoafetivos cujos filhos foram gerados por meio de métodos de reprodução assistida, entretanto, as respostas aos dilemas que envolvem esse tipo de cinstituição familiar contemporânea ainda carecem de mecanismos legais mais concretos.
